Metabiotics as Potential Therapeutic Agent in Mucosal Immunity

Synbiotics area mixture of pre and probiotics and considered an economical and safe substitute for treating infectious and non infectious diseases and improving human health. Synbiotics stimulate native gut microbiota to promote health. Prebiotics and undigested dietary polysaccharides support the progression of probiotics and concurrently destroy the actions of opportunistic germs in the colon. Synbiotics maintain gastrocolic microbial equilibrium and avoid dysbiosis. Metabiotics are the cellular or assistant substance of probiotics and have advantageous importance in tackling many disorder rsrelated to the enteric and systemic milieu. One of the essential metabiotics is short-chain fatty acids, which is considered its epigenetic medicine for cancer therapy. Synbiotics optimize the attentiveness of gut associated metabiotics to modulate enteric physiopathology. Synbiotic therapy might be the future therapeutic modality for managing and curing various ailments..

Approaches to Method Development, Suitability and Validation for Alternative Sterility Test Methods for Complex Parenterals

Advancements in pharmaceutical development have led to increased diversity in drug and biological products. From simple aqueous formulations to advanced drug delivery systems, including sustained release depots, nanospheres and microsphere suspensions, as well as the rise of cell and gene therapy products. With this progress, increased complexity in the manufacture, testing and quality control release of these products has been observed. For injectable products, sterility testing at release is a mandatory step in the product release process. While there are limitations in traditional sterility testing, the final sterility test provides additional sterility assurance for the safety of the product being delivered to the patient. Traditional sterility tests are determined by the visual inspection of nutrient media to assess for the presence of microbial proliferation; product formulations can interfere with visual inspection and ultimately will always lead to a subjective result. Typically, following the initial incubation period, samples of the incubated broth are transferred to fresh nutrient media, and a further incubation step is applied prior to visual inspection.

By Adopting Adenosine Triphosphate (ATP) bioluminescence as the detection platform, the subjective assessment can be avoided, with an unequivocal result determining the presence or absence of microbial proliferation. This technique also avoids the subsequent incubation step on sampling from the sterility test containers.

All living organisms contain the ATP and the enzyme Adenylate Kinase (AK) as part of their biochemical processes, during the ATP Bioluminescence test, an enzyme cascade amplifies the presence of microbial ATP and detect the presence of contamination in the test sample

Characterization of Endophyte Microbiome Diversity in Chia Plant (Salvia hispanica L.)

A total of 9347 fungal and bacterial endophytes were isolated from the roots, stem and leaves of chia plant. Roots harbored more number of fungal endophytes than either stem or leaves whereas stem supported more number of bacterial endophytes than either roots or leaves. The nutritious plant supported more of gram negative compared to gram positive bacterial endophytes. The most common bacteria isolated were Pseudomonas Bacillus, and Cocci. The fungal endophytes isolated from root, stem and leaves of the chia plant showed the presence of Penincillium, Aspergillus, Fusarium, and Macrophomina spps. Dominant fungal endophyte was Aspergillus spp. which was found in all the plant parts instigated. Roots of the plant possessed maximum nitrogen fixers followed by stem and leaves. A proportion of 55% for the bacterial endophytes isolated from the plant chia plant were able to fix nitrogen whereas 25% were able to solubilize phosphorous. The phosphate solubilization efficiency was found to be highest for the Aspergillus spp at 83%.

The Risk of Conflating Child Neglect with Viral Induced Haploinsufficiency

A proper defense against alleged child neglect can be challenging. Accurate convictions by prosecutorial teams are especially important, as most exonerations do not include child neglect conflation. Common signs and symptoms of child neglect include failure-to thrive, cerebellar ataxia, seizures, and epilepsy. Here we highlight the intersection of various etiological agents capable of eliciting clinical manifestations that mirror child neglect. Case studies further illustrate how recurrent infections by viral agents of encephalitis, layered over host genetics in the form of heterozygosity, can reveal a viral-induced haploinsufficiency condition that is easily conflated with child neglect. To help prevent such conflations in the future, we systematically analyzed over 1.1 million alleles across ~2,300 genetic loci that are at greatest risk for child neglect conflation cases. Our analytical pipeline, comprising multivariate statistical analyses and Topological Data Analysis (TDA), highlights each of 1.1 million allelic contributions towards child neglect conflation. We advise that future child neglect cases involve establishing the absence of recurrent viral agents of encephalitis as well as ensuring the absence of any null mutation at each of the ~2,300 genetic loci at greatest risk for child neglect conflation. Caution should thus be exercised when approaching child neglect cases involving heterozygosity at any of these genetic loci, especially when host immunological evidence suggestive of recurrent viral infections is present in the pediatric setting.
