Development and Validation of the Questionnaire for Adaptive Hyperactivity and Goal Achievement (AHGA).

Objective: This paper illustrates the preliminary psychometric properties of the Questionnaire for Adaptive Hyperactivity and Goal Achievement (AHGA), aimed at measuring adaptive characteristics of hyperactivity and goal pursuit in older adults.

Methods: The 12-item scale was administered to a sample of 120 subjects (older adults) between February 2022 and June 2022. The reliability of AHGA was measured using Cronbach's alpha, and factor structure was established using parallel analysis (PA) and principal component analysis (PCA).

Training on adequate use of opioid analgesics in West and Central Africa: a neglected step on the way to access to essential medicines?

Alleviating acute and chronic pain is a moral imperative for health professionals and health systems, and it requires adequate access to and use of essential opioid analgesics. However, this is still a neglected issue in global health, with striking inequalities in opioids availability between high and low- and middle-income countries. Countries most affected by lack of access are those with a fragile political situation and weak regulatory and healthcare systems.

Normative Data for the NeuroCom Sensory Organization Test in Subjects Aged 80-89 Years.

Aging is known to increase the risk of falling. In older people, whose share in the total population is rising sharply, the Sensory Organization Test (SOT, Equitest NeuroCom) is a useful tool during rehabilitation and in clinical research for assessing postural stability, risk of falling, and balance improvement. Normative data for the SOT in the healthy population older than 79 years have not been previously published.

The influence of fish farm activity on the social structure of the common bottlenose dolphin in Sardinia (Italy).

In a wide variety of habitats, including some heavily urbanised areas, the adaptability of populations of common bottlenose dolphin () may depend on the social structure dynamics. Nonetheless, the way in which these adaptations take place is still poorly understood. In the present study we applied photo-identification techniques to investigate the social structure of the common bottlenose dolphin population inhabiting the Gulf of Alghero (Sardinia, Italy), analysing data recorded from 2008 to 2019.

Straying from the flatfish retinal plan: Cone photoreceptor patterning in the common sole (Solea solea) and the Senegalese sole (Solea senegalensis).

The retinas of nonmammalian vertebrates have cone photoreceptor mosaics that are often organized as highly patterned lattice-like distributions. In fishes, the two main lattice-like patterns are composed of double cones and single cones that are either assembled as interdigitized squares or as alternating rows. The functional significance of such orderly patterning is unknown.

Ontogenetic expression rhythms of visual opsins in senegalese sole are modulated by photoperiod and light spectrum.

In the fish retina, rods and cones are responsible for nocturnal vision and colour perception, respectively, and exhibit a repertoire of light-sensitive opsin photopigments that permits the adaptation to different photic environment. The metamorphosis of Senegalese sole determines a migration from pelagic to benthic environments, which is accompanied by essential changes in light intensity and spectrum. In this paper, we analysed the daily expression rhythms of rod opsin and five cone opsins during sole ontogeny in animals maintained under light-dark cycles of white (LDW), blue (LDB), red (LDR) and continuous white (LL) lights.

Quality of life perception in type 2 diabetes.

Purpose: Lifestyle analysis is often used for primary and secondary prevention in many chronic metabolic diseases, including diabetes. Questionnaires are simple and common methods for first investigation risk of factors related to the perception of quality of life (QoL). The present study evaluates the feasibility to use questionnaires for first investigation of risk factors, and ascertain whether the results of such questionnaires are associated with the perception of QoL.

Interferons-beta versus glatiramer acetate for relapsing-remitting multiple sclerosis.

Background: Interferons-beta (IFNs-beta) and glatiramer acetate (GA) were the first two disease-modifying therapies (DMTs) approved 20 years ago for the treatment of multiple sclerosis (MS). DMTs' prescription rates as first or switching therapies and their costs have both increased substantially over the past decade. As more DMTs become available, the choice of a specific DMT should reflect the risk/benefit profile, as well as the impact on quality of life.

NGR Tumor-Homing Peptides: Structural Requirements for Effective APN (CD13) Targeting.

Cyclic CNGRC (cCNGRC) peptides are very important targeting ligands for Aminopeptidase N (APN or CD13), which is overexpressed on the surface of many cancer cells. In this work we have (1) developed an efficient solid-phase synthesis and (2) tested on purified porcine APN and APN-expressing human cells two different classes of cCNGRC peptides: the first carrying a biotin affinity tag or a fluorescent tag attached to the carboxyl Arg-Cys-COOH terminus and the second with the tags attached to the amino H2N-Cys-Asn terminus. Carboxyl-terminus functionalized cCNGRC peptides 3, 6, and 8 showed good affinity for porcine APN and very good capacity to target and be internalized into APN-expressing cells.

Multitarget-directed tricyclic pyridazinones as G protein-coupled receptor ligands and cholinesterase inhibitors.

By following a multitarget ligand design approach, a library of 47 compounds was prepared, and they were tested as binders of selected G protein-coupled receptors (GPCRs) and inhibitors of acetyl and/or butyryl cholinesterase. The newly designed ligands feature pyridazinone-based tricyclic scaffolds connected through alkyl chains of variable length to proper amine moieties (e.g.

Comparative efficacy of interferon β versus glatiramer acetate for relapsing-remitting multiple sclerosis.

Interferon β (INFβ) and glatiramer acetate (GA) are widely used in patients with relapsing-remitting multiple sclerosis (RRMS). However, it is still unclear whether they have different efficacy. We performed a systematic search of head-to-head trials for gaining objective reliable data to compare the two drugs, using the Cochrane Collaboration methodology.

Interferons-beta versus glatiramer acetate for relapsing-remitting multiple sclerosis.

Background: Interferons (IFNs)-beta and glatiramer acetate (GA) were the first two disease-modifying therapies (DMTs) approved 15 years ago for the treatment of multiple sclerosis (MS). DMTs prescription rates as first or switching therapies and their costs have increased substantially over the past decade. As more DMTs become available, the choice of a specific DMT should reflect the risk/benefit profile, as well as the impact on quality profile.

Tricyclic pyrazoles. Part 6. Benzofuro[3,2-c]pyrazole: a versatile architecture for CB2 selective ligands.

A new series of 1H-benzofuro[3,2-c]pyrazole-3-carboxamides was synthesized. The novel compounds (15-24) were evaluated for their affinity to CB2 and CB1 cannabinoid receptors. The synthesis of the title compounds takes advantage of the acid-catalysed thermal cyclization of bicyclic hydrazone ethyl 2-(2-(2,4-dichlorophenyl)hydrazono)-2-(6-methyl-3-oxo-2,3-dihydrobenzofuran-2-yl)acetate to tricyclic ethyl 1-(2,4-dichlorophenyl)-6-methyl-1H-benzofuro[3,2-c]pyrazol-3-carboxylate.

Quality assessment of information about medications in primary care electronic patient record (EPR) systems.

Background: Many different brands of primary care electronic patient record (EPR) software are available to general practitioners (GPs). Their ability to support GPs in improving prescribing varies greatly.

Objective: To assess, using a ten-item tool, the quality of drug information provided by EPR software to support the appropriateness of prescriptions and to propose a list of quality standards for this type of application.

Risk Management Plans: are they a tool for improving drug safety?

Purpose: In 2005, new European legislation authorised Regulatory Agencies to require drug companies to submit a risk management plan (RMP) comprising detailed commitments for post-marketing pharmacovigilance. The aim of the study is to describe the characteristics of RMP for 15 drugs approved by the European Medicines Agency (EMA) and their impact on post-marketing safety issues.

Methods: Of the 90 new Chemical Entities approved through a centralised procedure by the EMA during 2006 and 2007, 15 of them were selected and their safety aspects and relative RMPs analysed.

Transient focal lesion in the splenium of the corpus callosum: MR imaging with an attempt to clinical-physiopathological explanation and review of the literature.

Purpose: This article discusses the possible pathophysiological conditions responsible for magnetic resonance imaging (MRI) finding of transient focal lesions in the splenium of the corpus callosum on the basis of our experience and a review of the literature.

Materials And Methods: In six patients undergoing computed tomography (CT) and MRI examinations, focal nonhemorrhagic lesions of the splenium of the corpus callosum were incidentally discovered. Patients had been referred for suspected encephalitis (n=2), dural sinus thrombosis (n=1) and multiple sclerosis (n=3).

Immunity to poliovirus among children and the elderly in north-east Italy.

Introduction: Italy and Europe were declared polio-free in June 2002, but increasing migration, even from undeveloped countries where polio still exists, may lead to a come-back of circulating poliovirus (PV) and infection in previously polio-free areas. It is consequently advisable to continue to monitor the immunity of the population in polio-free areas. The aim of this study was to assess the current prevalence of neutralizing antibodies in recently-immunized children and in elderly people who were never vaccinated.

On ring carbomers of cyclobutane, cyclopentane, and cyclodecane and cyclization reactions through bis(alkynyl-propargyl) coupling.

A copper-mediated procedure for terminal alkynyl-propargyl coupling has been applied to "skipped" bis-terminal undecatetrayne and 1,4-bis(pseudo)halobut-2-ynes with the aim of preparing ring carbomers of representative strained and loose cycloalkanes, namely [N]pericyclynes. Two unprecedented, cyclic. "skipped" polyynes with CH2 vertices have been isolated as mixtures of diastereoisomers: an isomer 1b and a dimer 2a of [5]pericyclyne 1a.

Binding of a desmetallo-porphyrin conjugate of Hoechst 33258 to DNA. III. Strong bonding to single-strand oligonucleotides.

The binding of the conjugate of Hoechst 33258 with 5,10,15,20-tetrakis (1-methyl-4-pyridyl)-21H,23H-porphyrin (PORHOE) to single-strand DNA has been detected by UV-vis spectrophotometry and 1H-NMR. The red-shift of porphyrin Soret band with strong hypochromicity indicates that the porphyrin moiety dominates in the interaction of the PORHOE with ssDNA. The affinity constants of PORHOE for d(GCATACAATTCG) or d(CGAATTGTATGC) were determined to be >10(5) M(-1), with strong cooperativity.

Binding of a porphyrin conjugate of Hoechst 33258 to DNA. II. NMR spectroscopic studies detect multiple binding modes to a 12-mer nonself-complementary duplex DNA.

We have probed by 1H NMR spectroscopy the molecular basis of the interaction between Hoechst 33258 conjugated to a des-metalloporphyrin and a non self-complementary duplex DNA sequence, designed on the known chemical nuclease selectivity of this system. The imino NMR spectra are consistent with two distinct families of structure, that is, PORHOE binding either way along the duplex. 2D spectral, T2, and linewidth data suggest multiple species within the two conformational families.

Binding of a porphyrin conjugate of Hoechst 33258 to DNA. I. UV-visible and melting studies detect multiple binding modes to a 12-mer nonself-complementary duplex.

Relative to ligand-free duplex DNA, the melting temperature of the 1:1 complex of the duplex d(CGAATTGTATGC):d(GCATACAATTCG) with the conjugate of Hoechst 33258 with a des-metalloporphyrin, increased from 42 to 60.5 degrees C indicating strong ligand binding. UV-vis spectrophotometric titration detected more than one class of binding site (apparent dissociation constants approximately 0.

Nuclease activity and binding characteristics of a cationic "manganese porphyrin-bis(benzimidazole) dye (Hoechst 33258)" conjugate.

To increase the binding affinity and/or the sequence selectivity of the chemical nuclease manganese-(III) tetrakis(4-N-methylpyridiniumyl)porphyrin, we synthesized a conjugate molecule by associating a tris(4-N-methylpyridiniumyl)metalloporphyrin motif to Hoechst 33258 (H33258), a DNA minor groove binding dye known for its selective affinity for A-T tracts. Selected double-stranded (ds) 35-mer oligodeoxyribonucleotides have been used to probe DNA chain breakages induced by the managanese derivative of the conjugate after activation by potassium monopersulfate. Gel electrophoresis analyses show that DNA cuts were generated by the metalloporphyrin moiety of the hybrid molecule, with the H33258 entity interacting in two different possible orientations, upstream or downstream, with its preferred affinity site inside the minor groove.
