    The mink is a strict carnivore and a seasonal breeder, which may be used as an experimental model for other carnivores. The present investigation comprised a total of 44 balance experiments, each including a 24-h measurement of heat production by indirect calorimetry, carried out from mating until close to parturition. For observations with a nonprotein respiratory quotient between 0.7 and 1.0 (n = 42), quantitative oxidation of nutrients was calculated. The weight gain of the uterus during pregnancy was studied in 41 females killed either before mating, before implantation, after implantation or in mid or late true gestation, and energy retention was calculated. Heat production did not increase with advancing stage of gestation. Mean energy retention was low and in some individuals with repeated measurements even negative, indicating that part of the energy requirement for pregnancy may be supplied by mobilization of body reserves. This was reflected by a high level (42%) of fat oxidation in relation to total heat production. Protein oxidation accounted for 38% of heat production. The weight gain of the uterus during pregnancy could be described by logarithmic functions. Energy deposition in fetal tissue was low and only averaged approximately 350 kJ 47 d after mating.

    Of 138 wild mink (Mustela vison) from eastern Minnesota, 27% contained Dioctophyma renale, primarily in the right kidney. No significant difference between prevalence in adult male and immature male mink was found, nor between the prevalence in males versus female mink. Thirteen worms were found in one male mink, representing the highest documented infection intensity of a single wild mink.

    2008-01-01

    Examination of 110 Mink (Mustela vison) carcasses from 1998 through 2007 indicated that the giant kidney worm, Dioctophyma renale, occurred in Pine and Kanabec Counties of eastern Minnesota with annual prevalences of 0-92%. Worm prevalence increased from 20% in 1999 to 92% in 2001 and decreased to 6% in 2005. During 2000 to 2007, no worms were found in Mink from Anoka and Chisago Counties (n = 54), and in 2000, none in 107 Mink from LeSeur, Freeborn, Redwood, Brown and Watonwan Counties. Changes in kidney worm prevalence were positively related to trapping success, considered an index of Mink density.

    Two feeding trials were done to study the susceptibility of mink (Mustela vison) to multiple sublethal doses of aflatoxins. In the 1st trial, twenty 3-month-old male mink were divided equally among groups. Each mink in groups 1, 2, 3, and 4 was given a meatball daily that contained 15, 30, 45, or 0 mug of aflatoxins (B1:G1, 40:60), respectively. All mink in group 3 died between the 25th and the 30th days of the feeding trial. Each mink had ingested 1,035 to 1,480 mug of aflatoxins. Four of the mink in group 2 died almost as soon as did mink in group 3. Four mink in group 1 died between 40 and 59 days after the start of the feeding trial. Generally, a marked increase in plasma cholesterol and alkaline phosphatase activity appeared before mink died. The liver from animals that died of aflatoxicosis showed prominent pathologic changes which included hemorrhages and appearance of pink yellow spots. Histopathologic examination of liver from dead mink revealed fatty infiltration, bile duct proliferation, bile stasis, pseudotubular formation, congestion, and fibrosis. The feeding trial was repeated with 20 mink (8 males and 12 females) that were 1.5 to 2 years old. In this instance, 0, 20, 40, and 60 mug of aflatoxins were administered each day. All treated animals, except 1, were dead within 37 days after the experiment started. The survivor was given the lowest dosage of toxins and died after 52 days by which time 960 mug of aflatoxins were consumed. Plasma cholesterol content and alkaline phosphatase activity generally were similar to those observed in younger mink of the 1st feeding trial.

  5. Canine distemper of vaccine origin in European mink, Mustela lutreola--a case report.

    Cases of canine distemper (CD) related to vaccination of exotic carnivores extend over three decades and have been described in at least nine different species. Our report describes a case of acute CD in a European mink, Mustela lutreola, vaccinated with live attenuated CD vaccine licensed for use in fur-farmed mink. The male mink died of an acute grey matter disease with an unusually long incubation period. A female vaccinated at the same time showed no obvious signs of illness. The diagnosis was confirmed by reverse transcriptase-polymerase chain reaction (RT-PCR) and by subsequent sequencing of the PCR products. The sequenced products of the virus isolated from the mink and of the vaccine batch showed 100% identity. This is the first report in which molecular methods were used to confirm that the disease was caused by the vaccine strain. Based on our findings, it is clearly evident that current CD vaccines cannot be safely used in exotic species.

  6. Stress and stereotypic behaviour in mink (Mustela vison)

    We examined whether female mink with low (LS) and high (HS) occurrence of stereotypic behaviour differ in their adrenocortical activity in baseline conditions or in response to immobilisation (Experiment 1), handling, adrenocorticotropic hormone (ACTH) challenge (Experiment 2) and excretion...... 4-20 h after the handling (P = 0.001). In Experiment 3 (n = 16), the excretion of infused (3)H-cortisol did not differ between LS and HS mink. Stereotypic behaviour is concurrent with higher baseline concentrations of FCM, which cannot be explained by a greater adrenocortical reactivity...... or a different excretion of the circulating cortisol. Instead, we conclude that mink with a high level of stereotypic behaviour have a greater perception of stress, or increased sensitivity to stressors at the pituitary level....

    Between 1998 and 2001, mortalities due to verrucous endocarditis were experienced at several mink farms. Gram-positive cocci were isolated from the endocardium of all the animals examined but not always from other internal organs. Almost all the isolates were identified as Streptococcus bovis...

  8. A study of tobacco carcinogenesis XLVIII. Carcinogenicity of N'-nitrosonornicotine in mink (Mustela vison).

    During tobacco processing and smoking, nicotine and nornicotine give rise to N'-nitrosonornicotine (NNN), a highly abundant, strong carcinogen. NNN is known to exert carcinogenic activity in mice, rats and hamsters. Major target organs for NNN carcinogenicity in the rat are the esophagus and the nasal mucosa, and in the Syrian golden hamster trachea and nasal mucosa. In comparison with the rat, the mink (Mustela vison) has a markedly expanded nasal mucosa. Therefore, we explored in this study whether the mink could serve as a non-rodent model for nasal carcinogenesis using NNN as the carcinogen. Twenty random-bred mink, beginning at the age of 3 weeks, received twice weekly s.c. injections of NNN, a total dose of 11.9 mM per animal over a 38 week period. All of the 19 mink at risk developed malignant tumors of both the respiratory and the olfactory region of the nose within 3.5 years. In most animals the malignant tumors, primarily esthesioneuroepithelioma, invaded the brain. Remarkably, NNN induced no other tumors in the mink. None of the control animals developed nasal tumors nor tumors at other sites during the 3.5 years of the assay. The historical data from the farm did not reveal any spontaneous occurrence of nasal tumors in mink at any age. This study supports the concept that NNN is a proven carcinogen for multiple species of mammals and that the mink can serve as a non-rodent, non-inbred animal model for nasal carcinogenesis, especially since NNN induces only tumors in the nasal cavity in this species and not at other sites, as it does in mice, rats and hamsters.

    The aim of the present study was to examine the reproductive effects of two perorally applied phytoestrogens, genistein (8 mg/kg/day) and β-sitosterol (50 mg/kg/day), on the mink (Mustela vison) at human dietary exposure levels. Parental generations were exposed over 9 months to these phytoestrogens and their offspring were exposed via gestation and lactation. Parents and their offspring were sampled 21 days after the birth of the kits. Sex hormone levels, sperm quality, organ weights, and development of the kits were examined. The exposed females were heavier than the control females at the 1st postnatal day (PND). The control kits were heavier than the exposed kits from the 1st to the 21st PND. Phytoestrogens did not affect the organ weights of the adult minks, but the relative testicular weight of the exposed kits was higher than in the control kits. The relative prostate weight was higher and the relative uterine weight lower in the β-sitosterol-exposed kits than in the control kits. Moreover, the plasma dihydrotestosterone levels were lower in the genistein-exposed male kits compared to the control male kits. This study could not explain the mechanisms behind these alterations. The results indicate that perinatal phytoestrogen exposures cause alterations in the weight of the reproductive organs of the mink kits

  10. Naturally occurring Influenza A virus subtype H1N2 infection in a Midwest United States mink (Mustela vison) ranch.

    Influenza A virus (FLUAV) causes acute respiratory disease in humans and a variety of animal species. The virus tends to remain within the species of origin; nonetheless, naturally occurring cross-species transmission of FLUAV has been periodically documented. Multiple cross-species transmissions of FLUAV have been reported from companion animals and captive wild animals, neither of which is historically considered as natural hosts of FLUAV. In the fall of 2010, mink (Mustela vison) inhabiting a 15,000-head mink farm in the Midwest United States experienced persistent severe respiratory distress and nose and/or mouth bleeding. Mink losses averaged approximately 10 animals per day. Six dead mink at 6 months of age were submitted to the Iowa State University Veterinary Diagnostic Laboratory for diagnostic investigation. Gross and microscopic examinations revealed that all 6 mink had hemorrhagic bronchointerstitial pneumonia. Hemolytic Escherichia coli was isolated from lungs, probably accounting for hemorrhagic pneumonia. All animals tested negative for Canine distemper virus and Aleutian mink disease virus. Interestingly, FLUAV of H1N2 subtype, which contained the matrix gene of swine lineage, was detected in the lungs. Serological follow-up on mink that remained in the ranch until pelting also confirmed that the ranch had been exposed to FLUAV of H1 subtype (δ clade). The case study suggests that FLUAV should be included in the differential diagnosis when mink experience epidemics of respiratory disease. Since the source of FLUAV appeared to be uncooked turkey meat, feeding animals fully cooked ration should be considered as a preventive measure.

    Full Text Available This study describes the autumn-winter diet of three carnivores (Mustela lutreola, Lutra lutra and Genetta genetta in northern Spain. Diet composition was analysed from 85 European mink, 156 otter and 564 spotted genet fecal samples The European mink diet was based on small mammals (relative frequency of occurrences 38.1%, fish (30.9% and birds (16.7%. Spotted genet consumed mainly small mammals, birds and fruits, whilst otter predated practically only fish (95%. Using Levins’ index, trophic-niche widths in European mink, small-spotted genet and Eurasian otter were 3.76, 3.77 and 1.10, respectively. The trophic niche overlap by Pianka index for autumn-winter was 0.77 for European mink vs. Small-spotted genet, and 0.60 for European mink vs. otter. The average size of brown trout taken by otter was larger than those consumed by European mink.

    One hundred and ninety-five mink sera randomly selected from 17 Danish mink farms were evaluated for the presence of Toxoplasma gondii antibodies in the latex agglutination test. Six (3%) sera contained T. gondii antibodies in titres of 1:64 or more. The estimated 3% prevalence means that 300 000...... mink out of a total mink population of ten million might be infected with Toxoplasma gondii. This large number of possible sero-positive mink in Denmark indicates that there exists a potential risk of acquiring toxoplasmosis by pelting mink....

  13. Two avian H10 influenza A virus strains with different pathogenicity for mink (Mustela vison).

    Science.gov (United States)

    Englund, L; Hård af Segerstad, C

    1998-01-01

    We compared two strains of avian influenza A viruses of subtype H10 by exposing mink to aerosols of A/mink/Sweden/3,900/84 (H10N4) naturally pathogenic for mink, or A/chicken/Germany/N/49, (H10N7). Lesions in the respiratory tract during the first week after infection were studied and described. Both virus strains caused inflammatory reactions in the lungs and antibody production in exposed mink but only mink/84 virus was reisolated. The lesions caused by mink/84 virus were more severe with higher area density of pneumonia, lower daily weight gain, and more virus in the tissues detected by immunohistochemistry. The results indicate that mink/84 (H10N4), but not chicken/49 virus (H10N7), established multiple cycle replication in infected cells in the mink.

    Total mercury (Hg) concentrations were measured in the fur, brain and liver of wild mink (Mustela vison) and river otters (Lontra canadensis) collected from eastern and Atlantic Canada. Total Hg concentrations in fur were strongly correlated with levels in the brain and liver. There was no difference in tissue concentrations between male and female mink; however, female otters had significantly higher fur, brain and liver Hg levels than males. Similarly, there was not a significant relationship between Hg concentration and age of mink, whereas in otters, Hg concentrations in all three tissues decreased significantly with age. In both species, only a very small percentage of the variability in Hg concentration was explained by age. After adjusting the data for site-to-site differences in Hg levels, Hg concentrations in the fur of mink infected by the parasite, Dioctophyma renale, were found to be significantly higher than Hg levels in uninfected mink.

  15. Disease-associated prion protein in neural and lymphoid tissues of mink (Mustela vison) inoculated with transmissible mink encephalopathy.

    Transmissible spongiform encephalopathies (TSEs) are diagnosed by immunodetection of disease-associated prion protein (PrP(d)). The distribution of PrP(d) within the body varies with the time-course of infection and between species, during interspecies transmission, as well as with prion strain. Mink are susceptible to a form of TSE known as transmissible mink encephalopathy (TME), presumed to arise due to consumption of feed contaminated with a single prion strain of ruminant origin. After extended passage of TME isolates in hamsters, two strains emerge, HY and DY, each of which is associated with unique structural isoforms of PrP(TME) and of which only the HY strain is associated with accumulation of PrP(TME) in lymphoid tissues. Information on the structural nature and lymphoid accumulation of PrP(TME) in mink is limited. In this study, 13 mink were challenged by intracerebral inoculation using late passage TME inoculum, after which brain and lymphoid tissues were collected at preclinical and clinical time points. The distribution and molecular nature of PrP(TME) was investigated by techniques including blotting of paraffin wax-embedded tissue and epitope mapping by western blotting. PrP(TME) was detected readily in the brain and retropharyngeal lymph node during preclinical infection, with delayed progression of accumulation within other lymphoid tissues. For comparison, three mink were inoculated by the oral route and examined during clinical disease. Accumulation of PrP(TME) in these mink was greater and more widespread, including follicles of rectoanal mucosa-associated lymphoid tissue. Western blot analyses revealed that PrP(TME) accumulating in the brain of mink is structurally most similar to that accumulating in the brain of hamsters infected with the DY strain. Collectively, the results of extended passage in mink are consistent with the presence of only a single strain of TME, the DY strain, capable of inducing accumulation of PrP(TME) in the lymphoid

    Using anatomical as well as radiographic and tomographic methods, sixty brains of the N. American mink were examined. It was found that the brain consists of four ventricles. Also, it was noted that the posterior horn was missing and that there was the olfactory recess present in the lateral ventricle, a large-size interthalamic connection present in the third ventricle, and a flat, necklace-like bottom in the fourth ventricle. Only recently, this ins and outs of the mink`s anatomical structure have begun to absorb anatomists. Apparently, it is related to the fact that furry animals, among them the mink, are being domesticated as if ``before our eyes``. For this reason and because of the easy access to material, examining of the brain ventricles in the mink was taken up. (author). 14 refs, 13 figs.

    Mercury (total and methyl), cadmium and selenium concentrations were measured in liver, kidney and brain tissue from mink trapped from the Yukon Territory from 2001-2002. None of these metals was found at levels of toxicological concern. Total mercury averaged 0.66, 0.92 and 0.22 {mu}g g{sup -1} in mink kidney, liver and brain tissue respectively, while methyl mercury averaged 0.77, 0.85 and 0.21 {mu}g g{sup -1} in the same tissues. Selenium averaged 2.07, 1.40 and 0.39 {mu}g g{sup -1} in mink kidney, liver and brain tissue, while cadmium was only measured in kidneys and averaged 0.22 {mu}g g{sup -1}. All element concentrations are presented on a wet weight basis. Concentrations of total mercury in all tissues were significantly higher in female than male mink, possibly reflecting proportionally greater food consumption by the smaller females. Total mercury concentrations were inversely related to the proportion of mercury present as methylmercury, and positively related to concentrations of selenium, consistent with increasing demethylation of methylmercury, and the formation of mercuric selenide as total concentrations of mercury increased. This relationship was seen most strongly in mink liver, less so in kidneys and not at all in brains where most of the mercury was maintained in the methyl form. There did not appear to be any geographical areas in which mink had obviously higher concentrations of mercury, and there was frequently a relatively large range of mercury levels found in mink from a given trapline. Mink diet may be a factor in this variation. Local environmental levels of cadmium were not reflected in cadmium concentrations in mink tissues. Mercury, cadmium and selenium do not appear to constitute environmental hazards to mink in the Yukon.

    Brink, Anne-Line; Jeppesen, Leif Lau

    2005-01-01

    This study describes the development of the behaviour of mink kits and dams from the fourth to the eighth respectively seventh week after delivery. The study is based on scan observations of 72 mink dams and their kits at a conventional Danish mink farm. The kits started eating when they were about...... 30 d old. Drinking started almost 2 wk later. During these 2 wk there was a peak in the licking of saliva from the dam and of the inter-litter agonistic behaviour. A causal relationship between experienced thirst and agonistic behaviour is suggested. The kits' sucking declined to only 5% of the time...... budget in the seventh week and the stereotypy frequency of the dams increased to about 4% of the time budget. It is suggested that some dams are frustrated by the forced cohabitation with their nutritionally independent kits already in the seventh week and that this should be taken into account when...

    Adult Dioctophyma renale occupied the enlarged renal pelvis of the right kidney of naturally infected mink. Lesions in the kidney parenchyma consisted of connective tissue proliferation in the interstitial tissue, tubular atrophy and fibrosis, and periglomerular fibrosis. The luminal surface of the renal pelvis wall was formed of numerous papillae covered with transitional epithelium. The nematodes in the lumen were bathed in an albuminous fluid containing red blood cells, epithelial cells and D. renale eggs. The left (uninfected) kidney was 60% larger than the left kidney of normal mink.

    The mink is a strict carnivore and may therefore serve as a model for the cat. Current recommendations for protein supply for lactating mink are based on production experiments with preweaning kit growth as a measure of dietary adequacy (1,2). Recently, nitrogen balance and substrate oxidation have...... in humans (7), growing pigs (8), and growing rats (9). In adult cats, both protein synthesis and breakdown were lower when feeding a low- than when feeding a high-protein diet [20 vs. 70% of metabolizable energy (ME)5 from protein] (10). The objectives of this study were therefore to develop a ¹5N...

    2005-01-01

    The efficiency of utilization of milk amino acids for body gain in suckling mink kits from small (n = 3), medium (n = 6) and large litters (n = 9) was investigated by using 36 mink dams and their litters for measurements during lactation weeks 1 through 4. Measurements on each dam and litter were...... performed once, hence three dams per litter size each week (n = 9). Individual milk intake of kits was determined, milk samples were collected and kits were killed for determination of amino acid composition. The most abundant amino acids in milk were glutamate, leucine and aspartate making up about 40......% of total amino acids. Branched chained amino acids made up slightly more than 20% and sulphur containing amino acids less than 5% of total milk amino acids. In kit bodies the sum of glutamate, aspartate and leucine made up about 32% of amino acids, branched chain amino acids about 16% and sulphur...

    The present study aimed to examine if divergent selection for stereotypic behaviour in mink influences the welfare of the animals. Two breeding lines were used, a high stereotyping line (HSL, N = 139) and a low stereotyping line (LSL, N = 132). Their welfare was assessed on the basis...... of adrenocortical activity (faecal cortisol metabolites, FCM), confident versus fearful temperament, growth and reproduction. The results showed that the LSL performed less stereotypic behaviour and were less active than the HSL. Furthermore, the results demonstrated that: (1) the LSL had lower concentrations......) there was no failure to grow in any line, but on average the body weight in the LSL was higher than that in the HSL. The correlation between stereotypy and confidence in the present study supports earlier findings showing a higher proportion of fearful animals in groups of low stereotyping mink. So, although...

  10. Pulse of inflammatory proteins in the pregnant uterus of European polecats (Mustela putorius) leading to the time of implantation.

    Uterine secretory proteins protect the uterus and conceptuses against infection, facilitate implantation, control cellular damage resulting from implantation, and supply pre-implantation embryos with nutrients. Unlike in humans, the early conceptus of the European polecat ( Mustela putorius ; ferret) grows and develops free in the uterus until implanting at about 12 days after mating. We found that the proteins appearing in polecat uteri changed dramatically with time leading to implantation. Several of these proteins have also been found in pregnant uteri of other eutherian mammals. However, we found a combination of two increasingly abundant proteins that have not been recorded before in pre-placentation uteri. First, the broad-spectrum proteinase inhibitor α 2 -macroglobulin rose to dominate the protein profile by the time of implantation. Its functions may be to limit damage caused by the release of proteinases during implantation or infection, and to control other processes around sites of implantation. Second, lipocalin-1 (also known as tear lipocalin) also increased substantially in concentration. This protein has not previously been recorded as a uterine secretion in pregnancy in any species. If polecat lipocalin-1 has similar biological properties to that of humans, then it may have a combined function in antimicrobial protection and transporting or scavenging lipids. The changes in the uterine secretory protein repertoire of European polecats is therefore unusual, and may be representative of pre-placentation supportive uterine secretions in mustelids (otters, weasels, badgers, mink, wolverines) in general.

    Heart rate, arterial blood pressure and blood acid-base status were determined in 18 adult female mink (mean (+/- SEM) body weight 1052 +/- 34 g) during long-term anaesthesia with either controlled ventilation (n=12) or spontaneous respiration (n=6). Surgical anaesthesia was induced by intramuscular injection of ketamine hydrochloride (Ketaminol Vet, 40.0 +/- 1.7 mg/kg) and midazolam hydrochloride (Dormicum 2.8 +/- 0.1 mg/kg) and maintained for at least 5 h by continuous intravenous infusion of this drug combination in 0.9% saline. For all animals, the mean rates of infusion of ketamine and midazolam were 48.4 +/- 1.6 and 1.61 +/- 0.12 mg/h, respectively. Following continuous infusion of the anaesthetics in isotonic saline, at a rate of 20 ml/h, a moderate 'dilution acidosis' developed, which could be corrected by replacement of part of the saline with sodium bicarbonate to a final concentration of approximately 25 mmol NaHCO3 per litre. However, when the animals were allowed to breathe spontaneously, an increase in heart rate and a combined respiratory and metabolic acidosis occurred, due to severe respiratory depression. Apart from these effects and a few cases of increased salivation, no adverse effects over time were observed on the arterial blood acid-base status and cardiovascular function of the animals during ketamine/midazolam anaesthesia. It is concluded that the procedure described for long-term anaesthesia in mink is convenient and safe for acute physiological experiments in this species, provided normal body temperature and pulmonary gas exchange is sufficiently maintained. Thus, the need for an adequately controlled artificial ventilation is strongly emphasized. Finally, a proposal for the composition of an intravenous solution, containing ketamine and midazolam hydrochloride, and sodium bicarbonate in saline, suitable for long-term anaesthesia in adult mink is presented.

This demonstration of nutrient balancing in a carnivorous mammal indicates that the capacity for nutrient balancing is a more general phenomenon across trophic levels than was hitherto believed to be the case...

  13. The vomeronasal system of the mink, Mustela vison. I. The vomeronasal organ.

    Salazar, I; Cifuentes, J M; Quinteiro, P S; Caballero, G

    1994-01-01

    The vomeronasal organ (VNO) of the mink is restricted to the area of the Fissura palatina and thus always topographically related to the Ductus incisivus (DI). The VNO and DI have also a functional relation because the vomeronasal duct ends in the incisive duct. On the other hand, as the DI has its mouth in the Papilla incisiva there is a communication between the VNO and the oral cavity. The vomeronasal cartilage, approximately in 1/6 of its length, wraps completely the parenchyma of the VNO whose main structure is the vomeronasal duct, with two different epithelia: sensory receptor in the medial wall, and respiratory in the lateral one. Nevertheless the variations of epithelia belong to the segment of the duct because in its rostral and caudal parts the medial and lateral epithelia are very similar. Branches and tubular PAS positive glands stand out in three points: superior, inferior and medial areas of the vomeronasal duct in which they end. An important number of vessels, mainly veins of different diameter, are located around the duct, while the nervous fibers are close to the medial wall of the duct and very easy to identify in the caudal third of the organ. Two immunohistochemical techniques were used to identify the nerve fibers and the receptor cells.

    and after the experiments and evaporative water losses (EWL) were calculated. When exposed to L temperature, single kits responded with a very low HE until 29 days of age, and groups of kits until 14 days of age. It was not until they reached an age of approximately 6 weeks that single kits showed a clear...... thermoregulatory response to the L temperature by increased HE, whereas groups of kits showed increased HE from 29th day onwards. When kept at H temperature, HE was low initially, but all kits showed elevated HE at 8 days of age, and the metabolic rate was similar for single kits and kits huddling in groups....... Evaporative water losses was higher among single than among groups of kits and slightly lower but more variable for animals at L than at H temperature. It was concluded that mink kits develop functional homoeothermy at an age of close to 6 weeks and that the failure of very young kits to thermoregulate...

    Founding captive populations is often the last chance for saving endangered species from extinction. Ensuring successful reproduction is typically most critical for the maintenance of captive populations, with purposeful selection of individuals for breeding being one of the crucial aspects. Comparable cross-species data on the determinants of reproduction success are most useful for solving problems in captive species programs. In the present study, we provide an overview of a 20-year captive breeding program of the critically endangered European mink. The mating season starts in March, reaching its peak in the middle of April. The average gestation length was 43.8days (mode 43), the mean litter size being 4.4 (mode 4). Litter size and cub survival were negatively correlated with maternal age but this effect was entirely due to the lower performance of the females over 4 years of age. Female body weight also showed a positive correlation with litter size, with the weight itself having increased by 10% during the 20- year period. We did not find any signs of a cost of reproduction: the number of litters the female had delivered earlier in her life did not have an effect on her litter size in the focal year. Beyond the effect of age and size, individual females did not differ in litter sizes. Consistently, we found the heritability of litter size to be low. We conclude that, when selecting females for breeding, there is little need to consider aspects other than genetic relatedness crucial for avoiding progressive inbreeding.

Sixty-two female mink kept in standard cages and selected for high or low...... levels of stereotypy were used. Thirty of these females had access to a running wheel whereas thirty-two female mink had no access to running wheels. The number of turns of the running wheel, behaviour, feed consumption, body weight and the concentration of plasma cortisol were measured during the winter...... period. Mink with access to a running wheel did not perform stereotypic behaviour and mink selected for a high level of stereotypies had more turns in the running wheel than mink selected for low levels of stereotypies.

    Distemper virus causes a disease affecting minks with respiratory, gastrointestinal, neurological and skin symptoms and showing high morbidity and mortality, mainly among puppies. It is controlled through immunization, using vaccines that are supplied for mink use. The aim of this work was to determine the seroneutralization titer against the distemper virus at a mink farm in Argentina. The antibody kinetics obtained after vaccination in 27 adult animals, as well as the duration of colostrum-transferred antibodies in 10 puppies were determined. All vaccinated adult minks showed protective titers up to at least 3 months after vaccination, and 37.5% significantly reduced their antibody levels, 12 months after vaccination. Only 20% of the puppies showed protective levels of colostrum-transferred antibodies at the age of 7 weeks, while non-detectable levels of antibodies were found when puppies reached 11 weeks old. Vaccination performed in these puppies at the age of 13 weeks, elicited protective seroneutralization titers. These results show that vaccination induces a satisfactory humoral immune response in our environment, and support the convenience of vaccinating dams annually before the beginning of the breeding season. The vaccination plan in puppies is also discussed.

    1990-01-01

    Endogenous zinc excretion was studied in adult male mink fed experimental diets for 73 d, including a collection period from d 69 to 73. Dietary zinc levels were 2.8, 26 or 121 mg/kg wet weight. In accordance with the results of a methodological study, also reported here, the animals had an intramuscular injection of 65ZnCl2 12 d before the start of the collection period. Total fecal (endogenous + unabsorbed) zinc excretion for d 69-73 in the three groups was 2.3, 20.4 and 91.0 mg. The endogenous zinc excretion was 1.3, 2.0 and 6.4 mg, corresponding to 80.8, 10.6 and 6.4% of the zinc intake. Thus, the endogenous excretion was mainly important for the zinc homeostasis at low zinc intake, whereas at high intake the homeostasis was regulated via absorption from the digestive tract. The overall conclusion of the experiment was that mink are comparable to other species (including man) in regard to mechanisms controlling zinc homeostasis

La enfermedad se controla mediante la aplicación de vacunas destinadas a esta especie. El objetivo del trabajo fue determinar el título de anticuerpos neutralizantes contra el virus del distemper en visones vacunados y no vacunados de un criadero de Argentina. Se analizó la cinética de anticuerpos obtenidos posvacunación en 27 animales adultos y de anticuerpos calostrales en 10 cachorros. Todos los visones adultos vacunados mostraron títulos protectores hasta por lo menos 3 meses después de la vacunación. El 37,5% redujo significativamente sus niveles de anticuerpos a los 12 meses de la vacunación. En los cachorros, sólo un 20% mostró niveles protectores de anticuerpos calostrales a las 7 semanas de edad, que se negativizaron hacia las 11 semanas. La vacunación a las 13 semanas de edad produjo títulos protectores en todos estos animales. Estos resultados muestran que la vacunación induce respuesta humoral satisfactoria en el medio estudiado e indican la conveniencia de revacunar a las madres anualmente antes del servicio.

    Petroleum oil enters the coastal marine environment through various sources; marine mammals such as sea otters that inhabit this environment may be exposed to low concentrations of petroleum hydrocarbons through ingestion of contaminated prey. The inability to perform controlled studies in free-ranging animals hinders investigations of the effects of chronic petroleum oil exposure on sea otter morbidity and mortality, necessitating the development of a reliable laboratory model. We examined the effects of oral exposure to 500 ppm bunker C fuel oil over 113-118 days on American mink, a species phylogenetically related to the sea otter. Hematological parameters and organs were examined for fuel oil-associated changes. Hepatic cytochrome P4501A1 mRNA expression and fecal cortisol concentrations were also measured. Ingestion of fuel oil was associated with a decrease in erythrocyte count, hemoglobin concentration (Hgb), hematocrit (HCT), and an increase in mean corpuscular volume (MCV). Total leukocytes were elevated in the fuel oil group from increases in neutrophils, lymphocytes, and monocytes. Significant interactions between fuel oil and antigen challenge were found for erythrocyte parameters, monocyte and lymphocyte counts. Liver and adrenal weights were increased although mesenteric lymph node weights were decreased in the fuel oil group. Hepatic cytochrome P4501A1 mRNA was elevated in the fuel oil group. Fecal cortisol concentration did not vary between the two groups. Our findings show that fuel oil exposure alters circulating leukocyte numbers, erythrocyte homeostasis, hepatic metabolism and adrenal physiology and establish a framework to use mink as a model for sea otters in studying the systemic effects of marine contaminants

    As part of an ongoing effort to understand aryl hydrocarbon receptor (AhR) mediated toxicity in mink, cDNAs encoding for CYP1A1 and the CYP1A2 mixed function monooxygenases were cloned and characterized. In addition, the effects of selected dibenzofurans on the expression of these genes and the presence of their respective proteins (P4501A) were investigated, and then correlated with the catalytic activities of these proteins as measured by ethoxyresorufin O-deethylase (EROD) and methoxyresorufin O-deethylase (MROD) activities. The predicted protein sequences for CYP1A1 and CYP1A2 comprise 517 and 512 amino acid residues, respectively. The phylogenetic analysis of the mink CYP1As with protein sequences of other mammals revealed high sequence homology with sea otter, seals and the dog, with amino acid identities ranging from 89 to 95% for CYP1A1 and 81 to 93% for CYP1A2. Since exposure to both 2,3,7,8-Tetrachlorodibenzofuran (TCDF) and 2,3,4,7,8-Pentachlorodibenzofuran (PeCDF) resulted in dose-dependent increases of CYP1A1 mRNA, CYP1A2 mRNA and CYP1A protein levels an underlying AhR-mediated mechanism is suggested. The up-regulation of CYP1A mRNA in liver was more consistent to the sum adipose TEQ concentration than to the liver TEQ concentration in minks treated with TCDF or PeCDF. The result suggested that the hepatic-sequestered fraction of PeCDF was biologically inactive to the induction of CYP1A1 and CYP1A2

    In the early 2000’s, declines in the brown trout (Salmo trutta) fishery in Rapid Creek, South Dakota, caused concern for anglers and fisheries managers. We conducted a radio telemetry study in 2010 and 2011 to identify predation mortality associated with mink, using hatchery-reared (2010) or wild (2011) brown trout. Estimated predation rates by mink (Mustela vison) on radio-tagged brown trout were 30% for hatchery fish and 32% for wild fish. Size frequency analysis revealed that the size distribution of brown trout lost to predation was similar to that of other, radio-tagged brown trout. In both years, a higher proportion of predation mortality (83–92%) occurred during spring, consistent with seasonal fish consumption by mink. Predation by mink appeared to be a significant source of brown trout mortality in our study.

    Size sexual dimorphism was investigated on 695 skulls of four Mustelidae species. By extent of increasing of differences between sexes the species are placed in following order: European pine marten (Martes martes), European mink (Mustela lutreola), American mink (Neovison vison), and European polecat (Mustela putorius). Extent of the dimorphism characterizes ecological plasticity of the species and is population characteristic. It is shown that M. martes takes specific and relatively narrow ecological niche of forest ecosystems, entering into weak competitive relationships with smaller Mustelidae species. The level of sexual dimorphism of M. lutreola, N. vison and M. putorius reflects intensity of its interspecific relationships within study area. High level of sexual dimorphism of M. putorius is determined by further divergence of ecological niches of males and females, and also appears to be compensatory mechanism reducing consequences of hardened environmental requirements.

    We report two cases of asthma among mink workers. The first case is about a mink farmer who had asthma that was difficult to treat. In the medical history there was no clear relation to work, and no conclusive work relation with peak flow monitoring. He had a positive histamine release test to mink...... urine. The second case is about a mink farm worker, who had an asthma attack when handling mink furs. Peak flow monitoring showed a clear relation to this work, but there were no signs of allergy. We conclude that these two cases suggest an increased risk of asthma among mink workers....

    This paper describes a case of lead poisoning in minks. The mink were housed in pens which had been painted with a bridge paint containing lead. They had chewed on the pen and ingested the paint. The animals that did not die were moved to new pens, and vitamin D and calcium gluconate were added to their diets. In three days, a marked improvement was seen in the food and water consumption, and convolutions became less frequent.

  20. Alien Mink Predation and Colonisation Processes of Rodent Prey on Small Islands of the Baltic Sea: Does Prey Naivete Matter?

    International Nuclear Information System (INIS)

    Fey, K.; Korpimaki, E.; Banks, P.B.

    2010-01-01

    Colonisation, an important part of meta-population dynamics of fragmented populations, depends on both the dispersal ability and the ability to establish in the new habitat. Predation can hinder successful establishment of prey, and where the predation pressure comes from an alien predator, the effects on colonisation might be devastating. We studied the establishment of field voles (Microtus agrestis) inhabiting small islands of the archipelago of the Baltic Sea, SW Finland, under presence and absence of the alien American mink (Mustela vison). We translocated experienced voles from islands with mink, and inexperienced voles from islands from which mink had been removed, to other islands where mink was present or absent. By radio-tracking we studied survival, space and micro habitat use of voles within four weeks after translocation. Survival of voles on mink islands was significantly lower than on mink-free islands, but experienced voles did not survive better than inexperienced voles. Experienced voles were more often located in juniper habitats than inexperienced voles, but they appeared not to gain any survival benefit from altered micro habitat use. This study provides novel evidence, that alien mink predation inhibits establishment of colonising field voles and may thus ultimately induce extinction of voles from the outer archipelago.

  1. Water baths for farmed mink: intra-individual consistency and inter-individual variation in swimming behaviour, and effects on stereotyped behaviour

    Directory of Open Access Journals (Sweden)

    J. MONONEN

    2008-12-01

    Full Text Available Swimming behaviour and effects of water baths on stereotyped behaviour in farmed mink (Mustela vison were studied in three experiments. The singly-housed mink had access from their home cages to extra cages with 20.5 litre water baths. Two short-term experiments aimed to investigate how quickly adult and juvenile mink start using and how consistently they use water baths over 10 days, and whether the extent of the use correlates between dams and their females kits. A four-month experiment was designed to compare the development of stereotyped behaviour in juvenile mink housed with and without swimming opportunity. The behavioural analyses were based on several 24-hour video recordings carried out in all three experiments. There were obvious inter-individual differences and intra-individual consistency in swimming frequency and time. Farmed mink’s motivation to swim can be assessed in short-term experiments, and measurement of water losses from the swimming baths and use of instantaneous sampling with 10 min sampling intervals provide quite reliable measures of the amount of swimming. The bath use of the juveniles correlated with that of their dams, indicating that an individual mink’s eagerness to swim may have a genetic component. The lower amount of stereotyped behaviour in mink housed with water baths indicates that long-term access to baths may alleviate frustration in singly-housed juvenile farmed mink.;

    In this project, we test the hypothesis whether mink populations with a higher social tolerance have been developed in practice and thus are better adapted to housing in stacked cages. The hypothesis has been tested by comparing the level of bite damages and bit marks in mink kept in pairs...... and in mink kept in social groups. In total, the project included 1,191 brown mink housed on four farms in up to five different types of social groups. The result showed that mink in groups had significantly more bite marks than mink kept in pairs, and that mink with bite wounds had significantly more bite...... marks than mink that did not haev bite wounds. Thus, based upon bite mark results, we cannot confirm the hypothesis that mink populations adapted to group housing have been developed. The number of mink that had died or had been removede during the test period, or that had bite wounds at the time...

  4. Radiation pasteurization of mink feed

    1990-01-01

    No significant differences were observed in the net birth rate of mink kits/female between the 7 breeding groups. However, there was reduced incidence (P=0.05) of kit deaths among the females receiving irradiated feed, and larger kit size (P<0.0001) at birth particularly for the litter size of 5-8 kits. The second generation minks born to parents receiving feed irradiated to a planned dose of 1 kGy weighed on average about 2.5% more, and their fur was on average about 1±0.26 cm longer (12% more males making the top length grade). Moreover, there was no effect of irradiated feed on fur quality. Irradiation of mink feed with subsequent frozen storage of the meat component improved the microbiological quality by decreasing the incidence of Pseudomonas sp. and Salmonella sp. Radiation pasteurization of mink feed (frozen meat to 1 kGy, and dry feed to 2 kGy or more) should therefore help improve feed utilization, keep animals healthier, and reproducing better without affecting fur quality.

  7. Fatty acid alterations caused by PCBs (Aroclor 1242) and copper in adipose tissue around lymph nodes of mink

    International Nuclear Information System (INIS)

    Kaekelae, R.; Hyvaerinen, H.

    1999-01-01

    Fatty acid composition was determined in adipose tissue surrounding the mesenteric lymph nodes of mink (Mustela vison) exposed to polychlorinated biphenyls (PCBs: 1 mg Aroclor 1242 in food day -1 for 28 days) and/or copper (62 mg kg -1 food). These specific adipose tissues are known to have functional relationships with lymphocytes, and proliferation of cultured lymphocytes is influenced by the quality of fatty acids available in media. In six experimental groups the diet was based on freshwater fish, and in two groups it was based on marine fish. These basal diets differed in terms of fatty acid composition and content of fat-soluble vitamins A 1 and E. The fatty acid composition of membrane phospholipids (PL) responded to PCBs more than that of triacylglycerols (TG). The effects of copper were small. In female minks fed a diet of freshwater fish, the proportion of highly unsaturated fatty acids in PL decreased by 5 wt.% due to PCBs, and the acids seemed to be replaced by monounsaturated fatty acids (9 wt.% increase of total). This decrease of highly unsaturated fatty acids in PL was milder in minks on the marine fish diet rich in fat-soluble vitamins. In TG of minks on the marine diet, however, PCBs decreased the proportion of docosahexaenoic acid (22:6n-3). The possibility that these alterations in the fatty acid metabolism of adipose tissue supporting the lymph nodes affect immune function during PCB exposure should be studied further. Interestingly, the quality of the fish diet affected the magnitude of the alterations. The fatty acid responses may also differ between males and females.

    Aleutian mink disease virus (AMDV) causes severe disease in farmed mink (Neovison vison) worldwide. In Denmark, AMDV in farmed mink has been confined to the northern part of the mainland since 2002. From 1998 to 2009, samples from 396 free-ranging mink were collected from mainland Denmark......, and a low AMDV antibody prevalence (3% of 296) was found using countercurrent immune electrophoresis. However, on the island of Bornholm in the Baltic Sea, a high prevalence (45% of 142 mink) was detected in the free-ranging mink. Aleutian mink disease virus was detected by polymerase chain reaction in 32...... of 49 antibody-positive free-ranging mink on Bornholm, but not in mink collected from other parts of Denmark.

    Abstract There are few reports describing the structure and function of the whale placenta with the advance of pregnancy. In this study, therefore, the placenta and nonpregnant uterus of the Antarctic minke whale were observed morphologically and immunohistochemically. Placentas and nonpregnant uteri were collected from the 15th, 16th and 18th Japanese Whale Research Programme with Special Permit in the Antarctic (JARPA) and 1st JARPA II organized by the Institute of Cetacean Research in Tokyo, Japan. In the macro- and microscopic observations, the placenta of the Antarctic minke whale was a diffuse and epitheliochorial placenta. The chorion was interdigitated to the endometrium by primary, secondary and tertiary villi, which contained no specialized trophoblast cells such as binucleate cells, and the interdigitation became complicated with the progress of gestation. Furthermore, fetal and maternal blood vessels indented deeply into the trophoblast cells and endometrial epithelium respectively with fetal growth. The minke whale placenta showed a fold-like shape as opposed to a finger-like shape. In both nonpregnant and pregnant uteri, many uterine glands were distributed. The uterine glands in the superficial layer of the pregnant endometrium had a wide lumen and large epithelial cells as compared with those in the deep layer. On the other hand, in the nonpregnant endometrium, the uterine glands had a narrower lumen and smaller epithelial cells than in the pregnant endometrium. In immunohistochemical detection, immunoreactivity for P450scc was detected in most trophoblast cells, but not in nonpregnant uteri, suggesting that trophoblast epithelial cells synthesized and secreted the sex steroid hormones and/or their precursors to maintain the pregnancy in the Antarctic minke whale.

    2003-01-01

    The effects of a 21-week exposure to Aroclor 1242 (1 mg per day in feed on plasma concentrations of vitamins A 1 (retinol) and A(3,4-didehydroretinol) and their principal fatty acyl esters (A 1 -16:0 A 2 -16:0 (palmitates), A 1 -18:1n-9; A 2 -18:1n-9 (oleates), and A 1 -18:0 A 2 -18:0 (stearates)) were studied in young female mink (Mustela vison) fed a diet based on freshwater smelt. These vitamin levels were also examined in mink fed diets containing Baltic herring or fatty marine fish. In the Aroclor-exposed smelt-fed mink, the plasma concentrations of A 1 and Aesters were significantly lower than the levels in controls fed the uncontaminated smelt diet. In addition, the A 2 esters reacted mor sensitively to the polychlorinated biphenyls than did A 1 esters. I contrast, in the plasma of the exposed mink the level of alcoholic A 1 was normal, and transport of thyroxine (T 4 ) and nonspecific lipoprotei transport of major lipids were not impaired. Despite the large dietary supply of vitamin A 2 and high levels of plasma A 2 esters, the mink fed freshwate smelt had only trace amounts of alcoholic vitamin A 2 in their plasma. The concentrations of A 1 and A 2 esters in the plasma of all the mink studied correlated with the hepatic total concentrations of the vitamins. Thus, in carnivores that have nonspecific lipoprotein transport of vitamin A esters determination of plasma levels of the esterified vitamins may be a useful nondestructive way to estimate stores of the vitamin A analogs in the body and to assess the organochlorine-induced decrease in the vitamin stores

    A rare color variant of the American mink (Neovison vison), discovered on a ranch in Nova Scotia and referred to as the "marbled" variety, carries a distinctive pigment distribution pattern resembling that found in some other species, e.g., the Siamese cat and the Himalayan mouse. We tested...... the hypothesis that the color pattern in question-light-colored body with dark-colored points (ears, face, tail, and feet)-is due to a mutation in the melanin-producing enzyme tyrosinase (TYR) that results in temperature-sensitive pigment production. Our study shows that marbled mink carry a mutation in exon 4...... of the TYR gene (c.1835C > G) which results in an amino acid substitution (p.H420Q). The location of this substitution corresponds to the amino acid position that is also mutated in the TYR protein of the Himalayan mouse. Thus, the marbled variant is more aptly referred to as the Himalayan mink....

    1999-01-01

    A 2-year-old Siberian polecat (Mustela eversmanni) from a breeding colony presented for ultrasound evaluation for pregnancy. It was paired with a male for 2.75 months and had remained absent of pregnancy signs when it was anesthetized and clinically evaluated. Until this time, the animal had eaten well and shown no outward signs of debility. On palpation, the animal had a fluid-filled tubular structure in the caudal abdomen, consistent in location and size with the uterus. No sign of vaginal discharge was present. Ultrasonography revealed 10 fluid-filled evaginations (approximately 12 mm in diameter) of the uterine horns. A presumptive diagnosis of a fluid-filled reproductive tract and likely reproductive failure was made in light of the animal's history, its clinical signs, and the ultrasound findings. Euthanasia was performed because the animal was nonreproductive and might yield information relevant to the breeding colony as a whole. Necropsy of the polecat revealed a distended fluctuant uterus containing mildly odiferous, thick, yellow-green, purulent material. Histopathology confirmed the diagnosis of pyometra. A pure and heavy growth of Enterococcus fecalis was cultured from the uterine contents. In light of results from routine minimal inhibitory concentration antibiotic sensitivity screening, this isolate was resistant to all antibiotics tested in the standard teaching hospital screen.

Ultrasonography revealed 10 fluid-filled evaginations (approximately 12 mm in diameter) of the uterine horns. A presumptive diagnosis of a fluid-filled reproductive tract and likely reproductive failure was made in light of the animal's history, its clinical signs, and the ultrasound findings. Euthanasia was performed because the animal was nonreproductive and might yield information relevant to the breeding colony as a whole. Necropsy of the polecat revealed a distended fluctuant uterus containing mildly odiferous, thick, yellow-green, purulent material. Histopathology confirmed the diagnosis of pyometra. A pure and heavy growth of Enterococcus fecalis was cultured from the uterine contents. In light of results from routine minimal inhibitory concentration antibiotic sensitivity screening, this isolate was resistant to all antibiotics tested in the standard teaching hospital screen.

    Full Text Available The objective of this study was to determine whether nutrient digestibility and reproductive performance of pregnant mink (Neovison vison were affected by different dietary protein levels. One hundred and twenty female mink were randomly assigned to four groups, receiving diets of fresh material with different protein levels. The dietary protein levels, expressed as percentage of dry matter (DM, were 32, 36, 40 and 44% respectively. These values corresponded to average 320, 360, 400 and 440 g protein/kg DM, respectively. Results were as follows. All of crude protein digestibility, nitrogen (N intake, N retention increased along with dietary protein level increasing. Low protein level (32% significantly reduced the above indicators (P < 0.05. DM digestibility and ether extract digestibility were not affected by dietary protein level. Results of mated females, barren females, kids per litter, live born kids per mated female, birth survival rate, and birth weight showed that mink achieved optimal reproductive performance when dietary protein level was 36%. In conclusion, dietary protein was anticipated to significantly influence some nutrients' utilization. Adopting the appropriate dietary protein level allow better reproduction performance. The most preferable reproductive performance was achieved when diet contained 275.5 g digestible protein per kg DM for female mink in gestation.

    The emerging skin disease fur animal epidemic necrotic pyoderma (FENP) has been attributed to infection with Arcanobacterium phocae (ABP). The exact pathogenesis and risk factors of FENP have yet to be elucidated. Three mink from each of three different mink farms (A-C) with postvaccination skin wounds at the vaccination site and six mink from an unaffected mink farm (D) that had used the same vaccine batch and vaccination site (hind leg). All mink from farms A-C had severe necrotizing to necropurulent dermatitis where they were vaccinated intramuscularly in the hind leg. ABP was the sole bacterium cultured from six of nine wounds. Using 16S-23S rDNA intergenic spacer region and BOX-PCR, the ABP isolates from these wounds were indistinguishable from isolates originating from several cases of FENP. This is the first report of FENP-like lesions at the site of vaccination, in the days following the procedure, associated with ABP. At farms with FENP vaccination, procedures should be considered carefully. © 2016 ESVD and ACVD.

    The effect of Helicobacter mustelae infection on gastric epithelial proliferation was studied in ferrets colonized with H.mustelae and specific pathogen-free (SPF) ferrets not infected with H.mustelae. Thirteen H. mustelae-infected ferrets between the ages of 13 and 32 months and 16 SPF ferrets between 6 and 18 months were analyzed. Bacterial cultures, urease tests and Warthin-Starry stains were used to identify H.mustelae. Tissues obtained from the antrum and the body regions of the stomach were assayed by proliferating cell nuclear antigen (PCNA) immunohistochemistry and measured using a computerized color image analysis system. PCNA-expressing gastric epithelia in the antrum and the body regions were significantly increased in the H.mustelae-infected ferrets versus the SPF ferrets (P < 0.001). PCNA positivity in the antrum regions of both the H.mustelae-infected ferrets and SPF ferrets was significantly higher than that of the body regions (P < 0.001). Comparison of the histopathology of infected ferrets indicated that PCNA positivity correlated with the histological severity of gastritis. This study suggests that cell proliferation in ferret gastric mucosa increases with H.mustelae infection and provides evidence that PCNA is a useful biomarker for studying the changes in cell kinetics in the ferret stomach. The data also further support the use of the H.mustelae-infected ferret as an animal model for studying the pathogenesis of Helicobacter pylori-induced gastric diseases of humans.

    Abstract Background Helicobacter mustelae causes gastritis, ulcers and gastric cancer in ferrets and other mustelids. H. mustelae remains the only helicobacter other than H. pylori that causes gastric ulceration and cancer in its natural host. To improve understanding of H. mustelae pathogenesis, and the ulcerogenic and carcinogenic potential of helicobacters in general, we sequenced the H. mustelae genome, and identified 425 expressed proteins in the envelope and cytosolic proteome. Results The H. mustelae genome lacks orthologs of major H. pylori virulence factors including CagA, VacA, BabA, SabA and OipA. However, it encodes ten autotransporter surface proteins, seven of which were detected in the expressed proteome, and which, except for the Hsr protein, are of unknown function. There are 26 putative outer membrane proteins in H. mustelae, some of which are most similar to the Hof proteins of H. pylori. Although homologs of putative virulence determinants of H. pylori (NapA, plasminogen adhesin, collagenase) and Campylobacter jejuni (CiaB, Peb4a) are present in the H. mustelae genome, it also includes a distinct complement of virulence-related genes including a haemagglutinin\\/haemolysin protein, and a glycosyl transferase for producing blood group A\\/B on its lipopolysaccharide. The most highly expressed 264 proteins in the cytosolic proteome included many corresponding proteins from H. pylori, but the rank profile in H. mustelae was distinctive. Of 27 genes shown to be essential for H. pylori colonization of the gerbil, all but three had orthologs in H. mustelae, identifying a shared set of core proteins for gastric persistence. Conclusions The determination of the genome sequence and expressed proteome of the ulcerogenic species H mustelae provides a comparative model for H. pylori to investigate bacterial gastric carcinogenesis in mammals, and to suggest ways whereby cag minus H. pylori strains might cause ulceration and cancer. The genome sequence was

    High-quality sequencing of the dog (Canis lupus familiaris) genome has enabled enormous progress in genetic mapping of canine phenotypic variation. The red fox (Vulpes vulpes), another canid species, also exhibits a wide range of variation in coat color, morphology, and behavior. Although the fox genome has not yet been sequenced, canine genomic resources have been used to construct a meiotic linkage map of the red fox genome and begin genetic mapping in foxes. However, a more detailed gene-specific comparative map between the dog and fox genomes is required to establish gene order within homologous regions of dog and fox chromosomes and to refine breakpoints between homologous chromosomes of the 2 species. In the current study, we tested whether canine-derived gene-containing bacterial artificial chromosome (BAC) clones can be routinely used to build a gene-specific map of the red fox genome. Forty canine BAC clones were mapped to the red fox genome by fluorescence in situ hybridization (FISH). Each clone was uniquely assigned to a single fox chromosome, and the locations of 38 clones agreed with cytogenetic predictions. These results clearly demonstrate the utility of FISH mapping for construction of a whole-genome gene-specific map of the red fox. The further possibility of using canine BAC clones to map genes in the American mink (Mustela vison) genome was also explored. Much lower success was obtained for this more distantly related farm-bred species, although a few BAC clones were mapped to the predicted chromosomal locations.

    In mid-August 2013, two H9N2 influenza viruses, named A/mink/Shandong/F6/2013 (Mk/SD/F6/13) and A/mink/Shandong/F10/2013 (Mk/SD/F10/13), were isolated from lung samples of 2 of 45 farmed mink exhibiting respiratory signs in mideastern Shandong province, China. The seroprevalence of antibodies to H9N2 in mink was 20% (53/265). Based on sequence analysis, the eight nucleotide sequences showed 99.7-100% identity between Mk/SD/F6/13 and Mk/SD/F10/13. The HA, NP and NS genes of Mk/SD/F6/13 and Mk/SD/F10/13 were close to A/chicken/Zhejiang/329/2011 (H9N2), the NA and PB1 genes to A/duck/Hunan/S4111/2011 (H9N2), the PA and M genes to A/chicken/Shanghai/C1/2012 (H9N2). However, the PB2 genes had a close relationship with A/Turkey/California/189/66 (H9N2). Based on Sialic acid (SA) receptor detection, a range tissues of the mink demonstrated staining for MAA and/or SNA, and mink could serve as an intermediate host for influenza viruses with pandemic potential for the other animals. Experimental infection of mink demonstrated that mink could be infected by H9N2 influenza viruses and presented mild clinical signs, virus shedding and seroconversion, but no animals died of the disease. It implied that mammalian host-adapted avian H9N2 strains infected mink. Copyright © 2015 Elsevier B.V. All rights reserved.

    Full Text Available The mink is a strict carnivore and a seasonal breeder, which may be used as an experimental model for other carnivores. Using anatomical methods, 32 brains of the N. American mink were examined. It was found that the brain consists of four ventricles. Also, it was noted that the posterior horn was missing and that the olfactory recess was present in the lateral ventricle, a large-size interthalamic connection was present in the third ventricle, and a flat, necklace like bottom in the fourth ventricle. Only recently, the ins and outs of the mink’s anatomical structure have begun to absorb the attention of anatomists. Apparently, it is related to the fact that fury animals, among them the mink, are being domesticated. For this reason and because of easy access to the material, the purpose of brain dissection is to familiarize with the three dimensional structure of the brain and teach one of the great methods of studying the brain: looking at its structure.

    Aleutian disease (AD) of mink most closely resembles systemic lupus erythematosus (SLE) in man; both are immune complex disease. In experimental AD serum immune complexes are determined by the 125 J-C 1 q-binding test using human C 1 q. Mink (n = 12) infected intraperitoneally with Aleutian disease virus (ADV), grown in fetal mink kidney cells, developed during the course of infection a mean of 125 I-C 1 q serum binding equivalent to 3.62 +- 1.68 mg./ml. aggr. HGG. (aggregated human immunoglobulin). Sera of mink (n = 8) which were infected with ADV grown in L-cells showed a less marked 125 I-C 1 q binding with a mean equivalent to 2.52 +- 1.43 mg./ml. aggr. HGG. In contrast control animals (n = 8) treated with non-ADV-infected mink epidermal fibroblasts or Eagle's minimal essential medium substituted with fetal calf serum only bound 125 I-C 1 q equivalent to 1.02 +- 0.99 mg./ml. aggr. HGG. In mink infected with ADV propagated in fetal mink kidney cells a constant increase in the 125 I-C 1 q serum binding occurred from the 4th to the 7th and 13th week after ADV infection. Mink which were infected with ADV propagated in mouse L-cells exhibited a different pattern of the 125 I-C 1 q serum binding capacity with a sharp increase from the 4th to the 7th week, followed by a decline towards the 13th week post infection. The serum 125 I-C 1 q binding capacity of all experimental animal groups exhibited at different times of the experiment a significant correlation with the presence of hypergammaglobulinaemia and raised ADV-antibody titers. From the data obtained it appears that the 125 I-C 1 q binding test, utilizing human C 1 q, is a suitable method for the detection of circulating serum immune complexes in mink during the course of ADV-infection.

    The purpose of this study was to determine whether oral immunization of ferret kits with a whole-cell sonicate of Helicobacter mustelae lysate (Hml) and the adjuvant muramyl dipeptide (MDP) would reduce the incidence of natural colonization with H. mustelae and the extent of Helicobacter-associated gastritis by enhancing the host mucosal immune response. Between the ages of 4 and 11 weeks, 44 ferret kits were gavaged with Hml and various doses of MDP. The extent of gastritis and duodenitis and the immune response to H. mustelae were evaluated. All kits became colonized naturally with H. mustelae and the majority developed mild to severe gastritis and duodenitis. Kits that received Hml with MDP developed significantly greater inflammation of the gastric antrum and duodenum, as compared to kits vaccinated with Hml alone. Vaccination with Hml and 50 micrograms of MDP was associated with severe lesions in the proximal duodenum characterized by accumulation of mononuclear inflammatory cells, mucosal erosion, and ulceration. Although serum antibody specific for H. mustelae in 4-week-old kits was approximately 50% of adult levels, a finding attributable to passively acquired maternal antibody, both systemic and mucosal antibody levels became depressed over time despite oral vaccination. The humoral immune response was sufficiently low to prevent detection of any significant dose effect of MDP on antibody levels among experimental groups. Oral vaccination of young ferrets with Hml and 50 micrograms MDP increased the risk of Helicobacter-associated mucosal ulceration in the proximal duodenum, which was associated with low humoral (but significant cell-mediated) immune responses to H. mustelae. In retrospect, the frequency of vaccination may have suppressed the systemic humoral immune response, thereby promoting mucosal damage by H. mustelae. The 50-microgram dose of MDP enhanced the cell-mediated immune response, which indirectly contributed to development of severe lesions

    Recrudescence or reinfection may occur after eradication of Helicobacter pylori in humans. We used the ferret Helicobacter mustelae model to investigate the effect of prior infection and eradication on reinfection by experimental and natural routes. Two groups of ferrets with naturally acquired H. mustelae infection were treated with an eradication protocol using amoxicillin, metronidazole, and bismuth subsalicylate. The ferrets were monitored for recrudescence by repeated cultures of endoscopic gastric mucosal biopsies. The ferrets were challenged at 17 months (group I) and 6 months (group II) after eradication with a strain of H. mustelae having a distinctive restriction endonuclease analysis pattern. The eradication protocol was repeated to eliminate the infection produced by experimental challenge. The ferrets were then cohoused intermittently with naturally infected ferrets. The original H. mustelae infection was successfully eliminated by the eradication protocol. No recrudescence was observed in group I for 12 months nor for 3 months in group II after eradication. All ferrets became persistently reinfected with the challenge strain. The infection from the challenge strain was eradicated successfully. No ferrets in group I and all ferrets in group II became infected through cohousing. These results suggest that though prior infection with H. mustelae may confer some protection against reinfection, such protection is not universal in all circumstances; that susceptibility to reinfection by contact with infected animals varies between individuals; and that age may be a factor in this individual variability. These results are applicable to studies of reinfection after eradication of H. pylori in humans.

    Control and eradication of Aleutian Mink Disease Virus (AMDV) are a major concern for fur-bearing animal production. Despite notably reducing disease prevalence, current control programs are unable to prevent the reinfection of farms, and environmental AMDV persistence seems to play a major role regarding this issue. In this study 114 samples from different areas and elements of seven infected mink farms were analyzed by qPCR in order to evaluate the environmental distribution of AMDV load. Samples were classified into nine categories, depending on the type of sample and degree of proximity to the animals, the main source of infection. Two different commercial DNA extraction kits were employed in parallel for all samples. qPCR analysis showed 69.3% positive samples with one kit and 81.6% with the other, and significant differences between the two DNA extraction methods were found regarding AMDV DNA recovery. Regarding sample categorization, all categories showed a high percentage of AMDV positive samples (31%-100%). Quantification of positive samples showed a decrease in AMDV load from animal barns to the periphery of the farm. In addition, those elements in direct contact with animals, the street clothes and vehicles of farm workers and personal protective equipment used for sampling showed a high viral load, and statistical analysis revealed significant differences in AMDV load between the first and last categories. These results indicate high environmental contamination of positive farms, which is helpful for future considerations about cleaning and disinfection procedures and biosecurity protocols.

    Toxaphene contamination of minke whales (Balaenoptera acutorostrata) from North Atlantic waters was examined for the first time. Total toxaphene and {sigma}CHB (sum of 11 chlorobornanes) concentrations in blubber samples ranged from 170 {+-} 110 and 41 {+-} 39 ng/g lipid weight (l.w.) for female minke whales from southeastern Greenland to 5800 {+-} 4100 and 1100 {+-} 780 ng/g l.w. for males from the North Sea, respectively. Very large variations in toxaphene concentrations among sampling areas were observed suggesting a spatial segregation of minke whales. However, much of the apparent geographical discrimination was explained by the seasonal fluctuation of animal fat mass.

    No significant differences were observed in the net birth rate of mink kits/female between the 7 breeding groups. However, there was reduced incidence (P=0.05) of kit deaths among the females receiving irradiated feed, and larger kit size (P<0.0001) at birth particularly for the litter size of 5-8 kits. The second generation minks born to parents receiving feed irradiated to a planned dose of 1 kGy weighed on average about 2.5% more, and their fur was on average about 1{plus minus}0.26 cm longer (12% more males making the top length grade). Moreover, there was no effect of irradiated feed on fur quality. Irradiation of mink feed with subsequent frozen storage of the meat component improved the microbiological quality by decreasing the incidence of Pseudomonas sp. and Salmonella sp. Radiation pasteurization of mink feed (frozen meat to 1 kGy, and dry feed to 2 kGy or more) should therefore help improve feed utilization, keep animals healthier, and reproducing better without affecting fur quality.

    Single or multiple semispherical to bilobulated fluid-filled cystic structures of variable size were observed on the dorsal aspects of the urinary bladder of four male and two female ferrets (Mustela putorius furo). All ferrets had been neutered. On physical examination, the cysts were palpated as caudal abdominal masses. Three of the six ferrets presented with dysuria, and two ferrets had signs compatible with endocrine dysfunction. Adrenal cortical hyperplasia or neoplasia were observed in all of the five ferrets examined. Sex hormones assayed in one of the six ferrets revealed elevated levels of serum estrodiol. The posterior aspect of the cysts was located on and/or attached to the trigone or neck of the bladder, with variable intraluminal communication with the bladder and/or the urethra. The anterior aspect of the cysts projected dorsally or dorsocranially into the caudal abdomen. The cysts were thin walled and contained urinelike fluid (n = 5) or viscous yellow fluid (n = 1). Histologically, the cyst walls were composed of three layers, epithelium, muscle, and serosa, with fibrovascular stroma between layers. The epithelium consisted of simple to stratified transitional, columnar, or squamous epithelial cells. The muscular layer consisted of intermittent bundles and/or single to double layers of continuous to discontinuous smooth muscle. The serosal layer consisted of loose fibrous stroma covered by flattened mesothelial cells. The cystic anomalies in these ferrets were most likely derived from the urogenital glands/ducts or other remnants.

    The genomes of canine parvovirus and mink enteritis virus were compared by restriction enzyme analysis of their replicative-form DNAs. Of 79 mapped sites, 68, or 86%, were found to be common for both types of DNA, indicating that canine parvovirus and mink enteritis virus are closely related viruses. Whether they evolved from a common precursor or whether canine parvovirus is derived from mink enteritis virus, however, cannot be deduced from our present data.

  20. Environmental enrichment reduces signs of boredom in caged mink.

    Directory of Open Access Journals (Sweden)

    Rebecca K Meagher

    Full Text Available Animals housed in impoverished cages are often labelled 'bored'. They have also been called 'apathetic' or 'depressed', particularly when profoundly inactive. However, these terms are rarely operationally defined and validated. As a negative state caused by under-stimulation, boredom should increase interest in stimuli of all kinds. Apathy (lack of interest, by contrast, should manifest as decreased interest in all stimuli, while anhedonia (loss of pleasure, a depressive symptom should specifically decrease interest in normally rewarding stimuli. We tested the hypotheses that mink, a model carnivore, experience more boredom, depression-like apathy, or anhedonia in non-enriched (NE cages than in complex, enriched (E cages. We exposed 29 subjects (13 E, 16 NE to ten stimuli categorized a priori as aversive (e.g. air puffs, rewarding (e.g. evoking chasing or ambiguous/neutral (e.g. candles. Interest in stimuli was assessed via latencies to contact, contact durations, and durations oriented to stimuli. NE mink contacted all stimuli faster (P = 0.003 than E mink, and spent longer oriented to/in contact with them, albeit only significantly so for ambiguous ones (treatment*type P<0.013. With stimulus category removed from statistical models, interest in all stimuli was consistently higher among NE mink (P<0.0001 for all measures. NE mink also consumed more food rewards (P = 0.037. Finally, we investigated whether lying down while awake and stereotypic behaviour (both increased by NE housing predicted these responses. Lying awake positively co-varied with certain measures of increased exploration. In contrast, stereotypic 'scrabbling' or locomotion (e.g. pacing did not. Overall, NE mink showed no evidence of apathy or depression, but instead a heightened investigation of diverse stimuli consistent with boredom. This state was potentially indicated by spending much time lying still but awake (although this result requires replication. Boredom can

    Major histocompatibility complex (MHC) genes encode proteins that play a critical role in vertebrate immune system and are highly polymorphic. To further understand the molecular evolution of the MHC genes, we compared MHC class II DRB genes between the Japanese weasel (Mustela itatsi), a species endemic to Japan, and the Siberian weasel (Mustela sibirica), a closely related species on the continent. We sequenced a 242-bp region of DRB exon 2, which encodes antigen-binding sites (ABS), and found 24 alleles from 31 M. itatsi individuals and 17 alleles from 21 M. sibirica individuals, including broadly distributed, species-specific and/or geographically restricted alleles. Our results suggest that pathogen-driven balancing selection have acted to maintain the diversity in the DRB genes. For predicted ABS, nonsynonymous substitutions exceeded synonymous substitutions, also indicating positive selection, which was not seen at non-ABS. In a Bayesian phylogenetic tree, two M. sibirica DRB alleles were basal to the rest of the sequences from mustelid species and may represent ancestral alleles. Trans-species polymorphism was evident between many mustelid DRB alleles, especially between M. itatsi and M. sibirica. These two Mustela species divided about 1.7 million years ago, but still share many MHC alleles, indicative of their close phylogenetic relationship. © 2015 John Wiley & Sons A/S.

    A 6 yr old female spayed large Munsterlander was evaluated following a 3 wk history of lethargy, inappetence, intermittent fever, and a recent change to the timing of her previously diagnosed heart murmur. Physical examination revealed marked dehydration, lethargy, and a grade 5/6 to-and-fro heart murmur that was auscultated best at the right sternal border. The dog was febrile, and echocardiography revealed a large, mobile, vegetative lesion in the right ventricular outflow tract associated with a ventricular septal defect (VSD). Mild aortic insufficiency was present. Corynebacterium mustelae (C. mustelae) was isolated from a pooled blood culture. Treatment of infective endocarditis (IE) was initiated along with supportive care, and the patient was discharged 9 days later. The dog remained without clinical signs 132 days after discharge. VSD is rarely mentioned as a predisposing factor for development of IE in veterinary literature; however, this report highlights that dogs with a VSD may be at risk for IE. To the authors' knowledge, this is the first documented case of a canine infection with C. mustelae. Infection with C. mustelae in this case represents a novel agent for IE in the dog.

    Full Text Available Introduction: The aim of the study was to investigate the mechanical and geometric properties as well as bone tissue and mineral density of long bones in mink dams exposed to deoxynivalenol (DON since one day after mating, throughout gestation (ca. 46 d and lactation to pelt harvesting. Material and Methods: Thirty clinically healthy multiparous minks (Neovison vison of the standard dark brown type were used. After the mating, the minks were randomly assigned into two equal groups: nontreated control group and DON group fed wheat contaminated naturally with DON at a concentration of 1.1 mg·kg-1 of feed. Results: The final body weight and weight and length of the femur did not differ between the groups. However, DON contamination decreased mechanical endurance of the femur. Furthermore, DON reduced the mean relative wall thickness and vertical wall thickness of the femur, while vertical cortical index, midshaft volume, and cross-sectional moment of inertia increased. Finally, DON contamination did not alter bone tissue density, bone mineral density, or bone mineral content, but decreased the values of all investigated structural and material properties. Conclusion: DON at applied concentration probably intensified the process of endosteal resorption, which was the main reason for bone wall thinning and the weakening of the whole bone.

    Cestode larvae spend one phase of their two-phase life cycle in the viscera of rodents, but cases of cestodes infecting subterranean rodents have only been rarely observed. To experimentally gain some insight into this phenomenon, we captured approximately 300 plateau zokors (Eospalax baileyi), a typical subterranean rodent inhabiting the Qinghai-Tibet Plateau, and examined their livers for the presence of cysts. Totally, we collected five cysts, and using a mitochondrial gene (cox1) and two nuclear genes (pepck and pold) as genetic markers, we were able to analyze the taxonomy of the cysts. Both the maximum likelihood and Bayesian methods showed that the cysts share a monophyly with Taenia mustelae, while Kimura 2-parameter distances and number of different sites between our sequences and T. mustelae were far less than those found between the examined sequences and other Taeniidae species. These results, alongside supporting paraffin section histology, imply that the cysts found in plateau zokors can be regarded as larvae of T. mustelae, illustrating that zokors are a newly discovered intermediate host record of this parasite.

    The American mink (Neovison vison) is a mustelid native to North America that was introduced in Europe and the former USSR for fur farming. Throughout the last century, accidental or deliberate escapes of mink from farms caused the establishment of stable feral populations. In fact, the American mink is considered an invasive alien species in 28 European countries. The present study evaluates the gastrointestinal and cardiopulmonary helminth fauna of the American mink in Galicia (NW Spain) to understand its role as a potential reservoir for parasites affecting other autochthonous mustelids. In the period 2008-2014, fifty American mink (35 males and 15 females) of different ages (22 immature and 28 adults) from the provinces of Lugo, Ourense and Pontevedra were captured and sacrificed. Eight parasite species were found (6 nematodes and 2 trematodes) with the following prevalences: Molineus patens (68%), Aonchotheca putorii (54%), Crenosoma melesi (10%), Aonchotheca annulosa (8%), Angiostrongylus daskalovi (6%), Aelurostrongylus spp. (2%), Troglotrema acutum (2%) and an unidentified trematode (2%). Eighty-two per cent of the mink harboured helminths, including 15 animals (30%) infected by only one parasite species, 19 (38%) by two species, 5 (10%) by three species and 2 mink (4%) by four species. All helminth species identified are native to European mustelids. Statistical models were used to evaluate if animal characteristics (age, sex and weight), date and capture area influenced the prevalence, intensity or parasite richness. Statistical differences were detected only in models for intensity of M. patens, A. putorii and C. melesi. This is the first report of Angiostrongylus daskalovi, a cardiopulmonary nematode, and A. annulosa, a gastrointestinal nematode specific of rodents, in American mink. Moreover, although the fluke T. acutum has already been cited in American mink, to our knowledge, the present study represents the first report of this trematode in the

    Mink are an important animal commodity group in Canada and excessive kit mortality represents a significant loss to production. National biosecurity standards have been developed for Canadian mink farms, but it is unclear how well these standards have been implemented as there are no studies correlating management practices of mink producers with causes of death in mink kits. To that end, we surveyed Ontario mink producers on their biosecurity and management practices and conducted almost 5660 post mortem examinations on found-dead, preweaned kits to characterize mink farm biosecurity practices and causes of death in preweaned kits. We found that very few biosecurity and management practices were uniformly used by producers, despite good awareness of appropriate practices. Use of personal protective equipment was implemented by fewer than 50% of respondents, while control of mink shed access, disinfection of feed containers after use, and use of a rodent control program were the only practices implemented by greater than 70% of respondents. Only 18% of producers reported regular use of antimicrobials in feed or water, although 91% stated they used antimicrobials for treatment of bacterial diseases on a regular basis. On post mortem examination, no gross abnormalities were noted in 71% of the kits, 45% were thought to be stillborn or aborted, 27% had some form of abnormal fluid distribution in the body, and 2% had a congenital malformation. A subset of 69 gastrointestinal tract samples was submitted for bacterial culture, of which 45 samples yielded sufficient growth. Most interesting was the identification of Salmonella enterica serovar Heidelberg in 11% of samples. The results of this study will provide a benchmark for Canadian mink producers and their veterinarians, defining the areas to which greater attention should be given to ensure more rigorous biosecurity practices are in place. Ultimately, these improvements in practices may contribute to increased mink

    Full Text Available A comparative study between aerial cue–counting and digital photography surveys for minke whales conducted in Faxaflói Bay in September 2003 is used to check the perpendicular distances estimated by the cue-counting observers. The study involved 2 aircraft with the photo plane at 1,700 feet flying above the cue–counting plane at 750 feet. The observer–based distance estimates were calculated from head angles estimated by angle-boards and declination angles estimated by declinometers. These distances were checked against image–based estimates of the perpendicular distance to the same whale. The 2 independent distance estimates were obtained for 21 sightings of minke whale, and there was a good agreement between the 2 types of estimates. The relative absolute deviations between the 2 estimates were on average 23% (se: 6%, with the errors in the observer–based distance estimates resembling that of a log-normal distribution. The linear regression of the observer–based estimates (obs on the image–based estimates (img was Obs=1.1Img (R2=0.85 with an intercept fixed at zero. There was no evidence of a distance estimation bias that could generate a positive bias in the absolute abundance estimated by cue–counting.

    Serum amyloid A protein (SAA) was isolated from mink, horse, and human serum by ultracentrifugation and gel filtration and characterized by two-dimensional gel electrophoresis, Western blotting followed by autoradiography and N-terminal amino acid analysis. SAA was found in similar quantities in the high density lipoprotein (HDL) fraction of serum from a patient suffering from systemic juvenile rheumatoid arthritis (JRA) and mink stimulated with lipopolysaccharide (LPS), and in somewhat smaller quantities in serum from horses stimulated with Escherichia coli cultures. Only very small quantities were present in normal human controls and not detectable in normal mink and horse. Striking similarities were found between human and mink SAA with respect to molecular weight, isolectric point and degree of heterogeneity, while the molecular weight, isolectric point and degree of heterogeneity, while the molecular weight of horse SAA seemed to be somewhat lower, and no obvious heterogeneity could be demonstrated in this protein using two-dimensional gel electrophoresis. Immunologic cross-reactivity between SAA from the three species was not found. In contrast to human and horse HDL, mink HDL was found not to contain apoA-II and only minute amounts of apoC proteins. Normal horse HDL also contained additional apoproteins not present in HDL from the other species. N-terminal amino acids analysis of SAA from mink and horse demonstrated the same similarity with the corresponding AA protein as previously reported for human SAA/AA

    2010-04-19

    Naturally occurring Sarcocystis neurona infection in a ferret (Mustela putorius furo) with rhinitis and disseminated disease are described for the first time. The ferret exhibited severe rhinitis with intra-lesional S. neurona merozoites and schizonts. Diagnosis was confirmed immunohistochemically by staining with S. neurona-specific antibodies, and by phylogenetic analyses of conserved and variable portions of nuclear ribosomal DNA. On the basis of intense schizogony in the nasal mucosa, we propose the possibility of an olfactory nerve pathway route of infection for S. neurona meningoencephalitis.

    2010-01-01

    Severe declines in megafauna worldwide illuminate the role of top predators in ecosystem structure. In the Antarctic, the Krill Surplus Hypothesis posits that the killing of more than 2 million large whales led to competitive release for smaller krill-eating species like the Antarctic minke whale. If true, the current size of the Antarctic minke whale population may be unusually high as an indirect result of whaling. Here, we estimate the long-term population size of the Antarctic minke whale prior to whaling by sequencing 11 nuclear genetic markers from 52 modern samples purchased in Japanese meat markets. We use coalescent simulations to explore the potential influence of population substructure and find that even though our samples are drawn from a limited geographic area, our estimate reflects ocean-wide genetic diversity. Using Bayesian estimates of the mutation rate and coalescent-based analyses of genetic diversity across loci, we calculate the long-term population size of the Antarctic minke whale to be 670,000 individuals (95% confidence interval: 374,000-1,150,000). Our estimate of long-term abundance is similar to, or greater than, contemporary abundance estimates, suggesting that managing Antarctic ecosystems under the assumption that Antarctic minke whales are unusually abundant is not warranted.

  5. Blood biochemical parameters in male American mink (Neovison vison before and during the breeding season

    Full Text Available This study was aimed at selected blood biochemical parameters in the male American mink before (September-November and during the breeding (January-March season. Blood from 143 Black and Sapphire male mink at one year age was collected. The plasma was assayed for the concentration of glucose, total protein, cholesterol, HDL and LDL fractions, triacylglycerides (TG, and the activity of ALT and AST. Concentrations of glucose, protein, total and HDL/LDL cholesterol, and AST activity were generally slightly higher during the breeding season than during the non-breeding season, but remained within the reference range. In the case of ALT activity and TG concentration, the relations were reversed. The parameters studied in the Sapphire mink showed greater variation, both in- and out of the season. In Black and Sapphire males of the American mink, the studied parameters revealed slightly higher values during the breeding season than the non-breeding season. This will vary depending on the color variety. The decrease in TG concentration during the breeding season may indicate an increased energy demand due to ambient temperature falls, and/or may be a sign of increased energy consumption associated with physical exertion during mating. Consideration should be given to the nutrition of male mink during the breeding season.

    Full Text Available Minke whale (Balaenoptera acutorostrata tissue (mainly blubber was found in the gastrointestinal tracks of Greenland sharks (Somniosus microcephalus collected in Kongsfjorden, Svalbard, Norway. In order to determine whether the sharks were actively hunting the whales, finding naturally dead whales or consuming offal from whaling, we checked the genetic identity of the whale tissue found in the sharks against the DNA register for minke whales taken in Norwegian whaling operations. All of the minke whale samples from the sharks that had DNA of sufficient quality to perform individual identifications were traceable to the whaling DNA register. During whaling operations, the blubber is stripped from the carcass and thrown overboard. The blubber strips float on the surface and are available for surface-feeding predators. This study revealed that Greenland sharks are scavenging this material; additionally, it demonstrates the capacity of this ‘benthic-feeding’ shark to utilize the whole water column for foraging.

    There are three major lineages of marine mammal strains of Brucella spp.: Brucella ceti ST23, found predominantly in porpoises; B. ceti ST26, in pelagic delphinids and ziphiids; and Brucella pinnipedialis ST24/25, predominantly in seals. The isolation of Brucella spp. in mysticetes has been described only in common minke whales ( Balaenoptera acutorostrata ) in Norway and Scotland. We report a third case of Brucella infection and isolation in a minke whale associated with a large abscess. In contrast to the two previous reports that involved isolates of B. pinnipedialis ST24 or the porpoise-associated B. ceti complex ST23, this case was associated with the dolphin-associated B. ceti ST26. Thus, minke whales can be infected naturally with members of all the distinct major lineages of Brucella associated with marine mammals. This report is unique in that the B. ceti ST26 did not originate from a pelagic delphinid or a beaked whale.

    Twenty-two mink frogs, Rana septentrionalis, collected from two locations in Minnesota, United States, were examined for helminth and protozoan blood parasites in July 1999. A total of 16 parasite taxa were recovered including 5 larval digenean trematodes, 7 adult digenean trematodes, 3 nematodes, and I Trypanosorna species. Infracommunities were dominated by the digeneans in terms of richness and abundance. In particular, echinostomatid metacercariae in the kidneys of frogs were the most common parasites found, infecting 100% of the frogs and consisting of about 90% of all helminth individuals recovered. Gorgodera amplicava, Gorgoderina multilohata, Haernaroloechus pan'iplexus, Haernatoloechus breviplexus, Cosnwcercoides dukae, and Oswaldocruzia pipiens represent new host records. The survey presented here represents the second known helminth survey of mink frogs conducted in North America. A summary of metazoan parasites reported from mink frogs is included.

Full-length sequence analysis (1824 nucleotides) of the variable hemagglutinin (H) gene were performed on 27 viruses collected from mink and on 7 viruses collected from wild foxes. Results of the study showed...... with other European canine distemper viruses and showed the highest level of similarity (99.3 - 99.6 %) to viruses isolated from wild foxes in Germany. The fox should therefore be considered as an important wild life reservoir of canine distemper virus and may also contribute to the transmission of the virus...

    The domestic ferret (Mustela putorius furo) is an important animal model for multiple human respiratory diseases. It is considered the 'gold standard' for modeling human influenza virus infection and transmission. Here we describe the 2.41 Gb draft genome assembly of the domestic ferret, constituting 2.28 Gb of sequence plus gaps. We annotated 19,910 protein-coding genes on this assembly using RNA-seq data from 21 ferret tissues. We characterized the ferret host response to two influenza virus infections by RNA-seq analysis of 42 ferret samples from influenza time-course data and showed distinct signatures in ferret trachea and lung tissues specific to 1918 or 2009 human pandemic influenza virus infections. Using microarray data from 16 ferret samples reflecting cystic fibrosis disease progression, we showed that transcriptional changes in the CFTR-knockout ferret lung reflect pathways of early disease that cannot be readily studied in human infants with cystic fibrosis disease.

    A major outbreak of canine distemper virus (CDV) in Danish farmed mink (Neovison vison) started in the late summer period of 2012. At the same time, a high number of diseased and dead wildlife species such as foxes, raccoon dogs, and ferrets were observed. To track the origin of the outbreak virus full-length sequencing of the receptor binding surface protein hemagglutinin (H) was performed on 26 CDV's collected from mink and 10 CDV's collected from wildlife species. Subsequent phylogenetic analyses showed that the virus circulating in the mink farms and wildlife were highly identical with an identity at the nucleotide level of 99.45% to 100%. The sequences could be grouped by single nucleotide polymorphisms according to geographical distribution of mink farms and wildlife. The signaling lymphocytic activation molecule (SLAM) receptor binding region in most viruses from both mink and wildlife contained G at position 530 and Y at position 549; however, three mink viruses had an Y549H substitution. The outbreak viruses clustered phylogenetically in the European lineage and were highly identical to wildlife viruses from Germany and Hungary (99.29% – 99.62%). The study furthermore revealed that fleas (Ceratophyllus sciurorum) contained CDV and that vertical transmission of CDV occurred in a wild ferret. The study provides evidence that wildlife species, such as foxes, play an important role in the transmission of CDV to farmed mink and that the virus may be maintained in the wild animal reservoir between outbreaks.

    2016-06-01

    Estimating the abundance or density of populations is fundamental to the conservation and management of species, and as landscapes become more fragmented, maintaining landscape connectivity has become one of the most important challenges for biodiversity conservation. Yet these two issues have never been formally integrated together in a model that simultaneously models abundance while accounting for connectivity of a landscape. We demonstrate an application of using capture-recapture to develop a model of animal density using a least-cost path model for individual encounter probability that accounts for non-Euclidean connectivity in a highly structured network. We utilized scat detection dogs (Canis lupus familiaris) as a means of collecting non-invasive genetic samples of American mink (Neovison vison) individuals and used spatial capture-recapture models (SCR) to gain inferences about mink population density and connectivity. Density of mink was not constant across the landscape, but rather increased with increasing distance from city, town, or village centers, and mink activity was associated with water. The SCR model allowed us to estimate the density and spatial distribution of individuals across a 388 km² area. The model was used to investigate patterns of space usage and to evaluate covariate effects on encounter probabilities, including differences between sexes. This study provides an application of capture-recapture models based on ecological distance, allowing us to directly estimate landscape connectivity. This approach should be widely applicable to provide simultaneous direct estimates of density, space usage, and landscape connectivity for many species.

    Influenza A viruses (IAVs) are negative-sense, single-stranded and segmented RNA viruses of the Orthomyxoviridae family that may cause acute respiratory disease in a wide range of birds and mammals. Susceptibility of several species within the family Mustelidae to IAVs has been reported as a result of natural or experimental infections. The objectives of this study were to assess whether free-ranging American mink populations from Northern Spain were infected with IAV and try to define the role of this species in the epidemiology of IAV. Sera from 689 American mink from Northern Spain captured between 2011 and 2014 were tested for the presence of antibodies against IAVs using a commercial competition cELISA. Positive sera were further analysed with haemagglutination inhibition (HI) assay. Fifteen of the 689 (2.2%, 1.3-3.6 CI 95% ) of the American minks analysed were ELISA positive. No significant differences were observed between years of capture, provinces, river basins, sexes or ages of the animals. All seropositive sera resulted negative to the panel strains used in the HI assay, showing that the most relevant strains circulating in swine, the most relevant avian subtypes (H5 and H7) and the H10N4 subtype isolated in minks have not been circulating in this free-ranging exotic carnivore from Spain. In the light of these results, the free-range American mink from Northern Spain do not seem to have an important role in the epidemiology of IAVs. © 2016 Blackwell Verlag GmbH.

    2014-01-01

    Background Since the recommendations on group housing of mink (Neovison vison) were adopted by the Council of Europe in 1999, it has become common in mink production in Europe. Group housing is advantageous from a production perspective, but can lead to aggression between animals and thus raises...... a welfare issue. Bite marks on the animals are an indicator of this aggressive behaviour and thus selection against frequency of bite marks should reduce aggression and improve animal welfare. Bite marks on one individual reflect the aggression of its group members, which means that the number of bite marks...... genetic effects contribute to variation in number of bite marks in group-housed mink. Thus, a genetic selection design that includes both direct genetic and indirect genetic effects could reduce the frequency of bite marks and probably aggression behaviour in group-housed mink....

    Canine Distemper Virus (CDV) infects many carnivores and cause several high-mortality disease outbreaks. The current CDV live vaccine cannot be safely used in some exotic species, such as mink and ferret. Here, we generated recombinant lentogenic Newcastle disease virus (NDV) LaSota expressing either envelope glycoproyein, heamagglutinine (H) or fusion protein (F), named as rLa-CDVH and rLa-CDVF, respectively. The feasibility of these recombinant NDVs to serve as live virus-vectored CD vaccine was evaluated in minks. rLa-CDVH induced significant neutralization antibodies (NA) to CDV and provided solid protection against virulent CDV challenge. On the contrast, rLa-CDVF induced much lower NA to CDV and fail to protected mink from virulent CDV challenge. Results suggest that recombinant NDV expressing CDV H is safe and efficient candidate vaccine against CDV in mink, and maybe other host species. Copyright © 2015 Elsevier Ltd. All rights reserved.

    Full Text Available The antioxidant influence on the physiological-biochemical parameters of productive animals is one of the most important directions in modern animal science. Phenozan is a synthetic antioxidant with high biological activities including those for animals. The positive effects of phenozan on the physiological-biochemical parameters of the mink blood were found. These effects are leading to the intensive growth, strong health, enhancement of the mink fur quality, and so forth. The total amount of the erythrocytes in the mink blood increased by about 4-5% due to phenozan inclusion in the mink diet. Even a more significant increase was found in hemoglobin content in the mink blood and erythrocytes (by about 9.5% and 8.8%, resp. due to phenozan inclusion of 100 mg/day, whereas it was found only by about 6.1–5.3% or 5.5–0.3%, owing to phenozan inclusion of 50 or 150 mg/day. For many other parameters the optimal phenozan concentration was about 100 mg/day per head according to the result obtained for all studied animal groups. Thus, phenozan can be successfully used as a biologically active compound for mink nutrition and is recommended for other farm animals.

    The minke whale (Balaenoptera acutorostrata) is the most common baleen whale among several marine mammal species observed in Korea. Since a high concentrated condition of prey to whales can be obtained by physical structures, the foraging whale distribution can be an indicator of biological hotspot. Our main objective is verifying the coastal upwelling-southwestern East Sea as a productive biological hotspot based on the geographical distribution of minke whales. Among the cetacean research surveys of the National Institute of Fisheries Science since 1999, 9 years data for the minke whales available in the East Sea were used for this study. The regional primary productivity derived from Moderate-Resolution Imaging Spectroradiometer (MODIS) was used for a proxy of biological productivity. Minke whales observed during the sighting surveys were mostly concentrated in May and found mostly (approximately 70%) in the southwestern coastal areas (whales was found in recent years, which indicate that the major habitats of mink whales have been shifted into the north of the common coastal upwelling regions. This is consistent with the recently reported unprecedented coastal upwelling in the mid-eastern coast of Korea. Based on high phytoplankton productivity and high distribution of minke whales, the southwestern coastal regions can be considered as one of biological hotspots in the East Sea. These regions are important for ecosystem dynamics and the population biology of top marine predators, especially migratory whales and needed to be carefully managed from a resource management perspective.

  20. Generation of Monoclonal Antibodies against Immunoglobulin Proteins of the Domestic Ferret (Mustela putorius furo)

    Science.gov (United States)

    2017-01-01

    The domestic ferret (Mustela putorius furo) serves as an animal model for the study of several viruses that cause human disease, most notably influenza. Despite the importance of this animal model, characterization of the immune response by flow cytometry (FCM) is severely hampered due to the limited number of commercially available reagents. To begin to address this unmet need and to facilitate more in-depth study of ferret B cells including the identification of antibody-secreting cells, eight unique murine monoclonal antibodies (mAb) with specificity for ferret immunoglobulin (Ig) were generated using conventional B cell hybridoma technology. These mAb were screened for reactivity against ferret peripheral blood mononuclear cells by FCM and demonstrate specificity for CD79β+ B cells. Several of these mAb are specific for the light chain of surface B cell receptor (BCR) and enable segregation of kappa and lambda B cells. Additionally, a mAb that yielded surface staining of nearly all surface BCR positive cells (i.e., pan ferret Ig) was generated. Collectively, these MαF-Ig mAb offer advancement compared to the existing portfolio of polyclonal anti-ferret Ig detection reagents and should be applicable to a wide array of immunologic assays including the identification of antibody-secreting cells by FCM.

    A 5-y-old female ferret (Mustela putorius furo) was evaluated for diarrhea, anorexia, and lethargy for 1 wk. Only mild dehydration was detected on physical examination. CBC analysis revealed marked erythrocytosis with an unremarkable plasma biochemistry panel; follow-up CBC analyses revealed a consistent primary erythrocytosis. Whole-body radiographs and abdominal ultrasonography were unremarkable except for a small nephrolith in the right kidney and a small cyst in the left kidney. The plasma erythropoietin level was 17.0 mIU/mL and considered normal. In light of the diagnostic work-up and consistent erythrocytosis, a diagnosis of polycythemia vera (primary erythrocytosis) was made. The initial presentation of diarrhea resolved after treatment with oral metronidazole (20 mg/kg PO BID for 7 d). Treatment for the polycythemia consisted of a phlebotomy initially followed by chemotherapy with hydroxyurea (10 mg/kg PO BID). During the subsequent 12 mo, the hydroxyurea dose adjusted according to follow-up CBC results, and finding an optimal dosage regimen proved to be challenging. One year after the initial diagnosis, the ferret presented to an emergency clinic for acute and severe hemorrhagic diarrhea and died shortly thereafter. The postmortem diagnosis was acute venous infarction of the small and large intestine. To our knowledge, this report is the first to describe the diagnosis and long-term management of polycythemia vera in a ferret and the use of hydroxyurea for this purpose.

    A 5-month-old, intact male ferret (Mustela putorius furo) was presented with apathy, tachypnea and exercise intolerance. On initial physical examination, tachypnea and cyanosis were the two primary clinical signs detected. The complete blood count also revealed a severe polycythemia, with lymphopenia, neutrophilia and eosinophilia. Further diagnostic imaging tests were performed. The thoracic radiographs revealed cardiomegaly and a diffuse alveolar pulmonary pattern. Consequently, an echocardiography was performed and showed an interventricular septal defect, pulmonic artery occlusion, overriding of the aorta and right ventricle hypertrophy. All abnormalities were compatible with a tetralogy of Fallot (TOF). As a treatment plan, a phlebotomy was performed and the ferret was posteriorly maintained with oxygen and fluid therapy. The following day, the hematocrit decreased 11% and the respiratory distress improved. Four days later, the ferret got clinically worse and was euthanized. A necropsy was performed and confirmed the presence of an extreme TOF with a diffused interstitial pneumonia secondary to Pneumocystis carinii. To the author's knowledge, this is the first report of an extreme tetralogy of Fallot with polycythemia in a ferret. Copyright © 2017 Elsevier Inc. All rights reserved.

    We exposed naive Siberain polecats (Mustela eversmanni) (aged 2, 3, and 4 months) to a swooping stuffed great horned owl (Buho virginianus) and a stuffed badger (Taxidae taxus) mounted on a remote control toy automobile frame. The first introduction to each was harmless, the second was accompanied by a mild aversive stimulus, the third (1 day after attack) was harmless, and the fourth (30 days after attack) was harmless. Alert behavior increased after a single attack by either predator model. Escape responses of naive polecats did not differ between ages when exposed to the badger, but 4 month old polecats reduced their escape times after a single badger attack. When exposed to the swooping owl, naive 4 month old polecats redponded more quickly than the other two age groups, and 3 and 4 month old polecats reduced escape times after a single owl attack. This indicates an innate escape response to the owl model at 4 months of age, and a short-tert ability to remember a single mild aversive encounter with the badger and owl models at 3 or 4 months of age.

    Eosinophilic gastroenteritis, focal or diffuse with eosinophilic infiltrations of the stomach or intestine, has been described in human beings, cats, dogs, and horses. In this paper, we describe infiltration of the gastrointestinal tract with eosinophils accompanied by a circulating eosinophilia in six ferrets (Mustela putorius furo). Clinical signs included chronic weight loss, anorexia, and diarrhea. The small intestines from five ferrets had diffuse infiltrates of eosinophils. This resulted in focal or multifocal loss of the muscular tunic in three ferrets. Two of these ferrets also had eosinophilic gastritis. Eosinophilic granulomas with Splendore-Hoeppli material were present in mesenteric lymph nodes in four ferrets. Two ferrets had multiple organ involvement; one had eosinophilic granulomas in the liver, mesentery, and choroid plexus as well as moderate parapancreatic segmental arteritis with infiltration of eosinophils and mural thrombosis. The second ferret had, in addition to moderate diffuse gastric and small intestinal eosinophilic mucosal infiltrations, interstitial eosinophilic pulmonary infiltrates. Examination of all tissues failed to reveal an infectious agent.

    BACKGROUND: Recently fibroblasts of many mammalian species have been reprogrammed to pluripotent state using overexpression of several transcription factors. This technology allows production of induced pluripotent stem (iPS) cells with properties similar to embryonic stem (ES) cells....... The completeness of reprogramming process is well studied in such species as mouse and human but there is not enough data on other species. We produced American mink (Neovison vison) ES and iPS cells and compared these cells using transcriptome analysis. RESULTS: We report the generation of 10 mink ES and 22 i......PS cell lines. The majority of the analyzed cell lines had normal diploid chromosome number. The only ES cell line with XX chromosome set had both X-chromosomes in active state that is characteristic of pluripotent cells. The pluripotency of ES and iPS cell lines was confirmed by formation of teratomas...

    Full Text Available Abstract A virus was isolated from mink showing clinical and pathological signs of enteritis in China. This virus, designated MEV/LN-10, was identified as mink enteritis virus (MEV based on its cytopathic effect in the feline F81 cell line, the hemagglutination (HA and hemagglutination inhibition (HI assay, electron microscopy (EM and animal infection experiments. The complete viral genome was cloned and sequenced. Phylogenetic and recombination analyses on the complete MEV/LN-10 genome showed evidence of recombination between MEV and canine parvovirus (CPV. The genome was composed of the NS1 gene originating from CPV while the VP1 gene was of MEV origin. This is the first demonstration of recombination between a CPV and MEV in nature. Our findings not only provide valuable evidence indicating that recombination is an important genetic mechanism contributing to the variation and evolution of MEV, but also that heterogeneous recombination can occur in the feline parvovirus subspecies.

    Full Text Available North Atlantic Sightings Surveys for cetaceans were carried out Northeast and Central Atlantic in 1987, 1989, 1995 and 2001. Here we provide estimates of density and abundance for minke whales from the Faroese and Icelandic ship surveys. The estimates are not corrected for availability or perception biases. Double platform data collected in 2001 indicates that perception bias is likely considerable for this species. However comparison of corrected estimates of densityfrom aerial surveys with a ship survey estimate from the same area suggests that ship surveys can be nearly unbiased under optimal survey conditions with high searching effort. There were some regional changes in density over the period but no overall changes in density and abundance. Given the recent catch history for minke whales in this area, we would not expect to see changes in abundance due to exploitation that would be detectable with these surveys.

    Canine distemper virus (CDV) infects a broad range of carnivores and causes a highly contagious disease with severe immunosuppression. The disease severity markedly varies in different species. To investigate the pathogenesis of CDV in raccoon dog (Nyctereutes procyonoides), fox (Vulpes vulpes) and mink (Neovison vison) species, three groups of CDV sero-negative animals were infected with CDV strain LN(10)1. This CDV strain belongs to the Asia-1 genotype, which is epidemiologically predominant in carnivores in China. CDV infection provoked marked differences in virulence in the three species that were studied. Raccoon dogs developed fever, severe conjunctivitis, and pathological lesions, with 100% (5/5) mortality and with high viral RNA loads in organs within 15 days post infection (dpi). In infected foxes, the onset of the disease was delayed, with 40% (2/5) mortality by 21 dpi. Infected minks developed only mild clinical signs and pathological lesions, and mortality was not observed. Raccoon dogs and foxes showed more severe immune suppression (lymphopenia, decreased lymphocyte proliferation, viremia and low-level virus neutralizing antibodies) than minks. We also observed a distinct pattern of cytokine mRNA transcripts at different times after infection. Decreased IFN-γ and IL-4 mRNA responses were evident in the animals with fatal disease, while up-regulation of these cytokines was observed in the animals surviving the infection. Increased TNF-α response was detected in animals with mild or severe clinical signs. Based on the results, we could distinguish three different patterns of disease after experimental CDV infection, e.g. a mild form in minks, a moderate form in foxes and a severe disease in raccoon dogs. The observed differences in susceptibility to CDV could be related to distinct host cytokine profiles. Comparative evaluation of CDV pathogenesis in various animal species is pivotal to generate models suitable for the evaluation of CDV

    Atlantic minke whales are important predators in the Barents Sea ecosystem; capelin Mallotus villosus, krill Thysanoessa sp. and Meganyctephanes norvegica and herring Clupea harengus are their major prey. Their consumption of commercial species may present an economic problem for the local fishery. In order to estimate this consumption and understand the potential consequences for prey dynamics, it is essential to determine the multispecies functional response of the whales.

    Full Text Available Canine distemper virus (CDV, a paramyxovirus, causes a severe highly contagious lethal disease in carnivores, such as mink. Mink lung epithelial cells (Mv.1.Lu cells are sensitive to CDV infection and are homologous to the natural host system of mink. The current study analyzed the response of Mv.1.Lu cells to CDV infection by iTRAQ combined with LC–MS/MS. In total, 151 and 369 differentially expressed proteins (DEPs were markedly up-regulated or down-regulated, respectively. Thirteen DEPs were validated via real-time RT-PCR or western blot analysis. Network and KEGG pathway analyses revealed several regulated proteins associated with the NF-κB signaling pathway. Further validation was performed by western blot analysis and immunofluorescence assay, which demonstrated that different CDV strains induced NF-κB P65 phosphorylation and nuclear translocation. Moreover, the results provided interesting information that some identified DEPs possibly associated with the pathogenesis and the immune response upon CDV infection. This study is the first overview of the responses to CDV infection in Mv.1.Lu cells, and the findings will help to analyze further aspects of the molecular mechanisms involved in viral pathogenesis and the immune responses upon CDV infection.

    Canine distemper virus (CDV) is highly contagious and can cause severe disease against which conventional live vaccines are ineffective in the presence of maternal antibodies. Vaccination in the presences of maternal antibodies was challenged by vaccination of 5 days old and 3 weeks old mink kits with CDV DNA vaccines. Virus neutralising (VN) antibody responses were induced in mink kits vaccinated with a plasmid encoding the haemaglutinin protein (H) of CDV (n=5, pCDV-H) or a combination of the H, fusion (F) and nucleoprotein (N) of CDV (n=5, pCDV-HFN). These DNA vaccinated kits were protected against virulent experimental infection with field strains of CDV. The pCDV-H was more efficient in inducing protective immunity in the presence of maternal antibodies compared to the pCDV-HFN. The results show that DNA vaccination with the pCDV-H or pCDV-HFN (n=4) only given once at 5 days of age induces virus specific immune response in neonatal mink and protection against virulent CDV exposure later in life.

    During 8 months from July 2012 to February 2013, a major outbreak of canine distemper involving 64 mink farms occurred on the Danish peninsula of Jutland. The canine distemper outbreak was associated with exposure of farmed mink to infected wild carnivores and could represent a deficit in biosecurity on the mink farms. The aim of this study was to investigate the extent and association of specific biosecurity measures with the outbreak. The study was carried out in an epidemiological case-control design. The case group consisted of the 61 farms, which had a confirmed outbreak of canine distemper from July 2012 to February 2013. The control group included 54 farms without an outbreak of canine distemper in 2012 or 2013, selected as the closest geographical neighbour to a case farm. The results showed that significantly more control than case farms had vaccinated their mink against canine distemper virus. Mortality was only assessed on the case farms, and there was a non-significantly lower mortality on vaccinated farms than on the non-vaccinated farms. Furthermore, the proportion of farms with observations of wild red foxes (Vulpes vulpes) inside the farm enclosures were larger for case farms, indicating that the control farms had a better biosecurity or were not equally exposed to canine distemper virus. Generally, all farms had very few specific precautions at the gate entrance in respect to human visitors as well as animals. The use of biosecurity measures was very variable in both case and control farms. Not using plastic boot covers, presence of dogs and cats, presence of demarcated area for changing clothes when entering and leaving the farm area and presence of hand washing facilities significantly lowered the odds of the farm having a canine distemper virus outbreak. The results of the study indicate that consistent use of correct vaccination strategies, implementation of biosecurity measures and limiting human and animal access to the mink farm can be

    As a component of an ecological risk assessment of Poplar Creek (located on the Oak Ridge Reservation [ORR]) and the Clinch River (a large river-reservoir system), fish from Poplar Creek, the Clinch River, and Atlantic Ocean were fed to ranch mink to evaluate reproductive success. Five diets, each composed of 75% fish and 25% normal ranch mink chow, were prepared. Two diets served as reference diets and contained 75% Atlantic Ocean fish or 75% Clinch River fish collected above the ORR. The fish portion of the remaining three diets contained 25, 50, and 75% fish collected from Poplar Creek and 50, 25, and 0% ocean fish, respectively. Five mink groups (eight females and two males each) were each fed one of the prepared diets for 196 days. Polychlorinated biphenyl concentrations were determined in diets and various mink tissues, ethoxyresorufin-O-deethylase (EROD) activity was determined in liver tissue, and reproductive success was evaluated. Concentrations of PCB were greatest in the diet composed of 75% Poplar Creek fish and in tissues from mink fed this diet and their offspring. There was a trend toward decreased adult female and kit weights and reduced mean litter size in mink fed diets containing 75% Poplar Creek fish; however, at 6 weeks of age, kit survival was similar among diet groups. Liver EROD activity significantly increased in adult female mink fed 50 and 75% Poplar Creek fish diets. Estimated dietary concentrations of PCBs were similar to or slightly lower than concentrations associated with adverse effects in experimentally dosed mink. Mercury (Hg) concentrations previously reported in these same mink were below that associated with adverse effects, and there was no indication of additive or synergistic effects from exposure to PCBs plus Hg. It is unlikely that population-level reproductive effects would be observed in mink consuming fish from Poplar Creek on the ORR

    Pre-weaning diarrhea in mink, also known as "sticky kits", is a syndrome and outbreaks occur every year on commercial mink farms in all mink producing countries. Morbidity and mortality can be considerable on a farm with huge economic consequences for the farmer as well as compromised welfare for the mink kits. Although efforts have been taken to identify etiologic agents involved in outbreaks, the syndrome is still regarded as multifactorial and recurring problems on the same farms draw attention to management and environmental risk factors. In the pre-weaning period from May to June 2015, a case control study was carried out on 30 Danish mink farms. Data concerning management, biosecurity, hygiene, feed consumption, antibacterial prescription and production efficiency were analyzed. The proportion of 1-year old females, farm size (total number of females), energy supply per female in the late gestation period, and dogs accessing the farm area were significantly associated with being a case farm. Case farms were prescribed almost twice the amount of antibacterials per gestational unit (female and litter) as in control farms. Farmers on case farms spent significantly more time nursing and treating the animals and experienced more females with mastitis compared to farmers on control farms. No significant differences in cleaning practices or hygienic measures between case and control farms were found and there were no differences in drinking water quality, bedding material, composition neither of color types nor in management regarding litter equalization. Results from this study showed an association between the occurrence of pre-weaning diarrhea on mink farms and parity profile, farm size and feeding intensity in the gestational period. The access of dogs to the farm area was a significant risk factor, but needs further clarification.

  19. Isolation and characterization of a "phiKMV-like" bacteriophage and its therapeutic effect on mink hemorrhagic pneumonia.

    Full Text Available The objective of this study was to investigate the potential of using phages as a therapy against hemorrhagic pneumonia in mink both in vitro and in vivo. Five Pseudomonas aeruginosa (P. aeruginosa strains were isolated from lungs of mink with suspected hemorrhagic pneumonia and their identity was confirmed by morphological observation and 16S rDNA sequence analysis. Compared to P. aeruginosa strains isolated from mink with hemorrhagic pneumonia in 2002, these isolates were more resistant to antibiotics selected. A lytic phage vB_PaeP_PPA-ABTNL (PPA-ABTNL of the Podoviridae family was isolated from hospital sewage using a P. aeruginosa isolate as host, showing broad host range against P. aeruginosa. A one-step growth curve analysis of PPA-ABTNL revealed eclipse and latent periods of 20 and 35 min, respectively, with a burst size of about 110 PFU per infected cell. Phage PPA-ABTNL significantly reduced the growth of P. aeruginosa isolates in vitro. The genome of PPA-ABTNL was 43,227 bp (62.4% G+C containing 54 open reading frames and lacked regions encoding known virulence factors, integration-related proteins and antibiotic resistance determinants. Genome architecture analysis showed that PPA-ABTNL belonged to the "phiKMV-like Viruses" group. A repeated dose inhalational toxicity study using PPA-ABTNL crude preparation was conducted in mice and no significantly abnormal histological changes, morbidity or mortality were observed. There was no indication of any potential risk associated with using PPA-ABTNL as a therapeutic agent. The results of a curative treatment experiment demonstrated that atomization by ultrasonic treatment could efficiently deliver phage to the lungs of mink and a dose of 10 multiplicity of infection was optimal for treating mink hemorrhagic pneumonia. Our work demonstrated the potential for phage to fight P. aeruginosa involved in mink lung infections when administered by means of ultrasonic nebulization.

    The aim of the study was to investigate the different phases of the immune response after DNA immunization with the hemagglutinin and nucleoprotein genes from canine distemper virus (CDV). Although attenuated live CDV vaccines have effectively reduced the incidence of disease, canine distemper is still a problem worldwide. The broad host range of CDV creates a constant viral reservoir among wildlife animals. Our results demonstrated early humoral and cell-mediated immune responses (IFN-gamma) in DNA vaccinated mink compared to mock-vaccinated mink after challenge with a Danish wild-type CDV. The DNA vaccine-induced immunity protected the natural host against disease development.

    Aleutian mink disease is the most important disease in the mink-farming industry worldwide. So far, few large-scale molecular epidemiological studies of AMDV, based on the NS1 and VP2 genes, have been conducted in China. Here, eight new Chinese isolates of AMDV from three provinces in north-east China were analyzed to clarify the molecular epidemiology of AMDV. The seroprevalence of AMDV in north-east China was 41.8% according to counterimmuno-electrophoresis. Genetic variation analysis of the eight isolates showed significant non-synonymous substitutions in the NS1 and VP2 genes, especially in the NS1 gene. All eight isolates included the caspase-recognition sequence NS1:285 (DQTD↓S), but not the caspase recognition sequence NS1:227 (INTD↓S). The LN1 and LN2 strains had a new 10-amino-acid deletion in-between amino acids 28-37, while the JL3 strain had a one-amino-acid deletion at position 28 in the VP2 protein, compared with the AMDV-G strain. Phylogenetic analysis based on most of NS1 (1755 bp) and complete VP2 showed that the AMDV genotypes did not cluster according to their pathogenicity or geographic origin. Local and imported ADMV species are all prevalent in mink-farming populations in the north-east of China. This is the first study to report the molecular epidemiology of AMDV in north-east China based on most of NS1 and the complete VP2, and further provides information about polyG deletions and new variations in the amino acid sequences of NS1 and VP2 proteins. This report is a good foundation for further study of AMDV in China.

    Women who are pregnant and homeless constitute a unique group at significant risk of adverse foetal and maternal outcomes. Despite this heightened risk profile, social housing support to this group of women is less than satisfactory. Concerted effort and more collaborative working is needed by all who provide social, and healthcare services to homeless pregnant women, to improve the lot of these women. Clear definitions and legislative provisions in respect of the homeless will go a long way in reducing ambiguity and close loopholes which currently act to deny the homeless pregnant woman social housing support at a time when it is most needed.

    Black-footed ferrets (Mustela nigripes) require extensive prairie dog colonies (Cynomys spp.) to provide habitat and prey. Epizootic plague kills both prairie dogs and ferrets and is a major factor limiting recovery of the highly endangered ferret. In addition to epizootics, we hypothesized that enzootic plague, that is, presence of disease-causing Yersinia pestis without any noticeable prairie dog die off, may also affect ferret survival. We reduced risk of plague on portions of two ferret reintroduction areas by conducting flea control for 3 years. Beginning in 2004, about half of the ferrets residing on dusted and nondusted colonies were vaccinated against plague with an experimental vaccine (F1-V fusion protein). We evaluated 6-month reencounter rates (percentage of animals observed at the end of an interval that were known alive at the beginning of the interval), an index to survival, for ferrets in four treatment groups involving all combinations of vaccination and flea control. For captive-reared ferrets (115 individuals observed across 156 time intervals), reencounter rates were higher for vaccinates (0.44) than for nonvaccinates (0.23, p = 0.044) on colonies without flea control, but vaccination had no detectable effect on colonies with flea control (vaccinates = 0.41, nonvaccinates = 0.42, p = 0.754). Flea control resulted in higher reencounter rates for nonvaccinates (p = 0.026), but not for vaccinates (p = 0.508). The enhancement of survival due to vaccination or flea control supports the hypothesis that enzootic plague reduces ferret survival, even when there was no noticeable decline in prairie dog abundance. The collective effects of vaccination and flea control compel a conclusion that fleas are required for maintenance, and probably transmission, of plague at enzootic levels. Other studies have demonstrated similar effects of flea control on several species of prairie dogs and, when combined with this study, suggest

    Farmed mink (Neovison vison) is one of the most important fur-bearing species worldwide, and coat colour is a crucial qualitative characteristic that contributes to the economic value of the fur. To identify additional genes that may play important roles in coat colour regulation, Illumina/Solexa high-throughput sequencing technology was used to catalogue the global gene expression profiles in mink skin with two different coat colours (black and white). RNA-seq analysis indicated that a total of 12,557 genes were differentially expressed in black versus white minks, with 3,530 genes up-regulated and 9,027 genes down-regulated in black minks. Significant differences were not observed in the expression of MC1R and TYR between the two different coat colours, and the expression of ASIP was not detected in the mink skin of either coat colour. The expression levels of KITLG, LEF1, DCT, TYRP1, PMEL, Myo5a, Rab27a and SLC7A11 were validated by qRT-PCR, and the results were consistent with RNA-seq analysis. This study provides several candidate genes that may be associated with the development of two coat colours in mink skin. These results will expand our understanding of the complex molecular mechanisms underlying skin physiology and melanogenesis in mink and will provide a foundation for future studies.

    CASE DESCRIPTION A 10-week-old 0.73-kg (1.6-lb) castrated male domestic ferret (Mustela putorius furo) was referred for exploratory laparotomy because of pneumoperitoneum and possible septic peritonitis after being bitten by the owner's dog. CLINICAL FINDINGS Abdominal exploration revealed a large laceration of the duodenum, tears of the jejunal mesentery, and 2 small tears in the abdominal wall. Chylous abdominal effusion developed 48 hours after surgery. TREATMENT AND OUTCOME Postoperative care included supportive treatment, analgesia, and antimicrobials. An abdominal drain was placed during the laparotomy and enabled monitoring of abdominal fluid production. Enteral feeding was provided through an esophagostomy tube. The chylous fluid production rapidly decreased after treatment with octreotide was initiated, and the ferret improved. Chyloabdomen resolved after 8 days of hospitalization and medical treatment. CLINICAL RELEVANCE Findings suggested that chylous ascites can potentially develop secondary to blunt abdominal trauma in ferrets. In this ferret, chyloabdomen was successfully treated with octreotide administration and abdominal drainage.

    Full Text Available The work aimed at the analysis of the factors that influence conformation traits, included animal size and fur quality traits in four colour types of mink: standard, pastel, platinum and white Hedlunda. The data concerns the evaluation of animal conformation traits in the period of three years. The analysis of variance of particular traits indicates statistically significant effect of the year of birth, colour type and animal sex on the majority of analysed traits. Higher means of license evaluation were obtained by males in majority of the traits. Statistic analysis of body weight showed that the highest body weight characterized males of platinum and white Hedlunda colour types. Minks of standard and pastel colour types were characterised by lower body weight. The mean body weight of males was 2581.17g and of females 1401.42g (there is a clear sexual dimorphism in minks. Minks of white Hedlunda colour type were characterised by the highest means of colour purity, both males and females. Other colour types obtained lower means. The best fur quality characterised platinum minks. Variability of traits, measured by variability coefficient, had the highest values in animal weight (in grams and ranged from 6.0 to 32.0%. Variability of total number of scores ranged from 2.00 to 8.20%. Positive phenotypic correlations were the highest between body size (in points and total number of scores (0.676, while the lowest were obtained between body size (in points and fur quality (–0.178.

    The current study analyzed the nuclear organization of the neural systems related to the control and regulation of sleep and wake in the basal forebrain, diencephalon, midbrain, and pons of the minke whale, a mysticete cetacean. While odontocete cetaceans sleep in an unusual manner, with unihemispheric slow wave sleep (USWS) and suppressed REM sleep, it is unclear whether the mysticete whales show a similar sleep pattern. Previously, we detailed a range of features in the odontocete brain that appear to be related to odontocete-type sleep, and here present our analysis of these features in the minke whale brain. All neural elements involved in sleep regulation and control found in bihemispheric sleeping mammals and the harbor porpoise were present in the minke whale, with no specific nuclei being absent, and no novel nuclei being present. This qualitative similarity relates to the cholinergic, noradrenergic, serotonergic and orexinergic systems, and the GABAergic elements of these nuclei. Quantitative analysis revealed that the numbers of pontine cholinergic (274,242) and noradrenergic (203,686) neurons, and hypothalamic orexinergic neurons (277,604), are markedly higher than other large-brained bihemispheric sleeping mammals. Small telencephalic commissures (anterior, corpus callosum, and hippocampal), an enlarged posterior commissure, supernumerary pontine cholinergic and noradrenergic cells, and an enlarged peripheral division of the dorsal raphe nuclear complex of the minke whale, all indicate that the suite of neural characteristics thought to be involved in the control of USWS and the suppression of REM in the odontocete cetaceans are present in the minke whale.

    2011-01-01

    Nine skull samples of the beaver Castor fiber, six samples of the raccoon dog Nyctereutes procyonoides, and six samples of the American mink Neovison vison were studied using phenetic and craniometric methods. Analysis of the phenofund structure suggests that in all of the studied species the emergence of novel character variations does not lead to their fixation with a significant frequency. Considerable morphological variability emerges in the contact zone of different autochtonous populations, of wild and breeding forms, as well as in geographically and reproductively isolated small groups of individuals. Morphological differences of introduced animals fit into the conception of species polymorphism and are smoothed over when separate colonies merge into metapopulations, which does not lead to the emergence of novel stable taxa.

  14. Environmentally enriched male mink gain more copulations than stereotypic, barren-reared competitors.

    Directory of Open Access Journals (Sweden)

    María Díez-León

    Full Text Available Wild carnivores in zoos, conservation breeding centres, and farms commonly live in relatively small, unstimulating enclosures. Under these captive conditions, in a range of species including giant pandas, black-footed ferrets, and European mink, male reproductive abilities are often poor. Such problems have long been hypothesized to be caused by these animals' housing conditions. We show for the first time that rearing under welfare-improving (i.e., highly valued and stress-reducing environmental enrichments enhances male carnivores' copulatory performance: in mate choice competitions, enriched male American mink (Neovison vison mated more often than non-enriched males. We screened for several potential mediators of this effect. First was physiological stress and its impact on reproductive physiology; second, stress-mediated changes in morphology and variables related to immunocompetence that could influence male attractiveness; and third, behavioural changes likely to affect social competence, particularly autistic-like excessive routine and repetition ('perseveration' as is reflected in the stereotypies common in captive animals. Consistent with physiological stress, excreted steroid metabolites revealed that non-enriched males had higher cortisol levels and lower androgen levels than enriched conspecifics. Their os penises (bacula also tended to be less developed. Consistent with reduced attractiveness, non-enriched males were lighter, with comparatively small spleens and a trend to greater fluctuating asymmetry. Consistent with impaired social competence, non-enriched males performed more stereotypic behaviour (e.g., pacing in their home cages. Of all these effects, the only significant predictor of copulation number was stereotypy (a trend suggesting that low bodyweights may also be influential: highly stereotypic males gained the fewest copulations. The neurophysiological changes underlying stereotypy thus handicap males sexually. We

    2015-12-01

    Full Text Available The aim of the study was to determine the mechanical and geometric properties as well as bone tissue density of long bones in primiparous and multiparous dams of minks supplemented with β-hydroxy β-methylbutyrate (HMB and/or 2-oxoketoglutarate (2-Ox during gestation. Powdered 2-Ox was given at the daily dosage of 0.4 g/kg b.w. separately or simultaneously with HMB, which was administered at the daily dosage of 0.02 g/kg b.w. The study demonstrates for the first time that administration of 2-Ox and/or HMB to dams markedly influences bone tissue density and the mechanical and geometrical properties of mother`s bones in minks. Moreover, it was demonstrated that the supplementation was more effective in the thoracic limb, which was comprehensively used in contrast to the pelvic limb. The mechanical parameters and bone tissue density significantly increased in the humerus in multiparous minks. Only such diet may provide satisfactory production results in the animals. Nutritional deficiencies occurring during pregnancies may trigger body`s own reserves to cover the bone mass increase in developing foetuses and support milk production. This can prevent regeneration of dams’ organisms, which negatively affects their reproductive performance. 2-Ox or HMB may be regarded as a protective metabolite when administered orally to minks, counteracting the negative influences of pregnancy and lactation periods on bones condition. Both simultaneous treatment with 2-Ox and HMB and their separate administration were equally effective.

    Eradication and population reductions are often used to mitigate the negative impacts of non-native invasive species on native biodiversity. However, monitoring the effectiveness of non-native species control programmes is necessary to evaluate the efficacy of these measures. Genetic monitoring could provide valuable insights into temporal changes in demographic, ecological, and evolutionary processes in invasive populations being subject to control programmes. Such programmes should cause a decrease in effective population size and/or in genetic diversity of the targeted non-native species and an increase in population genetic structuring over time. We used microsatellite DNA data from American mink (Neovison vison) to determine whether the removal of this predator on the Koster Islands archipelago and the nearby Swedish mainland affected genetic variation over six consecutive years of mink culling by trappers as part of a population control programme. We found that on Koster Islands allelic richness decreased (from on average 4.53 to 3.55), genetic structuring increased, and effective population size did not change. In contrast, the mink population from the Swedish coast showed no changes in genetic diversity or structure, suggesting the stability of this population over 6 years of culling. Effective population size did not change over time but was higher on the coast than on the islands across all years. Migration rates from the islands to the coast were almost two times higher than from the coast to the islands. Most migrants leaving the coast were localised on the southern edge of the archipelago, as expected from the direction of the sea current between the two sites. Genetic monitoring provided valuable information on temporal changes in the population of American mink suggesting that this approach can be used to evaluate and improve control programmes of invasive vertebrates.

    Full Text Available Eradication and population reductions are often used to mitigate the negative impacts of non-native invasive species on native biodiversity. However, monitoring the effectiveness of non-native species control programmes is necessary to evaluate the efficacy of these measures. Genetic monitoring could provide valuable insights into temporal changes in demographic, ecological, and evolutionary processes in invasive populations being subject to control programmes.

    Approaches employed in counseling pregnant adolescents at the Crittenton Clinic in Boston are described. Concentrating on concrete issues of management of the pregnancy -- supplying information and exploring the pros and cons of various alternatives are advocated; probing into the psychological and emotional background of the pregnant adolescent is discouraged. Counseling about contraceptives and taking into account each individual situation are considered essential. Case studies are reviewed and figures representing the attitudes and contraceptive use of patients 1 year after abortion are presented. It is considered important to establish a trusting relationship with the adolescent, which will increase the likelihood that she will return for follow-up and additional help if she needs it.

    Various detection methods have been developed to date for identification of animal species. New techniques based on PCR approach have raised the hope of developing better identification methods, which can overcome the limitations of the existing methods. PCR-based methods used the mitochondrial DNA (mtDNA) as well as nuclear DNA sequences. In this study, by targeting nuclear DNA, multiplex PCR and real-time PCR methods were developed to assist with qualitative and quantitative analysis. The multiplex PCR was found to simultaneously and effectively distinguish four species (fox, dog, mink, and rabbit) ingredients by the different sizes of electrophoretic bands: 480, 317, 220, and 209 bp. Real-time fluorescent PCR's amplification profiles and standard curves showed good quantitative measurement responses and linearity, as indicated by good repeatability and coefficient of determination R 2  > 0.99. The quantitative results of quaternary DNA mixtures including mink, fox, dog, and rabbit DNA are in line with our expectations: R.D. (relative deviation) varied between 1.98 and 12.23% and R.S.D. (relative standard deviation) varied between 3.06 and 11.51%, both of which are well within the acceptance criterion of ≤ 25%. Combining the two methods is suitable for the rapid identification and accurate quantification of fox-, dog-, mink-, and rabbit-derived ingredients in the animal products.

    The aim of this work was the evaluation of the scale of violence towards pregnant women in the westpomeranian province, the definition of the social-biological profile of women exposed to violence and social-biological profile of their partners. The evaluation of the influence of violence on pregnant women's ending term and the weight of the newborns. 481 women were enrolled and an anonymous study was used in the form of questionnaires. A questionnaire was a modified form of a query-sheet proposed by WHO. 25% of the enrolled women were exposed to physical and psychological (emotional) abuse, 7.1% to psychical violence, women and men exposed to violence in their childhood more often become violent in their adult life. Men that physically abuse pregnant women are often of primary school education, are unemployed, drink alcohol and smoke. Physical abuse by a partner during pregnancy usually experience women with primary school education, who drink and smoke. Violence during pregnancy is usually associated with premature delivery as well as low birth weight of the newborns.

    American mink (Neovison vison) develop fatty liver quickly in response to food deprivation, which results in preferential mobilisation of n-3 PUFA. The altered n-3:n-6 PUFA ratio in the liver may activate the endocannabinoid system resulting in increased lipid synthesis. The objective of the present study was to investigate the effects of feeding intensity (80 or 120% RDA), dietary fat source (n-3, n-6 or n-9 fatty acids (FA)) and short-term fasting (1-7 d) on hepatic de novo lipogenesis (DNL) and the development of fatty liver in mink. Significantly elevated expression of mRNA encoding for acetyl-CoA carboxylase-1 (ACC-1) and FA synthase (FAS) was observed in the liver of mink fasted for 5-7 d, while upon re-feeding for 28 d after a 7 d food deprivation, DNL returned to pre-fasting levels. The females had a higher expression of ACC-1 and FAS mRNA than the males. In the non-fasted animals, dietary fat source and feeding intensity had significant effects on ACC-1 mRNA. The highest levels were observed in the mink fed the rapeseed oil (n-9) diet at 80% RDA, while the lowest levels were seen when the same diet was fed at 120% RDA. For FAS, the highest gene expression was seen in the fasted mink fed at 80% RDA and the lowest in the non-fasted mink fed at 80%. It is concluded that short-term food deprivation induces hepatic lipidosis in mink and that during this process, hepatic DNL further exacerbates liver fat accumulation.

    Sylvatic plague is one of the major impediments to the recovery of the black-footed ferret ( Mustela nigripes ) because it decimates their primary prey species, prairie dogs ( Cynomys spp.), and directly causes mortality in ferrets. Fleas are the primary vector of Yersinia pestis , the causative agent of sylvatic plague. The goal of this research was to better understand the flea fauna of ferrets and the factors that might influence flea abundance on ferrets. Fleas from ferrets were tested for Y. pestis in a post hoc assessment to investigate the plausibility that some ferrets could act as incidental transporter hosts of fleas infected with Y. pestis . Fleas were collected from ferrets captured on the Lower Brule Indian Reservation in central South Dakota, US from 2009 to 2012. A total of 528 fleas collected from 67 individual ferrets were identified and tested for the presence of Y. pestis with a nested PCR assay. The predominant flea recovered from ferrets was Oropsylla hirsuta , a species that comprises 70-100% of the fleas recovered from prairie dogs and their burrows in the study area. Yersinia pestis was detected at low levels in fleas collected from ferrets with prevalence ranging from 0% to 2.9%; male ferrets harbored significantly more fleas than female ferrets. Six of 67 ferrets vaccinated against plague carried fleas that tested positive for Y. pestis , which suggests ferrets vaccinated against plague could inadvertently act as incidental transporter hosts of Y. pestis -positive fleas.

    Black-footed ferrets (Mustela nigripes) are highly susceptible to sylvatic plague, caused by the bacterium Yersinia pestis, and this disease has severely hampered efforts to restore ferrets to their historic range. A study was conducted to assess the efficacy of vaccination of black-footed ferrets against plague using a recombinant protein vaccine, designated F1-V, developed by personnel at the U.S. Army Medical Research Institute of Infectious Diseases. Seven postreproductive black-footed ferrets were immunized with the vaccine, followed by two booster immunizations on days 23 and 154; three control black-footed ferrets received a placebo. After the second immunization, antibody titers to both F1 and V antigen were found to be significantly higher in vaccinates than controls. On challenge with 7,800 colony-forming units of virulent plague by s.c. injection, the three control animals died within 3 days, but six of seven vaccinates survived with no ill effects. The seventh vaccinate died on day 8. These results indicate that black-footed ferrets can be immunized against plague induced by the s.c. route, similar to fleabite injection.

    Aim: We examined data for ermine (Mustela erminea) to test two sets of diversification hypotheses concerning the number and location of late Pleistocene refugia, the timing and mode of diversification, and the evolutionary influence of insularization. Location: Temperate and sub-Arctic Northern Hemisphere. Methods: We used up to two mitochondrial and four nuclear loci from 237 specimens for statistical phylogeographical and demographic analyses. Coalescent species-tree estimation used a Bayesian approach for clade divergence based on external mutation rate calibrations. Approximate Bayesian methods were used to assess population size, timing of divergence and gene flow. Results: Limited structure coupled with evidence of population growth across broad regions, including previously ice-covered areas, indicated expansion from multiple centres of differentiation, but high endemism along the North Pacific coast (NPC). A bifurcating model of diversification with recent growth spanning three glacial cycles best explained the empirical data. Main conclusions: A newly identified clade in North America indicated a fourth refugial area for ermine. The shallow coalescence of all extant ermine reflects a recent history of diversification overlying a deeper fossil record. Post-glacial colonization has led to potential contact zones for multiple lineages in north-western North America. A model of diversification of ermine accompanied by recent gene flow was marginally less well supported than a model of divergence of major clades in response to the most recent glacial cycles.

    Full Text Available Abstract Background Bacterial artificial chromosome (BAC libraries continue to be invaluable tools for the genomic analysis of complex organisms. Complemented by the newly and fast growing deep sequencing technologies, they provide an excellent source of information in genomics projects. Results Here, we report the construction and characterization of the CHORI-231 BAC library constructed from a Danish-farmed, male American mink (Neovison vison. The library contains approximately 165,888 clones with an average insert size of 170 kb, representing approximately 10-fold coverage. High-density filters, each consisting of 18,432 clones spotted in duplicate, have been produced for hybridization screening and are publicly available. Overgo probes derived from expressed sequence tags (ESTs, representing 21 candidate genes for traits important for the mink industry, were used to screen the BAC library. These included candidate genes for coat coloring, hair growth and length, coarseness, and some receptors potentially involved in viral diseases in mink. The extensive screening yielded positive results for 19 of these genes. Thirty-five clones corresponding to 19 genes were sequenced using 454 Roche, and large contigs (184 kb in average were assembled. Knowing the complete sequences of these candidate genes will enable confirmation of the association with a phenotype and the finding of causative mutations for the targeted phenotypes. Additionally, 1577 BAC clones were end sequenced; 2505 BAC end sequences (80% of BACs were obtained. An excess of 2 Mb has been analyzed, thus giving a snapshot of the mink genome. Conclusions The availability of the CHORI-321 American mink BAC library will aid in identification of genes and genomic regions of interest. We have demonstrated how the library can be used to identify specific genes of interest, develop genetic markers, and for BAC end sequencing and deep sequencing of selected clones. To our knowledge, this is the

    Aleutian disease (AD) of mink most closely resembles systemic lupus erythematosus (SLE) in man; both are immune complex disease. In experimental AD serum immune complexes are determined by the /sup 125/J-C 1 q-binding test using human C 1 q. Mink (n = 12) infected intraperitoneally with Aleutian disease virus (ADV), grown in fetal mink kidney cells, developed during the course of infection a mean of /sup 125/I-C 1 q serum binding equivalent to 3.62 +- 1.68 mg./ml. aggr. HGG. (aggregated human immunoglobulin). Sera of mink (n = 8) which were infected with ADV grown in L-cells showed a less marked /sup 125/I-C 1 q binding with a mean equivalent to 2.52 +- 1.43 mg./ml. aggr. HGG. In contrast control animals (n = 8) treated with non-ADV-infected mink epidermal fibroblasts or Eagle's minimal essential medium substituted with fetal calf serum only bound /sup 125/I-C 1 q equivalent to 1.02 +- 0.99 mg./ml. aggr. HGG. In mink infected with ADV propagated in fetal mink kidney cells a constant increase in the /sup 125/I-C 1 q serum binding occurred from the 4th to the 7th and 13th week after ADV infection. Mink which were infected with ADV propagated in mouse L-cells exhibited a different pattern of the /sup 125/I-C 1 q serum binding capacity with a sharp increase from the 4th to the 7th week, followed by a decline towards the 13th week post infection. The serum /sup 125/I-C 1 q binding capacity of all experimental animal groups exhibited at different times of the experiment a significant correlation with the presence of hypergammaglobulinaemia and raised ADV-antibody titers. From the data obtained it appears that the /sup 125/I-C 1 q binding test, utilizing human C 1 q, is a suitable method for the detection of circulating serum immune complexes in mink during the course of ADV-infection.

    Full Text Available The effects of pregnancy on the Oral Mucosa Disorder (OMD have been sporadically documented in some developed countries. Less known is the status of OMD during pregnancy in less developed/developing countries. Iran is no exception. This study assesses the prevalence of OMD in 200 pregnant women and compares the findings with the findings from a 200 non-pregnant woman of similar age distribution in Iran. The participants had been referred to a clinic to receive reproductive age-related services. Participants suffering from systemic chronic diseases, those on medications/drugs, smokers, needing biopsies, and those with urgent Oral Mucosal Lesion (OML treatments were excluded from the study. Oral mucosal of all 400 participants were examined. The participants’ age ranges were from 17 to 47; with the average age of 33.14 for one group; and 30.23 for the other group. Both groups had the same level of formal education. Out of 400 examined women; 62 had lesions, including 47 pregnant (23.5%; and 15 non-pregnant (7.5% women. This result shows that the OMD rate of occurrence was significantly higher among the pregnant women. Higher OML prevalence in pregnant women, as compared to the non-pregnant women, indicates the importance of timely oral examination of pregnant women and subsequent treatment plans for them.

    Full Text Available This short story raises ethical issues about a woman’s request for medical assistance to get pregnant. In this fictional account, a 34-year-old woman has been trying to get pregnant for the last year. Her husband would like to keep trying for one more year, but the woman loses patience. She visits an ob-gyn and requests artificial insemination. She does not intend to tell her husband about this medical assistance. The doctor has helped single women, lesbian couples, and married couples with pregnancies, but he feels conflicted by this request. The doctor and the woman discuss their concerns and plans. Then they decide on a course of action. In a creative way, this story aims to bring to life ethical issues about assisted reproduction, complex relationships, individual choice, non- judgmental attitudes, deception, confidentiality, genetic connections, and social parents. But this story is not a textbook case that illustrates a clearly defined ethical issue. On the contrary, the story shows that some common ethical ideas don’t quite fit the characters’ experiences and the readers’ reactions.

    2015-01-01

    The optimal timing of separating the mink dam from the litter is suggested to be a balance between the partly conflicting needs of the mother and the kits. Early removal of the dam or partial removal of the litter may protect the dam against exhaustion. Little is known about the maternal motivation...... around the time of separation. Therefore, we investigated the effects of separating the dam from the litter, using brown first-parity dams (N=374) randomly assigned within each date of delivery to two treatment groups: The dam was taken away from the litter either at day 49 ±1 (7w, N=185) or at day 56 ±1...... (8w, N=189) after birth. The aim was to investigate whether the dams had a different motivation to take care of the litter after 7 and 8 weeks, estimated by non-invasive determination of cortisol (FCM: Faecal Corticsol Metabolites) and dam calls the first week after separation. The two treatment...

    and maternal motivation around the time of weaning and separation. Therefore, we investigated effects of separating the dam from the litter using brown first-parity farm mink dams (n = 374) taken away from the litter either day 49 ± 1 (7w, n = 185) or day 56 ± 1 (8w, n = 189) after birth. The aim...... was to investigate whether the dams experienced stress/had a different motivation to be reunited with the litter after7 and 8 weeks, estimated by non-invasive determination of cortisol (FCM: Faecal Cortisol Metabolites)and dam behaviour including calls the first week after separation (D0: Day of removal, D1: next.......024). We interpret these results as a higher maternal motivation in dams at 7 weeks than at 8 weeks after birth. Additionally, the separation-induced calling in dams decreased with increasing litter size (P = 0.022). Thus in addition to litter age, the size of the litter is important for the maternal...

  1. Expression of mink cell focus-forming murine leukemia virus-related transcripts in AKR mice

    1987-01-01

    The authors used a synthetic 16-base-pair mink cell focus-forming (MCF) env-specific oligomer as radiolabeled probe to study MCF murine leukemia virus (MuLV)-related transcripts in brain, kidney, liver, spleen, and thymus tissues of AKR mice ranging from 5 weeks to 6 months (mo) of age. Tissue-specific expression of poly(A) + RNAs was seen. In addition, all the tissues tested contained 3.0-kb messages. The transcription of these MCF-related mRNAs was independent of the presence of ecotropic and xenotropic MuLVs. In general, expression of the MCF env-related transcripts appeared to peak at 2 mo of age; these messages were barely detectable in brain, kidney, liver, and spleen tissues after 2 mo and in thymus tissue after 4 mo of age. All of the subgenomic MCF env-related mRNAs appeared to contain the 190-base-pair cellular DNA insert, characteristic of the long terminal repeats associated with endogenous MCF env-related proviruses. No genomic-size (8.4-kb) transcripts corresponding to endogenous MCF-related proviruses were detected. An 8.4-kb MCF env-related mRNA was first seen at 3 mo of age, exclusively in thymus tissue. This species most likely represents the first appearance of a recombinant MCF-related MuLV genome. The transcripts which were detected in thymus tissue might be involved in the generation of leukemogenic MCF viruses

    Virulent mink enteritis parvovirus (MEV) strain MEV-LHV replicated to higher titers in feline F81 cells than attenuated strain MEV-L. Phylogenetic and sequence analyses of the VP2 gene of MEV-LHV, MEV-L and other strains in GenBank revealed two evolutionary branches separating virulent and attenuated strains. Three residues, 101, 232 and 411, differed between virulent and attenuated strains but were conserved within the two branches. Site-directed mutagenesis of the VP2 gene of infectious plasmids of attenuated strain MEV-L respectively replacing residues 101 Ile and 411 Ala with Thr and Glu of virulent strains (MEV-L I101T and MEV-L A411E) increased replication efficiency but still to lower levels than MEV-LHV. However, viruses with mutation of residue 232 (MEV-L I232V and MEV-L I101T/I232V/A411E) decreased viral transcription and replication levels. The three VP2 residues 101, 232 and 411, located on or near the capsid surface, played different roles in the infection processes of MEV. Copyright © 2016 Elsevier B.V. All rights reserved.

    We investigated growth-related and sex-related morphological changes in the skulls of 144 North Pacific common minke whales Balaenoptera acutorostrata. Measurement was conducted at 39 points on the skull and mandible to extract individual allometric equations relating the length and zygomatic width of the skull. The results revealed no significant differences in skull morphology by sex except for width of occipital bone. The size relative to the skull of the anatomical parts involved in feeding, such as the rostrum and mandible, increased after birth. In contrast, the sensory organs and the anatomical regions involved in neurological function, such as the orbit, tympanic bullae, and foramen magnum, were fully developed at birth, and their relative size reduced over the course of development. This is the first study to investigate developmental changes in the skull morphology using more than 100 baleen whale specimens, and we believe the results of this study will contribute greatly to multiple areas of baleen whale research, including taxonomy and paleontology. © 2014 Wiley Periodicals, Inc.

    Full Text Available Introduction: Prolongation of QT interval might result in dangerous cardiac arrhythmias, including Torsades de Pointes (TdP, consequently leading to syncope or death. A limited number of studies carried out in this respect to date have shown that QT interval might increase during pregnancy. On the other hand, it has been shown that each pregnancy might result in an increase in the risk of cardiac accidents in patients with long QT interval. Therefore, the present study was undertaken to compare QT intervals in pregnant and non-pregnant women. Methods: Pregnant women group consisted of 40 women in the second and third trimesters of pregnancy and the non-pregnant control group consisted of healthy women 18-35 years of age. All the patients underwent standard 12-lead electrocardiogram (ECG. The QT interval was measured for each patient at lead II. The mean corrected QT interval (QTc and QT dispersions (QTd were compared between the two groups. Results: Mean heart rates in the pregnant and non-pregnant groups were 98.55±14.09 and 72.53±13.17 beats/minutes (P<0.001. QTd and QTc means were in the normal range in both groups; however, these variables were 49.50±12.80 and 43.03±18.47 milliseconds in the pregnant group and 39.5±9.59 and 40.38±17.20 milliseconds in the control group, respectively (P<0.001. Conclusion: The QT interval was longer in pregnant women compared to non-pregnant women; however, it was in the normal range in both groups. Therefore, it is important to monitor and manage risk factors involved in prolongation of QT interval and prevent concurrence of these factors with pregnancy.

    Glycogen synthesis by mink uterine glandular and luminal epithelia (GE and LE) is stimulated by estradiol (E 2 ) during estrus. Subsequently, the glycogen deposits are mobilized to near completion to meet the energy requirements of pre-embryonic development and implantation by as yet undetermined mechanisms. We hypothesized that progesterone (P 4 ) was responsible for catabolism of uterine glycogen reserves as one of its actions to ensure reproductive success. Mink were treated with E 2 , P 4 or vehicle (controls) for 3 days and uteri collected 24 h (E 2 , P 4 and vehicle) and 96 h (E 2 ) later. To evaluate E 2 priming, mink were treated with E 2 for 3 days, then P 4 for an additional 3 days (E 2 →P 4 ) and uteri collected 24 h later. Percent glycogen content of uterine epithelia was greater at E 2 + 96 h (GE = 5.71 ± 0.55; LE = 11.54 ± 2.32) than E 2 +24 h (GE = 3.63 ± 0.71; LE = 2.82 ± 1.03), and both were higher than controls (GE = 0.27 ± 0.15; LE = 0.54 ± 0.30; P glycogen content (GE = 0.61 ± 0.16; LE = 0.51 ± 0.13), to levels not different from controls, while concomitantly increasing catabolic enzyme (glycogen phosphorylase m and glucose-6-phosphatase) gene expression and amount of phospho-glycogen synthase protein (inactive) in uterine homogenates. Interestingly, E 2 →P 4 increased glycogen synthase 1 messenger RNA (mRNA) and hexokinase 1mRNA and protein. Our findings suggest to us that while E 2 promotes glycogen accumulation by the mink uterus during estrus and pregnancy, it is P 4 that induces uterine glycogen catabolism, releasing the glucose that is essential to support pre-embryonic survival and implantation. © 2016 Japanese Society of Animal Science.

    The present report clearly states that radiosensitivity is highest during intrauterine development and that the possibility of different types of effects depends on the state of pregnancy and on the dose. The decision whether an examination of the abdomen or pelvis of pregnant or potentiably pregnant women should be carried out is made clear that a delay of examinations due to dose reduction is only warranted if no danger to the patient and/or the unborn child is involved.

    Full Text Available Sedentary behavior has been associated with adverse health outcomes among pregnant women; however, few studies have characterized sedentary behavior patterns in this population. We described patterns of accelerometer-determined indicators of sedentary behavior among a national sample of US pregnant (n = 234 women and non-pregnant (n = 1146 women participating in the NHANES 2003-06 cycles. We included women with ≥4 days of accelerometer wear of ≥10 h/day. A count threshold of <100 cpm was used to describe sedentary behavior as: 1 total accumulated sedentary time by bout length categories; 2 accumulated sedentary time within discrete bout length categories; 3 mean, median, and usual bout length; and 4 and bout frequency. Both non-pregnant and pregnant women spent up to 60% of their accelerometer wear time in sedentary behavior depending on the minimum bout threshold applied. Sedentary time was higher among pregnant women compared to non-pregnant women when lower bout thresholds (i.e. 10 min or less were applied. The majority of total sedentary time was accumulated in bouts lasting <10 min. The women averaged less than two prolonged sedentary bouts (i.e., ≥30 min per day, which accounted for nearly 20% of total accumulated sedentary time. When applying a minimum threshold of at least 15 min, sedentary time increased across pregnancy trimesters, while sedentary time was similar across trimesters when using lower thresholds. These findings provide the first characterization of accelerometer-determined indicators of sedentary behavior in pregnant women. The minimum bout threshold applied influenced estimates of sedentary time and patterns sedentary time accumulation across pregnancy trimesters.

    Full Text Available I have been photographing my children, Eden and Emmanuelle since I got pregnant in 2003. I photograph as a mother, from a mother's point of view, showing the different aspects of motherhood as I see them; the beautiful and the ugly, the magic and the frustration, the extremes that live side by side when you are a mother. I try to photograph them all. Crying, sadness, anxiety, mourning the body I will never have again, the woman I will never be again. The strong physical connection to the children, erotic at times, something I found out many mothers experience but do not talk about much. With my images I try to sing a love song to my children, they are my inspiration. Their love, sadness, joy and neediness are for me the most meaningful moments of my life, the moments I want to photograph and preserve. Those images are taken from my life, they are very personal, they are about being a mother, being a child, the intensity of raising a child. This work is about the essence of being human.

    A polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) assay has been developed to detect and differentiate between canine parvovirus (CPV) and mink enteritis virus (MEV). Eight CPV and three MEV epidemic strains isolated from 28 pathological samples from dogs and minks suspected of being infected with parvovirus were amplified by PCR using a pair of specific primers designed based on the CPV-N strain (M19296). PCR amplified a fragment of 1016bp from the genomic DNA of both MEV and CPV. The MEV-derived fragment could be digested with the restriction enzyme BSP1407I into three fragments of 102bp, 312bp and 602bp, while the fragment amplified from the CPV genomic DNA was digested into only two fragments of 414bp and 602bp. The lowest DNA concentration of CPV and MEV that could be detected using this assay was 0.004μg/ml and 0.03μg/ml, respectively. The PCR-RFLP assay developed in the present study can, therefore, be used to detect and differentiate MEV from CPV with high specificity and sensitivity. Copyright © 2014 Elsevier B.V.

    Cetaceans possess highly derived auditory systems adapted for underwater hearing. Odontoceti (toothed whales) are thought to receive sound through specialized fat bodies that contact the tympanoperiotic complex, the bones housing the middle and inner ears. However, sound reception pathways remain unknown in Mysticeti (baleen whales), which have very different cranial anatomies compared to odontocetes. Here, we report a potential fatty sound reception pathway in the minke whale (Balaenoptera acutorostrata), a mysticete of the balaenopterid family. The cephalic anatomy of seven minke whales was investigated using computerized tomography and magnetic resonance imaging, verified through dissections. Findings include a large, well-formed fat body lateral, dorsal, and posterior to the mandibular ramus and lateral to the tympanoperiotic complex. This fat body inserts into the tympanoperiotic complex at the lateral aperture between the tympanic and periotic bones and is in contact with the ossicles. There is also a second, smaller body of fat found within the tympanic bone, which contacts the ossicles as well. This is the first analysis of these fatty tissues' association with the auditory structures in a mysticete, providing anatomical evidence that fatty sound reception pathways may not be a unique feature of odontocete cetaceans.

    Babesiosis is a tick-borne protozoan disease affecting many mammalian species worldwide, caused by the intraerythrocytic multiplication of Babesia spp. The present study aimed to detect the presence of Babesia sp. in 13 American mink from Hokkaido, Japan. One of 13 animals was positive, as indicated by nested PCR targeting the 18S ribosomal RNA (SSU rDNA) and subunit 7 (eta) of the chaperonin-containing t-complex polypeptide 1 (CCT7) genes from species of Babesia and Theileria. Sequencing of the PCR product of SSU rDNA revealed 99% homology to the isolates of Babesia sp. SAP#131 found in raccoons in Hokkaido, whereas that of the CCT7 gene showed 80% homology to the isolates of Babesia gibsoni in dogs as determined by BLAST analysis. We refer to the cognate sequence as Babesia sp. NV-1. Phylogenetic analyses of SSU rDNA and CCT7 genes from Babesia sp. NV-1 revealed them to be most closely related to the Babesia sp. SAP#131 from a raccoon in Hokkaido and to canine B. gibsoni, respectively. Here, we provide the first molecular evidence of the Babesia sp. NV-1 parasite in feral American mink ( Neovison vison ) in Hokkaido, Japan.

    The paper is devoted to the study of the activity of the important metabolizing mediators/modulators of the central nervous system: adenosine, angiotensin and GABA as well as specific bonding of 14 C-GABA by synaptic membranes of brain structures in minks who were in the 10-km zone of the Chernobyl NPP from 0.5 months to 3 years. Adenosine deaminase, angiotensin converting enzyme and glutamate decarboxylase activities endured significant changes in the hypothalamus, striatum, hippocampus, cerebellum, cerebral, cortex, medulla oblongata and midbrain of minks; the direction and the extent of manifestation of those changes depend on the term of animals' stay in the zone. The GABA reception in the cerebral cortex and medulla oblongata increased significantly and progressively with the prolongation of exposure to radiation. It is concluded that the variety of changes, their regional-specificity and dependence on exposure of animals to the radiation factors of the Chernobyl NPP 10-km zone may induce development of serious complications not only in nervous but in some other systems

    Fur quality in mink (Neovison vison) is a composite trait, consisting of e.g. guard hair length, guard hair thickness and density of wool. A genome wide QTL search was performed to detect QTL for fur quality traits in mink. Here we present the results of QTL analyses for guard hair length, guard...... hair thickness and density of wool. Data from an F2-cross was analysed across fourteen chromosomes using 100 microsatellites as markers with a spacing of approximately 20 cM. The two lines used for the F2-cross were Nordic wild mink and American short nap mink. In total 1,083 animals (21 wild type, 25...... short nap, 103 F1 and 934 F2) were marker typed and recorded for the three presented fur quality traits. For the QTL-analyses a regression analysis implemented in QTL Express software was used. Evidence was found for the existence of QTL for guard hair length, guard hair thickness and density of wool...

    With more women entering surgical training, it will become more commonplace to encounter pregnant surgeons. This paper discusses the evidence for work-related risk factors as well as outlining the rights of a pregnant doctor. There are, in fact, very few real risks to pregnancy encountered as a surgeon, with the main risks involving standing or sitting for long periods and fatigue, which can be managed with support from the department. It is important for women in surgery to know that it is possible to continue their training while pregnant so they do not feel pressured into changing to a less demanding specialty or even leaving medicine entirely. It is also important for other professionals to understand the risks and choices faced by pregnant surgeons so that they can better support them in the workplace.

    We assessed the safety and efficacy of an experimental canarypox-vectored recombinant canine distemper virus (CDV) subunit vaccine in the Siberian polecat (Mustela eversmanni), a close relative of the black-footed ferret, (M. nigripes), an endangered species that is highly susceptible to the virus. Siberian polecats were randomized into six treatment groups. Recombinant canine distemper vaccine was administered s.c. at three dose levels (104.5, 105.0, and 105.5 plaque-forming units [PFU] per dose) and was administered orally by spraying the vaccine into the oropharnyx at two dose levels (105.5, 108.0 PFU per dose). The sixth group of control animals was not vaccinated. For both routes of administration, two 1-ml doses of reconstituted vaccine were delivered 4 wk apart, followed by live virus challenge 3 wk after the second vaccination. During the challenge, Synder Hill test strain CDV obtained from the National Veterinary Services Laboratory in Ames, Iowa, was administered i.p. Serial blood samples for CDV serology were collected immediately before vaccination and challenge, and 10, 15, and 20 days after challenge. Clinical signs and body weights were recorded up to 32 days after challenge. The survival rate in animals receiving vaccine at the highest oral dose (108.0 PFU per dose) was 83.3%. Survival rate was 50.0% in the high s.c. and 60.0% in the medium s.c. groups. All animals in the low–s.c. dose, low–oral dose, and control groups died after exposure. Vaccine dose overall (oral and s.c.) and dose in response to s.c. administration when considered alone were significant predictors of survival (P = 0.006 and P = 0.04, respectively). Among the polecats challenged with virulent virus, those that died became sick sooner than those that survived. Animals that died lost significantly more weight during the 10 days after challenge than did animals that survived (P = 0.02). Survival rates did not differ by sex, founder female status, or breeding pedigree in any of

    The capsid proteins of the ADV-G isolate of Aleutian mink disease parvovirus (ADV) were expressed in 10 nonoverlapping segments as fusions with maltose-binding protein in pMAL-C2 (pVP1, pVP2a through pVP2i). The constructs were designed to capture the VP1 unique sequence and the portions analogous to the four variable surface loops of canine parvovirus (CPV) in individual fragments (pVP2b, pVP2d, pVP2e, and pVP2g, respectively). The panel of fusion proteins was immunoblotted with sera from mink infected with ADV. Seropositive mink infected with either ADV-TR, ADV-Utah, or ADV-Pullman reacted preferentially against certain segments, regardless of mink genotype or virus inoculum. The most consistently immunoreactive regions were pVP2g, pVP2e, and pVP2f, the segments that encompassed the analogs of CPV surface loops 3 and 4. The VP1 unique region was also consistently immunoreactive. These findings indicated that infected mink recognize linear epitopes that localized to certain regions of the capsid protein sequence. The segment containing the hypervariable region (pVP2d), corresponding to CPV loop 2, was also expressed from ADV-Utah. An anti-ADV-G monoclonal antibody and a rabbit anti-ADV-G capsid antibody reacted exclusively with the ADV-G pVP2d segment but not with the corresponding segment from ADV-Utah. Mink infected with ADV-TR or ADV-Utah also preferentially reacted with the pVP2d sequence characteristic of that virus. These results suggested that the loop 2 region may contain a type-specific linear epitope and that the epitope may also be specifically recognized by infected mink. Heterologous antisera were prepared against the VP1 unique region and the four segments capturing the variable surface loops of CPV. The antisera against the proteins containing loop 3 or loop 4, as well as the anticapsid antibody, neutralized ADV-G infectivity in vitro and bound to capsids in immune electron microscopy. These results suggested that regions of the ADV capsid proteins

    Full Text Available A vaccine is a formulation of biological origin that contains substances capable of inducing immune processes without the ability to cause a disease. Vaccination is considered the best mean to prevent infectious diseases and their serious complications. Vaccination of a pregnant women can provide protection against severe infectious diseases of both pregnant women and their children. The aim of the study is to present currently available types of vaccines recommended for pregnant women and indications for their use by analyzing the data available in the PubMed, and Medline electronic databases. In the United States, vaccination recommendations for pregnant women include inactivated influenza vaccine and tetanus and diphtheria toxoid vaccine (Tdap. In some countries, pregnant women also receive a vaccine against hepatitis B as well as anti hepatitis A and E. There are also studies on vaccines against the RSV virus and pneumococci. Vaccination is the most effective form of prevention of infectious diseases and their use during pregnancy does not entail any additional risk to the mother or her baby. The benefits of vaccination are huge, so pregnant women should take  recommended vaccination and shouldn’t  be afraid of using them.

    A study was carried out at the Adolescent Unit of The Montreal Children's Hospital from September 1970 to December 1972, the focus of which evolved from the pregnant teenager in general to the short- and long-term effects of her abortion. Answers to a questionnaire administered to 65 pregnant girls to determine the psychosocial characteristics of the pregnant teenager indicated that these girls are not socially or emotionally abnormal. A follow-up study of 50 girls who had an abortion determined that the girls do not change their life styles or become emotionally unstable up to one year post-abortion, although most have a mild, normal reaction to the crisis. During the study period the clinic services evolved from mainly prenatal care to mainly abortion counselling, and then to providing the abortion with less counselling, placing emphasis on those cases which require other than medical services.

    Reasoning well about risk is most challenging when a woman is pregnant, for patient and doctor alike. During pregnancy, we tend to note the risks of medical interventions without adequately noting those of failing to intervene, yet when it's time to give birth, interventions are seldom questioned, even when they don't work. Meanwhile, outside the clinic, advice given to pregnant women on how to stay healthy in everyday life can seem capricious and overly cautious. This kind of reasoning reflects fear, not evidence.

    In order to distinguish true positive results in counterimmunoelectrophoresis from false positive ones an additive counterimmunoelectrophoresis was developed. The method was tested on selected mink serum samples as part of a routine testing for antibodies towards Aleutian disease virus on 3 million...... blood samples. The procedure of the method is, that a known positive serum sample is mixed with the patient serum to be tested. The result from a false positive sample will be one precipitin line towards virus and one nonspecific line. If the serum sample is a true positive one, the antibodies...... originating from the patient serum will be added to the antibodies in the standard positive serum giving only one precipitin line. The system is further extended by testing the serum samples towards an antigen preparation containing all the cellular components but free from virus....

    Full Text Available We attempted to settle the potential problems of bias caused by too soft earplugs and poor formation of the growth layers in age readings of common minke whales. Thus, we examined the feasibility of a new technique of incorporating gelatin in order to collect earplugs for age assessment. Frozen sectioning and histology of the earplug core were also used as methods to improve age estimation. Earplugs were collected by filling the space in the external auditory meatus with gelatin, hardening the gelatin, earplug and its fragments, by spraying with cooling gas, and removing the earplug embedded in gelatin. In 174 trials with common minke whales in the Western North Pacific of coastal waters of Japan in 2007–2009, it was revealed that embedding earplugs with gelatin minimized breakage and protected the neonatal line (NL. This method was particularly effective in younger animals. As a result, the readability was improved. We also examined the histological sections, which were sliced using the Kawamoto specialized frozen sectioning technique, and stained them separately with toluidine blue, haematoxylin and eosin, Sudan III, Sudan VII, and alizarin red S to display a clearer core surface image of the growth layers. The histological sections stained with alizarin red S provided the clearest images, in which we could easily identify both dark and pale laminations. This suggested a close relationship with the seasonal changes in calcium intake from feeding. Earlier age estimation methods focused on fat content in the growth layers; however, we found potential for an improvement in the readability of unclear growth layers when focusing on calcium.

    Pregnancy in rabbits alters the reactivity of the tissues to the virus of infectious myxomatosis. The livers of pregnant animals with the myxoma have a central acidophilic necrosis. Secondary lesions in the lungs are much more numerous and larger in the pregnant than in the non-gravid animals. In like manner the lesions in the spleen are more extensive in the pregnant rabbit. On the other hand the skin lesions of the pregnant animal are decreased in size. PMID:19870088

  20. Thermal adaptation of the crucian carp (Carassius carassius) cardiac delayed rectifier current, IKs, by homomeric assembly of Kv7.1 subunits without MinK.

    Ectothermic vertebrates experience acute and chronic temperature changes which affect cardiac excitability and may threaten electrical stability of the heart. Nevertheless, ectothermic hearts function over wide range of temperatures without cardiac arrhythmias, probably due to special molecular adaptations. We examine function and molecular basis of the slow delayed rectifier K(+) current (I(Ks)) in cardiac myocytes of a eurythermic fish (Carassius carassius L.). I(Ks) is an important repolarizing current that prevents excessive prolongation of cardiac action potential, but it is extremely slowly activating when expressed in typical molecular composition of the endothermic animals. Comparison of the I(Ks) of the crucian carp atrial myocytes with the currents produced by homomeric K(v)7.1 and heteromeric K(v)7.1/MinK channels in Chinese hamster ovary cells indicates that activation kinetics and pharmacological properties of the I(Ks) are similar to those of the homomeric K(v)7.1 channels. Consistently with electrophysiological properties and homomeric K(v)7.1 channel composition, atrial transcript expression of the MinK subunit is only 1.6-1.9% of the expression level of the K(v)7.1 subunit. Since activation kinetics of the homomeric K(v)7.1 channels is much faster than activation of the heteromeric K(v)7.1/MinK channels, the homomeric K(v)7.1 composition of the crucian carp cardiac I(Ks) is thermally adaptive: the slow delayed rectifier channels can open despite low body temperatures and curtail the duration of cardiac action potential in ectothermic crucian carp. We suggest that the homomeric K(v)7.1 channel assembly is an evolutionary thermal adaptation of ectothermic hearts and the heteromeric K(v)7.1/MinK channels evolved later to adapt I(Ks) to high body temperature of endotherms.

  1. A probabilistic risk assessment of the effects of methylmercury and PCBs on mink and kingfishers along East Fork Poplar Creek, Oak Ridge, Tennessee, USA

    Over fifty years of operations, storage, and disposal of wastes from the US Department of Energy (US DOE) Y-12 nuclear weapons facility at Oak Ridge, Tennessee, USA, has resulted in the contamination of water, sediment, biota, and floodplain soils of East Fork Poplar Creek. A preliminary assessment revealed that methylmercury and polychlorinated biphenyls (PCBs) were the contaminants of most concern. Because these contaminants are persistent, accumulate in tissues, and biomagnify up the food chain, piscivorous wildlife are the biota at greatest risk of exposure. The objective of this study was to estimate the risks posed by methylmercury and PCBs to two piscivorous species: mink and belted kingfishers. The authors conducted Monte Carlo simulations to estimate total daily intakes of each contaminant by each species and then integrated the resulting distributions with their respective dose-response curves to estimate risks. The results indicate that methylmercury poses a moderate risk to female mink (24% probability of at least 15% mortality) and kingfishers (50% probability of at least a 12--28% decline in fecundity depending on location). The PCBs pose a very serious risk to mink (52% probability of at least a 50% decline in reproductive fecundity), a species known to be especially sensitive to the effects of organochlorine substances, but little risk to kingfishers (<5% probability of a decline in reproductive fecundity greater than 10% at any location).

    A virus isolated from mink showing clinical signs of enteritis was identified as a high virulent mink enteritis parvovirus (MEV) based on its biological characteristics in vivo and in vitro. Mink, challenged with this strain named MEV-LHV, exhibited severe pathological lesions as compared to those challenged with attenuated strain MEV-L. MEV-LHV also showed higher infection and replication efficiencies in vitro than MEV-L. Sequence of the complete genome of MEV-LHV was determined and analyzed in comparison with those in GenBank, which revealed that MEV-LHV shared high homology with virulent strain MEV SD12/01, whereas MEV-L was closely related to Abashiri and vaccine strain MEVB, and belonged to a different branch of the phylogenetic tree. The genomes of the two strains differed by insertions and deletions in their palindromic termini and specific unique mutations (especially VP2 300) in coding sequences which may be involved in viral replication and pathogenicity. The results of this study provide a better understanding of the biological and genomic characteristics of MEV and identify certain regions and sites that may be involved in viral replication and pathogenicity.

Many medical students decide against surgery as a profession due to the long work hours and family strain. The pregnant female surgical resident has an added stress factor compared to her male counterpart. Methods: We distributed an electronic, online 26-question survey to 32 general surgery programs in the southwestern region of the United States. Each program distributed our survey to the female surgical residents who had been pregnant during residency in the last 5 years. Each program was re-contacted 6 weeks after the initial contact. Most questions were in a 5-point Likert scale format. The responses were collected and analyzed using the Survey Monkey website. Results: An unvalidated survey was sent to 32 general surgery programs and 26 programs responded (81%. Each program was asked for the total number of possible responses from female residents that met our criteria (60 female residents. Seven of the programs (27% stated that they have had zero residents pregnant. We had 22 residents respond (37%. Over half of the residents (55% were pregnant during their 2nd or 3rd year of residency, with only 18% pregnant during a research year. Thirty-one percent had a lower American Board of Surgery In-Training Exam (ABSITE score. Ninety percent of the residents were able to take 4 weeks or more for maternity leave. Most of the residents (95% stated that they would do this again during residency given the opportunity, but many of the residents felt that returning back to work

    Domestic violence during pregnancy is an important social & health issue in all societies. In Muslim world and particularly underdeveloped countries, domestic violence is often under reported. It is the need of hour to encourage reporting of such events & implementation of research-based policies for prevention of women abuse & support of the victims of domestic violence (DV). The objective of this study was to highlight this neglected social problem of our society & to identify at risk population. This is a cross sectional study conducted at Ayub Teaching Hospital & Benazir Bhutto Shaheed Teaching Hospital, Abbottabad (January 2014 to December. 2016). Pregnant women were inquired regarding history of abuse by husband and sociodemographic characteristics were noted in a Performa to analyse the risk factors for domestic violence. The overall prevalence was found to be 35%. Out of 1000 pregnant women, 270 (27%) suffered from simple violence and 60 (6%) were victims of grievous assault. Violence among pregnant women is found to be more prevalent among residents of urban areas, women of older age being uneducated & belonging to poor socioeconomic status. Domestic violence during pregnancy is a common & often neglected psychosocial health problem. High risk population needs to be identified so that preventive strategies can be planned & implemented.

    We investigated the effects of nest box climate on early mink kit mortality and growth. We hypothesised that litters in warm nest boxes experience less hypothermia-induced mortality and higher growth rates during the 1st week of life. This study included data from 749, 1-year-old breeding dams with access to nesting materials. Kits were weighed on days 1 and 7, dead kits were collected daily from birth until day 7 after birth, and nest climate was measured continuously from days 1 to 6. We tested the influences of the following daily temperature (T) and humidity (H) parameters on the number of live-born kit deaths and kit growth: T mean, T min, T max, T var (fluctuation) and H mean. The nest microclimate experienced by the kits was buffered against the ambient climate, with higher temperatures and reduced climate fluctuation. Most (77.0%) live-born kit deaths in the 1st week occurred on days 0 and 1. Seven of 15 climate parameters on days 1 to 3 had significant effects on live-born kit mortality. However, conflicting effects among days, marginal effects and late effects indicated that climate was not the primary cause of kit mortality. Five of 30 climate parameters had significant effects on kit growth. Few and conflicting effects indicated that the climate effect on growth was negligible. One exception was that large nest temperature fluctuations on day 1 were associated with reduced deaths of live-born kit (P<0.001) and increased kit growth (P=0.003). Litter size affected kit vitality; larger total litter size at birth was associated with greater risks of kit death (P<0.001) and reduced growth (P<0.001). The number of living kits in litters had the opposite effect, as kits in large liveborn litters had a reduced risk of death (P<0.001) and those with large mean litter size on days 1 to 7 had increased growth (P=0.026). Nest box temperature had little effect on early kit survival and growth, which could be due to dams' additional maternal behaviour. Therefore, we

Qualitative and descriptive study conducted from February to November 2013 at a Primary Care Unit in Fortaleza, Ceará, Brazil, through focus groups with 16 adolescents from the group of pregnant women in the second or third trimester of pregnancy. The analysis identified central ideas and units of meanings that formed the categories. The strategy of a group of pregnant teenagers, which provides a space for coexistence and the establishment of ties encourages these individuals to talk about their needs, re-signifying their ties. Educational strategies to promote self-care of pregnant teenagers and care for their babies involve the sharing of experiences, doubts and beliefs. Considerations and suggestions of the adolescents contributed to guide nurses' practice and provide a strategic space of care and support for pregnant adolescents in primary care.

    The structure of the olfactory apparatus is not well known in both archaic and extant whales; the result of poor preservation in most fossils and locational isolation deep within the skulls in both fossil and Recent taxa. Several specimens now shed additional light on the subject. A partial skull of an archaic cetacean is reported from the Pamunkey River, Virginia, USA. The specimen probably derives from the upper middle Eocene (Piney Point Formation) and is tentatively assigned to the Protocetidae. Uncrushed cranial cavities associated with the olfactory apparatus were devoid of sediment. CT scans clearly reveal the dorsal nasal meatus, ethmoturbinates within the olfactory recess, the cribriform plate, the area occupied by the olfactory bulbs, and the olfactory nerve tract. Several sectioned skulls of the minke whale (Balaenoptera acutorostrata) were also examined, and olfactory structures are remarkably similar to those observed in the fossil skull from the Pamunkey River. One important difference between the two is that the fossil specimen has an elongate olfactory nerve tract. The more forward position of the external nares in extant balaenopterids when compared with those of extant odontocetes is interpreted to be the result of the need to retain a functional olfactory apparatus and the forward position of the supraoccipital/cranial vertex. An increase in the distance between the occipital condyles and the vertex in balaenopterids enhances the mechanical advantage of the epaxial musculature that inserts on the occiput, a specialization that likely stabilizes the head of these enormous mammals during lunge feeding.

    The optimal timing of separating the mink dam from the litter is suggested to be a balance between the partly conflicting needs of the mother and the kits. Early removal of the dam or partial removal of the litter may protect the dam against exhaustion. Little is known about the maternal motivation...... around the time of separation. Therefore, we investigated the effects of separating the dam from the litter, using brown first-parity dams (N=374) randomly assigned within each date of delivery to two treatment groups: The dam was taken away from the litter either at day 49 ±1 (7w, N=185) or at day 56 ±1......

    We aimed to find a prevalence of human papilloma virus (HPV) in order to define the 100 genotypes and subset of 14 oncogenic genotypes in pregnant Turkish women and to compare these with non-pregnant women. Cervical thin-prep specimens were obtained from 164 women in the first trimester pregnancy and 153 non pregnant women. 29.2% of pregnant versus 19.6% of non-pregnant Turkish women had at least one of the 100 types of HPV infection--a statistically significant difference. The rate of 14 high-risk HPV genotype infections was significantly higher in pregnant (14.6) compared to non-pregnant Turkish women (9.6%). Pregnant Turkish women are at higher risk for all HPV infections including high-risk cervical cancer genotypes.

The diet and insulin have revolutionized the care related with pregnancy complicated by diabetes mellitus. To report the management experience in patients with diabetes and pregnancy at the Instituto Materno Infantil, Estado de Mexico. A descriptive, retrospective, observational and cross-sectional study of pregnant women with diabetes and pregnancy was conducted from 2003 to 2004. We included 55 pregnant women who had: gestational diabetes 30 (54.4%), pregestational diabetes 24 (43.6%), and carbohydrate intolerance 1 (1.8%); every one of them were controlled either with diet, insulin or both. The mean age was 30.6, 80% with family history of type 2 diabetes mellitus, 9% gestational diabetes. Gestational diabetes was diagnosed in 33.3% by abnormal 50 g glucose screening and 46.6% with oral glucose tolerance test (OGTT). The main complications among the patients were urinary disease (61.3%) and the major fetal malformation were those related with cardiovascular disease (9.09%). The most frequent mode of delivery was cesarean section (58%) and birth weight was of 3,146 g. The main risk factors identified among women in the study group were as follow: More than 25 years of age and family history of diabetes mellitus. We observed a progressive increase in the insulin dosage. The most consistent complications among the patients were urinary infection and the major fetal malformation was cardiovascular disease.

    A group of mink cell focus-forming (MCF) viruses was derived by inoculation of NFS/N mice with Moloney murine leukemia virus (Mo-MuLV 1387) and was compared to a similarly derived group of MCF viruses from mice inoculated with Friend MuLV (Fr-MuLV 57). Antigenic analyses using monoclonal antibodies specific for MCF virus and xenotropic MuLV envelope proteins and genomic structural analyses by RNase T1-resistant oligonucleotide finger-printing indicated that the Moloney and Friend MCF viruses arose by recombination of the respective ecotropic MuLVs with different endogenous retrovirus sequences of NFS mice.

    The c-Jun- N -terminal kinase (JNK) signaling pathway regulates nervous system development, axon regeneration, and neuronal degeneration after acute injury or in chronic neurodegenerative disease. Dual leucine zipper kinase (DLK) is required for stress-induced JNK signaling in neurons, yet the factors that initiate DLK/JNK pathway activity remain poorly defined. In the present study, we identify the Ste20 kinases MAP4K4, misshapen-like kinase 1 (MINK1 or MAP4K6) and TNIK Traf2- and Nck-interacting kinase (TNIK or MAP4K7), as upstream regulators of DLK/JNK signaling in neurons. Using a trophic factor withdrawal-based model of neurodegeneration in both male and female embryonic mouse dorsal root ganglion neurons, we show that MAP4K4, MINK1, and TNIK act redundantly to regulate DLK activation and downstream JNK-dependent phosphorylation of c-Jun in response to stress. Targeting MAP4K4, MINK1, and TNIK, but not any of these kinases individually, is sufficient to protect neurons potently from degeneration. Pharmacological inhibition of MAP4Ks blocks stabilization and phosphorylation of DLK within axons and subsequent retrograde translocation of the JNK signaling complex to the nucleus. These results position MAP4Ks as important regulators of the DLK/JNK signaling pathway. SIGNIFICANCE STATEMENT Neuronal degeneration occurs in disparate circumstances: during development to refine neuronal connections, after injury to clear damaged neurons, or pathologically during disease. The dual leucine zipper kinase (DLK)/c-Jun- N -terminal kinase (JNK) pathway represents a conserved regulator of neuronal injury signaling that drives both neurodegeneration and axon regeneration, yet little is known about the factors that initiate DLK activity. Here, we uncover a novel role for a subfamily of MAP4 kinases consisting of MAP4K4, Traf2- and Nck-interacting kinase (TNIK or MAP4K7), and misshapen-like kinase 1 (MINK1 or MAP4K6) in regulating DLK/JNK signaling in neurons.

    To determine the smoking behavior in pregnant Arab American women who attended a Women, Infant and Children (WIC) program at a local county public health clinic and compare the incidence of smoking behaviors of pregnant Arab American women with pregnant women who were not Arab Americans. Data were extracted from a computer database that contained information from health history charts of pregnant Arab and non-Arab American women. The study sample was 830 women, 823 of whom were Arab American participants enrolled in the WIC program in Michigan. Approximately 6% of pregnant Arab Americans smoked during pregnancy. The prevalence of smoking behavior among pregnant Arab American women was similar to that of smoking behaviors of Hispanics and Asian Americans in the United States. Although smoking behavior is a serious problem among Arab American immigrants in general and in the Arab world in particular, cultural factors that support healthy behavior during pregnancy in the Arab culture seem to limit the use of tobacco in pregnant women. Nurses who care for Arab American pregnant women can use this information to better inform their care of these patients.

    Highlights: ► We investigate the exposure of pregnant and non-pregnant mice to cadmium (Cd) on lead (Pb) contaminated soil. ► We examine the changes in lead accumulation in mice due to the presence of cadmium in soil. ► Lead accumulation is higher in pregnant compared to non-pregnant mice. ► Cadmium decreases lead accumulation in all mice irrespective of status. - Abstract: People are frequently exposed to combinations of contaminants but there is a paucity of data on the effects of mixed contaminants at low doses. This study investigated the influence of cadmium (Cd) on lead (Pb) accumulation in pregnant and non-pregnant mice following exposure to contaminated soil. Exposure to Pb from contaminated soils increased Pb accumulation in both pregnant and non-pregnant mice compared to unexposed control animals (pregnant and non-pregnant). Lead accumulation in the liver and kidneys of exposure pregnant mice (40 ± 15 mg Pb kg −1 ) was significantly higher (P −1 ). The presence of Cd in contaminated soil had a major effect on the Pb and Fe accumulation in the kidneys and liver, respectively. This study shows that Pb uptake is mediated by the presence of Cd in the co-contaminated soil and demonstrates that further research is required to investigate the influence of co-contaminants on human exposure at sub-chronic concentrations.

  5. Spatial and temporal analysis of second-generation anticoagulant rodenticide residues in polecats (Mustela putorius) from throughout their range in Britain, 1992-1999

    There is no evidence that extent of exposure of polecats to second-generation anticoagulant rodenticides has changed in Britain during the 1990s nor is it higher in recently recolonised areas in England where usage is higher. - Polecats (Mustela putorius) in Britain are currently expanding their range eastwards from Wales to reoccupy central and eastern areas of England. Second-generation anticoagulant rodenticides (SGARs), to which polecats are exposed by eating contaminated prey, are used more extensively in these central and eastern regions, leading to fears of increased exposure, and possible resultant mortality. We measured bromadiolone, difenacoum, flocoumafen and brodifacoum concentrations in the livers of 50 polecats from areas that included newly recolonised habitats and found that at least one SGAR was detected in the livers of 13 out of 37 (35.1%) male and 5 out of 13 (38.5%) female polecats. Difenacoum and bromadiolone were detected most frequently. We then combined these data with measurements on another 50 individuals from earlier studies to create a dataset for 100 polecats collected throughout the 1990s from across the whole of their current range. Using this dataset, we determined if there was any evidence that contamination in polecats had increased during the 1990s and whether animals from England were more contaminated than those from Wales, as might be expected given regional differences in the patterns of SGAR use. Overall, 31 of the 100 polecats analysed to date contained SGAR residues. The incidence was a little higher (40%) in animals that died between January and June and this probably better reflects the overall proportion of animals that are sub-lethally exposed. There was no statistically significant change during the 1990s in the proportion of polecats exposed to SGARs nor any evidence that greater use of SGARs in England resulted in more contamination of polecats. Contrary to expectation, the proportion of animals that contained

    Hepatic lipidosis is a common pathological finding in the American mink (Neovison vison) and can be caused by nutritional imbalance due to obesity or rapid body weight loss. The objectives of the present study were to investigate the timeline and characterize the development of hepatic lipidosis in mink in response to 0-7 days of food deprivation and liver recovery after 28 days of re-feeding. We report here the effects on hematological and endocrine variables, body fat mobilization, the development of hepatic lipidosis and the alterations in the liver lipid classes and tissue fatty acid (FA) sums. Food deprivation resulted in the rapid mobilization of body fat, most notably visceral, causing elevated hepatosomatic index and increased liver triacylglycerol content. The increased absolute amounts of liver total phospholipids and phosphatidylcholine suggested endoplasmic reticulum stress. The hepatic lipid infiltration and the altered liver lipid profiles were associated with a significantly reduced proportion of n-3 polyunsaturated FA (PUFA) in the livers and the decrease was more evident in the females. Likewise, re-feeding of the female mink resulted in a more pronounced recovery of the liver n-3 PUFA. The rapid decrease in the n-3/n-6 PUFA ratio in response to food deprivation could trigger an inflammatory response in the liver. This could be a key contributor to the pathophysiology of fatty liver disease in mink influencing disease progression.

    We examined the effects of a guided imagery intervention on perceived stress in pregnant adolescents. Thirty-five pregnant adolescents recruited from a local alternative education program participated in a guided imagery intervention. Participants listened to a pregnancy-specific guided imagery recording on four separate occasions during their pregnancies. Perceived stress was measured immediately before and after each session using the Perceived Stress Measure-9 (PSM-9). Participants' pre- and postsession PSM-9 scores for three of the four sessions demonstrated a significant reduction in stress. Participants' baseline stress levels also decreased significantly across the four listening sessions. The greatest reductions in stress within and between sessions occurred in the early sessions, with effects diminishing over time. Pregnant teens experienced initial short- and long-term stress reduction during a guided imagery intervention, supporting the use of guided imagery to reduce stress in pregnant adolescents.

    2015-04-01

    Full Text Available Properly selected and prescribed physical activity during pregnancy has a favorable effects on the health of pregnant women and the fetus, and is excellent preparation for childbirth. Absolute and relative contraindications to exercise during pregnancy are well defined, as well as the warning signs to terminate exercise while pregnant. Knowledge of these is essential for physically active pregnant women and exercise professionals that work with pregnant women. Pregnant women should be moderately physically active every day of the week for at least 30 minutes. The term moderate is thoroughly and clearly defined in the guidelines. Resistance exercises during pregnancy are safe but it is advised to use light loads and a large number of repetitions (e.g. 15-20 repetitions. Strength exercises for the pelvic floor muscles deserves a special place during pregnancy. Appropriate forms of physical activity for pregnant women are walking and jogging, swimming and aquatic exercise, cycling, Pilates and yoga, aerobics, fitness and cross-country skiing. Certain forms of physical activity need special adjustments (alpine skiing, ice skating and rollerblading, racket sports, team ball games, horseback riding and scuba diving.

    2008-01-01

    The aim of this study was to assess the awareness of dentists in Riyadh city about treatment alternatives available for pregnant patients. A self-administered questionnaire was distributed among 500 dentists practicing in Riyadh city. The questionnaire included data on dentists socio-demographic and practice characteristics in addition to management choices of the pregnant dental patient such as dental treatment practices and selected therapeutic choices. Out of the questionnaires distributed, 212 questionnaires were collected (42.5% response rate). Most of the participants were general practitioners, with less than 5 years clinical experience, who obtained their degree from local institutes and practiced in the government sectors. Over half of the participants stated that they would radiograph a pregnant patient who was suffering from pain from a tooth with doubtful diagnosis or would extract a non-restorable painful tooth. Two-thirds of the participating dentists would not replace a missing molar with a fixed partial denture during pregnancy. The majority of the participants (86%) would give oral hygiene instructions, prescribe a mouthwash and do scaling and/or root planing for a pregnant patient with gingival bleeding and calculus deposits. In respect to antibiotics, the majority of the dentists (96%) would prescribe amoxicillin to a pregnant patient. Of the four analgesic agents surveyed, paracetamol was the most popular analgesic agent (96.7%). On the use of local anesthetics, the majority of the dentists (75%) would use lidocaine without vasoconstrictor and would not use prilocaine with felypressin vasoconstrictor. The study showed that there was a lack of knowledge about the clinical management of the pregnant dental patients among the surveyed dentists regardless of their socio-demographic and practice characteristics necessitating continuous dental education programs on the dental management of pregnant dental patients.

    Pregnancy is a crisis in the human life cycle as an important turning point in aspects of anatomical, physiological and psychosocial changes. An unhappy pregnanus could influence the fetal growth and development and sense of maternal competence as well as bonding with the fetus which profoundly affect the nurture of the infant after delivery. The authors'purposes were to study happiness and related factors in pregnant women having antenatal care at King Chulalongkorn Memorial Hospital. Four hundred and thirty-eight pregnant women from the antenatal clinic at King Chulalongkorn Memorial Hospital were randomly selected to complete a set of questionnaires that consisted of personal information, pregnant information, The Oxford Happiness Questionnaire (OHQ), The Maudsley Personality Inventory (MPI) and The Marital Satisfaction Scale (MSS). Prevalence of happiness level was classified by descriptive analysis. Unpaired t-test, ANOVA and Pearson's Product Moment Correlation analyzed related factors to happiness in pregnant woman. Also Stepwise Multiple Regression Analysis was used to define predictive factors for happiness in pregnant women. The sample had a high level of happiness of 57.3%. Significant related factors to happiness were age between 31-35 years, high education level, high individual and family income, having saving deposition, no drug abuse, improved marital relationship, no conflict with relatives, extrovert and stable personality types and no concerns about post-partum body image. Four predictive factors for happiness in pregnant women were extrovert personality, stable personality, high family income and improved marital relationship. Level of happiness in pregnant women could be predicted by type of personality, family income and marital relationship.

    To compare the prevalence of malaria parasitaemia and the mean parasite density in pregnant women at first antenatal visit with those of the control subjects at Nnamdi Azikiwe University Teaching Hospital, Nnewi. A case control prospective survey using a structured questionnaire to collect data from pregnant women attending antenatal clinic between 1 April and 30 September 2001 and matched controls at the GOPD during the same period. Peripheral blood smears were examined in 420 pregnant women at their first antenatal visit and 200 control subjects to compare the prevalence of malaria parasitaemia and mean parasite density in pregnant women and controls. The prevalence of parasitaemia was 79.3 percent (i.e. 333 of 420) for pregnant women and 31.5 percent (or 63 of 200) for the control. For both pregnant women and controls, an overall prevalence of 63.1 percent was observed. The study found the mean parasite density for the pregnant women to be 1978 +/- 1531 (Mean +/- SD), while that of the controls was 766 +/- 1923. This study demonstrates the higher prevalence of malaria parasitaemia and mean parasite density in pregnant women when compared with the matched controls.

    Using an indirect immunofluorescence technique, the distribution of viral antigen in various tissues and blood mononuclear leukocytes was studied in wild mink, either vaccinated with an attenuated vaccine strain of canine distemper virus (CDV) or experimentally inoculated with the virulent Snyder-Hill strain of CDV. Viral antigen was detected in cells of the lymphoid system 6 to 12 days after vaccination. From 2 to 3 days after inoculation with the virulent strain, CDV antigen was demonstrated in cells of the lymphoid system and, during the incubation period, the antigen had spread to the epithelia and brain at days 6 and 12, respectively. In clinical cases of acute fatal canine distemper, the viral antigen was detected in a wide variety of tissues, including the cells of the lymphoid system, epithelial cells of skin, mucous membranes, lung, kidney, and cells of the CNS. The diagnostic importance of CDV antigen detection is discussed on the basis of these findings.

    Although it is well documented that the gut microbiota plays an important role in health and disease in mammalian species, this area has been poorly studied among carnivorous animals, especially within the mustelidae family. The gastrointestinal tract of carnivores is characterized by its short...... length and fast transit time, as compared to omnivores and herbivores, which is due to the low level of inherent fermentation. Mink represents an example of this, which have a GI tract only four times the length of the body and a transit time of approximately 4–5 hr. In this study, we used high...... interindividual differences in bacterial composition between individual animals being dominated generally by the phylum Firmicutes, but in some cases also Proteobacteria or Fusobacteria. The bacterial load and community structure within the mucus was not severely impacted by 3 days of fasting, which implies...

    The purpose of this article is to update general dentists and maxillofacial surgeons in the perioperative management of the pregnant patient. Pregnancy results in physiologic changes in almost all organ systems in the body mediated mainly by hormones; which influences the treatment schedule. Understanding these normal changes is essential for providing quality care for pregnant women. The general principles that apply in this situation are discussed, followed by the relevant physiologic changes and their treatment implications, the risks of various medications to the mother and fetus, the management of concomitant medical problems in the pregnant patient, appropriate timing of oral and maxillofacial surgery during pregnancy, and management of emergencies during pregnancy. Information about the compatibility, complications, and excretion of the common drugs during pregnancy is provided. Guidelines for the management of a pregnant patient in the dental office are summarized.

    Canine distemper virus (CDV) infects a variety of carnivores, including wild and domestic Canidae. Genetic/antigenic heterogeneity has been observed among the various CDV strains, notably in the haemagglutinin (H) gene, that appears as a good target to gather epidemiological information. Based on sequence analysis of the H gene, wild-type CDV strains cluster into distinct geographic lineages (genotypes), irrespective of the species of isolation. The sequence of the H gene of 28 CDV strains detected from both vaccinated and non-vaccinated breeding foxes, raccoon dogs and minks from different geographical areas of China during the years 2004-2008 was determined. All the CDV strains but two (strains HL and HLJ2) were characterized as Asia-1 genotype and were highly similar to each other (96.2-99.7% at the amino acid [aa] level) and to other Asia-1 strains (96.1-99.5% aa) previously detected in China. The CDV strains HL and HLJ2 were both collected from foxes in Heilongjiang province in 2005. Strain HL resembled CDVs of the Arctic genotype (GR88-like) and displayed high aa identity (98.0%) to the Chinese canine strain Liu. By converse, strain HLJ2 was barely related to CDVs of the Asia-2 genotype (88.7-90.3% aa identity), and could represent a novel CDV genotype, tentatively proposed as Asia-3. These results suggest that at least three different CDV genotypes, distantly related (81.8-91.6% aa identity) to the vaccine strains, Onderstepoort-like (America-1 genotype), are currently circulating in breeding foxes, raccoon dogs and minks in China, and that the genotype Asia-1 is predominant. Whether the diversity between wild-type CDVs and the vaccine strains may affect, to some extent, the efficacy of the vaccines deserves further investigations.

    The growth characteristics were studied in the attenuated strains of canine parvovirus CPVA-BN 80/82, mink enteritis virus MEVA-BN 63/82 and feline panleucopenia virus FPVA-BN 110/83 on the stable feline kidney cell line FE, and in the attenuated canine distemper virus CDV-F-BN 10/83 on chicken embryo cell cultures (KEB) and cultures of the stable cell line VERO. When the FE cultures were infected with different parvoviruses in cell suspension at MOI 2-4 TKID50 per cell, the first multiplication of the intracellular virus was recorded 20 hours p. i. In the canine parvovirus, the content of intracellular and extracellular virus continued increasing parallelly until the fourth day; then, from the fourth to the sixth day, the content of extracellular virus still increased whereas that of intracellular virus fell rapidly. In the case of the mink enteritis virus the release of the virus into the culture medium continued parallelly with the production of the cellular virus until the sixth day. In the case of the feline panleucopenia virus the values concerning free virus and virus bound to cells were lower, starting from the second day p. i. When KEB or VERO cultures were infected in cell suspension with the canine distemper virus at MOI about 0.004 per 1 cell, the replicated intracellular virus was first recorded in the KEB cultures five hours after infection but in the VERO cultures only 20 hours after infection, with a timely release of the virus into the culture medium in both kinds of tissue. In the KEB and VERO cultures the highest values of infection titres were recorded on the fourth day p. i., the course of virus multiplication on the cells being parallel with its release into the culture medium.

    To explore patterns and levels of self-esteem of pregnant substance abusers. A descriptive prospective study to describe the self-esteem of pregnant substance abusers. Subjects (N = 31) were abusing and dependent on three or more legal and/or illegal substances. Subjects were asked one open-ended question regarding their self-esteem, then the Rosenberg Self-Esteem Inventory (RSI) was administered. Subjects gave 46 responses to the open-ended question. Overall, they used a single word to describe self-esteem. The most frequent response on the RSI was "low" for self-esteem, 23 subjects used positive terms, 20 used negative terms, and 3 reported a neutral term. The RSI confirmed the aspects of low self-esteem. Problems with low self-esteem were evident. Intervention strategies need to be developed to increase self-esteem in pregnant substance abusers.

  7. Iodine Status in Pregnant & Breastfeeding Women

    DEFF Research Database (Denmark)

    Andersen, Stine Linding

    Iodine is required for the synthesis of thyroid hormones, which are crucial regulator of early brain development. The source of iodine in the fetus and the breastfed infant is maternal iodine, and adequate iodine intake in pregnant and breastfeeding is of major concern. Severe iodine deficiency can...... cause irreversible brain damage, whereas the consequences of mild to moderate iodine deficiency are less clear.

    The aim of the paper was to determine the frequency and intensity of tobacco smoking by pregnant women as well as to find out the relationship between tobacco smoking during pregnancy and socioeconomic variables (education, marital status, professional career, smoking partner, number of children) as well as health variables (severe ailments during pregnancy period, taking medicines, using medical care). The research was carried out at the department of gynecology and obstetrics of the Specialist Hospital in Jasło as well as at the Women's Outpatient Clinic of the Public Independent Health Service Institution in Skołyszyn (Podkarpackie Voivodship). The research was conducted by means of the questionnaire distributed from July to September 2002 among 100 pregnant women. The results of the analysis indicate that 18% of the women under survey smoked cigarettes during pregnancy, including 6% daily smokers and 12% occasional smokers. 18% of women quitted smoking when they found out that they were pregnant, and 18% of them limited smoking. Exposure to passive smoking at their family home was declared by more than a half of the pregnant women, while 14% of the surveyed women mentioned passive exposure to smoke at their workplace. The socioeconomic variables that most clearly showed positive correlation with active smoking by pregnant women were: smoking tobacco by a husband or steady partner, smoking tobacco in the presence of a pregnant woman in her workplace and at home, as well as taking advantage of a family doctor's advice. Smoking tobacco during pregnancy was also enhanced by: the lower level of education, extramarital pregnancy, permanent residence in a town or a city, poor living conditions, not working professionally during pregnancy, having two or more children, abnormal course of pregnancy, suffering from such ailments as: weepiness, problems with relaxation, lack of appetite and taking no medicines during pregnancy.

    To compare the frequency of an ASCUS Pap Smear result in pregnant and non-pregnant women, stratified by age group. We analyzed the results of 1,336,180 cytopathologyc exams of Pap smears performed between 2000 and 2009 (ten years) with the purpose of screening for cervical carcinoma. Comparisons were made between pregnant and non-pregnant women, and the sample was stratified into three age groups (20-24, 25-29 and 30-34 years). The χ2 test was used and the magnitude of association was determined by the by Odds Ratio (OR) with the 95% confidence interval (95%CI). A Total of 447,489 samples were excluded on the basis of the criteria adopted, for a total final sample of 37,137 pregnant women and 851,554 non-pregnant women. An ASCUS result was detected in 1.2% of cases, with a significant difference between pregnant and non-pregnant women in the age groups of 20-24 years (OR=0.85; 95%CI 0.75-0.97) and 25-29 years (OR=0.78; 95%CI 0.63-0.96). There was no difference in the group between 30-34 years (OR=0.76; 95%CI 0.57-1.03). This study suggested that non-pregnant women have a higher frequency of ASCUS, most evident in the age group of 20 to 29 years. The collection of cervical cancer screening should not be a compulsory part of the prenatal routine.

    The aim of the study was to investigate oxidative stress during normal pregnancy in female dogs based on an evaluation of plasma markers for lipid and protein peroxidation. Twenty clinically healthy female dogs (10 non-pregnant and 10 pregnant) were used in the study. Blood samples from the pregnant animals were collected at 19-21, 38-40, and 56-58 days of pregnancy. Blood samples from non-pregnant female dogs were obtained between 20 and 35 days after ineffective breeding. As indicators of oxidative stress, we measured the following using spectrophotometric and spectrof- luorimetric methods: thiobarbituric acid reactive substances (TBARS), radical cations of N,N, diethylparaphenylene diamine (RC-DEPPD), sulfhydryl groups (SH groups), bityrosine and formylkynurenine. The mean plasma TBARS concentration in the pregnant dogs (0.486 ± 0.071-0.581 ± 0.191 μmol/g protein) was significantly higher (p pregnant animals (0.274 ± 0.111 μmol/g protein). A marked, although not significant, decrease in SH group content, as well as an increase in bityrosine and formylkynurenine concentration were concurrently observed in the pregnant dogs. No significant differences were found in terms of the studied markers in the pregnant animals when comparing the values obtained during the investigated periods of pregnancy, although there was a progressive decrease in TBARS concentration and a progressive increase in RC-DEPPD, bityrosine and formylkynurenine contents. Our findings suggest that normal pregnancy in female dogs is associated with oxidative stress. Further studies are necessary to establish the physiological ranges of antioxidative/oxidative profiles in pregnant dogs and to explain if and how the intensity of oxidative stress might contribute to the risk of the complications of pregnancy.

    H. Ben Nasr

    2007-01-01

    Full Text Available Scorpion envenomation is common in many countries; however, its effects on pregnancy are still unclear. In the present paper, we described the effects of scorpion envenomation on pregnant patients. A retrospective study was carried out considering the clinical and laboratory exams of patients admitted to the emergency room of Habib Bourguiba Hospital, Sfax, Tunisia, from 1990 to 2004. Variability of these clinical and laboratory profiles according to maternal age, gestational age and number of previous parities was also discussed. Among 167 scorpion-envenomed women, age ranged from 17 to 42 years, 7.18% were pregnant. These presented symptoms similar to those of non-pregnant women envenomed by scorpions. Two pregnant patients developed intense pelvic pain and one manifested vaginal bleeding. Although the studied parameters showed non-significant differences, we could conclude that scorpion envenomation may lead to abnormal uterine contraction probably causing preterm delivery. Maternal disturbances induced by scorpion envenomation may influence the fetus development. The effects were more severe in the second trimester of pregnancy.

    1992-09-01

    This report presents a pair of wildlife exposure models developed for use in investigating the risks to wildlife of releases of mercury and PCBS. The species modeled are the great blue heron and mink The models may be used to estimate the exposure experienced by mink and herons, to help establish remedial action goals and to identify research needs. Because mercury and PCBs bioaccumulate through dietary uptake, the models simulate the food webs supporting the two species. Sources of contaminants include surface water, sediment, sediment pore water, and soil. The model are stochastic equilibrium models. Two types of variance in the input parameters are distinguished: stochastic variance among individual mink and herons and ignorance concerning true parameter values. The variance in the output due to stochastic parameters indicates the expected variance among the receptors. The variance due to ignorance indicates the extent to which the model outputs could be unpaved by additional sampling and measurement. The results of the models were compared to concentrations measured in great blue heron eggs and nestlings from colonies on the Clinch and Tennessee Rivers. The predicted concentrations agreed well with the measured concentrations. In addition, the variances in measured values among individuals was approximately equal to the total stochastic variance predicted by the models

    Full Text Available Sleep problems are common complaints among pregnant women. This study was designed to compare subjective sleep problems in non-pregnancy condition, healthy and preeclamptic pregnancy as a major complication of pregnancy. We hypothesized that some sleep problems are more prevalent in females with preeclampsia.In this cross-sectional study, 102 women with preeclampsia, 106 healthy pregnant women in the third trimester and 103 healthy non-pregnant women were selected through random sampling. Age and parity were matched in the three groups. We used Global sleep assessment questionnaire (GSAQ to check the subjective sleep problems, and then we performed statistical analysis using Analysis of variance (ANOVA and Pearson Chi-square tests.Our findings revealed significant differences in initial insomnia (p = 0.034, fragmented sleep (p = 0.022, snoring (p<0.001, non-idiopathic insomnia (p = 0.045 and sadness and anxiety (p = 0.001 between the three groups. Some sleep problems were more common in preeclampctic compared to healthy pregnant women including initial insomnia, fragmented sleep, snoring, sleep apnea and non-idiopathic insomnia. Moreover, the subjects with preeclampsia revealed more fragmented sleep, snoring, sadness and anxiety and lack of getting enough sleep due to other activities compared to non-pregnant women.Different kinds of sleep problems can occur in subjects with preeclampsia in comparison with the non-pregnant and healthy pregnant subjects. Sleep problems should be evaluated during pregnancy, particularly in pregnant women with preeclampsia, and suitable treatment should be provided for any specific sleep problem.

    Full Text Available Background: Our understanding of pathogenesis of periodontal disease has changed remarkably over a few decades. Rather than being confined to periodontium, periodontal disease may have a wide ranging systemic effects. It is now recognized that it shares most of the common risk factors for diabetes, coronary heart disease preterm low birth weight, miscarriage or early pregnancy loss and preeclampsia. Materials and Methods: The study group comprised of 400 women (200 pregnant women and 200 non-pregnant with an age range of 18-40 years. Maternal demographic and medical data were collected. Periodontal examinations included: Oral hygiene index (OHI-S, gingival index (GI, pocket probing depth and clinical attachment loss (CAL. Results: The results were analyzed using test of proportion when OHI-S was compared in pregnant women with that of non-pregnant individuals, there was no significant difference in good oral hygiene group (P = 0.187, Z = 1.32. When the GI index was evaluated, a definite statistical difference was noted in mild, moderate and severe gingivitis (P - 0.000, Z = 0.365; P - 0.00, Z = 4.17; P - 0.000, Z = 0.75. CAL index revealed a statistical difference was observed healthy periodontium, mild, moderate and severe periodontitis in both pregnant and non-pregnant women (P = −0.000, Z = 3.65; P - 0.000, Z = 5.83; P - 0.001, Z - 3.24; P - 0.000, Z - 6.47. Conclusion: The present study conducted supports the hypothesis that there is a definite correlation between the pregnant women and poor oral hygiene (gingivitis and periodontitis as compared with the non-pregnant controls.

    Full Text Available ABSTRACT Several studies present different methodologies and results about intensity exercise, and many of them are performed in male rats. However, the impact of different type, intensity, frequency and duration of exercise on female rats needs more investigation. From the analysis of blood lactate concentration during lactate minimum test (LacMin in the swimming exercise, the anaerobic threshold (AT was identified, which parameter is defined as the transition point between aerobic and anaerobic metabolism. LacMin test is considered a good indicator of aerobic conditioning and has been used in prescription of training in different exercise modalities. However, there is no evidence of LacMin test in female rats. The objective was to determine AT in non-pregnant and pregnant Wistar rats. The LacMin test was performed and AT defined for mild exercise intensity was from a load equivalent to 1% of body weight (bw, moderate exercise as carrying 4% bw and severe intensity as carrying 7% bw. In pregnant rats, the AT was reached at a lower loading from 5.0% to 5.5% bw, while in non-pregnant the load was from 5.5% to 6.0% bw. Thus, this study was effective to identify exercise intensities in pregnant and non-pregnant rats using anaerobic threshold by LacMin test.

    In this study, we used a combined approach based on 2-dimensional electrophoresis (2-DE), difference in gel electrophoresis (DIGE), and mass spectrometry (MS) to identify the plasma protein composition in pregnant female dogs and compared it with non-pregnant female dogs. We used the plasma samples obtained from four female dogs during I, II, and III thirds of pregnancy, three days after parturition, as well as from four non-pregnant female dogs in diestrus phase. Analysis of 2-DE gel image exhibited of 249 protein spots. The intensity of staining of 35 spots differed significantly (P dogs. We used matrix-assisted laser desorption/ionization-time of flight-mass spectrometry (MALDI TOF MS) to identify 47 spots corresponding to 52 different proteins. Five identified protein spots, including zinc finger BED domain-containing protein 5, hemoglobin subunit beta-2, integrator complex subunit 7, apolipoprotein A-I, and glutamyl aminopeptidase were differentially presented in the plasma of pregnant and non-pregnant female dogs. To the best of our knowledge, this is the first report on the plasma protein profile of pregnant and non-pregnant female dogs. In this study, we identified proteins that have not been previously identified in dogs. Our findings showed that numerous protein spots were differentially presented in the plasma of female dogs during normal pregnancy. Although we identified only a limited number of differentially presented proteins, our study demonstrated that the plasma protein profile changed during pregnancy in female dogs, which suggests its importance in maintaining pregnancy. Further studies are necessary to define complete plasma protein profile of pregnant female dogs and to identify all proteins that are differentially presented in the pregnant animals compared with the non-pregnant ones. In addition, studies are warranted to explain the role of those proteins in maintaining the pregnancy and their usefulness in detection of early pregnancy

  6. Options Counseling for the Pregnant Adolescent Patient.

    Science.gov (United States)

    Hornberger, Laurie L

    2017-09-01

    Each year, more than 500 000 girls and young women younger than 20 years become pregnant. It is important for pediatricians to have the ability and the resources in their offices to make a timely pregnancy diagnosis in their adolescent patients and provide them with nonjudgmental pregnancy options counseling. Counseling includes an unbiased discussion of the adolescent's legal options to either continue or terminate her pregnancy, supporting the adolescent in the decision-making process, and referring the adolescent to appropriate resources and services. Pediatricians who choose not to provide such discussions should promptly refer pregnant adolescent patients to a health care professional who will offer developmentally appropriate pregnancy options counseling. This approach to pregnancy options counseling has not changed since the original 1989 American Academy of Pediatrics statement on this issue. Copyright © 2017 by the American Academy of Pediatrics.

    design was used and women were recruited during their first pregnancy-related visit to a general practitioner. The interviews were conducted using a semi-structured interview guide, and a thematic analysis of the data was carried out. RESULTS: Women made their hospital choice decision independently......OBJECTIVE: To investigate pregnant women's decision making in relation to their choice of birthing hospital and, in particular, their priorities regarding hospital characteristics. METHODS: The focus of this study was the choice of birthing hospital among pregnant women. A qualitative interview...... and they relied extensively on their own or peers' experiences. Travel distance played a role, but some women were willing to incur longer travel times to give birth at a specialized hospital in order to try to reduce the risks (in case of unexpected events). The women associated the presence of specialized...

    Objective validation of smoking status is necessary. Earlier studies have used saliva cotinine concentrations between 14.2 and 30 ng/ml as cut-off values to distinguish pregnant smokers from non-smokers. However, these cut-offs derive from studies including men and non-pregnant women....... This constitutes a problem, as recent studies have reported an accelerated metabolism in pregnant smokers. The aim of this study was to determine the optimum cut-off cotinine level distinguishing pregnant smokers from pregnant non-smokers....

    Pregnant prisoners have health-care needs that are minimally met by prison systems. Many of these mothers have high-risk pregnancies due to the economic and social problems that led them to be incarcerated: poverty, lack of education, inadequate health care, and substance abuse. Lamaze educators and doulas have the opportunity to replicate model programs that provide these women and their children with support, information, and empowering affirmation that improve parenting outcomes and decrease recidivism.

    Full Text Available Background: Women’s empowerment programs during pregnancy focus primarily on increasing women’s health goals and psychological empowerment has been considered important in most issues related to pregnant mothers’ mental health. Using path analysis, this study aims to examine the direct and indirect components of psychological empowerment of pregnant mothers. Methods: This model-testing study was conducted in Gorgan, northwest of Iran during three months in spring of 2015. Through random cluster sampling, a total number of 160 pregnant women were selected from 10 urban medical centers and clinics as primary centers. We used Spritzer’s Psychological empowerment scale. Suitable sampling based on Nunally and Bernstein was followed in the model. The relationships between the dependent variables were then examined by means of path analysis using Amos 18. Results: The psychological empowerment of pregnant mothers (PEPW model is impacted by individual factors, such as marriage age and employment, including some subjectively rated factors such as marital satisfaction and experience of violence. The PEPW model was deemed appropriate as optimum conditions indicators of goodness of fit; low index of χ2/df shows little difference between the conceptual model and observed data, while RMSEA value indicated the goodness of fit. Other indicators such as CMIN=0.957, CMIN/DF=0.957, P-CLOSE=0.418, χ2=0.957 and probability level=0.328 the fact that the model is ideal. The mothers’ employment had the highest coefficient in the PEPW path model .731 (0.443, 0.965 bootstrap confidence intervals by 95%, and with a p-value of less than 0.05. Conclusions: The mothers’ employment is the most important factor in psychological empowerment, but it cannot be addressed quickly. Programming to increase marital satisfaction followed by a decrease in family violence and prevention of early marriage are necessary for promotion of psychological empowerment during

    Information about asymptomatic plasmodial infection is scarce in the world, and the current antimalarial program goals (control, elimination, and eradication) demand this evidence to be well documented in different populations and malaria transmission settings. This study aimed to measure the prevalence of API in Colombian pregnant women at delivery. A retrospective prevalence survey was used. Women were recruited at hospital obstetric facility in each of the municipalities of Turbo, Necoclí in Antioquia department, and Puerto Libertador in Córdoba department. Malaria infection was tested by thick blood smear (TBS) and real-time quantitative PCR (qPCR). Ninety-six pregnant women at delivery were studied: 95% were asymptomatic (91/96), 45% had asymptomatic plasmodial infection (API) by qPCR (41/91), and only 8% (7/91) had API by microscopy. The prevalence of submicroscopic infections (TBS negative and qPCR positive) was very high, 37% (34/91) in asymptomatic women and 41% (39/96) in total women studied (91 asymptomatic and 5 symptomatic). The prevalence of API in Colombian pregnant women is much higher than which is expected for a country that does not have the level of malaria transmission as Sub-Saharan African countries.

    A female employee working in diagnostic radiology should take additional controls to protect the unborn child from ionizing radiations. The fetus is particularly sensitive to the effects of x-rays and, so, the determination of the equivalent dose to the unborn child is of interest for risk estimates from occupational exposures of the pregnant workers. The ian of this study is to develop a method for fetus dose estimate of a pregnant worker who participates in interventional radiology procedures. Factors for converting dosemeter readings to equivalent dose to the fetus have been measured using thermoluminescence dosimetry. Equivalent dose to the uterus is used to simulate the equivalent dose to the fetus during the first two months of pregnancy. Measurements at different depths are made to consider the variations in the position of the uterus between pregnant women. The normalized doses obtained are dependent on the beam quality. Accurate estimation of fetus doses due to occupational exposures can be made using the data provided in the current study. (Author)

    Domestic violence is accepted worldwide as an important health problem. Besides diagnosis and treatment process, there are difficulties when considering of medico-legal evaluation of pregnant women subjected to domestic violence. As a signatory of the ''Convention on the Elimination of All Forms of Discrimination Against Women (CEDAW)'' Turkey has certain commitments regarding domestic violence and made regulations on national law. The purpose of the present study is to demonstrate the prevalence of domestic violence during pregnancy among the women who applied to obstetrics clinics and evaluating of the participants' knowledge level about the legal legislation concerning domestic violence. Pregnant women attending for antenatal care to department of Gynecology and Obstetrics were interviewed using an anonymous and confidential questionnaire. The questionnaire used was a version of Abuse Assessment Screen with guidance of references. 28 (13.4%) women stated that they had been subjected to violence before pregnancy. Only 10 (4.67%) women had stated experience of violence during pregnancy. 148 (69.2%) of them had stated that they had no knowledge about any legislation concerning domestic violence in our country. We believe that society awareness should be increased and the health workers should be informed about their ethical and legal responsibilities concerning domestic violence during pregnancy. The knowledge and sensitivity of health care personnel in Prenatal Clinics and Family Planning Services should be increased and examination protocols should be provided about domestic violence against pregnant women.

    Data from two pregnant women contaminated with 137 Cs, body burdens of 0.2 and 300 MBq, respectively at the time of the Goiania accident, were compared. The first one, with lower body burden was exposed during the fourth month of pregnancy, while the second became pregnant three years and eight months after 137 Cs intake. For the first woman 137 Cs concentrations were equal for the mother, infant and placenta, indicating an easy and homogeneous transport of 137 Cs from mother to foetus. The whole body monitoring data from the second woman, who became pregnant four years after intake, did not show a reduction in biological half-life during the pregnancy. Cs concentration in the mother was found to be 13 times higher than in the infant. One possible reason for this result is that four years after intake, Cs is supposed to be concentrated mainly in skeletal muscle tissue. During the pregnancy the blood flux becomes higher in most of the organs and tissues except brain, liver and skeletal muscle tissue. (author)

    Protein turnover was studied in nine non-pregnant (NP) women, eight pregnant (P) and two gestational diabetic (GDM) women. Whole body protein turnover, synthesis and catabolism rates were measured using a single oral dose of 15 N-glycine followed by measurement of enrichment of urinary ammonia. Urinary 3-methylhistidine (3MH) excretion was measured for three consecutive days, including the day of the protein turnover study. Whole body protein turnover and synthesis rates did not differ between the P and NP women, although the synthesis rates tended to be higher in the P group. Gestational diabetic women appeared to have considerably higher rates of both turnover and synthesis. Pregnant women excreted significantly more urinary 3MH than did non-pregnant women. GDM women appeared to have lower 3MH excretion than the P women. Correlation between 3MH excretion and protein turnover rates was nearly significant (p = .06) in the NP women, but was poorly correlated (p = .43) in the P women, suggesting that muscles may be a less important site of whole body protein turnover in pregnancy than in the non-pregnant state

    Baleen is an incrementally-growing tissue of balaenopteran whales which preserves relatively well over time in museums and some archeological sites, and, therefore might be useful for studies examining long-term changes of metal levels in whales. This study examined Hg and stable C and N isotopic composition of baleen plates of the North Atlantic minke whale (Balaenoptera acutorostrata), which continues to be a food source for people in Greenland and elsewhere. We compared the Hg levels and stable isotopes of major tissues (kidney, liver and muscle) with those of baleen plates to see whether baleen could be used as a biomonitor of variations of Hg intake and diet both between individuals and within individuals over time. Mercury was significantly correlated with concentrations in all tissues (kidney, liver and muscle). Stable C and N isotopes in baleen were generally similar to those of muscle, which reflects the recent (approximately one month) feeding of the whale, but in some individuals there were significant differences between baleen and muscle. Sectioning of baleen into 1 cm longitudinal increments showed that these differences were due to marked dietary shifts by some individuals over time that had been recorded in the baleen but were lost from the muscle record. Whole baleen C and N isotopes were better correlated with tissue Hg levels, suggesting that baleen may provide a more reliable indicator of long-term average diet, which in turn may be better related to Hg accumulation in tissues than the shorter-term diet record contained in muscle.

    Meat samples of 84 minke whales (Balaenoptera acutorostrata) mainly from the Barents Sea, collected between 1 May and 16 August 2011, were analyzed for total mercury, methylmercury, cadmium, lead, total arsenic, inorganic arsenic and selenium. The average total mercury concentration found was 0.15 ± 0.09 mg/kg, with a range from 0.05 to 0.49 mg/kg. The molar ratio of selenium to mercury varied between 1.0 and 10.3. Cadmium content ranged from 0.002 to 0.036 mg/kg, while the content of lead in whale meat ranged from whale samples exceeded established EU maximum levels for metals in fish muscle, but 4.8% and 6.8% of the samples exceeded Japanese maximum levels for total mercury and methylmercury, respectively, in whale meat. There was only minor variations in element concentrations between whales from different geographical areas, and cadmium was the only element were the concentration increased with increasing length.

    Elevated plasma levels of an endogenous factor with digoxin-like immunoreactivity (DLIS) was recently found in pregnant women, and it has been postulated to play a role in the regulation of fluids and electrolytes, as well as in the pathogenesis of hypertensive disorders in pregnancy. The authors have studied the plasma levels of DLIS in normal women (before and after treatment with contraceptive pills) and in pregnant women (either normotensive or hypertensive), during the gestional and the post-partum period using a sensitive RIA method. In addition, the authors have measured the inhibition of binding activity of 3 H-ouabain to intact erythrocytes in 7 plasma samples collected from healthy adults and in 5 plasma samples of women in the second or third trimester of pregnancy. In 8 normal cycling women DLIS levels were similar during the follicular phase (24.9±6.2 pg/ml d.e.) and the luteal phase (22.6±4.7 pg/ml d.e.9. Six months treatment with different preparations of contraceptive pills did not affect the concentrations of DLIS. In a cross-sectional study performed on 171 healthy pregnant women a significant increase (p 3 Houbain extracts of pregnant women as compared to normal adults, with a significant correlation between the data obtained with RIA and RRA method. On the other hand, no significant differences in DLIS levels were found between singleton and 9 twin pregnancies, and also between non-hypertensive and 8 hypertensive pregnant women. This data confirm that the plasma concentration of an endogenous factor (or a group of substances) with cardiac glycoside-like activity is significantly increased in pregnant women. However, further studies are necessary to well charcterize the possible role of DLIS in the pathphysiology of hypertension in pregnancy

    The aim of this study is to determine the changes in serum protein and its fractions by using electrophoresis in Holstein cows during different months of pregnancy in comparison with non-pregnant cows and to determine hormonal levels including T4, T3 and progesterone hormones. The samples were taken from 40 pregnant cows during deferent months and 10 non-pregnant cows. Significant decrease in the levels of total protein, albumin and globulin were observed in the third and late month of pregnancy than in mid pregnancy where the values were 6.5, 3.1 and 3.4 g/dl for early months and 6.5, 3.2 and 3.3 g/dl for late month as compared to the non-pregnant cows. Significant increase in α-1globulin was observed during months of pregnancy by about 33.3%. The decrease in the levels of α-2, β and γ-globulins were recorded by about 10%, 45.3% and 21.6%, respectively. A marked decrease in T4 hormone (5.0 μg/dl) was observed in pregnant cows than in non-pregnant ones (7.1 μg/dl). Also, a decreasing T3 level (169 ng/dl) was recorded as compared to non-pregnant cows (221 ng/dl). High significant increase in progesterone level was recorded in the mid pregnancy until reached the maximum value (49.94 ng/ml) at the 7 th month of pregnancy then declined (2.42 ng/ml) at the late month of pregnancy. In conclusion, during pregnancy of Holstein dairy cows, a decline in protein fractions and thyroid hormonal levels were recorded during different months as compared to non- pregnant cows. The opposite trend was observed in progesterone levels. The increasing progesterone level at the mid pregnancy indicated its importance in the continuation of pregnancy and maintenance of fetus against maternal rejection.

    Full Text Available Abstract Background The World Health Organization endorses the use of artemisinin-based combination therapy for treatment of acute uncomplicated falciparum malaria in the second and third trimesters of pregnancy. However, the effects of pregnancy on the pharmacokinetics of artemisinin derivatives, such as artesunate (AS, are poorly understood. In this analysis, the population pharmacokinetics of oral AS, and its active metabolite dihydroartemisinin (DHA, were studied in pregnant and non-pregnant women at the Kingasani Maternity Clinic in the DRC. Methods Data were obtained from 26 pregnant women in the second (22 - 26 weeks or the third (32 - 36 weeks trimester of pregnancy and from 25 non-pregnant female controls. All subjects received 200 mg AS. Plasma AS and DHA were measured using a validated LC-MS method. Estimates for pharmacokinetic and variability parameters were obtained through nonlinear mixed effects modelling. Results A simultaneous parent-metabolite model was developed consisting of mixed zero-order, lagged first-order absorption of AS, a one-compartment model for AS, and a one-compartment model for DHA. Complete conversion of AS to DHA was assumed. The model displayed satisfactory goodness-of-fit, stability, and predictive ability. Apparent clearance (CL/F and volume of distribution (V/F estimates, with 95% bootstrap confidence intervals, were as follows: 195 L (139-285 L for AS V/F, 895 L/h (788-1045 L/h for AS CL/F, 91.4 L (78.5-109 L for DHA V/F, and 64.0 L/h (55.1-75.2 L/h for DHA CL/F. The effect of pregnancy on DHA CL/F was determined to be significant, with a pregnancy-associated increase in DHA CL/F of 42.3% (19.7 - 72.3%. Conclusions In this analysis, pharmacokinetic modelling suggests that pregnant women have accelerated DHA clearance compared to non-pregnant women receiving orally administered AS. These findings, in conjunction with a previous non-compartmental analysis of the modelled data, provide further evidence that

    Full Text Available The objective of this study was to determine the degree of mitochondrial DNA (mtDNA divergence between two subspecies of Mustela sibirica from Korea (M. s. coreanus on the Korean Peninsula and M. s. quelpartis on Jeju Island and to examine the taxonomic status of M. s. quelpartis. Thus, we obtained complete sequences of mtDNA cytochrome b gene (1,140 bp from the two subspecies, and these sequences were compared to a corresponding haplotype of M. s. coreanus, downloaded from GenBank. From this analysis, it was observed that the sequences from monogenic M. s. quelpartis on Jeju Island were identical to the sequences of four M. s. coreanus from four locations across the Korean Peninsula, and that the two subspecies formed a single clade; the average nucleotide distance between the two subspecies was 0.26% (range, 0.00 to 0.53%. We found that the subspecies quelpartis is not genetically distinct from the subspecies coreanus, and that this cytochrome b sequencing result does not support the current classification, distinguishing these two subspecies by pelage color. Further systematic analyses using morphometric characters and other DNA markers are necessary to confirm the taxonomic status of M. s. quelpartis.

    Full Text Available Background: Sexuality is an important part of women’s health, quality of life, and general well-being. There are many factors influencing the female sexual function, including psychological, physiological, couple relationship, and socio-cultural factors. Pregnancy plays an important role in the sexual function and behavior of women. Objective: This study aims to evaluate the sexual function and determine the prevalence of sexual dysfunction among women during pregnancy. Materials and Methods: The present cross-sectional study was conducted on 257 healthy pregnant women aging between18-40 years who had attended the antenatal clinic, Paymaneh Hospital, Jahrom, Iran between April and October 2011 Female Sexual Function Index (FSFI questionnaire was used for assessing the sexual function Results: The mean age of the participants was reported as 26.45±4.49 years. In addition, 143, 69, and 45 subjects were in their 1st, 2nd, and 3rd trimesters, respectively. Comparison of the second and the third trimesters revealed a significant difference in the scores of all FSFI domains and the mean total FSFI score was reported as 19.9±22.45. Among the study subjects, 197 ones (79.1% had sexual dysfunction (FSFI score <26.5, while only 52 (20.9% had normal sexual function (FSFI score ≥26.5. The sexual dysfunction among pregnant women was rated as 23.4%, 30.5%, and 46.2% in the 1st, 2nd, and 3rd trimesters, respectively. Conclusion: The prevalence of sexual dysfunction is high during pregnancy and reaches higher levels in the third trimester. Therefore, pregnant women and their partners need counseling about physical and psychological changes in pregnancy

    2015-01-01

    Objective: To characterize demographic and clinical features in pregnant women presenting with acute headache, and to identify clinical features associated with secondary headache. Methods: We conducted a 5-year, single-center, retrospective study of consecutive pregnant women presenting to acute care with headache receiving neurologic consultation. Results: The 140 women had a mean age of 29 ± 6.4 years and often presented in the third trimester (56.4%). Diagnoses were divided into primary (65.0%) and secondary (35.0%) disorders. The most common primary headache disorder was migraine (91.2%) and secondary headache disorders were hypertensive disorders (51.0%). The groups were similar in demographics, gestational ages, and most headache features. In univariate analysis, secondary headaches were associated with a lack of headache history (36.7% vs 13.2%, p = 0.0012), seizures (12.2% vs 0.0%, p = 0.0015), elevated blood pressure (55.1% vs 8.8%, p headache history (OR 4.9, 95% CI 1.7–14.5) had an increased association with secondary headache, while psychiatric comorbidity (OR 0.13, 95% CI 0.021–0.78) and phonophobia (OR 0.29, 95% CI 0.09–0.91) had a reduced association with secondary headache. Conclusions: Among pregnant women receiving inpatient neurologic consultation, more than one-third have secondary headache. Diagnostic vigilance should be heightened in the absence of a headache history and if seizures, hypertension, or fever are present. Attack features may not adequately distinguish primary vs secondary disorders, and low thresholds for neuroimaging and monitoring for preeclampsia are justified. PMID:26291282

    Pregnant and non-pregnant rats were continuously exposed for 21 days to an aerosol containing 0.2, 0.4, and 0.6 mg cadmium/m/sup 3/ air. Pregnant and non-pregnant rats exposed to clean air served as controls. The aerosol was generated by an ultrasonic nebulizer and was carried into inhalation chambers. The median aerodynamic diameters were on the order of 0.6 ..mu..m. After inhalation of cadmium aerosols, serum iron levels were not lowered significantly in adult rats. A polycythaemic response of non-pregnant rats was observed due to a direct stimulatory effect of cadmium on erythropoiesis. Polycythaemia was less marked in pregnancy, presumably due to iron loss to placenta and fetus. Disturbances of pulmonary gas exchange or decreased plasma volumes were excluded as causative mechanisms of polycythaemia. In pregnant rats there was a marked dose dependent decrease of the activity of the alkaline phosphatase after cadmium inhalation, while there was no effect in exposed non-pregnant rats. This decreased enzyme activity, together with slowed growth rates and hemolytic effect indicate a higher sensitivity to cadmium in pregnancy. Proteinuria was not found in neither pregnant nor non-pregnant rats. Therefore, it is concluded that in this respect cadmium intoxication by inhalation does not resemble human toxemia of pregnancy, as discussed in the literature.

    Results of own investigations of the authors as to the thymogene influence on correction of the repair system under the effect of chronic irradiation are discussed in the article. The influence of thymogene on the repair of DNA in lymphocytes of the spleen of minks has been investigated. Changes in the correlation between single- and double stranded DNA forms in a cell were determinated. It has been found that the quantity of DNA with single stranded breaks has considerably increased in animals under conditions of chronic irradiation. The use of thymogene promotes activation of repair processes in a cell.

  12. Standing working posture compared in pregnant and non-pregnant conditions.

    During pregnancy, an increase in body weight occurs together with changes in body weight distribution and in fit between body dimensions and workplace layout. These changes may cause alterations in working posture which may, in turn, have adverse consequences for the biomechanical load on the musculoskeletal system and so increase the risk of musculoskeletal disorders. Using photographic posture registration, the standing working posture was studied in 27 women during the last stage of pregnancy and after delivery (the experimental group). The women performed an assembly task while standing at various workplace layouts. The postural differences between the pregnant condition and the non-pregnant condition were studied and the effect of the various workplace layouts assessed. Ten non-pregnant controls were also studied twice to establish the effect of the time interval between the measuring occasions. We found that the women of the experimental group stood further from the work surface in the pregnant condition compared to the non-pregnant condition, the hips were positioned more backwards, and, in order to reach the tesk, they increased the flexion of the trunk, increased the anteflexion of the upper arms, and extended the arms more. At the workplace layout in which the work surface height was self-selected, the postural differences due to pregnancy were smallest or even absent, compared to the postural differences in the other workplace layouts studied. Ergonomists and workers in occupational health services should be alert to the consequences for the biomechanical load on the musculoskeletal system and the risk of development of health complaints caused by postural changes due to pregnancy. An adjustable workplace layout may prevent some problems.

  13. Achieving Body Weight Adjustments for Feeding Status and Pregnant or Non-Pregnant Condition in Beef Cows

    Background Beef cows herd accounts for 70% of the total energy used in the beef production system. However, there are still limited studies regarding improvement of production efficiency in this category, mainly in developing countries and in tropical areas. One of the limiting factors is the difficulty to obtain reliable estimates of weight variation in mature cows. This occurs due to the interaction of weight of maternal tissues with specific physiological stages such as pregnancy. Moreover, variation in gastrointestinal contents due to feeding status in ruminant animals is a major source of error in body weight measurements. Objectives Develop approaches to estimate the individual proportion of weight from maternal tissues and from gestation in pregnant cows, adjusting for feeding status and stage of gestation. Methods and Findings Dataset of 49 multiparous non-lactating Nellore cows (32 pregnant and 17 non-pregnant) were used. To establish the relationships between the body weight, depending on the feeding status of pregnant and non-pregnant cows as a function of days of pregnancy, a set of general equations was tested, based on theoretical suppositions. We proposed the concept of pregnant compound (PREG), which represents the weight that is genuinely related to pregnancy. The PREG includes the gravid uterus minus the non-pregnant uterus plus the accretion in udder related to pregnancy. There was no accretion in udder weight up to 238 days of pregnancy. By subtracting the PREG from live weight of a pregnant cow, we obtained estimates of the weight of only maternal tissues in pregnant cows. Non-linear functions were adjusted to estimate the relationship between fasted, non-fasted and empty body weight, for pregnant and non-pregnant cows. Conclusions Our results allow for estimating the actual live weight of pregnant cows and their body constituents, and subsequent comparison as a function of days of gestation and feeding status.

    Determining the subjective construction of psychosocial factors affecting pregnancy in adolescents in a sample of students. 68 students who had become pregnant during their adolescence were selected after reviewing their files and sampling by logical criteria. The implications of pregnancy on personal, family and academic conditions were analysed by means of life stories and in-depth interviews. Crises and adjustments appeared in family and affective structure during the first trimester of pregnancy which culminated in them accepting motherhood as part of their life project, thereby reproducing the single-mother stereotype. Accompaniment of the pair occurred mainly during the first months, followed by abandonment. Although prejudiced, the university community's support had a bearing on interest in personal and academic development and in the baby. Specialised referents were consulted which scared the girls due to their pathological emphasis, thereby leading to them consulting family sources. The pregnant girls' mothers provided ongoing support for their daughters; this was not true of the fathers with whom constant conflict was presented. The services offered by the university were little used even though their importance was recognised. Forming integral students require programmes preparing students to be responsible for motherhood and fatherhood. Prevention was conveyed as promoting healthy affective links and strengthening family and social communication.

    During pregnancy, physical and hormonal modifications occur. Morphologic alterations of the feet are found. These observations can induce alterations in plantar pressure. This study sought to investigate plantar pressures during gait in the last 4 months of pregnancy and in the postpartum period. A comparison with nulliparous women was conducted to investigate plantar pressure modifications during pregnancy. Fifty-eight women in the last 4 months of pregnancy, nine postpartum women, and 23 healthy nonpregnant women (control group) performed gait trials on an electronic walkway at preferred speeds. The results for the three groups were compared using analysis of variance. During pregnancy, peak pressure and contact area decreased for the forefoot and rearfoot. These parameters increased significantly for the midfoot. The gait strategy seemed to be lateralization of gait with an increased contact area of the lateral midfoot and both reduced pressure and a later peak time on the medial forefoot. In the postpartum group, footprint parameters were modified compared with the pregnant group, indicating a trend toward partial return to control values, although differences persisted between the postpartum and control groups. Pregnant women had altered plantar pressures during gait. These findings could define a specific pattern of gait footprints in late pregnancy because plantar pressures had characteristics that could maintain a stable and safe gait.

    To determine the eating behavior of pregnant women assisted by primary health care and to compare it with women at childbearing age in Brazilian capitals. A cross-sectional study conducted on 256 pregnant women in the second trimester of gestation, selected by drawing lots from those assisted by primary health care units of a municipality in the state of São Paulo in 2009/2010. Eating habits were investigated via a questionnaire adapted from the VIGITEL system, consisting of questions about eating habits in general and the frequency and consumption characteristics of food groups/specific foods. For tis comparison, we used the indicators reported by the VIGITEL system for women at childbearing age in Brazilian capitals in 2010. The analyses involved the presentation of frequency distribution and descriptive statistics with comparisons according to the age group. Most patients had breakfast every day (86.7%) and 45.7% habitually exchanged a main meal for a snack once or twice a week. A daily consumption of fruit, raw salad and vegetables was not reported by 48.8%, 41.8% and 55.1% of the women, respectively. Fish was reported to never or almost never be consumed by 64.4% of the pregnant women. At least once a week, 69.9% of them reported the consumption of soda, and 86.4% of wafers/cookies. The comparison between the pregnant women and women at childbearing age in capitals showed a close similar prevalence of overweight, and no difference in the regular consumption of fruit and vegetables. Meat containing excess of fat and whole milk were more consumed by pregnant women, with differences reported in all the age groups analyzed. On the other hand, the pregnant women reported a less regular intake of soft drinks. The actions that need to be performed in prenatal care are various and very important, promoting the consumption of specific foods and providing guidelines about eating behavior, while reinforcing healthy eating habits already present.

    The lack of human data available to inform evidence-based treatment for illness during pregnancy has led to calls for greater inclusion of pregnant women in research, but the extent of their current representation is poorly characterized. Our objective was to measure the current exclusion of pregnant women from industry-sponsored clinical trials as a baseline for future comparison. We compiled data from studies enrolling women of childbearing potential posted on www.ClinicalTrials.gov between 1 October 2011 and 31 January 2012. The review was limited to open United States-based phase IV interventional studies sponsored by the pharmaceutical industry evaluating treatment of conditions that may be experienced by but are not limited to pregnant women and did not involve a medication classified as potentially teratogenic. If there was no mention of pregnancy in the inclusion or exclusion criteria, we contacted a study representative to confirm that pregnant women could be enrolled. Of 558 qualifying industry-sponsored studies, five (1%) were designed specifically for pregnant women. Of 367 phase IV clinical trials with verified inclusion and exclusion criteria, 348 (95%) excluded pregnant women and 19 (5%) did not. We found the exclusion of pregnant women from industry-sponsored clinical trials to be common practice. Moving beyond reflexive exclusion and developing thoughtful criteria for inclusion of pregnant women in clinical research would likely advance the evidence base to inform treatment decisions during pregnancy and lead to better health outcomes for women and children.

    The purpose of this research is to analyze cessation text-messages written by pregnant smokers to elucidate the target population's preferred content and message attributes. To achieve this goal, the objectives of this study are three-fold; to qualitatively code messages written by pregnant smokers for frame, type of appeal, and intended target. Study participants were recruited as part of a larger trial of pregnant smokers who were enrolled in a text-messaging program or control group and surveyed 1 month post-enrollment. Each participant was asked to write a brief message to another pregnant smoker and two independent coders qualitatively analyzed responses. User generated messages (N = 51) were equally loss and gain framed, and the most common appeals were: fear, guilt, cognitive, hope and empathy, in order of most to least frequent. The target of the majority of the messages was the baby. Allowing pregnant smokers to write cessation text-messages for other pregnant women can provide relevant insight into intervention content. Specifically, pregnant smokers appear to equally promote gain and loss frames, but may prefer messages that include components of fear and guilt related to the impact of smoking on their baby. Additional research is needed to systematically uncover perspectives of pregnant smokers to ensure interventions are optimally effective.

The increased usage of AgNPs leads to a potential hazard to human health. However, the potential effects of AgNPs on animal models are not clear. This study was designed to investigate the potential impact of AgNPs on pregnant mice.Methods: The synthesis of AgNPs was performed using culture extracts of Bacillus cereus. The synthesized AgNPs were characterized by X-ray diffraction, Fourier transform infrared spectroscopy, and transmission electron microscopy. AgNPs were administrated into pregnant mice via intravenous infusion at 1.0 mg/kg doses at 6.5 days postcoitum (dpc. At 13.5, 15.5, and 17.5 dpc, the pregnant mice were euthanized, and the embryo and placenta were isolated. The meiotic status of oocytes was evaluated. DNA methylation studies were performed, and aberrant imprinting disrupted fetal, placental, and postnatal development. Quantitative real-time polymerase chain reaction analysis and Western blot were used to analyze various gene expressions.Results: The synthesized AgNPs were uniformly distributed and were spherical in shape with an average size of 8 nm. AgNPs exposure increased the meiotic progression of female germ cells in the fetal mouse ovaries, and maternal AgNP exposure significantly disrupted imprinted gene expression in 15.5 dpc embryos and placentas, such as Ascl2, Snrpn, Kcnq1ot1, Peg3, Zac1, H19, Igf2r, and Igf2; DNA methylation studies revealed that AgNPs exposure significantly altered the methylation levels of

    Full Text Available Background: Trichomonas vaginalis has been recognized as a cosmopolitan parasite of male and female genital tract. This study was conducted to determine the prevalence of asymptomatic trichomoniasis among pregnant women in Benin City, Edo State. Materials and Methods: A total of 300 patients and subjects consisting of 250 pregnant women attending antenatal clinics and 50 non-pregnant apparently healthy subjects who served as controls were recruited in this study. The age ranged from 20 to 40 years. High vaginal swab was collected from each participant and T. vaginalis was diagnosed by microscopy. Results: An overall prevalence of 2.8% of trichomoniasis was observed among pregnant women. Gestational age and educational status of pregnant women were significantly associated with the prevalence of trichomoniasis. Conclusion: Asymptomatic T. vaginalis infection is common in pregnancy. We recommend routine screening for this infection in order to reduce the potential adverse pregnancy outcomes.

    The purpose of this study was to examine the breastfeeding knowledge of pregnant working women and explore factors that affected their knowledge. This Turkish study included 260 healthy, working women in the last trimester of pregnancy. Two separate questionnaires developed by the researcher were used to collect data. The average knowledge score of pregnant women respondents for all questions were 6.03 ± 2.99 (range: 0 to 14). Pregnant women had the least knowledge about duration of expressing breast milk (21.9%) and safe storage conditions for breast milk (27.2%). They knew the most about methods to express breast milk (87.3%) and features of containers used to store expressed milk (80%). Study results indicated that working pregnant women need better prenatal education to continue safe breastfeeding after returning to work. Occupational health nurses should inform working pregnant women about expression and storage of breast milk during prenatal education. Copyright 2014, SLACK Incorporated.

The study involved 28 pregnant women aged 18-36 (mean age: 24.7 with a normal course of pregnancy. The patients consulted a doctor in the spring, summer or fall complaining of focal skin hyperpigmentation on the face, chin and chest area. Ten patients (35.7% developed hyperpigmentation prior to their pregnancy and 18 women (64.3% - during the pregnancy. As of the consultation date, the pregnancy terms in all of the patients were 18-20 weeks. Chloasma was diagnosed by using dermatoscopy and skin examination with the Wood’s lamp. The patients were informed about the content and procedure of the study and gave their consent to take part in the study. Thin layers of Azelic (15% gel of azelaic acid for topical administration were applied to the hyperpigmented skin of the patients and gently rubbed twice a day (in the morning and evening as topical treatment for four months. The treatment results were assessed taking into consideration the patient’s subjective assessment, study group structure depending on the clinical efficacy, percentage of adverse events, and survey results based on the Dermatology Life Quality Index questionnaire. To reveal any potential general toxicological effects of the treatment, hepatic samples, total blood count and coagulogram results were analyzed as a part of obstetrical and gynecologic care for pregnant women. Key findings. Positive dynamics of the following characteristics was revealed: subjective assessment of treatment results by the patients, clinical efficacy of treatment and life quality index. Therapeutic results were observed as early as after one month but not later than three months after the treatment began. The therapeutic efficacy was recorded in 92.9-96.4% of all cases after four months of treatment: pigment spots disappeared or

    2007-05-01

    At times, obstetricians are called upon to assist pregnant women in making clinical choices between options that may selectively disadvantage either the mother or the fetus. If a mother chooses a therapeutic course that disadvantages the fetus the physician may feel distressed. In this paper we argue that the choices made by mothers are almost always in the interests of the fetus, and supported by physicians. When there is disagreement it is often due to poor communication. While acknowledging that the rare circumstances in which the physician and patient wish to pursue different clinical paths can be stressful for the provider, we explain why obstetricians should accept the judgment of their patient in all instances. Finally, we will maintain that positing a choice between maternal and fetal interests is, in fact, creating a false choice, in as much as options are presented as being exclusive, when in fact that is not the case.

    The purpose of this study was to evaluate the presence of HIV-1 in cervico-vaginal secretions of pregnant as compared to non-pregnant HIV-seropositive women. We compared 43 known HIV seropositive pregnant patients versus 241 age-matched (± 2 years) control non-pregnant HIV-seropositive subjects. In pregnant patients blood and cervico-vaginal samples were obtained during each trimester of pregnancy. In control subjects the same samples were obtained at enrolment. HIV-1 RNA was measured in plasma; proviral HIV-1 DNA, cell-associated and cell-free HIV-1 RNA in cervico-vaginal secretion by competitive polymerase chain reaction (cRT-PCR) and reverse transcriptase PCR. The genital shedding of HIV-DNA (22/43 as compared to 79/241, p = 0.02), and cell-free HIV-RNA detection (26/43 as compared to 72/241, p pregnant than in non pregnant women. Pregnancy correlated with a significant positive trend in the cervico-vaginal load of HIV-DNA (Spearman Rho= 0.149, p= 0.012), and cell-free HIV-RNA (Spearman Rho= 0.253, p HIV-RNA transcripts (Spearman Rho = 0.06, p= 0.31). After correction for potential confounders, first trimester pregnant women had increased rates of genital HIV- DNA (odds ratio = 1.94, 95% confidence interval = 1.01 3.78) and cell-free HIV-RNA (odds ratio = 4.07, 95% confidence interval = 1.97 8.41) detection compared to nonpregnant controls. The shedding of genital HIV was increased in pregnant compared to non pregnant subjects, even in patients with undetectable viremia. In this low-risk HIV-positive population the risks of vertical or horizontal transmissions should not be underestimated.

This is done on the basis of analysing the scientific literature on farmed mink and their possible need for swimming. In the wild, American mink (Mustela vison) are semi-aquatic predators...

    Full Text Available Objective: This study aimed to compare serum adiponectin, visfatin, and omentin between non-pregnant and pregnant women in overall, non-obese, and obese subjects. Methods: There were 40 pregnant and 33 non-pregnant women classified by body mass index (BMI into non-obese or obese subjects. Fasting blood samples were collected in the morning for the non-pregnant group and before delivery for the pregnant group. Results: Plasma glucose levels were significantly lower, but plasma insulin levels were significantly higher in pregnant when compared to non-pregnant women in overall, non-obese, and obese women (p<0.05 all. The homeostasis model assessment of insulin resistance (HOMA-IR was significantly higher, but the quantitative insulin sensitivity check index (QUICKI was significantly lower only in obese pregnant when compared to obese non-pregnant women (p<0.01 all. However, in non-obese women, HOMA-IR and QUICKI were comparable between pregnant and non-pregnant women. Serum adiponectin, visfatin, and omentin were significantly lower in pregnant compared to non-pregnant women in overall, non-obese, and obese groups (p<0.05 all. In pregnant women, serum adiponectin and omentin levels were significantly lower in obese compared to non-obese pregnant women while serum visfatin levels were comparable in both groups. Serum adiponectin levels were highest followed by omentin and visfatin, respectively in both non-obese and obese pregnant groups. These results indicated that lower serum adiponectin, visfatin, and omentin in pregnant women might contribute to higher insulin resistance in pregnancy. Furthermore, serum adiponectin and omentin were reduced in increasing adiposity similarly to non-pregnant women. Conclusion: Lower serum adiponectin, visfatin, and omentin in pregnant women might lead to decreased insulin sensitivity in these women.

  9. Collagen Fiber Orientation and Dispersion in the Upper Cervix of Non-Pregnant and Pregnant Women.

    Full Text Available The structural integrity of the cervix in pregnancy is necessary for carrying a pregnancy until term, and the organization of human cervical tissue collagen likely plays an important role in the tissue's structural function. Collagen fibers in the cervical extracellular matrix exhibit preferential directionality, and this collagen network ultrastructure is hypothesized to reorient and remodel during cervical softening and dilation at time of parturition. Within the cervix, the upper half is substantially loaded during pregnancy and is where the premature funneling starts to happen. To characterize the cervical collagen ultrastructure for the upper half of the human cervix, we imaged whole axial tissue slices from non-pregnant and pregnant women undergoing hysterectomy or cesarean hysterectomy respectively using optical coherence tomography (OCT and implemented a pixel-wise fiber orientation tracking method to measure the distribution of fiber orientation. The collagen fiber orientation maps show that there are two radial zones and the preferential fiber direction is circumferential in a dominant outer radial zone. The OCT data also reveal that there are two anatomic regions with distinct fiber orientation and dispersion properties. These regions are labeled: Region 1-the posterior and anterior quadrants in the outer radial zone and Region 2-the left and right quadrants in the outer radial zone and all quadrants in the inner radial zone. When comparing samples from nulliparous vs multiparous women, no differences in these fiber properties were noted. Pregnant tissue samples exhibit an overall higher fiber dispersion and more heterogeneous fiber properties within the sample than non-pregnant tissue. Collectively, these OCT data suggest that collagen fiber dispersion and directionality may play a role in cervical remodeling during pregnancy, where distinct remodeling properties exist according to anatomical quadrant.

    Understanding the relationship between health insurance coverage and tobacco and alcohol use among reproductive age women can provide important insight into the role of access to care in preventing tobacco and alcohol use among pregnant women and women planning to become pregnant. We examined the association between health insurance coverage and both past month alcohol use and past month tobacco use in a nationally representative sample of women age 12-44 years old, by pregnancy status. The women (n=97,788) were participants in the National Survey of Drug Use and Health (NSDUH) in 2010-2013. Logistic regression models assessed the association between health insurance (insured versus uninsured), past month tobacco and alcohol use, and whether this was modified by pregnancy status. Pregnancy status significantly moderated the relationship between health insurance and tobacco use (p-value≤0.01) and alcohol use (p-value≤0.01). Among pregnant women, being insured was associated with lower odds of alcohol use (adjusted odds ratio [AOR]=0.47; 95% confidence interval [CI]=0.27-0.82), but not associated with tobacco use (AOR=1.14; 95% CI=0.73-1.76). Among non-pregnant women, being insured was associated with lower odds of tobacco use (AOR=0.67; 95% CI=0.63-0.72), but higher odds of alcohol use (AOR=1.23; 95% CI=1.15-1.32). Access to health care, via health insurance coverage is a promising method to help reduce alcohol use during pregnancy. However, despite health insurance coverage, tobacco use persists during pregnancy, suggesting missed opportunities for prevention during prenatal visits. Copyright © 2016 Elsevier Ireland Ltd.

    This study report documents the development of a finite element (FE) model for analyzing trauma in pregnant women involved in road accidents and help the design of a specific safety device. The model is representative of a 50th percentile pregnant woman at 26 weeks of pregnancy in sitting position. To achieve this, the HUMOS 2 model, which has been validated in a wide range of dynamic tests, was scaled to the morphology of a woman in the 50th percentile and coupled with a model of gravid uterus. During scaling, special attention was paid to the pelvic region which is known to differ considerably in morphological terms between men and women. The gravid uterus model includes a placenta, a fetus, uterosacral ligaments and the amniotic fluid by means of fluid structure interaction formulation. The uterus and the female model were coupled using an original method whereby the growth of an uterus was simulated to compress the abdominal organs in a realistic manner. The model was validated based on experimental tests described in the literature. Additional tests based on abdominal loadings with a seatbelt on Post Mortem Human Surrogates (PMHS) coupled to silicone uterus were also performed. Results highlighted the role of the possible interaction of the fetus in the pregnant woman abdominal response. Experimental corridors taking into account the presence of this fetus could therefore be proposed. © 2013 Elsevier Ltd. All rights reserved.

    Preeclampsia is characterized by an increase in high blood pressure and decrease in GFR and proteinuria, however, the underlying mechanisms are still unclear. Renalase is a recently discovered protein implicated in regulation of blood pressure in humans. Plasma concentrations of serum renalase were measured in healthy controls, healthy pregnant and pregnant with preeclampsia matched for age, gestational age, in the third trimester of pregnancy. Serum renalase levels were compared in pregnant with and without preeclampsia and non-pregnant controls. Factors associated with serum renalase levels in pregnancies were also evaluated. In healthy pregnant serum renalase levels were significantly higher than in controls. However, pregnant with preeclampsia had lower renalase levels than healthy controls. Serum renalase levels were inversely associated with blood pressure levels and positively correlated with glomerular filtration rate. The results indicated that the development of preeclampsia in pregnant is accompanied by altered serum renalase levels. High blood pressure and kidney damage that characterize this disorder are mediated at least in part by low renalase levels.

  17. Oral health knowledge of pregnant women. Systematic review

    María José Aguilar-Cordero

    2018-03-01

    Full Text Available Introduction: The oral health of pregnant women depends on the knowledge, attitudes and behaviors learned prior to pregnancy. Research shows that the most frequent and specific problem encountered during this period, which continues during lactation, is gestational gingivitis, that is, inflammation of the gums. Therefore, the knowledge that the pregnant woman has about these alterations is essential, not only to prevent them, but for the consequences that can have during pregnancy, childbirth and postpartum. Aim: To analyze the main studies on the level of oral health knowledge of pregnant women. Method: The systematic review was performed according to the PRISMA guidelines. We have selected 18 studies that analyze the subject matter. Results: The studies reviewed did not present similar samples at the time of assessing the level of knowledge of the oral health of pregnant women. This can create problems comparing studies with each other. The issue addressed to measure the knowledge of pregnant women served to determine this discernment, and thus orient the research towards those aspects that presented difficulties. Conclusions: All of the studies reviewed show that the level of knowledge of pregnant women about their oral health is regular. This result that the surveys show, is not validated by a unified protocol, this means that there is no unanimity when verifying the knowledge of pregnant women, in relation to their oral health, as a health problem in general.

    Concerns about including pregnant women in research have led to a dearth of evidence to guide safe and effective treatment and prevention of HIV in pregnancy. To better understand why these evidence gaps persist and inform guidance for responsible inclusion of pregnant women in the HIV research agenda, we aimed to learn what HIV experts perceive as barriers and constraints to conducting this research. We conducted a series of group and one-on-one consultations with 62 HIV investigators and clinicians to elicit their views and experiences conducting HIV research involving pregnant women. Thematic analysis was used to identify priorities and perceived barriers to HIV research with pregnant women. Experts discussed a breadth of needed research, including safety, efficacy, and appropriate dosing of: newer antiretrovirals for pregnant women, emerging preventive strategies, and treatment for coinfections. Challenges to conducting research on pregnancy and HIV included ethical concerns, such as how to weigh risks and benefits in pregnancy; legal concerns, such as restrictive interpretations of current regulations and liability issues; financial and professional disincentives, including misaligned funder priorities and fear of reputational damage; and analytical and logistical complexities, such as challenges recruiting and retaining pregnant women to sufficiently power analyses. Investigators face numerous challenges to conducting needed HIV research with pregnant women. Advancing such research will require clearer guidance regarding ethical and legal uncertainties; incentives that encourage rather than discourage investigators to undertake such research; and a commitment to earlier development of safety and efficacy data through creative trial designs.

    Full Text Available Objectives: The level of dental awareness of a pregnant woman affects the sanitary condition of her own teeth and the health of the child to be born. Poor oral health is considered to be a probable risk factor for the pre-term birth or low birth weight. The aim of this work was to assess the level of oral health knowledge that determines oral health condition of pregnant women in Poland. Material and Methods: Empirical data were obtained from the National Monitoring of Oral Health and Its Determinants, financed by the Ministry of Health. This socio-epidemiological study assessed oral health status and dental health awareness, which affects that status. Study subjects included 1380 pregnant women at the age ranging from 15 to 44, randomly-selected from urban and rural environments. Dental health status was recorded in the clinical examination sheets supplied by the World Health Organization, and the socio-medical data were recorded in the questionnaire interview sheets. Results: Almost 3/4 of the pregnant women evaluated their dental health as unsatisfactory or poor. Over 60% of the pregnant women rated their knowledge and practical skills concerning care of their own teeth and of the child to be born as limited, inadequate or none. Only 40% of the pregnant women provided right answers to the questions about dental issues. Conclusions: Low oral health awareness results in poor oral health status of the study subjects. A statistical pregnant woman has a total of 13 teeth showing the symptoms of tooth decay or caries. Over 70% of the pregnant women developed gingivitis or periodontitis. There is an urgent need in Poland to make the European principle of treating pregnant women as a dentally vulnerable group obligatory.

    Full Text Available Urinary system stones can be classified according to size, location, X-ray characteristics, aetiology of formation, composition, and risk of recurrence. Especially urolithiasis during pregnancy is a diagnostic and therapeutic challenge. In most cases, it becomes symptomatic in the second or third trimester. Diagnostic options in pregnant women are limited due to the possible teratogenic, carcinogenic, and mutagenic risk of foetal radiation exposure. Clinical management of a pregnant urolithiasis patient is complex and demands close collaboration between patient, obstetrician and urologist. We would like to review current diagnosis and treatment modalities of stone disease of pregnant woman.

    To evaluate attitudes and policies toward pregnant radiology residents, a questionnaire was sent to the chiefs of radiology residency programs across the country. A return rate of 76.4% and a response rate of 75.4% were achieved. A large majority of the respondents indicated that schedule changes would be made to avoid excessive exposure of a pregnant resident to radiation. The accommodations they suggest are reviewed, and suggestions are made that would help alleviate some of the stress and conflicts that invariably arise when a resident becomes pregnant

    The World Health Organization recommends intermittent preventive treatment in pregnancy (IPTp) with sulfadoxine-pyrimethamine for malaria for all women who live in moderate to high malaria transmission areas in Africa. However, parasite resistance to sulfadoxine-pyrimethamine has been increasing steadily in some areas of the region. Moreover, HIV-infected women on cotrimoxazole prophylaxis cannot receive sulfadoxine-pyrimethamine because of potential drug interactions. Thus, there is an urgent need to identify alternative drugs for prevention of malaria in pregnancy. One such candidate is mefloquine. To assess the effects of mefloquine for preventing malaria in pregnant women, specifically, to evaluate:• the efficacy, safety, and tolerability of mefloquine for preventing malaria in pregnant women; and• the impact of HIV status, gravidity, and use of insecticide-treated nets on the effects of mefloquine. We searched the Cochrane Infectious Diseases Group Specialized Register, the Cochrane Central Register of Controlled Trials (CENTRAL) in the Cochrane Library, MEDLINE, Embase, Latin American Caribbean Health Sciences Literature (LILACS), the Malaria in Pregnancy Library, and two trial registers up to 31 January 2018. In addition, we checked references and contacted study authors to identify additional studies, unpublished data, confidential reports, and raw data from published trials. Randomized and quasi-randomized controlled trials comparing mefloquine IPT or mefloquine prophylaxis against placebo, no treatment, or an alternative drug regimen. Two review authors independently screened all records identified by the search strategy, applied inclusion criteria, assessed risk of bias, and extracted data. We contacted trial authors to ask for additional information when required. Dichotomous outcomes were compared using risk ratios (RRs), count outcomes as incidence rate ratios (IRRs), and continuous outcomes using mean differences (MDs). We have presented all

    Full Text Available The objective of the study was to determine the volume, weight, measures, ovarian location and shape of the corpus luteum of pregnant and non - pregnant cows from zebu cows of the Colombian tropics. 528 reproductive tracts were collected; 264 pregnant and 264 non-pregnant of cows benefited at the local slaughterhouse in Monteria, Córdoba, Colombia. The period of collection of the samples was extended for three months. After collection of each reproductive tract, the ovaries were separated, identified as right and left, weighed and measured. Then the drawing of the location of the corpus luteum was performed on the ovary according to the anatomical planes previously established in the corresponding form. Subsequently the corpus luteum was removed to perform their measurements, weighings and visualization of their shape. There were statistical differences between the locations of the corpus luteum in the ovary: Anterior pole, posterior pole, free edge, upper face and lower face (p≤0.05. The weight and volume of gestational corpus luteum was greater by 30 and 27.9% than the corpus luteum of non-pregnant cows. The predominant form por shape of the corpus luteum in both pregnant and non-pregnant cows was oval, then pyramidal and finally rounded. No gestation was observed contralateral to the location of the corpus luteum.

    Early pregnancy failure has a profound impact on both human reproductive health and animal production. 2/3 pregnancy failures occur during the peri-implantation period; however, the underlying mechanism(s) remains unclear. Well-organized modification of the endometrium to a receptive state is critical to establish pregnancy. Aberrant endometrial modification during implantation is thought to be largely responsible for early pregnancy loss. In this study, using well-managed recipient ewes that received embryo transfer as model, we compared the endometrial proteome between pregnant and non-pregnant ewes during implantation period. After embryo transfer, recipients were assigned as pregnant or non-pregnant ewes according to the presence or absence of an elongated conceptus at Day 17 of pregnancy. By comparing the endometrial proteomic profiles between pregnant and non-pregnant ewes, we identified 94 and 257 differentially expressed proteins (DEPs) in the endometrial caruncular and intercaruncular areas, respectively. Functional analysis showed that the DEPs were mainly associated with immune response, nutrient transport and utilization, as well as proteasome-mediated proteolysis. These analysis imply that dysfunction of these biological processes or pathways of DEP in the endometrium is highly associated with early pregnancy loss. In addition, many proteins that are essential for the establishment of pregnancy showed dysregulation in the endometrium of non-pregnant ewes. These proteins, as potential candidates, may contribute to early pregnancy loss.

    Full Text Available Abstract Background Pregnant women are at an increased risk for HIV infection due to unknown biological causes. Given the strong effect of sex-hormones on the expression of immunomuodulatory factors, the central role of mucosal immunity in HIV pathogenesis and the lack of previous studies, we here tested for differences in immunomuodulatory factors in cervico-vaginal secretions between pregnant and non-pregnant women. Methods We compared concentrations of 39 immunomodulatory factors in cervicovaginal lavages (CVL from 21 pregnant women to those of 24 non-pregnant healthy women from the US. We used Bonferroni correction to correct for multiple testing and linear regression modeling to adjust for possible confounding by plasma cytokine concentration, cervical ectopy, total protein concentration, and other possible confounders. Cervical ectopy was determined by planimetry. Concentration of immunomodulatory factors were measured by a multiplex assay, protein concentration by the Bradford Method. Results Twenty six (66% of the 39 measured immunomodulatory factors were detectable in at least half of the CVL samples included in the study. Pregnant women had threefold lower CVL concentration of CCL22 (geometric mean: 29.6 pg/ml versus 89.7 pg/ml, p = 0.0011 than non-pregnant women. CVL CCL22 concentration additionally correlated negatively with gestational age (Spearman correlation coefficient [RS]: -0.49, p = 0.0006. These associations remained significant when corrected for multiple testing. CCL22 concentration in CVL was positively correlated with age and negatively correlated with time since last coitus and the size of cervical ectopy. However, none of these associations could explain the difference of CCL22 concentration between pregnant and non-pregnant women in this study, which remained significant in adjusted analysis. Conclusions In this study population, pregnancy is associated with reduced concentrations of CCL22 in cervicovaginal secretions

    The exhibition to the ionizing radiations of women, during the gestational period constitutes, with some frequency, the reason for preoccupation for the future mother and the medical professionals in charge to take care of them. The protection of the embryo-fetus against the ionizing radiations is from singular importance, given its special vulnerability to this physical agent, whereas on the other hand the processing or diagnosis with ionizing radiations is beneficial for the mother, only is it indirectly for the embryo-fetus, that exposes itself to a risk in exchange for anything. This work gathers the experience obtained in the dosimetric clinical evaluation of twenty one pregnant patients submitted to diverse procedures of radiation diagnosis or nuclear medicine during years 1999-2000. The main results obtained demonstrate that 25% of the patients were put under nuclear medicine procedures with aims therapeutic or diagnoses. The gestational age of the patients oscillated between 4 and 12 weeks. It can be conclude that in all the case the dose receive by the patient in all the body not surpass the 2 mSv, reason why to, conjugated with the gestational age, not exist evidence of risk for the embryo-fetus paradoxically in all cases his doctors have indicated to the patients to make the interruption of his pregnancy, what demonstrate the ignorance of some of the professional of the health on the biological effect of the ionizing radiation during the prenatal exhibition

    Quartered placentae from 12- and 15-day pregnant hamsters were incubated with 14 C labelled pregnenolone and progesterone and the products of their conversion were identified by chromatographic and isotope dilution methods. Pregnenolone was converted to progesterone, 7α-hydroxypregnenolone, 7α-hydroxyprogesterone, 3α-hydroxy-5β-pregnan-20-one, 3β-hydroxy-5α-pregnan-20-one, 3α-hydroxy-5α-pregnan-20-one, 5β-pregnane-3,20-dione and 5α-pregnane-3,20-dione. Except for 7α-hydroxypregnenolone, the same metabolites were identified in the incubates of the placental tissue with progesterone. Thus, the activity of Δ 5 -3β-hydroxysteroid dehydrogenase and Δsup(5→4) isomerase, 7α-hydrΔ 4 -5β- and Δ 4 -5α-reductase enzyme systems was shown in the hamster placenta. The formation of androgens from pregnenolone, progesterone and their 17-hydroxy-derivatives was not observed. There was also no evidence of the formation of estrogens from the above C-21 steroid precursors. (author)

    The hemoglobin concentrations during pregnancy in Filipinos belonging to the upper income group, who were prescribed 105 mg elemental iron daily, and who had acceptable levels of transferrin saturation, were examined in an attempt to define normal levels. The hemoglobin concentrations for each trimester followed a Gaussian distribution. The hemoglobin values equal to the mean minus one standard deviation were 11.4 gm/dl for the first trimester and 10.4 gm/dl for the second and third trimesters. Using these values as the lower limits of normal, in one group of pregnant women the prevalence of anemia during the last two trimesters was found lower than that obtained when WHO levels for normal were used. Groups of women with hemoglobin of 10.4 to 10.9 gm/dl (classified anemic by WHO criteria but normal in the present study) and those with 11.0 gm/dl and above could not be distinguished on the basis of their serum ferritin levels nor on the degree of decrease in their hemoglobin concentration during pregnancy. Many subjects in both groups, however, had serum ferritin levels less than 12 ng/ml which indicate poor iron stores. It might be desirable in future studies to determine the hemoglobin cut-off point that will delineate subjects who are both non-anemic and adequate in iron stores using serum ferritin levels as criterion for the latter.

  13. 18FDG PET in a pregnant patient

    A 26-year-old pregnant female presented with cervical adenopathy which was shown on biopsy to be Hodgkin's disease. As she had some systemic symptoms, It was decided to further stage her disease, with the options being allowing the pregnancy to continue, or terminating the pregnancy and treating immediately. To keep the radiation dose as low as possible, the administered dose of l8 FDG was reduced giving a total estimated dose to the fetus as 3.2 mGy and l37 Cs used as the source for attenuation correction rather than CT (dose estimated as 0.15mGy instead of 1.5 mGy) Total dose to the fetus was estimated as 3.4mGy. ICRP indicates that termination of pregnancy is not justified for radiation doses less than 100mGy. The findings confirm that an indicated PET scan may be performed in pregnancy at acceptable radiation dose. Relatively straightforward modification of the standard scanning protocol will reduce the estimated fetal dose. Copyright (2006) The Australian and New Zealand Society of Nuclear Medicine

    Full Text Available Research Question: What is the coverage level of immunization and other maternal services by a modified technique developed by IRMS (ICMR Delhi in comparison to standard WHO technique. Objectives: To study the â€"Coverage level for immunization, antenatal care and IFA tablets â€"Relationship of caste and education with the coverage levels. â€"Place and persons conducting deliveries. Study design: Cross-sectional. Setting: Both in rural and urban areas of Bihar. Participants: 375 mothers having children up to one year of age selected by a stratified random sampling technique developed by IRMS Delhi. Study variables: Immunisation status, antenatal care, Use of IFA tabs, Education of the female, Education of husband, place and person conducting the delivery. Statistical analysis: Proportions. Results: Overall immunization coverage was 42% for pregnant females. Coverage was high (60% in urban areas compared to rural areas (40%. Coverage was low among females from SC/ST category, also when females and their husbands were illiterates. Similar trend was observed for antenatal care and IFA tabs. 90% deliveries took place at home and were mainly attended by village dais. Majority of mothers received immunization from some. Govt. agency lack of, awareness and lack of motivation were more commonly found as reasons for non-immunisation among SC/ST as compared to others. Lack of awareness was also found as a common reason for non-immunisation among illiterate females.

  15. Pregnant woman mode for absorbed fraction calculations

    The most radiation-sensitive segment of our population is the developing fetus. Until recently, methods available for calculating the dose to the fetus were inadequate because a model for the pregnant woman was not available. Instead, the Snyder and Fisher model of Reference Man, which includes a uterus, was frequently used to calculate absorbed fractions when the source was in various organs of the body and the nongravid uterus was the target. These values would be representative of the dose to the embryo during the early stages of pregnancy. Unfortunately, Reference Man is considerable larger than Reference Woman. The authors recently reported on the design of a Reference Woman phantom that has dimensions quite similar to the ICRP Reference Woman. This phantom was suitable for calculating the dose to the embryo during early stages of pregnancy (0 to 3 mo.), but was not suitable for the later stages of pregnancy because of the changing shape of the mother and the displacement of several abdominal organs brought about by the growth of the uterus and fetus. The models of Reference Woman that were subsequently developed for each month of pregnancy are described. The models take into account the growth of the uterus and fetus and the repositioning of the various abdominal organs. These models have been used to calculate absorbed fractions for the fetus as a target and the gastrointestinal tract as a source of radiation for twelve photon energies ranging from 10 keV to 4 MeV

    Iron-deficient and normal pregnant rats were assigned to groups that either received a dose of cadmium (0.025, 0.050, or 0.100 mmole) plus 8 μCi of /sup 115m/Cd on day 18 of gestation or served as a nondosed group. Animals were either sacrificed 3 days after the dosing or allowed to litter (nondosed and 0.100 mmole cadmium groups only); pups and dams were sacrificed at 14 days of age. Viability of iron-deficient dams and fetuses and pups from iron-deficient dams was affected by the 0.100 mmole cadmium dose to a greater degree than was that in comparable normal animals. Although calculated amounts of cadmium deposited in the dam's liver, kidney, blood, tibia, and fetuses were greater in iron-deficient than in normal animals at all doses, differences were not significant except in the amount of cadmium accumulated in the placenta at the highest cadmium doses. Total deposition in the placentas/litter was similar for normal and iron-deficient groups at each dose level. The decreased viability may have been due to the dam's decreased food intake; blockage of nutrients, especially minerals, by cadmium--protein complexes in the placenta; or hormonal interruptions of pregnancy by steroid--cadmium complexes
