Published: July 2024

The article shows a clinical case of an extremely rare complication after laparoscopic cholecystectomy — a giant subcapsular hematoma of the liver. The clinical, laboratory and instrumental data of the patient and the results obtained were analyzed. Analysis of the data from the operated patient did not reveal the main reason that could have caused the development of a giant subcapsular hematoma of the liver. The patient had no bleeding disorders, had not previously suffered any bleeding, and did not take anticoagulants as an outpatient. During the operations, no source of bleeding or damage to the liver parenchyma was identified. In addition, there was no evidence of focal liver lesions according to the preoperative ultrasound scan. Outpatient use of a drug from the group of antiplatelet agents, as well as short-term irregular use of analgesics to relieve periodic pain could provoke the development of this complication. Treatment of subcapsular hematoma of the liver mainly depends on the clinical condition of the patient and the size of the hematoma. With conservative management, the condition of the formed hematoma should be more carefully monitored over time using radiation diagnostic methods. If necessary and according to indications, do not exclude possible repeated laparoscopic intervention, including conversion to laparotomy, taking into account the data of clinical, laboratory and radiological research methods. In most cases, this condition requires conservative treatment. Patients with such a complication require careful hemodynamic monitoring and visual monitoring of the complications development. Probably, preference should be given to magnetic resonance imaging, since this method is the most objective and does not carry a radiation load. The main task is not to miss the moment of hematoma rupture and the development of fatal bleeding.

Published: July 2024

The accumulation of mucus resulting from the obstruction of bronchi of cystic fibrosis (CF) patients, induces a reduction of the oxygen (O2) pressure and produces a hypoxic environment for the epithelial cells of the lungs. Our study aims to better characterize the impact of hypoxia on CFTR function in the pathophysiological context of cystic fibrosis. We used Human airway epithelial cells from two CF donors and human bronchial epithelial cell lines non-CF and CF, grown and expended in normoxia (21% O2) and then switched to hypoxia (1% O2) for 2 to 24 hours. Cells were treated by dimethyl sulfoxide or Elexacaftor/ Tezacaftor/Ivacaftor for 24 hours. We show that the peak of Hypoxia Inducible Factor 1α is reached in a range of 4 to 6 hours post-hypoxia induction. We also demonstrate that the global amount of ETI corrected F508del-CFTR is significantly decreased after 24 hours of hypoxia. A decreased ETI corrected F508del-CFTR activity was recorded by both patch-clamp and Ussing chamber recordings. Our results show that hypoxia, despite the effectiveness of Elexacaftor/ Tezacaftor/Ivacaftor correction, impacts the downstream effects of the F508del mutation, which suggests that oxygen availability in the lungs is a factor to take into account for the administration of Trikafta to patients.
La Chine fantasmée au XXIème siècle. Le cas des maîtres de taiji quan
Authors: Dreyer Serge
Published: July 2024

La pratique du taiji quan dans l’un de ses aspects martiaux, le pousser des mains (tuishou en chinois), relativement peu répandu en Europe est très souvent prétexte à la diffusion de discours emphatiques qui s’inscrivent dans le soft power chinois. On montrera dans cet article un fort décalage entre le milieu rural d’origine du taiji quan et sa récupération à partir du 19ème siècle par les lettrés chinois. Les discours théoriques prenant le pas sur la pratique définissent déjà à l’époque un maître imaginaire formaté par le contexte de la crise existentielle que traverse la Chine aux 19ème et 20ème siècle. Lors de la diffusion du taiji quan en Occident à partir des années 60, ces discours fantasmatiques vont être repris par le petit monde des sinologues. On observe avec intérêt des cultures de recherche différentes entre le monde anglo-saxon plutôt pragmatique et l’engouement d’une partie des intellectuels francophones porté sur la théorisation du domaine, en particulier son association très controversée avec le taoïsme, le chamanisme ou bien l’alchimie interne. Dans une dernière partie, on s’efforcera de montrer que le grand public des pratiquants agit comme une caisse de résonnance de ces discours fantasmés au point d’ignorer l’origine martiale du taiji quan pour en faire une discipline associée essentiellement au bien-être, à l’épanouissement spirituel. Quoi que puissent signifier ces termes au niveau individuel, on constate l’émergence d’un discours de type religieux ayant pour support une représentation culturellement hybride du corps. Le maître chinois en est devenu l’épitome.

Authors: Ginting Delovita , Azizah Nur
Published: July 2024

Termites are commonly seen as a nuisance due to their capacity to cause harm to wooden objects. The occurrence of termite infestations on furniture has led to a rise in financial damages attributed to such attacks. Hence, it is of utmost need to seek alternative raw materials that exhibit resistance to termite-induced deterioration, thereby fulfilling the requirement for substituting particle board. The present study has successfully demonstrated the fabrication of particle board by including bintaro fruit seed filler and urea formaldehyde matrix. The primary objective of this research endeavor was to explore an alternate approach to standard particle board production, specifically focusing on the development of anti-termite qualities. The filler fraction to matrix fraction comparison exhibits variations of 50:50, 60:40, 70:30, and 80:20. The particle board production process employed in this study utilizes a cold pressing method, wherein a pressure of 15 MPa is applied for a duration of 120 minutes. The board particles that have been acquired are subjected to testing in order to ascertain their physical characteristics, such as density and water content. The experiment was conducted in compliance with the SNI Standard 03-2105-2006. The flexural strength of particle board was evaluated in accordance with the standard SNI 03-2105-2006. An assessment was conducted to evaluate the susceptibility of particle board to termite infestation, in accordance with the guidelines outlined in the SNI 01-7207-2006 standards. The density and moisture content testing findings conducted on particle board match with the specifications outlined in the SNI 03-2105-2006 standard. The experimental outcomes evaluating the susceptibility of board particles to termite infestations have effectively fulfilled the requirements outlined in the SNI 01-7207-2006 standards.

Published: July 2024

Biodiesel has attracted attention as an alternative fuel in efforts to reduce emissions and dependence on fossil fuels. Among various potential sources for biodiesel production, jatropha and corn oil have stood out due to their availability and high yield potential. However, each has unique characteristics that affect their performance as fuels. Jatropha oil has relatively high viscosity, while corn oil is generally used as a food ingredient. This study aimed to explore the potential of combining jatropha and corn biodiesel in different proportions and its impact on fuel characteristics and diesel engine spray injection. Both types of oil were processed into biodiesel through esterification and transesterification processes. Subsequently, biodiesel mixtures were created in ratios of 1:4 and 4:1. Each mixture was then varied with diesel to produce B5, B10, B15, B20, B25, B30, B35, and B40. Each sample was tested for its physical properties such as density and viscosity, and injection spray angle. The results of this study indicated that the density and viscosity values of the 1:4 jatropha-corn biodiesel mixture were lower than those of the 4:1 jatropha-corn biodiesel mixture. There was a significant relationship between viscosity and density with the injection angle. The higher the density and viscosity, the narrower the injection angle.

Electrolyte disruption in drug-resistant tuberculosis: Managing risks for improved treatment outcomes
Authors: Yadav Sankalp
Published: July 2024

This editorial sheds light on the critical issue of electrolyte imbalance in drug-resistant tuberculosis (TB), a significant challenge exacerbated by the prolonged and intensive treatment regimens required for multidrug-resistant (MDR) and extensively drug-resistant (XDR) TB strains. The use of second-line drugs, such as fluoroquinolones and aminoglycosides, necessary in these cases, often disrupts electrolyte homeostasis, leading to complications like hypokalemia and hypomagnesaemia. These disturbances can pose serious risks to patients, including cardiac arrhythmias and renal dysfunction. Beyond medication effects, TB itself induces systemic inflammation and metabolic alterations, further complicating electrolyte balance. Effective management necessitates vigilant monitoring of electrolyte levels throughout treatment, coupled with renal function assessments and nutritional support.

Published: July 2024

Association of viral infection with obstructive jaundice is well-known however frequency of cholangiotropic virus infection in pediatric choledochal cyst is not known.

IgG and IgM antibodies against Cytomegalo virus (CMV) and Epstein Barr virus (EBV) in 48 children with choledochal cysts and 26 controls were analysed using ELISA.

We found significantly higher anti-CMV IgG and IgM in patients (95.8% and 77.1%, respectively) compared to controls (73.1% and 42.3%) and a notable prevalence of anti-EBV antibodies among both groups (83.3% versus 65.4% IgG and 77.1% versus 46.1 for IgM in patients and controls respectively). Moreover, 79.2% of patients were positive for both anti-CMV and anti-EBV IgG, and 62.5% for both IgMs.

This pilot study suggests that infection with CMV, EBV, or both is frequently seen in pediatric patients with CDC. Molecular screening and follow-up in a larger cohort is therefore required for further validation.
Evaluation of impact of adherence to inhaled therapy and critical mistakes in inhalation technique on clinical outcomes in patients with obstructive airway diseases in India
Authors: Godse Ajay , Gurjar Rakesh , Rao Namrata , Gore Shivanjali , Vijay Ria
Published: July 2024

Adherence to inhaled therapy is more relevant in respiratory diseases because, to achieve therapeutic efficacy, it is necessary that the patient adhere to the recommended therapy as well as use their inhalers correctly with appropriate inhalation technique.

This was a prospective, observational study that included 126 patients >18 years of age of all genders, diagnosed with an obstructive airway disease, and prescribed inhaler medication. Adherence was assessed using the Test of Adherence to Inhalers (TAI) questionnaire, and inhaler device technique was assessed every 3 months. At the end of one year, outcome data like the number of exacerbations, the number of admissions, including critical-care admissions, the number of days of hospitalization, adverse events, and their associations were analyzed.

Poor adherence to inhaled therapy was found in 40.48% of patients, with the majority of patients (69.05%) having an unwitting or ignorant pattern of non- adherence. Out of 75 patients using MDI (Metered Dose Inhaler), 34.67% had critical mistakes in technique, and out of 51 patients using Rotahaler, 23.53% had critical mistakes in technique. There was no significant relationship between level of adherence and critical mistakes with gender, BMI category, or past history of smoking. Patients with poor adherence and those with critical mistakes in inhalation technique had poor health outcomes.

This study highlights the role of adherence and identifies barriers responsible for non-adherence to inhaled therapy. Identifying the behaviors responsible for non-adherence and counseling the patients on the correct inhalation technique can improve the health outcomes of chronic respiratory diseases.

Authors: Kale Preeti , Kuchu Bhargav , B S Jeevan , Mavi Sunny , Raj Jamalpur Karthik
Published: July 2024

Peri-implant health is paramount for the long-term success of dental implants. While bone regeneration techniques have been extensively studied and employed to ensure implant stability, the significance of soft tissue condition in this context is increasingly recognized. This review article explores the intricate interplay between soft tissue dynamics and bone regenerative procedures in the pursuit of optimal peri-implant health. Soft tissue condition around dental implants plays a multifaceted role in supporting long-term stability and functionality. Adequate soft tissue thickness, contour, and attachment are crucial for maintaining a healthy peri-implant environment and preventing complications such as peri-implantitis and mucosal recession. Furthermore, soft tissue quality influences the outcomes of bone regeneration procedures by affecting vascularization, wound healing, and tissue integration. Various strategies have been proposed to enhance soft tissue condition in conjunction with bone regenerative techniques. Through a comprehensive review of existing literature, this article aims to elucidate the pivotal role of soft tissue condition in bone regenerative procedures and its implications for long-term peri-implant health. Insights gained from this review will inform clinicians and researchers in devising effective strategies to enhance soft tissue quality and ensure the success and longevity of dental implant therapy.

Published: July 2024

: High frenal attachments are abnormalities corrected by surgical procedure called frenectomies. The scalpel technique is associated with pain, bleeding and postoperative discomfort. To overcome these shortcomings, in the recent times, diode lasers are gaining popularity due to less bleeding, pain during the procedure, healing outcome, and need for analgesics

: To compare the bleeding during the procedure and postoperative pain in patients requiring labial frenectomy using conventional scalpel and diode laser techniques.

Twenty patients with high labial frenum attachment requiring frenectomy were included in this study. Patients were randomly divided into Group A: scalpel group and Group B: diode laser group. Pain assessment using VAS, severity of intraoperative bleeding and number of analgesics used were recorded

: The analysis showed that VAS score for pain was significantly lower in the laser group as compared to the scalpel group Bleeding was mild in laser group, where as in scalpel group showed moderate or severe bleeding scores Post operative use of analgesics was more in scalpel group than laser group

Laser was found to be an effective alternate to scalpel in performing frenectomy procedures, more importantly it showed less bleeding, less pain perception and more patient acceptance during the procedure.

Authors: Mathamkuth Abdurasheed E. M Edakkod , N Raseena Beevi , RA Rafeek , Ramesh Roshni , Philip Sharon
Published: July 2024

Plasma cell gingivitis (PCG) is an uncommon benign gingival condition characterized by sharply defined erythematous and oedematous gingival lesions, often extending to the mucogingival junction. This hypersensitivity reaction presents as diffuse, papillary gingival inflammation, prone to bleeding upon minimal trauma. Histologically, PCG manifests as a dense infiltration of normal plasma cells within collagenous stroma, typically localized to the free and attached gingiva. The primary management approach involves identification and avoidance of the allergen source, alongside nonsurgical periodontal therapy. We report a 26-years-old female patient diagnosed clinically as plasma cell gingivitis and confirmed histologically. Surgical treatment along with pharmacological interventions resulted in complete resolution of symptoms. This case underscores the importance of comprehensive evaluation and tailored treatment approaches in managing plasma cell gingivitis.

Experimental analysis of instability and self-oscillations in an electrohydraulic servo drive
Authors: Petrov P. V. , Sunarchin R. A. , Mashkov M. A. , Krivosheev N. S.
Published: July 2024

The tendency to self-oscillations is one of the most important problems of closed-loop hydraulic systems. In actual systems losses occur, variation of the transmitted energy and the strength of the system structural elements are always limited. This is the reason why self-oscillations are most often present. The main purpose of the research is to reveal the mechanisms of instability and self-oscillations in an electro-hydraulic servo drive to make a numerical simulation of the drive characteristics. A servo drive has all the conditions for the generation of self-oscillations: the oscillatory element – the movable member of the drive and a column of elastic liquid, the source of energy. Regular oscillations in a drive are maintained due to the energy of compressed liquid, feedback, non-linear character of generated and absorbed energy etc. An experimental analysis of a servo system of the FESTO training simulator was carried out. The aim of the research was to accumulate materials for the development of mathematical models that would adequately represent the main properties of actual systems.

Modelling width of the spectral component of a gas-turbine engine gearbox output shaft speed
Authors: Sundukov A. E. , Shakhmatov E. V.
Published: July 2024

Gearbox is the most stressed component in an aircraft gas-turbine engine. This implies the need for finding ways to monitor its technical condition. Practice shows that the most efficient method is vibration-based diagnostics. However, this method requires the use of sophisticated measurement systems and highly skilled personnel. This paper shows that errors of gear coupling manufacture and assembly, characteristics of machine operating mode, design factors, frequency modulation of the carrier of the engine rotor speed in the stationary mode of its operation, and wear of teeth flanks determine the width of the spectral component of the gearbox output shaft speed. Using the results obtained from the developed model of the width of gear tooth spectral component, ratios for width of the spectral component of the signal of the “standard” tachometric speed sensor of the gearbox output shaft speed and the corresponding spectral component of its vibration were obtained. Models for repaired and newly manufactured gearboxes and gearboxes with tooth flank wear were proposed. This allowed the development of a number of new diagnostic indicators of a defect. Several examples of the use of these new diagnostic indicators are given for the gearbox of one of turbo-prop engines. The results obtained provide an opportunity to assess the gearbox technical condition in operation.

Published: July 2024

The article discusses a method for calculating, as a first approximation, the take-off weight of a light aircraft with a hybrid power plant based on piston and electric engines. A brief overview of organizations dealing with hybrid power plants is given. The influence of the degree of hybridization of the power plant on the take-off weight of the aircraft is shown. The degree of hybridization of a power plant is understood as a relative value characterizing the distribution of the total power of all engines installed on the aircraft between piston and electric engines. The main parameters necessary to determine the take-off weight of an aircraft to a first approximation are presented. The take-off weight of the aircraft is determined to a first approximation from the equation of its existence. Statistical data of aircraft with different types of power plants are provided on the basis of which calculations are carried out. As a first approximation, the relative mass of the hybrid power plant is determined by analyzing the statistical data of light aircraft with piston and electric engines, from which the corresponding graphs are constructed. After the calculations, conclusions were drawn about the optimal range of characteristics of a light aircraft with a hybrid power plant.

The productivity of common beans has fluctuated in the last 5 years. The decrease and increase in productivity occur due to decreased soil quality due to a lack of organic matter. Plant productivity with excessive use of inorganic fertilizers can reduce soil fertility. The solution to restoring microbial activity and soil fertility levels can be taken through a nature farming approach, namely by utilizing organic fertilizers derived from cow manure and additional plant growth-promoting rhizobacteria (PGPR) biological fertilizers. This research was conducted at a production site on Jalan Tidar, Jember, East Java, from January to March 2023. The design used was factorial RAK with 3 repetitions. The first factor was the dose of cow manure, which consists of 4 levels, namely 0, 10, 15, and 20 tons/ha. The second factor was the concentration of PGPR, which consists of 4 levels: 0, 10, 15, and 20 mL/L. The results do not show any interaction between cow manure and PGPR on all parameters. Cow manure has a noticeable effect on growth parameters and quantity. The best dose of cow manure and the highest protein content value was 20 tons/ha. The concentration of PGPR had only a noticeable effect on plant height and number of leaves. PGPR concentrations of 15 mL/L and 20 mL/L both give the best results and produce the highest antioxidant activity value at 15 mL/L.

Wilt disease caused by Fusarium oxysporum f. sp. Capsici can cause serious problems and reduce red chili yields, so controls are needed that can reduce the development of the pathogen. The purpose of this study was to determine the potential of Trichoderma sp. from the bamboo rhizosphere in Kedu District, Temanggung Regency, in inhibiting the growth of F. oxysporum f. sp. capsici in vitro and in vivo. Trichoderma sp. Was isolated from the rhizosphere of bamboo plants, and F. oxysporum f. sp. capsici was isolated from red chili plants with symptoms of fusarium wilt. Mushroom isolates were purified and identified based on the identification key book. An in vitro test using the double culture method and an in vivo test were conducted in a screen house by applying Trichoderma sp. to the stem of red chili plants. One isolate of Trichoderma sp. was obtained from the soil of the bamboo rhizosphere in the Kedu District, and Fusarium sp. isolates were obtained from the stems of red pepper plants. Based on in vitro antagonist tests, Trichoderma sp. Fungi were able to inhibit the growth of F. Oxysporum f. sp. capsici up to 82.50% at 7 HSI. Trichoderma sp. could inhibit pathogens through antibiotic inhibition mechanisms and competition of nutrients and space to grow. Trichoderma sp. inoculation followed by in vivo inoculation of pathogens on red chili plant stems showed an attack symptom intensity of 4.16% with an antagonistic performance of 75.03% 12 days after inoculation. Trichoderma sp. is effective as an alternative biological control agent for red chili plant disease caused by F. Oxysporum f. sp. capsici.

Haemonchosis is an infection caused by the Haemonchus contortus worm, a blood-sucking gastrointestinal parasite that can also infect humans. Orthosiphon aristatus (Blume) Miq leaves have been shown to have anthelmintic activity due to the presence of saponins, flavonoids, and tannins. This study aimed to determine the anthelmintic activity of ethanol extract of Orthosiphon aristatus (Blume) Miq leaves against H. contortus. The infective H. contortus larvae were divided into six treatment groups: a 0.5% ethanol extract concentration group, a 1% ethanol extract concentration group, a 2% ethanol extract concentration group, a 4% ethanol extract concentration group, a positive control group (+), and a negative control group (-), each with four replicates. The study was conducted in six hours, with observations made at the 1st, 2nd, 4th, and 6th hours. The results showed that the death of the larvae increased with higher ethanol extract concentrations and longer exposure to the ethanol extract of Orthosiphon aristatus (Blume) Miq leaves. The time of death for infective H. contortus larvae given the ethanol extract of Orthosiphon aristatus (Blume) Miq leaves was at the 4th hour, and the effective dose of the ethanol extract as an anthelmintic was at the concentration of 0.5%.

High accumulation of lipids in hepatocytes can trigger an increase in the production of radical compounds, leading to fatty liver disease. This condition induces histological changes in the liver, especially in hepatocytes, and affects the surrounding structures. Mahogany seeds have the potential to act as a hypolipidemic agent in treating fatty liver. Mahogany seeds are known to contain phytochemical compounds which act as antioxidants. This study aimed to determine liver histopathology of rats by inducing high-fat diet after giving mahogany seeds ethanol extract which was observed through the percentage of steatosis, hepatocyte diameter, and hepatosomatic index. This study involved thirty male Sprague Dawley rats, divided into 6 groups: P0 (given commercial feed), P1 (given high-fat diet), P2 (given high-fat diet and simvastatin at a dose of 8 mg/200 g BW), P3, P4, and P5 (given high-fat diet and mahogany seeds ethanol extract at a dose of 14, 28, and 56 mg/200 g BW). The results showed that the hepatosomatic index among all treatment groups did not differ significantly; however, the percentage of steatosis and hepatocyte diameter in the groups given mahogany seeds ethanol extract significantly differed from the group given only high-fat feed. Based on these results, it can be concluded that mahogany seed ethanol extract can maintain the histological structure of the liver in male Sprague Dawley rats with fatty liver.
