background and objectives: invasive and non-invasive techniques are used to diagnose h. pylori infection. some factors influence the choice of a diagnostic test, such as the sensitivity and specificity of the tests, the clinical circumstances and the cost-effectiveness of the testing strategy. the aim of this study was to reveal the relationship between different h. pylori infection diagnosis m...

PURPOSE Ultrasound therapy induces clinical healing of irradiated avascular mandibular bone and fractures. In vitro ultrasound in tissue culture has been shown to stimulate bone formation synthesis and bone remodeling factors and to stimulate osteoblast proliferation. Therefore, the aim of the present study was to investigate the effect of short-wave (1-MHz) and long-wave (45-kHz) ultrasound on...

In this study, we have determined the ability of the partial estrogen antagonists, clomiphene, tamoxifen, and nafoxidine, and the pure estrogen antagonists, ICI 164,384 and ICI 182,780, to inhibit angiogenesis in the chick egg chorioallantoic membrane. All of the partial estrogen antagonists and the pure estrogen antagonist, ICI 182,780, showed significant angiostatic activity in a dose-related...

Chicks that hatch from eggs containing group specific antigen (gs antigen) of lymphoid leukosis virus (LLV) subgroups, grow poorly. In our laboratory for more precise identification of LLV-of subgroup A (LLV-A) resistant and susceptible genotypes by progeny testing, the chorioallantoic membrane (CAM) assay in complemented by liver tumour (LT) assay, wherein Rous sarcoma virus (RSV) of subgroup ...

This study was designed to evaluate efficacy of polyherbal hypocholesterolemic supplement AV/HLP/16 (test compound) on serum and egg yolk cholesterol levels and egg quality parameters in layers. One hundred and twenty healthy White Leghorn (BV 300 strain) of 54 weeks age were randomly divided into four treatments (T 0 , T 1 , T 2 , T 3 ); subdivided into three replicates with ten birds in each ...

[1] Recent modeling results have raised doubts about the ability to deglaciate from a global glaciation at atmospheric carbon dioxide levels that are realistic for a Neoproterozoic Snowball Earth. Here we argue that over the lifetime of a Snowball event, ice dynamics should lead to the development of a layer of continental and volcanic dust at the ice surface in the tropics that would significa...

Phlomis linearis Boiss. & Bal. of the Lamiaceae family growing in central, east and southeast Anatolia is an endemic species for Turkey. The essential oil obtained from the aerial parts by hydro distillation was subsequently analyzed by GC/MS. The main components of the oil were found as beta-caryophyllene (24.2%), germacrene D (22.3%) and caryophyllene oxide (9.2%), among 49 identified compoun...
