During the dissolution of cocrystal particles, solution-mediated phase transformation (SMPT) can occur either on particle surface (PS-SMPT) or in bulk solution (BP-SMPT). In this study, we compared effect various polymers PS-SMPT and BP-SMPT for first time using carbamazepine saccharine (CBZ-SAC) as a model drug. Polyethylene glycol 6000 (PEG), polyvinylpyrrolidone K-30 (PVP), hydroxypropyl met...
Background and purpose: One of the methods of preparing controlled-release dosage forms is the incorporation of drug in a matrix containing a hydrophilic rate-controlling polymer. Drug-polymer ratio, drug particle size and HPMC particle size have been identified as modifiers of drug release. This study evaluated the relationship and influence of formulation factors such as drug-HPMC ratio and p...
Antimicrobial activity and the properties of edible film were studied by incorporating with encapsulated clove (Eugenia caryophyllata Thunb.) oil as a natural antibacterial agent. The minimal bactericidal concentration (MBC) of clove oil inhibited the growth of E. coli O175:H7, S. aureus and L. monocytogenes were tested in the stationary phase. The results showed that 1.0, 1.5 and 0.5% of clove...
A solid biopolymer electrolytes (BEs) based on hydroxypropyl methylcellulose (HPMC) doped with different concentrations of ceric ammonium nitrate (NH4)2Ce(NO3)6 (CAN) were prepared by solution cast method. Different techniques has been employed to investigate the effects of structural, thermal and ionic conductivity behavior of these polymer electrolyte films upon gamma irradiation with differe...
در سال های اخیر هیدروژل های تزریقی حساس به دما در دارورسانی و دیگر کاربردهای زیست پزشکی به طور گسترده ای مورد توجه قرار گرفته اند. در این پژوهش، از هیدروژل حساس به دمای کیتوسان/گلیسرول فسفات به عنوان حاملی برای ریزذرات hpmc حاوی داروی ونکومایسین هیدروکلراید استفاده شده است. ریزذرات hpmc با هدف رسیدن به اندازه ذرات کوچک و شکل سطحی مناسب، با استفاده از دستگاه خشک کن پاششی تهیه شدند. ریزذرات تهیه ...
PURPOSE Propofol is a popular i.v. anesthetic induction drug that causes pain when given i.v., the incidence of which is between 28%-90%. We plan to determine the optimal dose of ketamine in the prevention of propofol injection pain and compare it with lidocaine, the commonly proposed pre-treatment. METHODS In a double-blind randomized study 500 Patients (ASA I, II) scheduled for elective str...
Glycolytic enzyme phosphoglycerate mutase (PGAM) plays an important role in coordinating energy production with generation of reducing power and the biosynthesis of nucleotide precursors and amino acids. Inhibition of PGAM by small RNAi or small molecule attenuates cell proliferation and tumor growth. PGAM activity is commonly upregulated in tumor cells, but how PGAM activity is regulated in vi...
یکی از انواع محصولات نانوایی که متقاضیان خاص خود را دارد محصولات فاقد گلوتن است که خاص افراد مبتلا به سیلیاک می باشد. این افراد به دلیل بروز حساسیت شدید نسبت به گلوتن، می بایست تا پایان عمر از مصرف غذا های حاوی گلوتن خودداری کنند. در کشور های پیشرفته انواع محصولات نانوایی جهت استفاده این افراد تهیه و به بازار عرضه می گردد. این در حالی است که چنین بیمارانی در کشور ما حتی در تهیه نان نیز با مشکل ...
Bu araştırmada, serada yetiştirilen hıyar bitkisinin yarı ıslatmalı sulama (YIS) ve geleneksel kısıntılı sulamaya (KS) tepkisinin belirlenmesi amaçlanmıştır. Çalışma, Türkiye’nin güneyinde Antalya koşullarında plastik örtülü cam olmak üzere iki farklı yürütülmüştür. Kontrol konu (K100) ile birlikte (KS75 KS50), ardışık-yarı (A-YIS75 A-YIS50) sabit-yarı (S-YIS75 S-YIS50) yedi konusu ele alınmışt...
The results of the experiments conducted on a high land belonging to Salna Series under Madhupur Tract (Shallow Red Brown Terrace Soil) with different rates N, P, K, S, B and Mo cow dung organic compost evince that application N120 P120 K100 S20 B1 Mo0.20OC0.5 (T16) had best effect growth yield cauliflower followed P180 Mo0 2CD10 (T7).
