[Generational differences in overweight and obesity among Chinese adult resident].

Objective: To analyze the generational differences in overweight/obesity prevalence and central obesity prevalence among Chinese adult residents aged 20 years and above at the same ages.

Methods: A total of 38 908 healthy adult residents aged 20 years and above from "the China Health and Nutrition Survey" in 1991, 2000, 2009, and 2018 were selected for this study. Based on age at the time of the survey, the study subjects were divided into 6 age groups(20-29, 30-39, 40-49, 50-59, 60-69, and ≥70 years old) corresponding to 9 different generations of births in 10, 20, 30, 40, 50, 60, 70, 80, and 90 generations, respectively.

Using molecular characteristics to distinguish multiple primary lung cancers and intrapulmonary metastases.

Objectives: Multiple lung cancers may present as multiple primary lung cancers (MPLC) or intrapulmonary metastasis (IPM) with variations in clinical stage, treatment, and prognosis. However, the existing differentiation criteria based on histology do not fully meet the clinical needs. Next-generation sequencing (NGS) may play an important role in assisting the identification of different pathologies.

Auto-inhibition and activation of a short Argonaute-associated TIR-APAZ defense system.

Short prokaryotic Ago accounts for most prokaryotic Argonaute proteins (pAgos) and is involved in defending bacteria against invading nucleic acids. Short pAgo associated with TIR-APAZ (SPARTA) has been shown to oligomerize and deplete NAD upon guide-mediated target DNA recognition. However, the molecular basis of SPARTA inhibition and activation remains unknown.

Generational Differences in Food Consumption among Chinese Adults of Different Ages.

Limited knowledge currently exists regarding the dynamics of generational shifts in food consumption among adult residents in China. This study aimed to investigate the generational differences in dietary status among different generations of Chinese adult residents aged 20 years and older. Survey participants from four waves (1991, 2000, 2009, and 2018) of the China Health and Nutrition Survey (CHNS) cohort were included in the study (N = 40,704), providing three-day 24 h dietary data.

Mammalian trans-editing factor ProX is able to deacylate tRNA mischarged with alanine.

The precise coupling of tRNAs with their cognate amino acids, known as tRNA aminoacylation, is a stringently regulated process that governs translation fidelity. To ensure fidelity, organisms deploy multiple layers of editing mechanisms to correct mischarged tRNAs. Prior investigations have unveiled the propensity of eukaryotic AlaRS to erroneously attach alanine onto tRNA and tRNA featuring the G4:U69 base pair.

Personalized circulating tumor DNA detection to monitor immunotherapy efficacy and predict outcome in locally advanced or metastatic non-small cell lung cancer.

Objective: Immune checkpoint inhibitors (ICIs) or combined with chemotherapy exhibit substantial efficacy for the treatment of advanced non-small cell lung cancer (NSCLC). However, reliable biomarkers that can monitor response to first-line ICIs ± chemotherapy remain unclear.

Methods: A total of 16 tumor tissues and 46 matched peripheral blood samples at baseline and during treatment were retrospectively collected from 19 locally advanced or metastatic NSCLC patients.

Differences in DNA damage repair gene mutations between left- and right-sided colorectal cancer.

Background: Colorectal cancer (CRC) is the third leading cause of cancer-related deaths worldwide. Studies have shown that the DNA damage response (DDR) mutation is strongly associated with microsatellite instability (MSI) status and is an indication for patients with CRCs receiving immune checkpoint inhibitor (ICI) treatment. However, DDR mutation in microsatellite stable (MSS) CRC remains unclear.

Phloretin decreases microglia-mediated synaptic engulfment to prevent chronic mild stress-induced depression-like behaviors in the mPFC.

Stress is an important risk factor to induce psychiatric disorders such as depression. Phloretin (PHL), a natural dihydrochalcone compound, has been shown to exhibit anti-inflammatory and anti-oxidative effects. However, the impact of PHL on the depression and the underlying mechanism remain unclear.

Case report: Long-term clinical benefit of pyrotinib therapy following trastuzumab resistance in -amplification recurrent mucinous ovarian carcinoma.

Advanced or recurrent mucinous carcinoma of the ovary minimally responds to current cytotoxic treatments and has a poor prognosis. Despite multimodal treatment with chemotherapy and surgery, most patients ultimately progress and require palliative systemic therapy. Anti-HER2 therapy has been demonstrated to be an effective strategy for the treatment of HER2-positive breast cancer.

Pathological complete remission in ALK-positive lung cancer patient after multiple lines of conversion therapy.

Introduction: Traditional therapeutic approaches for the treatment of advanced non-small-cell lung cancer (NSCLC) are based on chemotherapy. However, the discovery and understanding of oncogenic driver alterations has led to the development of targeted therapies that have substantially improved patient outcomes. Still, to date, there have been no reports of patients with advanced anaplastic lymphoma kinase (ALK)-positive lung cancer achieving clinical complete response (cCR) in the systemic lesion and pathological complete remission (pCR) in primary lung lesion after multiple lines of conversion therapy.

Genomic and clinicopathological features of lung adenocarcinomas with micropapillary component.

Background: Lung adenocarcinoma (LA) with a micropapillary component (LAMPC) is a histological subtype of lung cancer that has received increasing attention due to its correlation with poor prognosis, and its tendency to recur and metastasize. At present, comprehensive genomic profiles and clinicopathological features for LAMPC remain unclear and require further investigation.

Methods: From September 2009 to October 2020, a total of 465 LAMPC patients were recruited and divided into four groups according to MPC proportions, and the correlations between varying proportions of MPCs and clinicopathological characteristics were analyzed.

Comprehensive analyses of genomic features and mutational signatures in adenosquamous carcinoma of the lung.

Adenosquamous carcinoma (ASC) of the lung is a relatively rare tumor with strong aggressiveness and poor prognosis. The analysis of mutational signatures is becoming routine in cancer genomics and has implications for pathogenesis, classification, and prognosis. However, the distribution of mutational signatures in ASC patients has not been evaluated.

Case Report: Durable partial response to icotinib plus crizotinib in a lung adenocarcinoma patient with double uncommon G719D/L861Q mutations and an acquired novel - fusion.

Non-small cell lung cancer (NSCLC) patients harboring exon 14 skipping or high amplification display a high rate of response to MET inhibitors. However, fusions in NSCLC have rarely been revealed. In this report, a 63-year-old woman with lung adenocarcinoma (LADC), harboring exon 18 G719D and exon 21 L861Q mutations, received first-generation, -tyrosine kinase inhibitor (TKI) icotinib therapy.

Genomic Features of Organ-Specific Metastases in Lung Adenocarcinoma.

Background: The genomic features of cancer cells may confer the metastatic ability of lung adenocarcinoma (LUAD) to metastasize to specific organs. We aimed to identify the differences in genomic alterations between patients with primary LUAD with and without metastases and to elucidate the metastatic biology that may help developing biomarker-directed therapies for advanced or metastatic disease.

Methods: A retrospective cohort of 497 patients with LUAD including 388 primary tumors (PR), 53 bone metastases (MT-bone), 30 liver metastases (MT-liver), and 26 brain metastases (MT-brain) was tested for genomic alterations by a next-generation sequencing assay.

Wheat leaf area index prediction using data fusion based on high-resolution unmanned aerial vehicle imagery.

Background: Leaf Area Index (LAI) is half of the amount of leaf area per unit horizontal ground surface area. Consequently, accurate vegetation extraction in remote sensing imagery is critical for LAI estimation. However, most studies do not fully exploit the advantages of Unmanned Aerial Vehicle (UAV) imagery with high spatial resolution, such as not removing the background (soil and shadow, etc.

Predicting Best-Selling New Products in a Major Promotion Campaign Through Graph Convolutional Networks.

Before such a promotion, it is important to predict potential best sellers and their respective sales volumes so that the platform can arrange their supply chains and logistics accordingly. For items with a sufficiently long sales history, accurate sales forecast can be achieved through the traditional statistical forecasting techniques.

Case Report: Complete Response of Primary Massive Hepatocellular Carcinoma to Anti-Programmed Death Ligand-1 Antibody Following Progression on Anti-Programmed Death-1 Antibody.

Hepatocellular carcinoma (HCC) is an aggressive liver tumor that occurs due to chronic liver disease, and it has a high mortality rate and limited treatment options. Immune checkpoint inhibitors have been successfully introduced and used in cancer therapy, among which inhibitors of programmed death ligand-1 (PD-L1) and its receptor programmed death-1 (PD-1) are commonly administered for HCC as combination therapy, including combined anti-angiogenic and immunotherapy combination therapy. We report a case of a primary massive HCC patient with portal hepatic vein tumor thrombus who had a good response to atezolizumab in combination with bevacizumab, following progression of disease on combined immunotherapy with pembrolizumab and lenvatinib.

Zinc oxide nanoparticle-triggered oxidative stress and autophagy activation in human tenon fibroblasts.

Glaucoma is a leading cause of irreversible blindness worldwide due to elevated intraocular pressure, and filtering surgery can efficiently control intraocular pressure of glaucoma patients. However, failure of filtering surgery commonly results from scarring formation at the surgical site, in which fibroblast proliferation plays an essential role in the scarring process. Our previous study has demonstrated that zinc oxide (ZnO) nanoparticles could efficiently inhibit human tenon fibroblasts (HTFs) proliferation.

Topological origin of phase separation in hydrated gels.

Hypothesis: Depending on their composition, hydrated gels can be homogeneous or phase-separated, which, in turn, affects their dynamical and mechanical properties. However, the nature of the structural features, if any, that govern the propensity for a given gel to phase-separate remains largely unknown. Here, we argue that the propensity for hydrated gels to phase-separate is topological in nature.

A new expansion material used for roof-contacted filling based on smelting slag.

The improper handling of smelting slag will seriously pollute the environment, and the unfilled roof of the goaf of the mine will threaten the safety of the mine. Expansion materials have attracted more and more attention because of their excellent properties. In this paper, copper-nickel smelting slag that has some active ingredients of gelling is used instead of traditional aggregate and some part of cement in order to reduce its pollution to the environment and its costs.
