RESUMO
The emergence of cultivated meat provides a sustainable and ethical alternative to traditional animal agriculture, highlighting its increasing importance in the food industry. Biomaterial scaffolds are critical components in cultivated meat production for enabling cell adhesion, proliferation, differentiation, and orientation. While there's extensive research on scaffolding biomaterials, applying them to cultivated meat production poses distinct challenges, with each material offering its own set of advantages and disadvantages. This review summarizes the most recent scaffolding biomaterials used in the last five years for cell-cultured meat, detailing their respective advantages and disadvantages. We suggest future research directions and provide recommendations for scaffolds that support scalable, cost-effective, and safe high-quality meat production. Additionally, we highlight commercial challenges cultivated meat faces, encompassing bioreactor design, cell culture mediums, and regulatory and food safety issues. In summary, this review provides a comprehensive guide and valuable insights for researchers and companies in the field of cultivated meat production.

Cancer is a complex disease characterized by the uncontrolled growth of abnormal cells, leading to the formation of tumours. STK17B, a member of the DAPK family, has been implicated in various cancers and is considered a potential therapeutic target. However, no drug in the market has been approved for the treatment of STK17 B-associated cancer disease. This research aimed to identify direct inhibitors of STK17B using computational techniques. Ligand-based virtual screening and molecular docking were performed, resulting in the selection of three lead compounds (CID_135698391, CID_135453100, CID_136599608) with superior binding affinities compared to the reference compound dovitinib. While molecular docking simulation revealed specific interactions between the lead compounds and key amino acid residues at the binding pocket of STK17B, molecular dynamics simulations demonstrated that CID_135453100 and CID_136599608 exhibit stable conformations and comparable flexibility to dovitinib. However, CID_135698391 did not perform well using this metric as it displayed poor stability. Overall, small-molecule compounds CID_135453100 and CID_136599608 showed promising binding interactions and stability, suggesting their potential as direct inhibitors of STK17B. These findings could contribute to the exploration of novel therapeutic options targeting STK17B in cancer treatment.Communicated by Ramaswamy H. Sarma.
RESUMO
The regulation of the p53 tumor suppressor pathway is critically dependent on the activity of Murine Double Minute 2 (MDM2) and Murine Double Minute X (MDMX) proteins. In certain types of cancer cells, excessive amount of MDMX can poly-ubiquitinate p53, which can result in its degradation, leading to a subsequent reduction in the levels of this protein. Therefore, the design of small-molecule inhibitors targeting the MDMX-p53 interaction has emerged as a promising strategy for cancer therapy. In this study, we employed computational techniques including pharmacophore modeling and molecular docking to identify three potential small molecule inhibitors (CID_25094615, CID_137634453, and CID_25094344) of the MDMX-p53 interaction from a PubChem database. Molecular dynamics of 100000 ps were conducted to assess the stability of the MDMX-inhibitor complexes. Our results showed that all three compounds exhibit stable binding with MDMX, with significantly lower root mean square deviation (RMSD) and fluctuation (RMSF) values than the control ligand, indicating superior stability. Additionally, the three compounds exhibit stronger intermolecular hydrogen bond (HBOND) interactions compared to the control, suggesting stronger stability. Overall, our findings highlight the potential of these compounds as lead candidates for the development of novel anticancer agents that target the MDMX-p53 interaction.Communicated by Ramaswamy H.

RESUMO
BACKGROUND: Despite global interventions to prevent and control diarrhea, it still remains a public health problem leading to childhood morbidity and mortality majorly in developing countries. In Uganda, diarrhea is amongst the five leading causes of under-five mortality, contributing to more than 140,000 deaths every year and this accounts for 7.1% of all under-five mortalities in Uganda. Efforts to prevent and lower diarrheal diseases need to be informed by data on determinants of diarrhea. The study assessed factors associated with diarrheal diseases among children below five years in selected slum settlements in Entebbe municipality, Wakiso District, Uganda. METHODS: The study employed a cross-sectional study design covering 384 randomly selected households having children < 5 years old in the study area using quantitative research methods. Data was collected using close-ended questionnaires and diarrhea disease history was captured for the last month before the survey. Bivariate and multivariate logistic regression analyses were used to identify the risk factors associated with childhood diarrhea considering a 95% confidence level. RESULTS: The prevalence of Diarrhea disease in children among the selected slum settlements in Entebbe municipality was found to be at 62.4%. Access to water from a protected water source (deep well and borehole), presence of a vent in toilets, age, and child birth weight were found to be significantly associated with diarrheal diseases among children below five years in the selected slum settlements in Entebbe municipality. CONCLUSION: The prevalence of childhood diarrhea among children < 5 years of age in selected slums of Entebbe municipality was found high. Use of water from a protected source, presence of a vent in toilets, age, child birth and weight were identified as predictors of diarrhea occurrence. These findings imply that community health education is urgently needed for fighting childhood diarrhea in the study area to eliminate the predisposing factors to diarrhea.

This study examines the relationship between economic resources, psychosocial well-being, and educational preferences of AIDS-orphaned children in southern Uganda. We use baseline data from a sample of 1410 AIDS-orphaned children (defined as children who have lost one or both biological parents to AIDS) enrolled in the Bridges to the Future study, a National Institute of Child Health and Human Development (NICHD) funded study. Analyses from both bivariate and multiple regression analyses indicate the following: 1) despite the well-documented economic and psychosocial challenges AIDS-orphaned children face, many of these children have high educational plans and aspirations; 2) educational aspirations differ by orphanhood status (double orphan vs. single orphan); 3) regardless of orphanhood status, children report similar levels of psychosocial well-being; 4) high levels of family cohesion, positive perceptions of the future, school satisfaction, and lower levels of hopelessness (hopefulness) are associated with high educational aspirations; and 5) reported family economic resources at baseline, all seem to play a role in predicting children's educational preferences and psychosocial well-being. These findings suggest that the focus for care and support of orphaned children should not be limited to addressing their psychosocial needs. Addressing the economic needs of the households in which orphaned children live is equally important. Indeed, in the context of extreme poverty-in which most of the children represented in this study live-addressing structural factors, including poverty, may be a key driver in addressing their psychosocial functioning.
