The curious skink, Carlia ailanpalai Zug, occurs in the main group of the Admiralty Islands of Papua New Guinea but has also successfully invaded Guam, the Marianas, Yap, and Kosrae. A single coccidian, Eimeria zugi McAllister, Duszynski, Fisher, & Austin, 2013 was described from C. ailanpalai from Papua New Guinea.

Taxonomic profiling of microbial communities is essential to model microbial interactions and inform habitat conservation. This work develops approaches in constructing training/testing data sets from publicly available marine metagenomes and evaluates the performance of machine learning (ML) approaches in read-based taxonomic classification of marine metagenomes. Predictions from two models are used to test accuracy in metagenomic classification and to guide improvements in ML approaches.

Objective: To assess the value of preliminary testicular core extraction (TCE) as a tool for determining whether to pursue clinic testicular extraction (cTESE) versus microscopic testicular sperm extraction (mTESE) to minimize both financial burden and procedural complexity.

Methods: All men with non-obstructive azoospermia (NOA) from 2018 to 2022 who underwent clinic TCE were analyzed. Patients who were found to have sperm on initial TCE were recommended cTESE.

Article Synopsis
  • Climate change significantly interacts with biological invasions, complicating the management of invasive species, especially snakes on islands, which threaten local ecosystems.
  • The study examines the California kingsnake's (Lampropeltis californiae) potential distribution in Gran Canaria under current and future climate conditions, indicating the islands are currently suitable for this invasive species and may become even more suitable due to climate change.
  • The findings highlight the increasing threat invasive reptiles pose to near-tropical regions and emphasize the need for further research to understand their impacts on global biodiversity.

Lynch Syndrome/HNPCC is a syndrome of cancer predisposition linked to inherited mutations of genes participating in post-replicative DNA mismatch repair (MMR). The spectrum of cancer associated with Lynch Syndrome includes tumours of the colorectum, endometrium, ovary, upper gastrointestinal tract and the urothelium although other cancers are rarely described. We describe a family of Lynch Syndrome with an hMLH1 mutation, that harbours an unusual tumour spectrum and its diagnostic and management challenges.
