Pathological Copper Overload Reprograms SOD1 Activation via COMMD1 to Promote Senescence and Fibrosis

Advanced Science, Volume 13, Issue 54, 28 September 2026.
This study uncovers a previously unrecognized copper‐COMMD1‐SOD1 regulatory axis, revealing that pathological copper overload paradoxically suppresses SOD1 activity by promoting COMMD1‐dependent disruption of SOD1 homodimerization. These findings redefine the regulatory role of copper in SOD1 biology and provide novel mechanistic insight into the ...

Scintigraphic Demonstration of Urine Extravasation Secondary to Acute Ureteral Obstruction: A Case Report and Some Considerations about Acute Ureteral Obstruction [PDF]

, 2006
Acute ureteral obstruction produces renal damage and complications that are proportional to the severity and length of the obstruction. Anatomic diagnosis of the obstruction may be insufficient to manage the patient.

Co‐Occurring Non‐Cardiac Congenital Anomalies Among Cases With Congenital Heart Defects

American Journal of Medical Genetics Part A, Volume 200, Issue 9, Page 1953-1972, September 2026.
ABSTRACT Cases with congenital heart defects (CHD) often have other associated anomalies. The aim of this investigation was to assess the prevalence and the types of co‐occurring anomalies in CHD in a well‐defined population. The anomalies co‐occurring with CHD were ascertained in all live births, stillbirths and terminations of pregnancy for fetal ...

Robotic‐assisted laparoscopic ureteral reimplantation using the LUAA technique: VCUG‐confirmed outcomes, learning curve and CUSUM analysis

BJUI Compass, Volume 7, Issue 9, September 2026.
Abstract Objective To delineate the learning curve of robotic‐assisted laparoscopic ureteral reimplantation (RALUR) through the LUAA extravesical technique, we characterized efficacy and safety outcomes throughout surgical proficiency development using cumulative sum (CUSUM) analysis and perioperative trifecta outcomes.

Clinical Benefit of Pembrolizumab in Lynch Syndrome‐Associated Advanced Ovarian Cancer With Germline MSH6 Variant: A Case Report

Clinical Case Reports, Volume 14, Issue 9, September 2026.
ABSTRACT This case highlights the importance of genetic evaluation during treatment in young patients with advanced ovarian cancer. Lynch syndrome caused by a germline MSH6 pathogenic variant was diagnosed during first‐line maintenance therapy, and pembrolizumab achieved a durable response in recurrent disease.

Giant Fetal Sacrococcygeal Teratoma: Prenatal Detection, Monitoring, and Postnatal Management—A Case Report and Literature Review

Clinical Case Reports, Volume 14, Issue 9, September 2026.
ABSTRACT Sacrococcygeal teratoma (SCT) is a rare congenital tumor arising from pluripotent cells at the base of the coccyx and is most often detected during antenatal imaging. In this case, a massive SCT was identified at 26 + 2 weeks during routine ultrasound.

Migration of a Ureteral Double‐J Catheter From the Inferior Vena Cava to the Right Atrium With Concomitant Iliac Vein Thrombosis: Successful Retrieval and Anticoagulation Therapy—A Case Report

Clinical Case Reports, Volume 14, Issue 9, September 2026.
ABSTRACT We report the case of a 67‐year‐old male who underwent ureteral catheter placement for a right ureteral stone. Two months later, the catheter had migrated into the inferior vena cava and subsequently into the right atrium. The catheter was successfully removed using a snare via the right femoral vein.
