Evaluation of the skin whitening and antioxidant activity of < em > Myracrodum urundeuva < /em > extract (aroeira-do-sert ão)
Nat Prod Res. 2023 Sep 11:1-6. doi: 10.1080/14786419.2023.2254457. Online ahead of print.ABSTRACTMyracrodruon urundeuva, popularly known as 'aroeira-do-sertão', a large tree, with a tall trunk. Belonging to the Anacardiaceae family, it occurs in the 'caatinga' and dry forests of Brazil, from Ceará to the states of Paraná and Mato Grosso do Sul. The present study aimed to analyse the whitening and antioxidant activities of the aqueous extract of the leaves of Myracrodroun urundeuva (AELMU). Inhibition of the tyrosinase enzyme, as well as its copper chelating capacity and antioxidant effect were evaluated. The AELMU (at 2...

Anthropic Impact on the Critically Endangered Melanophryniscus admirabilis (Admirable Redbelly Toad): Evidence from the Presence of Multiresistant Enterobacteriaceae
Curr Microbiol. 2023 Sep 11;80(11):339. doi: 10.1007/s00284-023-03433-7.ABSTRACTMelanophryniscus admirabilis is a microendemic and critically endangered toad, known from a single population. This microendemic species inhabits a small fragment of the Atlantic Forest in South Brazil, an area significantly impacted by hydroelectric power plant projects, livestock farming, agricultural activities, biopiracy, and tourism. Given the exclusive and limited population of M. admirabilis, preserving and conserving this species is of utmost importance in Brazil. Research on this species primarily concentrates on its biology, ecology, ...

The effects of social jetlag and sleep variability on sleepiness in a population-based study: The mediating role of sleep debt
In conclusion, the association between social jetlag and sleepiness was mediated by sleep debt but was not independent of demographic, work, and chronotype variables. This study provides new evidence on the importance of circadian misalignment and sleep debt for sleep health on a population level.PMID:37691450 | DOI:10.1111/jsr.14043

A predatory social wasp does not avoid nestmates contaminated with a fungal biopesticide
Environ Sci Pollut Res Int. 2023 Sep 11. doi: 10.1007/s11356-023-29770-5. Online ahead of print.ABSTRACTFungus-based biopesticides have been used worldwide for crop pest control as a safer alternative to chemical pesticides such as neonicotinoids. Both agrochemicals can be lethal and may also trigger side effects on the behavioral traits of non-target social insects, which play a crucial role in providing essential biological pest control services in agroecosystems. Here, we evaluated whether a commercial formulation of the entomopathogenic fungus Beauveria bassiana or the neonicotinoid imidacloprid causes mortality in for...

Systematic Review and Meta-analysis of laparoscopic radical hysterectomy vs. Robotic assisted radical hysterectomy for early stage cervical cancer
CONCLUSIONS: RRH seems to result in the patient leaving the hospital sooner after surgery. We were unable to find any differences in our ten other outcomes related to complications or efficacy. These findings suggest that the decreased survival seen in minimally invasive RH in previous studies could be due to factors inherent to both LRH and RRH.PROSPERO PROSPECTIVE REGISTRATION NUMBER: CRD42022273727.PMID:37690282 | DOI:10.1016/j.ejogrb.2023.09.002

Ecotoxicology applied to conservation: Potential negative metal and metalloid contamination effects on the homeostatic balance of the critically endangered Brazilian guitarfish, Pseudobatos horkelii (Elasmobranchii: Rhinobatidae)
Chemosphere. 2023 Sep 8:140119. doi: 10.1016/j.chemosphere.2023.140119. Online ahead of print.ABSTRACTMetal contamination poses a significant threat to elasmobranchs, underscoring the need for targeted conservation approaches. The critically endangered Brazilian guitarfish, Pseudobatos horkelii, confronts an array of challenges, notably overexploitation, putting its survival at risk. Our study investigated the potential toxicity arising from arsenic (As), cadmium (Cd), mercury (Hg), and lead (Pb) contamination across various adult guitarfish tissues from southeastern Brazil. Serological stress indicators, nutritional metab...

The impact of transformation zone representation on the frequency of abnormal cervical cytological results
CONCLUSION: Samples with TZ representation were associated with higher rates of abnormal results. Health professionals should be regularly trained to understand the weakness of cytological examinations when the TZ is not represented, especially in developing countries.PMID:37688813 | DOI:10.1016/j.ejogrb.2023.08.394

Recombinant antigen 5 from Polybia paulista wasp venom (Hymenoptera, Vespidae): Antigen-specific antibody production and functional profile of CD4 < sup > + < /sup > T cells in the immune response
J Immunol Methods. 2023 Sep 7:113557. doi: 10.1016/j.jim.2023.113557. Online ahead of print.ABSTRACTPolybia paulista is a neotropical social wasp related to severe accidents and allergic reactions cases, including anaphylaxis, in southeastern Brazil. Antigen 5 (Poly p 5) is a major allergenic protein from its venom with potential use for component-resolved diagnostic. Therefore, the previous characterization of the immune response profile triggered by Poly p 5 should be evaluated. Recombinant Poly p 5 (rPoly p 5) was used to sensitize BALB/c mice with six weekly intradermal doses, and the specific antibody production and t...

Mobilome characterization of the beetle Euchroma gigantea (Buprestidae) uncovers multiple long range Tc1-Mariner horizontal transfer events
Gene. 2023 Sep 7:147785. doi: 10.1016/j.gene.2023.147785. Online ahead of print.ABSTRACTTransposable elements (TEs) are mobile repetitive DNA sequences that can transfer horizontally between species. Due to their mutagenic characteristics, TEs are associated with different evolutionary events, including chromosomal rearrangements that are abundant in the beetle Euchroma gigantea. In order to understand more in depth the impact of TEs on the genomic evolution of E. gigantea, we characterized the E. gigantea mobilome and evaluated the horizontal transfer transmission mode of Tc1-Mariner elements. Genomic sequencing data was ...
