Objectives: Routine therapies cannot control refractory stable angina, leading to a high economic burden and an impaired quality of life. Persian medicine incorporates exceptional attention to lifestyle and nutrition to prevent and treat various diseases. Previous studies have reported the analgesic and anti-inflammatory effects of wet cupping. The present study aims to determine the effects of nutrition and cupping on refractory stable angina patients. Methods: Forty male patients with refractory stable angina were randomly allocated to four groups, including nutrition modification based on Persian medicine, wet cupping, nutrition modification along with wet cupping, and control. The primary outcomes were the changes in pain score using a visual analog scale and quality of life using the Seattle angina questionnaire. The secondary outcomes were changes in the exercise test and blood pressure. Results: The results of the present study revealed that 30 days of treatment with nutrition modification based on Persian medicine, cupping, and modified nutrition and cupping along with standard treatment for stable angina significantly increased the patient’s quality of life and exercise test results while reducing pain, and systolic and diastolic blood pressure. Conclusion: Applying complementary Persian medicine methods such as nutrition modification and cupping along with the classical medical treatments may improve outcomes for refractory stable angina patients.

Multilayered sheet metals have been widely used to achieve a wide range of favorable mechanical, physical, thermaland electrical properties. Laser beam irradiation over these materials creates extreme temperature changes thatcan lead to changes in the microstructural properties. Microstructure plays a very crucial role in determining themechanical property of the irradiated region, thus determining the optimum laser processing conditions. In thisstudy, metallographic studies, as well as tensile, fatigue and hardness tests, are undertaken on SUS430/C11000/SUS430 laminated composites that have been exposed to laser irradiation with different number of passes. Thiscomposite can be used in the microelectronics industry since it has the anti-corrosion and strength capability ofstainless steel, and the electrical superiority of copper. Ytterbium fiber laser is used in such a way that the governingmechanism of the process is the temperature gradient mechanism. Evolution of the microstructure is revealedby metallography, and the fracture levels of tension and fatigue test specimens are further evaluated by SEM. Thisstudy illustrates the significant effects of successive laser irradiation on the evolution of microstructure andmechanical properties, which lead to some suggestions for improving the properties of laser-formed SUS430/C11000/SUS430 composites.

In the Ultrafiltration (UF) region, the development of the membranes with ultra-water permeability andextraordinary oil rejection at the same time is highly desirable. Herein, a copolymer/nano-hybrid particlesmixed matrix membrane was fabricated with high hydrophilicity and oil-in-water separation performance,originating from the synergistic effect between the prepared copolymer and nanoparticles. Accordingly, atom transfer radical polymerization (ATRP) method, especially considered as a promisinggrafting technique to modify polyvinylidene fluoride (PVDF), was utilized for the synthesis of thePVDF-g-PMMA copolymer. Furthermore, two different nano-hybrid particles including graphene oxide(GO) sheets separately decorated with ZnO and SiO2 were also synthesized. Then, different membranecompositions with various GO@ZnO and GO@SiO2 contents were fabricated, and then, the synergisticeffect of each nano-hybrid particle with the PVDF-g-PMMA copolymer was evaluated. The preparedGO@ZnO and GO@SiO2 were used not only to modify ultrafiltration (UF) membranes for oil rejectionbut also to prevent protein BSA adsorption on the membrane surface based on their surface charge. The 4 wt.% PVDF-g-PMMA/0.3 wt.% GO@SiO2 and 4 wt.% PVDF-g-PMMA/0.3 wt.% GO@ZnO membranesprovided outstanding separation performance (soybean oil rejections of 93.4% and 95.2%, respectively)and ultra- water permeability (312 and 326 L/m2.h.bar, respectively). Based on the results in terms ofseparation and filtration performances, the M5 membrane exhibited more efficient performance thanM4 membrane. By increasing the amount of nano-hybrid particles, the overall finger-like voids, averagepore size, and surface roughness of membranes decreased, making them ideal for application in the watertreatment field. Also, the influence of hydrophilicity and charge density of GO@ZnO and GO@SiO2 nanohybridparticles with the copolymer in the PVDF membrane was examined through conducting theantifouling experiment in two different pH values, in which a great performance was also obtained. Compared to previous researches, GO@ZnO and GO@SiO2 nano-hybrid particles with the copolymer inthe PVDF membrane not only can generate ultra-high water permeability in low pressure but also provide>93% oil-in-water emulsion rejections.
