AFFECTIONS of the nervous system which result from inadequate nutrition have assumed an increasingly important position through the rapid accumulation of clinical, experimental, and pathological data. The artificial synthesis of a number of the components of the vitamin B complex has made available pure crystalline material in large amounts for clinical research, and thus a milestone in the history of these affections has been passed. It now seems appropriate to review and summarize the knowledge of these important substances. To evaluate the status of a nutritional deficiency in man is difficult. As a rule the patient induces his own disease and provides a deficiency that is not quantitatively measurable, but frequently clinical and laboratory evaluations are attempted. Both the laboratory method and the clinical method have certain advantages. Mice are not yet men and until they are the work coming -from the study of human beings is essential. Since the experience of investigators working with animals may often point the way for clinical research, we have interspersed in this review a few of the pertinent studies on the effect of nutritional deficiency on the nervous system of animals. A scheme for illustrating the multiple factors of the vitamin B complex is given in Fig. 1. To date the following portions of the vitamin B complex have been isolated and synthesized in amounts sufficient to allow for clinical trial: thiamin hydrochloride, nicotinic acid, riboflavin, and 2-methyl, 3-hydroxy, 4, 5-di (hydroxymethyl) pyridine. The deficiencies of these substances as they apply to the nervous system of man will be discussed briefly.read more

TL;DR: A 15-item neurologic examination stroke scale for use in acute stroke therapy trials was designed and interrater reliability for the scale was found to be high, and test-retest reliability was also high, suggesting acceptable examination and scale validity.

TL;DR: The ability of circulating tumor DNA (ctDNA) to detect tumors in 640 patients with various cancer types was evaluated and suggested that ctDNA is a broadly applicable, sensitive, and specific biomarker that can be used for a variety of clinical and research purposes.

Insights into the regulation of protein abundance from proteomic and transcriptomic analyses
TL;DR: Current understanding of the major factors regulating protein expression is summarized to demonstrate a substantial role for regulatory processes occurring after mRNA is made in controlling steady-state protein abundances.

Dopamine, learning and motivation
TL;DR: Dopamine release in the nucleus accumbens has been linked to the efficacy of these unconditioned rewards, but dopamine release in a broader range of structures is implicated in the 'stamping-in' of memory that attaches motivational importance to otherwise neutral environmental stimuli.

Recent studies of the morphology of the neurone in health and disease.
TL;DR: The end of the life-work of Nissl and Cajal forms a convenient starting-point for a survey of recent studies on the morphology of the neurone and it will be convenient first to examine the normal structure of the neuron as indicated by these researches, and secondly to review additions to knowledge of the changes which the neur one undergoes in disease.
