Propolis obtained from bee hives is a natural substance with antimicrobial properties. It limited by its insolubility in aqueous solutions; hence ethanol and ethyl acetate extracts of Malaysian propolis were prepared. Both the displayed anti-biofilm properties against Enterococcus faecalis, common bacterium associated hospital-acquired infections. High performance liquid chromatography (HPLC) analysis revealed presence flavonoids like kaempferol pinocembrin. This study investigated role...

Staphylococcus epidermidis, is a common microflora of human body that can cause opportunistic infections associated with indwelling devices. It resistant to multiple antibiotics necessitating the need for naturally occurring antibacterial agents. Malaysian propolis, natural product obtained from beehives exhibits antimicrobial and antibiofilm properties. Chitosan-propolis nanoparticles (CPNP) were prepared using propolis tested their effect against S. epidermidis. The cationic depicted zeta...

To determine the antibacterial effect of propolis nanoparticles (PNs) as an endodontic irrigant against Enterococcus faecalis biofilm inside root canal system. Two-hundred-ten extracted human teeth were sectioned to obtain 6 mm middle third root. The was enlarged internal diameter 0.9 mm. specimens inoculated with E. for 21 days. Following this, randomly divided into seven groups, 30 dentinal blocks in each group including: I—saline; II—propolis 100 µg/mL; III—propolis 300 IV—propolis...

Abstract Background The successful outcome of endodontic treatment depends on controlling the intra-radicular microbial biofilm by effective instrumentation and disinfection using various irrigants intracanal medicaments. Instrumentation alone cannot effectively debride root canals specially due to complex morphology canal system. A number antibiotics surfactants are being widely used in biofilms however, current trend is towards identification natural products disinfection. aim study was...

Context: Kaempferol has a large particle size and poor water solubility, leading to oral bioavailability. The present work aimed develop kaempferol nanosuspension (KNS) improve pharmacokinetics absolute Methods: A was prepared using high pressure homogenization (HPH) techniques. physico-chemical properties of the were characterized photon correlation spectroscopy (PCS), transmission electron microscope (TEM), Fourier transform infrared (FTIR) x-ray diffractometry (XRD). reversephase...

Cesarean scar ectopic pregnancies (CSEP) are a rare type of pregnancy. This condition occurs when blastocyst is implanted in the left by previous cesarean section (C-section). CSEP can lead to risk maternal hemorrhage, which severe cases mortality. In recent decades, incidence has surged significantly, largely due increasing rate C-sections worldwide. Here, we present case 30-year-old third gravida, with C-section performed year ago, no living child. The patient presented delayed menstrual...

Purpose: To develop a simple, accurate, and precise high performance chromatography (HPLC) method with spectrophotometric detection for the determination of doxorubicin hydrochloride in rat plasma.Methods: Doxorubicin daunorubicin (internal standard, IS) were separated on C18 reversed-phase HPLC column. Following protein precipitation extraction, chromatographic separation was accomplished mobile phase consisting acetonitrile: water at ratio 30:70 (pH 3.0), drug detected 233 nm using UV...

Student perspectives of clinical preparedness have been studied in the literature, but viewpoint supervisors is limited. Hence, aim was to examine perspective on characteristics health professional students important for learning.This a descriptive, questionnaire-based, cross-sectional study conducted at three higher education institutions Malaysia. A previously published questionnaire with 62 adopted modifications after pre-testing. Descriptive analysis completed demographic data. The...
