Bananas are economically important crops valued for both their nutritional and dietary uses. However, the global banana industry suffers from a narrow base dominated by a single variety. Developing novel varieties enriched in health-promoting compounds such as betalains can help diversify banana germplasm and meet evolving consumer demands.

Purpose: Peripheral nerve blocks are an important part of postoperative analgesia for the extremities. Previously, we reported that a single shot of 0.375% ropivacaine (20 mL) via ultrasound-guided popliteal sciatic and saphenous nerve blocks provided satisfactory analgesia after foot and ankle surgery; however, toe and ankle weakness in the early postoperative period became a concern for patients.

Neuroendocrine neoplasms (NENs) are a group of highly heterogeneous neoplasms originating from neuroendocrine cells with a gradually increased incidence. Metabolic change is one of the recognized markers of tumor progression, which has been extensively and systematically studied in other malignant tumors. However, metabolic change in NENs has been relatively poorly studied, and systematic reviews are lacking.

Currently, understanding of how banana cultivars differ in metabolism during ripening is limited. This study compared the pulp metabolites of six banana cultivars using NMR. Bananas with B genome were found to have higher amounts of total starch, amylose, amylopectin, and resistant starch compared to those without B genome.

N6-methyladenosine (m6A) is considered the most prevalent RNA epigenetic regulator in cancer. FTO, an m6A demethylase, has been implicated in contributing to the progression of various cancers by up-regulating the expression of multiple oncogenes. However, studies exploring its impact on lipid metabolism in cancer, especially in pNENs, remain scarce.

Unlabelled: Previous studies illustrated that two banana GA20 oxidase2 (MaGA20ox2) genes, and , are implicated in controlling banana growth and development; however, the biological function of each gene remains unknown. Ma04g15900 protein (termed MaGA20ox2f in this article) is the closest homolog to the Rice SD1 (encoded by 'green revolution gene', ) in the banana genome. The expression of is confined to leaves, peduncles, fruit peels, and pulp.

Recognizing ripe tomatoes is a crucial aspect of tomato picking. To ensure the accuracy of inspection results, You Only Look Once version 9 (YOLOv9) has been explored as a fruit detection algorithm. To tackle the challenge of identifying tomatoes and the low accuracy of small object detection in complex environments, we propose a ripe tomato recognition algorithm based on an enhanced YOLOv9-C model.

Hypoxia has been highly proven a hallmark of tumor micro-environment, promoting the malignant phenotypes, playing a crucial role from tumor initiation, progression, invasion, and intravasation to metastatic dissemination and outgrowth. Increasing evidence also showed that hypoxia mediated the abnormal lipid metabolism in cancer by regulating various oncogenic signal pathways. However, it is still unclear but attractive how hypoxia specifically functioned and changed the condition of the tumor micro-environment.

The study aimed at analyzing the therapeutic effect of salmon calcitonin on patients with lumbar spine fracture after operation. Eighty-eight cases with lumbar spine fracture who underwent percutaneous vertebroplasty (PVP) in The Huichang People's Hospital from February 2020 to February 2023 were separated into two groups. The 44 cases in the control group were treated with calcium carbonate and Vitamin D3 tablets, on the basis, the salmon calcitonin was applied to treat the 44 cases in study group.

The trihelix transcription factor (GT) gene family members play vital roles in plant growth and development, responses to abiotic or biotic stress, and fruit ripening. However, its role in banana fruit ripening remains unclear. Here, 59 MaGT gene members were identified in banana and clustered into five subfamilies, namely GT1, GT2, GTγ, SIP1, and SH4.

Background: Pancreatic neuroendocrine neoplasm (pNEN) poses significant challenges in clinical management due to their heterogeneity and limited treatment options. In this study, we investigated the potential of simvastatin (SIM) as an anti-tumor agent in pNEN.

Methods: We conducted cell culture experiments using QGP-1 and BON-1 cell lines and assessed cell viability, proliferation, migration, and invasion following SIM treatment.

Landfilled metallurgical residues are valuable raw materials for the recovery of strategic vanadium resources. However, efficient separation of vanadium from these residues is challenging due to its strong oxidation resistance and coating within silicate inclusions. To address this issue, this study proposes an enhanced leaching process utilizing the synergistic effect of O-catalyzed ultrasonic field in a low concentration sulfuric acid system.

  • * Exosomal miR-4488, which is overexpressed in hypoxic pNEN cells, influences macrophage behavior by promoting M2 polarization and suppressing the protein RTN3, which in turn impacts fatty acid oxidation and the PI3K/AKT/mTOR signaling pathway.
  • * M2 polarized macrophages enhance pNEN metastasis by releasing MMP2, creating a feedback loop involving miR-4488, RT

An inexpensive and high-performing solid Coumarone resin was added to Styrene-butadiene-styrene (SBS) copolymer-modified asphalt to enhance its storage stability and road performance. To assess the effect of Coumarone resin dosage on the SBS-modified asphalt, a series of laboratory tests were conducted. The composite modified asphalt's segregation test was used to evaluate its storage stability, Dynamic Shear Rheometer (DSR) and Multiple Stress Creep Recovery (MSCR) tests were employed to investigate its high-temperature performance and permanent deformation resistance, and the Bending Beam Rheology (BBR) test was utilized to measure its low-temperature performance.

The homoterpenes (3)-4,8-dimethyl-1,3,7-nonatriene (DMNT) and (,)-4,8,12-trimethyl-1,3,7,11-tridecatetraene (TMTT) are the major herbivore-induced plant volatiles that help in defense directly by acting as repellants and indirectly by recruiting insects' natural enemies. In this study, DMNT and TMTT were confirmed to be emitted from citrus () leaves infested with Asian citrus psyllid ( Kuwayama; ACP), and two cytochrome P450 (CYP) genes ( and ) were newly identified and characterized. Understanding the functions of these genes in citrus defense will help plan strategies to manage huanglongbing caused by Liberibacter asiaticus (Las) and spread by ACP.
