Published: June 2023

Abstract
The pulsed eddy current (PEC) is an effective method for the online detection of laser welding seam defects. The joint wavelet dictionary learning method is proposed for solving the separation problem of the broad frequency harmonic and local non-smooth distortion of the PEC signal. The Haar and Gabor wavelet is adopted to be the basic function, which is extended to be the over complete wavelet dictionary library by cyclic migration. The sparse representation of the defect PEC signal is obtained by combining the joint wavelet dictionary with the orthogonal matching pursuit algorithm. The feature parameters of the PEC signal are calculated and inputted into the support vector machine to detect the laser welding seam defect intelligently. The validity of the proposed method is further verified by the experimental results, demonstrating the effectiveness of the classification identification and quantitative assessment of the pore and crack.

Published: June 2023

In type 2 diabetes mellitus, increased platelet activity is crucial for the emergence of vascular complications. Mean platelet volume (MPV), an indicator of enhanced platelet activity, may be helpful in identifying the thromboembolic events that lead to these vascular complications. This study aims to assess MPV in Type 2 Diabetes patients and investigate the relationship between MPV and glycaemic and diabetic complications. : A comparative cross-sectional study was carried out on 266 subjects (133 diabetic patients and 133 nondiabetic controls) at B.P Koirala Institute of Health Sciences for a period of one year. MPV was analyzed in both the groups and the potential association of MPV with diabetic complications and glycaemic parameters was evaluated. Statistical analysis was carried out with Student t-test and Pearson Correlation Coefficient.: The results of the study showed that diabetics' MPV was considerably higher than that of non-diabetic controls (10.07 + 1.41 vs. 7.47 + 0.60 fl, P0.001) and that diabetic patients who had complications had significantly higher MPV than those who did not (10.61 + 1.35 vs. 9.37 + 1.15 fl, P0.001). Retinopathy (p=0.004), nephropathy (p=0.001), and Peripheral artery disease (p=0.03) were diabetes complications with significantly increased MPV. With regard to HbA1C, FBS levels, and the duration of diabetes, MPV demonstrated a statistically significant positive connection (p0.001 and positive r-value).: MPV is a cost-effective tool in the early detection of vascular complications in diabetes and hence proves to be a promising indicator in preventing vascular complications.

Published: June 2023

While assessing whether a patient requires surgery or conservative treatment, the thyroid FNAC is crucial. “The Bethesda System of Reporting Thyroid Cytopathology” was introduced to resolve the problem of standardising terminology in Thyroid FNA diagnosis. This study aims to evaluate the histopathological correlation and to also assess the diagnostic accuracy of TBSRTC at an institutional level with respect to histopathology. Additionally, reclassification of these cases in accordance with new Update of WHO Classification of Thyroid tumors 2022.This is a 3-year retrospective study of thyroid lesions from August 2019 to August 2022 comprising of 160 cases. Data was retrieved from institutional database and analysed. Fine needle aspiration Cytology- Histopathological correlation followed by determination of diagnostic accuracy of TBSRTC was done using Sensitivity, Specificity, PPV, NPV and accuracy. Reclassification was done on the 160 histopathological diagnosis based on the new updated classification.Study showed female predominance and largest cohort belonged to the age group of 21–40 years. Cytohistopathological correlation was done and 4 discordant cases were identified. The Sensitivity, Specificity, PPV, NPV and Accuracy was found to be 95.77, 98.87, 98.55%, 96.7% and 97.5% respectively. On reclassification, the tumors were now classified based on cell of origin and maximum no. of cases were identified under the category of Follicular- cell derived.FNAC is a sensitive and specific method of evaluating thyroid lesions. TBSRTC shows excellent diagnostic accuracy in detecting malignant lesions and can be used for screening neoplasm. The new classification demonstrates classification based on tumour cell of origin. It is crucial for Clinicians and Pathologists to be informed of new terminologies and classification schemes to aid more therapeutic options for patients.

Ewing sarcoma is the second most common sarcoma involving the bones in children and adolescents. Published data on the clinical features, morphology, translocation and follow-up of patients with Ewing sarcoma from India, is sparse. Objectives of this study were to analyse the clinico-pathologic features of Ewing sarcoma and compare with translocation status, BCoR immunohistochemistry, treatment and survival. 406 cases of Ewing sarcoma were diagnosed in the Department of Pathology, Christian Medical College, Vellore during the period 2008-2015. 135 patients underwent molecular testing for common translocations by RT-PCR and were included in this study.Mean age of patients at diagnosis was 22 years. Most common location of tumour was appendicular skeleton (31.4%) and 19% had solid organ involvement. Distant metastasis was present in 21.5% patients. Translocation was seen in 63 (46.7%) cases, EWS-FLI1 type I (87%), EWS-FLI1 type II(11%) and one patient had EWS-ERG translocation. Seven out of 30 patients were classified as “Sarcoma with BCOR genetic alteration”. Patients who underwent 6 cycles of chemotherapy had a better mean survival. Mean follow-up was 13.72 months and 3 year event free survival of patients was 93.8%.Percentage of viable tumour &#60;10% was the only significant histologic parameter predicting survival. Age at diagnosis ≤15yrs, female sex, size ≤12cm, extra-osseous site, chemotherapy and translocation positivity predicted an improved survival. This study has analysed the type of mutations/translocations seen in a subset of Indian patients with Ewing sarcoma and correlated the clinical and pathological factors affecting survival.

Published: June 2023

This study aims to demonstrate the efficacy of gamification in developing HTML programming skills and academic achievement motivation for 10th-grade students. Despite the significance of computer programming in developing students' thinking, many students still need more motivation to learn it. One of the entertaining strategies of computer programming is gamification. The study used a quasi-experimental design for two groups. The experimental group (N=18) was taught by gamification and the control group (N=17) was taught by the traditional teaching method. The researcher conducted a pre-test to determine the equivalence between groups using a valid and reliable practical test and scale. After three-weeks of teaching, the same test and scale were applied to compare the groups. The result showed statistical differences between the two groups in favor of the experimental group in programming skills and all academic achievement motivation dimensions. This study recommended that using gamification in teaching programming languages to students at different stages would help computer teachers. More research should be conducted to investigate the impact of gamification on teaching different programming languages.

Published: June 2023

Background: The aim of the present study is the determination of the effects of seasonal variations on the proximate analysis, cholesterol content and fatty acid compositions of Helix aspersa.
Materials and Methods: Garden snails (Helix aspersa) were picked up by hand from the Central Anatolia Region of Turkey, in autumn (November) and spring (April) in 2011. Fatty acid methyl esters (FAMEs) and cholesterol analysis were analyzed by gas chromatography (GC). The protein contents of snail muscle were determined with Kjeldahl distillation units. Statistical comparisons were made by using SPSS Software (version 16.0).
Results: Thirty different fatty acids of different saturation levels were detected. As the predominant fatty acids, stearic acid (C18:0), oleic acid (C18:1ω9), linoleic acid (C18:2ω6), palmitic acid (C16:0), arachidonic acid (C20:4ω6), eicosadienoic acid (C20:2) and linolenic acid (C18:3ω3) were found in Helix aspersa. Palmitic acid (C16:0) was identified as the major SFA in autumn and spring. Linoleic acid (C18:2ω6), eicosadienoic acid (C20:2) and arachidonic acid (C20:4ω6) have the highest levels among the PUFAs. In the present study, ω3 were found 5.48% and 13.94% in autumn and spring, respectively.
Conclusion: Linolenic acid and omega-3 fatty acid amounts in the spring increased significantly but cholesterol content was not affected in Helix aspersa both in season.

Published: June 2023

Background: Artemisia herba alba, classified into the family of Asteraceae, is an aromatic herb that is traditionally used as a purgative and anti-pyretic folk medicine by rural people of south Tunisia. This study reports the first identification of antimicrobial peptides from this medicinal plant that inhibited the growth of several food-borne pathogenic bacteria.
Materials and methods: The extraction and purification of peptidic agents from Artemisia herba alba, have been performed using precipitation by ammonium sulfate of a phosphate buffer crude extract obtained from the plant leaves, followed by reverse-phase HPLC on a C18 column. The mass of the peptides was estimated by SDS-PAGE electrophoresis, followed by a gel overlay assay and ultra-filtration through a 5 kDa cut-off membrane. Fractions from every purification steps were sampled and assayed for activity towards different food-borne bacterial strains pathogenic and non pathogenic to humans.
Results: The phosphate buffer crude extract, as well as its ammonium sulfate precipitate, designated AS-P, inhibited the growth of Listeria monocytogenes, Staphylococcus aureus, Bacillus cereus sensu stricto and the new approved species Bacillus cytotoxicus. AS-P MICs (minimum inhibitory concentrations) ranged from 0.241 to 3.8 mg/ml proteins for L. monocytogenes and B. cereus sensu stricto (strains ATCC10987 and IP5832), respectively. The bioactive AS-P molecules were stable up to 10 minutes heating at 120°C and they resisted organic solvent effects. Antimicrobial activity of A. herba alba AS-P decreased to 40 and 60% after proteolytic treatment with trypsin and proteinase K, respectively, suggesting peptides being responsible for the A. herba alba AS-P activity. The mass of antibacterial A. herba alba peptides was estimated below 5 kDa. Two AS-P fractions, eluted at 40 and 37% acetonitrile, showed antibacterial activity when assayed against L. monocytogenes.
Conclusion: A. herba alba could make a new source of novel natural anti-infective agents that could be used in food bio-preservation as natural additives or in human infectious disease treatments against multi-drug resistant pathogens.

Background: Type 2 diabetes is a chronic metabolic disorder. Recently, dipeptidyl peptidase IV (DPP-IV) inhibitors that protect incretin hormones from being cleaved by DPP-IV have been used as drugs to control glycemia. This study examined the potential hypoglycemic effect of amaranth grain storage protein hydrolyzates to control postprandial glycemia in streptozotocin (STZ)-induced diabetic mice as a model system of diabetes, and their inhibition mode on the enzyme.
Material and Methods: Amaranth grain proteins were isolated and hydrolyzed and fractionated by gel filtration. The DPP-IV inhibitory activity of hydrolyzates as well as their kinetic parameters were assessed. Selected hydrolyzates (300 mg/kg body weight) were administered in a single administration-study (SAS) or in the same concentration during a four-week chronic daily dosing study (FWCDDS) in order to observe the effect on postprandial glycemia of diabetic mice.
Results: Albumin 1, Globulin and Glutelin hydrolyzates (GluH) competitively inhibited DPP-IV in vitro (Ki= 0.11-5.61 mg/mL). GluH called Glu.III (IC50= 0.12±0.01 mg/mL) considerably inhibited DPP-IV activity. GluH identified as GluH24 improved glucose tolerance significantly (p

Background: Steroidal and non-steroidal anti-inflammatory drugs are most commonly used to treat inflammation, and shown to have severe side effects. In this study, we aimed at evaluating the anti-inflammatory and acute toxicity effects of Baccharoides schimperi (DC.) in order to get new anti-inflammatory agents of natural origin.
Materials and methods: The aerial part of the plant was dried under shade, ground and extracted with 96% alcohol (BSE). It was further fractionated in sequence to n-hexane (BSH), chloroform (BSC) and methanol (BSM) soluble fractions.
Acute toxicity was evaluated by oral administration of plant and hind paw induced-edema method in rats was used for the anti-inflammatory evaluation.
Results: The BSE was found safe up to the dose level of 3 g/kg b.w. and showed LD50 value 7.250 g/kg body weight (b.w.) in mice. BSE showed significant anti-inflammatory effect (62.91%) at 500 mg/kg b.w. Further the n-hexane, chloroform and methanol fractions of BSE were tested for anti-inflammatory activity. The n-hexane fraction (BSH) exhibits significant activity (64.87%) at 400 mg/kg b.w. The methanol fraction (BSM) showed dose dependent activity, highest activity (60.42%) was observed at higher dose 400 of mg/kg b.w. In chloroform fraction (BSC) no significant activity was observed.
Conclusion: The results of the study revealed that the plant is safe to the experimental model and recommended as a potential source of anti-inflammatory agent.
