Impact of exercise training and diet therapy on the physical fitness, quality of life, and immune response of people living with HIV/AIDS: a randomized controlled trial.

BACKGROUND: Exercise and dietary nutrition are considered crucial in human immunodeficiency virus (HIV)/ acquired immunodeficiency syndrome (AIDS) treatment protocols and people living with HIV/AIDS (PLWHA) rehabilitation care. However, there is no well-studied research evaluating the effects of combined interventions on the fitness and immune systems of PLWHA. Therefore, this study aimed to analyze the effects of exercise and dietary intervention on physical fitness, quality of life and immune response in PLWHA. METHODS: This was an experimental study, with a sample of 25 male PLWHA divided into two groups: the intervention group (IG: 12 participants) and the control group (CG: 13 participants). All participants have not had any exercise habits and nutritional supplements in the past six months. The participants in the IG completed 45 min of exercise (60-80% HRmax) 4 times per week for 4 weeks. The exercise was in the form of brisk walking or running. They were also given a nutritional dietary supplement 3 times a day for 4 weeks. The 13 individuals in the CG continued their normal daily life (physical activity and diet). The following parameters were evaluated before and after the intervention: body composition, physical fitness, immune response, quality of life (QoL), stress, dietary behavior, dietary habits, exercise motivation, and physical self-efficacy. RESULTS: The significant changes were observed in burnout of stress variables and physical efficiency index (PEI) of physical fitness in the IG (p =.023). Moreover, in the saliva samples, sal-T levels significantly increased only after the intervention in the IG (p =.012). Additionally, regarding the analysis of the interaction (group × time), there was a significant improvement in the reaction speed (p =.001) and grip strength (left: p =.002, right: p =.030) and a significant difference in physical satisfaction in QoL (p =.001), stress burnout (p =.043), self-confidence in physical efficacy (p =.045), external display (p =.008), and fulfillment (p =.047) in exercise motivation. Moreover, the significant effect of the intervention on emotional eating in dietary behavior was shown in the comparison of the IG before and after intervention (p =.001) and in the comparison of the IG group with the CG after the experiment (p =.013). However, there was no significant effect of time or interaction between the condition and time on body composition. CONCLUSIONS: In conclusion, exercise training and diet therapy caused changes in physical fitness and Sal-T levels, which had positive effects on the health promotion of PLWHA.

Effects of blood flow restriction training on bone metabolism: a systematic review and meta-analysis.

Introduction: The efficacy of low-intensity blood flow restriction (LI-BFR) training programs in bone metabolism remains unclear compared to low-intensity (LI) training and high-intensity (HI) training. The aim of this review was to quantitatively identify the effects of LI-BFR training on changes in bone formation markers (i.e., bone-specific alkaline phosphatase, BALP), bone resorption (i.e., C-terminal telopeptide of type I collagen, CTX) and bone mineral density (BMD) compared with conventional resistance training programmes. Additionally, the effectiveness of walking with and without BFR was assessed. Methods: PubMed, Scopus, SPORTDiscus, Web of Science and Google Scholar databases were searched for articles based on eligibility criteria. Review Manager Version 5.4 was used for Meta-analysis. Physiotherapy Evidence Database (PEDro) was applied to assess the methodological quality of studies. Results: 12 articles were included in the meta-analysis, with a total of 378 participants. Meta-results showed that compared with LI training, LI-BFR training induced greater increments in BALP (young adults: MD = 6.70, p < 0.001; old adults: MD = 3.94, p = 0.002), slight increments in BMD (young adults: MD = 0.05, p < 0.00001; old adults: MD = 0.01, p < 0.00001), and greater decrements in CTX (young adults: MD = -0.19, p = 0.15; old adults: MD = -0.07, p = 0.003). Compared with HI training, LI-BFR training produced smaller increments in BALP (young adults: MD = -6.87, p = 0.24; old adults: MD = -0.6, p = 0.58), similar increments in BMD (MD = -0.01, p = 0.76) and similar decrements in CTX (young adults: MD = 0, p = 0.96; old adults: MD = -0.08, p = 0.13). Although there were only two studies on walking training intervention, walking training with BFR had a better effect on bone metabolism than training without BFR. Discussion: In conclusion, LI-BFR training induces greater improvements in bone health than LI training, but is less effective than HI training. Therefore, LI-BFR training may be an effective and efficient way to improve bone health for untrained individuals, older adults, or those undergoing musculoskeletal rehabilitation.

The Effects of Exercise on Acute Immune Responses in Relative Leisure-Deprived People Living with HIV/AIDS: A Pilot Study.

Exercise training involving exercises of optimal intensity and duration improves psychological and medical variables in relative leisure-deprived people living with HIV/AIDS. This study aimed to analyze associated psychological variables and the effect of exercise intensity and duration on immune responses in relative leisure-deprived people infected with HIV. The participants completed different moderate-intensity exercises (30 min (60−80% HRmax) and 45 min (60−80% HRmax)) and high-intensity exercise for 10 min (>80% HRmax). Levels higher than "normal" were rated for relative leisure deprivation, indicating relative deprivation of leisure among participants. The overall level of quality of life was "normal", indicating that quality of life was not considered high. The stress level was psychologically considered low. Time had a significant effect on cortisol levels (p < 0.05). Compared to pre-exercise, cortisol level was significantly decreased immediately after moderate exercise for 45 min and 3 h post-exercise after high-intensity exercise for 10 min (p < 0.05). However, time and the interaction of condition and time had no significant effect on IL-6 and sIgA levels (p > 0.05). Despite the small sample size of this pilot study, the results demonstrate that moderate-intensity exercise can be recommended to improve the health and quality of life of people infected with HIV.

Molecular mechanisms underlying the participation of Ribonuclease T2 gene into self-incompatibility of Citrus grandis var. Shatianyu Hort.

The RIB (ribonuclease T2) of Citrus grandis var. Shatianyu Hort involved in self-incompatibility (SI) mechanism was identified by prokaryotic expression. RT-qPCR results showed that the expression level of RIB in self pollinated stigma is significantly higher than that in cross pollinated stigma. A vector for prokaryotic expression of RIB was constructed after codon-optimization, and the recombinant protein was induced and purified. In vitro pollen germination test indicated that the RIB protein markedly inhibited pollen germination and pollen tube growth. The result is helpful for better understanding of the molecular mechanism underlying the SI in C. grandis.

Complete mitochondrial genome of Shinisaurus crocodilurus (Squamata: Shinisaurus) and its genetic relationship with related species.

The 16,585 base pairs mitochondrial genome of Shinisaurus crocodilurus was determined by using PCR amplification and DNA sequencing. To determine the phylogenetic position of S. crocodilurus with related species within Squamata, the phylogenetic tree was reconstructed with the concatenated nucleotide sequences of the 12 heavy-strand-encoded protein genes. Phylogenetic analyses based on maximum parsimony and Bayesian inference methods consistently support that the S. crocodilurus was closely related to the Helodermatidae within a monophyletic Anguimorpha group. And the result here contradicted the monophyly of Varanoidea (Varanidae + Helodermatidae). In addition, the Gekkonidae was found to possess a basal phylogenetic position within squamata and the traditional hypothesis of monophyletic lineages of Iguania and Scleroglossa was not supported in this study.

Genetic variation and differentiation of Gekko gecko from different populations based on mitochondrial cytochrome b gene sequences and karyotypes.

Black-spotted and red-spotted tokay geckos are distributed in different regions and have significant differences in morphological appearance, but have been regarded as the same species, Gekko gecko, in taxonomy. To determine whether black-spotted and red-spotted tokay geckos are genetically differentiated, we sequenced the entire mitochondrial cytochrome b gene (1147 bp) from 110 individuals of Gekko gecko collected in 11 areas including Guangxi China, Yunnan China, Vietnam, and Laos. In addition, we performed karyotypic analyses of black-spotted tokay geckos from Guangxi China and red-spotted tokay geckos from Laos. These phylogenetic analyses showed that black-spotted and red-spotted tokay geckos are divided into two branches in molecular phylogenetic trees. The average genetic distances are as follows: 0.12-0.47% among six haplotypes in the black-spotted tokay gecko group, 0.12-1.66% among five haplotypes in the red-spotted tokay gecko group, and 8.76-9.18% between the black-spotted and red-spotted tokay geckos, respectively. The karyotypic analyses showed that the karyotype formula is 2n = 38 = 8m + 2sm + 2st + 26t in red-spotted tokay geckos from Laos compared with 2n = 38 = 8m + 2sm + 28t in black-spotted tokay geckos from Guangxi China. The differences in these two kinds of karyotypes were detected on the 15th chromosome. The clear differences in genetic levels between black-spotted and red-spotted tokay geckos suggest a significant level of genetic differentiation between the two.

It is listed as a vulnerable species by the International Union for Conservation of Nature and Natural Resources Red List and also an endangered species in China. The genome is 16,578 bp in size. Its gene arrangement pattern was identical with those of Manis tetradactyla. We compared the mitochondrial genome of M. pentadactyla with that of the M. tetradactyla. Nucleotide sequence similarity between the two whole mitochondrial genomes was 79.30%, and the relatively low similarity seems to indicate that the two species are distinctly separated on the species level. The information on the mitochondrial genome comparison of the two species was discussed in detail in this paper.

The complete mitochondrial genome of Chrysolophus pictus (Galliformes: Phasianidae) and a phylogenetic analysis with related species.

The 16,678 bp mitochondrial genome of the Chrysolophus pictus has been sequenced in this paper. To determine the phylogentic position of C. pictus with related species within Phasianidae, the phylogenetic tree was reconstructed with the concatenated nucleotide dataset of the 12 heavy-strand-encoded protein genes. The phylogenetic analysis was carried out using maximum parsimony (MP) and Bayesian inference (BI) methods. MP and BI phylogenetic trees here showed similar topology and consistently suggested that C. pictus shared a close relationship with Phasianus versicolor. The results also showed that the Meleagris gallopavo possessed a basal phylogenetic position within Phasianidae, which may imply that it should be classified into the Phasianidae.
