High-performance microwave absorption by optimizing hydrothermal synthesis of BaFeO@MnO core-shell composites.

Stealth technology advances in radar-absorbing materials (RAMs) continue to grow rapidly. Barium hexaferrite is the best candidate for RAMs applications. Manganese dioxide (MnO) is a transition metal with high dielectric loss and can be used as a booster for changing polarization and reducing reflection loss.

The combination of nutrition education at school and home visits to improve adolescents' nutritional literacy and diet quality in food-insecure households in post-disaster area (De-Nulit study): A study protocol of cluster randomized controlled trial (CRCT).

Nutrition education is selected as a method which often used to change eating behaviour, yet, the effectiveness of this method in adolescents who live in household with food insecurity status is rarely investigated. The purpose of this study was to assess the impact of a combination of nutritional education held at school and home visits for increasing the nutritional literacy and its effect on the quality of adolescent diet, so that the result can be used as a strategy to improve nutritional literacy dan diet quality in those adolescents who live in food-insecure households in post-disaster areas. The De-Nulit Study is a Cluster Randomized Controlled Trial (CRCT) with an intervention from a combination of nutritional education given at school and home visits conducted for three months for adolescents who live in food-insecure households with ages ranging from 15 to 17 years old.

Emerging challenges to prisoners vaccination of covid-19: Historical, legal and humanitarian view.

This research aims to present a legal history of the prisoners' treatment in global crises along with presenting an overview of prisoners' treatment during Covid-19 in view of International Humanitarian Laws. Using the formative research method with a conceptual approach and statute approach, data was gathered from various legal documents related to prisoners' health laws linked to legal purpose theories. This study further explains the need to treat old age prisoners on a priority basis and to what extent international health organizations are making efforts to establish criteria to vaccinate this societal segment.

Optimization of Ultrasonic-Assisted Extraction (UAE) Method Using Natural Deep Eutectic Solvent (NADES) to Increase Curcuminoid Yield from L., , and Val.

This study aims to optimize ultrasonic-assisted natural deep eutectic solvents (NADES) based extraction from . Choline chloride-lactic acid (CCLA-HO = 1:1, b/v) was used to investigate the impact of various process parameters such as solvent's water content, solid loading, temperature, and extraction time. The optimal yield of 79.

Antioxidant properties of the methanolic extract of avocado fruit peel ( Mill.) from Indonesia.

This study analyzed the antioxidant activity and the phytochemical substances in avocado fruit peel extracted with methanol. In this study, antioxidant activity was determined by IC based on the regression value of DPPH free radicals' inhibition. Phytochemical content was measured qualitatively concerning the total content of phenols, flavonoids, tannins, saponins, and alkaloids.

Antioxidant and antidiabetic compounds identification in several Indonesian underutilized Zingiberaceae spices using SPME-GC/MS-based volatilomics and methods.

This study aimed to identify compounds in 12 minor Zingiberaceae spices grown in Indonesia linked with in vitro α-glucosidase inhibitor and antioxidant (DPPH, FRAP, CUPRAC) activities using SPME-GC/MS volatilomics. The results illustrated that Val., (Burm.

α-glucosidase inhibitors from Syzygium polyanthum (Wight) Walp leaves as revealed by metabolomics and in silico approaches.

Ethnopharmacological Relevance: Syzygium polyanthum (Wight) Walp leaves are traditionally used to cure diabetes in many regions of Indonesia. Traditional use involves boiling the leaves until the water is reduced to half volume, and then the decoction is taken 1-2 times daily. Despite several studies reporting the antidiabetic activity of this plant, bioactive compounds have not been well identified.

Effect of premature rupture of membranes on preterm labor: a case-control study in Cilegon, Indonesia.

Objectives: The global prevalence of preterm labor is approximately 11.1% of live births. However, preterm labor contributes to 75-80% of neonatal morbidity and mortality.

Giant intrapulmonary malignant peripheral nerve sheath tumour.

Pulmonary malignant peripheral nerve sheath tumours (MPNSTs) are extremely rare soft tissue sarcomas that develop from the cell constituting the nerve sheaths, approximately 5-10% of all soft tissue sarcomas. We present a rare case of primary lung MPNST in an adult female non-smoker patient, in whom surgical thoracotomy approach has obtained a good control of the disease. Low-grade MPNST was established from excisional biopsy followed by immunohistochemistry.

Production of a polyclonal antibody against acrylamide for immunochromatographic detection of acrylamide using strip tests.

Objective: To produce, purify, and characterize a polyclonal antibody against acrylamide (anti-AA) for an application to immunochromatographic strip tests for AA.

Materials And Methods: Polyclonal anti-AA was prepared by injecting N-acryloxysuccinimideconjugated bovine serum albumin hapten-antigen into New Zealand white rabbits. The antibody was purified using protein A, characterized using sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) and conjugated with gold nanoparticles (AuNP).

Surfactant- and Binder-Free Hierarchical Platinum Nanoarrays Directly Grown onto a Carbon Felt Electrode for Efficient Electrocatalysis.

The future of fuel cells that convert chemical energy to electricity relies mostly on the efficiency of oxygen reduction reaction (ORR) due to its sluggish kinetics. By effectively bypassing the use of organic surfactants, the postsynthesis steps for immobilization onto electrodes, catalytic ink preparation using binders, and the common problem of nanoparticles (NPs) detachment from the supports involved in traditional methodologies, we demonstrate a versatile electrodeposition method for growing anisotropic microstructures directly onto a three-dimensional (3D) carbon felt electrode, using platinum NPs as the elementary building blocks. The as-synthesized materials were extensively characterized by integrating methods of physical (thermogravimetric analysis, X-ray diffraction, scanning electron microscopy, inductively coupled plasma, and X-ray photoelectron spectroscopy) and electroanalytical (voltammetry, electrochemical impedance spectrometry) chemistry to examine the intricate relationship of material-to-performance and select the best-performing electrocatalyst to be applied in the model reaction of ORR for its practical integration into a microbial fuel cell (MFC).
