Microsponges as promising vehicle for drug delivery and targeting: Preparation, characterization and applications

Development of novel drug delivery systems for optimization of drugs’ efficacy and cost-effectiveness has become highly competitive and rapidly evolving area of interest. Controlling the delivery rate of drugs to a predetermined site has been one of the biggest challenges faced by formulators. Amongst the novel drug delivery systems that proved their efficacy in achieving controlled drug release are microsponges....

The effects of aqueous extracts of Hibiscus sabdariffa Linn. calyces of var. ruber and var. intermedius on intestinal transit in rats

The effects of aqueous extracts of Hibiscus sabdariffa l. calyces of var. ruber and var. intermedius on intestinal transit were determined in experimental rats. The dried calyces of H. sabdariffa l. were pulverized and 10% extracts of both var. ruber and var. intermedius were made and administered orally at varying doses. Test rats were given the 10% extracts...

Effect of seawater immersion on the NF-κB, IκB and TLR4 expression in small intestinal tissues in rats with abdominal open injury

The aim of this study was to observe the impact of seawater immersion on the dynamic expressions of NF-κB and IκB mRNA in small intestinal tissues in rats with abdominal open injury. Wistar rats were randomly divided into three groups: the control group (n = 7), the abdominal open injury (AOI) group and abdominal open injury plus seawater immersion (AOI+SI) group. The dynamic expressions...

Towards a new economic model on biopharmaceutical companies

Intangible assets are one of the most important issues in biopharmaceutical companiestoday, due to the idiosyncrasies of this business. In such an innovative sector, companies have been investing heavily in research, development and innovation and the book value often does not accurately reflect the real value of the companies. It was necessary, therefore, a new accounting model that meets the needs of this sector....

Antioxidant and anticancer activities of methanolic extract of Trollius chinensis Bunge

The flower of Trollius chinensis Bunge (Flos trollii) is used for treating upper respiratory infections, pharyngitis, tonsillitis and bronchitis as a Chinese folk medicine since ancient times. This study aimed to investigate possible antioxidant and anticancer activity of methanolic extract of F. trollii (FTME). The antioxidant activity of FTME was determined by...

The activity against methicillin-resistant Staphylococcus aureus and quantitative structure-activity relationship (QSAR) study of aza-naphthindolizinedione derivatives

The antibacterial activity of aza-naphthindolizinedione derivatives has been determined. Three compounds, 15, 21 and 40 exhibited strong inhibitory activity against Gram-positive bacterial strains and especially, showed 16 times activity better than vancomycin against methicillin-resistant Staphylococcus aureus (MRSA). Quantitative structure-activity relationship (QSAR) study indicated that the proposed method...

Inhibition of α-amylase and α-glucosidase activities by ethanolic extract of Amaranthus cruentus leaf as affected by blanching

This study investigated the inhibitory effect of Amaranthus cruentus leaf on key enzyme linked to type-2 diabetes (α-amylase and α-glucosidase) as well as assessing the effect of blanching (a commonly practiced food processing technique) of the vegetable on these key enzymes. Fresh leaves of A. cruentus were blanched in hot water for 10 min, and the ethanolic extracts of both the fresh...

Effect of dexmedetomidine on myocardial oxygen consumption during extubation for old patients: A bispectral index-guided observation study

The aim of this study was to investigate the effect of dexmedetomidine (DEX) maintenance on myocardial oxygen consumption during extubation for generally-anesthetized old patients under bispectral index (BIS) monitoring. A total of 40 patients who were subjected to thyroid operation and laparoscopic cholecystectomy under general anesthesia (ASA I or II) were randomized into the experimental (n = 20) and control (n = 20)...

Synthesis and characterization of folic acid-conjugated human serum albumin (HSA) nanoparticles for isoalantolactone cellular uptake in HeLa

Folic acid was previously demonstrated to mediate intracellular nanoparticle uptake. Isoalantolactone (IAL) was demonstrated to possess a variety of pharmacological activities in vivo and in vitro, including cytotoxic, diuretic and immunosuppressive activity. Here, we developed folic acid-conjugated human serum albumin nanoparticles for IAL (FHNs-IAL) encapsulation to improve the...

Molecular cloning and characterization of a new cDNA encoding a trypsin-like serine protease from the venom gland of Scolopendra subspinipes mutilans

A cDNA encoding a new putative serine protease, named Ssmase, was cloned and characterized from the venom gland of the centipede Scolopendra subspinipes mutilans. The cDNA sequence was 1029 bp length, including a 780 bp open reading frame (ORF), a 105 bp 5’ untranslated region, and a 144 bp 3’ untranslated region. The precursor nucleotide sequence of Ssmase was deduced to encode a...

Simultaneous determination of organic acids and iridoid glycosides in traditional Chinese medicine (TCM) preparation reduning injection by rapid resolution liquid chromatography (RRLC) with ultraviolet (UV) detection under segmental monitoring mode

A sensitive method of the simultaneous determination of organic acids and iridoid glycoside in reduning injection was described by rapid resolution liquid chromatography (RRLC) with ultraviolet (UV) detection under segmental monitoring mode. RRLC separation was achieved by use of a C18 analytical column packed with sorbent of particle size 1.8 μm while the injected sample volume was set to 2 µl. A binary...
