no clear conclusions have been made. Additionally, to maximize the success rate, more than one embryo was transferred during the ART treatment, which greatly increased the incidence of twins or multi-fetus18. However, the sex ratio at birth for...

2. Apparently inbreeding does not contribute to the maintenance of the aberrant genetic system of sex determination in natural populations of Myopus schisticolor. Keywords: inbreeding, Myopus schisticolor, sex ratio, Wood lemming. Introduction The Wood Lemming, Myopus schisticolor, and the Varying ...
Then the female would have another opportunity to conceive a daughter, or a son in better condition, provided her own condition improved in the interim. Another assumption of the Trivers-Willard hypothesis [18] is that there is minimal parental investment by the male, beyond contributing sperm. ...
In this situation, inhibition of KC resulted in a significant increase in peritoneal neutrophils, and inhibition of macrophage inflammatory protein-2 also resulted in increased peritoneal neutrophils. These results were consistent with a reverse chemotactic gradient as described by the ratio of peritoneal...
and had missing data on height or weight (n = 358). Finally, a total of 4627 participants were included to analyze the association of WCR, WC, CC, and BMI with all-cause and cause-specific mortality in older adults. Supplementary Fig.1shows a detailed description of the inclusion and...
The evolution of sexual reproduction remains a fascinating enigma in biology. Theoretically, populations of sexual organisms investing half of their resources into producing male offspring that don’t contribute to reproduction should grow at only half t
4. A transmission according to claim 2 in which said rotary thrust bearing part includes a cage and rollers mounted within said cage, said rollers presenting axes of rotation which obliquely intersect said principal axis of rotation of said transmission. ...
4. The process of claim 2 where the tube current function is modulated by varying a voltage of a part of the X-ray tube selected from the group consisting of: a control grid and a bias cup. 5. The process of claim 2 where the tube current function has a Fourier transform that has ...
