Metabolic immunoengineering approaches to enhance CD8 T cell-based cancer immunotherapy.

Many cancer immunotherapies rely on robust CD8 T cells capable of eliminating cancer cells and establishing long-term tumor control. Recent insights into immunometabolism highlight the importance of nutrients and metabolites in T cell activation and differentiation. Within the tumor microenvironment (TME), CD8 tumor-infiltrating lymphocytes (TILs) undergo metabolic adaptations to survive but compromise their effector function and differentiation.

A Graph-based Goat Pangenome Reveals Structural Variations Involved in Domestication and Adaptation.

Pangenomes can facilitate a deeper understanding of genome complexity. Using de novo phased long-read assemblies of eight representative goat breeds, we constructed a graph-based pangenome of goats (Capra hircus) and discovered 113-Mb autosomal novel sequences. Combining this multi-assembly pangenome with low-coverage PacBio HiFi sequences, we constructed a long-read structural variations (SVs) database containing 59,325 SV deletions, 84,910 SV insertions, and 24,954 other complex SV alleles.

Bioactive compounds from Bge. leaves: potential health benefits.

The leaves of Bge., a medicinal plant and a source of brewed tea, are often overlooked as a byproduct of fruit consumption. Despite this, these leaves have demonstrated significant cardiovascular protective and lipid-lowering properties.

Treatment of constipation with and its compatibility prescriptions.

Constipation is a common and prevalent digestive system disease in clinical practice, which seriously affects human physical and mental health. Currently, chemical drugs have good short-term therapeutic effects. However, because of their adverse reactions, easy recurrence after drug discontinuation, and dependence with long-term use, the long-term efficacy is unsatisfactory.

Breaking Mass Transport Limit for Hydrogen Evolution-Inhibited and Dendrite-Free Aqueous Zn Batteries.

It is commonly accepted that batteries perform better at low current densities below the mass-transport limit, which restricts their current rate and capacity. Here, it is demonstrated that the performance of Zn metal electrodes can be dramatically enhanced at current densities and cut-off capacities exceeding the mass-transport limit by using pulsed-current protocols. These protocols achieve cumulative plating/stripping capacities of 11.

Fasting-mimicking diet potentiates anti-tumor effects of CDK4/6 inhibitors against breast cancer by suppressing NRAS- and IGF1-mediated mTORC1 signaling.

Aims: Acquired resistance to cyclin-dependent kinase 4/6 inhibitors (CDK4/6i) frequently emerges, and CDK4/6i-containing therapies in triple-negative breast cancer (TNBC) remain to be determined.

Methods: RNA-sequencing, cell viability analysis, immunoblotting, siRNA transfection et al. were used to investigate and verify the resistance mechanism.

Co-design and evaluation of an audio podcast about sustainable development goals for undergraduate nursing and midwifery students.

Background: Sustainable Development Goals (SDGs) are universally recognised targets designed to combat poverty, inequality, and climate change. However, there exists limited awareness and understanding of these goals among nursing and midwifery students. To address this knowledge gap, a co-designed audio podcast was introduced as an educational tool to enhance students' comprehension of SDGs and their relevance to the healthcare profession.

A multidimensional analysis of the impact of obesity on immune checkpoint inhibitor therapy efficacy.

Background: Obesity is a well-known risk factor for developing malignant tumors and promoting tumor cell growth and spread. However, recent studies have shown that obese cancer patients, who typically have a worse prognosis than nonobese cancer patients, show a significant improvement in survival after receiving immune checkpoint inhibitor (ICI) therapy. This phenomenon is known as the "obesity paradox".

The application of Chinese version of SARC-F and SARC-CalF in sarcopenia screening against five definitions: a diagnostic test accuracy study.

Background: SARC-F questionnaire is a simple and convenient tool for sarcopenia screening, and SARC-CalF is a modified version of it. The developments of their Chinese versions are warranted for the clinical use for Chinese population. This study aimed to culturally adapt the SARC-F questionnaire into Chinese using standardized methods, validate the reliability and diagnostic accuracy of the Chinese version SARC-F and SARC-CalF against five sarcopenia diagnosis criteria, and determine optimal cut-off values for clinical practice in Chinese population.

STUB1-mediated ubiquitination and degradation of NSUN2 promotes hepatocyte ferroptosis by decreasing mC methylation of Gpx4 mRNA.

Ferroptosis is an iron-dependent cell death that occurs due to the peroxidation of phospholipids in the cell membrane. In this study, we find that the protein level of NSUN2 is significantly decreased in hepatocyte ferroptosis. This is attributed to STUB1-mediated ubiquitination of NSUN2 at lysines 457 and 654, promoting NSUN2 degradation in ferroptosis.

Smoking cessation and mortality risk reduction in older adults with long-term smoking history.

Background: The association between smoking cessation and decreased mortality existed among former smokers has been well documented. However, evidence is limited for smokers with long-term exposure. This study aims to quantify the association between smoking cessation and mortality by years since quitting in older adults with long-term smoking history.

[Electroacupuncture with different frequencies for paclitaxel-induced peripheral neuropathy: a randomized controlled trial].

Objective: To observe the clinical efficacy of electroacupuncture (EA) at frequencies of 2 Hz, 100 Hz, and 2 Hz/100 Hz for chemotherapy-induced peripheral neuropathy (CIPN).

Methods: One hundred and sixty female breast cancer patients with CIPN induced by paclitaxel were randomly divided into a 2 Hz EA group (40 cases, 1 case dropped out), a 100 Hz EA group (40 cases, 2 cases dropped out), a 2 Hz/100 Hz EA group (40 cases, 3 cases dropped out), and a medication group (40 cases, 2 cases dropped out). The three EA groups received acupuncture at bilateral Quchi (LI 11), Waiguan (TE 5), Hegu (LI 4), Zusanli (ST 36), and Yanglingquan (GB 34).

Chromosome-Level Genome Assembly for the Chinese Serow () Provides Insights Into Its Taxonomic Status and Evolution.

Chinese serow () is mainly distributed in the south of Yellow River in China, which has been listed as vulnerable by the International Union for Conservation of Nature (IUCN). However, the reference genome of serow has not been reported and its taxonomic status is still unclear. Here, we first constructed a high-quality chromosome-level reference genome of using PacBio long HiFi reads combined with Hi-C technology.

The type 2 cytokine Fc-IL-4 revitalizes exhausted CD8 T cells against cancer.

Current cancer immunotherapy predominately focuses on eliciting type 1 immune responses fighting cancer; however, long-term complete remission remains uncommon. A pivotal question arises as to whether type 2 immunity can be orchestrated alongside type 1-centric immunotherapy to achieve enduring response against cancer. Here we show that an interleukin-4 fusion protein (Fc-IL-4), a typical type 2 cytokine, directly acts on CD8 T cells and enriches functional terminally exhausted CD8 T (CD8 T) cells in the tumour.

An innovative metabolic index for insulin resistance correlates with early neurological deterioration following intravenous thrombolysis in minor acute ischemic stroke patients.

Background And Purpose: The composite score for insulin resistance (IR), known as the Metabolic Score of Insulin Resistance (METS-IR), serves as an assessment tool for IR and has been previously linked to symptomatic intracranial hemorrhage and poor functional outcomes in patients with acute ischemic stroke (AIS). Despite these associations, the impact of METS-IR on early neurological deterioration (END) in patients with minor AIS who underwent intravenous administration of recombinant tissue-type plasminogen activator (IV-rtPA) remains inadequately established. This investigation explored the link between METS-IR and END in patients with minor AIS receiving IV-rtPA treatment.

Metabolic processes drive spatio-temporal variations of carbon sink/source in a karst river.

Riverine carbon dioxide (CO) exchange is a crucial component of the global carbon cycle. However, the changes in the CO sink/source in karst rivers caused by differences in lithological features and climate, hindered the resolution of the spatio-temporal heterogeneity of global inland water carbon emissions. Here, we use hydrochemical data and CO gas isotopic data to reveal the spatio-temporal variations of CO sink/source in karst rivers and their controlling mechanisms.

Dynamics of Physiological Properties and Endophytic Fungal Communities in the Xylem of (Lour.) with Different Induction Times.

Xylem-associated fungus can secrete many secondary metabolites to help trees resist various stresses and play a crucial role in facilitating agarwood formation. However, the dynamics of endophytic fungi in xylem after artificial induction have not been fully elaborated. Endophytic fungi communities and xylem physio-biochemical properties were examined before and after induction with an inorganic salt solution, including four different times (pre-induction (0M), the third (3M), sixth (6M) and ninth (9M) month after induction treatment).

Barrierless reactions of C2 Criegee intermediates with HSO and their implication to oligomers and new particle formation.

The formation of oligomeric hydrogen peroxide triggered by Criegee intermediate maybe contributes significantly to the formation and growth of secondary organic aerosol (SOA).
