Article Synopsis
- - The study examined the effects of an 8-minute dermal suction treatment on joint range of motion (ROM) and muscle stiffness in 15 participants, focusing on the quadriceps femoris.
- - Results showed that hip extension ROM improved significantly right after the treatment and at 60 and 120 minutes, but returned to baseline by 30 minutes and did not last beyond 2 hours.
- - Passive muscle stiffness and knee flexion ROM did not show any significant changes at any time point after the treatment, indicating that the main benefit was limited to hip extension ROM for a short period.

Article Synopsis
- The study aimed to investigate how dermal suction affects the mechanical properties of muscles and joints, specifically focusing on the calves of 24 subjects.
- Researchers measured passive plantar flexion torque and the shear wave velocity of the medial gastrocnemius muscle at different ankle angles before and after applying dermal suction.
- Results indicated that dermal suction significantly increased passive muscle stiffness but had little to no effect on passive joint stiffness.
The data presented here are related to the research paper entitled "Hydroxylated furanoditerpenoids from the pupal case produced by the bruchid beetle inside the seed of " (Akihara et al., 2018) [1]. In this data article, we provide high-performance liquid chromatography (HPLC) profiles of seven undescribed hydroxylated furanoditerpenoids, caesalsauteolide, 2-hydroxycaesaljapin, 2,7-dihydroxycaesaljapin, 2-hydroxycaesalacetal, caesalsauterol, 6-acetylcaesalsauterol, norcaesalsauterol isolated from the pupal cases produced by and four known compounds, caesaljaponin A (Kamikawa et al.

The hydroxylated furanoditerpenoids found in the pupal cases were not present in the seeds of the host plant. Caesalacetal and caesaljapin obtained from the intact seeds exhibited larvicidal activity against the larvae of Aedes albopictus, while the hydroxylated furanoditerpenoids isolated from the pupal cases were inactive.

(Moraceae). The structures were determined on the basis of spectroscopic data, as well as X-ray crystallographic analysis.
