1. Detection of seasonal asymptomatic dermatophytes in Van cats
Abstract The Van cat is a domestic landrace found in the Van province of eastern Turkey. In this study, we aimed to determine the seasonal carriage of dermatophytes in Van cats without clinical lesions. A total of 264 hair specimens were collected from clinically healthy cats in and around the Van Province. Of these samples, 30.3% were obtained in spring, 30

2. Morfología comparada del esqueleto axial en la familia de cangrejos de agua dulce Trichodactylidae (Crustacea: Decapoda: Brachyura)
The axial skeleton is a complex structure of cuticular origin, formed by sclerotic plates of thoracic sternite and pleurites as well as its internal invaginations. The ventral characters of the axial skeleton, reflected externally in the suture lines of the thoracic sternum, are an important classification criteria for the current suprageneric system of Tric

3. Determinacao varietal em arroz.
A dificuldade crescente na identificacao varietal de sementes assemelhadas de arroz sugere a adocao de novos metodos ou a associacao de metodos conhecidos, para facilitar a determinacao da qualidade fisica das sementes. Por essa razao, descreveu-se morfologicamente e classificou-se, quanto aos testes de fenol e hidroxido de potassio, um grupo de 22 cultivare

4. ANATOMIA COMPARADA DO ESQUELETO ENDOFRAGMAL NA FAMÍLIA DE CARANGUEJOS DE ÁGUA DOCE TRICHODACTYLIDAE (CRUSTACEA: BRACHYURA)
In brachyuran crustaceans the endophragmal skeleton is the main support structure of the locomotory complex. Its origin is cuticular and it is formed by the sternite and pleurite plates of the eight thoracic somites and their internal invaginations. The ventral characters of the endophragmal skeleton, reflected externally in the suture lines of the thoracic

5. Síntese e caracterização de nanocompósitos de sílica mesoporosa com partículas magnéticas para dispositivos de liberação controlada de fármacos
Ordered mesoporous materials like SBA-15 posses a network of channels and pores of well-defined size in the nanoscale range. This particular pore architecture makes them suitable for hosting a broad variety of compounds into the silica matrix, resulting in very promising material for a broad range of applications, including magnetic carriers for drug deliver

6. "Influência de inibidores no comportamento de corrosão de aço CA-50 para armadura de estruturas de concreto" / Evaluation of the potent ial of addi tives as corrosion inhibitors of CA-50 carbon steel used as reinforcement in concretes.
In this work, various compounds were tested to evaluate their potential capability for their use as corrosion inhibitors of carbon steel reinforcement in concretes. The addit ives tested were sodium benzoate, polyethylene glycol, hexamethylenetetramine, benzot riazole and itrium carbonate. Initially, exploratory tests were carried out to select the ones to b

7. Disinfection of intracanal dentin by ND:YAG, HO:YAG and ER:YAG laser irradiation: an in vitro model / "Desinfecção da Dentina Radicular pela Irradiação dos Lasers de Nd: YAG e Er: YAG: um Modelo "in vitro""
SUMMARY Disinfection of intracanal dentin by Nd:YAG, Ho:YAG and Er:YAG laser irradiation: an in vitro model A possible cause for root canal failure is the persistence of bacteria that have colonized dentinal tubules. To reduce this risk and, if possible, to also shorten the time-consuming endodontic therapy, new equipment and materials are constantly being i

8. Diagnosis and management of cases of suspected dermatomycosis in The Netherlands: influence of general practice based potassium hydroxide testing.
BACKGROUND. Microscopy of a potassium hydroxide preparation of skin scrapings or nail clippings, although widely advocated as a test for dermatomycosis, is used in only a small proportion of cases. AIM. This study set out to investigate the effect of potassium hydroxide testing on the subjectively assessed probability that a dermatomycosis was present. METHO

9. Efficacy of the Ryu nonstaining KOH technique for rapidly determining gram reactions of food-borne and waterborne bacteria and yeasts.
A simple and rapid (< 60 s) nonstaining technique with 3% potassium hydroxide to determine Gram reactions was tested with 495 food-borne and waterborne bacteria and yeasts. In KOH, suspensions of gram-negative bacteria become viscous and string out. Gram-positive bacteria are not affected. There was 100% correlation between the KOH string test results and gr

10. Rapid method that aids in distinguishing Gram-positive from Gram-negative anaerobic bacteria.
Several species of anaerobic bacteria display variable Gram stain reactions which often make identification difficult. A simple, rapid method utilizing a 3% solution of potassium hydroxide to distinguish between gram-positive and gram-negative bacterial was tested on 213 strains of anaerobic bacteria representing 19 genera. The Gram stain reaction and KOH te

11. Comparison of Micro-ID, API 20E, and Conventional Media Systems in Identification of Enterobacteriaceae
The Micro-ID, a new identification kit for Enterobacteriaceae, consists of 15 biochemical tests, with substrates and reagents impregnated in filter paper disks. A 0.2-ml amount of an organism suspension equal to a 0.5 McFarland standard is pipetted into each of the compartments. After 4 h of incubation and addition of potassium-hydroxide (KOH) to the Voges-P
