Decreased Expression of Cerebral Dopamine Neurotrophic Factor in Platelets of Probable Alzheimer Patients.

Background: Alzheimer disease (AD) patients experience progressive neurological and cognitive decline attributed to neurodegeneration. Cerebral dopamine neurotrophic factor (CDNF) has been identified to protect and rescue neurons in various preclinical neurodegeneration models. The expression of this protein occurs in both the central nervous system and peripheral blood.

Decreased Expression of Cerebral Dopamine Neurotrophic Factor in Platelets of Stroke Patients.

Background: Cerebral dopamine neurotrophic factor plays a critical role in repairing and maintaining healthy neurons in pathological conditions such as stroke. However, the association between cerebral dopamine neurotrophic factor expression and stroke has only recently been investigated in preclinical models and is rarely described in human studies.

Objectives: The aims of this were to examine neurological alterations mirrored in human blood platelet cerebral dopamine neurotrophic factor gene expression.

Stability, Activity, and Application of Topical Doxycycline Formulations in a Diabetic Wound Case Study.

Introduction: Tetracycline molecules comprise a group of broad-spectrum antibiotics whose primary mechanism of action is the inhibition of protein synthesis through the binding of the bacterial ribosome. In addition, tetracyclines inhibit matrix metalloproteases (MMPs), a family of zinc-dependent proteases that contribute to tissue remodeling, inflammation, and angiogenesis and are overexpressed in certain pathophysiologies such as diabetic foot ulcers (DFUs).

Objective: This study aims to develop a liquid chromatography and mass spectrometry (LC-MS/MS) doxycycline quantification methodology to facilitate the development of a stable topical doxycycline hyclate (DOXY) formulation as well as evaluate the topical DOXY formulation for the efficacy in MMP-9 inhibition in vitro and in a clinical application of diabetic lower extremity wounds.

Penetration and efficacy of transdermal NSAIDs in a model of acute joint inflammation.

Purpose: Prescription and OTC non-steroidal anti-inflammatory drugs (NSAIDs) are ubiquitous treatments for pain and inflammation; however, oral administration of these drugs may produce gastrointestinal (GI) side effects. Transdermal (TD) administration of NSAIDs circumvents these adverse events by avoiding the GI tract and, presumably, achieves regional drug levels of therapeutic effect and thereby, fewer off-target complications.

Methods: A drug quantification method was developed for ibuprofen and celecoxib in canine plasma and synovial fluid using liquid chromatography and mass spectrometry.

A reliable and validated LC-MS/MS method for the simultaneous quantification of 4 cannabinoids in 40 consumer products.

In the past 50 years, Cannabis sativa (C. sativa) has gone from a substance essentially prohibited worldwide to one that is gaining acceptance both culturally and legally in many countries for medicinal and recreational use. As additional jurisdictions legalize Cannabis products and the variety and complexity of these products surpass the classical dried plant material, appropriate methods for measuring the biologically active constituents is paramount to ensure safety and regulatory compliance.

Comparative pharmacokinetics and safety assessment of transdermal berberine and dihydroberberine.

The natural alkaloid berberine has been ascribed numerous health benefits including lipid and cholesterol reduction and improved insulin sensitivity in diabetics. However, oral (PO) administration of berberine is hindered by poor bioavailability and increasing dose often elicits gastro-intestinal side effects. To overcome the caveats associated with oral berberine, we developed transdermal (TD) formulations of berberine (BBR) and the berberine precursor dihydroberberine (DHB).

Implementing Video to Home to Increase Access to Evidence-Based Psychotherapy for Rural Veterans.

This clinical demonstration project used facilitation to implement VA Video to Home (VTH) to deliver evidence-based psychotherapies to underserved rural Veterans, to increase access to mental health care. Participants were Veterans seeking mental health treatment at "Sonny" Montgomery Veterans Affairs Medical Center in Jackson, MS, and/or its six community-based outpatient clinics. Measures included patient encounter and demographic data, patient and provider interviews, reach, effectiveness, adoption, implementation, and maintenance (RE-AIM) factors, measures of fidelity to manualized evidence-based psychotherapies (EBPs), and qualitative interviews.

Racial Differences in the Associations of Posttraumatic Stress and Insomnia With Body Mass Index Among Trauma-Exposed Veterans.

Posttraumatic stress is associated with increased body mass index (BMI) and rates of obesity. Black adults are at greater risk for obesity, trauma exposure, development of posttraumatic stress disorder, and comorbid sleep problems compared to White adults. Accordingly, Black adults with a history of trauma exposure may be at greater risk for elevated BMI associated with posttraumatic stress and insomnia.

A systematic review of behavioral headache interventions with an aerobic exercise component.

Background: Behavioral approaches have been found to be effective in managing chronic headache. Recently, attention has been given to the role of exercise in chronic headache management, although much of the literature addresses it as a monotherapy. The current review assesses the effectiveness of exercise as an adjunct to other behavioral treatments for chronic headache.

Synapsin II gene expression in the dorsolateral prefrontal cortex of brain specimens from patients with schizophrenia and bipolar disorder: effect of lifetime intake of antipsychotic drugs.

Synapsins are neuronal phosphoproteins crucial to regulating the processes required for normal neurotransmitter release. Synapsin II, in particular, has been implied as a candidate gene for schizophrenia. This study investigated synapsin II mRNA expression, using real-time reverse transcriptase-PCR, in coded dorsolateral prefrontal cortical samples provided by the Stanley Foundation Neuropathology Consortium.

Human blood analysis reveals differences in gene expression of catecholamine-regulated protein 40 (CRP40) in schizophrenia.

Heat shock proteins (HSPs) are important players in neurodegeneration and psychiatric disorders. We previously reported significant reductions of a 40-kDa Catecholamine Regulated Protein (CRP40) in schizophrenia post-mortem brain specimens. This study investigated whether gene expression of CRP40 is altered in living subjects with schizophrenia.

Tobacco use and substance use disorders as predictors of postoperative weight loss 2 years after bariatric surgery.

Although evaluations of tobacco and substance use disorders (SUDs) are required before bariatric surgery, the impact of these factors on postsurgical outcomes is unclear. This study describes (1) the prevalence of tobacco and SUDs in 61 veterans undergoing bariatric surgery, (2) associations between presurgical tobacco use and postsurgical weight loss, and (3) relationships between presurgical SUDs and postsurgical weight loss. Height, weight, tobacco, and SUDs were assessed from medical charts at presurgery and 6, 12, and 24 months postsurgery.

Directive support, nondirective support, and health behaviors in a community sample.

Social support is associated with improved psychological functioning, physical health, and health-promoting behaviors. However, research suggests that health outcomes might depend upon the type rather than the amount of support provided to recipients. This study assessed the relationship among nondirective and directive support, and health behaviors (i.

The roles of want to commitment and have to commitment in explaining physical activity behavior.

Background: Several theories and models have been proposed to explain decisions in changing and adopting behavior but few address the intricacies of behavioral maintenance. The current study assesses the utility of the Investment Model, which identifies satisfaction, investments, and involvement alternatives as predictors of commitment and continued behavior, in predicting physical activity behavior.

Methods: Participants (N = 267) completed questionnaires about physical activity and commitment.

Directive and nondirective e-coach support for weight loss in overweight adults.

Background: Although e-coach support increases the effectiveness of Internet weight loss interventions, no studies have assessed influence of type of e-coach support.

Purpose: The effects of nondirective (collaborative, flexible) and directive (prescriptive, protocol driven) e-coach support on weight loss, dietary behavior, physical activity, and engagement were assessed in a 12-week weight loss e-coaching program.

Procedures: Overweight adults (N = 104) were randomly assigned to nondirective, directive, or minimal support.

Personalized feedback to improve CPAP adherence in obstructive sleep apnea.

Obstructive sleep apnea (OSA) is effectively treated with continuous positive airway pressure (CPAP). Low rates of CPAP adherence led to the development of a personalized feedback intervention requiring minimal provider burden. In a comparison of the intervention to standard information, group differences failed to reach significance.

Knockdown of mortalin within the medial prefrontal cortex impairs normal sensorimotor gating.

The 70-kDa mitochondrial heat shock protein, mortalin, is a ubiquitously expressed, multifunctional protein that is capable of binding the neurotransmitter, dopamine, within the brain. Dopamine dysregulation has been implicated in many of the abnormal neurological behaviors. Although studies have indicated that mortalin is differentially regulated in response to dopaminergic modulation, research has yet to elucidate the role of mortalin in the regulation of dopaminergic activity.

The effect of a motivational intervention on weight loss is moderated by level of baseline controlled motivation.

Background: Clinic-based behavioral weight loss programs are effective in producing significant weight loss. A one-size-fits-all approach is often taken with these programs. It may be beneficial to tailor programs based on participants' baseline characteristics.

Antipsychotic drug use is correlated with CRP40/mortalin mRNA expression in the dorsolateral prefrontal cortex of human postmortem brain specimens.

Heat shock proteins act as intracellular chaperones by assisting with proper protein folding in response to various cellular stresses. In doing so, these proteins protect the cell from unwanted protein aggregation, which in turn, plays an important role in the pathogenesis of numerous disorders. Previous reports from our laboratory have described a 40 kDa catecholamine regulated heat shock-like protein (CRP40), an alternate gene product of the 70 kDa mitochondrial heat shock protein, mortalin.

Efficacy of behavioural interventions in managing atypical antipsychotic weight gain.

Atypical antipsychotic treatment is associated with weight gain and increased metabolic risk. This systematic literature review evaluates the current research on the effectiveness of behavioural interventions in treating and preventing atypical antipsychotic weight gain and reducing metabolic risk, describes characteristics of interventions implemented and discusses findings in the context of the RE-AIM framework. Sixteen studies were identified.

Cloning, characterization, and functional studies of a human 40-kDa catecholamine-regulated protein: implications in central nervous system disorders.

Catecholamine-regulated proteins (CRPs) have been shown to bind dopamine and other structurally related catecholamines; in particular, the 40-kDa CRP (CRP40) protein has been previously cloned and functionally characterized. To determine putative human homologs, BLAST analysis using the bovine CRP40 sequence identified a human established sequence tag (EST) with significant homology (accession #BQ224193). Using this EST, we cloned a recombinant human brain CRP40-like protein, which possessed chaperone activity.

Guanosine improves motor behavior, reduces apoptosis, and stimulates neurogenesis in rats with parkinsonism.

Parkinson's disease (PD) is characterized by progressive degeneration of dopaminergic neurons in the substantia nigra pars compacta (SNc) caused by an abnormal rate of apoptosis. Endogenous stem cells in the adult mammalian brain indicate an innate potential for regeneration and possible resource for neuroregeneration in PD. We previously showed that guanosine prevents apoptosis even when administered 48 hr after the toxin 1-methyl-4-phenylpyridinium (MPP(+)).

Differential modulation of a 40 kDa catecholamine regulated protein in the core and shell subcompartments of the nucleus accumbens following chronic quinpirole and haloperidol administration in the rat.

Past reports have shown dopamine (DA) D2/D3 receptor agonist quinpirole (QNP) and the DA D2 receptor antagonist, haloperidol (HAL) display a significant increase in expression of catecholamine regulated protein (CRP40) in the nucleus accumbens (NAcc) and the striatum, respectively. The present study investigated the in vivo effects of QNP and HAL on CRP40 protein levels within the core and shell subcompartments of the NAcc. As significant homology exists between CRP40 and Hsp70/Hsc70, parallel studies with inducible Hsp70 and constitutive Hsc70 were conducted to establish the specificity with respect to QNP on Hsp70 and CRP40.
