Optimization and Characterization of Aspirin‐ and Ibuprofen‐Loaded Lipid‐Based Nanoparticle Synthesis for Antibacterial Activity and Cytotoxic Effect

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Lipid‐based nanoparticles (LNPs) are favored for drug delivery because of their low toxicity, high biocompatibility, ability to self‐assemble into nanoparticles, and ability to enhance drug bioavailability, thereby improving drug release modulation and pharmacokinetics.

Magnetic Field‐Modulated Boolean Logic in Proteinoid‐ Fe3 O4 Hybrid Materials

open access: yesAdvanced Physics Research, EarlyView.
Proteinoid‐Fe3O4${\rm Fe}_3{\rm O}_4$. nanoparticle composites exhibit spontaneous electrical oscillations that emulate Boolean logic gates (AND, OR, XOR, NAND, NOR, NOT) under magnetic field modulation. External fields of 65.103 mT tune oscillatory behavior: 84 mT enhances amplitude while 103 mT suppresses it.

The morphology of the oval window in Paranthropus robustus compared to humans and other modern primates

open access: yesThe Anatomical Record, EarlyView.
Abstract The oval window (OW) is an opening connecting the inner and middle ear. Its area has been shown to consistently scale with body mass (BM) in primates, and has been used alongside semi‐circular canal (SCC) size to differentiate Homo sapiens and fossil hominins, including Paranthropus robustus.

Are there morpho‐acoustic patterns of adaptation in nonhuman primate ears? Testing the role of ecology and habitat in shaping ear morphology and function

open access: yesThe Anatomical Record, EarlyView.
Abstract Analysis of the variation in the bony structures of the inner and middle ear provides critical insights into functional morphology, as well as adaptive morphology across primates. In this study, we investigated whether ear morphology patterns are related to the ecological characteristics of species and their habitats to test two acoustic ...

New techniques for old bones: Morphometric and diffeomorphometric analysis of the bony labyrinth of the Reilingen and Ehringsdorf Neandertals

open access: yesThe Anatomical Record, EarlyView.
Abstract Neandertals are known to possess very distinctive traits in their bony labyrinth morphology, such as an inferiorly positioned posterior canal and a very low number of turns in the cochlea. Hence, the inner ear has been often used to assess the Neandertal status of fragmentary fossils.

Three‐dimensional geometric morphometric analysis of diaphragmatic dome motion in COPD patients

open access: yesThe Anatomical Record, EarlyView.
Abstract Diaphragmatic dysfunction is a hallmark of chronic obstructive pulmonary disease (COPD), especially in emphysema, where hyperinflation alters diaphragm geometry and impairs inspiratory mechanics. However, quantitative three‐dimensional (3D) assessments of diaphragmatic dome shape and motion across COPD phenotypes are limited.

Cytokine Pathways Driving Diverse Tissue Pathologies in Rheumatoid Arthritis

open access: yesArthritis &Rheumatology, EarlyView.
Rheumatoid arthritis (RA) is a complex systemic disorder characterized primarily by articular inflammation and destruction with associated functional loss and reduced quality of life. RA is also associated with extra‐articular disease, such as that of the lung, with potentially devastating clinical consequences. The critical importance of comorbidities,
