Synthesis and its characterisation of selenium/silver/chitosan and cellular toxicity against liver carcinoma cells studies
Nat Prod Res. 2023 Sep 14:1-9. doi: 10.1080/14786419.2023.2256023. Online ahead of print.ABSTRACTLiver cancer is one of the most common lethal malignancy in the world. To treat liver cancer, new cure options are crucial. The use of natural substances along nanosciences may provide healing with lower toxicity and a smaller amount of side properties. In this research, The three-component selenium-silver-chitosan nanocomposite (Se-Ag-CS NCs) were synthesised with the help of ultrasound in a stepwise manner. The as-synthesised Se-Ag-CS NCs were characterised accordingly by applying powder X-Ray diffraction (PXRD), Fourier tran...

J Mech Behav Biomed Mater. 2023 Sep 7;147:106106. doi: 10.1016/j.jmbbm.2023.106106. Online ahead of print.ABSTRACTBioactive scaffolds with polymer and nanostructured bioactive glass-based composites are promising materials for regenerative applications in consequence of close mimics of natural bone composition. Poly methyl methacrylate (PMMA) is a highly preferred thermoplastic polymer for orthopedic applications as it has good biocompatibility. Different kinds of bioactive, biodegradable as well as biocompatible biomaterial composites such as Bioglass (BG), Hydroxyapatite (Hap), and Tricalcium phosphate (TCP) can be integ...

Cerebellar volumes and the intrinsic cerebellar network in patients with obstructive sleep apnea
CONCLUSION: This study established that patients with OSA exhibited decreased total cerebellar volumes and particularly reduced volumes in subdivisions such as the left lobule VIIB compared to healthy controls. These findings suggest potential involvement of the cerebellum in the underlying mechanisms of OSA.PMID:37710027 | DOI:10.1007/s11325-023-02916-y

Molecular characteristics and clinical features of Staphylococcus epidermidis healthcare-associated late-onset bacteremia among infants hospitalized in neonatal intensive care units
CONCLUSIONS: More than 90% of S. epidermidis bloodstream isolates from infants in NICU in Taiwan were resistant to oxacillin. Though diverse, more than 90% of the isolates (episodes) belonged to CC2. No statistically significant differences were found in terms of clinical characteristics among the infants infected with genetically different strains.PMID:37709633 | DOI:10.1016/j.jmii.2023.08.005

Poly(glycidyl methacrylate) modified cellulose nanocrystals and their PBAT-based nanocomposites
In this study, chemical modification of CNC through grafting poly(glycidyl methacrylate) (PGMA) with various degrees was implemented. Wettability of the modified CNCs (mCNCs) were controlled and their structure was characterized through Fourier transform infrared spectroscopy (FTIR), X-ray photoelectron spectroscopy (XPS), optical microscopy, X-ray diffraction (XRD), thermogravimetric analysis (TGA), and differential scanning calorimetry (DSC). The nanocomposites of polybutylene adipate terephthalate (PBAT) with 3 wt% CNC and mCNC were prepared using an internal melt mixer. To differentiate the effects of CNC and PGMA mole...

Effect of the magnetic core in alginate/gum composite on adsorption of divalent copper, cadmium, and lead ions in the aqueous system
Int J Biol Macromol. 2023 Sep 12:126884. doi: 10.1016/j.ijbiomac.2023.126884. Online ahead of print.ABSTRACTThe change of composition of an adsorbent material has been widely used as a method to increase its adsorption capacity, particularly concerning adsorbents made of polysaccharides. Introducing magnetic adsorbents into contaminated water treatment systems is a highly promising strategy, as it promotes the metal ions removal from water. Considering this, gum Arabic (GA) was associated with alginate (Alg), when magnetite nanoparticles were present or absent, to produce beads that were utilised to take up Cu(II), Cd(II),...

Genome-wide survey, molecular evolution and expression analysis of Auxin Response Factor (ARF) gene family indicating their key role in seed number per pod in pigeonpea (C. cajan L. Millsp.)
Int J Biol Macromol. 2023 Sep 12:126833. doi: 10.1016/j.ijbiomac.2023.126833. Online ahead of print.ABSTRACTAuxin Response Factors (ARF) are a family of transcription factors that mediate auxin signalling and regulate multiple biological processes. Their crucial role in increasing plant biomass/yield influenced this study, where a systematic analysis of ARF gene family was carried out to identify the key proteins controlling embryo/seed developmental pathways in Pigeonpea. A genome-wide scan revealed the presence of 12 ARF genes in pigeonpea, distributed across the chromosomes 1, 3, 4, 8 and 11. Domain analysis of ARF prot...

Routine MRI Among Patients With a Suspected Scaphoid Fracture Risks Overdiagnosis
CONCLUSION: The high prevalence of signal changes that are distracting and potentially misleading, the low prevalence of signal changes that clearly represent a scaphoid fracture, and the low pretest odds of a true fracture among patients with a suspected scaphoid fracture illustrate that routine MRI of suspected scaphoid fractures carries a notable risk of overdiagnosis and potential overtreatment. Two alternative strategies are supported by preliminary evidence and merit additional attention: more-selective use of MRI in people deemed at higher risk according to a clinical prediction rule and strategies for involving the...

The effect of postoperative hepatic fibrosis factors on morbidity in mitral valve replacement surgery: A single center ten years' experience
CONCLUSION: The AST/ALT ratio, which has been shown to be a predictor of cardiovascular mortality in various studies, was not useful in predicting mortality and morbidity in our study. However, a high FIB-4 index, another hepatic fibrosis index, was found to be associated with increased perioperative bleeding, duration of mechanical ventilation, and cardiac intensive care unit stay, which are important criteria in the prediction of morbidity in cardiovascular surgery.PMID:37706385 | PMC:PMC10284468 | DOI:10.4103/aca.aca_55_22

Highly selective molecularly imprinted polymer nanoparticles (MIP NPs)-based microfluidic gas sensor for tetrahydrocannabinol (THC) detection
Anal Chim Acta. 2023 Oct 16;1278:341749. doi: 10.1016/j.aca.2023.341749. Epub 2023 Aug 22.ABSTRACTA highly selective microfluidic integrated metal oxide gas sensor for THC detection is reported based on MIP nanoparticles (MIP NPs). We synthesized MIP NPs with THC recognition sites and coated them on a 3D-printed microfluidic channel surface. The sensitivity and selectivity of coated microfluidic integrated gas sensors were evaluated by exposure to THC, cannabidiol (CBD), methanol, and ethanol analytes in 300-700 ppm at 300 °C. For comparison, reference signals were obtained from a microfluidic channel coated with nonimpri...

Does who you live with matter for your health? The influence of partners' socioeconomic characteristics on self-rated health in Norway
CONCLUSIONS: Our findings suggest that health is affected by the resources (or lack thereof) in one's immediate networks. To reduce social inequalities in health, health personnel might customise interactions to account for household resources. Such knowledge could also be used in health-promoting activities to enhance participation and health competency.PMID:37705349 | DOI:10.1177/14034948231197453

A molecularly imprinted screen-printed carbon electrode for electrochemical epinephrine, lactate, and cortisol metabolites detection in human sweat
This study presents a novel approach to the detection of epinephrine, lactate, and cortisol biomarkers in human sweat using molecularly-imprinted polymers (MIP) embedded screen printed carbon electrode (SPCE) sensors. The epinephrine and lactate MIP SPCE sensors were fabricated by epinephrine or lactate-imprinted polyaniline co-polymerized with 3-aminophenylboronic acid and gold nanoparticles (PANI-co-PBA/AuNP) selective membrane on a commercial SPCE. The cortisol sensor was comprised of a cortisol-imprinted poly(glycidyl methacryate-co-ethylene glycol dimethacrylate) (poly (GMA-co-EGDMA)@AuNP selective membrane deposited ...
