background: male infertility is affected by several factors. lead is one of the heavy metals more bioavailable than usually modifies the sperm quality in humans. objective: the aim of this study was to establish the role of lead in semen quality in environmentally exposed men. materials and methods: semen and blood samples were obtained from two groups: the exposed group (eg=20) and the non-exp...

We report the discovery of a partial ∼ 2 diameter non-thermal radio shell coincident with Taz, the pulsar wind nebula (PWN) in the error box of the apparently variable γ-ray source 3EG J1809−2328. We propose that this radio shell is a newly identified supernova remnant (SNR G7.5−1.7) associated with the PWN. The SNR surrounds an amorphous region of thermal X-rays detected in archival ROSAT and ...

in this work, for the first time, the rheological properties of nanofluids of lanthania nanoparticles (nps) in ethylene glycol (eg) as functions of shear rate, volume fraction, and temperature were measured. the results showed that both eg and the nanofluids behave as non-newtonian fluids at lower shear rates and transform to newtonian fluids at higher shear rates. the values of viscosity for b...

The purpose of this study was to evaluate the use of glass capillary micropipette (GCM) as a vessel forvitrification of bovine oocytes. Cumulus-oocyte complexes (COCs) were obtained from slaughter-house andwashed 5 to 6 times in the washing medium (TCM-199 + 20% FBS) and randomly assigned to treatment andcontrol group. In the first step of vitrification, COCs were exposed to first vitrification...

BACKGROUND The media can have a profound impact on human behavior. A sensational murder by ethylene glycol (EG) poisoning occurred in our state. The regional media provided extensive coverage of the murder. We undertook this investigation to evaluate our incidence of EG poisoning during the timeframe of before the first report linking a death to ethylene glycol to shortly after the first murder...

The lamina cribrosa likely plays an important role in retinal ganglion cell axon injury in glaucoma. We sought to (1) better understand optic nerve head (ONH) structure and anterior lamina cribrosa surface (ALCS) microarchitecture between fellow eyes of living, normal non-human primates and (2) characterize the time-course of in vivo structural changes in the ONH, ALCS microarchitecture, and re...
