  1. Amino acid sequence and posttranslational modifications of human factor VIIa from plasma and transfected baby hamster kidney cells

    International Nuclear Information System (INIS)

    Blood coagulation factor VII is a vitamin K dependent glycoprotein which in its activated form, factor VIIa, participates in the coagulation process by activating factor X and/or factor IX in the presence of Ca2+ and tissue factor. Three types of potential posttranslational modifications exist in the human factor VIIa molecule, namely, 10 γ-carboxylated, N-terminally located glutamic acid residues, 1 β-hydroxylated aspartic acid residue, and 2 N-glycosylated asparagine residues. In the present study, the amino acid sequence and posttranslational modifications of recombinant factor VIIa as purified from the culture medium of a transfected baby hamster kidney cell line have been compared to human plasma factor VIIa. By use of HPLC, amino acid analysis, peptide mapping, and automated Edman degradation, the protein backbone of recombinant factor VIIa was found to be identical with human factor VIIa. Asparagine residues 145 and 322 were found to be fully N-glycosylated in human plasma factor VIIa. In the recombinant factor VIIa, asparagine residue 322 was fully glycosylated whereas asparagine residue 145 was only partially (approximately 66%) glycosylated. Besides minor differences in the sialic acid and fucose contents, the overall carbohydrate compositions were nearly identical in recombinant factor VIIa and human plasma factor VIIa. These results show that factor VIIa as produced in the transfected baby hamster kidney cells is very similar to human plasma factor VIIa and that this cell line thus might represent an alternative source for human factor VIIa

    Rubella virus is very sensitive to photodynamic action. When tested with 1.2 x 10{sup -5} M toluidine blue and 8 W fluorescent lamp at a fluence of 11 W/m{sup 2}, inactivation kinetics showed a linear single hit curve with a k value of 1.48 min{sup -1}. Photodynamic inactivation of rubella virus greatly enhanced recombination with a latent virus (R-virus) of baby hamster kidney BHK21 cells. In contrast, no hybrids were detected in lysates of the cells infected with either UV-treated or untreated rubella virus. Therefore, hybrid viruses were readily detected only in lysates of BHK21 cells infected with photodynamically treated rubella virus. Photodynamic damage of rubella virus genomes generated a new hybrid type (hybrid type 3) in addition to a previously described type 2 hybrid (formerly designated as HPV-RV variant). Although both of these hybrid types carry the CF antigens of rubella virus, plaque forming ability of type 3 hybrid is neutralized neither by anti-rubella serum nor by anti-latent virus serum while type 2 hybrid is neutralized by anti-latent virus serum.

    AIM: To study the baculovirus/mammalian cell system for efficient expression of functional large hepatitis delta antigen (L-HDAg).METHODS: A recombinant baculovirus expressing histidine-tagged L-HDAg (L-HDAgH) was constructed to transduce baby hamster kidney (BHK) cells by a simplified transduction protocol.RESULTS: The recombinant baculovirus transduced BHK cells with efficiencies higher than 90% as determined by flow cytometry. The expression level was significantly higher than that obtained by plasmid transfection and was further enhanced 3-fold to around 19 pg/cell by the addition of 10 mmol/L sodium butyrate. Importantly,the expressed L-HDAgH was localized to the cell nucleus and correctly isoprenylated as determined by immunofluorescence labeling and confocal microscopy.Moreover, L-HDAgH interacted with hepatitis B surface antigen to form virus-like particles.CONCLUSION: The fusion with histidine tags as well as overexpression of L-HDAgH in the baculovirus-transduced BHK cells does not impair the biological functions. Taken together, the baculovirus/mammalian cell system offers an attractive alternative for high level expression of L-HDAgH or other proteins that require extensive posttranslational modifications.

    Polyoma virus-transformed baby hamster kidney (pyBHK) cells were cultured in medium containing ({sup 32}P)orthophosphate and 105 (vol/vol) fetal bovine serum. A {sup 32}P-labeled protein with an apparent molecular mass of 97 kDa was immunoprecipitated from cell lysates with antiserum to ADP-ribosylated elongation factor 2 (EF-2). The {sup 32}P labeling of the protein was enhanced by culturing cells in medium containing 2% serum instead of 10% serum. The {sup 32}P label was completely removed from the protein by treatment with snake venom phosphodiesterase and the digestion product was identified as ({sup 32}P)AMP, indicating the protein was mono-ADP-ribosylated. HPLC analysis of tryptic peptides of the {sup 32}P-labeled 97-kDa protein and purified EF-2, which was ADP-ribosylated in vitro with diphtheria toxin fragment A and ({sup 32}P)NAD, demonstrated an identical labeled peptide in the two proteins. The data strongly suggest that EF-2 was endogenously ADP-ribosylated in pyBHK cells. Maximum incorporation of radioactivity in EF-2 occurred by 12 hr and remained constant over the subsequent 12 hr. It was estimated that 30-35% of the EF-2 was ADP-ribosylated in cells cultured in medium containing 2% serum. When {sup 32}P-labeled cultures were incubated in medium containing unlabeled phosphate, the {sup 32}P label was lost from the EF-2 within 30 min.

  5. Fibroblast receptor for cell-substratum adhesion: studies on the interaction of baby hamster kidney cells with latex beads coated by cold insoluble globulin (plasma fibronectin)

    1980-01-01

    Studies were carried out on the interactions of uncharged latex beads (0.76 micrometer) with baby hamster kidney cells. Binding of beads to the cells occurred if the beads were coated by cold insoluble globulin (CIG) (plasma fibronectin) but not if the beads were coated by bovine albumin. Bovine albumin-coated beads did not bind to the cells even in the presence of excess CIG in the incubation medium. Binding of beads occurred randomly over the entire surfaces of cells in suspension. However,...

    Baby hamster kidney (BHK21) cells are used to produce vaccines against various viral veterinary diseases, including rabies and foot-and-mouth-disease. Although particular influenza virus strains replicate efficiently in BHK21 cells the general use of these cells for influenza vaccine production is prohibited by the poor replication of most strains, including model strain A/PR/8/34 [H1N1] (PR8). We now show that in contrast to PR8, the related strain A/WSN/33 [H1N1] (WSN) replicates efficiently in BHK21 cells. This difference is determined by the haemagglutinin (HA) protein since reciprocal reassortant viruses with swapped HAs behave similarly with respect to growth on BHK21 cells as the parental virus from which their HA gene is derived. The ability or inability of six other influenza virus strains to grow on BHK21 cells appears to be similarly dependent on the nature of the HA gene since reassortant PR8 viruses containing the HA of these strains grow to similar titres as the parental virus from which the HA gene was derived. However, the growth to low titres of a seventh influenza strain was not due to the nature of the HA gene since a reassortant PR8 virus containing this HA grew efficiently on BHK21 cells. Taken together, these results suggest that the HA gene often primarily determines influenza replication efficiency on BHK21 cells but that in some strains other genes are also involved. High virus titres could be obtained with reassortant PR8 strains that contained a chimeric HA consisting of the HA1 domain of PR8 and the HA2 domain of WSN. HA1 contains most antigenic sites and is therefore important for vaccine efficacy. This method of producing the HA1 domain as fusion to a heterologous HA2 domain could possibly also be used for the production of HA1 domains of other viruses to enable the use of BHK21 cells as a generic platform for veterinary influenza vaccine production.

  7. Expression of human α2-macroglobulin cDNA in baby hamster kidney fibroblasts: Secretion of high levels of active α2-macroglobulin

    International Nuclear Information System (INIS)

    Human α2-macroglobulin (α2M) is a unique 720-kDa proteinase inhibitor with a broad specificity. Unlike most other proteinase inhibitors, it does not inhibit proteolytic activity by blocking the active site of the proteinase. During complex formation with a proteinase α2M entraps the proteinase molecule in a reaction that involves large conformational changes in α2M. The authors describe the molecular cloning of α2M cDNA from the human hepatoblastoma cell line HepG2. The cDNA was subcloned under control of the adenovirus major late promoter in a mammalian expression vector and introduced into the baby hamster kidney (BHK) cell line. Transformed clones were isolated and tested for production of human α2M with a specific enzyme-linked immunosorbent assay. Human recombinant α2M (rα2M), secreted and purified form isolated transfected BHK cell lines, was structurally and functionally compared to α2M purified from human serum. The results show that rα2M was secreted from the BHK cells as an active proteinase-binding tetramer with functional thiol esters. Cleavage reactions of rα2M with methylamine and trypsin showed that the recombinant product, which was correctly processed at the N-terminus, exhibited molecular characteristics similar to those of the human serum derived reference

    Male Syrian golden hamsters chronically exposed to diethylstilbestrol (DES) develop renal adenocarcinomas with an incidence approaching 100%. The ability of the hamster kidney to bioactivate DES was assessed using hamster kidney slices. The male hamster renal cortex has a 2- to 5-fold greater capacity to irreversibly bind ({sup 3}H)DES as compared with female hamster renal cortex and with male hamster renal medulla. Incubation of the tissue under anaerobic conditions inhibited the metabolism and irreversible binding of ({sup 3}H)DES. Gel electrophoresis analysis of covalently modified proteins revealed several radioactive peaks indicating that specific adduct formation had occurred. The cytochrome P-450 inhibitors SKF 525-A, metyrapone, carbon monoxide, butylated hydroxytoluene, and dicumarol decreased the irreversible binding of ({sup 3}H)DES to renal cortical protein by 38 to 72%.

    Chronic exposure of hamsters to chrysotile asbestos resulted in severe asbestosis in all animals and in increased mortality; concomitant exposure to cigarette smoke did not affect type or severity of asbestotic lesions. Chronic exposure to asbestos-cement dust increased the number of macrophages and ferruginous bodies. Exposure to talc baby powder caused no significant changes. Deposition of talc particles in the lungs was demonstrated by X-ray fluorescence and X-ray diffraction and by a study with neutron-activated talc. No malignant tumours were observed in any of these studies.

    Full Text Available Abstract Kidney tumors from stilbene estrogen (diethylstilbestrol-treated Syrian hamsters were screened for somatic genetic alterations by Random Amplified Polymorphic DNA-polymerase chain-reaction (RAPD-PCR fingerprinting. Fingerprints from tumor tissue were generated by single arbitrary primers and compared with fingerprints for normal tissue from the same animal, as well as normal and tumor tissues from different animals. Sixty one of the arbitrary primers amplified 365 loci that contain approximately 476 kbp of the hamster genome. Among these amplified DNA fragments, 44 loci exhibited either qualitative or quantitative differences between the tumor tissues and normal kidney tissues. RAPD-PCR loci showing decreased and increased intensities in tumor tissue DNA relative to control DNA indicate that loci have undergone allelic losses and gains, respectively, in the stilbene estrogen-induced tumor cell genome. The presence or absence of the amplified DNA fragments indicate homozygous insertions or deletions in the kidney tumor DNA compared to the age-matched normal kidney tissue DNA. Seven of 44 mutated loci also were present in the kidney tissues adjacent to tumors (free of macroscopic tumors. The presence of mutated loci in uninvolved (non-tumor surrounding tissue adjacent to tumors from stilbene estrogen-treated hamsters suggests that these mutations occurred in the early stages of carcinogenesis. The cloning and sequencing of RAPD amplified loci revealed that one mutated locus had significant sequence similarity with the hamster Cyp1A1 gene. The results show the ability of RAPD-PCR to detect and isolate, in a single step, DNA sequences representing genetic alterations in stilbene estrogen-induced cancer cells, including losses of heterozygosity, and homozygous deletion and insertion mutations. RAPD-PCR provides an alternative molecular approach for studying cancer cytogenetics in stilbene estrogen-induced tumors in humans and experimental

  14. Studies into the protein content in hamster kidney cells BHK21 infected with the fowl plague virus

    International Nuclear Information System (INIS)

    The impact of viral infection on protein synthesis has been studied in vitro. Cultures using a stable cell line, BHK21 (hamster kidney cells), are inoculated with chicken-pox virus and scores are made of 14C-lysine incorporation rate. The results indicate depression of protein synthesis, particularly marked within the first few hours after inoculation; at 5 hours the level of inrorporation into water soluble proteins is as low as about 35% of the control level, by 24 hours it is only about 19%. Distribution among 13 electrophoretic fractions of water soluble proteins is found to vary over a wide range, mobile fractions showing higher rates of amino acid incorporation while others exhibit depression or figures of the same order of magnitude as controls. It may thus be inferred that, in cell cultures, virus inoculation preferentially affects only some portion of protein synthesis. (A.B.)

    Baby Skyrmions are topological solitons in a (2+1)-dimensional field theory which resembles the Skyrme model in important respects. We apply some of the techniques and approximations commonly used in discussions of the Skyrme model to the dynamics of baby Skyrmions and directly test them against numerical simulations. Specifically we study the effect of spin on the shape of a single baby Skyrmion, the dependence of the forces between two baby Skyrmions on the baby Skyrmions` relative orientation and the forces between two baby Skyrmions when one of them is spinning.

    Plagiocephaly was diagnosed in a baby aged 4 months and brachycephaly in a baby aged 5 months. Positional or deformational plagio- or brachycephaly is characterized by changes in shape and symmetry of the cranial vault. Treatment options are conservative and may include physiotherapy and helmet therapy. During the last two decades the incidence of positional plagiocephaly has increased in the Netherlands. This increase is due to the recommendation that babies be laid on their backs in order to reduce the risk of sudden infant death syndrome. We suggest the following: in cases of positional preference of the infant, referral to a physiotherapist is indicated. In cases of unacceptable deformity of the cranium at the age 5 months, moulding helmet therapy is a possible treatment option. PMID:19857299

    Full Text Available The ichthyosis are a heterogeneous group of hereditary and acquired disorder of keratinization which affected the epidermis characterized by presence of visible scales on the skin surface in the absence of inflammation. It can occur as a disease limited to the skin or in association with abnormalities of other organ systems. Lamelar ihthyosis (LI is one of two mayor autosomal recessive ichthyosis with an incidence of approximately one in 300,000. The diagnosis is based on clinical and pathologic finding. Infection is the most common complication, while prognosis of LI is depends on severity and complication of the disease. A case of lamellar ichthyosis in 0 day Balinese female baby was reported. The skin of the body was thick, plate-like appearance, scaling on the entire body, some of the thick skin was ruptured on chest and extremities. There were eclabium on the mouth and ectropion on the eyes. Histopathology examination showed hyperkeratosis without perivascular infiltration lymphocyte. The baby was given breast feeding, antibiotic, hydrocortisone cream and olium olivarum. The prognosis of the baby is good.

    The present study was designed to investigate the potential protective effect of melatonin as an antioxidant separately or in combination with antigens (cercarial; CAP or soluble worm; SWAP) against Schistosoma mansoni infection in hamsters. Each hamster was sensitized with an initial immunization of 0.6 ml of the extracted antigen (30 μg protein/mL). After four days, a second injection of 0.4 mL was given (20 μg protein/mL). Then, each hamster was exposed to 260±20 S.mansoni cercariae followed with melatonin treatment (3.5 mg/kg) for thirty days from the 1st day of post infection. Levels of lipid peroxidation (LPO) products, catalase (CAT) activity, hepatic glutathione (GSH) and biochemical changes in the liver and kidneys functions were investigated. The results revealed a high significant increasing of LPO and decreasing of CAT and GSH in liver of infected hamsters. Biochemical observations showed severe damage in the liver enzyme activities and increasing cholesterol level in infected animals. Melatonin co-treatment with antigen to the infected-hamster attenuated the increase of LPO and restored the activity of CAT and levels of hepatic GSH. Also, the biochemical damages in the liver and kidneys functions were reduced. The present study suggests that melatonin may be useful in combating free radical-induced damage due to infection toxicity. The immunization with previous antigens resulted in a remarkable improvement on the liver enzyme activities, which were increased after infection. Thus, vaccination of hamsters with antigens (both CAP and SWAP) and melatonin treatment has more potent effect on the enhancement of antioxidant and biochemical of S.mansoni infected-hamster than each treatment separately. Immunization of the hamster with SWAP followed by melatonin was the best way among the other regime treatments to improve the biochemical and antioxidant parameters of the infected-hamsters[Current Zoology 55(2):165-172,2009].

    2016-05-01

    The shaken baby syndrome (SBS) or shaking trauma describes the occurrence of subdural hematoma, retinal hemorrhage and diffuse injury to the brain by vigorous shaking of an infant that has a poor prognosis. Rapid cranial acceleration and deceleration leads to tearing of bridging veins, retinal hemorrhages and diffuse brain injuries. In addition to clinical symptoms, such as irritability, feeding difficulties, somnolence, apathy, seizures, apnea and temperature regulation disorders, vomiting also occurs due to increased intracranial pressure. Milder forms of SBS often go undiagnosed and the number of unreported cases (grey area) is probably much higher. Up to 20 % of patients die within days or weeks due to SBS and survivors often show cognitive deficits and clinical symptoms, such as physical disabilities, impaired hearing, impaired vision up to blindness, epilepsy and mental retardation as well as a combination of these conditions; therefore, prevention is very important.

  10. Baby universes, fine tuning problems

    International Nuclear Information System (INIS)

    We review the recently popular 'theory of baby universes' put forward by Banks, Coleman and Hawking. We then derive the strong CP breaking coefficient θ-bar to be very small, in a similar manner to the derivation of the cosmological constant being zero. A solution for an old controversy concerning the entropy creation in black holes is also discussed. We finally confront the baby universe theory with random dynamics. We conclude that the theory of baby universes is so successful that the essential features are likely true and might have to go into a right theory even if with some troubles at first. (author)

    2014-12-01

    Full Text Available Colloidon baby describes a highly characteristic clinical entity in newborns encased in a yellowish translucent membrane resembling collodion. In most cases the condition either precedes the development of one of a variety of ichthyoses, the commonest of which are lamellar ichthyosis and non-bullous ichthyosiform erythroderma, or occasionally represents an initial phase of other ichthyoses such as ichthyosis vulgaris. In at least 10% of all cases of collodion baby, the condition is followed by a mild ichthyosis of lamellar type, so mild as to be considered more or less normal, so-called self-healing collodion baby or ‘lamellar ichthyosis of the newborn’. In this report we present a rare case of collodion baby in whom, after collodion membrane peeled-off, the skin retained normal appearance.

    With the machine restart and first collisions at 3.5 TeV, 2009 and 2010 were two action-packed years at the LHC. The events were a real media success, but one important result that remained well hidden was the ten births in the LHC team over the same period.

  18. Shaken baby syndrome

    International Nuclear Information System (INIS)

    Shaken baby syndrome (SBS) describes the coincidence of subdural hematoma, retinal bleeding and, disadvantageous for the prognosis, diffuse brain damage caused by powerful shaking of the infant. The clinical symptoms include irritability, difficulty with drinking, somnolence, apathy, cerebral cramp attacks, apnoea, temperature regulation disorders and vomiting due to cranial pressure. Milder symptoms of SBS are often not diagnosed and the number of unregistered cases is probably much greater. The diagnosis of SBS is made through the typical symptom constellation, but the lack of retinal bleeding does not exclude the diagnosis. Normally the infants are held by the thorax or upper arms and shaken in a sagittal direction during which the head falls backwards and forwards and is stopped abruptly at each extreme position. The injurious mechanism is considered to be caused by rotational forces which force tissue layers in the brain against each other and also lead to rupture of bridging veins between the skull and the brain. The prognosis is poor and approximately 25% of infants die of SBS within days or weeks. Approximately 75% of survivors suffer from long term damage with physical handicaps, limitations in hearing, visual disturbances up to blindness and mental disorders or combinations of these conditions. Prevention is therefore the most important aspect. (orig.)

  19. Baby Solar System

    2012-01-01

    What did our solar system look like in its infancy,...... when the planets were forming? We cannot travel back in time to take an image of the early solar system, but in principle we can have the next best thing: images of infant planetary systems around Sun-like stars with ages of 1 to 5 million years, the time we think it took for the giant planets to form. Infant exoplanetary systems are critically important because they can help us understand how our solar system fits within the context of planet formation in general. More than 80% of stars are born with gas- and dust-rich disks, and thus have the potential to form planets. Through many methods we have identified more than 760 planetary systems around middle-aged stars like the Sun, but many of these have architectures that look nothing like our solar system. Young planetary systems are important missing links between various endpoints and may help us understand how and when these differences emerge. Well-known star-forming regions in Taurus, Scorpius. and Orion contain stars that could have infant planetary systems. But these stars are much more distant than our nearest neighbors such as Alpha Centauri or Sirius, making it extremely challenging to produce clear images of systems that can reveal signs of recent planet formation, let alone reveal the planets themselves. Recently, a star with the unassuming name LkCa 15 may have given us our first detailed "baby picture" of a young planetary system similar to our solar system. Located about 450 light-years away in the Taurus starforming region. LkCa 15 has a mass comparable to the Sun (0.97 solar mass) and an age of l to 5 million years, comparable to the time at which Saturn and perhaps Jupiter formed. The star is surrounded by a gas-rich disk similar in structure to the one in our solar system from which the planets formed. With new technologies and observing strategies, we have confirmed suspicions that LkCa 15's disk harbors a young planetary system.

  5. The hamster (Mesocricetus auratus) as an experimental model of toxocariasis: histopathological, immunohistochemical, and immunoelectron microscopic findings.

    2015-03-01

    Toxocariasis is a globally distributed parasitic infection caused by the larval stage of Toxocara spp. The typical natural hosts of the parasite are dogs and cats, but humans can be infected by the larval stage of the parasite after ingesting embryonated eggs in soil or from contaminated hands or fomites. The migrating larvae are not adapted to complete their life cycle within accidental or paratenic hosts like humans and laboratory animals, respectively, but they are capable of invading viscera or other tissues where they may survive and induce disease. In order to characterize hamsters (Mesocricetus auratus) as a model for Toxocara canis infection, histopathological and immunohistochemistry procedures were used to detect pathological lesions and the distribution of toxocaral antigens in the liver, lungs, and kidneys of experimentally infected animals. We also attempted to characterize the immunological parameters of the inflammatory response and correlate them with the histopathological findings. In the kidney, a correlation between glomerular changes and antigen deposits was evaluated using immunoelectron microscopy. The hamster is an adequate model of experimental toxocariasis for short-term investigations and has a good immunological and pathological response to the infection. Lung and liver manifestations of toxocariasis in hamsters approximated those in humans and other experimental animal models. A mixed Th2 immunological response to T. canis infection was predominant. The hamster model displayed a progressive rise of anti-toxocaral antibodies with the formation of immune complexes. Circulating antigens, immunoglobulin, and complement deposits were detected in the kidney without the development of a definite immune complex nephropathy. PMID:25518818

    1986-04-01

    A black coat-color mutant with tremor was discovered in babies of 61 generations of an inbred strain APG of Syrian hamster which had been maintained in the Nippon Institute for Biological Science, Laboratory Animal Research Station. The genetical analysis by matings between four inbred strains which had different genes in the E and B loci and four mutant strains which were introduced the mutant gene into the four inbred strains and characterization were carried out on the mutant. The results obtained are summarized as follows: 1) The mutation occurred in a different locus with E and B loci. 2) The mutant was controlled by an autosomal recessive gene designated as "bt", and it was thought that both tremor and black coat-color were the pleiotropic effect of bt gene. 3) At least one E gene in the E locus was necessary for the appearance of black coat color. Therefore, the coat-color remained cream in ee (cream) hamsters showing only trembling. 4) The degree of blackness of the coat-color of EE hamsters differed from Ee ones. The former was darker than the latter. 5) The mutant may be a useful animal model for studying abnormal myelogenesis and biosynthesis of melanin. PMID:3732409

    Full Text Available The establishment of a hamster lymphoma cell line was attempted. Simple mincing and trypsinization of lymphoma tissue resulted in a high degree of cell degeneration. The ascitic tumor cells produced by intraperitoneal transplantation of lymphoma tissue gave a better result. These ascitic cells grew and were cultured successively in medium consisting of RPMI 1640 and 20% fetal calf serum. Cells were round and grew in suspension. Accelerated cell growth was observed one month after starting the culture. In the stained preparations, cells were lymphoblastic. Cells were transplantable into new-born hamsters and produced tumors, but not in young adult hamsters.

    Rocio virus (ROCV) is an encephalitic flavivirus endemic to Brazil. Experimental flavivirus infections have previously demonstrated a persistent infection and, in this study, we investigated the persistence of ROCV infection in golden hamsters (Mesocricetus auratus). The hamsters were infected intraperitoneally with 9.8 LD50/0.02 mL of ROCV and later anaesthetised and sacrificed at various time points over a 120-day period to collect of blood, urine and organ samples. The viral titres were quantified by real-time-polymerase chain reaction (qRT-PCR). The specimens were used to infect Vero cells and ROCV antigens in the cells were detected by immunefluorescence assay. The levels of antibodies were determined by the haemagglutination inhibition technique. A histopathological examination was performed on the tissues by staining with haematoxylin-eosin and detecting viral antigens by immunohistochemistry (IHC). ROCV induced a strong immune response and was pathogenic in hamsters through neuroinvasion. ROCV was recovered from Vero cells exposed to samples from the viscera, brain, blood, serum and urine and was detected by qRT-PCR in the brain, liver and blood for three months after infection. ROCV induced histopathological changes and the expression of viral antigens, which were detected by IHC in the liver, kidney, lung and brain up to four months after infection. These findings show that ROCV is pathogenic to golden hamsters and has the capacity to cause persistent infection in animals after intraperitoneal infection. PMID:22850953

  19. Properties of Syrian hamster cells transformed by human papillomavirus type 16

    International Nuclear Information System (INIS)

    Adult Syrian hamster kidney cells were transfected with a mixture of plasmids containing human papillomavirus type 16 (HPV16) E6/E7 open reading frames (ORFs), activated Ha-ras gene and neomycin resistance gene. From these cultures two lines were isolated which were oncogenic for newborn and 5-day-old but not for-3-week-old hamster. Sublines oncogenic for 3-7 week-old hamsters were derived from turn-ours formed in animals inoculated with 5 days of birth. Sublines oncogenic for 3-7-old hamsters were derived from tumours formed in animals inoculated within 5 days of birth. The cells contained HPV16 DNA in an integrated form and HPV16 transcripts. The transcript patterns in low and high oncogenicity sublines were different. Very few tumour-bearing animals possessed antibodies reactive with E6- and E7-derived synthetic peptides. On the other hand, a majority of these animals gave a positive reaction in the lymphoproliferation assay with either E6 and E7 peptides or extracts from the transformed cells. (author)

    1988-09-01

    In studies of experimental Lyme disease, a major obstacle has been the unavailability of a suitable animal model. We found that irradiated LSH/Ss Lak hamsters developed arthritis after injection of Borrelia burgdorferi in the hind paws. When nonirradiated hamsters were injected in the hind paws with B. burgdorferi, acute transient synovitis was present. A diffuse neutrophilic infiltrate involved the synovia and periarticular structures. The inflammation was associated with edema, hyperemia, and granulation tissue. Numerous spirochetes were seen in the synovial and subsynovial tissues. The histopathologic changes were enhanced in irradiated hamsters. The onset and duration of the induced swelling were dependent on the dose of radiation and the inoculum of spirochetes. Inoculation of irradiated hamsters with Formalin-killed spirochetes or medium in which B. burgdorferi had grown for 7 days failed to induce swelling. This animal model should prove useful for studies of the immune response to B. burgdorferi and the pathogenesis of Lyme arthritis.

    In vivo responses to gold nanoparticles (GNPs) vary not only according to the size, shape, surface charge, and capping agent of GNPs but also according to the animal model, the route of administration, and the exposure frequency and duration. We illustrate here the changes in some hematologic parameters, in the hepatic and renal functions, and in the histopathology of solid organs after multiple intraperitoneal injections of 18 nm GNPs in adult male Syrian golden hamsters. We scored the histopathological changes in the liver and kidneys to grade the deleterious effects. Multiple intraperitoneal injections of 18 nm GNPs in hamsters were nonlethal in the short term but resulted in macrocytosis and hypochromasia, leukocytosis, neutrophilia, lymphocytosis, and monocytosis. The hepatic and renal functions showed nonsignificant changes; however, histopathological examination showed hepatic and renal alterations ranging from mild to marked degeneration, with occasional necrosis of hepatocytes and tubular epithelium.

    Leptospirosis is caused by pathogenic spirochetes of the genus Leptospira. Humans can be infected after exposure to contaminated urine of reservoir animals, usually rodents, regarded as typical asymptomatic carriers of leptospires. In contrast, accidental hosts may present an acute form of leptospirosis with a range of clinical symptoms including the development of Acute Kidney Injury (AKI). Chronic Kidney Disease (CKD) is considered as a possible AKI-residual sequela but little is known about the renal pathophysiology consequent to leptospirosis infection. Herein, we studied the renal morphological alterations in relation with the regulation of inflammatory cytokines and chemokines, comparing two experimental models of chronic leptospirosis, the golden Syrian hamster that survived the infection, becoming carrier of virulent leptospires, and the OF1 mouse, a usual reservoir of the bacteria. Animals were monitored until 28 days after injection with a virulent L. borgpetersenii serogroup Ballum to assess chronic infection. Hamsters developed morphological alterations in the kidneys with tubulointerstitial nephritis and fibrosis. Grading of lesions revealed higher scores in hamsters compared to the slight alterations observed in the mouse kidneys, irrespective of the bacterial load. Interestingly, pro-fibrotic TGF-β was downregulated in mouse kidneys. Moreover, cytokines IL-1β and IL-10, and chemokines MIP-1α/CCL3 and IP-10/CXCL-10 were significantly upregulated in hamster kidneys compared to mice. These results suggest a possible maintenance of inflammatory processes in the hamster kidneys with the infiltration of inflammatory cells in response to bacterial carriage, resulting in alterations of renal tissues. In contrast, lower expression levels in mouse kidneys indicated a better regulation of the inflammatory response and possible resolution processes likely related to resistance mechanisms.

  11. Pharmacokinetics and tissue distribution of Antimony after multiple intramuscular administrations in the Hamster

    International Nuclear Information System (INIS)

    The fate of pentavalent antimony (Sb) in different tissues in the body after intramuscular administration is of great interest for the future study of Sb therapy in different sitting. Pharmacokinetics and tissue distribution of antimony (Sb) were studied in the hamster after daily dose of sodium stibogluconate equivalent to 120 mg kg of Sb, administered intramuscularly for two weeks. Liver, spleen, heart, kidney and skin tissues were isolated after blood collection at the specified time. Antimony was measured in these tissues after suitable treatment, ashing and processing, by flame less atomic absorption spectrophotometry. The concentration of Sb time profile in blood showed a linear raid decline with elimination half life (tz1/2) of 1.7h. The concentration of drug (ug/gm) declined in a biphasic manner from almost all tissues. However, the concentrations of Sb were declined in slower fashion from the hamster tissues than from the blood. The maximum concentration of Sb was determined in the kidney tissues (3416+-631ug/gm) while the lowest concentration was in the spleen (209+-187ug/gm). The maximum concentration of Sb in the kidney (ug/gm) was more than 25 fold higher than that measured from blood (ug/ml). The AUC of Sb in the studied tissues was in this rank: kidney>liver>skin>spleen>heart>blood. Surprisingly, the heart, spleen and liver showed a similar t1/2 of 5.2-6.2h while the kidney and skin had a t1/2 of about 3h. Therefore, disposition of Sb seems to kinetically follow multicompartmental compartmental model. The kidneys got the highest concentration of drug which may lead to nephrotoxicity on long term therapy. (author)

  14. Baby universes in string theory

    International Nuclear Information System (INIS)

    We argue that the holographic description of four-dimensional Bogomol'nyi-Prasad-Sommerfield black holes naturally includes multicenter solutions. This suggests that the holographic dual to the gauge theory is not a single AdS2xS2 but a coherent ensemble of them. We verify this in a particular class of examples, where the two-dimensional Yang-Mills theory gives a holographic description of the black holes obtained by branes wrapping Calabi-Yau cycles. Using the free fermionic formulation, we show that O(e-N) nonperturbative effects entangle the two Fermi surfaces. In an Euclidean description, the wave function of the multicenter black holes gets mapped to the Hartle-Hawking wave function of baby universes. This provides a concrete realization, within string theory, of effects that can be interpreted as the creation of baby universes. We find that, at least in the case we study, the baby universes do not lead to a loss of quantum coherence, in accord with general arguments

    Adenoviral infection is a serious human pathology leading to respiratory, gastrointestinal and ocular disorders and epidemic outbreaks, especially in children's groups. Here we present the results from an investigation of anti- adenoviral effect of 6-azacytidine (6-AC) both in vitro and in vivo. The selectivity index of 6-AC for adenovirus type 5 in HEp-2 cells was 374, the 50% effective concentration was 0.5 mg/ml. For in vivo investigations we developed a model of disseminated adenoviral infection in newborn Syrian hamsters. The infectious virus was recovered from the liver, kidney, lungs and heart. Application of 6-AC led to a reduced period of the virus presence (7 days in the liver and 4 days in the kidney and heart) and lowered virus titers on day 3 post-inoculation (p.i.) (liver - 2.7 and 4.1, heart - 0 and 3.2, kidney - 0 and 2.4 log(10 )CPD(50)/mg tissue weight, in the presence and absence of 6-AC, respectively). Application of 6-AC to newborn Syrian hamsters led to partial destruction of their splenocytes. The results obtained suggest that 6-AC or 6-ACbased drugs with lower toxicity or applied topically may be suitable for therapy and prevention of adenoviral infection in humans. PMID:17309850

  17. Kinetics of Leptospira interrogans infection in hamsters after intradermal and subcutaneous challenge.

    Full Text Available Leptospirosis is a zoonosis caused by highly motile, helically shaped bacteria that penetrate the skin and mucous membranes through lesions or abrasions, and rapidly disseminate throughout the body. Although the intraperitoneal route of infection is widely used to experimentally inoculate hamsters, this challenge route does not represent a natural route of infection.Here we describe the kinetics of disease and infection in hamster model of leptospirosis after subcutaneous and intradermal inoculation of Leptospira interrogans serovar Copenhageni, strain Fiocruz L1-130. Histopathologic changes in and around the kidney, including glomerular and tubular damage and interstitial inflammatory changes, began on day 5, and preceded deterioration in renal function as measured by serum creatinine. Weight loss, hemoconcentration, increased absolute neutrophil counts (ANC in the blood and hepatic dysfunction were first noted on day 6. Vascular endothelial growth factor, a serum marker of sepsis severity, became elevated during the later stages of infection. The burden of infection, as measured by quantitative PCR, was highest in the kidney and peaked on day 5 after intradermal challenge and on day 6 after subcutaneous challenge. Compared to subcutaneous challenge, intradermal challenge resulted in a lower burden of infection in both the kidney and liver on day 6, lower ANC and less weight loss on day 7.The intradermal and subcutaneous challenge routes result in significant differences in the kinetics of dissemination and disease after challenge with L. interrogans serovar Copenhageni strain Fiocruz L1-130 at an experimental dose of 2×106 leptospires. These results provide new information regarding infection kinetics in the hamster model of leptospirosis.

    The authors studied the histopathologic evolution of arthritis in nonirradiated and irradiated hamsters infected with Borrelia burgdorferi. Nonirradiated hamsters injected in the hind paws with B. burgdorferi developed an acute inflammatory reaction involving the synovium, periarticular soft tissues, and dermis. This acute inflammatory reaction was short-lived and was replaced by a mild chronic synovitis as the number of detectable spirochetes in the synovium, periarticular soft tissues, and perineurovascular areas diminished. Exposing hamsters to radiation before inoculation with B. burgdorferi exacerbated and prolonged the acute inflammatory phase. Spirochetes also persisted longer in the periarticular soft tissues. A major histopathologic finding was destructive and erosive bone changes of the hind paws, which resulted in deformation of the joints. These studies should be helpful in defining the immune mechanism participating in the onset, progression, and resolution of Lyme arthritis.

    Generation of new neurons from adult neural stem cells occurs in the dentate gyrus (DG) of the hippocampus and the lateral walls of the lateral ventricles. In this article, we study the neurogenesis that takes place during the hibernation of the Syrian hamster (Mesocricetus auratus). Using a variety of standard neurogenesis markers and 5-bromo-2-deoxyuridine (BrdU) incorporation, we describe a preferential decrease in the proliferation of newborn neurons in the subventricular zone (SVZ) of the hibernating hamsters (torpor) rather than in the hippocampus. Furthermore, we demonstrate that the proliferative capacity is recovered after 3-4days of torpor when arousal is triggered under natural conditions (i.e., not artificially provoked). In addition, we show that tau3R, a tau isoform with three microtubule-binding domains, is a suitable marker to study neurogenesis both in the SVZ and subgranular zone (SGZ) of the Syrian hamster brain.

    To determine the optimal conditions for in vitro spermatozoa vitality, human and hamster spermatozoa were incubated at 37 degrees C in T6 medium supplemented with different biologic fluids (10% v/v). The fluids tested were human serum (HUS), hamster serum (HAS), and human follicular fluid (HUF). After incubation the spermatozoa were investigated for their qualitative and quantitative motility. Human spermatozoa maintained a good vitality in all fluids tested (approximately 25% motility after 18-h incubation). The hamster spermatozoa had after an incubation of 4 h a motility of 28.4% in HUS, 14.2% in HAS, and 2.2% in HUF. The quality of the motility was also extremely low in HUF, whereas it was adequate in HUS and in HAS. The presence of species-specific substances in mammalian follicular fluid is discussed.

    The BIO14.6 hamster is a widely used model for autosomal recessive cardiomyopathy. These animals die prematurely from progressive myocardial necrosis and heart failure. The primary genetic defect leading to the cardiomyopathy is still unknown. Recently, a genetic linkage map localized the cardiomyopathy locus on hamster chromosome 9qa2.1-b1, excluding several candidate genes. We now demonstrate that the cardiomyopathy results from a mutation in the delta-sarcoglycan gene that maps to the disease locus. This mutation was completely coincident with the disease in backcross and F2 pedigrees. This constitutes the first animal model identified for human sarcoglycan disorders. PMID:9097966

    Full Text Available Background. To propose hypovolemic shock as a possible explanation for the failure to resuscitate some babies after shoulder dystocia and to suggest a change in clinical practice. Case Presentation. Two cases are presented in which severe shoulder dystocia was resolved within five minutes. Both babies were born without a heartbeat. Despite standard resuscitation by expert neonatologists, no heartbeat was obtained until volume resuscitation was started, at 25 minutes in the first case and 11 minutes in the second. After volume resuscitation circulation was restored, there was profound brain damage and the babies died. Conclusion. Unsuspected hypovolemic shock may explain some cases of failed resuscitation after shoulder dystocia. This may require a change in clinical practice. Rather than immediately clamping the cord after the baby is delivered, it is proposed that (1 the obstetrician delay cord clamping to allow autotransfusion of the baby from the placenta and (2 the neonatal resuscitators give volume much sooner.

    International Nuclear Information System (INIS)

    To determine pulmonary deposition, translocation and clearance of inhaled talc, 10-wk-old hamsters received a single 2-hr nose-only exposure to neutron activated talc. Over a period of 4 months, the hamsters were killed in groups of four. Lungs liver, kidneys, ovaries, skinned carcass and 2-day and 4-day excreta were collected for γ-ray analysis. The isotope 60Co was used to calculate the quantity of talc in all samples; in addition, the isotope 46Sc was used in a number of samples to check the validity of 60Co as a tracer for talc. From 20 to 80 μg talc, an estimated 6 to 8% of the inhaled quantity, was deposited in the alveoli. The biological half-life of the talc deposited in the alveoli was 7 to 10 days. Alveolar clearance was essentially complete 4 months after exposure. No translocation of talc to liver, kidneys, ovaries or other parts of the body was found. Several hundred micrograms of talc were found in the faecal samples. Results of a leaching study to be described elsewhere suggest that the picogram quantities of 60Co found in the urine probably represented leached 60Co absorbed in the gastro-intestinal tract.

  20. Oxytocin inhibits aggression in female Syrian hamsters.

    Science.gov (United States)

    Harmon, A C; Huhman, K L; Moore, T O; Albers, H E

    2002-12-01

    Dominant subordinate relationships are formed as the result of social conflict and are maintained at least in part by communication. At this time, little is known about the neural mechanisms that are responsible for coordinating the social behaviours (e.g. aggression) that occur in association with the formation and maintenance of these relationships. The purpose of the present study was to investigate the role of oxytocin (OXT) within the medial preoptic anterior hypothalamic continuum (MPOA-AH) in the control of aggression in female hamsters. OXT injected into the MPOA-AH immediately before testing significantly reduced the duration of aggression in a dose-dependent manner. Injection of an OXT antagonist 30 min before testing significantly increased the duration of aggression. In contrast, the duration of aggression was not altered when hamsters were tested either 30 min after injection of OXT or immediately following injection of an OXT-antagonist. These data support the hypothesis that OXT release within the MPOA-AH regulates social behaviours important in the formation and maintenance of dominant subordinate relationships in female hamsters.

    The results of a previous study demonstrated that prednisolone enhanced cholangiocarcinogenesis. Therefore, to clarify molecular changes during immunosuppressive cholangiocarcinogenesis, Syrian hamsters were divided into 8 groups: uninfected controls; immunosuppressed Syrian hamsters using prednisolone (P); normal Syrian hamsters administered N-nitrosodimethylamine (ND); immunosuppressed Syrian hamsters administered N-nitrosodimethylamine (NDis); normal Syrian hamsters infected with Opisthorchis viverrini (OV); immunosuppressed Syrian hamsters infected with O. viverrini (OVis); normal Syrian hamsters infected with O. viverrini and administered N-nitrosodimethylamine (CCA); and immunosuppressed Syrian hamsters infected with O. viverrini and administered N-nitrosodimethylamine (CCAis). Syrian hamster livers were used for analysis of tumor-related gene expression and immunohistochemistry through cytokeratin 19 (CK19) and proliferating cell nuclear antigen (PCNA) staining. The tumor-related gene expression results show that CCAis groups at all time points exhibited upregulation of COX-2, IL-6, SOD1, CAT and iNOS and downregulation of p53, which correlated with the predominant expression of CK19 and PCNA in liver tissue. These results suggest that prednisolone enhances cholangiocarcinoma development, which was confirmed by molecular changes. PMID:23645518

    Qadeer, Imrana

    2010-01-01

    New legislation can be oppressive for a significant population depending upon the politics of its drafters. The current upsurge of the surrogacy trade in India, and the label of a "win-win" situation that it has acquired, points towards an unfettered commercialisation of assisted reproductive technology and the practice of surrogacy that is blinding its middle class users as well as providers, policy makers and law makers, and charging an imagination that is already caught up in spiralling consumerism. This paper analyses the Draft Assisted Reproductive Technology (Regulation) Bill and Rules, 2008, in the Indian socioeconomic context. It identifies the interests of the affected women, and examines the contradictions of the proposed Bill with their interests, as well as with current health and population policies, confining itself to the handling of surrogacy and not the entire content of the Bill. The bases of the analytical perspective used are: the context of poverty and the health needs of the Indian population; the need to locate surrogacy services within the overall public health service context and its epidemiological basis; the need to restrain direct human experimentation for the advancement of any technology; the use of safer methods; and, finally, the rights of surrogate mothers and their babies, in India, as opposed to the compulsion or dynamics of the medical market and reproductive tourism.

  4. Baby boom generation at the retirement onset

    Directory of Open Access Journals (Sweden)

    Stojilković Jelena

    2010-01-01

    Full Text Available Sudden increase in the number of live births after the Second World War due to an increase in fertility rates has led to the formation of cohorts with specific characteristics or baby boom generation. This generation is unique in the history of the demographic phenomenon that has affected and affects the functioning of many segments of society. The aim of this paper is to assess structure of baby boomers who are few years away from retirement, using demographic data. Impact of baby boomer age structure of current and future retirees is described with a graphical display of current and projected age pyramid of baby boomers. Demographic pattern that women live longer than men is evident in the projected pyramid. In addition, the number of baby boomers will lead to a "younger" old population. The imbalance in the number of men and women pensioners, as well as older cohorts of women and female baby boomers was analyzed. As a result, an increasing trend of women's age pensioners who are members of the baby boom generation was clearly observed, which is opposite to the older cohort of women who often were family pensioners. Different circumstances and conditions in which female boomers lived and worked will form a new "pension model" because they will gain their benefits as well as men, for the first time in significant number, unlike their mothers, which gained the right to retire after they become widows. Number of women age pensioners is getting greater comparing to men, as the result of changes in the economic activities of women in the last half of the 20th century. When baby boomers retire and exit the working population, this will create a vacuum, because the numerically smaller generations will enter working population, while the sudden and very shortly, the number of population older than 60 or 65 will increase, most of them will likely to acquire the right to a pension. It is undeniable that baby boomers had impact on demographic structure

  5. What is my Baby Like? Representations Concerning the Baby in the Third Trimester of Pregnancy

    Directory of Open Access Journals (Sweden)

    Marta Pedreira

    2015-11-01

    Full Text Available AimTo investigate if during the third trimester of pregnancy fantasies emerge in the baby representations based on the information that pregnant women have on their real babies through ultrasound techniques.MethodA qualitative, descriptive and exploratory research based on a sample of 30 pregnant Portuguese women, whose average age is 32 years old, was developed. A socio-demographic questionnaire and a semi-directive interview entitled "Interview of Maternal Representations During Pregnancy – Revised Version" (IRMAG-R, Ammaniti & Tambelli, 2010 were employed.ResultsBaby representations are immersed in a fantasy dimension, which means that the imaginary baby is quite present in this phase of pregnancy. Pregnant women mainly attribute psychological characteristics to the babies, rather than physical characteristics. Regardless of the type of characteristics analysed, the preference for these characteristics emerges based on their wishes. Secondly, characteristics of the parents may also emerge. Fetal movements and information from ultrasound have no significant influence on the characterization of the baby.ConclusionDespite the development of ultrasound techniques, the imaginary baby defines parents representations about the baby on the third trimester of pregnancy. Consequently, a new understanding of how pregnant women experience the transition to the postnatal phase has to be considered.

  8. Baby factories taint surrogacy in Nigeria.

    2016-01-01

    The practice of reproductive medicine in Nigeria is facing new challenges with the proliferation of 'baby factories'. Baby factories are buildings, hospitals or orphanages that have been converted into places for young girls and women to give birth to children for sale on the black market, often to infertile couples, or into trafficking rings. This practice illegally provides outcomes (children) similar to surrogacy. While surrogacy has not been well accepted in this environment, the proliferation of baby factories further threatens its acceptance. The involvement of medical and allied health workers in the operation of baby factories raises ethical concerns. The lack of a properly defined legal framework and code of practice for surrogacy makes it difficult to prosecute baby factory owners, especially when they are health workers claiming to be providing services to clients. In this environment, surrogacy and other assisted reproductive techniques urgently require regulation in order to define when ethico-legal lines have been crossed in providing surrogacy or surrogacy-like services.

  9. Neutron radiography by using JSW baby cyclotron

    International Nuclear Information System (INIS)

    At present, JSW baby cyclotrons are mostly used for the production of the radioisotopes for medical use. The attempt to use this baby cyclotron for neutron radiography began already in 1981. The feasibility of the neutron radiography for the explosives in metallic cases which are used for H1 rockets was investigated. In 1983, it was shown that the neutron radiography by using the baby cyclotron in Muroran Works, Japan Steel Works, Ltd. was able to be carried out as a routine work. Since then, the nondestructive inspection by neutron radiography has been performed for rocket pyrotechnic articles, and contributed to heighten their reliability. Further, the radiography by using fast neutrons was developed and put to practical use for recent large H2 rockets. The JSW baby cyclotron BC 168 which has been used for neutron radiography can accelerate 16 MeV protons or 8 MeV deuterons up to 50 μA. The principle of thermal neutron radiography is the generation of fast neutrons by irradiating a Be target with the proton beam accelerated by a baby cyclotron, the moderation of the fast neutrons, the formation of the thermal neutron flux of uniform distribution with a collimator, the thermal neutron flux hitting the Gd plate in a film cassette through an object, and the exposure of an X-ray film to electrons from the Gd plate. Fast neutron radiography apparatus, and commercial neutron radiography are described. (K.I.)

  10. Radiation-induced anorexia in Syrian hamsters

    International Nuclear Information System (INIS)

    The recovery of Syrian hamsters after split dose application (interval 11 days) was studied on the basis of the weight response and of food uptake. Two periods of weight loss and anorexia can be distinguished, an early one immediately after irradiation and a secondary one 6-10 days later. The secondary response is a function of the radiation dose and allows to distinguish survivors from non-survivors, since it is much more pronounced and longerlasting in the latter than in the former. The first response appears not to be influenced by a previous conditioning irradiation. (orig.)

  15. Baby Skyrme models without a potential term

    CERN Document Server

    Ashcroft, Jennifer; Krusch, Steffen

    2015-01-01

    We develop a one-parameter family of static baby Skyrme models that do not require a potential term to admit topological solitons. This is a novel property as all currently known baby Skyrme models must contain a potential term in order to have stable soliton solutions, though the Skyrme model does not require this. Our new models satisfy an energy bound that is linear in terms of the topological charge and can be saturated in an extreme limit. They also satisfy a virial theorem that is shared by the Skyrme model. We calculate the solitons of our new models numerically and observe that their form depends significantly on the choice of parameter. In one extreme, we find compactons whilst at the other there is a scale invariant model in which solitons can be obtained exactly as solutions to a Bogomolny equation. We provide an initial investigation into these solitons and compare them with the baby Skyrmions of other models.

  16. Dementia risk factors for Australian baby boomers

    Directory of Open Access Journals (Sweden)

    Peter K. Panegyres

    2010-07-01

    Full Text Available Baby boomers are individuals born in the years 1946 to 1965. The objective of this paper was to define the risk factors for dementia and Alzheimer’s disease (AD and their relevance to Australian baby boomers, with the aim of providing evidence-based guidelines for dementia prevention. A series of PubMed searches (1994-2010 were conducted with relevant key words. Data was included from the Australian Bureau of Statistics (ABS in relation to baby boomers in Australia. Article titles and abstracts were assessed by two reviewers for inclusion. Searches through ABS revealed no specific study on baby boomers at a national level; information was only available for Western Australia, South Australia and Queensland. A number of genetic and non-genetic risk factors for dementia were identified most of which remain controversial and require further study. We did not identify significant differences in the prevalence and incidence of dementia in those under 65 years in Queensland, South Australia and Western Australia. There were no correlations of risk factors and dementia between the Australian states. Modification of risk factors has not been proven to reduce the incidence and prevalence of dementia and AD in baby boomers. Nevertheless, on available evidence, we recommend: i active management of cardiovascular risk factors such as hypertension; ii the encouragement of a healthy lifestyle (eg, weight reduction, exercise as offering the best pathways to reduce the emerging dementia risk for baby boomers. The implications are that activities promoting a healthy heart might lead to a healthy brain and help to prevent dementia.

  17. VTR module: weaning foods for baby.

    Science.gov (United States)

    1993-01-01

    Weaning should start when the baby turns 4 months old. At this stage (4 to 6 months), milk is no longer enough. Parents should introduce new foods which can meet the fast-increasing nutrition needs of the child. Among the latest materials produced by the Video Radio Production Division of the Nutrition Center of the Philippines is a VTR training module entitled "Karagdagang Pagkain ni Baby" (Weaning Foods for Baby), designed to strengthen this important aspect of child care. Specifically, the module seeks to encourage parents to introduce foods in addition to breastmilk to their 4 to 6 month old children and to start giving them "complete" meals from 6 months onward. It provides suggestions on the kinds of foods or food combinations to give to the baby and encourages home food production (backyard gardening, poultry-raising etc) to supply food requirements of growing children. Contents of the module include how-to's on weaning food preparation (mashing, straining, flaking, chopping, scraping, etc), prescriptions on the kinds and amounts of foods for babies; and food combinations (porridge or rice and a viand from the 3 basic food groups: energy-giving, body building and regulating). For instance, at 4 months old, the baby may be given lugao (porridge), soup and fruits; at 5 months, eggs, vegetables and beans; at 6 months, fish/meat, oil or gata (coconut oil). With a running time of 18 minutes, the module uses computer graphics to highlight food items, recommended amounts, and age group requirements in the text, and applies digital multi-effects to ensure smooth traditions.

    Foreign workers are a growing phenomenom in the Federal Republic of Germany. Every 6th baby born in the country is of foreign extract, and considering the adverse circumstances of many foreigners in the country, the timing of the baby's birth is probably unplanned. PRO Familia is a family planning organization concerned with the plight of foreigners in the country. Although the organization's activities in this field have been limited to foreign language pulbications (concerning contraceptive methods) and radio broadcasting, it is making concerted efforts to include foreigners in their family planning services.

    Full Text Available Hamster, a hibernating animal, is an important experimental model in research on the influence of hypothermia on different physiological processes. A simple procedure for cultivation and identification of hamster hematopoetic stem cells (HSC and hematopoetic progenitor cells (HPC is a premise for a successful investigation upon hypothermia effects on hematopoiesis. The aim of this work was to evaluate the utilization of commercially available methylcellulose media (MC and recombinant mouse and human cytokines for hamster HSC and HPC assays, in order to enable further studies on these cells. Hamster bone marrow mononuclear cells (BMMNC were plated in MC containing cytokines that support mouse or human HPC growth. Also, BMMNC were resuspended in cytokine supplemented liquid media and incubated for 5 weeks with a four day monitoring of viable cell number. We demonstrated that hamster hematopoietic progenitor cells committed for erythroid lineage and myeloid lineage successfully formed recognizable colonies in both mouse and human MC, while multipotent progenitor cells formed colonies only in mouse MC. We also defined conditions for the evaluation of hamster HSC activity in liquid cultures, based on continuous 5 weeks HSC proliferation. The obtained results verify the utilization of mouse specific MC for further research on hamster HPC biology during hypothermia.

  2. Assessment of the teratogenicity of ammonium vanadate using Syrian golden hamsters

    Vanadium is a ubiquitous trace metal present in most plant and animal tissues. Its presence as a porphyrin in plant tissue results in accumulation of relatively high concentrations of vanadium in fossil fuels. The exposure of pregnant Syrian golden hamsters to ammonium vanadate from days 5 through 10 of gestation resulted in a statistically significant increase in skeletal anomalies and a decrease in the male:female fetal sex ratio. Skeletal anomalies included micrognathia, supernumerary ribs, and alterations in sternebral ossification. Although not statistically significant, external anomalies included meningocoele, one fetus with multiple anomalies, and the presence of a molar pregnancy. Soft tissue anomalies did not differ significantly among groups but included hydronephrosis/hydroureter and kidney dysplasia. The small numbers of malformed offspring and the lack of a clear-cut dose-response did not allow a definitive assessment of the teratogenicity of ammonium vanadate.

    Djungarian hamsters were examined for the susceptibility to Neospora caninum infection. After 29 Djungarian hamsters were intraperitoneally inoculated with 5 x 10(6) N. caninum tachyzoites of JPA1 strain, some animals showed symptoms such as ataxia, and many tissue cysts were detected in the brain and a cyst in the muscular tunics of stomach. Especially, more than 100 cysts per head were observed after 5 weeks post inoculation. It is suggested that the Djungarian hamster is a model useful to examine neosporosis. PMID:12679575

    Daily activity rhythms are nearly universal among animals and their specific pattern is an adaptation of each species to its ecological niche. Owing to the extremely consistent nocturnal patterns of activity shown by golden hamsters (Mesocricetus auratus) in the laboratory, this species is a prime model for studying the mechanisms controlling circadian rhythms. In contrast to laboratory data, we discovered that female hamsters in the wild were almost exclusively diurnal. These results raise many questions about the ecological variables that shape the activity patterns in golden hamsters and the differences between laboratory and field results. PMID:18397863

    1997-09-01

    The hamster cheek pouch is a much used but incompletely understood experimental model. In particular, the cheek pouch epithelial lipids, which are important for permeability barrier function as well as other aspects of epithelial biology, have not been completely characterized. In the present study, the complete lipid class composition has been determined by thin-layer chromatography in conjunction with photodensitometry. The major lipid classes were phospholipids, free sterols, and ceramides. Minor amounts of monohexosylceramides, sterol esters, fatty acids, and triglycerides were also present. Significant amounts of covalently bound omega-hydroxyceramide was also detected. Transmission electron micrographs reveal extensive, largely paired, lipid bilayers in the intercellular spaces of the stratum corneum. PMID:9307937

    If a female mates with a male of a closely related species, her fitness is likely to decline. Consequently, females may develop behavioral mechanisms to avoid mating with heterospecific males. In some species, one such mechanism is for adult females to learn to discriminate against heterospecific males after exposure to such males. We have previously shown that adult, female Syrian hamsters (Mesocricetus auratus) learn to discriminate against male Turkish hamsters (Mesocricetus brandti) after...

  3. Fasting-induced daily torpor in desert hamsters (Phodopus roborovskii).

    Chi, Qing-Sheng; Wan, Xin-Rong; Geiser, Fritz; Wang, De-Hua

    2016-09-01

    Daily torpor is frequently expressed in small rodents when facing energetically unfavorable ambient conditions. Desert hamsters (Phodopus roborovskii, ~20g) appear to be an exception as they have been described as homeothermic. However, we hypothesized that they can use torpor because we observed reversible decreases of body temperature (Tb) in fasted hamsters. To test this hypothesis we (i) randomly exposed fasted summer-acclimated hamsters to ambient temperatures (Tas) ranging from 5 to 30°C or (ii) supplied them with different rations of food at Ta 23°C. All desert hamsters showed heterothermy with the lowest mean Tb of 31.4±1.9°C (minimum, 29.0°C) and 31.8±2.0°C (minimum, 29.0°C) when fasted at Ta of 23°C and 19°C, respectively. Below Ta 19°C, the lowest Tb and metabolic rate increased and the proportion of hamsters using heterothermy declined. At Ta 5°C, nearly all hamsters remained normothermic by increasing heat production, suggesting that the heterothermy only occurs in moderately cold conditions, perhaps to avoid freezing at extremely low Tas. During heterothermy, Tbs below 31°C with metabolic rates below 25% of those during normothermia were detected in four individuals at Ta of 19°C and 23°C. Consequently, by definition, our observations confirm that fasted desert hamsters are capable of shallow daily torpor. The negative correlation between the lowest Tbs and amount of food supply shows that heterothermy was mainly triggered by food shortage. Our data indicate that summer-acclimated desert hamsters can express fasting-induced shallow daily torpor, which may be of significance for energy conservation and survival in the wild.

    Abstract Background Changes in photoperiod and ambient temperature trigger seasonal adaptations in the physiology and behaviour of many species, including the Djungarian hamster. Exposure of the hamsters to a short photoperiod and low ambient temperature leads to a reduction of the polyphasic distribution of sleep and waking over the light and dark period. In contrast, a long photoperiod enhances the daily sleep-wake amplitude leading to a decline of slow-wave activity in NREM sleep within th...

    2010-12-01

    Full Text Available Abstract Background There is evidence that exposure to passive smoking in general, and in babies in particular, is an important cause of morbimortality. Passive smoking is related to an increased risk of pediatric diseases such as sudden death syndrome, acute respiratory diseases, worsening of asthma, acute-chronic middle ear disease and slowing of lung growth. The objective of this article is to describe the BIBE study protocol. The BIBE study aims to determine the effectiveness of a brief intervention within the context of Primary Care, directed to mothers and fathers that smoke, in order to reduce the exposure of babies to passive smoking (ETS. Methods/Design Cluster randomized field trial (control and intervention group, multicentric and open. Subject: Fathers and/or mothers who are smokers and their babies (under 18 months that attend pediatric services in Primary Care in Catalonia. The measurements will be taken at three points in time, in each of the fathers and/or mothers who respond to a questionnaire regarding their baby's clinical background and characteristics of the baby's exposure, together with variables related to the parents' tobacco consumption. A hair sample of the baby will be taken at the beginning of the study and at six months after the initial visit (biological determination of nicotine. The intervention group will apply a brief intervention in passive smoking after specific training and the control group will apply the habitual care. Discussion Exposure to ETS is an avoidable factor related to infant morbimortality. Interventions to reduce exposure to ETS in babies are potentially beneficial for their health. The BIBE study evaluates an intervention to reduce exposure to ETS that takes advantage of pediatric visits. Interventions in the form of advice, conducted by pediatric professionals, are an excellent opportunity for prevention and protection of infants against the harmful effects of ETS.

  14. Copulatory and agonistic behavior in Syrian hamsters following social defeat.

    Science.gov (United States)

    Jeffress, Elizabeth C; Huhman, Kim L

    2013-01-01

    Syrian hamsters are highly aggressive animals that reliably defend their home territory. After social defeat, however, hamsters no longer defend their home cage but instead display submissive and defensive behavior toward an intruder, a response that we have termed conditioned defeat. Plasma testosterone is significantly reduced in Syrian hamsters following repeated defeat suggesting that social defeat might also impair copulatory behavior. The present study aimed to determine whether copulatory behavior in male Syrian hamsters is suppressed following repeated social defeats and additionally whether exposure to a hormone-primed stimulus female after social defeat reduces the behavioral response to defeat. Hamsters were paired with an aggressive opponent for one or nine defeats using a resident-intruder model, while controls were placed into the empty cage of a resident aggressor. On the day after the last treatment, half of the hamsters were paired with a receptive female for 10 min. There were no significant differences in the copulatory behavior of defeated versus non-defeated hamsters, and the opportunity to copulate had no effect on subsequent conditioned defeat testing, as defeated animals displayed significantly more submissive behavior than did non-defeated animals. The current data suggest that conditioned defeat is not necessarily a maladaptive response to social stress, at least in terms of reproductive behavior, but may instead represent a viable behavioral strategy adopted by losing animals following social defeat. Further, these data indicate that conditioned defeat is relatively persistent and stable, as the opportunity to copulate does not reduce the subsequent display of submissive behavior. PMID:23382023

  12. DESIGN OF A PORTABLE AND ATTACHABLE BABY COT

    Directory of Open Access Journals (Sweden)

    SOWAH BORIS NII-AKO

    2013-05-01

    Full Text Available To solve congestion problems facing many hospitals in developing countries, baby cots are being eliminated and mothers are made to sleep on the same bed with their new-born babies; a practice known as co-sleeping. The work presented here seeks to reduce risks of Sudden Infant Death Syndrome (SIDS and suffocation associated with co-sleeping by employing the formal engineering design process to develop a portable, safe and cost effective baby cot. The cot is attachable to the mother’s bed, has four movement restrictors to regulate the movement of the baby within a given range and a hard surface mattress to ensure the safety of the baby. There are ventilation ports provided to keep the temperature within the cot comfortable. The design can be modified to be used by older babies and may be mounted on a collapsible stand where space limitations are not critical.

  13. Transplacental and lactational exposure to mercury in hamster pups after maternal administration of methyl mercury in late gestation

    International Nuclear Information System (INIS)

    Pregnant Syrian golden hamsters were given a single oral dose of 203Hg-labelled methyl mercury (MehG), 1.6 μmol/kg body weight, on day 12 of gestation. The uptake, retention and tissue distribution of 203Hg in the dams and pups was studied by γ-counting during the following three weeks. The average transplacental transfer of 203Hg was 1.1% of the administered dose per pup, corresponding to 11% of the administered dose to a whole litter. This was considerably more than in our previous studies when the dams were treated on gestational day 2 (1.3%) or 9 (4.6%). The amount of 203Hg transferred to each pup in utero was independent of the litter size. The average additional transfer of 203Hg to a litter via milk was 1.7% of the administered dose. In the pups, the content of 203Hg in the liver and brain decreased, while the content in the kidneys and pelt increased during the second and third week. The highest amount of 203Hg was generally found in the pelt, which indicated that unweaned hamster pups primarily excrete MeHg by binding to hair. The chemical form of mercury in the liver and kidneys of the pups was determined by ion-exchange separation of inorganic Hg and MeHg followed by γ-counting. The amount of inorganic Hg in the liver of the pups remained constant throughout the experiment, while it increased in the kidneys after one week due to the demethylation of MeHg. The inorganic Hg in the liver of newborn pups was probably due to maternal demethylation of MeHg and transplacental transfer of inorganic Hg. This hypothesis was supported by the observed transplacental transfer of inorganic Hg in pregnant dams administered 203HgCl2 on day 12 of gestation. (au) 31 refs

    2012-11-01

    To complement the recent genomic sequencing of Chinese hamster ovary (CHO) cells, proteomic analysis was performed on CHO cells including the cellular proteome, secretome, and glycoproteome using tandem mass spectrometry (MS/MS) of multiple fractions obtained from gel electrophoresis, multidimensional liquid chromatography, and solid phase extraction of glycopeptides (SPEG). From the 120 different mass spectrometry analyses generating 682,097 MS/MS spectra, 93,548 unique peptide sequences were identified with at most 0.02 false discovery rate (FDR). A total of 6164 grouped proteins were identified from both glycoproteome and proteome analysis, representing an 8-fold increase in the number of proteins currently identified in the CHO proteome. Furthermore, this is the first proteomic study done using the CHO genome exclusively, which provides for more accurate identification of proteins. From this analysis, the CHO codon frequency was determined and found to be distinct from humans, which will facilitate expression of human proteins in CHO cells. Analysis of the combined proteomic and mRNA data sets indicated the enrichment of a number of pathways including protein processing and apoptosis but depletion of proteins involved in steroid hormone and glycosphingolipid metabolism. Five-hundred four of the detected proteins included N-acetylation modifications, and 1292 different proteins were observed to be N-glycosylated. This first large-scale proteomic analysis will enhance the knowledge base about CHO capabilities for recombinant expression and provide information useful in cell engineering efforts aimed at modifying CHO cellular functions.

  20. The hamster flank organ model: Is it relevant to man

    International Nuclear Information System (INIS)

    The critical role that androgens play in the etiology of acne has led to a search for topically active antiandrogens and the frequent use of the flank organ of the golden Syrian hamster as an animal model. 17-alpha-propyltestosterone (17-PT) has been identified as having potent antiandrogenic activity in the hamster model, and this report describes its clinical evaluation. Two double-blind placebo controlled studies comparing 4% 17-PT in 80% alcohol versus vehicle alone were conducted. One study examined 17-PT sebosuppressive activity in 20 subjects. The second study examined its efficacy in 44 subjects having mild to moderate acne. A third study measured in vitro percutaneous absorption of 17-PT through hamster flank and monkey skin, and human face skin in-vivo, using radioactive drug. 17-PT was found to be ineffective in reducing either the sebum excretion rate or the number of inflammatory acne lesions. Failure of 17-PT to show clinical activity was not a result of poor percutaneous absorption. Total absorption in man was 7.7% of the dose and only 1.0% in the hamster. The sebaceous gland of hamster flank organ is apparently more sensitive to antiandrogens than the human sebaceous gland

    The Syrian golden hamster drinks alcohol readily, but only achieves moderate blood alcohol levels, and does not go through withdrawal from alcohol. Because the hamster is a model of caloric homeostasis, both caloric content and reward value may contribute to the hamster’s alcohol consumption. The current study examines alcohol consumption in the hamster when a caloric or non-caloric sweet solution is concurrently available and caloric intake in the hamster before, during, and after exposure t...

  4. Inspecting Baby Skyrmions with Effective Metrics

    CERN Document Server

    Gibbons, Gary

    2014-01-01

    In the present paper we investigate the causal structure of the baby Skyrme model using appropriate geometrical tools. We discuss several features of excitations propagating on top of background solutions and show that the evolution of high frequency waves is governed by a curved effective geometry. Examples are given for which the effective metric describes the interaction between waves and solitonic solutions such as kinks, antikinks and Hedgehogs. In particular, it is shown how violent processes involving the collisions of solitons and antisolitons may induce metrics which are not globaly hyperbolic. We argue that it might be illuminating to calculate the effective metric as a diagnostic test for pathological regimes in numerical simulations.

  8. Baby Skyrme model and fermionic zero modes

    CERN Document Server

    Queiruga, J M

    2016-01-01

    In this work we investigate some features of the fermionic sector of the supersymmetric version of the baby Skyrme model. We find that, in the background of BPS compact Skyrmions, fermionic zero modes are confined to the defect core. Further, we show that, while three SUSY generators are broken in the defect core, SUSY is completely restored outside. We study also the effect of a D-term deformation of the model. Such a deformation allows for the existence of fermionic zero modes and broken SUSY outside the compact defect.

  9. Genitourinary changes in hamsters infected and reinfected with Trypanosoma cruzi

    2003-01-01

    Full Text Available Authors describe genitourinary changes in male hamsters infected and reinfected with Trypanosoma cruzi. Changes in genital organs have been described in human and in experimental chagasic infection. Genital dysfunctions in chronic chagasic patients affect ejaculation, libido and sexual potency, and testis biopsies may show arrested maturation of germ cells, oligozoospermia and azoospermia. Sixty-five male hamsters were inoculated and reinoculated with 2x10³ trypomastigotes of T. cruzi VIC strain, and 22 non-infected animals constituted the control group. Animals were necropsied and fragments from testis, epididymis, seminal vesicle and bladder were collected and stained with hematoxylin-eosin. Peroxidase anti-peroxidase procedure was utilized to detect tissue parasitism. T. cruzi nests were found in testis, epididymis and seminal vesicle of these hamsters. Such parasitism plays a role in the origin of genital lesions observed in humans and laboratory animals during chronic chagasic infection.

    2013-01-01

    Fibrosis of the kidney glomerulus and interstitium are characteristic features of almost all chronic kidney diseases. Fibrosis is tightly associated with destruction of capillaries, inflammation, and epithelial injury which progresses to loss of nephrons, and replacement of kidney parenchyma with scar tissue. Understanding the origins and nature of the cells known as myofibroblasts that make scar tissue is central to development of new therapeutics for kidney disease. Whereas many cell lineages in the body have become defined by well-established markers, myofibroblasts have been much harder to identify with certainty. Recent insights from genetic fate mapping and the use of dynamic reporting of cells that make fibrillar collagen in mice have identified with greater clarity the major population of myofibroblasts and their precursors in the kidney. This review will explore the nature of these cells in health and disease of the kidney to underst and their central role in the pathogenesis of kidney disease. PMID:24187654

  11. Asbestos cement dust inhalation by hamsters

    Wehner, A.P.; Dagle, G.E.; Cannon, W.C.; Buschbom, R.L. (Pacific Northwest Laboratories, Richland, WA (USA))

    1978-12-01

    Two groups of 96 male Syrian golden hamsters were exposed to respirable asbestos cement aerosol at concentrations of approximately 1 and approximately 10 micrograms/liter, respectively, 3 hours/day, 5 days/week. Average fiber counts ranged from 5 to about 120 fibers/cm3. Each group was randomly divided into six subgroups of 16 animals. The first subgroup was sacrificed after 3 months of exposure, the second after 6 months, and the third after 15 months. The fourth subgroup was withdrawn from exposure after 3 months, observed for an additional 3 months, and then sacrificed. The fifth and sixth subgroups were withdrawn after 3 and 6 months of exposure, respectively, and maintained for observation up to the 15-month exposure point of the third subgroup at which time all surviving animals were sacrificed. All other experimental procedures were similar to those delineated in a previous publication describing the development of an animal model, techniques, and an exposure system for asbestos cement dust inhalation. The asbestos cement exposures had no significant effect on body weight and mortality of the animals. Higher aerosol concentration and longer exposure times increased the number of macrophages and ferruginous bodies found in the lungs of the exposed animals. Recovery periods had no effect on the incidence of macrophages and ferruginous bodies. The incidence of very slight to slight fibrosis in the animals sacrificed after 15 months of exposure shows a significant (P less than 0.01) trend when the untreated control group and the 1 and 10 microgram/liter dose level groups are compared, indicating a dose-response relationship. Development of minimal fibrosis continued in animals withdrawn from exposure. No primary carcinomas of the lung and respiratory tract and no mesotheliomas were found.

  12. Hamster thecal cells express muscle characteristics

    International Nuclear Information System (INIS)

    Contraction of the follicular wall about the time of ovulation appears to be a coordinated event; however, the cells that mediate it remain poorly studied. We examined the theca externa cells in the wall of hamster follicles for the presence of a functional actomyosin system, both in developing follicles and in culture. We used a monoclonal antibody (HHF35) that recognizes the alpha and gamma isoelectric variants of actin normally found in muscle, but not the beta variant associated with non-muscle sources, to evaluate large preovulatory follicles for actin content and composition. Antibody staining of sectioned ovaries showed intense circumferential reactivity in the outermost wall of developing follicles. Immunoblots from two-dimensional gels of theca externa lysates demonstrated the presence of the two muscle-specific isozymes of actin. Immunofluorescence of cultured follicular cells pulse-labeled with [3H] thymidine (for autoradiographic detection of DNA replication) revealed the presence, in many dividing cells, of actin filaments aligned primarily along the longitudinal axis of the cells. In cultures exposed to the calcium ionophore A23187 (10(-4) M) for varying periods (5 min to 1 h), contraction of many individual muscle-actin-positive cells was observed. Immunofluorescence of these cells, fixed immediately after ionophore-induced contraction, revealed compaction of the actin filaments. Our findings demonstrate that the cells of the theca externa contain muscle actins from an early stage and that these cells are capable of contraction even while proliferating in subconfluent cultures. They suggest that follicular growth may include a naturally occurring developmental sequence in which a contractile cell type proliferates in the differentiated state

  13. Autonomic nervous dysfunction in hamsters infected with West Nile virus.

    Directory of Open Access Journals (Sweden)

    Hong Wang

    Full Text Available Clinical studies and case reports clearly document that West Nile virus (WNV can cause respiratory and gastrointestinal (GI complications. Other functions controlled by the autonomic nervous system may also be directly affected by WNV, such as bladder and cardiac functions. To investigate how WNV can cause autonomic dysfunctions, we focused on the cardiac and GI dysfunctions of rodents infected with WNV. Infected hamsters had distension of the stomach and intestines at day 9 after viral challenge. GI motility was detected by a dye retention assay; phenol red dye was retained more in the stomachs of infected hamsters as compared to sham-infected hamsters. The amplitudes of electromygraphs (EMGs of intestinal muscles were significantly reduced. Myenteric neurons that innervate the intestines, in addition to neurons in the brain stem, were identified to be infected with WNV. These data suggest that infected neurons controlling autonomic function were the cause of GI dysfunction in WNV-infected hamsters. Using radiotelemetry to record electrocardiograms and to measure heart rate variability (HRV, a well-accepted readout for autonomic function, we determined that HRV and autonomic function were suppressed in WNV-infected hamsters. Cardiac histopathology was observed at day 9 only in the right atrium, which was coincident with WNV staining. A subset of WNV infected cells was identified among cells with hyperpolarization-activated cyclic nucleotide-gated potassium channel 4 (HCN4 as a marker for cells in the sinoatrial (SA and atrioventricular (AV nodes. The unique contribution of this study is the discovery that WNV infection of hamsters can lead to autonomic dysfunction as determined by reduced HRV and reduced EMG amplitudes of the GI tract. These data may model autonomic dysfunction of the human West Nile neurological disease.

    1979-10-01

    The CB/Ss LAK strain of inbred hamster was used as a model for studies of infection with Treponema pertenue and of acquired resistance to it. When infected, this strain developed cutaneous lesions which lasted for six to seven months, even in the presence of peak titres of antitreponemal antibody. The rate of appearance and resolution of these lesions varied with the size of the inoculum. The infected hamsters' inguinal lymph nodes increased significantly in weight and teemed with treponemes for several weeks. Animals infected for eight or 10 weeks obtained quick resolution of their lesions by treatment with penicillin and were thereafter resistant to reinfection. PMID:509189

  16. Export Marketing of Croatian Baby Beef

    Directory of Open Access Journals (Sweden)

    2003-09-01

    Full Text Available Croatia has traditionally been the exporter of livestock and beef. In 1988 Croatia exported a record of 35,7 thousand tons of livestock, worth almost 60 million US $. During the period between 1981 and 1991, the export of beef and processed meat was somewhat smaller, about 12,8 thousand tons, 40 million US $ worth. The most important export destinations were Italy, with almost 90% of all volume and monetary value of export, and Greece. In March 1993 EU has banned the import of livestock and beef from Croatia, due to a scandal with infected cattle. In spite of the subsequent abolition of this ban, Croatian export never really recovered, so today the export of beef amounts to less than a thousand tons. Even though the conditions on the export markets and in the domestic cattle breeding industry have changed, we think that it is possible to achieve the export expansion of Croatian baby beef in the foreign market. This article describes the results of the research conducted on the Italian and Greek market. According to expert opinions and the results of our survey it is evident that, with a certain quality of the product, it would be possible to renew the export of Croatian baby beef to the target markets.

    1995-07-01

    The campaign for exclusive breast-feeding in a baby-friendly hospital at Prapokklao Hospital, Chanthaburi was increased. The contributory factors was likely due to enforcement of early bonding and attachment, by rooming-in of infants in the materity ward. After cessation of comprehensive intervention exclusive breast-feeding dropped significantly but increased in predominant breast-feeding. This might be due to family influence with the suggestion to give water in addition to breast milk. Data shows that rooming-in is essential in the promotion of breast-feeding. A decreased of abandoned children indicates early bonding. To sustain a baby-friendly hospital, 10 steps to successful breast-feeding must be followed strictly. Intervention activities must be done continuously with cooperation of health providers at all levels. It is felt that breast-feeding should not be considered a maternal instinct but a new behavior that needs to be changed to a point that mothers adopt breast-feeding practices for 4 months after delivery.

  18. Massage Changes Babies' Body, Brain and Behavior

    Science.gov (United States)

    Ishikawa, Chihiro; Shiga, Takashi

    Tactile stimulation is an important factor in mother-infant interactions. Many studies on both human and animals have shown that tactile stimulation during the neonatal period has various beneficial effects in the subsequent growth of the body and brain. In particular, massage is often applied to preterm human babies as “touch care”, because tactile stimulation together with kinesthetic stimulation increases body weight, which is accompanied by behavioral development and the changes of endocrine and neural conditions. Among them, the elevation of insulin-like growth factor-1, catecholamine, and vagus nerve activity may underlie the body weight gain. Apart from the body weight gain, tactile stimulation has various effects on the nervous system and endocrine system. For example, it has been reported that tactile stimulation on human and animal babies activates parasympathetic nervous systems, while suppresses the hypothalamic-pituitary-adrenalcortical (HPA) axis, which may be related to the reduction of emotionality, anxiety-like behavior, and pain sensitivity. In addition, animal experiments have shown that tactile stimulation improves learning and memory. Facilitation of the neuronal activity and the morphological changes including the hippocampal synapse may underlie the improvement of the learning and memory. In conclusion, it has been strongly suggested that tactile stimulation in early life has beneficial effects on body, brain structure and function, which are maintained throughout life.

  19. Japan's baby bust: an economic issue?

    Science.gov (United States)

    1998-09-01

    This brief article articulates that the solution to the declining birthrate in Japan is to change the corporate culture and societal values and begin putting the family first. At the present rate of fertility decline, Japan could well have just over 67 million total population in another 100 years, which is 50% of the present total. In 1990, the Finance Minister tried to convince Japanese couples to have more babies by abandoning policies that led women to higher education. The implication is that women would then want to stay at home and have babies. The prosperity of the late 1980s and early 1990s did not encourage higher fertility. The likely reason for low fertility is the male-dominated, corporate culture where male workers leave home early in the morning and work till late at night. Wives are left to care for children and maintain a full-time job. The total fertility rate (TFR) was 3.65 in 1950 and 1.39 in 1998. Both Germany and Italy have lower fertility but higher rates of immigration. The decline in the TFR is responsible for many of the current economic policies. New taxes were introduced in 1997 to pay for social security of the aged, and then the economy stalled. Life expectancies continue to rise. The elderly are a larger proportion of total population than children aged under 15 years. Women marry late, and the divorce rate is high. PMID:12348885

    2011-12-01

    Healthcare providers recognize the important role played by attachment theory in explaining the close relationship between mental health and social behavior in mothers and their children. This paper uses attachment theory in a socio-cultural context to ascertain the mechanism by which baby slings/carriers, a new technology, produced and reproduced the scientific motherhood. It further applies a social history of technology perspective to understand how baby carriers and attachment theory are socially constructed and historically contingent on three major transformations. These transformations include the use of attachment theory-based baby carriers to further scientific motherhood; the use of baby slings/carriers to further the medicalization of breastfeeding and enhance mother-infant attachment; and the use of baby slings/carriers to transform woman's identities by integrating scientific motherhood, independence and fashion. Implications for nursing clinical policy are suggested. PMID:22113629

In the present study we describe the course of T. pisiformis infection in experimentally infected golden hamsters. Ten females, treated with methyl-prednisolone acetate were infected with three T. pisiformis cysticerci each one excised from one rabbit. Proglottids released in faeces and adults recovered during necropsy showed that all animals were infected. Eggs obtained from the hamsters' tapeworms, were assessed for viability using trypan blue or propidium iodide stains. Afterwards, some rabbits were inoculated with eggs, necropsy was performed after seven weeks and viable cysticerci were obtained. Our results demonstrate that the experimental model of adult Taenia pisiformis in golden hamster can replace the use of canines in order to study this parasite and to provide eggs and adult tapeworms to be used in different types of experiments.

    Abstract Background There is evidence that exposure to passive smoking in general, and in babies in particular, is an important cause of morbimortality. Passive smoking is related to an increased risk of pediatric diseases such as sudden death syndrome, acute respiratory diseases, worsening of asthma, acute-chronic middle ear disease and slowing of lung growth. The objective of this article is to describe the BIBE study protocol. The BIBE study aims to determine the effectiveness of a brief i...

  12. Baby Skyrmions in AdS

    2015-01-01

    We study the baby Skyrme model in a pure AdS background without a mass term. The tail decays and scalings of massless radial solutions are demonstrated to take a similar form to those of the massive flat space model, with the AdS curvature playing a similar role to the flat space pion mass. We also numerically find minimal energy solutions for a range of higher topological charges and find that they form concentric ring-like solutions. Popcorn transitions (named in analogy with studies of toy models of holographic QCD) from an n layer to an n+1-layer configuration are observed at topological charges 9 and 27 and further popcorn transitions for higher charges are predicted. Finally, a point-particle approximation for the model is derived and used to successfully predict the ring structures and popcorn transitions for higher charge solitons.

  13. Failure to thrive in babies and toddlers.

    Goh, Lay Hoon; How, Choon How; Ng, Kar Hui

    2016-06-01

    Failure to thrive in a child is defined as 'lack of expected normal physical growth' or 'failure to gain weight'. Diagnosis requires repeated growth measurements over time using local, age-appropriate growth centile charts. Premature babies with appropriate growth velocity and children with 'catch-down' growth, constitutional growth delay or familial short stature show normal growth variants, and usually do not require further evaluation. In Singapore, the most common cause of failure to thrive in children is malnutrition secondary to psychosocial and caregiver factors. 'Picky eating' is common in the local setting and best managed with an authoritative feeding style from caregivers. Other causes are malabsorption and existing congenital or chronic medical conditions. Child neglect or abuse should always be ruled out. Iron deficiency is the most common complication. The family doctor plays a pivotal role in early detection, timely treatment, appropriate referrals and close monitoring of 'catch-up' growth in these children. PMID:27353148

  14. Boltzmann babies in the proper time measure

    2007-12-20

    After commenting briefly on the role of the typicality assumption in science, we advocate a phenomenological approach to the cosmological measure problem. Like any other theory, a measure should be simple, general, well defined, and consistent with observation. This allows us to proceed by elimination. As an example, we consider the proper time cutoff on a geodesic congruence. It predicts that typical observers are quantum fluctuations in the early universe, or Boltzmann babies. We sharpen this well-known youngness problem by taking into account the expansion and open spatial geometry of pocket universes. Moreover, we relate the youngness problem directly to the probability distribution for observables, such as the temperature of the cosmic background radiation. We consider a number of modifications of the proper time measure, but find none that would make it compatible with observation.

    2012-01-01

    The increasing awareness of climate change has led or- ganizations to demand a standard procedure to measure and com- municate greenhouse gas (GHG) emissions linked to their products or services. The publicly available specification PAS 2050 has been developed in response to broad community and industry desire for a consistent method-carbon footprint for assessing the life cycle GHG emissions of goods and services. Specifically, this paper illustrates the implementation of carbon footprint for a baby stroller in accordance with PAS 2050. A fial value of 321 kg per one stroller including package was calculated. Moreover, the study led to identify raw materials production of the stroller as the main source of GHS emissions where efforts need to focus for emission reduction opportunities. This case study is hoped to be a starting point for organizations to benefit from the increasing application of carbon footprint assessment.

  16. Primary health care of the newborn baby.

    1990-01-01

    More than 50% of infant deaths in India occur during the neonatal period. High priority therefore needs to be given to improving the survival of newborns. A large number of neonatal deaths have their origin in the perinatal period and are mainly determined by the health and nutritional status of the mother, the quality of care during pregnancy and delivery, and the immediate care of the newborn at birth. Main causes of neonatal mortality are birth asphyxia, respiratory problems, and infections, especially tetanus. Most such deaths occur among low birthweight babies. Hypothermia, undernutrition, and mismanaged breast feeding may also indirectly contribute to neonatal mortality. Community-based studies have, however, demonstrated that most neonatal mortality can be affordably prevented through primary health care. Efforts are underway to expand the health care infrastructure, but the outreach of maternal and child health care remains unsatisfactory especially in rural areas. PMID:12319228

  17. Seasonal aspects of sleep in the Djungarian hamster

    2003-05-01

    Full Text Available Abstract Background Changes in photoperiod and ambient temperature trigger seasonal adaptations in the physiology and behaviour of many species, including the Djungarian hamster. Exposure of the hamsters to a short photoperiod and low ambient temperature leads to a reduction of the polyphasic distribution of sleep and waking over the light and dark period. In contrast, a long photoperiod enhances the daily sleep-wake amplitude leading to a decline of slow-wave activity in NREM sleep within the light period. It is unknown whether these changes can be attributed specifically to photoperiod and/or ambient temperature, or whether endogenous components are contributing factors. The influence of endogenous factors was investigated by recording sleep in Djungarian hamsters invariably maintained at a low ambient temperature and fully adapted to a short photoperiod. The second recording was performed when they had returned to summer physiology, despite the maintenance of the 'winter' conditions. Results Clear winter-summer differences were seen in sleep distribution, while total sleep time was unchanged. A significantly higher light-dark cycle modulation in NREM sleep, REM sleep and waking was observed in hamsters in the summer physiological state compared to those in the winter state. Moreover, only in summer, REM sleep episodes were longer and waking bouts were shorter during the light period compared to the dark period. EEG power in the slow-wave range (0.75–4.0 Hz in both NREM sleep and REM sleep was higher in animals in the summer physiological state than in those in the 'winter' state. In winter SWA in NREM sleep was evenly distributed over the 24 h, while in summer it decreased during the light period and increased during the dark period. Conclusion Endogenous changes in the organism underlie the differences in sleep-wake redistribution we have observed previously in hamsters recorded in a short and long photoperiod.

    The objective of this study was to examine the effects of polyethylene glycol (PEG) treated red blood cells (RBCs) on the microcirculation in a hamster back skin window chamber model. Donor hamster RBCs were PEGylated through an incubation with an activated PEG solution, washed, resuspended, and infused through a 10% volume top loading procedure into the carotid artery in an awake Syrian Golden hamster. Eight hamster groups were treated with activated PEG different sizes and concentrations: 0.05 mM-5 kDa PEG, 0.5 mM-5 kDa PEG, 1.1 mM-5 kDa PEG, 2.2 mM-5 kDa PEG, 22 mM-5 kDa PEG, 0.05 mM-20 kDa PEG, 0.5 mM-20 kDa PEG, and 5 mM-20 kDa PEG. Non-treated RBCs were used as control. The microvascular bed under observation was videotaped 30 min before the infusion and followed for 30 min post infusion. The diameter of individual blood vessels and blood flow velocities in selected vessels was measured. Hematocrit and hemoglobin concentration were recorded before infusion and at the end of experiment. Tissue pO(2) was also monitored. Results showed the hamsters tolerated the PEGylated RBCs without apparent ill effects. No significant changes were recorded for the hematocrit, the hemoglobin concentration, the blood vessel diameters, blood flow velocities, and the interstitial partial oxygen pressure (pO(2)) before, during, and after the injections of PEG-RBCs (P > 0.05). Unlike most hemoglobin-based oxygen carrying compounds, which can cause vasoconstriction, the PEGylated RBCs did not produce any measurable vasoactivity. Together with the absence of rouleaux formation and the fact that PEG molecules can mask the surface antigens on RBCs, PEGylation appeared promising as a circulation enhancement treatment.

    Kidney transplantation is the best approach for treating patients with end stage renal disease, offering patients the best chance of returning to normal health. While the techniques used in kidney transplantation surgery are mature and highly successful, there is a severe shortage of donor organs. Statistics show a serious imbalance between organ donations and patients on the waiting list for organ transplantation. Moreover, evidence from empirical studies has shown a better transplantation outcome for patients who receive living donor transplantation than for those who receive organs from cadavers. Although using relatives as donors offers an effective way to reduce the problem of organ shortage, this strategy faces many challenges and many other factors affect the promotion of living donor transplantation. This article elaborates how cultural and psychological factors, kidney transplantation awareness, and ethics and laws impact upon living kidney donations and then proposes coping strategies for promoting living kidney transplantation.

    2015-09-01

    Improved life sustaining technology in the neonatal intensive care unit (NICU) has resulted in an increased probability of survival in extremely premature babies. Miracle baby stories in the popular press are a regular occurrence and these reports are often the first source from which the general public learn about extremely premature babies. The research from which this paper is drawn sought to explore the care-giving and ethical dilemmas of neonatal nurses when caring for extremely premature babies 24 weeks gestation and less. This current paper aims to outline the views of neonatal nurses on miracle baby stories in the media. Data were collected via a questionnaire to 760 Australian neonatal nurses with 414 returned, representing a response rate of 54.4%. Narrative was collected from semi-structured interviews with 24 experienced neonatal nurses in NSW, Australia. A qualitative approach utilising thematic analysis was utilised to analyse the data. The theme the myth of the miracle baby is seen as generating myths and unrealistic expectations on the part of vulnerable families and the public. Neonatal nurses, as the primary caregivers for tiny babies and their families, viewed popular media publications with suspicion, believing published reports to be incomplete, inaccurate and biased towards the positive.

  10. A LigA three-domain region protects hamsters from lethal infection by Leptospira interrogans.

    Directory of Open Access Journals (Sweden)

    Mariana L Coutinho

    2011-12-01

    Full Text Available The leptospiral LigA protein consists of 13 bacterial immunoglobulin-like (Big domains and is the only purified recombinant subunit vaccine that has been demonstrated to protect against lethal challenge by a clinical isolate of Leptospira interrogans in the hamster model of leptospirosis. We determined the minimum number and location of LigA domains required for immunoprotection. Immunization with domains 11 and 12 was found to be required but insufficient for protection. Inclusion of a third domain, either 10 or 13, was required for 100% survival after intraperitoneal challenge with Leptospira interrogans serovar Copenhageni strain Fiocruz L1-130. As in previous studies, survivors had renal colonization; here, we quantitated the leptospiral burden by qPCR to be 1.2×10(3 to 8×10(5 copies of leptospiral DNA per microgram of kidney DNA. Although renal histopathology in survivors revealed tubulointerstitial changes indicating an inflammatory response to the infection, blood chemistry analysis indicated that renal function was normal. These studies define the Big domains of LigA that account for its vaccine efficacy and highlight the need for additional strategies to achieve sterilizing immunity to protect the mammalian host from leptospiral infection and its consequences.

    Full Text Available Three leptospiral bacterins, produced with different serovars of Serogroup Sejroe, namely the hardjo (bacterin A, wolffi (bacterin B and guaricura (bacterin C, were evaluated in male hamsters (Mesocricetus auratus by comparing the agglutinating and neutralizing antibodies titers using microscopic agglutination (MAT and in vitro growth inhibition (GIT tests. The immunization schedule was based on two 1.0 mL doses of non-diluted formalininactivated whole culture bacterin given through subcutaneous route with 10-day interval. The challenge was performed ten days after the second vaccine dose, when the animals were inoculated with 0.2 mL of non-inactivated cultures of each serovar through intraperitoneal route. On the 21st post-challenge day (PCD, all animals were bled and their sera were joined in pools (n=8 and tested by MAT and GIT. All vaccinated and control animals presented no clinical signs of leptospirosis after the challenge, but the serovar guaricura was isolated from the kidneys of control animals on the 21st PCD. The MAT results showed cross agglutinins between serovars hardjo and wolffi, and between wolffi and guaricura. The GIT results revealed the presence of cross neutralizing antibodies between serovars wolffi or guaricura against hardjo, wolffi and guaricura. It was found that the tested strain of serovar hardjo did not produce detectable levels of neutralizing antibodies, indicating its poor immunogenicity.

  17. Heat and cold acclimation in helium-cold hypothermia in the hamster.

    Science.gov (United States)

    Musacchia, X. J.

    1972-01-01

    A study was made of the effects of acclimation of hamsters to high (34-35 C) and low (4-5 C) temperatures for periods up to 6 weeks on the induction of hypothermia in hamsters. Hypothermia was achieved by exposing hamsters to a helox mixture of 80% helium and 20% oxygen at 0 C. Hypothermic induction was most rapid (2-3 hr) in heat-acclimated hamsters and slowest (6-12 hr) in cold-acclimated hamsters. The induction period was intermediate (5-8 hr) in room temperature nonacclimated animals (controls). Survival time in hypothermia was relatable to previous temperature acclimations. The hypothesis that thermogenesis in cold-acclimated hamsters would accentuate resistance to induction of hypothermia was substantiated.

  18. TELOMERASE ACTIVITY DURING 7, 12-DIMETHYLBENZ [a] ANTHRACENE-INDUCED HAMSTER BUCCAL POUCH CARCINOGENESIS

    Institute of Scientific and Technical Information of China (English)

    2000-01-01

    Objective: To investigate the roles of telomerase activity (TA) in relation to hamster buccal pouch tumor progression. Methods: male hamster were treated three times weekly with 0.5% of 7, 12-dimethyl- benzanthracene (DMBA) over a 15 weeks experimental period. Hamsters were sacrificed at 3, 6, 9, 12 and 15 weeks after treatment. Telomerase activity of hamster buccal pouch tissue were measured along with the analyses of the formation of DMBA-induced hamster buccal pouch tumors. Results: DMBA-induced squamous cell carcinomas were found at the 6th week after dosing. Telomerase activity elevation began at the 3rd week and was increasing to a plateau at the 12th week. Conclusion: Our results show that telomerase activity in the target tissue may be detected at the early stage of the DMBA-induced hamster buccal pouch tumor formation and suggests that telomerase activity may be used as a biomarker for an early clinical detection of buccal pouch cancer.

  19. Alpha 2-adrenergic receptor turnover in adipose tissue and kidney: irreversible blockade of alpha 2-adrenergic receptors by benextramine

    Energy Technology Data Exchange (ETDEWEB)

    Taouis, M.; Berlan, M.; Lafontan, M.

    1987-01-01

    The recovery of post- and extrasynaptic alpha 2-adrenergic receptor-binding sites was studied in vivo in male golden hamsters after treatment with an irreversible alpha-adrenoceptor antagonist benextramine, a tetramine disulfide that possesses a high affinity for alpha 2-binding sites. The kidney alpha 2-adrenergic receptor number was measured with (/sup 3/H)yohimbine, whereas (/sup 3/H)clonidine was used for fat cell and brain membrane alpha 2-binding site identification. Benextramine treatment of fat cell, kidney, and brain membranes reduced or completely suppressed, in an irreversible manner, (/sup 3/H) clonidine and (/sup 3/H)yohimbine binding without modifying adenosine (A1-receptor) and beta-adrenergic receptor sites. This irreversible binding was also found 1 and 2 hr after intraperitoneal administration of benextramine to the hamsters. Although it bound irreversibly to peripheral and central alpha 2-adrenergic receptors on isolated membranes, benextramine was unable to cross the blood-brain barrier of the hamster at the concentrations used (10-20 mg/kg). After the irreversible blockade, alpha 2-binding sites reappeared in kidney and adipose tissue following a monoexponential time course. Recovery of binding sites was more rapid in kidney than in adipose tissue; the half-lives of the receptor were 31 and 46 hr, respectively in the tissues. The rates of receptor production were 1.5 and 1.8 fmol/mg of protein/hr in kidney and adipose tissue. Reappearance of alpha 2-binding sites was associated with a rapid recovery of function (antilipolytic potencies of alpha 2-agonists) in fat cells inasmuch as occupancy of 15% of (/sup 3/H)clonidine-binding sites was sufficient to promote 40% inhibition of lipolysis. Benextramine is a useful tool to estimate turnover of alpha 2-adrenergic receptors under normal and pathological situations.

    While situation theory and situation semantics provide an appropriate framework for a realistic model-theoretic treatment of natural language, serious thinking on their `computational' aspects has just started. Existing proposals mainly offer a Prolog- or Lisp-like programming environment with varying degrees of divergence from the ontology of situation theory. In this paper, we introduce a computational medium (called BABY-SIT) based on situations. The primary motivation underlying BABY-SIT ...

    We study the baby Skyrme model as a theory that interpolates between two distinct BPS systems. For this a near-BPS approximation can be used which, however, involves a small deviation from each of the two BPS limits. We provide analytical explanation and numerical support for the validity of this approximation. We then study the set of all possible supersymmetric extensions of the baby Skyrme model with ${\\cal N}=1$ and the particular ones with extended ${\\cal N}=2$ supersymmetries and relate...

  8. Cystolithiasis in a Syrian hamster: a different outcome

    Directory of Open Access Journals (Sweden)

    D. Petrini

    2016-08-01

    Full Text Available A 14-month-old intact male Syrian hamster was admitted for lethargy and hematuria. A total body radiographic image and abdominal ultrasonography showed the presence of a vesical calculus. During cystotomy, a sterile urine sample was obtained and sent to the diagnostic laboratory along with the urolith for analysis. Urine culture was found negative for bacterial growth, and the urolith was identified as a calcium-oxalate stone. Diet supplementation with palmitoylethanolamide, glucosamine and hesperidin was adopted the day after discharge. One year follow up revealed no presence of vesical calculi. Although this is the report of a single clinical case, this outcome differs from the results reported in the literature characterized by recurrences after few months. Considering the positive outcome and the beneficial properties of palmitoylethanolamide, glucosamine, and hesperidin, these nutritional elements in Syrian hamsters, are recommended to reduce recurrence after surgical treatment of urolithiasis.

  9. Inorganic arsenic levels in baby rice are of concern

    International Nuclear Information System (INIS)

    Inorganic arsenic is a chronic exposure carcinogen. Analysis of UK baby rice revealed a median inorganic arsenic content (n = 17) of 0.11 mg/kg. By plotting inorganic arsenic against total arsenic, it was found that inorganic concentrations increased linearly up to 0.25 mg/kg total arsenic, then plateaued at 0.16 mg/kg at higher total arsenic concentrations. Inorganic arsenic intake by babies (4-12 months) was considered with respect to current dietary ingestion regulations. It was found that 35% of the baby rice samples analysed would be illegal for sale in China which has regulatory limit of 0.15 mg/kg inorganic arsenic. EU and US food regulations on arsenic are non-existent. When baby inorganic arsenic intake from rice was considered, median consumption (expressed as μg/kg/d) was higher than drinking water maximum exposures predicted for adults in these regions when water intake was expressed on a bodyweight basis. - Median consumption of organic arsenic levels for UK babies from baby rice is above threshold considered safe

    Full Text Available To evaluate iodine intake in Japanese infants, iodine contents were determined in both commercial and homemade baby food samples consumed in Japan. Fifty-three samples of commercial bottled or retort baby food and 25 samples of homemade baby food for one day were collected and their iodine contents were determined by inductively coupled plasma mass spectrometry after an extraction with 0.5% tetramethylammonium hydroxide. Among the commercial baby food samples, 35 samples showed low iodine values ( 1000 ng/g wet weight. Significantly higher iodine values were observed in 15 samples composed of dishes cooked using kombu (a kind of kelp than other samples. Among the homemade baby food samples, 12 samples brought very low iodine intake (< 1- 24 μg/d, while 5 samples brought very high iodine intake (283-978 μg/d. These results indicate that intermittent high iodine baby food including dishes cooked using kombu contributes to sufficient iodine intake in Japanese infants.

    Seasonal changes in the length of the daily photoperiod induce significant changes in social behavior. Hamsters housed in winter-like short photoperiods (SP) can express significantly higher levels of aggression than hamsters housed in long photoperiods (LP) that mimic summer. The mechanisms responsible for increasing aggressiveness in SP-exposed female hamsters are not well understood but may involve seasonal changes in the endocrine system. In experiment 1, the effects of SP exposure on the...

    Bioenergetic studies on hamsters during depressed metabolic states are reported. External support of blood glucose extended the survival times of hibernating animals. Radioresistance increased in hibernating as well as in hypothermic hamsters. Marked changes in hamster catecholamine turnover rates were observed during acclimatization to high temperature stress. High radioresistance levels of the gerbil gastrointestinal system were attributed in part to the ability of the gut to maintain functional integrity.

    NASA's Phoenix Mars Lander's Surface Stereo Imager took this image on Sol 14 (June 8, 2008), the 14th Martian day after landing. It shows two trenches dug by Phoenix's Robotic Arm. Soil from the right trench, informally called 'Baby Bear,' was delivered to Phoenix's Thermal and Evolved-Gas Analyzer, or TEGA, on Sol 12 (June 6). The following several sols included repeated attempts to shake the screen over TEGA's oven number 4 to get fine soil particles through the screen and into the oven for analysis. The trench on the left is informally called 'Dodo' and was dug as a test. Each of the trenches is about 9 centimeters (3 inches) wide. This view is presented in approximately true color by combining separate exposures taken through different filters of the Surface Stereo Imager. The Phoenix Mission is led by the University of Arizona, Tucson, on behalf of NASA. Project management of the mission is by NASA's Jet Propulsion Laboratory, Pasadena, Calif.

    The quantitative description of cultural evolution is a challenging task. The most difficult part of the problem is probably to find the appropriate measurable quantities that can make more quantitative such evasive concepts as, for example, dynamics of cultural movements, behavior patterns and traditions of the people. A strategy to tackle this issue is to observe particular features of human activities, i.e. cultural traits, such as names given to newborns. We study the names of babies born in the United States of America from 1910 to 2012. Our analysis shows that groups of different correlated states naturally emerge in different epochs, and we are able to follow and decrypt their evolution. While these groups of states are stable across many decades, a sudden reorganization occurs in the last part of the twentieth century. We think that this kind of quantitative analysis can be possibly extended to other cultural traits: although databases covering more than one century (as the one we used) are rare, the ...

  2. Goitre and wasting induced in hamsters by hexachlorobenzene

    International Nuclear Information System (INIS)

    Male Syrian hamsters were treated with hexachlorobenzene (HCB) in their diet at levels of 100 ppm for 28 weeks, 200 ppm for 18 and 28 weeks, and 500 ppm for 6 weeks. All treatments caused at least a 2.5- to 3-fold increase in thyroid size, mainly by enlargement of some follicles. Serum thyroxine (T4) levels were unchanged, whereas levels of triiodothyronine (T3) eventually became depressed by >60%. Uptake of 131I into thyroids was induced approximately 3-fold when estimated after feeding HCB (500 ppm) for 3 or 6 weeks. Hamsters also lost weight by depletion of adipose tissue, leading to 50% mortality in longer experiments. Results were distinct from the effects of the known antithyroid agent 3-aminotriazole or amitrole (200 ppm for 28 weeks), which did not affect survival and although causing thyroid enlargement depressed serum T4 and significantly elevated T3. The effects of HCB in hamsters were also different from those in rats (500 ppm HCB for 6 weeks) in which there was only a small increase in thyroid size (1.3-fold), serum levels of T3 were only slightly depressed but T4 levels were reduced by 74%. These studies are discussed with reference to the effects of other polyhalogenated aromatic chemicals on the thyroid, serum thyroid hormone levels and lethality. (orig.)

  3. Effects of hyperthermia on the hamster immune system

    International Nuclear Information System (INIS)

    In previous studies, the authors have shown that hyperthermia can enhance antibody-complement chytotoxicity of hamster and human tumor cells. Moreover, whole body microwave exposure of hamsters resulted in activation of peritoneal macrophages to a viricidal state and transient suppression of natural killer (NK) cell activity. In this study, the authors compare the effects of whole body heating by microwaves or by an environmental chamber (hot air) on the hamster immune system. Microwave exposure (25mW/cm/sup 2/; 1 hr) caused viricidal activation of peritoneal macrophages which resulted in restriction of vaccinia and vesicular stomatitis virs (VSV) growth. However, heating in an environmental chamber (410C; 1 hr) did not activate macrophages to a viricidal state. Both microwave and hot air hyperthermia caused significant augmentation of antibody producing spleen cell response to sheep red blood cells (SRBC), using the Jerne hymolytic plaque assay, four days post exposure and immunization with SRBC. Natural killer spleen cell cytotoxicity was suppressed by microwave and hot air hyperthermia showing that NK lymphocytes are extremely sensitive to changes in temperature. These alterations in cellular immune response due to hyperthermia could be of significance in treatment of tumors and viral infections

    Nickel carbonyl was administered to groups of pregnant hamsters by inhalation on days 4, 5, 6, 7, or 8 of gestation. The dams were killed on day 15 of gestation, and the fetuses were examined for malformations. Exposure to Ni(CO)/sub 4/ on days 4 or 5 of gestation resulted in malformation in 5.5% and 5.8% of the progeny, respectively. Progeny included 9 fetuses with cystic lungs, 7 fetuses with exencephaly, 1 fetus with exencephaly plus fused rib and 1 fetus with anophthalmia plus cleft palate. Hemorrhages into serious cavities were found. In progeny of dams exposed to Ni(CO)/sub 4/ on days 6 or 7 of gestation, there was 1 fetus with fused ribs and there were 2 fetuses with hydronephrosis. In another experiment, pregnant hamsters were exposed to inhalation of Ni(CO)/sub 4/ on day 5 of gestation; these dams were permitted to deliver their litters and to nurse their pups. There was no significant difference in the average number of live pups in the Ni(CO)/sub 4/-exposed litters compared to control litters. Neonatal mortality was increased in Ni(CO)/sub 4/-exposed litters. This study demonstrates that Ni(CO)/sub 4/ is teratogenic and embryotoxic in Syrian hamsters.

  6. DNA (deoxyribonucleic acid) synthesis following microinjection of heterologous sperm and somatic cell nuclei into hamster oocytes

    International Nuclear Information System (INIS)

    The authors investigated the ability of the hamster oocyte to initiate DNA synthesis in nuclei differing in basic protein content. DNA synthesis was studied by autoradiography in oocytes that had been incubated in 3H-thymidine after being parthenogenetically activated by sham microinjection, or microinjected with hamster, mouse, rabbit, or fish sperm nuclei, or hamster hepatocyte nuclei. Within 6 hr of sham or nucleus microinjection, nuclei of each type underwent transformation into pronuclei and synthesized DNA. These results demonstrated that the hamster egg can access and utilize its own and each type of template provided, whether homologous or heterologous. However, pronuclei derived from hamster sperm nuclei were more likely to be synthesizing DNA at 6 hr than pronuclei derived from sperm nuclei of other species. The authors conclude that the mechanisms employed by the hamster oocyte to transform hamster sperm nuclei into pronuclei and to effect DNA synthesis in these nuclei are not specific for the hamster sperm nucleus. Nevertheless, these mechanisms apparently operate more efficiently when the hamster sperm nucleus, rather than a heterologous sperm nucleus, is present

    The blueback salmon fingerlings (Oncorhynchus nerka) at the U.S. Fish-Cultural Station at Winthrop, Washington, underwent an infection that was caused by a very short, Gram-positive, nonmotile, rod-shaped bacterium. A further description is impossible at this time, as the organism has not been grown satisfactorily for proper identification. The disease was characterized by white, raised areas of dead tissue mainly in the kidney: for this reason it is referred to as kidney disease. Belding and Merrill (1935) described a disease among the brook, brown, and rainbow trout at a State hatchery in Massachusetts which, from the description, might be the same as kidney disease. J.H. Wales of the California Division of Fish and Game described (unpublished manuscript, 1941) a disease in hatchery trout in California which seems to be identical to kidney disease.

  3. Should we maintain baby hatches in our society?

    Full Text Available Abstract Background A baby hatch called the “Stork’s Cradle” has been in place at Jikei Hospital in Kumamoto City, Japan, since May 10, 2007. Babyklappes were first established in Germany in 2000, and there are currently more than 90 locations. Attitudes regarding baby hatches are divided in Japan and neither opinions for nor against baby hatches have thus far been overwhelming. To consider the appropriateness of baby hatches, we present and examine the validity of each major objection to establishing baby hatches. Discussion There are various objections to baby hatches as follows: It violates a child’s right to know the identity of his or her biological parents by allowing anonymous birth; it neglects fulfillment of the biological parents’ basic obligation to raise their child and its very availability induces abandonment of infants; some people abuse it for very selfish reasons; it cannot save babies’ lives; the rights of one parent can be ignored if the other surrenders a child without his or her consent; it puts a baby in medical jeopardy; and it has no clear legal basis. The authors would argue that there are many plausible refutations for each objection mainly based on priority of child’s right to life, pregnant women’s vulnerability and necessity of anonymity, social responsibility to protect and raise children, differences between dropping a child off at a baby hatch and child neglect, limited function of social childcare center, inevitability of abuse by a minority of people, necessary distinction between outcomes that occur only because baby hatches exist and those that occur regardless of their existence, important local direct and upmost measures for women in trouble, and difference between ambiguous legality and illegality. Summary We argue that a certain number of baby hatches should continue to be established as a last resort, in a form that can maintain anonymity if the parent dropping the child off so desires. It

    Full Text Available Introduction Numerous studies on the early contact between mother and the baby and the time they spend together-common stay stress the fact that these are invaluable for the mothers, infants, family and society in general. The objective of the research. The objective of the research was to establish whether mother benefits from the early contact with her baby and the importance of the time period they spend and share together. Materials and methods The study group consisted of 216 mothers that spend the time with their babies and had the early contact with the babies as well, and the control group consisted of 216 mothers that were detached from their babies. Puerpera were observed in the aspects of the uterus involution, post delivery hemogramme on the third day after the childbirth, sanitary napkin consumption and the hospitalization length. Results For the study group the following was significant: less of the bad uterus involution, less of the post delivery anemia measured in the hemoglobin values and in the number of erythrocytes, less of the sanitary napkin consumption and the shorter hospitalization length. Discussion The early contact and the time spent with their babies after the childbirth influence the less blood loss analyzed by post delivery hemogramme, better uterus involution, less of the sanitary napkin consumption analyzed in the first three days after the childbirth and the shorter hospitalization length. The positive component of the breastfeeding oxytocic reflex is probably responsible for these effects. Conclusion Puerpera benefit from the early contact and the time spent with their babies.

    We report observations of η Carinae obtained with ALMA in the continuum of 100, 230, 280, and 660 GHz in 2012 November, with a resolution that varied from 2.''88 to 0.''45 for the lower and higher frequencies, respectively. The source is not resolved, even at the highest frequency; its spectrum is characteristic of thermal bremsstrahlung of a compact source, but different from the spectrum of optically thin wind. The recombination lines H42α, He42α, H40α, He40α, H50β, H28α, He28α, H21α, and He21α were also detected, and their intensities reveal non-local thermodynamic equilibrium effects. We found that the line profiles could only be fit by an expanding shell of dense and ionized gas, which produces a slow shock in the surroundings of η Carinae. Combined with fittings to the continuum, we were able to constrain the shell size, radius, density, temperature, and velocity. The detection of the He recombination lines is compatible with the high-temperature gas and requires a high-energy ionizing photon flux, which must be provided by the companion star. The mass-loss rate and wind velocity, necessary to explain the formation of the shell, are compatible with an luminous blue variable eruption. The position, velocity, and physical parameters of the shell coincide with those of the Weigelt blobs. The dynamics found for the expanding shell correspond to matter ejected by η Carinae in 1941 in an event similar to that which formed the Little Homunculus; for that reason, we called the new ejecta the 'Baby Homunculus'.

    Full Text Available Visceral leishmaniasis (VL is a severe chronic disease caused by Leishmania (Leishmania infantum chagasi. Better knowledge on the effects caused by this disease can help develop adequate clinical management and treatment. Parasitological and immunohistochemical studies were performed golden hamsters Mesocricetus auratus infected with bone marrow from individuals with VL in the State of Mato Grosso do Sul, central-west Brazil. The effects of parasitism in the spleen, liver, kidneys, lungs, heart and brain of the animals were examined. Eighteen hamsters were inoculated intraperitoneally, and six healthy animals were used as negative controls. The animals were kept in the animal house and checked for clinical signs. Specimens of each organ were examined for the presence of amastigotes. Immunohistochemical technique was performed in all brain specimens and organs negative on the direct examination of parasites. Direct examination of amastigotes was positive in the spleen and liver of all infected animals; 33.3% showed the parasite in the kidneys and lungs, and 16.7% in the heart. Parasitic forms were seen in 83.3% (15/18 of the brain examined. Immunohistochemistry confirmed the results of the direct examination, except in two specimens of lung tissue and in the brain specimens. Other studies are needed to further clarify the effect of the parasite in the central nervous system.A leishmaniose visceral (LV é uma doença crônica grave, causada pelo parasito Leishmania (Leishmania infantum chagasi.

    Full Text Available Aberrant autonomic signaling is being increasingly recognized as an important symptom in neuromuscular disorders. The delta-sarcoglycan-deficient BIO TO-2 hamster is recognized as a good model for studying mechanistic pathways and sequelae in muscular dystrophy and heart failure, including autonomic nervous system dysfunction. Recent studies using the TO-2 hamster model have provided promising preclinical results demonstrating the efficacy of gene therapy to treat skeletal muscle weakness and heart failure. Methods to accelerate preclinical testing of gene therapy and new drugs for neuromuscular diseases are urgently needed. The purpose of this investigation was to demonstrate a rapid non-invasive screen for characterizing the autonomic nervous system imbalance in dystrophic TO-2 hamsters. Electrocardiograms were recorded non-invasively in conscious ~9-month old TO-2 hamsters (n=10 and non-myopathic F1B control hamsters (n=10. Heart rate was higher in TO-2 hamsters than controls (453 ± 12 bpm vs. 311 ± 25 bpm, P<0.01. Time domain heart rate variability, an index of parasympathetic tone, was lower in TO-2 hamsters (12.2 ± 3.7 bpm vs. 38.2 ± 6.8, P<0.05, as was the coefficient of variance of the RR interval (2.8 ± 0.9 % vs. 16.2 ± 3.4 %, P<0.05 compared to control hamsters. Power spectral analysis demonstrated reduced high frequency and low frequency contributions, indicating autonomic imbalance with increased sympathetic tone and decreased parasympathetic tone in dystrophic TO-2 hamsters. Similar observations in newborn hamsters indicate autonomic nervous dysfunction may occur quite early in life in neuromuscular diseases. Our findings of autonomic abnormalities in newborn hamsters with a mutation in the delta-sarcoglycan gene suggest approaches to correct modulation of the heart rate as prevention or therapy for muscular dystrophies.

    In cases where different species might be housed in the same room or secondary enclosure, the Guide for the Care and Use of Laboratory Animals recommends that the animals should be behaviorally compatible and have the same health status. Syrian hamsters and Mongolian gerbils, both desert-dwelling rodents, appear to be reasonable candidates for such a combination. This study was undertaken to evaluate whether housing hamsters and gerbils in the same secondary enclosure is an acceptable practice. Weanling and breeding-age hamsters and gerbils were housed in open-topped cages in an isolator for 5 mo; the isolator also contained with nude and haired mice, which acted as sentinels. Cages housing hamsters and gerbils were rotated between species, and dirty bedding was exchanged between species in an effort to transmit microorganisms. In addition, sentinel mice housed in the isolator were supplied with dirty bedding from both hamsters and gerbils. Neither species showed clinical signs of illness, the health status of neither the hamsters nor the gerbils changed significantly, and the sentinel mice acquired only 2 infectious organisms, a Helicobacter species and Staphylococcus aureus. Both hamsters and gerbils bred successfully when housed together in the same isolator, and no infanticide or mortality was seen. Breeding performance did not differ between isolator breeding and barrier breeding. This study supports the housing of hamsters and gerbils in the same secondary enclosure. PMID:26045450

    Critical comment is provided on the phenomena of couples postponing childbearing in Singapore. In spite of a media campaign to promote childbearing and tax incentives, women are choosing to be DINKS, couples with double incomes and no kids. Women's reasons for not having children are to enjoy more freedom and a better material life and maintain a career. Seet Ai Mee, the junior minister of community development, in 1990 spoke in a public address about women's lack of belief in marriage and the loss of independence and career prospects when children come along. Official concern is based on the rising median age of childbearing which has gone from 23.4 years in 1970 to 27.7 years in 1991. A continuing trend would put women 30 years old at the age of 1st childbearing in the year 2000. 1 of 5 women presently do not have children. 2.9% fewer babies were born in the 1st 10 months of 1991 compared with 1990. The Director of the Population Planning Unite believes that the campaign has been successful in promoting coupling, but not procreation. Examples are given of 4 women who chose not to have children. 1 was a 26-year old university graduate who was a product manager. She is married and thinks that the ad campaign is not appropriately geared to an educated population. Romance and hard sell are out of place. Another psychotherapist expressed the opinion that women wanted a house a car before having children, and later age at childbearing was desired because the desire was to a small family anyway. Freedom has a greater value over the desire for children. A 30-year old writer finds women with children boring, and later age at childbearing means greater maternal maturity. Several examples are given of women who desire an earlier start on childbearing because of the demands placed on older mothers. The director of a counseling and care center defines DINKS as educated higher income people who want a career, personal goals, travel, and other things. There should not be a

  18. The design of high vacuum system for baby electron beam machine (baby ebm): a comparison between theoretical and experimental

    International Nuclear Information System (INIS)

    Baby ebm which was developed to study the engineering and physics of electrons requires the use of high vacuum system in order to prevent electron loss and ionization of air molecules. In selecting the high vacuum system for baby ebm two main factors were considered: the ultimate pressure and the pump down time. The ultimate pressure required for the operation of the baby ebm is in 10-7 torr range. The pump down time was estimated from calculations, taking into account the vacuum pump and chamber size. The turbomolecular pump system (tmp), which is capable of achieving the required vacuum level was selected as the high vacuum system and installed to baby ebm. The tmp is currently fully operational. It was found that the vacuum pumping performance of the tmp differs considerably from what the calculations indicate. Compared to the calculations, it takes a much longer time to achieve the required operating pressure of baby ebm. This could be due to the fact that the formula used for the calculations was a very simplified formula that takes into account the main factors only which are the vacuum pump and chamber size. This paper attempts to present the comparison of the tmp performance between the theoretical and experimental. (Author)

    External carcinogens, such as tobacco and alcohol, induce molecular changes in large areas of oral mucosa, which increase the risk of malignant transformation. This condition, known as 'field cancerization', can be detected in biopsy specimens using histochemical techniques, even before histological alterations are identified. The efficacy of these histochemical techniques as biomarkers of early cancerization must be demonstrated in appropriate models. The hamster cheek pouch oral cancer model, universally employed in biological studies and in studies for the prevention and treatment of oral cancer, is also an excellent model of field cancerization. The carcinogen is applied in solution to the surface of the mucosa and induces alterations that recapitulate the stages of cancerization in human oral mucosa. We have demonstrated that the following can be used for the early detection of cancerized tissue: silver staining of nucleolar organizer regions; the Feulgen reaction to stain DNA followed by ploidy analysis; immunohistochemical analysis of fibroblast growth factor-2, immunohistochemical labeling of proliferating cells to demonstrate an increase of epithelial cell proliferation in the absence of inflammation; and changes in markers of angiogenesis (i.e. those indicating vascular endothelial growth factor activity, endothelial cell proliferation and vascular density). The hamster cheek pouch model of oral cancer was also proposed and validated by our group for boron neutron capture therapy studies for the treatment of oral cancer. Clinical trials of this novel treatment modality have been performed and are underway for certain tumor types and localizations. Having demonstrated the efficacy of boron neutron capture therapy to control tumors in the hamster cheek pouch oral cancer model, we adapted the model for the long-term study of field cancerized tissue. We demonstrated the inhibitory effect of boron neutron capture therapy on tumor development in field

    This paper describes the electron beam detection of Baby EBM. The detection is divided by two categories; beam current measurement and beam positioning under the scanning window. The beam detector system was completely fabricated and tested and the detector was able to detect the electron beam of Baby EBM. It has been found that the beam current of this EBM is 1.62 mA for energy of 0.14 MeV. A higher beam current can be obtained if a proper cooling system to the window foil is installed. (Author)

    We study the baby Skyrme model as a theory that interpolates between two distinct BPS systems. For this, a near-BPS approximation can be used when there is a small deviation from each of the two BPS limits. We provide analytical explanation and numerical support for the validity of this approximation. We then study the set of all possible supersymmetric extensions of the baby Skyrme model with N =1 and the particular ones with extended N =2 supersymmetries and relate this to the above mentioned almost-BPS approximation.

    In present paper we show that many properties of the baby skyrmions, which have been determined numerically, can be understood in terms of an analytic approximation. In particular, we show that this approximation captures properties of the multiskyrmion solutions (derived numerically) such as their stability towards decay into various channels, and that it is more accurate for the "new baby Skyrme model" which describes anisotropic physical systems in terms of multiskyrmion fields with axial symmetry. Some universal characteristics of configurations of this kind are demonstrated, which do not depend on their topological number.

    2,4-Dichlorophenoxyacetic acid (2,4-D), a widely used broadleaf herbicide, is under investigation in a study of peroxisome proliferators. To supplement that study, male and female rats, mice, and hamsters were dosed with 14C-2,4-D orally at 5 and 200 mg/kg and tissue distributions were determined. Blood, liver, kidney, muscle, skin, fat, brain, testes, and ovaries were examined. At early time points tissues from female rats consistently contained higher amounts of radioactivity than did corresponding tissues from males (up to 9 times). By 72 hr, tissue levels were equivalent and males and females had excreted equal amounts of radioactivity. This sex difference was absent in mice. In hamsters, males had higher tissue levels than females. Taurine, glycine, and glucuronide conjugates of 2,4-D were excreted along with parent. Metabolite profiles differed between species qualitatively and quantitatively; however, differences between sexes were minimal. Plasma elimination curves were generated in male and female rats after iv and oral administration. Kinetic analysis revealed significant differences in elimination and exposure parameters consistent with a greater ability to clear 2,4-D by male rats relative to females. This suggests that at equivalent doses, female rats are exposed to higher concentrations of 2,4-D for a longer time than males and may be more susceptible to 2,4-D-induced toxicity. These sex-dependent variations in the clearance of 2,4-D in rats and hamsters may indicate a need for sex-specific models to accurately assess human health risks. PMID:9311622

  8. Kidney development in the first year of life in small-for-gestational-age preterm infants

    Small-for-gestational-age (SGA) infants have been reported to have a significantly reduced number of nephrons that could be a risk factor for development of hypertension later in life. To evaluate kidney size prospectively in relation to other anthropometric parameters during the first year of life in SGA babies. The babies in the study were 31-36 weeks' gestational age (GA) at birth and were matched with control preterm infants of similar GA, but appropriate for gestational age (AGA). The SGA infants were further classified as symmetrical and asymmetrical according to the anthropometric parameters. The total number of measurements in symmetrical SGA preterm infants was 324, in asymmetrical SGA preterm infants 295, and in AGA infants 536. In symmetrical SGA preterm infants (31-36 weeks' GA) mean kidney length (± SD) of 56±4 mm was significantly different from the controls (58.9±4.6 mm) up to 6 months' chronological age (P < 0.05). In the asymmetrical SGA preterm infants, mean kidney length (45.3±4.0 mm) was significantly different from the controls (48.2±4.4 mm) up to 40 weeks' corrected age. At 1 year chronological age, all preterm infants (symmetrical and asymmetrical SGA and AGA) had similar mean kidney length (61.6±4.6, 62.8±4.3, and 62.3±4.0 mm, respectively). The ratio of kidney length to crown-to-heel length was similar in all preterm groups. Kidney length in preterm SGA infants (symmetrical and asymmetrical) follows closely the other auxological parameters during the first year of life. (orig.)

    International Renal Interest Society chronic kidney disease Stage 1 and acute kidney injury Grade I categorizations of kidney disease are often confused or ignored because patients are nonazotemic and generally asymptomatic. Recent evidence suggests these seemingly disparate conditions may be mechanistically linked and interrelated. Active kidney injury biomarkers have the potential to establish a new understanding for traditional views of chronic kidney disease, including its early identification and possible mediators of its progression, which, if validated, would establish a new and sophisticated paradigm for the understanding and approach to the diagnostic evaluation, and treatment of urinary disease in dogs and cats.

  19. Rift Valley fever virus infection in golden Syrian hamsters.

    Directory of Open Access Journals (Sweden)

    Dionna Scharton

    Full Text Available Rift Valley fever virus (RVFV is a formidable pathogen that causes severe disease and abortion in a variety of livestock species and a range of disease in humans that includes hemorrhagic fever, fulminant hepatitis, encephalitis and blindness. The natural transmission cycle involves mosquito vectors, but exposure can also occur through contact with infected fluids and tissues. The lack of approved antiviral therapies and vaccines for human use underlies the importance of small animal models for proof-of-concept efficacy studies. Several mouse and rat models of RVFV infection have been well characterized and provide useful systems for the study of certain aspects of pathogenesis, as well as antiviral drug and vaccine development. However, certain host-directed therapeutics may not act on mouse or rat pathways. Here, we describe the natural history of disease in golden Syrian hamsters challenged subcutaneously with the pathogenic ZH501 strain of RVFV. Peracute disease resulted in rapid lethality within 2 to 3 days of RVFV challenge. High titer viremia and substantial viral loads were observed in most tissues examined; however, histopathology and immunostaining for RVFV antigen were largely restricted to the liver. Acute hepatocellular necrosis associated with a strong presence of viral antigen in the hepatocytes indicates that fulminant hepatitis is the likely cause of mortality. Further studies to assess the susceptibility and disease progression following respiratory route exposure are warranted. The use of the hamsters to model RVFV infection is suitable for early stage antiviral drug and vaccine development studies.

    Thioredoxin (Trx) is a multifunctional redox protein that has growth-promoting and anti-apoptotic effects on cells and protects cells from endogenous and exogenous free radicals. Recently, altered expression of Trx has been reported in various cancers. In the present study, we investigated altered expression of Trx at the precancerous and carcinogenic phases during cholangiocarcinogenesis in a hamster cholangiocarcinoma (ChC) model, using semiquantitative immunohistochemical and Western blot analyses. Moreover, to determine if the results correlated well with those in human ChCs, we carried out a comparative immunohistochemical study for Trx in tissue-arrayed human ChCs with different grades of tumor cell differentiation. Trx was found highly expressed in the cytoplasm of dysplastic bile ducts with highly abnormal growth patterns and ChCs irrespective of tumor type or tumor cell differentiation. Overexpression of Trx at the precancerous and carcinogenic phases was further supported by significant elevation of Trx protein in Western blotting. The results from the hamster ChCs were in good agreement with those from human ChCs. Our results strongly suggested that the redox regulatory function of Trx plays an important role in bile duct cell transformation and tumor progression during cholangiocarcinogenesis. PMID:19799607

    Science.gov (United States)

    Liddle, Mitzi-Jane E; Bradley, Ben S; Mcgrath, Andrew

    2015-01-01

    Empathy is an important competence in our social world, a motivator of prosocial behavior, and thought to develop throughout the second year of life. The current study examined infants' responses to naturalistic peer distress to explore markers of empathy and prosocial behavior in young babies. Seventeen 8-month-old infants participated in a repeated measures design using the "babies-in-groups" paradigm, with maternal presence as the independent variable. Significant differences were found between response types: Gaze was the standard response to infant distress, followed by socially directed behaviors and affect, with self-distress rarely occurring. Maternal presence was not found to impact the nature or frequency of babies' responses to peer distress. During distress episodes, babies looked preferentially at the distressed peer, then other mothers, and least to their own mother. Data revealed that infant responses to peer distress resulted in a successful cessation of that distress episode over one third of the time. Case studies are provided to illustrate the quantitative data. The results provided evidence of empathic concern and prosocial behavior in the first year of life, and provoke a challenge to developmental theories of empathy. PMID:26112352

    Bouquegneau, Antoine; Dubois, Bernard E; Krzesinski, Jean-Marie; Delanaye, Pierre

    2012-08-01

    Anorexia nervosa is a common psychiatric disorder that disproportionately affects adolescents and young adults and is associated with high rates of morbidity and mortality. Anorexia nervosa can affect the kidney in numerous ways, including increased rates of acute kidney injury and chronic kidney disease, electrolyte abnormalities, and nephrolithiasis. Additionally, the diagnosis and treatment of anorexia nervosa-associated kidney diseases are challenging, reflecting complications such as refeeding syndrome, as well as the limitations of serum creatinine level in this population to estimate kidney function and the psychosocial challenges inherent with treating systemic manifestations of psychiatric conditions. In this review, we discuss kidney diseases and kidney-associated conditions that occur in individuals with anorexia nervosa, summarizing many of the challenges in treating patients with this disease.

    Full Text Available To establish an experimental persistent infection of the brain with human adenoviruses, adenovirus type 6 (ad 6 was inoculated intracerebrally into young adult hamsters. Hamsters appeared languid for a few days after inoculation, but recovered rapidly. By cocultivation of tissue fragments with HeLa cells, ad 6 was always recovered from the brains of hamsters throughout their lives, as long as 29 months, indicating the establishment of a lifelong persistent infection. Except for the first few days after inoculation, however, attempts to recover virus by inoculation of tissue extracts onto HeLa cells or by cultivation of tissue fragments alone were unsuccessful.

    A study of the response of rat and hamster to nitrogen dioxide (NO2) under identical conditions has been undertaken. Exposure to 20 parts/IO6 NO2 for 24 h produced a mild cytotoxic effect on the terminal bronchiole and proximal alveoli in the rat, whereas the hamster developed a moderate to severe bronchiolitis and alveolitis. Electron microscopic examination of tissue sections showed accumulation of surfactant in lamellar bodies of the alveolar type II cell in the rat but not in the hamster,...

    Acute selenium (Se) toxicosis was induced in baby pigs by intramuscular (IM) injection of Se, as selenite, using commercially available selenium-vitamin E (Se-E) preparations. Graded amounts of Se were given to 26 pigs from a herd that had not experienced losses from Se-E deficiency and to 136 pigs from a herd that had continual losses from Se-E deficiency. Of the 2 groups of pigs, those from the Se-E-deficient herd were more susceptible to acute Se toxicosis. Clinical signs of toxicosis were vomiting, anorexia, depression, dyspnea, weakness, and coma, with death occurring 24 to 48 hours after injection. Pathologic alterations observed grossly and histologically included pulmonary edema, skeletal myodegeneration, hepatic degeneration and necrosis, transudation into body cavities, and widespread circulatory disturbances. Mean tissue Se concentrations in 20 pigs with acute toxicosis 24 to 48 hours after injection were 12.44 ppm in liver, 1.31 ppm in kidney, and 0.32 ppm in skeletal muscle.

    Full Text Available Kidney transplantation in patients with end stage renal diseaseis preferred to dialysis because transplantation provides a betterquality of life and improved survival. However, the gapbetween the supply and demand for a renal allograft is wideningand the waiting time is increasing. Iranian protocol, a controlledtransplant program supported by the government forliving unrelated donors, was initiated for solving the problemof organ shortage. Although this system might experiencechallenges, clearly it has advantages over other organ procurementsystems primarily that thousands in need do not diewhile waiting for a compatible donor.In the present review I discuss the history of renal transplantationin Iran, "Iranian model" protocol, the situation ofIran’s kidney transplantation from either living or deceaseddonors compared with the Middle East countries, and our experiencesof unrelated renal transplantation.

    Reproduction is a complex and energy demanding function. When internal and external conditions might impair reproductive success (negative energy balance, stress, harsh season) reproductive activity has to be repressed. Recent evidence suggests that these inhibitory mechanisms operate on Kiss1......-expressing neurons, which were recently shown to be implicated in the regulation of GnRH release. Hamsters are seasonal rodents which are sexually active in long photoperiod and quiescent in short photoperiod. The photoperiodic information is transmitted to the reproductive system by melatonin, a pineal...... hormone whose secretion is adjusted to night length. The photoperiodic variation in circulating melatonin has been shown to synchronize reproductive activity with seasons, but the mechanisms involved in this effect of melatonin were so far unknown. Recently we have observed that Kiss1 mRNA level in the...

  16. Photosensitized inactivation of Chinese hamster cells by phthalocyanines

    International Nuclear Information System (INIS)

    Chloroaluminum phthalocyanine was found to sensitize cultured Chinese hamster cells upon exposure to white fluorescent light. Elimination of wavelengths below 370 nm did not reduce the effect significantly, indicating that the effective wavelengths were those absorbed by the Q band (600-700 nm) of phthalocyanine. The magnitude of the photosensitizing effect increased with the dye concentration and the time of its contact with the cells prior to light exposure. Although photosensitization was drastically reduced in the absence of oxygen, the lack of effect of glycerol and D2O during exposure suggests that neither hydroxyl radicals nor 1O2 are responsible for the cytotoxic response. The efficiency of the photosensitized induced cell killing did not vary with the position of the cells in the cell cycle, in contrast to exposure to X-rays. The improved spectral properties, the reported low toxicity and the selective retention by neoplasms, make phthalocyanines promising candidates for use in photodynamic therapy of cancer. (author)

    Full Text Available Abstract Background Mobile phone technologies for health promotion and disease prevention have evolved rapidly, but few studies have tested the efficacy of mobile health in full-fledged programs. Text4baby is an example of mobile health based on behavioral theory, and it delivers text messages to traditionally underserved pregnant women and new mothers to change their health, health care beliefs, practices, and behaviors in order to improve clinical outcomes. The purpose of this pilot evaluation study is to assess the efficacy of this text messaging campaign. Methods We conducted a randomized pilot evaluation study. All participants were pregnant women first presenting for care at the Fairfax County, Virginia Health Department. We randomized participants to enroll in text4baby and receive usual health care (intervention, or continue simply to receive usual care (control. We then conducted a 24-item survey by telephone of attitudes and behaviors related to text4baby. We surveyed participants at baseline, before text4baby was delivered to the intervention group, and at follow-up at approximately 28 weeks of baby’s gestational age. Results We completed 123 baseline interviews in English and in Spanish. Overall, the sample was predominantly of Hispanic origin (79.7% with an average age of 27.6 years. We completed 90 follow-up interviews, and achieved a 73% retention rate. We used a logistic generalized estimating equation model to evaluate intervention effects on measured outcomes. We found a significant effect of text4baby intervention exposure on increased agreement with the attitude statement “I am prepared to be a new mother” (OR = 2.73, CI = 1.04, 7.18, p = 0.042 between baseline and follow-up.

El trasplante renal de donante vivo es una excelente alternativa para el paciente joven en situación de prediálisis porque ofrece mejores resultados. El tratamiento inmunosupresor debe ser individualizado buscando la sinergia inmunosupresora y el mejor perfil de seguridad, y debe adaptarse a las diferentes etapas del trasplante renal. En el seguimiento del trasplante renal hay que tener muy en cuenta los factores de riesgo cardiovascular y los tumores puesto que la muerte del paciente con injerto funcionante es la segunda causa de pérdida del injerto tras el primer año del trasplante. La función alterada del injerto es un factor de mortalidad cardiovascular independiente que requerirá seguimiento y control de todas sus complicaciones para retrasar la entrada en diálisis.The kidney transplant is the therapy of choice for the majority of the causes of chronic terminal kidney insufficiency, because it improves the quality of life and survival in comparison with dialysis. A kidney transplant from a live donor is an excellent alternative for the young patient in a state of pre-dialysis because it offers the best results. Immunosuppressive treatment must be individualised, seeking immunosuppressive synergy and the best safety profile, and must be adapted to the different stages of the kidney transplant. In the follow-up to the kidney transplant, cardiovascular risk factors and tumours must be especially taken into account, given that the death of the patient with a working graft is the second cause of loss of the graft following the first year of the transplant. The altered function of the graft is a factor of independent cardiovascular mortality that will require follow-up and the control of all its complications to postpone the entrance in dialysis.

  19. Fragmentation of kidney stones

    International Nuclear Information System (INIS)

    Complete text of publication follows. Fragmentation, i.e. the breaking of particulate materials into smaller pieces is abundant in nature and underlies several industrial processes, which attracted a continuous interest in scientific and engineering research over the past decades. In industrial applications, fragmentation processes are mostly used for the comminution of ores in various types of mills. Kidney stone is a well known human dis- ease which embitters the life of many people (in a country like the USA about 106 cases are registered yearly). In order to extract large kidney stones (diameter ≥ 1 cm) from the human body without operation, one of the most efficient treatment is the fragmentation of kidney stones by the so-called extracorporal shock wave lithography method: a shock wave penetrating the human body is generated by an electric pulse. The repeated application of the shock wave gradually fragments the stones into pieces of size ≤ 2 mm which then leave the body through the urine system. Recently, a novel type of lithographic method has been suggested by using widely focused shock waves which fragment the stones by a squeezing mechanism. Laboratory experiments showed that the widely focused squeezing waves achieve a higher fragmentation efficiency than the frequently used shock waves of sharp focus. Based on this method a novel medical treatment can be introduced which is less demanding for the patients. Before the application of the method in the clinical practice a detailed understanding of the fragmentation mechanism of kidney stones due to shock waves is required. Since analytic theoretical methods have serious limitations in this field, we develop a realistic model of the mechanical behavior of kidney stones and a simulation code which makes possible to study the mechanism of breakup under various external conditions. Computer simulations in two dimensions have revealed a peculiar way of crack formation, i.e. the crack which finally breaks

    Initial antidepressant treatment can paradoxically worsen symptoms in depressed adolescents by undetermined mechanisms. Interestingly, antidepressants modulate GABAA receptors, which mediate paradoxical effects of other therapeutic drugs, particularly in females. Although the neuroanatomic site of action for this paradox is unknown, elevated GABAA receptor signaling in the nucleus accumbens can disrupt motivation. We assessed fluoxetine's effects on motivated behaviors in pubescent female hamsters - anhedonia in the reward investigational preference (RIP) test as well as anxiety in the anxiety-related feeding/exploration conflict (AFEC) test. We also assessed accumbal signaling by RT-PCR and electrophysiology. Fluoxetine initially worsened motivated behaviors at puberty, relative to adulthood. It also failed to improve these behaviors as pubescent hamsters transitioned into adulthood. Low accumbal mRNA levels of multiple GABAA receptor subunits and GABA-synthesizing enzyme, GAD67, assessed by RT-PCR, suggested low GABAergic tone at puberty. Nonetheless, rapid fluoxetine-induced reductions of α5GABAA receptor and BDNF mRNA levels at puberty were consistent with age-related differences in GABAergic responses to fluoxetine and disruption of the motivational state. Whole-cell patch clamping of accumbal slices also suggested low GABAergic tone by the low amplitude of miniature inhibitory postsynaptic currents (mIPSCs) at puberty. It also confirmed age-related differences in GABAergic responses to fluoxetine. Specifically, fluoxetine potentiated mIPSC amplitude and frequency at puberty, but attenuated the amplitude during adulthood. These results implicate GABAergic tone and GABAA receptor plasticity in adverse motivational responses and resistance to fluoxetine during adolescence. PMID:27068049

  1. Retention of inhaled particles in hamsters with pulmonary fibrosis

    International Nuclear Information System (INIS)

    Aerosol retention was studied in hamsters 30, 60, and 90 days after the initiation of interstitial pulmonary fibrosis by a combination of bleomycin (bleo), 0.16 U/100 g body weight given intratracheally, and O2, for 72 h. Groups of bleo-O2-treated and control animals were exposed (awake) for 25 min to a 99mTc-labeled insoluble aerosol (activity median aerodynamic diameter, 0.45 micron; geometric standard deviation, 1.3). Within 5 min after exposure, the hamsters were killed and their lungs were excised and dried at total lung capacity, and sliced into 1-mm sections. Slices were dissected into pieces, and an evenness index (EI) was calculated for each piece (formula: see text). With uniformity of retention, all Els would be 1. The distribution of Els in control animals had a mean of 1.0 and a SD of 0.27; 0% of the Els were less than or equal to 0.20. Total retention diminished and was less uniform in bleo-O2-treated animals. At 30 days, the SD increased to 0.62, and 6% of the Els were less than or equal to 0.20. At 60 and 90 days, nonuniformity decreased but was still greater than that in the control animals (SD60 . 0.42, SD90 . 0.36). When examined histologically, individual pieces with low Els had more disease than those with high Els. Local decreases in compliance caused by fibrosis may have altered regional ventilation and retention. Our data also correlate with the progression of fibrosis from a focal lesion at 30 days to a more diffuse lesion at 90 days

  2. Photoperiod Regulates vgf-Derived Peptide Processing in Siberian Hamsters.

    Directory of Open Access Journals (Sweden)

    Barbara Noli

    Full Text Available VGF mRNA is induced in specific hypothalamic areas of the Siberian hamster upon exposure to short photoperiods, which is associated with a seasonal decrease in appetite and weight loss. Processing of VGF generates multiple bioactive peptides, so the objective of this study was to determine the profile of the VGF-derived peptides in the brain, pituitary and plasma from Siberian hamsters, and to establish whether differential processing might occur in the short day lean state versus long day fat. Antisera against short sequences at the C- or N- termini of proVGF, as well as against NERP-1, TPGH and TLQP peptides, were used for analyses of tissues, and both immunohistochemistry and enzyme linked immunosorbent assay (ELISA coupled with high-performance liquid (HPLC or gel chromatography were carried out. VGF peptide immunoreactivity was found within cortex cholinergic perikarya, in multiple hypothalamic nuclei, including those containing vasopressin, and in pituitary gonadotrophs. ELISA revealed that exposure to short day photoperiod led to a down-regulation of VGF immunoreactivity in the cortex, and a less pronounced decrease in the hypothalamus and pituitary, while the plasma VGF levels were not affected by the photoperiod. HPLC and gel chromatography both confirmed the presence of multiple VGF-derived peptides in these tissues, while gel chromatography showed the presence of the VGF precursor in all tissues tested except for the cortex. These observations are consistent with the view that VGF-derived peptides have pleiotropic actions related to changing photoperiod, possibly by regulating cholinergic systems in the cortex, vasopressin hypothalamic pathways, and the reproductive axis.

  3. Study of radiation effects on DMBA induced hamster lingual carcinoma

    International Nuclear Information System (INIS)

    A morphological and histo-pathological study of DMBA-induced carcinoma of the tongue in hamsters was carried out. The tongues of eighty golden hamsters were coated with a 1% DMBA acetone solution three times a week to induce carcinoma. The ulceration rate was about 100% in three to five months, and the ulceration process was followed by microangiography using Hayashi's drawing ink. Papillomatous or carcinomatous tongues were irradiated once with 60Co-γ rays. The total absorption dosage was 2000 rad. Then 67Ga-citrate and 57Co-bleomycin (57Co-BLM), were injected into the abdominal cavity. The amount of uptake of the reagents by the tumor was clearly low on three days after irradiation and increased on ten days after irradiation. This variation was more remarkable in the case of carcinoma than in the case of papilloma. 67Ga-citrate concentration ratio of carcinoma-to-organ and of papilloma-to-organ was the same as 57Co-BLM concentration ratio of carcinoma-to-organ and of papilloma-to-organ. Vascular changes was observed by means of microangiography, and the ratio of vascular area was measured by an image analyzer. The ratio increased rapidly with expansion of the tumor vessel and the exuding of contrast media one day after irradiation, decreased with damage of the vessel neighboring the tumor two days after irradiation, slightly increased with the development of a minimal vessel in the neighborhood of tumor three days after irradiation, and slightly decreased with the death at the center of tumor on ten days. These morphological variations of the tumor vessel were closely related to those of labeled tumor seekers. (Nakanishi, T.)

    2011-02-01

    Full Text Available Abstract Avian paramyxoviruses (APMVs are frequently isolated from domestic and wild birds throughout the world and are separated into nine serotypes (APMV-1 to -9. Only in the case of APMV-1, the infection of non-avian species has been investigated. The APMVs presently are being considered as human vaccine vectors. In this study, we evaluated the replication and pathogenicity of all nine APMV serotypes in hamsters. The hamsters were inoculated intranasally with each virus and monitored for clinical disease, pathology, histopathology, virus replication, and seroconversion. On the basis of one or more of these criteria, each of the APMV serotypes was found to replicate in hamsters. The APMVs produced mild or inapparent clinical signs in hamsters except for APMV-9, which produced moderate disease. Gross lesions were observed over the pulmonary surface of hamsters infected with APMV-2 & -3, which showed petechial and ecchymotic hemorrhages, respectively. Replication of all of the APMVs except APMV-5 was confirmed in the nasal turbinates and lungs, indicating a tropism for the respiratory tract. Histologically, the infection resulted in lung lesions consistent with bronchointerstitial pneumonia of varying severity and nasal turbinates with blunting or loss of cilia of the epithelium lining the nasal septa. The majority of APMV-infected hamsters exhibited transient histological lesions that self resolved by 14 days post infection (dpi. All of the hamsters infected with the APMVs produced serotype-specific HI or neutralizing antibodies, confirming virus replication. Taken together, these results demonstrate that all nine known APMV serotypes are capable of replicating in hamsters with minimal disease and pathology.

  13. Use of hamster as a model to study diet-induced atherosclerosis

    Lichtenstein Alice H

    2010-12-01

    Full Text Available Abstract Golden-Syrian hamsters have been used as an animal model to assess diet-induced atherosclerosis since the early 1980s. Advantages appeared to include a low rate of endogenous cholesterol synthesis, receptor-mediated uptake of LDL cholesterol, cholesteryl ester transfer protein activity, hepatic apoB-100 and intestinal apoB-48 secretion, and uptake of the majority of LDL cholesterol via the LDL receptor pathway. Early work suggested hamsters fed high cholesterol and saturated fat diets responded similarly to humans in terms of lipoprotein metabolism and aortic lesion morphology. Recent work has not consistently replicated these findings. Reviewed was the literature related to controlled hamster feeding studies that assessed the effect of strain, background diet (non-purified, semi-purified and dietary perturbation (cholesterol and/or fat on plasma lipoprotein profiles and atherosclerotic lesion formation. F1B hamsters fed a non-purified cholesterol/fat-supplemented diet had more atherogenic lipoprotein profiles (nHDL-C > HDL-C than other hamster strains or hamsters fed cholesterol/fat-supplemented semi-purified diets. However, fat type; saturated (SFA, monounsaturated or n-6 polyunsaturated (PUFA had less of an effect on plasma lipoprotein concentrations. Cholesterol- and fish oil-supplemented semi-purified diets yielded highly variable results when compared to SFA or n-6 PUFA, which were antithetical to responses observed in humans. Dietary cholesterol and fat resulted in inconsistent effects on aortic lipid accumulation. No hamster strain was reported to consistently develop lesions regardless of background diet, dietary cholesterol or dietary fat type amount. In conclusion, at this time the Golden-Syrian hamster does not appear to be a useful model to determine the mechanism(s of diet-induced development of atherosclerotic lesions.

    Sexual behavior is a natural reward for many rodent species, and it often includes chemosensory-directed components. Chemosensory stimuli themselves may also be rewarding. Conditioned place preference (CPP) is one paradigm frequently used to test the rewarding properties of a range of stimuli. Males and females of several rodent species show a CPP for sexual behavior, however, it is currently unknown whether sexual behavior can induce a CPP in male Syrian hamsters. As male Syrian hamsters are...

    Both the light-dark cycle and the timing of food intake can entrain circadian rhythms. Entrainment to food is mediated by a food entrainable circadian oscillator (FEO) that is formally and mechanistically separable from the hypothalamic light-entrainable oscillator. This experiment examined whether seasonal changes in day length affect the function of the FEO in male Siberian hamsters (Phodopus sungorus). Hamsters housed in long (LD; 15 h light/day) or short (SD; 9 h light/day) photoperiods w...

    Microbiological analysis of several cold-preserved tissue samples from the Siberian baby mammoth known as Lyuba revealed a number of culturable bacterial strains that were grown on anaerobic media at 4 C. Lactic acid produced by LAB (lactic acid bacteria) group, usually by members of the genera Carnobacterium and Lactosphera, appears to be a wonderful preservative that prevents other bacteria from over-dominating a system. Permafrost and lactic acid preserved the body of this one-month old baby mammoth and kept it in exceptionally good condition, resulting in this mammoth being the most complete such specimen ever recovered. The diversity of novel anaerobic isolates was expressed on morphological, physiological and phylogenetic levels. Here we discuss the specifics of the isolation of new strains, differentiation from trivial contamination, and preliminary results for the characterization of cultures.

    Microbiological analysis of several cold-preserved tissue samples from the Siberian baby mammoth known as Lyuba revealed a number of culturable bacterial strains that were grown on anaerobic media at 3 oC. Lactic acid produced by LAB (lactic acid bacteria) group, usually by members of the genera Carnobacterium and Lactosphera, appears to be a wonderful preservative that keeps other bacteria from colonizing a system. Permafrost and lactic acid preserved the body of this one month-old baby mammoth and kept it in exceptionally good condition, resulting in this mammoth being the most complete sample of the species ever recovered. The diversity of novel psychrophilic anaerobic isolates was expressed on morphological, physiological and phylogenetic levels.

    2015-03-01

    Breast feeding improves important outcomes for mothers and infants. In the UK, breastfeeding rates have historically been low, particularly among socially disadvantaged young women. Although there have been gradual increases in breastfeeding initiation rates since 2000, rates of exclusive breast feeding and continuation until 6 months remain lower than those in similar countries. This review summarises the evidence for effective and cost-effective strategies to help women, particularly those in low income groups, make informed choices, overcome barriers and establish and maintain breast feeding. We describe the development and impact of the Unicef Baby Friendly Initiative, and the roles and responsibilities, and challenges and opportunities that clinicians have in promoting breast feeding and maintaining a baby-friendly culture and environment.

  2. Autoradiographic localization of tritiated dihydrotestosterone in the flank organ of the albino hamster

    International Nuclear Information System (INIS)

    In the hamster flank organ, the growth of hair and growth of sebaceous glands are androgen-dependent functions. Although dihydrotestosterone (DHT) is known to be a potent stimulator of flank organ growth, there is no information about localization of DHT receptor sites in this organ. The purpose of this study was to use steroid autoradiography to localize DHT receptors in the hamster flank organ. Because steroid hormones are functional when translocated to nuclear receptors, nuclear localization by autoradiography defines receptor sites. In order to be able to visualize autoradiographic grains from radiolabeled androgens around hair follicles, albino hamsters were studied to avoid confusion between the grains and pigment granules which are abundant in the more common Golden Syrian hamster. Mature male hamsters castrated 24 hours earlier were given tritium-labeled dihydrotestosterone ( [3H]DHT). Using the technique of thaw-mount steroid autoradiography, 4-micron unfixed frozen sections were mounted in the dark onto emulsion-coated glass slides and allowed to develop for 4-6 months. [3H]DHT was found to be concentrated over sebocyte nuclei. The label was present peripherally as well as in differentiating sebocytes. There was no nuclear localization of [3H]DHT in animals pretreated with excessive quantities of unlabeled DHT. Steroid metabolites of [3H] DHT were assessed by thin-layer chromatography in paired tissue samples. Most of the label remained with DHT. Uptake was inhibited in the flank organ of hamsters pretreated with unlabeled DHT

    Polyphenols in noni juice (NJ) are mainly composed of phenolic acids, mainly gentisic, p-hydroxybenoic, and chlorogenic acids. To investigate the beneficial effects of NJ on the liver, hamsters were fed with two diets, normal-fat and high-fat diets. Furthermore, high-fat dietary hamsters were received distilled water, and 3, 6, and 9 mL NJ/kg BW, respectively. After a 6-week feeding period, the increased (p<0.05) sizes of liver and visceral fat in high-fat dietary hamsters compared to the control hamsters were ameliorated (p<0.05) by NJ supplementation. NJ also decreased (p<0.05) serum/liver lipids but enhanced (p<0.05) daily faecal lipid/bile acid outputs in the high-fat dietary hamsters. High-fat dietary hamsters supplemented with NJ had higher (p<0.05) liver antioxidant capacities but lowered (p<0.05) liver iNOS, COX-2, TNF-α, and IL-1β expressions, gelatinolytic levels of MMP9, and serum ALT values compared to those without NJ. Hence, NJ protects liver against a high-fat dietary habit via regulations of antioxidative and anti-inflammatory responses. PMID:23578611

    The golden hamster (Mesocricetus auratus) is a popular laboratory animal and is used in a multitude of behavioural studies. However, it has been shown that it suffers from different forms of hereditary hydrocephalus, which may result in behavioural changes. This prospective study was designed to look into the usefulness of electroencephalography (EEG) measurements in the diagnosis of hydrocephalus in hamsters. The EEGs of the hydrocephalic hamsters were evaluated double-blind and showed a high-voltage slow wave activity, with a fast activity superimposed onto it. This pattern has already been well described in other hydrocephalic species and differed significantly from the EEGs that were obtained from the normal hamsters. It was concluded from our study that a background activity with an amplitude over 50 muV in combination with a frequency of < or =5 Hz was highly indicative of hydrocephalus in young hamsters. We believe that the EEG could be a very useful diagnostic tool in the screening for hydrocephalus in hamsters. PMID:18435879

    In newborn babies with congenital renal pathology type agenesia, dysplasia or obstruction is very important to know if there is intrautero vicariant growing of the contralateral kidney. To find out that we have proceeded to be ultrasound volume measurement of the normal renal unit, as this is a valuable parameter related to compensatory mechanisms. We have studied by ultrasounds 28 renal units (16 right, 12 left) in newborns with contralateral pathology: pyeloureteral stenosis in 10 cases, multicystic kidney in 13 cases, renal agenesia in 3 cases, obstructive ureterocele in 1 case and another one with ureterovesical stenosis. We considered renal function, length of the larger renal axis width and depth of the kidney mass. Renal function was normal in all cases. Analysis of objectives results show a clear difference between the volume of normal Kidneys in children with contralateral pathology and the control group constituted by 42 renal unit in normal newborns without urological pathology. We conclude with the real evidence of compensatory growing of the normal contralateral kidney during intrautero periods. PMID:7999515

    Dietary data from a nationally representative survey indicate about 80% of US toddlers aged 1-3 years consume too much dietary sodium, which can influence their preference for salty foods in later life. Information on consumer attitudes can inform strategies to reduce sodium in baby and toddler foods. Data were obtained from a 2012 online survey sent to a sample of 11636 US adults aged ≥18 years enrolled in a national probability-based consumer panel; 6378 completed the survey and had non-missing responses to the question of interest, "It is important for baby and toddler foods to be low in sodium." Prevalence of agreement was estimated. Logistic regression was used to describe associations of respondent characteristics with agreement. The majority of respondents were non-Hispanic white and had a household income ≥$60,000. About 7 in 10 (68%, 95% CI: 66%-70%) respondents agreed it is important for baby or toddler foods to be low in sodium. More than 6 of 10 respondents in most subgroups agreed. Among parents with a child currently aged sex, age, race-ethnicity, agreement was most strongly associated with being a parent of a child <2 years, thinking sodium was harmful, and watching/reducing sodium intake (adjusted odds ratios ≥ 2.5, 95% CI's ≠1.0). The majority of respondents including most parents agreed it is important for baby and toddler foods to be low in sodium, suggesting wide consumer support for strategies to lower sodium in these foods.

    While situation theory and situation semantics provide an appropriate framework for a realistic model-theoretic treatment of natural language, serious thinking on their `computational' aspects has only recently started. Existing proposals mainly offer a Prolog- or Lisp-like programming environment with varying degrees of divergence from the ontology of situation theory. In this paper, we introduce a computational medium (called BABY-SIT) based on situations. The primary motivation underlying ...

    We show that the dynamical realization of the acceleration-enlarged Galilean symmetry leads to nonrelativistic massless particles whose energy may be negative. We present a fluid mechanical generalisation of this observation and use it to contruct a nonrelativistic two-dimensional fluid model which possesses solutions with a negative energy density. Considering this model as describing dark energy in a baby universe (two space dimensions) we show that its negative energy density leads to a re...

    Full Text Available Shaken Baby Syndrome refers to the violent and repetitive shaking of an infant, and is a form of abusive head trauma. It was first described in 1974, and has since been the topic of intensive study and discussion. The syndrome has classically been diagnosed with a triad of injuries, namely subdural haemorrhage, retinal haemorrhage and encephalopathy (brain abnormalities. However, recent publications have led to some doubt regarding the causation and diagnostic significance of the triad. It is now generally accepted that other conditions, even natural diseases, may cause the findings listed in the so-called "triad". To date, no reported case law is available on Shaken Baby Syndrome in South Africa; therefore this article focuses on cases in the United States and United Kingdom to delineate some of the issues associated with litigating the condition. This includes the obligation of expert witnesses to give independent, factual evidence about their areas of expertise. It is recommended that medical and legal professionals involved in cases of alleged child abuse should collect as much information as possible about the context of the case. Confessions by parents or caregivers should be treated with circumspection. Awareness campaigns should be aimed at informing the public of the dangers of shaking an infant. And with regards to Shaken Baby Syndrome an increased focus on evidence-based medicine is necessary to dissipate the uncertainty around the condition.

    2014-04-01

    Full Text Available This essay approaches the intimacy between the aesthetic and poetic dimensions of language in the context of nursery school and proposes a phenomenological listening of encounters between adults and babies through the experience of music as a playful action of the expressive body in the world. Considering that without aesthetics life lacks flavor and without poetics it lacks sense, the article focuses on the merleaupontian understanding of the sensitive body as the primary source of significance to assert the inseparability between sensitive and intelligible in the action of learning to co-exist. The educational intention is to claim another rationality to stand up to the simplifying trend in encounters between adults and babies with the plurality of ways of interacting in language. Thus, thinking the aesthetic and poetic event - in the sense of poiesis and aisthesis terms - the link between sound and silence with life taken as its reflexive starting point - not what the baby does but how he experiences what he does in the musical encounters in nursery school. This study allows us to assert the vital and playful power of the expressive body feeling itself and the world in the plurality of ways of being in language that empowers everyday life through acting, producing, creating, doing.

    Kidneys' imaging provides useful information in acute kidney injury (AKI) diagnosis and management. Today, several imaging techniques give information on kidneys anatomy, urinary obstruction, differential diagnosis between AKI and chronic kidney disease (CKD), renal blood flow and glomerular filtration rate. Ultrasound is a safe, non-invasive and repeatable imaging technique so it is widely used in the first level work-up of AKI. The utility of contrast-enhanced computed tomography and magnetic resonance imaging in AKI or in AKI during CKD is limited because of renal toxicity associated with contrast agents used. PMID:27169556
