Depression is more prevalent in obese individuals and those with diabetes, compared to the general population. This study examined the effect of resistance training on depressed mood in individuals with high (HiMF, n ≥ 2) and low (LoMF, n ≤ 1) numbers of risk factors for metabolic syndrome and type 2 diabetes. The primary hypothesis was that resistance training would significantly reduce depressed mood, as measured by the Cardiac Depression Scale (CDS), in individuals with HiMF. Fifty-five middle-aged volunteers (50.8 ± 0.9 years, mean ± SEM) from the general community participated in the study. After initial allocation to HiMF or LoMF, participants were randomly allocated to 4 groups, HiMF training (HiMFT), HiMF control (HiMFC), LoMF training (LoMFT), and LoMF control (LoMFC). Participants underwent resistance training involving major muscle groups on 3 d·wk(-1) for 10 weeks. Before and after interventions (training or control), participants completed the CDS to assess change in the level of depressed mood. Following resistance training, the CDS score of the HiMFT group was reduced by -14.8 ± 4.9 points on the CDS, a significant improvement in comparison to both baseline (p = 0.01) and HiMFC (p = 0.049) values. No significant change was observed for LoMFT. In the HiMF group only, the percent change in relative muscle strength was correlated with the Δ change in CDS; r = -0.46, p = 0.008. Resistance exercise training programs that consist 7 exercises for the major muscle groups at both low-moderate and moderate-high intensities appear to alleviate depressed mood in individuals with clusters of metabolic risk factors. 相似文献

Ecological and historical factors of the Balearic archipelago (Western Mediterranean Sea) result is some peculiarities to its rotifer fauna. A group of warm-stenothermous species are frequent seasonally in the islands. Among them the occurrence of Keratella procurva (Thorpe, 1912), a pantropical species, is remarkable, and this is found more or less abundantly on each island. We briefly describe the different habitat categories of the archipelago. Clustering the collected species we relate each community type to its habitat; in this sense we distinguish 4 community type in the islands corresponding to different environments. This work also summarizes all the obtainable data on the rotifer fauna of the Balearic archipelago, adding the results of the investigations done in the last survey (spring, 1989); a checklist, including 100 species from the archipelago, is shown (69 Majorca, 72 Minorca, 24 Ibiza, 25 Formentera). Some examples of pantropical distribution are given, and the biotic and abiotic factors which determine the colonization of the islands by these species are discussed. 相似文献

Nucleosomes have been fractionated on nondenaturing polyacrylamide gels, and nucleosome subtypes containing the Drosophila melanogaster specific protein D1 and ubiquitinated core histone H2A were identified by solubility in 0.1 M NaCl before nucleoprotein gel electrophoresis. Nucleosomes which contain DNA complementary to the 1.672 density simple satellite (sequence-AATAT-) bind protein D1, as demonstrated by two-dimensional hybridization mapping. This hybridization pattern allows the identification of D1 dinucleosomes, which, like D1 mononucleosomes, are reduced in mobility on the first dimension (nucleoprotein) gel by the addition of D1, an AT sequence-specific DNA-binding protein. The 1.705 density simple satellite (sequence-AAGAG-) is also found in nucleosomes, in a radically different subset from those of the -AATAT- DNA sequence. -AAGAG- nucleosomes do not contain D1 protein, but appear to be enriched in ubiquitinated core histone H2A. One-dimensional hybridization patterns suggest that -AAGAG- nucleosomal DNA is rapidly trimmed to a shorter DNA length than either bulk or -AATAT- nucleosomes. 相似文献

Cactus stems, the cladodes of Opuntia spp. cacti, are consumed in Mexico and other countries due to their fresh and herbaceous flavor, and because of their widely known nutraceutical benefits. In order to extend the postharvest life of this vegetable, the effect of a modified atmosphere packaging (MAP) was studied in cactus stems of the cultivar Atlixco stored at 4 ± 1 °C for 20 days under three types of atmospheres: (1) air (passive atmosphere), (2) 5 kPa O2 + 4 kPa CO2, and (3) N2. During storage, the titratable acidity decreased and the color of cladodes became darker and less green; however, the 5 kPa O2 + 4 kPa CO2 atmosphere was able to preserve both quality characteristics. All modified atmospheres reduced weight loss (from 8 to <2%) and the symptoms of chilling injury, and this physiological disorder appeared earlier in controls than in MAP-stored cladodes. The levels of fermentation metabolites were low in all three evaluated atmospheres. Because of this, only cladodes stored under the N2 atmosphere were selected for furthersensory analysis of the MAP effect on odor perception as evaluated by a trained panel. Results indicated that there was no detrimental effect (atypical odors) of MAP on this sensory characteristic. We conclude that cultivar Atlixco is suitable for preservation using MAP technology. 相似文献

We developed 22 new microsatellite loci for the fisher (Martes pennanti), a North American mesocarnivore. The loci were developed with samples from the southern Sierra Nevada Mountains in California, and were screened with samples from this population and four other populations. We observed a range of six to 21 polymorphic loci per population, with the Sierra Nevada population exhibiting markedly lower levels of variation compared to the other four. 相似文献
