introduction: the aim of the present study was to compare the efficacy of 2% lidocaine to 4% articaine in buccal infiltration of maxillary first molars with irreversible pulpitis. moreover, the effect of root length on success of anesthesia irrespective of the type of anesthetic agent was assessed. methods and materials: fifty patients suffering from painful maxillary first molars with irrevers...

Abstract Aim CT imaging is increasingly used in the pre-operative localisation of abnormal parathyroid glands. Parathyroid glands typically enhance arterial phase and washout delayed phase. The aim this novel study was to analyse classify all various enhancement patterns. Method 42 patients underwent a three-phase which identified 45 subsequently had surgical excision histological assessment. H...

The ability of four steroids and three bile acids to promote the appearance of hyperplastic foci and hyperplastic nodules initiated by diethylnitrosamine (DEN) in the liver of male Fischer rats was tested and compared with that of the known promoter phenobarbital (PB, 0.05%) as a standard value. Two weeks after a single dose of 200 mg of DEN per kg, the animals were exposed to test chemicals fo...

Facial asymmetry is relatively common, but it becomes a disease when condylar hyperplasia is involved. The purpose of this investigation was to describe and compare the morphological characteristics of hyperplastic condyles to their nonhyperplastic contralateral side. Fifteen subjects aged between 14 and 29 years with facial asymmetry and diagnosed with unilateral condylar hyperplasia were stud...

Studies in both humans and rodents have found that insulin(+) cells appear within or near ducts of the adult pancreas, particularly following damage or disease, suggesting that these insulin(+) cells arise de novo from ductal epithelium. We have found that insulin(+) cells are continuous with duct cells in the epithelium that makes up the hyperplastic ducts of both chronic pancreatitis and panc...

The preservation of deciduous teeth is crucial in pediatric dentistry to maintain normal speech, development, and self-esteem, while also preventing secondary issues like space loss tooth impaction. Different materials approaches have been explored over time, ranging from mummification maintaining pulp vitality promoting healing. In today's conservative dentistry, techniques indirect treatment ...

The ability of four steroids and three bile acids to promote the appearance of hyperplastic foci and hyperplastic nodules initiated by diethylnitrosamine (DEN) in the liver of male Fischer rats was tested and compared with that of the known promoter phénobarbital (PB, 0.05%) as a standard value. Two weeks after a single dose of 200 mg of DEN per kg, the animals were exposed to test chemicals f...

We describe a case of a hyperplastic anterior choroidal artery (AChA) with double persistent anastomotic channels. This hyperplastic AChA, which was detected at vertebral angiography, is different from previously reported cases, because it has an unusual, secondary anastomotic channel.

The expression of receptor for androgen (AR), oestrogen alpha and beta (ERalpha and ERbeta) and progesterone (PR) was examined immunohistochemically in canine prostate specimens (normal, hyperplastic, inflamed [prostatitis] or neoplastic). AR immunolabelling was seen in 100% of epithelial cells of normal and hyperplastic tissue, the corresponding figures for inflamed and carcinomatous tissue be...
