1. O laser de baixa potência seria terapêutico para lesões causadas por acidentes ofídicos do gênero Bothrops?
Ainda não há evidências científicas em humanos, entretanto, em caráter experimental e de pesquisa, a laserterapia tem sido usada em lesões necróticas incapacitantes secundárias à picada por serpente na região amazônica, devido seu importante impacto em saúde pública pela retirada precoce do trabalhador na geração de renda. Assim, os benefí

2. Como investigar um resultado de ferritina elevado?
Os casos de hiperferritinemia devem ser inicialmente investigados repetindo-se a dosagem de ferritina, além da dosagem de saturação de transferrina e hemograma com plaquetas. Deve-se investigar se o paciente tem história familiar de sobrecarga de ferro ou cirrose, história de reposição de ferro em excesso ou sobrecarga secundária a transfusões, u

3. Qual o protocolo para atendimento odontológico ao paciente com diabetes mellitus e doença periodontal?
No que se refere ao atendimento odontológico de paciente com diabetes mellitus (DM) e doença periodontal, os estudos têm demonstrado que o tratamento da periodontite por meio da terapia mecânica convencional (raspagem e alisamento radicular), além de promover a melhora na saúde periodontal é capaz de também promover melhorias na saúde sistêmica.

5. Vitamin D deficiency in bedridden elderly people at home
SUMMARY OBJECTIVE: The aim of this study was to evaluate serum 25(OH)D concentrations in the homebound elderly people and relate them to level of dementia, nutritional risk, and route of dietary administration. METHODS: This is a cross-sectional study involving 207 bedridden elderly people assisted by the Home Care Service in the city of Santo André – S

6. Evaluation of toxin-antitoxin genes, antibiotic resistance, and virulence genes in Pseudomonas aeruginosa isolates
SUMMARY OBJECTIVE: Toxin-antitoxin genes RelBE and HigBA are known to be involved in the formation of biofilm, which is an important virulence factor for Pseudomonas aeruginosa. The purpose of this study was to determine the presence of toxin-antitoxin genes and exoenzyme S and exotoxin A virulence genes in P. aeruginosa isolates and whether there is a rela

7. Sedimentation and rheological behavior of reactive and non-reactive magnesium hydroxide pulps for industrial spray dryer processing
Abstract Two different reactive concentrated magnesium hydroxide (HM) pulps, produced in a lab reactor mill, and a synthetic and non-reactive HM-pulp, for comparative analyses, have been prepared and studied. Sodium polyacrylate was selected as a dispersant for improving the HM pulp fluidity, with concentrations varying from 0.42% to 2.0% on a dry basis. The

8. Carbon Dots from Pilosocereus gounellei for Fluorimetric Determination of Tannin in Tea Using a Flow-Batch System
In this study, xiquexique (Pilosocereus gounellei) native endemic cactus from the Brazilian semiarid was used for the first time as a natural carbon source (“green precursor”) for the synthesis of highly fluorescent carbon dots (CDs). These CDs were successfully used to develop a fast, low-cost, eco-friendly fluorescence method for the determination of t

9. Nicotine as a Catalyst for Chlorination Promoted by Hypochlorous Acid: Experimental and Theoretical Studies
There is robust evidence of the hypochlorous acid (HClO)-mediated damage in biomolecules, and nicotine boosts the chlorination potency of HClO. We present experimental and theoretical evidence of the mechanism by which nicotine catalyzes the chlorination of pyranine. The rate constants for chlorination of pyranine by HClO were measured in the presence (5.3 �

10. Encoding of Luminescent Ink Markers Using Low-Level Data Fusion and Chemometrics
The identification and analysis of documentary fraud is always a challenge for forensic science. Document analysis has proven to be an important branch of forensics in elucidating the authenticity of documents. The development and incorporation of luminescent inks in authentic documents have proved to be an excellent security feature. This paper purposes the

12. Sowing date influence on the soybean tolerance to defoliation at the beginning of pod formation
ABSTRACT Late sowings anticipate flowering and decrease the soybean vegetative plasticity. These changes may limit the ability of plants to tolerate leaf area losses. The objective of this research was to evaluate the sowing date effect on soybean tolerance to defoliation at the beginning of pod formation. The experiment was set in Lages (Santa Catarina Stat
