nitric oxide (no) is a highly reactive signaling molecule and plays a variety of physiological roles in plants. the research on the application of no to postharvest preservation of flowers and fruits shows great promise in recent years. however, the physiological mechanism of exogenous no to affect cut flowers is not very clear, and no donor treatment protected plants from damage by increasing ...

Background & Aim: The world production and consumption of essential oils and perfumes are increasing very fast. Lippia citriodora H.B.K. is an herbal species mainly used as a spice and medicinal plant. Endogenous levels as well exogenous application of plant growth regulators (PGR) could affect essential oil production and chemical compositions. Experimental: To study the effect of ex...

Objective Spinal cord injury (SCI) causes infertility in male patients through erectile dysfunction, ejaculatory dysfunction, semen and hormone abnormalities. Oxidative stress (OS) is involved in poor semen quality and subsequent infertility in males with SCI. The aim of this study is to examine the effects of SCI on the level of testosterone hormone. MaterialsAndMethods In this experimental st...

Background : Lipoid pneumonia is a rare disease and usually reported as sporadic cases. Exogenous lipoid more common form of pneumonia. Untypical characteristics makes incidence rate this cases are often imprecise. The diagnosis made from history lipid containing material aspiration, radiologic imaging, histopathological examination. There no treatment choice because rarely made.
 Case Rep...

The anti-senescence biogenic polyamines (PAs) putrescine (Put), spermidine (Spd) and spermine (Spm) are involved in plant growth processes and responses to stress. The physiological mechanism of exogenous Put to affect the senescence of cut lisianthus flowers during vase life was investigated. Fresh cut lisianthus flowers were treated with distilled water (control), 0.5, 1 and 2 mM Put and then...

objective(s):althoughroutinely applied in assisted reproductive technology, human sperm cryopreservation is not a completely successful procedure. adverse effects of cryopreservation on the fertilization capacity, motility, morphology, and viability of spermatozoa have been proven; cryopreservation has also shown a role in sperm dna fragmentation and infertility. the post-thaw survival of sperm...
