by using UDS, a plus of two DRMs per patient becomes visible, which can make a big difference in the assessment of the expected resistance behavior of the virus.Natural products contain bioactive compounds that are produced naturally via synthetic or semisynthetic processes. These bioactive compounds play significant biological roles, especially for growth as well as in defence mechanisms against pathogens. Bioactive compounds in natural products have been extensively studied in recent decades for their pharmacological activity such as anti-cancer, wound healing, anti-microbial, anti-inflammatory, and anti-oxidative properties. However, their pharmaceutical significance has always been hindered by their low bioavailability, and instability with variations of pH, temperature, and exposure to light. Nanotechnology paves the way for the development of drug delivery systems by enhancing therapeutic efficacy. Nanostructured lipid carriers, a lipid-based drug delivery system, are recently being studied to improve the biocompatibility, biodegradability, bioavailability, solubility, permeability, and shelf life of bioactive compounds in the pharmaceutical industry. The ideal component and preparation method for bioactive compounds in nanostructured lipid carrier development is necessary for their physicochemical properties and therapeutic efficiency. Therefore, this review seeks to highlight recent developments, preparation, and application of nanostructured lipid carriers as carriers for natural bioactive compounds in improving their therapeutic potential in drug delivery systems.Liposome nanoparticles (LNPs) as a promising platform in drug delivery, combine the advantages of both liposomes and inorganic/organic nanoparticles into a single system. Both liposomes and nanoparticles have demonstrated the optimized drug efficacy in clinic. LNPs are proven to be a multifunctional system and thus utilized in various research applications (e.g., spatiotemporal control of drug release, hyperthermia, photothermal therapy, and biological imaging). The type of nanoparticles involved in LNPs largely affects the features of LNPs. Besides, diverse nanoparticlesenable liposomes to overcome the defects such as poor stability, few functions and rapid elimination from blood circulation. In this review, multiple nanoparticles materials and further prepared LNPs as well as their structure, physicochemical properties, manipulation and the latest applications in biomedical field are introduced. Future directions in advancing of LNPs are also discussed in the end.

Lipid nanocarriers have great potential for the encapsulation and delivery of numerous bioactive compounds. They have demonstrated significant benefits over traditional disease management and conventional therapy. see more The benefits associated with the particular properties of lipid nanocarriers include site-specific drug deposition, improved pharmacokinetics and pharmacodynamics, enhanced internalization and intracellular transport, biodegradability, and decreased biodistribution. These properties result in the alleviation of the harmful consequences of conventional treatment protocols.

The administration of various bioactive molecules has been extensively investigated using nanostructured lipid carriers. In this article, theranostic applications of novel formulations of lipid nanocarriers combined or complexed with quantum dots, certain polymers, such as chitosan, and metallic nanoparticles (particularly gold) are reviewed. These formulations have demonstrated better controlled release features, improved drug loading capability, as well as a lower burst release rate. As a recent innovation in drug delivery, tocosomes and their unique advantages are also explained in the final section of this review.

Theranostic medicine requires nanocarriers with improved target-specific accumulation and bio-distribution. To this end, lipid-based nanocarrier systems and tocosomes combined with unique properties of quantum dots, biocompatible polymers, and metallic nanoparticles seem to be ideal candidates to be considered for safe and efficient drug delivery.

Cellular damage by oxidation is present in numerous chronic diseases, such as obesity, type II diabetes, cardiovascular disease, and nonalcoholic fatty liver, among others. The oxidized compound 3-nitrotyrosine is a marker of oxidative stress and protein oxidation damage. The objective of this work is to establish by means of 3-nitrotyrosine whether this marker in young people with obesity is higher than in the same population without obesity.

Anthropometry and blood chemistry analyses were performed on 24 young Mexican participants (18-30 years old), forming two groups based on their waist circumference With Obesity (≥ 80 cm women;> 90 cm men) and Without-Obesity (<80 cm women; <90 cm men). Additionally, 3-nitrotyrosine blood values were quantified by ELISA.

Except for HDL-cholesterol, the mean values of lipids increase in women and men With Obesity (p<0.05), and 3-nitrotyrosine concentration (nM/μg total protein) was higher by 60% in the group With Obesity compared to the group Without Obesity, both for women (66.21 ± 23.85 vs. 40.69 ± 16.25, p<0.05) and men (51.72 ± 20.56 vs. 30.52 ± 5.21, p<0.05).

Oxidative damage measured by compound 3-nitrotyrosine is higher in the groups With Obesity than in the groups Without Obesity, which if not controlled can lead to a chronic oxidative condition and thereby to a degree of cellular aging with diverse health effects.

Lung cancer is cancer with the highest incidence in the world, and there is obvious heterogeneity within its tumor. The emergence of single-cell sequencing technology allows researchers to obtain cell-type-specific expression genes at the single-cell level, thereby obtaining information regarding the cell status and subpopulation distribution, as well as the communication behavior between cells. Many researchers have applied this technology to lung cancer research, but due to the shortcomings of insufficient sequencing depth, only a small part of the gene expression can be detected. Researchers can only roughly compare whether a few thousand genes are significant in different cell types.

To fully explore the expression of all genes in different cell types, we propose a method to predict cell-type-specific genes. This method infers cell-type-specific genes based on the expression levels of genes in different tissues and cells and gene interactions. At present, biological experiments have discovered a large number of cell-type-specific genes, providing a large number of available samples for the application of deep learning methods.

Therefore, we fused Graph Convolutional Network (GCN) with Convolutional Neural Network( CNN) to build, model, and inferred cell-type-specific genes of lung cancer in 8 cell types.

This method further analyzes and processes single-cell data and provides a new basis for research on heterogeneity in lung cancer tumor, microenvironment, invasion and metastasis, treatment response, drug resistance, etc.

Although many mutations can be marked in the genome of cancer or a transformed cell, the initiation and progression are driven by only a few mutational events, viz., driver mutations that progressively govern and execute the functional impacts. The driver mutations are thus believed to dictate and dysregulate the subsequent cellular proliferative function/decisions, thereby producing a cancerous state. Therefore, identifying the driver events from the genomic alterations in a patient's cancer cell gained enormous attention recently for designing better targeting therapies and paving the way for precision cancer medicine. With rolling advancements in high-throughput omic technologies, analysis of genetic variations and gene expression profiles for cancer patients has become a routine clinical practice. However, it is anticipated that protein structural alterations resulting from such driver mutations can provide more direct and clinically relevant evidence of disease states than genetic signatures alone. This review comprehensively discusses various aspects and approaches that have been developed for the prediction of cancer drivers using genetic signatures and protein structures and their potential application in developing precision cancer therapies.

The medicinal properties of plants can be predicted by virtue of phylogenetic methods, which nevertheless has not been utilized to explore the regularity of skin related bioactivities of ethnomedicinal plants. We aim to investigate the distribution of skin efficacy of Asteraceae and Ranunculales plants on the species-level Tree of Life.

The clinical efficacy data of 551 ethnomedicinal species belonging to Ranunculales, as well as 579 ethnomedicinal species of Asteraceae, were systematically collected and collated; these therapeutic data fell into 15 categories, including skin disease/cosmeceutical. The large phylogenetic tree of all China angiosperm species was used to detect the phylogenetic signals of ethnomedicinal plants by calculating the D statistic, phylogenetic diversity (PD), net relatedness index (NRI) and nearest taxon index (NTI). Of all Chinese ethnomedicinal plants of Ranunculales and Asteraceae, 339 (61.5% of all ethnomedicinal species) and 382 (66.0% of all) are used for skin problems. In with skin utilities is validated.

Atherosclerosis (AS) remains prevalent despite hyperlipidemia-lowering therapies. Although multiple functions of miR-199b-5p have been implicated in cancers, its role in endothelial apoptosis and AS remains unclear. This study aimed to examine the role of miR-199b-5p in mitochondrial dynamics and endothelial apoptosis.

Human umbilical vein endothelial cells (HUVECs) treated with oxidized low-density lipoprotein (ox-LDL) were subjected to other treatments, followed by a series analysis. We found that ox-LDL-treated HUVECs were associated with miR-199b-5p downregulation, increased reactive oxygen species level, reduced adenosine triphosphate (ATP) production, mitochondrial fission, and apoptosis, whereas enhanced miR-199b-5p expression or applied mitochondrial division inhibitor 1 (Mdivi-1) markedly reversed these changes.

Mechanistically, A-kinase anchoring protein 1 (AKAP1) was confirmed as a downstream target of miR-199b-5p by dual-luciferase activity reporter assay. AKAP1 overexpression reversed the anti-apoptotic effects of miR-199b-5p through the enhanced interaction of AKAP1 and dynamin protein 1 (DRP1) in ox-LDL-treated HUVECs.
