Improved accuracy is one of the vital innovations in designing biopolymer-based products that are gaining momentum in diverse biomedicine arenas. The innovative devices were developed utilizing synthetic polymers but now are replaced with 'green polymer' such as chitosan. These bioactive polymer-based products can control release therapeutics, even greatly minimize the post-surgery inflammations, immune responses, and are biodegradable. Past decade to date, numerous proprietary technologies have been developed and protected by numerous patents. Therefore, strategical analysis of these chitosan-based process or product patent helps to identify key innovative technologies, clinically implementation, and key manufacturers behind these biomedical products. The present article analyzed the trends in patent portfolios of chitosan-based biomedical products and the number of original research papers published over a decade. A spotlight on different marketed grades, modifications for their special use, blend composites, safety profile, and regulatory concerns of chitosan use in bioengineering are covered. A scientific prospection was performed between 2009 and 2020 using the PubMed database. For technological prospection, Lens (free, open patent, and scholarly search) portal was utilized. Chitosan-originated patents were analyzed using cooperative and international patent classifications, covering their citations by patent count. Various chitosan-based patents that are approved and commercial chitosan based biomedical products are even listed. A preliminary perusal of chitosan alone or based patent portfolios can greatly benefit various stakeholders like scientists and corporate firms for new product development, government agencies for allocation of federal funds shaping up biomedicine advances by utilizing chitosan. The present analysis indicates the overall progression and unexplored corners of chitosan in a current global biomedical proposition.

Tabular data, spreadsheets organized in rows and columns, are ubiquitous across scientific fields, from biomedicine to particle physics to economics and climate science. The fundamental prediction task of filling in missing values of a label column based on the rest of the columns is essential for various applications as diverse as biomedical risk models, drug discovery and materials science. Although deep learning has revolutionized learning from raw data and led to numerous high-profile success stories, gradient-boosted decision trees have dominated tabular data for the past 20 years.

The abnormal deposition of amyloid β (Aβ), produced by proteolytic cleavage events of amyloid precursor protein involving the protease γ-secretase and subsequent polymerization into amyloid plaques, plays a key role in the neuropathology of Alzheimer's disease (AD). Here we show that ErbB3 binding protein 1 (EBP1)/proliferation-associated 2G4 (PA2G4) interacts with presenilin, a catalytic subunit of γ-secretase, inhibiting Aβ production. Mice lacking forebrain Ebp1/Pa2g4 recapitulate the representative phenotypes of late-onset sporadic AD, displaying an age-dependent increase in Aβ deposition, amyloid plaques and cognitive dysfunction.

Attention-deficit/hyperactivity disorder (ADHD) presents with symptoms like impulsiveness, inattention, and hyperactivity, often affecting children's academic and social functioning. Non-pharmacological interventions, such as digital cognitive therapy, are emerging as complementary treatments for ADHD. The randomized controlled trial explored the impact of an AI-driven digital cognitive program on impulsiveness, inattentiveness, and neurophysiological markers in 41 children aged 8-12 with ADHD.

The development of the human neocortex is highly dynamic, involving complex cellular trajectories controlled by gene regulation. Here we collected paired single-nucleus chromatin accessibility and transcriptome data from 38 human neocortical samples encompassing both the prefrontal cortex and the primary visual cortex. These samples span five main developmental stages, ranging from the first trimester to adolescence.

Background: Chronic liver disease (CLD) is a substantial cause of morbidity and mortality worldwide. Liver stiffness, as measured by MR elastography (MRE), is well-accepted as a surrogate marker of liver fibrosis.
Purpose: To develop and validate deep learning (DL) models for predicting MRE-derived liver stiffness using routine clinical non-contrast abdominal T1-weighted (T1w) and T2-weighted (T2w) data from multiple institutions/system manufacturers in pediatric and adult patients.
