Sex-specific differences in glucose metabolism and pancreatic function in streptozotocin-induced diabetic mice: The protective role of estrogen.

Sex differences significantly influence the pathophysiology of diabetes mellitus, with estrogen playing a protective role in glucose metabolism, insulin sensitivity, and beta-cell function. This study investigated sex-specific differences in glucose homeostasis, lipid metabolism, and pancreatic function in a streptozotocin (STZ)-induced diabetic mouse model. Eight-week-old male, female, and ovariectomized female C57BL/6J mice received STZ (40 mg/kg) for five consecutive days.

Classification of Depressive Symptoms Among Bereaved Families of Sewol Ferry Disaster Victims Using Latent Profile Analysis.

Objective: After the Sewol Ferry Disaster, most empirical studies on the bereaved families of victims conceptually categorized their depressive symptoms. However, the actual depressive features of bereaved families and the factors that influence such features remain unclear. Accordingly, this study aimed to categorize latent types of depression using latent profile analysis based on the sub-variables of the Patient Health Questionnaire-9 and identify the influencing factors for each type.

An ultraconserved snoRNA-like element in long noncoding RNA CRNDE promotes ribosome biogenesis and cell proliferation.

Cancer cells frequently upregulate ribosome production to support tumorigenesis. While small nucleolar RNAs (snoRNAs) are critical for ribosome biogenesis, the roles of other classes of noncoding RNAs in this process remain largely unknown. Here, we performed CRISPR interference (CRISPRi) screens to identify essential long noncoding RNAs (lncRNAs) in renal cell carcinoma (RCC) cells.

Real-time monitoring to predict depressive symptoms: study protocol.

Introduction: According to the World Health Organization, Depression is the fourth leading cause of global disease burden. However, traditional clinical and self-report assessments of depression have limitations in providing timely diagnosis and intervention. Recently, digital phenotyping studies have found the possibility of overcoming these limitations through the use of wearable-devices and smartphones.

Development and Validation of the COVID-19 Infection Fear Scale in a Collectivist Cultural Context: A Study From South Korea.

Objective: Understanding the specific fears associated with coronavirus disease-2019 (COVID-19), particularly within different cultural contexts, is crucial for developing effective mental health interventions. This study aims to develop and validate the COVID-19 Infection Fear Scale (CIFS) in a collectivist cultural context such as Korea.

Methods: A total of 1,002 adults aged 19 to 70 participated in an online survey in May 2020.

Molecular detection and genomic characterization of Samak Micromys paramyxovirus-1 and -2 in Micromys minutus, Republic of Korea.

Background: The discovery of viruses in small mammalian populations, particularly rodents, has expanded the family Paramyxoviridae. The overlap in habitats between rodents and humans increases the risk of zoonotic events, underscoring the importance of active surveillance. Rodent species, such as Apodemus agrarius, are natural hosts for Paramyxoviridae in the Republic of Korea (ROK).

An ultraconserved snoRNA-like element in long noncoding RNA promotes ribosome biogenesis and cell proliferation.

Cancer cells frequently upregulate ribosome production to support tumorigenesis. While small nucleolar RNAs (snoRNAs) are critical for ribosome biogenesis, the roles of other classes of noncoding RNAs in this process remain largely unknown. Here we performed CRISPRi screens to identify essential long noncoding RNAs (lncRNAs) in renal cell carcinoma (RCC) cells.

A non-canonical role for a small nucleolar RNA in ribosome biogenesis and senescence.

Cellular senescence is an irreversible state of cell-cycle arrest induced by various stresses, including aberrant oncogene activation, telomere shortening, and DNA damage. Through a genome-wide screen, we discovered a conserved small nucleolar RNA (snoRNA), SNORA13, that is required for multiple forms of senescence in human cells and mice. Although SNORA13 guides the pseudouridylation of a conserved nucleotide in the ribosomal decoding center, loss of this snoRNA minimally impacts translation.

Long-term adjuvant metronomic chemotherapy in a dog with recurrent maxillofacial osteosarcoma.

Osteosarcoma (OSA) is the most common malignant bone tumour in dogs; however, OSA of the maxilla is uncommon compared to appendicular OSA. Oral melanoma also commonly occurs in dogs with frequent distant metastasis. The role of adjuvant chemotherapy has been questioned in maxillary OSA and melanoma.

Induced interpretation bias affects free recall and episodic memory bias in social anxiety.

The combined effect of each cognitive bias, interpretation, attention, and memory bias, is known to play a causal role in the etiology and maintenance of social anxiety. However, little is known about how each type of bias (i.e.

Outbred Mice with Streptozotocin-Induced Diabetes Show Sex Differences in Glucose Metabolism.

Outbred mice (ICR) with different genotypes and phenotypes have been reported to be more suitable for scientific testing than inbred mice because they are more similar to humans. To investigate whether the sex and genetic background of the mice are important factors in the development of hyperglycemia, we used ICR mice and divided them into male, female, and ovariectomized female (FOVX) groups and treated them with streptozotocin (STZ) for five consecutive days to induce diabetes. Our results show that fasting blood glucose and hemoglobin A (HbA) levels were significantly higher in diabetes-induced males (M-DM) and ovariectomized diabetes-induced females (FOVX-DM) than in diabetes-induced females (F-DM) at 3 and 6 weeks after STZ treatment.

Time-Series Trends of Depressive Levels of Korean Adults During the 2020 COVID-19 Pandemic in South Korea.

Objective: This study aimed to observe the changes in people's depressive levels over 9 months since the coronavirus disease of 2019 (COVID-19) outbreak as well as to identify the predictors of people's depressive levels including COVID-19 infection fear in the context of South Korea in 2020.

Methods: For these purposes, four cross-sectional surveys were periodically implemented from March to December 2020. We randomly recruited 6,142 Korean adults (aged 19 to 70) by using a quota survey.

[CT and MR Imaging Findings of Structural Heart Diseases Associated with Sudden Cardiac Death].

Sudden cardiac death is an unexpected death originating from the heart that occurs within an hour of the onset of symptoms. The main cause of sudden cardiac death is arrhythmia; however, diagnosing underlying structural heart disease significantly contributes to predicting the long-term risk. Cardiovascular CT and MR provide important information for diagnosing and evaluating structural heart disease, enabling the prediction and preparation of the risk of sudden cardiac death.

Factors Related to Anxiety and Depression Among Adolescents During COVID-19: A Web-Based Cross-Sectional Survey.

Background: The coronavirus disease 2019 (COVID-19) outbreak and subsequent disease-containment measures (such as school closures) significantly affected the lives of adolescents. We evaluated the mental-health status and factors associated with anxiety and depression among South Korean adolescents.

Methods: A nationwide online survey was conducted to evaluate the mental-health status of South Korean adolescents during the COVID-19 pandemic.

Different outcomes of multiple sialadenitis involving the submandibular and zygomatic salivary glands in a Welsh Corgi dog.

A ten-year-old indoor, castrated male Cardigan Welsh Corgi () presented with the chief complaints of chronic vomiting, retching, hypersalivation, and bilateral submandibular masses for two months. The systemic examinations, including serum chemistry, radiography, ultrasonography, and fluoroscopy, were unremarkable. A fine-needle aspiration revealed bilateral submandibular sialadenitis.

Hemostatic Analysis of Simulated Envenomation Using Canine Blood: A Comparison of Thromboelastography and Classical Coagulation Tests.

Snake envenomation may lead to venom-induced consumptive coagulopathy (VICC), usually diagnosed by classical coagulation tests (CCTs), such as prothrombin time (PT) and activated partial thromboplastin time (aPTT). However, the results of CCTs are frequently normal in the initial stages, which may delay anti-venom treatments. Thromboelastography (TEG) is a point-of-care and real-time diagnostic tool that enables a comprehensive assessment of the coagulation process.
