Percutaneous penetration of chemicals from clothing can result in both acute and chronic toxicities. Although personal protective equipment composed of nonwoven material can provide thorough protection, it is often uncomfortable under normal occupational conditions. Certain everyday textiles are often utilized as protective clothing due to their cost, comfort, and convenience. Although common textiles may cover most skin, certain regions remain exposed by such outfits.

A cluster of pneumonia cases of unknown etiology associated with pyrexia and acute respiratory distress was identified in Southern China. Links between the previous severe acute respiratory syndrome (SARS) cases and the region’s seafood market were noted with the possibility of a new zoonosis and SARS-CoV-2 was identified as the responsible agent.

In present study kinetic, thermal and rheological characteristics of oil isolated from flaxseed were studied and because of high content of α-linolenic acid (essential omega-3 fatty acid), flaxseed oil was incorporated in muffins by replacing fat/shortening at different levels (10%, 20%, 30% and 40%).

L. monocytogenes continues to be a major health issue in Europe, as well as worldwide. Faster methods, not only for detection, but also for sample preparation are of great interest particularly for this slow-growing pathogen. Immunomagnetic separation has been previously reported to be an effective way to concentrate bacteria, and remove inhibitors.

The objective of this research is to avail an optimum cold plasma generating device for inactivating Aspergillus flavus from nuts surface. For this purpose, a variety of tests were carried out using three applicable plasma generating devices such as atmospheric pressure capacitive coupled plasma (AP-CCP), direct current diode plasma (DC-DP), and inductively coupled plasma (ICP) for different values of input power, pressure, and irradiation time, using Argon gas.

Botulinum neurotoxin serotype E (BoNT/E) is one of the major causes of human botulism, which is a life-threatening disease caused by flaccid paralysis of muscles. After receptor-mediated toxin internalization into motor neurons, the translocation domain (HN) of BoNT/E transforms into a protein channel upon vesicle acidification in endosomes and delivers its protease domain (LC) across membrane to enter the neuronal cytosol.

A facile method was introduced for preparing a biocharcoal aerogel, which was derived from pomelo peel as the only raw material. The inner spongy layer of pomelo peel was freeze‐dried for maintaining three‐dimensional structure, further carbonized under high temperature and oxygen‐limited conditions. The morphological structure and graphitization degree of biocharcoal aerogel were characterized by scanning electron microscope and Raman spectrum.

This study describes the pathological changes, antibody response, isolation and distribution patterns following exposure of non‐pregnant goats to live B. melitensis. Eighteen healthy adult female goats were divided into 2 equal groups. Group 1 was infected via conjunctival sac with 109 cfu/mL of B. melitensis while Group 2 was similarly exposed to sterile PBS. Serum and swabs from the eyes and vagina were collected at 5‐day intervals.

Fungi have been proved as promising and prolific sources of functional secondary metabolites with potent agricultural applications. In this study, 14 xanthone derivatives (1–14), including six new ones, versicones I–N (1–4, 7, 11), and a biogenetically related derivative (15), were isolated from the alga-derived fungus Aspergillus versicolor D5. Their structures were elucidated by comprehensive spectroscopic methods.

Beauvericin (BEA) is a member of the enniatin family of mycotoxins which has received increasing interest because of frequent occurrence in food and feed. By its ionophoric properties, BEA is able to alter membrane ion permeability uncoupling oxidative phosphorylation. It was also shown to alter oocyte mitochondrial function.

ABSTRACT The infection of fruits by Penicillium expansum (P. expansum) do not only cause economic loss but also potentially endanger human health, especially because few biocontrol agents against this fungus have been well studied yet. In this work, to verity the antifungal activity against P. expansum of 22 Bifidobacterium and 44 Lactobacillus, dual-culture overlay assay, microtiter plate well assay and agar spot assay were successively performed.

Salmonella Enteritidis is responsible for a significant proportion of foodborne Salmonellosis in the United States and continues to be attributable to table eggs, despite increased federal oversight in recent years. Technologies, including feed additives, continue to be evaluated for pre-harvest application of their potential food safety benefits.
