| 3 | In vitro interference of cefotaxime at subinhibitory concentrations on biofilm formation by nontypeable Haemophilus influenzae显示文摘Objective:To investigate the in vitro interference of cefotaxime at subinhibitory concentrations [sub-minimal inhibitory concentrations(MIC)] on biofilm formation by nontypeable Haemophilus influenzae(NTHi).Methods:The interference of subinhibitory concentrations of cefotaxime on biofilm formation of the clinical strong-biofilm forming isolates of NTHi was evaluated by a microtiter plate biofilm formation assay.The effect of sub-MIC cefotaxime on bacterial cell-surface hydrophobicity was determined using a standard microbial adhesion to n-hexadecane test.Additionally,the effects on bacterial adherence to human fibronectin and expression of bacterial adhesins were also investigated.Results:Subinhibitory concentrations of cefotaxime,both at 0.1× and 0.5× MIC levels,efficiently reduced the NTHi biofilm formation,and this effect was independent of decreasing bacterial viability.Sub-MIC cefotaxime also decreased bacterial cell-surface hydrophobicity and reduced adherence to human fibronectin.Inhibition in the P2 and P6 gene expressions upon exposure to sub-MIC cefotaxime was also noted.Conclusions:Taken together,our results indicate that sub-MIC cefotaxime interferes with the formation of NTHi biofilm,and this effect is feasibly related to the interference with cell-surface hydrophobicity,fibronectin-binding activity as well as alteration of the P2 and P6 gene expression.The findings of the present study therefore provide a rationale for the use of subinhibitory concentrations of cefotaxime for treatment of NTHi-related diseases. | Sudarat Baothong Sutthirat Sitthisak Duangkamol Kunthalert | 2016 | Asian Pacific Journal of Tropical Biomedicine2016，6，9： | 1 |

| 7 | Estimating the Great Lakes net radiation using satellite remote sensing and MERRA reanalysis显示文摘The net all-wave radiation of the Great Lakes(GL)is a key to understanding the effects of climate change on the GL.There is a high possibility of underestimating the net all-wave radiation of the GL when using existing methodologies with inputs from near-shore and land-based meteorological data.This study provides the first technique to estimate net all-wave radiation over the GL from July 2001 to December 2014 using a combination of data from satellite remote sensing,reanalysis data sets,and direct measurements.The components of the surface radiation budget estimated from the proposed method showed good statistical agreement.The instantaneous net radiation estimated by our methods was compared with the in situ measurements from June 2008 to April 2012(Stannard Rock Lighthouse:SR)and September 2009–April 2011(Spectacle Reef Lighthouse:SP).The comparisons from SR and SP also showed strong statistic agreement(R^(2)=0.74 and 0.7;RMSE=9.26 and 10.60 W m^(−2) respectively).Monthly spatial variations of net shortwave radiation varied with cloud cover and surface albedo while net longwave radiation varied with the temperature difference between the water surface and the atmosphere. | Sitthisak Moukomla Peter D.Blanken | 2017 | International Journal of Digital Earth2017，10，8： | 0 |
| 8 | Emergence of staphylococcal cassette chromosome mec type Ⅰ with high-level mupirocin resistance among methicillin-resistant Staphylococcus aureus显示文摘Objective: To investigate the molecular epidemiology and antimicrobial resistance patterns of methicillin-resistant Staphylococcus aureus(MRSA) among healthcare workers and patients.Methods: MRSA isolates were recovered from nasal swabs collected at a tertiary care hospital of Nepal and confirmed on the basis of Gram staining, conventional biochemical tests, and PCR amplification of mec A gene. PCRs were also used for detection of the different resistance genes and staphylococcal cassette chromosome(SCC) mec types.Antibiotic susceptibility patterns of isolates were assessed by disc diffusion method and minimum inhibitory concentrations were determined by E-test.Results: A total of 29 MRSA were isolated from 536 nasal swabs(5.4%) of health care workers and patients at a tertiary care hospital in Nepal. All isolates were susceptible to amikacin, gentamicin, vancomycin(minimal inhibitory concentrations < 2 mg/m L), tigecycline, tetracycline, nitrofurantoin, rifampicin, quinupristin-dalfopristin, and linezolid. Among the 29 MRSA isolates, resistance to erythromycin(72%), ciprofloxacin(75%), co-trimoxazole(62%), clindamycin(10%), and chloramphenicol(10%) was found, and fifteen isolates(51%)exhibited high-level mupirocin resistance(minimal inhibitory concentrations > 1 024 mg/m L).Fourteen isolates were found harboring the mup A gene and one isolate was found carrying the novel mup B gene. High prevalence(68%) of SCCmec I type was found, followed by SCCmec V(13%) and SCCmec III(3%) among all the MRSA isolates.Conclusions: We found the emergence of SCCmec type I with high-level mupirocin resistance among MRSA in Nepal. Data also suggest that MRSA SCCmec type V strain has spread from the community to the hospital. | Prabhu Raj Joshi Mahesh Acharya Rajan Aryal Kamal Thapa Trishna Kakshapati Rathanin Seng Anjana Singh Sutthirat Sitthisak | 2017 | Asian Pacific Journal of Tropical Biomedicine2017，7，3： | 0 |
