Pore-forming proteins (PFPs) are of special interest because of the association of their activity with the disruption of the membrane impermeability barrier and cell death. They generally convert from a monomeric, soluble form into transmembrane oligomers that induce the opening of membrane pores. The study of pore formation in membranes with molecular detail remains a challenging endeavor because of its highly dynamic and complex nature, usually involving diverse oligomeric structures with different functionalities...

PURPOSE: Constitutional mismatch repair deficiency syndrome (CMMRD) is a lethal cancer predisposition syndrome characterized by early-onset synchronous and metachronous multiorgan tumors. We designed a surveillance protocol for early tumor detection in these individuals. PATIENTS AND METHODS: Data were collected from patients with confirmed CMMRD who were registered in the International Replication Repair Deficiency Consortium. Tumor spectrum, efficacy of the surveillance protocol, and malignant transformation of low-grade lesions were examined for the entire cohort...

Coronavirus disease-2019 (COVID-19) related to Coronavirus-2 (SARS-CoV-2) is a worldwide health concern. Despite the majority of patients will evolve asymptomatic or mild-moderate upper respiratory tract infections, 20% will develop severe disease. Based on current pathogenetic knowledge, a severe COVID-19 form is mainly a hyperinflammatory, immune-mediated disorder, triggered by a viral infection. Due to their particular immunological features, pregnant women are supposed to be particularly susceptible to complicate by intracellular infections as well as immunological disturbances...

Patrick D Shaw Stewart, Julia L Bach
This review seeks to explain three features of viral respiratory illnesses that have perplexed generations of virologists: (1) the seasonal timing of respiratory illness and the rapid response of outbreaks to weather, specifically temperature; (2) the common viruses causing respiratory illness worldwide, including year-round disease in the Tropics; (3) the rapid arrival and termination of epidemics caused by influenza and other viruses. The inadequacy of the popular explanations of seasonality is discussed, and a simple hypothesis is proposed, called temperature dependent viral tropism (TDVT), that is compatible with the above features of respiratory illness...

BACKGROUND: Children's healthy development is important. While governmental public assistance benefits financially troubled families, it cannot compensate for a lack of social support. Single-parenthood is a health risk factor for children owing to low-income-associated food insecurity and stress. No study has investigated the association between single-parenthood and health status in children from families receiving public assistance. This study aimed to examine the association between single-parent households and children's health among public assistance recipients in Japan by using linkage data of two municipal public assistance databases and administrative medical assistance data...

BACKGROUND: An acute upper respiratory tract infection (URI) is the most common disease worldwide, irrespective of age or sex. This study aimed to evaluate the short-term effect of diurnal temperature range (DTR) on emergency room (ER) visits for URI in Seoul, Korea, between 2009 and 2013. METHODS: Daily ER visits for URI were selected from the National Emergency Department Information System, which is a nationwide daily reporting system for ER visits in Korea. URI cases were defined according to International Classification of Diseases, 10th Revision codes J00-J06...

Mucin-5AC (MUC5AC) is a major secreted mucin in pathogenic airways. To determine its role in mucus-related airway disorders, Muc5ac -deficient ( Muc5ac-/- ) and wild-type ( Muc5ac+/+ ) mice were compared in bleomycin-induced pulmonary fibrosis, respiratory syncytial virus (RSV) disease, and ozone toxicity. Significantly greater inflammation and fibrosis by bleomycin were developed in Muc5ac-/- lungs compared to Muc5ac+/+ lungs. More severe mucous cell metaplasia in fibrotic Muc5ac-/- lungs coincided with bronchial Muc2 , Muc4 , and Muc5b overexpression...

COVID-19 has not spared a single system in the human body. Although acute respiratory failure culminating sometimes in death remains the most common manifestation of severe infection, hypercoagulability leading to deep vein thrombosis (DVT), pulmonary embolism (PE), and stroke have also been identified widely. Here, we describe a young patient with a COVID-19 infection who developed right basilic vein thrombosis. This case demonstrates how thrombosis can occur in uncommon sites and how clinicians should be vigilant for thrombotic complications in both the inpatient and outpatient settings...

Follicular bronchiolitis is a rare pulmonary disorder characterized by the presence of multiple hyperplastic lymphoid follicles with a peribronchiolar distribution. An 11-year-old girl with total atelectasis of the right middle lobe (RML) and diffuse multiple small nodules at both lung bases presented to our hospital with frequent upper respiratory infections and pneumonia. The disease progressed during a 3-month period of macrolide therapy, and thoracoscopic biopsy with lobectomy of the atelectatic RML was performed...

Objective: Investigation of the safety, tolerability, and treatment effect of nusinersen treatment in non-ambulatory adults with spinal muscular atrophy (SMA). Methods: Non-ambulatory individuals, aged 18 years or older with genetically confirmed 5q SMA were enrolled. In participants with spinal fusion, fluoroscopy guided cervical C1-C2 lateral approach was used. Outcomes at 2, 6, 10, and 14 months post-treatment were compared with baseline assessment. Forced vital capacity (FVC) was the primary outcome, and RULM, HFMSE, the modified SMA-FRS, and ulnar nerve electrophysiology [compound muscle action potential (CMAP), single motor unit size, and motor unit number] were secondary...

Performance and control of upright bipedal posture requires a constant and dynamic integration of relative contributions of different sensory inputs (i. e., sensory reweighting) to enable effective adaptations as individuals face environmental changes and perturbations. Children with gymnastic experience showed balance performance closer to that of adults during and after proprioceptive alteration than children without gymnastic experience when their center of pressure (COP) was analyzed. However, a particular COP sway can be achieved through performing and coordinating different postural movements...

The coronavirus disease of 2019 (COVID-19) is caused by the severe acute respiratory syndrome coronavirus-2 (SARS CoV-2), that already appeared as a global pandemic. Presentation of the disease often includes upper respiratory symptoms like dry cough, dyspnea, chest pain, and rhinorrhea that can develop to respiratory failure, needing intubation. Furthermore, the occurrence of acute and subacute neurological manifestations such as stroke, encephalitis, headache, and seizures are frequently stated in patients with COVID-19...

Rhinoviruses (RV), especially Human rhinovirus (HRVs) have been accepted as the most common cause for upper respiratory tract infections (URTIs). Pleconaril, a broad spectrum anti-rhinoviral compound, has been used as a drug of choice for URTIs for over a decade. Unfortunately, for various complications associated with this drug, it was rejected, and a replacement is highly desirable. In silico screening and prediction methods such as sub-structure search and molecular docking have been widely used to identify alternative compounds...

INTRODUCTION: Nowadays, acute respiratory infection (ARI) is the most common cause of high morbidity and mortality rate in children. ARI is defined as an infection either in the upper or lower respiratory tract that lasts for 14 days and caused by either viruses or bacteria. The incidence of ARI in 2017 is 20.54%, with the most prominent characteristic in children aged 1 to 4 years. Factors that affect ARI frequency are gender, birth weight, nutritional status, immunization status, vitamin A status, exclusive breastfeeding, smoke exposure, family income, and mother's formal education...
