Background: Medial prefrontal cortex (mPFC) is considered to be involved in human cognition mPFCin terms of learning and memory. Hypoxia one the crucial factors causing secondary damage incerebral hemorrhage traumatic brain injury. However, underlying mechanisms possibletherapeutic approach prevent neuronal has not been attempted yet. Therefore, present studyaimed investigate role Tualang honey...
Prenatal stress is associated with an increased vulnerability to neurodevelopmental disorders, including autism and schizophrenia. To determine the critical time window when fetal antecedents may induce a disease predisposition, we examined behavioral responses in offspring exposed to stress during early, mid, and late gestation. We found that male offspring exposed to stress early in gestation...
Chronic perinatal intermittent hypoxia (IH) could have long-term cardiovascular effects by altering baroreflex function. To examine this hypothesis, we exposed rats (n = 6/group) for postnatal days 1-30 or prenatal embryonic days 5-21 to IH (8% ambient O2 for 90 s after 90 s of 21% of O2, 12 h/day) or to normoxia (control). Baroreflex sensitivity (BRS) and cardiac chronotropic responses were ex...
Regions of reduced oxygenation (hypoxia) are a characteristic feature virtually all animal and human solid tumours. Numerous preclinical studies, both in vitro vivo, have shown that decreasing oxygen concentration induces resistance to radiation. Importantly, hypoxia tumours is negative indicator radiotherapy outcome. Hypoxia also contributes other cancer therapeutics, including immunotherapy, ...
Infants who suffer perinatal brain injury, including those with encephalopathy of prematurity, are prone to chronic neurological deficits, including epilepsy, cognitive impairment, and behavioral problems, such as anxiety, inattention, and poor social interaction. These deficits, especially in combination, pose the greatest hindrance to these children becoming independent adults. Cerebral funct...
The aim of the present research was to investigate the impact of abnormal fetal environment on explicit memory performance. Based on animal models, it was hypothesized that infants of diabetic mothers (IDMs) experience perturbations in memory performance due to exposure to multiple neurologic risk factors including: chronic hypoxia, hyperglycemia/reactive hypoglycemia, and iron deficiency. Memo...

this experiment was conducted to evaluate the effects of supplemental l-arginine (arg) in reduced-protein diets on cardiopulmonary performance and intestinal morphology in the broilers reared at high altitude. a total of 156 day-old male broilers were randomly assigned to 3 treatments and 4 replicates of 13 chicks and reared up to 42 days of age. treatment groups were designed as a normal-prote...
Background and Objective: Ghrelin has different functions in the body and one of its newly known roles is the antiapoptotic effect. However, this effect of ghrelin has not been considered in the probable hypoxia induced apoptosis in the animal lung tissue. The aim of this study was to examine the effect of ghrelin treatment on Bax/Bcl-2 gene expression in the lung tissue of rats with chronic hy...
Objective(s): The aim of this study is to explore the potential neuroprotective effects of Ginkgolide B (GB), a main terpene lactone and active component in Ginkgo biloba, in hypoxia-induced neuronal damage, and to further investigate its possible mechanisms.Materials and Methods: 54 Sprague-Dawley rats were randomly divided into three groups: the untreated control group (n=18); the hypoxia gro...
