The physiological function of DPP-4 in proteolytic inactivation of incretins has been well established, however, there is limited information on the expression and the significance of DPP-4 in white adipose tissue with regard to obesity. The objective of the work was to reveal the expression and regulation of DPP-4 in adipocytes and compare the expression and activity of DPP-4 in white adipose tissue and several other organs such as the liver, muscle and kidney. We also investigated the gene expression levels of DPP-4 substrate chemokines, and their receptors in white adipose tissue...

Third-party altruistic decision-making has been shown to be modulated by other-regarding attention (e.g., focusing on the offender's crime or the victim's situation especially in judicial judgment). However, the neural mechanisms underlying this modulation remain poorly understood. In this fMRI study, participants voluntarily decided if they wanted to punish the first-party offender or help the second-party victim using their own monetary endowment in an unfair context. Particularly, before deciding they were asked to focus on the (un)fairness of the offender proposing the offer (offender-focused block, OB), the feeling of the victim receiving this offer (victim-focused block, VB), or without any specific focus (baseline block, BB)...

Obesity has become a severe public health problem across the world, and seriously affects the health and life quality of human beings. Here we generated lepr and mc4r mutant zebrafish via the CRISPR/Cas9 technique, and performed morphological and functional characterizations of those mutants. We observed that there was no significant phenotypic difference between homozygous mutants and wild-type controls before 2.5 months post-fertilization (mpf). However, the adult lepr(-/-) and mc4r(-/-) individuals displayed increased food intake, heavier weight, and higher body fat percentage, the characteristics of obesity phenotypes...

INTRODUCTION: Obstetrical care often involves multiple expensive, and often elective, interventions that may increase costs to patients, payers and the health care system with little effect on patient outcomes. The objectives of this study were to examine the following hospital related outcomes: 1) use of labor and birth interventions, 2) inpatient duration of stay, and 3) total direct health care costs for patients attended by a certified nurse-midwife (CNM) compared with those attended by an obstetrician-gynecologist (OB-GYN), within an environment of safe and high-quality care...

Die Necrobiosis lipoidica ist eine seltene granulomatöse Erkrankung von bisher unzureichend geklärter Ätiologie. Häufig stellt die bei Diabetikern gehäuft zu beobachtende und zur Ulzeration neigende Dermatose eine starke Belastung für die Patienten dar. Bezüglich der Therapie existieren aktuell keine deutschen oder europäischen Leitlinien. Gleichzeitig lässt sich unter der aktuellen Standardtherapie, der lokalen oder intraläsionalen Anwendung von Glukokortikoiden, nicht immer ein zufriedenstellendes Ansprechen beobachten...

BACKGROUND: The United Kingdom's National Institute for Health and Care Excellence (NICE) recently published recommendations that support planned home birth for low-risk women. The American College of Obstetricians and Gynecologists (ACOG) remains wary of planned home birth, asserting that hospitals and birthing centers are the safest birth settings. Our objective was to examine opinions of obstetricians in Salt Lake City, Utah about home birth in the context of rising home birth rates and conflicting guidelines...

Alzheimer's disease (AD) is characterized by progressive neuronal degeneration and pathological accumulation of amyloid plaques in the brain. It has been proposed that the prion-like spreading of amyloid beta (Aβ) protein could contribute to the progression of the disease. Olfactory bulb (OB) is one of the earliest brain regions affected in AD and olfaction is easily impaired prior to cognitive symptoms. However, it remains unclear whether Aβ accumulation in the OB would spread along olfactory projections to other connected brain regions and trigger further neurodegeneration...

Electrical cardiometry (EC) is a non-invasive and inexpensive method for hemodynamic assessment and monitoring. However, its feasibility for widespread clinical use, especially for the obese population, has yet to be determined. In this study, we evaluated the agreement and reliability of EC compared to transthoracic Doppler echocardiography (TTE) in normal, overweight, and obese children and adolescents. We measured stroke volume (SV) and cardiac output (CO) of 131 participants using EC and TTE simultaneously...

A 25-year-old man presented with chronic low back pain and occasional radiation to the right lower limb. Magnetic resonance imaging and computed tomography (CT) of the lumbar spine showed an osteolytic expansile lesion with a central sclerotic nidus in the right superior facet of the L5 vertebra and surrounding marrow oedema. The diagnosis of osteoblastoma was made based on imaging findings and confirmed after CT-guided biopsy. Radiofrequency ablation of the lesion was successfully performed. The patient tolerated the procedure well and showed symptomatic relief...

The cholinergic system has extensive projections to the olfactory bulb (OB) where it produces a state-dependent regulation of sensory gating. Previous work has shown a prominent role of muscarinic acetylcholine (ACh) receptors (mAChRs) in regulating the excitability of OB neurons, in particular the M1 receptor. Here, we examined the contribution of M1 and M3 mAChR subtypes to olfactory processing using mice with a genetic deletion of these receptors, the M1(-/-) and the M1/M3(-/-) knockout (KO) mice. Genetic ablation of the M1 and M3 mAChRs resulted in a significant deficit in odor discrimination of closely related molecules, including stereoisomers...

Although obesity and the metabolic syndrome (MS) often co-occur, many obese (OB) subjects have a favorable metabolic profile. It is unclear whether these factors independently influence cardiac electrophysiology including prolongation of the QT interval. We examined associations among obesity, MS, and prolonged corrected QT (QTc) interval in a large sample of Chinese research participants aged ≥35 years recruited from rural areas of Liaoning Province during 2012 to 2013. Of the 11,209 participants, 6,364 (56...

In celebration of the anniversary of the Journal of Applied Psychology (JAP), we take a hundred-year journey to examine how the science of cross-cultural industrial/organizational psychology and organizational behavior (CCIO/OB) has evolved, both in JAP and in the larger field. We review broad trends and provide illustrative examples in the theoretical, methodological, and analytic advances in CCIO/OB during 4 main periods: the early years (1917-1949), the middle 20th century (1950-1979), the later 20th century (1980-2000), and the 21st century (2000 to the present)...

OBJECTIVES: Stiffness of bone tissue differs response to its physiological or pathological status, such as osteoporosis or osteosclerosis. Consequently, the function of cells residing in bone tissue including osteoblasts (OBs), osteoclasts and osteocytes will be affected. However, to the best of our knowledge, the detailed mechanism of how extracellular matrix stiffness affects OB function remains unclear. MATERIALS AND METHODS: We conducted a study that exposed rat primary OBs to polydimethylsiloxane substrates with varied stiffness to investigate the alterations of cell morphology, osteoblastic differentiation and its potential mechanism in mechanotransduction...

Despite multimodal therapeutic treatments of osteosarcoma (OS), some patients develop resistance to currently available regimens and eventually end up with recurrent or metastatic outcomes. Many attempts have been made to discover effective drugs for improving outcome; however, due to the heterogeneity of the disease, new therapeutic options have not yet been identified. This study aims to explore potential targeted therapy related to protein profiles of OS. In this review of proteomics studies, we extracted data on differentially expressed proteins (DEPs) from archived literature in PubMed and our in-house repository...

Prostaglandin E2 (PGE2) is derived from arachidonic acid, while PGE3 is derived from eicosapentaenoic acid (EPA) using the same downstream metabolic enzymes. Little is known about the impact of EPA and PGE3 on β-cell function, particularly in the diabetic state. In this work, we determined PGE3 elicits a 10-fold weaker reduction in glucose-stimulated insulin secretion through the EP3 receptor as compared to PGE2 We tested the hypothesis that enriching pancreatic islet cell membranes with EPA, thereby reducing arachidonic acid abundance, would positively impact β-cell function in the diabetic state...

Bone homeostasis depends on the functional balance of osteoblasts (OBs) and osteoclasts (OCs). Lrp4 is a transmembrane protein that is mutated in patients with high bone mass. Loss of Lrp4 in OB-lineage cells increases bone mass by elevating bone formation by OBs and reducing bone resorption by OCs. However, it is unclear how Lrp4 deficiency in OBs impairs osteoclastogenesis. Here, we provide evidence that loss of Lrp4 in the OB lineage stabilizes the prorenin receptor (PRR) and increases PRR/V-ATPase-driven ATP release, thereby enhancing the production of the ATP derivative adenosine...

BACKGROUND: The mammalian primary olfactory system has a spatially-ordered projection in which olfactory sensory neurons (OSNs) located in the dorsomedial (DM) and ventrolateral (VL) region of the olfactory epithelium (OE) send their axons to the dorsal and ventral region of the olfactory bulb (OB), respectively. We previously found that OSN axonal projections occur sequentially, from the DM to the VL region of the OE. The differential timing of axonal projections is important for olfactory map formation because early-arriving OSN axons secrete guidance cues at the OB to help navigate late-arriving OSN axons...
