Spinal Metastases in Non-Seminomatous Germ Cell Testicular Tumors: Prognosis and Integrated Therapeutic Approaches-A Systematic Review with an Institutional Case Illustration.

(1) Background: Testicular cancer, although accounting for only 0.5% to 1% of all solid male cancers, is the most common malignancy in males aged 15 to 35 years. Non-seminomatous germ cell tumors (NSGCT) represent nearly half of all testicular germ cell tumors and are associated with a more aggressive clinical course.

Clinical Comparison of Decentration and Tilt Effects in Iris-Claw and Trans-scleral Plug Lenses: Wavefront Analysis With a Pyramidal Sensor Aberrometer.

Purpose: To compare the aberrometric profile of the Artisan Aphakia lens (Opthec BV) and transscleral plug FIL-SSF lens (Soleko) and to assess the impact of tilt and decentration on their optical performance.

Methods: This retrospective observational study was conducted at Azienda Ospedaliera Universitaria Careggi, Florence, Italy, with a consecutive cohort of aphakic eyes undergoing secondary lens implantation with an Artisan or FIL-SSF lens. Wavefront analysis was performed using a pyramidal wavefront-based aberrometer (Osiris-T; CSO).

CAT rs1001179 Single Nucleotide Polymorphism Identifies an Aggressive Clinical Behavior in Chronic Lymphocytic Leukemia.

Chronic lymphocytic leukemia (CLL) is characterized by an extremely variable clinical course. Although several parameters have been shown to be associated with clinical outcomes in patients with CLL, there remains substantial intragroup clinical heterogeneity in otherwise molecularly and staging homogeneous CLL subgroups. We have recently shown that high catalase (CAT) expression identifies patients with an aggressive clinical course and that higher CAT expression is associated with the presence of the rs1001179 single nucleotide polymorphism (SNP) T allele in the CAT promoter.

Key Imaging Factors for Transcatheter Management of Tricuspid Regurgitation: Device and Patient Selection.

The growing awareness of tricuspid regurgitation (TR) and the fast-expanding array of devices aiming to percutaneously repair or replace the tricuspid valve have underscored the central role of multi-modality imaging in comprehensively assessing the anatomical and functional characteristics of TR. Accurate phenotyping of TR, the right heart, and pulmonary vasculature via echocardiography, computed tomography, and, occasionally, cardiovascular magnetic resonance and right heart catheterization is deemed crucial in choosing the most suitable treatment strategy for each patient and achieving procedural success. In the first part of the present review, key imaging factors for patient selection will be discussed.

B-cell receptor signaling activity identifies patients with mantle cell lymphoma at higher risk of progression.

Mantle cell lymphoma (MCL) is an incurable B-cell malignancy characterized by a high clinical variability. Therefore, there is a critical need to define parameters that identify high-risk patients for aggressive disease and therapy resistance. B-cell receptor (BCR) signaling is crucial for MCL initiation and progression and is a target for therapeutic intervention.

Neurological hypertensive emergencies: Correlation of blood pressure values with in-hospital outcomes in ischemic stroke.

Background: Few certainties exist regarding optimal management of Blood Pressure (BP) in the very first hours after an ischemic stroke and many questions remain still unanswered. Our work aimed to evaluate the role of BP and its trend as possible determinants of in-hospital mortality (primary outcome), discharge disabilities and hospitalization length (secondary outcomes) in ischemic stroke patients presented with Hypertensive Emergencies (HE).

Methods: We retrospectively evaluated patients presented to Niguarda Hospital, Emergency Department (ED), from 2015 to 2017 with a neurological ischemic HE.

[Persistent ST-elevation with elevated myocardial necrosis markers: a case of myocardial contusion].

Myocardial contusion is a rare and potentially fatal complication of chest trauma. There is no unique definition for this entity: some authors define myocardial contusion as a mild increase in cardiac biomarkers in the context of chest trauma, while for others the diagnosis requires evidence of pathologic findings at cardiac imaging. Consequently, the real incidence of myocardial contusion remains unknown, varying in reports between 8% and 71%.

Fighting Cardiac Thromboembolism during Transcatheter Procedures: An Update on the Use of Cerebral Protection Devices in Cath Labs and EP Labs.

Intraprocedural stroke is a well-documented and feared potential risk of cardiovascular transcatheter procedures (TPs). Moreover, subclinical neurological events or covert central nervous system infarctions are concerns related to the development of dementia, future stroke, cognitive decline, and increased risk of mortality. Cerebral protection devices (CPDs) were developed to mitigate the risk of cardioembolic embolism during TPs.

RAGE inhibition blunts insulin-induced oncogenic signals in breast cancer.

The receptor for advanced glycation end products (RAGE) is implicated in diabetes and obesity complications, as well as in breast cancer (BC). Herein, we evaluated whether RAGE contributes to the oncogenic actions of Insulin, which plays a key role in BC progression particularly in obese and diabetic patients. Analysis of the publicly available METABRIC study, which collects gene expression and clinical data from a large cohort (n = 1904) of BC patients, revealed that RAGE and the Insulin Receptor (IR) are co-expressed and associated with negative prognostic parameters.

Bi-Caval Valve Implantation to Palliate Symptoms in a Case of Massive Tricuspid Regurgitation.

Severe tricuspid regurgitation is associated with the occurrence of right failure and increased morbidity and mortality. Transcatheter heterotopic bi-caval valve implantation might offer symptom relief in these patients that are often at prohibitive surgical risk.

Lipoprotein(a): Cardiovascular Disease, Aortic Stenosis and New Therapeutic Option.

Atherosclerosis is a chronic and progressive inflammatory process beginning early in life with late clinical manifestation. This slow pathological trend underlines the importance to early identify high-risk patients and to treat intensively risk factors to prevent the onset and/or the progression of atherosclerotic lesions. In addition to the common Cardiovascular (CV) risk factors, new markers able to increase the risk of CV disease have been identified.

The rs1001179 SNP and CpG methylation regulate catalase expression in chronic lymphocytic leukemia.

Chronic lymphocytic leukemia (CLL) is an incurable disease characterized by an extremely variable clinical course. We have recently shown that high catalase (CAT) expression identifies patients with an aggressive clinical course. Elucidating mechanisms regulating CAT expression in CLL is preeminent to understand disease mechanisms and develop strategies for improving its clinical management.

Effect of Magnetic Impurities on Superconductivity in LaH.

Polyhydrides are a novel class of superconducting materials with extremely high critical parameters, which is very promising for sensor applications. On the other hand, a complete experimental study of the best so far known superconductor, lanthanum superhydride LaH , encounters a serious complication because of the large upper critical magnetic field H (0), exceeding 120-160 T. It is found that partial replacement of La atoms by magnetic Nd atoms results in significant suppression of superconductivity in LaH : each at% of Nd causes a decrease in T by 10-11 K, helping to control the critical parameters of this compound.

Phospho-Specific Flow Cytometry Reveals Signaling Heterogeneity in T-Cell Acute Lymphoblastic Leukemia Cell Lines.

Several signaling pathways are aberrantly activated in T-ALL due to genetic alterations of their components and in response to external microenvironmental cues. To functionally characterize elements of the signaling network in T-ALL, here we analyzed ten signaling proteins that are frequently altered in T-ALL -namely Akt, Erk1/2, JNK, Lck, NF-κB p65, p38, STAT3, STAT5, ZAP70, Rb- in Jurkat, CEM and MOLT4 cell lines, using phospho-specific flow cytometry. Phosphorylation statuses of signaling proteins were measured in the basal condition or under modulation with HO, PMA, CXCL12 or IL7.

Enantioselective Cytotoxicity of Chiral Diphosphine Ruthenium(II) Complexes Against Cancer Cells.

The chiral cationic complex [Ru(η -OAc)(CO)((R,R)-Skewphos)(phen)]OAc (2 ), isolated from reaction of [Ru(η -OAc)(η -OAc)(R,R)-Skewphos)(CO)] (1 ) with phen, reacts with NaOPiv and KSAc affording [RuX(CO)((R,R)-Skewphos)(phen)]Y (X=Y=OPiv 3 ; X=SAc, Y=OAc 4 ). The corresponding enantiomers 2 -4 have been obtained from 1 containing (S,S)-Skewphos. Reaction of 2 and 2 with (S)-cysteine and NaPF at pH=9 gives the diastereoisomers [Ru((S)-Cys)(CO)(PP)(phen)]PF (PP=(R,R)-Skewphos 2 -Cys; (S,S)-Skewphos 2 -Cys).

Papillary Thyroid Carcinoma: Molecular Distinction by MicroRNA Profiling.

Papillary thyroid carcinoma (PTC) is a miscellaneous disease with a variety of histological variants, each with its own mutational profile, and clinical and prognostic characteristics. Identification of microRNA (miRNA) expression profiles represents an important benchmark for understanding the molecular mechanisms underlying the biological behavior of these unique PTC subtypes in order that they be better characterized. We considered a series of 35 PTC samples with a histological diagnosis of either hobnail (17 cases) or classical variant (nine cases) and with a specific p.

Puberty onset curve in CD (Sprague Dawley) and Long Evans outbred male rats.

The exact timing of puberty is fundamental in preclinical studies. In male rats, the age at sexual maturity varies considerably between 40 and 60 days of age. Here, we summarize pubertal onset evaluation of two outbred rat strains (Crl:CD(SD) and Crl:LE), relying on the balano-preputial separation test.
