ACE inhibition in goats under fixed‐time artificial insemination protocol increases the pregnancy rate and twin births

To assess the effect of the angiotensin‐converting enzyme (ACE) inhibition on the efficiency of the fixed‐time artificial insemination (TAI), 69 goats were divided randomly into two groups: enalapril (n = 35) and control (n = 34). In the experiment, all animals underwent the protocol of fixed‐time artificial insemination for 12 days. Enalapril group received enalapril maleate dissolved in saline (Enalapril, Lab Teuto Ltda) subcutaneously at the following doses: 0.2 mg/kg/day in D0‐D2; 0.3 mg/kg/day in D3‐D6 and 0.4 mg/kg/day in D7‐D11. The control group received the corresponding volume of 0.9% saline solution. We performed a single insemination 36 hr after sponge removal using frozen semen from two adult male goats with recognized fertility. The ultrasound pregnancy diagnosis was 30 days after the artificial insemination (AI). There was significant increase in pregnancy rates and twinning as well as a decrease in foetal loss in animals receiving enalapril (p < .01). The use of ACE inhibitors during the TAI protocol was shown to be a promising alternative to increase the efficiency of such reproductive biotechnology.     

India. Disease data stolen in lab break-in

The hard drives of nine computers, containing epidemiological data gathered from around India, have been stolen from the Indian Council of Medical Research. The missing data, stored on personal computers in the council's Epidemiological and Communicable Diseases unit, include published and unpublished information collected by 16 regional centers on the incidence of AIDS, malaria, tuberculosis, and other killers. Health officials say they have no idea who stole the drives, or for what purpose.     

Thiamin deficiency in cats and dogs associated with feeding meat preserved with sulphur dioxide

Thiamin deficiency was diagnosed in cats and dogs being fed fresh minced meat, which contained sulphur dioxide as a preservative and less than 0.5 mg/kg thiamin. Thiamin in the meat and in added dietary ingredients, including a supplementary vitamin mixture, was destroyed by the sulphur dioxide.
