The Ergh-al-Nassa pill (Hab) is a traditional combination suggested as one of the most effective preparations useful for treatment of sciatica. Although traditional preparations can be applied as new therapeutic drugs for investigations and clinical trials, they need to be reformulated to achieve pharmacopoeial standards for modern medicine. In this research, based on seven traditional Persian pharmacopeias for Ergh-al-NassaHab, nine different molded tablets were reformulated. Each formulation comprised the same amount of colchicum, ginger, aloe and yellow myrobalan fruit.

Traditionally, thick enamel has often been used to infer durophagy (i.e., hard nut and seed consumption) in extinct hominins. These inferences are based on the hypothesis that thick enamel is primarily an adaptation to prevent tooth fracture or chipping resulting from high-stress loads produced during the mastication of large hard foods. An alternative view argues that thick enamel may aid in maintaining tooth function in the face of gradual dental wear from grit, phytoliths and acid, which may be found in foods of widely varying hardness.

The direct quantitation of active ingredients in solid pharmaceutical tablets by desorption electrospray ionization mass spectrometry (DESI MS) is complicated by the dependence of the DESI signal on variables such as spray angles and distances, morphological sample properties, and the difficulty of properly incorporating an internal standard. Here, a DESI MS method for the direct quantitative screening of widely counterfeited antimalarial tablets containing artesunate is presented.

The purpose of this research was to mask the intensely bitter taste of artemether (ARM) and to formulate a rapid-disintegrating tablet (RDT) of the taste-masked drug. Taste masking was done by solid dispersion with mono amino glycyrrhyzinate pentahydrate (GLY) by solvent evaporation method. To characterize and formulate taste masked rapid disintegrating tablets (RDTs) of ARM, the 1:1M solid dispersion was selected based on bitterness score.

Artesunate (ART) is widely used for the treatment of malaria, but the mechanisms of its effects on parasitized red blood cells (RBCs) are not fully understood. We investigated ART's influence on the dynamic deformability of ring-stage Plasmodium falciparum infected red blood cells (iRBCs) in order to elucidate its role in cellular mechanobiology. The dynamic deformability of RBCs was measured by passing them through a microfluidic device with repeated bottleneck structures. The quasi-static deformability measurement was performed using micropipette aspiration.
