Biochemically the defect of the Brindled allelic mutant of the Mottled mouse and of Menkes' disease in man are very similar if not identical. A modification of a normal Cu-binding protein or an unrestrained synthesis of a Cu-binding protein that normally is present only in small amounts is proposed as the basis of this disease

Automated reasoning in man-machine control systems

Stratton, R.C.; Lusk, E.L.

1983-01-01

This paper describes a project being undertaken at Argonne National Laboratory to demonstrate the usefulness of automated reasoning techniques in the implementation of a man-machine control system being designed at the EBR-II nuclear power plant. It is shown how automated reasoning influences the choice of optimal roles for both man and machine in the system control process, both for normal and off-normal operation. In addition, the requirements imposed by such a system for a rigorously formal specification of operating states, subsystem states, and transition procedures have a useful impact on the analysis phase. The definitions and rules are discussed for a prototype system which is physically simple yet illustrates some of the complexities inherent in real systems

Acute urinary retention in a young man secondary to colonic irrigation: a case report

Directory of Open Access Journals (Sweden)

2009-06-01

Full Text Available Abstract Introduction Autonomic innervation of the bladder is complex and regulated by a hierarchy of mechanisms of the central nervous system. Any dysfunction in these regulatory mechanisms can lead to acute urinary retention. Case presentation A 36-year-old Caucasian man presented with acute urinary retention following extensive bowel irrigation. His urinary bladder was decompressed and his normal voiding mechanism was restored thereafter. Conclusion We postulate that prolonged anorectal and sigmoid dilatation can stimulate the recto-vesicourethral reflex and lead to acute urinary retention via autonomic dysfunction.

Normal and abnormal distribution of the adrenomedullary imaging agent m-[I-131]iodobenzylguanidine (I-131 MIBG) in man; evaluation by scintigraphy

1983-01-01

The scintigraphic distribution of m-[ 131 I]iodobenzylguanidine (I-131 MIBG), an adrenal medullary imaging agent, was studied to determine the patterns of uptake of this agent in man. The normal distribution of I-131 MIBG includes clear portrayal of the salivary glands, liver, spleen, and urinary bladder. The heart, middle and lower lung zones, and colon were less frequently or less clearly seen. The upper lung zones and kidneys were seldom visualized. The thyroid appeared only in cases of inadequate thyroidal blockade. The normal adrenal glands were seldom seen and faintly imaged in 2% at 24 h after injection and in 16% at 48 h, in patients shown not to have pheochromocytomas, whereas intra-adrenal, extra-adrenal, and malignant pheochromocytomas usually appeared as intense focal areas of I-131 MIBG uptake at 24 through 72 h

The purpose of the present study was to compare children with a cochlear implant and normal hearing children on aspects of emotion regulation (emotion expression and coping strategies) and social functioning (social competence and externalizing behaviors) and the relation between emotion regulation and social functioning. Participants were 69 children with cochlear implants (CI children) and 67 normal hearing children (NH children) aged 1.5-5 years. Parents answered questionnaires about their children's language skills, social functioning, and emotion regulation. Children also completed simple tasks to measure their emotion regulation abilities. Cochlear implant children had fewer adequate emotion regulation strategies and were less socially competent than normal hearing children. The parents of cochlear implant children did not report fewer externalizing behaviors than those of normal hearing children. While social competence in normal hearing children was strongly related to emotion regulation, cochlear implant children regulated their emotions in ways that were unrelated with social competence. On the other hand, emotion regulation explained externalizing behaviors better in cochlear implant children than in normal hearing children. While better language skills were related to higher social competence in both groups, they were related to fewer externalizing behaviors only in cochlear implant children. Our results indicate that cochlear implant children have less adequate emotion-regulation strategies and less social competence than normal hearing children. Since they received their implants relatively recently, they might eventually catch up with their hearing peers. Longitudinal studies should further explore the development of emotion regulation and social functioning in cochlear implant children. Copyright © 2012 Elsevier Ireland Ltd. All rights reserved.

The weight of organs from autopsy cases of normal Japanese adults, children, and infants is presented for the purpose of approaching a Reference Japanese Man. The skeletal content and the daily intake of alkaline earth elements are given. A lower rate of transfer (K 2 ) to the thyroid gland of ingested radioiodine, as well as a remarkably shorter biological half-life than the data adopted by ICRP, is also proved as a result of this study.

It is necessary to set up real-time hardware-in-loop simulation system for power regulation of nuclear heating reactor (NHR) because it is used in the load following instance such as seawater desalination and energy source. As the experiment data are so large that it is hard to be real-time all in one computer and to save and show the data.With the distributed configuration, the system was set up having a legible and intuitionist man-machine interface, speeding the model calculation computer and meeting the requirements of power regulation of NHR. Screen clear and concise, easy command input and results output make the system easier to verify. (authors)

The scintigraphic distribution of m-[ 131 I]iodobenzylguanidine (I- 131 MIBG), an adrenal medullary imaging agent, was studied to determine the patterns of uptake of this agent in man. The normal distribution of I- 131 MIBG includes clear portrayal of the salivary glands, liver, spleen, and urinary bladder. The heart, middle and lower lung zones, and colon were less frequently or less clearly seen. The upper lung zones and kidneys were seldom visualized. The thyroid appeared only in cases of inadequate thyroidal blockade. The ''normal'' adrenal glands were seldom seen and faintly imaged in 2% at 24 hr after injection and in 16% at 48 hr, in patients shown not to have pheochromocytomas, whereas intra-adrenal, extraadrenal, and malignant pheochromocytomas usually appeared as intense focal areas of I- 131 MIBG uptake at 24 through 72 hr

Reference Man as defined and described in ICRP Publication 23 is in the process of major revision, with an emphasis on the age and sex, and characteristics of non-European populations. Japanese Reference Man (or Woman) is to be defined as the subject, normal and healthy, 20 to 30 years of age, who inhabits in Japan and live on the 'standard diet'. He (or she) is a Mongoloid in race, and 170 (or 160) cm in height, and 60 (or 51) kg in weight. Physical properties such as masses of 114 organs, tissues and components, and their specific gravities of Japanese Reference Male are given. Body composition or body fat, LBM, skeleton, soft lean body mass (SLBM), body water, blood, muscle, ash, protein and specific gravity were also given as well as body surface. These data are primarily based on the data obtained for normal Japanese, and, where data unavailable, they were derived from ICRP Reference Man data by using a new concept of SLBM. Red bone marrow was estimated to be 1,000g as compared to 1,500g in Reference Man. Body fat was obtained by using Nagamine's equations, which showed a recent slight tendency of obesity. In conclusion, the present data for Japanese Reference Man could be used in designing appropriate phantoms, mathematical and real, for Japanese. Japanese Reference Man will also provide a basis for Asian Reference Man, which, in principle, should be consistent with ICRP concepts of Reference Man. (author)

The extent of man from Vitruvius to Marfan.

Science.gov (United States)

Schott, G D

It is frequently stated that patients with Marfan's syndrome have an arm span greater than height. This implies a characteristic different from the proportions in normal adult man, in whom span and height are often thought to be equal. Such equality of span and height, which allows man to be portrayed within a square, has been a widely held concept, immortalised by Leonardo da Vinci, that dates from the Roman Vitruvius. However, in the past two hundred years, anthropometry has shown that span exceeds height in 59-78% of normal adult white men. Thus not only is the classic concept of equality of span and height generally incorrect, but also a span greater than height cannot be considered characteristic of Marfan's syndrome. Paradoxically, in some affected individuals, Vitruvian equality of height and span may occur.

Quantitative radiation dose-response relationships for normal tissues in man - I. Gustatory tissues response during photon and neutron radiotherapy

International Nuclear Information System (INIS)

Mossman, K.L.

1982-01-01

Quantitative radiation dose-response curves for normal gustatory tissue in man were studied. Taste function, expressed as taste loss, was evaluated in 84 patients who were given either photon or neutron radiotherapy for tumors in the head and neck region. Patients were treated to average tumor doses of 6600 cGy (photon) or 2200 cGy intervals for photon patients and 320-cGy intervals for neutron patients during radiotherapy. The dose-response curves for photons and neutrons were analyzed by fitting a four-parameter logistic equation to the data. Photon and neutron curves differed principally in their relative position along the dose axis. Comparison of the dose-response curves were made by determination of RBE. At 320 cGy, the lowest neutron dose at which taste measurements were made, RBE = 5.7. If this RBE is correct, then the therapeutic gain factor may be equal to or less than 1, indicating no biological advantage in using neutrons over photons for this normal tissue. These studies suggest measurements of taste function and evaluation of dose-response relationships may also be useful in quantitatively evaluating the efficacy of chemical modifiers of radiation response such as hypoxic cell radiosensitizers and radioprotectors

We characterised the diastolic pressure-flow velocity relationship in the normal left coronary artery of conscious man before and after vasodilatation with angiographic contrast medium. Phasic coronary artery pressure and flow velocity were measured in ten patients during individual diastoles (0.5 to 1.0 s) using a 20 MHz catheter-tipped, pulsed Doppler transducer. All pressure-flow velocity curves were linear over the diastolic pressure range of 110 +/- 15 (SD) mmHg to 71 +/- 7 mmHg (r = 0.97 +/- 0.01). In the basal state, values for slope and extrapolated zero flow pressure intercept averaged 0.35 +/- 0.12 cm X s-1 X mmHg-1 and 51.7 +/- 8.6 mmHg, respectively. Vasodilatation resulted in a 2.5 +/- 0.5 fold increase in mean flow velocity. The diastolic pressure-flow velocity relationship obtained during peak vasodilatation compared to that during basal conditions was characterised by a steeper slope (0.80 +/- 0.48 cm X s-1 X mmHg-1, p less than 0.001) and lower extrapolated zero flow pressure intercept (37.9 +/- 9.8 mmHg, p less than 0.05). Mean right atrial pressure for the group averaged 4.4 +/- 1.7 mmHg, while left ventricular end-diastolic pressure averaged 8.7 +/- 2.8 mmHg. These observations in man are similar to data reported in the canine coronary circulation which are consistent with a vascular waterfall model of diastolic flow regulation. In this model, coronary blood flow may be regulated by changes in diastolic zero flow pressure as well as in coronary resistance.

This report consolidates research carried out at Clemson University and Stanford University where a series of measurements were undertaken to identify the man-made radiation present in four bands used by rather different services, namely, L1 Band (1563.42 1587.42 MHz), the Unified S-Band (2025 2110 MHz), the 2.4 GHz Industrial, Scientific and Medical (ISM) Band (2400 2482.50 MHz), and the 23.6-24.0 GHz Passive Sensing Band. Results show that there were distinctive differences in the measurement data in the frequency bands, which should be expected based on the function/regulation associated with each. The GPS L1 Band had little to none terrestrial man-made sources, but the ISM 2.4 GHz Band had a large number of man-made sources regardless of the site and the time. The Unified S Band showed mixed results depending on the sites. The Passive Sensing Band does not contain appreciable man-made radiation.

Full Text Available Brain iron is tightly regulated by a multitude of proteins to ensure homeostasis. Iron dyshomeostasis has become a molecular signature associated with aging which is accompanied by progressive decline in cognitive processes.

Some consideration of Japanese standard man value

International Nuclear Information System (INIS)

Yoshizawa, Yasuo; Kusama, Tomoko

1976-01-01

Numerical values of standard man or reference man is important problem in the field of radiation protection and safety. The standard man values given by ICRP were obtained from European and North American adult data. For that reason, there are some theoretical problems in the application of standard man values to Japanese. The purpose of the present paper is to consider the difference of values between Japanese and standard man. The standard man values are divided into three categories. The first category is the size and weight of the body or organ, the second is the values of elementary composition, and the third is the numerical factors related to metabolic kinetics. It is natural that some values of the second and the third categories have little difference between Japanese and European. On the other hand, there are some differences in the value of the first category, but the differences can calculation in proportional allotment to the body weight. The values concerning the thyroid gland and iodine metabolism are important for radiation protection. It has been foreseen that these values of Japanese are significantly different from standard man. A survey of past reports was carried out with a view to search for normal values of the weight, iodine content, and iodine uptake rate of the thyroid of Japanese. The result of the survey showed that the weight of thyroid are about 19g for adult male and 17g for adult female and that the iodine contents are 12-22mg and iodine uptake rate (fw) is about 0.2.

1983-10-01

We are presently participating in a program to optimize the functional man-machine interface for Liquid Metal-Cooled Fast Breeder Reactors. The overall objective of this program is to enhance operational safety; that is, to accommodate plant incidents through optimal integration of man and machine in performing the functions required to safely control a plant during both normal and off-normal conditions. Purpose of this talk is to describe an approach to determine the optimal roles of man and computer in the control of nuclear power plants. Purpose of this session was to get together people that are working in the areas of understanding of how operators control plants, and working on developing new aids for these operators. We were asked to explain how our modeling and approach we're taking will lead us to an optimization of the roles of the man and the computer in the control of nuclear power plants. Our emphasis was to be on the functions required for plant control, and how the attributes of the human operator and the attributes of the computer can be optimally used to enhance operational safety in performing these functions

Man machine interface and its implementation

Sizewell B is the latest nuclear power station to be constructed in the United Kingdom: its Man-Machine Interfaces are therefore, by definition, the state-of-the-art. This paper discusses the principal Man-Machine Interfaces used in the operation of the station, and the systems that implement them. The Man-Machine Interface facilities discussed are: in the Main Control Room, which is used for normal operation and shutdown of the plant: in the Auxiliary Shutdown Room, which allows shutdown of the reactor if evacuation of the main Control Room is necessary: and in the Technical Support Centre, which is used for remote monitoring of the plant. The Man-Machine Interfaces that are described are parts of a station-wide group of interlinked computer systems called the Data Processing and Control System. This system collects data from the plant and displays it to the operators via discrete devices and on graphical computer displays. It also acquires control inputs from the operators via switches, which are then used to provide remote manual control, modulating control and sequence control. The computer system that handles the plant process data and alarm information displays uses a windowing interface with keyboard and trackerball navigation to allow easy retrieval and viewing of information. It is this system that is the main topic of this paper. (author)

Biogenic amines as regulators of the proliferative activity of normal and neoplastic intestinal epithelial cells (review).

Science.gov (United States)

Tutton, P J; Barkla, D H

1987-01-01

The role of extracellular amines such as noradrenaline and serotonin and their interaction with cyclic nucleotides and intracellular polyamines in the regulation of intestinal epithelial cell proliferation is reviewed with particular reference to the differences between normal and neoplastic cells. In respect to the normal epithelium of the small intestine there is a strong case to support the notion that cell proliferation is controlled by, amongst other things, sympathetic nerves. In colonic carcinomas, antagonists for certain serotonin receptors, for histamine H2 receptors and for dopamine D2 receptors inhibit both cell division and tumour growth. Because of the reproducible variations between tumour lines in the response to these antagonists, this inhibition appears to be due to a direct effect on the tumour cells rather than an indirect effect via the tumour host or stroma. This conclusion is supported by the cytocidal effects of toxic congeners of serotonin on the tumour cells. The most salient difference between the amine responses of normal and neoplastic cells relates to the issue of amine uptake. Proliferation of crypt cells is promoted by amine uptake inhibitors, presumably because they block amine re-uptake by the amine secreting cells--sympathetic neurones and enteroendocrine cells. However, tumour cell proliferation is strongly inhibited by amine uptake inhibitors, suggesting that neoplastic cells can, and need to take up the amine before being stimulated by it. Recent revelations in the field of oncogenes also support an important association between amines, cyclic nucleotides and cell division. The ras oncogenes code for a protein that is a member of a family of molecules which relay information from extracellular regulators, such as biogenic amines, to the intracellular regulators, including cyclic nucleotides. Evidence is presented suggesting that enteroendocrine cells, enterocytes, carcinoid tumour cells and adenocarcinoma cells all have the same

To report the first live births of male infants resulting from intracytoplasmic sperm injection (ICSI) using spermatozoa from a man with Eagle-Barrett syndrome (EBS). Case report. Assisted conception unit within a private hospital. An infertile couple. An infertile couple received repeated treatment with ICSI. Clinical pregnancy and a normal live birth. In 2008, after microinjection of ten oocytes, the transfer of a single expanded blastocyst led to the premature birth of a morphologically normal male infant at 18 weeks' gestation. This outcome followed preterm rupture of membranes and possible cervical incompetence. In 2009, after microinjection of six oocytes, transfer of a single 5-cell embryo led to a singleton pregnancy, with emergency cervical cerclage being performed at 21 weeks. A healthy male infant was born at 30 weeks, with no evidence of EBS, by lower-segment cesarean section for breech presentation and premature labor. In 2012, after elective laparoscopic placement of cervical suture, microinjection of ten oocytes and transfer of a single 4-cell embryo led to a singleton pregnancy with a healthy male infant, with no evidence of EBS, being born by cesarean section at 38 weeks. This report suggests that EBS is not transmitted to male offspring via ICSI. Crown Copyright © 2013. Published by Elsevier Inc. All rights reserved.

Kinetic analysis of zinc metabolism and its regulation in normal humans

Wastney, M.E.; Aamodt, R.L.; Rumble, W.F.; Henkin, R.I.

1986-01-01

Zinc metabolism was studied in 32 normal volunteers after oral or intravenous administration of 65 Zn. Data were collected from the blood, urine, feces, whole body, and over the liver and thigh regions for 9 mo while the subjects consumed their regular diets (containing 10 mg Zn ion/day) and for an additional 9 mo while the subjects received an exogenous oral supplement of 100 mg Zn ion/day. Data from each subject were fitted by a compartmental model for zinc metabolism that was developed previously for patients with taste and smell dysfunction. These data from normal subjects were used to determine the absorption, distribution, and excretion of zinc and the mass of zinc in erythrocytes, liver, thigh, and whole body. By use of additional data obtained from the present study, the model was refined further such that a large compartment, which was previously determined to contain 90% of the body zinc, was subdivided into two compartments to represent zinc in muscle and bone. When oral zinc intake was increased 11-fold three new sites of regulation of zinc metabolism were identified in addition to the two sites previously defined in patients with taste and smell dysfunction (absorption of zinc from gut and excretion of zinc in urine). The three new sites are exchange of zinc with erythrocytes, release of zinc by muscle, and secretion of zinc into gut. Regulation at these five sites appears to maintain some tissue concentrations of zinc when dietary zinc increases

Normal dietary levels of radium-226, radium-228, lead-210, and polonium-210 for man

Holtzman, R.B.

1980-01-01

A review of the literature and the results of some recent measurements on the levels in man's diet of the naturally occurring radionuclides 226 Ra, 228 Ra, 210 Pb, and 210 Po are presented. Intakes in other countries are similar to those in the United States, but in localized populations the 226 Ra intake can be 8 or more pCi/day. The few data on 228 Ra show that intake of this nuclide is about 80% that of 226 Ra except in monazite areas where intakes of up to 160 pCi 228 Ra/day are reported. Drinking water contributes less than 5% to daily intake except in special areas. For 210 Pb, higher levels have been noted for Germany and the Union of Soviet Socialist Republics than for the United States. Persons in the Arctic who consume reindeer or caribou meat may ingest 210 Pb at the rate of 10 to 40 pCi/day. Normal dietary levels of 210 Po are about 20 to 30% higher than those of 210 Pb, except in the Arctic. The levels of these nuclides in classes of foods are compared to show that the higher levels observed in certain diets are due to the levels in particular foods. Because of the high levels of 210 Pb intake in Japan, total skeletal dose rates in that country are estimated to be more than twice those in the United States. The use of dietary intake for estimating metabolic parameters, such as intestinal absorption of 226 Ra and 210 Pb, is discussed

Abstraction of man-made shapes

Man-made objects are ubiquitous in the real world and in virtual environments. While such objects can be very detailed, capturing every small feature, they are often identified and characterized by a small set of defining curves. Compact, abstracted shape descriptions based on such curves are often visually more appealing than the original models, which can appear to be visually cluttered. We introduce a novel algorithm for abstracting three-dimensional geometric models using characteristic curves or contours as building blocks for the abstraction. Our method robustly handles models with poor connectivity, including the extreme cases of polygon soups, common in models of man-made objects taken from online repositories. In our algorithm, we use a two-step procedure that first approximates the input model using a manifold, closed envelope surface and then extracts from it a hierarchical abstraction curve network along with suitable normal information. The constructed curve networks form a compact, yet powerful, representation for the input shapes, retaining their key shape characteristics while discarding minor details and irregularities. © 2009 ACM.

Hydrophobic Man-1-P derivatives correct abnormal glycosylation in Type I congenital disorder of glycosylation fibroblasts.

Patients with Type I congenital disorders of glycosylation (CDG-I) make incomplete lipid-linked oligosaccharides (LLO). These glycans are poorly transferred to proteins resulting in unoccupied glycosylation sequons. Mutations in phosphomannomutase (PMM2) cause CDG-Ia by reducing the activity of PMM, which converts mannose (Man)-6-P to Man-1-P before formation of GDP-Man. These patients have reduced Man-1-P and GDP-Man. To replenish intracellular Man-1-P pools in CDG-Ia cells, we synthesized two hydrophobic, membrane permeable acylated versions of Man-1-P and determined their ability to normalize LLO size and N-glycosylation in CDG-Ia fibroblasts. Both compounds, compound I (diacetoxymethyl 2,3,4,6-tetra-O-acetyl-alpha-D-mannopyranosyl phosphate) (C-I) and compound II (diacetoxymethyl 2,3,4,6-tetra-O-ethyloxycarbonyl-alpha-D-mannopyranosyl phosphate) (C-II), contain two acetoxymethyl (CH2OAc) groups O-linked to phosphorous. C-I contains acetyl esters and C-II contains ethylcarbonate (CO2Et) esters on the Man residue. Both C-I and C-II normalized truncated LLO, but C-II was about 2-fold more efficient than C-I. C-II replenished the GDP-Man pool in CDG-Ia cells and was more efficiently incorporated into glycoproteins than exogenous Man at low concentrations (25-75 mM). In a glycosylation assay of DNaseI in CDG-Ia cells, C-II restored glycosylation to control cell levels. C-II also corrected impaired LLO biosynthesis in cells from a Dolichol (Dol)-P-Man deficient patient (CDG-Ie) and partially corrected LLO in cells from an ALG12 mannosyltransferase-deficient patient (CDG-Ig), whereas cells from an ALG3-deficient patient (CDG-Id) and from an MPDU1-deficient patient (CDG-If) were not corrected. These results validate the general concept of using pro-Man-1-P substrates as potential therapeutics for CDG-I patients.

In renal failure, hyperphosphatemia occurs despite a marked elevation in serum fibroblast growth factor (FGF)-23. Abnormal regulation of the FGFR1-Klotho receptor complex may cause a resistance to the phosphaturic action of FGF23. The purpose of the present study was to investigate the regulation of renal Klotho and FGF receptor (FEFR)-1 in healthy and uremic rats induced by 5/6 nephrectomy. In normal rats, the infusion of rat recombinant FGF23 enhanced phosphaturia and increased renal FGFR1 expression; however, Klotho expression was reduced. Uremic rats on a high-phosphate (HP) diet presented hyperphosphatemia with marked elevation of FGF23 and an increased fractional excretion of phosphate (P) that was associated with a marked reduction of Klotho expression and an increase in FGFR1. After neutralization of FGF23 by anti-FGF23 administration, phosphaturia was still abundant, Klotho expression remained low, and the FGFR1 level was reduced. These results suggest that the expression of renal Klotho is modulated by phosphaturia, whereas the FGFR1 expression is regulated by FGF23. Calcitriol (CTR) administration prevented a decrease in renal Klotho expression. In HEK293 cells HP produced nuclear translocation of β-catenin, together with a reduction in Klotho. Wnt/β-catenin inhibition with Dkk-1 prevented the P-induced down-regulation of Klotho. The addition of CTR to HP medium was able to recover Klotho expression. In summary, high FGF23 levels increase FGFR1, whereas phosphaturia decreases Klotho expression through the activation of Wnt/β-catenin pathway.-Muñoz-Castañeda, J.

Various questions arise in the application of ICRP ''Standard Man'' values to Japanese. One of the questions is that ''Standard Man'' values of the thyroid are different from normal Japanese values. A systematic survey of past reports was carried out with a view to search for normal Japanese values of the thyroid. The subjects of search were weight, iodine content and iodine uptake rate (f sub(w)) of the thyroid. These are important factors in the estimation of the radiation dose of the thyroid caused by internal contamination of radioiodine, and are foreseen to have the difference between Japanese and ''Standard Man''. The result of study suggested that the weight of the thyroid of normal Japanese is about 19 g for adult male and about 17 g for adult female, and that the iodine content is 12-22 mg and iodine uptake rate (f sub(w)) is about 0.2.

Full Text Available Indonesian marriage states that marriage is physical and spiritual relationship between a man and a woman as husband and wife in order to create an eternal happy family based on the Almighty God. This definition reflects that the marriage in Indonesia must be between heterosexual couple. However, a question appears as to whether a man or a woman mentioned thereof is included a man and a woman who were, hermaphrodite, intersex, or nowadays known as person with Disorder of Sexual Development (DSD? The case of AH whereby his marriage is cancelled by the Supreme Court in 2014 for he is not considered as a man, is confirming that this question is important to value the capacity of a person to marry. This writing will apply normative research as well as literature research method upon the positive rules and regulations. The decisions of district courts upon the revision or change of gender and its legal basis will be analysed and be the topic of discussion. Comparison will be applied to compare the marriage requirements between Indonesian Law, Singapore Law and Hong Kong Law. The results of analyse and discussion will be the closure of the writing, as conclusions and advise, if any.

The effects of ionizing radiation on man

International Nuclear Information System (INIS)

Watson, G.M.

1975-08-01

This paper describes the major effects of ionizing radiation on man and the relationship between such effects and radiation dose, with the conclusion that standards of radiological safety must be based on the carcinogenetic and mutagenic properties of ionizing radiation. Man is exposed to radiation from natural sources and from man-made sources. Exposure from the latter should be regulated but, since there is little observational or experimental evidence for predicting the effects of the very small doses likely to be required for adequate standards of safety, it is necessary to infer them from what is seen at high doses. Because the formal relationship between dose and effect is not fully understood, simplifying assumptions are necessary to estimate the effects of low doses. Two such assumptions are conventionally used; that there is a linear relationship between dose and effect at all levels of dose, and that the rate at which a dose of radiation is given does not alter the magnitude of the effect. These assumptions are thought to be conservative, that is they will not lead to an underestimation of the effects of small radiation doses although they may give an over-estimate. (author)

Bermeo, Sandra; Al-Saedi, Ahmed; Kassem, Moustapha; Vidal, Christopher; Duque, Gustavo

2017-12-01

Mutations in MAN1, a protein of the nuclear envelope, cause bone phenotypes characterized by hyperostosis. The mechanism of this pro-osteogenic phenotype remains unknown. We increased and decreased MAN1 expression in mesenchymal stem cells (MSC) upon which standard osteogenic and adipogenic differentiation were performed. MAN1 knockdown increased osteogenesis and mineralization. In contrast, osteogenesis remained stable upon MAN1 overexpression. Regarding a mechanism, we found that low levels of MAN1 facilitated the nuclear accumulation of regulatory smads and smads-related complexes, with a concurrently high expression of nuclear β-Catenin. In addition, we found adipogenesis to be decreased in both conditions, although predominantly affected by MAN1 overexpression. Finally, lamin A, a protein of the nuclear envelope that regulates MSC differentiation, was unaffected by changes in MAN1. In conclusion, our studies demonstrated that lower levels of MAN1 in differentiating MSC are associated with higher osteogenesis and lower adipogenesis. High levels of MAN1 only affected adipogenesis. These effects could have an important role in the understanding of the role of the proteins of the nuclear envelope in bone formation. J. Cell.

Expression of the agmatine deiminase pathway in Enterococcus faecalis is activated by the AguR regulator and repressed by CcpA and PTS(Man systems.

Directory of Open Access Journals (Sweden)

Cristian Suárez

Full Text Available Although the agmatine deiminase system (AgDI has been investigated in Enterococcus faecalis, little information is available with respect to its gene regulation. In this study we demonstrate that the presence of exogenous agmatine induces the expression of agu genes in this bacterium. In contrast to the homologous and extensively characterized AgDI system of S. mutants, the aguBDAC operon in E. faecalis is not induced in response to low pH. In spite of this, agmatine catabolism in this bacterium contributes by neutralizing the external medium while enhancing bacterial growth. Our results indicate that carbon catabolic repression (CCR operates on the AgDI system via a mechanism that involves interaction of CcpA and P-Ser-HPr with a cre site found in an unusual position considering the aguB promoter (55 nt upstream the +1 position. In addition, we found that components of the mannose phosphotransferase (PTS(Man system also contributed to CCR in E. faecalis since a complete relief of the PTS-sugars repressive effect was observed only in a PTS(Man and CcpA double defective strain. Our gene context analysis revealed that aguR is present in oral and gastrointestinal microorganisms. Thus, regulation of the aguBDAC operon in E. faecalis seems to have evolved to obtain energy and resist low pH conditions in order to persist and colonize gastrointestinal niches.

In breast cancer cell lines, the Na(+)/H(+) exchanger regulator factor 1 (NHERF1) gene is regulated at the transcriptional level by estrogens, the protein expression levels correlate with the presence of estrogen receptors and the effect is blocked by anti-estrogens. However, there is limited information regarding the regulation of NHERF1 by estrogens in normal colon tissue. The NHERF1 protein has an important role in the maintenance of the intestine ultrastructure. NHERF1-deficient mice showed defects in the intestinal microvilli as well as molecular alterations in brush border membrane proteins. Here, we have studied the expression of NHERF1 in normal rat colon and uterus during the reproductive cycle of Wistar rats. We found that NHERF1 expression in rat colon during the estral cycle is modified by estrogen levels: higher expression of NHERF1 was observed during the proestrous and estrous stages and lower expression in diestrous 1 when estrogen levels decreased. In uterus, NHERF1 was expressed in the apical region of the luminal epithelium and glands in all stages of the estral cycle, and in both colon and uterus, the expression was independent of the proliferation status. Our results show that NHERF1 expression is regulated by estrogens in colon during the rat estral cycle.

Heavy metal pollution of man and environment - A historical perspective

International Nuclear Information System (INIS)

Jaworowski, Zbigniew

1989-01-01

'Normal' levels of heavy metals are disturbingly close to toxic levels. This may be a man-made or natural phenomenon. The man-made exposure to heavy metals started thousands of years ago. In some European populations in the past the lead level was orders of magnitude higher than now, where it is comparable with the prehistoric level. The former high contamination of human populations was due to intake of metals from immediate sources (utensils, drugs, etc) not to their dispersion in the environment. A dramatic decrease of lead level in man occurred recently, when the majority of the immediate sources disappeared, but when at the local (but not at the global) scale the environmental level of metals increased. The current flow of metals into the global atmosphere, similar to the pre-industrial flow, is still dominated by natural processes, such as biological methylization of metals. This leads to an enrichment of the airborne particles in metals up to several orders of magnitude above the crustal abundances. It is not the magnitude of emissions of metals into the global atmosphere that marks a new role of man in the biosphere, but the mass of anthropogenic mobilization of raw materials now reaching the geological dimensions.

Although there is a long history of consanguineous marriage in China, information on its prevalence is very limited. The Man (Qing) dynasty ruled China for over 250 years, but no consanguinity studies have been reported on this important population. The objective of the present investigation was to determine the present-day level of consanguineous marriage in the Man community, and to compare the data with existing consanguinity information on other Chinese populations. The study was conducted in a group of 11 rural Man communities in the north-eastern Chinese province of Liaoning. Household-based interviews were conducted by local staff on 513 couples, 418 of whom were Man with another 95 Man-Han inter-ethnic marriages. Basic pedigrees were constructed to determine the biological relationship between each set of spouses. Thirty of the 418 couples were in a consanguineous union, with a mean coefficient of inbreeding alpha = 0.0012. The small population sizes of the study may have contributed to the spatial variation in the patterns of inbreeding. Across generations there was a reduction in consanguineous marriages and an increase in inter-ethnic unions, which paralleled changes in civil marriage regulations.

Epigenetic mechanisms are important regulators of cell type–specific genes, including miRNAs. In order to identify cell type-specific miRNAs regulated by epigenetic mechanisms, we undertook a global analysis of miRNA expression and epigenetic states in three isogenic pairs of human mammary epithelial cells (HMEC) and human mammary fibroblasts (HMF), which represent two differentiated cell types typically present within a given organ, each with a distinct phenotype and a distinct epigenotype. While miRNA expression and epigenetic states showed strong interindividual concordance within a given cell type, almost 10% of the expressed miRNA showed a cell type–specific pattern of expression that was linked to the epigenetic state of their promoter. The tissue-specific miRNA genes were epigenetically repressed in nonexpressing cells by DNA methylation (38%) and H3K27me3 (58%), with only a small set of miRNAs (21%) showing a dual epigenetic repression where both DNA methylation and H3K27me3 were present at their promoters, such as MIR10A and MIR10B. Individual miRNA clusters of closely related miRNA gene families can each display cell type–specific repression by the same or complementary epigenetic mechanisms, such as the MIR200 family, and MIR205, where fibroblasts repress MIR200C/141 by DNA methylation, MIR200A/200B/429 by H3K27me3, and MIR205 by both DNA methylation and H3K27me3. Since deregulation of many of the epigenetically regulated miRNAs that we identified have been linked to disease processes such as cancer, it is predicted that compromise of the epigenetic control mechanisms is important for this process. Overall, these results highlight the importance of epigenetic regulation in the control of normal cell type–specific miRNA expression.

The timely and precise duplication of cellular DNA is essential for maintaining genome integrity and is thus tightly-regulated. During mitosis and G1, the Origin Recognition Complex (ORC) binds to future replication origins, coordinating with multiple factors to load the minichromosome maintenance (MCM) complex onto future replication origins as part of the pre-replication complex (pre-RC). The pre-RC machinery, in turn, remains inactive until the subsequent S phase when it is required for replication fork formation, thereby initiating DNA replication. Multiple myeloma SET domain-containing protein (MMSET, a.k.a. WHSC1, NSD2) is a histone methyltransferase that is frequently overexpressed in aggressive cancers and is essential for normal human development. Several studies have suggested a role for MMSET in cell-cycle regulation; however, whether MMSET is itself regulated during cell-cycle progression has not been examined. In this study, we report that MMSET is degraded during S phase in a cullin-ring ligase 4-Cdt2 (CRL4(Cdt2)) and proteasome-dependent manner. Notably, we also report defects in DNA replication and a decreased association of pre-RC factors with chromatin in MMSET-depleted cells. Taken together, our results suggest a dynamic regulation of MMSET levels throughout the cell cycle, and further characterize the role of MMSET in DNA replication and cell-cycle progression.

From the rights of man to the human rights: Man - nation - humanity

Directory of Open Access Journals (Sweden)

Zaharijević Adriana

2008-01-01

Full Text Available The insistence on the fact that human rights and the rights of man (codified in The Universal Declaration of Human Rights and Declaration of the Rights of Man and of the Citizen, respectively are not one and the same, which could be deduced from the notion of man common to both terms, is the key thesis of this text. By developing this motive, I try to determine the following: that the notion of man, by definition inclusive and abstractly non-discriminative term, is in fact established on tacit exclusions in the time of its inception (Enlightenment revolutinary era, and it was only upon these exclusions that the term man could have signified "the free and equal". Although the parallel or simultaneous evolution and implementation of the rights of man and national rights might seem contradictory, I seek to demonstrate that this paradox is only ostensible, arguing that the notion of man is itself limited and exclusionary, and is therefore compatible with the exclusivity which is the conditio sine qua non of nation. The consequences of nationalism - World Wars, primarily - proved that the conception of liberty and equality, based on the conception of fraternity of men (white European males, and of partial democracy pretending to be universal, cannot be maintained any further. Codification of universal human rights represents a reaction to this internal discrepancy inasmuch as it is a reaction to the destructiveness of all kinds of nationalisms. The notion of life, developed in this text, corresponds to the fundamental requirement for the right to life (as the first and the most basic of all human rights, which no longer belongs to "man", but to everyone.

We present the case of an 18-year-old man, previously healthy, who presented with acute quadriplegia and respiratory failure. Physical examination was compatible with a high cervical anterior spinal cord lesion. We plan to evaluate the cause of such a neurological presentation in a healthy young man. American University Medical Center, Beirut, Lebanon. The patient underwent routine blood hematological and chemistry work-up, hypercoagulable profile studies, genetic profile for thrombophelias, radiographic studies of the brain and cervical cord, cerebrospinal analysis and extensive electrophyisological studies. Magnetic resonance imaging and magnetic resonance angiogram of the brain, carotid and intracranial vessels were normal. Cerebral angiography was normal. Magnetic resonance imaging of the cervical cord revealed lesion of the anterior segment of the cervical cord between C2 and C5 levels. Hypercoagulable profile studies were normal. Electrophysiological studies confirmed an isolated lesion of the descending cortico-spinal tracts. DNA analysis revealed the presence of a G20210A mutation-causing hyperprothrombinemia. We conclude that a G20210A mutation causing-hyperprothrombinemia can cause anterior spinal artery thrombosis and anterior spinal cord infarction with the resultant neurological deficits in otherwise healthy patients.

Lahlou-Kassi, A.; Boukhliq, R.

1988-01-01

The effect of photoperiod on sexual activity was investigated in Sardi and D'man ewes. Twenty ewes from each breed were subjected to an experimental photoperiod corresponding to latitude 56 deg. N. Control ewes (12 per breed) were maintained under natural photoperiod (32 deg. N). Behavioural oestrus and ovarian activity were monitored using penis deviated rams and plasma progesterone levels. Preliminary results from this study show that an increase in amplitude of photoperiod variations causes a decrease in the expression of oestrous behaviour in D'man ewes during the period of decreasing daylight. Ovarian activity remained unchanged. Sardi ewes were not markedly affected by change in photoperiod. (author). 13 refs, 3 figs, 1 tab

The 'poor man's laryngogram'

1991-01-01

This paper is reassessment of an old method improved by well-directed application of well-known maneuvers of laryngo-pharyngeal function. Although not as visually attractive as a dedicated laryngogram (now hardly ever requested), it does render similarly reliable diagnostic information, which, supported, as occasionally necessary, by conventional tomography, can even surpass that given by the older technique. Its main advantage lies in providing cheap, quick, noninvasive studies with minimal descomfort for the patient. Should further investigation be necessary, for analysis of deep extension, modern cross-sectional imaging methods (especially MR) far surpass even dedicated laryngography in diagnostic value and can be based adequately on 'poor mans's laryngography'. Ways in which this method may be optimised, especially those involving laryngopharyngeal function, are briefly presented - with emphasis on relevant practical aspects - as are normal and abnormal findings.

The 2-nitroimidazole benznidazole (BENZO) has previously been shown to be an effective potentiator of the cytotoxicity of CCNU in mice, at levels which are achievable in man. In this study BENZO has been given to 46 patients in oral doses of 4 mg/kg to 30 mg/kg, and drug concentrations measured in plasma, urine, tumor and normal brain by HPLC. Approximately 60% of the drug was bound to plasma proteins and 6% excreted unchanged in urine. Mean tumor/plasma ratios of 88% for 11 gliomas and 72% for 6 superficially accessible non-brain tumors were obtained while that for normal brain was 69%. Doses of more than 17 mg/kg BENZO produce changes in the plasma pharmacokinetics of CCNU, increasing the half life of active hydroxylated metabolites. In addition, CCNU parent compound is present. This is not seen when CCNU is given alone. Such changes may result in improved response rates as it is possible to achieve in man, plasma and tumor levels of BENZO, which in the mouse model produce effective enhancement of the response to CCNU

In a previous study, we reported changes in the use of two different emotion regulation strategies at an annual alternative cultural event, Burning Man (McRae, Heller, John, & Gross, 2011. In this sociocultural context, as compared to home, participants reported less use of expressive suppression (a strategy generally associated with maladaptive outcomes, and greater use of cognitive reappraisal (a strategy associated with adaptive outcomes. What remained unclear was whether these changes in self-reported emotion regulation strategy use were characterized by changes in the regulation of positive emotion, negative emotion, or both. We addressed this issue in the current study by asking Burning Man participants separate questions about positive and negative emotion. Using multiple datasets, we not only replicated our previous findings, but also found that the decreased use of suppression is primarily driven by reports of decreased suppression of positive emotion at Burning Man. By contrast, the reported increased use of reappraisal is not characterized by differential reappraisal of positive and negative emotion at Burning Man. Moreover, we observed novel individual differences in the magnitude of these effects. The contextual changes in self-reported suppression that we report are strongest for men and younger participants. For those who had previously attended Burning Man, we observed lower levels of self-reported suppression in both sociocultural contexts: Burning Man and home. These findings have implications for understanding the ways in which certain sociocultural contexts may decrease suppression, and possibly minimize its associated maladaptive effects.

A 31-year-old man presented at the endocrinology out-patient clinic for the initiation of sex-change treatment. His manifestly transsexual male-to-female appearance was confirmed by a psychiatric-sexological expert report. The patient had been living as a woman for one year. Physical examination showed normal male physique with typical secondary hair growth and normal male genitals. The serum testosterone level was at the upper limits of normal, that for oestrogen at the lower limit. Bone densitometry showed bone density at the upper limit of normal. Other laboratory tests were unremarkable. During 30 months on cyproterone, 100 mg daily, bone mass fell at the rate of 5% per year. Bone biopsy revealed high turnover osteoporosis. Bone mass rose by 4% per year after the additional oral intake of oestradiol valerate, 2 mg daily. Osteoblastic cells, isolated from part of the biopsy tissue, with the patient's consent, was found to be stimulated by oestradiol in vitro. The described bone mass changes indicate the important role played by sex hormones in the maintenance of bone mass acquired during adolescence. The findings confirm that in males not only testosterone but also oestrogens has an anabolic effect on bone.

Cystic fibrosis transmembrane conductance regulator (CFTR) has been demonstrated to be expressed in mature spermatozoa and correlated with sperm quality. Sperm CFTR expression in fertile men is higher than that in infertile men suffering from teratospermia, asthenoteratospermia, asthenospermia and oligospermia, but it is unknown whether CFTR is correlated with sperm parameters when sperm parameters are normal. In this study, 282 healthy and fertile men with normal semen parameters were classified into three age groups, group (I): age group of 20-29 years (98 cases, 27.1 ± 6.2), group (II): age group of 30-39 years (142 cases, 33.7 ± 2.6) and group (III): age group of more than or equal to 40 years (42 cases, 44.1 ± 4.6). Sperm concentration, total count and progressive motility were analysed by computer-assisted sperm analysis. Sperm morphology was analysed by modified Papanicolaou staining. Sperm CFTR expression was conducted by indirect immunofluorescence staining. There was a significant positive correlation (P sperm progressive motility (r = 0.221) and normal morphology (r = 0.202), but there were no correlations between sperm CFTR expression and semen volume, sperm concentration, sperm total count as well as male age (P > 0.05). Our findings show that CFTR expression is associated with sperm progressive motility and normal morphology in healthy and fertile men with normal sperm parameters, but not associated with the number of spermatozoa and male age. © 2013 Blackwell Verlag GmbH.

Reference Japanese man

To make real and accurate dose assessment method so far, it is necessitated to provide ''Reference Japanese Man'' based on anotomical, physiological and biochemical data of Japanese people instead of the Reference Man presented in ICRP Publications 23 and 30. This review describes present status of researched for the purpose of establishing of Reference Japanese Man. The Reference Japanese Man is defined as a male or female adult who lives in Japan with a Japanese life-style and food custom. His stature and body weight, and the other data was decided as mean values of male or female people of Japan. As for food custom, Japanese people take significantly smaller amount of meat and milk products than Western people, while larger intake amount of cereals and marine products such as fish or seaweeds. Weight of organs is a principal factor for internal dose assessment and mean values for living Japanese adult has been investigated and the value employable for dose assessment for organs and tissues are shown. To employ these values of Reference Japanese Man, it should be taken into account of age. Metabolic parameters should also be considered. Iodine metabolism in Japanese is quite different from that of Western people. The above-mentioned data are now tentatively employing in modification of table of MIRD method and others. (Takagi, S.)

Two-phase deep-lung clearance in man

Bohning, D.E.; Cohn, S.H.; Lee, H.D.; Atkins, H.L.

1980-01-01

For toxicological as well as physiological considerations, it is important to determine whether the long-term clearance of particles from the lungs of man takes place in more than one temporal subphase. Although long-term retention can be characterized with a single exponential, the existence of two distinct components would significantly alter estimates of overall residence times and hence potential effects of inhaled particulates. Physiological interpretations of the mechanisms of long-term particle clearance depend on the identification and quantification of such temporal subphases. A highly sensitive whole-body counter was used to measure the long-term retention of inhaled particles in man. After inhalation of 85 Sr, lung retention was monitored in eight volunteers for periods ranging from 197 to 399 days. Their pulmonary-function values fell within normal limits, and they reported no symptoms of lung disease. Four of the individuals had never smoked, and four had not smoked for a minimum of 5 years. Single exponential representation half-times for the long-term retention were comparable between the two groups and were combined to give a mean half-time of 197 +- 32 days

Phosphorylation of intracellular proteins related to the multihormonal regulation of prolactin: comparison of normal anterior pituitary cells in culture with the tumor-derived GH cell lines

International Nuclear Information System (INIS)

Beretta, L.; Boutterin, M.C.; Sobel, A.

1988-01-01

We have previously identified a group of cytoplasmic phosphoproteins (proteins 1-11) whose phosphorylation could be related, on a pharmacological basis, to the multihormonal regulation of PRL synthesis and release in the anterior pituitary tumor-derived GH cell lines. Phosphoproteins with identical migration properties on two-dimensional electrophoresis gels were also detectable in normal rat anterior pituitary cells in culture. We designed appropriate culture and [ 32 P] phosphate-labeling conditions allowing to analyze the regulation of the phosphorylation of these proteins in normal pituitary cells. TRH, 12-O-tetradecanoylphorbol-13-acetate, and vasoactive intestinal peptide induced the same qualitative changes in phosphorylation of proteins 1-11 in normal as in GH cells. Quantitative differences observed are most likely due to the heterogeneity of primary pituitary cultures. Phosphorylation changes affecting proteins 14-16, not previously detected in GH cells, were also observed with normal anterior pituitary cells. GH cell lines have lost the sensitivity of pituitary lactotrophs for dopamine, an important physiological inhibitor of PRL synthesis and release. In normal anterior pituitary cells in culture, dopamine inhibited also the TRH-stimulated phosphorylation of proteins 1-10, thus strengthening the correlation between phosphorylation of these proteins and multihormonal regulation of pituitary cell functions. Our results indicate: 1) that the same phosphoproteins as in GH cells are related to the multihormonal regulation of nontumoral, normal anterior pituitary cells in culture; 2) that dopamine acts by interfering with the phosphorylation of these proteins

Estimated dose to man from uranium milling via the terrestrial food-chain pathway

Energy Technology Data Exchange (ETDEWEB)

Rayno, D.R.

1982-01-01

One of the major pathways of radiological exposure to man from uranium milling operations is through the terrestrial food chain. Studies by various investigators have shown the extent of uptake and distribution of U-238, U-234, Th-230, Ra-226, Pb-210, and Po-210 in plants and animals. These long-lived natural radioisotopes, all nuclides of the uranium decay series, are found in concentrated amounts in uranium mill tailings. Data from these investigations are used to estimate the dose to man from consumption of beef and milk contaminated by the tailings. This dose estimate from this technologically enhanced source is compared with that from average normal dietary intake of these radionuclides from natural sources.

Regulation of HGF and c-MET Interaction in Normal Ovary and Ovarian Cancer.

Science.gov (United States)

Kwon, Youngjoo; Godwin, Andrew K

2017-04-01

Binding of hepatocyte growth factor (HGF) to the c-MET receptor has mitogenic, motogenic, and morphogenic effects on cells. The versatile biological effects of HGF and c-MET interactions make them important contributors to the development of malignant tumors. We and others have demonstrated a therapeutic value in targeting the interaction of c-MET and HGF in epithelial ovarian cancer (EOC). However, both HGF and c-MET are expressed in the normal ovary as well. Therefore, it is important to understand the differences in mechanisms that control HGF signaling activation and its functional role in the normal ovary and EOC. In the normal ovary, HGF signaling may be under hormonal regulation. During ovulation, HGF-converting proteases are secreted and the subsequent activation of HGF signaling enhances the proliferation of ovarian surface epithelium in order to replenish the area damaged due to expulsion of the ovum. In contrast, EOC cells that exhibit epithelial characteristics constitutively express both c-MET and HGF-converting proteases such as urokinase-type plasminogen activator. In EOC, mechanisms to control the activation of HGF signaling are absent since HGF is provided locally from the tissue microenvironment as well as remotely throughout the body. Potential incessant HGF signaling in EOC may lead to an increase in proliferation, invasion through the stroma, and migration to other tissues of cancer cells. Therefore, targeting the interaction of c-MET and HGF would be beneficial in treating EOC.

Serum cholinesterases are differentially regulated in normal and dystrophin-deficient mutant mice

Directory of Open Access Journals (Sweden)

Andrea R. Durrant

2012-06-01

Full Text Available The cholinesterases, acetylcholinesterase and butyrylcholinesterase (pseudocholinesterase, are abundant in the nervous system and in other tissues. The role of acetylcholinesterase in terminating transmitter action in the peripheral and central nervous system is well understood. However, both knowledge of the function(s of the cholinesterases in serum, and of their metabolic and endocrine regulation under normal and pathological conditions, is limited. This study investigates acetylcholinesterase and butyrylcholinesterase in sera of dystrophin-deficient mdx mutant mice, an animal model for the human Duchenne muscular dystrophy and in control healthy mice. The data show systematic and differential variations in the concentrations of both enzymes in the sera, and specific changes dictated by alteration of hormonal balance in both healthy and dystrophic mice. While acetylcholinesterase in mdx-sera is elevated, butyrylcholinesterase is markedly diminished, resulting in an overall cholinesterase decrease compared to sera of healthy controls. The androgen testosterone (T is a negative modulator of butyrylcholinesterase, but not of acetylcholinesterase, in male mouse sera. T-removal elevated both butyrylcholinesterase activity and the butyrylcholinesterase/acetylcholinesterase ratio in mdx male sera to values resembling those in healthy control male mice. Mechanisms of regulation of the circulating cholinesterases and their impairment in the dystrophic mice are suggested, and clinical implications for diagnosis and treatment are considered.

Development of the Japanese reference man model for age-specific phantoms

International Nuclear Information System (INIS)

Kawamura, H.

2012-01-01

Recent interest in improving methods for calculating radiation doses to atomic bomb survivors necessitates reinforcing the data on masses of organs of the Japanese population in 1945, including those that are not calculated by DS02, as well as increasing the number of phantoms for different ages. Reference is made to published data on the masses of organs in normal Japanese subjects of 0-90 y of age with more than 5000 samples during 1970-80, as well as the weight and size of the total body. The first Japanese Reference Man model, primarily based on these data and following the ICRP Reference Man concept, is briefly explained. It provides a set of reference values for males and females of six age groups, i.e. 3 months, 1, 5, 10, 15 and 20-50 y. To consider the organ masses of the Japanese population in 1945, the data during the period 1970-80 are compared with the literature data of normal Japanese reported in 1952. Differences between the two sets of organ data in adults are discussed in relation to changes in the national status of nutrition. Additional organ masses of current interest for the Japanese population in 1945 are preliminarily considered. (author)

Model for assessing alpha doses for a Reference Japanese Man

Kawamura, Hisao

1993-01-01

In view of the development of the nuclear fuel cycle in this country, it is urgently important to establish dose assessment models and related human and environmental parameters for long-lived radionuclides. In the current program, intake and body content of actinides (Pu, Th, U) and related alpha-emitting nuclides (Ra and daughters) have been studied as well as physiological aspects of Reference Japanese Man as the basic model of man for dosimetry. The ultimate object is to examine applicability of the existing models particularly recommended by the ICRP for workers to members of the public. The result of an interlaboratory intercomparison of 239 Pu + 240 Pu determination including our result was published. Alpha-spectrometric determinations of 226 Ra in bone yielded repesentative bone concentration level in Tokyo and Ra-Ca O.R. (bone-diet) which appear consistent with the literature value for Sapporo and Kyoto by Ohno using a Rn emanation method. Specific effective energies for alpha radiation from 226 Ra and daughters were calculated using the ICRP dosimetric model for bone incorporating masses of source and target organs of Reference Japanese Man. Reference Japanese data including the adult, adolescent, child and infant of both sexes was extensively and intensively studied by Tanaka as part of the activities of the ICRP Task Group on Reference Man Revision. Normal data for the physical measurements, mass and dimension of internal organs and body surfaces and some of the body composition were analysed viewing the nutritional data in the Japanese population. Some of the above works are to be continued. (author)

A novel mean-centering method for normalizing microRNA expression from high-throughput RT-qPCR data

Directory of Open Access Journals (Sweden)

Wylie Dennis

2011-12-01

Full Text Available Abstract Background Normalization is critical for accurate gene expression analysis. A significant challenge in the quantitation of gene expression from biofluids samples is the inability to quantify RNA concentration prior to analysis, underscoring the need for robust normalization tools for this sample type. In this investigation, we evaluated various methods of normalization to determine the optimal approach for quantifying microRNA (miRNA expression from biofluids and tissue samples when using the TaqMan® Megaplex™ high-throughput RT-qPCR platform with low RNA inputs. Findings We compared seven normalization methods in the analysis of variation of miRNA expression from biofluid and tissue samples. We developed a novel variant of the common mean-centering normalization strategy, herein referred to as mean-centering restricted (MCR normalization, which is adapted to the TaqMan Megaplex RT-qPCR platform, but is likely applicable to other high-throughput RT-qPCR-based platforms. Our results indicate that MCR normalization performs comparable to or better than both standard mean-centering and other normalization methods. We also propose an extension of this method to be used when migrating biomarker signatures from Megaplex to singleplex RT-qPCR platforms, based on the identification of a small number of normalizer miRNAs that closely track the mean of expressed miRNAs. Conclusions We developed the MCR method for normalizing miRNA expression from biofluids samples when using the TaqMan Megaplex RT-qPCR platform. Our results suggest that normalization based on the mean of all fully observed (fully detected miRNAs minimizes technical variance in normalized expression values, and that a small number of normalizer miRNAs can be selected when migrating from Megaplex to singleplex assays. In our study, we find that normalization methods that focus on a restricted set of miRNAs tend to perform better than methods that focus on all miRNAs, including

Coordinated Regulation of the EIIMan and fruRKI Operons of Streptococcus mutans by Global and Fructose-Specific Pathways.

2017-11-01

The glucose/mannose-phosphotransferase system (PTS) permease EII Man encoded by manLMN in the dental caries pathogen Streptococcus mutans has a dominant influence on sugar-specific, CcpA-independent catabolite repression (CR). Mutations in manL affect energy metabolism and virulence-associated traits, including biofilm formation, acid tolerance, and competence. Using promoter::reporter fusions, expression of the manLMN and the fruRKI operons, encoding a transcriptional regulator, a fructose-1-phosphate kinase and a fructose-PTS permease EII Fru , respectively, was monitored in response to carbohydrate source and in mutants lacking CcpA, FruR, and components of EII Man Expression of genes for EII Man and EII Fru was directly regulated by CcpA and CR, as evinced by in vivo and in vitro methods. Unexpectedly, not only was the fruRKI operon negatively regulated by FruR, but also so was manLMN Carbohydrate transport by EII Man had a negative influence on expression of manLMN but not fruRKI In agreement with the proposed role of FruR in regulating these PTS operons, loss of fruR or fruK substantially altered growth on a number of carbohydrates, including fructose. RNA deep sequencing revealed profound changes in gene regulation caused by deletion of fruK or fruR Collectively, these findings demonstrate intimate interconnection of the regulation of two major PTS permeases in S. mutans and reveal novel and important contributions of fructose metabolism to global regulation of gene expression. IMPORTANCE The ability of Streptococcus mutans and other streptococcal pathogens to survive and cause human diseases is directly dependent upon their capacity to metabolize a variety of carbohydrates, including glucose and fructose. Our research reveals that metabolism of fructose has broad influences on the regulation of utilization of glucose and other sugars, and mutants with changes in certain genes involved in fructose metabolism display profoundly different abilities to grow and

The rights of man and animal experimentation.

Science.gov (United States)

Martin, J

1990-01-01

Since emotions give contradictory signals about animal experimentation in medical science, man's relationship to animals must be based upon reason. Thomas Aquinas argues that man is essentially different from animals because man's intellectual processes show evidence of an abstract mechanism not possessed by animals. Man's rights arise in association with this essential difference. The consequence is that only man possesses true rights by Aquinas's definition; animals have them only by analogy. However, cruelty to animals is illicit and they should be protected, principally not because they have rights, but because he who is cruel to animals is more likely to be cruel to his fellowman. If there is a need for animal experimentation in science for the good of man, this approach gives philosophical justification for experimentation, since man's well-being must come before that of animals because of his unique possession of rights. However, those experiments should be carried out in the kindest way possible, to promote kindness towards man. To see man as solely part of a biological continuum in competition for rights with those beings close to him biologically, detracts from man's dignity. PMID:2135948

1998-01-01

Studies on the physical, anatomical, and partial metabolic as well as physiological characteristics on Reference Japanese Man were undertaken to establish reference values for use in internal dose assessment and to assign annual limits on intakes of radionuclides for Japanese workers and members of the general public. Secular trends in, and/or probable influences of nutritional conditions on the organ mass were examined by comparing the present results with the other normal Japanese data. The average height of male and female adults (20-50 y) were 168 and 155 cm, respectively. The body weights for males and females, 20-50 y, were - 64 and 52 kg. The data on the weight and size of twelve organs in normal males and eleven in normal females were obtained from autopsy, 12 to 24 h after sudden death. The per caput intake of foodstuffs and principal nutrients were taken from the annual report of the National nutrition Survey for households in the urban and rural areas in all districts of Japan. Determination of elemental intake was made by collecting, one full day of meals for adult males from 31 prefectures in practically all districts of Japan. Pulmonary function parameters studied include total lung capacity, vital capacity, minute volume and 8 h working volume at various levels of exertion - resting, light and heavy activity. The subjects were healthy, normal Japanese males and females. Water balance data were obtained for 9 males and 6 females in Tokyo, under conditions of controlled energy and salt intake. The lengths of the study period were 6 and 10 days, respectively. Daily intakes of energy and salt were determined for the male student athletes for whom an indoor physical training was assigned.

2001-01-01

First, this paper gives a short general review on important safety issues in the field of man-machine interaction as expressed by important nuclear safety organisations. Then follows a summary discussion on what constitutes a modern Man-Machine Interface (MMI) and what is normally meant with accident management and accident management strategies. Furthermore, the paper focuses on three major issues in the context of accident management. First, the need for reliable information in accidents and how this can be obtained by additional computer technology. Second, the use of procedures is discussed, and basic MMI aspects of computer support for procedure presentation are identified followed by a presentation of a new approach on how to computerise procedures. Third, typical information needs for characteristic end-users in accidents, such as the control room operators, technical support staff and plant emergency teams, is discussed. Some ideas on how to apply virtual reality technology in accident management is also presented

The books are Sur l'homme et le développement de ses facultés and Du systeme social et des lois qui le régissent. Both reveal that Quetelet's ideas are permeated by explanatory strategies drawn from physics and astronomy, and also by discursive strategies drawn from theology and religion. The stability of the mean as opposed to the dispersion of individual characteristics and events provided the basis for the use of statistics in social sciences and medicine.

Biomedical support of man in space

Pendergast, D. R.; Olszowka, A. J.; Rokitka, M. A.; Farhi, L. E.

In its broadest sense, biomedical support of man in space must not be limited to assisting spacecraft crew during the mission; such support should also ensure that flight personnel be able to perform properly during landing and after leaving the craft. Man has developed mechanisms that allow him to cope with specific stresses in his normal habitat; there is indisputable evidence that, in some cases, the space environment, by relieving these stresses, has also allowed the adaptive mechanisms to lapse, causing serious problems after re-entry. Inflight biomedical support must therefore include means to simulate some of the normal stresses of the Earth environment. In the area of cardiovascular performance, we have come to rely heavily on complex feedback mechanisms to cope with two stresses, often combined: postural changes, which alter the body axis along which gravitational acceleration acts, and physical exercise, which increases the total load on the system. Unless the appropriate responses are reinforced continuously during flight, crew members may be incapacitated upon return. The first step in the support process must be a study of the way in which changes in g, even of short duration, affect these responses. In particular we should learn more about effects of g on the "on" and "off" dynamics, using a variety of approaches: increased acceleration on one hand at recumbency, immersion, lower body positive pressure, and other means of simulating some of the effects of low g, on the other. Once we understand this, we will have to determine the minimal exposure dose required to maintain the response mechanisms. Finally, we shall have to design stresses that simulate Earth environment and can be imposed in the space vehicle. Some of the information is already at hand; we know that several aspects of the response to exercise are affected by posture. Results from a current series of studies on the kinetics of tilt and on the dynamics of readjustment to exercise in

Jian Zhou

Full Text Available OBJECTIVE: Although the association between alanine aminotransferase (ALT levels and risk of type 2 diabetes is well-studied, the effects of slightly increased ALT levels within the normal range on the temporal normal glucose profile remains poorly understood. METHODS: A total of 322 Chinese subjects without impaired glucose tolerance or previous diagnoses of diabetes were recruited for study from 10 hospitals in urban areas across China. All subjects wore a continuous glucose monitoring (CGM system for three consecutive days. The diurnal (06∶00-20∶00 and nocturnal (20∶00-06∶00 mean blood glucose (MBG levels were calculated. Subjects were stratified by ALT quartile level and correlation analyses were performed. RESULTS: The median ALT level was 17 IU/L, and subjects with ALT ≥17 IU/L had higher nocturnal MBG level than those with ALT 0.05. Multivariate stepwise regression analysis of elevated nocturnal MBG identified increased HOMA-IR, elevated ALT levels, and decreased homeostatic model assessment of ß-cell function as independent factors (all, P<0.05. CONCLUSIONS: Mildly elevated ALT levels, within the normal range, are associated with unfavorable nocturnal glucose profiles in Chinese subjects with normal glucose regulation.

Due to the improvement of production technology and the adjustment of energy structure, as well as the town-ownership and private-ownership coal mines (TPCM) were closed or merged by national policy, the number of underground miner has changed comparing with 2004 in China, so collective dose and normalization collective dose in different type of coal mine should be changed at the same time. In this paper, according to radiation exposure by different ventilation condition and the annual output, the coal mines in China are divided into three types, which are named as national key coal mines (NKCM), station-owned local coal mines (SLCM) and TPCM. The number of underground coal miner, collective dose and normalization collective dose are estimated at present base on surveying annual output and production efficiency of raw coal in 2005-2014. The typical total value of the underground coal miners recommended in China is 5.1 million in 2005-2009, and in which there are respectively included 1 million, 0.9 million and 3.2 million for NKCM, SLCM and TPCM. There are total of 4.7 million underground coal miner in 2010-2014, and the respectively number for NKCM, SLCM and TPCM are 1.4 million, 1.2 million and 2.1 million. The collective dose in 2005-2009 is 11 335 man.Sv.y"-"1, and in which there are respectively included 280, 495 and 10 560 man.Sv.y"-"1 for NKCM, SLCM and TPCM. As far as 2010-2014, there are total of 7982 man.Sv.y"-"1, and 392, 660 and 6930 man.Sv.y"-"1 for each type of coal mines. Therefore, the main contributor of collective dose is from TPCM. The normalization collective dose in 2005-2009 is 0.0025, 0.015 and 0.117 man.Sv per 10 kt for NKCM, SLCM and TPCM, respectively. As far as 2010-2014, there are 0.0018, 0.010 and 0.107 man.Sv per 10 kt for each type of coal mines. The trend of normalization collective dose is decreased year by year. (authors)

Glycoprotein biosynthesis by human normal platelets

Rodriguez, P.; Bello, O.; Apitz-Castro, R.

1987-01-01

Incorporation of radioactive Man, Gal, Fuc, Glc-N, and NANA into washed human normal platelets and endogenous glycoproteins has been found. Both parameters were time dependent. Analysis of hydrolyzed labeled glycoproteins by paper chromatography revealed that the radioactive monosaccharide incubated with the platelets had not been converted into other sugars. Acid hydrolysis demonstrates the presence of a glycosidic linkage. All the effort directed to the demonstration of the existence of a lipid-sugar intermediate in intact human platelets yielded negative results for Man and Glc-N used as precursors. The incorporation of these sugars into glycoproteins is insensitive to bacitracin, suggesting no involvement of lipid-linked saccharides in the synthesis of glycoproteins in human blood platelets. The absence of inhibition of the glycosylation process in the presence of cycloheximide suggests that the sugars are added to proteins present in the intact platelets. These results support the contention that glycoprotein biosynthesis in human blood platelets observed under our experimental conditions is effected through direct sugar nucleotide glycosylation

Hypoxic regulation of cytoglobin and neuroglobin expression in human normal and tumor tissues

Directory of Open Access Journals (Sweden)

Emara Marwan

2010-09-01

Full Text Available Abstract Background Cytoglobin (Cygb and neuroglobin (Ngb are recently identified globin molecules that are expressed in vertebrate tissues. Upregulation of Cygb and Ngb under hypoxic and/or ischemic conditions in vitro and in vivo increases cell survival, suggesting possible protective roles through prevention of oxidative damage. We have previously shown that Ngb is expressed in human glioblastoma multiforme (GBM cell lines, and that expression of its transcript and protein can be significantly increased after exposure to physiologically relevant levels of hypoxia. In this study, we extended this work to determine whether Cygb is also expressed in GBM cells, and whether its expression is enhanced under hypoxic conditions. We also compared Cygb and Ngb expression in human primary tumor specimens, including brain tumors, as well as in human normal tissues. Immunoreactivity of carbonic anhydrase IX (CA IX, a hypoxia-inducible metalloenzyme that catalyzes the hydration of CO2 to bicarbonate, was used as an endogenous marker of hypoxia. Results Cygb transcript and protein were expressed in human GBM cells, and this expression was significantly increased in most cells following 48 h incubation under hypoxia. We also showed that Cygb and Ngb are expressed in both normal tissues and human primary cancers, including GBM. Among normal tissues, Cygb and Ngb expression was restricted to distinct cell types and was especially prominent in ductal cells. Additionally, certain normal organs (e.g. stomach fundus, small bowel showed distinct regional co-localization of Ngb, Cygb and CA IX. In most tumors, Ngb immunoreactivity was significantly greater than that of Cygb. In keeping with previous in vitro results, tumor regions that were positively stained for CA IX were also positive for Ngb and Cygb, suggesting that hypoxic upregulation of Ngb and Cygb also occurs in vivo. Conclusions Our finding of hypoxic up-regulation of Cygb/Ngb in GBM cell lines and human

Future space travellers and settlers will be exposed to a variety of electromagnetic fields (EMFs). Extrinsic sources will include solar and stellar fluxes, planetary fluxes, and supernovae. Intrinsic sources may include fusion and ion engines, EMFs from electrical equipment, radar, lighting, superconduction energy storage systems, magnetic bearings on gyroscopic control and orientation systems, and magnetic rail microprobe launch systems. Communication sources may include radio and microwave frequencies, and laser generating systems. Magnetic fields may also be used for deflection of radiation. There is also a loss of the normal Geomagnetic field (GMF) which includes static, alternating, and time-varying components. This paper reviews exposure limits and the biological effects of EMFs, and evidence for an electromagnetic sense organ and a relationship between man and the Geomagnetic field.

Full Text Available Introduction. Tuberculous (TB synovitis is a rare, treatable, potentially lethal form of extrapulmonary TB resulting from massive lymphohematogenous dissemination of Mycobacterium tuberculosis (M. tuberculosis. We presented a case of TB synovitis of the knee in a Caucasian HIV negative man from Romania, a high TB incidence country. Case report. A 65-year old man presented with cough, high fever, mild wheezing, and swelling of the left knee. Chest radiography was normal. Sputum smears were Acid Fast Bacilli negative and Löwenstein-Jensen (L-J culture negative for M. tuberculosis. Tuberculin skin test was negative. Respiratory symptoms disappeared in a week under antibiotics. Positive L-J cultures of knee punctation and favourable treatment outcome following standardized antituberculous treatment regimen confirmed the diagnosis of specific synovitis, which was also demonstrated by Magnetic Resonance Imaging (MRI. Conclusion. Tuberculous synovitis is important differencial diagnosis in patients with arthropathies and risk factors for TB in all the countries and all patients' ages even when tuberculin skin test is negative.

THE MAN CATEGORY IN PUBLIC POLICIES AND BRAZILIAN LAWS

Directory of Open Access Journals (Sweden)

Samantha Alflen Banin

2016-11-01

Full Text Available This article discusses the view of man as a gender category in public policies and national laws, especially those focused on violence against women. With this objective, it contextualizes the studies of feminisms and masculinities as theories and epistemology that guide the analysis of 17 official Brazilian documents selected for this study. This analysis seeks to clarify how the gendered man has been understood in various documents over the years. It discusses how the formulation of laws can provide a new accountability approach beyond the punishment of these men. It also investigates the regulation of some of the existing groups of men who have used violence against women in the country. It finalizes claiming the importance of these reflections for the debate on gender and masculinities in pursuit of a more effective system of prevention and eradication of violence against women. It discusses and argues in favor of both changing the way this category is addressed in official documents, and formalizing spaces for reflection for men who have used violence against women.

Free Man(7-9)GlcNAc2 is released during the biosynthesis pathway of N-linked glycans or from misfolded glycoproteins during the endoplasmic reticulum-associated degradation process and are reduced to Man5GlcNAc in the cytosol. In this form, free oligosaccharides can be transferred into the lysosomes to be degraded completely. α-Mannosidase (MAN2C1) is the enzyme responsible for the partial demannosylation occurring in the cytosol. It has been demonstrated that the inhibition of MAN2C1 expression induces accumulation of Man(8-9)GlcNAc oligosaccharides and apoptosis in vitro. We investigated the consequences caused by the lack of cytosolic α-mannosidase activity in vivo by the generation of Man2c1-deficient mice. Increased amounts of Man(8-9)GlcNAc oligosaccharides were recognized in all analyzed KO tissues. Histological analysis of the CNS revealed neuronal and glial degeneration with formation of multiple vacuoles in deep neocortical layers and major telencephalic white matter tracts. Enterocytes of the small intestine accumulate mannose-containing saccharides and glycogen particles in their apical cytoplasm as well as large clear vacuoles in retronuclear position. Liver tissue is characterized by groups of hepatocytes with increased content of mannosyl compounds and glycogen, some of them undergoing degeneration by hydropic swelling. In addition, lectin screening showed the presence of mannose-containing saccharides in the epithelium of proximal kidney tubules, whereas scattered glomeruli appeared collapsed or featured signs of fibrosis along Bowman's capsule. Except for a moderate enrichment of mannosyl compounds and glycogen, heterozygous mice were normal, arguing against possible toxic effects of truncated Man2c1. These findings confirm the key role played by Man2c1 in the catabolism of free oligosaccharides.

2000-01-01

The most likely accident in industrial installations is fire. 59 out of 100 accidents reported in 1999 describe a fire outbreak, the fire is either the initiating cause of the accident or the form into which the event eventually evolves. This article briefly describes the why and the wherefore of French regulations on fire prevention in installations presenting a risk for man and environment. The French system is based on the responsibility of the plant operator and on the result of inspections performed by authorities to check the conformity of the installation with current regulations.

Adaptive myelination from fish to man.

Science.gov (United States)

Baraban, Marion; Mensch, Sigrid; Lyons, David A

2016-06-15

Myelinated axons with nodes of Ranvier are an evolutionary elaboration common to essentially all jawed vertebrates. Myelin made by Schwann cells in our peripheral nervous system and oligodendrocytes in our central nervous system has been long known to facilitate rapid energy efficient nerve impulse propagation. However, it is now also clear, particularly in the central nervous system, that myelin is not a simple static insulator but that it is dynamically regulated throughout development and life. New myelin sheaths can be made by newly differentiating oligodendrocytes, and mature myelin sheaths can be stimulated to grow again in the adult. Furthermore, numerous studies in models from fish to man indicate that neuronal activity can affect distinct stages of oligodendrocyte development and the process of myelination itself. This begs questions as to how these effects of activity are mediated at a cellular and molecular level and whether activity-driven adaptive myelination is a feature common to all myelinated axons, or indeed all oligodendrocytes, or is specific to cells or circuits with particular functions. Here we review the recent literature on this topic, elaborate on the key outstanding questions in the field, and look forward to future studies that incorporate investigations in systems from fish to man that will provide further insight into this fundamental aspect of nervous system plasticity.

The term 'bionic' has been in existence since 1958, but only gained general recognition from the television series 'The Six Million Dollar Man'. Following a crash, the central figure in this series - test pilot Steve Austin - has an eye, an arm and both legs replaced by prostheses which make him stronger and faster than a normal person. This story is based on the science fiction book 'Cyborg' by Martin Caidin. In the world of comic books and films there are a number of examples of people who are given superhuman powers by having technological gadgets built in. Although the latter is not yet possible, the bionic human has now become reality.

Birth and development of the man-made gemstones in the 20th century are outlined. Manufacturing gemstones was initiated by the invention of corundum production, followed by production of rubies and sapphires. In 1950 GE Co. synthesized diamonds, after that, most gemstones were manufactured consequently by progress of technologies of single crystal growing and ceramic manufacturing. In the 21st century, steep growth in demand is not expected but it seems to keep steady growth and the importance and necessity of man-made gemstones may be increased because of global environmental issues. Man-made gemstones seem to have both personality and variety of characteristics. (NEDO)

House Dust Mite Allergen Regulates Constitutive Apoptosis of Normal and Asthmatic Neutrophils via Toll-Like Receptor 4.

Directory of Open Access Journals (Sweden)

Do Hyung Kim

Full Text Available House dust mites (HDMs induce allergic diseases such as asthma. Neutrophil apoptosis is an important process of innate immunity, and its dysregulation is associated with asthma. In this study, we examined the effects of HDM on constitutive apoptosis of normal and asthmatic neutrophils. Extract of Dermatophagoides pteronissinus (DP inhibited neutrophil apoptosis, but Dermatophagoides farinae extract had no effect. Anti-apoptotic signaling mediated by DP involves in TLR4, Lyn, PI3K, Akt, ERK, and NF-κB in normal neutrophils. DP delayed cleavage of procaspase 9 and procaspase 3 and the decrease in Mcl-1 expression. Supernatant collected from DP-treated normal neutrophils inhibited the constitutive apoptosis of normal neutrophils, and S100A8 and S100A9 were identified as anti-apoptotic proteins in the supernatant. S100A8 and S100A9 transduced the anti-apoptotic signal via TLR4, Lyn, PI3K, Akt, ERK, and NF-κB. DP also suppressed asthmatic neutrophil apoptosis and induced secretion of S100A8 and S100A9, which delayed the constitutive apoptosis. The anti-apoptotic effects of DP, S100A8 and S100A9 in asthmatic neutrophils are associated with TLR4, Lyn, PI3K, Akt, ERK, and NF-κB. The concentrations of S100A8 and S100A9 were significantly elevated in asthmatic bronchoalveolar lavage fluid (BALF when compared to normal BALF (p<0.01, but not in serum. S100A8 concentration in BALF was positively correlated with the number of BALF neutrophils and negatively correlated with FEV1(%. These findings improve our understanding of the role of HDM in regulation of neutrophil apoptosis in normal individuals and asthmatics and will enable elucidation of asthma pathogenesis.

Sulcova, J.; Jirasek, J.E.; Neuwirth, J.; Raboch, J.; Starka, L.

1978-01-01

The conversion of 3 H-testosterone and the uptake of 3 H-testosterone and 3 H-5α-dihydrotestosterone were investigated in pubic skin and pubic hair follicles of a XXY-man with inadequate pubic hair. The uptake of both androgens was demonstrated in the skin as well as in the hair follicles. Similarly the activity of steroid 5α-reductase was present in both tissues. The total conversion of 3 H-testosterone was 2-3 times higher in the patient than in control persons. In the XXY-man the major metabolites were 5α- and 5β-androstanediols, whereas in the normal men 5α-dihydrotestosterone and 4-androstenedione were mainly formed from testosterone. An explanation of the inadequate growth of pubic hair in our patient seems to be related to a conversion of testosterone - at its low plasma level - to its relatively inactive metabolites. (author)

Let-7b Regulates Myoblast Proliferation by Inhibiting IGF2BP3 Expression in Dwarf and Normal Chicken

Science.gov (United States)

Lin, Shumao; Luo, Wen; Ye, Yaqiong; Bekele, Endashaw J.; Nie, Qinghua; Li, Yugu; Zhang, Xiquan

2017-01-01

The sex-linked dwarf chicken is caused by the mutation of growth hormone receptor (GHR) gene and characterized by shorter shanks, lower body weight, smaller muscle fiber diameter and fewer muscle fiber number. However, the precise regulatory pathways that lead to the inhibition of skeletal muscle growth in dwarf chickens still remain unclear. Here we found a let-7b mediated pathway might play important role in the regulation of dwarf chicken skeletal muscle growth. Let-7b has higher expression in the skeletal muscle of dwarf chicken than in normal chicken, and the expression of insulin-like growth factor 2 mRNA binding protein 3 (IGF2BP3), which is a translational activator of IGF2, showed opposite expression trend to let-7b. In vitro cellular assays validated that let-7b directly inhibits IGF2BP3 expression through binding to its 3′UTR region, and the protein level but not mRNA level of IGF2 would be reduced in let-7b overexpressed chicken myoblast. Let-7b can inhibit cell proliferation and induce cell cycle arrest in chicken myoblast through let-7b-IGF2BP3-IGF2 signaling pathway. Additionally, let-7b can also regulate skeletal muscle growth through let-7b-GHR-GHR downstream genes pathway, but this pathway is non-existent in dwarf chicken because of the deletion mutation of GHR 3′UTR. Notably, as the loss binding site of GHR for let-7b, let-7b has enhanced its binding and inhibition on IGF2BP3 in dwarf myoblast, suggesting that the miRNA can balance its inhibiting effect through dynamic regulate its binding to target genes. Collectively, these results not only indicate that let-7b can inhibit skeletal muscle growth through let-7b-IGF2BP3-IGF2 signaling pathway, but also show that let-7b regulates myoblast proliferation by inhibiting IGF2BP3 expression in dwarf and normal chickens.

A historical overview of the electrical power systems in the US manned and some US unmanned spacecraft

Science.gov (United States)

Maisel, J. E.

1984-01-01

A historical overview of electrical power systems used in the U.S. manned spacecraft and some of the U.S. unmanned spacecraft is presented in this investigation. A time frame of approximately 25 years, the period for 1959 to 1984, is covered in this report. Results indicate that the nominal bus voltage was 28 volts dc in most spacecraft and all other voltage levels were derived from this voltage through such techniques as voltage inversion or rectification, or a combination. Most spacecraft used solar arrays for the main source of power except for those spacecraft that had a relatively short flight duration, or deep spaceprobes that were designed for very long flight duration. Fuel cells were used on Gemini, Apollo, and Space Shuttle (short duration flights) while radioisotope thermoelectric generators were employed on the Pioneer, Jupiter/Saturn, Viking Lander, and Voyager spacecraft (long duration flights). The main dc bus voltage was unregulated on the manned spacecraft with voltage regulation provided at the user loads. A combination of regulated, semiregulated, and unregulated buses were used on the unmanned spacecraft depending on the type of load. For example, scientific instruments were usually connected to regulated buses while fans, relays, etc. were energized from an unregulated bus. Different forms of voltage regulation, such as shunt, buck/boot, and pulse-width modulated regulators, were used. This report includes a comprehensive bibliography on spacecraft electrical power systems for the space programs investigated.

Symbolism in prehistoric man.

Science.gov (United States)

Facchini, F

2000-12-01

The aptitude for symbolization, characteristic of man, is revealed not only in artistic representations and funerary practices. It is exhibited by every manifestation of human activity or representation of natural phenomena that assumes or refers to a meaning. We can recognize functional symbolism (tool-making, habitative or food technology), social symbolism, (language and social communication) and spiritual symbolism (funerary practices and artistic expressions). On the basis of these concepts, research into symbolism in prehistoric man allows us to recognize forms of symbolism already in the manifestations of the most ancient humans, starting with Homo habilis (or rudolfensis). Toolmaking, social organization and organization of the territory are oriented toward survival and the life of the family group. They attest to symbolic behaviors and constitute symbolic systems by means of which man expresses himself, lives and transmits his symbolic world. The diverse forms of symbolism are discussed with reference to the different phases of prehistoric humanity.

Kidney function in normal man during short-term growth hormone infusion

DEFF Research Database (Denmark)

Parving, H H; Noer, I; Mogensen, C E

1978-01-01

Kidney function was studied in 9 normal males before and during a 2 h growth hormone (GH) infusion of 50 ng/kg/min. The following variables were measured during each 20 min clearance period: glomerular filtration rate, GFR, effective renal plasma flow, RPF (steady state infusion technique...... with urinary collections using [125I]iothalamate and [131I]iodohippurate), and urinary albumin and beta2-microglobulin excretion rates (radioimmunoassays). The GH infusion resulted in a 10-fold increase in plasma GH concentration. All the above mentioned variables remained practically unchanged during...... the infusion except for a small (-5%) but significant decrease in renal plasma flow (P less than 0.01). Our negative results contrast to the findings of increased GFR and RPF during prolonged GH administration and suggest that GH requires several hours or days for its renal effects to become manifest....

A Time consistent model for monetary value of man-sievert

International Nuclear Information System (INIS)

Na, S.H.; Kim, Sun G.

2008-01-01

Full text: Performing a cost-benefit analysis to establish optimum levels of radiation protection under the ALARA principle, we introduce a discrete stepwise model to evaluate man-sievert monetary value of Korea. The model formula, which is unique and country-specific, is composed of GDP, the nominal risk coefficient for cancer and hereditary effects, the aversion factor against radiation exposure, and the average life expectancy. Unlike previous researches on alpha-value assessment, we showed different alpha values optimized with respect to various ranges of individual dose, which would be more realistic and applicable to the radiation protection area. Employing economically constant term of GDP we showed the real values of man-sievert by year, which should be consistent in time series comparison even under price level fluctuation. GDP deflators of an economy have to be applied to measure one's own consistent value of radiation protection by year. In addition, we recommend that the concept of purchasing power parity should be adopted if it needs international comparison of alpha values in real terms. Finally, we explain the way that this stepwise model can be generalized simply to other countries without normalizing any country-specific factors. (author)

stimuli may be more reproducible. A methodological study also demonstrated that habituation to experimental pain developed as the study proceeded. Habituation is common in experimental pain models, and dividing analgesics and placebo evenly between the study days is one way of eliminating the effects......Human experimental pain models are important tools in pain research. The primary aims of pain research in normal man is 1) to provide insight in pain mechanisms, 2) to provide a rational basis for clinical trials of pain relieving interventions, and 3) to confirm the anti-nociceptive effects...... demonstrated in animal models. Most often clinical pain is due to tissue damage leading to acute inflammation and hyperalgesia, but only few human pain models have examined pain responses in injured tissues. Therefore, models with controlled and reversible tissue trauma are needed. The human burn model...

Man-made climate change: an overview

The first major man-made environmental problem was the soil acidification, caused primarily by the massive industrial emissions of sulphur dioxide. Then came the problem of ozone depletion, caused by the emissions of man-made halocarbons. More recently, the possibility of man-made climate change has received a lot of attention. These three man-made problems are interconnected in fundamental ways and require for their solution interdisciplinary and international approach. Narrowing of the scientific uncertainties connected with the problems mentioned above can be expected through international `Global Change` programmes such as the World Climate Research Programme (WCRP) and the International Geosphere-Biosphere Programme (IGBP). Periodic assessments of the type produced by the IPCC will clearly be needed. Also in the future such assessments should form the scientific basis for international negotiations and conventions on the climate change issue

Expression of a TGF-{beta} regulated cyclin-dependent kinase inhibitor in normal and immortalized airway epithelial cells

Energy Technology Data Exchange (ETDEWEB)

Tierney, L.A.; Bloomfield, C.; Johnson, N.F. [and others

1995-12-01

Tumors arising from epithelial cells, including lung cancers are frequently resistant to factors that regulate growth and differentiation in normal in normal cells. Once such factor is transforming growth factor-{Beta} (TGF-{Beta}). Escape from the growth-inhibitory effects of TGF-{Beta} is thought to be a key step in the transformation of airway epithelial cells. most lung cancer cell lines require serum for growth. In contrast, normal human bronchial epithelial (NHBE) cells are exquisitely sensitive to growth-inhibitory and differentiating effects of TGF-{Beta}. The recent identification of a novel cyclin-dependent kinase inhibitor, p15{sup INK4B}, which is regulated by TGF-{Beta}, suggests a mechanism by which TGF-{Beta} mediates growth arrest in NHBE cells. The purpose of this study was two-fold: (1) to determine if p15{sup INK4B} is induced by TGF-{Beta} in NHBE cells or immortalized bronchial epithelial (R.1) cells and if that induction corresponds to a G1/S cell-cycle arrest; (2) to determine the temporal relationship between p15{sup INK4B} induction, cell-cycle arrest, and the phosphorylation state of the pRB because it is thought that p15{sup INK4B} acts indirectly by preventing phosphorylation of the RB gene product. In this study, expression of p15{sup INK4B} was examined in NHBE cells and R.1 cells at different time intervals following TGF-{Beta} treatment. The expression of this kinase inhibitor and its relationship to the cell and the pRb phosphorylation state were examined in cells that were both sensitive (NHBE) and resistant (R.1) to the effects of TGF-{Beta}. These results suggest that the cyclin-dependent kinase inhibitor, p15{sup INK4B}, is involved in airway epithelial cell differentiation and that loss or reduction of expression plays a role in the resistance of transformed or neoplastic cells to the growth-inhibitory effects of TGF-{Beta}.

Epstein-Barr virus (EBV) LMP2A alters normal transcriptional regulation following B-cell receptor activation

International Nuclear Information System (INIS)

Portis, Toni; Longnecker, Richard

2004-01-01

The latent membrane protein 2A (LMP2A) of Epstein-Barr virus (EBV) is an important mediator of viral latency in infected B-lymphocytes. LMP2A inhibits B-cell receptor (BCR) signaling in vitro and allows for the survival of BCR-negative B cells in vivo. In this study, we compared gene transcription in BCR-activated B cells from non-transgenic and LMP2A Tg6 transgenic mice. We found that the transcriptional induction and down-regulation of many genes that normally occurs in B cells following BCR activation did not occur in B cells from LMP2A Tg6 transgenic mice. Furthermore, LMP2A induced the expression of various transcription factors and genes associated with DNA/RNA metabolism, which may allow for the altered transcriptional regulation observed in BCR-activated B cells from LMP2A Tg6 mice. These results suggest that LMP2A may inhibit the downstream effects of BCR signaling by directly or indirectly altering gene transcription to ensure EBV persistence in infected B cells

Nuclear fuel: the thinking man's alternative

Chamberlain, N.

1989-01-01

'Nuclear Fuel ' The Thinking Man's Alternative' is the title of the 55th Melchett Lecture given by Neville Chamberlain, Chief Executive of British Nuclear Fuels plc. This article is based on the address, the essence of which is that the case for nuclear power should be based upon an appreciation of the totality and sophistication of man's handling of his energy needs - not on a glib catch-phase or on a simple political dogma or on an economic argument. Arguments in favour of nuclear power were discussed. The conclusion was that nuclear energy is the thinking man's alternative because only thinking man could have and can develop it; secondly, only thinking men should be authorized to exploit and control it; thirdly, a thinking person will appreciate that, properly thought out and controlled, it must be the most important source of future energy for the benefit of mankind.

Intake and body content of actinides (Pu, Th, U) and a related alpha-emitting nuclide (Ra) were studied along with physiological aspects of Reference Japanese Man as the basic model for dosimetry. The ultimate purpose of the program was to examine applicability of the ICRP models and parameters (for workers) to members of the public. The result of an interlaboratory comparison of 239 Pu+ 240 Pu determination including our result was published. Alpha spectrometric determinations of 226 Ra in bone yielded representative adult bone concentration levels in Tokyo, 0.42 (mean) and 0.35 (median) mBq/g ash. The Ra-Ca O.R. (bone-diet) was obtained which was similar to the values in Sapporo and Kyoto. Specific effective energies for alpha radiation from 226 Ra and its daughters were calculated using the ICRP dosimetric model for bone and masses of source and target organs of Reference Japanese Man. Annual dose equivalents in red marrow and bone surfaces were 10 and 145 μSv, respectively as estimated from the median adult bone Ra concentration. Diet samples collected by the duplicate portion method from 31 locations in Japan in summer and winter, 1981-2 were analysed for 232 Th and 238 U by the newly developed ICP-MS technique. The daily intake per person of 232 Th and 238 U were 1.7 and 8.8 mBq, respectively. Using IDES with Japanese physical parameters and other parameters of ICRP, weighted dose equivalent commitments for single year intakes were estimated as 0.4 μSv for 232 Th and 0.3 μSv for 238 U. Reference Japanese data including the adult, adolescent, child and infant of both sexes was extensively studied by Tanaka as part of the activities associated with the ICRP Task Group on Reference Man Revision. Normal data on the physical measurements, mass and dimensions of internal organs and body surfaces and some of the body composition were analyzed in relation to the nutritional conditions of the Japanese population.

Human capabilities in space. [man machine interaction

Science.gov (United States)

Nicogossian, A. E.

1984-01-01

Man's ability to live and perform useful work in space was demonstrated throughout the history of manned space flight. Current planning envisions a multi-functional space station. Man's unique abilities to respond to the unforeseen and to operate at a level of complexity exceeding any reasonable amount of previous planning distinguish him from present day machines. His limitations, however, include his inherent inability to survive without protection, his limited strength, and his propensity to make mistakes when performing repetitive and monotonous tasks. By contrast, an automated system does routine and delicate tasks, exerts force smoothly and precisely, stores, and recalls large amounts of data, and performs deductive reasoning while maintaining a relative insensitivity to the environment. The establishment of a permanent presence of man in space demands that man and machines be appropriately combined in spaceborne systems. To achieve this optimal combination, research is needed in such diverse fields as artificial intelligence, robotics, behavioral psychology, economics, and human factors engineering.

2007-01-01

Typhoon Man-Yi was pummeling the Japanese island of Okinawa with winds between 230 and 295 kilometers per hour (125-160 knots, 144-184 miles per hour) and heavy rain on the morning of July 13, 2007, when the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA's Terra satellite captured this image. The immense storm covered hundreds of kilometers with spiraling bands of thunderstorms, though it had lost the distinctive cloud-free eye it exhibited the day before. Typhoons are common in Japan, but powerful typhoons usually strike the island nation later in the year. The Japan Meteorological Agency said that Man-Yi is the fourth typhoon of the 2007 season and may be the most powerful ever observed in the northwest Pacific in July, reported Kyodo News. The Joint Typhoon Warning Center expected the typhoon to strike Kyushu, a southern Japanese island, on July 14, and then curve northeast along the eastern shore of Japan. By the time the storm reaches Tokyo on July 15, it should be degraded to a tropical storm. As of July 13, Typhoon Man-Yi had injured eight and flooded twenty houses in Okinawa, and forced airlines to cancel hundreds of flights, said Kyodo News. The storm was expected to bring heavy rain to Japan's Pacific coast. NASA image created by Jesse Allen, using data provided courtesy of the MODIS Rapid Response team.

Man-machine supervision

International Nuclear Information System (INIS)

Montmain, J.

2005-01-01

Today's complexity of systems where man is involved has led to the development of more and more sophisticated information processing systems where decision making has become more and more difficult. The operator task has moved from operation to supervision and the production tool has become indissociable from its numerical instrumentation and control system. The integration of more and more numerous and sophisticated control indicators in the control room does not necessary fulfill the expectations of the operation team. It is preferable to develop cooperative information systems which are real situation understanding aids. The stake is not the automation of operators' cognitive tasks but the supply of a reasoning help. One of the challenges of interactive information systems is the selection, organisation and dynamical display of information. The efficiency of the whole man-machine system depends on the communication interface efficiency. This article presents the principles and specificities of man-machine supervision systems: 1 - principle: operator's role in control room, operator and automation, monitoring and diagnosis, characteristics of useful models for supervision; 2 - qualitative reasoning: origin, trends, evolutions; 3 - causal reasoning: causality, causal graph representation, causal and diagnostic graph; 4 - multi-points of view reasoning: multi flow modeling method, Sagace method; 5 - approximate reasoning: the symbolic numerical interface, the multi-criteria decision; 6 - example of application: supervision in a spent-fuel reprocessing facility.

In laboratory animals, prostaglandins have been shown to act as endogenous neuromodulators of central dopamine (DA) activity. To examine the interaction between prostaglandins and DA in man, the effect of a prostaglandin synthesis inhibitor, indomethacin, was studied on plasma concentrations of the DA metabolite, homovanillic acid (pHVA). Indomethacin (150 mg PO) as compared to placebo significantly elevated mean pHVA concentrations in eight normal subjects. Results of this study support the hypothesis that, as in animals, inhibition of prostaglandin synthesis increases central DA turnover in man.

Up-regulation of β-adrenoreceptors by drugs which cause depression

Brand, L.; Van Rooyen, J.M.; Offermeier, J.

1988-01-01

A number of drugs associated with depressive episodes in man were investigated for their effects on rat cortical β-adrenoceptors, in view of the down-regulation of β-adrenoceptors caused by chronic administration of anti-depressant drugs. Scatchard analyses of [ 3 H]dihydro-alprenolol binding data provided B max and K D values for the cortical β-adrenoceptors. Up-regulation of the receptors occurred after daily injections of phenobarbitone for seven days (by 55%), pentobarbitone (by 143%), reserpine (by 82%) and propranolol (by 64%). β-adrenoceptors were not affected by daily injections of clonidine, chlorpromazine and flupenthixol for seven days. This work confirms the up-regulatory effect on β-adrenoceptors of certain drugs which produce depressions in man

SOCIO-EDUCATIONAL ASPECTS OF THE WORKING MAN FORMATION.

Full Text Available The paper analyzes a new for the Russian anthropology concept of the «working man», introduced in the Urals along with the propagation of a social and political movement «For the Working Man Protection»; the semantic content of the «man» and «labor» notions being observed as well as the process and problems of the working man formation in the modern world.The author emphasizes the asymmetry of the socio-economic and vocational educational infrastructure, along with the contradictions between the labor market demands for the technical and technological profile workers and the existing educational qualification structure of vocational schools.In author's opinion, the disorganization of labor training in comprehensive school and deficiencies of vocational education hinder the process of the industrial working man formation. The professional orientation system is criticized for being unable to meet the demands of modern economy and provide the young people with the adequate concept of the working career.For overcoming the above problems affecting the working man formation, the paper recommends modernization of the labor training system in comprehensive schools, reformation of vocational training, and renovation of professional orientation system. The special emphasis is given to the continuing training of the working man. 

Reference Man for Asians as well as for Europeans-A change in the ICRP concept of Reference Man

International Nuclear Information System (INIS)

Tanaka, Gi-ichiro

1990-01-01

ICRP Reference Man, according to the definition, is primarily for Caucasoid populations (Western Europeans and North Americans) that contribute only 13 per cent of the world population. A speculative world population dose will, assuming a uniform exposure all over the world at a level of 10 μSv, be 50 k man Sv in total. Of this, all regions of Caucasoid populations may contribute by 22 per cent maximum. Asian populations will share about 58 per cent (29 k man Sv) of the world population dose. About eighty per cents in total of the world population can be convered by scientific dose assessment, if Reference Man data for Asians are made available. Thus the importance of establishing Asian Reference Man should be evident. The important point of characteristics of Asians is that they are 'Vegetarians' as compared to Westerners, which suggests different pathways with respect to transfer of radionuclides from foods to the human body. Therefore it is required to determine accurate and suitable parameters relevant to dose assessment. Considering the above, contribution of Japan in science and technology to Asian countries with 'knowhows' accumulated may be of a most urgent matter. (author)

Gene expression signatures affected by ethanol and/or nicotine in normal human normal oral keratinocytes (NHOKs

Directory of Open Access Journals (Sweden)

Jeffrey J. Kim

2014-12-01

Full Text Available It has been reported that nicotine/alcohol alters epigenetic control and leads to abrogated DNA methylation and histone modifications, which could subsequently perturb transcriptional regulation critically important in cellular transformation. The aim of this study is to determine the molecular mechanisms of nicotine/alcohol-induced epigenetic alterations and their mechanistic roles in transcriptional regulation in human adult stem cells. We hypothesized that nicotine/alcohol induces deregulation of epigenetic machinery and leads to epigenetic alterations, which subsequently affect transcriptional regulation in oral epithelial stem cells. As an initiating step we have profiled transcriptomic alterations induced by the combinatory administration of EtOH and nicotine in primary normal human oral keratinocytes. Here we provide detailed experimental methods, analysis and information associated with our data deposited into Gene Expression Omnibus (GEO under GSE57634. Our data provide comprehensive transcriptomic map describing molecular changes induced by EtOH and nicotine on normal human oral keratinocytes.

Full Text Available A pergunta título deste trabalho retoma o slogan “Ser diferente é normal”, que é parte da campanha criada para uma organização não-governamental que atende portadores de Síndrome de Down. O objetivo é a inclusão social da pessoa com deficiência e o primeiro passo foi propor a inclusão de um grupo de diferentes no grupo dito normal. No vídeo de lançamento da campanha, o diferente, identificado como normal, é mostrado por meio de exemplos – um negro com cabelo black-power, um skin-head, um corpo tatuado, um corpo feminino halterofílico, uma família hippie, uma garota com síndrome de Down. A visão da adolescente dançando reduz, de certo modo, o efeito imaginário que vai além da síndrome, uma vez que apenas o corpo com seus olhinhos puxados se destacam, e não se interrogam questões cognitivas. Minha proposta é refletir sobre o estatuto paradoxal do exemplo, tal como é trabalhado nesse vídeo: se, por definição, um exemplo mostra de fato seu pertencimento a uma classe, pode-se concluir que é exatamente por ser exemplar que ele se encontra fora dela, no exato momento em que a exibe e define. The question in the title of this paper refers to the slogan "ser diferente é normal" ("It´s normal to be different", which is part of a campaign created for a NGO that supports people with Down syndrome. The objective of the campaign is to promote the social inclusion of individuals with Down syndrome, and the first step was to propose the inclusion of a group of "differents" in the so-called normal group. The film launching the campaign shows the different identified as normal by means of examples: a black man exhibiting blackpower haircut, a skin-head, a tattooed body, an over-athletic female body, a hippie family and a girl with Down syndrome. The vision of the dancing teenager lessens the imaginary effect that surpasses the syndrome, since only her body and her little oriental eyes stand out and no cognitive issues are

Hyperthyroidism from autoimmune thyroiditis in a man with type 1 diabetes mellitus: a case report

Hirsch Irl B

2011-07-01

Full Text Available Abstract Introduction The presentation, diagnosis, clinical course and treatment of a man with hyperthyroidism secondary to autoimmune thyroiditis in the setting of type 1 diabetes mellitus has not previously been described. Case presentation A 32-year-old European-American man with an eight-year history of type 1 diabetes mellitus presented with an unintentional 22-pound weight loss but an otherwise normal physical examination. Laboratory studies revealed a suppressed thyroid-stimulating hormone concentration and an elevated thyroxine level, which are consistent with hyperthyroidism. His anti-thyroid peroxidase antibodies were positive, and his thyroid-stimulating immunoglobulin test was negative. Uptake of radioactive iodine by scanning was 0.5% at 24 hours. The patient was diagnosed with autoimmune thyroiditis. Six weeks following his initial presentation he became clinically and biochemically hypothyroid and was treated with thyroxine. Conclusion This report demonstrates that autoimmune thyroiditis presenting as hyperthyroidism can occur in a man with type 1 diabetes mellitus. Autoimmune thyroiditis may be an isolated manifestation of autoimmunity or may be part of an autoimmune polyglandular syndrome. Among patients with type 1 diabetes mellitus who present with hyperthyroidism, Graves' disease and other forms of hyperthyroidism need to be excluded as autoimmune thyroiditis can progress quickly to hypothyroidism, requiring thyroid hormone replacement therapy.

Development of the mathematical phantom of the brazilian man for internal dosimetry calculations

International Nuclear Information System (INIS)

Guimaraes, Maria Ines Calil Cury.

1995-01-01

This work covers the theory and construction of a Mathematical Phantom of the Brazilian, to be used in internal dosimetry. To obtain this it was necessary to develop antropometric data of mass and height for Brazilian man between 20 and 40 years old. Through Monte Carlo Method, and applying the Specific Absorbed Fraction (SAF) formalism, it was possible determine the fraction internal organs such as bones, skin and total body. The results obtained from SAF are primordial in nuclear medicine and great value in the calculation of the dose received by workers exposed and in accidental cases, to a rapid evaluation of the received by a simple person. Through SAF, the references obtained for the Brazilian man, can be noted when compared to the phantom calculated by Snyder, which proposed to represent the international reference man, showed by ICRP-23 publication, that the determined SAF of the whole body does not exceed 15% between the two phantoms, agreeing with the allowed international norms error margin permitted. The differences between the two models appear, when the numbers are presented for individual organs, where the emission origin are the lungs and taken as target, the red and yellow marrows, for an energy of 10 KeV. The result obtained is that these two marrows receive 64% more absorbed fractions in the Brazilian model than in the international model. These numbers are considered trustfully because the coefficient of variation does not exceed 7%, value that in under 50%, which makes the coefficient of variation not trustfully, this is considered out of the normal distribution. Facts like these and may others, showed in this work, determine the necessity to calculate a specific mathematical model for the Brazilian man. (author). 51 refs., 40 figs., 9 tabs

ESR dating results for samples of synchronous animal tooth with the skull of Hexian-Man in the lower part of the second layer show that the age of Hexian-Man is about 300(299.80) ka, corresponding to the late stage of Peiking-Man (the HIII skull of Peking-Man). The ages of Hexian-Man's Fauna are 150-300 ka, corresponding to those of the 2nd-3rd-4th layers of Peking-Man's Cave

Emblem for the third manned Skylab mission - Skylab 4

Science.gov (United States)

1973-01-01

This is the emblem for the third manned Skylab mission. It will be a mission of up to 56 days. The symbols in the patch refer to the three major areas of investigation proposed in the mission. The tree represents man's natural environment and relates directly to the Skylab mission objectives of advancing the study of Earth resources. The hydrogen atom, as the basic building block of the universe, represents man's exploration of the physical world, his application of knowledge, and his development of technology. Since the Sun is composed primarily of hydrogen, it is appropriate that the symbol refers to the solar physics mission objectives. The human silhouette represents mankind and the human capacity to direct technology with a wisdom tempered by regard for his natural environment. It also directly relates to the Skylab medical studies of man himself. The rainbow, adopted from the Biblical story of the flood, symbolizes the promise that is offered man. It embraces man and extends to t

Advanced transportation system study: Manned launch vehicle concepts for two way transportation system payloads to LEO

Science.gov (United States)

Duffy, James B.

1993-01-01

The purpose of the Advanced Transportation System Study (ATSS) task area 1 study effort is to examine manned launch vehicle booster concepts and two-way cargo transfer and return vehicle concepts to determine which of the many proposed concepts best meets NASA's needs for two-way transportation to low earth orbit. The study identified specific configurations of the normally unmanned, expendable launch vehicles (such as the National Launch System family) necessary to fly manned payloads. These launch vehicle configurations were then analyzed to determine the integrated booster/spacecraft performance, operations, reliability, and cost characteristics for the payload delivery and return mission. Design impacts to the expendable launch vehicles which would be required to perform the manned payload delivery mission were also identified. These impacts included the implications of applying NASA's man-rating requirements, as well as any mission or payload unique impacts. The booster concepts evaluated included the National Launch System (NLS) family of expendable vehicles and several variations of the NLS reference configurations to deliver larger manned payload concepts (such as the crew logistics vehicle (CLV) proposed by NASA JSC). Advanced, clean sheet concepts such as an F-1A engine derived liquid rocket booster (LRB), the single stage to orbit rocket, and a NASP-derived aerospace plane were also included in the study effort. Existing expendable launch vehicles such as the Titan 4, Ariane 5, Energia, and Proton were also examined. Although several manned payload concepts were considered in the analyses, the reference manned payload was the NASA Langley Research Center's HL-20 version of the personnel launch system (PLS). A scaled up version of the PLS for combined crew/cargo delivery capability, the HL-42 configuration, was also included in the analyses of cargo transfer and return vehicle (CTRV) booster concepts. In addition to strictly manned payloads, two-way cargo

Effect of physiologic hyperinsulinemia on skeletal muscle protein synthesis and breakdown in man

International Nuclear Information System (INIS)

Gelfand, R.A.; Barrett, E.J.

1987-01-01

Although insulin stimulates protein synthesis and inhibits protein breakdown in skeletal muscle in vitro, the actual contribution of these actions to its anabolic effects in man remains unknown. Using the forearm perfusion method together with systemic infusion of L-[ring-2,6-3H]phenylalanine and L-[1- 14 C]leucine, we measured steady state amino acid exchange kinetics across muscle in seven normal males before and in response to a 2-h intraarterial infusion of insulin. Postabsorptively, the muscle disposal (Rd) of phenylalanine (43 +/- 5 nmol/min per 100 ml forearm) and leucine (113 +/- 13) was exceeded by the concomitant muscle production (Ra) of these amino acids (57 +/- 5 and 126 +/- 9 nmol/min per dl, respectively), resulting in their net release from the forearm (-14 +/- 4 and -13 +/- 5 nmol/min per dl, respectively). In response to forearm hyperinsulinemia (124 +/- 11 microU/ml), the net balance of phenylalanine and leucine became positive (9 +/- 3 and 61 +/- 8 nmol/min per dl, respectively (P less than 0.005 vs. basal). Despite the marked increase in net balance, the tissue Rd for both phenylalanine (42 +/- 2) and leucine (124 +/- 9) was unchanged from baseline, while Ra was markedly suppressed (to 33 +/- 5 and 63 +/- 9 nmol/min per dl, respectively, P less than 0.01). Since phenylalanine is not metabolized in muscle (i.e., its only fates are incorporation into or release from protein) these results strongly suggest that in normal man, physiologic elevations in insulin promote net muscle protein anabolism primarily by inhibiting protein breakdown, rather than by stimulating protein synthesis

Moses, S.C.; Baker, S.R.; Seldin, M.F.

1983-01-01

A homosexual man with A.I.D.S. (acquired immunologic deficiency syndrome) and pneumocystis infestation was found to have diffuse Ga-67 uptake in the lungs with a coincident negative chest x-ray. While Ga-67 accumulates diffusely in the lungs in a variety of conditions, the present case is the first described in a patient with A.I.D.S. in which Ga-67 was positive before roentgenographic abnormalities were demonstrated. Thus, the use of Ga-67 scan, when A.I.D.S. is suspected, could help establish a diagnosis more promptly

Full Text Available Abstract Background Simulation training has potential in developing clinical skills in pre-clinical medical students, but there is little evidence on its effectiveness. Methods Twenty four first year graduate entry preclinical medical students participated in this crossover study. They were divided into two groups, one performed chest examination on each other and the other used SimMan. The groups then crossed over. A pretest, midtest and post-test was conducted in which the students answered the same questionnaire with ten questions on knowledge, and confidence levels rated using a 5 point Likert scale. They were assessed formatively using the OSCE marking scheme. At the end of the session, 23 students completed a feedback questionnaire. Data was analyzed using one-way ANOVA and independent t-test. Results When the two groups were compared, there was no significant difference in the pretest and the post-test scores on knowledge questions whereas the midtest scores increased significantly (P Mean confidence ratings increased from the pretest to midtest and then further in the post-test for both groups. Their confidence ratings increased significantly in differentiating between normal and abnormal signs [Group starting with SimMan, between pretest and midtest (P= 0.01 and group starting with peer examination, between midtest and post-test (P=0.02]. When the students’ ability to perform examination on each other for both groups was compared, there was a significant increase in the scores of the group starting with SimMan (P=0.007. Conclusions This pilot study demonstrated a significant improvement in the students’ knowledge and competence to perform chest examination after simulation with an increase in the student’s perceived levels of confidence. Feedback from the students was extremely positive. SimMan acts as a useful adjunct to teach clinical skills to preclinical medical students by providing a simulated safe environment and thus aids

Peillon, F; Philippon, J; Brandi, A M; Fohanno, D; Laplane, D; Dubois, M P; Decourt, J

1979-12-01

A prolactin-secreting pituitary adenoma was removed trans-sphenoidally from a 37 years old man with gigantism (218 cm). Serum levels of prolactin (PRL) were elevated pre-operatively and decreased after administration of L-Dopa with no increase after TRH as is usually observed in PRL-secreting adenomas. Growth hormone (GH) and somatomedin serum levels were normal with no modification of GH after insulin hypoglycemia, oral glucose loading or L-Dopa. Morphological examination of the tumour demonstrated the presence of lactotrophs by light and electron microscopy and by immunofluorescense staining. No somatotrophs were found. In this unique case, the relationship between a PRL-secreting adenoma and gigantism is discussed.

Licausi, Francesco; Giorgi, Federico Manuel; Schmälzlin, Elmar; Usadel, Björn; Perata, Pierdomenico; van Dongen, Joost Thomas; Geigenberger, Peter

2011-11-01

The occurrence of hypoxic conditions in plants not only represents a stress condition but is also associated with the normal development and growth of many organs, leading to adaptive changes in metabolism and growth to prevent internal anoxia. Internal oxygen concentrations decrease inside growing potato tubers, due to their active metabolism and increased resistance to gas diffusion as tubers grow. In the present work, we identified three hypoxia-responsive ERF (StHRE) genes whose expression is regulated by the gradual decrease in oxygen tensions that occur when potato tubers grow larger. Increasing the external oxygen concentration counteracted the modification of StHRE expression during tuber growth, supporting the idea that the actual oxygen levels inside the organs, rather than development itself, are responsible for the regulation of StHRE genes. We identified several sugar metabolism-related genes co-regulated with StHRE genes during tuber development and possibly involved in starch accumulation. All together, our data suggest a possible role for low oxygen in the regulation of sugar metabolism in the potato tuber, similar to what happens in storage tissues during seed development.

RevManHAL: towards automatic text generation in systematic reviews.

Science.gov (United States)

Torres Torres, Mercedes; Adams, Clive E

2017-02-09

Systematic reviews are a key part of healthcare evaluation. They involve important painstaking but repetitive work. A major producer of systematic reviews, the Cochrane Collaboration, employs Review Manager (RevMan) programme-a software which assists reviewers and produces XML-structured files. This paper describes an add-on programme (RevManHAL) which helps auto-generate the abstract, results and discussion sections of RevMan-generated reviews in multiple languages. The paper also describes future developments for RevManHAL. RevManHAL was created in Java using NetBeans by a programmer working full time for 2 months. The resulting open-source programme uses editable phrase banks to envelop text/numbers from within the prepared RevMan file in formatted readable text of a chosen language. In this way, considerable parts of the review's 'abstract', 'results' and 'discussion' sections are created and a phrase added to 'acknowledgements'. RevManHAL's output needs to be checked by reviewers, but already, from our experience within the Cochrane Schizophrenia Group (200 maintained reviews, 900 reviewers), RevManHAL has saved much time which is better employed thinking about the meaning of the data rather than restating them. Many more functions will become possible as review writing becomes increasingly automated.

CaveMan Enterprise version 1.0 Software Validation and Verification.

Energy Technology Data Exchange (ETDEWEB)

Hart, David

2014-10-01

The U.S. Department of Energy Strategic Petroleum Reserve stores crude oil in caverns solution-mined in salt domes along the Gulf Coast of Louisiana and Texas. The CaveMan software program has been used since the late 1990s as one tool to analyze pressure mea- surements monitored at each cavern. The purpose of this monitoring is to catch potential cavern integrity issues as soon as possible. The CaveMan software was written in Microsoft Visual Basic, and embedded in a Microsoft Excel workbook; this method of running the CaveMan software is no longer sustainable. As such, a new version called CaveMan Enter- prise has been developed. CaveMan Enterprise version 1.0 does not have any changes to the CaveMan numerical models. CaveMan Enterprise represents, instead, a change from desktop-managed work- books to an enterprise framework, moving data management into coordinated databases and porting the numerical modeling codes into the Python programming language. This document provides a report of the code validation and verification testing.

Stroma-tumor communication participates in the pathogenesis of endometrial carcinomas. In previous studies, we found that normal stromal cells inhibited the growth of endometrial carcinoma cells. Here, we investigated the role of normal stromal cells in the epithelial-mesenchymal transition (EMT) of endometrial carcinoma cells and explored the possible mechanism implied. We found that conditioned medium (CM) by normal endometrial stromal cells (NSC) reduced cell growth and induced cell apoptosis in Ishikawa cells. CM by NSC inhibited 17β-estradiol-induced cell growth and apoptosis decrease in Ishikawa cells. Moreover, CM by NSC inhibited the migration and invasion, and 17β-estradiol-induced migration and invasion in Ishikawa cells. Meanwhile, CM by NSC decreased Slug expression and 17β-estradiol-induced Slug expression, increased E-cadherin expression and abolished 17β-estradiol-induced E-cadherin reduction in Ishikawa cells. In conclusion, normal stromal factors can inhibit 17β-estradiol-induced cell proliferation and apoptosis inhibition, and abolished 17β-estradiol-induced EMT in endometrial cancer cell via regulating E-cadherin and Slug expression.

It is necessary to improve human reliability in order to gain a higher reliability of the total plant system taking an account of development of plant automation and improvement of machine reliability. Therefore, the role of the man-machine system will come to be important. Accordingly, the evaluation of the man-machine system design information is desired in order to solve the mismatch problem between plant information presented by the man-machine system and information required by the operator comprehensively. This paper discusses required functions and software framework for the man-machine interface design evaluation system. The man-machine interface design evaluation system has features to extract the potential matters which are inherent on the design information of man-machine system by simulating the operator behavior, the plant system and the man-machine system, considering the operator's cognitive performance and time dependency.

Dormancy effects on the reliability of nuclear thermal propulsion systems for long-term manned space missions

International Nuclear Information System (INIS)

Shooman, M.L.; Sforza, P.M.

1993-01-01

This paper explores the effects of dormancy on the reliability of a Nuclear Thermal Propulsion (NTP) system for long-term manned space missions, such as Mars exploration. Dormancy refers to the portion of space systems operation where the power and stress levels are significantly reduced from nominal values and the authors have identified dormancy as a significant effect. Three approaches are used to evaluate the relative importance of failure rates during dormant operation: use of failure rate models involving dormancy, power cycling and fully energized operation; study of data bases which include both dormant and energized failure rates; predictions based on an Arrhenius rate process formulation. The results of these approaches suggest that for a long term manned mission the dormancy, cycle, and energized failure rates will all be important. Reliability in the energized state normally receives utmost attention and care during design, however, unless equal attention is directed to dormancy, the mission reliability may be severely compromised

1986-12-01

A framework for Man-Machine System design in process industry projects is reported. It is based in the Guidelines for the Design of Man-Machine interfaces which have been generated in cooperation within the European Workshop for Industrial Computer Systems (EWICS). The application of EWICS Guidelines in industrial projects is demonstrated by six User Scenarios, which represent typical projects from different industries, e.g. electrical power generation and distribution, water control, pulp and paper production, oil and gas production. In all these projects Man-Machine System design has been conducted. It is recommended in the report that each Company develops its set of Man-Machine Systems Standard techniques/procedures. At present there are several techniques/procedures available which, for moderate costs, can be adapted to specific Company conditions. A menu of such Man-Machine System techniques/procedures is presented. Means of estimating the costs and benefits of Man-Machine System design are also described. (author)

First Diagnosis of Inflammatory Bowel Disease in a 91-Year-Old Man

Directory of Open Access Journals (Sweden)

2012-12-01

Full Text Available Inflammatory bowel diseases (IBDs are diseases that occur primarily in adolescence and early adult life. A second peak of IBD incidence occurs at the age of 50–80 years, while reports of first diagnosis after the age of 80 years are extremely rare. It is difficult to establish the true incidence of IBD in older patients due to problems of case definition, population, and particularly because it may be confused with other clinical conditions. A 91-year-old man was admitted to the Emergency Department with progressively worsening abdominal pain and 2–4 episodes of bloody diarrhea daily for the last month. Similar symptoms were not reported by the patient or his family during the past. Complete blood count and biochemical tests were normal, while stool examination showed erythrocytes and white blood cells. Pelvic CT showed inflammatory changes and loss of homogeneity in the perirectal fat together with considerable bowel wall thickening of both the rectum and sigmoid. Colonoscopy revealed edema, hyperemia and spontaneous friability, as well as microulcerations of the rectosigmoid mucosa. Tissue biopsies revealed histopathological lesions compatible with IBD. Finally the patient was treated with metronidazole, ciprofloxacin and mesalazine, with clear clinical improvement during the 5th day of treatment, and was finally discharged with almost normal stools. In conclusion, we report the case of first diagnosis of IBD in a 91-year-old man. The prevalence of IBD in patients aged >80 years is difficult to determine. Diagnostic tools are the same as for other age groups, but diagnosis may be difficult because there are a number of clinical conditions that may mimic IBD at this age. The treatment options are those used in younger patients, but special precautions should be taken.

In any complex system, the interesting problems occur at the interface of dissimilar subsystems. Control of the Mirror Fusion Test Facility (MFTF) begins with the US Congress, which controls the dollars, which control the people, who control the nine top-level minicomputers, which control the 65 microprocessors, which control the hardware that controls the physics experiment. There are many interesting boundaries across which control must pass, and the one that this paper addresses is the man-machine one. For the MFTF, the man-machine interface consists of a system of seven control consoles, each allowing one operator to communicate with one minicomputer. These consoles are arranged in a hierarchical manner, and both hardware and software were designed in a top-down fashion. This paper describes the requirements and the design of the console system as a whole, as well as the design and operation of the hardware and software of each console, and examines the possible form of a future man-machine interface

Self-regulation of eating and physical activity is lower in obese female college students as compared to their normal weight counterparts.

2017-06-01

Obesity is characterized, among other features, by overeating, reduced physical activity and an abnormal accumulation of body fat. These features are thought to result, at least in part, from the individual's inability to self-regulate their eating and physical activity behaviors (E&PaB). Self-regulation of the E&PaB is a three-step sequential process: self-observation, self-evaluation and self-reaction. However, it is yet unclear whether deficient self-regulation of E&PaB could predispose, facilitate and/or consolidate obesity. Unraveling this issue is fundamental in order to more precisely define the role of self-regulation of E&PaB in the management of obesity. This research was focused on the question of whether or not self-regulation of E&PaB is related to obesity in female undergraduate students. This population segment seems especially vulnerable to developing obesity since they undergo a significant shift of their E&PaB upon their university enrollment. To address this question, a cross-sectional study with 108 female undergraduate students with normal weight (n = 80) or obesity (n = 28) was performed, in which self-regulation of eating habits and physical activity was measured by two validated scales and a personal data questionnaire. Female undergraduate students displaying lower E&PaB self-reactions were consistently overweight or obese. In addition, a multivariate analysis identified high levels of self-reaction towards eating habits related to a minor presence of overweight issues or obesity. Self-regulation should be an essential component in the strategies for obesity prevention as an integral approach that must include orientation about healthy eating and physical activity behaviors. In addition, further studies on the effect of self-regulation in the treatment of the obesity are needed.

A Rich Man, Poor Man Story of S-Adenosylmethionine and Cobalamin Revisited.

Science.gov (United States)

Bridwell-Rabb, Jennifer; Grell, Tsehai A J; Drennan, Catherine L

2018-06-20

S-adenosylmethionine (AdoMet) has been referred to as both "a poor man's adenosylcobalamin (AdoCbl)" and "a rich man's AdoCbl," but today, with the ever-increasing number of functions attributed to each cofactor, both appear equally rich and surprising. The recent characterization of an organometallic species in an AdoMet radical enzyme suggests that the line that differentiates them in nature will be constantly challenged. Here, we compare and contrast AdoMet and cobalamin (Cbl) and consider why Cbl-dependent AdoMet radical enzymes require two cofactors that are so similar in their reactivity. We further carry out structural comparisons employing the recently determined crystal structure of oxetanocin-A biosynthetic enzyme OxsB, the first three-dimensional structural data on a Cbl-dependent AdoMet radical enzyme. We find that the structural motifs responsible for housing the AdoMet radical machinery are largely conserved, whereas the motifs responsible for binding additional cofactors are much more varied.

Tritium and plutonium content in the Italian diet and transfer to man

International Nuclear Information System (INIS)

Clemente, G.F.; Belloni, P.; Di Pietro, S.; Santori, G.

1979-01-01

Complete daily diets together with total daily excretion and blood samples have been collected for five days in a group of healthy subjects of both sexes, representative of the normal Italian population living in an environment unexposed to local releases of plutonium and tritium. The tritiated water content available by freeze drying ('loose water fraction') has been measured together with the additional tritium available by complete combustion ('organic bound fraction') in the various samples collected. The mean values of the daily dietary intake of tritium were 974 pCi for the organic bound fraction and 310 pCi for the loose water fraction. The metabolic balance in man was evaluated for both fractions by comparing the daily intake with the daily excretion and blood concentration data. The results indicate that to assess tritium exposure of the general population one must take into account the environmental sources and the metabolic behaviour in man of tritium in both the bound and loose compartments. The plutonium content has been measured in the diet samples only because of the very low concentration in excreta and blood. The yearly dietary intake of plutonium in Italy is of the order of 1.5 pCi, in good agreement with the data available in other countries. (author)

Primary cardiac lymphoma (PCL) respresents a very rare type of cardiac tumour. This report illustrates a case of PCL in an immunocompetent 58-year-old man presenting with atrial fibrillation and febrile syndrome. Comprehensive imaging [computer tomography (CT), cardiac magnetic resonance imaging (cMRI), 3-dimensional transesophageal echocardiography (3D-TEE)] identified a large right atrial tumour, leading to pericardial effusion. Isolated cardiac involvement was confirmed by positron emission tomography (PET)-CT. A diffuse large B-cell lymphoma (DLBCL) was diagnosed based on the results of a TEE-guided biopsy. A normalized PET scan (PETAL study) indicated complete remission following R-CHOP 14 immunochemotherapy. Thus, an interdisciplinary and multimodal approach avoided unnecessary cardiac surgery.

Facial dysmorphopsia: a notable variant of the "thin man" phenomenon?

Science.gov (United States)

Ganssauge, Martin; Papageorgiou, Eleni; Schiefer, Ulrich

2012-10-01

The aim of this work is to investigate the facial distortion (dysmorphopsia) experienced by patients with homonymous paracentral scotomas and to analyze the interrelationship with the previously described "thin man" phenomenon. Routine neuro-ophthalmological examination and brain MRI in three patients who suffered from small homonymous paracentral scotomas due to infarction or arteriovenous malformations of the occipital lobe. They all complained of distortion and shrinkage of their interlocutor's face contralateral to the brain lesion. The phenomenon appeared some seconds after steady fixation on the interlocutor's nose and was evident with both left and right homonymous scotomas. The patients did not notice a gap in the area corresponding to the scotoma and objects other than faces were perceived normally. Homonymous paracentral scotomas can lead to focal displacement of facial features towards the center of the field defect with resulting distortion of the face on the affected side. This so-called "dysmorphopsia" makes faces appear regionally narrower than they are in reality and may be induced even by visual field defects that remain undetected by conventional perimetry using 6° × 6° grids. Predilection for faces is probably associated with the superior location of scotomas or specific impairment of face processing abilities related to the lesion site. Facial dysmorphopsia is most probably associated with cortical "filling-in" and spatial distortion, and can hence be regarded as a special entity of the "thin man" phenomenon.

Regulation of heme metabolism in normal and sideroblastic bone marrow cells in culture

International Nuclear Information System (INIS)

Ibraham, N.G.; Lutton, J.D.; Hoffman, R.; Levere, R.D.

1985-01-01

Heme metabolism was examined in developing in vitro erythroid colonies (CFUE) and in bone marrow samples taken directly from four normal donors and four patients with sideroblastic anemia. Maximum activities of delta-aminolevulinic acid synthase (ALAS), ALA dehydratase (ALAD), and 14 C-ALA incorporation into heme were achieved in normal marrow CFUE after 8 days of culture, whereas heme oxygenase progressively decreased to low levels of activity during the same period. Assays on nucleated bone marrow cells taken directly from patients revealed that ALAS activity was considerably reduced in idiopathic sideroblastic anemia (IASA) and X-linked sideroblastic anemia (X-SA) bone marrow specimens, whereas the activity increased more than twofold (normal levels) when cells were assayed from 8-day CFUE. In all cases, ALAD activity appeared to be within normal levels. Measurement of heme synthesis revealed that normal levels of 14 C-ALA incorporation into heme were achieved in IASA cells but were reduced in X-SA cells. In marked contrast to levels in normal cells, heme oxygenase was found to be significantly elevated (two- to fourfold) in bone marrow cells taken directly from patients with IASA and X-SA. Results from this study demonstrate that IASA and X-SA bone marrow cells have disturbances in ALAS and heme metabolism, and that erythropoiesis (CFUE) can be restored to normal levels when cells are cultured in methylcellulose

Bents, D.; Patterson, M.J.; Berkopec, F.; Myers, I.; Presler, A.

1986-01-01

The high impulse of electric propulsion makes it an attractive option for manned interplanetary missions such as a manned mission to Mars. This option is, however, dependent on the availability of high energy sources for propulsive power in addition to that required for the manned interplanetary transit vehicle. Two power system technologies are presented: nuclear and solar. The ion thruster technology for the interplanetary transit vehicle is described for a typical mission. The power management and distribution system components required for such a mission must be further developed beyond today's technology status. High voltage-high current technology advancements must be achieved. These advancements are described. In addition, large amounts of waste heat must be rejected to the space environment by the thermal management system. Advanced concepts such as the liquid droplet radiator are discussed as possible candidates for the manned Mars mission. These thermal management technologies have great potential for significant weight reductions over the more conventional systems

Man and Cosmos from the Christian Theology perspective

Directory of Open Access Journals (Sweden)

Marin BUGIULESCU

2017-06-01

Full Text Available The purpose of this paper is to analyse the theological reflection on the relationship between man and cosmos. The origin of the world and man is connected to God; God is the Creator and consequently the Author of them both. Unlike dualistic materialistic thinking, according to the Christian conception the whole cosmos is created by God. In search for the cosmos an important chapter was granted for man, considered to be a synthesis of the world. Man, from the theological perspective, is the personal, rational, free, and speaking being that has – through the image of God according to which he has been created –, the tension after perfection. But it pertains exclusively to the relationship with Christ in the light of Whom he really knows himself, and by knowing himself he recognizes the infinite beauty of the Archetype. This is the existential-theological truth, which the content of this paper emphasizes, according to the Bible and patristic teaching.

MAN Nutzfahrzeuge AG (Munich, Federal Republic of Germany) always is eager to offer products for the respective markets whereby the products are interesting for the customer under economic criteria. Additionally, the products shall not lack in the travelling comfort under consideration of the legal emission borders. Thus, a AdBlue {sup registered} free technology for all MAN series was already offered before the legal introduction of EURO IV. This technology is based on an internal-motor solution with external, cooled AGR and a PM-Cat {sup registered} -filter. This solution is esteemed highly by our customers because apart from the well-known advantages in relation to a SCR technology there were no losses with the operating cost. With EURO V which is inserted in some countries MAN Nutzfahrzeuge AG returns to a long-term experience with SCR technology. The motivation for the development of a AdBlue {sup registered} free solution was the positive feedback of our customers on the basis of MAN EURO IV AGR/PM Cat technology. With the developed EURO V AGR solution, other EURO IV solutions in line with market conditions for the 'Emerging markets' can be derived with which a technology without exhaust post-treatment can be offered worldwide for our customers. This technology presents the basis for a platform concept EURO IV/V and EURO VI. In this concept, EURO IV can be presented without subsequent treatment of exhaust gases, EURO V in connection with an Oxicat and EURO VI with a SCRT system. Here, the vehicle/engine concept presents the most important components for the individual series in particular. By means of these components, the goal EURO V was achieved internal-motor without losses of operating cost and life span in relation to SCR technologies.

Cancer risk assessments and environmental regulation

International Nuclear Information System (INIS)

Scroggin, D.G.

1990-01-01

Governmental regulation of toxic substances, such as carcinogens and radiation, prompts both legal and scientific controversies. Industry, environmental activist groups, government regulators, and the general public are all concerned with the question of how environmental risk to public health is to be measured and what level of risk warrants government action under the environmental laws. Several recent events shed light on the fundamental scientific and legal problems inherent in such regulation, and these events may affect the direction of future developments. These events include implementation of generic Risk Assessment Guidelines by the US EPA, litigation challenging EPA's regulation of carcinogenic substances, new scientific understanding of the relative risks from human exposure to natural and man-made sources, and the continuing growth of toxic tort litigation in which victims of cancer seek large damages from industrial emitters of pollution

Measurement with nasal scintigraphy of nasal mucociliary clearance in normal man

International Nuclear Information System (INIS)

Murai, Sumiko

1989-01-01

Nasal mucociliary function was evaluated by nasal scintigraphy in normal subjects. A microdrop of HSA or saline labelled with 99m Tc was dripped into the middle part of each middle meatus in the nasal cavity and its clearance was observed by scinticamera. The accumulated concentration of RI was determined every 30 seconds for 10 minutes. The changes of accumulated concentration were studied, and a curve of decreasing RI-counts was obtained, with the 'clearance rate' defined as 100% for the count at the initial 30 seconds and 'half time' as the time when radioactivity was reduced to one half the initial count. Nasal resistance was measured by rhinomanometry with the oscillation method. In nonsmokers, 10μl of saline was cleared (78.0±10.4%) significantly faster than 10μl of HSA (59.9±24.6%), and there was no significant difference in the clearance between 10μl and 5μl of HSA (55.9±27.7%). In smakers, the mucociliary clearance of 10μl of HSA and saline was significantly lower than in nonsmokers. The clearance of 10μl of HSA reflects a pathological state much better than that of 5μl. In nonsmokers, there is a significant negative correlation between nasal resistance and clearance rate, suggesting that the more patent the nose, the faster the mucociliary clearance. When both nostrils were closed, the clearance rate was significantly depressed. When one nostril was closed, there was no significant effect on clearance. Nasal resistance was decreased by exercise with a bicycle ergometer. Nasal mucociliary clearance was slightly decreased after exercise but not significantly so. (J.P.N.)

Radiation and man. From radiology to radiation protection

International Nuclear Information System (INIS)

2005-04-01

Man first became aware of the invisible radiation surrounding him in 1895, when Wilhelm Roentgen showed that a photographic plate could be affected by an invisible radiation capable of passing through matter. He called this radiation 'X-rays' from X, the unknown. Doctors immediately saw the usefulness of this type of radiation and began to use it in medical research. This was the birth of radiology. 'Mankind has been exposed to radiation since his first appearance on Earth. We first became aware of this at the end of the 19. century'. However, it was not long before some of the doctors and radiologists treating their patients with X-rays began to fall ill. It began to be understood that exposure to high doses of radiation was dangerous and protective measures were necessary. From the 1920's onwards, international commissions were established to specify regulations for the use of radiation and for the radiological protection of personnel. (authors)

Objective: To determine lanthanide concentrations in dietary foods and main organs or tissues for Chinese adult man and to estimate their daily intakes by ingestion and organ or tissue burdens. Methods: Ten kinds of organ or tissue samples collected in autopsy from 21 supplemental subjects of 4 areas with different dietary types in China who died suddenly, and had been healthy and normal before death. The concentrations of 11 lanthanide in foods and 14 lanthanide in these organ or tissue samples, including those collected from 31 subjects in the past, were analyzed by using ICP-MS or INAA technique as well as necessary QC measures. With uses of the local diet composition and relevant organ or tissue weights for Chinese Reference Man, their daily intakes and organ or tissue burdens were estimated. Results: The concentrations of 14 lanthanide in 12 categories of foods and 10 kinds of organ or tissue samples, their dietary daily intakes and organ or tissue burdens for Chinese adult men were obtained. Conclusion: Besides updating the relevant data of La, Ce and Eu in 5 kinds of organ or tissue and diet, this research obtained data on concentrations of other 11 lanthanide in Chinese foods and 10 kinds of organ or tissue, their daily intakes and burdens for the first time in China. The results provide more systematic bases for developing the parameters of Chinese Reference Man than before. This study provides also comparative data for different kinds of lanthanide, foods, organs or tissues and also the background values of Chinese soil

1984-01-01

Improvement of the man-machine interface of nuclear power plants is an important contribution to the further enhancement of operational safety. In addition, recent advances in computer technology seem to offer the greatest opportunity to date for achieving improvement in the man-machine interface. The development of a computerized operator support system for BWRs has been undertaken since 1980 with the support of the Japanese Government. The conceptual design of this system is based on the role of the operators. The main functions are standby system management, disturbance analysis and post-trip operational guidance. The objective of the standby system management is to monitor the standby status of the engineered safety feature during normal operation to assure its proper functioning at the onset of emergency situations. The disturbance analysis system detects disturbances in the plant in their early stages and informs the plant operators about, for example, the cause of the disturbances, the plant status and possible propagations. Consequently, operators can take corrective actions to prevent unnecessary plant shutdown. The objective of the post trip operational guide is to support operators in diagnosis and corrective action after a plant trip. Its functions are to monitor the performance of the engineered safety feature, to identify the plant status and to guide the appropriate corrective action to achieve safe plant shutdown. The information from the computerized operator support system is supplied to operators through a colour CRT operator console. The authors have evaluated the performance of various new man-machine interfacing tools and proposed a new operator console design. A prototype system has been developed and verification/validation is proceeding with a BWR plant simulator. (author)

Man appeared on the planet about four million years ago, and by 1850 numbered about one billion Ten came Hydrocarbon man. World population has since increased six-fold. After the oil price shocks of the 1970s, people asked "when will production peak?". It is not easy to answer this question because of the very poor database. Reserves and the many different hydrocarbon categories are poorly defined, reporting practices are ambiguous, revisions are not backdated...

[Knowledge of Man Returns: Some Considerations on Spirituality and Resilience].

Science.gov (United States)

Kumakura, Nobuhiro

2015-01-01

Over the last decade,"spirituality" and "resilience" have jointly become a topic in psychiatry. The aim of this paper is to discuss the future of psychiatry suggested by this topic. It may be related to what Jaspers, K. called "Knowledge of Man (die Erkenntnis des Menschen)". Knowledge of man in psychiatry can be learned only through clinical experince: e. g., clinical observations and case studies. Modern academic psychiatry seems to be suffering a loss of knowledge of man, which returns periodically in clinical practice. Hence, I will call the re-discovery of the topic in psychiatry as "Return of Man". Since WW II, there have been three eras in which psychiatrists showed deep concern regarding knowledge of man. Firstly, psychopathology and psychotherapy widely developed, when the destructive impulses of mankind were revealed in the nuclear weapons of WW II. Secondly, in the 1970's, the reforms of psychiatric services and legal systems took place somewhat successfully, when social reforms were concerns of the younger generations. Lastly, over the last decade, the topic again returned as spirituality and resilience, when scientists seemed to be powerless in the aftermath of the West Japan Earthquake. Regarding the definition of health made by the WHO in 1946, I further discuss that "Return of Man" in psychiatry is the necessary dynamism between negative and positive health, or between disease control and health promotion. There is an underlying dynamism between "Knowledge of Man" and natural sciences, which is constantly changing. So long as any theory can exist only as a part of dynamism, the Return of Man may re-surface whenever clinical theories do not fit with clinical realities.

Regulation of pigmentation by substrate elasticity in normal human melanocytes and melanotic MNT1 human melanoma cells.

The elasticity of the cellular microenvironment is a key regulator of cellular physiology in many cell types. To investigate the effects of substrate stiffness on the pigmentation process, we cultured normal human melanocytes (NHM) and MNT1 melanoma cells on laminin-coated polydimethylsiloxane (PDMS) substrates of different stiffness. The dendricity of NHM and MNT1 cells was reduced as the substrate stiffness decreased, and the degree of melanosome transfer from NHM or MNT1 cells to normal human keratinocytes was decreased on softer substrates with the reduced dendricity. Gene and protein expressions of MITF, tyrosinase, TRP2, and gp100/PMEL17 exhibited a consistent decreasing trend with the decreasing stiffness. Because the stiffness sensing is mediated by focal adhesion complex through integrin receptors, we checked laminin specific integrin alpha 6 and p-FAK for MNT1 cells to observe that the substrate adhesion was weakened as the substrate stiffness decreased. Weaker adhesion on a softer substrate was accompanied by dynamic shape changes in MNT1 cells with higher speed and larger scattering. Dendritic MNT1 cells cultured on a stiffer substrate exhibited lower migration with smaller root mean squared displacement. These results demonstrate the possibility that skin pigmentation can be influenced by mechanical properties of the cellular microenvironment and can increase when the skin becomes stiff. © 2014 John Wiley & Sons A/S.

STOIAN Mihai Sebastian

2016-06-01

Full Text Available God made Himself a man for man to reach the likeness of God – this is the essential idea of the oikonomia of our salvation, dear to all the Church Fathers, from Saint Irenaeus to Saint Athanasius the Great and the essence of Christ, mystery and original and fundamental sacrament of our meeting with God and of our salvation, of all of us, in Christ, and of the acquisition by each man of the fruits of salvation and deification through Christ, in the Holy Spirit, in His Church. Christ’s mystery and sacrament begins by the Embodiment of the Father’s Logos. The Passions, the cross, the tomb and the resurrection are its continuation. And all these translate the mystery of the reason why God created everything and the very mystery of man - participating to the original mystery, namely Christ, and the Church, as sacrament. Therefore, Christ is the Mystery and the sacrament by excellence - original and general -, spring and content of all the mysteries and sacraments, condition and explanation of all these.

Small reactor power systems for manned planetary surface bases

Energy Technology Data Exchange (ETDEWEB)

Bloomfield, H.S.

1987-12-01

A preliminary feasibility study of the potential application of small nuclear reactor space power systems to manned planetary surface base missions was conducted. The purpose of the study was to identify and assess the technology, performance, and safety issues associated with integration of reactor power systems with an evolutionary manned planetary surface exploration scenario. The requirements and characteristics of a variety of human-rated modular reactor power system configurations selected for a range of power levels from 25 kWe to hundreds of kilowatts is described. Trade-off analyses for reactor power systems utilizing both man-made and indigenous shielding materials are provided to examine performance, installation and operational safety feasibility issues. The results of this study have confirmed the preliminary feasibility of a wide variety of small reactor power plant configurations for growth oriented manned planetary surface exploration missions. The capability for power level growth with increasing manned presence, while maintaining safe radiation levels, was favorably assessed for nominal 25 to 100 kWe modular configurations. No feasibility limitations or technical barriers were identified and the use of both distance and indigenous planetary soil material for human rated radiation shielding were shown to be viable and attractive options.

2013-12-01

Full Text Available This article tries to elucidate A.M Iqbal’s vision on the concept of perfectman. Its significance is at the point that Man can transform both his being andhis surroundings according to his own desires and aspirations. He actually makesimprovements upon what is created by God. God created night, he inventedthe lamp; God created clay, and from it he made the cup; God created deserts,mountains, forests, orchards, gardens, and groves. He makes glass out of stoneand turns poison into an antidote. God created the world, but he made it morebeautiful.Iqbal’s reasoning amply justifies belief in the ascendancy of man overthe universe and his predicted perfection. The perfect man is the ultimate endof the revolutionary process, and he is developed out of the present man, justas the full moon is developed from the crescent.

Combinatorial regulation of tissue specification by GATA and FOG factors

Science.gov (United States)

Chlon, Timothy M.; Crispino, John D.

2012-01-01

The development of complex organisms requires the formation of diverse cell types from common stem and progenitor cells. GATA family transcriptional regulators and their dedicated co-factors, termed Friend of GATA (FOG) proteins, control cell fate and differentiation in multiple tissue types from Drosophila to man. FOGs can both facilitate and antagonize GATA factor transcriptional regulation depending on the factor, cell, and even the specific gene target. In this review, we highlight recent studies that have elucidated mechanisms by which FOGs regulate GATA factor function and discuss how these factors use these diverse modes of gene regulation to control cell lineage specification throughout metazoans.

Oedipus king: preparing man for the polis

Directory of Open Access Journals (Sweden)

José Joaquim Pereira Melo

2013-09-01

Full Text Available Having Sophoclean play Oedipus King as a frame of reference, the purpose of this paper is to discuss the educative proposal conceived to the Greek Man as preparation for life in the polis. Although not intentionally, Sophocles pointed out an ideal of Man which, in his perspective, would fulfill Greek societal demands of that time. Such society was divided between myth and rationality and, as a result, Man found Himself in conflict and lacking direction for His life. Given that, Oedipus’ character represented the ideal behavior of that society, and it also made it possible for citizens to reflect and to discuss social, economic and political transformations taking place at that period. Thus Sophocles came up with a hero who was an educational model and a citizen’s as well. Furthermore, such hero differed from that one of the archaic Greek thought.

This research topic was first established in China by Professor Shengzhao Long in 1981, with direct support from one of the greatest modern Chinese scientists, Xuesen Qian. In a letter to Shengzhao Long from October 22nd, 1993, Xuesen Qian wrote: “You have created a very important modern science subject and technology in China!” MMESE primarily focuses on the relationship between Man, Machine and Environment, studying the optimum combination of man-machine-environment systems. In this system, “Man” refers to working people as the subject in the workplace (e.g. operators, decision-makers); “Machine” is the general name for any object controlled by Man (including tools, machinery, computers, systems and technologies), and “Environment” describes the specific working conditions under which Man and Machine interact (e.g. temperature, noise, vibration, hazardous gases etc.). The three goals of optimization are to ensure "Safety, High efficiency and Economy" of man-machine-environment systems. These...

Fusion and normalization to enhance anomaly detection

This study examines normalizing the imagery and the optimization metrics to enhance anomaly and change detection, respectively. The RX algorithm, the standard anomaly detector for hyperspectral imagery, more successfully extracts bright rather than dark man-made objects when applied to visible hyperspectral imagery. However, normalizing the imagery prior to applying the anomaly detector can help detect some of the problematic dark objects, but can also miss some bright objects. This study jointly fuses images of RX applied to normalized and unnormalized imagery and has a single decision surface. The technique was tested using imagery of commercial vehicles in urban environment gathered by a hyperspectral visible/near IR sensor mounted in an airborne platform. Combining detections first requires converting the detector output to a target probability. The observed anomaly detections were fitted with a linear combination of chi square distributions and these weights were used to help compute the target probability. Receiver Operator Characteristic (ROC) quantitatively assessed the target detection performance. The target detection performance is highly variable depending on the relative number of candidate bright and dark targets and false alarms and controlled in this study by using vegetation and street line masks. The joint Boolean OR and AND operations also generate variable performance depending on the scene. The joint SUM operation provides a reasonable compromise between OR and AND operations and has good target detection performance. In addition, new transforms based on normalizing correlation coefficient and least squares generate new transforms related to canonical correlation analysis (CCA) and a normalized image regression (NIR). Transforms based on CCA and NIR performed better than the standard approaches. Only RX detection of the unnormalized of the difference imagery in change detection provides adequate change detection performance.

Physical characteristics of the Japanese in relation to reference man

Quantitative description of physical and other characteristics of the human body provides basic data for the estimation of radiation risk and the establishment of dose equivalent in line with the International Commission on Radiological Protection recommendations. ICRP Reference Man is based essentially on data reported on populations in rather limited areas in the world although Committee 2 of ICRP concedes that ''it is neither feasible nor necessary to specify Reference Man as representative of a well-defined population group''. ICRP Reference Man is not necessarily based on the most recent available data. In order to be more realistic and quantitative in dose equivalent estimation in Japan, it is necessary to consider populations which are largely different from those of European and North American countries in physical dimensions and other aspects. Therefore, standard or reference values of mass and size of organs, body and organ content and metabolic parameters of some elements have been studied. These are compared with the values of ICRP Reference Man authorized up to now, with the intention of establishing ''Reference Japanese Man'' and contributing to the improvement of models of man used in radiation protection. Dose equivalent commitment and annual limit of intake have been calculated using the obtained data for the general population in Japan,for some nuclides. (H.K.)

Consideration is being given to the role of ''human factors'' and the ways of improving the man-machine interaction in NPP control and safety systems (CSS). Simulators and tAaining equipment on the basis of dynamic power unit models used for training and improving skill of NPP operatoAs, as well as for mastering collective actions of personnel under accidental conditions are considered in detail. The most perfect program complexes for fast NPP diagnostics and theiA pealization in the Federal Republic of Germany, Japan, Canada, the USA and other countries are described. A special attention is paid to the means and methods of videoterminal dialogue operator interaction with an object both in normal and extreme situations. It is noted that the problems of the man-machine interaction have become the subject of study only in the end of 70s after analyzing the causes of the Three-Mile-Island accident (USA). Publications dealing with the development of perspective control rooms for NPP were analyzed. It was concluded that radical changes both in equipment and principles of organizing the personnel activity will take place in the nearest future. They will be based on the progress in creating dialogue means and computers of the fourth and fifth generations as well as on engineering and psychological and technical aspects of designing

In the present work, we optimised and evaluated a qPCR system integrating 6-FAM (6-carboxyfluorescein)-labelled TaqMan probes and melting analysis using the SYTO 82 (S82) DNA binding dye in a single reaction. We investigated the influence of the S82 on various TaqMan and melting analysis parameters and defined its optimal concentration. In the next step, the method was evaluated in 36 different TaqMan assays with a total of 729 paired reactions using various DNA and RNA templates, including field specimens. In addition, the melting profiles of interest were correlated with the electrophoretic patterns. We proved that the S82 is fully compatible with the FAM-TaqMan system. Further, the advantages of this approach in routine diagnostic TaqMan qPCR were illustrated with practical examples. These included solving problems with flat or other atypical amplification curves or even false negativity as a result of probe binding failure. Our data clearly show that the integration of the TaqMan qPCR and melting analysis into a single assay provides an additional control option as well as the opportunity to perform more complex analyses, get more data from the reactions, and obtain analysis results with higher confidence.

Effect of Variable Manning Coefficients on Tsunami Inundation

Science.gov (United States)

Barberopoulou, A.; Rees, D.

2017-12-01

Numerical simulations are commonly used to help estimate tsunami hazard, improve evacuation plans, issue or cancel tsunami warnings, inform forecasting and hazard assessments and have therefore become an integral part of hazard mitigation among the tsunami community. Many numerical codes exist for simulating tsunamis, most of which have undergone extensive benchmarking and testing. Tsunami hazard or risk assessments employ these codes following a deterministic or probabilistic approach. Depending on the scope these studies may or may not consider uncertainty in the numerical simulations, the effects of tides, variable friction or estimate financial losses, none of which are necessarily trivial. Distributed manning coefficients, the roughness coefficients used in hydraulic modeling, are commonly used in simulating both riverine and pluvial flood events however, their use in tsunami hazard assessments is primarily part of limited scope studies and for the most part, not a standard practice. For this work, we investigate variations in manning coefficients and their effects on tsunami inundation extent, pattern and financial loss. To assign manning coefficients we use land use maps that come from the New Zealand Land Cover Database (LCDB) and more recent data from the Ministry of the Environment. More than 40 classes covering different types of land use are combined into major classes such as cropland, grassland and wetland representing common types of land use in New Zealand, each of which is assigned a unique manning coefficient. By utilizing different data sources for variable manning coefficients, we examine the impact of data sources and classification methodology on the accuracy of model outputs.

Conference on Manned Systems Design : New Methods and Equipment

This volume contains the proceedings of a conference held in Freiburg, West Germany, September 22-25, 1980, entitled "Manned Systems Design, New Methods and Equipment". The conference was sponsored by the Special Programme Panel on Human Factors of the Scientific Affairs Division of NATO, and supported by Panel VIII, AC/243, on "Human and Biomedical Sciences". Their sponsorship and support are gratefully acknowledged. The contributions in the book are grouped according to the main themes of the conference with special emphasis on analytical approaches, measurement of performance, and simulator design and evaluat ion. The design of manned systems covers many and highly diversified areas. Therefore, a conference under the general title of "Manned Systems Design" is rather ambitious in itself. However, scientists and engineers engaged in the design of manned systems very often are confronted with problems that can be solved only by having several disciplines working together. So it was felt that knowledge about ...

It is shown that the specific 137 Cs content (as related to the potassium content in man) continuously decreased from 1965 through 1974. After a slight increase in 1975, possibly caused by a Chinese atmospheric nuclear test in June 1974, the 137 Cs content again decreased in the following years. (author)

Combinatorial interactions among transcription factors are critical to directing tissue-specific gene expression. To build a global atlas of these combinations, we have screened for physical interactions among the majority of human and mouse DNA-binding transcription factors (TFs). The complete networks contain 762 human and 877 mouse interactions. Analysis of the networks reveals that highly connected TFs are broadly expressed across tissues, and that roughly half of the measured interactions are conserved between mouse and human. The data highlight the importance of TF combinations for determining cell fate, and they lead to the identification of a SMAD3/FLI1 complex expressed during development of immunity. The availability of large TF combinatorial networks in both human and mouse will provide many opportunities to study gene regulation, tissue differentiation, and mammalian evolution.

Man-midwifery history: 1730-1930.

Shelton, D C

This paper seeks to determine whether the man-midwives William Smellie and William Hunter deserve continuing approbation as 'Founding Fathers' of the obstetrics profession. Scrutiny of their careers reveals their involvement in murders for dissection. In addition, the man-midwifery initiative of delivery in lying-in hospitals resulted in around 1 million more deaths in Britain and Ireland between 1730 and 1930, than would have occurred had home-births remained as the norm. While some may still credit Smellie and Hunter with obstetric discoveries, their knowledge was obtained by murder-for-dissection. That indictment, together with the lying-in hospital legacy, far outweighs their discoveries. The paper invites further constructive discussion and debate, but concludes the accolade of Founding Fathers is undeserved. Any continuing endorsement of Smellie and Hunter effectively demeans the high ethical standards and reputation of current obstetric professionals.

Loss of Kindlin 1 (Kin1) results in the skin blistering disorder Kindler Syndrome (KS), whose symptoms also include skin atrophy and reduced keratinocyte proliferation. Kin1 binds to integrins to modulate their activation and more recently it has been shown to regulate mitotic spindles and cell survival in a Plk1-dependent manner. Here we report that short-term Kin1 deletion in mouse skin results in impaired mitosis, which is associated with reduced acetylated tubulin (ac-tub) levels and cell proliferation. In cells, impaired mitosis and reduced ac-tub levels are also accompanied by reduced microtubule stability, all of which are rescued by HDAC6 inhibition. The ability of Kin1 to regulate HDAC6-dependent cellular ac-tub levels is dependent on its phosphorylation by Plk1. Taken together, these data define a novel role for Kin1 in microtubule acetylation and stability and offer a mechanistic insight into how certain KS phenotypes, such as skin atrophy and reduced cell proliferation, arise. © The Author (2016).

DOTA-Substance-P (SP) and DOTA-minigastrin (His2-MG) labeled with 177 Lu could be used in peptide receptor radionuclide therapy (PRRT) for treatment of various tumour species. Biodistribution studies of both radiopharmaceuticals in normal mice were performed at different times. Absorbed doses in mouse organs were estimated and extrapolated to humans. Dosimetric calculations showed that kidneys received the highest dose, for both radiopharmaceuticals. The Maximum Tolerated Activity (MTA) of 177 Lu-DOTA-SP that can be administered without kidney toxicity are 414 and 422 MBq/kg for the standard adult man and woman, respectively. In the same way, the MTA of 177 Lu-DOTA-His2-MG are 488 and 518 MBq/kg for the standard adult man and woman, respectively. (authors)

The discussion of cultural and sociological consequences of computer evolution is hindered by human prejudice. For example the sentence 'a computer is at best as intelligent as its programmer' veils actual developments. Theoretical limits of computer intelligence are the limits of intelligence in general. Modern computer systems replace not only human labour, but also human decision making and thereby human responsibility. The historical situation is unique. Human head-work is being automated and man is loosing function. (orig.) [de

The man in the business of nuclear security. Most important link - Yes or no?

How to attract and prepare a man to be a strong link in the system of nuclear safety and security and contribute to their development and social awareness? Why is this difficult task related to securing the funds from which the harmonization of regulations, technical equipment, equipment maintenance and systems will be financed? Do you sometimes make a mistake by dealing with individual partner organizations in attempts to establish an effective system of nuclear safety and security? The user has to be addressed in direct communication in to help him be faster, more efficient and to have the overall process less costly. This is fine when the inefficiency of some partner organizations only results of its internal organizational factors (management, size, strategy development, equipment, organizational culture). But what if this is not the case and if you neglect external factors (economic system in the country, institutional conditions, level of technology) and, finally, the culture of society as a critical factor? What are the problems then that arise in the system of nuclear safety and security in the country? Is a man again in the center of those problems and how can he deal with them? (author)

NASA currently is working with industry and the Federal Aviation Administration (FAA) to establish future requirements for Unmanned Aircraft Systems (UAS) flying in the National Airspace System (NAS). To work these issues NASA has established a multi-center "UAS Integration in the NAS" project. In order to establish Ground Control Station requirements for UAS, the perspective of each of the major players in NAS operations was desired. Three on-line surveys were administered that focused on Air Traffic Controllers (ATC), pilots of manned aircraft, and pilots of UAS. Follow-up telephone interviews were conducted with some survey respondents. The survey questions addressed UAS control, navigation, and communications from the perspective of small and large unmanned aircraft. Questions also addressed issues of UAS equipage, especially with regard to sense and avoid capabilities. From the civilian ATC and military ATC perspectives, of particular interest are how mixed operations (manned / UAS) have worked in the past and the role of aircraft equipage. Knowledge gained from this information is expected to assist the NASA UAS Integration in the NAS project in directing research foci thus assisting the FAA in the development of rules, regulations, and policies related to UAS in the NAS.

Evolution of man in the light of molecular genetics: a review. Part I. Our evolutionary history and genomics.

2007-07-01

The discovery in the mid 1970s of efficient methods of DNA sequencing and their subsequent development into more and more rapid procedures followed by sequencing the genomes of many species, including man in 2001, revolutionised the whole of biology. Remarkably, new light could be cast on the evolutionary relations of different species, and the tempo and mode of evolution within a given species, notably man, could quantitatively be illuminated including ongoing evolution possibly involving also the size of the brains. This review is a short summary of the results of the molecular genetic investigations of human evolution including the time and place of the formation of our species, our evolutionary relation to the closest living species relatives as well as extinct forms of the genus Homo. The nature and amount of genetic polymorphism in man is also considered with special emphasis on the causes of this variation, and the role of natural selection in human evolution. A consensus about the mosaic nature of our genome and the rather dynamic structure of our ancestral population is gradually emerging. The modern gene pool has most likely been contributed to several different ancestral demes either before or after the emergence of the anatomically modern human phenotype in the extent that even the nature of the evolutionary lineage leading to the anatomically modern man as a distinct biological species is disputable. Regulation of the function of genes, as well as the evolution of brains will be dealt with in the second part of this review.

Several forms of experimental evidence gathered in the last 37 years have unequivocally established that the medulla oblongata harbors the main neural circuits responsible for generating the vasomotor tone and regulating arterial blood pressure. Our current understanding of this circuitry derives mainly from the studies of Pedro Guertzenstein, a former student who became Professor of Physiology at UNIFESP later, and his colleagues. In this review, we have summarized the main findings as well as our collaboration to a further understanding of the ventrolateral medulla and the control of arterial blood pressure under normal and pathological conditions.

Some similarities of radium and plutonium toxicity in the beagle and man

International Nuclear Information System (INIS)

Taylor, G.N.; Jee, W.S.S.; Mays, C.W.

1976-01-01

The value of many toxicity studies, involving various experimental animals, is contingent on how reliably the data can be related to man. An equation has been proposed for extrapolating the Pu syndrome from dog studies to man. It employs the extensive human radium experience and a plutonium-radium toxicity ratio in the dog. The validity of this method is contingent on similar target tissues for both Pu and Ra and approximately equal RBE's for Pu relative to Ra in both man and the dog. Thus, although the radiosensitivity might be significantly different, the endpoints within a given tissue in man and the animal model must necessarily be comparative. The degree of parallelism in the radium-induced syndromes of man and the beagle are examined in order to assess the practicability of estimating Pu risk in man through use of a Pu-Ra toxicity ratio in the beagles

"I Am Chelsea Manning": Comparison of Gendered Representation of Private Manning in U.S. and International News Media.

On August 22, 2013, Bradley Manning released a statement requesting to be referred to as female. In the following days, the news media discussed whether language should shift toward a female representation. Using quantitative content analysis and qualitative contextual analysis, this study analyzed whether U.S. and international newspapers (N = 197) acknowledged Manning's request to be referred to as "Chelsea" in the two weeks after the statement. Results suggest that the mainstream press was hesitant in shifting toward a female representation. A comparison of international and U.S. newspapers suggests that the U.S. press lagged behind international coverage using a female depiction.

An immunocompromised man presented with an inflammatory eyelid lesion. Biopsy was performed; histopathology and special staining confirmed a diagnosis of bacillary angiomatosis. The man was treated with oral erythromycin, and the lesion resolved. The etiologic agents of bacillary angiomatosis are Bartonella henselae and Bartonella quintana, Gram-negative coccobacilli. The organisms stain positively with the Warthin-Starry silver stain. Lesions can be cutaneous or visceral and have been commonly described in immunocompromised patients. Histopathologic examination of lesions reveals angiogenesis and cellular proliferation. Bacillary angiomatosis can be treated with oral antibiotics.

This paper gives an overview of the current state of the art in man-machine system interaction studies, focusing on the problems derived from highly automated working environments and the role of humans in the control loop. In particular, it is argued that there is a need for sound approaches to the design and analysis of man-machine interaction (MMI), which stem from the contribution of three expertises in interfacing domains, namely engineering, computer science and psychology: engineering for understanding and modelling plants and their material and energy conservation principles; psychology for understanding and modelling humans an their cognitive behaviours; computer science for converting models in sound simulations running in appropriate computer architectures.

Pathways to man

International Nuclear Information System (INIS)

Harley, J.H.

1980-01-01

The study of radionuclide pathways leading to man generally has the goal of allowing us to predict human exposure from measurements of the radionuclide concentration in some segment of the environment. This modelling process provides a valuable tool in both the regulatory and health protection fields. However, most of the models in the regulatory field and in the health physics profession were designed to maximize exposure estimates. It is preferable to have scientifically defensible estimates and to add suitable safety factors at the end. Thus we are still faced with the development and validation of suitable models for many of the radionuclides of interest. The most useful models will include means of assessing variability and uncertainty. In this case variability might be considered as the differences in behavior due to age, sex or other factors in animals or man and those differences among plant species or animal species that determine their uptake factors. The uncertainty, on the other hand, would be the estimate of possible error in the experimental measurements. Model parameters would always have some variability even for site-specific cases and broad averages for population groups would have to include a factor expressing the possible variabilty and uncertainity. Thus any exposure calculation would have to be expressed with some range and valid assessments of this range are required

A study has been made to obtain/collect sex specific data on human physical parameters of Bangladeshi population of 9 age groups covering all ages for establishing a Bangladeshi/Asian Reference Man for radiation protection purposes. Eleven physical parameters were considered for measurement, namely height and weight of the total body, sitting height, chest girth, combined height of head and neck, head circumference, head width, neck circumference, length of arm, circumference of arm and length of leg. Significant variation in values of respective parameters was observed in most cases between male and female populations of the same age group. The measured values were compared with those of ICRP Reference Man of Caucasian origin. It is observed that the values of physical parameters of Caucasian Reference Man are systematically and probably significantly higher than those of the corresponding Bangladeshi Reference Man. The weights of male and female population of Caucasian Reference Man are approximately 20-30% higher than those of the corresponding Bangladeshi man. Since the organs of the body are roughly proportional to the body weight, the respective masses of the organs would be different by the same ratio factor and could be used for internal dosimetry purposes.

A 73-year-old man presented with bilateral leg pain and swelling, and no history of trauma or bleeding disorders. Clinical examination, biochemistry and magnetic resonance imaging of the thighs were suggestive of muscle haematomas. These progressed significantly during the admission, requiring blood transfusion. Normal vascular anatomy on computed tomography, renal and liver function, and absence of infection made a bleeding diathesis more likely. This may be caused by coagulation defects, platelet disorders and vascular fragility. An undetectable serum ascorbic acid level confirmed the clinical suspicion of scurvy, and administration of vitamin C resulted in rapid improvement. Our case provides a structured approach to the diagnosis of bleeding disorders and scurvy, a treatable and potentially fatal disease which is often forgotten. © Royal College of Physicians 2018.

Regulation mechanisms of pituitary-thyroid axis in normal subjects and patients with Graves' disease

Takagi, Shinko; Yamauchi, Kazuyuki; Mori, Yuichi

1986-01-01

The regulatory mechanism of the pituitary-thyroid axis in normal subjects and patients with Graves' disease was investigated using a highly sensitive TSH assay based on the immunoradiometric assay. All of the normal subjects had detectable TSH values within the range 0.35 to 6.0 μU/ml. No negative correlations between TSH and free thyroid hormones existed in normal subjects. Patients with thyroid carcinoma who seemed to have normal pituitary-thyroid function showed a rapid increase of TSH after total thyroidectomy. On the other hand, while untreated patients with Graves' disease all had undetectable TSH values, these patients took 1 to 3.5 months longer to normalize their TSH values than to normalize free thyroid hormones on antithyroid drug therapy. During the recovery phase by the treatment with decrease of antithyroid drug or supplement of T 4 from iatrogenic hypothyroid state after treatment for Graves' disease and thyroid carcinoma, normalization of TSH levels was delayed than that of free thyroid hormones. Patients with Graves' disease in remission showed an extremely positive correlation between basal and peak TSH levels in TRH test, and a negative correlation between basal TSH and FT 4 . In conclusion, an individual patient may have a different set point concerning the regulatory mechanism of the pituitary-thyroid axis, and the persistence of the hyperthyroid state would seem to have caused some reversible dysfunction of the pituitary gland.

TaxMan: a taxonomic database manager

Directory of Open Access Journals (Sweden)

Blaxter Mark

2006-12-01

Full Text Available Abstract Background Phylogenetic analysis of large, multiple-gene datasets, assembled from public sequence databases, is rapidly becoming a popular way to approach difficult phylogenetic problems. Supermatrices (concatenated multiple sequence alignments of multiple genes can yield more phylogenetic signal than individual genes. However, manually assembling such datasets for a large taxonomic group is time-consuming and error-prone. Additionally, sequence curation, alignment and assessment of the results of phylogenetic analysis are made particularly difficult by the potential for a given gene in a given species to be unrepresented, or to be represented by multiple or partial sequences. We have developed a software package, TaxMan, that largely automates the processes of sequence acquisition, consensus building, alignment and taxon selection to facilitate this type of phylogenetic study. Results TaxMan uses freely available tools to allow rapid assembly, storage and analysis of large, aligned DNA and protein sequence datasets for user-defined sets of species and genes. The user provides GenBank format files and a list of gene names and synonyms for the loci to analyse. Sequences are extracted from the GenBank files on the basis of annotation and sequence similarity. Consensus sequences are built automatically. Alignment is carried out (where possible, at the protein level and aligned sequences are stored in a database. TaxMan can automatically determine the best subset of taxa to examine phylogeny at a given taxonomic level. By using the stored aligned sequences, large concatenated multiple sequence alignments can be generated rapidly for a subset and output in analysis-ready file formats. Trees resulting from phylogenetic analysis can be stored and compared with a reference taxonomy. Conclusion TaxMan allows rapid automated assembly of a multigene datasets of aligned sequences for large taxonomic groups. By extracting sequences on the basis of

Pathways of evolution for man and machine

Mclaughlin, W. I.

1983-01-01

A simplified model of the future is introduced in order to examine the relations between man, machine, and extraterrestrial intelligence. The observed lack of extraterrestrials on earth is used as a boundary condition for the model. Two exobiological conclusions are obtained: (1) advanced extraterrestrials exist but are difficult to observe or to distinguish from natural phenomena, (2) lower level, man-like extraterrestrials, which are potentially observable, are rare in the Universe because they are rapidly replaced in the evolutinary sequence by the intelligent machines which they create. The decline of man is inferred and may take place as soon as 100 years from now or as long as 100,000 years from the present time. Thus, we are a short-lived species, having a life expectancy of only a million years. A note is appended on the rationale and methods of the search for extraterrestrial intelligence in light of the above calculations. The Tau Ceti and Epsilon Eridani systems present favourable opportunities for a radio-search experiment in 1987 and 1988, respectively.

A few of the physiological characteristics such as the daily consumption of drinking water, sweat rate were however, found to be higher, and the minute volume was similar for Reference Indian, in comparison to the ICRP Reference Man. The details of various human characteristics representative of the Indian population are reported in this paper. (author). 43 refs., 25 tabs., 6 figs

Space nuclear reactor shields for manned and unmanned applications

International Nuclear Information System (INIS)

McKissock, B.I.; Bloomfield, H.S.

1990-01-01

Missions which use nuclear reactor power systems require radiation shielding of payload and/or crew areas to predetermined dose rates. Since shielding can become a significant fraction of the total mass of the system, it is of interest to show the effect of various parameters on shield thickness and mass for manned and unmanned applications. Algorithms were developed to give the thicknesses needed if reactor thermal power, separation distances and dose rates are given as input. The thickness algorithms were combined with models for four different shield geometries to allow tradeoff studies of shield volume and mass for a variety of manned and unmanned missions. The shield design tradeoffs presented in this study include the effects of: higher allowable dose rates; radiation hardened electronics; shorter crew exposure times; shield geometry; distance of the payload and/or crew from the reactor; and changes in the size of the shielded area. Specific NASA missions that were considered in this study include unmanned outer planetary exploration, manned advanced/evolutionary space station and advanced manned lunar base. (author)

Synaptogenesis in visual cortex of normal and preterm monkeys: evidence for intrinsic regulation of synaptic overproduction.

Science.gov (United States)

Bourgeois, J P; Jastreboff, P J; Rakic, P

1989-01-01

We used quantitative electron microscopy to determine the effect of precocious visual experience on the time course, magnitude, and pattern of perinatal synaptic overproduction in the primary visual cortex of the rhesus monkey. Fetuses were delivered by caesarean section 3 weeks before term, exposed to normal light intensity and day/night cycles, and killed within the first postnatal month, together with age-matched controls that were delivered at term. We found that premature visual stimulation does not affect the rate of synaptic accretion and overproduction. Both of these processes proceed in relation to the time of conception rather than to the time of delivery. In contrast, the size, type, and laminar distribution of synapses were significantly different between preterm and control infants. The changes and differences in these parameters correlate with the duration of visual stimulation and become less pronounced with age. If visual experience in infancy influences the maturation of the visual cortex, it must do so predominantly by strengthening, modifying, and/or eliminating synapses that have already been formed, rather than by regulating the rate of synapse production.

[Albert Schweitzer. The man as a symbol].

Science.gov (United States)

Urdaneta-Carruyo, Eliexer

2007-01-01

Albert Schweitzer, the great missionary physician from the XXth century, had a versatile personality that integrated multiple talents, leading to the slightly frequent conjunction of the thinker with the man of action, and the humanist with the scientist and the artist. He studied all these disciplines in a brilliant manner: Philosophy, Theology, Music and Medicine; he was also a great scholar of Bach's work, Jesus Christ and the civilization history. In his maturity, this great man renounced to the fame and glory gained as intellectual and musician, to dedicate his life as a physician for the forgotten African natives. His deeply religious spirit allowed him to penetrate into the most recondite of the human soul; in his personality, he expressed in its entire dimension the eternally unsatisfied desire of the solitary man, against the immensity of the universe. His philosophy, based on the respect for life, was realized throughout the practice of the medical profession. His noble character and personality was based on the man as symbol, since it was not so much what he did helping people but what people could do to others due to him. His singular example represented a moral force in the world, superior to millions of men armed for a war. In 1953, he received the Nobel Peace Prize for his philanthropic work in Africa during more that fifty years, and for his deep love to the living beings. He was transformed in a perennial legend as the Lambaréné doctor.

To design a new TaqMan® MGB probe for improving the specificity of Streptococcus mutans's detection. We extracted six DNA samples from different streptococcal strains for PCR reaction. Conventional nested PCR and TaqMan® MGB real-time PCR were applied independently. The first round of nested PCR was carried out with the bacterial universal primers, while a second PCR was conducted by using primers specific for the 16S rRNA gene of Streptococcus mutans. The TaqMan® MGB probe for Streptococcus mutans was designed from sequence analyses, and the primers were the same as nested PCR. Streptococcus mutans DNA with 2.5 mg/L was sequentially diluted at 5-fold intervals to 0.16 μg/L. Standard DNA samples were used to generate standard curves by TaqMan® MGB real-time PCR. In the nested PCR, the primers specific for Streptococcus mutans also detected Streptococcus gordonii with visible band of 282 bp, giving false-positive results. In the TaqMan® MGB real-time PCR reaction, only Streptococcus mutans was detected. The detection limitation of TaqMan® MGB real-time PCR for Streptococcus mutans 16S rRNA gene was 20 μg/L. We designed a new TaqMan® MGB probe, and successfully set up a PCR based method for detecting oral Streptococcus mutans. TaqMan® MGB real-time PCR is a both specific and sensitive bacterial detection method.

Genetically modified carnation (Dianthus caryophyllus L.) Moonshade was approved for planting and commercialization in several countries from 2004. Developing methods for analyzing Moonshade is necessary for implementing genetically modified organism labeling regulations. In this study, the 5'-transgene integration sequence was isolated using thermal asymmetric interlaced (TAIL)-PCR. Based upon the 5'-transgene integration sequence, conventional and TaqMan real-time PCR assays were established. The relative limit of detection for the conventional PCR assay was 0.05 % for Moonshade using 100 ng total carnation genomic DNA, corresponding to approximately 79 copies of the carnation haploid genome, and the limits of detection and quantification of the TaqMan real-time PCR assay were estimated to be 51 and 254 copies of haploid carnation genomic DNA, respectively. These results are useful for identifying and quantifying Moonshade and its derivatives.

[Man's place and anthropology in bioethics].

Science.gov (United States)

Tomar Romero, Francisca

2013-01-01

From the analysis of its epistemological status, the article focuses on the philosophical fundament of bioethics, stressing the need for an authentic anthropology as a reference or starting point. Being an applied ethics, the first fundament of bioethics is in ethics. It shows how only personalistic ethics, which takes as reference the nature or essence of man, can offer objective and universal criteria. Philosophical anthropology studies man as a whole, in an integral manner, from the perspective of its nature or fundamental aspects of his being. It analyzes the distinction and relationship between the philosophical anthropology and the positive anthropologies, as well as with the physical, human and social sciences. Finally, it reflects on the current anthropological crisis and its ethical consequences.

Recent developments in man-machine systems

Johannsen, G.

1987-01-01

The field of man-machine systems is introduced with its subareas and a short outline of its history of 45 years. Three current lines of development in university and industrial research are emphasized. Today, the human problem solving activities are experimentally investigated and analytically described more vigorously than the control activities. Further, improved information presentations and decision support are made possible through new technologies of computer graphics and expert systems. At last, work on a general design methodology for man-machine systems is in progress. The aim is to better support human operators of dynamic technological systems as well as designers of graphics for visual display units and of dialogue styles. Thereby, safety and availability of the complete system can be increased. (orig.) [de

Protein Degradation in Normal and Beige (Chediak-Higashi) Mice

Science.gov (United States)

Lyons, Robert T.; Pitot, Henry C.

1978-01-01

The beige mouse, C57BL/6 (bg/bg), is an animal model for the Chediak-Higashi syndrome in man, a disease characterized morphologically by giant lysosomes in most cell types. Half-lives for the turnover of [14C]bicarbonate-labeled total soluble liver protein were determined in normal and beige mice. No significant differences were observed between the normal and mutant strain for both rapidly and slowly turning-over classes of proteins. Glucagon treatment during the time-course of protein degradation had similar effects on both normal and mutant strains and led to the conclusion that the rate of turnover of endogenous intracellular protein in the beige mouse liver does not differ from normal. The rates of uptake and degradation of an exogenous protein were determined in normal and beige mice by intravenously injecting 125I-bovine serum albumin and following, in peripheral blood, the loss with time of phosphotungstic acid-insoluble bovine serum albumin and the parallel appearance of phosphotungstic acid-soluble (degraded) material. No significant differences were observed between beige and normal mice in the uptake by liver lysosomes of 125I-bovine serum albumin (t½ = 3.9 and 2.8 h, respectively). However, it was found that lysosomes from livers of beige mice released phosphotungstic acid-soluble radioactivity at a rate significantly slower than normal (t½ = 6.8 and 3.1 h, respectively). This defect in beige mice could be corrected by chronic administration of carbamyl choline (t½ = 3.5 h), a cholinergic agonist which raises intracellular cyclic GMP levels. However, no significant differences between normal and beige mice were observed either in the ability of soluble extracts of liver and kidney to bind [3H]cyclic GMP in vitro or in the basal levels of cyclic AMP in both tissues. The relevance of these observations to the presumed biochemical defect underlying the Chediak-Higashi syndrome is discussed. PMID:202611

Propulsive options for a manned Mars transportation system

International Nuclear Information System (INIS)

Braun, R.D.; Blersch, D.J.

1989-01-01

In this investigation, five potential manned Mars transportation systems are compared. These options include: (1) a single vehicle, chemically propelled (CHEM) option, (2) a single vehicle, nuclear thermal propulsion (NTP) option, (3) a single vehicle solar electric propulsion (SEP) option, (4) a single vehicle hybrid nuclear electric propulsion (NEP)/CHEM option, and (5) a dual vehicle option (NEP cargo spacecraft and CHEM manned vehicle). In addition to utilizing the initial vehicle weight in low-earth orbit as a measure of mission feasibility, this study addresses the major technological barriers each propulsive scenario must surpass. It is shown that instead of a single clearly superior propulsion system, each means of propulsion may be favored depending upon the specified program policy and the extent of the desired manned flight time. Furthermore, the effect which aerobraking and multiple transfer cycles have upon mission feasibility is considered. 18 refs

Full Text Available The dissemination and exploitation of cultural heritage milestones by using multimedia and interactive technologies continuously and quickly grows capturing the attention of academia and companies. It is necessary to adopt the state of the art technologies to present and make bi-directional the interaction of users with cultural heritage objects. In this work, we present two different applications of novel technologies applied to the Vitruvian man of Leonardo. The first application is the mirror that exploits a 3D depth sensor to compare the proportions of a user with the perfect ones of the Vitruvian man. The second application is a complex interaction between a complete novel 3D model of the Leonardo’s Vitruvian Man, sounds and image effects inside a 360-degrees hologram. These two systems are the results of interaction between academia and the 3D EVE spin-off company.

Thoughts on the cultural evolution of man. Developmental imprinting and transgenerational effect.

Science.gov (United States)

Csaba, György

2007-01-01

The biological evolution of man stopped since it has been conveyed to the objects, created by man. This paper introduces the concept of "conveyed evolution". Being part of the cultural evolution, the conveyed evolution is a continuation of the biological one. There are several similarities between the laws of biological and conveyed evolution, albeit the differences are important as well. Some laws of the conveyed evolution are described here. The conveyed evolution has man-made repair mechanisms (medicine, protection of environment) which defend man from harm. Man's fragility limits the progress of conveyed evolution. However, artificial compounds or environmental pollutants which are provoked by the conveyed evolution induce chemical (hormonal) imprinting in the developmental critical periods, which is transmitted to the progeny generations (transgenerational effect). This could cause evolutionary alterations without mutation.

Leila Mir Mojarabian

Full Text Available This research is a critical analysis on the place of human and his integration with religious issues, and the subject of disobedience and rebellion. In addition, topics such as reward, punishment, redemption and salvation of mankind in two great works of literature of the world, Masnavi by Mawlana and Paradise Lost by Milton have been comparatively discussed. Rumi's poetry and thought has been accepted by commons and special people in Iran and the world. Rumi is one of the few supreme poets in Persian language and the world. Generally, Milton has Known as the greatest English poet after Shakespeare, and his Paradise Lost as the greatest English fiction poem. This work is a the well-known epics of human-divine composed in live new languages, and comparing these two works even in one field of speech, indeed is the comparison of two thoughts, two nations, and two ancient cultures. The author attempts to examine the similarities and contrasts of the two poems of these two great poets on the subjects of human, God, and Satan and the world, to achieve the analytical and critical comparison of them in this context. In this paper the author tries to base the Paradise Lost of Milton and compare it with the ideas of Mawlana common to imagine man's first story and his disobedience, religious approaches, and finally the end presumed for mankind. In these two poems, contrast between "God" and "man" is derived from the fundamental relationship between "God" and "man". Milton while calls God, our Heavenly Father and refer to his role of creativity, entitles him as the dominant power, All mighty, the victorious winner, Glorious and Holy ruler, powerful king, and in one word, omnipotent. The Creator that all creatures are worshiping him, the omnipotent could be seen his capability remarks in everywhere, the unique structure of the universe beautiful is his own and the glorious ruler, sitting over the skies, sometimes invisible and sometimes visible, even

Effective selection of transgenic papaya plants with the PMI/Man selection system.

Science.gov (United States)

Zhu, Yun J; Agbayani, Ricelle; McCafferty, Heather; Albert, Henrik H; Moore, Paul H

2005-09-01

The selectable marker gene phospho-mannose isomerase (pmi), which encodes the enzyme phospho-mannose isomerase (PMI) to enable selection of transformed cell lines on media containing mannose (Man), was evaluated for genetic transformation of papaya (Carica papaya L.). We found that papaya embryogenic calli have little or no PMI activity and cannot utilize Man as a carbon source; however, when calli were transformed with a pmi gene, the PMI activity was greatly increased and they could utilize Man as efficiently as sucrose. Plants regenerated from selected callus lines also exhibited PMI activity but at a lower specific activity level. Our transformation efficiency with Man selection was higher than that reported using antibiotic selection or with a visual marker. For papaya, the PMI/Man selection system for producing transgenic plants is a highly efficient addition to previously published methods for selection and may facilitate the stacking of multiple transgenes of interest. Additionally, since the PMI/Man selection system does not involve antibiotic or herbicide resistance genes, its use might reduce environmental concerns about the potential flow of those genes into related plant populations.

Agricultural measures to reduce radiation doses to man caused by severe nuclear accidents

International Nuclear Information System (INIS)

Dorp, F. van; Eleveld, R.; Frissel, M.J.

1981-01-01

Agricultural land and products may become contaminated after a severe nuclear accident. If radiation doses to man caused by the ingestion of contaminated agricultural products from such areas will be unacceptably high, measures to reduce this radiation dose will have to be taken. Radiation doses to man can be estimated by using models which describe quantitatively the transfer of radionuclides through the biosphere. The following processes and pathways are described in this study: accidental releases into atmospheric environments and subsequent nearby deposition; contamination of crops by direct deposition and the subsequent short term pathway (e.g. grass-cow-milk-man); contamination of soil and the subsequent long term pathway (e.g. soil-crop-man, soil-grass-cattle-milk/meat-man). Depending on the degree of contamination and on the estimated radiation doses to man, various measures are advised. (Auth.)

Man-machine supervision; Supervision homme-machine

Energy Technology Data Exchange (ETDEWEB)

Montmain, J. [CEA Valrho, Dir. de l' Energie Nucleaire (DEN), 30 - Marcoule (France)

2005-05-01

Today's complexity of systems where man is involved has led to the development of more and more sophisticated information processing systems where decision making has become more and more difficult. The operator task has moved from operation to supervision and the production tool has become indissociable from its numerical instrumentation and control system. The integration of more and more numerous and sophisticated control indicators in the control room does not necessary fulfill the expectations of the operation team. It is preferable to develop cooperative information systems which are real situation understanding aids. The stake is not the automation of operators' cognitive tasks but the supply of a reasoning help. One of the challenges of interactive information systems is the selection, organisation and dynamical display of information. The efficiency of the whole man-machine system depends on the communication interface efficiency. This article presents the principles and specificities of man-machine supervision systems: 1 - principle: operator's role in control room, operator and automation, monitoring and diagnosis, characteristics of useful models for supervision; 2 - qualitative reasoning: origin, trends, evolutions; 3 - causal reasoning: causality, causal graph representation, causal and diagnostic graph; 4 - multi-points of view reasoning: multi flow modeling method, Sagace method; 5 - approximate reasoning: the symbolic numerical interface, the multi-criteria decision; 6 - example of application: supervision in a spent-fuel reprocessing facility.

Risk-based regulation: Challenges and opportunities

International Nuclear Information System (INIS)

Bari, R.A.

1995-01-01

Over the last twenty years, man has witnessed a gradual but steady movement toward increased usage of risk-based methods and results in the regulatory process. The ''risk perspective'' as a supportive view to existing (non-risk-based or deterministic) information used in decision making has a firm foothold now in most countries that regulate nuclear power. Furthermore, in the areas outside the nuclear power field, such as health risk assessment, risk-based information is used increasingly to make decisions on potential impacts of chemical, biological, and radiological exposures. Some of the principal concepts and issues that are pertinent to risk-based regulation are reviewed. There is a growing interest in most countries in the use of risk-based methods and results to facilitate decision-making associated with regulatory processes. A summary is presented of the challenges and opportunities related to expanded use of risk-based regulation

Heidegger: Sense-Nonsense Dualism of Man in Technology Dimensions

Directory of Open Access Journals (Sweden)

Nathalia Andrea Álvarez

2008-12-01

Full Text Available This article tries to analyze the ontological-existential compromise that man acquires when using new technologies, in the light of theHeideggerian’ proposal. This compromise means, on the one hand, theresponsibility of forgetting the self in technology, which immerses man in a non-sense; and on the other, the will to open himself to the recognition of the ways in which his “being-in-the-world” manifests. To this end, the perils of technological “instrumentalization” will be presented, based upon the Heideggerian explanation about the essence of technology. We will present the Heideggerian concepts of anxiety1 and nothingness concepts, with which we will try to conduct the postmodern man towards the encounter with his original sense.

2000-01-01

Objective: To obtain concentrations of elements in Chinese current foods and their dietary intakes by adult man in order to provide a basis on intake parameters of Chinese Reference Man and make related hygienic evaluation. Methods: With mixed food sample method of total diet study, determination of element concentrations in constituent foods of diets for 4 areas with different diet types was carried out by using NAA, ICP-MS, ICP-AES, AAS and necessary QA measures, and estimation of their daily intakes and hygienic evaluation were also made. Results: The concentrations of 42 elements in 12 categories of foods, their intakes and hygienic evaluation for adult man were obtained. Conclusion: The data on element concentrations in Chinese foods and their dietary intakes were updated and widened. These data provided a new basis for developing the parameters of Chinese Reference Man and revealed some current hygienic problems. For example, from viewpoint of nutrition hygiene the Ca, Zn, and Cu intakes for Chinese Reference Man are insufficient, and from consideration of food hygiene the intakes of Pb,Cd and Na are excessive.. Especially, and Cd average daily intakes of Pb, Cd and Hg have been increased during recent years, those of Pb exceed their ADIs, which should be paid attention to

Purpose: Radioactivity deposition in normal tissues limits the dose deliverable by radiopharmaceuticals (RP) in radioimmunotherapy (RIT). This study investigated the absorbed radiation dose in normal tissues for prostate cancer patients in comparison to breast cancer patients for 2 RPs using the monoclonal antibody (MAb) m170. Methods and Materials: 111 In-DOTA-glycylglycylglycyl-L-p-isothiocyanatophenylalanine amide (GGGF)-m170 and 111 In-1,4,7,10-tetraazacyclododecane-N,N',N'',N'''-tetraacetic acid (DOTA) 2-iminothiolane (2IT)-m170, representing the same MAb and chelate with and without a cleavable linkage, were studied in 13 breast cancer and 26 prostate cancer patients. Dosimetry for 9 Y was calculated using 111 In MAb pharmacokinetics from the initial imaging study for each patient, using reference man- and patient-specific masses. Results: The reference man-specific radiation doses (cGy/MBq) were not significantly different for the breast and the prostate cancer patients for both RPs in all but one tissue-RP combination (liver, DOTA-2IT). The patient-specific doses had differences between the groups most of which can be related to weight differences. Conclusions: Similar normal tissue doses were calculated for two groups of patients having different cancers and genders. This similarity combined with continued careful analysis of the imaging data might allow the use of higher starting doses in early phase RIT studies

A manned Mars mission will involve a small crew and many complex tasks. The productivity of the crew and the entire mission will depend significantly on effective automation of these tasks and the ease with which the crew can interface with them. The technology to support a manned Mars mission is available today; however, evolving software and electronic technology are enabling many interesting possibilities for increasing productivity and safety while reducing life cycle cost. Some of these advanced technologies are identified.

Man-Robot Symbiosis: A Framework For Cooperative Intelligence And Control

Science.gov (United States)

Parker, Lynne E.; Pin, Francois G.

1988-10-01

The man-robot symbiosis concept has the fundamental objective of bridging the gap between fully human-controlled and fully autonomous systems to achieve true man-robot cooperative control and intelligence. Such a system would allow improved speed, accuracy, and efficiency of task execution, while retaining the man in the loop for innovative reasoning and decision-making. The symbiont would have capabilities for supervised and unsupervised learning, allowing an increase of expertise in a wide task domain. This paper describes a robotic system architecture facilitating the symbiotic integration of teleoperative and automated modes of task execution. The architecture reflects a unique blend of many disciplines of artificial intelligence into a working system, including job or mission planning, dynamic task allocation, man-robot communication, automated monitoring, and machine learning. These disciplines are embodied in five major components of the symbiotic framework: the Job Planner, the Dynamic Task Allocator, the Presenter/Interpreter, the Automated Monitor, and the Learning System.

Stromal-epithelial interactions mediate both breast development and breast cancer progression. In the present work, we evaluated the effects of conditioned media (CMs) of human adipose tissue explants from normal (hATN) and tumor (hATT) breast on proliferation, adhesion, migration and metalloproteases activity on tumor (MCF-7 and IBH-7) and non-tumor (MCF-10A) human breast epithelial cell lines. Human adipose tissues were obtained from patients and the conditioned medium from hATN and hATT collected after 24 h of incubation. MCF-10A, MCF-7 and IBH-7 cells were grown and incubated with CMs and proliferation and adhesion, as well as migration ability and metalloprotease activity, of epithelial cells after exposing cell cultures to hATN- or hATT-CMs were quantified. The statistical significance between different experimental conditions was evaluated by one-way ANOVA. Tukey's post hoc tests were performed. Tumor and non-tumor breast epithelial cells significantly increased their proliferation activity after 24 h of treatment with hATT-CMs compared to control-CMs. Furthermore, cellular adhesion of these two tumor cell lines was significantly lower with hATT-CMs than with hATN-CMs. Therefore, hATT-CMs seem to induce significantly lower expression or less activity of the components involved in cellular adhesion than hATN-CMs. In addition, hATT-CMs induced pro-MMP-9 and MMP-9 activity and increased the migration of MCF-7 and IBH-7 cells compared to hATN-CMs. We conclude that the microenvironment of the tumor interacts in a dynamic way with the mutated epithelium. This evidence leads to the possibility to modify the tumor behavior/phenotype through the regulation or modification of its microenvironment. We developed a model in which we obtained CMs from adipose tissue explants completely, either from normal or tumor breast. In this way, we studied the contribution of soluble factors independently of the possible effects of direct cell contact.

Estimate of man-rem expenditures for a mature CANDU 600 MW(e) station

International Nuclear Information System (INIS)

Kuperman, I.

1978-08-01

In recent years, man-rem expenditures at operating stations have come under close scrutiny in order to reduce operating personnel dosage. This increased awareness has led to concerted efforts to improve station design and to improve operating procedures to achieve lower man-rem expenditures. This paper is intended to highlight design improvements that have been made in the CANDU 600 MW(e) design and to show how these improvements will reduce man-rem expenditures. Other considerations, such as station decontaminations of the primary heat transport system and the fuelling machines and stricter chemistry control are presently available to help reduce man-rem consumption. Also, station management operating policy should emphasize man-rem awareness. (author)

Engineering the yeast Yarrowia lipolytica for the production of therapeutic proteins homogeneously glycosylated with Man8GlcNAc2 and Man5GlcNAc2

2012-05-01

Full Text Available Abstract Background Protein-based therapeutics represent the fastest growing class of compounds in the pharmaceutical industry. This has created an increasing demand for powerful expression systems. Yeast systems are widely used, convenient and cost-effective. Yarrowia lipolytica is a suitable host that is generally regarded as safe (GRAS. Yeasts, however, modify their glycoproteins with heterogeneous glycans containing mainly mannoses, which complicates downstream processing and often interferes with protein function in man. Our aim was to glyco-engineer Y. lipolytica to abolish the heterogeneous, yeast-specific glycosylation and to obtain homogeneous human high-mannose type glycosylation. Results We engineered Y. lipolytica to produce homogeneous human-type terminal-mannose glycosylated proteins, i.e. glycosylated with Man8GlcNAc2 or Man5GlcNAc2. First, we inactivated the yeast-specific Golgi α-1,6-mannosyltransferases YlOch1p and YlMnn9p; the former inactivation yielded a strain producing homogeneous Man8GlcNAc2 glycoproteins. We tested this strain by expressing glucocerebrosidase and found that the hypermannosylation-related heterogeneity was eliminated. Furthermore, detailed analysis of N-glycans showed that YlOch1p and YlMnn9p, despite some initial uncertainty about their function, are most likely the α-1,6-mannosyltransferases responsible for the addition of the first and second mannose residue, respectively, to the glycan backbone. Second, introduction of an ER-retained α-1,2-mannosidase yielded a strain producing proteins homogeneously glycosylated with Man5GlcNAc2. The use of the endogenous LIP2pre signal sequence and codon optimization greatly improved the efficiency of this enzyme. Conclusions We generated a Y. lipolytica expression platform for the production of heterologous glycoproteins that are homogenously glycosylated with either Man8GlcNAc2 or Man5GlcNAc2 N-glycans. This platform expands the utility of Y. lipolytica as a

Full Text Available Russia has more than 2200 reservoirs and large ponds. As time went by, ponds lost their importance in some aspects of human life, while newly created man-made seas impacted the nature and the people in two ways. The costs involved in designing, constructing, and operating the artificial seas, especially on the plains, have been too high to consider them as an undisputed achievement of the Soviet scientists transforming the nature. This paper discusses the problem of ponds and man-made seas in Russia.

Kant's answer to the question 'what is man?' and its implications for anthropology.

Science.gov (United States)

Cohen, Alix A

2008-12-01

This paper examines Kant's anthropological project and its relationship to his conception of 'man' in order to show that Kant's answer to the question 'what is man?' entails a decisive re-evaluation of traditional conceptions of human nature. I argue that Kant redirects the question 'what is man?' away from defining man in terms of what he is, and towards defining him in terms of what he does, in particular through the distinction between three levels of what I will call 'man's praxis': the levels of technicality, prudence, and morality. As soon as man is understood in terms of what he makes of himself rather than in terms of what he is, two crucial issues arise: what is the purpose of his making? And how can he reach this destination? My claim is that whilst the first question is answered by ethics and a doctrine of prudence, the second question is answered by anthropology. In this sense, anthropology plays the crucial role of identifying the worldly helps and hindrances to the realisation of man's purposes--and this is the reason why it should be understood as a 'pragmatic' discipline.

1988-04-01

This report presents a proposal of referent collective dose (man-rem) values for occupational exposure related to operation of French pressurized water reactors. These values, permitting adequate choice of protection both at design and operation level, are dependent on the level of annual individual doses. The man-rem value, originating from annual individual doses less than 0.5 rem are estimated to 1 kf. The proposed value is 20 kf for annual individual exposures between 0.5 and 3 rem, and 90 kf for annual individual exposures between 3 and 5 rem. (author) [fr

Radiocaesium transfer to man from moose and roe deer in Sweden

Johanson, Karl J.; Bergstroem, R.

1994-01-01

Studies of radiocaesium in the forest ecosystems in Sweden resulted in aggregated transfer factors quantified for the transfer of 137 Cs from soil to moose and roe deer. These aggregated transfer factors were 0.02 m 2 kg -1 for moose and 0.05 m 2 kg -1 for roe deer. There seems to be no decrease in the 137 Cs activity concentrations in moose harvested in our research area and therefore we suggest the use of the physical half-life of 137 Cs (30 years) as the effective ecological half-life. The time-integrated transfer of 137 Cs from the Chernobyl fall-out to man by moose in Sweden was calculated and found to be 115 GBq, corresponding to 1500 man Sv for moose. The time-integrated transfer by roe deer to man was estimated to be between 25-48 GBq, corresponding to 327-620 man Sv for roe deer. The annual transfer of 137 Cs to man by moose has varied between 2.0-2.7 GBq, corresponding to 27-34 man Sv. Depending on the group studied, the mean annual transfer of 137 Cs can be calculated to be from about 250 to 43'000 Bq. For example, the mean annual transfer of 137 Cs by moose to hunters and their families in Gaevle commune, the most affected commune in Sweden, was estimated to be about 26'000 Bq, corresponding to 0.34 mSv

A new tool for man/machine integration

International Nuclear Information System (INIS)

Sommer, W.C.

1981-01-01

A popular term within the nuclear power industry today, as a result of TMI, is man/machine interface. It has been determined that greater acknowledgement of this interface is necessary within the industry to integrate the design and operational aspects of a system. What is required is an operational tool that can be used early in the engineering stages of a project and passed on later in time to those who will be responsible to operate that particular system. This paper discusses one such fundamental operations tool that is applied to a process system, its display devices, and its operator actions in a methodical fashion to integrate the machine for man's understanding and proper use. This new tool, referred to as an Operational Schematic, is shown and described. Briefly, it unites, in one location, the important operational display devices with the system process devices. A man can now see the beginning and end of each information and control loop to better understand its function within the system. A method is presented whereby in designing for operability, the schematic is utilized in three phases. The method results in two basic documents, one describes ''what'' is to be operated and the other ''how'' it is to be operated. This integration concept has now considered the hardware spectrum from sensor-to-display and operated the display (on paper) to confirm its operability. Now that the design aspects are complete, the later-in-time operational aspects need to be addressed for the man using the process system. Training personnel in operating and testing the process system is as important as the original design. To accomplish these activities, documents are prepared to instruct personnel how to operate (and test) the system under a variety of circumstances

The PH-D proposal - A manned mission to PHOBOS and Deimos

Science.gov (United States)

Singer, S. F.

The rationale for a manned mission to the satellites of Mars is discussed. The view has been expressed that NASA must define a major program to follow the Shuttle and to utilize it. However, such a program could not be initiated and proceed without public support, and to obtain this support, public interest would have to be excited. It is shown that, of a number of possible targets for manned exploration in the solar system, Mars appears to be the only possible candidate. Attention is given to a comparison of three Mars missions, a Mars 1984 mission, a manned landing on Mars surface, a manned landing on Phobos and Deimos (Ph-D project), putting men in Mars orbit, the capabilities of the Ph-D mission, a description of the spacecraft, a Ph-D project operations plan, and aspects of timing, technology, and costs.

Marie Curie was awarded the Nobel Prize in chemistry 1911. During the preceding year a rumour had circulated in Stockholm that she had had an affaire with one of her assistants. She received a letter, in which she was told that there had been strong opposition to her election not on scientific but moral grounds, and that she should not go to Stockholm, because nobody could forsee what reactions her appearance at the prize ceremony could evoke. Emil Kleen, a man of violent temper and radical opinions, reacted strongly to these rumours. He wrote a paper, with a violent attack on Gustaf Retzius, previous professor of Histology at Karolinska Institutet. Rightly or wrongly he suspected him to be the author of the infamous letter. Retzius is described as a dilletant in scientific matters, as a "sexual hyena" and a garroulus old man. This portrait of Retzius is of course most unfair, but the portrait of Emil Kleen by the famous swedish artist Bruno Liljefors is a masterpiece and one of the most valuable of the Swedish Medical Association.

Natural and man-made terrestrial electromagnetic noise: an outlook

Directory of Open Access Journals (Sweden)

A. Meloni

2007-06-01

Full Text Available The terrestrial environment is continuously exposed to electromagnetic radiations which set up a «background» electromagnetic noise. Within the Non Ionizing Radiation band (NIR, i.e. for frequencies lower than 300 GHz, this background can have a natural or an artificial origin. Natural origins of electromagnetic radiations are generally atmospheric or cosmic while artificial origins are technological applications, power transmission, communications, etc. This paper briefly describes the natural and man-made electromagnetic noise in the NIR band. Natural noise comes from a large variety of sources involving different physical phenomena and covering a wide range of frequencies and showing various propagation characteristics with an extremely broad range of power levels. Due to technological growth man-made electromagnetic noise is nowadays superimposed on natural noise almost everywhere on Earth. In the last decades man-made noise has increased dramatically over and above the natural noise in residential and business areas. This increase has led some scientists to consider possible negative effects of electromagnetic waves on human life and living systems in general. Accurate measurements of natural and man-made electromagnetic noise are necessary to understand the relative power levels in the different bands and their influence on life.

Full Text Available Warship Man-Machine-Environment System Engineering (MMESE is an integral part of the overall design, and its design principles were proposed according to safety, efficiency, comfort and pleasure. The typical characteristics of MMESE are summarized. The operating environment is extremely terrible on long voyages. High level collaboration is required due to the complex task system and large manpower demand. Owing to the dense computer interface information, the mental cognitive burden on the crew is heavy. The MMESE technology system is divided into four parts:man-machine coordinated, man-environment coordinated, the evaluation of man-machine-environment characteristics and the ergonomic simulation. Based on the MMESE development venation in this paper, the overseas and domestic research statuses are expounded. Interactive optimization can be realized according to the following aspects:researching the basic human characteristics of the crew, applying this to the warship's overall design, and formulating relevant ergonomic standards and norms. Next, Human System Integration (HSI professional engineering was introduced comprehensively into the marines in order to achieve an optimal system. On this basis, we completed the future development trend analysis. All these studies and results have some reference meaning for guiding the integrated optimization of warships as a whole, downsizing the manpower and improving efficiency.

We studied the expression of DMBT1 (deleted in malignant brain tumor 1), a putative tumor suppressor gene, in normal, proliferative, and malignant breast epithelium and its possible relation to cell cycle. Sections from 17 benign lesions and 55 carcinomas were immunostained with anti DMBT1 antibody (DMBTh12) and sections from 36 samples, were double-stained also with anti MCM5, one of the 6 pre-replicative complex proteins with cell proliferation-licensing functions. DMBT1 gene expression at mRNA level was assessed by RT-PCR in frozen tissues samples from 39 patients. Normal glands and hyperplastic epithelium in benign lesions displayed a luminal polarized DMBTh12 immunoreactivity. Normal and hyperplastic epithelium adjacent to carcinomas showed a loss of polarization, with immunostaining present in basal and perinuclear cytoplasmic compartments. DMBT1 protein expression was down-regulated in the cancerous lesions compared to the normal and/or hyperplastic epithelium adjacent to carcinomas (3/55 positive carcinomas versus 33/42 positive normal/hyperplastic epithelia; p = 0.0001). In 72% of cases RT-PCR confirmed immunohistochemical results. Most of normal and hyperplastic mammary cells positive with DMBTh12 were also MCM5-positive. The redistribution and up-regulation of DMBT1 in normal and hyperplastic tissues flanking malignant tumours and its down-regulation in carcinomas suggests a potential role in breast cancer. Moreover, the concomitant expression of DMTB1 and MCM5 suggests its possible association with the cell-cycle regulation

Organotypic culture of normal, dysplastic and squamous cell carcinoma-derived oral cell lines reveals loss of spatial regulation of CD44 and p75 NTR in malignancy.

Dalley, Andrew J; AbdulMajeed, Ahmad A; Upton, Zee; Farah, Camile S

2013-01-01

Oral squamous cell carcinomas (OSCC) often arise from dysplastic lesions. The role of cancer stem cells in tumour initiation is widely accepted, yet the potential existence of pre-cancerous stem cells in dysplastic tissue has received little attention. Cell lines from oral diseases ranging in severity from dysplasia to malignancy provide opportunity to investigate the involvement of stem cells in malignant progression from dysplasia. Stem cells are functionally defined by their ability to generate hierarchical tissue structures in consortium with spatial regulation. Organotypic cultures readily display tissue hierarchy in vitro; hence, in this study, we compared hierarchical expression of stem cell-associated markers in dermis-based organotypic cultures of oral epithelial cells from normal tissue (OKF6-TERT2), mild dysplasia (DOK), severe dysplasia (POE-9n) and OSCC (PE/CA P J15). Expression of CD44, p75(NTR), CD24 and ALDH was studied in monolayers by flow cytometry and in organotypic cultures by immunohistochemistry. Spatial regulation of CD44 and p75(NTR) was evident for organotypic cultures of normal (OKF6-TERT2) and dysplasia (DOK and POE-9n) but was lacking for OSCC (PE/CA PJ15)-derived cells. Spatial regulation of CD24 was not evident. All monolayer cultures exhibited CD44, p75(NTR), CD24 antigens and ALDH activity (ALDEFLUOR(®) assay), with a trend towards loss of population heterogeneity that mirrored disease severity. In monolayer, increased FOXA1 and decreased FOXA2 expression correlated with disease severity, but OCT3/4, Sox2 and NANOG did not. We conclude that dermis-based organotypic cultures give opportunity to investigate the mechanisms that underlie loss of spatial regulation of stem cell markers seen with OSCC-derived cells. © 2012 John Wiley & Sons A/S.

Bioethics against disappearance of a man a prism of general and criminal-law theory

Trajković Marko

Full Text Available Bioethics, as a meeting point, engrossed with its fight against the disappearance of the man, both general and criminal-law theory. Actually, its 'care' for the man is an issue that comes before general and criminal-law theory. While the forms of disappearance of the man are very diverse and very often so refined that they cannon sometimes be recognized, the fight against the disappearance of the man must be open, clear and uncompromising. What is the role of law in this fight? The role imposed itself. Even if the law did not want to take part in the fight, it found itself in the middle of the battlefield because human life is protected from beginning to the end by legal norms that should emerge from the best writings of general and criminal-law theory. However, self-sufficiency of law and mere legal positivism are a true obstacle in this battle. This pressure and the lack of questionings are the first step on the road to disappearance of the man, because a man that asks questions is the man that exists. He and his boldness are a barrier to voluntarism. The lack of boldness of the man opens the gates to his disappearance. This boldness has not been taken away from him in the field of bioethics, which is neither secular nor religious, but rather unique as the man is unique.

We intend to show that it is possible to detect man-in-the-middle attacks on SSL and TLS by detecting timing differences between a standard SSL session and an attack we created.

The institutionalization of Jesus' charismatic authority: "Son of Man" as case study1

Directory of Open Access Journals (Sweden)

Yolanda Dreyer

2000-12-01

Full Text Available This article argues that Jesus used the expression "son of man" not in a titular way, but genetically, meaning "humankind". This use of "son of man" developed into a titular usage in which Jesus is identified with "Son of Man". The study shows that Jesus' use of the expression "son of man" should be understood in the context of the "little tradition" which was reinterpreted in terms of the "great tradition" in a titular way. It is argued that this transition from "litle tradition" to "great tradition"can be seen as "false attribution". After Jesus' death when his followers reorganized themselves into a cultic community, they gave Jesus the position "founder of the cult". They did this by making use of honorary titles. The use of the title "Son of Man" for Jesus is interpreted in terms of the social theory of the institutionalization of charismatic authority. The focus is on the title "Son of Man" as it appears in legal sayings or church rules, wisdom sayings and prophetic and apocalyptic sayings.

Man-Made Object Extraction from Remote Sensing Imagery by Graph-Based Manifold Ranking

The automatic extraction of man-made objects from remote sensing imagery is useful in many applications. This paper proposes an algorithm for extracting man-made objects automatically by integrating a graph model with the manifold ranking algorithm. Initially, we estimate a priori value of the man-made objects with the use of symmetric and contrast features. The graph model is established to represent the spatial relationships among pre-segmented superpixels, which are used as the graph nodes. Multiple characteristics, namely colour, texture and main direction, are used to compute the weights of the adjacent nodes. Manifold ranking effectively explores the relationships among all the nodes in the feature space as well as initial query assignment; thus, it is applied to generate a ranking map, which indicates the scores of the man-made objects. The man-made objects are then segmented on the basis of the ranking map. Two typical segmentation algorithms are compared with the proposed algorithm. Experimental results show that the proposed algorithm can extract man-made objects with high recognition rate and low omission rate.

An evaluation of two-channel ChIP-on-chip and DNA methylation microarray normalization strategies

Science.gov (United States)

2012-01-01

Background The combination of chromatin immunoprecipitation with two-channel microarray technology enables genome-wide mapping of binding sites of DNA-interacting proteins (ChIP-on-chip) or sites with methylated CpG di-nucleotides (DNA methylation microarray). These powerful tools are the gateway to understanding gene transcription regulation. Since the goals of such studies, the sample preparation procedures, the microarray content and study design are all different from transcriptomics microarrays, the data pre-processing strategies traditionally applied to transcriptomics microarrays may not be appropriate. Particularly, the main challenge of the normalization of "regulation microarrays" is (i) to make the data of individual microarrays quantitatively comparable and (ii) to keep the signals of the enriched probes, representing DNA sequences from the precipitate, as distinguishable as possible from the signals of the un-enriched probes, representing DNA sequences largely absent from the precipitate. Results We compare several widely used normalization approaches (VSN, LOWESS, quantile, T-quantile, Tukey's biweight scaling, Peng's method) applied to a selection of regulation microarray datasets, ranging from DNA methylation to transcription factor binding and histone modification studies. Through comparison of the data distributions of control probes and gene promoter probes before and after normalization, and assessment of the power to identify known enriched genomic regions after normalization, we demonstrate that there are clear differences in performance between normalization procedures. Conclusion T-quantile normalization applied separately on the channels and Tukey's biweight scaling outperform other methods in terms of the conservation of enriched and un-enriched signal separation, as well as in identification of genomic regions known to be enriched. T-quantile normalization is preferable as it additionally improves comparability between microarrays. In

In the poem "Always", the author Pablo Neruda employs the first person narration to incisively reveal the paradoxical traits in human nature by exploring man in relation to love. "I" play a role shifting from a calm narrator to a furious one, and the last recovering to a mild one, which offers a multiple visual angle to observe humanity. In sum, by means of continuous changes of my inner feelings in the poem, Pablo Neruda reveals the paradoxical humanity .

Man-caused seismicity of Kuzbass

A natural seismicity of Kuznetsk Basin is confined in the main to mountain frame of Kuznetsk hollow. In this paper materials of experimental work with local station networks within sediment basin are presented. Two types of seismicity display within Kuznetsk hollow have been understood: first, man-caused seismic processes, confined to mine working and concentrated on depths up to one and a half of km; secondly, seismic activations on depths of 2-56 km, not coordinated in plan with coal mines. Every of studied seismic activations consists of large quantity of earthquakes of small powers (Ms=1-3). From one to first tens of earthquakes were recorded in a day. The earthquakes near mine working shift in space along with mine working, and seismic process become stronger at the instant a coal-plough machine is operated, and slacken at the instant the preventive works are executed. The seismic processes near three lavas in Kuznetsk Basin have been studied in detail. Uplift is the most typical focal mechanism. Activated zone near mine working reach in diameter 1-1,5 km. Seismic activations not linked with mine working testify that the subsoil of Kuznetsk hollow remain in stress state in whole. The most probable causes of man-caused action on hollow are processes, coupled with change of physical state of rocks at loss of methane from large volume or change by mine working of rock watering in large volume. In this case condensed rocks, lost gas and water, can press out upwards, realizing the reverse fault mechanism of earthquakes. A combination of stress state of hollow with man-caused action at deep mining may account for incipient activations in Kuznetsk Basin. Today earthquakes happen mainly under mine workings, though damages of workings themselves do not happen, but intensive shaking on surface calls for intent study of so dangerous phenomena. In 2009 replicates of the experiment on research of seismic activations in area of before investigated lavas have been conducted

We have previously shown a differential expression of a family of mitochondrial ncRNAs in normal and cancer cells. Normal proliferating cells and cancer cells express the sense mitochondrial ncRNA (SncmtRNA). In addition, while normal proliferating cells express two antisense mitochondrial ncRNAs (ASncmtRNAs-1 and -2), these transcripts seem to be universally down-regulated in cancer cells. In situ hybridization (ISH) of some normal and cancer tissues reveals nuclear localization of these transcripts suggesting that they are exported from mitochondria. FISH and confocal microscopy, in situ digestion with RNase previous to ISH and electron microscopy ISH was employed to confirm the extra-mitochondrial localization of the SncmtRNA and the ASncmtRNAs in normal proliferating and cancer cells of human and mouse. In normal human kidney and mouse testis the SncmtRNA and the ASncmtRNAs were found outside the organelle and especially localized in the nucleus associated to heterochromatin. In cancer cells, only the SncmtRNA was expressed and was found associated to heterochromatin and nucleoli. The ubiquitous localization of these mitochondrial transcripts in the nucleus suggests that they are new players in the mitochondrial-nuclear communication pathway or retrograde signaling. Down regulation of the ASncmtRNAs seems to be an important step on neoplastic transformation and cancer progression.

The strangest man. The hidden life of Paul Dirac

International Nuclear Information System (INIS)

Farmelo, Graham

2016-01-01

The Strangest Man is the Costa Biography Award-winning account of Paul Dirac, the famous physicist sometimes called the British Einstein. He was one of the leading pioneers of the greatest revolution in twentieth-century science: quantum mechanics. The youngest theoretician ever to win the Nobel Prize for Physics, he was also pathologically reticent, strangely literal-minded and legendarily unable to communicate or empathize. Through his greatest period of productivity, his postcards home contained only remarks about the weather. Based on a previously undiscovered archive of family papers, Graham Farmelo celebrates Dirac's massive scientific achievement while drawing a compassionate portrait of his life and work. Farmelo shows a man who, while hopelessly socially inept, could manage to love and sustain close friendship. The Strangest Man is an extraordinary and moving human story, as well as a study of one of the most exciting times in scientific history.

But observe that this undeniable reality, as analyzed various researchers through what has come to be called Men's studies, has proven to be a fallacy difficult to maintain throughout history and today turns into fallacious and ineffective against changes in our current existing corporate models.

BACKGROUND: The microRNA-200 family participates in the maintenance of an epithelial phenotype and loss of its expression can result in epithelial to mesenchymal transition (EMT). Furthermore, the loss of expression of miR-200 family members is linked to an aggressive cancer phenotype. Regulation of the miR-200 family expression in normal and cancer cells is not fully understood. METHODOLOGY/ PRINCIPAL FINDINGS: Epigenetic mechanisms participate in the control of miR-200c and miR-141 expression in both normal and cancer cells. A CpG island near the predicted mir-200c/mir-141 transcription start site shows a striking correlation between miR-200c and miR-141 expression and DNA methylation in both normal and cancer cells, as determined by MassARRAY technology. The CpG island is unmethylated in human miR-200/miR-141 expressing epithelial cells and in miR-200c/miR-141 positive tumor cells. The CpG island is heavily methylated in human miR-200c/miR-141 negative fibroblasts and miR-200c/miR-141 negative tumor cells. Mouse cells show a similar inverse correlation between DNA methylation and miR-200c expression. Enrichment of permissive histone modifications, H3 acetylation and H3K4 trimethylation, is seen in normal miR-200c/miR-141-positive epithelial cells, as determined by chromatin immunoprecipitation coupled to real-time PCR. In contrast, repressive H3K9 dimethylation marks are present in normal miR-200c/miR-141-negative fibroblasts and miR-200c/miR-141 negative cancer cells and the permissive histone modifications are absent. The epigenetic modifier drug, 5-aza-2'-deoxycytidine, reactivates miR-200c/miR-141 expression showing that epigenetic mechanisms play a functional role in their transcriptional control. CONCLUSIONS/ SIGNIFICANCE: We report that DNA methylation plays a role in the normal cell type-specific expression of miR-200c and miR-141 and this role appears evolutionarily conserved, since similar results were obtained in mouse.

The influence of radiation on fertility in man

International Nuclear Information System (INIS)

Ash, P.

1980-01-01

Increasing numbers of young people are now being cured of certain neoplasms by radiotherapy and chemotherapy. Such people will naturally wish to lead a normal life and possibly to have children. Therefore the question of the effect of radiation and cytotoxic drugs on the reproductive capacity of these patients has become important. The purpose of this report is to review the information available on the effect of radiation on fertility in man. Direct information on radiation effects on human fertility is available from reports on therapeutic exposure and deliberate experimental exposure. Although the total number of cases involved is small, a number of general principles emerge. In males, fractionated irradiation of the testes may be more harmful than acute, at least up to total doses of about 600 cGy(rad). Fractionated doses greater than 35 cGy cause aspermia, the time taken for recovery increasing with dose, and after more than 200 cGy aspermia may be permanent. In females, response varies with age as well as dose. For example, 400 cGy may cause a 30% incidence of sterility in young women, but in women aged above 40 years it results in 100% sterility. However, individuals of either sex show a degree of variation in their response to irradiation. (author)

[Food value of the spiruline algae to man].

Sautier, C; Tremolieres, J

1975-01-01

The acceptability of various culinary products based on the algae spirulina was tested by questionaire: formulas rich in proteins, soups, omelets, desserts. Spirulina are little appreciated in France due to offensive color, smell and taste. Tomato and chocolate are the most acceptable flavors. Lyophilisation is preferable to atomisation, and discoloration using alcohol is preferable to the acetone method. The hydrolysate obtained, having neither the smell nor the taste of algae, is excellent. Nitrogen, sodium and potassium balances were recorded in 5 undernourished subjects fed via a gastric tube. The spirulina provided respectively 15 p. 100 (1 subject), 30 p. 100 (2 subjects), and 50 p. 100 (2 subjects) of the protein ration. There were no intestinal problems. The spirulina did not modify the investigated balances. However, faecal nitrogen increased to 2.08 g (compared to control period values, 1.33 g and 1.51 g). The various coefficients: digestibility, nitrogen retention and protein utilization did not vary. In man as in animals, nitrogen retention is satisfactory, but digestibility is diminished. Uric acid did not vary in the urine, but serum values increased slightly. Ingestion of spirulina in small doses even over a long period should be tolerable in the normal subject.

Ecology and man's environment

Energy Technology Data Exchange (ETDEWEB)

Al-Naqeeb, R

1975-01-01

A new and exciting discipline of human ecology is in the making. It has not, perhaps fortunately, found its bearings yet and remains to date overly dependent upon the limitations of sociology, biology, engineering and the sciences for its general theory, approaches, and philosophy. A new discipline with a world view and focussed on the human being and his habitat will hopefully emerge from a rich dialectic among scientists, humanists and policy makers educated and experienced in a variety of fields and committed to man's welfare. This new discipline and its practitioner must always be open to the revelations their knowledge will bring to man through the environmental processes. The implications of public policy, science and technology of industrial and post-industrial nations are all in need of considered re-examination by us all. Since their early application in these western societies we have witnessed the general downgrading of the world's environment. An ungrading in social priorities for the development of adequate housing, jobs, medical care and education which is almost always lower in rank than they should be is needed. The role of local groups, involving a well-informed and participating citizenship, in this process of changing priorities will always remain of prime importance, but no long-range goal in a rapidly-changing landscape is possible without broad national and local planning which contains ways and means of implementation.

1958 : Manning wants markets

Anon.

2008-01-01

This article described the 2 opposing views in 1958 regarding how the big Montreal refinery market should be served. While the president of Imperial Oil expressed that Montreal refineries should not be forced to use domestic feedstocks, Alberta Premier Ernest Manning urged the Borden Commission to take immediate measures to expand the market for Canadian crude oil into Montreal. Manning argued that the dependence on Venezuelan crude in the Montreal refining market would pose a danger to the stability and development of the oil industry; loss of revenue for municipal, provincial and federal governments; and, an adverse effect on Canada's trade balance with the United States. The Premier suggested that these problems could be avoided by expanding the market for Canadian crude in Ontario and Quebec, in the U.S. Midwest, and in the Pacific Northwest. In 1958, the Canadian oil industry was divided on the Montreal market issue. Other key events in 1958 were listed. Waterton was characterized as Canada's biggest gas field, with reserves of 3 trillion cubic feet. A gas discovery at Berland River was considered the largest single-well exploration find in the world, flowing 27 million cubic feet per day on 1 drillstem. Two new refineries near Vancouver and Toronto were built to raise Canadian refining capacity to 813,000 barrels per day. 1 tab., 1 fig

This paper presents measured results of man-made noise in urban and suburban areas in the 2-GHz band with amplitude probability distribution (APD) in order to evaluate the impact of man-made noise on an experimental cryogenic receiver front-end (CRFE). The CRFE comprises a high-temperature superconducting filter, cryogenically-cooled low-noise amplifier, and highly reliable cryostat that is very compact. The CRFE is anticipated to be an effective way to achieve efficient frequency utilization and to improve the sensitivity of mobile base station receivers. It is important to measure the characteristics of the man-made noise in typical cellular base station antenna environments and confirm their impact on the CRFE reception with APD because if man-made noise has a stronger effect than thermal noise, the CRFE would fail to offer any improvement in sensitivity. The measured results suggest that the contribution of man-made noise in the 2-GHz band can be ignored as far as the wideband code division multiple access (W-CDMA) system is concerned.

Deep-sea disposal: Protecting fish and man

The definition of radioactive waste unsuitable for dumping at sea is based on the protection of man. See IAEA Safety Series No. 78. The development of criteria for assessing the impact on deep sea marine organisms at the population level has been attempted in a report recently published by the IAEA. See IAEA Technical Reports Series, No. 228 (1988). The report indicates that certain radionuclides may give rise to high dose rates to marine organisms if dumping is carried out with the assumptions of instantaneous release at the sea floor and dumping over long periods of time. In the report, a hypothetical dose rate to molluscs from zinc-65, which poses no significant harm to man, has the potential for giving high doses to bottom-dwelling molluscs

Space life science and life support engineering are prominent problems in manned deep space exploration mission. Some typical problems are discussed in this paper, including long-term life support problem, physiological effect and defense of varying extraterrestrial environment. The causes of these problems are developed for these problems. To solve these problems, research on space life science and space medical-engineering should be conducted. In the aspect of space life science, the study of space gravity biology should focus on character of physiological effect in long term zero gravity, co-regulation of physiological systems, impact on stem cells in space, etc. The study of space radiation biology should focus on target effect and non-target effect of radiation, carcinogenicity of radiation, spread of radiation damage in life system, etc. The study of basic biology of space life support system should focus on theoretical basis and simulating mode of constructing the life support system, filtration and combination of species, regulation and optimization method of life support system, etc. In the aspect of space medical-engineering, the study of bio-regenerative life support technology should focus on plants cultivation technology, animal-protein production technology, waste treatment technology, etc. The study of varying gravity defense technology should focus on biological and medical measures to defend varying gravity effect, generation and evaluation of artificial gravity, etc. The study of extraterrestrial environment defense technology should focus on risk evaluation of radiation, monitoring and defending of radiation, compound prevention and removal technology of dust, etc. At last, a case of manned lunar base is analyzed, in which the effective schemes of life support system, defense of varying gravity, defense of extraterrestrial environment are advanced respectively.

As machines have become a more common part of daily life through the passage of time, the idea that the line separating man and machine is slowly fading has become more popular as well. This paper examines three critics of change through their most famous works. One of the most popular views of Mary Shelley's "Frankenstein" is that it is a…

A man in his early 30s with remote history of a febrile rash as a toddler presented to the emergency room following an out-of-hospital cardiac arrest while riding his bicycle. He received bystander cardiopulmonary resuscitation and one shock from an automatic external defibrillator, successfully restoring sinus rhythm. On arrival, he was haemodynamically stable without ECG evidence of ST segment changes to suggest active ischaemia, and an initial troponin I was mildly elevated at 0.10 ng/mL (normal <0.04 ng/mL). A CT angiogram (CTA) was obtained showing a normal-appearing aorta and no abnormal extracardiac findings. Urgent coronary angiography was performed; images are shown in figure 1A-C. Echocardiogram revealed a mildly reduced left ventricular ejection fraction (45%) with a hypokinetic inferior wall.heartjnl;heartjnl-2018-312966v1/F1F1F1Figure 1(A) Right coronary artery angiogram in the left anterior oblique cranial projection.

Heidegger: Sense-Nonsense Dualism of Man in Technology Dimensions

OpenAIRE

Nathalia Andrea Álvarez

2008-01-01

This article tries to analyze the ontological-existential compromise that man acquires when using new technologies, in the light of theHeideggerian’ proposal. This compromise means, on the one hand, theresponsibility of forgetting the self in technology, which immerses man in a non-sense; and on the other, the will to open himself to the recognition of the ways in which his “being-in-the-world” manifests. To this end, the perils of technological “instrumentalization” will be presented, based ...

Absolute quantification of pharmacokinetic distribution of RES colloids in individuals with normal liver function

Herzog, H.; Spohr, G.; Notohamiprodjo, G.; Feinendegen, L.E.

1987-01-01

Estimates of the radiation dose resulting from liver-spleen scintigraphy 99 TCsup(m)-labelled colloids are based on pharmacokinetic data mainly determined in animals. The aim of this study was to check the pharmacokinetic data by direct, absolute in vivo quantification in man. Liver and spleen activities were directly measured using a double-energy window technique. Activities in other organs were quantified by conjugate whole-body scans. All measurement procedures were checked using the whole-body Alderson phantom. Pharmacokinetic data for sulphur colloid, tin colloid, human serum albumin (HSA) millimicrospheres, and phytate were obtained in 13 to 20 normal subjects for each type of colloid. Depending on the colloid type liver uptake was between 54 and 75% of the total administered dose (TAD) and spleen uptake was 3.5 to 21% TAD. Activity measured in blood, urine, lung and thyroid proved to be far from negligible. The results of this work suggest a correction of the animal-based data of colloid distribution and radiation dose on the basis of the direct measurement of absolute uptake in man. (author)

Methods for the determination of the man-Sievert monetary value

International Nuclear Information System (INIS)

Lombard, J.

1986-03-01

To estimate the efficiency of radiological protection systems we have to compare the cost involved in putting each system into operation (cost of protection) to the collective dose that can thus be avoided. This comparison is facilitated if a man-Sievert monetary value is available. The man-Sievert value can be estimated from various detriments than can be attributed to this unitary exposure: whether there are lethal or non-lethal somatic effects, genetic effects and psycho-social effects. ICRP recommends, in its publication 37, to break down the cost of radiological detriment Y into two parts. The first part, Y1=αS, corresponds to the somatic and genetic effects; the second part, Y2=β ΣN j f(Hj), corresponds to the relevant effects of psycho-social considerations. This breakdown leads to the definition of two man-Sievert value components: α, which reflects somatic and genetic detriments; and β, which reflects the psycho-social effects. Several different methods can be used to determine α and β. Here, we will analyse the following: the a priori evaluation based on the Value of Human Life (VHL) or the costs of repair (for non-lethal effects); the a priori evaluation based on the loss of life expectancy; the evaluation based on what an individual would agree to give up to reduce the risk associated to a man Sievert-dose; the evaluation based on the expenses effectively incurred in the past to reduce the risk associated to a man-Sievert dose [fr

Graham Greene and Cuba: Our man in Havana?

Directory of Open Access Journals (Sweden)

Peter Hulme

2008-12-01

Full Text Available [First paragraph] Graham Greene’s novel Our Man in Havana was published on October 6, 1958. Seven days later Greene arrived in Havana with Carol Reed to arrange for the filming of the script of the novel, on which they had both been working. Meanwhile, after his defeat of the summer offensive mounted by the Cuban dictator, Fulgencio Batista, in the mountains of eastern Cuba, just south of Bayamo, Fidel Castro had recently taken the military initiative: the day after Greene and Reed’s arrival on the island, Che Guevara reached Las Villas, moving westwards towards Havana. Six weeks later, on January 1, 1959, after Batista had fled the island, Castro and his Cuban Revolution took power. In April 1959 Greene and Reed were back in Havana with a film crew to film Our Man in Havana. The film was released in January 1960. A note at the beginning of the film says that it is “set before the recent revolution.” In terms of timing, Our Man in Havana could therefore hardly be more closely associated with the triumph of the Cuban Revolution. But is that association merely accidental, or does it involve any deeper implications? On the fiftieth anniversary of novel, film, and Revolution, that seems a question worth investigating, not with a view to turning Our Man in Havana into a serious political novel, but rather to exploring the complexities of the genre of comedy thriller and to bringing back into view some of the local contexts which might be less visible now than they were when the novel was published and the film released.

miR-99 regulates normal and malignant hematopoietic stem cell self-renewal.

The microRNA-99 ( miR-99 ) family comprises a group of broadly conserved microRNAs that are highly expressed in hematopoietic stem cells (HSCs) and acute myeloid leukemia stem cells (LSCs) compared with their differentiated progeny. Herein, we show that miR-99 regulates self-renewal in both HSCs and LSCs. miR-99 maintains HSC long-term reconstitution activity by inhibiting differentiation and cell cycle entry. Moreover, miR-99 inhibition induced LSC differentiation and depletion in an MLL-AF9-driven mouse model of AML, leading to reduction in leukemia-initiating activity and improved survival in secondary transplants. Confirming miR-99 's role in established AML, miR-99 inhibition induced primary AML patient blasts to undergo differentiation. A forward genetic shRNA library screen revealed Hoxa1 as a critical mediator of miR-99 function in HSC maintenance, and this observation was independently confirmed in both HSCs and LSCs. Together, these studies demonstrate the importance of noncoding RNAs in the regulation of HSC and LSC function and identify miR-99 as a critical regulator of stem cell self-renewal. © 2017 Khalaj et al.

Effects of dose, species, and dosing vehicle on the disposition of methacrylonitrile (MAN) in male rats

Sanchez, I.M.; Ghanayem, B.I.

1991-01-01

MAN is structurally similar to known carcinogen acrylontrile (AN), with nitriles having similar industrial uses. Current studies were designed to investigate the biological fate of 2- 14 C-MAN in rats. After gavage administration of 115, 11.5 or 1.15 mg MAN/kg in water, F344 male rats were placed in glass metabolism cages and urine, expired air and feces were collected. Rats were sacrificed at various times and concentration of MAN-derived radioactivity in tissues was determined. MAN was rapidly absorbed from the GI tract and distributed to all major tissues. Sixty-70% of the low and medium doses were exhaled as 14 CO 2 in 72 hr compared to 25% of the highest dose. While 40% of the highest dose was expired as organic volatiles in 72 hr, only 9-12% of the low and accounted for 20-30% of all doses within 72 hr after dosing. Comparison of MAN disposition in Sprague-Dawley (SD) and F344 rats at 115 mg/kg revealed that SD rats excreted a greater % of the dose as 14 CO 2 and in the urine than did F344 rats. Administration of 115 mg MAN/kg to SD male rats in safflower oil resulted in increased elimination of MAN-derived radioactivity as CO 2 , volatiles, and in the urine over that observed when administered in water. These results suggest that: (1) saturation of MAN metabolism occurs at high doses: (2) MAN metabolism and disposition differ with the strain of rats studied; (3) MAN disposition may vary with the dosing vehicle used; and (4) MAN metabolism and disposition is apparently different from that reported on AN

Why Cannot Today’s Medicine Tolerate Man?

Directory of Open Access Journals (Sweden)

Farzad Goli

2017-08-01

Full Text Available Today, anyone who has travelled a little through history or reflected on social systems knows that although social systems are established and designed to satisfy our needs and demands, they have needs of their own which guarantee their life and may precede our needs. Hence, these systems, which were supposed to serve us indisputably like the genie, make us serve them in different ways. Medicine is one of such social systems which were undoubtedly established to satisfy our vital need to care and cure. To exist and develop, medicine needs to know and control personal and social conditions, and to actualize this need, it needs knowledge, money, and, perhaps prior to all of these, it needs to be trusted. To know man, he should be completely uncovered, observable, and dissected into his parts and the relationship between his parts should be explained in simple models. And to direct the condition toward maximum health, men should be converted into statistical entities and their individual differences, conditions, and narratives have to be ignored so that they become predictable and, consequently, controllable creatures. The story of relative, and almost necessary, conflict between man and medicine is as simple as it is explained. Before we go any further into the discussion, we should remember that a real man, with his whole phenomenological world and new-emergent and unique properties of autonomy and consciousness, may suddenly behave like a joker and disturb all the rules of medicine's play. It is natural that such subtleties cannot be tolerated by a materialistic model which is relying on knowledge of mechanistic organization of parts. The aim of this theoretical essay was to increase the readers’ awareness of biomedical model restrictions and organized cruelties it imposes on man in practice and theory. The discussion of alternate models which we are turning to recently has been undertaken in other essays.

New dimensions for man. [human functions in future space missions

Science.gov (United States)

Louviere, A. J.

1978-01-01

The functions of man in space have been in a state of constant change since the first manned orbital flight. Initially, the onboard crewmen performed those tasks essential to piloting and navigating the spacecraft. The time devoted to these tasks has steadily decreased and the crewman's time is being allotted to functions other than orbital operations. The evolving functions include added orbital operational capabilities, experimentation, spacecraft maintenance, and fabrication of useful end items. The new functions will include routine utilization of the crewman to extend mission life, satellite retrieval and servicing, remote manipulator systems operations, and piloting of free-flying teleoperator systems. The most demanding tasks are anticipated to be associated with construction of large space structures. The projected changes will introduce innovative designs and revitalize the concepts for utilizing man in space.

Core temperature rhythms in normal and tumor-bearing mice.

Griffith, D J; Busot, J C; Lee, W E; Djeu, D J

1993-01-01

The core temperature temporal behavior of DBA/2 mice (11 normal and 13 with an ascites tumor) was studied using surgically implanted radio telemetry transmitters. Normal mice continuously displayed a stable 24 hour temperature rhythm. Tumor-bearers displayed a progressive deterioration of the temperature rhythm following inoculation with tumor cells. While such disruptions have been noted by others, details on the dynamics of the changes have been mostly qualitative, often due to time-averaging or steady-state analysis of the data. The present study attempts to quantify the dynamics of the disruption of temperature rhythm (when present) by continuously monitoring temperatures over periods up to a month. Analysis indicated that temperature regulation in tumor-bearers was adversely affected during the active period only. Furthermore, it appears that the malignancy may be influencing temperature regulation via pathways not directly attributable to the energy needs of the growing tumor.

Science-and-Technology-oriented-Society and Man

Science.gov (United States)

Fukui, Ken'ichi

This is a special lecture at the 30th anniversary of JICST. To develop science-and-te chnology-oriented society it is important to evaluate and select infinite information resources on science and technology, and to reorganize and apply them. This also relates to humanity. For the future, we have to establish scientific ethics that can exceed the expedience of science and technology. To be concrete, we have to create new industrial value that recovers and reclaims natural resources which men had wasted so far, and we have to establish a new technology to distribute maldistributed industrial benefits equally. And then, the selfcontrol of the human aiming at the harmony of nature and man will secure human liberty, and it will be done by the good function of man's brain.

To explore the differentially expressed proteins in normal cervix, cervical intraepithelial neoplasia (CIN) and cervical squamous cell carcinoma (CSCC) tissues by differential proteomics technique. Cervical tissues (including normal cervix, CIN and CSCC) were collected in Department of Gynecologic Oncology of Beijing Obstetrics and Gynecology Hospital. Two-dimensional fluorescence difference in gel electrophoresis (2-D DIGE) and DeCyder software were used to detect the differentially expressed proteins. Matrix-assisted laser desorption/ionization-time-of-flight tandem mass spectrometry (MALDI-TOF/TOF MS) was used to identify the differentially expressed proteins. Western blot (WB) and immunohistochemistry (IHC) were performed to validate the expressions of selected proteins among normal cervix, CIN and CSCC. 2-D DIGE images with high resolution and good repeatability were obtained. Forty-six differentially expressed proteins (27 up-regulated and 19 down-regulated) were differentially expressed among the normal cervix, CIN and CSCC. 26 proteins were successfully identified by MALDI-TOF/TOF MS. S100A9 (S100 calcium-binding protein A9) was the most significantly up-regulated protein. Eukaryotic elongation factor 1-alpha-1 (eEF1A1) was the most significantly down-regulated protein. Pyruvate kinase isozymes M2 (PKM2) was both up-regulated and down-regulated. The results of WB showed that with the increase in the severity of cervical lesions, the expression of S100A9 protein was significantly increased among the three groups (P = 0.010). The expression of eEF1A1 was reduced but without significant difference (P = 0.861). The expression of PKM2 was significantly reduced (P = 0.000). IHC showed that protein S100A9 was mainly expressed in the cytoplasm, and its positive expression rate was 20.0 % in normal cervix, 70.0 % in CIN and 100.0 % in CSCC, with a significant difference among them (P = 0.006). eEF1A1 was mainly expressed in the cell plasma, and its

Arabidopsis ACA7, encoding a putative auto-regulated Ca(2+)-ATPase, is required for normal pollen development.

Science.gov (United States)

Lucca, Noel; León, Gabriel

2012-04-01

Microgametogenesis is a complex process that involves numerous well-coordinated cell activities, ending with the production of pollen grains. Pollen development has been studied at the cytological level in Arabidopsis and other plant species, where its temporal time course has been defined. However, the molecular mechanism underlying this process is still unclear, since a relative small number of genes and/or processes have been identified as essential for pollen development. We have designed a methodology to select candidate genes for functional analysis, based on transcriptomic data obtained from different stages of pollen development. From our analyses, we selected At2g22950 as a candidate gene; this gene encodes a protein belonging to the auto-regulated Ca(2+)-ATPase family, ACA7. Microarray data indicate that ACA7 is expressed exclusively in developing pollen grains, with the highest level of mRNA at the time of the second pollen mitosis. Our RT-PCR experiments showed that ACA7 mRNA is detected exclusively in developing flowers. Confocal microscopy experiments showed a plasma membrane localization for the recombinant GFP:ACA7 protein. We identified two different insertional mutant lines, aca7-1 and aca7-2; plants from both mutant lines displayed a normal vegetative development but showed large amounts of dead pollen grains in mature flowers assayed by Alexander's staining. Histological analysis indicated that abnormalities are detected after the first pollen mitosis and we found a strong correlation between ACA7 mRNA accumulation and the severity of the phenotype. Our results indicate that ACA7 is a plasma membrane protein that has an important role during pollen development, possibly through regulation of Ca(2+) homeostasis. © Springer-Verlag 2011

Nogo receptor 1 regulates formation of lasting memories

2009-01-01

Formation of lasting memories is believed to rely on structural alterations at the synaptic level. We had found that increased neuronal activity down-regulates Nogo receptor-1 (NgR1) in brain regions linked to memory formation and storage, and postulated this to be required for formation of lasting memories. We now show that mice with inducible overexpression of NgR1 in forebrain neurons have normal long-term potentiation and normal 24-h memory, but severely impaired month-long memory in both passive avoidance and swim maze tests. Blocking transgene expression normalizes these memory impairments. Nogo, Lingo-1, Troy, endogenous NgR1, and BDNF mRNA expression levels were not altered by transgene expression, suggesting that the impaired ability to form lasting memories is directly coupled to inability to down-regulate NgR1. Regulation of NgR1 may therefore serve as a key regulator of memory consolidation. Understanding the molecular underpinnings of synaptic rearrangements that carry lasting memories may facilitate development of treatments for memory dysfunction. PMID:19915139

Complex chromosomal rearrangements (CCRs) are rare events involving more than two chromosomes and over two breakpoints. They are usually associated with infertility or sub fertility in male carriers. Here we report a novel case of a CCR in a 30-year-old oligoasthenosperm man with a history of varicocelectomy, normal testes size and normal endocrinology profile referred for chromosome analysis to the Genetics unit of Royan Reproductive Biomedicine Research Center. Chromosomal analysis was performed using peripheral blood lymphocyte cultures and analyzed by GTG banding. Additional tests such as C-banding and multicolor fluorescence in situ hybridization (FISH) procedure for each of the involved chromosomes were performed to determine the patterns of the segregations. Y chromosome microdeletions in the azoospermia factor (AZF) region were analyzed with multiplex polymerase chain reaction. To identify the history and origin of this CCR, all the family members were analyzed. No micro deletion in Y chromosome was detected. The same de novo reciprocal exchange was also found in his monozygous twin brother. The other siblings and parents were normal. CCRs are associated with male infertility as a result of spermatogenic disruption due to complex meiotic configurations and the production of chromosomally abnormal sperms. These chromosomal rearrangements might have an influence on decreasing the number of sperms.

Regenerative environmental control and life support system (ECLSS) technologies are found by the present evaluation to have reached a degree of maturity that recommends their application to long duration manned missions. The missions for which regenerative ECLSSs are attractive in virtue of the need to avoid expendables and resupply requirements have been identified as that of the long duration LEO Space Station, long duration stays at GEO, a permanently manned lunar base (or colony), manned platforms located at the earth-moon libration points L4 or L5, a Mars mission, deep space exploration, and asteroid exploration. A comparison is made between nonregenerative and regenerative ECLSSs in the cases of 10 essential functions.

NRC regulations and positions concerning decontamination

International Nuclear Information System (INIS)

McCracken, C.

1982-09-01

The U.S. Nuclear Regulatory Commission encourages the use of decontamination to reduce man-rem exposure. The Commission feels that there are several processes developed to the point where soft decontamination can be applied to an entire plant in the near future. A utility can do a decontamination under its own licence without coming in for regulatory review if the process does not involve a change in technical specifications for the plant or does not involve unreviewed safety questions. Prior verbal notification is required for some steam generator secondary side cleaning or for decontamination of individual components that have not been removed from the reactor using chemicals not normally added to the reactor coolant. Prior written notification is required for steam generator secondary side crevice cleaning or sludge removal at a dented unit, or for chemical decontamination of reactor coolant systems or safety-related systems using chemicals not normally added to the coolant

Full Text Available Asymmetry of parkinsonian symptoms is strong evidence toward the diagnosis of Parkinson's disease (PD. Lower body parkinsonism is characteristic in idiopathic normal pressure hydrocephalus (INPH. We report an unusual INPH patient with marked asymmetric and upper body parkinsonism. An 83-year-old man presented with gait impairment and asymmetric clumsiness of movement. According to the Unified Parkinson's Disease Rating Scale (UPDRS, the motor subscore was 12 in the left limb and 8 in the right. The score was 14 for both the upper and lower body. After the cerebrospinal fluid tap test (CSFTT, he showed marked improvement in the upper body score. A loss of asymmetry of parkinsonian signs, with greater improvement in the left limb, was presented. Fluorinated N-3-fluoropropyl-2β-carbomethoxy-3β-(4-iodophenyl-nortropane (F-18 FP-CIT positron emission tomography (PET imaging was normal. In the differential diagnosis of elderly patients presenting with parkinsonism compatible with PD, we might need to consider a diagnosis of INPH.

As differentiated cells, hepatocytes primarily metabolize glucose for ATP production through oxidative phosphorylation of glycolytic pyruvate, whereas proliferative hepatocellular carcinoma (HCC) cells undergo a metabolic shift to aerobic glycolysis despite oxygen availability. Keratins, the intermediate filament (IF) proteins of epithelial cells, are expressed as pairs in a lineage/differentiation manner. Hepatocyte and HCC (hepatoma) cell IFs are made solely of keratins 8/18 (K8/K18), thus providing models of choice to address K8/K18 IF functions in normal and cancerous epithelial cells. Here, we demonstrate distinctive increases in glucose uptake, glucose-6-phosphate formation, lactate release, and glycogen formation in K8/K18 IF-lacking hepatocytes and/or hepatoma cells versus their respective IF-containing counterparts. We also show that the K8/K18-dependent glucose uptake/G6P formation is linked to alterations in hexokinase I/II/IV content and localization at mitochondria, with little effect on GLUT1 status. In addition, we find that the insulin-stimulated glycogen formation in normal hepatocytes involves the main PI-3 kinase-dependent signaling pathway and that the K8/K18 IF loss makes them more efficient glycogen producers. In comparison, the higher insulin-dependent glycogen formation in K8/K18 IF-lacking hepatoma cells is associated with a signaling occurring through a mTOR-dependent pathway, along with an augmentation in cell proliferative activity. Together, the results uncover a key K8/K18 regulation of glucose metabolism in normal and cancerous hepatic cells through differential modulations of mitochondrial HK status and insulin-mediated signaling.

Full Text Available I Norge er ikke surrogati tillatt, og myndighetene fraråder norske statsborgere å benytte seg av surrogati i utlandet. I denne artikkelen fokuserer vi på kommersiell gestational surrogati og stiller spørsmålet: Bør man tillate at norske statsborgere benytter seg av surrogati i India? De etiske problemstillingene rundt surrogati er mange og sammensatte og blir spesielt utfordrende når tjenesten tilbys i et land med store kulturelle og økonomiske forskjeller både internt og i forhold til Norge. Vi baserer analysen og drøftingen av dette etisk utfordrende spørsmålet på Beauchamps og Childress sin veletablerte metodiske tilnærming innen biomedisinsk etikk. Vi anvender de fire allmennmoralske prinsipper: respekt for autonomi, velgjørenhet, ikke-skade og rettferdighet på sakskomplekset for å synliggjøre spenningene involvert i dette etiske dilemmaet. Med full bevissthet om at det ikke finnes noen lettvinte og omkostningsfrie løsninger på dilemmaer generelt og dette spesielt, konkluderer vi med at interessene til de berørte parter, og spesielt surrogatmødrenes, kan bli bedre ivaretatt om surrogati tillates under omfattende reguleringer.

Man-machine interaction in Canadian nuclear power plants

International Nuclear Information System (INIS)

Olmstead, R.A.

1994-01-01

The design of man-machine interaction in the CANDU plants has evolved considerably over several generations of plants, from the first Douglas Point plant through to the next generation of plants represented by new designs like CANDU 3. In the early plants, the control room configuration was based on designers' projections of control interface requirements. With succeeding generations of designs, there has been an evolution towards a more systematic consideration of human strengths and weaknesses, increasing attention to formal requirements definition, and incorporation of a larger base of operational experience. This paper describes the design of the man-machine interaction for third generation CANDU-3 control rooms for improved operator reliability and reduced costs. (author). 13 refs., 3 figs

Differential Gene Expression of Fibroblasts: Keloid versus Normal

Michael F. Angel

2002-11-01

Full Text Available Abstract: This study investigated gene regulation and unique gene products in both keloid (KDF and normal (NDF dermal fibroblasts in established cell lines. For gene regulation, NDF versus KDF were compared using Clontech's Atlas™ Human cDNA Expression Array while unique gene products were studied using RNA Fingerprinting Kit. RNA from each sample was converted to cDNA using oligo-dT primers. Down-regulated genes using Atlas Array in KDF were 1 60 S ribosomal protein, 2 Thioredoxin dependent peroxidase, 3 Nuclease sensitive element DNA binding protein, 4 c-myc purine-binding transcription factor, 5 c-AMP dependent protein kinase, and, 6 Heat Shock Protein 90 kDa. Genes that are up regulated in KDF were 1 Tubulin and 2 Heat Shock Protein 27 kDa. With the differential display, we found 17 bands unique to both KDF and NDF. The specific gene and the manner in which they were differentially regulated have direct implications to understanding keloid fibroblast proliferation.

Full Text Available The aim of this study was to evaluate feed intake, digestibility, nitrogen balance, water balance, and performance of lambs fed diets containing old man saltbush hay associated with a concentrate. Thirty-two castrated feedlot Santa Inês lambs at approximately eight months of age, with 22 ± 1.97 kg body weight, were distributed into a completely randomized experimental design. Acid detergent fiber intake increased (P < 0.05, whereas non-fibrous carbohydrates intake decreased (P < 0.01. Inclusion of old man saltbush in the diet reduced (P < 0.01 the digestibility of dry and organic matter, neutral and acid detergent fiber, and non-fibrous carbohydrates. The intakes of digestible dry and organic matter, ether extract, total carbohydrates, and digestible non-fibrous carbohydrates also decreased (P < 0.01. Inclusion of old man saltbush did not influence water consumption from the trough by the sheep, averaging 4,327.20 mL/day?1. Body weight at slaughter and daily weight gain decreased linearly (P < 0.05 and feed conversion worsened as old man saltbush hay was added to the diet. Inclusion of old man saltbush at up to 40% replacing the concentrate in feedlot lamb diets does not compromise the performance of these animals.

Radiation shield analysis for a manned Mars rover

Radiation shielding for unmanned space missions has been extensively studied; however, designs of man-rated shields are minimal. Engle et al.'s analysis of a man-rated, multilayered shield composed of two and three cycles (a cycle consists of a tungsten and a lithium hydride layer) is the basis for the work reported in this paper. The authors present the results of a recent study of shield designs for a manned Mars rover powered by a 500-kW(thermal) nuclear reactor. A train-type rover vehicle was developed, which consists of four cars and is powered by an SP-100-type nuclear reactor heat source. The maximum permissible dose rate (MPD) from all sources is given by the National Council on Radiation Protection and Measurements as 500 mSv/yr (50 rem/yr) A 3-yr Mars mission (2-yr round trip and 1-yr stay) will deliver a 1-Sv natural radiation dose without a solar particle event, 450 mSv/yr in flight, and an additional 100 mSv on the planet surface. An anomalously large solar particle event could increase the natural radiation dose for unshielded astronauts on the Martian surface to 200 mSv. This limits the MPD to crew members from the nuclear reactor to 300 mSv

Man as a safety problem in technical systems

Compes, P.C.; Wolff, H.A.

Safety engineering derives its justification from the success achieved in maintaining and enlarging safety, more precisely, from activities aimed at avoiding or preventing damage caused by accidents. Man is not only affected by accidents but is also the cause of accidents, either directly or indirectly, and thus is to be regarded as the actual cause or preventer of accidents. The Second International Summer Symposium of the Society for Safety Engineering (GfS) which was held at Duesseldorf in 1980 brought into focus this aspect and the importance to be attached to the individual man and the whole mankind in the field of accident prevention. 'Man as a safety problem in technical systems' - a great and weighty field of problems, the large extent of which and the complex content of which was to be discussed by the programme with its many different contributions, on the one hand by presenting an outline as completely as possible, and on the other hand by finding further-reaching solutions for at least some problems. This was the purpose of the dialogues held between theory and practice on the one hand, and between safety engineering and, in this case, the human sciences on the other hand. (orig./RW) [de

Rhabdomyolysis-Associated Acute Kidney Injury With Normal Creatine Phosphokinase.

Science.gov (United States)

Kamal, Faisal; Snook, Lindsay; Saikumar, Jagannath H

2018-01-01

Rhabdomyolysis is a syndrome characterized by the breakdown of skeletal muscle and leakage of intracellular myocyte contents, such as creatine phosphokinase (CPK) and myoglobin, into the interstitial space and plasma resulting in acute kidney injury (AKI). Elevated CPK of at least 5 times the upper limit of normal is an important diagnostic marker of Rhabdomyolysis. We present a case of rhabdomyolysis with severe AKI with a normal CPK at presentation. A 32-year-old man presented with acute respiratory failure and AKI after an overdose of recreational drugs. Urinalysis at presentation showed trace amounts of blood, identified as rare red blood cells under microscopy. CPK was 156 U/L at presentation. Workup for glomerulonephritis and vasculitis was negative. He was initiated on renal replacement therapy, and a kidney biopsy showed severe acute tubular injury with positive myoglobin casts. Supportive management and renal replacement therapy was provided, and renal function spontaneously improved after a few weeks. This is an uncommon clinical presentation of severe rhabdomyolysis complicated by AKI. This suggests that CPK alone may not be a sensitive marker for rhabdomyolysis-induced AKI in some cases.

Data assimilation within the Advanced Circulation (ADCIRC) modeling framework for the estimation of Manning's friction coefficient

KAUST Repository

Mayo, Talea

2014-04-01

Coastal ocean models play a major role in forecasting coastal inundation due to extreme events such as hurricanes and tsunamis. Additionally, they are used to model tides and currents under more moderate conditions. The models numerically solve the shallow water equations, which describe conservation of mass and momentum for processes with large horizontal length scales relative to the vertical length scales. The bottom stress terms that arise in the momentum equations can be defined through the Manning\\'s n formulation, utilizing the Manning\\'s n coefficient. The Manning\\'s n coefficient is an empirically derived, spatially varying parameter, and depends on many factors such as the bottom surface roughness. It is critical to the accuracy of coastal ocean models, however, the coefficient is often unknown or highly uncertain. In this work we reformulate a statistical data assimilation method generally used in the estimation of model state variables to estimate this model parameter. We show that low-dimensional representations of Manning\\'s n coefficients can be recovered by assimilating water elevation data. This is a promising approach to parameter estimation in coastal ocean modeling. © 2014 Elsevier Ltd.

Conformation of glycomimetics in the free and protein-bound state: structural and binding features of the C-glycosyl analogue of the core trisaccharide alpha-D-Man-(1 --> 3)-[alpha-D-Man-(1 --> 6)]-D-Man.

The conformational properties of the C-glycosyl analogue of the core trisaccharide alpha-D-Man-(1 --> 3)-[alpha-D-Man-(1 --> 6)]-D-Man in solution have been carefully analyzed by a combination of NMR spectroscopy and time-averaged restrained molecular dynamics. It has been found that both the alpha-1,3- and the alpha-1,6-glycosidic linkages show a major conformational averaging. Unusual Phi ca. 60 degrees orientations for both Phi torsion angles are found. Moreover, a major conformational distinction between the natural compound and the glycomimetic affects to the behavior of the omega(16) torsion angle around the alpha-1 --> 6-linkage. Despite this increased flexibility, the C-glycosyl analogue is recognized by three mannose binding lectins, as shown by NMR (line broadening, TR-NOE, and STD) and surface plasmon resonance (SPR) methods. Moreover, a process of conformational selection takes place, so that these lectins probably bind the glycomimetic similarly to the way they recognize the natural analogue. Depending upon the architecture and extension of the binding site of the lectin, loss or gain of binding affinity with respect to the natural analogue is found.

2013-12-01

At 2011 we have described the imbalance of water in Nature as the system [1]. At 2012 we have described water and carbon and the glaciers [2], [3] as creators of the imbalance of Nature. Now we are describing some man-made creators of the imbalance of Nature. The photosynthesis is a powerful creator of the imbalance of Nature. The photosynthesis significantly increases the complexity of the structures and reduces the entropy. Earth's hydrosphere contains water less than it was flowed via photosynthesis. This is an example of the imbalance of involving when the return of water has delayed because water is involved into the processes of life and other processes. People widely use photosynthesis and create not only an additional man-made imbalance of water in Nature, but also the man-made changing the albedo, and a lot of other important parameters of the planet of Earth. All of these processes are significantly imbalanced. The fossil hydrocarbons have accumulated during millions of years, but now are burned. This is an example of the imbalance delay by time. The man-made burning of the hydrocarbons is creating the imbalances of impact or explosive type, because of the burning processes is in millions of times faster than the accumulation processes. Please pay attention to the imbalance of redeployment by places. For example, oil and gas are extracted in one places, and burned in others. During combustion is standing out not only water, but energy, and other components. The temperature in the centers of big cities is always higher and there is dominating the rising air. It pollutes the environment, changes circulations, create greenhouse effect, etc. Other examples of the imbalance of relocation are shown in the production and consumption of food. The irrigation systems transfer water from one place to another. This transfer of water creates a lot of imbalances in change climate, ecosystems, etc in places where water was took and where the water was brought. Usually

Climate and man in the Arctic

International Nuclear Information System (INIS)

1997-01-01

The ever-changing climate shapes the Arctic landscape, influences life conditions for plants and animals and alters the availability of the living resources that play such and important part in the economy of Arctic peoples. It is essential that we try to understand the nature of climatic change and its effects on man and his environment. Only this way can we hope to be able to predict future changes that may have great consequences for the well-being of northern residents. In recent years many research projects have been addressing the subject and important advances have been made. At the same time it has become increasingly evident that the complexity of the whole issue calls for an integration of scientific approaches and for interdisciplinary collaboration. The seminar 'Climate and Man in the Arctic' provided an opportunity both to highlight important areas of climate related research and to discuss more general aspects of arctic research. Eight papers presented at the seminar are published in this volume. (au) 22 refs

Man-machine communication in reactor control using AI methods

Klebau, J.; Lindner, A.; Fiedler, U.

1987-01-01

In the last years the interest in process control has expecially focused on problems of man-machine communication. It depends on its great importance to process performance and user acceptance. Advanced computerized operator aids, e.g. in nuclear power plants, are as well as their man-machine interface. In the Central Institute for Nuclear Research in Rossendorf a computerized operator support system for nuclear power plants is designed, which is involved in a decentralized process automation system. A similar but simpler system, the Hierarchical Informational System (HIS) at the Rossendorf Research Reactor, works with a computer controlled man-machine interface, based on menu. In the special case of the disturbance analysis program SAAP-2, which is included in the HIS, the limits of menu techniques are obviously. Therefore it seems to be necessary and with extended hard- and software possible to realize an user controlled natural language interface using Artificial Intelligence (AI) methods. The draft of such a system is described. It should be able to learn during a teaching phase all phrases and their meanings. The system will work on the basis of a self-organizing, associative data structure. It is used to recognize a great amount of words which are used in language analysis. Error recognition and, if possible, correction is done by means of a distance function in the word set. Language analysis should be carried out with a simplified word class controlled functional analysis. With this interface it is supposed to get experience in intelligent man-machine communication to enhance operational safety in future. (author)

Rare case of primary spinal ependymomatosis occurring in a 26-year-old man: a case report

Directory of Open Access Journals (Sweden)

Kaliaperumal Chandrasekaran

2009-10-01

Full Text Available Abstract Introduction The authors report a rare case of primary spinal ependymomatosis in a young adult man. Multiple primary ependymomatous lesions were seen on magnetic resonance imaging and no anaplasia was identified on the surgical-pathological analysis. The aetio-pathological mechanism and surgical significance of this rare occurrence is discussed. Case presentation A 26-year-old man of Polish origin presented with a ten-day history of pain in the left leg and lower back. This was followed by difficulty in urinating and a decrease in sensation in both legs. Examination revealed pyramidal signs and mild weakness in both lower limbs. He had early sphincter involvement requiring catheterization. Magnetic resonance imaging of the brain was normal. However, that of the spinal cord revealed multiple intradural spinal lesions, both intra- and extramedullary, extending from the cervical cord down to the cauda equina roots. T12-L1 laminectomy was performed. Multiple intradural, extra- and intra-medullary tumors were seen. After the operation, the patient deteriorated with a sensory level at T4. Post-operative cranio-spinal radiotherapy was administered but there was no clinical improvement in the lower limbs. Conclusion Primary spinal ependymomatosis is a rare phenomenon involving multiple spinal segments in the absence of a primary intracranial tumor. Radical excision is unrealistic in this condition. Biopsy followed by radiotherapy is the preferred method of treatment.

[Iron Man: Between Confusion of Identity and Addiction to Technology].

Science.gov (United States)

Chapellon, Sébastien; Houssier, Florian

The fascination surrounding a successful artwork is linked to the fact it faces the viewer to unknown aspects of his/her own psychic life. The same applies to the comics Iron Man. Behind the armour is hiding a man caught up in the traumatic incidences of life. The hero demonstrates a psychic weakness which, despite being deep, is, however, showing universal aspects.The analysis of his misfortunes reveals a narcissistic disorder. The article intends to set out the identity confusion the Marvel's protagonist is trapped in while highlighting the addictive troublesome linking him to his high-tech armour. This article also seeks to attest the fact the symbiosis between Tony Stark and Iron Man is anticipating the evolution of our behaviour with regard to new technologies.To this end, the authors are recalling the episodes of the series. Through the analysis of the confrontational dialogue the hero is maintaining with his iron armour, they explore how the internal experiment related to the sense of identity disorder is figured out. Thus, going through the key moments of the saga, the authors raise the ambiguity of his hero. The metapsychological analysis of the actions undertaken by Iron Man reflects a little-known facet of his personality, revealing a character more tormented than he really looks. However, the point is not to "treat" a fictional man, but to observe how he can help us to understand the internal behaviour of our patients, and also our own.The Faustian drama this comic leads to is hence understood as a living testimony of our own psychic conflicts. Furthermore, the analysis gives rise to a questioning as to the risk of identity confusion the technological progress can create at a time when the Human is more and more depending on the machines he creates himself.

Following infusion of 51Cr-labeled autologous platelets into normal subjects, high-density (HD) and low-density (LD) platelet cohorts were isolated by prolonged centrifugation in isosmotic arabino-galactan (Stractan). Specific radio-activity of LD platelets declined rapidly post-infusion (T1/2 . 1.5 days), but specific radioactivity of HD platelets remained constant or increased over a 3--4-day period and gradually declined for 6--7 days thereafter. These differences were exaggerated when platelet cohorts enriched in LD or HD cells by slow centrifugation in high-density albumin were labeled and transfused. Mean survival of a platelet cohort enriched with HD cells was significantly (P less than 0.02) shorter (7.73 days) than that of a cohort enriched with LD cells (9.33) days). In normal subjects treated with aspirin, capacity for thromboxane synthesis was regained more rapidly (P less than 0.05) in LD than in HD platelets. HD and LD platelets differed only slightly in mean volume (HD platelets . 7.57 mu3, LD platelets . 6.87 mu3, 0.05 less than P less than 0.01). We believe the most logical interpretation of these findings is that under normal conditions in man, newly formed platelets are less dense on the average than total platelets and become more dense as they age in the circulation. Thus, specific radioactivity of LD platelets declines rapidly as these platelets move into a more dense compartment and are replaced by newly formed, unlabelled cells; specific radioactivity of HD platelets remains constant or increases as labelled platelets enter this compartment in numbers equal to or greater than the number leaving it at the end of their life span. The similarity in mean volumes of LD and HD platelets suggests that platelet size is unrelated to platelet age under normal conditions

A model for hematopoietic death in man from irradiation of bone marrow during radioimmunotherapy.

There are numerous institutions worldwide performing clinical trials of radioimmunotherapy (RIT) for cancer. For RIT, an exponentially decaying radionuclide is attached by using a chelating agent to a specific monoclonal or polyclonal tumour antibody (e.g. antiferritin IgG). The major limitation to RIT is toxicity to normal tissue in organs other than the one containing the tumour (e.g. bone marrow). The focus of this manuscript is on modelling the risk (or probability) of hematopoietic death in man for exponentially decaying patterns of high-energy beta irradiation (e.g. 90Y) of bone marrow by radioimmunoglobulin injected into the blood. The analytical solutions presented are only applicable to protocols for which significant uptake of radioactivity by the bone marrow does not occur, and only for high energy beta emitters. However, the generic equation used to obtain the analytical solutions is applicable to any continuous pattern of high energy beta irradiation. A model called the "normalized dose model" was used to generate calculated values for the LD50 as a function of the effective half-time for the radioimmunoglobulin in the blood. A less complicated empirical model was used to describe the calculated values. This model is presumed to be valid for effective half-times in blood of up to about 20 days. For longer effective half-times, the LD50 can be estimated using the normalized-dose model presented. In this manuscript, we also provide a modified Weibull model that allows estimation of the risk of hematopoietic death for single or multiple injections (in one cycle) of radioimmunoglobulin, for patients with normal susceptibility to irradiation and for patients with heightened susceptibility. With the modified Weibull model, the risk of hematopoietic death depends on the level of medical treatment provided to mitigate radiation injuries.

Being together – Exploring the modulation of affect in improvisational music therapy with a man in a persistent vegetative state – a qualitative single case study

Directory of Open Access Journals (Sweden)

Wolfgang Schmid

2016-12-01

Full Text Available This article explores the role of affective expression and modulation as a means of communication in improvisational music therapy with a 44-year-old man living in a persistent vegetative state. Within a practice-based approach two vignettes from music therapy illustrate the regulation of the intensity of affect in an interpersonal relationship. Perspectives from modern attachment theory, developmental psychology, and embodiment research will be introduced and discussed, to theoretically frame and embed the practical work. It is suggested that the bodily-emotional situatedness of the man and the music therapist form the area of exchange for a non-verbal, affect-driven communication. In this way, playing with the affect is the main topic for the encounter, promoting self-organizational processes in both individuals involved.

The institutionalization of Jesus' charismatic authority: "Son of Man" as case study¹

OpenAIRE

Yolanda Dreyer

2000-01-01

This article argues that Jesus used the expression "son of man" not in a titular way, but genetically, meaning "humankind". This use of "son of man" developed into a titular usage in which Jesus is identified with "Son of Man". The study shows that Jesus' use of the expression "son of man" should be understood in the context of the "little tradition" which was reinterpreted in terms of the "great tradition" in a titular way. It is argued that this transition from "litle tradition" to "great t...

The fraction of serotonin extracted on a single passage through the lungs is being used as an early indicator of lung endothelial damage but the existing techniques require multiple arterial blood samples. We have developed a noninvasive technique to measure lung serotonin uptake in man. We utilized the double indicator diffusion principle, a positron camera, 11 C-serotonin as the substrate, and 11 CO-erythrocytes as the vascular marker. From regions of interest around each lung, we recorded time-activity curves in 0.5-sec frames for 30 sec after a bolus injection of first the vascular marker 11 CO-erythrocytes and 10 min later 11 C-serotonin. A second uptake measurement was made after imipramine 25-35 mg was infused intravenously. In three normal volunteers, the single-pass uptake of 11 C-serotonin was 63.9% +/- 3.6%. This decreased in all subjects to a mean of 53.6% +/- 1.4% after imipramine. The rate of lung washout of 11 C was also significantly prolonged after imipramine. This noninvasive technique can be used to measure lung serotonin uptake to detect early changes in a variety of conditions that alter the integrity of the pulmonary endothelium

Dysregulation of the hypothalamic-pituitary-adrenal (HPA) axis has been implicated in the pathophysiology of depression and stress disorders. Glucocorticoids, key regulators of the stress response, exert diverse effects on cellular processes in the hippocampus. Beside non-genomic pathways, glucocorticoid effects are mediated through activation of the glucocorticoid receptor (GR), a ligand activated transcriptional factor that belongs to the nuclear hormone receptor superfamily. We analysed the GR protein levels both in the cytoplasmic and nuclear compartments of the hippocampus of Wistar rats exposed to chronic psychosocial isolation stress upon chronic fluoxetine (FLU) treatment. Under chronic stress, corticosterone levels (CORT) were decreased compared to the control, and treatment with FLU did not change its level in the stressed rats. At the molecular level, FLU normalized the level of nuclear GR protein in the hippocampus of the stressed rats. Discrepancy between normalization of nuclear GR in the hippocampus and lack of normalization of HPA axis activity judged by CORT, suggests that other brain structures such as the amygdale and prefrontal cortex that also regulate HPA axis activity, seem not to be normalized by the FLU treatment used in our study.

Abort trajectory is a passage that ensures the astronauts to return safely to the earth when an emergency occurs. Firstly,the essential elements of mission abort are analyzed entirely based on summarizing the existing studies. Then,abort trajectory requirement and rational selection for different flight phases of typical manned lunar mission are discussed specifically. Considering a trade-off between the two primary constrains of an abort,the return time of flight and energy requirement,a general optimizing method for mission abort is proposed. Finally,some suggestions are given for China’s future manned lunar landing mission.

Research review. Interactions between environmental chemicals and drug biotransformation in man.

Science.gov (United States)

Alvares, A P

1978-01-01

Many factors influence the metabolism of drugs in man. Besides genetic factors, environmental factors may play a significant role in explaining the variation observed in the rates of drug metabolism between different individuals. Intentional or unintentional exposure to environmental chemicals could enhance or inhibit the activity of hepatic mixed function oxidases that metabolise drugs and other foreign chemicals, as well as endogenous substrates such as steroid hormones. A major source of such exposure may be occupational. Exposure to the heavy metal, lead, has been shown to inhibit drug metabolism; whereas intensive exposure to chlorinated insecticides, and other halogenated hydrocarbons such as polychlorinated biphenyls, has been shown to enhance the metabolism of test drugs such as antipyrine and phenylbutazone. An intentional source of exposure to foreign chemicals is cigarette smoke. Cigarette smoke contains polycyclic hydrocarbons, which are known inducers of hepatic mixed function oxidases. A number of studies have shown that cigarette smoking can alter the pharmacological action and/or the metabolism of some drugs. Pharmacokinetic studies have shown that cigarette smoking decreases the bioavailability of phenacetin and increases dosage requirements of theophylline by enhancing their rate of metabolism. Data, which are not very conclusive, indicate that heavy marijuana use may have an inhibitory effect on metabolism of some drugs and an inducing effect on others such as theophylline. Dietary factors may also play a significant role in the regulation of drug metabolism. Charcoal broiling which introduces polycyclic hydrocarbons into foods has been shown to enhance the metabolism of the test drug, antipyrine, and of such commonly used drugs as phenacetin and theophylline. Such intentional or unintentional exposure to environmental chemicals which may alter the rates of drug metabolism in man indicates the importance of individualisation of drug therapy.

The development of a completely new series of gas turbines requires significant capital, resources and know-how. MAN Diesel and Turbo strategically decided to create a small gas turbine in the 6 MW-class. The construction of the Gas Turbine has been on the basis of opportunities in current and future markets and the positioning of the competition, this has determined the characteristics and technical parameters which have been optimised in the 6 MW design. The construction uses extremely high precision engineering so that the assembly of sub-components to modules is a smooth flowing process and can guarantee the high standards both quality and performance which MAN Diesel and Turbo are operating to. The individual components must be tested and thoroughly validated many months before actual assembly of the first machine. These include in particular the compressor of the gas turbine and the combustion chamber. The combustion system required special attention, since the emissions are strongly focused to satisfy stringent environmental requirements. The planned tests are a prerequisite for the construction of such a prototype and must be successfully completed before the Gas Turbine will be accepted into service. (orig.)

The survival rate of septic patients mainly depends on a rapid and reliable diagnosis. A rapid, broad range, specific and sensitive quantitative diagnostic test is the urgent need. Thus, we developed a TaqMan-Based Multiplex real-time PCR assays to identify bloodstream pathogens within a few hours. Primers and TaqMan probes were designed to be complementary to conserved regions in the 16S rDNA gene of different kinds of bacteria. To evaluate accurately, sensitively, and specifically, the known bacteria samples (Standard strains, whole blood samples) are determined by TaqMan-Based Multiplex real-time PCR. In addition, 30 blood samples taken from patients with clinical symptoms of sepsis were tested by TaqMan-Based Multiplex real-time PCR and blood culture. The mean frequency of positive for Multiplex real-time PCR was 96% at a concentration of 100 CFU/mL, and it was 100% at a concentration greater than 1000 CFU/mL. All the known blood samples and Standard strains were detected positively by TaqMan-Based Multiplex PCR, no PCR products were detected when DNAs from other bacterium were used in the multiplex assay. Among the 30 patients with clinical symptoms of sepsis, 18 patients were confirmed positive by Multiplex real-time PCR and seven patients were confirmed positive by blood culture. TaqMan-Based Multiplex real-time PCR assay with highly sensitivity, specificity and broad detection range, is a rapid and accurate method in the detection of bacterial pathogens of sepsis and should have a promising usage in the diagnosis of sepsis. © 2017 Wiley Periodicals, Inc.

To investigate the regulation of MMP-9, TIMP-1, and progesterone via three signal transduction pathways in luteinized granulosa cells from normal ovulatory and PCOD women. In vitro study. Laboratory for Research in Reproductive Sciences, Department of Obstetrics and Gynecology, Ha'Emek Hospital, Afula, Israel. Ten normal ovulatory and 10 women with polycystic ovary disease (PCOD) treated in an assisted reproduction program. Cultured cells were exposed to phorbol 12-myristate 13-acetate (TPA), acting via protein kinase C (PKC), to epidermal growth factor (EGF), acting via protein tyrosine kinase (PTK), and to forskolin, acting via protein kinase A (PKA). Secretion of MMP-9, TIMP-1, and progesterone. Phorbol 12-myristate 13-acetate elicited an increase in MMP-9 and TIMP-1 secretion in both groups and apparently did not affect progesterone secretion. Epidermal growth factor did not change significantly neither MMP-9 nor TIMP-1 secretion but dose dependently decreased MMP-9-TIMP-1 ratio and increased progesterone secretion in the PCOD group. Forskolin inhibited MMP-9 activity and increased TIMP-1 and progesterone secretion in both groups. Progesterone production was inversely related to the ratio of MMP-9-TIMP-1 regardless of cell origin. In this preliminary study, similar and divergent patterns have emerged in the regulation of MMP-9 and TIMP-1 in human luteinized granulosa cells. Repressing MMP-9-TIMP-1 ratio may have an important modulatory effect on progesterone secretion.

Building manned lunar base is one of the core aims of human lunar exploration project, which is also an important way to carry out the exploitation and utilization of lunar in situ resources. The most important part of manned lunar base is the design and construction of living habitation and many factors should be considered including science objective and site selection. Through investigating and research, the scientific goals of manned lunar base should be status and characteristics ascertainment of lunar available in situ resources, then developing necessary scientific experiments and utilization of lunar in situ resources by using special environment conditions of lunar surface. The site selection strategy of manned lunar base should rely on scientific goals according to special lunar surface environment and engineering capacity constraints, meanwhile, consulting the landing sites of foreign unmanned and manned lunar exploration, and choosing different typical regions of lunar surface and analyzing the landform and physiognomy, reachability, thermal environment, sunlight condition, micro meteoroids protection and utilization of in situ resources, after these steps, a logical lunar living habitation site should be confirmed. This paper brings out and compares three kinds of configurations with fabricating processes of manned lunar base, including rigid module, flexible and construction module manned lunar base. 1.The rigid habitation module is usually made by metal materials. The design and fabrication may consult the experience of space station, hence with mature technique. Because this configuration cannot be folded or deployed, which not only afford limit working and living room for astronauts, but also needs repetitious cargo transit between earth and moon for lunar base extending. 2. The flexible module habitation can be folded in fairing while launching. When deploying on moon, the configuration can be inflatable or mechanically-deployed, which means under

(Asu) E-CT is a deaminodicarba-analog of the synthetic eel-calcitonin (E-CT) that shows specific activity and the potency reasonably high in comparison with that of the most potent natural hormone. The structure of its molecule indicates that the disulphide bond in calcitonins is not essential for the biological activity but only for the maintenance of the specific conformation by forming an intramolecular bridge. The instability of calcitonins should mainly be attributed to the presence of the disulfide bond and (Asu)E-CT proved to be more stable "in vitro" than native calcitonins. The more prolonged hypocalcemic effect of E-CT and its aminosuberic analog (Asu)E-CT has been accounted for to a greater stability of and persistence at the receptor site. (Asu) E-CT has been largely studied in Japan on experimental animals and successfully used in the treatment of hypercalcemia in man. On the contrary investigations on human administration of this analog are very scarce. The present paper reports studies carried out in normal subjects and Paget's disease patients to investigate the effects of (Asu)E-CT in man in comparison with the effects of synthetic human calcitonin (H-CT) and synthetic salmon calcitonin (S-CT). Two different experimental procedures have been used: 1) rapid intravenous injection of (Asu)E-CT (80 MRC. U.) or respectively of H-CT and S-CT (100 MRC. U.) in 15 subjects (7 normals and 8 with Paget's disease); 2) slow 7 days continuous subcutaneous infusion of similar daily amounts of (Asu)E-CT, H-CT and S-CT administered by a microjet pump device in 21 subjects (7 normals and 14 with Paget's disease). The intravenous administration of (Asu)E-CT induced a rapid and persistent decrease in total plasma calcium, ionized calcium and plasma phosphate that was more evident in Paget's disease patients than in normal subjects. No clearly cut differences have been observed with the hypocalcemic and hypophosphatemic effect of H-CT and S-CT administered

Quantification of human error and common-mode failures in man-machine systems

Quantification of human performance, particularly the determination of human error, is essential for realistic assessment of overall system performance of man-machine systems. This paper presents an analysis of human errors in nuclear power plant systems when measured against common-mode failures (CMF). Human errors evaluated are improper testing, inadequate maintenance strategy, and miscalibration. The methodology presented in the paper represents a positive contribution to power plant systems availability by identifying sources of common-mode failure when operational functions are involved. It is also applicable to other complex systems such as chemical plants, aircraft and motor industries; in fact, any large man-created, man-machine system could be included

To identify the relationship and behaviour of the variables of self-control, self-efficacy and locus control in weight regulation of obese, overweight and normal weight adults. Transversal study undertaken in the Health Centre of El Coto (Gijón) from 1st April to 30th July 2015. Subjects between 18-65 years of age with a body mass index recording within the last two years. serious medical illness, eating disorders or pregnant women. Behavioural variables: self-regulation of body weight (Inventory of self-control of body weight), perceived self-efficacy in weight regulation (Inventory of perceived self-efficacy in weight regulation) and locus control in weight regulation (Inventory of locus control in weight regulation). Anthropometric variables: weight (kg) and height (m), body mass index. One hundred and six participants were included: 32 were obese, 28 overweight and 46 normal weight. Significant differences were found between the 3 study groups for total scale of self-efficacy (F=61.77; pcontrol (F=13.92; p=.019), other weighty influences of locus control (F=9.21; pcontrol (F=3.50; p=.011). The relationship between body mass index and behavioural variables of self-efficacy, self-regulation and locus control, suggests the need for healthcare professionals to include psychological factors of behaviour in any preventive action and intervention directed at weight control.

2012-01-01

The proto-oncogenic protein c-Myb is an essential regulator of hematopoiesis and is frequently deregulated in hematological diseases such as lymphoma and leukemia. To gain insight into the mechanisms underlying the aberrant expression of c-Myb in myeloid leukemia, we analyzed and compared c-myb gene transcriptional regulation using two cell lines modeling normal hematopoietic progenitor cells (HPCs) and transformed myelomonocytic blasts. We report that the transcription factors HoxA9, Meis1, Pbx1 and Pbx2 bind in vivo to the c-myb locus and maintain its expression through different mechanisms in HPCs and leukemic cells. Our analysis also points to a critical role for Pbx2 in deregulating c-myb expression in murine myeloid cells cotransformed by the cooperative activity of HoxA9 and Meis1. This effect is associated with an intronic positioning of epigenetic marks and RNA polymerase II binding in the orthologous region of a previously described alternative promoter for c-myb. Taken together, our results could provide a first hint to explain the abnormal expression of c-myb in leukemic cells

Control rooms and man-machine interface in nuclear power plants

International Nuclear Information System (INIS)

1990-08-01

The importance of man-machine interface for ensuring safe and reliable operation of nuclear power plants has always been recognized. Since the early 1970's, the concepts of operator support and human factors have been increasingly used to better define the role of control rooms. In the late 1970's, the lessons learned from experience considerably accelerated the development of recommendations and regulatory requirements governing the resources and data available to operators in nuclear power plant control rooms, and specified the expertise required to assist them in case of need. This document summarizes the steps which have been taken and are being planned around the world to improve the man-machine interface for safe and economic power generation. It intends to present to the reader useful examples on some selected control room design and man-machine interface practices for operation and surveillance of nuclear power plants. 53 refs, 94 figs, 27 tabs
