purpose: ‏to determine the visual and anatomic outcomes of epikeratoplasty in 7 eyes of 6 patients with keratoglobus. method: in a retrospective interventional case series, seven eyes of six patients with keratoglaobus (kgb) aged 5 to 39 years underwent epikeratoplasty. three patients (3 eyes) had blue sclera, hypermobile joints, and consanguineous parents and 3 patients (4 eyes) had only kgb. ...

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...

Effects of four cooking methods (microwave cooking, grilling, steaming and shallow fat frying) and reheating by microwave on volatile profile in S. commerson were evaluated. Thirty compounds were identified in GC-MS analysis of raw samples. The number of volatile compounds had increased to 36, 46, 45 and 45 compounds in microwave cooked, grilled, steamed and shallow fat fried samples, respectiv...

Effects of 1-methylcyclopropene (1-MCP), 2-chloroethyl phosphonic acid (ethephon), and methyl jasmonate (MeJA) on production of aroma volatile compounds and ethylene by ‘Delicious’ and ‘Golden Delicious’ apples [Malus sylvestris (L.) Mill. var. domestica (Borkh.) Mansf.] during ripening were investigated. Forty-four volatile compounds in ‘Delicious’ and 40 compounds in ‘Golden Delicious’ were d...

one of the most important methods to produce sponge iron is coal based reduction of iron ore. direct reduction methods based on coal are being improved due to the abundance of coal sources and its lower cost in comparison with natural gas. volatile materials in coal play an important role in the reduction of iron oxides. in this study, noncoking coal with high volatile materials from iran and c...

Demodex is a type of permanent obligatory parasite, which can be found on the human body surface. Currently, drugs targeting Demodex usually result in adverse effects and have a poor therapeutic effect. Thus, the aim of the present study was to investigate the use of Chinese crude medicine volatile oils for targeting and inhibiting Demodex in vitro. The volatile oils of six Chinese crude medici...

Carbon adsorbents for use in the removal of gaseous toluene from air were prepared buckwheat (Fagopyrum esculentum Moench) hull. A chemically-activated adsorbent was via impregnation raw hull powder with potassium carbonate, followed by thermal decomposition. The exhibited improved adsorption capacity compared to without chemical activation. Toluene concentration decreased 220 ppm 160 during 24...

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...

Bulk chondritic meteorites and terrestrial planets show a monotonic depletion in moderately volatile and volatile elements relative to the Sun's photosphere and CI carbonaceous chondrites. Although volatile depletion was the most fundamental chemical process affecting the inner solar nebula, debate continues as to its cause. Carbonaceous chondrites are the most primitive rocks available to us, ...
