A study on the determination of sex using lip print patterns among indigenes of Akwa Ibom State, Nigeria
No full textThe lip print pattern is the characteristic pattern of the wrinkles and grooves present on the labial mucosa. This study evaluated the determination of sex among indigenes of Akwa Ibom State, Nigeria using lip print patterns. 100 subjects (50 males and 50 females), aged 18-25 years participated in the study. With written consent, lip prints were collected from the subjects. Samples were analyzed using Suzuki and Tsuchihashi classification of lip prints. The lip samples were analyzed as a whole and then divided into six portions Right Upper Portions, Middle Upper Portion, Left Upper Portion, Right Lower Portion, Middle Lower Portion and Left Lower Portion and analyzed differently. Data were analyzed using the Chi-square test and T - test analysis. The result shows that the most prevalent lip print in males considering the lip as a whole is Type I (29%) while that of the females is Type I’ (32%). In six portions, there was a significant difference (p < 0.05) between the lip print patterns in male and female subjects in the Right Upper Portion (25.960), Left Upper Portion (15.455) and Middle Left Portion (19.948) suggesting that these portions can be effectively used for sex determination among these indigenes. There was no significant difference (p > 0.05) between the thickness of lip in males and in females but, the lower lip was significantly thicker (p < 0.01) than the upper lip in both gender. Results also showed that the length of lips in males was significantly longer (p < 0.01) than that of females. This study, therefore, concludes that determination of sex among indigenes of Akwa Ibom State using lip length and lip print patterns in specific portions of Right Upper Portion, Left Upper Portion and Middle Left Portion can be effectively done

Pitfalls in the hemostatic management of a liver transplantation
No full textLiver Transplantation is fraught with thrombo-hemorrhagic complications, due to the precarious hemostasis of the recipient, anhepatic conditions, and the release of hemostatic factors from the allograft. Disseminated intravascular coagulation and its “flat-line” variant are common causes of hemorrhage and thrombosis, and frequently force the clinician along with a delicate balance between hemorrhage and thrombosis. We present a case that highlights some of the more challenging diagnostic and management decisions in liver transplantation and presents a safe and carefully structured approach to hyperfibrinolysis in liver transplantation
Evaluation of the effect of titanium dioxide and gold nanoparticles surface treatment on the flexural strength of polymethyl methacrylate heat cure denture base resin
No full textAim: The purpose of this study was to evaluate the effect of Titanium dioxide and Gold nanoparticles surface treatment on the flexural strength of Polymethyl methacrylate (PMMA) Heat cure denture base resins.Materials and methods: A total of thirty PMMA Heat cure denture base resin test samples were fabricated of size 65 x 10 x 2.5 mm (rectangular shaped) according to ADA specification no.2. The samples were divided into three groups as Conventional PMMA heat cure denture base resin samples (GROUP I, n = 10 CONTROL), PMMA Heat cure denture base resin samples coated with Titanium dioxide nanoparticles (GROUP II, n = 10) and PMMA Heat cure denture base resin samples coated with Gold nanoparticles (GROUP III, n = 10). GROUP II and GROUP III PMMA Heat cure denture base resin test samples were coated by Magnetron sputtering. Flexural strength of GROUP I, GROUP II and Group III was evaluated by a three-point bend test using a Universal testing machine and the mean values were obtained.Results: The Mean flexural strength of GROUP I, GROUP II and GROUP III samples were 114.79 MPa, 142.48 MPa and 154.70 MPa respectively. On comparative evaluation of the flexural strength among the three groups GROUP III PMMA Heat cure denture base resin samples exhibited the highest flexural strength followed by GROUP II and least by GROUP I. The statistical analysis by ANOVA had shown that there is significance in flexural strength among the groups tested (p - value = 0.000*).Conclusion: Within the limitations of the study, PMMA heat cure denture base resin coated with Gold nanoparticles showed the highest flexural strength followed by PMMA Heat cure denture base resin coated with Titanium dioxide nanoparticles. Conventional PMMA Heat cure denture base resin without any surface treatment showed the least flexural strength

Applications of convolutional neural networks in chest X-ray analyses for the detection of COVID-19
No full textThroughout global efforts to defend against the spread of COVID-19 from late 2019 up until now, one of the most crucial factors that has helped combat the pandemic is the development of various screening methods to detect the presence of COVID-19 as conveniently and accurately as possible. One of such methods is the utilization of chest X-Rays (CXRs) to detect anomalies that are concurrent with a patient infected with COVID-19. While yielding results much faster than the traditional RT-PCR test, CXRs tend to be less accurate. Realizing this issue, in our research, we investigated the applications of computer vision in order to better detect COVID-19 from CXRs. Coupled with an extensive image database of CXRs of healthy patients, patients with non-COVID-19 induced pneumonia, and patients positive with COVID-19, convolutional neural networks (CNNs) prove to possess the ability to easily and accurately identify whether or not a patient is infected with COVID-19 in a matter of seconds. Borrowing and adjusting the architectures of three well-tested CNNs: VGG-16, ResNet50, and MobileNetV2, we performed transfer learning and trained three of our own models, then compared and contrasted their differing precisions, accuracies, and efficiencies in correctly labeling patients with and without COVID-19. In the end, all of our models were able to accurately categorize at least 94% of the CXRs, with some performing better than the others; these differences in performance were largely due to the contrasting architectures each of our models borrowed from the three respective CNNs
A new theory on the shape of the universe and the origin of the time
No full textIn this article, we have made a theoretical research, at the limit of the scientific reflection, to respond to the following query: what is the origin of the time? To find the response to this question, we adopted an attractive method. First, we have considered the light physical characteristics (speed, energy...) as the invariants. On this basis, we characterized all other physical systems by referring to the light. By this scheme, we showed that the calculation of the absolute physical characteristics of any system comes compulsory by the light viewpoint. That method avoids the use of mathematical transformations like Lorentz transformation; which is used in relativity to make invariant the equations by the change of the system of reference. Second, we made other hypothesis to find a law characterizing the interactions between matter and antimatter. Third, we used these interactions to quantify the time. The central query of this research led us to the shape of the universe and its volume. Finally, we found that the universe is a conical shape
Interface of polymers grafted on silica: Organization of the interfacial layer in presence and absence of solvent
No full textThe 1H NMR technique is used to study the behaviour of the poly (ethylene oxide) (PEO) chains grafted chemically on silica in the presence or not of solvent. A noticeable influence of the different physicochemical parameters on the conformation of the grafted macromolecules is evinced. Different models are proposed for different lengths of grafted polymer chains on the surface in the absence and presence of a solvent. Without solvent, the macromolecules lie very flat and the layer is more organized. In the presence of a solvent, the chains spread out and adopt a more extended conformation and the local concentration of monomers decreases
A two-phase sonographic study among women with infertility who first had normal sonographic findings
No full textIntroduction: Sonographic scan tests are real-time procedures but the female reproductive systems are subject to continued changes beyond the mid-menstrual period. Therefore a second test may be useful after mid-menstrual ultrasound tests among women with infertility who first had normal ultrasound tests during the mid-menstrual period. Aim: The aim of this study is to find out whether physiological changes beyond the mid-menstrual period in the female reproductive system could develop into findings that could be missed at the first ultrasound test among women with infertility during mid menstrual period. Method: One hundred and forty (140) women participated in this study, over a period of 12 months. The inter-observer correlations were carried out. The ultrasound test measured the diameters of the endometrium and ovarian follicle. The study was carried out during the mid-menstrual cycle when normal changes are optimal. The subjects were women of childbearing age (18 years - 40 years) with 28 days cycles who were referred from the fertility clinic. Women who had previous pelvic surgery, women on fertility therapy, and women who were unsure of the date were excluded from the study. Only women who met the inclusion criteria were selected for the study. The selection was by convenience sampling method. The women underwent the first phase of the ultrasound test during the mid-menstrual cycle. Those who had ultrasonographic-positive infertility reports were returned to the referral clinic. Only women who had normal ultrasonographic fertility reports were included in the second phase of further ultrasonographic tests. The scans were carried out further for four days for this second phase study and the result was again compared with normal values. (Endometrium Normal range 7.4 mm - 13.5 mm and ovarian follicles normal range 17.4 mm to 23.5 mm). Results: The first phase of the scan showed 108 (77%) of the women had positive infertility results for endometrium and ovarian follicles, while 32 (23%) of the women had a normal ultrasonographic result and were rescanned over days. The findings of the second phase scan showed that 10 subjects (7.30%) showed new abnormalities, Findings were distributed in three sub-groups in this second phase of the study. Sub-group A, 4 (2.67%) had enlarged unruptured follicles, sub-group B, 6 (4.30%) had an endometrial cavity filled with fluid, sub-group C, 22 (15.70%) subjects still had normal scans who may be referred for other studies. Conclusion: Women with infertility who had a normal scan at the mid-menstrual cycle should be followed up with a second-phase ultrasound scan before other tests
Ecology of vital activity as an element of antistress therapy on the example of the organization of the work of a medical center with industrial enterprises under the VMI program
No full textThe pandemic the new Coronavirus infection has brought changes in the health status of a large number of our citizens. The consequence of this has been a higher rate of employees seeking medical care and subsequent sick leave. Crisis phenomena in the economic and social life of society are associated with the consequences of the pandemic, moreover, the stress burden on the population increases with the consequences of the pandemic. All this affects the level of performance. The transferred COVID-19 has increased the number of patients with complaints of pain in joints and muscles, with the phenomena of cardiovascular pathology, as well as in breathing, increased frequency of asthma attacks, etc. That is, complications affected a wide range of diseases [1-4]. All this is the consequence, including neurological pathology, which is closely related to stress. According to surveys of several large industrial enterprises, 31.7% of those seeking medical help report anxiety, sleep problems, and a feeling of fatigue [5]. Exacerbation of chronic diseases was recorded in more than 50% of patients with COVID-19. The figures show that more than 1/3 of the population is chronically unwell, and more often than usual they apply for sick leave, which inevitably leads to a decrease in economic indicators [6-10]
