Cardiovascular Regulation By Kvβ1.1 Subunit, Jared Tur

USF Tampa Graduate Theses and Dissertations

Heterologous expression systems such as COS-7 cells have demonstrated the profound effects of KCNAB1-3 or Kvβ1-3 proteins on voltage gated potassium channels (Kv) channels. Indeed, in the presence of these β-subunits transiently expressed Kv channels are often modulated in multiple ways. Kv channel membrane expression is often increased in the presence of β-subunits. In addition, non-inactivating Kv currents suddenly become fast-inactivating and fast-inactivating channels become even faster. While much research has demonstrated the profound effects the β-subunits in particular the Kvβ1 subunit have on transiently expressed Kv currents little to date is known of the physiological role it may play. …

Cloning Of The Gene, Purification As Recombinant Protein And Functional Characterization Of Leishmania Mexicana Cytochrome B5 Reductase, Ala Azhari

Leishmania are protozoan parasites that are transmitted by a sand fly vector. These parasites affect not only humans but also wild animals including domestic dogs and rodents, which form an additional challenge and public health problem to control the disease. Leishmaniasis is an important disease with worldwide distribution, including Saudi Arabia, the Middle East, and other tropical and subtropical areas around the world. Due to the expansion of irrigation and agricultural activities, more exposure to sand fly occurs, which leads to the expansion of leishmaniasis infections as newly emerging disease.

Emerging drug resistance in leishmaniasis is an additional problem, contributed …
