ot pretreated with FO. In addition, confirming these assumptions, the decreased 5-HT levels in the hippocampus from induced-T1DM rats were increased after treatment with FLX (highest dose) or IMI (both doses), being this increase more pronounced in animal pretreated with FO. Intriguingly, in these animals pretreated with FO, the ineffective dose of FLX in association with FO was able to increase the levels of 5-HT. The decreased hippocampal levels of noradrenaline were increased only after IMI treatment, not being influenced by FO pretreatment. In conclusion, ours results pointed out that the choice of the DHA/EPA ratio may be an important factor to be considered for the FO antidepressant-like effectper se,but the FO treatment in this composition associated with the antidepressant drugs - especially that ones that increase preferentially the availability of 5-HT -, may represent a better alternative of treatment to individuals with T1DM-associated depression.Fascinating immunologic mechanisms that are crucial for pregnancy can, however, lead to the development of different skin conditions, of which atopic dermatitis (AD) is the most frequent one. AD in pregnancy may occur de novo or as a recurrence or exacerbation of known chronic AD. The changes in hormone levels that occur during pregnancy influence the cytokine balance and can lead to manifestation of eczematous lesions, currently classified as atopic eruption of pregnancy. The diagnosis of atopic eruption of pregnancy may be challenging, especially in patients who developed this skin disease de novo during gestation. The treatment is another challenge, because it needs to be safe for both the mother and especially the unborn child. Emollients make up the basis of the therapy. Topical corticosteroids and calcineurin inhibitors are also safe treatment options, and ultraviolet therapy can be added, if required. Use of cyclosporin A is possible for systemic therapy during pregnancy, whereas safety data on new drugs such as biologics approved for AD are limited to small case series. This review is aimed at summarizing available data on the mechanisms that lead to AD during gestation, differential diagnostic evaluations, and treatment options.

This study aimed to investigate the associations of domain-specific physical activity (PA) with the prevalence of depressive symptoms.

We analyzed data from 11,679 (5,056 men and 6,623 women) participants aged ³19 years in the Korea National Health and Nutrition Examination Survey (2016 and 2018 waves). Depressive symptoms were measured using the Korean version of the Patient Health Questionnaire-9 (PHQ-9), with a cut-off score for depression of 11. The participants were first categorized by sex, and then by their PA level in different PA domains into three different groups. We examined the correlations between domain-specific PA and depressive symptoms using logistic regression analysis after controlling for confounders.

Total amount of PA was not associated with depressive symptoms. However, in both sexes, those high in leisure and transport PA had lower levels of depressive symptoms compared with those with no leisure and transport PA (p for trend <0.001). After adjusting for covariates, those high in work PA showed a significantly higherlikelihood of having depressive symptoms both in male (OR= 2.74, 95% CI 1.56-4.82) and female participants (OR= 2.84, 95% CI 1.70-4.49), compared to those with no work PA.

Cross-sectional nature of the data prevents causal associations.

Although the total amount of PA participation was not associated with depressive symptoms, domain-specific PAs were differently associated with depressive symptoms. Specifically, higher amount of work PA was significantly associated with higher prevalence of depressive symptoms; this topic deserves further attention and future investigation.

Little is known about the association between perceived social support (PSS) and suicidal ideation in Chinese adolescents. This study was to examine the association of perceived social support and suicidal ideation (SI) and the mediating role of depressive symptoms in a large sample of adolescents in China.

A total of 11,831 adolescents who participated in the baseline Shandong Adolescent Behavior & Health Cohort were included for analysis. Perceived social support, depressive symptoms, and other variables were assessed by a self-administrated questionnaire. Path analysis was used to estimate the association between PSS, depressive symptoms, and suicidal ideation.

The prevalence rate of SI in the past year was 12.5%. Suicidal ideation and depressive symptoms were significantly associated with low PSS from family, friends, and significant others. Path analysis revealed that depressive symptoms partially mediated the relationship between PSS from family, friends, and significant others and suicidal ideation. After controlling for covariates, the mediation effect proportion of depressive symptoms on the associations between perceived social support from family, friends, and significant others and SI ranged from 19.20% to 62.12%.

As this is a cross-sectional study, no causal relationship could be made.

Depressive symptoms partially mediated the association between perceived social support and suicidal ideation. Longitudinal research is needed to better understand the association between social support and suicidal ideation in adolescents.

In this work, PHB polymer has been tested in an animal model for colorectal cancer. In the animal model, PHB has been able to reduce the number of polyps by 48,1%, and the tumoral extension area by 58,1%. Also, PHB induces a selective increase in beneficial gut bacterial taxons in this animal model, and a selective reduction in pro-inflammatory taxons, demonstrating its value as a nutraceutical compound. This antitumor effect is caused by gut production of 3-hydroxybutyrate and butyrate. In this animal model, 3-hydroxybutyrate is also observed in plasma and in brain tissue, after PHB consumption, making PHB supplementation interesting as a bioactive compound in other extraintestinal conditions, as 3-hydroxybutyrate has been reported to enhance brain and cognitive function, cardiac performance, appetite suppression and diabetes. Therefore, PHB could be postulated as an interesting non-polysaccharide antitumor prebiotic, paving the way towards its future use in functional foods.Among the matrices for enzyme immobilization, activated carbon has been standing out in immobilization processes due to its properties and to its characteristics that provide superficial modification by inserting new functional groups capable of binding the enzymes forming covalent bonds. In this study the effect of different modification methods of activated carbon (functionalization with genipin, metallization, metallization in the presence of chelating agent, and functionalization with glutaraldehyde) on efficiency of pepsin immobilization was evaluated. The effect of immobilization pH and the reaction medium on hydrolysis activity of bovine casein was also evaluated. SGC-CBP30 The functionalization of activated carbon using iron ions allowed an immobilization capacity of 98.93 mg·g-1, with immobilization efficiency greater than 99%, and enzyme activity of 2.30 U, which was higher than the other modifications, and closer to the enzyme in the native form activity (3.32 U). In general, the carbon surface modifications were responsible for forming more stable bonds between support and enzyme, improving its proteolytic activity (from 1.84 to 2.30 U) when compared to traditional immobilization methods by adsorption and covalent binding using glutaraldehyde (from 1.04 to 1.1 U).Here we developed a powerful tool for comprehensive data collection and mapping of molecular and elemental signatures in the Melanoma-bearing Libechov Minipig (MeLiM) model. The combination of different mass spectrometric methods allowed for detail investigation of specific melanoma markers and elements and their spatial distribution in tissue sections. MALDI-MSI combined with HPLC-MS/MS analyses resulted in identification of seven specific proteins, S100A12, CD163, MMP-2, galectin-1, tenascin, resistin and PCNA that were presented in the melanoma signatures. Furthermore, the ICP-MS method allowed for spatial detection of zinc, calcium, copper, and iron elements linked with the allocation of the specific binding proteins.Alternative ORFs in-frame with the known genes are challenging to reveal. Yet they may contribute significantly to proteome diversity. Here we focused on the individual expression of the SERPINA1 gene exon 5 leading to direct translation of alpha1-antitrypsin (AAT) C-terminal peptides. The discovery of alternative ways for their production may expand the current understanding of the serpin gene's functioning. We detected short transcripts expressed primarily in hepatocytes. We identified four variants of hepatocyte-specific SERPINA1 short transcripts and individually probed their potential to be translated in living cells. The long mRNA gave the full-length AAT-eGFP fusion, while in case of short transcripts we deduced four active SERPINA1 in-frame alternative ORFs encoding 10, 21, 153 and 169 amino acids AAT C-terminal oligo- and polypeptides. Unlike secretory AAT-eGFP fusion exhibiting classical AAT behavior, truncated AAT-fusions differ by intracellular retention and nuclear enrichment. Immunofluorescence on the endogenous AAT C-terminal epitope showed its accumulation in the cell nucleoli, indicating that short transcripts may be translated in vivo. FANTOM5 CAGE data on SERPINA1 suggest that short transcripts originate from the post-transcriptional cleavage of the spliced mRNA, initiated mainly from the hepatocyte-specific promoter. CONCLUSION Short SERPINA1 transcripts may represent a source for the direct synthesis of AAT C-terminal peptides with properties uncommon to AAT.Aromatic interaction plays a crucial role in controlling protein interaction by additives. Here we investigated the interaction of protein salting-in (solubilizing) additives with tryptophan (Trp), tyrosine (Tyr), indole, and proteins based on their fluorescence spectra. Five salting-in additives, i.e., arginine (Arg), urea, guanidine (Gdn), ethylene glycol (EG), and magnesium chloride (MgCl2), showed different effects on the fluorescence properties of Trp and Tyr. Arg significantly reduced fluorescence intensity of Trp and Tyr, as was the case for glycine to a lesser extent. MgCl2 and calcium chloride (CaCl2) showed little effect on the aromatic fluorescence spectra. Gdn also showed little effect on the aromatic fluorescence spectra of Trp and Tyr even at high concentrations. EG increased the aromatic fluorescence intensity of Trp and Tyr with blue-shifted emission wavelength. Urea enhanced fluorescence of Trp and Tyr without altering emission wavelength. These results indicate that the protein solubilizing additives interact with aromatic groups differently.
