Abstract
In this study, effects of LA-GPE (R-α-Lipoyl-Gly-l-Pro-l-Glu dimethyl ester) and GPE (Gly-L-Pro-L-Glu) on the cytotoxic action of Aβ1-42 were tested with differentiated human neuroblastoma SH-SY5Y cells as cellular Alzheimer model via measurements of mitochondrial viability (MTT assay) and lactate dehydrogenase release (LDH assay). Effects of LA-GPE and GPE on acetylcholinesterase (AChE) activity, total antioxidant capacity (TAC) and total oxidative status (TOS) levels, and neural cell apoptosis and necrosis were also determined. In addition, biological safety of these novel formulations was evaluated in human blood cells using different cytotoxicity and genotoxicity assays. Our results indicated that both compounds could block Aβ1-42 induced cell death. LA-GPE reduced Aβ-induced AChE activity and oxidative stress, suggesting it as a multifunctional compound potentially valuable for the treatment of Alzheimer's disease (AD).

Abstract
INTRODUCTION Oxidative stress, alpha-synuclein changes, mitochondrial complex I defects and dopamine loss, observed in the striatum of rats exposed to the pesticide permethrin in early life, could represent neuropathological hallmarks of Parkinson's disease (PD). Nevertheless, an animal model of PD should also fulfill criteria of face and predictive validities. This study was designed to: 1) verify dopaminergic status in the striatum and substantia nigra pars compacta; 2) recognize non-motor symptoms; 3) investigate the time-course development of motor disabilities; 4) assess L-Dopa effectiveness on motor symptoms in rats previously exposed to permethrin in early life. METHODS The permethrin-treated group received 34mg/kg daily of permethrin from postnatal day 6 to 21, whereas the age-matched control group was administered with the vehicle only. RESULTS At adolescent age, the permethrin-treated group showed decreased levels of dopamine in the striatum, loss of dopaminergic neurons in the substantia nigra pars compacta and cognitive impairments. Motor coordination defects appeared at adult age (150days old) in permethrin-treated rats on rotarod and beam walking tasks, whereas no differences between the treated and control groups were detected on the foot print task. Predictive validity was evaluated by testing the ability of L-Dopa (5, 10 or 15mg/kg, os) to restore the postural instability in permethrin-treated rats (150days old) tested in a beam walking task. The results revealed full reversal of motor deficits starting from 10mg/kg of L-Dopa. DISCUSSION The overall results indicate that this animal model replicates the progressive, time-dependent nature of the neurodegenerative process in Parkinson's disease.

Abstract
INTRODUCTION The failure of many molecules as CNS bioactive compounds is due to many restrictions: poor water solubility, intestinal absorption, in vivo stability, bioavailability, therapeutic effectiveness, side effects, plasma fluctuations, and difficulty crossing physiological barriers, like the brain blood barrier (BBB), to deliver the drug directly to the site of action. AREA COVERED Nanotechnology-based approaches with the employment of liposomes, micelles, dendrimers, and solid lipid nanoparticles (SLN) as drug delivery systems, are used to overcome the above reported limitations. Here, we focus on the delivery of drugs based on SLN formulation to treat neurodegenerative diseases. Notably, SLN have the ability to protect drugs from chemical and enzymatic degradation, direct the active compound towards the target site with a substantial reduction of toxicity for the adjacent tissues, and pass physiological barriers increasing bioavailability without resorting to high dosage forms. EXPERT OPINION We believe that SLN could represent a suitable tool to pass the BBB and permit drugs to reach damaged areas of the CNS in patients affected by neurodegenerative pathologies, such as Alzheimer's and Parkinson's diseases.

Abstract
In a previous work we reported the antiproliferative effects of (±)-MRJF4, a novel haloperidol metabolite II (HP-mII) (a sigma-1 antagonist and sigma-2 agonist) prodrug, obtained through conjugation to 4-phenylbutyric acid (PhBA) [a histone deacetylase inhibitor (HDACi)] via an ester bond. As a continuation of this work, here we report the asymmetric synthesis of compounds (R)-(+)-MRJF4 and (S)-(-)-MRJF4 and the evaluation of their biological activity on rat C6 glioma cells, derived from glioblastoma multiforme (GBM), which is the most common and deadliest central nervous system (CNS) invasive malignancy. Favourable physicochemical properties, high permeability in the parallel artificial membrane permeability assay (PAMPA), good enzymatic and chemical stability, in vivo anticancer activity, associated with the capacity to reduce cell viability and to increase cell death by apoptosis, render compound (R)-(+)-MRJF4 a promising candidate for the development of a useful therapeutic for gliomas therapy.

Abstract
A positive effect of estrogen treatment has been observed in neurodegenerative diseases such as Parkinson's disease. Since 17β-estradiol can modulate positively dopaminergic system, here we sought to evaluate the effect of 17β-estradiol supplementation on an animal model developing dopaminergic alterations on nucleus of striatum after neonatal exposure to permethrin pesticide. The goal of the study was to verify if the co-treatment with 17β-estradiol could protect against the damage induced by pesticide exposure in early life. Permethrin treated rats showed a decrease of dopamine and Nurr1 gene expression in striatum, while a more pronounced decrease of dopamine was observed in rats co-administered with permethrin+17β-estradiol. No difference between control and permethrin treated rats was observed in both mRNA of ERα and ERβ, whereas the rats co-administered with permethrin+17β-estradiol showed a down-regulation of ERα expression. The in vitro studies showed that permethrin, at high concentration may have an antagonist effect on ERα and even more pronounced in ERβ, thus suggesting that permethrin may block the estrogen neuroprotective effects. In conclusion, in male rats, the administration of estrogen further enhanced the impairment of dopaminergic transmission due to exposure to permethrin.

Abstract
Dopamine (DA) receptor (DR) type 1 (D1R) has been found to be expressed in luteal cells of various species, but the intrinsic role of the DA/DRs system on corpora lutea (CL) function is still unclear. Experiments were devised to characterize the expression of DR types and the presence of DA, as well as the in vitro effects of DA on hormone productions by CL in pseudopregnant rabbits. Immunoreactivity and gene expression for D1R decreased while that for D3R increased in luteal and blood vessel cells from early to late pseudopregnant stages. DA immunopositivity was evidenced only in luteal cells. The DA and D1R agonist increased in vitro release of progesterone and prostaglandin E2 (PGE2) by early CL, whereas the DA and D3R agonist decreased progesterone and increased PGF2α in vitro release by mid- and late CL. These results provide evidence that the DA/DR system exerts a dual modulatory function in the lifespan of CL: the DA/D1R is luteotropic while the DA/D3R is luteolytic. The present data shed new light on the physiological mechanisms regulating luteal activity that might improve our ability to optimize reproductive efficiency in mammal species, including humans.

Abstract
During the school years 2009-2010 and 2010-2011 a total of 25 cases of Non Tuberculous Cutaneous Mycobacteriosis (NTCM) were notified in children attending the same school with a swimming pool in Rome. Environmental microbiological and epidemiological investigations (only for suspected outbreaks in 2009-2010) were conducted. We screened students with skin lesions, and environmental samples were collected from the school area and the swimming pool. During the school year 2009-10 18 cases were clinically identified among 514 primary school children (3.50%) and all cases attended the swimming pool. Only 2 out of 18 cultures were positive for Mycobacterium chelonae complex (Group III, M. abscessus). Attack Rate for swimming pool use was 13,10% (17/130), with a Relative Risk 54,70 (95% CI: 9,4 - ∞). In February 2011 additional 7 cases of cutaneous NTM among children - who attended the same primary school and swimming pool were notified to the local public health authority followed by environmental microbiological investigation. Environmental samples were positive for NTM but not for M. abscessus. Mycobacteria are not included in water-quality criteria in Italy for this reason it is important to collect evidences of NTM cases caused by these infrequent pathogens, to be able to perform rapid risk assessment and to identify the best practices in prevention and management of such a risk.

Abstract
Metal-ion dysregulation and oxidative stress have been linked to the progressive neurological decline associated with neurodegenerative disorders such as Alzheimer's and Parkinson's diseases. Herein we report the synthesis and chelating, antioxidant, and in vitro neuroprotective activities of a novel derivative of glutathione, GS(HQ)H, endowed with an 8-hydroxyquinoline group as a metal-chelating moiety. In vitro results showed that GS(HQ)H may be stable enough to be absorbed unmodified and arrive intact to the blood-brain barrier, that it may be able to remove Cu(II) and Zn(II) from the Aβ peptide without causing any copper or zinc depletion in vivo, and that it protects SHSY-5Y human neuroblastoma cells against H2 O2 - and 6-OHDA-induced damage. Together, these findings suggest that GS(HQ)H could be a potential neuroprotective agent for the treatment of neurodegenerative diseases in which a lack of metal homeostasis has been reported as a key factor.

Abstract
Alzheimer's disease (AD) is characterized by irreversible and progressive loss of memory and cognition and profound neuronal loss. Current therapeutic strategies for the treatment of AD have been directed to a variety of targets with the aim of reversing or preventing the disease but, unfortunately, the available treatments often produce no significant clinical benefits. During the last decades compounds that inhibit or modulate γ-secretase, reducing β amyloid (Aβ) levels, have been considered as potential therapeutics for AD. Among these the (R)-enantiomer of flurbiprofen (FLU) seems to be very promising, but it shows low brain penetration. In this study, in order to improve the properties of FLU against Alzheimer's pathogenesis we synthesized some novel FLU lipophilic analogues. Lipophilicity of the new molecules has been characterized in terms of clogP, log K(C18/W) and log K(IAM/W) values. Permeability has been determined in both gastrointestinal PAMPA (PAMPA-GI) at different pH values and in brain blood barrier PAMPA (PAMPA-BBB) models. They were also tested for their ability to inhibit in vitro γ-secretase activity using rat CTXTNA2 astrocytes. Interestingly, the investigated molecules demonstrated to reduce Aβ 42 levels without affecting the amyloid precursor protein APP level in a clear concentrations-dependent manner.

Abstract
This study was performed to characterize and quantify mould and yeast isolates in fresh vegetables (FV) and ready to eat salads (RTES). During 2007, a random set of 194 samples, including 56 samples of FV and 138 samples of RTES, were analyzed for a total of 388 mycological determinations. Yeasts and moulds identification was carried out on 18/56 whole FV and 42/138 RTES. Yeasts were the predominant organisms in the FV (mean values: 6.20 log cfu g-1-8.00 log cfu g-) while moulds showed lower mean values (4.70 log cfu g-l-6.79 log cfu g-l). After processing, FV samples showed a statistically significant decreases (p-value <0.001) in the contamination of fungi. Most of the species identified were found both in the FV and RTES samples. Many of moulds species isolated belong to toxigenic genera Penicillium, Stachybotrys, Phoma, Fusarium indicating a potential mycotoxin production and a potential risk for consumers.

Abstract
Alzheimer's disease (AD) is the most common type of senile dementia, characterized by cognitive deficits related to degeneration of cholinergic neurons. The first anti-Alzheimer drugs approved by the Food and Drug Administration were the cholinesterase inhibitors (ChEIs), which are capable of improving cholinergic neurotransmission by inhibiting acetylcholinesterase. The most common ChEIs used to treat cognitive symptoms in mild to moderate AD are rivastigmine, galantamine, and donepezil. In particular, the lattermost drug has been widely used to treat AD patients worldwide because it is significantly less hepatotoxic and better tolerated than its predecessor, tetrahydroaminoacridine. It also demonstrates high selectivity towards acetylcholinesterase inhibition and has a long duration of action. The formulations available for donepezil are immediate release (5 or 10 mg), sustained release (23 mg), and orally disintegrating (5 or 10 mg) tablets, all of which are intended for oral-route administration. Since the oral donepezil therapy is associated with adverse events in the gastrointestinal system and in plasma fluctuations, an alternative route of administration, such as the transdermal one, has been recently attempted. The goal of this paper is to provide a critical overview of AD therapy with donepezil, focusing particularly on the advantages of the transdermal over the oral route of administration.

Abstract
Research on quality of surface waters has been performed also in Italy during the development of the large urban areas, and in Rome this has been the duty of the Istituto di Igiene of the Sapienza University since 1890. Using MedLine--and also traditional consultation for papers printed before 1968--we identified 100 articles printed in the period 1890-2010. Thirty of them met the inclusion criteria (to have been written by researchers belonging to the Rome universities and to contain microbiological informations about the surface waters of Rome). The majority of papers identified (46.6%) were produced during the years Sixties and Seventies of the 20th century, and 30% in the twenty years to follow (1980-1999). The most frequent microbiological descriptors were "Total coliforms" and "Streptococci". The waterbodies most investigated were the Tiber river and the coastal waters around Fiumicino, where the Tiber flows into the Tyrrhenian sea. The quality of surface waters has always been a central interest of the research performed by the Hygienists of the Roman School. The good quality of the past research and the renovated interest of International Organizations and of the European Union should encourage the public health researchers toward a strategic field of investigation which has strong interconnections with the protection of the individual and community health and also with the protection of the environment.

Abstract
BACKGROUND Although environmental and genetic factors may contribute to the etiology of blepharospasm, their relative contribution in causing familial and sporadic blepharospasm is unknown. METHODS First-degree relatives of 122 patients with primary blepharospasm were examined with a validated 2-step diagnostic procedure, including a screening questionnaire and examination of some relatives. Examiners were blinded to the questionnaire data for family history of probands. Data for demographic and clinical features, prior ophthalmologic complaints, and nondecaffeinated coffee intake were collected from probands before family investigation. RESULTS Dystonia was diagnosed in 27 relatives from 23 families (20% rate of family history for dystonia). No significant differences were found between familial and sporadic cases in the frequency of coffee drinking and eye diseases or in sex, age at onset, or tendency to spread. Multivariable conditional logistic analysis testing of 67 case patients and 127 family-matched unaffected siblings yielded a significant positive association between blepharospasm and prior eye diseases (adjusted odds ratio [OR] 2.5; 95% confidence interval [CI] 1.1-6.1; p = 0.03) and a significant inverse association between case status and ever coffee drinking (adjusted OR 0.23; 95% CI 0.1-0.8; p = 0.02). CONCLUSIONS The new information from this large family-based study on primary blepharospasm strongly supports eye diseases and coffee as risk factors for blepharospasm. The finding that the 2 environmental exposures exerted a similar influence on familial and sporadic blepharospasm, together with the convergent phenotypic expression in familial and sporadic cases, implies that familial and sporadic blepharospasm probably share a common etiologic background.

Abstract
BACKGROUND AND PURPOSE Despite the growing number of reports describing adult-onset primary lower limb dystonia (LLD) this entity has never been systematically evaluated in the general population of patients with primary adult-onset dystonia. METHODS From outpatients with adult-onset primary dystonia attending nine Italian University centres for movement disorders we consecutively recruited 579 patients to undergo a standardized clinical evaluation. RESULTS Of the 579 patients assessed, 11 (1.9%) (8 women, 3 men) had LLD, either alone (n = 4, 0.7%) or as part of a segmental/multifocal dystonia (n = 7, 1.2%). The age at onset of LLD (47.9 +/- 17 years) was significantly lower than the age at onset of cranial dystonias (57.9 +/- 10.7 years for blepharospasm, and 58.9 +/- 11.8 years for oromandibular dystonia) but similar to that of all the other adult-onset primary dystonias. The lower limb was either the site of dystonia onset (36.4%) or the site of dystonia spread (63.6%). In patients in whom LLD was a site of spread, dystonia seemed to spread following a somatotopic distribution. Only one patient reported a recent trauma involving the lower limb whereas 36.4% of the patients reported pain at the site of LLD. Only 64% of our patients needed treatment for LLD, and similarly to previously reported cases, the most frequently tried treatments was botulinum toxin and trihexyphenidyl. CONCLUSION The lower limb is an uncommon but possible topographical site of dystonia in adulthood that should be kept in consideration during clinical evaluation.

Abstract
Parkinson's disease (PD) is a chronic progressive disorder mainly affecting the motor system. PD is only partially controlled by symptomatic dopaminergic treatment. Therefore, motor rehabilitation can be used in PD to reduce complications and to train patients in the use of compensatory movement strategies. Rehabilitative practice is largely dependent on the efficiency of motor learning, i.e. the acquisition of new abilities or the adaptation of pre-existing ones. Although patients with PD are able to improve their motor performance through practice, the amount and persistence of clinical benefit are uncertain. Both ''implicit'' (procedural) and ''explicit'' (declarative) features of motor learning have been extensively investigated in patients with PD using neuropsychological testing, serial reaction time paradigms, and analysis of reaching movements. Evidence from these studies suggests an early impairment of ''explicit'' learning in PD, while ''implicit'' learning is relatively preserved. The consolidation of learned motor tasks is defective in PD and the mechanisms of motor learning seem to be independent from dopamine-replacement therapy. The knowledge of motor learning in PD is critical in designing more effective rehabilitative protocols.

Abstract
The endocrine and ovarian responses to prolonged adrenal stimulation at the time of corpus luteum (CL) regression were studied in non-lactating non-pregnant Friesian cows. Cows were synchronized with two cloprostenol (PG) injections 11 days apart (second PG referred as time 0). Experiment 1 was carried out on five animals in two phases with a resting period in between. Between -48 and 84 h, animals received 12 injections of either saline (CTR) or adrenocorticotrophic hormone (ACTH) agonist (Synacthen; SYN) every 12 h. Cortisol (C), progesterone (P4), oestradiol (E2) and LH were analysed in the blood samples collected every 8-12 h between days -3 and 4. Pulsatile LH release was studied 4 h before and 4 h after naloxone administration beginning at 96 h. Experiment 2 was carried out on four cows in a cross-over experimental design (two phases, with a resting period in between). Treatments were performed by administering either saline (CTR) or Synacthen (SYN) every 12 h between -36 and 24 h. The concentrations of C, P4 and E2 were measured in blood plasma every 4-12 h from days -3 to 3, then every day from days 5 to 9. In both experiments, ovaries were examined by ultrasonography every 1-3 days. ACTH administration induced a significant increase (p < 0.001) of plasma C lasting for 7 days (experiment 1), and for 3-4 days (experiment 2). Plasma C returned to baseline levels within 6 days (expt 1) or 36 h (expt 2) after treatment interruption. During the SYN phase, LH pre-ovulatory surge was not detectable. During the CTR phase, naloxone administration induced a significant increase (p < 0.05) of average LH concentrations that was not evident during the SYN phase. The dominant follicle development was retarded and mean plasma E2 concentrations were significantly lower during the SYN phase (p < 0.01). Luteolysis was completed within 2 days. However, P4 decline between 0 and 4 h was slower (p < 0.01) during the SYN phase. Our results indicate that, under prolonged adrenal stimulation, follicular development is delayed and LH release is impaired, which are independent of CL function.

Abstract
Creutzfeldt-Jakob disease (CJD) can occasionally present with a clinical picture resembling a corticobasal degeneration (CBD). Transcallosal inhibition, as tested by focal transcranial magnetic stimulation, is frequently absent or highly disrupted in CBD patients. We report a case of CJD presenting at the beginning of the disease as a CBD in which the ipsilateral silent period (iSP) was present and well detectable. This brief report shows that study of the iSP may be a useful diagnostic tool in order to differentiate CBD from syndromes presenting with similar clinical features.

Abstract
The aim of the study was to investigate the relationship between dyskinesias and motor fluctuations in patients with Parkinson's disease on l-dopa monotherapy. We identified 116 patients on l-dopa monotherapy treated between 1965 and 1992 and followed until death. Dyskinesias occurred in 102 patients. Of these, 48 only developed dyskinesias while 54 had both dyskinesias and motor fluctuations. Among patients with both complications, 49 developed dyskinesias before fluctuations, and only five had dyskinesias after the onset of fluctuations. Our findings suggest that dyskinesias predict the onset of motor fluctuations, and may share a common pathophysiological mechanism.

Abstract
The aim of this work was to investigate the secretion of dehydroepiandrosterone (DHEA), testosterone (T), dihydrotestosterone (DHT) and oestradiol (E) as biological markers in response to illegal administration of testosterone, 19-nortestosterone (N) and oestradiol, either alone or in combination. Twenty male Friesian calves (age 13-14 months) were allotted to a control group (n = 5), and five experimental groups (n = 3) each. Each experimental animal was repeatedly injected with one of the following hormonal treatments: E, T, N, T+E and N+E. Circulating DHEA, T, DHT and E were determined by radioimmunoassay. The administration of T alone did not induce any variation in plasma DHEA, T, DHT and E, which were similar to those in the control group. In contrast, DHEA, T and DHT were on average significantly lower in the T+E and N-treated groups (p < 0.01), whereas the administration of N+E resulted in the reduction of plasma T and DHT without any modification of plasma DHEA. The administration of E alone or in combination increased circulating levels of E but did not affect androgen plasma profiles. The results indicate that plasma levels of T do not permit detection of illegal treatments because plasma androgens always remained within the physiological range. Illegal E treatment could be detected in blood samples when they were collected at least every 20 days.

Abstract
The purpose of this work was to compare two different protocols of oestrous induction, using either a dopamine agonist (cabergoline) or a GnRH agonist (buserelin) in anoestrus bitches. The clinical trial involved 22 Beagle bitches, randomly allotted to two treatment groups: group A (n = 12) was orally administered cabergoline (Galastop(R); Centralvet-Vetem, Milan, Italy; 5 microg/kg SID), until the onset of cytological oestrus or for a maximum of 30 days and group B (n = 10) was treated with buserelin acetate, (Suprefact(R); Aventis Pharma, Milan, Italy), administered subcutaneously t.i.d., at 1.5 microg/kg for 11 days and 0.75 microg/kg for the following 3 days. Blood samples were collected twice a week to measure progesterone and prolactin concentration. Both cabergoline and buserelin produced a significant early decline in prolactin concentration (p < 0.01), but the effect of cabergoline lasted longer. Progesterone concentration was significantly affected by buserelin administration, showing a significant increase (p < 0.01) from day 3 to day 6 of treatment. Cabergoline confirmed its effectiveness in inducing oestrus as 10 of 12 bitches responded to the treatment, were mated and whelped. On the contrary, oestrus was observed in only three of 10 buserelin-treated bitches and in two of them 7 and 13 days after the end of treatment. These same two bitches accepted mating and conceived. The results suggest that in a clinical setting, dopaminergic treatment is the treatment of choice as it yields more consistent results and involves a much easier administration protocol.
