In this experiment, wheat plants were exposed to drought stress during seed development then we worked on the obtained seeds. The seed mitochondrial ultra-structure, and antioxidant enzymes in seedling were investigated after exposure to seed accelerated ageing. Drought stress during seed development induced some changes in mitochondrial ultra-structure. Encountering seed development to drought...

background: aging has a growing trend in the world. the elderly experience a high incidence of hospitalization and coronary bypass surgery compared with other age groups, and pain is the most common complaint in these patients. this research was conducted to compare the effect of acupressure and cryotherapy on the pain of removing drain tube from the chest of the elderly who have undergone open...

due to their widespread availability, sandstones are commonly used as a natural stone for buildings, monuments and sculptures. in thecurrent study, nine sandstone samples from the upper red formation (specified by the letters a, b, c, cg, s, s1, sh, tr and min)were studied from a petrophysical point of view and their durability was evaluated. then, their suitability as building stones wasassess...

background sleep apnea (sa) is a common sleep disorder among us adults. associations of sa with alcohol consumption and some chronic diseases have been inconsistent. objectives this study aimed to estimate prevalence of sa and examine its associations with potential factors including alcohol consumption, asthma, diabetes, and hypertension. patients and methods this was a cross-sectional study o...

fifty-four specimens of the kingsoldier bream, argyrops spinifer (forsskal, 1775) from coastal waters of the persian gulf, in bushehr province, were aged by otolith readings to assess the suitability of using otolith length/weight for age estimation in this fish. otolith length and weight increased along with an increase in length and age of the fish. the relationship between fish length (tl) a...

we propose to use a mathematical method based on stochastic comparisons of markov chains in order to derive performance indice bounds‎. ‎the main goal of this paper is to investigate various monotonicity properties of a single server retrial queue with first-come-first-served (fcfs) orbit and general retrial times using the stochastic ordering techniques‎.

In 2004 and 2005, Johnson et al. published two very provocative studies (1, 2), in which they claimed that in the adult mouse ovary, neo-oogenesis takes place and originates either from the ovarian surface epithelium (OSE) (1) or from the bone marrow (BM) via circulating blood cells (2). These studies were provocative since they challenged the long-held view that mammals are born with a finite ...

In vitro fertilization (IVF) and other assisted reproductive technologies present an enormous hope to couples with fertility difficulties. Assisted reproductive technology is one of the risk factors that can result in anxiety in these couples. Indeed, IVF-treatments cause a stress, for both the woman and her partner. The different stages of the IVF-procedure can affect the emotional life of the...
