Mastic oil from Pistacia lentiscus variation chia, a natural combination of bioactive terpenes, has been shown to exert anti-tumor growth effects against a broad spectrum of cancers including mouse Lewis lung adenocarcinomas (LLC). However, no studies have addressed its anti-metastatic actions. In this study, we showed that treatment of LLC cells with mastic oil within a range of non-toxic conc...

To solve the problem of rutting and fatigue damage to asphalt pavement, rutting and fatigue performances of Qingchuan rock asphalt modified asphalt were studied, based on the dynamic shear rheometer test, the dynamic creep test, the rutting test, the indirect tensile fatigue test, the small-sized acceleration loading test, the compressive resilient modulus test, the BISAR3.0 Program and the rut...

The conventional French fatigue test has yielded significantly different results for two asphalt materials with the same grade of pure asphalt. A research program was begun to study the influence of the asphalt nature on the fatigue behavior of asphalt materials. The program included full-scale experimentation on the circular test track of the Laboratoire Central des Ponts et Chaussees, laborat...

BACKGROUND AND AIM: Hyposalivation can cause many difficulties for patients like opportunistic infections such as candidiasis, mouth sores, and dysphagia as well as reduced quality of life (QOL). Methods such as using sugar-free chewing gum are recommended to treat this complication. Mastic is a natural substance and since it has various properties in addition ...

In road paving industry, asphalt emulsion is used for cold mix application such as chip seal, slurry seal, microsurfacing, cold recycled mixture and etc. Asphalt emulsion has several advantages compared to normal asphalt such as eco-friendly, easy to handle at ambient temperature and energy saving material because it does not need any heating process in its application. The history of asphalt e...

BACKGROUND Most previous mastic investigators have not considered its potent cytotoxicity that may significantly affect the interpretation of obtained data. In the present study, we re-evaluated several biological activities of mastic extracts, based on chemotherapeutic indexes. MATERIALS AND METHODS Pulverized mastic gum was extracted with n-hexane and then with ethyl acetate or independentl...

BACKGROUND This study aimed to compare the burst strength of suture closure versus the use of suture and strip together. METHODS On cadavers, 50 skin incisions were closed as follows: group 1--subcuticular continuous suture; group 2--same suturing with placement of strips; group 3--same as group 2 except gum mastic was applied prior to strips; group 4--strips alone; and group 5--strips with g...

γ-(2,3-Epoxypropoxy)propyltrimethoxy silane surface modified layered double hydroxides (KH560-LDHs) were prepared and used to improve the ultraviolet ageing resistance of asphalt. The results of X-ray photoelectron spectrometry (XPS) indicated that KH560 has been successfully grafted onto the surface of LDHs. The agglomeration of LDHs particles notably reduced after KH560 surface modification a...

Stone mastic asphalt (SMA) has been widely used in Europe since the early 1960s, followed by numberous trials countries such as USA and Australia, where it positioned a premium pavement surfacing course purposely for heavy duty pavements, highways other roads with truck traffic. In addition, Malaysia's demand 900 million eggs per month produces significant amount of solid waste. If all these eg...
