Some remarks and experiences on higher education and sustainable development

7Education for sustainable development should be based on proper environmental management. The general objective of this study is to highlight key aspects of environmental education, with specific objectives. Inclusive education addresses the learning needs with a focus on those who are vulnerable to marginalization and exclusion. Ethics plays a vital role in environmental management and should be a cornerstone to raise awareness of new forms of relationship with the particular and global environment. The cosmovision of indigenous peoples should be respected, including the indissoluble union of each culture with the environment. The feminization of labor is relevant in horticulture crops, with an active role of women in the organization of work. The connections between education and the world of work are key, with preparation for new and indeterminate forms of employment, paying attention to social skills in the context of increasing globalization. University Social Responsibility (USR) implies that the University must act ethically in knowledge transfer, promoting sustainable development. Sustainable development involves new systems of thought, it requires creativity and critical thinking, and an alternative is the creation of role-playing, to lead people to thinking in different ways. It is essential that the new professionals act without static patterns, integrating interdisciplinary teams, to search for the answer to a problem, offering original and innovative alternatives

Neuro-hormonal effects of physical activity in the elderly.

Thanks to diagnostic and therapeutic advances, the elderly population is continuously increasing in the western countries. Accordingly, the prevalence of most chronic age-related diseases will increase considerably in the next decades, thus it will be necessary to implement effective preventive measures to face this epidemiological challenge. Among those, physical activity exerts a crucial role, since it has been proven to reduce the risk of cardiovascular diseases, diabetes, obesity, cognitive impairment and cancer. The favorable effects of exercise on cardiovascular homeostasis can be at least in part ascribed to the modulation of the neuro-hormonal systems implicated in cardiovascular pathophysiology. In the elderly, exercise has been shown to affect catecholamine secretion and biosynthesis, to positively modulate the renin-angiotensin-aldosterone system and to reduce the levels of plasma brain natriuretic peptides. Moreover, drugs modulating the neuro-hormonal systems may favorably affect physical capacity in the elderly. Thus, efforts should be made to actually make physical activity become part of the therapeutic tools in the elderly. © 2013 Femminella, de Lucia, Iacotucci, Formisano, Petraglia, Allocca, Ratto, DAmico, Rengo, Pagano, Bonaduce, Rengo and Ferrara

Mandibular osteosarcoma in a goat

Introduction-A few large surveys on tumour prevalence in goats indicate that tumours in general are quite common in this species. Reviews of neoplastic diseases in goats indicate a prevalence ranging from 0,8 to 11%. However, osteogenic tumours arising from facial bones in goats are rare. Regarding oral localization only a few mesenchymal tumours have been described arising from the gengiva. Case presentation-A 4-year old, female crossbred goat was referred with a history of dysorexia and a slow growing painful mass on the face. On physical examination the animal showed poor body condition and the left side of the face was deformed by a voluminous mass which, at the inspection of the oral cavity, displaced the maxillary teeth. Differential diagnoses included os-teomyelitis and benign (osteoma, chondroma, ossifying and non ossifying fibroma, odontogenic tumours) as well as malignant (osteosarcoma, chondrosarcoma) mesenchymal tumours arising from either the connective tissue and bone. The goat was euthanized because of the extension of the lesion and a complete necropsy was performed. Grossly, the face was deformed by the presence of a hard mass arising from the branch of the left mandible. Histologically the oral mass was composed of heterogeneous proliferation of malignant osteoblasts intermigled with brightly eosinophilic strands or island of osteoid matrix. Neoplastic cells, interpreted as malignant osteoblasts, were characterized by plump to round or spindle-shape morphology, with moderate basophilic cytoplasm and an eccentrically located voluminous nucleus containing a large prominent nucleolus. Mitotic figures were found and were either bipolar and atypical. At necropsy no metastases were found and the final diagnosis was non-metastasizing mandibular osteoblastic osteosarcoma. Conclusion-In conclusion, regardless the type of tumour, the goat was euthanized because of the extension and the severity of the lesion. Necropsy and histological examination were necessary to correctly classify the tumour as a non-metastasizing mandibular osteosarcoma

Extracellular matrix inhibits structural and functional plasticity of dendritic spines in the adult visual cortex

Brain cells are immersed in a complex structure forming the extracellular matrix. The composition of the matrix gradually matures during postnatal development, as the brain circuitry reaches its adult form. The fully developed extracellular environment stabilizes neuronal connectivity and decreases cortical plasticity as highlighted by the demonstration that treatments degrading the matrix are able to restore synaptic plasticity in the adult brain. The mechanisms through which the matrix inhibits cortical plasticity are not fully clarified. Here we show that a prominent component of the matrix, chondroitin sulfate proteoglycans (CSPGs), restrains morphological changes of dendritic spines in the visual cortex of adult mice. By means of in vivo and in vitro two-photon imaging and electrophysiology, we find that after enzymatic digestion of CSPGs, cortical spines become more motile and express a larger degree of structural and functional plasticity

Acute stress impairs sensorimotor gating via the neurosteroid allopregnanolone in the prefrontal cortex

Ample evidence indicates that environmental stress impairs information processing, yet the underlying mechanisms remain partially elusive. We showed that, in several rodent models of psychopathology, the neurosteroid allopregnanolone (AP) reduces the prepulse inhibition (PPI) of the startle, a well-validated index of sensorimotor gating. Since this GABAA receptor activator is synthesized in response to acute stress, we hypothesized its participation in stress-induced PPI deficits. Systemic AP administration reduced PPI in C57BL/6J mice and Long-Evans, but not Sprague-Dawley rats. These effects were reversed by isoallopregnanolone (isoAP), an endogenous AP antagonist, and the GABAA receptor antagonist bicuculline and mimicked by AP infusions in the medial prefrontal cortex (mPFC). Building on these findings, we tested AP's implication in the PPI deficits produced by several complementary regimens of acute and short-term stress (footshock, restraint, predator exposure, and sleep deprivation). PPI was reduced by acute footshock, sleep deprivation as well as the combination of restraint and predator exposure in a time- and intensity-dependent fashion. Acute stress increased AP concentrations in the mPFC, and its detrimental effects on PPI were countered by systemic and intra-mPFC administration of isoAP. These results collectively indicate that acute stress impairs PPI by increasing AP content in the mPFC. The confirmation of these mechanisms across distinct animal models and several acute stressors strongly supports the translational value of these findings and warrants future research on the role of AP in information processing

La percepción de la calidad del suelo por parte de los productores en una prueba piloto en el área pampeana

p.97-106Para conocer la percepción de la calidad de suelos por parte de productores agropecuarios del área pampeana se aplicó un cuestionario desarrollado en la Universidad de Nebraska (USA). El cuestionario utiliza propiedades consideradas indicadores de calidad y la calificación es de tipo cuali - cuantitativo, respondiendo a pautas establecidas. La muestra fue de tipo casual y se aplicó a productores de pampa ondulada (PO) pampa arenosa (PA) y pampa arenosa semiárida (PAs). Los resultados indican que para ser utilizado en estas zonas se deben introducir algunos ajustes. Las propiedades hídricas, retención de agua, drenaje e infiltración resultan de difícil interpretación y dan origen a respuestas contrapuestas. Los indicadores textura, actividad biológica, dureza y sensación al tacto requieren de una discusión previa con el encuestado y resultaron de difícil evaluación. La calificación final correspondió a 79 por ciento de la calidad en PO, 62 por ciento en PA y 56 por ciento en PAs. La identificación de rasgos positivos y negativos en las percepciones de los productores respecto de la calidad del suelo laboreado permitió recopilar información para el diseño de políticas de gestión. Se considera que la aplicación del cuestionario tiene un doble valor, el de enseñanza, por la inquietud que despertó en los productores y el de reconocimiento del recursos suelo. Se introduce modificaciones a ser aplicadas en futurras evaluaciones como la variabilidad espacial que responde a la morfología del paisaje y que es incluida an la valoración de los encuestados

Efficacy of capacitive resistive monopolar radiofrequency in the physiotherapeutic treatment of chronic pelvic pain syndrome : study protocol for a randomized controlled trial

Chronic pelvic pain syndrome (CPPS) is a multifactorial disorder that affects 5.7% to 26.6% of women and 2.2% to 9.7% of men, characterized by hypersensitivity of the central and peripheral nervous system affecting bladder and genital function. People with CPPS have much higher rates of psychological disorders (anxiety, depression, and catastrophizing) that increase the severity of chronic pain and worsen quality of life. Myofascial therapy, manual therapy, and treatment of trigger points are proven therapeutic options for this syndrome. This study aims to evaluate the efficacy of capacitive resistive monopolar radiofrequency (CRMRF) at 448kHz as an adjunct treatment to other physiotherapeutic techniques for reducing pain and improving the quality of life of patients with CPPS. This triple-blind (1:1) randomized controlled trial will include 80 women and men with CPPS. Participants will be randomized into a CRMRF activated group or a CRMRF deactivated group and receive physiotherapeutic techniques and pain education. The groups will undergo treatment for 10 consecutive weeks. At the beginning of the trial there will be an evaluation of pain intensity (using VAS), quality of life (using the SF-12), kinesiophobia (using the TSK-11), and catastrophism (using the PCS), as well as at the sixth and tenth sessions. The results of this study will show that CRMRF benefits the treatment of patients with CPPS, together with physiotherapeutic techniques and pain education. These results could offer an alternative conservative treatment option for these patients. ClinicalTrials.gov . Registered on 8 January 2019.

Survival analysis in single N2 station lung adenocarcinoma: The prognostic role of involved lymph nodes and adjuvant therapy

Background: Prognostic factors in patients with single mediastinal station (sN2) involvement continues to be a debated issue. Methods: Data on 213 adenocarcinoma patients with sN2 involvement and who had undergone complete anatomical lung resection and lymphadenectomy, were retrospectively reviewed. Clinical and pathological characteristics together with adjuvant therapy (AD) and node (N) status classifications (number of resected nodes (#RN), number of metastatic nodes (#MN), and node ratio (#MN/#RN = NR) were analyzed. Results: Univariable analysis confirmed that age (0.009), #MN (0.009), NR (0.003), #N1 involved stations (p = 0.003), and skip metastases (p = 0.005) were related to overall survival (OS). Multivariable analysis confirmed, as independent prognostic factors, age <66 years and NR with a three-year OS (3YOS) of 78.7% in NR < 10% vs. 46.6% in NR > 10%. In skip metastases, NR (HR 2.734, 95% CI 1.417–5.277, p = 0.003) and pT stage (HR2.136, 95% CI 1.001–4.557, p = 0.050) were confirmed as independent prognostic factors. AD did not influence the OS of patients with singular positive lymph nodes (p = 0.41), while in patients with multiple lymph nodes and AD, a significantly better 3YOS was demonstrated, i.e., 49.1% vs. 30% (p = 0.004). In patients with N2 + N1 involvement, age (p = 0.002) and AD (p = 0.022) were favorable prognostic factors. Conclusions: Adenocarcinoma patients with single N2 station involvement had a favorable outcome in the case of skip metastases and low NR. Adjuvant therapy improves survival with multiple nodal involvement, while its role in single node involvement should be clarified

Cancer incidence in pet dogs: findings of the Animal Tumor Registry of Genoa, Italy.

Background: The occurrence of spontaneous tumors in pet animals has been estimated in a few European and North American veterinary cancer registries with dissimilar methodologies and variable reference populations. Objectives: The Animal Tumor Registry (ATR) of Genoa, Italy, was established in 1985 with the aim of estimating the occurrence of spontaneous tumors in dogs. Methods: Six thousand seven hundred and forty-three tumor biopsy specimens were received from local veterinarians in the Municipality of Genoa between 1985 and 2002. Three thousand and three hundred and three (48.9%) biopsy specimen samples were diagnosed as cancer and were coded according to the International Statistical Classification of Diseases (ICD-9). Results: Mammary cancer was the most frequently diagnosed cancer in female dogs, accounting for 70% of all cancer cases. Incidence of all cancers was 99.3 per 100,000 dog-years (95% CI: 93.6–105.1) in male dogs and 272.1 (95% CI: 260.7–283.6) in female dogs. The highest incidence rates were detected for mammary cancer (IR = 191.8, 95% CI: 182.2–201.4) and for non-Hodgkin's lymphoma (IR = 22.9, 95% CI: 19.7–26.5) in bitches and for non-Hodgkin's lymphoma (IR = 19.9, 95% CI: 17.4–22.7) and skin cancer (IR = 19.1, 95% CI: 16.6–21.8) in male dogs. All cancer IR increased with age ranging between 23.7 (95% CI: 18.4–30.1) and 763.2 (95% CI: 700.4–830.1) in bitches and between 16.5 (95% CI: 12.8–21.1) and 237.6 (95% CI: 209.1–269.0) in male dogs aged ≤3 years and >9–11 years. Conclusion: This study summarizes the work done by the ATR of Genoa, Italy, between 1985 and 2002. All cancer incidence was 3 times higher in female than in male dogs, a difference explained by the high rate of mammary cancer observed in bitches. Because a biopsy specimen was required to make a cancer diagnosis, cancer rates for internal organs cancers, such as respiratory and digestive tract cancers may have been underestimated in the study population
