Predictive action of oncomiR in suppressing TP53 signaling pathway in hypoxia-conditioned colon cancer cell line HCT-116.

Hypoxia-induced heterogeneity in colorectal cancer (CRC) significantly impacts patient survival by promoting chemoresistance. These conditions alter the regulation of miRNAs, key regulators of crucial processes like proliferation, apoptosis, and invasion, leading to tumor progression. Despite their promising potential as diagnostic and therapeutic targets, the underlying mechanisms by which miRNAs influence hypoxia-mediated tumorigenesis remain largely unexplored.

This research improves the strength of plastic using avocado seed starch and PLA. The effect of blending avocado seed starch and PLA was optimized using the RSM approach by using two variables: water absorption and biodegradability. Mixing them using RSM gave the best result: 1.

Insufficient criminal justice system response to the severity of domestic violence during the pandemic in Indonesia.

Domestic violence increased dramatically in Indonesia during the COVID-19 pandemic compared to the previous pandemic. This article analyses how Indonesia's criminal justice system responded to domestic violence during the pandemic. This article used secondary data gathered from various online resources and legal publications.

BMI and explicit-implicit cues on food choice: The fake food buffet in the United Kingdom and Indonesia.

We examined whether people with high BMI sampled from two different countries were more susceptible to behavioural change via an implicit, rather than explicit, intervention. We measured BMI and used three types of cue interventions (implicit vs explicit healthy lifestyle cue vs neutral cue) to examine their impact on our participants' food choice using the Fake Food Buffet. Healthiness of the meal chosen was measured by the percentage of healthy food items in the meal.

New model of sports tourism with sustainable tourism development to increase tourist arrivals in Central Aceh Regency, Indonesia.

Introduction: This study explores the development and implementation of a new sports tourism product called "Run H2O Ride" as a strategy for sustainable tourism in Indonesia.

Methods: The research employs a research and development (R&D) methodology, focusing on identifying potential issues, conducting literature reviews, designing the product, validating the design, and undergoing product development. A combination of discussion group forums (FGD) and expert judgment decisions was used to design the new sport tourism model.

Coprecipitation and hydrothermal synthesis of CaO from dolomite in the presence of extract for biodiesel production: catalysts characterization and optimization.

High-purity CaO cubic crystallites extracted from limestone exhibited excellent activity as base catalysts for waste cooking oil (WCO) conversion into biodiesel. Saponin from extract acted as a surfactant in CaO extraction and transformation into well-defined cubic microcrystallites. The application of saponin from extract as a surfactant for CaO production results in a high level of CaO purity and particle size reduction compared to directly calcined limestone (CaO-MgO).

extract inhibits migration by reducing MMP-9 and Rac-1 expression in highly metastatic breast cancer cells.

Background And Purpose: Highly metastatic breast cancer is a population of cancer cells that has metastasized to other organs in the body leading to apoptosis resistance. It was reported that MDAMB-231 cells contain lower levels of reactive oxygen species associated with metastatic capability. (CL) possesses cytotoxic effects in several cancer cells including metastatic breast cancer cells.

reduces the stemness of breast cancer stem cells involving the elevation of intracellular reactive oxygen species.

Background And Purpose: Breast cancer stem cells (BCSCs) as a kind of tumor cells are able to regenerate themselves, leading to apoptosis resistance and cancer relapse. It was reported that BCSCs contain lower levels of reactive oxygen species (ROS) associated with stemness capability. has been proposed for its chemopreventive potency against several cancer cells.

Reflecting on Indonesia's young academy movement.

In the past three decades, there has been a rise in young academy movements in the Global North and South. Such movements, in at least Germany and the Netherlands, have been shown to be quite effective in connecting scientific work with society. Likewise, these movements share a common goal of developing interdisciplinary collaboration among young scientists, which contributes to the growth of a nation's-but also global-scientific endeavors.

Artificial Intelligence Approach for Severe Dengue Early Warning System.

Dengue fever is a viral infectious disease transmitted through mosquito bites, and has symptoms ranging from mild flu-like symptoms to deadly complications. Dengue fever is one of the global burden diseases which annually have 50-100 million cases with 500,000 cases of severe dengue fever, of which 22,000 deaths occur mostly in children. Despite the discovery of vaccines, vector control is still the main approach for prevention efforts.
