Lipidomic profiling of chorionic villi in the placentas of women with chronic venous disease.
Background: Chronic venous disease (CVD) is a prevalent lower limb venous pathology that especially affects women, who also show an increased risk of this disease during pregnancy. Studies have shown significant structural changes in the placentas of women with CVD and several markers of tissue damage have been also described. Patients and Methods: To try to understand the different placental pathologies, research efforts have focused on examining metabolomic profiles as indicators of the repercussions of these vascular disorders. ⋯ In a study population of 12 pregnant women, 6 with and 6 without CVD, we compared through mass spectroscopy coupled to ultra-high performance liquid chromatography (UHPLC-MS), 240 metabolites in chorionic villus samples. Results: This study is the first to detect in the placental villi of pregnant women with CVD, modifications in lysophosphatidylcholines and amino acids along with diminished levels of other lipids such as triglycerides, sphingomyelins, and non-esterified omega 9 fatty acids, suggesting a role of these abnormalities in the pathogenesis of CVD. Conclusions: Our findings are a starting point for future studies designed to examine the impacts of CVD on maternal and fetal well-being.

Identifying the association between single nucleotide polymorphisms in KCNQ1, ARAP1, and KCNJ11 and type 2 diabetes mellitus in a Chinese population.
Background: Type 2 diabetes mellitus (T2DM) has a high global prevalence, and insufficient insulin secretion is one of the major reasons for its development. Therefore, investigating the association between T2DM and the single nucleotide polymorphisms (SNPs) in genes associated with insulin secretion is necessary. Methods: T2DM (1,194) and nondiabetic (NDM) (1,292) subjects were enrolled and the ten single nucleotide polymorphisms (SNPs) in KCNQ1, ARAP1, and KCNJ11 associated with insulin secretion were genotyped in a Chinese population. ⋯ For rs2237897, the C/T-T/T genotype is the protective factor compared to the C/C genotype (P<0.001, OR=0.74; 95% CI: 0.63-0.87). Furthermore, when compared with the rs2237897 (C/T-T/T) genotype, rs2237897C/C genotype showed higher HbA1C levels (8.731±2.697 vs 9.282±2.921, P=0.001). Conclusion: Our results revealed that genetic variations in KCNQ1 and ARAP1 were associated with T2DM susceptibility in a Chinese population.

Background: Sesamin is a major bioactive compound in sesame seeds and has various biological properties, including anti-inflammatory and anticancer activities. Here, we explored whether sesamin activates p53, which is widely inhibited in cervical cancer cells, thereby inducing p53-mediated apoptosis. Methods: Human HeLa and SiHa cervical cancer cells and normal Hs68 dermal cells were used as cell models. ⋯ Pifithrin-α also reduced apoptosis and restored the proliferation of HeLa and SiHa cells exposed to sesamin. Conclusions: These findings indicate that sesamin inhibits cervical cancer cell proliferation, and its mechanism may be attributed to the induction of p53/PTEN-mediated apoptosis. This suggests that sesamin might be useful as an adjuvant in promoting anti-cervical cancer treatments.

Inflammation-related prostate fibrosis (PF) is strongly associated with impaired urethral function and lower urinary tract symptoms (LUTS) severity. The aim of this study was to investigate the effects of RSV in patients with small prostate volume and LUTS. ⋯ After two months, only, group A patients treated with RSV showed significant symptomatic improvement of all NIH-CPSI and IPSS subscale scores, as well as a better EPS assay after prostate massage, in terms of high amount of prostatic volume and reduced white blood cells counts. Our data suggested pharmacological advantage after 2-month treatment with RSV in selected patients with PF for the treatment of voiding and storage complaints.

Hypercholesterolemia is a major risk factor for several cardiovascular and metabolic diseases as it triggers oxidative and pro-inflammatory cascades. Baicalein (BL) is a natural flavone with multiple therapeutic properties. The present study aimed to evaluate the potential protective effect of BL supplementation in hypercholesterolaemic rats. ⋯ Histological alterations induced by cholesterol overload in cardiac, hepatic, and renal tissues were ameliorated by BL supplementation. Our results show that the BL treatments (25 and 50 mg/kg/day) to HCD fed rats improved all the altered parameters. These results demonstrate that BL treatment improves cardiac, renal and hepatic dysfunctions in hypercholesterolaemic rats by activation of cellular antioxidant enzymes and/or suppression of inflammatory cytokines.
