Additive Manufacturing of Prostheses Using Forest-Based Composites.

A custom-made prosthetic product is unique for each patient. Fossil-based thermoplastics are the dominant raw materials in both prosthetic and industrial applications; there is a general demand for reducing their use and replacing them with renewable, biobased materials. A transtibial prosthesis sets strict demands on mechanical strength, durability, reliability, etc.

Aerosol drug delivery to the lungs during nasal high flow therapy: an in vitro study.

Background: Aerosol delivery through a nasal high flow (NHF) system is attractive for clinicians as it allows for simultaneous administration of oxygen and inhalable drugs. However, delivering a fine particle fraction (FPF, particle wt. fraction < 5.

Storage stability of inhalable phage powders containing lactose at ambient conditions.

The aim of this study was to evaluate the storage stability of inhalable phage powders containing lactose and leucine as excipient. As an FDA-approved excipient for inhalation, lactose is preferred over other sugars. PEV phages active against antibiotic-resistant Pseudomonas aeruginosa was spray dried with lactose (55-90%) and leucine (45-10%).

Studies of Radioaerosol Deposition in the Respiratory Tract.

Deposition of aerosols in the respiratory tract can be quantitatively and qualitatively studied by scintigraphy. The most commonly used radionuclide for this purpose is technetium-99m. The effects of various factors on particle deposition have been investigated by using radiolabeled aerosols in the past decade.

Crystal structure of aqua-(2-{[2-({2-[bis-(carboxyl-ato-κ-meth-yl)amino-κ]eth-yl}(carboxyl-ato-κ-meth-yl)amino-κ)eth-yl](carb-oxy-meth-yl)aza-niumyl}acetato)-gallium(III) trihydrate.

In the title Ga complex compound with pentetic acid, [Ga(CHNO)(HO)]·3HO, the Ga centre is bound in a slightly distorted octa-hedral coordination sphere by two amine N atoms, three carboxyl-ate O atoms and one water O atom. The complex mol-ecule exists as a zwitterion. In the crystal, the complexes are linked to each other O-H⋯O and C-H⋯O hydrogen bonds, forming layers parallel to (001).

Phage therapy for respiratory infections.

A respiratory infection caused by antibiotic-resistant bacteria can be life-threatening. In recent years, there has been tremendous effort put towards therapeutic application of bacteriophages (phages) as an alternative or supplementary treatment option over conventional antibiotics. Phages are natural parasitic viruses of bacteria that can kill the bacterial host, including antibiotic-resistant bacteria.

Pulmonary drug delivery to older people.

Pulmonary diseases, such as asthma and chronic obstructive pulmonary disease (COPD), are common in older people. Treatment principles are well established in this group of patients; however, inadequate training and improper inhaler techniques often results in poor treatment outcomes. Healthcare professionals often do not have the required knowledge about the most common inhaler devices.

Proof-of-Principle Study in a Murine Lung Infection Model of Antipseudomonal Activity of Phage PEV20 in a Dry-Powder Formulation.

Bacteriophage therapy is a promising alternative treatment to antibiotics, as it has been documented to be efficacious against multidrug-resistant bacteria with minimal side effects. Several groups have demonstrated the efficacy of phage suspension to treat lung infections using intranasal delivery; however, phage dry-powder administration to the lungs has not yet been explored. Powder formulations provide potential advantages over a liquid formulation, including easy storage, transport, and administration.
