Biological Control of Avocado Branch Blight Caused by Lasiodiplodia theobromae Using Bacillus velezensis.

In recent years, avocado branch blight has gradually become one of the major diseases causing mortality of avocado trees, which seriously affects the economic development of avocado planting regions. In order to investigate the cause of the disease, the pathogens were isolated from the interroot of avocado trees with the onset of the disease and identified as Lasiodiplodia theobromae. At the same time, three Bacillus velezensis strains, YK194, YK201, and YK268, with better antagonistic effects and high stability against L. theobromae, were isolated from the rhizospheric soil of healthy avocado plants. The results of branch experiments and field trials showed that the avocado leaves as well as branches treated with the strains YK194, YK201, and YK268 did not develop disease, and the incidence of avocado trees was significantly reduced. In the branch experiments, the biological control effect of the strains YK194, YK201, and YK268 reached 62.07, 52.70, and 72.45%, respectively. In the field experiments, it reached 63.85, 63.43, and 73.86%, respectively, which indicated that all these three strains possessed good biological control effects on avocado branch blight. Further investigation on the mechanism of action of antagonistic strains revealed that B. velezensis YK268 could produce lipopeptides, namely, surfactin, fengycin, and iturin, which could significantly inhibit the spore germination of L. theobromae. Consequently, these three isolates have potential as biocontrol agents against L. theobromae.

Base editing strategies to convert CAG to CAA diminish the disease-causing mutation in Huntington's disease.

An expanded CAG repeat in the huntingtin gene (HTT) causes Huntington's disease (HD). Since the length of uninterrupted CAG repeat, not polyglutamine, determines the age-at-onset in HD, base editing strategies to convert CAG to CAA are anticipated to delay onset by shortening the uninterrupted CAG repeat. Here, we developed base editing strategies to convert CAG in the repeat to CAA and determined their molecular outcomes and effects on relevant disease phenotypes. Base editing strategies employing combinations of cytosine base editors and guide RNAs (gRNAs) efficiently converted CAG to CAA at various sites in the CAG repeat without generating significant indels, off-target edits, or transcriptome alterations, demonstrating their feasibility and specificity. Candidate BE strategies converted CAG to CAA on both expanded and non-expanded CAG repeats without altering HTT mRNA and protein levels. In addition, somatic CAG repeat expansion, which is the major disease driver in HD, was significantly decreased in the liver by a candidate BE strategy treatment in HD knock-in mice carrying canonical CAG repeats. Notably, CAG repeat expansion was abolished entirely in HD knock-in mice carrying CAA-interrupted repeats, supporting the therapeutic potential of CAG-to-CAA conversion strategies in HD and potentially other repeat expansion disorders.

Investigating the Precise Identification of Citrullination Sites with High-Performance Score Metrics using a Powerful Computation Predicting Tool.

To elucidate the detailed mechanisms of citrullination at the molecular level and design drugs applicable to major human diseases, predicting protein citrullination sites (PCSs) is essential. Using experimental approaches to predict PCSs is time-consuming and costly. However, there is a limited scope of the current PCS predictors. In particular, most predictors are commonly used for PCS prediction and have limited performance scores. This work aims to provide an improved sophisticated predictor of citrullination sites using a benchmark dataset in a machine learning platform. This study presents a reliable citrullination site predictor based on a benchmark dataset containing a 1:1 ratio of positive and negative samples. We classified citrullination sites using the Composition of the K-Spaced Amino Acid Pairs (CKSAAP) and Support Vector Machine (SVM). We developed PCS predictors using integrated machine-learning methods that produced the highest average scores. Using 10-fold cross-validation on test datasets, the True Positive Rate (TPR) was 98.34%, the True Negative Rate (TNR) was 99.44%, the accuracy was 98.89%, the Mathew Correlation Coefficient (MCC) was 98.21%, the Area Under the ROC Curve (AUC) was 0.999, and the partial Area Under the ROC Curve (pAUC) was 0.1968. According to overall performance, our developed predictor has a significantly higher implementation in comparison with the current tools on the same benchmark dataset. Moreover, it showed better performance metrics on both test and training datasets. Our developed predictor is promising and can be implemented as a complementary technique for identifying fast and precise citrullination sites.

Main causes of death in Italy

Understanding the major diseases processes which lead to mortality is an important aspect of healthcare planning, especially with regards to the life periods in which death is considered as “avoidable” i.e. premature (generally before the age of 70). From a methodological point of view, the identification of the major causes of death is based on the criterion of frequency. We consider the weight of deaths due to a specific cause in relation to all deaths and then define the main causes of death in relation to the highest weights. The selection criterion is thus merely quantitative.

Early enteral nutrition support for patients with acute pancreatitis in the inpatient setting: a best practice implementation project.

Acute pancreatitis is a major disease that endangers the health and lives of people. Historically, clinical therapy has recommended. that patients with acute pancreatitis remain nil by mouth. As one of the therapies recommended in recent guidelines, early enteral nutrition support reduces the incidence of infectious complications and reduces the risk of severe conditions. However, early enteral nutrition support has not been optimally implemented within clinical practice for acute pancreatitis inpatients. This evidence implementation project aimed to increase compliance with best practice recommendations for early enteral nutrition support, while standardizing the enteral nutrition support process and reducing the incidence of delayed enteral nutrition. The project was guided by the JBI Evidence Implementation Framework, which is grounded in the audit and feedback process, as well as a seven-stage structured approach to identifying and managing barriers to compliance with recommended practices. In the baseline audit, compliance rates were low for all evidence-based audit criteria. Four of the eight criteria showed 0% compliance. However, after implementation, all eight criteria achieved a minimum compliance rate of 60%, with Site 2 achieving 90% to 100% compliance. In addition, nurses improved their knowledge and skills in early enteral nutrition support. The incidence of delayed enteral nutrition also fell from 86.2% to 20.7% at both study sites. The implementation strategy included a training program, psychological interventions, and financial and human resource support. This project not only significantly improved early enteral nutrition support for acute pancreatitis patients, but also increased nurses' knowledge and practice skills, standardized the process of enteral nutrition support, and reduced the incidence of delayed enteral nutrition. http://links.lww.com/IJEBH/A177.

Biochemical Changes: Their Potential Role against Fungal Disease Resistance Development in Mustard

Rape-seed mustard is an imperative edible oilseed crop which is adversely affected by different biotic stresses causing import of edible oils from abroad. The experiment was carried out for screening mustard genotypes based on disease indexing and putative role of diverse biochemical parameters in development of resistant against three major fungal diseases. A modified 0-9 scale was used for rating of disease indicators to calculate disease incident (DI). In disease indexing, mustard genotypes L-4, GSC-7 and PC-6 were considered as immune against Alternaria brassicae, Maya, L-4, China, GSL-1, GSC-7, PC-5, PC-6 and RP-9 were classified as immune against Albugo candida while L-4 and PC-5 were found immune against Erysiphe cruciferarum. The study of biochemical constituents demonstrated that these immune genotypes accumulated higher osmolytes content including free proline content and total phenol under diseased condition showing their tolerance ability against these pathogens. The tolerant genotypes also had lesser lipid peroxidation rate as indicated by malondialdehyde content analysis to induce lesser effect on total chlorophyll, amino acids, proteins and soluble sugars including reducing and non-reducing sugars. These identified genotypes have wider scope for further phyto-pathological studies and utilization in development of fungal resistance breeding.

Impact of biotic stresses on the Brassicaceae family and opportunities for crop improvement by exploiting genotyping traits.

Utilizing RNAi, miRNA, siRNA, lncRNA and exploiting genotyping traits can help safeguard the food supply from illnesses and pest damage to Brassicas, as well as reduce yield losses caused by plant pathogens and insect pests. In the natural environment, plants face significant challenges in the form of biotic stress, due to various living organisms, leading to biological stress and a sharp decline in crop yields. To cope with these effects, plants have evolved specialized mechanisms to mitigate these challenges. Plant stress tolerance and resistance are influenced by genes associated with stress-responsive pathogens that interact with various stress-related signaling pathway components. Plants employ diverse strategies and mechanisms to combat biological stress, involving a complex network of transcription factors that interact with specific cis-elements to regulate gene expression. Understanding both plant developmental and pathogenic disease resistance mechanisms can allow us to develop stress-tolerant and -resistant crops. Brassica genus includes commercially important crops, e.g., broccoli, cabbage, cauliflower, kale, and rapeseed, cultivated worldwide, with several applications, e.g., oil production, consumption, condiments, fodder, as well as medicinal ones. Indeed, in 2020, global production of vegetable Brassica reached 96.4 million tones, a 10.6% rise from the previous decade. Taking into account their commercial importance, coupled to the impact that pathogens can have in Brassica productivity, yield losses up to 60%, this work complies the major diseases caused due to fungal, bacterial, viral, and insects in Brassica species. The review is structured into three parts. In the first part, an overview is provided of the various pathogens affecting Brassica species, including fungi, bacteria, viruses, and insects. The second part delves into the exploration of defense mechanisms that Brassica plants encounter against these pathogens including secondary metabolites, duplicated genes, RNA interference (RNAi), miRNA (micro-RNA), siRNA (small interfering RNA), and lncRNA (long non-coding RNA). The final part comprehensively outlines the current applications of CRISPR/Cas9 technology aimed at enhancing crop quality. Taken collectively, this review will contribute to our enhanced understanding of these mechanisms and their role in the development of resistance in Brassica plants, thus supporting strategies to protect this crucial crop.

Research Progress and Clinical Value of Subendocardial Viability Ratio.

Cardiovascular disease remains the leading cause of morbidity and mortality worldwide, with ischemic heart disease being a major contributor, either through coronary atherosclerotic plaque-related major vascular disease or coronary microvascular dysfunction. Obstruction of coronary blood flow impairs myocardial perfusion, which may lead to acute myocardial infarction in severe cases. The subendocardial viability ratio, also known as the Buckberg index, is a valuable tool for evaluation of myocardial perfusion because it reflects the balance between myocardial oxygen supply and oxygen demand. The subendocardial viability ratio can effectively evaluate the function of the coronary microcirculation and is associated with arterial stiffness. This ratio also has potential value in predicting adverse cardiovascular events and mortality in various populations. Moreover, the subendocardial viability ratio has demonstrated clinical significance in a range of diseases, including hypertension, aortic stenosis, peripheral arterial disease, chronic kidney disease, diabetes, and rheumatoid arthritis. This review summarizes the applications of the subendocardial viability ratio, its particular progress in the relevant research, and its clinical significance in cardiovascular diseases.

Comparative transcriptomic analysis reveals differences in gene expression and regulatory pathways between nonacral and acral melanoma in Asian individuals.

Melanoma predominantly occurs in White individuals, which is associated with factors such as exposure to UV radiation and skin pigmentation. Despite its low incidence, melanoma is the primary cause of skin cancer-related death in Asia, typically in areas with low sun exposure. In our previous whole-exome sequencing study, we identified mutational signature 12 as the most prevalent variant in Asian patients, differing from the common UV-associated mutational signature 7 observed in White individuals. We also observed major differences between acral melanoma (AM) and nonacral melanoma (NAM) in terms of signatures 7, 21, and 22. Notably, few studies have investigated the genomic differences between AM and NAM in Asian individuals. Therefore, in this study, we conducted transcriptomic sequencing to examine the disparities in RNA expression between AM and NAM. Ribosomal RNA depletion was performed to enhance the detection of functionally relevant coding and noncoding transcripts. Ingenuity pathway analysis revealed significant differences in gene expression and regulatory pathways between AM and NAM. The results also indicate that the genes involved in cell cycle signaling or immune modulation and programmed cell death protein 1/programmed cell death 1 ligand 1 signaling were differentially expressed in NAM and AM. In addition, high CDK4 expression and cell cycle variability were observed in AM, with high immunogenicity in NAM. Overall, these findings provide further insights into the pathogenesis of melanoma and serve as a reference for future research on this major malignant disease.

Citrus Black Spot Disease in Ghana: A Review on Impacts, Management Options and Current Status

Citrus is one of the most common seasonal fruit crops cultivated across most semi-deciduous forest zones across the globe. Apart from its refreshing nature when consumed in a fresh state, it is also packed with an abundant supply of vitamins A, B and C. Apart from being served in the raw state as a fruit or a dessert, it also serves as a critical raw material for the beverage industry. In some instances, it also serves as a very important material for the pharmaceutical industry. As important as this fruit can be, its production is challenged by the incidence of pests and diseases. One of the major diseases facing the industry is the Citrus Black Spot (CBS), caused by Phyllosticta citricarpa. In Ghana, CBS is known to affect almost all citrus species and varieties in commercial groves, except for sour orange (C. aurantium) and its hybrids and Tahiti lime (C. latifolia). It is estimated to be responsible for about 22% of fruit/yield loss annually. This review highlighted the impact on the citrus production industry in Ghana, the management options available and future perspectives.

 Conclusion: This study shows that considerable numbers of both pathogenic bacteria and fungi particles were released into the air in higher quantity after flushing domestic toilets when compared to air quality before flushing. These organisms have been implicated in major and minor infectious diseases. Inhalation or contact may easily lead to infection especially in immunocompromised individuals and the older adults. To maintain the health of users, it is necessary to carefully manage the environmental factors that promote the growth and multiplication of microorganisms in domestic toilet environment.

Theranostic Agent Targeting Bone Metastasis: A Novel [68Ga]Ga/[177Lu]Lu-DOTA-HBED-bisphosphonate.

Bone metastasis in cancer patients is a major disease advancement for various types of cancer. Previously, [68Ga]Ga-HBED-CC-bisphosphonate ([68Ga]Ga-P15-041) showed excellent bone uptake and efficient detection of bone metastasis in patients. To accommodate different α- or β--emitting metals for radionuclide therapy, a novel DOTA-HBED-CC-bisphosphonate (P15-073, 1) was prepared and the corresponding [68Ga]Ga-1 and [177Lu]Lu-1 were successfully synthesized in high yields and purity. Gallium-68 conjugation to HBED-CC at room temperature and lutetium-177 conjugation to DOTA at 95 °C were verified in model compounds through secondary mass confirmation. These bisphosphonates, [68Ga]Ga-1 and [177Lu]Lu-1, displayed high binding affinity to hydroxyapatite in vitro. After an iv injection, it showed excellent uptake in the spine of normal mice, and micro-PET/CT imaging of nude mice model of bone metastasis showed high bone uptake in tumor tissue. The results indicated that [68Ga]Ga/[177Lu]Lu-1 holds promise as a theranostic radioligand agent for managing cancer bone metastases.

Causal role of immune cells in obstructive sleep apnea hypopnea syndrome: Mendelian randomization study

BACKGROUND Despite being one of the most prevalent sleep disorders, obstructive sleep apnea hypoventilation syndrome (OSAHS) has limited information on its immunologic foundation. The immunological underpinnings of certain major psychiatric diseases have been uncovered in recent years thanks to the extensive use of genome-wide association studies (GWAS) and genotyping techniques using high-density genetic markers (e.g. , SNP or CNVs). But this tactic hasn't yet been applied to OSAHS. Using a Mendelian randomization analysis, we analyzed the causal link between immune cells and the illness in order to comprehend the immunological bases of OSAHS. AIM To investigate the immune cells' association with OSAHS via genetic methods, guiding future clinical research. METHODS A comprehensive two-sample mendelian randomization study was conducted to investigate the causal relationship between immune cell characteristics and OSAHS. Summary statistics for each immune cell feature were obtained from the GWAS catalog. Information on 731 immune cell properties, such as morphologic parameters, median fluorescence intensity, absolute cellular, and relative cellular, was compiled using publicly available genetic databases. The results' robustness, heterogeneity, and horizontal pleiotropy were confirmed using extensive sensitivity examination. RESULTS Following false discovery rate (FDR) correction, no statistically significant effect of OSAHS on immunophenotypes was observed. However, two lymphocyte subsets were found to have a significant association with the risk of OSAHS: Basophil %CD33dim HLA DR- CD66b- (OR = 1.03, 95%CI = 1.01-1.03, P < 0.001); CD38 on IgD+ CD24- B cell (OR = 1.04, 95%CI = 1.02-1.04, P = 0.019). CONCLUSION This study shows a strong link between immune cells and OSAHS through a gene approach, thus offering direction for potential future medical research.

The Up-Regulated Expression of Mitochondrial Membrane Molecule RHOT1 in Gastric Cancer Predicts the Prognosis of Patients and Promotes the Malignant Biological Behavior of Cells.

Gastric cancer (GC) remains a major disease of high morbidity and mortality worldwide despite advances in diagnosis and treatment. Ras homolog family member T1 (RHOT1) plays an important role in several cancers. Our study aimed to analyze RHOT1 expression, to assess the relationship between its expression and the prognosis of patients, and know the impact of RHOT1 on GC cells. The Cancer Genome Atlas (TCGA) RNA-seq data was used for gene expression analysis, survival and prognostic analysis. Nomograms were created to analyze the pathological factors of GC patients. RHOT1 expression was up-regulated by analyzed TCGA-Stomach adenocarcinoma (STAD) data and verified by Polymerase Chain Reaction (PCR) assay in GC tissues and cell lines. Furthermore, RHOT1 up-regulation was significantly associated with shorter survival of GC patients. At last, after silencing the expression of RHOT1 in AGS cell lines, we found that the proliferative ability of the cells was significantly reduced, the cell invasion ability was significantly inhibited, the cell migration ability was also significantly weakened, the cell cycle was arrested in the G0/G1 phase, and apoptosis was significantly increased. So RHOT1 could impact the apoptosis, proliferation, invasion, and migration behavior of GC cells. We trust RHOT1 has the potential to become a new oncogene biomarker for diagnosis and prognosis as well as a new therapeutic target in GC.
