A conserved genetic toolkit underlies the development of diverse floral forms among angiosperms. However, the degree of conservation vs divergence in the configuration of these gene regulatory networks is less clear. We addressed this question in a parallel genetic study between the closely related species Arabidopsis thaliana and Cardamine hirsuta. We identified leafy (lfy) and apetala1 (ap1) alleles in a mutant screen for floral regulators in C. hirsuta. C. hirsuta lfy mutants showed a complete homeotic conversion of flowers to leafy shoots, mimicking lfy ap1 double mutants in A...

STUDY DESIGN: Longitudinal twin-cohort study. OBJECTIVE: To investigate the impact familial aggregation of chronic low back pain (LBP) has on the recovery from chronic LBP. SUMMARY OF BACKGROUND DATA: LBP is a worldwide problem, with pain and disability often becoming chronic. Genetics and familial behaviours could significantly impact the recovery from chronic LBP but have not been extensively investigated. METHODS: 624 Spanish twins from the Murcia Twin Registry reported experiencing chronic LBP within the past two years during the 2009/11 data collection wave and were followed up in 2013...

BACKGROUND: Developmental dysplasia of the hip is effectively treated with a Pavlik harness (PH) within the first 6 months of life. Over 80% of unstable hips in the newborn period will naturally stabilize by 2 months of age. If there is no difference in the effectiveness of initiating PH treatment at 1 week compared with 4 weeks of age, waiting may allow the hips to naturally stabilize and avoid treatment. The purpose of this study is to evaluate whether the timing of PH implementation influences its effectiveness in the treatment of developmental dysplasia of the hip...

S Kaviani, J A Cooper
Dietary fatty acids (FA) act as signaling molecules with diverse effects on physiologic function. The aim of this article is to review and summarize the clinical human studies in the literature on how dietary FA composition in meals and diets affects hunger and satiety signaling in the body. Studies examining FA saturation (monounsaturated (MUFA), saturated or polyunsaturated (PUFA) FAs) or FA chain length from high-fat meals/diets were included. Measures of appetite included visual analog scale (VAS) questionnaires, appetite hormones (Cholecystokinin (CCK), glucagon-like peptide-1 (GLP-1), peptide YY (PYY), gastric insulinotropic polypeptide gastric inhibitory peptide (GIP), ghrelin, leptin, insulin) and/or energy intake (EI) data...

More than thirty years have passed since the beginning of the psychiatric reform, a period of intense and relevant social, scientific and cultural changes which have directly impacted on mental disorders and their management. Improvement in psychopharmacological treatment, a new model of physician-patient relationship, patient´s empowerment as a key issue and the fight against social stigma related to mental health disorders, changes in clinical governance and health policy, the assistential burden derived from the treatment of less severe pathology in mental health community centers, improvements in teamwork and coordination with other resources involved… are some of the relevant changes which determine the scene of community-based mental health assistance...

BACKGROUND: Hyponatremia and delirium are frequent problems in older hospitalized patients. Although confusional states are considered to be a possible complication of hyponatremia, there has been no systematic study to date of the precise prevalence of delirium among patients with hyponatremia and its effect on long-term outcomes. METHODS: In a 13-month period in 2009/2010, all patients with a serum sodium level less than or equal to 130 mmol/L (the hyponatremia group) in a cohort of hospitalized older patients were studied and compared to a normonatremic control group of patients who were matched for age, sex, and diagnosis group...

BACKGROUND: Electronic cigarettes (e-cigarettes) are a consumer product whose benefits and risks are currently debated. Advocates of the "tobacco harm reduction" strategy emphasize their potential as an aid to smoking cessation, while advocates of the precautionary principle emphasize their risks instead. There have been only a few studies to date on the prevalence of e-cigarette use in Germany. METHODS: In May 2016, in collaboration with Forsa, an opinion research firm, we carried out a survey among 4002 randomly chosen persons aged 14 and older, asking them about their consumption of e-cigarettes with and without nicotine, reasons for using e-cigarettes, plans for future use, estimation of danger compared to that of tobacco products, smoking behavior, and sociodemographic features...

INTRODUCTION: The terminal ileum is the most involved tract in Crohn's disease. The obstruction in this location is the most frequent complication. Acute or chronic presentations can occur. Surgery finds a role in the management of chronic strictures and in acute clinical presentations with complications not improving with conservative therapy. PATIENTS AND METHODS: We investigate the outcome of patients with obstruction of the ileo-cecal bowel tract laparoscopically managed...

The positive relationship between plant diversity and ecosystem functioning has been criticized for its applicability at large scales and in less controlled environments that are relevant to land management. To inform this gap between ecological theory and application, we compared recovery rates of belowground properties using two chronosequences consisting of continuously cultivated and independently restored fields with contrasting diversity management strategies: grasslands restored with high plant richness and managed for diversity with frequent burning (n=20) and grasslands restored with fewer species that were infrequently burned (n=15)...

Pangolins are ant specialists which are under intense threat from the illegal wildlife trade. Nutrition has notoriously been their downfall in captivity and is still an issue in regards to rescue and rehabilitation. We analyzed the nutrient content of diets used by institutions that are successfully keeping Asian pangolins and to assess the variety of the ingredients and nutrients, compared these with the nutritional requirements of potential nutritional model species. We performed intake studies at five institutions and also had data from three other institutions...

PURPOSE: In the design of nuclear medicine treatment and examination rooms, an important consideration is the shielding required for ionizing radiation from the radioactive isotopes used. The shielding in the walls is normally limited to a height lower than the actual ceiling height. The direct radiation, possibly with build-up correction, can be calculated relatively easily. However, little data is available to estimate the dose contribution from ionizing radiation traveling over the wall shielding and scattering off the ceiling...

HIV prevention programs often focus on the physical social venues where men who have sex with men (MSM) frequent as sites where sex behaviors are assumed to be practiced and risk is conferred. But, how exactly these behaviors influence venue patronage is not well understood. In this study, we present a two-mode network analysis that determines the extent that three types of sex behaviors-condomless sex, sex-drug use, and group sex-influence the patronage of different types of social venues among a population sample of young Black MSM (YBMSM) (N = 623)...

The molecular processes that establish fear memory are complex and involve a combination of genetic and epigenetic influences. Dysregulation of these processes can manifest in humans as a range of fear-related anxiety disorders like post-traumatic stress disorders (PTSD). In the present study, immunohistochemistry for acetyl H3, H4, c-fos, CBP (CREB-binding protein) in the infralimbic prefrontal cortex (IL-PFC) and prelimbic prefrontal cortex (PL-PFC) of mPFC (medial prefrontal cortex) and basal amygdala (BA), lateral amygdala (LA), centrolateral amygdala (CeL), centromedial amygdala (CeM) of the amygdala was performed to link region-specific histone acetylation to fear and extinction learning...

Evidence from general population studies shows the contribution of various temperament traits to the development of child psychopathology. Little is known about which traits are associated with internalizing and externalizing problems in young clinically referred children. The current study assessed temperament and internalizing and externalizing problems in 216 referred children (M = 4.35 years, SD 0.89, 81% boys). A comparison was made with an age and gender matched general population sample. Referred children showed less effortful control than general population children...

BACKGROUND: The validity of indirect bypass for adult patients with moyamoya disease is still debatable. Some patients are poor responders to indirect bypass, and additive intervention is occasionally required in these cases. Therefore, it is necessary to evaluate the development of collateral circulation as early as possible postoperatively. METHODS: Fifteen adult patients (>17 years old) with moyamoya disease (22 affected sides) who underwent encephalo-duro-arterio-synangiosis (EDAS) at Fukuoka University Hospital from April 2008 to August 2014 were included...

REVIEW
Alexander Widiapradja, Prasad Chunduri, Scott P Levick
In addition to traditional neurotransmitters of the sympathetic and parasympathetic nervous systems, the heart also contains numerous neuropeptides. These neuropeptides not only modulate the effects of neurotransmitters, but also have independent effects on cardiac function. While in most cases the physiological actions of these neuropeptides are well defined, their contributions to cardiac pathology are less appreciated. Some neuropeptides are cardioprotective, some promote adverse cardiac remodeling and heart failure, and in the case of others their functions are unclear...

Importance: Renal transplantation is associated with reduction in the risk for myocardial infarction (MI) in patients with chronic kidney disease requiring long-term dialysis (stage 5D CKD). Whether outcomes of MI differ among renal transplant recipients vs patients with stage 5D CKD or those without CKD has not been well examined. Objectives: To compare in-hospital reperfusion rates and outcomes of ST-segment elevation MI (STEMI) in renal transplant recipients vs the stage 5D CKD group or the non-CKD group...

Importance: Colonic stenting was introduced for palliation of malignant large-bowel obstruction (MLBO) more than 20 years ago but remains controversial. Objective: To compare outcomes after palliative stenting vs stoma creation in patients with MLBO requiring emergency management. Design, Setting, and Participants: This observational cohort study assessed 345 patients from New York State with an urgent or emergency admission to the hospital for obstruction secondary to colorectal cancer and who underwent stenting or stoma creation from October 1, 2009, through December 31, 2013...

PURPOSE: Rigid and flexible cystoscopies are both routinely used in female patients. Literature is conflicting whether flexible cystoscopy is less painful compared to rigid cystoscopy. The aim of this study was therefore to investigate whether using flexible cystoscopy leads to less discomfort and pain compared to rigid cystoscopy in female patients who underwent first time cystoscopy. MATERIALS AND METHODS: One hundred eighty-nine female patients, who never had undergone cystoscopy, were randomized into 2 groups: 92 patients underwent rigid cystoscopy and 97 patients flexible cystoscopy...

BACKGROUND: Results from a previous multicenter randomized controlled trial (RCT) on preoperative pain neuroscience education (PNE) for lumbar radiculopathy found no significant difference in patient reported outcomes between groups. However, patients who received PNE viewed their surgical experience more favorably and utilized significantly less healthcare compared to those that did not. The purpose is to determine if the reduction in healthcare costs from 1-year would be continued at 3-year following surgery, and to explore differences (if any) in patient reported outcomes...
