Dual‐Functional Ingestible Passive Capsules for High‐Throughput Intestinal Sampling with Sealed Containment and Targeted Drug Delivery

open access: yesAdvanced Robotics Research, EarlyView.
To address challenges in high‐throughput intestinal sampling with sealed containment and target drug delivery, we developed a dual‐functional ingestible passive capsule with a dual‐triggered control system based on pH‐response and mechanical actuation.

Markedly different ATP requirements for rRNA synthesis and mtDNA light strand transcription versus mRNA synthesis in isolated human mitochondria [PDF]

open access: yes, 1987
In isolated mitochondria from HeLa cells, the ATP requirements for mitochondral DNA (mtDNA) transcription and RNA processing can be satisfied by either endogenous synthesis, mainly through oxidative- phosphorylation, or by exogenous supply.

Impairing the production of ribosomal RNA activates mammalian target of rapamycin complex 1 signalling and downstream translation factors [PDF]

open access: yes, 2014
Ribosome biogenesis is a key process for maintaining protein synthetic capacity in dividing or growing cells, and requires coordinated production of ribosomal proteins and ribosomal RNA (rRNA), including the processing of the latter.

3D‐Printed Macroporous Resin Anode in Microbial Fuel Cell‐Based Biosensors for Efficient Biodegradable Organic Carbon Monitoring

open access: yesAdvanced Sensor Research, EarlyView.
This study presents a 3D‐printed gyroid resin anode for microbial fuel cell biosensors. Compared with carbon felt, it enables either a broader dynamic range or higher sensitivity, depending on the operation mode. By improving real‐time monitoring of organic load, these biosensors support more efficient process control and contribute to the goal of ...

Bacterial Community Reconstruction Using A Single Sequencing Reaction [PDF]

open access: yes, 2010
Bacteria are the unseen majority on our planet, with millions of species and comprising most of the living protoplasm. While current methods enable in-depth study of a small number of communities, a simple tool for breadth studies of bacterial population

Self-reinoculation with fecal flora changes microbiota density and composition leading to an altered bile-acid profile in the mouse small intestine [PDF]

open access: yes, 2019
Background: The upper gastrointestinal tract plays a prominent role in human physiology as the primary site for enzymatic digestion and nutrient absorption, immune sampling, and drug uptake.

Excessive DNA Double‐Strand Breaks–Associated 3D Genome Reorganization Contributes to Neural Tube Defects with Folate Deficiency

open access: yesAdvanced Science, EarlyView.
Neural tube defects (NTDs) are among the most common congenital malformations. However, the underlying etiology and mechanism remain elusive. Here, the role of DNA double‐strand breaks (DSBs) in 3D genome organization within the NTDs with folate deficiency is reported.

rRNA operon improves species-level classification of bacteria and microbial community analysis compared to 16S rRNA

open access: yesMicrobiology Spectrum
Precise identification of species is fundamental in microbial genomics and is crucial for understanding the microbial communities. While the 16S rRNA gene, particularly its V3-V4 regions, has been extensively employed for microbial identification ...

Multiomics Analyses Reveal an Essential Role of Tryptophan in Treatment of csDMARDs in Rheumatoid Arthritis

open access: yesAdvanced Science, EarlyView.
Rheumatoid arthritis is a disease characterized by joint inflammation. Approximately 50% of patients show insufficient response to traditional synthetic disease‐modifying antirheumatic drugs. This study aims to elucidate differential molecular profiles of the mechanisms underlying drug responses through multi‐omics strategy.
