Placental infiltration of inflammatory markers in gestational diabetic women.

2013

Gestational diabetes mellitus (GDM) is pathology of glucose intolerance during pregnancy. It is influenced by maternal hyperglycemia and insulinemia through placental circulation. The study was undertaken to investigate the implication of pro-inflammatory factors in the placenta of GDM women. Thirty GDM women have delivered macrosomic babies, and 30 healthy age-matched pregnant women have delivered non macrosomic babies, were recruited in the study. The mRNAs encoding for IL-6, TLR4, TGF-β, CD68, CD14, EMR-1, CCL2, TCR-α, T-bet, GATA-3, leptin and adiponectin were quantified in placental samples by using RT-qPCR. The mRNA expression of the pro-inflammatory factors, i.e., IL-6, TLR4 and TGF-…

Visual-motion suppression in congenital pendular nystagmus.

2009

Patients with a congenital pendular nystagmus are known not to experience oscillopsia in a normal visual environment. The data of a 31-year-old female patient suffering from a congenital pendular nystagmus are presented. The aim of the fluorodeoxyglucose positron emission tomography (FDG-PET) experiment was to analyze the regional cerebral glucose metabolism (rCGM) during minimal as well as maximal nystagmus. Video-oculography showed a maximum in frequency of the horizontal pendular nystagmus during gaze to the left, whereas the zone of minimal nystagmus was 10 degrees to the right. Two sessions with an 18F-fluorodeoxyglucose tracer were performed to analyze cerebral blood-glucose utilizati…

Serum Concentration of Growth Differentiation Factor-15 Is Independently Associated with Global Platelet Function and Higher Fibrinogen Values in Adu…

2017

AbstractGrowth differentiation factor-15 (GDF-15) has recently emerged as a strong and independent predictor of cardiovascular events and mortality. However, the pathophysiological mechanisms underlying this important association remain speculative. This study was aimed to investigate the potential associations between the serum concentration of GDF-15 and clinical or laboratory parameters in a population of ostensibly healthy subjects. The study population consisted of 44 healthy volunteers enrolled from the laboratory staff (14 males and 30 females; mean age, 47 ± 11 years), who had their blood collected for assessing complete blood cell count, GDF-15, serum creatinine, albumin, cardiac t…

Anatomical correlates of ocular motor deficits in cerebellar lesions

2009

Humans are able to stabilize the images of moving targets on the retina by means of smooth pursuit eye movements. After the pontine level, all smooth pursuit pathways pass through the cerebellum. Previous animal studies gave evidence that two specific lesion sites within the cerebellum cause smooth pursuit disorders: those of the flocculus/paraflocculus and the vermis including lobule VI, VII, the uvula and the deep cerebellar nuclei. To date, there have been only a few lesion studies in patients with smooth pursuit disorders that do not allow direct comparison with a control group. In the present study, new lesion mapping techniques determined which cerebellar structures were involved in p…

Inhibition of dextromethorphan metabolism by moclobemide.

1998

This pilot study was conducted to evaluate the potential of the new antidepressant moclobemide to inhibit the cytochrome enzyme P4502D6 (CYP2D6) using the cough suppressant dextromethorphan as a substrate in four extensive metabolizers (EM) of debrisoquine. The subjects received seven oral doses of 20 mg dextromethorphan at 4-h intervals over 2 days (1 and 2) and subsequently moclobemide (300 mg b.i.d.) for 9 days. On days 10 and 11, they received seven doses of 20 mg dextromethorphan in addition to moclobemide. During monotreatment and combined treatment, blood was collected on days 2 and 11, respectively, for determination of dextromethorphan and its demethylated metabolites using automat…

Expression of adhesion factors and degrading proteins in primary and secondary glioblastomas and their precursor tumors.

2000

In tumor tissue specimens of 27 primary and 17 secondary glioblastomas and the precursor lesions, the immunohistochemical expression patterns of the membrane protein CD44s, the basal lamina proteins laminin, collagen IV, and fibronectin, the lectin galectin-3 recognizing tenascin and N-CAM as well as of the matrix-degrading enzymes matrix metalloproteinase MMP-2 and MMP-9, and cathepsin D were studied. Besides expression of basal lamina proteins in vessels, all glioblastomas and the precursor lesions showed strong immunoreactivity of CD44s, tenascin, galectin-3, and N-CAM which were restricted to solid tumor masses. Present in solid tumor areas, MMP-2, MMP-9 and cathepsin D were also strong…

Survival After Transplantation of Corneas From a Rabies-Infected Donor

2011

To examine the tissue samples of 2 corneal recipients from a rabies-infected donor for the presence of rabies to explain their survival.Interventional case series with a review of the literature. The explanted corneal donor buttons were examined via nested reverse transcriptase polymerase chain reaction. The patients were followed up ophthalmologically and neurologically. Antirabies antibodies were measured in blood samples, and skin biopsies were examined by direct fluorescent antibody staining.Two patients received corneas from the same multiorgan donor. Six weeks after transplantation, 3 of the donor's organ recipients became symptomatic and rabies virus was confirmed in tissue from the …

Spontaneous Resolution of Delayed Suprachoroidal Hemorrhage in the Single Eye Following Needling in Congenital Glaucoma

2017

Suprachoroidal hemorrhage (SCH) is a rare, but potentially vision-threatening event with poor long-term visual prognosis. At present, there is disagreement whether surgical intervention or conservative treatment is superior in the management. We report on a case of spontaneous resolution of severe SCH after needling procedure in the only eye of a young patient with congenital glaucoma.A 43-year-old woman with congenital glaucoma was scheduled for bleb needling in her only eye. Preoperative best-corrected visual acuity was 20/40 and intraocular pressure 20 mm Hg. On the third postoperative day, she developed a massive delayed SCH with appositional (kissing) choroidal bullae and visual acuity…

Use of complementary and alternative medicine: A multicenter cross-sectional study in 1089 melanoma patients.

2016

Abstract Background About half of patients with cancer use complementary and alternative medicine (CAM). So far, data on melanoma patients are missing. Objective The aim of our study was to evaluate the prevalence and predictors for the use of CAM in this patient group. Methods All patients with melanoma being attended at one of 7 skin cancer centres in Germany between March 2012 and March 2013 were invited to take part in a survey using a structured questionnaire on CAM. The physicians filled in a second part on the diagnosis, state and former and current therapy. Results Nearly half of the 1089 participants (41.0%) used CAM and half of those using CAM (56.8%) marked that this made them fe…

2012

AIMS: To evaluate the visual performance of an aberration-free intraocular lens (IOL) in patients with different corneal profiles using adaptive optics visual simulation. METHODS: A crx1 adaptive optics visual simulator was used to simulate the aberration pattern of an aberration-free IOL combined with five corneal profiles: virgin corneas and corneas with low and high myopic ablations and low and high hyperopic ablations. Ten eyes of 10 subjects were evaluated, and monocular distance visual acuity (VA) at 100%, 50% and 10% of contrast was measured. RESULTS: At 100% of contrast, no differences were found in VA values among virgin corneas, low and high myopic ablations and low hyperopic abla…
