Background: Intraductal papillary mucinous neoplasms (IPMNs) are premalignant cystic neoplasms of the pancreas (CNPs), which can progress to invasive IPMN and pancreatic cancer. The available literature has shown controversial results regarding prognosis and clinical outcomes after the resection of invasive IPMN.

Aims: This study aims to characterize the oncologic outcomes and metastatic progression pattern after the resection of non-metastatic invasive IPMN.

There is a lack of training curricula and educational concepts for robotic-assisted surgery (RAS). It remains unclear how surgical residents can be trained in this new technology and how robotics can be integrated into surgical residency training. The conception of a training curriculum for RAS addressing surgical residents resulted in a three-step training curriculum including multimodal learning contents: basics and simulation training of RAS (step 1), laboratory training on the institutional robotic system (step 2) and structured on-patient training in the operating room (step 3).

Ubiquitination is a posttranslational modification that is crucial for the dynamic regulation of diverse signaling pathways. To enhance our understanding of ubiquitination-mediated signaling, we generated a new class of bispecific antibodies that combine recognition of ubiquitination substrates and specific polyubiquitin linkages. RIP1-K63 and RIP1-linear (Lin) linkage polyubiquitin bispecific antibodies detected linkage-specific ubiquitination of the proinflammatory kinase RIP1 in cells and in tissues and revealed RIP1 ubiquitination by immunofluorescence.

Gold nanoparticles are frequently employed as nanozyme materials due to their capacity to catalyze various enzymatic reactions. Given their plasmonic nature, gold nanoparticles have also found extensive utility in chemical and photochemical catalysis owing to their ability to generate excitons upon exposure to light. However, their potential for plasmon-assisted catalytic enhancement as nanozymes has remained largely unexplored due to the inherent challenge of rapid charge recombination.

Virtual reality (VR) is an increasingly available resource with numerous applications to medical education, and as a teaching tool has been widely validated in the literature. Photogrammetry, the process of overlapping two-dimensional (2D) photographic images of three-dimensional (3D) objects to create a 3D image or "model," can be used in conjunction with VR to create pedagogically sound learning modules for anatomy education. However, to date, there has not been a detailed description of the process of developing and implementing an in-house VR tool to supplement anatomy instruction.

XIAP is a caspase-inhibitory protein that blocks several cell death pathways, and mediates proper activation of inflammatory NOD2-RIP2 signaling. XIAP deficiency in patients with inflammatory diseases such as Crohn's disease, or those needing allogeneic hematopoietic cell transplantation, is associated with a worse prognosis. In this study, we show that XIAP absence sensitizes cells and mice to LPS- and TNF-mediated cell death without affecting LPS- or TNF-induced NF-κB and MAPK signaling.

Background: Gastrointestinal stromal tumors (GIST) are rare mesenchymal tumors. They are most frequently located in the stomach but are also found in the esophagus and the gastroesophageal junction (GEJ). Information regarding the prognostic factors associated with upper gastrointestinal GIST is still scarse.

Introduction: 2−8% of all gastric cancer occurs at a younger age, also known as early-onset gastric cancer (EOGC). The aim of the present work was to use clinical registry data to classify and characterize the young cohort of patients with gastric cancer more precisely. Methods: German Cancer Registry Group of the Society of German Tumor Centers—Network for Care, Quality and Research in Oncology (ADT)was queried for patients with gastric cancer from 2000−2016.

Article Synopsis
  • A study was conducted to assess the effects of virtual reality (VR) on pain tolerance during ice immersion procedures, focusing on biometric data and subjective experiences.
  • In a controlled trial with 156 healthy volunteers, participants used VR or a control method while immersing one hand in ice water to see which they could tolerate longer.
  • Results showed that those using VR were 64% less likely to withdraw from the ice and reported significantly lower pain levels compared to the control group, although sympathetic arousal (measured by SCRD) increased similarly for both groups over time.

Study Objective: HRAD± was developed to quickly evaluate pediatric preprocedural affect and cooperativity during mask induction of anesthesia and peripheral intravenous (PIV) placement. HRAD± represents: Happy, Relaxed, Anxious, Distressed, with a yes/no answer to cooperativity. The primary aim of this study was to compare HRAD± to previously published scales.

Various forms of cell death have been identified over the last decades with each relying on a different subset of proteins for the activation and execution of their respective pathway(s). In addition to the three best characterized pathways-apoptosis, necroptosis, and pyroptosis-other forms of regulated cell death including autophagy-dependent cell death (ADCD), mitochondrial permeability transition pore (MPTP)-mediated necrosis, parthanatos, NETosis and ferroptosis, and their relevance for organismal homeostasis are becoming better understood. Importantly, it is increasingly clear that none of these pathways operate alone.

The ubiquitin system is complex, multifaceted, and is crucial for the modulation of a vast number of cellular processes. Ubiquitination is tightly regulated at different levels by a range of enzymes including E1s, E2s, and E3s, and an array of DUBs. The UPS directs protein degradation through the proteasome, and regulates a wide array of cellular processes including transcription and epigenetic factors as well as key oncoproteins.

Receptor-interacting protein 1 (RIP1; RIPK1) is a key regulator of multiple signaling pathways that mediate inflammatory responses and cell death. TNF-TNFR1 triggered signaling complex formation, subsequent NF-κB and MAPK activation and induction of cell death involve RIPK1 ubiquitination at several lysine residues including Lys376 and Lys115. Here we show that mutating the ubiquitination site K376 of RIPK1 (K376R) in mice activates cell death resulting in embryonic lethality.

This case series examines interactive AR during minor otolaryngologic procedures. Although VR has been successfully used for pediatric vascular access, removing children from comforting people in the real world has resulted in patient anxiety. AR offers a potential advantage, utilizing distracting holographic images when patients maintain eye contact with parents.

Purpose: To investigate the performance of radiography and single-photon emission computed tomography/computed tomography (SPECT/CT) in painful hip arthroplasty regarding loosening and arthroplasty survival.

Methods: Radiography and SPECT/CT reports of 249 painful hip arthroplasties of 191 patients were reviewed. Positive imaging was defined if loosening, infection, and polyethylene wear were found, indicating the need for arthroplasty exchange.

Background: Vascular access is a minor procedure that is associated with reported pain and fear in pediatric patients, often resulting in procedural incompliance. Virtual reality has been shown to be effective in adult populations for reducing pain and anxiety in various medical settings, although large studies are lacking in pediatrics.

Aims: The primary aim was to determine whether pain would be reduced in pediatric patients using virtual reality undergoing vascular access.

Anoikis is a form of apoptosis induced by cell detachment. Integrin inactivation plays a major role in the process but the exact signalling pathway is ill-defined. Here we identify an anoikis pathway using gliotoxin (GT), a virulence factor of the fungus Aspergillus fumigatus, which causes invasive aspergillosis in humans.

Proper regulation of cell death signaling is crucial for the maintenance of homeostasis and prevention of disease. A caspase-independent regulated form of cell death called necroptosis is rapidly emerging as an important mediator of a number of human pathologies including inflammatory bowel disease and ischemia-reperfusion organ injury. Activation of necroptotic signaling through TNF signaling or organ injury leads to the activation of kinases receptor-interacting protein kinases 1 and 3 (RIP1 and RIP3) and culminates in inflammatory cell death.
