Tissue Regeneration in Infected Wounds of Albino Rats Using Ciprofloxacin-Loaded Gelatin Microspheres Incorporated Collagen Scaffold: A Histological Approach with H&E Staining
Authors: Shanmugam Kirubanandan
Published: June 2024

A wound care system consisting of ciprofloxacin-loaded gelatin microspheres impregnated in a macroporous collagen scaffold was created to effectively control wound infection and regenerate soft tissue at the wound site. Histological and biochemical alterations were observed in infected wounds treated with these scaffolds in Albino Wistar rats. Furthermore, the study examined the immediate and prolonged release of ciprofloxacin from the scaffolds, as well as their function in eliminating bacterial infections and expediting the process of skin healing and regeneration. The developed technique was followed in the streamlined process of creating these collagen scaffolds. Compared to untreated wounds, the group receiving scaffold treatment experienced a faster rate of wound closure. It was noted that the rate of infections was considerably reduced and that full soft tissue regeneration occurred within 12 days. The development of well-deposited collagen bundles in the treated groups was demonstrated by H&E staining, which verified the flawless regeneration of the dermis and epidermis. The antimicrobial agent-loaded gelatin microspheres impregnated into the porous collagen scaffold demonstrated remarkable soft tissue regeneration and efficient infection control at the wound site.

Authors: Fu Xubo
Published: June 2024

Objective: To analyze the clinical effect of high-dose citrate in segmental extracorporeal anticoagulation for high-throughput hemodialysis. Methods: The subjects included in this study were admitted to the hospital for maintenance hemodialysis treatment from January 2021 to January 2023. All patients had a high risk of bleeding and received 4% trisodium citrate anticoagulant treatment, administered at a rate of 200 mL/h before and after the dialyzer. The anticoagulant effects achieved by the patients were observed and analyzed. Results: The total number of patients who received high-dose segmented citrate extracorporeal anticoagulation dialysis treatment was 50, with each patient undergoing 100 treatments. During the treatment, 2 patients had to end the treatment early due to transmembrane pressure exceeding 30 mmHg and an increase in venous pressure exceeding 250 mmHg; the treatment times for these patients were 20 minutes and 200 minutes, respectively. The remaining patients successfully completed the 4-hour treatment. Blood pH and calcium ion concentration in the venous pot were monitored. It was observed that before dialysis, after 2 hours of dialysis, and at the end of dialysis, the blood pH of the patients remained within a relatively normal range. Although some patient levels changed after dialysis, they remained within the normal range. No adverse reactions (such as numbness of the limbs or convulsions) were observed during the anticoagulant treatment. Conclusion: Administering 4% trisodium citrate at a rate of 200 mL/h before and after the dialyzer achieves a good anticoagulant effect, maintains the patient’s blood gas levels within the normal range at the end of dialysis, and causes no adverse reactions.

Authors: Chen Xiaomin , Dai Narisu
Published: June 2024

Objective: To systematically evaluate the safety and efficacy of Mongolian medical warm acupuncture in the treatment of lumbar disc herniation (LDH). Methods: CNKI, Wanfang, VIP, Pubmed, Embase, Cochrane Library, and other databases were searched. The randomized controlled trials (RCTs) on the treatment of LDH with Mongolian medical warm acupuncture were manually searched in the Chinese Journal of Ethnic Medicine, Chinese Journal of Mongolian Medicine, Journal of Inner Mongolia University for Nationalities, and Journal of Inner Mongolia Medical University. The search time limit was from January 2000 to October 2023. RevMan5.4 software was used to analyze the included and excluded literature. Results: A total of 8 RCTs involving 1,042 patients with LDH were included, with 551 patients in the observation group and 491 patients in the control group. The results of the meta-analysis showed that a total of 8 randomized controlled trials were included in the treatment of LDH with Mongolian medical warm acupuncture compared with simple acupuncture (RR = 1.18, 95% CI = [1.12, 1.23], P < 0.00001). Conclusion: The total effective rate of Mongolian medical warm acupuncture for LDH is higher than that of simple acupuncture. However, due to the low quality of the literature included in this study, multi-dimensional, large sample size, and more rigorous clinical randomized trials are needed for further verification in the future.

Authors: Grubnik V. V. , Ilyashenko V. V. , Zagrebelna-Karayani K. V. , Parfentiev R. S.
Published: June 2024

Objective. To improve the technique of laparoscopic choledocholithotomy to improve the results of choledocholithiasis treatment.
Materials and methods. The study covers the period from 2012 to 2022, during which 144 patients with choledocholithiasis were treated. In 120 patients, the surgical intervention was successfully performed using a fully laparoscopic approach: in 48 patients (group 1), the common bile duct was drained with a T-shaped drainage; in 34 patients (group 2), the intervention on the common bile duct was completed with a primary suture of the duct; in 38 patients (group 3), a biliary stent was inserted integrally with subsequent suturing of the choledochotomy opening.
Results. In group 1, 5 (10.4%) patients had serious complications that required repeated surgical interventions: dislocation of the T-shaped drainage in 1 (2.1%) patient, development of biliary peritonitis in 4 (8.3%) patients. In the treatment of patients in group 2, a number of advantages were noted compared to the treatment of patients with T-shaped drains. The majority of patients with primary common bile duct suture were discharged on the 3rd day after surgery, and they returned to active work in 2 to 3 weeks. At the same time, 3 (8.8%) patients in this group had complications that required repeated surgical interventions: in 1 patient with multiple choledocholithiasis, bile leakage into the abdominal cavity was caused by a residual stone, in 2 patients - by papillitis and partial inflammatory stenosis of the large duodenal papilla. They underwent endoscopic papillotomy. Of the 38 patients in group 3, 32 had biliary stents that migrated to the intestine on their own. These patients had no complaints in the long term. In 6 patients, the stents remained in the ducts for 30 days after surgery. In 5 of them, endoscopic dosed papillotomy with a needle papillotome was performed, after which the stents were easily removed from the ducts. In 1 patient, a stone up to 6 mm in diameter fell out of the common bile duct along with the stent. None of the patients had signs of pancreatitis or elevated blood amylase levels.
Conclusions. Laparoscopic interventions on the common bile duct allow successful removal of large and numerous calculi in one stage. Primary suturing of the common bile duct has significant advantages over the installation of T-shaped drains and allows to reduce the treatment time. In case of multiple choledocholithiasis and suspected stenosis of the duodenal papilla, it is advisable to combine primary common bile duct suture with antegrade stenting of the bile ducts.

Published: June 2024

Anthracnose of beans caused by Colletotrichum lindemuthianum is regarded as one of the most damaging diseases of legumes, producing major losses in productivity and quality every year. Several fungicides are available for control but are dangerous to the health of the environment and organisms, so developing organic solutions is imperative. The in-vitro study includes five botanicals namely neem, mugwort, garlic, ginger, and wild sage, to evaluate their capacity to inhibit the mycelial growth of C. lindemuthianum. Analysis was done with the poisoned food technique with four replications for each botanical used in a completely randomized design (CRD). The maximum growth inhibition (100%) was observed in garlic at 10% concentration, followed by ginger (81.15%), while the minimum growth inhibition (36.58%) was observed in wild sage at 10% concentration. Garlic, neem, and mugwort exhibited greater efficiency at lower concentrations, whereas ginger and wild sage demonstrated increased efficiency with higher concentrations. The in-vitro study needs to be tested in field conditions to determine the practical efficiency of the botanicals, and a focus should be made on using garlic and ginger to find organic solutions against the anthracnose of beans.

Rice is the fundamental staple crop of Nepal. For food security, the production rate of main season rice is insufficient; nevertheless, spring rice can be a possibility. Spring rice is short duration crop as compared to the main season crop as, it can be best utilized through its cultivation. An experiment on spring rice (Oryza sativa) was performed to examine ten different elite rice genotypes in irrigated seedling stage at Campus of Live Sciences, Tulsipur, Dang from April to May 2023 with an objective to assess the response of different genotypes of seedling stage under controlled environment condition and to compare seedling stage growth and development of different spring rice variety The study was conducted with three replications on a completely randomized design (CRD). Data on the seedlings' growth was gathered at intervals of ten days. The outcome showed that there were statistical differences in morphological features between various genotypes. In comparison to other plants, IR09R270 had the highest average plant height (12.9 cm), IR17A106 had the greatest amount of leaves (2.44), IR09R270 had the greatest length of leaves (6.59 cm), Svin080 had the widest leaves (0.18 cm), IR112208B-B-RGA-BRGA had the longest shoots length (16.46 cm), and IR112208B-B-RGA-BRGA had the longest roots length (9.30 cm). The sample with the highest percentage of germination (85.65%) was IR112208B-B-RGA-BRGA. The majority of genotypes were found to have heritability more than 60%, indicating a greater contribution from genetic factors than environmental conditions. It was discovered that the phenotypic coefficient of variance (PCV) was marginally larger than the genotypic coefficient of variance (GCV), suggesting that the environment had little effect on how characters are expressed. The study's conclusions demonstrated that the rice genotypes IR09R270 and IR112208B-B-RGA-BRGA were preferable to other elite genotypes found in the Terai region. In conclusion under irrigated conditions, rice genotypes IR09R270 and IR112208B-B-RGA-BRGA performed well.

A field research was carried out at the National Wheat Research Program (NWRP) in Bhairahawa, Nepal in 2022 to investigate elite durum wheat genotypes and key traits contributing to grain yield. The experiment was performed in an alpha lattice design with two replications. Thirty distinct durum wheat genotypes were assessed, focusing on fourteen quantitative traits including days to booting, days to heading, days to maturity, plant height, spike length, peduncle length, number of tillers per square meter, number of spikes per square meter, number of grains per spike, grain weight per spike, thousand kernel weight, grain yield, biomass yield, chlorophyll content. The studied genotypes were grown under irrigated condition. Genotype NL1779 attained the highest grain yield of 3828 kg/ha, followed by NL1769 (3784 kg/ha), NL1772 (3726 kg/ha), NL1789 (3640 kg/ha) and NL1784 (3570 kg/ha). Principal components analysis revealed that eight traits were the major loadings on the first two principal components that describe 53.4% of the total morphological variance at irrigated condition. Cluster analysis grouped the different genotypes into four clusters, with each cluster showing variation in performance for different traits under irrigated conditions. Cluster III is characterized by genotypes exhibiting the highest grain yield, biomass yield, spike length, number of grains per spike, and number of spikes per square meter. Notably, the high-yielding genotypes NL1779, NL1769, NL1772, NL1789, NL1784, and NL1773 identified within this cluster could serve as potential candidates for inclusion in the national breeding program. These superior genotypes could be recommended for irrigated environment after further evaluation. Integrating them into national breeding programs offers an opportunity for genetic improvement, contributing to establishing a robust durum wheat production system in Nepal, meeting the growing demand for durum wheat products while promoting dietary diversity and sustainable agriculture.

Published: June 2024

This study examined the fish fauna of Chinadi Beel in Bangladesh in terms of diversity, quantity, and state of conservation. A pre-tested questionnaire and a direct catch evaluation survey were employed to conduct the study in the beel. In the examined beel, a comprehensive count of 3,360 fish specimens, encompassing 52 distinct fish species from 8 orders and 19 families, was documented. Cypriniformes was identified as the dominating order among the 8 orders examined, accounting for 51.49% of the total. Out of 52 fish species about 31 least concern (59.61%), 8 endangered (15.38%), 6 vulnerable (11.54%), 6 near threatened (11.54%) and 1 critically endangered (1.92%) species were observed according to the International Union for Conservation of Nature. The study utilized population diversity indices, specifically the Shannon-Weiner diversity index (H'), Margalef species richness (d), Pielou's evenness index (J'), and Simpson dominance index (c), to assess the species diversity, richness, and evenness of fish which value were found to be 2.50, 4.30, 0.90, and 0.30, respectively. Chinadi Beel has the capacity to function as a significant reservoir of fishing resources and a repository of genetic information for many fish species. However, the present study emphasized several anthropogenic and environmental issues, such as unregulated fishing, agricultural pollutants, illegal or harmful fishing, the construction of infrastructure for development, and climate change. Hence, it is highly recommended to implement ecosystem-based fisheries management that actively involves the local population in order to guarantee the long-term preservation of these water bodies.

Several human activities have led to environmental pollution with crude oil and other related hydrocarbons. There are various technologies of remediating oil-polluted environments, but the use of biological agents such as biosurfactants are widely practiced, and are generally considered as safe and eco-friendly. This study aimed at isolating and identifying biosurfactant-producing bacteria obtained from oil polluted soil samples in Abakaliki, Ebonyi State, Nigeria using molecular techniques. Six waste oil-contaminated soil samples were collected from mechanic and generator repair workshops, and were analyzed using standard microbiological methods. Nine bacterial isolates were obtained from the waste oil-contaminated soil samples, and were suspected to be Pseudomonas aeruginosa, Bacillus subtilis and Staphylococcus aureus. Molecular identification of the biosurfactant-producing isolates was also carried out using PCR and the genes responsible for biosurfactant production targeted. Oil spreading technique was used to detect the oil displacement activity (ODA) of the isolates. The emulsification index (E24) was calculated and the ability of the extracted biosurfactant to emulsify the hydrocarbons was determined. Pseudomonas aeruginosa had the highest ODA of 28.1 cm while Staphylococcus aureus had the least ODA of 5 cm. Pseudomonas aeruginosa showed E24 of 70.1%, Bacillus subtilis 57.1% while S. aureus showed 32.5%. Hence, Pseudomonas and Bacillus species have good potentials for biosurfactant production, and can be harnessed and utilized in the cleanup of oil polluted soil.

Quantitative data on the effects of essential micronutrients—boron, zinc, and copper—on rice (Oryza sativa L.) are limited, which hampers optimized crop management strategies. This study aimed to enhance rice yields through the foliar application of these micronutrients. Conducted in 2022 at Gokuleshwor Agriculture and Animal Science College using a randomized complete block design with three replications, the research tested different combinations of these elements on the local rice variety Kaljade. The treatments included: T1 (control), T2 (zinc), T3 (copper), T4 (boron), T5 (Zn + Cu + B), T6 (Zn + Cu), and T7 (Zn + B), with doses of 5 kg/ha for zinc and 2 kg/ha each for boron and copper. The results demonstrated significant effects of the micronutrient treatments on all parameters studied. Notably, the combination of zinc, copper, and boron (Zn + Cu + B) led to the most favorable outcomes. This treatment resulted in the shortest maturity duration (116.3 days after transplanting), the highest number of tillers (22.5), and the tallest plant height (107.7 cm). Additionally, Zn + Cu + B produced the greatest leaf area index (0.0724), the highest number of grains per panicle (22.6), and the heaviest thousand-grain weight (21.83 g). Furthermore, Zn + Cu + B achieved the highest biological yield (12.35 t/ha) and grain yield (5.9 t/ha), markedly higher than the control treatment (4.12 t/ha). These findings highlight the significant role of zinc, copper, and boron in rice cultivation. The study underscores the potential of foliar application techniques to optimize micronutrient availability, thereby enhancing rice yields. For future agricultural practices in the study area, focusing on zinc, copper, and boron nutrition is crucial to further augment crop productivity and ensure food security.

Published: June 2024

The results of the study of enzymatic activity of peats of the three bogs of upper and lowland types – Saim, Bolshoye and Tungusovskoye (Tomsk region) are presented. The peculiarities of organic matter formation of peats of different types are given. It is shown that the properties of peats with up to eight different plants in their composition are a consequence of the different structure of polymers of the original plants. The activity indices of enzymes invertase, protease, catalase, polyphenol oxidase, nitrate and nitrite reductase in the peats of different genesis are determined. Thus, at the type level, the extreme values of nitrate and nitrite reductase activity in the peats of the upland bog are equal to 3.60–4.94 mg of reduced NO3– /24 h/g and 3.52–7.01 mg of reduced NO2–/24 h/g, respectively, lowland bog – 4.66–19.33 mg of reduced NO3–/24 h/g and 0.9–13.0 mg of reduced NO2 –/24 h/g, fluvial bog – 8.77–22.29 mg of reduced NO3–/24 h/g and 0.2–13.6 mg of reduced NO2 –/24 h/g. The activity of the enzyme in peats and in mineral soils is compared with the activity estimation according to the D.G. Zvyagintsev scale. Peats are found to show a wider range of invertase values than indicated by the scale. The need to develop a gradation of enzymatic activity assessment for peats is identified. Probably, the activity of enzymes on peat OM transformation may increase when external conditions change towards warming. In the future, it is suggested to develop an evaluation cadastre of peats by enzymatic activity, which will allow, through a balanced selection of peats for agricultural production, to ensure the required quality of products, their environmental safety and economic efficiency.

The vibration method of feed grain crusher can be realized in various designs of crushers, but preference should be given to dynamic machine schemes, as such systems contribute to energy saving and increase the reliability of the whole structure. The analysis of the totality of information on vibrating crushers developed in various branches of economy allowed formulating the main requirements to the dynamic systems of these machines. These include the following: providing vibration of points of the working bodies according to certain laws; implementation of self-synchronization of vibro-exciters (in the case of a pair of vibro-drive); ensuring the minimum amplitude of the load-bearing system of the crusher, on which the vibro-exciters are mounted; ensuring the maximum amplitude of the working body of the crusher; compactness of the vibro-drive; absence of parasitic vibrations. Due to these requirements, vibrating jaw crushers for feed grain deserve special attention. Crushers close in technical essence are successfully used in mining. In such crushers, various vibratory dynamic effects important for the technology are manifested. The purpose of this work is to increase the technical level of the vibrating crusher of feed grain on the basis of using the effects of self-synchronization of vibration exciters and intensification of discharging the crushed material. The mathematical model of dynamics of the vibrating jaw crusher of feed grain, taking into account its design features and interaction of working bodies with the technological medium, is obtained. It is found that of the two possible synchronization modes, the synchronous-synphase mode is stable. Analytical analysis has shown the technological operability of the dynamic scheme of the vibrating jaw crusher in this synchronization mode, while the dynamics of the crusher meets almost all other specified requirements.

Perilla frutescens is a monotypic genus of annual herbaceous plants of dead nettles. The article presents a simultaneous evaluation of the presence of both phenolic compounds in P. frutescens seed extracts and compounds of other chemical classes. It has been confirmed that the seeds of P. frutescens varieties k-130, k-263, k-326 contain a large number of polyphenolic complexes, which are biologically active compounds. The complete metabolomic composition of perilla seed extracts is presented for the first time. The study utilized a tandem mass spectrometry method involving the use of liquid chromatography in parallel with an ion trap. Using tandem mass spectrometry, the presence of 60 compounds was identified, of which 41 compounds represent the group of polyphenolic compounds, as well as 19 compounds of other chemical groups in perilla extracts. The chemical components were identified by comparing their retention index, mass spectra and MS fragmentation with the home library database based on the data from other spectroscopic techniques such as nuclear magnetic resonance, UV-visible spectroscopy and mass spectrometry. Also, 29 chemical compounds were found for the first time, including 16 compounds of polyphenolic group and 13 compounds of other chemical groups. Lignans: syringaresinol and medioresinol; coumarins: umbelliferone and 4-hydroxycoumarin; flavones: luteolin 7-O-glucoside, diosmetin C-hexoside, chrysoeriol C-hexoside C-pentoside; flavanols: ampelopsin, astragalin, etc. were identified in perilla seeds for the first time. The data obtained will help intensify future research on the development and production of new drugs, dietary supplements and various functional, specialized and dietary products containing targeted perilla extracts.

Authors: Andreeva O. T.
Published: June 2024

The article presents the results of the study of the influence of sowing dates on the productivity of less common agricultural fodder crops: fodder millet, Sudan grass, spring triticale, Scarlet amaranth and fodder beans. The studies were carried out at the experimental field of the Research Institute of Veterinary Medicine of Eastern Siberia located in the forest-steppe zone of Transbaikalia. The soil of the site is meadow-chernozem mealy-carbonate, light loam by granulometric composition. The studied crops were sown at different dates to determine the degree of influence of the sowing dates on the duration of interphase periods of plant development, their linear growth, foliage and productivity: May 15 and 25, June 15 and 25. The obtained data indicate that by changing the sowing dates it is possible to influence the productivity of the studied crops and the quality of forages made on their basis. The best indicators on fodder productivity and nutritive value were demonstrated by the crops sown on June 15: yield of green mass – 18.9–30.5 t/ha, dry matter – 3.93–5.70 t/ha, yield of fodder units – 3.03–4.67 t/ha, digestible protein content – 306–901 kg/ha, gross energy – 38.12–57.57 GJ/ha, provision of 1 fodder unit with digestible protein – 93–193 g. Crops of fodder beans and Scarlet amaranth had an advantage, characterized by the following indicators: yield of green mass – 29.6–30.5 t/ha, dry matter yield – 5.70–5.95 t/ha, yield of fodder units – 4.20–4.67 t/ha, digestible protein content – 722–901 kg/ha, gross energy – 52.86–57.57 GJ/ha, provision of 1 fodder unit of digestible protein – 172–193 g. Agrocenoses of Poaceae crops (spring triticale, fodder millet, Sudan grass) were inferior in productivity: their green mass yield was 14.4 –18.9 t/ha, dry matter yield – 2.97–3.93 t/ha, yield of fodder units – 2.23–3.03 t/ha, digestible protein content – 207–341 kg/ha, gross energy – 28.51–38.12 GJ/ha, provision of 1 fodder unit with digestible protein – 93–121 g.
