Exploration of the impact of different drying methods on the quality of Gastrodia elata: A study based on drying kinetics and multidimensional quality evaluation.

In this study, the drying kinetics and multidimensional quality of Gastrodia elata (GE) obtained through five different drying methods were analyzed. The Page model provided the best fit. Though widely used, hot-air drying (HA-D) showed mediocre performance.

Comprehensive Evaluation of the Genetic Basis of Keratoconus: New Perspectives for Clinical Translation.

Purpose: Keratoconus (KC) is a corneal disorder with complex etiology, apparently involving both genetic and environmental factors, characterized by progressive thinning and protrusion of the cornea. We aimed to identify novel genetic regions associated with KC susceptibility, elucidate relevant genes for disease development, and explore the translational implications for therapeutic intervention and risk assessment.

Methods: We conducted a genome-wide association study (GWAS) that integrated previously published data with newly generated genotyping data from an independent European cohort.

Fabrication of injectable, adhesive, self-healing, superabsorbent hydrogels based on quaternary ammonium chitosan and oxidized pullulan.

Injectable hydrogels, which are polymeric materials that are characterized by their ability to be injected in a liquid form into cavities and subsequently undergo in situ solidification, have garnered significant attention. These materials are extensively used in a range of biomedical applications. This study synthesized several injectable composite hydrogels through the mild Schiff base reaction while imposing different concentrations of quaternary ammonium chitosan and oxidized pullulan.

Ice thickness control and measurement in the VitroJet for time-efficient single particle structure determination.

Embedding biomolecules in vitreous ice of optimal thickness is critical for structure determination by cryo-electron microscopy. Ice thickness assessment and selection of suitable holes for data collection are currently part of time-consuming preparatory routines performed on expensive electron microscopes. To address this challenge, a routine has been developed to measure ice thickness during sample preparation using an optical camera integrated in the VitroJet.

Phosphatidylserine-blocking nanoparticles inhibit thrombosis without increased bleeding in mice.

Background: Phosphatidylserine (PS) is a procoagulant phospholipid enriched on surfaces of activated vascular cells including platelets, endothelium, monocytes, and microvesicles. As a molecular driver of thrombosis accessible to drug blockade, PS is an attractive pharmacologic target for modulating thrombogenesis, with potentially reduced bleeding risk compared to anticoagulant and antiplatelet therapies.

Objectives: Test antithrombotic capabilities of a liposomal formulation, Zn-dipicolylamine cyanine-3[22,22]/1-palmitoyl-2-oleoyl-sn-glycero-3-phosphocholine (molar ratio, 3:97), designated as DPAL, which we previously described binds selectively to PS-enriched cell surfaces, compared with effects on bleeding, in mouse models.

Technology for helping people with neuromotor, intellectual, and speech disabilities engage in leisure and communication activities: a proof-of-concept study.

We extended the assessment of our recently developed technology to help people with neuromotor, intellectual, and speech disabilities access (listen to) music, communicate with distant partners, and answer questions. The technology included a tablet (1) fitted with an Internet connection, a SIM card, WhatsApp Messenger, and MacroDroid application, and (2) interfaced with different pairs of response sensors. Six participants were included in the study, which was carried out according to a nonconcurrent multiple baseline design across participants.

Application of 2D Extension of Hjorth's Descriptors to Distinguish Defined Groups of Bee Pollen Images.

Adulteration of food products is a serious problem in the current economy. Honey has become the third most counterfeit food product in the world and requires effective authentication methods. This article presents a new approach to the differentiation of bee pollen, which can support the development of a methodology to test honey quality based on the analysis of bee pollen.

Effects of 12-Week Supplementation with Coffee Diterpene Cafestol in Healthy Subjects with Increased Waist Circumference: A Randomized, Placebo-Controlled Trial.

: Coffee consumption is inversely associated with type 2 diabetes. Cafestol, a bioactive compound in coffee, has demonstrated glucose-lowering and insulin-secretory properties in cell and animal studies. The acute effects of cafestol on glucose metabolism in humans have only been briefly investigated, and longer-term effects have not been explored.

Eco-Friendly Carbon Nanotubes Reinforced with Sodium Alginate/Polyacrylic Acid for Enhanced Adsorption of Copper Ions: Kinetics, Isotherm, and Mechanism Adsorption Studies.

This study investigates the removal efficiency of Cu from wastewater using a composite hydrogel made of carbon nanotubes (CNTs), sodium alginate (SA), and polyacrylic acid (PAA) prepared by free radical polymerization. The CNTs@SA/PAA hydrogel's structure and properties were characterized using SEM, TEM, FTIR, XRD, rheology, DSC, EDS, elemental mapping analysis, and swelling. The adsorption performance for Cu was tested in batch adsorption experiments, considering the pH, dosage, initial concentration, and contact time.

Discriminative Power of the Flow through Cell Dissolution Tester in Predicting the In Vivo Performance of Pentoxifylline SR Product under Fed and Fasting Conditions.

This study explored, for the first time the role of different designs of the Flow-Through-Cell (FTC, USP IV) dissolution Tester in predicting the in-vivo performance of Pentoxifylline (PTX) sustained-release (SR) market product, under fed & fasting conditions. Release studies of Trental SR 400 mg (Sanofi, Egypt), were carried-out in the FTC under different conditions, including: different volumes / compositions of release media, variable FTC flow patterns as well as applying open / closed loop configuration setups. Pharmacokinetic (PK) data, obtained from literature, were converted to in-vivo fraction-absorbed [F] using Wagner-Nelson (WN) method.

Cost-Utility Analysis of Teledermatology Units in Primary Care Centers Versus Face-to-Face Dermatology Consultations in the Hospital.

Objective: To perform an economic evaluation to determine whether or not teledermatology (TD) units in primary care (PC) centers offer an alternative in terms of cost-utility and cost per quality-adjusted life years (QALYs) to conventional dermatology consultations (face-to-face dermatology [F-F/D]) at the hospital from the perspective of the Public Health System (PHS) and the patients.

Methods: This is a randomized, controlled, nonblinded, and multicenter study. During 6 months, data from 450 patients (TD: 225 vs.

Advances in magnetic resonance imaging for the assessment of paediatric focal epilepsy: a narrative review.

Background And Objective: Epilepsy affects approximately 50 million people worldwide, with 30-40% of patients not responding to medication, necessitating alternative therapies such as surgical intervention. However, the accurate localization of epileptogenic lesions, particularly in pediatric magnetic resonance imaging (MRI)-negative drug-resistant epilepsy, remains a challenge. This paper reviews advanced neuroimaging techniques aimed at improving the detection of such lesions to enhance surgical outcomes.

Insulator-to-Metal Transition and Isotropic Gigantic Magnetoresistance in Layered Magnetic Semiconductors.

Magnetotransport, the response of electrical conduction to external magnetic field, acts as an important tool to reveal fundamental concepts behind exotic phenomena and plays a key role in enabling spintronic applications. Magnetotransport is generally sensitive to magnetic field orientations. In contrast, efficient and isotropic modulation of electronic transport, which is useful in technology applications such as omnidirectional sensing, is rarely seen, especially for pristine crystals.
