Chromatographic separation was carried out on a Hypurity C18 column (50 mm x 4.6 mm, 5 mu m) with an isocratic mobile phase and a total run time of 2.0 min only. The MRM of ENP and Alvocidib supplier ENPT is 377.10 ? 234.20 and 349.20 ? 206.10 respectively. The standard calibration curves showed excellent linearity within the range of 0.064 to 431.806 ng/mL for ENA and 0.064 to 431.720 ng/mL for ENPT (r

= 0.990). This is the only method which can quantitate upto 0.064 ng/mL for both ENP and ENPT in a single run with the shortest analysis time. In matrix effect experiment, this method shows a % CV (% coefficients of variation) of less than 5, which means that the proposed method is free from any kind of irregular ionization process.\n\nThis method was successfully applied to a pharmacokinetic study after oral administration of enalaprilmaleate 20mg tablet in Indian healthy male volunteers.

“Objective: The aim of the present study is to identify the facial nerve dissection technique routinely used during parotidectomy for benign parotid tumors

by Nigerian Oral and Maxillofacial (OMF) and Ear, Nose, and Throat (ENT) Surgeons.\n\nMaterials and Methods: A questionnaire-based study was conducted among Oral and Maxillofacial and Ear, Nose, and Throat Surgeons in Nigeria, on their experience with antegrade and retrograde facial nerve dissection techniques in parotid surgery. The respondents were asked to indicate their choice of dissection techniques in revision parotidectomy, limited superficial parotidectomy, Pevonedistat cost and in obese patients with large PCI-32765 mouse tumors. They were also asked to indicate if they routinely used perioperative facial nerve monitoring devices in parotid surgery for benign tumors.\n\nResult: About half (47.5%) of them routinely

used the antegrade technique, while only a few (12.5%) used the retrograde technique. A large number of them (40%), however, used a combination of antegrade and retrograde routinely. Technical ease was the main reason for the choice of technique. The antegrade technique was the technique of choice by most respondents for revision parotidectomy (60%) and limited superficial parotidectomy (62%). However, the retrograde approach was the technique of choice by most of them (47%) in case of parotidectomy in obese patients with large tumors. The routine use of perioperative facial nerve monitoring devices is an uncommon practice among OMF and ENT surgeons in Nigeria.\n\nConclusions: The antegrade approach for facial nerve dissection is the most common technique used in parotid surgery by Nigerian OMF and ENT surgeons. Nigerian surgeons need to consider the retrograde approach in selected cases of parotid surgery especially for localized tumors that are amenable to limited superficial parotidectomy. Inclusion of perioperative facial nerve monitoring devices is also advocated.
