Application of ultrasound microbubble contrast to evaluate the effect of sitaxentan on renal microvascular perfusion in beagles undergoing cardiopulmonary bypass
CONCLUSIONS: Ultrasound microbubble contrast could be effectively used to evaluate renal microvascular perfusion peri-CPB in beagles, which was prone to decrease and could be improved via pretreatment with sitaxentan.PMID:37599525 | DOI:10.3233/CH-221600

An adapted liver perfusion in a shark species, < em > Squalus suckleyi < /em > : investigation of energy mobilization
Am J Physiol Regul Integr Comp Physiol. 2023 Aug 21. doi: 10.1152/ajpregu.00132.2023. Online ahead of print.ABSTRACTThe liver is an essential energy storage organ in vertebrates. In teleosts and elasmobranchs, previous studies examining hepatic energy balance have used isolated hepatocytes. While these studies have been informative the high fat content in the elasmobranch liver limits isolation of hepatocytes and therefore the utility of this method to understand hepatic metabolic processes. In the present study we developed an in situ liver perfusion in the North Pacific spiny dogfish, Squalus suckleyi. Perfusions were co...

Extended Right Hepatectomy to Inferior Vena Cava Under Total Vascular Exclusion, Veno-Venous Bypass and In Situ Hypothermic Perfusion of the Future Liver Remnant
CONCLUSIONS: Total vascular exclusion with veno-venous bypass and in-situ liver hypothermic perfusion increases the safety of major liver resection requiring complex vascular reconstruction.1,2 TVE under VVB and HP of the future liver remnant is used at our institution when: (1) TVE will last more than 30 min; (2) vascular reconstruction is needed; (3) in the presence of venous obstruction; (4) in the presence of injured liver parenchyma; and (5) in the presence of cardiovascular comorbidities.PMID:37598116 | DOI:10.1245/s10434-023-14182-z

Acute ischemic stroke: The role of emergency carotid endarterectomy in isolated extracranial internal carotid artery occlusion
CONCLUSIONS: Emergency CEA in isolated eICA occlusion has proved to be a safe and effective treatment option in selected patients. CT perfusion, imaging the ischemic penumbra and quantifying the tissue suitable for reperfusion, offers a valid support in the diagnostic-therapeutic workup. Indeed, we can infer that the area of the ischemic penumbra is directly proportional to the margin of clinical improvement after revascularization, supposing that the appropriate intervention timing is respect.PMID:37594376 | DOI:10.1177/17085381231192712

Indications for replantation and factors that predict success
Eur J Orthop Surg Traumatol. 2023 Aug 18. doi: 10.1007/s00590-023-03671-2. Online ahead of print.ABSTRACTSince the advent of replantation techniques, there has been uneven progress in terms of success-even considering whether success is defined as continued perfusion of the digit or long term functional outcomes. Early enthusiasm and success have not been maintained despite increasing familiarity with microsurgical techniques and greater understanding of how to optimize outcomes for the individual components of replantation such as tendon repair, nerve repair, and osteosynthesis. Practitioners participating in the care of ...

Pannexin 1 Modulates Angiogenic Activities of Human Endothelial Colony-Forming Cells Through IGF-1 Mechanism and Is a Marker of Senescence
CONCLUSIONS: Panx1 expression is upregulated in human ECFCs/EPCs with replication-induced senescence and during aging. Angiogenic potential of senescent ECFCs is improved by Panx1 reduction through increased IGF-1 production via activation of the FAK-ERK axis following calcium influx reduction. Our findings provide new strategies to evaluate EPC activities and rejuvenate senescent EPCs for therapeutic angiogenesis.PMID:37589139 | DOI:10.1161/ATVBAHA.123.319529
