N-Arachidonoyldopamine (NADA) was recently identified as an endogenous ligand for the vanilloid type 1 receptor (VR1). Further analysis of the bovine striatal extract from which NADA was isolated indicated the existence of substances corresponding in molecular mass to N-oleoyldopamine (OLDA), N-palmitoyldopamine (PALDA), and N-stearoyldopamine (STEARDA). Quadrupole time-of-flight mass spectrome...

Aflatoxins, the most toxic and carcinogenic family of fungal secondary metabolites, are frequent contaminants of foods intended for human consumption. Previous studies showed that formation of G-group aflatoxins (AFs) from O-methylsterigmatocystin (OMST) by certain Aspergillus species involves oxidation by the cytochrome P450 monooxygenases, OrdA (AflQ) and CypA (AflU). However, some of the ste...

The catecholamines N-acetyldopamine (NADA) and N-b-alanyldopamine (NBAD) are two precursors for quinonoios used as sclerotizing agents in insect cuticle. This study focused on the reaction pathways of the quinones of NADA and NBAD by using two nitrogencentered nucleophiles, imidazole and N-acetylhistidine, to model cuticular proteins containing histidyl residues. The quinones were prepared by e...

In 2013 and 2014, two U.S. universities had meningococcal serogroup B outbreaks (a total of 14 cases) caused by strains from two different clonal complexes. To control the outbreaks, students were immunized with a serogroup B meningococcal vaccine (Novartis) that was not yet licensed in the United States. The vaccine (referred to as MenB-4C) contains four components capable of eliciting bacteri...

Neisseria meningitidis is a human pathogen, which, in spite of antibiotic therapy, is still a major cause of mortality due to sepsis and meningitis. Here we describe NadA, a novel surface antigen of N. meningitidis that is present in 52 out of 53 strains of hypervirulent lineages electrophoretic types (ET) ET37, ET5, and cluster A4. The gene is absent in the hypervirulent lineage III, in N. gon...

The National Acupuncture Detoxification Association (NADA)-standardized 3- to 5-point ear acupuncture protocol, born of a community-minded response to turbulent times not unlike today, has evolved into the most widely implemented acupuncture-assisted protocol, not only for substance abuse, but also for broad behavioral health applications. This evolution happened despite inconsistent research s...

Background: The National Acupuncture Detoxification Association (NADA) protocol, a simple standardized auricular treatment has the potential to provide vast public health relief on issues currently challenging our world. This includes but is not limited to addiction, such as the opioid epidemic, but also encompasses mental health, trauma, PTSD, chronic stress, and the symptoms associated with t...

BACKGROUND Neisseria meningitidis serogroup B has been predominant in Brazil, but no broadly effective vaccine is available to prevent endemic meningococcal disease. To understand genetic diversity among serogroup B strains in Brazil, we selected a nationally representative sample of clinical disease isolates from 2004, and a temporally representative sample for the state of São Paulo (1988-200...

Antigen-specific memory B cells generate anamnestic responses and high affinity antibodies upon re-exposure to pathogens. Attempts to isolate rare antigen-specific memory B cells for in-depth functional analysis at the single-cell level have been hindered by the lack of tools with adequate sensitivity. We applied two independent methods of protein labeling to sensitive and specific ex vivo iden...
