This paper describes mass production system of micro-tubes for microbial culture in an open environment. Microbes are used in many fields, such as food, medicine, environmental and energy. We proposed a microbe culture system using hydrogel micro-tubes, which can protect the target microbes inside from competitive microbes outside of the tubes while allow oxygen and nutrition to diffuse through. The hydrogel micro-tubes can be produced by a microfluidic device, which can precisely control the flow and therefore, the tube geometry...

The addition of gold nanoparticles within target tissue (i.e. a tumour) to enhance the delivered radiation dose is a well studied radiotherapy treatment strategy, despite not yet having been translated into standard clinical practice. While several studies have used Monte Carlo simulations to investigate radiation dose enhancement by Auger electrons emitted from irradiated gold nanoparticles, none have yet considered the effects due to escaping fluorescence photons. Geant4 was used to simulate a water phantom containing 10 mg/mL uniformly dispersed gold (1% by mass) at 5cm depth...

Veterinary drug residues in animal-derived foods must be monitored to ensure food safety, verify proper veterinary practices, enforce legal limits in domestic and imported foods, and for other purposes. A common goal in drug residue analysis in foods is to achieve acceptable monitoring results for as many analytes as possible, with higher priority given to the drugs of most concern, in an efficient and robust manner. The U.S. Department of Agriculture has implemented a multiclass, multi-residue method based on sample preparation using dispersive solid phase extraction (d-SPE) for cleanup and ultrahigh-performance liquid chromatography-tandem quadrupole mass spectrometry (UHPLC-QQQ) for analysis of >120 drugs at regulatory levels of concern in animal tissues...

A novel polymeric bioflocculant was produced by a bacterium utilizing degradation of n-hexadecane as the energy source. The bioflocculant was produced with a bioflocculating activity of 87.8%. The hydrocarbon degradation was confirmed by gas chromatography-mass spectrometry analysis and was further supported with contact angle measurements for the changes in hydrophobic nature of the culture medium. A specific aerobic degradation pathway followed by the bacterium during the bioflocculant production and hydrocarbon utilization process has been proposed...

BACKGROUND: Type 2 diabetes is associated with significant morbidity and mortality. Modifiable risk factors have been found to contribute up to 60% of type 2 diabetes risk. However, type 2 diabetes continues to rise despite implementation of interventions based on traditional risk factors. There is a clear need to identify additional risk factors for chronic disease prevention. The aim of this study was to examine the relationship between perceived stress and type 2 diabetes onset, and partition the estimates into direct and indirect effects...

The detection and quantification of spermine in clinical practice is important for early diagnosis of many diseases. The chromatographic and immunoassay-based methods are commonly used. However, fluorescence-based assay could provide real time detection. Herein, we report synthesis and aggregation properties of dicationic perylene probe (DAB-PDI) and used DAB-PDI in developing fluorescent 'turn-on' ensemble for detection of spermine. The fluorescence of DAB-PDI (10 µM, Φ = 0.55) is efficiently quenched by negatively charged sodium dodecylsulfate (SDS) through formation of ionic self-assembled aggregates (charge ratio N/P = 9)...

The period of British rule from 1757 to 1900 is marked by major sociopolitical changes and scientific breakthroughs that impacted medical systems, institutions, and practitioners in India. In addition, historians have debated whether the colonial regime used Western medicine as a tool to expand and legitimize its rule. This paper reviews the secondary literature on this subject with emphasis on the individual physicians. During this period, the practice of "Doctory" or Western medicine gained momentum in India, buoyed with the support of the British as well as Western-educated Indians...

Sarcopenia, defined as skeletal muscle loss and dysfunction, is attracting considerable attention as a novel risk factor for cardiovascular events. Although the loss of skeletal muscle is common in chronic kidney disease (CKD) patients, the relation between sarcopenia and cardiovascular events in CKD patients is not well defined. Therefore, we aimed to investigate the relation between skeletal muscle mass and major adverse cardiovascular events (MACE) in CKD patients. We enrolled 266 asymptomatic CKD patients (median estimated glomerular filtration rate: 36...

PURPOSE: Reduction mammoplasty (RM) during breast-conserving surgery is popular among women with large-volume breasts because it reduces redundant breast folds and may decrease skin-related morbidity from radiation therapy. However, RM may obscure the lumpectomy cavity (LC) and pose challenges to administering an LC boost, potentially affecting local control. We investigated the impact of RM on acute side effects and use of LC boosts. METHODS AND MATERIALS: The records of 645 consecutive women treated with whole-breast irradiation at an urban university and 2 community practices between January 2012 and December 2014 were reviewed on an institutional review board-approved study...

BACKGROUND: Irreversible electroporation (IRE) is an emerging technique delivering electrical pulses to ablate tissue, with the theoretical advantage to overcome the main shortcomings of conventional thermal ablation. Recent short-term research showed that IRE for the ablation of renal masses is a safe and feasible treatment option. In an ablate and resect design, histopathological analysis 4 weeks after radical nephrectomy demonstrated that IRE-targeted renal tumors were completely covered by ablation zone...

BACKGROUND: A certain minimal luminal cross-sectional area has been traditionally used in clinical practice as a cut-off value to determine severity of left main coronary artery (LMCA) stenosis. The severity of stenosis, however, depends on the baseline luminal area (ie, area prior to stenosis), which may vary among individuals. The present study was undertaken to define normal LMCA luminal area using current technology in vivo. METHODS: LMCA luminal area was determined using multislice computed tomography coronary angiography...
