A Degradable Device for Sustainable Capillary Blood Sampling

Advanced Materials Technologies, EarlyView.
The device features a compostable 3D‐printed storage compartment for liquid blood collection and a degradable, poly(ɛ‐caprolactone)‐coated magnesium microneedle patch hidden within a suction cup. Manual compression deploys the MNs, creating small skin punctures, and the subsequent release of compression generates the negative pressure required for ...

Role of nucleus accumbens dopamine 2 receptors in motivating cocaine use in male and female rats prior to and following the development of an addiction-like phenotype

Frontiers in Pharmacology, 2023
A hallmark of cocaine use disorder (CUD) is dysfunction of dopamine signaling in the mesolimbic pathway, including impaired dopamine 2 (D2) receptor signaling.

Smart Ticket Protection: An Architecture for Cyber-Protecting Physical Tickets Using Digitally Signed Random Pattern Markers

, 2018
In order to counter forgeries of tickets for public transport or mass events, a method to validate them, using printed unique random pattern markers was developed. These markers themselves are unforgeable by their physically random distribution.

Interactions of Interaural Time and Level Differences in Spatial Hearing with Cochlear Implants

Advanced Science, EarlyView.
Differences in timing (ΔT) are weighted heavily compared to differences in loudness (ΔL) in binaural hearing with cochlear implants. Abstract Normally hearing humans can localize sound sources quite accurately, with minimum audible angles as small as 1°. To achieve this, these auditory pathways combine information from multiple acoustic cues, including

Icaritin Ameliorates Cisplatin‐Induced Mitochondrial Metabolic Dysfunction‐Associated Nephrotoxicity and Synergistically Potentiates Its Antitumor Efficacy

Advanced Science, EarlyView.
In this study, scRNA‐seq and chemoproteomics are integrated to characterize CDDP‐bound proteins at single‐cell resolution in tumor‐bearing mice. Additionally, the research demonstrates that ICA alleviates CDDP‐induced nephrotoxicity while enhancing its chemotherapeutic efficacy.

Crystallographic Study of DNA T‐Junction via Crystal Engineering

Angewandte Chemie, EarlyView.
Engineered DNA crystals provides a platform to regularly arrange guest molecules for crystallographic study. Herein, the 3D structure of T‐junction, a commonly used motif in DNA nanotechnology, was revealed. Abstract Engineering DNA crystals is the primary motivation for structural DNA nanotechnology.

Effects of Isometric Hip Extension Using Thera-band on Hip Muscle Activities During Side-lying Hip Abduction Exercise in Participants With Gluteus Medius Weakness

Physical Therapy Korea
Background: Weakness of gluteus medius (Gmed) is related with musculoskeletal disorders. Individuals who experience weakness in the Gmed may activate the tensor fasciae latae (TFL) as a compensatory mechanism. Application of isometric hip extension (IHE)

Differential Power Analysis of HMAC Based on SHA-2, and Countermeasures [PDF]

, 2007
The HMAC algorithm is widely used to provide authentication and message integrity to digital communications. However, if the HMAC algorithm is implemented in embedded hardware, it is vulnerable to side-channel attacks. In this paper, we describe a DPA attack strategy for the HMAC algorithm, based on the SHA-2 hash function family.

Integrated ERK‐PKA‐YAP/TAZ‐SHH Signaling Orchestrates Cortical Radial Glia Identity and Lineage Diversification

Advanced Science, EarlyView.
This study shows that ERK/PKA upregulation in mammalian cortical radial glia (RGs) sustains neurogenesis and suppresses gliogenesis. YAP/TAZ activation promotes ependymal cell formation, while enhanced SHH‐SMO signaling induces astrocyte, oligodendrocytes, and olfactory bulb interneuron generation.

Patients undergoing shoulder arthroplasty for failed nonoperative treatment of proximal humerus fracture have low implant survival and low patient-reported outcomes: 837 cases from the Danish Shoulder Arthroplasty Registry

Acta Orthopaedica, 2020
Background and purpose — When nonoperative treatment of proximal humerus fracture (PHF) fails, shoulder arthroplasty may be indicated. We investigated risk factors for revision and evaluated patient-reported outcome 1 year after treatment with either ...
