Early‐Life Nutritional Disruption Reshapes Gastric Epithelial Development Through Coordinated Changes in the Dynamics and Signaling of Proliferative Niches
Gastric gland cells originate from two proliferative niches: the main rapid one in the isthmus, and the slow secondary one in the base. However, while nutrition is dependent on breastfeeding, the proliferative niches are not established, and proliferation occurs along the gland. Currently, we investigated the influence of early weaning (EW) on shaping gastric proliferative niches and their signaling. Wistar rats were separated into suckling (S) and EW groups on postnatal day (PND) 15 for gastric mucosa collection. BrdU was administered (PND 14 and 15) and as it diluted between daughter‐cells we evaluated migration and differentiation. In parallel EdU incorporation was used to identify cells during S phase. Through these tools, we studied the different profiles of BrdU/EdU dual labeling at 18, 21 and 30 PND. At 18 PND, EW decreased BrdU+ population ( p < 0.0001 vs . S group) in the upper and bottom gland areas ( p < 0.05). The BrdU + /EdU+ cells were concentrated in the upper gland, where we recorded a larger EdU+ population after EW ( p < 0.05). On PND 30, EW decreased BrdU+ cells in the gland ( p < 0.05), whereas EdU+ cells were more numerous in the isthmus. At 18 PND, EW reduced Wnt3 , Notch1 , and Notch2 expressions ( p < 0.05), while increasing Bmp2 . In contrast, at 60 PND, Axin2 , Notch1 , and Notch2 transcripts were elevated after EW ( p < 0.05). Notch1 and Notch2 distribution indicated that EW might shift Notch2 to the upper gland, potentially affecting the fate of progenitor cells in pups. In silico analyses showed that zymogenic cells are in a renewal‐promoting environment, while parietal cells contribute to differentiation and signaling. Therefore, EW restricted the proliferative activity to the isthmus, altering the spatiotemporal expression of genes involved in stemness and differentiation, and reshaped the distribution of Notch receptors, without affecting the distribution of its downstream effector Hes1. These spatially organized molecular landscapes are crucial for proper epithelial renewal and function, and our data suggest that early nutritional disruption reprograms these niches with long‐term consequences.

DETERMINANT ASPECTS OF THE REPRODUCTIVE SUCCESS OF Aedes aegypti (LINNAEUS, 1762): A REVIEW
The mosquito Aedes aegypti (Diptera: Culicidae) is a primary vector for arboviruses such as yellow fever (YFV), dengue (DENV), chikungunya (CHIKV), and Zika (ZIKV). Considering the significant medical and social impact of arboviruses, effective vector control measures are essential in reducing virus transmission. This review investigates key factors influencing the reproductive success of Ae. aegypti, crucial for understanding how to control its population. From an analysis of 30 articles in international databases, six major categories were identified: copulatory behavior, age and body size, harmonic convergence, locomotor activity, accessory gland products, and hormones. Males of Ae. aegypti display polygamous behavior, whereas females are relatively monogamous. Larger, older males transfer more sperm, enhancing fertilization rates, while harmonic convergence—synchronized wingbeat frequencies between males and females—improves reproductive success and offspring viability. Additionally, accessory gland proteins, particularly seminal proteins, significantly influence female reproductive physiology. Despite the critical role males play in mating and influencing female fertility, research on their contributions remains limited. Understanding these physiological and behavioral mechanisms is essential for developing more targeted vector control strategies, potentially curbing mosquito populations and reducing arbovirus transmission.

Toxicological evaluation and safety of the ethanol extract from leaves of Piptadenia stipulaceae
Piptadenia stipulacea is popularly known as “Jurema Branca” and is apply in empiric therapy as anti-inflammatory, analgesic, cells regenerator, antipyretic and astringent pectoral. The present work had as objective to carry out the toxicological analysis of the ethanol extract of the leaves of P. stipulacea. In vitro toxicity was performed according to the methodologies of osmotic fragility against sheep erythrocytes and genotoxicity by Allium cepa and in vivo toxicity according to the protocol of Organization for Economic Cooperation and Development (OECD 423). Erythrocyte osmotic fragility presented low levels of hemolysis both by the qualitative evaluation of the supernatant and by the hemolytic percentage result. In cytotoxic evaluation with Allium cepa, no chromosomal abnormalities or differences in the cell division process (interphase, prophase, anaphase metaphase and telophase) were identified between the control group and the groups submitted to the different concentrations of the ethanolic extract of the leaves of P. stipulaceae (50μg/mL, 500μg/mL and 1000μg/mL). The ethanolic extract of the leaves of P. stipulaceae can be considered of low acute toxicity, since it did not cause the death of treated animals at the dose of 2000 mg/kg, as recommended by OECD 423. The results obtained allow to proceed with additional tests of sub-acute and chronic toxicity, biological activities on specific organisms in order to define the low risk of this plant.

Influence of SARS-CoV-2 during pregnancy: a placental view
Since the beginning of the current coronavirus outbreak (COVID-19), there has been great concern over a disease that has spread rapidly in several countries worldwide, with the result of several deaths, including deaths of pregnant women. Therefore, the aim of this study was to conduct a literature review on placental changes in infected pregnant women and/or asymptomatic carriers of COVID-19 during pregnancy, aiming at the possible vertical transmission. A systematic collection was carried out on the effects of that COVID-19 can cause directly and/or indirectly to pregnancy and the placenta in the following databases: Pubmed, Science Direct, Scielo, Lilacs, and Web of Science. For search, the following descriptors were used: placenta, pregnant woman, COVID-19, maternal–fetal. The results indicate transplacental transmission in some cases reviewed in many reports from this study. The presence of the virus was seen in the amniotic fluid, umbilical cord, and peripheral blood. Finally, pathological studies suggest that there are morphological changes related to infection in the placentas. We can conclude that, based on the researched material, there is little evidence of transplacental vertical viral transmission and its respective morphological changes related to viral infection in the placenta.

Influência de constante iluminação, melatonina e geldanamicina sob o testículo de rato por mais de 60 dias
A melatonina (N-acetil-5-metoxitriptamina) é um hormônio secretado pela glândula pineal. Nos homens, a melatonina afeta a regulação reprodutiva de três maneiras principais. Primeiro, ele regula a secreção de GnRH e LH. Em segundo lugar, regula a síntese de testosterona e a maturação testicular. Terceiro, como um potente representante do radical livre que é tanto lipofílico quanto hidrofílico. O testículo de mamíferos é um órgão suscetível a agentes tóxicos ambientais e terapêuticos que comprometem a espermatogênese, o presente estudo teve como objetivo analisar a influência da iluminação constante, melatonina e geldanamicina sob o testículo de ratos tratados por 60 dias. Os machos foram divididos aleatoriamente em 4 grupos, cada um composto por 5 animais, sendo eles: Grupo I - ratos controle (não tratados); Grupo II - ratos submetidos à iluminação constante por 60 dias; Grupo III - ratos submetidos à iluminação constante por 60 dias e tratados com melatonina por 60 dias; Grupo IV - ratos submetidos à iluminação constante por 60 dias, tratados com melatonina e geldanamicina por 60 dias. A exposição à iluminação constante afeta o desenvolvimento do epitélio germinativo, bem como a diminuição do peso dos testículos, células de Leydig, Sertoli e testosterona. O tratamento com melatonina e geldanamicina tem um efeito protetor contra a iluminação constante, reduzindo os danos testiculares quando tomados em conjunto.

Isolamento social durante COVID-19 x adaptação da sociedade: uma coleta de dados
Objetivo: verificar se o isolamento social pode afetar a saúde mental das pessoas bem como os hábitos diários, atrelados a ideia de ser proibido sair de casa em decorrência da pandemia do COVID-19 do Estado de Pernambuco/PE. Metodologia: Tratou-se de um estudo transversal e quantitativo com 1.088 indivíduos, do tipo não probabilístico, por conveniência, de ambos os sexos e de diferentes idades, submetidos à um questionário virtual sobre as modificações cotidianas causadas pelo isolamento social, em decorrência da pandemia do COVID-19 do Estado Pernambuco/PE. O presente estudo teve como número de aprovação do comitê de ética 4.001.096. Resultados: A maior parte dos participantes foram sexo feminino, com idade média de 34,72 anos de idade, relatando não ter havido problemas referentes ao isolamento social, nem problemas familiares. A maioria precisou se adaptar a uma nova realidade sobre higienização e apresentaram sentimentos não sentidos antes da pandemia, afirmando medo, tanto da situação de uma forma geral como de ser infectado pelo COVID-19, como também o isolamento social desencadeou ansiedade e outros sentimentos não vivenciados antes da pandemia. Por fim, quase todos os participantes relataram acreditar que os pesquisadores irão descobrir um tratamento eficaz para o COVID-19. Conclusão: O isolamento social em decorrência da pandemia por COVID-19 pode afetar tanto a saúde mental dos indivíduos, desencadeando doenças psicoemocionais e como dificultar o processo de adaptação social.

Aspectos toxicológicos da ivermectina: um estudo dos efeitos na morfologia do fígado de ratas prenhes
A Ivermectina, princípio farmacológico de um medicamento de uso veterinário possui efeito antiparasitário contra endo e ectoparasitos, é amplamente utilizada na prática veterinária. Esta droga é biotransformada no fígado, resultando em 3 metabólitos, sendo o mais importante o 24-hidroxi-metil-diidroavermectina B1. O fígado é essencial na regulação do metabolismo, na síntese de certas proteínas, servindo como local de armazenagem para certas vitaminas e ferro, degradando certos hormônios e inativando e excretando certos medicamentos e toxinas. Portanto, este trabalho teve por objetivo avaliar a morfologia dos fígados de ratas prenhes tratadas com ivermectina. Para tanto foram utilizadas 30 ratas albinas, as quais foram divididas em 3 grupos de 10 animais. Os animais foram colocados para acasalar e após a detecção da prenhez, presença de espermatozóides no esfregaço vaginal realizado na manhã do dia seguinte, sendo assim designado o primeiro dia de gestação, cada animal foi tratado com ivermectina, na dose correspondente a cada grupo durante 18 dias, com administração a cada 3 (três) dias, totalizando 6 administrações. Após esse período o fígado foi coletado, pesado em balança analítica e processado para microscopia de luz. A análise do peso relativo dos fígados das ratas prenhes e não prenhes não revelou diferença significativa entre os grupos experimentais, onde o tratamento com ivermectina nas doses de 4,0 e 8,0 mg/kg não alterou a massa relativa do fígado, nem apresentou alterações na cor, textura, consistência e hemorragias. Com relação ao estudo através da microscopia de luz, não foram observadas alterações histopatológicas.
