Recent functionality developments of carboxymethyl chitosan as an active food packaging film material.

In recent years, environmental concerns regarding the persistence of petroleum-based plastic food packaging have increased, prompting the exploration of biopolymer alternatives. Carboxymethyl chitosan (CMCS), a derivative of chitosan, exhibits superior water-soluble film properties, making it an ideal material for degradable food packaging applications. This study comprehensively examines the synthesis methods and properties of CMCS, with a particular emphasis on recent advancements in CMCS-based food packaging films.

Sustained benefit of zanubrutinib vs ibrutinib in patients with R/R CLL/SLL: final comparative analysis of ALPINE.

The ALPINE trial established the superiority of zanubrutinib over ibrutinib in patients with relapsed/refractory chronic lymphocytic leukemia and small lymphocytic lymphoma; here, we present data from the final comparative analysis with extended follow-up. Overall, 652 patients received zanubrutinib (n = 327) or ibrutinib (n = 325). At an overall median follow-up of 42.

Innate immune cell activation by adjuvant AS01 in human lymph node explants is age independent.

Vaccine adjuvants are thought to work by stimulating innate immunity in the draining lymph node (LN), although this has not been proven in humans. To bridge the data obtained in animals to humans, we have developed an in situ human LN explant model to investigate how adjuvants initiate immunity. Slices of explanted LNs were exposed to vaccine adjuvants and revealed responses that were not detectable in LN cell suspensions.

Blood pressure, brain lesions and cognitive decline in patients with atrial fibrillation.

Background: The influence of atrial fibrillation (AF) and blood pressure (BP) on brain lesions and cognitive function is unclear. We aimed to investigate the association of BP with different types of brain lesions and cognitive decline in patients with AF.

Methods: Overall, 1,213 AF patients underwent standardized brain magnetic resonance imaging at baseline and after 2 years, as well as yearly neurocognitive testing.

Exploration of isatin-based inhibitors of SARS-CoV-2 Nsp15 endoribonuclease.

The global health crisis caused by Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) urges the development of new antiviral agents with broad coronavirus coverage. Due to its key role in viral evasion from the host innate immune response, the coronavirus Nsp15 uridine-specific endoribonuclease (EndoU) is of high interest as a drug target. Considering that the isatin scaffold is well-known for its versatile pharmacological properties, we synthesized and evaluated a series of compounds carrying an isatin core.

Does the risk of hypersensitivity reactions to iopromide differ by sex, race, or across regions/countries? An analysis of 152 233 patients from 4 observational studies and the company's pharmacovigilance database.

Objective: To analyse the potential impact of patients' sex, race, and region/country on the risk of hypersensitivity reactions after intra-venous or intra-arterial administration of iopromide.

Methods: Two analyses were performed. (1) The "Phase-IV-Analysis" evaluated an integrated pooled database of 4 non-interventional studies.

Targeting IspD in the Methyl-d-erythritol Phosphate Pathway: Urea-Based Compounds with Nanomolar Potency on Target and Low-Micromolar Whole-Cell Activity.

The methyl-d-erythritol phosphate (MEP) pathway has emerged as an interesting target in the fight against antimicrobial resistance. The pathway is essential in many human pathogens, including (), but is absent in human cells. In the present study, we report on the discovery of a new chemical class targeting IspD, the third enzyme in the pathway.

Twenty years of microplastic pollution research-what have we learned?

Twenty years after the first publication that used the term microplastic, we review current understanding, refine definitions, and consider future prospects. Microplastics arise from multiple sources, including tires, textiles, cosmetics, paint, and the fragmentation of larger items. They are widely distributed throughout the natural environment, with evidence of harm at multiple levels of biological organization.

Gender Disparities in Statin Prescriptions in People With HIV With Low/Moderate to High Cardiovascular Risk.

The REPRIEVE trial suggests that primary cardiovascular disease (CVD) prevention could be considered among people with HIV at low CVD risk. We found cisgender women with low/moderate and high CVD risk are less likely to receive statins than cisgender men. Efforts are needed to guarantee equal access to statin-based CVD prevention.

The cellular prion protein does not affect tau seeding and spreading of sarkosyl-insoluble fractions from Alzheimer's disease.

The cellular prion protein (PrP) plays many roles in the developing and adult brain. In addition, PrP binds to several amyloids in oligomeric and prefibrillar forms and may act as a putative receptor of abnormal misfolded protein species. The role of PrP in tau seeding and spreading is not known.

Final, 10-Year Outcomes with Nivolumab plus Ipilimumab in Advanced Melanoma.

Background: Previous results from this trial showed longer overall survival after treatment with nivolumab plus ipilimumab or with nivolumab monotherapy than with ipilimumab monotherapy in patients with advanced melanoma. Given that patients with advanced melanoma are living longer than 7.5 years, longer-term data were needed to address new clinically relevant questions.

Enzymatic synthesis of -adenosyl-l-homocysteine and its nucleoside analogs from racemic homocysteine thiolactone.

-Adenosyl methionine (SAM)-dependent methyltransferases hold significant potential as tools for the biocatalytic synthesis of complex molecules due to their ability to methylate or alkylate substrates with high regio-, chemo-, and stereoselectivity. Recent advancements in enzyme-catalyzed -methylation and -alkylation of -adenosyl homocysteine (SAH) using synthetic alkylation agents have expanded the scope of methyltransferases in preparative biocatalysis. This development has transformed SAH from an unwanted byproduct into a crucial - and currently expensive - reagent.

Inhaled colistimethate sodium in patients with bronchiectasis and Pseudomonas aeruginosa infection: results of PROMIS-I and PROMIS-II, two randomised, double-blind, placebo-controlled phase 3 trials assessing safety and efficacy over 12 months.

Background: Chronic lung infection with Pseudomonas aeruginosa is associated with increased exacerbations and mortality in people with bronchiectasis. The PROMIS-I and PROMIS-II trials investigated the efficacy and safety of 12-months of inhaled colistimethate sodium delivered via the I-neb.

Methods: Two randomised, double-blind, placebo-controlled trials of twice per day colistimethate sodium versus placebo were conducted in patients with bronchiectasis with P aeruginosa and a history of at least two exacerbations requiring oral antibiotics or one requiring intravenous antibiotics in the previous year in hospitals in Argentina, Australia, Belgium, Canada, France, Germany, Greece, Israel, Italy, Netherlands, New Zealand, Poland, Portugal, Spain, Switzerland, the UK, and the USA.

Grounding, necessity, and relevance.

(GN) is the view that full grounds necessitate what they ground. Although GN has been rather popular among philosophers, it faces important counterexamples: For instance, A = [Socrates died] fully grounds C = [Xanthippe became a widow]. However, A fails to necessitate C: A have obtained together with B = [Socrates and Xanthippe were never married], without C obtaining.

Characterization of O uncoupling in biodegradation reactions of nitroaromatic contaminants catalyzed by rieske oxygenases.

Rieske oxygenases are known as catalysts that enable the cleavage of aromatic and aliphatic C-H bonds in structurally diverse biomolecules and recalcitrant organic environmental pollutants through substrate oxygenations and oxidative heteroatom dealkylations. Yet, the unproductive O activation, which is concomitant with the release of reactive oxygen species (ROS), is typically not taken into account when characterizing Rieske oxygenase function. Even if considered an undesired side reaction, this O uncoupling allows for studying active site perturbations, enzyme mechanisms, and how enzymes evolve as environmental microorganisms adapt their substrates to alternative carbon and energy sources.
