Evaluation of canine epidermis and keratinocytoids (keratinocytic organoids) by transmission electron microscopy. [PDF]

Vet Dermatol
Background – Skin disease is a common complaint in veterinary medicine. Current models often use live animals. Epidermal organoids (keratinocytoids) are 3D miniature organs created in culture from single epidermal keratinocytes. These keratinocytoids can be used as an alternative to live animal studies to investigate epidermal structures and skin ...

Ru(II)‐Cyanine Complexes as Promising Photodynamic Photosensitizers for the Treatment of Hypoxic Tumours with Highly Penetrating 770 nm Near‐Infrared Light

Chemistry – A European Journal, Volume 29, Issue 61, November 2, 2023., 2023
A novel class of Ruthenium(II) complexes that can be photoactivated at 770 nm under hypoxic conditions thanks to the incorporation of a heptamethine cyanine dye is described. Abstract Light‐activated treatments, such as photodynamic therapy (PDT), provide temporal and spatial control over a specific cytotoxic response by exploiting toxicity differences

Rose petal effect: A subtle combination of nano‐scale roughness and chemical variability

Nano Select, Volume 3, Issue 5, Page 977-989, May 2022., 2022
The high contact angle and major drop adhesion of water drops to natural rose petal surfaces is a result of their fractal‐like roughness and nano‐scale chemical heterogeneity as shown here using atomic force microscopy. The combination of topographic and chemical variability is described by a single wetting parameter which can be applied to any sort of

Optical diffraction applied to electron microscopy. A model of diffractometer and image processing unit.

Acta Médica Portuguesa, 1979
The analysis of images obtained in the electron microscope is made mostly through subjective mechanisms, using the observers experience to recognize morphologic patterns which will allow the identification of the structures.

Randomized clinical trial of the effect of intraoperative humidified carbon dioxide insufflation in open laparotomy for colorectal resection

BJS Open, Volume 4, Issue 1, Page 45-58, February 2020., 2020
Open abdominal surgery leads to peritoneal desiccation and damage, resulting in inflammation. This peritoneal damage can be mitigated by the use of warmed, humidified carbon dioxide. Peritoneal inflammation and open surgery Background Animal studies have shown that peritoneal injury can be minimized by insufflating the abdominal cavity with warm ...

π‐Extended COUPY Fluorophores for Targeted Near‐Infrared Fluorescence and Lifetime Imaging in Live Cells

Angewandte Chemie, Volume 138, Issue 34, 17 August 2026.
π‐Extended COUPY dyes, obtained by vinylogation of coumarin‐based COUPY scaffolds, shift absorption, and emission deep into the NIR region while preserving compactness and synthetic accessibility. These bright, photostable dyes enable live‐cell imaging, FLIM, and site‐specific peptide conjugation, offering a modular platform for targeted bioimaging and
