The hippocampal formation is a complex brain structure that is important in cognitive processes such as memory, mood, reward processing and other executive functions. Histological and neuroimaging studies have implicated the hippocampal region in neuropsychiatric disorders as well as in neurodegenerative diseases. This highly plastic limbic region is made up of several subregions that are believed to have different functional roles. Therefore, there is a growing interest in imaging the subregions of the hippocampal formation rather than modelling the hippocampus as a homogenous structure, driving the development of new automated analysis tools...

INTRODUCTION: The cerebellopontine angle (CPA) is a subarachnoid space in the lateral aspect of the posterior fossa. In this study, we propose a complementary analysis of the CPA from the cerebellopontine fissure. METHODS: We studied 50 hemi-cerebelli in the laboratory of neuroanatomy and included a description of the CPA anatomy from the cerebellopontine fissure and its relationship with the flocculus and the 5th, 6th, 7th, and 8th cranial nerves (CN) origins. RESULTS: The average distance from the 5th CN to the mid-line (ML) was 19...

Horner syndrome is characterized by the following triad of clinical signs: miosis, ptosis and facial anhidrosis. In addition, iris heterochromia, conjunctival injection, facial erythema, congestive nasal mucosa and apparent enophthalmos secondary to the reduction of the palpebral fissure can appear. It is caused by an interruption of the sympathetic pathway that extends from the hypothalamus to the orbit. Because there is no decussation, the signs are homolateral to the lesion. Traditionally, it is classified as congenital and acquired...

Rachel Wood, Amelia Penny
The ability to encrust in order to secure and maintain growth on a substrate is a key competitive innovation in benthic metazoans. Here we describe the substrate growth dynamics, mode of biomineralization and possible affinity of Namapoikia rietoogensis, a large (up to 1 m), robustly skeletal, and modular Ediacaran metazoan which encrusted the walls of synsedimentary fissures within microbial-metazoan reefs. Namapoikia formed laminar or domal morphologies with an internal structure of open tubules and transverse elements, and had a very plastic, non-deterministic growth form which could encrust both fully lithified surfaces as well as living microbial substrates, the latter via modified skeletal holdfasts...

A 42-year-old man had an unstable Jefferson type IV atlas fracture with unilateral vertebral artery occlusion after a diving accident. We performed C1-ring reconstruction with a crosslink rod and C2 fixation to directly reduce the fracture fissure. Within 6 h, cerebellar hemisphere infarction developed. After decompressive craniectomy, duroplasty, and release of the vertebral artery occlusion caused by the transfixing rod, a postoperative computed tomography angiogram showed that blood flow in the right vertebral artery improved...

OBJECTIVE The objective of this study was to test the hypothesis that midline (interhemispheric or perimesencephalic) traumatic subarachnoid hemorrhage (tSAH) on initial CT may implicate the same shearing mechanism that underlies severe diffuse axonal injury (DAI). METHODS The authors enrolled 270 consecutive patients (mean age [± SD] 43 ± 23.3 years) with a history of head trauma who had undergone initial CT within 24 hours and brain MRI within 30 days. Six initial CT findings, including intraventricular hemorrhage (IVH) and tSAH, were used as candidate predictors of DAI...

It is challenging to redo an anatomical pulmonary resection on the ipsilateral side because of the adhesions or dense fissures caused by the initial anatomic pulmonary resection. Few reports describe surgical techniques for addressing these challenges, especially using a minimally invasive thoracoscopic approach instead of standard thoracotomy. Here, we demonstrate a thoracoscopic right upper lobectomy after an initial anatomic pulmonary resection of the right lower lobe and explain the nuances of performing it...

The functional organization of left and right hemispheres is different, and hemispheric asymmetries are thought to underlie variations in brain function across individuals. In this study, we assess how differences between hemispheres are reflected in Asymmetric Functional Connectivity (AFC), which provides a full description of how the brain's connectivity structure during resting state differs from that of the same brain mirrored over the longitudinal fissure. In addition, we assess how AFC varies across subjects...

Acute myocardial infarction is a clinical cardiac emergency associated with potential and substantial morbidity and mortality. This disorder is triggered by an acute coronary syndrome caused by episodes of plaque ulceration, fissuration, or rupture with subsequent production of thrombogenic material and intravascular thrombus formation. The presence or absence of ST-segment elevation on the ECG defines the two main clinical spectrum of ST-segment elevation or non-ST-segment elevation myocardial infarction. In the last three decades, pharmacological and interventional management as well as in-hospital care have dramatically improved...
