The intestinal microbiota is the collection of the living microorganisms(bacteria, fungi, protozoa, and viruses) inhabiting the gastrointestinal tract. Novel bacterial identification approaches have revealed that the gastrointestinal microbiota of dogs and cats is, similarly to humans, a highly complex ecosystem. Studies in dogs and cats have demonstrated that acute and chronic gastrointestinal diseases, including inflammatory bowel disease(IBD), are associated with alterations in the small intestinal and fecal microbial communities. Of interest is that these alterations are generally similar to the dysbiosis observed in humans with IBD or animal models of intestinal inflammation, suggesting that microbial responses to inflammatory conditions of the gut are conserved across mammalian host types. Studies have also revealed possible underlying susceptibilities in the innate immune system of dogs and cats with IBD, which further demonstrate the intricate relationship between gut microbiota and host health. Commonly identified microbiome changes in IBD are decreases in bacterial groups within the phyla Firmicutes and Bacteroidetes, and increases within Proteobacteia. Furthermore, a reduction in the diversity of Clostridium clusters XIVa and IV(i.e., Lachnospiraceae and Clostridium coccoides subgroups) are associated with IBD, suggesting that these bacterial groups may play an important role in maintenance of gastrointestinal health. Future studies are warranted to evaluate the functional changes associated with intestinal dysbiosis in dogs and cats. 展开更多

[目的]了解自然条件下野外越冬前期异色瓢虫[Harmonia axyridis(Pallas)]体内超氧化物歧化酶(SOD)和过氧化氢酶(CAT)活性的变化情况。[方法]定期采集野外越冬前期的异色瓢虫,并通过紫外分光光度法测定其CAT和SOD活性。[结果]CAT和SOD活性变化与温度、相对湿度和昼长变化均无显著相关性;但2种酶活在11月2日之前均呈上升趋势,而后至12月7日呈上升或下降波动;CAT活性在11月16日达到最高峰,12月7日到达低谷;而SOD活性在11月2日和12月7日达到高峰,11月16日达到低谷,两者变化呈互补性。[结论]当温度低于4.8℃、昼长短于10.10 h时,异色瓢虫开始滞育;而温度达-9.0℃、昼长短于8.70 h时,绝大多数异色瓢虫滞育越冬;在上述2个滞育点期间,异色瓢虫体内CAT和SOD活性变化明显,其活性大小可作为异色瓢虫滞育越冬的标志。 展开更多

The aim of this work is to emphasize the importance of a differential diagnosis of von Brunn’s nests in cats from other urothelial neoplastic disorders, as transitional cell carcinoma, for a subsequent optimal care. Von Brunn’s nests and cysts are submucosal benign urothelial processes, related to irritative stimuli (calculi and urinary infections), characterized by an invagination with buds and clusters of normal urothelium in the lamina propria. They are common findings in the urinary bladder of human beings, but few cases have been described in dogs and cats. We report macroscopic, histopathological and, in one case, immunohistochemical features of these rare forms in the left ureters of two cats. Macroscopic evidence during surgery of ureteral nodules in two cats was accompanied by histopathological diagnosis and, in one case, by immunohistochemical assessment. Histopathology was coherent with a rare condition characterized by nests and islands of normal urothelium in the lamina propria and submucosa, with formation of cysts and moderate focal subacute inflammation. In one case epithelial cells of the nests showed well differentiated urothelial cells with an intense immunoreactivity to pan-cytokeratin (CK AE1/AE3), CK19 in the first outer layers, a slight immunoreactivity to CK20 and a low proliferative activity using MIB-1 (Ki67). 展开更多

A 3-year-old Persian queen was referred to Teaching Veterinary Hospital while 3 neonates' umbilical cords were entangled with the queen's tail hair.Close inspection of the cat showed that the umbilical cords of 3 kittens had twisted around together and entangled with the moms' hairs in the base of tail region.Also this complex has been warped around the left tarsus of one of the involved kittens and caused swelling and skin darkness in the involved limb.Operation was carried out urgently.After cutting the queen's involved hairs the kittens were released.Then the twisted umbilical cords and the hairs were isolated from the umbilical cord and the involved leg was released from the umbilical cords and the twisted umbilical cords were separated from each other.During one week follow up,dry gangrene occurred in the distal extremity of the injured limb and consequently,amputation was performed on the distal part of tibia.Our clinical findings suggest that long hair coats of queens could be a maternal life threatening factor for neonates' life. 展开更多

Infrared (IR) absorption spectra and X-ray powder diffraction (XRD) patterrns of sexpenfine cat's eye from Sichuan Province have been investigated, and infrared absorption bands of the serpentine have been assigned in this paper. The results indicate that the bands near 3 600 - 3 700 cm^-1 belong to the stretching absorption band VOH, the bands in 948 - 1 100 cm^-1 axe assigned to the stretching vibraling band Usvo, and the bands at 600 570 and 440 cm^-1 respectively belong to the bending vibration band VOH, δMg-O and δSi-O. The serpentine cat' s eye includes two types: chrysotile and antigorite. Chrysotile has a sharp and intensive band at 3 688 cm^-1 and a weak band at 3 643 cm^-1 , while antigorite has only one intensive band in the region. At vibration band VSi-O, chrysotile and antigorite have a similar feature at 1 071 cm^-1, but the band at 980 cm^-1 in anfigorite has been split into two bands in chrysotile - a strong one at 1 027 cm^-1 and a weak one at 949 cm^-1. In addition, antigorite has a characteristic bending vibrating band δMg-O at 570 cm^-1. Based on the analysis of the feature of crystal structure, their IR differences axe well explained. 展开更多

In his famous thought experiment, Schr?dinger (1935) imagined a cat that measures the value of a quantum mechanical observable with its life. Since Schr?dinger’s time, no any interpretations or modifications of quantum mechanics have been proposed which give clear unambiguous answers to the questions posed by Schr?dinger’s cat of how long superpositions last and when (or whether) they collapse? In this paper appropriate modification of quantum mechanics is proposed. We claim that canonical interpretation of the wave function is correct only when the supports of the wave functions and essentially overlap. When the wave functions and have separated supports (as in the case of the experiment that we are considering in this paper) we claim that canonical interpretation of the wave function is no longer valid for a such cat state. Possible solution of the Schr?dinger’s cat paradox is considered. We pointed out that the collapsed state of the cat always shows definite and predictable outcomes even if cat also consists of a superposition: . 展开更多

Natsume Sōseki(1867-1916) suffered from cyclic mental depressions through his life, and it was when he was in the state of the most terrible one that he started his career as a writer by writing I Am a Cat(1905-1906). There are some evidence by his wife and friends that Sōseki's condition of disease dramatically improved during its serialization on a magazine, and the writer himself admited humorously in the preface of other work that it was his depression and mania that enabled him to produce I Am a Cat and other early works. This paper aims at describing the process how his act of narrating had therapeutic effects on his state of mind focusing on the construction of complicitous relationship between an implied author and readers in the work by the unique functions of the first-‘person' narrator: A Cat. Among others, I will consider the influence of Laurence Sterne's Tristram Shandy(1759-1767), which Sōseki introduced to Japan for the first time, by discussing the frequent use of metalepsis that the two works have in common. 展开更多
