Concomitant use of pre-emptive analgesia with local and general anesthesia in rat uterine pain surgical model.

Preemptive analgesia is used for postoperative pain management, providing pain relief with few adverse effects. In this study, the effect of a preemptive regime on rat behavior and c-fos expression in the spinal cord of the uterine surgical pain model was evaluated. It was a lab-based experimental study in which 60 female Sprague-Dawley rats; eight to 10 weeks old, weighing 150-300 gm were used. The rats were divided into two main groups: (i) superficial pain group (SG) (with skin incision only), (ii) deep pain group (with skin and uterine incisions). Each group was further divided into three subgroups based on the type of preemptive analgesia administered i.e., "tramadol, buprenorphine, and saline subgroups." Pain behavior was evaluated using the "Rat Grimace Scale" (RGS) at 2, 4, 6, 9 and 24 h post-surgery. Additionally, c-fos immunohistochemistry was performed on sections from spinal dorsal horn (T12-L2), and its expression was evaluated using optical density and mean cell count 2 hours postoperatively. Significant reduction in the RGS was noted in both the superficial and deep pain groups within the tramadol and buprenorphine subgroups when compared to the saline subgroup (p ≤ .05). There was a significant decrease in c-fos expression both in terms of number of c-fos positive cells and the optical density across the superficial laminae and lamina X of the spinal dorsal horn in both SD and DG (p ≤ .05). In contrast, the saline group exhibited c-fos expression primarily in laminae I-II and III-IV for both superficial and deep pain groups and lamina X in the deep pain group only (p ≤ .05). Hence, a preemptive regimen results in significant suppression of both superficial and deep components of pain transmission. These findings provide compelling evidence of the analgesic efficacy of preemptive treatment in alleviating pain response associated with uterine surgery.

Cyberattack patterns in blockchain-based communication networks for distributed renewable energy systems: A study on big datasets.

Blockchain-based reliable, resilient, and secure communication for Distributed Energy Resources (DERs) is essential in Smart Grid (SG). The Solana blockchain, due to its high stability, scalability, and throughput, along with low latency, is envisioned to enhance the reliability, resilience, and security of DERs in SGs. This paper presents big datasets focusing on SQL Injection, Spoofing, and Man-in-the-Middle (MitM) cyberattacks, which have been collected from Solana blockchain-based Industrial Wireless Sensor Networks (IWSNs) for events monitoring and control in DERs. The datasets provided include both raw (unprocessed) and refined (processed) data, which highlight distinct trends in cyberattacks in DERs. These distinctive patterns demonstrate problems like superfluous mass data generation, transmitting invalid packets, sending deceptive data packets, heavily using network bandwidth, rerouting, causing memory overflow, overheads, and creating high latency. These issues result in ineffective real-time events monitoring and control of DERs in SGs. The thorough nature of these datasets is expected to play a crucial role in identifying and mitigating a wide range of cyberattacks across different smart grid applications.

Rad Path in a Flash: Creation of the First AMSER Sponsored Digital Flashcard Deck and a Review of Digital Flashcard Use among? Medical Students.

RATIONALE AND OBJECTIVES: Digital flashcards are an increasingly popular study method for medical students today. The purpose of this study is to assess students' opinions on digital flashcards and to evaluate the need for radiology-focused digital flashcards. We created the first official Radiology-Pathology (Rad-Path) Correlation course digital flashcard deck sponsored by the Alliance of Medical Student Educators in Radiology (AMSER), and evaluated its effectiveness in increasing medical students' confidence levels of understanding Rad-Path concepts. MATERIALS AND METHODS: A 16-question survey was developed and publicly shared with medical students to assess the need for a high-quality radiology deck. In addition, students who trialed the AMSER Rad-Path Anki deck were assessed on their confidence of radiology pathology concepts prior to and after using these digital flashcards. RESULTS: 185 survey responses were received for the first survey about digital flashcard use. Overall, 87.6% of medical student respondents had used digital flashcards during medical school, and 33.5% had used digital flashcards to study radiology topics specifically. 67.6% of respondents stated they would use a digital flashcard deck if sponsored by an academic radiology society. Regarding the survey of the students who used the AMSER Rad-Path flashcards, 31 responses were received in the pre- and follow-up survey. Mean confidence in understanding the radiology pathology learning objectives increased when the Rad-Path Anki deck was utilized, and students rated the flashcards favorably. CONCLUSION: Students reported a high use of digital flashcards for studying topics in medical school. We identified a perceived need in students for a series of high-quality digital flashcards covering radiology topics. We created the first deck of AMSER Rad-Path flashcards which was well received by the medical students.

Neurofeedback Recuperates Cognitive Functions in Children with Autism Spectrum Disorders (ASD).

Autism spectrum disorder (ASD) is a neurodevelopmental disorder characterized by impaired social interaction, verbal and nonverbal communication, and behaviors or interests. Besides behavioral, psychopharmacological and biomedical interventions there is increasing evidence of non-invasive treatments like neurofeedback (NFB) that can improve brain activity. In this study, we have investigated whether NFB can improve cognitive functions in children with ASD. Thirty-five children with ASD (7-17 years) were selected by purposive sampling. The subjects underwent 30 sessions of NFB training for 20 min over 10 weeks' period. Psychometric tests i.e. Childhood Autism Rating Scale (CARS), IQ scoring and Reward sensitivity tests were administered at baseline. Pre and post NFB intervention assessment of executive functions, working memory and processing speed were done by NIH Toolbox Cognition Batteries. Friedman test revealed that children showed a statistically significant improvement in the NIH Tool Box cognitive assessments, including the Flankers Inhibitory Control and Attention Test (Pre-test = 3.63, Post-test = 5.22; p = 0.00), the Dimensional Change Card Sorting Test (Pre-test = 2.88, Post-test = 3.26; p = 0.00), the Pattern Comparison Processing Speed Test (Pre-test = 6.00, Post-test = 11:00; p = 0.00) and the List Sorting Working Memory Test (Pre-test = 4.00, Post-test = 6:00; p = 0.00), and displayed a trend of improvement at 2-month follow-up (Flankers Inhibitory Control and Attention Test (Post-test = 5.11 ± 2.79, Follow-Up = 5.31 ± 2.67; p = 0.21), the Dimensional Change Card Sorting Test (Post-test = 3.32 ± 2.37, Follow-Up = 3.67 ± 2.35; p = 0.054), the Pattern Comparison Processing Speed Test (Post-test = 13.69 ± 9.53, Follow-Up = 14.42 ± 10.23 p = 0.079) and the List Sorting Working Memory Test (Post-test = 6.17 ± 4.41, Follow-Up = 5.94 ± 4.03; p = 0.334). Our findings suggest NFB intervention for 10 weeks produce improvement in executive functions (Inhibitory Control and Attention and Cognitive Flexibility), Processing Speed and Working Memory in ASD Children.

Monsoon flood risks in urban areas of Pakistan: A way forward for risk reduction and adaptation planning.

Climate change poses a significant threat to sustainable urban development. Heavy rainfall has led to severe urban flooding, disrupting human life and causing widespread damage. This study aims to examine the impacts, preparedness, and adaptation strategies related to monsoon flooding in Lahore, Pakistan's second-most populous metropolitan area. Using Yamane's sampling method, a total of 370 samples were surveyed and analyzed using descriptive analysis and chi-square tests. The results indicate that houses and parks were the most commonly damaged properties, with common impacts including roof collapse, house fires, seepage, and wall dampness. These impacts not only caused physical damage but also disrupted basic amenities and damaged roads, resulting in significant socioeconomic costs. Despite these challenges, residents adopted a variety of adaptation strategies such as the use of temporary tarps, moving household appliances to upper floors, and shifting to tiled floors and wall paneling to mitigate damage. However, the study highlights the need for further measures to reduce flood risks and promote adaptation planning in order to effectively address the ongoing challenges posed by climate change and urban flooding.

The short-term impact of high energy nutritional supplements on energy balance in underweight primi-gravidae: A randomized controlled trial.

OBJECTIVE: To determine the impact of high-energy nutritional supplements on appetite, appetite regulators, energy intake and macronutrients level among underweight primigravidae. Methods: The single-blind randomised controlled trial was conducted from April 26, 2018, to August 10, 2019, in tertiary care hospitals of Khyber Pakhtunkhwa province of Pakistan, after approval from the ethics review committee of Khyber Medical University, Peshawar, and comprised underweight primigravidae who were randomly allocated to high energy nutritional supplement group A and placebo group B. Appetite questionnaires were filled and blood samples were obtained in fasting state, at 30, 60, 120, 210 and 270 minutes to measure blood glucose, insulin, peptide YY and cholecystokinin. Breakfast and lunch were served at 30 minutes and 210 minutes after supplementation, respectively. Data was analysed using SPSS 20. RESULTS: Of the 36 subjects, 19(52.8%) were in group A and 17(47.2%) were in group B. The overall mean age was 18.66 ± 2.5 years. Energy intake in group A was significantly higher than group B (p<0.001), and so were mean protein and fats (p<0.001). The subjective appetite perceptions for 'hunger' and 'desire to eat' were significantly lower (p<0.001) before lunch in group A. Plasma concentrations of appetite hormones corresponded to the appetite perceptions and were significantly higher in group A after breakfast and lunch for peptide YY, cholecystokinin and insulin compared to group B (p<0.001). CONCLUSIONS: High-energy nutritional supplement was found to have short-term suppressive effect on energy intake and appetite. Trial registration: ClinicalTrials.gov Identifier: ISRCTN 10088578.

The impact of brick kilns on environment and society: a bibliometric and thematic review.

Bricks have a long history of being utilized as a construction material across the globe. The production processes involved in the manufacture of bricks have a significant impact on the environment, human health, economy, and society. This study conducts a thematic and bibliometric analysis to provide an in-depth review of the effects of brick kilns on humans and the environment. The PRISMA framework was used to identify relevant articles from the Web of Science database, resulting in the selection and critical review of 348 articles. The bibliometric analysis included an evaluation of historical growth, keywords, citation and co-citation, organizations, and countries. The articles were published in 213 journals, written by 1396 authors from 670 institutions in 66 countries. Thematic analysis revealed that brick kilns have a negative impact on the environment, including soil damage, and cause health problems for kiln workers and animals. Modern slavery and societal issues also persist in developing countries. The current research is focused on finding alternative materials for brick manufacturing, improving industry energy efficiency, managing waste, and technological advancements, such as the implementation of the zigzag or Hoffmann kiln to reduce pollution. In developing countries, utilizing waste from other industries in brick production can effectively lower production costs. While developed countries have embraced advanced technologies for brick production, it is recommended that developing countries adopt awareness campaigns to encourage the upgrading of kilns to cleaner and more sustainable systems. Future research directions should aim to support brick kiln owners in adopting such systems.

Risk reduction via spatial and temporal visualization of road accidents: a way forward for emergency response optimization in developing countries.

To achieve an effective emergency response and road safety, this study aims to assist a semi-automated dynamic system to analyze and predict the spatial distribution and temporal pattern of road crashes. Kasur, an intermediate city of Pakistan, was selected and data including location, time and reasons of accidents for five years (2014-2018) was utilized. Radar charts, Getis-Ord Gi* statistic, Moran's I spatial auto-correlation, and time series indices were engaged to present temporal, spatial and spatial-temporal variation of accidents, using python-based tools and jupyter notebook. A dynamic user interface was created using Github and Tableau to visualize a real-time zoom-able spatiotemporal variation of accidents. The results explain that out of 12 months, October faces the peak while April sees the least of road accidents. 7am is the peak hour for accidents and the weekends record a significantly higher number of road accidents as compared to weekdays. The city core witnesses the major hotspot areas with huge cluster of accidents. The findings contribute towards a well-informed decision support system, the knowledge of spatial analytics and its application in road safety science, and the preparedness of the rescue agencies for rapid response to reduce the impacts of road accidents.

The effects of tobacco and cannabis use on semen and endocrine parameters in infertile males.

Substances such as tobacco and cannabis can negatively modulate seminal parameters and sex hormones and lead to fertility problems in males. The present study aimed to determine the effect of cigarettes, dipping tobacco, and cannabis on semen parameters and sex hormones in infertile males. A total of 160 infertile healthy participants (cigarette smokers n = 40, dipping tobacco users n = 40, cannabis users n = 40 and infertile controls n = 40) were included in the study. Fasting blood samples were collected from all the participants using the aseptic technique, and semen samples were collected by masturbation following sexual abstinence of 2-7 days. The levels of serum testosterone, follicle-stimulating hormone (FSH), and luteinizing hormone (LH) were determined using ELISA. The serum level of FSH was significantly higher in cannabis users relative to the control group (p = 0.043). A mild non-significant decrease in sperm count, serum LH and testosterone levels were observed in all drug users compared to controls. In conclusion, chronic use of tobacco and cannabis mildly modulates semen and hormonal parameters in infertile males.

A single-centre experience of His bundle pacing without electrophysiological mapping system: implant success rate, safety, pacing characteristics and one-year follow up.

Introduction: Despite the challenges related to His bundle pacing (HBP), recent data suggest an improved success rate with experience. As a non-university, non-electrophysiology specialised centre in Singapore, we report our experiences in HBP using pacing system analyser alone. Methods: Data of 28 consecutive patients who underwent HBP from August 2018 to February 2019 was retrospectively obtained. The clinical and technical outcomes of these patients were compared between two timeframes of three months each. Patients were followed up for 12 months. Results: Immediate technical success was achieved in 21 (75.0%) patients (mean age 73.3 ± 10.7 years, 47.6% female). The mean left ventricular ejection fraction was 53.9% ± 12.1%. The indications for HBP were atrioventricular block (n = 13, 61.9%), sinus node dysfunction (n = 7, 33.3%) and upgrade from implantable cardioverter-defibrillator to His-cardiac resynchronisation therapy (n = 1, 4.8%). No significant difference was observed in baseline characteristics between Timeframe 1 and Timeframe 2. Improvements pertaining to mean fluoroscopy time were achieved between the two timeframes. There was one HBP-related complication of lead displacement during Timeframe 1. All patients with successful HBP achieved non-selective His bundle (NSHB) capture, whereas only eight patients had selective His bundle (SHB) capture. NSHB and SHB capture thresholds remained stable at the 12-month follow-up. Conclusion: Permanent HBP is feasible and safe, even without the use of an electrophysiology recording system. This was successfully achieved in 75% of patients, with no adverse clinical outcomes during the follow-up period.

Treatment with combined resveratrol and myoinositol ameliorates endocrine, metabolic alterations and perceived stress response in women with PCOS: a double-blind randomized clinical trial.

PURPOSE: The present study aimed to assess whether treatment with combined resveratrol and myoinositol is more effective in ameliorating the altered parameters associated with PCOS when compared to the combined metformin and pioglitazone therapy. METHOD: One hundred and ten obese, oligo-anovulatory PCOS women, aged 20-35 years were randomly assigned into two treatment arms. Participants in arm-1 (n = 55), received combination of metformin and pioglitazone (500 mg and 15 mg, respectively), twice daily, while those in arm-2 (n = 55) received combination of resveratrol and myoinositol (1000 mg and 1000 mg, respectively) twice daily for 12 weeks. Evaluations performed at baseline were repeated after 3 months of therapy. The endocrine and metabolic derangements were assessed by measuring serum levels of testosterone, luteinizing hormone (LH), follicle-stimulating hormone (FSH), adiponectin and insulin using ELISA. Cohen's perceived stress scale (PSS) was employed as a subjective measure of stress. RESULTS: Pre-treatment PCOS women in both the arms (arm-1 and arm-2) had remarkably elevated serum testosterone and insulin concentrations, low serum adiponectin and high perceived stress response scores. The treatment reduced the altered endocrine indices in arm-2 (resveratrol and myoinositol) participants, manifested by statistically significant reduction in serum testosterone level (p = 0.001) and notably increased serum adiponectin level (p = 0.001). Interestingly, the hormonal profile, including serum LH and FSH levels also decreased (p < 0.001) along with a marked reduction in the ovarian volume (p = 0.001) in arm-2 participants. There was a significant reduction in weight (<0.001), BMI (p < 0.001) and an improvement in waist-hip ratio (p < 0.001) in arm-2 participants compared to arm-1 group. The PSS scores of the arm-2 subjects improved significantly (p < 0.001) whereas, the Ferrimen-Gallwey score was improved in both the arms (arm-1 and arm-2; p = 0.010 and 0.008 respectively) however, the change was highly significant in arm-2. Interestingly, the menstrual regularity was 81.4% in arm-2 while 18.2% in arm-1. We conclude that the therapeutic intervention with combined resveratrol and myoinositol is more effective in ameliorating altered endocrine, metabolic indices and stress burden and could be of clinical importance in high risk group of obese, oligo-anovulatory married PCOS affected women.

Efficacy Of Multiple Micronutrients Supplementation On Energy Intake, Calcium And Vitamin D Levels In Underweight Children.

Background: Under-nutrition is a major public health problem worldwide. Several studies have documented the effects of vitamin D and calcium supplements in healthy children and in children with bone abnormalities but the effects of multiple micronutrients supplementation in underweight children is limited in literature. Methods: In this randomized controlled trial 38 participants were recruited and divided into two groups of 19 subjects. On the first day of experimental trial, in fasting state 5cc blood samples were collected from all subjects followed by their anthropometric measurements, and serum levels of calcium and vitamin D. All subjects of one group were given Lipid-based nutritional supplement (LNS) and whereas the other group was given the placebo. After one month of compliance the same measurements were repeated and compared. Results: After one month of supplementation mid-upper arm circumference (p=0.005), weight (p<0.001), height (p=0.000), and BMI-Z score (p=0.002) the energy intake (p<0.001), were significantly increased in LNS as compared to Placebo. However, no improvement was observed in the plasma vitamin D (p=0.44) and calcium levels (p=0.46) of underweight children in both groups. Conclusion: Multi micronutrient supplementations are effective in improving anthropometry in the short duration of time. They also improve the energy intake of underweight children. However, no improvement is observed in levels of vitamin D and calcium in LNS group even after a one-month use.

Factors Influencing the Adoption of IoT for E-Learning in Higher Educational Institutes in Developing Countries.

The internet of things (IoT) is an emerging paradigm of educational applications and innovative technology in the current era. While capabilities are increasing day by day, there are still many limitations and challenges to utilizing these technologies within E-Learning in higher educational institutes (HEIs). The IoT is well-implemented in the United States of America (USA), United Kingdom (UK), Japan, and China but not in developing countries, including Saudi Arabia, Malaysia, Pakistan, Bangladesh, etc. Few studies have investigated the adoption of IoT in E-Learning within developing countries. Therefore, this research aims to examine the factors influencing IoT adoption for E-Learning to be utilized in HEIs. Further, an adoption model is proposed for IoT-based E-Learning in the contexts of developing countries and provides recommendations for enhancing the IoT adoption for E-Learning in HEIs. The IoT-based E-Learning model categorizes these influencing factors into four groups: individual, organizational, environmental, and technological. Influencing factors are compared along with a detailed description in order to determine which factors should be prioritized for efficient IoT-based E-Learning in HEIs. We identify the privacy (27%), infrastructure readiness (24%), financial constraints (24%), ease of use (20%), support of faculty (18%), interaction (15%), attitude (14%), and network and data security (14%), as the significant E-Learning influencing factors on IoT adoption in HEIs. These findings from the researcher's perspective will show that the national culture has a significant role in the individual, organizational, technological, and environmental behavior toward using new technology in developing countries.

Capturing spatial variability of factors affecting the water allocation plans-a geo-informatics approach for large irrigation schemes.

The livelihoods of poor people living in rural areas of Indus Basin Irrigation System (IBIS) of Pakistan depend largely on irrigated agriculture. Water duties in IBIS are mainly calculated based on crop-specific evapotranspiration. Recent studies show that ignoring the spatial variability of factors affecting the crop water requirements can affect the crop production. The objective of the current study is thus to identify the factors which can affect the water duties in IBIS, map these factors by GIS, and then develop the irrigation response units (IRUs), an area representing the unique combinations of factors affecting the gross irrigation requirements (GIR). The Lower Chenab Canal (LCC) irrigation scheme, the largest irrigation scheme of the IBIS, is selected as a case. Groundwater quality, groundwater levels, soil salinity, soil texture, and crop types are identified as the main factors for IRUs. GIS along with gamma design software GS + was used to delineate the IRUs in the large irrigation scheme. This resulted in a total of 84 IRUs in the large irrigation scheme based on similar biophysical factors. This study provided the empathy of suitable tactics to increase water management and productivity in LCC. It will be conceivable to investigate a whole irrigation canal command in parts (considering the field-level variations) and to give definite tactics for management.

Micronutrient status and energy intake in moderate acute malnourished children after intake of high Energy nutritional supplements for four weeks: a randomized controlled study.

BACKGROUND: Undernutrition including micronutrient deficiency results in adverse health-related outcomes in children of low-medium income countries. This study aims to explore the effect of four weeks of Lipid-based nutritional supplement (LNS) on energy intake, anthropometry and micronutrient status in moderate acute malnourished children. METHODS: Thirty-four children with mean age 7.08±1.47 years and a BMI Z score between -2 and -3 SDS were randomized into LNS and Placebo groups in a single blind randomized control trial. Energy intake, fasting blood samples, and anthropometric measurements were obtained prior to and after four weeks of LNS (535 kcal) or Placebo (92kcal) supplementation in addition to their habitual dietary intake. RESULTS: During four weeks of supplementation, energy intake (kcal) [(611±155) to (987±224), p<0.001)], weight (kg) [(17.5±2.83) to (18.1±3.24), p< 0.001], mid-upper arm circumference (cm) [(14.8±0.91) to (15.1±0.84), p=0.005)] and BMI (kg/m2) [(12.9±0.33) to (13.3±0.45), p=0.002] was significantly improved in the LNS group compared to Placebo. A significant increase in hemoglobin (g/ml) [(12.2±1.14) to (13.7±1.69), p<0.01] and iron levels (µg/dl) [(0.36±0.09) to (0.67±0.20), p<0.001] were observed in the LNS group. No significant differences were detected in the copper and zinc levels. CONCLUSIONS: Lipid-based nutritional supplement is effective in improving energy intake, nutritional outcomes and iron but not copper and zinc. The trial was registered at www.isrctn.com under reference: ISRCTN147181521.

Relationship Of Serum Adiponectin Levels With Glycaemic Status In Pregnant Women.

BACKGROUND: Adiponectin plays an important role in glucose metabolism and released in response to insulin. It helps to decrease glucose levels and insulin resistance; however, this relation is not been studied in pregnant ladies. Objective was to determine serum adiponectin level and glycaemic status in pregnant women belonging to Peshawar, Khyber Pakhtunkhwa (KPK) and to find any possible relationship between them. METHODS: Hundred pregnant women with gestational diabetes mellitus (GDM) and 100 healthy pregnant women without GDM were randomly selected in a cross-sectional study. After an overnight fast, their blood samples were taken for determination of serum adiponectin, glycosylated haemoglobin (HbA1c) and fasting blood glucose (FBG). The relationship of adiponectin with glycaemic status was determined with Pearson Correlations coefficient (r). RESULTS: Pregnant women with GDM when compared to healthy pregnant women showed significantly low levels of serum adiponectin (µg/mL) (2.2±0.2 vs. 11.25±4.8, p<0.05) and significantly high level of FBG (mg/dl) (182.7±64.2 vs. 93.6±5.9, p<0.05) and HbA1c (%) (7.4±0.1 vs. 5.4±0.1, p<0.05). Serum adiponectin level showed a statistically significant negative correlation with FBG (r = -0.203, p=0.042) and HbA1c (r = -0.744, p=0.000) in pregnant women with GDM. CONCLUSIONS: Serum adiponectin concentration is markedly decreased in pregnant women with GDM which concludes that Hypoadiponectinemia is related with deranged (elevated) glycaemic status in pregnancy. Moreover, adiponectin is associated negatively with FBG and HbA1c in the studied population.

Modelling soil salinity effects on salt water uptake and crop growth using a modified denitrification-decomposition model: A phytoremediation approach.

Soil salinization is a widespread problem affecting global food production. Phytoremediation is emerging as a viable and cost-effective technology to reclaim salt-affected soil. However, its efficiency is not clear due to the uncertainty of plant responses in saline soils. The main objective of this paper is to propose a phytoremediation dynamic model (PDM) for salt-affected soil within the process-based biogeochemical denitrification-decomposition (DNDC) model. The PDM represents two salinity processes of phytoremediation: plant salt uptake and salt-affected biomass growth. The salt-soil-plant interaction is simulated as a coupled mass balance equation of water and salt plant uptake. The salt extraction ability by plant is a combination of salt uptake efficiency (F) and transpiration rate. For water filled pore space (WFPS), the statistical measures RMSE, MAE, and R2 during the calibration period are 2.57, 2.14, and 0.49, and they are 2.67, 2.34, and 0.56 during the validation period, respectively. For soil salinity, RMSE, MAE, and R2 during the calibration period are 0.02, 0.02, and 0.92, and 0.06, 0.04, and 0.68 during the validation period, respectively, which are reasonably good for further scenario analysis. Over the four years, cumulative salt uptake varied based on weather conditions. At the optimal salt uptake efficiency (F = 20), cumulative salt uptake from soil was 16-90% for alfalfa, 11-70% for barley, and 10-80% for spring wheat. While at the lowest salt uptake efficiency (F = 40), cumulative salt uptake was nearly zero for all crops. Although barley has the highest peak transpiration flux, alfalfa and spring wheat have greater cumulative salt uptake because their peak transpiration fluxes occurred more frequently than in barley. For salt-tolerant crops biomass growth depends on their threshold soil salinity which determines their ability to take up salt without affecting biomass growth. In order to phytoremediate salt-affected soil, salt-tolerant crops having longer duration of crop physiological stages should be used, but their phytoremediation effectiveness will depend on weather conditions and the soil environment.

Auditory brainstem response: An overview of neurophysiological implications and clinical applications -A Narrative Review.

Evoked Potentials are electrical potentials that occur in a group of neurons in response to stimulation of a sensory organ which can be recorded by surface electrodes. Testing evoked potentials is useful in assessing the integrity of neuronal pathways both at sensory and motor levels of neural control. Early auditory evoked potentials include cochlear and brainstem auditory-evoked potentials, popularly known as electrocochleogram, and auditory brainstem response. Evoked potential audiometry is a neurophysiogical test to assess auditory pathway function in response to auditory stimuli. Auditory brainstem response mainly assesses brainstem functions and integrity. These evoked potentials are widely used for assessment of the cochlear functions, auditory nerve and the brainstem. Most common indications for auditory evoked potentials include routine newborn hearing screening for auditory pathway deficits, detecting retrocochlear pathologies, intraoperative and intensive care monitoring, frequency-related measurement of auditory sensitivity and for diagnosing some demyelinating disorders in initial stages. The current narrative review was planned to highlight auditory brainstem response recording's basic principles, uses and methods of interpretation in health and disease phases.
