Effect of lactation induction on milk production and composition, oxidative and antioxidant status, and biochemical variables

This study aimed to induce lactation in Lacaune sheep and to verify its influence on milk production and composition, oxidative/antioxidant profile, and biochemical variables in serum and milk. A group of ewes (group A, n = 7) was induced with estradiol (0.5 mg/kg body weight (BW)) and progesterone (1.25 mg/kg BW) on days 1 to 7, bovine somatotropin (BST; 250 mg/animal) on days 11 and 40, as well as dexamethasone (16 mg/day) on days 19, 20, and 21. For comparison, another group of pregnant ewes was used as control (group B, n = 5). Blood and milk samples were collected for biochemical analysis, oxidative/antioxidant profile analysis, and determination of individual volume and chemical composition. The hormonal protocol was effective to induce lactation; however, milk production was 79 % lower than the control group. Milk fat, protein, and total solids were significantly lower (p

However, the mechanisms of action underlying the transgenerational toxicity of DEHP are not understood. Therefore, this study determined the effects of prenatal and ancestral DEHP exposure o...

SUMMARY Since the outbreak of a cluster of patients with pneumonia of unknown cause in Wuhan, Hubei Province, China, in December 2019, the disease was later officially named coronavirus disease 2019 (COVID-19) caused by the novel severe acute respiratory syndrome coronavirus (SARS-CoV-2), quickly spreading globally. Pregnant women and children are particularly vulnerable during disasters and emergencies. Comprehensive and applicable emergency preparedness and response are definitely important methods to prevent and contain the COVID-19 pandemic. The rational allocation of pharmaceutical resources plays an important role in...

CONCLUSION Further studies with a great number of cases are warranted to elucidate whether the virus may be vertically transmitted to the fetus and if any maternal conditions can influence that. Our findings seem to demonstrate that vertical transmission is possible but quite unusual.RESUMO OBJETIVO Revisar as evid ências científicas atuais sobre a transmissão vertical relacionada à infecção pelo novo coronavírus 2019 (COVID-19). MÉTODOS Uma revisão integrativa foi realizada por dois pesquisadores independentes, com base na literatura disponível nas bases...

Today's open access paper discusses the impact of mitochondrial DNA damage on female reproductive capabilities. Mitochondria are the power plants of the cell, a herd of hundreds of organelles responsible for packaging the chemical energy store molecule ATP, used to power cellular processes. They are additionally deeply integrated into many core cellular processes. Mitochondria are the evolved descendants of ancient symbiotic bacteria: they carry their own small genome, the mitochondrial DNA, and replicate like bacteria. Unfortunately this mitochondrial DNA is more vulnerable and less proficiently repaired than the nuclear ...

By Mabingue Ngom and Shoko ArakakiNEW YORK, Sep 21 2020 (IPS) The countries of Central Sahel—Burkina Faso, Mali, and Niger—face an unprecedented crisis, marked by violent extremism, forced displacement, and rising insecurity. The sharp increase in armed attacks on communities, health centres, schools and other public institutions and infrastructure has disrupted livelihoods and access to social services. The impact on affected people is devastating. As the international community responds to the crisis, we must meet immediate needs, and invest in long-term development. We must also work on shaping peace togeth...

Over the past few months, we have all seen the results of significant disruption to daily life due to the COVID-19 pandemic, high levels of unemployment, and civil unrest driven by chronic racial injustice. These overlapping waves of societal insult have begun to bring necessary attention to the importance of health care disparities in the United States. Direct links between stress, discrimination, racial injustice, and health outcomes occurring over one’s lifespan have not been well studied. But a recently published article in the journal Hypertension has looked at the connection between discrimination and increased...
