...easurements to study the postnatal development of Yangtze voleMicrotus fortis calamorum from birth through approximately 3 months of age with respect to growth. Vole pups were randomized into litters of 1-2 (LD, low density), 3-5 (MD, medium density), and 6-9 (HD, high density) individuals, and the body weight, body length, tail length, and hind foot length were measured and curve-fitted by using Von Bertalanffy and Logistic equations. Instantane...

Control rats were given normal saline while experimental rats were given T3 at a dose of 1mg/kg body weight. All the animals were sacrificed on 15th day. Weight of each rat was calculated at the time of T3 administration. Body weight of experiment...

...develop during fetal and postnatal periods through several distinct phases and they release their matured ova upon puberty. Oocytes surrounded by a single layer of pregranulosa follicular cells are called primordial follicles and they remain dormant in the meiotic prophase I stage. Activation of primordial follicles initiate through pregranulosa follicular cells. The primordial follicle takes several months to grow and develop to preovulatory follicles in mamm...

... phases during fetal and postnatal periods and they release their matured ova upon puberty. A finite number of primordial follicles form in the fetal ovary from primordial germ cells (PG) during the first stage of fetal development. The primordial follicles consist of oocytes surrounded by a single layer of pregranulosa follicular cells and they remain dormant in the meiotic prophase I stage. Primordial pregranulosa follicular cells initiate activation of prim...

In the current study, the mRNA levels of nephron genes were analyzed by reverse transcriptase PCR in neonatal and adult rat kidney tissues. These genes were divided into three categories. Group 1: renal multipotent progenitor genes; Group 2: self-renewal and pluripotency genes; Group 3 pluripotent state regulator genes. In neonates, renal progenitor genes Wt1, Pax2, Cad6, Si...

The rats of both genders were then tested in the open field and the elevated plus-maze tests for anxiety, and in the forced swimming test for depression at different time points. Additionally, we removed the PFC for biochemical analysis, specifically measuring nitric oxide and lipid peroxidation. The results indicate that, in both genders, MD generates an anxiogenic and depressive effect compared to the co...

This period is usually associated with the development of age-related neurodevelopmental processes. Nitric oxide (NO) is an essential signaling molecules that play an important role in physiological processes including neu...

For this purpose, pregnant guinea pigs in good health condition were obtained from public markets and housed in the animal facility until delivery to obtain neonate guinea pigs. Ten pups were separated from their mothers on the second day of their lives and euthanized using an overdose of ketamine HCl (85-95 mg/kg BW). The topographic position of organs was observed in situ, and samples we...

The second cohort consisted of 20 rats, with equal gender distribution, divided into PBS- and LPS-injected groups. At PND60, these rats underwent behavioral tests (Open Field, Elevated Plus Maze, and Forced Swim), followed by biochemical analysis of brain structures. The findings showed a prolonged elevation of NO following the early immune challenge with LP...
