Analysis of risks and measures on the blade damage of offshore wind turbine during strong typhoons——enlightenment

Wang Jingquan,Chen Zhengqing

Strategic Study of CAE 2010, Volume 12, Issue 11,   Pages 32-34

Abstract:

In september 2003, the fan blades of wind turbine were damaged by typhoon "cuckoo"  in Shanwei Red Bay wind farm, an offshore hilly land. It can be concluded from the failure modes that the blades flutter have occurred and significantly reversed, which was related to the negative terrain. From this instance of the term, under the same intensity of typhoons, the risk of blade damage of sea wind turbine may be lower than that of coastal ones because of flat sea lack of local change conditions of wind direction. The storm also showed that it was the key for blade loss prevention to keep the wind turbine be paused state of stopping rotation, feathering and yawing.

New medical risks affecting obstetrics after implementation of the two-child policy in China

Qiang Li, Dongrui Deng

Frontiers of Medicine 2017, Volume 11, Issue 4,   Pages 570-575 doi: 10.1007/s11684-017-0552-5

Abstract:

China recently instituted a two-child policy in response to its aging population, declining workforce and demographic dividend, and the need to develop asocial economy. Additionally, women generally delay having a second child because of the overwhelming pressure in their lives. With the improvements in assisted fertility technologies in recent years, the number of elderly women attempting to bear children has increased. The quality of woman’s eggs and a man’s sperm declined dramatically with increasing age, leading to an increased risk of pregnancy-related complications among older women. Therefore, the types of fertility problems experienced by elderly females must be provided with considerable attention by obstetricians. This commentary article focuses on the medical problems faced by older second-child pregnant women. This work discusses their increased rates of infertility, spontaneous abortion, fetal malformation, gestational diabetes, cesarean section, placenta previa, postpartum hemorrhage, postpartum depression, and hypertensive disorders, which complicate pregnancy.

Stem cell gene therapy: the risks of insertional mutagenesis and approaches to minimize genotoxicity

Chuanfeng Wu, Cynthia E. Dunbar

Frontiers of Medicine 2011, Volume 5, Issue 4,   Pages 356-371 doi: 10.1007/s11684-011-0159-1

Abstract: Virus-based vectors are widely used in hematopoietic stem cell (HSC) gene therapy, and have the ability to integrate permanently into genomic DNA, thus driving long-term expression of corrective genes in all hematopoietic lineages. To date, HSC gene therapy has been successfully employed in the clinic for improving clinical outcomes in small numbers of patients with X-linked severe combined immunodeficiency (SCID-X1), adenosine deaminase deficiency (ADA-SCID), adrenoleukodystrophy (ALD), thalassemia, chronic granulomatous disease (CGD), and Wiskott-Aldrich syndrome (WAS). However, adverse events were observed during some of these HSC gene therapy clinical trials, linked to insertional activation of proto-oncogenes by integrated proviral vectors leading to clonal expansion and eventual development of leukemia. Numerous studies have been performed to understand the molecular basis of vector-mediated genotoxicity, with the aim of developing safer vectors and lower-risk gene therapy protocols. This review will summarize current information on the mechanisms of insertional mutagenesis in hematopoietic stem and progenitor cells due to integrating gene transfer vectors, discuss the available assays for predicting genotoxicity and mapping vector integration sites, and introduce newly-developed approaches for minimizing genotoxicity as a way to further move HSC gene therapy forward into broader clinical application.
