The Amazon rainforest has approximately 23% of its sampled area dedicated to bats, making it one of the least sampled and most diverse regions for bats in Brazil. The lack of sampling results in a lack of knowledge regarding the accurate geographical distribution of bat species. This lack is referred to as the Wallacean shortfall, which should be addressed with primary data obtained from in situ collections.

- - The study investigates basilar artery perforator aneurysms (BAPAs), which are rare compared to regular aneurysms, focusing on their presentation, imaging features, and outcomes.
- - Researchers analyzed cases of BAPAs from a neurovascular database and found that out of 739 patients with subarachnoid hemorrhage, 9 had BAPAs, which were more common in males but showed similar severity to non-perforator aneurysms.
- - Most BAPAs were initially missed on CT angiography, but showed significant enhancement on vessel wall imaging; the majority spontaneously thrombosed with conservative management, leading to no complications or rebleeds.
Objectives: To determine the compliance of online vendors to the UK Opticians Act 1989 Section 27 requirements and safety regulations for cosmetic contact lens (CCL) sales and the quality of online CCL health information.
Methods: The top 50 websites selling CCLs on each three search engines, namely Google, Yahoo, and Bing, were selected. Duplicates were removed, and the remaining websites were systematically analyzed in February 2023.
Intracranial aneurysms are common, but only a minority rupture and cause subarachnoid haemorrhage, presenting a dilemma regarding which to treat. Vessel wall imaging (VWI) is a contrast-enhanced magnetic resonance imaging (MRI) technique used to identify unstable aneurysms. The pathological basis of MR enhancement of aneurysms is the subject of debate.

Therapeutic options are very limited, and patients often show little functional improvement over time. Neuroimaging studies have demonstrated that a significant number of PDOC patients retain a high level of cognitive functioning, and in some cases even awareness, and are simply unable to show this with their external behavior - a condition known as cognitive-motor dissociation (CMD).
