Intermittent claudication is an occasional side effect of beta-adrenergic blockade' but clinical details are lacking. Beta-blocking agents may exacerbate intermittent claudication in patients with severe peripheral arterial insufficiency.2 The following cases suggest that they may also provoke claudication in patients with previouslv asymptomatic peripheral arterial disease. Case 1 A man aged 5...

A population assessment of the western gray whale (Eschrichtius robustus) was conducted using photoidentification data collected off Sakhalin Island under the joint Russia-U.S. programme from 1994 to 2006. This is an update of the assessments by Reeves et al (2005) and Cooke et al. (2006) which used data up to 2003 and 2005 respectively, fitted to the same, individually-based population model. ...

An experiment was conducted in early lactating buffaloes for the period of 3 months in Jadakheria and Polisimal village of LimkhedaTaluka in Dahod district of Gujarat to assess the effect of supplementation of bypass fat on milk production, composition, body weight change and economic efficiency. Forty buffaloes in their 2nd and 3rd lactation were equally divided in completely randomized design...

Heifer development depends on nutritional management decisions throughout all growing phases. Optimizing costs to raise heifers improves profitability of dairy farms. Feed costs for heifers make up 50% of heifer costs. Required growth rates depend on the desired age at first calving and estimated mature body weight. Intensive milk feeding improves calf growth and subsequent milk production. Pre...

Gestation length, birth weight calving difficulty, calf mortality rate at birth, calf mortality rate from birth to weaning, preweaning calf growth rate and calf 200-d weight were evaluated in a biological type study in which four sire breeds were bred by AI to Hereford dams. Angus and Red Poll sires represented breeds of medium size, and Pinzgauer and Simmental sires represented large breeds. A...

Replicated cow herds of 15 Angus x Hereford (AH) and 15 Brahman x Hereford (BH) F1 cows each were placed on native rangeland (NR) or native rangeland-complementary forage (NRCF) systems. The NR was 8.1 ha of sagebrush-mixed prairie per cow-calf unit and the NRCF used the same mixed prairie complemented by .4 ha of double-cropped winter wheat and summer annual forage replacing about 30% of the m...

This review presents genetic, phenotypic, environmental and other factors influencing functional longevity in dairy cattle. High yielding cows show a lower risk of culling than low producing cows. Cows with a lower milk yield have an approximately 2.7 times greater risk of culling as compared to cows with an average milk production. Genetic estimation of the length of productive life is possibl...

We prospectively evaluated 46 patients who had intrahisian conduction delay. Twenty-three had a split His potential and 23 had a prolonged HV interval with a normal QRS complex. In those with a split His, the interval between the two His potentials averaged 32.7 msec (range 9-90 msec); in nine patients this split His was demonstrated only by atrial pacing. The 20 patients from this group with 1...
