BACKGROUNDS AND AIMS Shoot demography affects the growth of the tree crown and the number of leaves on a tree. Masting may cause inter-annual and spatial variation in shoot demography of mature trees, which may in turn affect the resource budget of the tree. The aim of this study was to evaluate the effect of masting on the temporal and spatial variations in shoot demography of mature Betula gr...

Ring chromosomes are rare chromosomal disorders that usually appear to occur de novo. A ring chromosome forms when due to deletion both ends of chromosome fuse with each other. Depending on the amount of chromosomal deletion, the clinical manifestations may be different. So, ring 18 syndrome is characterized by severe mental growth retardation as well as microcephaly, brain and ocular malformat...

The facilities and services of the GEOmetry LABoratory (GEOLAB) at the NASA Langley Research Center are described. Included in this description are the laboratory functions, the surface modeling and grid generation technologies used in the laboratory, and examples of the tasks performed in the laboratory.

The clinical and laboratory details of 10 patients with predominantly immunological problems were circulated to selected physicians in different forms of hospital practice. In general, these physicians would prefer to select their own immunological tasks and could get these performed in their clinical pathology laboratories or regional immunology centres. Immunologists are seen predominantly as...

Background: Systemic sclerosis (SSc) is an autoimmune connective tissue disease characterized by vasculopathy and excessive collagen deposition in the skin and internal organs. Based on the skin damage we divide the patients into two groups: limited and diffuse SSc. In restricted type, the thickness of the skin is limited in the face and distal parts of the elbows and knees, with less involveme...

Background: Cutaneous drug reaction is a common side effect of antiepileptic drugs (AEDs). In recent years, a significant increase in cases of cutaneous drug reaction due to AEDs and some changes in its pattern in our department have been noticed. Therefore, we carried out this study to present clinical and paraclinical characteristics of these cases. Methods: All records of patients who were h...

The proposed rule for the Clinical Laboratory Improvement Amendments of 1988 (CLIA '88) describes uniform standards for the design of proficiency testing (PT) challenges and for the evaluation of laboratory performance. Successful performance on PT is a condition for laboratory certification by the federal Department of Health and Human Services. We conducted a retrospective evaluation of PT da...

introduction : albumin, one of the most important plasma proteins, has a difficult process of synthesis and production. we compared two different methods for albumin purification: carboxymethyl cellulose (cm cellulose) resin exchange and diethylaminoethyl cellulose (deae cellulose) resin exchange in order to determine which resin could be more beneficial. materials and methods : two ion exchang...

PURPOSE To evaluate the Proview Eye Pressure Monitor as a medical instrument and as a technique for enabling a patient to obtain an accurate measure of his or her intraocular pressure (IOP). DESIGN An experimental laboratory evaluation and an independent prospective clinical study to test the reproducibility and accuracy of the Proview technique relative to Goldmann applanation tonometry. P...
