Secondary nucleation guided noncovalent synthesis of dendritic homochiral superstructures via growth on and from surface.

Secondary nucleation is an emerging approach for synthesizing higher-order supramolecular polymers with exciting topologies. However, a detailed understanding of growth processes and the synthesis of homochiral superstructures is yet to be demonstrated. Here, we report the non-covalent synthesis of dendritic homochiral superstructures using NIR triimide dyes as building blocks via a secondary nucleation elongation process.

Dealing with dichotomies in health care: Case reports.

Dichotomies with respect to medical orientations and public health have been common in the past and even in the present probably orchestrated by the traditional versus modern medical concepts that became eternal arena for disquiet in the healing world of many countries. In public health, the so-called technology tradition was especially dominant which assumed the power of technology and the paternalistic 'managerial mode' regarding disease control programs. Such a 'managerial perversion' has demolished the positivity of primary health care as well as the social determinants framework.

Integrating virtual reality to enhance remote teaching of anatomy during unprecedented times.

The COVID-19 pandemic necessitated a global paradigm shift in the teaching of human anatomy. Most institutions successfully transitioned from traditional in-person teaching methods, to various distance-learning strategies. Since virtual reality (VR) offers immersive three-dimensional (3D) experiences, this study investigated students' experiences regarding the capacity of VR to support distance-learning of anatomy.

Gelatin and lipidoid integrate to create to enhance siRNA delivery with low toxicity.

RNAi therapeutics possess the potential to cure many uncurable human diseases. For instance, RNAi therapeutics using liposomes showed remarkable survival benefits in patients with liver diseases. However, the extension of liposomes to deliver RNA to cure other ailments has largely been unsuccessful.
