An attempt was made to induce estrus and ovulation in eight anestrus yaks by use of the Ovsynch protocol. Six out of eight yaks were successfully induced into estrus, and ovulation occurred in all the responding yaks 1-2 days after the second GnRH administration. Out of the six animals that responded to the treatment, two mated naturally with yak bulls, and calves were obtained from them. The other four animals were further administered a superovulatory regimen of Folltropin (FSH-P). Following Folltropin and Ilerin (a PGF(2alpha) analog) treatment, the animals were subjected to natural insemination. Only one animal in which natural mating occurred was flushed non-surgically for embryo recovery 7 days post-insemination. Thereafter, all the donor animals were administered with Ilerin. After 48-72 h, they came into heat and mated naturally with yak bulls, and calves were obtained from them after expiration of the normal gestation period. Following superovulation, the average numbers of palpable corpora lutea in the right and left ovaries were 2.25+/-0.6 and 1.75 +/-0.3, respectively. Three embryos were recovered by non-surgical flushing from a single animal. One embryo was transferred to a recipient yak, who produced one female calf after 258 days. This is the first report of production of a yak calf through embryo transfer-technology.

Different dermatological disorders have different effects on the lives of patients. Recently microsponge formulations have been used to treat several dermatological complications. Microsponges are basically tiny sponge like spherical particles with porous surface having valuable and attractive effect on topical delivery. The side effect of the used drug can be reduced, bioavailability can be increased, and the drug release can be modified. Microsponges can be used in different bases like gel, lotion, ointment and even in powder form. Microsponges used in sunscreen gel are now very popular. Excessive UV exposure leads to different pathological conditions like skin burns, erythema, skin carcinogenesis, etc., The microsponge sunscreen gel protects our skin from all these skin problems and most importantly, with a very less amount of side effects compared to others. Moreover, microsponges are very much cost effective, easy to handle, can deliver minimum dose of drug and enhance the stability.
