| The goal of this study was to determine the symptoms and microscopic damage caused by fluoride on Spondias dulcis, a fluoride-sensitive species. The plants were exposed to simulated fog with fluoride (0, 5, 10, 15 and 20 mg L-1) for 20 min daily during four consecutive days. Samples from leaflets without any apparent fluoride injury were collected to microscopic analysis. The percentage of necrosed leaf area was measured, and the level of pollutant in the dry matter from the basal and apical portions of the plant was determined. The necroses began 24 h after the first simulation mainly from the base of the leaflets. A higher level of necrosis was observed at the apical portion of the plants, a region of higher fluoride accumulation. The damage on the... |

| ABSTRACT Papain is a proteolytic enzyme removed from the leaves of green papaya and/or latex. This enzyme is widely known as a medicinal fruit used extensively in human medicine for the treatment of wounds of various etiologies. However, studies and reports in veterinary medicine are scarce. Another herbal drug widely used in wound healing is Sunflower oil (Helianthus annus). It has inflammatory and antimicrobial properties which stimulate the local neovascularization, promoting tissue granulation, cell migration, fibroblast proliferation, and differentiation. Three dogs were treated with infected necrosis wounds, considered large, extent, and severe, with varied etiology. All cases were treated with papain gel with the exception of one dog, which was... |

| We investigated the effects of prolonged heat shock treatment on human embryonic stem cell (hESC) viability. The hESC viability steadily declined with longer exposure to heat shock treatment (43ºC). After 4 h of exposure to heat shock at 43ºC, only 56.2 ± 1.5% of cells were viable. Viability subsequently declined to 37.0 ± 3.3% and 3.5 ± 0.7% after 8 h and 16 h, respectively of heat shock treatment at 43ºC. Transmission electron micrographs showed that the morphology of the dead/dying cells after heat shock treatment was characteristic of cellular necrosis with an uncondensed chromatin and a non-intact plasma membrane. This was further confirmed by flow cytometry analysis which showed that the DNA of the dead/ dying cells was still mostly intact, unlike... |

| Cell death is preceded by severe disruption of inorganic ion homeostasis. Seconds to minutes after an injury, calcium, protons, sodium, potassium and chloride are exchanged between the cell and its environment. Simultaneously, ions are shifted between membrane compartments inside the cell, whereby mitochondria and endoplasmic reticulum play a crucial role. Depending of the type and severity of injury, two mutually exclusive metastable states can be reached, which predict the final outcome. Cells characterized by large increases in cytosolic [Ca2+], [Na+]; and [Mg2+] swell and die by necrosis; alternatively, cells characterized by high [H+]and low [K+], with normal [Na+] and normal to moderate [Ca2+] increases die by apoptosis. The levels of these ions... |

| El chile CM334 ha destacado por su alto grado de resistencia a la marchitez inducida por Phytophthora capsici la cual se manifiesta por una reacción de hipersensibilidad (RH), un tipo de muerte celular programada. Sin embargo, este genotipo es susceptible a otros fitopatógenos como Fusarium oxysporum y Nacobbus aberrans que también atacan a la raíz de la planta. El objetivo de este trabajo fue comparar los cambios morfológicos a nivel celular de las plantas de chile CM334 en la RH inducida por P. capsici (interacción incompatible) y la necrosis inducida por F. oxysporum (interacción compatible). Los tratamientos evaluados fueron CM334-P. capsici, CM334-F. oxysporum, CM334-Testigo, Yolo Wonder-P. capsici (control susceptible) y Yolo Wonder-Testigo. El... |

| An epidemiological survey was conducted in the Seine estuary and in two smaller and relatively preserved estuaries on the French Atlantic coast in order to estimate the occurrence of liver lesions in European flounder, Platichthys flesus, and also to seek putative risk factors for the recorded pathologies. Four hundred and seventy-eight fish of both sexes and of different size ranges were sampled in the three studied areas, 338 of which in the Seine estuary. All fish were examined for histopathological liver lesions, while DNA adducts and otoliths were analyzed on a subsample. Five categories of hepatic lesions were recorded with the following prevalence for the Seine estuary: 36.7 % inflammations, 8 % parasites (mainly encysted nematodes), 6.5 % foci of... |

| Recently, Manila clam, Ruditapes philippinarum, populations have suffered mortalities in Arcachon Bay (SW France). Mortality was associated with extensive lesions of the posterior adductor muscle, which become progressively brown and calcified. Ultrastructural observations by transmission electron microscopy revealed tissue degradation with necrotized muscle fibres and granulocytomas. Unenveloped virus-like particles (VLPs) were detected in muscle, granulocytic, epithelial and rectal cells. VLPs were abundant in the extracellular space, in the cytoplasm (free or enclosed in vesicles) and in the nucleoplasm of granulocytes. Nuclei and mitochondria of granulocytes displayed changes which suggested reactive oxygen species production and apoptosis induction.... |

| Tetrachloroethylene, a chlorinated solvent, is detected in the plume of East-Toulon domestic wastes treatment plant. Its subletal toxicity was tested du ring 31 days in a flow-through system at Pen Bron aquaculture centre, using swampshrimp Palaemonetes varians as test organism. Under expérimental conditions : natural variations in temperature and salinity , normal pH, ammonia and dissolved oxyg~n values, running tetrachloroethylene concentrations (10, 100 and 500 µg.l-1) induced neither mortalities nor any change in molting frequencies of experirnented animaIs. Histology of gills in contaminated animaIs showed several non specific deteriorations which could be observed either in control or assay animaIs. Necrosis levels nevertheless, seem to increase in... |

| Carbonated water is a fundamental part of many drinks and its effects have been studied in many pathological situations. However, cells and tissue damage as a consequence of carbonated water has not been the subject of extensive research. We assessed the short-term effects of soda on in vitro Hanging-drop culture of myoblasts and ex vivo lower limb of 8-day-old chicken embryo skeletal muscle tissue. Several groupswerendesigned: a) Control (Con-tyr), b) Carbonated water (Car), c) Coffe (Caf), and d) Cola beverage (Glu). The samples were observed with light microscopy and digital imaging analysis was performed. The ultra-structure of control and treated tissue were observed with electron microscopy. Immunohistochemistry techniques, such as terminal... |

| Peroxisomicine A1 (PA1), one of the toxins isolated from seeds of plants of the Karwinskia genus, whose targets organs are the liver, kidney, and lungs. There is a selective toxicity in vitro to cancer-cell lines derived from the lungs, liver, and colon, compared to normal cell lines. PA1 caused apoptosis in several cancer-cell lines in culture. In toxic doses to rodents, it causes extensive apoptosis in the liver, kidney, and lungs. In our study we were interested in evaluating, for the first time, the morphological effects of administration of PA1 to implanted TC-1 cells and in the target organs in vivo. The TC-1 cells were cultured and injected into the hind limb of C57BL-6 mice. The animals were divided into 3 groups; those treated with four doses of 1... |

| The authors report a case of bothropic envenoming in a male Cocker Spaniel. The animal was bitten in the ventral thoracic region, receiving treatment 4 hours later. Clinical examination revealed an extensive, painful and area of firm edema, absence of local or systemic hemorrhage, without evident neurological alterations. Clinical diagnosis was mild bothropic envenoming. Treatment consisted of 5 vials of polyvalent snake antivenom, two vials administered intravenously and three subcutaneously. Blood clotting time was always within normal values. Two days after envenoming, the animal showed hyperthermia and received enrofloxacin (5mg/kg/24h) for 10 days and ketoprofen (1mg/kg/24h) for 5 days. Seventy-two hours after envenoming, extensive subcutaneous,... |

| Background Asian slow lorises (Nycticebus spp.) are one of few known venomous mammals, yet until now only one published case report has documented the impact of their venomous bite on humans. We describe the reaction of a patient to the bite of a subadult Nycticebus kayan, which occurred in the Mulu District of Sarawak in 2012.Findings Within minutes of the bite, the patient experienced paraesthesia in the right side of the jaw, ear and right foot. By 40 minutes, swelling of the face was pronounced. The patient was admitted to Mulu National Park Health Clinic/Klinik Kesihatan Taman Mulu Tarikh, at which time he was experiencing: swollen mouth, chest pain, mild abdominal pain, nausea, numbness of the lips and mouth, shortness of breath, weakness, agitation... |
