It is believed that an effective vaccine against leishmaniasis will require a T helper type 1 (TH 1) immune response. In this study, we investigated the adjuvanticity of the Toll-like receptor (TLR) 7/8 agonist 3M-052 in combination with the Leishmania donovani 36-kDa nucleoside hydrolase recombinant protein antigen (NH36). NH36 and 3M-052 were encapsulated in separate batches of poly(lactic-co-glycolic acid) (PLGA) microparticles (MPs). The loading efficiency for NH36 was 83% and for 3M-052 was above 95%. In vitro stimulation of bone marrow-derived dendritic cells, measured by IL-12 secretion, demonstrated that 3M-052 (free or MP-formulated) had a concentration-dependent immunostimulatory effect with an optimum concentration of 2 µg/mL...

BACKGROUND: In Finland a vaccination programme against human papillomavirus (HPV) was introduced in November 2013 for girls aged 11-12 years with a catchup for girls 13-15 years. Allegations that HPV vaccine is causing Guillain Barré syndrome (GBS) and non-specific diagnostic entities, such as chronic fatigue syndrome/systemic exertion intolerance disease (CFS/SEID) and postural orthostatic tachycardia syndrome (POTS), continue to surface. We examined population register-based incidence rates of CFS/SEID, GBS and POTS to provide baseline data for future HPV vaccine safety evaluations...

Photocatalytically active TiO2-patterned polyimide (PI) films (PI-TiO2) were fabricated using thermal transfer patterning (TTP). When subjected to hot pressing, the TiO2 nanoparticles electrosprayed on steel mesh templates were successfully transferred and formed checker plate patterns on PI film. FE-SEM studies confirmed that pressing at 350°C and 100MPa was optimum for obtaining patterns with uniform TiO2 coverage. When the quantity of TiO2 on the template increased, the amount of it immobilized on PI film also increased from 0...

Our aim was to entrap lactoferrin (LF) in complex nano-particles of whey protein isolate (WPI)-high methoxyl pectin (HMP) with the ratios of 2:1, 1:1, and 1:2 through acidification at pH values of 3, 3.5, and 4. The zeta-potential, size, sedimentable-complex yield, LF content, encapsulation efficiency, SEM, AFM, FTIR, and DSC of nano-particles were investigated. Our results revealed that almost all analyzed parameters of the final nano-particles were related to preparation pH value, WPI/HMP ratios, and acidification methods In both methods of pre- and post-acidification, the zeta potential was decreased via decreasing of pH from 4 to 3 and particle size was increased at higher HMP ratios to WPI...

B-cell superantigens (BC-SAgs) are immunoevasins that have evolved in response to innate catalytic IgM antibodies; germ-line encoded immunoglobulins present in the preimmune repertoire independent of prior antigen exposure. Catalysis is the result of a 2-step process that involves the formation of a non-covalent bond between the BC-SAg and the immunoglobulin first followed by covalent bond formation at the catalytic site resulting in target hydrolysis. Tc24 is a recently described Trypanosoma cruzi BC-SAg hypothesized to play a role in evading the humoral response early in the infection period...

BACKGROUND: The brachioradialis (BR) wrap technique is an option to restore the stability of the distal radioulnar joint (DRUJ). The technique capitalizes on the BR's advantageous insertion point on the radial styloid and the ability of the BR to be harvested with minimal to no deficit. The tendon can then be wrapped around the radius and ulna, tunneling under the pronator quadratus and extensor compartments and secured back into its insertion to provide stability. In this cadaveric study, we used micro-computed tomography (CT) to assess the stability restored by this procedure...

Methylmalonic acid (MMA) accumulates in tissues in methylmalonic acidemia, a heterogeneous group of inherited childhood diseases characterized by neurological dysfunction, oxidative stress and neuroinflammation; it is associated with degeneration of striatal neurons and cerebral cortical atrophy. It is presently unknown, however, whether transient exposure to MMA in the neonatal period is sufficient to trigger inflammatory and apoptotic processes that lead to brain structural damage. Here, newborn mice were given a single intracerebroventricular dose of MMA at 12 hours after birth...
