BACKGROUND: Novel surveillance strategies are needed to detect the rapid and continuous emergence of infectious disease agents. Ideally, new sampling strategies should be simple to implement, technologically uncomplicated, and applicable to areas where emergence events are known to occur. To this end, xenosurveillance is a technique that makes use of blood collected by hematophagous arthropods to monitor and identify vertebrate pathogens. Mosquitoes are largely ubiquitous animals that often exist in sizable populations...

BACKGROUND: Diabetes self-care activities, like, healthy diet, regular exercise, self-monitoring of blood glucose, and rational use of medicines are considered to play a vital role in establishing euglycemia. Health literacy among type 2 diabetes mellitus (T2DM) patients in Pakistan is very low, which is the most likely cause for poor clinical outcomes. This study is designed to investigate the impact of pharmacist-led educational intervention on glycemic control, self-care activities and disease knowledge among T2DM patients in Pakistan...

High levels of shear stress can prevent and disrupt Pseudomonas aeruginosa biofilm formation in vitro. Intrapulmonary percussive ventilation (IPV) could be used to introduce shear stress into the lungs of cystic fibrosis (CF) patients to disrupt biofilms in vivo. We performed a first-of-its-kind pilot clinical study to evaluate short-term IPV therapy at medium (200 bursts per minute, bpm) and high frequency (400 bpm) as compared to autogenic drainage (AD) on lung function and the behavior of P. aeruginosa in the CF lung in four patients who are chronically colonized by P...

Practical tools which can be quickly administered are needed for measuring subtle changes in cognitive-motor performance over time. Frailty together with cognitive impairment, or 'cognitive frailty', are shown to be strong and independent predictors of cognitive decline over time. We have developed an interactive instrumented trail-making task (iTMT) platform, which allows quantification of motor planning error (MPE) through a series of ankle reaching tasks. In this study, we examined the accuracy of MPE in identifying cognitive frailty in older adults...

Background : Psychometric instruments such as the Repeated Battery for the Assessment of Neuropsychological Status (RBANS) are commonly used under conditions for which they were not developed or validated. They may then generate troublesome data that could conceal potential findings. Methods : Based on a previously published refinement of the RBANS, we reanalyzed the data on 303 patients from two National Institutes of Health (NIH) trails in Parkinson's disease and contrasted the results using the original versus refined scores...

INTRODUCTION: Clinical evidence gathered in recent years indicates that elderly individuals more frequently display cognitive changes. These age-related changes refer, above all, to memory functions and to the speed of thinking and reasoning. A number of studies have shown that physical activity can be used as an important mechanism for protecting the cognitive functions. AIM: To test the hypothesis that physical exercise is able to bring about changes in the cognitive functions of healthy elderly adults without cognitive impairment, thereby improving their quality of life...

Tumor necrosis factor-related apoptosis inducing ligand (TRAIL) is a member of tumor necrosis factor (TNF) superfamily and functions to promote apoptosis by binding to cell surface death receptor (DR)4 and DR5. Cancer cells are more sensitive than normal cells to TRAIL-induced apoptosis, and TRAIL-based therapeutic strategies have shown promise for the treatment of cancer. The present study investigated whether enforced overexpression of TRAIL in cervical cancer cells promoted cell death in the presence or absence of Taxol, an important first-line cancer chemotherapeutic drug...

Tumor necrosis factor (TNF)-related apoptosis-inducing ligand (TRAIL), which is TNF receptor superfamily member, contributes to several diseases pathogenesis. The aim of this research was to investigate the relevance of serum TRAIL protein levels and mRNA expression in peripheral blood mononuclear cells (PBMC) of patients with stroke through 6 months follow-up. We enrolled patients with first-ever acute ischemic stroke ( n  = 95) and healthy controls ( n  = 95) in this study. Follow-up blood samples were collected from patients at day 7, 28, and 180 after the onset...

BACKGROUND: Traumatic brain injury (TBI) is a major health problem that often requires intensive and long-term rehabilitation. OBJECTIVE: The aim of this study was to determine whether rehabilitative digital gaming facilitates cognitive functioning and general well-being in people with TBI. METHODS: A total of 90 Finnish-speaking adults with TBI (18-65 years) were recruited from an outpatient neuroscience clinic. The participants were randomly allocated to one of the three groups: a rehabilitation gaming group (n=29, intervention), an entertainment gaming group (n=29, active control), or a passive control group (n=32)...

PURPOSE: In spite of the unique advantages of minimally invasive treatment, laparoscopic surgery is not recommended in T4 colon cancer patients with the concern of technical feasibility and suboptimal oncologic outcomes. We used the database of our center to reevaluate laparoscopic surgery's value in T4 colon cancer and compared with open surgery in both short- and long-term outcomes. METHODS: We conducted a retrospective and propensity score-matched study of pathological T4 colon cancer patients who received laparoscopic surgery or open surgery from March 2011 to August 2015...

Tibial dyschondroplasia (TD) is a common skeletal problem of avian species. The cause and etiology of this disorder is still not clear. The intestinal bacterial community is a complex ecosystem and plays very important role in healthy life of human and animals. Many researchers have made the connection between diseases and alteration of gut microbiota. However, little is know about the role of gut microbiota in TD. The objective of this study was to explore the diversity and composition of small and large intestinal bacterial communities of TD chickens...

Escherichia coli is an essential host for large-scale expression of heterologous polypeptides. However, further applications are limited by the formation of potential protein aggregates. In this work, we developed a novel on-column tag removal and purification system based on Fh8 hydrophobic interaction chromatography purification and ΔI-CM self-cleavage to obtain soluble tumor necrosis factor-related apoptosis-inducing ligand (TRAIL). We evaluated several methods to improve TRAIL solubility and finally demonstrated that the Fh8 tag was a powerful solubility enhancer...

Objective: In visuo-constructional tasks, patients may reproduce drawings near-to or superimposed on a model, showing the so-called "Closing-in" (CI), often ascribed to a defect in inhibitory control. CI has been described in neurological conditions, but no studies have explored CI in Huntington's disease (HD), a neurodegenerative disorder often involving the frontal cortical-subcortical circuits. We searched for the occurrence of CI in HD patients and systematically investigated its correlates to find a clinical marker of the frontal/executive dysfunctions in the early examination of HD patients...

Monocyte chemotactic protein-induced protein-1 (MCPIP1; also called Regnase-1) encoded by the ZC3H12A gene critically regulates inflammatory responses and immune homeostasis primarily by RNase-dependent and -independent mechanisms. However, the relationship of MCPIP1 with apoptosis and cancer and the underlying mechanisms are largely unclear. The current study has demonstrated a previously uncovered connection between MCPIP1 and the negative regulation of death receptor 5 (DR5; also known as TRAIL-R2 or killer/DR5), a cell surface receptor for tumor necrosis factor-related apoptosis-inducing ligand (TRAIL), which is produced endogenously by various immune cells such as T cells...

INTRODUCTION: It has been estimated that a 10%-25% reduction in seven key risk factors could potentially prevent 1.1-3.0 million Alzheimer's disease cases globally. In addition, as dementia is preceded by more subtle cognitive deficits which have substantial social and economic impact, effective preventative interventions would likely have more extensive benefits. The current study evaluates in primary care a multidomain risk-reduction intervention targeting adults with high risk of developing dementia...

INTRODUCTION: Postoperative delirium (POD) is a common complication in elderly patients, characterised by a fluctuating course of altered consciousness, disordered thinking and inattention. Preliminary research has linked POD with persistent cognitive impairment and decreased quality of life. However, these findings maybe confounded by patient comorbidities, postoperative complications and frailty. Our objective is to determine whether POD is an independent risk factor for persistent impairments in attention and executive function after elective surgery...

Abdominal pregnancies represent 1.4% of extrauterine pregnancies. A literature search of six cases involving bowel ectopic pregnancies provided anecdotal treatment options. This case involves a woman admitted at 6 weeks gestation with right iliac fossa and shoulder tip pain. An ultrasound scan revealed an empty uterus with free fluid in both adnexa and a 31×21 mm heterogenous mass adjacent to the right ovary. At laparoscopy, an ectopic pregnancy was identified at the hepatic flexure. The patient received two doses of methotrexate and monitored until the beta human chorionic gonadotropin reduced...

Cold and hypoxia constitute the main environmental stressors encountered on the Antarctic Plateau. Hence, we examined whether central and/or peripheral acclimatisation to the combined stressors of cold and hypoxia would be developed in four men following an 11-day man-hauling expedition on this polar region. Before and after the journey, participants performed a static whole-body immersion in 21 °C water, during which they were breathing a hypoxic gas (partial pressure of inspired O2 : ~97 mmHg). To evaluate their local responses to cold, participants also immersed the hand into 8 °C water for 30 min, while they were whole-body immersed and mildly hypothermic [i...

AIM: This systematic review was conducted to explore the associations between sarcopenia, hospitalization and length of stay in the old people. METHODS: Pubmed, Embase, Medline and Cochrane Central Register of Controlled Trails from January 2009 to October 2017 were searched in this review. We included prospective studies, which had the clear definition of sarcopenia and reported the hospitalization or length of stay as one of outcomes. Adjusted Odd ratios (aORs), hazard ratios (aHRs) or relative risks (aRRs) extracted from the studies were combined to synthesize pooled effect measures...
