Dose dumping of modified-release solid oral dosage forms.

The presented review article is a compilation of several foreign reviews and experimental papers, as well as several authority guidelines, which deal with the phenomenon of dose dumping of solid dosage forms with modified drug release. The aim of the publication is to present this often-neglected issue to a wider domestic audience. The work deals with two basic types of dose dumping, i.

The Acute Immune Responses of the Common Carp to PLGA Microparticles-The Interactions of a Teleost Fish with a Foreign Material.

Poly lactic-co-glycolic acid (PLGA) particles safely and effectively deliver pharmaceutical ingredients, with many applications approved for clinical use in humans. In fishes, PLGA particles are being considered as carriers of therapeutic drugs and vaccine antigens. However, existing studies focus mainly on vaccine antigens, the endpoint immune responses to these (e.

Identifying pathways regulating the oncogenic p53 family member ΔNp63 provides therapeutic avenues for squamous cell carcinoma.

Background: ΔNp63 overexpression is a common event in squamous cell carcinoma (SCC) that contributes to tumorigenesis, making ΔNp63 a potential target for therapy.

Methods: We created inducible TP63-shRNA cells to study the effects of p63-depletion in SCC cell lines and non-malignant HaCaT keratinocytes. DNA damaging agents, growth factors, signaling pathway inhibitors, histone deacetylase inhibitors, and metabolism-modifying drugs were also investigated for their ability to influence ΔNp63 protein and mRNA levels.

Use of droplet-based microfluidic techniques in the preparation of microparticles.

Microparticles are widely used in myriad fields such as pharmaceuticals, foods, cosmetics, and other industrial fields. Compared with traditional methods for synthesizing microparticles, microfluidic techniques provide very powerful platforms for creating highly controllable emulsion droplets as templates for fabricating uniform microparticles with advanced structures and functions. Microfluidic techniques can generate emulsion droplets with precisely controlled size, shape, and composition.

Exploration of Neusilin US2 as an Acceptable Filler in HPMC Matrix Systems-Comparison of Pharmacopoeial and Dynamic Biorelevant Dissolution Study.

Modern pharmaceutical technology still seeks new excipients and investigates the further use in already known ones. An example is magnesium aluminometasilicate Neusilin US2 (NEU), a commonly used inert filler with unique properties that are usable in various pharmaceutical fields of interest. We aimed to explore its application in hypromellose matrix systems (HPMC content 10-30%) compared to the traditionally used microcrystalline cellulose (MCC) PH 102.
