The awesome technological marvels of laser-guided munitions and rocketry riveted everyone's attention during the recent Persian Gulf War. Yet, an aspect of the war that received comparatively little media attention was the constant battle waged against potential disease vectors by preventive medicine personnel from the coalition forces. The extraordinarily small number of casualties suffered in...

In bone marrow, the differentiation of osteoblasts and adipocytes is reciprocally regulated. This inverse regulation occurs mainly through complex signaling crosstalk between transcriptional factors such as peroxisome proliferator-activated receptor-γ (PPARγ) and runt-related transcription factor 2 (Runx2). This commentary addresses the role of myeloid elf-1 like factor (MEF) and distal-less ho...

While adipose-derived stem cell-conditioned medium (ADSC-CM) has been demonstrated to promote skin wound healing, the mechanism regulating this effect remains unelucidated. In this study, we aimed to investigate the role of Ell3 in the wound healing activity of ADSC-CM. In vitro analysis revealed that Ell3 suppression in ADSCs impairs the promotive activity of ADSC-CM on the proliferation and m...

In metal-enhanced fluorescence (MEF), the localized surface plasmon resonances of metallic nanostructures amplify the absorption of excitation light and assist in radiating the consequent fluorescence of nearby molecules to the far-field. This effect is at the base of various technologies that have strong impact on fields such as optics, medical diagnostics, and biotechnology. Among possible em...

The myogenin gene, a member of the gene family encoding muscle-specific basic-helix-loop-helix transcription factors, is activated in myoblasts at the onset of differentiation and can be induced in fibroblasts by forced expression of MyoD or its relatives. Here, we report that a small proximal promoter region of the Myf-4 gene, the human myogenin homolog, suffices to direct muscle-specific expr...

The Epidemiology of otitis media with spontaneous perforation of the tympanic membrane and associated nasopharyngeal carriage of bacterial otopathogens was analysed in a county in Catalonia (Spain) with pneumococcal conjugate vaccines (PCVs) not included in the immunization programme at study time. A prospective, multicentre study was performed in 10 primary care centres and 2 hospitals (June 2...

MicroRNAs (miRNAs) are short 20-22 nucleotide RNA molecules that act as negative regulators of gene expression via translational repression: they have been shown to play a role in development, proliferation, stress response, and apoptosis. The transcriptional regulator LRF (Leukemia/lymphoma Related Factor) has been shown to prevent p19ARF transcription and consequently to inhibit senescence in...

The purpose of the study was to identify the relationships between segmental angular momentum and ball velocity between the following events: ball toss, maximal elbow flexion (MEF), racket lowest point (RLP), maximal shoulder external rotation (MER), and ball impact (BI). Ten tennis players performed serves recorded with a real-time motion capture. Mean angular momentums of the trunk, upper arm...

In streptococci mef(I) and catQ, two relatively uncommon macrolide and chloramphenicol resistance genes, respectively, are typically linked in a genetic module designated IQ module. Though variable, the module consistently encompasses, and is sometimes reduced to, a conserved ∼5.8-kb mef(I)-catQ fragment. The prototype IQ module was described in Streptococcus pneumoniae. IQ-like modules have su...

PURPOSE Chronic otitis media with effusion (OME) is the leading cause of hearing loss during childhood. In bacterial etiology of OME, the most frequent pathogens responsible are Haemophilus influenzae followed by Streptococcus pneumoniae and Moraxella catarrhalis. This study aimed at evaluating the accuracy of nasopharyngeal (NP) specimens in the identification of pathogens in the middle ear fl...
