Inflammation and metabolic processes are thought to play significant roles in both the initiation and progression of this disease. This study aimed to clarify the causal relationships between CRC and specific inflammatory proteins, immune cell types, and metabolites, while also exploring potential bidirectional associations and identifying possible therapeutic targets.

Advances and challenges in the treatment of myelodysplastic syndromes.

Myelodysplastic syndromes (MDS) is a heterogeneous group of pre-leukemic diseases characterized by peripheral blood cytopenia, morphologic dysplasia, and an increased risk of transformation to leukemia. MDS develop from genetically mutant clonal hematopoietic stem and progenitor cells (HSPCs) which have defects in generating mature functional blood cells due to impaired differentiation and/or survival activities. In addition, mutant HSPCs also inhibit the generation of new blood cells from remaining healthy HSPCs.

Inhibiting reactive oxygen species production mitigates endoplasmic reticulum damage in florets of developing maize ears under heat stress.

Heat stress is increasingly becoming a major constraint to agricultural production due to global warming and higher probability of extreme events. To mitigate the yield loss caused by heat stress, it is essential to understand the mechanisms underlying its effects on young ear development. In this study, we investigate the impact of heat stress on heat-sensitive and heat-tolerant maize varieties under field conditions.

Humanized L184Q Mutated Surfactant Protein C Gene Alters Alveolar Type 2 Epithelial Cell Fate.

Alveolar type 2 epithelial (AT2) cells synthesize surfactant protein C (SPC) and repair an injured alveolar epithelium. A mutated surfactant protein C gene ( Gene ID: 6440) in newborns has been associated with respiratory distress syndrome and pulmonary fibrosis. However, the underlying mechanisms causing gene mutations to regulate AT2 lineage remain unclear.

Caspase 8 deletion causes infection/inflammation-induced bone marrow failure and MDS-like disease in mice.

Myelodysplastic syndromes (MDS) are a heterogeneous group of pre-leukemic hematopoietic disorders characterized by cytopenia in peripheral blood due to ineffective hematopoiesis and normo- or hypercellularity and morphologic dysplasia in bone marrow (BM). An inflammatory BM microenvironment and programmed cell death of hematopoietic stem/progenitor cells (HSPCs) are thought to be the major causes of ineffective hematopoiesis in MDS. Pyroptosis, apoptosis and necroptosis (collectively, PANoptosis) are observed in BM tissues of MDS patients, suggesting an important role of PANoptosis in MDS pathogenesis.

[Effects of seed grading on population regularity degree and yield of summer maize].

Grading seeds based on grain size is an effective measure to improve population regularity degree and increase the yield of summer maize. Taking Denghai 605 as the experimental material, we set up a field experiment with treatments based on grain size: large seeds (L), medium-round seeds (MR), medium-flat seeds (MF), medium-round and medium-flat mixed seeds (MRF), and small seeds (S), with no-grading seeds as control (CK). We investigated seedling emergence rate, population regularity degree (including height, ear height and stem diameter), seedling sturdiness index, photosynthetic characteristics, dry matter accumulation and distribution characteristics, and yield.

Why is the risk of industrial non-routine activities high and how can it be evaluated? An integrated approach.

Non-routine activities such as startup, shutdown, maintenance, and operation commissioning require increased human interaction with the corresponding process. Owing to operator or procedural violations, the risk of accidents can be high during non-routine activities, even though they are performed less frequently. To identify and evaluate the hazards of non-routine processes, an integrated method combining job hazard analysis (JHA), hazard and operability analysis (HAZOP), and deviation degrees is proposed.

Distinct roles of hematopoietic cytokines in the regulation of leukemia stem cells in murine MLL-AF9 leukemia.

Lymphoid-primed multipotent progenitor (LMPP)-like and granulocyte-monocyte progenitor (GMP)-like leukemia stem cells (LSCs) co-exist in the blood of most patients with acute myeloid leukemia (AML). Complete elimination of both types of LSCs is required to cure AML. Using an MLL-AF9-induced murine AML model, we studied the role of hematopoietic cytokines in the survival of LMPP- and GMP-like LSCs.

Diagnostic accuracy of MUC7 expression for bladder cancer: A systematic review and meta-analysis.

Background: There have been many studies on MUC7 and bladder cancer (BC) that have been published; however, all sample sizes were not enough which led to their conclusions being based on small samples. Therefore, this meta-analysis aims to systematically analyze the diagnostic value of MUC7 for bladder cancer and provide a scientific basis for the diagnosis of bladder cancer.

Methods: To obtain relevant literature on MUC7 diagnosed bladder cancer, databases such as PubMed, Web of Science, Cochrane Library, China National Knowledge Infrastructure, Wanfang data, Chongqing VIP, and Chinese Biomedical Literature Database were searched from the establishment of the database to July 11, 2023.
