Predicting nose projection and pronasale position in facial approximation: a test of published methods and proposal of new guidelines.

Many prediction guidelines exist in facial approximation for determining the soft-tissue features of the face, and the reliability of each is generally unknown. This study examines four published and commonly used soft-tissue prediction guidelines for estimating nose projection, two of which also estimate the position of the pronasale. The methods tested are those described by: 1) Gerasimov ([1971] The Face Finder; London: Hutchinson & Co.), using the distal third of the nasal bones and the nasal spine; 2) Krogman ([1962] The Human Skeleton in Forensic Medicine; Springfield: Charles C. Thomas), using the average soft-tissue depth at midphiltrum, plus three times the length of the nasal spine (and a variation of this technique: plus three times the distance of the tip of the nasal spine from the nasal aperture); 3) Prokopec and Ubelaker ([2002] Forensic Sci Commun 4:1-4), using the reflected profile line of the nasal aperture; and 4) George ([1987] J Forensic Sci 32:1305-1330), using a variation of the Goode method. Four identical hard-tissue tracings were made of 59 adult lateral head cephlograms (29 males, mean age 24, SD 10 years; 30 females, mean age 23, SD 5 years) on separate sheets of tracing paper. One soft-tissue tracing was also made for each radiograph. All tracings were marked with three identical reference points. Soft-tissue tracings were isolated from one of us (C.N.S.), who attempted under blind conditions to predict pronasale position and nose projection on the hard-tissue tracings, using the soft-tissue prediction guides above. Actual soft-tissue tracings were then compared to each of the predicted tracings, and differences in projection/pronasale position were measured. Results indicate that for nose projection, methods 3 and 4 performed well, while methods 1 and 2 performed poorly. Features which are most related to nose projection/pronasale are described in this paper, as are regression equations generated from these variables that predict pronasale/nose projection better than the traditional methods mentioned above. The results of this study are significant because they: 1) indicate that the popular facial approximation methods used to build the nose are inaccurate and produce incorrect nose anatomy; and 2) indicate that the new pronasale prediction methods developed here appear to have less error than traditional methods.
Is paperless really more?

For the past 20 years, the evolution of the paperless office has been predicted as an inevitable result of technology advances—the fully electronic, high-tech office-of-the-future is just around the corner, according to this thinking. But this prediction doesn't take lessons of history into account. Far from rendering old technologies obsolete, the introduction of new technologies has often stimulated dynamic interactions between old and new. Sometimes, the introduction of new technologies sparks new interest in old ones. Gutenberg's invention of the printing press should have sounded the death knell for handwritten works, for example, yet for several centuries quite the opposite occurred: At the end of the fifteenth century, even though printing was by then well established, care for the elegant hand had not died out, and some of the most memorable examples of calligraphy still lay in the future. While books were becoming more easily available and more people were learning to read, more were also learning to write, often stylishly and with great distinction, and the sixteenth century became not only the age of the printed word but also the century of the great manuals of handwriting. [4] Those who expect new technologies to immediately change the world often forget to take into account the social-material complex of which technologies are only a part [10]. New technologies solve problems , but they also create dilemmas involving social, cultural, organizational , and human factors [5, 6]. Today, the paperless office is more distant than when it was proposed. Despite the enormous popularity of computers and personal digital assistants , along with improvements in screen technology, mobile comput-Rethinking the role of paper in the digital age.
Effect of TV food advertising restriction on food environment for children in South Korea

Summary This study attempted to determine the effects of restrictions on television (TV) food advertising on children's food environments in South Korea. It examined changes that occurred in the marketing mix of food companies following enactment of those restrictions. An on-line survey was conducted with marketers or R&D managers of 108 food companies. A questionnaire was used to inquire about changes that occurred in Product, Place, Price and Promotion as a result of the restrictions placed on TV food advertising. Analysis was performed on the data collected from the responding 63 food companies (58.3%). The results of their answers showed that among the four marketing mix components the restrictions exerted relatively stronger effects on Product. Effects were stronger on companies that produced foods within the product categories of Energy-Dense and Nutrient-Poor foods (EDNP companies) in comparison with companies that did not (non-EDNP companies). The restrictions exerted positive effects on EDNP companies with respect to compliance with labeling requirements and reinforcement of nutritional contents examination, as well as changes to products such as reducing unhealthy ingredients and fortifying nutrients. Overall, the results revealed the possibility that restrictions on TV food advertising could improve children's food environments by encouraging EDNP companies to make favorable product changes. On the one hand, the results also found that some food companies attempted to bypass the regulations by changing marketing channels from TV to others and by reducing product serving sizes. Thus, future measures should be implemented to prevent food companies from bypassing regulations and to control children's exposure to marketing channels other than TV.
Neither a zinc supplement nor phytate-reduced maize nor their combination enhance growth of 6- to 12-month-old Guatemalan infants.

After age 6 mo, the combination of breast-feeding and unfortified plant-based complementary feeding provides inadequate zinc (Zn). Additionally, high phytate intakes compromise the bioavailability of zinc. Our principal objective in this randomized controlled, doubly masked trial was to determine the effect of substituting low-phytate maize, a daily 5-mg zinc supplement, or both, in infants between ages 6-12 mo on impaired linear growth velocity, a common feature of zinc deficiency. In the Western Highlands of Guatemala, 412 infants were randomized to receive low-phytate or control maize. Within each maize group, infants were further randomized to receive a zinc supplement or placebo. Length, weight, and head circumference were measured at 6, 9, and 12 mo of age. There were no significant differences between the 2 maize groups or between the Zn supplement and placebo groups and no treatment interaction was observed for length-for-age (LAZ), weight-for-length (WLZ) or head circumference Z-scores. Overall mean (+/- SD) Z-scores at 6 mo for combined treatment groups were: LAZ, -2.1 +/- 1.1; WLZ, 0.7 +/- 1.0; and head circumference Z-score, -0.7. 0 +/- 1.0. At 12 mo, these had declined further to: LAZ, -2.5 +/- 1.1; WLZ, -0.0 +/- 0.9; and head circumference Z-score, -0.9 +/- 1.1; 83.3% were stunted and 2% were wasted. Low linear growth in older Guatemalan infants was not improved with either low-phytate maize or a daily 5-mg zinc supplement. Low contribution of maize to the complementary food of the infants negated any potential advantage of feeding low-phytate maize.
Intracellular beta-blockade: overexpression of Galpha(i2) depresses the beta-adrenergic response in intact myocardium.

OBJECTIVE Increased levels of inhibitory G proteins have been observed in heart failure, but their physiological relevance in mediating the reduced beta-adrenergic response is largely unknown. METHODS To evaluate the functional consequences of Galpha(i2) overexpression, we studied myocardial contraction in intact isometric contracting cardiac rabbit trabeculae and isolated myocytes after adenovirus-mediated gene transfer of Galpha(i2). RESULTS Neither Galpha(i2) nor lacZ (control) overexpression altered baseline contractile force. After 72 h of continuous contractions, developed force (F(dev)) increased after addition of 1 microM isoproterenol by 28.5+/-9.7 mN/mm(2) in the control group, which was unchanged from the initial response at t=0 h (23.7+/-3.8 mN/mm(2)). In sharp contrast, in preparations transfected with AdGalpha(i2), the response to isoproterenol was significantly attenuated (5.9+/-2.0 vs. 27.6+/-4.2 mN/mm(2), t=72 vs. 0 h, respectively, P<0.01). In a primary culture of transfected isolated myocytes from a nearly identical baseline, isoproterenol increased cell shortening by 3.1+/-0.6% in the lacZ transfected myocytes, but only by 1.3+/-0.5% in Galpha(i2) transfected myocytes (t=72 h, P<0.01). In Galpha(i2) transfected myocytes, pertussis toxin restored beta-adrenergic responsiveness, indicating specificity of attenuation by the transgene. CONCLUSIONS Overexpression of Galpha(i2) attenuates the positive inotropic effects of beta-adrenergic stimulation in myocardium. In addition, the method we developed allows investigation of a causal link between altered protein expression and subsequent alterations in contractile function in a physiological relevant in vitro manner.
Effects of Divorce on Children of Different Ages: A Descriptive Study.

Comparisons among age groups (pre-school through young adult) and among studies completed in recent decades demonstrate variations in family structure and social attitudes in a changing world. The principal impact of divorce on children, as seen in this context, reveals that the effects vary not only by age but by era. Particular attention is paid in this research to adolescent and young adult children of divorce. 1

La presencia del distractor tuvo un efecto significativo sobre el numero de aciertos acumulados, considerandose como un estimulo interferente capaz de afectar la memoria de trabajo en adultos mayores.
Recent progress on Liouville Field Theory

An explicit construction for the monodromy of the Liouville conformal blocks in terms of Racah-Wigner coefficients of the quantum group U_q(sl(2,R)) is proposed. As a consequence, crossing-symmetry for four point functions is analytically proven, and the expression for the correlator of three boundary operators is obtained.
Easy as Pi: A Network Coding Raspberry Pi Testbed

In the near future, upcoming communications and storage networks are expected to tolerate major difficulties produced by huge amounts of data being generated from the Internet of Things (IoT). For these types of networks, strategies and mechanisms based on network coding have appeared as an alternative to overcome these difficulties in a holistic manner, e.g., without sacrificing the benefit of a given network metric when improving another. There has been recurrent issues on: (i) making large-scale deployments akin to the Internet of Things; (ii) assessing and (iii) replicating the obtained results in preliminary studies. Therefore, finding testbeds that can deal with large-scale deployments and not lose historic data in order to evaluate these mechanisms are greatly needed and desirable from a research perspective. However, this can be hard to manage, not only due to the inherent costs of the hardware, but also due to maintenance challenges. In this paper, we present the required key steps to design, setup and maintain an inexpensive testbed using Raspberry Pi devices for communications and storage networks with network coding capabilities. This testbed can be utilized for any applications requiring results replicability.
Stem cells: attributes, cycles, spirals, pitfalls and uncertainties. Lessons for and from the crypt.

We consider some of the problems involved in current discussions on stem cells in adult mammalian tissues. The present concepts involve a number of pitfalls, weaknesses and logical, semantic and classification problems. This indicates the necessity for new and well-defined concepts that are amenable to experimental analysis. One of the major difficulties in considering stem cells is that they are defined in terms of their functional capabilities which can only be assessed by testing the abilities of the cells, which itself may alter their characteristics during the assay procedure: a situation similar to the uncertainty principle in physics. The terms that describe stem cell functions are often not well defined and are used loosely, which can lead to confusion. If such context-dependent interactions exist between the manipulation and measurement process and the challenged stem cells, the question of, for example, the number of stem cells, in a tissue has to be posed in a new way. Rather than obtaining a single number one might end up with various different numbers under different circumstances, all being complementary. This might suggest that stemness is not a property but a spectrum of capabilities from which to choose. This concept might facilitate a reconciliation between the different and sometimes opposing experimental results. Given certain experimental evidence, we have attempted to provide a novel concept to describe structured cell populations in tissues involving stem cells, transit cells and mature cells. It is based on the primary assumption that the proliferation and differentiation/maturation processes are in principle independent entities in the sense that each may proceed without necessarily affecting the other. Stem cells may divide without maturation while cells approaching functional competence may mature but do not divide. In contrast, transit cells divide and mature showing intermediate properties between stem cells and mature functional cells. The need to describe this transition process and the variable coupling between proliferation and maturation leads us to formulate a spiral model of cell and tissue organisation. This concept is illustrated for the intestinal epithelium. It is concluded that the small intestinal crypts contain 4-16 actual stem cells in steady state but up to 30-40 potential stem cells (clonogenic cells) which may take over stem cell properties following perturbations. This implies that transit cells can under certain circumstances behave like actual stem cells while they undergo maturation under other conditions. There is also evidence that the proliferation and differentiation/maturation processes are subject to controls that ultimately lead to a change in the spiral trajectories.

The bright side of psychoactive substances: cannabinoid-based drugs in motor diseases

ABSTRACT Introduction: Psychoactive substances are associated with the idea of drugs with high addictive liability, affecting mental states, cognition, emotion and motor behavior. However these substances can modify synaptic transmission and help to disclose some mechanisms underlying alterations in brain processing and pathophysiology of motor disease. Hence, the ‘bright side’ of e cannabinoid-based drugs must be thoroughly examined to be identified within the latter framework. Areas covered: We will analyze the preclinical and clinical evidence of cannabinoid-based drugs, discussing their therapeutic value in basal ganglia motor disorders such as Parkinson’s disease and Huntington disease. Expert commentary: Despite the knowledge acquired in the last years, the therapeutic potential of cannabinoid-based drugs should be further tested by novel routes of investigation. This should be focused on the role of cannabinoid signaling system in mitochondrial function as well as on the physical and functional interaction with other key receptorial targets belonging to this network.
Reversible Oligohydramnios in a Pregnancy with Angiotensin-Converting Enzyme Inhibitor Exposure

The use of angiotensin-converting enzyme inhibitors during pregnancy has been associated with poor fetal outcomes, including oligohydramnios, renal tubular dysplasia, cranial malformations, and fetal death. A 35-year-old woman with chronic hypertension was treated with the angiotensin-converting enzyme inhibitor benazepril until 27 weeks' gestation, when severe oligohydramnios was noted. After hospitalization for bed rest, fetal surveillance, and discontinuation of the agent, amniotic fluid rapidly reaccumulated, and a healthy infant was delivered at term. Although the use of angiotensin-converting enzyme inhibitors should be avoided during pregnancy, patients whose fetuses are inadvertently exposed in utero need not be given a uniformly poor prognosis. Oligohydramnios induced by the use of angiotensin-converting enzyme inhibitors during pregnancy may be reversible if the agent is discontinued. This case underscores the need for obstetricians to review carefully the medication regimens of all pregnant women and to be familiar with generic and proprietary names of medications to avoid the use of potentially harmful agents during pregnancy.
Genome-Scale Reconstruction of the Human Astrocyte Metabolic Network

Astrocytes are the most abundant cells of the central nervous system; they have a predominant role in maintaining brain metabolism. In this sense, abnormal metabolic states have been found in different neuropathological diseases. Determination of metabolic states of astrocytes is difficult to model using current experimental approaches given the high number of reactions and metabolites present. Thus, genome-scale metabolic networks derived from transcriptomic data can be used as a framework to elucidate how astrocytes modulate human brain metabolic states during normal conditions and in neurodegenerative diseases. We performed a Genome-Scale Reconstruction of the Human Astrocyte Metabolic Network with the purpose of elucidating a significant portion of the metabolic map of the astrocyte. This is the first global high-quality, manually curated metabolic reconstruction network of a human astrocyte. It includes 5,007 metabolites and 5,659 reactions distributed among 8 cell compartments, (extracellular, cytoplasm, mitochondria, endoplasmic reticle, Golgi apparatus, lysosome, peroxisome and nucleus). Using the reconstructed network, the metabolic capabilities of human astrocytes were calculated and compared both in normal and ischemic conditions. We identified reactions activated in these two states, which can be useful for understanding the astrocytic pathways that are affected during brain disease. Additionally, we also showed that the obtained flux distributions in the model, are in accordance with literature-based findings. Up to date, this is the most complete representation of the human astrocyte in terms of inclusion of genes, proteins, reactions and metabolic pathways, being a useful guide for in-silico analysis of several metabolic behaviors of the astrocyte during normal and pathologic states.
Angiotensin II mediates downregulation of aquaporin water channels and key renal sodium transporters in response to urinary tract obstruction.

The renin-angiotensin system is well known to be involved in the pathophysiological changes in renal function after obstruction of the ureter. Previously, we demonstrated that bilateral ureteral obstruction (BUO) is associated with dramatic changes in the expression of both renal sodium transporters and aquaporin water channels (AQPs). We now examined the effects of the AT(1)-receptor antagonist candesartan on the dysregulation of AQPs and key renal sodium transporters in rats subjected to 24-h BUO and followed 2 days after release of BUO (BUO-2R). Consistent with previous observations, BUO-2R resulted in a significantly decreased expression of AQP1, -2, and -3 compared with control rats. Concomitantly, the rats developed polyuria and reduced urine osmolality. Moreover, expression of the type 2 Na-phosphate cotransporter (NaPi-2) and type 1 bumetanide-sensitive Na-K-2Cl cotransporter (NKCC2) was markedly reduced, consistent with postobstructive natriuresis. Candesartan treatment from the onset of obstruction attenuated the reduction in GFR (3.1 +/- 0.4 vs. 1.7 +/- 0.3 ml.min(-1). kg(-1)) and partially prevented the reduction in the expression of AQP2 (66 +/- 21 vs. 13 +/- 2%, n = 7; P < 0.05), NaPi-2 (84 +/- 6 vs. 57 +/- 10%, n = 7; P < 0.05), and NKCC2 (89 +/- 12 vs. 46% +/- 11, n = 7; P < 0.05). Consistent with this, candesartan treatment attenuated the increase in urine output (58 +/- 4 vs. 97 +/- 5 microl.min(-1). kg(-1), n = 7; P < 0.01) and the reduction in sodium reabsorption (433 +/- 62 vs. 233 +/- 45 micromol.min(-1). kg(-1), n = 7; P < 0.05) normally found in rats subjected to BUO. Moreover, candesartan treatment attenuated induction of cyclooxygenase 2 (COX-2) expression in the inner medulla, suggesting that COX-2 induction in response to obstruction is regulated by ANG II. In conclusion, candesartan prevents dysregulation of AQP2, sodium transporters, and development of polyuria seen in BUO. This strongly supports the view that candesartan protects kidney function in response to urinary tract obstruction.
Efficient Activity Retrieval through Semantic Graph Queries

We present an efficient retrieval approach for activity detection in large surveillance video datasets based on semantic graph queries. Unlike conventional approaches, our zero-shot retrievalmethod does not require knowledge of the activity classes contained in the video. We propose a novel user-centric approach thatmodels queries through the creation of sparse semantic graphs based on attributes and discriminative relationships. We then pose search as a ranked subgraph matching problem and leverage the fact that the attributes and relationships in the query have different levels of discriminability to filter out bad matches. Rather than solving the NP-hard exact subgraph matching problem, we develop a novel maximally discriminative spanning tree (MDST) as the relaxation of a given query graph, and then describe a matching algorithm that recovers matches to this tree in linear time using maximally discriminative subgraphmatching (MDSM). We utilize theMDST tominimize the number of possible matches to the original query while guaranteeing that the best matches are within this set. We test this algorithm on two large video datasets: the 35-GB Virat Ground dataset and a 1-TB aerial data collection from Yuma. These datasets yield graphs with 200,000 nodes and 1 million nodes, respectively, with an average degree of 5. Our approach finds complex, large-scale queries in seconds while maintaining comparable precision and recall to slower current approaches.
