Objective: Study specific Igg4 antibodies to milk proteins indexes in healthy babies living in different Russian megalopolises.Methods: The complex research of the specific Igg4 antibodies to milk proteins during cohort study of 259 healthy babies of the first year of life. Children lived in five Russian cities: 60 children in Moscow, 50 newborns – in Saint Petersburg, 55 children came from Kazan, 43 children lived in Khabarovsk and 51 – in Vladivostok. Non-competitive enzyme-linked immunosorbent assay was used to quantify specific Igg4 antibodies to cow milk proteins (CMP), beta-lactoglobulin (β-LG), alpha-lactalbumin (α-LA), casein and goat's milk protein (GM) in coprofiltratesResults: The highest frequency of the high Igg4 was discovered to CMP and goats’ milk was observed among children from Saint Petersburg during comparative assessment of the frequency of defining Igg4 to milk proteins in healthy newborns aged 2.5 months living in Moscow and Saint-Petersburg. The highest frequency of Igg4 increased rates to milk proteins among newborns from Kazan, Khabarovsk and Vladivostok was diagnosed during first three months of life on breastfeeding without any clinical symptoms of food intolerance. With age decrease of the frequency of specific Igg4 to milk proteins were observed among all babies from above-mentioned cities. By 8 month of life it made isolated cases.Conclusions: High frequency of increased Igg4 to milk proteins among 2 months old babies on breastfeeding was observed in the cities of Central and Far Eastern districts of Russian Federation. In this regard it can be supposed that Igg4s were got from mothers in the prenatal period and after birth through breastfeed. The presence of high frequency of the increased indexes of specific Igg4 to milk proteins probably was related to mothers’ nutrition habits during pregnancy and lactation periods.

Acute hellebore poisoning is characteristic for the Russian Federation because of the use of this plant for the treatment of alcoholism at home. The varying severity of clinical symptoms, which sometimes become lifethreatening, the lack of anamnestic reliable information about the use of hellebore and the difficulties of chemical and toxicological confirmation of its use complicate the diagnosis of acute poisoning, and do not allow timely medical care. In addition, there is no classification of hellebore poisoning in ICD-10, block (T51-T65), which also affects the assessment of the actual frequency of this acute intoxication. The purpose of this work is to clarify the number of acute hellebore poisoning in the Russian Federation. The analysis of medical records of patients hospitalized with acute hellebore poisoning in toxicological departments of a number of subjects of the Russian Federation for 2014 - 2018 was carried out. The dynamics of such acute poisoning over the specified period, the gender and age composition of victims, and the circumstances of poisoning were revealed. The relevance of developing methods of chemical and toxicological analysis for the determination of hellebore alkaloids is confirmed, which will increase the reliability of diagnosis and detection of cases of hellebore poisoning.

Among prevalent food allergies, cow milk allergy (CMA) is most common and may persist throughout the life. The allergic individuals are exposed to a constant threat due to milk proteins’ presence in uncounted food products like yogurt, cheese, and bakery items. The problem can be more severe due to cross-reactivity of the milk allergens in the food products due to homologous milk proteins of diverse species. This problem can be overcome by proper and reliable food labeling in order to ensure the life quality of allergic persons. Therefore, highly sensitive and accurate analytical techniques should be developed to detect the food allergens. Here, significant research advances in biosensors (specifically immunosensors and aptasensors) are reviewed for detection of the milk allergens. Different allergic proteins of cow milk are described here along with the analytical standard methods for their detection. Additionally, the commercial status of biosensors is also discussed in comparison to conventional techniques like enzyme-linked immunosorbent assay (ELISA). The development of novel biosensing mechanisms/kits for milk allergens detection is imperative from the perspective of enforcement of labeling regulations and directives keeping in view the sensitive individuals.

SummaryAn increased level of plasma thrombomodulin (TM) in α- and β- thalassaemia was demonstrated using an enzyme-linked immunosorbent assay (ELISA). Nonsplenectomized patients with β-thalassaemia/ haemoglobin E (BE) had higher levels of TM than splenectomized cases (BE-S). Patients with leg ulcers (BE-LU) were found to have the highest increase in TM level. Appearance of larger platelets in all types of thalassaemic blood was observed indicating an increase in the number of younger platelets. These data indicate that injury of vascular endothelial cells is present in thalassaemic patients.

AbstractGoat milk is a source of nutrition in difficult areas and has lesser allerginicity than cow milk. It is leading in the area for nutraceutical formulation and drug development using goat mammary gland as a bioreactor. Post translational modifications of a protein regulate protein function, biological activity, stabilization and interactions. The protein variants of goat milk from 10 breeds were studied for the post translational modifications by combining highly sensitive 2DE and Q-Exactive LC-MS/MS. Here we observed high levels of post translational modifications in 201 peptides of 120 goat milk proteins. The phosphosites observed for CSN2, CSN1S1, CSN1S2, CSN3 were 11P, 13P, 17P and 6P, respectively in 105 casein phosphopeptides. Whey proteins BLG and LALBA showed 19 and 4 phosphosites respectively. Post translational modification was observed in 45 low abundant non-casein milk proteins mainly associated with signal transduction, immune system, developmental biology and metabolism pathways. Pasp is reported for the first time in 47 sites. The rare conserved peptide sequence of (SSSEE) was observed in αS1 and αS2 casein. The functional roles of identified phosphopeptides included anti-microbial, DPP-IV inhibitory, anti-inflammatory and ACE inhibitory. This is first report from tropics, investigating post translational modifications in casein and non-casein goat milk proteins and studies their interactions.

Background: Human milk contains antibodies against Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) following Coronavirus Disease 2019 (COVID-19). These antibodies may serve as protection against COVID-19 in infants. However, the evolution of these human milk antibodies over time is unclear. Research Aim: To elucidate the evolution of immunoglobulin A (IgA) against SARS-CoV-2 in human milk after a SARS-CoV-2 infection. Methods: This longitudinal follow-up study included lactating mothers ( N = 24) who had participated in the COVID MILK study. To assess the evolution of SARS-CoV-2 antibodies, serum and human milk samples were collected 14–143 days after the onset of clinical symptoms related to COVID-19. Enzyme-Linked ImmunoSorbent Assay was used to detect antibodies against the ectodomain of the SARS-CoV-2 spike protein. Results: SARS-CoV-2 antibodies remain present up to 5 months (143 days) in human milk after onset of COVID-19 symptoms. Overall, SARS-CoV-2 IgA in human milk seems to gradually decrease over time. Conclusion: Human milk from SARS-CoV-2 convalescent lactating mothers contains specific IgA antibodies against SARS-CoV-2 spike protein up to at least 5 months post-infection. Passive viral immunity can be transferred via human milk and may serve as protection for infants against COVID-19.

Abstract The aim of the present study was to investigate the occurrence of N. caninum associated with abortions of dairy cattle from Santa Catarina state, southern Brazil by using enzyme-linked immunosorbent assay (ELISA), immunohistochemistry (IHC), and polymerase chain reaction (PCR). Blood from dairy cows that aborted along with intrathoracic fluid and tissue samples (brain, heart, liver, and lung) from their fetuses were collected and used for serology; PCR, histopathological, and immunohistochemistry (IHC) evaluations were also conducted. Twenty-one cows (51.2%) out of 41, and eight fetuses (26.7%) out of 30 were ELISA (HerdCheck, IDEXX) positive for N. caninum. Dams > 36 months of age had a higher risk of being serum positive than younger animals. PCR and IHC revealed that 38.8% (14/36) and 25.0% (9/36) of the fetuses were positive for N. caninum, respectively for each of the tests. Seropositive cows had a higher frequency of fetuses that were also positive by either intrathoracic fluid, PCR, or IHC. In summary, the present study observed a high frequency of N. caninum in abortions from dairy cows from southern Brazil, with a higher N. caninum prevalence found in cows that were older than 36 months. In addition, serology, PCR, and IHC should be used all together for better diagnosis of neosporosis in cattle.

Enterotoxin Production

The aim of this study was to compare Bacillus cereus growth rates and diarrhoeal enterotoxin production in raw and pasteurized goat, sheep, and cow milk in terms of storage conditions. Milk samples were inoculated with B. cereus (CCM 2010), which produces diarrhoeal enterotoxins. Enterotoxin production was tested by ELISA (Enzyme-Linked Immunosorbent Assay), and the count of B. cereus was determined by the plate method. With raw cow milk, B. cereus growth and enterotoxin production can be completely suppressed; in raw goat and sheep milk, enterotoxin was produced at 22 °C. In pasteurized cow, goat, and sheep milk, the B. cereus count increased under all storage conditions, with more rapid growth being observed at 15 °C (sheep milk) and 22 °C (cow and goat milk). Enterotoxin presence was detected at 15 °C and 22 °C, and with pasteurized cow milk also at 8 °C. Our model experiments have determined that B. cereus multiplication and subsequent enterotoxin production depend on storage temperature and milk type.
