Accuracy assessment of the Tensoval duo control according to the British and European Hypertension Societies' standards

OBJECTIVE: Noninvasive blood pressure (BP) measurement is dependent on either auscultation or oscillometry. The Tensoval duo control device uses auscultatory and/or oscillometric technology to determine BP. We evaluated the accuracy of this device in adults according to the British Hypertension Society (BHS) protocol and the International Protocol of the European Hypertension Society. METHODS: Ethical approval was obtained and participants gave written informed consent. Eighty-five participants who fulfilled the protocol criteria were recruited. Nine sequential same arm measurements were taken from each participant by two trained observers, comparing the device to mercury sphygmomanometery. Data analysis was performed according to the respective protocol guidelines. RESULTS: The device achieved an A grade for both systolic and diastolic pressures with 68, 91 and 98% of systolic and 73, 91 and 98% of diastolic differences within the 相似文献   

Ultra-small palladium nano-particles synthesized using bulky S/Se and N donor ligands as a stabilizer: application as catalysts for Suzuki–Miyaura coupling

Two chalcogenated ligands L1 and L2 containing anthracene core and amine functionality have been synthesized. Both the ligands have been characterized using ¹H and ¹³C{¹H} NMR techniques. The structure of L1 has also been corroborated by single crystal X-ray diffraction. Application of L1 and L2 as stabilizers for palladium nano-particles (NPs) has been explored and six different types of NPs 1–6 have been prepared by varying the quantity of stabilizer. The nano-particles have been characterized by PXRD, EDX, and HRTEM techniques. The size of NPs has been found to be in the range of ∼1–2 nm, 2–3 nm, 4–6 nm, 1–2 nm, 1–2 nm and 3–5 nm for 1–6 respectively. The catalytic activities of 1–6 have been explored for Suzuki–Miyaura coupling of phenyl boronic acid with various aryl halides. These NPs showed good catalytic activity for various aryl chlorides/bromides at low catalyst loading (5 mg). Among 1–6, the highest activity has been observed for NPs 1, probably due to their relatively small size and high uniformity in the dispersion. The recyclability of the NPs upto 5 catalytic cycles is a distinct advantage.

Fate of sputum samples transported in bottles containing cetylpyridinium chloride and sodium chloride: a national reference laboratory study

The transportation of sputum samples may sometimes take more than one week which results in an increased contamination rate and loss of positive cultures. The current study was planned to analyze the recovery rate of mycobacteria from transported samples with and without Cetylpyridinium chloride (CPC). Addition of CPC is useful for isolation of M. tuberculosis from sputum subjected to long-term storage.
