Maximum entropy model (Maxent) and geographic information system (GIS) were used to predict the global ecological suitable region of Codonopsis pilosula based on 129 distribution data and 37 ecological factors. The results showed that the total area of ecological suitable region was about 884.79×10 km, mainly in East Asia of the Northern Hemisphere, especially concentrated in China. The ecological suitable region in China with high suitable index was mainly in Shanxi, Shaanxi, Sichuan, southeast of Gansu, east of Tibet, southeast of Yunnan, and the northeast of Shandong. It was indicated that China had the most suitable region for C. pilosula cultivation. The main influence factors for the geographical distribution of C. pilosula were climate factors, and the first factor was temperature, the next one was precipitation, and the topography factors and soil factors followed. Mean annual temperature, precipitation seasonality, mean temperature of coldest quarter and precipitation of driest quarter were the most important factors for the distribution of C. pilosula.

Background And Aims: Even though aging is a known risk factor for prostate cancer incidence and mortality, there has been an increase in incidence among young men since the late 1980s with notably lower survival rates than those among older men. However, there is insufficient knowledge about recent trends in the incidence and survival of this disease.

Methods: We analyzed prostatic cancer incidence trends in men under 50 from 1975 to 2020 using Surveillance, Epidemiology, and End Results (SEER) 8 registries data.

Incorporating ecological connectivity into spatial conservation planning is increasingly recognized as a key strategy to facilitate species movements, especially under changing environmental conditions. However, obtaining connectivity data is challenging, especially in the marine realm. Sea currents are essential for exploring marine structural connectivity, but transforming sea current data into spatial connectivity matrices involves complex and resource-intensive processing steps to ensure accuracy and usability.

Microbiome studies aim to answer the following questions: which organisms are in the sample and what is their impact on the patient or the environment? To answer these questions, investigators have to perform comparative analyses on their classified sequences based on the collected metadata, such as treatment, condition of the patient, or the environment. The integrity of sequences, classifications, and metadata is paramount for the success of such studies. Still, the area of data management for the preliminary study results appears to be neglected.
