The dose-dependent neuroprotective effect of norepinephrine in improving memory retrieval in an experimental model of multiple sclerosis, experimental autoimmune encephalomyelitis.

Multiple sclerosis (MS) is considered an immune-mediated inflammatory disorder that causes cognitive impairments by damaging the hippocampal tissue. Conversely, norepinephrine (NEP) has anti-inflammatory and re-myelinating properties, which improve cognitive impairments. The aim of this study was to assess the neuroprotective effects of NEP on learning and memory disorders in an experimental animal model of MS.

Micronutrients status as a contributing factor in secondary burning mouth syndrome: A review of the literature.

Background And Aims: Patients with burning mouth syndrome (BMS) experience an annoying feeling without clinical evidence of any mucosal lesion. Deficiency or excess of micronutrients is a common feature in secondary BMS. There is limited knowledge among oral healthcare providers regarding the significance of micronutrients in oral health, so the current review focuses on the critical role of these elements in oral health implications as secondary BMS.

Patients with a baseline β-HCG< 4800 mIU/mL received single-dose MTX (n = 136) and those with an initial β-HCG≥ 4800 mIU/mL underwent the double-dose MTX regimen (n = 48).

Preparation, Optimization and Characterization of Fluticasoneloaded Mixed Micelles Based on Stearic Acid-g-chitosan as a Pulmonary Delivery System.

Purpose: The primary objective of this study was to optimize formulation variables and investigate the characteristics of fluticasone propionate (FP)-loaded mixed polymeric micelles, which were composed of depolymerized chitosan-stearic acid copolymer (DC-SA) in combination with either tocopheryl polyethylene glycol succinate or dipalmitoylphosphatidylcholine for pulmonary drug delivery.

Methods: A D-optimal design was employed for the optimization procedure, considering lipid/ polymer ratio, polymer concentration, drug/ polymer ratio, and lipid type as independent variables. Dependent variables included particle size, polydispersion index, zeta potential, drug encapsulation efficiency, and loading efficiency of the polymeric micelles.

Long-Term Clinical and Imaging Findings in Patients with Lower Extremity Varicose Veins Treated with Endovenous Laser Treatment: A Follow-Up Study of up to 12 Years.
