This in vitro study evaluated the detrimental effect of acute gamma (γ)-irradiation on rat immature hippocampal neurons. Rat immature hippocampal neurons (0.5 day in vitro) were irradiated with 0~4 Gy γ-rays. Cytotoxicity was analyzed using a lactate dehydrogenase release assay at 24 h after γ-irradiation. Radiation-induced cytotoxicity in immature hippocampal neurons increased in a dose-depend...

Rising feed costs and recurring feed shortages necessitate the investigation into alternative and underutilized feed resources. Nutritional characteristics of species are either unknown or limited to leaves and ground material from small stems. Therefore, the objective was to quantify nutritional characteristics, 48-h true IVDMD (tIVDMD), microbial gas production, and secondary compound charact...

Low levels of IFN-gamma secreted by immature B cells prevent their own migration and homing to the lymph nodes and premature encounter with Ag. In this study we followed the mechanism regulating IFN-gamma secretion by immature B cells. We show that the MHC class I receptor, Ly49D, is expressed on immature B cells and is down-regulated during maturation. Activation of this receptor leads to incr...

The effect of dehydroepiandrosterone (DHEA) on the activity and isoenzyme patterns of liver glucose 6- phosphate dehydrogenase (G6PD) was investigated in rats during different stages of growth. G6PD activity of mature rats was less than those of the immature (43%) and newborn (35%) animals. DHEA at 10 M) inhibited G6PD activity of the mature , immature and newborn rats by 79%, 39% , and 88%...

Gliomatosis peritonei is a rare entity associated with ovarian teratoma, both mature and immature. We present case of 24-year-old female diagnosed immature grade 2 on histopathological examination. The presence glial tissue the omentum established diagnosis gliomatosis peritonei. It harmless condition favorable prognosis. However, regular follow-up required as it risk recurrence malignant trans...

Suppression of depolarizing postsynaptic potentials and isolated GABA-A receptor-mediated fast inhibitory postsynaptic potentials by the muscarinic acetylcholine receptor agonist, oxotremorine-M (10 microM), was investigated in adult and immature (P14-P30) rat piriform cortical (PC) slices using intracellular recording. Depolarizing postsynaptic potentials evoked by layers II-III stimulation un...

A prerequisite for most plant transformation systems is an efficient and reliable method to regenerate phenotypically normal plants. The present studies were undertaken with a view to the effects of Benzyl amino purine (BAP) and Indol butyric acid (IBA) hormones and genotypes on in vitro germination of immature embryos in walnut (Juglans regia L.). The immature embryos of walnut were excised fr...

A large population of immature neurons is present in the ventromedial portion of the adult primate amygdala, a region that receives substantial direct projections from the hippocampal formation. Here, we show the effects of neonatal (n = 8) and adult (n = 6) hippocampal lesions on the populations of mature and immature neurons in the paralaminar, lateral, and basal nuclei of the adult monkey am...

Our understanding regarding the function of YjeQ (also called RsgA), RbfA, RimM and Era in ribosome biogenesis has been derived in part from the study of immature 30S particles that accumulate in null strains lacking one of these factors. However, their mechanistic details are still unknown. Here, we demonstrate that these immature particles are not dead-end products of assembly, but progress i...
