Entinostat Enhances the Efficacy of Chemotherapy in Small Cell Lung Cancer Through S-phase Arrest and Decreased Base Excision Repair

PURPOSE: Acquired chemoresistance is a frequent event in small cell lung cancer (SCLC), one of the deadliest human malignancies. Histone deacetylase inhibitors (HDACi) have been shown to synergize with different chemotherapeutic agents including cisplatin. Accordingly, we aimed to investigate the dual targeting of HDAC inhibition and chemotherapy in SCLC.EXPERIMENTAL DESIGN: The efficacy of HDACi

The age-dependent association of risk factors with pancreatic cancer

BACKGROUND: Pancreatic cancer presents as advanced disease in >80% of patients; yet, appropriate ages to consider prevention and early detection strategies are poorly defined. We investigated age-specific associations and attributable risks of pancreatic cancer for established modifiable and non-modifiable risk factors.PATIENTS AND METHODS: We included 167 483 participants from two prospective US

Beam Loading Studies for Cavity Phase and Amplitude Setting

ESS linjäraccelerator ska korrigera störningar innan de uppstår. I Lund pågår just nu bygget av europas nya anlägg- ning för forskning med neutronspridning, ESS. Neu- tronspridning är en icke-destuktiv metod för att stu- dera rörelser och strukturer på molekylnivå. Meto- den används som komplement till röntgenstrålning. På liknande sett som man med röntgenstrålning kan se igenom huden på en männisThe purpose of this thesis is to study beam-cavity interactions, with a focus on how to maintain an unperturbed acceleration field in a conducting cavity with a proton beam present. The impact on a cavity acceleration field from different perturbation sources is investigated through computer simulations of a theoreti- cal model based on a resonant circuit. Perturbations from the RF input pulse to

Study of the effect of vacuum impregnation with different substances on respiration and color of packed baby spinach leaves.

Vegetables and fruits hold a vast amount of air within their structure. Vacuum impregnation is a process used to remove the air from plant tissues and replace it with an external solution. For impregnation, vacuum is applied to the plant tissue helping air to escape through the plant´s pores. Then by restoring the atmospheric pressure, the solution surrounding the plant will penetrate the plant ti

Integrating Tumor-Intrinsic and Immunologic Factors to Identify Immunogenic Breast Cancers from a Low-Risk Cohort : Results from the Randomized SweBCG91RT Trial

PURPOSE: The local immune infiltrate's influence on tumor progression may be closely linked to tumor-intrinsic factors. The study aimed to investigate whether integrating immunologic and tumor-intrinsic factors can identify patients from a low-risk cohort who may be candidates for radiotherapy (RT) de-escalation.EXPERIMENTAL DESIGN: The SweBCG91RT trial included 1,178 patients with stage I to IIA

Restricted cortical and amygdaloid removal of vesicular glutamate transporter 2 in preadolescent mice impacts dopaminergic activity and neuronal circuitry of higher brain function

A major challenge in neuroscience is to resolve the connection between gene functionality, neuronal circuits, and behavior. Most, if not all, neuronal circuits of the adult brain contain a glutamatergic component, the nature of which has been difficult to assess because of the vast cellular abundance of glutamate. In this study, we wanted to determine the role of a restricted subpopulation of glut

Pharmacokinetics and retrograde spread of budesonide enemas in patients with distal ulcerative colitis

METHODS: The retrograde spread of two budesonide enema formulations with different viscosities was investigated. The study design was open, randomized and two-period crossover. Three female and two male patients (age range: 35-45 years) with distal ulcerative colitis or proctitis participated. Both enema formulations contained a dose of 2 mg budesonide/100 mL. An unabsorbable radioactive marker (9METHODS: The retrograde spread of two budesonide enema formulations with different viscosities was investigated.

A Biological Signature for Breast Ductal Carcinoma In Situ to Predict Radiotherapy Benefit and Assess Recurrence Risk

PURPOSE: Ductal carcinoma in situ (DCIS) patients and their physicians currently face challenging treatment decisions with limited information about the individual's subsequent breast cancer risk or treatment benefit. The DCISionRT biological signature developed in this study provides recurrence risk and predicts radiotherapy (RT) benefit for DCIS patients following breast-conserving surgery (BCS)

Stabilization of evanescent wave propagation operators

This paper presents a stabilized scheme that solves the wave propagation problem in a general bianisotropic, stratified medium. The method utilizes the concept of propagators, i.e., the wave propagation operators that map the total tangential electric and magnetic fields from one plane in the slab to another. The scheme transforms the propagator approach into a scattering matrix form, where a spec

Multiple Forms of Endocannabinoid and Endovanilloid Signaling Regulate the Tonic Control of GABA Release

UNLABELLED: Persistent CB1 cannabinoid receptor activity limits neurotransmitter release at various synapses throughout the brain. However, it is not fully understood how constitutively active CB1 receptors, tonic endocannabinoid signaling, and its regulation by multiple serine hydrolases contribute to the synapse-specific calibration of neurotransmitter release probability. To address this questi

Randomized study on adjuvant chemotherapy in stage I high-risk ovarian cancer with evaluation of DNA-ploidy as prognostic instrument

PURPOSE: Adjuvant chemotherapy versus observation and chemotherapy at progression was evaluated in 162 patients in a prospective randomized multicenter study. We also evaluated DNA-measurements as an additional prognostic factor.PATIENTS AND METHODS: Patients received adjuvant carboplatin AUC 7 every 28 days for six courses (n = 81) or no adjuvant treatment (n = 81). Eligibility included surgicall

Ventricular kinetic energy in young fontan patients

Introduction: Four-dimensional (4D) flow magnetic resonance imaging (MRI) enables kinetic energy (KE) quantification of intraventricular blood flow. In this study we aimed to quantify the KE in in patients with univentricular heart and to assess the change in the KE after different types of interventions. Methods: 4D flow MRI was acquired in patients with Fontan circulation (n=12; median age 12, r
