BACKGROUND: Radiation-induced osteosarcomas are a recognized complication of radiation therapy. Owing to the fact that it is rare, publications on radiation-induced osteosarcoma of the skull base are limited to a small series and some case reports. CASE PRESENTATION: We describe a rare case of a patient with a skull base radiation-induced osteosarcoma treated 11 years before with ionizing radiation for an undifferentiated carcinoma of the nasopharynx. The patient was treated with chemotherapy alone, but he died after the third cycle...

Bacterial pathogens such as methicillin-resistant Staphylococcus aureus (MRSA) represent a well-known public health problem affecting both healthcare-associated and community populations. Past studies have clearly shown the value of characterizing problem organisms including MRSA through the use of molecular techniques (i.e., strain typing), with the aim of informing local, regional, and national efforts in epidemiological analysis and infection control. The country of Libya represents a challenge for such analysis due to limited historical infectious disease information and major political unrest culminating in the Libyan Civil War (Libyan Revolution) in 2011...

We hypothesized that genistein could affect the chloride (Cl(-) ) and bicarbonate (HCO3(-) ) secretory mechanisms in uterus. Ovariectomized female rats were given estradiol or estradiol plus progesterone with 25, 50, or 100 mg/kg/day genistein. Following completion of the treatment, uterine fluid Cl(-) and HCO3(-) concentrations were determined by in vivo uterine perfusion. Uteri were subjected for molecular biological analysis (Western blot, qPCR, and immunohistochemistry) to detect levels of expression of Cystic Fibrosis transmembrane regulator (CFTR), Cl(-) /HCO3(-) exchanger (SLC26a6), Na(+) /HCO3(-) cotransporter (SLC4a4), and estrogen receptor (ER)-α and β...

The adolescent period in mammals is a critical period of brain maturation and thus represents a time of susceptibility to environmental insult, e.g. psychosocial stress and/or drugs of abuse, which may cause lasting impairments in brain function and behavior and even precipitate symptoms in at-risk individuals. One likely effect of these environmental insults is to increase oxidative stress in the developing adolescent brain. Indeed, there is increasing evidence that redox dysregulation plays an important role in the development of schizophrenia and other neuropsychiatric disorders and that GABA interneurons are particularly susceptible to alterations in oxidative stress...

New biosourced chiral cross-linkers were reported for the first time in the synthesis of methyltestosterone (MT) chiral molecularly imprinted polymers (cMIPs). Isosorbide and isomannide, known as 1,4:3,6-dianhydrohexitols, were selected as starting diols. The cMIPs were synthesized following a noncovalent approach via thermal radical polymerization and monitored by Raman spectroscopy. These cross-linkers were fully characterized by (1) H and (13) C nuclear magnetic resonance (NMR) spectroscopy and high-resolution mass spectrometry...

BACKGROUND: The penicillin therapy of β hemolytic streptococcal pharyngitis has aided in the decrease of rheumatic heart disease (RHD) in developing countries. Tunisia is an endemic area, however, and incidence of RHD is weakly documented. We aimed at establishing the standardized incidence rate (SIR) of RHD in Monastir governorate and at determining RHD prevalence among hospitalized patients in two cardiology departments. METHODS: From the regional register of Monastir Hospital morbidity, we have selected newly diagnosed patients with RHD, residents of Monastir, and hospitalized to the 2 cardiology departments between 2000 and 2013 (2001 not included)...

The bacterial community structure and diversity were assessed at the scale of rotating biodisk procedure (RB) in a semi-industrial pilot plant. As well, the Salmonella community was particularly monitored, and the effects of ultraviolet (UV-C254) on the bacterial community were studied. The identification of dominant bacteria revealed the presence of beneficial and useful species that could play an important role in the process of wastewater purification. Several species as Enterobacter agglomerans, Cronobacter sakazakii, and Pantoea agglomerans known for their bioremediation activities were revealed in the majority of biofilm samples...

BACKGROUND: Random forests are successful classifier ensemble methods consisting of typically 100 to 1000 classification trees. Ensemble pruning techniques reduce the computational cost, especially the memory demand, of random forests by reducing the number of trees without relevant loss of performance or even with increased performance of the sub-ensemble. The application to the problem of an early detection of glaucoma, a severe eye disease with low prevalence, based on topographical measurements of the eye background faces specific challenges...

Microfluidic systems based on polydimethylsiloxane (PDMS) provide a versatile platform to study the mechanoresponse of cells in vitro. Under a shear flow, however, the stability of cells that were grown on physically adsorbed proteins is short lived, which limits long-term cell studies. To address this issue, we used (3-Aminopropyl)triethoxysilane (APTES) as a linker between PDMS and collagen. In micro-channels that were modified with APTES-anchored collagen, fibroblast cells demonstrated higher stability and better proliferation as compared to collagen that was physically adsorbed onto PDMS after oxygen plasma treatment...

REVIEW
Asma Yaghi, Myrna B Dolovich
Airway epithelium is the first line of defense against exposure of the airway and lung to various inflammatory stimuli. Ciliary beating of airway epithelial cells constitutes an important part of the mucociliary transport apparatus. To be effective in transporting secretions out of the lung, the mucociliary transport apparatus must exhibit a cohesive beating of all ciliated epithelial cells that line the upper and lower respiratory tract. Cilia function can be modulated by exposures to endogenous and exogenous factors and by the viscosity of the mucus lining the epithelium...

Objective: To determine whether COPD severity correlates with sputum cell counts, atopy, and asthma. Methods: This was a cross-sectional study involving 37 patients with COPD and 22 healthy subjects with normal lung function (controls). Sputum cell counts were determined by microscopy after centrifugation of samples. Skin prick tests were performed, and serum cytokines were determined by ELISA. Results: Patients were stratified by bronchodilator response: a non-reversible airflow limitation (nonRAL) group comprised 24 patients showing no significant post-bronchodilator change in FEV1; and a partially reversible airflow limitation (partialRAL) group comprised 13 patients showing FEV1 reversibility (post-bronchodilator FEV1 increase ≥ 12%)...

: Diagnostic radiographic imaging scans using intravascular iodinated contrast media can lead to various complications. The most salient of these is contrast-induced acute kidney injury (CI-AKI) or contrast-induced nephropathy, a potentially costly and serious patient safety concern. Prevention strategies are the cornerstone of evidence-based clinical management for patients receiving contrast agents. These include preprocedure screening, stratification of patients based on risk factors, and protective interventions, the most important of which is hydration both before and after the radiographic imaging scan...
