NK3-4 regulates the transcription of growth-related and stress resistance-related genes in rice.

NK3-4 is a plant growth-promoting rhizobacterium. In this study, the effects of NK3-4 on rice growth and gene transcription were determined. The results indicated that a seed soaking treatment and a pre-germination seed treatment using NK3-4 promoted rice growth, especially spraying rice seedlings with NK3-4 increased the root number and root length by 34.

Study on the Mechanism of Astragalus Polysaccharides on Cervical Cancer Based on Network Pharmacology.

Background: Astragalus polysaccharides (APS) is a natural phytochemical which has been extensively utilized for anti-tumor therapy over the past few years. However, its impact on cervical cancer (CC) has rarely been studied.

Objective: To clarify the exact mechanism of anti-cancer effects of Astragalus polysaccharides (APS) on Cervical Cancer (CC), we screened differentially expressed genes (DEGs) from The Cancer Genome Atlas (TCGA) to construct the cancer network.

[Realization and Clinical Study of Robotic Technology in Cardiovascular Interventional Surgery].

The high incidence of cardiovascular diseases is a serious threat to human health, and endovascular surgery has become the standard treatment for most interventional cardiovascular diseases. The robotassisted endovascular surgery system further enhances surgeons' ability to perform minimally invasive endovascular procedures in interventional cardiology. This study presents a new robotic technique for coronary intervention from the perspective of clinical application.

Protein Elicitor EsxA Induces Resistance to Seedling Blight and PR Genes Differential Transcription in Rice.

Protein elicitors can induce plant systemic resistance to pathogens. In an earlier study, we cloned an EsxA gene from the plant growth-promoting rhizobacterium Paenibacillus terrae NK3-4 and expressed it in Pichia pastoris. In addition to being important for the pathogenicity of animal pathogens, EsxA can also induce an immune response in animals.

Cloning and expression of the EsxA gene and the growth-promoting effects of the encoded protein on rice seedlings.

An EsxA-encoding gene (esxA) was previously identified in the genome of the plant growth-promoting rhizobacterium Paenibacillus terrae strain NK3-4. The esxA was cloned and expressed in Pichia pastoris, after which the effects of the EsxA protein on rice seedling growth were analyzed to determine whether EsxA contributes to the plant growth-promoting activity of strain NK3-4. The esxA was successfully cloned from the NK3-4 genome and ligated to the eukaryotic expression vector pPICZαA.

Fluoroscopic Stenting as a Bridge to Surgery Emergency Management for Malignant Obstruction of the Colon.

Aim: To investigate the feasibility of a SEMS (self-expandable metallic stent) as a bridge to surgery for malignant colonic obstruction.

Methods: We retrospectively reviewed 83 patients that were in accordance with inclusion criteria; of these, 33 patients that underwent fluoroscopy-guided SEMS placement followed by elective curative resection were classified as a SEMS group and 50 patients, who received emergency surgery (ES), were classified as an ES group. The clinicopathological characteristics, surgery-related parameters, complications, and three-year survival rate were compared between the two groups.

Draft genome sequence, disease-resistance genes, and phenotype of a Paenibacillus terrae strain (NK3-4) with the potential to control plant diseases.

Paenibacillus terrae NK3-4 is a plant growth-promoting rhizobacterium that may be useful for controlling plant diseases. We conducted a genomic analysis and identified the genes mediating antimicrobial functions. Additionally, an extracellular antifungal protein component was isolated and identified.

Preoperative albumin/globulin ratio is a potential prognosis predicting biomarker in patients with resectable gastric cancer.

Background/aims: To investigate the prognostic significance of preoperative albumin to globulin ratio (AGR) in patients with resectable gastric cancer (GC).

Materials And Methods: According to the inclusion criteria, 269 GC patients (male:female=127:67; median age: 67 years) with a stage I through III who underwent gastrectomy with D2 lymphadenectomy and R0 resection were included. These patients were categorized into two groups, namely low AGR group and high AGR group, based on a cutoff point that was obtained using a receiver-operating characteristic curve.

AKAP95 promotes cell cycle progression via interactions with cyclin E and low molecular weight cyclin E.

AKAP95 in lung cancer tissues showed higher expression than in paracancerous tissues. AKAP95 can bind with cyclin D and cyclin E during G1/S cell cycle transition, but its molecular mechanisms remain unclear. To identify the mechanism of AKAP95 in cell cycle progression, we performed AKAP95 transfection and silencing in A549 cells, examined AKAP95, cyclin E1 and cyclin E2 expression, and the interactions of AKAP95 with cyclins E1 and E2.

Mesorectum localization as a special kind of rectal metastasis from breast cancer.

Breast cancer can metastasize to other organs following initial treatment. Bones, liver, and the lung are the most common sites of breast cancer metastases. The digestive tract, on the other hand, is rarely involved.

[Relationship between AKAP95, cyclin E1, cyclin D1, and clinicopathological parameters in lung cancer tissue].

Objective: To investigate the correlation between expression of A-kinase anchoring protein 95 (AKAP95) and protein expression of cyclin E1 and cyclin D1 in lung cancer tissue.

Methods: Fifty-one cases of lung cancer were included in the study. The protein expression of AKAP95, cyclin E1, and cyclin D1 were measured by immunohistochemistry.

Urinary bladder malignant paraganglioma with vertebral metastasis: a case report with literature review.

Paraganglioma is a rare neuroendocrine neoplasm observed in patients of all ages, with an estimated incidence of 3/1,000,000 population. It has long been recognized that some cases are familial. The majority of these tumors are benign, and the only absolute criterion for malignancy is the presence of metastases at sites where chromaffin tissue is not usually found.

[Expression of connective tissue growth factor and pathological remodeling in ascending thoracic aortic aneurysm].

Objective: To study the expression of connective tissue growth factor (CTGF) and its significance in sporadic ascending thoracic aortic aneurysm (AAA), and initially to investigate the mechanisms of pathological remodeling in AAA.

Methods: AAA specimens were taken from 18 patients during elective surgical intervention, and 18 control specimens of ascending aorta were obtained from patients undergoing coronary artery bypass surgery. Specimens were stained with HE and Masson to evaluate the arrangement and aggregation of cells and collagen types I and III; immunohistochemistry staining was performed using antibodies directed against markers of CTGF; real-time PCR analysis was performed to quantify the expression level of CTGF and collagen types I and III.
