We analyse the renormalization of the of two-nucleon interaction with multiple subtractions in peripheral waves considering two chiral forces at N3LO. Phase shifts at low energies are then computed ...with several subtraction points below \mu = 10 / fm. We show that for most peripheral waves the phase shifts have nearly no dependence on the renormalization scale. In two cases the phase shifts converge slowly as the renormalization scale approaches \mu = 1 / fm and in one case the phase shifts presented oscillations with respect to the subtraction point \mu.
Background: Obesity is characterized by excessive accumulation of adipose tissue and is associated with higher risk of metabolic diseases and other comorbidities. Efficacious strategies including a ...diet high in “functional foods” are promising. Plukenetia huayllabambana known as Sacha Inchi (SI), is a legume which seeds are rich in proteins, tocopherols, and fatty acids such as omega-3 (ω-3). The latter has emerged as a potential protective nutrient against the cardiometabolic risks associated with obesity. Omega-3 changes the membrane lipid profile of hepatic and adipose cells triggering the expression of antioxidant and anti-inflammatory genes. However, there are few reports in relation to the effect of these oils in inflammatory and stress response related to obesity. In this sense, the present study evaluated the effect of SI oil emulsion on nitric oxide and leptin levels in the liver and some markers of oxidative stress and inflammation in adipose tissue from the rodent obesity model.Methods: Six groups were formed: Not obese control group (Noc), obese control (Oc), two groups treated with the emulsion of SI oil (Os1:0.25g ω-3/day; Os2:0.5g ω-3/day), one obese group treated with atorvastatin (Oa) and one group treated with atorvastatin plus the emulsion of SI oil (Oas2).Results: Os1 and Os2 lowered nitric oxide and increased liver leptin levels. In the adipose tissue, the superoxide dismutase and reducing antioxidant power increased significantly in Os1 and Os2 groups. The anti-inflammatory marker IL-4 wasalso increased in Os2, Oa and Oas2 compared to the Oc and IL-10 increased in Oas2 group.Conclusion: Our study suggests that the emulsion of SI oil can modify the inflammatory and stress responses associated with obesity and it can be incorporated as a promising functional food.Keywords: Inflammation, leptin, obesity, nitric oxide, oxidative stress, SI oil emulsion.
Reactive oxygen species, as singlet oxygen (1O2) and hydrogen peroxide, are continuously generated by aerobic organisms, and react actively with biomolecules. At excessive amounts, 1O2 induces ...oxidative stress and shows carcinogenic and toxic effects due to oxidation of lipids, proteins and nucleic acids. Singlet oxygen is able to react with DNA molecule and may induce G to T transversions due to 8-oxodG generation. The nucleotide excision repair, base excision repair and mismatch repair have been implicated in the correction of DNA lesions induced by 1O2 both in prokaryotic and in eukaryotic cells. 1O2 is also able to induce the expression of genes involved with the cellular responses to oxidative stress, such as NF-κB, c-fos and c-jun, and genes involved with tissue damage and inflammation, as ICAM-1, interleukins 1 and 6. The studies outlined in this review reinforce the idea that 1O2 is one of the more dangerous reactive oxygen species to the cells, and deserves our attention.

A renormalization scheme for the nucleon-nucleon (NN) interaction based on a subtracted
T-matrix equation is proposed and applied to the one-pion-exchange potential supplemented by contact ...interactions. The singlet and triplet scattering lengths are given to fix the renormalized strengths of the contact interactions. With only one scaling parameter (μ), the results show an overall very good agreement with neutron-proton data, particularly for the observables related to the triplet channel. The agreement is qualitative in the

•The phenotypic plasticity of sugarcane cultivars was evaluated under contrasting soil water conditions.•Partitioning of photoassimilates in sugarcane is not influenced by moderate levels water ...stress.•Sugarcane varieties can save up to 25% of the applied water under moderate deficit irrigation.•Higher water use efficiency under limit water conditions was found for specific sugarcane varities.•Under deficit irrigation, biomass yield should be prioritized to the detriment of sucrose concentration in stalks.
Studies of sugarcane varieties grown under water-restrictive conditions are necessary because climate changes may result in insufficient rain for agriculture and selecting or breeding drought-tolerant cultivars will become more and more important. This study aimed to quantify the accumulation and partitioning of biomass, as well as water use efficiency of commercial sugarcane varieties under different soil water availability conditions throughout the growing season. The study was conducted during two cropping cycles in Southeast Brazil (22.7 °S, 47.6 °W). Four soil moisture availability regimens were set up to provide 100, 75, 75* and 50% of the water demand of eight commercial varieties of sugarcane (CTC15, CTC17, RB867515, RB92579, RB931011, RB966928, IAC5000, and NCo376). The total aboveground biomass was measured in both crop cycles. Our results indicate that two Brazilian varieties (CTC15 and CTC17) and one South African variety (NCo376 - Canegrow DSSAT reference), increased their water use efficiency when grown under an irrigation deficit of 75% of normal, without yielding less biomass. We did not observe any change in sucrose content under controlled water deficits; however, the studied varieties showed different biomass partitioning: RB966928 had the largest biomass fraction allocated in the stalks (0.59), while IAC5000 showed the lowest fraction (0.51). We verified that the harvest index for sucrose was not altered by reduced irrigation, but that its variability was attributed to the genotype inherited from traditional breeding programs. Thus, we conclude from these results that increased sugar yield per unit area is only possible nowadays by increasing sugarcane biomass productivity under highly efficient irrigation conditions to minimize the loss of yield from water stress.
