How To Avoid China ’ s Medicine Monopoly
I want to share a shocking statistic with you… Around 80% of all the pharmaceuticals sold in America — both prescription and over-the-counter — are manufactured in China. I’m talking about drugs for Parkinson’s and Alzheimer’s, blood pressure and blood thinners, diuretics, aspirin, antibiotics, and a big chunk of the world’s insulin and diabetes drugs — just to name a few.1 We don’t even make penicillin anymore. The last penicillin plant in the U.S. closed its doors in 2004. Americans who rely on medicine are now almost entirely at the mercy of a country whose relations with the U.S. have become more ...

Unlucky numbers: Fighting murder convictions that rest on shoddy stats
LEIDEN, THE NETHERLANDS— When a Dutch nurse named Lucia de Berk stood trial for serial murder in 2003, statistician Richard Gill was aware of the case. But he saw no reason to stick his nose into it. De Berk was a pediatric nurse at Juliana Children’s Hospital in The Hague. In 2001, after a baby died while she was on duty, a colleague told superiors that De Berk had been present at a suspiciously high number of deaths and resuscitations. Hospital staff immediately informed the police. When investigators reexamined records from De Berk’s shifts, they found 10 suspicious incidents. Three other hospitals where D...

KCa3.1 deficiency attenuates neuroinflammation by regulating an astrocyte phenotype switch involving the PI3K/AKT/GSK3 β pathway.
KCa3.1 deficiency attenuates neuroinflammation by regulating an astrocyte phenotype switch involving the PI3K/AKT/GSK3β pathway. Neurobiol Dis. 2019 Aug 27;:104588 Authors: Wei T, Wang Y, Xu W, Yan L, Chen H, Yu Z Abstract Neuroinflammation may induce a phenotype switch to reactive astrogliosis in neurodegenerative disorders. The calcium-activated potassium channel (KCa3.1) is active in the phenotypic switch that occurs during astrogliosis in Alzheimer's disease and ischemic stroke. Here, transcriptome sequencing (RNA-Seq), immunohistochemistry, western blotting, pharmacological blockade, and calcium...

Impaired Activity of Ryanodine Receptors Contributes to Calcium Mishandling in Cardiomyocytes of Metabolic Syndrome Rats
Conclusion Principal findings of this work are that abnormal Ca2+ transient amplitude, contractile dysfunction; and impaired relaxation of MetS cardiomyocytes underlies intrinsic dysfunctional RyR2 and SERCA pump. Abnormal activity of RyRs was evidenced by its decreased ability to bind [3H]-ryanodine. Although the MetS condition does not modify RyR2 protein expression, its phosphorylation at Ser2814 is decreased, which impairs its capacity for activation during ECC. The dysfunctional RyRs, together with a decreased activity of SERCA pump due to decreased Thr17-PLN phosphorylation suggest a downregulation of CaMKII in MetS...

Atrial Transcriptional Profiles of Molecular Targets Mediating Electrophysiological Function in Aging and Pgc-1 β Deficient Murine Hearts
Conclusion: These findings limit the possible roles of gene transcriptional changes in previously reported age-dependent pro-arrhythmic electrophysiologial changes observed in Pgc-1β-/- atria to an altered Ca2+-ATPase (Atp2a2) expression. This directly parallels previously reported arrhythmic mechanism associated with p21-activated kinase type 1 deficiency. This could add to contributions from the direct physiological outcomes of mitochondrial dysfunction, whether through reactive oxygen species (ROS) production or altered Ca2+ homeostasis. Introduction Atrial arrhythmias constitute a major public health pro...

Nrf2 as a Potential Mediator of Cardiovascular Risk in Metabolic Diseases
Conclusion Activation of the Nrf2-dependent antioxidant system plays an important role in cell defense against oxidative stress damage, whereas the insufficiency of the Nrf2 system is associated with multiple aspects of the genesis and progression of metabolic diseases, posing a great risk to the cardiovascular system (Figure 1). The systemic increase of Nrf2 activity by several activators may be beneficial in the treatment of metabolic diseases. In addition, selective upregulation of Nrf2 genes may represent a potential therapy in obesity, diabetes and atherosclerosis. Looking to the future, experimental research that el...

Role of TREK-1 in Health and Disease, Focus on the Central Nervous System
Conclusion and Perspectives Since their cloning 20 years ago, the physiological importance of TREK-1 channels has continued to grow (Figure 3). Today, TREK-1 channels have been shown to be important and their presence is essential in a number of physiopathological processes. Their involvement in these different processes demonstrate the necessity to design pharmacological modulators, activators or inhibitors, of these channels to correct any TREK-1-related dysfunctions. Despites a number of studies and many molecule screenings, only few putative new drugs were identified. The activators belonging to the ML and BL series ...

10 Ways to Keep Your Heart Healthy
No one ever had fun visiting the cardiologist. ­Regardless of how good the doc might be, it’s always a little scary thinking about the health of something as fundamental as the heart. But there are ways to take greater control—to ensure that your own heart health is the best it can be—even if you have a family history of cardiovascular disease. Although 50% of cardiovascular-disease risk is genetic, the other 50% can be modified by how you live your life, according to Dr. Eugenia Gianos, director of Women’s Heart Health at Lenox Hill Hospital in New York City. “This means you can greatly ...

ATP-Sensitive Potassium Channels and Their Physiological and Pathophysiological Roles.
Authors: Tinker A, Aziz Q, Li Y, Specterman M Abstract ATP sensitive potassium channels (KATP ) are so named because they open as cellular ATP levels fall. This leads to membrane hyperpolarization and thus links cellular metabolism to membrane excitability. They also respond to MgADP and are regulated by a number of cell signaling pathways. They have a rich and diverse pharmacology with a number of agents acting as specific inhibitors and activators. KATP channels are formed of pore-forming subunits, Kir6.1 and Kir6.2, and a large auxiliary subunit, the sulfonylurea receptor (SUR1, SUR2A, and SUR2B). The Kir6.0 sub...

The role of KATP channels in cerebral ischemic stroke and diabetes.
Abstract ATP-sensitive potassium (KATP) channels are ubiquitously expressed on the plasma membrane of cells in multiple organs, including the heart, pancreas and brain. KATP channels play important roles in controlling and regulating cellular functions in response to metabolic state, which are inhibited by ATP and activated by Mg-ADP, allowing the cell to couple cellular metabolic state (ATP/ADP ratio) to electrical activity of the cell membrane. KATP channels mediate insulin secretion in pancreatic islet beta cells, and controlling vascular tone. Under pathophysiological conditions, KATP channels play cytoprotect...
