Development of High-Strength Extended-Release Multiparticulate System by Crystallo-co-agglomeration Technique with Integration of Central Composite Design. AAPS PharmSciTech. 2019 May 21;20(5):192 Authors: Gaikwad VL, Jadhav NR, Pawar AP, Mahadik KR Abstract The number of unit operations to be followed in the preparation of tablets was cumbersome and may introduce material as well as process-related critical parameters which may negatively affect the quality of final formulation. The hypothesis of the present research was to develop directly compressible, high-strength extended-release spherical agglomerates of talc containing indapamide by crystallo-co-agglomeration technique. Hydroxypropyl methylcellulose 15 cps and polyethylene glycol 6000 were used to impart the desired sphericity, strength, and deformability to agglomerates, respectively. Ethyl cellulose 10 cps was used to improve the strength of agglomerates and achieve extended release. Design of experiment (rotatable central composite design) was implemented for the elucidation of the effect of type and quantity of polymers on quality attributes of agglomerates. Prepared agglomerates were evaluated for morphological, micromeritic, mechanical, and drug release properties. A satisfactory yield (> 97%, wt/wt), better crushing strength, and low friability of agglomerates indicated good processing and handling characteristics. Compatibility and reduced crystallinity of indapamide i...
Conclusions: Our report is the first study to examine the distant metastatic breast cancer proteome using FFPE tissues. The depth of our dataset allowed us to discover a novel biomarker candidate and a proteomic characteristics of distant metastatic breast cancer. Distinct molecular features of various breast cancer subtypes were also established. Our proteomic data constitute a valuable resource for research on distant metastatic breast cancer.

This article summarizes some clinical shortcuts. Simple procedures such as taking a detailed medical history can provide clues to the underlying cause of chronic pruritus in order to achieve targeted diagnostic workup or to avoid unnecessary testing. If clinical shortcuts are not identified, we recommend a structured medical history, which is also discussed in this article. PMID: 32488462 [PubMed - as supplied by publisher]
