Pax-3 expression in segmental mesoderm marks early stages in myogenic cell specification.

Specification of the myogenic lineage begins prior to gastrulation and culminates in the emergence of determined myogenic precursor cells from the somites. The myoD family (MDF) of transcriptional activators controls late step(s) in myogenic specification that are closely followed by terminal muscle differentiation. Genes expressed in myogenic specification at stages earlier than MDFs are unknown. The Pax-3 gene is expressed in all the cells of the caudal segmental plate, the early mesoderm compartment that contains the precursors of skeletal muscle. As somites form from the segmental plate and mature, Pax-3 expression is progressively modulated. Beginning at the time of segmentation, Pax-3 becomes repressed in the ventral half of the somite, leaving Pax-3 expression only in the dermomyotome. Subsequently, differential modulation of Pax-3 expression levels delineates the medial and lateral halves of the dermomyotome, which contain precursors of axial (back) muscle and limb muscle, respectively. Pax-3 expression is then repressed as dermomyotome-derived cells activate MDFs. Quail-chick chimera and ablation experiments confirmed that the migratory precursors of limb muscle continue to express Pax-3 during migration. Since limb muscle precursors do not activate MDFs until 2 days after they leave the somite, Pax-3 represents the first molecular marker for this migratory cell population. A null mutation of the mouse Pax-3 gene, Splotch, produces major disruptions in early limb muscle development (Franz, T., Kothary, R., Surani, M. A. H., Halata, Z. and Grim, M. (1993) Anat. Embryol. 187, 153-160; Goulding, M. , Lumsden, A. and Paquette, A. (1994) Development 120, 957-971). We conclude, therefore, that Pax-3 gene expression in the paraxial mesoderm marks earlier stages in myogenic specification than MDFs and plays a crucial role in the specification and/or migration of limb myogenic precursors.
Bilateral pelvi-ureteric junction obstruction: our experience in a developing country.

BACKGROUND Bilateral pelvi-ureteric junction (PUJ) obstruction is rare and causes high morbidity and mortality. Recent advances have led to its diagnosis and management in the perinatal period. However, open surgery is still the mainstay of treatment in less endowed nations where late presentation is the norm. MATERIALS AND METHODS All patients with PUJ obstruction diagnosed and managed at the University of Maiduguri Teaching Hospital between January 2006 and December 2011 were retrospectively reviewed. All had open surgery and all repairs were stented with double J stents or appropriate size feeding tube. RESULTS A total of 18 patients were analyzed, 11 males and 7 females with a ratio of 1.57:1 and mean age of 27.5 years (age range 2-38). The main clinical features were loin pain (72.22%) and fever (72.22%); while the main complications at presentation were hydronephrosis (55.56%), impaired renal function (61.11%) and pyelonephritis (50%). The causes of obstruction were mainly congenital (50.0%) and due to schistosomal fibrosis/stricture (22.2%). Preliminary double J stents, tube nephrostomies and hemodialysis were used to recover renal function before surgery. Anderson-Hynes (41.7%) and Heineke-Mirhulicz (19.4%) pyeloplasty were the main procedures performed. The main post-operative complications were urinary tract infections (67.67%) and leakage (11.11%). The mean duration of symptoms was 23.72 months and the mean hospital stay was 13 days. The mortality rate was 5.56%. CONCLUSION Bilateral PUJ obstruction is uncommon in Maiduguri, with congenital causes and schistosomal fibrosis as the most common etiologies. Aggressive treatment aimed at recovering renal function is necessary before open pyeloplasty if morbidity and mortality is to be reduced. Open pyeloplasty remained the best treatment option with favorable outcome.
Near-infrared Spectroscopy in the Brewing Industry

This article offers an exhaustive description of the use of Near-Infrared (NIR) Spectroscopy in the brewing industry. This technique is widely used for quality control testing of raw materials, intermediates, and finished products, as well as process monitoring during malting and brewing. In particular, most of the reviewed works focus on the assessment of barley properties, aimed at quickly selecting the best barley varieties in order to produce a high-quality malt leading to high-quality beer. Various works concerning the use of NIR in the evaluation of raw materials, such as barley, malt, hop, and yeast, are also summarized here. The implementation of NIR sensors for the control of malting and brewing processes is also highlighted, as well as the use of NIR for quality assessment of the final product.
Food hygiene training in small to medium-sized care settings

Adoption of safe food handling practices is essential to effectively manage food safety. This study explores the impact of basic or foundation level food hygiene training on the attitudes and intentions of food handlers in care settings, using questionnaires based on the Theory of Planned Behaviour. Interviews were also conducted with food handlers and their managers to ascertain beliefs about the efficacy of, perceived barriers to, and relevance of food hygiene training. Most food handlers had undertaken formal food hygiene training; however, many who had not yet received training were preparing food, including high risk foods. Appropriate pre-training support and on-going supervision appeared to be lacking, thus limiting the effectiveness of training. Findings showed Subjective Norm to be the most significant influence on food handlers' intention to perform safe food handling practices, irrespective of training status, emphasising the role of important others in determining desirable behaviours.
Differential Effects of Aging on the Functions of the Corpus Callosum

Several structural imaging studies have revealed atrophy in regions of the corpus callosum due to normal aging. We examined the performance of young and senior adults on 2 behavioral measures of interhemispheric interactions to test for possible functional consequences of callosal decline. In a simple reaction time task, the efficiency of sensorimotor transfer was assessed by comparing response times from conditions that required interhemispheric transfer (e.g., the left hand responding to a right visual field light) to those from conditions that did not require transfer (e.g., the left hand responding to a left visual field light). Older adults were selectively slower when interhemispheric transfer was required. In the second task, participants matched letters presented within the same visual field or in opposite visual fields. This task is thought to index attentional functions of the corpus callosum, in particular, callosal contributions to resource allocation (Banich, 1998). For more difficult tasks, older participants showed a performance advantage on bilateral conditions requiring transfer compared to unilateral conditions that did not require transfer. This advantage equaled or exceeded that observed in younger adults. Together these results suggest that age does not have uniform effects on callosal function. Whereas sensorimotor functions show age-related decline, attentional functions of the corpus callosum may be relatively preserved and assume a more prominent role in the aging brain.
Studies on Genetic Variability , Heritability and Genetic Advance in Segregating Generations of Faba Bean ( Vicia Faba L . )

The present search was conducted at the Experimental Farm of Faculty of Agriculture, Al-Azhar University, Assiut branch during three successive winter seasons of 2011/2012, 2012/2013 and 2013/2014. Pedigree selection was used in three segregating generations (F2, F3 and F4 generations) of faba bean of two crosses (Looza X Giza 40 and Looza X Assiut 67). The tested characters were number of shoots/plant, number of pods/plant, number of seed/pod, seed yield/plant and 100-seed weight. The objective of this study was to estimate phenotypic (PCV) and genotypic (GCV) coefficients of variability, heritability in broad sense, expected gain from selection (GA) and realized gain from selection (RG). Results indicated that PCV and GCV estimates decreased from segregating generation to another. The results of broad sense heritability demonstrated that heritability values of all studied characters were reduced from filial to filial according to pedigree selection which increases of homogeneity of plants. Heritability estimates for seed yield/plant and 100-seed weight in F4 were 82.10 and 83.53 in population1 and were 65.81 and 81.01 in population 2, respectively. GA and RG estimates were useful and decreased in sequence generations in all studied traits. GA estimates in F3 were (25.89, 22.71) and (27.91, 22.16) for seed yield /plant and 100-seed weight in cross1 and cross2, respectively, and RG estimates for seed yield /plant and 100-seed weight in F4 were (22.14, 1.89) and (4.60, 9.25) for cross1 and cross2, respectively. The results indicated that the genetic advance estimates were observed in two crosses. The investigator gets many good families; it can be become good lines after complete selection processes.
Relationship between physical activity and type of smoking behavior among adolescents and young adults in Cyprus.

INTRODUCTION Research suggests that physical activity protects against youth smoking. As a result, prevention programs that focus on physical activity to address the problem of smoking hold promise. However, more research is needed to examine the relationship between physical activity and smoking and how physical activity might be used in smoking prevention and intervention programs. The present study examined the relationship between physical activity and smoking among adolescents and young adults using a sample from Cyprus. We investigated the association between level of physical activity (very active, active, moderately active, or inactive) and type of smoking behavior (nonsmoker; occasional, regular light, or regular heavy smoker). METHODS Participants were 1,390 Cypriot adolescents and young adults who completed a packet of questionnaires related to smoking and physical activity. Physical activity and demographic factors were analyzed in terms of their effect on smoking behavior. RESULTS A consistent and negative relationship between physical activity and smoking emerged across both sex and age. The greater the intensity of youths' physical activity, the less likely they were to smoke. Compared with inactive individuals, physically active individuals smoked fewer cigarettes and were more likely to be nonsmokers or occasional smokers. Among physically active individuals, those engaging in more intense activity were less likely to be heavy or light smokers. DISCUSSION Results of the present study indicate that physical activity may be used as a preventive measure against smoking in adolescents and young adults.
Ideophones and Reduplication: Depiction, Description, and the Interpretation of Repeated Talk in Discourse

Repetition is one of the most basic operations on talk, often discussed for its iconic meanings. Ideophones are marked words that depict sensory imagery, often identified by their reduplicated forms. Yet not all reduplication is iconic, and not all ideophones are reduplicated. This paper discusses the semantics and pragmatics of repeated talk with special reference to ideophones. To understand these phenomena, it is useful to distinguish two modes of representation in language — description and depiction — along with cues like prosodic foregrounding that help steer listener’s interpretations from one to the other. Reduplication can partake in both modes, which is why it is common in ideophones and other areas of grammar. Using evidence from a range of languages, this paper shows how the study of ideophones sheds light on the interpretation of repeated talk, and argues that both description and depiction are fundamental to understanding how language works.
Interferon-alpha 2b, with or without prior hepatic artery embolization: clinical response and survival in mid-gut carcinoid patients. The Norwegian carcinoid study.

BACKGROUND Mid-gut carcinoid tumours often present with liver metastases, and survival has then been less than 2 years in earlier reports. We have evaluated the effects of interferon therapy on clinical response and survival, with or without hepatic artery embolization in these patients. METHODS In a prospective study 30 female and 12 male patients, aged 23 to 75 years, with mid-gut carcinoid tumours and liver metastases underwent surgery with removal of as much as possible of their primary tumour. If technically feasible, embolization of hepatic arteries was performed in the absence of contraindications. Seventeen patients were embolized, and all patients received interferon-alpha 2b treatment for 1 year. Response factors were computer tomography (CT) measurement of the largest liver metastasis and the 24-h urinary excretion of 5-hydroxyindoleacetic acid (5-HIAA). After 12 months patients with objective response or stable disease either continued or withdrew from interferon therapy. Survival was estimated when all patients had been observed for at least 36 months. RESULTS Nine patients reduced the dose, and five withdrew from interferon treatment owing to side-effects the 1st year. Three patients died. Fifteen patients (39%) showed objective response 12 months after inclusion. Cumulative 5-year survival estimated from inclusion was 37.5% in all 42 patients but 71.4% in those who continued interferon therapy. The difference in survival between the interferon-treated and those who withdrew from interferon therapy at 12 months was significant when embolization was corrected for in a Cox model (p < 0.0125). The seemingly increased survival in embolized versus non-embolized patients did not reach statistical significance (p = 0.07). CONCLUSION Interferon induced an objective response in mid-gut carcinoid patients as judged by the 24-h urinary 5-HIAA excretion. Patients receiving continuous interferon therapy showed improved response and survival compared with patients who stopped the treatment. Regardless of medical therapy, more survivors and more responders, as evaluated from CT measurements, were found among the embolized patients than among the non-embolized. Embolization could, however, not be shown to have a significant effect on survival.
Animal Models of Arthritis: Relevance to Human Disease

Animal models of arthritis are used to evaluate potential antiarthritis drugs for clinical use. Therefore capacity of the model to predict efficacy in human disease is one of the most important criteria in model selection. Animal models of rheumatoid arthritis (RA) with a proven track record of predictability include rat adjuvant arthritis, rat type II collagen arthritis, mouse type II collagen arthritis, and antigen-induced arthritis in several species. Agents currently in clinical use (or trials) that are active in these models include corticosteroids, methotrexate, nonsteroidal anti-inflammatory drugs, cyclosporin A, leflunomide, interleukin-1 receptor antagonist, and soluble tumor necrosis factor receptors. For some of these agents, the models also predict that toxicities seen at higher doses for prolonged periods would preclude dosing in humans at levels that might provide disease-modifying effects. Animal models of osteoarthritis (OA) include mouse and guinea pig spontaneous OA, meniscectomy and ligament transection in guinea pigs, meniscectomy in rabbits, and meniscectomy and cruciate transection in dogs. None of these models have a proven track record of predictability in human disease because there are no agents that have been proven to provide anything other than symptomatic relief in human OA. Efficacy data and features of the various models of RA and OA are discussed with emphasis on their proven relevence to human disease.
Invasive fungal infections: a review of epidemiology and management options.

Fungi are increasingly recognised as major pathogens in critically ill patients. Candida spp. and Cryptococcus spp. are the yeasts most frequently isolated in clinical practice. The most frequent filamentous fungi (moulds) isolated are Aspergillus spp. , but Fusarium spp. , Scedosporium spp. , Penicillium spp. , and Zygomycetes are increasingly seen. Several reasons have been proposed for the increase in invasive fungal infections, including the use of antineoplastic and immunosuppressive agents, broad-spectrum antibiotics, and prosthetic devices and grafts, and more aggressive surgery. Patients with burns, neutropenia, HIV infection and pancreatitis are also predisposed to fungal infection. The epidemiology and clinical features of fungal infections are reviewed, together with antifungal agents currently or soon to be available.
Soluble FLT1 sensitizes endothelial cells to inflammatory cytokines by antagonizing VEGF receptor-mediated signalling

AIMS Pre-eclampsia affects 5-7% of pregnancies, and is a major cause of maternal and foetal death. Elevated serum levels of placentally derived splice variants of the vascular endothelial growth factor (VEGF) receptor, soluble fms-like tyrosine kinase-1 (sFLT1), are strongly implicated in the pathogenesis but, as yet, no underlying mechanism has been described. An excessive inflammatory-like response is thought to contribute to the maternal endothelial cell dysfunction that characterizes pre-eclampsia. We hypothesized that sFLT1 antagonizes autocrine VEGF-A signalling, rendering endothelial cells more sensitive to pro-inflammatory factors also released by the placenta. We tested this by manipulating VEGF receptor signalling and treating endothelial cells with low doses of tumour necrosis factor-α (TNF-α). METHODS AND RESULTS Application of recombinant sFLT1 alone did not activate human umbilical vein endothelial cells (HUVECs). However, antagonizing the autocrine actions of endothelial VEGF-A and/or placenta growth factor (PlGF) by pre-incubation with recombinant sFLT1, anti-FLT1, anti-VEGF receptor 2 (KDR), anti-VEGF-A, VEGF receptor tyrosine kinase inhibitor SU5614, or knocking-down FLT1 or KDR transcripts rendered cells more sensitive to low doses of TNF-α. Each treatment increased activation, as measured by increases in endothelial intercellular adhesion molecule 1 (ICAM1), vascular cell adhesion molecule 1 (VCAM1), endothelin 1 (ET-1), von Willebrand factor (vWF), and leucocyte adhesion, and led to reduction in AKT Ser⁴⁷³ and endothelial nitric oxide synthase (eNOS) Ser¹¹⁷⁷ phosphorylation. CONCLUSIONS Our data describe a mechanism by which sFLT1 sensitizes endothelial cells to pro-inflammatory factors, providing an explanation for how placental stress may precipitate the pre-eclamptic syndrome.
Do Molecular Clocks Run at All? A Critique of Molecular Systematics

Although molecular systematists may use the terminology of cladism, claiming that the reconstruction of phylogenetic relationships is based on shared derived states (synapomorphies), the latter is not the case. Rather, molecular systematics is (largely) based on the assumption, first clearly articulated by Zuckerkandl and Pauling (1962), that degree of overall similarity reflects degree of relatedness. This assumption derives from interpreting molecular similarity (or dissimilarity) between taxa in the context of a Darwinian model of continual and gradual change. Review of the history of molecular systematics and its claims in the context of molecular biology reveals that there is no basis for the “molecular assumption. ”
Recognizing the Bank Robber and Spotting the Difference: Emotional State and Global vs. Local Attentional Set

Abstract In two experiments (161 participants in total), we investigated how current mood influences processing styles (global vs. local). Participants watched a video of a bank robbery before receiving a positive, negative or neutral induction, and they performed two tasks: a face-recognition task about the bank robber as global processing measure, and a spot-the-difference task using neutral pictures (Experiment-1) or emotional scenes (Experiment-2) as local processing measure. Results showed that positive mood induction favoured a global processing style, enhancing participants’ ability to correctly identify a face even when they watched the video before the mood-induction. This shows that, besides influencing encoding processes, mood state can be also related to retrieval processes. On the contrary, negative mood induction enhanced a local processing style, making easier and faster the detection of differences between nearly identical pictures, independently of their valence. This dissociation supports the hypothesis that current mood modulates processing through activation of different cognitive styles.
Long term treatment with sodium hyaluronate-containing artificial tears reduces ocular surface damage in patients with dry eye

Background/aims: Several studies have reported that sodium hyaluronate is able to improve both symptoms and signs in patients with dry eye but none have demonstrated an improvement of conjunctival epithelial cell abnormalities of the ocular surface. The aim of this study was to explore the effect of sodium hyaluronate-containing eye drops on the ocular surface of patients with dry eye during long term treatment. Methods: A randomised double blind study was undertaken in 86 patients with medium to severe dry eye (that is, rose bengal and/or fluorescein test score of at least 3, tear film break up time <10 seconds, or Schirmer's test <5.5 mm). Patients were treated with either preservative-free sodium hyaluronate or saline for 3 months at a dose of one drop 4–8 times a day. Bulbar impression cytology, slit lamp examinations, and subjective symptoms were evaluated after 1, 2, and 3 months. Impression cytology was considered the primary efficacy parameter of the study. Results: The efficacy analysis was performed on a total of 44 patients who were able to fully adhere to the protocol. After 3 months of treatment sodium hyaluronate improved impression cytology score (p = 0.024 v baseline). At the same time also the difference with respect to placebo was statistically significant (p = 0.036). Study medication was well tolerated and no treatment related adverse events occurred during the study. Conclusions: Sodium hyaluronate may effectively improve ocular surface damage associated with dry eye syndrome.
conditional expression of Myd 88 ( p . L 252 P ) leads to the development of diffuse large B cell lymphoma in mice

Temperature dependence of the ionization coefficients of Al/sub x/Ga/sub 1-x/As

As Al/sub x/Ga/sub 1-x/As alloys are increasingly used for microwave and millimeter wave power devices and circuits that work under high electric field intensities and junction temperatures; understanding the temperature dependence of impact ionization and related properties in this material system becomes more and more important. Measurements of the multiplication gain and noise of avalanche photodiodes (APDs) provide insight to the avalanche characteristics of semiconductors. Previously, we have reported the characteristics of GaAs and Al/sub 0.2/Ga/sub 0.8/As APD's at room temperature. In this paper, the gain and noise of a series of homojunction Al/sub x/Ga/sub 1-x/As APD's were investigated over a wide temperature range from 29/spl deg/C to 125/spl deg/C, and the temperature dependence of their ionization coefficients was extracted.
