Research ArticleOpen accessIn the abstractApoptosis in Yeast is Modulated by Clove Leaf Extract and Eugenol Potentially by Interfering Caspase YCA1Septyani Amini, Rika Indri Astuti, Irmanida BatubaraApoptosis is a process of cell death important for preventing the development of diseases such as cancer, neurodegenerative disorders, autoimmune, and cardiovascular disease. Apoptosis is reported to be potentially induced by antioxidant compounds, including phytoextract. Thus in this study, we determined the potential of apoptotic modulation in yeast cells by clove extract, which was rich in eugenol. Apoptotic in yeast … …OnLine Journal of Biological Sciences, Vol. 22, Issue 3 · 15 Sep 2022 · 5,504 accessesView PDFCite
Research ArticleOpen accessIn the abstractNumerical Study of Natural Convection in a Square Porous Cavity Thermally Modulated on Both Side WallsGiovani E.B. Malomar, Abdoulaye Gueye, Cheikh Mbow et al.The numerical study of natural convection in a square porous cavity saturated by a Newtonian fluid is presented in this study. The vertical walls are subjected to temperatures varying sinusoidally in time and phase opposition while the upper and lower horizontal walls are thermally adiabatic. Darcy model is used, it is also assumed the fluid studied is incompressible and obeys … …American Journal of Engineering and Applied Sciences, Vol. 9, Issue 3 · 13 Aug 2016 · 7,917 accessesView PDFCite
Research ArticleOpen accessIn the abstractCpG Oligodeoxynucleotides Debate the Damaging Action of Cisplatin on Immune Cell DNA: A PCR Array Application on Repair Genes ExpressionNaglaa Fathy Alhusseini, Amal Abo El-Fadl, Shabaan Hemada et al.Synthetic Oligodeoxynucleotides (ODN) expressing CpG motifs (CpG-ODN) mimic the immunostimulatory activity of bacterial DNA and are commonly used to activate Toll Like Receptor 9 (TLR9) for therapeutic applications. CpG-ODN can counteract the activity of DNA-damaging chemotherapy and radiation therapy on immune cell and enhance immunity in preclinical mouse models. We hypothesized that these actions of CpG-ODN on immune cells are … …American Journal of Biochemistry and Biotechnology, Vol. 12, Issue 3 · 27 Jul 2016 · 7,628 accessesView PDFCite
EditorialOpen accessIn the abstractAre we Able to Harness the Immunomodulatory Power of Cytokines for Novel Autoimmune Disease Treatments?Giuseppe Nocentini, Graziella Migliorati, Carlo RiccardiSince the end of the 1970s, interleukin 2 (IL-2) has been known as a key player in T cell expansion/activation (Watson et al., 1980). In the late 1980s, some groups used IL-2 to stimulate the immune systems of tumour patients (Jacobs et al., 1986). The idea seemed brilliant and several attempts were made, but the results were disappointing (Lim et … …American Journal of Pharmacology and Toxicology, Vol. 10, Issue 2 · 22 Oct 2015 · 7,629 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffects of Unilateral Cervical Vagotomy on Murine Dendritic CellsDaniel Sanzio Gimenes da Cruz, Ana Paula Nascimento de Lima, Patrícia Benites Gonçalves da Silva et al.The cholinergic anti-inflammatory pathway has been demonstrated to be an important mechanism that modulates several inflammatory diseases. This modulation occurs upon activation of the vagus nerve, which modulates splenic macrophages and lymphocytes through the predominant neurotransmitter, Acetylcholine (ACh). We hypothesized that this modulation could also take place in dendritic cells, as these cells represent a link between the innate and … …American Journal of Immunology, Vol. 11, Issue 2 · 12 Jul 2015 · 6,949 accessesView PDFCite
Technical ReportOpen accessIn the abstractAnalysis of Low Probability of Intercept Radar Signals Using the Reassignment MethodDaniel L. Stevens, Stephanie A. SchuckersDigital intercept receivers are currently moving towards classical time-frequency analysis techniques for analyzing low probability of intercept radar signals. Although these techniques are an improvement over existing Fourier-based techniques, they still suffer from a lack of readability, due to poor time-frequency localization and cross-term interference, which may lead to inaccurate detection and parameter extraction. In this study, the reassignment method, … …American Journal of Engineering and Applied Sciences, Vol. 8, Issue 1 · 25 Mar 2015 · 7,215 accessesView PDFCite
Research ArticleOpen accessIn the abstractANALYSIS OF REDUCTION IN COMPLEXITY OF MULTIPLE INPUT- MULTIPLE OUTPUT-ORTHOGONAL FREQUENCY DIVISION MULTIPLEXING SYSTEMS WITH CARRIER FREQUENCY OFFSET ESTIMATION AND CORRECTIONSabitha Gauni, Kumar RamamoorthyOrthogonal Frequency Division Multiplexing (OFDM) is a promising research area in Wireless Communication for high data rates. The Multiple Input-Multiple Output (MIMO) technology when incorporated with the OFDM system promise a significant boost in the performance. But, the MIMO-OFDM systems are very sensitive to Carrier Frequency Offset (CFO) as it deteriorates the system performance with the rise of Inter-Carrier-Interference (ICI). … …Journal of Computer Science, Vol. 10, Issue 2 · 13 Nov 2013 · 6,791 accessesView PDFCite
Research ArticleOpen accessIn the abstractImmunological Response in Bovine Lymph Nodes Stimulated with Subunits VaccinesGabriel Andres Tafur Gomez, Marlene Isabel Vargas, Joaquin Hernan Patarroyo Salcedo et al.The vaccination process belongs to the public health intervention methodologies that help prevent infections. Vaccinations performed successfully in the history of medicine reported the significance of this procedure to increase the quality of life, prevent zoonoses and improve animal production. Vaccine emergence remained without exact rules for a long time, maintaining a close relationship with pathogens. However, subunit vaccines, with … …American Journal of Immunology, Vol. 9, Issue 2 · 20 Jun 2013 · 7,321 accessesView PDFCite
Research ArticleOpen accessIn the abstractBER Performance and Data Throughput of Sinusoidal Template-Based Impulse-Radio Ultra Wideband Receivers for Wireless Body Area NetworksMohamad Abou El-Nasr, Heba ShabanWindowed sinusoidal template-based correlator receivers are good candidates for high-data rate low-power Ultra Wideband (UWB) systems. Their performance approaches the performance of optimal detectors and provides low-power consumption. However, the ultra short pulses of UWB technology makes it sensitive to timing-errors. In this paper, the Bit-Error-Rate (BER) performance and maximum allowable data throughput of Equally-Correlated Pulse Position Modulation (EC-PPM) modulation … …American Journal of Applied Sciences, Vol. 10, Issue 5 · 30 May 2013 · 6,507 accessesView PDFCite
Research ArticleOpen accessIn the abstractMultiple-Input Multiple-Output Transmission Over a Multipath Faded ChannelsI.A.Z. QatawnehThe use of multiple antennas at the transmitter as well as at the receiver can greatly improve the capacity of a wireless link when operating in a rich scattering environment. In such an arrangement all transmitting antennas radiate in the same frequency band so the overall spectral efficiency becomes very high. Such a multiple antenna scheme, popularly known as Multiple … …American Journal of Applied Sciences, Vol. 10, Issue 3 · 11 Mar 2013 · 6,420 accessesView PDFCite
