Homology-directed repair (HDR) maintains genomic integrity by eliminating lesions such as DNA double-strand breaks (DSBs), interstrand crosslinks (ICLs) and stalled replication forks and thus a deficiency in HDR is associated with genomic instability and cancer predisposition. The mechanism of HDR is best understood and most rigorously characterized in yeast. The inactivation of the fungal radiation sensitive 52 (RAD52) gene, which has both recombination mediator and single-strand annealing (SSA) activities in vitro, leads to severe HDR defects in vivo...

Atlantic lumpfish (Cyclopterus lumpus L.) is used as a biological delousing agent for sea lice (Lepeophtheirus salmonis K.) infestations in Norwegian aquaculture. Here, we present a study on the antibody response and vaccine side effects after intramuscular and intraperitoneal injection of lumpfish with two vaccines. Both vaccines contained bacterial antigens from atypical Aeromonas salmonicida A-layer types V and VI, Vibrio anguillarum serotype O1 and Moritella viscosa sp., but one vaccine contained a vegetable oil-based adjuvant, while the other contained a mineral oil-based adjuvant...

Nonpolar derivatives of heterocyclic aromatic screening hits like the non-selective sirtuin inhibitor splitomicin tend to be poorly soluble in biological fluids. Unlike sp(3) -rich natural products, flat aromatic compounds are prone to stacking and often difficult to optimize into leads with activity in cellular systems. The aim of this work was to identify anchor points for the introduction of sp(3) -rich fragments with polar functional groups into the newly discovered active (IC50  = 5 μM) but nonpolar scaffold 1,2-dihydro-3H-naphth[1,2-e][1,3]oxazine-3-thione by a molecular modeling approach...

Spatial synchrony, defined as correlated temporal fluctuations among populations, is a fundamental feature of population dynamics, but many aspects of synchrony remain poorly understood. Few studies have examined detailed geographical patterns of synchrony; instead most focus on how synchrony declines with increasing linear distance between locations, making the simplifying assumption that distance decay is isotropic. By synthesising and extending prior work, we show how geography of synchrony, a term which we use to refer to detailed spatial variation in patterns of synchrony, can be leveraged to understand ecological processes including identification of drivers of synchrony, a long-standing challenge...

Two 4-fluoro-L-glutamine diastereoisomers [(2S,4R)-4-FGln, (2S,4S)-4-FGln] were previously developed for positron emission tomography. Label uptake into two tumor cell types was greater with [(18)F](2S,4R)-4-FGln than with [(18)F](2S,4S)-4-FGln. In the present work we investigated the enzymology of two diastereoisomers of 4-FGln, two diastereoisomers of 4-fluoroglutamate (4-FGlu) (potential metabolites of the 4-FGln diastereoisomers) and another fluoro-derivative of L-glutamine [(2S,4S)-4-(3-fluoropropyl)glutamine (FP-Gln)]...

AIM: The aim of this study was to review the evidence regarding the pathophysiology of detrusor underactivity in the elderly. METHODS: A literature review was conducted in July 2016 using the Medline/Pubmed database limiting the search to works in English or French. RESULTS: The prevalence of detrusor underactivity has been reported to range from 8% to 48% depending on the definition used and the age of the population studied. Current data suggest that aging may itself be a causative factor of detrusor underactivity through myogenic dysfunctions (ultrastructural degeneration of the detrusor muscle) and neurogenic dysfunctions (by degeneration of efferent but mostly afferent innervation mechanisms)...

The deadlift is a compound full-body exercise that is fundamental in resistance training, rehabilitation programs and powerlifting competitions. Accurate quantification of deadlift biomechanics is important to reduce the risk of injury and ensure training and rehabilitation goals are achieved. This study sought to develop and evaluate deadlift exercise technique classification systems utilising Inertial Measurement Units (IMUs), recording at 51.2Hz, worn on the lumbar spine, both thighs and both shanks. It also sought to compare classification quality when these IMUs are worn in combination and in isolation...

Despite recent advances in cancer medication, malignant tumors continue to be the second leading cause of death worldwide. Furthermore, introducing a therapeutic compound with low-side effects as well as low-price for consumers is controversial. Recent efforts have been focusing on traditional medicines as a rich source of herbal agents. Curcumin, the major turmeric phytochemical, has been widely assessed as an anti-cancer compound in vitro and in vivo. However, the use of curcumin in cancer treatment has limitations because of its low solubility, poor tissue absorption, rapid metabolism and rapid systemic elimination...

It is now established that the central nervous system plays an important role in regulating whole body metabolism and energy balance. However, the extent to which sensory systems relay environmental information to modulate metabolic events in peripheral tissues has remained poorly understood. In addition, it has been challenging to map the molecular mechanisms underlying discrete sensory modalities with respect to their role in lipid metabolism. In previous work our lab has identified instructive roles for serotonin signaling as a surrogate for food availability, as well as oxygen sensing, in the control of whole body metabolism...

The anterior cingulate cortex (ACC) is known to be involved in effortful choice, yet its role in cost-benefit evaluation of qualitatively different rewards (more/less preferred), beyond magnitude differences (larger/smaller), is poorly understood. Selecting between qualitatively different options is a decision type commonly faced by humans. Here we assessed the role of ACC on a task that has primarily been used to probe striatal function in motivation. Rats were trained to stable performance on a progressive ratio schedule for sucrose pellets and were then given sham surgeries (control) or excitotoxic NMDA-lesions of ACC...

Amidst intensifying policy concerns with children's wellbeing and development, healthcare professionals are required not only to assess risk of abuse and neglect, but to manage risk of 'poor parenting' more broadly. Drawing on 15 in-depth interviews and non-participant observations of 61 professional-family interactions, across four preventative public health services for children in the Netherlands, we explored how professionals accomplished such risk work amid intractable uncertainties. Building inferences from brief encounters with families, professionals gauged the extent to which they trusted parents to care 'appropriately'...

REVIEW
Deborah Christie, Sarah Glew
The art of communication at times seems at odds with the science of medicine. Poor communication is associated with risks for patient and physician. Communication skills are highly relevant for haematologists and are associated with increased physician and patient satisfaction, positive psychosocial outcomes and possible health outcomes. Medical communication training has recently become widespread but is largely restricted to junior medical professionals. In haematology, the proliferation of high quality communication skills is low and there are few interventions catering for the required skillset...
