We investigated the role of soluble guanylate cyclase in lipopolysaccharide-induced hyporesponsiveness to phenylephrine. The effects of phenylephrine on the blood pressure of female Wistar rats were evaluated at 2, 8, and 24 h after lipopolysaccharide injection (12.5 mg/kg i.p.). Vasoconstrictive responses to phenylephrine were reduced 40 to 50% in all time periods. Methylene blue, a soluble gu...

Background: Methotrexate (MTX) is one of the frequently used chemotherapeutic agents, especially in hematological malignancies and solid tumors. Objectives: MTX hepatotoxicity symptoms range from elevations in serum aminotransferases to hepatocyte necrosis and fibrosis. The time of medication administration significantly impacts treatment outcomes. Hence this study evaluated the protective eff...

background: induction of ovulation in art is necessary for superovulation and the side effects of superovulatory drugs are debated. oxytocin as a natural hormone, have receptors and is synthesized by several reproductive organs. preovulatory presence of oxytocin receptor mrnas in granulosa cells indicating a role for oxytocin in follicular development. objective: the aim of the present study wa...

Studies were designed to examine the expression and activity of four caspases that contribute to the initial (caspases-2, -8, and -9) and final (caspase-3) events in apoptosis in the rat corpus luteum (CL) during pregnancy (days 7, 17, 19, and 21 of gestation), postpartum (days 1 and 4), and after injection (0, 8, 16, 24, and 36 h) of the physiological luteolysin PGF2alpha. In addition, the tem...

PURPOSE The cytokines present in the aqueous humor and serum of C3H/HeN mice with endotoxin-induced acute anterior uveitis were analyzed, and the potential role of the cytokines in the pathogenesis of the disease was investigated. METHODS One hundred and eighty C3H/HeN mice were divided into an experimental group (n=150) and a control group (n=30). The mice in the experimental group were foot...

Carbonic anhydrase IX (CAIX) is a cell surface enzyme that is over-expressed in approximately 95% of cases of clear cell renal cell carcinoma (ccRCC), the most common renal cancer. We synthesized and performed in vitro and in vivo evaluation of a dual-motif ligand, [64Cu]XYIMSR-06, for imaging CAIX expression on ccRCC tumors using positron emission tomography (PET). [64Cu]XYIMSR-06 was generate...

The aim of this study was to examine the time course activation of select myogenic (MRF4, Myf5, MyoD, myogenin) and metabolic (CD36, CPT1, HKII, and PDK4) genes after an acute bout of resistance (RE) or run (Run) exercise. Six RE subjects [25 +/- 4 yr (mean +/- SD), 74 +/- 14 kg, 1.71 +/- 0.11 m] and six Run subjects (25 +/- 4 yr, 72 +/- 5 kg, 1.81 +/- 0.07 m, 63 +/- 8 ml.kg(-1).min(-1)) were s...

We evaluated the feasibility of systemic vascular perfusion with saline (mimicking plasmapheresis) as a method to enhance tumor-specific monoclonal antibody (MoAb) tumor/background ratios. Initially, groups of rats were injected intravenously (i.v.) with 131I-5G6.4 MoAb (murine IgG2aK reactive with ovarian carcinoma). These animal's radioactivity levels were determined by dose calibrator and th...

introduction: following a traumatic brain injury (tbi), the excessive release of proinflammatory cytokines is major cause of cerebral edema that can cause permanent neuronal loss. this study examined the changes in brain concentrations of proinflammatory cytokines il-1, il-6, tnf-α and tgf- after different doses of estrogen or progesterone treatment in brain-injured rats at 6 and 24 h post-in...
