A comparative study of tapentadol versus tramadol in the treatment of low back pain

Background: Nontraumatic musculoskeletal disorders are the main reason for presentation to the emergency department with Rachialgia being the most common reason to request medical assessment among them. Methods: This was a prospective, randomized, parallel group open labelled study conducted in a district level tertiary care hospital attached to a medical teaching institute. Patients were randomized into two groups. Group I (63 patients) received tablet tramadol 50 mg twice daily orally and group II (63 patients) received tablet tapentadol 50 mg twice daily orally.Results: The mean age of the patients of group I was 40.6±9.6 years and in the group II was 42.7±10.6 years. A total of 61 males participated in the study of which 31 males were enrolled in group I and 30 in group II while 65 females participated in the study of which 32 females were enrolled in group I and 33 in group II. The mean reduction of pain intensity VAS score at the end of 4 weeks from baseline in group I and group II were 34.57 and 37.55 respectively. The difference in the mean reduction of pain intensity VAS between the two groups was not statistically significant.Conclusions: We conclude that both the drugs show significant reduction in the pain intensity in moderate to severe CLBP patients. Tapentadol is as efficacious as tramadol in moderate to severe CLBP. However, tapentadol is better tolerated than tramadol

Synthesis, Spectral Characterization, and Antiproliferative Studies of Mixed Ligand Titanium Complexes of Adamantylamine

Titanium complexes have been synthesized by the reaction between titanium tetrachloride (TiCl4), respective bidentate ligand [4,4′ -dimethoxy-2,2′ -bipyridine (bpome), 6,6′-dimethyl-2,2′-bipyridine (dpme), 1,2-diaminocyclohexane (dach), 1,10-phenanthroline (phen), and benzoylacetone (bzac)], and adamantylamine (ada) in 1 : 2 : 2 molar ratios, respectively. The structure of synthesized complexes was confirmed using elemental analysis, FTIR, UV-visible, 1H NMR, and mass spectrometry techniques. The nanocrystalline nature of complexes was confirmed by powder XRD study. The complexes were evaluated for cytotoxic potential in HeLa (cervical), C6 (glioma), and CHO (Chinese hamster ovarian) cell lines. The complex E was found to be more effective cytotoxic agent against HeLa cell line with an IC50 value of 4.06 µM. Furthermore, the effect of synthesized complexes was studied on different stages of the cell cycle in CHO cells. All complexes exhibited the dose dependent increase in cytotoxicity. The results have shown an increase in sub-G0 population with increase in concentration which is an indicative measure of apoptosis

Doxorubicin induced histomorphometric changes in testes of albino rat

Anticancer drugs like doxorubicin have been found to affect male gonads thereby leading to infertility. This study was conducted to evaluate the effects of doxorubicin over short, mid and long term on testes of male albino rats. Sixty male albino rats aged 6-8 weeks were taken for study. The rats were randomly divided into 3 groups of experimental (each group containing 10 rats) and 3 groups of control (each group containing 10 rats). The experimental groups were given a single dose of doxorubicin i.e. 10 mg/kg body weight intra-peritoneally and sacrificed after 3 different duration for each group (second week, eighth week and sixteenth week). All rats under 3 control groups were given a single intra-peritoneal dose of 2.5 ml/kg body weight normal saline and sacrificed with their respective experimental groups. Significant difference in diameters (p=0.029) and cross-sectional area (p=0.028) of seminiferous tubules was observed between short term experimental and short term control rats. For both between midterm experimental and midterm control group, and between long term experimental and long term control group, a significant difference in right testis weight (p<0.001 for both), left testis weight (p<0.001 for both), volume of testis (p<0.001 and p=0.038), diameter (p<0.001 for both) and area (p<0.001 for both) of seminiferous tubules was observed. As compared to short term experimental group, midterm experimental group and long term experimental group had significantly lower right testis weight (p<0.001 for both), left testis weight (p<0.001 for both), diameter of seminiferous tubule (p<0.001 for both) and cross-sectional area of seminiferous tubule (p<0.001 both). Cross-sections of the seminiferous tubules of all the control groups had normal architecture. However, there was progressive destruction of seminiferous tubules structure across the experimental groups. Doxorubicin has deleterious effect on seminiferous tubules of albino rat testis.Nepal Journal of Biotechnology. Dec. 2015 Vol. 3, No. 1: 10-1

Effect of seedling age, seeding density and nitrogen fertilizer on growth and grain yield of rice (Oryza sativa L.)

Rice (Oryza sativa L.) is first staple crop of Nepal. The national average yield of rice is less than its potential yield, for which poor agronomic management has been reported as the critical factor. Among various agro-management practices seedling age, seeding density and nitrogen rates significantly affect the growth and yield of rice. The lower seeding density produces the taller plant, more effective tiller, lower sterility and higher grain yield. On the other hand, seedling of older age from higher seeding density gives the lowest yield. Transplanting younger seedling with low seeding density and application of recommended dose of nitrogen gives a higher yield. This article summarizes various effects of seedling age, seeding density and nitrogen rates on plant height, number of effective tillers, number of filled grains, thousand grain weight and grain yield of rice. This information may be useful for maize growers and researchers

Preferences and Practices regarding Delivery Place: A community-based cross-sectional study in Agra city, Uttar Pradesh

Background: Understanding preferences and practices for delivery place among women would assist in better resource utilization for skilled attendants. Objectives: To study factors influencing women’s preference and practice regarding their place of delivery. Methods: A community based cross-sectional study was conducted in Agra from 1st October 2018 to 31st October 2020. Multi-stage random sampling was used. Data was collected using semi-structured interview schedule. Both bivariate and multivariate analysis was done. Result: Majority (72.67%) of women had preference for delivery at government hospital while 19.67% for private hospital and only 7.67% for home. In actual practice, 58.33% had delivered at government hospital and 32.33% delivered at private hospital while 9.33 % at home. On multiple-logistic regression analysis, parity found to have significant association with preference of delivery at government hospital. Preference for delivery in private hospital was found to be significant with OBC caste and in women whose husband has skilled/highly-skilled occupation. In actual practice, Government hospital as delivery place found to have significant association with parity and presence of ASHA. Private hospital as a delivery place found significant with literate mothers and parity. Conclusion: Majority had preferred and practiced institutional delivery, preferring government hospital over private hospital.  In actual practice, delivery at private hospital as well as home delivery out-numbered the preferred proportion

Effect of integrated watershed management on vegetation cover, soil organic carbon and soil fertility in mid-hills of Nepal

This research was objectively carried out to evaluate the effect of integrated management on watersheds. Thus, well managed and poorly managed watersheds were selected; where samples from three altitudinal ranges, four land use types and three consecutive soil depths were taken. Changes in vegetation cover was also analysed. The result showed an increase in vegetation cover by 27.82 % in well managed, and decrease in vegetation cover by 38.33% in poorly managed watershed from 1992 to 2015.  Soil organic carbon was found highest (43.57 t/ha) in shrublands of altitudinal range of 1700 -2000 m of well managed, and lowest (3.94 t/ha) in shrublands of below 1700m in poorly managed watershed. This paper summarises that the integrated watershed management is crucial for increasing organic carbon content at the watershed level, as a contribution to climate change mitigation.Keywords: Soil organic carbon, soil fertility indicators, watershed management, vegetation cover

Rapeseed-Mustard Breeding in India: Scenario, Achievements and Research Needs

Brassica spp., commonly known as rapeseed-mustard, plays a significant role in the Indian economy by providing edible oils, vegetables, condiments and animal feed. Globally, India holds second and third position in rapeseed-mustard area under cultivation and production, respectively. However, anthropogenically accelerated climate change thwarts yield potential of rapeseed-mustard by employing abiotic (drought, flood, temperature variation and salinity) and biotic (disease and insects) stresses. Various approaches such as molecular breeding, pre-breeding, −omics and biotechnological interventions have been used to develop varieties for improved yield and oil quality, climate resilient and resistance or tolerance to abiotic and biotic stresses. In this context, this chapter highlighted the different cytoplasmic male sterility (CMS) sources and their potential use for hybrid development. At the end, this chapter also enlisted salient achievement by the government and non-government institutes and briefly described the future perspective for improvement of rapeseed-mustard in India

Evaluating air quality and criteria pollutants prediction disparities by data mining along a stretch of urban-rural agglomeration includes coal-mine belts and thermal power plants

Air pollution has become a threat to human life around the world since researchers have demonstrated several effects of air pollution to the environment, climate, and society. The proposed research was organized in terms of National Air Quality Index (NAQI) and air pollutants prediction using data mining algorithms for particular timeframe dataset (01 January 2019, to 01 June 2021) in the industrial eastern coastal state of India. Over half of the study period, concentrations of PM2.5, PM10 and CO were several times higher than the NAQI standard limit. NAQI, in terms of consistency and frequency analysis, revealed that moderate level (ranges 101–200) has the maximum frequency of occurrence (26–158 days), and consistency was 36%–73% throughout the study period. The satisfactory level NAQI (ranges 51–100) frequency occurrence was 4–43 days with a consistency of 13%–67%. Poor to very poor level of air quality was found 13–50 days of the year, with a consistency of 9%–25%. Random Forest (RF), Support Vector Machine (SVM), Bagged Multivariate Adaptive Regression Splines (MARS) and Bayesian Regularized Neural Networks (BRNN) are the data mining algorithms, that showed higher efficiency for the prediction of PM2.5, PM10, NO2 and SO2 except for CO and O3 at Talcher and CO at Brajrajnagar. The Root Mean Square Error (RMSE) between observed and predicted values of PM2.5 (ranges 12.40–17.90) and correlation coefficient (r) (ranges 0.83–0.92) for training and testing data indicate about slightly better prediction of PM2.5 by RF, SVM, bagged MARS, and BRNN models at Talcher in comparison to PM2.5 RMSE (ranges 13.06–21.66) and r (ranges 0.64–0.91) at Brajrajnagar. However, PM10 (RMSE: 25.80–43.41; r: 0.57–0.90), NO2 (RMSE: 3.00–4.95; r: 0.42–0.88) and SO2 (RMSE: 2.78–5.46; r: 0.31–0.88) at Brajrajnagar are better than PM10 (RMSE: 35.40–55.33; r: 0.68–0.91), NO2 (RMSE: 4.99–9.11; r: 0.48–0.92), and SO2 (RMSE: 4.91–9.47; r: 0.20–0.93) between observed and predicted values of training and testing data at Talcher using RF, SVM, bagged MARS and BRNN models, respectively. Taylor plots demonstrated that these algorithms showed promising accuracy for predicting air quality. The findings will help scientific community and policymakers to understand the distribution of air pollutants to strategize reduction in air pollution and enhance air quality in the study region
