Synaptic-vesicle (SV) recruitment is thought to maintain reliable neurotransmitter release during high-frequency signaling. However, the mechanism underlying the SV reloading for sustained neurotransmission at central synapses remains unknown. To elucidate this, we performed direct observations of SV reloading and mobility at a single-vesicle level near the plasma membrane in cerebellar mossy fiber terminals using total internal reflection fluorescence microscopy, together with simultaneous recordings of membrane fusion by capacitance measurements.

Article Synopsis
  • * An 80-year-old man presented with a hepatic mass, revealing a 38 × 34 mm cystic lesion with papillary growth during examination, complicating surgical determination due to its placement near the hepatic ducts.
  • * A peroral cholangioscopy confirmed the lesion's connection to the right hepatic duct, leading to a right hepatectomy, which resulted in a diagnosis of intraductal papillary neoplasm with invasive carcinoma; the patient's recovery was favorable with no signs of recurrence post

Background: Mucosal healing is the main treatment goal for Crohn's disease. In this situation, some patients have difficulty with endoscopic evaluation of the entire small intestine. Crohn's disease is closely associated with the gut microbiota, but the relationship between the microbiome and disease activity in the small intestine remains unclear.

Background And Aim: Microbiota have been associated with several diseases including colorectal cancer (CRC). This study aimed to evaluate the microbiota in early/invasive CRC utilizing stool and cytological brushes to determine differences in relative abundance (RA).

Methods: Colonoscopy patients referred for endoscopic submucosal dissection or previous to CRC surgery were prospectively enrolled.

A 44-year-old woman was referred to our hospital because of a cystic lesion in the pancreatic body that was found by computed tomography (CT) as a result of a screening for impaired liver function after the patient presented with a high fever in 2011. Trans-abdominal ultrasonography (US) revealed a 33-mm unilocular cyst within the pancreatic body and a 5-mm hypoechoic mass in the pancreatic neck. Contrast-enhanced CT showed a slight enhancement around the cyst and a mild dilation of the main pancreatic duct, but neither septum nor nodule was detected inside.

A 45-year-old woman visited our hospital due to upper left quadrant pain and melena. Colonoscopy revealed longitudinal ulcers in the transverse colon. The endoscopic findings and pathological examination of a biopsy specimen led to diagnosis of Crohn disease, and mesalazine was administered.

Continued exposure of endothelial cells to mechanical/shear stress elicits the unfolded protein response (UPR), which enhances intracellular homeostasis and protect cells against the accumulation of improperly folded proteins. Cells commit to apoptosis when subjected to continuous and high endoplasmic reticulum (ER) stress unless homeostasis is maintained. It is unknown how endothelial cells differentially regulate the UPR.
