background: nowadays it is proofed that the uterine artery plays essential role in follicular growth and/or post parturition hemorrhagic. objective: this study was conducted to evaluate the effect of bilateral uterine artery ligation (bual) on follicular fate and the probable histochemical changes of the carbohydrate and lipids in the ovaries of rabbits. materials and methods: 24 mature female ...

background: the exact pathophysiology of testicular degeneration, following varicocele has not been completely understood yet.   objective: the current study was designed to determine the effect of varicocele on germinal epithelium (ge) cytoplasmic biohistochmical alterations.   materials and methods: to follow-up this study, left varicocele was induced in test groups. non-varicocelized rats we...

abstract background: in this study we aimed to evaluate the impact of chronic exposure to the gly-phosate (gp) on rat’s testicular tissue and sperm parameters. objective: testicular tissue, morphology of sperms and testosterone level in serum of mature male rats were analyzed. materials and methods: animals were divided into two test and control-sham groups. the test group was subdivided into 4...

How mechanical forces are sensed remains largely mysterious. The forces that gate prokaryotic and several eukaryotic channels were found to come from the lipid membrane. Our survey of animal cells found that membrane force foci all have cholesterol-gathering proteins and are reinforced with cholesterol. This result is evident in overt force sensors at the tips of stereocilia for vertebrate hear...

Cells adapt to changing nutrient availability by modulating a variety of processes, including the spatial sequestration of enzymes, the physiological significance of which remains controversial. These enzyme deposits are claimed to represent aggregates of misfolded proteins, protein storage, or complexes with superior enzymatic activity. We monitored spatial distribution of lipid biosynthetic e...

Activating stimuli for T lymphocytes are transmitted through plasma membrane domains that form at T-cell antigen receptor (TCR) signalling foci. Here, we determined the molecular lipid composition of immunoisolated TCR activation domains. We observed that they accumulate cholesterol, sphingomyelin and saturated phosphatidylcholine species as compared with control plasma membrane fragments. This...

background: the present study was conducted in order to evaluate the effects of bilateral uterine artery ligation (bual) on the ovarian follicular fate, and alterations in carbohydrate, lipid, lipase and serum levels of f9sh, lh, prolactin, estrogen and progesterone. methods: twenty-four mature female rabbits divided into two test and control-sham groups. the animals underwent ovariohystrectomy...

Lactoferrin containing physiological amounts of iron is an inhibitor of lipid peroxidation induced by iron(III) salts and ascorbic acid. It might therefore help to protect neutrophils, inflammatory foci and secretions from metal-ion-dependent oxidative damage.

This paper describes an acoustic trap consisting of a multi-foci Fresnel lens on 127 μm thick lead zirconate titanate sheet. The multi-foci Fresnel lens was designed to have similar working mechanism to an Axicon lens and generates an acoustic Bessel beam, and has negative axial radiation force capable of trapping one or more microparticle(s). The fabricated acoustic tweezers trapped lipid part...
