Laboratory evaluation of repellency of traditional Czech homemade repellents against Aedes aegypti.

Objectives: In the Czech Republic, autochtonous transmission of mosquito borne diseases is not common; however, the need for personal protection should not be underestimated. Many people still rely on homemade repellents utilizing recipes based on local folk wisdom that are published annually in local Czech media. Despite minimal disease risk, nuisance biting and potential allergic responses make it essential to evaluate the chemical composition, effect, and duration of four homemade repellents often used and determine the necessity for public health education on application and use of alternative repellent products.

[Surgical treatment of patients with gastrointestinal stromal tumor of the stomach].

Aim: to evaluate objectively the effectiveness of currently used diagnostic and curative approaches to gastrointestinal stromal tumors (GIST).

Material And Methods: Early and remote results of treatment of 49 patients with gastric GISTs were presented. Herewith in 20 (40.

Seasonal Dynamics, Parity Rate, and Composition of Culicoides (Diptera: Ceratopogonidae) Occurring in the Vicinity of Wild and Domestic Ruminants in the Czech Republic.

In the light of the emergence of bluetongue and Schmallenberg viruses in northern and central Europe, an extensive entomological survey within the framework of a bluetongue control program was undertaken from 2008 to 2013 in the Czech Republic to investigate Culicoides biting midges (Diptera: Ceratopogonidae) collected in close proximity of domestic livestock and semiwild ruminants. Insects were sampled using CDC black-light suction traps placed overnight near ruminants in farms or in forest game preserves to provide data on Culicoides fauna collected near these two groups of hosts inhabiting different environments. From almost a half million biting midge specimens collected at 41 sampling sites, 34 species were identified including three species newly recorded for the Czech Republic: Culicoides (Oecacta) clastrieri Callot, Kremer & Deduit, Culicoides (Oecacta) odiatus Austen, and Culicoides (Pontoculicoides) saevus Kieffer.

[APPLICATION OF HD-VIDEOENDOSCOPY, MAGNIFYING ENDOSCOPY AND NARROW BAND IMAGING TECHNIQUE FOR THE DIFFERENTIAL DIAGNOSIS OF BENIGN AND NEOPLASTIC EPITHELIAL LESIONS IN THE STOMACH. THE POTENTIAL OF THE COMPUTER-AIDED ANALYSIS].

An endoscopic diagnosis of superficial epithelial neoplastic gastric lesions and early gastric cancer is the challenge of medicine today. It remains at a low level without the use of modern endoscopic technologies such as HDTV and magnifying endoscopy, narrow band imaging (NBI) and similar image-enhanced endoscopic methods, which provide the visualization of microsurface and microvascular pattern. There are a few endoscopic classifications of microsurface and microvascular patterns to distinguish benign and neoplastic superficial gastric epithelial lesions.

[Modern endoscopic diagnosis of precancerous lesions and early cancers of the stomach and colon using computer decision support systems].

Modern endoscopic techniques allow a precise diagnosis of superficial epithelial lesions of the stomach and colon and predict their histological structure. Currently, there are a variety of endoscopic classifications based on the use of magnifying endoscopy and NBI for superficial epithelial lesions according to their morphology. For differential diagnosis of benign lesions, mild neoplasia and early cancer in the colon we commonly use the pit-pattern classification of the surface epithelium created by S.
