BACKGROUND The prevalence rates of asthma and other atopic disorders have increased steadily in many developed countries over the past few decades. Recent epidemiological and animal studies have suggested that BCG vaccination might be beneficial in reducing the subsequent development of atopy. This study investigates the relationship between asthma, allergic symptoms, atopy, and tuberculin resp...

BACKGROUND This study investigated whether pedometer-determined activity varies between summer and winter in normal-weight and overweight adults. METHODS Forty-five normal-weight (58% female, age = 39.1 ± 12.4 years, BMI = 22.2 ± 2.1 kg/m²) and 51 overweight (49% female, age = 42.1 ± 12.5 years, BMI = 29.3 ± 4.5 kg/m²) participants completed a within-subject biseasonal pedometer study. All pa...
Two proteins, a 56-kDa protein (p56) and a 58-kDa protein (p58), are produced from the hepatitis C virus (HCV) nonstructural region 5A (NS5A). Recently, we found that both proteins are phosphorylated at serine residues and that p58 is a hyperphosphorylated form of p56. Furthermore, hyper-phosphorylation depends on the production of an intact form of the HCV NS4A protein. To clarify the nature o...
Connections seem to matter both at the individual level, in terms how well a person, a firm, or a country does, as well as for the aggregate performance of the system. The advantages that accrue from connections suggest that individuals will find it attractive to invest in forming links with others. Individual connections typically have spillovers on other players. These considerations lead us ...
Genome-wide and candidate-gene association studies of bladder cancer have identified 10 susceptibility loci thus far. We conducted a meta-analysis of two previously published genome-wide scans (4501 cases and 6076 controls of European background) and followed up the most significant association signals [17 single nucleotide polymorphisms (SNPs) in 10 genomic regions] in 1382 cases and 2201 cont...
Twelve cases of suspected impaired driving are discussed in which the drivers who subsequently tested positive for synthetic cannabinoid drugs underwent a psychophysical assessment. The attitude of the drivers was described as cooperative and relaxed, speech was slow and slurred and coordination was poor. Pulse and blood pressure were generally elevated. Horizontal gaze nystagmus was assessed i...
Road traffic crashes are a significant cause of the disease burden among children, with the highest mortality in low- and middle-income countries. This observational study explores such injuries in Cape Town, South Africa through an analysis of data for cases in 1992, 2002 and 2012 at the Red Cross War Memorial Children's Hospital, a referral paediatric hospital for children younger than 13 yea...
در سال های اخیر، تلاش های زیادی برای ساخت فاز خالص (2223) از ابررسانای bi-sr-ca-cu-o با دمای بحرانی حدود k110 صورت گرفته است. همان گونه که در بسیاری از مقالات ذکر گردیده، سه فاز مختلف ابررسانایی در ابررسانای پایه bi با دمای گذار (2201)k10، (2212)k85 و (2223)k110 وجود دارد. فاز 2223 به دلیل tc بالای آن، بیشتر مورد توجه قرار دارد. گزارش گردیده که آلایش سیستم bscco به سرب با ترکیب و فرآیند گرمادهی...
A main objective of ethnobotany is to document traditional knowledge about plants before it disappears. However, little is known about the coverage of past ethnobotanical studies and thus about how well the existing literature covers the overall traditional knowledge of different human groups. To bridge this gap, we investigated ethnobotanical data-collecting efforts across four countries (Colo...
