Human metaphase chromosomes A1 and A3 did bind more tritiated poly-L-lysine ([3H]PL) when they were isolated from lymphocyte cultures treated with LiCl rather than with NaCl or KCl. A2 chromosome did not show this differential behavior and in all three cases did bind more [3H]PL than the control A2 chromosome. The effect was dependent on the time of exposure of cells to the salts in tissue cult...

Caffeine, a nonselective adenosine receptor antagonist, 7-methyl-1,3-dipropylxanthine, a purported A2 selective antagonist and a 1,3-dipropyl-8-phenylxanthine amine congener (XAC), an A1 selective antagonist, were evaluated for their in vivo selectivity at A1 vs. A2 adenosine receptors. Blockade of the negative chronotropic effect of bolus i.v. injections of 2-chloroadenosine, R-phenylisopropyl...

Fluctuating asymmetry, the random deviation from perfect symmetry, is a widely used population-level index of developmental instability, developmental noise, and robustness. It reflects a population’s state of adaptation and genomic coadaptation. Here, we review the literature on fluctuating asymmetry of human populations. The most widely used bilateral traits include skeletal, dental, and faci...

METHODS Thirty-six VLBW infants who underwent F-18 fluorodeoxyglucose (F-18 FDG) brain PET and MRI were prospectively enrolled, while infants with evidence of parenchymal brain injury on MRI were excluded. The regional glucose metabolic ratio and asymmetry index were calculated. The asymmetry index more than 10% (right > left asymmetry) or less than -10% (left > right asymmetry) were defined as...

We describe a Libyan boy with an unusual phenotype of multiple congenital anomalies, including triophthalmia, dolichocephaly, porencephaly, cleft lip/palate, facial asymmetry, micrognathia, and VSD. The reported phenotype is likely to represent a new entity of non-chromosomal syndromic triophthalmia. Other possibilities are discussed.

T his study examines how oil price shocks interact with the stock market index within a nonlinear autoregressive distributed lag model in Iran. Based on quarterly data for the period from 1991 to 2017, the findings revealed statistically significant evidence of short-run and long-run asymmetric behavior of stock market index in response to the positive a...
