Abstract
Glioblastoma (GBM) is the most malignant form of primary brain tumor. It is characterized by the presence of highly invasive cancer cells infiltrating the brain by hijacking neuronal mechanisms and interacting with non-neuronal cell types, such as astrocytes and endothelial cells. To enter the interstitial space of the brain parenchyma, GBM cells significantly shrink their volume and extend the invadopodia and lamellipodia by modulating their membrane conductance repertoire. However, the changes in the compartment-specific ionic dynamics involved in this process are still not fully understood. Here, using noninvasive perforated patch-clamp and live imaging approaches on various GBM cell lines during a wound-healing assay, we demonstrate that the sodium-calcium exchanger (NCX) is highly expressed in the lamellipodia compartment, is functionally active during GBM cell migration, and correlates with the overexpression of large conductance K+ channel (BK) potassium channels. Furthermore, a NCX blockade impairs lamellipodia formation and maintenance, as well as GBM cell migration. In conclusion, the functional expression of the NCX in the lamellipodia of GBM cells at the migrating front is a conditio sine qua non for the invasion strategy of these malignant cells and thus represents a potential target for brain tumor treatment.

Abstract
A growing number of studies is focusing on the pharmacology and feasibility of bioactive compounds as a novel valuable approach to target a variety of human diseases related to neurological degeneration. Among the group of the so-called medicinal mushrooms (MMs), Hericium erinaceus has become one of the most promising candidates. In fact, some of the bioactive compounds extracted from H. erinaceus have been shown to recover, or at least ameliorate, a wide range of pathological brain conditions such as Alzheimer's disease, depression, Parkinson's disease, and spinal cord injury. In a large body of in vitro and in vivo preclinical studies on the central nervous system (CNS), the effects of erinacines have been correlated with a significant increase in the production of neurotrophic factors. Despite the promising outcome of preclinical investigations, only a limited number of clinical trials have been carried out so far in different neurological conditions. In this survey, we summarized the current state of knowledge on H. erinaceus dietary supplementation and its therapeutic potential in clinical settings. The bulk collected evidence underlies the urgent need to carry out further/wider clinical trials to prove the safety and efficacy of H. erinaceus supplementation, offering significant neuroprotective applications in brain pathologies.

Abstract
A retrospective study has been performed on 155 cases of surgically treated hypopharyngeal carcinomas in order to bring to light what effect the type of surgery has on survival and the reasons for failure. The following operations were performed: 103 hemipharyngectomies with total laryngectomy (HPTL); 28 total circular pharyngectomies with total laryngectomy (CPTL); 16 hemipharyngectomies with partial laryngectomy (HPPL); 4 exereses in lateral pharyngectomy; 2 total laryngectomies and 2 hemipharyngectomies in lateral pharyngotomy. Analysis of the results is only performed on the three most numerous groups of patients. The overall neoplastic mortality rate at 5 years was 79% for the HPTL group while it was 50% and 61% in the CPTL and HPPL groups, respectively. The actuarial survival curves show a higher, statistically significant, cumulative 5-year survival rate for the CPTL group (55.9%) than for the HPTL group (30.5%). The authors conclude that, considering the particular submucosa spreading to which hypopharyngeal carcinoma is subject and the good functional recovery which can be obtained with modern reconstructive surgery of the alimentary tract, CPTL should be the treatment of choice, even in the less advanced cases, in order to significantly reduce the risk of local recurrences.

Abstract
Acid phosphatase activity estimated cytochemically is markedly increased in myeloma plasma cells compared to that found in normal plasma cells, polyclonal plasma-cytoses and most interestingly in the non-myelomatous monoclonal dysglobulinaemias. In the differential diagnosis of this last group the test has a useful role.
