some drugs have low bioavailability due to their poor aqueous solubility and/or slowdissolution rate in biological fluids. stiripentol (stp) is a novel anticonvulsant drug that isstructurally unrelated to the currently available antiepileptics. it has poor aqueous solubilityand its solubility has to be enhanced accordingly. polyethyleneglycol 6000 (peg-6000) iscommonly utilized as a hydrophilic...

in order to enhance in vitro dissolution and content uniformity of poorly soluble drug glimepiride by preparing solid dispersions using modified solvent fusion method, solid dispersions of drug were prepared by modified fusion solvent method using peg 6000 and pvp k25 (as carrier). eight batches (f1-f8) were prepared by factorial design (23) by taking three factors i.e. the concentration of: dr...

Various tannin-complexing agents have been used to study the potential adverse effects of tannins on rumen metabolism. Using a method based on turbidity formation, the binding of various tannin-complexing agents (polyvinyl polypyrrolidone (PVPP), polyethylene glycol (PEG) of molecular weights 2000 to 35,000, and polyvinyl pyrrolidone (PVP) of molecular weight 10,000, 40,000 and 360,000) to tann...

Purpose Crops are increasingly affected by drought; hence, the current study explored potential role of three desert endophytic fungi, Aspergillus fumigatus , terreus and Talaromyces variabilis in conferring drought tolerance tomato plants. Design/methodology/approach Preserved fungi from a Rhazya stricta plant were adopted to obtain required fungal treatment; tomatoes received treatments direc...

The bioavailability of sulindac (SDC), a nonsteroidal anti-inflammatory drug, is low due to poor aqueous solubility and poor dissolution rate. For this reason it is necessary to enhance the solubility and enhance dissolution of the drug by dispersing SDC in polyethylene glycols 6000 (PEG 6000) and polyvinyl pyrrolidone 40000 (PVP 40000) matrices using the coevaporation technique. Studying the i...

Amaç: Bu çalışma, domates genetik kaynaklarının kuraklık stresine karşı hızlı taranması için PEG-6000'in neden olduğu stresinin uygunluğunu belirlemek amacıyla yapılmıştır. Materyal ve Yöntem: Çalışmada, kurağa toleransı yüksek (M28) düşük (Alyans) bilinen iki çeşit test edilmiştir. Çimlendirme testinde farklı PEG konsantrasyonu (%4 %6) denenmiştir. Fide aşamasındaki su kültürü tekniği ile gerç...

Four methods of extraction and three methods of concentration of three enteric viruses from mussels were comparatively evaluated by reverse transcriptase PCR (RT-PCR). Shellfish were experimentally contaminated by immersion in seawater seeded with astrovirus, hepatitis A virus, or poliovirus. Sixty-gram samples of mussel tissues were processed by using borate buffer, glycine solution, saline be...

growing applications of phenylalanine dehydrogenase (phedh) enzyme in the medical and pharmaceutical industries encourages researchers to seek simple, fast and economical alternative purification methods. with goal of finding a new technique, the extraction and purification of recombinant bacillus badius phedh in polyethylene glycol 6000 (peg-6000) and ammonium sulfate aqueous two-phase systems...
