Single-cell RNA-seq offer new insights into the cell fate decision of the primordial germ cells.

The faithful production of primordial germ cells (PGCs) in vitro opens a wide range of novel applications in reproductive biology and medicine. However, the reproducibility of PGCs culture conditions across different laboratories or breeds remains a challenge. Therefore, it is necessary to research the molecular dynamics that lead to the gradual establishment of cultured PGCs lines network.

Pseudo-linkage or real-linkage of rust resistance genes in a wheat-Thinopyrum intermedium translocation line.

We analysed the chromosomal structures of two wheat-Thinopyrum intermedium addition lines Z4 and Z5 and resolved the linkage relationship between the leaf rust and stripe rust resistance genes in Z4. Wheat addition lines Z4 and Z5 carrying rust resistance genes from Thinopyrum intermedium (JJJJStSt, 2n = 6x = 42) together with three wheat lines involved in the production of these addition lines were analysed by rust response, 90K SNP genotyping, and molecular cytogenetic analysis. Seedling leaf rust (LR) responses to five diverse pathotypes indicated that the LR resistance gene(s) was located in translocation chromosome T3DS-3AS.

The Furan-Thiol-Amine Reaction Facilitates DNA-Compatible Thiopyrrole-Grafted Macrocyclization and Late-Stage Amine Transformation.

We here report an efficient DNA-compatible furan-thiol-amine reaction for macrocyclization and late-stage amine transformation. This reaction, conducted under mild conditions, enables the facile cyclization of DNA-conjugated linear peptides into thiopyrrole-grafted macrocycles regardless of ring size or side-chain modification with good to excellent conversion yields. Additionally, this strategy was employed for the late-stage transformation of terminal amines, serving as critical intermediates in the construction of DNA-encoded peptide libraries.

An anoikis-related gene signature predicts prognosis in patients with acute myeloid leukemia and immunotherapy.

Acute myeloid leukemia (AML) is a malignant blood disorder and the most common type of acute leukemia in adults. Notwithstanding the plethora of therapeutic modalities, a significant cohort of patients fail to respond to treatment and experience relapse. Anoikis, a distinct modality of programmed cell death, has been linked to cancer progression.

Association of systemic immune-inflammation index with all-cause and cardio-cerebrovascular mortality in individuals with diabetic kidney disease: evidence from NHANES 1999-2018.

Background: Emerging evidence suggests a potential role of immune response and inflammation in the pathogenesis of diabetic kidney disease (DKD). The systemic immune-inflammation index (SII) offers a comprehensive measure of inflammation; however, its relationship with the prognosis of DKD patients remains unclear.

Methods: Using data from the National Health and Nutrition Examination Survey (NHANES) spanning 1999 to 2018, this cross-sectional study involved adults diagnosed with DKD.

Multi-stimuli actuation of a photoresponsive azobenzene based molecular switch.

There has been considerable interest in building switching functions into self-assembled monolayers with switching actuated by external stimuli such as light, electrical current, heat, pressure or chemical changes. In this study, dual switching functionality has been built into azobenzene based molecular monolayers. Switching behaviour has been compared for unsubstituted azobenzene monolayer adsorbates and two other monolayers whose position on the terminal phenyl group is substituted by ethyl and isopropyl chains, respectively.

Machine learning-based prognostic prediction and surgical guidance for intrahepatic cholangiocarcinoma.

The prognosis following radical surgery for intrahepatic cholangiocarcinoma (ICC) is poor, and optimal follow-up strategies remain unclear, with ongoing debates regarding anatomic resection (AR) versus non-anatomic resection (NAR). This study included 680 patients from five hospitals, comparing a combination of eight feature screening methods and 11 machine learning algorithms to predict prognosis and construct integrated models. These models were assessed using nested cross-validation and various datasets, benchmarked against TNM stage and performance status.

Correlation of large cribriform carcinoma and "unfavorable histology" with other Gleason pattern 4 subtypes: A proof-of-principle study evaluating 485 radical prostatectomy specimens with proposal for the concept of "borderline histology".

Prostatic adenocarcinomas with large cribriform glands/intraductal carcinoma (LC/IDC), or the recently proposed unfavorable histology, are associated with adverse outcomes after radical prostatectomy. However, Gleason pattern 4 carcinomas without LC/IDC (or unfavorable histology) have minimal risk for aggressive clinical behavior after prostatectomy. As proof-of-principle study, we collected a cohort of 485 radical prostatectomy specimens to assess correlations between different subtypes of Gleason pattern 4 disease and the presence of adjacent high-risk prostatic adenocarcinoma, defined as LC/IDC or unfavorable histology.

Genetic association of type 2 diabetes and antidiabetic drug target with skin cancer.

Background: Several observational studies have suggested that type 2 diabetes (T2D) is a risk factor for skin cancer, and antidiabetic drugs may reduce skin cancer risk. Nevertheless, the findings remain ambiguous. This Mendelian randomization (MR) study aimed to investigate the causal association of T2D with skin cancer and evaluate the potential impact of antidiabetic drug targets on skin cancer.

Integrated Analysis of Gut Microbiome, Inflammation, and Neuroimaging Features Supports the Role of Microbiome-Gut-Brain Crosstalk in Schizophrenia.

Background And Hypothesis: Gut microbiota has been implicated in the pathogenesis of schizophrenia (SZ) and relevant changes in the brain, but the underlying mechanism remains elusive. This study aims to investigate the microbiota-gut-brain crosstalk centered on peripheral inflammation in SZ patients.

Study Design: We recruited a cohort of 182 SZ patients and 120 healthy controls (HC).

Li-Ions Pre-intercalation Strategy of Manganese Oxides for Capacitive Deionization-Based Selective Lithium Extraction From Low-grade Brine.

In this work, Li preintercalated λ-LiMnO with tunable lithium content is synthesized, which exhibited excellent electrochemical performance and dual-mode electrochemical storage behavior. Double-layer capacitive and diffusion-controlled Faradaic processes play a role in the charge-discharge process, leading to an enhanced lithium selective adsorption capacity. When employed in hybrid capacitive deionization (HCDI), the λ-LiMnO obtains a Li adsorption capacity of 33.

Control of dual-channel optical bistability in a carbon nanotube nanoresonator coupled with a metallic nanoshell.

We theoretically present a flexible method to obtain dual-channel optical bistability (OB) in a coupled system consisting of a metallic nanoshell (MNS) and a carbon nanotube (CNT) nanomechanical resonator (NR) beyond the dipole approximation. The MNS is made of a metallic core and a dielectric shell. The results show that, the four-wave mixing signal is suppressed significantly due to multipole polarizations in comparison to that in the dipole approximation.

Dual-channel bistability modulation in a bilayer graphene-based optomechanical system.

We propose a flexible scheme for studying linear absorption response and optical bistability (OB) in a bilayer graphene-based optomechanical system. The results show that as the coupling between the G-mode phonon and excitons is turned on, the linear absorption spectrum will evolve from a single-peaked structure to a two-peaked one, and the spacing between two splitting peaks is equal to twice as large as the phonon-exciton coupling strength. Especially, we plot bistability phase diagrams within the system's parameter subspaces, demonstrating that the bistable switch can be controlled via no, single, or dual-channel by changing the intensity of the pump light in a weak phonon-exciton coupling regime.

Multifunctional nanoplatform with near-infrared triggered nitric-oxide release for enhanced tumor ferroptosis.

Ferroptosis has emerged as a promising strategy for cancer treatment. Nevertheless, the efficiency of ferroptosis-mediated therapy remains a challenge due to high glutathione (GSH) levels and insufficient endogenous hydrogen peroxide in the tumor microenvironment. Herein, we presented a nitric-oxide (NO) boost-GSH depletion strategy for enhanced ferroptosis therapy through a multifunctional nanoplatform with near-infrared (NIR) triggered NO release.
