Anaplastic (Malignant) Meningioma
Meningiomas are the most common primary central nervous system malignancies accounting for 36% of all intracranial tumors. However, only 1% of meningioma is classified as malignant (anaplastic) meningioma. Due to their rarity, clinical management of these tumors presents several gaps.

Anastasios Lymperopoulos
My laboratory for the Study of Neurohormonal Control of the Circulation studies the molecular pharmacology, physiology, and biology of the G protein-coupled receptors (GPCRs) that regulate cardiac function and systemic circulation in general. Particular emphasis is given to autonomic nervous system`s (specifically adrenergic) receptors and to angiotensin II receptors. The general focus is on studying mechanisms underlying abnormal signaling/function of these GPCRs that contribute to heart failure pathophysiology, aiming at discovering and validating novel molecular targets for cardiovascular disease therapy. Our lab`s studies also include novel molecular effects of beta-blockers and angiotensin receptor blockers, two very important drug classes acting through cardiovascular adrenergic and angiotensin receptors, respectively.

Anatomical Resection
Anatomical resection (AR), described as systematic removal of a liver segment confined by tumor-bearing portal tributaries, may improve survival by reducing the risk of tumor recurrence compared with non-AR.

Anatomical-MRI Correlations in Hypertrophic Cardiomyopathy Adults and Children
Hypertrophic Cardiomyopathy (HCM) is the most frequent hereditary cardiovascular disease and the leading cause of sudden cardiac death in young individuals. Advancements in CMR imaging have allowed for earlier identification and more accurate prognosis of HCM. CMR has been validated as a technique with high sensitivity and specificity, very few contraindications, a low risk of side effects, and is overall a good tool to be employed in the management of HCM patients.

Anatomy and Barriers of Ocular Drug Delivery
Ocular diseases profoundly impact patients’ vision and overall quality of life globally. However, effective ocular drug delivery presents formidable challenges within clinical pharmacology and biomaterial science, primarily due to the intricate anatomical and physiological barriers unique to the eye.

Anatomy and General Technique of Hemorrhoidal Embolization
Hemorrhoids are blood cushions located into the anus and lower rectum, acknowledged as a common cause of bleeding, which can reduce the quality of life. The development of minimally invasive techniques such as endovascular embolization of superior rectal artery, "Emborrhoid technique", is an effective treatment, with no pain or ischemic complications, and allows quick patient recovery.

Anatomy of Pelvic Autonomic Nerve System
The pelvic autonomic nerve system is a complex network divided into three parts—the sympathetic, parasympathetic, and enteric nervous systems. The enteric nervous system controls the functions of the gastrointestinal tract and is not associated with the autonomic innervation of the pelvis. Therefore, the sympathetic and parasympathetic nerve plexuses innervate the pelvic viscera. The superior hypogastric plexus (SHP), sympathetic trunk, hypogastric nerves (HNs), and most parts of the inferior hypogastric plexus (IHP) contribute to the sympathetic system of the pelvis.

Anatomy of the Human Nose
The visible part of the human nose is the protruding part of the face that bears the nostrils. The shape of the nose is determined by the ethmoid bone and the nasal septum, which consists mostly of cartilage and which separates the nostrils. On average the nose of a male is larger than that of a female. The nasal root is the top of the nose, forming an indentation at the suture where the nasal bones meet the nasal part of the frontal bone. The anterior nasal spine is the thin projection of bone at the midline on the lower nasal margin, holding the cartilaginous center of the nose. Adult humans have nasal hair in the nostrils.

Anderson–Fabry Disease
Anderson–Fabry disease (AFD) is a lysosome storage disorder resulting from an X-linked inheritance of a mutation in the galactosidase A (GLA) gene encoding for the enzyme alpha-galactosidase A (α-GAL A). This mutation results in a deficiency or absence of α-GAL A activity, with a progressive intracellular deposition of glycosphingolipids leading to organ dysfunction and failure. Cardiac damage starts early in life, often occurring sub-clinically before overt cardiac symptoms. Left ventricular hypertrophy represents a common cardiac manifestation, albeit conduction system impairment, arrhythmias, and valvular abnormalities may also characterize AFD. Even in consideration of pleiotropic manifestation, diagnosis is often challenging. Thus, knowledge of cardiac and extracardiac diagnostic “red flags” is needed to guide a timely diagnosis.

Anderson–Fabry Disease and Neurodegeneration
Anderson–Fabry disease (AFD) is an inherited lysosomal storage disorder characterized by a composite and multisystemic clinical phenotype and frequent involvement of the central nervous system (CNS). Research in this area has largely focused on the cerebrovascular manifestations of the disease, and very little has been described about further neurological manifestations, which are known in other lysosomal diseases, such as Gaucher disease. In particular, a clinical and neuroimaging phenotype suggesting neurodegeneration as a putative mechanism has never been fully described for AFD.
