The nematode Caenorhabditis elegans is well established as a system for characterization and discovery of molecular mechanisms mediating microbe-specific inducible innate immune responses to human pathogens. Coxiella burnetii is an obligate intracellular bacterium that causes a flu-like syndrome in humans (Q fever), as well as abortions in domesticated livestock, worldwide. Initially, when wild type C. elegans (N2 strain) was exposed to mCherry-expressing C. burnetii (CCB) a number of overt pathological manifestations resulted, including intestinal distension, deformed anal region and a decreased lifespan...

Drug-induced parkinsonism (DIP) is classically described as acute/subacute, bilateral symmetric syndrome in which tremor is infrequent compared to Parkinson's disease. Most DIP cases are caused by classic (CN) and second-generation neuroleptics (SN), and calcium channel blockers (CCB). We evaluated potentially distinctive demographic and clinical features in DIP among different drug classes. This was a prospective study of reversible DIP related to single selected drugs on each class. Baseline assessment included demographic, clinical data, and scales for staging, severity of motor signs of parkinsonism, tremor, and other involuntary movements...

BACKGROUND: Vascular access failure is a huge burden for patients undergoing hemodialysis. Many efforts have been made to maintain vascular access patency, including pharmacotherapy. Angiotensin converting enzyme inhibitor (ACE-I), angiotensin receptor blocker (ARB), and calcium channel blocker (CCB) are known for their antihypertensive and cardio-protective effects, however, their effects on long-term vascular access patency are still inconclusive. DESIGN, SETTING, PARTICIPANTS AND MEASUREMENTS: We retrospectively enrolled patients commencing maintenance hemodialysis between January 1, 2000, and December 31, 2006 by using National Health Insurance Research Database in Taiwan...

INTRODUCTION/PURPOSE: To achieve aneurysm occlusion, flow diverters (FDs) must be accurately sized to maximize coverage over the neck and induce thrombosis. Catheterization for diagnostic angiography can cause vasospasm that may affect vessel measurements. This study evaluates impacts of intra-arterial infusion of a calcium channel blocker (CCB) on angiographic measurements in patients treated with FDs to determine effects on final diameter of the FD and subsequent occlusion. MATERIALS AND METHODS: Pre-treatment measurements were recorded for diameter of the distal and proximal landing zones and maximum and minimum diameters between these segments...

Hypertension is associated with alterations in the vascular structure, which in turn enhance the risk of cardiovascular events. Notably, anti-hypertensive treatment may prevent or regress the changes of arterial wall structures. Lercanidipine is a third-generation CCB with peculiar pharmaceutical properties. Enalapril is an effective drug acting on the renin-angiotensin-aldosterone axis. This commentary discusses the vascular effects of the lercanidipine/enalapril combination, and comments on their potential clinical relevance...

Koi herpesvirus (KHV) is highly pathogenic to Cyprinus carpio. KHV can also become latent in recovered fish and reactivate from latency under stressful conditions. Understanding KHV latency is important for development of strategies against herpesvirus latent infection. Our previous studies found KHV ORF6 mRNA is detectable during latent infection. In this study, ORF6 protein expression was investigated by a polyclonal antibody specific to ORF6 peptide. Positive staining by an immunofluorescence assay was observed in both KHV infected CCB (common carp brain) cells and IgM(+) white blood cells (WBCs) from recovered KHV(+) koi...

OBJECTIVE: Recently several studies reported that anti-hypertensive drugs were associated with development of new-onset diabetes mellitus (NODM). However, data on the relationship between detailed prescription types and long-term incidence of NODM are still limited in Asian patients (pts). DESIGN AND METHOD: A total of 3,208 consecutive hypertension pts prescribed with calcium channel blockers (CCB) were enrolled with the exclusion of diabetic pts. Pts were divided into two groups according to the additional prescription of renin angiotensin system (RAS) blockers; 1) the CCB group (n = 1,987) and 2) CCB + RAS group (n = 1,221)...

OBJECTIVE: In most cases, the 5 first line drugs are recommended for management of hypertension without preference for one or the other. However, it is unclear whether different classes of anti-hypertensive agents have different effect on survival in low risk, uncomplicated hypertension. The aim of this study was to evaluate effects of 4 classes of first line anti-hypertensive agents on improving survival in patients with low risk, uncomplicated hypertension. DESIGN AND METHOD: Adult hypertensive patients without chronic kidney disease, end stage renal disease, diabetes mellitus, acute coronary syndrome, and heart failure in 2002 were selected from Korean National Health Insurance sample cohort consisting of one million subjects...

There is accumulating evidence that RAS inhibitors not only reduce blood pressure, but also exert pleiotropic effects, including a renoprotective effect, amelioration of insulin resistance, reduction in onset of diabetes, and suppression of cardiovascular remodelling,. However, the definite benefit of RAS inhibition in treatment of hypertension with CKD or DM is not conclusive. We previously performed the OlmeSartan and Calcium Antagonists Randomized (OSCAR) study comparing the preventive effect of high-dose ARB therapy versus ARB plus CCB combination therapy on cardiovascular morbidity and mortality in 1164 Japanese elderly hypertensive patients with baseline type 2 diabetes and/or CVD (Am J Med (2012))...

Heart disease, stroke, and kidney failure are leading causes of death worldwide, and hypertension is a significant risk factor for each. Hypertension is less common in women, compared to men, in those younger than 45 years of age. This trend is reversed in those 65 years and older. In the US between 2011-2014, the prevalence of hypertension in women and men by age group was 6% vs 8% (18-39 years), 30% vs 35% (40-59 years), and 67% vs 63% (60 years and over). Awareness, treatment, and control rates differ between genders with women being more aware of their diagnosis (85% vs 80%), more likely to take their medications (81% vs 71%) and more frequently having controlled hypertension (55% vs 49%)...

Beginning with the Veterans Administration (VA) Cooperative Hypertension Study of the 1960 s, blood pressure (BP) lowering with antihypertensive medications has been shown to reduce major cardiovascular (CV) outcomes, including coronary heart disease, stroke, heart failure (HF) and CV and all-cause mortality in randomized controlled CV outcome trials. Multiple drugs were usually required in these trials to lower BP in treated participants. Medication regimens in the early trials, including the VA trial, included a thiazide-type diuretic (TTD) as initial therapy...

OBJECTIVE: It has been long believed that there is a close association between hypertension and atrial fibrillation (AF). However, there have been few studies on the impact of antihypertensive medication in hypertensives with AF. To investigate whether the timing of the antihypertensive drug administration influences blood pressure (BP) level and biomarkers to hypertensives with AF. DESIGN AND METHOD: The present study was a multicentered, prospective, randomized, open-labelled clinical trial to investigate the difference in the effect of telmisartan/amlodipine combination tablets on BP levels and BP variability using ambulatory BP monitoring (ABPM) and home BP between the morning administration and the bedtime administration in hypertensives with paroxysmal AF...

BACKGROUND: Calcium channel blockers (CCBs) may affect prostate cancer (PCa) growth by various mechanisms including those related to androgens. The fusion of the androgen-regulated gene TMPRSS2 and the oncogene ERG (TMPRSS2:ERG or T2E) is common in PCa, and prostate tumors that harbor the gene fusion are believed to represent a distinct disease subtype. We studied the association of CCB use with the risk of PCa, and molecular subtypes of PCa defined by T2E status. METHODS: Participants were residents of King County, Washington, recruited for population-based case-control studies (1993-1996 or 2002-2005)...

Hypertension is one of the most common conditions seen in primary care and a major public health problem in India. It can lead to various complications if not detected early and treated appropriately. As per the latest Eighth Joint National Committee (JNC 8) the goal BP in most hypertensive patients age <60 years should be <140/90 mmHg and treatment can be started by selecting drugs from among 4 specific medication classes i.e. angiotensin converting enzyme inhibitor (ACEI) or angiotensin receptor blocker (ARB), calcium channel blocker (CCB) or diuretics...
