[PMID: 38689957 PMCID: PMC11059503 DOI: 10.1016/j.heliyon.2024.e28712] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/20/2023] [Revised: 03/21/2024] [Accepted: 03/22/2024] [Indexed: 05/02/2024] Open
Abstract
Aims The aims of this study were to verify if a 5-week cognitive-motor training (CMT) using FitlightsTM induced changes in young adult judo athletes compared to a non-intervention group. Specifically, it was verified if CMT influenced executive functions (EFs), physical fitness and brain-derived neurotrophic factor (BDNF) levels. Additionally, athletes' competitive results were compared between groups. Method Twenty-seven athletes (14 males and 13 females; age = 19.5 ± 2.0 years) were assigned to the Fitlight (FG) and control (CG) groups which performed 5 weeks of CMT, respectively, including 25 min per day of Fitlight training or traditional judo practice. All participants performed cognitive (flanker task and forward/backward digit span) and fitness tests (counter movement jump, handgrip test, dynamic and isometric chin up). In addition, BDNF was collected by saliva sampling and competitive results after the intervention period were considered. Results RM-ANOVA showed significant differences in FG for the accuracy of flanker (p = 0.028) and backward digit span (p < 0.001). Moreover, significant differences in FG were found for relative dynamic chin up (p = 0.027) and counter movement jump (p = 0.05). In addition, a significant difference in FG was found for competitive results after the intervention period (p < 0.01).No significant differences were found for BDNF and other cognitive and fitness measures (p > 0.05). Conclusion A 5-week judo-specific CMT improved EFs and motor performance in élite judo athletes. It seems that CMT with Fitlight™ could be considered an additional support to coaches during the training period.

Somatosensory-guided tool use modifies arm representation for action. Sci Rep 2019; 9:5517. [PMID: 30940857 PMCID: PMC6445103 DOI: 10.1038/s41598-019-41928-1] [Citation(s) in RCA: 24] [Impact Index Per Article: 4.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/08/2018] [Accepted: 03/20/2019] [Indexed: 01/28/2023] Open
Abstract
Tool-use changes both peripersonal space and body representations, with several effects being nowadays termed tool embodiment. Since somatosensation was typically accompanied by vision in most previous tool use studies, whether somatosensation alone is sufficient for tool embodiment remains unknown. Here we address this question via a task assessing arm length representation at an implicit level. Namely, we compared movement’s kinematics in blindfolded healthy participants when grasping an object before and after tool-use. Results showed longer latencies and smaller peaks in the arm transport component after tool-use, consistent with an increased length of arm representation. No changes were found in the hand grip component and correlations revealed similar kinematic signatures in naturally long-armed participants. Kinematics changes did not interact with target object position, further corroborating the finding that somatosensory-guided tool use may increase the represented size of the participants’ arm. Control experiments ruled out alternative interpretations based upon altered hand position sense. In addition, our findings indicate that tool-use effects are specific for the implicit level of arm representation, as no effect was observed on the explicit estimate of the forearm length. These findings demonstrate for the first time that somatosensation is sufficient for incorporating a tool that has never been seen, nor used before.

Abstract
BACKGROUND The incidence of asymptomatic, sporadic, small non-functioning pancreatic neuroendocrine neoplasms (NF-PNENs) has increased in recent decades. Conservative treatment has been advocated for these tumours. The aim of this study was systematically to evaluate the literature on active surveillance and to compare this with surgical management for asymptomatic sporadic small NF-PNENs. METHODS PubMed, Embase and the Cochrane Library were searched systematically for studies that compared the active surveillance of asymptomatic, sporadic, small NF-PNENs with surgical management. PRISMA guidelines for systematic reviews were followed. RESULTS After screening 3915 records, five retrospective studies with a total of 540 patients were included. Of these, 327 patients (60·6 per cent) underwent active surveillance and 213 (39·4 per cent) had surgery. There was wide variation in the tumour diameter threshold considered as inclusion criterion (2 cm to any size). The median length of follow-up ranged from 28 to 45 months. Measurable tumour growth was observed in 0-51·0 per cent of patients. Overall, 46 patients (14·1 per cent) underwent pancreatic resection after initial conservative treatment. In most patients the reason was an increase in tumour size (19 of 46). There were no disease-related deaths in the active surveillance group in any of the studies. CONCLUSION This systematic review suggests that active surveillance of patients affected by sporadic, small, asymptomatic NF-PNENs may be a good alternative to surgical treatment.

Addition of different concentrations of prostasome-like vesicles at neutral or slightly alkaline pH decreases canine sperm motility. Andrology 2016; 5:160-168. [PMID: 27676322 DOI: 10.1111/andr.12286] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/15/2016] [Revised: 08/18/2016] [Accepted: 08/22/2016] [Indexed: 11/27/2022]
Abstract
Prostasome-like vesicles (PV) are components of the canine prostatic fluid during ejaculation and despite some enzymatic activities have been identified recently, their functions in the reproductive events in this species are still poorly understood. In this study, we evaluated at neutral or slightly alkaline pH, the effects of different concentrations of purified PV on sperm cell motility characteristics and the impact on the short- and long-term preservation of preserved semen maintained at room temperature. Two different experiments were performed. In the first experiment, purified PV were added at increasing concentration (1.25, 2.5, 5, 10, and 20 μL equivalent to 1, 2, 4, 8, and 16 μg of protein, respectively) to aliquots of 100 μL of preserved semen maintained at 22 °C at the following time points: 0, 30, 60, 120, 240, and 480 min. Computer-assisted sperm motility characteristics and pH were assessed three times at each time points, for each sample and for every concentrations. In the second experiment, the purified PV were added with the same methods as described above but only at time 0. Sperm motility characteristics and pH were assessed over the time. This study showed how the addition of purified PV to preserved semen affects negatively (p < 0.05) at neutral and alkaline pH, both total and progressive motility in a concentration depending manner. Furthermore, prostasome addition was demonstrated to change the quality of sperm movement which may represent a mechanism facilitating sperm cells attachment to the uterine epithelium and facilitating energy preservation before fertilization.

Abstract
The present study examines the relationship between reproductive and seminal characteristic with blood flow supply of the testis in male dogs by means of Doppler ultrasonography. Five male dogs were subject to a clinical examination, blood sampling, B-Mode and Doppler ultrasonography of the testis, semen evaluation at collections and after storage at 4°C for 24, 48 and 72 h in three replicates 30 days apart. Peak Systolic Velocity was positively correlated with testicular volume and negatively with live sperm at collections and after 24h. A negative correlation existed between Resistive Index and Pulsatility Index with total and progressive motility at collections and also after 24, 48 and 72 h. Resistive Index and Pulsatility Index were also negatively correlated with the percentage of membrane intact sperms with curled tails at collections while the latter was positively correlated with End Diastolic Velocity. Moreover, positive linear correlations of weight with bilateral testicular volume and total sperm concentration and also between age and abnormal sperm at collections and after 24h were established. The results suggest that the Resistive Index and Pulsatility Index seem to be potential markers of seminal quality in dogs.

Abstract
Apolipoprotein-E (Apo-E) genotype and allele frequencies were evaluated in patients with late-onset probable Alzheimer's disease (LOAD; n = 64), early-onset probable Alzheimer's disease (EOAD; n = 32), possible Alzheimer's disease (pAD; n = 44), vascular dementia (VD; n = 12), age-associated memory impairment (AAMI; n = 15) and 40 healthy age-matched controls. APO-E was performed by polymerase chain reaction products digested by the restriction enzyme HhaI. A statistically significant increase of epsilon4 frequency was found in LOAD as compared to the other groups, and in pAD with respect to controls, while VD and AAMI groups did not disclose any difference as regards to control subjects. Multivariate analysis showed a significant association of epsilon4 with female gender. Our results confirm the increased frequency of epsilon4 in both probable and possible LOAD, failing to show a similar trend in VD and AAMI.

Abstract
In order to evaluate the prevalence of non-suppression after dexamethasone in psychogeriatrics and to further verify the reliability of the neurobiological information obtained, dexamethasone suppression test was carried out in a geriatric population composed of patients with dementia of Alzheimer type, vascular dementia, stroke and age and sex-matched controls. Basal cortisol levels did not differ among groups and was positively correlated to age. Prevalence of non-suppression, defined according to Carroll's criterion was high in the pathological groups studied, and relatively high in controls, showing no diagnostic value. Unlikely suppressors, the time course of mean plasma corticol levels of non-suppressors was highly heterogeneous in each group considered, especially in the pathological groups. More restrictive criteria for the definition of non-suppressors are proposed, in order to increase the specificity of the test when applied to psychogeriatrics.

Abstract
Arrhythmogenic right ventricular dysplasia is a pathologic condition of unknown origin that primarily affects the right ventricle free wall characterized by progressive atrophy with fibrous-fatty substitution of the myocardium. The patient affected may present in childhood or as an adult with cardiomegaly or/and ventricular arrhythmias with a left bundle branch block configuration. The reports of familial occurrence suggest the etiologic role of a genetic defect with autosomal dominance and variable expression and penetrance, an alternative, myocarditis (toxic or infectious) is a possible cause. The aim of the present study is an non-invasive instrumental evaluation of the family of a young patient affected by arrhythmogenic right ventricle dysplasia. The authors evaluated 10 patients, 7 women and 3 men, all asymptomatic, with electrocardiography, exercise stress test on a bicycle ergometer, 24-hour Holter monitoring and two-dimensional echocardiography. A patient had certain ARVD diagnosis, while in the other 9 patients all the instrumental investigations were normal. This observation seem to confirm that ARVD may be familial and justify a systematic in-depth familial study in all demonstrated cases of ARVD and the follow-up of all patients identified who had arrhythmias or isolated right ventricular morphologic anomalies.

Abstract
Levels of neuron-specific enolase (NSE), a glycolytic enzyme localized in neurons, were measured in serum and cerebrospinal fluid (CSF) of patients with early-onset (e-AD) and late-onset (l-AD) Alzheimer's disease, vascular dementia (VD) and controls. Mean CSF NSE levels in patients with Alzheimer's disease did not significantly differ from those in controls, although in the AD group a correlation was found between NSE levels and severity of cognitive deficits. In VD patients, CSF NSE was lower than in controls or in AD patients. These findings are of physiopathological interest but suggest that CSF NSE is not a useful biological marker in dementia disorders.

Abstract
A 46 years old man with WPW syndrome, due to a posteroseptal accessory pathway, was admitted because of orthodromic reciprocating tachycardia, 210/m'in frequency. At the end of the carotid sinus massage, for accomplish the conversion of tachycardia to sinus rhythm, the orthodromic reciprocating supraventricular tachycardia degenerated into atrial fibrillation associated with high ventricular rate and the presence of hemodynamic instability, reverted to sinus rhythm by intravenous propafenone. Vagal stimulation, induced by carotid sinus massage, probably caused dispersion of atrial refractorines and intraatrial reentry, converting the orthodromic tachycardia into atrial fibrillation. The transesophageal electrophysiologic study, executed in treatment with propafenone, not documented the accessory connection and atrial fibrillation or reciprocating tachycardia were not inducible.

Abstract
We have previously shown that interleukin-2 (IL-2) is able to induce the generation of natural killer (NK) activity in bone marrow (BM) cells from mice pretreated with 5-fluorouracil. IL-2 alone could dose-dependently induce NK activity in marrow cells and interleukin-4 (IL-4) has dual effect on the NK activity in that, depending on the concentration of IL-2, IL-4 inhibits or stimulates development of NK cells. The inhibitory effect was in part antagonized by interleukin-1 alpha. These effects were not obtained when NK-reactive spleen cells were cultured with the same concentrations of IL-2 or IL-2 plus IL-4 with or without irradiated BM cells as feeders. The effects of IL-4 were also obtained by preincubation for 6-24 hr before culturing with IL-2 alone and correlated with the expression of interleukin-2 receptor (IL-2/r), suggesting that IL-4 might play a regulatory role in the IL-2-dependent generation of NK cells in BM.

Abstract
The Authors, after a careful examination of the literature on endometrial hyperplasias, review the results of a preliminary study on 15 patients affected with postmenopausal metrorrhagia, cured by Danazol (200 mg/die) through 90 consecutive days. Also recognizing the best tolerance to the drug and the low incidence of the side effects, they think the results obtained by Danazol need further confirmation by more protracted controls.
