PURPOSE There is limited epidemiological evidence of food hypersensitivity (FH) in the adult population. We aimed to determine the prevalence of FH in Mexican adults, their clinical features and to establish common food involved in its appearance. METHODS We designed a cross-sectional study using a fixed quota sampling; 1,126 subjects answered a structured survey to gather information related...
background and objective: neisseria meningitidis is a leading cause of meningitis and sepsis worldwide. the factor h binding protein (fhbp) is a key virulence factor of neisseria meningitidis that is able to selectively bind to human factor h, the key regulator of the alternative complement pathway, which it has important implications for meningococcal pathogene- sis and vaccine design. the aim...
OBJECTIVE A positive family history (FH) is a risk factor for late-onset Alzheimer's disease (AD). Our aim was to examine the effects of FH on pathological and neuronal loss biomarkers across the cognitive spectrum. DESIGN Cross-sectional analyses of data from a national biomarker study. SETTING The Alzheimer's Disease Neuroimaging Initiative national study. PATIENTS 257 subjects (ages 55...
BACKGROUND Familial hypercholesterolemia (FH) is a common autosomal dominant disorder, characterized by a high level of low-density lipoprotein cholesterol (LDL-C) and a high risk of premature cardiovascular disease. OBJECTIVE To evaluate clinical and anthropometric characteristics of patients with the familiar hypercholesterolemia (FH) phenotype, with or without genetic confirmation of FH. ...
Factor H (fH) is an important regulator of the alternative complement cascade. Several human pathogens have been shown to bind fH to their surface, a process that facilitates immune evasion or cell to cell interaction. Among the pathogens that bind fH are some Borrelia species associated with Lyme disease and relapsing fever. The fH-binding proteins of the Lyme spirochetes form two classes (I a...
Vascular endothelial cells (ECs) link hemostasis, thrombosis, and complement. ECs synthesize both the clotting initiator von Willebrand factor (VWF) and the complement regulator factor H (FH). VWF is stored in EC Weibel-Palade bodies (WPBs), but the intracellular location of FH is not well defined. We found that FH colocalizes with VWF in WPBs of human umbilical vein ECs. Moreover, FH bound to ...
T follicular helper (T(FH)) cells are central to the development and regulation of T cell-dependent humoral immune responses. The transcriptional repressor BCL6 is required for T(FH) responses, but the kinetics of BCL6 protein expression in activated CD4(+) T cells have not been established. We measured BCL6 expression during T(FH) cell development at the single-cell level using intracellular s...
Transcription activator-like effector nucleases (TALENs) are valuable tools for precise genome engineering of laboratory animals. Here we utilized this technique for efficient site-specific gene modification to create a fumarate hydratase (FH) gene knockout rat model, in which there was an 11 base-pair deletion in the first exon of the FH gene in 111 rats. 18 live-born targeted mutation offspri...
The hypothesis that respiratory modulation of heart rate variability (HRV) or respiratory sinus arrhythmia (RSA) is restricted to mammals was tested on four Antarctic and four sub-Antarctic species of fish, that shared close genotypic or ecotypic similarities but, due to their different environmental temperatures, faced vastly different selection pressures related to oxygen supply. The intrinsi...
زمینه و هدف: تست حداکثر ظرفیت ورزشی می تواند به عنوان یک تست تشخیصی در بیماران با مشکلات قلبی و عروقی بدون علائم کلینیکی در نظر گرفته شود. کمبود هورمون های تیروئیدی در دوره جنینی می تواند منجر به کاهش عملکرد سیستم قلبی عروقی شود. هدف از این مطالعه، ارزیابی میزان حداکثر ظرفیت ورزشی در زاده های بالغ مبتلا به هیپوتیروئیدی جنینی (FH)در موش صحرائی میباشد. روشها: FH بوسیله اضافه کردن داروی پروپیل...
