| The functional effect of the A>G transition at position 2756 on the MTR gene (5-methyltetrahydrofolate-homocysteine methyltransferase), involved in folate metabolism, may be a risk factor for head and neck squamous cell carcinoma (HNSCC). The frequency of MTR A2756G (rs1805087) polymorphism was compared between HNSCC patients and individuals without history of neoplasias. The association of this polymorphism with clinical histopathological parameters was evaluated. A total of 705 individuals were included in the study. The polymerase chain reaction-restriction fragment length polymorphism technique was used to genotype the polymorphism. For statistical analysis, the chi-square test (univariate analysis) was used for comparisons between groups and... |

| O presente trabalho avaliou o efeito de diferentes níveis de BAP (0; 2; 4; 6; 8 e 10miM) e de AIB (0; 0,5 e 1miM) na multiplicação in vitro da amoreira-preta cv. Tupy. O meio utilizado foi o MS suplementado com 100mg.<IMG SRC="http:/img/fbpe/cr/v32n5/11864s1.gif">-1 de mio-inositol, 30g.<IMG SRC="http:/img/fbpe/cr/v32n5/11864s1.gif">-1 de sacarose e 6g.<IMG SRC="http:/img/fbpe/cr/v32n5/11864s1.gif">-1 de ágar. Após a inoculação, as culturas foram mantidas em sala de cultura com 16 horas de fotoperíodo, temperatura de 25 ± 2ºC e radiação de 25µmoles.m-2.s-1. O número de gemas e o número de brotações foram avaliados com intervalo semanal, num total de quatro avaliações, e, na última avaliação, considerou-se a altura da brotação, bem como... |

| ABSTRACT 6-Gingerol is the major active constituent of ginger. In the current study, we aimed to investigate the mechanisms underlying the effects of 6-Gingerol on hair growth. Mice were randomly divided into five groups; after hair depilation (day 0), mice were treated with saline, or different concentrations of 6-Gingerol for 11 days. The histomorphological characteristics of the growing hair follicles were examined after hematoxylin and eosin staining. The results indicated that 6-Gingerol significantly suppressed hair growth compared with that in the control group. And choose the concentration of 6-Gingerol at 1 mg/mL to treated with mice. Moreover, 6-Gingerol (1 mg/mL) significantly reduced hair re-growth ratio, hair follicle number, and hair follicle... |

| ABSTRACT A new lactone, 7-epi-griffonilide (1), and six known compounds, 2, 3a - 3c, 4a and 4b, were isolated from the leaves of Bauhinia pentandra (Fabaceae). The structures elucidation of 1 and 2 were based on detailed 2D NMR techniques and spectral comparison with related compounds, leading to complete assignment of the 1H and 13C NMR spectra. |

| Abstract Uncoupling protein 2 (UCP2) decreases reactive oxygen species (ROS). ROS overproduction is a key contributor to the pathogenesis of diabetic kidney disease (DKD). Thus, UCP2 polymorphisms are candidate risk factors for DKD; however, their associations with this complication are still inconclusive. Here, we describe a case-control study and a meta-analysis conducted to investigate the association between UCP2 -866G/A and Ins/Del polymorphisms and DKD. The case-control study comprised 385 patients with type 1 diabetes mellitus (T1DM): 223 patients without DKD and 162 with DKD. UCP2 -866G/A (rs659366) and Ins/Del polymorphisms were genotyped by real-time PCR and conventional PCR, respectively. For the meta-analysis, a literature search was conducted... |

| Parkinson’s disease is a common neurodegenerative disorder. In this study, the monoamine oxidase inhibitory activity and potential anti-parkinsonian effects of 8-propyl-6H-[1,3]dioxolo[4,5-g]chromen-6-one (FCS303), a new synthetic coumarin, were evaluated. To do this, we used the reserpine model of Parkinson’s disease, an assay of levodopa/carbidopa potentiation, the catalepsy model of haloperidol, and an in vitro assay against monoamine oxidase (MAO) activity. Additionally, lipid peroxidation and protein carbonyl group quantification was performed in mice brain homogenates previously treated with haloperidol. FCS303 inhibited monoamine oxidase B (MAO-B) with an IC50 of 5.46 ± 0.36 µM; however, there was no effect on monoamine oxidase A (MAO-A). The oral... |

| ABSTRACT A 19-year-old patient who mistakenly received two doses of influenza vaccine 10 days before presentation, was admitted with malaise, weakness, and a purpuric non-blanching rash most prominent on the ankles followed by abdominal pain and hematochezia 72 h later. The diagnosis of influenza vaccine-related Henoch–Schonlein vasculitis was made. This complication, although rare, is the most common vasculitis related to immunization. |
