one of the main components of lung alveoli is surfactant. dppc (dipalmitolphosphatidylcholine) is thepredominant lipid component in lung surfactant that is responsible for lowering surface tension in alveoli in thisarticle. we used a very approximate model with computational method of ab initio to describe the interactionsbetween dppc as important component of lung surfactant and some chemical ...

Background: In Nigeria, the leaves of Manihot esculenta (Crantz) are eaten as vegetables. The leaves are rich in phytochemicals, valuable and natural sources of antioxidants, and are highly useful for human health and disease prevention. This study was aimed to evaluate the in vitro inhibitory effects of two extracts derived from the plant leaves on α-glucosidase and α-amylase. The total flavon...

Plants extracts has been used in traditional medicine for many years. The use of them has the least side effects in comprison to the synthetic drugs. The aim of this study was investigation and comparision of biological active components of Quercus persica and Quercus ilex. Sampling was done from Quercus persica and Quercus ilex stands. The antibacterial activity was assayed against Psuodomonas...

Objective: Little knowledge is available on the antimicrobial and antioxidant properties of Coccina grandis fruits and no study has reported on its cell proliferative property. The aim of this study was to examine the antimicrobial, antioxidant and cell proliferative property of fruits of C. grandis. Material and Methods: Fruits of C. grandis were extracted using water; ethanol and acetone by c...

This paper presents the experimental investigations conducted on a vertical closed loop pulsating heat pipe (VCLPHP) to evaluate the thermal performance. The values of thermal resistance and heat transfer coefficient obtained in the experimentation is used as evaluation parameters. The VCLPHP used has capillary tubes having an inner diameter of 2mm and outside diameter 3mm and bent into 5 turns...

PURPOSE This study compared the dentin collagen cross-linking potential of carbodiimide (EDC) prepared in three most commonly used solvents in dental adhesive systems: water, ethanol, and acetone. MATERIALS AND METHODS Thirty-eight extracted caries-free human permanent molars were used in this study. Demineralized dentin beams were prepared and cross linked by 0.3 M EDC in water, acetone, or ...

A device for the detection and determination of ethanol and acetone was constructed, consisting of a packed column, a chamber with a sensor head, 2 dc power supplies, a multimeter and a computer. A commercially available TGS 822 detector head (Figaro Company Limited) was used as the sensor head. The TGS 822 detector consists of a SnO2 thick film deposited on the surface of an alumina ceramic tu...

new approaches for treatment of infectious diseases in aquatic animals have important roles in aquaculture technology progress. in the present study, in vitro effects of different extracts of propolis, royal jelly and pollen obtained from beehives have been investigated on aquatic pathogenic bacterial isolates. the isolated bacteria identified on the basis of their biochemical properties and se...
