STUDY DESIGN: A radiographic evaluation of standing cervical and global sagittal alignment in 100 adult volunteers with no neck or radicular arm symptoms was undertaken. OBJECTIVES: To document and define cervical standing lateral alignment and balance in a volunteer population without cervical problems. SUMMARY OF BACKGROUND DATA: Minimal data exist on cervical segmental sagittal alignment distributions in stance. METHODS: Radiographic measures of spinal alignment were collected and statistically analyzed. RESULTS: Data were categorized into two age- and sex-matched groups. Group 1 had no cervical or lumbar symptoms. Group 2 had no cervical symptoms, but had lumbar symptoms. Mean total and segmental cervical alignment distributions were not statistically different between groups. Mean total cervical lordosis in stance for the entire group was -40.0 +/- 9.7 degrees. Thoracic and lumbar alignment were within previously reported measures and not statistically different between groups. Plumb line markers at C7 and sacral reference points were not statistically different between groups. Pearson correlations revealed that cervical sagittal plane alignment vaired inversely with thoracic alignment. Independent orthopedists noted cervical osteoarthritis was present in 17% of each group of volunteers with substantial kappa agreement (0.73) between observers. Intraobserver and interobserver reliability of sagittal alignment measures of 30 randomly remeasured radiographs revealed strong correlation between observations. CONCLUSIONS: No differences in total cervical lordosis were noted between cervical asymptomatic volunteers with or without low back pain. Most cervical lordosis occurred at the C1-C2 level in stance, whereas only 6 degrees (15%) occurred at the lowest three cervical levels (C4-C7). Changes in cervical lordosis correlated inversely with changes in thoracic alignment.

During pregnancy, untreated sexually transmitted or urinary tract infections are associated with significant morbidity, including low birth weight, preterm birth, and spontaneous abortion. Approximately one in four women will be prescribed an antibiotic during pregnancy, accounting for nearly 80% of prescription medications in pregnant women. Antibiotic exposures during pregnancy have been associated with both short-term (e.g., congenital abnormalities) and long-term effects (e.g., changes in gut microbiome, asthma, atopic dermatitis) in the newborn. However, it is estimated that only 10% of medications have sufficient data related to safe and effective use in pregnancy. Antibiotics such as beta-lactams, vancomycin, nitrofurantoin, metronidazole, clindamycin, and fosfomycin are generally considered safe and effective in pregnancy. Fluoroquinolones and tetracyclines are generally avoided in pregnancy. Physiologic changes in pregnancy lead to an increase in glomerular filtration rate, increase in total body volume, and enhanced cardiac output. These changes may lead to pharmacokinetic alterations in antibiotics that require dose adjustment or careful monitoring and assessment.

Macrophages have been identified in mouse kidney by immunohistochemical localization of the macrophage-specific antigen F4/80. They constitute the majority of the renal medullary interstitial cell population and are also found in contact with cortical distal and proximal tubules and Bowman's capsule. They are a physical component of the juxtaglomerular complex.

One hundred twenty-nine undergraduate students were assessed for suicidal preoccupation, using the Alabama Adolescent Health Survey (AAHS) and selected cards from the Thematic Apperception Test (TAT). They were also administered the Multidimensional Perfectionism Scale (MPS) to assess perfectionistic tendencies. Objective scoring of the TAT was found to be highly reliable. Canonical correlational analyses were nonsignificant for a relationship between perfectionism and suicidal themes on the TAT. However, the more direct questions of the AAHS relating to suicide were significantly related to perfectionism. Results suggest that passive perfectionists who procrastinate out of fear of making mistakes are more likely to be preoccupied with suicide, unlike perfectionists whose strivings produce achievement. High personal standards and parental expectations do not appear related to suicidal preoccupations.

The purpose of this study was to identify student characteristics that might influence teachers in referring students for gifted programs. We developed a series of 12 student profiles to measure teacher bias and asked teachers to indicate how strongly they believed the students in the profiles should or should not be recommended for their district gifted program. We found the ability to do mental computations overshadowed completion of schoolwork, and the esoteric nature of student interest appeared to be equivalent to completion of schoolwork. We found that completing schoolwork was not a factor when students possessed a large storehouse of information. We also learned that classroom teachers may be more inclined than gifted specialists to focus on student weaknesses, rather than student strengths.

This article is an examination of the theoretical views of perfectionism, some of the instruments available to measure the construct, and the empirical evidence related to perfectionism in both the general and gifted populations. Areas of needed research are addressed. Particular emphasis is given to the multidimensional nature of the construct of perfectionism.

This study used a holistic wellness paradigm to explore the adjustment of student‐athletes and nonathletes at a Division I institution. Results were that nonathletes reported higher levels of wellness than did student‐athletes. The authors discuss the ways in which wellness may affect student‐athletes' physical and mental health at different points in time during their collegiate experience. Implications for college counselors and other student affairs professionals who support student‐athletes are presented.

In the last two decades there have been dramatic changes in the epidemiology of Clostridium difficile infection (CDI), with increases in incidence and severity of disease in many countries worldwide. The incidence of CDI has also increased in surgical patients. Optimization of management of C difficile, has therefore become increasingly urgent. An international multidisciplinary panel of experts prepared evidenced-based World Society of Emergency Surgery (WSES) guidelines for management of CDI in surgical patients.

can also be used to successfully map AChE activity in different regions of a normal mouse brain, which may provide important data for AChE evaluation in clinical studies. Such a rational and effective approach can also provide a solid basis for designing probes with different properties to study AChE in biosystems and another way to design specific substrates for other enzymes.

Citrulline-malate (CM) has been proposed to provide an ergogenic effect during resistance exercise; however, there is a paucity of research investigating these claims. Therefore, we investigated the impact that CM supplementation would have on repeated bouts of resistance exercise. Fourteen resistance-trained males participated in a randomized, counterbalanced, double-blind study. Subjects were randomly assigned to placebo (PL) or CM (8 g) and performed three sets each of chin-ups, reverse chin-ups, and push-ups to failure. One week later, subjects ingested the other supplement and performed the same protocol. Blood lactate (BLa), heart rate (HR), and blood pressure (BP) were measured preexercise, with BLa measured a second time immediately following the last set, while HR and BP were measured 5 and 10 min postexercise. Citrulline-malate ingestion significantly increased the amount of repetitions performed for each exercise (chin-ups: PL = 28.4 ± 7.1, CM = 32.2 ± 5.6, p = .003; reverse chin-ups: PL = 26.6 ± 5.6, CM = 32.1 ± 7.1, p = .017; push-ups: PL = 89.1 ± 37.4, CM = 97.7 ± 36.1, p < .001). Blood lactate data indicated a time effect (p < .001), but no treatment differences (p = .935). Systolic BP data did not show differences for time (p = .078) or treatment (p = .119). Diastolic BP data did not show differences for time (p = .069), but indicated treatment differences (p = .014) for subjects ingesting CM. Collectively, these findings suggests that CM increased upper-body resistance performance in trained college-age males.

Instructors often use Microsoft PowerPoint lectures and handouts as support tools to provide students with the main concepts of the lectures. Some instructors and researchers believe that PowerPoint encourages student passivity. We conducted 2 studies to determine whether the use of content-based questions (CBQs) would enhance learning when combined with traditional PowerPoint lectures. Our results indicated significantly higher quiz scores and exam scores when students used CBQs in comparison to using only the traditional PowerPoint lecture and handouts. The results suggest that it is possible to incorporate effective active learning methods into PowerPoint-based lectures.

Purpose The purpose of this paper is to identify the factors affecting user acceptance for NFC mobile wallets in both Korean and US markets. Design/methodology/approach The proposed model extends the UTAUT2 model with new constructs of credibility (CR) and service smartness (SS). This study was analyzed using partial least square structural equation modeling on data collected from 701 college students between the ages of 18 and 29. Findings The results of this study demonstrate that performance expectancy (PE), effort expectancy (EE), CR, SS and habit (HB) have strong positive relationships with a user’s behavioral intention to use NFC mobile wallets. Comparing the results of the USA and South Korea, there are different results regarding PE and CR. Research limitations/implications This study shows that all factors except social influence (SI) have significant positive relationships with the intention to adopt NFC mobile wallets: Among the original UTUAT2 factors, PE, EE and HB are important determinants of NFC mobile wallet adoption and the new constructs, CR and SS, are significant determinants that influence BI. However, the target respondents are limited to college students of South Korea and the USA Thus, caution should be used when applying the results of this study towards less ICT developed countries and towards different age groups. Practical implications This study provides multiple practical contributions. First, this study emphasizes HB as the strongest factor for adopting NFC mobile wallets in both South Korea and the USA Second, this study also highlights the importance of SS. Third, this study reveals that SI is not associated with the adoption of NFC mobile wallets. Fourth, nationality differences between the USA and South Korea account for the differences in consumer behaviors. Originality/value This study has two main contributions: First, this study introduces a modified UTAUT2 model with two new variables (CR and SS) useful for NFC mobile wallets. Second, this study compares the results of partial least square structured equation models (PLS-SEM) of the two nationality groups, South Korea and the USA

BACKGROUND: Chiropractors claim to locate, analyze and diagnose a putative spinal lesion known as subluxation and apply the mode of spinal manipulation (adjustment) for the correction of this lesion. AIM: The purpose of this examination is to review the current evidence on the epidemiology of the subluxation construct and to evaluate the subluxation by applying epidemiologic criteria for it's significance as a causal factor. METHODS: The databases of PubMed, Cinahl, and Mantis were searched for studies using the keywords subluxation, epidemiology, manipulation, dose-response, temporality, odds ratio, relative risk, biological plausibility, coherence, and analogy. RESULTS: The criteria for causation in epidemiology are strength (strength of association), consistency, specificity, temporality (temporal sequence), dose response, experimental evidence, biological plausibility, coherence, and analogy. Applied to the subluxation all of these criteria remain for the most part unfulfilled. CONCLUSION: There is a significant lack of evidence to fulfill the basic criteria of causation. This lack of crucial supportive epidemiologic evidence prohibits the accurate promulgation of the chiropractic subluxation.

A review of the literature reveals that although the teaching of critical thinking skills is a significant aim of post-secondary pedagogy, much ambiguity exists regarding the topic. In fact, due to the lack of faculty familiarity with the concept compounded by student resistance to put forth the intellectual labor to take charge of their own thinking, matriculates are mainly exposed to didactic instruction that does not prepare them with real-world problem solving skills. This manuscript addresses these problems in the following way. First, it outlines a foundational conception of critical thinking as articulated by the Foundation for Critical Thinking. In doing so, it comments on the importance of student-centered instruction as key to fostering critical thinking skills and dispositions in the classroom. Second, it canvasses an example of what critical thinking instruction and learning can look like.

Organ-specific cell-penetrating peptides (CPPs) are a class of molecules that can be highly effective at delivering therapeutic cargoes, and they are currently of great interest in cancer treatment strategies. Herein, we describe a new CPP (amino acid sequence serine-isoleucine-tyrosine-valine, or SIWV) that homes to glioblastoma multiforme (GBM) brain tumor tissues with remarkable specificity in vitro and in vivo. The SIWV sequence was identified from an isoform of annexin-A3 (AA3H), a membrane-interacting human protein. The mechanism of intracellular permeation is proposed to follow a caveolin-mediated endocytotic pathway, based on in vitro and in vivo receptor inhibition and genetic knockdown studies. Feasibility as a targeting agent for therapeutics is demonstrated in a GBM xenograft mouse model, where porous silicon nanoparticles (pSiNPs) containing the clinically relevant anticancer drug SN-38 are grafted with SIWV via a poly-(ethylene glycol) (PEG) linker. The formulation shows enhanced in vivo targeting ability relative to a formulation employing a scrambled control peptide, and significant (P < 0.05) therapeutic efficacy relative to free SN-38 in the GBM xenograft animal model.

PURPOSE: This study assessed African American adolescents' receptivity to an HIV-prevention curriculum enhanced by text messaging. DESIGN AND METHODS: Two focus groups were conducted with 14 African American adolescents regarding how an HIV-prevention curriculum could be enhanced for text messaging delivery. RESULTS: The adolescents were receptive to the idea of text messaging HIV-prevention information but wanted to receive a maximum of three messages per day during the hours of 4:00-6:00 p.m. PRACTICE IMPLICATIONS: By taking the findings of this study, nurses, other healthcare providers, and community-based organizations can adapt evidence-based interventions for text messaging delivery to individuals at high risk for HIV infection.

Two of the most critical factors for the survival of glioblastoma (GBM) patients are precision diagnosis and the tracking of treatment progress. At the moment, various sophisticated and specific diagnostic procedures are being used, but there are relatively few simple diagnosis methods. This work introduces a sensing probe based on a turn-on type fluorescence response that can measure the cysteine (Cys) level, which is recognized as a new biomarker of GBM, in human-derived cells and within on-site human clinical biopsy samples. The Cys-initiated chemical reactions of the probe cause a significant fluorescence response with high selectivity, high sensitivity, a fast response time, and a two-photon excitable excitation pathway, which allows the imaging of GBM in both mouse models and human tissue samples. The probe can distinguish the GBM cells and disease sites in clinical samples from individual patients. Besides, the probe has no short or long-term toxicity and immune response. The present findings hold promise for application of the probe to a relatively simple and straightforward following of GBM at clinical sites.

In this study, a series of simultaneous multiple regression analyses were conducted to examine the relationship between racial identity development and college adjustment for a sample of 76 Choctaw community college students in the South. Results indicated that 3 of the 4 racial identity statuses (dissonance, immersion‐emersion, and internalization) were significantly related to college adjustment, whereas the 4th status, conformity, was not. Implications for research and practice are provided.

This study examined trends and patterns in public school teacher convictions in order to create a descriptive profile of teachers who have offended against their students. To accomplish this goal, the authors reviewed public records for demographic information as well as the history and frequency of teacher arrests and convictions in the southeastern United States from 2007 to 2011 and created an offender profile. Subsequent analyses were conducted to assess whether gender differences among sexual misconduct offenders existed in terms of the age of their alleged victim, the grade level in which they were employed at the time of arrest or indictment, and the manner by which their alleged crimes were revealed and charges were brought against them.

Purpose The purpose of this study was to characterise the physiochemical properties of selected exotic seasonal tropical fruits available in Singapore. Design/methodology/approach A total of 11 seasonal tropical fruits including cempedak, chiku, custard apple, jackfruit, longkong, mangosteen, red jambu, pearl jambu, rambutan, salak and starfruit were analyzed for their sugars, organic acids and free phenolic acids composition using liquid chromatographic methods. Total phenolic content (free and bound), total soluble solids and pH were determined using Folin‐Ciocalteu method, refractometer and pH meter, respectively. Findings Fructose, glucose and sucrose were the main sugars in all the fruits. Cempedak had the highest sucrose concentration, while custard apple had the highest content of fructose and glucose. Malic and citric acids were the major organic acids in most of the fruits, except for pearl jambu and red jambu where succinic acid was the dominant acid. The total phenolic content varied from 122.94 to 712.20 mg gallic acid equivalent (GAE)/kg fresh weight (FW). Ferulic (0.631 mg/kg) and sinapic acids (1.506 mg/kg) were the predominant free phenolic acids in custard apple, while caffeic acid was the main free phenolic acid in jackfruit, salak and starfruit. Originality/value The paper demonstrates that the physiochemical characteristics of the 11 tropical fruits varied markedly, which is responsible for the differential flavour and stability. The findings are useful for epidemiological research and predicting the degree of ripeness, stability and post‐harvest processing required for these fruits.
