We examine the co-movement between exchange rate (EXR) returns and stock (STK) in Africa amid COVID-19 a time frequency domain. Therefore, we employ bi- partial wavelet multiple correlation techniques using daily data from 13 February 2013 to 6 May 2021. Our findings divulge that COVID-19’s effect does not increase intensity of relationship EXR STK but causes significant difference lead-lag two...

Imaging the expression of successful gene transduction has been demonstrated in vivo for the first time by using an appropriate combination of "marker gene" and "marker substrate" in an experimental animal model. The herpes simplex virus 1 thymidine kinase (HSV1-tk) gene was selected as an example of a marker gene, and the recombinant STK retrovirus containing HSV1-tk was used to transduce RG2 ...

Rupture of the anterior cruciate ligament (ACL) is a high incidence injury usually treated surgically. According to common knowledge, it does not heal spontaneously, although some claim the opposite. Regeneration therapy by Khalifa was developed for injuries of the musculoskeletal system by using specific pressure to the skin. This randomized, controlled, observer-blinded, multicentre study was...

Streptococcus suis serotype 2 (SS2) is an important swine and human pathogen responsible for septicemia and meningitis. The bacterial homologues of eukaryotic-type serine/threonine kinases (ESTKs) have been reported to play critical roles in various cellular processes. To investigate the role of STK in SS2, an isogenic stk mutant strain (Δstk) and a complemented strain (CΔstk) were constructed....

MADS-box genes encode transcriptional regulators that are critical for flowering, flower organogenesis and plant development. Although there are extensive reports on genes involved in flower organogenesis in model and economically important plant species, there are few reports on MADS-box genes in woody plants. In this study, we have cloned and characterized AGAMOUS (AG), SEEDSTICK (STK) and SE...

BA-Stk1 is a serine/threonine kinase (STK) expressed by Bacillus anthracis. In previous studies, we found that BA-Stk1 activity is modulated through dephosphorylation by a partner phosphatase, BA-Stp1. In this study, we identified critical phosphorylation regions of BA-Stk1 and determined the contributions of these phosphodomains to autophosphorylation and substrate phosphorylation. The data in...
