On the pharmacological action of certain organic derivatives of arsenic with special reference to salvarsan and sodium cacodylate

"Approved, Chas. W. Greene."Typescript.Illustrations and graphs pasted in.Tables folded to fit in the text block.Since the introduction of Salvarsan by Ehrlich in the latter part of 1910 many facts have been brought out concerning its reactions in the body. The most important of these pharmacologically are the deaths which have been attributed to its untoward action. The experiments in the present work were undertaken in order to determine whether such action was due to the drug injected or to other conditions accompanying the injection.Includes bibliographical references

Analysis of morbid events and risk factors for death after cardiac transplantation

AbstractRisk factors for death after cardiac transplantation performed at the University of Alabana at Birmingham from January 1981 to July 1985 included (by multivariate analysis) higher calculated preoperative pulmonary vascular resistance (early and constant phases), murphology of cardiomyopathy (versus ischemic heart disease) (constant phase only) and black race (constant phase). overall actuarial survival was 71% at 1 year and 48% at 3 years (including azalhioprine and cyclosporine eras). The hazard function for death was highest immediately after operation and declined rapidly thereafter, merging with a constant phase of risk at about 3 months.The most favorable group for long-term survival was the group of white patients with ischemic heart disease and low pulmonary vascular resistance. When such patients had a pulmonary vascular resistance < 3 units m2, the 3 year survival rate exceeded 85%; The most common causes of death were acute rejection (24%) and infection (17%) The risk of infection remained highest during the first several months after any period of augmented immunosuppression

Susceptibility and immunity to helminth parasites

Parasitic helminth infection remains a global health problem, whilst the ability of worms to manipulate and dampen the host immune system is attracting interest in the fields of allergy and autoimmunity. Much progress has been made in the last two years in determining the cells and cytokines involved in induction of Type 2 immunity, which is generally protective against helminth infection. Innate cells respond to ‘alarmin’ cytokines (IL-25, IL-33, TSLP) by producing IL-4, IL-5 and IL-13, and this sets the stage for a more potent subsequent adaptive Th2 response. CD4+ Th2 cells then drive a suite of type 2 anti-parasite mechanisms, including class-switched antibodies, activated leukocytes and innate defence molecules; the concerted effects of these multiple pathways disable, degrade and dislodge parasites, leading to their destruction or expulsion

Cross-sectional and longitudinal associations between different exercise types and food cravings in free-living healthy young adults

Introduction: An increase in energy intake due to alterations in hedonic appetite sensations may, at least in part, contribute to lower-than-expected weight loss in exercise interventions. The aim of this study was to examine cross-sectional and longitudinal associations between habitual exercise participation and food cravings in free-living young adults. Methods: A total of 417 adults (49% male, 28 ± 4 years) reported frequency and duration of walking, aerobic exercise, resistance exercise and other exercise at baseline and every 3 months over a 12-month period. Food cravings were assessed via the Control of Eating Questionnaire at baseline and 12-month follow-up. Results: Cross-sectional analyses revealed more frequent cravings for chocolate and a greater difficulty to resist food cravings in women compared to men (p < 0.01). Only with resistance exercise significant sex by exercise interaction effects were observed with favorable responses in men but not in women. Significant main effects were shown for walking and aerobic exercise with exercisers reporting more frequent food cravings for chocolate and fruits and greater difficulty to resist eating compared to non-exercisers (p < 0.05). Longitudinal analyses revealed significant interaction effects for other exercise (p < 0.05) with favorable results in men but not women. Furthermore, significant main effects were observed for aerobic exercise, resistance exercise and total exercise with an increase in exercise being associated with a reduced difficulty to resist food cravings (p < 0.05). Discussion: The association between exercise participation and hedonic appetite sensations varies by exercise type and sex. Even though exercise was associated with more frequent and greater difficulty to food cravings in the cross-sectional analyses, which may be attributed to greater energy demands, longitudinal results indicate beneficial effects of increased exercise on appetite control, particularly in men
