AI Article Synopsis

  • Natural acidified marine systems (ASs) are naturally occurring environments with low pH levels caused by volcanic activity and biological processes, serving as vital areas to study ocean acidification (OA).
  • Research demonstrates that ASs worldwide exhibit similar ecological declines, such as the loss of calcareous organisms and essential species, underscoring the impact of OA.
  • Future efforts should focus on enhancing collaboration in research, providing public access to data, and protecting these sites as human heritage through non-destructive methods.

Article Abstract

Natural acidified marine systems (ASs) are environments with relatively low pH levels due to natural causes such as volcanic activity, geochemical reactions, and biological processes. These systems act as natural laboratories for the study of the effects of ocean acidification, allowing for the observation of long-term ecological and evolutionary responses. Understanding these systems is crucial for predicting the effects of anthropogenic ocean acidification (OA) on marine ecosystems. There are 23 ASs in which scientific research has shown significant parallelisms in their results worldwide, such as the disappearance of calcareous organisms and the loss of species with key ecological functions under OA conditions. Future research should emphasize continuous collaboration among teams, as well as public access to oceanographic and biological data along with the monitoring of environmental variables at each AS. To preserve these areas, it is imperative to employ non-destructive methods and protect them as human heritage sites.

Electronic address:

This study investigates the effects of combined compound acidifiers and plant essential oils on the production performance, egg quality, and health parameters of Xianjv chickens. A total of 240 healthy 34-week-old Xianjv chickens were randomly divided into 5 groups and given 5 different feed additives: a control group with a basal diet, and four experimental groups with varying doses of compound acidifiers (CA) and essential oils (EO). The results revealed that the addition of compound acidifiers and essential oils did not significantly affect average daily feed intake, egg production rate, or feed-to-egg ratio.

Multi-drug-resistant Mycobacterium tuberculosis is an escalating global health problem, and a strong pipeline of novel compounds is needed to combat rising antimicrobial resistance. Ecumicin is a novel analogue of the natural antimycobacterial cyclic peptide ecumicin, with selective activity against Mycobacterium species. The activity of ecumicin∗ was compared to that of frontline tuberculosis therapies under in vitro conditions representative of niches where M.

Dynamic interplay of autophagy and membrane repair during Mycobacterium tuberculosis Infection.

PLoS Pathog

Autophagy plays a crucial role in the host response to Mycobacterium tuberculosis (Mtb) infection, yet the dynamics and regulation of autophagy induction on Mtb-containing vacuoles (MCVs) remain only partially understood. We employed time-lapse confocal microscopy to investigate the recruitment of LC3B (LC3), a key autophagy marker, to MCVs at the single cell level with our newly developed workflow for single cell and single MCV tracking and fluorescence quantification. We show that approximately 70% of MCVs exhibited LC3 recruitment but that was lost in about 40% of those MCVs.

Anaerobic digestion is a sustainable technology for methane (CH) production from organic waste and wastewater. However, its performance is frequently hindered by excessive acidification in readily acidified substrates, such as starch wastewater. Oyster shell (OS), a natural alkaline material, effectively regulates pH and enhances CH production.
