Wheat bran and groundnut shell powder have been used to study the mechanism of diclofenac sodium adsorption from aqueous solution using batch as well as column modes and maximum uptake is 84.3% for wheat bran and 82.4% for groundnut shell powder at pH 6, drug concentration 1mg/L at 298 K for 30min. Isotherm and error analysis reveals that Freundlich and Langmuir isotherms fitted well. Kinetic studies show that the adsorption process follows second-order kinetics and thermodynamic study shows endothermic adsorption process. Column adsorption study is important for industrial scale adsorption and column studies have been carried out using vertical bed and sequential bed adsorption columns at pH 6 which is the optimum pH for maximum adsorption for batch experiments. Vertical and sequential bed columns setup is simple and economical which provides flow under gravity. The effect of varying inlet feed concentration and flow rate on the breakthrough and exhaustion time of columns has been studied to determine the bed capacities of both columns. Thomas model and Yoon-Nelson models fitted well with experimental data for continuous flow column studies.

Preterm birth, defined as delivery before 37 weeks of gestation, remains a leading cause of neonatal morbidity and mortality globally. One of the developmental challenges in preterm infants is the immaturity of the sucking-swallowing-breathing triad, which hinders successful oral feeding. Non-Nutritive Sucking (NNS) is an innate reflex in neonates that involves sucking motions without the intake of nutrition. This behaviour, often facilitated by pacifiers or a gloved finger, plays a vital role in neurodevelopment, feeding maturity, and physiological regulation in preterm infants. Recent studies also highlight its psychological and lactational benefits for mothers. This review presents a synthesis of current evidence supporting NNS as a low-cost, non-invasive intervention with multidimensional benefits for both preterm infants and their mothers.

Objective: To study the use of cefazoxime sodium for injection in inpatients of the Third People’s Hospital of Yancheng City, and to provide reference for the rational clinical use of cefazoxime sodium. Methods: A retrospective study method was used to retrieve the medical records of patients discharged from 2 departments of urology and general surgery of the hospital using cefazoxime sodium in June-August 2023, and the rationality of the clinical use of injectable cefazoxime sodium was evaluated with reference to the relevant standards. Results: A total of 328 valid cases were included, of which 6 cases did not meet the dosage criteria, 10 cases did not meet the treatment time criteria; 44 cases did not meet the indication criteria. The comprehensive judgement of the reasonableness of the clinical use of cefazoxime sodium for injection resulted in 272 cases of reasonable use of the drug; 56 cases of unreasonable use of the drug. Conclusion: The clinical use of cefazoxime sodium for injection in this hospital is irrational and needs to be further strengthened and corrected.

This study used smartphones as an Instructional tool to determine their effects on students’ Interest and retention in Agricultural Water Engineering in Colleges of Education, Benue State, Nigeria. Five purposes of the study were stated, five research questions were posed and answered with means and standard deviations, and five hypotheses formulated and tested at 0.05 level of significance using Analysis of Covariance (ANCOVA). Quasi-experimental design of non-randomized pre-test post-test control group design was utilized. The research was carried out in two Colleges of Education in Benue State, Nigeria, with a population of 410 NCE Students. The population size of 200 NCE III students was sampled from colleges of Education, Katsina-Ala and Oju in the study area. The research instruments were ‘Basic Agricultural Water Inventory Test’ (BAWEIIT) and Basic Agricultural Water Retention Test (BAWERT), AND were validated by three experts. The reliability coefficient of the instruments was 0.74. The study found that the students who were taught with SIT demonstrated positive interest and enhanced their retention (XS=3.92) in Basic Agricultural Water Engineering than those taught without Smartphones. Also, there was no significant difference in the mean interest and retention rating scores (XS = 1.24 > 0.05), in Basic Agricultural Water Engineering (AGE, 324) concepts with Smartphone as an instructional tool (SIT). Based on findings, recommendations were made that smartphone (SIT) should be included among instructional materials in the scheme of lesson delivery for lecture by the National Commission for Colleges of Education (NCCE) in the curriculum for both teaching and learning activities at the Colleges of Education in Benue State. There should be constant, strong Wi-Fi connections power National Commission for Colleges of Education instructional via College administrators should orient lecturers and students by organizing workshops and seminars on how to effectively utilize smartphones for their academic activities. College administrators should endeavour to supervise implementation of smartphones as instructional tools in Agricultural Water Engineering and NCE courses for students

The external force in the relativistic equation of motion can be separated into two components: Fr and Fp. The first is expressed by the physical force divided by the square of the relativistic Lorentz factor, i.e γ2. This force dominates for non-relativistic velocities and vanishes for velocities approaching the speed of light c. On the other hand, the second term increases from zero with increasing velocity and dominates for velocities close to c. It is then a purely relativistic component. The characteristic feature of this component is its zero power, Fp ⋅ v = 0, but it is responsible for the relativistic precession. The effect was confirmed by numerical solutions of the equation of motion. Relativistic formulas for the precession frequency for point objects moving in selected fields of central forces were also derived analytically. It has been shown that for weak gravitational interactions, the correction for relativistic precession is small, negligibly small for Earth, and relatively small, though measurable, for Mercury. In turn, for the microworld and electrostatic forces (e.g., for the hydrogen atom), relativistic precession can fundamentally affect the movement of the electron.

Lichen Planopilaris is known as the form of Lichen Planus typical of the scalp. It is classified as a lymphatic disease and is characterized by chronic inflammation which leads to cicatricial alopecia. Its causes are not yet well characterized but its etiology seems to strongly correlates with infection, sensitization and pollution. A clear and objective diagnosis of Lichen Planopilaris is not simple but the evolution and strongly negative outcomes on scalp of people affected by, pose the need of an early diagnosis. In this work we report the case of a 27-year-old male and a 54-year-old female, respectively, in which a correct diagnosis of Lichen Planopilaris, followed the incorrect previous ones, was made by means of dermatoscopy and histopathological analysis, decisive tools for the diagnosis of this kind of pathology.

Gynecological laparoscopy has to be analyzed also in the context of complications that occur during the surgical procedures. Complications occur daily. For this reason, emphasis should be placed on lifelong continuous education and training. Given the risks and complications we face, we must be trained to deal with them. This improves the safety of laparoscopic operations. Without such certainty, gynecological laparoscopy would not be the method of choice in a minimally invasive approach. This requires significant commitment, effort, and responsibility. In this way, we provide our patients with the best and highest quality healthcare service. Likewise, with such an approach, the frequency of complications is reduced to a minimum. New perspectives and possibilities are associated with the application of robotic surgery.

Veterinary and agricultural surfactants are supposed to be inert additives, yet these substances commonly exert biological side-effects, in given cases synergistic with those of the active ingredients of these preparations. This is explicitly seen in altered toxicity of veterinary or pesticide formulations compared to their active ingredients alone. Neither the individual effects of these excipients, nor such combination effects are well-studied in toxicology, and therefore, possible toxicity consequences are occasionally not being considered at sufficient significance in the authorization, use and control of these substances. Risk assessment of these substances should cover all hazards they may represent, and corresponding levels of exposure. Surfactants used in veterinary and pesticide formulation enter the environment either by direct dispersion or by indirect release through excrement, leaching, sewage waters or sludge, and in turn, create potential exposure to a number of non-target organisms. Biochemical and (eco)toxicological hazards recently identified regarding certain agricultural surfactants include cytotoxicity (on cell lines of epithelial, neural and other tissues, as well as stem cells and tumor cells), endocrine disrupting effects, as well as aquatic ecotoxicity. This Mini Review summarizes toxicological effects identified in our studies in aquatic toxicity tests, in cell viability and cytotoxicity tests, in estrogenic activity assays, correlated with biochemical analysis of the surfactants and their decomposition. The conclusions are hoped to facilitate environmentally precautious revision of surfactants widely used in agriculture.
