We report two rare cases of adult-onset phalangeal microgeodic syndrome (PMS), which commonly develops in children. Both cases were Japanese women, with case 1: 60 years old and case 2: 58 years old. They developed swelling and stiffness in their fingers in winter, and their symptoms disappeared without any treatment in summer. Magnetic resonance imaging (MRI) of bilateral hands showed diffuse ...

The present investigation was carried out to evaluate the effects of environmental factors on reproductive performance of bovine (Bos taurus) during summer, winter and spring for one year. The study was performed on free moving animals under natural condition during the two consecutive estrus periods by visual observation. The duration of estrus, numbers of mounts were observed. There was a sea...

Background & Aims of the Study: The current study was designed to determine the quality of sediments in Karun in Ahvaz, Iran, according to aquatic pollution indices. Materials and Methods: The sediment samples were obtained from six river stations in summer and winter. The sediment samples were air-dried, sifted, homogenized, and stored in plastic bags, and the concentrations of metals were...

This paper presents monitoring data on levels of aflatoxin M1 in the farm-gate milk in Albania. The monitoring included 120 evenly distributed samples collected in winter and summer from various farms all over the country. The levels of aflatoxin M1 were determined using the quantitative thin layer chromatography. On average, the winter milk samples revealed higher concentrations of aflatoxin M...

Light absorption coefficients of black carbon ( abs B ) were measured at several urban and industrial locations in Jordan during the summer of 2007 and the winter of 2008 using the photoacoustic instrument at a wavelength of 870 nm. Black carbon mass concentration (BC) was calculated using abs B . Black carbon levels at urban locations in the summer of 2007 were higher than those obtained at in...

This study aimed to compare the dynamics of air temperature and velocity under two different ventilation and housing systems during summer and winter in Korea. The NH3 concentration of both housing systems was also investigated in relation to the pig's growth. The ventilation systems used were; negative pressure type for the enclosed pig house (EPH) and natural airflow for the conventional pig ...

Arabian babblers (Turdoides squamiceps; mean adult body mass=72.5 g) inhabit extreme deserts of Israel. Previous studies have shown that their daily field metabolic rates are similar in winter and summer and that there is an increase during the breeding season. We hypothesized that the difference in seasonal daily field metabolic rate would be a consequence of differences in daytime metabolic r...

 The Indian riverine buffaloes are more susceptible to variations in the environment. These variations affect seminal plasma proteins, which in turn affect fertility. This study was conducted to evaluate variations in the Indian Bubalus bubalis seminal plasma protein profile using two-dimensional polyacrylamide gel electrophoresis (2D-PAGE) during winter and summer seasons, and its relation wit...
