Objectives. Off pump beating heart technique for myocardial revascularization was used successfully both in low and high risk patients. Its application in low ejection fraction patients was limited. The aim of our study was to evaluate the results of this technique application in patients with low ejection fraction and to compare it with the on pump bypass technique. Methods. This retrospective study included 174 patients with ejection fraction below 0.45 who underwent isolated coronary artery bypass surgery. 37 patients underwent myocardial revascularization with the use of conventional coronary artery bypass grafting (cCABG), while 137 patients had off-pump beating heart bypass grafting (OPCAB). Different preoperative, operative and postoperative variables were evaluated in both groups. Results. The patients profiles and risk factors were similar in both groups. The mean EF for patients who underwent cCABG was 43 % (Q1 = 40; Q3 = 44) in comparison with 42 % (Q1 = 38; Q3 = 44) for the OPCAB patients - (U = 2105,5; Z = -1,6; p = 0,11). Predicted risk for surgery according to EuroSCORE was similar in both groups (U = 2004.0; Z = -1.97; p = 0.05). The number of grafts performed per patient was significantly bigger in the patients who underwent cCABG - 4.0 (Q1 = 3.0; Q3 = 4.0) Vs 3.0 (Q1 = 3.0; Q3 = 4.0) in OPCAB; (U = 1625.5; Z = -3.55; p < 0.001). Completeness of revascularization was similar in both groups (U = 2335.5; Z = -1.0; p = 0.316). Incidence of hospital mortality and complications were higher in cCABG in comparison with OPCAB. Incidence of inotropic support, ICU, hospital stay and blood transfusion was significantly bigger among patients who underwent cCABG. Conclusions. OPCAB technique can be used in myocardial revascularization in patients with left ventricular dysfunction. Morbidity and mortality was lower than that in the cCABG group.
Re-examination of Critical-angle Reflectometry Used in Ultrasonic Non-destructive Testing For Estimating Material Anisotropy
Authors: Liu Jia-Wei , Chang Young-Fo
Published: June 2022

Seismic critical-angle reflectometry (SCR) can hardly be regarded as a reliable standalone method for anisotropic parameter estimation of strata in seismic exploration, but ultrasound critical-angle reflectometry (UCR) is useful in ultrasonic non-destructive testing (NDT) and medical
ultrasound for the estimation of anisotropy in media. Therefore, there is a conflict between using critical-angle reflectometry (CR) in seismic exploration and applications of ultrasound. This study aims to find the reason as to why CR is useful in ultrasonic NDT and medical ultrasound but
unreliable in seismic exploration for anisotropy estimation of media. The results of the study show that the critical angle can be accurately determined from the maximum amplitude of the reflections for a plane wave as used in ultrasonic NDT and medical ultrasound and thus the anisotropy of
the medium can be successfully estimated by UCR. However, for the spherical waves used in seismic exploration, the maximum amplitude of the reflections is shifted towards post-critical offsets and the shift of the maximum amplitude relative to the critical point depends not only on the frequency
and model parameters but also the azimuth. Therefore, SCR cannot currently be regarded as a reliable standalone method for the anisotropic parameter estimation of strata.
Gender Roles, Social Problem-Solving and Attitudes Towards Sexual Aggression
Authors:   , Ozel Dicle , Nezu Arthur M.
Published: June 2022

Sexually aggressive acts, whether they are experienced or perpetrated, impact individuals functioning on both individual and societal levels. Sexual aggression is defined as the actions of a person engaging in sexual behavior with someone who does not or cannot consent to engage in that behavior. There are multiple pathways involved in the process of the expression of sexual aggression. Social problem-solving (SPS) as a cognitive and behavioral construct, as well as gender roles, constructs of pre-determined schemas, have both been independently shown to play a role in the expression of sexually aggressive behaviors (Nezu, Nezu, & D'Zurilla, 2013, Murnen, Wright, & Kaluzny, 2002). The purpose of this study was to investigate whether the differences in gender roles and social problem-solving, as well as the interaction effect between SPS and gender roles will influence attitudes and opinions toward sexual aggression. As such it was hypothesized that gender roles are significantly associated with attitudes on sexual aggression, and social problem-solving is significantly associated with attitudes on sexual aggression and lastly, gender roles and social problem-solving have an interactive effect on attitudes on sexual aggression with social problem-solving influencing attitudes on sexual aggression over and beyond gender roles. In this study, 250 individuals of all sexes were recruited to complete measures to assess gender roles (BSRI & MRNI:SF), social problem-solving (SPSI:R-S), and attitudes on sexual aggression (IRMA). The investigation involved Pearson's product-moment correlations as well as a hierarchical multiple regression in order to assess the relationship between the variables of interest. Partially supporting the hypotheses, total MRNI:SF, representing gender role ideologies, and total SPSI:R-S, representing social problem-solving ability, were significantly associated with IRMA, representing attitudes toward sexual aggression. However, the relationship was not in the hypothesized direction. The last hypothesis was partially supported as the regression model was significant but total SPS did not have an over and above effect on attitudes towards aggression. The data demonstrated non-normal distribution and results were interpreted with caution. In the event that the results of this study are replicated, future research should focus on revealing other possible influencers. Finally, if it is demonstrated that the hypotheses are supported in future research, Emotion Center-Problem-Solving Therapy could be a beneficial treatment for individuals showing accepting attitudes towards sexual aggression.

Background: Irrespective of the fact that the Niger Delta was known for its environmental pollution, neither organized environmental assessment nor human biomonitoring, including that of carbon monoxide (CO) had been performed in the region. The aim of the study therefore was to establish the severity of maternal impact on exposure to CO in the first trimester of pregnancy by quantifying the exhaled CO concentrations (ECOC) and to assess the effect of maternal age, body mass index (BMI) and parity on the severity of the impact.Methods: The study was of cross-sectional design carried out at the Rivers State University Teaching Hospital (RSUTH) in Rivers State. 490 consecutive pregnant women in the first trimester were recruited from the antenatal clinic from January 2021 to January 2022. Gestational age was estimated with the aid of ultrasound scan. Demographic, social and obstetric characteristics were taken. Exhaled carbon monoxide concentration (ECOC) was measured with the aid of a smokerlyzer. Data was analyzed, using the statistical package for social sciences (SPSS) version 25.0 (Armonk, NY) software. Ethical approval was obtained from the RSUTH ethics committee.Results: The mean value of ECOC 3.25±2.51 ppm was more than that obtained in other studies. Out of the total 490 patients that were assessed, 335 (68.37%) had mild impact from CO exposure (ECOC=1-3 ppm), 129 (26.33%) – moderate impact (ECOC=4-6 ppm) and 26 (5.31%) had severe impact (ECOC=more than 6 ppm). Moderate and severe impacts were more prominent in women of age groups 25-39 years and the differences in various age groups were statistically significant [X2=20.671, p<0.036, 95% CI (0.032, 0.040)]. Patients with higher BMI were more likely to have moderate and severe impact than those with lower BMI- 6 (33.33%) and 4 (22.22%) out of the 18 patients with class III obesity had moderate and severe impacts respectively. The differences in the impact at various BMI were statistically significant [X2=20.671, p<0.001, 95% CI (0.001, 0.002)]. There was inverse relationship between parity and the severity of the impact and the differences in various parity groups were statistically significant [X2=10.580, p<0.012, 95% CI (0.101, 0.113)]. There was also a paradoxical finding of 3 smokers having only mild impact.Conclusions: The mean value of ECOC 3.25±2.51 ppm was more than that obtained in other studies in non-pregnant women. Mild, moderate and severe impact from maternal CO exposure were established with the moderate and severe impact more prominent at maternal ages of 25-39 years, at higher BMI and at lower parity.

Authors: Zhang Zhipeng , Sun Weijia , Zeng Zhijun , Lu Yebin
Published: June 2022

Objective: This study aimed to identify novel prognostic biomarkers of pancreatic ductal adenocarcinoma (PDAC) using bioinformatics analyzes. Methods: Clinical information, microRNAs (miRNAs), and genes expression profile data from PDAC cases were downloaded from the Cancer Genome Atlas (TCGA) database. The potential prognostic risk miRNAs and genes were screened using the Elastic Net Cox proportional risk regression hazards (EN-COX) model. The receiver operating characteristic (ROC) curve and the Kaplan-Meier (KM) curve were used to identify miRNAs and genes of significant prognostic risk. Furthermore, significant prognostic risk miRNAs were functional enrichment analyses based on their target genes. Furthermore, the survival analyzes of the hub genes were validated through OncoLnc. Results: Complete clinical records and expression data of 797 miRNAs and 19969 genes from 137 PDAC cases were obtained, of which 59 potential prognostic risk factors, including 54 genes and 5 miRNAs, were selected by EN-COX analyzes. A total of 17 significant prognostic risk markers were identified (all P<0.05), including 16 genes and 1 miRNA (miRNA-125a). The miRNA-125a target genes were found in the MiRWalk database and the function enrichment analyzes were performed in the the DAVID website. Furthermore, according to data from the Oncomine and Human Protein Atlas (HPA) databases, the mRNA and protein level of frizzled class receptor 8 (FZD8) were overexpressed in pancreatic cancer tissues compared to the corresponding noncancer normal tissues (P<0.001). However, both glutathione S-transferase mu 4 (GSTM4) and inducible T cell costimulator ligand (ICOSLG) were negatively regulated in tissues of pancreatic cancer tissues (P<0.001). Finally, survival analysis was used to validate these factors by the OncoLnc database, and the results revealed that overexpression of ICOSLG was associated with a better prognosis (P=0.025). Conclusions: This study showed that the expression levels of FZD8, GSTM4 and ICOSLG were significantly different between PDAC and non-tumor tissues, especially ICOSLG, which could be a prognostic indicator and therapeutic target for PDAC.

Бухгалтерский учет является областью задания, который необходим для всех, кто участвует в предпринимательской деятельности. Менеджер несет ответственность за достижение целей, поставленных руководством или учредителями компании. Эффективность руководителя во многом зависит от информации, которую он использует для планирования, контроля и регулирования управленческой деятельности, а также для принятия решений. Формирование управленческого учета было основано на учете затрат, и поэтому его основным содержанием является учет производственных затрат будущих и прошлых периодов по различным аспектам классификации. Эта проблема не утратила своей актуальности и сегодня, поскольку себестоимость продукции, прибыль организации и, соответственно, налог на прибыль рассчитываются исходя из себестоимости предприятия. Таким образом, выбор метода расчета себестоимости продукции напрямую влияет на финансовый результат предприятия.
Plant Growth Promoting Microbes in the Future Management of Indonesian Estate Forests
Authors: Gafur Abdul
Published: June 2022

Plant growth promoting microbes (PGPM) are soil-borne microbes that colonize plant internal tissues as endophytes or live on root surfaces. They are classified into three main groups based on their growth promoting mechanisms, namely biofertilizers, biostimulants, and biocontrol agents, each of which contribute directly or indirectly to improved plant growth and productivity in a variety of ecosystems. PGPM development as biocontrol agents in the context of integrated pest and disease management has been a research program initiative in several forestry companies for quite some time. Adoption of PGPM as biofertilizers and/or biostimulants, particularly in nursery operations to produce vigorous and healthy seedlings, has recently gained traction. The current state and potential future roles of PGPM in the sustainable production of Indonesian estate forests are discussed in this paper.

The focus of this research was to determine the growth and yield of several melon lines in generation S3, as well as to estimate the genetic variants, morphologies, and yield heritability. A randomized design was used, which consisted of a single factor with four replications. Six melon lines from generation S3 were used, namely DS-1-1-4, DS-1-1-10, DS-1-1-11, DS-1-2-10, DS-1-2-17, and DS-1-3-3, for a total of 24 experimental units. There were ten plants in each experimental unit. The smart farming hydroponic system was used. Plant height, stem diameter, male and female flowering, horizontal and vertical fruit girth, pulp thickness, fruit weight, and total soluble solids were the parameters measured. The data were analyzed using analysis of variance and the genetic parameter was estimated by analyzing the genetic coefficient of variation and broad sense heritability. Except for plant height, the results showed that all of the characteristics had a low genetic coefficient of variation. Plant height two weeks after planting showed high broad sense heritability (84.56%), as did pulp thickness (77.89%), female flowering (75.83%), male flowering (74.65%), plant height three weeks after planting (66.25%), and plant weight (50.81%). Plant height, male and female flowering, vertical fruit girth, and fruit weight were best represented by the DS-1-2-10 lines.

In crop production, phosphorus (P) is the second most important limiting nutrient. However, due to precipitation reactions with Al3+, Fe3+ in acidic soil, or Ca2+ in alkaline soil, its availability in soil is severely limited. Microbes have recently been proposed as a means of increasing the bioavailability of soil phosphate for plants. The goal of this research was to isolate and identify phosphate solubilizing molds (PSM) from various plant rhizospheres, including gadung (Dioscorea hispida Dennst), maize (Zea mays L.), bamboo (Dendrocalamus asper), pineapple (Ananas comosus L.), and banana (Ananas indica L.). PSM was isolated in vitro and then diluted using the dilution plate technique with Pikovskaya’s solid medium. Five colonies were confirmed as PSM, namely Talaromyces aculeatus, Metarhizium anisopliae, Fusarium proliferatum, Mucor hiemalis, and Aspergillus niger, out of fourteen colonies formed from those rhizospheres. In the PVK solid medium, these isolates were capable of solubilizing insoluble P with a solubility range of 2.05 to 3.03. Talaromyces aculeatus (125.6 mg L-1), Metarhizium anisopliae (80.76 mg L-1) and Fusarium proliferatum (41.59 mg L-1) were the best P solubilizers, followed by Mucor hiemalis (9.51 mg L-1), and Aspergillus niger (7.85 mg L-1), respectively. The bioinoculants Talaromyces aculeatus and Metarhizium anisopliae had the most potential.

Clove plants are routinely fertilized with synthetic fertilizer to increase yield. The use of synthetic fertilizer reduces soil productivity. Biofertilizer can be used as an alternative for increasing soil fertility. The goal of this study was to determine the potency of bacteria isolates capable of producing indole acetic acid (IAA) hormone and solubilizing phosphate, and to identify bacteria species from the rhizosphere of clove plants. Soil samples were collected from the clove plants’ rhizosphere, environmental parameters were measured, the potency of IAA-producing and phosphate-solubilizing bacteria was analyzed, and bacteria were molecularly identified. After 48 hours of incubation, isolate TCKI 5 from Karangasem produced the highest IAA hormone levels (19.64 ppm), and isolate TCBP 6 from Buleleng had the highest index of solubilizing phosphate (1.91). A compatibility test between the three best isolates of IAA hormone-producing and phosphate-solubilizing bacteria revealed that TCKI 5 was able to associate with TCBP 6. Isolate TCKI 5 was identified as Leclercia adecarboxylata C107 with a 99.92% similarity, and isolate TCBP 6 as Burkholderia cepacia GJ8 with a 99.61% similarity.

Isolation, Screening, and Characterization of Methane-Utilizing Bacteria From the Sediment of Lowland Rice
Authors: Pratiwi Etty , Akhdiya Alina , Satwika Taruna D.
Published: June 2022

Methane is a major greenhouse gas that contributes to climate change. Methanogen and methanotrophic group microbes play a role in methane emissions in lowland rice fields. Methane is produced by methanogenic bacteria that decompose organic matter in anaerobic conditions. These bacteria will be active if the soil is inundated for an extended period of time. Some of this methane will be oxidized by methanotrophic bacteria in the rhizosphere. The researchers aimed to isolate, screen, and characterize methane-utilizing bacteria in lowland rice sediment from several Indonesian provinces. 27 methane- utilizing bacteria were isolated from rice field sediments in Lampung, West Java, and East Nusa Tenggara Province. Six of them had the potential to reduce methane emissions by more than half. A pmoA-like gene could be found in all of the selected isolates. The bacterial isolates were identified as Mycobacterium senegalense, Bacillus marisflavi, Bacillus methylotrophicus, Flavobacterium tirrenicum, Providencia stuartii, and Rhizobium rhizoryzae after characterization and identification with the Biolog OmniLog® ID system. These were all capable of nitrogen fixation, phosphorus solubilization, and IAA production. These isolates have the potential to be used as biofertilizers and methane mitigation agents.

Authors: Hendarjanti Henny , Sukorini Henik
Published: June 2022

Biological agents are critical in the management of major diseases in oil palm plantations. The potential of arbuscular mycorrhiza fungi (AMF) and Trichoderma spp. to control basal stem rot disease was investigated in this study. Three-month-old seedlings treated with AMF since the beginning of planting demonstrated AMF colonization of the roots. With a 25 gram AMF treatment in the main nursery, AMF colonization increased by 85.99% in TBM-1 (the 1-year immature plant). In TBM-2, AMF colonization increased by 86.00-97.33% (2-year immature plant). All of the treatments started with 30 grams of Trichoderma spp. applied at the start of pre-nursery planting. Root colonization and the number of spores in the root rhizosphere in TBM-2 had a strong relationship (2-year immature plant). AMF inoculation had a significant impact on root colonization and spore number response. According to this study, the application of 25 grams of AMF in the pre-nursery and main nursery, as well as repeated additions at planting, were found to be effective in controlling attacks of basal stem rot disease through early prevention strategies.

Published: June 2022

The quality of strawberry seedlings is impacted by the composition of the growing medium. Due to its good drainage and high water-holding capacity, coco-peat is now widely used as a major component of strawberry substrate; however, coco-peat has a low nutrient content. By combining coco-peat with manure and biofertilizer, more nutrients can be provided. This study investigated the effect of the growing medium composition with biofertilizer inoculation on the growth and quality of strawberry seedlings in a mountainous area using a pot experiment. With six treatments and five replications, the experiment was set up in randomized block design. The treatments involved substrate composition, which included cocopeat and chicken manure in ratios of 2:1, 2:3 and 3:2, and biofertilizer inoculation (with and without). Nitrogen-fixing bacteria and phosphate-solubilizing microbes were included in the biofertilizer. The results showed that substrate composition affected plant height, shoot and root dry weight, chlorophyll content, and nitrogen and phosphorus uptake by seedling shoots, but not the surface area of leaves on six-week-old seedlings. The addition of biofertilizer to substrates made up of cocopeat and chicken manure in ratios of 2:3 and 3:2 increased plant growth and nitrogen and phosphorus uptake.

In the esterification-transesterification method, a catalyst increases the reaction rate to produce biofuel (biodiesel). This study investigated the use of a solid catalyst consisting of green nano-CaO as a support modified by KOH solution and sulfated TiO2 for converting waste frying oil (WFO) into biodiesel in a single-step esterification-transesterification reaction. With nano-CaO prepared from eggshell, a green nanocomposite of CaO/K-sulfated TiO2 was synthesized by physical mixing and the hydrothermal method. Crystallite size, surface basicity-acidity, functional groups, and surface morphology were used to characterize the solid catalyst, which was then tested for its ability to convert WFO into biodiesel. The results showed that green-CaO had nanoparticles (93.13 nm) and that its size decreased after being modified with KOH (46.43 nm) and sulfated TiO2 (62.10 nm), with CaO/K-sulfated TiO2 being the optimum surface acidity-basicity. The optimum conditions for conversion were found to be 5% catalyst concentration to oil, a molar ratio of methanol/oil of 9:1, and a reaction time of 60 minutes, which resulted in a biodiesel mass yield of 94.17% higher than CaO/K (67.88%). WFO was successfully converted into fatty acid methyl esters, according to the GC-MS analysis of the biodiesel. The synthesized solid catalyst has the potential to be used in single-step esterification-transesterification reactions to produce biodiesel.

Authors: Sopialena Sopialena , Mirza Alexander , Nggudu Maria Fatima
Published: June 2022

Soil conditions in coal mining areas are generally poor in terms of nutrient availability, necessitating the addition of nutrients as well as microbial investment to improve aeration and increase nutrient availability for plants. This study examined the ability of the fungi Metarhizium sp. and Trichoderma sp. to increase tomato plant growth and yield, as well as the ability of these fungi to increase soil fertility in post-coal mining soil. The data were compiled using a completely randomized design with four replications, and the study used post-coal mining soil. Metarhizium sp. and Trichoderma sp. were used, with doses of 0 g, 3 g, and 5 g in each treatment. Plant height, number of branches, number of flowers, and fruit production were all evaluated as growth parameters. The data were analyzed using variance with a level of 5% using the least significant difference test. Increases were found in soil pH, C-organic, nitrogen, phosphorus, and potassium, resulting in an increase in soil fertility. Adding Metharizium sp. and Trichoderma sp. increased soil fertility, tomato plant growth, and production.

Published: June 2022

Mycorrhizae and organic fertilizers play a critical role in nutrient availability and absorption, soil texture development, and hormone production to promote plant growth. The aim of this research was to determine the influence of planting density on intercropping maize and mycorrhizal soybeans, and the impact of organic fertilizers on maize and soybean yields in dry lands in North Lombok. The experiment was conducted using a randomized block design with five intercropping treatments: P1 = 2 maize lines: 2 soybean lines, P2 = 3 maize lines: 2 soybean lines, P3 = 3 maize lines: 3 soybean lines, P4 = 4 maize lines: 2 soybean lines, and P5 = 4 maize lines: 3 soybean lines. The data were then analyzed using two-way ANOVA and Tukey’s significant difference test with a significance level of 5%. It was found that the P3 density showed the highest yield compared with the other intercropping treatments; the number of spores and mycorrhizal infection rate were also increased. The P3 treatment, with the addition of 15 tons of cow manure per hectare and inoculation with AMF, enhanced the yield and promoted the development of mycorrhiza.

Published: June 2022

The COVID-19 pandemic continues to be a global issue that draws worldwide attention. Countries are racing to develop vaccines and drugs to combat the COVID-19 virus. Immunomodulators are used in some of the prevention efforts. Any drug or substance that affects the immune system is classified as an immunomodulator. Bovine colostrum is an example of an immunomodulator. Colostrum is the mammary gland’s first secretion after birth, and it differs from mature milk in that it contains more proteins, immunoglobulin-A, vitamins, minerals, bactericides (lactoferrin, lysozyme, and lactoperoxidase), and growth factors. This review examines immunomodulators across various perspectives and characteristics, as an alternative for increasing the body’s resistance, and possible mechanisms are discussed. This review thereby facilitates the choice of suitable immune enhancement for the prevention and treatment of COVID-19.

The paper deals with the issues of increasing the depth and diameter of the cavity in various obstacles under the action of shaped charges covered with copper and tungsten as bimetallic, two-layer combined linings. Barriers made of soft iron and steel of different hardness and strength, as well as combined steel - duralumin and water - steel barriers, simulating various conditions for the penetrating action of shaped charges, are used as breakable barriers. The work is experimental in nature. The results of experimental studies are presented in the form of graphical dependencies, diagrams and X-ray patterns of the formation of a cumulative jet from combined linings. The study comparatively evaluates the action of shaped charges with shaped-charge linings of various designs, including the original single-layer copper lining. The evaluation depends on the method of forming a tungsten layer on the inner surface of the lining and its thickness. The study gives recommendations on the use of shaped charges with combined copper-tungsten shaped linings when acting against various obstacles.

Published: June 2022

The paper centers on the problems of developing failure- and fault-tolerant systems for Earth remote sensing satellite constellation control. The study defines the concept of a complex that fail-safely performs a target task, in this case, the task of detecting a target event and monitoring its behavior and development, i.e. monitoring the target event, and gives a hierarchical satellite constellation structure. Findings of the research show that it is necessary to use dynamic redundancy, which can significantly increase the trajectory of self-controlled degradation and, accordingly, the satellite constellation active life. The complexity of the problem lies in ensuring the reliability of the results obtained when a large number of target events, both natural and man-caused, occur. The study introduces an approach to reduce hardware redundancy, i.e. monitor a larger number of events using a lower power satellite constellation, and proves that is possible to use the approach without losing the system reliability.

O processo de urbanização acelerado e desordenado aliado ao rápido crescimento populacional pode contribuir para mudanças microclimáticas nos espaços urbanos. Em regiões de clima tropical, o adensamento excessivo da cidade e a supressão da vegetação podem induzir a formação de ilhas de calor urbanas e criar situações de desconforto térmico. O conhecimento das variáveis de conforto térmico, desenho urbano e interações entre os espaços construídos e naturais é fundamental para a modelagem e alteração desses espaços para torná-los mais agradáveis. Este trabalho tem como objetivo analisar a influência da forma urbana sobre o microclima nos bairros de Copacabana, Ipanema e Ramos, na cidade do Rio de Janeiro, Brasil. Para tanto, foram analisados os resultados de simulações microclimáticas, realizadas com ENVI-met. Além disso, os dados computacionais ainda foram utilizados como insumos para o cálculo do índice de conforto Physiological Equivalent Temperature (PET). Os resultados indicaram que o desenho urbano pode influenciar no microclima local.

Background: Hypodontia of lateral incisors (LI) is frequently associated with other dental anomalies. The objective of this study was to determine the association of LI with other dental anomalies by comparing the two groups: Group 1 with hypodontia of the maxillary LI (MLI1) and Group 2 with hypodontia of the mandibular LI (MLI2), in secondary school education students in Kosovo. Methods and Results: A total of 3306 secondary school students aged 12-16 years, regardless of gender, were included in this prospective study. The abnormalities investigated were recorded by RTG-panoramic and dental charts. The teeth were recorded as a congenital absence when the mineralization of the crown, identified by panoramic tomography, was absent. The prevalence of LI hypodontia was as follows: MLI1 (Group 1) included 36 cases (92.3%) and MLI2 (Group 2) included only 3 cases (7.6%), which indicates a much higher percentage of cases with hypodontia of MLI1. In Group 1, 21(58.3%) cases of LI hypodontia were bilateral and 15(41.7%) unilateral; in Group 2, 2(66.7%) cases were unilateral and 1(33.3%) case – bilateral. Among dental anomalies, the occurrence of rotation was found in 19(48.7%) cases with LI hypodontia: 47.2% cases in Group 1 and 66.7% cases in Group 2. The prevalence of dental inclination anomaly was 30.77% of all cases with hypodontia of LI: 27.8% of cases in Group 1 and 66.7% of cases in Group 2. The prevalence of ectopy was in 17.9% of cases of all hypodontia cases of LI: 16.7% of cases in Group 1 and 33.3% of cases in Group 2. Crown anomalies were evident in 7(17.9%) patients of all hypodontia cases of LI, all of which were in Group 1. Other anomalies such as microdontia were evident in two patients in Group 1. Transposition, bodily movement, and superposition were present in one patient in Group 1; in Group 2, one patient had transposition. At the same time, the frequency of dental transposition was significantly higher in Group 2 than in Group 1 (P=0.02088). Other dental anomalies of crown and root and infraposition were not present in both groups. There were no significant differences in the other dental anomalies between the two groups. Conclusion: The consequences of hypodontia in dental arches are obvious. Knowing the prevalence of hypodontia and its association with other dental anomalies helps classify the need for further treatment for the patients, whether orthodontic, prosthetic, or surgical.

The purpose of this study was to evaluate the anticoagulant activity of Thymus atlanticus leaves. Methods and Results: This cross-sectional study was carried out in Khartoum state from March 2021 to June 2021. This study comprised 60 healthy volunteers (40% men and 60% women) aged 19-25 years. Activated partial thromboplastin time (APTT) and prothrombin time (PT) were evaluated in the blood plasma with different amounts of Thymus atlanticus leaves using Coatron M1 (TECO Medical Devices). Thymus atlanticus leaves considerably lengthened APTT and PT in all tested concentrations. Furthermore, only the APTT test at a concentration of 5.17 μl revealed a significant difference in the anticoagulant activity of Thymus atlanticus leaves between males and females. No correlation between age and anticoagulant activity of Thymus atlanticus leaves on PT and APTT in the study was found.

Published: June 2022

Background: Gold mining is the world's leading source of anthropogenic mercury pollution, negatively impacting not only miners but also the surrounding inhabitants; it has many effects on human health, especially cardiovascular problems, which lead to coagulation disorders and an increase in morbidity and mortality rate. The present study aimed to determine the prothrombin time (PT) and partial thromboplastin time (PTT) among Sudanese gold mining workers exposed to mercury. Methods and Results: This cross-sectional study was carried out among mining workers in the Red Sea state. A total of 50 mining workers were enrolled in the case group, and 50 non-mining apparently healthy subjects were the control group. About 5 ml of whole blood samples were collected in 3.2% sodium citrate blood collection tubes. Platelet poor plasma (PPP) for prothrombin time (PT) and partial thromboplastin time (PTT) measurements was obtained by using high-speed centrifugation. PT and PTT tests were performed using a standard method (Practical-Haemostasis.com.) with a Helena C2 coagulometer (Germany) and reagents manufactured by the Bio-med trademark (China). The mean age of miners was 33.5±11.5 years and occupation time - 1.94±2.1 years. The mean value of PTT was greater in the case group than in the control group (42.43±6.18 sec vs. 37.76±5.33 sec, P=0.000). In the age subgroup <40 years, the PT level was longer than in the age subgroup >40 years: 14.04±1.38 sec vs. 13.15±1.35 sec (P=0.045), respectively. The correlation analysis revealed a significant, direct correlation between PTT and occupation time (r=0.357, P=0.011). Conclusion: Prolonged coagulation time, notably PTT, has been revealed among mining workers, implying that these workers may have a clinically silent state of coagulation abnormalities.
