The effects of growth hormone on corpus luteum of superovulated rats.

abstract：BACKGROUND:Ultrasonography is considered useful to distinguish between solid and cystic thyroid nodules and to stratify a nodule's risk of cancer as low, medium, or high. Ultrasound (US) elastography has been applied to study the hardness/elasticity of nodules to differentiate malignant from benign lesions. Elastograph...
