Cattle production by intracytoplasmic sperm injection into oocytes vitrified after ovum pick-up.

Intracytoplasmic sperm injection (ICSI), oocyte vitrification after ovum pick-up (OPU), and in vitro maturation are reproductive technologies with incredible potential for efficient cattle production. However, the developmental competence of embryos produced by ICSI using vitrified OPU oocytes remains unknown. Here, we aimed to evaluate the developmental competence of these embryos from the early embryo period to full term.

Does Transport by a Doctor Helicopter Affect Blood Pressure in Stroke Patients?

Objective: Herein we investigate whether transportation by doctor helicopter (DH) affects blood pressure (BP) in stroke patients.

Methods: A total of 119 stroke patients treated by the DH between April 2015 and March 2019 were analyzed. The average BP before and after admission to the DH was compared for all stroke patients.

Factors Associated with Poor Outcomes in Patients with Mild or Moderate Acute Subdural Hematomas.

The factors influencing the outcomes of mild/moderate acute subdural hematoma (ASDH) are still unclear. Retrospective analyses were performed to identify such factors. The medical records of all patients who were admitted to Saiseikai Shiga Hospital with mild (Glasgow Coma Scale [GCS] score of 14-15) or moderate (GCS score of 9-13) ASDH between April 2008 and March 2017 were reviewed.

Aplastic or Twig-Like Middle Cerebral Artery Presenting with Intracerebral Hemorrhage During Pregnancy: Report of Two Cases.

Background: An aplastic or twig-like middle cerebral artery (Ap/T-MCA) is a rare congenital anomaly that can present with both ischemic and hemorrhagic stroke. The etiology of this pathology has remained unclear. Here, we report 2 cases of intracerebral hemorrhage (ICH) owing to an Ap/T-MCA in pregnant patients.

Shorter pregnant women restrained in the rear seat of a car are at risk for serious neck injuries: Biomechanical analysis using a pregnant crash test dummy.

Introduction: When considering seat belt contacts to the neck in pregnant woman of shorter height sitting in the rear seat of a vehicle, subsequent injuries after a collision must be understood in the context of both maternal and fetal outcomes. To determine likely injuries to a pregnant woman sitting in the rear seat, we determined the kinematics of a "pregnant" crash test dummy by measuring neck compression forces and biomechanical parameters acting on the head and neck.

Methods: Sled tests using a shorter-height pregnant woman crash test dummy (Maternal Anthropometric Measurement Apparatus, ver.
