Unusual case of bullous emphysema with superimposed pneumonia.

Bullous emphysema is a chronic obstructive pulmonary disease (COPD) that results from chronic inflammation of the lung parenchyma leading to alveolar destruction. Etiology includes tobacco smoking and alpha-1 antitrypsin deficiency. In this article, we present a rare case of bullous emphysema in a nonsmoker with no genetic predisposition or social risk factors presenting with productive cough, fatigue, and shortness of breath.

Gellan gum-based bi-polymeric hydrogel scaffolds loaded with Rosuvastatin calcium: A useful tool for tendon tissue regeneration.

Statins have been long used in tissue engineering, besides their marketed hypolipidemic benefits. The aim of this research was to sustain the release of rosuvastatin calcium from bi-polymeric hydrogel scaffolds. A bi-polymer blend technique was used to enhance the mechanical properties of the fabricated hydrogels.

Polymeric nanocomposite hydrogel scaffold for jawbone regeneration: The role of rosuvastatin calcium-loaded silica nanoparticles.

Bones are subject to different types of damages ranging from simple fatigue to profound defects. In serious cases, the endogenous healing mechanism is not capable of healing the damage or restoring the normal structure and function of the bony tissue. of this research was to achieve a sustained delivery of rosuvastatin and assess its efficacy in healing bone tissue damage.

Conventional and Recent Trends of Scaffolds Fabrication: A Superior Mode for Tissue Engineering.

Tissue regeneration is an auto-healing mechanism, initiating immediately following tissue damage to restore normal tissue structure and function. This falls in line with survival instinct being the most dominant instinct for any living organism. Nevertheless, the process is slow and not feasible in all tissues, which led to the emergence of tissue engineering (TE).

Design and characterization of highly porous curcumin loaded freeze-dried wafers for wound healing.

The goal of this research was to evaluate the beneficial effects of topical curcumin loaded freeze-dried wafers in wound healing. Curcumin wafers were fabricated by cross-linking of chitosan with beta glycerophosphate under magnetic stirring. Composite wafers were prepared by the addition of sodium hyaluronate.

Design and Characterization of Spray-Dried Proliposomes for the Pulmonary Delivery of Curcumin.

Purpose: The goal was to directly deliver curcumin, a natural polyphenolic anticancer and anti-inflammatory compound, to the lung tissues with minimal systemic exposure through the fabrication of proliposomes, overcoming its poor aqueous solubility and oral bioavailability.

Methods: Nano-spray drying was employed to prepare proliposomes using hydroxypropyl beta-cyclodextrin as a carrier. Lecithin and cholesterol were used as lipids, stearylamine and Poloxamer 188 were added as positive charge inducer and a surfactant, respectively.

Respiratory Tract: Structure and Attractions for Drug Delivery Using Dry Powder Inhalers.

Respiratory tract is one of the oldest routes for drug delivery. It can be used for local and systemic drug deliveries. Inhalation therapy has several advantages over oral.
