Thermosensitive, injectable, antibacterial glabridin liposome/chitosan dual network hydrogel for diabetic wound healing.

Thermosensitive hydrogels show great potential in healing diabetic wounds, but they are still challenged by the long healing time, risk of infectivity, and accumulation of melanin. Herein, a dual network hydrogel is designed, which consists of chlorogenic acid (CA) modified chitosan (CS) (CA@CS), poly(N-isopropylacrylamide) (PNIPAm), and glabridin liposomes (GL). The gelation transition temperature of the hydrogel is 32-34 °C, which thus endows it with superior injectability at ambient temperature.

Geographical distribution and potential distribution prediction of thirteen species of Citrus L. in China.

Using DIVA-GIS software to study the spatial accumulation of Citrus species, an important economic crop in China. Draw the distribution maps of Citrus to concerning altitude and vegetation, and use DIVA-GIS' Bioclim ecological model and maximum information entropy model Maxent software to estimate the potential distribution areas of various Citrus species. The results show that the Citrus genus is located in the south of Qinling Mountains, mainly in the southwest of China and the coast of southeastern China.

An Autonomous Fruit and Vegetable Harvester with a Low-Cost Gripper Using a 3D Sensor.

Reliable and robust systems to detect and harvest fruits and vegetables in unstructured environments are crucial for harvesting robots. In this paper, we propose an autonomous system that harvests most types of crops with peduncles. A geometric approach is first applied to obtain the cutting points of the peduncle based on the fruit bounding box, for which we have adapted the model of the state-of-the-art object detector named Mask Region-based Convolutional Neural Network (Mask R-CNN).

Using UHPLC Q-Trap/MS as a complementary technique to in-depth mine UPLC Q-TOF/MS data for identifying modified nucleosides in urine.

Modified nucleosides, metabolites of RNA, are potential biomarkers of cancer before the appearance of morphological abnormalities. It is of great significance to comprehensively detect and identify nucleosides in human urine for discovery of cancer biomarkers. However, the lower abundance, the greater polarity and the matrix effects make it difficult to detect urinary nucleosides.
