Organic acids: In recent years, the use of acidifiers has been increased many fold and are found to have the ability to reduce many pathogenic and spoilage organisms by lowering the gut pH. Because of the development and emergence of antibiotic resistant microbes (), the utilization of s has been increased as growth promoters in animal agriculture, which could help in providing protection from adverse human health implications. In poultry diets, the use of s elicits a positive response in performance of broiler growth. In order to inhibit growth of bacteria of intestine (those which compete with host for the nutrients that are available) there is requirement of dietary acidification thereby causing reduced possibility of availability of bacterial metabolites which are toxic in nature. In the ceaca as well as small intestine it has been suggested by a number of studies that s affect the bacterial concentration. In the crop of the poultry birds they are bactericidal for (; ; ). In the young ones, acid production in the gut is insufficient and acidifiers are sometimes used in feeds to compensate it. The use of s such as formic, lactic, propionic, citric, sorbic and phosphoric acids optimizes the balance of the microflora of the gastrointestinal tract (; ; ; ; ). They lower the pH, at which the activity of proteases and beneficial bacteria is optimized and proliferation of is minimized by a direct antibacterial effect destroying their cell membranes (; ; ). In experimental studies, s have been found suitable growth promoters in pigs (; ; ) and poultry (). Supplementation of organic acid also increases intestinal colonization of spp. in chicks (). They are widely used to inhibit pathogens like salmonellae and in their undissociated forms are able to pass through their cell membrane. Inside the bacterial cell, the acid dissociates to produce H+ ions, which lower the pH causing the organism to use its energy in trying to restore the normal balance. It also disrupts DNA and protein synthesis and thus the bacteria are unable to replicate or its replication slows down. Lower pH conditions thus protect the bird from infection especially at young ages. In addition to direct microbial action, recent studies have shown that salt form of s including butyrate, propionate and acetate have shown their ability in reducing colonization in chicken cecum by enhancing innate immune defense via increased synthesis of host defense peptides (, ). Furthermore, s also reduce the contamination of litter with the harmful microorganisms, neutralize ammonia production and diminish the risk of re-infection. The effectiveness of organic acids in poultry may also depend on the composition of the diet and its buffering capacity. The combination of citric, lactic, formic and orthophosphoric acid at doses of 2-8 kg ton-1 of feed are found effective. Propionic acid suppresses the growth of moulds and prevents the formation of mycotoxins. Short-chain s such as butyrate are considered potential alternatives to antibiotic growth promoters. Butyric acid at 0.2% level of incorporation can help to maintain the performance and carcass quality of broilers (). The Medium-chain Fatty Acids (MCFA), caproic, caprylic and capric acid, are also capable of inhibiting the growth of at low concentrations . The ifiers are thus considered effective and recognized as safe, with no concern over getting into human food chain.

N2 - Valproate has been in clinical use for nearly 40 years for the treatment of a variety of neuropsychiatric illnesses, including bipolar disorder and epilepsy. Early reports linked its biochemical mechanism of action to alterations in gamma-aminobutyric acid (GABA)-ergic function. The definitive mechanism(s) mediating the clinical efficacy of this relatively simple molecule remain obscure. Although valproate does not directly interact with postsynaptic GABA receptors, it does increase regional neuronal concentrations of GABA by both inhibiting its metabolism and increasing its synthesis. The relevance of these effects to the clinical efficacy of valproate is unclear. Results of preclinical research, largely in rodents, have implicated ion channels, monoamines, corticotropin-releasing factor, and intracellular signaling proteins in the mechanism of action of valproate. This relative dearth of data in the area of valproate neuropharmacology is also evident when discussing the mechanism( s) of action of other mood stabilizers and anticonvulsants. Modern tools of basic and clinical neuroscience (eg, genomics, proteomics, functional brain imaging) will rapidly provide valuable insights into the precise mechanism(s) of action of valproate.
