Heterozygous Loss of Yap1 in Mice Causes Progressive Cataracts.

Purpose: Yap1 encodes an evolutionarily conserved transcriptional coactivator and functions as a down-stream effector of the Hippo signaling pathway that controls tissue size and cell growth. Yap1 contributes to lens epithelial development. However, the effect of Yap1 haplodeficiency on the lens epithelium and its role in the development of cataracts has not been reported.

TAM receptors support neural stem cell survival, proliferation and neuronal differentiation.

Tyro3, Axl and Mertk (TAM) receptor tyrosine kinases play multiple functional roles by either providing intrinsic trophic support for cell growth or regulating the expression of target genes that are important in the homeostatic regulation of immune responses. TAM receptors have been shown to regulate adult hippocampal neurogenesis by negatively regulation of glial cell activation in central nervous system (CNS). In the present study, we further demonstrated that all three TAM receptors were expressed by cultured primary neural stem cells (NSCs) and played a direct growth trophic role in NSCs proliferation, neuronal differentiation and survival.

First Report of Tobacco streak virus Infecting Kenaf (Hibiscus cannabinus) in India.

The natural occurrence of Tobacco streak virus (TSV) in Hibiscus cannabinus was detected by enzyme-linked immunosorbent assay using an antiserum raised against TSV and reverse transcription polymerase chain reaction (PCR) using primers specific for the coat protein gene of the virus. Sequence analysis of the PCR products showed 99.6 and 99.

Utility of multiplex reverse transcriptase-polymerase chain reaction for diagnosis and serotypic characterization of dengue and chikungunya viruses in clinical samples.

The reemergence of chikungunya virus (CHIKV) has compounded the already existing dengue problem because of clinical similarities and common vector, demanding the need for a rapid and specific diagnosis. Thus, dengue chikungunya multiplex reverse transcriptase-polymerase chain reaction (DCmRT-PCR) was developed and validated for simultaneous detection of dengue and chikungunya viral infections and its utility in virus serotyping. Blood samples from 97 suspected dengue and chikungunya cases and 10 healthy controls were subjected to dengue and chikungunya conventional RT-PCR and DCmRT-PCR.

Reemergence of Chikungunya virus in Indian Subcontinent.

Chikungunya virus (CHIKV), a reemerging arboviral disease of public health concern is characterized by a triad of fever, rash and arthralgia. It was responsible for a number of epidemics in Asia and Africa. The severity of the current epidemic can be judged by the fact that an estimated 1.
