Abstract
PURPOSE Neuropeptide Y (NPY) is a pleiotropic peptide, which is involved in many biological mechanisms important in regulation of cell growth and survival. The aim of this study was a comprehensive analysis of the NPY system in prostate pathology. METHODS The study was based on immunohistochemical analysis of NPY and its receptors, Y1R, Y2R and Y5R, in tissue samples from benign prostate (BP), primary prostate cancer (PCa) and PCa bone metastases. Tissue microarray (TMA) technique was employed, with analysis of multiple cores from each specimen. Intensity of the immunoreactivity and expression index (EI), as well as distribution of the immunostaining in neoplastic cells and stromal elements were evaluated. Perineural invasion (PNI) and extraprostatic extension (EPE) were areas of special interests. Moreover, a transwell migration assay on the LNCaP PCa cell line was used to assess the chemotactic properties of NPY. RESULTS Morphological analysis revealed homogeneous membrane and cytoplasmic pattern of NPY staining in cancer cells and its membrane localization with apical accentuation in BP glands. All elements of the NPY system were upregulated in pre-invasive prostate intraepithelial neoplasia, PCa and metastases. EI and staining intensity of NPY receptors were significantly higher in PCa then in BP with correlation between Y2R and Y5R. The strength of expression of the NPY system was further increased in the PNI and EPE areas. In bone metastases, Y1R and Y5R presented high expression scores. CONCLUSION The results of our study suggest that the NPY system is involved in PCa, starting from early stages of its development to disseminated states of the disease, and participates in the invasion of PCa into the auto and paracrine matter.

Abstract
BACKGROUND The aim of the study was to investigate the effect of mild cerebral hypoxia on haemoglobin oxygenation (HbO2), cerebrospinal fluid dynamics and cardiovascular physiology. To achieve this goal, four signals were recorded simultaneously: blood pressure, heart rate / electrocardiogram, HbO2 from right hemisphere and changes of subarachnoid space (SAS) width from left hemisphere. Signals were registered from 30 healthy, young participants (2 females and 28 males, body mass index = 24.5 ± 2.3 kg/m2, age 30.8 ± 13.4 years). RESULTS We analysed the recorded signals using wavelet transform and phase coherence. We demonstrated for the first time that in healthy subjects exposed to mild poikilokapnic hypoxia there were increases in very low frequency HbO2 oscillations (< 0.052 Hz) in prefrontal cortex. Additionally, SAS fluctuation diminished in the whole frequency range which could be explained by brain oedema. CONCLUSIONS Consequently the study provides insight into mechanisms governing brain response to a mild hypoxic challenge. Our study supports the notion that HbO2 and SAS width monitoring might be beneficial for patients with acute lung disease.

Abstract
The aim of the study was to compare simultaneously recorded a NIR-T/BSS and NIRS signals from healthy volunteers. NIR-T/BSS is a device which give an ability to non-invasively detect and monitor changes in the subarachnoid space width (SAS). Experiments were performed on a group of 30 healthy volunteers (28 males and 2 females, age 30.8 ± 13.4 years, BMI = 24.5 ± 2.3 kg/m2). We analysed recorded signals using analysis methods based on wavelet transform (WT) for the wide frequency range from 0.0095 to 2 Hz. Despite the fact that both devices use a similar radiation source both signals are distinct from each other. We found statistically significant differences for WT amplitude spectra between both signals. Additionally, we showed different relationships of both signals to blood pressure. Collectively, based on the present findings and those of previous studies, we can conclude that the combination of NIR-T/BSS or NIRS signals and time-frequency analysis opens new frontiers in science, and give possibility to understand and diagnosis of various neurodegenerative and ageing related diseases to improve diagnostic procedures and patient prognosis.

Abstract
The purpose of the paper is a functional assessment of post-mastectomy patients who underwent latissimus dorsi breast reconstruction (LDBR), and of healthy women, through an analysis of selected muscle function parameters, including motor control assessment. Twenty participants were included in the study (ten LDBR-procedure individuals and ten healthy controls). The research consisted of a DASH (The Disabilities of the Arm, Shoulder and Hand) questionnaire assessment, shoulder area static assessment, shoulder mobility assessment, latissimus dorsi flexibility assessment and shoulder motor control assessment. LDBR-procedure individuals-when compared to healthy controls-exhibited a decrease in physical aspects of quality of life, shoulder area postural alterations, limitations in shoulder mobility and decrease in shoulder motor control. LDBR procedure may have an influence on limiting shoulder active mobility, as well as on decrease of shoulder motor and postural control. Standard functional assessment diversified on motor control assessment of post-mastectomy patients qualified for the LDBR procedure seems to be necessary.

Abstract
Severe aortic stenosis (AS) is associated with the reduction of muscle mass and may be associated with deterioration of nutritional status. Furthermore, malnourished cardiac patients are characterized by a higher risk of postoperative complications and mortality. The aim of this study was the evaluation and comparison of nutritional status, appetite and body composition in older people with severe aortic stenosis before aortic valve replacement and healthy elderly volunteers. One hundred and one patients, aged >65 years old with severe AS were included in the study. Nutritional status was assessed. Body composition was estimated using bioelectrical impedance analysis. Concentrations of albumin, prealbumin, triglycerides, total cholesterol and C-reactive protein were measured, and a complete blood count was done. About 40% of AS patients were at risk of malnutrition. They had decreased hand grip strength and they lost more body mass than the control group. Malnourished AS patients were older, had lower body mass indexes (BMIs) and lower aortic valve areas in comparison to well-nourished patients. Older AS patients, like their peers, show excessive body mass and, at the same time, the features of malnutrition. They have additional factors such as unintentional weight lost and decreased muscle strength which may be associated with worse outcomes.

Abstract
Background Acute hypoxia exerts strong effects on the cardiovascular system. Heart-generated pulsatile cerebrospinal fluid motion is recognised as a key factor ensuring brain homeostasis. We aimed to assess changes in heart-generated coupling between blood pressure (BP) and subarachnoid space width (SAS) oscillations during hypoxic exposure. Methods Twenty participants were subjected to a controlled decrease in oxygen saturation (SaO2 = 80%) for five minutes. BP and heart rate (HR) were measured using continuous finger-pulse photoplethysmography, oxyhaemoglobin saturation with an ear-clip sensor, end-tidal CO2 with a gas analyser, and cerebral blood flow velocity (CBFV), pulsatility and resistive indices with Doppler ultrasound. Changes in SAS were recorded with a recently-developed method called near-infrared transillumination/backscattering sounding. Wavelet transform analysis was used to assess the relationship between BP and SAS oscillations. Results Gradual increases in systolic, diastolic BP and HR were observed immediately after the initiation of hypoxic challenge (at fifth minute +20.1%, +10.2%, +16.5% vs. baseline, respectively; all P<0.01), whereas SAS remained intact (P = NS). Concurrently, the CBFV was stable throughout the procedure, with the only increase observed in the last two minutes of deoxygenation (at the fifth minute +6.8% vs. baseline, P<0.05). The cardiac contribution to the relationship between BP and SAS oscillations diminished immediately after exposure to hypoxia (at the fifth minute, right hemisphere -27.7% and left hemisphere -26.3% vs. baseline; both P<0.05). Wavelet phase coherence did not change throughout the experiment (P = NS). Conclusions Cerebral haemodynamics seem to be relatively stable during short exposure to normobaric hypoxia. Hypoxia attenuates heart-generated BP SAS coupling.

Abstract
Introduction Treatment of secondary lymphedema still remains an important medical issue. Treatment response is characterized by periodic remission rather than complete recovery. Compression methods currently used as part of complete decongestive therapy vary considerably in efficacy. Manual drainage, bandaging, and compression pumps are ineffective in everyday practice. Positive results have increasingly been reported where compression garments have been used as part of the treatment. This pilot study demonstrates a beneficial effect following the use of compression corsets in the treatment of edema in breast cancer-related lymphedema (BCRL). Material A total of 35 women with BCRL were enrolled. Of these, 29 patients completed the study. Methods Ultrasound (B-mode) was used to evaluate lymphedema in the side of the chest after mastectomy. This test was performed three times at a specific site on the operated side and symmetrically on the opposite side. Subsequently, patients were fit with an appropriate compression corset. The data were then statistically analyzed. Conclusion After the surgical treatment of breast cancer, lymphatic fluid reservoirs may form at the side of the chest. The use of carefully selected compression corsets is an effective treatment for BCRL. Corsets are an important item, which we recommend should be included in compression clothing sets. We anticipate this finding will form the foundation for further work on the use of modern compression garments for the treatment of BCRL as well as contribute to the limited number of published reports that exist on the subject.

Abstract
There is no fully effective treatment for secondary lymphedema. In patients with breast cancer, lymphedema may present immediately after axillary dissection or years later. It typically occurs in a limb (such as an arm), but it can also occur in the torso, especially in breast cancer patients. It is, therefore, essential to prevent or minimize the condition. The currently used compression therapy has varying efficiency. Thus, researchers are still looking for better solutions, especially for primary prevention. The aim of this study was to find whether compression corsets therapy with a class I compression garment could prevent truncal lymphedema on the operated side in females who underwent mastectomy and axillary lymph node dissection as the standard of care for breast cancer treatment without subsequent reconstruction. We also investigated whether this therapy is efficient in prevention and treatment of truncal lymphedema in patients who underwent mastectomy and additional radiotherapy, and finally whether this method could be implemented for pain reduction strategies in this treatment group. The study was carried out in 50 randomly selected breast cancer patients classified by the oncologist as candidates for surgery. The final study was completed in 37 patients who underwent mastectomy and lymphadenectomy. The study group was randomly divided into two subgroups: subgroup G (received compression corsets 1 month following the surgery) and subgroup K (control) in which the patients underwent no physiotherapeutic treatment. The size of truncal lymphedema was measured using ultrasound in presentation B. Measurements were carried out symmetrically on both sides of the chest wall. The patients were examined four times. The follow-up was for 7 months in total. After the second measurement, a randomly selected subgroup of patients received properly fitted compression corsets, which they had to wear throughout the study, whereas the control subgroup had no physiotherapy treatment. The results were statistically analyzed. In both subgroups, we analyzed the reduction of pain using a visual analog scale. The results strongly suggest that when properly fitted, class I compression corsets not only are an effective treatment for lymphedema but also could be used for antiedematous prevention in patients who underwent removal of axillary lymph nodes as well as radiotherapy. Results of these studies have also confirmed that the use of compression corsets could reduce pain associated with surgical treatment of breast cancer.

Abstract
Purpose The aim of the study was to assess changes in subarachnoid space width (sas-TQ), the marker of intracranial pressure (ICP), pial artery pulsation (cc-TQ) and cardiac contribution to blood pressure (BP), cerebral blood flow velocity (CBFV) and cc-TQ oscillations throughout the maximal breath hold in elite apnoea divers. Non-invasive assessment of sas-TQ and cc-TQ became possible due to recently developed method based on infrared radiation, called near-infrared transillumination/backscattering sounding (NIR-T/BSS). Methods The experimental group consisted of seven breath-hold divers (six men). During testing, each participant performed a single maximal end-inspiratory breath hold. Apnoea consisted of the easy-going and struggle phases (characterised by involuntary breathing movements (IBMs)). Heart rate (HR) was determined using a standard ECG. BP was assessed using the photoplethysmography method. SaO2 was monitored continuously with pulse oximetry. A pneumatic chest belt was used to register thoracic and abdominal movements. Cerebral blood flow velocity (CBFV) was estimated by a 2-MHz transcranial Doppler ultrasonic probe. sas-TQ and cc-TQ were measured using NIR-T/BSS. Wavelet transform analysis was performed to assess cardiac contribution to BP, CBFV and cc-TQ oscillations. Results Mean BP and CBFV increased compared to baseline at the end of the easy phase and were further augmented by IBMs. cc-TQ increased compared to baseline at the end of the easy phase and remained stable during the IBMs. HR did not change significantly throughout the apnoea, although a trend toward a decrease during the easy phase and recovery during the IBMs was visible. Amplitudes of BP, CBFV and cc-TQ were augmented. sas-TQ and SaO2 decreased at the easy phase of apnoea and further decreased during the IBMs. Conclusions Apnoea increases intracranial pressure and pial artery pulsation. Pial artery pulsation seems to be stabilised by the IBMs. Cardiac contribution to BP, CBFV and cc-TQ oscillations does not change throughout the apnoea.

Abstract
We report the results of experimental studies on the effects of sample supports in laser desorption/ionization mass spectrometry (LDI-MS). LDI time-of-flight (TOF) mass spectra obtained for C(60) and insulin samples deposited onto standard stainless steel substrate and/or onto some non-metallic materials (glass, scotch tape, floppy disc foil, Teflon foil, photocopy film), all recorded under identical, typical experimental conditions, have been compared with regard to their intensity and quality. The LDI investigations show that compared with stainless steel, glass and floppy disc foil sample supports boost (2-3.5 times) ion yields for C(60)(+) and C(60)(-) ions, respectively. The stainless steel and scotch tape sample supports are the best for the mass resolution of positive ions and the formation of (C(60))(n)(-) (n <or= 4) cluster ions, respectively. In the case of detection of insulin by matrix-assisted laser desorption/ionization (MALDI) we did not observe significant differences in sensitivity for the support materials tested. A mechanism of ion formation in the desorption plume is suggested.
