Cystic hydatid disease is a significant global health concern and a hazardous obstacle for public health and the livestock industry. The present investigation is aimed to determine the prevalence of hydatid cysts and economic losses in slaughtered animals (sheep, cattle, buffalo and camel) in Thi-Qar province, south of Iraq. This research was carried out from the beginning of February 2022 to the end of January 2023. The study focused on the prevalence of cystic echinococcosis in slaughtered animals from the central slaughterhouse of Nasiriyah city. The total cases (8847) were examined and the proportion of infection of hydatid cysts was: out of 2792 of examined sheep, 343 (12.29%) were infected, out 3209 of examined cattle, 288 (8.97.%) were infected, out of 1865 of examined buffalo 154 (8.26 %) were infected and out 980 of examined camels, 40 (4.08%) were infected. Among the infected animals in the Al-Nasiriyah abattoir, sheep recorded the highest prevalence, while camel abattoir recorded the lowest prevalence among other animals intermediate hosts. The incidence of hydatid cysts has a positive proportion to the age of animals. Regarding organ involvements, the liver and lungs were the most infected organs, the liver had a higher prevalence than the lung with infection rates of 62.3 % and 37.70% respectively. Females of sheep, cattle, buffalo, and camel were statistically higher than males, and were significant differences between the severity of infection and sex of hosts at (P≤ 0.05). Sheep was the highest fertility with 84.26%, this attributed to the sheep strains in this region have a higher morbidity rate compared to other regions.

It was noticed that the methanolic extract was more efficient in its effect on the bacterial species, as the rates of inhibition zones for this extract were (16, 18.66, 16.66, 19, 19.33 and 22.66) mm for each of P. aerogenosa, E. coli, Salmonella Sp., B. cereus., Staph. aureus and S. mutans, respectively.

This study was designed to determine the prevalence of autoimmune hypothyroidism (Hashimoto's) and its impact on men and women in Thi-Qar Governorat .The current study included (100) people who were in two groups, with (50) people in each group. The first group includes patients with hypothyroidism (Hashimoto's), and the second group includes (Healthy) people who do not suffer from any thyroid disease. Blood samples were collected for the period from (January 1 to March 30/ 2023), for use in measuring the level of thyroid hormones and measuring the level of autoantibodies.

The results of the current study showed that female patients had the highest incidence of autoimmune hypothyroidism (Hashimoto’s), at a rate of (68%), while for males, the incidence rate was (32%). As for the age group, the highest incidence rate was for ages over 40 years, and in both cases of the disease

The results also showed a relationship between (Sex, Family History, Smoking) and the risk of developing autoimmune hypothyroidism (Hashimoto’s). The results of the current study also showed an increase in the average concentration of thyroid-stimulating hormone (TSH) in patients with hypothyroidism (Hashimoto’s), corresponding to a decrease in the average concentration of each of the hormones (T3, T4, FT4) compared to the healthy group. An increase in the level of autoantibodies (Anti-TPOAb, Anti-TgAb) was also observed in patients compared to healthy people.

The present study was conducted in slaughterhouse of Al-Nassiriyah city at Thi-Qar province / Iraq to investigate the prevalence of Cysticercus tenuicollis (Taenia hydatigena cysts) in goats during the period from July 2022 to June 2023. A total 540 (286 male and 254 female) of goats were examined based on visual inspection method of meat. The current study showed that the prevalence of C. tenuicollis in the examined goats is 132(24.44%) and intensity of infection is 1.62. In this study, April recorded the highest infection rate (48.57%) with a significant difference (p < 0.05), followed by February (34.37%), while the lowest infection rate was in August (7.89%). Statistical analysis demonstrated there is no significant difference between the infection rate in the males (22.38%) and females (26.77%) goats, also, the intensity of the infection was relatively similar, 1.66 and 1.59 in the males and females respectively. The highest infection rate was recorded in older goats (29.24%) without significant variation (p > 0.05) when compared with young goats (17.57%). The most common site of C. tenuicollis was in omentum (84.85%) with a significant difference followed by liver (9.09%), while a low infection rate was recorded in other organs.

About five million people lose their lives every year to lung cancer, making it one of the leading causes of mortality worldwide. In the last few years, a lot of methods of detection of lung cancer were improved however these could not efficiently diagnose cancer. In this paper, a convolutional neural network (CNN) of robust deep learning is developed. CNN precision raises the deeper that is, however, it causes over-fitting or vanishing gradient problems simultaneously. To solve the issue, the CNN used resort to parallel CNN. It used Pictures the LIDC-IDRI consortium image collection has thoracic CT images that have been annotated for lung cancer diagnosis and screening purposes. The presented model includes result models of CNN which are integrated via ensemble methods and it compare with every model. Results of the simulation illustrate that the presented method's accuracy has developed by 2.18 percent in comparison with the method of the main paper

Various forms of boundedness in rectangular fuzzy n-normed linear spaces of type are examined in this work, where ∗ represents an arbitrary t-norm. Some of these highly general notions of boundedness have no counterpart in the traditional topological metrizable linear spaces. We list the properties of these bounded sets and conduct a comparative analysis of the various forms of boundedness. Among these are a number of ideas on the symmetrical characteristics of the objects under study that come from the classical context and are relevant to the issues of this magazine. We define their consequences and provide instances to show how different these notions are from one another.

This paper centers on an eco-epidemiological predator-prey model that accounts for hunting cooperation among predators and prey shelter and fear in afflicted prey. The objective is to investigate the effects of parameter factors on the model's bifurcation behavior. Theoretical part of this study demonstrate that a transcritical bifurcation can result from infection rate and refuge rate. Furthermore, fear rate can cause a Hopf-bifurcation to arise close to the positive equilibrium point. The presence of local bifurcations close to the non-trivial equilibrium points is verified by numerical analysis, which also guarantees the veracity of the theoretical results.Keywords:prey-predator, eco-epidemiological, fear effect, prey refuge,Bifurcation.1-IntroductionThe dynamic of eco-epidemiological models is one of the main themein mathematical biology, it considers the dynamics of infectious disease spreading among the ecosystem, notably prey-predator models with infectious diseases. Many studies shown that prey-predator relations have a significant impact on the way the ecosystems are organized, even though they considering predation as the alone source of interaction between the predator and its prey [1-4]. Recently in some theoretical and experimental studies prey individuals have been noted to alter their typical foraging behavior due the psychological strain of being
