Additionally, treatment with eugenol was found to reduce intracellular ROS levels while increasing cellular resistance to H2O2, in a manner that was dependent on Nrf2. In conclusion, data from the present study suggest that eugenol is a protective agent against oxidative stress that exerts its effects through a Nrf2-dependent pathway, rendering eugenol and its derivatives to be promising candidates for the future development of antioxidants.High glucose metabolism is recognized as one of the hallmarks of cancer and increased expression levels of several key factors involved in glucose metabolism have been reported in non-small cell lung cancer (NSCLC). Previous studies showed that microRNA (miR)-218 is reduced in NSCLC, but its function in glucose metabolism in NSCLC is not fully understood. Y-27632 The present study aimed to investigate the effect of miR-218 on glucose metabolism in NSCLC cell lines and the underlying molecular mechanism. The present results suggested that miR-218 reduced glucose consumption, the mechanism of glycolysis and activity in the pentose phosphate pathway. In addition, glucose transporter 1 (GLUT1) was identified to be a direct target of miR-218, while overexpression of GLUT1 did not abolish the effect of miR-218 on glucose metabolism. The present results indicated that phosphorylation of NF-κB p65 was significantly decreased by miR-218 in NSCLC cells and that activation of NF-κB led to the inhibition of miR-218 regulation of glucose metabolism. In conclusion, the present results suggested that miR-218 downregulated glucose metabolism in NSCLC not only by directly targeting GLUT1, but also via the NF-κB signaling pathway.The present study aimed to investigate dietary vitamin intake levels and their association with the prevalence of obesity, hypertension, dyslipidemia and hyperglycemia in centenarians in China. From June 2014 to December 2016, a total of 992 centenarians aged >99 years (177 males and 815 females; age range, 100-115 years) were enrolled through household visits in the cities and rural areas of Hainan province. Details regarding food intake were recorded by continuous collection of 7-day food frequency and 24-h dietary review, and dietary vitamin intake levels were calculated according to the Chinese Food Composition Table. The deficiency rates of vitamin A (VA), VE, VB1, VB2, niacin and VC among the centenarians were relatively high and the prevalence of metabolic syndrome (MS) was 53.67% (519/967). The dietary intake levels of VA, VE and PP were significantly higher among the healthy centenarians than among the centenarians with MS (P less then 0.05). Compared with the lowest quartiles (Q1) of dietary vitamin intake, higher dietary intake levels of VA (Q4) [odds ratio (OR)=0.72; 95% CI 0.38, 0.99], VE (Q3) (OR=0.61; 95% CI=0.36, 0.88) and VB2 (Q4) (OR=0.51; 95% CI 0.32, 0.81) were associated with a reduced risk of hypertension (P less then 0.05). However, higher dietary intake levels of VA, VE, VB2 and PP were associated with increased risks of central obesity, hyperglycemia and low high-density lipoprotein cholesterol levels. A high prevalence of MS and vitamin deficiency were detected among the centenarians and these two items were associated with each other. It was indicated that specific vitamins are necessary for certain centenarians.Limb-girdle muscular dystrophies (LGMDs) are a group of neuromuscular diseases that are characterized by progressive muscle weakness. LGMD type 2A (LGMD2A), caused by variants in the calpain-3 (CAPN3) gene, is the most prevalent type. The present study aimed to analyze pathogenic CAPN3 gene variants in two pedigrees affected by LGMD2A. Each family contains three patients who are siblings and sought genetic counseling. Genomic DNA was extracted from the peripheral blood samples collected from the probands and family members and whole-exome sequencing (WES) was used to detect the pathogenic genes in the probands. Suspected variants were subsequently validated by Sanger sequencing. In family 1, WES revealed that the proband carried the compound heterogeneous variants c.1194-9A>G and c.1437C>T (p.Ser479=) in CAPN3 (NM_000070.2). In family 2, WES identified that the proband carried the compound heterogeneous variants c.632+4A>G and c.1468C>T (p.Arg490Trp) in CAPN3 (NM_000070.2). In conclusion, the present study indicated that the compound heterogeneous variants of the CAPN3 gene were most likely responsible for LGMD2A in the two Chinese families.The presence of certain soluble factors may provide a possible selective advantage for a parasite to gradually modify cell proliferation in neighbouring cells, which may result in chronic diseases. These soluble factors present in the conditioned medium also allow the parasite to invade rapidly into more host cells. The present study aimed to determine the levels of a group of type 1 T helper (Th1) cytokines in the conditioned media of host cells infected with parasites and in IL-21-silenced colorectal cancer cells. The conditioned media of human foreskin fibroblasts (HFFs) parasitized with the RH and ME49 strains of Toxoplasma gondii for 10 days were prepared, and subsequently the levels of the Th1 cytokines in the conditioned media were determined by ELISA. HFFs were incubated with the growth media containing selected soluble factors, and cell proliferation markers were subsequently analysed by reverse transcription-quantitative PCR. The mRNA expression level of cell proliferation markers was also examined relevant endemic regions.

Neoadjuvant anthracycline-taxane-based chemotherapy (ChT) is a standard of care treatment option for stage II-III breast cancer (BC) patients. However, the optimal duration of neoadjuvant ChT has been poorly investigated so far.

We retrospectively retrieved clinical data of patients with stage II-III human epidermal growth factor receptor 2-negative (HER2-) BC who were treated between October 2007 and January 2018 with neoadjuvant AT (doxorubicin-paclitaxel) for three cycles followed by CMF (cyclophosphamide-methotrexate-5-fluorouracil) for three cycles (cohort A) or with four AT cycles followed by four CMF cycles (cohort B). The aim of our study was to investigate the impact of neoadjuvant ChT duration (cohort A

cohort B) on pathological complete response (pCR) rates, disease-free survival (DFS) and overall survival (OS).

Of 209 HER2- BC patients included, 62 had triple-negative breast cancer (TNBC) and 147 had hormone receptor-positive (HR+) BC. Median age was 48 years (range 30-74 years). A total of 111 patients belonged to cohort A and 98 patients belonged to cohort B.
