Borrelia burgdorferi infection induces lipid mediator production during Lyme arthritis.

Borrelia burgdorferi infection induces lipid mediator production during Lyme arthritis. Biochimie. 2017 Jun 16;: Authors: Brown CR, Dennis EA Abstract Experimental Lyme arthritis provides a mouse model for exploring the development of pathology following infection of C3H mice with Borrelia burgdorferi. Infected mice develop a reliable inflammatory arthritis of the ankle joint with severity that typically peaks around two to three weeks post-infection and then undergoes spontaneous resolution. This makes experimental Lyme arthritis an excellent model for investigating the mechanisms that drive both the development and resolution phases of inflammatory disease. Eicosanoids are powerful lipid mediators of inflammation and are known to regulate multiple aspects of inflammatory processes. While much is known about the role of eicosanoids in regulating immune responses during autoimmune disease and cancer, relatively little is known about their role during bacterial infection. In this review, we discuss the role of eicosanoid biosynthetic pathways in mediating inflammatory responses during bacterial infection using experimental Lyme arthritis as a model system. We point out the critical role eicosanoids play in disease development and highlight surprising differences between sterile autoimmune responses and those occurring in response to bacterial infection. These differences should be kept in mind when designing therapies and treatments for inflammatory disea...

Authors: Carroll K, Mesman J, McLeod H, Boughey J, Keeney G, Habermann E Abstract Utilising frozen section technologies, Mayo Clinic has one of the lowest reoperation rates for breast lumpectomy in the United States. The research reported on sought to understand the successful teamwork between the Breast Surgery Team and the Frozen Section Laboratory at Mayo Clinic. Researchers worked collaboratively with healthcare staff from breast surgery and the frozen section pathology laboratory to identify communication styles and strategies that contribute to the timely and accurate intraoperative evaluation of breast cance...

ConclusionsNIV showed a significant protective effect for intubation in immunosuppressed patients (cancer and transplants) and in patients with APE/CAP. However, the benefits of NIV for other etiologies are not clear and more trials are needed to prove these effects.

Showalter, Nouri NeamatiAbstractIdentified as a hallmark of cancer, metabolic reprogramming allows cancer cells to rapidly proliferate, resist chemotherapies, invade, metastasize, and survive a nutrient-deprived microenvironment. Rapidly growing cells depend on sufficient concentrations of nucleotides to sustain proliferation. One enzyme essential for the de novo biosynthesis of pyrimidine-based nucleotides is dihydroorotate dehydrogenase (DHODH), a known t...

Ceramide and sphingosine inhibit cell proliferation and induce cell apoptosis while S1P has the opposite effect. Maintaining a metabolic balance of sphingolipids is essential for growth and development of cells. Sphingosine kinase (SPHK) is an important regulator for keeping...

In this study, eutectic mixtures, as binary pharmaceutical compositions of CEL with adipic acid (ADI) and saccharin (SAC), were identified through a phase diagram and Tammann’s triangle intended to improve the wettability and dissolution rate of poorly water-soluble CEL. The contact angles at 0s in the liquid-solid interface were approximately θs (theta) 79.7° ± 0.50° and 86.65° ± 0.45° for CEL-ADI and CEL-SAC, respectively, which were much lower than the value obtained for CEL (92.05° ± 0.75° θ). Moreover, a comparison of the disk intrinsic dissolution rate an...
