| 2 | Non-timber forest products and their contribution to households income around Falgore Game Reserve in Kano, Nigeria显示文摘Introduction:In the recent decades,there has been growing interest in the contribution of non-timber forest products(NTFPs)to livelihoods,development,and poverty alleviation among the rural populace.This has been prompted by the fact that communities living adjacent to forest reserves rely to a great extent on the NTFPs for their livelihoods,and therefore any effort to conserve such resources should as a prerequisite understand how the host communities interact with them.Methods:Multistage sampling technique was used for the study.A representative sample of 400 households was used to explore the utilization of NTFPs and their contribution to households’income in communities proximate to Falgore Game Reserve(FGR)in Kano State,Nigeria.Descriptive statistics and logistic regression analysis were used to analyze and summarize the data collected.Results:The findings reveal that communities proximate to FGR mostly rely on the reserve for firewood,medicinal herbs,fodder,and fruit nuts for household use and sales.Income from NTFPs accounts for 20–60%of the total income of most(68%)of the sampled households.The utilization of NTFPs was significantly influenced by age,sex,household size,main occupation,distance to forest and market.Conclusions:The findings suggest that NTFPs play an important role in supporting livelihoods,and therefore provide an important safety net for households throughout the year particularly during periods of hardship occasioned by drought.It is suggested that stakeholders should prioritize technical and financial support programs on agricultural value addition and handcrafts that would promote off-farm income generating activities,in addition,provision of alternative domestic cooking energy such as biogas in communities proximate to FGR in order to reduce pressure relating to fuelwood gathering from the forest,this will help to improve forest resources quality. | Muhammad Sabiu Suleiman Vivian Oliver Wasonga Judith Syombua Mbau Aminu Suleiman Yazan Ahmed Elhadi | 2017 | Ecological Processes2017,6,1: | 5 |
| 3 | The frequency and antimicrobial resistance patterns of nosocomial pathogens recovered from cancer patients and hospital environments显示文摘Objective:To determine the prevalence and antimicrobial resistance rates of nosocomial pathogens isolated from cancer patients and hospital environments.Methods:A descriptive cross-sectional study was conducted between December 2010 to May 2013 at Radiation and Isotopes Centre of Khartoum,Sudan.A total of 1 503 samples(505 clinical and 998 environmental)were examined.Isolates were identified,and their antimicrobial susceptibility was determined using standard laboratory procedures.Results:Out of 505 clinical samples,nosocomial pathogens were found as 48.1%.Among hospital environment samples,bacterial contaminants were detected in 29.7%of samples.The main microorganisms recovered from cancer patients were Proteus spp.(23.5%),Escherichia coli(22.2%),Pseudomonas aeruginosa(P.aeruginosa)(21.0%)and Staphylococcus aureus(20.2%).The most frequent isolates from hospital environments were Bacillus spp.(50.0%),Staphylococcus aureus(14.2%)and P.aeruginosa(11.5%).The proportions of resistance among Gram-negative pathogens from cancer patients were high for ampicillin,cefotaxime,ceftazidime and ceftriaxone.Moderate resistance rates were recorded to ciprofloxacin,such as 51.0%for P.aeruginosa,21.7%for Klebsiella pneumoniae and 55.5%for Escherichia coli.Except Klebsiella,there were no significant differences(P0.05)of resistance rates between Gram-negative isolates from cancer patients to those from the hospital environments.The proportions of extended-spectrum b-lactamase producing isolates from cancer patients were not differ significantly(P=0.763)from those collected from the hospital environments(49.2%;91/185 vs.47%;32/68).Conclusions:The prevalence of nosocomial infection among cancer patients was high(48.1%)with the increasing of antimicrobial resistance rates.Hospital environments are potential reservoirs for nosocomial infections,which calls for intervention program to reduce environmental transmission of pathogens. | Aymen Mudawe Nurain Naser Eldin Bilal Mutasim Elhadi Ibrahim | 2015 | Asian Pacific Journal of Tropical Biomedicine2015,5,12: | 4 |

The TNFα-G308 A region was amplified by PCR and the different genotypes were detected by restriction fragment length polymorphism analysis. The TNFα protein was detected by enzyme-linked immunosorbent assay. The influence of different TNFα-G308 A genotypes on TNFα expression and liver disease progression were statistically analyzed. The OR and 95%CI were calculated to assess the relative risk confidence.RESULTS Current data showed that the TNFα-G308 A SNP frequency was significantly different between controls and HCV infected patients(P = 0.001). Both the AA genotype and A allele were significantly higher in late fibrosis patients(F2-F4,n = 60) than in early fibrosis patients(F0-F1,n = 60)(P = 0.05,0.04 respectively). Moreover,the GA or AA genotypes increased the TNFα serum level greater than the GG genotype(P = 0.002). The results showed a clear association between severe liver pathological conditions(inflammation,steatosis and fibrosis) and(GA + AA) genotypes(P = 0.035,0.03,0.04 respectively). The stepwise logistic regression analysis showed that the TNFα genotypes(GA + AA) were significantly associated with liver inflammation(OR = 3.776,95%CI: 1.399-10.194,P = 0.009),severe steatosis(OR = 4.49,95%CI: 1.441-14.0,P = 0.010) and fibrosis progression(OR = 2.84,95%CI: 1.080-7.472,P = 0.034). Also,the A allele was an independent risk factor for liver inflammation(P = 0.003),steatosis(P = 0.003) and fibrosis(P = 0.014). CONCLUSION TNFα SNP at nucleotide-308 represents an important genetic marker that can be used for the prognosis of different liver pathological changes in HCV infected | Noha G Bader El Din Sally Farouk Reem El-Shenawy Marwa K Ibrahim Reham M Dawood Mostafa M Elhady Ahmed M Salem Naglaa Zayed Ahmed Khairy Mostafa K El Awady | 2016 | World Journal of Gastroenterology2016,22,34: | 3 |

| 14 | Performance analysis of SBAS ephemeris corrections and integrity algorithms in China region显示文摘Satellite Based Augmentation Systems(SBASs)improve the positioning accuracy and integrity by broadcasting to the civil aviation community the corrections and integrity parameters.A snapshot algorithm based on the minimum variance estimation is investigated in this study to calculate the satellite clock and orbit corrections.A chi-square test is performed on the remaining errors in the corrected ephemeris to guarantee the integrity.User Differential Range Error(UDRE)and scaling matrix contained in Message Type 28 are derived using the covariance information based on the assumption that one of the reference stations failed.A software package is developed and applied in the real data collected at 26 stations.International GNSS(Global Navigation Satellite System)Service(IGS)precise clock and orbit products are taken as the references to assess the accuracy of corrections.For both Global Positioning System(GPS)and BeiDou Navigation Satellite System(BDS),the range accuracy of 0.10 m can be achieved with the employment of the derived corrections.No obvious performance difference between GPS and BDS is found.UDREs for all visible satellites are generated with the maximum index of 12 and minimum index of 3.The geometric range differences calculated with IGS precise products and broadcast ephemeris are employed to assess the integrity of UDRE.It is found that the UDRE is able to bound the residuals with 99.9%confidence which meet the requirement of aviation users.With ionospheric delay corrected by Global Ionosphere Map(GIM),the positioning accuracy of 0.98 m with GPS corrections and 0.80 m with multi-constellation augmentation can be achieved which indicates a significant improvement of GPS standalone results. | Biao Jin Shanshan Chen Dongjun Li Yuechen Wang Elhadi Takka | 2021 | Satellite Navigation2021,2,1: | 1 |
