Pain is a persistent symptom of Rheumatoid Arthritis, and the K/BxN serum transfer model recapitulates both association dissociation between pain joint inflammation in RA. Furthermore, this features monocyte/macrophage infiltration joints lumbar dorsal root ganglia (DRG), where these immune cells are close to nociceptive neurons. We focussed on CX3CR1-monocyte/macrophage trafficking show that at peak paw swelling associated with nociception, CX3CR1 deletion altered neither nor macrophage...

Neuropathic pain remains poorly managed by current therapies, highlighting the need to improve our knowledge of chronic mechanisms. In neuropathic models, dorsal root ganglia (DRG) nociceptive neurons transfer miR-21 packaged in extracellular vesicles macrophages that promote a proinflammatory phenotype and contribute allodynia. Here we show conditional deletion DRG was coupled with lack upregulation chemokine CCL2 after nerve injury reduced accumulation CCR2-expressing macrophages, which...

Effective reepithelialization after injury is essential for correct wound healing. The upregulation of keratinocyte α3β1 integrin during suggests that this adhesion molecule involved in healing; however, its precise role process unknown. We have shown here retarded Itga3–/– mouse skin wounds due predominantly to repressed TGF-β1–mediated responses. Specifically, expression the inhibitor TGF-β1–signaling Smad7 was elevated keratinocytes. Indeed, vivo blockade increased rate and WT similar...

We report a female patient with situs inversus, dextrocardia, complex heart malformation, hydrocephalus due to aqueductal stenosis, and abnormal ultrastructure of the respiratory epithelium cilia. Several animal models this disorder implicate ciliary function in genesis hydrocephalus, 11 patients were previously reported syndrome primary dyskinesia. Primary dyskinesia–associated stenosis should be considered as possible cause for fetal or neonatal if heterotaxy, malformations, and/or...

Musculoskeletal chronic pain is prevalent in individuals with Alzheimer's disease (AD); however, it remains largely untreated these patients, raising the possibility that mechanisms are perturbed. Here, we utilise TASTPM transgenic mouse model of AD K/BxN serum transfer inflammatory arthritis. We show male and female WT mice, allodynia associated a distinct spinal cord microglial response characterised by TLR4-driven transcriptional profile upregulation P2Y12. Dorsal horn nociceptive...

Abstract Laminins are expressed highly in blood vessel basement membranes and have been implicated angiogenesis. α6β1‐ α6β4‐integrins major receptors for laminins endothelial cells, but the precise role of α6‐integrin tumour angiogenesis is not clear. We show that vessels human invasive ductal carcinoma breast decreased expression α6‐integrin‐subunit when compared with normal tissue. These data suggest a decrease cells associated To test whether loss subunit affects growth angiogenesis, we...

Introduction: The best route of delivery for the term breech fetus is still controversial. We aim to compare maternal and neonatal outcomes between vaginal cesarean deliveries.Material Methods: Multicentric retrospective cohort study singleton fetuses delivered vaginally or by elective section from January 2012 - October 2014. Primary were morbidity mortality.Results: Sixty five compared 1262 cesarean. Nulliparous women more common in group (69.3% vs 24.6%; p < 0.0001). Gestational age at...

Parathyroid cysts are rare lesions of the cervical region and less frequently mediastinum. They occur mostly in women usually asymptomatic. generally fourth fifth decades life mainly non-functioning. commonly present as a neck mass that is found incidentally during surgery or imaging test. Its importance lies difficulty diagnosis, often confusing itself with thyroid pathology. The diagnosis made intraoperatively, confirmed by histopathological examination. aim this paper to report case...

Paraovarian/paratubal cysts constitute about 10% of adnexal masses and are usually small asymptomatic. A huge paratubal cyst complicated by torsion is a rare cause acute low abdominal pain.We report the case an obese 31-year-old nulliparous woman who presented with large pelvic causing ovarian torsion. The size mass (~25 cm) caused pain, obesity led to explorative laparotomy, which showed central abdominal-pelvic arising from right adnexa. Cystectomy was technically impossible, so all adnexa...

Vaccination arises as cornerstone this fight against 2019 (COVID-19), though new challenges have emerged with it. Anaphylactic reactions to vaccines are very rare, occurring at a rate 1.31 per million doses administered [1]. Reports on mRNA Pfizer-BioNTech SARS-CoV-2...
