Safety of long-term anticoagulation in patients with brain metastases.

Anticoagulation is thought to be associated with the risk of intracranial hemorrhage (ICH) in patients with brain metastases; however, the data on this topic are limited. This study was conducted to determine the incidence of ICH associated with anticoagulant use in adult patients with brain metastases. Consecutive patients with brain metastases occurring from 2006 to 2014 were identified from a single-institution database.

Therapy-related myeloid neoplasms after autologous hematopoietic stem cell transplantation in lymphoma patients.

Lymphoma patients treated with autologous transplantation (ASCT) live an increasingly long life with the recent advancement in therapeutic modalities. This has resulted in an increase in the incidence of therapy-related myeloid neoplasms (t-MN), which is one of the leading causes of non-relapse mortality. Several observational studies have linked the development of t-MN after ASCT with the intensity and frequency of chemotherapy, particularly alkylating agents, use of total body irradiation (TBI), and peripheral blood progenitor cells.

Soybean homologs of MPK4 negatively regulate defense responses and positively regulate growth and development.

Mitogen-activated protein kinase (MAPK) cascades play important roles in disease resistance in model plant species such as Arabidopsis (Arabidopsis thaliana) and tobacco (Nicotiana tabacum). However, the importance of MAPK signaling pathways in the disease resistance of crops is still largely uninvestigated. To better understand the role of MAPK signaling pathways in disease resistance in soybean (Glycine max), 13, nine, and 10 genes encoding distinct MAPKs, MAPKKs, and MAPKKKs, respectively, were silenced using virus-induced gene silencing mediated by Bean pod mottle virus.

Functional analysis of the Asian soybean rust resistance pathway mediated by Rpp2.

Asian soybean rust is an aggressive foliar disease caused by the obligate biotrophic fungus Phakopsora pachyrhizi. On susceptible plants, the pathogen penetrates and colonizes leaf tissue, resulting in the formation of necrotic lesions and the development of numerous uredinia. The soybean Rpp2 gene confers resistance to specific isolates of P.
