Ingestion of Stool…A Promising Therapy for C. difficile Infection

In search of palatable poo

C. difficile
infections are horribly uncomfortable for patients causing painful
cramping, and excessive diarrhea. In
fact, certain strains of C. difficile cause about 250,000
hospitalizations and
14,000 deaths each year in the U.S. The quest for new types of therapy
is because of two big dilemmas with regards to antibiotic treatment.
There is increased antibiotic resistance and they
have a detrimental effect on normal gut flora which protect the body
harmful pathogens. So
here’s the scoop…there’s now hope with ingesting poop!

Many of you
are probably thinking…ingesting stool that sounds rather disgusting but in fact
it is actually pretty brilliant! This
unique treatment has been the focus of current study at Massachusetts General Hospital
(MGH). A recent press release from the hospital describes this study’s objective to
investigate whether delivering FMT orally through capsules designed to open
upon reaching the small intestine would be just as effective as other more
invasive treatments such as delivering frozen fecal material for FMT either by
colonoscopy or nasogastric tube.

A potential role of circulating LHCGR forms for the prediction of preeclampsia in the first trimester of pregnancy

A recent abstract pertaining to using LHCGR forms for the prediction of preeclampsia was presented at the 13th World Congress in Fetal Medicine. The World Congress is designed both for those specializing in
fetal-maternal medicine and those with a more general clinical interest
who want to be updated on developments in the field. Leading
international experts and young researchers present and discuss the
latest developments in fetal medicine. 

To explore the possible role of circulating human chorionic gonadotrophin receptor (LHCGR) forms in the prediction of early and late preeclampsia (PE) in the first trimester of pregnancy, combined with maternal baseline risk, biophysical parameters and angiogenic factors.

A case-control study, within a cohort of 5, 759 pregnancies including 20 cases of early PE, 20 of late PE (cut-off: 34 weeks at delivery), 300controls. Maternal characteristics, mean arterial pressure (MAP), uterine artery (UtA) Doppler (11-13 weeks), placental growth factor (PlGF),soluble Fms-like tyrosine kinase-1 (sFtl-1), circulating sLHCGR, and hCG-LHCGR complexes (8-11 weeks) were measured/recorded.  LHCGR difference (LHCGR-D) was calculated by subtracting hCG-LHCGR value from the corresponding sLHCGR. All parameters were normalized by logarithmic transformation, converted in MoM, and logistic regression analysis was used to predict PE.

Among LHCGR forms, the LHCGR-D improves substantially the prediction for early and late PE in first trimester, if used in algorithms. These new biomarkers seemed useful if used in combination (LHCGR-D) in the context of prediction of PE.

New Study Focuses On Designing Novel Antibodies to Target Breast Cancer Cells

image from

In honor of breast cancer awareness month, we thought we would
share some interesting and hopeful new research. But before discussing
this we should take some time to reflect on the fact that people
afflicted by this disease are battling it everyday and some for
several years. It does seem trivial to only recognize it one month of
every year when you consider all of this, but perhaps this is our way of
setting time aside to focus attention and in some way bring energy,
good vibes, and perhaps fresh ideas to conquer this disease.

A recent study done by the University of Michigan focused on
selecting novel monoclonal antibodies with anticancer activity. They
did this by creating an environment of cancer cells in vitro and then
exposing these cells to numerous antibodies to evaluate if these
antibodies have any anti-cancer fighting effects. How they created the
antibodies is rather intriguing. Read more

Sensitivity of Islet Cell Antibodies (ICA) ELISA Compared with Indirect Immunofluorescence Assay

Type 1 diabetes, also known as insulin-dependent diabetes mellitus, results from a chronic autoimmune process which destructs the insulin-secreting pancreatic beta cells. Before the onset of disease T1D patients may demonstrate autoantibodies against different autoantigens of islet cells. Research indicates that these autoantibodies have been shown to be important markers for the identification of individuals with an increased risk to develop T1D at a time when all metabolic tests available still show normal results.

Islet cell autoantibodies detected by indirect immunofluorescence (IIF) have been the first serological markers described for T1D. This technique using tissue sections from human or primate pancreas, however, still reveals methodological problems, especially with regard to inter-laboratory standardization. After discovery of the two main protein antigens of ICA – the enzyme glutamic acid decarboxylase (GAD65) and the islet cell protein IA2 – it has been possible to measure these specific autoantibodies by radioligand assays and recently by sensitive ELISA.

Risk assessment of T1D can be achieved by the combination of tests for these different autoantibodies. Therefore, the Eagle Biosciences ICA screen ELISA Assay kit – designed for the semiquantitative determination of ICA to enable reliable screening – was compared with IIF as the routine method for the detection of ICA.


The Eagle Biosciences ICA screen ELISA Assay Kit is a robust and sensitive tool for the detection of ICA. In comparison with established methods for the detection of ICA, this assay showed superior sensitivity. These data strongly support further investigation to confirm the better sensitivity of the ICA screen ELISA.

New Discovery that Makes Growing Replacement Organs a Possibility

very thought of being able to grow actual human organs in a laboratory is mind
blowing! There are endless possibilities
for medical research with a recent study performed at the MRC Centre of
Regenerative Medicine in Edinburgh, U.K. Scientists were successfully able to cultivate living cells from an
animal in vitro. The process that they used to do this could
be used for a multitude of medical purposes and therapies for transplant
patients and more. This study was
focused on creating a functional thymus for mice but it brings hope that this process could be
used for humans for creating a variety of other organ tissues. Read more.

cancer still continues to have a bleak prognosis despite many advances in
chemotherapy and surgical procedures .In
fact, pancreatic cancer has the worst survival rate of all cancers with only a
small percentage surviving over 5 years after diagnosis. Now, researchers at
the University of Missouri have discovered that a molecule that can used as a
communication system by bacteria can be manipulated to prevent cancer cells
from not only spreading but possibly killing them all together. Read more This
study demonstrated that using such a molecule to combat cancer decreases cell
viability, promotes apoptosis by activating caspases, and inhibits the wound
healing process. It shows amazing
promise for pancreatic cancer however, further research is needed in vivo. Read more

for pancreatic cancer has increased over the last several years yet it still
only gets one percent of research funding. How is this possible…one of the most
deadly cancers receives only ONE PERCENT of funding?!  Pancreatic cancer is severely underfunded
just like Alzheimer’s as we mentioned in one of our previous blogs, 10 Reasons to Keep with your Vitamin D Levels. We
chose to highlight this new pancreatic cancer research in this blog not only
because it is a significant step towards a cure but also because some folks
from Eagle Biosciences will be walking this weekend in the New England Pancreatic Research Walk in
support of the cause and to support a friend who has lost a loved one.

Lustgarten Foundation is
a private foundation created by Cablevision to
dedicate funding pancreatic research. Cablevision underwrites all of the
foundations costs so that 100% of every donation goes to this research. If you

New Technology:  Aqueous Two Phase System Patterning of Dectection Antibody Solutions for Cross-Reaction Free Multiplex ELISA

Accurate disease diagnosis, patient stratification and biomarker validation require the analysis of multiple biomarkers. This paper describes cross-reactivity-free multiplexing of enzyme-linked immunosorbent assays (ELISAs) using aqueous two-phase systems (ATPSs) to confine detection antibodies at specific locations in fully aqueous environments. Antibody cross-reactions are eliminated because the detection antibody solutions are co-localized only to corresponding surface-immobilized capture antibody spots. This multiplexing technique is validated using plasma samples from allogeneic bone marrow recipients. Patients with acute graft versus host disease (GVHD), a common and serious condition associated with allogeneic bone marrow transplantation, display higher mean concentrations for four multiplexed biomarkers (HGF, elafin, ST2 and TNFR1) relative to healthy donors and transplant patients without GVHD. The antibody co-localization capability of this technology is particularly useful when using inherently cross-reactive reagents such as polyclonal antibodies, although monoclonal antibody cross-reactivity can also be reduced. Because ATPS-ELISA adapts readily available antibody reagents, plate materials and detection instruments, it should be easily transferable into other research and clinical settings.
