The desired objective of controlled ovarian stimulation (COS) is to allow the growth of a cohort of follicles and to facilitate the recovery of a large number of fertilizable oocytes. However, poor responders with low ovarian reserve often fail to respond adequately despite the maximal dose of gonadotropins administered, with the results that the number as well as quality of oocytes harvested m...

The effect of suckling on post-partum ovarian function was monitored by weekly plasma progesterone determinations using enzyme immunoassay in 16 Small East African Zebu (Bos indicus) cows maintained with a fertile bull. Five cows continuously suckled their calves (COS), but starting 30 d after calving 6 cows remained with their calves which were prevented from suckling using nose plates (NOS) w...

Abstract At present, saccharides as hydrophilic matrixes, have been gradually used in amorphous solid dispersions (ASD) for dispersing poorly water-soluble drugs without surfactants. In this study, an chitosan oligosaccharide (COS) was applied a matrix to form surfactant-free ASD via the ball milling vitrify quercetin (QUE) and enhance dissolution bioavailability. Solid-state characterization (...

Bacteriophage lambda packages the DNA of the related phage 21 poorly [Hohn, B. (1975) J. Mol. Biol. 98, 93--106]. To understand the nature of the packaging defect, the interaction of the cohesive end site (cos) specific for phage 21 (cos phi 21) with phage lambda terminase has been investigated. The ability of lambda terminase to cleave cos phi 21 was studied in vitro; lambda terminase cleaved ...

BACKGROUND Although correctional officers (COs) clearly suffer from depression, positive resources for combating depression have been rarely studied in this population. The purpose of the study was to examine the associations of perceived organizational support (POS) and psychological capital (PsyCap) with depressive symptoms among Chinese COs. METHODS A cross-sectional survey was conducted i...

The theoretical basis for the link between the leaf exchange of carbonyl sulfide (COS), carbon dioxide (CO(2)) and water vapour (H(2)O) and the assumptions that need to be made in order to use COS as a tracer for canopy net photosynthesis, transpiration and stomatal conductance, are reviewed. The ratios of COS to CO(2) and H(2)O deposition velocities used to this end are shown to vary with the ...
