In Sub-Saharan Africa, high clinical demand for transfusion faces endemic bloodborne infections and limited resources. Blood screening for transfusion-transmitted bloodborne pathogens is the cornerstone of blood safety. Although there have been substantial improvements over the years, challenges in transfusion-transmitted infection screening that have been identified repeatedly long ago still need to be addressed. Affordability and sustainability of state-of-the-art quality assessed serological and molecular assays, and associated confirmation strategies remain of real concern. In addition, limited resources and infrastructures hamper the development of adequate facilities, quality management, and staff qualification, and exacerbate shortage of reagents and equipment maintenance. It is also important to maintain effort in constituting pools of repeat voluntary non-remunerated donors. Alternative strategies for blood screening that take into account local circumstances might be desirable but they should rely on appropriate field evaluation and careful economic assessment rather than dogma established from high-resource settings.Haemophilia care remains challenging especially in resource-limited settings where haemophilia and other non-communicable diseases may not be considered a healthcare priority, in comparison to malaria, HIV/AIDS and other infectious diseases. This article is a review of the evolution in haemophilia care in Africa, with focus on countries with varying degrees of care (Cameroon with budding care; Senegal with more evolved care and Egypt with a more longstanding history of care). The indispensable role of the World Federation of Haemophilia is highlighted in all the contexts of care.

Traditional Chinese medicine manipulation (TCMM) is often used to treat human skeletal muscle injury, but its mechanism remains unclear due to difficulty standardizing and quantifying manipulation parameters.

Here, dexamethasone sodium phosphate (DSP) was utilized to induce human skeletal muscle cell (HSkMC) impairments. Cells in a three-dimensional environment were divided into the control normal group (CNG), control injured group (CIG) and rolling manipulation group (RMG). The RMG was exposed to intermittent pressure imitating rolling manipulation (IPIRM) of TCMM via the FX‑5000™ compression system. Skeletal muscle damage was assessed via the cell proliferation rate, superoxide dismutase (SOD) activity, malondialdehyde (MDA) content and creatine kinase (CK) activity. Isobaric tagging for relative and absolute protein quantification (iTRAQ) and bioinformatic analysis were used to evaluate differentially expressed proteins (DEPs).

Higher-pressure IPIRM ameliorated the skeletal muscle cell injury induceds study might provide novel insights into the mechanism of TCMM.Enterococcal plasmids have generated renewed interest for their indispensable role in pathogenesis and dissemination of multidrug-resistance. Recently, a novel plasmid pSM409 (4303-bp, GC% = 33.6%), devoid of antibiotic-resistance and virulence genes, has been identified in Enterococcus faecium RME, isolated from raw milk by us. pSM409 contains six open reading frames encoding a replication initiator protein (RepB) and five accessory proteins antitoxin epsilon, bacteriocin immunity protein, HsdS, and two hypothetical proteins. Comparative sequence analysis of pSM409 reveals a mosaic pattern of similarity with different loci obtained from different theta plasmids, which dictates the plasmid to be heterogeneous or mosaic, possibly due to recombination. The pSM409 comprised of a typical theta-type origin of replication with four and a half direct repeats (iterons) of 22 nucleotides. The pSM409-RepB shared 76-82% homology with the RepB of reported theta plasmids from different genera, with dissimilarities mostly in its DNA-binding and C-terminal domain. The RepB sequence-based phylogenetic tree revealed its distinct position relative to the reported ones. The RepB grouped in the same clade has identical DNA-binding domains and their cognate iterons, possibly due to their sequence-specific interaction to initiate plasmid replication. Comparative analysis of the pSM409-iteron reveals that the repeats markedly differed from their closest homologues. This clade-specific relationship provides a new concept of classifying theta plasmids. The theta-type replicon identified in pSM409 has been found to be unique to E. faecium RME, prompting us to further investigate its utility as a vector for genetic manipulation of enterococci for health and industry.A universal phenomenon of using synonymous codons unequally in coding sequences known as codon usage bias (CUB) is observed in all forms of life. Mutation and natural selection drive CUB in many species but the relative role of evolutionary forces varies across species, genes and genomes. We studied the CUB in mitochondrial (mt) CO genes from three orders of Amphibia using bioinformatics approach as no work was reported yet. We observed that CUB of mt CO genes of Amphibians was weak across different orders. Order Caudata had higher CUB followed by Gymnophiona and Anura for all genes and CUB also varied across genes. Nucleotide composition analysis showed that CO genes were AT-rich. The AT content in Caudata was higher than that in Gymnophiona while Anura showed the least content. Multiple investigations namely nucleotide composition, correspondence analysis, parity plot analysis showed that the interplay of mutation pressure and natural selection caused CUB in these genes. Neutrality plot suggested the involvement of natural selection was more than the mutation pressure. VDA chemical The contribution of natural selection was higher in Anura than Gymnophiona and the lowest in Caudata. The codons CGA, TGA, AAA were found to be highly favoured by nature across all genes and orders.RBM10 is a nuclear RNA-binding protein (RBP) that regulates the alternative splicing of primary transcripts. Recently, research on RBM10 has become increasingly active owing to its clinical importance, as indicated by studies on RBM0 mutations that cause TARP syndrome, an X-linked congenital pleiotropic developmental anomaly, and various cancers such as lung adenocarcinoma in adults. Herein, the molecular biology of RBM10 and its significance in medicine are reviewed, focusing on the gene and protein structures of RBM10, its cell biology, molecular functions and regulation, relationship with the paralogous protein RBM5, and the mutations of RBM10 and their associated diseases. Finally, the challenges in future studies of RBM10 are discussed in the concluding remarks.
