How could single-celled organisms have "sex" or even be sexually differentiated? The technical language used in the scientific press - the public and inalien- able face of 20th century science - to describe this apparently neuter organism was explicit: the cells "copulated," had "intimate ...
In a study with rats an attempt was made to measure the effect of antiandrogenic hormones on the metabolism of nonflagellate germ cells of the rat testis. Changes were observed as early as 4 days after the start of treatment. Long-term treatment with a progestin caused atrophy of the second...
In order to investigate the function of gonadal somatic cells in the sex differentiation of germ cells, we produced chimera fish containing both male (XY) and female (XX) cells by means of cell transplantation between blastula embryos in the medaka, Oryzias latipes. Sexually mature chimera fish ...
Summary This work examines the correlation between serum levels of oestrogen, progesterone and dehydroepiandrosterone sulphate (DHEA-S) and the number of human peripheral blood cells actively secreting interleukin (IL)-2, IL-4, IL-6, IL-10, tumour necrosis factor-α (TNF-α) or interferon-γ ...
1. 1. When adult White Leghorn (WL) spleen cells were injected into 15-day-old allogeneic WL embryos the splenomegaly five days later was greater in the female than in the male hosts, regardless of the sex of the donor. 2. 2. Greater splenomegaly in female hosts was also observed when...

The content of X-sex chromatin was studied in the buccal epithelial cells of pregnant women with Rh-negative blood. It was found that in women with a titer of Rh antibodies the amount of cells with X-sex chromatin decreases. A clinical-cytological correlation in the mother-placenta-fetus syst...
We characterized four novel, male- or female-specific genes and found that all are expressed mainly in the fat cells in the head. Tsx (turn on sex-specificity), sxe1 and sxe2 (sex-specific enzyme 1/2) are expressed in males, but not females, and are dependent on the known sex ...

“target” LLM answers incorrectly or until an attack limit is reached. In each iteration, the “target” LLM’s session is reset, leaving it with no memory of past attempts, while the “attacker” LLM retains its memory of all prior iterations. This iterative process provide...
