Background: Vascular endothelial growth factor (VEGF) expression seems to be associated with worse overall survival in patients with head and neck squamous cell carcinoma. The purposes of this study were to assess the prognostic values of the immunohistochemical expression of VEGF and vascular endothelial growth factor receptor-2 (VEGFR-2) in a cohort of patients with operable advanced laryngeal cancer who had been treated with induction chemotherapy.
Methods: VEGF and VEGFR-2 expression in the malignant cells was quantified by an enzyme immunosorbent assay in a retrospective series.
Results: Fifty-nine patients were included in this study. We found moderate to high VEGF expression in 61% of patients and none to low expression in 39%. VEGFR-2 expression was moderate to high in 58% of patients and was none to low in 42%. The probability of a complete response to induction chemotherapy was significantly higher in patients with none to low VEGF expression (74% vs 40%; p = .02).
Conclusion: VEGF expression seems to be a significant predictor of complete response to induction chemotherapy.

Department of Ophthalmology and Visual Sciences, University of Illinois at Chicago, Chicago, 60612, USA.
Purpose: To describe a patient with Coats disease with an atypical presentation of neovascular glaucoma and vitreous hemorrhage.
Observations: A 15-year-old male presented with five days of pain, redness, and swelling and was found to have neovascular glaucoma in his right eye. Further evaluation revealed Coats disease stage 3AI with a subtotal exudative retinal detachment inferiorly, telangiectatic vessels, and vitreous hemorrhage.
P-, E-, and H-cadherins differ in their relationships with coronary stenosis, cardiovascular outcomes, and unplanned recurrent revascularization.

Background And Aims: Cadherins are adhesion proteins, and their dysregulation may result in the development of atherosclerosis, plaque rupture, or lesions of the vascular wall. The aim of the present study was to detect the associations of cadherins-P, -E, and -H, with atherosclerosis and pathological cardiovascular conditions.
Methods And Results: The present study with 3-year follow up evaluated atherosclerosis and fasting levels of P-, E-, and H-cadherins in the serum samples of 214 patients in a hospital setting.
African-American women have a maternal mortality rate approximately three times higher than European-American women. This is partially due to hypertensive disorders of pregnancy, including preeclampsia. Fetal high-risk genotype increases preeclampsia risk, although mechanisms remain elusive.

We sought to understand the spatially-anchored regulation and transition of endothelial and mesangial cells from health to injury in DKD. From 74 human kidney samples, an integrated multi-omics approach was leveraged to identify cellular niches, cell-cell communication, cell injury trajectories, and regulatory transcription factor (TF) networks in glomerular capillary endothelial (EC-GC) and mesangial cells.

Recent findings of ectopic expression of LEC markers including Prospero Homeobox 1 (PROX1), a master regulator of lymphatic differentiation, and the vascular permeability marker Plasmalemma Vesicle Associated Protein (PLVAP), in certain glioblastoma and brain arteriovenous malformations (AVMs), has prompted investigation into their roles in cerebrovascular malformations, tumor environments, and blood-brain barrier (BBB) abnormalities. To explore the relationship between ectopic LEC properties and BBB disruption, we utilized endothelial cell-specific overexpression mutants.
