Comparison of transabdominal wall specimen retrieval and natural orifice specimen extraction robotic surgery in the outcome of colorectal cancer treatment.

Background: Natural orifice specimen extraction surgery (NOSES), as a new star of minimally invasive techniques, has been increasingly favored and promoted in the field of surgery around the world. Most previous studies were comparative studies of laparoscopic NOSES and conventional laparoscopic surgery. However, there is little research on comparing robotic colorectal cancer NOSES with conventional robotic-assisted colorectal cancer resection surgery.

[Temporal and Spatial Variation Characteristics of Methane, Carbon Dioxide, and Nitrous Oxide Concentrations and the Influencing Factors in Small Aquaculture Pond].

As an important source of greenhouse gases, the changes in greenhouse gas concentrations of aquaculture ponds are not only the basis for accurate quantification of greenhouse gases emissions but are also important for identifying their influencing factors. The spatial and temporal variation characteristics of CH, CO, and NO concentrations and the influencing factors in a typical small aquaculture pond in the Yangtze River Delta were analyzed based on the headspace equilibrium-gas chromatograph method. Except in spring, the concentrations of CH, and NO appeared high at noon or afternoon and were influenced by water temperature.

[Spatiotemporal variations of wet-bulb temperature and its impact factors of Nanjing urban neighborhood].

Global climate change and local urban heat islands enhance urban heat stress. Studies focused at the urban neighborhood scale are limited. Wet-bulb temperature represents the combined effects of both temperature and humidity, and therefore can more accurately reflect human thermal comfort.
