Developmental morphology of claspers and clasper‐glands during maturation in Potamotrygon wallacei (Chondrichthyes: Potamotrygoninae)

The Anatomical Record, EarlyView.
Abstract The claspers are the copulatory organs in male elasmobranchs, responsible for directing the semen into the female cloaca (C). However, the microscopic morphology of the claspers remains poorly understood. This study describes the morphology of the claspers and clasper glands (CGs) of cururu stingray (Potamotrygon wallacei) at different ...

Revealing Structure–Performance Relations in Core‐Shell Catalyst‐Based PEM Water Electrolyzer Anodes with Low Iridium Loading

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Table of Contents The TiO2@IrO2 core–shell architecture ensures high electronic conductivity even at a low iridium content of 10 wt%. The resulting catalyst layer shows significantly higher iridium utilization than a commercial reference, leading to improved PEMWE single‐cell performance at low iridium loading.

Ultrasound velocity profile (UVP) measurements in shallow open-channel flows [PDF]

, 2010
This paper is concerned with velocity measurements in shallow water flows by using Ultrasonic Velocity Profile (UVP) probes. The measurements were made in a 10 m long, 0.4 m wide flume whose slope is 0.00117.

Toll‐Like Receptors in the Mechanism of Hexabromocyclododecane‐Induced Production of Pro‐Inflammatory Cytokines

Journal of Applied Toxicology, EarlyView.
ABSTRACT Hexabromocyclododecane (HBCD), a brominated flame retardant, has raised increasing health concerns due to its bioaccumulation in human tissues and its ability to induce proinflammatory cytokines. Interleukin‐1β (IL‐1β), interleukin‐6 (IL‐6), and tumor necrosis factor‐α (TNF‐α) are major mediators of inflammation, and their chronic elevation ...

Development and Characterization of Liposomes Containing a Zn(II) Porphyrin Derivative for the Application of Photodynamic Therapy in the Treatment of Breast Cancer

Lasers in Surgery and Medicine, EarlyView.
ABSTRACT Objectives This study aims to synthesize and characterize lipid nanosystems (liposomes) for the incorporation of a Zn(II) porphyrin derivative, Zn(II) meso‐tetrakis(N‐n‐hexylpyridinium‐2‐yl)porphyrin (ZnTnHex‐2‐PyP4+, ZnPH), intending to employ an alternative method of treatment, such as photodynamic therapy (PDT), for breast cancer (BC ...

Hydrogen Bonding Denticity Governs Surface Modulation in Inorganic Perovskite Nanocrystals

Small, EarlyView.
Organic cations with distinct hydrogen‐bonding denticities enable systematic modulation of perovskite nanocrystal surfaces. Increasing denticity from mono‐dentate MA+ to bi‐dentate FA+ and multi‐dentate GA+ strengthens interactions with surface iodides, effectively suppressing surface defects.
