Evidence suggests that egg intake may be implicated in the aetiology of sex hormone-related cancers. However, dose-response relationships between egg intake and such cancers are unclear. Thus, we conducted a dose-response meta-analysis to summarise the dose-response relationships between egg consumption and the risk of breast, prostate and gynaecological cancers. A literature search was perform...
Objectives: To examine the performance of a rural ambulance trust during two time periods, 1996/97 and 2001, with respect to achieving standards for ambulance journey times and delivery of clinical care for patients with suspected acute myocardial infarction (AMI). Methods: Audit datasets on two cohorts of patients with chest pain and suspected AMI were assembled by the Lancashire Ambulance Ser...

The main antivirals employed to combat seasonal and pandemic influenza are oseltamivir and zanamivir which act by inhibiting the virus-encoded neuraminidase. These have to be deployed close to the time of infection and antiviral resistance to the more widely used oseltamivir has arisen relatively rapidly. Defective interfering (DI) influenza virus is a natural antiviral that works in a differen...
In the computational geometry field, simplicial complexes have been used to describe an underlying geometric shape knowing a point cloud sampled on it. In this article, an adequate statistical framework is first proposed for the choice of a simplicial complex among a parametrized family. A least squares penalized criterion is introduced to choose a complex, and a model selection theorem states ...
HLA-DRB1, especially the shared epitope (SE), is strongly associated with rheumatoid arthritis (RA). However, recent studies have shown that SE is at most weakly associated with RA without anti-citrullinated peptide/protein antibody (ACPA). We have recently reported that ACPA-negative RA is associated with specific HLA-DRB1 alleles and diplotypes. Here, we attempted to detect genetically differ...
چکیده : بخش اول : دراین تحقیق،ترکیب نانو بوراکس با استفاده از دستگاه آسیاب ماهواره ای سنتز شده و مورد بررسی قرار گرفت. فرمول کلی این ترکیب به صورت na2[b4o5(oh) 4].8h2oیا na2b4o7.10h2o می باشد. این ترکیب با استفاده از روش طیف سنجی مادون قرمز (ir) شناسایی شد و همچنین اندازه و ساختار نانو ذرات سنتز شده به وسیله آنالیز پراش پرتو ایکس (xrd) و مورفولوژی سطح و ساختاری نمونه تهیه شده توسط میکروسکوپ ا...

A grade-separated crossing allows a bicycle/pedestrian to continue over or under barrier without conflict with vehicle. However, the serviceability of these facilities is compromised in underdeveloped countries, including Pakistan. This research examines effectiveness pedestrian bridges and underpasses terms their usage by pedestrians. total 80,017 crossings were observed at four sites (3 overh...
