Human Joint Angle Estimation Using Deep Learning-Based Three-Dimensional Human Pose Estimation for Application in a Real Environment.

Human pose estimation (HPE) is a technique used in computer vision and artificial intelligence to detect and track human body parts and poses using images or videos. Widely used in augmented reality, animation, fitness applications, and surveillance, HPE methods that employ monocular cameras are highly versatile and applicable to standard videos and CCTV footage. These methods have evolved from two-dimensional (2D) to three-dimensional (3D) pose estimation.

Potential forensic application of receptor for advanced glycation end products (RAGE) and aquaporin 5 (AQP5) as novel biomarkers for diagnosis of drowning.

Drowning is the most common cause of unnatural death worldwide. There is no single biomarker to diagnose drowning, so the diagnosis of drowning is one of the most difficult tasks in forensic medicine. Especially, distinguishing a victim of drowning from a body disposed of in water following death remains a problem.

Evaluation of disseminated intravascular coagulation scores in critically ill pediatric patients with septic shock.

Purpose: To evaluated the outcome predictability of DIC scores in critically ill children with septic shock.

Materials And Methods: Pediatric patients with septic shock who were admitted to the pediatric intensive care unit of a tertiary care children's hospital between January 2013 and December 2017 were enrolled. We analyzed the association between DIC and clinical outcomes.

Elevated central venous pressure is associated with increased mortality in pediatric septic shock patients.

Background: Central venous pressure (CVP) is an important factor affecting capillary blood flow, and it is associated with poor outcomes in adult septic shock patients. However, whether a similar association exists in pediatric patients remains unclear.

Methods: We retrospectively analyzed data from patients admitted to our pediatric intensive care unit (PICU) between February 2009 and July 2015.

The effectiveness of anti-biofilm and anti-virulence properties of dihydrocelastrol and dihydrocelastryl diacetate in fighting against methicillin-resistant Staphylococcus aureus.

Human pathogens have readily been converted into multidrug-resistant pathogens, such as methicillin-resistant Staphylococcus aureus (MRSA), because of the long-term use of conventional antibiotics. In addition, the biofilms formed by S. aureus cells are especially problematic and are related to the persistence of chronic infections because they constitute a major mechanism of promoting tolerance to diverse antimicrobial agents.

A rapid nuclear staining test using cationic dyes contributes to efficient STR analysis of telogen hair roots.

Telogen hairs presented in the crime scene are commonly encountered as trace evidence. However, short tandem repeat (STR) profiling of the hairs currently have low and limited use due to poor success rate. To increase the success rate of STR profiling of telogen hairs, we developed a rapid and cost-effective method to estimate the number of nuclei in the hair roots.

Factors Associated With Mortality in Continuous Renal Replacement Therapy for Pediatric Patients With Acute Kidney Injury.

Objectives: To analyze the epidemiology of pediatric acute kidney injury requiring continuous renal replacement therapy and identify prognostic factors affecting mortality rates.

Design: Retrospective analysis.

Setting: PICU of a tertiary medical center.

Microbiota Composition and Pulmonary Surfactant Protein Expression as Markers of Death by Drowning.

Pathological diagnosis of drowning remains a challenge for forensic science, because of a lack of pathognomonic findings. We analyzed microbiota and surfactant protein in the lungs for a novel diagnosis of drowning. All rats were divided into drowning, postmortem submersion, and control groups.

Activity of novel inhibitors of Staphylococcus aureus biofilms.

Staphylococcus aureus is one of the most important pathogens causing chronic biofilm infections. These are becoming more difficult to treat owing to drug resistance, particularly because S. aureus biofilms limit the efficacy of antimicrobial agents, leading to high morbidity and mortality.

Ultrasonography features of medullary thyroid cancer as predictors of its biological behavior.

Background Although there are many well-known prognostic predictors of medullary thyroid carcinoma (MTC), the ultrasonography (US) findings of MTC have not been sufficiently validated in this regard. Purpose To investigate the US findings of MTC and their relationship with the biological behavior of MTC. Material and Methods The US findings and clinical and pathology records of 123 MTC nodules from 108 patients were retrospectively analyzed at two tertiary referral hospitals.

Association between the lactate/albumin ratio and mortality in pediatric septic shock patients with underlying chronic disease: retrospective pilot study.

Background: We aimed to evaluate the ability of the lactate/albumin ratio to predict mortality in pediatric septic shock patients.

Methods: Retrospective analysis of the medical records of a pediatric intensive care unit. The study cohort comprised 90 pediatric septic shock patients admitted from February 2012 to May 2015.

Radiofrequency treatment enhances the catalytic function of an immobilized nanobiohybrid catalyst.

Biocatalysis, the use of enzymes in chemical transformation, has undergone intensive development for a wide range of applications. As such, maximizing the functionality of enzymes for biocatalysis is a major priority to enable industrial use. To date, many innovative technologies have been developed to address the future demand of enzymes for these purposes, but maximizing the catalytic activity of enzymes remains a challenge.

Early blood lactate area as a prognostic marker in pediatric septic shock.

Purpose: We attempted to evaluate whether the early lactate area is useful as an early prognostic marker of mortality in pediatric septic shock patients.

Methods: We performed a retrospective study of pediatric patients with septic shock who were admitted to the pediatric intensive care unit of Asan Medical Center, Seoul, Korea. Serial arterial lactate levels were obtained immediately and then every 6 h after admission for a total of 24 h.

Purification of His-tagged proteins using Ni2+-poly(2-acetamidoacrylic acid) hydrogel.

In this study, a new matrix for immobilized metal affinity chromatography (IMAC) using poly(2-acetamidoacrylic acid) (PAAA) hydrogels complexed with Ni(2+) was developed for the purification of the recombinant histidine-tagged green fluorescence protein (His6-GFP). The Ni(2+)-complexed PAAA hydrogel was prepared by polymerizing 2-acetamidoacrylic acid (AAA) and 2,2'-[(1,4-dioxo-1,4-butanediyl)diamino] bis(2-propenoic acid) (DBDBPA) with potassium persulfate in DMSO, followed by Ni(2+) complexation. Confocal laser scanning microscopy was used to determine the binding of His6-GFP to the Ni(2+)-PAAA hydrogel in three-dimensional space.

Novel atmospheric pressure plasma device releasing atomic hydrogen: reduction of microbial-contaminants and OH radicals in the air.

A novel atmospheric pressure plasma device releasing atomic hydrogen has been developed. This device has specific properties such as (1) deactivation of airborne microbial-contaminants, (2) neutralization of indoor OH radicals and (3) being harmless to the human body. It consists of a ceramic plate as a positive ion generation electrode and a needle-shaped electrode as an electron emission electrode.
