Search for Surrogate Marker(s) of Immunity Following Vaccination with Experimental Vaccine (Autoclaved Leishmania Major + Bacille Calmette-Guérin) in Human Volunteers

Description: Cutaneous leishmaniasis (CL) is usually a self-limiting lesion on the skin while visceral leishmaniasis is a progressive, systemic disease with high mortality even if treated. The problem associated with treatment and vector control justifies a search for an effective vaccine which seems to be the only practical means to control the disease. The aim of this study is to identify immunological surrogate marker(s) associated with protection against Leishmania infection. The results indicate that a… more

Comparisons of Self-Perceptions in Boys With Attention-Deficit Hyperactivity Disorder, Learning Disabilities, and Non-Referred Boys

Description: A limited amount of research exists that addresses low self-esteem, poor self-concept, and distorted self-image in children with Attention-deficit Hyperactivity Disorder (ADHD). The most urgent task is to test assumptions regarding self-perception and to assess the dimensions of self-concept influenced by this disorder. The Self-Perception Profile for Children (Harter, 1985) was used in the present study to assess those dimensions. Participants included 34 boys with ADHD, 27 boys with LD, and 3… more

Intracellular Location of Carotenoid Pigments in Yeast-Phase Cells of Wangiella Dermatitidis and Cell Wall Morphology After Enzyme Treatment

Description: Carotenoid pigments in W. dermatitidis, the first pathogenic, dematiaceous fungus in which carotenoid pigments nave been reported, are located primarily (81%) in lipid organelles which floated on the surface of the supernatant fraction of lysed cells. Pigment in this fraction could be extracted with ethyl ether without prior treatment with acetone indicating the pigment is unbound in the lipid organelle. Eight percent remains after exhaustive ether extraction and is recovered after the sample i… more

How Do Enzymes Wear Out? Effects of Posttranslational Modifications on Structure and Stability of Proteins; The Triosephosphate Isomerase Model

Description: Triosephosphate isomerase (EC 5.3.1.1., TPI) undergoes specific posttranslational modifications (deamidation and oxidation) which are believed to initiate protein turnover by destabilization of the dimer. The crystal structures, amino acid sequences, and aging related changes of TPI from various species have been independently characterized by several laboratories. TPI has thus become the prototype enzyme for examining the initial steps in protein turnover. The binding of substrate enhances the… more
