Genetic insights and therapeutic avenues: unraveling the role of polyunsaturated fatty acids as mediators between hypothyroidism and Von Willebrand disease through Mendelian randomization.

Background: Previous observational studies have shown that Hypothyroidism is associated with Von Willebrand Disease (VWD), but the causal relationship has not been confirmed because of conflicting findings and confounding by mixing factors. There are also some studies suggesting that polyunsaturated fatty acids (PUFA) may be one of the potential mediators. In this study, we used a Mendelian randomization study to analyze the causal relationship between Hypothyroidism and VWD and to investigate whether polyunsaturated fatty acids mediate the effects of Hypothyroidism on VWD.

Methods: This study included 180 ADSA and 188 AD patients without sarcopenia (ADNSA), and evaluated demographics, cognitive function, motor capacity, emotional state, and daily living abilities.

Multiscale interstitial fluid computation modeling of cortical bone to characterize the hydromechanical stimulation of lacunar-canalicular network.

Bone tissue is a biological composite material with a complex hierarchical structure that could continuously adjust its internal structure to adapt to the alterations in the external load environment. The fluid flow within bone is the main route of osteocyte metabolism, and the pore pressure as well as the fluid shear stress generated by it are important mechanical stimuli perceived by osteocytes. Owing to the irregular multiscale structure of bone tissue, the fluid stimulation that lacunar-canalicular network (LCN) in different regions of the tissue underwent remained unclear.

Effect of peripheral blood absolute monocyte count at admission on relapse-free survival in patients with idiopathic thrombotic thrombocytopenic purpura in remission.

Introduction: Peripheral monocytes have been reported to correlate with clinical outcomes in various types of malignancies. Previous reports have also shown that acute-phase thrombotic thrombocytopenic purpura (TTP) plasma could induce the activation of monocytes. However, the significance of peripheral blood absolute monocyte count (AMC) in idiopathic TTP remains an unanswered question.

Ultra-strong and solvent-resistant lignin-based non-isocyanate polyurethane adhesives: One-pot strategy toward versatile bonding.

Isocyanate-free polyurethane adhesives have attracted considerable attention as a promising environmentally friendly alternative. However, their progress has been hindered by insufficient bonding performance and weak solvent resistance, as well as the laborious synthesis processes involved. Herein, we successfully synthesized a high-performance lignin-based non-isocyanate adhesives (LNIPUs-G) through a one-pot strategy that combines the polycondensation of carbonate groups with polyether amines and aldehyde-amine chemistry.

Engineered Mesenchymal Stem Cell-Derived Extracellular Vesicles Scavenge Self-Antigens for Psoriasis Therapy via Modulating Metabolic and Immunological Disorders.

Psoriasis is a chronic inflammatory dermatosis driven by excessive activation of the immune system. Recent studies have demonstrated the therapeutic potential of mesenchymal stem cell-derived extracellular vesicles (MSC-EVs) to psoriasis because of their immunomodulation functions. Yet, the outcome of MSC-EVs alone is still unsatisfactory and the underlying mechanisms are also unclear.

A new species in the Cyrtodactylus intermedius (Squamata: Gekkonidae) group from an isolated limestone karst formation in southwestern Cambodia.

The gekkonid lizard Cyrtodactylus intermedius was formerly considered to be a single widespread species in hilly areas across eastern Thailand through southern Vietnam but has recently been partitioned into a complex of 12 nominal species across its range. A population belonging to the C. intermedius group was recently found in an isolated limestone karst block in Kampot Province in southwestern Cambodia, part of which lies within the recently designated Phnom Preah Kuhear Loung Natural Heritage Site.

Parabens are widely used as preservatives in personal care products and are linked to potential disruptions in placental steroidogenesis. However, their exact impact remains unclear. This study aimed to explore the inhibition, mechanisms, structure-activity relationships (SAR) of parabens on human placental 3β-hydroxysteroid dehydrogenase type 1 (h3β-HSD1) and its rat counterpart, r3β-HSD4.

Identification and analysis of microplastic aggregation in CAR-T cells.

Microplastics (MPs) are increasingly recognized as contaminants present in various environments and are widely acknowledged as potential hazards to the mammalian immune system. In our study of chimeric antigen receptor T cell (CAR-T) therapy, we observed the presence of MP in CAR-T cell products for the first time. It is worth exploring whether MP could enter CAR-T cells and how they might affect CAR-T cells' functionality.

Programmable and flexible wood-based origami electronics.

Natural polymer substrates are gaining attention as substitutes for plastic substrates in electronics, aiming to combine high performance, intricate shape deformation, and environmental sustainability. Herein, natural wood veneer is converted into a transparent wood film (TWF) substrate. The combination of 3D printing and origami technique is established to create programmable wood-based origami electronics, which exhibit superior flexibility with high tensile strength (393 MPa) due to the highly aligned cellulose fibers and the formation of numerous intermolecular hydrogen bonds between them.

Fragmentomics of plasma mitochondrial and nuclear DNA inform prognosis in COVID-19 patients with critical symptoms.

Background: The mortality rate of COVID-19 patients with critical symptoms is reported to be 40.5%. Early identification of patients with poor progression in the critical cohort is essential to timely clinical intervention and reduction of mortality.

Double-crosslinked polyvinyl alcohol/starch bioplastic with superior water-resistance and flame retardancy.

The high water solubility and flammability of polyvinyl alcohol (PVA) limits its further widespread use in areas such as bioplastic and green packaging. In this study, double-crosslinked polyvinyl alcohol/starch bioplastics (named PDA) were fabricated using PVA, dialdehyde starch (DAS), and phytic acid (PA), resulting in a material with superior water resistance, flame retardancy, and excellent degradability. PA not only plays the role of catalyst for the chemical crosslinking but also as the physical crosslinker to form the intermolecular hydrogen bonds with PVA and DAS.

Diagnostic value and correlation analysis of serum cytokine levels in patients with multiple system atrophy.

Background: The association between cytokines in peripheral blood and clinical symptoms of multiple system atrophy (MSA) has been explored in only a few studies with small sample size, and the results were obviously controversial. Otherwise, no studies have explored the diagnostic value of serum cytokines in MSA.

Methods: Serum cytokines, including interleukin-6 (IL-6), interleukin-8 (IL-8), and tumor necrosis factor alpha (TNF-α), were measured in 125 MSA patients and 98 healthy controls (HCs).

Obesity influencing circulating levels of nutrients: Evidence from Mendelian randomization study.

Observational studies have established that obesity is associated with nutritional deficiencies, but the exact causality remains uncertain. Thus, this Mendelian randomization (MR) study aimed to identify the causal associations between obesity and circulating levels of nutrients. Single-nucleotide polymorphisms associated with obesity (body mass index and waist-hip ratio), were extracted from a genome-wide association study of 694,649 European ancestry.

Comparison of spontaneous brain activity in distinguishing parkinsonian variant of multiple system atrophy from Parkinson's disease at an early stage.

Background: The overlapping clinical manifestations in parkinsonian variant of multiple system atrophy (MSA-P) and Parkinson's Disease (PD) can complicate clinical diagnostic accuracy, particularly in the early stage. The study aims to uncover the patterns of brain function in the initial phase of the two conditions.

Methods: We recruited 24 MSA-P patients, 34 PD patients and 27 healthy controls (HC).

Multidose transient transfection of human embryonic kidney 293 cells modulates recombinant adeno-associated virus2/5 Rep protein expression and influences the enrichment fraction of filled capsids.

Recombinant adeno-associated virus (rAAV) is a commonly used in vivo gene therapy vector because of its nonpathogenicity, long-term transgene expression, broad tropism, and ability to transduce both dividing and nondividing cells. However, rAAV vector production via transient transfection of mammalian cells typically yields a low fraction of filled-to-total capsids (~1%-30% of total capsids produced). Analysis of our previously developed mechanistic model for rAAV2/5 production attributed these low fill fractions to a poorly coordinated timeline between capsid synthesis and viral DNA replication and the repression of later phase capsid formation by Rep proteins.

Bilateral facial nerve palsy complicating Kawasaki disease: A case report and literature review.

Rationale: Kawasaki disease (KD) manifests as an acute, self-limited vasculitis disease that constitutes the primary cause of acquired heart disease in children under 5 years of age. Facial nerve palsy (FNP) is a rare complication associated with coronary artery lesions (CALs) in patients with KD. Patients with KD and FNP usually present atypically, leading to a delayed diagnosis and treatment of KD.
