Abstract: Background & aim: The aim of this study was to review and evaluate the quality of communication, instructions and prosthodontic prescription given to profitable and governmental dental laboratories by general dentists, restorative dentists and prosthodontists for shortened dental arch cases treated in Jeddah, Saudi Arabia. Methods: Over the period of six months, a cross-sectional survey with self-designed-structured questionnaires was conducted. A survey of the main five governmental and private dental laboratories was carried out. 200 questionnaires were filled by an interview and case discussion with each dental lab technician who received a case for shortened dental arch (SDA). Results: A sample size of 200 male dental technicians were interviewed. 91% of them were not Saudi. In addition, 25.5% had an experience for more than 25 year.67.5% of the dental technicians were working in private laboratories. Most of the cases received (76%) were for lower arch. The most treatment option that were selected by dentists were the Co-Cr RPD 86.5%. The majority of the cobalt chromium RPD cases (64.2%) had instruction form without mentioning the clasp material. The most common major connector selected for the lower arch cases 55.5% was lingual bar and a U-shaped major connector in the upper. Conclusions: It would appear from the results of this survey that amid the different restorative treatment choices for SDA, Co-Cr RPDs are the most common. The prescribing dentist’s signature, clasps’ material and date the prosthetic work required were the most frequently absent sections of information. Recommendations for improved communication, clear, complete and signed prosthodontics laboratory form of better patient service.

Background: Identification of E.coli is an important task in both public health and clinical microbiology laboratories. Escherichia coli is responsible for a wide variety of diseases in human and animals, including urinary tract infections, diarrhea, septicemia, hemorrhagic enteritis, respiratory diseases and ear infections. Pathogenic isolates of E.coli are of special significance . Therefore, a rapid, inexpensive method to presumptively identify E.coli isolates with a high degree of specificity and sensitivity is desirable. We developed a single-tube method as a screening test for E.coli from various clinical specimens and also could be used for environmental samples . Aim: To evaluate a novel medium in a single tube, for screening isolates suspected to possibly represent E.coli and comparison of its results to results of the classical IMViC plus H2S, Urease and Arabinose 7 tubes (FDA) procedure. Materials and Methods: To evaluate the method, (398) strains of Gram-negative isolates were tested. We tested this tube with, (213)E.coli isolates, and (185) Non E.coli Gram-negative isolates all were selected based on conventional biochemical reactions and FDA procedure. ATCC quality control organisms were evaluated as well to ensure accuracy. Results: All (100%) of E.coli isolates tested were appropriately characterized by using this single tube with this medium. Similarly, (100%) of other Gram-negative bacilli were appropriately screened as non-E.coli. This tube correctly identified 100% of E.coli isolates compared to FDA procedure. Conclusion: This unique medium provides the most important biochemical reactions needed to screen for E.coli and other Enterobacteriaceae in a single-tube format, which decreases labor by 85%  (i.e, 1 tube is inoculated vs 7 ).

Abstract: A rutin-ca complex was synthesised in methanol and was characterized using elemental analysis, UV-Vis spectroscopy, IR spectroscopy and differential thermal analysis. Spectroscopic data suggested that the metal/ligand ratio of the complex is 2:1. The antihyperlipidemic activity of the complex was evaluated by animal experiment of 30 wistar rats. It was shown that the complex was much more effective antihyperlipidemics than the free flavonoid.

Abstract: Sedation and analgesia are important therapies for mechanically ventilated patients who suffer from enormous stress. To avoid oversedation, daily sedation interruption (DSI) is pervasively advocated. However, it is usually assessed by doctors, and it was an increasing concern that DSI could be performed by nurses alone. To evaluate the effects of DSI on patients with mechanical ventilation in ICU, we conducted a prospective and randomized trial. One hundred and twenty patients with mechanical ventilation from January 2013 to December 2013 were recruited and randomly divided into two groups, observational group, in which DSI was decided and carried out all by nurses independently (n=60), and control group (n=60). Data about dose of sedation, complete arousal time after sedation, duration of mechanical ventilation, sedation time, and the length of ICU stay, as well as occurrence of adverse events, were all recorded and compared. Our study demonstrated that observational group had lower sedation dose, shorter fully wakening time after drugs withdraw, shorter time of mechanical ventilation, total sedation time, and hospital stay in ICU. In conclusion, DSI conducted by nurses was an effective method which should be adopted in patients with mechanical ventilation in ICU.

Abstract: Factors affecting pain sensation are not fully known. This study examined the effects of gender, age, body mass index, somatosensory amplification, anxiety, and depression on the perception of pain. Venipuncture was performed on 140 healthy individuals. All cases completed a sociodemographic data form, visual analogue scale (VAS), Beck Anxiety Inventory (BAI), Beck Depression Inventory (BDI), and Somatosensory Amplification Scale (SAS). Height and weight were measured. When the genders were compared, there was no difference in terms of VAS, body mass index (BMI), age, and BDI in women compared with men, but SAS and BAI were found to be higher in women. A correlation was found among VAS points, BAI, and BMI. The results of regression analysis show that the BAI score is a predictor for the VAS score. These results indicate that anxiety may be a predictor of pain, whereas gender, depression, somatosensory amplification, age, and weight do not appear to influence the perception of pain.

Abstract: Typha latifolia is traditionally used for the treatment of cancer, heart problems and skin diseases in Pakistan. The present project was therefore arranged to study the protective effects of methanol extracts of Typha latifolia (TLME) ethno pharmacologically against lead nitrate induced hepatic common carp. To study the protective effects of TLME, 40 Cyperinus carpio were equally divided into 4 groups (10 rats). Group 1 was given normal diet (control). Group II was treated with lead nitrate (100 ppm) alone while Group III and IV were given 250 ppm and 500 ppm of TLME (for a week) along with lead nitrate (100 ppm). After a round of the clock of the last treatment fish samples were weighed, anesthetized with tricaine methane sulphonate (0.2 g/L of distilled water) and the peripheral blood on mid-ventral line was collected. After that fish were euthanized by anesthetizing overdose. Operculum and peritoneal cavity were dissected and liver were collected. Liver was placed in -20 C freezers for further enzymatic analysis. Administration of lead nitrate altered the level antioxidant enzymes viz; Catalase (CAT), peroxidase (POD), reduced glutathione assay (GSH), lipid per oxidation (TBARS), super oxide dismutase (SOD), glutathione-S-transferase (GST), glutathione reductase (GR) and glutathione peroxidase (GPX). Supplement of TLME ameliorated the effects of lead nitrate improved antioxidant enzymes and lipid per oxidation contents (TBARS. The results revealed that TLME effectively protect liver against the lead nitrate induced oxidative damage in rats, through antioxidant and free radical scavenging effects.

Abstract: The development of multiple antibiotic resistances in microbial communities is gaining momentum as many chemotherapeutic agents are obsolete and ineffective to curtail the menace of pathogenic microbes. Consequently, efforts are now geared towards the development of new potent antibiotics while we explore the potentials of drug combinations to improve antibiotic effectiveness. This study investigated the effect of combining benzylpenicillin, streptomycin and amoxicillin against bacterial isolates by agar dilution and agar diffusion methods. The results showed that streptomycin was the most effective against the bacterial isolates having MICs ranging between 2 g/ml and 200 g/ml while amoxicillin inhibited the bacterial isolates at MICs ranging between 20 g/ml and 400 g/ml and benzylpenicillin inhibited the isolates at concentrations ranging between 20 g/ml and 200 g/ml. Amoxicillin combined with benzylpenicillin and amoxicillin combined with streptomycin were not synergistic against any isolate. Amoxicillin combined with benzylpenicillin resulted in additive interaction against K. pneumoniae ATCC 1538, S. aureus ATCC 29213 and E. coli ATCC 23922 but antagonistic against E. coli ATCC 25922 and P. aeruginosa ATCC 27853. Amoxicillin combined with streptomycin resulted in additive interaction against E. coli ATCC 23922, K. pneumoniae ATCC 1538 and E. coli ATCC 25922 but antagonistic against S. aureus ATCC 29213 and P. aeruginosa ATCC 27853. Benzylpenicillin combined with streptomycin resulted in synergistic interaction against S. aureus ATCC 29213, E. coli ATCC 23922 and P. aeruginosa ATCC 27853, additive interaction against S. aureus ATCC 29213 and antagonistic interaction against E. coli ATCC 25922. This study showed that synergistic drug pairs can effectively eradicate bacteria while antagonistic drug pairs would reverse the trend especially when targeting bacterial strains with a combination of drugs of unknown interactions.

Abstract: Adenophora (Campanulaceae) is a perennial herbs and diverse genus, which occurs mainly in eastern Asia, particularly in China. Due to the complex morphological variation and overlapping geographic distribution, the delimitation and systematic arrangement of the species within this genus are still on debate. In this study, we assessed the species discriminating power of four standard DNA barcodes (rbcL, matK and trnH-psbA from chloroplast genome and ITS from nuclear genome) on the basis of 30 accessions of nine Adenophora species obtained mainly from China. The results showed that all four barcodes can be easily amplified and sequenced with the currently established primers, but we did not find any distinct barcoding gaps in the distributions of any marker, and none of the single or combined markers achieved high species discrimination (11.1% – 44.4%), indicating the effectiveness of the standard DNA barcodes for species identification in Adenophora was very limited. Meanwhile, a phylogenetic analysis was performed for about 70% of the representatives of Adenophora based on ITS sequences. None of the two sections of Adenophora were monophyletic, and the topologies obtained do not suggest a new division for the genus.

Abstract: PVC (Photovoltaic Cell) is a semiconductor device; generally it is PN type semiconductor device. PVC plays a vital role in the generation connected with electricity. There are three types of PVC, mainly organic, inorganic and hybrid. Mostly customers complain that their PVC is not creating electricity with greater speed and efficiency. Another problem is related with the PVC is its weight time as well as less presence under sunlight in the hours of daylight. The aim of this study is always to address the aforementioned problems related to PVC. Our team proposes two main solutions with this Respect to the effects of artificial light on a replacement of the sunlight is the use of solar spectrum on solar cells for strong light with wavelength providing and second one is Plano-convex lens to concentrate on the yellow light bulb in a dark room to improve the rate of photon emission. It passes then describes the installation of solar energy technique simulation in addition to execution and as well as gave some predictions around the future electricity generated improves.

Abstract: The present investigation revealed Botryodiplodia theobromae, Aspergillus niger, Aspergillus flavus and Aspergillus glaucus as causes of post-harvest rot disease of yam tubers on the bases of pathogenicity test. Hot extracts of 10g, 30g and 50g /100ml of Chromolaena odorata inhibited Aspergillus flavus to 92.19%, 92.19% and 97.77% respectively, while 20g and 40g/100ml inhibited Aspergillus glaucus to 95.56% and 92.22% respectively. 10g, 40g and 50g/100ml of cold extract of C. odorata inhibited Aspergillus niger to 98.08%, 96.69% and 96.92% while 20g/100ml concentration inhibited B. theobromae to 96.86% and the least inhibited being Aspergillus flavus (93.31%). 30g and 40g/100ml concentration of C. odorata inhibited Aspergillus flavus to 89.97% and 98.89% respectively, while Aspergillus niger (96.16%) was least inhibited. Cold aqueous extract of C. odorata at 50g/100ml inhibited B theobromae by 95.24%. Both hot and cold extracts of C. odorata were found to be very potent against yam tuber rot pathogens. These serve as preferred alternatives to chemicals which usually have negative effects on the environment.

Abstract: Objective: To assess the involvement of C3-C4 and CRP in the pathophysiology of childhood bronchial asthma. Method: Selection of the patients (n=40) was made according to the recommended international criteria for diagnosis of asthma. Serum levels of C3, C4 and CRP were measured by radio immunodiffusion technique in 40 Libyan, non obese, children between (4-12 years), sex: 26 males, 14 females, with mild to moderately severe asthma, all patients were in active disease and on preventive therapy. Age matched comparisons were made with 28 healthy non obese children between (4-12years), sex: 13 males and 15 females. Results: Mean C3 level and C4 level were not significantly changed in non obese asthmatic children as compared to controls (p>0.05). The level of C-reactive protein was higher in asthmatic children than normal children (P>0.05) in all age groups. The serum level of C3, C4 are non significantly changed in non obese asthmatic children with positive correlation between C3, C4 levels. The level of C3-C4 was not significantly changed, possibly due to all asthmatic non obese patients being in inactive disease possibly to lack of induction of pro inflammatory cytokins and interlukin 1 (IL-1). CRP may be a potential indirect marker of asthma severity and control, as so can be used to assess the grade of inflammation in asthmatic patient (11) as inflammation is one of the major characteristics of respiratory allergy diseases.

Abstract: Microcystins (MCs) are produced by cyanobacteria in natural environments, which have more than 90 different congeners. One of the most toxic and thoroughly studied microcystins is microcystin-LR (MC-LR), which can increase the risk of hepatotoxicity, neurotoxicity, reproduction toxicity, cytotoxicity and respiratory diseases by accumulating in the body. This review focuses on respiratory toxicity of microcystins. Pulmonary injury after acute or sub-chronic exposure to different doses of microcystins are summarized. However, further studies are needed to clarify the signaling pathways of respiratory toxicity of microcystins.

Abstract: Even though the prevention of fungal growth is still the good practice to prevent contamination by mycotoxins, but there are a number of approaches that can be taken to minimize mycotoxins contamination in the food. The advantage of using-plant produced compounds and bioagent as a source of safer and more effective control substances than synthetically produced antimicrobial agents can be demonstrated both practically and in terms of consumer acceptance. Cinnamon and cyperus oils had antifungal activity against Alternaria alternata and Fusarium culmorum. Inhibition % of deoxynivalenol (DON) and Trichothecene (T-2) production was 21.89 and 42.83% respectively at 1.5 L/ml of cinnamon oil. The extracts of the Aloe vera inhibit the production of Zearalenone and T-2 mycotoxins ranged from 9.13 to 17.15 and from 33.10 to 36.69% respectively. Strong effective of Adenium obesum extract on the inhibition production of ZER, DON and T-2 mycotoxins was reported, inhibition% was 39.15, 43.92 and 45.00 % at 20, 5 and 20 mg/ml respectively. Decrease of ZEA, DON and T-2 mycotoxins levels in comparison with the control (1083.43, 77.03 and 497.67 g/kg respectively) was observed with Saccharomyces cerevisiae interaction (659.90, 42.92 and 294.26g/kg respectively). T. harzianum inhibited the production of ZEA, DON and T-2 mycotoxins with an average inhibition of 25.06, 33.01 and 50.55% respectively. Our results improved that, the tested T. harzianum and S.cerevisiae had no toxic effects, seems to be a highly promising agent in preventing food contamination with F.culmorum and greatly inhibit mycotoxin production in vitro.

Abstract: MicroRNA (miRNA) are small non coding RNAs of~22nt in length that are primarily transcribed from primary RNA (pri-miRNA). The signatures of these miRNA are their secondary hairpin structure with bulge in stem region. miRNA molecules are involved in RNA interference mechanism and control gene expression by targeting mRNA. miRNA mostly targets at 3’untranslated region of gene and controls protein production by translational repression or mRNA degradation. The undesirable production of miRNA is substantial factor in many human diseases. Several miRNAs are reported that are associated with human diseases. EBV miRNA is associated with various diseases like Gastric Carcinoma, nasopharyngeal, Lymphoblastoid, lymphoma and other diseases. Identification of conserved EBV miRNA in Rhesus Lymphocryptovirus (RLCV) that infects monkey can be helpful in better understanding of human diseases and its pathological conditions for drug development process for Epstein Barr Virus. In this paper we have done phylogenetic analysis of miRNA among 12 different viruses study shows that there is functional relationship between Epstein Barr Virus and Rhesus Lymphocryptovirus, sharing 21 clades with a confidence bootstrap value from 80-100%. Structural alignment of EBV and RLV miRNA shows functional similarity of EBV miRNAs and a consensus miRNA is designed to study conservational motifs of these miRNA. This study signifies the potential role RLCV miRNA as model molecule to study EBV infection in human and molecular diagnosis of many human diseases associated with EBV miRNA.

Abstract: Objective: To investigate the value of ultrasound in the diagnosis of rheumatoid arthritis (RA), and to provide objective data for the early diagnosis and treatment of rheumatoid arthritis. Method: 64 cases of patients with rheumatoid arthritis, 30 cases of normal control group, were examined by color Doppler ultra-diagnostic instrument, probe frequency 7.5 ~ 15.0MHz The value and application of ultrasound in patients with RA were observed and compared with the normal group. Results: 64 cases of RA patients with knee joint ultrasound images can show clearly the five kinds of pathological changes; 1 knee joint synovial membrane thickening, 2 bursa effusion, 3 sheath thickening, 4.CDFI grade increased 5. Five kinds of pathological changes of bone destruction with the healthy control group were statistically significant (P<0.05, respectively); According to the pathological changes of the knee joint ultrasound images and the corresponding clinical manifestations of the knee, can be more clearly the RA induced knee lesions were divided into mild (I degrees), moderate (II degrees) and severe (III degrees). And also according to the pathological changes of the knee joint ultrasound images, the severity of the pathological changes of RA patients was found to be independent of the age of the patients, and there was a significant correlation with the history of the patients, and the correlation coefficient was close to 1. Conclusion: 1The routine assistant diagnosis in RA with X-ray would be replaced with ultrasound 2the correlation between the five pathological changes and pathological changes of the knee joint in patients with ultrasound RA and the length of history, and according to the clinical manifestations of RA patients with ultrasound images of the knee joint and the corresponding knee, the pathological changes of knee joint were divided into mild gradeI degree, moderate grade (II degree) and severe grade (III degree), in order to clear and convenient for RA clinical diagnosis, treatment and research. 3) To define the change of the knee joint of RA patients with 1-16 and the characteristics of the positive correlation with the history of RA. At the same time, it also suggested that there is no obvious clinical effect on RA in the diagnosis and treatment, to strengthen the pathogenesis, diagnosis and treatment of RA is still the goal and direction of the efforts of governments and medical science and technology personnel all over the world.
