Thiamine triphosphate synthesis in rat brain occurs in mitochondria and is coupled to the respiratory chain.

In animals, thiamine deficiency leads to specific brain lesions, generally attributed to decreased levels of thiamine diphosphate, an essential cofactor in brain energy metabolism. However, another far less abundant derivative, thiamine triphosphate (ThTP), may also have a neuronal function. Here, we show that in the rat brain, ThTP is essentially present and synthesized in mitochondria. In mit...

Maturation of rat proximal tubule chloride permeability.

We have previously shown that neonate rabbit tubules have a lower chloride permeability but comparable mannitol permeability compared with adult proximal tubules. The surprising finding of lower chloride permeability in neonate proximals compared with adults impacts net chloride transport in this segment, which reabsorbs 60% of the filtered chloride in adults. However, this maturational differe...

Quantitative evaluation of Blood Brain Barrier permeability in transient focal cerebral ischemia in the rat

Introduction: Development of brain edema following focal cerebral ischemia exacerbates primary ischemic injury. Blood brain barrier (BBB) opening is an important part of edema named as vasogenic brain edema. In this study, quantitative alterations of BBB permeability is experimentally evaluated using transient focal cerebral ischemia in the rat. Methods: Two groups of male rats (ischemic and sh...

SYNTHESIS OF 1,8-DIOXO-OCTAHYDROXANTHENES WITH THIAMINE CHLORIDE IN ECO-FRINDLY AND SOLVENT FREE CONDITION

A novel, simple and environmentally friendly method is reported for the preparation of 1,8-dioxo-octahydroxanthene derivatives by the reaction of dimedon with various aromatic aldehydes, using thiamine chloride  as a recyclable catalyst under solvent-free conditions. This procedure has following benefits; simple workup, moderate reaction times, good yields, and completely compatible with enviro...
