Genetic Deletion of Galectin-3 Alters the Temporal Evolution of Macrophage Infiltration and Healing Affecting the Cardiac Remodeling and Function after Myocardial Infarction in Mice.

We studied the role of galectin-3 (Gal-3) in the expression of alternative activation markers (M2) on macrophage, cytokines, and fibrosis through the temporal evolution of healing, ventricular remodeling, and function after myocardial infarction (MI). C57BL/6J and Gal-3 knockout mice (Lgals3) were subjected to permanent coronary ligation or sham. We studied i) mortality, ii) macrophage infiltration and expression of markers of alternative activation, iii) cytokine, iv) matrix metalloproteinase-2 activity, v) fibrosis, and vi) cardiac function and remodeling.

Evaluation of oxfendazole, praziquantel and albendazole against cystic echinococcosis: a randomized clinical trial in naturally infected sheep.

Background: Cystic Echinococosis (CE) is a zoonotic disease caused by larval stage Echinococcus granulosus. We determined the effects of high dose of Oxfendazole (OXF), combination Oxfendazole/Praziquantel (PZQ), and combination Albendazole (ABZ)/Praziquantel against CE in sheep.

Methodology/principal Findings: A randomized placebo-controlled trial was carried out on 118 randomly selected ewes.

Immunocytochemistry on suprachiasmatic nucleus slices.

Immunocytochemistry (ICC) is a sensitive and powerful method that is used to localize and identify cells containing a particular antigen. This chapter is dedicated to ICC of suprachiasmatic nucleus (SCN) slices. After a brief introduction to the technique, the materials and methods sections describe two different methods to obtain SCN slices--the first one for fixed tissue, the second one for fresh frozen tissue--followed by the description of two methods of antibody detection: the indirect method and the avidin-biotin complex one.

Spatio-temporal analysis of light-induced Fos expression in the retina of rd mutant mice.

Rd mutant mice are visually blind but they maintain the ability of synchronising their circadian rhythms to the external light-dark cycles. We used immunocytochemical procedures to detect light-induced Fos expression in the rd mice retina. We found that Fos is expressed in the rd retina in an unattenuated pattern through the entire life of the animal.

Fos expression in the retina of rd/rd mice during the light/dark cycle.

An anti-Fos protein antiserum was used to elucidate the diurnal expression of Fos protein in the normal and degenerate rd/rd mice retina. We have found that Fos expression is stimulated in cells of both inner nuclear layer (INL) and ganglion cell layer (GCL) at the onset of light period and reaches its maximum after 2 h. After which, the number of stained nuclei decreases along the light/dark cycle until almost no reaction is observed at the end of dark period.
