objective(s): in the current study, sunscreen and moisturizing properties of solid lipid nanoparticle (sln)-safranal formulations were evaluated. materials and methods:series of sln were prepared using glyceryl monostearate, tween 80 and different amounts of safranal by high shear homogenization, and ultrasound and high-pressure homogenization (hph) methods. sln formulations were characterized ...

BACKGROUND An outbreak of severe nosocomial Burkholderia cepacia infections in patients admitted to intensive care unit (ICU), including investigation of the reservoir, is described. METHODS Over a period of 18 days, isolates of Burkholderia cepacia were recovered from different biological samples from five patients who were admitted to a multidisciplinary 18-bed intensive care unit. Isolatio...

the objective of this study was to investigate the effects of saffron as a natural sunscreen and moisturizer. the pollens of the saffron were dried and powdered in a grinder. the experimental formulations included a homosalate (8%) lotion reference, lotions with 2, 4 and 8% of grinded saffron, and the control lotion base without saffron. the lotions containing saffron were prepared like homosal...

OBJECTIVES In the current study, sunscreen and moisturizing properties of solid lipid nanoparticle (SLN)-safranal formulations were evaluated. MATERIALS AND METHODS Series of SLN were prepared using glyceryl monostearate, Tween 80 and different amounts of safranal by high shear homogenization, and ultrasound and high-pressure homogenization (HPH) methods. SLN formulations were characterized f...

OBJECTIVES This work aimed to design, synthesize and characterize replacement natural moisturizing factor (NMF) composed of modified hygroscopic linear amino acids to pre-empt or repair skin barrier dysfunction. METHODS Following synthesis and characterization, thermo-gravimetric analysis and quantum mechanics molecular modelling quantified and depicted water binding to the new compounds. Del...

BACKGROUND During mechanical ventilation effective conditioning of inspired air is important. In this respect, conventional humidifiers do not perform optimally. By design, a counter-flow-type humidifier should improve humidification and heating, but may increase resistance. METHODS We investigated mechanical impedance and work of breathing (using pressure-flow characteristics and additional ...

BACKGROUND Tretinoin is considered the benchmark prescription topical therapy for improving fine facial wrinkles, but skin tolerance issues can affect patient compliance. In contrast, cosmetic antiwrinkle products are well tolerated but are generally presumed to be less efficacious than tretinoin. OBJECTIVES To compare the efficacy of a cosmetic moisturizer regimen vs. a prescription regimen ...

Hypertension is a major risk factor for the cardiovascular diseases. One of the factors contributing to blood pressure is peripheral vascular resistance. Vascular stiffness plays a key role in developing the hypertension, leading to increased systolic blood pressure and pulse pressure. from Avicenna s perspective, the blood pressure caused by 1- Increased blood volume 2- Warm heart dystemperame...
