Characterization of Walnut Oil and Evaluation of Its Neuroprotective Effects in an In Vitro Model of Parkinson's Disease.

Parkinson's disease (PD) is a common neurodegenerative disorder marked by the degeneration of dopaminergic neurons and the buildup of α-synuclein aggregates. The current treatments focus on symptom relief, with no drugs available to halt disease progression. This has prompted interest in plant-based extracts as alternative therapies.

Nutritional status and gastroenteropancreatic neuroendocrine neoplasms: lights and shadows with a clinical guide from the NIKE Group.

Neuroendocrine neoplasms (NENs) originating in the gastroenteropancreatic (GEP) tract are rare tumors often associated with significant metabolic disturbances and nutritional challenges. This review explores the intricate relationship between nutritional status and the development, progression, and prognosis of GEP-NENs. Through an extensive literature search encompassing studies up to April 2024, we examined various factors, including obesity, malnutrition, metabolic syndrome and type 2 diabetes mellitus, and their roles in the development and progression of GEP-NENs.

A cross-sectional study on the prevalence of eating disorders in liver transplanted patients with type 2 diabetes and/or overweight/obesity.

Liver transplantation (LT) associates with weight gain and metabolic complications. However, risk of eating disorders post-transplantation and factors influencing their onset remain poorly understood. This study aimed to fill this knowledge gap by characterizing the risk of having eating disorders or Orthorexia Nervosa (ON) according to the EAT-26, BES and Bratman screening questionnaires in 104 liver transplant recipients (mean age 62.

High bone fracture risk in a large modern cohort of liver transplant recipients.

Liver transplantation (LT) has historically been associated with a high prevalence of osteoporosis, but most of the available data date back to late 1990s-early 2000s with limited sample size. Our aim was to assess the prevalence of bone fragility fractures and contributing factors in a large modern cohort of liver transplant recipients. Retrospective study of 429 consecutive patients receiving liver transplantation from 1/1/2010 to 31/12/2015.

Statistical analysis of feature-based molecular networking results from non-targeted metabolomics data.

Feature-based molecular networking (FBMN) is a popular analysis approach for liquid chromatography-tandem mass spectrometry-based non-targeted metabolomics data. While processing liquid chromatography-tandem mass spectrometry data through FBMN is fairly streamlined, downstream data handling and statistical interrogation are often a key bottleneck. Especially users new to statistical analysis struggle to effectively handle and analyze complex data matrices.

Chemical Characterization and Beneficial Effects of Walnut Oil on a Model of Parkinson's Disease.

A nutritional approach could be a promising strategy to prevent or decrease the progression of neurodegenerative disorders such as Parkinson's disease (PD). The neuroprotective role of walnut oil (WO) was investigated in treated with rotenone (Rot), as a PD model, WO, or their combination, and compared to controls. WO reduced mortality and improved locomotor activity impairment after 3 and 7 days, induced by Rot.

Beta-Blockers Lower First Decompensation in Patients With Cirrhosis and Enduring Portal Hypertension After Etiological Treatment.

Background And Aims: Non-selective beta-blockers (NSBBs) can lower the risk of first decompensation in patients with cirrhosis and clinically significant portal hypertension (CSPH) (identified by a hepatic venous pressure gradient ≥10 mm Hg) with active etiology. Our aim was to examine the effect of NSBBs on first decompensation occurrence in patients with cirrhosis and enduring CSPH after etiological treatment.

Methods: Patients with compensated cirrhosis and clinical evidence of CSPH (gastroesophageal varices [GEVs] and/or spontaneous portosystemic collaterals [SPSSs]) after 2 years from etiological treatment.

Performance of spleen stiffness measurement to rule out high-risk varices in patients with porto-sinusoidal vascular disorder.

Background And Aims: Baveno VII consensus suggests that screening endoscopy can be spared in patients with compensated cirrhosis when spleen stiffness measurement (SSM) by vibration-controlled transient elastography (VCTE) is ≤40 kPa as they have a low probability of high-risk varices (HRV). Conversely, screening endoscopy is required in all patients with porto-sinusoidal vascular disorder (PSVD). This study aimed to evaluate the performance of SSM-VCTE to rule out HRV in patients with PSVD and signs of portal hypertension.

Connecting metabolome and phenotype: recent advances in functional metabolomics tools for the identification of bioactive natural products.

Covering: 1995 to 2023Advances in bioanalytical methods, particularly mass spectrometry, have provided valuable molecular insights into the mechanisms of life. Non-targeted metabolomics aims to detect and (relatively) quantify all observable small molecules present in a biological system. By comparing small molecule abundances between different conditions or timepoints in a biological system, researchers can generate new hypotheses and begin to understand causes of observed phenotypes.

The effects of venovenous bypass use in liver transplantation with piggyback technique: a propensity score-weighted analysis.

Venovenous bypass (VVB) use during liver transplantation (LT) is notably variable among the centres and it is actually restricted to surgically complex cases, severely unstable recipients or grafts from high-risk donors. Historically, VVB was associated with the classical LT with caval cross clamping, while not much is known about the safety of this technique applied to piggyback LT. This retrospective observational study evaluated the effects of VVB applied to piggyback LT on mortality, hospital outcomes, postoperative graft and other organ dysfunction.

Trends in liver transplantation for primary sclerosing cholangitis.

Background: Primary sclerosing cholangitis is a cholestatic disease with a low prevalence in Italy. Indications for liver transplantation and the time of listing are not stated.

Aim: We performed a national survey to investigate the listing criteria, comorbidities, and outcomes.

How to use the Contour intrasaccular device: two illustrative cases.

Contour (Stryker, Kalamazoo, MI) is a relatively new endosaccular device for the treatment of intracranial aneurysms.1 2 Its unique cup-like shape permits treatment of most lesions, including wide-necked, irregular, and shallowed-shaped aneurysms. The sizing of the device only requires two parameters: neck size and equatorial plane (width).

The Evolving Landscape of Therapeutics for Epilepsy in Tuberous Sclerosis Complex.

Tuberous sclerosis complex (TSC) is a rare multisystem genetic disorder characterized by benign tumor growth in multiple organs, including the brain, kidneys, heart, eyes, lungs, and skin. Pathogenesis stems from mutations in either the TSC1 or TSC2 gene, which encode the proteins hamartin and tuberin, respectively. These proteins form a complex that inhibits the mTOR pathway, a critical regulator of cell growth and proliferation.

Alpha-Lipoic Acid Reduces Cell Growth, Inhibits Autophagy, and Counteracts Prostate Cancer Cell Migration and Invasion: Evidence from In Vitro Studies.

Alpha-lipoic acid (ALA) is a natural antioxidant dithiol compound, exerting antiproliferative and antimetastatic effects in various cancer cell lines. In our study, we demonstrated that ALA reduces the cell growth of prostate cancer cells LNCaP and DU-145. Western blot results revealed that in both cancer cells, ALA, by upregulating pmTOR expression, reduced the protein content of two autophagy initiation markers, Beclin-1 and MAPLC3.

Antitumor Activity of Axitinib in Lung Carcinoids: A Preclinical Study.

Lung carcinoids (LCs) comprise well-differentiated neuroendocrine tumors classified as typical (TCs) and atypical (ACs) carcinoids. Unfortunately, curative therapies remain elusive for metastatic LCs, which account for 25-30% of cases. This study evaluated the antitumor activity of axitinib (AXI), a second-generation tyrosine kinase inhibitor selectively targeting vascular endothelial growth factor receptors (VEGFR-1, VEGFR-2, VEGFR-3) in human lung TC (NCI-H727, UMC-11, NCI-H835) and AC (NCI-H720) cell lines.

Cabozantinib in neuroendocrine tumors: tackling drug activity and resistance mechanisms.

Neuroendocrine tumors (NETs) are highly vascularized malignancies in which angiogenesis may entail cell proliferation and survival. Among the emerging compounds with antivascular properties, cabozantinib (CAB) appeared promising. We analyzed the antitumor activity of CAB against NETs utilizing in vitro and in vivo models.

Capmatinib-Induced Liver Injury as Emerging Toxicity of MET Inhibitors in Patients With NSCLC Pretreated With Immune Checkpoint Inhibitors.

Safety data on MET inhibitors in patients with advanced NSCLC harboring MET exon 14 mutation and treated with frontline immune checkpoint inhibitors (ICIs) are still limited. Here, we describe clinical characteristics, liver biopsy features, and management of liver injury of two patients with a diagnosis of MET exon 14-mutant NSCLC receiving capmatinib after ICI failure. On the basis of histologic findings and exclusion of other potential causes, a diagnosis of drug-induced liver injury (DILI) associated with portal fibrosis was made in both cases.

A man in his 40s presented to our Hospital with abdominal pain, jaundice, and pruritus. He had a history of Alagille Syndrome treated with cholecystojejunostomy in the neonatal period because of initial misdiagnosis of biliary atresia. Laboratory investigations showed hyperbilirubinemia (total bilirubin 1.

The influence of inflammation and frailty in the aging continuum.

Inflammaging is a low-grade inflammatory state that can be considered an adaptive process aimed at stimulating appropriate anti-inflammatory response. Frailty is determined by the accumulation of molecular and cellular defects accumulated throughout life; therefore, an appropriate frailty computation could be a valuable tool for measuring biological age. This study aims to analyse the association between inflammatory markers and both chronological age "per se" and frailty.
