The Effects of an Essential Oil and an Amine Fluoride/Stannous Fluoride Mouthrinse on Supragingival Plaque Regrowth
2008
Background: The side effects of chlorhexidine (CHX) have stimulated the search for alternative antiplaque agents such as amine fluoride/stannous fluoride (ASF) and essential oils (EO). The aim of the study was to investigate the plaqueinhibiting effects of two commercially available mouthrinses containing ASF and EO, respectively. Methods: The study was an observer-masked, randomized, 5 · 5 Latin square cross-over design, balanced for carryover effects, involving 15 volunteers in a 4-day plaque regrowth model. A 0.12% CHX rinse and a saline solution served as positive and negative controls, respectively. On day 1, subjects received professional prophylaxis, suspended oral hygiene measures, …
High-dose short-term administration of naringin did not alter talinolol pharmacokinetics in humans.
2015
Naringin is considered the major causative ingredient of the inhibition of intestinal drug uptake by grapefruit juice. Moreover, it is contained in highly dosed nutraceuticals available on the market. A controlled, open, randomized, crossover study was performed in 10 healthy volunteers to investigate the effect of high-dose naringin on the bioavailability of talinolol, a substrate of intestinal organic anion-transporting polypeptide (OATP)-mediated uptake. Following 6-day supplementation with 3 capsules of 350 mg naringin daily, 100mg talinolol were administered orally with 3 capsules of the same dietary supplement (1050 mg naringin) on the seventh day. This test treatment was compared to …
Ten novel mutations found in Aniridia.
1998
Aniridia (AN) is a sight-threatening congenital ocular disorder characterized by iris hypoplasia, corneal pannus, foveal and optic nerve hypoplasia, cataract formation, and glaucoma. In two-thirds of the patients, AN is inherited in an autosomal dominant fashion with almost complete penetrance but variable expression. The remaining cases are sporadic. Aniridia has been shown to be associated with mutations in the PAX6 gene, located on chromosome 11p13, telomeric to the Wilms' tumor predisposition gene (WT1). This paper describes 14 mutations in the PAX6 gene in patients with AN. Among these 14 mutations, 10 have been unpublished until now. They result most probably in haploinsufficiency and…
Characterization of Small Incidental Indeterminate Hypoattenuating Hepatic Lesions: Added Value of Single-Phase Contrast-Enhanced Dual-Energy CT Mate…
2018
OBJECTIVE. The objective of this study is to determine whether single-phase contrast-enhanced dual-energy CT (DECT) material attenuation analysis improves the characterization of small (< 2.0 cm) incidental indeterminate hypoattenuating hepatic lesions, compared with conventional single-energy CT evaluation. MATERIALS AND METHODS. This retrospective study involved 55 patients (24 men and 31 women; mean [± SD] age, 63.9 ± 15.3 years) with 77 incidental hypoattenuating hepatic lesions (59 benign and 18 malignant lesions) measuring 0.5–2.0 cm who underwent single-phase contrast-enhanced DECT of the abdomen for pain. For each lesion, attenuation measurements were obtained using blended 120-k…
Allelic variants of IL1R1gene associate with severe hand osteoarthritis
2010
Background In search for genes predisposing to osteoarthritis (OA), several genome wide scans have provided evidence for linkage on 2q. In this study we targeted a 470 kb region on 2q11.2 presenting the locus with most evidence for linkage to severe OA of distal interphalangeal joints (DIP) in our genome wide scan families. Methods We genotyped 32 single nucleotide polymorphisms (SNPs) in this 470 kb region comprising six genes belonging to the interleukin 1 superfamily and monitored for association with individual SNPs and SNP haplotypes among severe familial hand OA cases (material extended from our previous linkage study; n = 134), unrelated end-stage bilateral primary knee OA cases (n =…
More than a leap of faith: the impact of biological and religious correlates on reproductive behavior.
2004
Using a conceptual model that integrates both social and biomedical factors of causation, this paper tries to delineate the pathways through which the reproductive characteristics of a multidenominational community are characterized. In total, 5513 historical entries from family reconstitution were available. Selection of data was guided by the inclusion of information about religious affiliation. Only married couples with children as well as single mothers with the relevant information were considered. Of these, 1855 entries were of Roman Catholic (C), 1143 of Lutheran/Protestant (L/P2), and 609 of Reformed Calvinist (R) denomination. The analysis documented differential nuptiality and fer…
Role of proinflammatory alleles in longevity and atherosclerosis: results of studies performed on -1562C/T MMP-9 in centenarians and myocardial infar…
2007
Centenarians are characterized by marked delay or escape from age-associated diseases that cause mortality at earlier ages. Jointly, atherosclerosis and its complications, such as myocardial infarction (AMI), significantly contribute to mortality in the elderly. Inflammation is a key component of atherosclerosis and inflammatory genes are good candidates for the risk of the development of atherosclerosis. Genetic traits contribute to the risk of AMI and allelic variations in inflammatory genes should boost the risk of disease. If proinflammatory genotypes significantly contribute to the risk of AMI, alleles associated with disease susceptibility should not be included in the genetic backgro…
God, Faith, and Death: The Impact of Biological and Religious Correlates on Mortality
2004
Marked denominational mortality differentials have been documented for various time periods and geographic locations. From a historical perspective, death rates among Catholics are often found to be higher than those among Protestants or Jews. Using a conceptual model based on the life history approach, biomedical and sociocultural factors of causation are extrapolated. In total, 5513 historical entries from family reconstitution were available. Selection of data was guided by the inclusion of information about religious affiliation. Only married couples with children as well as single mothers were considered. Of these, 1855 entries were of Roman Catholic (C), 1143 of Lutheran/Protestant (L…
Influence of CYP3A5 and ABCB1 gene polymorphisms and other factors on tacrolimus dosing in Caucasian liver and kidney transplant patients
2011
Tacrolimus is a substrate of cytochrome P4503A (CYP3A) enzymes as well as of the drug transporter ABCB1. We have investigated the possible influence of CYP3A5 and ABCB1 single nucleotide polymorphisms (SNPs) and other factors (e.g. albumin, hematocrit and steroids) on tacrolimus blood levels achieved in a population of Caucasian liver (n=51) and kidney (n=50) transplant recipients. At 1, 3 and 6 months after transplantation, tacrolimus doses (mg/kg/day) and trough blood levels (C0) were recorded and the weight-adjusted tacrolimus dosage (mg/kg/day) was calculated. Polymerase chain reaction followed by restriction fragment length polymorphism analysis was used for genotyping CYP3A5*1 and *3 …
Pseudoachalasia: a case series and analysis of the literature.
2005
Pseudoachalasia frequently cannot be distinguished from idiopathic achalasia by manometry, radiologic examination or endoscopy. Mechanisms proposed to explain the clinical features of pseudoachalasia include a circumferential mechanical obstruction of the distal esophagus or a malignant infiltration of inhibitory neurons within the myenteric plexus.Between January 1980 and December 2002, the clinical features of 5 patients with pseudoachalasia and 174 patients with primary achalasia, diagnosed in a single center, were compared. A literature analysis of the etiology of pseudoachalasia for the time period 1968 to December 2002 was performed. The search concentrated on the databases and online…
