Short-term changes in median nerve neural tension after a suboccipital muscle inhibition technique in subjects with cervical whiplash: A randomised c…
2014
Abstract Objectives To assess the immediate effect of a suboccipital muscle inhibition (SMI) technique on: (a) neck pain, (b) elbow extension range of motion during the upper limb neurodynamic test of the median nerve (ULNT-1), and (c) grip strength in subjects with cervical whiplash; and determine the relationships between key variables. Design Randomised, single-blind, controlled clinical trial. Setting Faculty of Nursing, Physiotherapy and Podiatry, University of Seville, Spain. Participants Forty subjects {mean age 34 years [standard deviation (SD) 3.6]} with Grade I or II cervical whiplash and a positive response to the ULNT-1 were recruited and distributed into two study groups: inter…
Maternal and paternal occupational exposure to agricultural work and the risk of anencephaly.
2006
Aims: To evaluate the association between parental occupational exposure to agricultural work and the risk of anencephaly in three Mexican states. Methods: A paired case control study (1:1) was done based on records of the Epidemiological Surveillance System of Neural Tube Defects in Mexico; 151 cases of anencephaly of more than 20 weeks’ gestation were selected between March 2000 and February 2001. Controls were selected from the same maternity services as those of the cases and were born alive without congenital malformations. Information was obtained from both parents by means of a general questionnaire, a food frequency questionnaire, and a specific questionnaire on occupational exposur…
Age and Grip Strength Predict Hand Dexterity in Adults.
2015
In the scientific literature, there is much evidence of a relationship between age and dexterity,\ud where increased age is related to slower, less nimble and less smooth, less coordinated\ud and less controlled performances. While some suggest that the relationship is a direct consequence\ud of reduced muscle strength associated to increased age, there is a lack of research\ud that has systematically investigated the relationships between age, strength and\ud hand dexterity. Therefore, the aim of this study was to examine the associations between\ud age, grip strength and dexterity. 107 adults (range 18-93 years) completed a series of hand\ud dexterity tasks (i.e. steadiness, line tracking…
Lipid peroxidation and nitric oxide metabolites in sedentary subjects and sportsmen before and after a cardiopulmonary test.
2012
Our aim was to investigate the effects of an exercise test on some indices of oxidative status and endothelial function, in trained and untrained subjects. We examined lipid peroxidation, nitric oxide metabolites (NOx) and their ratio before and after a cardiopulmonary test, using a cycloergometer. We enrolled 60 male subjects who practiced sport unprofessionally, subdivided in two groups (A and B) according to the values of VO2max. Group A included sportsmen with poor or fair aerobic fitness (VO2max 39 ml/Kg/min). The control group included 19 male sedentary subjects. Lipid peroxidation was evaluated by detection of the thiobarbituric acid-reactive substances (TBARS); the NOx were evaluate…
Complex regional pain syndrome: evidence for warm and cold subtypes in a large prospective clinical sample.
2016
Limited research suggests that there may be Warm complex regional pain syndrome (CRPS) and Cold CRPS subtypes, with inflammatory mechanisms contributing most strongly to the former. This study for the first time used an unbiased statistical pattern recognition technique to evaluate whether distinct Warm vs Cold CRPS subtypes can be discerned in the clinical population. An international, multisite study was conducted using standardized procedures to evaluate signs and symptoms in 152 patients with clinical CRPS at baseline, with 3-month follow-up evaluations in 112 of these patients. Two-step cluster analysis using automated cluster selection identified a 2-cluster solution as optimal. Resul…

Polymorphisms in the N-methyl-D-aspartate receptor 1 and 2B subunits are associated with alcoholism-related traits.
2003
Abstract Background This study examined the hypothesis that allelic variants of the ionotropic glutamatergic N-methyl-D-aspartate receptor (NMDAR) are associated with vulnerability to alcoholism and some related traits. Methods We investigated the silent G2108A and C2664T polymorphisms of the NMDAR1 and the NMDAR2B genes, respectively. The case control study included 367 alcoholic and 335 control subjects of German origin. The family-based study comprised 81 Polish alcoholic patients and their parents using the transmission disequilibrium test. Results The genotype frequencies of the NMDAR1 polymorphism differed significantly between control and alcoholic subjects. This difference was also …
Polymorphonuclear integrins, membrane fluidity, and cytosolic Ca(2+) content after activation in essential hypertension.
2000
Abstract —The purpose of this research was to obtain further information about the role of polymorphonuclear leukocytes in essential hypertension. These cells could be involved in the pathogenesis of organ injury. Thirty subjects (14 men and 16 women) with essential hypertension were enrolled. In these subjects we determined, at baseline and after in vitro activation with 4-phorbol 12-myristate 13-acetate and N -formyl-methionyl-leucyl-phenylalanine, the polymorphonuclear leukocyte membrane fluidity, obtained by labeling the cells with 1-[4-(trimethylamino)phenyl]-6-phenyl-1,3,5-hexatriene, cytosolic Ca 2+ concentration, obtained by marking the cells with Fura 2-AM, and integrin pattern (C…
Paradoxical heat sensation in patients with multiple sclerosis
1996
Temperature thresholds were determined in 16 patients with probable or definite multiple sclerosis, in six patients with possible but unconfirmed multiple sclerosis and in 34 healthy subjects, using the method of limits and the thermal sensory limen (TSL) of the MarStock technique. A significant proportion of the patients had thresholds outside the 2.5 SD range for normal subjects, both for warmth detection threshold and TSL. In addition, 10 patients with probable or definite multiple sclerosis and one patient with possible multiple sclerosis reported a paradoxical heat sensation, i.e. a sensation of warmth elicited by a cold stimulus. This illusion was almost exclusively observed with the …
Occupation, education, and Parkinson's disease: A case-control study in an Italian population
1996
Current epidemiologic data on the association between occupational exposures and Parkinson's disease (PD) are inconsistent. In a case-control study, we investigated the associations between occupation and PD and between education and PD. The cases (n = 62) were those identified in a prevalence survey (door-to-door, two-phase) of three Sicilian municipalities, as a November 1, 1987. We then randomly selected from the general population two controls for each case, matched for age ( +/- year), sex, and municipality (n = 124). Information on current and past occupations and education for cases and controls was obtained during the survey. Subjects who worked for most of their lives as farmers we…
