1. Healing effects of natural latex serum 1% from Hevea brasiliensis in an experimental skin abrasion wound model,
Abstract Background Dermabrasion is related with mechanical and surgical traumas on the skin; usually topical antiseptics and/or saline have been used for healing. Natural products for wound healing can also be used for abrasions, such as latex from Hevea brasiliensis. Objective This study aimed to evaluate the in vitro viability and migratory/proliferativ

2. Fatty acid composition of vegetable oil blend and in vitro effects of pharmacotherapeutical skin care applications
Vegetable oils have been used for a plethora of health benefits by their incorporation in foods, cosmetics, and pharmaceutical products, especially those intended for skin care. This study aimed to investigate the cutaneous benefits of a vegetable oil blend (VOB) formulation and its fatty acid composition. The anti-inflammatory activity was studied in macrop

3. Micro-Scale Abrasive Wear Testing of CrN Duplex PVD Coating on Pre-Nitrided Tool Steel
Specific wear rates were calculated from a series of micro-scale abrasive tests by means of the calotte-grinding method. The tested material was a CrN coating deposited by arc evaporation on ion-nitrided AISI H13 steel. Characterizations included: phase analysis, chemical composition, metallography, microhardness, micro-scratch resistance and nano-indentatio

4. Modificação da superfície do aço para melhorias na aderência de filmes de DLC / Steel surface modification for DLC films adhesion improvements
Em vista das excelentes propriedades físico-químicas dos filmes de carbono tipo-diamante (Diamond like Carbon-\textit{DLC}), atualmente, existe uma corrida científica e tecnológica para o desenvolvimento deste revestimento sobre superfícies metálicas em geral e, em especial, aquelas à base de ferro. A partir do momento em que se alcançarem melhorias

5. Cervical Cat Scratch Disease Lymphadenitis in a Patient with Immunoglobulin M Antibodies to Toxoplasma gondii
We report on a young patient with chronic cervical lymphadenopathy and serological and histological evidence for infection with Bartonella henselae and Toxoplasma gondii. Serological follow-up studies, including testing for avidity of Toxoplasma-specific immunoglobulin G antibodies, assisted in the determination of the cause of the acute lymphadenitis. Our r

6. The utility of testing tactile perception of direction of scratch as a sensitive clinical sign of posterior column dysfunction in spinal cord disorders.
Classical beliefs about the functions of the dorsal columns of the spinal cord have been attacked following recent evidence that position and vibration sensations may be carried in the dorsal spinocerebellar tracts. There is evidence that the one specific function of the dorsal columns is for the transmission of information concerning the direction of tactil

7. Molecular diagnosis of cat scratch disease: a two-step approach.
Amplification of Bartonella henselae DNA has been proposed as a diagnostic test for cat scratch disease (CSD). The sensitivities of the following three PCR assays were compared. PCR/rRNA with universal primers amplifies part of the 16S rRNA gene, followed by hybridization with a specific B. henselae probe; PCR/CS and PCR/HSP amplify portions of the gltA and

8. Indirect enzyme-linked immunosorbent assay for measurement of human immunoglobulins E and G to purified cow's milk proteins: application in diagnosis of cow's milk allergy.
An indirect double-antibody enzyme-linked immunosorbent assay (ELISA) was developed for the measurement of human immunoglobulin E (IgE) and IgG to the cow's milk proteins (CMP) alpha-casein, alpha-lactalbumin, and beta-lactoglobulin. Human serum albumin was used as the negative-antigen control. Rabbit anti-human IgE or IgG served as the primary antibody, and

9. Seroprevalence of Antibodies to Bartonella henselae in Patients with Cat Scratch Disease and in Healthy Controls: Evaluation and Comparison of Two Commercial Serological Tests
Serologic testing for the presence of antibodies to Bartonella henselae is a widely accepted diagnostic procedure for laboratory confirmation of the diagnosis of cat scratch disease (CSD). In this study a commercially available indirect immunofluorescence assay (IFA) based on B. henselae-infected human larynx carcinoma cells (test A) was evaluated. Sera from

10. Clinical and Pathologic Evaluation of Chronic Bartonella henselae or Bartonella clarridgeiae Infection in Cats
Human Bartonella infections result in diverse medical presentations, whereas many cats appear to tolerate chronic bacteremia without obvious clinical abnormalities. Eighteen specific-pathogen-free cats were inoculated with Bartonella henselae- and/or Bartonella clarridgeiae-infected cat blood and monitored for 454 days. Relapsing bacteremia did not correlate

11. Characterization of Bartonella clarridgeiae Flagellin (FlaA) and Detection of Antiflagellin Antibodies in Patients with Lymphadenopathy
Cat scratch disease (CSD) is a frequent clinical outcome of Bartonella henselae infection in humans. Recently, two case reports indicated Bartonella clarridgeiae as an additional causative agent of CSD. Both pathogens have been isolated from domestic cats, which are considered to be their natural reservoir. B. clarridgeiae and B. henselae can be distinguishe
