Date palm () plays a vital role in ethnomedicinal practices in several parts of the world. There are over 2000 cultivars of date palm that differ in chemical composition and extent of bioactivity. The present study was undertaken to comparatively evaluate the antioxidant potential of three cultivars of date palm (Ajwah, Safawy and Sukkari) from Saudi Arabia and analyze their phenolic constituents in order to draw a rationale for their activity.

Objective: Quantitative documentation of the effects of outbreaks, including the coronavirus disease 2019 (COVID-19) pandemic, is limited in neurosurgery. Our study aimed to evaluate the effects of the COVID-19 pandemic on neurosurgical practice and to determine whether surgical procedures are associated with increased morbidity and mortality.

Methods: A multicenter case-control study was conducted, involving patients who underwent neurosurgical intervention in the Kingdom of Saudi Arabia during 2 periods: pre-COVID-19 and during the COVID-19 pandemic.

In addition to the rich nutritional value, date palm is also used in various ethnobotanical practices for the treatment of various disease conditions. Present investigation was undertaken to examine the neuropharmacological and antinociceptive effect of the ethanol extract of three date cultivars growing in Saudi Arabia, namely Ajwah, Safawy and Sukkari. Neuropharmacological effect was observed by pentobarbitone induced sleeping time, open field, and hole board test.

Background: Nanostructured lipid carriers (NLCs), composed of solid and liquid lipids, and surfactants are potentially good colloidal drug carriers. Thymoquinone is the main bioactive compound of Nigella sativa. In this study, the preparation, gastroprotective effects, and pharmacokinetic (PK) properties of thymoquinone (TQ)-loaded NLCs (TQNLCs) were evaluated.

Background: Intraoperative angiography is useful in evaluating the vascular lesion before clipping/excision, presence of any residual lesion, and excluding unintended occlusion/stenosis of the arterial branch/parent artery. The previously reported techniques using the superficial temporal artery involved either retrograde cannulation of the aortic arch or its permanent obliteration at the end of the procedure. The present report describes a simple method that enables cannulation of the artery using standard Sildenger's technique and ensures its patency at the end of the procedure for possible use in present or future procedures.
