| 1 | Chemical composition of essential oils and in vitro antioxidant activity of fresh and dry leaves crude extracts of medicinal plant of Lactuca Sativa L.native to sultanate of Oman显示文摘Objective:To isolate and analyse the chemical composition in the essential oils and free radical scavenging activity of different crude extracts from the fresh and dry leaves of vegetable plants of Lactuca sativa L.(L.sativa).Methods:The essential oils and volatile chemical constituents were isolated from the fresh and dry leaves of L.sativa(lettuce)grown in Sultanate of Oman by hydro distillation method.The antioxidant activity of the crude extracts was carried out by well established free radical scavenging activity(DPPH)method.Results:About 20 chemical compounds of different concentration representing 83.07%and 79.88%respectively were isolated and identified by gas chromatography-mass spectroscopy in the essential oils isolated from the fresh and dry leaves asα-pinene(5.11%and 4.05%).γ-cymene(2.07%and 1.92%),thymol(11.55%and 10.73%),durenol(52.00%and 49.79%),α-terpinene(1.66%and 1.34%),thymol acetate(0.99%and 0.67%),caryophyllene(2.11%and 1.98%),spathulenol(3.09%and 2.98%).camphene(4.11%and3.65%),limonene(1.28%and 1.11%)representing these major chemical compounds.However,some other minor chemical constituents were also isolated and identified from the essential oil of lettuce including p-pinene,α-terpinolene,linalool,4-terpineol,α-terpineol,o-methylthymol,L-alloaromadendrene and viridiflorene.Conclusions:The chemical consliluents in the essential oils from the locally grown lettuce were identified in the following classes or groups of chemical compounds such as monoterpenes,sesquiterpenes volatile organic compounds and their oxygenated hydrocarbons.Therefore,the essential oils and the crude extracts from Omani vegetable species of lettuce are active candidates which would be used as antioxidant,antifungal or antimicrobial agents in new drugs preparation for therapy of infectious diseases. | Rahma Said Salim Al Nomaani Mohammad Amzad Hossain Afaf Mohammed Weli Qasim Al-Riyami Jamal Nasser Al-Sabahi | 2013 | Asian Pacific Journal of Tropical Biomedicine2013，3，5： | 3 |
| 2 | Current debate in the oncologic management of rectal cancer显示文摘Despite the considerable amount of research in the field,the management of locally advanced rectal cancer remains a subject to debate.To date,effective treatment centers on surgical resection with the standard approach of total mesorectal resection.Radiation therapy and chemotherapy have been incorporated in order to decrease local and systemic recurrence.While it is accepted that a multimodality treatment regimen is indicated,there remains significant debate for how best to accomplish this in regards to order,dosing,and choice of agents.Preoperative radiation is the standard of care,yet remains debated with the option for chemoradiation,short course radiation,and even ongoing studies looking at the possibility of leaving radiation out altogether.Chemotherapy was traditionally incorporated in the adjuvant setting,but recent reports suggest the possibility of improved efficacy and tolerance when given upfront.In this review,the major studies in the management of locally advanced rectal cancer will be discussed.In addition,future directions will be considered such as the role of immunotherapy and ongoing trials looking at timing of chemotherapy,inclusion of radiation,and nonoperative management. | Trish Millard Paul R Kunk Erika Ramsdale Osama E Rahma | 2016 | World Journal of Gastrointestinal Oncology2016，8，10： | 3 |
| 3 | B Cell-mediated Humoral Immunity in Chronic Hepatitis B Infection显示文摘B cell-mediated humoral immunity plays a vital role in viral infections,including chronic hepatitis B virus(HBV)infection,which remains a critical global public health issue.Despite hepatitis B surface antigen-specific antibodies are essential to eliminate viral infections,the reduced immune functional capacity of B cells was identified,which was also correlated with chronic hepatitis B(CHB)progression.In addition to B cells,T follicular helper(Tfh)cells,which assist B cells to produce antibodies,might also be involved in the process of anti-HBVspecific antibody production.Here,we provide a comprehensive review of the role of various subsets of B cells and Tfh cells during CHB progression and discuss current novel treatment strategies aimed at restoring humoral immunity.Understanding the mechanism of dysregulated B cells and Tfh cells will facilitate the ultimate functional cure of CHB patients. | Yang Li Shengxia Yin Rahma Issa Xin Tong Guiyang Wang Juan Xia Rui Huang Guangmei Chen Dan Weng Chen Chen Chao Wu Yuxin Chen | 2021 | Journal of Clinical and Translational Hepatology2021，9，4： | 2 |
