Experimental and Theoretical Force Constants as Meaningful Indicator for Interatomic Bonding Characteristics and the Specific Case of Elemental Antimony.

Stable Sb exhibits a rhombohedral structure, often referred to as distorted primitive cubic, with each Sb atom having three short and three longer first neighbor bonds. However, this crystal structure can also be interpreted as being layered, putting emphasis on only three short first neighbor bonds. Therefore, temperature-dependent extended X-ray absorption fine structure (EXAFS) spectroscopy is carried out at the Sb K-edge in order to obtain more detailed information on local structural and vibrational properties.

Clinical Phenotype of Behavioral-Variant Frontotemporal Dementia Reversed by ECT: A Case Report.

Introduction: Diagnosis of frontotemporal dementia (FTD) remains difficult even in the presence of core clinical and imaging features. Furthermore, disease-modifying treatments are lacking.

Case Presentation: Here, we report a case of a patient with clinical and imaging features of FTD.

Relationship Between Posttraumatic Headache and Depression After Mild Traumatic Brain Injury.

Objective: Mild traumatic brain injury (mTBI) can lead to psychiatric and somatic symptoms for some patients, including posttraumatic headache (PTH) and depression. This study attempted to further establish the relationship between PTH and depression following mTBI and investigate whether the presence of PTH immediately following injury can identify patients at risk for developing depressive symptoms up to 6 months later.

Methods: This study was a secondary analysis of data from Head Injury Serum Markers for Assessing Response to Trauma (HeadSMART), a prospective study of adult patients in the emergency department with head injury.
