Role of growth temperature on microstructural and electronic properties of rapid thermally grown MoTethin film for infrared detection.

In the field of electronic and optoelectronic applications, two-dimensional materials are found to be promising candidates for futuristic devices. For the detection of infrared (IR) light, MoTepossesses an appropriate bandgap for which p-MoTe/n-Si heterojunctions are well suited for photodetectors. In this study, a rapid thermal technique is used to grow MoTethin films on silicon (Si) substrates.

A novel rspA gene regulates biofilm formation and virulence of Salmonella Typhimurium.

Salmonella spp. are facultative anaerobic, Gram-negative, rod-shaped bacteria and belongs to the Enterobacteriaceae family. Although much has been known about Salmonella pathogenesis, the functional characterizations of certain genes are yet to be explored.

Immune modulations and survival strategies of evolved hypervirulent Salmonella Typhimurium strains.

Background: Evolving multidrug-resistance and hypervirulence in Salmonella is due to multiple host-pathogen, and non-host environmental interactions. Previously we had studied Salmonella adaptation upon repeated exposure in different in-vitro and in-vivo environmental conditions. This study deals with the mechanistic basis of hypervirulence of the passaged hypervirulent Salmonella strains reported previously.

Stress-induced adaptations in Salmonella: A ground for shaping its pathogenesis.

Microorganisms are able to adapt to multiple adverse environmental conditions that facilitate their survival. These microorganisms including bacteria, viruses, algae, fungi, and protozoans are exposed to different abiotic and biotic challenges throughout their life. Adaptations help these organisms to overcome the challenges and evolve as successful pathogens which at the same time might lead to severe disease outcome.

Repeated in-vitro and in-vivo exposure leads to genetic alteration, adaptations, and hypervirulence in Salmonella.

Adaptation is an important phenomenon for the survival of any organism in various in-vitro and in-vivo conditions leading to their better survival. We studied Salmonella, for the evolutionary adaptation under different conditions. When Salmonella was passaged for 12 rounds in Luria Bertani (P12-STM) media, F media (F12-STM) and Caenorhabditis elegans (Ce12-STM), we found certain phenotypic variations with respect to unpassaged strain.
