Calcium channel blockers (CCBs) are responsible for a substantial portion of the mortality associated with cardiovascular medication overdose cases. Amlodipine, a dihydropyridine CCB, can cause prolonged hypotension in overdose. This report describes a severe amlodipine overdose case that was refractory to multiple therapeutic approaches. A 53-year-old male presented after ingesting eighty 10 mg amlodipine tablets in a suicide attempt. The patient was initially managed with calcium boluses, glucagon, multiple vasoactive agents, lipid emulsion infusions and hyperinsulinemic euglycemic therapy...

BACKGROUND: Little is known about the treatments physicians choose for themselves compared with how they treat their patients. We determine if physicians prescribe different treatments to patients than to themselves. METHODS: Population-based cohort study from 2004 to 2012 examining prescription claims of all Danish primary care physicians (PCP; n=3088) and all other Danish adults (n=2 334 590) who received a first-time prescription from a PCP for a statin (n=455 586), calcium channel blocker (CCB, n=330 369), serotonin-norepinephrine/selective serotonin reuptake inhibitors (SN/SSRIs, n=423 740), proton pump inhibitor (PPI, n=671 965) or antihistamine (n=456 018)...

Four slow pyrolyzed biochars produced from wood (WDB), corncobs (CCB), rice husks (RHB) and sawdust (SDB) were evaluated for adsorption, desorption and regeneration of phosphate (PO4(3-)-P) from anaerobically digested liquid swine manure. The PO4(3-)-P adsorption capacity increased followed by initial concentrations increasing. Maximum PO4(3-)-P adsorptions at initial 150 mg/L of PO4(3-)-P (highest load) were average of 7.67, 6.43, 5.73 and 5.41 mg/g for WDB, CCB, RHB and SDB, respectively. Pseudo second order kinetics model could best fit PO4(3-)-P adsorption, which indicated the chemisorption via precipitation was the main mechanism for PO4(3-)-P removal...

INTRODUCTION: Hypertension is a major health issue worldwide. Calcium Channel Blockers (CCBs) are the most commonly used antihypertensive agents. CCBs act on voltage-dependent calcium channels and they were categorized into two subclasses, Dihydropyridine (DHP) and non-Dihydropyridine (non-DHP) derivative. Amlodipine is a third generation L-type of DHP and Cilnidipine is a novel L/N-type of DHP CCB, both drugs have excellent pharmacological profiles with the unique actions. AIM: To study the clinical and biochemical profile in Amlodipine and Cilnidipine treated mild to moderate hypertensive patients...

Research of cyprinid herpesvirus 3 (CyHV-3) is focused on the infection mechanism and disease development in animals using genetic and immunological approaches to improve treatments and diagnostics. In contrast, only few tried to investigate the CyHV-3 replication behaviour in available cell cultures. Whereas, obtaining high virus yields by in vitro replication enables achieving of the mentioned above goals easier and more reliable. The following work presents an attempt to illuminate the KHV replication in common carp brain (CCB) cell cultures from the engineering point of view...

Non-dihydropyridine calcium channel blockers (non-DHP CCBs) possess combined P-glycoprotein and moderate CYP3A4 inhibition, which may lead to increased exposure of medications that are substrates for these metabolic pathways, such as rivaroxaban. We evaluated the use and outcomes of non-DHP CCBs in patients with atrial fibrillation (AF) in Rivaroxaban Once Daily Oral Direct Factor Xa Inhibition Compared with Vitamin K Antagonism for Prevention of Stroke and Embolism Trial in Atrial Fibrillation (ROCKET AF)...

Nutrient availability and ratios can play an important role in shaping microbial communities of freshwater ecosystems. The Cuatro Ciénegas Basin (CCB) in Mexico is a desert oasis where, perhaps paradoxically, high microbial diversity coincides with extreme oligotrophy. To better understand the effects of nutrients on microbial communities in CCB, a mesocosm experiment was implemented in a stoichiometrically imbalanced pond, Lagunita, which has an average TN:TP ratio of 122 (atomic). The experiment had four treatments, each with five spatial replicates - unamended controls and three fertilization treatments with different nitrogen:phosphorus (N:P) regimes (P only, N:P = 16 and N:P = 75 by atoms)...

Théophile Godfraind
In the mid 1960s, experimental work on molecules under screening as coronary dilators allowed the discovery of the mechanism of calcium entry blockade by drugs later named calcium channel blockers. This paper summarizes scientific research on these small molecules interacting directly with L-type voltage-operated calcium channels. It also reports on experimental approaches translated into understanding of their therapeutic actions. The importance of calcium in muscle contraction was discovered by Sidney Ringer who reported this fact in 1883...

Pharmacotherapeutic options for pulmonary arterial hypertension (PAH) have increased dramatically in the last two decades and along with this have been substantial improvements in survival. Despite these advances, however, PAH remains a progressive and ultimately fatal disease for most patients and only epoprostenol has been shown to improve survival in a randomized control trial. Clinical observations of the heterogeneity of treatment response to different classes of medications across the phenotypically diverse PAH population has led to the identification of patients who derive significantly more benefit from certain medications than the population mean, the so-called "super responders...

Bacteria have numerous strategies to interact with them and with their environment. However, genes associated with these interactions are usually cataloged as pathogenic. To understand the role that these genes have not only in pathogenesis but also in bacterial interactions, we compared the genomes of eight bacteria from human-impacted environments with free-living bacteria from the Cuatro Ciénegas Basin (CCB), a relatively pristine oligotrophic site. Fifty-one genomes from CCB bacteria, including Pseudomonas, Vibrio, Photobacterium, and Aeromonas were analyzed...

INTRODUCTION: An ischemic stroke is an event that occurs due to cerebral vascular disease and is directly related to the degree of vascular damage. This process is associated with atherosclerosis progression and is influenced by the presence of cardiovascular risk factors. AIMS: One of the goals of our research was to examine whether specific medications used for treating hypertension are associated with the development of strokes. METHODS: In a retrospective study of patients who were hospitalized between the years 2003-2008 due to a cerebrovascular accident (CVA) or a transient ischemic attack (TIA), 916 cases of stroke patients were reviewed...

BACKGROUND: The optimal therapy in patients with heart failure preserved ejection fraction (HFpEF) and hypertension (HT) has not been revealed. The beta blocker (BB) and the renin angiotensin aldosterone system inhibitor (RAAS-I) are recommend as class IIa in patients with HFpEF. The calcium channel blocker (CCB), a major anti-hypertensive drugs in Japan, is also recommend as class IIa in patients with HFpEF. However, the difference between azelnidipine, an L type CCB, and cilnidipine, an N type CCB, is unclear...

A 64-year-old man visited our hospital with complaints of misty vision and ophthalmalgia. On admission, his blood pressure (BP) was high at 220/135 mmHg with no past history of hypertension, and he had choked discs. He was tentatively diagnosed as having idiopathic intracranial hypertension, and was later found to have atherosclerotic unilateral renovascular hypertension (RVH) based upon the extremely high plasma renin activity together with the radiological image tests. On day 3, combined antihypertensive therapies consisting of oral angiotensin II receptor blocker (ARB) and Ca channel blocker (CCB) along with intravenous CCB induced an abrupt BP lowering which led to deterioration of his renal function, progressing into acute kidney injury (AKI)...

The phylum Actinobacteria constitutes one of the largest and anciently divergent phyla within the Bacteria domain. Actinobacterial diversity has been thoroughly researched in various environments due to its unique biotechnological potential. Such studies have focused mostly on soil communities, but more recently marine and extreme environments have also been explored, finding rare taxa and demonstrating dispersal limitation and biogeographic patterns for Streptomyces. To test the distribution of Actinobacteria populations on a small scale, we chose the extremely oligotrophic and biodiverse Cuatro Cienegas Basin (CCB), an endangered oasis in the Chihuahuan desert to assess the diversity and uniqueness of Actinobacteria in the Churince System with a culture-dependent approach over a period of three years, using nine selective media...
