Biosynthetic Trilayered Ventricle Pumps Blood
Biomedical engineers at the University of Toronto have developed a method to create a small-scale biosynthetic left ventricle that can pump blood within a bioreactor. While the construct is too small to act as replacement for a human heart, it could ...

This study showed a negative relationship between the gaps and the number of senescence cells. Moreover, we found a similar reduction in 30-month-old naturally and 7-month-old D-gal-induced aging rats. Given these consistent data from different eukaryotic organisms, it suggests that the Youth-DNA-GAP is a marker of phenotype-related aging degree Towards Scaffold-Based Regeneration of Dental Pulp https://www.fightaging.org/archives/2022/06/towards-scaffold-based-regeneration-of-dental-pulp/ Researchers are working towards the ability to regenerate the dental pulp inside teeth.

How is RCA angina different from LAD angina ?
William Heberden first introduced the term angina to the medical community in 1778. His descriptions became immortal. Still, no one would ever know what was the angina-related artery, Heberden was alluding to. Now, some jobless cardiologist is asking this question after 200 years. How is angina from the LAD system differ from the RCA  system? or let me put it another way, How does angina of anterior circulation (LAD) differ from posterior circulation (RCA/LCX)? Though there is distinct hemodynamic profiling of RCAvs LAD ACS, surprisingly, cardiology literature does not answer the chest pain aspect of it. One rare stud...

Futuristic cardiology: Fishing a failing heart !
A path-breaking research is coming up from Jhon Paulson school of engineering, Harvard. It is all about a tiny lab-made bio-hybrid fish that is mechanically engineered with cardiac stem cells. It can generate enough mechanical force that can transform into a biological organ (or assistance)to the heart. Early lab experiments are exciting. We will soon see a stem cell-enriched bio-fish that will dance to the tunes of the cardiac cycle. (See the video below)  Final message Will it become real? or a just a grandeur thought? We have just done Xeno heart transplantat...

Lab-Designed “Fish” Could Pave the Way for Artificial Hearts
Researchers at Harvard University have created a fish-like construct from human stem cell-derived cardiac muscle. The structure can beat and swim autonomously, and is inspired by zebrafish. So far, the researchers have shown that the fish can survive...

INTERMACS classification for advanced heart failure
INTERMACS classification for advanced heart failure was developed as a sub classification for advanced heart failure, typically for those in advanced NYHA (New York Heart Association) Functional Class III and IV. Interagency Registry for Mechanically Assisted Circulatory Support (INTERMACS) developed this classification with seven clinical profiles and an arrhythmia modifier [1].  This was to allow optimal selection of patients for medical and pacing therapies, cardiac transplantation and mechanical circulatory support. They found that 80% of current devices are being used in 2 profiles with the highest level of clinical...

Mural endocarditis
Vegetations in infective endocarditis are usually situated on the valves. If they are located on the walls of the cardiac chambers, it is known as mural endocarditis [1]. When mural endocarditis occurs without any cardiac structural abnormalities like ventricular septal defects, it is called primary mural endocarditis [2]. Primary mural endocarditis is extremely rare. Left atrial mural endocarditis usually occurs due to the jet lesion of mitral regurgitation [1,3]. Left atrial mural endocarditis is usually picked up by trans esophageal echocardiography. Vegetations are mostly located just distal to the mitral orifice betw...

A heart transplant story in a 1-year-old, as told by his mother PODCAST
“In January of 1991, at twenty-two months old, Nick had another heart catheterization. Andy and I had started thinking about the next stage of surgery to finish the heart repair. Just before Nick was discharged, I discussed it briefly with Dr. Kanter.‘Tell me when you would like to do the surgery,’ he said.‘Never,Read more …A heart transplant story in a 1-year-old, as told by his mother [PODCAST] originally appeared inKevinMD.com.

Dark Chocolates and the Heart
Are dark chocolates good for the heart? A study published in Circulation suggests that eating dark chocolate can improve coronary vasomotion and reduce platelet reactivity [1]. Dark chocolates which contain 70% cocoa have lots of flavonoids – potent antioxidants which helps to overcome the oxidative stress. They also decrease the activation of blood platelets responsible for thrombosis. High oxidative stress and limited availability of antioxidants can cause endothelial damage in the arteries, leading to increased chances for a thrombosis. Flavonoid rich dark chocolate has the potential for a beneficial effect on graft ...

Reverse Potts Shunt for Pulmonary Arterial Hypertension in Children
Potts shunt was a surgical anastomosis between left pulmonary artery and descending aorta to improve pulmonary blood flow in cyanotic congenital heart disease with decreased pulmonary blood flow. It is a systemic to pulmonary shunt. The report was published one year after the Blalock-Taussig shunt which was also used for a similar purpose [1]. Later Potts shunt like other central aortopulmonary shunts, were discontinued because of higher risk of excessive pulmonary blood flow. A modified Blalock-Taussig shunt is still in use. Reverse Potts shunt is a pulmonary to systemic shunt for relieving pulmonary arterial hypertensio...

Fight Aging! Newsletter, July 19th 2021
In this study, we developed the first epigenetic clock for domesticated sheep (Ovis aries), which can predict chronological age with a median absolute error of 5.1 months. We have discovered that castrated male sheep have a decelerated aging rate compared to intact males, mediated at least in part by the removal of androgens. Furthermore, we identified several androgen-sensitive CpG dinucleotides that become progressively hypomethylated with age in intact males, but remain stable in castrated males and females. Comparable sex-specific methylation differences in MKLN1 also exist in bat skin and a range of mouse tissu...

In conclusion, the MR exhibited the protective effects against age-related behavioral disorders, which could be partly explained by activating circulating FGF21 and promoting mitochondrial biogenesis, and consequently suppressing the neuroinflammation and oxidative damages. These results demonstrate that FGF21 can be used as a potential nutritional factor in dietary restriction-based strategies for improving cognition associated with neurodegeneration disorders.
