Honey is a complex mixture of various substances, and its composition depends on both botanical and geographical origin, as well as anthropogenic factors. The accurate identification of honey origin guarantees the satisfaction of consumers' needs and has an impact on the honey market value. Physicochemical parameters, some of which are used in routine analysis of honey quality, could be useful for the assessment of its origin. In this review, special attention is paid to those studies that assessed the sugar and mineral composition of honey, whether they were investigated in terms of botanical or geographical origin, or for the characterization of honey type...

Acute subdural hematoma caused by cerebral aneurysm rupture is rare. We describe a clinical case of an acute subdural hematoma developed due to rupture of an aneurysm at the M1 segment bifurcation of the middle cerebral artery (MCA). The acute subdural hematoma associated with intracranial hypertension and transtentorial herniation resulted in a comatose condition. The patient underwent decompressive craniectomy, hematoma removal, and clipping of the aneurysm. A significant improvement was observed in the postoperative period...

Imipenem is active against extended-spectrum β-lactamase-producing Enterobacteriaceae (ESBL-E) but favours the intestinal emergence of resistance. The effects of imipenem on intestinal microbiota have been studied using culture-based techniques. In this study, the effects were investigated in patients using culture and metagenomic techniques. Seventeen hospitalised adults receiving imipenem were included in a multicentre study (NCT01703299, http://www.clinicaltrials.gov). Most patients had a history of antibiotic use and/or hospitalisation...

In Croatia, the majority of the common bean production is based on local landraces, grown by small-scale farmers in low input production systems. Landraces are adapted to the specific growing conditions and agro-environments and show a great morphological diversity. These local landraces are in danger of genetic erosion caused by complex socio-economic changes in rural communities. The low profitability of farms and their small size, the advanced age of farmers and the replacement of traditional landraces with modern bean cultivars and/or other more profitable crops have been identified as the major factors affecting genetic erosion...

Huntington's disease (HD) has been recently shown to have a horizontally transmitted, prion-like pathology. Thus, the migration of polyglutamine-containing aggregates to acceptor cells is important for the progression of HD. These aggregates contain glyceraldehyde-3-phosphate dehydrogenase (GAPDH), which increases their intracellular transport and their toxicity. Here, we show that RX624, a derivative of hydrocortisone that binds to GAPDH, prevents the formation of aggregates of GAPDH-polyglutamine excreted into the culture medium by PC-12 rat cells expressing mutant huntingtin...

Metallodrugs offer potential for unique mechanism of drug action based on the choice of the metal, its oxidation state, the types and number of coordinated ligands and the coordination geometry. This review illustrates notable recent progress in the field of medicinal bioinorganic chemistry as many new approaches to the design of innovative metal-based anticancer drugs are emerging. Current research addressing the problems associated with platinum drugs has focused on other metal-based therapeutics that have different modes of action and on prodrug and targeting strategies in an effort to diminish the side-effects of cisplatin chemotherapy...

Uromodulin is the most abundant urinary protein in physiological conditions. It is exclusively produced by renal epithelial cells lining the thick ascending limb of Henle's loop (TAL) and it plays key roles in kidney function and disease. Mutations in UMOD, the gene encoding uromodulin, cause autosomal dominant tubulointerstitial kidney disease uromodulin-related (ADTKD-UMOD), characterised by hyperuricemia, gout and progressive loss of renal function. While the primary effect of UMOD mutations, retention in the endoplasmic reticulum (ER), is well established, its downstream effects are still largely unknown...

In ERP studies of cognitive processes during attentional tasks, the cue signals containing information about the target can increase the amplitude of the parietal cue P3 in relation to the 'neutral' temporal cue, and reduce the subsequent target P3 when this information is valid, i.e. corresponds to the target's attributes. The present study compared the cue-to-target P3 ratios in neutral and visuospatial cueing, in order to estimate the contribution of valid visuospatial information from the cue to target stages of the task performance, in terms of cognitive load...

PURPOSE: Trans-oral robotic surgery (TORS) followed by adjuvant radiation therapy (RT) is becoming popular in treating node-positive tonsillar squamous cell carcinoma (SCC). One potential benefit is eliminating irradiation of the primary site when the tumor is widely resected, and targeting the neck only. This study assessed whether omitting the tumor bed provides any dosimetric or clinical advantage. METHODS AND MATERIALS: We identified 21 patients with primary tonsillar SCC that were treated with TORS followed by RT to the ipsilateral neck and primary (N+P) site...

The future of solid-state lighting can be potentially driven by applications of InGaN/GaN core-shell nanowires. These heterostructures provide the possibility for fine-tuning of functional properties by controlling a strain state between mismatched layers. We present a nondestructive study of a single 400 nm-thick InGaN/GaN core-shell nanowire using two-dimensional (2D) X-ray Bragg ptychography (XBP) with a nanofocused X-ray beam. The XBP reconstruction enabled the determination of a detailed three-dimensional (3D) distribution of the strain in the particular nanowire using a model based on finite element method...

In both prokaryotes and eukaryotes, the survival at temperatures considerably exceeding the optimum is supported by intense synthesis of the so-called heat shock proteins (HSPs), which act to overcome the adverse effects of heat stress. Among mycoplasmas (class Mollicutes), which have significantly reduced genomes, only some members of the Acholeplasmataceae family possess small HSPs of the α-crystallin type. Overproduction of a recombinant HSP IbpA (Hsp20) from the free-living mycoplasma Acholeplasma laidlawii was shown to increase the resistance of Escherichia coli to short-term heat shock...

Context • Pleasant music that evokes a positive emotional response may activate brain pathways of the insular cortex, central nucleus of the amygdala, and lateral hypothalamus, which are involved in the integration of emotional and ambient sensory input, with corresponding autonomic responses. Exercise training can improve endothelium-dependent vasodilatation, both in epicardial coronary vessels and in resistance vessels, for patients with coronary heart disease. Objective • The aim of the present study was to evaluate the effects on endothelial function when patients with stable coronary artery disease (CAD) listened to their favorite music...
