OV treatment also prevented M2 polarization and reduced EV cargos from M2 TAMs. Finally, in vivo data demonstrated that OV treatment overcame CDDP resistance. OV only and the OV + CDDP combination both resulted in significant reductions in mTOR, β-catenin, CDK6, and miR-21 expression in tumor samples and EVs isolated from serum. Collectively, we demonstrated that M2 TAMs induced malignant properties in BCa cells, in part via oncogenic EVs. OV treatment prevented M2 TAM polarization, reduced EV cargos derived from M2 TAMs, and suppressed β-catenin/mTOR/CDK6 signaling. These findings provide preclinical evidence for OV as a single or adjuvant agent for treating drug-resistant BCa.Behavioral neuroendocrinology has a rich history of using diverse model organisms to elucidate general principles and evolution of hormone-brain-behavior relationships. The oxytocin and vasopressin systems have been studied in many species, revealing their role in regulating social behaviors. Oxytocin and vasopressin receptors show remarkable species and individual differences in distribution in the brain that have been linked to diversity in social behaviors. New technologies allow for unprecedented interrogation of the genes and neural circuitry regulating behaviors, but these approaches often require transgenic models and are most often used in mice. Here we discuss seminal findings relating the oxytocin and vasopressin systems to social behavior with a focus on non-traditional animal models. We then evaluate the potential of using CRISPR/Cas9 genome editing to examine the roles of genes and enable circuit dissection, manipulation and activity monitoring of the oxytocin and vasopressin systems. We believe that it is essential to incorporate these genetic and circuit level techniques in comparative behavioral neuroendocrinology research to ensure that our field remains innovative and attractive for the next generation of investigators and funding agencies.Anorexia nervosa (AN) is an eating disorder characterized by excessive weight loss, persistent food restriction and inappropriate physical activity relative to declining energy balance. find more The comorbidity with depression and/or anxiety disorders might contribute to the “chronicization” of the disease. We aimed here to question first the link between physical activity and anxiety from a clinical investigation of AN patients (n = 206). Then, using a rodent model mimicking numerous physiological and metabolic alterations commonly seen in AN patients, we examined whether 1) chronic food restriction increased anxiety-like behaviour and 2) physical activity plays a role in regulating anxiety levels. To this end, we exposed young female mice to a chronic food restriction (FR, n = 8) paradigm combined or not with access to a running wheel (FRW, n = 8) for two weeks. The mice were compared to a group of mice fed ad libitum without (AL, n = 6) or with running wheel access (ALW, n = 8). We explored anxiety-like behaviour od FRW groups). We conclude that this model (FR and FRW mice) did not express typical anxiety-like behaviour, but that physical activity linked to food restriction improved coping strategies in an anxiogenic context.Objectives To determine progestin-only pill (POP) use at 3 and 6 months postpartum among women who chose POPs at the postpartum visit. Study Design Secondary data analysis of a prospective observational study with telephone interviews at 3 and 6 months postpartum to assess contraceptive use. Results Of 440 women who attended the postpartum visit, 92 (20.9%) chose POPs. Current POP use was 44/84 (52.4%) at 3 months, 33/76 (43.4%) at 6 months, and 32/76 (42.1%) at both 3- and 6-month follow-up assessments. Conclusion About half of women who plan POP use at the postpartum visit are not using this method at 3 months after delivery. Implications About half of women with a prescription for progestin-only pills will be not using this method at 3 months postpartum; further understanding of continued sexual activity and breastfeeding may clarify pregnancy risk for those not reporting modern contraception use during the postpartum period.Toxoplasma gondii is a globally-distributed intracellular parasitic protozoon with wide host range. Chronic infection is the most prevalent form of T. gondii infection, which can lead to significant damage. CD44 plays an important role in body’s immune response, however, little is known about the function and mechanism of CD44 in T. gondii infection until now. In the present study, total RNA isolated from four groups including C57BL/6 mouse (C57), C57BL/6△CD44 mouse(C57△CD44), C57BL/6 mouse infected with T. gondii (C57-TG) and C57BL/6△CD44 infected with T. gondii (C57△CD44-TG)were subjected to comparative transcriptome analyses using RNA-seq techniques to explore the possible function of CD44 in mouse brain during chronic Toxoplasma infection. The results indicated a total of 35,908, 54,428, 51,473 and 22,387 unigenes were annotated in KOG, Swissprot, GO and KEGG databases by transcriptome analysis, respectively, and all the databases shared 9,833 unigenes. Subsequently, differentially expressed GO terms and with the C57-TG mouse. The present study is the first trial for exploring the function of CD44 in the mouse brain during chronic infection with T. gondii at the transcriptional level, which can provide a basis for the study of the host immune defense mechanism against T. gondii infection.Objectives To understand how health status preceding traumatic brain injury (TBI) affects relative functional gain after inpatient rehabilitation using a data mining approach. Design Population-based, sex-stratified, retrospective cohort study using health administrative data from Ontario, Canada (39% of the Canadian population). Setting Inpatient rehabilitation. Participants Patients 14 years or older (N=5,802; 63.4% males) admitted to inpatient rehabilitation within one-year of a TBI-related acute care discharge between April 1, 2008 and March 31, 2015. Interventions Not applicable. Main outcome measures Relative functional gain (RFG) in percent, calculated as [(Discharge FIM-Admission FIM)/(126-Admission FIM) x 100]. Health status prior to TBI was identified and internally validated using a data mining approach that categorized all International Classification of Diseases Version 10 codes for each patient. Results The average RFG among males was 52.8±27.6% and among females, 51.6±27.1%. Sex-specific Bonferroni adjusted multivariable linear regressions identified 10 factors of pre-injury health status related to neurology, emergency medicine, cardiology, psychiatry, geriatrics, and gastroenterology that were significantly associated with reduced RFG in FIM for males.
