Microglia cells, resident immune cells of the brain, survey brain parenchyma by dynamically extending and retracting their processes. Cl(-) channels, activated in the cellular response to stretch/swelling, take part in several functions deeply connected with microglia physiology, including cell shape changes, proliferation, differentiation and migration. However, the molecular identity and functional properties of these Cl(-) channels are largely unknown. We investigated the properties of swelling-activated currents in microglial from acute hippocampal slices of Cx3cr1 (+/GFP) mice by whole-cell patch-clamp and imaging techniques...

BACKGROUND: Previous studies have provided limited support to the association between tobacco smoking and lymphomas with weak evidence of a dose-response relationship. METHODS: We investigated the relationship between tobacco smoking and risk of non-Hodgkin lymphomas (NHL) and Hodgkin lymphomas (HL) through logistic regression spline models. Data were derived from an Italian hospital-based case-control study (1999-2014), which enrolled 571 NHLs, 188 HLs, and 1004 cancer-free controls...

Cytochrome P450-aromatase catalyzes estrogen biosynthesis from C19 steroids. In the testis, Sertoli cells express P450-aromatase and represent the primary source of estrogen during prepuberal age. This study focused on the effect of simulated microgravity (SM) on aromatase expression in primary mouse Sertoli cells. When cultured in Rotary Cell Culture System (RCCS), Sertoli cells, formed multicellular three dimensional spheroids (3D). Biological properties were first analyzed in terms of viability, cell cycle, expression of cytoskeletal components and growth factors in comparison to Sertoli cells cultured in spheroids at unit gravity (G)...

Here we report the case of a 30-year-old woman with a history of neurofibromatosis type 2 (NF2) who presented with an incidentally discovered pelvic mass on an ultrasound. The identity of the mass remained indeterminate following a CT and MRI, although appendiceal pathology was suspected. An elective laparoscopy and appendectomy were performed without complication and pathology on the specimen demonstrated an appendiceal ganglioneuroma. To our knowledge, there has been no prior documented case of an appendiceal ganglioneuroma in a patient with NF2...

Phosphodiesterases (PDE) hydrolyze both cyclic AMP and GMP (cAMP/cGMP) and are responsible for the regulation of their levels in a multitude of cellular functions. PDE10A is expressed in the brain and is a validated target for both schizophrenia and Huntington disease. Here, we address the identification of novel chemical scaffolds that may bind PDE10A via structure-based drug design. For this task, we use INPHARMA, an NMR-based method that measures protein-mediated interligand NOEs between pairs of weakly, competitively binding ligands...

Reasons for using antipsychotic polypharmacy (APP) in routine clinical practice, despite a potentially unfavorable risk-benefit ratio, are poorly understood. This research aimed to determine (1) if severe courses of schizophrenia were associated with APP and (2) if a schizophrenia-related acute event would predict a switch to APP in the short term. Observational prospective data (at baseline and 6months) were drawn from a French nationwide cohort ("Cohorte Générale Schizophrénie"), which included 1859 inpatients and outpatients with schizophrenia...

Over the years, the silkworm, Bombyx mori, has been manipulated by means of chemical and genetic approaches to improve silk production both quantitatively and qualitatively. The silk is produced by the silk gland, which degenerates quickly once the larva has finished spinning the cocoon. Thus, interfering with this degeneration process could help develop new technologies aimed at ameliorating silk yield. To this end, in this work we studied the cell death processes that lead to the demise of posterior silk gland of B...

The mitogen-activated protein kinase (MAPK) cascade is an intracellular signaling pathway involved in the regulation of cellular proliferation and the survival of tumor cells. Several different mutations, involving BRAF or NRAS, exert an oncogenic effect by activating the MAPK pathway, resulting in an increase in cellular proliferation. These mutations have become targets for new therapeutic strategies in melanoma and other cancers. Selective MEK inhibitors have the ability to inhibit growth and induce cell death in BRAF- and NRAS-mutant melanoma cell lines...

We identified the novel PSEN1 pathogenic mutation M84V in 3 patients belonging to a large kindred affected by autosomal dominant Alzheimer's disease (AD). The clinical phenotype was characterized by early onset dementia in 14 affected subjects over 3 generations. Detailed clinical, imaging and genetic assessment was performed. We highlighted the presence of unusual symptoms such as frontal executive syndrome, psychosis and spastic paraparesis in these patients. Spastic paraparesis has been reported in other PSEN1 mutations in adjacent codons, suggesting that the position of the genetic defect may affect the clinical expression, although this phenotype can occur in mutations throughout the whole PSEN1 gene...

Uterine malignancies account for the majority of gynaecologic cancers. Different treatment options are available depending on histology, disease grade and stage. Hysterectomy is the most frequent surgical procedure. Chemotherapy and radiation therapy (CRT) represents the preferred therapeutic choice for locally advanced uterine and cervical malignancies. Imaging of the female pelvis following these treatments is particularly challenging due to alteration of the normal anatomy. Radiologists should be familiar with both the expected post-treatment imaging findings and the imaging features of possible complications to make the correct interpretation and avoid possible pitfalls...

Immune checkpoint inhibitors have emerged as an effective treatment for several tumor types and their use in clinical practice is expected to further increase in the immediate future. Although these agents are well tolerated, they are associated with a peculiar spectrum of toxicity, which is immune mediated and may potentially affect every organ. However, immune-related adverse events are mostly reversible if promptly diagnosed and adequately treated. Therefore, it is crucial that medical oncologists know how to diagnose and treat immune-related adverse events...

Large bowel perforation is an abdominal emergency that results from a wide range of etiologies. Computed tomography is the most reliable modality in detecting the site of large bowel perforation. The diagnosis is made by identifying direct CT findings such as extraluminal gas or contrast and discontinuity along the bowel wall. Indirect CT findings can help support the diagnosis, and include bowel wall thickening, pericolic fat stranding, abnormal bowel wall enhancement, abscess, and a feculent collection adjacent to the bowel...
