1Performance assessment and microbial diversity of two pilot scale multi-stage sub-surface flow constructed wetland systems显示文摘This study assessed the performance and diversity of microbial communities in multi-stage sub-surface flow constructed wetland systems(CWs). Our aim was to assess the impact of configuration on treatment performance and microbial diversity in the systems. Results indicate that at loading rates up to 100 g BOD5/(m2·day), similar treatment performances can be achieved using either a 3 or 4 stage configuration. In the case of phosphorus(P), the impact of configuration was less obvious and a minimum of 80% P removal can be expected for loadings up to 10 g P/(m2·day) based on the performance results obtained within the first16 months of operation. Microbial analysis showed an increased bacterial diversity in stage four compared to the first stage. These results indicate that the design and configuration of multi-stage constructed wetland systems may have an impact on the treatment performance and the composition of the microbial community in the systems, and such knowledge can be used to improve their design and performance.A.O.Babatunde Raul Miranda-Caso Luengo Mehreen Imtiaz Y.Q.Zhao Wim G.Meijer 2016Journal of Environmental Sciences2016,28,8:1

5Considerations for gluten free foods-pearl and finger millet processing and market demand显示文摘The market demand for gluten free foods is increasing due to frequent incidences of celiac disease and increasing awareness on consumption of gluten free foods.Millets have become the major constituent of diet as they are gluten-free and also excellent sources of micro and macro nutrients such as vitamins,minerals,dietary fibers and phenolic compounds.Among various millets,the finger millet and the pearl millet are the two most important and common millet varieties grown extensively.Since,they are regarded as the staple foods of the poor and vulnerable populations,development of new products and improvements in their nutritional quality will aid in the general health of these population.Processing of millets and production of variable gluten-free ready-to-eat and nutritional supplements has increased their market value in the recent years.Furthermore,processing can also help in shelf-life extension of the millets with nutritional enrichment,expanding its markets to non-traditional millet consumers.In this context,the present review is aimed to focus on the current processing methods to develop products from the two millet varieties that are gluten free and outline their nutritional benefits.Manivannan Selladurai Manoj Kumar Pulivarthi Anu Suprabha Raj Mehreen Iftikhar P.V.Vara Prasad Kaliramesh Siliveru 2023Grain & Oil Science and Technology2023,6,2:0

7Modifications of the Optimal Auxiliary Function Method to Fractional Order Fornberg-Whitham Equations显示文摘In this paper,we present a new modification of the newly developed semi-analytical method named the Optimal Auxilary Function Method(OAFM)for fractional-order equations using the Caputo operator,which is named FOAFM.The mathematical theory of FOAFM is presented and the effectiveness of this method is proven by using it with well-known Fornberg-Whitham Equations(FWE).The FOAFM results are compared with other method results along with their exact solutions with the help of tables and plots to prove the validity of FOAFM.A rapidly convergent series solution is obtained from FOAFMand is validated by comparison with other results.The analysis proves that ourmethod is simply applicable,contains less computationalwork,and is rapidly convergent to the exact solution at the first iteration.A series solution to the problem is obtained with the help of FOAFM.The validity of FOAFM results is validated by comparing its results with the results available in the literature.It is observed that FOAFM is simply applicable,contains less computational work,and is fastly convergent.The convergence and stability are obtained with the help of optimal constants.FOAFM is very easy in applicability and provides excellent results at the first iteration for complex nonlinear initial/boundary value problems.FOAFM contains the optimal auxiliary constants through which we can control the convergence as FOAFM contains the auxiliary functions D_(1),D_(2),D_(3)...in which the optimal constants G_(1),G_(2),...and the control convergence parameters exist to play an important role in getting the convergent solution which is obtained rigorously.The computational work in FOAFM is less when compared to other methods and even a low-specification computer can do the computational work easily.Hakeem Ullah Mehreen Fiza Ilyas Khan Abd Allah A.Mosa Saeed Islam Abdullah Mohammed 2023Computer Modeling in Engineering & Sciences2023,,7:0
8Screening outcomes of household contacts of multidrug-resistant tuberculosis patients in Peshawar,Pakistan显示文摘Objective:To assess the profile of TB/multidrug-resistant TB(MDR-TB) among household contacts of MDR-TB patients.Methods:Close contacts of MDR-TB patients were traced in the cross-sectional study.Different clinical,radiological and bacteriological were performed to rule out the evidence of TB/MDR-TB.Results:Between January 2012 and December 2012,a total of 200 index MDR-TB patients were initiated on MDR-TB treatment,out of which home visit and contacts screening were conducted for 154 index cases.Of 610 contacts who could be studied,41(17.4%) were diagnosed with MDR-TB and 10(4.2%) had TB.The most common symptoms observed were cough,chest pain and fever.Conclusions:The high incidence of MDR-TB among close contacts emphasize the need for effective contact screening programme of index MDR-TB cases in order to cut the chain of transmission of this disease.Arshad Javaid Mazhar Ali Khan Mir Azam Khan Sumaira Mehreen Anila Basit Raza Ali Khan Muhammad Ihtesham Irfan Ullah Afsar Khan Ubaid Ullah 2016Asian Pacific Journal of Tropical Medicine2016,9,9:0
9Tamoxifen does not d eteriorate cardiac function in female alphaMHC-MerCreMer transgenic mice显示文摘Cre-loxP recombination system is widely used in gene function research to realize specific gene knockout or knockin through DNA editing.TheαMHC-MerCreMer transgenic mouse line can achieve conditional cardiomyocyte-specific gene editing and make itself be of high value in cardiovascular research.However,there is an ongoing controversy on cardiomyopathy caused by unspecific Cre activity or related to tamoxifen overload,and the majority of studies only focused on male mice.Here,we investigated in femaleαMHC-MerCreMer mice the effect of tamoxifen on myocardia at a conventional dose of 20 mg/kg for five consecutive days by intraperitoneal injection.Our results confirmed that the conventional dose of tamoxifen administration effectively knock down myocardial MED1 expression within one week,without any changes in body weight or heart and liver mass after a 2-week washout period.Serological examination showed that tamoxifen did not deteriorate hepatic or renal function.Hematoxylin-eosin and Sirius red staining revealed no difference in the structure or fibrosis deposition in the heart upon tamoxifen treatment.F4/80 immunohistochemistry staining showed no signs of increased macrophage infiltration in myocardia.The results of RT-qPCR also confirmed the histological observations.Furthermore,differences in energy metabolism and inflammatory response were observed in femaleαMHC-MerCreMer mice,and the underlying mechanism still needs to be clarified.Tuo Han Jie Gao Mehreen Fatima Yi-Wen Wang Li-Xia Wang Cong-Xia Wang 2021Life Research2021,4,4:0
10Multi-strain Inoculation with PGPR Producing ACC Deaminase is More Effective Than Single-strain Inoculation to Improve Wheat (Triticum aestivum) Growth and Yield显示文摘Rhizosphere bacteria that colonize plant roots and confer beneficial effects are referred as plant growth promoting rhizobacteria(PGPR).Among all PGPR,some rhizobacteria have an ability to produce ACC deaminase enzyme.This enzyme catalyzes stress ACC into a-ketobutyrate and ammonia instead of letting it to be converted to ethylene.Ethylene level rises in plants under stress conditions i.e.,drought,salinity,poor soil fertility etc.As poor soil fertility is a big hurdle to achieve the optimum yield of crops,inoculation of ACC deaminase PGPR can overcome this problem to some extent.The aim of the current study was to examine the influence of multi-strain and single-strain inoculation of different ACC deaminase producing PGPR on wheat growth and yield.There were three PGPR strains,Enterobacter cloacae,Serratia ficaria and Burkholderia phytofirmans which were used as consortia and single-strain inoculations.The results showed that inoculation of E.cloacae+S.ficaria+B.phytofirmans significantly increased plant height(63%),spike length(61%),number of spikelets spike-1(61%),number of grains spike-1(131%),1000 grains weight(33%),grains yield(71%),straw yield(71%)and biological yield(68%)of wheat as compared to control.A significant improvement in N(37 and 200%),P(46 and 166%)and K(39 and 61%)of seeds and shoot respectively,validated the efficacious and more effective role of multi-strain(E.cloacae+S.ficaria+B.phytofirmans)inoculation over control.It is obviously concluded that multi-strain ACC deaminase producing PGPR inoculation is a better approach as compared to single-strain inoculation for the improvement in growth and yield of wheat.Muhammad Zafar-ul-Hye Misbah Batool Zahra Subhan Danish Mazhar Abbas Abdur Rehim Muhammad Naeem Akbar Ayesha Iftikhar Mehreen Gul Ifat Nazir Maria Abid Muhammad Tahzeeb-ul-Hassan Maria Murtaza 2020Phyton-International Journal of Experimental Botany2020,89,2:0
11Synthesis,Urease Inhibition and Molecular Modelling Studies of Novel Derivatives of the Naturally Occurring b-Amyrenone显示文摘Urease enzyme(UE)has been reported to be a potent virulence factor for Helicobacter pylori(HP)bacteria indicated to be responsible for various gastrointestinal diseases.Therefore,the spread of HP,currently regarded by the World Health Organization as a class 1 carcinogen,could be better controlled by targeting UE.It is in this line that we have synthesized three new derivatives(2–4)of the naturally occurring olean-12-en-3-one(1),which was previously isolated from the figs of Ficus vallis-choudae Delile(Moraceae).Among the synthesized compounds,3 and 4 contain an indole moiety.Their structures were unambiguously assigned by spectroscopic and spectrometric techniques(1D-NMR,2D-NMR and MS).The starting material and the synthesized compounds were screened for UE inhibition activity,and showed significant activities with IC50 values ranging from 14.5 to 24.6 lM,with compound(1)being the most potent as compared to the positive control thiourea(IC50=21.6 lM).Amongst the synthetic derivatives,compound 4 was the most potent(IC50-=17.9 lM),while the others showed activities close to that of the control.In addition,molecular docking study of target compounds 2–4 was performed in an attempt to explore their binding mode for the design of more potent UE inhibitors.Jean J.K.Bankeu Hira Sattar Yannick S.F.Fongang Syeda W.Muhammadi Conrad V.Simoben Fidele Ntie-Kang Guy R.T.Feuya Marthe A.T.Tchuenmogne Mehreen Lateef Bruno N.Lenta Muhammad S.Ali Augustin S.Ngouela 2019Natural Products and Bioprospecting2019,9,1:0
