Identification of autoanti-B antibody produced by B blood group, a case report

open access: yesZhongguo shuxue zazhi, 2022
目的 对1例罕见的B抗原特异性自身抗体标本进行鉴定分析。方法 采用经典试管法、吸收放散法、微柱凝胶法检测血型抗原及抗体。巯基试剂处理血浆、直接抗球蛋白分型鉴定抗体性质。序列特异引物引导的聚合酶链反应进行ABO基因分型,测序分析ABO基因1~7外显子核苷酸序列。结果 ABO血型正反定型不符,正定型B抗原4+,血浆与反定型B细胞凝集2+s,不规则抗体筛查阴性。吸收放散试验证实:存在特异性抗-B,抗体性质为IgM,4℃条件体外溶血试验阳性。SSP基因分型为B/O1;1 ...

Addressing Demographic Challenges Through Public–Private Partnerships: In Vitro Fertilization in Latvia

open access: yesWorld Medical &Health Policy, EarlyView.
ABSTRACT The study by Morshed‐Behbahani et al. highlights that financial barriers are not the sole obstacle to accessing infertility treatment. To ensure equal access for all, infertility treatment should be regarded as a universal human right, with the public sector assuming responsibility for its provision.

Global drivers of the conservation–invasion paradox

open access: yesConservation Biology, EarlyView.
Abstract The conservation–invasion paradox (CIP) refers to a long‐term phenomenon wherein species threatened in their native range can sustain viable populations when introduced to other regions. Understanding the drivers of CIP is helpful for conserving threatened species and managing invasive species, which is unfortunately still lacking. We compiled

Preparation and evaluation of mitomycin C-phospholipid complex-based novel targeted nanoscaled drug delivery systems [PDF]

open access: yes, 2015
丝裂霉素C是一种临床常用的广谱抗生素类抗癌药物。然而丝裂霉素C在静脉注射给药中受到诸多限制,如生物利用度极低、体内半衰期极短、非特异性全身分布、严重毒副作用等,使其最终到达肿瘤部位的血药浓度仅为静脉给药浓度的1/20左右。因此,如何最大限度地提高药物疗效以杀伤肿瘤细胞同时把药物毒副作用降低到最低程度无疑是丝裂霉素C在癌症化学治疗中的重要问题。本研究立足于自组装技术,我们设计并开发了基于丝裂霉素C-磷脂复合物的单药纳米传递系统以及基于丝裂霉素C(主药)-磷脂复合物和甲氨蝶呤前药(副药)的双药纳米传递系统 ...

Incorporating cyclone risk in the design of marine protected and conserved areas as an ecosystem‐based adaptation approach

open access: yesConservation Biology, EarlyView.
Abstract Marine protected and conserved areas (MPCAs) are promoted as an ecosystem‐based adaptation (EbA) approach to increase community and ecosystem resilience to climate change. However, traditional approaches to MPCA design typically do not consider climate risk or habitat condition under a climate threat.

Aureobasidium spp. ニヨル プルラン セイサン ジョウケン ノ ケントウ [PDF]

open access: yes, 1998
【緒言】一般に黒酵母と呼ばれているAureobasidium属は,菌体外多糖を生産するということで広く知られている.特にA.pullulansの生産するプルランは工業的に利用され,その収量を高めるための生産条件が検討され,栄養素では窒素源及び炭素源の影響及び菌株や栄養条件以外の培養条件の影響が報告されている.一方,プルラン生産と細胞形態との関連性については様々な見解があり,さらに形態変化に伴う細胞壁多糖構造の変化も明確にされていない.本研究では,本研究室で分離したAureobasidium spp ...

Assessing the Corn Belt as an anthropogenic barrier to migrating landbirds in the United States

open access: yesConservation Biology, EarlyView.
Abstract Migrating landbirds adjust their flight and stopover behaviors to efficiently cross inhospitable geographies, such as the Gulf of Mexico and the Sahara Desert. In addition to these natural barriers, birds may increasingly encounter anthropogenic barriers created by large‐scale changes in land use. One such barrier could be the Corn Belt in the

体外循环管理中的意外和处理

open access: yesZhongshan Daxue xuebao. Yixue kexue ban, 1982
体外循环是心内直视手术成功的重要因素之一,而人工心肺机的性能和体外循环的管理技术更是决定治疗效果的两个重要因素。随着心脏外科的发展,复杂的心内手术会使操作时间延长,如何才能做到体外循环安全可靠则仍然是一个重要的问题。我院近年来在体外循环手术的人工心肺机管理工作中,虽然积累了一些经验,但也有不少教训。在456例体外循环心内直视手术中,曾因电源中断、人工心机变压器烧毁、氧合器漏血或因氧合器组件粘合不密闭漏氧而产生大气泡,动脉泵管或过滤网袋破裂及机血凝固等27例意外(占5.9%,见表1 ...

On the normative roles of biodiversity and naturalness in conservation

open access: yesConservation Biology, EarlyView.
Abstract Nature is an opaque concept. Consequently, the term biodiversity conservation has replaced nature conservation in most conservation contexts. We review the conceptual indeterminacies that plague the terms nature and natural but then show that comparable difficulties plague biodiversity.
