Background: Archery is a unique sport requiring simultaneous physical and psychological focusing for precisely hitting the small, distant target. Thus, in this sport, the effects of stress and anxiety on success might be more pronounced as a slight deviation in aiming may translate into a large error in meeting the target. Therefore, the current study aimed to assess the interrelationship between anxiety, cortisol awakening response (CAR), cortisol levels during the shooting period, and success in professional male archers during a national tournament.
Methods: Archers (16-20 years old, male, N.=20) shooting with recurve bow participated in the current study during the indoor archery championship. For the assessment of CAR, salivary samples were collected at 0- (wake up), 30-, 45- and 60-min postawakening on three consecutive days, namely qualification, individual elimination, and team shooting days. On the first two days of the shootings (i.e., qualification and elimination), shooting salivary samples were collected at 30 and 15 minutes before the shootings, at half-time and just after the shootings. State and trait anxiety inventory were filled in on the day of registration (the day before qualification shootings).
Results: CAR, measured as the area under the curve (AUC), was higher on the elimination day (P=0.038) compared to the qualification day. Shooting cortisol levels were also higher on the elimination day compared to the qualification day (P=0.004). Archers having high rankings on qualification day also had higher success rates on elimination day (r=0.963, P<0.001).
Conclusions: Moderately increased state anxiety, higher CAR, and elevated shooting cortisol levels appear to be the integral components of the elimination stage during a real competition in archery. Thus, assessment of secretion dynamics of cortisol appears to be a valuable objective tool for understanding the neuroendocrine control during the competition days.

Background: Fall prevention programmes are essential interventions in societies with aging populations. This study assessed the fall rate and other health outcomes, as well as the cost-effectiveness of a home-based fall prevention programme for community-dwelling older people. In a single home visit, trained physical or occupational therapists performed fall risk assessments, eliminated environmental risk factors, and provided tailored exercises.

Background: Multidose iodinated contrast media (ICM) injectors have shown promise in reducing ICM waste. This study aims to evaluate the impact of patient volume on ICM waste reduction in multidose injectors.
Methods: CT studies performed over one-year period with a multidose injector at our emergency CT unit.

Recombineering (recombination-mediated genetic engineering) is a powerful strategy for bacterial genomic DNA and plasmid DNA modifications. CoS-MAGE improved over MAGE (multiplex automated genome engineering) by co-electroporation of an antibiotic resistance repair oligo along with the oligos for modification of the Escherichia coli chromosome. After several cycles of recombineering, the sub-population of mutants were selected among the antibiotic resistant colonies.

Background Alveolar echinococcosis (AE) is a fatal zoonotic disease distributed mainly in the Northern Hemisphere. At present, its curative treatment relies on surgery, and the development of effective drugs is needed. We previously demonstrated the anti-echinococcal effect of atovaquone (ATV) as a mitochondrial complex III inhibitor in both in vitro and in vivo experiments.

Background & Aims: The dynamics of HBV viral load (VL) in patients with chronic hepatitis B (CHB) on nucleos(t)ide analogue (NA) treatment and its relationship with liver disease are poorly understood. We aimed to study longitudinal VL patterns and their associations with CHB clinical outcomes.
Methods: Utilising large scale, routinely collected electronic health records from six centres in England, collated by the National Institute for Health and Care Research Health Informatics Collaborative (NIHR HIC), we applied latent class mixed models to investigate VL trajectory patterns in adults receiving NA treatment.
