Correlations between Skin Condition Parameters and Ceramide Profiles in the Stratum Corneum of Healthy Individuals.

Ceramides are essential lipids for skin barrier function, and various classes and species exist in the human stratum corneum (SC). To date, the relationship between skin conditions and ceramide composition in healthy individuals has remained largely unclear. In the present study, we measured six skin condition parameters (capacitance, transepidermal water loss, scaliness, roughness, multilayer exfoliation, and corneocyte cell size) for the SC of the cheeks and upper arms of 26 healthy individuals and performed correlation analyses with their SC ceramide profiles, which we measured via liquid chromatography-tandem mass spectrometry.

White adipose tissue undergoes browning during preweaning period in association with microbiota formation in mice.

Beige adipocytes are transiently induced during early postnatal period in mice. Previous studies have suggested that, unlike in adults, the induction is independent of the sympathetic nerve activity; however, the mechanism is yet unknown. Here, we showed that beige adipocytes are induced during the preweaning period in association with the formation of microbiota in mice.

[Attempt to Calculate the Efficiency of Methylation Using H-NMR for Analyzing Brominated Vegetable Oil].

We studied the efficiency of methylation for analyzing brominated vegetable oil (BVO). In this report, we investigated whether H-NMR is an applicable method for assessing the efficiency of methylation to analyze BVO. H-NMR sufficiently calculated the efficiency of methylation using each integral and the numbers of protons derived from the methyl group, which is characteristic in products, and the methine group, which is characteristic in unreacted substances.

Persistent hyperplastic primary vitreous in two piglets.

Two Large Yorkshire piglets were diagnosed as persistent hyperplastic primary vitreous (PHPV). In case 1, the white cord-like structure extending from optic disc to lens was observed in the normal-sized right eye. Case 2 showed buphthalmos of the right eye.

Monovision by Implantation of Posterior Chamber Phakic Intraocular Lens with a Central Hole (Hole ICL) for Early Presbyopia.

This study was aimed to evaluate visual performance at near to far distances in early presbyopic patients undergoing monovision by implantation of an ICL with a central hole (hole ICL). This pilot study comprised thirty-four eyes of 17 early presbyopic patients (age, 40 to 53 years) who underwent hole ICL implantation, and whose targeted refraction was set at emmetropia for the dominant eye, and at slight myopia (-0.5 to -1.

Arginine vasopressin altered the expression of monocarboxylate transporters in cultured astrocytes isolated from stroke-prone spontaneously hypertensive rats and congenic SHRpch1_18 rats.

Background: Astrocytes support a range of brain functions as well as neuronal survival, but their detailed relationship with stroke-related edema is not well understood. We previously demonstrated that the release of lactate from astrocytes isolated from stroke-prone spontaneously hypertensive rats (SHRSP/Izm) was attenuated under stroke conditions. The supply of lactate to neurons is regulated by astrocytic monocarboxylate transporters (MCTs).

Diagnostic capability of Pulsar perimetry in pre-perimetric and early glaucoma.

This study aimed to compare the diagnostic capability of Pulsar perimetry (Pulsar) in pre-perimetric glaucoma (PPG) and early glaucoma (EG) with that of Flicker perimetry (Flicker) and spectral-domain optical conference tomography (SD-OCT). This prospective cross-sectional study included 25 eyes of 25 PPG patients, 35 eyes of 35 EG patients, and 42 eyes of 42 healthy participants. The diagnostic capability using the area under the curve (AUC) of the best parameter and agreement of detectability between structural and functional measurements were compared.

Diagnostic Ability and Repeatability of a New Supra-Threshold Glaucoma Screening Program in Standard Automated Perimetry.

Purpose: We assess the diagnostic ability and repeatability of a new suprathreshold glaucoma screening test (GST) comprising 28 test points and a 1-of-3 sampling strategy at 95% of the normal limit for standard automated perimetry (SAP) in early to advanced glaucoma.

Methods: This prospective cross-sectional study included 96 eyes of patients with early, moderate, or advanced glaucoma and 37 eyes of normal controls. Participants were evaluated by the G-Dynamic threshold test once and the GST twice, in random order, using the Octopus 600 perimeter.

Comparison of Size Modulation Standard Automated Perimetry and Conventional Standard Automated Perimetry with a 10-2 Test Program in Glaucoma Patients.

Purpose: This prospective observational study compared the performance of size modulation standard automated perimetry with the Octopus 600 10-2 test program, with stimulus size modulation during testing, based on stimulus intensity and conventional standard automated perimetry, with that of the Humphrey 10-2 test program in glaucoma patients.

Methods: Eighty-seven eyes of 87 glaucoma patients underwent size modulation standard automated perimetry with Dynamic strategy and conventional standard automated perimetry using the SITA standard strategy. The main outcome measures were global indices, point-wise threshold, visual defect size and depth, reliability indices, and test duration; these were compared between size modulation standard automated perimetry and conventional standard automated perimetry.

Hypoxia Inducible Factor 1 Alpha Is Expressed in Germ Cells throughout the Murine Life Cycle.

Pluripotent stem cells of the early embryo, and germ line cells, are essential to ensure uncompromised development to adulthood as well as species propagation, respectively. Recently, the transcription factor hypoxia inducible factor 1 alpha (Hif1α) has been shown to have important roles in embryonic stem cells; in particular, regulation of conversion to glycolytic metabolism and, as we have shown, maintenance of functional levels of telomerase. In the present study, we sought to assess whether Hif1α was also expressed in the primitive cells of the murine embryo.

Morphology of P2X3-immunoreactive nerve endings in the rat laryngeal mucosa.

The morphological characteristics of P2X3-immunoreactive nerve endings in the laryngeal mucosa were herein examined using immunohistochemistry with confocal laser microscopy. Ramified intraepithelial nerve endings immunoreactive to P2X3 were distributed in the epiglottis and arytenoid region. The axon terminals of P2X3-immunoreactive ramified endings were beaded or flat in shape.

Investigation Into the Antinfluenza Agent Oseltamivir Distributed via the Internet in Japan.

This study evaluated the quality and authenticity of the anti-influenza agent oseltamivir acquired via the Internet in Japan. The brand name drugs Tamiflu and Antiflu were obtained via the Internet using a search engine. The authenticity and legitimacy of the medicines were verified with the samples' manufacturers and the regulatory authorities of the country of origin, respectively.
