Ceramide As A Potential Tumor Marker For Diagnosis Of Prostate Cancer And Its Association With Lipid Profile

Background: Prostate cancer (PCa) is the second most frequent type of malignancy cancer among men worldwide. Ceramides are fatty acid derivatives of sphingoid bases, and formed not only through the de novo biosynthetic pathway, but also from the degradation of glycosphingolipids (GSLs) and ceramide-1-phosphate. Dyslipidaemia is part of metabolic syndrome, characterized by an alteration of the plasma lipid profile, including Cholesterol, HDL, and triglyceride levels. Objective Evaluate serum ceramide as tumer marker of prostate cancer and its association with lipid profile. Method This case- control study was carried out at Department of Biochemistry, College of Medicine, University of Baghdad and at Urology department, Ghazi Al-Hariri Hospital for surgical speciality during the period from March 2022 to May 2023. It included 120 men patients, 60 men patients who newly diagnosed to have primary prostate cancer (PCa), and 60 men were apparently healthy men. Investigations included serum measurements of ceramide by using enzyme linked immunosorbent assay(ELISA) and also measurement of lipid profile by using semi-auto biochemistry  analyzer.Results The results of the present study showed that there was a significant differences in ceramide in prostate cancer patients as compared with the control group The results also showed that the S.Cholesterol, and S.Triglyceride were higher in the patients group compared to the controls group  with significant statistical difference. Conclusion. According to the results obtained we can suggest that higher levels of ceramide, Cholesterol and Triglyceride may be associated with risk of prostate cancer

Simulation-Based Frequentist Inference with Tractable and Intractable Likelihoods

High-fidelity simulators that connect theoretical models with observations are indispensable tools in many sciences. When coupled with machine learning, a simulator makes it possible to infer the parameters of a theoretical model directly from real and simulated observations without explicit use of the likelihood function. This is of particular interest when the latter is intractable. We introduce a simple modification of the recently proposed likelihood-free frequentist inference (LF2I) approach that has some computational advantages. The utility of our algorithm is illustrated by applying it to three pedagogically interesting examples: the first is from cosmology, the second from high-energy physics and astronomy, both with tractable likelihoods, while the third, with an intractable likelihood, is from epidemiology

Disorders of Bulldogs under primary veterinary care in the UK in 2013

The Bulldog is a popular companion breed in the UK despite widely reported disease predispositions. This study aimed to characterise the demography, mortality and common disorders of Bulldogs under veterinary care in the UK during 2013. VetCompass collates anonymised clinical data from UK primary-care veterinary practices for epidemiological research. The clinical records of all Bulldogs available in the VetCompass study dataset were reviewed manually in detail to extract the most definitive diagnoses recorded for all disorders that existed during 2013 and for all deaths. Bulldogs comprised 1621 (0.36%) of 445,557 study dogs. Bulldogs increased from 0.35% of the 2009 birth cohort to 0.60% in 2013. Median longevity was 7.2 years, which was lower in males (6.7 years) than females (7.9 years) (P = 0.021). The most prevalent fine-level precision disorders recorded were otitis externa (n = 206, prevalence 12.7%, 95% CI: 11.1–14.4), pyoderma (142, 8.8%, 95% CI: 7.4–10.2) and overweight/obesity (141, 8.7%, 95% CI: 7.4–10.2). The most prevalent disorder groups were cutaneous (n = 463, prevalence: 28.6%, 95% CI: 26.4–30.8), ophthalmological (292, 18.0%, 95% CI: 16.2–20.0), aural (211, 13.0%, 95% CI: 11.4–14.8), enteropathy (188, 11.6%, 95% CI: 10.1–13.3) and upper respiratory tract (171, 10.5%, 95% CI: 9.1–12.1). Provision of an evidence base on the most common disorders and causes of mortality within breeds can support owners, breeders and the veterinary profession to improve health and welfare within these breed

Molecular Detection of Helicobacter pylori by Real Time- PCR in Dyspeptic Patients

Helicobacter pylori  is one of the most common infection worldwide and is associated with gastric disorders. H. pylori is genetically unstable and this reflected on its virulence factors and type of diseases. Cytotoxin associated gene A (CagA) product is a major virulence factor is thought to be associated with gastric diseases. In the present study, we used RT-PCR for rapid detection of H. pylori infection in peptic ulcer patient, the determination of CagA gene directly from gastric biopsy specimens and determining relationship between gastric cancer and H. pylori. Gastric biopsy were collected from 54 patients with disorders in digestive system from AL-Hussein teaching hospital. The results of  current study showed that the  presence of 16SrRNA for H. pylori was 21(38.9%), 15 of 24(62.5%) were males and 6 of 30(20.0%) were females, whereas the percentage of CagA gene was 18(33.3%), 12 of 24 (50%) were males and 6 of 30 (20%) were females by using Real time quantitative PCR in  54 biopsy specimens. These result revealed a significant difference between males and females. Our study indicated that CagA gene RT-PCR is the most specific for the detection of H. pylori in gastric biopsy specimens in patients with gastric cancer compared with 16SrRNA gene . There were significant differences (p≤0.05) in CagA positive rate, among different diseases. In this study the presence of H. pylori in patients with Gastric cancer and peptic ulcer has been demonstrated by using RT-PCR method to support the hypothesis that H. pylori has a place in etiology of gastric cancer

Study The Proton Momentum Distribution of The 51V (γ,p)50Ti Reaction at Energy of 59.2 Mev

The technique developed by Findlay and Owens for the extraction of a consistently effective momentum distribution from the 51V (γ,p)50Ti reaction data is applied to the cross sections obtained for each of the discrete low lying excited states ( 0.0 , 1.6 , 2.7 , 3.2 , 3.8 , 4.4 and 6.0 ) MeV ,respectively.The momentum density and momentum mismatch have been calculated using the method of Findlay and Owens for each excited state. This program has been written for this purpose using Fortran-77 language.The momentum scaled distribution would illustrate that the simple Direct Knockout Model (DKM) behavior observed in the (γ,p) reaction could be regarded as evidence for the importance of the DKM process in the (γ,p) reaction. Clearly the application of the procedure given by Findlay and Owens leads to a more consistent momentum distributio

Adaptive hybrid technique for face recognition

One of the most important biometric features for personal identification is the face. In current paper, a new method of face verification upon on singular value decomposition (SVD) and standard deviation (SD) would be described. Due to many variations in real-life such as pose, illumination, or facial expression, there would be difficulty of face recognition. It should be mentioned that there are many approaches for face recognition, however, there is no one could be considered as the most suitable for many situations. One of the methods used is Singular value vector for an image detecting, but the drawback of this approach is the low rate of recognition, where one scale singular value vector is used for face acknowledgment. There an algorithm has been developed to expand the rate of the recognition. In this paper, an approach has been proposed to associate two feature sets obtained from SVD and SD method. It has noticed a good recognition rate could be obtained from the experimental results, where approximately more that 97.5% recognition rate has obtained on the ORL data base. The results from current proposed method have matched with some techniques and it has shown that this method is better than the existing approaches. An extensive experiment has demonstrated not only better performance, but it offers a great likely to achieve equivalent performance to other categories of state-of-the-art methods

Histomorphological study of duodenum of goose (Anser anser)

The present work includes anatomical and histological studied of the different part of the duodenum in the Goose (Anser anser). It was taken (10) birds were anaesthesia and work of a longitudinal incision in the abdomen and the eradication of the gut complete manner and then duodenum measurements, Anatomical study shown duodenum divided into three parts ascending, descending and middle part. Histological study after dying in the form of hematoxylin and eosin represent the wall of the duodenum in all parts consist of four-layer tunica mucosa, submucosa, muscularis and serosa. The tunica mucosa of all parts of the duodenum was studied with folded villi of different shape and size, which were lined by simple columnar epithelium having more goblet cells in proximal part in contrast middle and distal part. The goblet cells are distributed between enterocytes and secrete mucus that covers the mucosa. The apical part of villi of proximal duodenum were slightly pointed and the basal parts of villi were thicker than middle and distal duodenum that’s come from the proximal part of duodenum plays major role in net nutrient absorption Lamina muscularis mucosa is various in thickness in all parts of duodenum and was made up of smooth muscle fibres. Tunica submucosa in the duodenum of goose in this study consist of loose connective tissue rich with lymphoid fibres and duodenal glands. The musculosa layer consists of two smooth muscle layers outer longitudinal layer and a thick circular muscle layer that allow mixing and propulsion of the digesta through the intestinal trac

Structural and Electronic Properties of Theophylline- InP Diamantane Drug Carrier

Modeling   and simulation of nanostructure parameters of Theophylline bound with indium phosphide in diamantane structure have been performed with Gaussian 09 program. Density functional theory with hybrid B3LYP/3-21 basis sets was used to investigate the electronic and structural properties for Theophylline bound with InP diamantane nanocrystal as drug carrier. The optimized structures, total energies, energy gaps, highest occupied molecular orbital (HOMO), lowest unoccupied molecular  orbital (LUMO) energy, ionization potentials, electron affinities, chemical potential, global hardness, softness, and electrophilicity index have been investigated. Molecule has the smallest energy gap and the largest value of electrophilicity index in which this indicates that this molecule is more reactive than the others and has large chance to interact with the surrounding species in comparison with the other original Theophylline drug structure. A measure of molecular electrophilicity depends on both the chemical potential and the chemical hardness. The study suggests that the electrophilicity equalization principle is most likely to be a valid theoretical proposition, similar in nature to the electronegativity and hardness equalization principle. Indium Phosphide diamantane nanocrystal and its uses in drug-delivery are also discussed
