The End of an Era?
Authors: Lewis Jeremy
Published: March 2018

In 1972, American orthopaedic surgeon Charles Neer published his seminal paper, “Anterior Acromioplasty for the Chronic Impingement Syndrome in the Shoulder: A Preliminary Report.” It wasn't a robust scientific paper; however, it changed the direction of orthopaedic practice for the next half century. Neer argued that a primary cause of shoulder pain was attrition of the supraspinatus tendon and related structures from the overlying acromion, especially when the arm was elevated. Neer recommended surgical removal to stop the impingement, and over the last half century, it could be argued that millions of people around the globe would have undergone acromioplasty surgery to stop this portion of the bone impinging onto the soft tissues located in the subacromial space. More recently, against the tide of subacromial decompression surgery there has been dissent, and the relationship between the acromion and symptoms has been challenged.

Screening and Isolation of Lipase Producing Fungi from Marine Water Obtained from Machilipatnam Costal Region
Authors: Lanka Suseela , B. Tabitha Trinkle
Published: March 2018

The marine environment is highly susceptible to pollution by oil spillages and hence become an importance source for
screening potential lipolytic microorganisms capable of degrading hydrocarbons. In addition to their salt tolerance,
enzymes from halophiles can withstand and carry out reactions very much efficiently under extreme operational conditions
encountered in industrial processes. In the present investigation, an extracellular lipase producing fungal organisms were
screened and isolated from marine water samples collected from Manginapudi beach at Machilipatnam, Krishna district,
A.P. India. Among 15 species of fungi isolated, 5 dominant fungi were selected to study their lipase producing activity.
The extracellular lipase secreted in to the minimal salt broth was assayed both by qualitative screening method such as
phenol red agar plate method and quantitative titrimetric method. Of the 5 dominant fungal isolates, Engyodontium sp. was
found to produce maximum lipase, 7.2 U/mL compared to other fungal members. Since there is growing demand for
lipases, rapid and persistent screening for microorganisms will open new insights for novel enzymes to be used for various
synthetic processes and as well provides faster ways to solve many environmental problems. The present study gains its
importance in view of this.

Evaluation of Antioxidant Status in Cold Brewed Tea with Respect to Hot Decoction: Comparative Study Between Green and Black Varieties
Authors: Das Chandrima , Chatterjee Sirshendu
Published: March 2018

Tea is known as nature low calorie wonder drink. Consumption of hot tea decoction became popular from the ancient
times. Currently researchers observed that many secondary metabolites that are heat sensitive might get destroyed on
heating. Moreover people, who are permanently live at higher altitude or the members of high altitude expedition team, are
deprived of various tea brewing facilities like electricity, fuel etc and hence they have to depend on brewing tea at cold
condition only for consumption. In this backdrop present study aims at analysis of antioxidants like polyphenols, flavonoids
and free radical scavenging activity of cold brewed tea and compared with its hot decoction. The study highlighted that
cold brewed green tea harbour more polyphenolics and flavonoids with respect to its hot decoction. However no significant
change being observed between hot and cold decoction of black tea. It is also observed that mg Ascorbic Acid Equivalent
per cup of cold and hot tea brew has no significant difference and hence both the brews can be consumed for replenishment
of antioxidant requirements

Phenotypic and Genotypic Characterization of Serratia marcescens
from Clinical and Environmental Sources
Authors: N. Gayathri , Subashkumar R.
Published: March 2018

S.marcescens is opportunistic pathogens that cause nosocomical infections. There have been many reports concerning
the identification, antibiotic susceptibility, pathogenicity, epidemiological investigations and typing of this organism.
Accurate identification is important in defining outbreaks. In the present study, S. marcescens have been selected from
the natural sources and were then confirmed with 16S rRNA identification method with cultures of MTCC. To
investigate these S. marcescens isolates, random amplification of polymorphic DNA (RAPD) was used in conjunction
with the specific primers. The RAPD patterns for each isolate were identified on the basis of identical numbers and sizes
of the bands. And by using dendrogram we can able to show, that the pattern of the primers to separate isolates was
closely related to their sequence homology with the genome and their amount of guanine and cytosine nucleotide content.
S. marcescens as a pathogen shows a tissue-damaging capacity. The cytotoxic activity is mainly elicited by the secreted
hemolysin/cytotoxin ShlA. Here, the isolates were tested for hemolytic activity. S. marcescens is known to be frequently
resistant to various antibiotics and our results also showed such a tendency.

Published: March 2018

The spectrum of antibacterial activities shown by fatty acid fractions of different microalgae, depending on the
unsaturation pattern and chain length are still need to be explored. This study provides information on the fatty acid
composition of three microalgae, Chlorella marina, Nannochloropsis occulata and Chaetoceros affinis along with their
antibacterial activities against selected clinical and fish pathogens. PUFA content of fatty acid fractions followed the
order N. occulata > C. affinis > C. marina. Greater abundance of eicosapentanoic acid found in Nannochloropsis
occulata (27.39 ± 0.15%) and Chaetoceros affinis (25.34 ± 0.23%) might be responsible for higher bacterial inhibition
shown by these fractions.
Potentials of Some Nigerian Herbs and Spice as Source of Pharmaceutical Raw Materials: Opportunity for Global Market Competitiveness
Authors: O. Egharevba H. , S. Gamaniel K.
Published: March 2018

Food has been seen and known to be the very basis of human health and wellbeing since time immemorial. Also, ancient
history and tradition, has helped to emphasize the benefits of herbs and spices in traditional medicine. Advancement in
biomedical technology has led to the duty in science to study and review the interface between foods and medicines,
particularly those derived from medicinal plants. Scientific supports for the health benefits of medicinal plants particularly
herbs and spices, have led to increased consumer demands for some herbs and spices creating huge international demands
and market. However, despite the huge resources of these raw materials in Nigeria and Africa, they remain an almost
insignificant player in the global spice market. The interface between Nigerian plant products and resources used as food,
herbs and spices on one hand and their potential for development as a competitive source of pharmaceutical raw material
for nutraceutical industry and the global market of herb and spices on other hand, is discussed.

Challenges in Creating Online Exercises and Exams in Organic Chemistry
Authors: Jaun Bernhard , Thilgen Carlo
Published: March 2018

e-Learning has become increasingly important in chemical education and online exams can be an attractive alternative to traditional exams written on paper, particularly in classes with a large number of students. Ten years ago, we began to set up an e-course complementing our lecture
courses Organic Chemistry I and II within the open-source e-learning environment Moodle. In this article, we retrace a number of decisions we took over time, thereby illustrating the challenges one faces when creating online exercises and exams in (organic) chemistry.
Special emphasis is put on the development of MOSFECCS (MOlecular Structural Formula Editor and Calculator of Canonical SMILES), our new editor for drawing structural formulae and converting them to alphanumeric SMILES codes that can be submitted as answers to e-problems. Convinced that the
possibility for structure input is essential to set up sensible chemistry quizzes and exams, and realising that existing tools present major flaws in an educational context, we decided to embark on the implementation of MOSFECCS which takes into account a number of didactic aspects.

Authors: Müller Markus T.
Published: March 2018

The Chemistry Cube Game invites students at secondary school level 1 and 2 to explore basic concepts of chemistry in a playful way, either as individuals or in teams. It consists of 15 different cubes, 9 cubes for different acids, their corresponding bases and precursors, and 6 cubes
for different reducing and oxidising agents. The cubes can be rotated in those directions indicated. Each 'allowed' vertical or horizontal rotation of 90° stands for a chemical reaction or a physical transition. Two different games and playing modes are presented here: First, redox chemistry
is introduced for the formation of salts from elementary metals and non-metals. Second, the speciation of acids and bases at different pH-values is shown. The cubes can be also used for games about environmental chemistry such as the carbon and sulphur cycle, covering the topic of acid rain,
or the nitrogen cycle including ammoniac synthesis, nitrification and de-nitrification.

The accuracy of nozzle design can be improved by validation. Two methods of validation is software or hardware application. The software can be either CFD software or special software for the nozzle design, such as NOZZLE ® or Aerospike ®. The limitations of CFD software is on unsteady flow conditions. while the limitations of special software is the obscurity of assumptions used. Therefore, the flow validation experimental is important to be implemented. Lapan has three units of wind tunnels, namely subsonic, transonic and supersonic. They have the capability to measure the external flow of the body. While the nozzle design purpose is mostly to investigate the internal flow of the nozzle. Therefore, the nozzle flow testing system which is called a mini wind tunnel has been designed.This wind tunnel is designed to have speed of Mach 2.4, but the effective speed of 2 Mach. By using a calculation we obtain the run time of 46 seconds. If we assume the pressure drop is 40%, then actually the run time is 28 seconds.Keyword:Windtunnel, Nozzle, Supersonic, Run-time, Schlieren

Published: March 2018

One of LAPAN’s programs is design and build the ramjet open tested wind tunnel. The lenght of pipe connecting between wind tunnel and storage tank was designed long enough so it was estimated there is big losses along the pipe. The object of this research is to calculation that losses, specially for the straight part only. The magnitude of the losses was gotten from simulation using software based on CFD theory. This research used two methods, i.e. based on pressure method and based on mass flow rate method. The simulation’s result using based on mass flow rate method gave the higher losses for the straight pipe so that result was chosen as the final result. That result was processed become the losses as a function of mass flow rate. The higher mass flow rate will produce the bigger losses. At mass flow rate of 60 kg/s, the losses is 0.135 %/m and at 100 kg/s the losses is 0.299 %/m. The relation between both parameter is close to linier curve. Key word:Pipe, losses, CFD, wind tunnel

Liner material

of case-bonded propellant rocket motor have been made by adding some filler to

the liner material composition used in free standing rocket motor. The liner

was manufactured by spinning method to the rocket motor tube. The case-bonded

liner performance in radial burning rocket motor was analyzed using material

characteristic test result combined with rocket motor burning mechanism and

free standing rocket motor static test result. The case-bonded liner materials

are superior to the free standing liner because it is lighter (18,94%) and have

higher heat resistance (6,75%). The application of case-bonded liner for radial

burning rocket motor using single configuration propellant will be safe because

the heat of propellant combustion passed through the isolator materials before

the rocket motor tube. Based on the analysis it is found that the case-bonded

liner can be recommended to the radial burning rocket motor using single

configuration propellant.

Relação entre modos de pensar e formas de falar no perfil conceitual de substância
Authors: Da Silva João Roberto Ratis Tenório , Nóbrega Joseane Jales dos Santos
Published: March 2018

Segundo a teoria do perfil conceitual existe uma relação entre modos de pensar e formas de falar. Este artigo teve como objetivo investigar essa relação no perfil conceitual de substância (zonas do perfil conceitual X gêneros de discurso). Investigamos 42 licenciandos em Química, que responderam um questionário para identificação de zonas do perfil conceitual. Em seguida, selecionamos 4 licenciandos que emergiram uma maior diversidade de zonas para a entrevista, em que tiveram que explicar situações que demandavam o uso do conceito de substância. Percebemos que a relação entre modos de pensar e formas de falar não é linear, mas mediada/regulada por outros elementos, como o nível de conhecimento e o ambiente no qual o indivíduo está inserido. Dessa forma, trabalhos que abordam proposição ou mapeamento de zonas de perfis conceituais devem lançar mão de mais de um instrumento de pesquisa, sendo o uso apenas de questionário ou entrevista limitado.
Panorama histórico da relação entre Filosofia e Química
Authors: Ribeiro Marcos Antonio Pinto
Published: March 2018

Química e filosofia tiveram pouco diálogo durante o século XX.  Esse trabalho investiga e organiza as principais relações entre estes dois campos de saber. Após a leitura de artigos da revista HYLE e FOUDATIONS OF CHEMISTRY, bem como de alguns filósofos da química centrais nessa temática, como o trabalho de Van Brakel, organizamos nosso panorama nos seguintes tópicos. Van Brakel defende uma pré-história da filosofia da química: de 1789 a 1990, marcado principalmente pela influência do legado de Kant e sua reavaliação no opus póstumos, Kant considerava a Química como uma arte sistemática, sem juízos a priori.  O anti-atomismo, principalmente de Ostwald e Dhuem também foi um capítulo dessa relação; no século XX Paul Dirac, especula sobre a possibilidade de completa redução da química à Fisica o que a destitui de problemas filosóficos genuínos; a química esteve presente na filosofia do emergentismo, no materialismo dialético e na tradição francesa. O século XX é caracterizado por Van Brakel por uma filosofia da química sem filósofos, ou seja, existem publicações assistemáticas de químicos com interesse em filosofia, por exemplo, Panet. A química começa a entrar na filosofia da ciência nos anos 60, principalmente com Tomas Khun; na década de 1990 é o nascimento da disciplina filosofia da química, um dos campos de maior crescimento na atualidade. No final, fazemos uma inferência desse debate para a Educação Química.

Published: March 2018

Background: B12 deficiency is a silent epidemic with serious consequences. Long term use of metformin has been associated with malabsorption of vitamin B12 leading to its deficiency along with increased homocysteine levels. With this background we designed this study to assess the status of vitamin B12 and its markers in type 2 diabetes mellitus patients on metformin therapy who are attending tertiary care hospital in the peripheral area of Pondicherry.Aims and Objective: The current study aims to study the relationship if any, between the glycemic status and the status of Vitamin B12 among T2DM patients on metformin therapy.Materials and Methods: A case control study was done with a sample size of 100 (50 case and 50 control). The patients were selected according to the inclusion criteria and their blood sample were analyzed for the various parameters. The markers of vitamin B12 status are studied among both the control and the patients with T2DM on metformin therapy and compared with their glycaemic status.Results: There is a significant increase in the levels of FBS, HbA1c, insulin and C-peptide in the study group. It was observed that the mean levels of homocysteine and Methylmalonic acid were significantly higher with lower levels of vitamin B12 in patients who were on metformin therapy.Conclusion: There is moderate correlation between the markers of B12 status and levels of fasting blood sugar as well as HbA1C. There is a significant correlation between insulin and C-peptide with the markers of vitamin B12 status.Asian Journal of Medical Sciences Vol.9(2) 2018 9-12
A hospital based study on clinico microbiological profile of neonatal septicemia
Authors: Ghosh Sumana , Basu Gandhari
Published: March 2018

Background: Globally, neonatal septicaemia is one of the common causes of neonatal death making it a grave problem. Timely diagnosis and adequate treatment is crucial for managing this burning issue.Aims and Objectives: Early detection of neonatal septicaemia along with its infective etiological agent(s) and assessment of antimicrobial sensitivity pattern.Materials and Methods: After getting approval from institutional ethics committee, an institution based observational, epidemiological study was conducted in ninety two neonates, clinically suspected for sepsis, admitted in neonatal intensive care unit (NICU) were included in the study. Written consent was obtained from their guardian. Blood was drawn from the neonates for estimating routine parameters and cultured for isolation of causative agents using standard protocol. Isolates were identified by staining and biochemical parameters.Results: The present study had 92 neonates, out of which 53 were male and 39 were female. Bad obstetric history (BOH) was present in 23 mothers. Low to very low birth weight was seen in more than two thirds culture positive neonates. All neonates (100%) had poor cry, sucking and reflex problems. 51(55.43%) were culture positive of which bacterial pathogens was detected in 27(52.94%) and fungal agents in 24 (47.05%) cases. Bacterial sepsis was predominantly caused by different gram negative organisms (66.66%). Klebsiella sp. and Staphylococcus sp. were the principal isolates. Candida was the commonest fungus reported. Klebsiella isolates were most sensitive to cefotaxime and amikacin while Staph. epidermidis isolates were sensitive to Amoxicillin clavulinic acid.Conclusion: This study was of immense help to the clinicians to minimise the neonatal mortality rate by early detection of causative agents and formulation of effective treatment.Asian Journal of Medical Sciences Vol.9(2) 2018 25-30

Keyhole retrosigmoid approach for large vestibular schwannomas: strategies to improve outcomes
Authors: Hoshide Reid , Faulkner Harrison , Teo Mario , Teo Charles
Published: March 2018

OBJECTIVE

There are numerous treatment strategies in the management for large vestibular schwannomas, including resection only, staged resections, resections followed by radiosurgery, and radiosurgery only. Recent evidence has pointed toward maximal resection as being the optimum strategy to prevent tumor recurrence; however, durable tumor control through aggressive resection has been shown to occur at the expense of facial nerve function and to risk other approach-related complications. Through a retrospective analysis of their single-institution series of keyhole neurosurgical approaches for large vestibular schwannomas, the authors aim to report and justify key techniques to maximize tumor resection and reduce surgical morbidity.

METHODS

A retrospective chart review was performed at the Centre for Minimally Invasive Neurosurgery. All patients who had undergone a keyhole retrosigmoid approach for the resection of large vestibular schwannomas, defined as having a tumor diameter of ≥ 3.0 cm, were included in this review. Patient demographics, preoperative cranial nerve status, perioperative data, and postoperative follow-up were obtained. A review of the literature for resections of large vestibular schwannomas was also performed. The authors’ institutional data were compared with the historical data from the literature.

RESULTS

Between 2004 and 2017, 45 patients met the inclusion criteria for this retrospective chart review. When compared with findings in a historical cohort in the literature, the authors’ minimally invasive, keyhole retrosigmoid technique for the resection of large vestibular schwannomas achieved higher rates of gross-total or near-total resection (100% vs 83%). Moreover, these results compare favorably with the literature in facial nerve preservation (House-Brackmann I–II) at follow-up after gross-total resections (81% vs 47%, p < 0.001) and near-total resections (88% vs 75%, p = 0.028). There were no approach-related complications in this series.

CONCLUSIONS

It is the experience of the senior author that complete or near-complete resection of large vestibular schwannomas can be successfully achieved via a keyhole approach. In this series of 45 large vestibular schwannomas, a greater extent of resection was achieved while demonstrating high rates of facial nerve preservation and low approach-related and postoperative complications compared with the literature.
Use of a flexible hollow-core carbon dioxide laser for microsurgical resection of vestibular schwannomas
Authors: Schwartz Marc S. , Lekovic Gregory P.
Published: March 2018

OBJECTIVE

The CO2 laser has been used on an intermittent basis in the microsurgical resection of brain tumors for decades. These lasers were typically cumbersome to use due to the need for a large, bulky design since infrared light cannot be transmitted via fiber-optic cables. Development of the OmniGuide cable, which is hollow and lined with an omnidirectional dielectric mirror, has facilitated the reintroduction of the CO2 laser in surgical use in a number of fields. This device allows for handheld use of the CO2 laser in a much more ergonomically favorable configuration, holding promise for microneurosurgical applications. This device was introduced into the authors’ practice for use in the microsurgical resection of skull base tumors, including vestibular schwannomas.

METHODS

The authors reviewed the initial 41 vestibular schwannomas that were treated using the OmniGuide CO2 laser during an 8-month period from March 2010 to October 2010. The laser was used for all large tumors, and select medium-sized tumors were treated via both the translabyrinthine and retrosigmoid approaches. The estimated time of tumor resection and estimated blood loss were obtained from operating room records. Data regarding complications, facial nerve and hearing outcomes, and further treatment were collected from hospital and clinic records, MRI reports, and direct review of MR images. Time of resection and blood loss were compared to a control group (n = 18) who underwent surgery just prior to use of the laser.

RESULTS

A total of 41 patients with vestibular schwannomas were surgically treated. The median estimated time of tumor resection was 150 minutes, and the median estimated blood loss was 300 ml. The only operative complication was 1 CSF leak. Thirty-eight patients had normal facial nerve function at late follow-up. The median MRI follow-up was 52 months, and, during that time, only 1 patient required further treatment for regrowth of a residual tumor.

CONCLUSIONS

The OmniGuide CO2 laser is a useful adjunct in the resection of large vestibular schwannomas. This device was used primarily as a cutting tool rather than for tumor vaporization, and it was found to be of most use for very large and/or firm tumors. There were no laser-associated complications, and the results compared favorably to earlier reports of vestibular schwannoma resection.
Endoscope-assisted middle fossa craniotomy for resection of inferior vestibular nerve schwannoma extending lateral to transverse crest
Authors: Master Adam N. , Roberts Daniel S. , Wilkinson Eric P. , Slattery William H. , Lekovic Gregory P.
Published: March 2018

OBJECTIVE

The authors describe their results using an endoscope as an adjunct to microsurgical resection of inferior vestibular schwannomas (VSs) with extension into the fundus of the internal auditory canal below the transverse crest.

METHODS

All patients who had undergone middle fossa craniotomy for VSs performed by the senior author between September 2014 and August 2016 were prospectively enrolled in accordance with IRB policies, and the charts of patients undergoing surgery for inferior vestibular nerve tumors, as determined either on preoperative imaging or as intraoperative findings, were retrospectively reviewed. Age prior to surgery, side of surgery, tumor size, preoperative and postoperative pure-tone average, and speech discrimination scores were recorded. The presence of early and late facial paralysis, nerve of tumor origin, and extent of resection were also recorded.

RESULTS

Six patients (all women; age range 40–65 years, mean age 57 years) met these criteria during the study period. Five of the 6 patients underwent gross-total resection; 1 patient underwent a near-total resection because of a small amount of tumor that adhered to the facial nerve. Gross-total resection was facilitated using the operative endoscope in 2 patients (33%) who were found to have additional tumor visible only through the endoscope. All patients had a House-Brackmann facial nerve grade of II or better in the immediate postoperative period. Serviceable hearing (American Academy of Otolaryngology–Head and Neck Surgery class A or B) was preserved in 3 of the 6 patients.

CONCLUSIONS

Endoscope-assisted middle fossa craniotomy for resection of inferior vestibular nerve schwannomas with extension beyond the transverse crest is safe, and hearing preservation is feasible.

Background: Maternal weight gain is influenced by several trends in perinatal health that are of great public health concern. Maternal weight gain during the 2nd and 3rd trimesters is an important determinant of fetal growthObjective: To determine the relationship between maternal weight gain and birth weight of baby at term.Methodology : A cross sectional observational study was carried among 50 pregnant women at term were admitted in the Department of Obstetrics and Gynaecology, Shaheed Suhrawardy Medical College and Hospital and Anwer Khan Modern Medical College hospital during the period of January 2014 to July 2014. Data were collected pre-designed data collection sheet.Results: This study found maximum (36%) were age group 21-25 years followed by 28% were 20 years, 24% were 26-30 years, 8% were 31-35 years and only 4% were 36-40 years. The average age was 25 years. Among these 50 pregnant women, 2 cases (4%) had BMI <18.5, 15 cases (30%) had a BMI 18.5- 24.9, 19 cases (38%) had a BMI 25-29.9 and 14 cases (28%) had a BMI ≥30. The mean birth weight was 2.77±0.33. kg. Mean weight gain was 10.72±3.72 Kg. Weight increased there was a corresponding increase in the mean birth weight and this relationship was statistically significant (<0.05).Conclusion: This study shows maternal weight gain significantly increased birth weight of the baby at term. Maternal weight should continue to be given importance in monitoring the health of pregnancies and bioelectrical impedance analysis and arm measurements should be further investigated as another simple way to track appropriate body composition changes across gestation, especially in resource-limited settings. Although challenging, public health efforts should continue working to improve the nutritional status of women of reproductive age before they conceive as an apparent way to improve birth outcomes.Anwer Khan Modern Medical College Journal Vol. 9, No. 1: Jan 2018, P 22-28
