Quantitative proteomics analysis revealed different proteome profiles for colostrum exosomes and milk exosomes. The functional analysis highlighted pathways related to the regulation of homeostasis to be upregulated in colostrum exosomes, and pathways such as endothelial cell development and lipid metabolism to be upregulated in mature milk exosomes. This study endorses the importance of exosomes as active biocomponents of milk and provides knowledge for future studies exploring their role in the regulation of immunity and growth of the newborn. SIGNIFICANCE The identified functional proteome and protein-protein interaction networks identified in our study help to elucidate the role of milk exosomes in different lactation periods. The results generated herein are of relevance for the basic understanding of their impact on the infant's development but also for bringing forward the manufacturing of milk replacers.Better understanding of antibody responses against SARS-CoV-2 after natural infection might provide valuable insights into the future implementation of vaccination policies. Longitudinal analysis of IgG antibody titers was carried out in 32 recovered COVID-19 patients based in the Umbria region of Italy for 14 months after Mild and Moderately-Severe infection.Two FDA-approved immunoassays against SARS-CoV-2 Nucleocapsid protein (NCP) and anti-spike-receptor binding domain (S-RBD) were used for sequential serological tests at different time points. see more The demographics,clinical history and symptom profile associated with the magnitude and longevity of antibody responses were also analyzed. Anti-S-RBD IgG persisted in 96.8% (31 of 32) subjects at 14 months. Patients reporting loss of smell and taste during the clinical course of the disease developed significantly higher antibody titers. Anti-NCP IgG seronegative patients(n=7) at 10 months, tested positive for anti-S-RBD IgG at 12,13 and 14 months emphasizing on a higher false-negative rate for NCP protein-based antibody assays. This study also highlights the importance of adopting specific immunoassays for routine estimation of antibody titers and the decreased rate of re-infections in recovered patients.This study aimed to analyse the efficacy of haploidentical donor (HID) haematopoietic stem cell transplantation as a first-line treatment for severe aplastic anaemia (SAA) with high-risk factors (infection or very severe aplastic anaemia,VSAA) in patients who lack an HLA-matched sibling donor (MSD). The patients with infection were treated with anti-infection therapy, and allogeneic haematopoietic stem cell transplantation (HSCT) was carried out after the infection being effectively controlled was in accordance with the stable infection (SI) standard. A total of 44 SAA patients receiving MSD transplantation (n=19) and HID transplantation (n=25) were included in this study. There was no significant difference in neutrophil engraftment between the two groups [MSD vs. HID, 19 (11-38) vs. 22 (15-47).P=0.241], and the difference in platelet engraftment was statistically significant [MSD vs. HID, 11(7-33) vs. 20 (12-69), P=0.034]. The HID group exhibited a higher incidence of grade II-IV acute graft-versus-host disease (aGVHD) (HID vs. MSD, 48.0% vs10.5%, P=0.034)and a higher incidence of chronic GVHD (cGVHD) than the MSD group (64.0% vs. 21.1%, P=0.026). There was no significant difference between overall survival (OS) following HID and MSD transplantation (84.0% vs. 89.5%, P=0.664) and failure-free survival (FFS)(80.0% vs. 84.2%, P=0.965). The interval from diagnosis to transplantation (>50d) and ECOG (>2) were independent factors associated with OS and FFS. HID HSCT may be an effective and safe option for SAA patients with high-risk factors who lack an MSD.
Human papillomavirus (HPV) infection is one of the major health concerns of women in developing countries. This study gives an insight into the prevalence and genotype distribution of HPV infection and compares it with Pap smear results among Iranian women.

In this study, 12,076 Iranian women underwent routine examination from November 2016 to November 2018 using HPV Direct Flow CHIP System for HPV DNA typing. Cytology methods were also undertaken for 5,138 samples.

Overall HPV prevalence was calculated at 38.68%. The most frequent HPV types were HPV 6, 16, 11, 62/81, 52, and 54, respectively; and, the most high-risk HPV types were HPV 16, 52, 18, 39, 31, and 51. These two groups represent about half of all HPV types detected-47% and 55%, respectively. Among individuals who underwent cytological tests, 135 individuals (2.63%) were cytologically positive. In this group, 81 individuals (60%) were HPV positive as well, 62 (76%) of whom were HR-HPV positive and among them, the most frequent type was HPV 16 (34%).

This study highlights the urgent need for public education and also early diagnosis using HPV screening tests to prevent cervical cancer.

. Serology tests play an important role in assessing the immune system's response to a previous SARS-CoV-2 infection or to vaccination. In Venezuela, before and after receiving the Sputnik V vaccine, we evaluated the IgG antibody response against the nucleocapsid protein (NP) and the receptor-binding domain (RBD) of the spike protein of SARS-CoV-2 in a cohort of 86 individuals.

. Antibody responses against NP and RBD were determined with an ELISA just before, 3 weeks after the first and 6 weeks after the second dose of the vaccine.

Before vaccination, 59 individuals were seronegative and the other 27 were seropositive for SARS-CoV-2 antigens NP and/or RBD. Of the seronegative cohort, 42% did not develop a measurable IgG immune response against RBD after the first vaccine dose but all (100%) had a strong IgG response after two vaccine doses. All seropositive individuals developed a strong IgG antibody response against RBD after the first vaccine dose, with antibody levels approximately 40% higher than the seronegative individuals who had received two doses. Moreover, the previously seropositive subjects showed no significant increase in IgG antibody response against RBD after the second vaccine dose.

We demonstrated that two dose of the Sputnik V vaccine triggers antibody response in all individuals of this study. The second vaccine dose of Sputnik V has no impact on the IgG response for who were seropositive for SARS-CoV-2 antigens prior to vaccination.

Residues 90-94 of SU are considered as a Nrp1 binding site, and our previous results show that an SU peptide consisting of residues 85-94 can bind directly to the Nrp1 b1 domain with a binding affinity of 7.4 μM. Therefore, the SU peptide is expected to be a good model to investigate the SU-Nrp1 interaction. Recently, the N93D mutation in the Nrp1 b1 binding region of the SU was identified in symptomatic patients with HTLV-1 infections in the Brazilian Amazon. However, it remains unclear how the SU-N93D mutation affects Nrp1 b1 binding. To elucidate the impact of the substituted Asp93 of SU on Nrp1 b1 binding, we analyzed the interaction between the SU-N93D peptide and Nrp1 b1 using isothermal titration calorimetry and nuclear magnetic resonance. The SU-N93D peptide binds directly to Nrp1 b1 with a binding affinity of 3.5 μM, which is approximately two-fold stronger than wild-type. This stronger binding is likely a result of the interaction between the substituted residue Asp93 of the N93D peptide and the four residues Trp301, Lys347, Glu348, and Thr349 of Nrp1 b1. Our results suggest that the interaction of SU Asp93 with the four residues of Nrp1 b1 renders the high affinity of the N93D mutant for Nrp1 b1 binding during HTLV-1 entry.Cadmium (Cd) is a non-essential metal that is highly toxic to all living forms, characterized by an extremely high affinity for thiol (SH) groups. The aim of this work was to identify and experimentally verify metallothionein gene and to analyze the role of biological thiols in stress induced by short-term Cd exposure in Ostrinia nubilalis, one of the most important corn pests. The coding region of a metallothionein (MT) gene in O. nubilalis was identified, encoding protein, OnMT1, which contains 46 amino acids, including 12 cysteine residues, and has no aromatic amino acids. Phylogenetic analysis revealed that OnMT1 clustered together with metallothionein from Bombyx mori. Structural bioinformatics analysis strongly suggests that OnMT1 is a metallothionein with affinity for multiple transition metals. Further, in order to elucidate the role of biological thiols, O. nubilalis L5 larvae were exposed to increasing Cd concentrations in diet (6.85, 41.71, 77.35 mg kg-1) during a 48 h period, after which Cd concentration in larvae was measured (3.50, 12.02, 47.37 mg kg-1, respectively). Due to short-term Cd exposure, concentration of free protein SH groups and relative expression of OnMT1 and thioredoxin (Trx) genes was elevated, while the reduced glutathione content remained unchanged. The presented results provide evidence that OnMT1 plays a role in Cd detoxification and homeostasis, and confirm the importance of biological thiols, especially OnMT1 and Trx, in the early response of O. nubilalis to Cd poisoning, indicating interaction between Cd and thiol-linked redox reactions. Insects provide valuable insight into molecular adaptations to metals.Berberine is a famous alkaloid extracted from Berberis plants and has been widely used as medications and functional food additives. Recent studies reveal that berberine exhibits neuroprotective activity in animal models of Parkinson's disease (PD), the second most prevalent neurodegenerative disorders all over the world. However, the actual site of anti-PD action of berberine remains largely unknown. To this end, we employed a fluorescently labeled berberine derivative BBRP to investigate the subcellular localization and blood brain barrier (BBB) permeability in a cellular model of PD and zebrafish PD model. Biological investigations revealed that BBRP retained the neuroprotective activity of berberine against PD-like symptoms in PC12 cells and zebrafish, such as protecting 6-OHDA induced cell death, relieving MPTP induced PD-like behavior and increasing dopaminergic neuron loss in zebrafish. We also found that BBRP could readily penetrate BBB and function in the brain of zebrafish suffering from PD. Subcellular localization study indicated that BBRP could rapidly and specifically accumulate in mitochondria of PC12 cells when it exerted anti-PD effect. In addition, BBRP could suppress accumulation of Pink1 protein and inhibit the overexpression of LC3 protein in 6-OHDA damaged cells. All these results suggested that the potential site of action of berberine is mitochondria in the brain under the PD condition. Therefore, the findings described herein would be useful for further development of berberine as an anti-PD drug.
