The phase change material is a hot research topic in solar thermal storage systems. However, the conductivity of pure materials usually low, which hinders its application facilities. In this study, copper foam used to increase characteristics paraffin. Simulations are conducted compare melting paraffin and paraffin/copper composite material. A visualized experimental device was designed built, ...
In this paper we present a simple and rapid method of modifying poly(dimethylsiloxane) (PDMS) surfaces with paraffin wax. PDMS that contains a layer of paraffin wax at its surface resists the absorption of hydrophobic molecules; we used fluorescence microscopy to confirm that paraffin-modified PDMS resists the absorption of rhodamine B. Furthermore, we demonstrated that microfluidic devices mad...
Background and purpose: Wound is a type of injury with high prevalence in the society. The main requirement for wound management is rapid and complete wound healing without the spread of infection. Medicinal plants are affordable and accessible and suggested as one of the key treatment options. The aim of this study was to investigate the effect of lipogel formulations containing the extract...
Background: In 10-30% of the cases with sarcoidosis, skin lesions appear solely without any systemic signs or symptoms. BTNL2 gene, which is a member of the immunoglobulin gene super family and is associated with CD86 and CD80 co-stimulatory receptors, is identified to play an important role in the establishment of sarcoidosis. We aimed to evaluate the role of this gene in patients with skin sa...
Background Constipation is one of the most common disorders in children. The purpose of this study was to compare paraffin and polyethylene glycol (PEG) in the treatment of children with chronic constipation. Materials and Methods This study is a double-blind randomized trial. Total 160 children aged 2-12 years old with chronic constipation attending the pediatric clinic of Mousavi Hospital in ...
Background & Aims: Leukoplakia is the most common premalignant or potentially malignant lesion of the oral mucosa and its potentiality for malignant transformation is unpredictable. The aim of the present study was to evaluate p53 expression in normal oral epithelium, leukoplakia and oral squamous cell carcinoma. Methods: The standard Biotin streptavaidin peroxidase immunohistochemical staining...
