Spatio ‐Temporal Electrowetting and Reaction Monitoring in Microfluidic Gas Diffusion Electrode Elucidates Mass Transport Limitations
A microfluidic model gas diffusion electrode (GDE) is presented, in which realistic wetting behavior, electrowetting and reaction monitoring are possible. Saturation curves show the wetting behavior, which is comparable to lab-scale GDEs. Oscillating behavior during reactions is observed both regarding the wetting state and the pH value. Mass transport is identified as a major influence on the performance of GDEs. AbstractThe use of gas diffusion electrodes (GDEs) enables efficient electrochemical CO2 reduction and may be a viable technology in CO2 utilization after carbon capture. Understanding the spatio-temporal phenome...

Self ‐Powered Colorful Dynamic Electrowetting Display Systems Based on Triboelectricity
Self-powered colorful dynamic display systems are developed by integrating the nanotube-patterned triboelectric nanogenerator (TENG) with the electrowetting display (EWD). By controlling the electrical output applied to the different pixel layers of the EWD device, the self-powered dynamic multi-color display can be achieved. This work contributes to portable and wearable electronic ink displays, indoor and outdoor sports equipment, and communication devices. AbstractElectrowetting displays (EWDs) based on microfluidics are highly sought after in the fields of electronic devices, smart homes, and information communication....

Build a High-Performance All-Solid-State Lithium Battery through Introducing Competitive Coordination Induction Effect in Polymer-Based Electrolyte
Angew Chem Int Ed Engl. 2024 Feb 22:e202400960. doi: 10.1002/anie.202400960. Online ahead of print.ABSTRACTPolymer-inorganic composite electrolytes (PICE) have attracted tremendous attention in all-solid-state lithium batteries (ASSLBs) due to facile processability. However, the poor Li+ conductivity at room temperature (RT) and interfacial instability severely hamper the practical application. Herein, we propose a concept of competitive coordination induction effects (CCIE) and reveal the essential correlation between the local coordination structure and the interfacial chemistry in PEO-based PICE. CCIE introduction great...

Molecules, Vol. 29, Pages 970: Formulation Optimization and Performance Prediction of Red Mud Particle Adsorbents Based on Neural Networks
This study aimed to identify the best formula for an RM adsorbent using a mathematical model that examines the relationship between 11 formulation types (e.g., pore-assisting agent, component modifier, and external binder) and 9 properties (e.g., specific surface area, wetting angle, and Zeta potential). This model was built using a back-propagation neural network (BP) based on single-factor experimental data and orthogonal experimental data. The model trained and predicted the established network structure to obtain the optimal adsorbent formula. The RM particle adsorbents had a pH of 10.16, specific surface area (BET) of...

Case report: Peri-procedural hydroxyurea helps minimize bleeding in patients with Essential Thrombocythemia associated with acquired von Willebrand syndrome
CONCLUSION: Patients with extreme thrombocytosis are at high risk of bleeding due to acquired Von Willebrand Syndrome. Initiation of hydroxyurea at the time of bone marrow exam helps to control platelet count and minimizes the risk of peri-procedural hemorrhage in high-risk Essential Thrombocythemia patients with suspected acquired Von Willebrand Syndrome.PMID:38361779 | PMC:PMC10867169 | DOI:10.3389/fonc.2024.1326209 (Source: Cancer Control)

Desmopressin, Misoprostol, nor Carboprost Affect Platelet Aggregability Following Traumatic Brain Injury and Aspirin
Desmopressin (DDAVP) has been utilized clinically in patients taking aspirin (ASA) to improve drug-induced platelet dysfunction. Misoprostol and carboprost, prostaglandin analogs commonly used for postpartum hemorrhage, may also induce platelet aggregation. The aim of this study was to determine the effects of DDAVP, misoprostol, and carboprost administration on platelet aggregability following traumatic brain injury (TBI) in mice treated with ASA.

Wettability of Different Zirconia Implant Surfaces after Glycine and Erythritol Treatment
CONCLUSIONS: The initial wettability of zirconia disks differs between manufacturers, and air-polishing with erythritol powder increases the wettability of zirconia implant disks for saline, bovine serum, bovine thrombin, and bovine artificial blood.PMID:38350114 | DOI:10.11607/jomi.10862 (Source: International Journal of Oral and Maxillofacial Implants)

Case report: Complete restoration of the HPA axis function in Cushing ’s disease with drug treatment
This report describes a rare case of a 20-year-old man with an ACTH- and prolactin-secreting invasive pituitary macroadenoma causing hyperprolactinemia and Cushing’s disease. He was later found to have an AIP mutation. Treatment with cabergoline (1.5 mg weekly) normalized prolactin concentrations and induced a major shrinkage of the adenoma. Not only was urinary free cortisol normalized for more than 14 years, but also the treatment induced normal hypothalamo-pituitary-adrenal (HPA) axis function as illustrated by the reappearance of a normal cortisol/ACTH circadian rhythm, cortisol suppression to dexamethasone, and disa...

Progress in von Willebrand Disease Treatment: Evolution towards Newer Therapies
Semin Thromb Hemost DOI: 10.1055/s-0044-1779485von Willebrand disease (VWD) is a very heterogenous disease, resulting in different phenotypes and different degrees of bleeding severity. Established therapies (i.e., desmopressin, antifibrinolytic agents, hormone therapy for heavy menstrual bleeding, and von Willebrand factor [VWF] concentrates) may work in some subtypes, but not in all patients. In recent years, progress has been made in improving the diagnosis of VWD subtypes, allowing for more specific therapy. The impact of VWD on women's daily lives has also come to the fore in recent years, with hormone therapy, tranex...

Use and Outcomes of Botulinum Toxin A for Both Neurogenic and Non-neurogenic Voiding Dysfunction in the Pediatric Patient
AbstractPurpose of ReviewIn this review, we seek to present the most recent data that is available and not perform an exhaustive review of the whole literature. Many recent publications have provided us with randomized prospective studies which confirmed much of the prior groundbreaking work done by the authors who published some of the original work in the field. In some cases, we may intersperse data from an adult study when there is a lack of data from a pediatric study.Recent FindingsIn a 48-week prospective, multicenter, randomized, double-blind study in children (aged 5 –17 years) with neurogenic detrusor overact...

Diabetes insipidus: vasopressin deficiency …
Ann Endocrinol (Paris). 2024 Feb 3:S0003-4266(24)00011-8. doi: 10.1016/j.ando.2023.11.006. Online ahead of print.ABSTRACTDiabetes insipidus is a disorder characterized by hypo-osmotic polyuria secondary to abnormal synthesis, regulation, or renal action of antidiuretic hormone. Recently, an expert group, with the support of patient associations, proposed that diabetes insipidus be renamed to avoid confusion with diabetes mellitus. The most common form of diabetes insipidus is secondary to a dysfunction in the neurohypophysis (central diabetes insipidus) and would be therefore termed 'vasopressin deficiency'. The rarer form...

A machine learning approach for predicting treatment response of hyponatremia
Endocr J. 2024 Feb 2. doi: 10.1507/endocrj.EJ23-0561. Online ahead of print.ABSTRACTHyponatremia leads to severe central nervous system disorders and requires immediate treatment in some cases. However, a rapid increase in serum sodium (s-Na) concentration could cause osmotic demyelination syndrome. To achieve a safety hyponatremia treatment, we develop a prediction model of s-Na concentration using a machine learning. Among the 341 and 47 patients admitted to two tertiary hospitals for hyponatremia treatment (s-Na <130 mEq/L), those who were admitted to the general unit with urine sodium <20 mEq/L or treated with de...
