Background Most studies on the association of maternal pregnancy weight with offspring weight trajectory have a short follow-up *** study aimed to explore the associations of maternal prepregnancy body mass index(BMI)and gestational weight gain(GWG)with childhood weight trajectories in a 7-year birth *** A total of 946 mother–child pairs(467 boys and 479 girls)from a longitudinal birth cohort in Tianjin City,China,were included in this study,ranging from pregnancy to offspring at 7 *** outcome variable was defined as overweight or not overweight in offspring at the last round.A group-based trajectory model was applied to identify childhood BMI trajectory *** Five discrete BMI trajectory groups were identified and characterized as constant underweight(25.2%),constant normal weight(42.8%),and high or increasing trajectory[at risk of overweight(16.9%),progressive overweight(11.0%)and progressive obesity(4.1%)].Maternal prepregnancy overweight was associated with 1.72(95%CI 1.14–2.60,P=0.01)to 4.02(95%CI 1.94–8.36,P<0.001)times the risk of all high or increasing trajectory groups,and excessive GWG was related to groups at risk of overweight[relative risk ratio(RRR)2.09,95%CI 1.27–3.46,P=0.004]and progressive obesity(RRR 3.33,95%CI 1.13–9.79,P=0.029).Children in all high or increasing trajectory groups were associated with greater overweight risk at the last round[risk ratios(RRs)ranged from 3.54(95%CI 2.53–4.95,P<0.001)to 6.18(95%CI 4.05–9.42,P<0.001)].Conclusion Maternal prepregnancy overweight and excessive gestational weight gain were associated with increasing or high-level childhood body mass index trajectories as well as a greater risk of overweight at 7 years.

Let a and b be positive integers such that a≤b and a≡b(mod 2).We say that G has all(a,b)-parity factors if G has an h-factor for every function h:V(G)→{a,a+2,…,b-2,b} with b|V(G)| even and h(v)≡b(mod 2) for all v∈V(G).In this paper,we prove that every graph G with n≥2(b+1)(a+b) vertices has all(a,b)-parity factors if δ(G)≥(b^(2)-b)/a,and for any two nonadjacent vertices u,v ∈V(G),max{d_(G)(u),d_(G)(v)}≥bn/a+***,we show that this result is best possible in some sense.

Fungal residues were more sensitive to nitrogen addition than bacterial residues in a meadow grassland soil

Fungi are more sensitive to long-term nitrogen addition than ***-term nitrogen addition significantly reduces fungal biomass, but promotes the accumulation of fungal residues in ***-term nitrogen addition has no significant impact on bacterial biomass and *** (N) addition can significantly affect the amount of soil carbon (C) pools through biological routes, and microbial residues are important components of soil carbon pools. However, it remains unclear how N addition affects the accumulation of soil microbial residues in meadow grasslands. This study analyzed the effects of N addition on microbial residues in a meadow grassland soil, and the key factors affecting the accumulation of microbial residues under N addition were analyzed in combination with soil physicochemical properties and microbial community structure. The results showed that N addition significantly changed the structure of the microbial communities and the accumulation of microbial residues, mainly manifested by a significant decrease in fungal biomass and the fungal/bacterial ratio (F/B), but had no significant effect on bacterial or total microbial biomass (PLFAs). N addition significantly increased the accumulation of fungal residues (7.45%), but had no significant effect on the accumulation of bacterial residues or total amino sugar (TAS). We found that fungal residues were more affected by soil environmental factors than bacterial residues. The results of the random forest analysis showed that bacterial biomass under N addition was the most important predictor of soil bacterial residues, whereas total N (TN), pH and F/B were the most important predictors of soil fungal residue. In summary, our results indicate that fungal communities and residues accumulation play important roles in regulating the response of grassland soil C to N addition, further enhancing our understanding of the mechanisms of soil carbon pool to N addition.
