Published: February 2024

Global warming occurs due the high concentration of Greenhouse Gases (GHG) in the atmosphere, which is called the greenhouse effect. The highest greenhouse gas that causes global warming that is being piled up in the atmosphere due human activity is carbon dioxide. Data on the average increase in global carbon dioxide (C02) concentrations are assumed contain elements of trend and seasonality. Holt-Winter's Multiplicative Triple Exponential Smoothing Method and Multiplicative Classical Decomposition the best choices in predicting data that contains trend and seasonality elements. Forecasting data on the global average increase CO2 has the objective of predicting data for the next 12 periods. The data used is data on the global average increase for the period January 2013 to December 2022. The prediction error measure used is MAPE (Mean Absolute Percentage Error). The results of the analysis on the Triple Exponential Smoothing Holt-Winter's Multiplicative method obtained a MAPE value of 0.09395%, indicating very good prediction category, while the results of the analysis of the Multiplicative Classical Decomposition method had a MAPE value of 0.07021%, which means that it has very good category in do forecasting. Based on the MAPE value obtained, the best method is the Multiplicative Classical Decomposition method.
Optimization of magnetic properties of MnFe2O4 by modulating molarity of NaOH as precipitating agent
Authors: Gulati Sudha , Gokhale Shubha , Luthra Vandna 
Published: February 2024

Abstract
MnFe2O4 nanoparticles were synthesized using the co-precipitation method with a wide range of molar concentrations of sodium hydroxide 0.76 M−3.0 M. X-ray diffraction, field effect scanning electron microscopy, transmission electron microscopy, and vibrating sample magne-tometry were employed to characterise the structural, morphological, and magnetic characteristics of nanoparticles. Field effect scanning electron microscopy and transmission electron microscopy images show that the particles were spherical in shape for all the samples except for sample prepared at a molar concentration of 1.3 M. Particle shape was found to depend on the molar concentration of NaOH. The hysteresis loops of the samples possessed a very small area and low coercivity. The crystallite size (cs), saturation magnetisation, coercivity, retentivity, squareness ratio and anisotropy constant were found to be dependent on the molar concentration on NaOH. M
S was noted to be at a maximum of 64.4 emu g−1 at a molar concentration of 1.3 M. The ratio t/cs (where t is the thickness of the dead layer) was calculated to account for the variation in M
S. H
C was found to be maximum of ∼52 Oe at molar concentrations between 1.0 M and 2.0 M. M
r and M
r/M
S were found to be a maximum of 8.95 emu g−1 and 0.15, respectively, for the molar concentration of 2.0 M.

Abstract

Objectives
The cardiovascular mortality risk is greatly increased in patients with chronic kidney disease (CKD), especially in dialysis patients, due to atherosclerosis. Platelet activating factor acetylhydrolase (PAF-AH) is an enzyme that hydrolyzes platelet activating factor (PAF). Valvular calcifications and PAF-AH are associated with atherosclerosis. However, little is known about the status of PAF-AH activity and valvular calcification in dialysis patients. Therefore, the aim of this study was to investigate the status of these parameters in CKD patients.

Methods
This study included 92 chronic renal failure (CRF) (dialysis group), and 86 CKD patients (non-dialysis group). Echocardiography was performed to assess valvular calcification.

Results
There was no significant difference between the dialysis and CKD groups in terms of PAF-AH activities. However, when comparisons were stratified according to the presence of valve calcification, higher PAF-AH activity and N-terminal pro-B-type natriuretic peptide (NT-proBNP) levels were evident in patients with calcification compared to those without. Additionally, the CRF group also exhibited elevated PAF-AH and NT-proBNP levels. While elevated NT-proBNP persisted in the CKD group, in contrast, changes in PAF-AH were not significant.

Conclusions
The results of this study suggest that high PAF-AH and NT-proBNP levels are associated with valvular calcification in dialysis patients. Both biomarkers may be used as a risk factor for calcification. Furthermore, inhibition of PAF-AH activity may be a treatment target to reduce calcification.

Background. Training programs are part of training management that need to be properly and correctly prepared and implemented.
Study Purpose. The aim of the study was to evaluate the effects of an 8-week program of resistance training, carried out at a specific preparation phase, on the performance of male junior volleyball athletes.
Materials and methods. This study was conducted as experimental research, with a sample of 24 male volleyball athletes ([mean ± SD] age: 17.96 ± 1.23 years; body weight: 75.56 ± 7.80 kg; height: 180.46 ± 7.14 cm; body fat: 17.62 ± 3.36%) who were randomly divided into experimental group (EG): n = 12 and control group (CG): n = 12. The training program lasted for eight weeks and took place at a specific preparation phase.
Results. There was a significant increase in the indicators handgrip dynamometer left (p<0.014), handgrip dynamometer right (p<0.001), vertical jump (p<0.001), sit-and-reach test (p<0.000), leg dynamometer (p<0.000), and back dynamometer (p<0.001) in the experimental group after being given strength training treatment for eight weeks.
Conclusions. When strength training is included in volleyball training, it can increase the performance in power, strength, and flexibility, especially when carried out at a specific preparation phase. Incorporating targeted stimuli, such as strength training, into training sessions appears to be a secure method of training for this age group and may help to contribute to continuous and gradual improvements in neuromuscular adaptation.

Authors: Gomba Victoria E. , Unachukwu Chioma , Chinenye Sunny 
Published: February 2024

Background: Several studies have identified that a decline in renal function as occurs in chronic kidney disease (CKD) is associated with thyroid dysfunction among other endocrine disorders. The prevalence and pattern of thyroid dysfunction in CKD patients in our environment is however not known. This study aimed to determine the prevalence and pattern of thyroid dysfunction in dialysis naïve CKD patients in a tertiary hospital in Southern Nigeria.
Methods: This was a cross sectional study involving 100 participants with established CKD and 100 age and sex matched healthy controls. Relevant data were collected using an interviewer based questionnaire. Samples collected from the participants were assayed for fT3, fT4, TSH and serum creatinine. Analyses was done using version 25 of the SPSS software at a 95% confidence interval and a p value of <0.05 was considered statistically significant.
Results: There were 93 males and 107 females with mean ages of 46.3±15.9 and 45.7±14.9 years for the CKD and control participants respectively (p=0.7587). The prevalence of thyroid dysfunction was 45% in the CKD group and 4% in the control group. Sick euthyroid syndrome was the commonest form of thyroid dysfunction (23%), followed by subclinical hypothyroidism (14%). Thyroid dysfunction increased with increasing severity of CKD but this was not statistically significant.
Conclusions: Thyroid dysfunction is highly prevalent in dialysis naive CKD patients. Further studies need to be carried out to determine risk factors and evaluate the impact of treatment in these patients following which a guideline for screening and management can be developed.

Published: February 2024

Background: This research aimed to study the clinical presentation of various sino nasal masses (SNM), to study the importance of Histopathological and microbiological investigations in making diagnosis of SNM and to study the correlation between clinical, radiological, histopathological, and microbiological findings of SNM.
Methods: In the present study 50 patients attending the ENT outpatient department with clinical evidence of nasal mass were selected based on inclusion and exclusion criteria. Patients were examined clinically and radiologically followed by surgical intervention. Histopathological and microbiological examination was done to make a definitive diagnosis.
Results: Majority of cases were from 21-40 years age group (66%) with male preponderance. Nasal obstruction was most common symptom 45 (90%) followed by nasal discharge 43(86%). On histopathology highest incidence was of inflammatory polyps 22 (44%) followed by allergic polyps 14(28%) and non-invasive fungal sinusitis (NIFS) 11 (22%) respectively. Microscopically in KOH, fungal elements, yeast and hyphae were seen in total 11 (22%) cases and with SDA, Aspergillus niger was seen in 7 (14%) cases, Candida albicans in 3 (6%) and both in 1 (2%) case. Correlation of provisional diagnosis with HPE was found to be highly significant.
Conclusions: It was observed that histopathological and microbiological examination is irreplaceable as both are the “GOLD STANDARD” for making a definitive diagnosis.

Published: February 2024

Background: Methylene tetra hydro folate reductase (MTHFR) gene polymorphism C677T (rs180113) and DNA methylation in promoter region of MTHFR gene may contribute to the development of coronary artery disease however the results have been inconsistent across studies with different populations, so the aim of our study is to explore the association of polymorphism in MTHFR gene and methylation in promoter region with coronary artery disease (CAD) and other risk factor (lipid profile, homocysteine, vitamin B12 and folic acid levels) leading to CAD in of north Indian population.
Methods: Total 100 CAD patients and 100 healthy controls were enrolled in the study. Genotyping of rs1801133 SNP (C677T) is done by PCR-RFLP and DNA methylation study in promoter region by methylation specific PCR. Lipid profile analysis by automated chemistry analyzers, serum homocysteine, folic acid and vitamin B12 was assayed by ELISA.
Results: As per our finding the T allele (OR=3.03, 95% CI=1.74-5.27) and hyper methylation in promoter region of MTHFR increases the odds of coronary artery disease, (OR=3.05, 95% CI=1.7-5.6). Study participants with CT and TT genotype had significantly higher homocysteine (Hcy) (p=0.001), lower folic acid level (p=0.0), and HDL levels (p<0.0001) than those with CC genotype. The study subjects with hyper methylated promoter region have a significantly high homocystenemia levels (p=0.001).
Conclusions: The TT genotype of the MTHFR C677T gene polymorphism and hyper methylation in promoter region of MTHFR, is associated with CAD and can be useful in identification of new biomarkers, development of preventive and therapeutic strategies for CAD.
