Golden Horn Estuary: Description of the ecosystem and an attempt to assess its ecological quality status using various classification metrics

In this paper, we describe the pelagic and benthic ecosystem of the Golden Horn  estuary opening into the Marmara Sea. To improve the water quality of the estuary, which had long been subject to severe anthropogenic pollution (industrial, chemical, shipping),  industrial facilities were moved from the estuary in the 1980s, followed by a rehabilitation plan in the 1990s. Our results, based on chemical parameters and phytoplankton showed some signs of improvement of water conditions in the upper layer. However, macrozoobenthic findings of this study did not reflect such a recovery in bottom life.An approach to the Ecological Quality Status (EQS) assessment was performed by applying the biotic indices BENTIX, AMBI, BOPA, BO2A. Our final assessment was based on 'expert-judgements' and revealed a very disturbed overall ecosystem with 'bad' EQS for the station at the head of the estuary,  'poor' in the rest of the estuary and 'moderate' EQS only in the middle station

Phytoplankton composition related to the environmental conditions in the coastal waters of the Gulf of Erdek

1545-1559Seasonal changes of phytoplankton communities in the coastal waters of the Gulf of Erdek from November 2006 to August 2008 were examined in relation to some environmental variables and 95 species from 6 different algae groups were identified. In addition, two species were recorded for the first time in the Turkish coastal waters and one species for the Sea of Marmara. The maximum total phytoplankton abundance (1.99 × 105 cells L-1) were observed in May 2008, with Pseudo-nitzschia sp. being the most dominant species of that month (1.52 × 105 cells L-1). Both the Bray-Curtis diversity index and the Euclidean distance indicated that the upper and lower water layers were separated from each other at the stations, and the Spearman’s rank-correlation and CCA analyses also showed that environmental variables affected the abundance of species. Furthermore, according to the CCA diagram, especially the temperature and dissolved oxygen had a bigger impact on the distribution of species. The Shannon-Wiener diversity index (Hʹ) values were low when Pseudo-nitzschia sp., Prorocentrum micans, Gymnodinium sp. and Prorocentrum scutellum were dominant over other species in the sampling period

Penyuluhan Bahaya Stunting di Posyandu Mawar Indah Kelurahan Balik Alam Kecamatan Mandau Kabupaten Bengkalis Riau

Stunting atau kerdil didefinisikan sebagai kondisi gagal tumbuh pada anak yang mengakibatkan anak mengalami kekurangan gizi dalam waktu yang lama, sehingga anak lebih pendek dari anak normal seusianya dan memiliki keterlambatan dalam berpikir. Prevalensi stunting di Indonesia pada saat ini menunjukkan angka 24,4% atau sekitar 5,33 juta balita dimana angka ini mengalami penurunan dibandingkan angka kejadian tahun sebelumnya. Untuk mengurangi angka kejadian stunting ini pemerintah melakukan berbagai upaya dimana salah satu programnya yaitu dengan melakukan penyuluhan ataupun sosialisasi tentang pentingnya pengetahuan stunting bagi dampak tumbuh kembang anak. Dalam pencapaian tersebut mahasiswa Kukerta Balik Alam Universitas Riau menyelenggarakan penyuluhan bahaya stunting di lokasi pengabdian yang berada di Kelurahan Balik Alam, Kecamatan Mandau, Kabupaten Bengkalis. Kegiatan penyuluhan ini diikuti oleh ibu hamil dan ibu yang memiliki balita di Posyandu Mawar Indah. Hasil dari kegiatan ini diharapkan dapat menunjukkan penurunan angka stunting yang signifikan

Evaluation of trace elements in Malay women with type 2 diabetes mellitus

Trace elements are essential for human health. This study determines the level of chromium (Cr), zinc (Zn), selenium (Se), copper (Cu), ferrum (Fe) and manganese (Mn) in the hair and nails of married Malay women with type 2 diabetes mellitus from Hulu Langat, Selangor, Malaysia. The trace elements were analysed using inductively coupled plasma mass spectrometry (ICP-MS) after an acid digestion treatment. The levels of all trace elements measured were higher in the hair samples than in nails except for Se. Mean levels of Zn and Se were significantly higher in the hair of non-working women (84.91 ± 10.32 μg/g and 0.42 ± 0.15 μg/g, respectively) compared to working women (64.98 ± 11.10 μg/g and 0.30 ± 0.18 μg/g). Copper levels in hair were significantly higher among women with good and satisfactory diabetes control (20.41 ± 4.20 μg/g) compared to the poor diabetes control group (15.67 ± 4.31 μg/g). However, a contradictory result was obtained from the nails of women with good and satisfactory diabetes control with a Cu level of 3.35 ± 0.46 μg/g and 4.69 ± 0.33 μg/g for the poor diabetes control group. In hair samples, significant positive correlations were obtained with Cr-Cu (r = 0.55), Zn-Mn (r = 0.46) and Se-Mn (r = 0.38). In nails, significant positive correlations were also obtained between Cr-Zn (r = 0.31), Zn-Fe (r = 0.30) and Fe-Mn (r = 0.47). In conclusion, age, educational status, number of children and duration of diabetes did not influence trace elements levels

Bisbibenzyls, a New Type of Antifungal Agent, Inhibit Morphogenesis Switch and Biofilm Formation through Upregulation of DPP3 in Candida albicans

The yeast-to-hypha transition plays a crucial role in the pathogenesis of C. albicans. Farnesol, a quorum sensing molecule (QSM) secreted by the fungal itself, could prevent the formation of hyphae and subsequently lead to the defect of biofilm formation. The DPP3, encoding phosphatase, is a key gene in regulating farnesol synthesis. In this study, we screened 24 bisbibenzyls and 2 bibenzyls that were isolated from bryophytes or chemically synthesized by using CLSI method for antifungal effect. Seven bisbibenzyls were found to have antifungal effects with IC80 less than 32 µg/ml, and among them, plagiochin F, isoriccardin C and BS-34 were found to inhibit the hyphae and biofilm formation of C. albicans in a dose-dependent manner. To uncover the underlying relationship between morphogenesis switch and QSM formation, we measured the farnesol production by HPLC-MS and quantified Dpp3 expression by detecting the fluorescent intensity of green fluorescent protein tagged strain using Confocal Laser Scanning microscopy and Multifunction Microplate Reader. The DPP3 transcripts were determined by real-time PCR. The data indicated that the bisbibenzyls exerted antifungal effects through stimulating the synthesis of farnesol via upregulation of Dpp3, suggesting a potential antifungal application of bisbibenzyls. In addition, our assay provides a novel, visual and convenient method to measure active compounds against morphogenesis switch

A rapid and sensitive system for recovery of nucleic acids from Mycobacteria sp. on archived glass slides

The field of diagnostics continues to advance rapidly with a variety of novel approaches, mainly dependent upon high technology platforms. Nonetheless much diagnosis, particularly in developing countries, still relies upon traditional methods such as microscopy. Biological material, particularly nucleic acids, on archived glass slides is a potential source of useful information both for diagnostic and epidemiological purposes. There are significant challenges faced when examining archived samples in order that an adequate amount of amplifiable DNA can be obtained. Herein, we describe a model system to detect low numbers of bacterial cells isolated from glass slides using (laser capture microscopy) LCM coupled with PCR amplification of a suitable target. Mycobacterium smegmatis was used as a model organism to provide a proof of principle for a method to recover bacteria from a stained sample on a glass slide using a laser capture system. Ziehl-Neelsen (ZN) stained cells were excised and catapulted into tubes. Recovered cells were subjected to DNA extraction and pre-amplified with multiple displacement amplification (MDA). This system allowed a minimum of 30 catapulted cells to be detected following a nested real-time PCR assay, using rpoB specific primers. The combination of MDA and nested real-time PCR resulted in a 30-fold increase in sensitivity for the detection of low numbers of cells isolated using LCM. This study highlights the potential of LCM coupled with MDA as a tool to improve the recovery of amplifiable nucleic acids from archived glass slides. The inclusion of the MDA step was essential to enable downstream amplification. This platform should be broadly applicable to a variety of diagnostic applications and we have used it as a proof of principle with a Mycobacterium sp. model system
