1-(2-Hydroxy-4-methoxybenzophenone)-4-phenylthiosemicarbazone (HMBPT) was investigated as a new reagent for the flotation of vanadium(IV). At pH approximately 1.5, vanadium(IV) forms a 1:1 pale-violet complex with HMBPT in aqueous solution. An intense clear violet layer was formed after flotation, by adding an oleic acid (HOL) surfactant. The composition of the float was 1:1 [V(IV)]:[HMBPT]. A ...

The aim of this study was to evaluate the frequency of roots, root canals and apical foramina in human permanent teeth using cone beam computed tomography (CBCT). CBCT images of 1,400 teeth from database previously evaluated were used to determine the frequency of number of roots, root canals and apical foramina. All teeth were evaluated by preview of the planes sagittal, axial, and coronal. Na...

In descriptions of surgical procedures in mandible, often there is no mention of an anatomical variance, the genial spinal foramina, where nerves and vessels go through. Aim of this study is to investigate frequency, shape, and dimensions of these foramina. 56 computed tomography dentascans were analyzed with an implant planning software. The considered parameters were frequency, number, positi...

OBJECTIVE To use CT scanning to evaluate the precision with which acupuncture needles can be inserted into sacral foramina to establish sacral nerve modulation by electroacupuncture. METHODS The subjects were five adult women (mean age 71.6 years). These five cases were divided into two groups. In the first three subjects (group A) the intention was to insert acupuncture needles in the S3 and...

A total of 142 metatarsal bones of unknown age and sex were examined for the length of the bone and number & position of the nutrient foramen. Study also included the direction of nutrient foramina and it’s distances from both the ends . It was observed that almost all the Metatarsals had one nutrient foramen in the middle third of their shaft In 5 th Metatarsals majority of foramina were situa...

BACKGROUND AND PURPOSE Complex and syndromic craniosynostosis can be complicated by raised intracranial pressure (ICP), which in the absence of other identifiable origins, is probably caused by venous hypertension. Children with these conditions have been shown to have narrowing of the sigmoid sinus-jugular vein complex. Evidence of bony narrowing of the jugular foramina in children with comple...

"Enlarged parietal foramina" is a congenital malformation with autosomal dominant inheritance. The condition is usually self-limiting and doesn't require any treatment. However, it may also be associated with encephalocele, vascular anomalies or may be a part of syndrome. We present a case of enlarged parietal foramina in a child and discuss its imaging findings and the associated intracranial ...

Thefts and losses of precious books are not rare. Here we report several incidents concerning vesalius's Fabrica: the fire of the University Library of Leuven in Belgium, the fate of the collection of the Leopoldina Library of Halle in Germany, the thefts from the Crerar Library in Chicago and in Christ Church College in Oxford, the disappearance of an exceptionally beautiful 'royal' copy from ...
