Linomide (LS-2616, quinoline-3-carboxamide) is a synthetic immunomodulator that stimulates natural killer cell activity and activates several lymphocytic subpopulations in experimental animals and humans. In this study we determined the effect of oral treatment with linomide on the development of ex …

Restimulation of autoreactivity in two different BB rat sublines of the same origin (Ottawa, Canada) was investigated by syngeneic islet transplantation into diabetic animals. Despite identical methods and conditions recurrence of hyperglycaemia was observed in BB/OK rats (Karlsburg, Germany) but no …

The prevention of insulin-dependent diabetes (IDD) in humans remains an elusive goal, despite the broad spectrum of therapeutic interventions that prevent the development of IDD in the non-obese diabetic (NOD) mouse. Can an animal model in which spontaneous autoimmune pathology is interrupted so eas …

The effects of the novel immunosuppressant Deoxyspergualin (DSP) on the development of experimental autoimmune thyroiditis (EAT) in CBA mice were studied. For EAT induction, the mice were immunized with 100 micrograms of porcine thyroglobulin (p Tg) emulsified in CFA on day 0 and in IFA, for boostin …

Nicotinamide can protect the NOD mouse from diabetes if given early enough and in sufficient dose. The effect partly wanes with time. There is reduced islet inflammation. Similar protective effects can be demonstrated in quasi-experimental interventions in humans--both diabetes related and unrelated …

Experimental SLE can be induced in mice by immunization with a human mAb to DNA (16/6Id). Immunized mice develop Abs to the 16/6Id immunogen, DNA, and nuclear Ags. Subsequently, clinical manifestations of disease develop, including leukopenia, proteinuria, and immune complex deposits in the kidney. …

We describe the induction and prevention of autoimmune insulin dependent diabetes mellitus (IDDM), and its pathological substrate, insulitis, in congenitally athymic nude rats following injections of major histocompatibility complex (MHC) compatible lymph node T cells. The cells capable of adoptive …

(C57BL/6 x DBA/2)F1 (B6D2F1) mice inoculated with parental DBA/2 (D2) splenocytes develop chronic stimulatory graft-versus-host reaction with many of the clinical manifestations of systemic lupus erythematosus. This investigation tested the ability of 8-methoxypsoralen (8-MOP) and ultraviolet A (UVA …

To understand the role of CD8+ T cells in experimental autoimmune myasthenia gravis (EAMG), CD8+ T cells were depleted by injecting a monoclonal anti-rat CD8 antibody (OX8) into Lewis rats immunized with Torpedo acetylcholine receptor (AChR) in complete Freund's adjuvant (CFA). CD8-depleted EAMG rat …

Individuals at high risk of developing insulin-dependent diabetes mellitus can now be identified by immunologic testing. This ability to predict future cases of IDDM raises the possibility of intervention to prevent the disease. An intervention study in New Zealand using nicotinamide treatment showe …

Glutamic acid decarboxylase (GAD) is the enzyme responsible for the synthesis of gamma-aminobutyric acid (GABA). GAD has been identified as a 64-kDa antigen expressed in pancreatic beta-cells, to which autoantibodies are generated prior to the onset of type 1 (insulin-dependent) diabetes mellitus. G …

This chapter aims to describe ways in which autoimmunity can be prevented or reversed and 'self-tolerance' re-established. To this end we have largely restricted our overview to the two main autoimmune disease models with which we are involved, i.e. IDDM in NOD mice and EAT in H-2k mice although, wh …

Whether achieving normoglycemia is beneficial or dangerous to the diabetic patient has been a matter of debate. The authors explore such issues as the prevention or reversal of complications with tight metabolic control, and the methods currently available to achieve normoglycemia.

Two studies have suggested that the risk of rheumatoid arthritis in women using oral contraceptives is less than half that of nonusers. When a third study from the Mayo Clinic failed to confirm these findings, it was criticized for inclusion of ineligible subjects, misclassification of oral contrace …

Studies of energy conservation efforts to reduce CO2 emissions in the residential sector are abundant; however similar efforts in organizations have not received as much attention as they deserve. In this study, we focus on methods for increasing employees' readiness to change their behav …

Radiation-induced optic neuropathy (RION) is a rare side effect following radiation therapy involving the optic structures whose onset is, due to the low amount of available data, challenging to predict. We have analyzed a multi-institutional cohort including 289 skull-base cancer patients treated w …

COVID-19 has brought a massive psychological impact on individuals' life. The current study sets a significant purpose to test the model whether post-traumatic stress and coping strategies affect stress-related growth regarding the COVID-19 event. One hundred and ninety-nine participants have partic …

In the late '90, Dr. Indira Raman, at the time a postdoctoral fellow with Dr. Bruce Bean, at Harvard University, identified a new type of sodium current, flowing through the channels that reopens when the membrane is repolarized. This current, called "resurgent Sodium current," was originally identi …
