Prediction of the extent of germ cell loss utilising a noninvasive spectroscopy method in rat testicular damage model.

The aim of this study is to investigate the efficiency of elastic light single-scattering spectroscopy system, a noninvasive method, to acquire spectra during testicular biopsy from normal and damaged seminiferous tubules with various degrees of germ cell loss. Adult control rats and doxorubicin-injected rats to achieve seminiferous germ cell loss (for 10 days [10D], 20 days [D20], 30 days [D30], 40 days [D40], and 50 days [D50]) were used. Spectroscopic measurements were acquired utilising a single-fibre optical probe, and histopathology of the biopsied testicular tissue samples were compared.

Spatiotemporal expression and regulation of FoxO1 in mouse uterus during peri-implantation period.

Recent studies indicate that FoxO1 has roles in female reproductive system, especially in maternal endometrium. Although various cellular aspects and molecular pathways have been identified, the exact molecular characteristics of embryo implantation are still not completely understood. In this study, we aimed to investigate uterine expression and regulation of FoxO1 during peri-implantation period in mice.

Differential expression of mTOR signaling pathway proteins in lichen planopilaris and frontal fibrosing alopecia.

Dysregulation of the mammalian target of rapamycin (mTOR) signaling pathway has a variety of effects on the immune system and stem cell proliferation. Lichen planopilaris (LPP) and frontal fibrosing alopecia (FFA) are inflammatory scalp conditions resulting in permanent alopecia, which are thought to be related to stem cell damage. Here we investigate the expression of mTOR signaling pathway proteins in human hair follicles of LPP and FFA patients.

Evaluation of mTOR signaling pathway proteins in rat gastric mucosa exposed to sulfite and ghrelin.

Background/aims: Mammalian target of rapamycin (mTOR) signaling serves as a central regulator of cell growth, proliferation, and survival. In this study, we planned to evaluate the expressions of mTOR signaling constituents (p-p70S6K, p-mTOR, and p-Tuberin) in rat gastric mucosa and to compare the results in sulfite- and sulfite+ghrelin-exposed groups.

Materials And Methods: Rats were divided into three groups: the control group (C), the sodium metabisulfite (Na2S2O5) (S) group, and sulfite+ghrelin (SG) group.

Expression of CCM2 and CCM3 during mouse gonadogenesis.

Purpose: Three cerebral cavernous malformation (CCM) proteins, CCM1, CCM2, and CCM3, regulate cell-cell adhesion, cell shape and polarity, and most likely cell adhesion to extracellular matrix. Recently, CCM2 and CCM3 are known to be expressed in control and varicocele-induced rat testes, but little is known about these proteins during gonadogenesis. This led us to study the CCM proteins during the mouse gonadogenesis.

Aim: The aim of this study was to investigate whether poly(ADP-ribose) polymerase (PARP) inhibition improves endothelin-1 (ET-1)-induced endothelial dysfunction (ED).

Methods: Isolated rat thoracic aorta rings were incubated with ET-1 (10 nmol/L) in the presence or absence of either polyethylene glycol-superoxide dismutase (PEG-SOD; a cell-permeable superoxide radical scavenger, 41 U/mL) plus apocynin (a NADPH oxidase inhibitor, 300 µmol/L) or PJ34 (an inhibitor of polyADP-ribose polymerase, 3 µmol/L) for 18 h. Isometric tension studies were performed in response to acetylcholine (ACh; an endothelium-dependent vasodilator), sodium nitroprusside (SNP; an endothelium-independent vasodilator), and phenylephrine (Phe).

The expression pattern of PARP-1 and PARP-2 in the developing and adult mouse testis.

Although the importance of the PARP family members in the adult testis has already been acknowledged, their expression in the developing testis has not been addressed. We performed immunohistochemistry by using PARP-1 and PARP-2 antibodies on the developing mouse testis at embryonic day (E) 15.5, E17.

Pravastatin improves the impaired nitric oxide-mediated neurogenic and endothelium-dependent relaxation of corpus cavernosum in aged rats.

Aim: The aim of this study was to investigate the effect of pravastatin treatment on diminished corpus cavernosum (CC) function associated with aging.

Methods: Male rats were divided into three groups as adult rats (12-14 weeks old), aged rats (72-80 weeks old) and aged rats given 10 mg/kg/d pravastatin in drinking water for six weeks. Blood pressure was measured by tail-cuff method.

Ghrelin inhibits sodium metabisulfite induced oxidative stress and apoptosis in rat gastric mucosa.

This study aimed to investigate the effect of ghrelin administration on sulfite induced oxidative and apoptotic changes in rat gastric mucosa. Forty male albino Wistar rats were randomized into control (C), sodium metabisulfite (Na2S2O5) treated (S), ghrelin treated (G) and, Na2S2O5+ghrelin treated (SG) groups. Sodium metabisulfite (100 mg/kg/day) was given by gastric gavage and, ghrelin (20 μg/kg/day) was given intraperitoneally for 5 weeks.

Optimization of lipase-catalyzed synthesis of fructose stearate using response surface methodology.

In this study, immobilized lipase-catalyzed esterification reaction between fructose and stearic acid was examined for the synthesis of a useful compound, fructose stearate, using response surface methodology. The increase of water content in the reaction medium was the negative effect while the increase in initial stearic acid/fructose molar ratio was the greatest positive effect on the yield. The highest fructose stearate yield was obtained as 65% in tert-butanol.

Potential role of poly(ADP-ribose) polymerase (PARP) activation in methotrexate-induced nephrotoxicity and tubular apoptosis.
