To solve these problems, novel structures were developed involving the polymer-based nanofibrous drug delivery systems [2,3]. The unique properties of the nanofibers as the high porosity with interconnected pore network and the increased surface area of the fibrous sheets, together with the active pharmaceutical ingredients can be embedded into the polymeric matrix carrier in an amorphous state, could lead to an increased dissolution and thus the bioavailability of drugs with a lower solubility [4,5]. Due to their structure, the formulation of nanofibrous materials loaded with different drugs have been widely used as drug delivery systems, scaffolds for tissue engineering and wound bandage. Electrospinning is a well controllable, simple and cost-effective technique for preparing matrices with nanometer-sized fibers with similar features and morphologies to the extracellular matrix (ECM) [6]. The ECM is the non-cellular component presents within all tissues and organs and plays a vital role in the wound healing process [7]. Therefore from those materials which can mimic their structure are believed to stimulate cell proliferation and could help the wound healing [6]. The diverse field of application of the nanofibrous materials required adequate functionalityrelated characteristics. One of the emerging improvements is the development of a bi-component core-shell fiber structure [8], which can offer several benefits for these samples: the core polymer/ composite can provide the required mechanical, physicochemical properties, and can control the release of the incorporated drug(s). The shell materials could preserve the unstable active pharmaceutical ingredients embedded into the core from the unfavorable environmental effect, which can increase the hydrophilicity and the biocompatibility of the fibrous samples. Besides that, one of the significant advantages of this core-shell nanostructures lies in the potential to tailor release properties of the incorporated drug and combine features of different polymers to achieve the required functionality-related characteristic and mechanical properties also [5].","PeriodicalId":6941,"journal":{"name":"Acta pharmaceutica Hungarica","volume":"62 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-11-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84413145","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Due to the obvious advantages, the green synthesis of nanoparticles is a rapidly progressing area of the nanobiotechnology. In line with this, the aim of this present study was to investigate the suitability of various green materials such as Parthenocissus quinquefolia plant extract and Phaffia rhodozyma cell-free extract for the preparation of iron nanoparticles (FeNPs), silver nanoparticles (AgNPs) and gold nanoparticles (AuNPs) by biological synthesis and to determine the toxicity of nanoparticles to human keratinocyte cells as well as against various fungal species with a special emphasis on antifungal efficiency against dermatophytes.","PeriodicalId":6941,"journal":{"name":"Acta pharmaceutica Hungarica","volume":"8 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-11-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82683520","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The formulation of such drugs as liposomal preparations enables to improve the bioavailability of these drugs. Berberine (BBR) is a quaternary isoquinoline alkaloid derived from many native plant species (Coptis spp., Berberis spp., Hydrastis canadensis etc.). BBR has been traditionally used for the treatment of different disorders including hyper-cholesterolemia and cardiovascular diseases [1,2]. BBR has a strong antimicrobial activity enabling the use of it as an anti-diarrheal, anti-protozoal, fungal, candida, yeast, and parasitic intestinal active ingredient [3]. In addition, BBR has shown an anti-inflammatory, anti-diabetic, lipid peroxidation, and neuroprotective activity [3,4]. Unfortunaterly, BBR is poorly soluble in water and has a low bioavailability (<10%) due to the induced activity of multidrug efflux transporter Pglycoprotein (P-gp) in the intestine itself [2]. Such limitations associated with a poor oral bioavailability of BBR could be overcome by nanoformulating BBR to liposomes. Pharmaceutical liposomes can be fabricated by ethanol-injection and thin-film hydration methods. The lamellarity, size, shape and ultra-structure of liposomes can be determined by using different advanced techniques, such as cryogenic electron microscopy (Cryo-EM), dynamic light scattering (DLS), size-exclusion chromatography (SEC), and atomic force microscopy (AFM) [5]. Confocal laser scanning microscopy (CLSM) has been also used for such imaging [6]. The aim of our study is to investigate ethanolinjection and film hydration methods for generating BBR-loaded liposomes and to study the structure, size, size distribution and entrapment efficiency of the liposomes. The liposomes are ultimately intended for the oral treatment of hypercholesterolemia.","PeriodicalId":6941,"journal":{"name":"Acta pharmaceutica Hungarica","volume":"20 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-11-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77176836","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore glycosylation considered as a CQA (Critical Quality Attribute) for biopharmaceutical products. At this point there is no routinely used, widespread analytical method to determine glycosylation. This may derive from the fact that the term glycosylation summarizes various features. The most often examined feature is the relative abundance of glycoforms. The position of different sugar residues within the oligosaccharide chain has been less frequently analyzed. In this study we have developed a method which, in addition to the commonly investigated features, determines the structural position of the fucose residue. We have examined glycosylation of three proteins: AGP (alpha-1-acid glycoprotein), PSA (Prostate Specific Antigen) and IgG (Immunoglobulin G).","PeriodicalId":6941,"journal":{"name":"Acta pharmaceutica Hungarica","volume":"16 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-11-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75879761","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
