Immunoglobulin A response to acute stress in intimate partner violence perpetrators: the role of anger expression-out and testosterone.
2014
Aggressive behavior and immune activity are shown to be positively associated in perpetrators of intimate partner violence (IPV). This relationship follows an inverted-U curve, with the most violent individuals showing lower levels of immunocompetence than those with a history of moderate violence. Moreover, the activational and organizational effects of testosterone (T) may indirectly stimulate the immune response. Given this, we used the Trier Social Stress Test to establish whether the salivary immunoglobulin A (sIgA) response to acute stress was a specific psychobiological feature in perpetrators of intimate partner violence (IPV). IPV perpetrators showed higher sIgA levels than control…
Skin conductance rises in preparation and recovery to psychosocial stress and its relationship with impulsivity and testosterone in intimate partner …
2013
Intimate partner violence (IPV) perpetrators were categorized into 2 groups using Gottman et al.'s (1995) typology depending on their skin conductance (SC) reactivity to stress. Overall, type I perpetrators tend to show autonomic underarousal, whereas type II perpetrators present a preparatory hyperreactivity to confront stress. Moreover, impulsivity traits and testosterone (T) levels may modulate SC responses to increase the risk of proneness to violence. In this study, SC response to stress was assessed by comparing IPV perpetrators with non-violent controls while performing a modified version of the Trier Social Stress Test (TSST). Subjects with a history of IPV demonstrated higher non-s…
Inward currents in primary nociceptive neurons of the rat and pain sensations in humans elicited by infrared diode laser pulses
2002
Radiant heat is often used to study nociception in vivo. We now used infrared radiation generated by a diode laser stimulator (wavelength 980 nm) to investigate transduction mechanisms for noxious heat stimuli in acutely dissociated dorsal root ganglion (DRG) neurons of rats in vitro. The laser stimulator offered the unique opportunity to test whether the same stimuli also elicit pain sensations in humans. A specific heat-induced current (I(heat)) was elicited in six of 13 small DRG neurons (diameteror =30 microm) tested in the whole-cell configuration of the patch-clamp mode. Current responses in the seven heat-insensitive neurons were within the range explainable by the temperature depend…
Validation of the German version of the ‘Hypogonadism Related Symptom Scale’ (HRS) in andrological patients with infertility, HIV infection and metab…
2013
Summary As commonly used self-reported screening instruments for male hypogonadism demonstrated lack of specificity, a Hypogonadism Related Symptom Scale (HRS) was developed in 2009 as a novel self-rating screening tool. As the questionnaire has not been validated, the purpose of our study was to perform a validation in patients presenting with different disorders (e.g. infertility, HIV infection or metabolic syndrome) and disease-related risk to develop hypogonadism. Two hundred and eighteen patients aged 19–71 years (40.1 ± 9.5) who completed the HRS and other common questionnaires [International Index Of Erectile Function (IIEF), National Institutes of Health Chronic Prostatitis Symptom …
Human subcutaneous dirofilariasis, Russia
2007
We report 14 cases of human subcutaneous dirofilariasis caused by Dirofilaria repens, diagnosed from February 2003 through July 2004, in patients from Rostov-on-Don, Russia. Serologic analysis showed evidence of high risk of exposure to D. repens. Surveillance studies on prevalence and prevention effectiveness of canine infection are needed to control this emerging zoonosis.
Influence of Female Sex Hormones on Ultra-Running Performance and Post-Race Recovery: Role of Testosterone
2021
In recent years, increasing numbers of women have participated in extremely long races. In adult males, there is a clear association between physiological levels of endogenous sex hormones and physical performance. However, the influence of plasmatic sex hormones and the effects of different types of hormonal contraception (HC) on the modulation of physical performance in adult females remain to be fully clarified. Eighteen female ultra-endurance athletes were recruited to participate in the study. Different variables were studied, including hematological parameters, body mass index, and body composition. Strength measurements were obtained using the squat-jump and hand-grip test. A repeate…
Patch testing with components of water-based metalworking fluids: results of a multicentre study with a second series
2006
Background: Although many allergens in metalworking fluids (MWF) are identified, there are still some MWF components, which are not sufficiently investigated concerning their sensitizing properties. Objectives: To investigate sensitization to 10 frequently used MWF components, which are not part of the established MWF test series, in metalworkers with suspected occupational dermatitis due to MWF. Patients/Methods: Oleyl alcohol, myristyl alcohol, dimethylolurea, 4,4'-methylenebis morpholine, imazalil, 1-amino-2-propanol (monoisopropanolamine; MIPA), 2-amino-2-ethyl-1,3-propanediol (AEPD), 2,5-bis(n-octyldithio)-1,3,4-thiadiazole, zinc alkyl dithiophosphate and dibenzyl disulfide have been p…
Low testosterone levels are related to oxidative stress, mitochondrial dysfunction and altered subclinical atherosclerotic markers in type 2 diabetic…
2017
Abstract Introduction Low testosterone levels in men are associated with type 2 diabetes and cardiovascular risk. However, the role of testosterone in mitochondrial function and leukocyte-endothelium interactions is unknown. Our aim was to evaluate the relationship between testosterone levels, metabolic parameters, oxidative stress, mitochondrial function, inflammation and leukocyte-endothelium interactions in type 2 diabetic patients. Materials and methods The study was performed in 280 male type 2 diabetic patients and 50 control subjects. Anthropometric and metabolic parameters, testosterone levels, reactive oxygen species (ROS) production, mitochondrial membrane potential, TNFα, adhesio…
Hypogonadism-related symptoms: development and evaluation of an empirically derived self-rating instrument (HRS ‘Hypogonadism Related Symptom Scale’)
2009
While self-report screening instruments are highly sensitive to hypogonadism in the ageing male, they have lacked specificity as evidenced by low or absent correlations with testosterone. The purpose of this paper was to develop an economical and specific screening instrument for identifying hypogonadal ageing men. Based on a comprehensive study of physical, somatoform and affective complaints, sexual behaviour and function and hormonal parameters of 263 outpatients aged 40 years and above (M = 56.2; 40-84 years) recruited from six andrological outpatient departments in Germany, we identified those items correlating significantly with testosterone. By factor analyses, five factors were iden…
Oral lichenoid lesions associated with amalgam restorations : a prospective pilot study addressing the adult population of the Basque Country
2011
Oral lichenoid lesions (OLLs) are linked to a heterogeneous group of pathologies involving the oral mucosa that cannot be distinguished from the oral lichen planus excepting the fact that direct causal factors such as silver amalgam restorations (SARs) can be allocated to them. Purpose: To analyze the prevalence of mucosal lesions associated with SAR in a group of SAR carrying patients in the Basque Country. Study D esign: A clinical prospective study was carried out on 100 adult patients over 30 years of age at the UPV/ EHU Clinical Odontology Service whose rear teeth had at least one SAR. Patients were identified and mucosal lesions and amalgam restorations were characterized. Patch tests…
