On the Relentless Pursuit of an Oral Insulin Delivery System: How Far is Too Far?

open access: yesAdvanced Therapeutics, EarlyView.
Injectable insulin preparations have far outpaced oral ones by virtue of adequate bioavailability and are driven by innovations, including insulin pumps, real‐time blood glucose monitoring, and artificial intelligence. In contrast, oral insulin delivery systems, including nanomedicines, continue to struggle and lag due to varied reasons.

Single inhalation exposure to polyamide micro and nanoplastic particles impairs vascular dilation without generating pulmonary inflammation in virgin female Sprague Dawley rats

open access: yesParticle and Fibre Toxicology, 2023
Background Exposure to micro- and nanoplastic particles (MNPs) in humans is being identified in both the indoor and outdoor environment. Detection of these materials in the air has made inhalation exposure to MNPs a major cause for concern.

Pulmonary drug delivery and retention: a computational study to identify plausible parameters based on a coupled airway-mucus flow model [PDF]

open access: yesarXiv, 2020
Pulmonary drug delivery systems rely on inhalation of drug-laden aerosols produced from aerosol generators such as inhalers, nebulizers etc. On deposition, the drug molecules diffuse in the mucus layer and are also subjected to mucociliary advection which transports the drugs away from the initial deposition site.

Nonhuman Primate Models of Respiratory Disease: Past, Present, and Future. [PDF]

open access: yes, 2017
The respiratory system consists of an integrated network of organs and structures that primarily function for gas exchange. In mammals, oxygen and carbon dioxide are transmitted through a complex respiratory tract, consisting of the nasal passages ...

Inhibiting the Histone Demethylase Kdm4a Restrains Cardiac Fibrosis After Myocardial Infarction by Promoting Autophagy in Premature Senescent Fibroblasts

open access: yesAdvanced Science, EarlyView.
Kdm4a downregulation restrains excessive cardiac interstitial fibrosis and remodeling by depressing the premature senescence of fibroblasts in the advanced stage after MI but does not affect early ventricular rupture. It verified that Kdm4a downregulation promotes autophagy in premature senescent fibroblasts by increasing the H3K9m3 modification of the

Adults with well‐healed burn injuries have lower pulmonary function values decades after injury

open access: yesPhysiological Reports, 2022
Sub‐acute (e.g., inhalation injury) and/or acute insults sustained during a severe burn injury impairs pulmonary function. However, previous work has not fully characterized pulmonary function in adults with well‐healed burn injuries decades after an ...

Pulmonary embolism and oxygen inhalation

open access: yesKazan medical journal, 2021
Prof. G. Lotheissen (Zentrbl. F. Chir. No. 41. 1929) saw success from inhalation of oxygen in pulmonary embolism and suggests using it when it is impossible to perform the Trendelenburg operation.

Review of hypoxaemia in the anaesthetized horse: predisposing factors, consequences and management [PDF]

open access: yes, 2017
Objectives: To discuss how hypoxaemia might be harmful and why the horse is particularly predisposed to developing it. To review the strategies that are used to manage hypoxaemia in anaesthetised horses, to describe how successful these strategies are

MMP9High Neutrophils are Critical Mediators of Neutrophil Extracellular Traps Formation and Myocardial Ischemia/Reperfusion Injury

open access: yesAdvanced Science, EarlyView.
During a heart attack, neutrophils rapidly activate and differentiate into a specific subset characterized by high levels of MMP9, a tissue‐damaging enzyme, via the SPI1/CST7 pathway. These neutrophils form harmful net‐like structures (Neutrophil extracellular traps, NETs) that exacerbate heart injury.

Inhaled tolafentrine reverses pulmonary vascular remodeling via inhibition of smooth muscle cell migration

open access: yesRespiratory Research, 2005
Background The aim of the study was to assess the chronic effects of combined phosphodiesterase 3/4 inhibitor tolafentrine, administered by inhalation, during monocrotaline-induced pulmonary arterial hypertension (PAH) in rats. Methods CD rats were given
