A Simplified Model of Adenine-Induced Chronic Kidney Disease Using SKH1 Mice.

Commonly used adenine-induced chronic kidney disease (CKD) murine models often employ C57BL/6 mice; however, this strain has inherent limitations due to its natural resistance to developing key pathological features of CKD, such as tubulointerstitial fibrosis and inflammation. There have been attempts to overcome these barriers by using multiple concentrations of adenine-supplemented diets or by performing prolonged experiments up to 20 weeks. Here, we demonstrate that SKH1 Elite mice develop clinically relevant CKD phenotypes (e.

Position statement on the diagnosis and management of acute leukaemia and aggressive lymphomas in pregnancy.

Haematological malignancies affect 12·5 in 100 000 pregnancies. Over the past two decades, the number of haematological malignancies in pregnancy has substantially increased. Life-threatening haematological malignancies in pregnancy, such as acute leukaemia and aggressive lymphomas, pose a unique therapeutic challenge: clinicians must consider both maternal and fetal wellbeing, aiming to deliver optimal curative therapy for the patient and a successful pregnancy outcome.

Acetaminophen in Pregnancy and Attention-Deficit and Hyperactivity Disorder and Autistic Spectrum Disorder.

Acetaminophen is a common over-the-counter medication that recently gained substantial media attention regarding its use by pregnant individuals. In this clinical perspective, we discuss the strengths and limitations of the published literature on the effect of maternal acetaminophen use in pregnancy on the child's risk of developing attention-deficit and hyperactivity disorder (ADHD) and autistic spectrum disorder (ASD). Studies included were specifically selected on the basis of the quality and validity of ADHD or ASD outcome definitions.

Establishing construct validity for dynamic measures of behavior using naturalistic study designs.

There has been a recent surge of naturalistic methodology to assess complex topics in psychology and neuroscience. Such methods are lauded for their increased ecological validity, aiming to bridge a gap between highly controlled experimental design and purely observational studies. However, these measures present challenges in establishing construct validity.

Hydridostannylene Derivatives of Magnesium and Calcium.

Reactions of a m-terphenylhydridostannylene with β-diketiminato magnesium and calcium hydrides provide bis-μ-hydrido species, the heterobimetallic constitutions of which are maintained after the addition of THF donor solvent. In both cases, reactions with hex-1-ene result in the formation of tetravalent organostannyl alkaline earth derivatives. Whereas the magnesium reagent undergoes facile twofold addition, the calcium-centered process is arrested after a single alkene reduction event.

Nucleophilic Triphenylgermanides of Magnesium and Calcium.

The dimeric calcium and magnesium hydrides, [(BDI)AeH] [BDI=HC{(Me)CNDipp}, Dipp=2,6-i-PrCH; Ae=Mg or Ca] do not react with PhGeH in non-coordinating solvent. Addition of THF, however, induces deprotonation and access to monomeric Ae-germanide complexes, [(BDI)Ae{GePh}(THF)], both of which have been structurally characterized. Although this process is facile when Ae=Ca, the analogous magnesium-based reaction requires heating to temperatures >100 °C, under which conditions germanide formation is complicated by THF ring opening and the generation of an alkaline earth germyl-C-terminated n-butoxide, [(BDI)Mg{μ-O(CH)GePh}].

Using a computational cognitive model to simulate the effects of personal and social network experiences on seasonal influenza vaccination decisions.

Introduction: Seasonal influenza poses significant societal costs, including illness, mortality, and reduced work productivity. Vaccination remains the most effective strategy for preventing the disease, yet vaccination rates in the United States fall below 50% for adults. Understanding the factors influencing vaccination decisions is crucial for designing interventions to improve uptake.

Aerosolized Harmful Algal Bloom Toxin Microcystin-LR Induces Type 1/Type 17 Inflammation of Murine Airways.

Harmful algal blooms are increasing globally and pose serious health concerns releasing cyanotoxins. Microcystin-LR (MC-LR), one of the most frequently produced cyanotoxins, has recently been detected in aerosols generated by the normal motions of affected bodies of water. MC-LR aerosol exposure has been linked to a pro-inflammatory influence on the airways of mice; however, little is understood about the underlying mechanism or the potential consequences.

Phosphorylation of HP1/Swi6 relieves competition with Suv39/Clr4 on nucleosomes and enables H3K9 trimethyl spreading.

Heterochromatin formation in Schizosaccharomyces pombe requires the spreading of histone 3 (H3) Lysine 9 (K9) methylation (me) from nucleation centers by the H3K9 methylase, Suv39/Clr4, and the reader protein, HP1/Swi6. To accomplish this, Suv39/Clr4 and HP1/Swi6 have to associate with nucleosomes both nonspecifically, binding DNA and octamer surfaces and specifically, via recognition of methylated H3K9 by their respective chromodomains. However, how both proteins avoid competition for the same nucleosomes in this process is unclear.

Nano-bio interactions of Gum Arabic-stabilized lanthanide-based upconverting nanoparticles: and study.

Lanthanide-based nanoparticles (Ln-NPs) are highly valued for their unique optical and magnetic properties, making them useful in various scientific fields, including materials science and biomedicine. This study investigated the use of Gum Arabic (GA), a natural, non-toxic biopolymer, as capping agent for Ln-NPs to enhance their biocompatibility and chemical and colloidal stability. Specifically, Er/Yb co-doped NaGdF Ln-NPs were modified with GA, followed by their characterization with respect to upconversion properties and as well as toxicity.

Synthesis of a Truncated Microcystin Tetrapeptide Molecule from a Partial Mcy Gene Cluster in Microcystis Cultures and Blooms.

spp. threaten freshwater ecosystems through the proliferation of cyanobacterial harmful algal blooms (cyanoHABs) and production of the hepatotoxin, microcystin. While microcystin and its biosynthesis pathway, encoded by the genes, have been well studied for over 50 years, a recent study found that populations in western Lake Erie contain a transcriptionally active partial operon, in which the A2 domain of and are present but the genes are absent.

Common Cold Coronavirus 229E Induces Higher Interferon Stimulating Gene Responses in Human Nasal Epithelial Cells from Patients with Chronic Rhinosinusitis with Polyposis.

Background: Viral infections have long been implicated in the development of chronic rhinosinusitis with nasal polyps (CRSwNP). Given widespread exposure to the common cold coronavirus 229E (HCoV229E), we sought to investigate how HCoV-229E is cleared and stimulates interferon pathways in air-liquid interface (ALI) cultures from patients with CRSwNP.

Objective: The objective of this study was to identify whether viral clearance and ISG expression is different in ALI cultures from donors with CRSwNP compared with controls.
