A colorectal cancer (CRC) mouse model was built with a total of 50 C57BL/6J mice that were induced by administrating AOM/DSS. These experimental animals were split up into 5 groups, a control group, a model group, and low-, medium- and high-dose Chinese herbal compound groups.

Blocking methionine catabolism induces senescence and confers vulnerability to GSK3 inhibition in liver cancer.

Availability of the essential amino acid methionine affects cellular metabolism and growth, and dietary methionine restriction has been implicated as a cancer therapeutic strategy. Nevertheless, how liver cancer cells respond to methionine deprivation and underlying mechanisms remain unclear. Here we find that human liver cancer cells undergo irreversible cell cycle arrest upon methionine deprivation in vitro.

The application of strategy based on LSTM for the short-term prediction of PM in city.

Many cities have long suffered from the events of fine particulate matter (PM) pollutions. The Taiwanese Government has long strived to accurately predict the short-term hourly concentration of PM for the warnings on air pollution. Long Short-Term Memory neural network (LSTM) based on deep learning improves the prediction accuracy of daily PM concentration but PM prediction for next hours still needs to be improved.

Background: Dementia is more prevalent in women than in men across the world, and sex differences are reflected in the burden of dementia borne by women and men. However, a few studies have specifically analyzed the disease burden of dementia in Chinese women.

Objective: This article aims to raise awareness of Chinese females with dementia (CFWD), outline an effective response to future trends in China from a female perspective, and provide a reference for the scientific formulation of dementia prevention and treatment policies in China.

Contamination and Health Risk Assessment of Polycyclic Aromatic Hydrocarbons in Seasoning Flour Products in Hunan, China.

Polycyclic aromatic hydrocarbons (PAHs) are persistent organic pollutants with carcinogenic, teratogenic, and mutagenic effects. Dietary intake is one of the significant exposure pathways of PAHs. In this study, gas chromatography-triple quadrupole mass spectrometry (GC-MS/MS) was used to detect 16 priority PAHs listed by the United States Environmental Protection Agency (USEPA) in seasoning flour products distributed in Hunan Province.

Case Report: Severe rash/desquamation induced by sorafenib in an uHCC patient and its clinical management.

Sorafenib-related dermatological toxicity is a well-known adverse reaction that can severely affect therapeutic outcomes. Rash/desquamation with its variable manifestations is one of the common clinical presentations. Currently, no standard continuum of care for sorafenib-related rash/desquamation has been established.

ADAR1 downregulation by autophagy drives senescence independently of RNA editing by enhancing p16 levels.

Cellular senescence plays a causal role in ageing and, in mice, depletion of p16-expressing senescent cells delays ageing-associated disorders. Adenosine deaminases acting on RNA (ADARs) are RNA-editing enzymes that are also implicated as important regulators of human ageing, and ADAR inactivation causes age-associated pathologies such as neurodegeneration in model organisms. However, the role, if any, of ADARs in cellular senescence is unknown.

The Jarvik 2000 Left Ventricular Assist Device: Results of the United States Bridge to Transplant Trial.

The Jarvik 2000 bridge to transplant investigational device exemption study was a multicentered, prospective study of 150 UNOS status I patients implanted with the Jarvik 2000 between 2005 and 2012. During the study period, there were numerous modifications of the system that included converting from pin to cone bearings. Results were analyzed for three cohorts: total (n = 150), pin (n = 128), and cone (n = 22).

Identification of environmental microorganism using optimally fine-tuned convolutional neural network.

To not only optimize the hyper-parameters of the classification layer of dense convolutional network with 201 convolutional layers (DenseNet-201) but also use data augmentation processes could enhance the performance of DenseNet-201, and DenseNet-201 is rarely applied to the identifications of the environmental microorganism (EM) images. Hence, this study was to propose the optimally fine-tuned DenseNet-201 (OFTD) with data augmentation to better classify the EM images on Environmental Microorganism Dataset (EMDS). The training dataset was composed of 70% Environmental Microorganism Dataset (EMDS) images and so was mainly used to fit the parameters of convolutional layers of optimally fine-tuned DenseNet-201 (OFTD).

Somatic Mutation Analysis in Salix suchowensis Reveals Early-Segregated Cell Lineages.

Long-lived plants face the challenge of ever-increasing mutational burden across their long lifespan. Early sequestration of meristematic stem cells is supposed to efficiently slow down this process, but direct measurement of somatic mutations that accompanies segregated cell lineages in plants is still rare. Here, we tracked somatic mutations in 33 leaves and 22 adventitious roots from 22 stem-cuttings across eight major branches of a shrub willow (Salix suchowensis).

mA-independent genome-wide METTL3 and METTL14 redistribution drives the senescence-associated secretory phenotype.

Methyltransferase-like 3 (METTL3) and 14 (METTL14) are core subunits of the methyltransferase complex that catalyses messenger RNA N-methyladenosine (mA) modification. Despite the expanding list of mA-dependent functions of the methyltransferase complex, the mA-independent function of the METTL3 and METTL14 complex remains poorly understood. Here we show that genome-wide redistribution of METTL3 and METTL14 transcriptionally drives the senescence-associated secretory phenotype (SASP) in an mA-independent manner.

Objective: To use a randomized, prospective, multi-institutional study to compare the safety and efficacy of conventional insufflation (CIS) and valveless insufflation (AirSeal Insufflation - AIS) at the conventional pressure of 15 mm Hg in robot-assisted partial nephrectomy - a surgery where AIS has gained popularity for maintaining visualization despite suction. This study was also powered to evaluate the effect of decreasing pneumoperitoneum by 20% in the valveless system.

Materials And Methods: Three high-volume institutions randomized subjects into CIS 15, AIS 15, and AIS 12 mm Hg cohorts.

ARID2 Deficiency Correlates with the Response to Immune Checkpoint Blockade in Melanoma.

The SWI/SNF chromatin remodeler family includes the BAF and PBAF complexes. ARID2, encoding a PBAF complex subunit, is frequently mutated in melanoma independently of BRAF/RAS mutations. Emerging evidence shows that SWI/SNF complexes regulate tumor immunity; for instance, the loss of PBRM1, another PBAF complex subunit, enhances susceptibility to immune checkpoint inhibitors in melanoma.

One-Year Echocardiographic, Functional, and Quality of Life Outcomes After Ultrasound-Facilitated Catheter-Based Fibrinolysis for Pulmonary Embolism.

Background: Accelerated tPA (tissue-type plasminogen activator) dosing regimens for ultrasound-facilitated, catheter-directed fibrinolysis improve short-term computed tomographic-measured right ventricular (RV)-to-left ventricular diameter ratio in massive and submassive pulmonary embolism. The impact on RV remodeling, functional status, and quality of life over the long-term remains unclear.

Methods: To study 1-year changes in RV remodeling, functional status, and quality of life, we assessed patients with acute submassive pulmonary embolism randomly assigned to 1 of 4 tPA dosing regimens for ultrasound-facilitated, catheter-directed fibrinolysis in the OPTALYSE-PE trial (Optimum Duration and Dose of r-tPA With the Acoustic Pulse Thrombolysis Procedure for Intermediate-Risk Pulmonary Embolism; 8 mg/2 hours, 8 mg/4 hours, 12 mg/6 hours, and 24 mg/6 hours).

Predictors of Treatment Response Following Ultrasound-Facilitated Catheter-Directed Thrombolysis for Submassive and Massive Pulmonary Embolism: A SEATTLE II Substudy.

Background: Little is known about which factors predict improvement in clinical and imaging parameters among patients undergoing catheter-directed thrombolysis for submassive or massive pulmonary embolism. The identification of such predictors may allow for more appropriate patient selection for ultrasound-facilitated catheter-directed thrombolysis.

Methods: We conducted a retrospective cohort analysis of patients from the SEATTLE II trial (Prospective, Single-Arm, Multi-Center Trial of EkoSonic Endovascular System and Activase for Treatment of Acute Pulmonary Embolism) to identify clinical characteristics that independently predict pulmonary artery pressures, right ventricular-to-left ventricular (RV/LV) diameter ratio, and modified Miller angiographic index following ultrasound-assisted catheter-directed thrombolysis.

Topoisomerase 1 cleavage complex enables pattern recognition and inflammation during senescence.

Cyclic cGMP-AMP synthase (cGAS) is a pattern recognition cytosolic DNA sensor that is essential for cellular senescence. cGAS promotes inflammatory senescence-associated secretory phenotype (SASP) through recognizing cytoplasmic chromatin during senescence. cGAS-mediated inflammation is essential for the antitumor effects of immune checkpoint blockade.

Targeting the untargetable KRAS in cancer therapy.

is one of the most well-known proto-oncogenes. Its gain-of-function mutations occur in approximately 30% of all human cancers. As the most frequently mutated isoform, KRAS is intensively studied in the past years.

N-Methylation of Adenosine of mRNA Contributes to PARP Inhibitor Resistance.

Despite the high initial response rates to PARP inhibitors (PARPi) in -mutated epithelial ovarian cancers (EOC), PARPi resistance remains a major challenge. Chemical modifications of RNAs have emerged as a new layer of epigenetic gene regulation. N-methyladenosine (mA) is the most abundant chemical modification of mRNA, yet the role of mA modification in PARPi resistance has not previously been explored.

Catheter-directed, ultrasound-facilitated fibrinolysis in obese patients with massive and submassive pulmonary embolism.

Obesity is a well-established risk factor for pulmonary embolism (PE). However, treatment of PE in obese patients is challenging because of limited outcomes data, especially with advanced therapies such as catheter-based fibrinolysis. We assessed the efficacy and safety of ultrasound-facilitated, catheter-directed fibrinolysis in obese patients with submassive and massive PE enrolled in the SEATTLE II Trial.

Epigenetic Basis of Cellular Senescence and Its Implications in Aging.

Cellular senescence is a tumor suppressive response that has become recognized as a major contributor of tissue aging. Senescent cells undergo a stable proliferative arrest that protects against neoplastic transformation, but acquire a secretory phenotype that has long-term deleterious effects. Studies are still unraveling the effector mechanisms that underlie these senescence responses with the goal to identify therapeutic interventions.

The CLOSER trial: a multi-center study on the clinical safety and effectiveness of Closer VSS, a novel resorbable transfemoral vascular access sealing system.

Objectives: To evaluate the safety and effectiveness of the Closer Vascular Sealing System (VSS) against prespecified performance goals (PGs) in sealing femoral arterial access following 5-7 Fr procedures.

Background: Inconsistent safety profiles, costs and learning curves of earlier generation vascular closure devices have limited their widespread use following transfemoral procedures.

Methods: In this prospective single-arm, multi-center trial, we compared the clinical outcomes in patients undergoing 5-7 Fr transfemoral diagnostic or interventional procedures and access sites managed with Closer VSS against pre-specified PGs.

Ultrasound-facilitated, catheter-directed, low-dose fibrinolysis in elderly patients with pulmonary embolism: A SEATTLE II sub-analysis.

Elderly patients with acute pulmonary embolism (PE) have higher mortality than non-elderly patients, but receive systemic fibrinolysis less frequently. In this sub-analysis of the SEATTLE II trial, we evaluated the efficacy and safety of ultrasound-facilitated, catheter-directed, low-dose fibrinolysis in elderly patients with submassive and massive PE. We compared patients ⩾65 years old with those <65 years old.

Risk factors for major bleeding in the SEATTLE II trial.

Ultrasound-facilitated, catheter-directed, low-dose fibrinolysis minimizes the risk of intracranial bleeding compared with systemic full-dose fibrinolytic therapy for pulmonary embolism (PE). However, major bleeding is nevertheless a potential complication. We analyzed the 150-patient SEATTLE II trial of submassive and massive PE patients to describe those who suffered major bleeding events following ultrasound-facilitated, catheter-directed, low-dose fibrinolysis and to identify risk factors for bleeding.
