Differential intestinal injury and unchanged systemic inflammatory responses to leg and whole‐body passive hyperthermia in healthy humans

Experimental Physiology, EarlyView.
Abstract Hyperthermia can cause intestinal injury, facilitating endotoxin translocation and an inflammatory response that has been associated with heat illness. However, the potential occurrence of these responses has been incompletely reported during passive hyperthermia, and the independent effect of hyperthermia is equivocal.

Increases in skin perfusion and blood oxygen in the non‐exercising human limbs during exercise in the heat: Implications for control of circulation

Experimental Physiology, EarlyView.
Abstract Blood flow in the inactive limb tissues and skin is widely thought to decline during incremental exercise to exhaustion due to augmented sympathoadrenal vasoconstrictor activity, but direct evidence to support this view is lacking. Here, we investigated the inactive‐forearm haemodynamic (Q̇forearm${\dot{Q}}_{\mathrm{forearm}}$) and oxygenation

Prilocaine-Induced Methemoglobinemia During Surgically Assisted Rapid Palatal Expansion (SARPE) Under General Anesthesia: A Case Report

Case Reports in Dentistry
Methemoglobinemia is a condition in which methemoglobin levels in the blood increase. Methemoglobin lacks oxygen-binding ability, resulting in oxygen deprivation in tissues.

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.

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.

1,4-diaminobenzene and diphenylamine-induced severe methemoglobinaemia treated by hyperbaric oxygen therapy – Case report

Medycyna Pracy, 2018
Methemoglobin is an oxidized form of hemoglobin that is not capable of carrying oxygen. Exposure to exogenous oxidizing agents can cause severe methemoglobinemia and subsequent hypoxia.

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 ...

A Novel Plasma Heme Assay Reveals Disease Severity in Beta‐Thalassemia and Sickle Cell Anemia

American Journal of Hematology, Volume 101, Issue 7, Page 1706-1716, July 2026.
ABSTRACT Anemia results from imbalanced hemoglobin or red blood cell production and clearance. Hemolytic anemia, caused by premature red blood cell removal, can be intravascular (in blood) or extravascular (erythrophagocytosis). Hemolysis is common in Sickle Cell Disease (SCD) and Beta‐Thalassemia anemia (β‐thalassemia), the most prevalent inherited ...

Cold Gas Plasma Induces Platelet Activation and Hemostasis in Native and Anticoagulated Human Blood

Advanced NanoBiomed Research, Volume 6, Issue 7, July 2026.
Cold physical gas plasma induces platelet activation and hemostatic responses in native and anticoagulated human blood. Treatment efficacy depends on plasma parameters, including gas composition, distance, and exposure mode, which govern reactive species delivery and energy transfer.

ADAPTAÇÃO DA METODOLOGIA DE ANÁLISE DE METEMOGLOBINA COMO BIOMARCADOR DE EFEITO DA EXPOSIÇÃO AO AGROTÓXICO DIFLUBENZURON

Química Nova, 2015
This work aimed to adapt the analysis of methemoglobin recommended by Evelyn - Malloy (visible spectrophotometry), in order to facilitate its application in the field, or to analysis in clinical laboratory, of existing sites of diflubenzuron application.
