Species turnover of abundant and rare taxa of total and active microbes, rather than species richness, explained the highest percentage of community variation. Rare taxa exhibited the most marked temporal turnover during three wetting-drying cycles. Members of Rhodospirillaceae were the major contributor to the resilience of abundant taxa of active microbes during the first wetting-drying cycle. Overall, these findings expand our current understanding of underlying assembly mechanisms of soil microbial communities responding to wetting-drying cycles.

The prospective relation of dietary vitamin A intake with hypertension remains uncertain. We aimed to investigate the relationship of dietary vitamin A intake with new-onset hypertension and examine possible effect modifiers in general population.

This prospective cohort study included 12,245 participants who were free of hypertension at baseline from China Health and Nutrition Survey (CHNS). Dietary intake was measured by 3 consecutive 24-h dietary recalls combined with a household food inventory. The study outcome was new-onset hypertension, defined as systolic blood pressure ≥140mmHg and/or diastolic blood pressure ≥90mmHg or diagnosed by physician or under antihypertensive treatment during the follow-up.

During a median follow-up duration of 6.1 years, a total of 4,304 (35.1%) participants developed new-onset hypertension. Overall, there was an L-shaped relation of total dietary vitamin A intake with new-onset hypertension (P for nonlinearity <0.001). Accordingly, compared with participants with lower vitamin A intake (quartile 1, <227.3μg RE/day), those with higher vitamin A intake (quartile 2-4, ≥227.3μg RE/day) had a significantly lower risk of new-onset hypertension (adjusted HR, 0.73; 95%CI 0.63, 0.78). Similar results were found for plant-derived vitamin A intake (adjusted HR, 0.65; 95% CI, 0.61, 0.70) or animal-derived vitamin A intake (adjusted HR, 0.76; 95% CI, 0.70, 0.82).

There was a L-shaped relation of dietary vitamin A intake with new-onset hypertension in general Chinese adults. Our results emphasized the importance of maintaining relatively higher vitamin A intake levels for the prevention of hypertension.

Poor nutritional habits are linked to higher perceived stress, but the relationship between fruit and vegetable (FV) intake and stress is uncertain. The primary aim of this cross-sectional study was to explore the relationship between FV intake and perceived stress in a population-based cohort of men and women aged ≥25 years from the Australian Diabetes, Obesity and Lifestyle (AusDiab) Study. A secondary aim was to investigate the relationship between serum carotenoids, biomarkers of FV intake, and perceived stress.

In Australian men and women, dietary intake was assessed using a Food Frequency Questionnaire in 1999-2000 (n=8689). CDK inhibition Perceived stress was assessed using a validated Perceived Stress Questionnaire [PSQ index values ranging from 0 (lowest) to 1 (highest)]. Serum carotenoids were measured in a subset of participants (n=1187) using high-performance liquid chromatography. Multivariable-adjusted linear and logistic regression were performed to investigate the associations between FV intake and percehealth and well-being.

In Australian adults, higher FV intake was associated with lower perceived stress, particularly in the middle-aged adults. These findings support current recommendations that fruit and vegetables are essential for health and well-being.

There have been several attempts to come up with a global operational definition of sarcopenia (S), and consequently, a definition of S has been established, to some extent. That said, the definition of sarcopenic obesity (SO), which is defined as the presence of obesity+sarcopenia, remains obscure, hindering evaluations of the prevalence and relevance of SO. It has yet to be elucidated whether SO is associated with worse functionality when compared to S alone (S without obesity). In the present study, we compare SO and S alone in terms of their associations with functional measures through the application of alternative definitions of SO. As a secondary output, we document the prevalence of SO based on alternative definitions.

This retrospective cross-sectional study included community-dwelling adults over 60 years of age who presented as outpatients to a university hospital between 2012 and 2020. All were evaluated for body composition (bioimpedance analysis), handgrip strength (Jamar hand dynamometer) sity may have a protective effect against the limitations of some functional measures, providing evidence of the possible protective effect of obesity in sarcopenic individuals.

Our results suggest that the SO definition confirmed, LMM adjusted by height2 has an ignorable prevalence in populations in which underweight or malnutrition is uncommon. Among sarcopenic older individuals, obesity may have a protective effect against the limitations of some functional measures, providing evidence of the possible protective effect of obesity in sarcopenic individuals.The scattered acoustic pressure and scattered cross section of bubbles is studied using the scattered theory of bubbles. The nonlinear oscillations of bubbles and the scattering acoustic fields of a spherical bubble cluster are numerically simulated based on the bubble dynamic and fluid dynamic. The influences of the interaction between bubbles on scattering acoustic field of bubbles are researched. The results of numerical simulation show that the oscillation phases of bubbles are delayed to a certain extent at different positions in the bubble cluster, but the radii of bubbles during oscillation do not differ too much at different positions. Furthermore, directivity of the acoustic scattering of bubbles is obvious. The scattered acoustic pressures of bubbles are different at the different positions inside and outside of the bubble cluster. The scattering acoustic fields of a spherical bubble cluster depend on the driving pressure amplitude, driving frequency, the equilibrium radii of bubbles, bubble number and the radius of the spherical bubble cluster.
