Small Bowel Obstruction Linked to Meckel's Diverticulum: A Rare Case.

Meckel's diverticulum (MD) is the most common congenital anomaly of the gastrointestinal tract, arising from incomplete obliteration of the vitelline duct. MD contains all layers of the intestinal wall and often remains asymptomatic. Gastrointestinal bleeding, bowel obstruction, and acute diverticulitis occur in a few cases.

Single Extracellular VEsicle Nanoscopy-Universal Protocol (SEVEN-UP): Accessible Imaging Platform for Quantitative Characterization of Single Extracellular Vesicles.

Extracellular vesicles (EVs), membrane-encapsulated nanoparticles shed from all cells, are tightly involved in critical cellular functions. Moreover, EVs have recently emerged as exciting therapeutic modalities, delivery vectors, and biomarker sources. However, EVs are difficult to characterize, because they are typically small and heterogeneous in size, origin, and molecular content.

Incidence and Risk Factors of Peri-Implantitis Over Time-A Prospective Cohort Study.

Aim: This prospective cohort study aimed to evaluate the incidence and risk/protective factors of peri-implantitis over time.

Methods: A university-representative cohort was evaluated at baseline and after a mean follow-up time of 3.9 years.

Structural basis for a nucleoporin exportin complex between RanBP2, SUMO1-RanGAP1, the E2 Ubc9, Crm1 and the Ran GTPase.

The human nucleoporin RanBP2/Nup358 interacts with SUMO1-modified RanGAP1 and the SUMO E2 Ubc9 at the nuclear pore complex (NPC) to promote export and disassembly of exportin Crm1/Ran(GTP)/cargo complexes. In mitosis, RanBP2/SUMO1-RanGAP1/Ubc9 remains intact after NPC disassembly and is recruited to kinetochores and mitotic spindles by Crm1 where it contributes to mitotic progression. Interestingly, RanBP2 binds SUMO1-RanGAP1/Ubc9 via motifs that also catalyze SUMO E3 ligase activity.
