Duration of peripheral nerve blocks depends on multiple factors. Both technique and type of local anesthetic used, either with or without adjuncts, may result in different duration times of the block. The purpose of the present study was to compare the duration of postoperative analgesia of 30 mL ropivacaine 0.75 % with or without epinephrine for popliteal sciatic nerve block.

Continuous epidural infusions are commonly used in clinical settings to reduce the likelihood of transition to postherpetic neuralgia via pain control. The purpose of this study was to compare the efficacy of conventional continuous epidural infusion to that of continuous epidural infusion in which the catheter is guided by electric stimulation to areas with neurological damage for the treatment of zoster-related pain and prevention of postherpetic neuralgia.

Pain control after hepatectomy is usually achieved by opioids. There are signifcant individual differences in the amount of opioids used after hepatectomy, and the metabolism of opioids is liver-dependent. The purpose of our study was to explore the possible risk factors for opioid consumption during the frst 48h after surgery.

The purpose of this study was to examine whether the administration of nickel (Ni) was associated with cell apoptosis and also to evaluate whether post acute oral exposure to hyperoside would cause histopathologic alterations in rats. Four groups of male SpragueDawley rats (n = 7) used in this study were as follows: a control group and groups treated with Ni (as NiCI2, 13 mg/kg), hyperoside (Hyp) (50 mg/kg), and Ni + Hyp.

Propofol, a widely used sedative in endoscopic procedures, sometimes causes cardiopulmonary complications. Intravenous lidocaine can diminish visceral pain and decrease the dose of propofol. The purpose of this study was to assess the efficacy and safety of intravenous lidocaine in reducing propofol dosage during paediatric colonoscopy.

The existence of cation-vacancy sites in fullerides might lead to long-range ordering and generate a new vacancy-ordered superstructure. The purpose of this work is to search whether or not long-range ordering of vacant tetrahedral sites, namely superstructure emerges in nonstoichiometric K1.5Ba0.25CsC60 fulleride. Therefore, K1.5Ba0.25CsC60 with cation-vacancy sites is synthesized using a precursor method to avoid inadequate stoichiometry control and formation of impurity phases within the target composition.

Phenolics are secondary metabolites known as the natural antioxidants. They play significant role in plant defence against the pathogens, therefore used as treatment and to control the pathogenic infections in human also. Turmeric is well-known and valued medicinal plant due to the presence of natural occurring secondary metabolite. The present study aimed to evaluate the total phenolics and curcumin content from the leaves and rhizomes of turmeric germplasms. For this purpose, 30 turmeric germplasm with diverse background were used.

In this study, we aimed to use ferrate as an all-in-one alternative for the removal of chlorine-consumed compositions such as organic, color, turbidity, iron, and manganese in river water for water supply purposes. Ferrate (FeO42-) was simultaneously employed as coagulant and oxidant for purification of Saigon River water in order to reduce the formation of disinfection byproducts in the produced tap water.

The purpose of study is extraction and isolation of hippadine from the bulbs of Crinum latifolium for using as a reference standard for quality control of herbs and hippadine-containing preparations. Bulbs powder of Crinum latifolium was percolated with 70% ethanol, percolate obtained was evaporated at 65 0C to give a liquid extract. The extract was fractionated by distribution with n-hexane. The n-hexane extract was then chromatographed on silicagel 60 (0.04 - 0.063 mm). Hippadine was isolated, purified and elucidated by NMR, MS, IR and UV-Vis spectrum.
