The ability to study bacteria at the single cell level has advanced our insights into microbial physiology and genetics in ways not attainable by studying large populations using more traditional culturing methods. To improve methods to characterize bacteria at the cellular level, we developed a new microfluidic platform that enables cells to be exposed to metabolites in a gradient of concentrations. By designing low-cost, three-dimensional devices with adhesive tapes and tailoring them for bact...

A hallmark of bacterial populations cultured in vitro is their homogeneity of growth, where the majority of cells display identical growth rate, cell size and content. Recent insights, however, have revealed that even cells growing in exponential growth phase can be heterogeneous with respect to variables typically used to measure cell growth. Bacterial heterogeneity has important implications for how bacteria respond to environmental stresses, such as antibiotics. The phenomenon of antimicrobia...

Population-scale and rapid testing for SARS-CoV-2 continues to be a priority for several parts of the world. We revisit the in vitro technology platforms for COVID-19 testing and diagnostics—molecular tests and rapid antigen tests, serology or antibody tests, and tests for the management of COVID-19 patients. Within each category of tests, we review the commercialized testing platforms, their analyzing systems, specimen collection protocols, testing methodologies, supply chain logistics, and rel...

The existence of dextran in sugar cane juice is a major problem in the sugar industry, causing substantial losses. Treatment of dextran through enzymatic hydrolysis using dextranase is highly recommended as the most suitable method at this time because this is more e？ective and more economical. This study investigated the production and characterization of dextranase from local isolate yeast to degrade dextran on sugar cane juice. The selected yeast was identifed on the basis of molecular identi...

Profession Education subject has wide coverage lecture material and tend to be regarded as a theoretical matter. Profession Education conventionally, students will only examine theoretically and less meets the subject goals. Evaluation shows that it needs improvement efforts from material aspects, strategies, and assessment systems in Profession Education lectures. The study focused on the description of the implementation and effect of GI in Professions Education subject, a description of EOOAT...

ABSTRACT Background: Incidences of sudden deaths (SD) are increasing day by day, especially in younger people. During routine practice, forensic persons have to deal not only criminal, accidental and suicidal deaths, but a large amount of cases of sudden deaths also. Most of the sudden deaths of younger victims are unexpected, clinically unexplained or otherwise obscure. Aims & Objectives: The present study was undertaken to know the major contributory causes of death in young victims of sudde...
