Centrilobular Hemorrhagic Necrosis of the Liver in hemodynamically unstable patients
Authors: Силивончик Н.Н. , Штонда М.В. , Пристром М.С. , Воробьева Е.П. 
Published: January 2024

Центрилобулярный некроз клеток печени связывают с недостаточностью перфузии печени. Это повреждение печени обычно обозначается терминами «гипоксический гепатит», реже – «гипоксическое повреждение печени», «ишемический гепатит» или «шоковая печень». Гипоксический гепатит является наиболее распространенной причиной значительного, но преходящего повышения активности аминотрансфераз сыворотки в большинстве исследований. В настоящее время патогенез гипоксического гепатита не полностью ясен, но большинство исследователей согласны с тремя механизмами: печеночная ишемия, вызванная уменьшением притока крови к печени; венозный застой, вызванный правожелудочковой сердечной недостаточностью; артериальная гипоксемия, вызванная уменьшением кислорода в крови. Гипоксическое повреждение печени является частым и опасным для жизни осложнением у критических пациентов.
The centrilobular liver cell necrosis is attributed to failure of hepatic blood perfusion. This injury of the liver is commonly recognized under the terms "hypoxic hepatitis", less often "hypoxic liver injury", "ischemic hepatitis" or "shock liver". HH is the most common cause of a significant but transient elevation in serum aminotransferases activities in most studies. Currently, the pathogenesis of hypoxic hepatitis is not completely clear, but most researchers agree on three mechanisms: hepatic ischemia caused by decreased blood flow to the liver, venous congestion caused by right heart failure, and arterial hypoxemia caused by a decrease in oxygen in the blood. Hypoxic liver injury is a frequent and life- threatening complication that occurs in critically ill patients.

Drying is a common method applied to agricultural and plantation products to prevent the growth of bacteria and other microorganisms. This research aims to determine the optimum temperature and humidity of the heating air for coffee beans drying in a fluidized bed dryer (FBD) without the addition of adsorbents, to study the effectiveness of zeolite adsorbent as air dehumidifier in order to improve the drying process, and to determine energy consumption in the coffee drying process in an FBD. This research was conducted using 500 grams of Arabica coffee, air temperature variations of 400C, 500C and 600C with an average air velocity of 4.91 m/s. The addition of 1.08 kg of zeolite as an adsorbent was carried out to improve process performance and to reduce the drying time. Coffee bean quality was determined by moisture test using gravimetric method, protein test using Kjeldahl’s method and carbohydrate test using Luff-Schoorl’s method. The results showed that the optimum conditions for drying coffee beans to reduce the moisture content from 28% to 12.45% using an FBD without adsorbent were obtained at a drying air temperature of 500C with a drying time of 3 hours. Coffee bean drying assisted by Zeolite adsorbent was able to reduce the drying time by 11% with the most efficient energy consumption of 76,200 kJ/kg.

Published: January 2024

Double jacket mixing tanks offer temperature control and versatility for industrial processes where temperature-sensitive materials need to be mixed, stored, or processed. The selection of the appropriate jacket type in a double-jacket mixing tank is based on the structural strength and the optimal heat transfer performance. The type of jackets can be conventional, dimple, and half-pipe. The conventional jacket is easier to manufacture, but it is not resistant to high temperature and pressure. The dimple jacket has good heat transfer, but it is susceptible to damage. The half-pipe jacket has good structural strength, but its heat transfer is affected by the central angle and pipe diameter. 120° central angle has greater heat transfer and pressure drop than 180° central angle. In order to determine the effects of steam velocity on heat transfer performance, heating time, and pressure drop of the 120° half-pipe jacket, research occurred on pipes with 2, 2.5, and 3 inches of diameter. The calculating method of heat transfer in agitated jacketed vessels is applied to visualize the relationships. The effects of steam velocity on heat transfer, heating duration, and pressure drop respectively are polynomials of order 2, power, and polynomials of order 2 with an average R2 close to 1. The greater R2, the better the relationship between two variables, according to the equation. The 120° half-pipe jacket performance will be highly effective, with 1774 W, 2.1 minutes heating duration, 8.94 kPa pressure drop if the steam velocity is 10.50 m/s with 2.5 inches pipe diameter.

Authors: Borisov R. R. , Nikonova I. N. , Kovatcheva N. P. 
Published: January 2024

The aim of the work: to identify behavioral responses that make it possible to characterize the food attractiveness of potential feeding objects for juveniles of the crayfish Cherax quadricarinatus.Used methods: the study was conducted on the juvenile Australian red-clawed crayfish C. quadricarinatus, in the aquarium room of aquaculture invertebrate department at VNIRO. 11 types of feeding objects of plant and 4 types of animal origin were studied, as well as TetraWaferMix compound feed as a control. A total of 616 experiments were performed.Newness: on the juveniles of the Australian red-clawed crayfish C. quadricarinatus, the methodology for assessing the nutritional attractiveness of feeding objects by the nature of behavior during feed consumption was tested.Result: the experiments conducted showed that a large proportion of individuals who threw, crumbled, held food with their oral limbs for a long time without attempting to mechanical processing it or did not eat the food, indicates its unsatisfactory nutritional qualities. The time spent by crayfish on eating food depends on the hardness of the proposed components, the rate of their softening in water, the size of individuals and therefore cannot directly characterize the nutritional attractiveness of the feed. Most of the proposed forage objects (11 out of 15) had attractive nutritional characteristics for juveniles of C. quadricarinatus crayfish. The most active juveniles consumed animal feed (larvae of Chironomus sp. and Hermetia illucens, squid meat, Gammarus sp.), and among the feeds of plant origin, the seeds of oats, wheat and fried buckwheat, as well as beets and potatoes had the greatest attractiveness.

Published: January 2024

The aim of the study was to develop therapeutic measures to combat bacterial hemorrhagic septicemia of fish using a complex of antibacterial drugs “Levofloxacin” and “Chlortetracycline”.Methods used: experiments were carried out in aquarium conditions on juvenile carp and hybrids «Siberian sturgeon×Kaluga» (hereinafter hybrid SO×K) infected with a mixed culture of pathogens: highly pathogenic strains of Aeromonas sp., strains of R.R. Acinetobacter and Citrobacter. In the experiment, 2 variants of the use of antibiotics for a course of 7 days were tested. Bacteriological seeding of fish parenchymal organ samples was carried out on nutrient and differential diagnostic media.Novelty: it consists in working out the scheme of application for fish of a complex of new antibiotics for aquaculture.Results: the results of the evaluation of the therapeutic effect of antibiotics “Levofloxacin” + “Chlortetracycline” in the treatment of bacterial hemorrhagic septicemia are presented. The cessation of fish death was noted the next day after the start of therapy. Positive results were obtained in carp — with a combination of levofloxacin at a dosage of 1000 mg/kg of ichthyomass and chlortetracycline — 100 mg/kg of ichthyomass, in a hybrid of SO×K — 500 mg/kg of ichthyomass of levofloxacin + 200 mg/kg of ichthyomass of chlortetracycline. Evaluation of their combinations with different dosages did not show 100% effect. The difficulties of therapy have been identified, which are associated with the spread of strains of microorganisms resistant to antibacterial drugs.Practical significance: the developed method of therapy is effective, reduces the damage from the disease and can be recommended when developing measures to combat bacterial hemorrhagic septicemia in fish in aquaculture.

Published: January 2024

The purpose of the work: to estimate fish breeding indicators of three hybrid forms of whitefish in comparison with parental species when grown in cage aquaculture.Methods used: the production and cultivation of hybrids and parental species were carried out using standard technology for whitefish from November 2021 to May 2022. We have studied the survival and growth rate of fingerlings, and we also conducted a comparative assessment of the exterior of yearlings using factor and cluster analyses.Novelty: for the first time, three hybrid forms of peled and parent species (peled, muksun, broad whitefish, nelma) were grown in cages, and a comparative analysis of survival, growth and morphology of hybrids and parent species was performed.Results: all hybrid forms occupy an intermediate position in terms of growth rate, surpassing the maternal species (peled), yielding to the paternal ones. The best results in terms of weight and linear growth among hybrids were noted in pelchir. In terms of survival, oneyearlings of all hybrids show the effect of heterosis, although at the stage of larvae and early juveniles, the superiority in survival of hybrid forms over the parental pair was noted only in pelnelm. The survival rate of hybrid eggs, as well as the survival rate of pelchir and pelmuk at the early stages of cultivation, had intermediate values — lower than that of peled, but significantly higher than that of paternal species. The lowest survival rate of eggs among hybrids is shown in pelchir. The peled has the most significant morphological differences from other pure species and hybrid forms used in the experiment, all hybrid forms show more similarity with the paternal species.Practical significance: results provide a potential assessment of whitefish hybrids for the prospect of their use in commercial aquaculture.

Published: January 2024

This study aims to identify the total mercury content in the muscle and hepatopancreas of the main commercial crustaceans from the Barents Sea.The material for this study was the samples of red king crab Paralithodes camtschaticus and northern shrimp Pandalus borealis caught during the research cruises conducted by “PINRO” from 2012 to 2022. This study examines the samples of muscle collected from crustaceans, as well as the samples of hepatopancreas collected from the red king crab.Novelty: This study involves abundant data that was used to make the first comparative analysis of the Hg concentration in red king crab and northern shrimp. A significant similarity in the levels of Hg content in the muscle of shrimp and crab at the mean level was shown. The paper provides maps of average Hg content in the studied species for the entire Barents Sea.Methods used: the total mercury content in the samples was estimated by flameless atomic absorption spectroscopy analysis using Shimadzu Cold Vapor Atomic Absorption Spectrophotometer (Japan). Statistical data processing and charting were done using MS Excel and application software package of Statistica 13.Results: The paper shows that the average concentration of Hg in the muscle and hepatopancreas of the studied hydrobionts did not exceed 0.2 mg/kg of wet weight that is the acceptable concentration established by sanitary standards. The content of Hg in the red king crab’ hepatopancreas was about 2 times higher than in the muscle. The paper makes an assumption on the species-specifity of Hg content in the red king crab’ muscle. The Hg content in the muscle of P. borealis is strongly related to its fattiness. The paper suggests calculated background levels of the total Hg concentration in the muscle of P. camtschaticus and P. borealis from the Barents Sea.Practical relevance: The results obtained were used to establish the safety compliance of commercial crustaceans with the requirements adopted in Russia.

Published: January 2024

The purpose: to obtain modern data on the distribution, abundance, size composition and biological state of the sturgeon in the middle reaches of the Lena River.Material: data of scientific accounting survey using bottom drift nets in summer 2022.The results: Siberien sturgeon is dstributed irregularly on a 400‑kilometer stretch of the river from the city of Yakutsk to the Vilyui River, with the highest average density near the Vilyui River mouth 163 ind./km2, while sturgeon densities in the areas of Yakutsk and the Aldan River mouth were 71 and 44 ind./km2 respectively. The highest density of fish with the smallest average size in the area near the Vilyui mouth indirectly indicates the presence of a separate herd in the Vilyui River. The average density of fish over the entire 400‑km area was 93 ind./km2. The sturgeon length to the end of the middle rays (ac) was from 21 to 86 cm; on average 43.4 ± 10.7 cm. The modal size class for the sturgeon in catches in 2022 was 41–50 cm (44% of the total catch). The fish weight ranged from 40 to 3800 g. The average weight of individuals was 0.557. More than 80% of fish from all catches weighed up to 700 g. The weight of fish with a length ac 62–71 cm ranged from 0,400 to 1.415 kg, on average 1.0 kg. There were only 2.5% of commercial individuals in the total harvest. Sexually mature females were noted only near the Aldan mouth, where their share was 11% that may indicate the presence of spawning grounds in its channel. In the sample of fish that underwent a complete biological analysis (one third of the catches), sexually mature males were not observed. Estimated number of sturgeon: in Yakutsk city area — 17000 ind., in the Aldan mouth area — 47000 ind., in the Vilyui mouth area — 55000 ind. The total number of Siberian sturgeon on a 400‑kilometer stretch of the Lena River was at least 120000 ind. The state and structure of sturgeon population corresponds to the average statistical retrospective data.Practical value: the results obtained will improve the efficiency of assessing the distribution and stock of sturgeon in the Lena River.

Authors: Listyaningrum Trisna Avi , Toifur Moh. 
Published: January 2024

Penggunaan pupuk anorganik akan memberikan suhu yang lebih panas daripada menggunakan pupuk organik. Hal ini disebabkan oleh kandungan hara yang ada di pupuk anorganik lebih tinggi dibandingkan dengan kandungan hara di pupuk organik. Tinggi rendahnya suhu tanah akan berpengaruh pada pertumbuhan tanaman, semakin tinggi suhu tanah maka akan semakin cepat pertumbuhan pada tanaman. Penelitiaan ini bertujuan untuk menganalisis hasil perkembangan tanaman kangkung yang ditanam dengan menggunakan pupuk organik cair COSIWA dan pupuk anorganik cair NPK. Desain penelitian ini adalah pengukuran suhu tanah dan juga ketinggian tanaman berdasarkan kedalaman tanah pada tanah berpupuk organik menggunakan COSIWA dan pupuk anorganik menggunakan NPK cair. Data yang dihasilkan berupa pengukuran suhu tanah selama 12 jam, dan pengamatan panjang batang tanaman, warna dauh, kondisi batang, kondisi kesegaran tanaman selama 4 minggu. Hasil dari penelitian ini adalah Tanaman kangkung yang ditanam dengan menggunakan pupuk organik cair COSIWA memiliki suhu tanah yang lebih rendah yaitu 32,2 oC dibandingkan dengan tanaman kangkung yang ditanam dengan menggunakan pupuk anorganik cair NPK yaitu 32,2 oC. Selain itu pertumbuhan tanaman kangkung yang ditanam dengan menggunakan pupuk organik cair COSIWA maupun tanaman kangkung yang ditanam dengan menggunakan pupuk anorganik cair NPK menunjukkan hasil pertumbuhan yang hampir sama dilihat dari hasil pengamatan pada panjang tanaman, kondisi daun, kondisi batang, dan dari kesegaran tanaman.
