Gram-positive bacteria pose significant threats to human health, necessitating the development of targeted bacterial detection and eradication strategies. Nevertheless, current approaches often suffer from poor targeting specificity. Herein, the study utilizes purple rice lixivium to synthesize biomass carbon dots (termed BCDs) with wheat germ agglutinin-like residues for precisely targeting Gram-positive bacteria.

Biliary and pancreatic tract stenosis are hallmark symptoms in pancreaticobiliary diseases, transcending malignancy. Endoscopic techniques are pivotal for biliary/pancreatic drainage; however, challenging scenarios arise when attempting to pass a guidewire (GW) through obstruction. Cholangioscopy-assisted GW placement has proven valuable, but challenges persist in its execution, particularly in maneuvering the GW through cholangioscopy.

We report a case of computed tomography-guided percutaneous radiofrequency ablation of a bleeding renal angiomyolipoma. Radiofrequency ablation was performed as an alternative to partial nephrectomy and super-selective renal artery embolization for ruptured renal angiomyolipoma with slow persistent bleeding in a patient with elevated serum creatinine levels and other comorbidities. Computed tomography-guided radiofrequency ablation successfully stopped the active hemorrhage and did not affect long-term renal function during the 3-year follow period.

Background: Arteriovenous malformation (AVM) and developmental venous anomaly (DVA) rarely coexist. Developing a surgical strategy to treat this co-occurrence is difficult due to the unclear pathogenesis. We report the use of super-selective digital subtraction angiography (DSA) and Three-dimensional (3D) rotational digital subtraction venography (DSV) to develop a surgical strategy for complex AVM draining into a DVA.

Department of Neurosurgery, Kobe University Graduate School of Medicine, Kobe, Japan.
Background: Cavernous sinus dural arteriovenous fistula (CSDAVF) is an abnormal arteriovenous connection involving the dura mater within or adjacent to the wall of the cavernous sinus. While cases with superior ophthalmic vein drainage and ocular symptoms are typical, we report a rare case of CSDAVF draining into the perimedullary vein of the medulla oblongata and spinal cord and causing cerebellar ataxia and myelopathy as the initial presentation.
Case Description: A 73-year-old man presented with vertigo and rapidly progressing gait disturbance.
