Joint strength of friction stir welded AISI 304 austenitic stainless steels
Authors: Meran Cemal , Canyurt Olcay Ersel 
Published: September 2013

Abstract
In this study, AISI 304 (X5CrNi18-10) austenitic stainless steels were joined by means of friction stir welding. The welded joint strength of stainless steels was influenced by many factors, such as different tool rotational speeds, traverse speeds, compressive tool forces, and tool angles, etc. There is a strong interrelation among the friction stir welding design parameters. The effects of design parameters on the welded joint were analyzed using a genetic algorithm. Appropriate design parameter configurations led to fine-grained microstructures that resulted in higher tensile strength joints compared to the base material. The best design configuration that led to 1.16 times higher strength than the base material was achieved with 47.5 mm min−1 traverse speed, a rotational speed of 1 180 min−1, compressive tool force of 7 kN and tool tilt angle of 2.0°.
An investigation of the microstructure and hydrogenation/dehydrogenation properties of ball-milled CeMg12 alloys with Ni powders
Authors: Feng Hu , Yanghuan Zhang , Yin Zhang , Jianyi Xu , Ying Cai , Leibo Deng 
Published: September 2013

Abstract
CeMg12 + 100 wt.% Ni composite hydrogen storage alloys were prepared using ball-milling. The phase structure, morphologies, and hydrogen absorption and desorption kinetics of these alloys were systematically investigated. The results show that the milled CeMg12 + 100 wt.% Ni alloys consisted of Mg2Ni and Ni phase with nanocrystalline and amorphous structures. Additionally, the volume fractions of the phase increased with prolonged ball-milling times, which improved the hydrogenation rates and the hydrogen storage capacities of the alloy samples. However, the dehydrogenation kinetics of the alloy samples were also impaired by the increased milling times. The poor dehydriding kinetics of the alloy samples milled for 80 h and 100 h were primarily attributed to grain size effects.

Authors: He Hong-wei , Gao Feng , Li Kai-xi 
Published: September 2013

Abstract
Previously, we have shown that the effects of the coating solution concentration of coupling agent on the interlaminar shear strength of fiber/epoxy composites were best investigated with 4 wt.% nano-CaCO3 content. Here, five different types of composites were prepared: (E–0–4): composites modified by untreated nano-CaCO3, (E–1.1–4): composites modified by nano-CaCO3 with 1.1 wt.% coating solution concentration treatment. Similarly, samples E–2.3–4, E–3.5–4 and E–4.6–4 were also fabricated. The results show that nanocomposites prepared with 2.3 wt.% and 3.5 wt.% coating solution concentration treatment have the best shear properties, including interlaminar shear strength, elongation at break and fracture work. With 2.3 wt.% coating solution concentration treatment, these have values of 142.4 MPa, 1.95 mm and 1.86 J, which can increase 11%, 41% and 39% compared to the composite prepared with untreated nano-CaCO3, respectively.

Dung beetles (Coleoptera: Scarabaeidae) associated with cattle dung on native grasslands of southern Alberta, Canada
Authors: Floate K.D. , Kadiri N. 
Published: September 2013

AbstractSurveys of dung beetles establish the dominance of exotic taxa associated with cattle dung on native grasslands in southern Alberta, Canada. Of the 12 species recovered, eight were of European origin and comprised 92.2% of the total catch of 187 963 beetles. Most common wereChilothorax distinctus(Müller),Onthophagus nuchicornis(Linnaeus), andColobopterus erraticus(Linnaeus) (Coleoptera: Scarabaeidae). The abundance ofC. distinctushas been known in the region since the 1920s, whereas that ofO. nuchicornisonly was first reported in the 1990s. The abundance ofC. erraticushas not previously been observed in the region and identifies the species as the newest addition to the endemic fauna. The diversity of native species on pastures in southern Canada and adjacent states is depauperate, such that the establishment of European taxa has appreciably increased levels of bioturbation in pasture ecosystems. The success of these exotic species on northern pastures may reflect a level of cold-tolerance greater than that of most native species.

Published: September 2013

BACKGROUND: Lower respiratory tract infections (LRTI) account for a considerable proportion of morbidity and antibiotic use. We aimed to identify the causative bacteria, antibiotic sensitivity and resistance of hospitalized adult patients due to LRTI in Upper Egypt. METHODS: A multicentre prospective study was performed at 3 University Hospitals for 3 years. Samples included sputum or bronchoalveolar lavage (BAL) for staining and culture, and serum for serology. Samples were cultured on 3 bacteriological media (Nutrient, Chocolate ,MacConkey's agars).Colonies were identified via MicroScan WalkAway-96. Pneumoslide IgM kit was used for detection of atypical pathogens via indirect immunofluorescent assay. RESULTS: The predominant isolates in 360 patients with CAP were S.pneumoniae (36%), C. pneumoniae (18%), and M. pneumoniae (12%). A higher sensitivity was recorded for moxifloxacin, levofloxacin, macrolides, and cefepime. A higher of resistance was recorded for doxycycline, cephalosporins, and β-lactam-β-lactamase inhibitors. The predominant isolates in 318 patients with HAP were, methicillin-resistant Staphylococcus aureus; MRSA (23%), K. pneumoniae (14%), and polymicrobial in 12%. A higher sensitivity was recorded for vancomycin, ciprofloxacin, and moxifloxacin. Very high resistance was recorded for β-lactam-β-lactamase inhibitors and cephalosporins. The predominant organisms in 376 patients with acute exacerbation of chronic obstructive pulmonary diseases (AECOPD) were H. influnzae (30%), S. pneumoniae (25%), and M. catarrhalis(18%). A higher sensitivity was recorded for moxifloxacin, macrolides and cefepime. A higher rate of resistance was recorded for aminoglycosides and cephalosporinsCONCLUSIONS: The most predominant bacteria for CAP in Upper Egypt are S. pneumoniae and atypical organisms, while that for HAP are MRSA and Gram negative bacteria. For acute exacerbation of COPD,H.influnzae was the commonest organism. Respiratory quinolones, macrolides, and cefepime are the most efficient antibiotics in treatment of LRTI in our locality.
PROTEOLYTIC PROCESSING OF VON WILLEBRAND FACTOR BY ADAMTS13 AND LEUKOCYTE PROTEASES
Authors: Lancellotti Stefano , Basso Maria , De Cristofaro Raimondo 
Published: September 2013

ADAMTS13 is a 190 kDa zinc protease encoded by a gene located on chromosome 9q34. This protease specifically hydrolyzes von Willebrand factor (VWF) multimers, thus causing VWF size reduction. ADAMTS13 belongs to the A Disintegrin And Metalloprotease with ThromboSpondin type 1 repeats (ADAMTS) family, involved in proteolytic processing of many matrix proteins. ADAMTS13 consists of numerous domains including a metalloprotease domain, a disintegrin domain, several thrombospondin type 1 (TSP1) repeats, a cysteine-rich domain, a spacer domain and 2 CUB (Complement c1r/c1s, sea Urchin epidermal growth factor, and Bone morphogenetic protein) domains. ADAMTS13 cleaves a single peptide bond (Tyr1605-Met1606) in the central A2 domain of the VWF molecule. This proteolytic cleavage is essential to reduce the size of ultra-large VWF polymers, which, when exposed to high shear stress in the microcirculation, are prone to form with platelets clumps, which cause severe syndromes called thrombotic microangiopathies (TMAs). In this review, we a) discuss the current knowledge of structure-function aspects of ADAMTS13 and its involvement in the pathogenesis of TMAs, b) address the recent findings concerning proteolytic processing of VWF multimers by different proteases, such as the leukocyte-derived serine and metallo-proteases and c) indicate the direction of future investigations

Published: September 2013

SummaryThe Journal of Health Informatics in Developing Countries was established to meet a perceived need for Health Informaticians in developing countries to be able to share the results of their research in an affordable and easy-to-access online publication. The journal was developed using the open source platform “Open Journal System,” and has now published 67 articles across 13 issues. A collaborative editorial approach has been established to address the problems of limited research budgets, difficulties with translating to English and other problems specific to authors from developing countries. The journal faces many challenges including ensuring future financial sustainability and inclusion in journal indexing systems. However, the continuing support of an international body of Associate Editors and Editorial Board Members has enabled a wide range of useful and informative health informatics research to be disseminated across the developing world.
Changes in Vertical Dimension of Complete Dentures due to Rebasing with Different Techniques
Authors: Mohammed Shammas , Alla Rama Krishna , Devarhubli Achut , Shakeel SK 
Published: September 2013

ABSTRACTDental literature is devoid of information in respect of altered incisal pin relation due to compression molding in a single denture. It is to be reckoned that in rebasing technique, the entire segment of teeth remain fixed through a matrix of set polymethylmethacrylate that binds all the teeth. Thus, the artificial teeth do not remain as individual but act as a single unified unit of all the teeth. In view of lack of information in change in vertical dimension due to rebasing procedures and with the aim of determining the method of rebasing that result in minimal changes in occlusal discrepancy, the study was undertaken to evaluate the changes in vertical dimension of occlusion after rebasing using two different methods.How to cite this articleMohammed S, Alla RK, Devarhubli A, Shakeel SK.

Microleakage: Apical Seal vs Coronal Seal
Authors: Amlani Harsh 
Published: September 2013

ABSTRACT
Microorganisms can reach the dental pulp through the open cavity, dentinal tubules, gingival sulcus, periodontal ligament through a broken occlusal seal or faulty restoration of tooth previously treated by endodontic therapy or extension of a periapical infection from adjacent infected teeth. During operative procedures, these possible paths must be considered to prevent ingress. While endodontic therapy is being performed, these paths must be blocked to avoid contamination during and after the treatment. Well treated tooth might also fail if microorganisms reach the periradicular tissues. After root canal obliteration, care must be taken to ensure maintenance of the coronal as well as apical seal from contaminants.

Craniofacial Anomalies: A Proactive Approach for the Dental Practitioner
Authors: Umasankar K , Jawaharlal Nagalakshmi 
Published: September 2013

ABSTRACT
Congenital malformations have seen a steep increase over recent years. Facial defects too have increased five-fold as a consequence. As dentists grapple with treating such defects, a simple model for prenatal identification of potential risks and counseling coupled with referral and a communication model is presented. With no start-up costs and zero investment in terms of money, such sensitization is expected to be the platform for reduction in congenital facial defects due to education and optimized treatment. Teledentistry, internet and clinical research are cited as tools for effective reduction in birth defects.

Authors: Khoroushi Maryam , Fathpour Kamyar 
Published: September 2013

ABSTRACTIntroductionTrichloroacetic acid (TCA) is a soft tissue cauterizing agent applied to gingival margins prior to cervical tooth-colored restorations. The presentin vitrostudy evaluated the effects of two different concentrations of TCA hydrogel as a hemostatic/preconditioning agent on the shear bond strength (SBS) of a self-etch adhesive to tooth structures.Materials and methodsThirty-six flat enamel and 36 flat dentin surfaces were prepared using human molars; each group was subdivided into three subgroups (n = 12). The groups were made ready as follows: In groups 1 (E1 and D1), the enamel (E) and dentin (D) surfaces were designated as control groups and remained intact. In groups 2 (E2 and D2), 35% TCA gel was applied to enamel and dentin surfaces for 30 seconds. In groups 3 (E3 and D3), 50% TCA gel was applied to enamel and dentin surfaces for 30 seconds. Clearfil SE Bond and Z100 composite resin were applied to the surfaces according to manufacturers¡¦ instructions. After 24 hours of incubation and thermocycling, the composite cylinders underwent an SBS test in a DARTEC test machine. Data were analyzed using the ANOVA and Scheffé's test (α = 0.05).ResultsThe mean SBS ± SD in the study groups were 34.73 ± 5.66, 35.32 ± 7.3, 23.75 ± 9.67, 20.94 ± 9.84, 19.32 ± 6.20, 23.50 ± 6.63 MPa in the E1, E2, E3, D1, D2 and D3 groups, respectively. ANOVA revealed significant differences between the SBS values of enamel groups (p = 0.001). There were no significant differences between the dentin groups (p = 0.425).ConclusionApplication of 35 and 50% concentrations of TCA to dentin had no detrimental effect on the bond produced by two-step self-etch adhesive under study; however, application of only 35% TCA to enamel did not result in a detrimental effect on the same adhesive.How to cite this articleFathpour K, Khoroushi M.

Authors: Aslam Sachin , Francis PG , Rao BHS , Ummar M , Issac JK , Nair RB 
Published: September 2013

ABSTRACT

Aim
The present double blind study has been designed to evaluate the efficacy of local application of hemocoagulase solution as compared to a placebo in wound healing following dental extraction.

Materials and methods
A total of 20 patients who required dental extraction for orthodontic intervention were included. The hemocoagulase solution and a placebo were locally applied to the extraction sockets and the efficacy of the solution in terms of bleeding control, anti-inflammatory responses, its antiseptic properties and efficacy in wound healing were evaluated.

Results
The mean time required to achieve hemostasis was found to be 1.37 minutes in side A (test) and 2.33 minutes in side B (control) indicating that side A achieved faster hemostasis when compared to side B. At the 6th hour postoperatively, bleeding was not evident on either sides, and the amount of pain in side A was found to be less compared to side B. The number of RBCs, polymorphs, chronic inflammatory cells were not different in both the groups, whereas at 3rd postoperative day epithelial cells were greater in side A (test) compared to side B (control). Biopsy reports on the 12th postoperative day indicated that the number of fibroblasts, epithelial cells, collagen count was found to be greater in side A (test) compared to side B (control).

Conclusion
The topical hemocoagulase solution may be advocated in the field of oral and maxillofacial surgery, as a hemostatic agent and promoter of wound healing. However, further studies, with large number of cases and different clinical situations should be considered to authenticate the efficacy of this hemocoagulase solution in the practice of oral and maxillofacial surgery.

Clinical significance
Wound healing plays an important role in the success of any surgical procedure, such as extractions, and the hemocoagulase system may act as a hemostatic agent and a promoter of wound healing.

ImportanceEndometriosis has been associated with an increased risk of ovarian cancer; however, the associations between endometriosis subtypes and ovarian cancer histotypes have not been well-described.ObjectiveTo evaluate the associations of endometriosis subtypes with incidence of ovarian cancer, both overall and by histotype.Design, Setting, and ParticipantsPopulation-based cohort study using data from the Utah Population Database. The cohort was assembled by matching 78 893 women with endometriosis in a 1:5 ratio to women without endometriosis.ExposuresEndometriosis cases were identified via electronic health records and categorized as superficial endometriosis, ovarian endometriomas, deep infiltrating endometriosis, or other.Main Outcomes and MeasuresEstimated adjusted hazard ratios (aHRs), adjusted risk differences (aRDs) per 10 000 women, and 95% CIs for overall ovarian cancer, type I ovarian cancer, and type II ovarian cancer comparing women with each type of endometriosis with women without endometriosis. Models accounted for sociodemographic factors, reproductive history, and past gynecologic operations.ResultsIn this Utah-based cohort, the mean (SD) age at first endometriosis diagnosis was 36 (10) years. There were 597 women with ovarian cancer. Ovarian cancer risk was higher among women with endometriosis compared with women without endometriosis (aHR, 4.20 [95% CI, 3.59-4.91]; aRD, 9.90 [95% CI, 7.22-12.57]), and risk of type I ovarian cancer was especially high (aHR, 7.48 [95% CI, 5.80-9.65]; aRD, 7.53 [95% CI, 5.46-9.61]). Ovarian cancer risk was highest in women with deep infiltrating endometriosis and/or ovarian endometriomas for all ovarian cancers (aHR, 9.66 [95% CI, 7.77-12.00]; aRD, 26.71 [95% CI, 20.01-33.41]), type I ovarian cancer (aHR, 18.96 [95% CI, 13.78-26.08]; aRD, 19.57 [95% CI, 13.80-25.35]), and type II ovarian cancer (aHR, 3.72 [95% CI, 2.31-5.98]; aRD, 2.42 [95% CI, −0.01 to 4.85]).Conclusions and RelevanceOvarian cancer risk was markedly increased among women with ovarian endometriomas and/or deep infiltrating endometriosis. This population may benefit from counseling regarding ovarian cancer risk and prevention and could be an important population for targeted screening and prevention studies.
