Accumulating evidence suggests that the androgen receptor (AR) may play an important role in the development and progression of prostate cancer. To find new, useful compounds that effectively may attenuate the function of AR in prostate cancer cells, the authors investigated the effect of gum mastic, a natural resin, on AR activity. An androgen-responsive prostate cancer cell line LNCaP was use...

Methods of preparing test specimens in laboratories are particularly important. It also holds true in terms of compaction procedure in predicting pavement performance. The currently available laboratory compactor cannot adequately replicate field compaction conditions, especially the Stone Mastic Asphalt (SMA) mixture. The essential element of SMA mixture comprises of stones that are placed nex...

in the recent years, herbal oral hygiene products have gained increasing attention. the aim of this study was to assess the effects of three types of mastic gums on the level of mutans streptococci, lactobacilli and ph of the saliva.forty-two students in the age range of 20-30 years were divided into three parallel groups; each of them separately used pure mastic gum, xylitol mastic gum and pro...

Incorporating fibers into asphalt mixtures as additives and stabilizers can significantly enhance the performance of pavements. This study aimed to analyze impact using basalt bamboo modifiers on properties mastics. The effects different types rutting resistance, fatigue elastic recovery, low-temperature cracking were tested frequency scanning, linear amplitude scanning (LAS), multiple stress c...
