TY - JOUR. T1 - Dietary D-allulose alters cholesterol metabolism in Golden Syrian hamsters partly by reducing serum PCSK9 levels. AU - Kanasaki, Akane. AU - Jiang, Zhe. AU - Mizokami, Takuya. AU - Shirouchi, Bungo. AU - Iida, Tetsuo. AU - Nagata, Yasuo. AU - Sato, Masao. PY - 2019/9/1. Y1 - 2019/9/1. N2 - D-Allulose, a C-3 epimer of D-fructose, is a rare sugar reported to be a non-caloric sweetener having several health beneficial effects including anti-hyperglycemia and anti-obesity. However, the impact of dietary D-allulose on cholesterol metabolism remains unclear. Therefore, we studied the effects of D-allulose on the cholesterol metabolism of Golden Syrian hamsters, an animal model with a lipid metabolism similar to that of humans. Hamsters received either normal diet (ND) or high-fat diet (HFD) with or without 3% D-allulose for 4 or 8 weeks. While there were no significant differences in total serum cholesterol levels between the groups, D-allulose significantly increased HDL-cholesterol ...

AU - Allen, J. AU - Strain, JJ. PY - 1999/1. Y1 - 1999/1. N2 - Cholesterol oxides are cytotoxic and have been implicated in many disease processes; however, it has been proposed that cholesterol oxides result from cholesterol acting as a sacrificial antioxidant. In this study, the effect of dietary cholesterol on DNA damage, assessed by the alkaline comet assay, was examined in male and female Syrian hamsters. Animals were fed ad libitum a modified AIN-76 diet (control) or a diet with 0.5% cholesterol for 10 weeks. Following the 10-week feeding period, there was no significant difference in body weight between cholesterol-fed and control animals. Cholesterol feeding resulted in significant liver hypertrophy, and increased plasma total and HDL cholesterol in both male and female animals compared with ...

We attempted to alter the inherited myocardial damage and loss of contractility of the cardiomyopathic Syrian hamster (strain U-MX7-1) by giving cardiac drugs that altered intracellular calcium and myocardial workload. Thirty-seven 21-day-old cardiomyopathic and thirty-seven 21-day-old normal hamsters were divided into five groups each: verapamil-, propranolol-, digoxin-, hydralazine-, and saline-injected. On their 90th day of life, the hamsters were killed. Of the five cardiomyopathic groups, only verapamil reduced myocardial damage. When both control and cardiomyopathic hamsters were treated with saline, digoxin, or propranolol, the cardiomyopathic hamsters had significantly less contractile force, maximal rate of force development, and maximum velocity of unloaded shortening. When both groups were treated with verapamil or hydralazine, there were no significant group differences in the indices of contractility. However, when saline-treated cardiomyopathic hamsters were compared with ...

It has been shown previously that normal Syrian hamster embryo cells are neoplastically transformed by transfection with two cooperating oncogenes, v-myc plus v-Ha-ras. Karyotypic analyses of the cells from the tumors revealed a nonrandom chromosome change, monosomy of chromosome 15. In order to clarify the role of chromosome loss in these tumor cells with defined oncogene alterations, molecular and cytogenetic studies were performed on hybrids between normal Syrian hamster embryo cells and ras/myc tumor cells. Following fusion of the tumor cells with the normal cells which are not immortal, the majority of the cell hybrids senesced after ≤20 population doublings indicating that immortality was recessive. Some of the hybrids escaped senescence and grew indefinitely. These immortal hybrid cells retained the expected numbers of chromosome 15 indicating that escape from senescence did not involve loss of this chromosome. The tumorigenicity and anchorage-independent growth of the nonsenescent ...

Nuclear hormone receptor. The steroid hormones and their receptors are involved in the regulation of eukaryotic gene expression and affect cellular proliferation and differentiation in target tissues. Ligand-dependent nuclear transactivation involves either direct homodimer binding to a palindromic estrogen response element (ERE) sequence or association with other DNA-binding transcription factors, such as AP-1/c-Jun, c-Fos, ATF-2, Sp1 and Sp3, to mediate ERE-independent signaling. Ligand binding induces a conformational change allowing subsequent or combinatorial association with multiprotein coactivator complexes through LXXLL motifs of their respective components. Mutual transrepression occurs between the estrogen receptor (ER) and NF-kappa-B in a cell-type specific manner. Decreases NF-kappa-B DNA-binding activity and inhibits NF-kappa-B-mediated transcription from the IL6 promoter and displace RELA/p65 and associated coregulators from the promoter. Recruited to the NF-kappa-B response element of

Acts as a transcriptional repressor. Binds to E-box sequences in the immunoglobulin heavy chain enhancer as well as in the regulatory regions of many other tissue-specific genes. Represses E-cadherin promoter and induces an epithelial-mesenchymal transition (EMT) by recruiting SMARCA4/BRG1. Represses BCL6 transcription in the presence of the corepressor CTBP1. Positively regulates neuronal differentiation. Represses RCOR1 transcription activation during neurogenesis. Represses transcription by binding to the E box (5-CANNTG-3). Promotes tumorigenicity by repressing stemness-inhibiting microRNAs (By similarity).

Following treatment of Syrian hamster embryo cells with benzo(a)pyrene, the time required for the expression of enhanced fibrinolytic activity was examined. For this study, the fibrin-agarose overlay method was developed to distinguish the activity of normal and transformed colonies of hamster cells. Colonies possessing enhanced fibrinolytic activity were not observed 8 days after treatment, but they were observed following one passage (2 weeks after treatment). Morphologically transformed colonies, which exhibited no enhanced fibrinolytic activity, were observed 8 days following treatment. In contrast to these two early changes, cells capable of growth in soft agar were observed much later (6 to 8 weeks after treatment). Untreated Syrian hamster embryo cells generally senesced and did not exhibit enhanced fibrinolytic activity. Approximately 1 of 10 untreated cultures escaped senescence and evolved as a continuous cell line; such cultures frequently exhibited enhanced fibrinolytic activity. ...

Previous work on the early development of the golden hamster includes the investigation of Ochs (1908), Graves (1945) and Ward (1948), all at the level of the light microscope. Austin (1963) has examined the ultrastructure of the oocytes of the golden hamster while Enders & Schlafke (1965) have observed the pre-implantation stages of pregnancy.. The ultrastructure of implantation has been studied in two other species of myomorph rodents: the mouse (Potts, 1966a; Reinius, 1967) and the rat (Enders & Schlafke, 1967).. Implantation is taken as beginning when the zona pellucida is lost and the trophoblast is in contact with the uterine epithelium throughout its circumference. This takes place at between 80-100 h post coitum. Previous studies have been made on specimens embedded in paraffin, and the shrinkage which occurs with this method of preservation has caused implantation to appear to begin considerably later than this:Graves (1945) gives it as beginning at 5 days, Ward(1948) as 4 days 8 ...

In order to determine the causal factors in the development of the cardiomyopathy of the Syrian hamster, observations were made of myocardial histology, oxidative phosphorylation, high energy phosphate content, metabolism and mechanical activity of five age groups, ranging from 5 weeks to 10 months. Histological changes as well as biochemical abnormalities were present in the hearts of hamsters 5 weeks of age. With exception of a prolonged t-PH (time to peak height of contraction) period of the myopathic hearts of group I, tension development and contractility were normal up to 3 months of age. However, there was other evidence of disturbed function at 5 weeks of age, as shown by the length-tension curves. The significance and interrelationship of these findings are discussed. © 1970.. ...

Practice good handling daily to get your hamster used to this and be extremely, super-gentle, they truly are delicate little critters. Pick them up with the upmost care with both your hands as a scoop, and only handle them over a flat, soft surface - never at height in case they fall or jump. Be aware if you wake them in the daytime, they may bite - because as far as their concerned, its the middle of the night and youre simply a weird and intrusive predatory giant hand-thing looming around them.

In Mesocricetus auratus, synaptonemal complexes can be observed from birth up to 7 days of life. In foetuses from Mus musculus, synaptonemal complexes can be observed from the 14th day of gestation up to the first day post-partum, when the cells enter the dictyotene stage. In both species, synaptonemal complexes show, in general, the same morphology described in male cells by light and electron microscopy, with the exception that the axes of the sex bivalent are not identifiable. The leptotene stage can be identified although it is probably of short duration. Only one type of zygotene (zygote ne II of Dietrich and ...

PURPOSE: To study the integration of keloid heterograft in hamster (Mesocricetus auratus) cheek pouch. METHODS: The sample is formed by 18 male hamsters, heterogenic ones, aged between 10 and 14 weeks. Keloid fragments were obtained from keloid scars of the breast region of adult female mulatto patient. Each hamster received keloid fragments into both of its pouches, in a total of 36 grafted fragments. Animals were distributed into 6 groups for having their grafts assessed in the days 5, 12, 21, 42, 84, and 168. A macroscopic assessment is performed by comparing the pouch containing the grafted fragment, at each time point, with the same pouch in the immediate post surgical moment through a comparison of standardized photographs. Under microscope, the presence of blood vases is considered within the conjunctive tissue of the grafted fragment, as a criterion of its integration. Other events, as keratin secretion, the presence of cellular infiltrated, epithelium and keloid collagen fibers aspects ...

Play media Syrian hamsters (Mesocricetus auratus) are one of several rodents used in animal testing. Syrian hamsters are used to model human medical conditions including various cancers, metabolic diseases, non-cancer respiratory diseases, cardiovascular diseases, infectious diseases, and general health concerns. In 2014, Syrian hamsters accounted for 14.6% of the total animal research participants in the United States covered by the Animal Welfare Act. Since 1972 the use of hamsters in animal testing research has declined. In 2014 in the United States, animal research used about 120,000 hamsters, which was 14.6% of the total research animal use (under the Animal Welfare Act which excludes mice, rats and fish) for that year in that country. According to the Canadian Council for Animal Care, a total of 1,931 hamsters were used for research in 2013 in Canada, making them the sixth-most popular rodent after mice (1,233,196), rats (228,143), guinea pigs (20,687), squirrels (4,446) and voles (2,457). ...

Phytoestrogens are diphenolic, non steroidal compounds which are present in plants and are consumed by both humans and animals. Previous investigations have demonstrated that dietary phytoestrogens appear to have neurobehavioral effects on intermale aggression in male Syrian hamsters and the neural mechanisms require further exploration. In this study experiments involving a phytoestrogen (PE) and a phytoestrogen free (PE Free) diet were performed to determine whether or not diet had an effect on the expression of a and p estrogen receptors in the brain of male Syrian hamsters (Mesocricetus auratus). Twenty male hamsters were used for experimentation and animals were divided into a PE (n = 10) and a PE Free group (n = 10) for a period of 3 weeks. Animals were sacrificed, perfused and brains removed for subsequent protein extraction and immunohistochemisty. Estrogen receptors were quantified using western blot utilizing brains from both the PE and the PE Free group. Results revealed a wide spread

Calcium uptake was measured in homogenates and microsomal preparations enriched in sarcoplasmic reticulum vesicles isolated from hearts of hypertrophic (BIO 14.6) and dilated (BIO 53.58) cardiomyopathic as well as control (F1B) Syrian hamsters at 3, 7, 9, and 11 months of age. Calcium uptake studies were done using the Millipore filtration technique under conditions known to restrict transport to the sarcoplasmic reticulum. Steady-state calcium uptake capacity was used as a measure of the relative amounts of sarcoplasmic reticulum in homogenates prepared from individual hearts. At 3 months of age, there were no differences in calcium uptake in homogenates from control or myopathic hearts. However, by 9 months, although calcium uptake of homogenates from control and hypertrophic hearts was the same, calcium uptake by homogenates from dilated hearts was significantly depressed both in initial rate and capacity. Similar trends were seen in the microsomal vesicle preparations, but the decrease in ...

Primary Syrian hamster embryo (SHE) cells might be used to assess morphological transformation following treatment with chemical carcinogens. We employed attenuated total reflection Fourier-transform infrared (ATR-FTIR) spectroscopy to interrogate SHE colonies, as complex biomolecules absorb in the mid-infrared (IR; λ = 2-20 μm) giving vibrational spectra associated with structure and function. Early-passage SHE cells were cultured (pH 6.7) in the presence or absence of benzo[a]pyrene (B[a]P; 5.0 μg/ml). Unstained colonies were applied to an ATR crystal, and vibrational spectra were obtained in the ATR mode using a Bruker Vector 22 FTIR spectrometer with Helios ATR attachment. These were individually baseline-corrected and normalised. Spectra were then analysed using principal component analysis (PCA) plus linear discriminant analysis (LDA). PCA was used to reduce the dataset dimensions before LDA was employed to reveal clustering. This determined whether wavenumber-absorbance relationships ...

N2 - Signal transmission over a hippocampal network of CA3 and CA1 neurons in Syrian hamsters (Mesocricetus auratus), facultative hibernators, has not been fully characterized in response to oxygen-glucose deprivation (OGD). We hypothesized that during OGD, hippocampal signal transmission fails first at the synapse between CA3 and CA1 pyramidal neurons and that recovery of signal processing following OGD is more robust in hippocampal slices at cold temperature, from hamsters vs. rats, and from hibernating vs. non-hibernating hamsters. To test these hypotheses, we recorded fEPSPs and population spikes of CA1 neurons at 25 °C, 30 °C, and 35 °C in ...

Cheek pouches are more pronounced in certain rodents, such as hamsters, yet this structure is also distinguishable on certain species of rat, like the Gambian pouched rat, of which extensive morphological investigations have been conducted.[24] Aspects including rat pouch musculature, vascularization, and innervation were all explored and compiled through this and other studies. The widely distributed Rattus rattus is an example of the rodent family Muridae that lacks a true cheek pouch, rather, they exhibit more elastic cheeks (not true pouches) due to the organization of their cheek musculature. Concerning the musculature, the cheek pouch is composed primarily of a developed masseter (cheek) muscle that exhibits a high tensile ability. The masseter muscle has been shown to insert into the pectoralis muscles, allowing for a higher degree of food retention. The pouch is clearly divided between a buccal (cheek) and sublingual (below the tongue) portion. Volumetric analyses within this study ...

TY - JOUR. T1 - Evidence for refractoriness of the pituitary‐gonadal axis to the pineal gland in golden hamsters and its possible implications in annual reproductive rhythms. AU - Reiter, Russel J.. PY - 1972/7. Y1 - 1972/7. N2 - The testes of adult hamsters maintained in short daily photo‐periods (light:dark LD cycles of 1:23, in hours) undergo regression within ten weeks and spontaneous regeneration within about 30 weeks. Thereafter (at least up to 80 weeks), as long as these animals are kept in short photoperiods the gonads do not experience a second atrophic response. After the 30 week period of dark exposure, if the hamsters are moved into a long photoperiodic environment (LD 14:10) for either one or ten weeks and are then returned to short photoperiods, the gonads do not involute a second time. However, if the duration of exposure to LD 14:10 is increased to 22 weeks, the return to LD 1:23 causes the gonads to degenerate. The regressive responses of the testes never occur in hamsters ...

The present study clearly demonstrated that the production of ET-1 is markedly increased in the LV of Bio 14.6 cardiomyopathic hamsters at a stage of CHF. The chronic administration of an ETA antagonist, TA-0201, markedly improved the survival rate of cardiomyopathic hamsters. In addition, after 6 weeks of treatment, TA-0201 effectively prevented (1) the increase in LVEDP, RVEDP, and CVP; (2) the decrease in LV +dP/dt/Pmax and RV +dP/dt/Pmax; and (3) RV hypertrophy. These results suggest that chronic ET blockade improves the survival rate and ameliorates both LV and RV dysfunction in cardiomyopathic hamsters. Therefore, it is strongly suggested that endogenous ET-1 plays an important role in the deterioration of CHF due to cardiomyopathy in hamsters.. Cardiomyopathy, as well as myocardial infarction, is one of the major causes of CHF.19 It has been reported that plasma ET-1 level is increased in patients with cardiomyopathy.2 To date, however, the contribution of ET-1 in CHF caused by ...

First described in plants more than 270 years ago, circadian rhythms have been found in the vast majority of eukaryotes examined and in many prokaryotes. The basic mechanisms that are responsible for circadian rhythms are being elucidated in several model species. At the core of a circadian system is a molecular oscillator that generates a period of rhythmicity of about 24 h. The oscillator is self-sustaining, but it is influenced by environmental cues such as changes in light and temperature conditions (Dunlap, 1999). The oscillator controls a plethora of biological processes including nitrogen fixation in cyanobacteria (Johnson et al., 1996), scent emission in plants (Kolosova et al., 2001), conidiation inNeurospora crassa. (Pittendrigh et al., 1959), olfactory responses of Drosophila melanogaster (Krishnan et al., 1999), luteinizing hormone levels in birds (Follett et al., 1974), and wheel running activity in hamsters (Mesocricetus auratus; Ralph and Menaker, 1988). The fact that circadian ...

In mathematics and the arts, two quantities are in the golden ratio if the ratio of the sum of the quantities to the larger quantity is equal to (=) the ratio of the larger quantity to the smaller one. The golden ratio is an irrational mathematical constant, approximately 1.6180339887. Other names frequently used for the golden ratio are the golden section (Latin: sectio aurea) and golden mean. Other terms encountered include extreme and mean ratio, medial section, divine proportion, divine section (Latin: sectio divina), golden proportion, golden cut, golden number, and mean of Phidias. The golden ratio is often denoted by the Greek letter Phi, usually lower case (φ). (Source: Wikipedias Golden Ratio) ...

The most effective method to Properly Clean Your Hamster and Hamster Cage While the facts confirm that hamsters make incredible first pets, these creatures despite everything require a ton of commitment and care to assist them with living their most joyful and most beneficial lives. One zone that new hamster guardians probably wont know a great deal about is hamster prepping and, all the more explicitly, hamster natural surroundings cleaning and care. This is what each hamster parent has to know to guarantee that their textured bundle of fluff has a spotless and safe living space in which to live. Would you be able to give a hamster a shower? Hamsters are particular custodians and work superbly keeping themselves clean, showers, as we will in general consider them, are a bit much. In any case, it is conceivable to spot-clean them, on the off chance that they really need it. It is particularly essential to check their base as some of the time bedding can adhere in th ...

A former employee with the US Federal Bureau of Investigation (FBI) has said that American and NATO forces are training Syrian rebels in southeastern Turkish city of Hakkari.. Sibel Edmonds also said that she had received information from Turkish and US sources indicating that training Syrian opposition forces, led by defected Syrian colonel Riad al-Assad, had started in May, the Turkish daily Milliyet reported.. Edmonds further added that the US is involved in smuggling arms into Syria from Incirlik military base in Turkey in addition to providing financial support for Syrian rebels.. Syria has been experiencing a deadly unrest ever since mid-March, with demonstrations being held both against and in support of President Bashar al-Assads government.. Confessions by a number of Syrian rebels about foreign-sponsored plans to carry out armed operations and killing ordinary people as well as security forces prove that recent developments in the country are part of an attempt to incite a revolt in ...

The head of the Syrian National Council, Bourhan Ghalioun, has said in an interview that the Syrian uprising is self-reliant and not dependent on foreign support.

Fierce fighting between Syrian government forces and armed opposition groups has continued in the Quneitra province of the countrys southwest as locals report a massive build-up of troops and pro-government militias in several towns. Opposition groups retook Quneitra after the Syrian army briefly controlled it on Saturday, according to the UK-based Syrian Observatory for Human Rights. The escalation of clashes comes just days after the Syrian government launched a major offensive in the Quneitra province, situated on the border of the roughly 70 percent of the Golan Heights under Israeli occupation since 1967. Modar Shanwan, a spokesman for the Revolutionary Command Council in Quneitra and the Golan, a coalition of armed opposition groups, said that government forces breached [the Quneitra province] down the middle and were supported by militias and artillery bombardments. But the revolutionaries recovered control of the Samdaniah village over the weekend, he told Al Jazeera, referring to ...

There are a variety of commercially available hammie foods that have been especially formulate to provide your pet with the correct amounts of macronutrients, vitamins, and minerals. These often come in two forms: seed mixes and pellets.. Pellets are exceptional as these are carefully formulated to contain at least 20 percent protein which is essential for building tissues and improve the overall functioning of the little fellows organs. This is also important as hamsters are known to be very active especially on the exercise wheel. Protein gives them the ability to develop stronger muscles. Additionally, pellets are packed with other nutrients that your hammie needs. Sadly, it is very rare to see a hamster eat pellets with gusto.. Seed mixes are hamsters absolute favorite because these resemble the food that they eat in the wild. Unfortunately, focusing only on a few types of seeds can adversely affect their nutrition as some nutrients or substances may not be present in these seeds. For ...

The importance of this model revolves around the benign nature of HFMD. HFMD doesnt cause severe complications unless the infection becomes persistent. Establishment of a consistent disease in a small animal model allows researchers to analyze viral pathogenesis, assess why the virus has preference for neurons upon secondary infection, and how the virus is able to do this. Insight into viral mechanisms generates new ways to attack the virus with anti viral drugs and even a vaccine. Although this study outlined and confirmed previous knowledge, I do not believe they did enough original work. Perhaps they should have further isolated the virus in neuronal tissues, such as the spinal cord and brain stem, to isolate viral proteins and attempted a subunit vaccine. The researchers successfully established that the virus was dose dependent and produced a persistent infection in the presence of MAV, but this model had already been done before. If they had attempted to inoculate some hamsters at birth ...
