Opisthorchis viverrini infection induces chronic inflammation, and a minor proportion of infected individuals develop advanced periductal fibrosis (APF) and cholangiocarcinoma (CCA). Inflammatory cytokines and/or their gene polymorphisms may link to these biliary pathologies. We therefore investigated associations among cytokine gene polymorphisms and cytokine production in 510 Thai cases infected with O. viverrini who presented with APF+ or APF-, as established by abdominal ultrasonography as well as in patients diagnosed with CCA...

INTRODUCTION: It is hypothesized that cerebral hypoperfusion promotes the development of Alzheimer pathology. We therefore studied whether longstanding cerebral hypoperfusion is associated with Alzheimer pathology in nondemented humans. METHODS: Cerebral blood flow and β-amyloid ((18)F-Flutemetamol) positron emission tomography retention were assessed in eleven patients with unilateral occlusion of precerebral arteries resulting in chronic and uneven hypoperfusion...

INTRODUCTION/PURPOSE: Many male marathon runners have elevated coronary artery calcium (CAC) scores despite high physical activity. We examined the association between CAC scores, cardiovascular risk factors, and lifestyle habits in long term marathoners. METHODS: We recruited men who had run ≥1 marathon annually for 25 consecutive years. CAC was assessed using coronary computed tomography angiography. Atherosclerotic cardiovascular disease (CAD) risk factors were measured with a 12-lead ECG, serum lipid panel, height, weight, resting blood pressure and heart rate, and a risk factor questionnaire...

Thrombi that occlude blood vessels can be resolved with fibrinolytic agents that degrade fibrin, the polymer that forms between and around platelets to provide mechanical stability. Fibrinolysis rates however are often constrained by transport-limited delivery to and penetration of fibrinolytics into the thrombus. Here, these limitations are overcome with colloidal microwheel (µwheel) assemblies functionalized with the fibrinolytic tissue-type plasminogen activator (tPA) that assemble, rotate, translate, and eventually disassemble via applied magnetic fields...

Aedes aegypti is the primary vector of a number of human pathogens including dengue virus (DENV) and Zika virus (ZIKV). Ae. aegypti acquires these viruses during the processing of bloodmeals obtained from an infected vertebrate host. Vertebrate blood contains a number of factors that have the potential to modify virus acquisition in the mosquito. Interestingly, low density lipopolyprotein (LDL) levels are decreased during severe DENV infection. Accordingly, we hypothesized that LDL is a modifiable factor that can influence flavivirus acquisition in the mosquito...

Rehmannia glutinosa polysaccharide (RGP) has exhibited an immune stimulatory effect, such as dendritic cell activation, but it has not been studied in terms of the activation capacity of natural killer (NK) cells in mice in vivo. In this study, we examined the effect of RGP on the proliferation and activation of NK cells in the spleen, mesenteric lymph node (mLN), and blood in vivo and compared that function with that of Escherichia coli lipopolysaccharide. The administration of RGP to C57BL/6 mice induced the increase in circulating blood NK cell numbers and in the proliferation of NK cells in the spleen, mLN, and blood...

A common pathological feature of neurodegenerative disorders (NDs), such as Alzheimer's (AD) and Parkinson's (PD) diseases, is the abnormal accumulation and misfolding of specific proteins, primarily α-synuclein (α-syn), β-amyloid1-42 (Aβ) and tau, in brain and in peripheral tissues too. Oxidative stress has been proved to be involved in NDs at various levels and, in particular, in such protein alterations, on the contrary physical activity is emerging as a counteracting factor in NDs. In the present work, the content of Aβ, α-syn and tau in red blood cells (RBCs) derived from ten endurance athletes (ATHL) and ten sedentary volunteers (SED) were compared before and after in vitrooxidative stress treatment...

Purpose: Proinflammatory cytokines such as tumor necrosis factor (TNFα) may have a causative role in blood-retinal barrier (BRB) disruption, which is an essential step in the development of diabetic macular edema. The purpose of our study was to determine whether TNFα increases permeability in an in vitro model of the BRB and to explore the mechanisms involved. Methods: Primary bovine retinal endothelial cells (BRECs) were grown on Transwell inserts and cells were stimulated with TNFα or a combination of TNFα, IL1β, and VEGF...

Sixty pullets, aged 17 weeks, were presented when presumed to be 'dead' after being exposed to wet-cold weather transportation. The birds appeared unconscious and their feathers were soaking wet, and with a body rigid and cold to touch. The aim of the study was to resuscitate the hypothermic pullets. Blood samples were obtained and core body temperature recorded before and after rewarming. The birds were resuscitated using active external rewarming technique. Blood samples revealed significant (P < 0...

Spotted fever group (SFG) rickettsiosis is caused by obligatory intracellular Gram-negative bacteria that belong to the genus Rickettsia. Ticks belonging to the family Ixodidae can act as vectors, reservoirs or amplifiers of SFG rickettsiae. This study was conducted to estimate the seroprevalence of SFG rickettsioses in cattle, sheep and goats from Khartoum State, Sudan. Blood samples were collected from a total of 600 animals (sheep, goats and cattle) from 32 different farms distributed in three locations in Khartoum State during the period January to December 2012...

BACKGROUND: Human beings have few characteristics that are unique from others. Lip prints are one of such feature. They are not changed throughout the life and are not influenced by injuries, diseases, or environmental changes. According to the various antigen-antibody reactions in the bloodstream, different individuals have specific blood groups. AIM: To study the distribution of lip print patterns among individuals with different ABO and Rh blood groups and also to know the relation between their characters and blood groups...

Our objectives were to evaluate circulating LH concentrations after intravaginal (IVG) instillation of GnRH analogs in lactating dairy cows. In 2 experiments, lactating Holstein cows (experiment 1: n = 32; experiment 2: n = 47) received the experimental treatments 48 h after the first of 2 PGF2α treatments given 12 h apart and 7 d after a modified Ovsynch protocol (GnRH at -7 d, PGF2α at -24 h, PGF2α at -56 h, GnRH at 0 h). In experiment 1, cows were stratified by parity and randomly allocated to receive the following treatments: 2 mL of saline IVG (SAL, n = 6), 100 µg of gonadorelin (Gon) i...

Amyotrophic Lateral Sclerosis (ALS) is one of the most common adult-onset motor neuron disease causing a progressive, rapid and irreversible degeneration of motor neurons in the cortex, brain stem and spinal cord. No effective treatment is available and cell therapy clinical trials are currently being tested in ALS affected patients. It is well known that in ALS patients, approximately 50% of pericytes from the spinal cord barrier are lost. In the central nervous system, pericytes act in the formation and maintenance of the blood-brain barrier, a natural defense that slows the progression of symptoms in neurodegenerative diseases...

PURPOSE: Previous studies have demonstrated that obese patients (BMI >30) undergoing laparoscopic colectomy have longer operative times and increased complications when compared to non-obese cohorts. However, there is little data that specifically evaluates the outcomes of obese patients based on the degree of their obesity. The aim of this study was to evaluate the impact of increasing severity of obesity on patients undergoing laparoscopic colectomy. METHODS: A retrospective review was performed of all patients undergoing laparoscopic colectomy between 1996 and 2013...

FUT2 is a gene for a fucosyltransferase that encodes expression of ABO blood group antigens found on gastrointestinal mucosa and secretions. We hypothesized that the fecal microbiomes of healthy subjects, with blood group antigens A, B and O, have differing compositions. Thirty-three fecal and blood specimens from healthy subjects were analyzed for FUT2 genotype and the fecal microbiome was determined using 454 pyrosequencing. Our data shows that being a blood group secretor is associated with less diversity at higher orders of taxonomy; and the presence of blood group A antigens in the secretor subjects are associated with an expansion families of bacteria within the gut...
