Meconium concentrations of naturally accumulated ceruloplasmin (CER), lactoferrin (LF), and neutrophil gelatinase-associated lipocalin (NGAL) and their relationships considered as a panel of acute phase proteins could be used for the assessment of fetal homeostasis. CER, LF and NGAL concentrations were measured using ELISA kits in meconium portions (n=80) collected from 19 healthy neonates. The coefficients of variation (CV) of the meconium LF (1.77) and NGAL (1.26) were about 2-fold higher than that of CER (0...

The best studied substances in bovine colostrum are the immunoglobulins. They are absorbed in the small intestine of the neonate by pinocytosis. The Fc-receptor is not highly involved in this process in calves compared to other species. However, this receptor plays a crucial role in the transport of immunoglobulins from the circulation of the dam to the udder and, therefore, into the colostrum. During colostrogenesis, which starts up to 8 weeks prior to parturition, up to 500 g of immunoglobulins are transferred daily by this process...

BACKGROUND: Clostridium difficile is a gram-positive, anaerobic spore-forming, toxin-producing bacillus, which is one of the most common causes for health care-associated infections. High colonization rates in clinically asymptomatic neonates and infants have been described, although most studies go back to the early 1980 and 1990s, and were carried out in term and late preterm infants. OBJECTIVES: The aim of our study was to determine both the impact and time course of C...

Background: In Crohn's disease (CD) a small bowel study-in addition to colonoscopy-is considered necessary for diagnosis/staging. In this study we re-examined the role of capsule endoscopy (CE), colonoscopy, imaging tests [magnetic resonance enterography/computed tomographic enterography (MRE/CTE)], and inflammatory markers [fecal lactoferrin and C-reactive protein (FL/CRP)] in CD patients who had undergone intestinal resection and in those who never had surgery. Methods: In this retrospective study 43 consecutive patients underwent CE because of staging/symptoms unexplained by colonoscopy/imaging...

Over the last decades, poultry industry faced to the rapid emergence of multidrug-resistant bacteria as a global concern. Antimicrobial peptide (AMPs) known as potential antibiotic alternative and were considered as a new antimicrobial agent. Current methods of production and purification of AMPs have several limitations such as: costly, time-consuming and killing the producing host cells in recombinant form. In the present study, a chimeric peptide derived from camel lactoferrin was produced in Escherichia coli periplasmic space using a pET-based expression system and its antibacterial activity was determined on some avian pathogens in vitro...

Immature B cells are susceptible to apoptosis due to ligation of surface immunoglobulin receptors. The WEHI 231 cell line represents a useful model to study the mode of action of factors preventing apoptosis. In this work we investigated the protective effects of multi-species lactoferrins in anti-mouse Ig-induced WEHI 231 cell death. Bovine milk-derived lactoferrin (bLF), recombinant human lactoferrin expressed in Chinese hamster ovary cells - rhLF(CHO) or in human endothelial kidney cells - rhLF(HEK), and recombinant mouse lactoferrin expressed in Chinese hamster ovary cells - rmLF(CHO), were used...

Current research efforts on neurological diseases are focused on identifying novel disease biomarkers to aid in diagnosis, provide accurate prognostic information and monitor disease progression. With advances in detection and quantification methods in genomics, proteomics and metabolomics, saliva has emerged as a good source of samples for detection of disease biomarkers. Obtaining a sample of saliva offers multiple advantages over the currently tested biological fluids as it is a non-invasive, painless and simple procedure that does not require expert training or harbour undesirable side effects for the patients...

The excess from fecal samples submitted to a centralized laboratory in Roanoke, Virginia for routine C. difficile testing was used for this research study. We tested all samples, including any formed samples usually not assayed in diagnostic laboratories. Our first aim was to rank ribotypes by their frequency. Between 2007 and 2013, fluoroquinolone resistant 027 (027FQR), a multi-drug resistant ribotype, was 32% of 3118 Clostridium difficile isolates and the most common of 128 ribotypes. 027FQR was in 45% of cytotoxin positive but only 17% of cytotoxin negative fecal samples (p = 0...

Ascitic neutrophils from cirrhotic patients with spontaneous bacterial peritonitis (SBP) exhibit an impaired oxidative burst that could facilitate bacterial infection. However, the influence of the cell-free ascitic fluid of these patients on neutrophil function has not been investigated. To analyze this influence, we determined the ascitic levels of cytokines, resistin, and lactoferrin and their association with neutrophil function, disease severity score, and SBP resolution. We analyzed NETosis induction by microscopy and oxidative burst by the flow cytometry of healthy neutrophils cultured in ascitic fluid from cirrhotic patients with sterile ascites (SA) and with SBP before and after antibiotic treatment...

Lactoferrin is a secretory protein with various physiological functions. Bovine lactoferrin has been demonstrated to alleviate psychological stresses in rats, but this effect in humans has not yet been assessed. The present study aimed to investigate the changes in psychological stress markers following a calculation task, with either lactoferrin or a placebo orally administered prior to the task. A total of 16 healthy female college students visited Juntendo University, Inzai, Japan following an overnight fast...

Clinical trials require valid outcome measures to assess the therapeutic benefit of investigational agents. Recently, regulatory authorities have mandated the use of patient-reported outcomes in combination with an objective measure of disease activity as primary outcome measures in inflammatory bowel disease trials. Endoscopy has commonly fulfilled the latter role; however, due to the costs and complexity of these assessments, interest has emerged in the use of noninvasive biomarkers. The role of C-reactive protein, fecal calprotectin, and fecal lactoferrin in clinical research is discussed...

Current scientific consensus about the physiopathology in the progression from severe sepsis to septic shock and death focuses on myocardial contractile dysfunction. Nevertheless, objective parameters to establish a pathological correlate of a fatal outcome are lacking; then a cause of death due to sepsis can remain an unsolved problem. We first reviewed all death cases recorded at our institutions during the period from 2007 until 2015. Then, we conducted a retrospective study of a selected autopsy series of people who had received "sepsis" as cause of death...

Lactoferrin (Lf) exerts anti-cancer effects on glioma, however, the exact mechanism remains unclear. Despite possessing a nuclear localization sequence (NLS), Lf was found to allocate only in the cytoplasm of glioma 261. Lf was therefore loaded into nuclear and cytoplasmic targeted nanoparticles (NPs) to determine whether nuclear delivery of Lf would enhance its anti-cancer effect. Upon treatment with 300 and 800 µg/mL Lf loaded chitosan NPs, nuclear targeted Lf-NPs showed 1.3 and 2.7 folds increase in cell viability, whereas cytoplasmic targeted Lf-NPs at 300 µg/mL decreased cell viability by 0...

Visceral Leishmaniasis (VL), caused by the protozoan parasite Leishmania donovani, is a potentially fatal disease. The only orally bioavailable drug miltefosine is toxic and the effective liposomal Amphotericin B (AmBisome) is limited by its prohibitive cost and requirement for parenteral administration. Therefore, finding a new potential drug candidate and an alternative delivery system is imperative. We report that Betulinic acid (BA), a pentacyclic triterpenoid from Betula alba bark, was loaded onto uniformly spherical PLGA nanoparticles (BANPs; diameter 187...
