The overall twinning rate was shown to increase from .6% in the first parity to 4.0% in the sixth parity, and a positive phenotypic trend for twinning rate was observed during the time period considered (1978 to 1995). The distribution of bulls according to the average percentage of multiple births of daughters in first and second parity showed that some bulls had an extremely low twinning freq...

Data collected from Jersey herd in the central highland environment of Ethiopia was used to estimate genetic parameter and trend analysis for reproductive/fertility traits. Totally, 11,933 reproductive records recorded during last 30 years were analysis. Traits studied NSC (number service per conception), DO (days open), CI (calving interval), AFC (age at first calving) AFS service). Genetic ph...

BACKGROUND The purpose of this study was to evaluate the effects of benzalkonium (BAK)-free travoprost monotherapy administered for 3 years on intraocular pressure and visual field performance. METHODS The intraocular pressure of 76 patients with normal tension glaucoma was monitored every 1-3 months. A Humphrey visual field test was performed every 6 months after treatment and compared with ...

although candida albicans is the most common etiologic agent of candidiasis, c. dubliniensis, has been emerged, as another pathogen resembles c. albicans in many phenotypic aspects and noted for its in vitro potential for fluconazole resistance. since there was no evidence of any report about detection of this organism in iran, this study was designed to use of five different tests for identifi...

BACKGROUND Sensors detect the rate and direction of glucose trend. They need to be accurate and reproducible as could be evidenced by strong agreement between multiple sensors. We evaluated this relationship through simultaneously worn glucose sensors using several methods of slope analysis. METHODS Ten type 1 diabetic, insulin pump-treated subjects were studied while simultaneously wearing t...

Genetic and phenotypic (co)variances for mature equivalent yield of 4% FCM and calving interval were simultaneously estimated by REML for grade Holstein cows in first and second parity. Data were 305d mature equivalent lactation records and calving dates for 299,441 daughters of 2489 AI sires first calving from 1970 to 1985 in California, New York, or Texas. Data were divided into three time pe...

Background & objectives: Fungal infections are increasing very rapidly. Candida is a major pathogen involved and constitutes a part of normal microflora of humans. This organism is a leading agent associated with blood stream infections. The present study involves phenotypic characterization of Candida isolates. The isolates were obtained from National Culture Collection of Pathogenic Fungi at ...

Records collected during 1971 through 1979 from 101,606 pigs raised in 18 herds that were members of the Nebraska SPF Swine Accrediting Association were evaluated for phenotypic trends and predicted and observed genetic trends. Traits considered were backfat at 100 kg (BF) and weight at 140 d of age (WT). Phenotypic change on average was beneficial for BF (-.05 mm/yr) but undesirable for WT (-....

Recent climate change has been linked to shifts in the timing of life-cycle events in many organisms, but there is debate over the degree to which phenological changes are caused by evolved genetic responses of populations or by phenotypic plasticity of individuals. We estimated plasticity of spring arrival date in 27 species of bird that breed in the vicinity of an observatory in eastern North...

Macrophysiology is defined as the study of variation in physiological traits-including physiological trait flexibility-over large geographical and temporal scales, and the ecological implications of this variation. A classic example of a macrophysiological trend is the one emerging from the climatic variability hypothesis, which states that as the range of climatic fluctuation experienced by te...
