Routine forensic analysis using STRs will fail if the DNA is too degraded. The DNA degradation process in biological stain material is not well understood. In this study we sequenced old semen and blood stains by massively parallel sequencing. The sequence data coverage was used to measure degradation across the genome. The results supported the contention that degradation is uniform across the genome, showing no evidence of regions with increased or decreased resistance towards degradation. Thus the lack of genetic regions robust to degradation removes the possibility of using such regions to further optimize analysis performance for degraded DNA...

Nucleotide-binding domain and leucine-rich repeat proteins (NLRs) are important receptors in plant immunity that allow recognition of pathogen effectors. The rice NLR RGA5 recognizes the Magnaporthe oryzae effector AVR-Pia through direct interaction. Here, we gained detailed insights into the molecular and structural bases of AVR-Pia-RGA5 interaction and the role of the RATX1 decoy domain of RGA5. NMR titration combined with in vitro and in vivo protein-protein interaction analyses identified the AVR-Pia interaction surface that binds to the RATX1 domain...

: The circadian system may regulate adult neurogenesis via intracellular molecular clock mechanisms or by modifying the environment of neurogenic niches, with daily variation in growth factors or nutrients depending on the animal's diurnal or nocturnal life-style. In a diurnal vertebrate, zebrafish, we studied circadian distribution of immunohistochemical markers of the cell division cycle (CDC) in five of the sixteen neurogenic niches of adult brain, the dorsal telencephalon, habenula, preoptic area, hypothalamus and cerebellum...

Activating mutations in the phosphoinositide 3-kinase (PI3K) signaling pathway are frequently identified in cancer. To identify pathways that support PI3K oncogenesis, we performed a genome-wide RNAi screen in isogenic cell lines harboring wild-type or mutant PIK3CA to search for PI3K synthetic-lethal (SL) genes. A combined analysis of these results with a meta-analysis of two other large-scale RNAi screening data sets in PI3K mutant cancer cell lines converged on ribosomal protein translation and proteasomal protein degradation as critical nononcogene dependencies for PI3K-driven tumors...

An intrinsic timing mechanism specifies the positional values of the zeugopod (i.e. radius/ulna) and then autopod (i.e. wrist/digits) segments during limb development. Here we have addressed if this timing mechanism ensures that patterning events occur only once by grafting GFP-expressing autopod progenitor cells to the earlier host signaling environment of zeugopod progenitor cells. We show that early and late autopod progenitors fated for the wrist and phalanges, respectively, both contribute to the entire host autopod indicating that the autopod positional value is irreversibly determined as revealed by Hoxa13 expression...

Diverse neurodegenerative disorders are characterized by deposition of tau fibrils composed of conformers (i.e. strains) unique to each illness. The development of tau imaging agents has enabled visualization of tau lesions in tauopathy patients, but the modes of their binding to different tau strains remain elusive. Here we compared binding of tau positron emission tomography ligands, PBB3 and AV-1451, by fluorescence, autoradiography and homogenate binding assays with homologous and heterologous blockades using tauopathy brain samples...

BACKGROUND: Left ventricular ejection fraction remains the primary risk stratification tool used in the selection of patients for implantable cardioverter defibrillator therapy. However, this solitary marker fails to identify a substantial portion of patients experiencing sudden cardiac arrest. In this study, we examined the incremental value of considering right ventricular ejection fraction for the prediction of future arrhythmic events in patients with systolic dysfunction using the gold standard of cardiovascular magnetic resonance...

: Among the bacteria, members of the Actinomycetales are considered quintessential degraders of complex polysaccharides in soils. However, studies examining complex polysaccharide degradation by Actinomycetales (other than Streptomyces spp.) in soils are limited. Here, we examine the lignocellulolytic and chitinolytic potential of 112 Actinomycetales strains, encompassing 13 families, isolated from a semi-arid grassland of the Colorado Plateau, Utah, USA. Members of the Streptomycetaceae, Pseudonocardiaceae, Micromonosporaceae and Promicromonosporaceae exhibited robust activity against carboxymethylcellulose, xylan, chitin and pectin substrates (except for low/no pectinase activity by the Micromonosporaceae)...

Based on similarities between overconsumption of food and addictive drugs, there is increasing interest in "food addiction," a compulsive eating pattern defined using symptoms parallel to substance use disorders. Impulsivity, a multidimensional construct robustly linked to drug addiction, has been increasingly examined as an obesity determinant, but with mixed findings. This study sought to clarify relations between three major domains of impulsivity (i.e., impulsive personality traits, discounting of delayed rewards, and behavioral inhibition) in both obesity and food addiction...

It is often challenging to precisely manipulate the release behavior of hydrophilic drugs that is believed to be crucial for a satisfactory therapeutic outcome. The aim of this work was to regulate the dissolution of hydrophilic drug from hot-melt extruded solid dispersion via rational screening of the pore-forming agents. Venlafaxine hydrochloride and Compritol® 888 ATO was selected as the model drug and carrier excipient, respectively. Hydrophilic polyethylene glycol (PEG 6000) and polyvinylpyrolidone (PVP K30) were chosen as the transient pore-forming agents...

Phosgene Oxime (CX), an urticant or nettle agent categorized as a vesicant, is a potential chemical warfare and terrorist weapon. Its exposure can result in widespread and devastating effects including high mortality due to its fast penetration and ability to cause immediate severe cutaneous injury. It is one of the least studied chemical warfare agents with no effective therapy available. Thus, our goal was to examine the acute effects of CX following its cutaneous exposure in SKH-1 hairless mice to help establish a relevant injury model...

Inclusion body hepatitis (IBH) is one of the major viral infections causing substantial economic loss to the global poultry industry. The disease is characterized by a sudden onset of mortality (2-30%) and high morbidity (60-70%). IBH is caused by a number of serotypes of fowl adenovirus with substantially low levels of serotype cross protection. Thus far, there is no effective and safe vaccine commercially available in the North America for the control of IBH in chickens. Poly[di(sodium carboxylatoethylphenoxy)]phosphazene (PCEP) is a high molecular weight, biodegradable water soluble polymer that has been well characterized as a safe and effective adjuvant for a number of experimental veterinary vaccines...

Although useful prognostic and predictive insights can be gained from patient and tumour characteristics in early-stage breast cancer, it is not always straightforward to predict the likely risk of recurrence for each individual patient following breast surgery. One of the most difficult challenges faced by clinicians is identifying patients who may benefit most from adjuvant chemotherapy, and distinguishing these cases from those where endocrine therapy may be sufficient for cure. Genomic tests such as the Oncotype DX(®) Breast Recurrence Score(®) Assay have been developed to provide a robust and clinically validated assessment of a patient's individual tumour signature...

This paper investigates the problem of robust observer-based passive control for uncertain singular time-delay system subject to actuator saturation. A polytopic approach is used to describe the saturation behavior. First, by constructing Lyapunov-Krasovskii functional, a less conservative sufficient condition is obtained which guarantees that the closed-loop system is regular, impulse free, stable and robust strictly passive. Then, with this condition, the design method of state feedback controller and the observer are given by solving linear matrix inequalities...

BACKGROUND: To improve the accuracy of ultrasound-guided biopsy of the prostate, the non-rigid registration of magnetic resonance (MR) images onto transrectal ultrasound (TRUS) images has gained increasing attention. Mutual information (MI) is a widely used similarity criterion in MR-TRUS image registration. However, the use of MI has been challenged because of intensity distortion, noise and down-sampling. Hence, we need to improve the MI measure to get better registration effect. METHODS: We present a novel two-dimensional non-rigid MR-TRUS registration algorithm that uses correlation ratio-based mutual information (CRMI) as the similarity criterion...
