background: human chorionic gonadotropin (hcg) has been used as a replacement for the mid-cycle luteinizing hormone (lh) surge for several years. the recent arrival of recombinant dna technology has made recombinant hcg (rhcg) accessible. objective: to assess efficacy of rhcg compared to urinary hcg (uhcg) for triggering of ovulation and induction of final oocyte maturation in assisted reproduc...

In China, grape is one of the top five fruit crops for both bearing acreage and production. Recently, national production has been stalling because an increase in drought events. order to combat adverse effects on production, it imperative understand historical trend frequency during growing season. this study, we focused agricultural four growth periods grape: bud break-flowering, flowering-ve...

Mie's theory was used to develop a theoretical model describe light propagation in apple tissue based on its microstructural properties. Taking into account the size distributions and volume fractions of intercellular space starch granules, which are known detail from previous studies, predicted decrease effective scattering coefficient μ′s about 30 % during maturation. For lateral change withi...

Objective: To study growth and skeletal maturation in children with type 1 diabetes mellitus (T1DM). Methods: We prospectively studied the anthropometric data of 56 children with T1DM at our tertiary care teaching hospital. Height was re-measured at one year to assess height velocity. A plain radiograph of the left hand was obtained for assessment of skeletal maturation. Glycosylated haemoglobi...

This review examines the evidence for the maturation of memory function during childhood using event-related brain potentials (ERP), and behavioral measures. It has been shown that brain structures implicated in different forms of memory mature during the first and into the second decade of life. Whereas the maturation rates of implicit and explicit memory have not been directly assessed in the...

Attempts on artificial maturation of European eel (Anguilla anguilla) have largely been unsuccessful. The moment of stimulation of final maturation and ovulation is mainly based on weight increase related to the hydration response of the oocytes, which, in the European eel, is irregular. In contrast to Japanese eel, European eels show wide individual variability and much slower response to horm...

in the present study, a total of 595 specimens collected monthly in the northern part of persian gulf between november 2006 and october 2007 were examined by routine macroscopic and histological techniques. monthly changes in the gonadosomatic index showed the spawning season extended within 2 peaks, from april- may and september. the maturity stages are morphologically separated according to t...

Background: in vitro maturation (IVM) of oocytes has increasing potential applications in assisted reproductive technology (ART), during which germinal vesicle (GV) oocytes cultured in vitro to produce mature (MII arrested) ones. Although functional, IVM oocytes have low developmental competence compared to in vivo matured oocytes; possibly because IVM comprises asynchrony between nuclear and c...

The objectives of the present study were to compare the effects of a protracted and a conventional induction of parturition on the incidence of retained placenta, and to evaluate the suitability of transrectal Doppler sonography of the uterine arteries as a noninvasive method for the assessment of placental maturation. Protracted induction of labor (PIP) was precipitated in 13 cows by the admin...
