Performing quantitative sampling and determining faunistic analyses of dipterans is of fundamental importance in the analysis of ecological behavior, such as population dynamics and diversity, among other factors, for exotic and native species of necrophagous dipterans, so it is important to observe the type of bait used in traps to capture these dipteran species. This work aims to study structural parameters and faunistic indices of the diversity of Calliphoridae and Mesembrinellidae species as well as the abundance and diversity of species attracted to liver in two stages of decomposition: fresh liver and liver at 48 h of putrefaction. A total of 2826 dipterans were collected during the period from May 2021 to February 2022.

The determination of the synanthropic index is essential to evaluate the degree of association between species, such as diptera and man, based solely on their degree of preference for urban areas. This research aimed to study the synanthropic behavior of Calliphoridae and Mesembrinellidae flies in Rio de Janeiro, Brazil. The experiment was conducted between 2021 and 2022 in three areas, where four traps containing 300 g of fresh liver or with 48 h of putrefaction were installed, remaining exposed for 48 h; after collection the dipterans were sacrificed and taxonomically identified.

This study checked the biological response of Chrysomya putoria pupae to submersion in fresh water for up to 6 d, evaluating the critical submersion time, survival rate, and development time of the flies. Adults were collected using fish baits in two typical traps.

Researches regarding the flight behavior and the influence of abiotic factors on these insects may assist the application of entomology sciences. This study aimed to analyze the population fluctuation of Calliphoridae and Mesembrinellidae, verifying the influence of environmental factors, trap height, and the anthropic effect in the Itaipu-Piratininga lagoon complex, Niterói (RJ).

They carry various pathogens and cause myiasis in humans and livestock, but they are useful to forensic entomology and in larval therapy. Mesembrinellidae flies, formerly classified in the family Calliphoridae, are good bioindicators of human interference in natural environments.

Study of cadaveric fauna in various environments is primary as source of information to support this science. This study collected information about the fauna of Calliphoridae associated to carcasses of Rattus rattus in the Tijuca National Park, RJ.

We document the first cases of human myiasis by Lucilia cuprina (Wiedemann, 1830) in Rio de Janeiro, Brazil, analyzed the epidemiological and clinical profiles of the patients, and their risk factors associated with the occurrence of the disease. Between May 2008 to July 2013, six cases of myiasis caused by larvae of L.

In the absence of prophylaxis, around 75% of patients undergoing SCT experience delayed CINV. With first-generation 5-HT(3) receptor antagonists, only about 20% are completely protected from nausea and vomiting, and this frequent and debilitating adverse event has not been fully addressed.

The decision of whether to offer a patient a hematopoietic stem cell transplant (HSCT) must be based on the probability of success of the procedure. The aim of this retrospective analysis of 1,084 CML patients who received an allogeneic HSCT in 10 Brazilian Centers between February 1983 and March 2003 was to validate the EBMT risk score.

In addition, the impact of the immunolocalization of VEGF on the survival rate of BMT patients was investigated as well.
Methods: Labial salivary glands obtained at the day 100+ from 36 consecutive patients, who underwent BMT, were included in the study.
