Article Synopsis
- * Patients ranged from 27 to 70 years old, with common symptoms including abdominal distension and pain; the imaging revealed different characteristics for localized versus diffuse OMM types.
- * Despite all patients undergoing surgery, survival outcomes varied significantly, with all localized OMM patients surviving, while most of those with diffuse OMM had worse prognoses.
Article Synopsis
- COVID-19, specifically the SARS-CoV-2 Omicron subvariant BA.2, is primarily affecting many countries, and understanding its impact on patients is crucial for better clinical management.
- A study analyzed 805 patients with mild or moderate BA.2 infections, revealing that the majority experienced mild symptoms like fever and cough, while 6.6% showed signs of pneumonia on HRCT scans.
- The findings indicated that lung issues were generally mild, predominantly presenting as ground-glass opacity, and most patients eventually recovered after short-term follow-up.
Objective: The objective of this study is to investigate the diagnosis of dynamic volume computed tomography (CT) for pulsatile tinnitus caused by sigmoid sinus diverticulum (SSD) and bone defects.
Methods: Data obtained by dynamic volume CT from 35 patients with SSD were retrospectively collected. Then the ear morphological parameters, including bone defect, transverse sinus stenosis, position of the jugular bulb, jugular bulb diverticulum, defect of the jugular bulb wall, gross venous sinus thrombosis and SSD, and blood perfusion parameters, including cerebral blood flow (CBF), cerebral blood volume (CBV), and mean transit time (MTT), were evaluated and compared between the tinnitus side and the asymptomatic side of the ear.
In this article, the trajectories of -deoxyephedrine (SBD) along molecular channels within the complex protein structure of third dopamine receptor (DR) are analyzed via molecular dynamic techniques, including potential mean force calculations of umbrella samplings from the 4.5 version of the GROMACS program. Changes in free energy due to the movement of SBD within DR are determined, and the molecular dynamic mechanisms of SBD transmitting along molecular channels are probed.

Methods: A total of 55 patients with implanted intracranial clips or coils (24 men and 31 women; mean age 60.15 ± 15.
Rationale And Objectives: Using lower tube voltage can reduce the exposure to radiation and the dose of contrast agent. However, lower tube voltage is often linked to more noise and poor image quality, which create a need for more effective technology to resolve this problem. To explore the feasibility of coronary computed tomographic angiography (CCTA) in patients with obesity at low tube voltage (100 kV) and low contrast agent concentration (270 mg/mL) using iterative reconstruction.

Methods: The CT data of the 120-kV group (n = 30) were reconstructed with filtered back projection (FBP) algorithm. The CT data of the 100-kV group (n = 30) were reconstructed with FBP as well as AIDR-3D algorithms.
