Vibrio vulnificus is a causative agent of fatal septicemia and necrotic wound infection and the pathogen infection became an important public health problem in many counties. Vibrio vulnificus causes RtxA1 toxin-induced acute cell death. We tried to identify natural products that inhibit the acute cytotoxicity of V. vulnificus using a lactate hydrogenase assay. A polyphenol pyrogallol protected HeLa cells from V. vulnificus-induced cytotoxicity. Pyrogallol also decreased the growth of V. vulnificus; this inhibitory effect was more significant during log phase than stationary phase...

BACKGROUND: Stroke patients develop compensatory movements due to limitations of ankle dorsiflexion and knee flexion. To solve the limitations, there are many adjustable walking assistive devices such as robotic devices, ankle-foot orthoses, and functional electric stimulation in rehabilitation session. However, these assistive devices have some disadvantages, including expense and discomforts. Therefore, the development of a new assistive device for stroke patients is needed to assist ankle dorsiflexion and knee flexion...

BACKGROUND: We examined the association between HbA1c variability and renal disease progression based on estimated glomerular filtration rate (eGFR) decline in patients with type 2 diabetes mellitus (T2DM) in Singapore. METHODS: We retrospectively assessed the glycemic burden and renal function in 1628 patients in 2002-2014. Multivariable logistic regression was used to assess the relationships between HbA1c variability expressed as HbA1c coefficient of variation (HbA1c-CV) in quartiles, HbA1c-intrapersonal mean and eGFR decline, adjusted for baseline covariates...

Salmonella infection is the one of the major causes of food borne illnesses including fever, abdominal pain, diarrhea, and nausea. Thus, early detection of Salmonella contamination is important for our healthy life. Conventional detection methods for the food contamination have limitations in sensitivity and rapidity; thus, the early detection has been difficult. Herein, we developed a bioelectronic nose using a carbon nanotube (CNT) field-effect transistor (FET) functionalized with Drosophila odorant binding protein (OBP)-derived peptide for easy and rapid detection of Salmonella contamination in ham...

We introduce femtosecond wide-field transient absorption microscopy combining sub-10 fs pump and probe pulses covering the complete visible (500-650 nm) and near-infrared (650-950 nm) spectrum with diffraction-limited optical resolution. We demonstrate the capabilities of our system by reporting the spatially- and spectrally-resolved transient electronic response of MAPbI3-xClx perovskite films and reveal significant quenching of the transient bleach signal at grain boundaries. The unprecedented temporal resolution enables us to directly observe the formation of band-gap renormalization, completed in 25 fs after photoexcitation...

AIMS: Patients with diabetic kidney disease (DKD) on anti-diabetic agents, are at greater risk of glycemic variations, both hypoglycemia and hyperglycemia. We aimed to compare glycemic control (using HbA1c) and hypoglycemia incidence in patients with Stage 3 DKD (eGFR 30-60 ml/min/1.73 m(2) ), receiving retrospective CGM-guided anti-diabetic therapy versus self-monitoring of blood glucose (SMBG) over 3 months. METHODS: Thirty patients with HbA1c > 8% were randomized to 6-day retrospective CGM or SMBG...

Metastasis is one of the most characteristic yet problematic behaviors of cancer cells. Stage IV breast cancer accounts for a large portion of breast cancer-related morbidity and mortality. Despite early detection and improvement in survival owing to advancements in biomedical research and overall improvement of the health system, 6-10% of patients present with stage IV disease in the developed world, with a higher incidence noted elsewhere. Despite advances in biomedical research into cancer, up to 70-80% of patients with stage IV breast cancer die of cancer in 5 years, a disproportionally higher mortality compared with non-metastatic breast cancer...

Phase-amplitude coupling (PAC) plays an important role in neural communication and computation. Interestingly, recent studies have indicated the presence of ubiquitous PAC phenomenon even during the resting state. Despite the importance of PAC phenomenon, estimation of significant physiological PAC is challenging because of the lack of appropriate surrogate measures to control false positives caused by non-physiological PAC. Therefore, in the present study, we evaluated PAC phenomenon during resting-state magnetoencephalography (MEG) signal and considered various surrogate measures and computational approaches widely used in the literature in addition to proposing new ones...

Mechanical strain due to increased pressure or swelling activates inflammatory responses in many neural systems. As cytokines and chemokine messengers lead to both pro-inflammatory and neuroprotective actions, understanding the signaling patterns triggered by mechanical stress may help improve overall outcomes. While cytokine signaling in neural systems is often associated with glial cells like astrocytes and microglia, the contribution of neurons themselves to the cytokine response is underappreciated and has bearing on any balanced response...

Pancreatic ductal adenocarcinoma (PDAC) is considered a non-immunogenic tumor, and immune checkpoint inhibitor monotherapy lacks efficacy in this disease. Radiotherapy (RT) can stimulate the immune system. Here, we show that treatment of KPC and Pan02 murine PDAC cells with RT and gemcitabine upregulated PD-L1 expression in a JAK/Stat1-dependent manner. In vitro, PD-L1 inhibition did not alter radio- and chemosensitivity. In vivo, addition of anti-PD-L1 to high (12, 5 × 3, 20 Gy) but not low (6, 5 × 2 Gy) RT doses significantly improved tumor response in KPC and Pan02 allografts...

OBJECTIVE: The extent to which increasing age is associated with impairment in cognitive function, termed cognitive aging, may have been overestimated in prior studies. The inclusion of individuals with severe or uncontrolled systemic medical illness or prodromal neurodegenerative disease in normal aging samples is likely to bias estimates toward lower cognitive performance and inflate estimates of variability. METHOD: Unbiased estimates of cognitive aging in 658 adults aged 60-84, who underwent rigorous screening to ensure their general and cognitive health, were computed...

Activities of TIS21(/BTG2) gene regulating cancer cell senescence were investigated in hepatoma cells by using low dose doxorubicin (Doxo, 100ng/mL). Treatment of Huh7 cells with Doxo increased linear actin nucleation e.g., transverse arcs and ventral stress fibers, as opposed to loss of filopodia. The linear actin nucleation was accompanied with thick vimentin networks at periphery of the cells, when examined by super-resolution STED microscope. However, expression of TIS21 inhibited ABI2-DRF pathway by inhibiting DRF expression and reducing ABI2 protein stability...

Anesthesia for patients with moderate aortic stenosis accompanied by atrial fibrillation during high-risk surgery such as liver transplantation remains a challenge in maintaining control of heart rate and maintenance of cardiac output. The action of terlipressin on vasopressin receptors (mainly V1 receptors) leads to splanchnic vasoconstriction and is the key mechanism responsible for increasing systemic vascular resistance and reducing heart rate. We report successful anesthetic management using low-dose terlipressin infusion in an elderly patient who had moderate aortic stenosis with atrial fibrillation during urgent deceased-donor liver transplantation...

BACKGROUND: Spindle cell lipoma is an uncommon variant of lipoma and usually occurs as a solitary, subcutaneous, and well circumscribed lesion in the posterior neck, shoulders, and back of older men. Primary renal lipomas are rarely reported. Spindle cell lipoma in the kidney has not been previously described in the literature. CASE REPORT: A 60-year-old Chinese man suffered graft failure 10 years after living related donor kidney transplantation. During cancer surveillance, he was found to have a mass in the renal allograft, which increased in size and was suspicious for renal cell carcinoma on computerized tomographic scan...
