The aim of this study is to investigate the effects of crown closure seasonal changes in broad-leaved forests on the thermal comfort and the human responses. The participants were a total of 146 male and female university students. The participants sat in a chair and rested in forests with a high and low crown closure, and then closed their eyes and rested for 5 min.

In this study, the anti-inflammatory effect of the hot water extract of Endarachne binghamiae (EB-WE), a type of marine brown algae, was investigated in LPS-stimulated RAW 264.7 cells and an acute lung injury (ALI) mouse model induced by intranasal LPS administration. Treatment with EB-WE significantly inhibited NO and pro-inflammatory cytokine (TNF-a and IL-6) production in LPS-stimulated RAW 264.

: Aortic dissection (AD) and aortic intramural hematoma (IMH) are fatal diseases with similar clinical characteristics. Immediate computed tomography (CT) with a contrast medium is required to confirm the presence of AD or IMH. This retrospective study aimed to use CT images to differentiate AD and IMH from normal aorta (NA) using a deep learning algorithm.

Article Synopsis
  • The study looked at how the endorsement of modified 2-tiered testing for Lyme disease affected case definitions in North Carolina from 2017 to 2023.
  • After implementing this testing method, confirmed Lyme disease cases rose by 117%, showing a significant increase in reported cases.
  • Conversely, there was a decrease in the number of probable cases, suggesting a shift in how cases are classified since the testing change.

Background/objectives: There are scant established data on the cause, distribution, treatment options, and recurrence rate of pediatric keloids in Asian populations. We characterized clinical features by comprehensively categorizing pediatric keloid patients into prepubertal and postpubertal groups at a single tertiary center.

Methods: We searched the database of Kangbuk Samsung Hospital for pediatric patients (< 18 years) with clinically proven keloids who underwent outpatient-based treatment from 2007 to 2021.

Metal halide perovskite semiconductors have emerged as highly efficient amplifying materials; to ensure practical applicability, it is important to have precise control over the spectral and polarization characteristics of lasing emission. In this study, we present effective strategies for manipulating single- and multimode lasing from surface-emitting and optically pumped perovskite distributed feedback lasers. We show that cladding structures can be made to modify the optical properties of guided transverse electric and magnetic modes within the gain medium.

This study aimed to investigate the effects of prolonged inhalation of nature-derived odors indoors on humans. Twenty-six women participated in this study. Heart rate variability, heart rate, blood pressure, pulse rate, estradiol, testosterone, and cortisol were used as indicators of autonomic nervous system and endocrine system activities.

A building block containing eight zincs and eight iodo groups (8 Zn) is obtained by the Zn complexation of a salen ligand bearing two additional hydroxy groups. Through the Sonogashira-Hagihara coupling of 8 Zn with 1,3,5,7-tetra(4-ethynylphenyl) adamantane, microporous organic polymers bearing octanuclear zinc clusters (MOP-8 Zn) are prepared, exhibiting a high surface area of 562 m g, microporosity, and a particulate morphology with an average diameter of 249 nm. The MOP-8 Zn exhibits significantly enhanced catalytic performance, compared to molecular counterparts, in the reductive carbon dioxide fixation to formamides, possibly due to the cooperative adsorption and confinement effect of networks on substrates.

Lyme disease, caused by infection with Borrelia burgdorferi, is the most common vector-borne disease in the United States. The standard two-tier testing (STTT) algorithm suffers from low sensitivity, misinterpretation, and long turnaround time, preventing timely detection and treatment. To address these challenges, we hypothesized that the canine point-of-care (PoC) SNAP 4Dx Plus test used to detect Borrelia burgdorferi antibodies could be employed for human diagnosis.

A pH-sensitive dye-based freshness indicator has been developed to monitor the quality status of pork neck through distinct color transitions, addressing a crucial need for improved food safety and real-time monitoring within the food industry. This system aims to boost consumer confidence and improve shelf-life estimates by offering transparent and immediate quality indicators. Aerobically packaged pork neck samples underwent accelerated testing at 25 °C for 36 h, followed by refrigeration experiments at typical distribution temperatures of 4 and 8 °C over 10 days.

In this study, we prepared fermented products of isoflavone-enriched soybean leaves (IESLs) and analyzed their nutrients, isoflavones, anti-obesity efficacy, and effects on gut microbiota. Fermented IESLs (FIESLs) were found to be rich in nutrients, especially lauric acid, oleic acid, and linoleic acid. In addition, the concentrations of most essential free amino acids were increased compared to those of IESLs.

Article Synopsis
  • This study investigated how to effectively remove fluoride from semiconductor wastewater and recover it as calcium fluoride using fluidized bed crystallization, achieving over 90% fluoride removal in continuous operation.
  • The particle size and seed bed height significantly increased during the process, and the resulting calcium fluoride crystals were found to have a purity of 91.1%.
  • The study also compared different methods for optimizing fluoride removal, concluding that a two-stage approach was more effective, attaining a fluoride removal rate of 94% under specific operational conditions.

Lithium metal anode (LMA) emerges as a promising candidate for lithium (Li)-based battery chemistries with high-energy-density. However, inhomogeneous charge distribution from the unbalanced ion/electron transport causes dendritic Li deposition, leading to "dead Li" and parasitic reactions, particularly at high Li utilization ratios (low negative/positive ratios in full cells). Herein, an innovative LMA structural model deploying a hyperporous/hybrid conductive architecture is proposed on single-walled carbon nanotube film (HCA/C), fabricated through a nonsolvent induced phase separation process.

This study utilized a fluidized bed reactor (FBR) for fluoride removal from high-concentration fluoride-ion-containing simulated semiconductor industry wastewater and recovered high-purity CaF crystals. The effects of hydraulic retention time (HRT), pH, Ca to F ratio, upflow velocity, seed size and seed bed height were investigated by performing lab-scale batch experiments. Considering fluoride removal and CaF crystallization efficiency, 5 h HRT, pH 6, seed height of 50 cm and [Ca]/[F] ratio of 0.

Introduction: Erosive pustular dermatosis of the scalp (EPDS) is a rare and recalcitrant condition in which chronic scalp pustules and erosive patches are diagnosed by nondiagnostic laboratory tests and histopathological tests. Although various precipitating factors including trauma have been reported, erosive pustular dermatosis arising on the long-standing burn scars is rare.

Case Presentation: We report three cases of EPDS arising on long-standing burn scars.

  • * A 59-year-old woman developed noticeable raised skin bumps on her face after undergoing 16 sessions of 308-nm excimer laser treatment for vitiligo, with the lesions appearing in the areas that had been treated.
  • * The patient's skin samples showed enlarged sebaceous glands, supporting existing research that chronic sun exposure can lead to SH, highlighting a potential side effect of excimer laser therapy in vulnerable individuals.

Extramammary Paget disease (EMPD) is a rare adenocarcinoma that usually occurs in areas of the body that are rich in apocrine sweat glands. Great depth of tumor invasion is a well-known risk factor for worse prognosis. Paget cells usually are limited to the epidermis, whereas invasive EMPD, which infiltrates the dermis, is relatively rare.

Fixed drug eruption (FDE) is a well-defined hyperpigmented patch that recurs in a fixed location each time a particular drug is taken. Common causative agents of FDE are non-steroidal anti-inflammatory drugs, non-narcotic analgesics, sedatives, anticonvulsants, sulfonamides, and tetracycline. We report a 33-year-old male who presented with a recurrent, localized, brownish-to-erythematous macule and papules on the peri-philtrum area two hours after taking valacyclovir.
