Shipping is considered a primary vector of biological invasion. Hull fouling is recognized as one of the common vectors involved in the translocation of marine pests that may have deleterious impacts to ecology and economy. In an effort to understand the fouling communities within Brunei waters and as an early attempt to obtain baseline data, PVC plates were deployed at a depth of 1 meter, checked for taxa composition and replaced with new plates monthly and quarterly over a period of one year. The Caribbean bivalve Mytilopsis sallei was absent throughout the period of study, and plates were mainly colonized by native fouling species and silt. Nevertheless, further verification on the absence of Invasive Alien Species (IAS) is still required. This study summarizes the improved methods of analysis for better control and management in order to impede the incursion or invasion of undesirable species.

AbstractBased on both the pattern of year rings in a particular phalanx of adult male specimens of the common toad Bufo bufo and the thickness of this bone in first-year toads, the rate of resorption of year rings in each toad could be assessed. It appeared that this rate of resorption is small. Therefore the age of male specimens of Bufo bufo from the Netherlands can be determined for about 92% by counting the number of year rings in hematoxylin-stained cross-sections of this particular phalanx. This percentage can be raised to 93-98% by considering the year rings resorbed. The age of the remaining toads may be underestimated by not more than one year.

A survey on fouling using PVC panels was carried out for a period of one year in Yangon River. Additional observations on fouling of man-made structures elsewhere in Myanmar were also made in an effort to find marine alien invasive species. The Myanmar ports at Yangon, Sittway and Myeik have a long history of overseas trading with Europe since the 17th century. In addition, though the Yangon port and jetties are located upstream some 12 miles from the mouth of Yangon River, it experiences regular tidal action with seasonal brackish water conditions. Its catchment area is only 100 miles from the mouth and hence the river and its tributaries are short and small. Moreover, there are several weirs and small dams on the tributaries, which result in reduced sediment influx at the mouth and thus less turbidity. Therefore, the physiochemical conditions at Yangon port may not pose a limitation on the distribution of nuisance species that are able to survive brackish water conditions. Elsewhere, Sittway port at the mouth of the Kispanadi River also experiences regular tidal action and is directly connected to the Bay of Bengal, conditions which are favourable for the intrusion of marine nuisance species. Myeik port is located along the open shore of the Myeik, which is located near the Myeik Archipelago. The waters around the archipelago are clear and the shelf is characterized by high biodiversity. Therefore, the environment also appears to be highly favourable for alien invasive species. However, these ports have no record of the occurrence of alien invasive species in particular the Caribbean bivalve Mytilopsis sallei.

To find out the ability of Orobanche seeds to germinate immediately after seed set, seeds were germinated periodically at an interval of three months for one year in GR24. Some Orobanche seeds were capable of germination immediately after seed set but most required about nine months as after ripening or incubation period to be able to germinate. The phenomenon of after ripening in Orobanche seeds could be taken as an ecological measure to dormant over following unfavorable wet summer season. The growth hormone studies on Orobanche seed germination have shown that GA3 at a concentration of 100 ppm substantially enhanced seed germination when applied during pre-conditioning period. NAA showed some stimulatory effect at 0.5 - 1.0 ppm when applied during post-conditioning period but the hormone if applied during pre-conditioning period inhibited the germination. Kinetin failed to stimulate the germination at all the concentrations tested. Key words: Germination, root-parasite, hormone. Ecoprint Vol.11(1) 2004.

The results of the study of the duration of the juvenile period of indigenous Chechen willow leaf pear genotypes (Pyrus salicifolia Pall.) are given in connection with the acceleration of the breeding process and the use of selected forms in pear breeding for high precocity. The studies were carried out in 2016-2019 at OOO “Orchards of Chechnya” in accordance with the Agreement on creative cooperation with the Russian Research Institute of Fruit Crop Breeding. The work was carried out in accordance with generally accepted programs and methods. The objects of the study were one-year and two-year-old pear seedlings obtained from sowing seeds of selected dwarf and low-growing local Chechen forms of willow pear (P. salicifolia Pall.), laying fruit buds on annual growths and seedlings of Caucasian pear (P. caucasica Fed.), 20 500 pcs. of each specie. The aim of the research was to study the potential of precocity of willow pear seedlings and to reveal of selected forms with the greatest degree of this trait. Stratified seeds were sown in the sowing department of the OOO “Orchards of Chechnya” production nursery in April, 2017. The seedlings were grown according to the common technology in dryland conditions on the plot with chestnut soil. The first fl owering of plants was noted in the spring, 2019. As a result of the research, for the first time on a large number of the experimental material it was found that in the off spring of the indigenous Chechen willow leaf pear genotypes, the selection of a little more than 2% of seedlings with a very short juvenile period (2 years) was possible. They are of great interest in accelerating the breeding process and in the selection of new pear varieties with high precocity. 20 willow leaf pear genotypes were selected for the further use in breeding for high precocity and as sources of the trait of short juvenile period.

Abstract In crustaceans, ecdysis was long believed to result in the loss and replacement of all calcified structures, precluding the use of conventional ageing methods. However, the discovery of bands in the gastric ossicles of several crustaceans with some correlation with age suggests that direct age estimation may be possible. We applied this method to a tropical spiny lobster, Panulirus argus, one of the most iconic and economically valuable species in the Caribbean. The presence of growth bands was investigated using wild lobsters of unknown age and was validated with captive reared lobsters of known age (1.5–10 years) from the Florida Keys, Florida (USA). Bands were consistently identified in ptero- and zygo-cardiac ossicles of the gastric mill and did not appear to be associated with moulting. Validation with known age animals confirms that bands form annually. Counts between independent readers were reproducible with coefficients of variation ranging from 11% to 26% depending on reader experience and the structure used. This study demonstrates, for the first time, that direct age determination of P. argus is possible.

Abstract Background Balancing the intensity and duration of antiplatelet therapy according to thrombotic risk is a fundamental need in order to optimize therapy effectiveness and safety. Incorporation of new predictors in thrombotic risk stratification is therefore of a crucial importance for antiplatelet therapy net clinical benefit. Purpose The present analysis aimed to evaluate the relation of miR-126-3p and miR-223-3p, new markers of platelet activation, in order to facilitate prediction of recurrent thrombotic events after acute myocardial infarction (AMI). Method The analysis included 598 patients (age median 62 years, men 77.8%) randomized in the Prague-18 study (ticagrelor vs. prasugrel in AIM treated with primary PCI). During the study follow up, 40.6% of patients switched to clopidogrel. Determination of miR was evaluated 24 hours after admission; miR-126-3p and miR-223-3p were normalized by miR-423-3p and miR-150-5p. Quantitative determination of selected miRNAs was performed with a novel microRNA immunoassay method. Selected miRNAs were compared with key efficacy endpoints (cardiovascular death, nonfatal MI and stroke), stent thrombosis and all hemorrhagic events, and analysed using univariate and multivariate logistic regressions. Results Increased values of miR-223-3p were significantly related to the occurrence of combined ischemic endpoint within 30 days [OR (95% CI) 15.739 (2.066; 119.932) p=0.008] and within one year [3.175 (1.40; 7.186) p=0.006]. Decreased ratio of miR-126-3P/miR-223-3p was significantly related to the occurrence of combined ischemic endpoint within 30 days [0.137 (0.031; 0.609) p=0.009] and one year [0.372 (0.169; 0.819) p=0.014]. MiRNAs were identified as independent predictors even after adjustment for confounding clinical predictors (Study arm, Switch to Clopidogrel, Age, Men, BMI, Smoking, History of Hyperlipidemia, Hypertension, DM, MI, PCI, CABG, Chronic heart failure, Chronic renal failure, Peripheral arterial disease, LBBB, RBBB, TIMI <3 after PCI, Number of diseased vessels >1, Stem disease, Suboptimal of failure of PCI, Time to hospital). Adjusted ORs (95% CI) are 11.828 (1.472; 98.011), p=0.022 and 2.394 (1.021; 5.610), p=0.045 for increased value of miR-223-3p and the occurrence of combined ischemic endpoint within 30 days and one year respectively; 0.151 (0.030; 0.757), p=0.022 and 0.407 (0.179; 0.925), p=0.032 for decreased ratio of miR-126–3P/miR-223-3p and the occurrence of combined ischemic endpoint within 30 days and one year respectively. No association between miRNA and bleeding complications was identified. Conclusion The miR-223-3p and miR-126-3p to miR-223-3p ratio are strong independent predictors of thrombotic ischemic events and can be used to stratify patients post AMI.

Background:The observation of an intraluminal common carotid artery thrombus overlying a wall defect at ultrasonography or angiography is unusual. To our knowledge, there are no previous reports of a free-floating thrombus in the common carotid artery.Case Report:A 45-year-old woman who was previously healthy and on no medications presented with acute hemiparesis and aphasia. Following testing that included carotid duplex and trancranial Doppler ultrasonography, diffusion-weighted magnetic resonance imaging, and digital subtraction angiography, the patient underwent emergency open embolectomy. No underlying wall defect was seen at the time of imaging or surgery. No obvious hypercoagulable state could be identified. Her NIH Stroke Scale score improved from 26 at admission to 2 at three months and 1 at one year.Conclusions:Multimodal imaging may have improved diagnosis and management in this patient with a unique finding. The source of the thrombus remains obscure.

Objective. Diabetes care is an important part of family practice. Previous work indicates that diabetes management is variable. This study aimed to examine diabetes care according to best practices in one part of Ontario. Design and Participants. A retrospective chart audit of 96 charts from 18 physicians was conducted to examine charts regarding diabetes care during a one-year period. Setting. Grimsby, Ontario. Main Outcome Measures. Glycemic screening, control and management strategies, documentation and counselling for lifestyle habits, prevalence of comorbidities, screening for hypertension, hyperlipidemia, and use of appropriate recommended preventive medications in the charts were examined. Results. Mean A1c was within target (less than or equal to 7.00) in 76% of patients (ICC = −0.02), at least 4 readings per annum were taken in 75% of patients (ICC = 0.006). Nearly 2/3 of patients had been counselled about diet, more than 1/2 on exercise, and nearly all (90%) were on medication. Nearly all patients had a documented blood pressure reading and lipid profile. Over half (60%) had a record of their weight and/or BMI. Conclusion. Although room for improvement exists, diabetes targets were mainly reached according to recognized best practices, in keeping with international data on attainment of diabetes targets.

During the excavations of Messrs. Hogarth Grenfell and Hunt for the Egypt Exploration Fund in the winter of 1895–6 on the site of Karanis (Kom Ushim) in the Fayum, a considerable number of clay-sealings were found, mainly in the cellars of the Roman houses. These were recently put in my hands for investigation and offer some interesting material.The sealings have evidently come from various kinds of articles: in many instances the clay is too much broken for any determination of the shape which it had taken to be possible; but among the better preserved pieces are examples from the mouths of bottles, some of which have been squeezed down into the neck like a cork, others placed over a linen covering, sometimes tied down with cord: others are from the flat sides of wooden boxes, often showing the marks of cord: others again from parcels of irregular shape, in some cases seemingly wrapped in papyrus. The common points of all are that they consist of lumps of Nile-mud, and that they have been impressed, while the clay was damp, with signets, which were presumably those of the merchants who forwarded the goods upon which the sealings were placed.

AbstractIn this paper, a long-term equilibrium model of a local market is developed. Subject to minor qualifications, the model is arbitrage-free. The variables modelled are the prices of risk-free zero-coupon bonds – both index-linked and conventional – and of equities, as well as the inflation rate. The model is developed in discrete (nominally annual) time, but allowance is made for processes in continuous time subject to continuous rebalancing. It is based on a model of the market portfolio comprising all the above-mentioned asset categories. The risk-free asset is taken to be the one-year index-linked bond. It is assumed that, conditionally upon information at the beginning of a year, market participants have homogeneous expectations with regard to the forthcoming year and make their decisions in mean-variance space. For the purposes of illustration, a descriptive version of the model is developed with reference to UK data. The parameters produced by that process may be used to inform the determination of those required for the use of the model as a predictive model. Illustrative results of simulations of the model are given.
