background: evidences show that aloe vera (a. vera), camellia sinensis, hibiscus sabdariffa and sophora alopecuroides may prevent gastric ulcer induced by non-steroidal anti-inflammatory drugs (nsaids). objective: to examine the protective potential of these plants against indomethacin-induced gastric ulcer in the rat. methods: saline, a. vera leaf gel powder and 70% alcoholic extracts of the o...

Human physiological signals have been widely used to non‐invasively measure cognitive load (CL) during task execution. A major challenge for CL detection is the presence of stress, which may affect physiological measurements in ways that confound reliable detection of CL. In this experiment we investigated the effect of stress on cognitive load measurement using galvanic skin response (GSR) as ...

to study the effect of salinity on physiological and morphological traits of chickpea in 2010 at faculty of agriculture and natural resources, university of tehran with seven chickpea genotypes. two experiments design was rcbd with 3 replications and 5 levels of salinity stress (ctrl, 200, 150, 100, 50 mm) for laboratory experiment on germination indices and greenhouse experiment on physiologic...

The behavioral approach (BAS) and behavioral inhibition (BIS) systems are central to theories of both personality and psychopathology, yet agreement on methods of assessing BAS and BIS sensitivity has yet to emerge. We compare the Carver and White (1994) BIS/BAS scales with putative physiological markers of BAS (pre-ejection period [PEP], respiratory sinus arrhythmia [RSA]) and BIS (electroderm...

BACKGROUND In patients with bronchial obstruction, pulmonary function tests may not change significantly after intervention. The airflow asynchrony in both lungs due to unilateral bronchial obstruction may be applicable as a physiological indicator. The airflow asynchrony is reflected by the difference in the left and right lung sound development at tidal breathing. OBJECTIVES To investigate ...

in order to investigate effective morpho-physiological traits related to salinity resistance, and their relationship with grain yield as well as study of salinity tolerance and susceptibility indices in 169 barley recombinant inbred lines, a  population of barley derived from a cross between arigashar and igri, this experiments were carried out using alpha lattice design with two replications d...

Selection of genotypes based on high value of heritability and forecasted genetic conditions would be an effective method for improvement of wheat cultivars. The present investigation was carried out to estimate the genetic variability of agro-physiological characters using biometrical genetic techniques in 20 bread wheat genotypes under irrigated condition. For this purpose an experiment was c...

If you want to learn about the physiology of the cardiovascular system, and learn it really well, you will want to use this book. In its seventh edition, this book is a clear, understandable treatment of a potentially overwhelming topic. Throughout, the book maintains its focus on fundamental concepts and never loses the reader in esoterica (if a formula is derived it is usually highlighted in ...
