Abstract
Oxidative stress (OS) plays an important role in all physiological processes. The effect of OS on cellular processes is modulated by the ability of the cell to express genes implicated in the reversal of lipid, protein, and DNA injury. Aldehyde dehydrogenase 3, member A2 (ALDH3A2) is a ubiquitous enzyme involved in lipid detoxification. The objective of this study was to investigate the expression ofALDH3A2in human granulosa-lutein (GL) cells of women undergoing in vitro fertilization (IVF) and its relationship with age, infertility diagnosis, and IVF outcome variables. Relative expression levels ofALDH3A2were determined by quantitative reverse transcription-polymerase chain reaction. To investigate the effect of age onALDH3A2expression, 72 women between 18 and 44 years of age with no ovarian factor (NOF) were analyzed. To evaluate the effect of infertility diagnosis onALDH3A2expression, the following groups were analyzed: 22 oocyte donors (ODs), 24 women >40 years old (yo) with tubal or male factor and no ovarian pathology, 18 poor responders (PRs), 19 cases with endometriosis (EM), and 18 patients with polycystic ovarian syndrome (PCOS). In NOF,ALDH3A2expression correlated positively with age and with the doses of follicle-stimulating hormone and luteinizing hormone administered and negatively with the number of total and mature oocytes. When different groups were analyzed,ALDH3A2expression levels were higher in patients >40 yo and in PR compared to OD. On the contrary, EM and PCOS levels were lower than expected for age. These data suggest that GL cellALDH3A2expression levels correlate with age, cause of infertility, and ovarian response to stimulation.

Hesperetin Induces the Apoptosis of Gastric Cancer Cells via Activating Mitochondrial Pathway by Increasing Reactive Oxygen Species. Dig Dis Sci 2015; 60:2985-95. [PMID: 25972151 DOI: 10.1007/s10620-015-3696-7] [Citation(s) in RCA: 50] [Impact Index Per Article: 5.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/05/2015] [Accepted: 04/29/2015] [Indexed: 01/19/2023]
Abstract
BACKGROUND Hesperetin, has been shown to exert biological activities on various types of human cancers. However, few related studies on gastric cancer are available. AIM In this study, we sought to investigate the effect of hesperetin on gastric cancer and clarify its specific mechanism. MATERIALS AND METHODS Cell Counting Kit-8, 2',7'-dichlorofluorescin diacetate, JC-1, Hoechst 33258 staining, and western bolt were used to detect cell viability, levels of intracellular reactive oxygen species (ROS), changes in mitochondrial membrane potential (△ψ m), cell apoptosis, and expressions of mitochondrial pathway proteins, respectively. Meanwhile, xenograft tumor models in nude mice were made to evaluate the effect of hesperetin on gastric cancer in vivo. RESULTS Compared with the control group, the proliferation of gastric cancer cells in hesperetin groups was significantly inhibited (P < 0.05), and dose- and time-dependent effects were observed. Pretreatment with H2O2 (1 mM) or N-acetyl-L-cysteine (5 mM) enhanced or attenuated the hesperetin-induced inhibition of cell viability (P < 0.05). Percentages of apoptotic cells, levels of intracellular ROS, and △ψ m varied with the dose and treatment time of hesperetin (P < 0.05), and hesperetin caused an increase in the levels of AIF, Apaf-1, Cyt C, caspase-3, caspase-9, and Bax and a decrease in Bcl-2 levels (P < 0.05). Meanwhile, hesperetin significantly inhibited the growth of xenograft tumors (P < 0.05). CONCLUSION Our study suggests that hesperetin could inhibit the proliferation and induce the apoptosis of gastric cancer cells via activating the mitochondrial pathway by increasing the ROS.

Abstract
Recently, the association of polymorphism rs1800562 (p.C282Y) in the hemochromatosis (HFE) gene with the increased risk of venous ulceration was shown. We hypothesized that HFE gene polymorphism might be involved not only in ulceration process, but also in susceptibility to primary varicose veins. We genotyped HFE p.C282Y (rs1800562) and p.H63D (rs1799945) variants in patients with primary varicose veins (n = 463) and in the control group (n = 754). In our study, p.282Y variant (rs1800562 A allele) was significantly associated with the risk of varicose veins (OR 1.79, 95 % CI = 1.11-2.89, P = 0.02). A borderline significant reverse association of p.63D variant (rs1799945 G allele) with venous leg ulcer development was revealed in Russians (OR 0.25, 95 % CI = 0.06-1.00, P = 0.05), but not in the meta-analysis (P = 0.56). We conclude that the HFE gene polymorphism can affect the risk of developing primary varicose veins.

Abstract
Advanced glycation end products (AGEs) formed via the Maillard reaction during the thermal processing of food contributes to the flavor, color, and aroma of food. A proportion of food-derived AGEs and their precursors is intestinally absorbed and accumulates within cells and tissues. AGEs have been implicated in the pathogenesis of diabetes-related complications and several chronic diseases via interaction with the receptor for AGEs, which promotes the transcription of genes that control inflammation. The dicarbonyls, highly reactive intermediates of AGE formation, are also generated during food processing and may incite inflammatory responses through 1) the suppression of protective pathways, 2) the incretin axis, 3) the modulation of immune-mediated signaling, and 4) changes in gut microbiota profile and metabolite sensors. In animal models, restriction of dietary AGEs attenuates chronic low-grade inflammation, but current evidence from human studies is less clear. Here, the emerging relationship between excess dietary AGE consumption and inflammation is explored, the utility of dietary AGE restriction as a therapeutic strategy for the attenuation of chronic diseases is discussed, and possible avenues for future investigation are suggested.

Comparing Changes in Plasma and Skin Autofluorescence in Low-Flux versus High-Flux Hemodialysis. Int J Artif Organs 2015; 38:488-93.

Abstract
Background Tissue advanced glycation end products (AGE) are increased in hemodialysis (HD) patients, especially those with cardiovascular complications. Skin autofluorescence (skin-AF) can noninvasively estimate the accumulation of AGE in tissue. The aim was to clarify whether HD using a high-flux (HF) dialyzer favors plasma- or skin-AF removal compared to low-flux (LF) dialysis. Material and methods 28 patients were treated with either an HF-HD or LF-HD but otherwise unchanged conditions in a cross-over design. A glucose containing dialysate was used. Skin-AF was measured noninvasively with an AGE reader before and after HD. Fluorescence (370 nm/465 nm) of plasma (p-AF) was determined as total and nonprotein-bound fractions. Correction for hemoconcentrations were made using the change in serum albumin. Paired and nonpaired statistical analyses were used. Results Skin-AF was unchanged after LF- and HF-dialysis. Total, free, and protein- bound p-AF was reduced after a single LF-HD by 21%, 28%, and 17%, respectively ( P<.001). After HF HD total and free p-AF was reduced by 5% and 15%, respectively ( P<.001), while protein bound values were unchanged. The LF-HD resulted in a more pronounced reduction of p-AF than did HF HD ( P<.001). Serum albumin correlated inversely with p-AF in HF-HD. Conclusions In the dialysis settings used there was no significant change in skin AF after dialysis, with LF or with HF dialysis. Although only limited reduction in plasma fluorescence was observed, this was more pronounced when performing LF dialysis. These data are not in overwhelming support of the use of HF dialysis in the setting used in this study.

Abstract
Oxidative stress is one of the risk factors for the development of several chronic diseases, such as diabetes, cancer, cardiovascular and neurodegenerative diseases. Antioxidants are therefore highly sought and can be seen as a type of preventive medicine against several diseases. Myrica and Morella genus (Myricaceae) are taxonomically very close and their species are trees or shrubs with edible fruits that exhibit relevant uses in traditional medicine, for instance in Chinese or Japanese folk medicine they are used to treat diarrhea, digestive problems, headache, burns and skin diseases. Nearly 36 compounds were isolated from different morphological parts of Myrica and/or Morella species and their antioxidant and anti-inflammatory activities evaluated. Thirteen of these compounds exhibit greater effects than the positive controls used. Adenodimerin A was the most active compound reported (in a 2,2-diphenyl-1-picrylhydrazyl (DPPH) assay EC50= 7.9 ± 0.3 µM). These results are just one aspect of the antioxidant and anti-inflammatory evaluations reported regarding Myrica and Morella species, so a comprehensive overview on the current status, highlighting the antioxidant health promoting effect of these species, their key antioxidant compounds as well as the compounds with protective effects against oxidative stress related diseases such as inflammation, is relevant.

Abstract
Social isolation rearing (SIR) is an early stress paradigm of deprivation of the social contact since weaning. SIR has been used to investigate the mechanisms behind certain mental illnesses with neurodevelopmental origins, including schizophrenia. In schizophrenia, metabolic dysfunction has become a critical issue with increasing evidence for a possible connection between metabolism and immune systems in which metabolic changes are associated with pro-inflammatory cytokine (pro-CK) levels. The present study employed a rat model of SIR with both sexes to examine behaviors [locomotor activity and prepulse inhibition (PPI)], inflammatory markers [C-reactive protein, interleukin (IL)-1 beta, IL-6, IL-10, tumor necrosis factor (TNF)-alpha and interferon-gamma], and metabolism-related variables (body weight, blood pressure, and the profiles of glycemia and lipid). Our results revealed that around puberty, SIR rats of both sexes exhibited behaviorally a higher locomotor activity and a lower PPI performance. Biochemically, SIR rats had an elevated level of pro-CKs (IL-1 beta, IL-6, TNF-alpha, and interferon-gamma), and metabolic abnormalities (increased insulin resistance, decreased insulin sensitivity, and high blood pressure) in a time-dependent manner. The relationships between pro-CKs and metabolism were sex specific as IL-1 beta and interferon-gamma were correlated to glycemia metabolic indexes in males. The present study demonstrated SIR-induced longitudinal concomitant changes of pro-CKs and metabolic abnormalities, implying a more direct role of these two things in mental dysfunctions with a developmental origin.
