Pooled nanoparticle screening using a chemical barcoding approach.

We report the development of a small molecule-based barcoding platform for pooled screening of nanoparticle delivery. Using aryl halide-based tags (halocodes), we achieve high-sensitivity detection via gas chromatography coupled with mass spectrometry or electron capture. This enables barcoding and tracking of nanoparticles with minimal halocode concentrations and without altering their physicochemical properties.

Investigation of a novel Schiff base Catena-((μ-(E)-2-((4-methoxy-2-oxidobenzylidene)ammonio)ethane-1-sulfonato potassium as a potential antibacterial agent.

Context: Schiff bases, which have intriguing properties in many areas, have been studied extensively in recent years due to their structural properties and biological activities. In this research, a novel water-soluble Schiff base complex, Catena-((μ-(E)-2-((4-methoxy-2-oxidobenzylidene) ammonio) ethane-1-sulfonato potassium, CHKNOS (CMOAESP), was synthesized by a one-step condensation reaction of 2-hydroxy-4-methoxy benzaldehyde and taurine with the yield of 65%, 0.333 g.

Methods And Materials: The need for improved education around GO is internationally recognized and is a key strategic priority of the International Society of Geriatric Oncology (SIOG).Two reviewers undertook a systematic scoping review from March to September 2023.

Examining unmet needs in older adults with lung cancer: A systematic review and narrative synthesis.

Introduction: Unmet needs in the older population with cancer are complex due to aging-related health conditions. A review of unmet needs in older people with cancer showed that needs varied among different cancer types. In lung cancer, a higher incidence of geriatric syndromes and comorbidities exist compared to other cancer cohorts, impacting treatment tolerance and completion.

Site-specific impact of polyphenols on the gastrointestinal microbiome.

The gastrointestinal (GI) tract hosts a diverse microbiota composed of trillions of microorganisms that play crucial roles in maintaining human homeostasis, health, and overall well-being. Dietary polyphenols, primarily found in edible plants, exhibit intricate interactions with the GI microbiota. These polyphenols undergo biotransformation by microbial activity and can modulate the growth of microorganisms, either promoting or inhibiting their proliferation.

Insights into the in vitro biological properties of Australian beach-cast brown seaweed phenolics.

Five Australian seaweed species, , , , , and , thrive along the country's shorelines. Some of these seaweeds have recognized health benefits but have not been fully investigated in terms of their bioactive components and mechanisms of action. We employed ultrasonication with 70% methanol to extract phenolic compounds from these seaweeds and investigated a range of bioactivities for these extracts, including anti-inflammatory activity exploring urease inhibition, nitric oxide scavenging activity, protein denaturation inhibition, and protease inhibition.

Electrochemical quantification based on the interactions of nucleoside analog cladribine with dsDNA via experimental and in-silico studies.

Cladribine is a deoxyadenosine analog prodrug originally developed to treat hairy-cell leukemia and other lymphoproliferative diseases. However, it is now primarily used in the treatment of relapsing types of multiple sclerosis (MS). Understanding how medications interact with dsDNA is crucial for developing more effective and efficient medications.

Safety and Effectiveness of a Novel Liposomal Intra-Articular Lubricant in Symptomatic Knee Osteoarthritis: A First-in-Human Study.

Osteoarthritis (OA) is a common disease that affects almost half the population at some point in their lives, causing pain and decreased functional capacity. New conservative treatment modalities are being proposed to provide symptomatic relief and delay surgical intervention. This study aimed at evaluating the safety of the novel liposomal boundary lubricant, injected intra-articularly in patients with moderate knee OA.

Pulsed peritoneal dialysis in an experimental rat model: A first experience.

Background: Peritoneal dialysis (PD) is commonly performed using either intermittent or tidal exchanges, whereas other exchange techniques such as continuous flow PD are little used. Previous research indicated that stirring the intra-peritoneal dialysate markedly increases small solute clearances. Here, we tested the hypothesis that stirring of the dialysate increases small solute clearances by using a novel exchange technique where the dialysate is pulsed back and forth during the treatment without addition of fresh fluid.

Approach to allergic rhinitis in the primary care setting.

Background: Allergic rhinitis (AR) is a common condition that affects 19% of Australians in the community, accounting for approximately 0.6% of all general practitioner presentations. Recent years have seen the emergence of new treatment options, many of which can be delivered in the primary care setting.

Non-invasive assessment of intracranial pressure through the eyes: current developments, limitations, and future directions.

Detecting and monitoring elevated intracranial pressure (ICP) is crucial in managing various neurologic and neuro-ophthalmic conditions, where early detection is essential to prevent complications such as seizures and stroke. Although traditional methods such as lumbar puncture, intraparenchymal and intraventricular cannulation, and external ventricular drainage are effective, they are invasive and carry risks of infection and brain hemorrhage. This has prompted the development of non-invasive techniques.

Implementing palliative care in hepatocellular carcinoma ambulatory clinics-study protocol for Accelerated translational research in PRImary liver CAncer (APRICA) randomised controlled palliative care trial.

Background: Integration of symptom and palliative care for people with advanced cancer is established in many tumour types, but its role in people with hepatocellular carcinoma (HCC) has not been clearly defined. This study aims to evaluate the clinical and cost effectiveness of an intervention involving a suite of strategies designed to assess and treat palliative care symptoms and needs in adult outpatients with HCC attending four New South Wales (NSW) metropolitan tertiary hospitals.

Methods: This trial will use a pragmatic cluster-based randomised-controlled design, with ambulatory HCC services as the clusters.

Pilot Trial of Perampanel on Peritumoral Hyperexcitability in Newly Diagnosed High-grade Glioma.

Purpose: Glutamatergic neuron-glioma synaptogenesis and peritumoral hyperexcitability promote glioma growth in a positive feedback loop. The objective of this study was to evaluate the feasibility and estimated effect sizes of the targeted AMPA receptor antagonist perampanel on peritumoral hyperexcitability.

Experimental Design: An open-label trial was performed comparing perampanel with standard of care (SOC) in patients undergoing resection of newly diagnosed radiologic high-grade glioma.

DNA-PK inhibition shows differential radiosensitization in orthotopic GBM PDX models based on DDR pathway deficits.

Glioblastoma (GBM) remains one of the most therapy-resistant malignancies with frequent local failures despite aggressive surgery, chemotherapy, and ionizing radiation (IR). Small molecule inhibitors of DNA-dependent protein kinase (DNA-PKi's) are potent radiosensitizers currently in clinical trials. Determining which patients may benefit from radiosensitization with DNA-PKi's is critical to avoid unnecessary increased risk of normal tissue toxicity.

Detection of Thymoma Disease Using mRMR Feature Selection and Transformer Models.

Background: Thymoma is a tumor that originates in the thymus gland, a part of the human body located behind the breastbone. It is a malignant disease that is rare in children but more common in adults and usually does not spread outside the thymus. The exact cause of thymic disease is not known, but it is thought to be more common in people infected with the EBV virus at an early age.
