In the present contribution we compared the entomological succession pattern of a burned carcass with that of an unburned one. For that, we used domestic pig carcasses and focused on Calliphoridae, Muscidae and Sarcophagidae flies, because they are the ones most commonly used in Postmortem Interval estimates. Adult and immature flies were collected daily. A total of 27 species and 2,498 specimens were collected, 1,295 specimens of 26 species from the partially burned carcass and 1,203 specimens of 22 species from the control carcass (unburned). The species composition in the two samples differed, and the results of the similarity measures were 0.875 by Sorensen and 0.756 by Bray-Curtis index. The results obtained for both carcasses also differ with respect to the decomposition process, indicating that the post mortem interval would be underestimated if the entomological succession pattern observed for a carcass under normal conditions was applied to a carbonized carcass.

Article Synopsis
- The study focuses on the unique enzyme arginyl-tRNA synthetase (TcArgRS) from Trypanosoma cruzi, the cause of Chagas disease, as a potential target for drug development.
- Naphthalene-derived fluorescent ligands like ANS and bis-ANS are explored for their ability to help visualize protein interactions and conformational states, showing noticeable changes in their fluorescence when binding to TcArgRS.
- The findings suggest that analyzing the hydrophobic regions of TcArgRS can aid in identifying drug targets, indicating that these regions are essential for developing treatments for Chagas disease.
Enhancing the Thermal Stability and Combustion Performance of NC-Based Propellants via Bu-NENA Modification.

Article Synopsis
- Researchers developed new smokeless propellants using an absorption rolling method, enhancing thermal stability by replacing nitroglycerin (NG) with -butyl--nitratoethyl nitramine (Bu-NENA).
- The study used various testing methods to analyze thermal stability, combustion characteristics, and the effects of Bu-NENA on burning rates and flame temperatures.
- Results indicated that while increasing Bu-NENA improved thermal stability, it also lowered the burning rate and flame temperature due to heat absorption during its volatilization.

Article Synopsis
- Genetic diseases that cause skin fragility are diverse in their symptoms and genetic causes, making it crucial for healthcare professionals to differentiate them from more common conditions like infections or burns.
- The classification of these rare diseases is guided by their clinical presentation, histological characteristics, and genetic mutations, with most treatments being symptomatic rather than curative.
- Advances in genetic testing have integrated the study of these rare diseases into everyday clinical practice, emphasizing the need for collaboration among specialists to ensure proper diagnosis and care for affected children.

The purpose of this study is to describe the development and initial validation of a survey focused on problematic situations involving e-cigarette use by rural Native Hawaiian and Pacific Islander (NHPI) youths. A 5-phase approach to test development and validation was used. In Phase 1 (Item Generation), survey items were created from a series of focus groups with middle school youths on Hawai'i Island ( = 69).
