Digest: Species collapse from disturbance occurs quickly, and recovery is slow.

Published: August 2019

In certain conditions, newly-formed species pairs may revert to one species. Zhang et al. modeled the impact of disturbance on incipient species in a predator-prey model and found that species collapse may occur rapidly following disturbance. A distinct species pair can sometimes be re-established if previous conditions are restored, but this depends on the type of disturbance as well as the amount of time that passes after a collapse.

Point-of-care ultrasound in the diagnosis of hepatic gas gangrene.

J Ultrasound

January 2025

Argentinian Critical Care Ultrasonography Association (ASARUC), Buenos Aires, Argentina.

Hepatic gas gangrene (HGG) is a rare but life-threatening condition typically caused by anaerobic bacteria such as Clostridium perfringens, though Gram-negative bacteria like Escherichia coli and Klebsiella species have also been implicated. Traditionally diagnosed via computed tomography (CT), point-of-care ultrasound (POCUS) has emerged as a valuable tool in critical care settings for its non-invasive, bedside utility. We report the case of a 51-year-old female with choledochal syndrome secondary to cholangiocarcinoma who developed HGG following left extended hepatectomy and biliary reconstruction.

Natural variation of CTB5 confers cold adaptation in plateau japonica rice.

Nat Commun

January 2025

Frontiers Science Center for Molecular Design Breeding, Beijing Key Laboratory of Crop Genetic Improvement, College of Agronomy and Biotechnology, China Agricultural University, Beijing, China.

During cold acclimation in high-latitude and high-altitude regions, japonica rice develops enhanced cold tolerance, but the underlying genetic basis remains unclear. Here, we identify CTB5, a homeodomain-leucine zipper (HD-Zip) transcription factor that confers cold tolerance at the booting stage in japonica rice. Four natural variations in the promoter and coding regions enhance cold response and transcriptional regulatory activity, enabling the favorable CTB5 allele to improve cold tolerance.

Fish are ectothermic animals with temperature playing a key role in their health, growth and survival. Greater occurrence of heat waves and temperature extremes, as a result of global climate change, has the potential to impact both wild and farmed populations. Within aquaculture, production is threatened by a multitude of stressors, including adverse temperatures.

A promising future for breast cancer therapy with hydroxamic acid-based histone deacetylase inhibitors.

Bioorg Chem

January 2025

Department of In Vitro Carcinogenesis and Cellular Chemotherapy, Chittaranjan National Cancer Institute, 37, S. P. Mukherjee Road, Kolkata 700026, India. Electronic address:

Histone deacetylases (HDACs) play a critical role in chromatin remodelling and modulating the activity of various histone proteins. Aberrant HDAC functions has been related to the progression of breast cancer (BC), making HDAC inhibitors (HDACi) promising small-molecule therapeutics for its treatment. Hydroxamic acid (HA) is a significant pharmacophore due to its strong metal-chelating ability, HDAC inhibition properties, MMP inhibition abilities, and more.

Seasonal Pattern of Endo-β-Mannanase Activity During Germination of , Exhibiting Morphophysiological Dormancy.

Plants (Basel)

January 2025

Department of Interdisciplinary Program in Smart Agriculture, Kangwon National University, Chuncheon 24341, Republic of Korea.

Morphophysiological dormancy (MPD) is considered one of the most primitive dormancy classes among seed plants. While extensive studies have examined the occurrence of endo-β-mannanase in seeds with physiological dormancy (PD) or non-dormancy, little is known about the activity of this enzyme in seeds with MPD. This study aimed to investigate the temporal and spatial patterns of endo-β-mannanase activity during dormancy break and germination.
