Abstract
Our work was devoted to studying the effect of different concentrations of Mentha spicata aqueous extract on the green synthesis of silver nanoparticles (AgNPs) in order to obtain the most effective of these concentrations for bacteria inhibitory activity. Different concentrations of the aqueous M. spicata extract (0.25, 0.50, 0.75, and 1.00 mM) were used as biological solvent to synthesize AgNPs by means of the reduction method. The crystal structure and morphology of the NPs were characterized UV–vis spectra, X-ray diffraction (XRD), and scanning electron microscopy (SEM). The inhibition effect of AgNPs on Escherichia coli was studied to determine the minimum inhibitory concentration (MIC). The dark yellow color of the M. spicata extract aqueous solution indicates the successful synthesis of the AgNPs. UV spectra of the NPs show a gradual increase in absorption with increasing concentration of aqueous M. spicata extract solution from 0.25 to 1.00 mM, accompanied by a shift in the wavelength from 455 to 479 nm along with a change in the nanoparticle size from 31 to 9 nm. The tests also showed a high activity of the particles against bacteria (E. coli) ranging between 15.6 and 62.5 µg/ml. From the AgNPs, it was confirmed that aqueous M. spicata extract is an effective biosolvent for the synthesis of different sizes of AgNPs according to the solvent concentration. The AgNPs also proved effectual for the killing of bacteria.

Abstract
This study examined the effect of varying concentrations of Ocimum basilicum aqueous extract, which was done via the green synthesis of Silver nanoparticles (AgNPs), on the identification of the most effective concentration for bacteria inhibitory activity. Different concentrations of the aqueous Ocimum basilicum extract (0.25, 0.50, 0.75 and 1.00 mM) were used as reducing and stabilizing agent to synthesize AgNPs by means of the reduction method. The crystal structure and morphology of the NPs were characterized UV-Vis spectra, X-ray diffraction (XRD) and scanning electron microscopy (SEM). The antibacterial efficacy of AgNPs was studied against E. coli ATCC 35218 using well diffusion, MIC, MBC, and time-kill curve. The dark yellow color of the Ocimum basilicum aqueous solution indicates the successful synthesis process of the AgNPs. UV-spectra of the AgNPs display a gradual increase of absorption in sequence with concentration increase of aqueous Ocimum basilicum extract solution from 0.25 to 1.00 mM. This, in turn, led to a shift in the wavelength from 488 to 497 nm, along with a change in the nanoparticle size from 52 to 8 nm. The tests also showed a high activity of the particles against bacteria (E. coli), ranging between 15.6 and 62.5 µg/ml. Based on AgNPs, it was confirmed that an aqueous Ocimum basilicum extract can be used as an effective, reducing and stabilizing agent for the synthesis of different sizes of AgNPs based on the solvent concentration. The AgNPs also proved to be effective in inhibiting and killing bacteria.

Abstract
Association of hepatitis C virus (HCV) with autoimmune phenomena and impaired semen parameters has been previously reported. The aim of this study was to investigate the influence of HCV infection on the development of antisperm antibodies (ASAs) in HCV-positive males. The study was conducted on 30 HCV-infected individuals and 30 healthy control subjects. In both patients and control groups, liver enzymes and reproductive hormones were measured; computer-assisted semen analysis (CASA) was performed; HCV-RNA in serum was measured and IgG and IgA ASAs in semen were determined. Free testosterone, sperm concentration, progressive and total motility were significantly lower in HCV patients than in the control group, whereas ASAs of the IgG and IgA classes were significantly higher in HCV patients. However, correlations between viral load and the examined semen parameters and ASAs were nonsignificant. In conclusion, HCV may be responsible for the increased ASAs detected in HCV patients in the present study, possibly providing another plausible explanation for the decreased sperm motility reported in HCV patients. These findings could be of value in fertility management of HCV patients.

Abstract
Endometriosis is defined as endometriotic tissue growing outside the uterine cavity. It is a common gynecological disorder in women of reproductive age and is associated with chronic pelvic pain and infertility. Despite several studies and theories to explain its cause, the exact pathogenesis of endometriosis remains unclear. Retrograde menstruation is the most plausible theory, however, it is not exclusive. The disparity between the actual prevalence of retrograde menstruation and the prevalence of endometriosis suggests that other factors may determine the susceptibility to endometriosis development. Oxidative stress has been associated with endometriosis. This study aimed to explore the role of NADPH oxidase family in the production of reactive oxygen species (ROS) and to determine whether ROS induce the proliferation of endometriotic implants via mammalian target of rapamycin (mTOR) signaling. Anonymous endometriotic tissue samples were collected from women undergoing laparoscopy for endometriosis. The samples were stained with dihydroethidium and fluorescent images of the slides were taken to detect ROS production. After extraction of RNA from the samples and c-DNA generation, quantitative real-time PCR, protein extraction and Western blot were performed to study gene and protein expression of NADPH oxidase 1 (NOX 1), mTOR and fibronectin. The results showed an increase in ROS levels and NOX 1 gene and protein expression in the endometriotic tissues compared to the normal surrounding tissue control. Also, mTOR and fibronectin, gene expression was found to be increased. Up regulation of NOX at gene and protein level leads to increased production of ROS in the endometriotic tissue, which in turn causes proliferation of the ectopic tissue via alteration of the mTOR signaling pathway. Increased fibronectin gene expression points towards tissue injury in endometriosis as compared to the normal surrounding tissue. This manuscript adds a new insight into the pathogenesis of endometriosis and serves as a background for development of new treatments for the disease-associated pain and infertility.

Abstract
Diabetic nephropathy (DN) is one of the most serious complications of type I and type II diabetes. DN is characterized by hyperfiltration, hypertrophy, extracellular matrix accumulation, and proteinuria. This advances into renal fibrosis and loss of renal function. Reactive oxygen species (ROS) and TGF-beta have been implicated in the pathogenesis of diabetic nephropathy. Early stages of diabetic nephropathy are also associated with alterations in renal sodium handling as well as hypertension; both are processes linked by involvement of the arachidonic acid (AA) metabolites, 20-hydroxyeicosatetraenoic acid (20-HETE, produced by cytochrome P450-4a, (CYP4A) and epoxyeicosatrienoic acids (EETs). Indeed, metabolism of AA is increased in a rat model of diabetes. In this study, we demonstrate that rats with streptozotocin-induced diabetes of 1 month duration develop renal hypertrophy and increased fibronectin and TGF-beta1 expression/cortical levels concomitant with an increase in CYP4A expression and 20 HETE production. These results were also paralleled by an increase in reactive oxygen species (ROS) production and NADPH oxidase activity. Treatment of diabetic rats with HET0016, selective inhibitor of CYP 4A, prevented all these changes. Our results suggest that diabetes-induced induction of CYP4A and 20-HETE production could be a major pathophysiological mechanism leading to activation of ROS through an NADPH dependent pathway and TGF-beta1 thus resulting in major renal pathology. Inhibitors of 20-HETE production could thus have an important therapeutic potential in the treatment of diabetic nephropathy.

Abstract
Weight loss in chronic obstructive airways disease (COPD) is associated with an increased energy cost of breathing. To determine an association between body composition and the inflammatory response we studied 80 clinically stable patients. Body composition was determined anthropometrically and skeletal muscle mass was determined as the creatinine-height index (CHI). Forty patients had their nitrogen balance determined. Circulating concentrations of interleukin 6 (IL-6), tumor necrosis factor alpha (TNF-alpha), and their soluble receptors were determined for 68 patients. Body mass index (BMI) was normal (> 20 kg/m(2)) in 55 patients, of whom 17 (31%) had a low CHI (< 80% predicted). A reduced CHI was associated with increased circulating levels of IL-6 (p = 0.001), TNF-alpha (p = 0.032) and their soluble receptors IL-6sr (p = 0.002), TNF-alpha sr1 (p = 0.03), and TNF-alpha sr2 (p = 0.001). Patients with a normal BMI and low CHI had inflammatory mediator levels similar to patients with a low BMI and CHI; both were significantly greater than in those with a normal BMI and CHI. Nitrogen balance was similar between normal and low CHI groups, although nitrogen excretion was significantly increased in the low CHI group. Skeletal muscle loss in COPD is probably multifactorial in origin, but our data suggest a link with systemic inflammation, even when weight loss is inapparent.

Abstract
BACKGROUND Alterations in Starling forces that favor pleural fluid formation include an elevation in capillary hydrostatic pressure and a fall in plasma oncotic pressure. Although venous hypertension is a well-recognized cause of pleural effusion, the frequency with which hypoalbuminemia in the absence of volume expansion leads to pleural effusion is unclear. STUDY OBJECTIVE We determined the frequency with which unexplained pleural effusions occur in patients with normal and low plasma oncotic pressures. DESIGN A 2-month prospective screen of all admission patients to the University of Oklahoma Hospital and the Oklahoma City Veterans Administration (VA) Medical Center identified 152 patients who had chest radiographs and serum protein determinations on admission, but did not have an admission diagnosis that was a recognized cause of pleural effusion. In order to include more patients in the study with extremely low serum albumin levels, 20 additional study patients with serum albumin levels of < 2.0 g/dL were identified by a retrospective review of patients admitted during the previous 12 months. On the radiograph, pleural effusions were identified as a new blunting of the costophrenic angles. Study patients were divided into the following three groups: group 1 had serum albumin levels of > 3.5 g/dL; group 2 had serum albumin levels between 2.1 and 3.5 g/dL; and group 3 had serum albumin levels of < or = 2.0 g/dL. Finally, the frequencies with which pleural effusions occurred were compared among the three groups. RESULTS Seven of 104 patients in group 1, 2 of 45 patients in group 2, and 3 of 21 patients in group 3 had pleural effusions. Within each group, there were no significant differences in serum albumin concentration or plasma oncotic pressure between patients with and without pleural effusions. In all but two study patients, a careful review of records and a prospective follow-up of the patients' clinical course identified a potential cause for the effusions other than hypoalbuminemia. None of the 68 study patients with serum albumin levels of < or = 3.5 g/dL had an unexplained pleural effusion. CONCLUSION We conclude that hypoalbuminemia, per se, is an uncommon cause of pleural effusion. The recognition of pleural effusions in patients with low serum albumin levels should prompt careful clinical evaluations to identify other potential causes for the effusions.
