Objective(s): Haemostasis prevents blood loss following vascular injury. It depends on the unique concert of events involving platelets and specific blood proteins, known as coagulation factors. The clotting system requires precise regulation and coordinated reactions to maintain the integrity of the vasculature. Clotting insufficiency mostly occurs due to genetically inherited coagulation fact...

the evaluation of plaque and tooth decay represents the oral health status of society. lack of oral hygiene, can adversely affect the health of students. this study was designed with the aim to determine the oral- dental health status of the first grade guidance students in hamadan: using health belief model (hbm). this was a descriptive- analytical study which was conducted on 268 students of ...

prediction of spatial and temporal variation of water quality is vital for managing pollutantsdisposal into the rivers. depletion of dissolved oxygen (do) takes place due to the consumption of oxygen bymicrobes to digest bio-degradable pollutants which enter a water course. reaeration takes place in a specificrate depending on do deficit. many investigators have formulated models as an alternat...

Measuring the natural resistance of wood is fundamental for proper use. The durability five tropical species was investigated by field decay testing during exposure 360 days. Wood logs (length 0,5 m; diameter 8 cm - 12 cm) were used in this study. mass loss and index calculated visual analysis time performed all samples. samples presented evidence two different groups concerning durability. fir...

AIMS To evaluate the persistence of Mycobacterium avium subsp paratuberculosis (Myco. paratuberculosis), Salmonella enterica serotype Typhimurium (Salm.Typhimurium) and a commensal Escherichia coli (E. coli) isolate under the low pH and high organic acid (OA) conditions of ensiling of forages. METHODS AND RESULTS Decay rates and the time required to obtain a 90% reduction in cell concentratio...

New antibacterial strategies are required in view of the increasing resistance of bacteria to antibiotics. One promising technique involves the photodynamic inactivation of bacteria. Upon exposure to light, a photosensitizer in bacteria can generate singlet oxygen, which oxidizes proteins or lipids, leading to bacteria death. To elucidate the oxidative processes that occur during killing of bac...

Subplate neurons play an important role in early cortical development. To investigate whether these transient neurons receive synaptic inputs, we performed whole-cell recordings from visually identified and biocytin-labeled subplate cells in somatosensory cortical slices from postnatal day 0-3 rats. Subplate neurons had an average resting membrane potential of -55 mV and input resistance of app...

The aim of the present study was to combat wood decay based on the approach controlled-release biocides from polymers. The possibility of introducing polymer-bonded fungicides into the cell lumens was investigated. The synthesis of ethylene maleic anhydride copolymer con­ taining pentachlorophenol (penta) and 8-hydroxy quino­ line (8HQ) in N, N dimethyl formamide is described. It was demonstrat...
