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)...

WHAT IS KNOWN AND OBJECTIVE: Chylous ascites is a rare condition. The most frequent causes are lymphomas, solid malignancies, abdominal trauma and cirrhosis. Isolated case reports describe the relationship between calcium channel blockers (CCB) and chyloperitoneum. Lercanidipine is a third-generation dihydropyridine with low rate of adverse events. We describe a case of lercanidipine-induced chylous ascites. CASE SUMMARY: An 80-year-old white female with hypertension treated with lercanidipine, developed chylous ascites and abdominal pain after the dosage of the CCB was doubled...

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...

Metagenomics-based studies of mixed microbial communities are impacting biotechnology, life sciences and medicine. Computational binning of metagenomic data is a powerful approach for the culture-independent recovery of population-resolved genomic sequences, i.e. from individual or closely related, constituent microorganisms. Existing binning solutions often require a priori characterized reference genomes and/or dedicated compute resources. Extending currently available reference-independent binning tools, we developed the BusyBee Web server for the automated deconvolution of metagenomic data into population-level genomic bins using assembled contigs (Illumina) or long reads (Pacific Biosciences, Oxford Nanopore Technologies)...

Recently, blood pressure variability (BPV) has gained focus owing to its role in predicting cardiovascular (CV) outcomes. Additionally, alterations in BPV contribute to the progression of end organ damage and trigger vascular events in hypertensive patients. Therefore, amelioration of BPV is considered a potentially important target and different classes of drugs are used to achieve the desired blood pressure (BP) goal. Based on several studies and clinical trials, treatments with CCB such as amlodipine have been found to be most effective in the management of BPV in hypertensive patients with diabetes...

In patients with insufficient blood pressure (BP) control, despite using a combination regimen containing an angiotensin receptor blocker and a calcium channel blocker (CCB), whether a greater dose of CCB or adding a diuretic is more effective at lowering BP remains unclear. We conducted a multicenter randomized clinical trial to compare the efficacy of switching from the daily administration of a single-pill fixed-dose combination of irbesartan (100 mg) and amlodipine (5 mg) to irbesartan (100 mg) with an increased dose of amlodipine (10 mg) (HD group, n=62) or irbesartan (100 mg) and amlodipine (5 mg) with 1 mg of indapamide (D group, n=63) in patients with poorly controlled hypertension...

Although koi herpesvirus (KHV) has a history of causing severe economic losses in common carp and koi farms, there are still no treatments available on the market. Thus, the aim of this study was to test exopolysaccharides (EPS) for its antiviral activity against KHV, by monitoring inhibition and cytotoxic effects in common carp brain cells. These substances can be easily extracted from extracellular algae supernatant and were identified as groups of sulphated polysaccharides. In order to reach this aim, Arthrospira platensis, which is well known for its antiviral activity of intra- and extracellular compounds towards mammalian herpesviruses, was investigated as standard organism and compared to commercial antiviral drug, ganciclovir, which inhibits the viral DNA polymerization...

Menthol is a naturally occurring terpene used as a penetration enhancer in topical and transdermal formulations. Literature shows a growing interest in menthol's interactions with the transient receptor potential melastatin 8. A decrease in extracellular Ca(2+) due to the activation of the transient receptor potential melastatin 8 receptor produces inhibition of E-cadherin expression that is responsible for cell-cell adhesion. Because calcium is present in the entire epidermis, the purpose of this study is to evaluate whether the aforementioned properties of menthol are also related to its penetration-enhancing effects...

Objective: The mechanism of the beneficial effect of calcium channel blockers (CCBs), especially verapamil, on the development of type 2 diabetes mellitus (T2DM) has been described. Previous clinical studies aiming to confirm these results were flawed by inappropriate comparator drugs or study designs. This study compared the incidence of T2DM in adults prescribed oral verapamil and propensity score-matched adults prescribed other oral CCBs. Methods: This retrospective population-based cohort study used Taiwan's National Health Insurance Research Database during 2000-2011...

BACKGROUND: Left ventricular hypertrophy (LVH) is commonly present in patients with hypertension (HT). According to the expert consensus document from American, angiotensin-converting enzyme inhibitor (ACEI) and angiotensin receptor blockers (ARBs) were recommended as 1st-line therapeutic drugs. However, none noticed the different efficacy between fat-soluble and selective β1-receptor blockers (FS-β-B) and other β-blockers on regression of LVH before. The aim of this analysis was to compare the efficacy of FS-β-B with the other 4 different classes of antihypertensive drugs (ACEI, ARBs, calcium channel blockers [CCBs], and diuretics) on regression of LVH...
