Emotion enhances episodic memory, an effect thought to be an adaptation to prioritise the memories that best serve evolutionary fitness. But viewing this effect largely in terms of prioritising what to encode or consolidate neglects broader rational considerations about what sorts of associations should be formed at encoding, and which should be retrieved later. Although neurobiological investi...

Prior work on organization in free recall has focused on the ways in which semantic and temporal information determine the order in which material is retrieved from memory. Tulving’s theory of ecphory suggests that these organizational effects arise during the recall process, through the interaction of a retrieval cue with the contents of memory. Using the continual-distraction free-recall para...

Reticulocytes release small membrane vesicles termed exosomes during their maturation into erythrocytes. Exosomes are intraluminal vesicles of multivesicular endosomes released into the extracellular medium by fusion of these endosomal compartments with the plasma membrane. This secretion pathway contributes to reticulocyte plasma membrane remodeling by eliminating certain membrane glycoprotein...

We continue the study of k-monotone Boolean functions in the property testing model, initiated by Canonne et al. (ITCS 2017). A function f : {0, 1} → {0, 1} is said to be kmonotone if it alternates between 0 and 1 at most k times on every ascending chain. Such functions represent a natural generalization of (1-)monotone functions, and have been recently studied in circuit complexity, PAC learni...

In studies of the inhibition in viva of animal viruses by poly-n-lysine, Rubini et al. (1) and Green et al. (2-4) obtained data which suggested that poly-L-lysine is hydrolyzed by the proteolytic enzymes of the allantoic fluid, and that this enzymatic hydrolysis may limit its biological activity. The enzymatic hydrolysis of poly-n-lysine was reported by Katchalski (5) and by Waley and Watson (6...

Uracil-Specific Exision Reagent (USER) fusion is a recently developed technique that allows for assembly of multiple DNA fragments in a few simple steps. However, designing primers for USER fusion is both tedious and time consuming. Here, we present the Primer Help for USER (PHUSER) software, a novel tool for designing primers specifically for USER fusion and USER cloning applications. We also ...

A significant body of evidence shows that polyglutamine (polyQ) tracts are important for various biological functions. The characteristic polymorphism of polyQ length is thought to play an important role in the adaptation of organisms to their environment. However, proteins with expanded polyQ are prone to form amyloids, which cause diseases in humans and animals and toxicity in yeast. Saccharo...

Stimulus-responsive nanogels have potential as carriers for drugs targeting the skin. It is important to estimate the biocompatibility of such materials with the skin since they are directly in contact upon application and may induce irritation or inflammation. In the current work, blank (drug-free) polyN-isopropylacrylamide (polyNIPAM), poly(NIPAM copolymerized butyl acrylate) [poly(NIPAM-co-B...

The icaADBC gene was first identified in Staphylococcus epidermidis, and is also present in Staphylococcus aureus and other Staphylococcal species. PIA is produced by the gene products encoded by the icaADBC operon. Asymptomatically colonized patients and health care workers are the major sources of MRSA in the hospital environment. MRSA-infected patients in burns units are particularly problem...
