Authors: Khan Tamkin , Rafique Muhammad , Zia Shumaila , Rizwan Aisha , Al-Shamrani Ali 
Published: March 2014

ABSTRACT

Objective
To study the incidence, causes and maternal outcome in emergency peripartum hysterectomy.

Materials and methods
Retrospective, descriptive study of emergency peripartum hysterectomy by analyzing the labor records of patients undergoing the procedure in the past 5 years.

Results
There were 57 emergency hysterectomies among the 28940 deliveries, over the past 5 years. The incidence of EPH was 1.97 per 1000 deliveries. The mean age of the patients was 35.03 ± 5.9 (range: 21-47) years. Mean parity was 4.8 ± 2.8 (range: 0-13). Of 57 patients, 50 (87.7%) patients had previous history of cesarean section (CS). The main indications for hysterectomy were placental abnormalities 63.1% (OR = 1.54; 95% CI = 9.5-13.34, p-value <0.001) and uterine atony 24.5% (OR = 1.42; 95% CI = 7.43-15.43, p-value <0.001). Subtotal hysterectomy was performed in majority 50 (87.7%) of the cases. Bladder injury was the significant intraoperative complication in 17 (30%) cases (OR = 1.87; 95% CI = 9.45- 18.97, p-value <0.001) with no residual damage. Infections were the commonest complication seen in 15 (26%) patients postoperatively. The maternal mortality occurred in 2 (3.5%) patients.

Conclusion
Emergency peripartum hysterectomy, though uncommon, remains a challenging but life saving procedure in obstetrics. Its indications in modern obstetrics are changing and still emerging. Abnormal placentation, previous CS, multiparity are important risk factors. Antenatal diagnosis of low lying and adherent placenta, minimizing the CS rate, proper and timely management of third stage of labor and emergency preparedness are imperative to minimize the chances of emergency peripartum hysterectomy and improving the outcome.

Authors: Soni Monica , Soni Prasoon , Agrawal Sudesh , Mehra Haritasha 
Published: March 2014

ABSTRACT

Objective
To analyze the cases of maternal mortality over a period of 3 years with regard to direct, indirect and associated causes and social correlates.

Materials and methods
Retrospective evaluation of the cases with respect to causes, admission to mortality interval, age, parity, antenatal booking, socioeconomic status, etc. and systemic analysis of all contributing factors.

Result and observation
A total of 66.67% of the deaths were due to direct causes with obstetric hemorrhage being the most common cause followed by puerperal sepsis. Anemia was the most important indirect cause followed by hepatitis and cardiovascular diseases.

Conclusion
A large number of maternal deaths seem to be avoidable if we are able to strengthen our maternity and child health services. Equally important, however, remains the upgradation of the status of females in the society with emphasis on literacy and general health awareness.

Management of Xerostomia Patient with Salivary Reservoir Designed in Upper Complete Denture and Lower Cast Partial Denture
Authors: Arora Vimal , Kumar Dinesh , Legha Virender Singh 
Published: April 2014

ABSTRACTXerostomia is a common complaint found often among older adults. Dry mouth has multiple oral health consequences and affects quality of life. It can produce serious negative effects on the patient's quality of life by affecting dietary habits, nutritional status, speech, taste and tolerance to dental prosthesis and increasing the risk of oral infection, including candidiasis and susceptibility to dental caries, periodontal disease and tooth loss. Saliva protects oral mucosa and teeth against harmful substances, lubricates the mouth to facilitate chewing, swallowing and speech, and reduces tissue trauma. Presence of adequate amounts of saliva within denture and tissue interface is essential. Without enough saliva, a denture will inadequately adhere to tissues, partly through loss of surface tension. Sometimes, the cause may easily be eliminated but, in many instances, it is not possible, and the condition is persistent and often progressive. There are several approaches to manage dry mouth. In this article, a palatal reservoir design for upper complete denture and lower cast RPD with salivary reservoir has been described, which completely satisfies the patient need for long time.How to cite this articleArora V, Kumar D, Legha VS, Kumar KV A.

ABSTRACT
This article considers how the recent digitization of witchcraft texts, which has provided unprecedented accessibility to archives and collections, offers scholars a unique perspective—unavailable though conventional interpretive approaches—to open new inroads into the spaces of early modern witchcraft, and enable new ways of reading and interpreting old witchcraft texts. It demonstrates how the Witches in Early Modern England project (WEME), led by Kirsten C. Uszkalo, designs and deploys strategically intersecting, innovative, and experimental digital tools to allow for robust searching and pattern finding within references from 290 texts, providing entries on approximately 150 years of English witchcraft published between 1550 and 1700. The article identifies some of the recurring patterns in the micro-histories of witchcraft in England as expressed in and discovered through WEME, and outlines the technologies that allow users to search a time line, map, search box, or filter in order to explore almost three thousand individual multidimensional nano-histories and align them, to create composites of the true and terrible stories of the early English witches. Moreover, the project's open-ended platform encourages further expansion by users, offering the opportunity to develop search tools that can enhance and inspire the academic interrogation of existing corpora.
New tools for extracting cork from Quercus suber L.: increasing productivity and reducing damage
Authors: Beira Davila Jesus , Prades Lopez Cristina , Santiago Beltran Ramon 
Published: March 2014

Aim of study: The aim of this study is to test new tools designed to debark cork oak trees: mechanized tools to perform cutting operations (IPLA-Morell, Stihl MC200 and COVELESS) and manual tools to separate and extract the cork (cork pincers, MIJURO).Area of study: Southwestern Spain.Material and methods: One of the longstanding problems affecting the sector is the shortage of skilled labor to perform debarking due to the difficulty of handling axes and the temporary nature of the work. To overcome these problems, four debarking systems using the new tools were designed according to the morphological properties of cork oak. The viability of the debarking systems were evaluated based on productivity (kg · person–1 · hour–1), production costs (€ · t1) and percentage of pieces smaller than 400 cm2 (%), and compared with the traditional system. Debarking quality and operator experience were also evaluated. A total of 204 trees were debarked.Main results: The new systems obtain better results: productivity is higher, the percentage of pieces is slightly lower and production costs are reduced, except for one system. Debarking quality improves with the new tools as cork is extracted in a more precise and cleaner manner, thus permitting cork manufacturers to obtain higher yields from the cork planks.Research highlights: Semi-skilled operators using the new tools obtain very similar results to skilled operators using axes. This would therefore resolve the problem of the lack of skilled labor, while improving the working conditions of operators. The results demonstrate that the new tools are viable for cork debarking and can bring potential benefits to the sector.Key words: Q. suber L.; cork debarking; mechanization; productivity; cork stripping damage; axe; IPLA_Morell, Sthil MC 200, COVELESS.

Published: April 2014

Abstract
A single-laboratory validation (SLV) for the analysis of vitamin D3 was performed in four types of dietary supplements (capsules, soft gels, syrups, and tablets) using LC-MS/MS. Samples were treated by alkaline saponification for oil-based soft gels and utilized EDTA solution for capsules, syrups,and tablets prior to n-hexane extraction. Vitamin D3 in sample extracts was separated on a reversed-phase C18 column (100 × 2.1 mm, 2.7 μm) using a mobile phase of a 95 + 5 (v/v) mixture of 5 mM ammonium formate in methanol containing 0.1% formic acid and 5 mM ammonium formate in 0.1% formic acid running at a flow rate of 0.2 mL/min. Vitamin D3 was confirmed by the presence of three fragment ions at m/z 107, 159, and 259 within a defined retention time window from the precursor ion at m/z 385. Quantitation was based on the peak area at m/z 367 to that of the internal standard (d3-vitamin D3) at m/z 370 with reference to the respective response ratios of the calibration standards. The linear response of vitamin D3 ranged from 0.10 to 6.29 mg/L and the correlation coefficient (r) of the six-point calibrationcurves was &gt;0.999. Accuracy, in terms of the spiked recoveries from blank syrup and starch powder at three different concentration levels, was 101–103%. Precision, determined by two different analysts over a period of 5 weeks, ranged from 2.7 to 7.0%for the four preparations. The SLV demonstrates the present LC-MS/MS method is reliable and robust for the determination of vitamin D3 in the studied dietary supplements. Considering the attainmentof satisfactory SLV results, further validation through intra-laboratory collaborative study is recommended.

Published: April 2014

Abstract
A new ELISA kit to quantitate the level of paralytic shellfish poisoning (PSP) toxins in crude shellfish extracts was developed. A conjugate for preparing antigen and a novel antibody used in the ELISA wasprepared based on the unique reactions between C11-O-sulfate toxins such as gonyautoxins 2 and 3 (GTX2,3) and various thiol compounds, followed by coupling to keyhole limpet hemocyanin. The compounds necessary for competitive ELISA, labeled toxin and an artificial standard toxin to replace saxitoxin in the analysis, were also produced by the same techniques. Theresulting ELISA recognized all the toxin components tested; however, carbamoyl-N-sulfate derivatives such as B and C toxins and N1-OH toxins such as neoSTX and GTX1,4 showed low affinity to the antibody. The difference in the reactivity of the antibody observed among the toxin components prevents accurate quantification of the toxin amounts in shellfish extracts. To address this problem, the former toxin components were transformed to corresponding carbamate toxins by mild HCl treatment according to a conventional method. The reduction of N1-OH of the latter toxins to N1-H was performed by our original method using hemin as a catalyst. We report here the new ELISA kitcoupled with the pretreatment process to transform the toxin components favorable for the quantitative analysis of PSP toxins.

Published: March 2014

AbstractMercury (Hg) is a toxic metal that is transported globally through the atmosphere. Emissions of Hg from mineral reservoirs and recycling between soil/biomass, oceans, and the atmosphere are fundamental to the global Hg cycle, yet past emissions from anthropogenic and natural sources are not fully constrained. We use a sediment core from Yanacocha, a headwater lake in southeastern Peru, to study the anthropogenic and natural controls on atmospheric Hg deposition during the Holocene. From 12.3 to 3.5 ka, Hg fluxes in the record are relatively constant (mean ± 1σ: 1.4 ± 0.6 µg m−2 a−1). Past Hg deposition does not correlate with changes in regional temperature and precipitation or with most large volcanic events that occurred regionally (~300–400 km from Yanacocha) and globally. In 1450 B.C. (3.4 ka), Hg fluxes abruptly increased and reached the Holocene‐maximum flux (6.7 µg m−2 a−1) in 1200 B.C., concurrent with a ~100 year peak in Fe and chalcophile metals (As, Ag, Tl) and the presence of framboidal pyrite. Continuously elevated Hg fluxes from 1200 to 500 B.C. suggest a protracted mining‐dust source near Yanacocha that is identical in timing to documented pre‐Incan cinnabar mining in central Peru. During Incan and Colonial time (A.D. 1450–1650), Hg deposition remains elevated relative to background levels but lower relative to other Hg records from sediment cores in central Peru, indicating a limited spatial extent of preindustrial Hg emissions. Hg fluxes from A.D. 1980 to 2011 (4.0 ± 1.0 µg m−2 a−1) are 3.0 ± 1.5 times greater than preanthropogenic fluxes.

AbstractAs part of TIGERZ campaign, latitudinal variation of aerosol optical properties was analyzed over Indo‐Gangetic Plains (IGP) to central Himalayas during premonsoon of 2008 and 2009. Measurements of aerosol optical depth (AOD) were performed using Aerosol Robotic Network Sun photometer at four sites with different aerosol environments. The AOD increases from Nainital located in central Himalayas to Kanpur located in IGP region. Further, aerosol size varies spatially with dominance of coarse‐mode aerosols at Kanpur compared to fine‐mode aerosols dominated at Nainital. Spectral variation of single‐scattering albedo suggests that during premonsoon, dust is the dominant species in the IGP with exception of Pantnagar, where absorbing aerosols are dominant. The optical properties of aerosols are calculated, and shortwave clear‐sky aerosol radiative forcing (ARF) is estimated. An insignificant difference is found in columnar ARF and columnar heating rate (HR) when vertical profiles of aerosols are included in radiative transfer models. Over Nainital, average ARF is estimated to be −7.61, −45.75, and 38.14 W m−2 at top of atmosphere (TOA), surface (SUR), and in the atmosphere (ATM), respectively. Average ARF is less negative at Kanpur compared to Pantnagar and Bareilly with values −17.63, −73.06, and 55.43 W m−2 at TOA, SUR, and ATM, respectively. ARF shows positive gradient from the highlands to the IGP sites; larger TOA and SUR cooling were observed at the three sites compared to the highland site. This translates into large columnar HR with estimated average values as 1.07, 1.41, 1.58, and 1.56 K d−1 for Nainital, Pantnagar, Bareilly, and Kanpur, respectively.

Published: March 2014

ObjectiveProteolytic cleavage of the amyloid precursor protein (APP) generates β‐amyloid (Aβ) peptides. Prolonged accumulation of Aβ in the brain underlies the pathogenesis of Alzheimer disease (AD) and is regarded as a principal target for development of disease‐modifying therapeutics.MethodsUsing Chinese hamster ovary (CHO) APP751SW cells, we identified and characterized effects of 2‐([pyridine‐2‐ylmethyl]‐amino)‐phenol (2‐PMAP) on APP steady‐state level and Aβ production. Outcomes of 2‐PMAP treatment on Aβ accumulation and associated memory deficit were studied in APPSW/PS1dE9 AD transgenic model mice.ResultsIn CHO APP751SW cells, 2‐PMAP lowered the steady‐state APP level and inhibited Aβx‐40 and Aβx‐42 production in a dose–response manner with a minimum effective concentration ≤ 0.5μM. The inhibitory effect of 2‐PMAP on translational efficiency of APP mRNA into protein was directly confirmed using a 35S‐methionine/cysteine metabolic labeling technique, whereas APP mRNA level remained unaltered. Administration of 2‐PMAP to APPSW/PS1dE9 mice reduced brain levels of full‐length APP and its C‐terminal fragments and lowered levels of soluble Aβx‐40 and Aβx‐42. Four‐month chronic treatment of APPSW/PS1dE9 mice revealed no observable toxicity and improved animals' memory performance. 2‐PMAP treatment also caused significant reduction in brain Aβ deposition determined by both unbiased quantification of Aβ plaque load and biochemical analysis of formic acid–extracted Aβx‐40 and Aβx‐42 levels and the level of oligomeric Aβ.InterpretationWe demonstrate the potential of modulating APP steady‐state expression level as a safe and effective approach for reducing Aβ deposition in AD transgenic model mice.

Wealth in old Hawai‘i: good‐year economics and the rise of pristine states
Authors: Dye Thomas S. 
Published: March 2014

AbstractThe journals of Captain Cook and his crew contradict bad‐year economic theories that posit that traditional Hawaiian farmers were living at the margin. Recognising that pig herds were wealth‐assets in old Hawai‘i, an alternative good‐year economic theory is developed that interprets the introduction of sweet potato and the development of the rain‐fed agricultural systems in which it was cultivated as processes in the creation and management of wealth. The wealth produced in this way was probably used, in part, to promote marriage alliances among elite families. According to the good‐year economic theory, fluctuations in the products of the rain‐fed agricultural facilities introduced variability into the supply of wealth‐assets, which complicated the maintenance of alliances and were one cause of the wars that played a crucial role in the emergence of primary states in traditional Hawai‘i.

Published: March 2014

AbstractThis paper investigates the output feedback stabilization of stochastic nonholonomic systems which have both nonlinear drifts and Markovian switching. The state‐scaling and backstepping techniques are exploited in the design of control laws. The output feedback stabilizing control laws and switching control strategy are proposed so that the closed‐loop system can be stabilized in probability in the large. In the end, an example of nonholonomic mobile robots is provided to illustrate the effectiveness of control laws.
Revisiting the TP Model Transformation: Interpolation and Rule Reduction
Authors: da Silva Campos Víctor Costa , Tôrres Leonardo Antônio Borges , Palhares Reinaldo Martinez 
Published: March 2014

AbstractThe tensor‐product (TP) model transformation is a numerical technique that finds a convex representation, akin to a Takagi‐Sugeno (TS) fuzzy model, from a given linear parameter varying (LPV) model of a system. It samples the LPV model over a limited domain, which allows the use of the higher order singular value decomposition (HOSVD) and convex transformations that leads to the TS representation of the LPV model. In this paper, we discuss different strategies that could be used on the sampling step of the TP model transformation (which in turn lead to different membership function properties of a TS fuzzy model). Additionally, this paper discusses how the other steps could be used to reduce the number of rules of a given TS fuzzy model. In cases where nonzero singular values were discarded in the rule reduction, we also show how to obtain an uncertain model that covers the original.
