Corneal surface changes in keratoconjunctivitis sicca. Part II: the mucus component. A non-contact photomicrographic in vivo study in the human cornea

Purpose Description of mucus on the corneal surface and in the precorneal tear film in keratoconjunctivitis sicca (KCS). Methods In all, 24 patients with KCS examined with slit lamp and by non-contact photomicrography. Results Material interpreted as mucus seemed to exist in three varieties: one optically dense, light reflecting, and with definite forms ( fine threads, variously thick and long str

Geometric foundation and quantification of the flow in a verbal expression

This article shows that language must be conceived of as a natural system that becomes structured through rhythmic driving forces. This gives weight to the hypothesis that rotatio¬nal dynamics is basic to the effects that selective textual movement patterns have on the evolution of texture, i.e. a text surface. The experimental procedure has been focused on the manipulation of text translation, as

Nomenclature of the veins of the lower limb: Extensions, refinements, and clinical application

The relative deficiency of the official Terminologia Anatomica with regard to the veins of the lower limbs was responsible for a nonuniform anatomic nomenclature in the clinical literature. In 2001, an International Interdisciplinary Committee updated and refined the official Terminologia Anatomica regarding the veins of the lower limbs. Recommendations for terminology were included in an updating

Simulation of grafted polymers on nanopatterned surfaces

Structural properties of polymer brushes on nanopatterned surfaces in good solvent have been determined by computer simulations. Scaling relations for the brush height and brush width are proposed. The properties of the central part of the patterned brush remain constant as long as the pattern is wider than a few times the brush height. The results agree qualitatively with recent AFM experiments,

Biocompatibility of nitinol and stainless steel in the bladder: An experimental study

Purpose: We tested the biocompatibility of nitinol, a nickel titanium alloy, and stainless steel (SS) as bladder implant materials. Materials and Methods: Rats received a nitinol implant, an SS implant or were sham controls. Two, 3, 6 and 8 weeks following implantation 24-hour voiding behavior studies were per-formed to investigate bladder irritation. All animals were sacrificed 8 weeks after impl

Distribution of different fibre types in human skeletal muscles. I. Method for the preparation and analysis of cross-sections of whole tibialis anterior

The aim of this study was to examine whether small biopsy specimens are representative of the whole human skeletal muscle or whether the different fibre types are unevenly distributed at different depths of the muscle. Ten micrometre thick cross-sections of whole human tibialis anterior were prepared using LKB PMV Cryo-Microtomes with a stroke length of 160 to 480 mm and the sections were stained

Polymorphism in the MHC2TA gene is associated with features of the metabolic syndrome and cardiovascular mortality.

BACKGROUND: Recently, a -168A-->G polymorphism in the MHC class II transactivator gene (MHC2TA) was shown to be associated with increased susceptibility to myocardial infarction (MI). AIM: To confirm the association between the MHC2TA -168A-->G polymorphism and MI and to study its putative role for microalbuminuria, the metabolic syndrome (MetS) and cardiovascular mortality. MATERIALS AND METHODS:

Adaptation of postural control to perturbations-a process that initiates long-term motor memory.

The objective was to investigate postural control adaptation during daily repeated posturography with vibratory calf stimulation. The posturography was performed with eyes open and closed daily for 5 days and after 90 days on 12 healthy subjects. The postural control adaptation could be described as two separate processes, a rapid adaptation during the test progress and a long-term habituation bet

Lipolytic activity of Staphylococcus aureus strains from disseminated and localized infections

Lipase production of 425 S. aureus strains isolated from patients with different clinical diagnoses and healthy carriers were measured by a specific method, using emulsified trioleoylglycerol substrate. Strains isolated from patients with septicemia showed significantly higher lipase activity than osteomyelitis strains (p = 0.011), impetigo strains (p = 0.002) and strains isolated from healthy rel

Ferrimagnetic 4f spin order in O/Gd surface monoxide

The remanent 4f spin structure of the epitaxial surface monoxide O(1 X 1)/Gd(0001) has been investigated using magnetic dichroism in core-level photoemission (MDPE). Here we report the observation of a substantial dichroic signal of the chemically shifted Gd-4f PE line. It demonstrates the presence of a non-vanishing net magnetization of the surface monoxide layer at cryogenic temperatures. (C) 20

Prognostic importance of new small Q waves following non-ST-elevation acute coronary syndromes

PURPOSE: to investigate the prognostic importance of new small Q waves following an acute coronary syndrome. METHODS: We assessed 6-month mortality in 10,501 patients with non-ST-elevation acute coronary syndromes who had survived 30 days and had both admission and 30-day electrocardiograms. Patients were stratified by whether they had no new Q waves (n = 9447), new 30- to 40-ms Q waves (n = 733),
