Fatty acids, as part of cell membranes, determine their fluidity and dielectric constant. In addition, they play an important role in human and animal nutrition. This work examines the composition and fatty acid content of dried higher aquatic plants from Lake Kotokel (Republic of Buryatia, Russia) and their potential as a raw material for the production of feed and biologically active food supplements. A modified Bligh-Dyer method was used to extract lipid fraction. Fatty acids in the form of their methyl esters were analysed by gas chromatography–mass spectrometry. Palmitic C16:0 acid was the main saturated fatty acid found in Myriophyllum sibiricum, Elodea canadensis, Persicaria amphibia and Potamogeton perfoliatus in Lake Kotokel. The main unsaturated acid found in plants, regardless of their type, was the α-linolenic C18:3-ω3 acid. In addition, a relatively high content of stearic C18:0, myristic C14:0 and pentadecanoic C15:0 acids was noted. Branched acids (i-C14:0, i-C15:0, i-C16:0, i-C17:0, i-C20:0, a/i-C15:0, a/i-C17:0 and 10Me-C16:0) and odd carbon numbered acids (C13:0, C15:0, C17:0, C19:0, C21:0 and C23:0) were identified. An analysis of the authors’ and literature data revealed that the studied species of higher aquatic plants in reservoirs in the Asian part of Russia are characterised by a high content of α-linolenic C18:3-ω3 (up to 56%) and a low content of oleic C18:1-ω9 (up to 1.81%) acids. The content of α-linolenic C18:3-ω3 acid in plants from reservoirs in the European part of Russia was lower (up to 42%), while that of oleic acid C18:1-ω9 was higher (up to 14%).

Published: March 2024

The study set out to extract various types of hydrocarbons from model fuels using deep eutectic solvents based on glycerol. These solvents were synthesised by mixing glycerol as acting as a hydrogen bond donor with ammonium chloride or triethylammonium acetate [tea] [AcO]- acting as a hydrogen bond acceptor at room temperature in a volume ratio of 1:6. A mixture of n-decane and n-hexadecane was selected as components of the model fuel. For the extraction of mixtures of benzene, ethylbenzene (5%), p-, m-, o-cresol, fluorenone (3.5%) and petroleum acids (25%), these deep eutectic solvents were used at room temperature, as well as at a temperature of 60°C, and at atmospheric pressure. Extraction efficiency was evaluated by [1]NMR spectroscopy. The results demonstrated the complete single-stage extraction of p-, m- and o-cresols from the model fuel using the studied deep eutectic solvents. A deep eutectic solvent based on glycerol and triethylammonium acetate was found to have the highest extraction efficiency. The recovery rates for benzene, ethylbenzene, and fluorenone at room temperature are achieved in 3 hours of stirring (75, 25, and 53%, respectively). M- and o-cresols were fully recovered in 1 hour in a single step using a deep eutectic solvent based on triethylammonium acetate, while complete extraction of aromatic acids from a mixture of petroleum acids in model fuel was achieved using a deep eutectic solvent obtained by mixing ammonium chloride and glycerol.
Fluids in the shallow mantle of southeastern Australia: Insights from phase equilibria
Authors: Lamb William M. , Hunt Lindsey E. , Popp Robert K. 
Published: March 2024

Abstract
Small amounts of water (tens to hundreds of parts per million) can have a profound effect on the properties of mantle peridotites, including viscosities, conductivities, and melting temperatures. Measuring the water content of nominally anhydrous minerals (NAMs) has provided insight into the amounts of water contained within mantle rocks. However, converting from NAM water contents to the activity of H2O is non-trivial. Equilibria involving amphibole can be used to determine values of the activity of H2O (aH2O) at the time of mineral equilibration. This approach yields low values of the activity of H2O (&lt;0.3) for four peridotite xenoliths from Southeastern Australia. These four xenoliths also record values of oxygen fugacity (fO2) that range from –0.2 to –1.2 log units below the fayalitemagnetite-quartz buffer. All these values of fO2 are inconsistent with the presence of a CH4-rich fluid (too oxidizing), and the lowest value of oxygen fugacity, as recorded by one sample, is inconsistent with the presence of a CO2-rich fluid.

Purpose: to evaluate the ocular surface changes (OSC) in seasonal and chronic allergic blepharoconjunctivitis (ABC) under dry eye (DE) conditions and to consider therapeutic possibilities.Materials and methods. 60 patients with seasonal ABC and mild DE syndrome (group 1) and 50 patients with chronic ABC and moderate DE syndrome (group 2) were tested for lipid deficiency (LD; negative lipid-interference test), aqua-deficiency (AD; inferior tear meniscus height < 250 ﬁm), and mucose deficiency (Bijsterveld`s xerosis index > 3 scores; XI, scores), Ocular surface disease index (OSDI), tear film break-up time (TBUT, seconds), meibomian gland dysfunction (MGD) according to Korb, taking into account the proportion of MGD (%) and its severity (MGDS, scores), and the “lid-wiper” symptom (LWS, scores) Statistics: M ± s; Mann — Whitney U-test; differences were statistically significant at p < 0.05.Results. LD was diagnosed in 65% of the 1st group patients (OSDI 32.3 ± 4.2, TBUT 6.5 ± 0.6, TMH 363.4 ± 43.96, XI 2.1 ± 0.4, MGDproportion — 41.02 %, LWS 1.1 ± 0.2). LD and MD were detected in 35 % of 1st group patients (OSDI 41.3 ± 5.7, TBUT 5.7 ± 0.5, TMH 332.9 ± 29.9, XI 4.2 ± 0.7, MGD proportion — 61.9 %, LWS 1.24 ± 0.4). The differences in OSDI, TBUT and XI values between DE patients with LD and DE patients with LD and MD were statistically significant. LD and AD were diagnosed in 48 % of 2nd group (OSDI 48.5 ± 6.4, TBUT 5.5 ± 0.6, TMH 192.3 ± 20.8, XI 2.5 ± 0.5, MGDS 1.8 ± 0.4, LWS 1.9 ± 0.3). LD, AD and MD were detected in 52 % of the 2nd group patients (OSDI 57.5 ± 5.8, TBUT 4.6 ± 0.6, TMH 177.7 ± 16.9, XI 5.5 ± 0.6, MGD-S 2.2 ± 0.4, LWS 2.3 ± 0.4). The differences in OSDI, TBUT and XI values between DE patients with LD-AD combination and DE patients with LD-AD-MD were statistically significant.Conclusion. OSC included lipid deficiency (65 %) and lipid-mucose deficiency (35 %) in S-ABC patients; OSC were represented by lipid-aqua-deficiency (48 %) and lipid-aqua-mucose-deficiency (52 %) in C-ABC patients. In our opinion, the diagnostics of these clinical variants of OSP diagnosis, opens up opportunities for differentiated tear replacement therapy. MGD was diagnosed in one half of S-ABC patients and in all C-ABC patients, which we believe determines another possible therapy direction — eyelid therapeutic hygiene aimed at MGD relieving and lipid deficiency compensation.

Nomad livestock farming is an extra raw material resource for regions with harsh climate. Foods based on meat of indigenous animals expand the range of products with high consumer properties. The quality and safety of meat products usually depend on the brine. The present research featured the effect of brine with Island moss (Cetrária islándica (L.) Ach.) on the sensory profile and microbiological safety of meat products.
The study involved meat of two-year-old indigenous cows, as well as multicomponent antibacterial and standard extrusion brines. The brine was injected with a syringe-injector with a hollow perforated needle at a 20 mm pitch. The tenderization took place in a universal express tenderizer with a rotation speed of 16 rpm and lasted for 10 h. The shelf-life was determined based the on microbiological, chemical, and sensory indicators.
By the end of the reserve shelf-life, the total microbial count was 1.2×103 CFU/g in the control and 1.0×103 CFU/g in the experimental sample. No opportunistic pathogenic bacteria or microorganisms were detected. No opportunistic pathogenic microorganisms were revealed when the microbiological parameters were studied in standard quantities and in quantities increased by an order of magnitude.
The changes in acid and peroxide numbers during storage indicated a stable oxidation of the fat component in the experimental sample. Its sensory evaluation exceeded the control sample by 0.9 points in terms color, texture, and smell. The meat marinated with C. islándica compiled with the quality standard and had a shelf-life which exceeded that of the traditionally-marinated meat by 5 days.
Express Diagnostics of Bankruptcy Risks Based on a Selective-Indicative Model
Authors: Chernichenko Svetlana , Kotov Roman 
Published: March 2024

Effective bankruptcy risk diagnostics may prevent a financial crisis in Russia’s national economy. The article introduces a novel express tool for bankruptcy diagnostics based on early recognition of alert signs, crisis fields, and preliminary pre-crisis assessment. The tool is a selective-indicative model with regional and industrial specifications.
Regional and industrial exhibitors served as benchmark indicators. The empirical material included statistics, reference materials, and financial reports from agricultural organizations in the period of external economic shocks (2014–2022), Kemerovo region, Russia.
First, the alert signals of bankruptcy risk were identified based on 22 original methods of financial crisis forecasting. After that, they were assessed for practical popularity. The identified default risk signals were linked to the existing criteria of financial insolvency, subjected to economic interpretation, and classified. After fixing the analytical reference vectors, the authors identified the share of each indicator. By determining the latest results of model exponents, they ensured the direction of analytical reference vectors to maximize the disabled function. The next stage involved systematization and synthesis of alert signals into a diagnostic model to be developed into a gradation indicator. After fixing the signal analytical base, the model was tested to formulate conclusions about its adaptability in the current economy.
The resulting model relied on the share of each alert signal of bankruptcy risk in the rating number. It may improve the quality of predictive diagnostics. As the model needs few exponents, it provides a high-speed crisis analysis.

ABSTRACT

Health authorities are particularly concerned about water security in Enugu, southeast Nigeria and heavy metal (HM) pollution. The HM profiles of 51 samples collected from 17 different commercial bottled water brands in Enugu were examined using an flame atomic absorption spectroscopy. Cd, Cr, Cu, Pb, Ni, and Zn had mean values of 0.15 ± 0.03, 0.03 ± 0.02, 0.16 ± 0.03, 0.13 ± 0.02, and 0.02 ± 0.01 mg/L, respectively. The highest levels of Pb2+ were 0.27 mg/L in Exalté, Ni2+ 0.26 mg/L in Jasmine, Cd2+ 0.36 mg/L in Ezbon, Cr3+ 0.07 mg/L in Trinity, Cu2+ 0.04 mg/L in Bigi, and Zn2+ 0.02 mg/L in Aquarapha. The amounts of Cr, Cu, and Zn were below the allowable limits; nevertheless, the Pb content in eight bottled water samples exceeded both the Nigerian and World Health Organization (WHO)/U.S. Environmental Protection Agency (USEPA) permissible limits. The Cd2+ and Ni2+ levels in the 11th and 4th bottled water samples were above the WHO/USEPA-approved limits. Statistical evaluation revealed significant differences in the amounts of HM ions in the samples (p &lt; 0.05). The findings indicated that concentration levels of Cd2+ Ni2+, and Pb2+ pose a public health concern that needs to be addressed due to potential risk to consumer health.
Revisiting Waist Circumference: A Hypertension Risk Factor that
Requires a More In-depth Understanding
Authors: Su Yue , Sun Jin-yu , Su Zhen-yang , Sun Wei 
Published: March 2024

Abstract:
As a major cause of various cardiovascular diseases, the prevalence of hypertension
has been increasing in the past 30 years, leading to significant socioeconomic and health burdens.
Obesity is one of the major risk factors for hypertension. Body mass index (BMI) is the
most used anthropometric index to measure obesity in clinical practice and to assess the risk of
obesity-related diseases. However, obesity is a heterogeneous disease, and the accumulation of
fat in different body regions leads to differences in cardiovascular and metabolic risks. BMI only
reflects the overall obesity but does not consider the distribution of fat and muscle mass. The
limitation of BMI makes it insufficient to assess the risk of hypertension attributed to obesity. In
addition, waist circumference is an easily obtainable anthropometric index to evaluate abdominal
fat distribution. High waist circumference is an independent risk factor for various cardiovascular
diseases and all-cause mortality regardless of BMI. Preliminary data indicate that
waist circumference is significantly associated with the risk of hypertension at different BMI
levels. However, routine measurement of waist circumference is currently not required in current
clinical guidelines or is only recommended for obese populations, indicating an insufficient
understanding of waist circumference. In this review, we summarize the measurement methods
and diagnostic thresholds of waist circumference for abdominal obesity, the trend of central
obesity prevalence, the superiority of waist circumference over other anthropometric indices,
and recent cross-sectional and longitudinal studies on the association between obesity and hypertension.
The Association of Body Composition Parameters Measured by Computed
Tomography with Cancer Stage, Prognosis, and Survival in Patients with Renal
Cell Carcinoma
Authors: Gur Ozcan Seray Gizem , Barali Deniz , Erkan Anil 
Published: March 2024

Objective::
This study aims to investigate the association of preoperative body composition parameters, measured by computed tomography in patients
undergoing surgery for renal cell carcinoma, with its stage and to survey the relationship with postoperative hospitalization duration and survival.

Methods::
Demographic data, pathology results, cancer stages, and hospitalization duration of 104 patients undergoing surgery at the urology clinic due to
renal cell carcinoma between 2019 and 2023 were analyzed retrospectively. On computed tomography scans acquired during diagnosis, visceral
adipose tissue, subcutaneous adipose tissue, total adipose tissue, and skeletal muscle area were measured. The ratios of body composition
parameters were computed.

Results::
When the correlation between survival time and body composition in deceased patients was analysed, a moderate but significant correlation was
observed between skeletal muscle area value and total adipose tissue / skeletal muscle area ratio (r=0.630, p=0.001; r=0.598, p=0.002). A
significant and strong correlation was observed between total adipose tissue value and survival (r=0.704, p<0.001). Subcutaneous adipose tissue /
skeletal muscle area was found to be an independent risk factor associated with mortality, and a ratio of 0.98 or less increased the mortality risk
approximately 16-fold.

Conclusion::
The relationship between body composition parameters measured by computed tomography, which can be easily evaluated pre-treatment, and
mortality, postoperative recovery and length of hospital stay can be evaluated, giving clinicians an idea about the potential difficulties that patients
may encounter during the treatment process. For this purpose, the subcutaneous adipose tissue / skeletal muscle area ratio is the most helpful
parameter that can be used.

Published: March 2024

Penelitian ini bertujuan untuk; 1) mengetahui makna media online Change.org sebagai pilar kelima demokrasi yang dapat digunakan masyarakat untuk menyampaikan aspirasi; 2) konsep demokrasi yang diwacanakan dalam media online Change.org. Pendekatan penelitian yang digunakan yaitu kualitatif dengan metode analisis wacana model Teun A. van Dijk. Sedangkan objek penelitiannya adalah media online Change.org Indonesia. Pengumpulan data dilakukan dengan analisis teks, wawancara, dan studi pustaka. Teks yang dianalisis petisi berjudul “Selamatkan Beruang Kelaparan di Kebun Binatang Bandung” yang dibuat oleh Yayasan Scorpion Indonesia. Informan yang diwawancarai yaitu pengelola Change.org Indonesia, pembuat petisi, dan pengguna Change.org. Analisis data dilakukan melalui tahap-tahap analisis teks, kognisi sosial, dan konteks sosial. Pemeriksaan keabsahan data dilakukan dengan uji kredibilitas. Hasil penelitian menunjukkan, penyaluran aspirasi melalui Change.org dapat dilakukan dengan pembuatan petisi, penandatanganan petisi, dan aspirasi yang disampaikan melalui kolom komentar. Petisi dibuat oleh masyarakat dengan target yang spesifik serta berisi tuntutan yang jelas. Pihak Change.org memfilter petisi yang sekiranya melanggar ketentuan. Setelah petisi dibuat, diperlukan mobilisasi khalayak dengan cara eskalasi melalui media lain maupun aksi offline karena Change.org tidak dapat bekerja sendiri. Cara ini dilakukan supaya banyak orang yang ikut berpartisipasi menandatangani petisi. Demokrasi yang terbentuk merupakan demokrasi partisan yang disampaikan melalui media digital. Melalui media ini masyarakat tidak perlu berpartisipasi secara fisik. Media digital juga lebih memungkinkan tindakan kolektif warga karena sifatnya yang mudah diakses siapapun dan kapanpun. Hal ini tidak dapat ditemui di media massa yang hanya mampu mendiseminasi informasi satu arah. Kata kunci: Change.org Indonesia, demokrasi, analisis wacana, aspirasi
