STEALTH is a method for using some artificial intelligence-generated models without suffering from malicious attacks or associated unfairness issues. asks so few queries (one per data cluster) that algorithms cannot detect its operation know when to lie.

The increase in interfollicular epidenmal nibosomes on the backs of mice initiated with 7,12-dimethylbenz(a)anthracene and promoted with 12-O-tetradecanoyl-phambol 13-acetate was disproportionate to the increase in epi dermal wet weight, protein, and DNA. Whereas mibosame numbers increased fiveto sixfold 48 hr after the first, fourth , or eighth application of 12-O-tetradecanoyl-pharbal 13-acet...

OBJECTIVE To assess the knowledge of four groups of individuals regarding who is legally authorised to consent to health care or research involving older patients. DESIGN A provincewide postal survey. SETTING Province of Quebec, Canada. PARTICIPANTS Three hundred older adults, 434 informal caregivers of cognitively impaired individuals, 98 researchers in aging and 136 members of research ...

SUMMARY Acute and chronic effects of gonadotropin releasing hormone (GnRH) administration on reproductive characteristics of 32 rams have been assessed during the nonbreeding season. Rams injected intramuscularly with 50 /ag of GnRH had elevated (P<.01)concentrations of serum testosterone and noticeably higher (60%) mating activities when compared to control animals injected with saline. Daily ...

A utophagy is a process by which cellular components are captured into organelles called autophago-somes and then brought to the lysosome or vacuole to be broken down and recycled for other uses. It frequently comes into play during starvation, allowing cells to survive periods of privation. Yoshinori Ohsumi survived privation while growing up in post–World War II Ja-pan and struggled to establ...

observations, to constrain the pattern of N2 fixation across the Pacific Ocean. N2 fixation introduces isotopically light atmospheric N2 from to the ocean (d N = 0‰) relative to the oceanic average near 5‰, which makes nitrogen isotopes suitable to infer patterns of N2 fixation. Including atmospheric iron limitation of diazotrophy in the model shifts the pattern of simulated N2 fixation from th...

The hydroxylating activities of liver microsomes for proges terone and testosterone were markedly decreased in male and female rats bearing Walker carcinosarcoma 256. The decreases in the hydroxylating activities were greater in the male rats than in the female rats. The content of cytochrome P-450 in liver microsomes was decreased in the tumor-bearing male and female rats. Moreover, the bindin...
