Distribution of lower urinary tract symptoms (LUTS) in adult women
OBJECTIVE: To determine the distribution of lower urinary tract symptoms in adult women and the frequency with which the women consulted a health care provider for their symptoms. DESIGN: Cross-sectional analytical study. PLACE AND DURATION OF STUDY: Community Health Center of Aga Khan University Hospital from November 1st to 30th, 2002. SUBJECTS AND METHODS: A trained interviewer administered a structured questionnaire to women patients or attendants aged 18 years and older coming to the center. RESULTS: Fifty-two percent of the study subjects reported having at least one or more urinary complaints in the past. Stress incontinence was the highest reported complaint (38.4%) followed by burning (34.4%), frequency (26%), painful micturition (20.4%), urge incontinence (18.8 %), incomplete emptying of bladder (14.4%), dribbling (12.4%) and poor stream (8.4%). Forty-three percent of the women with LUTS never consulted a health care provider for their problem.CONCLUSION: Although the distribution of LUTS among females was found to be high, the patients did not consider it important enough to consult a health care provider. There is a need to create awareness among females regarding LUTS and the need to consult a health care provider for their problems
Anticoagulant potential and total phenolic content of six species of the genus Ficus from Azad Kashmir, Pakistan
Purpose: To investigate the total phenolic and flavonoid contents of Ficus benghalensis, Ficus elasticaa, Ficus palmata, Ficus religiosa, Ficus semicordata and Ficus auriculata, and to determine their anticoagulant potential.
Methods: Crude methanol extracts were prepared from the plant leaves, and fractionated using liquidliquid partition with n-hexane, chloroform and ethyl acetate. The total flavonoid and total phenolic contents of the extracts and their fractions were determined. The anticoagulant potential of the six Ficus species were evaluated in healthy human plasma, using activated partial thromboplastin time (APTT) and prothrombin time (PT) methods.
Results: Phytochemical analysis showed the presence of considerable amounts of flavonoids ranging from 5.3 ± 0.7 to 11.8 ± 0.3 mg rutin equivalents (RE)/g, and phenolic compounds ranging from 8.0 ± 0.7 to 86.5 ± 1.5 mg gallic acid equivalents (GAE)/g in each fraction of the six species. Results from in vitro anticoagulant potential assays showed significant anticoagulant properties, with prothrombin time (PT) ranging from 17.7 ± 0.7 to 26.7 ± 2.2 s, and activated partial thromboplastin time (APTT) varying from 47.7 ± 3.3 to 72.3 ± 5.4 s.
Conclusion: The results indicate that F. semicordata and F. Religiosa have higher anticoagulant potential than the other Ficus species studied
Female Dental Student’s Perception of Their Dental Aesthetics and Desired Dental Treatment
Objectives: This study aims to assess the self-perception of female dental students of their dental aesthetics regarding their satisfaction, its effect on their quality of life and felt need for treatment. Materials and Method: This is a descriptive study for 1st, 2nd and 3rd year dental students (n=110) in the College of Dentistry at Princess Nourah University (PNU). The survey was distributed via link "Google form". A 20 item questionnaire was prepared and tested before on seven students for clarity. Questions were regarding how students feel about their dental aesthetics and what they desire for treatment. Whether they felt their teeth affected their attractiveness, confidence and quality of life. Data was entered in SPSS for statistical analysis. Results: With a response rate of 94.5% majority (89.4%) of students felt their teeth affected the attractiveness of their faces. Almost one third (30.8%) have tried to hide their smile. Around half (51%) were not satisfied with their tooth colour. Almost two thirds of students (61.5%) felt their quality of life is affected by the appearance of their teeth. ‘Tooth whitening’ was selected by almost two thirds of students (64.4%) followed by almost half (46.2%) the students wanting ‘orthodontic treatment’. Conclusion: Dental aesthetics is rated highly among female dental students.The majority of the students felt that their teeth affected the attractiveness of their face and influenced their quality of life. Students desired teeth whiteneing followed by orthodontic treatment as their perceived need for aesthetic dental treatments
3D-QSPR Method of Computational Technique Applied on Red Reactive Dyes by Using CoMFA Strategy
Cellulose fiber is a tremendous natural resource that has broad application in various productions including the textile industry. The dyes, which are commonly used for cellulose printing, are “reactive dyes” because of their high wet fastness and brilliant colors. The interaction of various dyes with the cellulose fiber depends upon the physiochemical properties that are governed by specific features of the dye molecule. The binding pattern of the reactive dye with cellulose fiber is called the ligand-receptor concept. In the current study, the three dimensional quantitative structure property relationship (3D-QSPR) technique was applied to understand the red reactive dyes interactions with the cellulose by the Comparative Molecular Field Analysis (CoMFA) method. This method was successfully utilized to predict a reliable model. The predicted model gives satisfactory statistical results and in the light of these, it was further analyzed. Additionally, the graphical outcomes (contour maps) help us to understand the modification pattern and to correlate the structural changes with respect to the absorptivity. Furthermore, the final selected model has potential to assist in understanding the charachteristics of the external test set. The study could be helpful to design new reactive dyes with better affinity and selectivity for the cellulose fiber
Role of copper and alumina for heat transfer in hybrid nanofluid by using Fourier sine transform
The convection, thermal conductivity, and heat transfer of hybrid nanofluid through nanoparticles has become integral part of several natural and industrial processes. In this manuscript, a new fractionalized model based on hybrid nanofluid is proposed and investigated by employing singular verses and non-singular kernels. The mathematical modeling of hybrid nanofluid is handled via modern fractional definitions of differentiations. The combined Laplace and Fourier Sine transforms have been configurated on the governing equations of hybrid nanofluid. The analytical expression of the governing temperature and velocity equations of hybrid nanofluid have been solved via special functions. For the sake of thermal performance, dimensional analysis of governing equations and suitable boundary conditions based on Mittage-Leffler function have been invoked for the first time in literature. The comparative analysis of heat transfer from hybrid nanofluid has been observed through Caputo-Fabrizio and Atangana-Baleanu differential operators. Finally, our results suggest that volume fraction has the decelerated and accelerated trends of temperature distribution and inclined and declined profile of heat transfer is observed copper and alumina nanoparticles
Assessment of Genetic Diversity and Population Structure in a Global Reference Collection of 531 Accessions of Carthamus tinctorius L. (Safflower) Using AFLP Markers
Carthamus tinctorius L. (safflower) is an important oilseed crop that is cultivated in several countries. The present study investigates the genetic diversity and population structure of 531 safflower accessions from 43 countries representing all safflower growing regions of the world. Diversity analysis was performed using ten informative EcoRI/MseI amplified fragment length polymorphism primer pairs that were identified by screening 150 primer combinations. The selected primer pairs generated 381 fragments of which 157 were polymorphic among the analyzed accessions. The genetic diversity indices obtained for the entire collection (I = 0.4536, H = 0.2955) indicated high levels of molecular variability. The distance-based, neighbor-joining method classified the accessions into six clusters with internal subgroupings that were in consonance with 19 clusters obtained using Bayesian model-based BAPS analysis. Clusters obtained through STRUCTURE analysis (at K = 4) could not be correlated with their geographically diverse origins, while BAPS analysis (at K = 19) revealed geographical delineation with low admixture levels among most of the studied accessions. Accessions from Far East and Egypt clustered in distinct groups, indicating conserved nature of their gene pools. The Near East and Iran–Afghanistan regions were collectively found to harbor maximum diversity in accordance with earlier reports. Accessions from the Indian subcontinent showed substantial diversity that was previously undetected. The American accessions showed low molecular variability in contrast to earlier studies. Genetic sub-structuring within gene pools and inter-relationships between accessions belonging to different regional pools was also observed. To the best of our knowledge, this is the first comprehensive study of existing genetic variability in a large collection of safflower germplasm with a global distribution, which provides a more accurate representation of genetic structuring in the crop. This information will facilitate selection of elite genotypes for broadening the genetic base of various breeding programs in safflower
Development of Genomic Microsatellite Markers in Carthamus tinctorius L. (Safflower) Using Next Generation Sequencing and Assessment of Their Cross-Species Transferability and Utility for Diversity Analysis
Background
Safflower (Carthamus tinctorius L.), an Asteraceae member, yields high quality edible oil rich in unsaturated fatty acids and is resilient to dry conditions. The crop holds tremendous potential for improvement through concerted molecular breeding programs due to the availability of significant genetic and phenotypic diversity. Genomic resources that could facilitate such breeding programs remain largely underdeveloped in the crop. The present study was initiated to develop a large set of novel microsatellite markers for safflower using next generation sequencing.
Principal Findings
Low throughput genome sequencing of safflower was performed using Illumina paired end technology providing ~3.5X coverage of the genome. Analysis of sequencing data allowed identification of 23,067 regions harboring perfect microsatellite loci. The safflower genome was found to be rich in dinucleotide repeats followed by tri-, tetra-, penta- and hexa-nucleotides. Primer pairs were designed for 5,716 novel microsatellite sequences with repeat length ≥ 20 bases and optimal flanking regions. A subset of 325 microsatellite loci was tested for amplification, of which 294 loci produced robust amplification. The validated primers were used for assessment of 23 safflower accessions belonging to diverse agro-climatic zones of the world leading to identification of 93 polymorphic primers (31.6%). The numbers of observed alleles at each locus ranged from two to four and mean polymorphism information content was found to be 0.3075. The polymorphic primers were tested for cross-species transferability on nine wild relatives of cultivated safflower. All primers except one showed amplification in at least two wild species while 25 primers amplified across all the nine species. The UPGMA dendrogram clustered C. tinctorius accessions and wild species separately into two major groups. The proposed progenitor species of safflower, C. oxyacantha and C. palaestinus were genetically closer to cultivated safflower and formed a distinct cluster. The cluster analysis also distinguished diploid and tetraploid wild species of safflower.
Conclusion
Next generation sequencing of safflower genome generated a large set of microsatellite markers. The novel markers developed in this study will add to the existing repertoire of markers and can be used for diversity analysis, synteny studies, construction of linkage maps and marker-assisted selection
