Article Abstract
Background/objectives: Prior work regarding post-activation performance enhancement (PAPE) has shown that various resistance training methods and conditioning activities may induce a PAPE effect such as free weight resistance, accommodating resistance or isoinertial resistance. However, the accommodating resistance and other types of resistance have rarely been directly compared. Thus, the aim of this study was to compare the effects of two different conditioning activities (CA) - a trap bar deadlift with (FW + AR condition) or without (FW condition) accommodating resistance - on subsequent squat jump (SJ) performance after a short rest interval of 90s.
Methods: The study had a cross-over design and fifteen strength trained males (mean age: 22.9 ± 2.1 years; mean relative strength level 2.01 ± 0.27 kg/body mass) participated in one familiarization, two experimental and one control session (CNTR condition). Two CAs were implemented throughout the study - a single set of 3 repetitions of a trap bar deadlift at 80 % of 1RM using solely free weight resistance or with the addition of approximately 15 % of 1RM elastic band tension. The SJ measurements were performed at the baseline and 90s after CAs.
Results: The FW + AR condition significantly improved subsequent SJ performance (p < 0.05, effect size 0.34) whereas the FW and CNTR conditions were found to be ineffective to acutely enhance performance.
Conclusions: Our results suggest that the addition of accommodating resistance is superior to free weight resistance in order to acutely improve jump performance after a 90s rest interval. To observe the performance enhancement effect with solely free weight resistance it should be considered to introduce alteration in loading strategies or possibly lengthening the rest interval.

Just as Gregor Mendel's laws of inheritance laid the foundation for modern genetics, the emergence of Clustered Regularly Interspaced Short Palindromic Repeats (CRISPR)/Cas systems has catalyzed a new era in precision genome engineering. CRISPR/Cas has revolutionized rice ( L.) breeding by enabling precise, transgene-free edits to improve yield, nutrition, and stress tolerance.

The emergence of multidrug resistance in Plasmodium falciparum poses a serious threat to antimalarial treatment, particularly with growing resistance to artemisinin-based combination therapies (ACTs) and partner drugs like piperaquine. Mutations in key proteins, such as PfCRT (P. falciparum chloroquine resistance transporter) and PfDHFR (P.

Solid-state lithium-ion batteries have raised considerable attention due to their great potential for the development of new energy storage devices with high energy density and safety. However, enhancing ion conductivity in solid-state electrolytes stands as a pivotal challenge for the large-scale commercialization of next-generation lithium-ion batteries. Here, a high-pressure strategy is reported to achieve the significant enhancement of lithium-ion conductivity by 2 orders of magnitude and the disappearance of grain boundary resistance in polyoxometalate LiPWO electrolyte via an irreversible phase transition from Keggin to bronze structure.

Developing next-generation anodes with high silicon (Si) contents requires thoughtful embedment of Si particles in protective media, mainly carbonaceous materials. However, it has been challenging to simultaneously realize optimal electrical conduction, structural integrity, and low-cost synthesis for advancing Si-carbon materials. In this work, we addressed these challenges by synthesizing a composite, where commercial Si nanoparticles are embedded in a dual carbon framework via a facile solution mixing and annealing process.

pathogenicity islands (SaPIs) are prototypical members of the phage-inducible chromosomal islands (PICI) family. These elements redirect helper phage capsid assembly to produce smaller capsids, accommodating the satellite genome while excluding the phage genome. This study identifies how SaPIpT1028 mediates capsid redirection through a unique gene, (redirecting capsid morphogenesis).
