The shear strength of a steel shear wall (SSW) is typically governed by the yield strength of the steel. However, changes in mechanical properties beyond yielding—particularly those related to steel hardening and the effects of gravity loads—are not yet fully understood. These factors are critical f...

Abstract: General combining abilities (GCAs) are very important in utilization of heterosis in maize breeding. However, its genetic basis is unclear. In the present study, a set of 118 doubled haploid (DH) lines were induced from F1 generations produced from the cross between the inbred line Zheng 5...

Green manure effectively improves soil nutrients and crop yields, yet its partial substitution for chemical nitrogen fertilizer (CF) in maize systems remains underexplored in ecologically fragile Karst landscapes. To assess the effect of alfalfa green manure on maize yield, soil nutrients, enzymes,...

Linoleate isomerase gene was amplified by PCR from chromosome of Lactobacillus reuteri PYR8, then the gene was cloned into Pichia pastoris expression vector pPIC9K. The recombinant plasmid pPIC9K-LI was transformed into P. pastoris GS115 by electroporation and was induced with 1% methanol, it was de...

Objective: Recurrent or locally advanced head and neck squamous cell carcinoma (HNSCC) carry a poor prognosis due to its aggressive invasiveness and resistance to conventional chemotherapy. Identifying effective biomarkers for early detection and prognostic assessment is crucial to enhance treatment...

Repairing and regenerating tissue barriers is a key challenge in regenerative medicine. Stem cells play a crucial role in restoring the structural and functional integrity of key epithelial barrier surfaces, including the skin and mucosa. This review analyzes the role of dental pulp stem cells (DPSC...

In the past few decades, apoptosis has been regarded as the only form of programmed cell death. However, the traditional view has been challenged by the identification of several forms of regulated necrosis, including necroptosis. Necroptosis is typified by a necrotic cell death morphology and is co...

The bacterial brown spot disease (BBS), caused primarily by Pseudomonas syringae pv. syringae van Hall (Pss), reduces plant vigor, yield and quality in maize. To reveal the nature of the defense mechanisms and identify genes involved in the effective host resistance, the dynamic changes of defense t...

Ascorbate peroxidase (APX) plays a key role in scavenging reactive oxygen species (ROS) in higher plants. However, there is very little information available on the APXs in kiwifruit (Actinidia), which is an economically and nutritionally important horticultural crop with exceptionally high ascorbic...

Chemosensory proteins (CSPs) perform several functions in insects. This study performed the gene expression, ligand-binding, and molecular docking assays on the EforCSP3 identified in the parasitoid wasp Encarsia formosa, to determine whether EforCSP3 functions in olfaction, especially in host locat...

Cancer is a disease with abnormally proliferating cells and therefore proliferation rate is an important index for assessing tumour growth. Ki-67 is a commonly used proliferation marker considered to be an unfavourable prognostic marker in some tumors, while Thymidine kinase 1 (TK1) is an interestin...

Since its discovery a decade ago, microRNA has been identified as one of the major regulatory gene families in eukaryotic cells. Many functions of microRNAs have been revealed both in flora and fauna in recent years, but the transcriptional regulation of microRNA genes is not well-understood. In the...
