In studies designed to examine the effects of the immune system, recordings of multi-unit electrical activity (MUA) in the central nervous system were made in the preoptic area/anterior hypothalamus (POA/AH) and paraventricular nucleus (PVN) of rats, following sheep red blood cell (SRBC) immunization. Peak increases in POA/AH MUA were observed on the fifth day following SRBC sensitization, the ...

Heterocyclic amines, suspected as cancer initiators, require metabolic activation to exert genotoxicity. The food carcinogen 2-amino-3-methyl-imidazo[4,5-f]quinoline (IQ) undergoes activation via N-hydroxylation by cytochrome P450 1A2, followed by O-esterification by N-acetyltransferase. We examined the effects of the Ah locus and acetylator polymorphisms (implicated in human colon and bladder ...

Context: Functional implications of clinically relevant abdominal postures have been sparsely examined. Objectives: To evaluate the reliability of sustaining abdominal postures during single-leg landings and the effects of abdominal postures on lower extremity kinetics and energetics. Design: One-way ANOVA tested effects of leg-spring stiffness and lower extremity energetics across groups (cont...

In hamsters, adolescent anabolic-androgenic steroid (AAS) exposure facilitates offensive aggression, in part by altering the development and activity of anterior hypothalamic arginine vasopressin (AH-AVP). This study assessed whether these effects were lasting by examining aggression and AH-AVP during AAS withdrawal. Adolescent hamsters administered AAS were tested as adults for aggression at 1...

We refer to the real Jordan Banach algebra of bounded Hermitian operators on a Hilbert space as a Hermitian algebra. We define an abstract Hermitian algebra (AH-algebra) to be the directed group of an e-ring that contains a semitransparent element, has the quadratic annihilation property, and satisfies a Vigier condition on pairwise commuting ascending sequences. All of this terminology is expl...

The Mayo and Flory mechanisms for the self-initiation of styrene polymerization were explored with B3LYP and BPW91 density functional calculations. The Diels-Alder dimer (AH) is the key intermediate, and the lowest energy pathway for AH formation is a stepwise mechanism via a gauche/sickle (*M2*Gs) or gauche/U-shaped (*M2*Gu) diradical. Ring closure of the 1,4-diradical to diphenylcyclobutane (...

Purpose To study the ciliary neurotrophic factor (CNTF) concentration in the aqueous humor (AH), lacrimal fluid (LF), and blood serum (BS) in patients with age-related cataract and primary open-angle glaucoma (POAG). Methods CNTF concentrations were studied in 61 patients with age-related cataract, 55 patients with POAG combined with cataract, and 29 healthy controls (one eye in each person)....

Activation heat (AH) is an important component in energy balance of muscle contraction. It represents energy dissipation of biochemical processes enabling muscle in rest to perform contraction. According to our measurements on intact muscles, AH is 20% of initial heat production in twitch, and 10% in tetanus. Significantly different AH values have been obtained for muscles of parallel and not p...
