Autophagy is an important degradative pathway that eliminates misfolded proteins and damaged organelles from cells. Autophagy is crucial for neuronal homeostasis and function. A lack of or deficiency in autophagy leads to the accumulation of protein aggregates, which are associated with several neurodegenerative diseases. Compared with non-neuronal cells, neurons exhibit rapid autophagic flux because damaged organelles or protein aggregates cannot be diluted in post-mitotic cells; because of this, these cells exhibit characteristic features of autophagy, such as compartment-specific autophagy, which depends on polarized structures and rapid autophagy flux. In addition, neurons exhibit compartment-specific autophagy, which depends on polarized structures. Neuronal autophagy may have additional physiological roles other than amino acid recycling. In this review, we focus on the characteristics and regulatory factors of neuronal autophagy. We also describe intracellular selective autophagy in neurons and its association with neurodegenerative diseases.

Purpose:
Single-incision cholecystectomy is a surgical method that offers comparable results to conventional laparoscopic cholecystectomy. However, a high risk of postoperative incisional hernia is an issue in single-incision cholecystectomy. This study evaluated the risk factors and incidences of incisional hernia after single-incision cholecystectomy and the advantage issue of using barbed suture material during wound closures.
Methods:
A total of 1,111 patients underwent laparoscopic or robotic single-incision cholecystectomy between March 2014 and February 2020 at our institution at CHA Bundang Medical Center. During this period, there were 693 patients who underwent wound closure with monofilament suture material (Monosyn 2-0; B. Braun) and the other 418 patients used barbed suture material (Stratafix 2-0; Ethicon).
Results:
The two patient groups were comparable in age, body mass index, and diagnosis. The total incidence of incisional hernia after single-incision cholecystectomy was 0.5% (five cases). All patients who developed incisional hernia were in the monofilament suture material group (0.7% vs. 0%, p = 0.021). The inf luence of predictive and possible risk factors on incisional hernia rate was analyzed. Among these factors, only old age was an independent predictive risk factor of incisional hernia.
Conclusion
Our study showed a low incidence of incisional hernia, all of which occurred in the monofilament suture material group. If technically appropriate, single-incision cholecystectomy does not appear to present a high incidence of hernia. Barbed suture material can be safely applied in wound closure showing comparable incisional hernia incidence to monofilament suture material.

BACKGROUND: Lung cancer is the most common cause of cancer-related death, and adenocarcinoma is the most common histologic subtype. MicroRNA is a small non-coding RNA that inhibits multiple target gene expression at the post-transcriptional level and is commonly dysregulated in malignant tumors. The purpose of this study was to analyze the expression of microRNA-374a (miR-374a) in lung adenocarcinoma and correlate its expression with various clinicopathological characteristics.METHODS: The expression level of miR-374a was measured in 111 formalin-fixed paraffin-embedded lung adenocarcinoma tissues using reverse transcription-quantitative polymerase chain reaction assays. The correlation between miR-374a expression and clinicopathological parameters, including clinical outcome, was further analyzed.RESULTS: High miR-374 expression was correlated with advanced pT category (chi-square test, p=.004) and pleural invasion (chi-square test, p=.034). Survival analysis revealed that patients with high miR-374a expression had significantly shorter disease-free survival relative to those with low miR-374a expression (log-rank test, p=.032).CONCLUSIONS: miR-374a expression may serve as a potential prognostic biomarker for predicting recurrence in early stage lung adenocarcinoma after curative surgery.

PURPOSE: This study aimed to investigate child abuse awareness and reporting intention among nursing and education students and correlations among the variables involved. METHODS: A cross-sectional study was conducted by administering an online questionnaire to 70 nursing college students and 70 education college students. Data were analyzed using descriptive statistics, t-test, chi-squared test, the Mann-Whitney U test, and Pearson's correlation in SPSS 21.0 (IBM, Armonk, NY). RESULTS: The mean score of child abuse awareness was 3.61±0.32 for nursing students and 3.60±0.36 for education students. The mean score of reporting intention was 5.65±0.90 for nursing students and 5.38±1.03 for education students. Females presented higher scores than males in the awareness of sexual abuse. The awareness of emotional abuse was higher in students who knew of reporting obligations or who had experienced abuse. Child abuse awareness and reporting intention were significantly positively correlated. Also, the number of times having received child abuse education was correlated with reporting intention in both mild and severe cases of abuse. CONCLUSION: Reporting intention is not only related to having received education, but also to the frequency of that education. Child abuse education is important to increase reporting intention and should be delivered repeatedly.

Purpose:
Mesenchymal epithelial transition (MET) is a proto-oncogene that encodes a heterodimerictransmembrane receptor tyrosine kinase for the hepatocyte growth factor. Aberrant METsignaling has been described in several solid tumors—especially non-small cell lung cancer—and is associated with tumor progression and adverse prognosis. As MET is a potentialtherapeutic target, information regarding its prevalence and clinicopathological relevanceis crucial.
Materials and Methods:
We investigated MET expression and gene amplification in 113 gallbladder cancers usingtissue microarray. Immunohistochemistry was used to evaluate MET overexpression, andsilver/fluorescence in situ hybridization (ISH) was used to assess gene copy number.
Results:
MET overexpression was found in 37 cases of gallbladder carcinoma (39.8%), and geneamplification was present in 17 cases (18.3%). MET protein expression did not correlatewith MET amplification. MET amplification was significantly associated with aggressive clinicopathologicalfeatures, including high histological grade, advanced pT category, lymphnode metastasis, and advanced American Joint Committee on Cancer stage. There was nosignificant correlation between any clinicopathological factors and MET overexpression. Nodifference in survival was found with respect to MET overexpression and amplification status.
Conclusion
Our data suggested that MET might be a potential therapeutic target for targeted therapyin gallbladder cancer, because MET amplification was found in a subset of tumors associatedwith adverse prognostic factors. Detection of MET amplification by ISH might be a usefulpredictive biomarker test for anti-MET therapy.

This study employed focus group interviews (FGIs) to evaluate the preparedness and training requirements for an emerging infectious disease response system in the Republic of Korea.Based on the FGIs, the critical role of interdepartmental cooperation in responding to emerging infectious diseases was identified, with agencies such as public health centers, police, and fire services playing key roles in scene control, decontamination, and patient transport. Frequent staff turnover and a lack of trained personnel at local government levels were significant challenges, necessitating the development of training materials for unskilled workers. Civil complaints, common during outbreaks, require public officials to be educated on legal frameworks and the management of patients’ rights. The absence of standardized procedures for managing patients, such as bed assignments considering underlying conditions and sample collection, underscores the need for comprehensive guidelines.Interviewees emphasized cross-departmental training, detailed manuals, and legal education to improve infectious disease response capabilities.
