Pain increased the number of free radicals in the body.
Previously, we studied changes mainly in oxygen and nitroxide
free radicals and described these changes relative to the lipids
and saccharides. In this article we focus on changes relative to
proteins. Assessment of AGE products (advanced glycation
end-products) was carried out by measuring fluorescence.
Patients were divided into two groups: 15 patients with acute
pain and 17 patients with chronic pain. Acute pain was
associated with a variety of surgical procedures and patients
were examined before and after surgical procedures. The group
of patients with chronic pain suffered from various types of
chronic pain, but mainly back pain. In patients with acute pain,
total protein (TP) decreased after surgery, as did the level of AGE
and the AGE/TP ratio. Nonetheless, post-operative pain
increased. In patients with chronic pain, neither total protein,
AGE, or AGE/TP changed, despite significant pain relief being
reported after treatment. Changes in proteins, as biochemical
markers, before and after pain treatment did not show any
significant changes. In patients with acute pain, the recorded
changes only lasted for 3-5 days after the operation. While in
chronic pain, there were no significant changes at all. The
assumption that changes in proteins, as biomarkers, would have
the same importance as changes in lipids and saccharides was
not proven.
The aim of this prospective study was the validation of the risk stratification of thyroid nodules using ultrasonography with the American College of Radiology Thyroid Imaging, Reporting and Data System (ACR TI-RADS) and partly in comparison to American Thyroid Association (ATA) guidelines in a secondary referral center. Fine needle aspiration biopsy (FNA) (n=605) and histological examinations (n=63) were the reference standards for the statistical analysis. ACR TI-RADS cut-off value: TR4 with sensitivity 85.7 %, specificity 54.1 %, PPV 58.5 %, accuracy 67.7 % (AUC 0.738; p<0.001). ATA cut-off value: “high suspicion” with sensitivity 80 %, specificity 83.3 %, PPV 80 %, accuracy 81.8 % (AUC 0.800; p=0.0025). 18.4 % nodules (3 malignant) could not be assigned to a proper ATA US pattern group (p<0.0001). Both ACR TI-RADS and ATA have allowed fair selection of nodules requiring FNA with superiority of ACR TI-RADS according to classification of all thyroid nodules to the proper group. According to ACR TI-RADS almost one third of the patients were incorrectly classified with 17.9 % missed thyroid carcinomas, exclusively micropapillary carcinomas, even though, the amount of FNA would be reduced to 48 %., Tereza Grimmichová, Petra Pačesová, Libuše Srbová, Jana Vrbíková, Terezia Havrdová, Martin Hill., and Obsahuje bibliografii
Endemic Sicilian pond turtles Emys trinacris Fritz, Fattizzo, Guicking, Tripepi, Pennisi, Lenk, Joger et Wink were examined for the presence of haemogregarine parasites. The presence of haemogregarines, occurring mainly in the microgametocyte stage (13.2 ± 0.12 μm in length and 6.4 ± 0.52 μm in width), was observed in approximately 9% of the sampled E. trinacris. Based on the observed morphology and on the sequencing of nuclear 18S rDNA, we identified the parasite as Haemogregarina stepanowi Danilewsky, 1885. Morphometric study of uninfected and infected red blood cells has shown that H. stepanowi induces different changes in erythrocyte shape depending on the infective stage. The differential count of leukocytes in specimens infected with H. stepanowi showed no significant difference compared with healthy specimens. However, considering the health problems which might be induced by H. stepanowi in the closely related European pond turtle Emys orbicularis (Linneaus), monitoring of the health status of the infected Sicilian populations of E. trinacris is desirable. The restricted distribution of populations of Emys infected with haemogregarines in Sicily is quite puzzling and the possible human-mediated introduction of the parasite in Sicily is briefly discussed., Vincenzo Arizza, Francesco Sacco, Debora Russo, Rita Scardino, Marco Arculeo, Melita Vamberger, Federico Marrone., and Obsahuje bibliografii
Measurement of the chlorophyll (Chl) a fluorescence rise (FR) under higher exciting irradiance (EI), the O-J-I-P transient, or under lower irradiance, the O-I-P transient, is a routinely used method to access photosystem 2 function in thylakoid membranes of chloroplasts. Our measurements with a suspension of pea thylakoid membranes showed that the relative heights of the J and I steps in the FR depended not only on EI but also on the concentration and thickness of the sample. We explain this effect as a consequence of the gradient of EI within the sample. We tested this suggestion by theoretical simulations of the FR based on the model that was previously used for simulation of the FR considering in addition the gradient of EI within the sample. Our theoretical results correspond well with the experiments. The irradiance gradient effect may influence measured FR significantly and this fact should be taken into consideration in the interpretation of measured FRs. and P. Sušila ... [et al.].
With respect to the history of sciences under communism, we understand the gray zone to mean academic practices originating from the negotiated autonomy of academia and the need to respect scientific values such as objectivity and a critical approach to reality. Our research explores the links between academic communities that were not directly involved in dissident activities but actively supported dissent initiatives (very often for a limited period of time) and were linked to transnational scientific networks or social movements. Specifically, we analyze the involvement of socially engaged scientists employed by the official research institutions in dissident activities related to the environmental sciences.
Daśaharā in Bastar/Jagdalpur has nothing to do with the Rāmāya‚a or the Devīmāhātmya, as elsewhere in India. Here, Danteśvarī, the tutelary goddess of the erstwhile royal family, is at the centre of the festival. Invited by the royal family, goddess Danteśvarī arrives from Dantewā`ā, the former capital of Bastar; many village goddesses of the tribal environment also attend. Smaller or larger silver umbrellas are used to represent the goddesses. Some wooden frames (ā‚gās) are used to represent male gods. The climax of the festival is reached, when Danteśvarī, the guest of honor, arrives together with Māvlī, the tutelary goddess of the earlier dynasty, who is represented by a type of palanquin (`oli). One of the most outstanding features of the festival is the procession of two big wooden chariots, constructed by different groups of divāsis and pulled around a certain quarter of the city by other groups, according to a fixed tradition. In the past, the festival served as the annual means of re-endorsing royal power. Since 1999 the grand-nephew of the last Mahārāja of Bastar has again taken over most of the ritual functions.
Let $X$ be a Banach space with the Grothendieck property, $Y$ a reflexive Banach space, and let $X\check{\otimes}_{\varepsilon} Y$ be the injective tensor product of $X$ and $Y$. \item {(a)} If either $X^{\ast \ast }$ or $Y$ has the approximation property and each continuous linear operator from $X^\ast $ to $Y$ is compact, then $X\check{\otimes}_{\varepsilon} Y$ has the Grothendieck property. \item {(b)} In addition, if $Y$ has an unconditional finite dimensional decomposition, then $X\check{\otimes}_{\varepsilon} Y$ has the Grothendieck property if and only if each continuous linear operator from $X^\ast $ to $Y$ is compact.
Let $\mathcal {N}=N_n(R)$ be the algebra of all $n\times n$ strictly upper triangular matrices over a unital commutative ring $R$. A map $\varphi $ on $\mathcal {N}$ is called preserving commutativity in both directions if $xy=yx\Leftrightarrow \varphi (x)\varphi (y)=\varphi (y)\varphi (x)$. In this paper, we prove that each invertible linear map on $\mathcal {N}$ preserving commutativity in both directions is exactly a quasi-automorphism of $\mathcal {N}$, and a quasi-automorphism of $\mathcal {N}$ can be decomposed into the product of several standard maps, which extains the main result of Y. Cao, Z. Chen and C. Huang (2002) from fields to rings.
