I am Cuba-Soy Cuba: Commemorating 100 years of Russian Revolution

I am Cuba Soy Cuba is a 1964 Soviet Cuban film directed by Mikhail Kalatozov Hidden away in the Soviet archives for three decades, I Am Cuba is a wild celebration of Communist kitsch, mixing Slavic solemnity with Latin sensuality — a whirling, feverish dance through both the sensuous decadence of pre-revolutionary Havana and the grinding poverty and oppression of the Cuban people. In four stories of the revolution, the camera takes the viewer on a rapturous roller-coaster ride of bathing beauties, landless peasants, fascist police, and student revolutionaries.https://digitalcommons.fiu.edu/cri_events/1370/thumbnail.jp

Identification of 12 new susceptibility loci for different histotypes of epithelial ovarian cancer.

To identify common alleles associated with different histotypes of epithelial ovarian cancer (EOC), we pooled data from multiple genome-wide genotyping projects totaling 25,509 EOC cases and 40,941 controls. We identified nine new susceptibility loci for different EOC histotypes: six for serous EOC histotypes (3q28, 4q32.3, 8q21.11, 10q24.33, 18q11.2 and 22q12.1), two for mucinous EOC (3q22.3 and 9q31.1) and one for endometrioid EOC (5q12.3). We then performed meta-analysis on the results for high-grade serous ovarian cancer with the results from analysis of 31,448 BRCA1 and BRCA2 mutation carriers, including 3,887 mutation carriers with EOC. This identified three additional susceptibility loci at 2q13, 8q24.1 and 12q24.31. Integrated analyses of genes and regulatory biofeatures at each locus predicted candidate susceptibility genes, including OBFC1, a new candidate susceptibility gene for low-grade and borderline serous EOC

Guidelines for the use and interpretation of assays for monitoring autophagy (4th edition)1.

In 2008, we published the first set of guidelines for standardizing research in autophagy. Since then, this topic has received increasing attention, and many scientists have entered the field. Our knowledge base and relevant new technologies have also been expanding. Thus, it is important to formulate on a regular basis updated guidelines for monitoring autophagy in different organisms. Despite numerous reviews, there continues to be confusion regarding acceptable methods to evaluate autophagy, especially in multicellular eukaryotes. Here, we present a set of guidelines for investigators to select and interpret methods to examine autophagy and related processes, and for reviewers to provide realistic and reasonable critiques of reports that are focused on these processes. These guidelines are not meant to be a dogmatic set of rules, because the appropriateness of any assay largely depends on the question being asked and the system being used. Moreover, no individual assay is perfect for every situation, calling for the use of multiple techniques to properly monitor autophagy in each experimental setting. Finally, several core components of the autophagy machinery have been implicated in distinct autophagic processes (canonical and noncanonical autophagy), implying that genetic approaches to block autophagy should rely on targeting two or more autophagy-related genes that ideally participate in distinct steps of the pathway. Along similar lines, because multiple proteins involved in autophagy also regulate other cellular pathways including apoptosis, not all of them can be used as a specific marker for bona fide autophagic responses. Here, we critically discuss current methods of assessing autophagy and the information they can, or cannot, provide. Our ultimate goal is to encourage intellectual and technical innovation in the field

Intimate Partner Violence and Women with Severe Mental Illnesses: Needs and Challenges from the Perspectives of Behavioral Health and Domestic Violence Service Providers

Women with severe mental illnesses face high rates of violence victimization, yet little is understood about the unique needs and challenges these women present to the domestic violence and behavioral health agencies that serve them. To help address this knowledge gap, focus groups were conducted with 28 staff members from local behavioral health and domestic violence service agencies. Results from this exploratory study suggest that women with severe mental illnesses who experience intimate partner violence face additional challenges that exacerbate behavioral health and domestic violence issues and put these women at greater risk for continued victimization. DV and behavioral health agency staff experience individual-, provider-, and system-level barriers to serving this high-risk, high-need population. Recommendations and implications for domestic violence and behavioral health providers are discussed

Phase 2 study of bosutinib, a Src inhibitor, in adults with recurrent glioblastoma

BACKGROUND: Tumor cell infiltration is a major mechanism of treatment escape in glioblastoma. Src is an intracellular tyrosine kinase that mediates tumor cell motility and invasiveness. We evaluated the efficacy and safety of bosutinib, a tyrosine kinase inhibitor that potently inhibits Src and Abl, in patients with recurrent glioblastoma. METHODS: In this two-arm study, patients with histologically confirmed recurrent glioblastoma and ≤ 2 relapses, not previously treated with anti-vascular endothelial growth factor therapy, were administered oral bosutinib 400 mg daily. Arm A planned for 6 patients who were candidates for surgical resection to be given bosutinib for 7-9 days prior to resection. Arm B was a two-stage design phase 2 trial targeting 30 patients. The primary endpoint was progression-free survival at 6 months (PFS6) in Arm B. RESULTS: After 9 patients enrolled onto stage 1 of Arm B, 9 (100%) patients progressed within 6 months. Therefore, the study met the pre-specified criteria for early closure and both Arms were closed. In Arm B, Median PFS was 7.71 weeks and median OS was 50 weeks. Best objective response was stable disease in one patient (11.1%). Seven patients (77.8%) had treatment-related AEs of any grade and 2 (22.2%) were grade ≥3. Arm A was closed after 2 patients enrolled. Src activation was evident in all archival tumor samples. CONCLUSION: Bosutinib monotherapy does not appear to be effective in recurrent glioblastoma. However, Src remains a potential target based on its upregulation in tumor samples and role in glioma invasion

Exposure to Ozone Modulates Human Airway Protease/Antiprotease Balance Contributing to Increased Influenza A Infection

Exposure to oxidant air pollution is associated with increased respiratory morbidities and susceptibility to infections. Ozone is a commonly encountered oxidant air pollutant, yet its effects on influenza infections in humans are not known. The greater Mexico City area was the primary site for the spring 2009 influenza A H1N1 pandemic, which also coincided with high levels of environmental ozone. Proteolytic cleavage of the viral membrane protein hemagglutinin (HA) is essential for influenza virus infectivity. Recent studies suggest that HA cleavage might be cell-associated and facilitated by the type II transmembrane serine proteases (TTSPs) human airway trypsin-like protease (HAT) and transmembrane protease, serine 2 (TMPRSS2), whose activities are regulated by antiproteases, such as secretory leukocyte protease inhibitor (SLPI). Based on these observations, we sought to determine how acute exposure to ozone may modulate cellular protease/antiprotease expression and function, and to define their roles in a viral infection. We utilized our in vitro model of differentiated human nasal epithelial cells (NECs) to determine the effects of ozone on influenza cleavage, entry, and replication. We show that ozone exposure disrupts the protease/antiprotease balance within the airway liquid. We also determined that functional forms of HAT, TMPRSS2, and SLPI are secreted from human airway epithelium, and acute exposure to ozone inversely alters their expression levels. We also show that addition of antioxidants significantly reduces virus replication through the induction of SLPI. In addition, we determined that ozone-induced cleavage of the viral HA protein is not cell-associated and that secreted endogenous proteases are sufficient to activate HA leading to a significant increase in viral replication. Our data indicate that pre-exposure to ozone disrupts the protease/antiprotease balance found in the human airway, leading to increased influenza susceptibility
