Chronic Endometritis in Subfertile Mares With Presence of Chlamydial DNA

When endometritis becomes chronic in mares, infertility can follow. Among various causative agents, many bacteria are involved, and mono- or mixed-infections are common. In our study, 50 mares with a previous history of subfertility were subjected to clinical and ultrasonographic examination of the reproductive tract, and samples were collected for cytology, histology, bacteriology, and polymerase chain reaction for Chlamydia spp detection. The aim of this work was to highlight the presence of Chlamydia abortus in chronic endometritis of subfertile mares. Endometrial chronic lesions were detected in five of six Chlamydia-positive animals

Soft magnetic properties of high-temperature nanocrystalline alloys: Permeability and magnetoimpedance.

The technological applicability of FeCoNbBCu alloys is suggested in terms of measurements of room temperature magnetoimpedance and temperature dependence of magnetic permeability m r . Results for the Fe 78- x Co x Nb 6 B 15 Cu 1 alloy series show that room temperature soft magnetic properties are enhanced in the lowest Co containing alloy ( m r ; 10 500 and magnetoimpedance ratio ; 60% at 1 MHz ! . However, permeability exhibits a smoother thermal dependence in the alloys with medium and high Co content. A tradeoff between magnetic softness and its thermal stability reveals the alloy with 39 at. % Co as the most suitable composition among those studied, characterized by a temperature coefficient of ; 0.02%/K from room temperature up to 900 K. This value is 1 order of magnitude smaller than those observed for FeSiBCuNb ~ FINEMET-type ! alloys and Mn ferrites and extended over a much wider temperature range than in these materials

Hysteresis and Avalanches in the Random Anisotropy Ising Model

The behaviour of the Random Anisotropy Ising model at T=0 under local relaxation dynamics is studied. The model includes a dominant ferromagnetic interaction and assumes an infinite anisotropy at each site along local anisotropy axes which are randomly aligned. Two different random distributions of anisotropy axes have been studied. Both are characterized by a parameter that allows control of the degree of disorder in the system. By using numerical simulations we analyze the hysteresis loop properties and characterize the statistical distribution of avalanches occuring during the metastable evolution of the system driven by an external field. A disorder-induced critical point is found in which the hysteresis loop changes from displaying a typical ferromagnetic magnetization jump to a rather smooth loop exhibiting only tiny avalanches. The critical point is characterized by a set of critical exponents, which are consistent with the universal values proposed from the study of other simpler models.Comment: 40 pages, 21 figures, Accepted for publication in Phys.

Anatomo-pathological and forensic entomological exams for determining the burial time of swine carcasses in a criminal case

Post mortem evaluation of a number of swine carcasses, using anatomo-pathological exam, was compared to entomological analysis to determine the burial time. In the selected area of denounced land a series of random holes were dug. Carcasses were found in different stages of decomposition, and entomological material was also found with and around the rotten parts: that fauna was composed of Diptera and Coleoptera. Where there was only bone tissues remaining there was an absence of entomological reports. In one case by use of entomological samples it was possible to identify a vertical burial stratification. Anatomo-pathological analyses in veterinary medicine can make use of entomological evaluation as a useful tool to investigate the illegal disposal of carcasses

Monophasic teratoma of the ovarian remnant in a bitch

An exploratory laparotomy on a mixed-breed bitch of an estimated age of 5 years revealed that she had undergone ovariectomy in the past, but a cystic structure was present in the area of the right ovary and a whitish mass, approximately 3 cm in diameter, in the area of the left ovary. These structures were removed together with an apparently normal uterus. Histological examination of the cyst showed a thin layer of connective tissue, while the left ovarian mass revealed ovarian tissue and highly differentiated nervous tissue, confirmed through immunohistochemistry. A presumptive diagnosis of mature ovarian teratoma was made. Although teratomas generally contain recognizable elements from more than one of the three germ cell layers, they can also be monophasic, when there is only one germ layer component. Ovarian teratomas are rare in the dog and never before have been reported in an ovarian fragment.</br

Comparison between forensic entomological and anatomo-pathological exams to determine the burial time of swine carcasses in a fraudolent case

Post mortem evaluation for a number of death pigs was compared to entomological exams in order to determine the burial time. In the denounced land were made some holes in places choosen arbitrarily. Entomological material was found in areas with carcasses in colliquative rotten stage and the checked fauna was composed by Diptera and Coleoptera. Where there were only bony tissues remains we observed the absence of entomological reports. In one case by use of entomological exam was possible to identify a vertical burial stratification. The comparison between entomological evaluation and anatomo-pathological exam in veterinary medicine is a useful tool to investigate the illegal disposal of carcasses
