    General anesthesia plays a crucial role in many surgical procedures, and it therefore has an enormous impact on human health. There are no precise measures for maintaining the correct dose of anesthetic, and there is currently no fully reliable instrument to monitor depth of anesthesia. In this paper, a novel approach has been proposed for detecting the changes in synchronism of brain signals, taken from EEG machine. During the effect of anesthesia, there are certain changes in the EEG signals. Those signals show changes in their synchronism. This phenomenon of synchronism can be utilized to study the effect of anesthesia on respiratory parameters like respiration rate etc, and hence the quantity of anesthesia can be regulated, and if any problem occurs in breathing during the effect of anesthesia on patient, that can also be monitored

    Audio, image and video signals produce a vast amount of data. The only solution of this problem is to compress data before storage and transmission. In general there is the three crucial terms as, Bit Rate Reduction, Fast Data Transfer and Reduction in Storage. Rate control is a vigorous factor in video coding. In video communications, rate control must ensure the coded bitstream can be transmitted effectively and make full use of the narrow bandwidth. There are various test models usually suggested by a standard during the development of video codes models in order to video coding which should be suffienciently be efficient based on H.264 at very low bit rate. These models are Test Model Number 5 (TMN5), Test Model Number 8 for H.263, and Verification Model 8 (VM8) for MPEG-4 and H.264 etc. In this work, Rate control analysis for H.264, MPEG-4 performed. For Rate control analysis test model verification model version 8.0 is adopted

    Correlation Between the Estimated and the Measured Serum Apolipoprotein –B100 in Kurd Subjects: A Trend to Establish a New Formula

    Apolipoprotein B100 (ApoB100) provides a good assessment of atherogenic lipoproteins (very low, intermediate, and low-density lipoproteins (VLDL, IDL, and LDL)). There is evidence that polymorphism of ApoB100 was observed in many conditions and it links with obesity, diabetes mellitus hypertension, and chronic inflammation, which could be related to the broad field of the atherothrombotic process, and could be one of the leading causes of coronary artery disease (CAD). It can be computed using a formula that makes use of a measurement of non-high-density lipoprotein levels. This study aimed to derive an estimated equation of ApoB100 from the measured ApoB100 levels specific to the healthy subjects of Kurd race/ethnicity in the Kurdistan region of Iraq taking into consideration the gender-based effect and the status of fasting and postprandial effects. A total number of 45 healthy subjects (23 males and 22 females) were enrolled in the study. The following measurements were achieved: anthropometric indices, blood pressure, lipid profile, including ApoB100, and blood sugar. The biochemical measurements were carried out at fasting and postprandial states. Specific equations were derived for calculating the levels of ApoB100. Significant differences in the anthropometric indices, blood pressure, and lipid profile were observed between males and females. The calculated ApoB100 levels were significantly less than the measured ApoB100 levels in both genders and fasting and postprandial states. The estimated equations for ApoB100 for females have differed from that for males at fasting and postprandial states. The levels of ApoB100 can be determined instead of measuring it in the laboratory by using a specific equation for healthy Kurd people. These equations are gender and race/ethnicity based. The established equation of estimated ApoB100 levels in males differed from that in females which is attributed to the cardio-metabolic factors and higher levels of systolic and mean arterial blood pressures among males. Apo B level is a quantitative index of plasma atherogenic lipids in hypertensive patients who presented with dyslipidemia

    Background Health system planning requires careful assessment of chronic kidney disease (CKD) epidemiology, but data for morbidity and mortality of this disease are scarce or non-existent in many countries. We estimated the global, regional, and national burden of CKD, as well as the burden of cardiovascular disease and gout attributable to impaired kidney function, for the Global Burden of Diseases, Injuries, and Risk Factors Study 2017. We use the term CKD to refer to the morbidity and mortality that can be directly attributed to all stages of CKD, and we use the term impaired kidney function to refer to the additional risk of CKD from cardiovascular disease and gout. Methods The main data sources we used were published literature, vital registration systems, end-stage kidney disease registries, and household surveys. Estimates of CKD burden were produced using a Cause of Death Ensemble model and a Bayesian meta-regression analytical tool, and included incidence, prevalence, years lived with disability, mortality, years of life lost, and disability-adjusted life-years (DALYs). A comparative risk assessment approach was used to estimate the proportion of cardiovascular diseases and gout burden attributable to impaired kidney function. Findings Globally, in 2017, 1·2 million (95% uncertainty interval [UI] 1·2 to 1·3) people died from CKD. The global all-age mortality rate from CKD increased 41·5% (95% UI 35·2 to 46·5) between 1990 and 2017, although there was no significant change in the age-standardised mortality rate (2·8%, −1·5 to 6·3). In 2017, 697·5 million (95% UI 649·2 to 752·0) cases of all-stage CKD were recorded, for a global prevalence of 9·1% (8·5 to 9·8). The global all-age prevalence of CKD increased 29·3% (95% UI 26·4 to 32·6) since 1990, whereas the age-standardised prevalence remained stable (1·2%, −1·1 to 3·5). CKD resulted in 35·8 million (95% UI 33·7 to 38·0) DALYs in 2017, with diabetic nephropathy accounting for almost a third of DALYs. Most of the burden of CKD was concentrated in the three lowest quintiles of Socio-demographic Index (SDI). In several regions, particularly Oceania, sub-Saharan Africa, and Latin America, the burden of CKD was much higher than expected for the level of development, whereas the disease burden in western, eastern, and central sub-Saharan Africa, east Asia, south Asia, central and eastern Europe, Australasia, and western Europe was lower than expected. 1·4 million (95% UI 1·2 to 1·6) cardiovascular disease-related deaths and 25·3 million (22·2 to 28·9) cardiovascular disease DALYs were attributable to impaired kidney function. Interpretation Kidney disease has a major effect on global health, both as a direct cause of global morbidity and mortality and as an important risk factor for cardiovascular disease. CKD is largely preventable and treatable and deserves greater attention in global health policy decision making, particularly in locations with low and middle SDI
