1Stereotactic body radiation therapy for non-small cell lung cancer:A review显示文摘Stereotactic body radiation therapy(SBRT) is the treatment of choice for medically inoperable patients with early stage non-small cell lung cancer(NSCLC). A literature search primarily based on PubMed electronic databases was completed in July 2018. Inclusion and exclusion criteria were determined prior to the search, and only prospective clinical trials were included. Nineteen trials from 2005 to 2018 met the inclusion criteria, reporting the outcomes of 1434 patients with central and peripheral early stage NSCLC. Patient eligibility,prescription dose and delivery, and follow up duration varied widely. Threeyears overall survival ranged from 43% to 95% with loco-regional control of up to 98% at 3 years. Up to 33% of patients failed distantly after SBRT at 3 years. SBRT was generally well tolerated with 10%-30% grade 3-4 toxicities and a few treatment-related deaths. No differences in outcomes were observed between conventionally fractionated radiation therapy and SBRT, central and peripheral lung tumors, or inoperable and operable patients. SBRT remains a reasonable treatment option for medically inoperable and select operable patients with early stage NSCLC. SBRT has shown excellent local and regional control with toxicity rates equivalent to surgery. Decreasing fractionation schedules have been consistently shown to be both safe and effective. Distant failure is common, and chemotherapy may be considered for select patients. However, the survival benefit of additional interventions, such as chemotherapy, for early stage NSCLC treated with SBRT remains unclear.Kavitha M Prezzano Sung Jun Ma Gregory M Hermann Charlotte I Rivers Jorge A Gomez-Suescun Anurag K Singh 2019World Journal of Clinical Oncology2019,10,1:10
2Arabidopsis PTD Is Required for Type Ⅰ Crossover Formation and Affects Recombination Frequency in Two Different Chromosomal Regions显示文摘In eukaryotes,crossovers together with sister chromatid cohesion maintain physical association between homologous chromosomes,ensuring accurate chromosome segregation during meiosis I and resulting in exchange of genetic information between homologues.The Arabidopsis PTD(Parting Dancers)gene affects the level of meiotic crossover formation,but its functional relationships with other core meiotic genes,such as AtSPO11-1,AtRAD51,and AtMSH4,are unclear;whether PTD has other functions in meiosis is also unknown.To further analyze PTD function and to test for epistatic relationships,we compared the meiotic chromosome behaviors of Atspol 1-1 ptd and AtradSl ptd double mutants with the relevant single mutants.The results suggest that PTD functions downstream of AtSPOll-1 and AtRAD51 in the meiotic recombination pathway.Furthermore,we found that meiotic defects in rck ptd and Atmsh4 ptd double mutants showed similar meiotic phenotypes to those of the relevant single mutants,providing genetic evidences for roles of PTD and RCK in the type I crossovers pathway.Moreover,we employed a pollen tetrad-based fluorescence method and found that the meiotic crossover frequencies in two genetic intervals were significantly reduced from 6.63%and 22.26%in wild-type to 1.14%and 6.36%,respectively,in the ptd-2 mutant.These results revealed new aspects of PTD function in meiotic crossover formation.Pingli Lu Asela J.Wijeratne Zhengjia Wang Gregory P.Copenhaver Hong Ma 2014Journal of Genetics and Genomics2014,41,3:5

15Investigating the Effects of Para-methoxy Substitution in Sterically Enhanced Unsymmetrical Bis(arylimino)pyridine-cobalt Ethylene Polymerization Catalysts显示文摘A group of five bis(arylimino)pyridine-cobalt(Ⅱ)chloride complexes,[2-{(2,6-(Ph_(2)CH)_(2)-4-MeOC_(6)H_(2))N=CMe}-6-(ArN=CMe)C_5 H_(3)N]CoCl_(2)(Ar=2,6-Me_(2)C_(6)H_(3)Co1,2,6-Et_(2)C_(6)H_(3)Co2,2,6-iPr_(2)C_(6)H_(3)Co3,2,4,6-Me_(3)C_(6)H_(2)Co4,2,6-Et_(2)-4-MeC_(6)H_(2)Co5),each containing one N-4-methoxy-2,6-dibenzhydrylphenyl group and one smaller sterically/electronically variable N-aryl group,have been synthesized in good yield(>71%)from the corresponding neutral terdentate nitrogen-donor precursor,L1-L5.All complexes have been characterized by^(1)H-NMR and FTIR spectroscopy with the former highlighting the paramagnetic nature of these cobaltous species and the unsymmetrical nature of the chelating ligand.The molecular structures of Co3 and Co4 emphasize the steric differences of the two inequivalent N-aryl groups and the distorted square pyramidal geometry about the metal centers.In the presence of MAO or MMAO,Co1-Co5 collectively displayed high activities for ethylene polymerization producing high molecular weight polyethylenes that,in general,exhibited narrow dispersities(M_w/M_n values:2.12-4.07).Notably,the least sterically hindered Co1 when activated with MAO was the most productive(6.92×10^(6)g_(PE)·mol^(-1)_((Co))·h^(-1))at an operating temperature of60℃.Conversely,the most sterically hindered Co3/MMAO produced the highest molecular weight polyethylene(M_w=6.29×10^(5)g·mol^(-1)).All the polymers displayed high linearity as demonstrated by their melting temperatures(>130℃)and their~1 H-and^(13)C-NMR spectra.By comparison of Co1 with its para-methyl,-chloro and-nitro counterparts,the presence of the para-methoxy substituent showed the most noticeable effect of enhancing the thermal stability of the catalyst.Yi Yan Shi-Fang Yuan Ming Liu Gregory A.Solan Yan-Ping Ma Tong-Ling Liang Wen-Hua Sun 2022Chinese Journal of Polymer Science2022,40,3:1
