SINDROME DA ATTIVAZIONE MACROFAGICA SECONDARIA AD IMMUNODEFICIT

2018

Introduzione: la sindrome da attivazione macrofagica (SAM) è una condizione clinica rara, di cui esistono forme primitive (es. deficit di perforine) e secondarie ad infezioni, farmaci, immunodeficit; nel 10% dei casi rappresenta una complicanza dell'artrite idiopatica giovanile sistemica (AIG). Criteri diagnostici: febbre, epatosplenomegalia, citopenia bilineare, aumento di ferritina, transaminasi, ipertrigliceridemia ed ipofibrinogenemia con segni di emofagocitosi all'aspirato midollare. Terapia: metilprednisolone a 30 mg/Kg/die ev e terapia della patologia di base; nei no-responders trova impiego l'uso dei farmaci immunosoppressori come ciclosporina, Anakinra per forme secondarie ad AIG, …

Mannitol-producing tobacco exposed to varying levels of water, light, temperature and paraquat

2007

Transgenic mannitol-producing (+mtlD) and wild-type (-mtlD) tobacco plants were exposed to water deficit, varying light intensities, low temperatures, and paraquat applications to test whether mannitol was involved in protection against abiotic stresses. In the water deficit experiment, -mtlD and +mtlD plants were fully irrigated [100% evapotranspiration (ET)] or received 25% ET for 40 d. Water deficit reduced the relative water content (RWC) of both types of plant starting on day 22 and the total stem length (TSL) of -mtlD 25% ET plants after 11 d, whereas TSL of +mtlD 25% ET was reduced only after 34 d. After 30 days of water deficit, a higher percentage of mature foliage was retained by …

Transpiration and Water Use of an Irrigated Traditional Olive Grove with Sap-Flow Observations and the FAO56 Dual Crop Coefficient Approach

2021

The SIMDualKc model was applied to evaluate the crop water use and the crop coefficient (Kc) of an irrigated olive grove (Olea europaea L.) located in Sicily, Italy, using experimental data collected from two crop seasons. The model applies the FAO56 dual Kc approach to compute the actual crop evapotranspiration (ETc act) and its components, i.e., the actual tree transpiration (Tc act), obtained through the basal crop coefficient (Kcb), and soil evaporation according to an evaporation coefficient (Ke). Model calibration was performed by minimizing the difference between the predicted Tc act and the observed daily tree transpiration measured with sap flow instrumentation (TSF field) acquired…

SINGLE-TRIAL BASED INDEPENDENT COMPONENT ANALYSIS ON MISMATCH NEGATIVITY IN CHILDREN

2010

Independent component analysis (ICA) does not follow the superposition rule. This motivates us to study a negative event-related potential — mismatch negativity (MMN) estimated by the single-trial based ICA (sICA) and averaged trace based ICA (aICA), respectively. To sICA, an optimal digital filter (ODF) was used to remove low-frequency noise. As a result, this study demonstrates that the performance of the sICA+ODF and aICA could be different. Moreover, MMN under sICA+ODF fits better with the theoretical expectation, i.e., larger deviant elicits larger MMN peak amplitude.

Cognitive dysfunction in patients with relapsing-remitting multiple sclerosis

2006

Cognitive dysfunction is considered one of the clinical markers of multiple sclerosis (MS). However, in the literature there are inconsistent reports on the prevalence of cognitive dysfunction, and separate data for the relapsing-remitting (RR) type of the disease are not always presented. In this study, we submitted 461 RRMS patients to a battery of neuropsychological tests to investigate their impairment in various cognitive domains. As a consequence of the exclusion criteria, the sample is not fully representative of the entire population of RRMS patients. In this selected sample, when only the eight scores of a core battery (Mental Deterioration Battery) were considered (with respectiv…

Emotional interference and attentional processing in premenstrual syndrome

2017

Abstract Background and objectives Premenstrual syndrome (PMS) is characterized by menstrual cycle-related affective, behavioral, and/or somatic symptoms. By applying the emotional Stroop task (EST) the current study examined if changes in processing emotional information, which have been demonstrated in affective disorders, are also present in PMS. Methods Via online screening, telephone interviews, and daily records over two months 55 women for the PMS group (on the basis of the specific inclusion criteria and a prospectively confirmed PMS) and 55 ‘non-PMS’ controls were recruited. All participants completed three emotional Stroop tasks (EST) with neutral and negative word, picture, and f…

Neurochemical alterations in women with borderline personality disorder and comorbid attention-deficit hyperactivity disorder

2010

Borderline personality disorder (BPD) is associated with structural and functional brain changes. Recent models and findings refer to alterations of glutamate and total N-acetylaspartate (tNAA) in this condition.Absolute quantities of tNAA, creatine, glutamate, glutamine, myoinositol and total choline were measured using 3 Tesla magnetic resonance spectroscopy of the left anterior cingulate cortex and the left cerebellum in 14 unmedicated women with BPD and comorbid attention-deficit hyperactivity disorder (ADHD) and 18 healthy women. Both groups were matched with respect to age, education and premorbid intelligence.In the anterior cingulate, we found significantly higher tNAA and glutamate…

Effects of immunosuppressive drugs on the cognitive functioning of renal transplant recipients: A pilot study

2011

Some renal transplant patients show cognitive, emotional, and behavioral changes as part of possible neurotoxic effects associated with immunosuppressive medication, especially tacrolimus. This study evaluated effects of immunosuppressive drugs on some cognitive tasks. Patients treated with sirolimus and cyclosporine reported some of the noncognitive side effects related to immunosuppressive treatment. We observed attention and working memory impairment in patients treated with sirolimus or tacrolimus. Performance of cyclosporine-treated subjects was similar to that of healthy volunteer controls. Since the mood, anxiety, and sleep patterns measured were unaffected, it could be concluded tha…

Disturbed brain activation during a working memory task in drug-naive adult patients with ADHD.

2010

Neuroimaging studies in attention-deficit/hyperactivity disorder (ADHD) have shown abnormalities in several brain areas including the frontostriatal circuitry and were mostly conducted in children and adolescents. We investigated 30 never-medicated adult ADHD patients (16 males) and 30 matched healthy control individuals. Functional magnetic resonance imaging was acquired during a working memory paradigm (n-back). Group activation maps and group differences of activation were calculated using voxel-based analyses. The generic activation pattern was more extended in the control group. In ADHD patients, significantly decreased activation was found in the right inferior parietal cortex. Distur…
