AIM: Differentiating between parathyroid lesions is still difficult and ambiguous. In cases of primary hyperparathyroidism, appropriate and prompt diagnosis is of great importance for effective treatment and follow-up. A great amount of mechanisms contribute to the pathogenesis of primary hyperparathyroidism, such as disturbance in balance between pro- and anti-apoptotic factors. Therefore, we examined whether immunohistochemical expression of apoptotic factors, TNF-related apoptosis-inducing ligand (TRAIL) and Fas, could have clinical utility as a marker of proliferative lesions of parathyroid gland...

BACKGROUND: Rhabdoid meningioma is rare aggressive meningioma histological subtype, which develops predominantly through progression from less malignant tumors. Due to a low incidence the biological background is unknown. The aim of this study was to profile somatic mutations in four meningioma samples from the same patient, derived previously from four subsequent tumor resections. CASE DESCRIPTION: 58-year-old woman suffering from recurrent meningioma progressing from atypical to rhabdoid subtype...

Structured population models, particularly size- or age-structured, have a long history of informing conservation and natural resource management. While size is often easier to measure than age and is the focus of many management strategies, age-structure can have important effects on population dynamics that are not captured in size-only models. However, relatively few studies have included the simultaneous effects of both age- and size-structure. To better understand how population structure, particularly that of age and size, impacts restoration and management decisions, we developed and compared a size-structured integral projection model (IPM) and an age- and size-structured IPM, using a population of Crassostrea gigas oysters in the northeastern Pacific Ocean...

INTRODUCTION: Prostate cancer is the most frequent cancer among males in Europe and a leading cause of cancer deaths, with similar proportion in other developed countries. For more than twenty years, external-beam radiation therapy, alongside with radical prostatectomy, has been used as a primary radical therapeutic approach for localized prostate cancer. Yet, EBRT failures relate to 22-69% following curative radiotherapy (± androgen deprivation therapy). Additionally, a proportion of these men will have a biopsy-proven local recurrence...

INTRODUCTION: Urothelium is a highly specialized type of epithelium covering the interior of the urinary tract. One of the structures responsible for its unique features are urothelial plaques formed from glycoprotein heteropolymers, the uroplakins. Four types of uroplakins are known - UPIa, UPIb, UPII, UPIII. Herein we review the current status of knowledge about uroplakins and discuss their potential clinical applications. MATERIAL AND METHODS: A PubMed search was conducted to find original and review papers about uroplakins...

We recently developed a high intensity one leg dynamic exercise (OLDE) protocol to measure muscle endurance and investigate the central and peripheral mechanisms of muscle fatigue. The aims of the present study were to establish the reliability of this novel protocol and describe the isokinetic muscle fatigue induced by high intensity OLDE and its recovery. Eight subjects performed the OLDE protocol (time to exhaustion test of the right leg at 85% of peak power output) three times over a week period. Isokinetic maximal voluntary contraction torque at 60 (MVC60), 100 (MVC100) and 140 (MVC140) deg/s was measured pre-exercise, shortly after exhaustion (13 ± 4 s), 20 s (P20) and 40 s (P40) post-exercise...

Notch signalling is an evolutionarily conserved signalling pathway, which plays a significant role in a wide array of cellular processes including proliferation, differentiation, and apoptosis. Nevertheless, it must be noted that Notch is a binary cell fate determinant, and its overexpression has been described as oncogenic in a broad range of human malignancies. This finding led to interest in therapeutically targeting this pathway especially by the use of GSIs, which block the cleavage of Notch at the cell membrane and inhibit release of the transcriptionally active NotchIC subunit...

OBJECTIVE: Spinocerebellar ataxia type 1 is an autosomal dominant fatal neurodegenerative disease caused by a polyglutamine expansion in the coding region of ATXN1. We showed previously that partial suppression of mutant ataxin-1 (ATXN1) expression, using virally-expressed RNAi triggers, could prevent disease symptoms in a transgenic mouse model and a knock in mouse model of the disease, using a single dose of virus. Here, we set out to test if RNAi triggers targeting ATXN1 could not only prevent, but also reverse disease readouts when delivered after symptom onset...

CONTEXT: The microphthalmia-associated transcription factor (MITF) regulates the survival, proliferation and differentiation of neural crest-derived lineages. Recent studies reported an increased risk of melanoma in individuals carrying the rare variant MITF, p.E318K (rs149617956). Whether this variant plays a role in other neural-crest derived tumors is unknown. OBJECTIVE: In the present study, we aimed at determining the prevalence of the MITF, p.E318K variant in a well characterized French cohort of pheochromocytomas/paragangliomas (PCC/PGL)...

An acute bout of aerobic exercise induces neuroplasticity in the motor cortex. Moreover, paired associative stimulation (PAS) is known to induce neuroplasticity in M1. However, the possible influence of the type of exercise on the neuroplastic changes remains unknown. The present study investigated the effects of two different modes of muscle contraction produced during locomotor exercise on changes in corticospinal (CS) excitability. Subjects performed two 30-min treadmill exercises at an intensity corresponding to 60% of their maximal heart rate with either a +10% (uphill) or -10% (downhill) slope...

BACKGROUND: Whereas childhood adversity (CA) and the hypothalamus-pituitary-adrenal (HPA) axis have been suggested to play a major role in the etiology of non-suicidal self-injury (NSSI), no study has thus far investigated both its associations and interactions with adolescent NSSI. METHOD: We investigated CA (antipathy, neglect, physical, psychological, and sexual abuse) and indices of HPA axis activity (salivary and hair cortisol) in a clinical sample of 26 adolescents engaging in NSSI and 26 age- and gender-matched healthy controls (HC)...

BACKGROUND Donation after cardiac death offers the possibility of increasing the pool of organs for transplantation by up to 30%. Maastricht category type 3 (M3) dominates in most countries with active DCD programs. During preparations to introduce a permanent program for uncontrolled donation after circulatory death in Szczecin, Poland, the donor pool has been estimated. In Poland, Maastricht category type 2 (M2) is considered a basic source for organ recovery. MATERIAL AND METHODS This was a retrospective cohort study of out-of-hospital cardiac arrests (OHCA) reported to local Emergency Medical Services (EMS) between 1 December 2014 and 30 November 2015...

Descriptive diagnoses of nonsuicidal self-injury (NSSI) and suicide attempts (SAs) may detract from underlying dimensional borderline personality pathology (D-BPP). This study aimed to investigate D-BPP in adolescent inpatients with NSSI and SAs. A consecutive sample of 359 adolescent inpatients was assessed for current and past NSSI and life-time SAs. D-BPP and current mental health problems were measured using the Dimensional Assessment of Personality Pathology and the Strengths and Difficulties Questionnaire, respectively...

We study the poles of the retarded Green's functions of strongly coupled field theories exhibiting a variety of phase structures from a crossover up to a first order phase transition. These theories are modeled by a dual gravitational description. The poles of the holographic Green's functions appear at the frequencies of the quasinormal modes of the dual black hole background. We establish that near the transition, in all cases considered, the applicability of a hydrodynamic description breaks down already at lower momenta than in the conformal case...
