Cordyceps militaris (L.) Link (C. militaris) contains various beneficial substances, including polysaccharides (galactomannan), nucleotides (adenosine and cordycepin), cordycepic acid, amino acids, and sterols (ergosterol and beta-sitosterol). It also contains other essential nutrients, such as protein, vitamins (E, K, B1, B2, and B12), and minerals (potassium, sodium, calcium, magnesium, iron, zinc, and selenium). Due to the numerous health benefits of supplements and products containing C. militaris extract, their popularity has increased...

The growth of the Urban Air Mobility (UAM) industry emphasizes the need for considerable study into assembly procedures and dependability to guarantee its effective integration into air transport networks. In this context, this study seeks to evaluate the mechanical characteristics of bolted joint Carbon Fiber Reinforced Plastic (CFRP), with a particular emphasis on bearing strength. By altering the w/D (specimen width to hole diameter) and e/D (distance between hole center and specimen end to hole diameter) ratios, the study investigates how edge and end distances affect material performance...

Compared to terrestrial transportation systems, the expansion of urban traffic into airspace can not only mitigate traffic congestion, but also foster establish eco-friendly transportation networks. Additionally, unmanned aerial vehicle (UAV) task allocation and trajectory planning are essential research topics for an Urban Air Mobility (UAM) scenario. However, heterogeneous tasks, temporary flight restriction zones, physical buildings, and environment prerequisites put forward challenges for the research. In this paper, multigene and improved anti-collision RRT* (IAC-RRT*) algorithms are proposed to address the challenge of task allocation and path planning problems in UAM scenarios by tailoring the chance of crossover and mutation...

BACKGROUND: Practitioners who support unaccompanied minors (UAMs) come from different professional backgrounds and often are not appropriately trained to address children's complex mental health needs. This gap informed a training programme across all accommodation centres in Greece. METHODS: The aim of the Train-of-Trainer (ToT) national programme was to upskill trainers from 17 organisations to cascade knowledge. Training was interprofessional, trauma-informed and culturally sensitive...

Chaperone-mediated autophagy (CMA) is a lysosome-dependent degradation pathway that eliminates proteins that are damaged, partially unfolded, or targeted for selective proteome remodeling. CMA contributes to several cellular processes, including stress response and proteostasis. Age-associated increase in cellular stressors and decrease in CMA contribute to pathologies associated with aging in various tissues. CMA contributes to bone homeostasis in young mice. An age-associated reduction in CMA was reported in osteoblast lineage cells; however, whether declining CMA contributes to skeletal aging is unknown...

This paper introduces a new decentralized control strategy for an unmanned aerial manipulator (UAM) constrained to the vertical plane. The control strategy comprises two loops: the first compensates for the aerial vehicle's impact on the manipulator; and the second one implements independent controllers for the aerial vehicle and the manipulator. The controller for the aerial vehicle includes an estimator to compensate for the dynamic influence of the manipulator, even if it is affected by external wind-gust disturbances...

We previously demonstrated that mutation of sarA in Staphylococcus aureus limits biofilm formation, cytotoxicity for osteoblasts and osteoclasts, and virulence in osteomyelitis, and that all of these phenotypes can be attributed to the increased production of extracellular proteases. Here we extend these studies to assess the individual importance of these proteases alone and in combination with each other using the methicillin-resistant USA300 strain LAC, the methicillin-susceptible USA200 strain UAMS-1, and isogenic sarA mutants that were also unable to produce aureolysin (Aur), staphopain A (ScpA), staphylococcal serine protease A (subsp...

The study aimed to optimize the ultrasonic-assisted modification (UAM) of corn and potato starch by assessing the influence of ultrasound geometry, power, and frequency on the fluid flow for sonicated starch to achieve porous starch with a higher degree of hydrolyzing by α-amylase. This assessment was conducted through mathematical modeling and 3D computational fluid dynamics (CFD) simulations. The ultrasonic pressure field is determined by the solution of the non-linear Westervelt equation in the frequency domain...

BACKGROUND: The decline in nuclear medicine (NM) residencies in the United States has led to a shortage of NM physicians. To help address this, a 16-month NM pathway for diagnostic radiology (DR) residents was developed in 2010. At the University of Arkansas for Medical Sciences, we matched our first resident into the NuRad (NM + DR) pathway in 2013. Despite our success, we remain one of only five programs in the United States that offers a combined training pathway through the National Resident Matching Program...

A deep learning based method is proposed to predict the urban air mobility (UAM) noise propagation in the urban environment. This method aims to efficiently estimate the noise impact of UAM flights on the complex urban area. The noise hemisphere was created via the comprehensive multirotor noise assessment framework to determine the noise level of UAM. The noise propagation to a randomly generated three-dimensional (3D) urban area was then calculated using the ray tracing method, including atmospheric attenuation and multiple reflections...

OBJECTIVE: Conduct a multisite, survey-based study assessing rates of self-reported depressive symptoms among student pharmacists enrolled in the first 3 years (P1-P3) of 4-year Doctor of Pharmacy (PharmD) curricula. METHODS: This study followed a cross-sectional observational design conducted at Washington State University, College of Pharmacy and Pharmaceutical Sciences, and the University of Arkansas for Medical Sciences, College of Pharmacy. Student pharmacists in the first 3 years of pharmacy school (P1-P3) of the PharmD curricula were invited to voluntarily complete the Center for Epidemiologic Studies Depression Scale (CES-D) to collect self-reported measures of depression...

In the rapidly evolving urban advanced mobility (UAM) sphere, Vehicular Ad Hoc Networks (VANETs) are crucial for robust communication and operational efficiency in future urban environments. This paper quantifies VANETs to improve their reliability and availability, essential for integrating UAM into urban infrastructures. It proposes a novel Stochastic Petri Nets (SPN) method for evaluating VANET-based Vehicle Communication and Control (VCC) architectures, crucial given the dynamic demands of UAM. The SPN model, incorporating virtual machine (VM) migration and Edge Computing, addresses VANET integration challenges with Edge Computing...

This study investigates the acquisition of anaphora resolution (AR) in Spanish as a second language (L2). According to the Position of Antecedent Strategy (PAS), in native Spanish null pronominal subjects are biased toward subject antecedents, whereas overt pronominal subjects show a "flexible" bias (typically toward non-subject but also toward subject antecedents). The PAS has been extensively investigated in experimental studies, though little is known about real production. We show how naturalistic production (corpus methods) can uncover crucial factors in the PAS that have not been explored in the experimental literature...

Nanoconfinement in metal-organic framework (MOF) pores can lead to the isolation of unusual or reactive metal complexes. However, MOFs that support the stabilization and precise structural elucidation of metal complexes and small metal clusters are rare. Here, we report a thermally and chemically stable zirconium-based MOF (University of Adelaide Material-1001, UAM-1001) with a high density of free bis-pyrazolyl units that can confine mono- and dinuclear metal complexes. The precursor MOF, UAM-1000, has a high degree of structural flexibility, but post synthetic modification with a bracing linker, biphenyl-4,4'-dicarboxylic acid, partially rigidifies the MOF (UAM-1001)...

STUDY DESIGN: Retrospective radiographic study. PURPOSE: This study aims to demonstrate the proper resection trajectory of a partial posterior uncinate process resection combined with anterior cervical discectomy and fusion (ACDF) and evaluate whether foraminal stenosis or uncinate process degeneration increases the risk of vertebral artery (VA) injury. OVERVIEW OF LITERATURE: Appropriate resection trajectory that could result in sufficient decompression and avoid vertebral artery injury is yet unknown...

BACKGROUND: Azithromycin (AZM) is a macrolide antibiotic that exhibits anti-inflammatory and anti-viral infection properties by enhancing type-I interferon (IFN-I) responses. The stimulator of interferon genes (STING) can directly induce IFN-I production. However, elevated IFN-I induces auto-immune phenotypes such as systemic lupus erythematosus (SLE). The effects of AZM and STING on the production of IFN-I are unclear. OBJECTIVE: Therefore, this study aims to evaluate the role of AZM and STING on IFN-I responses in macrophages...

Listeria monocytogenes is a facultative intracellular foodborne pathogen and the causative agent of the severe disease listeriosis. It is found ubiquitously in the environment and exhibits innate resistance to certain antimicrobials, but acquired antimicrobial resistance remains relatively uncommon. Given the potentially dire health outcomes associated with listeriosis, acquisition of antimicrobial resistance (AMR) by this pathogen is of considerable public health concern. AMR in L. monocytogenes has been surveyed frequently in strains of clinical and food origin, but much less commonly in wildlife...

This study aims to evaluate whether the perennial grass water extract ( Pogonatherum panicum ) ameliorate mitochondrial DNA (mtDNA) leakage. MATERIALS/METHODS: The major bioactive constituents of P. paniceum (PPW) were investigated by high-performance liquid chromatography, after which their antioxidant activities were assessed. In addition, RAW 264.7 macrophages were stimulated with lipopolysaccharide, resulting in mitochondrial damage...

This study aimed to develop a longitudinal ultrasonic-assisted milling system to investigate the machinability of titanium (Ti) Alloy Ti-6Al-4V (TC4). Aiming at reduced milling force and enhanced surface quality, ultrasonic-assisted milling was investigated taking into account the following processing parameters: spindle speed (cutting rate) n , feed per tooth f z , milling depth a p , and ultrasonic amplitude A . A comparison was made with conventional milling. The results of univariate tests demonstrated that the ultrasonic amplitude had the most significant impact on the milling force along the z -axis, resulting in a reduction of 15...

R2-ISS was published in 2022 and has been validated in several cohorts of myeloma patients. In this study, we investigated a total of 1007 multiple myeloma (MM) patients who received autologous stem cell transplantation (ASCT) between 2001 and 2021. The median age of the patients was 61 years, with a median overall survival (OS) of 91 months and median progression-free survival (PFS) of 66 months. We collected the variables included in the R-ISS and R2-ISS system, as well as additional data such as routine blood markers, bone marrow plasmacytosis, and selected metabolic variables including serum glucose and cholesterol levels...
