Abstract This article examines the image of Mary’s womb as the bridal chamber in which the Word and the flesh, the divine and the human natures of Christ, are united. The image presents the reader with a paradox – the Word and the flesh engage in a divine unification and comingling in the womb of the virgin. The study traces the development of the image in the earlier works of Augustine, and contextualises it within Augustine’s later thought, in which the body and sexuality are considered in a more positive light. The study aims to demonstrate that Augustine’s structuring of incarnational theology served as a framework for his views on sexuality – prelapsarian, postlapsarian, and eschatological sexuality – and the discourse of the incarnation, especially in his later thought, should be seen primarily as a discourse of sexuality.

Full textAbstract:
Scholars have long seen that Horace's treatment of Homer in this Epistle demands to be read in the tradition of moral allegory in which Ulysses becomes the type of the ‘man of virtue’ (‘rursus quid virtus et quid sapientia possit / utile proposuit nobis exemplar Ulixen’, 17–18): on such a reading, Circe becomes an allegory of foolish passion ‘to which Ulysses’ companions give in through their stultitia, and because of which they lose their reason and become no better than animals. Antisthenes, from whose writings such an allegorising approach probably developed, was regarded as an early Cynic, and the idea became the special province of Cynic-Stoic philosophy; scholars have therefore felt justified in seeing this epistle as a criticism of Epicureanism, represented by the sponsi Penelopae, nebulones, Alcinoique … iuventus, from the point of view of a Cynic or a syncretistic Stoic.

Full textAbstract:
Uncontrolled bleeding is the main cause of mortality from trauma. Collagen has been developed as an important hemostatic material due to its platelet affinity function. A bath sponge skeleton is rich in collagen, also known as spongin. To understand the hemostatic effect of spongin, spongin materials, SX, SFM and SR were prepared from the bath sponge Spongia officinalis, and hemostatic experiments were performed. The SX, SFM and SR were significantly better than the positive control, type I collagen, in shortening the whole blood clotting time in vitro and hemostasis upon rat tail amputation. In a hemostatic experiment of rabbit common carotid artery injury, the hemostatic time and 3 h survival rate of the SFM group were 3.00 ± 1.53 min and 100%, respectively, which are significantly better than those of the commercial hemostat CELOX-A (10.33 ± 1.37 min and 67%, respectively). Additionally, the SFM showed good coagulation effects in platelet-deficient blood and defibrinated blood, while also showing good biocompatibility. Through a variety of tests, we speculated that the hemostatic activity of the SFM is mainly caused by its hyperabsorbency, high affinity to platelets and high effective concentration. Overall, the SFM and spongin derivates could be potential hemostatic agents for uncontrolled bleeding and hemorrhagic diseases caused by deficiency or dysfunction of coagulation factors.

Sponges are one of the most influential benthic organisms in coral reef ecosystems. Many studies on sponge communities have been carried out globally, from the tropics to the sub-tropics. However, in Indonesia, the sponge community has not been sufficiently observed, especially its diversity and interactions with habitats. Manokwari, a developing city north of the Bird's Head Seascape region, Papua has a lack of information on benthic communities and no reports of sponges. This study is to examine the sponge community (diversity and distribution) in coral reef ecosystem. This study found that sponge richness (species and morphology) was categorized as “low”, with only 11 species with 8 morphological forms. The most common species included Niphates erecta, Stylissa carteri, and Pseudoceratina purpurea, while the most common growth forms were massive and encrusting, accounting respectively for 27.3% and 18.2% of the total number of species. The highest diversity was found on the island of Kaki (5 species) with the island of Nusmapi having an uneven distribution of sponges. The results of our study found that there was no relationship between sponge diversity and morphology. This baseline information is essential for management of marine biodiversity hotspots in taking decisions for marine life conservation. Spons merupakan salah satu organisme bentik yang paling berpengaruh dalam ekosistem terumbu karang. Banyak penelitian tentang komunitas spons telah dilakukan secara global, dari daerah tropis hingga sub tropis. Namun di Indonesia, komunitas spons belum cukup diamati, terutama keanekaragaman dan interaksinya dengan habitat. Manokwari, kota berkembang di utara dari wilayah Bentang Laut Kepala Burung (BLKB), Papua memiliki kekurangan informasi tentang komunitas bentik dan tidak ada laporan tentang spons. Studi ini untuk mengkaji komunitas spons (keanekaragaman dan distribusi) pada ekosistem terumbu karang. Penelitian ini menemukan kekayaan spons (spesies dan morfologi) yang dikategorikan “rendah”, dengan hanya 11 spesies dengan 8 bentuk morfologi. Spesies yang paling umum termasuk Niphates erecta, Stylissa carteri, dan Pseudoceratina purpurea, sedangkan bentuk pertumbuhan yang paling umum adalah massif dan encrusting dengan menyumbang masing-masing 27,3% dan18,2% dari total jumlah spesies. Keanekaragaman tertinggi ditemukan di pulau Kaki (5 spesies) dengan pulau Nusmapi memiliki sebaran spons tidak merata. Hasil penelitian kami menemukan tidak ada hubungan antara keanekaragaman spons dengan bentuk morfologi. Informasi dasar ini sangat penting untuk pengelolaan hotspot keanekaragaman hayati dalam perumusan keputusan untuk konservasi biota laut.

Abstract The Influence of nutrient and temperature to the antibacterial selectivity of Sponge Associated-Bacteria Production of pharmacological activity by marine microorganism is strongly influenced by nutrition and environmental conditions. In this study would discuss about the influence of several type of media to the production of antibacterial agent by sponge-. associated microorganisms. About 3 sponges tissue Theonella sp, Callispongia sp. and Lithistide sp. collected from Seribu Island will be used for the host of associated microorganism. Agar medium used for isolation were M1 that contained amylum, yeast extract and peptone, M2 (10% marine broth media) contained yeast extract and peptone, M3 only sea water without adding any nutrients. Beside the nutrient variation, heat sock treatment at 50oC toward the sponge solution also apply to this study. The bacterial isolation data indicated that bacterial density in (CFU/100µL) of Theonella sp, Callispongia sp. and Lithistide sp. were minimum when spreading in M3 medium with heat sock treatment. This data showed that limiting in nutrient and heating could increasing bacterial selectivity. The antibacterial activity capability of bacterial strains isolated using M1, M2 and M3 respectively in range were 81,8-90,9%; 50-87,5% and; 66,7 -100%. This results showed that less nutrient of media will rise the number of antibacterial activity strains,and decreasing of bacterial density. This study reported that the minimum nutrient of isolation media and heat shock treatment could be used for selecting the antibacterial strains of sponge associated bacteria. Keywords : isolation media, antibacterial, nutrient, microbial symbiont AbstrakAktifitas farmakologi yang dihasilkan oleh mikroorganisme laut sangat dipengaruhi oleh nutrisi dan kondisi lingkungan. Hal tersebut mendorong untuk digali lebih dalam tentang aspek-aspek yang mempengaruhi seleksi mikroba potensial pada spons. Metode isolasi mikroba dari jaringan spons menjadi kunci dalam menguak potensi mikroba simbionnya. Dalam penelitian ini akan membahas pengaruh berbagai media isolasi bakteri yang berasosiasi dengan spons asal Kep. Seribu. Terhadap 3 specimen spons Theonella sp., Callispongia sp. dan Lithistide sp. dilakukan isolasi bakteri dengan metode direct sampling menggunakan media M1, M2 dan M3. Media M1 mengandung nutrisi antara lain amilum, ekstrak khamir dan pepton, sedangkan media M2 mengandung sumber nutrisi ekstrak khamir dan pepton dan M3 hanya media agar dan air laut. Selain variasi nutrient dalam media, perlakuan pemanasan pada suhu 50oC juga akan dilakukan terhadap larutan sampel spons sebelum dilakukan penyebaran pada media isolasi. Hasil isolasi bakteri yang diisolasi spons Theonella sp, Callispongia sp. dan Lithistide sp. menunjukkan bahwa kepadatan minimum diperoleh dengan menggunakan media M3 dengan perlakuan pemanansan. Dari data isolasi bakteri menunjukkan bahwa selain kandungan nutrient yang minimum, perlakuan pemanasan akan menurunkan kepadatan jumlah bakteri yang tumbuh, sehingga pemanasan merupakan salah satu cara dalam seleksi isolasi bakteri yang berasosiasi dengan spons. Hasil analisis aktivitas antibakteri menunjukkan bahwa persentase strain-strain bakteri yang aktif terhadap antimikroba Vibrio eltor, Eschericia coli dan Bacillus subtilis dengan variasi media M1 berkisar antara 81,8-90,9%; M2 berkisar 50-87,5% dan M3 berkisar 66,7-100%. Dari data tersebut disimpulkan bahwa semakin sedikitnya nutrisi media isolasi maka semakin tingginya mikroba-mikroba potensial penghasil antibiotik. Media M3 merupakan media yang selektif untuk isolasi mikroba potensial dari spons, terbukti dengan tingginya prosentase bakteri yang aktif dan berkurangnya jumlah koloni yang tumbuh.Kata kunci : media isolasi, antibakteri, nutrisi, mikroba simbion

Full textAbstract:
A holdfast is a root- or basal plate-like structure of principal importance that anchors aquatic sessile organisms, including sponges, to hard substrates. There is to date little information about the nature and origin of sponges’ holdfasts in both marine and freshwater environments. This work, to our knowledge, demonstrates for the first time that chitin is an important structural component within holdfasts of the endemic freshwater demosponge Lubomirskia baicalensis . Using a variety of techniques (near-edge X-ray absorption fine structure, Raman, electrospray ionization mas spectrometry, Morgan–Elson assay and Calcofluor White staining), we show that chitin from the sponge holdfast is much closer to α-chitin than to β-chitin. Most of the three-dimensional fibrous skeleton of this sponge consists of spicule-containing proteinaceous spongin. Intriguingly, the chitinous holdfast is not spongin-based, and is ontogenetically the oldest part of the sponge body. Sequencing revealed the presence of four previously undescribed genes encoding chitin synthases in the L. baicalensis sponge. This discovery of chitin within freshwater sponge holdfasts highlights the novel and specific functions of this biopolymer within these ancient sessile invertebrates.

Full textAbstract:
Substrate stability could influence abundance and size patterns of benthic organisms and thus affect community structure. Sponges on coral reefs are often found growing on calcareous rock and rubble that vary in stability, with loose rubble more easily moved by water flow, which is typically strongest in shallower water. Using the common Indo-Pacific sponge, Coscinoderma matthewsi (Lendenfeld, 1886), the present study examines the interaction of substrate type and depth (6 and 12m) on sponge abundance, size, morphology and skeletal properties (i.e. spongin fibres). Coscinoderma matthewsi was three times less common at 6m, with most sponges at this depth attached to rock, even though rubble had higher percentage cover. Mean sponge length, width and height were all greatest at 12m, with sponges growing largest on rock, probably because it is a more stable substrate for survival and growth. Morphology varied between depths, with most C. matthewsi individuals at 6m having a massive shape, whereas many sponges at 12m grew large lobes; this increases their surface area and possibly promotes filtration. Spongin density, length and width varied greatly among individuals; however, there was no consistent pattern across depth.

Keywords: Ianthella basta, antimicrobial, Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa, Candida albicans. ABSTRAKSpons adalah hewan metazoa multiseluler tergolong ke dalam filum Porifera, yang memiliki perbedaan struktur dengan metazoan lainnya. Tujuan penelitian ini ialah untuk mengetahui apakah ekstrak etanol dari organisme laut spons Ianthella basta memiliki aktivitas antimikroba terhadap beberapa mikroba patogen Escherichia coli, Staphylococcus aureus, Pseudomonas aeruginosa dan Candida albicans. Metode ekstraksi yang digunakan adalah maserasi dengan pelarut etanol 96%. Metode yang digunakan yaitu Metode Difusi (Disc Diffusion Kirby and Bauer). Pengujian aktivitas antimikroba ini menggunakan kertas cakram (paper disc) berukuran 6 mm dengan daya serap 50 µL tiap cakram. Hasil ekstrak kasar etanol Spons Ianthella basta dari semua mikroba uji yaitu Escherichia coli, Staphylococcus aureus, Pseudomonas aeruginosa dan Candida albicans, terlihat yang memberikan daya hambat paling besar terdapat pada bakteri Staphylococcus aureus dengan jumlah rata – rata zona hambat yaitu 7,00 mm dengan kategori sedang. Hasil penelitian yang diperoleh menunjukkan bahwa ekstrak kasar dari Spons Ianthella basta memiliki aktivitas antimikroba karena mampu menghambat pertumbuhan mikroba uji Staphylococcus aureus, Escherichia coli dan Candida albicans walaupun dengan zona hambat yang dikategorikan sedang. Kata Kunci : Ianthella basta, antimikroba, Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa, Candida albicans.
