The objective of this study was to evaluate the therapeutic efficacy and pharmacokinetic study of mucin1-aptamer functionalized miRNA-29b-loaded hybrid nanoparticles (MAFMILHN) in lung tumor-bearing SCID mice. MAFMILHN were manufactured using an iso-electric point based nanotechnology. They were then fully characterized for particle size, loading capacity, Zeta potential and encapsulation efficiency. The ability of MAFMILHN to downregulate oncoprotein DNMT3B both at the cellular level and in vivo was monitored using western blot, while the effect of the downregulation of DNMT3B on tumor growth was assessed using bioluminescence...

PURPOSE: This paper examines whether bilingual children with Specific Language Impairment (SLI) showed limited comprehension of Direct Object (DO) pronoun sentences and/or morphosyntactic priming compared to children with Typical Language Development (TLD) and adults. We analyzed the relation of these morphosyntactic processes to other psycholinguistic abilities, according to the MUC (Memory-Unification-Control) model. METHOD: Ten bilingual native Spanish-speaking children with SLI (8;3-10;6) and 10 age-matched children with TLD (7;6-10;10) received a psycholinguistic evaluation in Spanish-English...

In certain patients with advanced colorectal cancer, loss of phosphatase and tensin homolog deleted on chromosome 10 (PTEN) activity is observed. PTEN is a major gatekeeper gene of the AKT serine/threonine kinase (AKT) signaling pathway responsible for the proliferative activity of cells. The assessment of AKT activity may be a prognostic factor or a predictor of response to the targeted therapies against particular signaling proteins. To precisely identify the cause and the place of the pathway deregulation, it is necessary to identify phosphorylation states and concentrations of several proteins located at different levels of the regulatory cascade...

Idiopathic pulmonary fibrosis (IPF) is a chronic, debilitating, fibrotic lung disease leading to respiratory failure and ultimately to death. Being the prototype of interstitial lung diseases, IPF is characterized by marked heterogeneity regarding its clinical course. Despite significant progress in the understanding of its pathogenesis, we still cannot reliably predict the course of the disease and the response to treatment of an individual patient. Non-invasive biomarkers, in particular serum biomarkers, for the (early) diagnosis, differential diagnosis, prognosis and prediction of therapeutic response are urgently needed...

A microstructure-based model is developed to study the effective anisotropic properties (magnetic, dielectric or thermal) of two-phase particle-filled composites. The Green's function technique and the effective field method are used to theoretically derive the homogenized (averaged) properties for a representative volume element containing isolated inclusion and infinite, chain-structured particles. Those results are compared with the finite element approximations conducted for the assumed representative volume element...

Intestinal mucins trigger immune responses upon recognition by dendritic cells via protein-carbohydrate interactions. We used a combination of structural, biochemical, biophysical, and cell-based approaches to decipher the specificity of the interaction between mucin glycans and mammalian lectins expressed in the gut, including galectin (Gal)-3 and C-type lectin receptors. Gal-3 differentially recognized intestinal mucins with different O-glycosylation profiles, as determined by mass spectrometry (MS). Modification of mucin glycosylation, via chemical treatment leading to a loss of terminal glycans, promoted the interaction of Gal-3 to poly- N-acetyllactosamine...

Urothelial carcinoma of the bladder is a common malignancy which has historically been difficult to treat in its advanced stages. Clinically effective treatment options for locally advanced/inoperable or metastatic urothelial carcinoma (mUC) consisted of cisplatin-based chemotherapy regimens, with few other impactful therapeutic options. The past 2 years have seen a remarkable shift in the therapeutic landscape of mUC, with 5 novel immunotherapy agents receiving FDA approval for mUC, including first-line and second-line postplatinum settings...

INTRODUCTION: In the first- and second-line metastatic urothelial carcinoma (mUC) treatment setting, we investigated real-world outcomes and evaluated the prognostic role of neutrophil to lymphocyte ratio (NLR). METHODS: A retrospective analysis was performed on patients with mUC treated with systemic therapy. Overall response rates (ORRs), median time to treatment failure (mTTF), and median overall survival (mOS) were calculated. The association between baseline NLR (using a literature-derived cut-off of 3, as well as the best cut-off NLR value of 5...

A 74-year-oldwoman hadconsultedthe department of urology in our hospital because of microscopic hematuria. Cystoscopy revealeda urinary bladder tumor, suspectedas an adenocarcinoma basedon biopsy. MRI showeda cystic tumor of the appendix with vesical fistula; therefore, she underwent an operation with a diagnosis of appendiceal cancer invading the urinary bladder. During the operation, we found that the appendix sunk into the urinary bladder with right adnexa. Therefore, we performed ileocecal resection, partial resection of the urinary bladder, and right adnexectomy...

BACKGROUND: Kidney transplantation is the treatment of choice for patients with end-stage kidney disease. In a previous review we concluded that the routine use of ureteric stents in kidney transplantation reduces the incidence of major urological complications (MUC). Unfortunately, this reduction appears to lead to a concomitant rise in urinary tract infections (UTI). For kidney recipients UTI is now the commonest post-transplant complication. This represents a considerable risk to the immunosuppressed transplant recipient, particularly in the era of increased immunologically challenging transplants...

PURPOSE: Colon mucinous carcinomas (MUCs) have two morphological patterns: (i) glands lined by mucinous epithelium with direct contact to the stroma (FIX) and (ii) carcinoma cells floating in mucin (FLO). In this study, we evaluated the prognostic value of these patterns. METHODS: Digital images were captured from the 38 MUC's tissue sections. A grid with 140 points was laid over the computer screen. Totally, 100 points, falling on tumor cells floating in mucin (FLO patterned cells) or on cells contacting stroma (FIX patterned cells), were counted...

INTRODUCTION: Mucinous carcinoma is a variant of invasive breast carcinomas that accounts for 2% of them and has a better prognosis in contrast to the non-specific invasive carcinoma. They regularly are positive for estrogen and progesterone receptors and, generally, they do not overexpress HER2. When HER2 is positive, the first line treatment is trastuzumab; although the resistance is 52-89% for the non-specific carcinoma, it has been described just once in mucinous carcinoma. CASE SUMMARY: A 48-year-old female presented with a lump in her right breast and after a biopsy, it was diagnosed as mucinous carcinoma in the core biopsy and surgical resection, with positive hormone receptors and HER2 positive (3+) in 100% of the tumor cells...

The prognostic value of mucins expression in patients with head and neck cancer (HNC) remains controversial. To address this, a meta-analysis was performed to systematically evaluate prognostic significance of mucins expression in HNC. Electronic and manual searches were performed and a total of 20 studies including 2046 patients were selected for the final analysis. Increased mucins expression was associated with unfavorable overall survival in HNC patients (HR=1.83, 95% CI: 1.43-2.33, p=0.000). Mucins overexpression was also in correlation with more advanced TNM stage (RR=0...

Mucin 1 kidney disease, previously referred to as medullary cystic kidney disease type 1, is a rare hereditary kidney disease. It is one of several diseases now termed autosomal dominant tubulointerstitial kidney disease, as proposed by a KDIGO (Kidney Disease: Improving Global Outcomes) consensus report in 2014. Autosomal dominant tubulointerstitial kidney diseases share common clinical findings, such as autosomal dominant inheritance, bland urinary sediment, absent to mild proteinuria, and progressive loss of kidney function...

Endocrine disrupting chemicals (EDCs) from the environment are associated with reproductive abnormalities (i.e. decreased sperm concentration; increased endometriosis) and alterations of the cardiovascular system (i.e. increased blood pressure and risk of coronary disease). Some phthalates esters have been identified as EDCs, for which inhalation is considered as one of the routes of exposure. However, only little is known regarding inhalational exposure to EDCs via urban airborne particles. In the present study, we report the monthly concentration of 8 phthalate esters measured in PM10 and PM2...
