objective: walnut (juglans regia) is a domestic fruit of iran. walnut kernel (wk) has many beneficial constituents such as unsaturated fatty acids, antioxidants, and vitamin e. scientific studies have shown that fatty acids and vitamin e can modulate learning and memory processes. the aim of the present work was to study effects of walnut consumption by mothers during pregnancy and lactation on...

neuroinflamation occurring after traumatic brain injury (tbi) is a complex phenomenon comprising distinct cellular and molecular events involving the injured cerebral tissue. mechanical injury to adult rat brain elucidated the accumulation in the affected area of trophic activity. in the tissue adjacent to the injury, trophic titers began to rise after the lesion. this study aimed to determine ...

Results of neural grafting to excitotoxic and ischemic lesions of the adult rat hippocampus is reviewed with particular emphasis on the exchange of host-transplant nerve connections. Based on observations obtained by a variety of tracing techniques about 6 weeks after--(i) grafting of pieces of neonatal fascia dentata to one week old ibotenic acid lesions of the adult rat fascia dentata, (ii) g...

Heated debate has surrounded the issue of whether adult stem cells can differentiate into cardiac myocytes and contribute to the function of the heart. In this issue of Cell, demonstrate stem cells in the adult rat heart that differentiate into cardiac myocytes in vitro and, when injected into the adult rat heart, can reconstitute the injured myocardium and improve function. These findings shou...

Pigmentation defects are common in the inherited disease type 1 neurofibromatosis (NFl), predicting a role for the NFl gene product, neurofibromin, in the skin. We used immunohistochemistry to determine the distribution of neurofibromin in normal developing and adult rat skin, normal neonatal and adult human skin, and skin from patients affected with NFL The distribution of NFl mRNA in the epid...

Myosin isoenzyme profiles of rat and chicken embryonic cardiac myocytes were studied during differentiation and growth in vitro by native-gel electrophoresis and assay of Ca2+-activated ATPase. The electrophoretic pattern of myosin extracted from 18-day-embryonic-rat myocytes after 7 days in culture exhibits three isoenzyme bands, V1, V2 and V3, of which the slow-migrating V3 is predominant. Th...

This study was designed to compare the activities of sarcoplasmic (SR) Ca2+-ATPase and Ca2+ uptake in fish and mammalian hearts and to determine whether thermal acclimation has any effect on the function of the cardiac SR in fish. To this end, we measured thapsigargin-sensitive Ca2+-ATPase activity and thapsigargin-inhibitable Ca2+ uptake velocity in crude cardiac homogenates of newborn and adu...

The tachykinins, including their major representative substance P (SP), are an essential component of its non-adrenergic, non-cholinergic transmission the myenteric plexus enteric nervous system. Hence, understanding role that SP plays in conduction a wide variety motility and secretory reflexes lies evidence-based sites expression. In present study, presence, distribution staining intensity SP...

Erectile dysfunction is a major public health problem leading to harmful consequences for couples. Hence the need find adequate treatments using medicinal plants such as Pycnanthus angolensis, Cameroonian plant used treat erectile dysfunction. The effects of aqueous extract angolensis wood were evaluated on male rat sexual behavior and nitric oxide release. Adult Wistar rats divided into 4 grou...
