The purpose of the present study was to develop and evaluate immunogens to elicit antibodies against the formation of amyloid beta protein (Aβ), a pathological hallmark of AD, as a therapeutic strategy in AD.

IL1RN Polymorphisms Are Associated with a Decreased Risk of Esophageal Cancer Susceptibility in a Chinese Population.

Background: Recent evidence suggested that IL1RN (interleukin-1 receptor antagonist) polymorphisms increased the susceptibility to cancers. The present study aimed to evaluate whether IL1RN was related to esophageal cancer susceptibility in a Northwest Han Chinese population.

Methods: The case-control study was conducted on 384 esophageal cancer patients and 499 healthy controls.

Impaired Cognitive Function and Altered Hippocampal Synaptic Plasticity in Mice Lacking Dermatan Sulfotransferase Chst14/D4st1.

Chondroitin sulfate (CS) and dermatan sulfate (DS) proteoglycans (PGs) are major extracellular matrix (ECM) components of the central nervous system (CNS). A large body of evidence has shown that CSPGs/DSPGs play critical roles in neuronal growth, axon guidance, and plasticity in the developing and mature CNS. It has been proposed that these PGs exert their function through specific interaction of CS/DS chains with its binding partners in a manner that depends on the sulfation patterns of CS/DS.

The aim of this study was to produce IgY specific to PDR-Ab and investigate its antibacterial effects in vitro and in vivo.

Antinociceptive Effect of Ghrelin in a Rat Model of Irritable Bowel Syndrome Involves TRPV1/Opioid Systems.

Background/aims: Irritable bowel syndrome (IBS), defined as recurrent abdominal pain and changes in bowel habits, seriously affects quality of life and ability to work. Ghrelin is a brain-gut hormone, which has been reported to show antinociceptive effects in peripheral pain. We investigated the effect of ghrelin on visceral hypersensitivity and pain in a rat model of IBS.

Growth-induced stress enhances epithelial-mesenchymal transition induced by IL-6 in clear cell renal cell carcinoma via the Akt/GSK-3β/β-catenin signaling pathway.

Stromal cell populations in the tumor microenvironment (TME) play a critical role in the oncogenesis and metastasis of renal cell carcinoma. In this study, we found that there are α-smooth muscle actin positive (α-SMA (+)) cells in the stroma of clear cell renal cell carcinoma (ccRCC) tissues, and their numbers are significantly associated with poor survival in ccRCC patients. Interleukin 6 (IL-6) is a critical diver that induces α-SMA (+) cells in ccRCC tissues via promotion of epithelial to mesenchymal transition (EMT) and stimulates migration and invasion in ccRCC.

Impact of tumor architecture on disease recurrence and cancer-specific mortality of upper tract urothelial carcinoma treated with radical nephroureterectomy.

Upper tract urinary carcinoma (UTUC) is a relatively uncommon but aggressive disease. Recent publications have assessed the prognostic significance of tumor architecture in UTUC, but there is still controversy regarding the significance and importance of tumor architecture on disease recurrence. We retrospectively reviewed the medical records of 101 patients with clinical UTUC who had undergone surgery.

Attitudes Toward Advance Directives Among Patients and Their Family Members in China.

Objectives: Chinese people are generally unfamiliar with the concept of advance care planning or advance directives (ACP/ADs), which raises dilemmas in life-support choice and can even affect clinical decision making. To understand and address the issues involved better, we investigated the awareness of ACP/ADs in China, as well as people's attitudes toward medical autonomy and end-of-life care.

Decreased glucagon-like peptide-1 correlates with abdominal pain in patients with constipation-predominant irritable bowel syndrome.

Background And Objective: The glucagon-like peptide-1 (GLP-1) analog, ROSE-010, plays a critical role in alleviating abdominal pain in patients with irritable bowel syndrome (IBS); however, the underling mechanism is unclear. In the present study, we determined the serum GLP-1 level in patients with constipation-predominant IBS (IBS-C). The relationship between GLP-1 and abdominal pain was investigated.

7-O-Geranylquercetin induces apoptosis in gastric cancer cells via ROS-MAPK mediated mitochondrial signaling pathway activation.

7-O-Geranylquercetin (GQ) is a novel O-alkylated derivate of quercetin. In this study, we evaluated its apoptosis induction effects in human gastric cancer cell lines SGC-7901 and MGC-803 and explored the potential molecular mechanisms. The results demonstrated that GQ lowered viability of SGC-7901 and MGC-803 cells in a dose- and time-dependent manner without apparent cytotoxicity to human gastric epithelial cell line GES-1.

Development of a Functional Glomerulus at the Organ Level on a Chip to Mimic Hypertensive Nephropathy.

Glomerular hypertension is an important factor exacerbating glomerular diseases to end-stage renal diseases because, ultimately, it results in glomerular sclerosis (especially in hypertensive and diabetic nephropathy). The precise mechanism of glomerular sclerosis caused by glomerular hypertension is unclear, due partly to the absence of suitable in vitro or in vivo models capable of mimicking and regulating the complex mechanical forces and/or organ-level disease processes. We developed a "glomerulus-on-a-chip" (GC) microfluidic device.

Jumonji AT-rich interactive domain 1B overexpression is associated with the development and progression of glioma.

Previous studies have suggested that jumonji AT-rich interactive domain 1B (JARID1B) plays an important role in the genesis of some types of cancer, and it is therefore considered to be an important drug target protein. Although the expression of JARID1B has been researched in some types of cancer, little is known about JARID1B expression in glioma and its function in the tumorigenesis of gliomas. In the present study, we examined the expression of JARID1B in glioma.
