Summary: This study demonstrated that LT-171-861 inhibits proliferation and induces apoptosis in multiple myeloma cells by promoting DNA damage repair pathway and impeding homologous recombination. The inhibition of Pim2 kinase activity by LT-171-861 leads to DNA damage and cell apoptosis, and the combination with PARP inhibitor Olaparib enhances its anti-tumor effect.

Summary: Glioblastoma multiforme (GBM) is a highly deadly brain tumor. UBA1 inhibition by TAK-243 can increase the sensitivity of GBM to radiotherapy by impairing DNA double-strand break repair. This study provides a new therapeutic strategy for improving the radiation sensitivity of GBM and lays a foundation for further clinical trials.

Summary: Nuclear atypia is a hallmark of cancer, and its immediate and long-term impact on cells can be determined through single-cell tracking studies. Multinucleation, a form of nuclear atypia, blocks cell proliferation in p53-compromised cells by increasing DNA damage and causing replication stress, suggesting potential therapeutic approaches for limiting tumor heterogeneity.

Summary: Through bioinformatics analysis, five key genes of GBC were identified, among which CEP55 was found to be overexpressed in GBC and associated with advanced TNM stage, differentiation grade, and poorer survival. Inhibition of CEP55 in GBC cells resulted in decreased proliferation, cell cycle arrest, DNA damage, and increased apoptosis. CEP55 inhibition in vivo attenuated tumor growth and promoted apoptosis in GBC cells. The tumor suppressor effect of CEP55 knockdown is mechanistically associated with dysregulation of the AKT and ERK signaling networks.

Summary: Arsenite stimulates crosstalk between IP3R and RyR by up-regulating ERO1α, leading to mitochondrial clearance of Ca2+ and triggering DNA strand scission and mitochondrial apoptosis. Inhibiting ERO1α expression can effectively counteract the geno- and cyto-toxic effects induced by arsenite.

Summary: IR isoforms exhibit different effects on cell proliferation and survival. While both IR-A and IR-B can inhibit cell proliferation when unbound to insulin, IR-B is more effective in reducing resistance to DNA damage. In the presence of insulin, IR-A provides a selective growth advantage over IR-B, particularly at high concentrations. Insulin-bound IR-A, but not IR-B, can protect cells from cytotoxicity induced by DNA damage.

Summary: Recife is ranked as the 16th most vulnerable city to climate change and has air pollutant levels exceeding the new limits proposed by the WHO. This study evaluates the health and economic benefits of reducing PM10 and PM2.5 concentrations to the new WHO limits, and simulates the behavior of these pollutants under increased temperatures using machine learning. The results show that meeting the new limits could prevent deaths and hospital admissions, improve life expectancy, while the temperature increase is predicted to worsen air pollution and health outcomes. Mitigation and pollution control policies are crucial for meeting the WHO air quality standards and achieving health benefits.

Summary: This study investigated the levels of air pollutants and the weekend effect before and after the COVID-19 pandemic in four cities in Brazil. It found a positive weekend effect for almost all air pollutants in these cities, with a relationship between the weekend effect and the restriction measures adopted. In scenarios with less restrictive policies, a negative weekend effect was observed, while more stringent measures resulted in higher intensities of positive weekend effect. These findings provide insights for responsible authorities in developing strategies and policies for air quality control.

Summary: The study aimed to investigate ethnic/racial disparities in COVID-19 mortality in Brazilian federative units and their respective capitals in 2020. The mortality rate of COVID-19 by ethnicity in Brazilian states was higher among people with brown skin color, followed by indigenous and black individuals. Only in one state, in the Federal District and in the federal capital, age-standardized mortality rates were higher among white individuals. There is a high percentage of deaths from COVID-19 higher than expected among non-white individuals, especially in south-central states and capitals of the country.

Summary: Small wild mammals, such as deer mice, have been used to measure the damage caused by exposure to oil-contaminated soil. However, there is currently no research on the toxic effects of crude oil using oxidative damage biomarkers in the wild rodent Calomys laucha (Vesper mouse). This study aimed to evaluate the effects of acute exposure to different concentrations of crude oil-contaminated soil on C. laucha using oxidative stress biomarkers. The results showed that acute exposure to oil-contaminated soil caused oxidative damage in C. laucha, indicating that these small mammals may be susceptible to the impacts of such contamination in their habitat, posing a threat to their survival.

Summary: Nowadays, the application of carbon-based materials in the development of chemically modified sensors is gaining attention due to their ability to generate methods with high sensitivity, stability, conductivity, accuracy, and low cost. As a result, these sensors have been used in environmental monitoring in an eco-friendly, sensitive, fast, efficient, inexpensive, and robust way. In this review, we first described carbon-based materials and their derivatives, followed by an overview of the manufacturing of chemically modified carbon-based sensors and their applications in environmental analytical chemistry for the determination of inorganic and organic compounds. Future perspectives on trends in the application of carbon-based materials for sensor modifications are also discussed.

Summary: The objective of this study was to investigate the influence of beta-carotene nanoemulsions on technological parameters and product stability in yogurt and gelato-type ice cream. The results showed that the addition of nanoemulsions increased the gelato yield and the syneresis index in yogurt, while reducing parameters such as firmness, consistency, cohesiveness, and viscosity index. The nanoemulsions also protected the carotenoid during storage, resulting in minimal color variation.

Summary: Burns damage the skin and its appendages, providing a favorable environment for bacterial infections. Due to the limitations and costs of current treatments, finding more efficient alternatives for burns is necessary. This study developed curcumin nanoemulsion-impregnated dressings using nanotechnology, which demonstrated stability and controlled release of curcumin. The evaluation showed that cationized dressings released curcumin faster, while non-cationized dressings promoted a more constant release.

Summary: This study evaluated the functional profile of soil microbiota and the gut microbiota of earthworms in ceftriaxone-contaminated soil using Biolog EcoPlate. The results showed that different concentrations of the antibiotic did not significantly affect the evaluated parameters. The functional profile of soil microbiota was similar with and without earthworms, but differed from the profile of earthworms' gut microbiota.

Summary: This study evaluated the weekend effect of air pollutants in Recife, a tropical Brazilian metropolis, during a 2-year period of monitoring, including the post-COVID-19 restrictions period. The results showed no weekend effect in both annual contexts, suggesting minimal impact. However, seasonal variations were observed in the dynamics of air pollutants, which were likely influenced by factors other than meteorological parameters. The study also found an impact of the end of COVID-19 restrictions on the weekend effect in the first year, and a significant correlation between SO2, NO2, and O-3 levels, indicating a shared source for these pollutants. The findings aim to assist in the development of air pollution control policies.
