Exercise training and detraining process affects plasma adiponectin level in healthy and spontaneously hypertensive rats
BACKGROUND: Adiponectin levels with long-term swimming exercise have been never investigated in spontaneously hypertensive rats (SHR). OBJECTIVE: This study was aimed to investigate the effects of exercise and detraining process on the adiponectin plasma levels of spontaneously hypertensive rats (SHR) and healthy Wistar-Kyoto rats (WKY). MATERIAL AND METHODS: The rats in the exercise groups were swimming for 10 weeks, 5 days/week, one hour in a day. The detraining rats were left to be sedentary in their cages for 5 weeks after 10 weeks of exercise period. RESULTS: The plasma adiponectin levels decreased in E and SHRE groups compared to the SC and the SHR groups, respectively. In addition, blood pressure was decreased in the exercise groups vs their controls. The adiponectin level was not found to be significantly different in ED and SHRED groups compared to their controls. The blood pressure did not differ between SDC and ED groups, although in the SHRED group it was found to be lower than in SHRSD group rats. CONCLUSION: The results of this study showed that exercise reduced plasma levels of adiponectin in healthy and spontaneously hypertensive rats. However, this difference disappeared at the end of the training processes. Our results suggest, that changes in plasma adiponectin levels are not responsible for changes in blood pressure
Multivariate Control Charts for Attribute Data
In this paper the use of multivariate control charts for attribute data is proposed. These charts are based on chi-square statistics. Data from various categories can be summarized into a multivariate statistic, i.e., the chi-square statistic, and then the process can be monitored by plotting this statistic on a control chart. A numerical example is provided
Kalmyk traditional medicine: a historical and cultural analysis
The article discusses the features of traditional Kalmyk medicine. The relevance of the research topic matches the growing interest in traditional medicine, and in the spiritual heritage of the Buddhist East. Kalmyk folk medicine is known to have its historical roots going back to the ancient traditions of the nomads of Central Asia. The ancestors of the Kalmyks, the Oirats, had centuries-old traditions of traditional nomadic medicine. In the 17 century, Tibetan medicine, alongside with Buddhist culture, began to reach the Kalmyks. The famous figure of Oriental Enlightenment, Zaya-pandita Namka Jamtso (1599–1662), translated from Tibetan into Oirat language the medical treatise “Gyushi”, which is considered the main source of Tibetan medicine. However, the mass spread of Tibetan medicine over the territory of Kalmykia began only in the 18th century, along with the opening of the first medical khurul.
As a result, Kalmyk traditional medicine moved towards a kind of synthesis of Kalmyk folk medicine, on the one hand, and of Tibetan medicine, on the other. Kalmyk doctors (Emchi) were familiar with both traditions and used them in their medical practice. They could diagnose and treat a fairly considerable number of types of diseases. At the same time, phytotherapy was the most common form of treatment. An important place was occupied by various natural minerals. During the treatment of the patient, fermented milk products (koumiss and chigyan) and a therapeutic diet were widely used. Non-drug treatment included bone-cutting, massage, gymnastics, hydrotherapy, acupuncture, bloodletting, and cauterization.
The tragic events of the first half of the twentieth century, including Russian Civil War and World War II, repressions against the clergy and the deportation of Kalmyks led to the decline of traditional Kalmyk medicine. Currently, in Kalmykia, as well as in other regions of Russia, centers of Tibetan medicine are being opened. It is thus especially important to develop a state policy and put in place control mechanisms to control the revival and practice of traditional medicine in Kalmykia, as well as to set up an information database of resource in traditional medicine, including its intellectual and natural resources, to conduct research and integrate traditional medicine into the public healthcare
Virtual Noncontrast Abdominal Imaging with Photon-counting Detector CT.
Background Accurate CT attenuation and diagnostic quality of virtual noncontrast (VNC) images acquired with photon-counting detector (PCD) CT are needed to replace true noncontrast (TNC) scans. Purpose To assess the attenuation errors and image quality of VNC images from abdominal PCD CT compared with TNC images. Materials and Methods In this retrospective study, consecutive adult patients who underwent a triphasic examination with PCD CT from July 2021 to October 2021 were included. VNC images were reconstructed from arterial and portal venous phase CT. The absolute attenuation error of VNC compared with TNC images was measured in multiple structures by two readers. Then, two readers blinded to image reconstruction assessed the overall image quality, image noise, noise texture, and delineation of small structures using five-point discrete visual scales (5 = excellent, 1 = nondiagnostic). Overall image quality greater than or equal to 3 was deemed diagnostic. In a phantom, noise texture, spatial resolution, and detectability index were assessed. A detectability index greater than or equal to 5 indicated high diagnostic accuracy. Interreader agreement was evaluated using the Krippendorff α coefficient. The paired t test and Friedman test were applied to compare objective and subjective results. Results Overall, 100 patients (mean age, 72 years ± 10 [SD]; 81 men) were included. In patients, VNC image attenuation values were consistent between readers (α = .60), with errors less than 5 HU in 76% and less than 10 HU in 95% of measurements. There was no evidence of a difference in error of VNC images from arterial or portal venous phase CT (3.3 HU vs 3.5 HU, P = .16). Subjective image quality was rated lower in VNC images for all categories (all, P < .001). Diagnostic quality of VNC images was reached in 99% and 100% of patients for readers 1 and 2, respectively. In the phantom, VNC images exhibited 33% higher noise, blotchier noise texture, similar spatial resolution, and inferior but overall good image quality (detectability index >20) compared with TNC images. Conclusion Abdominal virtual noncontrast images from the arterial and portal venous phase of photon-counting detector CT yielded accurate CT attenuation and good image quality compared with true noncontrast images. © RSNA, 2022 Online supplemental material is available for this article See also the editorial by Sosna in this issue
SYNTHESYS+ Virtual Access - Report on the Ideas Call (October to November 2019)
The SYNTHESYS consortium has been operational since 2004, and has facilitated physical access by individual researchers to European natural history collections through its Transnational Access programme (TA). For the first time, SYNTHESYS+ will be offering virtual access to collections through digitisation, with two calls for the programme, the first in 2020 and the second in 2021. The Virtual Access (VA) programme is not a direct digital parallel of Transnational Access - proposals for collections digitisation will be prioritised and carried out based on community demand, and data must be made openly available immediately. A key feature of Virtual Access is that, unlike TA, it does not select the researchers to whom access is provided. Because Virtual Access in this way is new to the community and to the collections-holding institutions, the SYNTHESYS+ consortium invited ideas through an Ideas Call, that opened on 7th October 2019 and closed on 22nd November 2019, in order to assess interest and to trial procedures. This report is intended to provide feedback to those who participated in the Ideas Call and to help all applicants to the first SYNTHESYS+Virtual Access Call that will be launched on 20th of February 2020.This is an open access article distributed under the terms of the Creative Commons Attribution License (CC BY 4.0), which permits unrestricted use, distribution, and reproduction in any medium, provided the original author and source are credited.

Combined distributed turbo coding and space frequency block coding techniques
The distributed space-time (frequency) coding and distributed channel turbo coding used independently represent two cooperative techniques that can provide increased throughput and spectral efficiency at an imposed maximum Bit Error Rate (BER) and delay required from the new generation of cellular networks. This paper proposes two cooperative algorithms that employ jointly the two types of techniques, analyzes their BER and spectral efficiency performances versus the qualities of the channels involved, and presents some conclusions regarding the adaptive employment of these algorithms. © 2010 V.
