Several quantitative trait genes (QTGs) related to rice heading date, a key factor for crop development and yield, have been identified, along with complex interactions among genes. However, a comprehensive genetic interaction network for these QTGs has not yet been established. In this study, we use 18K-rice lines to identify QTGs and their epistatic interactions affecting rice heading date.

Background: Surgical palliative surgery is a common method for treating patients with middle and late stage gastrointestinal tumors. However, these patients generally experience high levels of cancer pain, which can in turn stimulate the body's stress and undermine the effect of external surgery. Although opioid drugs have a significantly positive effect on controlling cancer pain, they can induce adverse drug reactions and potential damage to the body 's immune function.

Intrathyroid thymic carcinoma(ITTC) is a rare thyroid tumor that lacks typical clinical manifestations and imaging features, making preoperative diagnosis challenging.The primary treatment for ITTC is radical surgery; however, the effectiveness of adjuvant radiotherapy and chemotherapy post-surgery is not well-established. This paper presents a case of ITTC , analyzing the clinical data and correlating it with the literature to explore the clinical manifestations, diagnostic approach, treatment, and prognosis of ITTC.

Contrast-enhanced spectral CT can synthesize true contrast-enhanced (TCE) images and virtual noncontrast (VNC) images in a single scan without geometric misalignment. To improve work efficiency and reduce patients' imaging dose, we studied the feasibility of using VNC images for radiotherapy treatment planning, with true noncontrast (TNC) images as references and explored its dosimetric advantages compared to using TCE images.

Here, two sets of reactions were conducted using cerium nitrate and HO-oxidized cerium nitrate, resulting in the formation of two distinct mixed-valent CeOCs [Ce Ce O(OH)(PhCO)(DMF)] (Ce) and [Ce Ce O(OH)(PhCO)(DMF)] (Ce). These two clusters exhibit different structures and Ce(III)/Ce(IV) ratios, demonstrating the critical role of cerium oxidation states and the occurrence of redox reactions in cluster formation.

The research findings indicated that CrO demonstrated superior structural integrity at corrosion temperatures of both 600 °C and 700 °C and displayed exceptional resistance to LBE corrosion. ZrO demonstrates resistance to LBE infiltration.

Water treatment and seawater desalination are two areas in which nanofiltration (NF) membranes have gained significant attention. The permeability and contamination resistance of NF membranes are crucial for their application in ion separation. Herein, a zwitterion monomeric -sulfobutylpiperazine (PIPBS) was designed and synthesized through an in situ ring-opening reaction between 1,4-butylsulfonic acid lactone and piperazine.

However, few studies have projected the carbon sink trends in regions where ecological engineering projects overlap and have not considered the different climate change conditions and land use scenarios. Using the ensemble empirical mode decomposition method and machine learning algorithms (enhanced boosted regression trees), the aims of this study to elucidate the stability of carbon sinks and their driving mechanisms in areas where ecological projects overlap and to predict the potential enhancement in carbon sinks under varying climate and human activity scenarios.

However, a major challenge in hybrid breeding is selecting desirable combinations from a vast pool of potential crosses. Genomic selection (GS) has emerged as a powerful tool to tackle this challenge, but its success in practical breeding depends on prediction accuracy.

Rapid climate oscillations potentially lead to species geographic range shifts, population declines, and even extinctions. The rare and endangered species, being critical components of regional biodiversity, hold the key to understanding local adaptation and evolutionary processes shaping species distributions.
