Abstract Chronic stress is among the most costly health problems in terms of direct health costs, absenteeism, disability, and performance standards. The Reformed Church in America (RCA) identified stress among its clergy as a major cause of higher-than-average health claims and implemented HeartMath (HM) to help its participants manage stress and increase physiological resilience. The 6-week HM program...

Abstract This study examined the efficacy of teaching emotional self-regulation techniques supported by heart rhythm coherence training (emWave Personal Stress Reliever) as a means to quickly lower blood pressure (BP) in patients diagnosed with hypertension. Previous studies have demonstrated systemic reductions in BP in both high stress populations and patients diagnosed with hypertension using this approach, but...

The neuroprotective properties of phenotropil and piracetam were studied in Wistar rats with low and high sensitivity with respect to cerebral ischemia caused by bilateral irreversible simultaneous occlusion of carotid arteries and gravitational overload in craniocaudal vector. In addition, the effects of both drugs on microcirculation in the brain cortex under ischemic injury conditions were studied. Phenotropil and (to...

The syndrome in most cases was a progressive state, 15% of patients per year developing dementia, a rate significantly higher than that in the overall population of elderly people.

Proline, cyclo(Pro-Gly), and acyl-prolyl-containing dipeptide GVS-111 decreased synaptoneurosome membrane potential in a Ca2+-free medium. The efficiency of these preparations decreased in the following order: GVS>cyclo(Pro-Gly)>proline. Depolarization responses induced by endogenous nootropic agent cyclo(Pro-Gly) was dose-dependent and saturable; the threshold concentration of cyclo(Pro-Gly) was 10(-9) M. In a Ca2+-containing medium GVS and cyclo(Pro-Gly) induced both hyperpolarizing and depolarizing membrane responses...

Cognition enhancers are drugs able to facilitate attentional abilities and acquisition, storage and retrieval of information, and to attenuate the impairment of cognitive functions associated with head traumas, stroke, age and age-related pathologies. Development of cognition enhancers is still a difficult task because of complexity of the brain functions, poor productivity of animal tests and lengthy and expensive clinical...

Abstract A series of amides and sulfonamides, structurally related to DM235 (sunifiram) and MN19 (sapunifiram), derived by ring expansion or contraction, or by inversion of the exocyclic amide function, have been synthesized and tested for cognition-enhancing activity in the mouse passive-avoidance test. Some of the compounds display good antiamnesic and procognitive activity, with higher potency than piracetam, and with...

Carphedon is a phenyl derivative of nootropil and is effective in increasing physical endurance and cold resistance, and is used for amnesia treatment. Carphedon was extracted from human urine samples by solid-phase microextraction with a 65 microns carbowax-divinylbenzene-coated fiber. This analysis was performed by using capillary gas chromatography with nitrogen-phosphorus detection and optimized at pH 9.6, 30% NaCl, immersion...

Abstract The derivatives of GABA and beta-phenylethylamine (PEA) the tranquilizer phenibut and muscle relaxant baclofen (p-chloro-beta-phenyl-GABA, lioresal) diminished all studied effect of PEA in mice, namely seizures, sedation, excitation, hyperthermia. Diazepam diminished only seizures whereas haloperidol excitation and hyperthermia. PEA injections anatogonized (the sedative and hypothermic effects of phenibut and diazepam and the anticonvulsant (against l-kynurenine) effect of phenibut...

RATIONALE: Acute doses of Ginkgo biloba have been shown to improve attention and memory in young, healthy participants, but there has been a lack of investigation into possible effects on executive function. In addition, only one study has investigated the effects of chronic treatment in young volunteers.
