RESUMEN

Effective multi-object tracking is still challenging due to the trade-off between tracking accuracy and speed. Because the recent multi-object tracking (MOT) methods leverage object appearance and motion models so as to associate detections between consecutive frames, the key for effective multi-object tracking is to reduce the computational complexity of learning both models. To this end, this work proposes global appearance and motion models to discriminate multiple objects instead of learning local object-specific models. In concrete detail, it learns a global appearance model using contrastive learning between object appearances. In addition, we learn a global relation motion model using relative motion learning between objects. Moreover, this paper proposes object constraint learning for improving tracking efficiency. This study considers the discriminability of the models as a constraint, and learns both models when inconsistency with the constraint occurs. Therefore, object constraint learning differs from the conventional online learning for multi-object tracking which updates learnable parameters per frame. This work incorporates global models and object constraint learning into the confidence-based association method, and compare our tracker with the state-of-the-art methods on public available MOT Challenge datasets. As a result, we achieve 64.5% MOTA (multi-object tracking accuracy) and 6.54 Hz tracking speed on the MOT16 test dataset. The comparison results show that our methods can contribute to improve tracking accuracy and tracking speed together.

RESUMEN

BACKGROUND: Exposure to environmental chemicals has been linked with endothelial dysfunction, which is a leading cause of human diseases, including atherosclerosis. Permethrin is a frequently used synthetic pyrethroid insecticide for which longer exposure may cause toxicity in several types of tissues and the development of metabolic diseases, including atherosclerosis, obesity and diabetes. The present study was designed to evaluate the potential adverse effect of permethrin on the function and activity of human endothelial cells. RESULTS: Permethrin was found to repress migration and tube formation by human umbilical vein endothelial cells (HUVECs) in a dose-dependent manner, as well as to significantly repress their viability after 24 and 48 h of treatment. Furthermore, increased reactive oxygen species (ROS) production was observed in cells treated with permethrin, and the permethrin-induced repression of cell viability was ROS-dependent. Permethrin did not influence apoptosis, necrosis or mitochondrial membrane potential in HUVECs. CONCLUSION: The results of the present study suggest that permethrin represses angiogenesis and viability through ROS-dependent and cell growth-, apoptosis- and necrosis-independent means. © 2022 Society of Chemical Industry.

RESUMEN

AIMS: This study aimed to investigate the efficacy and safety of mirabegron for Parkinsonism patients with overactive bladder (OAB) symptoms in a randomized, placebo-controlled, multicenter study. MATERIALS AND METHODS: Inclusion criteria are Parkinsonism with OAB symptoms for 4 weeks or more, OAB symptom score (OABSS) questionnaire scores greater than 2, and OABSS urgency question scores greater than 1. After a 2-week wash-out period, the patients were randomized into placebo and mirabegron groups at visit 2. Visit 3 was performed after 4 weeks of medication. Mirabegron was prescribed to the two groups for the rest of the study period at visit 4. RESULT: The mean age was 68.1 ± 8.1 years and 72 males and 64 females were included. A total of 136 patients were screened, 117 patients were randomized, and 25 patients dropped out. The OABSS scores were significantly different between the two groups at Weeks 4 and 8. The OABSS scores became the same in the two groups at Week 12 (visit 5). The postvoid residual urine volume showed a mild increase to 64 ml in the mirabegron group compared to the placebo group at visit 4. Adverse events occurred in 27 patients (23.1%). The degree was mild in 26 cases (78.8%), moderate in five (15.2%), and severe in two (6.1%). Only 13 cases (39.4%) showed medication-related adverse events. Acute urinary retention occurred in a single case. The treatment satisfaction questionnaires showed no significant differences between the two groups. CONCLUSION: Mirabegron was effective in treating OAB symptoms in patients with Parkinsonism with acceptable adverse events.

RESUMEN

Colon cancer (CC) is considered a high-risk cancer in developed countries. Its etiology is correlated with a high consumption of red meat and low consumption of plant-based foods, including whole grains. Sorghum bran is rich in polyphenols. This study aimed to determine whether different high-phenolic sorghum brans suppress tumor formation in a genetic CC rodent model and elucidate mechanisms. Tissue culture experiments used colorectal cancer cell lines SW480, HCT-116 and Caco-2 and measured protein expression, and protein activity. The animal model used in this study was APC Min+/mouse model combined with dextram sodium sulfate. High phenolic sorghum bran extract treatment resulted in the inhibition of proliferation and induced apoptosis in CC cell lines. Treatment with high phenolic sorghum bran extracts repressed TNF-α-stimulated NF-κB transactivation and IGF-1-stimulated PI3K/AKT pathway via the downregulation of ß-catenin transactivation. Furthermore, high-phenolic sorghum bran extracts activated AMPK and autophagy. Feeding with high-phenolic sorghum bran for 6 weeks significantly suppressed tumor formation in an APC Min/+ dextran sodium sulfate promoted CC mouse model. Our data demonstrates the potential application of high-phenolic sorghum bran as a functional food for the prevention of CC.

RESUMEN

Sorghum is one of the most widely cultivated crops, and is used in foods, domestic animal feedstuffs, alcohol production, and biofuels. Recently, many research groups have demonstrated that sorghum contains various components that are strongly associated with the prevention of major human chronic diseases such as obesity, diabetes, atherosclerosis, cancer, and inflammation. However, to use sorghum more widely as a food for the potential prevention and treatment of human chronic diseases, more studies will be required to elucidate the biological mechanisms. In this review paper, we highlight multiple findings to propose a mechanistic link between sorghum consumption and reduced risk of chronic diseases. © 2020 Society of Chemical Industry.

RESUMEN

PURPOSE: Postmicturition dribbling (PMD) is a stressful symptom in middle-aged men characterized by urinary leakage after the completion of normal voiding. Appropriate treatments have not yet been introduced. This study assessed the efficacy of treatment of PMD with 75 mg udenafil daily. MATERIALS AND METHODS: The study included 138 men with regular sexual lifestyles. The Hallym PMD questionnaire (HPMDQ) was used to assess PMD symptoms. After all basic examinations, patients were randomly assigned to either udenafil or placebo. Patients completed the surveys, uroflowmetry (UFM), a bladder scan, and the paper test during the follow-up visit. RESULTS: The mean age of the patients was 57.6 years. PMD with one of every three urinations was experienced by 59 patients (42.8%), whereas 45 patients (32.6%) experienced PMD with two of every three urinations. PMD with every urination was experienced by 34 patients (24.6%). More than half of the patients (89 patients, 65.4%) indicated that persistent PMD symptoms would likely result in moderate to severe discomfort in their daily activities. As time passed, the udenafil group showed significant improvement in PMD symptoms (p = 0.001). CONCLUSION: Udenafil 75 mg once daily can be an effective treatment for patients with PMD symptoms.

RESUMEN

BACKGROUND: Demographic change and advances in technology affect transurethral surgery and outpatient procedures in the urologic field. There are few population-based studies that accurately assess the trend of transurethral surgery and outpatient procedures including diagnostic tests. We investigated the recent epidemiologic trends in transurethral surgeries and urological outpatient procedures from 2009 to 2016 in Korea using the entire population-based cohort. METHODS: We analyzed medical service claim data of transurethral surgery, urological outpatient procedures submitted by medical service providers from the Health Insurance Review and Assessment Service from 2009 to 2016. RESULTS: Transurethral ureter surgery increased by 134.9% from 14,635 in 2009 to 34,382 in 2016 (B = 2,698; R² = 0.98; P < 0.001). The transurethral bladder surgery increased by 65.5% from 12,482 in 2009 to 20,658 in 2016 (B = 1,149; R² = 0.97; P < 0.001). Over the 8-years period, there were not significant changes in transurethral prostate (B = 43; R² = 0.04; P = 0.617) and urethral surgery (B =-12; R² = 0.18; P = 0.289). The significantly increasing trends in cystoscopy (B = 5,260; R² = 0.95; P < 0.001) and uroflowmetry (B = 53,942; R² = 0.99; P < 0.001) were observed during the 8-year period. There was no difference in bladder catheterization during the 8-year period. Urodynamic study (UDS: B =-2,156; R² = 0.77; P = 0.003) and electrical stimulation treatment (EST: B =-1,034; R² = 0.87; P < 0.001) significantly decreased. CONCLUSION: In Korea, transurethral ureter surgery and transurethral bladder surgery have been continuously increasing. Transurethral prostate surgery and transurethral urethral surgery remained constant with no increase or decrease. Cystoscopy and uroflowmetry continue to increase, while UDS and EST continue to decrease.

RESUMEN

Epithelial specific ETS-1 (ESE-1) belongs to the E26 transformation-specific transcription factor superfamily and is of great interest as a potential target for managing several types of cancer. Despite its clinical significance, the documented effects of ESE-1 on cancer development and progression are contradictory and its underlying biological mechanism of action remains elusive. The objectives of this study are to investigate whether ESE-1 is a tumor suppressor and to identify dietary anti-cancer compound to activate ESE-1 expression in human colon cancer model. ESE-1 knockout and xenograft mouse models were used to examine the effect of ESE-1 in colon tumorigenesis. Stable human colon cancer cell lines were used for in vitro mechanistic studies. ESE-1 knockout in mice increased azoxymethane (AOM)-induced and dextran sulfate sodium (DSS)-promoted formation of aberrant crypt foci (ACF). Conversely, overexpression of ESE-1 suppressed tumorigenicity in a xenograft mouse study, and repressed anchorage-independent growth and migration/invasion in human colon cancer cells. Full length ESE-1 localized abundantly in the nucleus, and internal deletion of nuclear localization sequence 2 (NLS2) reduced nuclear ESE-1. Three lysine residues (318 KKK320 ) in the NLS2 determine its nuclear localization. We identified epigallocatechin-3-gallate (EGCG) that acts as a transcriptional activator of ESE-1 in human colon cancer cells. These findings propose a novel and promising molecular target of dietary anti-cancer compounds for prevention of colon cancer.

RESUMEN

OBJECTIVES: To compare the effects of taking tadalafil 5 mg and placebo once daily on post-micturition dribble (PMD) in men with lower urinary tract symptoms (LUTS). PATIENTS AND METHODS: Our prospective, randomized, double-blind, placebo-controlled, multicentre trial enrolled 102 men with PMD and other LUTS. PMD was assessed using the Hallym Post-Micturition Dribble Questionnaire (HPMDQ) and according to PMD volume. Over a 12-week period, patients took either tadalafil 5 mg (n = 51) or placebo (n = 51) once daily and their HPMDQ and PMD volume results were evaluated. Adverse events (AEs) were also reported. RESULTS: Over the course of 12 weeks, total HPMDQscores and PMD volumes improved significantly more in the tadalafil group than in the placebo group (reduction of total HPMDQ score of ≥2 points in the tadalafil and placebo group in 68.8% and 31.9% of patients (P < 0.001) and decreased mean PMD volume in the tadalafil and placebo group at 0.48 mL and 0.22  mL, respectively (P = 0.046). Specifically, PMD frequency decreased and quality of life increased significantly more in the tadalafil group than in the placebo group (P = 0.029 and P < 0.001, respectively). Furthermore, 66.7% of the tadalafil group reported moderate and significant PMD improvement, whereas only 4.2% reported that tadalafil was ineffective. Treatment-emergent AEs did not significantly differ between the groups (all P > 0.05), and no serious AEs were observed. CONCLUSION: Taking tadalafil 5 mg once daily reduced PMD symptom severity and PMD volume in men with PMD, without inducing serious AEs, more effectively than placebo, suggesting that taking tadalafil 5 mg once daily may be an effective and well-tolerated PMD treatment.

RESUMEN

BACKGROUND: Studies about the clinical utility of fillers on penile augmentation (PA) are lacking. Furthermore, no randomized study has compared the utilities of fillers. AIM: To compare the efficacy and safety between hyaluronic acid (HA) and polylactic acid (PLA) filler injection for PA. METHODS: This prospective, randomized patient/evaluator-blind, comparative multicenter study consisted of an initial 2-week baseline period and 48-week patient/evaluator-blind post-injection period. 72 patients with small penis syndrome were enrolled from 3 institutions between March-July 2016. Patients were divided into 2 groups: the HA group, comprising 36 patients injected with HA, and the PLA group, comprising 36 patients injected with PLA. MAIN OUTCOME MEASURES: Penile girth and satisfaction were assessed at baseline and at 4, 12, 24, and 48 weeks after injection. RESULTS: Penile girth increases adequately lasted ≤48 weeks in both groups (16.95 ± 10.53 and 13.49 ± 9.98 mm of mean increase in the HA and PLA groups, respectively; P < .001). The mean penile girth increase in the HA group was significantly greater than that in the PLA group at 4 weeks (P < .001). Subsequently, it gradually decreased and was no longer significantly different at 48 weeks (P = .075). Satisfaction levels increased after injection and were maintained ≤48 weeks. No significant differences were observed in the overall satisfaction level between the groups (P > .05). Filler injection-related adverse events were mild and transient and occurred in 1 and 3 patients in the HA and PLA groups, respectively. CLINICAL IMPLICATIONS: This study provides an overview of the efficacy and safety of HA and PLA fillers, which are the most commonly used soft tissue fillers for PA. STRENGTH AND LIMITATIONS: This study, to our knowledge, is the first to compare the efficacy and safety between different filler injections for human PA. However, it was impossible to perform a researcher-blinded trial because of the unique properties of fillers, and 31 patients (43.1%) were dropped during the study period. CONCLUSIONS: Both HA and PLA filler injections for PA led to a significant augmentative effect without serious adverse events and had clinically comparable efficacy and safety.
