INTRODUCTION Facial and neck hematomas are a significant complication of surgical procedures and direct trauma. Effective treatment of these hematomas is crucial for the prevention of cosmetic deformity, functional disturbance, infection, and tissue necrosis. Current treatment options include aspiration, incision and drainage, steroid injection, and drainage tube placement. However, these metho...

Loxoscelism is the designation given to clinical symptoms evoked by Loxosceles spider's bites. Clinical manifestations include skin necrosis with gravitational spreading and systemic disturbs. The venom contains several enzymatic toxins. Herein, we describe the cloning, expression, refolding and biological evaluation of a novel brown spider protein characterized as a hyaluronidase. Employing a ...

BACKGROUND Hyaluronidases are essential for the breakdown of hyaluronate (HA) in tissues and may be used to prevent the adverse effects of HA fillers. OBJECTIVES We explored the effect of hyaluronidase on exogenous and endogenous HA in vitro and in vivo. MATERIALS AND METHODS HA fillers were incubated with different concentrations of hyaluronidase and visualized by electrophoresis. HA fille...

A hierarchical framework is proposed to address the issues of modeling different type of words in keyword spotting (KWS). Keyword models are built at various levels according to the availability of training set resources for each individual word. The proposed approach improves the performance of KWS even when no training speech is available for the keywords. It also suggests an easier way to co...

Hyaluronidase is an enzyme that has temporary and reversible enzymatic effects on the matrix of connective tissue. When added to local anesthetics in pain treatments, it enhances their infiltration and dispersal into tissues. It is widely used in anesthesia for ocular, dental, and plastic surgery. Reports of drug hypersensitivity to hyaluronidase are rare and are usually confined to peribulbar ...

It has been reported that a polysaccharide extracted from Pseudomonas aeruginosa is depolymerized by bovine testicular hyaluronidase (Warren and Gray, 1954). In the course of studies dealing with the effect of hyaluronidase on the cell structure of the organism, it was noted that buffered suspensions of P. aeruginosa released appreciable amounts of the polysaccharide in the supernatant fluid wh...

Hyaluronidase has been gaining interest because it reduces tissue edema and fibrosis. Although rare, hyaluronidase has been shown to cause allergic reactions. A few cases of allergic reactions following hyaluronidase administration have been reported. Most of the described patients presented allergic reactions after peribulbar anesthesia for eye surgery. In this report, we describe three patien...

The reaction between normal serum and hyaluronidase has been studied in vitro and under in vivo conditions in skin. Using in vitro conditions of incubation, serum exhibits antihyaluronidase activity as measured by assay of hyaluronidase spreading activity in skin. This confirms the work of others, who have previously described the serum inhibitory factor using other tests of hyaluronidase activ...

Chang, Nan-Shan. Hyaluronidase enhancement of TNFmediated cell death is reversed by TGF-b1. Am. J. Physiol. 273 (Cell Physiol. 42): C1987–C1994, 1997.—Both hyaluronidase and transforming growth factor (TGF)-b1 play a significant role in the development of prostate cancer. In this study, the regulation of tumor necrosis factor (TNF)-mediated cell death by hyaluronidase and TGF-b1 was investigate...
