Prediction of intracellular storage polymers using quantitative image analysis ...

The present study focuses on predicting the concentration of intracellular storage polymers in enhanced biological phosphorus removal (EBPR) systems. For that purpose, quantitative image analysis techniques were developed for determining the intracellular concentrations of PHA (PHB and PHV) with Nile blue and glycogen with aniline blue staining. Partial least squares (PLS) were used to predict the standard anal...

Development of image analysis methodologies to quantify intracellular PHA, poly...

In wastewater treatment plants (WWTP), enhanced biological phosphorus removal (EBPR) processes are performed by mixed cultures containing polyphosphate (PAO) and glycogen accumulating organisms (GAO). In these processes, it is of crucial importance to monitor the intracellular metabolism, namely glycogen, polyhydroxyalkanoates (PHA) and polyphosphate (polyP) inclusions, to determine its efficiency. However, tra...

Intracellular poly-P assessment by DAPI staining and image analysis

In wastewater treatment, enhanced biological phosphorus removal (EBPR) is considered a well-established process to remove phosphate (P). EBPR is based on the activity of polyphosphate-accumulating organisms (PAOs) able to take up and store large amounts of P as intracellular (poly-P) granules. However, monitoring poly-P in mixed cultures is usually performed by a laborious and time consuming off-line chemical a...

MRI of Gastric Cancer: T and N Staging with Pathologic Correlation

Prediction of intracellular storage polymers using quantitative image analysis ...

Intracellular polymers, such as polyhydroxyalkanoates (PHA) synthesized by microorganisms for energy and carbon storage, can be commercially used as biodegradable plastics in a wide range of applications. The possibility of obtaining high PHA contents (where the most common monomers found are poly-hydroxybutyrate (PHB) and poly-hydroxyvalerate (PHV)) from inexpensive inocula and raw materials emerges as a promi...

A coupled convection-diffusion level set model for tracking epithelial cells in...

Colorectal cancer is initiated in colonic crypts as a consequence of alterations leading to the disruption of the normal colonic cellular process. We propose a model, which couples a convection-diffusion type equation with a level set equation, for tracking the time evolution of an epithelial cell set, inside a colonic crypt, until it reaches the top of the crypt. The convection-diffusion equation describes the...

Falha na sexagem por inibição do desenvolvimento de embriões bovinos produzidos...

Embriões bovinos produzidos in vitro, em estádio de mórula, foram cultivados em meio contendo anticorpos anti H-Y de alto título proveniente de ratos por 24h e, após este tempo, classificados em dois grupos: 1) embriões inibidos em estádio de mórula (classificados como machos) e 2) embriões que se desenvolveram e formaram a blastocele (classificados como fêmeas). O sexo de 311 embriões, distribuídos em três gru...

Perfil de susceptibilidade a antimicrobianos de bactérias isoladas em diferente...

Caracterizaram-se as populações bacterianas isoladas de três sistemas de cultivo de tilápias, sem utilização prévia de antimicrobianos. No sistema 1 usou-se tanque de alvenaria com arraçoamento, no sistema 2, tanque de terra com arraçoamento e no sistema 3, tanque de terra com adubação orgânica. Posteriormente, foi verificado o perfil qualitativo de resistência a antimicrobianos de 98 amostras bacterianas. Memb...
