Prevalence and factors associated with digital addiction among students taking university entrance tests: a GIS-based study.

BACKGROUND: The surge in digital media consumption, coupled with the ensuing consequences of digital addiction, has witnessed a rapid increase, particularly after the initiation of the COVID-19 pandemic. Despite some studies exploring specific technological addictions, such as internet or social media addiction, in Bangladesh, there is a noticeable gap in research focusing on digital addiction in a broader context. Thus, this study aims to investigate digital addiction among students taking the university entrance test, examining its prevalence, contributing factors, and geographical distribution using GIS techniques. METHODS: Data from a cross-sectional survey were collected from a total of 2,157 students who were taking the university entrance test at Jahangirnagar University, Bangladesh. A convenience sampling method was applied for data collection using a structured questionnaire. Statistical analyses were performed with SPSS 25 Version and AMOS 23 Version, whereas ArcGIS 10.8 Version was used for the geographical distribution of digital addiction. RESULTS: The prevalence of digital addiction was 33.1% (mean score: 16.05 ± 5.58). Those students who are attempting the test for a second time were more likely to be addicted (42.7% vs. 39.1%), but the difference was not statistically significant. Besides, the potential factors predicted for digital addiction were student status, satisfaction with previous mock tests, average monthly expenditure during the admission test preparation, and depression. No significant difference was found between digital addiction and districts. However, digital addiction was higher in the districts of Manikganj, Rajbari, Shariatpur, and Chittagong Hill Tract areas, including Rangamati, and Bandarban. CONCLUSIONS: The study emphasizes the pressing need for collaborative efforts involving educational policymakers, institutions, and parents to address the growing digital addiction among university-bound students. The recommendations focus on promoting alternative activities, enhancing digital literacy, and imposing restrictions on digital device use, which are crucial steps toward fostering a healthier digital environment and balanced relationship with technology for students.

Structural dynamics and anti-biofilm screening of novel imidazole derivative to explore their anti-biofilm inhibition mechanism against Pseudomonas Aeruginosa.

The biofilm formation is still prevalent mechanism of developing the drug resistance in the Pseudomonas aeruginosa, gram-negative bacteria, known for its major role in nosocomial, ventilator-associated pneumonia (VAP), lung infections and catheter-associated urinary tract infections. As best of our knowledge, current study first time reports the most potent inhibitors of LasR, a transcriptional activator of biofilm and virulence regulating genes in, Pseudomonas aeruginosa LasR, utilizing newly functionalized imidazoles (5a-d), synthesized via 1,3-dipolar cycloaddition using click approach. The synthesized ligands were characterized through Mass Spectrometry and 1H NMR. The binding potency and mode of biding of ligands. Quantum Mechanical(QM) methods were utilized to investigate the electronic basis, HOMO/LUMO and dipole moment of the geometry of the ligands for their binding potency. Dynamics cross correlation matrix (DCCMs) and protein surface analysis were further utilized to explore the structural dynamics of the protein. Free energy of binding of ligands and protein were further estimated using Molecular Mechanical Energies with the Poisson-Boltzmann surface area (MMPBSA) method. Molecular Docking studies revealed significant negative binding energies (5a - 10.33, 5b -10.09, 5c - 10.11, and 5d -8.33 KJ/mol). HOMO/LUMO and potential energy surface map estimation showed the ligands(5a) with lower energy gaps and larger dipole moments had relatively larger binding potency. The significant change in the structural dynamics of LasR protein due to complex formation with newlyfunctionalized imidazoles ligands. Hydrogen bond surface analysis followed by MMPBSA calculations of free energy of binding further complemented the Molecular docking revelations showing the specifically ligand (5a) having the relatively higher energy of binding(-65.22kj/mol).Communicated by Ramaswamy H.

Synthesis, biological evaluation and in silico investigations of benzotriazole derivatives as potential inhibitors of NIMA related kinase.

In the current study, a novel compound, bis(3-(2H-benzo[d][1,2,3]triazol-2-yl)-2-(prop-2-yn-1-yloxy)-5-(2,4,4-trimethylpentan-2-yl)phenyl)methane (TAJ1), has been synthesized by the reaction of 6,6'-methylenebis(2-(2H-benzo[d][1,2,3]triazol-2-yl)-4-(2,4,4-trimethylpentan-2-yl)phenol) (1), propargyl bromide (2) and potassium carbonate. Spectroscopic (FTIR, 1H-NMR, 13C-NMR) and single-crystal assays proved the structure of the synthesized sample. XRD analysis confirmed the structure of the synthesized compound, showing that it possesses two aromatic parts linked via a -CH2 carbon with a bond angle of 108.40°. The cell line activity reported a percent growth reduction for different cell types (HeLa cells, MCF-7 cells, and Vero cells) under various treatment conditions (TAJ1, cisplatin, and doxorubicin) after 24 hours and 48 hours. The percent growth reduction represents a decrease in cell growth compared to a control condition. Furthermore, density functional theory (DFT) calculations were utilized to examine the frontier molecular orbitals (FMOs) and overall chemical reactivity descriptors of TAJ1. The molecule's chemical reactivity and stability were assessed by determining the HOMO-LUMO energy gap. TAJ1 displayed a HOMO energy level of -0.224 eV, a LUMO energy level of -0.065 eV, and a HOMO-LUMO gap of 0.159 eV. Additionally, molecular docking analysis was performed to assess the binding affinities of TAJ1 with various proteins. The compound TAJ1 showed potent interactions with NEK2, exhibiting -10.5 kcal mol-1 binding energy. Although TAJ1 has demonstrated interactions with NEK7, NEK9, TP53, NF-KAPPA-B, and caspase-3 proteins, suggesting its potential as a therapeutic agent, it is important to evaluate the conformational stability of the protein-ligand complex. Hence, molecular dynamics simulations were conducted to assess this stability. To analyze the complex, root mean square deviation (RMSD) and root mean square fluctuation analyses were performed. The results of these analyses indicate that the top hits obtained from the virtual screening possess the ability to act as effective NEK2 inhibitors. Therefore, further investigation of the inhibitory potential of these identified compounds using in vitro and in vivo approaches is recommended.

Intrapelvic Kirschner wire Migration following Developmental Dysplasia of Hip Surgery and Laparoscopic Removal.

Salter innominate osteotomy remains the most commonly performed pelvic osteotomy for the Developmental Dysplasia of Hip in children after 18 months of age up to six years. Kirschner wire (K- wire) is used to fix the bone graft across the osteotomy site. Of the several complications of the pelvic osteotomy, K- wire migration into the pelvis is rare and only a few case reports are reported. We present a case of a 2-year-old girl with Right sided Developmental Dysplasia of Hip who underwent Femoral shortening and Salter innominate osteotomy, presented three months later with intrapelvic migration of k-wire. Paediatric Surgery consult was obtained and K-wire was removed laparoscopically without any complications successfully.

Morphoanatomical and Physiological Adaptations of Triticum aestivum L. against Allelopathic Extract of Trianthema portulacastrum L. (Horse purslane).

Weed infestation can be harmful to crop growth and cause severe losses in yield by absorbing nutrients and releasing inhibitory secondary metabolites and thus needs to be controlled for food security. The use of synthetic herbicides is one of the most widely applied methods, but its frequent usage is a serious threat to health and the environment and develops resistance in weeds. Allelopathy is an eco-friendly bio-control method, and Trianthema portulacastrum extracts are known to be effective against various weeds in the crop of Triticum aestivum (wheat), but their effect on the main crop (wheat) is still unknown. The pot experiment was carried out, and various concentrations (30, 60, and 100%) of root and shoot extracts of T. portulacastrum and a synthetic herbicide (Metafin Super) along with control (distilled water) were applied to the wheat plants. Various morphological, physiological, and anatomical parameters were recorded under natural conditions. The objective of this study was to explore the allelopathic impact of T. portulacastrum compared to the synthetic herbicide on the growth of wheat. This study displayed that various growth characteristics of wheat were significantly affected at p ≤ 0.05 by root and shoot water extracts of T. portulacastrum but were less inhibitory as compared to the synthetic herbicide. This inhibition of the growth of wheat was coupled with a significant increase in total free amino acids, K ions, CAT (catalase), proline, epidermal and cortical thickness, and abaxial stomatal density. In addition, a reduction in growth parameters was correlated with a decrease in photosynthetic pigments. This study revealed that the use of T. portulacastrum extracts could be safer than synthetic herbicides for wheat plants and would be beneficial to control weeds in a wheat field.

A Randomized Double-Blind Comparative Study of the Intubating Conditions and Hemodynamic Effects of Rocuronium and Succinylcholine in Pediatric Patients.

BACKGROUND: The incidence of unanticipated difficult airways is higher in pediatric age groups than in adults due to the different airway anatomy, difficulty in airway examination, and congenital malformations. Rocuronium bromide has a comparable onset time to succinylcholine at its proportionate dose. Hence, we compared rocuronium bromide with succinylcholine to assess intubating conditions and their side effects, if any. METHOD: A total of 200 pediatric patients of American Society of Anesthesiologists (ASA) grades I and II between one and 14 years of age of either sex posted for elective surgery were included in the study. After randomization, group R (n = 100) received 1.2 mg/kg rocuronium, and group S (n = 100) received 2 mg/kg succinylcholine intravenously. After confirming the mask ventilation, the study drugs were administered, and intubating conditions were assessed as excellent, good, poor, or impossible. Hemodynamic changes post-intubation were recorded as our secondary outcome. RESULT: Intubating conditions were excellent( 65%), good( 25%) and fair (10%) in patients of group R, while results in group S were excellent( 60%), good( 20%), fair (15%), and poor (5%) (p = 0.010). The heart rate was significantly increased post-intubation in group S, while there was no significant increase in systolic or diastolic blood pressure in either group. CONCLUSION: At a dose of 1.2 mg/kg body weight, rocuronium was a better alternative to succinylcholine for providing rapid intubating conditions and stable hemodynamics without associated adverse effects.

The Effect of Sepsis and Septic Shock on the Viscoelastic Properties of Clot Quality and Mass Using Thromboelastometry: A Prospective Observational Study.

Background: Sepsis is associated with wide variable coagulation abnormalities. Thromboelastography (TEG) effectively measures the viscoelastic properties of the clots. This study aims to illustrate the viscoelastic properties of clot quality and mass in sepsis and septic shock patients using TEG, as an effective tool over standard coagulation tests. Materials and methods: A single-center, prospective observational study was conducted. 50 patients each meeting the criteria for sepsis and septic shock, and a healthy group of 30 patients was included in the study. Blood samples were obtained and analyzed for standard coagulation tests, platelet count, fibrinogen, and TEG study. Results: A total of 130 patients were included. Septic shock patients had a higher sequential (sepsis-related) organ failure score. Prothrombin time (PT) and activated partial thromboplastin time (aPTT) were increased significantly as compared to the sepsis and control groups. TEG markers such as alpha angle, and maximum amplitude (MA) were significantly prolonged while reaction time (R time), was significantly shortened in the sepsis group as compared to the healthy group, suggestive of a hypercoagulable state in sepsis patients. While in septic shock patients, MA and Lysis Index 30 (LY 30) were significantly prolonged and, R time was significantly shortened compared to all other groups. Even though LY30 in sepsis patients was found to be within the normal range (p < 0.001), 18% of patients had prolonged LY30 indicating a hypercoagulable state with impaired fibrinolysis. Conclusion: Thromboelastography, as a point-of-care test combined with conventional coagulation tests can provide additional, clinically relevant information on coagulopathy, and outcome, and thus help guide treatment modality in sepsis and septic shock-induced coagulopathy.

Evaluating the effectiveness of Moringa oleifera leaf capsules in controlling glycemic and hypertension levels in type 2 diabetes patients.

Moringa oleifera (MO) phytochemicals and therapeutic properties improve hyperglycemia and treat type 2 diabetes. Thus, this study examined the effects of MO leaf capsules on blood glucose management in type 2 diabetic mellitus (T2DM) and hypertension and their safety. A prospective placebo-controlled experiment randomly assigned 24 patients to receive 3g and 6g of MO leaf capsules twice a day or a placebo for three months. Pre- and post-study lab and clinical outcomes were assessed. The placebo control group and 3g MO leaf showed a minor change, whereas 6g and control placebo showed a considerable drop in examined features. MO usage was safe. In T2DM patients, MO leaves lowered blood pressure, requiring further study. MO leaves may help T2DM patients manage blood pressure and blood sugar, according to the study. MO's therapeutic components need more research.

Toxicity and tolerance of nickel in sunflower (Helianthus annuus L.).

This study aimed at exploration of nickel (Ni) application (0, 10, 20, 30, and 40 mg L-1) on physiological and biochemical attributes of sunflower cultivars (Hysun-33 and SF-187) grown in sand culture. Results revealed a significant decrease in vegetative parameters in both sunflower cultivars by increasing Ni concentration, although low levels of Ni (10 mg L-1) improved growth attributes to some extent. Among photosynthetic attributes, 30 and 40 mg L-1 Ni application severely reduced the photosynthetic rate (A), stomatal conductance (gs), water use efficiency (WUE), and Ci/Ca ratio but improved the transpiration rate (E) in both sunflower cultivars. The same level of Ni application also reduced leaf water potential, osmotic potentials, and relative water contents but increased leaf turgor potential and membrane permeability. At low level (10 and 20 mg L-1), Ni improved the soluble proteins, while high Ni concentration decreased it. The opposite was true for total free amino acids and soluble sugars. To conclude, the high Ni concentration in various plant organs had a strong impact with the changes in vegetative growth, physiological and biochemical attributes. A positive correlation of growth, physiological, water relations, and gas exchange parameters at low levels of Ni and negative correlation at higher Ni level confirmed that the supplementation of low Ni levels greatly modulated studied attributes. Based on observed attributes, Hysun-33 showed high tolerance to Ni stress as compared to SF-187.

Nerium oleander could be used for sustainable management of traffic-borne elemental-enriched roadside soils.

Metal pollutants released from motor vehicles are deposited in roadside environments. Metals are non-biodegradable and biomagnify in the food chain causing significant health hazards at all levels of the ecosystem. Hence, management of contaminated roadside verges is critically important and should be kept in mind while planning specific management strategies of such areas. Native vegetation could help to decontaminate heavy metal polluted soils in the best sustainable way. Therefore, this study was designed to assess the potential of Nerium oleander to accumulate heavy metals commonly released by automobiles such as Pb, Cd, Ni, and Zn along with various C and N compounds from five different locations along a busy road in Punjab, Pakistan, during summer and winter seasons. N. oleander showed the ability to absorb C, N, and heavy metals Pb and Cd; the maximum concentration of Pb and Cd was 8.991 mg kg-1 and 0.599 mg kg-1, respectively. These pollutants negatively affected photosynthetic pigments, gas exchange attributes, soluble proteins, and free amino acids. But antioxidant activity of N. oleander was found to be increased in both seasons. The metal accumulation in the plant was higher in the summer though. We highly recommend that by growing N. oleander at roadside verges for decontamination of vehicular pollutants could lead to sustainable management of these corridors.

Efficiency of face mask ventilation before and after neuromuscular blockade: A randomised, double-blind controlled study.

Background and Aims: The traditional practice of administrating neuromuscular blocking drugs (NMBDs) after checking face mask ventilation is challenged repeatedly. This study compared the efficiency of face mask ventilation before and after administrating an NMBD in a patient with a normal airway. The secondary outcome measured was the grade of mask ventilation and tracheal intubating conditions. Methods: After ethical approval, patients (n = 120) in the age group of 18-65 years scheduled for elective surgery under general anaesthesia were randomly assigned into two groups. Group 1 received an NMBD before checking face mask ventilation. Group 2 received an NMBD after checking face mask ventilation. Lungs were ventilated for 180 s, during which expiratory tidal volume (Vte) was recorded as the primary outcome. Hans's grading for face mask ventilation was used to grade mask ventilation. The ease of intubation was assessed based on intubating conditions (ease of laryngoscopy, vocal cord movement, and limb movement). SPSS 20.0 software was used for statistical analysis. Results: For a total of 180 seconds of mask ventilation, the mean (standard deviation) Vte measured after apnoea was significantly higher in Group 1 versus Group 2 [471.9 (63.3) vs 434.8 (77.0) mL/breath, P = 0.004]. The intubating condition was either excellent or good in all patients. Conclusion: The administration of NMBDs resulted in a larger mask Vte and shorter intubation time.

Analysis of 1-Aroyl-3-[3-chloro-2-methylphenyl] Thiourea Hybrids as Potent Urease Inhibitors: Synthesis, Biochemical Evaluation and Computational Approach.

Urease is an amidohydrolase enzyme that is responsible for fatal morbidities in the human body, such as catheter encrustation, encephalopathy, peptic ulcers, hepatic coma, kidney stone formation, and many others. In recent years, scientists have devoted considerable efforts to the quest for efficient urease inhibitors. In the pharmaceutical chemistry, the thiourea skeleton plays a vital role. Thus, the present work focused on the development and discovery of novel urease inhibitors and reported the synthesis of a set of 1-aroyl-3-[3-chloro-2-methylphenyl] thiourea hybrids with aliphatic and aromatic side chains 4a-j. The compounds were characterized by different analytical techniques including FT-IR, 1H-NMR, and 13C-NMR, and were evaluated for in-vitro enzyme inhibitory activity against jack bean urease (JBU), where they were found to be potent anti-urease inhibitors and the inhibitory activity IC50 was found in the range of 0.0019 ± 0.0011 to 0.0532 ± 0.9951 µM as compared to the standard thiourea (IC50 = 4.7455 ± 0.0545 µM). Other studies included density functional theory (DFT), antioxidant radical scavenging assay, physicochemical properties (ADMET properties), molecular docking and molecular dynamics simulations. All compounds were found to be more active than the standard, with compound 4i exhibiting the greatest JBU enzyme inhibition (IC50 value of 0.0019 ± 0.0011 µM). The kinetics of enzyme inhibition revealed that compound 4i exhibited non-competitive inhibition with a Ki value of 0.0003 µM. The correlation between DFT experiments with a modest HOMO-LUMO energy gap and biological data was optimal. These recently identified urease enzyme inhibitors may serve as a starting point for future research and development.

Comparison of Palonosetron Versus Palonosetron and Dexamethasone for Prevention of Postoperative Nausea and Vomiting After Middle Ear Surgeries: A Randomized Controlled Study.

Background: Postoperative nausea and vomiting (PONV) are one of the common distressing conditions after anesthesia. The PONV are related to several potential risk factors are patient related, anesthesia related, and surgery related. In surgery-related risk, middle ear surgery is associated with a high incidence of PONV. Aims: This study aimed to compare the efficiency of palonosetron versus palonosetron with dexamethasone in the prevention of PONV in middle ear surgeries. Settings and Design: This was a prospective, randomized, double-blind study. Statistical Analysis: The data were presented as descriptive statistics for continuous variables and percentages for categorical variables and were subjected to Z-test/Chi-square test/Fisher's exact test. The value of P < 0.05 was considered statistically significant. Results: Demographic parts in comparison to age, duration of surgery, and duration of anesthesia were similar in both the groups. Our study showed that the incidence of PONV during 0-6 h was 38% (n = 19) in Group A and 12% (n = 6) in Group B and the incidence during 6-12 h postoperatively was 14% (n = 7) in Group A and 8% (n = 4) in Group B. During 12-24 h, the incidence was 8% (n = 4) and 6% (n = 3) in Group A and B, respectively. Hence, the difference of total early PONV in Group A was 60% (n = 30) and in Group B, it was 26% (n = 13) which was statistically significant (P < 0.03). Conclusions: The above result proves that palonosetron and dexamethasone group is superior in the prevention of PONV in middle ear surgery.

Comparison of percutaneous tracheostomy methods in ICU patients: Conventional anatomical landmark method versus ultrasonography method - A randomised controlled trial.

Background and Aims: Percutaneous dilational tracheostomy (PDT) is a common procedure in intensive care unit (ICU) patients requiring long-term mechanical ventilation. PDT has gradually replaced surgical tracheostomy because it is associated with minimal invasiveness, reduced bleeding and simplicity in technique.This study was conducted to compare ultrasound-guided PDT versus conventional tracheostomy in terms of duration of the procedure, number of passes and immediate peri-procedural complications. Methods: A total of 72 patients with clinical indications of tracheostomy were recruited. A total of 12 patients met the exclusion criteria. The remaining were randomly assigned into two groups of 30 each: Group A (Landmark) with traditional anatomical landmark and Group B (USG) with real-time ultrasound guidance. Puncture positions were recorded with bronchoscopy. Midline deviation was captured on a bronchoscopy image using a protractor. Data on procedural safety and efficacy were also collected. Results: Group B had significantly fewer cases of midline deviation (11.33 ± 9.51) in comparison to Group A (16.60 ± 12.31). Trials > 2 were equal to 11 in Group A and 2 in Group B. However, the duration of the procedure was higher in Group B (20.07 ± 3.25 min) as compared to Group A (15.20 ± 3.71 min). Peri-procedural and post-procedural complications were also higher in the Landmark group. Conclusion: Ultrasound-guided PDT showed superiority over landmark PDT in terms of less number of trials, midline puncture and fewer complications. However, it took a little longer to perform USG-guided PDT.

Does Health Crises Effect Tourism: Role of Financial Inclusion for Green Financial Development.

Tourism is impacted by all types of crises, no matter how big or small. Even though many studies have examined tourism crises, most focus on the number of tourists arriving and departing. As a result of this lack of information, The adaptive differences in tourist behavior caused by various crises are not well understood. When it comes to inbound tourism, the financial and health-related crisis can significantly impact the tourist profile of the country and its visitors' spending habits. The findings show that the health crisis has a significant positive impact on tourism. Moreover, COVID_deaths and COVID_confirm_cases decrease the international tourism in developed and developing countries. According to the study's findings, tourists' sensitivity to crises varies between short- and long-haul markets. The evidence shows that financial inclusion has a significant positive impact on various aspects of tourism development in China. Hence, this article offers numerous policy and practical suggestions for sustainable tourism management.

Proximate composition and spatio-temporal heterogeneity of phytochemicals in Agave sisalana Perrine (sisal) adapted in different agro-ecological zones of Punjab, Pakistan.

Exploring extractable phytochemicals from locally adapted sisal plant vegetation vary seasonally at different locations. This study elaborated proximate composition and phytochemical heterogeneity in sisal due to varying environmental conditions analyzed from five districts, i.e., Chakwal, Khushab, Rawalpindi, Faisalabad, and Layyah in Punjab, Pakistan. Extensive surveying and plant sampling across 2 years 2017-2018 and 2018-2019, during mid-spring, summer, autumn, and winter seasons were carried out for understanding the seasonal impact on sisal. The present study was designed in a randomized complete block design (RCBD) and analyzed considering seasonal, yearly, and locational impact. The spatial differences in phytochemicals concentration were strongly associated with environmental conditions prevailing in different seasons. Autumn season reflected saponins, tannins, and flavonoids in higher concentrations during 2018-2019 while steroids and terpenoids were higher during spring 2018-2019. Spatio-temporal variations in the proximate analysis were more apparent in different samples collected from different districts. Data recorded for the Khushab district and autumn season reflected the higher composition of a proximate analysis and phytochemical contents as compared to other seasons. Overall, the spatial differences in phytochemicals concentration were strongly associated with soils and environmental conditions prevailing in different seasons in selected districts.

Evaluation of Propofol-Sparing Effect of Intravenous Lignocaine in Patients Undergoing Daycare Upper Gastrointestinal Endoscopic Procedures.

Background Propofol is the most common sedative for endoscopies. Propofol alone may require larger doses for adequate level of sedation. Lignocaine is known for its anesthetic-sparing effect. We tested whether the addition of intravenous lignocaine to propofol-based sedation reduces its dose. Methods This prospective, randomized study was performed on 90 patients of 18 to 60 years of age, of either sex of the American Society of Anesthesiologists (ASA) Grade-I & II, and was divided into two groups. Group L + P received IV bolus of 1.5 mg/kg 2% lignocaine over 10 minutes followed by 1.5 mg/ kg/ h infusion and group NS + P- received the equivalent volumes of normal saline in bolus and infusion. Patients were induced with fentanyl (2 µg/kg) and propofol (1 mg/kg). To maintain an adequate sedation level, a supplemental bolus of 0.5 mg /kg propofol was administered. The outcomes recorded were the total and supplemental amount of propofol administered, as well as recovery time. Results The mean supplemental propofol for group L + P and group NS + P- 37.00 ± 29.93 and 58.67 ± 19.49 mg, respectively and mean total propofol consumption was 98.22 ± 34.00 mg and 131.11 ± 23.18 mg, respectively, (p < 0.001). Mean recovery time in group L + P was also shorter (5.22 ± 2.14 versus 9.96 ± 2.14). The incidence of adverse events like gag reflux, upper airway obstruction, pain on injection, and hypotension was significantly lower in group L + P (p < 0.05). Conclusion The addition of lignocaine to propofol-based sedation reduced the overall propofol requirement at the same time maintaining hemodynamic stability, spontaneous respiration, and early recovery.

Physiological, Biochemical and Defense System Responses of Roadside Vegetation to Auto-Exhaust Pollution.

This study determined the effects of traffic pollutants on plants (Nerium oleander and Ricinus communis) growing along Faisalabad to Okara (R-1) and Okara to Lahore (R-2) roads in Pakistan. The photosynthetic pigments, photosynthetic rate, transpiration rate and total soluble proteins of roadside vegetation were significantly lower than control plants (50 m away from road). The average decrease in photosynthetic rate of Nerium oleander and Ricinus communis was 33.90% and 27.94% along R-1 and 41.85% and 32.409% along R-2 road, respectively. The decreased photosynthesis in roadside flora resulted in higher water use efficiency and substomatal CO2 concentration. However, higher antioxidant activity and free amino acid contents were noted in roadside plants that might be due to their defensive response to traffic pollutants. N. oleander was more affected by traffic pollutants and R. communis showed more resistance. Thus, N. oleander could be used for biomonitoring and R. communis for phytoremediation of vehicular pollution.

USA carbon neutrality target: Evaluating the role of environmentally adjusted multifactor productivity growth in limiting carbon emissions.

One of the most vital strategies to achieve sustainable development is to target green growth, which is pollution adjusted output growth rate. Since green growth addresses both economic performance and environmental sustainability, it is necessary for sustainable development. To gauge the environmental impact of increased output, researchers use conventional measure of output growth. However, these measures are not adjusted for pollution and hence, do not reflect the true growth performance of the economy. For this purpose, this study aims to investigate the role of green growth in limiting carbon emissions in the USA for the period of 1990-2019. The authors further examine the role of globalization and renewable energy consumption in affecting CO2 emissions of USA. The results show that in the long run, green growth, output, renewable energies, and globalization are important factors in affecting CO2 emissions of USA. The results of frequency causality test show that there is unidirectional causal relationship from output renewable energy consumption, green growth, and globalization to CO2 emissions in the long run and medium run. This study suggests interesting policies for achieving targets of carbon neutrality. There is a dire need to take instant actions to control climate change and to mitigate greenhouse gases (GHGs). To achieve the target of carbon neutrality, a downward adjustment of economic growth is necessary, which will help the country to abate the pollution emissions.

China carbon neutrality target: Revisiting FDI-trade-innovation nexus with carbon emissions.

Since the Paris Agreement, countries around the globe have been striving to achieve their carbon neutrality targets. However, because China has one of the largest economies in the world, to achieve its targeted carbon neutrality, the roles of foreign direct investment (FDI), technological innovation (TI), and trade are crucial. Therefore, this study aims to introduce the level of trade, renewable energy consumption (REC), and FDI from the years 1995-2017 as new determinants in promoting a sustainable environment in China. The study employs advanced panel methods based on slope homogeneity and a cross-sectional dependence test. The results confirm a cointegration relationship for all models in this study, suggesting that gross domestic product and FDI positively affect carbon emissions. By contrast, foreign trade, REC, and TI are inversely associated with carbon emissions. Moreover, according to Chinese provincial data, the joint term for FDI with REC and TI is negatively associated with carbon emissions. The policy implications of this study suggest that to achieve sustainable FDI, TI should be encouraged to mitigate the pollution caused by FDI. There is a dire need to implement green practices and eco-friendly policies at a national scale.
