The collection of Brendel Botanical Models at the Botanical Garden of Naples, Italy
The Botanical Garden of Naples has a collection of papier-mâché models that reproduce plant structures, whole plants, or fungi. They are known as Brendel Models, named after the German Company that built and supplied them to the Botanical Garden in the early nineteenth century. For their state of decay, due to time and continuous use for educational purposes, the models have undergone recovery interventions. Given their historical and artistic interest, and in order to preserve them, the models are no longer used today. In order not to completely lose such a cultural heritage for didactics, a CD-ROM has been created which includes, for each species reproduced by the models, photos in nature of the plants represented and didactic cards re-porting all the useful information for the use of models in computer mode

Vitamin A Metabolism: An Update
Retinoids are required for maintaining many essential physiological processes in the body, including normal growth and development, normal vision, a healthy immune system, normal reproduction, and healthy skin and barrier functions. In excess of 500 genes are thought to be regulated by retinoic acid. 11-cis-retinal serves as the visual chromophore in vision. The body must acquire retinoid from the diet in order to maintain these essential physiological processes. Retinoid metabolism is complex and involves many different retinoid forms, including retinyl esters, retinol, retinal, retinoic acid and oxidized and conjugated metabolites of both retinol and retinoic acid. In addition, retinoid metabolism involves many carrier proteins and enzymes that are specific to retinoid metabolism, as well as other proteins which may be involved in mediating also triglyceride and/or cholesterol metabolism. This review will focus on recent advances for understanding retinoid metabolism that have taken place in the last ten to fifteen years
Association of kidney disease measures with risk of renal function worsening in patients with type 1 diabetes
Background: Albuminuria has been classically considered a marker of kidney damage progression in diabetic patients and it is routinely assessed to monitor kidney function. However, the role of a mild GFR reduction on the development of stage 653 CKD has been less explored in type 1 diabetes mellitus (T1DM) patients. Aim of the present study was to evaluate the prognostic role of kidney disease measures, namely albuminuria and reduced GFR, on the development of stage 653 CKD in a large cohort of patients affected by T1DM. Methods: A total of 4284 patients affected by T1DM followed-up at 76 diabetes centers participating to the Italian Association of Clinical Diabetologists (Associazione Medici Diabetologi, AMD) initiative constitutes the study population. Urinary albumin excretion (ACR) and estimated GFR (eGFR) were retrieved and analyzed. The incidence of stage 653 CKD (eGFR < 60 mL/min/1.73 m2) or eGFR reduction > 30% from baseline was evaluated. Results: The mean estimated GFR was 98 \ub1 17 mL/min/1.73m2 and the proportion of patients with albuminuria was 15.3% (n = 654) at baseline. About 8% (n = 337) of patients developed one of the two renal endpoints during the 4-year follow-up period. Age, albuminuria (micro or macro) and baseline eGFR < 90 ml/min/m2 were independent risk factors for stage 653 CKD and renal function worsening. When compared to patients with eGFR > 90 ml/min/1.73m2 and normoalbuminuria, those with albuminuria at baseline had a 1.69 greater risk of reaching stage 3 CKD, while patients with mild eGFR reduction (i.e. eGFR between 90 and 60 mL/min/1.73 m2) show a 3.81 greater risk that rose to 8.24 for those patients with albuminuria and mild eGFR reduction at baseline. Conclusions: Albuminuria and eGFR reduction represent independent risk factors for incident stage 653 CKD in T1DM patients. The simultaneous occurrence of reduced eGFR and albuminuria have a synergistic effect on renal function worsening
Use of medicinal plants in the South-Eastern area of the Partenio Regional Park (Campania, Southern Italy)
Ethnopharmacological relevance: This study documents the pharmaceutical importance of plant resources in the South-Eastern area of the Partenio Regional Park (PRP), inland Campania, Avellino province. This is reflected in the great diversity of plants used for medicinal purposes as well as in their wide range of medicinal applications.
Materials and methods: In order to collect information on medicinal plants used in the investigated area and to maximize the collection of local knowledge, informants were randomly contacted in the streets, squares and fields. Data were collected through both open and semi-structured interviews with native people between April 2012 and April 2013.
Results: The study recorded 87 plant species belonging to 76 genera and 35 families used as medicine for treating various diseases, both human and veterinary. Herbs represent the majority (56 species), followed by trees (18) and shrubs (13). Among the recorded plants, leaves were the most frequently used and topic use is the most common remedy. Cough is the most treated human disease followed by wounds healing.
Conclusion: The investigated area is endowed with a strong tradition of herbal medicine usage for primary healthcare (PHC). The preservation of this knowledge is due to the continued use of plants for PHC by the local community. This is due to the fact that in the study area still exists an oral tradition that allows the persistence of such information. Recovering ancient knowledge is very important for preserving ethno-biodiversity and to discover new entities for a further evaluation of their biological activity

Effects of ACTH and corticosteroids on phenylethanolamine-N-methyltransferase (PNMT) expression as determined by immunocytochemical localization in the adrenal gland of the lizard Podarcis sicula
This study was undertaken to investigate whether, in the lizard Podarcis sicula, the expression of adrenaline synthesizing enzyme phenylethanolamine-N-methyltransferase (PNMT) is influenced by variations in corticosteroid levels. Adrenal glands of specimens treated with ACTH or corticosteroids were collected and stained with avidin-biotin complex (ABC) and immunogold techniques, for light and electron microscopical observations, respectively. In non treated specimens, positive staining was mainly confined to the catecholamine containing cells (adrenaline cells), located closer to the steroidogenic ones. In treated specimens, instead, positive staining was found in all the cells of the chromaffin portion of the gland (adrenaline and noradrenaline cells). Immunoelectron microscopy confirmed the distribution of immunoreactive cells observed at the light microscope. These results support the hypothesis that corticosteroids regulate PNMT expression in reptilian adrenal glands similarly to what occurs in mammals
Le piante medicinali nella storia: nuovi criteri espositivi nell'Orto Botanico di Napoli.
Attualmente, nello svolgimento delle attività didattiche l’Orto Botanico di Napoli manifesta l’intento di adottare nuovi criteri espositivi per richiamare un numero sempre crescente di visitatori. In tale ottica, nell’area denominata Sezione Sperimentale delle Piante Officinali, che ospita in coltivazione specie usate dall’uomo per scopi diversi, è stato recentemente realizzato un nuovo settore secondo criteri diversi da quelli tradizionali. Tale zona, dedicata alle piante medicinali, è stata progettata e realizzata secondo un criterio storico-temporale considerando le farmacopee delle tradizioni mediche più consolidate
