Research in modern investigative ophthalmology and vision science has two fundamental uses for human tissues: laboratory studies of anatomy, physiology, biochemistry, pathology, genomics, and proteomics, and ophthalmic device research and development. Because population aging focuses attention on chronic diseases such as age-related maculopathy (ARM), glaucoma, and diabetic retinopathy, it is i...

background: thermoluminescence dosimetry is one of the dosimetry procedures used widely as routine and personal dosimeters. in order to extend this kind of dosimeters, dental tissue has been examined and was found promising as a tld dosimeter. materials and methods : in this study, 70 health teeth were collected. the only criterion, which was considered for selection of the teeth, was the healt...

introduction:blood-borne infectious agents are one of the main anxieties of blood transfusion organization in all countries. according to who, the blood healthy and blood safety is included ensuring and monitoring of quality and efficiency for all patients requiring blood transfusion. we at the current study intend that survey prevalence hiv ab, hcv ab, hbs ag among blood donors refer to the bl...

PURPOSE To investigate the expression of the muscarinic receptor (mAChR) subtypes (m1, m2, m3, m4, and m5) in the human ciliary muscle. METHODS cDNA probes specific for the m1 to m5 subtypes were used to characterize the expression of subtype-specific mRNAs by in situ hybridization and Northern blot analysis on a cell line derived from human ciliary muscle tissue (H7CM), sectioned tissue from...

BACKGROUND Diabetic foot ulceration has a complex and multifactorial etiology and can involve changes in the pathophysiology of the plantar soft tissue. In the current study, histomorphological analyses of diabetic and non-diabetic plantar tissue were performed. It was hypothesized that the diabetic tissue would have thicker skin (epidermis and dermis), less interdigitation between the dermis a...

Using a popliteal lymph node weight assay the graft-versus-host activity of lymphocytes from donors immunized with allogeneic tissue has been assayed by comparison with that of lymphocytes from nonimmune donors. When the donors were immunized against weak histocompatibility antigens (non-AgB) the specific GVH activity of its lymphocytes was increased. This increase was greater if spleen cells r...

INTRODUCTION Human heart valves are used as replacement valves and have satisfactory functional results compared with conventional prostheses. OBJECTIVE Characterize the profile of effective heart donors from the human valve bank of the santa casa de misericórdia de curitiba and analyze the association between the profile variables. METHODS It consists of a retrospective and quantitative st...

The clinical significance of ABO and Rhesus blood group systems has been well documented. The objective of this study was to determine the frequency of ABO and Rhesus blood groups in blood donors in Lahore, Pakistan, with a view to generate data with multipurpose future practicalities in the field of medicine. Blood groups of 3000 blood donors were determined by commercially available standard ...
