Endothelin is a potent vasoconstrictor, whereas endothelium-derived relaxing factor (EDRF) is a potent vasodilator. Both are produced by the endothelium. Although they have been studied extensively in large vessels, little is known about their actions in renal microvessels. Using microdissected rabbit afferent arterioles, we studied the vascular response to synthetic endothelin and its interact...

Background: Basal cell carcinoma (BCC), the most common form of skin cancer, usually occurs in the sun-exposed areas of the body like head and neck, yet is also seen in unexpected sites. Myriad studies have mentioned a lower limb BCC incidence rate of 1.5-13.5%.Methods: The present retrospective cross-sectional study was conducted on 650 BCC patients, who were referred to the dermatology tumor ...

PURPOSE To compare the measurement of the basal diameter of choroidal melanoma, an important parameter for planning treatment and as a prognostic factor, by standardized ophthalmic ultrasound versus that obtained using a wide-angle fundus camera. METHODS The longest and shortest basal diameters of 104 consecutive choroidal melanomas of patients seen at the ocular oncology service of the Hadas...

Tree height, basal diameter, and survival were examined in thirteen-year-old provenance test established by 30 seed sources of Scots pine (Pinus sylvestris L.) at two exotic sites of the species in Southern part of Turkey. Variations within provenance and among provenances and relations among the traits were estimated to compare Scots pine provenance and two other native species. Averages of tr...

OBJECTIVES We set out to determine if intraoperative pre-bypass transoesophageal echocardiography could assist in predicting which patients are at greatest risk for systolic anterior motion (SAM) after mitral valve repair (MVR). METHODS Three hundred and seventy-five consecutive patients who underwent reconstructive MVR surgery for degenerative disease were included. Data were collected using...

Three large-scale, experimental, dispersed residual tree sites established in coastal British Columbia, Canada were measured for planted Douglas-fir tree growth and survival five to six years after planting. The dispersed trees were predominantly large diameter (60 cm+) Douglas-fir left with a range of 0% to 30% of the original forest stand basal area (0 m ha to 14 m ha). Two sites had 0%, 5% a...

Basal cell carcinoma is the most commonly seen nonmelanoma skin cancer which is rarely encountered in the childhood period. An 11-year old child was admitted to our clinic due to an erythematous and a slightly pigmented lesion with a 3 × 4 cm diameter on his posterior scalp. Macroscopically, the lesion was excised with a 10 mm safety margin. Pathologic examination revealed a basal cell carcinom...
