Studies show that radiotherapy of a primary tumor in combination with immunoadjuvants (IA) can result in increased survival or immune-mediated regression of metastasis outside the radiation field, a phenomenon known as abscopal effect. However, toxicities due to repeated systematic administration of IA have been shown to be a major obstacle in clinical trials. To minimize the toxicities and prime a more potent immune response, Ngwa et al have proposed that inert radiotherapy biomaterials such as fiducials could be upgraded to multifunctional ones loaded with IA for in situ delivery directly into the tumor sub-volume at no additional inconvenience to patients...

Considering that the prevalence of antibiotic-resistant pathogenic bacteria is largely increasing, a thorough understanding of penicillin-binding proteins (PBPs) is of great importance and crucial significance because this enzyme family is a main target of β-lactam-based antibiotics. In this work, combining biochemical and structural analysis, we present new findings that provide novel insights into PBPs. Here, a novel PBP homologue (CcEstA) from Caulobacter crescentus CB15 was characterized using native-PAGE, mass spectrometry, gel filtration, CD spectroscopy, fluorescence, reaction kinetics, and enzyme assays toward various substrates including nitrocefin...

A Gram-positive, non-spore forming actinobacterium strain 9H-4T isolated from the choana of a garden warbler (Sylvia borin) was studied to examine its taxonomic position. On the basis of the 16S rRNA gene sequence analysis it was shown that strain 9H-4T belongs to the genus Aeromicrobium with Aeromicrobium flavum (98.7 %) and Aeromicrobium tamlense (98.4 %) as the nearest neighbours and forms a separate branch in a neighbour-joining 16S rRNA gene sequence based phylogenetic tree. DNA-DNA hybridizations confirmed its novel species identity by 39 % and 46 % DNA-DNA relatedness with Aeromicrobium flavum DSM 19355T and Aeromicrobium tamlense DSM 19087T, respectively...

Membrane-disrupting antimicrobial peptides provide broad-spectrum defence against localized bacterial invasion in a range of hosts including humans. The most generally held consensus is that targeting to pathogens is based on interactions with the head groups of membrane lipids. Here we show that the action of LL-37, a human antimicrobial peptide switches the mode of action based on the structure of the alkyl chains, and not the head groups of the membrane forming lipids. We demonstrate that LL-37 exhibits two distinct interaction pathways: pore formation in bilayers of unsaturated phospholipids and membrane modulation with saturated phospholipids...

Seasonal reproduction is one of the major biotechnical and economic constraints of sheep production in temperate latitudes. Treatments using extra light followed by melatonin implants have been used satisfactorily in open barns, farms and artificial insemination centres to produce out-of-season sexual activity in rams. The aim of the present study is to explore the possibility of replacing melatonin implants with continuous light (LL), which was recently shown to increase LH secretion similar to melatonin and/or pinealectomy...

This study investigated the effects of feeding a mixed grain supplement and tenderstretching (TS) alpaca carcasses on meat quality. A total of 56 castrated 24month old alpacas were divided into two treatments (pasture-only, and pasture plus supplementation). Supplemented groups were fed a mixed grain ration in addition to ad lib pasture for 10weeks. Animals were slaughtered across two kill days (n=28). One half of each carcass was suspended by the pelvis (TS) prior to chilling, and the other half was Achilles tendon hung (AH)...

ABSTRACT: Animals generally adjust their behavior in response to bodily state (e.g., size and energy reserves) to optimize energy intake in relation to mortality risk, weighing predation probability against the risk of starvation. Here, we investigated whether brown trout Salmo trutta adjust their behavior in relation to energetic status and body size during a major early-life selection bottleneck, when fast growth is important. Over two consecutive time periods (P1 and P2; 12 and 23 days, respectively), food availability was manipulated, using four different combinations of high (H) and low (L) rations (i...

STUDY DESIGN: Retrospective cohort study at a single institution. OBJECTIVE: We aimed at estimating the rate of revision procedures and identify radiographic predictors of mechanical failure following adult spinal deformity surgery. SUMMARY OF BACKGROUND DATA: Mechanical failure rates following adult spinal deformity surgery range 12% to 37% in literature. While the importance of spinal and spino-pelvic alignment is well documented for surgical outcome and ideal alignment has been proposed as sagittal vertical axis (SVA) < 5 cm, pelvic tilt < 20° and lumbar lordosis (LL) = pelvic incidence ± 9°, the role of radiographic sagittal spine parameters and alignment targets as predictors for mechanical failure remains uncertain...

Our study combined 16S rRNA-pyrosequencing and whole genome sequencing to analyze the fecal metagenomes of the divergently selected lean (LL) and fat (FL) line chickens. Significant structural differences existed in both the phylogenic and functional metagenomes between the two chicken lines. At phylum level, the FL group had significantly less Bacteroidetes. At genus level, fourteen genera of different relative abundance were identified, with some known short-chain fatty acid producers (including Subdoligranulum, Butyricicoccus, Eubacterium, Bacteroides, Blautia) and a potentially pathogenic genus (Enterococcus)...

PURPOSE: In vivo studies have suggested that motor exercise can improve muscle regeneration after injury. Nevertheless, pre-clinical investigations still lack reliable tools to monitor motor performance over time and to deliver optimal training protocols to maximize force recovery. Here, we evaluated the utility of a murine robotic platform to (i) detect early impairment and longitudinal recovery after acute skeletal muscle injury and (ii) administer varying intensity training protocols to enhance forelimb motor performance...
