Cardiac Inflammation and Repair Following Myocardial InfarctionInsideScientific
Join Dr. Merry Lindsey as she discusses her research involving the physiology of recovery from cardiac events.
Age plays a pivotal role in the deterioration of cardiovascular functionality, resulting in an increased risk of cardiovascular disease in older adults. The prevalence of cardiovascular disease has also been shown to increase with age, in both men and women, including the prevalence of atherosclerosis, stroke and, myocardial infarction.
Following myocardial infarction (MI), the left ventricle (LV) undergoes a series of cardiac wound healing responses that involve both the stimulation of robust inflammation to clear necrotic myocytes and tissue debris and the induction of extracellular matrix (ECM) protein synthesis to generate an infarct scar. Collectively, this process in known as LV remodeling. Matrix metalloproteinase-9 (MMP-9) is a key regulator of LV remodeling post-MI, through direct effects on ECM turnover as well as indirect effects on the regulation of the major cell types that coordinate cardiac wound healing- namely the infiltrating leukocytes and the cardiac fibroblasts. We will discuss recent research that has expanded our understanding of MI LV remodeling, including recent proteomic advances focused on the ECM compartment to provide novel functional and translational insights. In summary, this webinar will provide an overview of how cardiac ECM research has evolved over the last decade and will provide insight into future directions that will drive further understanding of MMP directed cardiac ECM turnover after MI.
amilial hematuria is a group of inherited glomeular disease that presented with persistant hematuria from childhood. The most frequent cause is thin based membrane disease (COL4A3 or COL4A4 gene mutation). Alport syndrome has a range of presentation of hematuria, proteinuria, sensorineural hearing loss and end stage renal disease depends on the pattern of inheritance of x-linked recessive, autosomal dominant or recessive (mutation COL4A5). Besides that, a syndromic form of AD hematuria with cataract, marcorthrombocytopenia, sensory hearing loss, and nephropathy with the risk of ESRD in early adulthood (mutation MYH9).
There is no curative treatment for Alport syndrome, RAAS inhibition early of childhood has shown significantly slow the progression of chronic kidney disease. Several novel medication improved renal outcome on animals but have not been tested in human.
The other causes of FH are IgA nephropathy, C3 glomerulopathy including (Dense disease, C3 glomerulonephrtis, complement factor H related 5 (CFHR5) nephropathy) ( mutation in genes proteins that regulate alternative complement pathway). There are some case series illustrate the efficacy of eculizumab in native C3 glomeulopathy. Glomerulopathy with fibronectin deposits is another cause of FH (mutation FN1, inherited AD) with no definitive cure.
Familial Mediterenian Fever is another hereditary disease that might present with recurrent microscopic or gross hematuria (mutation M694V). Colchicn and some biological agents was suggested as therapy. Amyloidosis and end stage renal disease occur in follow up.

Aging and the Cardiovascular System; An in vivo and in vitro approach to the ...Scintica Instrumentation
Almost one third of deaths world-wide can be attributed to cardiovascular diseases (CVD). More than half of those cases are related to systemic arterial hypertension (SAH). There are several risk factors that contribute to the development of SAH. Type II diabetes causes structural and functional damage to arterial walls, which leads to stiffness of compliance vessels and eventually SAH. Some studies have also related oxidative stress, genetics, and neuroendocrine changes to increasing stiffness. Another risk factor that effects everyone is age, and this webinar will explore the effect of vascular aging and how vascular aging and arterial stiffness can be assessed.
Experimental and clinical studies have demonstrated that changes in small artery structure and function are associated with age. These changes include decreased lumen diameter, increased wall thickness and diminished vasoreactivity. Other risk factors such as hypertension and diabetes accelerate and exacerbate these changes. Quantifying these parameters using isolated and pressurized, perfused, cannulated blood vessels is an ideal way to aid in elucidating the underlying causes of these changes to the vasculature and as they relate to aging and cardiovascular health.
Measuring stiffness in progressive diseases can be challenging, but pulse wave velocity (PWV) is considered the gold standard to assess arterial stiffness in vivo. There is epidemiological evidence of the predictive value of PWV for cardiovascular events, and PWV assessment can be done non-invasively and longitudinally for monitoring the progression and improvement of arterial stiffness through different disease models and treatments. For translational researchers, the PWV measurement technique can be adapted from the traditional clinical technique to be used to assess PWV in preclinical animal research studies. As many of the models for CVD use rodents, PWV in small animals is one of the best ways to monitor treatment efficacy and disease progression for pre-clinical research.
By combining these two modalities, both in vivo and in vitro, researchers can assess arterial stiffness and resulting vascular dysfunction. In this webinar we will discuss both methodologies, the techniques and instrumentation used, and some relevant journal articles that use these techniques to assess vascular aging.
This webinar will cover the following topics:
Vascular stiffness, systemic arterial hypertension and other associated effects of aging on the cardiovascular system
Pulse Wave Velocity (PWV) and Pressure Arteriography and how they can be used to assess arterial stiffness:
PWV as the gold-standard for longitudinal, non-invasive estimates of arterial stiffness
Pressure Arteriography and why it is essential for measuring isolated vessel structure and function to assess vascular activity
A brief summary of relevant literature
Vevo 3100 - The ultimate preclinical imaging experience. The Vevo 3100 is a new and innovative platform created for the future of imaging. It combines ultra high frequency ultrasound imaging, quantification and education in a convenient all-in-one touchscreen platform.
Tumor angiogenesis is currently one of the key focal points in biomedical research. It is based upon the hypothesis laid out by Judah Folkman in 1971 that neovasculature is needed to support the growth and metastasis of tumors, and thus anti-angiogenic treatment might be an effective way to cure cancer. Genentech’s anti-VEGF-A drug Avastin a great demonstration of this concept, generating more than $2.7 billion of sales in 2008.
Breast cancer research in animal models has long been hindered by the lack of a fast, portable, high resolution, research and animal focused imaging system that can visualize 2D tumor size, 3D tumor volume, neoangiogenesis and blood perfusion in vivo, in real-time and most importantly, non-invasively.
White Paper: In vivo Fiberoptic Fluorescence Microscopy in freely behaving miceFUJIFILM VisualSonics Inc.
Fiberoptic fluorescence microscopy (FFM) employs optical fibers as small as 300 micrometers in diameter and offers the ability to image cellular and subcellular processes in deep brain structures including the Ventral Tegmental Area (VTA) and the substantia nigra (Sn).
Radiotherapy and chemotherapy aim at killing tumor cells or at least stopping their multiplication. Those therapies have strong limitations: first, their inherent toxicity is not limited to tumoral cells, but also affects healthy tissue; second, only the strongest and most resistant tumoral cells are able to survive, leading to increasingly aggressive tumors.
Development and Validation of a Combined Photoacoustic Micro-Ultrasound Syste...FUJIFILM VisualSonics Inc.
Photoacoustic (PA) Imaging can estimate the spatial distribution of oxygen saturation (sO2) and total hemoglobin concentration (HbT) in blood, and be co-registered with B-Mode ultrasound images of the surrounding anatomy. This study will focus on the development of a PA imaging mode on a commercially available array based micro-ultrasound (μUS) system that is capable of creating such images.
Microdialysis is an integral part of preclinical research to determine extracellular fluid and blood concentrations of metabolites, hormones, drugs, etc, and is often used in quantifying the biochemistry of brain and peripheral tissues. However, it is a molecular-only technique and other imaging modalities are needed to provide the researcher with functional and anatomical information of the animal in vivo.
In this application, Cellvizio was used to study the neuronal degeneration and regeneration processes in live, anaesthetized, adult Thy1-YFP transgenic mice.
Abdominal Aortic Aneurysm (AAA) is a serious and potentially fatal disease that is prevalent in the older population. Scientists are making use of animal models to study the progression of this disease and the effects of therapeutic interventions over longitudinal studies.
VisualSonics has introduced a revolutionary micro-ultrasound and photoacoustic imaging system that allows researchers to collect a plethora of important data over the lifespan of animals, thereby significantly reducing the number of animals needed.
Ischemia - or the lack of blood supply to a tissue - and subsequent reperfusion induces physiological and biochemical changes in the affected tissue and is an important area of study since the damage that occurs as a result is clinically important in diabetes and stroke.
Application Brief: Tumor Microenvironment Imaging with Photoacoustic TechnologyFUJIFILM VisualSonics Inc.
Photoacoustics (PA) combines optical contrast with the high spatial resolution and deep tissue penetration offered by ultrasound. Such applications are especially beneficial for monitoring tumor development, measuring blood concentration changes within it, and quantifying networks of vasculature formation and carcinoma growth over time.

RESULTS: Overall life span (LS) was 2252.1±1742.5 days and cumulative 5-year survival (5YS) reached 73.2%, 10 years – 64.8%, 20 years – 42.5%. 513 LCP lived more than 5 years (LS=3124.6±1525.6 days), 148 LCP – more than 10 years (LS=5054.4±1504.1 days).199 LCP died because of LC (LS=562.7±374.5 days). 5YS of LCP after bi/lobectomies was significantly superior in comparison with LCP after pneumonectomies (78.1% vs.63.7%, P=0.00001 by log-rank test). AT significantly improved 5YS (66.3% vs. 34.8%) (P=0.00000 by log-rank test) only for LCP with N1-2. Cox modeling displayed that 5YS of LCP significantly depended on: phase transition (PT) early-invasive LC in terms of synergetics, PT N0—N12, cell ratio factors (ratio between cancer cells- CC and blood cells subpopulations), G1-3, histology, glucose, AT, blood cell circuit, prothrombin index, heparin tolerance, recalcification time (P=0.000-0.038). Neural networks, genetic algorithm selection and bootstrap simulation revealed relationships between 5YS and PT early-invasive LC (rank=1), PT N0—N12 (rank=2), thrombocytes/CC (3), erythrocytes/CC (4), eosinophils/CC (5), healthy cells/CC (6), lymphocytes/CC (7), segmented neutrophils/CC (8), stick neutrophils/CC (9), monocytes/CC (10); leucocytes/CC (11). Correct prediction of 5YS was 100% by neural networks computing (area under ROC curve=1.0; error=0.0).
CONCLUSIONS: 5YS of LCP after radical procedures significantly depended on: 1) PT early-invasive cancer; 2) PT N0--N12; 3) cell ratio factors; 4) blood cell circuit; 5) biochemical factors; 6) hemostasis system; 7) AT; 8) LC characteristics; 9) LC cell dynamics; 10) surgery type: lobectomy/pneumonectomy; 11) anthropometric data. Optimal diagnosis and treatment strategies for LC are: 1) screening and early detection of LC; 2) availability of experienced thoracic surgeons because of complexity of radical procedures; 3) aggressive en block surgery and adequate lymph node dissection for completeness; 4) precise prediction; 5) adjuvant chemoimmunoradiotherapy for LCP with unfavorable prognosis.

Flu Vaccine Alert in Bangalore Karnatakaaddon Scans
As flu season approaches, health officials in Bangalore, Karnataka, are urging residents to get their flu vaccinations. The seasonal flu, while common, can lead to severe health complications, particularly for vulnerable populations such as young children, the elderly, and those with underlying health conditions.
Dr. Vidisha Kumari, a leading epidemiologist in Bangalore, emphasizes the importance of getting vaccinated. "The flu vaccine is our best defense against the influenza virus. It not only protects individuals but also helps prevent the spread of the virus in our communities," he says.
This year, the flu season is expected to coincide with a potential increase in other respiratory illnesses. The Karnataka Health Department has launched an awareness campaign highlighting the significance of flu vaccinations. They have set up multiple vaccination centers across Bangalore, making it convenient for residents to receive their shots.
To encourage widespread vaccination, the government is also collaborating with local schools, workplaces, and community centers to facilitate vaccination drives. Special attention is being given to ensuring that the vaccine is accessible to all, including marginalized communities who may have limited access to healthcare.
Residents are reminded that the flu vaccine is safe and effective. Common side effects are mild and may include soreness at the injection site, mild fever, or muscle aches. These side effects are generally short-lived and far less severe than the flu itself.
Healthcare providers are also stressing the importance of continuing COVID-19 precautions. Wearing masks, practicing good hand hygiene, and maintaining social distancing are still crucial, especially in crowded places.
Protect yourself and your loved ones by getting vaccinated. Together, we can help keep Bangalore healthy and safe this flu season. For more information on vaccination centers and schedules, residents can visit the Karnataka Health Department’s official website or follow their social media pages.
Stay informed, stay safe, and get your flu shot today!
