| 3 | Antimicrobial activity of mangrove plant(Lumnitzera littorea)显示文摘Objective:To investigate the antimicrobial activities of n-hexane.ethyl acetate and methanol extracts of the leaves of Lumnitzera littorea(L littorea) against six human pathogenic microbes. Methods:The antimicrobial activity was evaluated using disc diffusion and microdilution methods.Results:The antimicrobial activities of the crude extracts were increased with increasing the concentration.It is clear that n-hexane extract was the most effective extract. Additionally.Gram positive Bacillus cereus(B.cereus) appear to be the most sensitive strain while Pseudomonas aeruginosa(P.aeruginosa) and the yeast strains(Candida albicans(C. albicans) and Cryptococcus neoformans(C.neqformans)) appear to be resistance to the tested concentrations since no inhibition zone was observed.The inhibition of microbial growth at concentration as low as 0.04 mg/ml.indicated the potent antimicrobial activity of L littorea extracts.Conclusions:The obtained results are considered sufficient for further study to isolate the compounds responsible for the activity and suggesting the possibility of finding potent antibacterial agents from L littorea extracts. | Shahbudin Saad Muhammad Taher Deny Susanti Haitham Qaralleh Nurul Afifah Binti Abdul Rahim | 2011 | Asian Pacific Journal of Tropical Medicine2011,4,7: | 7 |
| 4 | Prosaposin ablation inactivates the MAPK and Akt signaling pathways and interferes with the development of the prostate gland显示文摘The recent development of a prosaposin-/-mouse model has allowed the investigation of the role of prosaposin in the development of the male reproductive organs.A morphometric analysis of the male reproductive system of 37 days old mice revealed that prosaposin ablation produced a 30% reduction in size and weight of the testes,37% of the epididymis,75% of the seminal vesicles and 60% of the prostate glands.Light microscopy(LM) showed that smaller testis size from homozygous mutant mice was associated with reduced spermiogenesis.Both,dorsal and ventral lobules of the prostate glands were underdeveloped in the homozygous mutant.LM analysis also showed that prostatic alveoli were considerably smaller and lined by shorter epithelial cells in the homozygous mutant.Smaller tubular diameter and shorter undifferentiated epithelial cells were also observed in seminal vesicles and epididymis. In the efferent ducts of the homozygous mutant mice,the epithelium was composed exclusively of ciliated cells in contrast to the heterozygotes,which showed the presence of nonciliated cells.Radioimmunoassays demonstratedthat testosterone levels were normal or higher in mice with the inactivated prosaposin gene.Immunostaining of prostate sections with an anti-androgen receptor antibody showed that the epithelial cells lining the alveoli express androgen receptor in both the heterozygous and homozygous tissue.Similarly,sections immunostained with antibodies to the phosphorylated MAPKs and Akts strongly reacted with tall prostatic secretory cells in prostate from heterozygous mouse.On the other hand,the epithelial cells in the homozygous prostate remained unstained or weakly stained.These findings demonstrate that inactivation of the prosaposin gene affected the development of the prostate gland and some components of the MAP pathway. | Carlos R.Morales Haitham Badran | 2003 | Asian Journal of Andrology2003,5,1: | 6 |

| 6 | Antimicrobial activity and essential oils of Curcuma aeruginosa,Curcuma mangga,and Zingiber cassumunar from Malaysia显示文摘Objective:To analyze the chemical composition of the essential oils of Curcuma aeruginosa (C.aeruginosa),Curcuma mangga(C.mangga),and Zingiber cassumunar(Z.cassumunar). and study their antimicrobial activity.Methods:Essential oils obtained by steam distillation were analyzed by gas chromatography-mass speclrometry(GC-MS).The antimicrobial activity of the essential oils was evaluated against four bacteria:Bacillus cereus(H.cereus).Staphylococcus aureus(S.aureus).Escherichia coli(E.coli).and Pseudomonas aeruginosa(P.aeruginosa);and two fungi:Candida albicans(C.albicans) and Cyptococcus neoformans(C.neoformans),using disc-diffusion and broth microdilution methods.Results:Cycloisolongifolene,8.9-dehydro-9- formyl(35.29%) and dihydrocoslunolide(22.51%) were the major compounds in C.aeruginosa oil; whereas caryophyllene oxide(18.71%) and caryophyllene(12.69%) were the major compounds in C.mangga oil:and 2,6.9,9-tetramethyl-2.6.10-cycloundecatrien-1-one(60.77%) andα-caryophyllene(23.92%) were abundant in Z.cassumunar oil.The essential oils displayed varying degrees of antimicrobial activity against all lested microorganisms.C.mangga oil had the highest and most broad-spectrum activity by inhibiting all microorganisms tested,with C.neoformans being the most sensitive microorganism by having the lowest minimum inhibitory concentration(MIC) and minimum fungicidal concentration(MFC) values of 0.1μL/mL. C.aeruginosa oil showed mild antimicrobial activity,whereas Z.cassumunar had very low or weak activity against the tested microorganisms.Conclusions:The preliminary results suggest promising antimicrobial properties of C.mangga and C.aeruginosa,which may be useful for food preservation,pharmaceutical treatment and natural therapies. | Tg Siti Amirah Tg Kamazeri Othman Abd Samah Muhammad Taher Deny Susanti Haitham Qaralleh | 2012 | Asian Pacific Journal of Tropical Medicine2012,5,3: | 5 |
| 7 | Viral respiratory infections among Hajj pilgrims in 2013显示文摘Middle East respiratory syndrome coronavirus(MERS-Co V) has emerged in the Arabian Gulf region, with its epicentre in Saudi Arabia, the host of the ‘Hajj' which is the world's the largest mass gathering. Transmission of MERS-Co V at such an event could lead to its rapid worldwide dissemination. Therefore, we studied the frequency of viruses causing influenza-like illnesses(ILI) among participants in a randomised controlled trial at the Hajj 2013. We recruited 1038 pilgrims from Saudi Arabia, Australia and Qatar during the first day of Hajj and followed them closely for four days. A nasal swab was collected from each pilgrim who developed ILI. Respiratory viruses were detected using multiplex RT-PCR. ILI occurred in 112/1038(11%) pilgrims. Their mean age was 35 years, 49(44%) were male and 35(31%) had received the influenza vaccine pre-Hajj. Forty two(38%) pilgrims had laboratory-confirmed viral infections; 28(25%) rhinovirus, 5(4%) influenza A, 2(2%) adenovirus, 2(2%) human coronavirus OC43/229 E, 2(2%) parainfluenza virus 3, 1(1%) parainfluenza virus 1, and 2(2%) dual infections. No MERS-Co V was detected in any sample. Rhinovirus was the commonest cause of ILI among Hajj pilgrims in 2013. Infection control and appropriate vaccination are necessary to prevent transmission of respiratory viruses at Hajj and other mass gatherings. | Osamah Barasheed Harunor Rashid Mohammad Alfelali Mohamed Tashani Mohammad Azeem Hamid Bokhary Nadeen Kalantan Jamil Samkari Leon Heron Jen Kok Janette Taylor Haitham El Bashir Ziad A.Memish Elizabeth Haworth Edward C.Holmes Dominic E Dwyer Atif Asghar Robert Booy | 2014 | Virologica Sinica2014,29,6: | 3 |
| 8 | A Secure Key Management Scheme for Heterogeneous Secure Vehicular Communication Systems显示文摘Intelligent transportation system(ITS)is proposed as the most effective way to improve road safety and traffic efficiency.However,the future of ITS for large scale transportation infrastructures deployment highly depends on the security level of vehicular communication systems(VCS).Security applications in VCS are fulfilled through secured group broadcast.Therefore,secure key management schemes are considered as a critical research topic for network security.In this paper,we propose a framework for providing secure key management within heterogeneous network:The security managers(SMs)play a key role in the framework by retrieving the vehicle departure information,encapsulating block to transport keys and then executing rekeying to vehicles within the same security domain.The first part of this framework is a novel Group Key Management(GKM)scheme basing on leaving probability(LP)of vehicles to depart current VCS region.Vehicle's LP factor is introduced into GKM scheme to achieve a more efficient rekeying scheme and less rekeying costs.The second component of the framework using the blockchain concept to simplify the distributed key management in heterogeneous VCS domains.Extensive simulations and analysis are provided to show the effectiveness and efficiency of the proposed framework:Our GKM results demonstrate that probability-based BR reduces rekeying cost compared to the benchmark scheme,while the blockchain decreases the time cost of key transmission over heterogeneous networks. | LEI Ao Chibueze Ogah Philip Asuquo Haitham Cruickshank SUN Zhili | 2016 | ZTE Communications2016,14,B06: | 3 |
| 9 | Hepatocellular injury and the mortality risk among patients with COVID-19: A retrospective cohort study显示文摘BACKGROUND Clearly,infection with severe acute respiratory syndrome coronavirus 2 is not limited to the lung but also affects other organs.We need predictive models to determine patients’prognoses and to improve health care resource allocation during the coronavirus disease 2019(COVID-19)pandemic.While treating COVID-19,we observed differential outcome prediction weights for markers of hepatocellular injury among hospitalized patients.AIM To investigate the association between hepatocellular injury and all-cause inhospital mortality among patients with COVID-19.METHODS This multicentre study employed a retrospective cohort design.All adult patients admitted to Al-Azhar University Hospital,Assiut,Egypt and Abo Teeg General Hospital,Assiut,Egypt with confirmed COVID-19 from June 1,2020,to July 30,2020 were eligible.We categorized our cohort into three groups of(1)patients with COVID-19 presenting normal aminotransferase levels;(2)patients with COVID-19 presenting one-fold higher aminotransferase levels;and(3)patients with COVID-19 presenting two-fold higher aminotransferase levels.We analysed the association between elevated aminotransferase levels and all-cause in-hospital mortality.The survival analysis was performed using the Kaplan–Meier method and tested by log-rank analysis.RESULTS In total,376 of 419 patients met the inclusion criteria,while 29(8%)patients in our cohort died during the hospital stay.The median age was 40 years(range:28-56 years),and 51%were males(n=194).At admission,54%of the study cohort had liver injury.The pattern of liver injury was hepatocellular injury with an aspartate aminotransferase(AST)predominance.Admission AST levels were independently associated with all-cause in-hospital mortality in the logistic regression analysis.A one-fold increase in serum AST levels among patients with COVID-19 led to an eleven-fold increase in in-hospital mortality(P<0.001).Admission AST levels correlated with C-reactive protein(r=0.2;P<0.003)and serum ferritin(r=0.2;P<0.0002)levels.Admission alanine aminotransferase levels correlated with serum ferritin levels(r=0.1;P<0.04).Serum total bilirubin levels were independently associated with in-hospital mortality in the binary logistic regression analysis after adjusting for age and sex but lost its statistical significance in the fully adjusted model.Serum ferritin levels were significantly associated with in-hospital mortality(P<0.01).The probability of survival was significantly different between the AST groups and showed the following order:a two-fold increase in AST levels>a one-fold increase in in AST levels>normal AST levels(P<0.0001).CONCLUSION Liver injury with an AST-dominant pattern predicts the severity of COVID-19.Elevated serum ferritin levels are associated with fatal outcomes. | Ali Madian Ahmed Eliwa Hytham Abdalla Haitham A Azeem Aly | 2021 | World Journal of Hepatology2021,13,8: | 3 |
| 10 | Irrigated pinto bean crop stress and yield assessment using ground based low altitude remote sensing technology显示文摘The pinto bean is one of widely consumed legume crop that constitutes over 42%of the U.S dry bean production.However,limited studies have been conducted in past to assess its quantitative and qualitative yield potentials.Emerging remote sensing technologies can help in such assessment.Therefore,this study evaluates the role of ground-based multispectral imagery derived vegetation indices(VIs)for irrigated the pinto bean stress and yield assessments.Studied were eight cultivars of the pinto bean grown under conventional and strip tillage treatments and irrigated at 52%and 100%of required evapotranspiration.Imagery data was acquired using a five-band multispectral imager at early,mid and late growth stages.Commonly used 25 broadband VIs were derived to capture crop stress traits and yield potential.Principal component analysis and Spearman’s rank correlation tests were conducted to identify key VIs and their correlation(rs)with abiotic stress at each growth stage.Transformed difference vegetation index,nonlinear vegetation index(NLI),modified NLI and infrared percentage vegetation index(IPVI)were consistent in accounting the stress response and crop yield at all growth stages(rs>0.60,coefficient of determination(R2):0.50–0.56,P<0.05).Ten other VIs significantly accounted for crop stress at early and late stages.Overall,identified key VIs may be helpful to growers for precise crop management decision making and breeders for crop stress response and yield assessments. | Rakesh Ranjan Abhilash KChandel Lav R.Khot Haitham YBahlol Jianfeng Zhou Rick ABoydston Phillip NMiklas | 2019 | Information Processing in Agriculture2019,6,4: | 3 |

| 14 | Fabrication of Electrospun Levodopa-Carbidopa Fixed-Dose Combinations显示文摘Introduction Parkinson’s disease(PD)is a disabling disorder that signifi-cantly affects a patient’s quality of life[1].Treatments are available,but only 10%of PD patients fully adhere to their treatment regimens[2].Non-adherence is a serious problem linked to worsening symptoms and increased motor fluc-tuations[3-5].Levodopa(LD)remains the most effective treatment for PD[6].However,a single dosing treatment is only effective in the early phase of the disease.In the severe phase,4-5 years after diagnosis,the therapeutic window of dopamine becomes narrow,and due to its short half-life of between 0.7 and 1.4 h dosing of LD will be required every 2 h[7-9].One way to ameliorate this issue is to co-admin-ister LD with carbidopa(CD),which can increase LD’s oral bioavailability to 40-70%[10]. | Haitham Bukhary Gareth R.Williams Mine Orlu | 2020 | Advanced Fiber Materials2020,2,4: | 2 |
