Stage of Gestation at Porcine Epidemic Diarrhea Virus Infection of Pregnant Swine Impacts Maternal Immunity and Lactogenic Immune Protection of Neonatal Suckling Piglets
In this study, we infected pregnant first parity gilts in their first, second and third trimesters of gestation with PEDV to determine the impact of stage of gestation on generation of maternal B-cell immunity, the gut-MG-sIgA axis and lactogenic immune protection in PEDV challenged piglets. Our goal was to identify innate and adaptive immune factors during pregnancy that influence lymphocyte trafficking, in addition to immune correlates of lactogenic immune protection in neonatal suckling piglets. Understanding the impact of stage of gestation at PEDV infection or exposure on maternal immunity will allow more precise maternal vaccination protocols to target the time when the animal is most immunologically responsive. Optimizing vaccine efficacy for gestating and lactating animals will enhance lactogenic immunity in neonates and decrease morbidity and mortality associated with neonatal enteric disease. Results Overall Summary of Results and Significance for the Major Immune and PEDV Protection Parameters Assessed An overall summary of the statistically significant results (Table 1) illustrates that PEDV infection of gilts at different stages of gestation (Figure 1) affects multiple maternal systemic immune parameters prepartum, including natural killer (NK) cells, cytokines, B cells, and PEDV Abs and antibody secreting cells (ASCs). In addition, significant postpartum effects on lactogenic immune parameters in colostrum and milk were observed including significantly increa...

CHARLESTON, S.C. - A charity and a water supplier on Oct. 4 moved in South Carolina federal court for permission to amend their complaint against the United States related to groundwater contamination from aqueous film forming foam (AFFF) to add claims against new parties including the 3M Co., Tyco Fire Products LP and others (Security Water District, et al. v. United States of America [In re: Aqueous Film Forming Foam], No. 19-2187, MDL 18-2873, D. S.C.).

ConclusionThe ease of mobilization, superior blood supply and minimal donor site morbidity make it an ideal flap and a reliable alternative when other techniques fail.
Discussion Female-to-male transgender patients often undergo chest contouring as their initial gender affirmation surgery. As the surgical treatment of gender dysphoria continues to grow, it is imperative for plastic surgeons to understand the surgical options and associated outcomes for transmasculine top surgery. Future research is needed to improve patient selection, surgical decision making, and patient-reported outcomes for different chest contouring techniques. In addition, there is a significant knowledge gap for the ideal nipple-areolar complex shape, size, and location.
l;nke G Abstract Mononuclear phagocytes, including monocytes and macrophages, are a central component of the host's innate immune system designated to protect against invading pathogens. However, these cells do not only interact with various parts of the innate and adaptive immune system, but also fulfill indispensable duties during the control of tissue homeostasis and organ function. Moreover, macrophages are crucially involved in tissue remodeling and repair in response to damage. Simultaneously, mononuclear phagocytes might also contribute to the pathogenesis of various inflammatory and autoimmune diseases. In...
Abstract Neutralizing antibodies against human immunodeficiency virus subtype 1 (HIV-1) bind to its envelope glycoprotein (Env). Half of the molecular mass of Env is carbohydrate making it one of the most heavily glycosylated proteins known in nature. HIV-1 Env glycans are derived from the host and present a formidable challenge for host anti-glycan antibody induction. Anti-glycan antibody induction is challenging because anti-HIV-1 glycan antibodies should recognize Env antigen while not acquiring autoreactivity. Thus, the glycan network on HIV-1 Env is referred to as the glycan shield. Despite the challenges pre...
