    The physically effective neutral detergent fiber content alone has not been able to explain the appearance of diarrhea in ruminants fed diets with large volumes of spineless cactus, so the proliferation of enterobacteria in spineless cactus may be associated with cases of diarrhea in sheep. In the in vitro test, used two varieties of spineless cactus, both of which were chopped to particles of 4 and 2 cm2. For the in vivo test, 15 lambs were allocated to three treatment groups, namely, spineless cactus crushed and immediately supplied to the animals; spineless cactus crushed 8 h before supply; and silage of spineless cactus. The variables evaluated were dry matter intake, weight gain, fecal score, hemogram, and fecal colony count. In the in vitro test, higher Enterobacteriaceae and lactic acid bacteria counts were found both at 12 h and 24 h when the spineless cactus was crushed to 2 cm2 in both varieties. The sheep fed the spineless cactus crushed 8 h prior to supply showed the highest Enterobacteriaceae count in the feces (8.48 CFU/g), compared to animals fed silage of spineless cactus (4.95 CFU/g). It can thus be concluded that the management of spineless cactus influences the development of total and fecal coliforms, especially when it is chopped to 2 cm2 and exposed to the environment for periods longer than 7 h, and that the bacterial population can be controlled by administering the spineless cactus in the form of silage.The transient receptor potential melastatin 4 (TRPM4) is a Ca2+-activated nonselective monovalent cation channel belonging to the TRP channel superfamily. selleck chemicals TRPM4 is widely expressed in various tissues and most abundantly expressed in the heart. TRPM4 plays a critical role in cardiac conduction. Patients carrying a gain-of-function or loss-of-function mutation of TRPM4 display impaired cardiac conduction. Knockout or over-expression of TRPM4 in mice recapitulates conduction defects in patients. Moreover, recent studies have indicated that TRPM4 plays a role in hypertrophy and heart failure. Whereas the role of TRPM4 mediated by cardiac myocytes has been well investigated, little is known about TRPM4 and its role in cardiac fibroblasts. Here we show that in human left ventricular fibroblasts, TRPM4 exhibits typical Ca2+-activation characteristics, linear current-voltage (I-V) relation, and monovalent permeability. TRPM4 currents recorded in fibroblasts from heart failure patients (HF) are more than 2-fold bigger than those from control individuals (CTL). The enhanced functional TRPM4 in HF is not resulted from changed channel properties, as TRPM4 currents from both HF and CTL fibroblasts demonstrate similar sensitivity to intracellular calcium activation and extracellular 9-phenanthrol (9-phen) blockade. Consistent with enhanced TRPM4 activity, the protein level of TRPM4 is about 2-fold higher in HF than that of CTL hearts. Moreover, TRPM4 current in CTL fibroblasts is increased after 24 hours of TGFβ1 treatment, implying that TRPM4 in vivo may be upregulated by fibrogenesis promotor TGFβ1. The upregulated TRPM4 in HF fibroblasts suggests that TRPM4 may play a role in cardiac fibrogenesis under various pathological conditions.Cattle piroplasmoses are tick-borne diseases, spread worldwide that cause significant economic losses. A participatory epidemiological study was conducted individually or in focus groups with 73 cattle owners in Beni Hamidene locality (district of Constantine, Algeria). The aim of this study was to study cattle owners’ knowledge, attitude and perception on cattle piroplasmosis. Proportional piling technique was used to determinate most common cattle diseases, and to evaluate economic impact of diseases according to the interwieved farmers. Theileriosis (49/73; 67.1%) and babesiosis (44/73; 60.3%) were considered the most important bovine diseases. No zoonotic disease was cited by the interviewed cattle owners. According to the majority of cattle owners, theileriosis and babesiosis are deadly diseases (87.3 and 78.1%, respectively). All cattle owners (73/73) cited fever as the most common symptom of tropical theileriosis. Some of them (14/73; 19.2%) do not make distinction between theileriosis and babesiosis. According to cattle owners (65/73; 89.0%), the use of acaricide is the most appropriate tick control method. This study provides information about knowledge on bovine piroplasmoses in Algeria. These information could be considered when performing control programmes by both animal decision-makers and field veterinarians.

    In the authors’ department, anewly implemented clinical algorithm for application of perioperative thrombosis prophylaxis in head and neck surgery recommends restrictive handling of anticoagulants. This retrospective study aims to evaluate the algorithm by comparing incidences of venous thromboembolic events (VTE) and surgical revisions due to postoperative hemorrhage.

    Perioperative incidences of deep vein thrombosis and pulmonary embolism as well as surgical revisions due to postoperative hemorrhage after head and neck surgery were determined based on all patients operated in the department over aperiod of 36months. The incidences before (groupI) and after (groupII) implementation of the restrictive algorithm were compared.

    Atotal of 9276patients were included. The incidences of VTE (0.12%) and surgical revisions due to postoperative hemorrhage (1.4%) were low. Incidences of VTE were non-significantly higher in groupII (0.16%) than in groupI (0.08%; p > 0.45, chi-square-test). Case analysis revealed that this difference was not due to implementation of the restrictive algorithm. The incidence of surgical revision due to postoperative hemorrhage was identical in the two groups (1.4%).

    After restricting the indication for thrombosis prophylaxis, the incidence of VTE or surgical revision due to postoperative hemorrhage did not change significantly. The provided clinical algorithm represents a low-risk and low-cost strategy of perioperative risk stratification.
