چکیده
Pasco et al (pp. 322–326) investigated the role of tobacco smoking as a risk factor for major depressive disorder, using data from an Australian population-based sample of women. They found both cross-sectional and longitudinal evidence for an association between smoking and depression, particularly among heavy smokers. Using a range of brain imaging techniques, de Win et al (pp. 289–296) found evidence of specific thalamic changes among ecstasy users, even after account was taken of the potential confounding effects of poly-drug use. The authors concluded that ecstasy use appears to decrease serotonergic function via a specific toxic effect on serotonergic axons in the thalamus.

Identification of insulin intermediates and sites of cleavage of native insulin by insulin protease from human fibroblasts.
We have studied the time sequence degradation of native insulin by insulin protease from human fibroblast using multiple steps involving purification of the products by high performance liquid chromatography, determination of peak composition by amino acid sequence analysis, and confirmation of structure by mass spectrometry and thus elucidated the sites of cleavage of insulin by human insulin ...
متن کاملEffect of chromosome substitution on intrinsic exercise capacity in mice
Previous research identified a locus on Chromosome 14 as an important regulator of endurance exercise capacity in mice. The aim of this study was to investigate the effect of chromosome substitution on intrinsic exercise capacity and identify quantitative trait loci (QTL) associated with exercise capacity in mice. Mice from a chromosome substitution strain (CSS) derived from A/J and C57Bl/6J (B...
متن کاملFermat’s Test
Fermat’s little theorem says for prime p that ap−1 ≡ 1 mod p for all a 6≡ 0 mod p. A naive extension of this to a composite modulus n ≥ 2 would be: for a 6≡ 0 mod n, an−1 ≡ 1 mod n. Let’s call this “Fermat’s little congruence.” It may or may not be true. When n is prime, it is true for all a 6≡ 0 mod n. But when n is composite it usually has many counterexamples. Example 1.1. When n = 15, the t...

متن کاملFunctional Architecture of RNA Polymerase I
Synthesis of ribosomal RNA (rRNA) by RNA polymerase (Pol) I is the first step in ribosome biogenesis and a regulatory switch in eukaryotic cell growth. Here we report the 12 A cryo-electron microscopic structure for the complete 14-subunit yeast Pol I, a homology model for the core enzyme, and the crystal structure of the subcomplex A14/43. In the resulting hybrid structure of Pol I, A14/43, th...
