Chinese yew, Taxuschinensisvar.mairei is an endangered shrub native to south-eastern China and is widely known for its medicinal value. The increased cultivation of Chinese yew has increased the incidence of various fungal diseases. In this study, Pestalotioid fungi associated with needle spot of Chinese yew were isolated from Guangxi Province. Based on morphological examinations and multi-locus (ITS, , ) phylogenies, these isolates were identified to five species, including two new species, and , two potential novel species, sp. 3 and sp. 4, with a known species (), firstly recorded from Chinese yew. These two new species were morphologically and phylogenetically distinct from the extant Pestalotioid species in Chinese yew. Pathogenicity and culture characteristic tests of these five Pestalotioid species were also performed in this study. The pathogenicity test results revealed that sp. 3 can cause diseases in Chinese yew needles. These results have indicated that the diversity of Pestalotioid species associated with Chinese yew was greater than previously determined and provided helpful information for Chinese yew disease diagnosis and management.

Triple-negative breast cancer (TNBC) is the most aggressive subtype of breast cancer, characterized by the loss or low expression of estrogen receptor (ER), human epidermal growth factor receptor 2 (HER2) and progesterone receptor (PR). Due to the lack of clear therapeutic targets, paclitaxel (PTX) is often used as a first-line standard chemotherapy drug for the treatment of high-risk and locally advanced TNBC. PTX is a diterpenoid alkaloid extracted and purified from Taxus plants, functioning as an anticancer agent by inducing and promoting tubulin polymerization, inhibiting spindle formation in cancer cells, and preventing mitosis.

A specimen from the same collection with identical label data but belonging to Coelopacidia Enderlein (Tephritidae) is hereby identified as the correct holotype and the species should therefore be referred to as Coelopacidia cylindrica (Walker, 1853).

The growing burden of CAD in Asia and the emergence of novel CT-based risk markers highlight the need for an automated platform that integrates patient data with CCTA findings to provide tailored, accurate cardiovascular risk assessments. This study aims to develop an artificial intelligence (AI)-driven platform for CAD assessment using CCTA in Singapore's multiethnic population.

Article Synopsis
- * Currently, paclitaxel is produced through a semi-synthesis process, using a compound called baccatin III extracted from Taxus plants, although many biosynthesis intermediates remain unknown.
- * Recent genomic studies have identified key genes for baccatin III and paclitaxel biosynthesis, which could lead to advancements in understanding the full biosynthetic pathway and improving industrial production through synthetic biology, despite ongoing significant challenges.
The relationships between sleep and adiposity amongst multi-ethnic Asian populations: a cross-sectional analysis of the Health for Life in Singapore (HELIOS) study.

Background: Short sleep duration and poor sleep quality have been associated with obesity. Asian populations report shorter sleep duration compared to other groups. We therefore aimed to explore the relationships between sleep duration, sleep quality, dozing, daytime napping, snoring, insomnia and adiposity in a multi-ethnic Asian population, and investigate the potential contribution of disturbed sleep to the risk of obesity amongst Asian populations.
