Multiplex families with type 1 diabetes are important for identification of rare variants that cannot be identified in case-control association studies. Very low incidence of type 1 diabetes in Japanese population, however, makes identification of such families difficult. We identified a Japanese family in which three members developed type 1 diabetes, and studied the genotype of the HLA. All three members with type 1 diabetes had the DRB1*08:02-DQB1*03:02 haplotype, which is specific to the Asian population and strongly susceptible for type 1 diabetes...

Proteasomes are multisubunit protease complexes responsible for degrading most intracellular proteins. In addition to removing damaged proteins, they regulate many important cellular processes through the controlled degradation of transcription factors, cell cycle regulators and enzymes. Eukaryotic proteasomes have three catalytic subunits, β1, β2 and β5, that each have different substrate specificities. Additionally, although we know that diverse cell types express proteasome variants with distinct activity and specificity profiles, the functions of these different pools of proteasomes are not fully understood...

BACKGROUND AND AIMS: Beta-caryophyllene (BCP) is a plant-derived FDA approved food additive with anti-inflammatory properties. Some of its beneficial effects in vivo reported to involve activation of cannabinoid 2 receptors (CB2) that are predominantly expressed in immune cells. Herein, we evaluated the translational potential of BCP using a well-established model of chronic and binge alcohol-induced liver injury. METHODS: In this study we investigated the effects of BCP on liver injury induced by chronic plus binge alcohol feeding in mice in vivo by using biochemical assays, real-time PCR and histology analyses...

Shrub densification has been widely reported across the circumpolar arctic and subarctic biomes in recent years. Long-term analyses based on dendrochronological techniques applied to shrubs have linked this phenomenon to climate change. However, the multi-stemmed structure of shrubs makes them difficult to sample and therefore leads to non-uniform sampling protocols among shrub ecologists, who will favor either root collars or stems to conduct dendrochronological analyses. Through a comparative study of the use of root collars and stems of Betula glandulosa, a common North American shrub species, we evaluated the relative sensitivity of each plant part to climate variables, and assessed if this sensitivity is consistent across three different types of environments in northwestern Québec, Canada (terrace, hilltop and snowbed)...

Background and aims Precut papillotomy is widely used after failed biliary cannulation. Endoscopic ultrasound (EUS)-guided biliary access techniques are newer methods to facilitate access and therapy in failed cannulation. We evaluated the impact of EUS-guided biliary access on endoscopic retrograde cholangiopancreatography (ERCP) success and compared these techniques to precut papillotomy. Patients and methods We retrospectively compared two ERCP cohorts. One cohort consisted of biliary ERCPs (n = 1053) attempted in patients with native papillae and surgically unaltered anatomy in whom precut papillotomy and/or EUS-guided biliary access were routinely performed immediately after failed cannulation...

: Background and study aims (Virtual) chromoendoscopy detects more polyps than standard white-light endoscopy in patients with Lynch syndrome. Previous back-to-back trials did not randomize for the examination order, creating a possible bias in favor of chromoendoscopy. We aimed to assess the difference in polyp detection between high definition white-light endoscopy (HD-WLE) and virtual chromoendoscopy with I-SCAN in patients with Lynch syndrome. Patients and methods In this prospective, controlled trial, patients were randomized to either HD-WLE followed by I-SCAN (Group 1; n = 31) or I-SCAN followed by HD-WLE (Group 2; n = 30)...

Lamina-associated domains (LADs) are large genomic regions that interact with the nuclear lamina (NL) and help to guide the spatial folding of chromosomes in the interphase nucleus. LADs have been linked to gene repression and other functions. Recent studies have begun to uncover some of the molecular players that drive LAD-NL interactions. A picture emerges in which DNA sequence, chromatin components and nuclear lamina proteins play an important role. Complementary to this, imaging and single-cell genomics approaches have revealed that some LAD-NL interactions are variable from cell to cell, while others are very stable...

To develop more potent JAK3 kinase inhibitors, a series of CP-690550 derivatives were investigated using combined molecular modeling techniques, such as 3D-QSAR, molecular docking and molecular dynamics (MD). The leave-one-out correlation (q(2)) and non-cross-validated correlation coefficient (r(2)) of the best CoMFA model are 0.715 and 0.992, respectively. The q(2) and r(2) values of the best CoMSIA model are 0.739 and 0.995, respectively. The steric, electrostatic, and hydrophobic fields played important roles in determining the inhibitory activity of CP-690550 derivatives...

Malaria, schistosomiasis and leishmaniases are among the most prevalent tropical parasitic diseases and each requires new innovative treatments. Targeting essential parasite pathways, such as those that regulate gene expression and cell cycle progression, is a key strategy for discovering new drug leads. In this study, four clinically approved anti-cancer drugs (Vorinostat, Belinostat, Panobinostat and Romidepsin) that target histone/lysine deacetylase enzymes were examined for in vitro activity against Plasmodium knowlesi, Schistosoma mansoni, Leishmania amazonensis and L...
