Green technologies applied to extraction processes and analysis of polyphenolic compounds from Inga laurina Willd.

This study aimed to identify an efficient and sustainable extraction method for phenolic compounds and flavonoids from I. laurina using maceration (conventional), ultrasonic bath and probes, cup horn sonication, and microwave. It evaluated extraction parameters and assessed total phenolic compounds, flavonoids, antioxidant, and antimicrobial capacities, with annotated compounds via ESI-ToF-MS and the green analytical procedure index analysis.

No impact of story context and avatar power on performance in a stop-signal game.

This study investigates the impact of gamification on response inhibition in a Stop-Signal Task (SST) and examines participants' gamification experience. The findings reveal that, after accounting for approach- and avoidance-motivation as well as impulsiveness, higher immersion is associated with impaired response inhibition. This effect could be attributed to a substantial decline in immersion between the first and second SST sessions.

[Neurogenic lower urinary tract dysfunction following spinal cord injury].

A spinal cord injury (SCI) leads to neurogenic lower urinary tract dysfunction (NLUTD), which, if left untreated, can result not only in urinary incontinence and an increased risk of urinary tract infections and kidney dysfunction but may also pose a vital threat to people with SCI. Comprehensive neurourological assessments, including patient history and combined video urodynamics, are essential to accurately classify dysfunction and establish therapeutic strategies. Treatment options include, among others, medications for detrusor regulation, intermittent catheterization, and, if necessary, surgical interventions from intradetrusor botulinum toxin A injections to sacral deafferentation.

Identifying Truly HPV-Driven Head and Neck Squamous Cell Carcinoma by QuantiGene-Molecular-Profiling-Histology Assay Allows for More Precise Prognosis Prediction.

Head and neck squamous cell carcinoma (HNSCC) with discordant diagnostic patterns of HPV/p16 or HPV/p16 correlate with worse prognosis. This study aims to identify truly HPV-driven HNSCCs using a QuantiGene-Molecular-Profiling-Histology (QG-MPH) assay for identifying transcriptionally active HPV. Of 97 FFPE samples analyzed, 68 were valid for HPV DNA detection by PCR and quantification of HPV E7 and p16 mRNA by QG-MPH.

Neuroarchitecture of the Central Complex in the Madeira Cockroach Rhyparobia maderae: Tangential Neurons.

Navigating in diverse environments to find food, shelter, or mating partners is an important ability for nearly all animals. Insects have evolved diverse navigational strategies to survive in challenging and unknown environments. In the insect brain, the central complex (CX) plays an important role in spatial orientation and directed locomotion.

Decomposition of L-glutamine and accumulation of ammonium in cell culture media inhibit infectivity of influenza viruses.

Cationic lysosomotropic molecules such as ammonium salts and chloroquine inhibit influenza A virus (IAV) infection in cell culture by counteracting endosomal acidification and hampering viral-endosomal fusion. Here, we studied the effects of storage of L-glutamine-supplemented cell culture media on accumulation of ammonium and inhibition of IAV infection. The storage-related inhibitory effect was observed for DMEM and OptiMEM media but not for RPMI medium, and was more pronounced for IAV with pH-stable hemagglutinin.

Extracranial-Intracranial Microsurgical Bypass Using a Y-Shaped Vein Graft From the Hand.

While extracranial-intracranial (EC-IC) bypass is commonly performed by neurosurgeons with specific expertise in cerebrovascular surgery, they can also be performed together with microvascular plastic surgeons. At our institution, some EC-IC bypass cases have evolved to be performed by neurosurgeons and plastic surgeons in a combined approach. Given the plastic surgeons' expertise and volume of experience in performing microvascular surgery, their skills are utilized in performing the donor vessel dissection as well as the bypass itself.

Community-based reconstruction and simulation of a full-scale model of the rat hippocampus CA1 region.

The CA1 region of the hippocampus is one of the most studied regions of the rodent brain, thought to play an important role in cognitive functions such as memory and spatial navigation. Despite a wealth of experimental data on its structure and function, it has been challenging to integrate information obtained from diverse experimental approaches. To address this challenge, we present a community-based, full-scale in silico model of the rat CA1 that integrates a broad range of experimental data, from synapse to network, including the reconstruction of its principal afferents, the Schaffer collaterals, and a model of the effects that acetylcholine has on the system.

Background And Objectives: Trigeminal Neuralgia (TN) is a debilitating facial pain disorder, often necessitating surgical interventions when medication proves insufficient. Stereotactic Radiosurgery (SRS) is an established therapeutic option. Limited studies explored the feasibility of a third SRS procedure.

Perceived causes of cancer in a rural community of Ethiopia: a qualitative study.

Background: Although cancer incidence and mortality are rising in Ethiopia, lay and health professional perceptions of the disease remain limited.

Objective: To explore perceptions of cancer, including its causes, signs and symptoms, and transmission within a rural community in Ethiopia.

Methods: We conducted a qualitative study in four rural neighbourhoods of Butajira in central Ethiopia.

Characterization of Camphene- and Fenchol-Based Hydrophobic Eutectic Solvents and Their Application in Aldehyde Extraction.

Binary terpenoid-based eutectic systems consisting of the natural substances camphene (CA), fenchol (FE), thymol (TH), menthol (ME), dodecanoic acid (DA), and 1-dodecanol (DO) are synthesized and screened for their Solid-Liquid Equilibrium (SLE) and eutectic compositions. Out of nine eutectic systems, 13 solvent compositions at eutectic points and next to them, in addition to the reference solvent, TH:ME, are synthesized and applied for the solvent extraction of the aromatic aldehydes vanillin (VAN), syringaldehyde (SYR), and -hydroxybenzaldehyde (HYD) from an acidic aqueous model solution. The extraction efficiency is determined from aldehyde concentrations measured by High-Performance Liquid Chromatography (HPLC), taking into consideration mutual solubility measured by Karl Fischer titration (KF) and a Total Organic Carbon-analysis (TOC).

Quantification of human papillomavirus cell-free DNA from low-volume blood plasma samples by digital PCR.

The incidence rate of human papillomavirus-driven oropharyngeal cancer (HPV-OPC) is increasing in countries with high human development index. HPV cell-free DNA (cfDNA) isolated from 3 to 4 mL blood plasma has been successfully used for therapy surveillance. A highly discussed application of HPV-cfDNA is early detection of HPV-OPC.

[Neurogenic, non-obstructive urinary retention: diagnosis and treatment].

Neurogenic, non-obstructive urinary retention has a varied aetiology. The condition can be caused by central-nervous diseases as well as by disorders of the peripheral nervous system. The formation of residual urine may lead to considerable problems that can have a significant impact on a patient's everyday life.

Distributional coding of associative learning in discrete populations of midbrain dopamine neurons.

Midbrain dopamine neurons are thought to play key roles in learning by conveying the difference between expected and actual outcomes. Recent evidence suggests diversity in dopamine signaling, yet it remains poorly understood how heterogeneous signals might be organized to facilitate the role of downstream circuits mediating distinct aspects of behavior. Here, we investigated the organizational logic of dopaminergic signaling by recording and labeling individual midbrain dopamine neurons during associative behavior.

A type I interferon regulatory network for human plasmacytoid dendritic cells based on heparin, membrane-bound and soluble BDCA-2.

Plasmacytoid dendritic cells (pDCs) produce type I interferons (IFNs) after sensing viral/bacterial RNA or DNA by toll-like receptor (TLR) 7 or TLR9, respectively. However, aberrant pDCs activation can cause adverse effects on the host and contributes to the pathogenesis of type I IFN-related autoimmune diseases. Here, we show that heparin interacts with the human pDCs-specific blood dendritic cell antigen 2 (BDCA-2) but not with related lectins such as DCIR or dectin-2.

Acute management of ruptured cavernous malformation of the optic nerve: illustrative case.

Background: A cavernous malformation of the optic nerve (CMON) is a rare condition that often presents with an abrupt decline in vision. Acute management of ruptured optic nerve cavernous malformations is generally surgical, although the timing of surgery is controversial.

Observations: A 47-year-old female experienced the sudden loss of vision in her left eye.

Changing from lipoprotein apheresis to evolocumab treatment lowers circulating levels of arachidonic acid and oxylipins.

Background And Aims: Previous studies have shown that lipoprotein apheresis can modify the plasma lipidome and pro-inflammatory and pro-thrombotic lipid mediators. This has not been examined for treatment with protein convertase subtilisin/kexin type 9 inhibitors such as evolocumab, which are increasingly used instead of lipoprotein apheresis in treatment-resistant familial hypercholesterolemia. The aim of this study was to compare the effects of evolocumab treatment and lipoprotein apheresis on the fatty acid profile and on formation of lipid mediators in blood samples.

T-bet B cells are activated by and control endogenous retroviruses through TLR-dependent mechanisms.

Endogenous retroviruses (ERVs) are an integral part of the mammalian genome. The role of immune control of ERVs in general is poorly defined as is their function as anti-cancer immune targets or drivers of autoimmune disease. Here, we generate mouse-strains where Moloney-Murine Leukemia Virus tagged with GFP (ERV-GFP) infected the mouse germline.

Improved method robustness and ruggedness in liquid chromatography-mass spectrometry by increasing the acid content of the mobile phase.

Comparative Analysis of Alternate Measures of Readiness to Quit Smoking: Stages of Change and the Contemplation Ladder.

Purpose: Two methods of operationalizing readiness to quit smoking have been used extensively in prior research. An algorithm derived from the transtheoretical model classifies current smokers in distinct stages of precontemplation (not intending to quit in next 6 months), contemplation (serious intent to quit within 6 months), and preparation (serious intent to quit within 30 days). The Contemplation Ladder (CL) is a single-item continuous (0-10) rating.
