Powdery mildew is a common serious disease threatening global melon production. Red light can improve plant resistance to powdery mildew by inducing endogenous ethylene synthesis; however, the underlying molecular mechanism requires elucidation. In this study, an ERF transcription factor CmRAP2-13 was identified, silencing it significantly improved melon seedlings resistance to powdery mildew.

Bitterness, caused by cucurbitacin B (CuB), is one of the important traits that affects melon fruit quality and consumer acceptance. Therefore, the detailed mechanism behind the regulation of CuB biosynthesis on melon fruit needs to be further explored. This study investigated CuB content and transcriptomes of "YMR" melon fruit treated by 5 and 20 mg L CPPU.

Article Synopsis
  • A new definition of cardiovascular health (CVH) was created to assess heart health more effectively, particularly in patients with high blood sugar (hyperglycemia).
  • In a study of 5,225 participants, those with lower CVH scores were at a higher risk for subclinical atherosclerosis, a condition that can lead to heart problems.
  • Improvements in CVH over time were linked to lower risks of subclinical atherosclerosis, suggesting that enhancing heart health metrics can mitigate risks associated with hyperglycemia.

  • Fish oil, rich in omega-3 fatty acids DHA and EPA, was tested for its impact on triglyceride levels and gut microbiota in patients with type 2 diabetes and high triglycerides through a 12-week study involving 309 participants.
  • The results showed that fish oil significantly reduced triglycerides more than corn oil and altered the serum lipid profile, with specific lipid metabolites mediating the relationship between gut microbiota and triglyceride reduction.
  • The study highlights the importance of individual gut microbiota characteristics in determining how effective fish oil is in lowering triglycerides, emphasizing personalized approaches for diabetes treatment.

Background: Incorporating scientific research into undergraduate medical education is necessary for the quality of future health care. However, providing rigorous research training to a large number of medical students at one institution remains one of the major challenges. The authors studied the impact of a curriculum-based Research Training Program (RTP) for all undergraduate students at Zhejiang University School of Medicine (ZUSM) on research productivity and future research interests.

Powdery mildew is a serious fungal disease in protected melon cultivation that affects the growth, development and production of melon plants. Previous studies have shown that red light can improve oriental melon seedlings resistance to powdery mildew. Here, after inoculation with Podosphaera xanthii, an obligate fungal pathogen eliciting powdery mildew, we found that red light pretreatment increased ethylene production and this improved the resistance of melon seedlings to powdery mildew, and the ethylene biosynthesis gene CmACS10 played an important role in this process.

Soil-engaging components play a critical role in agricultural production and engineering construction. However, the soil-engaging components directly interacting with the soil often suffer from the problems of high resistance, adhesion, and wear, which significantly reduce the efficiency and quality of soil operations. A large number of featured studies on the design of soil-engaging components have been carried out while applying the principles of bionics extensively, and significant research results have been achieved.

  • - The study investigates the association between the triglyceride glucose (TyG) index and breast cancer risk in Chinese women, using data from a large sample of 142,184 participants aged 40 or older.
  • - Results indicate that women in the highest quartile of the TyG index have a 61% increased risk of prevalent breast cancer compared to those in the lowest quartile, with certain demographics showing even stronger associations.
  • - The findings suggest that the TyG index may be a useful marker for assessing breast cancer risk, especially among women without insulin resistance or metabolic issues.

Soil adhesion is one of the important factors affecting the working stability and quality of agricultural machinery. The application of bionic non-smooth surfaces provides a novel idea for soil anti-adhesion. The parameters of sandy loam with 21% moisture content were calibrated by the Engineering Discrete Element Method (EDEM).

Diabetes is associated with increased oxidative stress, leading to altered tight junction formation and increased apoptosis in colonic epithelial cells. These changes may lead to intestinal barrier dysfunction and corresponding gastrointestinal symptoms in patients with diabetes, including diarrhea. The aim of this study was to characterize the effect and mechanism of Resolvin D1 (RvD1) on diabetes-induced oxidative stress and barrier disruption in the colon.

Background: The swift transition to online teaching in medical education has presented the challenge of replicating in-class engagement and interaction essential for active learning. Despite online team-based learning (TBL) offering potential solutions through structured cooperative activities, its efficacy in virtual simulation experiment courses remains scantily researched. This study investigates the effectiveness of online TBL for teaching virtual patient experiments in a basic medical laboratory course and contrasts it with traditional offline teaching in terms of student performance and perceptions.

Epidemiological studies suggested an association between omega-3 fatty acids and cognitive function. However, the causal role of the fatty acid desaturase (FADS) gene, which play a key role in regulating omega-3 fatty acids biosynthesis, on cognitive function is unclear. Hence, we used two-sample Mendelian randomization (MR) to estimate the gene-specific causal effect of omega-3 fatty acids (N = 114,999) on cognitive function (N = 300,486).

BiFeO/LaSrMnO (BFO/LSMO) epitaxial heterostructures were successfully synthesized by pulsed laser deposition on (001)-oriented SrTiO single-crystal substrates with Au top electrodes. Stable bipolar resistive switching characteristics regulated by ferroelectric polarization reversal was observed in the Au/BFO/LSMO heterostructures. The conduction mechanism was revealed to follow the Schottky emission model, and the Schottky barriers in high-resistance and low-resistance states were estimated based on temperature-dependent current-voltage curves.

Under the conditions of conservation tillage, the existence of the root-soil complex greatly increases the resistance and energy consumption of stubble-cutting blades, especially in Northeast China. In this research, the corn root-soil complex in Northeast China was selected as the research object. Based on the multi-toothed structure of the leaf-cutting ant's mandibles and the unique bite mode of its mandibles on leaves, a gear-tooth, double-disk, bionic stubble-cutting device (BSCD) was developed by using a combination of power cutting and passive cutting.

Epidemiological evidence regarding the effect of omega-3 polyunsaturated fatty acid (PUFA) supplementation on inflammatory bowel disease (IBD) is conflicting. Additionally, little evidence exists regarding the effects of specific omega-3 components on IBD risk. We applied two-sample Mendelian randomization (MR) to disentangle the effects of omega-3 PUFAs (including total omega-3, α-linolenic acid, eicosapentaenoic acid (EPA), or docosahexaenoic acid (DHA)) on the risk of IBD, Crohn's disease (CD) and ulcerative colitis (UC).

Ribonucleotide reductase (RR) is a rate-limiting enzyme that facilitates DNA replication and repair by reducing nucleotide diphosphates (NDPs) to deoxyribonucleotide diphosphates (dNDPs) and is thereby crucial for cell proliferation and cancer development. The E2F family of transcription factors includes key regulators of gene expression involved in cell cycle control. In this study, E2F8 expression was significantly increased in most cancer tissues of lung adenocarcinoma (LUAD) patients and was correlated with the expression of RRM2 through database and clinical samples analysis.
