Background: The Asian long-horned beetle [ALB; Anoplophora glabripennis (Motschulsky)] is an invasive, wood-boring insect posing significant economic and ecological threats to the deciduous forests of North America. An efficacious and environmentally acceptable chemical control technique is a requirement of a comprehensive, integrated response strategy.
Results: Results of this study demonstrate statistically significant, concentration-dependent effects of azadirachtins, a family of natural compounds derived from the neem tree, on both ALB larval and adult life stages. Growth inhibitory effects on ALB larvae were greatest on early life stages. Significant effects on adults included inhibition of female feeding, oviposition effort and fecundity for adults exposed to azadirachtins via maturation feeding on systemically loaded twigs.
Conclusion: These quarantine laboratory experiments verify multi-mechanistic, deleterious effects on both larval and adult life stages of ALB, an exotic, invasive insect pest of critical importance in North America. Field efficacy studies are required to further understand dose acquisition by larval and adult ALB life stages following systemic injections to host trees under semi-operational use scenarios. Such studies could also be used to test postulates regarding optimal deployment strategies to meet objectives such as slowing the spread of this pest and protection of high-value deciduous forest resources. © 2017 Her Majesty the Queen in Right of Canada Pest Management Science © 2017 Society of Chemical Industry.

Research has shown that married individuals live longer lives than unmarried women and men. A smaller number of studies have included non-marital cohabitation and have found that their mortality falls between the married and other unmarried groups. There are indications that the cohabiting population is diverse in terms of mortality risk, yet very little is known about how the association is related to age and stages of the life course.

Objectives: The purpose of the present study was to investigate the differential impact of disease activity and severity on functional status and patient satisfaction in rheumatoid arthritis (RA) using cluster analysis on data from the FRANK registry.
Methods: Data from 3,619 RA patients in the FRANK registry were analysed. Patients were grouped using hierarchical and k-means cluster analyses based on age, physician's global assessment (PhGA), patient's pain assessment (PtPA), and Steinbrocker stage.

Selective breeding is a potent method for developing strains with enhanced traits. This study compared the growth performance and stress responses of the genetically improved Abbassa Nile tilapia strain (G9; GIANT-G9) with a local commercial strain over 12 weeks, followed by exposure to stressors including high ammonia (10 mg TAN/L), elevated temperature (37 °C), and both for three days. The GIANT-G9 showed superior growth, including greater weight gain, final weight, length gain, specific growth rate, and protein efficiency ratio, as well as a lower feed conversion ratio and condition factor compared to the commercial strain.

Background: Girls' physical activity and healthful eating behaviors decline throughout adolescence. These trajectories may be linked to the underdevelopment of exercise and healthful eater identities. Youth programs might consider prioritizing identity development as an innovative health promotion strategy, especially during the formative preadolescent life stage.

Background: Primary breast lymphoma is extremely rare and constitutes approximately 1% of all non-Hodgkin's lymphomas (NHL). Only 1-5% of them are Burkitt type. We present a case of childhood primary breast Burkitt lymphoma (BL).
