Equine tendon injuries have been recognized and treated for centuries. In early American texts, poor conformation was considered a primary risk factor. “Tied-in” at the knees and long, weak, and slender pasterns were thought to predispose the horse to injury because of mechanical disadvantage. Any trait that favored fetlock extension such as low heels and long toes was thought to increase a hor...

The purpose of this study was to investigate the relationship between glove use and acute traumatic occupational hand injury. We used a case-crossover, within-subject study design to control for differences between individuals such as occupation, injury history, age, gender, risk-taking behavior, manual dexterity, and muscle strength. A total of 1166 hand-injured workers were interviewed regard...

Acute alveolar injury closely resembling that seen in humans was induced in dogs by subcutaneous injection of N-nitroso-N-methylurethane. Necrosis of alveolar epithelial cells was observed during early injury. Proliferation of immature epithelial cells which began during early injury and became massive after peak injury was followed by their differentiation to mature type II cells during recove...

OBJECTIVE To detect and explain changing trends in incidence, case fatality rates, and mortality for unintentional injuries in the Netherlands for the years 1950 through 1995. METHODS Using national registry data, the authors analyzed trends in traffic injuries, occupational injuries, and home and leisure injuries. RESULTS Between 1950 and 1970, mortality from unintentional injuries rose, r...

We sought to assess the outcome of large retroperitoneal vascular injury that occurred during operative laparoscopy but was not related to trocar or Veress needle injury. We conducted a retrospective review of cases operated and reviewed by our centres. Eight cases were identified. Four women were undergoing lymphadenectomy, where vascular injury is a recognized risk. Distorted anatomy was a co...

BACKGROUND When performing follicular unit extraction (FUE), various types of minor hair follicle trauma unapparent during follicular unit strip surgery are likely to occur. However, no studies have examined such damage. METHODS In total, 100 grafts were randomly selected from each of 42 patients who underwent FUE with a 1-mm-diameter sharp punch. A ×5.5 magnifying loupe and a ×60 magnifying ...

the sharp upper bounds and the sharp lower bounds of the largest eigenvalues $lambda_1$, the least eigenvalue $lambda_n$, the second largest eigenvalue $lambda_2$, the spread and the separator among all firefly graphs on $n$ vertices are determined.

We provide generalisations of two Schwarz-type lemmas — the first a result of Globevnik and the other due to Ransford and White — for holomorphic mappings into the spectral unit ball. The first concerns mappings of the unit disc in C into the spectral unit ball, while the second concerns self-mappings. The aforementioned results apply to holomorphic mappings that map the origin to the origin. W...

We show that an essential part of the new (Jones-type) polynomial link invariants can be computed in subexponential time. This is in a sharp contrast to the result of Jaeger, Vertigan and Welsh that computing the whole polynomial and most of its evaluations is #P-hard.
