Mycophenolic acid pharmacokinetics - absorption and clearance

Bullingham so that, regardless of oral or intravenous administration, MMF can be rapidly and extensively absorbed by the body, and its active metabolites before the loop entirely the product of mycophenolic acid. Two routes of MPA concentration-time curves are similar. The average time to peak of mycophenolic acid (tmax) approximately 1h. The average half-life of mycophenolic acid (t1 / 2) is about 17h, prompt medication twice a day is more appropriate. Two routes of mycophenolic acid concentration - time area under the curve (AUC ∞) was no significant difference, about 105mg.h / L. Mycophenolic acid excretion into the urine by tubular secretion. MMF oral radiolabeled dose administered can be completely recovered, of which 93% appears in the urine, 6% in feces, most of the type to MPAG by the urine, traces of the type of MPA excreted by the urine . Shaw and other three factors that regulate clearance of mycophenolic acid: (1), liver, gastrointestinal tract UGT; (2) MPA-EHC; (3) of mycophenolic acid freeness. Mycophenolic acid clearance can cause major changes or related factors include: acute or chronic renal insufficiency, with immunosuppressive agents such as CsA and corticosteroids, time after transplantation (Another possible factor for the ethnic differences.

Actidione’s risk

Because cycloheximide has a very strong toxicity, including damage to DNA, leading to fetal malformations and other effects on reproduction (including birth disorders and sperm toxicity), it is generally only used in vitro research applications,  Actidioneis not appropriate use of antibiotics in the human body as a. In the past Actidione was used in agriculture as a fungicide, but because of its increasing awareness of the dangers of this usage has been very small. Alkali can destroy cycloheximide, so if the work surface or container contaminated by cycloheximide harmless as long as the use of alkaline solution (such as soap) to wash it. In vitro applications in molecular biology cycloheximide can be used to determine the protein (enzyme) half-life. Using cycloheximide-treated cells, and then use the western blot (Western blot) experiments to show the protein to be studied over time, the number of changes. Because cycloheximide hinder protein synthesis, decreasing protein within the cell.

Mupirocin Resistance

Shortly after the clinical use of Mupirocin began, strains of Staphylococcus aureus that were resistant to mupirocin emerged. [10] Two distinct populations of mupirocin-resistant S. aureus were isolated. One strain possessed low-level resistance, MuL, (MIC = 8 -256 mg / L) and another possessed high-level resistance, MuH, (MIC> 256 mg / L). Resistance in the MuL strains is probably due to mutations in the organism's wild-type isoleucinyl-tRNA synthetase. In E. coli IleRS, a single amino acid mutation was shown to alter mupirocin resistance. MuH is linked to the acquisition of a separate Ile synthetase gene, mupA. Mupirocin is not a viable antibiotic against MuH strains. Other antibiotic agents such as azelaic acid, nitrofurazone, silver sulfadiazine, and ramoplanin have been shown to be effective against MuH strains.
The mechanism of mupirocin differs from other clinical antibiotics, rendering cross-resistance to other antibiotics unlikely. However, the MupA gene may co-transfer with other antibacterial resistance genes. This has been observed already with resistance genes for triclosan, tetracycline, and trimethoprim.

Pristinamycin Clinical use

Despite the macrolide component,  Pristinamycin is effective against erythromycin-resistant staphylococci and strepcococci.  Importantly, Pristinamycin is active against methicillin-resistant Staphylococcus aureus (MRSA). Its usefulness for severe infections, however, may be limited by the lack of an intravenous formulation owing to its poor solubility. Nevertheless it is sometimes used as an alternative to rifampicin + fusidic acid or linezolid for the treatment of MRSA.
The lack of an intravenous formulation led to the development of the pristinamycin-derivative quinupristin / dalfopristin (ie, Synercid), which may be administered intravenously for more severe MRSA infections.

the application of rapamycin

Inhibition of the target of rapamycin signalling pathway by genetic or pharmacological intervention extends lifespan in invertebrates, including yeast, nematodes and fruitflies.
Researchers reported that rapamycin extended median and maximal lifespan of both male and female mice when fed beginning at 600 days of age. On the basis of age at 90% mortality, rapamycin led to an increase of 14% for females and 9% for males. The effect was seen at three independent test sites in genetically heterogeneous mice, chosen to avoid genotype-specific effects on disease susceptibility. Disease patterns of rapamycin-treated mice did not differ from those of control mice. In a separate study, rapamycin fed to mice beginning at 270 days of age also increased survival in both males and females. Thus, rapamycin may extend lifespan by postponing death
from cancer, by retarding mechanisms of ageing, or both.
Systemic lupus erythematosus and Sjogren's syndrome are chronic inflammatory diseases characterized by the dysfunction of T cells, B cells, and dendritic cells and the production of antinuclear autoantibodies. The mammalian target of rapamycin in T and B cells has been successfully targeted for treatment of systemic lupus erythematosus with rapamycin or sirolimus both in patients and animal models.
A study showed that rapamycin in concentrations of 1-10 nmol / l arrested the
cell cycle progression of Hl-60 cells in the G1 phase, without evident.
cytotoxic effect. At concentrations higher than 10 nmol / l, rapamycin exerted
a significant proapoptotic effect, with the collapse of mitochondrial potential
and caspase-3 activation.

Rapamycin application

Rapamycin is an FDA-approved immunosuppressive and cardiology drug. It
is also an inhibtor of mammalian target of rapamycin (mTOR) pathway. mTOR controls many processes involved in metabolism and response to stress. Rapamycin may benefit animals at risk of cancers
In mammals, target of rapamycin is best known to regulate translation through the ribosomal protein S6 kinases (S6Ks) and the eukaryotic translation initiation factor 4E-binding proteins. Consistent with the contribution of translation to growth, target of rapamycin regulates cell, organ, and organismal size. The identification of the tumor suppressor proteins tuberous sclerosis1 and 2 (TSC1 and 2) and Ras-homolog enriched in brain (Rheb) has biochemically linked the target of rapamycin and
phosphatidylinositol 3-kinase (PI3K) pathways, providing a mechanism for
the crosstalk that occurs between these pathways.
Target of rapamycin is emerging as a novel antitumor target, since the target
of rapamycin inhibitor rapamycin appears to be effective against tumors
resulting from aberrantly high PI3K signaling.

Streptococcus Thermophilus development background

 

By purchasing a starter of Streptococcus thermophilus and Lactobacillus bulgaricus, yogurt can be made at home with a simple recipe. These probiotic cultures are available most health food stores, online, and even in the health food section of some grocery stores. Boil one quart of milk, preferably 2% or whole milk, then removeStreptococcus thermophilus   from heat and cool to between 104 degrees and 114 degrees. It is important to use a sterile container to pour the milk into. Add a generous teaspoon-or the appropriate amount listed on the package instructions-of the yogurt starter. Stir, cover, and incubate at 104 to 110 degrees for six to ten hours. Refrigerate.
This constant incubation temperature is a very important part of the process. Those that have trouble maintaining this temperature might want to consider purchasing a yogurt maker, which regulates temperature.
The process behind this yogurt  Streptococcus thermophilus is beneficial to digestive health in a couple of ways. The good bacteria ferment the sugar in the milk, also known as lactose. The lactose is transformed into lactic acid, which is highly effective in preventing lactose intolerance. The production of the lactic acid reduces pH and results in the milk curdling and turning tart. This also prevents the growth of bacteria that causes food poisoning.

Bacitracin History

The drug's unique name derives from the fact that it was isolated by John T. Goorley from a girl named Tracy:
One strain isolated from tissue debrided from a compound fracture of the tibia was particularly active. We named this growth-antagonistic strain for the patient, "Tracy I." When cell-free filtrates of broth cultures of this bacillus proved to possess strong antibiotic activity and to be non-toxic, further study seemed warranted. We have called this active principle "Bacitracin." It was approved by FDA in 1948.Synthesis
Bacitracin is synthesised via what is called nonribosomal peptide synthetases (NRPSs), which means that ribosomes are not involved in its synthesis.bacABC is involved in synthesis.
Main article: Bactoprenol phosphate
Bacitracin interferes with the dephosphorylation of the C55-isoprenyl pyrophosphate, a molecule that carries the building-blocks of the peptidoglycan bacterial cell wall outside of the inner membrane.
Bacitracin has been claimed to be a protein disulfide isomerase inhibitor in cells, but this is disputed by in vitro studies.

Bifidobacterium bifidum Cell structure and Ecology

Bifidobacteria are Gram-positive, anaerobic, nonmotile, and non spore forming.[14] The characteristic rod or clubbed shape of  Bifidobacterium bifidum varies from 0.5-1.3 μm x 1.5-8 μm. They can be found either living independently or associated in clusters and V-shaped pairs. These bacteria are commonly found curved and in a branched conformation. Bifidobacterium bifidum ferments oligosaccarides in the gastrointestinal tract. Approximately 10% of the total Bifidobacterium bifidum is used to help the body properly breakdown and adsorb sugar. It does this by coding for ABC transporters, permeases, and proton symporters as opposed to phosphoenolpyruvate-phosphotransferase systems.

Bifidobacteria constitute approximately 90% of the microbiota found in the intestines of breast-fed infants. Infants delivered via caesarean section and who are formula fed as opposed to vaginally delivered and breast-fed have significantly lower gut populations of bifidobacteria.The specific breakdown of bifidobacterial species varies but the major contributors include: B. brevi, B. longum, B. pseudocatenulatum, B. adolescentis, B. pseudolongum, and B. bifidum.The number of bifidobacteria in the fecal flora of adults, however, is much lower around 3-6%. Numerous studies have been conducted that illustrate a variance of gut microbiota both by subject as well as with subject age. Bifidobacterium bifidum is also found, although to a much lesser extent, in breast milk, the mouth, and the vagina.

The efficacy of Lactobacillus fermentum

Cholesterol ReductionOne of the ways in which Lactobacillus fermentum has been seen as a probiotic is by its ability to reduce cholesterol levels. Tests conducted using several strains of Lactobacillus and cholesterol broths demonstrated that lactobacillus fermentum had the largest removal of cholesterol. One of the mechanisms by which L. fermentum may remove cholesterol through in vivo is by the absorption of cholesterol, which as a result accelerates cholesterol metabolism. Another method is by the incorporation of cholesterol in the host body into its cell membrane or walls. This would also increase resistance of the bacterial cell membranes to environmental challenge. A third mechanism is by causing the body to consume more cholesterol. L. fermentum would interfere with the recycling of bile salt and facilitate its elimination, which as a result would increase the demand for bile salt made from cholesterol.
 Lactobacillus fermentum ME-3The strain Lactobacillus fermentum ME-3 has recently been discovered and identified as an antimicrobial and antioxidative probiotic. This strain of Lactobacillus fermentum was discovered from the analysis of human fecal samples in 1994. One of the important characteristics of a probiotic microbe is the tolerance to conditions in the digestive tract. Tests conducted on the ME-3 strain in different bileconcentrations found that it was able to survive without large loss in numbers. It has also been found that Lactobacillus fermentum ME-3 has a tolerance to survive drops of pH levels. It can withstand a drop in values ​​from 4.0 to 2.5 without decreasing in numbers. These characteristics of tolerance to bile concentrations and pH levels serve to classify ME-3 as a probiotic.Read more ：http://www.acid-lactic-bacteria.com/lactobacillus/Lactobacillus-fermentum/

Bifidobacterium Longum benefits

Therefore, it assists the body in "maintain [ing] a healthy balance of intestinal flora by producing organic compounds-such as lactic acid, hydrogen peroxide, and acetic acid-that increase the acidity of the intestine and inhibit the reproduction of many harmful bacteria . "Several studies involving the benefits of Bifidobacterium longum have been conducted on both humans and animals with positive outcomes. One such study suggested that B. longum contained both antimutagenic and anticarcinogenic properties as asserted that the lactic acid produced by Bifidobacterium longummay have an affect on tumor cells. The study that was conducted to test this hypothesis involved rats and concluded that the "dietary administration of lyophilized cultures of Bifidobacterium longum resulted in significant suppression of colon tumor incidence and tumor multiplicity and also reduced tumor volume." In other words, this "study on rats with colon cancer showed that Bifidobacterium longum prevented the cancer from spreading and stopped tumors from growing."

Fusidic acid’s Resistance

Because the drug is not licensed for use in the U.S., there are no Clinical and Laboratory Standards Institute standard definitions of fusidic acid resistance. However, in vitro susceptibility studies of U.S. strains of several bacterial species such as S. aureus, including MRSA and coagulase negative Stahylococcus, indicate potent activity against these pathogens^。

In the UK and Australia, susceptibility is defined as a minimum inhibitory concentration (MIC) of 0.25 mg/l or 0.5 mg/l or less. Resistance is defined as an MIC of 2 mg/l or more. In laboratories using disc diffusion methods, susceptibility for a 2.5 µg disc is defined as a zone of 22 mm or more, and resistance is defined as a zone of 17 mm or less; intermediate values are defined as intermediate resistance.

Fusidic acid’s Dosing

Fusidic acid should not be used on its own to treat S. aureus infections when used at low drug dosages. However, it may be possible to use fusidic acid as monotherapy when used at higher doses.^[3] The use of topical preparations (skin creams and eye ointments) containing fusidic acid is strongly associated with the development of resistance,^[8] and there are voices agitating against the continued use of fusidic acid monotherapy in the community.^[6] Topical preparations used in Europe often contain fusidic acid and gentamicin in combination, which helps to prevent the development of resistance.

The role of Streptococcus thermophilus

Streptococcus thermophilus is considered to be "generally recognized as safe sex (GRAS)" component, widely used in the production of some important fermented dairy products, including yogurt and cheese (such as Switzerland, Limburg cheese). Streptococcus thermophilus also has some functional activity, such as the production of extracellular polysaccharides, bacteriocins and vitamins. In addition, Streptococcus thermophilus can be used as a potential beneficial bacteria, has proved its health effects, transport activity and certain gastrointestinal adhesion. Therefore, we need to explore different Streptococcus thermophilus ability to produce different metabolites, not just the amount of lactic acid fermentation. Streptococcus thermophilus to improve the intestinal micro-environment, reduce the intestinal pH, and promote bowel movements to prevent pathogen colonization, bacteria inhibits the secretion of growth of pathogenic bacteria. Streptococcus thermophilus can regulate blood pressure, inhibition of cholesterol synthesis activity, lower serum cholesterol levels, and its fermentation products can be adjusted to control blood pressure Streptococcus thermophilus have anticancer effects, the resulting polysaccharides, bacteriocins, lactic acid and other anti-tumor activity role, through the activation of the immune system, inhibit cell mutation to resistance to tumors.

Bifidobacterium Longum development process

As the last two decades the rise of micro-ecology and medical progress of the revolution, so that bifidobacteria are increasingly recognized the importance of research. Because Bifidobacterium products can be widely used in the world, the masses have been aware of its importance. Infants and young children in particular, can provide a unique intestinal health protection, effectively reduce the incidence of infant intestinal infection rate. The main role of bifidobacteria and widely used, but also for the study of Bifidobacterium laid the basis for development. After many experts and scholars continue to explore experiments have confirmed that most intestinal bifidobacteria is beneficial bacteria, bifidobacteria are disappearing is to reduce the number of "unhealthy" status symbol, bifidobacteria are a barometer of human health. Micro-ecological studies in healthy volunteers found that the number of bacteria in the digestive tract of 100 species, their number reached 100 trillion. Group of human gut bacteria changes with the age increase significantly. Baby 3 to 4 days after birth appears intestinal bifidobacteria, the number of infants bifidobacteria account for about 25% of the total intestinal bacteria; increases with age, bifidobacteria gradually reduced or even disappear, over the age of 65 the elderly, the number of bifidobacteria decreased to only 7.9%, while gas production pod Clostridium, E. coli and other bacteria, a significant increase in corruption; to old age is full of corruption within the intestinal bacteria, bifidobacteria had almost disappeared. Spoilage bacteria in the gut break down food components to produce ammonia, amines, ammonia, sulfide, skatole, indole, phenol, and nitrosamines and other toxic substances, long-term absorption of these toxins in the body, will accelerate aging, cause cancer, caused by arterial sclerosis, liver disorders and other diseases. Increase the number of bifidobacteria in the body in two ways: "nourishing viable in vitro" and "viable in vivo proliferation." "Nourishing viable in vitro" is the oral administration of a certain number of viable Bifidobacterium system.
