Tailoring anaesthetic strategies for diabetes research: Acepromazine vs. medetomidine in Aachen minipigs.
PLoS One
January 2025
Medical Faculty Mannheim, Heidelberg University, Mannheim, Germany.
Pre-established anaesthetic protocols in animal models might unexpectedly interfere with the main outcome of scientific projects and therefore they need to account for the specific research goals. We aimed to optimize the anaesthetic protocol and animal handling strategies in a diabetes-related-study exemplifying how the anaesthetic approach must be adjusted for individual research targets. Aachen minipigs were used as a model to test long-lasting skin glucose sensors for diabetic human patients.

The objective of this study is to fabricate and develop hydroxypropyl methylcellulose (HPMC) hydrogel (HG)-based composite bone cements with incorporation of hydroxyapatite (HA), beta-tricalcium phosphate (β-TCP), and with/without polymethylmethacrylate (PMMA) for vertebroplasty. For animal study, twenty female Wister rats (250-300 g, 12 weeks of age) were divided into four groups including a two non-ovariectomy (NOVX) groups and two ovariectomy (OVX)-induced osteoporosis groups. Two prepared biocomposites including HG/β-TCP/HA and HG/β-TCP/HA/PMMA were injected into the tibial defects of both OVX and NOVX rats for evaluating in vivo osteogenesis after 12 weeks.

As many treatments kill tumor cells by inducing apoptosis, fluorescent probes that can detect apoptosis are crucial for effective feedback regarding tumor therapy outcomes (in particular, activatable probes for better imaging). Cathepsins are enzymes that are released from lysosomes into the cytoplasm during lysosomal membrane permeabilization-induced apoptosis of many tumor cells, making them potential biomarkers of apoptotic cells. Despite their potential, to the best of our knowledge, no cathepsin-activatable fluorescent probes have been reported for this purpose.

Introduction: In this study, a meta-analysis was conducted to investigate the therapeutic effect of Dapagliflozin (DAPA) on animals suffering from myocardial ischemia reperfusion compared to the group that did not receive treatment.
Methods: According to the inclusion and exclusion criteria two researchers performed the primary and secondary screening based on the title abstract and full text. After data extraction, meta-analysis was performed using STATA software.
DAMPs prognostic signature predicts tumor immunotherapy, and identifies immunosuppressive mechanism of pannexin 1 channels in pancreatic ductal adenocarcinoma.

Background: Damage-associated molecular patterns (DAMPs) induced by immunogenic cell death (ICD) may be useful for the immunotherapy to patients undergoing pancreatic ductal adenocarcinoma (PDAC). The aim of this study is to predict the prognosis and immunotherapy responsiveness of PDAC patients using DAMPs-related genes.
Methods: K-means analysis was used to identify the DAMPs-related subtypes of 175 PDAC cases.
