Manipulation of magnetisation with ultrashort laser pulses is promising for information storage device applications. The dynamics of the magnetisation response depends on the energy transfer from the photons to the spins during the initial laser excitation. A material of special interest for magnetic storage are FePt nanoparticles, for which switching of the magnetisation with optical angular momentum was demonstrated recently. The mechanism remained unclear. Here we investigate experimentally and theoretically the all-optical switching of FePt nanoparticles...

Most of the European Union (EU) and European Economic Area (EEA) is considered a region of very low hepatitis A virus (HAV) endemicity; however, geographical differences exist. We did a systematic review with the aim of describing seroprevalence and susceptibility in the general population or special groups in the EU and EEA. We searched databases and public health national institutes websites for HAV seroprevalence records published between Jan 1, 1975, and June 30, 2014, with no language restrictions. An updated search was done on Aug 10, 2016...

BACKGROUND: The understanding of genomic and physiological mechanisms related to how organisms living in extreme environments survive and reproduce is an outstanding question facing evolutionary and organismal biologists. One interesting example of adaptation is related to the survival of mammals in deserts, where extreme water limitation is common. Research on desert rodent adaptations has focused predominantly on adaptations related to surviving dehydration, while potential reproductive physiology adaptations for acute and chronic dehydration have been relatively neglected...

The ambulatory care of patients with Parkinson's disease (PD) in Germany has been established for a long time. As the prevalence of Parkinson's disease continues to increase, the outpatient neurological sector is becoming more and more important and needs to adapt itself to current needs. This includes an optimization of the care structures for Parkinson's patients as well as adequate concepts for the execution of differentiated diagnostics and therapy. For many patients care is provided by non-specialized neurological practices or general practitioners, without exchange of views with neurologists or a specialized university outpatient clinic for movement disorders...

Conventional HR-EBSD is attracting much interest due to its ability of measuring relative crystal misorientations and microstresses with great accuracy. However, this technique needs the use of simulated patterns in order to get absolute values of crystal orientation and stresses and thus expand its use to intergranular analyses. Simulation-based approaches have shown many limitations due to the poor correlation with the real patterns specially when Bragg simulations are considered. This paper presents an improved algorithm based on gradient-based correlation techniques that makes simulation-based HR-EBSD possible...

Coronary artery anomalies, particularly anomalous aortic origin of a coronary artery with an interarterial course, are associated with sudden cardiac arrest or death in the young. There is paucity of data on risk stratification and longitudinal follow up is lacking in these patients. Collaboration and sharing of data among specialized centers might shed much needed light in this complex problem.

Elasmobranch hematology continues to reveal new peculiarities within this specialized field. This report compares total hematologic values from the same white-spotted bamboo sharks (Chiloscyllium plagiosum) housed in different environments. We compared the hemograms one year apart, using a standardized Natt-Herrick's technique. The total white blood cell (WBC) counts of the sharks were statistically different between the two time points (initial median total WBC count = 18,920 leukocytes/μl, SD = 8,108; 1 year later total WBC count = 1,815 leukocytes/μl, SD = 1,309)...

REVIEW
Uday C Ghoshal
Chronic constipation (CC) is a common problem in the community and in gastroenterology practice all over the world including India. After release of Rome IV guidelines in April 2016, there is increasing interest among gastroenterologists and physicians in India to look into special issues on CC in the Indian perspective. There are important differences in the bowel habit, definition, epidemiology, and pathophysiology including dietary factors and management of CC in India as compared to the West. As severity and frequency of abdominal pain, a symptom essential to diagnose constipation-predominant irritable bowel syndrome (IBS-C) rather than functional constipation (FC), is less common among Indian patients, FC is commoner than IBS-C in India...

Many knock-out/knock-in mouse and rat strains have been produced by genome editing techniques using engineered endonucleases, including zinc finger nuclease (ZFN), transcription activator-like effector nuclease (TALEN), or clustered regularly interspaced short palindromic repeats (CRISPR)-Cas9. Microinjection of engineered endonucleases into pronuclear-stage embryos is required to produce genome-edited rodents and the development of easy, rapid, and high-efficiency methods that do not require special skills such as microinjection is needed...

Perceived devaluation has been shown to have adverse effects on the mental and physical health outcomes of people who use drugs. However, the impact of perceived devaluation on sexually transmitted infections (STI) testing uptake among street-involved youth, who face multiple and intersecting stigmas due to their association with drug use and risky sexual practices, has not been fully characterized. Data were obtained between December 2013 and November 2014 from a cohort of street-involved youth who use illicit drugs aged 14-26 in Vancouver, British Columbia...

Genome integrity relies on the ability of the replisome to navigate ubiquitous DNA damage during DNA replication. The Escherichia coli replisome transiently stalls at leading-strand template lesions and can either reinitiate replication downstream of the lesion or recruit specialized DNA polymerases that can bypass the lesion via translesion synthesis. Previous results had suggested that the E. coli replicase might play a role in lesion bypass, but this possibility has not been tested in reconstituted DNA replication systems...

REVIEW
Bochra Tourki, Ganesh Halade
In response to myocardial infarction (MI), time-dependent leukocyte infiltration is critical to program the acute inflammatory response. Post-MI leukocyte density, residence time in the infarcted area, and exit from the infarcted injury predict resolving or nonresolving inflammation. Overactive or unresolved inflammation is the primary determinant in heart failure pathology post-MI. Here, our review describes supporting evidence that the acute inflammatory response also guides the generation of healing and regenerative mediators after cardiac damage...

Increased survival of patients with congenital diaphragmatic hernia has created a unique cohort of children, adolescent, and adult survivors with complex medical and surgical needs. Disease-specific morbidities offer the opportunity for multiple disciplines to unite together to provide long-term comprehensive follow-up, as well as an opportunity for research regarding late outcomes. These children can exhibit impaired pulmonary function, altered neurodevelopmental outcomes, nutritional insufficiency, musculoskeletal changes, and specialized surgical needs that benefit from regular monitoring and intervention, particularly in patients with increased disease severity...

Acute ischaemic stroke accounts for 6.5 million deaths per year, and by 2030 will result in the annual loss of over 200 million disability-adjusted life years globally. There have been considerable recent advances in the gold standard of acute ischaemic stroke treatment, some aspects of which-aspirin to prevent recurrence, and treating patients in specialized stroke wards-are widely applicable. Recanalization of the occluded artery through thrombolysis and/or endovascular thrombectomy is restricted to only a small proportion of patients, due to contra-indications and the costs associated with establishing the infrastructure to deliver these treatments...
