We undertook a systematic evaluation of the prognostic value of numerous histologic factors in 165 radical cystectomies (RC) of patients with invasive urothelial carcinoma who underwent surgery after neoadjuvant chemotherapy (NAC). Tumor regression grade (TRG) and therapy-related stromal and epithelial changes were also recorded. Locally advanced disease (≥pT2 and/or pN+) was present in 64% of patients, 22% had no evidence of residual carcinoma (pT0+pN0) and 28% had no evidence of residual muscle invasive carcinoma (≤pT1+N0)...

Transmembrane receptors are usually seen as on and off switch: when the specific ligand is bound, the receptor is on and transduces a downstream signal, while when the ligand is absent, the receptor is off. Over the last two decades several reports have argued from an alternative view where some receptors, depending on the context, will be active both in the presence and in the absence of ligand, being sort of onA and onB switch rather than on and off. These receptors have been named Dependence Receptors (DR) and they share the ability to actively trigger cell death when unbound by their respective ligands...

INTRODUCTION: Calciphylaxis is a rare condition including patchy dermal necrosis that mostly affects chronic hemodialysis patients. The syndrome usually heralds impending death although patients may survive following a set of measures including an adapted dialysis regimen. The present case is a unique patient who recovered from an earlier episode of upper leg calciphylaxis 5 years previously but developed fatal bilateral breast necrosis. PRESENTATION OF CASE: A 69 year old Caucasian woman with a history of atrial fibrillation, hypertension, CVA, hyperparathyroidectomy for secondary hyperparathyroidism and end stage renal disease with hemodialysis recovered in 2012 from extensive symptomatic left upper leg necrosis due to calciphylaxis...

BACKGROUND: Poor medication adherence has been shown to cause medical complications, death, and increased healthcare costs and may be of particular importance in patients with substance use disorder (SUD). Concerns regarding adherence in this population may influence a healthcare provider's decision to prescribe a medication requiring high adherence. Guidance defining best practices that promote adherence among individuals with SUD is lacking. METHODS: A review of English articles in Medline and PsycINFO databases, published between October 1, 1994 and October 31, 2017, was conducted in order to identify studies of interventions intended to improve adherence to oral chronic disease medication regimens among patients with SUD...

New series of triazole-containing 3-phenylcoumarin-lipoic acid conjugates were designed as multi-functional agents for treatment of Alzheimer's disease. The target compounds 4a-o were synthesized via the azide-alkyne cycloaddition reaction and their biological activities were primarily evaluated in terms of neuroprotection against H2 O2 -induced cell death in PC12 cells and AChE/BuChE inhibition. The promising compounds 4j and 4i containing four carbons spacer were selected for further biological evaluations...

Driving under the influence of illicit drugs (DUID) represents a significant menace to public safety and is therefore sanctioned with severe fines and penalties such as driving disqualification or even arrest in case the accident has caused serious injury or death. In Italy, DUID is regulated by the article 187 of the National Street Code, however, the list of the substances to be searched and their threshold concentrations are left to the 20 Italian regional authorities. A further lack of legislative standardization concerns the type of detection methods and moreover the time gap between the car accident and blood sampling...

In the present study, we asked if the different types of stress alter neuronal plasticity markers distinctively in the frontal cortex (FCx) and in the hippocampus (Hp). To do so, we implemented various stress regimens to analyze changes evoked in these rat brain structures. We utilized several molecular techniques, including western blot, ELISA, quantitative RT-PCR, and various biochemical assays, to examine a range of proteins and subjected rats to behavioral tests to evaluate potential maladaptive alterations...

Nonhost resistance is the most common form of disease resistance exhibited by plants against most pathogenic microorganisms. Type I nonhost resistance is symptomless (i.e. no macroscopically visible cell/tissue death), implying an early halt of pathogen growth. The timing/speed of defences is much more rapid during type I nonhost resistance than during type II nonhost and host ("gene-for-gene") resistance associated with a hypersensitive response (localized necrosis, HR). However, the mechanism(s) underlying symptomless (type I) nonhost resistance is not entirely understood...

The cancer-preventive mechanism of selenium should address the way low concentrations of selenometabolites react with cellular targets without being diffused from the sites of generation, the way selenium selectively kills tumor cells, and the intriguing U-shaped curve that is seen with dietary supplementation of selenium and cancer prevention. Protein kinase C (PKC), a receptor for tumor promoters, is well suited for this mechanism. Due to the catalytic redox cycle, low concentrations of methylselenol, a postulated active metabolite of selenium, react with the tumor-promoting lipid hydroperoxide bound to PKC to form methylseleninic acid (MSA), which selectively reacts with thiol residues present within the vicinity of the PKC catalytic domain to inactivate it...

TNF-JNK signaling is one of the highly conserved signaling pathways that regulate a broad spectrum of cellular processes including proliferation and apoptosis. Eiger, the sole homologue of TNF in Drosophila, initiates the TNF-JNK pathway to induce cell death. Previously, Deltex (Dx) has been identified as a Notch signaling component that regulates vesicular trafficking of Notch. In the present study, we have investigated the interaction between these two proteins in order to identify how Dx influences the activity of Eiger...

CONTEXT: MAiD allows a practitioner to administer or prescribe medication for the purpose of ending a patient's life. In 2016, Canada was the latest country, following several European countries and American states, to legalize physician-assisted death. Although some studies report on physician attitudes towards MAiD or describe patient characteristics, there are few that explore the professional challenges faced by physicians who provide MAiD. OBJECTIVES: To explore the professional challenges faced by Canadian physicians who provide MAiD...

Colorectal cancer (CRC) is one of the leading causes of cancer-related deaths worldwide. Similar to many other malignancies, CRC is a heterogeneous disease, making it a clinical challenge for optimization of treatment modalities in reducing the morbidity and mortality associated with this disease. A more precise understanding of the biological properties that distinguish patients with colorectal tumors, especially in terms of their clinical features, is a key requirement towards a more robust, targeted-drug design, and implementation of individualized therapies...

Cardiovascular autonomic neuropathy (CAN) is a well known prognostic marker in diabetes. A large angle between the QRS- and the T-wave vector (QRS-T angle) in the electrocardiogram (ECG) has recently been introduced as another marker of poor prognosis. AIM: To assess and compare the long-term predictive power of the frontal plane QRS-T angle with CAN in people with diabetes. METHODS: In 1992-93 people with diabetes in the municipality of Horsens, Denmark, were identified by the prescription method andan age and gender stratified sample of 240 individuals with diabetes were randomly selected...

The role of CD133 (Prominin-1) as a cancer stem cell marker may be useful for therapeutic approaches and prognostication in prostate cancer patients. We investigated the stem-cell-related function and biological features of a subpopulation of CD133+ cells isolated from established primary human prostate cancer cell lines. The CD133+ cells sorted from human prostate cancer 22Rv1 exhibited high clonogenic and tumorigenic capabilities, sphere forming capacity and serially reinitiated transplantable tumors in NOD-SCID mice...
