Engineering of insecticidal hybrid gene into potato chloroplast genome exhibits promising control of Colorado potato beetle, Leptinotarsa decemlineata (Coleoptera: Chrysomelidae)
Transgenic Res. 2023 Sep 14. doi: 10.1007/s11248-023-00366-6. Online ahead of print.ABSTRACTThe potato chloroplast was transformed with codon optimized synthetic hybrid cry gene (SN19) to mitigate crop losses by Colorado potato beetle (CPB). The bombarded explants (leaves and internode) were cultured on MS medium supplemented with BAP (2.0 mg/l), NAA (0.2 mg/l), TDZ (2.0 mg/l) and GA3 (0.1 mg/l); spectinomycin 50 mg/l was used as a selection agent in the medium. Leaf explants of cultivar Kuroda induced highest percentage (92%) of callus where cultivar Santae produced the highest percentage (85.7%) of transplastomic shoots....

Insights into the formulation properties, biocompatibility, and permeability of poorly water-soluble methoxyflavones with PEG400 and propylene glycol
Acta Pharm. 2023 Sep 14;73(3):385-404. doi: 10.2478/acph-2023-0030. Print 2023 Sep 1.ABSTRACTHerein, thermal and non-thermal techniques were used to elucidate the putative physical and chemical interactions between poorly water-soluble Kaempferia methoxyflavones and PEG400/propylene glycol. Additionally, the biocompatibility of methoxyflavone-glycol solutions was evaluated using Caco-2 cells whereas the absorptive transport was investigated by measuring the apparent permeability coefficient (P app) of the methoxyflavones and transepithelial electrical resistance (TEER) of the Caco-2 cell monolayer. Data from differential s...

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

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...

Phasic and tonic muscle synergies are different in number, structure and sparseness
This study aims at testing whether phasic and tonic components are generated by distinct phasic and tonic synergies or by the same set of synergies with phasic and tonic activation coefficients. The study also aims at characterizing the differences between the phasic and the tonic synergies. Using a comprehensive mapping of upper-limb point-to-point movements, synergies were extracted from phasic and tonic EMG signal separately, estimating the tonic components with a linear ramp model. The goodness of reconstruction (R2) as a function of the number of synergies was compared, and sets of synergies extracted from each datase...

Differences in diffusion tensor imaging parameters of brain white matter tracts between patients with myotonic dystrophy type 1 and type 2 - a retrospective single-centre study
CONCLUSIONS: Our results indicate diffuse disintegration of white matter pathways in DM patients, especially in the DM1 group. The damage to all types of fibres (association, commissural, and projection) may explain the diversity of clinical symptoms, which were more severe in the DM1 group of patients than in the DM2 group.CLINICAL IMPLICATIONS: DTI in patients with DM may help us to understand the neural mechanisms underlying brain involvement during the disease. In future, it may help to identify biomarkers for disease progression and treatment response.PMID:37706668 | DOI:10.5603/pjnns.95587

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 ...

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

White matter hyperintensity volume modifies the association between CSF vascular inflammatory biomarkers and regional FDG-PET along the Alzheimer's disease continuum
Neurobiol Aging. 2023 Aug 10;132:1-12. doi: 10.1016/j.neurobiolaging.2023.08.002. Online ahead of print.ABSTRACTIn older adults with abnormal levels of Alzheimer's disease neuropathology, lower cerebrospinal fluid (CSF) vascular endothelial growth factor (VEGF) levels are associated with lower [¹⁸F]-fluorodeoxyglucose positron emission tomography (FDG-PET) signal, but whether this association is (1) specific to VEGF or broadly driven by vascular inflammation, or (2) modified by vascular risk (e.g., white matter hyperintensities [WMHs]) remains unknown. To address this and build upon our past work, we evaluated whether 5...

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

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
