Published: March 2024

Water is the most widespread substance found in the natural environment; liquid, solid and invisible vapour. Fresh water is a crucial resource for human life and natural systems. The quality of water is usually described according to its physical, chemical and biological characteristics. Rapid industrialization and use of chemical fertilizers and pesticides in agriculture are causing heavy and varied pollution in aquatic environments leading to the deterioration in water quality and aquatic biota. Planktons are taxonomically diverse, composed of plants, animals, bacteria and viruses. Globally the biomasses of phytoplankton and zooplankton are about equal, although the doubling time of zooplankton is considerably longer than for phytoplankton. The present investigation was carried out to assess the water quality and plankton diversity in Anchuthengu lake, Thiruvananthapuram, Kerala, India. Analysis of water quality was done with respect to eleven important physicochemical parameters like air and surface water temperature, pH, TDS, salinity, electrical conductivity, alkalinity, hardness, free CO2, DO and BOD. Conductivity shows high positive correlation with alkalinity and hardness. Alkalinity is positively correlated with hardness. The aquatic flora and fauna in the lake may grow well because the DO value in the current study was over 5 mg/L, and the BOD value also indicates that the lake is less contaminated.. The dominated plankton species identified in the present study were Spirogyra, Chlorella, Navicula, Pinnularia, Oscillatoria, Closterium, Cosmerium.

Published: March 2024

Evaporated milk is used in many fields due to their various nutritional and functional properties. Evaporated milk widely finds its application in infant food formulas, as well as used for drinking after dilution, for cooking or as a coffee whitener/creamer. Evaporated milk has a higher concentration of milk proteins which leads to one of the biggest challenges that is, heat-induced coagulation due to the denaturation of milk proteins, particularly the whey proteins, and their interactions during the intense sterilization operation that is typically used to ensure a longer shelf-life for these products. As this phenomenon highly influences the product quality and production equipment, it is of great importance to improve the heat stability of the milk-proteins. The present article reviews the recent advances in different techniques that improves the heat stability of evaporated milk.
Geo thermal energy - Clean, safe and renewable - A review study
Authors: Nath Alok , Patel M. B. , Mohanta Bijayalaxmi
Published: March 2024

The rising demand of energy and exhausting sources of fossil fuels has compelled people all over the world towards a renewable, clean energy source i.e. geothermal energy. Geothermal resources are reservoirs of hot water that exist or are human made at varying temperatures and depths below the Earth’s surface. In side the great depths of the Earth, the temperature (1,250 °C) and pressure is sufficient to melt rock into magma which is termed as lava (750°C) once it comes out of the crust. This heat content is harnessed as geothermal energy and utilized for heat applications as well as generation of power. The majority of the world’s geothermal resources are located in the tropical Pacific Rim (Ring of Fire). The types of geothermal resources are categorized as convective hydrothermal systems; EGSs; conductive sedimentary systems; coproduction, with water from oil and gas fields; geopressure systems; and magma energy. Mostly, geothermal fluid can be used directly or indirectly depending on the enthalpy. High-temperature geothermal resources are primarily used for energy production, whereas low to medium ones are particularly equipped for non-electric applications. The extraction of geothermal energy from the grounds leads to a release of greenhouse gases like hydrogen sulfide, carbon dioxide, methane and ammonia etc. However, the amount of gas released is significantly lower than in the case of fossil fuels. Moreover, geothermal energy has proven its capacity to be a reliable, clean, and uninterrupted sustainable renewable energy.

Published: March 2024

Identifying the precise moment before the onset of hepatocellular carcinoma (HCC) remains a significant challenge in the medical field. The existing biomarkers fall short of pinpointing the critical point preceding HCC formation. This study aimed to determine the exact tipping point for the transition from cirrhosis to HCC, identify the core Dynamic Network Biomarker (DNB), and elucidate its regulatory effects on HCC. A spontaneous HCC mouse model was established to mimic HCC formation in patients with chronic hepatitis. Using the DNB method, C1q and tumor necrosis factor (TNF) related 1 (C1QTNF1) protein was identified as the key DNB at the crucial tipping time of spontaneous HCC development. Both in vitro and in vivo studies showed that C1QTNF1 could inhibit tumor growth. Overexpression of C1QTNF1 before the tipping point effectively prevented HCC occurrence. Patients with elevated C1QTNF1 expression demonstrated improved overall survival (OS) (P = 0.03) and disease-free survival (DFS) (P = 0.03). The diagnostic value of C1QTNF1 was comparable to that of alpha-fetoprotein (AFP) (area under the curve [AUC] = 0.84; sensitivity 85%; specificity 80%). Furthermore, our research indicated that platelet-expressed C1QTNF1 is involved in cancer-associated signaling pathways. Our findings introduce a novel perspective by highlighting C1QTNF1 as the pivotal biomarker at the tipping point of primary HCC formation using DNB. We propose C1QTNF1 as a prognostic biomarker for HCC, potentially influencing tumor development through a platelet-related cancer signaling pathway.

Calcined clay, a widely studied supplementary cementitious material, has shown positive impacts on concrete's microstructural properties, strength development, and durability. The variation in raw clay mineral concentration across different locations influences the optimal calcination temperature needed to activate its pozzolanic reactivity. This investigation focuses on studying the effects of calcination temperature on the characterization and pozzolanic reactivity of Nigerian Kaolinite clay. The clay was calcined at temperatures ranging from 600˚C to 900˚C for 2 hours. Characterization involved X-ray Diffraction (XRD), X-ray Fluorescence (XRF), and Scanning Electron Microscope (SEM) analyses. Blended mixtures, incorporating 10%, 20%, 30%, and 40% metakaolin as cement replacement, were assessed for workability, strength, and durability properties at 7, 14, 28, and 56 days to determine the clay's pozzolanic reactivity. XRF categorized the metakaolin as a class N pozzolan, while XRD indicated that 800˚C for 2 hours was necessary for complete dihydroxylation. Compressive, tensile, and sulfate resistance tests confirmed that treating the clay at 800˚C for 2 hours optimized its performance. The mix with 10% metakaolin outperformed the control by 6.4%, 14.7%, and 14.1% in compressive strength at 14th, 28th, and 56th days, respectively. While the best performance was at 10% replacement, levels up to 30% also demonstrated satisfactory results compared to the control, showing potential for achieving desired strengths. Linear regression models were also developed to establish the relationship between compressive and split tensile strengths across curing periods. The resulting equations demonstrate excellent predictive performance with correlation coefficients ranging from 0.928 to 0.991.

A Guideline for Greenhouse Gas Emission Reduction and Carbon Sequestration in Forest Sector Based on Thailand Voluntary Emission Reduction Programme
Authors: Uttaruk Yannawut , Khoa Phung Van , Laosuwan Teerawong
Published: March 2024

Currently climate change and global warming have significant impact on the environment toward biodiversity and human quality of life. Major cause derives from human activities that produce greenhouse gas emission especially the diffusion of carbon dioxide to the atmosphere. One way to address global warming is to increase the absorption potential of greenhouse gases, especially carbon dioxide. The best natural method is forest adsorption whereby trees absorb carbon dioxide and store it in the form of biomass through photosynthesis. Therefore, forests are a highly efficient source of carbon sinks. The main objective of this research was to implement a methodology for greenhouse gas reduction and carbon sequestration assessments in forest sector according to Thailand's standards known as the Thailand Voluntary Emission Reduction Program (T-VER). According to climate change, reduction of greenhouse gas process will use methodology of T-VER-METH-FOR-01 Version 2 (Sustainable Forestation)andT-VER-TOOL-FOR/AGR-01 Version 2(Calculation for Carbon Sequestration). The Baseline Sequestration/Emissionand Project Sequestration/ Emission as well as plant diversity assessment in project area as greenhouse gas activity will be used for the calculation. The results of this development of prototype project could be used for concluding content of greenhouse gas from 134.72 ha of the research area and it was shown that Baseline Sequestration was 19,618.95 tCO2e. When calculating Project Sequestration for 10 years, carbon content could be increased by 27,617.95tCO2e calculated to be 800.61tCO2e/yr. Therefore, total Project Sequestration was 8,006.13tCO2e.

Published: March 2024

Objective. To work out the index for diagnosing non-alcoholic fatty liver disease (NAFLD) in women with metabolic syndrome (MS) in postmenopause using generally available markers.
Materials and methods. 62 females with NAFLD and MS in early postreproductive period took part in the study. They were compared to 24 relatively healthy females not suffering from obesity in postmenopause. The average age of the patients was 49,9 ± 1,1. Hepatic steatosis was diagnosed by ultrasound examination. The mathematic model of hepatic steatosis index (HSI) calculation included: body mass index (BMI), waist size (WS), triglycerides and low-density lipoproteins (LDL).
Results. BMI and WS in patients with MS and NAFLD in postmenopause were considerably more than in relatively healthy women. Hypertriglyceridemia and an increase of LDL in blood serum were noted in patients with steatosis. Biometric and laboratory data were included in the mathematical formula which allows to calculate HSI. With HSI 0,5 and more NAFLD is diagnosed in women in post menopause, when HSI is lower than 0,5 it is not diagnosed. Indicators of sensitivity and specificity of the method were 98,4 % and 95,85 % respectively.
Conclusions. The minimally invasive method suggested above allows to reveal hepatic steatosis in females with MS in early postreproductive period. High diagnostic characteristics of the method are worth mentioning, as well as the possibility to be widely used thanks to simple biometric and laboratory data employed.

Objective. To determine the frequency of cervical intraepithelial neoplasia among female citizens in Yekaterinburg.
Materials and methods. The retrospective analysis of the report forms of the cervical pathology office in Yekaterinburg Perinatal Center from January to September 2022 was carried out. Statistical data processing was conducted using descriptive statistical methods in the Excel programme.
Results. 255 cases of precancerous cervical diseases and 7 cases of cervical cancer were revealed within 9 months of monitoring, among them 24 patients with precancerous pathology and 4 with cervical cancer had previously been followed up by a specialist. Most cases of cervical pathology were revealed in patients over 40.
Conclusions. The women's consultations of Verkh-Isetsky and Leninsky districts refer patients to the specialized cervical pathology office most actively. Patients of the cervical pathology office are provided with the full range of therapeutic and diagnostic procedures, with colposcopy being most often performed (27 % of cases). The dispensary group of patients of the cervical pathology office is mainly represented by women with cervical dysplasia of the 2nd degree (HSIL, CIN II) – 43.5 %.

Objective. To study the features of hypertensive disorders formation in pregnancy depending on the period and clinical form on the example of the population of Sverdlovsk region.
Materials and methods. The outcomes of 217 pregnant women with moderate and severe preeclampsia and gestational hypertension were analyzed (41, 74, and 102 cases, respectively).
Results. The severe preeclampsia group had the highest rate of fetal growth restriction (14.6 %), low birth weight -2045 g (1640–2650), preterm delivery (63.4 %), and cesarean delivery (87.8 %). A detailed analysis of 28 cases of gestational hypertension lasting up to 34 weeks was performed. The analysis revealed significant challenges in the differential diagnosis of this pregnancy complication, not only in terms of clinical manifestations, but also in terms of timely diagnosis in general.
Conclusions. The findings of this study spark a debate over the use of severity-based classification in clinical practice, which lessens the doctor's vigilance in milder forms that, however, result in equally serious complications. This raises the question of whether unified tactical approaches should be used in this pathology.

Objective. To study the dynamics of the main markers of protein metabolism and microelements in patients with a new coronavirus infection.
Materials and methods. A prospective clinical and laboratory study of the dynamics of the main markers of protein metabolism and microelements was carried out in 62 patients with a new coronavirus infection complicated by the development of pneumonia with a moderate course on the basis of Perm regional clinical hospital of infectious diseases in 2021–2022. On the 1st and 14th days of hospitalization all patients underwent general clinical and biochemical studies. The concentrations of total protein, albumin, transferrin, Fe, Zn and Cu was also determined. Statistic processing of the results was carried out using Microsoft Excel 2000 and “Statistica 10”.
Results. A decrease in visceral pool proteins was revealed. It indicated their active consumption and formation of hypermetabolism - hypercatabolism syndrome in a moderate course of the infection. A progressive deficiency of Fe and Zn, correlating with life-threatening complications and deaths was revealed.
Conclusions. The course of a new coronavirus infection contributes to the development of metabolic disorders, and the identified deficiency of macro- and microelements is a predictor of a severe course of the infection.

Objective. To study the association of polymorphic variants HHIP, ADRB2 and IL-33 genes with phenotypes of clinical course of bronchial asthma in children and effective treatment.
Materials and methods. 90 patients aged from 5 to 17 with the diagnosis of bronchial asthma were included in the investigation. Diagnostic procedures were carried out in all the patients. They included the study of genetic polymorphism of HHIP, ADRB2 and IL-33 genes to establish the association with the clinical phenotypes, findings of laboratory and instrumental study determining the course of bronchial asthma and the degree of its control.
Results. The study of polymorphism of HHIP, ADRB2 and IL-33 genes in children with bronchial asthma with different phenotypes of the disease revealed the association of genetic polymorphism with the severity of course of the disease as well as concomitant diseases. It was determined that allele T of genetic variant rs12504628 (TC) of HHIP gene reduces the risk of a severe course of BA. Its protective role in the development of drug allergy was also proved. Genotype AA of ADRB2 gene is associated with reduced risks of the development of congenital defects of the tracheobronchial tree in BA. Polymorphic variants in the 4th and 6th exon of IL-33 gene are more frequently associated with moderate and severe course of asthma and base substitution in the 4th and 6th exon are associated with the severe course.
Conclusions. Associations of polymorphic variants of HHIP, ADRB2 and IL-33 genes with clinical manifestations of BA in children are determined in this study. They can be considered in a personalized monitoring of the patients and can help to control the disease totally.

Objective. To study the stress-strain state of demineralized tooth enamel after its impregnation with a low-viscosity composite in a long-term period of functioning in the oral cavity in a series of equivalent cyclic tests; to study the correlation of the experimental results with clinical observations of the treatment of enamel caries using a modified infiltration technique.
Materials and methods. The parameters of laser holographic interferometry and atomic force microscopy, reflecting the timing, type and severity of deformation defects in samples of demineralized tooth enamel were analyzed in a series of equivalent cyclic tests. During the experiment the samples underwent classical infiltration with composite using ICON technology (main group) and a 2-stage enamel caries treatment technique, including carrying out a time-modified conditioning of classical infiltration and the final stage (stages) of enamel coating with a bioactive hybrid glass ionomer (comparison group).
Results. The first signs of the deformation defects generation in demineralized enamel filtered on the classical method (the appearance of perifocal microcracks) were recorded in 11.2 % of the tested samples after 0.9 · 106 cycles (equivalent to 9 months of functioning of a tooth with treated enamel caries in the oral cavity), during further cyclic tests the percentage of samples with local defects increased progressively. Signs of a violation of the stress-strain state in the enamel after combined treatment (samples of the comparison group) were revealed in cycles corresponding to 2–3 years of being in an artificial environment of the oral cavity. Experimental data correlated with the clinical observations both in time and frequency of complications (secondary/recurrent caries) in the long term after treatment of enamel caries by various methods.
Conclusions. In the process of equivalent cyclic tests, heterogeneous elastic-plastic deformations develop in the thickness of a section of demineralized enamel impregnated with a flowing composite and along its perifocal zones, most pronounced at the interface between intact and treated enamel, which leads to the development of local defects, delaminations, cracks, and destruction of the structurally heterogeneous environment of tooth enamel. According to the results of the comparative analysis, the most favorable results in terms of the timing of development, frequency and severity of deformation defects were obtained in samples of demineralized enamel after its treatment using a modified caries infiltration technique followed by coating with a bioactive hybrid glass ionomer.
Clinical and morphological features and unsolved issues in diagnosis of aggressive forms of papillary thyroid carcinoma

Published: March 2024

Differentiated thyroid cancer (DTC) is a disease with a favorable clinical course and high survival rate compared to other epithelial tumors. The majority of DTC (up to 85 %) is represented by various subtypes of papillary thyroid cancer (PTC). Aggressive forms of PTC characterized by early lymphogenous and hematogenous metastasis, low avidity to radioiodine therapy (RIT), low relapse-free survival rates and high mortality rate compared to other types of PTC occur among them. Preoperative diagnosis of PTC is based on the results of ultrasound (US) examination and fine-needle aspiration biopsy (FNA) with cytological examination of the aspirate. At the same time, the capabilities of cytological examination in determining the histological type of PTC are limited and it does not allow to predict its aggressiveness and plan adequate treatment. Molecular genetic tests of the tumor cytological and morphological material are effective in prognosis of aggressiveness of PTC due to the determination of specific mutations in the BRAF, TERT, RAS genes and the quantitative expression of oncogenic and tumor suppressive microRNAs. Some of these indicators are already used in the morphological classification of tumors of the endocrine system.
At the same time, there are contradictory data concerning the connection of the molecular genetic portrait of PTC, the clinical manifestations of its aggressiveness (extrathyroidal invasion, early metastasis, and radioiodine resistance) and its pathomorphological structure. We tried to summarize and analyze the literature data regarding the diagnosis of aggressive variants of PTC.
