In nature, metal oxide particles display their existance of picomolecules in solution state at the picoscale and bioactive states in the body. We put evidence of picomolar behavior of picoscale molecules different than nanomolar behavior of particles using PICOTECHNOLOGY devices. PICOTECHNOLOGY means picomolar measurement of picoscale molecule physical properties measured by pico-devices or pic...

This work's goal was to research new candidate antigens for cutaneous leishmaniosis (CL). In order to reach the goal, we used random peptide phage display libraries screened using antibodies from Leishmania braziliensis patients. After selection, three peptides (P1, P2, and P3) were synthesized using Fmoc chemistry. The peptides individually or a mixture of them (MIX) was subsequently emulsifie...

Multiple sclerosis (MS) is a demyelinating autoimmune disease mediated by infiltration of T cells into the central nervous system after compromise of the blood-brain barrier. We have previously shown that administration of tuftsin, a macrophage/microglial activator, dramatically improves the clinical course of experimental autoimmune encephalomyelitis (EAE), a well-established animal model for ...

BACKGROUND There may be an allograft-enhancing effect by the liver on the renal allograft in the setting of simultaneous combined liver-kidney transplantation (CLKT) from the same donor. This study was performed to investigate whether an existing liver allograft could protect a kidney allograft from immunologic injury due to histoincompatibility in liver transplant recipients who received seque...

Emergence of new and medically resistant pathogenic microbes continues to escalate toward worldwide public health, wild habitat, and commercial crop and livestock catastrophes. Attempts at solving this problem with sophisticated modern biotechnologies, such as smart vaccines and microbicidal and microbistatic drugs that precisely target parasitic bacteria, fungi, and protozoa, remain promising ...

Chlamydia trachomatis (CT) is an important cause of sexually transmitted genital tract infections (STIs) and trachoma. Despite major research into chlamydial pathogenesis and host immune responses, immunoprotection has been hampered by the incomplete understanding of protective immunity in the genital tract. Characterized vaccine candidates have shown variable efficacy ranging from no protectio...

BACKGROUND Although uterine macrophages are thought to play an important regulatory role at the maternal-fetal interface, their global gene expression profile is not known. METHODOLOGY/PRINCIPAL FINDINGS Using micro-array comprising approximately 14,000 genes, the gene expression pattern of human first trimester decidual CD14+ monocytes/macrophages was characterized and compared with the expr...

A CpG-containing DNA oligonucleotide functionalized with the 2-(N-formyl-N-methyl)aminoethyl thiophosphate protecting group (CpG ODN fma1555) was prepared from phosphoramidites 1a-d using solid-phase techniques. The oligonucleotide behaved as a prodrug by virtue of its conversion to the well-studied immunomodulatory CpG ODN 1555 through thermolytic cleavage of the 2-(N-formyl-N-methyl)aminoethy...
