Isolation, structural re-elucidation of two active prenylated flavonoids from Morus alba L. twigs responsible for anti-inflammatory effects: an in vitro and in silico approach

Abstract Ethnobotanical relevance Morus alba L. has been reported to exhibit various pharmacological effects, including antipyretic, hepatoprotective, nephroprotective, antihypertensive, and anti-inflammatory activities, as well as benefits for sore throat relief and eyesight improvement in traditional medicine. Aim of the study This study investigates the anti-inflammatory potential of two prenylated flavonoids isolated from the twigs of Morus...

Characterizing particulate-bound mercury (PBM2.5) in multiple sites of Southeast Asia megacity: Insights from Hg relationships with carbonaceous components

Abstract Fine particulate-bound mercury (PBM2.5) is being recognized as a public health and environmental issue owing to its high capacity to bioaccumulate and long-range transport. This study investigates PBM2.5 at two urban sites Nguyen Van Cu (NVC) and Linh Trung (LT) and one rural site Can Gio (CG) in Ho Chi Minh City (HCMC) to assess...

A Hybrid Dynamic Gold Code Architecture Resilient to Side-Channel Analysis Attacks in 180-nm CMOS

Abstract This study presents a hardware countermeasure that integrates two distinct types of random number generators. Recently, several effective time-based countermeasures against side-channel analysis (SCA) have relied on FPGA-specific primitives, such as Xilinx Digital Clock Managers (DCM) and Mixed-Mode Clock Managers (MMCM). However, these solutions lack portability to ASIC platforms. To address this, we propose...

Prototethyan Tam Ky-Phuoc Son ocean subduction-rollback dynamics: Insights from Early Paleozoic

Abstract The Tam Ky–Phuoc Son Ocean in Central Vietnam, a southern branch of the Prototethyan Ocean, holds critical evidence of Early Paleozoic subduction processes in Southeast Asia. However, the polarity and tectonic evolution of its subduction system remain controversial. Here we present new petrographic observations, zircon U-Pb geochronology, in situ zircon Hf isotopes and whole-rock...

Establishment of a BALB/c Mouse Model for Photoaged Skin: Insights into UV-Induced Dermatological Changes

Abstract Background: Photoaging, primarily induced by prolonged ultraviolet (UV) radiation exposure, significantly alters skin structure and function, necessitating models for deeper understanding and intervention development. This study aims to establish a BALB/c mouse model for investigating photoaging, leveraging their haired skin and genetic consistency. Materials and methods: Six-week-old female BALB/c mice were subjected to repeated exposure to...

Structural optimization of stress-bearing structures of nearly incompressible problems under design-dependent pressure loads

Abstract An efficient and innovative method is presented for the stress-related structural topology optimization (TO) in coupled mechanical-pressure systems by leveraging flexible polygonal meshes. With a polytopal composite finite element approach, the volumetric locking in nearly incompressible materials is reduced. A fluid-flow-based model is built, in which a design-dependent pressure variable is introduced to capture...

Developing low-cost nanohybrid of CuO nanoflakes and graphene thin film for sustainable photodetector applications

Abstract In recent years, the development of low-cost and flexible optoelectronic devices with minimal chemical usage has attracted increasing attention for sustainable development. This study introduces our development of a flexible visible photodetector based on a nanohybrid of copper oxide nanoflakes (2D-CuO) and reduced graphene oxide thin film (rGO), using just five initial materials. Particularly,...

Hardwood Burning as a Dominant Source of Fine Particulate Matter from Biomass Burning in Ho Chi Minh City, Vietnam

Abstract While biomass burning (BB) significantly affects air quality in Southeast Asia, its contribution to PM2.5 in Ho Chi Minh City (HCMC), Vietnam’s most populous city, remains poorly understood. This study aimed to identify the major BB sources contributing to PM2.5 in urban HCMC, with particular attention to the potential underestimation caused by chemical degradation...

Dark photon dark matter constraints at the Taiwan Axion Search Experiment with Haloscope

Abstract The dark photon is a well motivated candidate for the dark matter that comprises most of the mass of our visible Universe, leading to worldwide experimental and observational efforts toward its discovery. A primary tool in this search is the cavity haloscope, which facilitates resonantly enhanced conversion to photons from both dark photons and...
