Rabbit Anti-Human GDA Polyclonal antibody

Domain Adaptation aims at utilizing source data to establish an exact model for a related but different target domain. In recent years, many effective models have been proposed to propagate label information across domains. However, these models rely on large-scale labeled data in source domain and cannot handle the case where the source domain lacks label information. In this paper, we put forward a Graph Regularized Domain Adaptation (GDA) to tackle this problem. Specifically, the proposed GDA integrates graph regularization with maximum mean discrepancy (MMD). Hence GDA enables sufficient unlabeled source data to facilitate knowledge transfer by utilizing the geometric property of source domain, simultaneously, due to the embedding of MMD, GDA can reduce source and target distribution divergency to learn a generalized classifier. Experimental results validate that our GDA outperforms the traditional algorithms when there are few labeled source samples.

To study the effectiveness of prophylactic embolization of hepaticoenteric arteries to prevent gastrointestinal complications during radioembolization. A PubMed, Embase and Cochrane literature search was performed. We included studies assessing both a group of patients with and without embolization. Our search revealed 1401 articles of which title and abstract were screened. Finally, eight studies were included investigating 1237 patients. Of these patients, 456 received embolization of one or more arteries. No difference was seen in the incidence of gastrointestinal complications in patients with prophylactic embolization of the gastroduodenal artery (GDA), right gastric artery (RGA), cystic artery (CA) or hepatic falciform artery (HFA) compared to patients without embolization. Few complications were reported when microspheres were injected distal to the origin of these arteries or when reversed flow of the GDA was present. A high risk of confounding by indication was present because of the non-randomized nature of the included studies. It is advisable to restrict embolization to those hepaticoenteric arteries that originate distally or close to the injection site of microspheres. There is no conclusive evidence that embolization of hepaticoenteric arteries influences the risk of complications.
