A tailored telephone and email based exercise intervention induced reductions in various measures of body composition in physically inactive adults: …

2018

Obesity prevalence has increased the past decades and has become a serious public health problem. The aim of this six-month assessor-blinded, parallel-group randomized controlled trial was to assess the effect of a tailored telephone and email-based exercise intervention on various measures of body composition in a sample of apparently healthy and physically inactive adults. A total of 111 volunteering adults (40–55 yr) in Southern Norway were randomly assigned to an intervention group (IG; n = 39) or a no-information control group (CG; n = 50), by random allocation numbering. The IG received feedback on their health-related physical fitness, information on guidelines and recommendations fo…

Chemosensory signalling pathways involved in sensing of amino acids by the ghrelin cell

2015

AbstractTaste receptors on enteroendocrine cells sense nutrients and transmit signals that control gut hormone release. This study aimed to investigate the amino acid (AA) sensing mechanisms of the ghrelin cell in a gastric ghrelinoma cell line, tissue segments and mice. Peptone and specific classes of amino acids stimulate ghrelin secretion in the ghrelinoma cell line. Sensing of L-Phe occurs via the CaSR, monosodium glutamate via the TAS1R1-TAS1R3 while L-Ala and peptone act via 2 different amino acid taste receptors: CaSR & TAS1R1-TAS1R3 and CaSR & GPRC6A, respectively. The stimulatory effect of peptone on ghrelin release was mimicked ex vivo in gastric but not in jejunal tissue …

Auditory cortical and hippocampal local-field potentials to frequency deviant tones in urethane-anesthetized rats: An unexpected role of the sound fr…

2015

Abstract The human brain can automatically detect auditory changes, as indexed by the mismatch negativity of event-related potentials. The mechanisms that underlie this response are poorly understood. We recorded primary auditory cortical and hippocampal (dentate gyrus, CA1) local-field potentials to serial tones in urethane-anesthetized rats. In an oddball condition, a rare (deviant) tone ( p  = 0.11) randomly replaced a repeated (standard) tone. The deviant tone was either lower (2200, 2700, 3200, 3700 Hz) or higher (4300, 4800, 5300, 5800 Hz) in frequency than the standard tone (4000 Hz). In an equiprobability control condition, all nine tones were presented at random ( p  = 0.11). Diffe…

Somatotypes and handgrip strength analysis of elite Serbian sambo athletes

2021

The aim of this study was to establish whether there are differences between weight categories in different anthropometric measurements and handgrip strength between elite Serbian male and female sambo athletes divided into weight categories. A total of 70 elite Serbian sambo athletes participated in the study, who were participants of the World Cadet Sambo Championship held in Novi Sad. Athletes are classified into categories according to gender and official weight categories. Using anthropometry, we calculated somatotypes and hand-grip strength. For statistical analysis, we used a one-way analysis of variance and Tukey’s post hoc tests to compare group differences by weight categories. So…

Aspects of disordered eating continuum in elite high-intensity sports

2010

Dieting is an important risk factor for disordered eating and eating disorders. Disordered eating occurs on a continuum from dieting and restrictive eating, abnormal eating behavior, and finally clinical eating disorders. The prevalence of eating disorders is increased in elite athletes and for this group the cause of starting to diet is related to (a) perception of the paradigm of appearance in the specific sport, (b) perceived performance improvements, and (c) sociocultural pressures for thinness or an "ideal" body. Athletes most at risk for disordered eating are those involved in sports emphasizing a thin body size/shape, a high power-to-weight ratio, and/or sports utilizing weight categ…

Lipid Activates mTORC1 and mTORC2 in the Absorption of Dietary Triglycerides

2018

Mechanistic target of rapamycin (mTOR) senses amino acids; however, its role in lipid metabolism is less established. Organismal lipid requirements are largely met through dietary intake. How nutrient sensing mechanisms in gut interface with dietary fat remains unclear. Here we reveal fundamental and cooperative roles for mTOR complexes 1 and 2 (mTORC1/2) in absorption of dietary triglycerides. Dietary lipid activates mTORC1/2 signaling in gut. Hyperactivating mTORC1 by deleting Tsc1 is sufficient to promote triglyceride absorption and metabolic disease in high fat-fed mice. Conversely, blocking mTORC1/2 by deleting Raptor or Rictor each decreases triglyceride absorption. Loss of Raptor seq…

Hautknoten und Ulzera der Extremitäten bei einem Patienten mit rheumatoider Arthritis

2002

CASE HISTORY: While being treated with corticosteroids and methotrexate for rheumatoid arthritis, a 63-year-old man developed livid nodules on his lower arms, hands and feet, as well as fever, necrotizing skin ulcers and rupture of a finger extensor tendon. INVESTIGATIONS: No vasculitis was found in a biopsy of one of the nodules on the lower arm. Fast growing mycobacteria, classified as M. marinum by PCR, were cultured from wound swabs. TREATMENT AND COURSE: The lesions healed on administration of ciprofloxacin, ethambutol and clarithromycin as well as local treatment. CONCLUSION: Cutaneous lesions of an atypical mycobacterial infection are often misdiagnosed. This is especially so in immu…

Therapeutic laser guidelines: On the effects of laser radiation on human skin-fibroblast metabolism in culture

1989

A promising field of laser utilization is the modification of cell behaviour. Acting on cell biological functions it might be possible to use them to improve medical therapies. This possibility suggests investigation of dosimetry guidelines employing different wavelenghts, power and exposure durations for future potential use of lasers in medicine.
