Bartonella species are arthropod-borne bacterial pathogens that infect numerous mammalian species. Small mammals play an important role as natural reservoirs of many Bartonella species, maintaining the greatest diversity of Bartonella described to date. Although Bartonella research has been conducted in Southeast Asia, no studies have been undertaken on small mammals in Singapore. Here, we report the detection and description of Bartonella in small mammals in Singapore during the period of November 2011 to May 2014...

Addressing drug resistance is a core challenge in cancer research, but the degree of heterogeneity in resistance mechanisms in cancer is unclear. In this study, we conducted next-generation sequencing (NGS) of circulating tumor cells (CTC) from patients with advanced cancer, to assess mechanisms of resistance to targeted therapy and reveal opportunities for precision medicine. Comparison of the genomic landscapes of CTC and tissue metastases is complicated by challenges in comprehensive CTC genomic profiling and paired tissue acquisition, particularly in patients who progress after targeted therapy...

Insulin-like Growth Factor 1 (IGF-1) and its signaling pathway play a primary role in normal growth and ageing, however serum IGF-1 is known to reduce with advancing age. Recent findings suggest IGF-1 is essential for neurogenesis in the adult brain, and this reduction of IGF-1 with ageing may contribute to age-related cognitive decline. Experimental studies have shown manipulation of the GH/GF-1 axis can slow rates of cognitive decline in animals, making IGF-1 a potential biomarker of cognition, and/or its signaling pathway a possible therapeutic target to prevent or slow age-related cognitive decline...

A new-type digital electric plum-blossom needle instrument of controllable and adjustable parameters was developed to achieve an automatic tapping instead of manual tapping technique and integrate the function of plum-blossom needle with that of micropulse electrical phase. The alternating current of periodic variation changes the direction of magnetic field around, induces the vibration of the cone head and tapping movement, outputs the micropulse current and acts on the affected area in treatment. The new-type digital electric plum-blossom needle instrument achieves the automatic tapping movement, precisely adjusts the stimulating strength and frequency according to diseases and integrates the tapping stimulation with pulse current to form circulation loop on the skin and intensify the therapeutic effects...

T S van den Bremer, Ø Breivik
During its periodic motion, a particle floating at the free surface of a water wave experiences a net drift velocity in the direction of wave propagation, known as the Stokes drift (Stokes 1847 Trans. Camb. Philos. Soc.8, 441-455). More generally, the Stokes drift velocity is the difference between the average Lagrangian flow velocity of a fluid parcel and the average Eulerian flow velocity of the fluid. This paper reviews progress in fundamental and applied research on the induced mean flow associated with surface gravity waves since the first description of the Stokes drift, now 170 years ago...

Fetal growth restriction and related placental pathologies such as preeclampsia, stillbirth, and placental abruption are believed to arise in early pregnancy when inadequate remodeling of the maternal spiral arteries leads to persistent high-resistance and low-flow uteroplacental circulation. The consequent placental ischaemia, reperfusion injury, and oxidative stress are associated with an imbalance in angiogenic/antiangiogenic factors. Many interventions have centered on the prevention and/or treatment of preeclampsia with results pertaining to fetal growth restriction and small-for-gestational-age pregnancy often included as secondary outcomes because of the common pathophysiology...

OBJECTIVE: Previous studies showed the aberrant expression of Src homology 2-containing inositol 5-phosphatase 2 (SHIP2) in GC tissue. However, the exact role of circulating SHIP2 in GC remains unclear. The aim of this manuscript was to analyze potential diagnostic and prognostic value of circulating SHIP2 levels in GC. PATIENTS AND METHODS: Circulating SHIP2 expression was detected in the plasma of 156 GC patients and 60 healthy controls by qRT-PCR. The receiver operating characteristic (ROC) curves were plotted to explore the reliability of circulating SHIP2 in detecting GC...

Despite the apparent superiority of arterial conduits for coronary artery bypass grafting (CABG), the long saphenous vein remains the most commonly used graft. The high failure rate of long saphenous vein grafts (SVGs) over time is therefore an important limiting factor for the long-term outcomes of CABG. Various methods to improve SVG patency have been proposed, although few have had a significant impact on clinical practice. External SVG supports have been a focus of research over the past 50 years, with their use intended to minimize well-documented pathophysiological changes that occur in the SVG following implantation into the coronary circulation...

BACKGROUND: Homoarginine (hArg) is known to have an impact on nitric oxide (NO) metabolism. It seems to increase NO generation and/or availability, thereby enhancing endothelial function. In addition, hArg is connected to energy metabolism since the key enzyme, L-arginine-glycine amidinotransferase (AGAT) for hArg synthesis in the kidneys, is also involved in the synthesis of energy metabolites like guanidinoacetate. Former studies indicate that low levels of hArg are linked to cardiovascular disease and increased all-cause mortality...

Circulating cell-free DNA in body fluids is an analyte of great interest in basic and clinical research. The analyses of DNA methylation and hydroxymethylation patterns in body fluids might allow one to determine the certain state of a disease, in particular of cancer. DNA methylation biomarkers in liquid biopsies, i.e. blood plasma samples, may help optimizing personalized therapy for individual patients. DNA methylation analyses of specific loci usually require a bisulfite conversion of the DNA, which requires a sufficiently high amount of DNA at the appropriate concentration...

DNA methylation is a chemically stable key-player in epigenetics. In the vertebrate genome the 5-methyl cytosine (5mC) has been found almost exclusively in the CpG dinucleotide context. CpG dinucleotides are enriched in CpG islands very frequently located within or close to gene promoters. Analyses of DNA methylation changes in human diagnostics have been conducted classically using methylation-sensitive restriction enzymes (MSRE). Since the discovery of bisulfite conversion-based sequencing and PCR assays, MSRE-based PCR assays have been less frequently used, although especially in the field of cancer epigenetics MSRE-based genome-wide discovery and targeted screening applications have been and are still performed successfully...

Androgens are steroid hormones with pleotropic and diverse biochemical and physiological functions, and androgen deficiency exerts a negative impact on human health. Testosterone (T) either directly or via its transformation into the more potent metabolite 5α-dihydrotestosterone (5α-DHT) or via aromatization into estradiol (E2) modulates important biochemical signaling pathways of human physiology and plays a critical role in the growth and/or maintenance of functions in a host of tissues and organs. T and 5α-DHT play an important role in regulating physiology of the muscle, adipose tissue, liver, bone, and central nervous system, as well as reproductive and sexual functions...

BACKGROUND: Parechoviruses (HPeV) are endemic seasonal pathogens detected from the respiratory tract, gut, blood and central nervous system (CNS) of children and adults, sometimes in conjunction with a range of acute illnesses. HPeV CNS infection may lead to neurodevelopmental sequelae, especially following infection by HPeV-3, hence screening and genotyping are important to inform epidemiology, aetiology and prognosis. OBJECTIVES: To identify and characterise HPeVs circulating during an outbreak between November 2013 and April 2014 in Queensland, Australia...

Traditionally, invasive coronary physiological assessment has focused on the epicardial coronary artery. More recently, appreciation of the importance of the coronary microvasculature in determining patient outcomes has grown. Several invasive modalities for interrogating microvascular function have been proposed. Angiographic techniques have been limited by their qualitative and subjective nature. Doppler wire-derived coronary flow reserve has been applied in research studies, but its clinical role has been limited by its lack of reproducibility, its lack of a clear normal value, and the fact that it is not specific for the microvasculature but interrogates the entire coronary circulation...

Vertical transmission of glucocorticoids via breast milk might pose a mechanism through which lactating women could prepare their infants for the postnatal environment. The primary source of breast-milk glucocorticoids is probably the systemic circulation. Research from our group showed that milk cortisol and cortisone concentrations follow the diurnal rhythm of maternal hypothalamus-pituitary-adrenal axis activity, with a higher abundance of cortisone compared to cortisol. Measurement of breast-milk glucocorticoid concentrations is challenging due to possible cross-reactivity with progestagens and sex steroids, which are severely elevated during pregnancy and after parturition...
