The influence of a soil amendment on the abundance and interaction of arbuscular mycorrhizal fungi with arable soils and host winter wheat.

Access Microbiol

January 2024

Department of Clinical, Pharmaceutical and Biological Science, School of Life and Medical Sciences, College Lane Campus, University of Hertfordshire, Hatfield, Hertfordshire AL10 9AB, UK.

Arbuscular mycorrhizal (AM) fungi have been shown to be associated with an estimated 70 % of vascular terrestrial plants. Such relationships have been shown to be sensitive to soil disturbance, for example, tillage in the preparation of a seed bed. From the application of arable soil management, AM fungal populations have been shown to be negatively impacted in abundance and diversity, reducing plant growth and development.

Background: Protein Tyrosine Phosphatase Receptor Type D (PTPRD) is involved in the regulation of cell growth, differentiation, and oncogenic transformation, as well as in brain development. PTPRD also mediates the effects of asprosin, which is a glucogenic hormone/adipokine derived following the cleavage of the C-terminal of fibrillin 1. Since the asprosin circulating levels are elevated in certain cancers, research is now focused on the potential role of this adipokine and its receptors in cancer.

Development and evaluation of 2,4-disubstituted-5-aryl pyrimidine derivatives as antibacterial agents.

Arch Pharm (Weinheim)

April 2024

Helmholtz Institute for Pharmaceutical Research Saarland (HIPS), Helmholtz Centre for Infection Research, Saarland University Campus, Saarbrücken, Germany.

Designing novel candidates as potential antibacterial scaffolds has become crucial due to the lack of new antibiotics entering the market and the persistent rise in multidrug resistance. Here, we describe a new class of potent antibacterial agents based on a 5-aryl-N,N-dibutylpyrimidine-2,4-diamine scaffold. Structural optimization focused on the 5-aryl moiety and the bioisosteric replacement of the side chain linker atom.

Article Synopsis
  • The study developed copper oxide nanoparticles (CuO NPs) using essential oils from oleogum resin, applying microwave energy, and then loaded them with the anticancer drug carboplatin, creating a combination known as Cr@CuO NPs.
  • Characterization techniques like high-resolution electron microscopy and X-ray diffraction were used to analyze the properties of the synthesized nanoparticles, which showed effective release profiles and high entrapment efficiency for carboplatin.
  • Results indicated that Cr@CuO NPs exhibited significantly higher cytotoxicity against human colon cancer cells than either free carboplatin or CuO NPs alone, demonstrating their potential as a more effective cancer treatment through enhanced apoptosis and gene activity modulation.

Article Synopsis
  • This study aimed to evaluate cases of local anaesthetic systemic toxicity (LAST) specifically in adult urological patients by reviewing literature from various medical databases over several decades.
  • Out of 157 publications screened, only six case reports were eligible, documenting instances where patients experienced LAST after procedures like penile dorsal nerve blocks and circumcision, with most patients recovering without long-term issues.
  • The findings suggest that while LAST is rare in adult urology, urologists should recognize its symptoms and manage it effectively while following guidelines on safe dosing of local anaesthetics to minimize the risk.
