Large adnexal mass: is laparoscopic surgery a safe option?
No full textBackground: Laparoscopic surgery is regarded as the gold standard for management of adnexal tumours due to many advantages. Currently, the exact size of the adnexal tumour contraindicating laparoscopic management has not been clearly defined. Some studies suggest laparotomy for the treatment of adnexal tumours larger than 8 to 10 cm. Risk of malignancy increases with large cysts. Issues with operation of huge adnexal masses are limited surgical field, difficulty in inserting trocars and removing the specimen without rupture. This study aims to evaluate the feasibility and surgical outcomes of laparoscopic surgery for large adnexal masses.Methods: A prospective observational study was conducted in the Department of Obstetrics and Gynaecology, JSS Medical College, Mysuru.Results: 35 patients with large adnexal masses, which were thought to be benign, were subjected to laparoscopic surgery. Mean diameter of masses as per the pre-operative ultrasound measurements was 12.2cm (range: 10.1-20.4cm). The mean operative time was 51.15minutes, estimated blood loss was 85.4ml, duration of postoperative hospital stay was 2.8 days. Serous cystadenoma was the most common histopathological finding. However, one case of borderline tumour was found.Conclusions: The potential risk of malignancy is the most important limiting factor for laparoscopic management of large ovarian cysts. Therefore, it is necessary to establish risk profiles of patients with adnexal masses in order to benefit from minimally invasive surgery wherever possible. The current study supports laparoscopic management of large ovarian cysts as a technically feasible method if proper case selection is made
LDH as a prognostic marker in hypertensive pregnancy
No full textBackground: Pregnancy induced hypertension (PIH) is a global problem with a 5-15% incidence rate in India and complicating 10-17% of all pregnancies. These are multisystem disorders and lead to a lot of cellular death. LDH is an intracellular enzyme and its level is increased in these women due to cellular death. So, serum LDH levels can be used to assess the extent of cellular death and thereby the severity of disease in this group of women. The objective of the study was to correlate the severity of the disease, maternal and perinatal outcome with Lactic Dehydrogenase (LDH) levels in serum in patients of preeclampsia and eclampsia.Methods: A prospective comparative study was conducted in the department of Obstetrics and Gynecology, JSS Medical Hospital, Mysore.Results: LDH levels were significantly elevated in women with preeclampsia and eclampsia (<0.001). Higher LDH levels had significant correlation with high blood pressure (P <0.10) as well as poor maternal and perinatal outcome.Conclusions: High serum LDH levels correlate well with the severity of the disease and poor outcomes in patients of preeclampsia and eclampsia.</jats:p
Role of bicarbonate as a pH buffer and electron sink in microbial dechlorination of chloroethenes
No full textAbstract Background Buffering to achieve pH control is crucial for successful trichloroethene (TCE) anaerobic bioremediation. Bicarbonate (HCO3−) is the natural buffer in groundwater and the buffer of choice in the laboratory and at contaminated sites undergoing biological treatment with organohalide respiring microorganisms. However, HCO3− also serves as the electron acceptor for hydrogenotrophic methanogens and hydrogenotrophic homoacetogens, two microbial groups competing with organohalide respirers for hydrogen (H2). We studied the effect of HCO3− as a buffering agent and the effect of HCO3−-consuming reactions in a range of concentrations (2.5-30 mM) with an initial pH of 7.5 in H2-fed TCE reductively dechlorinating communities containing Dehalococcoides, hydrogenotrophic methanogens, and hydrogenotrophic homoacetogens. Results Rate differences in TCE dechlorination were observed as a result of added varying HCO3− concentrations due to H2-fed electrons channeled towards methanogenesis and homoacetogenesis and pH increases (up to 8.7) from biological HCO3− consumption. Significantly faster dechlorination rates were noted at all HCO3− concentrations tested when the pH buffering was improved by providing 4-(2-hydroxyethyl)-1-piperazineethanesulfonic acid (HEPES) as an additional buffer. Electron balances and quantitative PCR revealed that methanogenesis was the main electron sink when the initial HCO3− concentrations were 2.5 and 5 mM, while homoacetogenesis was the dominant process and sink when 10 and 30 mM HCO3− were provided initially. Conclusions Our study reveals that HCO3− is an important variable for bioremediation of chloroethenes as it has a prominent role as an electron acceptor for methanogenesis and homoacetogenesis. It also illustrates the changes in rates and extent of reductive dechlorination resulting from the combined effect of electron donor competition stimulated by HCO3− and the changes in pH exerted by methanogens and homoacetogens.</p

Mixed germ cell tumour complicated by pulmonary thromboembolism: a case report
No full textMalignant ovarian germ cell tumours (MOGCTs) are a heterogeneous group of tumours that have several histological different types derived from primordial germ cells of the embryonic gonad. They account for less than 5% of all ovarian malignancies, and are seen in the second and third decade of life. The majority of germ cell tumours are diagnosed in the early stages. Histology, FIGO stage and residual tumour after surgery are the most important prognostic factors. Recent multimodality therapy with staging laparotomy and conservative surgery, followed by platinum based chemotherapy, is associated with survival rates of 60 - 80%, even in patients with advanced disease. Mixed germ cell tumours are extremely rare and the prognosis depends on the size of each component of the tumour. The exact incidence of thrombo embolic events in patients with malignancy is difficult to determine. However ovarian malignancy is strongly associated with venous thrombo embolism. We report a case of a fourteen year old girl with a mixed GCT, with elements of yolk sac tumour and embryonal carcinoma, who succumbed to pulmonary thromboembolism
The potential impact of Autonomous vehicles on the labor market in The Netherlands
No full textThe automobile industry has been continuously working on bringing automation in motor vehicles for the betterment of human life. Advancement in technology has helped companies manufacture cars that can drive and navigate on their own called Autonomous vehicles (AVs). There are numerous effects of AVs on society. The AVs are forecast to bring enormous changes in the labor market. The objective of the study is to understand how the introduction of AVs will impact the labor market related to skills and job types in The Netherlands. There has been a fear that changes in geography and technological change threatens the employee’s mismatch with their skill and job. Over multiple decades this mismatch has increased the demand for new skills and the supply is maintained by increasing the education level of workers. This demand for skill is due to technological change and it is predicted that there will be similar changes due to the introduction of AVs. To achieve the objective of this research, 13 semi-structured interviews were conducted with the academicians from the universities of The Netherlands and experts from labor organizations of The Netherlands. Interview questions were generated with the help of the conceptual model which was generated by the literature. From the result of the interview, it can be concluded that the AVs will not be having a major impact on the labor market and the problem will be very minimal related to skill and job types. Skill mismatch is not a major concern in The Netherlands and it will be only persisting for a short duration. There will be an increase in jobs and skills related to ICT and the supervision of AVs. Furthermore, interviewees claimed that the skill mismatch problem will not emerge if the introduction of AVs to the society is done incrementally and gradually. Based on the result, it is recommended for the future study should focus on quantifying the impact of AVs on the labor market based on the wage effect and inequality. And also expand the study in other countries if the effect is different compared to The Netherlands.Management of Technology (MoT
Improving lipid recovery from Scenedesmus wet biomass by surfactant-assisted disruption
No full textabstract: Microalgae-derived lipids are good sources of biofuel, but extracting them involves high cost, energy
expenditure, and environmental risk. Surfactant treatment to disrupt Scenedesmus biomass was evaluated
as a means to make solvent extraction more efficient. Surfactant treatment increased the recovery of fatty
acid methyl ester (FAME) by as much as 16-fold vs. untreated biomass using isopropanol extraction, and
nearly 100% FAME recovery was possible without any Folch solvent, which is toxic and expensive. Surfactant
treatment caused cell disruption and morphological changes to the cell membrane, as documented by
transmission electron microscopy and flow cytometry. Surfactant treatment made it possible to extract wet
biomass at room temperature, which avoids the expense and energy cost associated with heating
and drying of biomass during the extraction process. The best FAME recovery was obtained from highlipid
biomass treated with Myristyltrimethylammonium bromide (MTAB)- and 3-(decyldimethylammonio)-
propanesulfonate inner salt (3_DAPS)-surfactants using a mixed solvent (hexane : isopropanol = 1 : 1, v/v)
vortexed for just 1 min; this was as much as 160-fold higher than untreated biomass. The critical micelle
concentration of the surfactants played a major role in dictating extraction performance, but the growth
stage of the biomass had an even larger impact on how well the surfactants disrupted the cells and
improved lipid extraction. Surfactant treatment had minimal impact on extracted-FAME profiles and,
consequently, fuel-feedstock quality. This work shows that surfactant treatment is a promising strategy for
more efficient, sustainable, and economical extraction of fuel feedstock from microalgae.The supporting information contains 6 pages, including Table S1 for the character of different growth type of biomass, Fig S1 for the quantity of FAME under the two
different solvents, Fig S2 FAME profile via Folch and isopropanol extraction under different surfactant treatments, Fig S3 Cell structures of protein-rich Scenedesmus biomass under 3_DAPS, MTMA and SDS treatments, Fig S4 Cell structures of intermediate-lipid Scenedesmus biomass under 3_DAPS, MTMA and SDS treatments, and Fig S5 for the flow cytometer assay with SYTOX green emission.View the article on the journal page at http://pubs.rsc.org/en/content/articlelanding/2015/gc/c5gc02159
Effects of pulsed electric field treatment on enhancing lipid recovery from the microalga, Scenedesmus
No full textabstract: Chloroform and methanol are superior solvents for lipid extraction from photosynthetic microorganisms, because they can overcome the resistance offered by the cell walls and membranes, but they are too toxic and expensive to use for large-scale fuel production. Biomass from the photosynthetic microalga Scenedesmus, subjected to a commercially available pre-treatment technology called Focused-Pulsed® (FP), yielded 3.1-fold more crude lipid and fatty acid methyl ester (FAME) after extraction with a range of solvents. FP treatment increased the FAME-to-crude-lipid ratio for all solvents, which means that the extraction of non-lipid materials was minimized, while the FAME profile itself was unchanged compared to the control. FP treatment also made it possible to use only a small proportion of chloroform and methanol, along with isopropanol, to obtain equivalent yields of lipid and FAME as with 100% chloroform plus methanol.NOTICE: this is the author's version of a work that was accepted for publication in BIORESOURCE TECHNOLOGY.
