Background: ACKR2 is an atypical chemokine receptor that plays a significant role in regulating inflammation by binding to inflammatory CC chemokines and facilitating their degradation. Previous findings suggest that the genetic absence of ACKR2 leads to heightened tumor growth in inflammation-driven models. Conversely, mice lacking ACKR2 exhibit protection against lung metastasis in melanoma and breast cancer models.
View Article and Find Full Text PDFResearch on the cerebellum and its functional organization has significantly expanded over the last decades, expanding our comprehension of its role far beyond motor control, including critical contributions to cognition and affective processing. Notably, the cerebellar lateralization mirrors contralateral brain lateralization, a complex phenomenon that remains unexplored, especially across different stages of life. The present work aims to bridge this gap by providing a comprehensive scoping review of the lateralization of motor, cognitive, and affective functioning within the cerebellum across the lifespan.

Investigating the colonization and outgrowth of brain metastases is challenging given the complexity of the organ, tissue sampling difficulty, and limited experimental models. To address this challenge, we employed a strategy to analyze the metastatic niche in established lesions, based on the release of a cell-penetrating mCherry tag from labeled tumor cells to neighboring niche cells, using different brain metastasis mouse models.

Botulinum neurotoxin type A (BoNT-A) has been shown to improve spasticity, but the optimal timing of its application remains unclear. While several predictors of upper limb PSS are known, their utility in clinical practice in relation to BoNT-A treatment has yet to be fully elucidated.

This involves a series of interconnected changes in the cellular landscape, spatial organization, and extracellular matrix composition. However, assessing these alterations simultaneously is challenging from a spatial perspective, due to the limitations of current high-dimensional imaging techniques and the extent of intratumoral heterogeneity over large lesion areas.
View Article and Find Full Text PDFBrain metastasis (BrM) is a common malignancy, predominantly originating from lung, melanoma, and breast cancers. The vasculature is a key component of the BrM tumor microenvironment with critical roles in regulating metastatic seeding and progression. However, the heterogeneity of the major BrM vascular components, namely endothelial and mural cells, is still poorly understood.

Methods: Multicenter/retrospective/observational study. A database was sent to all the Italian vascular surgeries to collect all the patients operated on for CLTI in 2019.
Purpose: This study reports the outcomes from a Multicenter Registry on unibody stent-graft system for the treatment of spontaneous infrarenal acute aortic syndrome (MURUSSIAS registry).
Materials And Methods: The retrospective MURUSSIAS registry included spontaneous infrarenal acute aortic dissection (IAAS) managed with the unibody stent-graft system (AFX endovascular AAA system; Endologix Inc., Irvine, California) outside the current instruction for use.
Background: To investigate the effects of the COVID-19 lockdowns on the vasculopathic population. Methods: The Divisions of Vascular Surgery of the southern Italian peninsula joined this multicenter retrospective study. Each received a 13-point questionnaire investigating the hospitalization rate of vascular patients in the first 11 months of the COVID-19 pandemic and in the preceding 11 months.

We planned an endovascular procedure of correction consisting of a proximal extension through two covered stent grafts deployed into the previous Nellix stent grafts, with associated triple chimney. However, 3 months later, he had a further 5 mm aneurysmal sac enlargement.

The management remains controversial: elective simultaneous TEVAR and EVAR could increase morbidity due to increased aortic coverage during a single procedure, longer operative times, increased blood loss, and greater contrast exposure.

The presence of an abscess requires urgent drainage and specific antibiotic therapy. Patients with critical limb ischemia need revascularization and, subsequently the intervention of a plastic surgeon is often required in cases of exposure of tendons and ligaments.

He was previously submitted to kissing iliac arteries stent for iliac aneurysms. An urgent CT scan showed a type Ia and a type IIIb endoleaks with left common iliac artery enlargement, occlusion of both hypogastric arteries and inferior mesenteric artery, and a severe stenosis of the right iliac external artery.

To prevent bypass exposure and subsequent complications, physicians recur to reoperation, antibiotic therapy, advanced dressing and vacuum-assisted closure therapy. To improve the process of wound healing, cord blood platelet gel can be used to fill deep and large wounds.

From January 2016 through December 2018, twenty-seven patients (23 male, 4 female, mean age of 57 years) affected by type B dissection (n = 13 [48.2%]), thoracic aneurysm (n = 9 [33.

Pair sources based on spontaneous four-wave mixing in silicon microring resonators usually employ expensive external tunable lasers to compensate for ambient fluctuations; adopting self-pumped configurations, instead, lifts the need for such external source. Here we demonstrate the emission of time-energy entangled photon pairs at telecom wavelengths from a silicon self-pumped ring, obtaining a Franson interference fringe with 93.

The gold standard of treatment is represented by open surgical repair (OSR). Patients judged unfit for OSR could be submitted to fenestrated endovascular aortic repair (FEVAR) or the chimney technique.

The innominate artery lesions represent the most common site of injury after the aortic isthmus distal to the left subclavian artery. Injuries are usually located at the origin of the vessel from the aortic arch, especially in patients with bovine aortic arch.

We realize this by using a source of heralded single photons, then splitting the resulting single photon state and letting it propagate over distances much larger than the experimental time resolution times the speed of light c. We find no additional delay within our accuracy and set a lower limit for the speed of collapse of the quantum state to 1550c.

Eighteen patients with a definite diagnosis of ALS received microinjections of hNSCs into the gray matter tracts of the lumbar or cervical spinal cord. Patients were monitored before and after transplantation by clinical, psychological, neuroradiological, and neurophysiological assessment.
