Light-Sensitive Injectable Prescription Drugs-2022.

This chart is an update to the 2014 article published in Hospital Pharmacy on injectable drugs that require protection from light. To update the chart, an online search of the FDALabel database was performed from inception through July 31, 2022 using the terms "protect" OR "light." After filtering out drugs with non-injectable routes of administration, the list of generic drug names was combined with the 2014 list and duplicates were removed.

Cluster analysis of indoor environmental factors associated with symptoms of mite allergy.

Background: The clinical efficacy of controlling environmental allergens as a component of allergic asthma treatment remains controversial. Multifaceted allergen reductions appeared to be the most efficient methods. However, they require home visits with indoor technicians.

Mouse (Mus m1) and rat (Rat n1) allergen levels in dust from private and public houses in Strasbourg, France are lower than houses in the U.S.A.

The aim of our study was to measure the concentration of Mus m1 and Rat n1 in randomly selected dwellings in Strasbourg and the suburbs.

Effects of PM2.5 components in the release of amphiregulin by human airway epithelial cells.

Exposure to ambient particulate matter (PM) is responsible for airway inflammation and tissue remodeling. Urban PM(2.5) (aerodynamic diameter <2.

Responses of well-differentiated nasal epithelial cells exposed to particles: role of the epithelium in airway inflammation.

Numerous epidemiological studies support the contention that ambient air pollution particles can adversely affect human health. To explain the acute inflammatory process in airways exposed to particles, a number of in vitro studies have been performed on cells grown submerged on plastic and poorly differentiated, and on cell lines, the physiology of which is somewhat different from that of well-differentiated cells. In order to obtain results using a model system in which epithelial cells are similar to those of the human airway in vivo, apical membranes of well-differentiated human nasal epithelial (HNE) cells cultured in an air-liquid interface (ALI) were exposed for 24 h to diesel exhaust particles (DEP) and Paris urban air particles (PM(2.

TGF-beta 1 downregulates CFTR expression and function in nasal polyps of non-CF patients.

Nasal polyposis is a chronic inflammatory disease of the upper airways. It has been suggested that ion transports and CFTR expression could be modified in epithelial cells from nasal polyps of non-cystic fibrosis patients. We compared human nasal epithelial cells from nasal polyps (NP) with control nasal mucosa (CM).

The toxicity of H2O2 on the ionic homeostasis of airway epithelial cells in vitro.

Oxygen species may be formed in the air spaces of the respiratory tract in response to environmental pollution such as particulate matter. The mechanisms and target molecules of these oxidants are still mainly unknown but may involve modifications of the ionic homeostasis in epithelial cells. Cytosolic concentrations of Ca2+ (Fura2) and Na+ (SBFI) and short-circuit current (Isc) were followed in primary cultures of human nasal epithelial cells and in the cell line 16HBE14o- after exposure to H2O2 or *OH (H2O2 + Fe2+).

Effects of hydrogen peroxide and hydroxyl radicals on the cytosolic side of a non-selective cation channel in the cultured human bronchial epithelial cell line 16HBE14o-.

Respiratory tissues can be damaged by the exposure of airway epithelial cells to reactive oxygen species (ROS) that generate an oxidative stress. We studied the effects of the hydroxyl radical *OH, for which there is no natural intra- or extracellular scavenger, on a Ca2+-activated, non-selective cation channel (NSC(Ca)) which might participate in the transepithelial Na+ fluxes involved in the maintenance of the cytosolic [Na+] ([Na+]i). We identified and characterized NSC(Ca) in inside-out excised membrane patches from cells of the human bronchial cell line 16HBE14o- and exposed the cytoplasmic side of NSC(Ca) to H2O2 or *OH created in front of the patch pipette.

Effects of hydroxyl radicals on outwardly rectifying chloride channels in a cultured human bronchial cell line (16HBE14o-).

Respiratory pathologies can result from the exposure of airway epithelial cells to oxidative stress. We studied the effects of the hydroxyl radical *OH, for which there is no natural intra- or extracellular scavenger, on an outwardly rectifying chloride channel (ORCC). In the human bronchial cell line 16HBE14o-, the cytoplasmic side of ORCC in inside-out excised membrane patches was exposed to *OH created by simultaneously superfusing Fe2+ and H2O2 in front of the patch-pipette.

Differential effects of maitotoxin on calcium entry and ciliary beating in the rabbit ciliated tracheal epithelium.

The marine toxin maitotoxin (MTX) induces stimulation of ciliary beating in primary cultures of rabbit tracheal epithelial cells. The response is time- and concentration-dependent. External calcium is an absolute requirement, although at a very low concentration (50 microM for maximal effect).

Effects of maitotoxin on calcium entry and phosphoinositide breakdown in the rabbit ciliated tracheal epithelium.

Maitotoxin induces a concentration-dependent 45Ca uptake in primary cultures of rabbit tracheal epithelial cells. This response is insensitive to the calcium channel antagonists nifedipine, diltiazem and verapamil up to 20 microM. However, verapamil at 200 microM completely prevents 45Ca uptake.

Measurement of the epithelial barrier integrity in tracheal cell cultures exposed to irritant compounds.

A simple method has been developed to measure epithelial barrier alteration, in order to evaluate the irritant effect of inhaled compounds on the respiratory tract. In vitro primary cell cultures from rabbit tracheal epithelium were grown on permeable filters and used to study the effect of two pollutants-acrolein and parathion-on epithelial barrier integrity. The transepithelial potential difference and [(14)C]mannitol permeability were measured.
