Neighborhood level air pollution represents a long-standing issue for many communities that, until recently, has been difficult to address due to the cost of equipment and lack of related expertise. Changes in available technology and subsequent increases in community-based participatory research (CBPR) have drastically improved the ability to address this issue. However, much still needs to be learned as these types of studies are expected to increase in the future. To assist, we review the literature in an effort to improve understanding of the motivations, approaches, and outcomes of air monitoring studies that incorporate CBPR and citizen science (CS) principles...

RATIONALE: Production of multiply protonated ions by electrospray ionization (ESI) is important to the analysis of peptides by mass spectrometry. For small neutral and acidic peptides, addition of chromium(III) greatly increases the intensity of doubly protonated ions. The current study examines instrumental and solution parameters that maximize peptide ion charge by ESI. METHODS: The neutral and basic heptapeptides AAAAAAA (A7) and AAAKAAA (A3KA3) were used as test compounds and electrosprayed from a solution containing chromium(III) nitrate at a peptide to metal molar ratio of 1:10...

Using the lanthanide ion praseodymium, Pr(III), metallated ion formation and electron transfer dissociation (ETD) were studied for 25 biological and model acidic peptides. For chain lengths of seven or more residues, even highly acidic peptides that can be difficult to protonate by electrospray ionization will metallate and undergo abundant ETD fragmentation. Peptides composed of predominantly acidic residues form only the deprotonated ion, [M + Pr - H](2+) ; this ion yields near complete ETD sequence coverage for larger peptides...

BACKGROUND: Household air pollution (HAP) from indoor biomass stoves contains harmful pollutants, such as polycyclic aromatic hydrocarbons (PAHs), and is a leading risk factor for global disease burden. We used biomonitoring to assess HAP exposure and association with self-reported symptoms in 334 non-smoking Peruvian women to evaluate the efficacy of a stove intervention program. METHODS: We conducted a cross-sectional study within the framework of a community randomized control trial...

The role of the nurse in improving hypertension control has expanded over the past 50 years, complementing and supplementing that of the physician. Nurses' involvement began with measuring and monitoring blood pressure (BP) and patient education and has expanded to become one of the most effective strategies to improve BP control. Today the roles of nurses and nurse practitioners (NPs) in hypertension management involve all aspects of care, including (1) detection, referral, and follow up; (2) diagnostics and medication management; (3) patient education, counseling, and skill building; (4) coordination of care; (5) clinic or office management; (6) population health management; and (7) performance measurement and quality improvement...

Electrospray ionization (ESI) on mixtures of acidic fibrinopeptide B and two peptide analogs with trivalent lanthanide salts generates [M + Met + H](4+), [M + Met](3+), and [M + Met -H](2+), where M = peptide and Met = metal (except radioactive promethium). These ions undergo extensive and highly efficient electron transfer dissociation (ETD) to form metallated and non-metallated c- and z-ions. All metal adducted product ions contain at least two acidic sites, which suggest attachment of the lanthanide cation at the side chains of one or more acidic residues...

Obesity is a highly prevalent cardiovascular disease risk factor globally and in African-descent populations. A cross-sectional study of obesity among a Nigerian immigrant sample population in the United States was conducted. Data was obtained through a web-based survey. Spearman's correlation and logistic regression were used to determine sociodemographic and behavioral determinants of obesity. The results showed no significant relationship between obesity and education, socioeconomic status, length of stay, and level of physical activity...

While trivalent chromium has been shown at high doses to have pharmacological effects improving insulin resistance in rodent models of insulin resistance, the mechanism of action of chromium at a molecular level is not known. The chromium-binding and transport agent low-molecular-weight chromium-binding substance (LMWCr) has been proposed to be the biologically active form of chromium. LMWCr has recently been shown to be comprised of a heptapeptide of the sequence EEEEDGG. The binding of Cr(3+) to this heptapeptide has been examined...

Sarcoidosis is a chronic systemic disease with a wide array of clinical findings. Given that the clinical symptoms are not pathognomonic, chest radiographs have become essential to the initial diagnosis and choice of treatment modality. Diagnosis hinges on ruling out alternative diagnoses; sometimes, advanced radiologic techniques and histopathology are required. On this occasion, we present a case of a patient with generalized symptoms, no significant chest radiograph findings and lymphadenopathy where advanced imaging and pathology assisted in the diagnosis...

In the 20th century, Africans in Sub-Saharan Africa had lower rates of cardiometabolic disease than Africans who migrated. However, in the 21st century, beyond infectious diseases, the triple epidemics of obesity, diabetes and hypertension have taken hold in Africa. Therefore, Africans are acquiring these chronic diseases at different rates and different intensity prior to migration. To ensure optimal care and health outcomes, the United States practice of grouping all African-descent populations into the "Black/African American" category without regard to country of origin masks socioeconomic and cultural differences and needs re-evaluation...

The development of effective protease therapeutics requires that the proteases be more resistant to naturally occurring inhibitors while maintaining catalytic activity. A key step in developing inhibitor resistance is the identification of key residues in protease-inhibitor interaction. Given that majority of the protease therapeutics currently in use are trypsin-fold, trypsin itself serves as an ideal model for studying protease-inhibitor interaction. To test the importance of several trypsin-inhibitor interactions on the prime-side binding interface, we created four trypsin single variants Y39A, Y39F, K60A, and K60V and report biochemical sensitivity against bovine pancreatic trypsin inhibitor (BPTI) and M84R ecotin...

The addition of chromium(III) nitrate to solutions of peptides with seven or more residues greatly increases the formation of doubly protonated peptides, [M + 2H](2+), by electrospray ionization. The test compound heptaalanine has only one highly basic site (the N-terminal amino group) and undergoes almost exclusive single protonation using standard solvents. When Cr(III) is added to the solution, abundant [M + 2H](2+) forms, which involves protonation of the peptide backbone or the C-terminus. Salts of Al(III), Mn(II), Fe(III), Fe(II), Cu(II), Zn (II), Rh(III), La(III), Ce(IV), and Eu(III) were also studied...

Rapid changes in health care delivery require nurses to attain advanced knowledge, skills, and attitudes in biostatistics to provide high-quality, safe patient care. Advances in educational technologies support the delivery of graduate nursing education in online formats. Given the diversity of learning styles among graduate nursing students and the specific challenges in delivering biostatistics content in traditional formats, it is vital to include different delivery formats to engage and meet the learning needs of graduate nursing students who take biostatistics courses online...

CONTEXT: There is a growing prevalence of cardiovascular disease (CVD) risk factors in West Africa and among its migrants to industrialized countries. Despite this, no study has reviewed CVD risk factor prevalence among West Africans in Africa and industrialized countries. OBJECTIVE: To appraise studies on the prevalence of two CVD risk factors (hypertension and overweight/obesity) among two major West African populations (Ghanaians and Nigerians) in Africa and industrialized countries...

77 K fluorescence spectra of bean (Phaseolus vulgaris cv Commodore) leaves and cotyledons show the presence of active and inactive protochlorophyllides. The first detected product of the protochlorophyllide photoreduction is the chlorophyllide emitting fluorescence at 690 nm (C690) which is observed one day (leaves) and three days (cotyledons) after sowing. In cotyledons, C690 undergoes the 'rapid' and 'Shibata' shifts; in leaves, these spectral changes are age-dependent. In order to characterize the formation of C690, we have recorded 298 K fluorescence kinetics at 690 nm and the corresponding absorbance kinetics at 440 nm...

Nearly half of the world's population is exposed to household air pollution (HAP) due to long hours spent in close proximity to unvented cooking fires. We aimed to use PM2.5 and CO measurements to characterize exposure to cookstove generated woodsmoke in real time among control (n=10) and intervention (n=9) households in San Marcos, Cajamarca Region, Peru. Real time personal particulate matter with an aerodynamic diameter ≤2.5 µm (PM2.5), and personal and kitchen carbon monoxide (CO) samples were taken. Control households used a number of stoves including open fire and chimney stoves while intervention households used study-promoted chimney stoves...

Health behavior theories state that social environments influence health behaviors, but theories of how this occurs are relatively underdeveloped. This article systematically surveys community social capital concepts in health behavior literature and proposes a conceptual framework that integrates these concepts into existing behavioral theory. Fifty-three studies tested associations between community social capital concepts and physical activity (38 studies), smoking (19 studies), and diet (2 studies). Trustworthiness of community members was consistently associated with more health-promoting and less disease-promoting behaviors in 19 studies...

BACKGROUND: Adequate self-care is crucial for blood pressure control. A number of hypertension (HBP) self-care instruments are available, but existing tools do not capture all the critical domains of HBP self-care and have limited evidence of reliability and validity. OBJECTIVE: The purpose of this study was to develop and validate a new tool--the HBP Self-Care Profile (HBP SCP)--in a sample of inner-city residents. METHODS: The HBP SCP encompasses comprehensive domains of HBP self-care behaviors...
