Does the use of face masks during the COVID-19 pandemic impact on oral hygiene habits, oral conditions, reasons to seek dental care and esthetic conc…
2021
Background To evaluate the impact of the use of face masks on oral hygiene habits; oral conditions self-perception; reasons to seek dental treatment; and esthetic concerns. Material and methods 1346 participants answered a web-based survey with questions related to the aims of the study. Descriptive statistic was performed and the responses were analyzed with chi-square test and regression analysis. Results With the use of masks, toothbrushing frequency decreased significantly, and people are significantly less concerned about oral hygiene. The number of subjects that reported to have halitosis increased significantly and this was associated with a decrease in toothbrushing frequency. The g…
A novel nutrient blend mimics calorie restriction transcriptomics differentially in multiple tissues of mice
2017
Identification of caloric restriction mimetics (CRMs), compounds that mimic the beneficial effects of caloric restriction (CR) without restriction of dietary energy would be an advancement in anti-aging science. The present study investigated whether the transcriptional profiles of a putative CRM nutrient blend could mimic that of CR in diverse tissues following long-term feeding in B6C3F1 male mice. Study design: Young Controls (YC; 5 mo.) and 3 groups treated from 14-30 mo.: Old Controls (OC), Old CR (OCR; 25% CR) and Old Supplemented (OS); n=7/group. Gene expression profiling in cerebral cortex (CCT), skeletal muscle (gastrocnemius)(SKL), heart (HRT), white adipose tissue (WAT) and liver…
Oxycodone extended release capsules for the treatment of chronic pain
2017
As a consequence of greater prescription opioid utilization, there has been the parallel increase in misuse, abuse, and overdose, which are serious risks. Associated new formulations may be safer. Areas covered: The introduction of abuse-deterrent opioid formulations and continuous programs to improve opioid prescribing practices may limit the opioid abuse and its consequences. Oxycodone extended release capsules are an extended-release (ER), microsphere-in-capsule abuse-deterrent-formulation designed to retain its extended-release properties following tampering or misuse (e.g., chewing, crushing). Studies have reported that this preparation is efficacious in patients with low back pain, le…
Expression of Wild-Type and Variant Estrogen Receptor Alpha in Liver Carcinogenesis and Tumor Progression.
2011
Although estrogen receptors (ERs) are expressed in human hepatocellular carcinoma (HCC), several clinical trials have failed to demonstrate the efficacy of antiestrogen treatment in HCC patients. Recently, the identification of several ER splicing variants has enlightened the complex nature of estrogen signaling in peripheral tissues; this may help understanding estrogen role in either nontumoral or malignant nonclassical target organs, including liver. In this work we have investigated mRNA expression of wild-type and splice variants of ERα in nontumoral, cirrhotic, and malignant human liver, as well as in HCC cell lines, using an exon-specific reverse transcription polymerase chain reacti…
ANCA-associated vasculitides: Recommendations of the French Vasculitis Study Group on the use of immunosuppressants and biotherapies for remission in…
2019
Treatment of vasculitides associated with anti-neutrophil cytoplasm antibodies (ANCA) (AAVs) has evolved dramatically in recent years, particularly since the demonstration of rituximab efficacy as remission induction and maintenance therapy for granulomatosis with polyangiitis and microscopic polyangiitis. In 2013, the French Vasculitis Study Group (FVSG) published recommendations for its use by clinicians. Since then, new data have made it possible to better specify and codify prescription of rituximab to treat AAVs. Herein, the FVSG Recommendations Committee, an expert panel comprised of physicians with extensive experience in the treatment and management of vasculitides, presents its con…
Physical activity responsive miRNAs – Potential mediators of training responses in human skeletal muscle?
2013
1. The basics of miRNA-mediated regulation The plasticity of skeletal muscle is of utmost importance for responding to and coping with environmental demands that emerge from changes in physical activity patterns, nourishment, hormonal status, and health. As is well known, a sedentary lifestyle, aging, immobilization, and chronic diseases are associated with reduced muscle mass and function, while regular exercise improves muscle function and reduces the rate of decrement throughout life. 1 However, we do not have a complete understanding of the molecular factors controlling skeletal muscle adaptation to exercise stimuli. Recently identified microRNA molecules (miRNAs) have rapidly gained at…
Medical significance of peroxisome proliferator-activated receptors.
1999
Peroxisome proliferator-activated receptors (PPAR) were discovered in 1990, ending 25 years of uncertainty about the molecular mechanisms of peroxisome proliferation. Subsequently, PPARs have improved our understanding of adipocyte differentiation. But there is more to PPARs than solving a puzzle about an organelle (the peroxisome) long considered an oddity, and their medical significance goes beyond obesity too. Enhanced PPAR type alpha expression protects against cardiovascular disorders though the role of enhanced PPARgamma expression seems less favourable. PPAR mechanisms, mainly via induction of more differentiated cell phenotypes, protect against some cancers. The differentiation of m…
BMP-2 and bFGF release and in vitro effect on human osteoblasts after adsorption to bone grafts and biomaterials.
2012
Objectives Combination of scaffolds and growth factors is a promising option for several clinical problems in bone biomaterials. Simplified growth factor loading by adsorption from aqueous solution is one important option for this technology. We evaluated the adsorption followed by PBS rinsing, release and biological effect of transient loading with basic fibroblast growth factor (bFGF) and bone morphogenic protein 2 (BMP-2) on fresh frozen bone, processed bone matrix, collagen, and a ceramic material with immunofluorescence, enzyme-linked immunosorbent assay (ELISA), and qRT-PCR. Materials and methods The study consisted of three in vitro experiments (immunofluorescence, ELISA, and qRT-PCR…
Primary paraesophageal Ewing’s sarcoma: an uncommon case report and literature review
2015
Ewing’s sarcoma is a rare and highly aggressive cancer most frequently arising in people under 20 years of age. We report an uncommon case of primary paraesophageal Ewing’s sarcoma in a 25-year-old male harboring the infrequent EWSR1/ERG fusion transcript with multiple splice variants coexisting in the same tumor. The patient was totally refractory to chemotherapy and died 17 months after diagnosis. We underscore the need for better understanding of the molecular pathogenesis of the disease and improved systemic therapy options.
NF-ĸB as node for signal amplification during weaning.
2011
Post-lactational involution has been reported to share common features with breast tumor development. A deep characterization of the signaling triggered after weaning would help to unveil the complex relationship between involution and breast cancer. NF-κB, a crucial factor in the involuting gland, might be an important regulatory node for signal amplification after weaning; however there is limited information about the identity of NF-κB-target genes and the molecular mechanisms leading to the selection of genes involved in a particular biological process. We identified 4532 target genes in mammary gland at 48h weaning, by genome-wide analysis of regions bound by RelA(p65)-NF-κB in vivo. I…
