Botryomycosis is an uncommon, chronic infection of the skin most often caused by Staphylococcus aureus. It has been successfully treated using carbon dioxide laser vaporization in a case in which antibiotic therapy failed, and surgical excision was not feasible.

to evaluate the effects of various concentration of carbon dioxide and salinity stress on morphophysiological characteristics of amaranthus tricolor l. an experiment was conducted in greenhouse conditions in faculity of agriculture ferdowsi university of mashhad. the experiment was split plot based on completely randomized design with three levels of co2 (380, 700, 1050 µl/l) and three concentr...

BACKGROUND Fractionated ablative laser resurfacing has become a widely used treatment modality. Its clinical results are often found to approach those of traditional fully ablative laser resurfacing. OBJECTIVE To directly compare the molecular changes that result from fractionated and fully ablative carbon dioxide (CO(2)) laser resurfacing in photodamaged human skin. METHODS AND MATERIALS P...

Pontryagin's principle is used to study the shape of the supersonic part of the nozzle of a carbon dioxide gas-dynamic laser whose gain is maximal. The exact shape is obtained for the uncoupled approximation of Anderson's bimodal model. In this case, if sharp corners are allowed, the ceiling of the supersonic part consists of a slant rectangular sheet followed by a horizontal one; otherwise...

CS2 hydrolase, a zinc-dependent enzyme that converts carbon disulfide to carbon dioxide and hydrogen sulfide, exists as a mixture of octameric ring and hexadecameric catenane forms in solution. A combination of size exclusion chromatography, multi-angle laser light scattering, and mass spectrometric analyses revealed that the unusual catenane structure is not an artefact, but a naturally occurr...

introduction: the aim of this study was to investigate the morphological changes of human dentin after erbium-doped yttrium aluminum garnet (er:yag), carbon dioxide (co2) laser-irradiation and acid-etching by means of scanning electron microscopic (sem) m ethods: 9 extracted human third molars were used in this study. the teeth were divided in three groups: first group, co2 laser with power of ...

OBJECTIVES To determine the role of the main cartilage components in the internal system of interlocked stresses and to clarify the effect of laser beam irradiation on cartilage. DESIGN Control and experimental series. SUBJECTS Rabbit ear cartilage. INTERVENTION Rabbit ear cartilage strips incubated in collagenase and hyaluronidase enzyme solutions for specific periods were examined, and ...
