Thin-walled roots restored using conventional cast metal post-cores are at risk of fracture. Placing a thick intermediate layer of resin-based composite (RBC), sandwiched between the root dentine and a small-diameter metal post or dowel, may improve the fracture resistance of such roots. In this initial laboratory study, two similar groups each of six decoronated maxillary central incisor teeth...

The superficial squamous cells of rat transitional epithelium are limited, on their luminal face, by an asymmetrically thickened membrane. Patches of similar thick membrane are found in the walls of the Golgi cisternae and it is suggested that the Golgi system is the site of assembly of the thick plasma membrane. This implies membrane flow from the Golgi apparatus to the cell surface, and there...

SUMMARY Quantification of ventricular wall stress is necessary for an understanding of both normal and pathological ventricular mechanics. At present there are no reliable means to measure, directly, wall stresses in the intact ventricle. Thus, we must rely on mathematical models to predict these stresses, knowing that the predictions cannot be validated directly. Since each model employs certa...

We predicted the shape of the end-systolic pressure-thickness relationship (ESPTR) by modeling the left ventricle as thick-walled sphere. To test the validity of the predicted relationships, we then measured the ESPTR over wide volume ranges in seven isolated blood-perfused canine hearts. Both simulation and experiments demonstrated that the ESPTR is curvilinear. However, within a physiological...

A 55-year-old lady reported to the surgical OPD with clinical findings of acute peritonitis. Emergency laparotomy was performed. The peritoneal cavity was full of purulent material, however, the gut was normal. An 8 x 6 cm thick walled cyst was found in the left ovary with a minute perforation and purulent fluid coming out of it. Thorough peritoneal lavage along with left oophorectomy was perfo...

Nilgirianthus heyneanus is widely used in South India in place of Sahachara (Barleria prionitis L) and is considered as an important Vatahara drug. Detailed pharmacognosy of the root of N. heyneanus commonly known as Karim Kurinji (Malayalam) in Kerala has been carried out. Some of the diagnostic features of the drug are pigmented cystoliths in the cortex and pith region; yellow colour cell con...

Generally benign, renal angiomyolipomas are neoplasms composed of mature adipose tissue, smooth muscle, and thick-walled blood vessels. Although asymptomatic, massive retroperitoneal hemorrhage from angiomyolipomas accompanied by hypovolemic shock has been found in up to 10% of patients, usually those with large tumors. We report the case of a 33-year-old woman with spontaneous rupture of an an...

HIstology: Section from the lesion shows a large focus of caseous necrosis rimmed by epithelioid cells, lymphocytes, macrophages and Langhan’s giant cells and a dense collagenous wall. Within the caseous necrosis, ghost outlines of necrosed blood vessels are seen surrounded by an eosinophilic, fibrinous material which represents tuberculous immune complex deposition. A thin compressed collar of...

A 29-year-old man presented with dull abdominal pain and a lump occupying almost the entire abdomen, four months after a fall from a height. Ultrasonography revealed a cystic lesion with debris occupying almost the entire abdomen. Diagnostic tap revealed brownish fluid. Exploration revealed a huge thick-walled cyst of the sigmoid mesocolon, which could be enucleated out entirely. Histology sugg...
