Abstract Purpose To evaluate the relative positions of modern soft contact lenses (SCLs) to limbus/cornea and pupil. Methods Sixty images anterior eyes 101 subjects were acquired over 10 s while participants fixated centre camera lens located 33 cm in front eye a well‐lit (300 lux) clinic. Custom validated image analysis software was used locate boundaries lenses, pupils corneas (limbus). Horizontal vertical lens, pupil limbus calculated from fitted boundaries. Results The mean (standard...

Background: Government agencies at the state and federal levels have developed screening tools to classify disadvantaged communities, which are cumulatively burdened by social marginalization environmental hazards. Status as a recognized community can determine access public funding protections associated with justice policies. In California, multiple been promulgated agencies. Objectives: To extent differentially designated census block groups disadvantaged. Also, whether there were...

Abstract Objectives To study whether photon-counting computed tomography (PCCT) can improve CT number accuracy, precision and reduce patient size dependence compared to dual-energy (DECT) virtual monoenergetic imaging (VMI) single-energy (SECT). Methods Clinical PCCT, DECT SECT scanners were used image a multi-energy quality assurance phantom tissue-equivalent inserts with/without an outer nested annulus, representing two object sizes (18 33 cm). numbers converted linear attenuation...

We describe the major autopsy findings in two adult sibs of original pedigree Lowry et al [Am J Dis Child 121:496–500, 1971 ]. These results support idea that Coffin-Lowry syndrome is a systemic connective tissue disorder. Visceral neuropathy was also noted as basis extensive intestinal diverticular disease.

1. Injektion von Erbsmehlextrakt bzw. Pferdeserum in Trachea oder Lunge fuhrt beim entsprechend sensibilisierten Meerschweinchen und Kaninchen zur allergischen Pneumonic. 2. Die allergische Pneumonie tritt als interstitielle, lappen- herdformige Entzundung auf. Die wesentlichsten Erscheinungen der sind hochsensibilisierten Tier ausgedehnte Hamorrhagien, reichliche Ansammlung eosinophiler Zellen, fibrinoide Gefaswandverquellung, Emphysem, Atelektasen perivasculare Anhaufung...

Zusammenfassung Mit Hilfe der vertikalen Discelektrophorese in Polyacrylamid-Gel ist es möglich, zwei Enzymbanden sauren Spermaphosphatase nachzuweisen. Eine optimale Trennung ergibt sich bei einer Wasserstoffionenkonzentration von pH 7,5 im Trenn-Gel und 5,5 Sammel-Gel 0,1 M Acetatpuffer. Der Vorteil dieser Methode liegt dem relativ geringen apparativen Aufwand, kurzen Trennzeit, hohen Trennschärfe sowie Möglichkeit, äßerst geringe Substanzmengen aufzutrennen. Summary With the aid of...

Anhand tierexperimenteller Untersuchungen wurde die Strahlenbelastung der Niere nach Applikation von 203Hg-Neohydrin berechnet. Histologische ließen schon 8 Tagen bei einer Belastung 14 Rad eine deutliche tubuläre Schädigung erkennen. Diese ist entweder Folge reinen Strahlenwirkung oder Kombinationswirkung Strahlung und Quecksilber (2). Von Verwendung dieser Substanz in Nuklearmedizin abzuraten. Die weiterhin beobachteten Permeabilitätsstörungen am glomerulären Apparat wurden als...
