A Possible Role of Elevated Breast Milk Lactoferrin and the Cytokine IL-17 Levels in Predicting Early Allergy in Infants: A Pilot Study
In this study, we examined the relationship between levels of lactoferrin (LF) and IL-17 in human serum and breast milk and the development of allergy in children. LF and IL-17 levels were determined by ELISA in healthy (n=19) and allergic mothers (n=21) on the 5th day after delivery. Two years later, information on breastfeeding and allergic outcomes was collected by questionnaires from parents of both groups and district child care nurses. Significantly higher concentrations of LF were found in the breast milk of allergic mothers compared to the healthy controls. At 2 years of age, only those three infants became allergic from the atopic group in whose starting breast milk samples a very high LF level (306 μg mg–1 protein) or simultaneously elevated concentrations of LF and IL-17 were measured. These findings indicate that the very early measurement of LF and IL-17 levels in the breast milk of allergic mothers may help to predict the allergy development in their infants
Friedel-Type Oscillations in the Problem of Skin Effect in Degenerate Collisionless Plasma
It is shown that a Friedel type oscillations accompany skin effect in
degenerate plasma of a metal. It was learnt earlier that Friedel oscillations
take place under charge screening in quantum plasma. However the nature of
Friedel oscillations is not in the quantum character of the plasma, but in the
features of degenerate Fermi distribution, namely, in its sharp transformation
into zero directly just the other side of the Fermi surface. This circumstance
leads to the Frieldel-type oscillations under anomalous skin effect.Comment: 11 pages, 6 figure

Milk and dairy products: good or bad for human health? An assessment of the totality of scientific evidence
Background: There is scepticism about health effects of dairy products in the public, which is reflected in an increasing intake of plant-based drinks, for example, from soy, rice, almond, or oat.
Objective: This review aimed to assess the scientific evidence mainly from meta-analyses of observational studies and randomised controlled trials, on dairy intake and risk of obesity, type 2 diabetes, cardiovascular disease, osteoporosis, cancer, and all-cause mortality.
Results: The most recent evidence suggested that intake of milk and dairy products was associated with reduced risk of childhood obesity. In adults, intake of dairy products was shown to improve body composition and facilitate weight loss during energy restriction. In addition, intake of milk and dairy products was associated with a neutral or reduced risk of type 2 diabetes and a reduced risk of cardiovascular disease, particularly stroke. Furthermore, the evidence suggested a beneficial effect of milk and dairy intake on bone mineral density but no association with risk of bone fracture. Among cancers, milk and dairy intake was inversely associated with colorectal cancer, bladder cancer, gastric cancer, and breast cancer, and not associated with risk of pancreatic cancer, ovarian cancer, or lung cancer,while the evidence for prostate cancer risk was inconsistent.Finally,consumption of milk and dairy products was not associated with all-cause mortality. Calcium-fortified plant-based drinks have been included as an alternative to dairy products in the nutrition recommendations in several countries. However, nutritionally, cow’s milk and plant-based drinks are completely different foods,and an evidence-based conclusion on the health value of the plant-based drinks requires more studies in humans.
Conclusion: The totality of available scientific evidence supports that intake of milk and dairy products contribute to meet nutrient recommendations, and may protect against the most prevalent chronic diseases, whereas very few adverse effects have been reported
DeepTelos and DMLA – A Contribution to the MULTI 2022 Collaborative Comparison Challenge
The MULTI 2022 Collaborative Comparison Challenge was created to promote in-depth discussion between multi-level modeling approaches. This paper presents a comparison of DeepTelos- and DMLA-based solutions in response to the challenge. We first present each approach and solution separately, and then list the similarities and differences between the two solutions, discussing their relativestrengths and weaknesses. CC BY 4.0 [accepted version]</p
Effects of the stimuli-dependent enrichment of 8-oxoguanine DNA glycosylase1 on chromatinized DNA
8-Oxoguanine DNA glycosylase 1 (OGG1) initiates the base excision repair pathway by removing one of the most abundant DNA lesions, 8-oxo-7,8-dihydroguanine (8-oxoG). Recent data showed that 8-oxoG not only is a pro-mutagenic genomic base lesion, but also functions as an epigenetic mark and that consequently OGG1 acquire distinct roles in modulation of gene expression. In support, lack of functional OGG1 in Ogg1-/- mice led to an altered expression of genes including those responsible for the aberrant innate and adaptive immune responses and susceptibility to metabolic disorders. Therefore, the present study examined stimulus-driven OGG1-DNA interactions at whole genome level using chromatin immunoprecipitation (ChIP)-coupled sequencing, and the roles of OGG1 enriched on the genome were validated by molecular and system-level approaches. Results showed that signaling levels of cellular ROS generated by TNFα, induced enrichment of OGG1 at specific sites of chromatinized DNA, primarily in the regulatory regions of genes. OGG1-ChIP-ed genes are associated with important cellular and biological processes and OGG1 enrichment was limited to a time scale required for immediate cellular responses. Prevention of OGG1-DNA interactions by siRNA depletion led to modulation of NF-κB's DNA occupancy and differential expression of genes. Taken together these data show TNFα-ROS-driven enrichment of OGG1 at gene regulatory regions in the chromatinized DNA, which is a prerequisite to modulation of gene expression for prompt cellular responses to oxidant stress.
