Molecular Layer Deposition of a Hafnium-Based Hybrid Thin Film as an Electron Beam Resist.

The development of new resist materials is vital to fabrication techniques for next-generation microelectronics. Inorganic resists are promising candidates because they have higher etch resistance, are more impervious to pattern collapse, and are more absorbing of extreme ultraviolet (EUV) radiation than organic resists. However, there is limited understanding about how they behave under irradiation.

Vocal cord biopsy under local anesthesia, with flexible bronchoscope as an outpatient procedure, by "inside-out" technique.

Background: Pulmonologists commonly need to take biopsies of laryngeal lesions, either found incidentally while doing bronchoscopy for other indications or while investigating patients for hoarseness of voice and cough. Biopsy of laryngeal lesions has been conventionally done under general anesthesia to provide adequate samples and minimize risks and patient discomfort. Of late, these biopsies have been done as outpatient procedures, by flexible endoscopes, under local anesthesia.

Skeletal muscle metastases on FDG PET/CT imaging.

Background: Skeletal muscle metastases (SMM) are a rare occurrence despite the fact that skeletal muscle comprises more than 50% of total body mass. When present, most are asymptomatic and are often found incidentally on imaging. Several studies have reported isolated cases of patients with SMM.

Traumatic bilateral carotid artery dissection.

Introduction: Bilateral carotid artery dissection following blunt trauma is a rare but potentially lethal injury if not diagnosed early and treated.

Case Report: We report a collision patient who suffered bilateral asymptomatic carotid artery dissections. He also had multiple fractures of the pelvis and upper and lower extremities.

Comparing the volume of gliomas in the brain in FLAIR and post-contrast T1-weighted MRI sequences.

The imaging modality used to diagnose and monitor brain gliomas is magnetic resonance imaging (MRI), with standard protocols including contrast-enhanced T1-weighted and fluid-attenuated inversion recovery (FLAIR) image sequences. Many clinical trials are currently using contrast-enhanced T1-weighted MR image sequences to evaluate tumor response to treatment, but it is our hypothesis that FLAIR sequences will detect higher tumor volumes and, therefore, should be the preferred image sequence for this purpose. In this retrospective study, a volumetric analysis was conducted on the post-contrast T1-weighted and FLAIR MR image sequences of 38 patients with confirmed brain gliomas.
