#1
Jun-Ichiro Nakamura, Kiyoshi Yoshihara
BACKGROUND: Percutaneous full-endoscopic discectomy (PED) is being increasingly used because of its potential to minimalize soft-tissue damage and decrease hospital stay. PED using the interlaminar approach (PED-IL) at L4-L5 is performed by only a few surgeons. To the best of our knowledge, the safety and efficacy of PED-IL at L4-L5, without experience in PED via a transforaminal approach (PED-TF) has not been previously reported. OBJECTIVE: This study aimed to evaluate initial clinical outcomes and complications of PED-IL at L4-L5 without experience in PED-TF...

Two up-flow blanket filter (UBF) reactors were employed to treat synthetic wastewater with different substrate concentrations and nitrogen load rates (NLR) for 178days. During days 0-60, higher influent NLR of R2 (0.21-0.58kg·m(3)·d) slowed down the formation of anammox sludge compared with the lower NLR of R1 (0.18-0.31kg·m(3)·d). Difference in sludge color and nitrogen conversion rate indicated greater anammox activity of R2 than R1. During days 61-178, R1 and R2 achieved the maximum nitrogen removal rates (NRR) of 1...

Background and Objectives: There is a substantial body of literature on the importance of the environment in the lives of older adults. Nonetheless, to date, there has been limited research on everyday activities of urban older adults in public open spaces. The present study examined the activities of older adults in public open spaces in Israel with a specific focus on age and gender as potential variables of relevance. Research Design and Methods: Using still photography, we systematically photographed four sessions in two different public outdoor settings attended by older Israelis...

AIM: Acute kidney injury (AKI) is common following deliberate self-poisoning with a combination washing powder containing oxalic acid (H2C2O4) and potassium permanganate (KMnO4). Early and rapid increases in serum creatinine (sCr) follow severe poisoning. We investigated the relationship of these increases with direct nephrotoxicity in an ongoing multicenter prospective cohort study in Sri Lanka exploring AKI following poisoning. METHODS: Multiple measures of change in kidney function were evaluated in 48 consenting patients who had serial sCr and serum cystatin C (sCysC) data available...

The use of dimensionally ordered ligands on layered materials to direct local electronic structure and interactions with the environment promises to streamline integration into nanostructured electronic, optoelectronic, sensing, and nanofluidic interfaces. Substantial progress has been made in using ligands to control substrate electronic structure. Conversely, using the exposed face of the ligand layer to structure wetting and binding interactions, particularly with scalable solution- or spray-processed materials, remains a significant challenge...

A pair of linear tetrafluorinated small molecular donors, named as ThIDTTh4F and ThIDTSe4F, which are with tetrathienyl-substituted IDT as electron-rich central core, electron-deficient difluorobenzothiadiazole as acceptor units, and donor end-capping groups, but having differences in the π-bridge (thiophene and selenophene), were successfully synthesized and evaluated as donor materials in organic solar cells. Such π-bridge and core units in these small molecules play a decisive role in the formation of the nanoscale separation of the blend films, which were systematically investigated through absorption spectra, grazing incidence X-ray diffraction pattern, transmission electron microscopy images, resonant soft X-ray scattering profiles, and charge mobility measurement...

Gastric cancer (GC) is one of the most common malignancies worldwide. The prognosis of GC is poor, mostly due to widespread metastasis. p21-activated kinase 1 (Pak1), the best characterized member of an evolutionarily conserved family of serine/threonine kinases, plays an important role in the regulation of cell morphogenesis, motility, mitosis and angiogenesis. By qRT-PCR and Gelatin zymograph assay, we demonstrated in the present study that stable overexpression of Pak1 induced matrix metalloproteinase (MMP)-2 mRNA expression and activity in the human MKN45 GC cell line...

A large number of previous clinical studies have reported a delayed graft function for brain dead donors, when compared with living relatives or cadaveric organ transplantations. However, there is no accurate method for the quality evaluation of kidneys from brain‑dead donors. In the present study, two‑dimensional gel electrophoresis and MALDI‑TOF MS‑based comparative proteomic analysis were conducted to profile the differentially‑expressed proteins between brain death and the control group renal tissues...

Mild Cognitive Impairment is a preclinical stage of Alzheimer's disease (AD). For effective treatment of AD, it is important to identify MCI patients who are at a high risk of developing AD over the course of time. İn this study, autoregressive modelling of multiple heterogeneous predictors of Alzheimer's dısease is performed to capture their evolution over time. The models are trained using three different arrangements of longitudinal data. These models are then used to estimate future biomarker readings of individual test subjects...

Oxygen evolution reaction (OER) has played a pivotal role in many energy conversion and storage technologies like water electrolysis, fuel cells, and metal-air batteries. However, the slow kinetics of OER limit the performance and commercialization of such devices. Herein, we report on NiFe LDH@Au hybrid nanoarrays on Ni foam for much enhanced OER. By hybridization of electronegative Au and NiFe LDH with intrinsic remarkable OER catalytic activity, this modular electrode could drive an overall ultrahigh-performance and robust OER in base with the demand of overpotentials of only 221, 235 and 270 mV to afford 50, 100 and 500 mA cm-2, respectively...

Thermo-electrochemical cells (also called thermocells) are promising devices for harvesting waste heat for the sustainable production of energy. Research into thermocells has increased significantly in recent years, driven by advantages such as their ability to continuously convert heat into electrical energy without producing emissions or consuming materials. Until relatively recently, the commercial viability of thermocells was limited by their low power output and conversion efficiency. However, there have lately been significant advances in thermocell performance as a result of improvements to the electrode materials, electrolyte and redox chemistry and various features of the cell design...

A novel one-pot approach selects a hydrothermally synthesized Cu/SiO2 catalyst (consisting of Cu2O·SiO2 and Cu(0) surface species) to catalyze the reduction of a series of fatty esters, fatty acids, and coconut oil to fatty alcohols at 240 °C in methanol without extraneous hydrogen, attaining around 85% conversion and 100% selectivity.

Tumor recurrence in glioblastoma (GBM) is, in part, attributed to increased epithelial-to-mesenchymal transition (EMT) and enhanced tumor cell dissemination in adjacent brain parenchyma after ionizing radiation (IR). EMT is associated with aggressive behavior, increased stem-like characteristics and treatment resistance in malignancies; however, the underlying signaling mechanisms that regulate EMT are poorly understood. We identified grade-dependent p21-activated kinases 4 (PAK4) upregulation in gliomas and further determined its role in mesenchymal transition and radioresistance...

INTRODUCTION: Open reduction and internal fixation (ORIF) is standard care for most acetabular fractures. With increasing numbers of acetabular fractures in the elderly, the risk of revision surgery and conversion to total hip replacement (THR) is increasing. Alarmingly, about 20-25% of acetabular fractures in the elderly following ORIF needed revision and conversion to delayed THR. METHODS: Recently, prognostic factors have been identified, which correlate with an increased risk of worse outcomes following ORIF of acetabular fractures in the elderly patient...

PURPOSE: Despite the increasing prevalence of obesity and gastric diseases, the impact of obesity on short- and long-term outcomes of laparoscopic distal gastrectomy for gastric cancer still remains unclear. METHODS: Sixty-one consecutive obese patients with body mass index (BMI)≥30 kg/m(2), who underwent laparoscopic distal gastrectomy, were compared with 76 non-obese patients with BMI<30 kg/m(2). Short- and long-term outcomes were analyzed in both groups...
