KORELASI ANTARA UMUR INKUBASI DENGAN TAHAP PERKEMBANGAN EMBRIO Chelonia mydas YANG DIINKBASI PADA SUHU INKUBASI YANG BERBEDA
Authors: Bahri Syamsul 
Published: January 2018

Abstrak: Kecepatan perkembangan embrio Chelonia mydas dipengaruhi oleh suhu inkubasi. Embrio yang diinkubasi pada suhu 31ÃÂ±1ÃÂ°C (SF)ÃÂ mencapai tahap 17 pada umur inkubasi 22-23 hari, tahap 19 pada umur inkubasi 26 hari, dan tahap 22 pada umur inkubasi 31 hari. Embrio yang diinkubasi pada suhu 26ÃÂ±1ÃÂ°C (SM)ÃÂ mencapai tahap tahap 17 pada umur inkubasi 39-40 hari, tahap 19 pada umur inkubasi. 45 hari, dan tahap 22 pada umur inkubasi 52-53 hari. Hasil pengamatan terhadap struktur histologis gonad embrio menunjukkan bahwa gonad embrio tahap 17, 19, dan tahap 22 telah berupa gonad indiferen. Gonad-gonad pada tahap tersebut sudah dapat dibedakan menjadi bagian korteks dan bagian medula. Bagian korteks berupa epitel selapis silindris, sedangkan bagian medula mengandung jaringan ikat dan kelompok-kelompok sel. Bakal sel kelamin ditemukan pada bagian medula dan korteks. Dengan demikian dapat disimpulkan bahwa periode TSP Chelonia mydas yang diinkubasi pada suhu 31ÃÂ±1ÃÂ°C (SF)ÃÂ ÃÂ terentang dari umur inkubasi 22 hari hingga umur inkubasi 31 hari, sedangkan periode TSP Chelonia mydas yang diinkubasi pada suhu 26ÃÂ±1ÃÂ°C (SF)ÃÂ ÃÂ terentang dari umur inkubasi 39 hari hingga umur inkubasi 53 hari.Kata kunci: Chelonia mydas, TSP, umur inkubasi, suhu feminisasi, suhu maskulinisasiÃÂ Abstract: Embryonic development Rate of Chelonia mydas is affected by incubation temperature . The embryos were incubated at 31 ÃÂ± 1ÃÂ°C ( FT ) reached embryonic stage of 17th at 22-23rd of incubation day, embryonic stage of 19th at 26th of incubation day, and embryonic stage of 22nd at 31st of incubation day. The embryos were incubated at 26 ÃÂ± 1ÃÂ°C ( MT ) reached embryonic stage 17 th at 39-40th incubation day , embryonic stage 19 th at 45 th day of incubation , and embryonic stage 22nd at 52-53 rd incubation day. Observations on the histological structure of the gonadal embryos showed that the embryonic gonad stages 17th , 19th , and 22nd have been in indifferent stage. Gonads at this stage can be distinguished ÃÂ in two parts, cortex and medulla. Cortex as a layer of cylindrical epithelium, while the medulla consist of connective tissue andÃÂ groups of cell. Primordial Germ Cells are found both in medulla and cortex . It can be concluded that the TSP of Chelonia mydas were incubated at 31 ÃÂ± 1ÃÂ°C ( FT ) extended from 22nd ofÃÂ incubation day until the 31st of incubation day , whereas the TSP of Chelonia mydas were incubated at 26 ÃÂ± 1ÃÂ°C (MT) extended from 39th ofÃÂ incubation day until the 53rd of incubation day.Key words: Chelonia mydas, TSP, feminization temperature, maskulinization temperature

The Role of Quantitative C-Reactive Protein, White Blood Cell Count and Pyuria in Predicting Urinary Tract Infection among Febrile Infants and Children
Authors: Rimal Hem Sagar , Walavalkar Shripad J 
Published: January 2018

Introduction: Urinary tract infection (UTI) is among the commonest bacterial infections in infants and children that warrants early detection and management to prevent long term consequences in kidney causing significant morbidity. The prevalence of UTI varies according to age, gender, race, circumcision status of children but it occurs in 1% of boys and 1 to 3% of girls. There have been studies that have highlighted the importance of C-reactive as an inflammatory marker involved during urinary tract infection in children.Objectives: To find out how Quantitative C-reactive protein level, white blood cell count and pus cells in urine are associated in febrile infants and children with UTI. To find out the antibiotic sensitivity pattern of UTI.Methodology: A prospective cross sectional study was conducted to evaluate febrile infants and children of 2 months to 13 years of age with suspected UTI for a period of six months. Venous blood samples were sent for Quantitative estimation of CRP, White blood cell count and urine samples were sent for urine microscopy and culture sensitivity. Statistical analysis of data was done using SPSS software version 16.Results: Among 210 infants and children enrolled in the study, 62 (29.55%) had positive urine culture, representing 31.2% and 28.6% of female and male populations respectively. The sensitivity, specificity, positive predictive value(PPV) and negative predictive(NPV) value of CRP (with cut off of 1mg/dl) was 77%,81%, 63% & 90% respectively and that of WBC Count (with cut off of > 12000/ml ) were 56%, 88%, 66% & 83% respectively. Similarly for pyuria (with cut off of >10/HPF) using urine culture as gold standard were 63%, 91%,74% and 85% respectively. The most common organism found in urine culture was E. coli 49(79%). Highest number of isolates were sensitive to Nitrofurantoin(96%) and Amikacin(94%) whereas Amoxycillin was resistant to all the organism tested that was the resistance of 100%.The next common antibiotics found to be resistant was cotrimoxazole (70%).Conclusion: Quantitative C- reactive protein and White blood cell count in blood are very useful markers to predict UTI in febrile infants and children. E coli is the commonest pathogen to cause UTI and Pyuria(pus cells > 10/HPF) has high predictive value for UTI. Birat Journal of Health SciencesVol.2/No.3/Issue 4/Sep- Dec 2017, Page: 296 - 299
A novel scale for describing visual outcomes in patients following resection of lesions affecting the optic apparatus: the Unified Visual Function Scale
Authors: Makarenko Serge , Ye Vincent , Gooderham Peter A. , Akagami Ryojo 
Published: January 2018

OBJECTIVEHistorically, descriptions of visual acuity and visual field change following intracranial procedures have been very rudimentary. Clinicians and researchers have often used basic descriptions, such as “improved,” “worsened,” and “unchanged,” to describe outcomes following resections of tumors affecting the optic apparatus. These descriptors are vague, difficult to quantify, and challenging to apply in a clinical perspective. Several groups have attempted to combine visual acuity and visual fields into a single assessment score, but these are not user-friendly. The authors present a novel way to describe a patient’s visual function as a combination of visual acuity and visual field assessment that is simple to use and can be used by surgeons and researchers to gauge visual outcomes following tumor resection.METHODSVisual acuity and visual fields were combined into 3 categories designed around the definitions of legal blindness and fitness to drive in Canada. The authors then applied the scale (the Unified Visual Function Scale, or UVFS) to their previously published case series of perisellar meningiomas to document and test overall visual outcomes for patients undergoing tumor resection. The results were compared with previously documented visual loss scales in the literature.RESULTSUsing the UVFS the authors were able to capture the overall visual change; the scale was sensitive enough to define the overall visual improvement or worsening quantitatively, using categories that are clinically relevant and understandable.CONCLUSIONSThe UVFS is a robust way to assess a patient’s vision, combining visual fields and acuity. The implementation of pre- and postoperative assessment is sensitive enough to assess overall change while also providing clinically relevant information for surgeons, and allows for comparisons between treatment groups.

Published: January 2018

OBJECTIVESeveral randomized trials have been focused on patients with anterior circulation stroke, whereas few data on posterior circulation stroke are available. Thus, new mechanical thrombectomy (MT) strategies, including a direct-aspiration first-pass technique (ADAPT), remain to be evaluated in basilar artery occlusion (BAO) patients. The authors here assessed the influence of reperfusion on outcome in BAO patients and examined whether ADAPT improves the reperfusion rate compared with stent retriever devices.METHODSThree comprehensive stroke centers prospectively collected individual data from BAO patients treated with MT. Baseline characteristics as well as radiographic and clinical outcomes were compared between the 2 MT strategies. The primary outcome measure was the rate of successful reperfusion, defined as a modified Thrombolysis in Cerebral Infarction (mTICI) grade of 2b–3. Favorable outcome was defined as a 90-day modified Rankin Scale score of 0–2.RESULTSAmong the 100 adult patients included in the study, 46 were treated with first-line ADAPT (median age 61 years, IQR 53–71 years; stent-retriever rescue therapy was secondarily used in 12 [26.1%]) and 54 were treated with a primary stent retriever (median age 67 years, IQR 53–78 years). There was no difference in baseline characteristics between the 2 treatment groups, except for the rate of diabetes (19.6% vs 5.7%, respectively, p = 0.035). Successful reperfusion was achieved in 79% of the overall study sample. Overall, the rate of favorable outcome was 36.8% and 90-day all-cause mortality was 44.2%. Successful reperfusion positively impacted favorable outcome (OR 4.57, 95% CI 1.24–16.87, p = 0.023). A nonsignificant trend toward a higher successful reperfusion rate (unadjusted OR 2.56, 95% CI 0.90–7.29, p = 0.071) and a significantly higher rate of complete reperfusion (mTICI grade 3; unadjusted OR 2.59, 95% CI 1.14–5.86, p = 0.021) was found in the ADAPT group. The procedure duration was also significantly lower in the ADAPT group (median 45 minutes, IQR 34 to 62 minutes vs 56 minutes, IQR 40 to 90 minutes; p = 0.05), as was the rate of periprocedural complications (4.3% vs 25.9%, p = 0.003). Symptomatic intracranial hemorrhage (0.0% vs 4.0%, p = 0.51) and 90-day all-cause mortality (46.7% vs 42.0%, p = 0.65) were similar in the 2 groups.CONCLUSIONSAmong BAO patients, successful reperfusion is a strong predictor of a 90-day favorable outcome, and the choice of ADAPT as the first-line strategy achieves a significantly higher rate of complete reperfusion with a shorter procedure duration.
Rôle de l'érosion différentielle dans la genèse de la dépression calcaire de Tralée (Comté de Kerry, Irlande)
Authors: Saucerotte Michèle 
Published: January 2018

The Tralee district, county of Kerry, South-West Ireland, offers an interesting Appalachian style landscape. It probably derives from an old erosion surface which has been dismantled and deformed by tectonic movements until a very recent time (late Tertiary ?) in connection with the Atlantic Ocean opening and the evolution of the Porcupine Seabight.
Under the Mesozoïc and Cenozoïc tropical climates, the Carboniferous limestone was deeply eroded down to a lower level of erosion, between two escarpments built in shales or sandstones. During the Quaternary cold climates, the Namurian shales were much faster eroded and their scarp receded quickly.

Geomorphology of the Channel Tunnel area in Northern France.
The terminal route and site of the Channel Tunnel in french territory are located in a border area between the North Sea coastal plain and the Boulonnais highlands. The relief is corresponding to morphostructural conditions wich are related to weald-like geomorphology. Three geomorphological units are distinguished : the inner chalky region with loess cover, the ancient fossil cliff of Sangatte with pleistocene deposits, the border of the peaty costal plain which is deeply infilled by pleistocene and holocene formations.
Malte : un archipel entre tourisme balnéaire et tourisme culturel au coeur de la méditerranée
Authors: Scol Jean 
Published: January 2018

Au cœur de la Méditerranée, l'archipel maltais s'offre aux touristes, surtout européens du nord et du nord-ouest, en destination insulaire subtropicale de proximité. À l'image de nombreuses destinations de la région, Malte attire donc avant tout pour son climat et l'espoir d'y retrouver les joies du tourisme balnéaire. Or les plages y sont plutôt rares et c'est du côté de son patrimoine culturel particulièrement riche et varié et de quelques sites naturels spectaculaires qu'il faut rechercher la matière touristique la plus convaincante. Concernant les flux de visiteurs étrangers, ceux-ci sont dominés par les britanniques. Cependant, si le tourisme de séjour a enregistré une forte croissance jusqu'au milieu des années 1990, celle-ci s'est depuis essoufflée et c'est surtout grâce à la croissance significative du nombre de croisiéristes que Malte continue malgré tout de voir augmenter celui des visiteurs.
La destination, comme d'autres dans l'espace méditerranéen, a semble-t-il atteint son stade de maturité touristique ; une étape du développement que les autorités locales en charge du tourisme tentent de négocier par le passage d'une politique jusqu'alors surtout quantitative à une logique plus qualitative en adéquation avec les objectifs du développement durable.
