is a valuable potential probiotic species with various proven health-beneficial effects. LM1001 strain was selected among ten strains of based on proteolytic activity on whey proteins. LM1001 produced higher concentrations of total free amino acids and branched-chain amino acids (Ile, Leu, and Val) than other strains.

Background: Androgenetic alopecia (AGA) is a common and chronic problem characterized by hair follicle miniaturization.

Aims: In this study, heat-treated Limosilactobacillus fermentum LM1020 (HT-LM1020) was investigated in human follicle dermal papilla cell (HFDPC), scalp tissue, and clinical trials for patients with AGA.

Patients/methods: Cell proliferation and the expression of cyclins and cyclin-dependent kinases (CDKs) were measured in HFDPC.

Article Synopsis
  • Probiotics like Lactobacillus gasseri LM1065 are live microorganisms that provide health benefits, and this particular strain was isolated from human breast milk and studied for its probiotic capabilities.
  • The research involved genome mapping and assessing its resistance to gastric conditions, adherence to gut cells, and safety, showing it tolerated harsh stomach environments and displayed beneficial adherence properties.
  • Additionally, the strain's cell-free supernatant (CFS) demonstrated antifungal effects against Candida albicans, highlighting its potential in preventing vaginal infections.

Purpose: Acne vulgaris is a common skin disease accompanied by chronic inflammation in the pilosebaceous follicles, resulting from excessive Cutibacterium acnes. This study aimed to investigate the inhibition of biofilm formation by C. acnes ATCC 6919 using heat-treated Pediococcus acidilactici LM1013 (HT-LM1013), previously isolated from the Korean traditional fermented alcoholic beverage-makgeolli, and its application as a leave-on-type product for patients with acne vulgaris.

Article Synopsis
  • Postbiotics are inactivated probiotics that are more stable and beneficial for use in food and medicine compared to regular probiotics.
  • The study focused on heat-treated LM1004 from kimchi, analyzing its fatty acid composition and immunostimulatory effects on macrophage cells, showing increased nitric oxide and cytokine production.
  • Results indicate that HT-LM1004 activates specific signaling pathways (MAPK and NF-κB), enhancing immune responses, which could help in developing new food and pharmaceutical products.

Active research on crack detection technology for structures based on unmanned aerial vehicles (UAVs) has attracted considerable attention. Most of the existing research on localization of cracks using UAVs mounted the Global Positioning System (GPS)/Inertial Measurement Unit (IMU) on the UAVs to obtain location information. When such absolute position information is used, several studies confirmed that positioning errors of the UAVs were reflected and were in the order of a few meters.

Rationale: One-lung ventilation (OLV) is essential for adequate visualization and exposure of the surgical site via a videoscopic approach. Although many instruments facilitating OLV are available, the choice is limited in pediatric patients.

Patient Concerns: A 4-year-old female (weight: 18.

Background: To evaluate the macular pigment optical density (MPOD) with age in the Korean population using the Macular Pigment Screener II (MPSII®).

Methods: One hundred and twenty-six eyes were retrospectively reviewed. MPOD was measured using MPSII®, which uses a heterochromatic flicker photometry method, and the estimated values were analyzed.

The purposes of this study were to develop the Yonsei Face Database (YFace DB), consisting of both static and dynamic face stimuli for six basic emotions (happiness, sadness, anger, surprise, fear, and disgust), and to test its validity. The database includes selected pictures (static stimuli) and film clips (dynamic stimuli) of 74 models (50% female) aged between 19 and 40. Thousand four hundred and eighty selected pictures and film clips were assessed for the accuracy, intensity, and naturalness during the validation procedure by 221 undergraduate students.

Background: Postoperative pancreatic fistula (POPF) is one of the most common and clinically relevant complications after distal pancreatectomy (DP), occurring in 5-40% of patients. Determining risk factors for this complication may aid in its prevention. This study sought to predict the development of POPF after DP preoperatively and objectively based on radiologic findings.

Background/aims: Laparoscopic cholecystectomy is the standard treatment for acute cholecystitis. Percutaneous cholecystostomy is an alternative treatment to resolve acute inflammation in patients with severe comorbidities. The purpose of this study is to determine the optimal timing of laparoscopic cholecystectomy after percutaneous cholecystostomy for the patients with acute cholecystitis.

In the present study, we tested the dominant notion that the processing of familiar faces takes place in an automatic, capacity-unlimited manner. To do so, we had participants perform the task of detecting their own face among others' nonfamiliar faces. Importantly, either all of the search stimuli were presented simultaneously or two different subsets of the stimuli were presented sequentially.

Background/purpose: Surgical resection is the only curative treatment for extrahepatic bile duct (EHBD) cancer, but guidelines for optimal resection margins have not yet been established. Therefore, the purpose of this study is to analyze the patterns of microscopic tumor spreads and their lengths according to gross morphology and to suggest optimal resection margins for EHBD cancer.

Methods: A total of 79 patients with EHBD cancers who underwent curative resection at Seoul National University Hospital between 2007 and 2010 were reviewed.

Background: In high-risk and unfit-for-surgery patients with acute cholecystitis (AC), treatment options are controversial. Few studies have reported the results of long-term follow-up. This study aimed to evaluate the clinical course of patients after removal of the percutaneous cholecystostomy (PC) catheter in high-risk patients with AC, time interval to relapse, and factors influencing relapse.
