Birthweight and semen characteristics [PDF]
A correlation between birthweight and sperm counts in adult life was anticipated because impaired fetal growth could impair replication of Sertoli cells produced in fetal life. Furthermore, it was expected that males born with a high birthweight might have impaired sperm production as they are expected to have been exposed to higher levels of oestrogen

The authors state that sperm apoptosis is a useful indicator of male infertility in the case of varicocele, while being unable to detect Fas and Fas-L on sperm cells. At the same time, they also claim that the presence of Fas is a debated issue. We demonstrated beyond any reasonable doubt that Fas is not present in human sperm and clarified that ...

In view of the well known sensitivity of the seminiferous epithelium to various stress factors and to chemicals one would expect that semen analyses would be part of many screening programs to detect dangerous chemicals and environmental hazards. This is not the case, and our knowledge about the production and functional properties of human spermatozoa

Quality of Semen Stored in On-the-Farm Semen Tanks
We assessed the damage to frozen semen packaged in French straws stored for 2 yr in 60 on-the-farm semen tanks on 56 Washington dairy farms. Percentage of motile spermatozoa and percentage of spermatozoa with intact acrosomes were not affected significantly by position of the semen on the rack (top or bottom goblet).

Semen Quality in Relation to Semen Preservation
A goal of research in laboratory evaluation of semen has been ultimately to predict the fertility achievable with use of that semen. This would permit evaluation of the male and ejaculate. For artificial insemination, semen viability becomes a measure of man's interaction with that semen in an effort to preserve its functional life. Man's efficiency in

The unpredictably eruptive dynamics of spruce budworm populations in eastern Canada
We examine historical population data for spruce budworm from several locations through the period 1930–1997, and use density‐dependent recruitment curves to test whether the pattern of population growth over time is more consistent with Royama's (1984; Ecological Monographs 54:429–462) linear R(t) model of harmonic oscillation at Green River New ...

FoxO1 signaling in B cell malignancies and its therapeutic targeting
FoxO1 has context‐specific tumor suppressor or oncogenic character in myeloid and B cell malignancies. This includes tumor‐promoting properties such as stemness maintenance and DNA damage tolerance in acute leukemias, or regulation of cell proliferation and survival, or migration in mature B cell malignancies.
