Lactoferrin chimera (LFchimera), a heterodimeric peptide containing lactoferrampin (LFampin265-284) and a part of lactoferricin (LFcin17-30), possesses a broad spectrum of antimicrobial activity. However, there is no report on the inhibitory effects of LFchimera against multispecies oral biofilms. This study aimed to determine the effects of LFchimera in comparison to chlorhexidine digluconate (CHX) and minocycline hydrochloride (MH), on in vitro multispecies biofilms derived from subgingival plaque of periodontitis patients harboring Aggregatibacter actinomycetemcomitans...

Candida albicans is a minor component of the oral microbiota and an opportunistic pathogen that takes advantage of the immunocompromised host and causes oral mucositis and oral candidiasis. This organism is able to undergo phenotypic modification from a yeast to hyphae growth phase, one of the key arsenals for immune cell evasion, tissue invasion and biofilm formation. The latter property coupled with overgrowth and immune compromising factors such as HIV/AIDS, cancer treatments, organ transplantation, diabetes, corticosteroid use, dentures, and broad-spectrum antibiotic use have modified the fungus from a normal component of the microflora to a foe of an oral cavity and resulting in reduced sensitivity towards commonly utilised antifungal agents...

The balance between free radicals and antioxidants is an important factor for maintaining health and slowing disease progression. The use of antioxidants, particularly natural antioxidants, has become an important strategy for dealing with this cause of widespread diseases. Natural antioxidants have been used as therapeutic tools against many diseases because they are safe, effective, and inexpensive and are among the most commonly used adjuvants in the treatment of several diseases. Camel whey protein (CWP) is considered a strong natural antioxidant because it decreases oxidative stress, enhances immune system function, and increases glutathione levels...

Calprotectin and lactoferrin are released by the gastrointestinal tract in response to infection and mucosal inflammation. Our objective was to assess the usefulness of quantifying faecal lactoferrin and calprotectin concentrations in Clostridium difficile infection (CDI) patients with or without free toxins in the stools. We conducted a single-centre 22-month case-control study. Patients with a positive CDI diagnosis were compared to two control groups: group 1 = diarrhoeic patients negative for C. difficile and matched (1:1) to CDI cases on the ward location and age, and group 2 = diarrhoeic patients colonised with a non-toxigenic strain of C...

Lactoferrin in commercial supplements is known to exert anti-viral and anti-allergic effects. However, this is the first study to evaluate the induction of allergic airway inflammation in NC/Nga mice. Human lactoferrin was administered intraperitoneally with aluminum oxide for sensitization. Five days later, lactoferrin was inoculated intranasally for 5 days, and then on the 12th day, the single inoculation of lactoferrin intranasally was performed as a challenge. On the 13th day, airway hypersensitivity was assessed (AHR), a bronchoalveolar fluid (BALF) cell analysis was conducted, serum IgE and serum lactoferrin-specific IgG and IgE levels as well as the mRNA expression levels of cytokines and chemokines in the lung were measured, and a histopathological analysis of the lung was performed...

Fusion of therapeutic proteins with the antibody Fc domain is a strategy widely applied to increase protein half-life in plasma. In our previous study, we generated a recombinant human lactoferrin (hLF)-immunoglobulin G1 Fc fusion protein (hLF-hinge-CH2-CH3) with improved stability, biological activity, and pharmacokinetics ( Shiga , Y. et al. Eur J Pharm Sci. , 2015 , 67 , 136 - -143 ). However, the Fc domain in fusion proteins can potentially induce antibody-dependent and complement-dependent cytotoxicity and serious side effects...

The risk for a dairy cow to acquire new intramammary infections is high during the transition from lactation to the dry period, because of udder engorgement and altered immune functions. Once the gland is fully involuted, it becomes much more resistant to intramammary infections. Therefore, strategies to depress milk yield before drying-off and accelerate the involution process after drying-off could be beneficial for udder health. The objective of this study was to assess the effect of photoperiod manipulation and melatonin feeding from 14 d before to 14 d after drying-off on the speed of the involution process...

OBJECTIVE: Formula feeding is associated with compromised intestinal health in preterm neonates compared with maternal milk, but the mechanisms behind this are unclear. We hypothesized that the use of maltodextrin and whey protein concentrates (WPCs) with reduced bioactivity due to thermal-processing are important factors. METHOD: Ninety-two caesarean-delivered preterm pigs were fed increasing doses of formulas for 5 days (24-120 mL/kg/d). In Experiment 1, four groups of pigs (n = 15-16) were fed lactose- or maltodextrin-dominant formulas (lactose/maltodextrin ratios 3:1 or 1:3, respectively), containing WPC with either high or low levels of IgG (WPC1 or WPC2, respectively)...

Targeted delivery of drugs to the brain is challenging due to the restricted permeability across the blood brain barrier (BBB). Gliomas are devastating cancers and their positive treatment outcome using Temozolomide (TMZ) is limited due to its short plasma half-life, systemic toxicity and limited access through the blood-brain barrier (BBB). Nanoparticles made of Lactoferrin (Lf) protein, have been shown to enhance the pharmacological properties of drugs. Here, we report the specific ability of Lf nanoparticles to cross BBB and target over-expressed Lf receptors on glioma for enhanced TMZ delivery...

INTRODUCTION: Human milk immune components are unique and important for the development of the newborn. Milk processing at the Human Milk Banks (HMB), however, causes partial destruction of immune proteins. The objective of this study was to determine the effects that heating during the milk processing procedure at the HMB had on the concentrations of IgA, IgM, and lactoferrin at three critical points in time. MATERIALS AND METHODS: Fifty milk samples (150 mL) were collected from voluntary donors at the HMB at the Hospital Nacional Pedro de Bethancourt, located in Antigua Guatemala...

BACKGROUND: Histologic assessment of mucosal disease activity has been increasingly used in clinical trials of treatment for Crohn's disease. However, the operating properties of the currently existing histologic scoring indices remain unclear. OBJECTIVES: A systematic review was undertaken to evaluate the development and operating characteristics of available histologic disease activity indices in Crohn's disease. SEARCH METHODS: Electronic searches of MEDLINE, EMBASE, PubMed, and the Cochrane Library (CENTRAL) databases from inception to 20 July 2016 were supplemented by manual reviews of bibliographies and abstracts submitted to major gastroenterology meetings (Digestive Disease Week, United European Gastroenterology Week, European Crohn's and Colitis Organisation)...

Current treatments for Parkinson's disease (PD) are limited, partly due to the difficulties posed by the blood brain barrier (BBB) when delivering drugs to the brain. Herein, we explore the feasibility and efficacy of functional single-walled carbon nanotubes 'CAR' (SWCNT-PEGs-Lf) which carry and target-deliver dopamine (DA) to the brain in PD mice for treatment. SWCNTs can penetrate the cell-membrane remarkably, with the characteristics including high drug-loading and pH-dependent therapeutic unloading capacities...
