Article Synopsis
  • Osteoarthritis is a major cause of joint pain and disability, and intra-articular corticosteroid injections (IACs) are commonly used when other treatments fail, providing short-term symptom relief.
  • A study involving interviews with 38 patients and 19 primary care clinicians revealed differing perspectives on IACs, highlighting themes such as access, trust, effectiveness, and clinicians' caution regarding treatment risks and guidelines.
  • Both patients and clinicians generally recognize the benefits of IACs in improving quality of life, but there is notable variability in treatment access and clinicians' confidence that influences decision-making.

The development of nonopioid analgesics for the treatment of abdominal pain is a pressing clinical problem. To address this, we examined the expression of Gi/o-coupled receptors, which typically inhibit nociceptor activation, in colonic sensory neurons. This led to the identification of the orphan receptor GPR35 as a visceral analgesic drug target because of its marked coexpression with transient receptor potential ankyrin 1 (TRPA1), a mediator of noxious mechanotransduction in the bowel.

Halide solid electrolytes do not currently display ionic conductivities suitable for high-power all-solid-state batteries. We explore the model system AZrCl (A = Li, Na, Cu, Ag) to understand the fundamental role that A-site chemistry plays on fast ion transport. Having synthesised the previously unknown AgZrCl we reveal high room temperature ionic conductivities in CuZrCl and AgZrCl of 1 × 10 and 4 × 10 S cm, respectively.

Article Synopsis
  • - The CRISPR-Cas9 system has improved the ability to genetically manipulate the pathogenic yeast, enabling single-step creation of homozygous mutants for swift gene screening related to specific phenotypes.
  • - However, the use of Cas9 can lead to unintended loss of heterozygosity (LOH), which may produce changes in the yeast that are unrelated to the targeted gene function.
  • - The study aimed to explore genes overexpressed in fluconazole-resistant strains by using dual antibiotic resistance markers for gene deletion, but while it increased homozygous deletion mutants, it didn't prevent unwanted LOH, highlighting a critical issue in the method.
