Abstract
Triacylglycerol breakdown (lipolysis) results from a series of reactions culminated by activation of "hormone-stimulated" triacylglycerol lipase, an enzyme unique to adipose tissue. We have studied various components of the lipolytic process in human omental adipocyte precursors differentiating in culture. The levels of cyclic AMP, the "second messenger" of lipolytic hormones, were about sixfold higher in fat cell precursors than those in abdominal skin fibroblasts. L-Isoproterenol resulted in significant elevation of cyclic AMP levels in both cell types. Preincubation of intact adipocyte precursors with insulin resulted in significant enhancement of "low Km" cyclic AMP phosphodiesterase activity; in contrast, this hormone had no effect on fibroblast phosphodiesterase activity, a distinctive biochemical difference despite the morphological similarities between the two cell types during the early stages of adipocyte precursor maturation. Incubation of adipocyte precursors with isoproterenol resulted in the release of fatty acids into the medium, findings indicative of "hormone-stimulated" lipase activity and, hence, the operation of the entire "lipolytic cascade"; isoproterenol-stimulated lipolysis was inhibited by insulin. Release of fatty acids from fibroblasts was not observed. Thus, "hormone-stimulated" lipolysis and insulin stimulation of cyclic AMP phosphodiesterase activity are expressed during early stages of human adipocyte precursor differentiation.

Abstract
The properties of the sustained cells in the lateral geniculate nucleus of cat have been studied quantitatively. These cells may be subdivided into two groups, the brightness and the darkness detectors. The former is photoexcitatory neurone and the latter, photoinhibitory. In both types, the rates of sustained discharges are closely related to the levels of retinal illumination over a range about 4 log units. The receptive fields of sustained cells again can be roughly divided into two subtypes according to their size. The large receptive field cells all belong to darkness detectors and are distributed mostly at retinal periphery, which may play some role in signalling the background luminance. The small receptive field cells comprise all brightness detectors and a part of darkness detectors, which are located predominantly around area centralis and may transmit the message of brightness or darkness about picture details and enhance the boundaries of a two-dimensional figure.

Abstract
This paper describes a retarded girl who had a severe seizure disorder and a few minor anomalies, and who was found to have a "G-sized" supernumerary chromosome in all her cells which were examined. Studies of the patient's and her parents' chromosomes by a variety of techniques suggest that the supernumerary chromosome arose following a prezygotic maternal 13;15 translocation.

Abstract
Plasma concentrations of adenosine 3', 5' monophosphate (cyclic AMP), free fatty acids (FFA), glycerol and glucose were measured after 24, 48 and 72 h fasting in healthy male students. There was a marked rise in plasma concentrations of cyclic AMP, FFA and glycerol from 24 to 48 h fasting with no further changes from 48 to 72 h fasting. Plasma glucose concentrations fell. After 72 h fasting, inhibition of adipose tissue lipolysis with a nicotinic acid analogue effected no significant change in plasma cyclic AMP concentrations, indicating that the elevated plasma nucleotide concentrations during fasting were not related to stimulation of lipolysis.

Abstract
10 healthy male volunteers fasted for 72 hours. Their plasma concentration of free fatty acid increased more than two-fold, to 1.8 mmol/l. The number of reversible venous "in vivo" platelet aggregates increased significantly (p less than 0.01); this figure correlated with the concentration of long-chain saturated free fatty acid in plasma (p less than 0.02). The correlation with the amount of long-chain saturated free fatty acid plus oleic acid (18:1) was even better (p less than 0.01). Plasma PF-4 concentration increased, suggesting increased platelet release reaction. In spite of the plasma increase, total platelet FFA concentration was reduced and there was a change in the distribution of platelet free fatty acid which correlated with the degree of aggregation.

Abstract
Four cases of ameloblastic odontomas were found in the Long-Evans rats treated with multiple oral administration of a heavy dose of N-butylnitrosourea. The tumor was found as an expansive enlargement over the mandible and was roentgen-opaque. The tumor was histologically characterized by various elements such as odontogenic epithelium, stellated reticulum tissue, enamel, and/or dentine, and was classified as ameloblastic odontoma.

Abstract
The lunar velocity profile and laboratory data on terrestrial and lunar rocks are constraints on models of lunar history. They show that shock-induced microcracks are absent from the rocks present in the moon today at depths of 25 to 60 kilometers. All possible causes of this observation are examined, and the most likely explanations are that either the rocks at depths of 25 to 60 kilometers formed after the major impacts ceased or the microcracks have annealed at temperatures of about 600 degrees C over geologically long times.

Abstract
The reaction of Paramecium caudatum to solutions containing the ash of cigarette paper was consistent with the response of Paramecium aurelia previously reported. After this confirmation, both these species of Paramecium were used as test organisms during a search for the causative agents for the "Paramecium reaction". A qualitative spectrochemical analysis of cigarette paper ash showed that its chief constituent is calcium (97%) with 12 other detected elements present at levels too low to elicit any response from paramecia. Hydroxyl ions in concentrations equivalent to 0.001 M Ca(OH)2, 0.0008 M KOH, or 0.002 M NaOH simulated but did not duplicate the effect of standard cigarette paper ash solution (as of one cigarette paper in 20 ml water). While neutralization caused the three hydroxide solutions to lose their toxicity, the toxicity of cigarette paper ash solution was not appreciably affected by neutralization. Equivalent solutions of facial tissue, filter paper, and a paper towel, burned the same way as cigarette paper, were used as controls. Each of them affected paramecia differently and none simulated the Paramecium reaction. Further, a comparison between ashes from a paperless cigarette, a whole cigarette, and one with two extra roll-your-own wrappers demonstrated a dependence of the Paramecium reaction on cigarette paper ash as well as a direct correlation between the reaction intensity and the amount of cigarette paper ash present.
