Our previous study highlighted the anticancer potential of sea hare hydrolysate (SHH), particularly its role in regulating macrophage polarization and inducing pyroptotic death in lung cancer cells through the inhibition of signal transducer and activator of transcription 3 (STAT3). These findings prompted us to investigate additional features of immune-oncology (I-O) agents or adjuvants, such as programmed cell death protein 1 (PD-1)/programmed death ligand 1 (PD-L1) inhibition and their association with rheumatoid arthritis (RA) risk, to explore the potential of SHH as an I-O agent or adjuvant. In this study, we investigated the effects of SHH on PD-L1 levels in various cancer cell types and assessed its effectiveness in treating RA, a common side effect of I-O agents.

The effectiveness of strengthening social protection and security has proven to alleviate poverty in rural communities in the Garut Regency area, West Java Province, Indonesia, due in particular to excellent multi-sectoral cooperation. The social protection and security programs that the Indonesian Government provides are mainly targeted at the poor, as recorded in the social welfare data (DTKS). Poor people who are not registered with the DTKS cannot obtain social assistance programs.

Calliandra calothyrsus and Gliricidia sepium ash characteristics as co-firing fuel to high-sulfur and -iron coal were investigated through theoretical prediction, FactSage modelling, and combustion experiment in drop tube furnace. The results show that the addition of Calliandra and Gliricidia were able to mitigate the slagging risk according to theoretical prediction and FactSage modelling. Slag formations were predicted to occur at higher combustion temperature compared to coal which was reflected in higher ash fusion temperature.

Ulcer disorders including the oral mucosa, large intestine, and stomach mucosa, cause significant global health burdens. Conventional treatments such as non-steroid anti-inflammatory drugs (NSAIDs), proton pump inhibitors (PPIs), histamine H receptor antagonists (HRAs), and cytoprotective agents have drawbacks like mucosal injury, diminish gastric acid secretion, and interact with concurrent medications. Therefore, alternative therapeutic approaches are needed to tackle this health concern.

Calliandra calothyrsus and Gliricidia sepium are developed as wood energy forest plantations in degraded land. They have good survivability, are fast to be harvested, and have good calorific value to be utilized as biomass fuel. This study aims to investigate their combustion characteristics by thermogravimetric analysis and their ash-related issues by combustion experiments in drop tube furnace and ash observation.

While deepfake technology is still relatively new, concerns are increasing as they are getting harder to spot. The first question we need to ask is how good humans are at recognizing deepfakes - the realistic-looking videos or images that show people doing or saying things that they never actually did or said generated by an artificial intelligence-based technology. Research has shown that an individual's self-efficacy correlates with their ability to detect deepfakes.

Article Synopsis
  • Splenomegaly, or spleen enlargement, is commonly found in patients with malarial anemia caused by Plasmodium falciparum or P. vivax, but the reasons for this connection are not fully understood.
  • A study in Papua, Indonesia measured red blood cell (RBC) concentrations in the spleens of 37 patients, discovering that spleen size correlated positively with the amount of red-pulp and negatively with white-pulp, indicating a relationship between spleen composition and size.
  • The research revealed that retained RBCs, primarily uninfected, accounted for significant blood loss in P. falciparum infections, and this retention correlated negatively with hemoglobin levels and circulating RBC counts, highlighting the impact

Dog-mediated rabies is endemic in much of Indonesia, including Bali. Most dogs in Bali are free-roaming and often inaccessible for parenteral vaccination without special effort. Oral rabies vaccination (ORV) is considered a promising alternative to increase vaccination coverage in these dogs.

Severe malaria after splenectomy has been reported with infections with Plasmodium falciparum, Plasmodium knowlesi, and Plasmodium malariae, but is less well-characterized with Plasmodium vivax. We describe a case of severe P. vivax malaria with hypotension, prostration, and acute kidney injury occurring 2 months after splenectomy in Papua, Indonesia.

Anthropogenic is defined as one of the influencing factors of the climatic phenomenon, called Urban Heat Island (UHI), in which urban areas have higher air temperatures than their rural surroundings. Analyzing the impact of anthropogenic factors, such as vehicular traffic, has implications for the potential benefits of health monitoring systems; however, the spatiotemporal impact of anthropogenic factors, as well as vehicle mobility, has not been thoroughly investigated. This study incorporates vehicle mobility data by leveraging two different sensors; fixed station sensor instruments designed to integrate with the Internet of Things (IoT), and the camera of an area traffic control system (ATCS) that uses CCTV visualization with object detection.

Background: miRNA-21, one of breast cancer (BC) predictive markers, is now gaining cardinal attention from researchers worldwide to evaluate BC patients' survival rate. However, cancer staging, hormonal status, and other BC markers still have to be discussed. We aim to determine the relationship between miRNA-21 and associating factors such as BC staging, other tumor markers, and hormonal status to predict the 2-year survival rate of BC patients.

Article Synopsis
  • Asymptomatic infections of P. falciparum malaria in adults may hinder clinical immunity rather than support it, serving as a reservoir for the parasite and aiding its transmission.
  • Researchers used a systems approach involving antibody responses and cell profiling to study the immune responses in individuals with symptomatic and asymptomatic malaria, linking certain immune cell profiles to a lower risk of clinical malaria.
  • Findings indicate that while some immune responses exist, asymptomatic infections also promote immunosuppressive mechanisms that could undermine effective immune control and vaccine responsiveness against malaria.

Background: In the field of moral psychology, researchers have strived to understand the complex dynamics of corruption psychology. This study contributes to this area by presenting a theoretical model for sequential behavior, placing counterfeit behavior (CB) as a predictor and corruption tendencies (proneness to moral emotions, ie, guilt and shame/GASP) as the criterion. In addition, two bridging variables are assigned, ie, inauthenticity/counterfeit self (CS) and moral disengagement (MD).

This paper presents the chemical and mechanical properties of Corypha utan leaf fiber (CULF) subjected to different chemical treatments for reinforced composite materials. Natural fibers are currently considered as an alternative constituent for composite reinforcement due to their friendly environment character. The CULF were chemically treated during a pre-fabrication process using NaOH, and 3-(Trimethoxysilyl) propyl methacrylate was introduced at three different concentrations of 0%, 5%, and 10%, respectively.

Cellulose nanofibers (CNFs), chitosan, and silver nanoparticles (AgNPs) are widely used to enhance the active functions and antibacterial properties of wound dressings. This study was conducted to prepare CNF/AgNP-chitosan using a straight incorporation method and to assess its antimicrobial activity. CNFs were isolated from oil palm empty fruit bunches (OPEFBs) using the pulping method and acid hydrolysis.

Article Synopsis
  • The study explores the complex role of IFN-γ in malaria, particularly its influence on T follicular helper cells and memory B cells, which are crucial for effective antibody responses and immunity.
  • Through single-cell mass cytometry, distinct populations of CD4+ T cells with the T-bet factor were identified, showing varying risks for Plasmodium vivax malaria outcomes, indicating that inflammation can sometimes be beneficial.
  • Additionally, specific types of memory B cells and T cell subsets were linked to reduced risk of symptomatic malaria, while others contributed to protection against asymptomatic infections, highlighting the need for both antibody and cell-mediated immunity in managing malaria.
