A new phantom to evaluate the tissue dissolution ability of endodontic irrigants and activating devices

Objective@#The aim of this study was to introduce a gelatin/bovine serum albumin (BSA) tissue standard, which provides dissolution properties identical to those of biological tissues. Further, the study evaluated whether the utilization of endodontic activating devices led to enhanced phantom dissolution rates. @*Materials and Methods@#Bovine pulp tissue was obtained to determine a benchmark of tissue dissolution. The surface area and mass of samples were held constant while the ratio of gelatin and BSA were varied, ranging from 7.5% to 10% gelatin and 5% BSA. Each sample was placed in an individual test tube that was filled with an appropriate sodium hypochlorite solution for 1, 3, and 5 minutes, and then removed from the solution, blotted dry, and weighed again. The remaining tissue was calculated as the percent of initial tissue to determine the tissue dissolution rate. A radiopaque agent (sodium diatrizoate) and a fluorescent dye (methylene blue) were added to the phantom to allow easy quantification of phantom dissolution in a canal block model when activated using ultrasonic (EndoUltra) or sonic (EndoActivator) energy. @*Results@#The 9% gelatin + 5% BSA phantom showed statistically equivalent dissolution to bovine pulp tissue at all time intervals. Furthermore, the EndoUltra yielded significantly more phantom dissolution in the canal block than the EndoActivator or syringe irrigation. @*Conclusions@#Our phantom is comparable to biological tissue in terms of tissue dissolution and could be utilized for in vitro tests due to its injectability and detectability.

Detection of virulence genes and investigation of the immunogenicity of outer membrane proteins of Salmonella enterica

Salmonella enterica is one of the most important food-borne pathogens, causing a variety of diseases in humansand animals. This study aimed to detect the virulence genes in 33 S. enterica strains isolated from patients andto investigate the immunogenicity of the outer membrane proteins (OMPs) of S. enterica serovar Typhimurium.The aggregative fimbriae (agfA) gene was detected in all S. enterica isolates except one strain, SalmonellaParatyphi C strain SA7. In addition, 81.8% of the isolates harbored the sefC gene (fimbrial protein). However,all of the tested S. enterica isolates possessed the fimA, hilA, invA, stn, and misL virulence genes, regardless ofserovar. The predominant OMPs of S. enterica Typhimurium SA3 identified by 12% sodium dodecyl sulfatePolyacrylamide Gel Electrophoresis (PAGE) were used as eliciting antigens in the experimental mice. Theresults of the protection studies indicated that the selected OMPs conferred varying degrees of protection.However, the highest protection was observed using the 38-kDa OMP, which provided 100% protection tomice challenged with 50× LD50 of Salmonella Typhimurium SA3 and 75% protection to mice subjected toan even higher bacterial challenge of 100× LD50. The humoral response in mice caused by the 38-kDa OMPwas confirmed using an immunodiffusion assay. This 38-kDa OMP is a promising candidate for the vaccinedevelopment against S. enterica Typhimurium. Further research on the protein structure was recommended.

Backache: Association with Stature, Posture and Work-Station Ergonomics in Information Technology Professionals-An Analytical Study

The Information technology has been the bane of contention in the present scenario and has been an inevitable part of thelife of every citizen in the society. With the improvement in communication, it has brought many health related problems andone among them is the backache. The main aim of the study was to examine the association between the stature, posture andwork-station Ergonomics in Information Technology Professionals. One hundred IT professional who had more than 3 yearsof work experience aged between 20-30 years were surveyed. The anthropometric and workstation measurement werestature, height of tabletop, angle of backrest, position of knees, sitting posture, presence or absence of footrest. The resultsshowed that persons with height of less than 163 cm (21%) and more than 170 cm (72%) suffered backache. Butprofessionals with a height range of 164-169 cm suffered 7% due to many factors. It was concluded that a table top of 75 cmwas recommended to persons with all heights which may greatly reduce the risk of backache in the IT professionals.

Fatigue: Impact of Muscular Co-Ordination among Rifle Shooters

It has been well reported that fatigue is an important factor which hinders performance. The resultant effect of it is loss ofco-ordination and efficiency. The main aim of this investigation was to find out the effect of fatigue on muscular coordination among rifle shooters. Ten rifle shooters aged between 22-28 years were selected as subjects. The index ofmuscular co-ordination was tested with three series. A steadiness tester was used with the diameters of 0.5, 0.31, 0.25, 0.18,0.15, 0.12, 0.10, 0.09, 0.07 inches and stylus of 0.062. Grip dynamometer was utilized for measuring local fatigue. Theresults indicated that 50% of rifle shooters were adversely affected by local fatigue of the arm, 80% of the subjects statedalteration in their muscular co-ordination after overall fatigue was induced. It was concluded that performance wassubstantially reduced when general fatigue was induced compared to local fatigue.

Switching to Aflibercept in Diabetic Macular Edema after Unsatisfactory Response to Other Anti-vascular Endothelial Growth Factor Drugs

PURPOSE: To evaluate the efficacy of switching to aflibercept in diabetic macular edema (DME) with suboptimal response to previous anti-vascular endothelial growth factor (anti-VEGF) injections. METHODS: A prospective interventional case series study recruited patients from a single center diagnosed with DME with suboptimal response to anti-VEGF injections. Three consecutive monthly injections of aflibercept were performed. The primary outcome measure was mean change in visual acuity after switching to aflibercept. RESULTS: Forty-two patients (42 eyes) were included. Baseline logarithm of the minimum angle of resolution (logMAR) visual acuity was 0.87 ± 0.23 and improved significantly to 0.62 ± 0.29, 0.56 ± 0.34, and 0.46 ± 0.35 at 1, 2, and 3 months, respectively, after the first injection. Mean baseline retinal thickness was 451.57 ± 107.09 µm and decreased significantly at 1, 2, and 3 months after switching to aflibercept (346.52 ± 79.03, 328.24 ± 81.98, and 313.71 ± 85.79 µm, respectively). Both visual improvement and mean change in retinal thickness were significant in patients with pre-aflibercept best-corrected visual acuity less than 1.0 logMAR but were not significant in patients with best-corrected visual acuity more than 1.0 logMAR. CONCLUSIONS: Switching to aflibercept in DME patients with an unsatisfactory response to previous anti-VEGF injections provided acceptable short-term visual and retinal architectural improvement.

Immunohistochemical Expression of Synaptophysin in the Adult and Developing Cervical and Lumbar Enlargements of the Spinal Cord of Rabbit

Background: The principle findings of synaptophysin immunoreactivity (SynpIR) during the ontogeny of rabbit spinal cord are: At E14, SynpIR precedes in the entire marginal layer especially at the entrance zone of dorsal root and motor neurite outgrowth emerged from the basal plate. At E21, SynpIR is expressed in the motoneurons of ventral and lateral horns of mantle layer growing into the ventrolateral columns of marginal layer. Methods: We found intensely stained thick tracts and diffuse axons among proliferating neuroblasts of mantle layer. The peripheral parts of ventral horns were occupied with closely packed multipolar neurons from which long dendrites departed toward the surface of marginal layer. Results: At E28, pronounced SynpIR presented in the ventral grey horn while the white matter was faintly stained., meanwhile the dorsal horn was more cellular than ventral and lateral horns. Few intensively SynpIR fibers cross the dorsal and ventral commissures. In adult, profuse SynpIR appeared in the entire grey matter, and stained dendrites departed from neurons in the lateral laminae into the adjacent funiculi as finger-like projections. These projections did not reach the surface, so that the outer one-third to onefourth of the funiculi contained little or no SynpIR. In the periphery of ventral horns, we found large multipolar neurons with faintly stained cytoplasm. The white matter and the neuroepithelial cells surrounding the central canal were almost unstained. Conclusion: Synaptophysinis a reliable marker for fiber outgrowth and synapse formation in therabbit spinal cord, and its differential expression levels is specific and almost completed before birth.

Nematicidal Compounds from the Leaves of Schinus terebinthifolius Against Root-knot Nematode, Meloidogyne incognita Infecting Tomato

The root-knot nematode, Meloidogyne incognita caused a serious damage to many plants. The phenolic components of the leaves of Schinus terebinthifolius were investigated as potential nematicidal agents for M. incognita. Nine compounds were isolated and characterized as viz., 1,2,3,4,6-pentagalloyl glucose (1), kaempferol-3-O-α-L-rhamnoside (Afzelin) (2), quercetin-3-O-α-L-rhamnoside (Quercetrin) (3), myricetin (4), myricetin-3-O-α-L-rhamnoside (Myricetrin) (5), methylgallate (6), protocatechuic acid (7), quercetin (8), and gallic acid (9) using nuclear magnetic resonance (NMR) spectroscopy. Compound 1 showed pronounced nematicidal activity compared to Oxamyl as a positive control. It showed the lowest eggs-hatchability (34%) and the highest mortality in nematode population (21% after 72 hours of treatment) at a concentration of 200 µg/mL. It exhibited the best suppressed total nematode population, root galling and number of eggmasses in infected tomato plants. The total carbohydrates and proteins were also significantly induced by 1 with reduction in total phenolics and increase in defense-related proteins. Thus, compound 1 could be a promising, more safe and effective natural nematicidal agent for the control of root-knot nematodes.

effect of saffron, basil, and red cabbage on rats with hepatic damage

This study was carried out to investigate the effect of saffron [Crocus sativus], basil [Ocimum sanctum], and red cabbage[ Brassica oleracea var. capitata f. rubra] on hepatic damage in rats. Seventy two adult male albino rats of Sprague-Dawley were divided into two main groups. The first main group [n=8] was kept as a negative control group [-ve].The rest of the animals [n=64] were subcutaneously injected with a single dose of CCL4 for the induction of necrosis. After injection of CCL4, rats were divided into 8 subgroups [n=8]. The first subgroup of rats continued as a positive control group [+ve]. the other subgroup were fed on the experimental diets containing different levels of saffron, basil, red cabbage and their mixtures. At the end of the experiment a period, liver enzymes such as ALT, AST, ALP, gamma glutamile transpeptidase [GGT], lactate dehydrogenase [LDH] were determined. Total protein, albumin, total and direct billirubin were determined. As well as histopathological examinations of organs [ liver and kidney]. Results indicated that feed intake was improved in all groups except group of rats fed on experimental diet containing 10% saffron. Body weight gain and feed efficiency ratio of ll groups were decreased when compared with negative control group moreover, liver enzymes ALT, AST, ALP in addition GGT, LDH, albumin, total and direct billirubin were decreased in the treated groups compared with positive control group. This study concluded that saffron, basil and red cabbage have a protective effect against hepatic damage in rats. This study recommends the inclusion of saffron, basil and red cabbage in the meals of patients with hepatic damage for possible beneficial effect

Relation of body mass index and waist circumference to some fertility markers among male partner of infertile couples

Background: Global estimates of infertility range between 8% and 12% of couples with women of childbearing age, affecting 50-80 million people. Excess weight is not only linked to increased risk of chronic disease but has also been shown to increase risk of reproductive problems. The consequences of obesity in female fertility have been widely studied, but studies in the male population are less frequent

Aim of the study: The aim of this study to clarify the role of body mass Index and waist circumference on some male-fertility laboratory markers among Egyptian males of infertile couples

Subjects and methods: A descriptive cross sectional study was carried out on a total sample of 59 males of infertile couples for at least one year after regular unprotected reproductive activity. BMI and WC were assessed, and a morning blood sample was taken assessing serum levels of testosterone, sex hormone-binding globulin, prolactin, luteinizing hormone [LH], follicle-stimulating hormone, and estradiol. Semen-analysis parameters were also measured

Results: In the present study, it was found that there was no statistical significant difference in relation of BMI or WC and sperm count. The likelihood of athenospermia was increased at higher BMI and WC values. BMI was not found to be associated with mean numeric values of the semen-analysis parameters, including sperm count, sperm morphology, and sperm motility. BMI was not significantly correlated with some hormone levels, such as LH and prolactin. However, a statistically significant inverse correlations was observed between WC and testosterone [r=-0.3 and p=0.04]. A different pattern of associations in this study was observed when the associations between BMI andWC and sexual hormone levels were compared between [fertile and subfertile] from infertile men

Conclusion: The association explored between WC and testosterone as well as different patterns of this association between [fertile and subfertile] from infertile men

Clonal diversity and antimicrobial resistance of Enterococcus faecalis isolated from endodontic infections

Background Enterococcus faecalis is considered to be one of most prevalent species in the oral cavity, particularly in endodontic infections. The aim of the present study was to investigate the prevalence of E. faecalis in dental root canals, clonal diversity by restriction fragment length polymorphism (RFLP) and randomly amplified polymorphic DNA (RAPD-PCR) analysis, and the antibiotic susceptibility of E. faecalis isolates. Results Among the bacterial strains isolated from dental root canal specimens (n = 82), E. faecalis was determined to have the highest prevalence followed by Streptococcus viridians, Leuconostoc mesenteroides, Staphylococcus aureus, Streptococcus mitis, and Pediococcus pentosaceus. Cluster analysis of RAPD-PCR and RFLP patterns of the E. faecalis isolates discriminated five and six different genotypes, respectively. Among the tested strains, 43%, 52% and 5% were susceptible, intermediate resistant, and resistant to erythromycin, respectively. In addition, one strain (E-12) was intermediate resistant to linezolid, and one isolate (E-16) was resistant to tetracycline. Interestingly, many of the intermediate resistant/resistant strains were grouped in clusters 5 and 6, according RAPD and to RFLP, respectively. Conclusions E. faecalis demonstrated the highest prevalence in the tested dental root canal specimens collected from Saudi patients and were grouped into five to six different genotypes. Different levels of antimicrobial susceptibility were observed in the tested E. faecalis strains, which clearly indicated that although bacterial strains may be similar, point mutations can result in extreme susceptibility or resistance to various antibiotics. This phenomenon is a cause for concern for clinicians in the treatment of dental infections caused by E. faecalis.

Detection of Diarrheagenic Escherichia coli in pet animals and its antibiotic resistance in Alexandria governorate

Benefits of having a dog or cat as a pet varies between owners according to the purpose, however, the limit between benefit and harm is sensitive because close contact between pets and humans may involuntarily represent harm for humans. Doga and cats have been proposed as possible reservoir of virulent Escherichia coli strains that may cause enteric and extra-intestinal infections in humans. In this study, we aimed to detect diarrheagenic Escherichia coli [DEC] in dogs and cats and their antibiotic resistant pattern[s]. Samples were collected from 70 dogs and cats from different veterinary clinics and hospitals in Alexandria. These animals suffered from diarrhea and other symptoms as fever, nausea, vomiting, chills, loss of appetite, muscle aches and bloating. Forty E. coli isolates were detected by culturing and biochemical tests, and were subjected to antimicrobial disc diffusion susceptibility test by using 10 different antibiotic discs, which are the most commonly used in pet animal clinics. Antibiotic resistance for individual antibiotics ranged from 5 to 98% with multiple resistances to 2 or more antibiotics detected in 15 [21%] samples. PCR for detection of virulent genes of E. coli; VT2e and eaeA genes as well as the antibiotic resistance blaTEM gene was performed. The VT2e and eaeA genes were found in E. coli isolates, from dogs and cats. These results collectively indicate that pet animals can harbor the Enteropathogenic [EPEC] and Enterotoxigenic Escherichia coli [ETEC] causing diarrhea at different ages with possible active transmission to contact human. Further, the high and multiple antibiotic resistance level can pose therapeutic challenges in contact humans. It is fundamental that veterinarians recommend preventive measures to pet owners towards the establishment of a long-term preventive programme against antibiotic resistant E. coli

Molecular study on foot and mouth disease virus in Beheira governorate, Egypt during 2014

Foot and mouth disease [FMD] is the most contagious disease of mammals and has a great potential for causing severe economic loss in susceptible cloven-hoofed animals. Egypt has a long history of occurrence of FMDV outbreaks, as the country is dependent on importion of live animals and meat from many countries all over the world. The present study was designed for detection, isolation and molecular characterization of FMDV circulationg among different regions in Beheira governorate. Thirty-eight tissue samples were collected from clinically diseased cattle and buffalo from different localities of Beheira governorate. Direct detection of FMDV using ELISA revealed that 84.2% of the samples were possitive. Molecular characterization showed that 24 samples [75%] were possitive for serotype O and eight samples [25%] were positive for serotype SAT2. This indicates the predominance of serotype O FMDV in Beheira, Egypt

Iron profile and dietary pattern of primary school obese Egyptian children

Poor iron status affects billions of people worldwide. The prevalence of obesity continues to rise in both the developed and developing nations. An association between iron status and obesity has been described in children and adults. The aim of the study was to assess the iron profile and dietary pattern in primary school-aged obese Egyptian children. A case-control study was conducted on 120 children, both obese [n=60] and control group [n=60], recruited from three primary governmental schools located in Dokki Sector, El-Giza Governorate, Egypt. Their ages ranged from 6 to 12 years. All children were subjected to full medical and dietetic history, anthropometric measurements, thorough clinical examination, and determination of complete blood count, serum iron, total iron-binding capacity, transferrin saturation [TS], and ferritin. Despite similar dietary iron intake in the two groups, obese children showed highly significantly decreased hematocrit, mean corpuscular volume, mean corpuscular hemoglobin, serum iron, and TS, and increased mean corpuscular hemoglobin concentration and total iron-binding capacity when compared with the nonobese group. The obese group showed a highly significant increased rate of iron deficiency [ID] [TS<15% or mean corpuscular volume<76 fl] when compared with the nonobese group. Obesity was a significant risk factor for the development of ID [odds ratio: 7.09, 95% confidence interval: 3.16-15.92]. The association between ID and obesity may have important public health and clinical implications. For primary school children with elevated BMIs, screening for ID should be considered. Increasing awareness of the importance of physical activity and carrying out nutritional education programs are required

level of bronchoalveolar lavage fluid prostaglandine E2; is it diagnostic of bronchogenic carcinoma?

Lung cancer is the leading cause of cancer-related mortality in the United States. Cigarette smoking is the number one risk factor for lung cancer. It causes about 90% of lung cancers [14]. Evaluation of bronchoalveolar lavage level of PGE2 in patients with primary bronchogenic carcinoma. The study was conducted on forty subjects; including twenty patients with bronchogenic carcinoma, ten patients with non-malignant lesions, and ten healthy control subjects. All subjects were submitted to fiberoptic bronchoscopy with bronchoalveolar lavage was done and examined for prostaglandin E2. The PGE2 level was significantly higher in BALF of group III [malignant group] compared to group I and II, with no significant difference between group I and group II. The cut- off value of PGE2 was 45.63 pg/ml with minimal overlap between malignant and benign lesions. Bronchoalveolar lavage level of PGE2 was significantly increased in patients with bronchogenic carcinoma

Non-Operative Treatment Versus Steroid Injections in the Management of Unicameral Bone Cysts

The cases of nine patients with unicameral bone cysts were reviewed from two orthopaedic centres. In one hospital, five patients received serial steroid injections, and at the other hospital four patients were treated conservatively following fractures. In the steroid injection group, three cases were in the proximal femur and two in the proximal humerus. The five steroid injection patients showed radiological evidence of cyst healing within six months of treatment. Subsequently four of the patients showed a satisfactory radiological outcome after a year and complete resolution after 2 years. In the conservative group, all four cases were in the proximal humerus. Persistent cystic lesions were observed in all four patients and two was complicated by another fracture within six months.

Etiology of pleural effusion among adults in the State of Qatar: a 1-year hospital-based study

There have been no systematic studies of diseases causing pleural effusion in Qatar. This prospective, hospital-based study involved all adult patients [> 15 years] with pleural effusions who were admitted to referral hospitals over a 1-year period. A total of 200 cases of pleural effusion were identified [152 males and 48 females]; mean age 45.1 [SD 18.5] years. A majority of patients [73.5%] were non-Qataris, mostly from the Asian subcontinent. The most frequent cause of pleural effusions was tuberculosis [32.5%], followed by pneumonia [19%], cancer [15.5%] and cardiac failure [13%]. The most frequent cause of malignant effusion was bronchogenic carcinoma [38.7%], whereas Gram-positive organisms were the most frequent isolates from empyema fluid [62.5%]. Histological examination and culture of pleural biopsy were the most useful diagnostic workup for tuberculosis effusions, whereas repeated cytological examination of pleural fluid and pleural biopsy were most useful for malignant effusions

Comparison of biostimulation and bioaugmentation for remediation of soil contaminated with spent motor oil

Aerobic fixed bed bioreactors were used to study and compare biostimulation and bioaugmentation for remediation of soil contaminated with spent motor oil. Bioaugmentation using consortium of bacteria and biostimulation using inorganic fertilizer and potassium dihydrogen orthophosphate were investigated. The bioremediation indicators used were the oil and grease content removals, total heterotrophic bacteria counts and carbon dioxide respiration rates. Results showed that biodegradations were very effective with 50, 66 and 75% oil and grease content removal efficiencies for control, bioaugmentation and biostimulation respectively after ten weeks. Carbon dioxide respiration followed similar pattern as the oil and grease content removals. Biostimulation option has the highest carbon dioxide generation [6 249 mg/kg] and the control with the least [4 276 mg/kg]. Therefore, the biostimulation option can be used to develop a realistic treatment technology for soils contaminated with spent motor oil

Activity patterns of residents in homes for the elderly in Alexandria, Egypt

To identify activity patterns of residents in homes for the elderly in Alexandria, we carried out a study on 188 elderly persons in 4 homes [2 governmental and 2 private]. Participants were interviewed individually using a structured interview schedule. Each home was visited daily for 1 week in order to assess the type of activities provided and the participation. Performance of activities was affected by health status, functional ability, lifestyle pattern [including individual practices and personal choices related to health and health risk] and type of home. Private homes, having more resources available, particularly financial resources, tended to involve their residents in physical and social activities more than governmental ones. The majority of the residents tended to be inactive

Cardiac events and cardiac T2[*] in Egyptian children and young adults with beta-thalassemia major taking deferoxamine

Cardiac events and death are not uncommon in adults with beta-thalassemia [beta-TM] taking deferoxamine [DFO] monotherapy because of poor compliance and possibly the less effectiveness of DFO in controlling cardiac iron overload. We sought to assess compliance with DFO, the percentage of shift to other iron chelators, and the occurrence of cardiac siderosis, and cardiac events and death in beta-TM patients on DFO monotherapy. Prospective, observational, 10-year follow-up of patients attending Ain Shams Thalassemia Unit, Cairo, Egypt. For all beta-TM patients aged 2-1 8 years attending the unit during January 1998 and taking DFO, we recorded all cardiac events [whether fatal or not] during January 2008. All patients still on DFO monotherapy and with a normal EKG and not showing symptoms or signs suggestive of heart failure [HF] were evaluated for cardiac siderosis byT2[*]. Of 412 patients, only 126 [31%] were still taking DFO monotherapy [only 43% of those were compliant], 136 were taking combined DFO and deferiprone [DFP], 72 were taking DFP and 32 were taking deferasirox [DFX]. Twenty-one were lost follow-up and 25 died [10 cardiac]. Eight of ten cardiac deaths and 12 of 15 non-cardiac deaths were in the DFO monotherapy group. Those taking DFO monotherapy with no HF and left ventricular ejection fraction [LVEF] by T2[*] >56% had a median age of 19 years and 56% were males; cardiac T2[*] was <20 ms in 30 [22%]; 10-20 ms in 20 [14.7%] and <10 ms in 10 [7.3%]. LVEF ranged from 58%-76% [median 64%]. Forty percent of T2* patients <10 ms were compliant with DFO. Fifty-eight percent of patients on DFO monotherapy were noncompliant, but even compliance did not prevent severe cardiac siderosis and most cardiac events [whether fatal or not] that occurred in the DFO monotherapy group
