Quantitative Estimation of Effective Brønsted Acid Sites of Silica-Supported HSiWO Heteropoly Acid for Adsorption of Various Molecules.

The amount of incorporation of linear alcohols and ethers in HSiWO·6HO (HSiW·6HO, 50 wt %) supported on silica (SiO) was estimated by a conventional volumetric method and infrared (IR) spectroscopy, and the state of involved molecules was elucidated. First, the attribution of the key IR band at 2200 cm, which was observed for the water of crystallization of HSiW·6HO, to HO species (protons) was verified by coincident observation of thermogravimetric-differential thermal analysis, X-ray diffraction (XRD), and IR spectroscopy during thermal treatment in addition to the isotope exchange with DO. The 2200 cm band was gradually decreased in intensity by increasing the amount of adsorption of pyridine and was totally consumed at saturation, while the volumetric method provided the accurate number of included pyridine molecules.

Fungal Leadless Pacemaker Endocarditis Managed by Percutaneous Vacuum-Assisted Evacuation of Vegetation, Pacemaker Extraction, and Replacement.

Leadless cardiac pacemakers (LCPs) mitigate the risks of traditional transvenous devices such as lead fracture and infection. Two LCPs are clinically available, using either a helix or tined active fixation approach. There are rare reports of LCP infection-all involving the tined device.

Robotic-assisted laparoscopic radical prostatectomy for treatment of a newly identified lesion revealed no viable cells in the previously treated area with microwave focal therapy.

Introduction: Histological outcome of the targeted focal therapy is in principle confirmed by targeted needle biopsy from the treated area in clinical trial. Herein, we report a rare case in which the MFT was followed by RARP.

Case Presentation: A 68-year-old man with PSA 9.

Reduced dopamine transporter availability in drug-naive adult attention-deficit/hyperactivity disorder.

Aim: This study aimed to clarify the abnormalities in dopamine transporter (DAT) availability in drug-naive adult patients with attention-deficit/hyperactivity disorder (ADHD) and the relationship between ADHD symptoms and abnormalities in DAT availability.

Methods: Single-photon emission tomography (SPECT) was performed using iodine-123-β-carbomethoxy-3β-(4-iodophenyltropane) (I-123 β CIT) as a tracer to measure in vivo DAT availability in 20 drug-naive patients with ADHD [mean age ± standard deviation (SD)]: 25 ± 3.44 years; male:female = 11:9] and 20 age- and sex-matched healthy controls (HCs) (mean age ± SD: 23.
