Among the new substances that were synthesised by the chemical industlY during the last decades, with the aim to improve human prosperity, some cause negative effects on non target organisms like fish. Among the pesticides, the organophosphates (OP) are widely used in cattle management, agriculture and aquaculture activi ties. Brachydania reria Hamilton-Buchman, 1822 is used world-wide in fisht...

Focal necrosis of cardiac and skeletal muscle was produced regularly in rabbits by means of a single intravenous or intra-arterial injection of a solution of crude papain. Similar lesions were produced in rats and mice injected with this material. The intravenous injection of solutions of ficin, trypsin, and streptokinase also resulted in comparable lesions of cardiac and skeletal muscle in rab...

A 56-year-old woman presented with a 2-year history of right hemispheric focal seizures confirmed by electroencephalography. Physical and neurologic examination revealed only a mild left-central facial nerve paresis. CT showed a cystic right parasagittal tumor with an enhancing wall (Fig. 1 A). The thin wall was of varied thickness but without focal nodularity. The cystic tumor abutted the falx...

AIM We describe a case of Aggressive Digital Papillary Adenocarcinoma, a rare skin neoplasm with acral location. RESULTS The patient, a 66 year old man, presented with an ulcerated mass of the fifth toe of the left foot, 4.4 cm in size. Histologically the tumour was characterized by a solid-cystic structure, with extensive papillary component, comedo necrosis and focal eccrine differentiation...

PURPOSE To investigate ocular involvement (prevalence, incidence, lesion characteristics) following postnatally acquired infection with an "atypical" genotype of Toxoplasma gondii during a well-characterized 2001 outbreak in Santa Isabel do Ivaí, Brazil, attributed to a contaminated municipal reservoir. DESIGN Prospective longitudinal cohort study. METHODS We performed ophthalmic examinatio...

BACKGROUND Cutaneous mast cell tumours are one of the most common neoplasms in dogs and show a highly variable biologic behaviour. Several prognosis tools have been proposed for canine mast cell tumours, including histological grading and cell proliferation markers. CD117 is a receptor tyrosine kinase thought to play a key role in human and canine mast cell neoplasms. Normal (membrane-associate...

BACKGROUND Gene therapy may be a promising approach for treatment of brain ischemia, although the efficiency of postischemic gene therapy is not established. Our goal in this study was to examine the effects of gene transfer of interleukin-10 (IL-10), an antiinflammatory cytokine, after induction of brain ischemia. METHODS AND RESULTS Brain ischemia was produced by either photochemical occlus...

BACKGROUND In Taiwan, cutaneous lesions with granulomatous lobular panniculitis, with or without vasculitis, are usually diagnosed as erythema induratum (EI), a common form of tuberculid associated with tuberculosis. However, there has been no study to elucidate the extent of this association in Taiwan. The aim of this study was to document the spectrum of the pathologic findings in EI and its ...

BACKGROUND Human brains show widespread necrosis when death occurs after coma due to cardiac arrest, but not after hypoxic coma. It is unclear whether hypoxia alone can cause brain damage without ischemia. The relationship of blood oxygenation and vascular occlusion to brain necrosis is also incompletely defined. METHODS We used physiologically monitored Wistar rats to explore the relationshi...

Differential diagnoses of hepatic nodules include hepatocellular carcinoma, focal nodular hyperplasia, hepatic adenoma, regenerative nodule, focal fatty changes, and hemangioma. However, differentiation of these nodules can often be difficult. Hemangiomas are frequently encountered during ultrasonogram incidentally and can be diagnosed easily because they have an almost distinctive sonographic ...
