Diosgenin and solasodine-based saponins and sapogenines—Effects of structural modifications on Panagrellus redivivus, Spodoptera littoralis and Trichoderma reesei
Published 2025-01-01“…We show that the bioactivity is highly variable, depending not only on the tested organisms, but also on the glycosylation pattern. Especially 26-amino-(22R,25R)-furost-5-en-3β-ol exhibited high nematocidal (75 % mortality rate), anti-herbivorous (feeding rate reduced to 0.4 % leaf area/min) as well as anti-fungal properties (47 % increased anti-fungal activity compared to solasodine) whilst the other tested compounds exhibited only moderate activities.…”

A novel wound dressing material with prolonged action
Published 2019-06-01“…Acute toxicity pharmacological studies of material test-samples containing 6 % and 9 % active chlorine in a single application on the skin of rats and rabbits found that these applications did not lead to deaths, as well as changes in their behavioral pattern, consumption of feed and water. The epithelization rate of uninfected wound surface in application of dressings containing both sodium N-chlorosulfonamide and N, N-dichlorosulfonamide was significantly, on average 1.5 times, faster at the end of the observational period (day 14) in comparison with the control group animals. …”

Non-uniform temperature fields and debonding of a long-span CFST arch bridge under coupled environmental actions
Published 2025-12-01“…Experimental and theoretical analyses yielded several significant findings: (1) During the hydration exothermic phase, the temperature field at concrete center exhibited a tri-linear distribution pattern (characterized by rapid initial rise, subsequent decline, and final stabilization), with the ascending rate significantly exceeding the descending rate; temperatures exceeded 50°C between 25 and 73 h post-placement. (2) The external steel tube temperature demonstrated sinusoidal diurnal variations during and post-hydration, closely correlating with ambient temperature fluctuations; after hydration, concrete temperatures also followed sinusoidal diurnal distributions, with amplitudes increasing proportionally to radial distance from the center. (3) A pronounced radial temperature gradient from center to surface manifested during hydration, reaching a maximum differential of 40°C; the temperature gradients substantially decreased to 7°C after hydration. (4) Longitudinal stress differentials between the interface steel tube and concrete measured 42.5 MPa (sun-exposed side) and 74.2 MPa (shadowed side), while radial stress differentials were −1.37 MPa and −0.34 MPa, respectively. (5) The temperature field model demonstrated a tri-linear distribution pattern with an effective influence depth of D/8 to D/4 (where D represents steel tube diameter); the temperature constant exhibited significant temporal dependency on environmental conditions and hydration heat evolution. (6) Although longitudinal relative slip occurred at the steel-concrete interface during placement, no void was detected.…”
