INTRODUCTION Park amenities promote visitation and physical activity during summer. Physical activity declines during winter. Identifying park amenities that promote visitation during winter would increase year-round activity. The purpose of this study was to determine how park visitation, amenity choice, and physical activity intensity change across seasons. METHODS Physical activity intensi...

CDC collects, compiles, and analyzes data on influenza activity year-round in the United States (http://www.cdc.gov/flu/weekly/fluactivitysurv.htm). The influenza season generally begins in the fall and continues through the winter and spring months; however, the timing and severity of circulating influenza viruses can vary by geographic location and season. Influenza activity in the United Sta...

OBJECTIVE although numerous studies have reported the association between birth season and sex ratio, few studies have been conducted in subtropical regions in a non-Western setting. The present study assessed the effects of pregnancy season on birth sex ratio in China. METHODS We conducted a national population-based retrospective study from 2006-2008 with 3175 children-parents pairs enrolle...

Based on the epidemiological finding that individuals with schizophrenia tend to be born in winter/spring when compared to the general population, we examined (1) the strength and timing of this effect in Northern Hemisphere sites, and (2) the correlation between the season of birth effect size and latitude. Studies were located via electronic data sources, published citations, and letters to a...

The purpose of this study was to investigate the rate of age-related maculopathy among elderly males and females in relation to frequency of consumption of fresh vegetables and fruit. During ophthalmological investigation of Kaunas city inhabitants aged 65-74 years (240 males and 206 females) age-related maculopathy (early and late) was determined for 22.1% of males and 20.4% of females. Freque...

Sea surface partial pressure of carbon dioxide (pCO2) is an important parameter in the ocean carbon cycle system. By using accurate global sea surface pCO2 data, we can directly estimate the ratio of net CO2 uptake of global ocean, which can provide a support for further research of global carbon cycle. This article mainly discussed the seasonal changes of sea surface pCO2 and the relationships...

Background: Soil and plant contamination in copper exposure causes chronic copper poisoning (CCP) in animals following the consumption of plants in these soils. Objectives: The present study was carried out on 10 clinically affected copper poisoned cases (in each season) from autumn 2015 to the end of summer 2016, in four seasons in Kerman province to evaluate the seasonal effects of CCP in she...

The correlation between season (fall, winter, spring, and summer) and infection rate in surgical patients is well defined in many specialties. To the authors' knowledge, there are no data in the literature on this phenomenon in patients undergoing total joint arthroplasty. They hypothesized that there would be an increased infection rate in the summer months in patients undergoing elective tota...

To understand the influence of trans-boundary air pollution on the air quality of Fukuoka, the mass concentration and chemical composition of fine particulate matter (PM) were observed at urban (Fukuoka) and rural (Fukue Island) sites in the northern Kyushu area in Japan. Chemical composition was measured using an aerosol mass spectrometer. Organic aerosol (OA) data were analyzed by the positiv...

this study has been conducted in the slaughter- house of the city of kerman, for one year, starting march 1993. a total number of 16402 livestocks including 5013 sheep, 8163 goats and 3226 cattle were examined in a regular manner, 120 days, with a mean of 30 days per season. after recording the king, sex and origin of each animal, liver and lungs were examined carefully for hydatid cyst. in gen...
