Prevalence of vitamin d deficiency in medical students

The prevalence of vitamin D deficiency has recently been recognized in different parts of the world, even affecting healthy populations. The deficiency of vitamin D can lead to rickets in children and osteomalacia in adults. Few studies have been done to evaluate the status of vitamin D in the medical community around the world. No studies have been done in Libya to evaluate the status of vitamin D in medical students. The aim of this study was to evaluate the prevalence of low level of vitamin D in among healthy Libyan medical students of first year in University of Tripoli, Tripoli. Prospective study was conducted on 100 medical students of first year in Faculty of Medicine with a mean age of 19.5 years, 38 males and 62 females. Blood samples were taken and investigated for different biochemical parameters including serum calcium, serum vitamin D and serum parathyroid hormone levels. Questionnaire containing different data was completed for each student including personal data (age, address, nationality, and other data related to vitamin D deficiency. The prevalence of vitamin D deficiency in all the participated students was 74% (58.7% in males and 83.8% in females), while 21% had vitamin D insufficiency (28% in males and 16.12% in females). Only 5% of the students that had normal vitamin D was males. The mean 25-hydroxy vitamin D level was 19.49 ± 8.56 ng/ml in males and 12.08 ± 6.70 ng/ml in female students. Statistical analysis revealed that there is a highly significant difference among the student in vitamin D deficiency. In conclusion, low concentration of vitamin D is highly prevalent among the medical students included. An urgent action has to be taken in order to prevent adverse consequences of low vitamin D in young population.

Assessment of the nutritional composition, microbiological and sensory attributes of maize-based fortified food with peanut and carrot blends

This research assessed the nutritional composition, microbiological and sensory attributes of maize-based fortified food with peanut and carrot blends. A total of six composite flour samples were formulated using varying ratios of maize, peanut, and carrot: (MPC1) 100% maize flour (control), (MPC2) 90% maize, 5% peanut, and 5% carrot, (MPC3) 80% maize, 15% peanut, and 5% carrot, (MPC4) 70% maize, 20% peanut, and 10% carrot, (MPC5) 60% maize, 25% peanut, and 15% carrot, and (MPC6) 50% maize, 30% peanut, and 20% carrot. The proximate, mineral, vitamin, antinutrient, and functional properties of these fortified food samples were assessed using established methodologies. The proximate analysis revealed a significant increase (p<0.05) in moisture, crude protein, fat, crude fibre, ash, and energy content of the fortified samples, with values ranging from 1.63% to 3.80%; 3.08% to 44.43%; 2.39% to 15.16%; 3.58% to 7.04%; 2.34% to 3.80%; and 381.75 to 432.52 KJ/100g, respectively, as the supplementation of peanut and carrot flours increased. Conversely, the carbohydrate content decreased from 86.98% to 27.64%. The mineral content of the fortified samples also showed a significant increase (p<0.05) with higher levels of peanut and carrot flour supplementation. The findings of this study indicated a statistically reduction (p<0.05) in the antinutrient profiles of the fortified food samples. Additionally, the vitamin content significantly increased (p<0.05) with the addition of peanut and carrot flours. The overall viable counts were significantly low, and there were no detectable coliform or fungal counts. Although, the result of sensory evaluation indicated that the control sample was more organoleptically acceptable than the substituted samples, incorporating these nutrient-rich and functional ingredients in the production of maize-based cereals may broaden the application of peanut and carrot flours in the creation of various cereal types and other cereal-based food items.

Starr–edwards ball caged mechanical heart valves’ reverberations – need for a phoenix of analysis with a critical mindset

The mechanical heart valve prosthesis with a caged ball has been around for 60 years. It has since experienced changes and adjustments. The Starr–Edwards (SE) valve was a pioneer and was taken out of clinical use in the late 2000s. SE is reportedly close to or has reached the age of 50, according to numerous sources from around the globe. The author’s observations and review of the literature about thrombogenicity, pannus formation, left ventricular outflow tract obstructions, and infective endocarditis in the SE valves, which were reportedly higher before its clinical ending, were only an overestimation and were not supported by scientific data. However, it was less discussed in the article, along with potential benefits. The main reasons for its demise were its obtrusive size and unattractive shape. There have been several successful implantations of these valves in Asian nations and reports of fewer primary failures and unexpected cardiac fatalities. Therefore, there is a need for extensive data gathering, documentation, and more recent studies on these valves to prepare for a prospective revival of use with newer research, mainly when long-term durability is considered.

A secure distributed peer to peer systems

A P2P network can be an ad hoc connection- a couple of computers connected via a Universal Serial Bus to transfer files. And these networks are vulnerable to peers. The traditional security techniques are insufficient for P2P networks as they are insecure by their very nature. There’s no centralized server controlling access to shared resources in a P2P network which have unique challenges including identity management of the peers, secure reputation data management, Sybil attacks, and above all, availability of reputation data. The future actions are predicted where peers are encapsulated in its digital reputation, based on the past behaviour of the peer.Thus a peer’s reputation allows it to cooperate and prevent from malicious activities. The cryptographic protocol is coupled with selfcertification and cryptographic mechanisms for identity management and countering Sybil attack.

In-vitro evaluation of chromium tolerant plant growth promoting bacteria from tannery sludge sample, dindugal, tamil nadu, india.

Industrial waste is one of the most essential sources of contamination in the environment. Chromium (Cr) is a toxic heavy metal, a major contaminant in tannery wastes and its accumulation in soil and water is a major environmental concern today. In the present study, an attempt was made and investigated the status of different beneficial microbes particularly plant growth promoting rhizobacteria (PGPR) from tannery sludge samples collected from tannery effluent treatment plant at Dindugal, Tamil Nadu, India. Experiments were conducted and evaluated their chromium heavy metal tolerance abilities and plant growth promoting activities under in-vitro. Based on molecular analysis, the PGPRs were identified as Achromobacter xylosoxidans (LK391696), Azotobacter vinelandii (LK391702) and. The production of IAA was found to be high by Achromobacter xylosoxidans (46μg/ml) followed by Azospirillum lipoferum (30μg/ml). Phosphate solublization activity was also found to be positive in all these PGPR isolates. Significance of these results revealed that there is a possibility of using these potential PGPRs for bioremediation of chromium contaminated sites and also as good plant growth promoter.

Applying the third-party logistics concept to improve business profitability: a study of the manufacturing industry in the uk

This dissertation aimed to critically investigate how UK manufacturing companies can employ 3PL services to enhance business profitability. A simple, cross-sectional sequential mixed methods research methodology was implemented with the qualitative phase being used to explain the findings of the quantitative phase, which was performed first. Data for the quantitative period were collected using an online questionnaire that was designed and administered through a Google survey (N= 416). At the same time, semi-structured interviews were performed via Zoom calls with senior executives and managers of UK manufacturing firms (N= 5). Descriptive statistics, a one-sample t-test, and stepwise regression were used for quantitative data analysis using SPSS while manual analysis of interview data was performed in Microsoft Excel. The results showed that transportation and fleet management were the services that UK manufacturing companies outsourced to the most significant extent while clearing and forward and inventory management were the services that were outsourced to the lowest degree. The reasons behind this trend included the level of risk involved in outsourcing a particular service, availability of 3PL providers offering the outsourcing service, and the cost involved. In terms of feasibility, all items were scored highly, although increased operational flexibility and significant reduction of operational costs ranked highest. Finally, the stepwise regression test revealed four statistically significant models with an overall prediction power of 20.1% on business profitability. The statistically significant predictor variables were a reduction of operational costs, increased operational flexibility, reduced fixed asset costs, and the gaining of external resources from 3PL service providers.

Intraspecific population variability in goldstripe ponyfish, karalla daura sampled along the pakistan coast based on geomorphometric approach

The use of geo-morphometric variables to discriminate fish populations is one of the appropriate, effective and widely adopted approaches to study population dynamics. To determine intrinsic population variability in goldstripe ponyfish, Karalla daura sampled from Keti Bunder, Karachi Fish Harbour, Hawks Bay and Pasni along the coastal belt of Pakistan. Size frequency distribution based on normal distribution demonstrates that individuals of 13 cm total length were common in all groups. Some fifteen morphometric and six geometric variables were used to develop Principal Component Analysis (PCA) that revealed (76%, 13.9% and 9.8%) variation deduced from first three components. The population sampled from Karachi fish harbors showed significant taxonomic variability. An eigenvalue 7.251 and canonical correlation 0.937 among four groups was appraised from PCI whereas Wilks’ Lambda test of function λ = 0.27 was significant at P <0.05. The highest variance percentage was the most correlated among the groups defined by total length, girth, 2nd dorsal fin, pectoral fin rays, eye dia, snout to extended gill cover and head length parameters. PC-II accounted for 13.9% of the variance that are more correlated with standard length, snout to eye tip, eye tip to first dorsal fin, base of 1st dorsal fin, last fin ray to tip of caudal, anal fin ray to pelvic fin ray, chin to snout and pelvic fin to pectoral fin. PC-III showed 9.8% variance with fork length, total weight, anal fin rays, last anal fin ray to 1st dorsal fin, tip of caudal fin to last anal fin ray, last anal fin ray to 1st anal fin, first pelvic fin to chin, eye to chin, 1st dorsal fin to last anal fin ray and last dorsal ray to last anal fin ray. among the groups. Whereas PC-IV has 0.3 % variance denoted by total weight, tip caudal fin to last anal fin ray. The PCA displayed a clear discrimination by sampling site, especially specimen from Karachi fish harbor were distinct from other location. Keti Bandar specimen was not dispersing as much as by geographical discrimination. Overall, results revealed that different topographies and environmental conditions causing significant variation in populations of Karalla daura. Therefore, it is assumed that this species has ability to adopt different ecosystem for survival despite acquiring adverse impact on phenotypic characteristics.

Effects of hypersaline conditions on the growth and survival of larval red drum-(sciaenops ocellatus)

Texas bays and estuaries experience salinity fluctuations (e.g., droughts, reduced freshwater inflows and hurricanes) caused by natural weather and climate change. This could have impacts on red drum Sciaenops ocellatus (Linnaeus) early life stages beacause red drum spend their early life stage at the shallow bays and estuarine waters of Texas Bay. The purpose of the present study is to evaluate the impact of high salinity concentrations on the survival, growth and development of red drum eggs and larvae. Red drum brood stocks were collected from wild stocks throughout the lower Texas coast and were held in hatchery tanks (13,250 L) until spawning. The water quality conditions were maintained at a salinity of 38ppt and seawater temperature of 25°C. The red drum eggs were hatched at a wide range of salinity treatments (28-48ppt). Egg hatch-out rates and larvae growth were reduced at the lowest (28ppt) and highest (48ppt) salinity treatments. Hypersalinity (≥ 40ppt) and a temperature of 25ºC affected the hatching success of red drum eggs. The percentage of egg hatching success and length of larvae were reduced in both lower (28ppt) and/or hypersalinity (48ppt). This study shows that red drum eggs can hatch within a wide range of salinities with best hatch-out and growth rates occurring between 33 – 43ppt. It also suggests that climate change that produces global warming can keep the increasing environmental salinity of the Texas bay which might have an impact on the development of the early stages of the red drum in their natural environment.

Strategic marketing - blog entry

Marketing refers to the actions that elevate customer value by motivating them to purchase the organisation's products or services (Kusumadewi, 2019). An organisation with strong capabilities must exhibit strong marketing capacities to effectively introduce its offerings to new markets (Lee and Falahat, 2019). Marketing strategies are part of an organisation's corporate strategy, which refers to the set of choices an organisation makes to develop and capture value across its business over time. As corporate strategy essentially drives financial performance (Sull et al., 2018), effective marketing strategies must be selected to ensure the organisation's attainment of objectives and long-term success.

Phytochemical evaluation and pharmacological screening of didymocarpus pedicellata and ashwagandha for antiurolithiatic activity

The kidney stones are one of the most widely spreading disorders in the world. The present study was undertaken to evaluate the efficacy of ethanolic extract of Didymocarpuspedicellata and Ashwagandha for its antiurolithiatic activity in rats. Urolithiasis was induced in adult male albino wistar rats by 0.75% of ethylene glycol for 28 days. The effect of the oral administration of the ethanolicextracts has been studied and is compared with the effect of oral administration of Cystone(Himalaya) as a standard on Wistar rat. Ethylene glycol feeding resulted in hyperoxaluria as well as increased renal excretion of calciumand phosphate. Supplementation with ethanolic extract of the plants significantly reduced the elevated urinary oxalate, showing a regulatory action on endogenous oxalate synthesis. Both the plant extract showed significant antiurolithiatic activity

Large eddy simulation of a utility-scale horizontal axis turbine with woody debris accumulation under live bed conditions

Tidal and riverine flows are viable energy sources for consistent energy production. Installing and operating marine hydrokinetic (MHK) turbines requires assessing any potential impact of debris accumulation on turbine performance and sediment transport. More specifically, MHK devices may alter the natural sediment transport processes and cause debris accumulation, disrupting the natural sediment dynamic. In turn, these processes could affect the turbine’s performance. We carried out a series of large-eddy simulations coupled with bed morphodynamics, introducing various debris loads lodged on the upstream face of a utility-scale turbine tower. The objective is to systematically investigate the impact of debris accumulation on the performance and hydro-and morpho-dynamics interactions of the horizontal-axis MHK turbine under rigid and mobile bed conditions. To that end, we (1) employed the actuator line and surface methods for modeling turbine blades and the nacelle, respectively,(2) directly resolved individual logs, and (3) solved the Exner equation to obtain the instantaneous bed deformation of the mobile bed. Our analysis revealed that while the spinning rotor amplifies scour around the pile, debris accumulation modifies the sediment dynamics of the system. Also, it found that morphodynamic processes accelerate the wake recovery, slightly enhancing the turbine's performance.

Effectiveness of sleep deprivation for electroencephalographic recordings in children with epilepsy with or without cerebral palsy at a nigerian tertiary hospital

Background: Epilepsy and cerebral palsy (CP) are reported as the two most common indications for electroencephalogram (EEG) requests in children in Nigeria. Although several studies have examined epilepsy and EEG findings in the country, most have not documented the conditions under which EEG recordings were performed—whether during wakefulness, natural sleep, sleep deprivation, or drug-induced sleep. This study aimed to compare the effectiveness of sleep deprivation and the use of melatonin in achieving sleep EEG recordings in children with epilepsy and CP versus those with epilepsy without CP, at the Pediatric Neurology Clinic of Usmanu Danfodiyo University Teaching Hospital, Sokoto, Nigeria. Methods: This was a cross-sectional comparative study involving children aged 6 months to 15 years, conducted between March 2022 and February 2023. A total of 121 subjects with epilepsy associated with CP (Group 1) and 124 subjects with epilepsy not associated with CP (Group 2) were consecutively recruited. Conventional inter-ictal sleep EEG recordings were performed using an EEG machine (Model: Satellite P200-132, Toshiba Europe GmbH, DC 19V, 3.4A). Data were analyzed using SPSS version 25.0, and a p-value of <0.05 was considered statistically significant. Results: Of the subjects with epilepsy and CP (Group 1), 67 (55.4%) achieved sleep EEG recordings following sleep deprivation, while 54 (44.6%) required sleep induction with melatonin. Among subjects with epilepsy without CP, 107 (86.3%) attained sleep EEG recordings after sleep deprivation, whereas 17 (13.7%) required melatonin-induced sleep. The difference between the two groups regarding the need for melatonin to induce sleep was statistically significant (p < 0.001). Conclusions: Sleep deprivation was more effective in achieving sleep EEG recordings in children with epilepsy who did not have CP.

Route forecasting-based authentication scheme using a* algorithm in vehicular communication network

Researchers have developed several authentication techniques for route predictions based on user requirements. These techniques estimate the shortest path and available resources in vehicular communication networks. In the current research, the existing authentication techniques for vehicular communication are compared and their inadequacies are identified. Then, new authentication technique based on route forecasting are presented for vehicular communication networks, with the service provider anticipating alternate routes for customers if the current routes have more network traffic congestion. By presenting the most efficient route, the suggested model allows users to maximise their time efficiency. Using A* algorithm, VCN agent seeks path with less network traffic congestion. This algorithm determines the shortest path between a source and a destination. Users are provided with several options by the service provider. User accepts the finest option that meets their needs. This method allows the service provider to deliver at least 15 routes within three seconds. This strategy is beneficial when a significant number of vehicles are stuck in traffic and consumers require network resources to utilise their time effectively.

Weaving teaching and leading: a systematic literature review on pedagogical leadership contributions

Pedagogical leadership has become an emerging and essential debate in the field of educational administration and leadership. This was a result of the shift from the hierarchical type in the past to a more inclusive, collaborative, and participative leadership. Previous studies indicate the furtherance of the inquiry into pedagogical leadership since it is a work in progress. For this reason, a systematic literature review mapped the literature relevant to pedagogical leadership. The review drew the lines between the empirical and theoretical-conceptual contributions, including the methodologies considered in both contributions. The results have implications for a more robust theoretical-empirical model or framework of pedagogical leadership applicable to specific levels of education, especially higher education contexts. The study also implies applying pedagogical leadership in the team, at departmental and organizational levels. Results imply promoting the culture of pedagogical leadership.

Physical activity and physical literacy: the pharmacological benefits of exercise, a women’s perspective

The valuable effects of regular exercise for promotion of health and therapy of diseases were obviously evaluated. The notion that exercise can be considered as a medication has been hypothesized. The growing problems of obesity and non-communicable diseases have placed a great burden on public health experts to promote physical literacy and physical activity among the modern day population. Physical literacy and physical activity have become the cornerstones of women’s health. Women have certain special needs that includes reproductive health. Increased physical activity and maintaining normal body image and body weight will help a woman attain physical, mental and spiritual development. With the growing number of women with obesity and the implication of obesity as one of the main risk factors for non-communicable diseases like diabetes, hypertension, stroke and osteoarthritis, a knowledge and awareness about physical activity is essential. Thus, physical activity is a fundamental aspect of the improvement of motor skills and work performance, allowing a better healthy lifestyle. Physical exercise is effective to be measured as a drug, however, more care should be considered to the dosing and individual variations between genders.

Evaluation of mineralized plasmatic matrix on augmentation of bone resorption

Bone resorption is created by different etiological factors, such as tumors, infections, and trauma. When defects are too large and healing is not possible in a spontaneous way, the defect is called a critical size defect, which is defined as the smallest size of an intra-osseous wound that will not heal spontaneously during the lifetime of the individual. This study was conducted to evaluate the use of a mineralized plasmatic matrix versus bone graft alone or in the augmentation of bony cavities in animals. Ten adult male dogs ranging in age from 12 months to 18 months with a mean weight of ten kilograms were used in this study. Bone cavities were made in the tibia of each animal. The upper holes were implanted with a bovine bone material substitute the medial holes were implanted with a mineralized plasmatic matrix and the lower holes were left free from any implant material acting as control. The dogs were euthanized at 2, 4, and 6 weeks and prepared for H and E stain and trichrome stain. The healing process of bone cavities implanted with mineralized plasmatic matrix was better compared to cavities filled with bone grafts and those left to heal spontaneously. Mineralized plasmatic matrix facilitates graft application, in its stabilization, and improves cell penetration into the graft.
