REVIEW
Silvio Erler, Oleg Lewkowski, Anja Poehlein, Eva Forsgren
Honeybees are prone to parasite and pathogen infestations/infections due to their social colony life. Bacterial pathogens in particular lead to destructive infections of the brood. European foulbrood is caused by the bacterium Melissococcus plutonius in combination with several other Gram-positive bacteria (Achromobacter eurydice, Bacillus pumilus, Brevibacillus laterosporus, Enterococcus faecalis, Paenibacillus alvei, Paenibacillus dendritiformis) involved as secondary invaders following the initial infection...

Humans sometimes perform actions which, at least superficially, appear suboptimal to the goal they are trying to achieve. Despite being able to identify these irrational actions from an early age, humans display a curious tendency to copy them. The current study recorded participants' movements during an established imitation task and manipulated the rationality of the observed action in two ways. Participants observed videos of a model point to a series of targets with either a low, high or 'superhigh' trajectory either in the presence or absence of obstacles between her targets...

REVIEW
Rahul Bhowmick, Ian D Hickson
An unusual feature of many eukaryotic genomes is the presence of regions that appear intrinsically difficult to copy during the process of DNA replication. Curiously, the location of these difficult-to-replicate regions is often conserved between species, implying a valuable role in some aspect of genome organization or maintenance. The most prominent class of these regions in mammalian cells is defined as chromosome fragile sites, which acquired their name because of a propensity to form visible gaps/breaks on otherwise-condensed chromosomes in mitosis...

Cyclic GMP-AMP synthetase (cGAS) is a DNA-specific cytosolic sensor, which detects and initiates host defense responses against microbial DNA. It is thus curious that a recent study identified cGAS as playing important roles in inhibiting positive-sense single-stranded RNA (+ssRNA) viral infection, especially since RNA is not known to activate cGAS. Using a dengue virus serotype 2 (DENV-2) vaccine strain (PDK53), we show that infection creates an endogenous source of cytosolic DNA in infected cells through the release of mitochondrial DNA (mtDNA) to drive the production of cGAMP by cGAS...

Musical obsessions also called "stuck song syndrome" is a topic of limited research. It is among the most poorly understood and rare phenomenology. There are only a few cases reported across the world which describes it. Subjects usually present with complaints of continuous play of a musical tune in the head which the subject is unable to remove. Because of its similarity in presentation with auditory musical hallucination, it presents a diagnostic dilemma to the clinician. Here, we present the case of a 25-year-old man who presented with this particular phenomenon, and the approach we took to manage it...

Vijith Kalathingal, Paul Dawson, J Mitra
The spectral distribution of light emitted from a scanning tunnelling microscope junction not only bears its intrinsic plasmonic signature but is also imprinted with the characteristics of optical frequency fluc- tuations of the tunnel current. Experimental spectra from gold-gold tunnel junctions are presented that show a strong bias (V b ) dependence, curiously with emission at energies higher than the quantum cut-off (eV b ); a component that decays monotonically with increasing bias. The spectral evolution is explained by developing a theoretical model for the power spectral density of tunnel current fluctuations, incorporating finite temperature contribution through consideration of the quantum transport in the system...

Although metaplasias have always attracted because of their strangeness, it is now clear they represent precursors for some of the most intractable human cancers. Despite this notoriety, they remain curiously understudied, and even their origins have been the subject of acrimonious debate stretching back to Virchow in the 19th century. Barrett's esophagus, with its high incidence, easy endoscopic access, and strong link to esophageal adenocarcinoma, would seem an ideal opportunity to address the origin problem...

Cysteine desulfurases, which supply sulfur for iron-sulfur cluster biogenesis, are broadly distributed in all phyla including cyanobacteria, the progenitors of plant chloroplasts. The SUF (sulfur utilization factor) system is responsible for Fe-S cluster biosynthesis under stress. The suf operon from cyanobacterium, Anabaena PCC 7120, showed the presence of a cysteine desulfurase, sufS ( alr2495 ) but not the accessory sulfur accepting protein (SufE). However, an ORF ( alr3513 ) encoding a SufE-like protein (termed as AsaE, Anabaena sulfur acceptor E) was found at a location distinct from the suf operon...

Protein modification by the small ubiquitin-like modifier (SUMO) plays important roles in genome maintenance. In Saccharomyces cerevisiae, proper regulation of sumoylation is known to be essential for viability in certain DNA repair mutants. Here we find the opposite result; proper regulation of sumoylation is lethal in certain DNA repair mutants. Yeast cells lacking the repair factors TDP1 and WSS1 are synthetically lethal due to their redundant roles in removing Top1-DNA covalent complexes (Top1ccs). A screen for suppressors of tdp1∆ wss1∆ synthetic lethality isolated mutations in genes known to control global sumoylation levels including ULP1, ULP2, SIZ2 and SLX5 The results suggest that alternative pathways of repair become available when sumoylation levels are altered...

Recent progress in forensic genetics has introduced a number of closely located short tandem repeat (STR) markers on the X chromosome. Inevitably, dependencies arise that have to be accounted for. This paper will in detail explore the complex statistical interpretation of X-chromosomal STR markers, focusing on likelihood calculations. Specifically, we will investigate how the phase uncertainty of haplotypes comes into play in the statistical evaluations and what curious effects this phenomenon can have. The starting point is the different real cases where the weight of evidence has provided unexpected results that require further investigation in order to be fully understood...

BACKGROUND: Pleomorphic fibroma is a curious neoplasm that exhibits striking cytologic atypia, yet behaves in benign fashion. The cytologic features including single cells with pleomorphic nuclei and scattered giant cells resemble the neoplastic cells of pleomorphic lipoma, a tumor with known retinoblastoma (Rb) loss. METHODS: We assessed the demographic and histopathologic features of a cohort of 26 pleomorphic fibromas, including assessment with immunostaining for Rb, p16, and Ki-67...

On the basis of tissue-specific enzyme activity and inhibition by catalytic products, Hans Krebs first demonstrated the existence of multiple glutaminases in mammals. Currently, two human genes are known to encode at least four glutaminase isoforms. However, the phylogeny of these medically relevant enzymes remains unclear, prompting us to investigate their origin and evolution. Using prokaryotic and eukaryotic glutaminase sequences, we built a phylogenetic tree whose topology suggested that the multidomain architecture was inherited from bacterial ancestors, probably simultaneously with the hosting of the proto-mitochondrion endosymbiont...

Nonsteroidal anti-inflammatory drugs are a common cause of intestinal injury. A variety of NSAID-induced injuries may occur including ulcers, erosions, colitis, strictures, and diaphragm disease. Diaphragm disease refers to the development of multiple thin, concentric, stenosing strictures in the intestine. Strictures occur most often in the midintestine and are thought to be pathognomonic of NSAID damage. They can lead to intermittent or complete bowel obstruction. Diagnosis may be elusive as there is nothing specific about NSAID-induced injury at endoscopy and histology is also nonspecific...

Chitosan oligosaccharides (COS) have been shown to regulate various cellular and biological functions. The aim of this study was to investigate the antimetastatic potency of COS and the underlying mechanism. Here, we established a stably N-acetylglucosaminyltransferase V (GnT-V)-overexpressed MCF10A cell line. As expected, GnT-V overexpression greatly promoted cell migration in the transfectants by using wound healing assay. However, the induction in the cell migration was significantly suppressed by an addition of COS...
