Impact of Persistent Alopecia on Quality of Life in Childhood Cancer and Transplant Survivors.

Background: While alopecia associated with chemotherapy, radiation, or hematopoietic stem-cell transplant (C/R/HSCT) is transient in most children, prior reports indicate nearly one in seven childhood cancer survivors suffer from persistent alopecia after their treatment is completed. The objective of our study was to better characterize the impact of C/R/HSCT-associated persistent alopecia on patient quality of life.

Procedure: A cross-sectional cohort study of patients with a history of C/R/HSCT who were seen at Dana Farber Cancer Institute/Boston Children's Hospital Dermatology from August 2023 to February 2024 for any indication was conducted.

Urticaria in infants: A single-institution retrospective study.

Urticaria in infants can cause significant anxiety in parents, especially if a trigger cannot be identified. In a retrospective study of 246 infants seen for urticaria of unknown etiology at Boston Children's Hospital, 88.2% had resolution of urticaria within 6 weeks.

Identification of Terpene Compositions in the Leaves and Inflorescences of Hybrid Species Using Headspace-Gas Chromatography/Mass Spectrometry.

Although cannabidiol and tetrahydrocannabinol in species exert their pharmacological effects via the endocannabinoid system, it is believed that other phytochemicals, particularly terpenes, can modulate therapeutic outcomes through the entourage effect. Therefore, to gain a better understanding of the pharmacological effects of , obtaining information on phytochemical compositions, including mono-, di-, and sesqui-terpenes in species is essential. Applying a sophisticated analytical method is indispensable.

Arctic Sea Ice Microalga KNF0041: Identification and Statistical Optimization of Medium for Enhanced Biomass and Omega-3/Omega-6.

Polar microorganisms produce biologically active compounds that enable them to survive in harsh environments. These compounds have potential biomedical applications. The green microalga KNF0041, isolated from Arctic sea ice, has been found to produce polyunsaturated fatty acids (PUFAs), including omega-3 and omega-6, which have antioxidant properties.

Polar microalgae extracts protect human HaCaT keratinocytes from damaging stimuli and ameliorate psoriatic skin inflammation in mice.

Background: Polar microalgae contain unique compounds that enable them to adapt to extreme environments. As the skin barrier is our first line of defense against external threats, polar microalgae extracts may possess restorative properties for damaged skin, but the potential of microalgae extracts as skin protective agents remains unknown.

Purpose: This study aimed to analyze compound profiles from polar microalgae extracts, evaluate their potential as skin epithelial protective agents, and examine the underlying mechanisms.

Flow Characteristics of the Conjugate of Anti-CD3 Monoclonal Antibodies and Magnetic Nanoparticle in PBS and Blood Vessels.

Previously, anti-CD3 antibodies delivered intravenously have been known for their negative side effects. The experimental conditions for optimal liquid production are derived from the Fc-directed conjugation of anti-CD3 foralumab antibodies and magnetic nanoparticles (Ab-MNPs). The anti-CD3 antibodies are prepared for conjugation with MNPs using SiteClick antibody labelling kits.

Antarctic Marine Algae Extracts as a Potential Natural Resource to Protect Epithelial Barrier Integrity.

The intestine and skin provide crucial protection against the external environment. Strengthening the epithelial barrier function of these organs is critical for maintaining homeostasis against inflammatory stimuli. Recent studies suggest that polar marine algae are a promising bioactive resource because of their adaptation to extreme environments.

Freezing-enhanced oxidation of iodide by hydrogen peroxide in the presence of antifreeze proteins from the Arctic yeast Leucosporidium sp.AY30.

Ice-binding proteins (IBPs), originating from Arctic or Antarctic microorganisms, have freeze-inhibiting characteristics, allowing these organisms to survive in polar regions. Despite their significance in polar environments, the mechanism through which IBPs affect the chemical reactions in ice by controlling ice crystal formation has not yet been reported. In this study, a new mechanism for iodide (I) activation into triiodide (I), which is the abundant iodine species in seawater, by using hydrogen peroxide (HO) in a frozen solution with IBPs was developed.

Importance of rigidity of ice-binding protein (FfIBP) for hyperthermal hysteresis activity and microbial survival.

Ice-binding proteins (IBPs) are well-characterized proteins responsible for the cold-adaptation mechanisms. Despite extensive structural and biological investigation of IBPs and antifreeze proteins, only a few studies have considered the relationship between protein stabilization and thermal hysteresis (TH) activity as well as the implication of hyperactivity. Here, we investigated the important role of the head capping region in stabilization and the hyper-TH activity of FfIBP using molecular dynamics simulation.

Association between thyroid hormone and components of metabolic syndrome in euthyroid Korean adults: A population-based study.

Thyroid dysfunction increases the prevalence of metabolic syndrome. However, the link between thyroid hormones and metabolic syndrome remains debatable, and the effect of sex on their relationship is not completely understood. To elucidate the relationship of thyroid hormones with metabolic syndrome and its components according to sex in euthyroid individuals in South Korea.

Bacterially Delivered miRNA-Mediated Toll-like Receptor 8 Gene Silencing for Combined Therapy in a Murine Model of Atopic Dermatitis: Therapeutic Effect of miRTLR8 in AD.

In atopic dermatitis (AD), skin inflammation is caused by complex interactions between genetic disposition and aberrant innate/adaptive immune responses. Toll-like receptors (TLRs) are key molecules in the innate/adaptive immune response as they recognize various molecular motifs associated with pathogens. Among them, TLR8 is implicated in eczematous skin reactions.

Continuing patient care to underserved communities and medical education during the COVID-19 pandemic through a teledermatology student-run clinic.

A virtual pediatric dermatology student-run clinic was initiated during the COVID-19 pandemic, when in-person educational opportunities were limited. The clinic's aim is to provide high-quality dermatologic care to a diverse, underserved pediatric patient population while teaching trainees how to diagnose and manage common skin conditions. In our initial eight sessions, we served 37 patients, predominantly those with skin of color, and had a low no-show rate of 9.

Mitochondrial genome of the Antarctic microalga KSF0127 (Chlorellaceae, Trebouxiophyceae).

We report the first mitochondrial genome of the Antarctic microalga KSF0127. The circular mitochondrial genome was 67,923 bp in length and contained 45 protein-coding genes, one ribosomal RNA gene, and 60 transfer RNA genes. The phylogenetic tree was constructed with eight previously reported mitogenome sequences and showed the phylogenetic position of KSF0127 within the Chlorellaceae family.

Co-production of biodiesel and bioethanol using psychrophilic microalga sp. KNM0029C isolated from Arctic sea ice.

Background: Biofuels, generated using microalgae as sustainable energy, have received a lot of attention. Microalgae can be cultivated at low cost with CO and solar energy without competition from edible crops. Psychrophilic microalgae can be a suitable feedstock to produce biofuels without the environmental constraints of low temperatures, because they can grow below 10 °C.
