Background: Bacterial wilt (BW), caused by Ralstonia solanacearum (Rs), is one of the most destructive diseases impacting a wide range of crops globally. The infection process is complex involving intricate interactions between the plant and Rs. Managing BW is challenging, and crop breeding remains the most effective strategy for disease control.

Background: The prognosis for patients with esophageal cancer who received neoadjuvant chemoradiotherapy (nCRT) followed by surgery has shown improvement in recent years. We sought to identify the critical factors contributing to enhanced survival outcomes.

Patients And Methods: We retrospectively examined 427 patients with esophageal cancer treated with nCRT and esophagectomy across two periods: P1 (from 1 January 2004 to 31 December 2011) and P2 (from 1 January 2012 to 31 December 2017).

IMP-3 expression is a poor prognostic factor of melanomas and it promotes melanoma cell migration and invasion by a pathway modulating HMGA2 mRNA expression. We tried to identify other putative targets of IMP-3. We identified putative IMP-3-binding RNAs, including AKT1, MAPK3, RB1 and RELA, by RNA immunoprecipitation coupled with next-generation sequencing.

Objectives: Respiratory syncytial virus (RSV) causes clinically significant distress in children and adults. Non-pharmaceutical interventions against SARS-CoV-2 have affected the seasonal activity of common respiratory pathogens. This seems exceptionally true regarding RSV's seasonal circulation, hence we have investigated the changes in the epidemiology of RSV in Taiwan during the pandemic.

Article Synopsis
  • Ankylosing spondylitis (AS) is an autoimmune disease primarily affecting the spine and sacroiliac joints, and this study focused on discovering race-specific genetic factors for AS in Taiwanese individuals through genome-wide association studies (GWAS).
  • The researchers conducted a case-control study utilizing genotyping data from a Taiwanese medical center and identified single nucleotide polymorphisms (SNPs) that increased AS susceptibility, particularly those located on the sixth chromosome.
  • Findings revealed that these SNPs were unique to the Taiwanese population, with a notable correlation between HLA-B27 positivity and AS risk, leading to the development of polygenic risk score models that indicated those in the top 10% had a significantly higher risk of developing AS

Background: Cluster headache is a highly debilitating neurological disorder with considerable inter-ethnic differences. Genome-wide association studies (GWAS) recently identified replicable genomic loci for cluster headache in Europeans, but the genetic underpinnings for cluster headache in Asians remain unclear. The objective of this study is to investigate the genetic architecture and susceptibility loci of cluster headache in Han Chinese resided in Taiwan.

Background: Liquid nitrogen (LN) has been used as an adjuvant cryotherapy for bone tumors including giant-cell tumor of the bone (GCTB) to remove residual tumor cells after curettage. This study evaluated variables related to the efficacy of LN-based cryoablation in the context of adjuvant treatment of GCTB using porcine femur bone model.

Methods: A porcine femur bone model was adopted to simulate intralesional cryotherapy.

Background: Restoration of height or angle has been reported following vertebroplasty (VP). The purpose of the study was to investigate the predictive value of the preoperative lateral fulcrum radiograph (LFR) of success in one-level VP for painful osteoporotic vertebral fracture.

Methods: From January 2017 to January 2018, 71 patients (mean age, 76 years) receiving VP were retrospectively analyzed.

Article Synopsis
  • The study aimed to analyze the epidemiology and diagnoses related to Meckel's diverticulum (MD) using Taiwan's National Health Insurance Research Database, focusing on patients who had intestinal surgery.
  • Researchers identified 2,453 newly diagnosed MD patients from 1996 to 2013, with 50% being symptomatic, often presenting issues like intestinal obstruction, acute appendicitis, and gastrointestinal bleeding.
  • Findings showed that the male-to-female ratio was 2.4:1, and half of the symptomatic patients were under 20 years old, providing insights into MD symptom distribution across different age groups for better clinical understanding.

Background: Human respiratory syncytial virus (RSV) is a leading pathogen of acute respiratory tract disease among infants and young children. Compared with previous seasons, RSV outbreaks in Taiwan during the 2020-2021 season were delayed because of COVID-19 mitigation measures. We conducted this study to determine the association of viral factors with clinical characteristics of preschool children with RSV infection.

Aims: The risk of antipsychotic-associated cardiovascular and metabolic events may differ among countries, and limited real-world evidence has been available comparing the corresponding risks among children and young adults. We, therefore, evaluated the risks of cardiovascular and metabolic events in children and young adults receiving antipsychotics.

Methods: We conducted a multinational self-controlled case series (SCCS) study and included patients aged 6-30 years old who had both exposure to antipsychotics and study outcomes from four nationwide databases of Taiwan (2004-2012), Korea (2010-2016), Hong Kong (2001-2014) and the UK (1997-2016) that covers a total of approximately 100 million individuals.

A wealth of evidence has shown that a single bout of aerobic exercise can facilitate executive function. However, none of current studies on this topic have addressed whether the magnitude of the acute-exercise benefit on executive function and oculomotor performance is influenced by different aerobic exercise modes. The present study was thus aimed toward an investigation of the acute effects of high-intensity interval exercise (HIIE) vs.

  • - The study investigates the heritability of how well individuals with type 2 diabetes respond to sulfonylureas, a common class of medication, and identifies genetic factors influencing glycemic response (HbA reduction).
  • - Researchers analyzed data from 5,485 White Europeans and found significant heritability (37%) and identified two genetic loci linked to reduced HbA levels.
  • - Specific genetic variants were shown to correlate with differing responses to sulfonylureas, highlighting the importance of genetic factors in diabetes treatment effectiveness.

The purposes of the present study were (1) to explore and compare the acute effects of high-intensity interval training (HIIT) and moderate-intensity continuous exercise (MICE) on neurocognitive performance and molecular biomarkers in late middle-aged and older adults, and (2) to examine the relationships of HIIT/MICE exercise-induced neurocognitive changes with changes in circulating irisin and BDNF levels elicited by different acute exercise modes. Using a within-subject design, twenty-one participants completed an acute bout of 30 min of HIIT, MICE, or a non-exercise-intervention (REST) session in a counterbalanced order. The neuropsychological [i.

Background: This study was conducted to identify risk factors for distant interval metastases (IM) in patients with esophageal squamous cell carcinoma (ESCC) who underwent chemoradiotherapy (CRT).

Methods: We retrospectively reviewed the clinical records of 358 patients with ESCC treated with CRT between 2006 and 2017. Distant IM were defined as systemic metastases developing during or shortly after CRT and identified during the restaging work-up period.

Pyrrhotite nanoparticles with 5C and 3C superstructures were synthesized via a simple one-step thermal decomposition method in which hexadecylamine was used as a solvent at various reaction temperatures (T). Structural analysis showed that at T = 360 °C, almost uniform in size and shape FeS nanoparticles with 3C superstructure are formed, and an increase in the reaction temperature leads to the formation of FeS nanoparticles (5C superstructure), herewith a significant increase in the size of nanoparticles is observed. High-temperature magnetic measurements in 5 repeated heating-cooling cycles revealed that after the first heating branch in the FeS samples, the λ-Peak transition disappears, and the magnetization has a Weiss-type behavior characteristic of the FeS sample.

The current state of the COVID-19 pandemic is a global health crisis. To fight the novel coronavirus, one of the best-known ways is to block enzymes essential for virus replication. Currently, we know that the SARS-CoV-2 virus encodes about 29 proteins such as spike protein, 3C-like protease (3CLpro), RNA-dependent RNA polymerase (RdRp), Papain-like protease (PLpro), and nucleocapsid (N) protein.
