Abstract:
Gamma-Aminobutyric Acid (GABA) is a non-protein amino acid widely recognized for its beneficial effects on human health, including its roles in reducing anxiety, regulating blood pressure, and promoting neurological health. In this study, an attempt is made to produce GABA using plant-based substrates—specifically carrot (Daucus carota) and radish (Raphanus sativus)—through microbial fermentation involving lactic acid bacteria (LAB). The selection of these vegetables is based on their availability, nutritional value, and natural content of fermentable sugars, which are critical for

Compound 1 was synthesized by a symmetrical condensation reaction of 3,5-dihydroxybenzoic acid in concentrated sulfuric acid. Reduction of the carbonyl group in compound 1 with SnCl2/HCl-HOAc affords compound 2. Compound 3 was prepared by modifying the hydroxy groups of compound 2 by a methylation reaction.

Abstract Effective mosquito surveillance and management depend on a thorough understanding of the biology and feeding patterns unique to species and sex. Given that a propensity to sugar feed is necessary for some mosquito surveillance and newer control strategies, we sought to document the amount of total sugar in wild Aedes aegypti (L.) and Culex quinquefasciatus (Say) captured from five different locations in the Lower Rio Grande Valley (LRGV) of South Texas over 2 yr.

Abstract:
Abstract Established methods for quantitative analysis of fecal carbohydrates (CHO) are time consuming, require unpopular sample handling, and are therefore rarely performed. The aim of this study was to evaluate the efficiency, validity, and practicability of near-infrared reflectance analysis (NIRA), compared with standard methods for measurement of fecal CHO. Excretion of fecal CHO was cross- validated spectrophotometrically with the anthrone method. Fecal CHO concentrations ranged form 2.7 to 24.5 g/kg wet weight.

Abstract:
Quantification of carbohydrates by the anthrone method is a colourimetric assay. In this method, first, the complex carbohydrates are hydrolysed in a highly acidic medium, resulting in monosaccharides. Thereafter, these monosaccharides are dehydrated to form 5-hydroxymethylfurfural (5-HMF) or 2-furfural (2-F), followed by reacting with anthrone reagent. This reaction produces a blue-green complex which is colourimetrically determined.

The relationship among microbes, animals, and humans often manifests as zoonotic, anthropo-zoonotic, or sylvatic infections. Infections transmitted from animals to humans are considered zoonotic and often cause outbreaks of diseases, epidemics, or even pandemics. The battle for survival between microbes and mammalian species has been occurring throughout all documented human history. The control, de-escalation, or deceleration of the spread of these diseases often hinges upon the detection of infectious agents.
