Characteristics of naturally woven Waru bark fiber for eco-friendly composite reinforcement.

The aim of this study was to investigate the potential of Waru bark fiber (WBF) as a reinforcement material for composite. To achieve this aim, WBF was extracted using a conventional process, ensuring purity, and then characterized for physical, mechanical, chemical, and thermal properties. Microstructure analysis was performed using Scanning Electron Microscope (SEM) to show uniform and exceptional fiber sheets with naturally woven fiber shapes.

Analysis of the Relationship between Atherosclerosis Cardiovascular Disease Risk Profile and Occupational Profile to the WHO Cardiovascular Risk Chart 2019 for South-East Asia in Oil and Gas Industry.

The World Health Organization (WHO) has launched a new 10-year cardiovascular risk prediction recommendation known as the WHO Cardiovascular Risk Chart 2019 (WHO CRC). However, there is currently no assessment available regarding the relationship between ASCVD classic and occupational profiles to WHO CRC, specifically in occupational settings and in the context of the Indonesian Heart Association's (IHA) adjusted version of the WHO CRC for South-East Asia (WHO CRC-INA). This study aims to fill this gap by examining the relationship between classic (Atherosclerosis Cardiovascular Disease) ASCVD and occupational profiles within the oil and gas industry, specifically the WHO CRC-INA.

Analyzing Molecular Traits of H9N2 Avian Influenza Virus Isolated from a Same Poultry Farm in West Java Province, Indonesia, in 2017 and 2023.

Background: Indonesia is one of the countries that is endemic to avian influenza virus subtype H9N2. This study aims to compare the molecular characteristics of avian influenza virus (AIV) subtype H9N2 from West Java.

Methods: Specific pathogen-free (SPF) embryonated chicken eggs were used to inoculate samples.

Dual anti-inflammatory activities of COX-2/5-LOX driven by kratom alkaloid extracts in lipopolysaccharide-induced RAW 264.7 cells.

Cyclooxygenase (COX) and lipoxygenase (LOX) enzymes play a pivotal role in producing pro-inflammatory eicosanoids, including prostaglandins (PGs) and leukotrienes (LTs), in the inflammation process. Mitragynine is a primary alkaloid contained in the kratom's leaves and has been reported to show anti-inflammatory activity by suppressing COX-2 mRNA translation to lowering PGs synthesis. In this study, the Kratom's alkaloid extract containing ~ 46% mitragynine was found to exhibit dual inhibition activity towards COX-2/5-LOX enzymes at concentrations below 25 ppm in the LPS-induced RAW 264.

Occipital Vascularized Bone Graft for Reconstruction of a C3-C7 Defect.

The number of spinal reconstruction cases is growing, as are the accompanying complications. Wound complications after spinal reconstruction can be fatal and can affect up to 19% of patients undergoing major spine surgery. The discipline of spinoplastic surgery is characterized by the use of vascularized bone grafts to reconstruct spinal defects, which provide better results compared with nonvascularized and allogenic equivalents, owing to their superior blood supply.
