During the initiation stage of pancreatic adenocarcinoma induced by oncogenic Kras, pancreatic cells are exposed to both a protumoral effect and an opposing tumor suppressive process known as oncogene-induced senescence. Pancreatitis disrupts this balance in favor of the transforming effect of oncogenes by lowering the tumor suppressive threshold of oncogene-induced senescence through expressio...

Thirty-six patients with aplastic anemia and three with aplastic anemia-PNH syndrome in eight institutes were studied for the presence of peripheral blood mononuclear cells having a suppressive effect on granulocyte-macrophage (G-M) and erythroid colony formation using a uniform protocol. In 11 cases of 29 (38%) and 9 cases of 29 (31%), the presence of mononuclear cells with a suppressive effec...

The murine suppressive factor of allergy (SFA) has been purified from a T-cell hybridoma and found to consist of two functionally and biochemically distinct protein molecules. One protein (17 kDa) modulates the low-affinity Fc receptor for IgE on lymphocytes (i.e., CD23); it decreases the binding avidity of IgE to CD23-bearing B cells without affecting quantitative expression of CD23 and is thu...

background: suppressive therapy with levothyroxine for reducing the size of thyroid nodules has not been really accepted. the purpose of this study was to assess the effect of levothyroxine on the size of benign thyroid nodules. methods: forty patients with confirmed benign nodule were randomly divided into two groups. group i received 50?g/day levothyroxin for six months but group ii did not t...

The immunologic response of neonatal and of older rabbits to the tissue (transplantation) antigens of pooled rabbit leucocytes was studied, the test system being the suppression of formation of agglutinin to Shigella paradysenteriae by transferred lymph node cells which had been incubated with Shigella antigen. In the active induction of the suppressive effect on the transferred cells it was fo...

The effect of fluvoxamine, a selective serotonin (5-HT) reuptake inhibitor, was studied in a model of anxiety and/or obsessive compulsive disorder (OCD) in mice. In the anxiety/OCD model, marble-burying behavior, marble-burying was significantly suppressed by fluvoxamine at 30 and 60 mg/kg, p.o. and the monoamine reuptake inhibitor clomipramine, at 60 mg/kg, p.o. No suppressive effect, however,...
