Purpose: It is assumed that case-based questions require higher order cognitive processing, whereas questions that are not case-based require lower order cognitive processing. In this study, we investigated to what extent case-based questions and questions that are not case-based, relate to Bloom's taxonomy.
Methods: In this article, 4800 questions of the Progress Test were classified whether it was a case-based question and the level of Bloom's taxonomy. Read More

Objective: To assess the association between dietary glycemic index (GI) and excess weight in pregnant women in the first trimester of pregnancy.
Methods: A cross-sectional study in a sample of 217 pregnant women was conducted at the maternal-fetal outpatient clinic of the Hospital Geral de Fortaleza, Fortaleza, state of Ceará, Brazil, for routine ultrasound examinations in the period between 11 and 13 weeks + 6 days of gestation. Weight and height were measured and the gestational body mass index (BMI) was calculated. Read More

Objectives: To evaluate the effectiveness of lung cancer screening using low-dose computed tomography for the general population, we conducted a retrospective cohort study of screening for participants among Hitachi residents.
Materials And Methods: Citizens aged 50-74 who underwent low-dose computed tomography screening at least once during 1998-2006 were defined as the computed tomography group, and those who underwent X-ray screening at least once during the same period, but did not receive low-dose computed tomography screening throughout the follow-up period, were defined as the XP group. We investigated the lung cancer incidence rate, mortality rate and all-cause mortality rate for both groups from the first lung cancer screening to the end of 2012. Read More

Background: A diet in which fat is mainly eaten in the morning and carbohydrates mainly in the evening (compared with the reverse order) was recently shown to worsen glycemic control in people with prediabetes.
Objective: We investigated the effects of these dietary patterns on energy metabolism, and on the daily profiles of circulating lipids, adipokines, and inflammatory markers.
Design: In a randomized controlled crossover trial, 29 nonobese men (with normal glucose tolerance, n = 18; or impaired fasting glucose/glucose tolerance, n = 11) underwent 2 isocaloric 4-wk diets: 1) carbohydrate-rich meals until 1330 and fat-rich meals between 1630 and 2200 (HC/HF); or 2) the inverse sequence of meals (HF/HC).

Background: Whole-grain wheat (WGW) is described as nutritionally superior to refined wheat (RW) and thus advocated as the healthy choice, although evidence from intervention studies is often inconsistent. The liver, as the central organ in energy metabolism, might be an important target organ for WGW interventions.
Objective: The aim of this study was to investigate the potential benefits of WGW consumption compared with RW consumption on liver health and associated parameters. Read More

Preclinical noninvasive imaging can be an indispensable tool for studying animal models of disease. In vivo imaging to assess anatomical, functional, and molecular features requires verification by a comparison to the macroscopic and microscopic morphological features, since all noninvasive in vivo imaging methods have much lower resolution than standard histopathology. Comprehensive pathological evaluation of the animal model is underutilized; yet, many institutions have veterinary or human pathologists with necessary comparative pathology expertise. Read More

The role of somatic variants in diseases beyond cancer is increasingly being recognized, with potential roles in autoinflammatory and autoimmune diseases. However, as mutation rates and allele fractions are lower, studies in these diseases are substantially less tolerant of false positives and bio-informatics algorithms require high replication rates. We developed a pipeline combining two variant callers, MuTect2 and VarScan2, with technical filtering and prioritization. Read More

Background/aims: Periosteal tissue is a valuable source of multipotent stem cells for bone tissue engineering. To characterize these cells in detail, we generated an immortalized human cranial periosteal cell line and observed an increased MSCA-1 and CD146 expression, as well as an earlier and stronger mineralization compared to the parental cells. Further, we detected a higher osteogenic potential of MSCA-1high compared to MSCA-1low cranial periosteal cell (CPC) fractions. Read More

The signaling pathways of growth factors including platelet-derived growth factor (PDGF) can be considered specific targets for overcoming the poor prognosis of idiopathic pulmonary fibrosis (IPF). Nintedanib, the recently approved multiple kinase inhibitor, has shown promising anti-fibrotic effects in IPF patients; however, its efficacy is still limited, and in some cases, treatment discontinuation is necessary due to toxicities such as gastrointestinal disorders. Therefore, more effective agents with less toxicity are still needed. Read More

Metatarsalgia can be viewed as more of a symptom rather than a distinct diagnosis. Timing of forefoot pain during the gait cycle and evaluation of whether the pain is from anatomic abnormalities, indirect overloading, or iatrogenic causes can suggest a specific metatarsalgia etiology. A thorough physical examination of the lower extremity, especially evaluation of the plantar foot, and weight-bearing radiographs are critical for diagnosis and treatment. Read More

Aims: Recently, the clinical importance of total antioxidant capacity (TAC) and its protective role against several chronic diseases like cardiovascular disease, osteoporosis and several types of cancers has been reported. However, its association with cardio-metabolic risk factors among patients candidate for coronary artery bypass graft surgery (CABG) has not been evaluated yet. CABG is associated with increased oxidative stress and free radicals; so, the current study was aimed to evaluate the potential association of TAC with cardiovascular risk factors among patients candidate for CABG.

Heterogeneous mobile authentication is a crucial technique to securely retrieve the resource of e-healthcare cloud servers which are commonly implemented in a public key Infrastructure (PKI). Conventionally, a mobile data user can utilize a self-chosen password along with a portable device to request the access privilege of clouds. However, to validate the membership of users, a cloud server usually has to make use of a password table, which not only increases the burden of management, but also raises the possibility of information leakage.

Decomposing vertebrates, including humans, result in pronounced changes in surrounding soil biogeochemistry, particularly nitrogen (N) and carbon (C) availability, and alter soil micro- and macrofauna. However, the impacts of subsurface human decomposition, where oxygen becomes limited and microbial biomass is generally lower, are far less understood. The goals of this study were to evaluate the impact of human decomposition in a multi-individual, shallow (~70 cm depth) grave on soil biogeochemistry and soil microbial and nematode communities.

Background: Exposure to horses can cause severe allergic reactions in sensitized individuals. The breed, American Bashkir Curly Horse is categorized as hypoallergenic, primarily due to reports of allergic patients experiencing fewer symptoms while handling this special breed. The possible reasons for this phenomenon could be lower allergen production and/or reduced allergen release into the air because of increased sebum content in their skin and hair compared to other breeds.

The study of leaf litter as a resource for shredders has emerged as a key topic in trophic links in ecology. However, thus far, most studies have emphasized the leaf quality as one of the main determinants of shredder behaviour and growth without simultaneously considering the leaf quantity availability. Nevertheless, the combined effects of leaf quantity and quality on shredder behaviour and growth is particularly crucial to further understand how ecosystem functioning may respond to the increasing flow intermittency due to climate change.

Hypertensive transgenic (mRen2)27 rats exhibit impaired baroreflex sensitivity (BRS) for control of heart rate (HR). Intracerebroventricular (ICV) infusion of Ang-(1-7) improves indices of vagal BRS independent of lowering mean arterial pressure (MAP), while AT1 receptor blockade normalizes MAP and indices of sympathetic tone without correcting the vagal BRS. Scavenging cellular reactive oxygen species (ROS) with tempol in brain fails to correct either hypertension or sympathovagal balance in these animals, despite reports that mitochondrial ROS contributes to Ang II-infusion hypertension.
