Kinetics of reformation of the S state capable of progressing to the S state after the O release by photosystem II.

Photosynth Res

January 2025

Department of Chemistry, Graduate School of Science and Technology, Proteo-Science Research Center, Ehime University, Bunkyo-cho, Matsuyama, Ehime, 790-8577, Japan.

The active site for water oxidation in photosystem II (PSII) comprises a MnCaO cluster adjacent to a redox-active tyrosine residue (Tyr). During the water-splitting process, the enzyme transitions through five sequential oxidation states (S to S), with O evolution occurring during the STyr· to STyr transition. Chloride also plays a role in this mechanism.

A vibrational circular dichroism (VCD) instrument having a thermoelectrically cooled detector (denoted as a TEC unit) was constructed in this study. An electronic device, instead of liquid nitrogen, was employed in the instrument to cool the detector. The feasibility of the system was examined by recording the VCD spectra of liquid pinenes and insect wings.

Unlabelled: The immune system plays a central role in controlling acute hepatitis B infection and in patients resolving chronic hepatitis B (CHB). Given that 221 million (75%) of CHB patients reside in low- and middle-income countries, the development of a vaccine with therapeutic properties represents a rational and cost-effective approach more than a romantic endeavor. This review systematically analyzes the key variables related to the safety, efficacy, and effectiveness of CHB treatments.

December 2024

Department of General Thoracic Surgery and Breast and Endocrinological Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama, Japan.

Background: Lung cancer with interstitial pneumonia is known to be a refractory disease. We explored whether systemic inflammatory response markers are associated with outcomes in these patients.

Methods: The participants of this multicenter retrospective study, consisting of 17 medical institutions, were treatment-naïve patients with lung cancer combined with interstitial pneumonia who underwent surgical resection between 2012 and 2017.

Introduction: Leptomeningeal disease (LMD) in diffuse midline gliomas (DMGs) can lead to devastating symptoms such as severe pain, urinary incontinence, and tetraparesis, with limited treatment options. We determined whether detecting H3F3A K27M-mutant droplets in cerebrospinal fluid (CSF) circulating tumor deoxyribonucleic acid (ctDNA) could be a biomarker for detecting LMD in DMGs.

Methods: Twenty-five CSF samples were obtained from 22 DMG patients.

Background: There is limited evidence on the association between maternal anemia during pregnancy and the risk of childhood allergic disorders, with regards to atopic eczema. The current pre-birth cohort study aimed to examine the association between maternal anemia during pregnancy and the risk of atopic eczema in Japanese 2-year-olds.

Methods: The study included 1354 Japanese mother-child pairs.

Objective: This study aimed to elucidate the relationship between daily eating habits and stroke risk factors in O City, Ehime Prefecture, Japan, using stroke registry data collected over a 26-year follow-up period based on standardized national criteria.

Materials And Methods: Overall, 1,793 middle-aged Japanese participants (446 men and 1,347 women) who completed a 33-item Food Frequency Questionnaire (FFQ) and had no history of stroke were matched to those from O City in a stroke registry from 1996 to 2022. Stroke diagnosis for each person was used to determine whether this was their first documented stroke, and we classified strokes as either a cerebral infarction (CI) or a hemorrhagic stroke (HS), the latter which included an intracerebral hemorrhage (ICH) or a subarachnoid hemorrhage (SAH).

Purpose: Corynebacterium species are commensals of human skin and mucous membranes and are recognized as important pathogens in ocular infections. This study investigated the clinical characteristics of Corynebacterium keratitis.

Methods: We retrospectively reviewed cases of bacterial keratitis in which Corynebacterium species were solely isolated from corneal scraping cultures collected at Ehime University Hospital between January 2010 and February 2024.

Article Synopsis
  • The study emphasizes the significance of nickel, copper, and selenium as essential biometals in various industries, but highlights their harmful impact as environmental pollutants when they exceed normal levels, particularly in aquatic ecosystems.
  • Research on medaka fish embryos revealed that exposure to these biometals led to significant developmental abnormalities and increased mortality rates throughout a 14-day observation period.
  • Gene expression analysis showed that copper was the most toxic, affecting over 4,700 genes, while all three biometals caused detrimental effects on fish embryo development, underscoring the necessity of monitoring biometal levels to protect aquatic life.

This study investigated the association between green tea or coffee consumption with cerebral white matter lesions and hippocampal and total brain volumes among 8766 community-dwelling participants recruited from the Japan Prospective Studies Collaboration for Aging and Dementia between 2016 and 2018. A Food Frequency Questionnaire was used to assess green tea and coffee consumption, whereas brain magnetic resonance imaging was performed to assess cerebral white matter lesions, hippocampal volume, and total brain volume. Multivariable-adjusted analysis revealed significant correlations between fewer cerebral white matter lesions and higher green tea consumption, whereas no significant differences were found between green tea consumption and hippocampal or total brain volume.

Endothelial-secreted Endocan activates PDGFRA and regulates vascularity and spatial phenotype in glioblastoma.

Nat Commun

January 2025

The Intellectual and Developmental Disabilities Research Center, The Semel Institute for Neuroscience and Human Behavior, and The Broad Stem Cell Research Center, The Jonsson Comprehensive Cancer Center, David Geffen School of Medicine at UCLA, Los Angeles, CA, USA.

Extensive neovascularization is a hallmark of glioblastoma (GBM). In addition to supplying oxygen and nutrients, vascular endothelial cells provide trophic support to GBM cells via paracrine signaling. Here we report that Endocan (ESM1), an endothelial-secreted proteoglycan, confers enhanced proliferative, migratory, and angiogenic properties to GBM cells and regulates their spatial identity.

Aim: This study aimed to compare the prognostic performance of the risk models for patients with hepatocellular carcinoma (HCC) receiving atezolizumab and bevacizumab (Atez/Bev) as first-line treatment.

Methods: Among 449 patients included in this retrospective multicenter study, we compared the prognostic performance of 13 risk models for the 12-month and 18-month survival status using area under the curve (AUC), net reclassification improvement (NRI), and relative integrated discrimination improvement (IDI) analysis. We also constructed a calibration plot to assess the fitness of each model.

Artificially induced haploidy is lethal in vertebrates, although it is useful for genetic screening and genome editing due to its single set of genomes. Haploid embryonic stem (ES) cell lines in mammals contribute to genetic studies and the production of gametes derived from haploid ES cells. In fish breeding, doubled haploids (DHs) induced by artificially induced gynogenesis are used to generate isogenic gametes for cloning purposes.

Thermal burns of the larynx are uncommon but can lead to serious upper airway obstruction due to edema and bleeding, especially in children who may struggle to communicate their symptoms effectively. This report presents the case of a one-year-and-seven-month-old boy who developed stridor and respiratory distress after eating a heated potato, which ultimately required tracheal intubation. The initial evaluation suggested foreign body aspiration; however, laryngoscopy confirmed significant arytenoid swelling and airway narrowing due to thermal burns.

Article Synopsis
  • The study investigates the link between educational levels and arterial stiffness in Japanese men and women, focusing on data over a five-year period.
  • Among the 1381 participants, results showed no significant difference in baseline arterial stiffness based on education, but older women (≥ 65 years) with higher education had less increase in arterial stiffness over five years.
  • The findings suggest that education may influence arterial stiffness differently based on age and sex, particularly highlighting its impact on older women.
