mechanisms for linuron and is the first to demonstrate that this anti-androgenic chemical impairs oxidative respiration and exerts neurotoxic effects associated with neurotransmitter biosynthesis during early development. These data are significant for environmental risk assessment of agrochemicals.Glycosmis pentaphylla (Retz.) DC (Rutaceae) has been traditionally considered as anti-cancer and anti-inflammatory medicine. However, active compounds of sulphur-containing amides remain largely unknown. In the present work, eighteen previously undescribed sulphur-containing amides (1-18) and three known analogues (19-21) were isolated from the leaves of G. pentaphylla. Their structures were elucidated by NMR spectroscopy and mass spectrometry. All isolated prenylated sulphur-containing amides were evaluated for their anti-inflammatory properties together with antiproliferative activities in vivo. Prenylated sulphur-containing amides exhibited significant inhibitory effects against nitric oxide (NO) production stimulated by lipopolysaccharide in mouse macrophage RAW 264.7 cells with the IC50 values ranging from 0.16 ± 0.10 to 16.74 ± 2.81 μM. Meanwhile, sulphur-containing amides also exhibited considerable antiproliferative activities against HepG2 cell line with IC50 values ranging from 7.47 ± 0.91 to 16.23 ± 0.80 μM. These findings enrich and improve the research on the structural diversity and biological activity of sulphur-containing amides and provide phytochemical and pharmacological evidence for the further development and utilization of the leaves of G. pentaphylla in pharmaceutical industry.Resins from various Boswellia species have a long track record in different cultures as a treatment for inflammatory diseases. This study was designed to provide evidence for the anti-inflammatory capacity and medicinal use of Boswellia carteri (Burseraceae). A dichloromethane (DCM) extract of B. carteri gum resin and isolated compounds thereof were immunologically characterized. Flow cytometric-based analysis was performed to investigate the impact of B. carteri extract on proliferation, viability, and function of anti-CD3 and anti-CD28 activated human primary T cells. selleckchem The secretion level of IL-2 and IFN-γ was determined by a bead array-based flow cytometric technique. HPLC-based activity profiling of the B. carteri extract identified active compounds. The impact of B. carteri extract and isolated compounds on the IL-2 transcription factor activity was addressed using specially designed Jurkat reporter cells. The extract of B. carteri suppressed the proliferation of human primary T lymphocytes in vitro in a concentration-dependent manner, without inducing cytotoxicity. Thereby, the B. carteri extract further reduced the degranulation capacity and cytokine secretion of stimulated human T cells. Transcription factor analysis showed that the immunosuppressive effects of the extract are based on specific NFAT-conditioned suppression within T cell signaling. Through HPLC-based activity profiling of the extract, 3-O-acetyl-alpha-boswellic acid was identified as the compound responsible for the NFAT-based mechanism. The recent study presents a scientific base for the immunosuppressive effects of B. carteri gum resin extract including a mode-of-action via the NFAT-conditioned suppression of T lymphocyte proliferation. The immunosuppressive effects of 3-O-acetyl-alpha-boswellic acid are depicted for the first time.Chemical examination of the fermented material of the deep-sea-derived fungus Penicillium thomii YPGA3 led to the identification of a rare 19-nor labdane-type diterpenoid, named penitholabene (1). The structure was elucidated based on extensive analyses of the spectroscopic data and quantum chemical calculations of the 13C NMR and ECD data. A synthetic compound from commercial sources with the same planar structure is recorded in SciFinder (CAS number 1217878-75-5), but there is no related reference and the configurations of chiral centers and double bond are not depicted. Penitholabene was reported as a new compound in the current study. To our knowledge, Penitholabene represents the first 19-nor labdane-type diterpenoid found in nature. It showed inhibitory effect against α-glucosidase with an IC50 value of 282 μM, being more active than the positive control acarbose (1.33 mM).

To evaluate the evolving role of gender in invited authorship and editorial positions in the Journal of Pediatric Urology.

We recorded editorial board members and first and senior authors for all editorials and invited commentaries for all issues of the Journal of Pediatric Urology from 2005 to August 2018. We also recorded first and senior authors for original research articles from selected years for comparison. Gender was confirmed for each individual by visiting institutional websites and performing internet searches. The same was done for the Societies for Pediatric Urology membership.

A total of 143 editorials and 162 invited commentaries were identified within the study period, with numbers increasing each year. Overall, these publications had 448 first and senior authorships, of which 10% were female. Of the 898 editorial board positions over the study period, 7% were held by females. The proportion of female authorships increased over time (P = .04), while the proportion of female board members did not (P = .9).

Female invited authorship has increased over the past 13 years in the Journal of Pediatric Urology. However, editorial board membership has lagged, indicating an opportunity for improvement.

However, the use of hemicellulosic hydrolysates is limited due to the presence of C5-sugars and inhibitors formed during pretreatment. Bacillus coagulans is one of the few bacteria able to utilize both C6- and C5-sugars to produce l-lactic acid, but its susceptibility to the lignocellulosic inhibitors needs further investigation. For such a purpose, the tolerance of different B. coagulans strains to increasing concentrations of inhibitors is studied. The isolated A162 strain reached the highest l-lactic acid productivity in all cases (up to 2.4 g L-1  h-1), even in presence of 5 g L-1 of furans and phenols. Remarkably, most of furans and phenolic aldehydes were removed from defined media and hemicellulosic gardening hydrolysate after fermentation with A162. Considering the high productivities and the biodetoxifying effect attained, A162 could be pointed out as a great candidate for valorisation of mixed sugars from hemicellulosic hydrolysates with high inhibitors concentration, promoting the implementation of lignocellulosic biorefineries.
