Research on Enhancement of Toughness Performance in Polyurethane-Modified Epoxy Asphalt

Zhongwai Gonglu
To solve low toughness and high brittleness of epoxy asphalt under low-temperature conditions, in this study, polyether-type polyurethane (JMPU) and polyester-type polyurethane (JZPU) were employed to prepare modified epoxy asphalt.

Are Fertility Preservation Procedures Before Gonadotoxic Therapy and Hematopoietic Stem Cell Transplantation Feasible and Safe in Very Young Children? A Retrospective Cohort Study

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Fertility preservation (FP) is increasingly integrated into the care of pediatric patients exposed to gonadotoxic therapy or conditioning for hematopoietic stem cell transplantation (HSCT), yet perioperative data in infants and toddlers remain scarce.

Prevalence of 21 Physician‐Defined Severe Toxicities Following Childhood Acute Lymphoblastic Leukemia Treatment: Australian Retrospective Cohort Study

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Acute lymphoblastic leukemia (ALL) is the most common pediatric cancer, with an overall survival now surpassing 90% in developed countries. However, treatments are not without adverse effects. In this study, we apply the severe toxicity‐free survival (STFS) framework to determine the prevalence of 21 physician‐defined severe ...

Rational Use of Herbal Products in Pediatric Patients Treated With Anticancer Drugs in the European Union

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Introduction The use of herbal medical preparation (HMP) is rising among pediatric oncology patients, often to manage treatment‐related symptoms. Their effectiveness remains uncertain, and the risk of herb–drug interactions is underestimated.

Aging effect in nasal resistance.

Nippon Jibiinkoka Gakkai Kaiho, 1984
5歳から84歳までの鼻疾患,呼吸器疾患のない男女501例について,一方向流によるpassive anterior法にて鼻腔抵抗の測定を行い,5歳から16歳までの各年齢および15歳以上の6つの年齢群ごとの測定値を示し,年齢と鼻腔抵抗の変化につき検討を加え,次のような結果を得た.1) 5歳から16歳までの抵抗の変化は,a) 8歳までの抵抗の高い時期,b) それに続き11歳頃までの比較的急激に抵抗が低下する時期,およびc) それ以後の抵抗の変動が認められる時期の3つに分けられる.a)においてはアデノイドの存在が,b)においては鼻腔の大きさの増大とアデノイドの消退が,c)においては鼻腔や鼻甲介の発育の不均衡と自律神経系の影響が考えられた.2) 20歳以後の抵抗の変化には次の2つの特徴がみられた.a ...
