The Asian tiger mosquito Aedes albopictus (Skuse) is rapidly increasing its global range and importance in transmission of chikungunya and dengue viruses. We tested pellet formulations of a monomolecular film (Agnique) and (S)-methoprene (Altosid) under laboratory and field conditions. In the laboratory, Agnique provided 80% control for 20 days, whereas Altosid, in combination with Agnique, provided 80% control for > 60 days. During field trials, the 1:1 pellet ratio of combined products provided > 95% control for at least 32 days and 50% control for at least 50 days. Altosid remained effective after a 107-day laboratory-induced drought, suggesting that the product serves as a means of control during drought conditions and against spring broods in temperate regions. Agnique and Altosid, when used in tandem for cryptic, difficult-to-treat locations, can provide long-term control of Ae. albopictus larvae and pupae. The possible additive or synergistic effects of the combined products deserve further investigation.

Stretching, Isometrics, and Aerobic Exercise for Decreasing Blood Pressure Post-Exercise: A Randomized Cross-Over Study.
Appl Physiol Nutr Metab
January 2025
University of Saskatchewan, Saskatoon, Saskatchewan, Canada;
We compared stretching, isometrics, and aerobic exercise for effectiveness in decreasing blood pressure post-exercise. Using a randomized crossover design, 5 males and 4 females (21.3y; normotensive) participated in four 30-minute sessions on separate days: static stretching (30s stretches, major muscle groups), isometric exercise, aerobic cycling (75% VO2peak), and control (rest), with blood pressure and heart rate measured before exercise (or rest) and for 60 minutes post-exercise (or rest).

Objective: To compare the effectiveness of ear acupuncture with laser and needles in the treatment of anxiety in university students in the post-pandemic context of Covid-19, as well as to evaluate the possible symptoms or adverse reactions triggered by the interventions.
Method: Randomized clinical trial carried out with 126 university students, allocated to the "Needle" (control) and "Laser" (experimental) groups. Five ear acupuncture sessions were performed.
Case-area targeted interventions and free chlorine residual in household drinking water: An observational cohort study during a cholera outbreak in Northeast Nigeria.

Background: Cholera outbreaks are surging worldwide. Growing research supports case-area targeted interventions (CATIs), whereby teams provide a package of interventions to case and neighboring households, as an effective strategy in cholera outbreak control, particularly in humanitarian settings. While research exists on individual CATI interventions, research gaps exist on outcomes of integrated interventions during CATI responses.

Objective: To characterize structural integrity of the lumbosacral enlargement and conus medullaris within one month after spinal cord injury (SCI).
Methods: Lumbosacral cord MRI data were acquired in patients with sudden onset (<7 days) SCI at the cervical or thoracic level approximately one month after injury and in healthy controls. Tissue integrity and loss were evaluated through diffusion tensor (DTI) and T2*-weighted imaging (cross-sectional area [CSA] measurements).
In utero exposure to experimental maternal asthma alters fetal airway development in sheep.
Exp Physiol

Robinson Research Institute, University of Adelaide, Adelaide, South Australia, Australia.
The mechanisms linking maternal asthma (MA) exposure in utero and subsequent risk of asthma in childhood are not fully understood. Pathological airway remodelling, including reticular basement membrane thickening, has been reported in infants and children who go on to develop asthma later in childhood. This suggests altered airway development before birth as a mechanism underlying increased risk of asthma in children exposed in utero to MA.
