        Differential antioxidative and biochemical responses to aluminium stress in Brassica juncea cultivars

        Javed,Ahmad,Mohd,Affan,Baig,Arlene,Asthana,Ali,Asma,Abdulkareem,Al‑Huqail,Mohamed,Mohamed,Ibrahim,Mohammad,I,rfan,Q,ureshi 한국원예학회 2018 Horticulture, Environment, and Biotechnology Vol.59 No.5

        Aluminium (Al) toxicity in acidic soils limits crop production worldwide. We evaluated eleven genotypes of Brassica juncea (Mustard) under Al stress on basis of their growth and shortlisted two best among them for further comparative analysis. Our objective was to elucidate individual and differential oxidative damage and defence response elicited by Al treatment in selected mustard genotypes, ‘Pusa Tarak' and ‘Pusa Vijay'. Thirty-day-old plants of both genotypes were subjected to Al stress for a period of 24 h and 72 h. Concentration of superoxides was visible much higher in leaves of ‘Pusa Vijay' both at 24 h and 72 h, also confirmed by oxidative stress marker thiobarbituric acid reactive substances (TBARS). The activities of the enzymatic antioxidants superoxide dismutase (SOD), ascorbate peroxidase (APX), glutathione reductase (GR), glutathione S-transferase (GST), and catalase (CAT) were significantly higher in ‘Pusa Tarak' compared to control and ‘Pusa Vijay' at both time stages. Levels of non-enzymatic antioxidants glutathiones and ascorbates were already higher in ‘Pusa Vijay'; however, Al treatment increased their levels in both genotypes with non-significant changes on inter-genotypes basis. More and significant decline by Al in chlorophylls was observed in ‘Pusa Vijay'. Interestingly, increase in proline content by Al was much prominent in ‘Pusa Tarak' compared to ‘Pusa Vijay'. The in vitro antioxidant capacity estimation of mustard genotypes, evaluated by measuring 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging and hydroxyl radical scavenging (HRSA) activities proved that extract of ‘Pusa Tarak' can detoxify more radicals than ‘Pusa Vijay'. We conclude that ‘Pusa Tarak' can upregulate cellular antioxidants and osmoregulation, and quench more radicals compared to ‘Pusa Vijay'. The results will contribute for selection of better Brassica genus to be grown in Al rich acidic soils, and help in designing strategies for crop breeding and cultivation.

        Genotype and Allelic Frequencies of a Newly Identified Mutation Causing Blindness in Jordanian Awassi Sheep Flocks

        Jawasreh,,K.I.Z.,Ababneh,,H.,Awawdeh,,F.T.,Al-Massad,,M.A.,Al-Majali,,A.M. Asian Australasian Association of Animal Productio 2012 Animal Bioscience Vol.25 No.1

        A total of 423 blood samples were collected (during 2009 and 2010) from all the ram holdings at three major Jordanian governmental Awassi breeding stations (Al-Khanasry, Al- Mushairfa and Al-Fjaje) and two private flocks. All blood samples were screened for the presence of mutations at the CNGA3 gene (responsible for day blindness in Awassi sheep) using RFLP-PCR. The day blindness mutation was detected in all studied flocks. The overall allele and genotype frequencies of all studied flocks of the day blindness mutation were 0.088 and 17.49%, respectively. The genotype and allele frequencies were higher in station flocks than the farmer flocks (0.121, 24.15 and 0.012, 2.32, respectively). Al-Mushairfa and Al-Khanasry stations have the highest genotype and allele frequencies for the day blindness mutation that were 27.77, 30.00% and 0.14, 0.171, respectively. The investigated farmer flocks have low percentages (0.03, 5.88% at Al-Shoubak and 0.005 and 1.05%, at Al-Karak, respectively for genotype and allele frequencies) compared with the breeding stations. Ram culling strategy was applied throughout the genotyping period in order to gradually eradicate this newly identified day blindness mutation from Jordanian Breeding station, since they annually distribute a high percentage of improved rams to farmer's flocks.

        Microbial Consortia in Oman Oil Fields: A Possible Use in Enhanced Oil Recovery

        ( Al Bahry Saif N ), ( Abdulkader E. Elsahfie ), ( Yahya M. Al Wahaibi ), ( Ali S. Al Bimani ), ( Sanket J. Joshi ), ( Ratiba A. Al Maaini ), ( Wafa J. Al Alawai ), ( Yuichi Sugai ), ( Mussalam Al Mandhari ) 한국미생물 · 생명공학회 2013 Journal of microbiology and biotechnology Vol.23 No.1

        Microbial enhanced oil recovery (MEOR) is one of the most economical and efficient methods for extending the life of production wells in a declining reservoir. Microbial consortia from Wafra oil wells and Suwaihat production water, Al-Wusta region, Oman were screened. Microbial consortia in brine samples were identified using denaturing gradient gel electrophoresis and 16S rRNA gene sequences. The detected microbial consortia of Wafra oil wells were completely different from microbial consortia of Suwaihat formation water. A total of 33 genera and 58 species were identified in Wafra oil wells and Suwaihat production water. All of the identified microbial genera were first reported in Oman, with Caminicella sporogenes for the first time reported from oil fields. Most of the identified microorganisms were found to be anaerobic, thermophilic, and halophilic, and produced biogases, biosolvants, and biosurfactants as by-products, which may be good candidates for MEOR.

        알-하피즈 아랍어 연어 사전에 관한 적절한 평가: 코퍼스를 기반으로 한 연구

        알리알할라와니 ( Ali Al Halawani ), 히샴카다와르디 ( Hesham Khadawardi ), 모하메드엘아스카리 ( Mohamed Elaskary ) 한국외국어대학교 중동연구소 2015 중동연구 Vol.33 No.3

        연어(collocation) 학습은 외국인 학생과 외국어 학습자에게 있어매우 중요하다. 원어민은 배우지 않아도 자연스럽고 능숙하게 연어를 구사할 수 있지만, 외국인 학습자가 원어민 수준으로 외국어 실력을 향상시키기 위해서는 연어를 학습해야만 한다. 서구 언어학자들과 사전편찬자들이 연어에 대해 관심을 갖기 시작한 것은1933 년부터이다. 최초의 영어 연어 사전(the BBI)이 1986 년에 출간된 반면 아랍어 연어 사전은 2004 년에 처음 발간되었다. 이 논문은 최초의 아랍어 연어 사전인 Al-Hafiz 사전에 대해 살펴보고자 한다. 연어 사전은 번역가, 작가 그리고 외국어 학습자에게 없어서는 안될 필수품이다. 연어 번역에 나타나는 오역의 원인 중 하나는 번역가가 연어에 대한 자세한 설명과 예문이없는 일반 이중언어 사전을 참고하기 때문이다. 이 논문은 언어학적 방법론과 학문적 비평을 기반으로 한 현대 기술의 도입으로 아랍어-영어와 영어-아랍어 범용사전뿐만 아니라 특수사전 분야에서도 선도적 역할을 담당하게 하기 위함을 목적으로 한다. 이 점과 관련하여, 이 논문에서는 Al-Hafiz 사전의 장점과 단점에 대해살펴볼 것이다. 본 연구의 목적은 Al-Hafiz 사전에서 발견되는 오류들을 지적하기 보다는 오류의 수정을 통해 아랍어 사전편찬자들이 이런점들을 활용하여 같은 실수를 반복하지 않게 하는 데 있다. 사전편찬자가 사전 편찬에 좀더 심혈을 기울여서, 일반독자들조차쉽게 발견할 수 있는 오류들을 범하지 않았더라면 Al-Hafiz 사전은더 잘 만들어졌을 것이다. 이에 본 논문은 연어 사전을 편찬하는 데있어 코포라(corpora)나 소프트웨어(software) 같은 현대기술의 활용을 제안한다. Collocation has become one of the most controversial linguistic terms of today. As evidence to this, linguists did not agree up till today as to its exact definition, types or patterns. This may explain, to some extent, the scarcity of collocational dictionaries and their late appearance regardless of the huge number of collocations that can be found in general (i.e. noncollocational) lexicons and dictionaries of nearly all languages. Added to this is the difficulty of compiling a collocational dictionary unless modern technological tools such as computers, huge corpora, and text analysis software are used. This is true as the first English collocational dictionary appeared in 1986, the BBI, while in Arabic, the first one to appear was Hafiz in 2004 which is the main focus of this paper. This is exactly the reason behind our interest in this dictionary as it is already the first of its kind in Arabic as is mentioned by its author on its front cover. Collocation dictionaries are indispensable tools for the translator, writer and learner of any foreign language. One of the reasons behind the errors translators make in rendering collocations from one language to another is that they consult general-purpose bilingual dictionaries that do not provide the translators with detailed explanation or examples of collocations. Hence, the significance of this paper as it represents an attempt towards introducing a modern-technology-based linguistic methodological and academic criticism for evaluating such a great effort aiming at elevating it to the best shape it can be and to help it become a model to be emulated in the field of compiling specialized as well as non-specialized Arabic/ English and English/Arabic dictionaries.As the dictionary's author has committed-according to Al-Halawani-a number of methodological, editorial and translational mistakes; a matter which makes it incumbent upon specialists to look into its content to clarify such mistakes and attempt to amend them whenever possible.

      • Physical Activity and Cancer Prevention: Awareness and Meeting the Recommendations among Adult Saudis

        Amin,,Tarek,Tawfik,Al-Hammam,,Abudllah,Mohammed,AlMulhim,,Nasser,Abdullah,Al-Hayan,,Mohammed,Ibrahim,Al-Mulhim,,Mona,Mohammed,Al-Mosabeh,,Modhahir,Jawad,Al-Subaie,,Mohammed,Ali,Al-Hmmad,,Qassem,Ahmed Asian Pacific Organization for Cancer Prevention 2014 Asian Pacific journal of cancer prevention Vol.15 No.6

        Background: There is a scarcity of information about the proportion of the adult Saudi population that meet the recommended guidelines of physical activity (PA) to reduce cancer risk. Moreover, their awareness about the role of PA in cancer prevention is unclear. Objectives: This cross-sectional study aimed at estimating the proportion of adult Saudis meeting the PA guidelines, specifically those recommended by American Cancer Society (ACS) for cancer prevention, and to assess the public awareness about the role of PA in cancer prevention. Materials and Methods: Using a multistage sampling method, 2,127 adult Saudis of both genders were recruited from 6 urban and 4 rural primary health care centers in Al Hassa, Saudi Arabia. Participants were personally interviewed to gather information about their sociodemographic characteristics, searching activity about PA and cancer, and the time spent in leisure time PA (moderate and vigorous)/week using the Global Physical Activity Questionnaire with show cards. Finally, items about the role of PA in cancer risk reduction were inquired. Results: Of the included participants, 11.6% met the recommendations for cancer prevention (${\geq}45$ minutes of moderate-vigorous PA activity/${\geq}5$ days/week or 225 minutes/week). Multivariate regression showed that being male (AOR=1.49, CI=1.09-2.06), <20 years of age (AOR=3.11, CI=2.03-4.76), and unemployed (AOR=2.22, CI=1.57-3.18) were significant predictors for meeting PA recommendations for cancer prevention. Only 11.4% of the sample indicated correctly the frequency and duration of PA required for an average adult to be physically active and while >70% of them indicated the role of PA in prevention of hypertension, coronary heart disease and lowering elevated blood cholesterol, only 18.6% and 21.7% correctly mentioned the role of PA in reducing colon and breast cancer risk, respectively. Poor knowledge was found among those with less than college education and aged ${\geq}50$ years. The level of knowledge was significantly positively correlated with total leisure time PA of the participants. Conclusions: A minority of adult Saudis in Al Hassa was aware about the role of PA in cancer prevention and engaged in sufficient LTPA for cancer risk reduction benefits, highlighting the need for public health actions to include policies and programs that address factors deterring their participation in LTPA and increasing their awareness with remedies to manage the prevalent misconceptions.

      • Knowledge about Cervical Cancer Early Warning Signs and Symptoms, Risk Factors and Vaccination among Students at a Medical School in Al-Ahsa, Kingdom of Saudi Arabia

        Al-Darwish,,Abdulaziz,Ahmed,Al-Naim,,Abdullah,Fouad,Al-Mulhim,,Khalid,Saleh,Al-Otaibi,,Nasser,Khaled,Morsi,,Mohammed,Saad,Aleem,,Ansari,Mukhtar Asian Pacific Organization for Cancer Prevention 2014 Asian Pacific journal of cancer prevention Vol.15 No.6

        Background: Cervical cancer is the second most common cancer among females and also the most preventable. In the literature there is abundant evidence that awareness regarding cervical cancer and its prevention is low in the developing countries. Medical students are the future health professionals and can play an important role in increasing awareness among the general population. To assess the knowledge regarding symptoms, risk factors and prevention of cervical carcinoma among medical students in th Kingdom of Saudi Arabia, the present study was planned. Materials and Methods: This cross-sectional study was conducted using a self-administered questionnaire with students at the College of Medicine, King Faisal University, Al-Ahsa, KSA, from December 2012 to May 2013. Results: The responses of 188 students (males 111, females 77) in their second, third, fourth, and fifth years were recorded and used in the data analysis. The majority of the students were not aware of the early warning signs, symptoms and risk factors. On average, only 43.7% males and 56% of females were aware about the early signs and symptoms whereas 51.4% males and 57.8% females had knowledge about the risk factors of cervical cancers. Some 55% males and 46.8% females were unable to select the correct answer regarding human papilloma virus (HPV) infection as the cause of cervical cancer. Majority of the students (67%) were not aware about the availability of vaccine against HPV. Conclusions: Lack of knowledge regarding early signs and symptoms, risk factors and prevention of cervical cancer was observed in the present study.

        Thymus vulgaris (Thyme) Inhibits Proliferation, Adhesion, Migration, and Invasion of Human Colorectal Cancer Cells

        Afnan,Al-Menhali,Aisha,Al-Rumaihi,Hana,Al-Mohammed,Hana,Al-Mazrooey,Maryam,Al-Shamlan,Meaad,AlJassim,Noof,Al-Korbi,Ali,Hussein,Eid 한국식품영양과학회 2015 Journal of medicinal food Vol.18 No.1

        Colorectal cancer (CRC) remains one of the most common malignancies and a leading cause of cancer-related deaths. Its prognosis remains poor for patients with several grades of this disease. This underscores the need for alternative modalities, such as herbal medicines, to treat this disease. A commonly used plant that appears to be of high medicinal value is Thymus vulgaris L. However, the effects of this plant on the malignant behavior of human CRC cells remains poorly investigated. This study was undertaken to determine the anticancer efficacy of T. vulgaris extract (TVE) in CRC cells. Our results show that TVE inhibits proliferation in a concentration- and time-dependent fashion. This decreased proliferation was concomitant with increased apoptotic cell death as evidenced by increased caspase3/7 activity.Moreover, TVE also decreased adhesion to fibronectin in a concentration-dependent manner. The migratory and invasive capacities of HCT116 cells were significantly inhibited by TVE. Taken together, these data suggest that the TVE inhibits malignant phenotype of colon cancer cells. Therefore, T. vulgaris could have an anticancer effect and that some of its bioactive compounds may prove to be effective treatment modalities for human CRC.

        Adsorption desalination of chloride ions on composite natural–synthetic materials: An approach for the reduction of chlorine corrosion in electrodeionization units

        Aiman,E.,Al-Rawajfeh,Ehab,M.,Al-Shamaileh,Khaldoon,Al-Whoosh,Alaa,Al-Maabrah,Ramzi,Al-Zorqan,Rana,Zanoon,Khalid,Rawajfeh,Saleh,Al-Jufout 한국공업화학회 2013 Journal of Industrial and Engineering Chemistry Vol.19 No.6

        The release of chlorine in the electrodeionization (EDI) unit causes corrosion in the EDI unit, damaging ion exchange membranes and creating a safety risk for the workers. In this work, adsorption desalination of Cl ions on low-cost composite synthetic–natural Jordanian materials were investigated as an approach to prevent the release of corrosive chlorine gas at the positive electrode. The percentage removal reaches 25% at 25 min shaking time to 55% at 120 min, in a single batch experiment. The values of DH0, DS0, and DG0 indicate the favorability of physisorption. Zeolite and Pozzolana represent potential adsorbents of chloride.

        A Systematic Review and Meta-analysis of Randomized Controlled Trials Comparing Surgical versus Conservative Treatments for Acute Undisplaced or Minimally-Displaced Scaphoid Fractures

        Turki,A.,Al-Ajmi,Khalid,H.,Al-Faryan,Naif,F.,Al-Kanaan,Abdulmalik,A.,Al-Khodair,Thamer,H.,Al-Faryan,Maher,I.,Al-Oraini,Abdulelah,F,Bassas 대한정형외과학회 2018 Clinics in Orthopedic Surgery Vol.10 No.1

        Background: Surgical and conservative methods have been reported by various studies for high rates of fracture union and subsequent regain of function among patients with undisplaced or minimally-displaced scaphoid fractures. Hence, this study aims to analyze the best available evidence to comprehend the relative benefits and risks of these therapeutic options. Methods: A systematic search of the literature from different databases and search engines was performed with strict eligibility criteria to obtain the highest quality of evidence. All randomized controlled trials delineating the outcomes of surgical versus conservative treatments for acute undisplaced or minimally-displaced scaphoid fractures were included and then evaluated using scoring tools: Cochrane risk of bias tool and PEDro scale. Data were pooled using random-effects models with standard mean differences for continuous outcomes and risk ratios for dichotomous variables. Results: The search yielded 339 potentially related articles, further trimmed down to eight studies based on the eligibility criteria. The meta-analysis revealed that surgical treatment resulted in significantly better functional outcomes than conservative treatment. Furthermore, surgery resulted in the prevention of delayed union of fractures and reduction of time needed to return to work. Conclusions: While four studies reported advantages of surgical treatment, evidence was insufficient to provide a definitive conclusion that surgery is a better option. Due to the significant limitations with respect to certain variables, the superiority of one method to the other could not be established.
