BACKGROUND: Ocular toxoplasmosis (OT) is a common cause of posterior uveitis worldwide. The diagnosis of OT is based on clinical findings, but in most cases, laboratory tests are required to confirm the aetiology, especially when other diseases are suspected. The aim of this study was to evaluate which methods, between the Goldmann-Witmer coefficient (GWC) and immunoblotting (IB) with both IgG and IgA, in aqueous humour (AH) samples, can be the most sensitive to diagnose OT, in current practice, especially in the first three weeks...

The liver has unique microenvironment which is known to induce tolerance of cytolytic CD8+ T cells to hepatic and extra hepatic antigens, resulting in persistence of infection of the liver by the hepatitis B and C viruses. However, under some conditions, functional immune responses can be elicited in the liver in particular to show preferential retention of activated CD8+ T cells. It is not clear whether this retention depends on the type of the exogenous immunostimulatory or the endogenous innate immune cells...

BACKGROUND: Oxytocin (OT) is a social hormone that may help researchers understand how nurse-guided interventions during initial infant hospitalization, such as supporting human milk expression, promoting comforting touch, and reducing exposure to stressors, affect preterm brain development. PURPOSE: To determine whether factors related to human milk, touch, or stressor exposure are related to plasma OT trajectories in premature infants. METHODS: Plasma from 33 premature infants, born gestational ages 25 to 28 6/7 weeks, was collected at 14 days of life and then weekly until 34 weeks' corrected gestational age (CGA)...

The association between excessive training sessions (i.e., overtraining/OT) and periods of inadequate recovery is linked to the nonfunctional overreaching (NFOR) state, which is defined as an unexplained decrement or stagnation of performance. The cytokine hypothesis of OT considers that pro-inflammatory cytokines are responsible by the NFOR state-induced performance decrement. Investigations using rodent models of OT verified increased levels of pro-inflammatory cytokines in hypothalamus, liver, serum and skeletal muscle samples...

AIM: Maintaining normothermia is a tenet of neonatal care. However, neonatal thermal care guidelines applicable to intra-hospital transport beyond the neonatal intensive care unit (NICU) and during surgery or magnetic resonance imaging (MRI) are lacking. The aim of this study is to determine the proportion of infants normothermic (36.5-37.5°C) on return to NICU after management during surgery and MRI, and during standard clinical care in both environments. METHODS: Sixty-two newborns requiring either surgery in the operating theatre (OT) (n = 41) or an MRI scan (n = 21) at the Royal Children's Hospital (Melbourne) NICU were prospectively studied...

Short peptides are the minimal modality of antigen recognized by cellular immunity and are therefore considered a safe and highly specific source of antigen for vaccination. Nevertheless, successful peptide immunotherapy is limited by the short half-life of peptide antigens in vivo as well as their weak immunogenicity. We recently reported a vaccine strategy based on dendritic cell-recruiting Mesoporous Silica Rod (MSR) scaffolds to enhance T-cell responses against subunit antigen. In this study, we investigated the effect of covalently conjugating peptide antigens to MSRs to increase their retention in the scaffolds...

Expansion and death of effector CD8 T cells are regulated to limit immunopathology and cells that escape contraction go on to generate immunological memory. CD44, a receptor for the extracellular matrix component hyaluronan, is a marker of activated and memory T cells. Here, we show with a murine model that the increase in CD44 expression and hyaluronan binding induced upon CD8 T cell activation was proportional to the strength of TCR engagement, thereby identifying the most strongly activated T cells. When CD44-/- and CD44+/+ OT-I CD8 T cells were adoptively transferred into mice challenged with Listeria-OVA, there was a slight increase in the percentage of CD44+/+ cells at the effector site...

Poly(lactic-co-glycolic acid) (PLGA) based microparticles (MPs) are widely investigated for their ability to load a range of molecules with high efficiency, including antigenic proteins, and release them in a controlled manner. Micron-sized PLGA MPs are readily phagocytosed by antigen presenting cells, and localized to endosomes. Due to low pH and digestive enzymes, encapsulated protein cargo is largely degraded and processed in endosomes for MHC-II loading and presentation to CD4+ T cells, with very little antigen delivered into the cytosol, limiting MHC-I antigenic loading and presentation to CD8+ T cells...

#17
Tyler M M Stack, Wenzong Li, William H Johnson, Yan Jessie Zhang, Christian P Whitman
5-Halo-2-hydroxy-2,4-pentadienoates (5-halo-HPDs) are reportedly generated in the bacterial catabolism of halogenated aromatic hydrocarbons by the meta-fission pathway. The 5-halo-HPDs, where the halogen can be bromide, chloride, or fluoride, result in the irreversible inactivation of 4-oxalocrotonate tautomerase (4-OT), which precedes the enzyme that generates them. The loss of activity is due to the covalent modification of the nucleophilic amino-terminal proline. Mass spectral and crystallographic analysis of the modified enzymes indicate that inactivation of 4-OT by 5-chloro- and 5-bromo-2-hydroxy-2,4-pentadienoate follows a different mechanism than that for the inactivation of 4-OT by 5-fluoro-2-hydroxy-2,4-pentadienoate...

BACKGROUND: Protein Z (PZ) is a vitamin K-dependent factor that is synthesized mainly by the liver. It acts as an activator of serpin, the protein Z-dependent inhibitor (ZPI), which inhibits factor Xa. The potential role of alterations in protein Z and/or ZPI levels in the pathogenesis of thrombotic and/or hemorrhagic diseases has been previously investigated, but results have been conflicting. The study aim was to evaluate the role of PZ/ZPI polymorphisms in the development of prosthetic valve thrombosis (PVT)...

Zinc and copper are essential metal ions for numerous biological processes. Their levels are tightly maintained in all body organs. Impairment of the Zn2+ to Cu2+ ratio in serum was found to correlate with many disease states, including immunological and inflammatory disorders. Oxytocin (OT) is a neuropeptide, and its activity is modulated by zinc and copper ion binding. Harnessing the intrinsic properties of OT is one of the attractive ways to develop valuable metal ion sensors. Here, we report for the first time an OT-based metal ion sensor prepared by immobilizing the neuropeptide onto a glassy carbon electrode...

In this study, inulin (INU) extracted from burdock root was utilized as a new film base material and combined with chitosan (CHI) to prepare composite films. Oregano and thyme essential oils (OT) were incorporated into the INU-CHI film to confer the films with bioactivities. The physical and optical properties as well as antioxidant and antimicrobial activities of the films were evaluated. INU film alone showed poor physical properties. In contrast, the compatibility of INU and CHI demonstrated by the changes in attenuated total reflectance-Fourier transformation infrared spectrum of the INU-CHI film increased tensile strength and elongation at break of the INU film by 8...
