Integrins are transmembrane receptors that play a crucial role in cell adhesion and signaling by connecting the extracellular environment to the intracellular cytoskeleton. After binding with specific ligands in the extracellular matrix (ECM), integrins undergo conformational changes that transmit signals across the cell membrane. The integrin-mediated bidirectional signaling triggers various cellular responses, such as changes in cell shape, migration and proliferation.

The knowledge, attitude, and practices (KAP) of mothers and frontline health workers (FLWs) regarding optimal Infant and Young Child Feeding (IYCF) are essential for mitigating undernutrition and associated morbidities among under-five children. The study assessed the KAP of mothers (of children aged 0-60 months) and FLWs regarding recommended IYCF practices, the association of mother's KAP with their demographic characteristics and children's nutritional outcomes, and the prevalence of stunting, wasting, and underweight among children aged 0-60 months in five high-focus districts of Assam. Data were collected from 389 mothers, 456 children, and 138 FLWs using a standard method.

Article Synopsis
  • The study focused on the sudden deaths of 30 cervid animals in Assam's State Zoo, linked to peste des petits ruminants (PPR) virus.
  • The affected animals exhibited minimal clinical signs, but necropsy indicated a strong presence of PPRV, confirmed through RT-PCR testing.
  • The research identified domestic goats as potential carriers of PPRV, as tissue samples from them also tested positive, highlighting the risk of virus transmission to endangered species in captivity.

Unlabelled: Prostate cancer is the World's second most frequent malignancy, with the fifth-highest male mortality rate. In advanced prostate cancer patients, point mutations such as T877A and W741L are prevalent, imparting treatment resistance and hence promoting cancer development. The emergence of drug resistance in prostate cancer necessitates the development of suitable ligands to allow for stronger interactions with the receptors, which can inhibit cancer progression.

Selectable marker genes are useful for recognizing which cells have integrated specific sequences in their genome after genetic transformation processes. They are especially important for fruit trees genetic transformation to individuate putatively genetically modified events, because most of the protocols used to genetic engineer these species are often unsuccessful or with low efficiency. Traditional selectable marker genes, mainly of bacterial origin, confer antibiotics/herbicides-resistance or metabolic advantages to transformed cells.
