Essential oil of Aloysia citriodora Paláu and citral: sedative and anesthetic efficacy and safety in Rhamdia quelen and Ctenopharyngodon idella.

Objective: To verify the efficacy of citral in inducing sedation and anesthesia in silver catfish (Rhamdia quelen) and grass carp (Ctenopharyngodon idella) and to assess the safety of essential oil (EO) of Aloysia citriodora and citral in inducing and maintaining anesthesia in silver catfish.

Study Design: Clinical study, randomized, parallel, multi-arm with control group in target species.

Animals: A total of 96 juvenile and 72 adult silver catfish and 80 juvenile grass carp were used.

Citrobacter freundii infection in silver catfish (Rhamdia quelen): Hematological and histological alterations.

Citrobacter freundii is a fish pathogen known for its ability to cause injury and high mortality. There have been no studies reporting the effect of this bacterium on hematological parameters and internal organ histology in silver catfish (Rhamdia quelen). Therefore, the aim of this study is to evaluate the hematological and histopathological effects of an experimentally induced C.

Aloysia triphylla in the zebrafish food: effects on physiology, behavior, and growth performance.

Dietary supplements are commonly used by animals and humans and play key roles in diverse systems, such as the immune and reproductive systems, and in metabolism. Essential oils (EOs), which are natural substances, have potential for use in food supplementation; however, their effects on organisms remain to be elucidated. Here, we examine the effects of dietary Aloysia triphylla EO supplementation on zebrafish behavior, metabolism, stress response, and growth performance.

Aloysia triphylla essential oil as additive in silver catfish diet: Blood response and resistance against Aeromonas hydrophila infection.

The essential oil of Aloysia triphylla (EOAT) is a promising product with potential use in aquaculture systems. This study evaluated hematological/biochemical responses and survival of silver catfish (Rhamdia quelen) fed a diet containing EOAT and infected by Aeromonas hydrophila. After 21 days of feeding trial, fish were infected with A.

Anesthesia and anesthetic action mechanism of essential oils of Aloysia triphylla and Cymbopogon flexuosus in silver catfish (Rhamdia quelen).

Objectives: To document the time for anesthesia induction and recovery using different concentrations of essential oils (EOs) of Cymbopogon flexuosus and Aloysia triphylla in silver catfish (Rhamdia quelen), and to determine whether the mechanism of action of either EO involves the benzodiazepine (BDZ) site of the GABA receptor.

Study Design: Experimental study.

Animals: A total of 144 silver catfish, length 7.

Seroprevalence of HTLV-1/2 among blood donors in the state of Maranhão, Brazil.

Background: Infection with human T-lymphotropic virus 1 or 2 (HTLV-1/2) is a major health problem. There is a public health policy defining measures for state hematology and hemotherapy centers in Brazil, in order to avoid virus transmission through blood donors.

Objective: This study aimed to evaluate the seroprevalence of HTLV -1/2 in blood donors in the State of Maranhão, Brazil, during routine blood unit screening.

Evaluation of laboratory markers of progression of HIV disease to death.

Introduction: One of the important current problems in HIV/AIDS infection is the establishment of epidemiological and laboratorial prognostic parameters during patient follow-up. This study aimed at analyzing the evolution of laboratory tests: CD4 lymphocyte count, viral load, hemoglobin (Hb), aspartate aminotransferase (AST), alanine aminotransferase (ALT), and the epidemiological variables sex and age as prognostic factors for survival in progression to death among AIDS patients.

Methods: A retrospective study was conducted using analysis of medical records, and prospective 24-month follow-up of patients with HIV/ AIDS attended at the President Vargas Hospital Outpatient Clinic, a reference center in HIV/AIDS attendance in the State of Maranhão, Brazil.

Relationship between rainfall and temperature: observations on the cases of visceral leishmaniasis in São Luis Island, State of Maranhão, Brazil.

Introduction: Visceral leishmaniasis is a serious public health problem that requires global control strategies, especially with respect to factors that may intervene in reducing the incidence of endemicity. In this work, rainfall density and temperature were correlated with the incidence of human cases in an area endemic for leishmaniasis in São Luis do Maranhão, Northeastern Brazil.

Methods: Notification of human cases by the National Health Foundation/Regional Coordination of Maranhão (FUNASA/COREMA) from 2002 to 2010 was used.
