Snake venoms from the Viperidae and Elapidae families often have several phospholipases A2 (PLA2s), which may display different functions despite having a similar structural scaffold. These proteins are considered an important target for the development of drugs against local myotoxic damage because they are not efficiently neutralized by conventional serum therapy. PLA2s from these venoms are generally divided into two classes: (i) catalytic PLA2s (or Asp49-PLA2s) and (ii) non-catalytic PLA2-like toxins (or Lys49-PLA2s)...

BACKGROUND: Regardless of the device used, many patients have difficulty maintaining proper inhaler technique over time. Repeated education from caregivers is required to ensure persistence of correct inhaler technique, but no information is available to evaluate the time required to rectify inhaler errors in experienced users with a baseline faulty technique and whether this time of re-education to restore inhaler mastery can differ between devices. METHODS: This was a multi-center, single-visit, open-label, cross-sectional study in a large group of 981 experienced adult subjects (mean ± SD age 64 ± 15 y), mainly suffering from COPD and asthma, who showed faulty inhaler technique at a follow-up visit in chest clinics...

In 1956, Riker Laboratories, Inc., (now 3 M Drug Delivery Systems) introduced the first pressurized metered dose inhaler (MDI). In many respects, the introduction of the MDI marked the beginning of the modern pharmaceutical aerosol industry. The MDI was the first truly portable and convenient inhaler that effectively delivered drug to the lung and quickly gained widespread acceptance. Since 1956, the pharmaceutical aerosol industry has experienced dramatic growth. The signing of the Montreal Protocol in 1987 led to a surge in innovation that resulted in the diversification of inhaler technologies with significantly enhanced delivery efficiency, including modern MDIs, dry powder inhalers, and nebulizer systems...

TAK-475 (lapaquistat acetate) and its active metabolite-I (TAK-475 M-I) inhibit squalene synthase, which catalyzes the conversion of farnesyl diphosphate (FPP) to squalene. FPP is a substrate for synthesis of other mevalonate-derived isoprenoids (MDIs) such as farnesol (FOH), geranlygeranyl diphosphate (GGPP), and geranylgeraniol. In patients with MKD, a rare autosomal recessive disorder, defective activity of mevalonate kinase leads to a shortage of MDIs. MDIs especially GGPP are required for prenylation of proteins, which is a posttranslation modification necessary for proper functioning of proteins like small guanosine triphosphatases...

Studies show the delivery of inhaled medications is maximized when a metered-dose inhaler (MDI) with a spacer is utilized. Our residents expressed concern with their knowledge of MDIs and spacers. This study was designed to address those concerns. Residents were given a 12-question pre-intervention, self-assessment questionnaire that explored their overall knowledge and comfort in utilizing MDI with spacers. Participants then received educational intervention via multimedia videos and a demonstration of proper use of MDI with spacer...

Despite frequent use of metered dose inhalers (MDIs) and spacers in equine practice, limited information exists on the efficiency of aerosol delivery using such devices. We determined the particle size distribution within an MDI-generated salbutamol aerosol delivered via an equine spacer using 'best practice' delivery technique and assessed the effect of variations in MDI use technique (shaking prior to each actuation, rapid repetitive actuations, and MDI angulation) on aerosol delivery efficiency. Under optimal conditions, only 53(±18) μg salbutamol per 100 μg actuation was delivered beyond the spacer...

Mammalian cells can utilize hydrogen sulfide (H2S) to support mitochondrial respiration. The aim of our study was to explore the potential role of S-sulfhydration (a H2S-induced posttranslational modification, also known as S-persulfidation) of the mitochondrial inner membrane protein ATP synthase (F1F0 ATP synthase/Complex V) in the regulation of mitochondrial bioenergetics. Using a biotin switch assay, we have detected S-sulfhydration of the α subunit (ATP5A1) of ATP synthase in response to exposure to H2S in vitro...

The human cornea is rich in extracellular matrix. The stroma constitutes the main thickness of the cornea, which consists of collagens and proteoglycans mainly. The epithelial-stromal and stromal dystrophies of the cornea are either autosomal dominant or recessive inherited disorders, which are unrelated to inflammation or trauma. The diseases can manifest in each layer of the cornea, but in most cases the corneal stroma is affected. Generally, they develop in childhood or young adulthood but the diagnosis is only possible when clinical signs (epithelial erosions, decreased visual acuity, photophobia) develop...

PURPOSE: Respiratory drug delivery has been attracted great interest for the past decades, because of the high incidence of pulmonary diseases. However, despite its invaluable benefits, there are some major drawbacks in respiratory drug delivery, mainly due to the relatively high drug deposition in undesirable regions. One way to improve the efficiency of respiratory drug delivery through metered-dose inhalers (MDI) is placing a respiratory spacer between the inhaler exit and the mouth...
