BACKGROUND Memantine attenuates heart stress due cold stress, however, no study focused its effects on liver and adrenal gland. We evaluated its effects on lipid depletion in adrenal gland and glycogen depletion in liver of rats exposed to cold stress. METHODS Male rats divided into 4 groups: 1)Control (CON); 2)Memantine (MEM); 3)Induced cold stress (IH) and; 4)Induced cold stress memantine (...

background & aim: glycyrrhiza l. (fabaceae) consists of perennial herbs grow in sandy soils with hard lightness. three species of the genus grow in iran, among them g. glabra l. has the widest distribution. it is well known in english as licorice and the root extract includes flavonoids and glycyrrhizin are used widely in medicine, food industry, tobacco products and other industries. liqui...

in this study, accumulation of h2o2, malondialdehyde (mda) (as cold-induced oxidative stress indicators), the transcript levels of dehydrin and beta-glucosidase genes (involved in metabolic responses) was evaluated in chickpea cv. jam, using qrt-pcr during control, cold acclimation (ca), cold stress (cs), recovery, and freezing phases. results showed the existence of wide range of genetic capac...

Cold stress affects rice growth, quality and yield. The investigation of genome-wide gene expression is important for understanding cold stress tolerance in rice. We performed comparative transcriptome analysis of the shoots and roots of 2 rice seedlings (TNG67, cold-tolerant; and TCN1, cold-sensitive) in response to low temperatures and restoration of normal temperatures following cold exposur...

Previous reports about the rat ovary have shown that cold stress promotes ovarian morphological alterations related to a polycystic ovary (PCO) condition through activation of the ovarian sympathetic nerves. Because the noradrenergic nucleus locus coeruleus (LC) is activated by cold stress and synaptically connected to the preganglionic cell bodies of the ovarian sympathetic pathway, this study...

Stress is one of the basic factors in the etiology of number of diseases. Cold-stress occurs when the surrounding temperature drops below 18 degrees C, the body may not be able to warm itself, and hence serious cold-related illnesses, permanent tissue damage and death may results. The present study was aimed to investigate the effect of Triphala (Terminalia chebula, Terminalia belerica and Embl...

fennel (foeniculum vulgare mill.) is widely cultivated for its edible, strongly-flavored leaves, fruits, seeds andmedicinal uses. as the wild and cultivated plants are influenced by environmental stresses, the effects of salt (25, 50 and 75 mm nacl), nitrogen and iron deficiency (0 n, 0.5 n of hoagland’s solution, 0 fe and 0.5 fe ofhoagland’s solution), 2°c cold (2, 3 and 4 h) and drought (3, 5...

exposure to cold work environment is an occupational health hazard and poses adverse effect on workers health, performance and productivity. this study was performed in a cold food-storage warehouse complex in tehran-iran in order to evaluate the workers' exposure to cold stress. twenty nine exposed workers and 33 non-exposed workers as control subject were included in this study. climatic fact...

Temperature and other environmental stressors are known to affect blood pressure and heart rate. In this activity, students perform the cold pressor test, demonstrating increased blood pressure during a 1- to 2-min immersion of one hand in ice water. The cold pressor test is used clinically to evaluate autonomic and left ventricular function. This activity is easily adapted to an inquiry format...
