  SRs of CT/MRI findings for hilar cholangiocarcinoma can reveal more predefined key features, provide more sufficiency of information, and yield higher satisfaction levels, in comparison with NRs.

We present the case of a 21-year-old woman presenting with urticarial rash, arthralgias, and elevated inflammatory markers. She has been suffering these symptoms for 2 years and was treated with antihistamines, omalizumab, steroids, and non-steroidal anti-inflammatory drugs (NSAIDs) without success. After an extensive diagnostic workout, we suspected SchS even without monoclonal gammopathy, and started Anakinra 100 mg daily with a dramatic response and achieving complete remission after 48 h of the beginning of the treatment, so we decided to confirm SchS diagnosis. We performed a search of the literature and found seven more cases of patients diagnosed with SchS without monoclonal gammopathy at the presentation. Five were treated with IL-1 blocking therapies and all achieved remission. We, therefore, prompt the possible role of IL-1 blockade therapy remission as support in diagnosing SchS without monoclonal gammopathy.Numerous studies of native proteins have been reported on protein folding in this half century. Recently, post-translationally modified proteins are also focused on protein folding. However, it is still difficult to prepare such types of proteins because it requires not only the chemical but also the recombinant techniques. Native chemical ligation (NCL) is a powerful technique for producing target proteins when combined with recombinant techniques, such as expressed protein ligation (EPL). NCL basically requires an N-terminal peptide with a thioester and a C-terminal peptide which should possess a Cys residue at the N-terminus. Numerous efforts have been made to prepare N-terminal peptides carrying a thioester or a derivative thereof. However, a method for preparing C-terminal Cys-peptides with post-translational modifications has not been well developed, making it difficult to prepare such C-terminal Cys-peptides, except for chemical syntheses or enzymatic digestion. We report here on the development of a convenient technique that involves acid hydrolysis at the -Asp-Cys- sequence, to effectively obtain a C-terminal peptide fragment that can be used for any protein synthesis when combined with EPL, even under denatured conditions. Thus, this chemical digestion strategy permits the NCL strategy to be dramatically accelerated for protein syntheses in which post-translational modifications, such as glycosylation, phosphorylation, etc. are involved. In addition, this method should be useful to prepare the post-translationally modified proteins for protein folding.
  Elderly living alone in South Korea report higher rates of psychological distress compared to the population at large. Using a person-centered approach, the aim of the present study was to identify the latent profiles of South Korean elderly living alone based on self-esteem, life satisfaction, and depression.
 
  Latent profile analysis (LPA) was conducted based on data of 1545 older age individuals living alone. In addition, we examined significant factors that differentiate the observed profiles using multinomial logistic regression analysis.
 
  We identified five profiles "extremely depressed (n= 44, 2.9%)," "severely depressed (n= 169, 10.9%)," "mildly depressed (n= 529, 34.2%)," "low life satisfaction (n= 128, 8.3%)," and "positive adaptation (n= 675, 43.7%)." In addition, results of multinomial logistic regression analysis indicated that males (OR 1.69; 95% CI 1.02-2.81), and elderly with lower income (OR 0.86; 95% CI 0.81-0.91), lower level of physical health (OR 0.43; 95% CI 0.33-0.57), and lower sociderly living alone to enhance their quality of life. Furthermore, interventions that aim to maintain social networks are tantamount in order to prevent isolation in the elderly living alone.The lung is an organ that is directly exposed to the external environment. Given the large surface area and extensive ventilation of the lung, it is prone to exposure to airborne substances, such as pathogens, allergens, chemicals, and particulate matter. Highly elaborate and effective mechanisms have evolved to protect and maintain homeostasis in the lung. Despite these sophisticated defense mechanisms, the respiratory system remains highly susceptible to environmental challenges. Because of the impact of respiratory exposure on human health and disease, there has been considerable interest in developing reliable and predictive in vitro model systems for respiratory toxicology and basic research. Human air-liquid-interface (ALI) organotypic airway tissue models derived from primary tracheobronchial epithelial cells have in vivo-like structure and functions when they are fully differentiated. The presence of the air-facing surface allows conducting in vitro exposures that mimic human respiratory exposures. Exposures can be conducted using particulates, aerosols, gases, vapors generated from volatile and semi-volatile substances, and respiratory pathogens. Toxicity data have been generated using nanomaterials, cigarette smoke, e-cigarette vapors, environmental airborne chemicals, drugs given by inhalation, and respiratory viruses and bacteria. Although toxicity evaluations using human airway ALI models require further standardization and validation, this approach shows promise in supplementing or replacing in vivo animal models for conducting research on respiratory toxicants and pathogens.
