MORPHOLOGICAL CHARACTERISTICS OF THE ENDOCRINE FUNCTION OF THE HEART IN COMORBID PATHOLOGY.

Objective: Aim: To study the ultrastructural remodeling of atrial myoendocrine cells (AMC) of the atrial myocardium in streptozotocin-induced diabetes (SID) under chronic immobilization stress (CIS).

Patients And Methods: Materials and methods: 40 sexually mature white male rats (body weight 150-180 g) were included in the study. Four groups were formed: group 1 - animals with comorbid pathology (SID and CIS), group 2 - animals with SID, group 3 - animals with CIS, group 4 - intact animals.

Dental Status and Oral Health Behaviors of Selected 45-74-Year-Old Men from Northeastern Poland.

The aim of this study was to assess the dental status and oral health behaviors of selected 45-74-year-old men from northeastern Poland. A total of 419 men were included. A questionnaire on demographic data, socioeconomic status and oral health behaviors was conducted.

Clinical Ethics Consultation and the Reframing of Risk.

As a clinical ethics consultant, I've received numerous consultation requests from health-care providers that reflect the tension at the heart of the concept of dignity of risk, often presented in this form: "The patient wants to [do something that we think is unsafe]. How can we change their mind or stop them?" These consultation requests are almost always framed within a medicalized conception of risk: each is presented as a medical provider's concern that a patient's behavior or choice will lead to a specific physiological harm that the medical team wishes to avoid. However, this medicalized perspective neglects the subjective nature of self-determined choices and ignores important aspects of how patients integrate their disability or illness into a broader narrative of how their preferences and actions fit within their self-understanding.

Repair of orbital floor fractures via the transantral approach with osteosynthesis plate.

Introduction: The most common surgical access techniques employed in patients with orbital floor fractures are associated with a risk of complications, such as implant infection, migration, epiphora, lower eyelid retraction, ectropion, diplopia worsening, retrobulbar hematoma, emphysema, "white-eyed" syndrome, enophthalmia relapse, hypoglobus, and persistent diplopia due to periorbital atrophy. Consequently, alternative access techniques precluding these complications have to be found.

Study Objective: To assess the efficacy of transantral approach in the surgical treatment of patients with orbital floor fractures based on results of retrospective analysis of our clinical experience.

Temperature and doping-dependent renormalization effects of the low energy electronic structure of Ba1-xKxFe2As2 single crystals.

We investigate the low energy electronic structure of Ba1-xKxFe2As2 (x=0; 0.3, T_{c}=32 K) single crystals by angle-resolved photoemission spectroscopy with a focus on the renormalization of the dispersion. A kink feature is detected at E approximately 25 meV for the doped compound which vanishes at T=200 K but stays virtually constant when T_{c} is crossed.

The electronic phase diagram of the LaO(1-x)F(x)FeAs superconductor.

The competition of magnetic order and superconductivity is a key element in the physics of all unconventional superconductors, for example in high-transition-temperature cuprates, heavy fermions and organic superconductors. Here superconductivity is often found close to a quantum critical point where long-range antiferromagnetic order is gradually suppressed as a function of a control parameter, for example charge-carrier doping or pressure. It is believed that dynamic spin fluctuations associated with this quantum critical behaviour are crucial for the mechanism of superconductivity.

Optical study of LaO0.9F0.1FeAs: evidence for a weakly coupled superconducting state.

We have studied the reflectance of the recently discovered superconductor LaO0.9F0.1FeAs in a wide energy range from the far infrared to the visible regime.

High-field pauli-limiting behavior and strongly enhanced upper critical magnetic fields near the transition temperature of an arsenic-deficient LaO0.9F0.1FeAs1-delta superconductor.

We report upper critical field Bc2(T) data for disordered (arsenic-deficient) LaO0.9F0.1FeAs1-delta in a wide temperature and magnetic field range up to 47 T.

Field and temperature dependence of the superfluid density in LaFeAsO1-xFx superconductors: a muon spin relaxation study.

We present zero field and transverse field muon spin relaxation experiments on the recently discovered Fe-based superconductor LaFeAsO1-xFx (x=0.075 and x=0.1).

Commensurate spin density wave in LaFeAsO: a local probe study.

We present a detailed study on the magnetic order in the undoped mother compound LaFeAsO of the recently discovered Fe-based superconductor LaFeAsO1-xFx. In particular, we present local probe measurements of the magnetic properties of LaFeAsO by means of 57Fe Mössbauer spectroscopy and muon-spin relaxation in zero external field along with magnetization and resistivity studies. These experiments prove a commensurate static magnetic order with a strongly reduced ordered moment of 0.
