Nanoparticle-Doped Antibacterial and Antifungal Coatings.

Antimicrobial polymeric coatings rely not only on their surface functionalities but also on nanoparticles (NPs). Antimicrobial coatings gain their properties from the addition of NPs into a polymeric matrix. NPs that have been used include metal-based NPs, metal oxide NPs, carbon-based nanomaterials, and organic NPs.

Polymer Coated Functional Catalysts for Industrial Applications.

Surface engineering of conventional catalysts using polymeric coating has been extensively explored for producing hybrid catalytic material with enhanced activity, high mechanical and thermal stability, enhanced productivity, and selectivity of the desired product. The present review discusses in detail the state-of-the-art knowledge on surface modification of catalysts, namely photocatalysts, electrocatalysts, catalysts for photoelectrochemical reactions, and catalysts for other types of reactions, such as hydrodesulfurization, carbon dioxide cycloaddition, and noble metal-catalyzed oxidation/reduction reactions. The various techniques employed for the polymer coating of catalysts are discussed and the role of polymers in enhancing the catalytic activity is critically analyzed.

The past and present of Drosophila models of traumatic brain injury.

Traumatic brain injuries are highly recognized as one of the leading causes of mortality and morbidity worldwide. A chronic and debilitating condition by nature, TBI is reportedly affecting the socio-economic well-being of society due to the unavailability of effective prophylaxis. Moreover, TBI is responsible for a myriad of systemic complications such as neurological deficits, gastrointestinal dysfunction, visual impairment, and disturbed circadian rhythm, to name a few.

Towards a Mathematical Model for the Viral Progression in the Pharynx.

In this work, a comprehensive model for the viral progression in the pharynx has been developed. This one-dimension model considers both Fickian diffusion and convective flow coupled with chemical reactions, such as virus population growth, infected and uninfected cell accumulation as well as virus clearance. The effect of a sterilizing agent such as an alcoholic solution on the viral progression in the pharynx was taken into account and a parametric analysis for the effect of kinetic rate parameters on virus propagation was made.

Seroprevalence of brucellosis in man.

A total of 352 human serum samples were screened for brucellosis. A combination of serological tests including Rose Bengal plate test (RBPT), standard tube agglutination test (STAT) and dot-enzyme linked immunosorbent assay (dot-ELISA) were employed for the purpose. The study revealed a prevalence rate of 4.

Human brucellosis: review of an under-diagnosed animal transmitted disease.

Human brucellosis is an important animal transmitted disease of man. Although, the cases have been recorded all over the world, the prevalence is higher in developing countries. Lack of sufficient knowledge about the disease among the physicians, its under-diagnosis or misdiagnosis and absence of effective prevention and management strategies are attributed to the widespread of the disease.

Enterotoxigenicity as an attribute of virulence in Yersinia enterocolitica.

Seven strains of Y. enterocolitica were screened for their enterotoxic activity. Three strains belonging to serogroups 0:3 and 0:9 elicited enterotoxic response in rabbit ligated gut segments and in infant mice.

Partial purification and characterization of Salmonella cytotoxin.

The cytotoxins of two strains of Salmonella enterica subspecies enterica serovar Nchanga (MP2309) and Virchow (MP1871) were partially purified and characterized physicochemically. The toxin was salt-precipitable and non-dialysable. Upon filtration through Sephadex G-100 gel column, the toxicity was observed mainly in 2nd peak.

Tissue changes induced by enterotoxic preparations of Salmonella weltevreden in ligated rabbit gut segments.

Culture filtrates and cell lysates of two strains of S. weltevreden which caused dilation of ligated rabbit gut segments (characteristic associated with the enterotoxic activity) induced mild to severe architectural changes in the test segments of intestine. The dilated segments contained thick, bloody and mucoid exudates.

A delayed permeability factor in the culture filtrates and cell lysates of Salmonella weltevreden.

Salmonella weltevreden strains produced a delayed permeability factor (PF) when tested on depilated rabbit skin. The PF activity could be demonstrated in freshly concentrated culture filtrates as well as in the cell lysates. The activity varied with strain and preparation.
