Spatiotemporal Effects Of A Controlled-Release Anti-Inflammatory Drug On The Cellular Dynamics Of Host Response, Tram T. Dang, Kaitlin M. Bratlie, Said R. Bogatyrev, Xiao Chen, Robert Langer, Daniel G. Anderson 2011 Massachusetts Institute of Technology

Spatiotemporal Effects Of A Controlled-Release Anti-Inflammatory Drug On The Cellular Dynamics Of Host Response, Tram T. Dang, Kaitlin M. Bratlie, Said R. Bogatyrev, Xiao Chen, Robert Langer, Daniel G. Anderson

Kaitlin M. Bratlie

In general, biomaterials induce a non-specific host response when implanted in the body. This reaction has the potential to interfere with the function of the implanted materials. One method for controlling the host response is through local, controlled-release of anti-inflammatory agents. Herein, we investigate the spatial and temporal effects of an anti-inflammatory drug on the cellular dynamics of the innate immune response to subcutaneously implanted poly(lactic-co-glycolic) microparticles. Noninvasive fluorescence imaging was used to investigate the influence of dexamethasone drug loading and release kinetics on the local and systemic inhibition of inflammatory cellular activities. Temporal monitoring of host response showed that …


Automated Sequence- And Stereo-Specific Assignment Of Methyl-Labeled Proteins By Paramagnetic Relaxation And Methyl–Methyl Nuclear Overhauser Enhancement Spectroscopy, Vincenzo Venditti, Nicolas L. Fawzi, G. Marius Clore 2011 National Institutes of Health

Automated Sequence- And Stereo-Specific Assignment Of Methyl-Labeled Proteins By Paramagnetic Relaxation And Methyl–Methyl Nuclear Overhauser Enhancement Spectroscopy, Vincenzo Venditti, Nicolas L. Fawzi, G. Marius Clore

Vincenzo Venditti

Methyl-transverse relaxation optimized spectroscopy is rapidly becoming the preferred NMR technique for probing structure and dynamics of very large proteins up to ~1 MDa in molecular size. Data interpretation, however, necessitates assignment of methyl groups which still presents a very challenging and time-consuming process. Here we demonstrate that, in combination with a known 3D structure, paramagnetic relaxation enhancement (PRE), induced by nitroxide spin-labels incorporated at only a few surface-exposed engineered cysteines, provides fast, straightforward and robust access to methyl group resonance assignments, including stereoassignments for the methyl groups of leucine and valine. Neither prior assignments, including backbone assignments, for the …

Understanding the structural basis of protein redox activity is still an open question. Hence, by using a structural genomics approach, different albumins have been chosen to correlate protein structural features with the corresponding reaction rates of thiol exchange between albumin and disulfide DTNB. Predicted structures of rat, porcine, and bovine albumins have been compared with the experimentally derived human albumin. High structural similarity among these four albumins can be observed, in spite of their markedly different reactivity with DTNB. Sequence alignments offered preliminary hints on the contributions of sequence-specific local environments modulating albumin reactivity. Molecular dynamics simulations performed on experimental …


Real-Time In Vivo Detection Of Biomaterial-Induced Reactive Oxygen Species, Minglin Ma, Wendy F. Liu, Kaitlin M. Bratlie, Tram Dang, Robert Langer, Daniel G. Anderson 2011 Massachusetts Institute of Technology

Real-Time In Vivo Detection Of Biomaterial-Induced Reactive Oxygen Species, Minglin Ma, Wendy F. Liu, Kaitlin M. Bratlie, Tram Dang, Robert Langer, Daniel G. Anderson

Kaitlin M. Bratlie

The non-specific host response to implanted biomaterials is often a key challenge of medical device design. To evaluate biocompatibility, measuring the release of reactive oxygen species (ROS) produced by inflammatory cells in response to biomaterial surfaces is a well-established method. However, the detection of ROS in response to materials implanted in vivo has not yet been demonstrated. Here, we develop a bioluminescence whole animal imaging approach to observe ROS released in response to subcutaneously-implanted materials in live animals. We compared the real-time generation of ROS in response to two representative materials, polystyrene and alginate, over the course of 28 days. …


The Role Of Ghrelin And Leptin In Obesity: Is Exogenous Administration Of These Hormones A Possible Drug Therapy?, Peri Eckstein 2011 Touro College

The Role Of Ghrelin And Leptin In Obesity: Is Exogenous Administration Of These Hormones A Possible Drug Therapy?, Peri Eckstein

The Science Journal of the Lander College of Arts and Sciences

Ghrelin and leptin are two hormones that have been recognized to have a major influence on energy balance. Leptin is a mediator of long term regulation of energy balance, suppressing food intake and thereby inducing weight loss. Ghrelin, on the other hand, is a fast acting hormone, playing a role in meal initiation. As a growing number of people suffer from obesity, understanding the mechanisms by which various hormones and neurotransmitters influence energy balance has been a subject of intense research. This paper provides background on leptin and ghrelin hormones, their role in food intake and body weight in humans, …


The Effect Of Melatonin On The Ovaries, Jaclyn Starr 2011 Touro College

The Effect Of Melatonin On The Ovaries, Jaclyn Starr

The Science Journal of the Lander College of Arts and Sciences

Melatonin is a very small molecule whose effects can be both detrimental and beneficial to the ovaries depending on its concentration. Too much of anything is usually not good and so is the case with melatonin. Very high doses can be damaging, but in the right amount melatonin may be able to combat various diseases and increase the chances for fertility in women.

Pharmacological Chaperoning In Fabry Disease, Jerome Rogich 2011 University of Massachusetts Amherst

Pharmacological Chaperoning In Fabry Disease, Jerome Rogich

Masters Theses 1911 - February 2014

Fabry Disease is an X-­‐linked lysosomal storage disorder characterized by a variety of symptoms including hypohydrosis, seizures, cardiac abnormalities, skin lesions, and chronic pain. These symptoms stem from a lack of functional endogenous α-­‐ Galactosidase A (α-­GAL), which leads to an accrual of its natural substrate. The severity of the disease symptoms can be directly correlated with the amount of residual enzyme activity. It has been shown that an imino sugar, 1-deoxygalactonojirimycin (DGJ), can increase enzymatic activity and clear excess substrate. This pH-­‐dependent chaperoning phenomenon is believed to arise from the presence of aspartic acid 170 in the active site. …


Antispasmodic And Ca++ Antagonist Potential Of Marrubiin, A Labdane Type Diterpene From Phlomis Bracteosa, Javid Hussain, Riaz Ullah, Arif-ullah Khan, Fazal Mabood, Mohammad Raza Shah, Ahmed Al-Harrasi, Anwar Gilani 2011 Kohat University of Science and Technology, Kohat, Pakistan

Antispasmodic And Ca++ Antagonist Potential Of Marrubiin, A Labdane Type Diterpene From Phlomis Bracteosa, Javid Hussain, Riaz Ullah, Arif-Ullah Khan, Fazal Mabood, Mohammad Raza Shah, Ahmed Al-Harrasi, Anwar Gilani

Department of Biological & Biomedical Sciences

A tricyclic labdane type diterpene was isolated for the first time from ethyl acetate soluble part of Phlomis bracteosa. Its structure was confirmed by x-ray which was found to be marrubiin. When studied in isolated rabbit jejunum, marrubiin caused concentration-dependent relaxation of spontaneous and high K+ (80 mM)-induced contractions, like that caused by verapamil, indicating that marrubiin exhibits spasmolytic activity, possibly mediated through Ca++ channel blocking action.
