Cddo-Me Attenuates Fibroblast And Macrophage Activation In Limited Cutaneous Systemic Sclerosis, Heetaek Yang, Emily A. Morris, Chen-Yu Wang, Nicole M. Orzechowski, Michael Whitfield, Patricia Pioli

Dartmouth College Master’s Theses

Abstract

Systemic Sclerosis (SSc) is a rare autoimmune disease characterized by multiple-organ involvement and notably by fibrosis. Current therapies for SSc focus on symptom managements and treating specific organ related complications. However, heterogeneous nature of the disease further complicates treatment responses and hinders the development of new therapies. Therefore, there is a critical unmet need for the development of patient-specific therapeutics.

The objectives of this thesis were: (1) to evaluate the therapeutic potential of Bardoxolone Methyl (CDDO-Me) in both SSc fibroblasts and SSc macrophages. To achieve these goals, I utilized both wet-lab analysis tools and computational analysis.

A Review Of Lithium-Ion Battery Capacity Fade Deceleration At Power Fluctuations In Renewable Energy Systems, Isaac Gwayi

Tanzania Journal of Engineering and Technology (TJET)

Application of lithium-ion (Li-ion) batteries to store energy in renewable energy systems (RESs) is increasing due to their promising properties. Therefore, it is crucial to understand aging behaviours of Li-ion battery during RES life time as this directly affects cost of energy. Li-ion battery aging can be categorised into calendar aging and cycle aging. Calendar aging depends mainly on temperature and state of charge (SoC). In addition to temperature and SoC, cycle aging depends also on charge and discharge current rates and cut-off voltages. Higher current rates lead to faster Li-ion battery aging. It is necessary to identify appropriate battery …
