Expression Profile of Thymidine Kinase Genes in Cervical Squamous Cell Carcinoma Confirmed by Various Detection Methods.

Background: Thymidine kinases (TKs) are key enzymes involved in DNA synthesis and repair, with alterations in their expression associated with various cancers. Thymidine kinase 1 (TK1) and TK2 are cytosolic enzyme proteins that catalyze the addition of a gamma-phosphate group to thymidine. The existing literature on TK1 in cervical squamous cell carcinoma (CESC) fails to address the clinical role of TK1 overexpression and its possible molecular mechanism in CESC.

Modulating the Doping Effect for Carbon Nanotube-Based Thermoelectric Composites by Radical-Containing Naphthalene Diimides.

Carbon nanotube-based organic thermoelectric composites have garnered a significant amount of research interest due to their synergistic benefits of the high electrical conductivity of carbon nanotubes and the low thermal conductivity of organic materials. Nevertheless, the correlation between the organic molecular structures and the thermoelectric properties of these composite systems has remained largely unexplored. This study delves into the doping effects of radical-containing naphthalene diimides (NDIs) on single-walled carbon nanotubes (SWCNTs) through molecular engineering.

Preventive effect of imperatorin against doxorubicin-induced cardiotoxicity through suppression of NLRP3 inflammasome activation.

Cardiotoxicity is one of the major obstacles to anthracycline chemotherapy. Anthracycline cardiotoxicity is closely associated with inflammation. Imperatorin (IMP), a furocoumarin ingredient extracted from Angelica dahurica, might have potential activity in preventing anthracycline cardiotoxicity due to its anti-cancer, anti-inflammatory, anti-oxidant, cardioprotective properties.

Regulation of Cecal Microbiota and Improvement of Blood Lipids Using Walnut Non-Dairy Creamer in High-Fat Mice: Replacing Traditional Non-Dairy Creamer.

Non-dairy creamer is a class of microencapsulated powdered fats and oils that are widely used in the food industry. However, the oils used in it are hydrogenated vegetable oils, which contain large amounts of saturated fatty acids and are extremely harmful to the human body. This study investigated the effects of replacing hydrogenated vegetable oil with walnut oil to prepare walnut non-dairy creamer on lipid levels and intestinal microorganisms in mice.

Structural characteristics and nonvolatile metabolites of theabrownins and their impact on intestinal microbiota in high-fat-diet-fed mice.

This study prepared enzymatic theabrownins (TBs-e), alkaline theabrownins (TBs-a), and Pu-erh tea theabrownins (TBs-f), and investigated whether different preparation processes affected the structures, nonvolatile metabolites, and biofunctional activities of TBs. Structural characterization revealed that TBs were polymeric phenolic compounds rich in hydroxyl and carboxyl groups. Nontargeted metabolomics revealed that amino acids were the primary nonvolatile metabolites in TBs-e and TBs-a, accounting for over 70 % of the total nonvolatile content.

Ultrafast, Selective, and Highly Sensitive Nonchromatographic Analysis of Fourteen Cannabinoids in Cannabis Extracts, Δ8-Tetrahydrocannabinol Synthetic Mixtures, and Edibles by Cyclic Ion Mobility Spectrometry-Mass Spectrometry.

The diversity of cannabinoid isomers and complexity of Cannabis products pose significant challenges for analytical methodologies.

Safe Induction of Acute Inflammation with Enhanced Antitumor Immunity by Hydrogel-Mediated Outer Membrane Vesicle Delivery.

Acute inflammation has the potential for the recruitment of immune cells, inhibiting tumor angiogenesis, metastasis, and drug resistance thereby overcoming the tumor immunosuppressive microenvironment caused by chronic inflammation. Here, an acute inflammation inducer using bacteria outer membrane vesicles (OMVs) loaded in thermal-sensitive hydrogel (named OMVs-gel) for localized and controlled release of OMVs in tumor sites is proposed. OMVs trigger neutrophil recruitment and amplify acute inflammation inside tumor tissues.

Preparation and Characterization of Soluble Dietary Fiber Edible Packaging Films Reinforced by Nanocellulose from Navel Orange Peel Pomace.

The packaging problem with petroleum-based synthetic polymers prompts the development of edible packaging films. The high value-added reuse of navel orange peel pomace, which is rich in bioactive compounds, merited more considerations. Herein, nanocellulose (ONCC) and soluble dietary fiber (OSDF) from navel orange peel pomace are firstly used to prepare dietary fiber-based edible packaging films using a simple physical blend method, and the impact of ONCC on the film's properties is analyzed.

Modulation of cecal microbiota and fecal metabolism in mice by walnut protein.

Walnut meal is a by-product of walnut oil pressing, in which the protein content is more than 40%, which is an excellent food raw material, but at present, it is basically used as animal feed or discarded, which results in a great waste of resources, and its modulating effect on the intestinal microbiota is not clear. In this study, we used supercritically extracted walnut meal as a raw material, prepared walnut meal isolate protein (WP) by alkaline extraction and acid precipitation, and systematically analyzed its structure by Fourier infrared spectroscopy (FTIR), Raman spectroscopy (Raman), and scanning electron microscopy (SEM); meanwhile, we explored the effects of WP on the cecal bacterial flora and fecal metabolites of mice by microbiological and metabolomic techniques. The results showed that the protein content of WP prepared using alkaline extraction and acid precipitation was as high as 83.

Biomimetic nanodecoys deliver cholesterol-modified heteroduplex oligonucleotide to target dopaminergic neurons for the treatment of Parkinson's disease.

Parkinson's disease (PD) is the second most common neurodegenerative disorder characterized by the accumulation of α-synuclein (α-syn) aggregates called Lewy bodies leading to the gradual loss of dopaminergic (DA) neurons in the substantia nigra. Although α-syn expression can be attenuated by antisense oligonucleotides (ASOs) and heteroduplex oligonucleotide (HDO) by intracerebroventricular (ICV) injection, the challenge to peripheral targeted delivery of oligonucleotide safely and effectively into DA neurons remains unresolved. Here, we designed a new DNA/DNA double-stranded (complementary DNA, coDNA) molecule with cholesterol conjugation (Chol-HDO (coDNA)) based on an α-syn-ASO sequence and evaluated its silence efficiency.

Comprehensive cannabinoid profiling of acid-treated CBD samples and Δ-THC-infused edibles.

Δ-Tetrahydrocannabinol (Δ-THC) is increasingly popular as a controversial substitute for Δ-tetrahydrocannabinol (Δ-THC) in cannabinoid-infused edibles. Δ-THC is prepared from cannabidiol (CBD) by treatment with acids. Side products including Δ-THC and other isomers that might end up in Δ-THC edibles are less studied.

A simple and low-energy strategy for the separation of water and acetonitrile.

As acetonitrile is a widely used solvent for the chemical industry, the recovery of acetonitrile from acetonitrile wastewater is significant for both industrial cost reduction and environmental protection. In this article, a simple, low-energy, and low-cost strategy is proposed for the effective separation of acetonitrile from high-concentration acetonitrile wastewater. The approach is based on a sequential combination of two steps: salt-induced phase separation and hydrophobic filtration.

The polymorphisms of miR-146a SNPs are associated with asthma in Southern Chinese Han population.

Asthma, a prevalent disease characterized by innate and adaptive immune responses, has been associated with several risk factors including miR-146a. To better understand the potential impact of miR-146a SNPs on asthma susceptibility and clinical features in Southern Chinese Han population, we conducted a case-control to analyze two functional SNPs (rs2910164 and rs57095329) of the miR-146a (394 patients with asthma and 395 healthy controls). Our findings suggest that the rs2910164 C/G genotype may increase the risk for asthma in females, while the rs57095329 G/G genotype may be involved in the regulation of clinical characteristics of males with asthma.
