1Prevalence and risk factors associated with malaria infection among pregnant women in a semi-urban community of north-western Nigeria显示文摘Background:Malaria during pregnancy remains a serious public health problem,with substantial risks for the mother,her foetus and the newborn.The aim of this study was to determine the prevalence of malaria and possible risk factors for malaria infection among pregnant women in a semi-urban area in north-western Nigeria.Pregnant women are among the most susceptible to malaria infection.Knowledge of their malaria infection status is an important yardstick to measure the effectiveness of any malaria control programme.Methods:We conducted a cross sectional study in the semi-urban area of Argungu,Kebbi State Nigeria.Two hundred and fifty five pregnant women were included in the study after informed verbal consent was obtained.For each participant,the socio-demographic profile,stage of pregnancy and attitude to the use of insecticide-treated nets(ITNs)were investigated using a questionnaire.Peripheral blood samples were collected and thick blood smears were prepared and stained with Giemsa stains to check for malaria parasitaemia.The associations between age,education level and use of ITNs with occurrence of malaria infection during pregnancy were analysed using the chi-square test.Results:One hundred and six(41.6%)out of 255 pregnant women were infected with malaria parasites,with a mean parasite density of 800 parasitesμl−1.It was found that prevalence and parasite density decreased as age increased.The chi-square test indicated that a lack of education and non-usage of ITNs were significantly associated with malaria infection.Conclusion:Malaria is still a major public health issue among pregnant women mainly due to illiteracy and non-compliance to using ITNs.Increasing awareness about malaria preventive measures and early attendance of antenatal care services will help to reduce malaria and,consequently,its associated morbidities and mortalities.Sani Abdullahi Fana Mohammed Danladi Abubakar Bunza Sule Aliyu Anka Asiya Umar Imam Shehu Usman Nataala 2015Infectious Diseases of Poverty2015,4,1:4

4Food contamination as a pathway for lead exposure in children during the 2010–2013 lead poisoning epidemic in Zamfara,Nigeria显示文摘In 2010, an estimated 400 to 500 children died of acute lead poisoning associated with artisanal gold mining in Zamfara, Nigeria. Processing of gold ores containing up to 10% lead within residential compounds put residents, especially children, at the highest risk. Principal routes of exposure were incidental ingestion and inhalation of contaminated soil and dusts. Several Nigerian and international health organizations collaborated to reduce lead exposures through environmental remediation and medical treatment. The contribution of contaminated food to total lead exposure was assessed during the environmental health response. Objectives of this investigation were to assess the influence of cultural/dietary habits on lead exposure pathways and estimate the contribution of contaminated food to children's blood lead levels(BLLs). A survey of village dietary practices and staple food lead content was conducted to determine dietary composition, caloric intakes, and lead intake. Potential blood lead increments were estimated using bio-kinetic modeling techniques. Most dietary lead exposure was associated with contamination of staple cereal grains and legumes during post-harvest processing and preparation in contaminated homes. Average post-harvest and processed cereal grain lead levels were 0.32 mg/kg and 0.85 mg/kg dry weight, respectively. Age-specific food lead intake ranged from 7 to 78 μg/day. Lead ingestion and absorption were likely aggravated by the dusty environment, fasting between meals, and nutritional deficiencies. Contamination of staple cereal grains by highly bioavailable pulverized ores could account for as much as 11%–34% of children's BLLs during the epidemic, and were a continuing source after residential soil remediation until stored grain inventories were exhausted.Simba Tirima Casey Bartrem Ian von Lindern Margrit von Braun Douglas Lind Shehu Mohamed Anka Aishat Abdullahi 2018Journal of Environmental Sciences2018,30,5:2
5Resonance-enhanced multi-octave supercontinuum generation in antiresonant hollow-core fibers显示文摘Ultrafast supercontinuum generation in gas-filled waveguides is an enabling technology for many intriguing applications ranging from attosecond metrology towards biophotonics,with the amount of spectral broadening crucially depending on the pulse dispersion of the propagating mode.In this study,we show that structural resonances in a gas-filled antiresonant hollow core optical fiber provide an additional degree of freedom in dispersion engineering,which enables the generation of more than three octaves of broadband light that ranges from deep UV wavelengths to near infrared.Our observation relies on the introduction of a geometric-induced resonance in the spectral vicinity of the ultrafast pump laser,outperforming gas dispersion and yielding a unique dispersion profile independent of core size,which is highly relevant for scaling input powers.Using a krypton-filled fiber,we observe spectral broadening from 200 nm to 1.7μm at an output energy of B 23μJ within a single optical mode across the entire spectral bandwidth.Simulations show that the frequency generation results from an accelerated fission process of solitonlike waveforms in a non-adiabatic dispersion regime associated with the emission of multiple phase-matched Cherenkov radiations on both sides of the resonance.This effect,along with the dispersion tuning and scaling capabilities of the fiber geometry,enables coherent ultra-broadband and high-energy sources,which range from the UV to the mid‐infrared spectral range.Rudrakant Sollapur Daniil Kartashov Michael Zürch Andreas Hoffmann Teodora Grigorova Gregor Sauer Alexander Hartung Anka Schwuchow Joerg Bierlich Jens Kobelke Mario Chemnitz Markus A Schmidt Christian Spielmann 2017Light(Science & Applications)2017,6,1:2

19SARS-CoV-2 spike protein and RNA dependent RNA polymerase as targets for drug and vaccine development: A review显示文摘The present pandemic has posed a crisis to the economy of the world and the health sector.Therefore,the race to expand research to understand some good molecular targets for vaccine and therapeutic development for SARS-CoV-2 is inevitable.The newly discovered coronavirus 2019(COVID-19)is a positive sense,single-stranded RNA,and enveloped virus,assigned to the beta CoV genus.The virus(SARS-CoV-2)is more infectious than the previously detected coronaviruses(MERS and SARS).Findings from many studies have revealed that S protein and RdRp are good targets for drug repositioning,novel therapeutic development(antibodies and small molecule drugs),and vaccine discovery.Therapeutics such as chloroquine,convalescent plasma,monoclonal antibodies,spike binding peptides,and small molecules could alter the ability of S protein to bind to the ACE-2 receptor,and drugs such as remdesivir(targeting SARS-CoV-2 RdRp),favipir,and emetine could prevent SASR-CoV-2 RNA synthesis.The novel vaccines such as mRNA1273(Moderna),3LNP-mRNAs(Pfizer/BioNTech),and ChAdOx1-S(University of Oxford/Astra Zeneca)targeting S protein have proven to be effective in combating the present pandemic.Further exploration of the potential of S protein and RdRp is crucial in fighting the present pandemic.Yusuf Muhammed Abduljalal Yusuf Nadabo Mkpouto Pius Bashiru Sani Jafar Usman Nasir Anka Garba Jaafaru Mohammed Sani Basit Opeyemi Olayanju Sunday Zeal Bala Musa Garba Abdullahi Misbahu Sambo 2021Biosafety and Health2021,3,5:1
