25. Salivary glands of fetuses are adversely affected by artificial food colorings in rats
SUMMARY OBJECTIVE: Artificial food colorings, as types of food additives, are widely used at present in daily life. We aimed to investigate the effects of exposure to artificial food colorings during the intrauterine period on the salivary glands in adulthood. METHODS: A total of 30 Wistar albino female pregnant rats were included in this study. The treatm

26. Effects of Arf6 downregulation on biological characteristics of human prostate cancer cells
ABSTRACT Objective To evaluate the effects of Arf6 downregulation on human prostate cancer cells. Materials and Methods The effects of Arf6 downregulation on cell proliferation, migration, invasion and apoptosis were assessed by MTT, BrdU, scratch, Transwell assays and flow cytometry respectively. AKT, p-AKT, ERK1/2, p-ERK1/2 and Rac1 protein expressions

27. Blood microRNA expressions in patients with mild to moderate psoriasis and the relationship between microRNAs and psoriasis activity,
Abstract Background: In recent studies, microRNAs (mi-RNAs) have been shown to play an important role in psoriasis pathogenesis. However, studies evaluating mi-RNAs in the blood of psoriasis patients including a large number of mi-RNA panels are scarce. Objective: The authors aimed to assess mi-RNA expressions in blood samples of psoriasis patients, as wel

28. miRNA-1180 suppresses HCC cell activities via TRAF1/NF-κB signaling pathway
Abstract The miRNA-1180 anti-cancer effects in hepatocellular carcinoma cell were studied. 33 hepatocellular carcinoma patients were collected. In cancer and adjacent normal tissue from patients, TRAF1 protein and miR-1180 expression was determined by HE staining, IHC and RT-PCR methods. In the cell experiments, HepG2 cells were divided into three groups: NC

29. Multi-Step-Ahead Spectrum Prediction for Cognitive Radio in Fading Scenarios
Abstract This paper analyzes multi-step-ahead spectrum prediction for Cognitive Radio (CR) systems using several future states. A slot-based scenario is used, and prediction is based on the Support Vector Machine (SVM) algorithm. The aim is to determine whether multi-step-ahead spectrum prediction has gains in terms of reduced channel-switching and increased

30. Serologic strategy in detecting RHD altered alleles in Brazilian blood donors
ABSTRACT Background: We evaluated different technological approaches and anti-D clones to propose the most appropriate serologic strategy in detecting the largest numbers of D variants in blood donors. Methods: We selected 101 samples from Brazilian blood donors with different expressions of D in our donor routine. The tests were performed in immediate spi

32. The effect of facial expression on emotional contagion and product evaluation in print advertising
Abstract Purpose The purpose of this paper is to investigate the emotional contagion theory in print ads, and expand the literature of smiling to different type of smiles and gender congruency. Emotional contagion happens when an emotion is transferred from a sender to a receiver by the synchronization of emotions from the emitter. Drawing on emotional cont

33. L’ESPRIT SAINT SELON LES PERES DE L’ÉGLISE: DE LA THEOLOGIE PRENICEENNE AUX PREMIÈRES CONTROVERSES SUR LE FILIOQUE (2e– 8e SIECLES)
ABSTRACT The article shows the developments of pneumatology in the patristic era. These developments were already important in the 2nd and 3rd centuries. But reflection intensified especially during the 4th century, in the context of controversies with those who denied the divinity of the Holy Spirit. Athanasius and the Cappadocian Fathers made a major contr

34. Imaging evaluation of hallux valgus
Abstract This work investigates an alternative numerical scheme for the solution of an exact formulation based on Geometrical Optics (GO) principles to synthesize offset dual reflector antennas. The technique is suited to solve a second-order nonlinear partial differential equation of the Monge-Ampère type as a boundary value problem. An iterative algorithm

35. A Novel Tri-bandpass Filter Side-coupled Square Ring Based
Abstract This work presents the design of a tri-bandpass filter based on the side-coupled square ring structure. The modeling is conceived from the classic approach of coupled transmission lines. The geometry consists of a square structure of electrical length equal to twice the wavelength of the main operating frequency, and the laterally coupled lines thro
