Purpose: The incidence of gastroparesis is higher in individuals diagnosed with type 2 diabetes mellitus (T2DM) compared to the healthy individuals. Our study aimed to explore the risk factors for gastroparesis in T2DM and to establish a clinical prediction model (nomogram).
Methods: Our study enlisted 694 patients with T2DM from two medical centers over a period of time.
Double fertilization is a unique and particularly complicated process for the generation alternation of angiosperms. Sperm cells of angiosperms lose the motility compared with that of gymnosperms. The sperm cells are passively carried and transported by the pollen tube for a long journey before targeting the ovule.

Objective: To determine the effectiveness of a novel multifaceted intervention for obesity prevention in primary school children.
Design, Setting, And Participants: A cluster randomized clinical trial was conducted during a single school year (from September 11, 2018, to June 30, 2019) across 3 socioeconomically distinct regions in China according to a prespecified trial protocol.
Membrane fouling can be effectively addressed by modifying the membrane to realize anti-fouling capability together with real-time fouling detection. Here, we present the synthesis and water treatment testing of a promising candidate for this application, a composite membrane of polyvinylidene fluoride (PVDF) and functionalized carbon nano-materials prepared by a facile phase inversion method. The synergistic effect of oxidized multi-walled carbon nanotubes (OMWCNTs) and graphene oxide (GO) enabled better surface pore structures, higher surface roughness, hydrophilicity, and better antifouling property as compared with that of pristine PVDF membranes.

- Ectothermic animals in cold regions usually grow slower due to limited activity and food, but Qinghai toad-headed lizards grow faster at high elevation compared to low elevation.
- High-elevation juvenile lizards had greater growth rates in the wild, though laboratory growth rates were similar across elevations, and they maintained higher body temperatures despite similar air temperatures.
- The growth difference is likely due to environmental factors like better food availability and higher body temperatures, rather than genetic differences.
High-performance, flexible film heaters with carbon nanotube transparent conducting films are easily fabricated by both a rod-coating method and a spraying method. The main conclusion we have reached is that the film demonstrates a heating rate of 6.1°C s at 35 V and sheet resistance as low as 94.

- Body size is important for life traits like growth and reproduction, but understanding its variation, especially with altitude, is still a challenge in research.
- A study on toad-headed lizards at different elevations in the Qinghai-Tibetan Plateau revealed that high-elevation lizards grew faster and reached larger sizes compared to their low-elevation counterparts.
- However, the newborns from high-elevation females were smaller, suggesting that environmental factors and resource availability might influence growth rates and ultimately body size differently at varying altitudes.
Objective: To determine the suitable extraction technology of diester-type alkaloids, such as mesaconitine, aconitine and hypaconitine from the roots of Aconitum carmichaeli (Radix Aconiti lateralis).
Methods: The contents of mesaconitine, aconitine and hypaconitine were determined by HPLC. Single-factor experiment was used to study the extraction factors.
Objective: To compare the diagnostic efficacy of whole-body diffusion-weighted imaging (WB-DWI) and [18F] fluoro-2-D-glucose PET/CT(FDG-PET/CT)for assessment of non-small cell lung cancer (NSCLC) patients.
Materials And Methods: A group of 56 patients (21 female, 35 male; 35-76 years) with NSCLC proved by pathologic examination or follow-up imaging findings was set as reference standards, and all patients underwent both WB-DWI at 1.5T (MAGNETOM Avanto) and PET/CT (Biograph 16).
Three new limonoids, cipadesins D--F (1--3), together with 8,15-dihydroxy-13E-labdane, beta-sitosterol and beta-daucosterol, were isolated from the leaves and bark of Cipadessa cinerascens. Their structures were elucidated by spectral evidence. X-Ray crystallographic analysis confirmed the structure of 1.
