A monoclonal antibody specific for the chicken alpha 1 (XII) collagen chain was used to immunolocalize type XII collagen in the corneoscleral of 17-19-day-old chicken embryos. These immunofluorescence studies localized type XII collagen around the scleral cartilages and ossicles. There was also a striking positive staining in the scleral spur and stroma of the corneolimbus beneath the external ...

A 47-year-old man was admitted to hospital with jaundice and ascites. Cirrhosis was attributed to alcohol abuse as his alcohol intake had been high for at least 10 years. Prior to admission, he had ceased drinking alcohol and had been treated with diuretics and pentoxifylline. Blood tests revealed an elevated plasma bilirubin (11 mg/dL or 187 mmol/l), a mild elevation of alkaline phosphatase (1...

The main problems of indication, operating techniques and results are recalled after 39 cases of pectus excavatum (P.E.) operated on 74 followed up children. Analysis revealed frequent family trend, respiratory past records of Marfan's morphological type and intrathoracic spur. Sternochondroplasty had varied stabilizing ways : first Garnier's technique, then Judet's costal clips, today the medi...

Recent breakthroughs in mobile phone technology are focusing on new techniques that allow the compact integration of dualband printed antennas into handsets with an increase in their inherent narrow bandwidth. In this letter, no el rectangular, circular, triangular, hexagonal, and bow-tie-shaped spur-line dual-band printed structures ha e been designed, measured, and compared. Although a second...

Chronic anemia is common in liver cirrhosis. In this setting, the pathogenesis of anemia is complex and multifactorial. Spur cell anemia is a serious disorder in cirrhotic patients and is associated with poor prognosis. Liver transplantation constitutes the only therapeutic tool. We report a case with severe spur cell anemia in alcoholic liver cirrhosis. In the attempt to investigate the origin...

This paper gives an overview of fractionalN phase-locked loops (PLLs) with practical design perspectives focusing on a ∆Σ modulation technique and a finite-impulse response (FIR) filtering method. Spur generation and nonlinearity issues in the ∆Σ fractional-N PLLs are discussed with simulation and hardware results. High-order ∆Σ modulation with FIR-embedded filtering is considered for low noise...

We show that firms with chief executive officers (CEOs) who gain general managerial skills over their lifetime work experience invest more in R&D and produce more patents. We address the potential endogenous CEO-firm matching bias using firmand CEOfixed effects and variation in the enforceability of non-compete agreements across states and over time during the CEO’s career. Our findings suggest...

Methods: LSSR was conducted employing two different laser systems: a) CO2 laser, articulated arm with nasal hand-piece / wave guide, or b) 980nm diode laser with fiber delivery system. The surgical technique includes direct transmucosal ablation of anterior or posterior cartilaginous spurs without incisions, mucoperichondrial flaps, therefore eliminating the need for post-op packing. The laser ...

Expert systems have experienced tremendous growth and popularity since their commercial introduction in the early 1980’s. Today, expert systems are used in business, science, engineering, manufacturing, medical diagnosing, chemical, and many other fields. Mechanical engineers are the major users, expert systems, are finding rapid application in industry for such tasks as analysis of quality con...
