Metal ion chelation enhances tissue plasminogen activator (tPA)-induced thrombolysis: an in vitro and in vivo study
AbstractStroke is the third leading cause of death in the United States and the leading cause of adult disability. Despite enormous research efforts including many clinical trials, tissue plasminogen activator (tPA) remains the only FDA-approved treatment for acute ischemic stroke. Unfortunately, only 1 –3% of stroke patients in the US receive this therapy because of the narrow time window and severe side effects for using tPA. The most deadly and damaging side effect is the risk of intracranial bleeding or hemorrhage. For that reason, the dose of tPA and its overall administration are under tigh t control, which may com...

Sirt1 regulates microglial activation and inflammation following oxygen-glucose deprivation/reoxygenation injury by targeting the Shh/Gli-1 signaling pathway
CONCLUSION: These findings suggested that Sirt1 may regulate microglial activation and inflammation by targeting the Shh/Gli-1 signaling pathway following OGD/R injury. Schematic representation of Sirt1 regulating the microglial activation and inflammation following oxygen-glucose deprivation/reoxygenation injury via mediation of Shh/Gli-1 signaling pathway.PMID:36725745 | DOI:10.1007/s11033-022-08167-6

Zinc for infection prevention in children with sickle cell anemia: a randomized double-blind placebo-controlled trial
Blood Adv. 2023 Feb 3:bloodadvances.2022008539. doi: 10.1182/bloodadvances.2022008539. Online ahead of print.ABSTRACTData from small clinical trials in the USA and India suggest zinc supplementation reduces infection in adolescents and adults with sickle cell anemia (SCA), but no studies of zinc supplementation for infection prevention have been conducted in young children with SCA living in Africa, who have higher infection rates. We conducted a randomized double-blind placebo-controlled trial to assess the effectiveness of zinc supplementation for prevention of severe or invasive infections in Ugandan children 1.00-4.99 ...

Billions With Nutrition Deficiency!?
Almost no one gets enough selenium. Officially, at least a billion — with a B — people have a selenium deficiency.1 But I suspect the numbers are much higher than that. You can’t get enough selenium from food alone anymore. That’s true even if you eat a healthy, varied diet. And you can thank Big Agra for that. With their harsh pesticides, synthetic fertilizers, and single-crop strategy, these massive farms have stripped the nutrients out of the soil. No nutrients in the soil mean no nutrients in the food. All of this makes it difficult — if not impossible — to get even some of the daily selenium you need to ...

Fast Heartburn Relief Without Deadly Drugs
Since gastroesophageal reflux disease (GERD) was first identified in the early 1930s, the number of people experiencing heartburn has increased substantially. In fact, one study shows that in just 10 years, the number of people experiencing:1 Any GERD symptoms increased by 30% Symptoms at least once a week increased by 47% Severe GERD increased by 24% While these numbers are concerning, I’ll admit they’re not surprising considering the typical American diet. Our nutrition-less, grain-based diet of carbohydrates and starches has wrecked our health and made our bodies behave in ways nature never intended. This has led ...

Zinc Promotes the Death of Hypoxic Astrocytes by Upregulating Hypoxia-Induced Hypoxia-Inducible Factor-1alpha Expression via Poly(ADP-ribose) Polymerase-1.
CONCLUSIONS: Our studies show that zinc promotes hypoxic cell death through overexpression of the hypoxia response factor HIF-1α via the cell fate determine factor PARP-1 modification, which provides a novel mechanism for zinc-mediated ischemic brain injury.

Chelating Intracellularly Accumulated Zinc Decreased Ischemic Brain Injury Through Reducing Neuronal Apoptotic Death Basic Sciences
Conclusions— Ischemia-induced high accumulation of intracellular zinc significantly contributed to ischemic brain damage through promotion of neuronal apoptotic death. Removing zinc may be an effective and novel approach to reduce ischemic brain injury.

MicroRNAs Mediated MMP Regulation: Current Diagnostic and Therapeutic Strategies for Metabolic Syndrome.
Abstract Metabolic syndrome (MS) is a global socioeconomic problem rapidly progressing in accordance with increasing body mass index (BMI) and age. It is a consortium of risk factors, such as dyslipidaemia, insulin resistance, leptin resistance, reduced adiponectin, glucose intolerance, hyperglycemia, and hypertension. Collectively, these factors accelerate the onset of type 2 diabetes mellitus, cardiovascular disease, stroke, and certain cancers such as breast, liver pancreatic, and colon cancer. Extracellular matrix (ECM) and basement membrane remodeling play a central role during pathogenesis of MS as they regu...

Molecular screening and analysis of novel therapeutic inhibitors against c-Jun N-terminal kinase
Abstractc-Jun N-terminal kinase is an important regulator, activating several transcription factors in response to proinflammatory cytokines, ultraviolet radiations, environmental stress, hypoxia and osmotic shock and is known to be reported a cause for many diseases, such as diabetes, cancer, inflammation, stroke, etc. In the present study, we aim to predict novel therapeutic leads against c-Jun N-terminal kinase-3 by employing structure based virtual screening in combination with various in silico toxicity filters. We screened ZINC database virtually using a known potent c-Jun N-terminal kinase inhibitor, SP600125, as re...

Endocrine Disruptors and Health Effects in Africa: A Call for Action
Conclusion: To address the many challenges posed by EDCs, we argue that Africans should take the lead in prioritization and evaluation of environmental hazards, including EDCs. We recommend the institution of education and training programs for chemical users, adoption of the precautionary principle, establishment of biomonitoring programs, and funding of community-based epidemiology and wildlife research programs led and funded by African institutes and private companies. https://doi.org/10.1289/EHP1774 Received: 16 February 2017 Revised: 22 May 2017 Accepted: 24 May 2017 Published: 22 August 2017 Address correspond...

Neurotoxicity of Zinc.
Abstract Zinc-induced neurotoxicity has been shown to play a role in neuronal damage and death associated with traumatic brain injury, stroke, seizures, and neurodegenerative diseases. During normal firing of "zinc-ergic" neurons, vesicular free zinc is released into the synaptic cleft where it modulates a number of postsynaptic neuronal receptors. However, excess zinc, released after injury or disease, leads to excitotoxic neuronal death. The mechanisms of zinc-mediated neurotoxicity appear to include not only neuronal signaling but also regulation of mitochondrial function and energy production, as well as other...
