Escape is a life critical defensive behaviour. One potential escape strategy is using ultrafast movements to relocate quickly. These movements do not rely solely on muscle activation and are beneficial for ectotherms at low temperatures when muscle performance is constrained.

This study aimed to utilize the nonnegative matrix factorization (NNMF) algorithm for muscle synergy analysis, extracting synergy structures and muscle weightings and mining biomarkers reflecting changes in muscle fatigue from these synergy structures. A leg press exercise to induce fatigue was performed by 11 participants. Surface electromyography (sEMG) data from seven muscles, electrocardiography (ECG) data, Borg CR-10 scale scores, and the z-axis acceleration of the weight block were simultaneously collected.

Objective: To investigate the efficacy of transcranial ultrasound stimulation (TUS) combined with Fastigial nucleus stimulation (FNS) on cerebral blood flow and limb function in patients in the acute phase of ischemic stroke.

Methods: A total of 90 patients in the acute phase of ischemic stroke were randomly divided into an FNS, TUS, and TUS + FNS group (30 patients each), and all patients also received conventional treatment. The FNS group was treated with FNS alone.

Enhanced attachment ability is common in plants on islands to avoid potential fatal passive dispersal. However, whether island insects also have increased attachment ability remains unclear. Here we measured the attachment of a flightless weevil, , from tropical islands, and compared it with documented arthropods from the mainland.

Article Synopsis
  • A study was conducted to assess the impact of combining pulmonary rehabilitation with diaphragm pacemaker therapy on diaphragm function in patients who are severely ill and on mechanical ventilation.
  • 40 patients were split into two groups: one received standard care (control group), while the other (experimental group) received additional diaphragm pacemaker therapy along with standard care.
  • Results showed that after 30 days, the experimental group had more significant improvements in health indicators and shorter hospital stays compared to the control group, with no adverse events reported.

The sensitivity of animal photoreceptors to different wavelengths of light strongly influence the perceived visual contrast of objects in the environment. Outside of the human visual wavelength range, ultraviolet sensitivity in many species provides important and behaviourally relevant visual contrast between objects. However, at the opposite end of the spectrum, the potential advantage of red sensitivity remains unclear.

Adaptations to control heat transfer through the integument are a key component of temperature regulation in animals. However, there remain significant gaps in our understanding of how different optical and morphological properties of the integument affect heating rates. To address these gaps, we examined the effect of reflectivity in both ultraviolet-visible and near-infrared wavelengths, surface rugosity (roughness), effective area (area subjected to illumination) and cuticle thickness on radiative heat gain in jewel beetles (Buprestidae).

Although Cynomorium songaricum Rupr. polysaccharide (CSP) has been examined for its effects on glucose regulation, its underlying mechanism is still unclear. To address this issue, a MS-based lipidomics strategy was developed to gain a system-level understanding of the mechanism of CSP on improving type 2 diabetes mellitus (T2DM).

The cuticle plays an important role in the evolutionary success of insects. Many studies on insect cuticles have reported a soft, resilin-rich endocuticle. However, a recent study indicated the presence of a sclerotised endocuticle in the weevil Pachyrhynchus sarcitis kotoensis, which contradicts former knowledge.

Robust body armor is one of many anti-predator strategies used among animal taxa. The exoskeleton of insects can serve as the secondary defense mechanism in combination with the primary defense such as warning color. Aposematic weevils advertise their unprofitability and use their robust exoskeleton for effective defense against lizard predators.

Anti-predator strategies are significant components of adaptation in prey species. Aposematic prey are expected to possess effective defences that have evolved simultaneously with their warning colours. This study tested the hypothesis of the defensive function and ecological significance of the hard body in aposematic weevils pioneered by Alfred Russel Wallace nearly 150 years ago.

We have experimentally investigated the jitter time of a GaAs photoconductive switch (PCSS) when it is triggered by a laser pulse with 30 ns pulse width and 1064 nm wavelength. It is found that the jitter time decreases as the incident laser pulse energy increases from 0.40 to 1.
