Nitric oxide (NO), an endogenous signaling molecule, is involved in various physiological processes and stress responses in plants. In the present research, Pyrodwarf pear (Pyrus communis) rootstocks were grown by nutrient solution to investigate the effects of sodium nitroprusside (SNP) application as an NO donor at 0, 0.1, 0.5, and 1 mM levels on plant stress tolerance, content of ma...

background: the preparation of endometrium for embryo reception and implantation are controlled by ovarian hormones. these hormones have distinct cyclical changes during estrus cycle. objective: the aim of this study was to evaluate the changes in morphology and morphometrical indices of endometrium by daily injections of estrogen and progesterone in ovariectomized mouse. materials and methods:...

Background: Spinal cord injury (SCI) is a traumatic or nontraumatic injury that can leads to loss of functions such as feeling or mobility along with permanent and debilitating influences on the patient’s quality of life. Patients with SCI have weakened sexual function and a distinctive sperm profile described by normal to high sperm concentrations and unusually low sperm mobility. The reason o...

BACKGROUND Physician-induced demand (PID) is an important theory to test given the longstanding controversy surrounding it. Empirical health economists have been challenged to find natural experiments to test the theory because PID is tantamount to strong income effects. The data requirements are both a strong exogenous change in income and two types of treatment that are substitutes but have d...
