Lysophosphatidylserine (lyso-PS) is a potent hormone-like signaling lysophospholipid, which regulates many facets of mammalian biology and dysregulation in its metabolism is associated with several human neurological and autoimmune diseases. Despite the physiological importance and causal relation with human pathophysiology, little is known about the metabolism of lyso-PS in tissues other than the nervous and immune systems. To address this problem, here, we attempted to identify one (or more) lipase(s) capable of degrading lyso-PS in different mammalian tissues.

Bismuth-based photocatalysts proved to have remarkable photoactivity for antibiotic degradation from water. However, the two significant challenges of bismuth-based photocatalysts are the fast charge recombination rate and higher energy band gap. This study successfully synthesized a novel I-Bi/BiWO/MWCNTs (C-WBI) heterostructure composite photocatalysts with shorter energy band-gap and higher charge production capability through interfacial amidation linkage.

Lysoglycerophospholipid metabolism alterations associated with ambient fine particulate matter exposure: Insights into the pro-atherosclerotic effects.

Environ Pollut

January 2025

SKL-ESPC & SEPKL-AERM, College of Environmental Sciences and Engineering, and Center for Environment and Health, Peking University, Beijing, China. Electronic address:

The biological pathways connecting ambient fine particulate matter (PM)-induced initial adverse effects to the development of atherosclerotic cardiovascular diseases are not fully understood. We hypothesize that lysoglycerophospholipids (LysoGPLs) are pivotal mediators of atherosclerosis induced by exposure to PM. This study investigated the changes of LysoGPLs in response to PM exposure and the mediation role of LysoGPLs in the pro-atherosclerotic effects of PM exposure.

On the correction factors for small field dosimetry in 1.5T MR-linacs.

Phys Med Biol

January 2025

Medical Physics Laboratory, School of Medicine, National and Kapodistrian University of Athens, 75 Mikras Asias, Goudi, Athens, Attica, 11527, GREECE.

Clinical dosimetry in the presence of a 1.5T magnetic field is challenging, let alone in case small fields are involved. The scope of this study is to determine a set of relevant correction factors for a variety of MR-compatible detectors with emphasis on small fields.

Purpose: To describe a case of central retinal artery occlusion following scleral buckling procedure combined with pneumoretinopexy in a patient with sickle cell (HbSC) retinopathy (SCR).

Methods: Scleral buckling procedure, combined with injection of 0.3 ml of 100% perfluoropropane (C3F8) gas in the vitreous, was performed without intra-operative complications under general anaesthesia as treatment of two separate macula-sparing rhegmatogenous retinal detachments secondary to round holes, involving superior and inferior retina respectively, in the right eye of a 26-year-old Afro-Caribbean female with sickle cell disease.

The NASA Mars 2020 Perseverance Rover Mission has collected samples of rock, regolith, and atmosphere within the Noachian-aged Jezero Crater, once the site of a delta-lake system with a high potential for habitability and biosignature preservation. Between sols 109 and 1,088 of the mission, 27 sample tubes have been sealed, including witness tubes. Each sealed sample tube has been collected along with detailed documentation provided by the Perseverance instrument payload, preserving geological and environmental context.

Background: Patient-reported outcomes (PROs) have become indispensable measures in allergic rhinitis (AR) clinical trials. However, there is currently no scale specifically designed for the Chinese population. This study aimed to develop and validate the patient-reported outcome scale for allergic rhinitis (AR-PRO) to provide a reliable tool for AR patients in China.

This study aimed to test the use of Rietveld refinement on respirable aerosol samples to determine the phase of respirable crystalline silica (RCS) and other minerals. The results from the Rietveld refinement were compared to an external standard method and gravimetrical measurements. Laboratory samples consisting of α-quartz, feldspar, and calcite with variable proportions and total mass loadings were made and analyzed using the NIOSH 7500 , followed by Rietveld refinement.

Researching gender and loneliness differently.

Ann N Y Acad Sci

January 2025

Social and Behavioural Sciences, Utrecht University, Utrecht, The Netherlands.

The majority of research on loneliness considers gender by comparing the loneliness reported by men and women. Drawing on current conceptualizations of gender and its effects, we propose alternative ways in which gender should be examined in relation to loneliness. To do so, we consider multiple gender-related factors and the role of the social environment, particularly societal ideologies about what gender is and how it should be expressed.

There is increasing recognition of the need to address the diverse experiences of individuals subjected to medically unnecessary, non-voluntary genital cutting in childhood. This includes children with intersex traits undergoing 'normalisation' surgeries and those with anatomically normative genitalia, such as female genital cutting or male circumcision. While most research on non-therapeutic childhood penile circumcision centres on the physical risks and benefits, far less attention has been given to the potential long-term mental health impacts, particularly from a psychotherapeutic perspective.
