Sources of HIV information and women's HIV knowledge in Southwest Sumba Indonesia: a cross-sectional study with mediation analysis.

Background: Despite multiple years of government HIV educational efforts, the growing trend of new cases among women in Indonesia runs parallel with their seemingly overall lack of comprehensive knowledge about HIV. A major prevention challenge for the Indonesian government lies in delivering HIV prevention education across the world's largest archipelago. This study investigates comprehensive HIV knowledge among reproductive-age women in Southwest Sumba, Indonesia, and the sources through which they report having learned about HIV along with potential mediators of the relationship between socioeconomic status (SES) and HIV knowledge.

Working with technical purity: simulation of red tattoo pigment metabolism by online-liquid chromatography-electrochemistry-mass spectrometry.

Tattooing is a popular form of body art that has evolved from ancient times into being part of modern society. The understanding of biotransformation processes of coloring tattoo pigments in human skin is limited although skin reactions to tattoos with unknown culprits occur. Electrochemistry coupled to mass spectrometry (EC-MS) has widely been used as a tool for a purely instrumental approach to simulating the enzymatic biotransformation of xenobiotics.

Assessment of wetland ecological restoration effect based on fuzzy analytic hierarchy process: a case study of Tianjin Qilihai Wetland.

Scientific evaluation of the effectiveness of ecological restoration could provide support for sustainable management and protection of wetlands. However, due to the multiple and difficult to quantify factors affecting wetlands, commonly used spatiotemporal evaluation methods were difficult to scientifically reflect the actual effectiveness of ecological restoration. This paper took Tianjin Qilihai Wetland, a representative wetland in northern China, as the research object.

Microbial volatile organic compounds measured in the air of a waste sorting plant and a university by thermal desorption-gas chromatography-tandem mass spectrometry.

In recyclable waste management facilities, several contaminants, mainly bioaerosols and microorganisms, can be released and cause potential adverse health effects. Given that microbial volatile organic compounds (mVOCs) are metabolites developed by molds and since they can be considered as potential biomarkers of mold exposure, their concentrations in ambient air were monitored at a recyclable waste sorting plant (WSP) and a university campus (UC) serving as control environment for comparison. A recently developed analytical method was used for the detection of 21 selected mVOCs in real conditions.

Degrowth as a plausible pathway for food systems transformation.

Food systems require urgent transformation towards social and ecological sustainability. Degrowth posits a radical pathway of transformation to reduce ecological impacts while increasing well-being and reducing inequality. Here we highlight that degrowth and food systems-albeit both linked to transformation-are not well integrated.

Demonstration of active neutron interrogation of special nuclear materials using a high-intensity short-pulse-laser-driven neutron source.

Detecting shielded special nuclear material, such as nuclear explosives, is a difficult challenge pursued by non-proliferation, anti-terrorism, and nuclear security programs worldwide. Interrogation with intense fast-neutron pulses is a promising method to characterize concealed nuclear material rapidly but is limited by suitable source availability and proven instrumentation. In this study we have pioneered a demonstration of such an interrogation method using a high-intensity, short-pulse, laser-driven neutron source that offers potential benefits compared to conventional neutron sources.

Design of anomalous reflecting metasurface for communication systems.

This paper presents a novel design approach for an anomalous reflector metasurface for communication systems operating at 8 GHz band. The main contribution of this work is the development of a general analytical method that accurately calculates the electromagnetic response of realistic metasurfaces with periodic impedance profiles. The modulated surface impedance is achieved by incorporating appropriately sized conductive patches on a grounded dielectric substrate.

Subfamily evolution analysis using nuclear and chloroplast data from the same reads.

The chloroplast (cp) genome is a widely used tool for exploring plant evolutionary relationships, yet its effectiveness in fully resolving these relationships remains uncertain. Integrating cp genome data with nuclear DNA information offers a more comprehensive view but often requires separate datasets. In response, we employed the same raw read sequencing data to construct cp genome-based trees and nuclear DNA phylogenetic trees using Read2Tree, a cost-efficient method for extracting conserved nuclear gene sequences from raw read data, focusing on the Aurantioideae subfamily, which includes Citrus and its relatives.

Therapy-induced senescent cancer cells contribute to cancer progression by promoting ribophorin 1-dependent PD-L1 upregulation.

Conventional chemotherapy- and radiotherapy-induced cancer senescence, which is characterized by poor proliferation, drug resistance, and senescence-associated secretory phenotype, has gained attention as contributing to cancer relapse and the development of an immunosuppressive tumor microenvironment. However, the association between cancer senescence and anti-tumor immunity is not fully understood. Here, we demonstrate that senescent cancer cells increase the level of PD-L1 by promoting its transcription and glycosylation.

Synaptoneurolipidomics: lipidomics in the study of synaptic function.

The brain is an exceptionally lipid-rich organ with a very complex lipid composition. Lipids are central in several neuronal processes, including membrane formation and fusion, myelin packing, and lipid-mediated signal transmission. Lipid diversity is associated with the evolution of higher cognitive abilities in primates, is affected by neuronal activity, and is instrumental for synaptic plasticity, illustrating that lipids are not static components of synaptic membranes.

Background: Low earnings are associated with household insecurity. Direct Support Professionals (DSPs) provide support for people with intellectual and developmental disabilities, typically for wages close to state minimums, and may experience insecurity.

Objective: The purpose of the study was to evaluate the prevalence of food and housing insecurity among DSPs.

Preliminary study of the upper limb with the use of ultrasound transmission imaging.

A biologically safe, noninvasive method for visualizing bone and soft tissue relationships has been developed recently. Termed the ultrasonic transmission imaging system, its advantages include visualization of soft tissues in real time while motion is underway. The image can be correlated to standard x-ray films, but since no ionizing radiation is involved, repeated risk-free visualization of extremities for either diagnostic assessment or biomechanical studies is permitted.
