The neuronal ceroid-lipofuscinoses: A historical introduction
2013
AbstractThe neuronal ceroid-lipofuscinoses (Batten disease) collectively constitute one of the most common groups of inherited childhood onset neurodegenerative disorders, and have also been identified in many domestic and laboratory animals. The group of human neuronal ceroid-lipofuscinoses currently comprises 14 genetically distinct disorders, mostly characterised by progressive mental, motor and visual deterioration with onset in childhood or adolescence. Abnormal autofluorescent, electron-dense granules accumulate in the cytoplasm of nerve cells, and this storage process is associated with selective destruction and loss of neurons in the brain and retina. The present paper outlines near…
Innovative strategies to treat skin wounds with mangiferin: fabrication of transferosomes modified with glycols and mucin
2020
Aim: The moisturizing properties of glycerol, the penetration enhancing capability of propylene glycol and the bioadhesive properties of mucin were combined to improve the carrier capabilities of transfersomes and the efficacy of mangiferin in the treatment of skin lesions. Materials & methods: Mangiferin was incorporated in transfersomes and glycoltransfersomes, which were also modified with mucin. The physico–chemical features were assessed, along with the efficacy against oxidative stress and skin wounds in vitro and in vivo. Results: Glycoltransfersomes promoted the deposition of mangiferin in epidermis and dermis, protected fibroblasts from oxidative stress and stimulated their pr…
Enzymatic biodiesel: Challenges and opportunities
2014
The chemical-catalyzed transesterification of vegetable oils to biodiesel has been industrially adopted due to its high conversion rates and low production time. However, this process suffers from several inherent drawbacks related to energy-intensive and environmentally unfriendly processing steps such as catalyst and product recovery, and waste water treatment. This has led to the development of the immobilized enzyme catalyzed process for biodiesel production which is characterized by certain environmental and economical advantages over the conventional chemical method. These include room-temperature reaction conditions, elimination of treatment costs associated with recovery of chemical…
Hysteroscopic Evaluation of Endometrial Changes in Breast Cancer Women with or without Hormone Therapies: Results from a Large Multicenter Cohort Stu…
2020
ABSTRACT Study Objective The primary aim of our study was to investigate the incidence of endometrial pathologies, especially endometrial cancer, in women with breast cancer treated with tamoxifen (TAM), aromatase inhibitors (AIs), or receiving no treatment (NT). The secondary aim was to identify, in this cohort, ultrasonographic findings that represent robust indications for hysteroscopy and endometrial biopsy, to avoid unnecessary second-level diagnostic procedures. Design Multicenter retrospective cohort study (Clinical Trial ID: NCT03898947). Setting Data were collected from different Italian centers: Regina Elena National Cancer Institute of Rome, Arbor Vitae Centre of Rome, Gaetano Ma…
Acute Metabolic Response, Energy Expenditure, and EMG Activity in Sitting and Standing
2017
Purpose While merely standing up interrupts sedentary behavior, it is important to study acute metabolic responses during single bouts of sitting and standing to understand the physiological processes affecting the health of office workers. Methods Eighteen healthy middle-age women 49.4 ± 7.9 yr old (range: 40–64) with a body mass index of 23.4 ± 2.8 kg·m−2 volunteered for this laboratory-based randomized crossover trial where they performed 2 h desk work in either sitting or standing postures after overnight fasting. Muscle activity (normalized to walking at 5 km·h−1), respiratory gas exchange, and blood samples were assessed after glucose loading (75 g). Results Compared with seated work,…
Hemmung der Fettsäureoxydation als ein Faktor bei der antiketogenen Wirkung von Zuckern und Polyalkoholen
1966
Die Wirkung von Fructose, Glucose, Sorbit, Xylit, Ribit und Glycerin auf die Oxydation von14C-Palmitinsaure durch gesunde und diabetische Ratten wurde untersucht. Die uber die Norm gesteigerte Fettsaureoxydation bei diabetischen Tieren wird durch Dauerinfusion aller untersuchten Kohlenhydrate mit Ausnahme von Glucose signifikant gehemmt. Die starkste Wirkung hat Sorbit; dann folgen Xylit, Fructose und Glycerin; Ribit hat die schwachste Wirkung.

Immunelectronmicroscopic characterization of T4 and T8 lymphocytes and natural killer cells in neuronal ceroid-lipofuscinosis.
1995
CD4+, CD8+, and CD56+ cells were isolated with the immunomagnetic separation technique from peripheral blood mononuclear cells (PBMC) of 3 patients with neuronal ceroid-lipofuscinosis : one patient each with infantile (INCL), late infantile (LINCL), and juvenile (JNCL) neuronal ceroid-lipofuscinoses, all studied by light (LM) and electron (EM) microscopy. To compare the pathology of these cells with affected cells in other types of lysosomal diseases, the separation was also performed with PBMC of 1 patient with mucolipidosis (ML) type II, 2 patients with mucopolysaccharidosis (MPS) type I, and 4 patients with MPS type III. Disease-specific lysosomal inclusions were identified in CD4+, CD8+…
Characterization of T–cell subclasses and NK–cells in lysosomal disorders by immuno–electron microscopy
1994
Previous studies have shown that B and T lymphocytes are affected in lysosomal disorders. The aim of this study was to investigate the involvement of subclasses of T lymphocytes and natural killer cells in lysosomal diseases. CD4+, CD8+, and CD56+ cells were immunomagnetically separated from peripheral blood mononuclear cells in 10 patients with various lysosomal diseases--including one patient each with infantile, late infantile, and juvenile neuronal ceroid-lipfuscinoses, two patients with mucopolysaccharidosis (MPS) type I and four patients with MPS type III, and one patient with mucolipidosis type II; all lymphocytes were studied by light and electron microscopy. Respective vacuolar or …
