Background/Objective: Various Secondary metabolites in Desmodium gangeticum (L.) DC. make this plant medicinally important. Also, this plant is naturally subjected to drought-like conditions; the main abiotic stress relates to low water availability to plants. However, literature is scarce regarding studies on drought stress impact on secondary metabolites content in Desmodium gangeticum (L.) DC. Methods: Plants were exposed to water regimes to generate drought-like conditions, i.e. 200, ml water was given at 3-day intervals for mild stress, 4-day intervals for moderate stress and 6-day intervals for severe stress. The flavonoids, phenolic and alkaloid content of the leaf were estimated at 15 and 30 days after drought stress (DAS). Findings: Desmodium gangeticum plant expressed differential responses in leaves number and size, secondary metabolite contents to water deficit based on the duration of stress applied. Leaves grown per plant decreased as the severity of drought stress increased (mild-11, moderate-8, severe-6 leaves) compared to control (14 leaves). Flavonoid content increased significantly at 15 DAS and decreased significantly by 50% at 30 DAS. Meanwhile, 15 and 30 days after drought stress (DAS), a significant decrease was observed in phenol and alkaloid content. Novelty: Our study highlights the intricate relationship between drought stress and the biosynthesis of biologically active secondary metabolites, flavonoids, phenolic and alkaloids, which can influence the therapeutic properties of Desmodium gangeticum.

Objectives: The synthesis of Polypyrrole based nanocomposites using chemical techniques and then characterize using various techniques to study the Structural, morphological, and Thermal characteristics of these materials. The main objective of this research is to fabricate room temperature operative NH3 gas sensor. Methods: Turkevich method is used for the synthesis of gold nanoparticles. These Gold nanoparticles are further employed to form polypyrrole-based nanomaterials using the Chemical oxidative polymerization method. These nanocomposites were comprehensively characterized using SEM, TEM, X-ray Diffraction, FTIR, UV-vis Spectroscopy, and TGA. The two-probe approach was used to measure electrical conductivity. Synthesized PPy-Fe(ClO4)2-Au nanocomposite was then applied to fabricate room temperature operated gas sensor that can detect ammonia (NH3) gas at low ppm levels. Findings: The SEM of the PPy based nanoparticle shows its globular morphology with size in 180-250 nm. XRD shows an amorphous nature with some crystalline formation indicating Au presence. FTIR reveals prominent peaks showing significant bonds of PPy. The UV-visible spectra of pure PPy shows a peak at 349 nm while PPy-Fe(ClO4)2 and PPy-Fe(ClO4)2-Au show additional peak at 541 nm and 421 nm. The I-V characteristic of PPy-Fe(ClO4)2-Au shows enhanced conductivity of 30.58 Scm-1 which is higher than pure PPy. Novelty: A novel dopant Iron(II) per chlorate Fe(ClO4)2, was added to the nanoparticles to synthesize PPy-Fe(ClO4)2-Au nanocomposites. Since most of the sensors worked at some elevated temperature, this paper presents low ppm level NH3 gas sensing at room temperature which is the key step for this research work.

Objectives: To evaluate the efficiency of the multi-objective battery-swapping electric vehicle transshipment problem by analyzing the total cost and time involved in the entire distribution process. Methods: A multi-objective battery-swapping electric vehicle transshipment model is formulated and a case study on a food grain company is considered to demonstrate the pertinent nature of this model. Due to real-life uncertainty, Fermatean fuzzy parameters are considered in this model. Existing neutrosophic fuzzy programming and linear weighted sum method have been used to obtain the solutions for the multi-objective transshipment model. Findings: A comparative study has been made for both multi-objective electric vehicle transshipment and multi-objective electric vehicle transportation problems with battery swapping as well as charging technology. Optimum Solutions obtained for the case study by using these two prescribed methods reveal that the multi-objective transshipment problem with battery swapping gives the minimum transportation cost and time than the charging technology. Obtained solutions for multi-objective electric vehicle transshipment problems with battery swapping show a reduction of 7.8% in cost and 11.19% in the charging technology. Meanwhile, obtained solutions for multi-objective electric vehicle transshipment problems show a reduction of 14% in cost and 14.4% in time than the multi-objective transportation problem. Novelty: The efficiency of multi-objective electric vehicle transshipment problems with battery swapping technology under the Fermatean fuzzy environment has not yet investigated in the literature. 2020 Mathematics Subject Classification: 90B06.

Integrated Protocol for Phytolith and Diatom Extraction from Carbonised Food Crusts via Ashing V.1 v1
Authors: C. Power Robert , Takase Katsunori
Published: December 2024

Carbonised food crusts on pottery or other receptacles are valuable contexts for the study of ancient meals as they represent in-situ remnants of ancient meals and other preparations. Yet they represent one of the lesser studied contexts for extracting microremains in archaeological research. A variety of approaches have been published for the extraction of microbotanical remains from food crusts (García-Granero et al. 2018; Lusheck and Thompson 2007; Pigford and Zutter 2015; Saul et al. 2013). Some published protocols for the extraction of microbotanical remains from archaeological carbonised food crusts in attempt to co-extract starches and phytoliths simultaneously from a single food crust, often relying on disaggregation to minimise the impact of sampling (García-Granero, et al. 2018; Saul et al. 2013). These methods often rely on hydrogen peroxide (H2O2) to freely liberate food remains from the carbonised food crust matrix. However food crust can be highly durable and resistant to disaggregation, and even if disaggregated, the resulting supernatant will be rich in carbonised particles. If microremain density is low, it is extremely laborious if even possible, to reliably detect microremains in the clutter of carbon. Counting must be aided by removing as much carbon from a sample as practical. Other approaches focus on nitric acid extraction, although effective in isolating phytoliths and producing ‘clean’ samples, it poses some risks to user health. In this method, we highlight combustion with hydrochloric acid ash removal as a simple, fast, and safe method to produce easy to count silica-based microremains in samples with an optional clay removal step based on the rapid phytolith extraction method (Katz et al. 2010).

Background. The research aimed to find a convenient preparative method for the synthesis of tantalum water-soluble complexes from metal oxide, which would not require harsh or hazardous reaction conditions or the use of expensive, less accessible reagents. The application of the triethylamine-hydrogen fluoride complex as an inexpensive and safe surrogate for hydrofluoric acid facilitated the conversion of tantalum oxide into a form suitable for further transformations in aqueous or organic environments under mild conditions and without any restrictions on the use of glassware.

Methods. In this work, a method for dissolution of tantalum pentaoxide, a relatively chemically inert compound, with formation of highly soluble fluoride complex was developed. The variety of techniques were used to identify the complex, such as: IR, UV/Vis and NMR spectroscopy. All materials were of analytical grade and obtained from commercial sources without further purification. The IR spectra of the synthesized compounds were recorded on a Fourier IR spectrometer Perkin-Elmer ВХ (400-4000 cm-1) in KBr tablets. Electron spectra of diffuse reflection (ESD) of polycrystalline of samples in the UV and visible range were recorded on a Varian spectrometer 5000. The intensity was measured relative to MgO or KBr. The solvents were purified according to the standard procedures. All other starting materials were purchased from commercial sources. 1H and 19F NMR spectra were recorded on a Varian Gemini 2000 spectrometer.

Results. It was found that old samples of tantalum oxide, inert to most inorganic and organic acids and bases, are easily converted to fluorotantalates by reacting with commercial trimethylamine hydrofluoric acid complex at room temperature within short reaction times. The reaction is easily scaled up to multigram quantities and the product (NHEt3)2[TaF7] is obtained in essentially pure form after operationally simple workup protocol. Bench stable tantalum complex is insensitive to air and moisture.

Conclusions. A developed protocol can serve as a convenient and safe starting point for the preparation diverse coordination and organometallic tantalum compounds both by fluoride ligand substitution and organic cation exchange. Tantalum oxide hydrofluoride-dissolution – precipitation-by-hydrolysis cycle may also be used for crude tantalum sample purification owing to the crystalline nature of the heptafluoride complex and its other physico-chemical properties.

Background. Complexity and multistage of wine technology increase risks of wine contamination by metal ions. That is why development of reliable, fast and cheap methods of toxic metals determination is actual task. The atomic absorption method possesses all above benefits; however, its sensitivity is not high enough. So, for the heave metals determination in wines on the level of maximum permissible concentration requires additional preconcentration at the probe pretreatment stage. The purpose of present work is the development of the procedure of atomic absorption determination of copper, cadmium, nickel and lead in wines through their selective preconcentration of silicas with chemically grafted iminodiacetic acid groups (SiO2-IDA) and ethylenediaminetriacetic acid (SiO2-EDTA)

Methods. Sorption characteristics of chemically modified silicas for Cu (II), Cd (II), Ni (II) and Pb (II) were studied in dynamic mode, equilibrium concentrations of metal ions were determined by atomic adsorption.

Results. Optimal conditions of Cu (II), Cd (II), Ni (II) and Pb (II) sorption were studied. Sorption – atomic absorption procedure of these metals quantification in aqueous solutions, was proposed. This procedure if suitable for analysis of red and white wines with satisfactory accuracy and reproducibility.

Conclusions. The SiO2-IDA adsorbent appeared low efficient for metals preconcentration in dynamic conditions. The quantitative extraction of all Cu (II), Cd (II), Ni (II) and Pb (II) on SiO2-EDTA takes place at the pH = 4 – 5, while their quantitative elution can be achieved by adsorbent treatment with 1% Thio in 0.1 mol/l HCl. The optimal volume of the eluate is 2 ml for 0.1 g of adsorbent. Proposed approach was successfully applied for preconcentration and following atomic absorption determination of metal ions in red and white wines samples.

Published: December 2024

BACKGROUND: Spinal myeloischemia is a rare but severe neurological disease, associated with high incapacitation level and high social-economical costs due to complications developing during the acute phase. The reasons for its development can include vascular malfomations, spinal stroke, extra- and intramedullary tumors, compression of the spinal cord in cases of vertebral fractures, intervertebral disc herniations, stenosis of the spinal canal at the cervical segment, medical manipulations and impaired segmental circulation during the anesthesia, lumbar puncture and surgical interventions. CLINICAL CASE DESCRIPTION: The presented clinical observation provides a description of the iatrogenic complication that has developed in a patient aged 52 years after discectomy and installation of the disc prosthesis due to the development of disco-radicular and spinal conflict, resulting due to the С5/С6 dorsomedial intervertebral hernia, the clinical manifestations of which, besides pain, included weakness in the left upper limb, causally related to the focus of intramedullary ischemia at the unilateral side. At the early post-surgery period, asymmetrical tetraparesis was revealed with the predominance in the distal segments of the left upper limb and with impaired functions of the pelvic organs, caused by the expansion of the ischemia zone in the gray and white matters in the anterior areas of the lower cervical segments of the spinal cord. CONCLUSION: The timely initiation of combined medication therapy and the staged rehabilitation, conducted by the multi-disciplinary team, have provided the restoration of the impaired functions and the quality of life for the patient. The proposed methods can be useful in the treatment of patients with compression-related and non-compression-related vascular myelopathies.

BACKGROUND: Chronic calculous cholecystitis is the most widespread disease in scheduled surgery departments, which in 10–15% of observations is complicated by choledocholithiasis. As of today, the commonly acknowledged staged treatment tactics includes first an endoscopic lithoextraction, later followed by the laparoscopic cholecystectomy, with the durations of performing the latter not being defined. AIM: To define the optimal timings of performing the laparoscopic cholecystectomy after an endoscopic lithoextraction in cases of chronic calculous cholecystitis, complicated by choledocholithiasis. METHODS: The research included patients with chronic calculous cholecystitis, complicated by choledocholithiasis, which during the period of 2016–2023 years have received surgical aid at the Federal State Budgetary Institution “Federal Scientific and Clinical Center” of the Federal Medical-Biological Agency of Russia (n=87). Simultaneous endoscopic lithoextraction and laparoscopic cholecystectomy were carried out in 20 patients; 19 patients were operated within a single hospitalization with undergoing endoscopic lithoextraction and in 3 days — laparoscopic cholecystectomy (early cholecystectomy); in 48 patients laparoscopic cholecystectomy was delayed by 1–2 months after the endoscopic lithoextraction (interval cholecystectomy). RESULTS: When comparing the treatment results in three groups of patients, no statistically significant differences were observed, however, in the group of interval cholecystectomy, a tendency was shown for increasing the surgery duration, the conversion rate and the number of complications. CONCLUSION: In patients, not having signs of severe course of the disease, it is possible to perform simultaneous endoscopic lithoextraction and laparoscopic cholecystectomy. In the absence of complications, the applicable options include early (within 3 days) conducting the laparoscopic cholecystectomy, which does not worsen the results, however, it alleviates the necessity of repeated hospitalization and, probably, slightly decreases the risk of complications.

AIM: To study the adhesive strength of composite restoration with hard tissues in laboratory samples of the frontal and chewing groups of teeth before and after thermal cycling.
METHODS:

Preparation of test samples.
Laboratory methods - determination of the adhesive strength of samples of compressive restorations: 2.1 Before thermal cycling; 2.2 After thermal cycling.
Statistical data processing in the SPSS Statistics program

RESULTS: The results of a comparative assessment of the adhesive compressive strength showed that in the samples of teeth of the frontal group before thermal cycling in groups 1Fa and 2Fa amounted to 1663.6 (1574.6; 2175.1) N and 2151.5 (967.9; 3970.3) N, respectively. The difference between them is unreliable (p=0.538), which confirms the homogeneity of the groups. After thermal cycling in groups 1Fb and 2Fb, the adhesive compressive strength indicators were 1353.3 (1219.2; 2096.8) N and 1620.7 (847.2; 2434.7) N, respectively. The difference between groups 1Fb and 2Fb is unreliable (p=0.868). The adhesion strength indicators before and after thermal cycling in groups 1Fa and 1Fb (p=0.017) and in groups 2Fa and 2Fb (p=0.017) are statistically significant. In the samples of teeth of the chewing group, the adhesive strength indicators before thermal cycling in groups 1Cha and 2ChA were 4100.0 (2818.1; 48401.4) N and 3800.0 (2000.0; 4500.0) N, respectively. The difference between groups 1Cha and 2Cha is unreliable (p= 0.476), which indicates the effectiveness of adhesion of various adhesives. In the samples of teeth of the chewing group, the adhesive strength after thermal cycling in groups 1Chb and 2Chb amounted to 3479.5(2708.8; 3995.6) N and 1999.0 (1646.3; 3120.8) N, respectively. The difference between them is unreliable (p=0.153), which confirms the effectiveness of adhesion and the safety of the restoration-tooth complex.
CONCLUSIONS: The chewing group of teeth can withstand a heavy load in comparison with the teeth of the frontal group. In all groups, there is a decrease in the strength of the joint after thermal cycling. This is due not only to the type of adhesive system, but also to the features of the anatomical structure of the teeth of the chewing group, their shape, area, and surface relief.

Published: December 2024

BACKGROUND: Alkyl-bis-imidazole-4,5-dicarboxylic acids can be used both in the production of polymers with pronounced fluorescent properties and as potential antiviral agents. However, there is currently no simple method for the synthesis of alkyl-bis-imidazole-4,5-dicarboxylic acids with a wide range of substituents at both 1, 1ʹ and 2, 2ʹ positions. Therefore, the search for alternative, easier ways to synthesize compounds of this series remains relevant.
AIM: To develop a method for obtaining 2-substituted bis-imidazole-4,5-dicarboxylic acids connected at positions 1, 1ʹ by an alkyl chain of various lengths containing substituents of various lengths and nature at positions 2, 2ʹ (alkyl substituents of various lengths and heteroaryl substituents).
MATERIALS AND METHODS: Compounds of a number of bis-imidazole-4,5-dicarboxylic acids were obtained using methods of fine organic synthesis.
RESULTS: It has been shown that the oxidation of 1,1ʹ-(alkyldiyl)-bis-(2-alkylbenzimidazoles) with hydrogen peroxide in concentrated sulfuric acid leads to the production of targeted 1,1ʹ-(alkyldiyl)-bis-(2-alkylimidazole-4,5-dicarboxylic acids) in preparative quantities.
CONCLUSIONS: A new preparative method has been proposed for the preparation of 1,1ʹ-(alkyldiyl)-bis-(2-alkylimidazole-4,5-dicarboxylic acids).

Published: December 2024

Antimicrobial peptides have gained prominence in scientific research due to their biological potential and antifungal capacity. These peptides are small proteins intrinsic to the system of many living organisms and have activity against microorganisms, bacteria, fungi, viruses and helminths. Therefore, fungi of the genus Aspergillus spp are very common in nature, and affect the production of peanuts, almonds, chestnuts and others. Thus, the present work sought a strategy to reduce or mitigate the activity of this fungus in peanut seeds during germination by applying three different dosages (3.6, 4.8 and 7.2 mg/mL) of the antimicrobial peptide Ctx(Ile21)-Ha in ultrapure water, and had as objective to evaluate its effects on germination parameters in comparison with the use of the commercial fungicide (Mayran), widely used in peanut crops in the Tupã - São Paulo. The most promising results occurred with dosages of 3.6 mg/mL and 7.2 mg/mL of the peptide, and the Mayran fungicide also showed high efficiency rates for peanut germination, but it presents high toxicity for the producer who handles the fungicide.

Published: December 2024

In 2016, the United Nations (UN) created the 2030 Agenda, which seeks sustainable management and efficient use of resources, including reducing food waste and waste generation. This agenda is based on the principles of sustainable development and expands on the objectives of the Millennium Development Agenda, encompassing economic development, the eradication of poverty and hunger, social inclusion, environmental sustainability and good governance. In Brazil, actions aligned with the 2030 Agenda have been implemented, regarding sustainable public procurement, regulated by Decree No. 7,746/2012. These contracts promote sustainable practices, such as preference for recycled and biodegradable products. Programs such as the Food Acquisition Program (PAA) and the National School Feeding Program (PNAE) are crucial to meeting the Sustainable Development Goals (SDGs), especially SDG 12, which aims for responsible consumption and production practices. The PAA encourages family farming and sustainability, while the PNAE promotes food and nutritional security in schools by integrating local and sustainable production. These initiatives reflect Brazil's commitment to sustainable development, benefiting the rural economy, reducing poverty and promoting socio-environmental sustainability.

Published: December 2024

This study systematically reviews the literature on traceability in the cotton textile chain to investigate its scope in all chain links and its relationship with adding value to the product. The analysis included 31 articles published between 2014 and 2024, identified on the Scopus database. The results showed a significant emphasis on the Production and Industrialization links, with 87.1% of the articles focusing on these stages, while Retail and Consumer received limited attention. It was found that traceability adds value through transparency, sustainability, authenticity, and technological innovation, but lacks greater integration and communication in the final links. The study highlights the need for a holistic approach that aligns traceability practices with market demands for sustainability, trust, and social responsibility.

Published: December 2024

Smartwatches are wearable technologies mostly used to produce health-related data. This paper focuses on smartwatch uses in terms of surveillance mechanisms. We ask whether, in the example of smartwatch, wearable technologies used in self-regulation facilitate the self-optimization of human bodies. We refer to several scholarly works using the concepts of self-tracking culture, quantification, governance of self and self-optimization. We organize our literary and methodological sources in three dimensions to construct an operational analysis: quantified self, self-definition, and governance of the self. We conducted in-depth interviews with a total of thirteen people by using snowball sampling. The average duration of the interviews was 30 minutes. We recorded the interviews with the permission of the respondents. The most important criterion in choosing the people to be interviewed was that they had five months or more of experience using the watch since the smartwatch requires a certain amount of time to get used to it and develop a habit of use. All interviewees had university degrees and an income-generating profession, mostly white-collar. The paper argues that the smartwatch, as a tool of quantification, encourages users to monitor themselves in order to be responsible individuals for their own health. However, we also acknowledge that the use of smartwatch does not straightforwardly produce empowering or disempowering outcomes for the users. There are dualistic aspects in its use that require further sociological considerations. Although the smartwatch is a tool of monitoring, its different connotations must be understood in its specific relation to the users.

Neoliberal iktisadın kamu hizmetini bir piyasa ilişkisine dönüştürmesi sonucunda, dünyanın birçok yerinde olduğu gibi, Türkiye’de de sağlık alanı önemli ölçüde kapitalist bir anlayışla yeniden yapılandırılmıştır. Bu süreçle uyumlu olarak, sınırları bilimsel ölçütlerle oluştuğu varsayılan tıp uzmanlık dalları, özellikle değişim değeri yüksek, rekabetçi karaktere sahip, serbest piyasa metâı olabilen işlemlerin yetki sınırlarındaki çatışmalar nedeniyle tartışmalı hâle gelmektedir. Teknolojik yeniliklerin de katkısıyla, tıp uzmanlık alanlarının yapılanmış yetki sınırları hem bilimsel anlamda hem pratikte belirsiz bir alan oluşturmaktadır. Sağlığın rekabetçi piyasa cinsinden tanımlanması, daha önce birbirlerinin pratik alanına yaygın olarak girmeyen tıp uzmanlık dallarının, bu sınırları sıklıkla ihlal etmesi sonucunu doğurmuştur. Tıp uzmanlık dallarının yetki çatışmaları bedenin birçok bölümünde mevcuttur. Ancak bunların arasında, kozmetik yönelimi olan işlemler daha belirgin çatışmalara neden olmaktadır. Kozmetik yönelimli tıbbî işlemlerin önemli bir kısmı yüz üzerinde yapılmaktadır. Bu nedenle, yüze müdahale etme yetkisine sahip başlıca üç tıp uzmanlık dalının (Dermatoloji, K.B.B., Plastik Cerrahi) temsilcilerinin, yetki sınırı ihlalleri konusundaki deneyimlerini anlamaya yönelik bir araştırma tasarlayıp yürüttük. Araştırma sonucunda, karmaşık ve belirsiz bir yüze müdahale pratik alanının varlığı ortaya konmuştur. Alanın belirsizliği, istenmeyen ya da öngörülmeyen bir sonuç değil, neoliberal sağlık piyasasının çalışma mantığı olarak teşhis edilmiştir. Yüzün araştırma sahası olarak seçilmesinin bir diğer önemli nedeni, akışkan modernlik ortamında görselliğin bir hakikat rejimi hâline gelmesi, görünümün, varoluşun kendisine dönüşmesi olarak ayrıştırılabilir. Bu makale, belirsizliğin temel ilke olduğu yüze müdahale pratik alanındaki aktörlerin yalnızca tıp uzmanları olmadığını, bir dizi ekonomik ve siyasî aktörün de bu karmaşık ilişkiler ağının bileşenleri olduğunu tartışmaktadır.
Michel Foucault’da İktidar–Disiplin İlişkisi ve Zamansallaştırma

İnsan deneyimi sosyal süreçler ve dinamiklerle şekillenir, bu da toplumsal değişim, kimlikler ve öznellik ifadeleri üzerinde etkili olur. Toplumların zamanı kavrama ve deneyimleme biçimleri de bu ilişkilerle yorumlanabilir. Bu anlamda zaman toplumların onu kavrama ve kullanma biçimlerine göre farklılaşması durumu zamansallığı ortaya çıkarır. Zamansallaştırma (temporalization) sosyal sistemde önemli bir kavramdır ve iktidar ile toplum arasındaki ilişkiyi etkiler. Özellikle Avrupa sömürgeciliği döneminde zamansallaştırma, yerlilerin boyunduruk altına alınmasında direnişi kırmak için araç olarak kullanılmıştır. Michel Foucault’nun çalışmaları, modern toplumlarda iktidarın bilgi, gözetim ve normlar aracılığıyla işlediğini savunur ve zamansallaştırma kavramı bu bağlamda merkezi bir rol oynar. Foucault'ya göre, zamanın iktidar tarafından düzenlenmesi, bireylerin davranışlarını ve düşüncelerini denetlemek için kullanılır. Zamansallaştırma bireylerin özgürlüğünü sınırlar, yabancılaşma ve güçsüzlük hissi oluşturur. Foucault, modern toplumlarda zamansallığın bireyler üzerindeki etkilerini analiz ederek, zamanın disiplin ve kontrol aracı olarak nasıl kullanıldığını göstermiştir. Foucault açısından modernite ile birlikte zamanın yönetilmesi, bireylerin disipline edilmesi ve toplumsal ritimlerin kontrolü bakımından önem kazanmıştır. Bu süreçte teknolojik gelişmeler de zamansal disiplini artırmış ve zamanın yönetimi iktidarın bir aracı haline gelmiştir. Bu çalışmada Focault’nun iktidar-disiplin ilişkisi içerisinde zamansallık görüşleri ve zaman üzerine ortaya konmuş sosyolojik ve felsefi düşünceler içerisindeki yeri ele alınmaya çalışılacaktır.
SELECTING THE OPTIMUM AMOUNT OF RECYCLED POLYPROPYLENE NONWOVEN WASTE IN SPUNBOND PRODUCTION FOR SUSTAINABILITY
Authors: Değirmenci Züleyha
Published: December 2024

Structural Abstract
During the Covid-19 pandemic, there was a significant increase in the use of polypropylene-based masks, leading to challenges related to raw material waste and supply limitations. This study aims to identify the optimal ratio of recycled and standard polypropylene fibers to produce a nonwoven spun-bond fabric with the best possible strength and elongation properties. In the rapidly expanding industry, polypropylene (PP)-based nonwoven fabrics (spunbond and meltblown) are increasingly being recycled by converting fabric waste into granules, which are then blended with virgin PP in specific proportions for reuse in production. This research focuses on analyzing the tensile strength and elongation at break of spunbond fabrics. First, fabric wastes from Spunbond-Meltblown processes were converted into granules, and their melt flow index (MFI) values were measured. These granules were then blended with virgin polypropylene fibers in varying proportions, resulting in five different spunbond fabric samples. The mechanical properties of these samples were compared with those of a fabric produced solely from virgin PP. The optimal mixing ratio of recycled to virgin fibers was then determined based on the results. The MFI of the recycled PP1 waste was measured at 38, while the MFI of a 75%-25% Spunbond-Meltblown waste blend (Recycle-PP5) was 104. Spunbond fabrics were produced by blending Recycle-PP1 granules with virgin raw material at ratios ranging from 0% to 20%. It was found that a 10% blend of recycled granules yielded the best results without compromising fabric quality. Higher proportions of recycled granules led to defects in the fabric. For instance, the tensile strength of spunbond fabrics containing 20% Recycle-PP5 granules decreased by approximately 26.9% compared to the fabric produced with 100% virgin PP. This study demonstrates the potential for using recycled granules in spunbond fabric production for specific applications, based on the observed strength properties. A key distinction of this research from existing literature is the identification of the most effective blending ratio of recycled and virgin polypropylene in a conventional production setting.
Prevalence of T3 thyrotoxicosis and it’s management in new onset thyrotoxicosis patients: a prospective observational study

Published: December 2024

Background: T3 toxicosis is a subtype of thyrotoxicosis where total triiodothyronine (TT3) level is high but total thyroxine (TT4) level is normal in presence of suppressed thyroid stimulating hormone (TSH). Accurate and rapid diagnosis is crucial in management of T3 toxicosis.
Methods: In this prospective observational study from India, newly diagnosed thyrotoxicosis patients were enrolled. T3 toxicosis patients were diagnosed based on diagnostic criteria. T3 toxicosis patients were randomized into two arms, based on dose of carbimazole (CBZ) used for treatment. All patients are following up for 12-14 weeks.
Results: Prevalence of T3 toxicosis was 8.5% in this study. 75% were diagnosed as Grave’s disease (GD) and 25% were diagnosed as toxic nodular goiter (TNG). Low dose (5 mg/day) of CBZ is safer and more effective than higher dose (20 mg/day).
Conclusion: Present study suggests that a significant number of patients with thyrotoxicosis are suffering from T3 toxicosis. So, for correct diagnosis of thyrotoxicosis one should investigate for TT3, TT4 and TSH, otherwise we can misdiagnose the T3 toxicosis as subclinical thyrotoxicosis (SCT). Majority of T3 toxicosis patients are diagnosed as GD. Low dose of CBZ is very much effective and safe in these patients. We recommend low dose of CBZ in all patients with T3 toxicosis.
Comparative analysis of ligation of intersphincteric fistula tract and fistulectomy for complex fistula-in-ano: a prospective observational study
Authors: Elancheliyan Balaji , K. S. Ravichandran
Published: December 2024

Background: Fistula-in-ano is a debilitating condition that poses significant treatment challenges, particularly in complex cases. Ligation of intersphincteric fistula tract (LIFT) and fistulectomy are two common procedures used for management, with differing outcomes in recurrence, pain, and morbidity. This study aimed to compare these two methods in a resource-limited setting.
Methods: This prospective observational study was conducted at Shri Sathya Sai Medical College and Research Institute from July 2023 to July 2024 – six months of study and six months of follow up period. Sixty patients diagnosed with complex fistula-in-ano were randomly assigned to either the LIFT or fistulectomy group. Postoperative outcomes, including recurrence rates, pain (using the visual analogue scale), bleeding, and incontinence (Browning and Park’s scale), were recorded and analyzed using statistical package for the social sciences (SPSS) version 22.0 software.
Results: The recurrence rate was significantly lower in the LIFT group (10%) compared to the fistulectomy group (37%, p=0.0069). LIFT patients experienced less postoperative pain (mean VAS score: 3.5±1.2) compared to fistulectomy (mean VAS score: 5.2±1.5, p=0.0082). Bleeding rates and incontinence showed no significant differences between the groups.
Conclusions: LIFT is a superior technique for managing complex fistula-in-ano due to lower recurrence rates and reduced postoperative pain. This sphincter-preserving method is particularly advantageous in resource-limited settings.
