The synthesis of "rim-differentiated" C5-symmetric pillar[5]arenes, whose two rims are decorated with different chemical functionalities, has remained a challenging task. This is due to the inherent statistical nature of the cyclization of 1,4-disubstituted alkoxybenzenes with different substituents, which leads to four constitutional isomers with only 1/16th being rim-differentiated. Herein, we report a "pre-oriented" synthetic protocol based on FeCl3-catalyzed cyclization of asymmetrically-substituted 2,5-dialkoxybenzyl alcohols...

The performance of organic photovoltaics (OPVs) based on the small-molecule organic semiconductor p-DTS(FBTTh2 )2 is greatly improved by the addition of a conjugated block copolymer composed of difluoroquinoxaline and thienopyrrolodione blocks (D130). The power conversion efficiency (PCE) of the p-DTS(FBTTh2 )2 -based OPV is improved from 5.08% to 6.75% by the addition of 5 wt% D130 to the photoactive layer, which is composed of p-DTS(FBTTh2 )2 and a fullerene derivative. Current-voltage and grazing incidence wide-angle X-ray scattering analyses revealed that the addition of D130 significantly reduces the trap density of the device and changes the packing orientation of p-DTS(FBTTh2 )2 from mostly edge-on to partially face-on...

Glioblastoma multiforme (GBM) is one of the most malignant and aggressive brain tumors with great amount of hyaluronan (HA) secretion and CD44 overexpression (HA receptor). CD44 has been suggested as a cancer stem cells (CSCs) marker. However, several clinical studies have indicated that CD44low glioma cell exhibit CSCs traits. Additionally, our previous study indicated that more CD44 expression was associated with a better prognosis in GBM patients. To determine whether CD44 is an appropriate marker of glioma stem cells (GSCs), we manipulated CD44 expression using intrinsic (CD44 knockdown, CD44kd) and extrinsic (HA supplement, HA+) methods...

We found that molecular baskets 1-3, with amino acids at their rim, undergo photoinduced decarboxylations to give baskets 4-6 forming a solid precipitate in water. Furthermore, organophosphonates 7-9 (OP), akin in size and shape to G-type nerve agents, form inclusion complexes with baskets 1-3 (K = 6-2243 M-1). Light irradiation (300 nm) of an aqueous solution of 1-3⊂OP led to the formation of precipitate containing an OP compound thereby amounting to a novel strategy for light-induced sequestration of nerve agents or, perhaps, other targeted compounds...

Autographa californica nucleopolyhedrovirus (AcMNPV) orf75 (ac75) is a highly conserved gene of unknown function. In this study, we constructed an ac75 knockout AcMNPV bacmid and investigated the role of ac75 in the baculovirus life cycle. The expression and distribution of the Ac75 protein were characterized, and its interaction with another viral protein was analyzed to further understand its function. Our data indicated that ac75 was required for the nuclear egress of nucleocapsids, intranuclear microvesicle formation, and subsequent budded virion (BV) formation, as well as occlusion-derived virion (ODV) envelopment and embedding of ODVs into polyhedra...

Histone demethylases are known to play important roles in the determination of the fate of stem cells and in cancer progression. In this study, we show that the lysine 4 of histone H3 (H3K4), lysine-specific demethylase 5A (KDM5A) is essential for the repression of astrocyte differentiation in neural progenitor cells (NPCs), and its expression is regulated by translational machinery. Knockdown of KDM5A in NPCs increased astrocytogenesis, and conversely, KDM5A overexpression reduced the transcriptional activity of the Gfap promoter...

Incision and drainage is the management plan of any infected sebaceous cyst from old age. But in infected sebaceous cyst, we can treat it in a simple way.Under local or general anesthesia the infected tissue is excised along with a rim of healthy tissue and then closed by Prolene in the same sitting. Usually stitches are removed on 21st day in the back and 14th day in the limb. This cross sectional observational study was carried out in the Department of Surgery of 250 Bed District Hospital, Kishoreganj and local clinics of Kishoreganj, Bangladesh from January 2012 to March 2015...

Trigeminocardiac reflex is a sudden physiologic response due to mechanical manipulation of any of the branches of trigeminal nerve. Trigeminocardiac reflex occurs due to pressure effect or stretching of trigeminal nerve which causes fall in blood pressure and decrease in heart rate. In this reflex arc, the trigeminal nerve serves as afferent pathway and vagus nerve, which is cardio inhibitory in nature, serves as efferent pathway. Two episodes of trigeminocardiac reflex during maxillofacial trauma surgery is not a common phenomenon...

Liver inflammation is closely associated with metabolic syndrome. Oxidative stress plays a synergistic role in inflammation by activating nuclear factor kappa B (NF-κB) signaling in the liver. Therefore, substantial efforts have been made to develop compounds that inhibit the generation of oxidative stress and activation of NF-κB. We synthesized twenty-six novel 5-(substituted benzyl)-2-oxo- and 5-(substituted benzyl)-2-thioxo-dihydropyrimidine-4,6(1H,5H)-dione derivatives for the development of potential antioxidants and examined their biological activities in vitro and in vivo...

BACKGROUND: In the first CONCORD study (2008), 5-year survival for patients diagnosed with colon cancer between 1990 and 1994 in the United States was among the highest in the world (60%), but there were large racial disparities in most participating states. The CONCORD-2 study (2015) enabled the examination of survival trends between 1995 and 2009 for US states by race and stage. METHODS: The authors analyzed data from 37 state population-based cancer registries, covering approximately 80% of the US population, for patients who were diagnosed with colon cancer between 2001 and 2009 and were followed through 2009...

The increasing demand for total hip arthroplasty (THA) in relatively young, high-demand patients has led to the use of hard-on-hard bearing surfaces. Adverse local tissue reaction/pseudotumor and elevated serum metal ion levels are commonly reported complications encountered in metal-on-metal THA, while audible articulation and rim fracture are reported in ceramic-on-ceramic THA. For this reason, ceramic-on-metal THA was implemented as an ideal hard-on-hard bearing combination. In this report, we describe a case of bilateral simultaneous ceramic-on-metal THA in a 69-year-old woman who presented 7 years postoperatively with unilateral hip pain associated with underlying pseudotumor and elevated serum cobalt and chromium ion levels...

A bone-remodeling imbalance induced by increased bone resorption and osteoclast formation causes skeletal diseases such as osteoporosis. Induction of osteogenic differentiation of bone marrow stromal cells (BMSCs) leads to bone regeneration. Many researchers have tried to develop new adjuvants as specific stimulators of bone regeneration for therapeutic use in patients with bone resorption. We tried to develop a new adjuvant that has stronger osteogenic differentiation-promoting activity than bone morphogenetic proteins (BMPs)...
