Three-dimensional (3D) bioprinting is driving major innovations in the area of cartilage tissue engineering. Extrusion-based 3D bioprinting necessitates a phase change from a liquid bioink to a semi-solid crosslinked network achieved by a photo-initiated free radical polymerization reaction that is known to be cytotoxic. Therefore, the choice of the photocuring conditions has to be carefully addressed to generate a structure stiff enough to withstand the forces phisiologically applied on articular cartilage, while ensuring adequate cell survival for functional chondral repair...

BACKGROUND: Despite the fact that in recent years, a substantial progress has been made in the treatment of pulmonary hypertension, it is still a severe disease characterized by poor prognosis, and the search for new drugs remains a priority. Current remedies address mainly the vasoconstrictor/ vasodilator imbalance in the pulmonary circulation, while the causes of the disease are only moderately affected. Recently, the role of receptor and non receptor kinases in pulmonary hypertension has emerged and these targets were extensively considered for the development of new therapeutic strategies...

Phisiological activation of PI3K pathway is necessary for cells to regulate many different physiological processes such as transcription, protein synthesis, metabolic responses and membrane trafficking. Abnormal activation of the PI3K pathway leads to an increased activity resulting in tumor onset, maintenance, progression and invasion. Both genetic and epigenetic alterations could affect the normal pathway's activation. Ovarian cancer is the leading cause of death from gynaecological malignancies in the western world...

Measurements of multiple physiological signals are required for diagnostic procedures such as for sleep disordered breathing. Accuracy of automated diagnostic procedures and home based screening methods can be affected when phisiological measurements contains artifacts or signal losses. We investigate on predicting one physiological signal measurement from others, using dependencies exists in physiological signals, in order to obtain a measure of reliability to the measurements. Modeling such relationships are done with the use of artificial neural networks...

BACKGROUND: Soluble, human low affinity Fcgamma receptors, such as sFcgammaRII and sFcgammaRIII, are known to play a pathologic role in different diseases. Sandwich ELISAs had previously been applied for the specific detection and determination of these soluble receptors. In these ELISAs, commercial monoclonal antibodies (Ab) were used as capture antibodies with monoclonal or polyclonal antibodies serving as detector Abs. Increased levels of cell-free FcgammaRIII have been detected in patients with lupus but the functions and levels of sFcgammaRII have not been fully characterized yet...

We have studied the effect of ultracaine DS forte on local blood flow of the rat gum as well as on the development of the convulsion activity of the brain at systemic injection. Experiments were carried out on 12 mongrel albino mail rats of 200-250 g weight. In the I group of animals under the light chloral hydrate anesthesia we studied the changes of local blood flow in the rat gum of lower jaw after ultracaine DS forte injection (right side) and the similar quantity of phisiological solution (left side). According to our data, in the right gum, the rate of local blood flow decreases statistically significantly at 18%, while the injection of physiological solution did not result in any changes...

BACKGROUND: In concurrence of our recent findings of the elevation of QT dispersion (QTd) in the group of pregnant women, mathematical approaches were developed aimed to give possible geometrical explanation whether the observed changes result from the rotation or from the changed position of the heart. METHODS AND RESULTS: Mathematical model of the cardiac electrical field approximated as a time variable dipole in a homogenous spatial conductor was developed. From the experimental vectocardiographic records, representing time course of the cardiac dipole, body surface potential maps were calculated on the basis of the model...

The phorbol esters, such as phorbol 12- myristate 13-acetate (PMA), are known to be powerful tumor promoters and activators of protein kinase C (PKC). First discovered by Nishizuka et al., PKC is a phospholipid- and calcium-dependent serine/threonine kinase, phisiologically activated by 1,2-diacyl-sn-glycerol (DAG). PKC is also known to be an important target for other structurally diverse tumor promoters such as ingenols, teleocidins, and aplysiatoxins. Structure-activity analyses of a variety of analogs of DAG and these tumor promoters have been carried out...

In this paper the main question is about the health complete interpretation. It is an epistemological discussion. It starts with the obstacles in the comprehension from several sciences (i.e. phisiology, epidemiology, and sociology) about the health as a social and collective problem. The point is how to do the research and the conceptual interpretation. Finally, the authors explain theirs point of view: the most important is the nature and specificity of the objet health. Not view disciplinary. They show a model to understand the analysis of the health from the social sciences perspective...
