The development of the phage display technique has brought practicality and speed when selecting high-affinity molecules. It is used to obtain single-chain variable fragments (scFvs) and has revolutionized several branches of research and industry. These are developed from gene libraries that differ in their construction strategies, which causes a diversity of sequences, specificity and binding strength of the projected molecule to its antigen.

Objective: To facilitate medication adherence among older adults with MCC and polypharmacy in primary care, we are adapting a technology-enabled intervention previously implemented in a specialty clinic.
Introduction: Pro-resolving molecules may curb disease caused by viruses without altering the capacity of the host to deal with infection. AP1189 is a melanocortin receptor-biased agonist endowed with pro-resolving and anti-inflammatory activity. We evaluated the preclinical and early clinical effects of treatment with AP1189 in the context of COVID-19.

This review focuses on recent research exploring the interaction between cancer cell-expressed chemokine receptor 4 (CXCR4) and ligand-conjugated NPs, utilising small molecules, peptides, and antibodies. Active NP targeting has shown improved tumour targeting and reduced toxicity, enabling precision therapy and diagnosis.

For colloidal stability, Alg-coated HPIONPs maintained size stability up to 24 h, with only an 18% increase, while Chi, PEG, and uncoated HPIONPs showed larger size increases ranging from 64 to 140%. The biocompatibility of polymer-coated HPIONPs was evaluated by assessing their cell viability, genotoxicity, and hemocompatibility.
View Article and Find Full Text PDFBackground: People living with HIV (PLWH) are at higher risk of developing type 2 diabetes (T2DM). Both chronic conditions require individuals to adhere to medication regimens, yet few studies have sought to explore medication-taking behaviors among individuals with comorbid HIV and T2DM (HIV+T2DM).
Objective: This qualitative study sought to: 1) identify and compare perceived determinants of medication adherence for HIV and, separately, for T2DM, and 2) explore how participants prioritize conditions.
In this paper, we-a participatory action group-use the tenants of critical pedagogy to articulate how youths developed relationships for and with STEM disciplinary practices through participation in spaces outside of the official scripts of their high school STEM classrooms in the United States. Spaces included their robotics team, a hybrid digital collaborative space, and in an extra project with a teacher. Each of these cases surfaces youth's ongoing orientation to the fact that STEM learning is relational, and political, exemplifying pockets of resistance against the structures of schooling that foreground learning as an act of individuals.

In this study, folic acid (FA)-grafted chitosan-alginate nanocapsules (CS-Alg-NCs) loaded with turmeric oil (TO) were developed for breast cancer targeting. CS was successfully conjugated with FA via an amide bond with a degree of substitution at 12.
View Article and Find Full Text PDFFavipiravir (FVR) is a repurposed antiviral drug for treating mild to moderate cases of the novel coronavirus disease 2019 (COVID-19). However, its poor solubility and permeability limit its clinical efficacy. To overcome its physicochemical and pharmacokinetic limitations, we statistically designed a mucoadhesive chitosan-alginate nanoparticles (MCS-ALG-NPs) as a new carrier for FVR using response surface methodology, which provided suitable characteristics for transmucosal delivery.
View Article and Find Full Text PDFTurmeric oil (TO) exhibits various biological activities with limited therapeutic applications due to its instability, volatility, and poor water solubility. Here, we encapsulated TO in chitosan/alginate nanocapsules (CS/Alg-NCs) using o/w emulsification to enhance its physicochemical characteristics, using poloxamer 407 as a non-ionic surfactant. TO-loaded CS/Alg-NCs (TO-CS/Alg-NCs) were prepared with satisfactory features, encapsulation efficiency, release characteristics, and cytotoxicity against breast cancer cells.

This study used tetrahydrocurcumin (THC), a primary metabolite of curcumin with enhanced antioxidant and anticancer properties, as a model compound to prepare NLCs. Response surface methodology was employed to optimize THC-loaded Ch-coated NLCs (THC-Ch-NLCs) fabricated by high-shear homogenization.

Recently, American Urological Association guidelines distinguish surgical interventions for men with large prostates (80 mL-150 mL) and now very large prostates (> 150 mL). Readers will gain an understanding of how to use Aquablation in the very large prostate size category.
View Article and Find Full Text PDFPhosphatase and tensin homolog deleted on chromosome 10, or PTEN, is a well-characterized tumor suppressor with both lipid and protein phosphatase activities. PTEN is often downregulated by epigenetic mechanisms such as hypermethylation, which leads to constitutive activation of the PI3K-Akt pathway. Large datasets from next-generation sequencing, however, revealed that mutations in PTEN may not only hamper protein function but may also affect interactions with downstream effectors, leading to variable oncogenic readouts.

While the clinical outcomes and benefits of Aquablation have been studied for men with average and large prostates, it is unknown whether this technology can be used for very large prostates.
Materials And Methods: Men with PV > 150 mL undergoing Aquablation were identified retrospectively from four North American hospitals.

PTEN inactivation is a frequent event in oncogenesis. Multiple regulatory mechanisms such as promoter hypermethylation, antisense regulation, histone modifications, targeting by microRNAs (miRNAs/miRs) and regulation by transcription factors have all been shown to affect the tumor suppressor functions of PTEN. More recently, the functional involvement of competing endogenous RNAs (ceRNAs) in miRNA‑dependent and coding‑independent regulation of genes shed light on the highly nuanced control of PTEN expression.

In colorectal cancer, Kirsten-RAS (KRAS) and neuroblastoma-RAS (NRAS) are the commonly mutated isoforms. Activating mutations in RAS result in cellular transformation independent of upregulated epidermal growth factor receptor (EGFR)-initiated signaling.
