Serendipitous XMM-Newton discovery of a cluster of galaxies at z=0.28 [PDF]

, 2007
We report the discovery of a galaxy cluster serendipitously detected as an extended X-ray source in an offset observation of the group NGC 5044. The cluster redshift, z=0.281, determined from the optical spectrum of the brightest cluster galaxy, agrees ...

Evolutionary radiation of large‐bodied gorgonopsians from the lower Abrahamskraal formation of South Africa

The Anatomical Record, EarlyView.
Abstract The middle Permian represents a critical interval in therapsid evolution, when gorgonopsians emerged as some of the first specialized apex predators within terrestrial ecosystems. Despite their significance, the early diversification of Gorgonopsia in Gondwana remains poorly understood due to scarcity and fragmentary material.

Posterior arterial circle of Willis anatomic variations and coronary artery dominance: is there a correlation?

Autopsy and Case Reports, 2011
Anatomic variations and anomalies in the arteries from the circle of Willis or the heart are common, sometimes even more common than the classic morphology.

Determination of the Unilaterally Damaged Region May Depend on the Asymmetry of Carotid Blood Flow Velocity in Hemiparkinsonian Monkey: A Pilot Study

Parkinson's Disease, 2022
The hemiparkinsonian nonhuman primate model induced by unilateral injection of 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) into the carotid artery is used to study Parkinson’s disease.

‘SOMS BrainSpace’: A digital serious game for undergraduate neuroscience

Anatomical Sciences Education, EarlyView.
Abstract Neuroanatomy is challenging for many undergraduates, requiring strong visuospatial skills and a deep understanding of complex concepts. This study developed and evaluated SOMS BrainSpace, a digital serious game for neuroanatomy education, using a mixed methods approach.

Average dimensions of the vessels at the base of the brain and the embryological basis of its variations

National Journal of Clinical Anatomy, 2013
Background and aims: The cerebral circulation is constantly maintained by the anastomotic circle of Willis which is often anomalous in more than 50% of the normal adult brains. These anomalies increase the risk of the stroke and transient ischemic attack

Baseline coral disease surveys within three marine parks in Sabah, Borneo [PDF]

, 2015
Two of the most significant threats to coral reefs worldwide are bleaching and disease. However, there has been a scarcity of research on coral disease in South-East Asia, despite the high biodiversity and the strong dependence of local communities on ...

Integrating yoga into anatomy and clinical medicine education: A holistic approach to learning

Anatomical Sciences Education, EarlyView.
Abstract Anatomical knowledge is fundamental for success in clinical settings. Unfortunately, anatomy education within professional health programs has experienced a continual decrease in contact hours and curricular content over the previous two decades, leading to deficits and potential gaps in anatomical science knowledge.

Data on vessel wall thickness measurements of intracranial arteries derived from human circle of Willis specimens

Data in Brief, 2018
In this article, we report data on vessel wall thickness parameters derived from different arterial segments of the circle of Willis and its primary branches in patients with and without cerebrovascular disease.
