Published: February 2023

Background and Aim: Predicting high-risk patients is crucial in acute myocardial infarction (AMI). We aimed to investigate whether the leukoglycemic index (LGI) has a unique ability and to compare it with other inflammatory parameters in predicting in-hospital mortality in AMI.
Methods: In this single-center study, we retrospectively analyzed all AMI patients hospitalized and followed by a single operator. Patients were divided into two according to in-hospital outcomes. Other inflammatory parameters (systemic immune-inflammatory index, platelet-lymphocyte ratio, neutrophil-lymphocyte ratio, triglyceride-HDL ratio, and LDL-HDL ratio), C-reactive protein (CRP), and LGI were calculated according to previously described criteria. Univariable and multivariable logistic regression analyses were used to find independent predictors. The receiver operating characteristic (ROC) curve was used to find the cut-off point of LGI and other parameters in predicting mortality.
Results: A total of 304 patients with AMI were included in the study. The mean age was 62.18±11.89 and 74 (24.3%) of patients were female. The total death rate was 19 (6.3%). In univariate variable analysis, LGI was found as a significant predictor of mortality (p

MATERIALS AND METHODS: A case control study consist of three group included was in this study. The first group involves 50 patients with PC were observation in Al-Amal Oncology Hospital in the period from April 2021 to April 2022 under the supervision of oncology specialists was included in this study. Second group consist of 30 patients. They have benign hyper plaisa (BHP), this group has been collected from urosergical department . Third group was include 20 healthy volunteers (non prostate cancer and non BHP). Prostate specific antigen (PSA) was measured by mini – VIDAS device using kit supplied by Biomerieux – France. IL-10 and TNF-a levels were measured by ELISA technique using kit supplied by CAUSABIO – China. RESULTS: Results of the present study showed the 60–69 years age group scored highest percentage in benign (56.7%), malignant (54.0%), compared to control (healthy) (50.0%), while > 69 years scored least percentage in these groups (3.3%, 14.0%, and 25.0%) respectively with significant different (p< 0.05). Additionally, the IL-10 and PSA scored highest mean levels in the malignant group (1.22 ± 0.23 and 27.66 ± 6.31), while TNF-a scored highest mean levels in a benign group (0.30 ± 0.11). The least mean level of IL-10 was in healthy (0.42 ± 0.15), TNF-a in malignant (0.23 ± 0.03), and PSA in benign (6.73 ± 1.36). Finally, there is a significant difference among age groups and PSA, IL-10, and TNF-parameters. CONCLUSIONS: We concluded the PSA, TNF-a and IL-10 parameters are play important roles in pathogenesis patients with prostate cancer. PCa is high prevalence in elderly population.

Published: February 2023

Background: Neurodegenerative diseases (NDs) impose significant financial and healthcare burden on populations all over the world. The prevalence and incidence of NDs have been observed to increase dramatically with age. Hence, the number of reported cases is projected to increase in the future, as life spans continues to rise. Despite this, there is limited effective treatment against most NDs. Interferons (IFNs), a family of cytokines, have been suggested as a promising therapeutic target for NDs, particularly IFN- α, which governs various pathological pathways in different NDs. Objective: This systematic review aimed to critically appraise the currently available literature on the pathological role of IFN- α in neurodegeneration/NDs. Methods: Three databases, Scopus, PubMed, and Ovid Medline, were utilized for the literature search. Results: A total of 77 journal articles were selected for critical evaluation, based on the inclusion and exclusion criteria. The studies selected and elucidated in this current systematic review have showed that IFN- α may play a deleterious role in neurodegenerative diseases through its strong association with the inflammatory processes resulting in mainly neurocognitive impairments. IFN- α may be displaying its neurotoxic function via various mechanisms such as abnormal calcium mineralization, activation of STAT1-dependent mechanisms, and increased quinolinic acid production. Conclusion: The exact role IFN- α in these neurodegenerative diseases have yet to be determine due to a lack in more recent evidence, thereby creating a variability in the role of IFN- α. Future investigations should thus be conducted, so that the role played by IFN- α in neurodegenerative diseases could be delineated.
U.S.-Chinese Strategic Competition and the Ukraine War: Implications for Asian-Pacific Security
Authors: Winkler Stephanie 
Published: February 2023

Against the background of the intensified U.S.-Chinese strategic competition in recent years, this paper examines the implications of the Ukraine war for security in the Asia-Pacific. Based on a qualitative analysis of hundreds of governmental documents, speeches and news articles, the study finds that both the United States and China have exploited the Ukraine war to double down on their strategic rivalry in the Asia-Pacific. The Biden administration has cast China and Russia as similar threats to the international order; intertwined Europe’s problems with those of the Asia-Pacific; and pursued a global anti-authoritarian alliance directed against both Russia and China. China has become an increasingly uninhibited security-seeker as it has recognized its own rapidly deteriorating security situation; America’s resolve to maintain its China policy; and a unique strategic moment in which to present itself globally as an anti-hegemonic, responsible great power. Given these developments, the security situation in the Asia-Pacific is becoming ever more volatile.
Improving the geometrization reliability of qualitative indicators of phosphate ores during their open mining on the example of the Kovdorskoye apatite and staffelite ore field
Authors: Yanitskiy E. B. 
Published: February 2023

Background. In this paper, available methods for determining the geometry and density of exploration networks used in operational planning are discussed, along with approaches to determining the permissible error limits in the assessment of geological indicators. The Kovdorskoye apatite and staffelite ore field was selected as a research object.Aim. To determine the rational parameters of an in-mine sampling network for use in operational planning of phosphate ore mining.Materials and methods. The research was carried out as part of a project on the development of a methodology for operational in-mine sampling of apatite and staffelite ores. Quantitative data were processed and analyzed using the methods of mathematical statistics and cartography.Results. The conducted geometric autocorrelation and assessment of the anisotropy of variability in the content of components, which determine the quality of mineral raw materials, allowed the author to establish the rational parameters of an operational in-mine sampling network during the extraction of phosphate raw materials from the Kovdorskoye apatite and staffelite ore field.Conclusion. The absence of a pronounced anisotropy in the content of P2O5 and CO2 in apatite and staffelite ores was established, which implies the feasibility of using a uniform in-mine sampling network. The parameters of such a network were determined, which confirm the need to sample the rock cuttings in each borehole.
Pricing and Quality Setting Strategy in Maritime Transportation: Considering Empty Repositioning and Demand Uncertainty

Published: February 2023

<p> </p>
<p>Imbalanced international trade and the limited number of containers in the maritime transportation industry have resulted in considerable costs and decreased profits for shipping firms. To manage these issues, this study utilizes price management techniques to control empty container repositioning in a transportation system. In this system, there is a firm providing transportation services between two ports in both directions. </p>
<p>Each direction has its own uncertain potential demand that can be affected by the prices and the quality set by the firm. We develop a mathematical formulation to set the quality and prices of the service in order to maximize the firm’s profit. Due to demand uncertainty, we analyze different states of demand realization and discuss optimal policies for each state. These policies are then analyzed to develop a robust pricing and quality setting strategy under uncertainty. In addition, in order to easily implement the developed strategy, we propose an algorithm to convert the obtained results into a practical procedure that can be implemented by the shipping firm. Lastly, we investigate the impact of several factors on the firm’s profit and demonstrate that not only the firm’s profit but also the imposed regret depend on both internal and external factors such as the potential demands, price sensitivity, empty and loaded movement cost, and uncertainty control parameter.</p>

Published: February 2023

The Orchidaceae family stands out when it comes to the commercialization of pot flowers, this is due to their flowers being widely attractive and have variability of colors, size and shapes according to the species; this results in plants with high relevance to the economy in the floriculture sector. The goal of this study was to elucidate questions about the effect of micronutrients on initial growth, the influence of electrical conductivity and frequency of fertilizer application, and the efficiency of organic fertilization with castor bean cake, on the growth and nutrition of Brassia verrucosa Lindley orchid. Studies with mineral fertilization involving nitrogen (N), phosphorus (P) and potassium (K) in Cattleya and Phalaenopsis seedlings allowed to obserevar that the N increment increased the number of flowers in Cattleya, while P and K did not affect this variable. The salinity of irrigation water also has an effect on growth and flowering. The electrical conductivity, the sources of fertilizers, their interaction with the substrate, the balance between the nutrients, the quantities and frequencies to be used, in addition to the different phenological requirements and characteristics intrinsic to the species, are important aspects to be considered in fertirigation.

Published: February 2023

Vibrio alginolyticus LHF01 was engineered to efficiently produce poly-3-hydroxybutyrate (PHB) from starch in this study. Firstly, the ability of Vibrio alginolyticus LHF01 to directly accumulate PHB using soluble starch as the carbon source was explored, and the highest PHB titer of 2.06 g/L was obtained in 18 h shake flask cultivation. Then, with the analysis of genomic information of V. alginolyticus LHF01, the PHB synthesis operon and amylase genes were identified. Subsequently, the effects of overexpressing PHB synthesis operon and amylase on PHB production were studied. Especially, with the co-expression of PHB synthesis operon and amylase, the starch consumption rate was improved and the PHB titer was more than doubled. The addition of 20 g/L insoluble corn starch could be exhausted in 6-7 h cultivation, and the PHB titer was 4.32 g/L. To the best of our knowledge, V. alginolyticus was firstly engineered to produce PHB with the direct utilization of starch, and this stain can be considered as a novel host to produce PHB using starch as the raw material.
