Cardiometabolic risk factors trend in Iranian adults with hypertension over 15 years: findings of nationwide steps of 2007-2021.

Objectives: People with hypertension are more susceptible to developing cardiometabolic risk factors including overweight, obesity, diabetes mellitus, dyslipidemia, and metabolic syndrome (MetS). We aim to determine the trends in the prevalence of these risk factors among Iranian adults with hypertension from 2007 to 2021.

Methods: We utilized data for adults from 25 to 64 years old from four rounds of the STEPwise approach to non-communicable diseases risk factor surveillance (STEPS) study conducted in Iran in 2007, 2011, 2016, and 2021.

Synthesis, characterization, and nonlinear optical properties of copper (II) ligand Schiff base complexes derived from 3-Nitrobenzohydrazide and benzyl.

A new series of Cu (II) complexes were prepared using Schiff base ligand of N-N'-(1,2-diphenyl ethane-1,2-diylidene)bis(3-Nitrobenzohydrazide). The prepared ligand and Cu (II) complex were characterized using various physicochemical investigations such as X-ray diffraction (XRD), Field emission scanning electron microscopy (FESEM), and Energy dispersive X-ray analysis (EDX), Fourier Transform Infrared (FT-IR), [Formula: see text] Nuclear Magnetic Resonance (NMR), [Formula: see text] NMR, Diffuse Reflectance Spectroscopy (DRS), Vibrating Sample Magnetometer (VSM), and Z-Scan technique (Nonlinear optical (NLO) properties). In addition, the prepared samples have been examined for their NLO characteristics with the help of the Density Functional Theory calculations which proved that the Cu (II) Complex is more polarized than Ligand.

Well-aligned nano-fiberous membranes based on three-pole electrospinning with channel electrode.

Three-pole electrospinning devices integrated with a blade-cage collector were developed to fabricate well-aligned nano-fiberous membranes. The proposed three-pole configuration with a channel electrode can be a powerful tool in aligning nano-fibers with regular diameter because the generated electric field can be accurately controlled without severe fluctuation in comparison with other methods. The three-pole electrospinning method is also valid for industrial mass production and accurate diameter control of the aligned nano-fibers.
