Reduction of polycyclic aromatic hydrocarbons and nitrogen monooxide in combustion engine exhaust gases by clinoptilolite
The subject of this work was the investigation of zeolite as a sorbent of toxic gases. In Nizny Hrabovec in the Slovak republic, two layers of zeolite with the active component clinoptilolite can be found. The study presented here investigated the ability of this natural zeolite to reduce polycyclic aromatic hydrocarbons (PAH) and NO emissions from engine exhaust. Exhaust gases from combustion engines include toxic components such as carbon monoxide, nitrogen oxides and hydrocarbons. Polycyclic aromatic hydrocarbons (PAH) are a component of hydrocarbons causing harmful influence on life forms. The experiments focused on the potential reduction of these toxic gases based on the sorption and catalytic properties of natural zeolite. Also observed was the influence of chemical adjustment including incorporation of certain metal elements. Chemical analysis by mutually independent technologies served to observe the sorption of PAH with carcinogenic properties on the natural zeolite tested. The experiments showed that chemical modification improved the sorption and catalytic properties of natural zeolite. The PAH were analysed in an extract of the contaminated, thermally-activated natural zeolite and modified zeolite after washing with ammonium chloride, cobalt chloride and copper sulphate. The study also presents results of NO measurements obtained by testing the filter-sorptive automobile system.
Impact of model resolution on simulated wind, drifting snow and surface mass balance in Terre Adélie, East Antarctica

Published: July 2012

AbstractThis paper presents the impact of model resolution on the simulated wind speed, drifting snow climate and surface mass balance (SMB) of Terre Adélie and its surroundings, East Antarctica. We compare regional climate model simulations at 27 and 5.5 km resolution for the year 2009. The wind speed maxima in Terre Adélie and the narrow glacial valleys of Victoria Land are better represented at 5.5 km resolution, because the topography is better resolved. Drifting snow sublimation is >100 mm a-1 in regions with high wind speeds. Our results indicate a strong feedback between topography, wind gradients and drifting snow erosion. As a result, SMB shows much more local spatial variability at 5.5 km resolution that is controlled by drifting snow erosion, whereas the large-scale SMB gradient is largely determined by precipitation. Drifting snow processes lead to ablation in the narrow glacial valleys of Victoria Land. The integrated SMB equals 86 Gt. Although wind climate, drifting snow processes and SMB variability are better represented at 5.5 km, the area-integrated SMB is not significantly different between the simulations at 27 and 5.5 km. A horizontal resolution of 27 km is sufficient to realistically simulate ice-sheet wide SMB.
In Vitro Quantification of the Stiffening Effect of Corneal Cross-linking in the Human Cornea Using Radial Shearing Speckle Pattern Interferometry
Authors: Knox Cartwright Nathaniel E. , Tyrer John R. , Marshall John 
Published: July 2012

PURPOSE:
To quantify the magnitude of the stiffening effect of corneal cross-linking (CXL) by studying intact human corneas exposed to physiological pressure transients.

METHODS:

Nine organ-cultured human corneas mounted in artificial anterior chambers were studied. A radial shearing speckle pattern interferometer was used to measure changes in corneal strain following an increase in artificial anterior chamber pressure from 15.0 to 15.5 mmHg before and after treatment. Measurements were taken from all corneas with their epithelium intact before all underwent epithelial debridement. Three specimens were used as controls and did not receive any further treatment; three underwent riboflavin/ultraviolet A (UVA) CXL using 30 minutes of 370-nm irradiation at 3 mW/cm
2
following epithelial removal and saturation with 0.1% riboflavin; and three were fixed with the cross-linking agent 2.5% glutaraldehyde. Strain measurements were repeated after these treatments. Young’s moduli of individual corneas were calculated by mathematical analysis.

RESULTS:

Mean donor age was 81.7 years. Before treatment, the mean Young’s moduli of the control, riboflavin/UVA CXL, and glutaraldehyde-fixed corneas did not differ significantly: 0.46±0.03, 0.48±0.03, and 0.47±0.03 MPa, respectively. Following treatment these values changed to 0.46±0.2, 2.06±0.22, and 3.48±0.41 MPa, respectively. In proportional terms, this was equivalent to an increase in corneal Young’s modulus by a factor of 4.3 (
P
<.05) following riboflavin/UVA CXL and 7.3 (
P
<.05) after glutaraldehyde fixation.

CONCLUSIONS:
Riboflavin-UVA CXL increases the stiffness of organ-cultured corneas by a factor of more than four. This finding quantifies the efficacy of CXL in a physiologic configuration.

Authors: Santhiago Marcony R. , Smadja David , Zaleski Kelly , Espana Edgar M. , Armstrong Brian K. , Wilson Steven E. 
Published: July 2012

PURPOSE:
To analyze the results of LASIK retreatment performed by relifting the original femtosecond laser–created flap.

METHODS:
A retrospective analysis was performed on 1298 eyes from 688 patients treated with LASIK using the femtosecond laser to identify 88 consecutive eyes of 71 patients that underwent attempted flap lift to treat residual refractive error. The eyes were separated in groups in which the flap lift was possible or flap lift was not possible to investigate factors that could make flap lifting more difficult. The main factors evaluated were bed and side-cut energy and time between original surgery and retreatment. In addition, all retreated eyes were studied as a group to evaluate the refractive outcomes of flap lift retreatment.

RESULTS:

In 10 (11.3%) retreated eyes, flap lift was not possible without risk of flap injury due to strong healing of the original femtosecond laser interface. The group of eyes in which the flap could not be relifted had the attempted retreatment performed a longer time period after original LASIK (10.3±3.3 months) compared to the group in which the flap could be re-lifted (5.24±3.14 months) (
P
<.001). No significant differences were found between groups in any other parameters, including bed and side-cut energies. After retreatment, 82% of eyes achieved 20/20 or better uncorrected visual acuity.

CONCLUSIONS:
This study provides clinical evidence that flap lift retreatment after femtosecond laser–assisted LASIK achieves excellent clinical results and is significantly easier to perform in the first 6 to 8 months after primary LASIK.
Carabid beetle communities after 18 years of conservation tillage and crop rotation in a cool humid climate

Published: July 2012

AbstractAgricultural practices affect the biotic and abiotic conditions that determine food and shelter for carabid beetles (Coleoptera: Carabidae). We hypothesised that carabid communities would respond differently to 18 years of contrasted cropping practices in cereal-based rotations. We measured the effects of tillage (MP: moldboard plough; CP: chisel plough; NT: no-till) and previous crop sequence (cereal monoculture versus cereal–forage/cereal–oilseed rotation) on carabid beetle activity density, diversity, and community structure in corn (Zea maysLinnaeus, Poaceae) at La Pocatière, Québec, Canada. Carabid beetles were sampled monthly from May to September 2006, using pitfall traps. Although 19 carabid species were observed, assemblages were dominated byHarpalus rufipes(De Geer), particularly in the second half of the season. Multivariate analyses indicated a strong affinity of carabid species for the NT treatment throughout the season. Crop sequence and tillage had no effect on diversity (Shannon'sH′ ≤ 1.3) and evenness of carabid assemblage, but species richness and activity density were greater in NT than in tilled systems. Peak activity density of dominant species occurred at different times during the season, generally in accordance with preferred breeding season. Many species had greater activity density in NT than in tilled treatments. Because of their granivorous feeding habit, carabid populations such as that ofH. rufipescould be an important asset to NT, given the limited weed management options available for this system.

Published: July 2012

ABSTRACT

Aim and objective
This study was to find out optimal laparoscopic surgical procedures for fertility promotion and to compare its pregnancy outcome with in vitro fertilization (IVF) procedure.

Design and setting
Laparoscopic surgical procedures were performed under one consultant in a tertiary fertility set-up.

Materials and methods
Between January 1994 and December 2008, 3,982 cases of fertility promoting laparoscopic surgery (FPLS) were performed in our center. The procedures were related to uterus and appendages and especially endometriosis.

Results
The pregnancy rate following the surgical correction of minor tubal defects, ovarian cyst and uterine fibroids was between 25 and 30%, major tubal defects (5.7%) and severe endometriosis 18.5%. But the assisted reproductive technology (ART) outcome for the former was 30% and for the latter too, was between 25 and 30%.

Conclusion
Laparoscopic surgical corrections for minor tubal defects yield comparable results to ART, but for other two conditions, the latter is superior to the former.

Cervical Length Measurement by Transvaginal Ultrasound at 20 to 24 Weeks Gestation and the Timing and Mode of Delivery
Authors: Agarwal Shonali , Arora Payal , Maitra Nandita K 
Published: July 2012

ABSTRACT

Objective
To study the relationship between midtrimester cervical length measurement on transvaginal ultrasonography and timing and mode of delivery.

Materials and methods
A total of 200 asymptomatic antenatal women at 20 to 24 weeks gestation were recruited. Cervical assessment with transvaginal ultrasound was performed using a 5 MHz transvaginal probe. Findings of cervical assessment were then correlated with the timing and mode of delivery. Chisquare test and Odd's ratios with 95% confidence intervals were used.

Results
Sixteen percent women delivered preterm. A cervical length of ≤ 30 mm had good specificity and NPV. At the cut-off value of 25 mm or less, sensitivity was 31.3%, specificity was 100%, PPV was also 100% and NPV was 88.4%. Increased cervical length on TVS (>40 mm) was associated with higher rate of cesarean section as compared to <40 mm (66% vs 34%) and this observation was statistically significant.

Conclusion
Cervical length measured by TVS at midtrimester is a useful and significant predictor of the gestational age at delivery and the mode of delivery. The high negative predictive value avoids unnecessary interventions, such as tocolysis or cerclage in high-risk pregnancies.

Second Trimester Abortion with Vaginal Misoprostol: Is There Any Advantage with Prior Mifepristone Priming? A Comparative Study
Authors: Mukhopadhyay Partha , Bag Tara Sankar , Kyal Amit , Bhuniya Anup , Saha Tushar Kanti 
Published: July 2012

ABSTRACT

Objective
Second trimester medical termination of pregnancy (MTP) can be done by surgical or nonsurgical methods or by various combinations of the two. Every method has its advantages and disadvantages. An ideal method would be one which was safe, quick and 100% effective, inexpensive and without any immediate or late side-effects. However, in the absence of such, various methods in synergistic combinations have been tried to come close to an ideal method. The successes of medical method now appear to be useful in MTP even in second trimester of pregnancy. Our objective is to investigate the effectiveness of only vaginal misoprostol and compare with oral mifepristone plus vaginal misoprostol in second-trimester induction abortions (≥12 and ≤20 weeks).

Methods
The patients are selected after careful examination and necessary investigations were divided into group A (n = 62) which received 400 μg of vaginal misoprostol followed by 200 μg vaginal misoprostol 4 hourly till expulsion of fetus or a maximum dose of 2000 μg and group B (n = 60) which received 200 mg of oral mifepristone followed 48 hours later by vaginal misoprostol as in group A. Main outcomes measured were efficacy, blood loss, induction-abortion interval and complication.

Results
The present study showed that the both methods were effective in 2nd trimester MTP. Average blood loss was lesser in group B (131.66 ml) compared to group A (150 ml). Induction abortion interval was shorter in group B (6.62 hours) than in group A (12.19 hours). Ninty percent of group B and 80.7% of group A had no complications. Success rate was higher in group B.

Conclusion
Therefore, in our study, pretreatment mifepristone followed by misoprostol was found to be a very effective regimen for 2nd trimester abortion with lesser complications and higher efficacy.

Predictability of Fetal Birth Weight from Measurement of Fetal Thigh Circumference by Two-dimensional Ultrasound: A Prospective Study
Authors: Dasgupta Shyamal , Ghosh Tarun Kumar , Mukherjee Amitava , Sanyal Poushali , Karim Rezaul , Das Anita 
Published: July 2012

ABSTRACT

Objective
The aim of this study was to compare the predictability of the Vintzileos’ formula with the Hadlock's formula in estimating the fetal weight nearest to the actual birth weight.

Methods
It was a prospective observational study conducted with 138 antenatal mothers with single viable fetus and no major congenital abnormalities. A two-dimensional ultrasound scan was performed between 38 and 40 weeks gestation, which measured the biparietal diameter (BPD), head circumference (HC), abdominal circumference (AC), femur length (FL) and thigh circumference (TC) at the level of midthigh, and incorporated them to estimate fetal weight using the Hadlock's and the Vintzileos’ formulae.

Results
For the majority of the study population (63.04%), the mean fetal weight estimated by the Vintzileos’ formula was nearer to the mean actual birth weight compared to the Hadlock's formula. There was strong correlation (Karl Pearson's correlation coefficient r = 0.98, p-value <0.05) between the sonologically estimated and the neonatal thigh circumference.

Conclusion
The results of this study show that the fetal thigh circumference, if incorporated with other standard biometric parameters in estimating fetal weight by ultrasound, improves the predictability of birth weight estimation, and can predict intrauterine growth restriction.

Knowledge and Awareness about Preventive Health Seeking Behavior and Acceptability of Cervical Cancer Vaccine in Urban Women in Comparison with School Students
Authors: Divakar Hema 
Published: July 2012

ABSTRACT

Background
In India, cervical cancer is the single largest killer of middle-aged women, followed by breast cancer. Though the effective screening test is available, most of the women in developing and underdeveloped countries do not have access to Pap (papanicolou) smear screening due to poor literacy and low level of awareness both early detection and screening remain a major area of concern for health care persons.

Objective
To explore knowledge and awareness about preventive health seeking behavior and acceptability of cervical cancer vaccine in urban women in comparison with school students.

Materials and methods
This was a prospective study conducted to compare the awareness between 236 urban women attending the antenatal, gynaec and postdelivery outpatients and inpatients and 132 students aged between 12 to 14 years. A questionnaire was designed to tap the information about cervix-related questions, cancer cervix awareness and also about the Pap test and HPV vaccine.

Results
Overall 29.55% and urban women 19.07% did not know about the cervix. Overall, 79.55% students and 74.15% of urban women did not know about symptomatology of cervical cancer. Overall, 34.09% of students and 38.98% of women did not know about prevention of cervical cancer. Out of the total participants, 35.61% of students and 44.07% of women knew that death will happen, if cancer cervix was not treated or controlled for a long period.

Conclusion
Attempts to educate parents/peers and students themselves would intensify the awareness and improve the usage of the HPV vaccines in the desired cohort.

Regulation of Abnormal Atrioventricular Valve Development
Authors: Yalcin Huseyin C. , Ajaeb Sarah , Butcher Jonathan T. 
Published: July 2012

AbstractHemodynamic forces play an essential role in driving the morphogenesis of the embryonic heart and its valves. We previously found that genes that regulate heart morphogenesis like BMP2 and VEGFA, have hemodynamically specific patternings. However, how mechanical signals like wall shear stress (WSS) affect these expression levels to regulate heart morphogenesis is not fully understood. A detailed understanding of the hemodynamic environment and gene expression patterns inside normally and abnormally growing embryonic hearts would help inform the clinical progression of congenital heart defects and develop treatment strategies to restore these defects. We previously developed a system to quantify local fluid forces within growing embryonic heart where we combined imaging modalities with computational fluid dynamics (CFD), and quantified the hemodynamics within the AV canal and OFT in chicks. In the current study, we analyzed how altered hemodynamics drives changes in local gene expression and downstream morphogenesis of AV valves. Perturbed blood flow was created via either left atrial ligation (LAL) at HH24 or right atrial ligation (RAL) at HH25, to constrict blood flow on respective side of the heart. Hemodynamic environment in the AV canal for operated embryos were compared to control groups via doppler ultrasound at HH31. Gene expression levels were analyzed using RT-PCR. Heart morphology was analyzed at HH31 via micro-CT and histology. RT-PCR results at HH25 showed that LAL caused a drastic decrease in gene expression levels in LV myocardium (VEGFA expression 18.2±5.6%, BMP2 expression 21.7±1.4% compared to controls) and in AV cushions (VEGFA expression 9.8±8.1%, BMP2 expression 3.5±1.9 %), whereas in RV myocardium, expression levels were not affected significantly (VEGFA expression 77.5±5.8% , BMP2 expression 66.0±10.0%). Doppler ultrasound showed that neither peak blood velocities nor time averaged velocities in right and left AV canal are different for both LAL and RAL at HH31, suggesting WSS levels are not different between experimental groups (max shear stress 287dynes/cm2) at that stage. For LAL embryos, left AV valve area was smaller (48±4% vs. 67±6%, p<0.05, valve areas normalized to total left and right AV valve areas) and right valve area was bigger (52±4% vs. 33±6%, p<0.05) compared to controls, whereas in RAL embryos, opposite was true at HH31, right AV valve are was smaller (12±5 % vs. 33±6%, p<0.05) and left AV valve area was larger (88±5% vs %67±6, p<0.05). The ratio of right ventricle to left ventricle was significantly larger in LAL embryos compared to RAL embryos (1.1 vs 0.55). Our results show that morphological abnormalities follow the alterations in gene expression levels which are caused by changes in mechanical signals due to altered hemodynamics. We found that at later stages hemodynamics is restored to keep the blood circulation normal, with an altered morphology.
