Oral lichen planus after certolizumab pegol treatment in a patient with Crohn's disease

2011

Dear Sir , Lichen planus (LP) is a relatively uncommon inflammatory dermatosis of the mucocutaneous surfaces that can present with a variety of clinical manifestations and, most commonly, affecting middle-aged adults. The disease course may be short or chronic, although most cases may resolve after 1 month to 7 years. The real prevalence of LP is unknown, but is estimated to be 1% in the USA.1 The pathogenesis of LP is not entirely understood. In general, activated T lymphocytes are recruited to the dermal–epidermal junction and induce apoptosis in basal keratinocytes. Both CD4+ and CD8+ T lymphocytes are found in the lichenoid infiltrate of LP, with a predominance of the latter cell type b…

Purpose: Few large-scale population-based studies have adequately examined the relationships between steroid hormones, health status and physical fitness. The purpose of the study was to describe the relationship of serum basal endogenous steroid hormones (testosterone, TES; empirical free testosterone, EFT; cortisol, COR) and sex hormone-binding globulin (SHBG) to body composition, cardiovascular risk factors, and physical fitness in young healthy men. Methods: Male reservists (25±4 yrs, N=846) participated in the study. Basal TES, EFT, COR and SHBG were measured in morning fasted blood. Stepwise regression analyses were used to examine associations between individual hormones to four sepa…

Topography of somatostatin gene expression relative to molecular progenitor domains during ontogeny of the mouse hypothalamus

2010

The hypothalamus comprises alar, basal, and floor plate developmental compartments. Recent molecular data support a rostrocaudal subdivision into rostral (terminal) and caudal (peduncular) halves. In this context, the distribution of neuronal populations expressing somatostatin (Sst) mRNA was analyzed in the developing mouse hypothalamus, comparing with the expression pattern of the genes Orthopedia (Otp), Distal-less 5 (Dlx5), Sonic Hedgehog (Shh), and Nk2 homeobox 1 (Nkx2.1). At embryonic day 10.5 (E10.5), Sst mRNA was first detectable in the anterobasal nucleus, a Nkx2.1-, Shh-, and Otp-positive basal domain. By E13.5, nascent Sst expression was also related to two additional Otp-positiv…

Long-term function of porcine islets and single cells embedded in barium-alginate matrix.

1993

The influence of alginate-embedding on the maintenance of functioning and morphological integrity in long-term culture of isolated porcine islets and islet cells was studied. Free-floating islets and islet cells served for control. Function was tested after the 1st, 2nd and 4th week. Basal and glucose-stimulated insulin secretion of embedded islets decreased slightly, but significantly after the first week (from 4.39 +/- 0.64 to 2.87 +/- 0.47 at normal and from 11.96 +/- 1.44 to 4.76 +/- 0.78 microU pro 24 h pro islet at elevated glucose concentration, p < 0.05 and < 0.01, resp.) and remained unchanged thereafter. Glucose-stimulation resulted in significant increases in insulin secretion at…

Memory for time intervals is impaired in left hemi-Parkinson patients.

2004

The basal ganglia have been proposed as one of the neural correlates of timekeeping functions. Both encoding and memory retrieval components for time perception are impaired in Parkinson's disease (PD). The aim of our study was to investigate in hemi-Parkinsonian patients the existence of a specific alteration in memory for time depending on the affected side, to better understand the contribution of the left or right basal ganglia circuits in different components of time perception. Right and left hemi-PD patients performed a time reproduction task in which they were required to reproduce in the same session short (5 s) and long (15 s) time intervals, in off- and on-therapy condition. Whil…

Endokrinologische Vorhersage der Therapieansprechbarkeit depressiver Patienten auf Lofepramin

1979

In a pilot study of 15 depressive patients of the neurotic and endogenous type we could show that some neuroendocrinological parameters are apt to predict the thymoleptic efficacy of lofepramine. These parameters, which were measured with a simple global stimulation test (insulin hypoglycaemia combined with injection of TRH and LHRH), were as follows: high basal blood glucose; high hypoglycaemic blood glucose; high decrease of blood glucose in comparison to the basal level; low basal TSH; low increase of HGH and low increase of cortisol after hypoglycemia. A synopsis of these parameters allowed a correct classification of 14 out of 15 patients according to therapy response and therapy resis…

Simultaneous stimulation of growth hormone, adrenocorticotropin and cortisol with L‐dopa/L‐carbidopa and propranolol in children of short stature

2000

In 59 otherwise healthy children of short stature, the simultaneous response of growth hormone, cortisol and plasma adrenocorticotropin (ACTH) to L-dopa/L-carbidopa and propranolol at 45 and 90 min after administration were investigated. A growth hormone response of 10 microg/l or higher was considered positive. The definition of a positive cortisol response included either a hormone increase of at least 193 nmol/l or a peak hormone level of at least 497 nmol/l. The ACTH increase had to be fourfold above 11 pmol/l to be considered positive. In the 59 investigated children, the median basal growth hormone levels increased from 1.35 microg/l to 18.05 microg/l and 10.15 microg/l at 45 and 90 m…

Maintenance costs of male dominance and sexually antagonistic selection in the wild

2018

Variation in dominance status determines male mating and reproductive success, but natural selection for male dominance can be detrimental or antagonistic for female performance, and ultimately their fitness. Attaining and maintaining a high dominance status in a population of competing individuals is physiologically costly for males. But how male dominance status is mediated by maintenance energetics is currently not well understood, nor are the corresponding effects of male energetics on his sisters recognized. We conducted laboratory and field experiments on rodent populations to test whether selective breeding for male dominance status (dominant vs. subordinate breeding lines) antagonis…

Unrest at the Nevados de Chillán volcanic complex: a failed or yet to unfold magmatic eruption?

2018

Resuming erupting activity at volcanoes that have been long quiescent poses a significant challenge to hazard assessment, as it require assessment of whether the change in activity is an isolated event or the beginning of a new eruptive sequence. Such inception is often poorly characterised as quiescent volcanoes tend to be poorly equipped and not extensively monitored, especially with respect to gas geochemistry. Here, we report gas composition and flux measurements from a newly opened vent at the very onset of eruptive activity at the Nevados de Chillán volcanic complex (Chile) in January-February 2016. The molar proportions of H2O, CO2, SO2, H2S and H2 gases are found to be 98.4, 0.97, 0…
