Role of lidocaine and its effect on postoperative outcomes in abdominal cholecystectomy.

OBJECTIVE: To investigate the role of pre- and intra-operative lidocaine infusion on post-operative pain management. METHODS: The interventional, prospective study was conducted from September 2019 to June 2020 at the Pakistan Ordnance Factories Hospital, Wah Cantt, Pakistan, and comprised patients aged 18-60 years undergoing elective cholecystectomy who were randomised into intervention group A and control group B. Group A was given a bolus dose of lidocaine hydrochloride 2 mg/kg in addition to the standard anaesthesia protocol, while group B was given continuous intravenous infusion of 0.9% normal saline along with the standard protocol. Blood samples for interleukins 6 and 8 were taken at baseline, and then at 2, 6 and 8 hours Post-operatively. Data was analysed using SPSS 23. RESULTS: Of the 40 patients, 20(50%) were in each of the two groups. There was a marked decrease in interleukins 6 and 8 levels group A compared to group B (p<0.05). Interleukin 8 level showed a marked decline compared to that of interleukin 6 (p<0.05). CONCLUSIONS: A decrease in interleukins 6 and 8 levels highlighted the anti-inflammatory role of lidocaine and resulted in a decrease in post-operative opioid consumption.

Osteopontin promoter polymorphisms and risk of urolithiasis: a candidate gene association and meta-analysis study.

BACKGROUND: Urolithiasis is a worldwide urological problem with significant contribution of genetic factors. Pakistan, which resides within the Afro-Asian stone belt, has a high reported prevalence (12%) of urolithiasis. Osteopontin (SPP1) is a urinary macromolecule with a suggested critical role in modulating renal stone formation, genetic polymorphisms of which may determine individual risk of developing urolithiasis. However, results of previous studies regarding SPP1 polymorphisms and susceptibility to urolithiasis have apparent inconsistencies with no data available for local population. METHODS: A total of 235 urolithiasis patients and 243 healthy controls, all of Pakistani ancestry, underwent genotyping for six SPP1 genetic polymorphisms in an effort to investigate potential association with urolithiasis using indigenous candidate gene association study design. Further, a comprehensive meta-analysis following a systematic literature search was also done to ascertain an evidence based account of any existent association regarding SPP1 promoter polymorphisms and risk of developing urolithiasis. RESULTS: Three SPP1 promoter polymorphisms, rs2853744:G > T, rs11730582:T > C and rs11439060:delG>G, were found to be significantly associated with risk of urolithiasis in indigenous genetic association study (OR = 3.14; p = 0.006, OR = 1.78; p = 0.006 and OR = 1.60; p = 0.012, respectively). We also observed a 1.68-fold positive association of a tri-allelic haplotype of these SPP1 promoter polymorphisms (G-C-dG) with risk of urolithiasis (OR = 1.68; p = 0.0079). However, no association was evident when data were stratified according to gender, age at first presentation, stone recurrence, stone multiplicity, parental consanguinity and family history of urolithiasis. The overall results from meta-analysis, which included 4 studies, suggested a significant association of SPP1 rs2853744:G > T polymorphism with susceptibility of urolithiasis (OR = 1.37; p = 0.004), but not for other SPP1 polymorphic variants analyzed. CONCLUSIONS: In conclusion, we report significant association of 3 SPP1 polymorphisms with urolithiasis for the first time from South Asia, however, this association persisted only for SPP1 rs2853744:G > T polymorphism after meta-analysis of pooled studies. Further studies with a larger sample size will be required to validate this association and assess any potential usefulness in diagnosis and prognosis of renal stone disease.

Validity of STONE Score in Clinical Prediction of Ureteral Stone Disease.

OBJECTIVE: To determine the external validity of STONE score for predicting the probability of ureteral stone in patients presenting in emergency department with suspicion of ureteral stones. METHODS: In this prospective validation study, a total of 134 patients aged above 18 years, and first time arrived in the emergency unit for treatment of flank pain and then referred for the CT scan for suspected ureteral stone in Sandeman Provincial Hospital, Quetta, from 10-June-2018 to 15-Oct-2019 were included. STONE score calculation was done before sending the patient to the CT scan, using the same protocol as defined by Moore et al. Based on STONE score patients classified into the low-risk group (0 to 5), moderate-risk group (5 to 9) and the high-risk group (10 to13). The AUC, sensitivity, specificity and test characteristics were calculated for STONE score. RESULTS: The mean age was 39.2± 11.2 years, there were 86 (64.17%) men and 48 (35.83%) women. there were 26.8% patients having low-risk score, 52.23% moderate-risk and 21.97% high-risk score. On receiver operating curve (ROC) the area under curve (AUC) of the stone score was 0.75 (95% CI, 0.67 to 0.83), the lower band of AUC 0.67 and upper band 0.83. In high risk STONE score the sensitivity of STONE score was 66.7% and specificity was 75.0%. CONCLUSION: Based on our study results, CT scan and ultrasonography are standard diagnostic tools for suspected ureterolithiasis but in emergency unit, use of STONE score to categorize the patient as low risk, moderate-risk and high-risk of ureteral stone can help the physician (clinician) to take decision either there is a need of further investigation or not.

Effect of paroxetine on intestinal motility in the presence of ondansetron.

Chemotherapy, radiotherapy, surgery and depression are the conditions that run in parallel fashions. All these conditions cause the release of an increased amount of serotonin in the body. Serotonin acts on these 5HT3 receptors and causes nausea and vomiting. Ondansetron acts by blocking serotonin from acting on the receptors and thus is useful in decreasing episodes of nausea and vomiting but when used concomitantly with SSRIs (selective serotonin reuptake inhibitors) as cancer patient also suffered from depression. This combination tends to decrease the efficacy of ondansetron. The present study was carried out to observe the modulatory role of ondansetron on ileal smooth muscle motility in vitro. Experiments were performed in four groups (n=6) and ileal smooth muscle activity was recorded on the power lab (USA). The effects of increasing concentrations of serotonin, ondansetron and paroxetine alone were observed. In the fourth group effects of paroxetine in the presence of fixed concentration (1ml) of ondansetron (10-6M) was observed. The maximum response obtained by serotonin served as a control for our study (100%). Paroxetine response on intestinal motility was completely blocked in the presence of ondansetron. Our findings hence, reinforce the hypothesis that paroxetine decreases the antiemetic activity of serotonin antagonist ondansetron, by super sensitization of serotonergic receptors resulting in an increased incidence of nausea and vomiting in cancer patient despite adequate antiemetic prophylaxis.

Gene panel sequencing identifies a likely monogenic cause in 7% of 235 Pakistani families with nephrolithiasis.

Nephrolithiasis (NL) affects 1 in 11 individuals worldwide and causes significant patient morbidity. We previously demonstrated a genetic cause of NL can be identified in 11-29% of pre-dominantly American and European stone formers. Pakistan, which resides within the Afro-Asian stone belt, has a high prevalence of nephrolithiasis (12%) as well as high rate of consanguinity (> 50%). We recruited 235 Pakistani subjects hospitalized for nephrolithiasis from five tertiary hospitals in the Punjab province of Pakistan. Subjects were surveyed for age of onset, NL recurrence, and family history. We conducted high-throughput exon sequencing of 30 NL disease genes and variant analysis to identify monogenic causative mutations in each subject. We detected likely causative mutations in 4 of 30 disease genes, yielding a likely molecular diagnosis in 7% (17 of 235) of NL families. Only 1 of 17 causative mutations was identified in an autosomal recessive disease gene. 10 of the 12 detected mutations were novel mutations (83%). SLC34A1 was most frequently mutated (12 of 17 solved families). We observed a higher frequency of causative mutations in subjects with a positive NL family history (13/109, 12%) versus those with a negative family history (4/120, 3%). Five missense SLC34A1 variants identified through genetic analysis demonstrated defective phosphate transport. We examined the monogenic causes of NL in a novel geographic cohort and most frequently identified dominant mutations in the sodium-phosphate transporter SLC34A1 with functional validation.

Paroxetine: An update of response on intestinal motility.

OBJECTIVE: To find out the possible effects of paroxetine on gastrointestinal smooth muscles in vitro as they can cause severe nausea and vomiting at the start of therapy which later settles down. METHODS: Power lab (USA) was used for recording the contractions of ileal smooth muscle of rabbits in response to acetylcholine, serotonin and paroxetine. RESULTS: The percent responses with acetylcholine, serotonin and paroxetine were 100, 158.7 and 6.45 percent respectively indicating that acetylcholine and serotonin causes an increase in contractility of isolated ileal smooth muscle in comparison to paroxetine which has a depressant effect on motility. CONCLUSIONS: Inability of paroxetine to enhance the serotonergic transmission in vitro causes a decrease in its qualitative response.

Ondansetron: A newer aspect of dose response relationship on ileal smooth muscles of rabbit.

There are several life threatening deadly diseases in our world but 'Cancer' out powers them all in recent years. Chemotherapy may be used on its own or an adjunct to other forms of therapy. Despite the advancement in cytotoxic drug therapy and supportive treatment almost 70% of patient suffer from chemotherapy induced nausea and vomiting (CINV). Ondansetron, a 5-HT(3) receptor antagonist has now become a gold standard in the treatment of chemotherapy induced nausea and vomiting. The central actions of ondansetron are well established but its peripheral actions are not well recognized. The aim of our study was to explore the peripheral actions of ondansetron. Experiments were performed in five groups (n=6) and ileal smooth muscles activity was recorded on power lab (USA). The effects of increasing concentrations of acetylcholine, serotonin & ondansetron alone was observed in first three groups. In the next two groups effects of acetylcholine and serotonin pretreated with fixed concentration (1ml) of ondansetron (10¯Ï– M)were studied. The maximum response obtained by acetylcholine served as a control for our study. Maximum response with acetylcholine was taken as 100% and with serotonin was 177 percent of control. Cumulative dose response curve with ondansetron was triphasic. At 10¯ψM it was 28.8%, whereas with 10¯ξM the amplitude decreased to 16.87%, it reached to plateau at 10¯Ï– M. Response of acetylcholine & serotonin was decreased to 57% and 78% respectively in the presence of fixed concentration of ondansetron (10¯Ï– M). Ondansetron reduces the acetylcholine and serotonin induced gastrointestinal motility. Our study has indicated that ondansetron apart from having central action also has marked peripheral actions that play an important role in CINV and may act as a partial agonist.

Development of improved estimators of finite population mean in simple random sampling with dual auxiliaries and its application to real world problems.

In general, the incorporation of supplementary information reduces the Mean Square Error (MSE) and, consequently, enhances the precision of estimating a population parameter. This improvement relies on the appropriate application of a suitable function, with careful consideration. This study introduces two innovative families of estimators for the finite population mean, both of which exhibit superior performance in scenarios involving dual auxiliary information in simple random sampling. Expressions up to the first-order approximation, for bias, and Mean Square Error were derived, and the conditions under which these proposed families surpassed the existing estimators. Our evaluation involved the use of both real and simulated data to compute the Mean Square Error and Percent Relative Efficiency (PRE) of the estimators. A comparative analysis revealed that under the specified conditions, both proposed families yielded more precise results.

Orchestration and Management of Adaptive IoT-centric Distributed Applications.

Current Internet of Things (IoT) devices provide a diverse range of functionalities, ranging from measurement and dissemination of sensory data observation, to computation services for real-time data stream processing. In extreme situations such as emergencies, a significant benefit of IoT devices is that they can help gain a more complete situational understanding of the environment. However, this requires the ability to utilize IoT resources while taking into account location, battery life, and other constraints of the underlying edge and IoT devices. A dynamic approach is proposed for orchestration and management of distributed workflow applications using services available in cloud data centers, deployed on servers, or IoT devices at the network edge. Our proposed approach is specifically designed for knowledge-driven business process workflows that are adaptive, interactive, evolvable and emergent. A comprehensive empirical evaluation shows that the proposed approach is effective and resilient to situational changes.

Nexus between FinTech, renewable energy resource consumption, and carbon emissions.

An increase in energy crises and environmental degradation has pushed countries to adopt more sustainable practices. In this situation, financial technology has played an important role to lower carbon emissions by integrating renewable energy resources that can help increase renewable energy resource consumption (REC) and lower carbon emissions (CE). To better understand this transmission mechanism, this study has collected a panel dataset of 26 Morgan Stanley Capital International (MSCI) developing countries for the 2011-2021 period. Furthermore, a proxy indicator for financial technology (FinTech) was developed by extracting relevant data from CrunchBase. Pooled ordinary least square and robust fixed effects technique was adopted to analyse the influence of FinTech on renewable energy and carbon emissions for robustness. Results of the study show that FinTech development promotes renewable energy resource consumption (REC) and discourages carbon emissions (CE), moreover, economic growth positively impacts, and carbon emissions (CE). This research emphasizes the importance of adopting financial technology as an important deterrent of further environmental damage. Additionally, in line with the results of this study, policymakers should design and implement an industrial policy which promotes sustainable economic growth which can pave the path for a circular economy model in the future.

Virulence of entomopathogenic fungi against fall armyworm, Spodoptera frugiperda (Lepidoptera: Noctuidae) under laboratory conditions.

Maize is an essential crop of China. The recent invasion of Spodoptera frugiperda, also known as fall armyworm (FAW), poses a danger to the country's ability to maintain a sustainable level of productivity from this core crop. Entomopathogenic fungi (EPF) Metarhizium anisopliae MA, Penicillium citrinum CTD-28 and CTD-2, Cladosporium sp. BM-8, Aspergillus sp. SE-25 and SE-5, Metarhizium sp. CA-7, and Syncephalastrum racemosum SR-23 were tested to determine their effectiveness in causing mortality in second instars, eggs, and neonate larvae. Metarhizium anisopliae MA, P. citrinum CTD-28, and Cladosporium sp. BM-8 caused the highest levels of egg mortality, with 86.0, 75.3, and 70.0%, respectively, followed by Penicillium sp. CTD-2 (60.0%). Additionally, M. anisopliae MA caused the highest neonatal mortality of 57.1%, followed by P. citrinum CTD-28 (40.7%). In addition, M. anisopliae MA, P. citrinum CTD-28, and Penicillium sp. CTD-2 decreased the feeding efficacy of second instar larvae of FAW by 77.8, 75.0, and 68.1%, respectively, followed by Cladosporium sp. BM-8 (59.7%). It is possible that EPF will play an important role as microbial agents against FAW after further research is conducted on the effectiveness of these EPF in the field.

Collaborative Business Process Fault Resolution in the Services Cloud.

The emergence of cloud and edge computing has enabled rapid development and deployment of Internet-centric distributed applications. There are many platforms and tools that can facilitate users to develop distributed business process (BP) applications by composing relevant service components in a plug and play manner. However, there is no guarantee that a BP application developed in this way is fault-free. In this paper, we formalize the problem of collaborative BP fault resolution which aims to utilize information from existing fault-free BPs that use similar services to resolve faults in a user developed BP. We present an approach based on association analysis of pairwise transformations between a faulty BP and existing BPs to identify the smallest possible set of transformations to resolve the fault(s) in the user developed BP. An extensive experimental evaluation over both synthetically generated faulty BPs and real BPs developed by users shows the effectiveness of our approach.

Evaluating The Protective Effects Of Lovastatin Against Doxorubicin Induced Cardiotoxicity In Balb-C Mice.

BACKGROUND: Doxorubicin is one of the most commonly used anti-cancer drugs that treat a large number of haematological and solid malignancies. Its usage in dose and duration is nevertheless restricted by dose related organ damage, particularly cardiotoxicity. Lovastatin is a commonly prescribed drug for hypercholesterolemia and possesses remarkable antioxidant potential. Our study was aimed at evaluating and comparing its cardioprotective effect in two pre-treatment schedules against doxorubicin-induced cardiac damage. METHODS: In this lab-based randomized controlled experiment, 40 BALB/c mice were randomly grouped into five groups (n=8). Group 1 served as control whereas Group 2 was given doxorubicin intraperitoneally at a dose of 10mg/kg. Group 3 received 10mg/kg of oral lovastatin for five days. Groups 4 and 5 were administered lovastatin for five and ten consecutive days correspondingly and doxorubicin was given on 3rd and 8th experimental days of these groups. RESULTS: Doxorubicin caused a significant rise in cardiac enzymes; Creatine kinase MB (CK-MB) and Lactate Dehydrogenase (LDH) (p value ≤0.0001) whereas cardiac histological alterations were ranked as moderate. The damage was significantly attenuated by lovastatin in the ten-day study design with a p-value of ≤0.001 for both LDH and CK-MB whereas a slightly less efficient restoration was observed in the five-day design with a p value of ≤0.001 for LDH and 0.012 for CK-MB. Histological preservation in both pre-treatment schedules was in accordance with the biological markers. CONCLUSIONS: In doxorubicin-based regimens, pretreatment for at least seven days with an easily available and safe statin can effectively prevent its potentially life threatening cardiotoxicity.

The influence of green finance availability to retailers on purchase intention: a consumer perspective with the moderating role of consciousness.

As the global warming crisis is increasing daily, it is crucial to find ways to reduce the carbon footprint generated by activities like the production, consumption, and distribution of goods and services. This empirical study has looked at one approach through which environment-friendly production and consumption can be encouraged. The developed model has studied the relationship between retailers' access to green finance and consumer purchase intention of green products by incorporating the role of environmental, status, and future consciousness. Theoretical foundations for this model have been taken from the theory of planned behaviour (TPB) and theory of reasoned action (TRA), which have extensively discussed the role of consciousness and societal norms while making purchase intentions. To gain insights about the purchasing behaviour of consumers, this study collected data from the Jiangsu province of China, where a non-probability convenience sampling technique was used to distribute a questionnaire to 400 respondents between February 2022 and August 2022. The collected data was analysed using Structural Equation Modeling (SEM) in SmartPLS in order to study the relationship between independent and dependent variables. Results of this study show that retailers' access to green finance positively impacts consumer purchase intention towards green products, and adding a consciousness perspective in the model strengthens this relationship. Moreover, the theory of planned behaviour and the theory of reasoned action were validated through this study, providing insights for policymakers on the importance of promoting green finance to influence green product purchase intention. Overall, this study shows that policymakers should give green financing to retailers and environmental and future awareness to consumers to encourage environment-friendly behaviour.

Sublethal and transgenerational effects of synthetic insecticides on the biological parameters and functional response of Coccinella septempunctata (Coleoptera: Coccinellidae) under laboratory conditions.

Synthetic insecticides have been an inevitable part of plant protection throughout the world. Sublethal effects of these chemicals on beneficial insect species are one of the contemporary issues these days. Using the age-stage, two-sex life table model, this study evaluated the sublethal and transgenerational effects of six synthetic insecticides (imidacloprid, thiamethoxam, lambda-cyhalothrin, cypermethrin, chlorpyrifos and profenofos) commonly applied to winter vegetables, on the fitness and predation of the seven-spotted ladybeetle, Coccinella septempunctata, which is an efficient predator of aphids worldwide. According to results, all insecticides at their sublethal doses (LC30) significantly suppressed the emergence of adults, adult weight, fertility and fecundity of the parental generation compared to control treatment. The larval stage was prolonged and oviposition, fecundity and total longevity of the adult beetles were decreased in unexposed progeny whose parents were exposed to sublethal doses of all insecticides. Moreover, the biological parameters of adults, including the intrinsic rate of increase (r), finite rate of increase (λ) and net reproductive rate (R 0) were significantly reduced when exposed to sublethal doses of insecticides. The predation rate of the F1 generation adults was also decreased after exposure to the sublethal doses of insecticides. However, chlorpyrifos, profenofos, lambda-cyhalothrin and cypermethrin exhibited more deleterious effects on the fitness and population parameters of beetles than imidacloprid and thiamethoxam.

Dietary replacement of soybean meal with black soldier fly larvae meal in juvenile Labeo rohita and Catla catla: Effects on growth, nutritional quality, oxidative stress biomarkers and disease resistance.

This experiment aimed to investigate the effects of partial substitution of crude protein from soybean meal (SBM) with black soldier fly (Hermetia illucens) larvae meal (BSFLM) in juvenile rohu (Labeo rohita) and catla (Catla catla). Four isonitrogenous diets (23% crude protein) were formulated to replace 0% (T0), 40% (T40), 80% (T80) and 100% (T100) crude protein from SBM with BSFLM. Triplicate groups of each species (10 fish per replicate) were fed in an eight week growth experiment. After final sampling (n = 20 fish per dietary group), the remaining fish were exposed to bacterial (Staphylococcus aureus) challenge (0.80 CFU/ml) for 15 days. Rohu fed with BSFLM substituted diets showed significantly higher growth and feed conversion ratio as compared to those in T0. Catla fed with BSFLM substituted diets showed slightly higher growth indices. The growth response of rohu to BSFLM substitution was better than that noted in catla in all groups. The chemical composition, amino acids and fatty acids profile, haematological and biochemical parameters, levels of liver function enzymes measured in T0, T40, T80 and T100 were similar between four dietary groups in both species. However, the maximum value of cholesterol and triglycerides were noted in T100 both in catla and rohu. The values of lauric acid, α-linolenic acid, decosahexanoic acid, n3:n6 fatty acids ratio progressively increased with dietary increase of BSFLM in both species. At end of the growth experiment, the levels of catalase, superoxide dismutase and lysozyme increased linearly with the inclusion of BSFLM in both species while malondialdehyde showed similar values between different groups. However, catalase, and superoxide dismutase increased (T0

Bioassays of Beauveria bassiana Isolates against the Fall Armyworm, Spodoptera frugiperda.

The control of Spodoptera frugiperda, the key invasive pest of maize, is a serious concern due to its biology and the current global restriction on applying synthetic pesticides. Entomopathogenic fungi are considered to be a potential biological control strategy. The pathogenicity of 12 isolates of Beauveria bassiana in the immature stages and feeding efficacy of S. frugiperda were evaluated. The B. bassiana isolates QB-3.45, QB-3.46 and QB-3.428 caused the highest egg mortality rates of 87.3, 82.7 and 79.3%, respectively, when applied at a concentration of 1 × 108 conidia/mL and measured at 7 days post-treatment. Neonate mortality rates of 45.6 to 53.6% were observed with the same isolates. The B. bassiana isolates caused significant cumulative mortality rates ranging from 71.3 to 93.3% at 14 days post-treatment and reduced larval feeding efficacy from 69.4 to 77.8% at 48 h post-treatment. This study supports using the effective B. bassiana isolates as a biological control agent against S. frugiperda. The significant mortality of the eggs and neonatal larvae and the reduction in the feeding efficacy of the second instar larvae of the S. frugiperda that were treated with isolates of B. bassiana supports the application of entomopathogenic fungi as a biocontrol agent for the effective control of the S. frugiperda population.

Economic Boom and Busts Lead to Human Capital Changes? Evidence From Health Expenditure Changes in Emerging Economies.

This paper assesses data from 16 emerging economies between 2000-and 2020 to assess the relationship between business cycles and healthcare expenditure alongside other control variables. Using the Gaussian mixture model, this study analyses the relationship between healthcare spending and business cycles, urbanization, population age, environmental quality, and the gender ratio. The paper finds that there exists a counter-cyclical relationship between economic booms/recessions and healthcare expenditure such that spending decreases during booms and goes up during recessions. The study also finds evidence that environmental quality plays a vital role in influencing healthcare expenditure.

China's Jinshan Yinshan sustainability evolutionary game equilibrium research under government and enterprises resource constraint dilemma.

This paper is based on analyzing the process of green innovation inspiration and green innovation compensation effect after the implementation of environmental regulations by the Chinese Government. This paper tests the hypothesis using the evolutionary game model and studies the underlying behavioral characteristics of the government, enterprises, and the relevant influencing factors. These influencing factors further aid in examining the evolution law applicable on both sides, which are aligned with the dynamic replication equation and evolutionary equilibrium states under different situations. The key variables used in this study include the concentration of government's environmental regulation, the cost of the regulations, economic penalties, enterprise's green innovation-related income, expenditures, and the enterprise's performance appraisal. Moreover, the results of this study reflect the system stability and equilibrium strategy on the proportion of retained earnings spent by enterprises on green innovation activities and the Government's strict environmental regulations. In the process of game strategy selection between the government and enterprises, the net income and weight of eco-efficiency indicators of the enterprises actively carrying out green innovation activities play a decisive role. Moreover, there should be reduced weight of economic benefits and increase the economic sanctions and innovation subsidies of enterprise pollution behaviors. Furthermore, reduced cost of regulations and innovation expenditures help guide enterprises to rationally allocate superior resources to enhance green enterprise innovation and take the level of innovation to the point that it achieves a win-win green sustainable development of economic performance and environmental performance.
