Fever has long been recognized as one of the earliest clinical indicators of illness and remains a leading reason for seeking medical care worldwide. It is typically classified based on its duration and underlying etiology. In clinical settings, intractable fever is as common as acute fever, particularly in patients with brain injuries.

Previous studies have demonstrated that genetic alterations governing epigenetic processes frequently drive tumor development and that modifications in RNA may contribute to these alterations. In the 1970s, researchers discovered that N6-methyladenosine (mA) is the most prevalent form of RNA modification in advanced eukaryotic messenger RNA (mRNA) and noncoding RNA (ncRNA). This modification is involved in nearly all stages of the RNA life cycle.

Article Synopsis
  • Adventitious roots (ARs) are crucial for lotus plants' water and nutrient absorption, especially after the main root degenerates, and the WOX gene family plays a significant role in plant development.
  • Three specific WOX genes (NnWOX1-1, NnWOX4-3, and NnWOX5-1) were studied in Arabidopsis, showing their sizes and confirming their relationships with other genes, alongside organ-specific responses to sucrose and IAA.
  • NnWOX1-1 and NnWOX4-3 were found to enhance root growth, salt tolerance, and stem development, with the influence on gene expression linked to ethylene metabolism being particularly impactful for

Objective: To examine the efficacy of early intervention (4 weeks before pollen dispersal) with sphenopalatine ganglion (Xinwu acupoint) stimulation in patients with allergies after the onset of seasonal allergic rhinitis (SAR).

Methods: This is a prospective, randomized and unblinded half-open study. Forty-one SAR volunteers were randomly assigned to either the sphenopalatine ganglion (SPG) acupuncture plus supplementary acupuncture (SPG group) or the sham-SPG acupuncture plus supplementary acupuncture (SA group) stimulation 4 weeks before the onset of allergy season.

The component of human life that has been most significantly altered by the COVID-19 epidemic is travel. Due to the upheaval produced by the pandemic breakout, countries are becoming increasingly avaricious and are scrambling to stockpile vaccines. The world has been locked down to reduce/control the pandemic outbreak, driving countries to shut their doors to other people from countries.

Article Synopsis
  • The study aimed to identify the causes of a diarrhea outbreak in a particular town and suggest ways to prevent future occurrences.
  • A total of 133 cases were identified, with symptoms primarily including diarrhea, fever, and abdominal pain, and the majority of those affected had consumed non-boiled water prior to the outbreak.
  • The results indicated that contaminated drinking water was the main source of the outbreak, highlighting the need for improved sanitation of water supplies and changes in drinking habits to prevent similar incidents.

Background: COVID-19 is a new coronavirus that constitutes a great challenge to human health. At this stage, there are still cases of COVID-19 infection in some countries and regions, in which ischemic stroke (IS) is a risk factor for new coronavirus pneumonia, and patients with COVID-19 infection have a dramatically elevated risk of stroke. At the same time, patients with long-term IS are vulnerable to COVID-19 infection and have more severe disease, and carotid atherosclerosis is an early lesion in IS.

Tubulin vinca-domain ligands can inhibit microtubule polymerization, causing cell death in mitosis, and their potential against multiple cancer types has been demonstrated. However, due to drug resistance and toxicities, development of novel vinca-domain ligands is still needed. In this study, we determined the high-resolution crystal structures of vinorelbine, YXD, and Phomopsin A in complex with tubulin at 2.

Background: Lotus is an aquatic horticultural crop that is widely cultivated in most regions of China and is used as an important off-season vegetable. The principal root of lotus is degenerated, and adventitious roots (ARs) are irreplaceable for plant growth. We found that no ARs formed under darkness and that exposure to high-intensity light significantly promoted the development of root primordia.

Introduction: We aimed to analyze the psychological status in patients with breast cancer (BC) in the epicenter of the coronavirus disease 2019 (COVID-19) pandemic.

Patients And Methods: A total of 658 individuals were recruited from multiple BC centers in Hubei Province. Online questionnaires were conducted, and these included demographic information, clinical features, and 4 patient-reported outcome scales (Generalized Anxiety Disorder Questionnaire [GAD-7], Patient Health Questionnaire [PHQ-9], Insomnia Severity Index [ISI], and Impact of Events Scale-Revised [IES-R]).

MicroRNA (miRNA)-regulated gene expression plays an important role in various plant metabolic processes. Although adventitious roots are critical to plant growth in lotus, the role of miRNA in AR formation remains unclear. Expression profiling of miRNAs was carried out during three different developmental stages of ARs in lotus: no induction of AR stage, initial stage of ARs, and maximum number of ARs.

Pregnant women living with HIV represent one of the most high-priority groups for HIV treatment and health assessment. Although social support has been shown to be a protective factor for improved health-related quality of life (HRQoL), and depression and anxiety have been identified as two major causes of psychological distress among people living with HIV, it is still unclear how social support, anxiety, and depression interact to influence HRQoL. The objective of our study was to demonstrate the nature of predictors, direct effects and mediator effects among social support, anxiety, depression symptoms and HRQoL in pregnant women living with HIV.

The relationship between hepatitis B virus (HBV) and the prognosis of hepatocellular carcinoma (HCC) after surgery remains uncertain. A retrospective cohort study was performed to evaluate the impact of pre-S deletions, T1762/A1764, and A1896 mutations on prognosis of HCC after curative resection. A total of 113 patients with positive serum HBV DNA (>200 IU/mL) who had underwent curative resection of pathologically proven HCC were recruited to determine the risk factors affecting the prognosis.

Objectives: Although family planning in China has changed gradually since 1994, there are few studies about family planning and women's reproductive rights. The main objective of this study was to examine awareness of sexual and reproductive healthcare rights (SRHCRs), and learn how factors related to family planning influence awareness of SRHCRs among married women of reproductive age in China.

Methods And Participants: Inner Mongolia, Chongqing, Guangdong and Henan were selected for the study, and a total of 2504 married women of reproductive age were recruited.

To identify the genomic profile and elucidate the pathogenesis of hepatoblastoma (HBL), the most common pediatric hepatic tumor, we performed high-density genome-wide single-nucleotide polymorphism (SNP) microarray analyses of 17 HBL samples. The copy number analyzer for GeneChip(R) (CNAG) and allele-specific copy number analysis using anonymous references (AsCNAR) algorithms enabled simple but sensitive inference of allelic composition without using paired normal DNA. Chromosomal aberrations were observed in 15 cases (88%).

Low serum zinc levels are harmful to semen quality in Chinese men. In this study, eligible men aged 20-59 years old-excluding those who had ever had urinary or genital disease, tuberculosis, or occupational heavy metal contact-were examined for semen quality and serum zinc and copper concentrations. Progressive motility showed differences among the five copper groups, but multiple logistic analyses did not show that higher or lower serum copper levels had a significant effect on sperm quality.
