Qualitative analysis of the structures of the polymers composing floating plastic debris was performed using attenuated total reflectance-Fourier transform infrared spectroscopy (ATR-FTIR), and the aging of the debris was assessed by measuring carbonyl group formation on the particle surfaces. Plastic material made up >75% of the 2313 items collected during a three-year survey. The size, shape and color of the microplastic were correlated with the polymer structure. The most abundant plastic materials were polypropylene (68%) and low-density polyethylene (11%), and the predominant colors of the plastics were white, blue and green...

Hepatitis B virus (HBV) is the smallest partially double-stranded DNA virus known to infect humans. Worldwide, more than 50% of hepatocellular carcinoma (HCC) cases are related to chronic Hepatitis B. Development of HCC from normal liver cells is characterized by changes in cell surface N-glycans, which can promote the invasive behavior of tumor cells, leading ultimately to the progression of cancer. However, little is understood about the cell surface N-glycans of HBV-infected liver cells. We try to address this by taking advantage of the HepAD38 cell line, which can replicate HBV in the absence of tetracycline [tet(-)] in growth medium...

Detection and use of physical noise fluctuations in a signal provides significant advantages in the development of bio- and neuro-sensing and functional mimicking devices. Low-dimensional carbon nanomaterials are a good candidate for use in noise generation due to the high surface sensitivity of these materials, which may themselves serve as the main building blocks of these devices. Here, we demonstrate that the addition of a molecule with high redox activity to a carbon nanotube (CNT) field-effect transistor provides tunable current fluctuation noise...

Fibrin is a plasma protein with a central role in blood clotting and wound repair. Upon vascular injury, fibrin forms resilient fibrillar networks (clots) via a multistep self-assembly process, from monomers, to double-stranded protofibrils, to a branched network of thick fibers. In vitro, fibrin self-assembly is sensitive to physicochemical conditions like the solution pH and ionic strength, which tune the strength of the noncovalent driving forces. Here we report a surprising finding that the buffer-which is necessary to control the pH and is typically considered to be inert-also significantly influences fibrin self-assembly...

In Indonesia, endoscopy services are limited and studies about gastric mucosal status by using pepsinogens (PGs) are rare. We measured PG levels, and calculated the best cutoff and predictive values for discriminating gastric mucosal status among ethnic groups in Indonesia. We collected gastric biopsy specimens and sera from 233 patients with dyspepsia living in three Indonesian islands. When ≥5.5 U/mL was used as the best cutoff value of Helicobacter pylori antibody titer, 8.6% (20 of 233) were positive for H...

BACKGROUND: Accuracy of consciousness level assessment is very important. It may determine and influence further clinical decisions, thus influences patients' outcomes. The widest method in determining the level of awareness is the Glasgow Coma Scale (GCS). Despite its common use, GCS scores obtained by one clinician may differ from others depending on their interpretations and past experience. One of the tools used to assess the level of consciousness objectively is bispectral index (BIS)...

Bacterial resistance to antibiotics is a serious problem worldwide that affect the increment of morbidity and mortality rate; Enterobacteriaceae producing ESBL is one of the causes. However, there are still limited information regarding diagnosis and management of ESBL-E infection. Detection of ESBL-E requires certain steps that are problematic and time consuming. Diagnosis and management of ESBL-E infection have become more and more challenging due to limited diagnostic method available and choice of antibiotics that may be used, along with growing subtyped of ESBL through various of mutations...
