Chuan-Ying Li, Cheng Wu
The purpose of this study was to determine the effect of omeprazole on the regulatory T cell (Treg) and T helper 17 (Th17)-mediated response in patients with duodenal ulcers (DUs). DU patients were randomly divided into omeprazole and colloid bismuth subcitrate treatment groups. The ratios of Th17 and Treg in peripheral blood mononuclear cells (PBMCs) were measured. Cytokine production and Foxp3(+)- and RORγt-positive cells were detected. The expressions of STAT3, p-STAT3, STAT5 and p-STAT5 were detected by Western blot...

Cytosolic and mitochondrial creatine kinases (CK), through the creatine kinase-phosphocreatine (CK/PCr) system, provide a temporal and spatial energy buffer to maintain cellular energy homeostasis. However, the effects of bacterial infections on the kidney remain poorly understood and are limited only to histopathological analyses. Thus, the aim of this study was to investigate the involvement of cytosolic and mitochondrial CK activities in renal energetic homeostasis in silver catfish experimentally infected with Aeromonas caviae...

Degeneration of the intervertebral discs is a progressive cascade of cellular, compositional and structural changes that is frequently associated with low back pain. As the first signs of disc degeneration typically arise in the disc's central nucleus pulposus (NP), augmentation of the NP via hydrogel injection represents a promising strategy to treat early to mid-stage degeneration. The purpose of this study was to establish the translational feasibility of a triple interpenetrating network hydrogel composed of dextran, chitosan, and teleostean (DCT) for augmentation of the degenerative NP in a preclinical goat model...

Pain is an unwelcome sleep partner. Pain tends to erode sleep quality and alter the sleep restorative process in vulnerable patients. It can contribute to next-day sleepiness and fatigue, affecting cognitive function. Chronic pain and the use of opioid medications can also complicate the management of sleep disorders such as insomnia (difficulty falling and/or staying asleep) and sleep-disordered breathing (sleep apnea). Sleep problems can be related to various types of pain, including sleep headache (hypnic headache, cluster headache, migraine) and morning headache (transient tension type secondary to sleep apnea or to sleep bruxism or tooth grinding) as well as periodic limb movements (leg and arm dysesthesia with pain)...

BACKGROUND & AIMS: Transforming growth factor beta (TGFB) suppresses early stages of tumorigenesis, but also contributes to migration and metastasis of cancer cells. A large number of human tumors contain mutations that inactivate its receptors, or downstream proteins such as Smad transcription factors, indicating that the TGFB signaling pathway prevents tumor growth. We investigated the effects of TGFB inhibition on liver tumorigenesis in mice. METHODS: C57BL/6 mice received hydrodynamic tail injections of transposons encoding HRAS(G12V) and a short hairpin RNA (shRNA) to downregulate p53, or those encoding HRAS(G12V) and MYC, or those encoding HRAS(G12V) and TAZ(S89), to induce liver tumor formation; mice were also given injections of transposons encoding SMAD7 or shRNA against SMAD2, SMAD3, SMAD4, or SNAI1 (Snail), with or without ectopic expression of Snail...

BACKGROUND: Maintenance of the native patellar thickness has been deemed important for proper clinical outcomes after total knee arthroplasty (TKA). Our objective was to study the effects of the change in patellar thickness on patient-perceived outcomes (PPOs) after TKA. We hypothesized that reestablishing native patellar thickness after TKA results in better PPOs. METHODS: 819 consecutive patients undergoing primary TKA were studied. Patients were classified according to their postoperative patellar thickness into: (1) less than native patella thickness; (2) equal to native patella thickness; and (3) greater than native patella thickness...

BACKGROUND: Primary osteoarthritis of the elbow is a less common indication for total elbow arthroplasty (TEA). Higher complication rates in younger, active patients may offset short-term improvements in pain and function. The purpose of this study was to determine pain relief, functional outcomes, complications, and survival of TEA in this population. METHODS: Between 1984 and 2011, 20 consecutive TEAs were performed for primary elbow osteoarthritis. Two patients died before the 2-year follow-up...

BACKGROUND: The management of large chin and lower lip defects is challenging due to this facial subunit's tremendous functional and aesthetic importance. Specific methods for total lower lip and mentum reconstruction are not well chronicled. Aesthetic and functional goals of this reconstruction include restoration of oral competence by maintaining lower lip height, vermilion reestablishment, color-matched skin introduction to the chin, sensation restoration, and ideally restoration of dynamic activity to the lower lip...

Climate variability and recurrent droughts have a strong negative impact on agricultural production and hydrology in the highlands northern Ethiopia. Since the 1980s, numerous mitigation and land rehabilitation measures have been implemented by local and national authorities to reduce these impacts, are often poorly effective. As underlying reason may be that controlling relationships between climate and ecohydrology at medium-sized catchments (10-10,000km(2)) of semi-arid highlands are not well known. We investigated trends and relationships in precipitation, temperature, streamflow, and net primary productivity (NPP)...

Water is a limiting factor and significant driving force for ecosystem processes in arid and semi-arid areas. Knowledge of plant water uptake pattern is indispensable for understanding soil-plant interactions and species coexistence. The 'Grain for Green' project that started in 1999 in the Loess Plateau of China has led to large scale vegetation change. However, little is known about the water uptake patterns of the main plant species that inhabit in this region. In this study, the seasonal variations in water uptake patterns of three representative plant species, Stipa bungeana, Artemisia gmelinii and Vitex negundo, that are widely distributed in the semi-arid area of the Loess Plateau, were identified by using dual stable isotopes of δ(2)H and δ(18)O in plant and soil water coupled with a Bayesian mixing model MixSIAR...

Chemokines are small soluble molecules that play critical roles in wound healing, infection, and cancer progression. In particular, overexpression of the C-C motif chemokine ligand 2 (CCL2) in multiple cancer types correlates with poor patient prognosis. Animal studies have shown that CCL2 signals to macrophages and breast cancer cells to promote tumor growth, invasion, and metastasis, indicating that CCL2 is a promising therapeutic target. However, the effectiveness of human-specific neutralizing antibodies has not been fully evaluated...

Adaptive management is an experimental approach used by water management agencies around the world to manage and restore aquatic ecosystems. The effectiveness of the approach can often be constrained by inflexible institutional arrangements. In this paper we compare two cases where agencies have implemented adaptive management to manage and restore aquatic ecosystems. Our aim was to understand practitioners' perceptions of how institutional flexibility can be created for adaptive management. We interviewed 14 adaptive management practitioners working in the Murray-Darling Basin, Australia and 14 practitioners in Southern Florida, United States of America...

Referrals and admissions to state psychiatric hospitals of criminal defendants found Incompetent to Stand Trial (IST) are on the rise in the state of California and other parts of the country. Studies of treatment outcomes of this population have primarily focused on factors that determine competency and/or restorability. However, as IST patients place an increasing resource burden on state psychiatric hospital systems, other outcomes such as length of stay (LOS) are becoming increasingly important for practitioners and policy makers to understand...

Myoepithelial cells are flat, stellate cells present in exocrine tissues including the salivary glands. While myoepithelial cells have been studied extensively in mammary and lacrimal gland tissues, less is known of the function of myoepithelial cells derived from human salivary glands. Several groups have isolated tumorigenic myoepithelial cells from cancer specimens, however, only one report has demonstrated isolation of normal human salivary myoepithelial cells needed for use in salivary gland tissue engineering applications...

INTRODUCTION: Inherited arrhythmias may arise from mutations in the SCN5a gene, which encodes the cardiac voltage-gated sodium channel, NaV 1.5. Mutants in NaV 1.5 result in Brugada Syndrome (BrS1), Long-QT Syndrome (LQT3), or mixed syndromes (an overlap of BrS1/LQT3). Exercise is a potential arrhythmogenic trigger in mixed syndromes. We sought to determine the effects of elevated cytosolic calcium, common during exercise, in mixed syndrome NaV 1.5 mutants. METHODS: We used whole-cell patch-clamp to assess the biophysical properties of NaV 1...
