CONTEXT: In the UK, applications to medicine from those in lower socio-economic groups remain low despite significant investments of time, interest and resources in widening access (WA) to medicine. This suggests that medical schools' core messages about WA may be working to embed or further reinforce marginalisation, rather than to combat this. Our objective was to investigate how the value of WA is communicated by UK medical schools through their websites, and how this may create expectations regarding who is 'suitable' for medicine...

BACKGROUND: Current tuberculosis regimens have failed to combat the issue of drug resistance and ethno medicines may represent a possible source of antimycobacterial agents. Combretum species are well known in African traditional medicines and used for various ailments including pneumonia, venereal diseases like syphilis, mental problems, relief of sore throats and colds, fever, and chest coughs associated with tuberculosis. Alkaloids function as either hydrogen-acceptor or hydrogen-donor in hydrogen bonding critical for the interaction between targets thus, potentiating effects of curative agents on diseases...

Obesity is a heritable trait that contributes to substantial global morbidity and mortality. Here, we summarize findings from the last decade of genetic and epigenetic research focused on unravelling the underpinnings of adiposity. More than 140 genetic regions are now known to influence adiposity traits. The genetics of general adiposity, as measured by body mass index, and that of abdominal obesity, as measured by waist to hip ratio, have distinct biological backgrounds. Expression of genes associated with general adiposity are enriched in the nervous system...

Despite the worldwide research efforts to combat cancer, it remains a leading cause of death. Although various specific kinase inhibitors already have been approved for clinical cancer treatment, occurrence of intrinsic or acquired resistance and intermittent response over longer periods limits long-term success of single kinase-targeted therapies. In this respect, there is a renewed interest in polypharmaceutical natural compounds, which simultaneously target various hyperactivated kinases involved in tumour-inflammation, angiogenesis, cell survival, proliferation, metastasis and angiogenesis...

Psidium guajava is a Myrtaceae plant whose medicinal properties are recognized in several locations. The use of teas and tinctures prepared from their leaves has been used to combat infections caused by fungi of the genus Candida. In this study, aqueous extracts of leaves and hydroethanolic were tested to verify the antifungal potential and its chemical composition has been investigated. The microbiological assays were performed by broth microdilution to determine the minimum inhibitory concentration (MIC) and from these the minimum fungicidal concentration was performed (MFC) by subculturing on solid media...

The leaves of Lannea coromandelica (Houtt.) Merr. are used in the Garo, Pahan, and Teli tribal communities of Bangladesh as a traditional medicinal plant to treat hepatitis, diabetes, ulcers, heart disease, and dysentery. However, there have been limited phytochemical and biological studies on the bark of L. coromandelica. This study aimed to investigate the antioxidant activities of L. coromandelica bark extract (LCBE) and the underlying mechanism using RAW 264.7 cells. The LCBE was analysed by high-pressure liquid chromatography (HPLC) to detect its key polyphenolic compounds...

: Anaplastic lymphoma kinase (ALK) is a validated molecular target in several ALK-rearranged malignancies, including non-small cell lung cancer. However, the clinical benefit of targeting ALK using tyrosine kinase inhibitors (TKI) is almost universally limited by the emergence of drug resistance. Diverse mechanisms of resistance to ALK TKIs have now been discovered, and these basic mechanisms are informing the development of novel therapeutic strategies to overcome resistance in the clinic...

The quality of medical literature is increasingly threatened by irresponsible publishing, leading to rising retraction rates, irreproducible results, and a flood of inconsequential publications that distract readers from more meaningful scholarship. "Predatory publishers" offer rapid publication with loose peer review, exploiting a system in which faculty seek longer bibliographies to achieve academic promotion. In this Commentary, the authors highlight some of the evidence that this problem exists and suggest actions to address it...

An important focus of modern medicine is the search for new substances and strategies to combat infectious diseases, which present an increasing threat due to the growth of bacterial resistance to antibiotics. Another problem concerns free radicals, which in excess can cause several serious diseases. An alternative to chemical synthesis of antimicrobial and antiradical compounds is to find active substances in plant raw materials. We prepared extracts from leaves of five species of the genus Bergenia: B. purpurascens, B...

BACKGROUND: Antipsychotic-related constipation is a common and serious adverse effect, especially for people taking clozapine. Clozapine has been shown to impede gastrointestinal motility, leading to constipation, and has been reported in up to 60% of patients receiving clozapine. In rare cases, complications can be fatal. Appropriate laxatives should be prescribed to treat constipation in people taking antipsychotics, but there is a lack of guidance on the comparative effectiveness and harms of different agents in this population...

: Bacteriophages infect an estimated 10(23) to 10(25) bacterial cells each second, many of which carry physiologically relevant plasmids (e.g., those encoding antibiotic resistance). However, even though phage-plasmid interactions occur on a massive scale and have potentially significant evolutionary, ecological, and biomedical implications, plasmid fate upon phage infection and lysis has not been investigated to date. Here we show that a subset of the natural lytic phage population, which we dub "superspreaders," releases substantial amounts of intact, transformable plasmid DNA upon lysis, thereby promoting horizontal gene transfer by transformation...

Hepatitis C virus (HCV) is a serious global health problem affecting approximately 130-150 million individuals. Presently available direct-acting anti-HCV drugs have higher barriers to resistance and also improved success rate; however, cost concerns limit their utilization, especially in developing countries like India. Therefore, development of additional agents to combat HCV infection is needed. In the present study, we have evaluated anti-HCV potential of water, chloroform, and methanol extracts from roots of Valeriana wallichii, a traditional Indian medicinal plant...

BACKGROUND: The availability of effective antibiotics is considered one of the most important developments in medicine. However, many organisms that were once susceptible to common antibiotics are becoming resistant. Antimicrobial stewardship programs (ASPs) are considered to be vital for combating the emergence of resistance. To understand current antimicrobial stewardship practices in Kansas, the authors designed a 36-question survey. Results of this survey will be used to develop a coordinated, public health strategy for improving current practices...

Studies involving adoptive families and twins have demonstrated the genetic basis of hypertension and shown that genetic factors account for about 40% of the variance in blood pressure among individuals. Arterial hypertension is genetically complex: multiple genes influence the blood pressure phenotype through allelic effects from single genes and gene-gene interactions. Moreover, environmental factors also modify the blood pressure phenotype. This complexity explains why the identification of the underlying genes has not been as successful in hypertension as in other diseases (such as type 1 and type 2 diabetes mellitus)...

The ETS-related transcription factor Fli-1 affects many developmental programs including erythroid and megakaryocytic differentiation, and is frequently de-regulated in cancer. Fli-1 was initially isolated following retrovirus insertional mutagenesis screens for leukemic initiator genes, and accordingly, inhibition of this transcription factor can suppress leukemia through induction of erythroid differentiation. To search for modulators of Fli-1, we hereby performed repurposing drug screens with compounds isolated from Chinese medicinal plants...
