Cytokinins control critical aspects of plant development and environmental responses. Perception of cytokinin ultimately leads to the activation of proteins belonging to the type-B Response Regulator family of cytokinin response activators. In Arabidopsis thaliana, ARR1 is one of the most abundantly expressed type-B Response Regulators. We investigated the link between cytokinin signaling, protein synthesis, plant growth, and osmotic stress tolerance. We show that the increased cytokinin signaling in ARR1 gain-of-function transgenic lines is associated with increased protein synthesis rates which leads to growth inhibition and hypersensitivity to osmotic stress. Cytokinin-induced growth inhibition and osmotic stress hypersensitivity were rescued by treatments with abscisic acid, a hormone known to inhibit protein synthesis. We also demonstrate that cytokinin-induced protein synthesis requires isoforms of the ribosomal protein L4 encoded by the cytokinin-inducible genes RPL4A and RPL4D, and that RPL4 loss of function increases osmotic stress tolerance and decreases sensitivity to cytokinin-induced growth inhibition. These findings reveal that an increase in protein synthesis negatively impacts growth and osmotic stress tolerance and explain some of the adverse effects of elevated cytokinin action on plant development and stress physiology.

METHODS An exploratory, descriptive, qualitative design using a purposive sampling technique was employed. Overall, 12 women and six men participated in the study. In-depth interviews were conducted using a semi-structured interview guide. The Braun and Clarke (2006) procedure for data analysis was followed. Data collection spanned 9 months (January to October 2017). RESULTS Five major challenges were identified that were commonly experienced by our participants at every phase of the ART treatment, including the high cost of ART treatment, the long distance to treatment centers, drug treatment challenges, disturbances in daily routine and work, and anxiety about pregnancy outcome. CONCLUSION Given the emotional and psychological challenges reported by the participants in the present study, an integration of counseling units in the ART centers is recommended, manned by qualified personnel such as clinical psychologists and counselors to support clients at every stage of the treatment. Also, given the high cost of ART services, as reflected in the participants' views, it is recommended that private health insurance companies fund some aspect of ART services, such as laboratory investigations and medications.

In lowland Hawai'i, bird communities are composed of primarily introduced species, with scattered populations of abundant native species. We examined the influence of avian host community composition-specifically the role of native and introduced species, as well as host diversity, on the prevalence of avian malaria (Plasmodium relictum) in the southern house mosquito (Culex quinquefasciatus). We also explored the reciprocal effect of malaria transmission on native host populations. Avian malaria infection prevalence in mosquitoes increased with the density and relative abundance of native birds, as well as host community competence, but was uncorrelated with host diversity. Avian malaria transmission was estimated to reduce population growth rates of Hawai'i 'amakihi (Chlorodrepanis vires question in other systems to determine the generality of this result.

Given histotype-specific prospective controlled data lacking, this study retrospectively evaluated doxorubicin plus dacarbazine, doxorubicin plus ifosfamide, and doxorubicin alone as first-line treatments for advanced/metastatic leiomyosarcoma treated at European Organization for Research and Treatment of Cancer Soft Tissue and Bone Sarcoma Group (EORTC-STBSG) sites. METHODS The inclusion criteria were a confirmed histological diagnosis, treatment between January 2010 and December 2015, measurable disease (Response Evaluation Criteria in Solid Tumors 1.1), an Eastern Cooperative Oncology Group performance status ≤2, and an age ≥ 18 years. The endpoints were progression-free survival (PFS), overall survival (OS), and overall response rate (ORR). PFS was analyzed with methods for interval-censored data. Patients were matched according to their propensity scores, which were estimated with a logistic regression model accounting for his0.40-1.06) and doxorubicin (median, 30.3 months; 95% CI, 21.0-36.3 months; HR, 0.66; 95% CI, 0.43-0.99). Adjusted analyses retained an effect for PFS but not for OS. None of the factors selected for multivariate analysis had a significant interaction with the received treatment for both PFS and OS. CONCLUSIONS This is the largest retrospective study of first-line treatment for advanced leiomyosarcoma. In the propensity score-matched population, doxorubicin and dacarbazine showed favorable activity in terms of both ORR and PFS and warrants further evaluation in prospective trials. © 2020 American Cancer Society.Immunotherapeutic modalities are currently revolutionizing cancer treatment. In pancreatic cancer, however, early clinical trials have been disappointing. The optimization of immunotherapeutic strategies requires better understanding of the inflammatory tumor microenvironment. Therefore, the aim of our study was to perform a detailed in situ description of lymphocyte infiltration patterns in resected pancreatic and other periampullary cancers. Multiplexed immunofluorescence imaging was applied to tissue microarrays with tumors from a cohort of 175 patients with resected periampullary adenocarcinoma. A panel of immune cell markers including CD4, CD8α, FoxP3, CD20, CD45RO and pan-cytokeratin was applied to allow for simultaneous spatial analysis of multiple lymphocyte populations. The majority of lymphocyte populations were significantly more abundant in intestinal (I-type) compared to pancreatobiliary (PB-type) tumors. Hierarchical cluster analysis revealed several immune cell signatures of potential clinical relevance.
