Vitamin A Affects Flatfish Development in a Thyroid Hormone Signaling and Metamorphic Stage Dependent Manner
Vitamin A (VA) and retinoid derivatives are known morphogens controlling vertebrate development. Despite the research effort conducted during the last decade, the precise mechanism of how VA induces post-natal bone changes, and particularly those operating through crosstalk with the thyroid hormones (THs) remain to be fully understood. Since effects and mechanisms seem to be dose and time-dependent, flatfish are an interesting study model as they undergo a characteristic process of ...

The pleiotropic role of vitamin A in regulating mucosal immunity
The effect of vitamin A on mucosal immunity has never been subjected to extensive studies until recently. We started to work in this area in
the early 1970s when we observed that children with protein-calorie malnutrition (PCM) often had defective mucosal immunity, judging from
the incidence of respiratory tract infections and diarrhea. We reported that these children had depressed secretory IgA (sIgA) levels in their
nasal wash fluids. The IgA level in specimens collected from those superimposed with some degrees ...

Serum vitamin A status is associated with obesity and the metabolic syndrome among school-age children in
Chongqing, China
The aim of our study was to examine the association of vitamin A status with obesity and the metabolic syndrome
(MS) in school-age children in Chongqing, China. A cross-sectional study was conducted of 1,928 children aged
7~11 years from 5 schools in Chongqing, China. Body height, weight, waist circumference (WC) and blood pressure
were measured. Blood glucose, lipids and vitamin A were determined. Overall prevalences for overweight,
obesity and MS were 10.1%, 6.7% ...
