BACKGROUND: Aberrantly expressed microRNAs (miR) promote renal cell carcinoma (RCC) growth and metastasis and are potentially useful biomarkers for metastatic disease. However, a consensus clinically significant miRNA signature has not been identified. To identify a miRNA signature for predicting clinical outcome in RCC patients we used a four-pronged interconnected approach. METHODS: Differentially expressed miRs were identified and analyzed in 113 specimens (Normal kidney: 59; tumor: 54)...

Anxiety disorders are chronic and functionally disabling conditions with high psychological stress, characterised by cognitive symptoms of excessive worry and focus difficulties and physiological symptoms such as muscle tension and insomnia. Gamma-aminobutyric acid (GABA) is an inhibitory neurotransmitter within the central nervous system and is a key target of pharmacotherapies in the treatment of anxiety. Although current pharmaceutical treatments are often efficacious, they may cause undesirable side effects including cognitive decrements and withdrawal symptoms...

The presence of adducts on the DNA double-helix can have major consequences for the efficient functioning of DNA repair enzymes. E. coli RecBCD (exonuclease V) is involved in recombinational repair of double-strand breaks that are caused by defective DNA replication, DNA damaging agents and other factors. The holoenzyme possesses a bipolar helicase activity which helps unwind DNA from both 3'- and 5'-directions and is coupled with a potent exonuclease activity that is also capable of digesting DNA from both 3'- and 5'-ends...

Objective: While the incidence of sarcoidosis peaks between 20 and 39 years, it is comparatively low in elderly subjects. We sought to determine whether there are age-dependent differences in the demographic and laboratory characteristics of patients with sarcoidosis. Materials and Methods: We retrospectively collected information from our database using the International Classification of Disease (ICD) diagnostic code D86 between 2008 and 2014. Patients were divided into three groups: 20-39 years old (Group 1), 40-59 years old (Group 2), and 60-80 years old (Group 3)...

Melioidosis is a tropical disease caused by the bacterium Burkholderia pseudomallei. Outbreaks are uncommon and can generally be attributed to a single point source and strain. We used whole-genome sequencing to analyse B. pseudomallei isolates collected from an historical 2-year long case cluster that occurred in a remote northern Australian indigenous island community, where infections were previously linked to a contaminated communal water supply. We analysed the genome-wide relatedness of the two most common multilocus sequence types (STs) involved in the outbreak, STs 125 and 126...

Consumption of kava (Piper methysticum Forst) has been linked to reduced cancer risk in the South Pacific Islands. Kavalactones are major bioactive components in kava root extracts, which have recently demonstrated anti-cancer activities. However, molecular mechanisms of kavalactones' anti-cancer action remain largely unknown. We have identified two kavalactones, yangonin and 5' 6'-dehydrokawain, as potent inducers of autophagic cell death in bladder cancer cells. The effect of yangonin inducing autophagy is associated with increased expression of beclin and ATG5...

The effect of increasing donor body mass index (BMI) on clinical pregnancies was retrospectively analysed in a cohort of consecutive 2722 donor oocyte IVF cycles. The relationship between donor BMI and clinical pregnancies was assessed after adjusting for recipient BMI. Clinical pregnancy rates and live birth rates (LBR) were no different with increasing donor BMI (up to donor BMI ≤28 kg/m2 ). The odds of pregnancy did not vary with donor BMI. Compared with donor BMI quartile 1, OR 95% CI of clinical pregnancy was 1...

Three new dimeric kavalactones, designated as diyangonins A-C (1-3), along with two known analogs were isolated from the roots of Piper methysticum. Their structures were elucidated by means of extensive analysis of their 1D, 2D NMR, and mass spectroscopic data. All these dimers possess a skeleton featuring a cyclobutane ring connecting two kavalactone units in head-to-tail or head-to-head mode. Compounds 1-5 were evaluated for their cytotoxic activities against human tumor cell lines.

Angiogenesis is implicated in the development of a variety of pathological processes, most commonly cancer. It is essential for tumor growth and metastasis, making it an important cancer therapeutic target. Naturally occurring substances have led to the discovery of anticancer agents. Flavokawain B (FKB), a chalcone isolated from the root extracts of kava-kava plant, inhibits proliferation and causes apoptosis in vitro and in vivo of various cancer cell lines. The antimetastatic potential of FKB has also been suggested...

Chalcones have been shown to exhibit anti-cancer properties by targeting multiple molecular pathways. It was, therefore, of interest to investigate flavokawain C (FKC), a naturally occurring chalcone, which can be isolated from Kava (Piper methysticum Forst) root extract. The aim of this study was to investigate the inhibitory effect of FKC on the growth of HT-29 cells and its underlying mechanism of action. Cell viability of HT-29 cells was assessed by Sulforhodamine B assay after FKC treatment. Induction of apoptosis was examined by established morphological and biochemical assays...

Nearly 25% of U.S. adults report concurrently taking a prescription medication with a dietary supplement. Some supplements, such as St. John's wort and goldenseal, are known to cause clinically important drug interactions and should be avoided by most patients receiving any pharmacologic therapy. However, many other supplements are predicted to cause interactions based only on in vitro studies that have not been confirmed or have been refuted in human clinical trials. Some supplements may cause interactions with a few medications but are likely to be safe with other medications (e...
