Idiopathic pulmonary fibrosis is known as a life-threatening disease with high mortality and limited therapeutic strategies. In addition, the molecular mechanism by which pulmonary fibrosis developed is not fully understood. Asiatic acid (AA) is a triterpenoid, isolated from Centella asiatica, exhibiting efficient anti-inflammatory and anti-oxidative activities. In our study, we attempted to explore the effect of Asiatic acid on bleomycin (BLM)-induced pulmonary fibrosis in mice. The findings indicated that pre-treatment with Asiatic acid inhibited BLM-induced lung injury and fibrosis progression in mice...

BACKGROUND: Enteroinvasive Escherichia coli (EIEC) may be the causative agent of part of those million cases of diarrhea illness reported worldwide every year and attributable to Shigella. That is because both enteropathogens have many common characteristics that difficult their identification either by traditional microbiological methods or by molecular tools used in the clinical laboratory settings. While Shigella has been extensively studied, EIEC remains barely characterized at the molecular level...

Prostate cancer (PCa) is the most common type of cancer and the second leading cause of cancer-related death in men. Despite extensive research, the molecular mechanisms underlying PCa initiation and progression remain unclear, and there is increasing need of better biomarkers that can distinguish indolent from aggressive and life-threatening disease. With the advent of advanced genomic technologies in the last decade, it became apparent that the human genome encodes tens of thousands non-protein-coding RNAs (ncRNAs) with yet to be discovered function...

Life as we know it, simply would not exist without DNA replication. All living organisms utilize a complex machinery to duplicate their genomes and the central role in this machinery belongs to replicative DNA polymerases, enzymes that are specifically designed to copy DNA. "Hassle-free" DNA duplication exists only in an ideal world, while in real life, it is constantly threatened by a myriad of diverse challenges. Among the most pressing obstacles that replicative polymerases often cannot overcome by themselves are lesions that distort the structure of DNA...

Cardiac autonomic neuropathy (CAN) may lead to life threatening arrhythmia due to denervation of both the parasympathetic and sympathetic branches of autonomic nervous system innervating the heart. CAN is a frequently under diagnosed complication of diabetes, because a patient can have asymptomatic CAN for several years before it is clinically apparent. However, detection of CAN at the early or subclinical stage leads to more effective treatment outcomes. Cardiac autonomic reflex tests (CART) (i.e. Ewing test battery) are normally used for the detection and staging of CAN...

Vemurafenib and dabrafenib, two Food and Drug Administration-approved selective BRAF kinase inhibitors (BRAFi), have revolutionized the targeted therapy of cutaneous melanoma. Off-target effects of these drugs paradoxically activate the MAP kinase pathway in BRAF wild-type cells, leading to secondary malignancies. Although cutaneous squamous cell carcinomas are by far the most frequent, emergence of potentially life-threatening secondary tumors from other sites following prolonged therapy is a growing concern...

Kawasaki disease (KD) is a paediatric vasculitis whose pathogenesis remains unclear. Based on experimental studies using a mouse model for KD, we report here that proline-rich protein tyrosine kinase 2 (Pyk2) plays a critical role in the onset of KD-like murine vasculitis. The mouse model for KD was prepared by administrating a Candida albicans water-soluble fraction (CAWS). Unlike CAWS-treated WT mice, CAWS-treated Pyk2-Knockout (Pyk2-KO) mice did not develop apparent vasculitis. A sustained increase in MIG/CXCL9 and IP-10/CXCL10, both of which have potent angiostatic activity, was observed in CAWS-treated Pyk2-KO mice...

QUESTION: For many years, the term apparent life-threatening event (ALTE) was associated with sudden infant death syndrome, and parents who described an acute event in their infants were sent to the hospital for admission. I understand that for infants new terminology is recommended. What is the current approach to a near-death experience of an infant? ANSWER: A recent clinical practice guideline revised the name and definition of an ALTE to a brief resolved unexplained event (BRUE)...

The risk factors for recurrent apparent life-threatening event (ALTE) are unclear although the risk of recurrent ALTE is an important consideration for the management of ALTE patients. This study aimed to identify the risk factors for recurrent ALTE. We conducted a secondary analysis of the data from a single center retrospective cohort study in Japan conducted from March 2002 to January 2012, which included children diagnosed with ALTE at a pediatric emergency department (ED) in Tokyo. Among 112 ALTE patients, 18 (16%) had recurrences and 94 (84%) did not...

Bright sunlight may create visual illusions that lead to driver error, including fallible distance judgment from aerial perspective. We tested whether the risk of a life-threatening motor vehicle crash was increased when driving in bright sunlight.This longitudinal, case-only, paired-comparison analysis evaluated patients hospitalized because of a motor vehicle crash between January 1, 1995 and December 31, 2014. The relative risk of a crash associated with bright sunlight was estimated by evaluating the prevailing weather at the time and place of the crash compared with the weather at the same hour and location on control days a week earlier and a week later...

Human cytomegalovirus (HCMV) is a betaherpesvirus that can be pathogenic to humans. In particular, immunocompromised patients can develop life-threatening symptoms. In the present study, HCMV seroprevalence was investigated in a rural population of Western Côte d'Ivoire. Plasma samples collected from 166 apparently healthy subjects living in 8 villages surrounding the Taï Forest National Park were tested for anti-HCMV immunoglobulin G and M antibody with two commercial enzyme-linked immunosorbent assays. Prevalence of anti-HCMV IgG and IgM antibody was 100% and 5...

Pyomyoma is an unusual complication of leiomyoma, occurring most commonly in the postpartum, postabortal, and post-menopausal periods. It develops due to infection in necrotic foci within leiomyoma, which is more common during pregnancy due to rapid growth, and in postmenopausal women due to vascular insufficiency. Other contributing factors are curettage, gynecological surgery, cervical stenosis, immunodeficiency, and recently, uterine artery embolization. It presents with a typical triad of sepsis, leiomyoma, and absence of any apparent source of infection...

BACKGROUND: Anterior cervical discectomy (ACD) is one of the most common spinal surgeries. Although rare, iatrogenic vertebral artery injuries (VAIs) are potentially life-threatening. Risk factors are anatomic, operative, and pathologic. We report a rare case of iatrogenic VAI during ACD and successful endovascular treatment with no long-term complications. We also review the literature on all VAIs associated with ACD and fusions. Risk factors and the safety and effectiveness of various management modalities are discussed...

BACKGROUND: Transplanted heart dysfunction is a serious life-threatening condition in pediatric transplant recipients. Several studies have focused on echocardiographic detection of early signs of cardiac dysfunction in this population. We evaluated advanced echocardiographic indices of cardiac function in a large sample of children and young adults with heart transplants with apparently normal cardiac function. METHODS: The study included 60 patients with normal ejection fraction with transplantation performed at pediatric age between 1986 and 2014 and 60 healthy control subjects...

PURPOSE: Lenalidomide disease-specific toxicity profiles and potentially life-threatening adverse events support the consideration of diversity in starting doses. The aim of this study was to conduct a population pharmacokinetic analysis of lenalidomide in multiple myeloma patients to identify and evaluate non-studied covariates that could be used for dose individualization. METHODS: Blood samples were collected from 15 multiple myeloma patients. Nonlinear mixed-effects modeling was used to develop a population pharmacokinetic model and perform covariate analysis...

OBJECTIVE: Apparent life-threatening events (ALTEs), often accompanied by choking, have been hypothesized to cause subdural hemorrhages (SDH), retinal hemorrhages, and brain injury. If the choking/ALTE hypothesis were true, children who present with ALTE and SDH would have fewer extracranial injuries suspicious for abuse than those with SDH and no ALTE. We aimed to compare the prevalence of suspicious extracranial injuries in children who have ALTE-associated SDH to those with non-ALTE SDH...

Neonatal arterial ischemic stroke (NAIS) is a rare event that occurs in approximately one in 5000 term or close-to-term infants. Most affected infants will present with seizures. Although a well-recognized clinical entity, many questions remain regarding diagnosis, risk factors, treatment, and follow-up modalities. In the absence of a known pathophysiological mechanism and lack of evidence-based guidelines, only supportive care is currently provided. To address these issues, a French national committee set up by the French Neonatal Society (Société française de néonatologie) and the national referral center (Centre national de référence) for arterial ischemic stroke in children drew up guidelines based on an HAS (Haute Autorité de santé [HAS]; French national authority for health) methodology...
