The crystal structure of integrin alphavbeta3 comprises 3 regions of contact between alphav and beta3. The main contact on alphav is located in the beta-propeller while calf-1 and calf-2 domains contribute minor interfaces. Whether or not contacts between calf-1 and calf-2 domains of glycoprotein (GP) IIb (alphaIIb) and GPIIIa (beta3) play a role in GPIIb/IIIa complex formation has not been est...

Peripheral tissue oxygenation has been studied with near-infrared spectroscopy (NIRS) on either the forearm or calf with questionable comparability. The aim was to compare forearm and calf tissue oxygenation in healthy term neonates measured with NIRS. Fractional oxygen extraction, tissue oxygenation index, and mixed venous oxygenation were similar in both extremities, whereas oxygen delivery a...

Effect of dystocia, breeding group, cow age and calf sex on periand early postnatal (within 24 hr. after birth) mortality was studied. Data obtained from 1967 to 1972 included 5,064 parturitions from 18 breeding groups. Approximately 35% of the parturitions were from 2,year-old cows, 24% from 3-year-olds and 41% from cows 4 years and older. Type of parturition was divided into four classificati...

The properties of the microsomal vitamin K-dependent carboxylase from the livers of the adult ox and dicoumarol-treated calf were investigated. The enzymes from both sources utilized glutamic residues of synthetic peptides as substrates and could be solubilized with Triton X-100 similarly to the enzyme from vitamin K-deficient rat liver. Under the optimal assay conditions, the microsomes from c...

The scale of sexed semen use to avoid the birth of unwanted bull calves in the UK dairy industry depends on several economic factors. It has been suggested in other studies that calf gender may affect milk yield in Holsteins- something that would affect the economics of sexed semen use. The present study used a large milk recording data set to evaluate the effect of calf gender (both calf born ...

Recently, high-flexion knee implants have been developed to provide for a large range of motion (ROM>120 degrees ) after total knee arthroplasty (TKA). Since knee forces typically increase with larger flexion angles, it is commonly assumed that high-flexion knee implants are subjected to larger loads than conventional knee implants. However, most high-flexion studies do not consider thigh-calf ...

Background: Heavy metals contaminated environment constitutes a serious problem for human and other organisms. Moreover, metals such as Cd, Pb, and Cr are toxic metals. Therefore, the purpose of this study was to evaluation of Cd, Pb, and Cr in the muscle of cow, calf, and sheep slaughtered in Sanandaj city from Iran. Methods: This was a descriptive cross-sectional study in Sanandaj city in...
