The use of medicinal plants for the treatment of diseases, including cancer, is acknowledged and accepted in many African nations. Heavy metal contamination of plant materials poses a potential health risk, particularly for populations that are already vulnerable. This study determine the levels of heavy metals in medicinal plant samples used for treatment of skin cancer and evaluate the health risk caused by heavy metals to the adult population in Pretoria, South Africa using inductively coupled plasma mass spectrometry (ICP-MS). The concentrations of metals were as follows; As (< 0.2–1.04 ± 0.026), Cd (0.02 ± 0.00026–0.167 ± 0.006), Pb (0.38 ± 0.01–2.27 ± 0.05), Cr (5.31 ± 0.21– 26.9 ± 3.96) mg/kg and Hg which were lesser than 0.02 mg/kg. The mean concentrations of all analyzed heavy metals are above permissible limit except for Hg which are lower than the permissible limit. The Hazard Quotient (THQ) was less than 1 for all the heavy metals, suggesting that there is no obvious non-carcinogenic health risks associated with the consumption of these medicinal plants for now even though the prolonged use may result in health risks. The ingestion route was identified as the primary contributor to the overall risk by the health index (HI) values in the present study were more than 1, indicating that the combined effects of the heavy metal contaminants present in a particular herbal preparation pose health risk in the long term. Our findings support the need for close monitoring of potential heavy metals concentrations in medicinal plants given to patients from herbal shops.
Constructing invariants of Weil representations associated with finite quadratic modules of square-free level
Authors: Xiong Ran
Published: April 2023

Constructing invariants of Weil representations associated with finite quadratic modules is basic and important in the topic of modular forms. In this article we construct a family of invariants of Weil representations associated with square-free level quadratic modules by computing the shadow of nonholomorphic Eisenstein series of vector-valued modular forms of weight two explicitly. Furthermore we prove that, for any finite quadratic module whose cardinality is a square of an odd prime p-power and the 𝔽p-dimension is more than five, the space of invariants of Weil representation associated with this finite quadratic module must contain nonzero elements.

Authors: Demircan Turan , Yavuz Mervenur , Bölük Aydın
Published: April 2023

Lung cancer is a highly aggressive malignancy with limited therapeutic options and a poor prognosis. Due to the development of resistance to chemotherapeutic drugs, novel therapeutic agents are required. Androgen receptor (AR) signaling affects various genes contributing to cancer characteristics, including cell cycle progression, proliferation, angiogenesis, and metastasis. The misregulation of AR signaling has been observed in many cancers, including lung cancer. Therefore, inhibiting AR signaling using anti-androgens, AR inhibitors, or AR-degrading molecules is a promising strategy for treating lung cancer. Selective androgen receptor modulators (SARMs) are small molecule drugs with a high affinity for the androgen receptor. Commonly used cell culture techniques (MTT assay, colony-formation assay, soft-agar assay, wound healing assay, EdU staining, Annexin-V/PI staining) were employed to investigate the potential anti-carcinogenic effect of andarine on A549 cells. The expression levels of several genes involved in the cell cycle and apoptosis processes were determined by qPCR. Our findings demonstrate that andarine inhibited growth, migration, and proliferation while inducing apoptosis in lung cancer cells. Gene expression analysis revealed that andarine significantly upregulated the expression of BAX, CDKN1A, PUMA, and GADD45A while downregulating MKI67, BIRC5, and PCNA expression. Although there is no study on the utility of SARMs as inhibitors of lung cancer, we report the first study evaluating the potential anti-carcinogenic effects of andarine, a member of the SARMs, on lung cancer. Our results suggest that andarine could be considered as a promising drug candidate to test further for lung cancer treatment.

Published: April 2023

Nowadays, the use of green materials has been expanded for biomedical and bioengineering. Egg white (EW) is a low-cost and abundant candidate for various biomedical applications. In this study, a nanofibrous scaffold based on EW blended with polycaprolactone/gelatin (PCL/Gel) was fabricated using electrospinning. The fabricated samples were characterized using Physicochemical analyses including SEM, FT-IR spectroscopy, tensile assay, and contact angle measurement. The optimized samples were used as scaffolds for cell culture. The average diameter of prepared nanofibers measured 215.9 nm to 434.1 nm. The FT-IR and DSC assays showed the physical blending of EW with PCL/Gel was appropriate and there wasn’t a new chemical reaction between them. The contact angle test indicated the hydrophilicity of the scaffolds was decreased from 26.25º to 116.5º by increasing the EW amount in the PCL/Gel (0%-15%). Furthermore, the electrospun PCL/Gel nanofibrous mat with 10% EW exhibited better bioactivity than other samples with different amounts of EW. Therefore, adding 10% of EW to PCL/Gel nanofibers can improve the efficiency of fibroblast culture. This research introduced a nanofibrous scaffold for skin tissue engineering containing Gel and EW as low-cost and available materials that can be used for biological applications and also for productions like engineered leathers.

The applications of various clay minerals are related to their structural, physical and chemical characteristics. The physical and chemical properties of the clay minerals dictate their utilization in the industries and beneficiation required before usage. The study aimed at establishing the potentiality of acid activated clay mineral from Hadar, Afar, Ethiopia. XRD, SEM, EDXRF and FT-IR spectroscopies were employed to characterize the chemical compositions and interaction in the bentonite samples. The XRD results revealed that the native and activated bentonite clay contains similar minerals, such as; Montmorillonite [(Ca, Na) 0.33 (Al, Mg)2(Si4O10)(OH)2.nH2O], Quartz [SiO2], albite [NaAl2SiO6], zeolite [CaAl2O3.SiO2.nH2O], and aluminum silicate. Thus, attributes the bentonite clay was composed of SiO2 and Al2O3 indicating that it is an aluminosilicate mineral and the morphology of bentonite was supported by SEM. The chemical analysis by EDXRF revealed that the native bentonite consists of 58.18wt% (SiO2), 14.28 wt% (Al2O3) and Na2O > CaO are the major constituents of the clay with other oxides present in low amount. There was an increase in SiO2 content in activated bentonites, the Al2O3, Fe2O3, and MgO content have decreased by 48.56%, 66.36%, and 84.42%, respectively. The FTIR specta bands at 1627cm–1, and 1027cm−1 were attributed to Al-Mg-OH, Al-Al-OH, and Al-OH-O-Si stretching vibration and the reduction of the content of the octahedral cations is accompanied by a decrease of both OH bending vibrations at 1627 and 3401 cm−1. The FT-IR result is in clear agreement with the SEM, XRD and EDXRF studies which indicate sequential degradation of the clay sheet upon acid treatment. hence rendering the activated bentonite clay have accounted for their demand for different industrial applications such as; its use as detoxifier, sealant, binder, fillers for paper, pharmaceutical products, absorbent, adsorbent, catalyst, nanoclays, et.

Deforestation in Cameron Highlands, Malaysia has increased significantly in the past few years to accommodate the growing population of Cameron Highlands. This led to a rapid urbanisation in Cameron Highlands which increased anthropogenic activities, causing degradation of the natural environment. Such environmental changes highlight the necessity of wildlife and resource inventories of available forested areas to improve existing conservation and management plans, especially for threatened taxa such as the non-volant small mammals. However, very few studies are known to focus on the effect of deforestation on non-volant small mammals, especially in the adjacent forest. This survey aimed to document non-volant small mammals from four habitat types (restoration areas, boundary, disturbed and undisturbed areas) of Terla A and Bertam, and undisturbed forest of Bukit Bujang Forest Reserve, Cameron Highlands, Malaysia. Samplings were conducted in two phases between August 2020 to January 2021. A total of 80 live traps were deployed along the transect lines in all three study sites, and 10 camera traps were set randomly in each forested area. Results demonstrated that species diversity (H’) is higher at Terla A Forest Reserve compared to Bertam and Bukit Bujang Forest Reserve. In contrast, species diversity in the boundary area (S = 8, H’ = 2.025) and disturbed forest area (S = 8, H’ = 1.992) had similar number of species (S) compared to others study habitat; restoration area had the lowest species diversity (S = 3, H’ = 0.950). Berylmys bowersi was the most captured species from trappings and Lariscus insignis was the most frequently recorded species from camera trappings for all study sites. The results of the survey provided new information on non-volant small mammals in Cameron Highlands for future research, conservation, and management.

Freeze-process has been applied in preserving many fresh horticultural commodities addressed to the medium-distancing distribution. In this study, effect of freezing process and storage time on durian’s attributes degradation was observed. 100 durian fruits were treated with two-level combinations of freezing process. The first level involves the freezing of the said fruit at –15°C for two different freezing times, that is 10 min (treatment A) and 20 min (treatment B). Followed by frozen-storage for –10°C for 0, 10, 20 and 30 days. At different interval time, the frozen samples were thawed at 4°C for 24h. Then, physical, chemical, and sensory parameters were periodically assessed. The result showed that treatment B provide a significantly better output than treatment A. This is proven through a lower weight loss, brighter and lighter yellow of the pulp, softer pulp, lower value of moisture content on the pulp, and a remained stable of succinate acid’s profile. Furthermore, based on the preference evaluation test, the fruits were accepted by respondents.

Previous studies had reported antihyperglycemic activity in vitro, in vivo and in silico of red betel (Piper crocatum) extract, which was associated with its polyphenolic, tannins, alkaloids, and flavonoids compounds. This study aimed to determine blood glucose level, Langerhans pancreas, lipid profile and bodyweight of streptozotocin-induced diabetic rats after administrating red betel combination extract. Red betel combination extract is composed of red betel extract that was combined with ginger and cinnamon extracts. 16 male rats (Sprague Dawley) were divided randomly into two controls groups (Normal and diabetic groups; orally administered with 2 mL of aquadest for 14 days) and two extract groups (diabetic groups; orally administered with red betel combination extract 9 mL/kg BW and 13.5 mL/kg BW). Results showed that the administration of red betel combination extract for 14 days (9 mL/kg BW dosage) decreased the rat’s blood glucose level up to 55.42%, which was significantly different (p < 0.05) compared to the rat’s blood glucose levels on day 3. While the combination extract (dosages 9 mL/kg BW and 13.5 mL/kg BW) increased the numbers of rat Langerhans islets up to 10.9%–30.6%. The level of rat’s blood high-density lipoprotein (HDL) and triglyceride levels in the diabetic control group were significantly different (p < 0.05) compared to that of the diabetic with red betel combination extract and normal groups. The treatment orally with red betel combination extract (various dosages) for 14 days suppressed the weight loss of rats by 10%–11%.

In order to determine the safety level of water parameters and nutrients in the natural environment of fish and freshwater prawn in Nyatuh River, Terengganu, Malaysia, it is necessary to conduct an assessment of water quality parameters. Due to its important, a study was conducted to assess the water quality parameter and nutrients contents from Nyatuh River of Setiu Terengganu in relations to the population of freshwater prawn, Macrobrachium rosenbergii caught along the Nyatuh River basin. Total of four expeditions and five stations at different tidal condition for the water quality parameter were assessed during the study. From the results achieved, the overall temperature varied between (26.56°C–29.30°C), dissolved oxygen, DO (3.59 mg/L–6.50 mg/L), pH (4.99–7.01), salinity (0.01ppt–4.22ppt), depth (2.71 m–5.54 m) while for ammonia (0.01 mg/L–0.24 mg/L), nitrite (0.01 mg/L–0.05 mg/L) and phosphate (0.01 mg/L–0.12 mg/L). While the number of prawns caught are 176, 160, 102 and 68 for Expeditions 1, 2, 4 and 3, respectively. Possibly, the heterogeneous number of prawns caught is a result of significant differences in water level depth during high tides and low tides, as well as a fluctuation in the ammonia concentration levels in each of the stations and expeditions. For statistical analysis, the temperature showed no significant difference between the expedition, stations and tidal. That is p = 0.280, p > 0.05 and F = 1.206, respectively. While dissolved oxygen, DO, showed no significant difference as well, that is p = 0.714, p > 0.05 and F = 0.737. However, the level of water depth was significantly different between expedition, station and tidal, that is p = 0.000, p < 0.05 and F = 3.120. Ammonia, on the other hand shows no significant difference between expedition, station and tidal, that is p = 0.476, p > 0.05 and F = 0.973. The same goes for nitrite and phosphate concentration. There was no significant difference between expedition, stations and tidal, that is p = 0.569, p > 0.05 and F = 0.879 and p = 0.247, p > 0.05, F = 1.255, respectively. In Expedition 1, the good water quality parameter and very low ammonia concentration resulted in a larger prawn population as compared to other expeditions. The distribution or mixture of prawns caught is heterogeneous at different stations due to the significant differences in water depth and also to the fluctuation in water quality due to varying ammonia levels. In conclusion, the water quality in Nyatuh River fluctuated across expeditions, stations, and tides, as well as significant differences in water level depths between high and low tides. Due to the rapid growth and importance of industrial and aquaculture operations along the river, extra attention should be devoted to avoid the impact of excessive pollutant in order to protect the ecosystem.

The objective of this study was to investigate the mixed culture of Bacillus subtilis, B. licheniformis and B. megaterium to control acute hepatopancreatic necrosis disease (AHPND) or EMS (Early Mortality Syndrome) in white shrimp Litopenaeus vannamei as a model. The infected shrimps with Vibrio parahaemolyticus AHPND strain were divided into tanks and different feeding of either B. subtilis, B. licheniformis, B. megaterium or all Bacillus strains. The infected shrimps that were fed with a mixed culture of Bacillus showed significantly highest survival rate and revealed lower percent detection of V. parahaemolyticus AHPND strain by Polymerase Chain Reaction (PCR) (57.14%) with a small amount of viability count in their hepatopancreas. In contrast, the infected shrimps that were fed with each of B. subtilis, B. licheniformis or B. megaterium, revealed the spread of V. parahaemolyticus AHPND strain in all tissue by PCR detection (86.67%–100%) with a large amount of viability count (3.53 – 4.24 × 103 CFU/g). This study indicated that the mixed culture of Bacillus subtilis, B. licheniformis and B. megaterium could control the dissemination of V. parahaemolyticus in shrimps, especially in hepatopancreatic that is the target tissue of AHPND in white shrimp (L. vannamei). The result of this study revealed the efficiency and mechanism of the mixed culture of B. subtilis, B. licheniformis and B. megaterium to control the virulence of AHPND and support the application of this mixed culture in aquaculture of shrimp farms to avoid chemical and antibiotic treatment by using it as a biological control.

Oxidative stress and inflammation have been proven to be implicated in the pathogenesis of type 2 diabetes. Recent studies showed that Ethulia conyzoides had in-vitro antioxidant activity. This study investigated the in-vivo antidiabetic, antioxidant, and anti-inflammatory potential of the residual aqueous fraction of Ethulia conyzoides in type 2 diabetic-induced male Wistar rats. Sub-acute antidiabetic studies were done with varying doses (100, 200, and 400 mg/kg body weight) of residual aqueous fraction for 21 days. Blood glucose levels, serum insulin, and in vivo antioxidant and pro-inflammatory cytokines— tumour necrosis factor- ? (TNF-?) and interleukin-1? (IL-1?) —were measured at the end of the treatment. When rats were given different concentrations of residual aqueous fraction, there was a significant (p < 0.05) reduction in blood glucose, malondialdehyde (MDA), IL-1?, and TNF-? levels, as well as a significant (p < 0.05) increase in SOD (superoxide dismutase), catalase and insulin levels when compared to the diabetic control group. Furthermore, the 400 mg/kg body weight dosage concentration was found to be the most effective. This result suggests that the residual aqueous fraction of Ethulia conyzoides possesses significant antidiabetic, antioxidant and anti-inflammatory activities.

Transparent conducting oxide material, ZnO nanoparticles has been synthesized using inexpensive and eco-friendly synthesis procedures with less or environmental pollutants and no liquid waste products. The effect of the temperatures on the structural properties for the synthesized ZnO nanocrystals has been investigated. In this study, we report an easy, low-cost, re-producible method for synthesizing ZnO nanoparticles by means of the liquid phase method. The ZnO nanocrystals were synthesized using the wet chemical route and the effect of temperature variation on the structural properties of investigated synthesized using powder x-ray diffractogram (XRD). The temperatures for the synthesis were varied from 120 °C to 200 °C in steps of 20 °C. The results show that, during the first stage of the synthesis of ZnO (at 120 °C), the XRD diffraction pattern confirms the cubic structure of zinc peroxide and the XRD pattern of the samples obtained at temperatures of 140 °C, 160 °C, 180 °C and 200 °C were confirmed to be hexagonal (wurtzite) crystal structure of ZnO. The XRD diffraction patterns of the 140 °C and 160 °C samples show some impurity phases which were associated with the zinc acetate by-product which is a colloid complex of water and methyl succinate and were removed by evaporation as temperatures were increased to 180 °C and 200 °C respectively. As temperature increases, the peak of the diffractograms of the sample becomes sharper and narrow indicating a decrease in width. A shift in peak positions to higher angles was observed and the positional parameter, bond angle, β, average crystallite size, APF, number of unit cells and density generally increase with temperature. However, the lattice parameters ‘a’ and ‘c’, bond lengths b and b1, bond angle, α, dislocation density, strain and unit cell volume were found to generally decrease with temperature.

Published: April 2023

The article briefly gives the history of the creation of the Azerbaijan National Museum of Art, one of the largest museums in the country. The museum has a rich collection of Russian, Western European, Eastern and Azerbaijani art. The collection has been formed throughout the existence of the museum, but its foundation was laid back in the Azgosmusey. A certain part of the collection is made up of exhibits transferred to the museum during the USSR period, a cultural policy that relied on the education of the masses, regardless of nationality and region. A descriptive description of the exhibition activities of the museum is given, in which both collections of Russian and foreign museums were exhibited in different years. In various years, the museum hosted exhibitions of the fraternal republics, as well as China, India, Iran. After each exhibition, the museum’s collection was replenished with new exhibits. The museum constantly held and held personal exhibitions of representatives of various schools of painting in Azerbaijan. The country’s artists are proud that their paintings are exhibited and stored in one of the country’s major museums. In the context of the article, a special place is given to the work of the first theater artist R.Mustafayev, whose name the museum bore for many decades, and whose works are kept in his collection. Unfortunately, the name of this talented artist is little known to the younger generation, although his contribution to the development of national scenography and the protection of architectural monuments is invaluable. Thanks to his artistic flair, the performances “Koroglu” and “Arshin Mal Alan” designed by him have been successfully staged on the stage of various theaters. Тhe analysis of his work is an important thematic contribution to the history of the study of the Azerbaijan National Museum of Art.

Authors: Fang Jiangtao , Tang Liyuan
Published: April 2023

Soil moisture content improvement is a key process in agricultural production and food security in arid and semi-arid regions. The interaction effect of crop water requirement (CWR) and soil texture on water productivity was evaluated in Harbin, Heilongjiang province, China. A field experiment with two scenarios of compost application (0, 25 ton/ha) and three levels of irrigation policies (deficit irrigation (DI = 0.75CWR), regular irrigation (RI = CWR), and full irrigation (FI = 1.25CWR)) was planned in three replications during 2021–2022. Water productivity was simulated as a criterion to improve the irrigation time for increasing the final biomass. Four strategic crops including potato, corn, wheat, and barley were incorporated into the daily simulation system. Furthermore, a machine-learning random forest algorithm was used to find the best irrigation times. The results showed that the use of adjusted irrigation time and improved soil texture can increase water productivity by reducing evaporation and deep percolation and increasing actual biomass. Estimation of irrigation time in a learning-based method will be optimal when plant growth and soil moisture are monitored on a daily basis.

Understanding the urban environment and the health status of residents is necessary for appropriate administrative services and regional management. This study used indicator scores derived from the area statistics of cities in the Tokyo metropolitan area to identify factors that affect health status. Indices were classified into two groups: health-related and non-health-related. The index values of each group served as the observed variables and were statistically standardized. The relationship between the two groups was analyzed using canonical correlation analysis. The results indicate that social infrastructure and daily travel behavior affect the health status of residents, possibly by promoting physical activity. Furthermore, characteristics of the urban environment and travel behavior were strongly associated with the ratio of deaths due to lifestyle-related diseases.
