Google Maps for the human body: a biomedical revolution

UNSW biomedical engineer Melissa Knothe Tate is using previously top-secret semiconductor technology to zoom through organs of the human body, down to the level of a single cell.

Using Google algorithms, Professor Knothe Tate – an engineer and expert in cell biology and regenerative medicine – is able to zoom in and out from the scale of the whole joint down to the cellular level “just as you would with Google Maps”, reducing to “a matter of weeks analyses that once took 25 years to complete”.

Her team is also using cutting-edge microtome and MRI technology to examine how movement and weight bearing affects the movement of molecules within joints, exploring the relationship between blood, bone, lymphatics and muscle.

The first portable DNA sequencing laboratory

As one of the first research Institutes to take part in the MinION Access Programme (MAP) for portable DNA sequencing, introduced by Oxford Nanopore Technologies, The Genome Analysis Centre (TGAC)’s task force share their experience of the ground breaking trial so far

The team of scientists from TGAC’s Data Infrastructure and Algorithms and Plant and Microbial Genomics groups trialled the miniaturised sensing system by sequencing environmental samples, containing DNA from hundreds or thousands of different organisms.

The team experimented first with a mock community, where they used a simple set of DNA samples from twenty bacteria, created for the Human Microbiome Project. Having developed their experimental and data methods, they then tested real environmental samples sequencing them on the MinION and Illumina platforms for comparison.

Lowering LDL Cholesterol Is Good, but How and in Whom?

Genetic findings reported approximately 9 years ago in the Journal indicated that rare sequence variants in the gene encoding proprotein convertase subtilisin–kexin type 9 serine protease (PCSK9) were associated with significantly lower long-term plasma levels of low-density lipoprotein (LDL) cholesterol. The observed reduction in LDL cholesterol levels was similar to that attained with moderate-intensity statin therapy. The benefits of lifelong lowering of LDL cholesterol levels were substantial; a 47 to 88% lower risk of coronary heart disease was observed over a period of 15 years in middle-aged persons with such genetic polymorphisms. Further genetic studies indicated that PCSK9 activity was a major determinant of plasma levels of LDL cholesterol in humans.

Borrelia burgdorferi pleomorphic forms

Spirochete bacteria Borrelia burgdorferi sensu lato is the causative agent of Lyme disease, the most common tick-borne infection in the Northern hemisphere. There is a long-standing debate regarding the role of pleomorphic forms in Lyme disease pathogenesis, while very little is known about the characteristics of these morphological variants. Here, we present a comprehensive analysis of B. burgdorferi pleomorphic formation in different culturing conditions at physiological temperature. Interestingly, human serum induced the bacteria to change its morphology to round bodies. In addition, biofilm-like colonies in suspension were found to be part of B. burgdorferi's normal in vitro growth. Further studies provided evidence that spherical round bodies had an intact and flexible cell envelope demonstrating that they are not cell wall deficient, or degenerative as previously implied. However, the round bodies displayed lower metabolic activity compared to spirochetes. Furthermore, our results indicated that the different pleomorphic variants were distinguishable by having unique biochemical signatures. Consequently, pleomorphic B. burgdorferi should be taken into consideration as being clinically relevant and influence the development of novel diagnostics and treatment protocols.

C-reactive protein boosts antibody-mediated platelet destruction

C-reactive protein (CRP) enhances IgG-mediated phagocytosis of platelets and patients with immune thrombocytopenia (ITP) have elevated CRP levels, which predicted slower platelet recoveries and bleeding severity.

Binding of antiplatelet antibodies (Ab) to platelets (Plt) triggers platelet oxidation, which also requires the phagocyte NADPH oxidase system. Platelet oxidation exposes oxidized phosphorylcholine (Ox PC) residues from the platelet membrane, providing a Ca2+-dependent binding platform for CRP. CRP subsequently boosts antibody-mediated platelet phagocytosis via phagocytic FcRs.

Teenager diagnosed with testicular cancer after pregnancy test

A teenager was diagnosed with testicular cancer after taking a pregnancy test that came back positive.
Byron Geldard, then 18, had finished school and had just returned from a summer holiday with friends when he received the diagnosis the day before he was due to get his A’ Level results.
Pregnancy tests are increasingly used to diagnose, or rule out, testicular cancer as the illness produces the same hCG hormone that is produced by the developing placenta.
Byron said it was difficult to come to terms with the news and that it took him a while to accept what was happening.

Reducing Microscopic Variation

As any good bench technologist knows, quality is in the details. But details bedevil quality in sources of error that affect the precision and accuracy of test results. In labs where automation is common and less sample handling is required for hands-on testing, light microscopy is still fraught with human error. Understanding sources of microscopic variation in hematology will help you develop a strategy that improves quality.

Generally, sources of error arise from preanalytical, analytical, or post-analytical phases that can create variation throughout the microscopic process. These errors may be random or systematic. A comprehensive quality program considers these sources of error and contains strategies to detect and correct process-related errors.

CDC New HIV Testing Algorithm

In June 2014, CDC recommended a new approach for HIV testing in laboratories, which capitalizes on the latest technology to improve the diagnosis of acute infection. The recommendations feature a new testing algorithm that allows the diagnosis of acute HIV infection as much as 3-4 weeks earlier than the previous testing approach.

The new algorithm begins with a combination immunoassay that detects HIV-1 and HIV-2 antibodies and HIV-1 p24 antigen. This test is more sensitive in diagnosing early infection because it detects the HIV-1 p24 antigen, which appears before antibodies develop.

Specimens reactive on the screening fourth-generation assay are tested with a supplemental assay that differentiates HIV-1 and HIV-2 antibodies. Specimens that are reactive on the initial fourth-generation assay but nonreactive or indeterminate on the antibody differentiation assay are then tested for HIV-1 RNA to differentiate acute HIV infection from a false-positive screening result.

How blood group O protects against malaria

It has long been known that people with blood type O are protected from dying of severe malaria. In a study published in Nature Medicine, a team of Scandinavian scientists explains the mechanisms behind the protection that blood type O provides, and suggest that the selective pressure imposed by malaria may contribute to the variable global distribution of ABO blood groups in the human population.

A team of scientists led from Karolinska Institutet in Sweden have now identified a new and important piece of the puzzle by describing the key part played by the RIFIN protein. Using data from different kinds of experiment on cell cultures and animals, they show how the Plasmodium falciparum parasite secretes RIFIN, and how the protein makes its way to the surface of the blood cell, where it acts like glue. The team also demonstrates how it bonds strongly with the surface of type A blood cells, but only weakly to type O.

This study ties together previous findings. It can explain the mechanism behind the protection that blood group O provides against severe malaria, which can, in turn, explain why the blood type is so common in the areas where malaria is common. In Nigeria, for instance, more than half of the population belongs to blood group O, which protects against malaria.”

Morbillivirus Infections

Research on morbillivirus infections has led to exciting developments in recent years. Global measles vaccination coverage has increased, resulting in a significant reduction in measles mortality. In 2011 rinderpest virus was declared globally eradicated – only the second virus to be eradicated by targeted vaccination. Identification of new cellular receptors and implementation of recombinant viruses expressing fluorescent proteins in a range of model systems have provided fundamental new insights into the pathogenesis of morbilliviruses, and their interactions with the host immune system. Nevertheless, both new and well-studied morbilliviruses are associated with significant disease in wildlife and domestic animals. This illustrates the need for robust surveillance and a strategic focus on barriers that restrict cross-species transmission. Recent and ongoing measles outbreaks also demonstrate that maintenance of high vaccination coverage for these highly infectious agents is critical.

The genus Morbillivirus belongs to the virus family Paramyxoviridae, a group of enveloped viruses with non-segmented, negative strand RNA genomes. It contains viruses that are highly infectious, spread via the respiratory route, cause profound immune suppression, and have a propensity to cause large outbreaks associated with high morbidity and mortality in previously unexposed populations. In populations with endemic virus circulation, the epidemiology changes to that of a childhood disease, as hosts that survive the infection normally develop lifelong immunity.

Paroxysmal cold hemoglobinuria presenting during pregnancy

Paroxysmal cold hemoglobinuria is caused by a biphasic IgG autoantibody that triggers complement-mediated intravascular hemolysis. Paroxysmal cold hemoglobinuria has not previously been reported to occur in association with pregnancy.

An 18 year old female who presented in early pregnancy with acute hemolytic anemia and a positive Donath-Landsteiner antibody test. She was diagnosed with paroxysmal cold hemoglobinuria and treated supportively. Her hemolysis resolved within 6 weeks. Because maternal IgG autoantibodies can cross the placenta, the patient was monitored closely throughout her pregnancy for recurrence. The outcome of the pregnancy was successful, with no evidence of neonatal anemia or hemolysis.

This patient had a classic presentation of paroxysmal cold hemoglobinuria with rapid onset of hemolytic anemia that resolved spontaneously. To our knowledge, this is the first report of paroxysmal cold hemoglobinuria presenting during pregnancy.

Do We Need Procalcitonin for Sepsis?

Globally, sepsis and its complications are a major cause of acute illness and death. The American College of Chest Physicians and Society of Critical Care Medicine defined sepsis as systemic inflammatory response caused by infection. However, the major challenge remains, how can we prove there is an infection? Culture best identifies it, but only in about 30% of patients with sepsis. False positivity of cultures further complicates the situation. Clinical signs of sepsis—including fever, tachycardia, and leucocytosis—are non-specific and overlap with signs of systemic inflammatory response syndromes (SIRS) of non-infectious origin, making detection of sepsis a clinical challenge. As a result, delay in diagnosis and treatment of sepsis is responsible for increased mortality.

In order to prove the presence of bacterial infection, serum biomarkers like procalcitonin (PCT) are considered useful. Biochemically, PCT is the prohormone of the hormone calcitonin, released into the circulation in response to bacterial infection. PCT is the best-studied sepsis biomarker for clinical use. Among all sepsis markers, only PCT has achieved universal use throughout developed countries in the last decade.

Howell-Jolly bodies in sickle cell anemia

The pathophysiology behind Howell-Jolly bodies and nucleated red blood cells in patients with sickle cell anemia is the same: the patient has effectively lost his or her spleen.

"Pretend you’re a sickle cell for a minute. You’re stuck in this strange, elongated shape, and you’re not deformable like you once were. Floating through big vessels is easy, but once you get to capillaries, it becomes difficult to squeeze through without getting stuck. Once you get stuck, other red cells (both sickled and non-sickled) pile up behind you, and pretty soon, no blood is going through that vessel at all."

Normal Pap Smear

Normal cells of the cervix consist basically of squamous, glandular, and metaplastic epithelial cells. The squamous cells line the ectocervix (outer portion) as well as the vagina, and the glandular cells line the endocervix (the inner portion). Squamous metaplastic cells originate from the transformation zone of the cervix where the inner (endocervix) and outer (ectocervix) meet. In order for the cell sample to be satisfactory, endocervical or metaplastic cells must be present as most cervical cancers originate at this highly active transformation zone. Normal appearing endometrial cells may occasionally be seen in association with menses (between Day 1 and12 of the menstrual cycle).

A Short History of the Discovery of Viruses

While people were aware of diseases of both humans and animals now known to be caused by viruses many hundreds of years ago, the concept of a virus as a distinct entity dates back only to the very late 1800s. Although the term had been used for many years previously to describe disease agents, the word “virus” comes from a Latin word simply meaning “slimy fluid”.

Morphology of Myeloid Precursors

The earliest morphologically distinct myeloid cell is a myeloblast. Cell with myeloid commitment at stages of differentiation between the pleuripotant stem cell and myeloblasts have been identified but these lack morphological characters of a myeloid lineage. Myeloid cells share a common precursors with the cells of the monocyte-macrophage system in the form of CFU-GM. CFU-GM matures into CFU-G, a precursor for myeloid cells and CFU-M, a precursor for cells of the monocyte-macrophage series. There are five morphological distinct stages of myeloid precursors, myeloblast, promyelocyte, myelocyte, metamyelocyte and the band form. Only the first three are capable of cell division. Myeloid cells in the peripheral blood are classified into neutrophils, eosinophils and basophils depending on the staining characteristics of the cytoplasmic granules. Morphological evidence of commitment one of the myeloid lines is seen at the myelocyte stage. Electron microscopically commitment can be seen at the promyelocyte stage.

Miracle stem cell therapy reverses multiple sclerosis

A pioneering new stem cell treatment is allowing multiple sclerosis sufferers to walk, run and even dance again, in results branded ‘miraculous’ by doctors. Patients who have been wheelchair-bound for 10 years have regained the use of their legs in the groundbreaking therapy, while others who were blind can now see again. The treatment, is the first to reverse the symptoms of MS, which has no cure, and affects around 100,000 people in Britain.

During the treatment, the patient's stem cells are harvested and stored. Then doctors use aggressive drugs which are usually given to cancer patients to completely destroy the immune system.  The harvested stem cells are then infused back into the body where they start to grow new red and white blood cells within just two weeks. Within a month the immune system is back up and running fully and that is when patients begin to notice that they are recovering.

First Lipoprotein(a) Particle Concentration Assay

Researchers at Health Diagnostic Laboratory Inc. (HDL Inc.) have developed a novel, proprietary method to measure atherogenic lipoprotein(a) particle concentration [Lp(a)-P]. The new method relies on modern immuno-electrophoretic techniques that separate and identify particles based on their charge and size, as opposed to current assays that measure either the amount of cholesterol contained in the Lp(a) fraction or, more commonly, the total mass of the Lp(a) particles in the circulation.

"With this breakthrough in Lp(a) analytical methodology, we are finally able to assess Lp(a) particle concentrations - which we think can be more powerful than Lp(a) mass or cholesterol - as predictors of cardiovascular risk," said Joseph McConnell, PhD, senior author of the paper and president and CEO of HDL Inc.
