Motivation: Genetic and gene expression variations within and between populations and across geographical regions have substantial effects on the biological phenotypes, diseases, and therapeutic response. The development of precision medicines can be facilitated by the OMICS studies of the patients of specific ethnicity and geographic region. However, there is an inadequate facility for broadly and conveniently accessing the ethnic and regional specific OMICS data. Results: Here, we introduced a new free database, HEROD, a human ethnic and regional specific OMICS database...

Human childbirth has been described as an "obstetrical dilemma". Evolution favours enlargement of the foetal brain, whilst bipedal locomotion demands a reduction in pelvic breadth for improvements in biomechanical efficiency. The result of this conflict is a human pelvis incongruous with the dynamics of childbirth. Acute genital distortion at delivery can inflict lasting damage to female pelvic function. Pelvic organ prolapse, urinary, faecal incontinence and sexual dysfunction are long-term sequelae rarely discussed at antenatal care, impacting upon the expectant mother's ability to make an informed decision...

Over recent years there has been an increased emphasis on improving patient safety in all branches of medicine, with reducing wrong tooth extraction being a priority in dentistry. The true incidence of wrong tooth extraction is unknown but it is considered an avoidable harm and is a significant source of dental litigation. Interventions to reduce wrong tooth extraction include educational programmes encompassing human factor training, patient assisted identification, the use of checklists, marking of surgical sites and implementation of patient safety guidelines...

Primary Biliary Cholangitis, previously known as Primary Biliary Cirrhosis, is a rare disease, which mainly affects women in their fifth to seventh decades of life. It is a chronic autoimmune disease characterized by a progressive damage of interlobular bile ducts leading to ductopenia, chronic cholestasis and bile acids retention. Even if the disease usually presents a long asymptomatic phase and a slow progression, in many patients it may progress faster toward cirrhosis and its complications. The 10year mortality is greater than in diseases such as human immunodeficiency virus/Hepatitis C Virus coinfection and breast cancer...

In November 2015, the first plasmid-encoded colistin resistance gene, mcr-1, was described in animals and in humans in China. Subsequently, a multitude of further studies was performed and quite recently the global spread of mcr-1 as well as the occurrence of a new gene variant, mcr-2, was reported. To obtain an overview of the occurrence of the colistin resistance genes mcr-1 and mcr-2 in German pig farms, a retrospective study, including 436 boot swab and pooled faeces samples collected from 58 pig-fattening farms throughout Germany, was performed...

Placenta-derived mesenchymal stromal cells (MSC) have often been considered to linger behind their equivalents from other tissues, such as MSC from bone marrow, in many aspects including their therapeutic potential in regenerative medicine. Nowadays however, it is clear that certain aspects make placental MSC attractive as a cellular therapy, such as their lack of ethical concerns and ease of isolation from human term placenta, a material long regarded as biological waste. Moreover, placental MSC virtually lack expression of human leukocyte antigens and co-stimulatory molecules, making them very attractive for transplantation in allogeneic settings...

Artificial intelligence (AI) is a field of computer science that aims to mimic human thought processes, learning capacity, and knowledge storage. AI techniques have been applied in cardiovascular medicine to explore novel genotypes and phenotypes in existing diseases, improve the quality of patient care, enable cost-effectiveness, and reduce readmission and mortality rates. Over the past decade, several machine-learning techniques have been used for cardiovascular disease diagnosis and prediction. Each problem requires some degree of understanding of the problem, in terms of cardiovascular medicine and statistics, to apply the optimal machine-learning algorithm...

BACKGROUND: In the current context of personalized medicine, one of the major challenges in the management of rheumatoid arthritis (RA) is to identify biomarkers that predict drug responsiveness. From the European APPRAISE trial, our main objective was to identify a gene expression profile associated with responsiveness to abatacept (ABA) + methotrexate (MTX) and to understand the involvement of this signature in the pathophysiology of RA. METHODS: Whole human genome microarrays (4 × 44 K) were performed from a first subset of 36 patients with RA...

Cell therapies using human mesenchymal stem cells (MSCs) have received much attention in the past decade. In pursuit of the therapeutic potential of MSCs, cell expansion is required to generate a great number of cells with desired phenotype and functionality. Long-term expansion in vitro, however, can lead to altered functions. To explore the changes in DNA damage responses (DDR) in MSCs expanded, DDR pathways following irradiation were characterized in early- and late-passage bone marrow MSCs. Seventy-two hours after irradiation, the percentage of sub-G1 cells in early-passage MSCs did not change significantly...

The ability to create 3D tissues from induced pluripotent stem cells (iPSCs) is poised to revolutionize stem cell research and regenerative medicine, including individualized, patient-specific stem cell-based treatments. There are, however, few examples of tissue engineering using iPSCs. Their culture and differentiation is predominantly planar for monolayer cell support or induction of self-organizing embryoids (EBs) and organoids. Bioprinting iPSCs with advanced biomaterials promises to augment efforts to develop 3D tissues, ideally comprising direct-write printing of cells for encapsulation, proliferation, and differentiation...

Compounds containing nitrogen and sulfur atoms can be widely used in various fields, including industry, medicine, biotechnology, and chemical technology. Among them, amides of acids and heterocyclic compounds have an important place. These amides and thiazolidine-4-ones showed good inhibitory action against butyrylcholinesterase (BChE), acetylcholinesterase (AChE), and human carbonic anhydrase isoforms. AChE exists at high concentrations in the brain and red blood cells. BChE is an important enzyme that is plentiful in the liver, and it is released into the blood in a soluble form...

Sentinel lymph node evaluation is widely used in human medicine to evaluate the first lymph node(s) to which a tumor drains. Sentinel lymph node biopsy allows avoidance of extensive lymphadenectomies in cases where the sentinel lymph node is negative for metastasis, thereby reducing patient morbidity. It has been shown that regional lymph nodes are not always the sentinel lymph node, thus identification and sampling of sentinel lymph nodes allows for more accurate staging, which is critical for treatment and prognostication in dogs with cancer...

In the forty-year history of U.S. bioethics commissions, these government-sanctioned forums have often demonstrated their power to address pressing problems and to enable policy change. For example, the National Commission for the Protection of Human Subjects of Biomedical and Behavioral Research, established in 1974, left a legacy of reports that were translated into regulations and had an enormous practical impact. And the 1982 report Splicing Life, by the President's Commission for the Study of Ethical Problems in Medicine and Biomedical and Behavioral Research, became the basis for the National Institutes of Health's Recombinant DNA Advisory Committee as well as for the Food and Drug Administration's developing "Points to Consider" when contemplating the introduction of recombinant DNA into human beings...

This issue of the Hastings Center Report (May-June 2017) features a couple of interesting takes on the governance challenges of emerging technologies. In an essay on the National Academies of Science, Engineering, and Medicine report published this February on human germ-line gene editing, Eric Juengst, a philosopher at the University of North Carolina, argues that the NASEM committee did not manage to rethink the rules. Juengst reaches what he calls an "eccentric conclusion": "The committee's 2017 consensus report has been widely interpreted as 'opening the door' to inheritable human genetic modification and holding a line against enhancement interventions...

In 2015, a flourish of "alarums and excursions" by the scientific community propelled CRISPR/Cas9 and other new gene-editing techniques into public attention. At issue were two kinds of potential gene-editing experiments in humans: those making inheritable germ-line modifications and those designed to enhance human traits beyond what is necessary for health and healing. The scientific consensus seemed to be that while research to develop safe and effective human gene editing should continue, society's moral uncertainties about these two kinds of experiments needed to be better resolved before clinical trials of either type should be attempted...
