Structural design and property regulation of organic polymers for photocatalytic synthesis of H2O2

InfoScience, EarlyView.
Photocatalytic synthesis of H2O2 offers a sustainable approach. Photocatalytic efficiency depends critically on interfacial electron transfer kinetics and spatial charge separation. Herein, we systematically analyze key factors governing photogenerated carrier dynamics and propose engineered strategies to optimize performance, thereby providing design ...

Undiagnosed patent foramen ovale: a rare cause for acute pulmonary embolism and cryptogenic stroke

Asian Journal of Internal Medicine
Patent foramen ovale (PFO) is a congenital cardiac anomaly found in 25-30% of the population. Though often asymptomatic, it may lead to paradoxical embolism and cryptogenic stroke.

Complete Resolution of Right Atrial Free-floating Thrombus After Warfarin Therapy in Chemotherapy-induced Cardiomyopathy: a Case Report [PDF]

, 2016
Free-floating right heart thrombus is a rare phenomenon and has dismal rognosis. The optimal management of free-floating right thrombus remains controversial with no clear consensus. We present a case of right atrial free-floating thrombus in 56-year-old

Prominent Chiari Network as a Cause of Cyanosis in Infants: A Case Report and Implications for Pediatric Cardiology Practice

Journal of Clinical Ultrasound, EarlyView.
A prominent Chiari network can cause cyanosis in infants by inducing a positional right‐to‐left atrial shunt. Accurate diagnosis enabled conservative management, delaying surgery until optimal conditions. This case emphasizes the importance of echocardiographic evaluation in differentiating cyanosis mechanisms to guide appropriate treatment in ...

Pulmonary Arteriovenous Malformation can be Associated with Embolic Stroke of Undetermined Source (ESUS)

European Journal of Case Reports in Internal Medicine, 2019
Pulmonary arteriovenous malformations (PAVMs) are rare vascular anomalies. Alternative designations are pulmonary arteriovenous fistulae or aneurysms. Although mostly asymptomatic, PAVMs can cause respiratory symptoms due to right-to-left shunt.

May-Thurner Syndrome as a Rare Cause of Paradoxical Embolism in a Patient with Patent Foramen Ovale

Case Reports in Cardiology, 2018
May-Thurner syndrome is an underrecognized anatomical variant that can lead to increased propensity for venous thrombosis in the lower extremities. We present a case of a 67-year-old female who presented with transient ischemic attack.

Paradoxical Cerebral Fat Embolism in an Adolescent PLHA: A Convergence of Trauma, ART Induced Hypercoagulability, and Septal Heart Defect

Case Reports in Clinical Practice
Fat embolism syndrome (FES) is a life-threatening complication following long bone fractures, primarily affecting the pulmonary circulation. However, cerebral fat embolism (CFE) is a rare yet severe variant that can occur when fat emboli bypass the ...

Successful outcome of massive carbon dioxide embolism during laparoscopic hepatectomy

Laparoscopic, Endoscopic and Robotic Surgery, 2020
Carbon dioxide embolism is a rare but severe complication of laparoscopic hepatectomy. We reported a case of massive carbon dioxide embolism that developed into a rare paradoxical gas embolism during laparoscopic hepatectomy and resulted in reduced ...

Nanotechnology in Skin Cancer Therapy: Recent Progress in Targeted Delivery

The Kaohsiung Journal of Medical Sciences, EarlyView.
ABSTRACT Skin cancer, encompassing melanoma and non‐melanoma types, remains a significant public health concern globally. Conventional therapies—such as surgery, radiotherapy, chemotherapy, and immunotherapy—are constrained by poor skin penetration, systemic toxicity, and high recurrence rates.

Retrograde cerebral embolism and pulmonary embolism caused by patent ductus arteriosus: a case report

Journal of Cardiothoracic Surgery
Background Although rare, paradoxical embolism sometimes occurs with patent ductus arteriosus (PDA). This study presents a case of PDA-associated paradoxical embolism with acute ischemic stroke (AIS) and pulmonary embolism (PE) following thoracoscopic ...
