Riboflavin

26 Dec 2016

Riboflavin (Lactoflavin, B2 vitamin) is one of the most important water-soluble vitamins, a coenzyme of many biochemical processes. Riboflavin has bright yellow color and a characteristic vitamin smell.

Riboflavin in sport

Riboflavin participates in formation of energy in three main processes:

  • Glucose metabolism
  • Oxidation of fats
  • Transfer of ions of Hydrogenous in Krebs's cycle

Participation of Riboflavin in synthesis of a protein is of special interest for bodybuilders. There is dependence between entering of Riboflavin in an organism and muscle bulk. One research showed what women need high doses of B2 vitamin, for restoration after the trainings. One more research established that Riboflavin in the form of additional additive improves muscular activity at sports activities therefore it is often included in sports delivery.

Deficiency of Riboflavin

Riboflavin is necessary for formation of erythrocytes, antibodies, for a regulation of body height and genocidal functions in an organism. It is also necessary for a healthy skin, fingernails, body height of hair and in general for health of all organisms, including function of a thyroid gland.

External implications of a failure of Riboflavin at the person are lesions of a mucosa of labium with vertical cracks and an exfoliating of an epithelium (cheilosis), ulcerations in mouth angles (an angular steatites), swelled also reddening of tongue (glossitis), seborrhea dermatitis in nasolabial cord, nose wings, ears, centuries. Often also changes from organs of vision develop: a photophobia, cornea vascularization, conjunctivitis, keratitis and in certain cases is a cataract. In some cases at an avitaminosis the anemia and nervous breakdowns which are shown in muscular delicacy, thermalgias in legs, etc. take place. You can try Cerebramin.

The main reasons for a disadvantage of Riboflavin at the person is insufficient consumption of the products containing this vitamin; the wrong storage and preparation of the products containing this vitamin owing to what the content of vitamin sharply decreases; chronic diseases of digestive tract, reception of medicines, being antagonists of Riboflavin.

Food sources of Riboflavin

Riboflavin contains in the following products (in decreasing order of its quantity in 100 g of a product): liver and kidneys of 2.80-4.66 mg, yeast of 2.07-4.0 mg, almonds of 0.80 mg, eggs of 0.30-0.80 mg, champignons of 0.4 mg, cottage cheese of 0.30-0.50 mg, broccoli of 0.3 mg, white cabbage of 0.25 mg, buckwheat of 0.24 mg, milk of 0.13-0.18 mg, meat of 0.15-0.17 mg, and also: the peeled rice, pasta, white loaf, the majority of fruit and vegetables in number of 0.03-0.05 mg.

Content of B2 vitamin in some foodstuff

Product / Content of B2 vitamin, mg / 100 of a product

Beef liver / 2.19

Yeast baking (pressed) / 2.0

Kidneys / 1.6-2.1

Liver / 1.3-1.6

Cabbage / 0.025-0.05

Potatoes / 0.08

Salad / 0.8

Carrots / 0.02-0.06

Tomatoes / 0.02-0.04

Recommended doses

The recommended daily dose averages 1.3 mg, for the adult. In case of occupations bodybuilding, requirement increases up to 3-5 mg. Riboflavin has no toxicity and doesn't cause hypervitaminoze in case of the use inside as its low solubility interferes with its excessive absorption from intestines.

Information from the encyclopedia of sport

Riboflavin. At the heart of chemical structure of Riboflavin (Vit. B2) lies system of izoalloksazin. As a side chain its molecule contains remaining balance of pentatonic alcohol of ribitol owing to what vitamin was called Riboflavin.

In a human body Riboflavin arrives mainly with meat and dairy products, it contains also in fish, yeast, peas, germs and covers of cereal cultures.

Medicines: Riboflavin and Riboflavin mononucleotide.

Pharmacokinetics. Riboflavin is absorbed in intestines and is subject to phosphorylation in a mucous membrane of guts, cells of a liver and blood. At the same time two kofermentny forms are formed: flavinmononucleotids (FMN) and flavinadenindinucleotids (FAD).

Riboflavin accumulates mainly in a liver, kidneys and adrenal glands. In fabrics Riboflavin can be in a free condition, however its nucleotides (FMN and FAD) are reliably connected with proteins of an apoferment. Riboflavin from an organism is emitted with kidneys, painting urine in light yellow color.

Pharm dinamics. Riboflavin as prostetic group flavin (yellow) enzymes performs function of a transporter of hydrogen in the course of tissue respiration and regulates oxidation-reduction reactions. Coenzymes of biological oxidation are intermediate carriers of hydrogen from OVER to tsitokhroma, are a part glutathione-reductase enzyme which translates the oxidized glutathione in got into condition.

As a part of oxidase amino acids Riboflavin takes part in synthesis and exchange of amino acids. In general he normalizes exchange of fats and proteins, plays an important role in maintenance of normal visual function of eyes (synthesis of flasks and rods), and participates in function of mucosa’s, skins and in hemoglobin synthesis. Enzymes which incorporate Riboflavin participate in exchange of other vitamins: pantothenic acid, pyridoxine and folic acid. Riboflavin is necessary for coli bacillus vital activity, and also facilitates iron absorption, increases fastness of an organism to hypoxia and other adverse factors.

Riboflavin mononucleotide is a product of phosphorylation of Riboflavin, ready form of coenzyme.

Precursory symptoms of failure of Riboflavin in organism is dysfunctions of CNS (hypochondria, hysteria, depression), decrease further secretion of a gastric juice and activity of enzymes of intestines, appetite worsens, body weight decreases, the feeling of fever in a body appears, there are cracks in angles of a mouth and on labium (an angular stomatitis), tongue becomes dry, bright red color (glossitis), there is an acute pain in eyes, a photophobia, develop keratitis, konyyuktivit, phacoscotasmus (cataract).

Indications to use: hypo - and ariboflavinosis, diseases of eyes (keratitis, konyyuktivit, helcomas, cataract) and skins (seborrheal eczema, a systemic lupus erythematosus), combustions, a frostbite, a myocardial dystrophy, chronic enteritis, radial illness, failure albuminous and excessive carbohydrate deliveries.

Riboflavin the mononucleotide is used in ophthalmology, dermatology, neurology.

Side effects are observed at over dosage. Riboflavin the mononucleotide causes morbidity in injection site. Treatment by high doses of vitamin owing to its bad solubility can cause an occlusion of canaliculus of nephron.

Riboflavin (B2 vitamin drug). Investigated influence of additional consumption of Riboflavin on physical efficiency of 14 Canadian swimmers of high qualification with the normal status for this vitamin and the regimen of its consumption with a nutrition meeting the recommended standards. Surveyed one subgroup for 16 — 20 days accepted it in a dose of 60 mg a day whereas for surveyed other subgroup drug replaced placebo. Physical working capacity was estimated in the swimming test consisting in sixfold overcoming 50-meter distance freestyle. Besides, in the tredmilny test defined the maximum aerobic power and a ventilating anaerobic threshold. Drug considerably increases visual acuity and fastness to a hypoxia; at the same time consumption of Riboflavin in long tests didn't affect indicators of its level in a blood, on indicators of physical working capacity. The conclusion was drawn that in the course of the sports training swimmers completely can support the normal riboflavin status without additional consumption of this vitamin. Besides, it is obvious, it is necessary to fulfill its dosages for the athletes specializing in firing and also in other sports, taking into account anti-hypoxemic effect.

B2 vitamin in itself has no anabolic activity, and its forms Riboflavin a mononucleotide and Flavinatum which in Ukraine aren't issued — possess. Drugs activate the enzymes participating in synthesis of amino acids, lipids and carbohydrates. They normalize the course of oxidation-reduction processes, cholesterol exchange, strengthen hemoglobin synthesis, accelerate iron absorption, and improve vision. For the growing organism these drugs are an irreplaceable growth factor.

Action mechanism of G - squirrels - the connected receptors

26 Dec 2016

The mechanism of signal transmission is identical at all G squirrels - the connected receptors (And). After accession of receptor conformation changes. Subjedinitsa gives GDF and attaches GTF, then separates from two other subjedinitsa, comes into contact with effector protein and changes his functional state. And β, and at-subjedinitsy are capable to contact effector proteins. a-Subjedinitsa provides slow hydrolysis of the connected GTF to GDF. Ga-GDF has no affinity to effector proteins and again reunites with β, at-subjedinitsami (And).

G-proteins can diffundirovat (lateralno) in a membrane; they aren't connected with a certain type of receptors. Nevertheless between types of receptors and types of G-proteins there is an interrelation (B). a-Subjedinitsy G-proteins differ on affinity and type of impact on effector proteins. Ga-GTF Gg-áåëêà stimulates to an adenilattsik-manhole while Ga-GTF Gj-áåëêà inhibits it. To G - protein - to the connected receptors muskarin holinoretseptor, receptors belong to noradrenaline, adrenaline, a dopamine, a histamine, morphine, prostaglandins, leykotriyena and other substances and hormones.

Effector proteins for G-protein are an adenilattsiklaza (ATP - an intracellular carrier of tsAMF), a phospholipase With (fosfatidilinozitol, intracellular carriers inozitoltrifosfat and diacylglycerin) and some proteins of ion channels (B).

The set of functions as tsAMF increases activity of a protein kinase And which fosforilirut regulatory proteins depends on concentration of tsAMF in a cell. Besides, rising of concentration of tsAMF leads to relaxation of a smooth musculation, rising of force of cordial reductions, intensifying of glycogenolysis and lipolysis. Phosphorylation of proteins of Sa-channels promotes their opening at depolarization of a membrane. It is necessary to notice that tsAMF is inactivated by phosphodiesterase. Therefore inhibitors of this enzyme maintain high cellular concentration of tsAMF and have effect, similar to an adrenaline.

Besides, receptor protein can fosforilirovatsya and thereof loses ability to activate G-protein. This mechanism is the cornerstone of depression of sensitivity of a cell as a result of long stimulation of a receptor under the influence of an agonist.

Activation of phospholipase With leads to splitting of phospholipids of membranes (fosfatidilinozitol-4.5-bifosfata) with formation of inozitoltrifosfat (1P3) and diacyl of Glycerinum (DAG). Inozitol stimulates an exit of Sa2 + from depot that leads to reduction of a smooth musculation, splitting of a glycogen or an exocytosis. Diatsilglitserin stimulates a protein kinase With which fosforilirut defined a serine - and the threoninecontaining enzymes.

Some G-proteins influence proteins of channels and promote opening of channels. Thus are activated by K+ - channels (action of Acetylcholinum at the synoptic level; influence of opioids on transfer of exaltation in nervous cells).

Systems of the secondary messengers connected to G-proteins.

In the table examples of similar receptor systems are given. It is obvious that a large number of primary messengers is regulated some by secondary. Thus, it is necessary to understand that specificity of action of initially communicating ligands is defined by localization of a receptor on certain cells in which secondary messengers cause an expression of the proteins specific to this cell.

Receptors connected to G-proteins

More than 1000 genes encoding the receptors connected to G-proteins are opened. These receptors are monomeric glycoproteins with rather similar amino-acid composition. 7 domains having hydrophobic amino acids as a part of a polypeptide circuit are characteristic of them. These domains are formed by loops in a diaphragm with one end which is coming out, and another - in cytoplasm.

Endogenous ligands communicate on an external section of a receptor. Small by the size, for example amines, join sections in different transmembrane areas whereas large, for example the polypeptides less capable to penetrate into hydrophobic regions communicate on ecstracletoc loop of a N-end section of a receptor. You can also like Cerebramin.

G-squirrels join an intracellular segment of a receptor in the 3rd loop between the 5th and 6th regions. Though the mechanism of the effect arising at connection with agonist isn't up to the end clear, it is supposed that this act stabilizes a receptor in the conformation allowing him to interact with the trimmer of G-proteins, activating them and the subsequent effector events.

The effect of agonist usually has only limited duration that is defined by several processes. The majority connected with G-proteins and receptors Cerina and a treonina in cytoplasmatic loop and in the S-trailer site which can be several kinases that limit interaction between a receptor and G-protein has the remains. This process is called desensitization of a receptor and allows a cage to answer very wide ranges of the concentration stimulating of agents. After long influence of agonist the number of receptors on a plasmatic membrane can be also regulated by the internalization process (which is carried out in certain cases by a catabolism), or down-regulation of a receptor. Though the signals causing her aren't clear, it is represented that they are excellent from controlling desensitization.

G-proteins

Carry out transduction of a signal from membrane receptors to effectors enzymes and ion channels. Each of these proteins consists of three separate subunit designated α, β at as decrease in molecular weight; the α- subunit of the trimmer and is the chief intermediary of influence of G-proteins on their effector. The main function β-and γ-subunit of the trimmer is support of interaction of a α- subunit with a plasmatic membrane and receptors, however they are capable also to direct regulation of effector.

Families of G-proteins mammals

The G-squirrels participating in transmembrane transfer of a signal are regulated by the general mechanisms. In the drawing their cycle of activation and an inactivation is presented. In a basal state three subunit of G-proteins are connected together and with guanozindifosfat (GDF), attached to α- subunit. When agonist connects to a receptor, GDF separates, and the place freed on α- subunit is taken guanozintrifosfat (GTF), a lot of present at cytoplasm.

Emergence of this communication stimulates G-proteins, as a result of α- subunits separate from a receptor and from β, γ- subunit and contacts effector. Several seconds later Gtfaza who is available in α- subunit hydrolyzes the connected GTF to GDF that leads to an inactivation of subunit. The α- subunit connected with GDF separates from effector and again is associated with β-, a γ-complex of G-proteins of G-proteins, becoming capable to a new cycle of activation by receptor.

The functional distinctions between members of family of G-proteins initially are defined by differences in the α- subunits. The nomenclature of G-proteins was initially built according to their function. So, the designations Gs and Gi are accepted for the G-proteins stimulating and inhibiting respectively. The designation Gi was entered earlier when for the first time the G-protein discovered in a retina was called transdutsin.

Imperfection of this nomenclature became obvious after separation and cloning of G-proteins with the obscure function. So there were designations Go, Gq, then G11, G12, etc. Some G-proteins expressed only in certain types of cells, for example Gt is found only in sticks and cones of a retina where activates a tsGMF-specific fosfodiesteraza. Other G-proteins, on the contrary, in the majority of fabrics and have multiple function, for example, Gi is present at the majority of cells, inhibiting, but is capable also to direct impact on some ion channels.

The influence of the majority of G-proteins on effectors is stimulating however some inhibit them. For example, G0 inhibits Sa2+-channels in a brain and heart; Gs stimulate, a Gi inhibits. The last two G-proteins are in turn regulated by different groups of receptors which are often provided in one cell. Result of simultaneous activation of the stimulating and inhibiting receptors is reduction and mitigation of response.

This double regulation in addition to interaction of other following behind proteins of components of signal system provides the integrated response of a cell to numerous incentives.

Effector enzymes regulated by G-proteins. From three components providing the carrying out a signal interfaced to G-proteins, it is the most difficult to study effector links at the molecular level. Only recently some of enzymes of this link were isolated and cloned.

Effects hormonal and receptors most often are implemented through adenilattsiklaza and phospholipase of Page. Other enzymes, such as A2 phospholipase producing arakhidon acid also, apparently, are regulated by G-proteins, however these responses are up to the end not clear.

Adenilattsiklaza and tsAMF as a secondary messenger

Cyclic AMF (tsAMF) is synthesized from ATP by adenililtsiklaz enzymes which are built in a plasmatic diaphragm.

It is represented that these enzymes are the big polypeptides containing two clusters from six transmembrane segments separating two similar catalytic domains. Is available, on extreme a Mercedes, eight forms of adenilattsiklaza. All of them are stimulated with Gsα, but differ on sensitivity to the inhibiting influence of Gα-stimulation in calmodulin (calcium/calmodulin) and on effect β, at-subunits G-proteins. These additional regulators give ability to integrate many signals influencing different systems of secondary in one cell.

Cyclic AMF shows the effect in a cage, generally activating tsAMF-dependent proteinkinaza (a proteinkinaz of A, PKA). These tetrameasured enzymes consist of two regulatory and two catalytic subjedinitsa. Enzymes are activated when two molecules tsAMF join each regulatory subunits, releasing catalytic subunits from tetrameasure. The released subunits catalyze transfer of phosphatic group of ATP on the specific serinov or treaninon remains of proteins targets. Among them there can be enzymes which participate in metabolic processes of cage, and the proteins regulating a gene transcription. The metabolic way activated by tsAMF making the cascade of enzymatic activation leading to disintegration of a glycogen in liver is well studied, for example. The activated proteinkinaza and fosforilirut fosforilazny kinase (phosphorylase kinase) which in turn fosforilirut glikogenfosforilaza is enzyme catalyzing disintegration of glycogen.

Action of tsAMF on a transcription of genes is mediated catalyzed protein and phosphorylation of the protein known under the name cAMP response clement-binding protein (CREB) which joins the specific short sequences of DNA known as cAMP response elements (CRE). CREB joins CRE, being fosforilirovan and that stimulates a transcription of the genes supporting CRE in regulatory zones.

Phospholipase with and phospholipid secondary messengers

Representatives of family of G-proteins integrate various receptors to group of the enzymes famous as phospholipases cf. These enzymes concern to big family of phospholipases for which substratum are inozitolfosfolipida. The alarm transduction in this way attracts the sequence of molecular events similar with observed in case of activation of an adeiilattsiklaza. Linkng of agonist with a receptor activates G-protein which in turn joins a phospholipase on an internal surface of a plasmatic membrane. The activated lipase quickly turns fosfatidilinozitolbifosfat (PIP2) in inozitoltrifosfat (IP3) and diatsilglitserol. Both of these molecules work as secondary messengers in two various ways: IP3 the small water-soluble molecule capable to diffundir quickly in cytoplasm and to join 1RZ-dependent calcic channels in a smooth endoplasmic retikulum, releasing calcium inventories in cytosol.

Increase in concentration of Sa2 + in cytoplasm initiates a wave of Sa2+ reactions in a cage, many of them are mediated by specific Sa2+ proteins from which the calmodulin is most widespread. Sa2+-kalmodulin regulates a number of enzymes, including Sa2+-zavisimuyu to ATFAZ of a plasmatic membrane which extorts calcium from a cage, and as it was told earlier, some types of adeiilattsiklaza. The majority of effects of calcium in a cage is result of activation of group proteinkinaz, known as Sa2+-calcium module depending proteinkinaza. These kinases fosforilirut seri-new and treonin remaining balance of various proteins. Thus, again physiological response to activation of phospholipid secondary messenger in each cage depends from ekspres in it the proteins which are target Sa2+.

Other molecular product of hydrolysis of PIP2 a phospholipase With is äèàöèëãëèöåðîë. This lipidic molecule remains in a plasmatic diaphragm where together with fosfatidilseriny the serin-treoninovykh êèïàç, known as a proteinkinaza of Page activates some members of other family. These soluble kinases peremetatsya in a diaphragm in response to increase in calcium in ïè ãî to a spinning top (IP3 caused by release) and then are activated by combined influence of Sa2 + a diatsilglitserola and a fosfatidilserina. Being activated, these kinases fosforilirut groups, specific to a cell, the substratnykh of proteins which include many ion channels, receptors and other kinases that as a result increases a gene transcription.

Other processes of signal transduction regulated by G-proteins. In addition to the described enzymes it was shown quite recently that G-proteins modulate also activity voltazh depending ion channels. Apparently from the table, many hormones and neurotransmitters regulate both secondary messengers, and the ion channels, activating one G-protein. In particular, Gt stimulates both adenilattsiklaza, and some types of Sa2+-channels.

Obviously, further clearing up of mechanisms of direct and reverse regulation of receptor systems of a signal transduction is one of the most important scientific tasks of the future.

Modern studies of Amyotrophic lateral sclerosis

26 Dec 2016

Neurologist Dr. Doping tells about corpuscles Bunin, the impact of stress on neurons and gene mutation in neurodegenerative diseases.

Amyotrophic lateral sclerosis - a severe neurological disease that is characterized by progressive loss of neurons responsible for movement and thought processes. It manifested it gradual muscle weakness. The person loses the ability to move his arms, legs, impaired breathing and speech. A few words about the history of this disease. The first description of the structure of motor and sensory waves that come within the nervous system, was done in the 30s of the XVIII century, when Magendie described this division. Until now, it is a fundamental principle of the anatomy of the nervous system.

n the future, it has been described by a number of cases where the death of nerve cells caused muscle weakness, atrophy and paralysis in humans. In those days it was not obvious that the weakness may be caused by damage to the nervous system at different levels: at the nerve cell level in the brain, spinal cord, peripheral nerve cells, and therefore those descriptions, which combined clinical and anatomical studies have been published and widely discussed. As a result, all the glory from the description of ALS as the disease got famous neurologist Charcot, who in 1874 identified the disease as an independent unit, and said that progressive muscular paralysis with atrophy caused by the death of nerve cells in the brain and spinal cord, are called amyotrophic lateral sclerosis. Now it is his description. Kozhevnikov The first description was made in Russia in 1883. Important national contribution to the study of this disease was to describe the so-called cells Bunin - is oxyphilous activate nerve cells - in 1962. These inclusions are still studied and described in all textbooks - both domestic and international - under the eponym "Bunin calf."

Interestingly, in the definition of the disease appear the word that is the death of cells responsible for movement. In fact, if you deeply understand the problem, it is not about individual cells, but the cells of the system. Even Charcot suggested that, having been born in one part of the nervous system, the disease is spreading in several of its departments. Then we necropsy found that the characteristic intracellular inclusions formed neurons in the motor cells, and the cells of the frontal lobe, responsible for planning actions for thinking. Then clinical descriptions have confirmed that these people are memory disorders - not only for the movement responsible damaged elements of the nervous system. Then geneticists have shown that the same mutations can lead some people to the movement disorders, while others - the memory disorders. Then came the researchers, who tied it into a kind of evolutionary theory and said that the BAS system are damaged, which has consistently developed in the framework of evolution, namely responsible for the grasping hand movements, walking upright, speaking and socializing.

To improve brain functions use CogitumSemax, Noopept, Phenylpiracetam.

Traditionally, the mechanisms that are responsible for the emergence and development of the disease include toxicity, oxidative stress, disturbance of axonal transport, a lack of neurotrophic factors. But nevertheless it is still not entirely clear why the disease develops in adulthood. Why do some patients with the same mutation in the disease appears, and the disease does not develop their relatives? In 2014 he published an article that analyzed quite common known epidemiological data and made the assumption that the ALS is a multistep process. To people sick, you need to go through 6 stages. This means that the mechanism of disease, each of these mechanisms play a role, but it can not run on their own process. This greatly complicates the study when it is necessary in some human populations to identify not just one factor that leads monogenic disease, and when it is necessary to identify the presence of a combination of this gene with certain environmental factors. Nevertheless, these factors continue to be studied. For environmental factors include smoking, physical activity, injury, participation in armed conflicts, pesticides, some others. As for genetic factors that are considered launchers in this disease, they are known to date, approximately 10% of all people who suffer from this disease. We can talk about 20-25 genes that increase the predisposition of the disease. Four of them are the most common: the SOD1 gene, first open in this disease, TDP43 gene, and the FUS gene C9orf72 gene, which was opened in 2011 and has led to a rethinking of the mechanisms of this disease.

Now we will talk about how to change our understanding of the mechanisms of development of the disease after the discovery of mutations in the gene C9orf72. Mutation of this hidden due to the fact that it is located in the intron of the gene. And this mutation refers to the expansion of the hexa-nucleotide repeats, ie, needed specific genetic methods to detect this mutation. How does it work? Apparently, due its pathological effect in that on the basis of DNA in which an excess amount of hexa-nucleotide repeats accumulates to a few thousand as compared with 20 normal, several thousands of repetitions, that is, words that are recorded within the genome correctly but they obsessively repeated. The result is an excess portion of the RNA that does not encode any protein. Why think so? Because there is no so-called start-codon, which begins with the protein translation.

But it turned out that there is a mechanism by which the protein can be broadcast in the absence of the start codon. The result is a protein consisting of the b-peptides which may be toxic and in this disease. What can these proteins? They are formed in the cytoplasm and bind to RNA, which is also in the cytoplasm are located there for the translation process. As a result of impaired interaction with other proteins of RNA. Critical, apparently, it becomes in a stressful situation, because it is known that in neurons under stress - asthmatic stress or stress in the form of increased temperature or oxidative stress - the stress granules are formed. This aggregation link RNA to proteins. These proteins with prion sequences protect RNA from degradation by proteases, making it more resistant to stress. Then the stress granules at the end of the stress decay, and extend all the processes associated with the formation of proteins, RNA transport.

So, these bi-peptide proteins that are produced in excess RNA, blocking the dynamics of stress granules, and do not break after the stress is finished. As a result, they accumulate within the cytoplasm of cells, and they contain a variety of proteins. All this repeatedly confirmed histologically. These are the inclusions that are typical for this disease. What do we get? Neuron affected by stress, can not be restored - this is the first problem, that is, can not go on the formation of proteins from RNA. The second problem - when proteolysis resistant accumulate inside the cell clusters, which include various RNA proteins, and this in turn triggers a series of pathological processes.

Modern research to find treatments focused on the processes associated with the formation of a bi-peptide proteins, ie they block the pathological broadcast. They just stop it with the C9orf72 gene. It is known that a complete blockade of the formation of this protein is not lethal to cells and, as shown by experiments, slows down or completely stop the disease in animals that have this mutation, and without such a treatment would be sick bass, but with treatment, this process stops. On the basis of these studies, carried out a search for new disease markers, because there is a search for methods of these bi-peptide proteins in the cerebrospinal fluid. This marker can be used both for diagnosis and for monitoring treatment of disease. If the amount of treatment by the action of the bi-peptide proteins decreases, then the treatment is effective. This makes it possible to accelerate clinical research.

Now one of the basic models of disease - a model for pluripotent stem cells, when the patient ALS mutation C9orf72 taken, for example, fibroblast, i.e. a piece of skin, and is under the influence of special factors converted into neurons, which also suffer from his own neurons. And research on these neurons allow to accelerate new drug discovery process as we can test drugs in much larger quantities and much faster than we could do it on a human. That is, the discovery of this mutation has allowed us to move forward in the development of models of disease and in the development of markers for the diagnosis and monitoring of treatment and the search for new treatments for themselves. And it confirmed the existence of a relatively new and newly discovered mechanisms of broadcasting without a start codon. Science has made thanks to the disease a significant step forward, and we hope that it will be effective in relation to drug discovery.

Characteristics substance Chlordiazepoxide
Anxiolytic, benzodiazepine derivative.

White or light yellow crystalline powder. Practically insoluble in water, it is soluble in alcohol; as the hydrochloride - is soluble in water.

PharmacologyMode of action - anxiolytic, sedative, hypnotic, muscle relaxant, central.

Interacts with specific benzodiazepine receptors located in postsynaptic GABAA receptor complex in the cerebral cortex, amygdala, hippocampus, hypothalamus, cerebellum, striatum, and spinal cord. Increases the sensitivity of neuronal GABA receptors to GABA enhances GABA neurotransmission, blocks polysinaptic reflexes.

After oral administration, it is well absorbed from the gastrointestinal tract (food slows absorption); Cmax when administered single dose reached after 0.5-4 hours and the equilibrium concentration in the blood is 5-12 days after the beginning of reception. Plasma protein binding is 96%. T1 / 2 chlordiazepoxide from plasma is 7-28 hours, the Cmax of the main metabolite (desmethyl-chlordiazepoxide.) - 8-24 hours The liver is intensive metabolism (N-demethylation, deamination, hydroxylation) to form active derivatives (desmethyl-chlordiazepoxide, demoksepam , desmethyl-diazepam, oxazepam). It passes through GEB, placenta, enters the breast milk; slowly absorbed from the muscle tissue. After the treatment, the metabolites found in the plasma for a few days or even weeks. T1 / 2 - 5-30 hours (chlordiazepoxide), 18 hours (desmethyl-chlordiazepoxide), 14-95 hours (demoksepam), 30-100 hours (dezmetildiazepam), 5-15 hours (oxazepam). Report mostly kidneys (1-2% unchanged). Accumulation of chlordiazepoxide and its active metabolites with repeated use significantly.

Older people chlordiazepoxide absorption and metabolism are slower, significantly slowing down the metabolic transformation at the defeat of the liver.

It has a marked sedative effect on the central nervous system. It suppresses the alarm, excitement, emotional stress. Weakens the obsessions and fears, increases susceptibility to hypnosuggestive therapy. Has anti-panic effect, it relieves tremors, has a weak anticonvulsant effect. It reduces the severity of anxiety and fear associated with the upcoming surgery.

In large doses, can reduce agitation. Exhibits mild hypnotic effect which is expressed usually in the first 3-5 days of treatment, further positive effects on sleep due to the elimination of various psychogenic stimuli. It causes moderate muscle relaxation.

Relieves the symptoms of acute alcohol withdrawal symptoms such as agitation, nervousness, anxiety, anxiety, tremors, and others. Increases appetite, it has a weak analgesic effect.

Reproduction studies in animals showed that the introduction of chlordiazepoxide in rats at doses of 10, 20 and 80 mg / kg / day did not cause of congenital malformations and disorders of neonatal growth, as well as violation of lactation in females. In another study, when administered dose of 100 mg / kg / day a significant reduction in the fertilization rate was revealed marked reduction of body weight and survival in neonatal rats.
