Authors: Tahapari Evi , Iswanto Bambang , Sularto Sularto 
Published: November 2016

Patin nasutus merupakan salah satu spesies patin Indonesia yang potensial untuk dikembangkan sebagai komoditas baru perikanan budidaya. Upaya pengembangan patin nasutus memerlukan informasi-informasi biologi-reproduksi berkaitan dengan kapasitas produksi massalnya. Penelitian ini bertujuan untuk mengetahui keragaan reproduksi patin nasutus. Hasil pengamatan perkembangan gonad menunjukkan bahwa oosit intraovarian patin nasutus dapat dibagi dalam lima tahap, yakni tahap 1 (kromatin nukleolar dan perinukleolar) dengan diameter oosit kurang dari 0,125 mm, tahap 2 (vesikula kuning telur dan alveoli korteks) dengan diameter oosit 0,125-0,500 mm, tahap 3 (granula kuning telur) dengan diameter oosit 0,700-1,850 mm, tahap 4 (migrasi nukleus dan hidrasi) dengan diameter oosit 1,250-1,900 mm dan tahap 5 (atresis) dengan diameter oosit 0,300-1,700 mm. Perkembangan oosit patin nasutus bersifat sinkronis grup, ditandai dengan adanya dominasi dua kelompok oosit intraovarian pada ikan dengan tingkat kematangan yang tertua, yakni kelompok oosit tertua (oosit tahap 3) yang akan segera dikeluarkan pada saat pemijahan dan kelompok oosit stok yang belum berkuning telur dan berukuran kecil (oosit tahap 1) yang merupakan telur cadangan untuk proses pemijahan berikutnya. Oosit tahap 3 merupakan tahap perkembangan oosit tertua yang dapat terjadi secara sempurna dan responsif terhadap induksi stimulasi hormonal. Tipe perkembangan testis patin nasutus bersifat asinkronis, ditandai dengan keberadaan berbagai tahap perkembangan sel-sel gamet jantan. Fekunditas relatif patin nasutus berkisar 26-67 butir telur per gram bobot induk, lebih tinggi daripada patin jambal, tetapi lebih rendah daripada patin siam. Derajat penetasan patin nasutus berkisar 44,16-79,05% dengan lama inkubasi 22-25 jam pada suhu inkubasi 29-30oC. Ukuran panjang total larva yang baru menetas berkisar 4,700-5,200 mm.

Authors: Lehmann Hendrik , Schneider Matthias , Moritz Andreas , Hassdenteufel Esther 
Published: November 2016

ZusammenfassungVergiftungen können zu lebensbedrohlichen Notfällen führen. Neben der allgemeinen Stabilisation des Patienten sollte eine Therapie eine schnellstmögliche Toxinelimination bewirken. Zunächst wird versucht, durch allgemeine Dekontaminationsmaßnahmen (gastrointestinal, dermal, okulär) die Giftaufnahme so gering wie möglich zu halten. Eine genauere Eingrenzung des Toxins bzw. seiner Eigenschaften kann bei der Auswahl spezifischerer Behandlungsansätze, wie beispielsweise Dialyse oder Gabe eines Antidots, Hilfestellung leisten. Die Therapie mit Lipidemulsionen zur raschen Elimination lipophiler Substanzen aus dem Körper hat in den letzten Jahren zunehmend an Bedeutung gewonnen. Sie kann das Allgemeinbefinden des Patienten schnell verbessern und ist mit wenig Nebenwirkungen verbunden.
The Status of Quality Assurance in Two Lebanese Universities
Authors: Al Chibani Wessam 
Published: November 2016

This study was set to assess and analyze the status of two private university quality measures such as the quality audit, control, and ranking in Lebanon. In addition, it was set to discuss and evaluate the programs given by these universities. Finally, it was set to synthesize and analyze different tools that could be applied on the quality services these universities have. The sample of this study is two private universities in Lebanon where interviews were conducted separately with 6 deans, 6 chairpersons, and 6 coordinators. In addition to the universities, plenty of information was taken directly from the Ministry of Education and Higher Education of the Republic of Lebanon.
Thus, qualitative data analyses were conducted. Main results showed that one of the main aims of both universities is to get new students registered and have better quality of education. They always take into consideration the quality audit, control, and ranking, which allow them to be ranked from the top universities in Lebanon. One University has been accredited in 2015, which makes it necessary to follow up with the quality control; the second university is still working on getting accredited.
The study concluded with recommendations addressed to private universities in Lebanon.
Performance of 15 tropical tree species recruited or transplanted on restoration settings
Authors: Guzmán-Luna Alejandra , Martínez-Garza Cristina 
Published: November 2016

Background. Minimal restoration intervention includes actions to stop disturbance so natural succession may take place whereas maximal intervention involves the establishment of plantings.
Questions. To evaluate the success of minimal versus maximal restoration intervention, the performance of recruits and transplants was assessed. To this end, performance of 15 native tree species was predicted using life-history, their origin (recruits or transplants) and 12 plant functional traits.
Study site and years of study. This study was carried out in pastures at Los Tuxtlas, Veracruz, Mexico in 5 years old restoration settings.
Methods. Pioneer and non-pioneer specie were planted in 16 30 × 30 m plots whereas natural recruitment was evaluated in plantings and at eight additional fenced plots.
Results. Overall 15 species recruited or planted, pioneers had higher performance than non-pioneer. Transplant shock in terms of survival and height growth rates was overcome after 5 years probably as a result of increases in diameter growth rates.
Conclusions. Tree species were divided in three groups to give recommendation for restoration: (1) Species in the Good recruiters group do not need to be transplanted; if seed sources are not close, we recommend direct seeding (i.e., Albizia purpusii , Cedrela odorata , Cecropia obstusifolia ). (2) Species in the Good transplants group show very low or nil recruitment; they should be transplanted (i.e., Ochroma pyramidale , Ficus yoponensis , Cojoba arborea ). (3) Species in the Poor transplants group should be transplanted but once a canopy has developed (i.e., Amphitecna tuxtlensis , Brosimum alicastrum , Bernoullia flammea ).
The Andean Forest Soil Seed Bank in Two Successional Stages in Northeastern Colombia
Authors: Gelviz-Gelvez Sandra Milena , Sánchez-Montaño Luis Roberto , Lopez-Toledo Leonel , Barragán Felipe 
Published: November 2016

Background: Soil seed banks play an important role in post-disturbance regeneration and succession of species from different successional stages.
Questions: 1) What is the most effective method for determining the composition and structure of the soil seed bank of Andean forests? 2) What is the composition and structure of soil seed banks in old-growth forest and shrubland sites in the Andean montane tropical forest of the North Santander region of Colombia?
Study site: Andean forest, Pamplona, Colombia
Methods: We surveyed the soil seed bank in two successional stages of Andean forest and examined its structure using two sampling methods: direct separation and germination.
Results: Soil seed bank density was higher (18-fold in old-growth forest and 666-fold in shrubland) with the direct separation method than with germination; however, under the germination method, we found four species that we did not detect through the direct separation method. Soil seed banks from shrublands were mainly dominated by species from disturbed areas (91 %), while those from the old-growth forest presented early, intermediate and late species; e.g., Miconia summa , Myrsine dependens and Solanum sp., respectively. In the old-growth forest (especially for late species), density increased with depth. This pattern was not observed in shrubland. Seeds obtained by using the direct separation method presented low (< 7 %) viability.
Conclusion: We consider the two methods to be complementary and recommend the use of both for a thorough characterization of soil seed banks from Andean forests. At different successional stages in the Colombian Andean forest, the soil seed bank may contain early, intermediate and late species, and it therefore plays an important role in the regeneration of this threatened ecosystem.
Differentiation and genetic diversity of Phaseolus lunatus wild populations from Chiapas, Mexico, and their genetic relationships with MI and MII groups
Authors: Ruiz-Gil Pedro Jesús , Chepe-Cruz Gabriel , Andueza-Noh Rubén Humberto , Ortiz-García Matilde Margarita , Martínez-Castillo Jaime 
Published: November 2016

Background . Understanding the genetic structure of wild relatives of domesticated species is crucial for its conservation and to elucidate the sites of crop domestication. Lima bean is one of the five domesticated Phaseolus species and Mexico is one of its centers of domestication. Recent studies showed the existence of two wild gene pools (MI and MII) of this species in Mexico and suggested that their genetic divergence occurred in southeast Mexico.
Question . Did MI and MII groups diverged around the Isthmus of Tehuantepec, Mexico?
Studied species . Lima bean: Neotropical plant species, herbaceous, with an annual/short life cycle and with autogamous tendency.
Study site and years of study . Seven wild populations were collected in 2012 in the State of Chiapas, México, area underrepresented in previous studies.
Methods . Genetic diversity and grouping patterns of collected populations and their relationship to MI and MII groups were analyzed at eight microsatellite loci.
Results. High genetic structure ( F ST: 0.42 to 0.96) and a high level of genetic diversity ( H E = 0.48) were found. The analyses, and presence of admixed populations in MI and MII, suggested that the genetic divergence of these groups is an ongoing process centered around the Isthmus of Tehuantepec.
Conclusions . Our results support the hypothesis that MI and MII groups diverged around the Isthmus of Tehuantepec; however, sampling should be increased both at population and genomic levels, to determine the precise organization of the genetic diversity of wild P. lunatus from Mexico
Pine seed removal in fragments of three temperate plant communities
Authors: Flores-Peredo Rafael , Sánchez-Velásquez Lázaro Rafael , Bolívar-Cimé Beatriz del Socorro 
Published: November 2016

Background: Foraging strategies may vary among guilds of granivores and impact the tree recruitment and biodiversity of plant communities.
Hypothesis : The hypotheses were: during the night in areas with tree cover rodents will be the main seed removers, insects in open areas at night, and birds in all types of plant communities during the daytime.
Studied species/Data description/Mathematical model: The seed removal by birds, rodents and insects was studied in a Mexican temperate forest. In order to detect differences in seed removal of Pinus patula , P. pseudostrobus , P. teocote and P. montezumae, a GLMM model with three way interaction (type of plant community, exclusion treatment and period) was carried out for each pine seed species where random variables were the variation among sites and months.
Study site and years of study: This study was carried out in a Mexican temperate forest during February 2006 and January 2007.
Methods : Through exclusion treatments we evaluated the seed removal of four pine species in three plant communities with two replicates (1 ha approximately) and two periods.
Results : The three-way interaction was significant for all pine species ( P < 0.001) (GLMM processes). The variance was greater among sites than between months. The main seed removers for all pine seed species, were: At night insects for subalpine grassland; during the daytime birds for all plant communities, and at night the rodents in pine forest, oak-alder forest and finally in the subalpine grassland.
Conclusions : The rodents were the main seeds removers in areas with tree cover during the night, the insects in open areas at night, and birds in all plant communities during the daytime.

Trilhos que se bifurcam: formação e inserção entre Candido e Rama
Authors: Toro Eduardo Andrés Mejía 
Published: November 2016

O dialogo intelectual entre Antonio Candido e Ángel Rama tem sido considerado em múltiplas ocasiões como metáfora da continuidade do processo de integração do pensamento latino-americano. Este artigo pretende contestar a pretensa sincronia de paradigmas desses autores à luz da contraposição proposta por Silviano Santiago entre o paradigma da formação e o paradigma da inserção. Busca-se questionar a plasticidade do sistema literário, que, sob um mesmo teor, pode ser compreendido tanto num viés nacional quanto num prisma continental.

Authors: Singh‐Kandola Kiran , Tailor Neeta , Phillips Jessica , Collis Rachel 
Published: November 2016

SummaryWe present a rare, and often mis‐diagnosed, case of an isolated cortical venous thrombosis. The consequences of this are potentially severe, and its non‐specific presentation requires a high degree of suspicion.A 26‐year‐old female had had an uncomplicated lower segment caesarean section at term. A combined spinal epidural anaesthetic technique was used and there were no immediate postpartum issues. The patient was readmitted ten days later with a three day history of severe headache and photophobia. CT scan of the brain was normal. On day two she suffered a seizure with residual right sided weakness. MRI scan demonstrated sub‐acute haemorrhage into the subdural space of the left posterior portion of the frontal lobe. A cerebral angiogram revealed delayed filling of the cortical veins of the left parietal lobe. Following treatment there were no neurological sequelae.
PERKEMBANGAN PENELITIAN KLON KARET UNGGUL IRR SERI 100 SEBAGAI PENGHASIL LATEKS DAN KAYU
Authors: Daslin Aidi 
Published: November 2016

Klon unggul merupakan salah satu komponen teknologi terpenting yang secara langsung berperan dalam meningkatkan potensi hasil tanaman. Sejalan dengan berkembangnya industri kayu karet, sasaran program pemuliaan tidak hanya menghasilkan klon unggul yang memiliki potensi hasil lateks tinggi tetapi juga produksi kayu yang tinggi. Penelitian untuk menghasilkan klon-klon karet unggul baru telah memperlihatkan kemajuan yang signifikan dalam hal peningkatan potensi produksi, pemendekan masa tanaman belum menghasilkan dan peningkatan potensi biomassa kayu. Kegiatan pemuliaan karet sudah berjalan selama empat generasi (1910-2010) dan pada generasi keempat telah menghasilkan beberapa klon unggul dengan produktivitas yang tinggi sebagai penghasil lateks dan kayu, yang terdiri atas klon IRR 107, IRR 112, IRR 118 dan IRR 119. Pertumbuhan klon-klon ini cukup jagur, rata-rata pada umur empat tahun telah dapat dibuka sadap dibanding klon-klon konvensional (klon yang umum ditanam pada saat ini) mencapai lima sampai enam tahun. Potensi biomassa kayu pada saat peremajaan cukup tinggi, mencapai 300 m3/ha dibanding dengan klon-klon konvensional hanya 150-200 m3/ha. Produktivitas karet kering kumulatif per hektar selama sepuluh tahun sadap adalah 19,4 ton untuk klon IRR 107, 20,5 ton untuk IRR 112, 19,2 ton untuk IRR 118, 17,5 ton untuk IRR 119, lebih tinggi dibanding klon konvensional PB 260 (17,1 ton) dan BPM 24 (15,8 ton). Klon-klon ini harus dimanfaatkan sebesar-besarnya oleh perkebunan rakyat maupun perkebunan besar dalam program peremajaan karet. Untuk mendapatkan produktivitas yang optimal dan membangun industri perkebunan karet yang sehat dan berdaya saing tinggi, penanaman klon unggul lateks dan kayu harus dikembangkan dengan dukungan teknologi yang tepat.
Streptococcus mutans adhesion on nickel titanium (NiTi) and copper-NiTi archwires: A comparative prospective clinical study
Authors: Abraham Kirubaharan S. , Jagdish Nithya , Kailasam Vignesh , Padmanabhan Sridevi 
Published: November 2016

ABSTRACT

Objectives:
To compare the adhesion of Streptococcus mutans to nickel titanium (NiTi) and copper-NiTi (Cu-NiTi) archwires and to correlate the adhesion to surface characteristics (surface free energy and surface roughness) of these wires.

Materials and Methods:
A total of 16 patients undergoing orthodontic treatment with preadjusted edgewise appliances were included in the study. 0.016” and 0.016” × 0.022” NiTi and Cu-NiTi archwires in as-received condition and after 4 weeks of intraoral use were studied for S mutans adhesion using real-time polymerase chain reaction. Surface roughness and surface free energy were studied by three-dimensional surface profilometry and dynamic contact angle analysis, respectively.

Results:
S mutans adhesion was more in Cu-NiTi archwires. These wires exhibited rougher surface and higher surface free energy when compared to NiTi archwires.

Conclusions:
S mutans adhesion, surface roughness, and surface free energy were greater in Cu-NiTi than NiTi archwires. Surface roughness and surface free energy increased after 4 weeks of intraoral exposure for all of the archwires studied. A predominantly negative correlation was seen between the cycle threshold value of adherent bacteria and surface characteristics.
