Abstract
Polycystic ovary syndrome (PCOS) represents one of the leading causes of anovulatory infertility and affects 5% to 20% of women worldwide. Until today, both the subsequent etiology and pathophysiology of PCOS remain unclear, and patients with PCOS that undergo assisted reproductive techniques (ART) might present a poor to exaggerated response, low oocyte quality, ovarian hyperstimulation syndrome, as well as changes in the follicular fluid metabolites pattern. These abnormalities originate a decrease of Metaphase II (MII) oocytes and decreased rates for fertilization, cleavage, implantation, blastocyst conversion, poor egg to follicle ratio, and increased miscarriages. Focus on obtaining high-quality embryos has been taken into more consideration over the years. Nowadays, the use of metabolomic analysis in the quantification of proteins and peptides in biological matrices might predict, with more accuracy, the success in assisted reproductive technology. In this article, we review the use of human follicular fluid as the matrix in metabolomic analysis for diagnostic and ART predictor of success for PCOS patients.

Abstract
Type 1 diabetes (T1DM) is well recognized risk factor cardiovascular disease (CVD). Insulin therapy is recommended for all patients with type 1 diabetes. Previous findings showed that diabetes impairs endothelial function and increased glucose level reduces nitric oxide (NO) output and increases myeloperoxidase (MPO) activity. However, adiponectin (APN) decreases serum glucose levels. The current study evaluated effects of insulin therapy on circulating levels of oxidative stress and CVD biomarkers like NO, APN, MPO, AIP and lipid profile in type 1 diabetic patients. Fifty patients with T1DM and 18 healthy people were enrolled in this study. The recruited people with T1DM were classified into two groups: 22 newly diagnosed (untreated) type 1 diabetic patients and 28 insulin treated patients. In all groups, circulating NO, APN, MPO, AIP and lipids levels were measured. Compared to control, untreated diabetes revealed a significant increase in the serum levels of APN, MPO, TG, VLDL, TC, LDL and AIP, with a marked reduction in NO and HDL levels. However, insulin therapy significantly lowered MPO, TC and LDL, with no significant changes in the other biochemical parameters. As expected, oxidative stress and CVD-associated markers were significantly increased in untreated diabetes. Insulin therapy exhibited a relatively positive effect on oxidative stress and CVD biomarkers. Accordingly, insulin plus antioxidant supplementation required to normalize these parameters.

Abstract
Background Diabetes mellitus causes the deterioration of smooth muscle cells and interstitial matrix proteins, including collagen. Collagen and smooth muscle cells are abundant in the lungs, but the effect of diabetes on airway function and viscoelastic respiratory tissue mechanics has not been characterized. This study investigated the impact of diabetes on respiratory function, bronchial responsiveness, and gas exchange parameters. Methods Rats were allocated randomly to three groups: a model of type 1 diabetes that received a high dose of streptozotocin (DM1, n = 13); a model of type 2 diabetes that received a low dose of streptozotocin with a high-fat diet (DM2, n = 14); and a control group with no treatment (C, n = 14). Forced oscillations were applied to assess airway resistance (Raw), respiratory tissue damping (G), and elastance (H). The arterial partial pressure of oxygen to the inspired oxygen fraction (PaO2/FiO2) and intrapulmonary shunt fraction (Qs/Qt) were determined from blood gas samples at positive end-expiratory pressures (PEEPs) of 0, 3, and 6 cmH2O. Lung responsiveness to methacholine was also assessed. Collagen fibers in lung tissue were quantified by histology. Results The rats in groups DM1 and DM2 exhibited elevated Raw, G, H, and Qs/Qt, compromised PaO2/FiO2, and diminished airway responsiveness. The severity of adverse tissue mechanical change correlated with excessive lung collagen expression. Increased PEEP normalized the respiratory mechanics, but the gas exchange abnormalities remained. Conclusions These findings indicate that diabetes reduces airway and lung tissue viscoelasticity, resulting in alveolar collapsibility that can be compensated by increasing PEEP. Diabetes also induces persistent alveolo-capillary dysfunction and abnormal adaptation ability of the airways to exogenous constrictor stimuli.

Abstract
Sepsis is a life-threatening organ dysfunction caused by a deregulated host response to infection. This inappropriate response to micro-organism invasion is characterized by an overwhelmed systemic inflammatory response and cardiovascular collapse that culminate in high mortality and morbidity in critical care units. The occurrence of sepsis in diabetes mellitus (DM) patients has become more frequent, as the prevalence of DM has increased dramatically worldwide. These two important diseases represent a global public health concern and highlight the importance of increasing our knowledge of the key elements of the immune response related to both conditions. In this context, it is well established that the cells taking part in the innate and adaptive immune responses in diabetic patients have compromised function. These altered responses favor micro-organism growth, a process that contributes to sepsis progression. The present review provides an update on the characteristics of the immune system in diabetic and septic subjects. We also explore the beneficial effects of insulin on the immune response in a glycemic control-dependent and independent manner.

Abstract
Background Diabetic neuropathy is one of the most devastating ailments of the peripheral nervous system. Neuropathic pain develops in ∼30% of diabetics. Here, we examined the suppressive effect of GS-KG9 on neuropathic pain induced by streptozotocin (STZ). Methods Hyperglycemia was induced by intraperitoneal injection of STZ. Rats showing blood glucose level > 250 mg/dL were divided into five groups, and treatment groups received oral saline containing GS-KG9 (50 mg/kg, 150 mg/kg, or 300 mg/kg) twice daily for 4 wk. The effects of GS-KG9 on pain behavior, microglia activation in the lumbar spinal cord and ventral posterolateral (VPL) nucleus of the thalamus, and c-Fos expression in the dorsal horn of the lumbar spinal cord were examined. Results The development of neuropathic pain began at Day 5 and peaked at Week 4 after STZ injection. Mechanical and thermal pains were both significantly attenuated in GS-KG9-treated groups from 10 d after STZ injection as compared to those in the STZ control. GS-KG9 also repressed microglia activation in L4 dorsal horn and VPL region of the thalamus. In addition, increase in c-Fos-positive cells within L4 dorsal horn lamina I and II of the STZ control group was markedly alleviated by GS-KG9. Conclusion These results suggest that GS-KG9 effectively relieves STZ-induced neuropathic pain by inhibiting microglial activation in the spinal cord dorsal horn and VPL region of the thalamus.

Abstract
OBJECTIVE To evaluate the acute effects of insulin on airway reactivity and the protective effects of beclomethasone and ipratropium against insulin-induced airway hyperresponsiveness on isolated tracheal smooth muscle in a guinea pig model. MATERIALS AND METHODS The trachea of each guinea pig was excised; one end of the tracheal strip was attached to the hook of the oxygen tube of a tissue bath and the other end was connected to a research-grade isometric force displacement transducer. The effects of varying concentrations of insulin (10(-7) to 10(-3)M) and insulin pretreated with a fixed concentration of beclomethasone (10(-6)M) and ipratropium (10(-6)M) on the isolated tracheal tissue were studied by constructing cumulative concentration-response curves. Changes in tracheal smooth muscle contractions were recorded on a 4-channel oscillograph. RESULTS The means ± standard error of the mean of the maximum amplitude of contraction with increasing concentrations of insulin and of insulin pretreated with fixed concentrations of beclomethasone and ipratropium were 35 ± 1.13, 22 ± 1.15 and 27.8 ± 1.27 mm, respectively. CONCLUSION The data showed that beclomethasone inhibited the contractile response of insulin to a greater extent than ipratropium. Thus we suggest that inhalational insulin pretreated with beclomethasone may be more efficacious than with ipratropium for the amelioration of potential respiratory adverse effects such as bronchoconstriction.

Abstract
The present study aimed to determine whether curcumin isolated from the rhizome of Curcuma longa Linn could inhibit di-(2-ethylhexyl) phthalate (DEHP)-induced allergic inflammatory responses in human umbilical vein endothelial cells (HUVECs). We found that DEHP dose-dependently elevated adhesion molecule-1 (ICAM-1) protein level within 15-30 min, which was independent of de novo protein synthesis. And a late-phase induction of ICAM-1 was observed within 8 h treatment of DEHP via de novo protein synthesis through transcription and translation. DEHP also increased the expression of interleukin (IL)-8 in a time- and dose-dependent manner. Pretreatment with curcumin dose-dependently decreased DEHP-induced expression of ICAM-1 and IL-8 as well as phosphorylation of ERK1/2 and p38. Preincubation with ERK1/2 inhibitor (PD98059) or p38 inhibitor (SB203580) markedly blocked DEHP-stimulated activation of ICAM-1 and IL-8. We suggest that curcumin inhibits DEHP-induced expression of ICAM-1 and IL-8 through ERK and p38 MAPK signaling pathways in HUVECs and may contribute to ameliorate pathologies of DEHP-related allergic disorders.

Abstract
BACKGROUND Prostaglandin E(2) (PGE(2)) is thought to play a role in the pathogenesis of aspirin-sensitive asthma (ASA). OBJECTIVE We sought to extend our previous observations implicating impaired inflammatory cell responsiveness to PGE(2) as a pathogenetic mechanism in patients with aspirin-sensitive rhinosinusitis to the bronchial mucosa in patients with ASA. METHODS Immunohistochemistry was used to enumerate inflammatory cells and their expression of cysteinyl leukotriene receptors 1 and 2 (CysLT(1) and CysLT(2)) and the PGE(2) receptors E-prostanoid 1 to 4 (EP(1)-EP(4)) in bronchial biopsy specimens from patients with ASA, patients with aspirin-tolerant asthma, and control subjects (n= 15 in each group). Concentrations of PGE(2) in bronchoalveolar lavage fluid were measured by using ELISA. The effects of PGE(2) and EP receptor agonists on CD3/CD28-stimulated cytokine production by PBMCs were measured by using ELISA. Airways responsiveness to LTD(4)in vivo was measured in asthmatic patients by means of bronchial challenge. RESULTS Compared with patients with aspirin-tolerant asthma, patients with ASA had increased bronchial mucosal neutrophil and eosinophil numbers but reduced percentages of T cells, macrophages, mast cells, and neutrophils expressing EP(2). Both groups showed increased bronchial sensitivity to inhaled LTD(4), but this did not correlate with mucosal expression of CysLT(1) or CysLT(2). Bronchoalveolar lavage fluid PGE(2) concentrations were comparable in all groups. In vitro PGE(2) inhibited cytokine production by PBMCs through EP(2) but not other PGE(2) receptors. CONCLUSION Our data are consistent with the hypothesis that impaired inhibition of inflammatory leukocytes by PGE(2) acting through the EP(2) receptor has a role in the pathogenesis of ASA.
