abstract basement membrane of glomerular mesangium (bmg) is a thin membrane which helps to support the capillary loops in a renal glomerulus and type iv collagen is require for complete bm formation during glomerulogenesis. in this investigation specific antibody of type iv collagen has been used in light microscopy to study development of bmg of the embryonic and postnatal mouse glomerular mes...

new diorganotin(iv) complexes of the type ph2snl2, bu2snl2 and me2snl2 of the ligands 2-thioacetic-5-phenyl-1,3,4-oxadiazole (hl1) and benzamidophenylalanine (hl2). have been synthesized and characterized by physico-chemical techniques such as (elemental analysis, and electrolytic conductance) and spectral uv-visible, ir and 1h, 13c and 119sn nmr). monomer structures for the complexes, bidentat...

An ambiguity in the calculation of CKM matrix elements from semi-leptonic decay rates is resolved: to every choice of scales for the quark masses in the phasespace factor and in the QCD-correction factor, there corresponds a specific QCDcorrection factor. This factor is modified in such a way as to make the final result independent of the scales. Specific expressions are given for the case of o...

Doppler ultrasound without concomitant echocardiographic imaging was used to grade isolated aortic regurgitation in 21 patients. The severity of aortic regurgitation was subsequently graded (from 0 to IV) angiographically. A 2 MHz continuous wave Doppler transducer was placed over the apex of the heart and the beam was aimed parallel to the mitral flow by means of acoustic guidance. Mitral pres...

The rehabilitation of a patient in the Kennedy class IV situation demands biomechanical balance and aesthetic improvement. The long-span condition complicates the problem because of the unavailability of sufficient number of abutments to support the prosthesis. Conventional removable prosthesis and fixed partial denture are not advised for the same reason. This report describes a novel techniqu...

This population-based study reports on the prevalence and characteristics of specific phobia (SP) and phobic fears in an elderly population. A representative population sample of Swedish 70-year-olds without dementia (N = 558) was examined using semi-structured interviews. Phobic fears included fear of animals, natural environment, specific situations, blood-injection-injury and 'other'. Mental...
