Regulation of innate immune response by miRNAs up-regulated in Stevens-Johnson syndrome with severe ocular complications.

Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN) are severe mucocutaneous disorders characterized by extensive tissue necrosis; they are often accompanied by severe ocular complications (SOC). The regulatory role of microRNAs (miRNAs) in modulating immune responses in SJS/TEN is not fully understood, particularly in relation to chronic SOC. We explored the expression profiles of specific miRNAs and their potential impact on the regulation of key innate immune genes in patients with SJS/TEN with SOC.

Parasite infestations and infections of non-traditional pets and wild mammals: diagnosis and treatment.

Little is known about parasites in wild mammals kept as pets. For this study, fecal and skin/fur samples and ectoparasites from 55 wild and pet mammals attended at a veterinary clinic were evaluated. Opossums (Didelphis albiventris and Didelphis aurita) were parasitized by helminths (Aspidodera sp.

The hibernation promoting factor of Betaproteobacteria Comamonas testosteroni cannot induce 100S ribosome formation but stabilizes 70S ribosomal particles.

Bacteria use several means to survive under stress conditions such as nutrient depletion. One such response is the formation of hibernating 100S ribosomes, which are translationally inactive 70S dimers. In Gammaproteobacteria (Enterobacterales), 100S ribosome formation requires ribosome modulation factor (RMF) and short hibernation promoting factor (HPF), whereas it is mediated by only long HPF in the majority of bacteria.

Trust in governments, public health institutions, and other information sources as determinants of COVID-19 vaccine uptake behavior in Japan.

Objectives: Trust in governments and public institutions as a determinant of public health outcomes has gained increased attention since the COVID-19 pandemic. Provided historically low confidence in vaccines in Japan, investigating the role of trust in information sources and actual COVID-19 vaccination uptake behavior will be invaluable for future vaccine promotion policymaking. Therefore, the objective of this study was to elucidate the determinants of COVID-19 vaccination uptake and evaluate the relationship between trust in different information sources and COVID-19 vaccination behavior in Japan.

Understanding factors related to healthcare avoidance for menstrual disorders and menopausal symptoms: A cross-sectional study among women in Japan.

This study explored the factors associated with healthcare avoidance behavior for menstrual disorders and menopausal symptoms among women in Japan. Using data from a nationally representative cross-sectional online survey conducted in September 2022, responses from 4,950 women aged 25-59 were analyzed. This study applied binomial logistic regression models specifically to participants who reported having ever felt the need to seek healthcare assistance due to health issues related to menstruation and menopause.

Effects of human depopulation and warming climate on bird populations in Japan.

Quantifying biodiversity trends in economically developed countries, where depopulation, associated secondary succession, and climate warming are ongoing, provides insights for global biodiversity conservation in the 21st century. However, few studies have assessed the impacts of secondary succession and climate warming on species' population trends at a national scale. We estimated the population trends of common breeding bird species in Japan and examined the associations between the overall population trend and species traits with the nationwide bird count data on 47 species collected from 2009 to 2020.

Severe ocular complications of SJS/TEN and associations among pre-onset, acute, and chronic factors: a report from the international ophthalmology collaborative group.

We formed an international research collaboration that included Japan, South Korea, Brazil, Thailand, Taiwan, the UK, and the US (682 patients from 13 hospitals between 2005 and 2020), to better evaluate the role of race, ethnicity, and other risk factors in the pathophysiology of Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN). Ophthalmologists often see SJS/TEN patients with severe ocular complications (SOC; frequency 50% SJS/TEN patients) when the patients are referred to them in the chronic stage after the acute stage has passed. Global data were collected using a Clinical Report Form, capturing pre-onset factors, as well as acute and chronic ocular findings.

Differences in gene regulation by TLR3 and IPS-1 signaling in murine corneal epithelial cells.

Toll-like receptor 3 (TLR3) and interferon-beta promoter stimulator-1 (IPS-1) are associated with antiviral responses to double-stranded RNA viruses and contribute to innate immunity. We previously reported that conjunctival epithelial cell (CEC) TLR3 and IPS-1 pathways respond to the common ligand polyinosinic:polycytidylic acid (polyI:C) to regulate different gene expression patterns as well as CD11c + cell migration in murine-model corneas. However, the differences in the functions and the roles of TLR3 and IPS-1 remain unclear.

Topical Betamethasone Treatment of Stevens-Johnson Syndrome and Toxic Epidermal Necrolysis with Ocular Involvement in the Acute Phase.

Purpose: To clarify the importance of administering topical steroids for the treatment of Stevens-Johnson syndrome (SJS) / toxic epidermal necrolysis (TEN) with ocular involvement in the acute phase.

Design: Retrospective case series.

Methods: Using the medical records of acute SJS/TEN patients treated at the Kyoto Prefectural University of Medicine Hospital, Kyoto, Japan, between July 2006 and July 2017, the ocular findings, topical steroid dosage, systemic steroid dosage, and ocular sequelae were retrospectively examined.

The Discovery of Ribosomal Protein bL31 from : A Long Story Revisited.

Ribosomal protein bL31 in was initially detected as a short form (62 amino acids) using Kaltschmidt and Wittmann's two-dimensional polyacrylamide gel electrophoresis (2D PAGE), but the intact form (70 amino acids) was subsequently identified by means of Wada's improved radical-free and highly reducing (RFHR) 2D PAGE, which was consistent with the analysis of its encoding gene . Ribosomes routinely prepared from the K12 wild-type strain contained both forms of bL31. Δ cells, which lack protease 7, only contained intact bL31, suggesting that protease 7 cleaves intact bL31 and generates short bL31 during ribosome preparation from wild-type cells.

G‑CSF delays tooth extraction socket bone healing via the inhibition of bone turnover in mice.

Granulocyte colony-stimulating factor (G-CSF) regulates the survival, proliferation and differentiation of all cells in the neutrophil lineage, and is consequently used for neutropenic conditions. Upon G-CSF administration, osteoblasts and osteocytes are suppressed, and the support system allowing hematopoietic stem cells to remain in the microenvironment is diminished. The present study focused on and investigated G-CSF as a regulatory factor of bone remodeling.

Positive regulation of innate immune response by miRNA-let-7a-5p.

We have hypothesized that different factors are involved in the severity of ACD and AD because some but not all patients with atopic dermatitis (AD) present with allergic conjunctival disease (ACD) including severe types such as atopic keratoconjunctivitis (AKC) with/without giant papillae. We previously reported that plasma miR-628-3p was up-regulated in AD with severe ACD, but not in severe AD without severe ACD or in our healthy controls. In this study, to investigate the pathogenesis of AD with and without severe ACD, we performed comprehensive plasma miRNA analysis and studied the function of some miRNAs which were significantly up-regulated in ACD.

Susceptibility Genes and HLA for Cold Medicine-Related SJS/TEN with SOC.

We investigated the genetic predisposition for the pathogenesis of Stevens-Johnson syndrome/epidermal necrolysis with severe ocular complications (SJS/TEN with SOC). Cold medicines (CMs) including multi-ingredient cold-medications and non-steroidal anti-inflammatory drugs (NSAIDs) were implicated in the development of SJS/TEN with SOC. Studies on the association between HLA genotypes and CM-related SJS/TEN with SOC (CM-SJS/TEN with SOC) revealed an association with in the Japanese; it may be a marker in Koreans.

Risk factors for sepsis and effects of pretreatment with systemic steroid therapy for underlying condition in SJS/TEN patients: Results of a nationwide cross-sectional survey in 489 Japanese patients.

Background: Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN) are life-threatening severe cutaneous adverse reactions (SCARs). Sepsis has been shown to be the main cause of death in SJS/TEN. The European SCAR study reported that 14.
