In this research article, we have extracted simple closed form resolutions containing the variables and some parameters of the Lonngren wave equation and the (2 + 1)-dimensional stochastic Nizhnik-Novikov-Veselov system pressed in the Ito sense by augmentative noise. The acquired solutions of the Lonngren wave equation and the (2 + 1)-dimensional stochastic Nizhnik-Novikov-Veselov system may be effective to explore the electromagnetic signals in any cable lines and sound wave in any stochastic system respectively. For the required solutions, we use here the two variables (G1⁄G, 1/G)-expansion method and we notice the obtained solutions are ascertained in terms of trigonometric function, hyperbolic function, and rational function types. By taking the parameters as some special values, we see that the obtained solutions graphically imply the soliton solutions like as, singular solition, singular periodic solution, bell shape soliton and anti-bell shape soliton which all are added in the ultimate part of this paper.

Published: February 2023

This research work demonstrates an approach to solve nonlinear evolution equations via the generalized \(\left(G{\prime }/G\right)\)-expansion method which is an advantageous mathematical tool for establishing abundant solutions of these types of nonlinear evolution equations. Here, we select the \(\left(1+1\right)\)-dimensional integro-differential Ito equation and \(\left(2+1\right)\)-dimensional integro-differential Sawda-Kotera equation to extract the closed traveling wave solutions by using the mentioned method. In applied Mathematics, mathematical Physics, engineering science as well as real time application fields have enormous application of these type of equations. The new traveling wave solutions derived by this method are involving hyperbolic function, trigonometric function and rational function. This method is direct, efficient, convenient and powerful to solve other nonlinear evolution equations. Moreover, the features of the solutions are illustrated by some figures.

Authors: Shaffaf Noora N. , Ammash Haider K.
Published: February 2023

Shear behavior of two full scale honeycomb steel plate web girders that were modeled in finite element program was numerically studied. All girders were created with 0.30mm steel plate thickness and 20mm outside thickness of corrugated web. The girders were numerically loaded for an intermediate stiffeners to depth ratio (a/d) equal to 1%. The performance of plate web girder was improved through enhancement shear strength. The thin webs was strengthen by using corrugations system. Four cells of hexagonal honeycomb web were constructed to form the web cross section of such girder. One concentrated load was applied at mid span up to failure. The behavior of the shear girders was studied through reporting failure load values, shear buckling failure modes, maximum mid span deflections and load-displacement relationships. The numerical shear buckling strength of the girders were compared with theoretical value of the flat web girder. The finite element results showed that in general using honeycomb corrugated steel plate increased slightly the shear capacity of the girders compared with the flat web girder. Furthermore, the stability of honeycomb steel plate girder can be enhanced when more than one cell in honeycomb section was used which can increase the shear buckling strength regardless of the shear span to depth ratio.

Published: February 2023

Background
In Crohn's disease (CD), the inability to intubate the ileocecal valve during colonoscopy may be associated with a poor disease prognosis. In this study, we aimed to compare the long-term outcomes of CD patients with and without ileocecal valve intubation during colonoscopy to assess its value as a prognostic parameter.
Methods
This retrospective study involved CD patients with isolated ileal involvement who underwent colonoscopy between 1993 and 2022. We compared the basic characteristics and long-term clinical outcomes of two groups of patients: those with intubated and non-intubated ileocecal valves during colonoscopy.
Results
Of the 155 participants, 97 (62.5%) patients’ ileum could be intubated and 58 (37.5%) could not be intubated. The non-intubated group was older at diagnosis (39 years versus 30.5 years, p =0.002), but other baseline characteristics such as sex, smoking status, disease duration, perianal disease, and upper gastrointestinal involvements were similar. The non-intubated group had higher rates of steroid dependence (67.2% versus 46.4%; p =0.012), biologic treatment (89.7% versus 58.8%; p <0.001), CD-related hospitalization (81% versus 24.7%; p <0.001), and major abdominal surgery (58.6% versus 15.5%; p <0.001).
In the logistic regression analysis, the positive predictors of successful ileum intubation were inflammatory type CD (OR: 14.821), high serum albumin level (OR: 5.919), and older age (OR: 1.069), while the negative predictors were stenosing (OR: 0.262) and penetrating (OR: 0.247) CD behavior.
Conclusions
Crohn's disease patients with isolated ileal involvement, ileocecal valve cannot be intubated during colonoscopy may indicate the severity of the disease.
Conflict Resolution between Multi-Level Government and Farmers in Land Expropriation Based on Institutional Credibility Theory: Empirical Evidence from Shandong Province, China
Authors: Fan Shengyue , Luo Xijing , Han Peitao
Published: February 2023

The land expropriation policy of Merging Villages & Living Together (MVLT) in rural areas has intensified conflicts due to insufficient financial compensation and "demolishing old houses before building new ones". The current research rarely includes farmers, governments at all levels, the strength of policy tools, and policy perceptions into a unified quantitative research framework.This paper adopts the institutional credibility theory, incorporates the policy instruments of higher-level governments, administrative instruments of lower-level governments, and farmers' credibility of policies into a unified accounting framework, constructs a conflict stress index, evaluates the role of each subject's characteristics, policy perceptions, and policy instruments in the process of conflict generation and resolution, and analyzes the ways of conflict resolution from the perspective of different stakeholder games. The analysis framework are verified by using the case study of MVLT policy in Shandong Province, China.The results show that the credibility of the policy is influenced by individual characteristics and varies significantly. The administrative means and different combinations of the lower level government can significantly improve the success rate of policy implementation. The highest value of the conflict index was observed when the administrative instruments reached the maximum value without marginal increase in farmers' credibility for policy implementation and improvement were made.

Authors: zhang jinwei , qin long , ding shuzhen , hu xijian
Published: February 2023

Purpose: To explore the characteristics and risk factors of the joint incidence of Tuberculosis, Hepatitis B, and AIDS at the provincial level in China.
Methods: A Bayesian hierarchical spatio-temporal model of multiple diseases is established. The shared components are used to identify diseases with similar spatio-temporal patterns, and specific components explain the specific spatio-temporal patterns of each disease. Finally, the integrated nested Laplace approximation algorithm is used to estimate the posterior mean of each effect parameter.
Results: Tuberculosis and Hepatitis B have more similar shared space mode, and the shared space effect has the highest impact. The shared time risk of the three diseases has little change on the whole, and the change of specific time relative risk and combined time relative risk is quite different. Among them, the combined time relative risk of tuberculosis is almost constant, Hepatitis B first and then stabilizes, and AIDS shows a trend of increasing first and then decreasing.
Conclusion: The geographical environment factors may be used as a replacement for the shared Spatial effect. It has a more significant impact on the onset of Tuberculosis and Hepatitis B and has a negligible impact on the onset of HIV. In addition, some risk factors, such as economy and policy, may have different time effects on these three diseases.
Upstream water management and its role in estuary health, evaluation of freshwater management and subtropical estuary function
Authors: Julian Paul , Reidenbach Leah
Published: February 2023

In highly modified and managed systems the balance of freshwater inputs discharged to estuarine systems are important to maintain salinity balances and thus estuarine function. However, the availability of freshwater is highly dependent on upstream water management to provide flood protection whilst meeting freshwater demand for people and the environment. In South Florida, water is managed by a water control plan with Lake Okeechobee at the center. Currently, water levels within the lake are managed based on the Lake Okeechobee Regulation Schedule of 2008. The new regulation schedule, Lake Okeechobee System Operating Manual (LOSOM), updates water management rules while attempting to balance the needs of downstream systems; salinity and water quality in the Caloosahatchee and Saint Lucie (northern) estuaries; and more water for the southern Everglades. This study evaluates LOSOM relative to ecologically significant performance measures for the northern estuaries. Overall the proposed regulation schedule is expected to provide a more sustainable flow regime to the estuaries by reducing stressful and damaging discharge events. Moreover, new management rules combined with new infrastructure are expected to reduce low discharge events to the Caloosahatchee estuary and reduce stress on key indicator species such as Vallisneria americana during the wet season. This regulation schedule provides improved conditions for the estuaries, but Lake Okeechobee carries the burden. Future restoration and water management strategies are needed to maintain the benefits afforded to the estuaries while at the same time reducing the stress and damage to Lake Okeechobee to develop a more sustainable and resilient system.
Malus Species with Diverse Bloom Times Exhibit Variable Rates of Floral Development

Published: February 2023

In response to challenges caused by climate change, apple (Malus ×domestica) breeding programs must quickly develop more resilient cultivars. One strategy is to breed for various bloom times. Members of the genus Malus, including domesticated apple, wild species, and hybrids, exhibit striking variations in the bloom date. Although bloom time is strongly influenced by chilling requirements, other aspects of floral development in Malus and their contributions to bloom time are less known. The purpose of this study was to investigate potential connections between predormancy flower development and final bloom time in Malus species. We performed a phenological analysis of flower development in wild and domesticated apple with extreme differences in bloom time over the course of one developmental season. We tracked histological changes in the floral apex of representatives of three early-blooming Malus genotypes (M. ×domestica ‘Anna’ PI 280400, M. orthocarpa PI 589392, M. sylvestris PI 633824) and three late-blooming genotypes (M. angustifolia PI 589763, M. angustifolia PI 613880, M. ×domestica ‘Koningszuur’ PI 188517). Our study documented their floral meristem progression and organ development and expanded on current staging systems for apple flower development to describe the changes observed. The developmental trajectories of each genotype did not group according to bloom category, and we observed variations in the floral development stage at the time of dormancy onset.
Genesis of Mesozoic high-Mg dioritic rocks from the eastern North China Craton: Implications for the evolution of continental lithosphere
Authors: Guo Jun , Huang Xiao-Long , He Peng-Li , Chen Lin-Li , Zhong Jun-Wei
Published: February 2023

Pre-Cenozoic high-Mg andesites (HMAs) are mostly present in continental interiors, but their genetic relationship with continental lithosphere evolution remains unclear because of uncertainties of their mantle source, magmatic processes, and physicochemical conditions of formation. Early Cretaceous high-Mg dioritic rocks (HMDs, analogs of HMAs) of the Jinling complex in the Luxi area are typical intra-plate intrusions of the eastern North China Craton (NCC) and can be subdivided into two groups (Group-I and -II) on the basis of their petrographic and geochemical features. Group-I HMDs show low SiO2 contents (52.47–56.10 wt%) and Sr/Y (34.5–39.6) and (La/Yb)N (10.3–13.6) ratios but high contents of MgO (7.86–9.13 wt%), Y (18.3–20.3 ppm), Yb (1.43–1.47 ppm), and compatible elements (Cr = 407–585 ppm; Ni = 117–216 ppm), classifying as sanukitic rocks. Group-II HMDs are characterized by high SiO2 contents (63.81–64.87 wt%) and Sr/Y (47.1–63.4) and (La/Yb)N (16.1–17.5) ratios with low MgO (2.90–3.08 wt%), Y (0.88–1.04 ppm), Yb (0.88–1.04 ppm), and compatible elements (Cr = 201–213 ppm; Ni = 55–57 ppm) contents, belonging to adakitic rocks. Group-I and Group-II HMDs of the Jinling complex are closely related in spatial and temporal distribution, and all have enriched Sr-Nd isotopic compositions and arc-like trace element patterns with abundant hydrous minerals. Therefore, the Jinling HMDs should share a common source of ancient sub-continental lithospheric mantle that was metasomatized by aqueous fluids derived from the subducted Paleo-Pacific slab. The Jinling HMDs were not formed from interaction between slab-derived melts and mantle-wedge peridotites but were instead derived from partial melting of hydrous mantle peridotites in the continental interior of the eastern NCC. The distinctly different petrography, geochemistry, and mineralogy of the two groups of rocks resulted mainly from differing magmatic processes at crustal depths. Thus, Pre-Cenozoic intra-plate HMAs/HMDs are genetically distinct from Cenozoic HMAs that were mostly present in arc settings and generally represent juvenile crust growth. In a way, Archean tonalitic-trondhjemiticgranodioritic rocks (TTG) and sanukitoids, geochemically similar to HMAs/HMDs, could also be derived from interaction between slab-derived melts and mantle-wedge peridotites in arc settings or partial melting of hydrous mantle peridotites in continental interiors, and thus might not always be related with continental crustal growth and the onset of plate subduction.

Authors:   Institute of Natural Resources, Ecology and Cryology of the Siberian Branch of RAS, GUROVA Ol’ga Nikolaevna
Published: February 2023

Relevance. The relevance of the study is due to the fact that, despite the existing policy for equalizing the economic development and the efforts to improve the life quality of the population in the challenged eastern regions of Russia, the issue of economic and social disparity still stands. This is evidence that the approaches to the regions’ development and administration must be diversified and tailored to the specific needs of a given territory. The purpose of the article is to consider the basic conditions that form the opportunities and limitations of the regions’ development in connection with the availability of mineral resources. The informational basis of the study is derived from the official statistical indicators. Results. The article considers various indicators of the Russian Far East regions’ and the Baikal region’s basic development conditions. The aspect of the regions’ development due to the basic conditions in the context of the medical care availability is also highlighted. Conclusion. The lower basic development conditions indicators are observed in the following regions: Transbaikal Territory, The Republic of Buryatia and the Jewish Autonomous region. In these regions the situation with the per capita fiscal capacity and population’s the average monetary income by 2018 has worsened in comparison with the Russian average. The situation is somewhat better in Irkutsk and Amursk regions, but they are still on the second last place. The resource regions of the northern zone of the Russian East have higher levels of the indicators in question, that has to do with the presence of resources for the mining industry. A relevant issue for the eastern region in the field of healthcare is the issue of the human resources availability.

Research objective. This paper analyzes the foundation, existing problems and future development trend of Sino-Russian agricultural cooperation under the new situation. Research methods. Data analysis and comparative research were used in this paper. Research content. Russia has abundant land and poor labor resource but China has contrary situations. Which not only provides favorable conditions for agricultural trade, but also breeds huge potential for agricultural cooperation. As China and Russia continue to expand the opening of the agricultural product market, agricultural trade has gradually become a new bright spot in the economic and trade cooperation between the two countries. The development of agricultural cooperation between China and Russia has the advantages of obvious geographical advantages, strong complementarity of agricultural resources, and continuous improvement of cooperation policy planning. At the same time, there are practical difficulties such as low scale and level of agricultural cooperation and imperfect agricultural cooperation infrastructure. Conclusion. The agricultural cooperation between China and Russia is to optimize the allocation of resources and is in line with the common interests of the people of two countries. The agricultural cooperation between China and Russia shows the continuous improvement of cooperation policies and plans, the increasing variety of agricultural trade, and the continuous expansion of agricultural cooperation areas and regions. In the future, the two countries will strengthen communication between the government and the people at all levels, strengthen the construction of agricultural infrastructure, strengthen Sino-Russian cooperation in agricultural science and technology ,coordinate agricultural preferential policies and promote further agricultural cooperation between two countries

Authors:   Saint Petersburg Mining University, Canhimbue Ludmila Salete , Talovina Irina Vladimirovna ,   Saint Petersburg Mining University
Published: February 2023

Relevance. Since the 19th century, the Norilsk Ore district has been one of the world leaders in the production of platinum metals. Long-term research focused on the detection of sulfide platinum-copper-nickel ores contributed to the accumulation of a large volume of scientific material on the geology and ore content of the Norilsk region. Due to the emergence of new methods for ores studying, it seems necessary to analyze previously published data and assess the prospects for the joint application of traditional and modern methods in solving the problem of understanding the ore formation process. The purpose of the work – to summarize information about the geology of the Norilsk ore region and the platinum-metal mineralization associated with it, to note the main scientific achievements and identify promising areas for further research. Results. Thanks to comprehensive production and research geological works, differentiated basite-ultrabasite intrusions and ore-containing Paleozoic-Mesozoic sedimentary volcanic rocks of the Norilsk region have been studied at the highest level. The geological structures of the region and its metallogeny are also studied in detail. However, there is still no unambiguous understanding of the geodynamics of the magmatic process and, accordingly, the mechanism of formation of ore-bearing intrusions. Conclusions. In the conditions of depletion of known deposits, the decoding of the genesis of ores of the Norilsk region becomes particularly relevant. The use of modern computer X-ray microtomography in addition to geochemical and petrological studies makes it possible to analyze the three-dimensional distribution of platinum and sulfide minerals, to identify textural and structural evidence of processes that were previously questioned. The results of these studies may lead to a reassessment of established models of ore genesis, as well as an increase in the efficiency of ore processing.

Objectives: To know the distribution of IOL power among cataract patients attending tertiary care eye hospital. Materials and Methods: A hospital based prospective study was conducted on 2788 cataract patients attending tertiary care eye hospital from March 2022 to November 2022. All patients were subjected to detailed history taking and ocular examination. Age, gender, operating eye and power of IOL were noted. Results: A total number of 2788 cataract patients were recruited for this study. Out of 2788 patients, 1644 (59%) were females and 1144 (41%) were males. Majority of the patients were in the age group of 51-65yrs (54.9%) followed by 36-50yrs (22.2%) with female predominance. Among 2788 patients with cataracts the operating eye was right eye for 51.6% & Left eye for remaining ones. In all age groups commonest IOL power is in the range of 19 to 23D,the most common IOL Power in the age group 51-65yrs ,36-50yrs & 21-35yrs is 21.5D where as in 66-80yrs is 21D. The highest IOL Power notes of age groups 51-65yrs is 34.5D, 36-50yrs is 29D, 66-80yrs is 33D, 21-35yrs is 25D & <20yrs is 32D where as the lowest IOL Powers for the above age groups is 1D,3D,1D,10D & 16D respectively. The overall mean IOL power noted is 21.2D. The median IOL power noted in >80yrs is 22D higher than the other age groups which may be due to decreasing axial length and anterior chamber depth with increasing age. The required IOL power is higher in females (mean IOL Power 21.5D) than males (mean IOL power is 21D) which may be due to shorter axial length in females. No difference noted in IOL Powers between Right & left eye. Conclusion: Based on our study we conclude that the commonest age group presenting with Cataract is 51-65yrs with female preponderance. The commonest mean of IOL power noted is 21.2D. Females are requiring more IOL power than males which may be due to their shorter axial length and shallow AC depth. Highest mean IOL power among all is noted in age group >80yrs, which may be due to decreasing Axial length with increasing age. There is no difference noted in mean IOL power between Right & Left Eye. This study concludes that IOL power requirement varies with Age, Gender and Ethnicity. Calculation of IOL power should be done with utmost care to avoid post-operative refractive errors.

Objective: to compare the two immunological methods of HbA1c determination available at the two university hospital centers in the capital of Madagascar. Methods:Prospective comparative study between two HbA1C assay techniquesat the University Hospital Center Joseph RavoahangyAndrianavalona and University Hospital Center Joseph RasetaBefelatanana both localized at Antananarivo Madagascar was conducted. The two techniques used are immunoturbidimetry and immunofluorescence. Fifty samples were run simultaneously on both techniques to assess the dispersion and correlation of HbA1C values. A history of haemoglobin abnormalities is previously researched in the medical records for the samples. Results:The correlation coefficient for the 2 techniques is 0.97. The Bland â€“Altman plot shows a funnel-shaped appearance. The Interclass Correlation Coefficient is 0.851 CI [-0.036 - 0.962]. No hemoglobin abnormalities were documented in any of the 50 samples Conclusion: It is essential to keep the same technique for monitoring HbA1c. Our study shows poor reproducibility for the two techniques compared. A strong relationship between the technique used and the HbA1c value was found for the extreme values. It is important to specify the technique used to support prescribers.

Published: February 2023

In recent years, employer brand has been widely addressed as a crucial factor in attracting and retaining the best employees. Research on its impact on organizations can provide a better understanding of the benefits of employer branding in unlocking the potential of employees. Thus, this paper aims to evaluate the impact of employer brand on the relationship between psychological empowerment and employee engagement in Lithuanian companies. The study surveyed 429 employees (from < 18 years to > 65 years) of Lithuanian companies. The data were collected via an online survey of the respondents and by sending e-mails to the administrators of randomly selected Lithuanian companies requesting to share the survey link with their employees. Descriptive statistics, reliability assessment, ANOVA tests, multiple linear regression, and moderation analysis were used to analyze the collected data. The study found that employer brand directly impacts employee engagement (β = 0.114, p = 0.004). However, employer brand does not have a statistically significant effect on the relationship between psychological empowerment and employee engagement (p = 0.2224). Based on the results, employees working in Lithuanian companies are more engaged when they perceive their employer brand as positive. In contrast, when psychologically empowered, employees engage in work regardless of their perception of the employer brand.

A különböző társadalmi kontextusokból származó etnográfiai esettanulmányok, bár nem helyettesíthetik ezt a hiányt, exploratív jellegükkel hozzájárulhatnak a magyarországi romák kivándorlását vagy transznacionális, mobil munkavállalását jellemző tendenciák, motivációk és e migrációt működtető mechanizmusok megismeréséhez. Az esettanulmányok egy része azt mutatja, hogy a romák országhatárokon átlépő migrációja nem etnikai alapon szerveződik, hanem a társadalmi helyzetük szerint, valamint az ezzel összefüggő társadalmi kapcsolataik mentén. Az etnográfiai esettanulmányok nagy része, köztük az e tanulmány alapjául szolgáló kutatás is, az alacsony képzettségű romák mobil munkavállalási stratégiáit vizsgálva azt állítja, hogy a „feleslegesnek”, vagy „tartalék munkaseregnek” címkézett „szenvedő tömeg” (Bauman, 2003), köztük a tartósan munkanélküli kelet-európai romák népes hada, a „nehéz megélhetés” meg a „nagy fajgyűlölet” miatt, Magyarországon is elkezdett egy munkavállalási szempontból transznacionálisan mobil életet élni. Egy észak-magyarországi kistérségben végzett intenzív, több éves terepmunka eredményeként szerzett empirikus adatok alapján amellett érvelünk, hogy a migrációs kultúra az elmúlt két évtizedben már egyre több olyan települést érint, ahol korábban a romák szegregáltan éltek, még az országhatáron belül sem igazán mozogtak. Nincs okunk feltételezni, hogy ez a folyamat a közeljövőben megállna, vagy kisebb mértékű lenne, amennyiben a nyugat-európai munkaerőpiac szívóhatása, illetve a magyarországi körülmények változatlanok maradnak. A romák transznacionális vándorlása, amelynek időbeli dinamikája egyébként a többségi mintát követi, azonban sok tényezőtől függ: főként attól, meddig és mennyire marad nyitott az európai gazdaság és hogyan változnak az egyes célországok mobilitási rezsimjei.

Published: February 2023

Membrane filtration technology is widely applied in conventional surface water treatment plants because of its low power load and high filtration accuracy. This study follows the transition from a power-driven to a gravity-driven siphon-submerged ultrafiltration membrane system in a drinking water treatment plant in Shandong Province, China. The proportion of space membrane areas in the tank was further developed, by increasing the membrane areas of a single tank to 1.6 times that before the transformation, and the design production capacity of a single tank is increased from 10,000 m3/d before the transformation to 16,700 m3/d. The recovery rate of a single tank was also increased from 96.28 to 97.77%. The energy consumption per ton of water decreased from 0.06 to 0.017 MJ. The annual carbon emissions reduction reached 197.13 tons per tank. In terms of the water quality, the algae removal rate from surface water by the ultrafiltration membrane reached 100%. Further, the removal rates of 2 μm particles, turbidity, and chlorophyll were above 99%. Our results suggest that gravity-driven siphon-submerged ultrafiltration promotes environmental protection, energy conservation, and emissions reduction. This technology introduces a new development direction for membrane filtering in drinking water treatment plants.
Expression and Clinical Significance of PIEZO2 in Gastric Cancer
Authors: Liang Tong , Da Ming-Xu
Published: February 2023

Objective:

The aim of this research was to investigate the expression of PIEZO2 and its
potential clinical significance in gastric cancer (GC).

Methods:

In this study, we detected the protein expression levels of PIEZO2 in GC tissues and adjacent
normal tissues by immunohistochemistry (IHC) and analysed the relationship between the
protein expression levels of PIEZO2 and clinicopathological parameters of GC patients. Gene Expression
Profiling Interactive Analysis (GEPIA) and Kaplan–Meier Plotter were used to verify the
diagnostic and prognostic values of PIEZO2. Proteins interacting with PIEZO2 were predicted using
the SRING database.

Results:

Our results showed that the protein expression levels of PIEZO2 in GC tissues were lower
than those in adjacent normal tissues (all P < 0.05), and the protein expression level of PIEZO2
was correlated with lymph node metastasis and TNM stage of GC patients (all P < 0.05). Aberrant
overexpression of PIEZO2 was associated with poor prognosis of GC patients. Proteins such as
VR1, TRPV1, LHFPL5, STOM, TRPA1 and STOML3 had obvious interactions with PIEZO2 (P =
0.00213).

Conclusion:

In summary, our current study identified PIEZO2 as a promising target for early diagnosis
and as a potential prognostic biomarker in GC patients.

Association between FOXO3a Gene Polymorphism and Susceptibility to
Asthma in South Indian Population
Authors: Maheswarappa Mahendra , Basavaraju Manjula , Bhaktha Geetha , Anand Mahesh P. , Seetharama Nagabushan
Published: February 2023

Background:

Asthma is an important cause of morbidity worldwide. The FOXO3a gene plays an important role in human immune regulation and homeostasis. Loss of function may lead to chronic inflammation and asthma.

Objective:

To evaluate the association between Foxo3a gene polymorphism and susceptibility to asthma.

Methods:

We conducted a case-control study in a tertiary care hospital. Participants answered a questionnaire that collected demographic and clinical information. Asthma was confirmed by pre and post bronchodilator spirometry. Genotyping of the FOXO3a polymorphisms was performed us-ing PCR-RFLP.

Results:

The study population included 41 cases and 33 controls. Among cases, the heterozygous (CT) genotype frequency was greater compared to wild homozygous (CC) and mutant homozygous (TT) variants. In controls, the wild homozygous (CC) genotype frequency was greater compared to heterozygous and mutant homozygous variants. In the general model, the mutant homozygous (TT) group had significantly higher odds of 7.8 (1.78-34.07) of having asthma compared to the wild ho-mozygous (CC) group. The mutant homozygous (TT) group had greater severity of asthma as com-pared to the wild homozygous (CC) group. The mutant homozygous group (TT) had much lower lung functions, as compared to the wild homozygous (CC) group in asthmatics. Among non-asthmatic controls, lower lung functions were seen in the mutant (TT) group as compared to the wild (CC) group.

Conclusion:

We found a significant association between the Foxo3a gene polymorphism and asth-ma. The T allele, a variant of the Foxo3a gene polymorphism, is associated with a higher risk of asthma, and greater asthma severity. It is also associated with lower lung functions in both asthmat-ics and apparently healthy control subjects.
Evaluation of Dyspepsia with Optimal and Suboptimal Gastric Emptying
Tests in Patients with Euthyroid Goiter
Authors: Ceylan Sule , Yilmaz Necati
Published: February 2023

Objective:

The presence of gastroparesis in patients with dyspepsia can be evaluated by gastric
emptying scintigraphy. We aimed to evaluate gastroparesis with optimal solid gastric emptying
scintigraphy and suboptimal liquid gastric emptying scintigraphy in euthyroid goiter patients with dyspepsia.

Methods:

We included 67 patients diagnosed with euthyroid goiter with dyspepsia complaints. The
patients did not use any medication and did not have any other chronic diseases. Solid and liquid gastric
emptying scintigraphy was performed on all patients. In our retrospective study; the images were
reevaluated. The region of interest was plotted on the area compatible with the stomach and timeactivity
curves were obtained. The correlation of solid and liquid gastric emptying test results was evaluated.

Results:

Twelve (18%) of the patients were male and the mean age of the patients was 64 (49-75).
There is a correlation between solid and liquid gastric emptying scintigraphy (p< 0.0005, r: 0.0880).
Solid gastric emptying time was prolonged in 27 patients (40%). Liquid gastric emptying was prolonged
in 23 patients (34%). Solid gastric emptying was also prolonged in all patients with prolonged
liquid gastric emptying.

Conclusion:

According to the results of the optimal gastric emptying test performed with radio-labeled
solid food. The rate of gastroparesis was low in our patient group with dyspepsia complaints. However,
there is a correlation between the optimal test and suboptimal gastric emptying test results in our patient
group. Liquid gastric emptying scintigraphy may be preferred in specific patient groups in case of suspected
gastroparesis because of its easy application and short duration.

Background:

The diagnosis of uterine dysfunction (endometrial hyperplasia) is on the rise. The available
treatment is quite expensive and associated with some side effects. The therapeutic potential of natural products is now
being explored, as they are easily available with little or no side effects. Drymaraia cordata is folklorically utilized in
the treatment of diverse ailments including uterine fibroids

Objectives:

This study aims to investigate the potential therapeutic effect of chloroform fraction of methanol extract of
Drymaria cordata (CFDC) in estradiol benzoate (EB)-induced endometrial hyperplasia.

Methods:

Thirty-six rats were randomly divided equally into six groups. These included control group, CFDC: (100
mg/kg), CFDC: (200 mg/kg), EB: (2 mg/kg), EB + CFDC (100 mg/kg), and EB + CFDC (200 mg/kg). Endometrial hyperplasia
(EH) was induced by intraperitoneal injection of EB. The levels of estrogen (E2), progesterone (PG), Follicle
stimulating hormone (FSH), Luteinizing hormone (LH), Malondialdehyde (MDA), Superoxide dismutase (SOD), and
Glutathione peroxidase (GSH-Px) activities were determined using ELISA technique. The uterine histological assessment
and immunohistochemical expression levels of estrogen receptor, Ki-67, cytochrome c, and caspase 3 were carried out.

Results:

EH was severely expressed in the uterine section of EB-treated rats. However, CFDC administration improved
the pathological features of the animal model. The sex hormones levels were increased in the EB-treated group, which
were significantly reduced by CFDC. The antioxidant indices were also restored by CFDC. Immunoexpression levels
of ERα and Ki-67 were downregulated while cytochrome c and caspase 3 were upregulated by CFDC.

Conclusion:

This study suggests that CFDC contains phytochemicals that can protect against EB-induced EH via
modulation of hormonal signaling, apoptotic machinery, and oxidative indices.
