Age assessment by magnetic resonance imaging of the knee: a preliminary study.

The authors developed an original magnetic resonance imaging (MRI) staging system for epiphyseal fusion of growth plate maturation of the knee and evaluated its reliability and validity for age assessment of living individuals. A total of 290 MRI scans of the knee were reviewed retrospectively in patients aged from 10 to 30 years old (138 males, 152 females). Five original MRI stages were defined to assess the degree of maturation of the distal femoral and proximal tibial epiphyses.

De novo renal tumors arising in kidney transplants: midterm outcome after percutaneous thermal ablation.

Purpose: To retrospectively evaluate the midterm outcome of patients treated for primary renal cell carcinomas arising in kidney transplants with minimally invasive techniques.

Materials And Methods: The institutional review board of each participating institution approved this retrospective study and waived informed consent. This study was HIPAA compliant.

The RNA-binding protein ELAVL1/HuR is essential for mouse spermatogenesis, acting both at meiotic and postmeiotic stages.

Posttranscriptional mechanisms are crucial to regulate spermatogenesis. Accurate protein synthesis during germ cell development relies on RNA binding proteins that control the storage, stability, and translation of mRNAs in a tightly and temporally regulated manner. Here, we focused on the RNA binding protein Embryonic Lethal Abnormal Vision (ELAV) L1/Human antigen R (HuR) known to be a key regulator of posttranscriptional regulation in somatic cells but the function of which during gametogenesis has never been investigated.

[Urological and medical complications of renal transplant].

Medical complications from renal transplant (acute tubular necrosis, acute rejection, chronic rejection) are mainly imaged with Doppler ultrasound to first exclude vascular or urological causes for renal function impairment. Once these causes are excluded, imaging features are nonspecific and imaging is mainly used for follow-up and biopsy remains essential. Urological complications include postsurgical collections, urinary fistulas, obstructive uropathy, vesicoureteric reflux, infections and malignancies.
