Synthesis, modification, and chlorhexidine loading of polymer modified‐HM‐HAP particles: In vivo antibacterial analysis and cell cytotoxicity assessment

Smart Molecules, EarlyView.
This study presents the synthesis of hollow mesoporous hydroxyapatite (HM‐HAP) particles modified with different weights PEG and PEI. Chlorhexidine was loaded onto the particles. SEM analysis confirmed no significant morphological changes. Antibacterial activity was tested in vitro and in vivo using mouse oral bacteria, demonstrating promising results.

Volatile anesthetics in cardiac surgery: the impalpable benefit

, 2018
Nowadays, there are numerous studies demonstrating that volatile anesthetics reduce mortality and morbidity with a cardio-protective effect. The mechanisms involved in protecting perioperative cardiac ischemic damage provided by desflurane and ...

Agricultural Fungicide Mancozeb in Leaf Litter Enhances Survival and Growth of Aedes aegypti (Diptera: Culicidae)

Environmental Toxicology, EarlyView.
ABSTRACT Mancozeb is one of the most widely used agricultural fungicides, exhibiting strong efficacy against a broad spectrum of phytopathogenic fungi. However, its widespread application comes at the cost of environmental contamination. Here, we show the effects of Inga vera leaf litter contamination with Mancozeb on life‐history traits of Aedes ...

Volatile anesthetics inhibit voltage-dependent Ca2+ channels in porcine tracheal smooth muscle cells

, 1995
The relaxation of airway smooth muscle by volatile anesthetics is associated with a decreased concentration of intracellular free Ca2+. We hypothesized that inhibition of the entry of extracellular Ca2+ contributes to the relaxation.

From the Cover: Volatile Anesthetics Transiently Disrupt Neuronal Development in Neonatal Rats [PDF]

, 2016
Volatile anesthetics can cause neuronal and glial toxicity in the developing mammalian brain, as well as long-term defects in learning and memory. The goals of this study were to compare anesthetics using a clinically relevant exposure paradigm, and to ...

Artemia salina Toxicity Assay: Standardization in a 24‐Well Microplate

Environmental Toxicology, EarlyView.
ABSTRACT Bioassays with Artemia sp. are widely used in aquatic, environmental, and human toxicology as an initial tool to investigate the toxicity of plant extracts, isolated compounds, drugs, and products of natural or synthetic origin. These assays allow for the estimation of the median lethal concentration (LC50) and guide subsequent studies in ...

Effects of perioperative anesthetics on the postoperative prognosis of patients undergoing surgery for cervical cancer

Frontiers in Pharmacology
Cervical cancer is a common malignancy among women, and tumor excision is the most common surgical intervention. Anesthetics used during surgery include general intravenous, volatile, local anesthetics, sedative and analgesic. Studies have shown that the

Effects of surgery and anesthetic choice on immunosuppression and cancer recurrence

Journal of Translational Medicine, 2018
Background The relationship between surgery and anesthetic-induced immunosuppression and cancer recurrence remains unresolved. Surgery and anesthesia stimulate the hypothalamic–pituitary–adrenal (HPA) axis and sympathetic nervous system (SNS) to cause ...

Cardioprotection with volatile anesthetics in cardiac surgery

, 2008
Myocardial ischemia during the perioperative period is a major cause of morbidity and mortality after surgery. Experimental data indicate that clinical concentrations of volatile anesthetics protect the myocardium from ischemia and reperfusion injury, as

Rapid Eye Movement Sleep Debt Accrues in Mice Exposed to Volatile Anesthetics

, 2011
Background General anesthesia has been likened to a state in which anesthetized subjects are locked out of access to both rapid eye movement (REM) sleep and wakefulness.
