The establishment of a nitrogen-fixing root nodule on legumes requires the induction of mitotic activity of cortical cells leading to the formation of the nodule primordium and the infection process by which the bacteria enter this primordium. Several genes are up-regulated during these processes, among them ENOD40. Here it is shown, by using gene-specific(More)
PRIMARY OBJECTIVE Several studies have shown that the symptoms of grief are different from symptoms of depression among bereaved family members. The present study is an attempt to replicate these findings among caregivers of patients in a vegetative state. METHODS AND PROCEDURES Forty-five caregivers of 41 patients in vegetative or minimally conscious(More)
Death or severe invalidity (e.g. vegetative state) of a family member causes deep emotional distress to the caregiver. In most cases elaboration of mourning at the loss unfolds in physiological times and modes, enabling the caregiver to react to the separation and resume their own daily life. In some cases, however, there is an incapacity to react and(More)
Previous studies have shown that Prolonged Grief Disorder (PGD), Post-traumatic Stress Disorder (PTSD) and major depression are autonomous nosological entities. The present study aims at further analyzing the relationship among them in a sample of caregivers of patients in Vegetative State (VS) or Minimally Conscious State (MCS). We also investigated(More)
Disorders of consciousness (DOC) have been studied in recent years. In the present research, electrophysiological measures (ERPs) were used to verify the preservation of semantic linguistic processes in vegetative states (VS) and minimal-consciousness state (MCS). Eighteen patients classified as VS or MCS, and 20 controls were submitted to a semantic(More)
Echinacea angustifolia cell suspension cultures are usually grown and maintained in the dark, but we also exposed cells to light for one culture cycle (14 days) and then compared the metabolomes of dark-grown and illuminated cells by liquid chromatography–mass spectrometry. Among 256 signals, we putatively identified 159 molecules corresponding to 56(More)
With the notable advances made in all branches of medicine doctors are now increasingly faced with issues no longer of a purely clinical nature but of an ethical and moral nature. Chronic diseases, terminal conditions, and the vegetative state are just some of the many examples of clinical conditions that impose on health professionals the need to reflect(More)
The aim of this study was to evaluate the kinetics of arterial plasma amino acid profile during the first 48 h of clinical TPN in order to assess the time necessary to reach the steady-state condition during infusion. Each patient was treated with one of three different amino acid solutions yielding, in the same nitrogen intake, different intakes of(More)
The equilibrium kinetic of two different amino acid solutions was investigated in ten catabolic patients (Parentamin, Pierrel; HBC, Baxter). Plasma amino acid pattern was determined on arterial samples before TPN and several times over 48 hours of TPN. Nitrogen balance was measured from 24 hours urine collection. Three different cinetic trends were found: a(More)
Believed to be due to unbalance between cerebrospinal fluid (CSF) production rate and its loss through the spinal dural puncture hole, post-dural puncture headache (PDPH) is often considered as a physiological syndrome, usually reversible without pathological sequelae after dural hole's closure. The clinical case here presented (incapacitating headache(More)
