Investigation of trans-to-cis isomerization of cinnamic acid in Arabidopsis using stable-isotope-labeled cinnamic acid.
Biosci Biotechnol Biochem

Cinnamic acid (CA) is a widely distributed metabolite in plant species and is a precursor of many important plant molecules such as lignin and flavonoids. CA exists as both trans and cis isomers; the trans isomer is more common in nature. Previous reports have revealed that the cis isomer of CA (cis-CA) has auxin-like activity when exogenously applied.

Methods: Of the 537 patients with N1a and N1b PTC who underwent surgical treatment at Hyogo Medical University from January 2013 to December 2020 and Shikoku Cancer Center from January 2007 to December 2018, 283 (79 men and 204 women) with lymph node metastasis were analyzed in this study. The median age was 58 (range, 19-93) years, and the median observation period was 73 (range, 1-152) months after surgery.
Article Synopsis
- Cronkhite-Canada syndrome (CCS) is a rare gastrointestinal disorder characterized by taste abnormalities, observed in over 80% of cases, along with various ectodermal issues like nail atrophy and hair loss.
- Ten diagnosed patients underwent assessments for taste function and other symptoms before and after treatment, revealing significant improvements in taste, especially in the anterior tongue.
- The study shows that taste function tests are effective in measuring treatment outcomes, as patients experienced both symptom relief and improved taste function within three months post-treatment.
We present the X-ray crystal structure of a complex between a G-clamp and an internal loop motif of pre-mir-125a, selected from high affinity RNAs identified in a large-scale RNA-binding profile. This X-ray crystal structure reveals that the G-clamp interacts with three distinct guanine bases, forming robust bonds through hydrogen bonding and stacking interactions.

Methods: We measured serum AMH levels in 528 healthy female students at two universities in Japan between 2014 and 2020.
