BACKGROUND Recent studies suggest that placenta may harbour a unique microbiome that may have origin in maternal oral microbiome. Although the major physiological and hormonal adjustments observed in pregnant women lead to biochemical and microbiological modifications of the oral environment, very few studies evaluated the changes suffered by the oral microbiota throughout pregnancy. So, the ai...

The impact of ultrasonography on the practice of obstetrics has been profound. A carefully performed sonographic examination reveals vital information about fetal anatomy, as well as fetal environment, growth, and well-being. Technology has evolved from producing two-dimensional images of the pregnant uterus to using Doppler methods for measurement of maternal and fetal circulation and to creat...

One of the main goals of small, medium and large farms is to improve the reproductive performance of rabbit does. Stocks of lower productivity can be improved by crossing with intensive breeds. A better nutritional status of both foetuses and suckling kits has a positive effect on their later productivity. Overfeeding young females before first mating can lead to conditions of fattiness. Using ...

Multispectral images of the lunar western limb and far side obtained from Galileo reveal the compositional nature of several prominent lunar features and provide new information on lunar evolution. The data reveal that the ejecta from the Orientale impact basin (900 kilometers in diameter) lying outside the Cordillera Mountains was excavated from the crust, not the mantle, and covers pre-Orient...

A study was conducted over a 2-mo period to compare estrus detection results obtained using an androgenized teaser mare with those obtained with a stallion, using the same group of 10 normally cyclic mares. The teaser mare was androgenized by administration of boldenone undecylenate (500 mg i.m. every 1 to 2 wk), and allowed to run loose with the mare group. Estrus was determined by observation...

LENGEROVA (1957) obtained indirect evidence that placental permeability to transplantation antigens could be induced in the rat by delivering 200 r. of X-irradiation to the pregnant uterus on the 15th day of gestation. The young were found subsequently to be immunologically tolerant of grafts of maternal skin. The passage of transplantation antigens into the foetus in sufficient quantity to ind...

One hundred and fifty ewes with lifetime records of ovulation rate and lambing were divided into two groups on the basis of age, live weight and reproduction index (calculated from reproductive performance data). Both groups were synchronised in oestrus with progestagen sponges inserted for 14 days. At sponge removal one group received no PMSG while the other group received 400 i.u. PMSG. Eight...

With aim to solve mentioned problems we undertake the induction and synchronization of estrus's by use of "Crestar" (Intervet) preparation in combination with PMSG (Subotica) and prostaglandin's Sinhrogal (ICN Galenika) according to producers recommendation. On the dairy farm 115 cows was treated separately in 4 groups (25, 25, 25 and 40 cows), while on the beef farm were 370 cows in 4 groups (...

Arteriovenous malformation of the pregnant uterus is very rare, and may present with unexplained torrential bleeding. We report a patient with absence of the conventional risk factors, and was saved by quick recourse to hysterectomy to control the bleeding.

This paper reports a case of super pregnancy in a BALB/c mouse pregnant with 30 pups following induction of superovulation using a PMSG-hCG protocol. Superovulation was induced in 10 mice by injecting 5 IU PMSG followed by 5 IU hCG 48 hours later. Immediately after injection of hCG, animals were placed with males at a ratio of 1 to 1 for 24 hours. On day 14 after mating, animals were killed by ...
