The incompatible insect technique based on is a promising alternative to control mosquito-borne diseases, such as dengue fever, malaria, and Zika, which drives wild female mosquitoes sterility through a mechanism cytoplasmic incompatibility. A successful control program should be able to withstand the perturbation induced by the immigration of fertilized females from surrounding uncontrolled areas. In this paper, we formulated a system of delay differential equations, including larval and adult stages, interfered by -infected males.

When losing balance, upper-body movements serve as mechanical aids to regain stability. However, it remains unclear how these movements contribute to dynamic stability during recovery from a lateral loss of balance while walking with arm restriction. We aimed to (i) quantify the effect of arm restriction on gait stability and upper-body velocities and (ii) characterize upper-body kinematic strategies in response to lateral surface translations under different arm restriction conditions.

Article Synopsis
- The study focuses on the interaction between the bioactive ligand yohimbine (Yoh) and the protein myoglobin (Mb), highlighting its importance in pharmacokinetics and pharmacodynamics.
- Through emission spectroscopy, it was found that Yoh has a binding constant of 10 M and a 1:1 binding site ratio with Mb, while structural changes in Mb were observed using circular dichroism.
- The validation of binding interactions was supported by molecular dynamics simulations, showing that the Mb-Yoh complex remains stable over time, which is crucial for understanding drug design and bioavailability.
Biomechanical responses following compelled forward versus backward body shift: How aging and perturbation direction alter balance recovery?

Falls are a significant health risk in older adults, and forward and backward falls each account for more than 40 % of falls. Dynamic stability, limb support, and impact energy absorption are crucial balance regulatory components and likely vary with the direction of imbalance. Understanding how perturbation direction influences these key components of balance stability regulation is crucial.

The basolateral amygdala (BLA) is a dynamic brain region involved in emotional experiences and subject to long-term plasticity. The BLA also modulates activity, plasticity, and related behaviors associated with other brain regions, including the mPFC and hippocampus. Accordingly, intra-BLA plasticity can be expected to alter both BLA-dependent behaviors and behaviors mediated by other brain regions.
