 (Primulaceae), a new species from Guangxi, China.

(Subgen. Idiophyton, Primulaceae), a new species from Guangxi, China, is here described and illustrated based on morphological data. Although it shares similarities with , , and , there are distinguishing characteristics that set it apart.

 (Meliaceae), a new species from Guangxi, China.

(Meliaceae), a new species from Guangxi, China, is here described and illustrated. The new species is easily distinguishable from the other two Chinese members of the genus by its petals being pale yellow, filaments being connate into tubes above the middle, the berry being oval and glabrous. An identification key of for 17 species is also provided.

The Prevalence of Smartphones and WeChat Use Among Older Adults With Chronic Disease in a Western China.

Telemedicine is a promising way to deliver patient education and health services, but access to information technology among potential patients is a prerequisite. This study surveyed the prevalence of smartphone use and the use of the Chinese social networking platform WeChat and Wi-Fi access in the homes of older adults in a western area of China. A convenience sample of 225 older adults with chronic diseases in two tertiary hospitals was interviewed regarding smartphone ownership, WeChat use, and access to Wi-Fi at home.

20S proteasome and glyoxalase 1 activities decrease in erythrocytes derived from Alzheimer's disease patients.

As a result of accumulating methylglyoxal and advanced glycation end products in the brains of patients with Alzheimer's disease, it is considered a protein precipitation disease. The ubiquitin proteasome system is one of the most important mechanisms for cells to degrade proteins, and thus is very important for maintaining normal physiological function of the nervous system. This study recruited 48 individuals with Alzheimer's disease (20 males and 28 females aged 75 ± 6 years) and 50 healthy volunteers (21 males and 29 females aged 72 ± 7 years) from the Affiliated Hospital of Youjiang Medical University for Nationalities (Baise, China) between 2014 and 2017.

Two novel MOF-74 analogs exhibiting unique luminescent selectivity.

Two MOF-74 analogs with OH groups on 1D channel surfaces have been synthesized through multi-component self-assembly at room temperature. Their guest-free forms demonstrate a potential luminescent probe or sensor for small molecules, and OH-MOF-74 (2a) also showed exceptional fluorescence quenching and enhancement behavior for different types of aromatic molecules.
