Genetic parameter estimates for carcass and yearling ultrasound measurements in Brangus cattle.

Carcass measurements of 12th-rib fat thickness (CARCFAT), longissimus muscle area (CARCLMA), and weight (CARCWT) on 2,028 Brangus and Brangus-sired fed steers and heifers, as well as yearling weights (YWT) and ultrasound measures of 12th-rib fat thickness (USFAT) and longissimus muscle area (USLMA) on 3,583 Brangus bulls and heifers were analyzed to estimate genetic parameters. Data were analyzed using a six-trait animal model and an average information REML algorithm. The model included fixed effects for contemporary group and breed of dam, covariates for age at slaughter or measurement, and random animal and residual effects. Heritabilities for CARCFAT, CARCLMA, CARCWT, USFAT, USLMA, and YWT were . 27+/-. 05, . 39+/-. 05, . 59+/-. 06, . 11+/-. 03, . 29+/-. 04, and . 40+/-. 04, respectively. Genetic correlations between CARCFAT and USFAT, CARCLMA and USLMA, and CARCWT and YWT were . 69+/-. 18, . 66+/-. 14, and . 61+/-. 11, respectively. The favorable and moderately strong genetic correlations between carcass measurements and similar yearling breeding-animal ultrasound measurements indicate that such measurements of 12th-rib fat and longissimus muscle area are useful in predicting genetic values for carcass leanness and longissimus muscle area. Selection using yearling ultrasound measurements of breeding cattle should result in predictable genetic improvement for carcass characteristics. Inclusion of yearling ultrasound measurements for fat thickness and longissimus muscle area should enhance national cattle evaluation programs.
The Association of Pre-S/S Gene Mutations and Hepatitis B Virus Vertical Transmission

Background HBV Pre-S/S gene mutations can occur before or after implementation of combined vaccination program. HBV Prs-S/S gene mutation is a risk factor of vaccination failure and frequently causes HBV vertical transfection. Objectives To assess the association of hepatitis B virus (HBV) S gene mutations with vertical transmission. Patients and Methods In this prospective nested case-control study, a total of 60 pregnant women with positive serum HBsAg and HBV DNA ≥ 107 IU/mL were divided into a case group (15 cases with vaccination failure) and a control group (45 cases with vaccination success) according to whether their infants tested positive for HBV infection. Mothers and their children in the case group were further sub-divided into groups including mothers, newborns and infant (the same newborns at age of seven months). The pre-S/S gene mutations were detected by PCR and sequenced and its association with vertical transmission of HBV was analyzed. Results HBV genotype B was the dominant genotype in the both groups’ mothers. Each mother-child pair in case group had the same HBV genotype. There were no significant differences in mutation frequencies of HBV Pre-S/S gene between case and control groups’ mothers (Fragment 1 (M): 2 vs. 4, P > 0.05; Fragment 2 (M): 10 vs. 10, P > 0.05), or among the mothers, newborns and infants in the case group (Fragment 1 (M): 2, 2, and 3, respectively, P > 0.05; Fragment 2 (M): 10, 10 and 10 respectively, P > 0.05). Mutation site analysis of the both groups’ mothers demonstrated 108 different mutation sites in the HBV pre-S/S gene, with 105 silent mutations and 5 missense mutations including ntA826G, ntC531T, ntT667C, ntC512T and ntC546A. Among 15 mother-newborn-infant pairs with successful PCR and sequence in case group, 7 (41.17%) mother-newborn pairs, 9 (60.00%) mother-infant pairs and 3 (20.00%) infant-newborn pairs had different mutation sites. Conclusions HBV in children due to vaccination failure was resulted from vertical transmission. HBV Pre-S/S gene mutations were prevalent and could occur before or after vaccination. Therefore, simply analyzing mutation frequency of HBV gene was not of value. To advance blocking HBV vertical transmission, future studies should focus on specific mutation sites, potentially associated with vaccination failure.
Importance of Coronoidotomy and Masticatory Muscle Myotomy in Surgical Release of Trismus Caused by Submucous Fibrosis

Thirty patients with trismus resulting from betel nut chewing–induced oral submucous fibrosis were treated with either fibrotic tissue release only (group I) or fibrotic tissue release in combination with masticatory muscle myotomy and coronoidotomy (group II). The latter procedures were only performed in patients whose intraoperative interincisal distance remained less than 35 mm immediately after submucous fibrous tissue release. There were eight and 22 patients in groups I and II, respectively. In group I patients, the average intraoperative interincisal distance improved from 19.5 mm to 42 mm. In group II patients, the average intraoperative interincisal distance improved from 13.5 mm to 27 mm after fibrotic tissue release and further improved to 40 mm after masticatory muscle myotomy and coronoidotomy. At an average follow-up of 22.1 months (range, 7 to 70 months), the group I and II patients had an average interincisal distance of 41.5 mm (range, 35 to 50 mm) and 32.9 mm (range, 20 to 42 mm), respectively. These results demonstrate the efficacy of submucous fibrotic tissue release in treating trismus resulting from betel nut chewing–induced submucous fibrosis and confirm the role of additional masticatory muscle and coronoidotomy in treating its severe forms.
Relationship of smoking and coffee and alcohol consumption with seroconversion to Helicobacter pylori: A longitudinal study in hospital workers

Background and Aim: There are few data concerning the relationship between Helicobacter pylori seroconversion, and smoking habits and coffee and alcohol consumption. The aim of the present study was to investigate the relationship between smoking habits, coffee and alcohol consumption, and H. pylori seroconversion.
From the Surface to the Deep-Sea: Bacterial Distributions across Polymetallic Nodule Fields in the Clarion-Clipperton Zone of the Pacific Ocean

Marine bacteria regulate fluxes of matter and energy essential for pelagic and benthic organisms and may also be involved in the formation and maintenance of commercially valuable abyssal polymetallic nodules. Future mining of these nodule fields is predicted to have substantial effects on biodiversity and physicochemical conditions in mined areas. Yet, the identity and distributions of bacterial populations in deep-sea sediments and associated polymetallic nodules has received relatively little attention. We examined bacterial communities using high-throughput sequencing of bacterial 16S rRNA gene fragments from samples collected in the water column, sediment, and polymetallic nodules in the Pacific Ocean (bottom depth ≥4,000 m) in the eastern Clarion-Clipperton Zone. Operational taxonomic units (OTUs; defined at 99% 16S rRNA gene identity) affiliated with JTB255 (Gammaproteobacteria) and Rhodospirillaceae (Alphaproteobacteria) had higher relative abundances in the nodule and sediment habitats compared to the water column. Rhodobiaceae family and Vibrio OTUs had higher relative abundance in nodule samples, but were less abundant in sediment and water column samples. Bacterial communities in sediments and associated with nodules were generally similar; however, 5,861 and 6,827 OTUs found in the water column were retrieved from sediment and nodule habitats, respectively. Cyanobacterial OTUs clustering among Prochlorococcus and Synechococcus were detected in both sediments and nodules, with greater representation among nodule samples. Such results suggest that vertical export of typically abundant photic-zone microbes may be an important process in delivery of water column microorganisms to abyssal habitats, potentially influencing the structure and function of communities in polymetallic nodule fields.
A soluble dominant negative fibroblast growth factor receptor 4 isoform in human MCF-7 breast cancer cells.

Fibroblast growth factor receptors (FGFRs) are receptor tyrosine kinases encoded by four closely related genes. FGFR 1, 2, and 3 have a number of isoforms derived by alternative splicing, alternative initiation and exon switching; however, FGFR4 has been reported to encode a single intact receptor with three extracellular immunoglobulin (Ig)-like domains, a transmembrane domain, and a split intracellular kinase. Here we describe a novel C-terminally truncated soluble isoform of FGFR4 expressed by human epithelial breast cancer MCF-7 cells. This isoform results from failure of splicing of intron 4 resulting in an mRNA species that encodes an in-frame premature stop codon. Cells transfected with the corresponding cDNA containing intron 4 express a truncated releasable protein that is identified in conditioned media. This soluble FGFR4 isoform (sFGFR4) abrogates the effect of FGF-1-induced MAPK phosphorylation and PRL gene activation. These findings represent the first description of an endogenous soluble C-terminally truncated FGFR4 isoform with FGF modulatory properties.

The Energy Cost of Human Locomotion on Land and in Water*

The energy cost of the forms of locomotion discussed throughout this article is summarized in Table 9. This table, as well as the preceding sections of this article, are designed to provide a rather comprehensive and simple set of information for potential readers: medical doctors, who should be able to prescribe to their patients (obese, hypertensive, cardiac, etc.) the correct amount and type of exercise, thus making use of exercise as of any other drug, of which it is imperative to know posology and contraindications; athletes, trainers, and sportsmen in general, who should gear correctly their diet to the type and amount of physical exercise; physical educators, who should be aware of the specific characteristics of the exercise modes they propose to their pupils, as a function of their sex, age, and athletic capacity. However, besides these practical applications, the notions discussed throughout this article bear also a more general interest. Indeed, they allow a better understanding of the motion of man, that is, of the only machine, which besides moving about, also tries to understand how he does it.
Biogenic Silver for Disinfection of Water Contaminated with Viruses

ABSTRACT The presence of enteric viruses in drinking water is a potential health risk. Growing interest has arisen in nanometals for water disinfection, in particular the use of silver-based nanotechnology. In this study, Lactobacillus fermentum served as a reducing agent and bacterial carrier matrix for zerovalent silver nanoparticles, referred to as biogenic Ag0. The antiviral action of biogenic Ag0 was examined in water spiked with an Enterobacter aerogenes-infecting bacteriophage (UZ1). Addition of 5.4 mg liter−1 biogenic Ag0 caused a 4.0-log decrease of the phage after 1 h, whereas the use of chemically produced silver nanoparticles (nAg0) showed no inactivation within the same time frame. A control experiment with 5.4 mg liter−1 ionic Ag+ resulted in a similar inactivation after 5 h only. The antiviral properties of biogenic Ag0 were also demonstrated on the murine norovirus 1 (MNV-1), a model organism for human noroviruses. Biogenic Ag0 was applied to an electropositive cartridge filter (NanoCeram) to evaluate its capacity for continuous disinfection. Addition of 31.25 mg biogenic Ag0 m−2 on the filter (135 mg biogenic Ag0 kg−1 filter medium) caused a 3.8-log decline of the virus. In contrast, only a 1.5-log decrease could be obtained with the original filter. This is the first report to demonstrate the antiviral efficacy of extracellular biogenic Ag0 and its promising opportunities for continuous water disinfection.
The AAA ATPase VPS4/SKD1 Regulates Endosomal Cholesterol Trafficking Independently of ESCRT‐III

The exit of low‐density lipoprotein derived cholesterol (LDL‐C) from late endosomes (LE)/lysosomes (Ly) is mediated by Niemann–Pick C1 (NPC1), a multipass integral membrane protein on the limiting membranes of LE/Ly, and by NPC2, a cholesterol‐binding protein in the lumen of LE/Ly. NPC2 delivers cholesterol to the N‐terminal domain of NPC1, which is believed to insert cholesterol into the limiting membrane for subsequent transport to other subcellular organelles. Few cytoplasmic factors have been identified to govern cholesterol efflux from LE/Ly, and much less is known about the underlying molecular mechanisms. Here we establish VPS4, an AAA ATPase that has a well‐established role in disassembling the ESCRT (endosomal sorting complex required for transport)‐III polymer, as an important regulator of endosomal cholesterol transport. Knocking down VPS4 in HeLa cells resulted in prominent accumulation of LDL‐C in LE/Ly, and disrupted cholesterol homeostatic responses at the endoplasmic reticulum. The level and localization of NPC1 and NPC2 appeared to be normal in VPS4 knockdown cells. Importantly, depleting any of the ESCRT‐III components did not exert a significant effect on endosomal cholesterol transport. Our results thus identify an important cytoplasmic regulator of endosomal cholesterol trafficking and represent the first functional separation of VPS4 from ESCRT‐III.
A Policy of Individualization and Flexibility Ignoring the Situation of Non-Self-Reliant Individuals: The Example of Swedish Basic Adult Education.

Based on a case study in Swedish municipal basic adult education this article addresses current policies for providing individualized and flexible learning, which have been reinforced in recent adult education reforms. Concepts from the organization theory of “action nets” have been used. Institutionalized procedures and a number of “organizing knots” have been identified. The results display a paradox in relation to the policy imperatives of individualization and flexibility: successful individualized and flexible studies show to be quite strictly conditioned. We provide different aspects of how students connect strongly to this rigorous learning design and perform well, but also confirm results of previous studies which show how such study forms require an “individual self-reliant learner”. However, not all students act and participate in accordance with the institutionalized procedures. We identify a significant lack of organizing knots for a group of young students, who had recently arrived in Sweden without any of their family members and who encounter difficulties in pursuing their studies and need educational support. We discuss how this is related to the Education Act (SFS 2010:800, Ch. 2, §26) that states that professional and psychological support, health care and special needs is optional in municipal adult education, and argue that the current policy of Swedish adult education with the reinforced “individualized perspective” actually ignores the context and life situations of many individuals.
Regional differences in entrepreneurial perceptions and implications for the Romanian competitiveness policy

Abstract Understanding entrepreneurship as being spatially rooted transforms it in a regional and national competitiveness factor. Despite the increasing importance of the territorial dimension in supporting economic growth at policy and declarative levels, in practice, in Romania, the territorial structure and spatial organization of the economy contributes little to the national value added. In this context, we study regional differences in entrepreneurial initiative and perception and their possible impact on the national competitiveness strategy. We use primary data collected in three Romanian regions (Centre, North-East, Bucureşti-Ilfov) and conduct a statistical analysis of the data. The results indicate different comparative regional profiles. The regional differences in the intentions, motivations, barriers and limitation for entrepreneurship confirm the theoretical view that personal motivations of becoming an entrepreneur are determined by environmental conditions. We conclude that the regional differences should be taken into account in the elaboration of the competitiveness policy, corroborated with the results of other similar studies.
Endovascular management of intracranial vertebral artery dissecting aneurysms.

OBJECT Intracranial vertebral artery (VA) dissecting aneurysms often present with severe subarachnoid hemorrhage (SAH) and dramatic neurological injury. The authors reviewed the management of 23 cases in an effort to evaluate treatment efficacy and outcomes. METHODS The records of 23 patients who underwent endovascular treatment were reviewed to determine symptoms, type of therapy, complications, and clinical outcomes. All patients were evaluated using records kept in a prospectively maintained database. Ten men and 13 women (age range 35-72 years; mean age 49 years) were treated over an 8-year period. Twelve patients presented with poor-grade SAH, five with good-grade SAH, three with headache, and two with stroke. The other patient's aneurysm was discovered incidentally. Treatment included coil occlusion of the artery at the aneurysm in 21 patients and stent-assisted coil placement in two. Parent artery sacrifice was successful in all cases, whereas both patients treated with stent-assisted coil insertion suffered recurrences. No patient sustained permanent complications as a result of treatment. Two patients died due to the severity of their original SAH. Findings were normal in 14 patients on follow-up review (including five of the 12 presenting with poor-grade SAH), five had fixed neurological deficits but were able to care for themselves, and one was permanently disabled. CONCLUSIONS Despite their often aggressive neurological presentation, intracranial VA dissecting aneurysms can be managed safely with coil occlusion of the lesion and/or parent artery. Even patients presenting in poor neurological condition may improve dramatically.
Cutting Edge: CD69 Interference with Sphingosine-1-Phosphate Receptor Function Regulates Peripheral T Cell Retention

Tissue-resident memory T cells provide local immune protection in barrier tissues, such as skin and mucosa. However, the molecular mechanisms controlling effector T cell retention and subsequent memory formation in those locations are not fully understood. In this study, we analyzed the role of CD69, an early leukocyte activation marker, in regulating effector T cell egress from peripheral tissues. We provide evidence that CD69 surface expression by skin-infiltrating CD8 T cells can be regulated at multiple levels, including local Ag stimulation and signaling through type I IFNRs, and it coincides with the transcriptional downregulation of the sphingosine-1-phosphate receptor S1P1. Importantly, we demonstrate that expression of CD69, by interfering with sphingosine-1-phosphate receptor function, is a critical determinant of prolonged T cell retention and local memory formation. Our results define an important step in the generation of long-lived adaptive immune memory at body surfaces.
Ten-year Investigation of Clinical, Laboratory and Radiologic Manifestations and Complications in Patients with Takayasu's Arteritis in Three University Hospitals.

BACKGROUND Takayasu arteritis is a condition of unknown aetiology that affects the aorta and its primary branches. The disease has been primarily recognized and described in Asia. The aims of this study were to identify the main clinical, laboratory, and angiographic features of Takayasu arteritis in Iranian patients over a 10 year period from 2000 to 2010. METHODS Data were obtained from angiographic and medical records of patients treated at Shahid-Rajai, Taleghani, and Loghman Hospitals during the above-mentioned time period. The criteria for definitions and findings were those proposed by the American College of Rheumatology. RESULTS A total of 15 patients were identified. The median age at presentation was 36 years and 73.3% of patients were females. Fever was the most common presentation. According to "modified" National Institute of Health criteria, 44.7% of patients were in the acute phase of disease with systemic symptoms such as fever, weight loss, and elevated C-reactive protein (CRP) levels. Immunological markers such as antinuclear antibodies (ANA) and antineutrophil cytoplasmic antibodies (C-ANCA) were absent. The tuberculin test result was positive in 40% of the patients. Vascular bruit was present in 86.7% and hypertension was detected in 53.3% with 13.3% having associated renal artery stenosis. The angiographic manifestations were classified as; type I, cervicobrachial type (26.6%); type II, thoracoabdominal type (20.0%); type III, peripheral type (6.6%); and type IV, generalised type (46.7%). Coronary arteries were involved in three cases, pulmonary in two and renal in two. CONCLUSION Based on our findings, the most common clinical, laboratory and angiographic findings were fever, increased erythrocyte sedimentation rate (ESR) and stenosis, respectively. Because of dangerous consequences of this disease, attention to fever and increased ESR, especially in young women may be helpful for physicians to prevent diagnosis delay.
Predictive Factors for the Development of Type II Endoleaks

Purpose To define predictive factors for endoleak type II (EL-II) based on quantifiable factors in the imaging studies of patients undergoing endovascular aneurysm repair (EVAR). Methods The data on 208 consecutive patients (137 men; mean age 75.2 years, range 62–84) who underwent EVAR between the years 2003 and 2008 were retrospectively reviewed. The abdominal aortic aneurysm (AAA) diameter ranged from 4.8 to 12.8 cm. Data were collected on the type of AAA; the type of stent-graft (aortomonoiliac versus bifurcated); the performance of hypogastric artery embolization; the presence, number, diameter, and patency of aortoiliac branches identified on the pre and post-EVAR imaging studies; and the presence and type of EL-II (transient vs. persistent) with the goal of identifying any imaging-based predictive factors for the development of EL-II. Results Among the 208 cases, 11 patients had endoleaks other than type II and were excluded, leaving 195 patients for analysis. In all, 28 (13.4%) patients were diagnosed with EL-II. All had ≥4 patent lumbar arteries (mean diameter >2.3 mm). Ten patients with a transient EL-II had a mean of 4.3 patent lumbar arteries, which had diameters <2 mm (mean 1.5 mm). In the 18 patients with persistent EL-II, the mean diameter of the 4 lumbar arteries was 2.7 mm; at least 1 of the lumbar arteries was >2 mm. The presence of at least 4 patent lumbar arteries (p<0.001) and at least 1 patent hypogastric artery (p<0.001) were predictive factors for EL-II. At least 1 lumbar artery >2 mm in diameter was a positive predictive factor for the development of persistent EL-II (p<0.001). Conclusion Patent hypogastric and lumbar arteries are significantly associated with a higher risk of developing EL-II. Larger diameter lumbar arteries tend to be associated with persistent EL-IIs, while lumbar arteries <2 mm would more likely be seen with a transient EL-II. If substantiated in larger studies, these angiographic criteria may guide early treatment of EL-II to avoid aneurysm sac expansion and potential rupture.
