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...

Highly efficient radiosynthesis and biological evaluation of 18Fsafinamide, a radiolabelled anti-parkinsonian drug for PET imaging
ChemMedChem. 2022 Sep 6. doi: 10.1002/cmdc.202200472. Online ahead of print.ABSTRACTAs an add-on drug approved for Parkinson's disease treatment, safinamide has multiple functions, such as selective and reversible monoamine oxidase-B inhibition, voltage-sensitive sodium/potassium channel blockage, and glutamate release inhibition. Meanwhile, safinamide shows tremendous therapeutic potential in the context of other central nervous system diseases (e.g., ischaemic stroke, amyotrophic lateral sclerosis, depression, etc.). In this work, [18F]safinamide, which is safinamide labelled by the positron-emitting radionuclide [18F]fl...

Loop Diuretics Inhibit Ischemia-Induced Intracellular Ca2+ Overload in Neurons via the Inhibition of Voltage-Gated Ca2+ and Na+ Channels
One consequence of ischemic stroke is disruption of intracellular ionic homeostasis. Intracellular overload of both Na+ and Ca2+ has been linked to neuronal death in this pathophysiological state. The etiology of ionic imbalances resulting from stroke-induced ischemia and acidosis includes the dysregulation of multiple plasma membrane transport proteins, such as increased activity of sodium-potassium-chloride cotransporter-1 (NKCC-1). Experiments using NKCC1 antagonists, bumetanide (BMN) and ethacrynic acid (EA), were carried out to determine if inhibition of this cotransporter affects Na+ and Ca2+ overload observed follow...

Janssen Announces U.S. FDA Approval of INVEGA HAFYERA ™(6-month paliperidone palmitate), First and Only Twice-Yearly Treatment for Adults with Schizophrenia
TITUSVILLE, N.J., Sept. 1, 2021 – The Janssen Pharmaceutical Companies of Johnson & Johnson today announced the U.S. Food and Drug Administration (FDA) has approved long-acting atypical antipsychotic INVEGA HAFYERA™ (6-month paliperidone palmitate), the first-and-only twice-yearly injectable for the treatment of schizophrenia in adults. Before transitioning to INVEGA HAFYERA™, patients must be adequately treated with INVEGA SUSTENNA® (1-month paliperidone palmitate) for at least four months, or INVEGA TRINZA® (3-month paliperidone palmitate) for at least one 3-month injection cycle.1 The FDA approval of INVEGA ...

Interleukin-18 from neurons and microglia mediates depressive behaviors in mice with post-stroke depression.
In this study, we demonstrate that in IL-18 level in the ischemic brain significantly increased in mice with depression-like behaviors that caused by the combined use of chronic spatial restraint stress and middle cerebral artery occlusion. Interestingly, IL-18 expression was mainly found in neurons at early phase and in microglia in late phase. Injection of exogenous IL-18 in to the amygdala, but not the hippocampus or the striatum, caused severe depression-like behaviors. On the contrary, the blockage of endogenous IL-18 by IL-18 binding protein, a specific antagonist of IL-18, rescued depressive phenotypes in SIR mice. ...

Chemogenetics-mediated acute inhibition of excitatory neuronal activity improves stroke outcome.
CONCLUSIONS: Our data demonstrate that acute inhibition of a subset of excitatory neurons after ischemic stroke can prevent brain injury and improve functional outcome. This study, together with the previous work in optogenetic neuronal modulation during the chronic phase of stroke, supports the notion that targeting neuronal activity is a promising strategy in stroke therapy.

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...

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 ...

The effects of cerebral curvature on cortical spreading depression
In this study a large scale numerical NVC model of multiple NVUs is coupled to a vascular tree simulating a two-dimensional cerebral tissue slice. This model is extended with a spatial Gaussian curvature mapping that can simulate the highly folded nature of the human cortex. For a flat surface comparable to a lissencephalic cortex the model can simulate propagating waves of high extracellular K+ travelling radially outwards from a stimulated area at approximately 6.7 mm/min, corresponding well with multiple experimental results. The high K+ concentration induces a corresponding wave of vasoconstriction (with decreased bloo...

Potassium 2-(1-hydroxypentyl)-benzoate improves depressive-like behaviors in rat model
In this study, we demonstrated that PHPB improved depressive-like behaviors induced by chronic unpredictable mild stress (CUMS) in rats. Male SD rats were subjected to the stress for five weeks. PHPB (30 and 100 mg/kg) or fluoxetine (FLX 10 mg/kg, as positive control) was administered orally from the third week in CUMS procedure. The behavioral tests were applied and then the biochemical studies were carried out. PHPB or FLX treatment rescued the behavioral deficiency in CUMS-exposed rats. Meanwhile, PHPB normalized the enhanced level of serum corticosterone, improved hippocampal and serum BDNF levels, as well as...
