Transcriptional Expression Profile of Toll Like Receptor 1 - 10 mRNA in Bovine Peripheral Mononuclear Cells in Response to Foot and Mouth Disease Antigens

Advances in Microbiology 2012年第4期2卷 417-425页

Toll like receptors are the primary component of innate immune response. The comparison of expression of innate immune genes TLR 1 - 10 was carried out by real time PCR by quantifying mRNA in bovine PBMCs. The bovine PBMCs in vitro stimulated with FMD infectious virus lead to up regulation of TLR 2, 3, 4 and down regulation of TLR 9. But stimulation with DNA vaccine carryingVP1 genes of FMDV leads to up regulation of TLR 2 only. Difference in the TLR gene expression by the virus and DNA vaccine, may be related to the outcome of the vaccine and carrier or persistent state of the animal which is seen in FMDV.

A novel diurnal and seasonal variation analysis of BTEX in Bengaluru urban area

Research in Cold and Arid Regions 2024年第1期16卷 14-19页

作者： H.N.sowmya M.Dinamani G.P.Shivashankara H.K.Ramaraju B.S.Surendra Vijaya V.Shanbhag R.Prajwal Department of Civil Engineering Dayananda Sagar College of EngineeringBangalore 560078India Department of Chemistry Dayananda Sagar College of EngineeringBangalore 560078India Department of Physics GFGCVijayanagarBengaluru 560040India

In the urban atmosphere of Bengaluru, various volatile organic compounds(VOCs), particularly Benzene,Toluene, Ethylbenzene, and Xylene(BTEX), have shown an increasing trend in concentration. The present research was conducted during summer and monsoon seasons, focusing on Kadubeesanahalli, a high-traffic area within the Bengaluru Metropolitan City. Hourly sample data was collected using a BTEX analyzer(Model GC955-600) and subsequently transformed into daily, monthly, and seasonal values. The study revealed distinct patterns in benzene concentrations. Benzene levels were lowest during the early morning hours, specifically from 1:00 *** 7:00 a.m.. Concentrations then increased from 7:00 a.m. to 9:00 a.m. and again from 4:00 p.m. to 11:00 p.m.,corresponding to the morning and evening peak traffic hours. However, between 10:00 a.m. and 4:00 p.m., the concentration decreased due to reduced traffic levels. These diurnal variations in benzene concentration are influenced by meteorological parameters. Comparing the two seasons, higher concentrations of Benzene, EthylBenzene, and MP-xylene were observed during the summer season. This increase is attributed to the elevated temperatures during summer, which promote the vaporization of BTEX compounds. Conversely, lower BTEX concentrations were recorded during the monsoon season due to the wet deposition process. The observed positive correlation(r > 0.5) among BTEX parameters strongly suggests a common source, most likely originating from vehicular emissions.

Plasticized Polymer Electrolyte Membranes Based on PEO/PVdF-HFP for Use as an Effective Electrolyte in Lithium-ion Batteries

引用

Chinese Journal of Polymer Science 2017年第3期35卷 407-421页

作者： pradeepa prabakaran ramesh prabhu manimuthu sowmya gurusamy edwinraj sebasthiyan school of physics alagappa universityKaraikudi-630 004Tamil NaduIndia

Plasticized polymer electrolytes were prepared using poly（ethylene oxide）(PEO)/poly（vinylidene fluoridehexafluoro propylene）(PVd F-HFP) with lithium perchlorate（Li Cl O4） and different plasticizers. XRD and FTIR spectroscopic techniques were used to characterize the structure and the complexation of plasticizer with the host polymer matrix. The role of interaction between polymer hosts and plasticizer on conductivity is discussed using the results of alternating current（a.c.） impedance studies. TG-DTA and SEM were used for thermal and physical characterizations. Maximum ionic conductivity(3.26 × 10;S·cm;) has been observed for ethylene carbonate（EC）-based polymer electrolytes. Electrochemical performance of the plasticized polymer electrolyte is evaluated in LiFePO;/plasticized polymer electrolytes（PPEs）/Li coin cell. Good performance with low capacity fading on charge discharge cycling is demonstrated.
