Lead (Pb) is one of the most hazardous heavy metal that caused serious problems for ecosystem at recent years. In this study, the effect of Pb on seed germination, incipient growth and antioxidant enzymes of six common used turfgrasses was investigated. The results showed that after implementation of different concentrations (0, 1000, 2000 and 3000 µM) of Pb, Agropyron elongatum exhibited the h...
Introduction For cold-blooded or poikilothermic animals, winter presents challenges to survival. Since the body temperature (Tb) of poikilotherms is usually very close to that of their surrounding environment, the risk of death from freezing is very real when temperatures drop below 0°C. Food is also scare during the winter and some animals also have limited mobility because the cold can make m...
In China, the health impact of cold weather has received little attention, which limits our understanding of the health impacts of climate change. We collected daily mortality and meteorological data in 66 communities across China from 2006 to 2011. Within each community, we estimated the effect of cold spell exposure on mortality using a Distributed Lag Nonlinear Model (DLNM). We also examined...
Zoysiagrass, the most cold-tolerant grass among the warm-season turfgrasses, is often used as a model species for isolating cellular components related to cold stress. To understand the proteomic responses to cold stress in zoysiagrass stolons, we extracted stolon proteins from Zoysiajaponica, cv. Meyer (cold-tolerant) and Z. metrella, cv. Diamond (cold-sensitive), which were grown with or with...
The asthmatic response to the common cold is highly variable, and early characteristics that predict worsening of asthma control following a cold have not been identified. In this prospective multicentric cohort study of 413 adult subjects with asthma, the mini-Asthma Control Questionnaire (mini-ACQ) was used to quantify changes in asthma control and the Wisconsin Upper Respiratory Symptom Surv...
Studies on daily rhythmicity in livestock under natural conditions are limited, and there is mounting evidence that rhythm patterns differ between chronobiological studies conducted in the laboratory and studies conducted under pronounced natural seasonality. Here, we investigated the influence of cold-dry (harmattan) and hot-dry seasons on daily rhythmicity of rectal (RT) and body surface temp...
Introduction Influenza poses a global health threat. The disease affects all ages, often with variable clinical features. Abidjan, where this study took place, has a long rainy season AprilJuly with a shorter less intense rainy season October-November. Temperatures vary very little during the year. In temperate areas, children and adults aged 65 years are risk groups. In these countries the sea...
Sir,?Will any one of the numerous readers of your esteemed journal please come forward with an explanation of the following I have noticed in several dispensaries in South Sylhet Subdivision that about 75 per cent, of the patients visiting outdoor dispensaries during the cold season for stomatitis suffer at the same time from scrotal eczema, and the cure of one of the conditions is followed by ...
person. Several years previously I had seen him, and had then passed instruments up to No. 10. Ho was suffering from an irritable stricture, partly organic, but greatly aggravated by muscular spasm. Again, during the rainy season of 1868, I had seen hitn when in similar trouble, and wa9 unable to introduce any instrument owing to the extremely irritable state of the stricture. He was exceedingl...
We study the determinants of season of birth of the first child, for White non-Hispanic married women aged 25-45 in the US, using birth certificate and Census data. The prevalence of good season (quarters 2 and 3) is significantly related to mother's age, education, and smoking status during pregnancy, as well as to receiving WIC food during pregnancy and to pre-pregnancy body mass index. Moreo...
