Nanoformulation and Preclinical Evaluation of Dihydroartemisinin–Lumefantrine and Primaquine as Combined Antimalarial Therapy

open access: yesJournal of Nanotechnology, Volume 2025, Issue 1, 2025.
The World Health Organization recommends artemisinin‐based combinations for uncomplicated malaria treatment. Artemether and lumefantrine (LUM) are the first‐line treatments, with artemether serving as a prodrug of dihydroartemisinin (DHA), while primaquine (PQ) is primarily used as a prophylactic drug.

Gonadal Maturation and Reproductive Timing in Batch Spawning Tropical Cypriniform Fishes Lobocheilos ovalis, Rasbora argyrotaenia and Tor tambra

open access: yesAquaculture, Fish and Fisheries, Volume 4, Issue 6, December 2024.
ABSTRACT This study is the first to investigate the reproductive traits of Lobocheilos ovalis (n = 621), Rasbora argyrotaenia (n = 507) and Tor tambra (n = 138) through detailed gonad histology. We collected L. ovalis and R. argyrotaenia specimens from September 2017 to August 2019 and T.

Inception of vented water trees in high voltage XLPE cable insulation: Effect of inorganic contaminations inside the semiconductive material

open access: yesJournal of Applied Polymer Science, Volume 141, Issue 43, November 15, 2024.
A mechanism causing the inception of vented water trees growing from the semiconductive screen into the XLPE insulation of wet‐design subsea power cables is revealed. Large voids containing impurities, for example, NaCl in the bulk of the semiconductive screen are connected to the water tree inception site by a porous region of degraded polymer.

Reprocessable and Mechanically Tailored Soft Architectures Through 3D Printing of Elastomeric Block Copolymers

open access: yesAdvanced Functional Materials, Volume 34, Issue 48, November 26, 2024.
This study demonstrates a straightforward and scalable additive manufacturing technique enabling the fabrication of soft, hierarchically ordered structures with tunable local and macroscopic properties. 3D printing leads to a high degree of alignment of block copolymer nanostructures along a controlled print path, leading to 85 × mechanical anisotropy ...

Highly Anisotropic Thermally Conductive Dielectric Polymer/Boron Nitride Nanotube Composites for Directional Heat Dissipation

open access: yesSmall, Volume 20, Issue 48, November 27, 2024.
Nanocomposites with directionally aligned boron nitride nanotubes (BNNTs) are produced using melt‐compounding and in situ fibrillation, followed by sintering. These nanocomposites exhibit a significant improvement in thermal properties, achieving an in‐plane thermal conductivity (K‖) of 1.8 Wm−1 K−1, a 450% increase.

Dexmedetomidine preconditioning reduces ischaemia–reperfusion injury in equine model of large colon volvulus

open access: yesEquine Veterinary Journal, Volume 56, Issue 6, Page 1251-1258, November 2024.
Abstract Background Large colon volvulus is a cause of colic in horses with high morbidity and mortality when not promptly treated. More treatment options are needed to improve the outcome of these cases by protecting against the damage caused by ischaemia and reperfusion injury.

Quantification of porcine lower thoracic spinal cord morphology with intact dura mater using high‐resolution μCT

open access: yesJournal of Neuroimaging, Volume 34, Issue 6, Page 646-663, November/December 2024.
Abstract Background and Purpose Spinal cord stimulation (SCS) is approved by the Food and Drug Administration for treating chronic intractable pain in the back, trunk, or limbs through stimulation of the dorsal column. Numerous studies have used swine as an analog of the human spinal cord to better understand SCS and further improve its efficacy.
