AbstraktW państwach rozwiniętych i rozwijających się coraz większą grupę społeczeństw stanowią seniorzy.Świadomość problemu spowodowała podjęcie powszechnej dyskusji ekspertów i praktyków z dziedzin medycznych na temat konieczności działań niezbędnych dla zapewnienia społeczeństwom pomyślnej starości.Od dawna wskazuje się, że brak aktywności ruchowej jest dla zdrowia niebezpieczny.Starzeniu się układu sercowo-naczyniowego towarzyszy dużo niekorzystnych zmian strukturalnych, czynnościowych i biochemicznych. Za typowe dla tego okresu zmiany uważa się osłabienie możliwości relaksacji włókien mięśniowych, co może być przyczyną rozkurczowej niewydolności serca.Trening zdrowotny – jest rodzajem aktywności fizycznej wykonywanej z powodów medycznych. Celem jest uzyskanie efektów fizycznych oraz psychicznych przeciwdziałających zmniejszaniu się zdolności adaptacyjnych organizmu.Eksperci przekonują osoby starsze o korzyściach płynących z aktywnego fizycznie stylu życia. Bogate piśmiennictwo poruszające tematykę medycznych aspektów procesu starzenia, mówi o niezaprzeczalnym znaczeniu ruchu dla toczących się w ludzkim ciele procesów inwolucyjnych. Aktywność fizyczna odpowiednio dozowana jest w stanie wyraźnie zmniejszyć negatywny wpływ tych zmian i jak najdłużej pozwolić utrzymać zdrowie fizyczne, psychiczne i społeczne. Zauważono, że systematycznie dozowany wysiłek fizyczny zmniejsza ryzyko wystąpienia wielu chorób np. cukrzycy, miażdżycy, choroby niedokrwiennej serca.Liczne badania naukowe i bogate piśmiennictwo gerontologiczne przedstawiają najnowsze doniesienia specjalistów o tym, jak należy prawidłowo przygotować i prowadzić trening fizyczny z osobami starszymi. Ludzki organizm zaczyna starzeć się około 20-25 roku życia. Zmiany dotyczą wszystkich układów ciała. Najbardziej odczuwalne w życiu codziennym są te, które zachodzą w układzie krążeniowo-oddechowym i mięśniowo-szkieletowym. Trening fizyczny dla osoby starszej, aby był skuteczny i bezpieczny, powinien być skonstruowany i nadzorowany przez specjalistę. AbstractIn developed and developing countries an increasing group of societies are seniors. Awareness of the problem has led to widespread discussion of experts and practitioners from the fields of medical devices on the need for the measures necessary to ensure that societies successful old age. For a long time, indicates that the lack of motor activity is dangerous to health. Aging of the cardiovascular system is accompanied by a lot of adverse structural changes and biochemical function.For typical of this period of change is believed to be weakening the possibility of relaxation of the muscle fibers, which may cause diastolic heart failure. Training of health-is a type of physical activity performed for medical reasons. The goal is to get mental and physical effects against reducing the adaptability of the body. Experts are finding older people about the benefits of a physically active lifestyle. Rich writing evocative theme of medical aspects of the aging process, speaks of undeniable importance for traffic in human flesh involutional processes. Physical activity appropriately dosed is able to clearly reduce the negative impact of these changes and as long as you can afford to maintain the physical, mental and social health. It was noted that systematically dosed exercise reduces the risk of many diseases, eg. diabetes mellitus, atherosclerosis, coronary heart disease.Numerous scientific studies and extensive external links gerontologiczne submit the latest reports of professionals about how to properly prepare and conduct physical training with the elderly. The human body begins to age about 20-25 years of age. The changes apply to all body systems. Most felt in everyday life are the ones that occur in the breathing cardiopulmonary and musculo-skeletal. Physical training for older persons, in order to be effective and safe, should be designed and supervised by a specialist
Direction-sensitive graphene flow sensor
Graphene flow sensors hold great prospects for applications, but also
encounter many difficulties, such as unwanted electrochemical phenomena, low
measurable signal and limited dependence on the flow direction. This study
proposes a novel approach allowing for the detection of a flow
direction-dependent electric signal in aqueous solutions of salts, acids and
bases. The key element in the proposed solution is the use of a reference
electrode which allows external gating of the graphene structure. Using
external gating enables to enhance substantially the amplitude of the
flow-generated signal. Simultaneous measurement of the reference electrode
current allows us to recover a flow-direction-sensitive component of the
flow-induced voltage in graphene. The obtained results are discussed in terms
of the Coulomb interaction and other phenomena which can be present at the
interface of graphene with the aqueous solution.Comment: 7 pages, 6 figure
Thermal diffusivity, effusivity and conductivity of CdMnTe mixed crystals
Cd1-xMnxTe mixed crystals belong to a class of materials called ‘‘semimagnetic semiconductor’’ or diluted magnetic semiconductor (DMS) with addition of magnetic ions like Mn2+ implemented into crystal structure. The crystals under investigation were grown from the melt by the high pressure high temperature modified Bridgman method in the range of composition 0 < x < 0.7. Thermal properties of these compounds have been investigated by means of photopyroelectric (PPE) calorimetry in both, back and front detection configuration. The values of the thermal diffusivity and effusivity were derived from experimental data. Thermal conductivity of the specimens was calculated from the simple theoretical dependencies between thermal parameters. The influence of Mn concentration on thermal properties of Cd1-xMnxTe crystals have been presented and discussed
Detection of hydrogen fluoride absorption in diffuse molecular clouds with Herschel/HIFI: a ubiquitous tracer of molecular gas
We discuss the detection of absorption by interstellar hydrogen fluoride (HF)
along the sight line to the submillimeter continuum sources W49N and W51. We
have used Herschel's HIFI instrument in dual beam switch mode to observe the
1232.4762 GHz J = 1 - 0 HF transition in the upper sideband of the band 5a
receiver. We detected foreground absorption by HF toward both sources over a
wide range of velocities. Optically thin absorption components were detected on
both sight lines, allowing us to measure - as opposed to obtain a lower limit
on - the column density of HF for the first time. As in previous observations
of HF toward the source G10.6-0.4, the derived HF column density is typically
comparable to that of water vapor, even though the elemental abundance of
oxygen is greater than that of fluorine by four orders of magnitude. We used
the rather uncertain N(CH)-N(H2) relationship derived previously toward diffuse
molecular clouds to infer the molecular hydrogen column density in the clouds
exhibiting HF absorption. Within the uncertainties, we find that the abundance
of HF with respect to H2 is consistent with the theoretical prediction that HF
is the main reservoir of gas-phase fluorine for these clouds. Thus, hydrogen
fluoride has the potential to become an excellent tracer of molecular hydrogen,
and provides a sensitive probe of clouds of small H2 column density. Indeed,
the observations of hydrogen fluoride reported here reveal the presence of a
low column density diffuse molecular cloud along the W51 sight line, at an LSR
velocity of ~ 24kms-1, that had not been identified in molecular absorption
line studies prior to the launch of Herschel.Comment: 4 pages, 3 figures, A&A Letter special issue, accepted on 07/13/201
Nitrogen hydrides in interstellar gas: Herschel/HIFI observations towards G10.6-0.4 (W31C)
The HIFI instrument on board the Herschel Space Observatory has been used to
observe interstellar nitrogen hydrides along the sight-line towards G10.6-0.4
in order to improve our understanding of the interstellar chemistry of
nitrogen. We report observations of absorption in NH N=1-0, J=2-1 and ortho-NH2
1_1,1-0_0,0. We also observed ortho-NH3 1_0-0_0, and 2_0-1_0, para-NH3 2_1-1_1,
and searched unsuccessfully for NH+. All detections show emission and
absorption associated directly with the hot-core source itself as well as
absorption by foreground material over a wide range of velocities. All spectra
show similar, non-saturated, absorption features, which we attribute to diffuse
molecular gas. Total column densities over the velocity range 11-54 km/s are
estimated. The similar profiles suggest fairly uniform abundances relative to
hydrogen, approximately 6*10^-9, 3*10^-9, and 3*10^-9 for NH, NH2, and NH3,
respectively. These abundances are discussed with reference to models of
gas-phase and surface chemistry.Comment: 5 pages, 3 figures, 2 online pages with 2 figures. Accepted for

Excitation and Abundance of C3 in star forming cores:Herschel/HIFI observations of the sight-lines to W31C and W49N
We present spectrally resolved observations of triatomic carbon (C3) in
several ro-vibrational transitions between the vibrational ground state and the
low-energy nu2 bending mode at frequencies between 1654-1897 GHz along the
sight-lines to the submillimeter continuum sources W31C and W49N, using
Herschel's HIFI instrument. We detect C3 in absorption arising from the warm
envelope surrounding the hot core, as indicated by the velocity peak position
and shape of the line profile. The sensitivity does not allow to detect C3
absorption due to diffuse foreground clouds. From the column densities of the
rotational levels in the vibrational ground state probed by the absorption we
derive a rotation temperature (T_rot) of ~50--70 K, which is a good measure of
the kinetic temperature of the absorbing gas, as radiative transitions within
the vibrational ground state are forbidden. It is also in good agreement with
the dust temperatures for W31C and W49N. Applying the partition function
correction based on the derived T_rot, we get column densities N(C3)
~7-9x10^{14} cm^{-2} and abundance x(C3)~10^{-8} with respect to H2. For W31C,
using a radiative transfer model including far-infrared pumping by the dust
continuum and a temperature gradient within the source along the line of sight
we find that a model with x(C3)=10^{-8}, T_kin=30-50 K, N(C3)=1.5 10^{15}
cm^{-2} fits the observations reasonably well and provides parameters in very
good agreement with the simple excitation analysis.Comment: Accepted for publication in Astronomy and Astrophysics (HIFI first

Gene expression meta-analysis of Parkinson’s disease and its relationship with Alzheimer’s disease
Abstract Parkinson’s disease (PD) and Alzheimer’s disease (AD) are the most common neurodegenerative diseases and have been suggested to share common pathological and physiological links. Understanding the cross-talk between them could reveal potentials for the development of new strategies for early diagnosis and therapeutic intervention thus improving the quality of life of those affected. Here we have conducted a novel meta-analysis to identify differentially expressed genes (DEGs) in PD microarray datasets comprising 69 PD and 57 control brain samples which is the biggest cohort for such studies to date. Using identified DEGs, we performed pathway, upstream and protein-protein interaction analysis. We identified 1046 DEGs, of which a majority (739/1046) were downregulated in PD. YWHAZ and other genes coding 14–3-3 proteins are identified as important DEGs in signaling pathways and in protein-protein interaction networks (PPIN). Perturbed pathways also include mitochondrial dysfunction and oxidative stress. There was a significant overlap in DEGs between PD and AD, and over 99% of these were differentially expressed in the same up or down direction across the diseases. REST was identified as an upstream regulator in both diseases. Our study demonstrates that PD and AD share significant common DEGs and pathways, and identifies novel genes, pathways and upstream regulators which may be important targets for therapy in both diseases
