Peptide‐directed nanovehicles enabling tumor‐selective ROS amplification and antitumor immunity

VIEW, EarlyView.
Cancer cells are vulnerable to oxidative stress, yet exploit immune tolerance to escape destruction. In contrast, their metabolic profile is markedly altered to support rapid proliferation, accompanied by elevated production of reactive oxygen species (ROS).

High‐Altitude Adaptation of Frogs (Case Study: Nanorana parkeri): From Physiological Phenotypes to AltitudeOmics

Integrative Zoology, EarlyView.
High altitudes are challenging for the animals that inhabit these environments. The Xizang plateau frog (Nanorana parkeri) survives in high‐altitude environments through a synergistic strategy of metabolic remodeling and protein expression adjustment to optimize energy efficiency and enhance cellular protection.

A 3D Bioprinted Platform That Maintains the Functional Integrity of Primary AML Cells

Cell Proliferation, EarlyView.
This study presents a 3D bioprinted platform using gelatin‐hyaluronic acid hydrogels to enhance primary AML cell survival and proliferation while preserving stem‐like properties in vitro. By recapitulating in vivo‐like metabolic activity and drug resistance, this system offers a robust tool for preclinical drug screening and personalised therapy ...

Novel Histopathologic Features of Diffuse Blue‐Gray Hyperpigmentation Associated With Kratom Use: A Case Report and Literature Review

Journal of Cutaneous Pathology, EarlyView.
ABSTRACT Background Drug‐induced hyperpigmentation accounts for 10%–20% of acquired pigmentary disorders and can be misdiagnosed for other causes such as melasma, post inflammatory changes, or heavy metal deposition. Kratom (Mitragyna speciosa), a Southeast Asian plant with an opioid‐like profile, has been increasingly used in the United States for ...

Unraveling the active site cover of coproheme decarboxylase from Listeria monocytogenes

The FEBS Journal, EarlyView.
During heme biosynthesis in Gram‐positive bacteria, coproheme decarboxylase (ChdC) catalyzes the conversion of four‐propionate substrate coproheme to the two propionate product heme b. Its active site is universally covered by a flexible linking loop. This study identifies an important histidine residue, which stabilizes the loop in a ChdC homolog.

Molecular dynamics simulations and fluorescence spectroscopy suggest reduced tryptophan‐to‐heme energy transfer facilitates lignin degradation in ClassII peroxidases

The FEBS Journal, EarlyView.
In lignin peroxidase and versatile peroxidase, low FRET from buried Trp to heme promotes long‐range electron transfer (LRET) from substrate to heme. This efficient electron flow is facilitated by reduced FRET competition. This mechanism likely evolved to enable the effective degradation of bulky, high‐redox‐potential lignin that cannot reach the enzyme'

Effects of Regular Dual‐Light Antibacterial Photodynamic Therapy on Oral Health in Assisted Living Residents—A Randomized Controlled Trial

Gerodontology, EarlyView.
ABSTRACT Objective The objective of this study is to investigate the effect of dual‐light antimicrobial photodynamic therapy (aPDT) on oral health among older people living in assisted living facilities (ALF), comparing it to conventional oral self‐care guidance.

Scalp Microbiome Alterations in Androgenetic Alopecia: Patterns and Emerging Mechanistic Insights

International Journal of Dermatology, EarlyView.
Summary of the microbiome‐lipid‐microinflammation axis in androgenetic alopecia (AGA). Altered sebaceous gland activity, shifts in microbial abundance on the scalp and hair follicle, and follicular microinflammation interact bidirectionally, each reinforcing the others.
