Structure and functional genes associated with carbon, nitrogen, phosphorus, and sulfur cycling processes in periphyton: A comparison between natural and artificial rivers

open access: yesRiver, EarlyView.
Network analysis of functional genes among prokaryotes, and eukaryotes in natural and artificial rivers. Abstract Periphyton in aquatic ecosystems plays vital roles in the elemental cycle process and is vulnerable to anthropogenic interference. However, few studies have explored the elemental cycles of carbon (C), nitrogen (N), phosphorus (P), and ...

Thermosensitive Nanostructured Coacervates Developed by Mixing ABA‐ and AB‐Block Copolymers and Their Unique Sustained Release of Nano‐Micelles in a Regulated Manner

open access: yesSmall, EarlyView.
Polyion complex micelles composed of blends of ABA and AB block copolymers can form coacervates with a hexagonally packed cylinder nanostructure after heating. The resulting coacervates can release the micelles under physiological conditions in a zero‐order kinetics, possessing cargo proteins.

Disc‐Toroid Hybrid Lipid Nanoparticles for Efficient Drug Encapsulation and Subcutaneous Delivery

open access: yesSmall, EarlyView.
This study demonstrates sub‐50 nm solid‐lipid nanoparticles with long‐term stability, high drug loading, and strong tissue compatibility. Disc‐toroid morphology is confirmed and may play a role in cellular interactions, while low cytotoxicity and minimal systemic permeation confirm depot‐like behavior. These nanoparticles represent a versatile platform

The Multifaceted Role of Rad9 in the DNA Damage Response of Saccharomyces cerevisiae

open access: yesYeast, EarlyView.
ABSTRACT To maintain the integrity of the genome, cells have evolved a complex signalling system, termed the DNA damage response (DDR), which detects DNA damage and promotes DNA repair. To date, over 600 proteins have been identified that play an integral role in the DDR. RAD9, encoding a DDR mediator protein, was the prototypical DNA damage checkpoint

Polyamide Acid–Based Surface Modification of Poly(p‐Phenylene Benzobisoxazole) Fibres Reinforcing Syntactic Foam for Using Them as High‐Performance Insulating Core Material

open access: yesHigh Voltage, EarlyView.
ABSTRACT The insulating core is an important part of pillar composite insulators used in power transmission systems. Traditional insulating core materials suffer from various problems that can threaten the reliability of insulated equipment. Syntactic foam (SF) exhibits excellent properties, such as a low density, water penetration resistance and high ...

Occupational Sun Exposure and Melanoma Development: A Review of the Evidence

open access: yesAustralasian Journal of Dermatology, EarlyView.
ABSTRACT Cutaneous melanomas arise through a number of causal pathways, all of which involve exposure to sunshine or artificial ultraviolet (UV) radiation to some extent. Their initiation also depends on host factors that determine susceptibility to melanoma, and whether the UV exposure is intermittent or chronic.
