Microbial Beta Glucosidase Enzymes: Recent Advances in Biomass Conversation for Biofuels Application.

The biomass to biofuels production process is green, sustainable, and an advanced technique to resolve the current environmental issues generated from fossil fuels. The production of biofuels from biomass is an enzyme mediated process, wherein β-glucosidase (BGL) enzymes play a key role in biomass hydrolysis by producing monomeric sugars from cellulose-based oligosaccharides. However, the production and availability of these enzymes realize their major role to increase the overall production cost of biomass to biofuels production technology.

The impact of maternal separation and isolation stress during stress hyporesponsive period on fear retention and extinction recall memory from 5-week- to 1-year-old rats.

The purpose of the present study was to determine whether age would disrupt fear retention and extinction memory in rats pre-exposed to maternal separation and isolation stress; these rats are called MS rats. MS stress was induced by exposing rat pups into maternal separation followed by isolation stress from peer groups (MS) daily/6 h during stress hyporesponsive period, while controls rats that were undisturbed during this period are called NMS rats. 5, 8, 15 and 52 weeks later, these animals were exposed to classical fear conditioning test by pairing auditory stimulus (conditioned stimulus, CS+) with electric footshock.

Severe cytomegalovirus infections in immunocompetent patients at admission as dengue mimic: successful treatment with intravenous ganciclovir.

Cytomegalovirus (CMV) infection is associated with adverse clinical outcomes in immunosuppressed persons. The incidence and association of CMV reactivation with adverse clinical outcomes in critically ill persons lacking evidence of immunosuppression at ICU admission has received great attention in the practice of critical care medicine. Critically ill patients in ICU who had associated risk factors such as mechanical ventilation, severe sepsis, or blood transfusion are more prone to CMV activation, which in turn led to increased mortality and morbidity in terms of increased ICU stay, longer duration of mechanical ventilation, and higher rates of nosocomial infections.

I32E and V36K double mutation in beta2-sheet abrogates amyloid beta peptide toxicity.

Alzheimer's disease (AD) is the most common cause of dementia in the elderly, wherein, the accumulation of amyloid beta (Abeta) peptide as cytotoxic oligomers leads to neuropathologic changes. Transgenic mice with brain Abeta plaques immunized with aggregated Abeta have reduced amyloid burden and improved cognitive functions. However, such active immunization in humans led to a small but significant occurrence of meningoencephalitis in 6% AD volunteers due to Abeta induced toxicity.
