To evaluate cell-free DNA (cfDNA) redraws and pregnancy outcomes following low fetal fraction (FF) cfDNA failures, as it has been suggested that a failed cfDNA screen due to insufficient FF carries increased risk for fetal aneuploidy.

Here >200,000 consecutive samples were reviewed and >1,100 patients were identified with a failed cfDNA due to low FF using genome-wide massively parallel sequencing. Redraw results following the initial low FF failure were analyzed, as well as pregnancy outcomes for patients with repeated low FF failure on redraw.

Upon redraw 84.2% of samples yielded a reportable result with no enrichment of aneuploidy observed (p=0.332). Higher maternal weights and multifetal pregnancy rates were observed in samples with insufficient FF. In patients with repeated low FF failure on redraw, almost all pregnancies resulted in apparently healthy liveborns.

Insufficient FF was not an indicator of aneuploidy risk or adverse pregnancy outcomes in this study. Caution should be taken in generalizing aneuploidy risk to all low FF cfDNA failures. Redrawing may be an appropriate next step, as proceeding directly with diagnostic testing for aneuploidy may be unwarranted for most patients.

Excessive occlusal forces and occlusal trauma have been implicated as co-destructive factors for periodontitis in animal models. The objective of this study was to assess the association between occlusal trauma and periodontitis.

A total of 167 cases and 205 controls were included for analysis. Occlusal trauma was the exposures of interest and was registered for cases and controls. Additional clinical co-variables were registered as well for further analysis. The association of the exposure and periodontitis was determined by the odds ratio and logistic regression analysis adjusted for confounders.

Amalgam restorations, pathogenic occlusion and occlusal trauma were more frequent in cases as compared to controls (P ≤0.05). The distribution of pathogenic occlusion and occlusal trauma was similar according to the stage and class of periodontitis. Logistic regression analysis showed a significant association for cigarette smoking, systemic conditions, amalgam restorations, pathogenic occlusion, and occlusal trauma with periodontitis (P ≤0.05). L-Ascorbic acid 2-phosphate sesquimagnesium After adjusting for confounding variables in the model, amalgam restorations and occlusal trauma remained strongly associated with periodontitis (P ≤0.05).

Occlusal trauma is strongly associated with periodontitis. Additional long-term prospective studies are necessary to further understand the impact of the occlusal condition and periodontitis.

Rice bran oil is unique among edible oils owing to its rich source of commercially and nutritionally important phytochemicals, such as oryzanol. γ-Oryzanol performs an important role in the stability of rice bran oil. The crude rice bran oil obtained by solvent extraction is subjected to either chemical or physical refining to meet the specifications of edible-grade vegetable oil. These refining processes can cause the compounds present in rice bran oil to degrade. The aim of this study was to evaluate the stability of γ-oryzanol present in chemically and physically refined rice bran oils, when submitted to temperatures of 100, 140, and 180 °C for a period of 1368 h.

The chemically refined rice bran oil presented a lower γ-oryzanol content than the physically refined rice bran oil at all heating temperatures. The losses of γ-oryzanol at 100 °C, 140 °C, and 180 °C at the end of the heating periods for the chemically refined oil were 53.47%, 58.48%, and 97.05% respectively, and for the physically refined oirefined oil is better for maintaining a higher concentration of γ-oryzanol. © 2021 Society of Chemical Industry.The RAG1 and RAG2 proteins initiate the process of V(D)J recombination and therefore play an essential role in adaptive immunity. While null mutations in the RAG genes cause severe combined immune deficiency with lack of T and B cells (T- B- SCID) and susceptibility to life-threatening, early-onset infections, studies in humans and mice have demonstrated that hypomorphic RAG mutations are associated with defects of central and peripheral tolerance resulting in immune dysregulation. In this review, we provide an overview of the extended spectrum of RAG deficiencies and their associated clinical and immunological phenotypes in humans. We discuss recent advances in the mechanisms that control RAG expression and function, the effects of perturbed RAG activity on lymphoid development and immune homeostasis, and propose novel approaches to correct this group of disorders.

In this study, the alternative method of ohmic heating (OH) was applied to investigate its potential usage in the cooking process for pasta and its comparison with the conventional method. For this purpose, OH was operated at four different voltage gradients (10, 20, 30, 40 V cm

). The electrical conductivity of pasta σ (S m

) was calculated for the temperature range 22-95 °C and a three-phase linear relation between σ and temperature was determined.

According to the results, the energy consumption of the OH system and cooking time were lower than the conventional method. Energy conservation was about 73.7% at 40 V cm

and increased up to 90.4% (at 10 V cm

) with lower voltage gradients. Total cooking time, cooking loss, water absorption, degree of gelatinization, volume uptake, energy consumption and sensorial properties were investigated. No significant differences between the results of samples cooked with the conventional method and OH at 30-40 V cm

were found in terms of starch gelatinization degree, volume change, water absorption, and sensorial analysis (P > 0.
