Background: Exposure to cigarette smoke has been associated with pulmonary and reproductive dysfunctions; inflammatory response, oxidative stress and oxidative DNA damage induced by polycyclic aromatic hydrocarbons (PAHs) present in cigarette smoke have been implicated in the pathogenesis of these disorders. The peak expiratory flow rate (PEFR), a biomarker of inflammation and oxidative DNA damage (8-hydroxy-2-deoxyguanosine (8-OHdG), tumor necrosis factor alpha (TNF-α)), reproductive hormones (testosterone (TST), luteinizing hormone (LH), follicle stimulating hormone (FSH)) cotinine and urinary PAH metabolite (1- hydroxypyrene (1-HOP)) were estimated in male active smokers. Methods: One hundred men aged 20-47 years, comprising 50 active male smokers and 50 non-smokers, were randomly recruited into this comparative cross-sectional study. The PEFR was measured using a peak flow meter, serum levels of cotinine, FSH, LH, TST, TNF-α, and urine 8-OHdG by enzyme-linked immunosorbent assay and 1-HOP by high-performance liquid chromatography. Data analysis was done using a t-test and correlation analysis at p≤0.05. Results: Smokers had significantly higher cotinine (49.73±31.76 versus 0.51±0.69 ng/ml, p≤0.001), 8-OHdG (16.34±12.10 versus 5.79±2.14 ng/ml, p≤0.001) and lower PEFR (309.20±56.05 versus 452.80±45.76 L/min, p≤0.001) and LH (5.75±2.06 versus 6.97±2.79 mIU/ml, p=0.015) compared to non-smokers. Duration of exposure to cigarette smoke correlated positively with cotinine (r=0.937, p≤0.001) and 1-HOP (r=0.813, p≤0.001) while cotinine correlated positively with 1-HOP (r=0.863, p≤0.001) only in smokers. Conclusion: Reduced lung function and luteinizing hormone and concurrent increase in oxidative DNA damage associated with exposure to cigarette smoke may suggest the involvement of PAH-induced DNA damage in the development of pulmonary and reproductive impairment in smokers.

The study was carried out to evaluate the effects of thermal processing treatments on nutrient and antinutrient contents of African yam bean seed flours. The African yam bean seeds were sorted, cleaned and divided into five equal lots of one kilogram each. Four lots were processed into boiled, blanched, roasted and autoclaved African yam bean flours, while the last lot was processed raw and used as control. The flour samples obtained were analysed for proximate, mineral, vitamin and antinutrient contents using standard methods. The proximate composition of the samples revealed that the flours had a range of 6.14-11.24% moisture, 8.18-14.37% crude protein, 3.06-4.61% fat, 2.04–3.32% ash, 3.18–3.56% crude fibre, 62.90–76.98% carbohydrate and 350.57–368.50 kJ/100g energy, respectively. The mineral composition of the samples showed that the flours contained 128.81–174.16 mg/100g calcium, 88.86–212.20 mg/100g, potassium, 134.71–166.77 mg/100g phosphorus, 89.17 – 122.76 mg/100g, magnesium, 14.28–18-11 mg/100g iron and 3.24–5.59 mg/100g zinc, respectively. The vitamin composition of the flours were 1.15–1.37 mg/100g ascorbic acid, 1.15–135 mg/100g thiamine, 1.19–1.55 mg/100g niacin, 1.34–1.85 mg/100g riboflavin, 1.09–1.29 mg/100g folic acid, 1.37–1.95 mg /100g vitamin A and 1.27–1.66 mg/100g vitamin E, respectively. The results showed that the roasted and autoclaved African yam bean flours generally had higher crude protein, fat, ash, crude fibre, mineral and vitamin contents than the boiled and blanched flour samples compared to the raw sample. The antinutrient composition of the flours also showed that the levels of trypsin inhibitor activity, tannin, phytate, oxalate, saponin and haemagglutinin of the samples were significantly (p<0.05) reduced by boiling, autoclaving roasting and blanching treatments compared to the raw sample. However, the study revealed that the processed African yam bean flours have the potentials to be used as nutrient dense ingredients in the preparation of a wide range of food products than the raw sample especially in both underdeveloped and developing countries where the problems of protein-energy malnutrition and micronutrients deficiencies are prevalent.

One of the most important challenges for a company is to manage its supply chain efficiently. One way to do this is to control and minimize its various logistics costs together to achieve an overall optimization of its supply network. One such system that integrates two of the most important logistics activities, namely inventory holding and transportation, is known as the inventory routing problem. Our replenishment network consists of a supplier that uses a single vehicle to distribute a single type of item during each period to a set of customers with independent and deterministic demand. The objectives considered are the management of supplier and customer inventories, the assignment of customers to replenishment periods, the determination of optimal delivery quantities to avoid customer stock-outs, the design and optimization of routes. A genetic algorithm (GA) is developed to solve our IRP. Different crossover structures are proposed and tested in two sets of reference instances. A comparison of the performance of different crossover structures was established. Then, it was used to find the most appropriate crossover structure that provides better results in a minor computation time. The obtained results prove the competitiveness of GAs compared to literature approaches, demonstrate the performance of our approach to best solve large scale instances and provide better solution quality in fast execution time.

In health care delivery systems, if you are not part of the solution, then you must be part of the problem. Over the last few decades, clinical pharmacy encourages pharmacists and pharmacy support staff to move their focus from product-oriented role towards new direct engagement with patients, to make the most of the benefits that patients obtain from the medicine they take, or the problems they encounter with their medicines use. In the USA, pharmacists’ participation in physicians ward rounds was shown to reduce adverse drug events by 78% and 66% in general medical and intensive care settings [1. 2]. A study covering 1 029 US hospitals indicated that centrally based and patient-specific clinical pharmacy services are associated with reduced mortality rates [3]. The services involved were medicine information, clinical research performed by pharmacists, active pharmacist participation in resuscitation teams and pharmacists undertaking admission medication histories. New pharmacists’ roles in healthcare systems around the globe have moved and developed significantly over the past few years, particularly with expansion of the scope of practice which allows pharmacists to focus on the clinical aspects of direct patient care [4, 5]. Pharmacists are drug therapy experts of health care team. Therefore, pharmacists, today, are the arbiters of effective and safe use of medicines. Medication therapy management is one of the major areas in which physicians more and more rely on pharmacists to benefit their patients.

Hyperoxaluria is a metabolic disorder responsible for calcium oxalate nephrolithiasis. The study was conducted on glass slides to observe the growth patterns of urinary calcium oxalate monohydrate crystals and their inhibition by 5, 10, 15 and 20 % infusion of Macrotyloma uniflorum seeds. For this purpose, a drop of gel medium (sodium metasilicate of 1.06 specific gravity and 3M acetic acid solution) at pH 5.02 - 5.17 was placed in the middle of a glass slide and converted into a gel. A 1 M oxalic acid drop was dropped to the left, and 1 M calcium chloride and magnesium acetate (1:1) solution was dropped to the right side of the properly formed gel. The glass slide was observed under a microscope till it was completely dried. In the case of the crystal inhibition study, a drop of M. uniflorum infusion was also added on the right side just after adding calcium chloride and magnesium acetate solution. The results without infusion showed detailed morphology and aggregation patterns of observed crystals such as donut, dumbbell, needles, platy, prismatic, rosette, round edges, X-shape crystals, loose and compact aggregates. All infusions of M. uniflorum affected the crystals, forming defective crystals. 5 % infusion inhibited crystals of all morphologies except donuts, X-shaped crystals, donuts, platy crystals and rosettes. Defected rosettes were observed in 10 % infusion, which was reduced gradually in the crowd by 15 and 20 %, respectively. From this study, it can be concluded that M. uniflorum seeds infusion is effective against calcium oxalate nephrolithiasis.

Medical research is defined as "all scholarly activities that deal with any of the areas of studies being conducted in the pre, para, and clinical areas being taught in a medical school". Such a definition is somewhat arbitrary, as medical research covers a much larger field and ultimately affects every individual. The results of research activities are directly translated into social action, such as pollution control, vaccinations, mass fluoridation and nutritional improvements. The eradication of diseases like smallpox, poliomyelitis and plague, the decline in the death rate from infectious and cardiovascular diseases, and the diagnosis of genetic disorders are some examples of how medical research helps to provide improved health care. Thus, the wealth of medical knowledge that grows through the process of discovery and research development becomes part of daily living. The aim of scientific research is always to extend the frontiers of knowledge and to discover rational correlations and principles [1, 2]. Medical research can be divided into biomedical (basic medical), clinical, and health science research. The areas overlap each other and health science research has a component of social research. Experimental research covers areas such as physiology, biochemistry, microbiology, pharmacology and pathology and is relatively easy to conduct. If adequate financial support is obtained, the necessary infrastructure for laboratory research could be built and experimental animals maintained in an animal house. For clinical research, the patients with a particular disease are the direct object of study. This type of research involves dealing with the clinical picture, diagnosis, therapy and prognosis of the disease. Dealing with human beings requires stringent regulations and precautions to be observed. It requires setting up a research team in the hospital to monitor and chart out guidelines involving the ethical dimension of the problem to be studied and maintain a systematic medical recording system. Moreover, it is through a prolonged study of a large number of cases of the same disease that clinical research learns to predict the likely prognosis and judge the efficacy of the treatment. This type of research activity has limitations in the form of having a restricted number of cases of the disease under investigation, a need to update one's knowledge concerning laboratory techniques from which he obtains his 'cues', and the longer time interval required to complete the work. Health science research is a recent development of medical research due to the demands placed on many health services. More often basic medical and clinical research go hand in hand and are inseparable. Furthermore, clinical research workers often conduct studies on experimental animals, due to either the limited number of human cases or for ethical considerations.

Inlet valve in an engine tends to be subjected to immense thermal loads besides chemical corrosion. Opening and closing of inlet valve practically could be in the order of 2000 times per 1.6 km. In the mean time of engine working cycle, seat insert of the inlet valve is the surface, against which an intake valve seats. Conventional engine valves are provided with a curved angle for its seating position, but for this study, the same is proposed to be positioned at a tapered angle. This tapered position as converted into radius in order to permit rich air at the inlet and reduce exhaust emission. This study is to investigate the nature of the future redesigned Scooping valve for a 1.25L 4-cylinder Petrol engine with VTVT (Variable Timing and Valve Train) under combined mechanical and thermal loading cycle by feeding the input conditions for this study after NX-CAD modelling in ANSYS 10.0 software and the numerical results thus obtained are recorded for future valve design considerations.

Education is power. It constitutes the foundation of all the multidimensional socio-economic development of a country. In the present context, we need manpower or human capital for generating the growth and development in a country. The Government of India has taken several many initiatives for promoting education at all the stages i.e. Primary, Secondary and Higher. But still, we find such issues as a high dropout rate at all the stages of education, rural-urban disparity, gender disparity, interstate variations pose as some of the problems that impedes the development of human resources in our country. Even the work participation rate in India indicates the necessity of proper planning of skill training and employment opportunity. Most interestingly, the existing general and conventional higher educational institutions have not effectively been able to cope with the contemporary challenges and changes with the result that the nature of curriculum which is by and large in place tends to create only degree inflation in our country. So, we need such institutes and institutional arrangement that can cater to the contemporary challenges so as to upgrade the quality of education as well as to provide need based educational programmes that can develop human power in the society. Effective or quality education especially at higher level can play a vital role in bringing around multifaceted human resource development, enabling the learner’s absorption in the job market and selfemployment. This paper will discuss how the accessibility of education can be promoted to all through a convenient mode of education system and how the disparities in education can be minimized, and also focus on the various strategies for strengthening higher education system in the country.

This study's objective was to determine the distribution of allele frequencies of CYP2C9 and CYP2C19 gene polymorphisms among the Papuan population, known as the second-largest ethnic group in Indonesia. According to recent research, there is a decrease in CYP2C9 and CYP2C19 produced by humans globally, including in Indonesia. These gene polymorphisms aid in the transmission of various endogenous and exogenous drugs in the human body. Material and Methods: A sum of 99 subjects, comprising 73 male and 26 female subjects aged 20-30 years, were used for this research. PCR-RFLP (polymerase chain reaction-restriction fragment length polymorphism) analysis using AvaII, NsiI, and SfaNI enzymes tested for the genotypes CYP2C9 and CYP2C19 administered. The distribution of genotypes was calculated in the population (P<0.05) using the Hardy-Weinberg equilibrium. The Faculty of Medicine Gadjah Mada University's Medical and Health Research Ethics Committee (MHREC) accepted this research with written consent. The results revealed that in Papua subjects, CYP2C9*2 (rs1799853) and CYP2C19*17 (rs12248560) alleles were absent while in 17 percent of the population CYP2C9*3 (rs1057910) allele frequency was. In conclusion, CYP2C9*3 has the highest polymorphism rate in Indonesia, with the absence of CYP2C9*2 and CYP2C19*17. Therefore, genetic drift can occur within this ethnic group.

The skin provides an effective barrier and only limited number of drugs can penetrate in adequate amounts. This study aims to identify the relationship between the physicochemical properties and permeation across mouse skin of non-steroidal anti-inflammatory drugs in view of their feasibility to transdermal delivery. Biphenylacetic acid, diclofenac base, diclofenac sodium, indomethacin and piroxicam are the drugs studied. Number of physicochemical properties studies were performed. Drug permeation studies across hairless mouse skin were carried out using an in-vitro finite dosing diffusion cell. The relationship between physicochemical properties of the drugs studied and their percutaneous penetration was studied. Purity for the compounds studied ranged from 99.09% to 100% in which 99.89% purity was obtained for diclofenac base. At 7.4, the % ionized of piroxicam was found to be 95.12%, while for other drugs were in the range of 98.01% and 99.96%. The true partition coefficient values in the n-octanol/water system are in the range of 1.85 and 2.85, while in the n-octanol/phosphate system ranged from 2.14 to 3.70. Observed solubility in water, phosphate buffer and n-octanol ranged from 0.033 to 0.322, 0.202 to 0.329 mg per ml, and 2.19 to 16.10 mg per ml, respectively. A linear relationship was found between water solubility and melting point between steady-state rates of permeation across intact and viable skin, between n-octanol solubility and maximum predicted flux and between molecular volume and the ratio of maximum predicted flux. Predicted flux calculated was compared with the experimental data which resulted in a high correlation. Physicochemical criteria which were determined the feasibility of non-steroidal anti-inflammatory drugs studied for transdermal delivery were identified. The relationships obtained in this study provide an essential physical and chemical properties that govern transport of non-steroidal anti-inflammatory drugs across hairless mouse skin.

The adulteration and substitution of crude drugs is a burning problem. No doubt, substitution is helpful in places where the unavailability of particular oil drugs and or unwanted adverse effects of the desired crude drugs are there and have a choice of another drug with similar pharmacological effects and less unwanted aftereffects. However, in most cases, it is unacceptable because the conversion of authentic drugs into substandard medications may cause a variety of adverse effects, from mild and moderate to severe life-threatening reactions. So, understanding all the ways of adulteration and substitution is necessary to rectify this illegal act and maximize consumers' safety. At the end of this review, the Botanical Adulterant Program of the American Botanical Council is also highlighted.

The free senior high school policy is one of the best social and economic intervention policies that openly affect both parents and their wards in senior high school. This realisation is reached on the backdrop of the policy’s role in redeeming parents from their economic and financial burden. This study, therefore, looks at the effect of introducing the free senior high school policy on the economic and social lives of parents and students respectively. A correlational cross-sectional descriptive design was used. Questionnaires were administered to three hundred and thirty-six (336) parents of wards in three senior high schools in the North East and Upper East Regions of Ghana. The study confirms that the introduction of the free senior high school policy relieved the financial burden of parents, especially guardians from rural settlements. Besides, there was a lack of adequate stakeholder consultation, hence saddled with implementation challenges. Delay in disbursement of funds for feeding and learning materials presented yet another problem. It is important that governments find sustainable sources of funding for the educational system and also ensure the double-track system is regularised into a single-track system by expanding academic user facilities and increasing the numerical strength of both teaching and non-teaching staff in various senior high schools.

Background: Preanalytical variability due to anticoagulant choice remains inadequately characterized in resource-limited tropical settings like Yemen, where environmental stressors exacerbate challenges. This study aimed to compare the stability and cost-effectiveness of K₂EDTA and K₃EDTA anticoagulants for complete blood count testing under simulated Yemeni conditions. Methods: Prospective study of 100 healthy adult male volunteers in Ad’Dla Governorate, Yemen (January–March 2025). Paired samples in K₂EDTA/K₃EDTA tubes were analyzed at baseline (T0) and after 6-hour storage at 22 ± 2°C (T6). Statistical analysis included Bonferroni-corrected repeated-measures ANOVA and paired t-tests. Results: Fresh samples showed high inter-anticoagulant concordance (ICC > 0.90). After 6-hour storage, K₂EDTA exhibited significant Mean Corpuscular Volume (MCV) reduction (Δ = −2.33 fL, p < 0 xss=removed xss=removed xss=removed> 2 hours), while K₃EDTA is preferable for immediate analysis. These findings provide preliminary guidance for hematology testing in Yemeni laboratories and similar tropical settings, pending validation in diverse populations and extreme conditions.
