DNA‐Enzyme Hybrid Nanostructures: Functional Materials to Modulate Enzymatic Activity

open access: yesSmall, EarlyView.
DNA–enzyme hybrid nanostructures enable precise spatial and stoichiometric control over enzyme organization, offering a powerful platform to modulate catalytic activity. This review critically evaluates key mechanistic hypotheses, including proximity effects, microenvironment changes, confinement, and stabilization, as well as highlighting ...

New drugs and vaccines for drug-resistant Mycobacterium tuberculosis infections [PDF]

open access: yes, 2008
Tuberculosis remains the most common cause of death due to a single infective organism. Despite the availability of a vaccine and chemotherapeutic options, the global disease burden remains relatively unaffected.

Stimuli‐responsive nanostructured hydrogen sulfide donors for enhanced cancer treatments

open access: yesSmart Molecules, EarlyView.
Three typical kinds of stimuli‐responsive nanostructured hydrogen sulfide (H2S) donors are reviewed. The nanostructures ensure precise delivery of H2S to the lesion site and regulate the release behavior. The H2S‐based gas therapy has been used to synergize with other cancer treatment modalities, achieving enhanced efficacy while reducing side effects.

In vitro comparison of Aldicarb oxidation in various food producing animal species

open access: yes, 1995
Aldicarb (ALD) metabolism was studied in vitro using hepatic microsomes from chickens, rabbits, sheep and pigs. The microsomal activities of mono-ooxygenase enzymes (flavin-containing and cytochrome P-450-dependent mixed function oxygenases) were ...

Genetic Analysis of Stress Responses in Soil Bacteria for Enhanced Bioremediation of Mixed Contaminants [PDF]

open access: yes, 2000
In order to realize the full potential of bioremediation, an understanding of microbial community and individual bacterial responses to the stresses encountered at contaminated sites is needed.

Chrysin Mitigates Acetamiprid‐Induced Testicular Injury in Mice via Suppression of Endoplasmic Reticulum Stress and Inflammation

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT Acetamiprid (ACP) is a neonicotinoid pesticide that is extensively utilized for the management of insect populations, but its toxic effects on the male reproductive system have become a source of concern. Chrysin (CHR) is a natural flavone found in many plants and bee products, including honey and propolis.

Response of Fecal Bacteria and Fungi to Tannin‐Rich Diets in Sika Deer (Cervus nippon): Evidence from Both Feeding Experiments and Field Investigations

open access: yesIntegrative Zoology, EarlyView.
Feeding with tannin‐rich diets altered the fecal microbial composition and increased the relative abundance of tannin‐degrading microbes. We hypothesize that fecal bacteria and fungi may play important roles in helping herbivores adapt to tannin‐rich diets but respond to different tannin concentrations varies.
