Can radiomics improve the prediction of metastatic relapse of myxoid/round cell liposarcomas?

European Radiology - The strongest adverse prognostic factor in myxoid/round cell liposarcomas (MRC-LPS) is the presence of a round cell component above 5% within the tumor bulk. Its identification...     

Treatment of classical Hodgkin’s lymphoma in children and adolescents

Introduction: The treatment of classical Hodgkin lymphoma (cHL) in children is a story of success. Nowadays, more than 90% of patients are cured and overall survival is nearly 100% at 5 years. Efforts have been made to avoid related effects of therapies; therefore, children are treated using different chemotherapy schemes in comparison with adults.

Areas covered: This review includes a view of the clinical classification and risk assessment in children suffering from HL. The chemotherapy more commonly employed is revisited. The use of PET/CT to evaluate the disease in order to guide therapy is analyzed. New options of chemotherapy and emerging immunotherapy are also included.

Expert opinion: In order to make the right treatment choice, a proper initial assessment of risk is mandatory. The choice of therapy in these kinds of patients must be done according to the experience of the team, and also, the cost and logistics related to the eligible scheme are very important. If possible, efforts must be made to include PET/CT in guiding therapy and avoiding overtreatment and long-term adverse effects in children. New options in immunotherapy are emerging and must be considered with caution in selected patients.     

大花胡麻草环烯醚萜合酶基因的克隆与表达分析

目的克隆大花胡麻草环烯醚萜合酶基因(CgIS),并进行表达分析。方法以大花胡麻草根、茎、叶转录组中唯一的CgIS基因序列为基础,采用RT-PCR技术从大花胡麻草幼叶克隆CgIS基因,并进行组织特异性表达分析。结果大花胡麻草CgIS基因(GenBank登录号MH794270)全长1 185 bp,编码394个氨基酸;CgIS蛋白相对相对分子质量44 670,理论pI为6.17;该蛋白属于孕酮5β-还原酶(P5β-R)家族成员,可能定位于细胞质;该蛋白无信号肽,为亲水稳定蛋白,主要由α-螺旋(40.61%)和无规则卷曲(46.70%)构成;该蛋白具有SDR(短链脱氢酶/还原酶)和P5βR蛋白保守结构域;CgIS蛋白与芝麻SiIS蛋白亲缘关系最近;CgIS基因主要在叶中表达。结论克隆了CgIS基因,并对其进行表达分析,为进一步研究该基因的功能和环烯醚萜类的生物合成途径奠定基础。     

Completeness and timeliness of diphtheria-tetanus-pertussis,measles-mumps-rubella,and polio vaccines in young children with chronic health conditions: A systematic review

Objective

To systematically review literature on uptake and timeliness of diphtheria-tetanus-pertussis, measles-mumps-rubella, and/or polio-containing vaccines in infants who were born preterm, with a low birth weight, and/or with chronic health conditions that were diagnosed within the first 6?months of life.
