Recent studies have demonstrated that paternal stress in rodents can result in modification of offspring behavior. Environmental enrichment, which enhances cognitive stimulation and physical activity, modifies various behaviors and reduces stress responses in adult rodents. We investigated the transgenerational influence of paternal environmental enrichment on offspring behavior and physiological stress response. Adult C57BL/6J male mice (F0) were exposed to either environmental enrichment or standard housing for four weeks and then pair-mated with naïve females...

The aim of this study was to compare liposomal bupivacaine and interscalene nerve block (ISNB) for analgesia after shoulder arthroplasty. We compared 37 patients who received liposomal bupivacaine vs 21 who received ISNB after shoulder arthroplasty by length of hospital stay (LOS), opioid consumption, and postoperative pain. Pain was the same in both groups for time intervals of 1 hour and 8 to 14 hours postoperatively. Compared with ISNB patients, liposomal bupivacaine patients reported less pain at 18 to 24 hours (P = ...

Using a Matlab classification algorithm, we demonstrate that a highly salient distal cue array is required for significantly increased likelihoods of spatial search strategy selection during Morris water maze spatial learning. We hypothesized that increased spatial search strategy selection during spatial learning would be the key measure demonstrating the formation of an allocentric map to the escape location. Spatial memory, as indicated by quadrant preference for the area of the pool formally containing the hidden platform, was assessed as the main measure that this allocentric map had formed during spatial learning...

BACKGROUND: American workers spend 70-80% of their time at work being sedentary. Traditional approaches to increase moderate-vigorous physical activity (MVPA) may be perceived to be harmful to productivity. Approaches that target reductions in sedentary behavior and/or increases in standing or light-intensity physical activity [LPA] may not interfere with productivity and may be more feasible to achieve through small changes accumulated throughout the workday METHODS/DESIGN: This group randomized trial (i...

Preeclampsia is a hypertensive disorder of pregnancy, responsible for over 60 000 maternal deaths annually. Endothelial dysfunction is a central aspect to its pathophysiology, and currently, no medical therapeutic is available for its treatment. In this study, we aim to investigate the effect of epidermal growth factor (EGF) on endothelial dysfunction using primary human tissues. We performed a number of in vitro assays that mimic the vascular endothelial dysfunction that occurs in preeclampsia. Epidermal growth factor reduced the expression of vascular cell adhesion molecule-1, a marker of endothelial dysfunction, after insult with tumor necrosis factor α (TNF-α) or serum from women with preeclampsia...

INTRODUCTION: Preeclampsia is a serious complication of pregnancy affecting 5% of pregnancies. Our team identified 137 genes highly expressed in placenta relative to other human tissues. Here, we have explored a role for steroid sulfatase (STS) in preeclampsia by characterising STS expression and the functional effects of STS on primary placental trophoblasts. METHODS: Characterisation of STS was performed on preterm preeclamptic and gestation-matched normotensive preterm controls who delivered at <34 weeks gestation...

INTRODUCTION: Preeclampsia is a serious complication affecting 5-8% of pregnancies. Central to its pathogenesis is placental hypoxia and inflammation which leads to secretion of soluble fms-like tyrosine kinase 1 (sFlt-1). sFlt-1 causes widespread endothelial dysfunction. The molecular mechanisms regulating sFlt-1 production remain poorly understood. Recently, a binding site for the nuclear factor activated T cells (NFAT) transcription factor has been found on fms-like tyrosine kinase 1 (FLT-1) promoter...

BACKGROUND: Pleural ultrasound guidance reduces complications of pleural procedures, and lung ultrasound can diagnose the cause of acute respiratory failure. Yet as recently as five years ago, many respiratory physicians lacked sufficient access, training and expertise to perform chest ultrasound. AIMS: This study examines whether progress has been achieved in chest ultrasound amongst respiratory physicians in Australia and New Zealand. METHODS: We conducted a web-based chest ultrasound survey of adult respiratory physicians across Australia and New Zealand...

Deficiency in PTEN (phosphatase and tensin homolog deleted on chromosome 10) is the underlying cause of PTEN hamartoma tumor syndrome and a wide variety of human cancers. In skin epidermis, we have previously identified an autocrine FGF signaling induced by loss of Pten in keratinocytes. In this study, we demonstrate that skin hyperplasia requires FGF receptor adaptor protein Frs2α and tyrosine phosphatase Shp2, two upstream regulators of Ras signaling. Although the PI3-kinase regulatory subunits p85α and p85β are dispensable, the PI3-kinase catalytic subunit p110α requires interaction with Ras to promote hyperplasia in Pten-deficient skin, thus demonstrating an important cross-talk between Ras and PI3K pathways...

Recurrent bacterial infections are a significant burden worldwide, and prior history of infection is often a significant risk factor for developing new infections. For urinary tract infection (UTI), a history of two or more episodes is an independent risk factor for acute infection. However, mechanistic knowledge of UTI pathogenesis has come almost exclusively from studies in naive mice. Here we show that, in mice, an initial Escherichia coli UTI, whether chronic or self-limiting, leaves a long-lasting molecular imprint on the bladder tissue that alters the pathophysiology of subsequent infections, affecting host susceptibility and disease outcome...

Embryo implantation requires synchronized dialogue between the receptive endometrium and activated blastocyst via locally produced soluble mediators. During the mid-secretory (MS) phase of the menstrual cycle, increased glandular secretion into the uterine lumen provides important mediators that modulate the endometrium and support the conceptus during implantation. Previously we demonstrated the importance of vascular endothelial growth factor (VEGF) in the human uterus, particularly with respect to embryo implantation...

Gram-negative uropathogenic Escherichia coli (UPEC) bacteria are a causative pathogen of urinary tract infections (UTIs). Previously developed antivirulence inhibitors of the type 1 pilus adhesin, FimH, demonstrated oral activity in animal models of UTI but were found to have limited compound exposure due to the metabolic instability of the O-glycosidic bond (O-mannosides). Herein, we disclose that compounds having the O-glycosidic bond replaced with carbon linkages had improved stability and inhibitory activity against FimH...
