The impact of sphygmomanometer placement and cuff placement on blood pressure measurements.

Background: Hypertension is the most significant global risk factor for mortality and morbidity, making standardized blood pressure measurement crucial.

Objectives: To investigate whether the location of blood pressure monitors and the positioning of cuffs yield differing results in blood pressure measurements.

Methods: Patients admitted to the Affiliated Hospital of Jiujiang College between 1 January 2022 and 30 June 2023 were enrolled in this study and randomly allocated into four groups.

Congenital absence of the right coronary artery: A case report.

Background: As a rare anomaly, congenital absence of the right coronary artery (RCA) occurs during the development of coronary artery. Patients with congenital absence of the RCA often show no clinical symptoms, and this disease is considered benign. The left coronary artery gives blood supply to the whole myocardium.

Amiodarone-induced muscle tremor in an elderly patient: A case report.

Background: Amiodarone is a Class III antiarrhythmic drug, which has been adopted for the treatment of atrial fibrillation and ventricular arrhythmia. However, the use of amiodarone can cause lower limb muscle tremors, which is recognized as a rare side effect of this medication.

Case Summary: An 84-year-old female was administrated with amiodarone for paroxysmal supraventricular tachycardia and frequent ventricular tachycardia.

Pacemaker electrode rupture causes recurrent syncope: A case report.

Background: Currently, the implantation of permanent cardiac pacemakers entails mostly subclavian vein puncture, which is relatively simpler and easier to master. However, due to individual differences, some patients carry a narrow space between the clavicle and the first rib. If the range of activity of the upper limb is increased, the friction between the electrode wire and the bone gap leads to the breakage of the electrode wire, which is manifested by poor pacemaker perception and pacing.

Preparation, characterization and photocatalytic activities of boron- and cerium-codoped TiO2.

Boron- and cerium-codoped TiO2 photocatalysts were synthesized using modified sol-gel reaction process and characterized by X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), particle size distribution (PSD), diffuse reflectance spectra (DRS), and Brunauer-Emmett-Teller (BET). The photocatalytic activities were evaluated by monitoring the degradation of dye Acid Red B (ARB). The results showed that the prepared photocatalysts were mixed oxides mainly consisting of titania, ceria, and boron oxide.

[Characterization and photocatalytic activity of Ni-doped tiO2 nano photocatalysts prepared by low temperature combustion synthesis].

Ni-doped TiO2 photocatalysts were prepared by low temperature combustion synthesis and some properties, such as optical absorption, crystal type, grain size distribution and chemistry transformation during temperature rising were characterized by UV-Vis DRS, X-ray diffraction (XRD), laser light dispersion grain size measurement machine and TG-DSC respectively. The photocatalytic activities of the prepared photocatalysts under visible light irradiation were evaluated by monitoring the degradation of methylene blue dye, a probe pollutant. The results indicate that the Ni-doped TiO2 photocatalysts prepared by low temperature combustion synthesis shift the optical absorption threshold to visible light, the band gap of 0.

[Degradation of reactive red X-3B by ultra sound synergized with zero-valent iron].

The synergistic effects of ultra sound and zero-valent iron were studied by measuring the degradation of X-3B in zero-valent reduction, ultra sound degradation and synergistic systems. The effects of pH, ultra sound power and irradiation time on the synergistic system were explored. The results show that the X-3B is degraded difficultly by ultra sound and the total removal rate is less than 7.

[Preparation and photocatalytic activity of boron doped CeO2/TiO2 mixed oxides].

Boron doped CeO2/TiO2 mixed oxides photocatalysts were prepared by adding boric acid and cerous nitrate during the hydrolyzation of titanium trichloride and tetrabutyl titanate. XRD, UV-Vis DRS and XPS techniques were used to characterize the crystalline structure, light absorbing ability and the chemical state of Boron element in the photocatalyst sample. The photocatalytic activities were evaluated by monitoring the degradation of acid red B under UV irradiation.

[Photocatalytic degradation of reactive red X-3B by immobilized P25 in a contact oxidation reactor].

The immobilized photocatalyst, P25 supported by glass fiber, was prepared by calcining method. The effect of calcining temperature on the photocatalytic activity and the effect of initial pH and inorganic anions on the photocatalytic degradation of Reactive Red X-3B were explored in a new photocatalytic contact oxidation reactor. The results show that catalyst activity is affected drastically by calcining temperature, the optimal temperature is 300 degrees C; the SEM photos of immobilized catalyst indicated that P25 adhered to glass fiber firmly; The Reactive Red X-3B was more easily degraded in acid solution, when initial pH increasing from 2.
