Oxidative stress has been identified as a crucial factor leading to male infertility largely due to peroxidativedamage to the sperm cell membrane. Cadmium (Cd) is a widespread environmental pollutant and oneof the well-known reproductive toxicants. Because of its long biological half-life (10–30 years), Cdaccumulates in the biological systems. The present study was designed to assess the concen...

Bone loss after spinal cord injury leads to increased fragility of bone and subsequent risk for low-trauma fractures in the sublesional parts of the body. Although in such injuries upper limbs are normally innervated, bone loss may occur in the upper extremities. The present study was designed to determine the systemic effects of spinal cord injury on the fracture healing of upper limbs in rabb...

Background: Parthenogenesis is the production of an embryo from a female gamete in the absence of any contribution from a male gamete, with or without the eventual development into an adult. In vivo, mammalian parthenogenesis is a rare event. Parthenogenesis can be efficiently induced in vitro with a variety of mechanical, chemical, and electrical stimuli in several species. Hydrostatic pressur...

Ultrasound has multiple industrial, medical and biotechnological applications. Ultrasound increases membrane permeability and causes several biological effects in plant cells. In this research, the effects of ultrasound on survival and growth of the sainfoin shoot apex explants were investigated. For this, shoot apex explants were exposed to ultrasonic waves (Frequency 37 kHz) for 0, 20, 30, 40...
