Gastrointestinal nematode (GIN) infestations are a major constraint to sheep production in the West Indies (WI). Intensive and semi-intensive management systems are most commonly employed. These islands display tropical weather patterns with wet and dry seasons. Semi-intensive farming combined with increased rainfall during the wet season has been reported to be most favourable for development and survival of GIN. This study was conducted to determine whether there was a relationship between GIN burdens in sheep with seasonality and management practices of farmers in Trinidad and Tobago (T&T). Farms were visited on a monthly basis from January to December 2017. A maximum of ten sheep, three to nine months of age, were selected from each farm. A total of 3,053 faecal samples were collected and analysed using the Modified McMaster technique. Environmental data on daily precipitation and temperature were collected from the Trinidad and Tobago Meteorological Office during the period of sampling. A mixed effects nlopment and distribution year-round. Proper management is therefore required for reducing the occurrence of GIN in sheep of T&T throughout the year. This is the first reported study in the WI on the influence of seasonality and management on GIN infestations in sheep during the dry and wet seasons. Further investigation is needed to elucidate why GIN burdens appear to be higher in the dry season than the wet season. This study can be used as a baseline for public education in T&T as well as other developing countries. © 2020 Blackwell Verlag GmbH.Esophageal squamous cell carcinoma (ESCC) is one of the most common malignant tumors around the world. Numerous studies have revealed the function of long non-coding RNAs (lncRNAs) in cancers, including ESCC. In this study, lncRNA small nucleolar RNA host gene 12 (SNHG12), mainly distributed in ESCC cell cytoplasm, was overexpressed in ESCC specimens and CD133+ cells. In CD133- ESCC cells, SNHG12 overexpression promoted cell proliferation, migration, epithelial-mesenchymal transition (EMT) and stemness and SNHG12 silencing led to opposite results. Furthermore, SNHG12 sequestered miR-6835-3p and induced the proto-oncogene, polycomb ring finger (BMI1). SNHG12 also enhanced the stability of CTNNB1, the mRNA encoding β-catenin, via recruiting insulin-like growth factor 2 mRNA-binding protein 2 (IGF2BP2) in ESCC. Rescue assays indicated that CTNNB1 and BMI1 were targets for SNHG12 to regulate ESCC cell proliferation, migration, EMT and stemness. Furthermore, SOX4 (sex-determining region Y-box 4) bound with the SNHG12 promoter to transcriptionally activate SNHG12 in ESCC. Finally, in vivo data showed SNHG12 knockdown retarded tumorigenesis and metastasis in ESCC. In summary, SNHG12 induces proliferation, migration, EMT and stemness of ESCC cells via post-transcriptional regulation of BMI1 and CTNNB1, indicating that targeting SNHG12 might be a novel target for ESCC treatment.

Here, a recombinant E2 (rE2) protein and a peroxidase-conjugated monoclonal antibody (MAb G5) were used to develop a competition-based chemiluminescence immunoassay (cCLIA) for rapid and accurate detection of E2-specific antibodies in pig serum. To evaluate the feasibility of cCLIA in the diagnosis of CSF, we developed a competition-based enzyme-linked immunosorbent assay (cELISA) as a control. Under the optimum test conditions, cCLIA showed a higher signal-to-noise ratio than that of the control cELISA. The best signal-to-noise ratios of cCLIA and cELISA were 70 and 17, respectively. Then, the diagnostic performance of the two assays was compared by examining a panel of pig serum samples (n=285) with a confirmed status, and cCLIA showed higher diagnostic sensitivity (Dn) and diagnostic specificity (Dp) values than those of cELISA. The Dn and Dp of cCLIA were 97.49% and 96.08%, respectively, and those of cELISA were 93.97% and 94.12%, respectively. Furthermore, cCLIA can provide results within 20 min, whereas the control cELISA requires at least 1 h. According to these findings, the newly developed cCLIA has potential application in the diagnosis of CSF and offers an alternative approach for efficient and rapid detection of E2-specific antibodies.

Recently, alternative cell death pathways have emerged whose regulation is dependent on proteins with canonical functions in apoptosis. Dysregulation of apoptotic signaling frequently underlies the pathogenesis of many cancers, reinforcing the need to develop therapies that initiate alternative cell death processes. This review outlines the convergence points between apoptosis and other death pathways with the purpose of identifying novel strategies for the treatment of apoptosis-refractory cancers. Apoptosis proteins can play key roles in the initiation, regulation, and execution of nonapoptotic death processes that include necroptosis, autophagy, pyroptosis, mPTP-mediated necrosis, and ferroptosis. Nutlin-3a Notably, recent evidence illustrates that dying cells can exhibit biochemical and molecular characteristics of more than one different type of regulated cell death. Thus, this review highlights the amazing complexity and interconnectivity of cell death processes and also raises the idea that a top-to-bottom approach to describing cell death mechanisms may be inadequate for fully understanding the means by which cells die. © 2020 Federation of European Biochemical Societies.As agonists of TLR7/8, single-stranded RNAs (ssRNAs) are safe and promising adjuvants that do not cause off-target effects or innate immune overactivation; however, low stability prevents them from mounting sufficient immune responses. This study aimed to evaluate the adjuvant effects of ssRNA derived from the cricket paralysis virus intergenic region internal ribosome entry site, formulated as nanoparticles with a coordinative amphiphile, containing a zinc/dipicolylamine complex moiety as a coordinative phosphate binder. We applied our amphiphile system as a stabilizer for RNA-based adjuvants. The nanoformulated ssRNA-based adjuvant was resistant to enzymatic degradation in vitro and in vivo. The ssRNA-based adjuvant formulated with a coordinative amphiphile bearing an oleyl group (CA-O) was approximately100 nm, promoted effective recognition and improved activation of antigen-presenting cells, leading to better induction of neutralizing antibodies following single immunization. Hence, CA-O may increase the efficacy of ssRNA-based adjuvants, proving useful to meet the urgent need for vaccines during pathogen outbreaks.
