CONCLUSION: The sensitivity and specificity of a (18)FDG-PET scan may be different according to the histology. The SUVmax and SUV ratio may reflect the tumor's aggressive behavior. OBJECTIVES: To describe the characteristics of PET/CT scans, including the maximum standard uptake values (SUVmax), at initial diagnosis according to six main types of sinonasal malignancies: sinonasal adenocarcinoma (SNAC), sinonasal undifferentiated carcinoma (SNUC), adenoid cystic carcinoma (ACC), sinonasal malignant melanoma (SMM), olfactory neuroblastoma (ONB), and sinonasal neuroendocrine carcinoma (SNEC)...

BACKGROUND: We aimed to quantify the independent effect of cognitive and physical deficits on the risk of injurious falls, to verify whether this risk is modified by global cognitive impairment, and to explore whether risk varies by follow-up time. METHODS: Data on 2,495 participants (≥60 years) from the population-based Swedish National Study on Aging and Care in Kungsholmen (SNAC-K) study were analyzed using flexible parametric survival models. Two cognitive domains (processing speed and executive function) were assessed with standard tests...

Insects under different stimuli from the environment modify behavioural responses due to changes in the sensitivity of neurons at the peripheral and/or at the central level of the nervous system. This phenomenon is called neuronal plasticity, and sensory adaptation is an example of it. An insect repellent is a chemical that produces oriented movements of the insects away from its source. In this work we studied the modulation of the behavioural and electrical response to the repellent N, N-diethyl-3-methylbenzamide (DEET) in males of the German cockroach B...

Intestinal permeation enhancers (PEs) are key components in ∼12 oral peptide formulations in clinical trials for a range of molecules, primarily insulin and glucagon-like-peptide 1 (GLP-1) analogs. The main PEs comprise medium chain fatty acid-based systems (sodium caprate, sodium caprylate, and N-[8-(2-hydroxybenzoyl) amino] caprylate (SNAC)), bile salts, acyl carnitines, and EDTA. Their mechanism of action is complex with subtle differences between the different molecules. With the exception of SNAC and EDTA, most PEs fluidize the plasma membrane causing plasma membrane perturbation, as well as enzymatic and intracellular mediator changes that lead to alteration of intestinal epithelial tight junction protein expression...

INTRODUCTION: Chromosomal translocations at 2p23 cause overexpression of anaplastic lymphoma kinase (ALK), a receptor tyrosine kinase involved in signalling pathways that regulate cell proliferation. This translocation occurs in 5% of lung adenocarcinoma and has been demonstrated to be useful as a therapeutic target for crizotinib. sinonasal adenocarcinomas (SNAC) are histologically similar to lung adenocarcinomas; the aim of this study was to evaluate the presence of ALK alterations in SNAC...

Perilunate fracture-dislocations usually combine ligament ruptures, bone avulsions, and fractures in different patterns. Rarely a displaced fracture of the scaphoid can coexist with a scapho-lunate dissociation and can result in enucleation of the proximal pole. We report about a case of trans-scaphoid perilunate dislocation with palmar extrusion/enucleation of the scaphoid proximal pole, treated with scaphoid fracture open reduction and internal fixation with screw, scapho-lunate ligament repair with an anchor and vascularization of the scaphoid proximal pole with the 2nd intermetacarpal artery...

Spirolaxine is a natural product isolated from Sporotrichum laxum ATCC 15155, which has shown a variety of biological activities including promising anti-Helicobacter pylori property. To understand how this compound is biosynthesized, the genome of S. laxum was sequenced. Analysis of the genome sequence revealed two putative type III polyketide synthase (PKS) genes in this strain, Sl-pks1 and Sl-pks2, which are located adjacent to each other (~2.0 kb apart) in a tail-to-tail arrangement. Disruption of these two genes revealed that Sl-PKS2 is the dedicated PKS involved in the biosynthesis of spirolaxine...

Volatile fatty acids (VFA), inorganic carbon (IC) and total ammonia nitrogen (TAN) are key variables in the current context of anaerobic digestion (AD). Accurate measurements like gas chromatography and infrared spectrometry have been developed to follow the concentration of these compounds but none of these methods are affordable for small AD units. Only titration methods answer the need for small plant monitoring. The existing methods accuracy was assessed in this study and reveals a lack of accuracy and robustness to control AD plants...

BACKGROUND: We aimed to investigate the impact of dementia on drug costs in older people, after adjustment for socio-demographic factors, residential setting and co-morbidities. METHODS: We included 4,129 individuals aged ≥ 60 years from The Swedish National Study on Aging and Care (SNAC) in Kungsholmen and Nordanstig 2001-2004. A generalized linear model (GLM) was used to investigate how much dementia was associated with drug costs. RESULTS: Overall drug costs for persons with and without dementia were 6147 SEK (816 USD) and 3810 SEK (506 USD), respectively...

The primary S-nitrosothiol, S-nitroso-N-acetylcysteine (SNAC) is a nitric oxide donor with potential pharmaceutical applications for the oral treatment of hepatic steatosis and cirrhosis and for protection against gastric acid-peptic disorders. However, its low thermal stability precludes the preparation of stable dosage forms based on presynthesized SNAC. In this study, we describe an innovative strategy for the oral administration of SNAC based on its intratablet formation via the S-nitrosation reaction of its parent stable thiol, N-acetyl-L-cysteine by nitrous acid during the absorption of water by the tablet...

NAC proteins comprise a large family of transcription factors that play important roles in diverse physiological processes during development. To explore the role of NAC transcription factors in the ripening of fruits, we predicted the secondary and tertiary structure as well as regulative function of the SNAC4 (SlNAC48, Accession number: NM 001279348.2) and SNAC9 (SlNAC19, Accession number: XM 004236996.2) transcription factors in tomato. We found that the tertiary structure of SNAC9 was similar to that of ATNAP, which played an important role in the fruit senescence and was required for ethylene stimulation...

BACKGROUND AND OBJECTIVE: Carpal fusions are useful for treating specific carpal disorders, maximizing postoperative wrist motion, hand strength, reducing pain and instability of the joint. The surgeon selects the appropriate treatment by considering the degree of stability, the chronicity of the injury, functional demands of the patient and former patient's outcomes as well. However there are not many studies regarding the load distribution provided by the treatment. So, the purpose of this study is to analyze the load distribution through the wrist joint with an arthrodesis treatment and compare the results with a normal wrist...

Expression levels of the NAC gene family were studied in rice infected with Rice dwarf virus (RDV), Rice black-streaked dwarf virus (RBSDV), Rice grassy stunt virus (RGSV), Rice ragged stunt virus (RRSV), and Rice transitory yellowing virus (RTYV). Microarray analysis showed that 75 (68%) OsNAC genes were differentially regulated during infection with RDV, RBSDV, RGSV, and RRSV compared with the control. The number of OsNAC genes up-regulated was highest during RGSV infection, while the lowest number was found during RTYV infection...

BACKGROUND: Reduced white matter integrity, as indicated by lower fractional anisotropy (FA) and higher mean diffusivity (MD), has been related to poorer perceptual speed (PS) performance. As the ε4 allele has been associated with lower white matter integrity in old age, this represents a potential mechanism through which APOE may affect PS. OBJECTIVE: To examine whether the association between APOE and PS is mediated by white matter microstructure in very old persons without dementia...
