To establish a stable in vivo gastrointestinal model of WZS mini-pig to evaluate the digestibility of rice genetically modified with CpTI (Cowpea Trypsin Inhibitor). METHODS; Three WZS mini-pigs were surgically fitted with O-stomach cannula and T-ileum cannula, and fed with soybean (positive control), CpTI rice and its parental rice meals. The pH value of gastric and intestinal fluid was monitored at different time points. The digested protein products were measured with protein gel electrophoresis at different time points. The pH value of gastric contents was rapidly neutralized by the meal to approximately 6.0, then the pH was reduced by HCl secretion,and it subsequently was increased after 4-6 hours. Compared with rice,the increase or decrease of pH after soybean being fed was later. Soybean protein segments 13kD,17kD, 34kD and 50kD could be highly detected in gastric and intestinal fluid at 5-6h after soybean being introduced. The segment 13kD was digested in intestine. However, no any protein segment was found in the gastric fluid 0.25h after rice being fed. There was no any difference in digestibility between the rice genetically modified with CpTI and its parental rice. It is practicable to establish a in vivo model of WZS mini-pig for digestibility. The digestibility of CpTI rice and its parental rice in gastric and intestinal tract in vivo is equivalent.

Intrauterine inoculation of minipigs with Chlamydia trachomatis during diestrus establishes a longer lasting infection compared to vaginal inoculation during estrus

Advanced animal models, such as minipigs, are needed for the development of a globally requested human Chlamydia vaccine. Previous studies have shown that vaginal inoculation of sexually mature Göttingen minipigs with Chlamydia trachomatis resulted in an infection lasting only 3-5 days. The aim...... resulted in a longer lasting infection (at least 10 days) compared to estrus (3-5 days). Furthermore, we found a significant C. trachomatis specific IFN-γ response in pigs inoculated during estrus correlating with the accelerated clearance of infection in these pigs. These findings suggest...

Potential and limits of mammography (Statistical and casuistic investigation of clinically positive, mammographically negative cases among the patients of Goettingen Radiological University Hospital)

Energy Technology Data Exchange (ETDEWEB)

Pforte, A.

1978-01-01

In the radiological clinic of the Goettingen University, 23,945 patients were mammographed from 1971 to 1977. For 612 patients with existing clinical findings, a negative radiological finding was established; as for the 202 patients who are dealt with in this paper, in 192 of these cases a histological or cytological clarification was carried out; 10 other cases were observed over a longer period. The average age of the patients examined was 39.7 years. The maximum frequency with regard to the age lies in the 5th life decade with 26.2%. Corresponding to the Goettingen model, the patients examined were assigned to 4 main groups in accordance to their parenchymal structure. In relation to the mamma structure, the clinical finding in 53.9% is hardening and in 46.1% nodes. As for the nodes, most have the size of cherry or plum (21.3%), this is followed by those with the size of beans (13,8%) and lenses (10.9%). A coherence between age and size of the clinical finding cannot be manifested definitely. In nearly half of the cases, the histological or cytological examination revealed a mastopathy (48.9%). In 10.4% a fibroadenoma was found and in 2.1% a carcinoma. In the remaining 32,8% the finding referred to lipomas, mastitis, atypical cells or negative cytological results. Related to the age, mastopathy is dominant in women between 20 and 60 years of age. In women below 20 years, fibroadenomas are dominant, in women in their 7th decade other benign diagnoses which in the 8th decade are of the same frequency as carcinomas. With increasing age, the number of fibroadenomas decreases.

Object recognition as a measure of memory in 1–2 years old transgenic minipigs carrying the APPsw mutation for Alzheimer’s disease

2012-01-01

Alzheimer’s disease (AD) is a disabling, fatal disease, where animal models potentially can enable investigation of aetiology and treatment. The first litter of Göttingen minipigs carrying a mutation for human AD was born in 2007, showing transgene expression. In human AD patients, memory...... impairment is the most striking and consistent feature. The aim of the present study was to examine effects of the APPsw transgene on memory of AD minipigs compared with non-transgenic controls at two ages (1–2 years) using the spontaneous object recognition test (SORT), which is based on behavioural...... using the SORT, we were not able to show memory impairment in APPsw carrying minipigs. Being an age-dependent disease, the transgene is expected to cause AD-like symptoms in this porcine model, and the SORT should be repeated at older ages...

Medical schools in Germany may select 60% of the student applicants through their own admission tests. The influence of the school-leaving examination grades (EGs) in each of the procedural steps is controversial. At Goettingen Medical School, we combine a structured interview and a communicative skills assessment. We analysed how many applicants succeeded in our admission test, compared to a model which only takes EGs into account. Admission scores were transferred into SPSS-21. Sociodemographic data were submitted by the Stiftung Hochschulstart. Besides descriptive statistics, we used Pearson-correlation and means comparisons (t-test, analysis of variance). 221 applicants (EGs 1.0-1.9) were invited in the winter semester 2013/14 and 222 applicants (EGs 1.1-1.8) in the summer semester 2014. The proportion of women was 68% (winter) and 74% (summer). Sixteen and 37 applicants had a medical vocational training and performed slightly better. The analysis showed that our test was gender neutral. EGs did not correlate with interviews or skills assessment. Despite a two-fold impact of EGs, 26 (winter) and 44 (summer) of the overall 181 applicants had EGs of 1.4 -1.9, which would have been too low for admission otherwise. If EGs were only considered once, 40 (winter) and 59 (summer) applicants would have succeeded. Copyright © 2014. Published by Elsevier GmbH.

Improving drug attrition remains a challenge in pharmaceutical discovery and development. A major cause of early attrition is the demonstration of safety signals which can negate any therapeutic index previously established. Safety attrition needs to be put in context of clinical translation (i.e. human relevance) and is negatively impacted by differences between animal models and human. In order to minimize such an impact, an earlier assessment of pharmacological target homology across animal model species will enhance understanding of the context of animal safety signals and aid species selection during later regulatory toxicology studies. Here we sequenced the genomes of the Sus scrofa Göttingen minipig and the Canis familiaris beagle, two widely used animal species in regulatory safety studies. Comparative analyses of these new genomes with other key model organisms, namely mouse, rat, cynomolgus macaque, rhesus macaque, two related breeds (S. scrofa Duroc and C. familiaris boxer) and human reveal considerable variation in gene content. Key genes in toxicology and metabolism studies, such as the UGT2 family, CYP2D6, and SLCO1A2, displayed unique duplication patterns. Comparisons of 317 known human drug targets revealed surprising variation such as species-specific positive selection, duplication and higher occurrences of pseudogenized targets in beagle (41 genes) relative to minipig (19 genes). These data will facilitate the more effective use of animals in biomedical research. - Highlights: • Genomes of the minipig and beagle dog, two species used in pharmaceutical studies. • First systematic comparative genome analysis of human and six experimental animals. • Key drug toxicology genes display unique duplication patterns across species. • Comparison of 317 drug targets show species-specific evolutionary patterns.

Discrete Blood Glucose Control in Diabetic Göttingen Minipigs

Directory of Open Access Journals (Sweden)

Berno J.E. Misgeld

2016-07-01

Full Text Available Despite continuous research effort, patients with type 1 diabetes mellitus (T1D experience difficulties in daily adjustments of their blood glucose concentrations. New technological developments in the form of implanted intravenous infusion pumps and continuous blood glucose sensors might alleviate obstacles for the automatic adjustment of blood glucose concentration. These obstacles consist, for example, of large time-delays and insulin storage effects for the subcutaneous/interstitial route. Towards the goal of an artificial pancreas, we present a novel feedback controller approach that combines classical loop-shaping techniques with gain-scheduling and modern H ∞ -robust control approaches. A disturbance rejection design is proposed in discrete frequency domain based on the detailed model of the diabetic Göttingen minipig. The model is trimmed and linearised over a large operating range of blood glucose concentrations and insulin sensitivity values. Controller parameters are determined for each of these operating points. A discrete H ∞ loop-shaping compensator is designed to increase robustness of the artificial pancreas against general coprime factor uncertainty. The gain scheduled controller uses subcutaneous insulin injection as a control input and determines the controller input error from intravenous blood glucose concentration measurements, where parameter scheduling is achieved by an estimator of the insulin sensitivity parameter. Thus, only one controller stabilises a family of animal models. The controller is validated in silico with a total number of five Göttingen Minipig models, which were previously obtained by experimental identification procedures. Its performance is compared with an experimentally tested switching PI-controller.

Sudden death related to advanced coronary atherosclerosis in mini-pigs

International Nuclear Information System (INIS)

Jacobsson, L.; Lundholm, L.; Wingren, G.

1984-01-01

Advanced coronary atherosclerosis was produced in 30 mini-pigs by a combination of a hypercholesterolaemic diet and X-irradiation to the precordial region. Within 11-25 weeks after the irradiation, 13 of the 30 animals died a sudden death probably caused by coronary atherosclerosis. The contents of free and ester-bound cholesterol in the right coronary artery were significantly higher in the animals which died spontaneously than in surviving animals. In an untreated group of 12 animals 7 died whereas in a group treated with β-pyridylcarbinol only 1 out of 5 died. In the coronary arteries, the contents of both free and ester-bound cholesterol were significantly lower in the β-pyridylcarbinol-treated animals. In a sulfinpyrazontreated group 3 out of 8, and in a metoprolol-treated group 2 out of 5 animals died. None of these drugs reduced the accumulation of cholesterol in the coronary arteries. The rate of sudden death was 26 +- 6% (P<0.05) lower in the combined group of treated animals than in the untreated ones. By regular ECG recordings, signs which could predict the fatal outcome of the experiment were looked for. Although depressed ST segments were present before death in a few animals, this was not a regular phenomenon. It is concluded that advanced coronary atherosclerosis in mini-pigs often leads to sudden death and that this animal model seems suitable for testing the potential therapeutic effects of drugs.

storages of vitamin D3 two studies were carried out in Göttingen minipigs. In study 1 one group of minipigs (n=2) was daily exposed to UV light corresponding to 10–20min of midday sun and another group (n=2) of pigs were fed up to 60μg vitamin D3/day corresponding to 3.7–4.4μg/kg body weight.Study 1......-hydroxy vitamin D3 in serum and skin- and subcutaneous adipose tissue biopsies were repeatedly monitored.

Extended Microbiological Characterization of Göttingen Minipigs in the Context of Xenotransplantation: Detection and Vertical Transmission of Hepatitis E Virus.

Directory of Open Access Journals (Sweden)

Vladimir A Morozov

Full Text Available Xenotransplantation has been proposed as a solution to the shortage of suitable human donors. Pigs are currently favoured as donor animals for xenotransplantation of cells, including islet cells, or organs. To reduce the xenotransplantation-associated risk of infection of the recipient the pig donor should be carefully characterised. Göttingen minipigs from Ellegaard are often used for biomedical research and are regularly tested by their vendor for the presence of numerous bacteria, fungi, viruses and parasites. However, screening for some pathogens transmittable to humans had not been performed.The presence of microorganisms was examined in Göttingen Minipigs by PCR methods. Since zoonotic transmission of porcine hepatitis E virus HEV to humans has been demonstrated, extended search for HEV was considered as a priority. RNA from sera, islet and other cells from 40 minipigs were examined for HEV using different real-time reverse transcription (RT-PCRs, among them two newly established. In addition, sera were examined by Western blot analysis using two recombinant capsid proteins of HEV as antigens. HEV RNA was not detected in pigs older than one year including gilts, but it was detected in the sera of three of ten animals younger than 1 year. Furthermore, HEV was also detected in the sera of three sows six days after delivery and their offspring, indicating vertical transmission of the virus. PCR amplicons were cloned, sequenced and the viruses were found to belong to the HEV genotype (gt 3/4. Anti-HEV immunoglobulins G were detected in one sow and maternal antibodies in her six day old piglet. Since Göttingen minipigs were negative for many xenotransplantation-relevant microorganisms, they can now be classified as safe. HEV may be eliminated from the Ellegaard herd by selection of negative animals and/or by treatment of the animals.

To partially clone and compare the quantitative expression of tooth development-related gene Barx1 in different teeth of the mini-pig embryo at embryonic day 40, and to investigate the relationship between Barx1 spatial quantitative expression and tooth morphogenesis. The mini-pig Barx1 genes was partially cloned and the mRNA sequences of human Barx1 genes was aligned with expressed sequence tags (EST) of pig by basic local alignment search tool (BLAST), which were assembled with DNAman v5.2.2. With designed primers, Barx1 was partially cloned in use of reverse transcription polymerase chain reaction (PCR), and tested by BLAST with all the species in NCBI database and confirmed as one part of target gene. Laser capture microdissection was used to collect tooth samples from frozen sections which were prepared before in -80°C freezer. Real-time PCR was carried out to analyze quantitative expression in different teeth. Partial mini-pig Barx1 gene of 698 bp was cloned. Real-time PCR showed that, glyceraldehyde-3-phosphate dehydrogenase used as loading control, the figures of 2(-ΔCT) of lower deciduous incisor, canine, the third premolar and molar were 0.000 249, 0.000 715, 0.026 096 and 0.112 656, respectively. There was a trend of increasing expression from anterior to posterior teeth. Barx1 gene could be related to the number or differentiation of tooth cusps.

Refining experimental dental implant testing in the Göttingen Minipig using 3D computed tomography-A morphometric study of the mandibular canal.

Directory of Open Access Journals (Sweden)

Giuliano M Corte

Full Text Available This study reports morphometric and age-related data of the mandibular canal and the alveolar ridge of the Göttingen Minipig to avoid complications during in vivo testing of endosseus dental implants and to compare these data with the human anatomy. Using 3D computed tomography, six parameters of the mandibular canal as well as the alveolar bone height and the alveolar ridge width were measured in Göttingen Minipigs aged 12, 17 and 21 months. Our null hypothesis assumes that the age and the body mass have an influence on the parameters measured. The study found that the volume, length and depth of the mandibular canal all increase with age. The width of the canal does not change significantly with age. The body mass does not have an influence on any of the measured parameters. The increase in canal volume appears to be due to loss of deep spongy bone in the posterior premolar and molar regions. This reduces the available space for dental implantations, negatively affecting implant stability and potentially the integrity of the inferior alveolar neurovascular bundle. Dynamic anatomical changes occur until 21 months. On ethical grounds, using minipigs younger than 21 months in experimental implant dentistry is inadvisable. Paradoxically the measurements of the 12 months old pigs indicate a closer alignment of their mandibular anatomy to that of humans suggesting that they may be better models for implant studies. Given the variability in mandibular canal dimensions in similar age cohorts, the use of imaging techniques is essential for the selection of individual minipigs for dental prosthetic interventions and thus higher success rates.

Slower eating rate is independent to gastric emptying in obese minipigs.

Val-Laillet, D; Guérin, S; Malbert, C H

2010-11-02

The aim of our study was to investigate whether the altered eating behavior observed in the context of a diet-induced metabolic syndrome is related to changes of the gastric emptying and autonomic balance. Eight adult male Göttingen minipigs were subjected during 5months to ad libitum Western diet (WD). Several factors were compared between the lean (before WD) and obese conditions: general activity and eating behavior, gastric emptying, adiposity, glycemia and insulinemia during IVGTT, and heart rate variability (HRV). In our model, obesity did not alter the gastric emptying (258±26 vs. 256±14 min, P>0.10) but induced insulin resistance: increased basal insulinemia (12.6±0.8 to 36.6±6.1 mU/l, P5E-4±0.7E-4 to 2.5E-4±0.2E-4 min(-1) per mU.l(-1) of insulin, P0.10). Fed ad libitum with WD, animals overate durably (P<0.001). During a 30-min meal test though, the ingestion speed, the food ingested (1076±48 vs. 520±52 g) and energy intake decreased in the obese condition (P<0.05), which can be explained by the fragmentation of the daily caloric intake. These data suggest that the slower eating rate and increased number of meals observed in obese minipigs without neuropathy is independent to gastric emptying. The explanation may be sought rather in central modifications induced by obesity that might modify the food perception and/or motivation. Copyright © 2010 Elsevier Inc. All rights reserved.

Miglyol 812(®), a mixture of medium-chain triglycerides, has been identified as an oral vehicle that could improve the solubility and possibly the bioavailability of orally administered drugs during the non-clinical safety assessment. The toxicity of Miglyol was assessed in Göttingen(®) minipigs upon daily oral administration (gavage) for six weeks, at dosing-volumes of 0.5 and 2 mL/kg/day, compared to controls receiving 0.5% CarboxyMethylCellulose/0.1% Tween(®) 80 in water at 2 mL/kg/day. The control vehicle did not induce any findings. Miglyol at 0.5 and 2 mL/kg/day induced transient tremors, abnormal color of feces and increase in triglycerides. Miglyol at 2 ml/kg/day also induced reduced motor activity, decreased food intake, respiratory signs (2/6 animals) and increased total and LDL-cholesterol. At necropsy, the lung of 3/6 animals treated at 2 mL/kg/day presented abnormal color and/or irregular surface correlated with a chronic bronchiolo-alveolar inflammation. This finding is probably due to aspiration pneumonia in relation to the administration method and the high viscosity of Miglyol. Overall, the oral administration of pure Miglyol 812(®) for six weeks up to 2 mL/kg was less tolerated than that of the control vehicle. Miglyol as vehicle for sub-chronic oral toxicity studies in minipigs should be used with a limited dosing-volume. Copyright © 2015 Elsevier Inc. All rights reserved.

Prececal digestibility of various sources of starch in minipigs with or without experimentally induced exocrine pancreatic insufficiency.

Science.gov (United States)

Mösseler, A; Kramer, N; Becker, C; Gregory, P C; Kamphues, J

2012-12-01

Low prececal digestibility of starch leads to a higher starch flux into the hindgut, causing a forced microbial fermentation, energy losses, and meteorism. For exocrine pancreatic insufficiency (EPI), lack of pancreatic amylase can be compensated mostly by hindgut fermentation of starch. Even in pigs with complete loss of pancreatic secretion, starch digestibility over the entire tract is reaching levels of controls. To optimize diets for human patients with EPI, the proportion of starch that is digested by the ileum is important. Minipigs were fitted with an ileocecal reentrant fistula (n = 8) to determine prececal digestibility of starch. In 5 minipigs the pancreatic duct was ligated (PL) to induce EPI; 3 minipigs served as controls (Con). Various starch sources were tested in a 1-d screening test; therefore, disappearance rate (DR) instead of digestibility was used. Test meals consisted of 169 g DM of a basal diet plus 67.5 g DM of the starch (without thermal treatment; purified; starch content of 89 to 94.5%) and Cr(2)O(3). The test meal contained (% of DM) starch, 67; crude fat, 1.69; CP, 15; crude fiber, 2.0; and Cr(2)O(3), 0.25. In PL, prececal DR of starch was lower than in Con (P 90%) but was lower (P < 0.05) for potato (Solanum tuberosum) starch (75.4%). In PL, prececal DR of starch was higher (P < 0.05) for wheat (Triticum aestivum) starch (61.2%) than corn (Zea mays) starch (43.0%) and rice (Oryza sativa) starch (29.2%) and intermediate for potato and field pea (Pisum sativum) starch. For patients with EPI, wheat starch seems favorable due to the higher prececal digestibility whereas raw corn and rice starch should be avoided.

A transthoracic infection involving a low dose of Mycobacterium tuberculosis has been used to establish a new model of infection in minipigs. The 20-week monitoring period showed a marked Th1 response and poor humoral response for the whole infection. A detailed histopathological analysis was performed after slicing the formalin-fixed whole lungs of each animal. All lesions were recorded and classified according to their microscopic aspect, their relationship with the intralobular connective network and their degree of maturity in order to obtain a dissemination ratio (DR) between recent and old lesions. CFU counts and evolution of the DR with time showed that the proposed model correlated with a contained infection, decreasing from week 9 onwards. These findings suggest that the infection induces an initial Th1 response, which is followed by local fibrosis and encapsulation of the granulomas, thereby decreasing the onset of new lesions. Two therapeutic strategies were applied in order to understand how they could influence the model. Thus, chemotherapy with isoniazid alone helped to decrease the total number of lesions, despite the increase in DR after week 9, with similar kinetics to those of the control group, whereas addition of a therapeutic M. tuberculosis fragment-based vaccine after chemotherapy increased the Th1 and humoral responses, as well as the number of lesions, but decreased the DR. By providing a local pulmonary structure similar to that in humans, the mini-pig model highlights new aspects that could be key to a better understanding tuberculosis infection control in humans.

Growth hormone (GH) is an anabolic mitogen with widespread influence on cellular growth and differentiation as well as on glucose and lipid metabolism. GH binding to the growth hormone receptor (GHR) on hepatocytes prompts expression of insulin growth factor I (IGF-1) involved in nutritionally induced compensatory hyperplasia of pancreatic β-cell islets and insulin release. A prolonged hyperactivity of the IGF-1/insulin axis in the face of insulinotropic nutrition, on the other hand, can lead to collapse of the pancreatic islets and glucose intolerance. Individuals with Laron syndrome carry mutations in the GHR gene resulting in severe congenital IGF-1 deficiency and elevated GH serum levels leading to short stature as well as perturbed lipid and glucose metabolism. However, these individuals enjoy a reduced prevalence of acne, cancer and possibly diabetes. Minipigs have become important biomedical models for human conditions due to similarities in organ anatomy, physiology, and metabolism relative to humans. The purpose of this study was to generate transgenic Wuzhishan minipigs by handmade cloning with impaired systemic GHR activity and assess their growth profile and glucose metabolism. Transgenic minipigs featuring overexpression of a dominant-negative porcine GHR (GHR(dm)) presented postnatal growth retardation and proportionate dwarfism. Molecular changes included elevated GH serum levels and mild hyperglycemia. We believe that this model may prove valuable in the study of GH functions in relation to cancer, diabetes and longevity.

This study aimed to develop a new auxiliary heterotopic partial liver transplantation (AHPLT) technique in minipigs using a model of liver cirrhosis. Based on our previous study, 14 minipigs were induced to cirrhosis by administration of carbon tetrachloride (CCl4) through intraperitoneal injection. All of the cirrhotic animals were utilized as recipients. The donor’s liver was placed on the recipient’s splenic bed, and the anastomosis was performed as follows: end-to-end anastomosis between the donor’s portal vein and the recipient’s splenic vein, end-to-side anastomosis between the donor’s suprahepatic vena cava and the recipient’s suprahepatic vena cava, and end-to-end anastomosis between the donor’s hepatic artery and the recipient’s splenic artery. The common bile duct of the donor was intubated and bile was collected with an extracorporeal bag. Vital signs, portal vein pressure (PVP), hepatic venous pressure (HVP) and portal vein pressure gradient (PVPG) were monitored throughout the transplantation. All 8 minipigs that developed liver cirrhosis were utilized to establish the new AHPLT; 7 cases survived. Following the surgical intervention, the PVP and PVPG of the recipients were lower than those prior to the operation (P<0.05), whereas the PVP and PVPG of the donors increased significantly compared to those of the normal animals (P<0.05). A new operative technique for AHPLT has been successfully described herein using a model of liver cirrhosis. PMID:22969983

Sudden death related to advanced coronary atherosclerosis in mini-pigs. Influence of some drugs

Energy Technology Data Exchange (ETDEWEB)

Jacobsson, L.; Lundholm, L.; Wingren, G. (Department of Pharmacology, Linkoeping University, Linkoeping, Sweden)

Advanced coronary atherosclerosis was produced in 30 mini-pigs by a combination of a hypercholesterolaemic diet and X-irradiation to the precordial region. Within 11-25 weeks after the irradiation, 13 of the 30 animals died a sudden death probably caused by coronary atherosclerosis. The contents of free and ester-bound cholesterol in the right coronary artery were significantly higher in the animals which died spontaneously than in surviving animals. In an untreated group of 12 animals 7 died whereas in a group treated with ..beta..-pyridylcarbinol only 1 out of 5 died. In the coronary arteries, the contents of both free and ester-bound cholesterol were significantly lower in the ..beta..-pyridylcarbinol-treated animals. In a sulfinpyrazontreated group 3 out of 8, and in a metoprolol-treated group 2 out of 5 animals died. None of these drugs reduced the accumulation of cholesterol in the coronary arteries. The rate of sudden death was 26 +- 6% (P<0.05) lower in the combined group of treated animals than in the untreated ones. By regular ECG recordings, signs which could predict the fatal outcome of the experiment were looked for. Although depressed ST segments were present before death in a few animals, this was not a regular phenomenon. It is concluded that advanced coronary atherosclerosis in mini-pigs often leads to sudden death and that this animal model seems suitable for testing the potential therapeutic effects of drugs.

PKD1 and PKD2 mutations could lead to autosomal dominant polycystic kidney disease (ADPKD), which afflicts millions of people worldwide. Due to the marked differences in the lifespan, size, anatomy, and physiology from humans, rodent ADPKD models cannot fully mimic the disease. To obtain a large animal model that recapitulates the disease, we constructed a mini-pig model by mono-allelic knockout (KO) of PKD1 using zinc finger nuclease. The mono-allelic KO pigs had lower PKD1 expression than t...

Self-tapping of magnesium screws in hard bone may be a challenge due to the limited torsional strength of magnesium alloys in comparison with titanium. To avoid screw failure upon implantation, the new concept of a rivet-screw was applied to a WE43 magnesium alloy. Hollow cylinders with threads on the outside were expanded inside drill holes of minipig mandibles. During the expansion with a hexagonal mandrel, the threads engaged the surrounding bone and the inside of the screw transformed into a hexagonal screw drive to allow further screwing in or out of the implant. The in vivo degradation of the magnesium implants and the performance of the used coating were studied in a human standard-sized animal model. Four magnesium alloy rivet-screws were implanted in each mandible of 12 minipigs. Six animals received the plasmaelectrolytically coated magnesium alloy implants; another six received the uncoated magnesium alloy rivet-screws. Two further animals received one titanium rivet-screw each as control. In vivo radiologic examination was performed at one, four, and eight weeks. Euthanasia was performed for one group of seven animals (three animals with coated, three with uncoated magnesium alloy implants and one with titanium implant) at 12 weeks and for the remaining seven animals at 24 weeks. After euthanasia, micro-computed tomography and histological examination with histomorphometry were performed. Significantly less void formation as well as higher bone volume density (BV/TV) and bone-implant contact area (BIC) were measured around the coated implants compared to the uncoated ones. The surface coating was effective in delaying degradation despite plastic deformation. The results showed potential for further development of magnesium hollow coated screws for bone fixation. - Highlights: • A new concept of rivet screws as an alternative to classical screws is presented • The rivet screw concept was tested in vivo in a mini-pig pilot study • Un-coated and

Full Text Available Objective Adipose tissue is no longer considered as an inert storage organ for lipid, but instead is thought to play an active role in regulating insulin effects via secretion adipokines. However, conflicting reports have emerged regarding the effects of adipokines. In this study, we investigated the role of adipokines in glucose metabolism and insulin sensitivity in obese Bama mini-pigs. Methods An obesity model was established in Bama mini-pigs, by feeding with high-fat and high-sucrose diet for 30 weeks. Plasma glucose and blood biochemistry levels were measured, and intravenous glucose tolerance test was performed. Adipokines, including adiponectin, interleukin-6 (IL-6, resistin and tumor necrosis factor alpha (TNF-α, and glucose-induced insulin secretion were also examined by radioimmunoassay. AMP-activated protein kinase (AMPK phosphorylation in skeletal muscle, which is a useful insulin resistance marker, was examined by immunoblotting. Additionally, associations of AMPK phosphorylation with plasma adipokines and homeostasis model assessment of insulin resistance (HOMA-IR index were assessed by Pearce’s correlation analysis. Results Obese pigs showed hyperglycemia, high triglycerides, and insulin resistance. Adiponectin levels were significantly decreased (p<0.05 and IL-6 amounts dramatically increased (p<0.05 in obese pigs both in serum and adipose tissue, corroborating data from obese mice and humans. However, circulating resistin and TNF-α showed no difference, while the values of TNF-α in adipose tissue were significantly higher in obese pigs, also in agreement with data from obese humans but not rodent models. Moreover, strong associations of skeletal muscle AMPK phosphorylation with plasma adiponectin and HOMA-IR index were obtained. Conclusion AMPK impairment induced by adiponectin decrease mediates insulin resistance in high-fat and high-sucrose diet induction. In addition, Bama mini-pig has the possibility of a conformable

Highly efficient generation of GGTA1 biallelic knockout inbred mini-pigs with TALENs.

Full Text Available Inbred mini-pigs are ideal organ donors for future human xenotransplantations because of their clear genetic background, high homozygosity, and high inbreeding endurance. In this study, we chose fibroblast cells from a highly inbred pig line called Banna mini-pig inbred line (BMI as donor nuclei for nuclear transfer, combining with transcription activator-like effector nucleases (TALENs and successfully generated α-1,3-galactosyltransferase (GGTA1 gene biallelic knockout (KO pigs. To validate the efficiency of TALEN vectors, in vitro-transcribed TALEN mRNAs were microinjected into one-cell stage parthenogenetically activated porcine embryos. The efficiency of indel mutations at the GGTA1-targeting loci was as high as 73.1% (19/26 among the parthenogenetic blastocysts. TALENs were co-transfected into porcine fetal fibroblasts of BMI with a plasmid containing neomycin gene. The targeting efficiency reached 89.5% (187/209 among the survived cell clones after a 10 d selection. More remarkably 27.8% (58/209 of colonies were biallelic KO. Five fibroblast cell lines with biallelic KO were chosen as nuclear donors for somatic cell nuclear transfer (SCNT. Three miniature piglets with biallelic mutations of the GGTA1 gene were achieved. Gal epitopes on the surface of cells from all the three biallelic KO piglets were completely absent. The fibroblasts from the GGTA1 null piglets were more resistant to lysis by pooled complement-preserved normal human serum than those from wild-type pigs. These results indicate that a combination of TALENs technology with SCNT can generate biallelic KO pigs directly with high efficiency. The GGTA1 null piglets with inbred features created in this study can provide a new organ source for xenotransplantation research.

Purpose: We are characterizing the Gottingen minipig as an additional large animal model for advanced drug testing for the acute radiation syndrome (ARS) to enhance the discovery and development of novel radiation countermeasures. Among the advantages provided by this model, the similarities to human hematologic parameters and dynamics of cell loss/recovery after irradiation provide a convenient means to compare the efficacy of drugs known to affect bone marrow cellularity and hematopoiesis. Methods and Materials: Male Gottingen minipigs, 4 to 5 months old and weighing 9 to 11 kg, were used for this study. We tested the standard off-label treatment for ARS, rhG-CSF (Neupogen, 10 μg/kg/day for 17 days), at the estimated LD70/30 total-body γ-irradiation (TBI) radiation dose for the hematopoietic syndrome, starting 24 hours after irradiation. Results: The results indicated that granulocyte colony stimulating factor (G-CSF) enhanced survival, stimulated recovery from neutropenia, and induced mobilization of hematopoietic progenitor cells. In addition, the administration of G-CSF resulted in maturation of monocytes/macrophages. Conclusions: These results support continuing efforts toward validation of the minipig as a large animal model for advanced testing of radiation countermeasures and characterization of the pathophysiology of ARS, and they suggest that the efficacy of G-CSF in improving survival after total body irradiation may involve mechanisms other than increasing the numbers of circulating granulocytes.

We tested the standard off-label treatment for ARS, rhG-CSF (Neupogen, 10 μg/kg/day for 17 days), at the estimated LD70/30 total-body γ-irradiation (TBI) radiation dose for the hematopoietic syndrome, starting 24 hours after irradiation. Results: The results indicated that granulocyte colony stimulating factor (G-CSF) enhanced survival, stimulated recovery from neutropenia, and induced mobilization of hematopoietic progenitor cells. In addition, the administration of G-CSF resulted in maturation of monocytes/macrophages. Conclusions: These results support continuing efforts toward validation of the minipig as a large animal model for advanced testing of radiation countermeasures and characterization of the pathophysiology of ARS, and they suggest that the efficacy of G-CSF in improving survival after total body irradiation may involve mechanisms other than increasing the numbers of circulating granulocytes

Porcine reproductive and respiratory syndrome virus (PRRSV) infection was diagnosed in 6 G?ttingen minipigs (Sus scrofa domestica) with severe interstitial pneumonia. The virus was defined as a North American (NA) subtype virus, which is common in the commercial pig population and might be derived from a widely used attenuated live-virus vaccine in Europe. The ORF5 sequence of the isolated PRRSV was 98% identical to the vaccine virus. The affected pigs were part of a lung transplantation mode...

The energy formulation of the active contour exploits the homogeneous nature of the subcutaneous fat and the smoothness of the boundary. Subsequently the retroperitoneal fat located around the abdominal cavity......This article describes a method for automatic segmentation of the abdomen into three anatomical regions: subcutaneous, retroperitoneal and visceral. For the last two regions the amount of adipose tissue (fat) is quantified. According to recent medical research, the distinction between...... retroperitoneal and visceral fat is important for studying metabolic syndrome, which is closely related to diabetes.1 However previous work has neglected to address this point, treating the two types of fat together.

International efforts in developing a vaccine against Chlamydia trachomatis have highlighted the need for novel immunization strategies for the induction of genital immunity. In this study, we evaluated an intramuscular (IM) prime/intranasal boost vaccination strategy in a Göttingen Minipig model with a reproductive system very similar to humans. The vaccine was composed of C. trachomatis subunit antigens formulated in the Th1/Th17 promoting CAF01 adjuvant. IM priming immunizations with CAF01 induced a significant cell-mediated interferon gamma and interleukin 17A response and a significant systemic high-titered neutralizing IgG response. Following genital challenge, intranasally boosted groups mounted an accelerated, highly significant genital IgA response that correlated with enhanced bacterial clearance on day 3 post infection. By detecting antigen-specific secretory component (SC), we showed that the genital IgA was locally produced in the genital mucosa. The highly significant inverse correlation between the vaginal IgA SC response and the chlamydial load suggests that IgA in the minipig model is involved in protection against C. trachomatis. This is important both for our understanding of protective immunity and future vaccination strategies against C. trachomatis and genital pathogens in general. PMID:26734002

The biological importance of cadmium and the absorption of /sup 115m/Cd by laying hens, minipigs and monkeys

International Nuclear Information System (INIS)

Anke, M.; Hoffmann, G.; Hennig, A.; Groppel, B.; Kronemann, H.; Gruen, M.

Absorption, incorporation and distribution of /sup 115m/Cd have been studied in laying hens, minipigs and rhesus monkeys for 96 hours. 4 days after oral /sup 115m/Cd application hens stored 2.3%, minipigs 1.9% and monkeys 4% outside the digestive tract. 45 minutes after administration the hens accumulated 11% with returning to the normal 2.3% within 6 hours and up to 4 days. Skeleton, muscles, lungs, blood and feathers stored the highest Cd amounts shortly after intake. Liver, kidneys and ovaries accumulated Cd slowly with the highest amount after 96 hours. 45 minutes after intake skeleton (53%), muscles (34%) and feathers(9%) stored 96% of the totally incorporated Cd; after 96 hours only 22% of the Cd were localized in these organs, while 50% were stored in the liver and 27% in the kidneys. Per gram organ dry substance 100% were accumulated in the kidneys, 20% in the liver, 10% in the pancreas and 2% in the lungs. All other organs stored < 1% Cd with the lowest amount in the brain. Eggs and meat stored low Cd amounts not being dangerous for man. In Cd-polluted areas animals can really be used as filters for Cd if kidneys and livers are excluded from food-stuffs

To find out if adipose-derived stem cells (ASC) and platelet-rich fibrin (PRF), alone or combined, had any effect on the repair of maxillofacial soft tissue defects in irradiated minipigs, ASC were isolated, characterised, and expanded. Twenty female minipigs, the right parotid glands of which had been irradiated, were randomly divided into 4 groups of 5 each: those in the first group were injected with both ASC and PRF (combined group), the second group was injected with ASC alone (ASC group), the third group with PRF alone (PRF group), and the fourth group with phosphate buffer saline (PBS) (control group). Six months after the last injection, the size and depth of each defect were assessed, and subcutaneous tissues were harvested, stained with haematoxylin and eosin, and examined immunohistologically and for apoptosis. Expanded cells were successfully isolated and identified. Six months after injection the defects in the 3 treated groups were significantly smaller (p<0.001) and shallower (p<0.001) than those in the control group. Those in the combined group were the smallest and shallowest. Haematoxylin and eosin showed that the 3 treated groups contained more subcutaneous adipose tissue than the control group, and also had significantly greater vascular density (p<0.001) and fewer apoptotic cells (p<0.001). Both ASC and PRF facilitate the repair of defects in maxillofacial soft tissue in irradiated minipigs, and their combined use is more effective than their use as single agents.

Full Text Available Angiogenesis is part of the healing process following an ischemic injury and is vital for the post-ischemic repair of the myocardium. Therefore, it is of particular interest to be able to noninvasively monitor angiogenesis. This might, not only permit risk stratification of patients following myocardial infarction, but could also facilitate development and improvement of new therapies directed towards stimulation of the angiogenic response. During angiogenesis endothelial cells must adhere to one another to form new microvessels. αvβ3 integrin has been found to be highly expressed in activated endothelial cells and has been identified as a critical modulator of angiogenesis. 68Ga-NODAGA-E[c(RGDyK]2 (RGD has recently been developed by us as an angiogenesis positron-emission-tomography (PET ligand targeted towards αvβ3 integrin. In the present study, we induced myocardial infarction in Göttingen minipigs. Successful infarction was documented by 82Rubidium-dipyridamole stress PET and computed tomography. RGD uptake was demonstrated in the infarcted myocardium one week and one month after induction of infarction by RGD-PET. In conclusion, we demonstrated angiogenesis by noninvasive imaging using RGD-PET in minipigs hearts, which resemble human hearts. The perspectives are very intriguing and might permit the evaluation of new treatment strategies targeted towards increasing the angiogenetic response, e.g., stem-cell treatment.

The potential of buccal mucosa as a site for systemic absorption has attracted increased attention in recent years creating a need for new predictive in-vivo models. The aim of this study was to evaluate anaesthetised and conscious Göttingen mini-pigs as a model for buccal drug absorption by testing pH-dependent absorption of metoprolol from a solid dosage form. Buccal tablets buffered to pH 6.2 and pH 8.9, oral liquid and intravenous injection were tested in four conscious and anaesthetised Göttingen mini-pigs in a non-randomised cross-over study. Blood samples were collected and processed before analysis by ultra-performance liquid chromatography with tandem mass spectrometry detection. An ex-vivo flow retention model was applied to study release and retention of the bioadhesive buccal tablets. The Tmax obtained from the two buccal conscious groups (55 ± 5 and 35 ± 5 min) were significantly different to the buccal anaesthetised groups (120 ± 0 and 165 ± 15 min) for buccal tablet pH 6.2 and pH 8.9, respectively. Also, the absolute bioavailability from the anaesthetised buccal tablet pH 8.9 (20.7 ± 4.0%) had a significant increase compared to all other buccal tablet groups. In conclusion, this study showed a pH-dependent absolute bioavailability of metoprolol when administrated as bioadhesive buccal tablets to anaesthetised mini-pigs. The anaesthesia was found to delay the time to reach maximal plasma concentration of metoprolol as compared to the conscious pig model when administrated as buccal tablets.

Therefore, we studied the expression of innate immune genes in liver and adipose tissues as well as serum concentrations of cytokines and acute phase proteins in obese vs. lean Göttingen minipigs. In the liver, of 35 investigated genes, the expression of nine...... was significantly different in obese pigs (three up-regulated, six down-regulated). Of 33 genes in adipose tissues, obesity was associated with changed expression of 12 genes in the visceral adipose tissue (VAT) (three up-regulated), 11 in the abdominal retroperitoneal adipose tissue (RPAT) (seven of these up......-regulated) and eight in the subcutaneous adipose tissue (SAT) from the neck (five of which were up-regulated). Obesity-associated expression changes were observed for three genes in all adipose tissues, namely chemokine (C-C motif) ligand 3-like 1 (up-regulated), CD200 molecule (down-regulated) and interleukin 1...

Purpose. To evaluate trisacryl-gelatin microspheres (40-120 μm) for acute and chronic tissue embolization in mini-pig livers. Methods. Thirteen animals were divided into four groups: group 1 (n = 3), total arterial bed occlusion with acute procedure; groups 2 to 4, chronic superselective embolization with follow-up of 1 week (group 2, n = 1), 4 weeks (group 3, n 4) or 14 weeks (group 4, n = 5). Key endpoints were homogeneity and particle distribution in acute embolizations (group 1) and necrosis and inflammation in chronic embolizations (groups 2-4) as assessed microscopically and angiographically. Results. After liver embolization, parenchymal necrosis did not occur; only signs of vessel wall disintegration were evident. The bile ducts remained intact. A distinct foreign body reaction with sparse leukocytic infiltration and giant cells was found at 14 weeks, but no signs of major inflammation were found. Particles were seen at the presinusoidal level, but no particle transportation into the sinusoids was observed. Conclusions. Embolization in mini-pig livers, using small trisacryl-gelatin microspheres, results in vessel fibrosis without parenchymal or bile duct necrosis. The most likely explanation for preservation of the parenchyma is portal inflow. Small trisacryl-gelatin microspheres may be ideal as an adjunct for chemoembolization

To implant deep brain stimulation (DBS) electrodes in the porcine pontine micturition centre (PMC) in order to establish a large animal model of PMC-DBS. Brain stems from four Göttingen minipigs were sectioned coronally into 40-mum-thick histological sections and stained with Nissl, auto-metallographic myelin stain, tyrosine hydroxylase and corticotrophin-releasing factor immunohistochemistry in order to identify the porcine PMC. DBS electrodes were then stereotaxically implanted on the right side into the PMC in four Göttingen minipigs, and the bladder response to electrical stimulation was evaluated by subsequent cystometry performed immediately after the operation and several weeks later. A paired CRF-dense area homologous to the PMC in other species was encountered in the rostral pontine tegmentum medial to the locus coeruleus and ventral to the floor of the fourth ventricle. Electrical stimulation of the CRF-dense area resulted in an increased detrusor pressure followed by visible voiding in some instances. The pigs were allowed to survive between 14 and 55 days, and electrical stimulation resulting in an increased detrusor pressure was performed on more than one occasion without affecting consciousness or general thriving. None of the pigs developed postoperative infections or died prematurely. DBS electrodes can be implanted for several weeks in the identified CRF-dense area resulting in a useful large animal model for basic research on micturition and the future clinical use of this treatment modality in neurogenic supra-pontine voiding disorders.

To document the sequence of bone formation in a minipig model of Le Fort I distraction osteogenesis (DO) using immunohistochemistry and histomorphometry. Female Yucatan minipigs (N = 9) in the mixed-dentition stage underwent bilateral maxillary DO. The distraction protocol was 0 days of latency, with a distraction rate of 1 mm/d for 12 days and 24 days of fixation. Specimens were harvested and divided between the central incisors (18 hemi-maxillae) at the end of DO (n = 6), at mid-fixation (n = 6), and at the end of fixation (n = 6). Sections, including the advancement zone, were stained with hematoxylin-eosin, collagen II, CD34, proliferating cell nuclear antigen, and tartrate-resistant acid phosphatase. Light and fluorescence microscope images (original magnification ×200) were obtained, and percentage of surface area (PSA) of the advancement zone occupied by fibrous tissue, vessels, proliferating cells, osteoid, and bone was determined. An intact maxilla served as the control. At the end of DO, in the advancement zone, the PSA (mean values) of proliferating cells was 33.16%; fibrous tissue, 52%; vessels, 4.35%; and new bone, 5.45%. At the end of fixation, the PSA of proliferating cells decreased to 10.53%, fibrous tissue to 2.3%, and vessels to 1.5% whereas the PSA of new bone increased to 44.9%. The results of this study indicate that the progression of osteogenesis in the maxillary DO wound begins with intense cellular proliferation and vascular fibrous tissue formation and progresses to mature, cancellous bone by the end of fixation. The PSA occupied by mature bone is significantly less than in the control maxilla at the end of fixation. This is consistent with the sequence in the mandibular DO wound. Published by Elsevier Inc.

Current treatment of obstructive jaundice includes endoscopic stenting and open surgical bypass. To combine the advantages of surgical bypass with the minimal invasive approach of endoscopic stenting we developed a laparoscopic technique, transient endoluminally stented anastomosis (TESA). As shown previously, small-diameter anastomoses (e.g., hepaticojejunostomy) by TESA technique can be performed reliably in growing domestic swine. This further preclinical trial was designed to exclude growth of the animals as the main reason for these excellent results. After ligation of the common bile duct, a laparoscopic Roux-en-y hepaticojejunostomy was performed 7 days later by TESA with a reabsorbable radiopaque polyglycolic acid stent. In group A (n = 7) growing domestic pigs and in group B (n = 5) adult minipigs were operated on. Laboratory parameters were controlled weekly. Stent degradation was followed by weekly abdominal x-ray. At necropsy 6 months after surgery, cholangiography was performed and the anastomoses were measured. Mean weight gain was 140.7 +/- 10.9 kg in domestic pigs versus 5.8 +/- 1.6 kg in minipigs. Cholestasis normalized within 7 days postoperatively. Duration of stenting was not significantly different between groups. Cholangiography at necropsy showed immediate runoff through the anastomoses in both groups. The diameter of the anastomosis was 4.7 +/- 0.5 mm in group A versus 3.0 +/- 0.4 mm in group B (p = 0.03). In conclusion, functionality of the small-diameter TESA hepaticojejunostomy is not related to age and growing factors in pigs, justifying its application in human as the next step of investigation.

To date, only silicone oils and gases have the appropriate characteristics for use in vitreo-retinal surgery as vitreous substitutes with intraocular tamponading properties. This preliminary study evaluated the safety and efficacy of medium-chain triglycerides (MCTs) for use as a tamponading agent in minipigs. In 15 minipigs, 15 right eyes underwent vitrectomies followed by injection of MCT tamponade (day 1). Two groups were defined. In Group A (ten eyes), the surgical procedure before MCT injection included induced rhegmatogenous retinal detachment (RRD), retina flattening, and retinopexy. In Group B (five eyes), MCT was injected without inducing RRD; in these eyes, MCT was removed on day 90. Pigs were sacrificed on day 45 (Group A) or 120 (Group B). Eyes were examined on days 1, 5, 15, and 45 in both groups and on days 90 and 120 in Group B. In Group B only, we performed bilateral electroretinography examinations on days 1 and 120, and histological examinations of MCTs and controlateral eyes were performed after sacrifice. In Group A eyes (n = 9; one eye was non-assessable), on day 45, the retina was flat in seven eyes and two RRD detachments were observed in insufficiently MCT-filled eyes. In Group B, electroretinography showed no significant differences between MCT eyes and controls on days 1 or 120. Histological analyses revealed no signs of retinal toxicity. This study showed that MCT tamponade seems to be effective and safe; however, additional studies are needed before it becomes commonly used as a tamponading agent in humans.

Effects of Obesity and Metabolic Syndrome on Steroidogenesis and Folliculogenesis in the Female Ossabaw Mini-Pig.

Directory of Open Access Journals (Sweden)

Annie E Newell-Fugate

Full Text Available The discrete effects of obesity on infertility in females remain undefined to date. To investigate obesity-induced ovarian dysfunction, we characterized metabolic parameters, steroidogenesis, and folliculogenesis in obese and lean female Ossabaw mini-pigs. Nineteen nulliparous, sexually mature female Ossabaw pigs were fed a high fat/cholesterol/fructose diet (n=10 or a control diet (n=9 for eight months. After a three-month diet-induction period, pigs remained on their respective diets and had ovarian ultrasound and blood collection conducted during a five-month study period after which ovaries were collected for histology, cell culture, and gene transcript level analysis. Blood was assayed for steroid and protein hormones. Obese pigs developed abdominal obesity and metabolic syndrome, including hyperglycemia, hypertension, insulin resistance and dyslipidemia. Obese pigs had elongated estrous cycles and hyperandrogenemia with decreased LH, increased FSH and luteal phase progesterone, and increased numbers of medium, ovulatory, and cystic follicles. Theca cells of obese, compared to control, pigs displayed androstenedione hypersecretion in response to in vitro treatment with LH, and up-regulated 3-beta-hydroxysteroid dehydrogenase 1 and 17-beta-hydroxysteroid dehydrogenase 4 transcript levels in response to in vitro treatment with LH or LH + insulin. Granulosa cells of obese pigs had increased 3-beta-hydroxysteroid dehydrogenase 1 transcript levels. In summary, obese Ossabaw pigs have increased transcript levels and function of ovarian enzymes in the delta 4 steroidogenic pathway. Alterations in LH, FSH, and progesterone, coupled with theca cell dysfunction, contribute to the hyperandrogenemia and disrupted folliculogenesis patterns observed in obese pigs. The obese Ossabaw mini-pig is a useful animal model in which to study the effects of obesity and metabolic syndrome on ovarian function and steroidogenesis. Ultimately, this animal model may be

High failure rates of oral implants have been reported in diabetic patients due to the disruption of osseointegration. The aim of this study was to investigate whether direct laser metal sintering (DLMS) could improve osseointegration in diabetic animal models. Surface characterizations were carried out on two types of implants. Cell morphology and the osteogenic-related gene expression of MG63 cells were observed under conditions of DLMS and microarc oxidation (MAO). A diabetes model in mini-pigs was established by intravenous injection of streptozotocin (150 mg/kg), and a total of 36 implants were inserted into the mandibular region. Micro-computed tomography (micro-CT) and histologic evaluations were performed 3 and 6 months after implantation. The Ra (the average of the absolute height of all points) of MAO surface was 2.3±0.3 µm while the DLMS surface showed the Ra of 27.4±1.1 µm. The cells on DLMS implants spread out more podia than those on MAO implants through cell morphology analysis. Osteogenic-related gene expression was also dramatically increased in the DLMS group. Obvious improvement was observed in the micro-CT and Van Gieson staining analyses of DLMS implants compared with MAO at 3 months, although this difference disappeared by 6 months. DLMS implants showed a higher bone-implant contact percentage (33.2%±11.2%) at 3 months compared with MAO group (18.9%±7.3%) while similar results were showed at 6 months between DLMS group (42.8%±10.1%) and MAO group (38.3%±10.8%). The three-dimensional environment of implant surfaces with highly porous and fully interconnected channel and pore architectures can improve cell spreading and accelerate the progress of osseointegration in diabetic mini-pigs.

Pre-pulse inhibition (PPI) of the startle response is a measure of sensorimotor gating which has been frequently shown to be deficient in schizophrenic patients. In humans it is typically measured as the attenuation of the startle eye-blink reflex EMG when a startle eliciting noise is preceded...... by a weak white noise pre-pulse (PP), the interval between the PP and the startle noise stimulus (SNS) determining the degree of inhibition.

The cartilage regeneration potential of human umbilical cord blood-derived mesenchymal stem cells (hUCB-MSCs) with a hyaluronic acid (HA) hydrogel composite has shown remarkable results in rat and rabbit models. The purpose of the present study was to confirm the consistent regenerative potential in a pig model using three different cell lines. A full-thickness chondral injury was intentionally created in the trochlear groove of each knee in 6 minipigs. Three weeks later, an osteochondral defect, 5 mm wide by 10 mm deep, was created, followed by an 8-mm-wide and 5-mm-deep reaming. A mixture (1.5 ml) of hUCB-MSCs (0.5×10(7) cells per milliliter) and 4% HA hydrogel composite was then transplanted into the defect on the right knee. Each cell line was used in two minipigs. The osteochondral defect created in the same manner on the left knee was untreated to act as the control. At 12 weeks postoperatively, the pigs were sacrificed, and the degree of subsequent cartilage regeneration was evaluated by gross and histological analysis. The transplanted knee resulted in superior and more complete hyaline cartilage regeneration compared with the control knee. The cellular characteristics (e.g., cellular proliferation and chondrogenic differentiation capacity) of the hUCB-MSCs influenced the degree of cartilage regeneration potential. This evidence of consistent cartilage regeneration using composites of hUCB-MSCs and HA hydrogel in a large animal model could be a stepping stone to a human clinical trial in the future. To date, several studies have investigated the chondrogenic potential of human umbilical cord blood-derived mesenchymal stem cells (hUCB-MSCs); however, the preclinical studies are still limited in numbers with various results. In parallel, in the past several years, the cartilage regeneration potential of hUCB-MSCs with a hyaluronic acid (HA) hydrogel composite have been investigated and remarkable results in rat and rabbit models have been attained.

Full Text Available Abstract Introduction There has been renewed interest in mushroom medicinal properties. We studied cholesterol lowering properties of Ganoderma lucidum (Gl, a renowned medicinal species. Results Organic fractions containing oxygenated lanosterol derivatives inhibited cholesterol synthesis in T9A4 hepatocytes. In hamsters, 5% Gl did not effect LDL; but decreased total cholesterol (TC 9.8%, and HDL 11.2%. Gl (2.5 and 5% had effects on several fecal neutral sterols and bile acids. Both Gl doses reduced hepatic microsomal ex-vivo HMG-CoA reductase activity. In minipigs, 2.5 Gl decreased TC, LDL- and HDL cholesterol 20, 27, and 18%, respectively (P Conclusions Overall, Gl has potential to reduce LDL cholesterol in vivo through various mechanisms. Next steps are to: fully characterize bioactive components in lipid soluble/insoluble fractions; evaluate bioactivity of isolated fractions; and examine human cholesterol lowering properties. Innovative new cholesterol-lowering foods and medicines containing Gl are envisioned.

To investigate the expression and distribution of xenoantigen in intervertebral disk of Chinese banna minipig inbred line, and to study the availability of xenograft transplantation of intervertebral disk. Samples of intervertebral disk were collected from six Banna pigs of 8 to 11-month-old. The fixation, embedment and slice were performed. alpha-Gal specific binding lection (BSI-B4) were used as affinity reagents and affinity-immunohistochemistry assays (SABC methods and DAB stain) were conducted to detect the expression and distribution of xenoantigen (alpha-Gal). alpha-Gal was found in chondrocyte cell and chondrocyte-like cell in intervertebral disk which have the positive yellow-stained particulate aggradation. There was no stain in the matrix, elastic fiber and collagen fiber. The distribution of xenoantigen is locally in the tissue of intervertebral disk and its expression is weak. This suggests that the intervertebral disk of Banna pig may be alternative donor for xenotransplantation.

Full Text Available Aim The nanomechanical evaluation can provide additional information about the dental implants osseointegration process. The aim of this study was to quantify elastic modulus and hardness of bone around cemented-retained abutment implants positioned at two different crestal bone levels. Materials and methods The mandibular premolars of 7 minipigs were extracted. After 8 weeks, 8 implants were inserted in each animal: crestally on one side of the mandible and subcrestally on the other (crestal and subcrestal groups. Functional loading were immediately provided with abutments cementation and prostheses installation. Eight weeks later, the animals euthanasia was performed and nanoindentation analyses were made at the most coronal newly formed bone region (coronal group, and below in the threaded region (threaded group of histologic sections. Results The comparisons between subcrestal and crestal groups did not achieve statistical relevance; however the elastic modulus and hardness levels were statistically different in the two regions of evaluation (coronal and threaded. Conclusions The crestal and subcrestal placement of cement-retained abutment implants did not affect differently the nanomechanical properties of the surrounding bone. However the different regions of newly formed bone (coronal and threaded groups were extremely different in both elastic modulus and hardness, probably reflecting their differences in bone composition and structure.

Dimensional Ridge Preservation with a Novel Highly Porous TiO 2 Scaffold: An Experimental Study in Minipigs

Directory of Open Access Journals (Sweden)

Hanna Tiainen

2012-01-01

Full Text Available Despite being considered noncritical size defects, extraction sockets often require the use of bone grafts or bone graft substitutes in order to facilitate a stable implant site with an aesthetically pleasing mucosal architecture and prosthetic reconstruction. In the present study, the effect of novel TiO2 scaffolds on dimensional ridge preservation was evaluated following their placement into surgically modified extraction sockets in the premolar region of minipig mandibles. After six weeks of healing, the scaffolds were wellintegrated in the alveolar bone, and the convex shape of the alveolar crest was preserved. The scaffolds were found to partially preserve the dimensions of the native buccal and lingual bone walls adjacent to the defect site. A tendency towards more pronounced vertical ridge resorption, particularly in the buccal bone wall of the nongrafted alveoli, indicates that the TiO2 scaffold may be used for suppressing the loss of bone that normally follows tooth extraction.

Full Text Available Aim: The presence of a microgap at the implant-abutment interface may permit bacterial contamination and lead to bone resorption, interfering with papillae formation. The present study evaluated adjacent implants with cement-retained abutments as an option to control such deleterious effects. Materials and methods Seven minipigs had their bilateral mandibular premolars previously extracted. After 8 weeks, four implants were installed in each hemi-mandible of each animal. The adjacent implants were randomly inserted on one side at the crestal bone level and on the other, 1.5 mm subcrestally. Immediately, a non-submerged healing and functional loading were provided with the abutments cementation and prostheses installation. Clinical examination and histomorphometry served to analyze the implant success. Results A total of 52 implants were evaluated at the end of the study. The subcrestal group achieved statistical better results when compared to the crestal group, clinically in papillae formation (1.97 x 1.57 mm and histomorphometrically in crestal bone remodeling (1.17 x 1.63 mm, bone density (52.39 x 45.22% and bone-implant contact (54.13 x 42.46%. Conclusion The subcrestal placement of cement-retained abutment implants showed better indexes of osseointegration and also improved papillae formation and crestal bone remodeling at the interimplant area after immediate loading, making them a promising option for the treatment of esthetic regions.

TLR4 and TLR7/8 Adjuvant Combinations Generate Different Vaccine Antigen-Specific Immune Outcomes in Minipigs when Administered via the ID or IN Routes.

Paul F McKay

Full Text Available The induction of high levels of systemic and mucosal humoral immunity is a key goal for many prophylactic vaccines. However, adjuvant strategies developed in mice have often performed poorly in the clinic. Due to their closer similarity to humans, minipigs may provide a more accurate picture of adjuvant performance. Based on their complementary signalling pathways, we assessed humoral immune responses to model antigens after co-administration with the toll-like receptor 4 (TLR4 stimulator glucopyranosyl lipid adjuvant (GLA-AF or the TLR7/8 agonist resiquimod (R848 (alone and in combination via the intradermal (ID, intranasal (IN or combined routes in the Gottingen minipig animal model. Surprisingly, we discovered that while GLA-AF additively enhanced the adjuvant effect of R848 when injected ID, it abrogated the adjuvant activity of R848 after IN inoculation. We then performed a route comparison study using a CN54 gp140 HIV Envelope model antigen adjuvanted with R848 + GLA-AF (ID or R848 alone (IN. Animals receiving priming inoculations via one route were then boosted by the alternate route. Although differences were observed in the priming phase (IN or ID, responses converged upon boosting by the alternative route with no observable impact resultant from the order of administration (ID/IN vs IN/ID. Specific IgG responses were measured at a distal mucosal site (vaginal, although there was no evidence of mucosal linkage as these closely reflected serum antibody levels. These data indicate that the complex in vivo cross-talk between innate pathways are likely tissue specific and cannot be predicted by simple in vitro models.

Full Text Available Cutaneous radiation syndrome (CRS is the delayed consequence of localized skin exposure to high doses of ionizing radiation. Here we examined for the first time in a large animal model the therapeutic potential of autologous adipose tissue-derived stroma cells (ASCs. For experiments, Göttingen minipigs were locally gamma irradiated using a (60Co source at the dose of 50 Gy and grafted (n = 5 or not (n = 8. ASCs were cultured in MEM-alpha with 10% fetal calf serum and basic fibroblast growth factor (2 ng.mL(-1 and post irradiation were intradermally injected on days 25, 46, 67 and finally between days 95 and 115 (50 × 10(6 ASCs each time into the exposed area. All controls exhibited a clinical evolution with final necrosis (day 91. In grafted pigs an ultimate wound healing was observed in four out of five grafted animals (day 130 +/- 28. Immunohistological analysis of cytokeratin expression showed a complete epidermis recovery. Grafted ASCs accumulated at the dermis/subcutis barrier in which they attracted numerous immune cells, and even an increased vasculature in one pig. Globally this study suggests that local injection of ASCs may represent a useful strategy to mitigate CRS.

Hydroxyapatite (HA) ceramics are widely used for bone reconstruction. They are osteoconductive and serve as structural scaffolds for the deposition of new bone. Generally, scaffold materials should be degradable as they affect the mechanical properties of the reconstructed bone negatively. Degradation by osteoclasts during the bone remodelling process is desirable but often does not take place. In the current study we analysed by light microscopy the degradation of two granular HA implants in critically sized defects in the mandibula of Goettingen mini-pigs five weeks after implantation. Bio-Oss consists of sintered bovine bone and NanoBone is a synthetic HA produced in a sol-gel process in the presence of SiO2. We found that both biomaterials were degraded by osteoclasts with ruffled borders and acid phosphatase activity. The osteoclasts created resorption lacunae and resorptive trails and contained mineral particles. Frequently, resorption surfaces were in direct contact with bone formative surfaces on one granule. Granules, especially of NanoBone, were also covered by osteoclasts if located in vascularised connective tissue distant from bone tissue. However, this usually occurred without the creation of resorption lacunae. The former defect margins consisted of newly formed bone often without remnants of bone substitutes. Our results show that the degradation of both biomaterials corresponds to the natural bone degradation processes and suggest the possibility of complete resorption during bone remodelling.

The aim of this study was to investigate whether direct laser metal sintering (DLMS could improve osseointegration in diabetic animal models. Methods: Surface characterizations were carried out on two types of implants. Cell morphology and the osteogenic-related gene expression of MG63 cells were observed under conditions of DLMS and microarc oxidation (MAO. A diabetes model in mini-pigs was established by intravenous injection of streptozotocin (150 mg/kg, and a total of 36 implants were inserted into the mandibular region. Micro-computed tomography (micro-CT and histologic evaluations were performed 3 and 6 months after implantation. Results: The Ra (the average of the absolute height of all points of MAO surface was 2.3±0.3 µm while the DLMS surface showed the Ra of 27.4±1.1 µm. The cells on DLMS implants spread out more podia than those on MAO implants through cell morphology analysis. Osteogenic-related gene expression was also dramatically increased in the DLMS group. Obvious improvement was observed in the micro-CT and Van Gieson staining analyses of DLMS implants compared with MAO at 3 months

Although steatorrhea is the most obvious symptom of pancreatic exocrine insufficiency (PEI), enzymatic digestion of protein and starch is also impaired. Low praecaecal digestibility of starch causes a forced microbial fermentation accounting for energy losses and meteorism. To optimise dietetic measures, knowledge of praecaecal digestibility of starch is needed but such information from PEI patients is rare. Minipigs fitted with an ileocaecal fistula with (n = 3) or without (n = 3) pancreatic duct ligation (PL) were used to estimate the rate of praecaecal disappearance (pcD) of starch. Different botanical sources of starch (rice, amaranth, potato, and pea) were fed either raw or cooked. In the controls (C), there was an almost complete pcD (>92%) except for potato starch (61.5%) which was significantly lower. In PL pcD of raw starch was significantly lower for all sources of starch except for amaranth (87.9%). Thermal processing increased pcD in PL, reaching values of C for starch from rice, potato, and pea. This study clearly underlines the need for precise specification of starch used for patients with specific dietetic needs like PEI. Data should be generated in suitable animal models or patients as tests in healthy individuals would not have given similar conclusions.

Sexually transmitted diseases constitute major health issues and their prevention and treatment continue to challenge the health care systems worldwide. Animal models are essential for a deeper understanding of the diseases and the development of safe and protective vaccines. Currently a good predictive non-rodent model is needed for the study of genital chlamydia in women. The pig has become an increasingly popular model for human diseases due to its close similarities to humans. The aim of this review is to compare the porcine and human female genital tract and associated immune system in the perspective of genital Chlamydia infection. The comparison of women and sows has shown that despite some gross anatomical differences, the structures and proportion of layers undergoing cyclic alterations are very similar. Reproductive hormonal cycles are closely related, only showing a slight difference in cycle length and source of luteolysing hormone. The epithelium and functional layers of the endometrium show similar cyclic changes. The immune system in pigs is very similar to that of humans, even though pigs have a higher percentage of CD4(+)/CD8(+) double positive T cells. The genital immune system is also very similar in terms of the cyclic fluctuations in the mucosal antibody levels, but differs slightly regarding immune cell infiltration in the genital mucosa - predominantly due to the influx of neutrophils in the porcine endometrium during estrus. The vaginal flora in Göttingen Minipigs is not dominated by lactobacilli as in humans. The vaginal pH is around 7 in Göttingen Minipigs, compared to the more acidic vaginal pH around 3.5-5 in women. This review reveals important similarities between the human and porcine female reproductive tracts and proposes the pig as an advantageous supplementary model of human genital Chlamydia infection.

Comparison of minipig, dog, monkey and human drug metabolism and disposition.

Dalgaard, Lars

2015-01-01

This article gives an overview of the drug metabolism and disposition (ADME) characteristics of the most common non-rodent species used in toxicity testing of drugs (minipigs, dogs, and monkeys) and compares these to human characteristics with regard to enzymes mediating the metabolism of drugs and the transport proteins which contribute to the absorption, distribution and excretion of drugs. Literature on ADME and regulatory guidelines of relevance in drug development of small molecules has been gathered. Non-human primates (monkeys) are the species that is closest to humans in terms of genetic homology. Dogs have an advantage due to the ready availability of comprehensive background data for toxicological safety assessment and dogs are easy to handle. Pigs have been used less than dogs and monkeys as a model in safety assessment of drug candidates. However, when a drug candidate is metabolised by aldehyde oxidase (AOX1), N-acetyltransferases (NAT1 and NAT2) or cytochrome (CYP2C9-like) enzymes which are not expressed in dogs, but are present in pigs, this species may be a better choice than dogs, provided that adequate exposure can be obtained in pigs. Conversely, pigs might not be the right choice if sulfation, involving 3-phospho-adenosyl-5-phosphosulphate sulphotransferase (PAPS) is an important pathway in the human metabolism of a drug candidate. In general, the species selection should be based on comparison between in vitro studies with human cell-based systems and animal-cell-based systems. Results from pharmacokinetic studies are also important for decision-making by establishing the obtainable exposure level in the species. Access to genetically humanized mouse models and highly sensitive analytical methods (accelerator mass spectrometry) makes it possible to improve the chance of finding all metabolites relevant for humans before clinical trials have been initiated and, if necessary, to include another animal species before long term toxicity studies are

Prosthetic annuloplasty rings are a common treatment modality for mitral regurgitation, and recently, percutaneous implantation techniques have gained popularity due to their favorable safety profile. Although in common use, biocompatibility of annuloplasty rings has been reported only sparsely in the literature, and none of these reports used the percutaneous technique of implantation. We report on the biocompatibility and the systemic safety of a novel transcatheter mitral valve annuloplasty ring (AMEND™) in 6 minipigs. This device is composed of a nitinol tube surrounded by a braided polyethylene terephthalate fabric tube. The device produced no adverse inflammatory response, showing gradual integration between the metal ring and the fabric by normal host fibrocellular response, leading to complete neoendocardium coverage. There was no evidence for adverse reactions, rejection, or intolerance in the valvular structure. In 2 animals, hemopericardium resulted from the implantation procedure, leading to right-sided cardiac insufficiency with pulmonary edema and liver congestion. The findings reported herein can serve as a case study for the expected healing pathology reactions after implantation of transcatheter mitral valve annuloplasty rings. © The Author(s) 2016.

Aim of study was to evaluate osseointegration of the KrF laser hydroxyapatite coated titanium alloy Ti6Al4V dental implants. For deposition KrF excimer laser in stainless- steel deposition chamber was used. Thickness of HA films were round 1 μm . Mini-pigs were used in this investigation. Implants were placed vertically into the lower jaw. After 14 weeks unloaded osseointegration the metal ceramic crowns were inserted. the experimental animals were sacrificed (1 year post insertion). The vertical position of implants was controlled with a radiograph. Microscopical sections were cut and ground. Sections were viewed using microscope with CCD camera. 1 year osseointegration in lower jaw confirmed by all implants presence of newly formed bone around the all implants. Laser-deposited coating the layer of fibrous connective tissue was seen only seldom. In the control group (titamium implant without cover) the fibrous connective tissue was seen between implant and newly formed bone.

The bone implant contact (BIC) has traditionally been evaluated with histological methods. Thereupon, strong correlations of two-dimensional (2D) BIC have been detected between μCT and destructive histology. However, due to the high intra-sample variability in BIC values, one histological slice is not sufficient to represent 3D BIC. Therefore, our aim has been to correlate the averaged values of 3-4 histological sections to 3D μCT. Fifty-four implants inserted into the maxilla of 14 minipigs were evaluated. Two different time points were selected to assess the 3D BIC (distance to implant: 2-5 voxels), an inner ring (6-30 voxels) and an outer ring (55-100 voxels) using μCT (voxel size: 10 μm) and to correlate the values to histomorphometry. Strong correlations (p implant, μCT values were higher compared with histomorphometry. Although 3-4 histological slices per implant seem to predict the 3D BIC, μCT might be advantageous because of its non-destructive 3D character. The healing time may not impact on the comparability. © 2017 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

Full Text Available Purpose. The aim of this animal study was the determination of accuracy of bone measurements in CBCT (cone-beam computed tomography in close proximity to titanium implants. Material and Methods. Titanium implants were inserted in eight Göttingen minipigs. 60 implants were evaluated histologically in ground section specimen and radiologically in CBCT in regard to thickness of the buccal bone. With random intercept models, the difference of histologic measurements and CBCT measurements of bone thickness was calculated. Results. The mean histological thickness of the buccal bone was 5.09 mm (CI 4.11–6.08 mm. The four raters measured slightly less bone in CBCT than it was found in histology. The random effect was not significant (p value 1.000. Therefore, the Intraclass Correlation Coefficient (ICC was 98.65% (CI 100.00–96.99%. Conclusion. CBCT is an accurate technique to measure even thin bone structures in the vicinity of titanium implants.

Spontaneous regression (SR) of human melanoma is a rare, well-documented phenomenon that is not still fully understood. Its detailed study cannot be performed in patients due to ethical reasons. Using the Melanoma-bearing Libechov Minipig (MeLiM) animals of various ages (from 3 weeks to 8 months) we implemented a long-term monitoring of melanoma growth and SR. We focused on immunohistochemical detection of two important extracellular matrix proteins, collagen IV and laminin, which are associated with cancer. We showed that SR of melanoma is a highly dynamic process. The expression of collagen IV and laminin correlated with changes in population of melanoma cells. Tumours of 3-week-old animals consisted primarily of melanoma cells with a granular expression of collagen IV and laminin around them. Thereafter, melanoma cells were gradually destroyed and tumour tissue was rebuilt into the connective tissue. Collagen IV expression slightly increased in tumours of 10-week-old pigs showing extracellular fibrous appearance. In tumours of older animals, areas lacking melanoma cells demonstrated a low expression and areas still containing melanoma cells a high expression of both proteins. We considered the age of 10 weeks as a turning point in the transition between tumour growth and SR of the MeLiM melanoma

The ability of Lactobacillus delbrueckii subsp. bulgaricus and Streptococcus thermophilus administered in yogurt to survive the passage through the upper gastrointestinal tract was investigated with Göttingen minipigs that were fitted with ileum T-cannulas. After ingestion of yogurt containing viable microorganisms, ileostomy samples were collected nearly every hour beginning 3 h after food uptake. Living L. delbrueckii subsp. bulgaricus and S. thermophilus were detected in the magnitude of 106 to 107 per gram of intestinal contents (wet weight) in all animals under investigation. A calculation of the minimum amount of surviving bacteria that had been administered is presented. Total DNA extracted from ileostomy samples was subjected to PCR, which was species specific for L. delbrueckii and S. thermophilus and subspecies specific for L. delbrueckii subsp. bulgaricus. All three bacterial groups could be detected by PCR after yogurt uptake but not after uptake of a semisynthetic diet. One pig apparently had developed an endogenous L. delbrueckii flora. When heat-treated yogurt was administered, L. delbrueckii was detected in all animals. S. thermophilus or L. delbrueckii subsp. bulgaricus was not detected, indicating that heat-inactivated cells and their DNAs had already been digested and their own L. delbrueckii flora had been stimulated for growth.

Two methods investigating learning and memory in juvenile Gottingen minipigs were evaluated for potential use in preclinical toxicity testing. Twelve minipigs were tested using a spatial hole-board discrimination test including a learning phase and two memory phases. Five minipigs were tested...... in a visual discrimination test. The juvenile minipigs were able to learn the spatial hole-board discrimination test and showed improved working and reference memory during the learning phase. Performance in the memory phases was affected by the retention intervals, but the minipigs were able to remember...... the concept of the test in both memory phases. Working memory and reference memory were significantly improved in the last trials of the memory phases. In the visual discrimination test, the minipigs learned to discriminate between the three figures presented to them within 9-14 sessions. For the memory test...

High-fat high-sucrose diet (HFHS) overfeeding is one of the main factors responsible for the increased prevalence of metabolic disorders. Elevated levels of branched-chain amino acids (BCAAs) have been associated with metabolic dysfunctions, including insulin resistance (IR). The aim of this study was to elucidate whether elevated BCAA levels are the cause or the consequence of IR and to determine the mechanisms and tissues involved in such a phenotype. We performed a 2-mo follow-up on minipigs overfed an HFHS diet and focused on kinetics fasting and postprandial (PP) BCAA levels and BCAA catabolism in key tissues. The study of the fasting BCAA elevation reveals that BCAA accumulation in the plasma compartment is well correlated with IR markers and body weight. Furthermore, the PP excursion of BCAA levels after the last HFHS meal was exacerbated when compared with that of the first meal, suggesting a reduced amino acid oxidation potential. Although only minor changes in BCAA metabolism were observed in liver, muscle, and the visceral adipose tissue, the oxidative deamination potential of the subcutaneous adipose tissue was blunted after 60 d of HFHS feeding. To our knowledge, the present results demonstrated for the first time in a swine model of obesity and IR, the existence of a phenotype related to high-circulating BCAA levels and metabolic dysregulation. The oxidative BCAA capacity reduction specifically in the subcutaneous adipose tissue emerges, at least in the present swine model, as the more plausible metabolic explanation for the elevated blood BCAA phenotype.

This study was performed with the objective of evaluating osseointegration of titanium alloy Ti6Al4V dental implants coated with hydroxylapatite (HA) deposited by a KrF laser. For this a KrF excimer laser and stainless-steel deposition chamber were used. The thickness of the HA films was approximately 1 micrometers . IN this investigation experimental animals minipigs were used; the implants were placed vertically into the lower jaw. After 14 weeks of unloaded osseointegration, metal-ceramic crowns were inserted and, at the same time, fluorescent solution was injected into the experimental animals. Six months after insertion of crowns the animals were sacrificed. The vertical position of the implants was checked by a radiograph. Microscopic sections were cut and ground, and the sections were examined under polarized and fluorescent light using a microscope with a charge coupled device camera. The six month long osseointegration in the lower jaw has confirmed the presence of newly formed bone around all the implants. In the experimental group, which had a laser-deposited coating, the layer of fibrous connective tissue was seen only randomly. In the control group (titanium implant without a cover) the fibrous connective tissue between the implant and the newly formed bone was observed more frequently, but this difference was not significant.

Chlamydia is one of the most common sexually transmitted diseases in humans worldwide, causing chronic lesions in the reproductive tract. Due to its often asymptomatic course, there is limited knowledge about the initial changes in the genital tract following infection. This study employs a novel sexually mature minipig model to investigate the initial histopathological changes following vaginal infection with Chlamydia trachomatis serovar D. A vaginal inoculation resulted in an infection primarily affecting the lower genital tract. The histopathological changes were characterized by a subepithelial inflammation consisting of neutrophils and mononuclear cells, followed by an increase in the number of plasma cells within the sub-epithelial stroma of the vagina. Detection of Chlamydia was associated with expression of cyclooxygenase-2 and interleukin-8 by superficial epithelial cells. The infection was self-limiting, with a duration of 7 days. Neutrophils, plasma cells and IL-8 have been linked with Chlamydia genital infection of unknown duration in human patients. In this study, we observe a similar pattern of local immune response/inflammation following experimental inoculation suggesting this porcine model shows promise as a model for translational chlamydia research.

Time-resolved contrast-enhanced MR angiography (4D-MRA), which allows the simultaneous visualization of the vasculature and blood-flow dynamics, is widely used in clinical routine. In this study, the impact of two different contrast agent injection methods on 4D-MRA was examined in a controlled, standardized setting in an animal model. Six anesthetized Goettingen minipigs underwent two identical 4D-MRA examinations at 1.5 T in a single session. The contrast agent (0.1 mmol/kg body weight gadobutrol, followed by 20 ml saline) was injected using either manual injection or an automated injection system. A quantitative comparison of vascular signal enhancement and quantitative renal perfusion analyses were performed. Analysis of signal enhancement revealed higher peak enhancements and shorter time to peak intervals for the automated injection. Significantly different bolus shapes were found: automated injection resulted in a compact first-pass bolus shape clearly separated from the recirculation while manual injection resulted in a disrupted first-pass bolus with two peaks. In the quantitative perfusion analyses, statistically significant differences in plasma flow values were found between the injection methods. The results of both qualitative and quantitative 4D-MRA depend on the contrast agent injection method, with automated injection providing more defined bolus shapes and more standardized examination protocols. • Automated and manual contrast agent injection result in different bolus shapes in 4D-MRA. • Manual injection results in an undefined and interrupted bolus with two peaks. • Automated injection provides more defined bolus shapes. • Automated injection can lead to more standardized examination protocols.

According to the coping styles hypothesis, an individual demonstrates an integrated behavioural and physiological response to environmental challenge that is consistent over time and across situations. Individual consistency in behavioural responses to challenge has been documented across the animal kingdom. Comparatively few studies, however, have examined inter-individual variation in the physiological response, namely glucocorticoid and catecholamine levels, the stress hormones secreted by the hypothalamic-pituitary-adrenal axis and the sympathetic nervous system, respectively. Variation in coping styles between individuals may be explained in part by differences in social rank and sex. Using 20 Yucatan minipigs (Sus scrofa) we: (1) investigated the existence of consistent inter-individual variation in exploratory behaviour and the hormonal stress response, and tested for correlations as predicted by the coping styles hypothesis; and (2) evaluated whether inter-individual behavioural and hormonal variation is related to social rank and sex. Salivary stress biomarkers (cortisol, alpha-amylase, chromogranin A) were assessed in the presence and absence of a stressor consisting of social isolation in a crate for 10 min. Principal components analysis on a set of behavioural variables revealed two traits, which we labelled exploratory tendency and neophobia. Neither exploratory tendency nor neophobia predicted the physiological stress response. Subordinate pigs exhibited higher catecholamine levels compared to dominant conspecifics. We observed sex differences in the repeatability of salivary stress markers and reactivity of the stress systems. The results do not provide support for the existence of behavioural-physiological coping styles in pigs. Sex is an important determinant of the physiological stress response and warrants consideration in research addressing behavioural and hormonal variation. Copyright © 2015 Elsevier Inc.

Full Text Available Animal models of familial juvenile onset of Alzheimer's disease (AD often fail to produce diverse pathological features of the disease by modification of single gene mutations that are responsible for the disease. They can hence be poor models for testing and development of novel drugs. Here, we analyze in vitro-produced stem cells and their derivatives from a large mammalian model of the disease created by overexpression of a single mutant human gene (APPsw. We produced hemizygous and homozygous radial glial-like cells following culture and differentiation of embryonic stem cells (ESCs isolated from embryos obtained from mated hemizygous minipigs. These cells were confirmed to co-express varying neural markers, including NES, GFAP and BLBP, typical of type one radial glial cells (RGs from the subgranular zone. These cells had altered expression of CCND1 and NOTCH1 and decreased expression of several ribosomal RNA genes. We found that these cells were able to differentiate into astrocytes upon directed differentiation. The astrocytes produced had decreased α- and β-secretase activity, increased γ-secretase activity and altered splicing of tau. This indicates novel aspects of early onset mechanisms related to cell renewal and function in familial AD astrocytes. These outcomes also highlight that radial glia could be a potentially useful population of cells for drug discovery, and that altered APP expression and altered tau phosphorylation can be detected in an in vitro model of the disease. Finally, it might be possible to use large mammal models to model familial AD by insertion of only a single mutation.

Effects of coconut oil on glycemia, inflammation, and urogenital microbial parameters in female Ossabaw mini-pigs.

Full Text Available Forty percent of American women are obese and at risk for type II diabetes, impaired immune function, and altered microbiome diversity, thus impacting overall health. We investigated whether obesity induced by an excess calorie, high fat diet containing hydrogenated fats, fructose, and coconut oil (HFD altered glucose homeostasis, peripheral immunity, and urogenital microbial dynamics. We hypothesized that HFD would cause hyperglycemia, increase peripheral inflammation, and alter urogenital microbiota to favor bacterial taxonomy associated with inflammation. We utilized female Ossabaw mini-pigs to model a 'thrifty' metabolic phenotype associated with increased white adipose tissue mass. Pigs were fed HFD (~4570 kcal/pig/day or lean (~2000 kcal/pig/day diet for a total of 9 estrous cycles (~6 months. To determine the effect of cycle stage on cytokines and the microbiome, animals had samples collected during cycles 7 and 9 on certain days of the cycle: D1, 4, 8, 12, 16, 18. Vaginal swabs or cervical flushes assessed urogenital microbiota. Systemic fatty acids, insulin, glucose, and cytokines were analyzed. Pig weights and morphometric measurements were taken weekly. Obese pigs had increased body weight, length, heart and belly girth but similar glucose concentrations. Obese pigs had decreased cytokine levels (IL-1β, TNF-α, IL-4, IL-10, arachidonic acid and plasma insulin, but increased levels of vaccenic acid. Obese pigs had greater urogenital bacterial diversity, including several taxa known for anti-inflammatory properties. Overall, induction of obesity did not induce inflammation but shifted the microbial communities within the urogenital tract to an anti-inflammatory phenotype. We postulate that the coconut oil in the HFD oil may have supported normal glucose homeostasis and modulated the immune response, possibly through regulation of microbial community dynamics and fatty acid metabolism. This animal model holds promise for the study of

Full Text Available The Göttingen Minipig (GM is used as large animal model in articular cartilage research. The aim of the study was to introduce osteoarthritis (OA in the GM by resecting the anterior cruciate ligament (ACLR according to Pond and Nuki, verified by histological and magnetic resonance imaging (MRI scoring as well as analysis of gene and protein expression.The eight included skeletally mature female GM were assessed after ACLR in the left and a sham operation in the right knee, which served as control. 26 weeks after surgery the knee joints were scanned using a 3-Tesla high-field MR tomography unit with a 3 T CP Large Flex Coil. Standard proton-density weighted fat saturated sequences in coronal and sagittal direction with a slice thickness of 3 mm were used. The MRI scans were assessed by two radiologists according to a modified WORMS-score, the X-rays of the knee joints by two evaluators. Osteochondral plugs with a diameter of 4mm were taken for histological examination from either the main loading zone or the macroscopic most degenerated parts of the tibia plateau or condyle respectively. The histological sections were blinded and scored by three experts according to Little et al. Gene expression analysis was performed from surrounding cartilage. Expression of adamts4, adamts5, acan, col1A1, col2, il-1ß, mmp1, mmp3, mmp13, vegf was determined by qRT-PCR. Immunohistochemical staining (IH of Col I and II was performed. IH was scored using a 4 point grading (0-no staining; 3-intense staining.Similar signs of OA were evident both in ACLR and sham operated knee joints with the histological scoring result of the ACLR joints with 6.48 ± 5.67 points and the sham joints with 6.86 ± 5.84 points (p = 0.7953 The MRI scoring yielded 0.34 ± 0.89 points for the ACLR and 0.03 ± 0.17 for the sham knee joints.

Cytochromes P450 2E1 of human and minipig origin were examined by absorption spectroscopy under high hydrostatic pressure and by resonance Raman spectroscopy. Human enzyme tends to denature to the P420 form more easily than the minipig form; moreover, the apparent compressibility of the heme active site (as judged from a redshift of the absorption maximum with pressure) is greater than that of the minipig counterpart. Relative compactness of the minipig enzyme is also seen in the Raman spectra, where the presence of planar heme conformation was inferred from band positions characteristic of the low-spin heme with high degree of symmetry. In this respect, the CYP2E1 seems to be another example of P450 conformational heterogeneity as shown, e.g., by Davydov et al. for CYP3A4 [Biochem. Biophys. Res. Commun. 312 (2003) 121-130]. The results indicate that the flexibility of the CYP active site is likely one of its basic structural characteristics

The in vitro differentiation and immunosuppressive capacity of mesenchymal stem cells (MSCs) derived from synovial fluid (SF-MSCs) and bone marrow extract (BM-MSCs) in an isogenic background of minipigs were comparatively analyzed in a collagen-induced arthritis (CIA) mouse model of rheumatoid arthritis (RA). The proliferation capacity and expression of pluripotent transcription factors (Oct3/4 and Sox2) were significantly (P<0.05) higher in SF-MSCs than in BM-MSCs. The differentiation capacity of SF-MSCs into adipocytes, osteocytes and neurocytes was significantly (P<0.05) lower than that of BM-MSCs, and the differentiation capacity of SF-MSCs into chondrocytes was significantly (P<0.05) higher than that of BM-MSCs. Systemic injection of BM- and SF-MSCs significantly (P<0.05) ameliorated the clinical symptoms of CIA mice, with SF-MSCs having significantly (P<0.05) higher clinical and histopathological recovery scores than BM-MSCs. Furthermore, the immunosuppressive properties of SF-MSCs in CIA mice were associated with increased levels of the anti-inflammatory cytokine interleukin (IL)-10, and decreased levels of the pro-inflammatory cytokine IL-1β and osteoclast-related sRANKL. In conclusion, SF-MSCs exhibited eminent pluripotency and differentiation capacity into chondrocytes, addition to substantial in vivo immunosuppressive capacity by elevating IL-10 and reducing IL-1β levels in CIA mice. - Highlights: • Immunosuppressive capacity of BM-, SM-, and SF-MSCs was evaluated in an RA model. • Proliferation, pluripotency and chondrogenic differentiation capacity were higher in SF-MSCs. • SF-MSCs exhibited improved therapeutic effects than BM-MSCs. • SF-MSCs may have applications as immunosuppressive therapy in autoimmune diseases.

Effects of Chronic Consumption of Sugar-Enriched Diets on Brain Metabolism and Insulin Sensitivity in Adult Yucatan Minipigs.

Directory of Open Access Journals (Sweden)

Melissa Ochoa

Full Text Available Excessive sugar intake might increase the risk to develop eating disorders via an altered reward circuitry, but it remains unknown whether different sugar sources induce different neural effects and whether these effects are dependent from body weight. Therefore, we compared the effects of three high-fat and isocaloric diets varying only in their carbohydrate sources on brain activity of reward-related regions, and assessed whether brain activity is dependent on insulin sensitivity. Twenty-four minipigs underwent 18FDG PET brain imaging following 7-month intake of high-fat diets of which 20% in dry matter weight (36.3% of metabolisable energy was provided by starch, glucose or fructose (n = 8 per diet. Animals were then subjected to a euglycemic hyperinsulinemic clamp to determine peripheral insulin sensitivity. After a 7-month diet treatment, all groups had substantial increases in body weight (from 36.02±0.85 to 63.33±0.81 kg; P<0.0001, regardless of the diet. All groups presented similar insulin sensitivity index (ISI = 1.39±0.10 mL·min-1·μUI·kg. Compared to starch, chronic exposure to fructose and glucose induced bilateral brain activations, i.e. increased basal cerebral glucose metabolism, in several reward-related brain regions including the anterior and dorsolateral prefrontal cortex, the orbitofrontal cortex, the anterior cingulate cortex, the caudate and putamen. The lack of differences in insulin sensitivity index and body weight suggests that the observed differences in basal brain glucose metabolism are not related to differences in peripheral insulin sensitivity and weight gain. The differences in basal brain metabolism in reward-related brain areas suggest the onset of cerebral functional alterations induced by chronic consumption of dietary sugars. Further studies should explore the underlying mechanisms, such as the availability of intestinal and brain sugar transporter, or the appearance of addictive-like behavioral

To evaluate the safety and the technical feasibility of the use of an endobronchial occlusion stent and to get preliminary data for the development of the optimal material required for endobronchial occlusions. A commercialized, self-expandable tracheobronchial stent was modified; one half had a polyurethane cover with an occluded end and the other half was uncovered with a flaring configuration. The occluded end was placed such that it would face the distal lung. Under fluoroscopic guidance, seven stents were placed at the lower lobar bronchus in 6 mini-pigs. The bronchial obstruction was examined immediately after stent placement. Chest radiographs were taken at days 1, 7, 14, and 28 after stent placement and the removed airways from two, two, one, and one mini-pigs sacrificed on corresponding days were examined for the maintenance of bronchial obstruction. Stents were successfully placed and induced the immediate bronchial obstruction in all mini-pigs. Five of seven airways with occlusion stents maintained an obstruction until the mini-pigs were sacrificed. Proximal stent migration occurred in two mini-pigs (29%), and pulmonary consolidations were observed distal to four of the stents (57%). The placement of an endobronchial occlusion stent and the obstruction of targeted bronchi seem to be feasible, but an add-on check valve should be considered to prevent stent migration and obstructive pneumonia

Radium-224 (Ra-224) was already used as medicament before world war I; but because of serious side effects soon abandoned. It was revived as a remedy for tuberculosis and ankylosing spondylitis after world war II by a country doctor called Troch, supported by the Insurance Company ''Braunschweiger Landesversicherungsanstalt'' and over enthusiastic press reports. The 'new' medicine called 'Peteosthor' was a mixture of Ra-224 with traces of the red dye cosine and platinsol. The propaganda in favour of this therapy was so strong, that the government of Lower Saxony asked the University of Goettingen and others to examine this new 'wonderdrug'. Dr. Troch demanded that it should be used only under his personal supervision. As youngest assistent at the university childrens hospital of the University Goettingen I was sent in 1948 to this hospital in Hildesheim to examine 'Peteosthor'. (orig.)

The copper(II) complex of ethylglyoxal bis(thiosemicarbazone) (Cu-ETS) was evaluated as a positron emission tomography (PET) radiopharmaceutical for assessment of regional renal perfusion. Methods: The concordance of renal flow estimates obtained with 11- and 15-μm microspheres was confirmed in four immature farm pigs using co-injected 46 Sc- and 57 Co-microspheres administered into the left ventricle. With the use of both immature farm pigs (n=3) and mature Goettingen minipigs (n=6), regional renal radiocopper uptake following intravenous [ 64 Cu]Cu-ETS administration was compared to microsphere measurements of renal perfusion. The distribution and kinetics of [ 64 Cu]Cu-ETS were further studied by PET imaging of the kidneys. The rate of [ 64 Cu]Cu-ETS decomposition by blood was evaluated in vitro, employing octanol extraction to recover intact [ 64 Cu]Cu-ETS. Results: The co-injected 11- and 15-μm microspheres provided similar estimates of renal flow. A linear relationship was observed between the renal uptake of intravenous [ 64 Cu]Cu-ETS and regional renal perfusion measured using microspheres. [ 64 Cu]Cu-ETS provided high-quality PET kidney images demonstrating the expected count gradient from high-flow outer cortex to low-flow medulla. When incubated with pig blood in vitro at 37 o C, the [ 64 Cu]Cu-ETS radiopharmaceutical was observed to decompose with a half-time of 2.8 min. Conclusion: Cu-ETS appears suitable for use as a PET radiopharmaceutical for evaluation of regional renal perfusion, affording renal uptake of radiocopper that varies linearly with microsphere perfusion measurements. Quantification of renal perfusion (in ml min -1 g -1 ) with [ 60,61,62,64 Cu]Cu-ETS will require correcting the arterial input function for the fraction of blood radiocopper remaining present as the intact Cu-ETS radiopharmaceutical, since the Cu-ETS chelate has limited chemical stability in blood. Rapid octanol extraction of blood samples appears suitable as an approach

Consideration of the Development of the Gastrointestinal Tract in the Choice of Species for Regulatory Juvenile Studies.

Science.gov (United States)

Downes, Noel John

2018-01-15

Although the rat is close to being the automatic choice for regulatory juvenile toxicity studies, there are several shortcomings in this model. Choosing a species should take into serious consideration the importance of gastrointestinal tract development in the period before weaning as this may have a major effect on exposure. A comparison of the anatomical changes in the stomach and small intestine of mini-pig and rat show that the mini-pig is a far closer model for man than is the rat, although there are a few unusual aspects of small intestinal development in the mini-pig. Considerations of the development of the gastrointestinal tract and choice of species have the potential to affect safety assessment and should be a prime consideration when planning an investigation.

Abstract Introduction: Cannabidiol (CBD) can convert to Δ9-tetrahydrocannabinol (THC) in vitro with prolonged exposure to simulated gastric fluid; however, in vitro conditions may not be representative of the in vivo gut environment. Using the minipig, we investigated whether enteral CBD converts to THC in vivo. Materials and Methods: Synthetic CBD (100 mg/mL) was administered orally in a sesame oil formulation twice daily to minipigs (N=3) in 15 mg/kg doses for 5 consecutive days. Blood samp...

Noor eesti teater ja Noor-Eesti. Young Estonian Theatre and Young Estonia

Full Text Available This article begins by examining points of intersection between two professional theatres, ”Estonia” and ”Vanemuine” (both established in 1906, their young directors – Karl Menning, Paul Pinna, Theodor Altermann, and Karl Jungholz, and the literary movement Young Estonia. Subsequently, we will consider Young Estonia’s theatrical ideals and the influence of these ideas on later Estonian theatrical life. Since not much information has survived regarding direct personal contacts between ”movers and shakers” in the theatre world and Young Estonians, the main focus here shall be on indirect creative connections and influences. One such context is education: like the Young Estonians, theatre activists of the younger generation aspired to place themselves on the larger map of European culture. Thus, their artistic beliefs and goals shall be examined in relation to those of Young Estonians’ quest for modern culture. Pinna, Altermann, Menning, Jungholz, and others went on study tours to Germany and France, where they were energized and inspired by innovative German and Russian theatres, by naturalistic staging, and by psychological realism, both in acting and in performance style. Among their models were A. Antoine’s Théâtre- Libre in Paris, K. Stanislavski’s Art Theatre in Moscow, O. Brahm’s Lessing-Theater, and M. Reinhardt’s Deutsches Theater in Berlin. These models were likewise known to the Young Estonians, but if theatre activists oriented themselves more fundamentally to German naturalist and realist dramatic art, Young Estonians were more taken with ”theatrical theatre” with its symbolist and impressionist influences. The Young Estonians attended performances at both theatres, ”Vanemuine” and ”Estonia”, and wrote numerous theatre reviews. Yet in the Young Estonia albums (yearbooks and in the magazine Young Estonia, theatre topics have a relatively modest representation. Young Estonians did not have direct

Development of immune organs and functioning in humans and test animals: Implications for immune intervention studies.

A healthy immune status is mostly determined during early life stages and many immune-related diseases may find their origin in utero and the first years of life. Therefore, immune health optimization may be most effective during early life. This review is an inventory of immune organ maturation events in relation to developmental timeframes in minipig, rat, mouse and human. It is concluded that time windows of immune organ development in rodents can be translated to human, but minipig reflects the human timeframes better; however the lack of prenatal maternal-fetal immune interaction in minipig may cause less responsiveness to prenatal intervention. It is too early to conclude which immune parameters are most appropriate, because there are not enough comparative immune parameters. Filling these gaps will increase the predictability of results observed in experimental animals, and guide future intervention studies by assessing relevant parameters in the right corresponding developmental time frames.

ABSTRACT Psoriasis is a complex human-specific disease characterized by perturbed keratinocyte proliferation and a pro-inflammatory environment in the skin. Porcine skin architecture and immunity are very similar to that in humans, rendering the pig a suitable animal model for studying the biology and treatment of psoriasis. Expression of integrins, which is normally confined to the basal layer of the epidermis, is maintained in suprabasal keratinocytes in psoriatic skin, modulating proliferation and differentiation as well as leukocyte infiltration. Here, we generated minipigs co-expressing integrins α2 and β1 in suprabasal epidermal layers. Integrin-transgenic minipigs born into the project displayed skin phenotypes that correlated with the number of inserted transgenes. Molecular analyses were in good concordance with histological observations of psoriatic hallmarks, including hypogranulosis and T-lymphocyte infiltration. These findings mark the first creation of minipigs with a psoriasiform phenotype resembling human psoriasis and demonstrate that integrin signaling plays a key role in psoriasis pathology.

We study the multiplicities of Young modules as direct summands of permutation modules on cosets of Young subgroups. Such multiplicities have become known as the p-Kostka numbers. We classify the indecomposable Young permutation modules, and, applying the Brauer construction for p-permutation modules, we give some new reductions for p-Kostka numbers. In particular we prove that p-Kostka numbers are preserved under multiplying partitions by p, and strengthen a known reduction given by Henke, c...

Transcriptome analysis on the inflammatory cell infiltration of nonalcoholic steatohepatitis in bama minipigs induced by a long-term high-fat, high-sucrose diet.

Directory of Open Access Journals (Sweden)

Full Text Available Long-term adherence to a high-fat, high-calorie diet influences human health and causes obesity, metabolic syndrome and nonalcoholic steatohepatitis (NASH. Inflammation plays a key role in the development of NASH; however, the mechanism of inflammation induced by over-nutrition remains largely unknown. In this study, we fed Bama minipigs a high-fat, high-sucrose diet (HFHSD for 23 months. The pigs exhibited characteristics of metabolic syndrome and developed steatohepatitis with greatly increased numbers of inflammatory cells, such as lymphocytes (2.27-fold, P<0.05, Kupffer cells (2.59-fold, P<0.05, eosinophils (1.42-fold, P<0.05 and neutrophils (2.77-fold, P<0.05. High-throughput RNA sequencing (RNA-seq was performed to explore the systemic transcriptome of the pig liver during inflammation. Approximately 18.2 gigabases of raw sequence data were generated, and over 303 million high-quality reads were assembled into 21,126 unigenes. RNA-seq data analysis showed that 822 genes were differentially expressed in liver (P<0.05 between the HFHSD and control groups. Kyoto Encyclopedia of Genes and Genomes (KEGG analysis showed that the process of inflammation involved the inflammatory signal transduction-related toll-like receptor, MAPK, and PPAR signaling pathways; the cytokine-related chemokine signaling, cytokine-cytokine receptor interaction, and IL2, IL4, IL6, and IL12 signaling pathways; the leukocyte receptor signaling-related T cell, B cell, and natural killer cell signaling pathways; inflammatory cell migration and invasion- related pathways; and other pathways. Moreover, we identified several differentially expressed inflammation-related genes between the two groups, including FOS, JUN, TLR7, MYC, PIK3CD, VAV3, IL2RB and IL4R, that could be potential targets for further investigation. Our study suggested that long-term HFHSD induced obesity and liver inflammation, providing basic insight into the molecular mechanism of this condition and

Research conducted with a group of young skaters in a public track skating in the city of Porto Alegre - RS. In a total nine months of direct observation, each reported in Field Diaries. We seek to understand how the leisure of young people who gave the practice of skateboarding, was related to other aspects of their daily lives. After completing the work, we consider that - to remain in practice the skateboard - young people needed to reconcile the charges of their families, in addition to labels and stereotypes imposed from "outside" the universe of practitioners of this sport. We noticed also that young people go through all this in order to keep their "projects" on the skateboard.

Coil is a very important magnet component. The turn location and the coil size impact both mechanical and magnetic behavior of the magnet. The Young's modulus plays a significant role in determining the coil location and size. Therefore, Young's modulus study is essential in predicting both the analytical and practical magnet behavior. To determine the coil Young's modulus, an experiment has been conducted to measure azimuthal sizes of a half quadrant QSE101 inner coil under different loading. All measurements are made at four different positions along an 8-inch long inner coil. Each measurement is repeated three times to determine the reproducibility of the experiment. To ensure the reliability of this experiment, the same measurement is performed twice with a open-quotes dummy coil,close quotes which is made of G10 and has the same dimension and similar azimuthal Young's modulus as the inner coil. The difference between the G10 azimuthal Young's modulus calculated from the experiments and its known value from the manufacturer will be compared. Much effort has been extended in analyzing the experimental data to obtain a more reliable Young's modulus. Analysis methods include the error analysis method and the least square method

We present a spectroscopic and kinematic analysis of 79 nearby M dwarfs in 77 systems. All of these dwarfs are low-proper-motion southern hemisphere objects and were identified in a nearby star survey with a demonstrated sensitivity to young stars. Using low-resolution optical spectroscopy from the Red Side Spectrograph on the South African Large Telescope, we have determined radial velocities, H-alpha, lithium 6708 Å, and potassium 7699 Å equivalent widths linked to age and activity, and spectral types for all of our targets. Combined with astrometric information from literature sources, we identify 44 young stars. Eighteen are previously known members of moving groups within 100 pc of the Sun. Twelve are new members, including one member of the TW Hydra moving group, one member of the 32 Orionis moving group, 9 members of Tucana-Horologium, one member of Argus, and two new members of AB Doradus. We also find 14 young star systems that are not members of any known groups. The remaining 33 star systems do not appear to be young. This appears to be evidence of a new population of nearby young stars not related to the known nearby young moving groups.

This report is the second part of the previously published study on the impact of light/chemical hardening technology and a newly formulated composite graft material for crestal augmentation during immediate implant placement. A total of 48 implants were placed into the sockets of the mesial roots of freshly extracted mandibular premolar teeth in three minipigs. Crestal areas and intrabony spaces were randomly augmented with light-hardened graft materials including a composite graft consisting of polymethylmethacrylate, polyhydroxylethylmethacrylate, and calcium hydroxide (PPCH) plus polyanhydride (PA); PPCH graft; and PA graft, or left untreated. Distal sockets not receiving implants and the sockets of first molars (n = 60) were randomly treated with one of the graft materials or left empty. In addition, two molar sockets were treated with the original PPCH graft material. Quantitative microcomputed tomography (micro-CT) was used to assess alveolar bone structure and tissue compositions. Histologic evaluations included descriptive histology to assess the peri-implant wound healing, as well as histomorphometric measurements to determine bone-to-implant contact (BIC). Both trabecular and cortical bone measurements by micro-CT did not reveal any significant differences among the groups. Sites augmented with PPCH+PA resulted in significantly greater BIC surface than PPCH alone and no-graft-treated implants (P sockets with an intact crestal cortical bone. Histologic evaluations supported the previous findings on implant stability and function and confirmed that PPCH+PA provides a greater BIC with a well-organized implant-bone interface and is useful in crestal augmentation during immediate implant placement.

Albert Mrgole

1997-01-01

Full Text Available The increasing number of young people participating in adult education programmes has, in the recent years, raised the question of transfer from regular education system to labour market where a large proportion of young people remain socially marginalized and isolated. Young people in adult education are a special target group; in order to plan educational programmes properly, we need to be familiar with their specific characteristics. The article, on the level of a statistical data outline and its paradoxes, introduces the category of young people in adult education as an impact of system factors, and defines related problems in the register, which - for more thorough understanding - dictates sociologically and anthropologically directed analytical approach. The first effect of this, not solely pedagogical view, is presented in the second part of the article, where Mrgole proposes an analysis of educational needs definition and its dangerous consequences in original planning of educational programmes. The concluding part takes a wider perspective and treats the factors of early school-leaving of young people, taking into consideration direct experience in experimental educational programmes for the young. The article ends with an outline of basic elements which the planners of andragogical educational programmes intended for young people should consider in their planning to achieve effective curricula.

Porcine foetal and neonatal CYP3A liver expression

Directory of Open Access Journals (Sweden)

Marie Louise Hiort Hermann

2011-05-01

Full Text Available Human cytochrome P450 3A7 (CYP3A7 and cytochrome P450 3A4 (CYP3A4 are hepatic metabolising enzymes which participates in the biotransformation of endo- and exogenous substances in foetuses and neonates respectively. These CYP3A enzymes display an inverse relationship: CYP3A7 is the dominant enzyme in the foetal liver, whereas the expression of CYP3A4 is low. After parturition there is a shift in the expression, thus CYP3A7 is down regulated, while the level of CYP3A4 gradually increases and becomes the dominant metabolising CYP3A enzyme in the adult. The minipig is increasingly being used as a model for humans in biomedical studies, because of its many similarities with the human physiology and anatomy. The aim of this study was to examine whether, as in humans, a shift is seen in the hepatic expression of a CYP3A7- like enzyme to cytochrome P450 3A29 (CYP3A29 (an orthologue to the human CYP3A4 in minipigs. This was elucidated by examining the hepatic mRNA expression of CYP3A7 and CYP3A29 in 39 foetuses and newborn Göttingen minipigs using quantitative real time polymerase chain reaction (qPCR. Furthermore the immunochemical level of CYP3A7-LE and CYP3A29 was measured in liver microsomes using western blotting. The expression of CYP3A29 was approximately 9- fold greater in neonates compared to foetuses, and a similar difference was reflected on the immunochemical level. It was not possible to detect a significant level of foetal CYP3A7 mRNA, but immunoblotting showed a visible difference depending on age. This study demonstrates an increase in the expression of CYP3A29, the CYP3A4 orthologue in perinatal minipigs as in humans, which suggests that the minipig could be a good model when testing for human foetal toxicity towards CYP3A4 substrates.

YOUNG INVESTIGATOR SPECIAL ISSUE (Editorial

2004-11-01

Full Text Available Welcome to the first Young Investigator Special Issue of the Journal of Sports Science and Medicine (JSSM. The JSSM family is proud to start this new service to the Sport Science community and to young researchers. The background in starting this issue was the observation that large amounts of high-quality research is conducted every year by students and young investigators, but often remains solely in local university libraries and never reaches the scientific community or databases. In addition, most international journals have a high threshold in accepting papers, and it is often hard to reach this level for junior scientists because of lack of experience, supervision or confidence. These are major reasons that delay or in some cases stop young researchers from publishing their valuable work. We all received help from senior colleagues in the beginning of our career. Now it is our turn to help youngsters. With this special issue, the JSSM is now serving young researchers as a channel for publishing their work. Our goal is to motivate young researchers to submit their work to JSSM, but we also aim to motivate supervisors and expert referees to be supportive and constructive towards these young scientists at the very beginning of their career. The Young Investigator Special Issue followed a normal peer-review process, except that there were no straight rejections in the first phase of review. We advised the reviewers of the Young Investigator Special Issue to proceed with constructive advice and remarks for all manuscripts. This offered a great opportunity for the Young Investigators to revise the manuscript, while at the same time contributing to the learning process. Thereafter, if the revisions were properly conducted according to the remarks from reviewers, the manuscripts were accepted for publication. We have received many manuscripts from young researchers with a lot of potential. There has been plenty of evidence of great talent

Irreducible Specht modules are signed Young modules

OpenAIRE

Hemmer, David J.

2005-01-01

Recently Donkin defined signed Young modules as a simultaneous generalization of Young and twisted Young modules for the symmetric group. We show that in odd characteristic, if a Specht module $S^\\lambda$ is irreducible, then $S^\\lambda$ is a signed Young module. Thus the set of irreducible Specht modules coincides with the set of irreducible signed Young modules. This provides evidence for our conjecture that the signed Young modules are precisely the class of indecomposable self-dual module...

2014-01-01

This is a thorough investigation into contemporary young people and their media life. The article conceptualizes a typology of media life, drawing on a theoretical body involving the sociology of generations, life course research, media life and individualization. This empirically derived typology...... makes a strong instrument for an understanding of the media life of the young, furnishing insights into how they have constructed their use of media. The investigation is based on a robust national survey with Swedes born 1994–2001, conducted in 2010, and focusing on four media: television, gaming......, the Internet and mobile devices. Two of the findings are particularly surprising. Firstly, the results reveal that the young generally lead heterogeneous media lives, varying with age and sex. Secondly, although some young people literarily live their life in media, there are also de facto young who live...

Complex young lives: a collective qualitative case study analysis of young fatherhood and breastfeeding.

Science.gov (United States)

Ayton, Jennifer; Hansen, Emily

2016-01-01

Of all births in Australia, 10 % are to young fathers aged less than 24 years. How young fathers experience any breastfeeding and how this is shaped by their social context is poorly understood. Our aim is to increase understanding of the lived experience of young fathers (aged less than 24 years) and to explore the way they speak about breastfeeding in the context of their lives and parenting. This collective case study analysis uses qualitative data from interviews and focus groups with young fathers (aged less than 24 years) and community support staff. The research was undertaken in Tasmania, Australia, March to December 2013. Young fathers in our study had complex social and emotional circumstances that meant breastfeeding was not a high priority despite them valuing the health benefits of breastfeeding for their babies. If supported by peers and their community they appear to have a more positive parenting experience. Breastfeeding although understood by the young fathers in our study as healthy and desirable is not a priority in their lives. Learning to be a parent and support their partners to breastfeed may be more effectively gained through mentoring and father-to-father localized community based support services.

The copper(II) complex of ethylglyoxal bis(thiosemicarbazone) (Cu-ETS) was evaluated as a positron emission tomography (PET) radiopharmaceutical for assessment of regional renal perfusion. Methods: The concordance of renal flow estimates obtained with 11- and 15-{mu}m microspheres was confirmed in four immature farm pigs using co-injected {sup 46}Sc- and {sup 57}Co-microspheres administered into the left ventricle. With the use of both immature farm pigs (n=3) and mature Goettingen minipigs (n=6), regional renal radiocopper uptake following intravenous [{sup 64}Cu]Cu-ETS administration was compared to microsphere measurements of renal perfusion. The distribution and kinetics of [{sup 64}Cu]Cu-ETS were further studied by PET imaging of the kidneys. The rate of [{sup 64}Cu]Cu-ETS decomposition by blood was evaluated in vitro, employing octanol extraction to recover intact [{sup 64}Cu]Cu-ETS. Results: The co-injected 11- and 15-{mu}m microspheres provided similar estimates of renal flow. A linear relationship was observed between the renal uptake of intravenous [{sup 64}Cu]Cu-ETS and regional renal perfusion measured using microspheres. [{sup 64}Cu]Cu-ETS provided high-quality PET kidney images demonstrating the expected count gradient from high-flow outer cortex to low-flow medulla. When incubated with pig blood in vitro at 37{sup o}C, the [{sup 64}Cu]Cu-ETS radiopharmaceutical was observed to decompose with a half-time of 2.8 min. Conclusion: Cu-ETS appears suitable for use as a PET radiopharmaceutical for evaluation of regional renal perfusion, affording renal uptake of radiocopper that varies linearly with microsphere perfusion measurements. Quantification of renal perfusion (in ml min{sup -1} g{sup -1}) with [{sup 60,61,62,64}Cu]Cu-ETS will require correcting the arterial input function for the fraction of blood radiocopper remaining present as the intact Cu-ETS radiopharmaceutical, since the Cu-ETS chelate has limited chemical stability in blood.

ROMANIAN YOUNG ENTREPRENEURS FEATURES: AN EMPIRICAL SURVEY

Directory of Open Access Journals (Sweden)

Ceptureanu Sebastian Ion

2015-07-01

Full Text Available There are many studies linking entrepreneurship and economic development. For specialists and public decision makers, developing entrepreneurship seems to be an easy policy action, even though actions and results are rather debatable. Unfortunately the relevant literature is not so generous concerning youth entrepreneurship. Youth is one of the most vulnerable groups in society, especially in the current economic and demographic situation in European Union and worldwide. At the same time, youth is the period when most people engage in their first job, are gaining financial independence and are assuming new responsibilities and roles shaping their identity. With respect to this, starting their own business is a natural choice for many young people. When considering entrepreneurial potential of young Romanians, there is almost not any data available. This paper aims to disseminate the results of a survey focused on young entrepreneurs, designed to fill the gap in the literature about Romanian young entrepreneurs’ features. The empirical study was divided in five parts: A. Personality of young entrepreneurs, highlighting the main features of behaviour and personality of young entrepreneurs. B. Professional background, focusing on young entrepreneurs’ background and how it influences their interest and performance improvement. C. Risk and crisis acceptance, highlighting the ability of young entrepreneurs to deal with critical situations. D. Business and business environment, focusing on internal and environmental aspects of the business. E. Social - cultural attitude, highlighting the attitude of society (incentives and disincentives to entrepreneurial initiatives of young people. This are excerpts of results from the first part, regarding personality of Romanian young entrepreneurs, concerning issues like level of independence, capacity for innovation, self-confidence, decision making process, level of persistence flexibility of young

LMC clusters: young

International Nuclear Information System (INIS)

Freeman, K.C.

1980-01-01

The young globular clusters of the LMC have ages of 10 7 -10 8 y. Their masses and structure are similar to those of the smaller galactic globular clusters. Their stellar mass functions (in the mass range 6 solar masses to 1.2 solar masses) vary greatly from cluster to cluster, although the clusters are similar in total mass, age, structure and chemical composition. It would be very interesting to know why these clusters are forming now in the LMC and not in the Galaxy. The author considers the 'young globular' or 'blue populous' clusters of the LMC. The ages of these objects are 10 7 to 10 8 y, and their masses are 10 4 to 10 5 solar masses, so they are populous enough to be really useful for studying the evolution of massive stars. The author concentrates on the structure and stellar content of these young clusters. (Auth.)

Abraham, S F; Mira, M; Beumont, P J; Sowerbutts, T D; Llewellyn-Jones, D

1983-09-03

Disordered eating and weight-control behaviour is becoming increasingly common among adolescent girls. We studied four groups of young women aged between 15 and 27 years (106 school and university students, 50 ballet school students, 22 patients suffering from anorexia nervosa and 44 patients with bulimia). Our results suggest that most young women diet at some time and lose more than three kg in weight; that they may experience episodes of binge eating and "picking" behaviour; and that they wish to be thinner irrespective of their current body weight. Twenty per cent of young women may fulfil the criteria for an eating disorder (bulimia or anorexia nervosa) at some stage, however briefly, and about 7% abuse laxatives or diuretics in order to achieve a fashionably slim figure. We suggest that most young women may pass through a phase of what is currently called disordered eating, and that this is part of normal development and may not necessarily require treatment. The incidence of disordered eating is greater in those young women who are under pressure to maintain a low body weight.

This dissertation started off with the observation that attention for news among young people decreases. More precisely, previous survey studies outlined a triple shift in the current young generation’s use of news: from more to less news, from offline to online news, and from professional to non-professional news sources. Underlying these three trends, was the finding that news does not constitute a substantial part of the daily routines of young people. This finding is disturbing given news...

Full Text Available Violence against women in relationships young people has become in recent years a public health problem of major social. This article, with a view to the prevention, seeks to address the psychological characteristics of the perpetrator of pair in young relations. An initial review of the personality features investigated in previous studies and their influence on violent behaviour was carried out. Following this, an empirical study on a sample of young people was performed. Methods: We conducted a study with 100 young people of Valencia. Of these, 50 are young offenders and 50 couple, young students of compulsory secondary education. Data are obtained and analyzed psychological characteristics differences between groups. Results: The study conducted shows that in general, young offenders have one hand high scores on neuroticism, impulsivity, external locus of control, psychoticism and antisocial behavior. Furthermore show low scores on self-control, empathy, selfesteem and frustration tolerance. Conclusions: The results of this paper make it abundantly clear that violence in young relationships is important enough to be considered from different sectors of society and justifies the need to develop and implement prevention programs adapted adolescents and their characteristics.

Radiographic Morphometry of the Lumbar Spine in Munich Miniature Pigs†

Engelke, Elisabeth C; Post, Christina; Pfarrer, Christiane D; Sager, Martin; Waibl, Helmut R

2016-01-01

The incidence of human spinal column disease remains high, and animal models still play important roles in prophylactic, diagnostic, and therapeutic research. Because of their similar size to humans, pigs remain an important spine model. For pigs to serve as a model for the human spine, basic similarities and differences must be understood. In this study, morphometric data of the lumbar spine of Munich miniature pigs (Troll) were recorded radiologically, evaluated, and compared with recorded human data. Whereas humans have a constant number of 5 lumbar vertebrae, Munich minipigs had 5 or 6 lumbar vertebrae. Compared with their human counterparts, the lumbar vertebral bodies of the minipigs were remarkably larger in the craniocaudal (superior–inferior) direction and considerably smaller in the dorsoventral and laterolateral directions. The porcine vertebral canal was smaller than the human vertebral canal. The spinal cord extended into the caudal part of the porcine lumbar vertebral canal and thus did not terminate as cranial, as seen in humans. The lumbar intervertebral spaces of the pig were narrower in craniocaudal direction than human intervertebral spaces. These differences need to be considered when planning surgical actions, not only to avoid pain and irreversible damage to the minipigs but also to achieve accurate scientific results. PMID:27177570

A novel algorithm for a precise analysis of subchondral bone alterations

Gao, Liang; Orth, Patrick; Goebel, Lars K. H.; Cucchiarini, Magali; Madry, Henning

2016-01-01

Subchondral bone alterations are emerging as considerable clinical problems associated with articular cartilage repair. Their analysis exposes a pattern of variable changes, including intra-lesional osteophytes, residual microfracture holes, peri-hole bone resorption, and subchondral bone cysts. A precise distinction between them is becoming increasingly important. Here, we present a tailored algorithm based on continuous data to analyse subchondral bone changes using micro-CT images, allowing for a clear definition of each entity. We evaluated this algorithm using data sets originating from two large animal models of osteochondral repair. Intra-lesional osteophytes were detected in 3 of 10 defects in the minipig and in 4 of 5 defects in the sheep model. Peri-hole bone resorption was found in 22 of 30 microfracture holes in the minipig and in 17 of 30 microfracture holes in the sheep model. Subchondral bone cysts appeared in 1 microfracture hole in the minipig and in 5 microfracture holes in the sheep model (n = 30 holes each). Calculation of inter-rater agreement (90% agreement) and Cohen’s kappa (kappa = 0.874) revealed that the novel algorithm is highly reliable, reproducible, and valid. Comparison analysis with the best existing semi-quantitative evaluation method was also performed, supporting the enhanced precision of this algorithm. PMID:27596562

Parents' and young adults' perspectives on transition outcomes for young adults with autism.

Sosnowy, Collette; Silverman, Chloe; Shattuck, Paul

2018-01-01

Existing research shows that young adults with autism spectrum disorder have poorer outcomes than their peers with other developmental disabilities in the key areas of independent living, postsecondary education, and employment. However, we understand little about how young adults with autism and their families understand and value outcomes and whether these indicators match their goals and aspirations. We interviewed parents (n = 21) and young adults with autism spectrum disorder (n = 20) about their experiences with the transition to adulthood to understand what they consider to be desirable outcomes and how they seek to achieve them. Understanding these perspectives will help identify areas of need as well as disconnections between service objectives and the goals of young adults and their families. Participants described outcomes as more complex and nuanced than current conceptions and measures account for. They defined and evaluated outcomes in relation to their or their child's individual abilities, needs, and desires. These findings provide important insight into challenges to and facilitators of desired outcomes, which has implications for programming, service delivery, and policy.

2015-01-01

Background This report is the second part of the previously published study on the impact of light/chemical hardening technology and a newly formulated composite graft material for crestal augmentation during immediate implant placement. Methods A total of 48 implants were placed into the sockets of the mesial roots of freshly extracted mandibular premolar teeth in three minipigs. Crestal areas and intrabony spaces were randomly augmented with light-hardened graft materials including a composite graft consisting of polymethylmethacrylate, polyhydroxylethylmethacrylate, and calcium hydroxide (PPCH) plus polyanhydride (PA); PPCH graft; and PA graft, or left untreated. Distal sockets not receiving implants and the sockets of first molars (n = 60) were randomly treated with one of the graft materials or left empty. In addition, two molar sockets were treated with the original PPCH graft material. Quantitative microcomputed tomography (micro-CT) was used to assess alveolar bone structure and tissue compositions. Histologic evaluations included descriptive histology to assess the peri-implant wound healing, as well as histomorphometric measurements to determine bone-to-implant contact (BIC). Results Both trabecular and cortical bone measurements by micro-CT did not reveal any significant differences among the groups. Sites augmented with PPCH+PA resulted in significantly greater BIC surface than PPCH alone and no-graft-treated implants (P implant surface in the PPCH+PA group, whereas sites without augmentation showed large gaps between bone and implant surfaces, indicating a slower bone apposition and less BIC surface compared to all other groups. Similar to implant sections, all materials showed positive outcome on trabecular and cortical bone formation in extraction sockets with an intact crestal cortical bone. Conclusion Histologic evaluations supported the previous findings on implant stability and function and confirmed that PPCH+PA provides a greater BIC with a

Postsecondary Employment Experiences Among Young Adults With an Autism Spectrum Disorder RH: Employment in Young Adults With Autism

Science.gov (United States)

Roux, Anne M.; Shattuck, Paul T.; Cooper, Benjamin P.; Anderson, Kristy A.; Wagner, Mary; Narendorf, Sarah C.

2013-01-01

Objective We examined postsecondary employment experiences of young adults with an autism spectrum disorder (ASD) and compared these outcomes with those of young adults with different disabilities. Method Data were from Wave 5 of the National Longitudinal Transition Study 2 (NLTS2), a nationally representative survey of young adults who had received special education services during high school. We examined the prevalence of ever having had—and currently having—a paid job at 21–25 years of age. We analyzed rates of full employment, wages earned, number of jobs held since high school, and job types. Results About half (53.4%) of young adults with an ASD had ever worked for pay outside the home since leaving high school, the lowest rate among disability groups. Young adults with an ASD earned an average of $8.10 per hour, significantly lower than average wages for young adults in the comparison groups, and held jobs that clustered within fewer occupational types. Odds of ever having had a paid job were higher for those who were older, from higher-income households, and with better conversational abilities or functional skills. Conclusions Findings of worse employment outcomes for young adults with an ASD suggest this population is experiencing particular difficulty in successfully transitioning into employment. Research is needed to determine strategies for improving outcomes as these young adults transition into adulthood. PMID:23972695

Young people's perspectives on health-related risks

Directory of Open Access Journals (Sweden)

Grace Elisabeth Spencer

2008-07-01

Full Text Available Drawing upon current socio-cultural understandings of risk, this study highlights the disjunction between the expert risk discourses that permeate official public health policy and practice, and young people’s own perspectives on health and risk. Data were collected from young people aged 14-16 years through the use of group and individual interviews in a school and community youth centre setting. Findings from this study question the saliency of expert-defined health-related risks to young people’s everyday lives. Young people in this study saw health as closely linked to ‘being happy’. Friendships and a sense of personal achievement were particularly important to participants’ health and well-being. When accounting for their participation in health-related practices identified as ‘risky’ in government policy – such as smoking, alcohol and substance use – young people emphasised the levels of pressure they experienced. Sources of pressure included arguments and bullying, school work, and negative stereotypes of young people in general. These areas indicated young people’s concerns that reach beyond the official prescriptions permeating current health policy.

On imitation among young and blind children

Directory of Open Access Journals (Sweden)

Maria Rita Campello Rodrigues

2016-07-01

Full Text Available This article investigates the imitation among young and blind children. The survey was conducted as a mosaic in the time since the field considerations were taken from two areas: a professional experience with early stimulation of blind babies and a workshop with blind and low vision young between 13-18 years. By statingthe situated trace of knowledge, theresearch indicates that imitation among blind young people can be one of the ways of creating a common world among young blind and sighted people. Imitation among blind young is a multi-sensory process that requires a body experience, including both blind and people who see. The paper concludes with an indication of the unique character of imitation and at the same time, with the affirmation of its relevance to the development and inclusion process of both the child and the young blind.

Full Text Available Dževdet Smajlović Department of Neurology, University Clinical Centre Tuzla, School of Medicine, University of Tuzla, Bosnia and Herzegovina Abstract: Strokes in young adults are reported as being uncommon, comprising 10%–15% of all stroke patients. However, compared with stroke in older adults, stroke in the young has a disproportionately large economic impact by leaving victims disabled before their most productive years. Recent publications report an increased incidence of stroke in young adults. This is important given the fact that younger stroke patients have a clearly increased risk of death compared with the general population. The prevalence of standard modifiable vascular risk factors in young stroke patients is different from that in older patients. Modifiable risk factors for stroke, such as dyslipidemia, smoking, and hypertension, are highly prevalent in the young stroke population, with no significant difference in geographic, climatic, nutritional, lifestyle, or genetic diversity. The list of potential stroke etiologies among young adults is extensive. Strokes of undetermined and of other determined etiology are the most common types among young patients according to TOAST (Trial of Org 10172 in Acute Stroke Treatment criteria. Prevention is the primary treatment strategy aimed at reducing morbidity and mortality related to stroke. Therefore, primary prevention is very important with regard to stroke in young adults, and aggressive treatment of risk factors for stroke, such as hypertension, smoking, and dyslipidemia, is essential. The best form of secondary stroke prevention is directed toward stroke etiology as well as treatment of additional risk factors. However, there is a lack of specific recommendations and guidelines for stroke management in young adults. In conclusion, strokes in young adults are a major public health problem and further research, with standardized methodology, is needed in order to give us more

Vargas, Gabriela; Borus, Joshua; Charlton, Brittany M

2017-08-01

Although teenage pregnancy is declining in many parts of the world, it remains associated with considerable social, health, and economic outcomes. Pregnancy prevention efforts focus primarily on young women, with minimal attention to young men. This review highlights recent literature pertaining to the role of young men in pregnancy prevention. Young men have varying views on contraception as well as which partner(s) should be responsible for its use. Limited contraception knowledge reduces young men's sexual health communication as well as their contraception use. Healthcare providers play a major role as one of the main sources of sexual health information for young men, but there are gaps in young men's sexual health care so new guidelines have emerged. Recent literature highlights young men's range of views on contraception as well as their low sexual health knowledge and sexual health communication. To address teenage pregnancy and improve young men's overall wellness, healthcare providers should routinely address sexual health. Healthcare providers may use our newly proposed acronym, HIS BESTT, (Hello. Initiate. Sexual health assessment. Both condoms and female dependent methods. Examine genitals. STI screening. Talking to partner(s). Talking to parent(s) or guardians), to incorporate current clinical recommendations.

Epidemiological and family studies have provided evidence on the role of genetic factors in stroke, particularly in stroke occurring at young age. However, despite its impact, young stroke continues to be understudied. This article reviews the existing literature on the most investigated monogenic disorders (CADASIL, Fabry disease, MELAS, RVCL, COL4A1, Marfan and Ehlers-Danlos syndromes) causing stroke in young and a number of candidate genes associated with stroke occurring in patients younger than 50 years. Although our study failed in identifying strong and reliable associations between specific genes and young stroke, our detailed literature revision on the field allowed us to compile a panel of genes possibly generating a susceptibility to stroke, which could be a starting point for future research. Since stroke is a potentially preventable disease, the identification of genes associated with young stroke may promote novel prevention strategies and allow the identification of therapeutic disease targets.

Young Adults Failure to Thrive Syndrome

Directory of Open Access Journals (Sweden)

Warren C. Sanderson

2014-03-01

Full Text Available Many young working age adults in developed countries are failing to thrive in economic, demographic and social terms. Their failure to thrive is a relatively new phenomenon that has not been widely recognized, but it affects young adults in virtually all the more developed countries for which we have relevant data. Young adults nowadays are more often in poverty. They are leaving their parental homes at ever later ages and in some countries the frequency of psychological problems increased. The seriousness of failure to thrive syndrome is reflected in the relationship between relative economic conditions and increased suicide rates. The syndrome is important because young adults are at the prime ages for finding employment, establishing long-run career paths and building an economic basis for founding a family. Developing strategies to arrest the spread of failure to thrive syndrome among young adults, in order to keep them vibrant contributors to our societies, should be a priority for policy makers.

CARBOHYDRATE INTAKE CONSIDERATIONS FOR YOUNG ATHLETES

Directory of Open Access Journals (Sweden)

Veronica Montfort-Steiger

2007-09-01

Full Text Available Good nutritional practices are important for exercise performance and health during all ages. Athletes and especially growing children engaged in heavy training have higher energy and nutrient requirements compared to their non-active counterparts. Scientific understanding of sports nutrition for the young athlete is lacking behind the growing number of young athletes engaged in sports. Most of the sports nutrition recommendations given to athletic children and adolescents are based on adult findings due to the deficiency in age specific information in young athletes. Therefore, this review reflects on child specific sports nutrition, particularly on carbohydrate intake and metabolism that distinguishes the child athlete from the adult athlete. Children are characterised to be in an insulin resistance stage during certain periods of maturation, have different glycolytic/metabolic responses during exercise, have a tendency for higher fat oxidation during exercise and show different heat dissipation mechanisms compared to adults. These features point out that young athletes may need different nutritional advice on carbohydrate for exercise to those from adult athletes. Sport drinks for example may need to be adapted to children specific needs. However, more research in this area is warranted to clarify sports nutrition needs of the young athlete to provide better and healthy nutritional guidance to young athletes

Anita Skelin Horvat

2011-06-01

Full Text Available The media are an important tool for creating public opinion and they can influence the creation of laws and policy. Media representation of young people is important because it can influence the public image of them and it can also influence the young themselves. On the other side, young people can be discriminated against and treated with suspicion because of a specific media image of them. In this paper we analyse a corpus of newspaper articles about violence among the young that occurred in Croatia recently. Analysing this discourse we try to find out who the participants are and what they emphasise as the most important questions and issues in connection with the young and violence. We try to find out how the creation of a text is influenced by power relations and other factors connected with the media (i.e. public opinion, stereotypes, public panic and what the main image of the young created by the media is. We also analyse how language is used and which language and discourse elements (i.e. style, metaphors, and collocations are used in creating a specific media image of the young.

Boumans, Nicolle P G; Dorant, Elisabeth

2018-05-15

Most young carer studies on parentification, resilience and coping concentrated on child carers up to age 18 years, whereas the group of young adult caregivers (18-24 years) has been neglected. In our study, we focused on these young adult caregivers, who are in a life phase in which young people usually are distancing themselves from their families and are striving for autonomy and freedom. To explore young adult carers' perceptions of parentification, resilience and coping compared to young adult noncarers. Cross-sectional. In 2014/2015, data were collected on 297 healthcare students from a school for vocational education and a university in the Netherlands. A fully structured questionnaire was used. Young adult carers were compared with young adult noncarers on parentification, resilience and coping. Fifty-six students identified themselves as a carer: 40 vocational education students and 16 university students. Carers scored significantly higher than noncarers on three out of six parentification dimensions. No differences were found for resilience and problem-focused coping behaviour, whereas results for emotion-focused coping demonstrated a higher score for the carers compared to the noncarers. Although it is important to take care of the needs of all young carers, special attention should be given to those who are at the start of their adult lives, undergoing extensive changes and taking major decisions on study and career issues. Home-care professionals and school counsellors should be able to recognise this group and their needs and activate support from specialised services and significant others. © 2018 The Authors.

Enabling all young Australians to grow up safe, happy, healthy and resilient: a Collaboration for Young People, Technology and Wellbeing.

Science.gov (United States)

2011-07-01

This paper describes a framework for a multi-disciplinary collaboration to investigate the role of technology for improving young Australians' mental health and wellbeing. The poor mental health of young Australians poses a significant challenge to Australia's future. Half of all Australians will experience a mental health difficulty in their lifetime and 75% of mental illness has its onset before age 25. Cross-sectoral collaboration is critical for meeting this challenge. In order to establish a world-first multi-partner collaboration, leading researchers and institutes, commercial, non-profit and end-user organization and young people were identified and invited to participate. Together we have developed an international research framework that explores the role of technologies in young people's lives, their potential and how this can be harnessed to address challenges facing young people. This research framework will: (i) conduct empirical research that tests the utility of technology across mental health promotion, prevention, early intervention and treatment and, (ii) translate existing and new knowledge into products and services that help create a generation of safe, happy, healthy and resilient young people. Research undertaken by the Collaboration will be the most comprehensive investigation of technologies' potential to improve the wellbeing of young people ever conducted, leading to significant benefits for Australian young people and their mental health.

The United Nations' position is that digital access is a matter involving equality between groups of people, the securing of democratic rights, and equal opportunities for all citizens. This study investigates digital equality in school and leisure between young people with and without disabilities. A cross-sectional design with group comparisons was applied. Participants were young people (10-18 years of age) with disabilities (n=389) and a reference group in about the same ages. Data were collected by a survey focusing on access to and engagement in ICT activities in school and during leisure time. The results demonstrated young people with disabilities had restricted participation in computer use in educational activities, in comparison to young people in general. During leisure time young people with disabilities had a leading position compared to the reference group with respect to internet use in a variety of activities. Beneficial environmental conditions at home (and the reverse in schools) are discussed as parts of the explanation for the differing engagement levels at home and in school, and among young people with disabilities and young people in general. Schools need to prioritise use of ICT by young people with disabilities.

New morbidity of the young

Directory of Open Access Journals (Sweden)

Stanković Biljana

2002-01-01

Full Text Available In the present phase of epidemiological transition, the most frequent causes of youth morbidity are disorders in reproductive health, mental disorders and injuries which are not life threatening. This, so-called new youth morbidity, is most often caused by their risky behavior, which in the field of sexuality often leads to unplanned pregnancies and abortions, as well as sexually transmitted infections. Misuse of tobacco, alcohol and narcotics, which is most commonly started in adolescence, has an unfavorable short-term and long-term influence on the psycho-physical health of the young. All research, in the world and in our country, indicate gradual yet constant growth of sexual activity of the youth and the age decrease of its starting point, especially when girls are in question. Due to insufficient maturity and inadequate knowledge and consciousness on the necessity of protecting reproductive health, sexual behavior of young people can often be characterized as insufficiently responsible and not supplemented with the usage of adequate protective measures. The result is frequently abortion, which terminates 90% of unplanned and unwanted pregnancies in this age. This creates health and psychosocial risks, as well as giving birth in adolescence which is contrary to the modern health concepts that giving birth should not be performed too early, while the young are still developing. A significant increase in the frequency of sexually transmitted diseases is also present, to which the youth are especially susceptible due to the specific development period in which they are in. A serious medical and sociopathological problem of contemporary society represents the greater and greater misuse of psychoactive substances among the young people, with a tendency of decreasing the average age they are consumed for the first time, as well as the use of drugs and alcohol. With the increase of the anti-smoking campaign and restrictive measures in highly

Art has been shown to be an empowering and engaging entity with numerous benefits to vulnerable populations, including the homeless persons and young adults. However, little is known how homeless young adults perceive the use of art as messages that can communicate the danger of initiating or continuing drug and alcohol use. The purpose of this study was to solicit perspectives of homeless, drug-using young adults as to how art can be used to design messages for their peers about the danger of initiating or continuing drug and alcohol use. Qualitative methodology via focus group discussions was utilized to engage 24 homeless young adults enrolled from a drop-in site in Santa Monica, California. The findings revealed support for a myriad of delivery styles, including in-person communication, flyers, music, documentary film, and creative writing. The young adults also provided insight into the importance of the thematic framework of messages. Such themes ranged from empowering and hopeful messages to those designed to scare young homeless adults into not experimenting with drugs. The findings indicate that in addition to messages communicating the need to prevent or reduce drug and alcohol use, homeless young adults respond to messages that remind them of goals and dreams they once had for their future, and to content that is personal, real, and truthful. Our research indicates that messages that reinforce protective factors such as hope for the future and self-esteem may be as important to homeless young adults as information about the risks and consequences of drug use.

Objectives To identify key health outcomes, beyond morbidity and mortality, regarded as important in children and young people with neurodisability, and their parents. Design Qualitative research incorporating a thematic analysis of the data supported by the Framework Approach; the International Classification of Functioning, Disability and Health (ICF) provided a theoretical foundation. Setting The study was conducted in community settings. Participants Participants were 54 children and young people with neurodisability: 50 participated in focus groups, and 4 in interviews; 53 parents participated: 47 in focus groups and 6 in interviews. Children/young people and parents were recruited through different networks, and were not related. Results Children/young people and parents viewed health outcomes as inter-related. Achievement in some outcomes appeared valued to the extent that it enabled or supported more valued domains of health. Health outcomes prioritised by both young people and parents were: communication, mobility, pain, self-care, temperament, interpersonal relationships and interactions, community and social life, emotional well-being and gaining independence/future aspirations. Parents also highlighted their child's sleep, behaviour and/or safety. Conclusions Those responsible for health services for children/young people with neurodisability should take account of the aspects of health identified by families. The aspects of health identified in this study provide a basis for selecting appropriate health indicators and outcome measures. PMID:24747792

Recently, a new urodynamic method for the assessment of stress urinary incontinence called high definition urethral pressure profilometry (HD-UPP) has been introduced. This method combines a novel microtip catheter with advanced signal processing to enable spatial data location and the reconstruction of a pressure image inside the urethra. In order to assess the reproducibility of HD-UPP data, we statistically evaluate HD-UPP datasets and compare them to data from a double balloon air-charged system. Both catheters are used on sedated female minipigs. Data from the microtip catheter are processed through a signal reconstruction algorithm, urodynamic features are extracted, and compared to the air-charged system. Reproducibility of HD-UPP data is assessed by statistically evaluating consecutive, intra-individual datasets. HD-UPP delivers results in agreement with previous comparisons of microtip and air-charged systems. The average deviation of two consecutive, intra-individual pressure images is very low at 7 cm H 2 O. HD-UPP provides physicians with detailed information on the pressure distribution inside the urethra. Through comparison with an air-charged catheter, it is shown that HD-UPP delivers results in agreement with previous studies on the comparison of microtip and air-charged catheters. It provides excellent reproducibility, as the difference between sequentially measured profiles from the same minipig is significantly lower than the one between profiles from different minipigs. © 2016 Wiley Periodicals, Inc.

Childhood Origins of Young Adult Environmental Behavior.

Science.gov (United States)

Evans, Gary W; Otto, Siegmar; Kaiser, Florian G

2018-05-01

Prospective, longitudinal analyses revealed that over a 12-year period from ages 6 to 18, individuals who grew up with mothers with more proenvironmental attitudes engaged in more proenvironmental behavior as young adults. A similar marginal association was uncovered between mothers' proenvironmental behaviors and the proenvironmental behavior of their young adult offspring. Maternal educational attainment, but not political ideology, was also associated with more proenvironmental behavior as children matured. Moreover, childhood time spent outdoors was positively associated with increased environmentally responsible behavior in young adulthood. Interestingly, one's own childhood proenvironmental behavior and attitude, at least as assessed at age 6, bear little on one's eventual proenvironmental behavior as a young adult. Finally, among this set of childhood factors, maternal education and childhood time spent outdoors were independent predictors of positive changes in environmental behavior from early childhood to young adulthood.

Young adults have the highest smoking rate of any age group in the U.S., and new strategies to decrease young adult smoking are needed. The objective of the current study was to identify psychographic and demographic factors associated with current smoking and quitting behaviors among young adults. Attitudes, social groups, and self-descriptors, including supporting action against the tobacco industry, advertising receptivity, depression, alcohol use, and other factors associated with smoking were tested for associations with smoking behaviors in a 2005 cross-sectional survey of 1528 young adults (aged 18-25 years) from a web-enabled panel. Analyses were conducted in 2007. Being older was associated with current smoking, whereas having some higher education and being African American or Hispanic were negatively associated with smoking. Supporting action against the tobacco industry was negatively associated with smoking (AOR=0.34 [95% CI=0.22, 0.52]). Perceived usefulness of smoking, exposure to smokers, increased perceived smoking prevalence, receptivity to tobacco advertising, binge drinking, and exposure to tobacco advertising in bars and clubs were associated with smoking. Supporting action against the tobacco industry was associated with intentions to quit smoking (AOR=4.43 [95% CI=2.18, 8.60]). Young adults are vulnerable to tobacco-industry advertising. Media campaigns that denormalize the tobacco industry and appeal to young adults appear to be a powerful intervention to decrease young adult smoking.

There is a need for youth-friendly hospital environments as the ward environment may affect both patient satisfaction and health outcomes. To involve young people in designing youth-friendly ward environment. We arranged a design competition lasting 42 h (Hackathon). Students in architecture, design, engineering, communication and anthropology participated (27 young adults) - forming eight groups. Adolescents and young adults (AYA) with current or former cancer experience participated as sparring partners. We provided workspace and food during the weekend. The groups presented their products to a jury and relevant stakeholders. The groups created eight unique design concepts. The young designers were extremely flexible listening to ideas and experiences from the young patients, which led to common features including individual and flexible design, privacy in two-bed wardrooms and social contact with other hospitalized AYA. The winning project included an integrated concept for both wardrooms and the AYA day room, including logos and names for the rooms and an 'energy wall' in the day room. A hackathon event was an effective mode of youth participation. The design concepts and ideas were in line with current evidence regarding pleasing hospital environment and youth-friendly inpatient facilities and may be applicable to other young patients.

OBJECTIVES While progress has been made to reduce adolescent pregnancies in the United States, rates of unplanned pregnancy among young adults (18–29 years) remain high. In this study, we assessed factors associated with perceived likelihood of pregnancy (likelihood of getting pregnant/getting partner pregnant in the next year) among sexually experienced young adults who were not trying to get pregnant and had ever used contraceptives. METHODS We conducted a secondary analysis of 660 young adults, 18–29 years old in the United States, from the cross-sectional National Survey of Reproductive and Contraceptive Knowledge. Logistic regression and classification tree analyses were conducted to generate profiles of young adults most likely to report anticipating a pregnancy in the next year. RESULTS Nearly one-third (32%) of young adults indicated they believed they had at least some likelihood of becoming pregnant in the next year. Young adults who believed that avoiding pregnancy was not very important were most likely to report pregnancy likelihood (odds ratio [OR], 5.21; 95% CI, 2.80–9.69), as were young adults for whom avoiding a pregnancy was important but not satisfied with their current contraceptive method (OR, 3.93; 95% CI, 1.67–9.24), attended religious services frequently (OR, 3.0; 95% CI, 1.52–5.94), were uninsured (OR, 2.63; 95% CI, 1.31–5.26), and were likely to have unprotected sex in the next three months (OR, 1.77; 95% CI, 1.04–3.01). DISCUSSION These results may help guide future research and the development of pregnancy prevention interventions targeting sexually experienced young adults. PMID:25782849

Children and young people are seen as fundamental to the design and delivery of clinical research as active and reflective participants. In Europe, involvement of children and young people in clinical research is promoted extensively in order to engage young people in research as partners and to give them a voice to raise their own issues or opinions and for their involvement in planning and decision making in addition to learning research skills. Children and young people can be trained in clinical research through participation in young person advisory groups (YPAGs). Members of YPAGs assist other children and young people to learn about clinical research and share their experience and point of view with researchers, thereby possibly influencing all phases of research including the development and prioritization of research questions, design and methods, recruitment plans, and strategies for results dissemination. In the long term, the expansion of YPAGs in Europe will serve as a driving force for refining pediatric clinical research. It will help in a better definition of research projects according to the patients' needs. Furthermore, direct engagement of children and young people in research will be favorable to both researchers and young people. © 2018 Société Française de Pharmacologie et de Thérapeutique.

MARRIAGE AND MENTAL HEALTH AMONG YOUNG ADULTS

Uecker, Jeremy E.

2012-01-01

Marriage is widely thought to confer mental health benefits, but little is known about how this relationship may vary across the life course. Early marriage—which is non-normative—could have no, or even negative, mental health consequences for young adults. Using survey data from Waves 1 and 3 of the National Longitudinal Study of Adolescent Health (N = 11,743), I find that married young adults exhibit similar levels of psychological distress as young adults who are in any kind of romantic relationship. Married and engaged young adults report lower rates of drunkenness than others. Married young adults—especially those who first married at age 22–26—report higher life satisfaction than those in other types of relationships or no relationship at all, as well as those who married at younger ages. Explanations for these findings are examined, and their implications are discussed. PMID:22328171

Li, Ian W; Si, Jiawei

2016-11-01

Objective The aim of the present study was to estimate the revenues collected by government and industry from alcohol consumption by young Australians in 2010. Methods Statistical analyses were performed on data from the Australian National Drug Strategy Household Survey 2010 and alcohol data collected from an online retailer to calculate the proportion, frequency, quantity and revenues from alcohol consumption by young Australians. Results One-third of adolescents (12-17 years old) and 85% of young adults (18-25 years old) consume alcohol. More than half the adolescents' alcohol consumption is from ready-to-drink spirits. Revenue generated from alcohol consumption by 12-25 year olds is estimated at $4.8 billion in 2010 (2014 Australian dollars): $2.8 billion to industry (sales) and $2.0 billion to government (taxes). Conclusions Alcohol consumption by young Australians is prevalent, and young Australian drinkers consume alcohol in substantial amounts. The industry and taxation revenue from young drinkers is also considerable. It would be in the public interest to divert some of this revenue towards health initiatives to reduce drinking by young people, especially given the high societal costs of alcohol consumption. What is known about the topic? Australian adolescents aged 12-17 years consume substantial amounts of alcohol, and substantial amounts of revenue are generated from alcohol sales to them. What does this paper add? This paper provides recent estimates of alcohol consumption and revenue generated by Australian adolescents, and extends estimates to young adults aged 18-25 years. What are the implications for practitioners? A substantial proportion of Australian young people consume alcohol. The sales and taxation revenue generated from young people's drinking is substantial at A$4.8 billion in 2010 and is higher in real terms than estimates from previous studies. Some of the alcohol taxation revenue could be diverted to health promotion and education for

Palmaz, J.C.; Hayashi, H.; Schatz, R.; Hunter, G.; Tio, F.O.; Garcia, O.

1986-01-01

Balloon expandable intraluminal grafts were placed in renal arteries of eight adult dogs and 11 minipigs. The renal arteries were normal in the dogs before graft placement. Two grafts were placed in primary division branches and the rest in the main renal artery. Experimental renal artery stenosis was created in the minipigs by subocclusive ligature of the renal artery with absorbable suture material. Six months later significant renal artery stenoses developed in six pigs and were corrected by graft placement. In the remaining pigs grafts were placed in the opposite normal renal artery because the stenosis caused a small, shrunken kidney in two, and severe spasm or anatomic variations prevented graft placement in three. All grafts remained patent on angiographic and pathologic examinations to a maximum follow-up to 24 weeks

Life history strategy and young adult substance use.

Richardson, George B; Chen, Ching-Chen; Dai, Chia-Liang; Swoboda, Christopher M

2014-11-03

This study tested whether life history strategy (LHS) and its intergenerational transmission could explain young adult use of common psychoactive substances. We tested a sequential structural equation model using data from the National Longitudinal Survey of Youth. During young adulthood, fast LHS explained 61% of the variance in overall liability for substance use. Faster parent LHS predicted poorer health and lesser alcohol use, greater neuroticism and cigarette smoking, but did not predict fast LHS or overall liability for substance use among young adults. Young adult neuroticism was independent of substance use controlling for fast LHS. The surprising finding of independence between parent and child LHS casts some uncertainty upon the identity of the parent and child LHS variables. Fast LHS may be the primary driver of young adult use of common psychoactive substances. However, it is possible that the young adult fast LHS variable is better defined as young adult mating competition. We discuss our findings in depth, chart out some intriguing new directions for life history research that may clarify the dimensionality of LHS and its mediation of the intergenerational transmission of substance use, and discuss implications for substance abuse prevention and treatment.

Ireland, Jane L

2002-04-01

This study compares bullying behaviour among juvenile and young offenders and incorporates two different methods to measure bullying. Ninety-five male juvenile and 196 male young offenders completed two questionnaires, one that measured bullying directly and one that measured behaviours indicative of "being bullied" or of "bullying others". Juveniles perceived a higher extent of bullying than young offenders. Juveniles reported significantly more physical, psychological or verbal and overall direct forms of bullying behaviour than young offenders. A number of differences were found between juveniles and young offenders with regard to the types of prisoners likely to become victims, who they would advise a victim to speak to and how bullying could be prevented. The results are discussed in relation to developmental theories of aggression and how bullying behaviour can be defined and measured among prisoners.

2016-01-01

While the recent Coalition government committed to some initiatives supporting the role of parents, relationships and the early years, there remains a lack of focus on fathers as a distinct policy area. This is reflected at local government level, as lead professionals for young fathers are rare and data on the number of young fathers in each local area are not routinely collected. Barnardo's was funded by the Department for Education in 2012, as part of the Family Strategic Partnership, to highlight the needs and experiences of young fathers in England, and the joint role of statutory and voluntary services in supporting them (fully reported by Barnardo's in Cundy, 2012). Based on selected case studies drawn from research and a range of practice organisations, this article presents the journeys of five young fathers and their experience of maternity services, children's centres, schools, housing services and the secure estate.

2015-12-25

With around 40,000 members in more than 150 countries, American Society for Microbiology (ASM) faces the challenge of meeting very diverse needs of its increasingly international members base. The newly launched ASM Young Ambassador Program seeks to aid the Society in this effort. Equipped with ASM conceptual support and financing, Young Ambassadors (YAs) design and pursue country-tailored approaches to strengthen the Society's ties with local microbiological communities. In a trans-national setting, the active presence of YAs at important scientific events, such as 16th European Congress on Biotechnology, forges new interactions between ASM and sister societies. The paper presents an overview of the Young Ambassadors-driven initiatives at both global and country levels, and explores the topic of how early-career scientists can contribute to science diplomacy and international relations.

Young adults at work without basic educational level (BEL), and young adults in Neither Employment, Education nor Training (NEET) are at high risk of adverse employment outcomes. Evidence lacks on the impact of mental health problems during childhood, adolescence and young adulthood on employment outcomes of young adults. Therefore, the aims of this study were to (1) identify trajectories of mental health problems from childhood to young adulthood and (2) investigate the relation between these trajectories and the educational or employment status of young adults. Data were used from the Tracking Adolescents' Individual Lives Survey (TRAILS), a Dutch prospective cohort study with 9-year follow-up. Trajectories of mental health problems measured at ages 11, 13.5, 16 and 19 years were identified in 1711 young adults with latent class growth models. Young adults with high-stable trajectories of total problems, from childhood to young adulthood, were more likely to work without BEL or be in NEET at age 19, than to be at school or to work with BEL (28.0% vs 16.0%, p=0.01). The same was found for externalising problems (35.3% vs 23.2%, p=0.02). For internalising and attention problems, no statistically significant differences were found. Young adults with high-stable trajectories of mental health problems from age 11 to 19, were at risk of adverse employment outcomes. Interventions reducing mental health problems in childhood may improve the educational or employment status of young adults and their chances for successfully entering the labour market.

Although sex and relationship education (SRE) represents a key strand in policies to safeguard young people and improve their sexual health, it currently lacks statutory status, government guidance is outdated and a third of UK schools has poor-quality SRE. We aimed to investigate whether current provision meets young people's needs. Synthesis of qualitative studies of young people's views of their school-based SRE. Eligible studies originated from the UK, Ireland, the USA, Australia, New Zealand, Canada, Japan, Iran, Brazil and Sweden. Studies of students aged 4-19 in full-time education, young adults ≤19 (not necessarily in full-time education) or adults ≤25 if recalling their experiences of school-based SRE. -69 publications were identified, with 55 remaining after quality appraisal (representing 48 studies). The synthesis found that although sex is a potent and potentially embarrassing topic, schools appear reluctant to acknowledge this and attempt to teach SRE in the same way as other subjects. Young people report feeling vulnerable in SRE, with young men anxious to conceal sexual ignorance and young women risking sexual harassment if they participate. Schools appear to have difficulty accepting that some young people are sexually active, leading to SRE that is out of touch with many young people's lives. Young people report that SRE can be negative, gendered and heterosexist. They expressed dislike of their own teachers delivering SRE due to blurred boundaries, lack of anonymity, embarrassment and poor training. SRE should be 'sex-positive' and delivered by experts who maintain clear boundaries with students. Schools should acknowledge that sex is a special subject with unique challenges, as well as the fact and range of young people's sexual activity, otherwise young people will continue to disengage from SRE and opportunities for safeguarding and improving their sexual health will be reduced.

Although the genetic contribution to stroke risk is well known, it remains unclear if young-onset stroke has a stronger genetic contribution than old-onset stroke. This study aims to compare the heritability of ischaemic stroke risk between young and old, using common genetic variants from whole-genome array data in population-based samples. This analysis included 4050 ischaemic stroke cases and 5765 controls from six study populations of European ancestry; 47% of cases were young-onset stroke (age stroke risk in these unrelated individuals, the pairwise genetic relatedness was estimated between individuals based on their whole-genome array data using a mixed linear model. Heritability was estimated separately for young-onset stroke and old-onset stroke (age ≥ 55 years). Heritabilities for young-onset stroke and old-onset stroke were estimated at 42% (±8%, P genetic contribution to the risk of stroke may be higher in young-onset ischaemic stroke, although the difference was not statistically significant. © 2015 EAN.

Attending to others: how digital technologies direct young people's nightlife

Directory of Open Access Journals (Sweden)

J. Truong

2018-05-01

Full Text Available It is a growing phenomenon that young people use mobile information and communication technologies during their nightlife. This article offers an empirical examination of how young people's nightlife is shaped by engagement with the mobile phone application WhatsApp. Drawing on Sara Ahmed's phenomenological concept of orientation, I examine how WhatsApp extends young people's nightlife and how young people become orientated therein. On the one hand, I show that nightlife acquires new boundaries and fixities that encourage young people to direct their attention towards missing social relations and absent nightlife places. On the other hand, I find that young people create new perceptions of how to inhabit and spend leisure time and space. I argue that digital technologies reorientate young people, which I suggest offers novel means of addressing young people's contemporary nightlife practices, places, spaces, and social relations.

2009-09-01

To ascertain information about the use of mobile phones on a young person's hospital unit and to obtain the views of nursing staff and young people about the benefits of their use. A qualitative study using a pre-piloted questionnaire was given to 50 young people admitted consecutively to the young person's unit of district general hospital in a four-week period. A separate questionnaire was given to nine members of the nursing team over the same time period. Most young people had access to a mobile phone while on the ward. A total of 30 per cent were told they could use their phone, 75 per cent of those had made calls or sent texts while on the ward, 80 per cent had received calls or texts, and 20 per cent had used the ward phone at the nursing station. All staff agreed that it was helpful for young people to use their phones on the ward to keep in contact with friends and family, to avoid isolation and ease boredom. Young people have different social needs to younger children and appreciate the opportunity to use mobile phones. A more flexible approach should be adopted. The advantages of phone use clearly outweigh the risks.

Young Women, Sexual Behaviour and Sexual Decision-Making

Directory of Open Access Journals (Sweden)

Lesley Hoggart

2006-01-01

Full Text Available This paper considers young people's sexual decision-making in the context of New Labour's policies on teenage pregnancy. In 1999, the newly formed Social Exclusion Unit sought to understand why the UK had the highest number of teenage conceptions in Europe (SEU 1999. One of the conclusions was that young people in the UK are engaging in "risky" rather than "safe" sex. Although New Labour has since developed policies designed to help young people avoid what is seen as risky sexual activity, there is a tension in sexual health policy between the overall aim of providing young people with the knowledge and confidence to practice "safe sex", and an underlying belief amongst many in the undesirability of "underage sex". This is partly a legacy of disagreements evident in the 1980s and 1990s when some organisations argued against sex education and contraceptive provision for young people on the grounds that it encouraged promiscuous and risky behaviour. The paper shows how alternative meanings of risk and responsibility are present in young mothers' own representations of their sexual decision-making. It does this through an analysis of two research projects on Young Women, Sex and Choices. URN: urn:nbn:de:0114-fqs0601283

SURPRISINGLY WEAK MAGNETISM ON YOUNG ACCRETING BROWN DWARFS

International Nuclear Information System (INIS)

Reiners, A.; Basri, G.; Christensen, U. R.

2009-01-01

We have measured the surface magnetic flux on four accreting young brown dwarfs and one nonaccreting young very low mass (VLM) star utilizing high-resolution spectra of absorption lines of the FeH molecule. A magnetic field of 1-2 kG had been proposed for one of the brown dwarfs, Two Micron All Sky Survey (2MASS) J1207334-393254, because of its similarities to higher mass T Tauri stars as manifested in accretion and the presence of a jet. We do not find clear evidence for a kilogauss field in any of our young brown dwarfs but do find a 2 kG field on the young VLM star. Our 3σ upper limit for the magnetic flux in 2MASS J1207334-393254 just reaches 1 kG. We estimate the magnetic field required for accretion in young brown dwarfs given the observed rotations, and find that fields of only a few hundred gauss are sufficient for magnetospheric accretion. This predicted value is less than our observed upper limit. We conclude that magnetic fields in young brown dwarfs are a factor of 5 or more lower than in young stars of about one solar mass, and in older stars with spectral types similar to our young brown dwarfs. It is interesting that, during the first few million years, the fields scale down with mass in line with what is needed for magnetospheric accretion, yet no such scaling is observed at later ages within the same effective temperature range. This scaling is opposite to the trend in rotation, with shorter rotation periods for very young accreting brown dwarfs compared with accreting solar-mass objects (and very low Rossby numbers in all cases). We speculate that in young objects a deeper intrinsic connection may exist between magnetospheric accretion and magnetic field strength, or that magnetic field generation in brown dwarfs may be less efficient than in stars. Neither of these currently has an easy physical explanation.

Simulation Frames: Young Adult Dystopian Cinema

Directory of Open Access Journals (Sweden)

Alison Tedman

2015-07-01

Full Text Available This article examines the ways in which Young Adult dystopian film Divergent (2014 successfully repurposes dystopia for a young demographic, making dystopia an aesthetically appealing space for heroic adventure. The film recombines Young Adult literary tropes with film conventions including those of science fiction. Divergent and other Young Adult dystopian films modify the potential for social critique associated with canonic dystopian fiction. The article’s critical framework includes theories of dystopia and of Young Adult dystopian literature, the Freudian uncanny, studies of the post-apocalyptic film city and new media theory. In Divergent, the dystopian division of society into factions is made enjoyable through production design, particularly in ‘Dauntless’, the faction joined by heroine Tris. This extends to transmedia marketing. The book’s violence is reduced to increase audience engagement, while lack of contextual detail precludes a critical dystopia. In Divergent, the spaces and ideologies of the post-apocalyptic film city are reframed as youth culture. Chicago is gamified, connoting an adventure playground. The space of the Dauntless ‘Pit’ offers symbolic rebirth, community and romance, yet its appeal is uncanny, as with communal spaces in The Host (2013 and The Maze Runner (2014. Divergent’s mirror simulation foregrounds spectacle but other simulations construct immediacy, appearing dream-like not immersive. Like the visions in Young Adult dystopian adaptations How I Live Now (2013 and Ender’s Game (2013, simulations convey individual awareness and supernatural communication. The film combines pleasurable classification and a divergence motif with its heroine’s development, revising dystopian cinematic space. Divergent represents a new form of dystopian cinema.

Abstract Aim: The aim of this study was to describe the phenomenon of management by way of the ideas by secondary school students and young nurses. Background: Young adults are changing workplaces more than ever before, yet their work expectations and perspectives of management differ to those of previous generations. Methods: The data was collected from upper secondary school students and professionally educated nurses (n = 68), some of whom were immigrants (n = 41). Framed essays were used as a research method and emergent data was analysed using content analysis. Results: According to the results, good management involves systematic management, equality, appreciation of know-how, and the promotion of wellbeing at work. Conclusion: New perspectives on management were drawn from the study, in particular the multiple dimensions of equality in workplace organization and the manager's role in an employee's professional development process. Implication for nursing management: The interactive skills of the manager are emphasized in promoting wellbeing at work. This is especially so in multi-cultural teams, where the manager is expected to be adept at understanding intercultural communication and the values of young employees.

[Sleep and academic performance in young elite athletes].

Poussel, M; Laure, P; Genest, J; Fronzaroli, E; Renaud, P; Favre, A; Chenuel, B

2014-07-01

In French law (Code du Sport), the status of elite athlete is allowed for young athletes beginning at the age of 12 years. For these young athletes, the aim is to reach the highest level of performance in their sport without compromising academic performance. Training time is therefore often substantial and sleep patterns appear to play a key role in performance recovery. The aim of this study was to assess sleep patterns and their effects on academic performance in young elite athletes. Sleep patterns were assessed using questionnaires completed during a specific information-based intervention on sports medicine topics. The academic performance of young elite athletes was assessed by collecting their grades (transmitted by their teachers). Sleep patterns were assessed for 137 young elite athletes (64 females, 73 males; mean age, 15.7 years) and academic performance for 109 of them. Daily sleep duration during school periods (8h22 ± 38 min) were shorter compared to holidays and week-ends (10h02 ± 1h16, Psleep quality as poor or just sufficient. Poor sleep quality was correlated with poor academic performance in this specific athlete population. Sleep is the most important period for recovery from daily activity, but little information is available regarding the specific population of young elite athletes. The results reported herein suggest insufficiency (quantitatively and qualitatively) of sleep patterns in some of the young athletes, possibly leading to detrimental effects on athletic performance. Moreover, disturbed sleep patterns may also impact academic performance in young elite athletes. Teachers, athletic trainers, physicians, and any other professionals working with young elite athletes should pay particular attention to this specific population regarding the possible negative repercussions of poor sleep patterns on academic and athletic performance.

Young children's harmonic perception.

Science.gov (United States)

Costa-Giomi, Eugenia

2003-11-01

Harmony and tonality are two of the most difficult elements for young children to perceive and manipulate and are seldom taught in the schools until the end of early childhood. Children's gradual harmonic and tonal development has been attributed to their cumulative exposure to Western tonal music and their increasing experiential knowledge of its rules and principles. Two questions that are relevant to this problem are: (1) Can focused and systematic teaching accelerate the learning of the harmonic/tonal principles that seem to occur in an implicit way throughout childhood? (2) Are there cognitive constraints that make it difficult for young children to perceive and/or manipulate certain harmonic and tonal principles? A series of studies specifically addressed the first question and suggested some possible answers to the second one. Results showed that harmonic instruction has limited effects on children's perception of harmony and indicated that the drastic improvement in the perception of implied harmony noted approximately at age 9 is due to development rather than instruction. I propose that young children's difficulty in perceiving implied harmony stems from their attention behaviors. Older children have less memory constraints and more strategies to direct their attention to the relevant cues of the stimulus. Younger children focus their attention on the melody, if present in the stimulus, and specifically on its concrete elements such as rhythm, pitch, and contour rather than its abstract elements such as harmony and key. The inference of the abstract harmonic organization of a melody required in the perception of implied harmony is thus an elusive task for the young child.

[Ischemic stroke in the young adult].

Science.gov (United States)

Calvet, D

2016-01-01

Ischemic stroke is not rare in young adults since one in ten stroke patients are less than 50 years old. This incidence increased over the past last years, mainly due to the rise in the prevalence of traditional vascular risk factors in this sub-group of age but also of illegal drug use. Even though both survival and functional outcome of young stroke patients are better than those observed in older patients, socio-economic and quality of life consequences make this disease a main objective in terms of primary and secondary prevention. Identifying the cause of ischemic stroke in young adults is of major importance to prevent stroke recurrence. However, given the wide variety of potential underlying causes, the etiologic work-up of stroke in young adults requires a different approach from that in the elderly. In this context, a sequential diagnostic work-up is needed in order to optimize the yield of diagnostic tests, to reduce their cost and risks for the patient. Arterial dissection is the most frequent cause of stroke in young adults but other less frequent causes are numerous. Despite a comprehensive work-up, about one third of cases remains unexplained leading to the diagnosis of cryptogenic ischemic stroke.

Activation of antioxidant defenses in whole saliva by psychosocial stress is more manifested in young women than in young men.

Directory of Open Access Journals (Sweden)

Viktoriia Tsuber

Full Text Available Psychosocial stress has been long known to have deleterious effects on health. Nevertheless, an exposure to moderate stressors enhances resilience and promotes health benefits. Male and female organisms differ in many aspects of health and disease. The aim of this study was to investigate antioxidant activity and oxidative damage in saliva in a psychosocial stress paradigm in men and women. Here, we show that an acute stressor of moderate strength augments antioxidant activity and decreases oxidative damage in whole saliva of young people. An examination stress caused a significant increase of catalase activity, accompanied by a decrease of levels of oxidized proteins. Levels of thiobarbituric acid-reacting substances did not increase at stress, indicating that lipid peroxidation was not activated. The stress-induced alterations were more manifested in young women compared to young men. Thus, antioxidant protective mechanisms are more activated by a moderate stressor in young women than in young men.

Don't Explain so Much at Once, and Other Lessons From the Young Reviewers of Frontiers for Young Minds

Science.gov (United States)

Baker, A. M.

2015-12-01

Most public communication about cutting-edge science happens through a series of filters - press teams, science journalists, news outlets, or even bloggers. Unfortunately, these filters can sometimes lead to research being presented in a way that demotivates the researchers from wanting to translate their science for a broader audience in the future. Frontiers for Young Minds was developed to bridge this gap by publishing plain-language research articles that are written by scientists about their own research and "peer reviewed" by kids ages 8-15 for their own young peers. Though Frontiers for Young Minds authors know that they are creating a high-quality science resource that will be freely available online, many are surprised by the lessons they stand to learn by having direct access to their target audience for feedback. The young reviewers can be refreshingly blunt, questioning everything from why money was spent on such a project to why researchers would make something that should be exciting "too boring to even finish reading." Frontiers for Young Minds is compiling this feedback to create guides for researchers who want to translate their research for young readers, including: using your structure as part of the communication process, the dangers of explaining too much at once, reading to learn, limitations in vocabulary for different age groups, outreach figures - vs - research figures, defining your communication goals, communicating motivation and context, and sharing your excitement. We are working to share our experiences and create resources that will not only be useful for people participating in Frontiers for Young Minds, but for anyone who wants to become a better science communicator.

SUICIDAL ATTEMPTS AMONG YOUNG RURAL INHABITANTS

Directory of Open Access Journals (Sweden)

Zdzisław Brzeski

2010-06-01

Full Text Available In recent years changes have been noted in the motivations for acute suicidal poisonings among young people from various environments, which are due to psychosocial changes both in the urban and rural environments. Suicidal attempts are accompanied – especially in the rural environment – by low social status, difficulties with adapting to a free market economy, emotional tension within the family, at school, in the environment of young people, addiction to alcohol, drug overuse, including psychotropes. Based on clinical material concerning rural inhabitants hospitalized due to suicidal poisonings, the authors performed the analysis of attitudes, motivations and causes of acute poisonings among the young rural population. Among rural adolescents who continued school or university education the dominant causes of undertaking a suicidal attempt were: adolescent period problems, conflicts within the family, conflicts with mates, and disappointment in love. Among young adults the motivations were as follows: difficulties with finding employment in the place of residence, conflicts within the family, overuse of stimulants, and sometimes states of depression during the period of aggravation of a disease.

Being young in a boom town

Energy Technology Data Exchange (ETDEWEB)

O' Connor, Christopher

2011-08-15

Fort McMurray is a booming town, having grown from small town to big city in a short time. A study was conducted to determine how this change affected young people. Results show they felt the changing environment required them to adapt all the time, which was a challenge but also a source of opportunities. Fort McMurray, with a labour shortage, afforded young people a lot of well-paid, flexible part time jobs during high school. These jobs were important to fund their post-secondary education. Although most of the young people saw themselves living elsewhere in 10 years, they could possibly stay if local challenges in the city were addressed.

Investing in the health and well-being of young adults.

Stroud, Clare; Walker, Leslie R; Davis, Maryann; Irwin, Charles E

2015-02-01

Contrary to popular perception, young adults-ages approximately 18-26 years-are surprisingly unhealthy. They are less healthy than adolescents, and they also show a worse health profile than those in their late 20s and 30s. The Affordable Care Act provisions to extend coverage for young adults are well known, and some states had already been pursuing similar efforts before the Affordable Care Act was enacted. These initiatives have resulted in important gains in young adults' heath care coverage. However, too little attention has been paid to the care that young adults receive once they are in the system. Given young adults' health problems, this is a critical omission. The Institute of Medicine and National Research Council recently released a report titled Investing in the Health and Well-Being of Young Adults. The report concludes that young adulthood is a critical developmental period and recommends that young adults ages 18-26 years be treated as a distinct subpopulation in policy, planning, programming, and research. The report also recommends action in three priority areas to improve health care for young adults: improving the transition from pediatric to adult medical and behavioral health care, enhancing preventive care for young adults, and developing evidence-based practices.

Maternal obesity negatively affects fetal development. Abnormalities in brain glucose metabolism are predictive of metabolic-cognitive disorders. We studied the offspring (aged 0, 1, 6, 12 months) of minipigs fed a normal vs high-fat diet (HFD), by positron emission tomography (PET) to measure brain glucose metabolism, and ex vivo assessments of brain insulin receptors (IRβ) and GLUT4. At birth, brain glucose metabolism and IRβ were twice as high in the offspring of HFD-fed than control mothers. During infancy and youth, brain glucose uptake, GLUT4 and IRβ increased in the offspring of control mothers and decreased in those of HFD-fed mothers, leading to a 40-85% difference (p brain glucose overexposure during fetal development, followed by long-lasting depression in brain glucose metabolism in minipigs.

Young for young! Mandatory age-matched exchange of paediatric kidneys.

Science.gov (United States)

Pape, Lars; Ehrich, Jochen H H; Offner, Gisela

2007-04-01

Some allocation systems include a mandatory donation of paediatric kidneys to children, others do not. Both approaches have medical and organisational advantages and disadvantages for adults and children. This article discusses why "young for young" is the best allocation system for children. Primary age-matched kidney allocation to children is one important factor leading to: (1) higher long-term glomerular filtration rates (GFRs) and graft survival and, thereby, to lesser need for dialysis; (2) better psychosocial rehabilitation, growth and development of children and, last but not least, (3) likely increase of the donor pool. As a consequence, health care costs will be reduced for children with end-stage renal failure. The chance of adults receiving an adequate kidney would be only minimally reduced by this policy. Therefore, we recommend an age-matched allocation programme giving children with end- stage kidney diseases a better prognosis.

La Taillade, Jaslean J; Hofferth, Sandra; Wight, Vanessa R

2010-04-01

This paper examined how the onset and timing of the transition to fatherhood affects the type and quality of young men's relationships with partners and parents. Data are drawn from the 1979 National Longitudinal Survey of Youth - Young Adult Survey and included young men (ages 18-31 years old in 2006) who varied on residential status with their children and timing of fatherhood (N = 1,931). Results indicated the effects of fatherhood varied across types of fathers, with residential fathers more likely to be in a committed but less satisfactory relationship regardless of timing of fatherhood. Nonresidential fathers were more likely to have close relationships with their mothers and fathers, but findings varied by timing of fatherhood and gender of parent. Implications of these findings are framed in terms of young men's developmental readiness for multiple demands of first-time fatherhood.

YOUNG ENTREPRENEURS IN THE COUNTRY – STIMULANTS AND BARRIERS

Full Text Available The purpose of this article is, starting from the definition of entrepreneurship, to draw attention to the factors promoting and impeding the development of entrepreneurship of young people in rural areas. This is a category of rural residents, who could play a significant role in the multi-purpose rural development. However, there are few studies that provide data on young entrepreneurs, and information on opportunities and activities for the development of entrepreneurial qualities and attitudes among young people, especially in rural areas. Opportunities and constraints for the development of young entrepreneurship in rural areas are the starting point for the formulation of research problems concerning the entrepreneurial potential of young rural residents.

Factors Contributing to Crashes among Young Drivers

Full Text Available Young drivers are the group of drivers most likely to crash. There are a number of factors that contribute to the high crash risk experienced by these drivers. While some of these factors are intrinsic to the young driver, such as their age, gender or driving skill, others relate to social factors and when and how often they drive. This article reviews the factors that affect the risk of young drivers crashing to enable a fuller understanding of why this risk is so high in order to assist in developing effective countermeasures.

2017-07-01

Among the multiple risk factors, the emergence of conduct problems in young children may be linked to harsh parenting and child's temperamental difficulties, leading to a reciprocal early discordant relationship. Little is known about the characteristics of early parent-child interactions in young children with physical aggression. The purpose of the current study was to evaluate the characteristics of mother-child interactions in dyads referred for excessive physical aggression in young children under 5 years of age compared to mother-child interactions in typically developing young children. Mother-child interactions were assessed during a free-play session in both a clinical sample ( N = 70, child mean age  = 3.5 years) and a nonclinical sample ( N = 80, child mean age  = 3.5 years) by using the Rating Scale of Interaction Style (Clark and Seifer, adapted by Molitor and Mayes). Significant differences were found between several interactive features in clinical and nonclinical dyads. In clinical dyads, mothers' behaviors were often characterized by intrusiveness and criticism toward children, and poor facilitative positioning. Children with excessive aggressive behavior often displayed poor communication, initiation of bids, and poor responsiveness toward the mother. They displayed fewer sustained bouts of play than typically developing children did. In clinical dyads, strong positive correlations were found between child responsiveness and maternal interest in engagement ( r = .41, p children with excessive aggressive behavior develop disrupted mother-infant interactions from a very young age. Several negative interactive features and correlations between child behavior and maternal behavior were found in clinical samples. The effects of these features add up and probably strengthen each other, thus leading to interactive difficulties from a very young age. More attention should be paid to early parent-child interactions in case of

Young adults with acute lymphoblastic leukemia are a distinctive category of patients, with substantial difference in disease biology and response to therapy; hence, they pose unique challenges and issues beyond those faced by children and older adults. Despite inferior survival compared to children, there is growing evidence to suggest that young adults have improved outcomes when treated with pediatric-based approaches. With better supportive care and toxicity management and multidisciplinary team and approach, we have made great improvement in outcomes of young adults with ALL. However, despite significant progress, patients with persistence of minimal residual disease have a poor prognosis. This review discusses current controversies in the management of young adults with ALL, outcomes following pediatric and adult protocols, and the role of allogeneic stem cell transplantation. We also explore recent advances in disease monitoring and highlight our approach to incorporation of novel therapies in the management of young adults with ALL.

2016-01-01

Although the occurrence of sudden cardiac death (SCD) in a young person is a rare event, it is traumatic and often widely publicized. In recent years, SCD in this population has been increasingly seen as a public health and safety issue. This review presents current knowledge relevant to the epidemiology of SCD and to strategies for prevention, resuscitation and identification of those at greatest risk. Areas of active research and controversy include the development of best practices in screening, risk stratification approaches and post-mortem evaluation, and identification of modifiable barriers to providing better outcomes after resuscitation of young SCD victims. Institution of a national registry of SCD in the young will provide data that will help to answer these questions. PMID:26951821

On Young's (1805) equation and Finn's (2006) 'counterexample'

International Nuclear Information System (INIS)

Shikhmurzaev, Yulii D.

2008-01-01

In 1805, Thomas Young considered the balance of forces acting on the contact line formed at the intersection of a liquid-fluid interface with a solid surface and introduced a macroscopic concept of 'contact angle'. From Young's reasoning it follows that in equilibrium the contact angle is a material property of the liquid/fluid/solid system independent of a particular configuration. Two centuries later, Robert Finn considered a model problem which seems to suggest that there is a fundamental flaw in Young's force diagram and the reasoning behind it. In the present note, we show that the apparent paradox in Finn's model problem disappears once Young's original concepts are applied in a correct way

Hoyt, Michael A; Cano, Stefan J; Saigal, Christopher S; Stanton, Annette L

2013-12-01

Patient-reported outcome instruments are needed to measure health-related quality of life (HRQOL) in young adults with cancer. The purpose of this project was to establish a conceptual model and measurement instrument for assessment of HRQOL in young men with testicular cancer. Patient interviews and a literature review were used to develop a conceptual framework of biopsychosocial domains of cancer-related quality of life and an initial pool of questionnaire items. Items were piloted and refined. Revised items were administered to a sample (N = 171) of young (ages 18-29) men with testicular cancer and repeated 4 weeks later. Rasch measurement methods guided item reduction and scale construction. Traditional psychometric analyses were also performed to allow for comparison with existing measures. The conceptual framework included seven biopsychosocial domains: physical, sexual, intrapersonal, cognitive-emotional, social-relational, educational-vocational-avocational, and spiritual to form independent scales of the resulting questionnaire, the Cancer Assessment for Young Adults-Testicular (CAYA-T). Each scale fulfilled Rasch and traditional psychometric criteria (i.e., person separation index, 0.34-0.82; Cronbach's alpha, 0.70-0.91; and an expected pattern of convergent and discriminant validity correlations). The CAYA-T can be used to assess HRQOL across a comprehensive set of domains as identified by young men with cancer. It passes strict psychometric criteria and has potential as a useful research and clinical tool. The CAYA-T has potential research and clinical value for addressing inter-related aspects of HRQOL in young adult men with cancer. The measure may assist with assessing and monitoring HRQOL across a range of domains and contributing to more comprehensive assessment of biopsychosocial needs of young adults.

Weight comments by family and significant others in young adulthood.

2011-01-01

Weight teasing is common among adolescents, but less is known about the continuation of this experience during young adulthood. The present study uses survey data from a diverse sample of 2287 young adults, who participated in a 10-year longitudinal study of weight-related issues to examine hurtful weight comments by family members or a significant other. Among young adults, 35.9% of females and 22.8% of males reported receiving hurtful weight-related comments by family members, and 21.2% of females and 23.8% of males with a significant other had received hurtful weight-related comments from this source. Hispanic and Asian young adults and overweight/obese young adults were more likely to report receiving comments than those in other groups. Weight teasing during adolescence predicted hurtful weight-related comments in young adulthood, with some differences by gender. Findings suggest that hurtful weight talk continues into young adulthood and is predicted by earlier weight teasing experiences. Copyright © 2010 Elsevier Ltd. All rights reserved.

Overweight and obesity are a major concern in young adults. Technology has been integrated into many weight loss interventions; however little is known about the use of this technology in young adults. The purpose of this study was to explore through focus group sessions the opinions of young adults on the use of technology for weight loss. A total of 17 young adults, between 18 and 25 years of age, participated in three focus group sessions. Major results indicated that young adults have very little knowledge on the use of Smartphone technology for weight loss but would like to use this type of technology to help them lose weight. Results also indicated that young adults struggle to make healthy food choices and have priorities that outweigh exercise and they need support and guidance to make better decisions. In conclusion, young adults would be open to using Smartphone technology for weight loss but also need feedback and guidance to help make healthy decisions.

Prayer is the most common complementary and alternative intervention used by most Americans. Yet, little is known about the prayer practices of young adults. In this exploratory study, 4 types of prayer practices of 62 young adults (21-30 years old) are described. The 4 different categories of prayer were: contemplative-meditative, ritualistic, petitionary, and colloquial. Participants most often used colloquial prayer practice, that is, asking God to provide guidance or talking to God in their own words. Recommendations for future research are included.

Young adult's attachment style as a partial mediator between maternal functioning and young adult offsprings' functioning.

The quality of our early attachment relationships with primary caregivers is carried forward to new developmental domains, including interpersonal contexts in adulthood. One of the factors that can disrupt early attachment is maternal depression, which may be associated with less responsive care and may impede the development of a secure attachment. Moreover, this disruption in secure attachment may act as a mechanism by which offspring of depressed mothers are more likely to experience their own psychopathology. In this study we predicted that attachment anxiety and avoidance would mediate the relationship between maternal depression diagnosis and functional impairment predicting young adult offspring's functional impairment. This study utilized longitudinal data from 98 families with clinically diagnosed depressed and well mothers, and two of their young adult children, an older and younger sibling (N = 123, Female = 75, Mage = 22.09, SD = 2.57). Mother's and young adult children's functioning was based on clinical ratings on the Global Assessment Scale. Attachment was based on the young adult's self-report on the Experiences in Close Relationships. Results indicate that maternal diagnosis and functional impairment predicted offspring's functional impairment. This relationship was partially mediated through offspring's attachment anxiety, but not attachment avoidance. The mediator and outcome variable were measured concurrently, thus causal implications are limited. Our study provides critical evidence that early experiences with depressed mothers may have influence into young adulthood in typical and atypical domains of development. This work extends our understanding of the impact of early experiences in long-term development, and may have treatment implications for intervening on both maternal and romantic relationships to improve attachment.

Young people's time use and maternal employment in the UK.

Science.gov (United States)

Mullan, Killian

2009-12-01

This paper analyses the relationship between young people's time use and maternal employment in the United Kingdom (UK). Two dimensions of young people's time use are important for understanding the impact of maternal employment. The first of these is family context. This concerns the time young people are near their parents or not. The second relates to young people's activity patterns. Combining information from both dimensions is necessary to provide a comprehensive overview of the impact of maternal employment on young people's time use. The paper demonstrates that young people's time use is associated with maternal employment both in terms of activity patterns and family context. Young people with employed mothers spend more time alone with a father, and more time with neither parent. More specifically, young people with mothers employed full time (FT) spend significantly more time watching TV than those whose mothers are not employed, especially when they are not near any parents. There is a negative association between FT maternal employment and the time young people spend in achievement-related activities, concentrated in time when alone with a mother. Unlike time in leisure activities or time watching TV, time in achievement-related activities when in the presence of a father does not increase to compensate for the loss in time spent in achievement-related activities when alone with a mother.

Full Text Available The injuries in young athletes are becoming more frequent, due to the wade dissemination of sports and the excessive training aimed at high performance. The requirements in sports can lead to the development of pathologies and injuries that could be prevented if the young athlete's training was well oriented. We emphasize the importance of professional and competition calendar planning always seeking the recovery of the athlete. It’s also important to have knowledge of injuries, training load, the previous history of the athlete, and correction of improper movement technique.Objective: To identify the most common injuries in young athletes of different sports. Material and Methods: The study included 36 athletes, aged 12-17 years, of both sexes, the Athletics rules, futsal, swimming and volleyball. An interview that contained information about age, practice time and sport was initially applied. Then two questionnaires were applied, the first consisting of a pain distribution table by body region and the second by a pain scale and this interference in daily activities. Results:Obtained results as mean age 13.86 years. Among the participants, 66.7% reported practicing sports or other physical activities, 55.6% reported that they have suffered injury in some cases with recurrence and 50% who have had any treatment for pain.Conclusion: Based on the results we conclude the importance of knowledge about sports injury prevention strategies in young athletes as a way to ensure longevity in the sport.

Breast cancer in young women.

Radecka, Barbara; Litwiniuk, Maria

Breast cancer (BC) in young women is rare, affecting only 4-6% of women under the age of 40. Regardless, BC remains the most common malignancy among younger patients. Recently, a significant increase in BC rates has been observed among pre-menopausal subjects. Breast cancer in young women requires special attention due to its specific morphologic and prognostic characteristics and unique aspects, including fertility preservation and psychosocial issues (e.g. its impact on family life and career). Young women are more likely to have tumors with higher incidence of negative clinicopathologic features (higher histological grade, more lymph node positivity, lower estrogen receptor (ER) positivity, higher rates of Her2/neu overexpression). Also, they tend to be diagnosed at more advanced stages of the disease. That, in turn, contributes to less favorable prognosis as compared to older women. Young women are generally treated similarly to older patients. Surgical management includes mastectomy or breast-conserving surgery, followed by radiation therapy (younger women have higher local recurrence rates than older women, especially after breast-conserving therapy). Although the basics of chemotherapy are the same for patients of all ages, younger women have some special considerations. It is important to consider options for fertility preservation before starting systemic treatment. Patients should have access to genetic testing as their results may affect the choice of therapy. Younger women and their families should receive adequate psychological support and counselling.

2017-12-01

Sixty-three percent of cancer survivors continue to work, or return to work after treatment. Among this population, work ability and challenges encountered in the workplace by young adult cancer survivors have not been well established. The purposes of the study are to describe what is currently known about work-related issues for young adult cancer survivors diagnosed between ages 15 and 39, to identify gaps in the research literature, and to suggest interventions or improvements in work processes and occupational settings. A narrative review of articles using PubMed, CINAHL, and PsychInfo was conducted without date limitations. Search phrases included young adult cancer survivors, long-term cancer survivors, young adults affected by cancer, further combined with key terms employment, work, and occupationally active. Inclusion criteria for publications were young adult cancer survivors initially diagnosed between the ages of 15 and 39, data about work or employment was presented, and articles written in English. Twenty-three publications met the inclusion criteria. Work-related issues included the potential for reduced work productivity from cancer-changed physical and cognitive functional ability that affected income, and resulted in distress. Coping style, support systems, and changing perspectives about work and life in general were also influential on career decisions among young adult cancer survivors. More research is needed to study interventions to better manage health changes in young adult cancer survivors within the context of the workplace. Since financial hardship has been shown to be especially high among young cancer survivors, employment is essential to ensure payment of cancer-associated costs and continued medical care. While young adult cancer survivors may initially grapple with cancer-related physical and psychosocial changes that impact work productivity or influence choice of occupation, employment appears to enhance overall quality of life.

Compared to a large body of work on how gender may affect young women's vulnerability to HIV, we know little about how masculine ideals and practices relating to marriage and fertility desires shape young men's HIV risk. Using life-history interview data with 30 HIV-positive and HIV-negative young men aged 15-24 years, this analysis offers an in-depth perspective on young men's transition through adolescence, the desire for fatherhood and experience of sexual partnerships in rural Uganda. Young men consistently reported the desire for fatherhood as a cornerstone of masculinity and transition to adulthood. Ideally young men wanted children within socially sanctioned unions. Yet, most young men were unable to realise their marital intentions. Gendered expectations to be economic providers combined with structural constraints, such as limited access to educational and income-generating opportunities, led some young men to engage in a variety of HIV-risk behaviours. Multiple partnerships and limited condom use were at times an attempt by some young men to attain some part of their aspirations related to fatherhood and marriage. Our findings suggest that young men possess relationship and parenthood aspirations that - in an environment of economic scarcity - may influence HIV-related risk.

Full Text Available According to a recent study entitled, ”Professional Status of Young Journalists in the Autonomous Province of Vojvodina”, the primary complaints of journalists thirty-years old and younger are overtime,small salaries, uneducated executives, censorship, and the infl uence of politics and advertisers on editorial policy. Most of the interviewees are not permanently employed, receiving some 200€ honoraria,and as they have mentioned, executives and editors do not suffi ciently trust them, nor are they aff orded adequate space to express themselves. While Serbia has enacted nominal steps toward democracy over the past ten years, and in the process has reduced the number of persecutions and arrests of journalists and punishments and cancellations of media, more than half of the young journalists surveyed have experienced restraints in freedom of speech while doing their job. Further, ten percent of those surveyed state that they are often censored. The basis of this examination emanates from research on the professional status of ”eternal freelancers”, conducted in 2009 by the Youth Development Fund (Razvojni fond za mlade – RFM expert team, with the support from the Provincial Secretariat for Sport and Youth. In addition, a questionnaire has been filled out by over 50 young journalists from Vojvodina.

Our multicultural island community is unique in that many young mothers live in multigenerational households. In this qualitative study, we examined the factors that influenced young mothers' infant-feeding practices in Hilo, a small rural town in the Hawaiian Islands. The study participants consisted of young mothers, health care professionals, and educators. Our findings suggest that both the young mother's mother and her partner are very influential in the infant-feeding decision. Many young women in our study bottle fed to obtain assistance in caretaking, and to facilitate public breastfeeding. Additionally, we explored young mother's views of sexuality and breastfeeding, and their health promotion implications.

Life Strategies of Young People: Sociological Research Experience

Directory of Open Access Journals (Sweden)

Lyubov’ Borisovna Osipova

2016-09-01

Full Text Available Modern reality is the world of formation of various life prospects of a young person. The relevance of the topic depends, firstly, on insufficient sociological research into the mechanism of formation and realization of life strategies of modern youth; and, secondly, on the need to substantiate the sociological concept of youth life strategies in terms of professional self-determination with regard to its social and group characteristics. In this context, young people as the most active social group are of great interest to the authors who consider them a research target. Due to the transitivity of a social status and the incomplete processes of social maturity formation young people need a targeted design of their future. The sociological analysis of the issue involves a clarification of the concept of “life strategy” at the conceptual level (A.A. Volokitin, S.N. Ikonnikova, E.I. Golovakha, Yu.A. Zubok, V.T. Lisovsky, M.N. Rutkevich, G.V. Leonidova, K.A. Ustinova, etc.. The article presents the author’s definition of “life strategies”, which is a dynamic system of perspective individual orientation aimed at designing one’s life in the future. At the same time the results of the author’s sociological research are presented, including a standardized interview, questionnaires, which provide an opportunity to form an idea about the living choices of young people living in Yugra. The declining influence of social institutions and the emerging opportunities for developing their life prospects on their own challenges young people to select their life targets and ways of their implementation independently. The article justifies the necessity of intensified activation of new forms of young students’ management when planning their life trajectory. Life strategies disclose its content in specific life situations associated with choice. The key choice is the career choice of young people which directly depends on the socio

Thomas, Tami L; Stephens, Dionne P; Johnson-Mallard, Versie; Higgins, Melinda

2016-03-01

This exploratory descriptive study examined perceived vulnerabilities to human papillomavirus (HPV) and the correlation to factors influencing vaccine beliefs and vaccine decision making in young Hispanic males attending a large public urban university. Only 24% of participants believed that the HPV vaccine could prevent future problems, and 53% said they would not be vaccinated. The best predictors of HPV vaccination in young Hispanic men were agreement with doctor recommendations and belief in the vaccine's efficacy. Machismo cultural norms influence young Hispanic men's HPV-related decision making, their perceptions of the vaccine, and how they attitudinally act on what little HPV information they have access to. This study provides culturally relevant information for the development of targeted health education strategies aimed at increasing HPV vaccination in young Hispanic men. © The Author(s) 2014.

Park, M Jane; Scott, Jazmyn T; Adams, Sally H; Brindis, Claire D; Irwin, Charles E

2014-07-01

Adolescence and young adulthood are unique developmental periods that present opportunities and challenges for improving health. Health at this age can affect health throughout the lifespan. This review has two aims: (1) to examine trends in key indicators in outcomes, behaviors, and health care over the past decade for U.S. adolescents and young adults; and (2) to compare U.S. adolescents and young adults on these indicators. The review also assesses sociodemographic differences in trends and current indicators. Guided by our aims, previous reviews, and national priorities, the present review identified 21 sources of nationally representative data to examine trends in 53 areas and comparisons of adolescents and young adults in 42 areas. Most health and health care indicators have changed little over the past decade. Encouraging exceptions were found for adolescents and young adults in unintentional injury, assault, and tobacco use, and, for adolescents, in sexual/reproductive health. Trends in violence and chronic disease and related behaviors were mixed. Review of current indicators demonstrates that young adulthood continues to entail greater risk and worse outcomes than adolescence. Young adults fared worse on about two-thirds of the indicators examined. Differences among sociodemographic subgroups persisted for both trends and current indicators.

Vizgin, Vladimir P

2001-01-01

This article describes the history of discovery of the equations of gravitational field by Albert Einstein and David Hilbert in November 1915. The proof sheet of Hilbert's lecture report, made on 20 November 1915 and published in March 1916, rediscovered in 1997 in the archive of the university of Goettingen, throws new light on the history of this discovery. We also discuss the early history of the general theory of relativity that led to the expression of the general covariant equations of gravitational field. (from the history of physics)

The relationship between maternal attitudes and young people's attitudes toward children's rights.

Science.gov (United States)

Day, David M; Peterson-Badali, Michele; Ruck, Martin D

2006-04-01

Relations between maternal socio-political attitudes and parenting style and young people's and mothers' attitudes toward young people's nurturance and self-determination rights were examined. Both young people (n = 121) and mothers (n = 67) were more supportive of nurturance than self-determination rights, although young people were more supportive than their mothers of self-determination rights and mothers were more supportive than young people of nurturance rights. Maternal conservatism was unrelated to young people's support for rights and negatively related to mothers' support for both types of rights. Last, young people who perceived their mother to be either authoritarian or uninvolved showed stronger endorsement of self-determination rights than young people who perceived their mother to be authoritative. The implications of these findings for the development of young people's attitudes toward rights within the context of various family factors are discussed. In particular, it is suggested that a balance needs to be achieved between assertion of rights and a respect for the rights of others.

2013-01-01

Lexical fluency tests are frequently used in clinical practice to assess language and executive function. As part of the Spanish normative studies project in young adults (NEURONORMA young adults project), we provide age- and education-adjusted normative data for 3 semantic fluency tasks (animals, fruits and vegetables, and kitchen tools), three formal lexical fluency tasks (words beginning with P, M and R), three excluded-letter fluency tasks (words excluding A, E and S) and a verb fluency task. The sample consisted of 179 participants who are cognitively normal and range in age from 18 to 49 years. Tables are provided to convert raw scores to scaled scores. Age- and education-adjusted scores are provided by applying linear regression techniques. The results show that education impacted most of the verbal fluency test scores, with no effects related to age and only minimal effects related to sex. The norms obtained will be extremely useful in the clinical evaluation of young Spanish adults. Copyright © 2011 Sociedad Española de Neurología. Published by Elsevier Espana. All rights reserved.

Health promotion and young prisoners: a European perspective.

MacDonald, Morag; Rabiee, Fatemeh; Weilandt, Caren

2013-01-01

The purpose of this paper is to assess the health promotion needs of vulnerable young prisoners and the existing health promotion activities in custodial settings in seven European Union (EU) Member States. The research comprised two components: the first involved identifying existing health promotion practices. The second involved mapping out young offenders' health promotion needs by carrying out a needs assessment. Both quantitative and qualitative methods were adopted. The quantitative element comprised surveys among young prisoners and prison staff and focused on the availability and perceived importance of health promotion activities in prison. The qualitative element comprised focus groups with young offenders and individual interviews with prison staff, field experts and NGO members. The findings from the research have identified a number of similar, but also some diverse areas of unmet need for health promotion activities in prison settings across these diverse seven EU countries. There is no consistency of approach within and between countries regarding health promotion policy, guidance, resources and programmes for young prisoners. In order to improve the health of young prisoners and to establish and increase sustainability of existing health promotion programmes, there is a need for the establishment of National and EU standards. Providing health promotion activities for young prisoners while in custodial settings is key to addressing their unmet health and well-being needs and to facilitate their reintegration back into the community. Despite the barriers identified by this research, health promotion is to some extent being delivered in the partner countries and provides a foundation upon which further implementation of health promotion activities can be built especially when the benefits of health promotion activities, like dealing with the common problems of alcohol and drug addiction, mental health and communicable diseases are linked to successful

Does adolescent gambling co-occur with young fatherhood?

Lee, Grace P; Storr, Carla L; Ialongo, Nicholas S; Martins, Silvia S

2013-01-01

Young fatherhood is associated with various adverse outcomes. This study aims to describe the relationship of adolescent gambling with young fatherhood (by age 20) while adjusting for several young fatherhood antecedents. Data were from 294 males who have been followed for 16 years since entering first grade in nine inner city public schools (86% African Americans, 81% of the original male cohort). Self-reports of impregnation (including age) and gambling were collected during late adolescence. Nelson-Aalen curves and Cox regression models assessed the hazard of young fatherhood among adolescent nongamblers, social gamblers, and problem gamblers. More young fathers than nonfathers reported adolescent social (49.2% vs. 42.5%) and problem gambling (28.3% vs. 13.2%, p fatherhood, followed by social gambling (aHR = 1.95, 95% CI = 1.30, 2.94, p = .001), high school dropout (aHR = 1.75, 95% CI = 1.14, 2.70, p = .01), and subsidized lunch status (aHR = 1.69, 95% CI = 1.01, 2.38, p = .04). Adolescent male gamblers, particularly problem gamblers, were more likely than their nongambling peers to become fathers by the age of 20. Such a result shows that there is a subpopulation of males who are at high risk for adverse outcomes such as young parenthood and problem behaviors. Only through further studies could the needs of this subpopulation be better assessed so that appropriate assistance could be delivered to better the lives of such individuals.

Lee, H. R.; Lee, Y. H.; Kim, K. W.

1985-01-01

Carcinoma of the stomach is usually considered a disease of middle aged or elderly patients and is rarely suspected in young adults. However carcinoma of the stomach in the young adults is an aggressive malignant disease with nonspecific symptoms and worse prognosis than older age group because of late diagnosis and increased incidence of undifferentiated form. In an attempt to identify further the natural history of carcinoma of the stomach in the young adults, we reviewed 68 cases of stomach cancers in patients 30 years of age and less at Severance hospital. The results were as follows: 1. The over-all male to female ratio in the young adult was 1:1.34 and in order age group was 2.44:1. 2. Common symptoms included epigastric pain, weight loss and vomiting. The mean time interval between onset of symptoms and the first visit to a physician was 3 months. 3. Usually diagnostic aids were UGI series and endoscopic examination. 38 patients underwent an exploratory laparatomy, and lesions were amenable to curative or palliative resection. 4. In the young age Bormann type III and IV were predominant, while in the older age group Bormann type II and III were common. 5. The majority of tumors occurred in the cardia, fundus and upper body. 6. Histologic diagnosis were poorly differentiated adenocarcinoma, signet ring cell carcinoma and anaplastic carcinoma in orders. 7. A relatively high incidence of pregnancy and Krukenberg tumor in the young age were noted

"The little squealer" or "the virtual guardian angel"? Young drivers' and their parents' perspective on using a driver monitoring technology and its implications for parent-young driver communication.

Science.gov (United States)

Guttman, Nurit; Gesser-Edelsburg, Anat

2011-02-01

In-vehicle driving monitoring technologies have the potential to enable young drivers to learn from self-assessment. However, their use is largely dependent on parental involvement. A total of 79 interviews were conducted with young drivers and parents regarding this technology and its use. Most had the experience of having an in-vehicle data recorder installed in the vehicle driven by the young drivers. Parents and the young drivers expressed both appreciation as well as reservations about its potential as a means to enhance the driving safety of young drivers. A surprising finding was that some parents did not check the feedback and said they relied on the young driver to do so. Main concerns related to privacy, parent-young driver relationship, self-esteem and confidence, constructive use of the feedback data, and the limitations of the documentation that can be done by the technology. Providing parents and young drivers with a support system and tools to discuss and utilize the feedback are underscored. Challenges include addressing the invasion of young drivers' privacy and gender differences, and using the monitoring-capacity of the technology to enhance safe driving practices. Implications for programs to enhance communication and a dialogical approach between parents and young drivers are discussed. Copyright © 2010 Elsevier Ltd. All rights reserved.

Noor-Eesti antifuturismist.On the Anti-Futurism of Young Estonia

Virve Sarapik

2012-04-01

Full Text Available Young Estonia persists in Estonian cultural memory as a movement of renewal, among other factors through its impetus to the development of urban culture. This article undertakes to juxtapose Young Estonia’s efforts at cultural renewal, its rhetoric of the future, and futurism as a cultural phenomenon. (As such, futurism was vitally engaged with contemporary urban culture, industry, and technology. Four parameters serve as points of departure: (1 Young Estonia’s rhetoric of the new and the future. Though specific about what they rejected, Young Estonia’s texts do not outline a clear vision of the future. Frequently used key words for what they opposed included German- or Russian-mindedness, a people in servitude, the old, flat land, the lack of a unified whole, lack of style. (2 The place of the city in Young Estonia’s texts. Though in earlier publications there were only a few passing references to urban culture, the problems of the city come to the fore in several programmatic texts and in the visual design of the fourth Young Estonia album in 1912. By then the core members of Young Estonia also had had real experience of a large metropolis. If their earlier attitude toward the city had been critical, then in these Young Estonian texts the city finds its positive face. (3 Industry and the proletariat. The Young Estonia movement received stimulus from such general phenomena as factories, technology, and industry. In their imagination working people and educated people seem to live in separate worlds, with different wishes and needs. However, the freedom of the educated would be impossible without political freedom. Although they believed that technological development was a precondition for the creation of urban culture, neither their own literary works nor their other aspirations bore this out. (4 Futurism and film. Young Estonia’s later period coincided with the intensive use of term ”futurism” in Estonian journalism. Young

The Health Consequences of Obesity in Young Adulthood.

Science.gov (United States)

Cheng, Hoi Lun; Medlow, Sharon; Steinbeck, Katharine

2016-03-01

Young adults are gaining weight faster than any age group. This weight gain and the appearance of obesity-related comorbidities often commence in adolescence. Psychosocial distress and mental health issues are common and debilitating, and treatment approaches are likely to be similar to those for adolescents. At the same time, young adults may have physical morbidities which will continue and worsen throughout adulthood, such as hypertension, diabetes and polycystic ovarian syndrome. Health consequences of obesity are challenging to manage in young adults as their symptoms may be minimal, they are less likely to engage with healthcare due to other life priorities and their neurocognitive developmental stage makes therapy adherence difficult. Clinicians who manage young adults with obesity need to be aware of these age-specific challenges, as well as the sexual and reproductive health concerns that are present in this age group.

Marriage Matters But How Much? Marital Centrality Among Young Adults.

Willoughby, Brian J; Hall, Scott S; Goff, Saige

2015-01-01

Marriage, once a gateway to adulthood, is no longer as widely considered a requirement for achieving adult status. With declining marriage rates and delayed marital transitions, some have wondered whether current young adults have rejected the traditional notion of marriage. Utilizing a sample of 571 young adults, the present study explored how marital centrality (the expected importance to be placed on the marital role relative to other adult roles) functioned as a unique and previously unexplored marital belief among young adults. Results suggested that marriage remains an important role for many young adults. On average, young adults expected that marriage would be more important to their life than parenting, careers, or leisure activities. Marital centrality profiles were found to significantly differ based on both gender and religiosity. Marital centrality was also associated with various outcomes including binge-drinking and sexual activity. Specifically, the more central marriage was expected to be, the less young adults engaged in risk-taking or sexual behaviors.

perkembangan dan usia kronologis pemustaka. Kata Kunci: fiksi remaja terjemahan, pengembangan koleksi fiksi, perkembangan remaja, Pitimoss Fun Library Abstract. Library has to provide fiction as one of its collection. There are two kind of fictions; national fiction and translated fiction. Its selection is not only based on amusement function, but also its role to help readers developing themselves. This research aims to describe the roles of translated young adult fiction in achievement of three aspects of young adult development. Those aspects are cognitive, social, and affective. Theoritically, this research gives advantages for library and information science, especially for developing selection theory and bibliotheraphy. Practically, the advantages those are given by this research are tended to caretakers of Pitimoss Fun Library and other researchers. This reasearch is done by using qualitative approach.Meanwhile, descriptive method is chosen with case study interpretative as its model. The answers of research questions are based on explanation of six informants and key informant. Six informants are chosen by purposive sampling technique. Meanwhile, key informant is a bibliotheraphist. Observation, interview, document study, and  online searching are techniques those are used for collecting data. Research data are analyzed by narrative analysis technique. The result shows the two-way relation between translated young adult fiction and developmental achievement. Translated young adult fictions those are provided by Pitimoss Library have roles in achievement of three aspects of young adult development. Even so, developmental achievement also determines the effectiveness of translated fiction roles for young adults. It also helps them to react to controversial issues. The roles of translated young adult fiction can be maximized if Pitimoss Fun Library doing some efforts, such us involving developmental needs as one of selection criteria, also giving guidance and books

Perceptions of sexual coercion among young women in Uganda.

Science.gov (United States)

Hayer, Manvir Kaur

2010-01-01

This paper sets out to explore Ugandan young women's definitions and perceptions of sexual coercion. A qualitative study was conducted with seven young women in rural Uganda. Participants filmed videos, wrote stories, made drawings and participated in transect walks before analysing their data through formal and informal discussions. Forced sex is defined narrowly to mean only rape. Verbal forms of sexual coercion were recognised, but only after some discussion. Verbal coercion is referred to as "abusing" or "convincing". Young women are commonly pressured into consenting to have sex, despite what they really want, owing to the socio-cultural circumstances. Young women in Uganda are significantly tolerant of sexual coercion. This tolerance appears to arise from power differentials between genders, and the socio-cultural environment shaping their lives. The paper improves understanding of young women's definitions and perceptions of sexual coercion, which is essential to provide effective violence prevention programmes. It also suggests that further research is warranted in this field.

WORKING WITH YOUNG PEOPLE: A MODEL OF SOCIAL INTERVENTION

Full Text Available Social workers, working with young people ought to be aware of the values, needs and problems of contemporary young people. Therefore, it is necessary to develop study programmes of Social Work that would reflect the current situation of modern youth and be oriented towards effective techniques for working with young people. The most common methods described in the literature are counseling, supervision, case management, self-reflection. The article highlights the method of social intervention, which objectively and fully assesses the problem situation and establishes the connections and relationships between the young man and his relatives, friends or authorities. This method helps to enable young people to solve their own problems. The aim of the research is to analyze the application features of the social intervention model when working with young people. The objectives are to discuss the activities of youth organizations in the field of social 99SOCIALINIO TINKLO INTERVENCIJOS MODELIO TAIKYMAS DIRBANT SU JAUNIMU work; to highlight the methods of social workers‘ practice; to investigate the application of social intervention model, enabling young people to solve their own problems. The methods applied include comparative analysis of scientific literature, monitoring, social intervention model. The survey revealed that when social workers enable young people to solve their own problems, a model of social intervention allows to evaluate not only the relationships of close people or family members, but also highlights the roles of youth organizations or social workers and their positive effect on the customer‘s actions. Thus, when applying the method of social intervention, social workers play an important role, as well as their professional knowledge and skills to establish the connection with the client are extremely important in order to promote the client‘s reflection.

'Not the swab!' Young men's experiences with STI testing.

Science.gov (United States)

Shoveller, Jean A; Knight, Rod; Johnson, Joy; Oliffe, John L; Goldenberg, Shira

2010-01-01

In Canada, STI rates are high and rising, especially amongst young men. Meanwhile, the needs of young men regarding STI testing services are poorly understood, as are the socio-cultural and structural factors that influence young men's sexual health-seeking behaviours. To better understand this phenomenon, we draw on interviews with 45 men (ages 15-25) from British Columbia, Canada. Our research reveals how structural forces (e.g. STI testing procedures) interact with socio-cultural factors (e.g. perceptions of masculinities and feminities) to shape young men's experiences with STI testing. STI testing was characterised as both a potentially sexualised experience (e.g. fears of getting an erection during genital examinations), and as a process where young men experience multiple vulnerabilities associated with exposing the male body in clinical service sites. In response, participants drew on dominant ideals of masculinity to reaffirm their predominately hetero-normative gender identities. Despite growing up in an era where sexual health promotion efforts have been undertaken, participants did not feel they had permission to engage in discussions with other men about sexual health issues. Attending to young men's perspectives on STI testing represents a starting point in reforming our approaches to addressing how socio-cultural and structural factors shape these experiences.

Mapping brain development during childhood, adolescence and young adulthood

Guo, Xiaojuan; Jin, Zhen; Chen, Kewei; Peng, Danling; Li, Yao

2009-02-01

Using optimized voxel-based morphometry (VBM), this study systematically investigated the differences and similarities of brain structural changes during the early three developmental periods of human lives: childhood, adolescence and young adulthood. These brain changes were discussed in relationship to the corresponding cognitive function development during these three periods. Magnetic Resonance Imaging (MRI) data from 158 Chinese healthy children, adolescents and young adults, aged 7.26 to 22.80 years old, were included in this study. Using the customized brain template together with the gray matter/white matter/cerebrospinal fluid prior probability maps, we found that there were more age-related positive changes in the frontal lobe, less in hippocampus and amygdala during childhood, but more in bilateral hippocampus and amygdala and left fusiform gyrus during adolescence and young adulthood. There were more age-related negative changes near to central sulcus during childhood, but these changes extended to the frontal and parietal lobes, mainly in the parietal lobe, during adolescence and young adulthood, and more in the prefrontal lobe during young adulthood. So gray matter volume in the parietal lobe significantly decreased from childhood and continued to decrease till young adulthood. These findings may aid in understanding the age-related differences in cognitive function.

The clinicopathological features and prognosis of gastric cancer in young patients are both limited and controversial. Therefore, the aim of this study was to define the clinicopathological features and prognosis of gastric cancer in young patients after curative resection. From May 2008 to December 2014, 198 young patients (age ≤ 40 years) and 1096 middle-aged patients (55 ≤ age ≤ 64 years) were enrolled in this study. The clinicopathological features and prognosis of gastric cancer in these patients were analyzed. Compared with middle-aged patients, the proportion of females, lower third tumors, tumor size less than 5 cm, poorly differentiated tumors and T1 tumors were significantly higher in young patients (all P < 0.05). The proportions of comorbidity, upper third tumors, well and moderately differentiated tumors, T4 tumors, and positive carcinoembryonic antigen (CEA), alpha fetoprotein (AFP) and carbohydrate antigen (CA) 19–9 were significantly lower in young patients (all P < 0.05). The distributions of N status and CA125 were comparable between young and middle-aged patients (all P > 0.05). The five-year overall survival rates were comparable between young patients and middle-aged patients (62.8 vs 54.7 %, P = 0.307). The tumor location, T status, N status and CA125 were independent predictors of prognosis in young patients. The overall survival of patients with tumors located in the upper or middle third was significantly lower than for those located in the lower third (60.8 vs 50.6 % vs 68.4 %, P = 0.016). The overall survival of CA125-positive patients was significantly lower than CA125-negative patients (49.0 vs 64.4 %, P = 0.001). The clinicopathological features were significantly different between young and middle-aged patients. The prognosis of gastric cancer in young patients was equivalent to that of middle-aged patients. Tumor location, T status, N status and CA125 were independent risk factors for prognosis in young patients. The online

Consequences of Fatherhood for Young Men’s Relationships

2010-01-01

This paper examined how the onset and timing of the transition to fatherhood affects the type and quality of young men’s relationships with partners and parents. Data are drawn from the 1979 National Longitudinal Survey of Youth – Young Adult Survey and included young men (ages 18–31 years old in 2006) who varied on residential status with their children and timing of fatherhood (N = 1,931). Results indicated the effects of fatherhood varied across types of fathers, with residential fathers more likely to be in a committed but less satisfactory relationship regardless of timing of fatherhood. Nonresidential fathers were more likely to have close relationships with their mothers and fathers, but findings varied by timing of fatherhood and gender of parent. Implications of these findings are framed in terms of young men’s developmental readiness for multiple demands of first-time fatherhood. PMID:20640224

A young people's perspective on computer game addiction

DEFF Research Database (Denmark)

Brus, Anne Birgitte

2013-01-01

In this paper I examine computer game addiction as a social phenomenon, analyzing the consequences of using the term in order to express a concern about high frequency consumption or even a problematic usage of computer games. I argue that while it is obviously very important to take seriously...... these concerns about young people ‘at risk’, there is a gap between the phenomenon as a suggested psychiatric diagnosis and young people’s reflections on the matter. Following the work of Goffman and Becker, computer game addiction is not necessarily something negative in the eyes of the player and other young...... people. It is shown that the classification can be a positive element in young people’s identity work. On the other hand, a high consumption of computer games is also considered as ‘culturally unacceptable’. From this perspective, computer game addiction becomes a question of how to construct...

Chamberlain, Samuel R; Derbyshire, Katherine L; Leppink, Eric; Grant, Jon E

2015-10-01

Obesity is one of the leading causes of preventable morbidity and mortality, and young people are increasingly affected. The aim of this study was to examine relationships between obesity and dissociable forms of impulsivity in young adults. A group of young adults (511) was recruited from city areas in the United States using media advertisements. These young adults were administered careful and extensive clinical and neurocognitive assessment in order to quantify different aspects of impulsivity (behavioral/phenomenological-, cognitive-, and personality-related measures). Associations between obesity and impulsivity were explored using multivariate analysis of variance and discriminant function analysis. 10.8% of the sample was obese, and 21.5% was overweight. Compared to controls, subjects with obesity showed significantly elevated rates of maladaptive gambling behaviors, monetary amounts lost to gambling, nicotine consumption, impulsive action (prolonged stop-signal reaction times in the Stop-Signal Test), and impulsive decision-making (reduced modulation of behavior as a function of risk in the Cambridge Gamble Test). Even accounting for potential confounding variables, obesity was significantly predicted by female gender, older age, more maladaptive gambling behaviors, and worse inhibitory control (stop-signal reaction times). Obesity is associated with several dissociable forms of impulsivity in young people, especially gambling and impulse dyscontrol. Family doctors should screen for gambling problems in obese young adults. Successful treatment of nicotine dependence in young obese people is likely to require intensive weight management support. Neuropsychological deficits relating to impulsivity occur in obese people in early adulthood, and may represent vulnerability markers rather than being due to chronic untoward metabolic effects on brain function.

Ischaemic stroke (IS) in young adults has been increasingly recognized as a serious health condition. Stroke aetiology is different in young adults than in the older population. This study aimed to investigate aetiology and risk factors, and to search for predictors of outcome and recurrence in young IS patients. We conducted a prospective multicentre study of consecutive IS patients aged 16-55 years. Baseline demographic data, risk factors, stroke aetiology including systematic genetic screening for Fabry disease and severity were assessed and related to functional neurological outcome (modified Rankin Scale, mRS), case fatality, employment status, place of residence, and recurrent cerebrovascular events at 3 months. In 624 IS patients (60% men), median age was 46 (IQR 39-51) years and median NIHSS on admission 3 (IQR 1-8). Modifiable vascular risk factors were found in 73%. Stroke aetiology was mostly cardioembolism (32%) and of other defined origin (24%), including cervicocerebral artery dissection (17%). Fabry disease was diagnosed in 2 patients (0.3%). Aetiology remained unknown in 20%. Outcome at 3 months was favourable (mRS 0-1) in 61% and fatal in 2.9%. Stroke severity (p young adults with IS had modifiable vascular risk factors, emphasizing the importance of prevention strategies. Outcome was unfavourable in more than a third of patients and was associated with initial stroke severity and diabetes mellitus. Previous cerebrovascular events predicted recurrent ones.

Despite significant progress in primary prevention, the rate of MI has not declined in young adults. The purpose of this study was to evaluate statin eligibility based on the 2013 American College of Cardiology/American Heart Association guidelines for treatment of blood cholesterol and 2016 U.S. Preventive Services Task Force recommendations for statin use in primary prevention in a cohort of adults who experienced a first-time myocardial infarction (MI) at a young age. The YOUNG-MI registry is a retrospective cohort from 2 large academic centers, which includes patients who experienced an MI at age ≤50 years. Diagnosis of type 1 MI was adjudicated by study physicians. Pooled cohort risk equations were used to estimate atherosclerotic cardiovascular disease risk score based on data available prior to MI or at the time of presentation. Of 1,685 patients meeting inclusion criteria, 210 (12.5%) were on statin therapy prior to MI and were excluded. Among the remaining 1,475 individuals, the median age was 45 years, there were 294 (20%) women, and 846 (57%) had ST-segment elevation MI. At least 1 cardiovascular risk factor was present in 1,225 (83%) patients. The median 10-year atherosclerotic cardiovascular disease risk score of the cohort was 4.8% (interquartile range: 2.8% to 8.0%). Only 724 (49%) and 430 (29%) would have met criteria for statin eligibility per the 2013 American College of Cardiology/American Heart Association guidelines and 2016 U.S. Preventive Services Task Force recommendations, respectively. This finding was even more pronounced in women, in whom 184 (63%) were not eligible for statins by either guideline, compared with 549 (46%) men (p adults who present with an MI at a young age would not have met current guideline-based treatment thresholds for statin therapy prior to their MI. These findings highlight the need for better risk assessment tools among young adults. Copyright © 2018 American College of Cardiology Foundation. Published by

Hughes, Mary; Savage, Eileen; Andrews, Tom

2018-01-01

The aim of this study was to develop an explanatory theory on the lives of young people with asthma, issues affecting them and the impact of asthma on their day-to-day lives. Accommodating Interruptions is a theory that explains young people's concerns about living with asthma. Although national and international asthma management guidelines exist, it is accepted that the symptom control of asthma among the young people population is poor. This study was undertaken using Classic Grounded Theory. Data were collected through in-depth interviews and clinic consultations with young people aged 11-16 years who had asthma for over 1 year. Data were also collected from participant diaries. Constant comparative analysis, theoretical coding and memo writing were used to develop the substantive theory. The theory explains how young people resolve their main concern of being restricted by Accommodating Interruptions in their lives. They do this by assimilating behaviours in balance finding, moderating influence, fitting in and assuming control minimising the effects of asthma on their everyday lives. The theory of Accommodating Interruptions explains young people's asthma management behaviours in a new way. It allows us to understand how and why young people behave the way they do because they want to participate and be included in everyday activities, events and relationships. The theory adds to the body of knowledge on how young people with asthma live their day-to-day lives and it challenges some existing viewpoints in the literature regarding their behaviours. The findings have implications for developing services to support young people in a more meaningful way as they accommodate the interruptions associated with asthma in their lives. © 2017 John Wiley & Sons Ltd.

Parent--child relations and offending during young adulthood.

Johnson, Wendi L; Giordano, Peggy C; Manning, Wendy D; Longmore, Monica A

2011-07-01

There is a long tradition of studying parent-child relationships and adolescent delinquency. However, the association between parent-child relationships and criminal offending during young adulthood is less well understood. Although the developmental tasks of young adulthood tend to focus on intimate relationships, employment, and family formation, the parent-child bond persists over the life course and likely continues to inform and shape behavior beyond adolescence. Using data from the Toledo Adolescent Relationships Study (TARS), the influence of parental involvement on patterns of offending among respondents interviewed first as adolescents (mean age of 15 years), and later as young adults (mean age of 20 years), is examined. The TARS sample used for our study (N = 1,007) is demographically diverse (49.5% female; 25.3% Black; 7.2% Hispanic) and includes youth beyond those enrolled in college. The influences of both early and later parenting factors such as support, monitoring and conflict on young adults' criminal behavior are examined. Results show that early monitoring and ongoing parental support are associated with lower offending in young adulthood. These effects persist net of peer influence and adolescent delinquency. This suggests the importance of examining multiple ways in which parental resources and support influence early adult behavior and well-being.

Objective: To evaluate the long-term effect of coronary stenting in young coronary artery diseased patients ( 45) undergoing coronary stenting were chosen randomly as the control group. Comparison the general characteristics, coronary angiographies, interventional and follow-up information between the two groups was undertaken. Results: Comparing with the control group, the young group patients presented much more myocardial infarctions (68% vs 35%, P<0.05) and single-vessel disease (83% vs 57%, P=0.001). Complete revascularization was achieved in 95% patients in the young group (95% vs control 78%, P=0.004). With a mean 67 ± 9 months follow-up, recurrent angina and readmission rate were higher in the young group, as well as the incidence of MACE. Repeat CAG revealed much more de novo lesions in the young group (44% vs 11%, P=0.02) and higher rate of re-stenting. Conclusions: Due to the high rate of complete circulatory reconstruction in young patients, the postprocedural events are probably caused by new coronary arterial lesions; therefore coronary stenting should be regarded as the primary choice of treatment.

2018-03-20

Lesbian, gay, bisexual, transgender and queer/questioning (LGBTQ+) young people of colour are exposed to intersecting dynamics of social prejudice and discrimination related to sexuality and gender as well as race/ethnicity. In particular, Latinx-identifying LGBTQ+ young people face unique challenges in their lives, due to cultural stressors that stigmatise expansive gender and sexual identities. While it is crucial to examine the effects of multiple stressors on the well-being of LGBTQ+ young people of colour, this risk-based focus can overshadow the resilient capacities of multiply marginalised groups. Guided by an intersectional minority stress resilience framework, we asked: how do self-identified LGBTQ+ Latinx young adults manage cultural messages of prejudice and discrimination in relation to their health? Findings underscore how LGBTQ+ Latinx young adults established a strong sense of health autonomy to resist cultural stigma related to their intersecting identities. Young people actively educated themselves on health-related concerns, engaged in health-promoting tactics, and practised cultural negativity management to effectively navigate exposure to prejudice and discrimination.

Approximately 15% of all ischemic strokes (IS) occur in young adults and adolescents. To date, only limited prior public health and research efforts have specifically addressed stroke in the young. Early diagnosis remains challenging because of the lack of awareness and the relative infrequency of stroke compared with stroke mimics. Moreover, the causes of IS in the young are heterogeneous and can be relatively uncommon, resulting in uncertainties about diagnostic evaluation and cause-specific management. Emerging data have raised public health concerns about the increasing prevalence of traditional vascular risk factors in young individuals, and their potential role in increasing the risk of IS, stroke recurrence, and poststroke mortality. These issues make it important to formulate and enact strategies to increase both awareness and access to resources for young stroke patients, their caregivers and families, and health care professionals. The American Academy of Neurology recently convened an expert panel to develop a consensus document concerning the recognition, evaluation, and management of IS in young adults and adolescents. The report of the consensus panel is presented herein. PMID:23946297

This study uses a Bourdieusian approach to assess young adults' resources and examines their association with smoking initiation and cessation. Data were drawn from 1450 young adults participating in the Interdisciplinary Study of Inequalities in Smoking, a cohort study in Montreal, Canada. We used logistic regression models to examine the association between young adults' income, education, and peer smoking at baseline and smoking onset and cessation. Young adults where most or all of their friends smoked had greater odds of smoking onset. Young adults that had completed pre-university postsecondary education also had higher odds of smoking onset after controlling for social support, employment status, and lacking money to pay for expenses. Income and the sociodemographic variables age and sex were not associated with smoking onset. Young adults where half of their friends smoked or where most to all of their friends smoked had lowers odds of smoking cessation. Men were more likely to cease smoking than women. Education, income and age were not associated with cessation. Interventions focusing on peer smoking may present promising avenues for tobacco prevention in young adults.

Carless young drivers refers to those drivers aged between 18 and 25 years who have a driver's license but seldom have opportunities to practice their driving skills because they do not have their own cars. Due to China's lower private car ownership, many young drivers become carless young drivers after licensure, and the safety issue associated with them has raised great concern in China. This study aims to provide initial insight into the self-reported driving behaviors and simulated driving performance of Chinese carless young drivers. Thirty-three carless young drivers and 32 young drivers with their own cars (as a comparison group) participated in this study. A modified Driver Behavior Questionnaire (DBQ) with a 4-factor structure (errors, violations, attention lapses, and memory lapses) was used to study carless young drivers' self-reported driving behaviors. A simulated driving experiment using a low-cost, fixed-base driving simulator was conducted to measure their simulated driving performance (errors, violations, attention lapses, driving maintenance, reaction time, and accidents). Self-reported DBQ outcomes showed that carless young drivers reported similar errors, more attention lapses, fewer memory lapses, and significantly fewer violation behaviors relative to young drivers with their own cars, whereas simulated driving results revealed that they committed significantly more errors, attention lapses, and violation behaviors than the comparison group. Carless young drivers had a lower ability to maintain the stability of speed and lane position, drove more cautiously approaching and passing through red traffic lights, and committed more accidents during simulated driving. A tendency to speed was not found among carless young drivers; their average speed and speeding frequency were all much lower than that of the comparison group. Lifetime mileage was the only significant predictor of carless young drivers' self-reported violations, simulated violations

Previous studies indicate that young people who have positive attitudes towards illicit drugs are more inclined to experiment with them. The first aim of our study was to identify the sociodemographic and risk behaviour characteristics of young people (16-24 years) with positive attitudes towards illicit drug use. The second aim was to identify the characteristics of young people with positive attitudes towards illicit drugs among those who had never tried drugs, those who had tried cannabis but no other illicit drugs, and those who regularly used cannabis and/or had tried other illicit drugs. The analysis was based on a population-based survey from 2013 ( N = 3812). Multiple logistic regression was used to analyse the association between sociodemographic and risk behaviour characteristics and positive attitudes towards illicit drugs. Young men had twice the odds of having positive attitudes towards illicit drug use compared with young women (AOR = 2.1). Also, young age, being single, being employed, smoking tobacco, practising unprotected sex, and experimental cannabis use were associated with positive attitudes towards illicit drug use. Finally, use of cannabis at least 10 times during the previous year and/or use of other illicit drugs had the strongest association with positive attitudes to illicit drug use (AOR = 6.0). Young people who have positive attitudes towards illicit drug use are characterized by a broad range of risky behaviours. These findings may help to identify young people at risk of initiating illicit drug use and thereby support the development and implementation of prevention programmes.

Adolescents with perinatal HIV (PHIV) may be at higher risk of anxiety and depression than HIV negative young people. We investigated prevalence of anxiety and depression symptoms in 283 PHIV and 96 HIV-affected (HIV-negative) young people in England recruited into the Adolescents and Adults Living with Perinatal HIV (AALPHI) cohort. We used Hospital Anxiety and Depression Scale (HADS) scores and linear regression investigated predictors of higher (worse) scores.115 (41%) and 29 (30%) PHIV and HIV-affected young people were male, median age was 16 [interquartile range 15,18] and 16 [14,18] years and 241 (85%) and 71 (74%) were black African, respectively. There were no differences in anxiety and depression scores between PHIV and HIV-affected participants. Predictors of higher anxiety scores were a higher number of carers in childhood, speaking a language other than English at home, lower self-esteem, ever thinking life was not worth living and lower social functioning. Predictors of higher depression scores were male sex, death of one/both parents, school exclusion, lower self-esteem and lower social functioning. In conclusion, HIV status was not associated with anxiety or depression scores, but findings highlight the need to identify and support young people at higher risk of anxiety and depression..

Management of sport-related concussion in young athletes.

Patel, Dilip R; Shivdasani, Vandana; Baker, Robert J

2005-01-01

Sport-related head injuries are a common clinical problem. Most head injuries in young athletes are mild traumatic brain injuries or concussions. The highest number of sport-related concussions has been reported in American football. In addition to the well described physical and psychosocial growth, there is ongoing neurocognitive development of the brain during childhood and through adolescence. This developmental process has direct implications in the assessment and management of head injuries in young athletes. Research on the management and long-term outcome following brain injuries in young athletes is limited. Traditionally, the assessment of concussion has been based on clinical history and physical and neurological examination. Increasingly, neuropsychological testing, especially computerised testing, is providing objective measures for the initial assessment and follow-up of young athletes following brain injuries. Numerous guidelines have been published for grading and return to play criteria following concussion; however, none of these have been prospectively validated by research and none are specifically applicable to children and adolescents.

There are factors that uniquely affect young females in sports. The sociologic aspects of female youth sports can be understood from a historical perspective. Athletics have an influence on the development of young girls, from gender identity and sexual orientation to the foundations of self-esteem and moral development. There is a relationship between certain psychopathologic conditions common in girls and athletics, including eating disorders, depression, and anxiety disorders. Although involvement in sports may engender some of these problems, others may be successfully treated through physical exercise.

2010-03-01

Full Text Available This study investigates whether parental marital status affects young adults’ attitudes toward marriage and divorce. There exists a vast amount of literature on the impact of divorce on young adults in Western cultures; however, no previous empirical studies have been conducted on the attitudes of young adults from intact and divorced families in the Gulf region or in Arab countries in the Middle East. The sample of the study consisted of 661 young adults from Kuwait University (from divorced and intact families. The findings reveal that adults whose parents divorced show fewer positive attitudes toward marriage than do those individuals from intact marriages. The study also suggests that adults whose parents were divorced carry more positive attitudes toward divorce compared with individuals from intact marriages. Furthermore, gender was found to be an important factor in shaping attitudes toward marriage and divorce. A longitudinal study is recommended to look at the changes in young adults’ attitudes toward marriage and divorce over time, which will help to identify the influence of other factors of attitudes toward marriage and divorce.

Full Text Available This article is a synthesis of conducted researches in field of loneliness psychology, in order to reveal the feeling of loneliness and its manifestation at young adults. At this age, the main hazard represent the excessive self-concern or avoidance of interpersonal relationships. The inability to establish personal relationships of trust leads to loneliness. The causes and factors findings that could trigger loneliness, as well as their effects on young adults reflect a multi-featured phenomenon of this complex and ambiguous condition. The clear depiction deficiency of loneliness approach among young adults shows that this phenomenon may have different distinctions. As a prerequisite for personal development, as well as a multitude of causes, these can be expressed through various contexts of social isolation disclosure (voluntary or forced and life consequences of young individual. All of the above represent an additional need of developing the loneliness concept of young, based on an integrated approach and oriented towards structuring the control of loneliness and empirical data-bases.

Ergogenic risks elevate health risks in young athletes.

Giesemer, Bernard A

2003-11-01

Young athletes may use many products and techniques in an attempt to increase competitive edge in sports. The doping techniques that were previously seen in elite adult athletes are now being noted in increasingly competitive elementary, middle, and high school male and female athletes. The risk of significant morbidity and mortality associated with the use of these products is substantially increased when other risk factors are present. The risk for heat-related illness and possible heat-related mortality is higher in physiologically immature, overweight, and poorly conditioned young athletes. These are the same athletes who may be more likely to use stimulant or anabolic steroid products in attempts to catch up on training and conditioning regimens, improve their competitive advantage, or improve their physiques. The risk for heat-related incidents is higher in young athletes who are predisposed to these events because of a family trait or a previous heat-related adverse event in their own medical histories. Combinations of these factors (eg, high osmotic dietary supplements, stimulants, pre-existing medical factors, adverse ambient conditions) may significantly increase a young athlete's chances of a serious, potentially fatal event. Similarly, the risk of cardiac-related sudden death in a young athlete is significantly increased by the use of stimulants such as methamphetamine. As is the case with heat-related adverse events, the risk of cardiac-related morbidity and mortality may be significantly increased when other variables are present, such as the presence of other medications and pre-existing medical factors. As athletic competition becomes increasingly intense for younger athletes, pediatricians need to be aware of the possibility that their young patients are using ergogenic aids that may increase the risk for sudden death significantly. Pediatricians should be aware of the products available to these young competitors, and of the co-factors that

Superconductive dipole magnets for big accelerators are subjected to enormous electro-magnetic force, when they are operated with high field such as 10 Tesla. They should be constructed by means of superconductive cables, which have high Young's modulus, to obtain good performance. To develop such cables we measured the Young's moduli of cables for practical use of accelerator magnets. They are monolithic and compacted strand cables. We measured also Young's moduli of monolithic copper and brass cables for comparison. The obtained data showed the Young's moduli of 35 and 15 GPa for the monolithic and compacted strand cables, respectively. (author)

Young people with autism spectrum disorder experience high levels of emotional problems, including anxiety and depression. Adapted cognitive behavioural therapy is recommended for such difficulties. However, no evidence suggests whether emotion awareness is important in treatment outcome for young people on the autism spectrum. This study aimed to investigate the potential differences in emotion awareness between (1) young people on the autism spectrum and typically developing youth and (2) young people on the autism spectrum with and without experience of cognitive behavioural therapy. Three groups (aged 11-20 years) participated: (1) typically developing young people ( n = 56); (2) young people on the autism spectrum with no experience of cognitive behavioural therapy ( n = 23); and (3) young people on the autism spectrum who had attended cognitive behavioural therapy ( n = 33). All participants completed the Emotion Awareness Questionnaire-30 item version. Young people on the autism spectrum differed significantly from typically developing young people on the emotional awareness measure. Young people on the autism spectrum who had attended cognitive behavioural therapy scored significantly lower on the Differentiating Emotions subscale, and significantly higher on the Attending to Others' Emotions subscale, compared to young people on the autism spectrum who had not attended cognitive behavioural therapy. This study highlights the importance of psycho-educational components of cognitive behavioural therapy when adapting for young people on the autism spectrum.

Characteristics and trends of self-harming behaviour in young people.

Science.gov (United States)

Cleaver, Karen

Deliberate self-harm is recognized as a serious public health issue in young people. There is evidence that young people who self-harm are more likely to repeat self-harm, and this in turn increases their risk of completed suicide. Prevalence studies have identified that the rate of self-harm among young people is on the increase, information largely based on data arising from review and analysis of hospital attendances. However, community-based studies indicate that the prevalence is much higher, with those seen in emergency departments representing the 'tip of the iceberg' (Hawton and Rodham, 2006). Young people's motives for self-harm are discussed, as are research findings which indicate that nurses can have negative attitudes towards patients who self-harm. The article considers the implications of this for young people and identifies areas for future research.

Santhya, K G; Zavier, A J Francis

2017-11-01

In India, a substantial proportion of young people are growing up in smaller families with fewer siblings than earlier generations of young people. Studies exploring the associations between declines in sibship size and young people's life experiences are limited. Drawing on data from a sub-nationally representative study conducted in 2006-08 of over 50,000 youths in India, this paper examines the associations between surviving sibship size and young women's (age 20-24) transitions to adulthood. Young women who reported no or a single surviving sibling were categorized as those with a small surviving sibship size, and those who reported two or more surviving siblings as those with a large surviving sibship size. Bivariate and multivariate regression analyses were conducted to ascertain the relationship between sibship size and outcome indicators. Analysis was also done separately for low- and high-fertility settings. Small sibship size tended to have a positive influence in many ways on young women's chances of making successful transitions to adulthood. Young women with fewer siblings were more likely than others to report secondary school completion, participation in vocational skills training programmes, experience of gender egalitarian socialization practices, adherence to gender egalitarian norms, exercise of pre-marital agency and small family size preferences. These associations were more apparent in low- than high-fertility settings.

Full Text Available The authors in the paper analyze the phenomenon of excessive presence of the mass communication media, television in the first place, and the modern computer technology in the lives of young people, as well as the issue whether this fact influences the reduction of interpersonal communication of the young. The goal of the research was to determine to which extent the newest technological achievements are present in the lives of the young in Serbia and how often they use them as media in the process of communication with their peers, and whether this kind of mediated communication consequently leads to the reduction of interpersonal communication face-to-face, which as an ultimate result can have alienation of an individual in the modern world as a widely spread phenomenon of the present.

Nutrition support programs for young adult athletes.

Clark, N

1998-12-01

After graduating from college and entering the work force, young adult athletes often struggle with the task of fueling themselves optimally for top performance and weight control. The stresses and time constraints of work, family, and social responsibilities often result in eating fast foods on the run. These young adults can benefit from nutrition education programs in the worksite, at health clubs, in the community, and via the media. Dietitians who specialize in sport nutrition have particular appeal to these athletes, who are struggling to each well, exercise well, and stay lean yet put little time or effort into their food program. This article includes two case studies of young adults and the dietary recommendations that taught them how to make wise food choices, fuel themselves well for high energy, and control their weight.

Young adulthood represents a critical time to address elevated obesity rates and the risk of early mortality, particularly among people with serious mental illness. Few studies have assessed the benefits of lifestyle interventions targeting weight loss among these young adults. This study examined the impact of the 12-month In SHAPE lifestyle intervention on weight loss and fitness among overweight and obese young adults with serious mental illness (ages 21-30) compared with participants over age 30. Data were combined from three trials of the 12-month In SHAPE program delivered through community mental health centers. In SHAPE includes weekly fitness trainer meetings, a gym membership, and nutrition education. Primary outcomes were weight loss and change in fitness at 12 months. Participants (N=194) had a schizophrenia spectrum disorder (53%) or a mood disorder (47%). The overall sample achieved significant weight loss and improved fitness; differences between young adults (N=29) and participants over age 30 (N=165) were not significant. An important finding was that 42% of young adults achieved clinically significant reductions in cardiovascular risk, defined as ≥5% weight loss or improved fitness (>50-m increase on the 6-Minute Walk Test), compared with 54% of adults over age 30 (a nonsignificant difference between age groups). Among persons enrolled in a lifestyle intervention, overweight and obese young adults experienced benefits comparable with those of adults over age 30. Young adults with serious mental illness face high risk of gaining weight, but a meaningful proportion of these individuals can achieve clinically significant cardiovascular risk reduction, thus highlighting the need to promote lifestyle intervention participation in this group.

Young people and environment, technology, nuclear energy in France

International Nuclear Information System (INIS)

Bernhardt-Crochet, L.

1995-01-01

Young people have a particular attitude on the questions about environment and energy, and also about technology. Several inquiries show that young people are more aware of environmental questions than their elders. Their anxiety is bigger against pollution than the average of French people and it seems that they are more attentive to dangers for the planet: it is the sign of a broader opening on the world. Young people are ready to adhere to a group or association for environment and have sympathy for ecologists; they have hostility against nuclear energy. Age and education level have to be specified to complicate the question. This contribution gives some elements about the opinion of young people between 15-25 years old on environment, technology and nuclear energy in France. (N.C.)

Since October 1998, Germany's Young Generation has worked in a changed political environment: As a result of the outcome of the elections to the federal parliament in 1998 and the establishment of a federal government by SPD (the Social Democratic Party) and Alliance 90/The Greens, opting out of the peaceful uses of nuclear power has become one of the guiding principles and goals. Hence, the qualified and highly motivated young employees of nuclear companies are bound to ask themselves whether there is any future for them in nuclear engineering. The Young Generation will work for the future of nuclear technology by embarking on a series of activities. Discussions with the public, transfer of know-how, and also an intensification of contacts among all companies active in the nuclear field are only some of the items of their agenda. The purpose of the activities, and the principle, of the Young Generation is this: The Young Generation is aware of its responsibility for the future, and is ready to meet the challenges. (orig.)

This paper reports on findings from qualitative research conducted in the UK that sought to explore the connections between sexual identities and self-destructive behaviours in young people. International evidence demonstrates that there are elevated rates of suicide and alcohol abuse amongst lesbian, gay, bisexual and transgender (LGBT) youth. Rarely included in this body of research are investigations into young LGBT people's views and experiences of self-destructive behaviours. Data from interviews and focus groups with young LGBT participants suggest a strong link between homophobia and self-destructive behaviours. Utilising a discourse analytic approach, we argue that homophobia works to punish at a deep individual level and requires young LGBT people to manage being positioned, because of their sexual desire or gendered ways of being, as abnormal, dirty and disgusting. At the centre of the complex and multiple ways in which young LGBT people negotiate homophobia are 'modalities of shame-avoidance' such as: the routinization and minimizing of homophobia; maintaining individual 'adult' responsibility; and constructing 'proud' identities. The paper argues that these strategies of shame-avoidance suggest young LGBT people manage homophobia individually, without expectation of support and, as such, may make them vulnerable to self-destructive behaviours.

Comorbid physical health conditions, commonly associated with mental illness, contribute to increased morbidity and reduced life expectancy. The trajectory to poorer health begins with the onset of mental illness. For young people with mental illness, health risk behaviours and poor physical health can progress to adulthood with long-term detrimental impacts. Using a cross-sectional survey design, self-reported health risk behaviours were gathered from 56 young (16-25 years) Australians who had been hospitalised for mental illness and taking psychotropic medication. Smoking, alcohol use, minimal physical activity, and lack of primary health care were evident. While these behaviours are typical of many young people, those with mental illness have substantially increased vulnerability to poor health and reduced life expectancy. Priority needs to be given to targeted health promotion strategies for young people with mental illness to modify their risky long-term health behaviours and improve morbidity and mortality outcomes. Nurses in mental health settings play a vital role in promoting young peoples' well-being and preventing poorer physical health outcomes. Implementation of a cardiometabolic health nurse role in inpatient settings for young people with mental illness could facilitate prevention and early intervention for health risk behaviours.

Introduction: Young Fatherhood: Lived experiences and policy challenges.

The entry of young people into early parenthood has long been regarded as an issue for social policy and for professional practice in the UK and internationally. Despite a steadily falling trend, most notably since 1998, the UK still has one of the highest rates of teenage pregnancy in Europe, concentrated in the most socially disadvantaged areas of the country (Office for National Statistics, 2015). The majority of these pregnancies are unplanned, with about half resulting in the birth of a child, although the extent to which this should be a cause for concern is a contested issue (Duncan et al. , 2010). Considerable research evidence exists on the experiences of young mothers, with a range of interventions designed to meet their needs. However, young fathers (defined as those under the age of 25, a quarter of whom are estimated to be in their teens) have, until recently, been neglected in both research and policy. Over the past decade, small pockets of research evidence on the circumstances, practices and values of young fathers have begun to coalesce into a fledgling evidence base. However, the notion of 'feckless' young men, who are assumed to be absent, or disinterested in 'being there', or, worse, regarded as a potential risk to their children, continues to hold sway, particularly in popular media and some political discourses (Neale and Davies, 2015).

Although online focus groups are emerging as a worthwhile methodological approach for qualitative researchers, reporting has been constrained in several ways. The majority of studies report asynchronous groups, whereas others employ synchronous exchanges, the efficacy of which with young people has seldom been explored. Considering the popularity of the Internet as a communication tool for young people, this missed opportunity is surprising. Based on a series of synchronous online focus groups with young people, the authors explore why this approach might be an effective way of engaging young people with appearance-related concerns in research. In this article, they discuss the process of hosting and moderating synchronous online focus groups, highlighting some of the ethical, pragmatic, and personal challenges that might face researchers using this method. Through a reflexive approach, they intend to inform and encourage qualitative researchers to consider alternative ways of engaging young people in research.

Strokes In Young Adults And Children

Full Text Available Stroke is in second place on a mortality list in the world. Also, stroke is a leading cause of disability. Approximately 20% of all strokes occur in Children and young adults. The etiology of stroke in Children and young adults is different from that in older patients, and has an influence on diagnostic evaluation and treatment, so knowledge about older patients cannot always be applied to these patients. The list of stroke etiologies among young adults and children is extensive. Ischemic stroke are more frequent than hemorrhagic strokes in both groups. Stroke in young adults had been thought to be associated with   risk factors, including arterial (such as dissection, reversible cerebral vasoconstriction syndrome, inflammatory arteritis ,moyamoya ,migraine - induced stroke, genetic or inherted arteriopathy, premature atherosclerosis cardiac (such as patent foramen ovale, cardiomyopathy , congenital heart disease and   hematologic (such as  deficiencies of protein S,protein C,or antithrombin;factor V lieden mutation . Common risk factors for stroke in children include: Sickle-cell disease, diseases of the arteries, abnormal blood clotting, head or neck trauma. There are no specific recommendations or guidelines for primary or secondary stroke prevention in young adults. Primary prevention focused on identifying and managing known vascular risk factors, such as hypertension, disorders of lipid metabolism, and diabetes, and non-drug strategies and lifestyle changes, including smoking, reducing body weight, increasing regular aerobic physical activity, and adopting a healthy diet with more fruit and vegetables and less salt. For secondary stroke prevention, identification of the etiologic mechanism of the initial stroke and the presence of any additional risk factors is most important. It consists of optimal treatment of vascular risk factors administering antiplatelet or anticoagulant therapy, and if indicated, invasive surgical or

Previous research has shown a relationship between childhood/adolescent chronic conditions and negative health behaviors, psychological outcomes, and social outcomes. Less is known about whether these negative outcomes are experienced by young adults with chronic health conditions. The purpose of this paper is to investigate how young adults' BMI, health behaviors, and psychological and social outcomes differ depending on whether they have diabetes, asthma, or neither of these chronic conditions. Data were drawn from the third wave of Project EAT-III: Eating and Activity in Young Adults, a population-based study of 2287 young adults (mean age = 25.3; range 19.8 - 31.2). General linear models were used to test differences in BMI, health behaviors (e.g., fast food intake) and psychosocial outcomes (e.g. depressive symptoms) by young adults' chronic disease status. Young adults with diabetes had higher BMIs, engaged in less physical activity and more unhealthy weight control behaviors and binge eating, had lower self-esteem and lower body satisfaction, and experienced more depressive symptoms and appearance-based teasing compared to young adults with asthma or no chronic conditions, after adjusting for age, race/ethnicity, socio-economic status (SES) and, when relevant, for BMI. There were no significant differences between young adults with asthma and young adults with no chronic condition on all of the psychosocial and health behavior outcomes. Young adults with diabetes reported higher prevalence of negative health behaviors and psychosocial outcomes. Providers may find it useful to assess for negative health behaviors and psychosocial variables with young adults with diabetes in order to improve treatment and quality of life for these individuals.
