The impact of particle size of nanostructured lipid carriers on follicular drug delivery: A comprehensive analysis of mouse and human hair follicle penetration.

Introduction: Follicular delivery is one of the targeted drug delivery methods aiming to target the hair follicles. The accumulation and retention time of targeted drugs is enhanced when nanoparticles are used as drug carriers. Particle size is one of the important factors affecting the penetration and accumulation of particles in the hair follicles, and there is a controversy in different studies for the best particle size for follicular delivery.

Comparing the efficacy of N-acetylcysteine plus carvedilol versus carvedilol in the prevention of atrial fibrillation following coronary artery bypass graft surgery.

Background: Atrial fibrillation (AF) is the most common arrhythmia following open-heart surgery. Agents with antioxidant properties may reduce postoperative complications like postoperative AF (POAF) in patients undergoing open-heart surgery. This study was conducted to assess the effect of N-acetylcysteine (NAC) in prevention of AF following coronary artery bypass graft (CABG) surgery.

Novel coronavirus disease 2019: predicting prognosis with a computed tomography-based disease severity score and clinical laboratory data.

Introduction: Currently, there are known contributing factors but no comprehensive methods for predicting the mortality risk or intensive care unit (ICU) admission in patients with novel coronavirus disease 2019 (COVID‑19).

Objectives: The aim of this study was to explore risk factors for mortality and ICU admission in patients with COVID‑19, using computed tomography (CT) combined with clinical laboratory data.

Patients And Methods: Patients with polymerase chain reaction-confirmed COVID‑19 (n = 63) from university hospitals in Tehran, Iran, were included.

Nanoethosomal formulation of gammaoryzanol for skin-aging protection and wrinkle improvement: a histopathological study.

Background: Free radical scavengers and antioxidants, with the main focus on enhanced targeting to the skin layers, can provide protection against skin ageing.

Objective: The aim of the present study was to prepare nanoethosomal formulation of gammaoryzanol (GO), a water insoluble antioxidant, for its dermal delivery to prevent skin aging.

Methods: Nanoethosomal formulation was prepared by a modified ethanol injection method and characterized by using laser light scattering, scanning electronic microscope (SEM) and X-ray diffraction (XRD) techniques.

Late Pleistocene human remains from Wezmeh Cave, western Iran.

Paleontological analysis of remains from Wezmeh Cave in western Iran have yielded a Holocene Chalcolithic archeological assemblage, a rich Late Pleistocene carnivore faunal assemblage, and an isolated unerupted human maxillary premolar (P(3) or possibly P(4)). Species representation and U-series dating of faunal teeth place the carnivore assemblage during oxygen isotope stages (OIS) 3 and 2, and noninvasive gamma spectrometry dating of the human premolar places it at least as old as early OIS 2. The human premolar crown morphology is not diagnostic of late archaic versus early modern human affinities, but its buccolingual diameter places it at the upper limits of Late Pleistocene human P(3) and P(4) dimensions and separate from a terminal Pleistocene regional sample.
