context hemorrhoidal disease is the most common anorectal disorder that requires surgical intervention. hemorrhoids require treatment when they result in symptoms such as bleeding or prolapse. surgical intervention is indicated for significant prolapse, and a number of accepted and viable methods are available for treating prolapsing hemorrhoids that do not reduce spontaneously (grade iii and i...

background dyes are one of the most important industrial pollutants, especially in textile industries. many methods have been proposed in order to remove color from wastewater among which, adsorption is more acceptable due to the ability for its use in the large scale. objectives the objective of this study was to investigate pumice as an inexpensive adsorbent for removal of methylene blue from...

to compare three various methods in the diagnosis of dentinal cracks formed in the apical third after root resection.one hundred extracted human maxillary central incisors were selected. the root canals were prepared with step-back technique. then 3mm from the apical end of all roots was cut perpendicular to the long axis of the tooth. the apical end of each root was evaluated to make sure ther...

introduction methylene blue was first described for the treatment of methemoglobinemia but practical usage of the compound for surgical purpose is common. the aim of this report is to describe a case of hemolysis in neonatal period as a potential hazard of methylene blue toxicity without presence of g6pd deficiency. case presentation in october 2015, a 36-week ga female infant with 2.05 kg weig...

Using a hand-held photoacoustic probe integrated with a clinical ultrasound array system, we successfully imaged objects deeply positioned in biological tissues. The optical contrasts were enhanced by methylene blue with a concentration of ~30 mM. The penetration depth reached ~5.2 cm in chicken breast tissue by using 650-nm wavelength, which is ~4.7 times the 1/e optical penetration depth. Thi...

objective: in order to overcome the limitation of systemic administration of methylene blue, this study investigated the encapsulation of methylene blue in polymeric liposomes and drug release following sonication. methods: we encapsulated methylene blue into nanoliposomes. the dynamic light scattering (dls) method was used to measure the size distribution of the liposomes. after loading methyl...

Background: Haemorrhoids are common perianal disease. Milligan-Morgan haemorrhoidectomy operation is a classical haemorrhoid resection procedure that has been widely used as gold standard. Classical associated with considerable postoperative pain. This leads to patient discomfort; prolonged hospital stays and increased cost. The causes of post pain multifactorial. Methylene blue biological dye....

One of the famous dyes is methylene blue (MB) which is a symbol of hazardous dyes. In this research, methylene blue was adsorbed using the blends of saffron petals with activated carbon. Five independent variables involving pH (2-13), contact time (5-270 min), saffron petals powder dosage (0.1-10 g/l), initial concentration of methylene blue solution (20-300 ppm) and activated carbon dosage (0....

methylene blue is widely used in various industrial branches. due to insufficient treatment, its occurrence in wastewater is frequently detected, which may result in serious environment problems to aquatic organisms. hydroponic experiments were conducted with rice seedlings (oryza sativa l. cv. xzx 45) exposed to methylene blue to determine the effective concentration using relative growth rate...

the reduction capacity of ammonia while present even at ppm level can be demonstrated by the increased encounter probability between ammonia and methylene blue dye (mb+) incorporated in nanomordenite and na-mor zeolites. the rate of reduction methylene blue dye by ammonia on the surface nanomordenite zeolite is faster than na-mordenite (na-mor) zeolite.because nanomordenite zeolite with high si...
