1. Strategies to increment in vivo and in vitro embryo production and transfer in cattle
Abstract Knowledge of follicular wave dynamics obtained through the use of real-time ultrasonography and the development of the means by which follicular wave dynamics can be controlled have provided practical approaches for the in vivo and in vitro production and transfer of embryos in cattle. The elective control of follicular wave emergence and ovulation

2. Comportamento sexual de cabras Toggenburg durante a estação reprodutiva após luteólise natural ou induzida
Proestrus (days -2 and -1), estrus (days 1, 2 and 3) and metaestrus (days +1 and +2) sexual behavior was monitored in Toggenburg females goats, during natural breeding season after induced and natural luteolysis. The females received two doses of PGF2 10-day interval, for estrus synchronization. After the first injection the estrus was monitored three times

3. Suplementação mineral e desempenho reprodutivo no período pós-parto de vacas primíparas de corte / Mineral supplementation and reproductive performance in the postpartum of primiparous beef cows
The objective of this work was evaluate the reproductive performance of primiparous beef cows, in real system of production, in the postpartum period, supplemented in a group with common mineral supplement and in another one, specific mineral supplement for reproduction. Also was evaluated the response of these females submitted to the Ovsynch protocol of sy

4. Average weight gain and reproductive performance of dairy heifers, supplemented with organic and inorganic minerals / Ganho mÃdio de peso e desempenho reprodutivo de novilhas leiteiras suplementadas com minerais orgÃnicos e inorgÃnicos
50 novilhas leiteiras foram divididas em dois grupos de acordo com a fonte mineral suplementada: Tratamento OrgÃnico (T1, n=25) e Tratamento InorgÃnico (T2, n=25). Estas foram suplementadas por 10 meses (julho/2004 a abril/2005), realizando-se trÃs experimentos dentro desse intervalo. Exp. 1: os animais tiveram seus pesos estimados com fita durante os 10

5. Accumulation of a Protein Required for Division During the Cell Cycle of Escherichia coli
A heat-labile protein required for division accumulates during the duplication cycle of Escherichia coli. Its formation appears to commence shortly after the cell divides, and it reaches a maximal amount shortly before the next division. A plausible mechanism for timing cell division depends on building up the critical amount of this protein. Completion of d

6. TEMPERATURE LIMITS, GENEALOGICAL ORIGIN, DEVELOPMENTAL COURSE, AND ULTIMATE FATE OF HEAT-INDUCED FILAMENTS IN ESCHERICHIA COLI MICROCULTURES
Hoffman, Heiner (New York University, New York, N.Y.) and Michael E. Frank. Temperature limits, genealogical origin, developmental course, and ultimate fate of heat-induced filaments in Escherichia coli microcultures. J. Bacteriol. 85:1221–1234. 1963.—The heat induction of filaments in microcultures of Escherichia coli occurred through a wide range of te

7. The Circadian Oscillator Coordinates the Synthesis of Apoproteins and Their Pigments during Chloroplast Development.
Greening has been studied at circadian times of maximal and minimal levels of mRNA for the light-harvesting chlorophyll a/b binding protein in photosystem II (Cab mRNA) after circadian synchronization of etiolated barley plantlets (Hordeum vulgare cv Apex) by heat-shock treatments. It was found that greening occurs faster and without a lag period when illumi

8. Identification of Proteins Whose Synthesis Is Modulated During the Cell Cycle of Saccharomyces cerevisiae
We examined the synthesis and turnover of individual proteins in the Saccharomyces cerevisiae cell cycle. Proteins were pulse-labeled with radioactive isotope (35S or 14C) in cells at discrete cycle stages and then resolved on two-dimensional gels and analyzed by a semiautomatic procedure for quantitating gel electropherogram-autoradiographs. The cells were
