Methaemoglobinaemia: From pathophysiology to contemporary clinical management

British Journal of Haematology, Volume 209, Issue 3, Page 900-910, September 2026.
Summary Methaemoglobin (MetHb) is an oxidised form of haemoglobin (Hb) unable to bind oxygen. Raised levels of MetHb reduce the blood's oxygen‐carrying capacity, causing potentially severe hypoxaemia and possible death. The condition arises from three main pathologies: mutations in globin genes causing Haemoglobin‐M, inherited deficiency of the enzyme ...

VITAMINE C EFFECT ON SILVER NITRATE INDUCED METHEMOGLOBINEMIA:ANIMAL STUDY

Journal of Research in Medical Sciences, 2001
Introduction. Methemoglobinemia is a condition characterized by increased quantities of hemoglobin in which the iron of heme is oxidized to the ferric(Fe3+) form. Methemoglobin is useless as an oxygen carrier and thus causes a varying degree of cyanosis.

Time‐dependent laryngeal desensitisation following topical lidocaine and prilocaine application in cats: a randomised controlled study

Journal of Small Animal Practice, Volume 67, Issue 9, Page 836-842, September 2026.
Objectives To compare the effects of topical prilocaine and lidocaine, relative to topical 0.9% sodium chloride, on laryngeal reactivity in anaesthetised cats prior to endotracheal intubation. Materials and Methods In this prospective, randomised, controlled, double‐blind study, 24 healthy adult cats were enrolled and allocated to topical prilocaine ...

Numerical study of the effect of methemoglobin concentration in the blood on the absorption of light by human skin

Научно-технический вестник информационных технологий, механики и оптики
Lasers are widely used in dermatology to remove telangiectasias. Increasing the effciency of sclerosis of deep-lying and large telangiectasias with laser radiation is possible by changing the optical transmission of the skin when it is heated and ...

Rational Design of Bimetallic MOF‐Derived Cu/Co@N‐C Nanocubes for Ultrasensitive Electrochemical Nitrite Detection

Rare Metals, Volume 45, Issue 8, August 2026.
ABSTRACT A facile coprecipitation‐pyrolysis strategy was employed to fabricate Cu/Co nanoparticles (NPs) embedded in nitrogen‐doped carbon matrices (Cu/Co@N‐C) through the carbonization of CuCo‐MOF precursors. Moreover, monometallic counterparts of Cu@N‐C and Co@N‐C were also prepared via carbonization of bimetallic CuZn‐MOF and CoZn‐MOF, respectively.
