Oxygen Vacancy Enabled Electronic Structure Engineering of Pt-WO Nanosheets toward Highly Efficient BTEX Sensing.

A Pt nanoparticle-immobilized WO material is a promising candidate for catalytic reactions, and the surface and electronic structure can strongly affect the performance. However, the effect of the intrinsic oxygen vacancy of WO on the d-band structure of Pt and the synergistic effect of Pt and the WO matrix on reaction performance are still ambiguous, which greatly hinders the design of advanced materials. Herein, Pt-decorated WO nanosheets with different electronic metal-support interactions are successfully prepared by finely tuning the oxygen vacancy structure of WO nanosheets.

Aortic Artery and Cardiac Valve Calcification are Associated with Mortality in Chinese Hemodialysis Patients: A 3.5 Years Follow-up.

Background: This study was to investigate the relationship among aortic artery calcification (AAC), cardiac valve calcification (CVC), and mortality in maintenance hemodialysis (MHD) patients.

Methods: All MHD patients in Shanghai Ruijin Hospital in July 2011 were included. To follow up for 42 months, clinical data, predialysis blood tests, echocardiography, and lateral lumbar X-ray plain radiography results were collected.

Association of E/E' and NT-proBNP with renal function in patients with essential hypertension.

Objectives: To evaluate the association of left ventricular (LV) diastolic function and N-terminal pro-brain natriuretic peptide (NT-proBNP) with renal function in essential hypertension.

Methods: LV diastolic function was estimated by the ratio of early diastolic velocities (E) from transmitral inflow to early diastolic velocities (E') of tissue Doppler at mitral annulus (septal corner); NT-proBNP was measured in 207 hypertensive patients (mean age 56±14 years). The subjects were classified into 3 groups: E/E'≤10 group (n = 48), 1015 group (n = 50).

[Accessory mitral valve: report of four cases and literature review].

Objective: To describe the echocardiographic and clinical findings of patients with accessory mitral valve (AMV).

Methods: Four adult patients were diagnosed to have AMV by Doppler echocardiography.

Results: All the four patients had cardiac murmur but 2 were asymptomatic.

A primary right atrium paraganglioma in a 15-year-old patient.

Thoracic pheochromocytomas account for less than 2% of reported cases, while primary cardiac paragangliomas are even rare. The following case illustrates a 15-year-old patient with primary right atrium paraganglioma. This patient was referred for paroxysmal hypertension and excessive perspiration.
