Chemopreventive effect of celecoxib and expression of cyclooxygenase-2, Casapase-3 and AGNOR on chemically- induced rat submandibular salivary gland neoplasm

BACKGROUND: Cyclooxygenase-2 (COX)-2 inhibitor (Celecoxib) is a non-steroidal antiinflammatory drug (NSAIDs) and over-expression of COX-2 protein and mRNA has been reported in various cancer tissues. Therefore, it has been suggested that COX-2 is related to carcinogenesis. METHODS: Twenty five albino rats were used . They were divided into 3 groups; group I (normal control) and group II and III which was delivered 4-NQ in the drinking water . Meanwhile group III was given 1500 ppm celecoxib. Submandibular salivary glands were obtained after 32 weeks. Immuno-histochemical staining for COX-2 was performed to determine the COX-2 level and Caspase-3 immuno-expression was done for detection of apoptosis and silver nitrate staining of nucleolar organizer regions (AgNORs) was done for estimating the proliferating cells. The data were analyzed using Student's independent t-test and one-way analysis of variance (ANOVA). RESULTS: The group II and III showed pathological evidence of cancer. COX-2 immuno-staining was stronger in group II than in Group III. Caspase-3 immuno-reaction was statistically highly significant in group III (p<0.05) . Meanwhile proliferation estimated by AgNOR nuclear count was statistically highly significant group II (p<0.05). CONCLUSION: The COX-2 expression was increased in group II (untreated group) than group III. Administration of celecoxib demonstrated the chemo-preventive potential against the carcinogenesis through induction of apoptosis and suppression of tumor growth and proliferation. [Mohamed Zayed.

Theoretical and practical implications are also provided.
Dermatophytosis among Basic School Children in Menoufia Governorate (Epidemiological Study)

Back ground: Most superficial mycotic infections of human skin are due to dermatophytes. Children are mostly affected due to different predisposing factors especially overcrowding in classrooms. Meanwhile its transmissibility can be controlled through simple school-health measures. Objectives: This study was performed to estimate the prevalence of dermatophytes infections and their related risk factors among the primary and preparatory school pupils. Methods: In Menoufia governorate, Egypt, by using multistage random sampling technique, six public primary and preparatory schools were selected with a total number of 3464 pupils. The selected pupils were subjected to a predesigned questionnaire covering personal data and suspected risk factors for superficial dermatophyte infection, clinical examination to detect superficial dermatophyte infection with taking samples from the suspected lesions for mycological examination. Results: Among the studied pupils with age ranged from 6 – 14 years, the prevalence of clinically suspected dermatophytes infection was (1.41%) meanwhile the prevalence of culture confirmed cases was (0.98%). The most common clinical type was tinea capitis with specific prevalence (1.01%) followed by tinea pedis, tinea corporis and Onichomycosis. Microsporum canis was the only isolated organism on culturing the suspicious samples with positivity rate (69.4%). A statistically significant higher prevalence was observed among males, those with low socio economic level and with the presence of positive family history. Dealing with pits, common use of towels and sharing caps among pupils were significant risk factors of these infections. Conclusion: Dermatophytes infection is still prevalent among basic school children in Egypt. It was simply controlled as it was related mostly to preventable risk factors, so, health education program and regular screening should be advised for schools authorities.

Finite Element Analysis of Reinforced Concrete Continuous Beams Strengthened by External Layers

Repair and strengthening of the existing constructions are very essential in many cases and may be the sole right decision. A computer program based on the finite element method has been developed and a new compound element was used to simulate the reinforced concrete members strengthened with external layers on the different sides. Each compound element consists of four sub-elements. The sub-elements are two dimensional isoparametric degenerated elements with eight nodes and five degrees of freedom. Each sub element consists of different concrete, steel and strengthening laminates. Seven models from an experimental test program of RC beams strengthened with external layers in different sides were analyzed by the finite elements. The new developed compound element has been proved to be capable to solve any reinforced concrete member strengthened with additional external layers at different sides with accurate representations and acceptable results.

EFFECT OF FRACTION 1 OF PORTULACA OLERACEA ON REPRODUCTIVE PARAMETERS IN MALE WISTAR RATS

Portulaca oleracea is a fleshy annual herb which is distributed throughout the temperate and tropical areas of the world. The crude extracts of this plant have been reported to have deleterious effects on reproductive parameters in male rats. Air-dried specimen of Portulaca oleracea was cold-extracted in methanol for 72 hours. The resulting methanol extract was then subjected to open column chromatography on silica gel for fractionation. Out of the 5 fractions obtained, fraction 1 was then subjected to male rats’ reproductive bioassay. Twenty male rats (120 150 g) were divided into control (distilled water) and fraction 1 (1, 2, 3 mg/kg) treated groups (5 per group) for hormonal assay and andrological study. The animals were orally treated on daily basis for 50 days. Plasma testosterone level was assayed using Enzyme-Linked Immunosorbent Assay (ELISA) and semen analysis was done microscopically. Treatment of rats for 50 days with fraction 1 (1 mg/kg, 2 mg/kg, 3 mg/kg) caused significant (p<0.05) increase in testosterone level relative to the control. Fraction 1 (3 mg/kg) caused significant (p<0.05) decrease in sperm motility and sperm count of rats relative to their respective controls. It can therefore be concluded that chromatographic fraction 1 of Portulaca oleracea probably has deleterious effect on the reproductive parameters in male rats.

Knowledge, attitude and practices towards consumption of caffeine containing drinks among the student population of Ras al-Khaimah medical and health sciences university, UAE

Background: Caffeine, world’s most widely consumed and legally accepted psychoactive substance which is commonly found ingredient in many drinks like coffee, tea, carbonated drinks and energy drinks. The objective was to explore how much dependent are the teenagers and young adults on caffeine containing drinks, reasons and circumstances for the consumption and to know the knowledge and attitude of the consumers about the health effects of the caffeine containing drinks. Methods: A validated questionnaire was administered randomly to about 298 students from MBBS, BDS, B Pharma and Nursing programmes of RAK Medical and Health Sciences University (RAKMHSU). Results: Out of 298 students in the study, 97% (n=290) of them drink caffeinated beverages in the form of coffee (53%), tea (43%), energy drinks (17%), carbonated drinks (18%) and all of the above (11%). The major reasons for consuming varied, where more than half of them gave the reason as to keep them awake for study purpose (53%), to get refreshed (51%), taste and flavour (49%). About 56% were of an opinion that they do experience different symptoms if they don’t consume their daily caffeine intake. 54% students admitted their caffeine consumption has been increased after joining the university. When knowledge and attitude were questioned, 63% of them think caffeine addiction is a health issue and majority of them were aware of the ingredients of these drinks but not the safest amount. Conclusions: Drinking caffeine containing drinks by the students are variable from different sources, so monitoring is necessary for the daily intake and there is need for educational programmes about the health effects related to high consumption of caffeine.
Looking at the Schrödinger Equation For Nanotechnology

Quantum mechanics brings together a set of physical theories of the first half of twentieth century that describe the behavior of matter at microscopic level, at length scales of order or less than the atomic ones, where the assumptions of the classical mechanics fall. Through the quantum reality it is possible to analyze and properly explain phenomena, which cannot be justified by classical mechanics, providing this last in such cases predictions in disagreement with the experimental results. A quantum level the state and the evolution of a physical system are described in an intrinsecally probabilistic way, utilizing a “visualization” of the particle behaviour in terms of “wave function” or “probability wave”. Such probability wave is associated to quantities, such as the spin, that do not have an equivalent at classic level, as instead are the position and the moment characterizing the common wave function [1]. The spin assumed a significant position in the world of nanotechnology in relation to spintronics, spin-based electronics. Spintronics studies the electronic and spin structures of materials. Conceived as storage technology and information processing, it is a bridge between electronics and magnetism, entrusting to the carriers spin, rather than to the modulation of the electric charge, the binary encoding. The electron spin, being quantized and having two possible configurations, lends itself naturally to the implementation of the binary code. The spintronic devices are designed in such a way that an interaction between an external magnetic field to the structure and the carriers flowing inside is produced, because the spin is associated with a magnetic moment that is affected by external magnetic fields, making possible the modification of the device status. Since the carriers are electrons, the spin is present in both the traditional and the spintronic devices [2]. In the domain of nanotechnology, the classical physics is partially usable, but the quantum aspect cannot be neglected. In particular, the use of the Schrödinger equation is very convenient and complete [3]. Therefore it is useful to consider qualitative and quantitative information’s about the Schrödinger equation applied to quantum dots and wires, of interesting interest in the nano-bio-devices and nano-bio-sensoristics sectors.
Efficacy of Bioagents and Fungicides against Sclerotium rolfsii of Tuberose

Tuberose (Polianthes tuberose L.) is one of the important ornamental crops being cultivated mainly for its cut and loose flower and oil trade in the tropical and subtropical regions of India. Tuberose is reported to be affected by many diseases of which stem rot caused by Sclerotium rolfsii is the most important one in the tuberose growing regions of Tamil Nadu. The commercial cultivation of tuberose has been hampered due to the occurrence of root rot (Das, 1961). Little work has been done on the management of diseases of tuberose. Hence, it is necessary to evaluate bioagents and fungicides in vitro condition to formulate management strategy against root rot of tuberose.

The growth factor effect on endothelial cell dysfunction in the presence of glycated collagen and Abeta peptide: implications for decreased angiogenesis in diabetes and Alzheimer's disease

The growth factor effect on endothelial cell dysfunction in the presence of glycated collagen and Aβ peptide: implications for decreased angiogenesis in diabetes and Alzheimer’s disease. Reduced angiogenesis, the growth of new blood vessels from existing vessels, is important in disease states including diabetes and Alzheimer’s disease. People with diabetes experience morbidity and mortality from unregulated micro-vascular remodeling, which may be linked to hyperglycemia. People with Alzheimer’s disease experience diminished memory and motor function from a buildup of Aβ plaques and a reduction in microvascular density. The primary focus of this research is to determine if growth factors can rescue endothelial cell angiogenic processes from altered extracellular proteins, specifically glycated collagen and Aβ peptide. Assays were developed to discover how these altered extracellular proteins affect growth factor induced cell plasminogen system activity. The resultant data would then add additional insight into growth factor therapy for patients with diabetes and Alzheimer’s disease. Endothelial cells on glycated collagen displayed decreased plasminogen system activity, which impacted angiogenic functions such as tube formation and 3D migration. FGF-2 did not fully rescue the negative effects of glycated collagen. uPA, uPAR and PAI-1 protein levels did not significantly change at short time points. However, PAI-1 bound to glycated collagen at higher levels than native collagen. Since even cells on native collagen did not show a short term response in uPA, PAI-1, or uPAR protein levels in response to FGF-2 stimulation, FGF-2 effects on vitronectin were explored. FGF-2 increased cell-associated vitronectin by 24 hours in varied endothelial cell types and vascular smooth muscle cells.
Heterosis and Combining Ability in Aromatic Hybrid Rice (Oryza sativa L.)

Out of seventy two hybrids developed by 4 x 18 Line x Tester crossing programme in aromatic rice, carried out at Navsari Agriculture University, Navsari, 14.74 per cent standard heterosis was observed for grain yield plant over aromatic hybrid check Pusa RH 10 in KJTCMS 6A x Pusa sugandh 4, followed by IR 58025A x Pusa sugandh 5 (13.79%) and IR 58025A x SKL 41-30 (10.79%). The range of standard heterosis over GR 104 was -34.37 per cent (RTN 17A/GR-104) to 35.02 per cent (IR 58025A/Pusa sugandh 5) and -44.23 per cent (RTN 17A/GR-104) to 14.74 per cent (IR 58025A/Pusa sugandh 5) over aromatic hybrid check Pusa RH 10. Among the hybrids with positive and significant SCA effects for grain yield, the frequency of good x good combiner was more. Regarding combination of parents among top three hybrids, it was found that, topmost hybrid KJTCMS 6A/Pusa sugandh 4 had combination of average x good parents and hybrids IR 58025A x Pusa sugandh 5 and IR 58025A x SKL 41-30 were having both the parents of good performance. Among top eight performing hybrids, three hybrids viz. KJTCMS 6A x Pusa sugandh 4 followed by IR 58025A x Pusa sugandh 5 and IR 58025A x SKL 41-30 exhibited significant favorable heterobeltotis, standard heterosis, GCA and SCA effects for yield and most of the related traits. Hence, these could be utilized for commercial cultivation after proper evaluation by means of multi-location trials.
