Making bread with sourdough improves iron bioavailability from reconstituted fortified wheat flour in mice

This study aimed to evaluate the effect of a diet prepared with traditional sourdough (TS) on iron status. Levels of blood hemoglobin (Hb), Hematocrite (Ht), serum ferritin and serum iron as well as excreted iron were determined in three groups of mice fed with: TS bread (TS group), baking yeast bread (BY group) or bread with no starters (control group), respectively. The results show that the levels of Hb, Ht, ferritin and iron were significantly higher in the TS compared to the BY and control groups. Also a significant decrease in the excreted iron levels was observed in the mice fed with TS compared to the others dietary groups.

In conclusion, the study results indicate an improvement of iron status indicators in mice when they were fed sourdough bread as compared to baking yeast bread and bread with no starters.     

Modulation of lipoprotein lipase activity in the rat by the beta 2-adrenergic agonist clenbuterol.

This study evaluated the effects of beta 2-adrenoceptor stimulation on some determinants of triglyceride metabolism. Male Sprague-Dawley rats were injected twice daily with clenbuterol (30 micrograms.kg-1) for 7 days, or with an equivalent volume of vehicle. Serum triglycerides, hepatic triglyceride secretion rate, and lipoprotein lipase activity in white and brown adipose tissues as well as in red vastus lateralis muscle and heart were evaluated in the fasting state and following a fat-free, high-sucrose meal, 3 h after the last agonist injection. In rats killed in the fasting and postprandial states, clenbuterol reduced the mass of white adipose tissue (-25 and -12%, respectively; p < 0.02), whereas it increased the mass of vastus lateralis muscle (+11 and +7%; p < 0.002) and heart (+13 and %; p < 0.0001). In vehicle-injected animals, the fasting state was associated with lower lipoprotein lipase activity in white and brown adipose tissues, and higher enzyme activity in vastus lateralis and heart, compared with the postprandial state. Postprandially, treatment with clenbuterol reduced lipoprotein lipase activity in white adipose (-24%), whereas it increased enzyme activity in brown adipose (+107%) as well as in vastus lateralis (+35%). In fasted animals, no significant variation of enzyme activity in these tissues was observed following clenbuterol treatment, whereas in the heart, a decrease of lipoprotein lipase activity was observed (-22%). Clenbuterol lowered serum triglycerides significantly (-23%), but not their rate of secretion, whereas the agonist decreased the insulin to glucagon ratio only in the postprandial state.(ABSTRACT TRUNCATED AT 250 WORDS)     

Midbrain hematoma presenting with isolated bilateral palsy of the third cranial nerve in a Moroccan man: a case report

ABSTRACT: INTRODUCTION: Bilateral third nerve palsy secondary to a hemorrhagic stroke is exceptional. To the best ofour knowledge, no similar case has been reported in the literature. CASE PRESENTATION: We describe the case of a 69-year-old Moroccan man who presented with isolated suddenbilateral third nerve palsy. Computed tomography (CT) of the brain revealed a midbrainhematoma. The oculomotor function gradually and completely improved over eight monthsof follow-up. CONCLUSION: Stroke should be included in the differential diagnosis of sudden isolated oculomotorparalysis even when it is bilateral because of the severity of the underlying disease and theimportance of its therapeutic implications.
