Hyperuricemia is the condition of excessive presence of plasma uric acid ≥ 6 mg/dl. Conventional clinical/hospital urate-lowering treatment includes the administration of non-steroid anti-inflammatory drugs or xanthine oxidase inhibitors. Numerous drawbacks can be observed from these conventional treatments. In patients with refractory gout symptoms and tumor lysis syndrome, recombinant uricase...
The contributions of Palestinian women have historically been discredited and delegitimized. This has occurred both due to societal patriarchy, and due to patriarchal norms being exacerbated by the conditions of living under the violent Israeli occupation and settler colonialism. Yet in actuality, Palestinian women have played many diverse roles in...
Genetic sampling is used in many wildlife fields to gather data on populations or individuals. In noninvasive genetic sampling, animals do not need to be captured. DNA can be gathered from hair, scat, or other residue shed into the environment. However, this can result in degraded DNA, so it is...
