A population-based study of the biology of the thin-level melanoma according to site, Breslow's thickness, and Clark's level was undertaken. Two hundred fifteen patients were studied with a mean follow-up of 41 months. Overall, 23 patients (10.7%) had recurrences, 8 locally, 9 regionally, and 6 systemically, despite an adequate local excision. A multivariate analysis was done. In the patients with thin lesions (less than 1 mm), increasing level (p < 0.002) and head and neck site (p < 0.04) increased the risk of recurrence. Increasing thickness of melanoma up to 1 mm did not influence the risk. This study identifies a group of high-risk melanoma patients for whom adjuvant therapy to decrease recurrences should be studied.

The endometrial and vaginal microbiota have co-evolved with the reproductive tract and play a key role in both health and disease. However, the difference between endometrial and vaginal microbiota, as well as their association with reproductive outcomes in women undergoing frozen embryo transfer, remains unclear. 120 women who underwent in vitro fertilization (IVF)/intracytoplasmic sperm injection (ICSI) and whole embryo freezing were enrolled.

- Brain tumors (BT), both benign and malignant, pose a substantial impact on human health and need precise and early detection for successful treatment. Analysing magnetic resonance imaging (MRI) image is a common method for BT diagnosis and segmentation, yet misdiagnoses yield effective medical responses, impacting patient survival rates. Recent technological advancements have popularized deep learning-based medical image analysis, leveraging transfer learning to reuse pre-trained models for various applications.

Competition is ubiquitous and an important driver of tree mortality. Non-structural carbohydrates (NSCs, including soluble sugars and starch) and C-N-P stoichiometries are affected by the competitive status of trees and, in turn, physiologically determine tree growth and survival in competition. However, the physiological mechanisms behind tree mortality caused by intraspecific competition remain unclear.
