Perceptual learning deficits mediated by somatostatin releasing inhibitory interneurons of olfactory bulb in an early life stress mouse model.

Early life adversity (ELA) causes aberrant functioning of neural circuits affecting the health of an individual. While ELA-induced behavioural disorders resulting from sensory and cognitive disabilities can be assessed clinically, the neural mechanisms need to be probed using animal models by employing multi-pronged experimental approaches. As ELA can alter sensory perception, we investigated the effect of early weaning on murine olfaction.

Differential expression of CRAC channel in alloxan induced Diabetic BALB/c mice.

CRAC (Calcium Release Activated Calcium) channel is one of the most important channels regulating calcium influx and has been involved in many autoimmune diseases. The contribution of CRAC channel in the pathogenesis of Type 1 Diabetes (T1D) has not been described much. Thus, we aimed to study the expression of CRAC channel and inflammatory cytokines like IL-1β (Interleukin -1β) and TNF-α (Tumor Necrosis Factor-α) in the spleen-derived cytotoxic T cells, Bone marrow monocytes (BMM) and macrophages differentiated from BMM in the alloxan induced T1D mice.

A comparison of aquaporin function in mediating stomatal aperture gating among drought-tolerant and sensitive varieties of rice (Oryza sativa L.).

Climate change drastically affects the cultivation of rice, and its production is affected significantly by water stress. Adaptation of a plant to water deficit conditions is orchestrated by efficient water uptake and a stringently regulated water loss. Transpiration remains the major means of water loss from plants and is mediated by microscopic pores called stomata.

Understanding autoimmunity: The ion channel perspective.

Ion channels are integral membrane proteins that orchestrate the passage of ions across the cell membrane and thus regulate various key physiological processes of the living system. The stringently regulated expression and function of these channels hold a pivotal role in the development and execution of various cellular functions. Malfunction of these channels results in debilitating diseases collectively termed channelopathies.

Suppression of different classes of somatic mutations in Arabidopsis by vir gene-expressing Agrobacterium strains.

Background: Agrobacterium infection, which is widely used to generate transgenic plants, is often accompanied by T-DNA-linked mutations and transpositions in flowering plants. It is not known if Agrobacterium infection also affects the rates of point mutations, somatic homologous recombinations (SHR) and frame-shift mutations (FSM). We examined the effects of Agrobacterium infection on five types of somatic mutations using a set of mutation detector lines of Arabidopsis thaliana.

Parental age affects somatic mutation rates in the progeny of flowering plants.

In humans, it is well known that the parental reproductive age has a strong influence on mutations transmitted to their progeny. Meiotic nondisjunction is known to increase in older mothers, and base substitutions tend to go up with paternal reproductive age. Hence, it is clear that the germinal mutation rates are a function of both maternal and paternal ages in humans.
