The small Rab GTPases are key regulators of membrane vesicle trafficking. Ovaries of Periplaneta americana (Linnaeus) (Blattodea: Blattidae) have small molecular weight GTP/ATP-binding proteins during early and late vitellogenic periods of oogenesis. However, the identification and characterization of the detected proteins have not been yet reported. Herein, we cloned a cDNA encoding Rab5 from the American cockroach, P. americana, ovaries (PamRab5). It comprises 796 bp, encoding a protein of 213 amino acid residues with a predicted molecular weight of 23...

PAX binding protein 1 (PAXBP1) is an adaptor protein linking the transcription factor PAX3 and PAX7 to the histone methylation machinery. PAXBP1 is a nuclear protein and its high expression is known in brain cerebellar hemisphere and cerebellum. Moreover, it is also found in abundance in muscle precursor cells that are involved in myogenesis and skeletal muscles formation. Whole genome SNP genotyping and exome sequencing in a family with distinct syndrome of global developmental delay and hypotonia mapped the disease locus to the chromosome 21q22...

Antimicrobial agents are used in cattle production systems for the prevention and control of bacterial associated diseases. A consequence of their use is the potential development of antimicrobial resistance (AMR). Enterococcus faecium and Enterococcus faecalis that are resistant to antimicrobials are of increased concern to public health officials throughout the world as they may compromise the ability of various treatment regimens to control disease and infection in human medicine. Australia is a major exporter of beef; however it does not have an ongoing surveillance system for AMR in cattle or foods derived from these animals...

The world is in the midst of a pre-emptive public health emergency, one that is just as dramatic as the global aggressive viruses-related crises (Ebola, Zika, or SARS), but not as visible. The "superbugs" and their antimicrobial resistance (AMR) don't cause much public alarm or awareness, but provoke financial losses of $100 trillion annually [1] . This status quo review offers an overview of ultrasensitive methods for high-throughput monitoring of bacteria during infection treatment, the effects of antibiotics on bacteria at single-cell level and the challenges we will need to face in their detection due to the extraordinary capability of these "superbugs" to gain and constantly improve multiresistance to antibiotics...

Globally, rates of ESBL-producing Enterobacteriaceae are rising. We undertook a literature review, and present the temporal trends in blaCTX-M epidemiology, showing that blaCTX-M-15 and blaCTX-M-14 have displaced other genotypes in many parts of the world. Explanations for these changes can be attributed to: (i) horizontal gene transfer (HGT) of plasmids; (ii) successful Escherichia coli clones; (iii) ESBLs in food animals; (iv) the natural environment; and (v) human migration and access to basic sanitation...

In patients whom are highly sensitized immunologically, the benefit of kidney transplantation can be extended to this population through the utilization of organs from human leukocyte antigen incompatible (HLAi) donors. This retrospective observational study was designed to identify the incidence and predictors of acute antibody-mediated rejection/acute cellular rejection (AMR/ACR) in our kidney recipients from living kidney donors (sensitized and those with low immunologic risk). This single-center study has been conducted at King Fahad Specialist Hospital, Dammam (KFSH-D), Saudi Arabia; during the period of September 2008- August 2013...

Acute antibody-mediated rejection (AMR) remains an important challenge in the field of kidney transplantation despite the advances in immunosuppressive strategies, and has been recognized as an important cause of allograft dysfunction and graft loss. The treatments of acute AMR are not standardized and poor evidence is currently available on the effectiveness of therapy regimens with combinations of drugs. Standard treatment for acute AMR is based on 3 cornerstones: removal of donor-specific antibodies (DSAs) from the bloodstream, reduction of DSAs synthesis, and inhibition of the interaction between DSAs and human leukocyte antigen antigens on donor's cells...

G-protein-coupled receptors (GPCRs) are shown to be involved in Alzheimer's disease (AD) pathogenesis. However, because GPCRs include a large family of membrane receptors, it is unclear which specific GPCR or pathway with rational ligands can become effective therapeutic targets for AD. Amylin receptor (AmR) is a GPCR that mediates several activities, such as improving glucose metabolism, relaxing cerebrovascular structure, modulating inflammatory reactions and potentially enhancing neural regeneration. Recent studies show that peripheral treatments with amylin or its clinical analog, pramlintide, reduced several components of AD pathology, including amyloid plaques, tauopathy, neuroinflammation and other components in the brain, corresponding with improved learning and memory in AD mouse models...

In recent years, the antimicrobial resistance (AMR) or multidrug resistance (MDR) has become a serious health concern and major challenging issue, worldwide. After decades of negligence, the AMR has now captured global attention. The increasing number of antibiotic-resistant strains has threatened the achievements of science and medicine since it inactivates conventional antimicrobial therapeutics. Scientists are trying to respond to AMR/MDR threat by exploring innovative platforms and new therapeutic strategies to tackle infections from these resistant strains and bypass treatment limitations related to these pathologies...

With unknown etiology, scleroderma (SSc) is a multifaceted disease characterized by immune activation, vascular complications, and excessive fibrosis in internal organs. Genetic studies, including candidate gene association studies, genome-wide association studies, and whole-exome sequencing have supported the notion that while genetic susceptibility to SSc appears to be modest, SSc patients are genetically predisposed to this disease. The strongest genetic association for SSc lies within the MHC region, with loci in HLA-DRB1, HLA-DQB1, HLA-DPB1, and HLA-DOA1 being the most replicated...

BACKGROUND: Ethiopia set an ambitious masterplan to increase chicken meat and egg production from 2015 to 2020. Poultry breeding, multiplication and distribution centers in the country have received executive order to import, amplify and distribute commercial chickens to end users. The biosecurity and the pathogen fauna of the centers have not been evaluated as to whether the centers could implement the mission effectively without any risk. Thus, the aim of this study was to evaluate the biosecurity practices and the pathogen prevalence, risk factors and their antimicrobial resistance (AMR) using Salmonella as case study...

The causes of antimicrobial resistance (AMR) in developing countries are complex and may be rooted in practices of health care professionals and patients' behavior towards the use of antimicrobials as well as supply chains of antimicrobials in the population. Some of these factors may include inappropriate prescription practices, inadequate patient education, limited diagnostic facilities, unauthorized sale of antimicrobials, lack of appropriate functioning drug regulatory mechanisms, and non-human use of antimicrobials such as in animal production...

In Asian countries, concomitant splenectomy in living donor liver transplantation (LDLT) is indicated to modulate the portal vein pressure in the small sized graft to protect against small for size syndrome. While concomitant splenectomy in deceased donor liver transplantation is almost contraindicated based on western reports of increased mortality and morbidity rate due to septic complications, there are few studies about that in LDLT. So, we retrospectively investigated the clinical outcome of adult LDLT at Kyoto University Hospital from July 2010 to July 2016...
