Background: Histologic grade, completeness of resection, and presence of metastases are traditionally regarded as the primary factors in predicting survival for retroperitoneal soft tissue sarcoma (RPSTS). We sought to examine the importance of histologic type as a prognostic factor among patients with RPSTS.

Methods: We identified 2337 cases of RPSTS in the Surveillance, Epidemiology, and End Results (SEER) database from 1988 to 2004. After excluding 273 cases of age <18, identification by autopsy only, or absence of histologic confirmation, we arrived at a final study cohort of 2064 patients. Overall survival (OS) and disease-specific survival (DSS) were estimated using the Kaplan-Meier method. Multivariate analysis was performed using a Cox proportional hazards model, adjusting for age, gender, race, histologic type, histologic grade, tumor size, extent of resection, and SEER summary stage.

Results: Among 33 histologic types, leiomyosarcoma (28.7%), well-differentiated/dedifferentiated liposarcoma (20.3%), liposarcoma not otherwise specified (NOS) (11.9%), malignant fibrous histiocytoma (MFH-11.0%), and sarcoma NOS (10.7%) were the most prevalent. Grade distribution was low, 24.2%; intermediate, 16%; high 34.3%, and unknown, 25.5%. Surgery was performed in 85.8%, and radiotherapy was administered to 22.8%. With a median follow-up of 38 mo, median OS was 78, 35, 25, 18, and 10 mo for liposarcoma, leiomyosarcoma, other histologies, MFH, and sarcoma NOS, respectively (P < 0.0001). Median DSS was 120, 53, not reached, 30, and 13 mo for liposarcoma, leiomyosarcoma, other histologies, MFH, and sarcoma NOS, respectively (P < 0.0001). On multivariate analysis, histologic type was associated with statistically significant differences in both OS and DSS.

Conclusions: Histologic type is an important predictor of survival in RPSTS.

Aims And Objectives: This study aimed to explore the relationship between HERC6- associated immune response and Non-Alcoholic Fatty Liver Disease (NAFLD) and to screen drug candidates for novel treatments.

Materials And Methods: Mendelian Randomization (MR) was performed to test the relationship between a genetically predicted increase in HERC6 expression and the development of NAFLD. A single-cell RNA-seq profile of liver tissue with histological characteristics (GSE168933) was obtained.

Background: Dementia with Lewy Bodies (DLB) is one of the most common Alzheimer's Disease (AD)-related dementias and it is defined by the presence of abnormal cytoplasmic inclusions composed of aggregated α-synuclein (αsyn) in neuronal soma, known as Lewy bodies (LB). LB often coexists with AD type pathology such as amyloid-β (Aβ) plaques and neurofibrillary tangles containing hyperphosphorylated tau in several LB dementias, including Parkinson's Disease Dementia and Lewy Body variant AD. These co-pathologies likely represent a spectrum of various contributions of shared mechanisms that underlie these diseases.

Background: Progressive supranuclear palsy (PSP) is the most common primary tauopathy, with a constellation of pathological features including 4R-tau positive neurofibrillary tangles and tufted astrocytes. Most PSP cases are sporadic and associated with common structural variation in the 17q21.31 MAPT locus as well as other loci, including EIF2AK3 which is critical for the integrated stress response (ISR).

Background: The role of oligomeric forms of various proteins as direct responsible of neuronal dysfunction in neurodegenerative disorders has been supported by numerous findings at experimental level and, more recently, by histological examinations in human material. The cellular prion protein (PrP) has been proposed to mediate the neurotoxicity of β-amyloid, α-synuclein and tau oligomers. We demonstrated that although amyloid-β oligomers (AβOs) bind with high affinity to PrP, the memory deficit induced by intracerebroventricular (ICV) administration of AβOs in mice was not mediated by PrP.
