Rice Bran Extract Suppresses High-Fat Diet-Induced Hyperlipidemia and Hepatosteatosis through Targeting AMPK and STAT3 Signaling.

Rice bran, a by-product of rice milling, is abundant in bioactive molecules and is highly recognized for its health-promoting properties, particularly in improving metabolic conditions. Building on this knowledge, we aimed to optimize the extraction conditions to maximize the functional efficacy of rice bran extract (RBE) and further validate its impact on lipid metabolism. We found that the optimized RBE (ORBE) significantly suppressed high-fat diet-induced weight gain, hyperlipidemia, and hepatosteatosis in mouse models.

Peli3 ablation ameliorates acetaminophen-induced liver injury through inhibition of GSK3β phosphorylation and mitochondrial translocation.

The signaling pathways governing acetaminophen (APAP)-induced liver injury have been extensively studied. However, little is known about the ubiquitin-modifying enzymes needed for the regulation of APAP-induced liver injury. Here, we examined whether the Pellino3 protein, which has E3 ligase activity, is needed for APAP-induced liver injury and subsequently explored its molecular mechanism.

Treating AO Type C2-3 Distal Humerus Fractures With the Anconeus Flap Transolecranon Approach.

We evaluated the outcomes of precontoured locking plate fixation with the anconeus flap transolecranon (AFT) approach to treating AO type C2-3 comminuted intra-articular distal humerus (IDH) fractures among active patients. Thirty-six patients (age <65 years) with IDH fractures treated with precontoured distal humerus locking plate fixation were divided into 2 groups: group 1 (n=18; transolecranon [TO] approach) and group 2 (n=18; AFT approach). The radiographic examination included assessments of implant failure, fracture site union, and olecranon osteotomy site union.

One-Dimensional Porous Li-Confinable Hosts for High-Rate and Stable Li-Metal Batteries.

Li-confinable core-shell hosts have been extensively studied because they mitigate Li dendrite growth and volume change by reducing the effective current density and storing Li inside the core space during consecutive cycling. However, despite these fascinating features, these hosts suffer from unwanted Li growth on their surface (i.e.

Associations of walking and resistance training with chronic low back pain in older adults: A cross-sectional analysis of Korean National Health and Nutrition Examination Survey data.

Physical activities, such as resistance training and walking, are known to be effective against chronic low back pain (CLBP). However, few studies have examined the associations of walking and resistance training with CLBP in the general older population. Therefore, this study analyzed these relationships in the older Korean population (aged ≥65 years), with the goal of determining which exercise is better for CLBP.

Is Routine Use of Drain Really Necessary for Posterior Lumbar Interbody Fusion Surgery? A Retrospective Case Series with a Historical Control Group.

Study Design: A retrospective case-control study.

Objectives: The usefulness of a drain in spinal surgery has always been controversial. The purposes of this study were to determine the incidence of hematoma-related complications after posterior lumbar interbody fusion (PLIF) without a drain and to evaluate its usefulness.

A Sulfur-Infused Separator for Boosting Areal Capacity of Li-S Batteries.

This study presents a new approach for enabling the development of high-performance lithium-sulfur (Li-S) cells by simply inserting a sulfur-infused separator (SIS) between a common S cathode and a Li metal anode. All solid sulfur electrically isolated from the cathode is electrochemically reduced to polysulfides during the first discharge. Notably, scanning electron microscopy with energy dispersive X-ray spectroscopy (SEM-EDS) studies have demonstrated that the S in the separator disappears completely even when the cell is discharged to 2.

Tristetraprolin posttranscriptionally downregulates PFKFB3 in cancer cells.

The enzyme 6-phosphofructo-2-kinase/fructose-2,6-bisphosphatases 3 (PFKFB3) catalyzes the first committed rate-limiting step of glycolysis and is upregulated in cancer cells. The mechanism of PFKFB3 expression upregulation in cancer cells has not been fully elucidated. The PFKFB3 3'-UTR is reported to contain AU-rich elements (AREs) that are important for regulating PFKFB3 mRNA stability.

Simultaneous analysis by Quadrupole-Orbitrap mass spectrometry and UHPLC-MS/MS for the determination of sedative-hypnotics and sleep inducers in adulterated products.

Adulterated products are continuously detected in society and cause problems. In this study, we developed and validated a method for determining synthetic sedative-hypnotics and sleep inducers, including barbital, benzodiazepam, zolpidem, and first-generation antihistamines, in adulterated products using Quadrupole-Orbitrap mass spectrometry and ultrahigh performance liquid chromatography with tandem mass spectrometry. In Quadrupole-Orbitrap mass spectrometry analysis, target compounds were confirmed using a combination of retention time, mass tolerance, mass accuracy, and fragment ions.

A LiDAR and IMU Integrated Indoor Navigation System for UAVs and Its Application in Real-Time Pipeline Classification.

Mapping the environment of a vehicle and localizing a vehicle within that unknown environment are complex issues. Although many approaches based on various types of sensory inputs and computational concepts have been successfully utilized for ground robot localization, there is difficulty in localizing an unmanned aerial vehicle (UAV) due to variation in altitude and motion dynamics. This paper proposes a robust and efficient indoor mapping and localization solution for a UAV integrated with low-cost Light Detection and Ranging (LiDAR) and Inertial Measurement Unit (IMU) sensors.

Investigating the real-world emission characteristics of light-duty gasoline vehicles and their relationship to local socioeconomic conditions in three communities in Los Angeles, California.

Unlabelled: This paper discusses results from a vehicular emissions research study of over 350 vehicles conducted in three communities in Los Angeles, CA, in 2010 using vehicle chase measurements. The study explores the real-world emission behavior of light-duty gasoline vehicles, characterizes real-world super-emitters in the different regions, and investigates the relationship of on-road vehicle emissions with the socioeconomic status (SES) of the region. The study found that in comparison to a 2007 earlier study in a neighboring community, vehicle emissions for all measured pollutants had experienced a significant reduction over the years, with oxides of nitrogen (NOX) and black carbon (BC) emissions showing the largest reductions.

The Role of Magnesium Ion Substituted Biphasic Calcium Phosphate Spherical Micro-Scaffolds in Osteogenic Differentiation of Human Adipose Tissue-Derived Mesenchymal Stem Cells.

This study was investigated the role of magnesium (Mg2+) ion substituted biphasic calcium phosphate (Mg-BCP) spherical micro-scaffolds in osteogenic differentiation of human adipose tissue-derived mesenchymal stem cells (hAT-MSCs). Mg-BCP micro-scaffolds with spherical morphology were successfully prepared using in situ co-precipitation and spray drying atomization process. The in vitro cell proliferation and differentiation of hAT-MSCs were determined up to day 14.

pH-Responsive assembly of metal nanoparticles and fluorescent dyes by diblock copolymer micelles.

Hybrid assemblies consisting of metal nanoparticles (NPs) and fluorophores are quite interesting because the intrinsic properties of fluorophores can be engineered in the assembled structure. In this regard, we utilized the self-segregation properties of block copolymer micelles to organize metal NPs and fluorophores simultaneously in a specific arrangement. From the viewpoint of assembly methods, we first encapsulated Au NPs in the PS cores of polystyrene-block-poly(acrylic acid) (PS-PAA) micelles.

Verifying emission reductions from heavy-duty diesel trucks operating on Southern California freeways.

Measurements on truck-dominated freeways in southern California have offered a unique opportunity to track emission changes that have occurred due to the implementation of local and state regulations affecting heavy-duty diesel trucks. These regulations have accelerated fleet turnover to cleaner and newer trucks. In this study, a mobile platform was used to measure nitrogen oxides (NOX), black carbon (BC), and ultrafine particles (UFPs) on diesel-dominated southern California freeways.

A rare case of transformation of childhood myelodysplastic syndrome to acute lymphoblastic leukemia.

Transformation of MDS into ALL during childhood is extremely rare. We report a rare case of an 8-yr-old girl who presented with refractory cytopenia of childhood (RCC) that transformed into ALL only 3 months after the diagnosis of childhood MDS. Although no cytogenetic abnormalities were observed in conventional karyotype and FISH analysis, we found several deletions on chromosomes 5q, 12q, 13q, and 22q.

Parasternal mass revealing as a postvaccinal Bacillus Calmette-Guérin (BCG)-elicited sternal osteomyelitis.

Although osteomyelitis is a very rare complication of Bacillus Calmette-Guérin (BCG) vaccination, sternal osteomyelitis as a late complication of BCG vaccination diagnosed by polymerase chain reaction (PCR) in a child is described.We might consider BCG osteomyelitis in the case of osteomyelitis without bacterial isolation within a year after BCG vaccination, the absence of pulmonary foci, and a contact to the patient with tuberculosis.

The effectiveness of tacrolimus and minidose methotrexate in the prevention of acute graft-versus-host disease following allogeneic hematopoietic stem cell transplantation in children: a single-center study in Korea.

Background: Knowledge of the roles of tacrolimus and minidose methotrexate (MTX) in the prevention of acute graft-versus-host disease (aGVHD) in pediatric allogeneic hematopoietic stem cell transplantation (HSCT) is limited. We retrospectively evaluated the engraftment status, incidence of aGVHD and chronic GVHD (cGVHD), and toxicities of tacrolimus and minidose MTX in aGVHD prophylaxis in children undergoing allogeneic HSCT.

Methods: Seventeen children, who underwent allogeneic HSCT and received tacrolimus and minidose MTX as GVHD prophylaxis from March 2003 to February 2011, were reviewed retrospectively.

Current status of pediatric umbilical cord blood transplantation in Korea: a multicenter retrospective analysis of 236 cases.

We report the outcome of 236 pediatric umbilical cord blood transplantations (UCBT) performed in Korea. Given that the sources of the grafts were mostly unrelated donors (n = 226; 95.8%), only the results of unrelated UCBT were included for all statistics.

A paradoxical reaction during antituberculosis therapy for congenital tuberculosis.

A paradoxical tuberculosis (TB) reaction is defined as the clinical or radiological worsening of pre-existing TB lesions or the development of new lesions during treatment. We treated a case of such a paradoxical reaction in a 21-day-old female infant who was diagnosed with congenital TB and was being treated with antituberculous drugs. The paradoxical reaction improved after additional treatment with corticosteroids.
