The effect of density on the cultivation of the native mangrove oyster Crassostrea tulipa (Lamarck, 1819)

In Brazil, the cultivation of Crassostrea tulipa (= C. gasar) is gaining in importance. However, little is known about the best conditions for farming. Therefore, this study aimed to evaluate the effect of oyster density (50, 100, 200, and 400 mL of seeds/0.15 m2; 100, 200, 300, and 400 ind/0.10 m2 (basket area) and 30, 60, 120, and 180 ind/0.13 m2 (lantern floor area) in nursey, juvenile and adult phase, respectively) on the growth and survival of C. tulipa in farm cultivation. In the nursery phase, the 50 mL density resulted in smaller oyster size, as expressed in height and height/length (H/L) ratio (1.31 ± 0.03 mm), compared to other densities, while the length and width was equal among densities. The animals' individual average weight and H/L ratio were negatively influenced by a density of 100 ind/0.10 m2 or bigger. However, animals grown at the density of 200 ind/0.10 m2 did not differ statistically in length or width from those grown with 100 ind/0.10 m2. A high survival rate (≥98%) was found in the nursery and juvenile phases.

From April 1984 to December 1987, the French Pediatric Oncology Society (SFOP) organized a randomized trial for advanced-stage B-cell lymphoma without CNS involvement to study the possibility of reducing the length of treatment to 4 months. After receiving the same three intensive six-drug induction courses based on high-dose fractionated cyclophosphamide, high-dose methotrexate (HD MTX), and cytarabine in continuous infusion, patients were evaluated for remission. Those who achieved complete remission (CR) were randomized between a long arm (five additional courses with two additional drugs; 16 weeks of treatment) and a short arm (two additional courses; 5 weeks). For patients in partial remission (PR), intensification of treatment was indicated. Two hundred sixteen patients were registered: 15 stage II nasopharyngeal and extensive facial tumors, 167 stage III, and 34 stage IV, 20 of the latter having more than 25% blast cells in bone marrow. The primary sites of involvement were abdomen in 172, head and neck in 30, thorax in two, and other sites in 12. One hundred sixty-seven patients are alive in first CR with a minimum follow-up of 18 months; four are lost to follow-up. Eight patients died from initial treatment failure, 14 died from toxicity or deaths unrelated to tumor or treatment, and 27 relapsed. The event-free survival (EFS), with a median follow-up of 38 months, is 78% (SE 3) for all the patients, 73% (SE 11) for the stage II patients, 80% (SE 3) for the stage III patients, and 68% (SE 8) for the stage IV and acute lymphoblastic leukemia (ALL) patients. One hundred sixty-six patients were randomized: 82 in the short arm and 84 in the long arm. EFS is, respectively, 89% and 87%. Statistical analysis confirms equivalence of both treatment arms with regard to EFS. Moreover, morbidity was lower in the short arm. This study confirms the high survival rate obtained in the previous LMB 0281 study without radiotherapy or debulking surgery and demonstrates the effectiveness of short treatment.

The purpose of this research was to investigate the use of drilled slanted holes filled with different substrates in the revegetation of rock slopes. Slanted holes were drilled on rock slopes using pneumatic drillers in an abandoned limestone quarry area. These holes were filled with twelve different substrates, treated with Trichoderma harzianum. One climbing plant of Ivy (Hedera rhombea), a native woody plant (Lespedeza cyrtobotrya), three native herbaceous plants (Dianthus barbatus, Siberian chrysanthemum and Aster koraiensis) and one exotic grass plant (Festuca arundinacea) were planted in each of the soils. Six months after planting, only Ivy, Festuca arundinacea, Lespedeza cyrtobotrya and Dianthus barbatus were still observed growing on the soils, while the other plant species had already died in all the 12 soil treatments. Leaf mold soil + 50% Trichoderma harzianum provide the best conditions for revegetation of Festuca arundinacea, as this plant had its highest mean height, high survival rate, with impressive growth rate on this soil. Lespedeza cyrtobotrya also had its most favorable growth on Leaf mold soil + 50% T. harzianum. Mixed soil + 100% T. harzianum provide the best conditions for revegetation of Ivy. Leaf mold soil + 100% T. harzianum provide the best condition for revegetation of Dianthus barbatus as it had its highest mean height, highest growth rate and high survival rate on this soil. Siberian chrysanthemum and Aster koraiensis had the worse results as all of the plants died within a short period of time after planting. Ivy had the highest mean height, followed by Festuca arundinacea. The planted Ivy and Festuca arundinacea now form the vegetation of the research site which together with the substrate is now providing habitat to some wildlife like some species of centipedes, earthworms, insects and wild plants. Less than one year after planting, F. arundinacea already produced flowers and seeds which would further increase the plant population after dispersal and germination. Drilling slanted holes on rock slopes is therefore a feasible method to be used for revegetation and restoration of degraded quarries.The revegetation of steep rock slopes of quarries is a very challenging activity. However, the method of drilling slanted holes on rock slopes is a feasible method to be used for restoration of degraded quarries. These holes could serve in soil deposition and water retention that will further enhance plant growth.Methods of improving seed germination as well as enhancing growth of plants are also imperative in revegetation success of such degraded landscapes. Different percentage mixtures of T. harzianum in different soils could enhance plant growth depending on the target plant species. Different substrates could thus be used in such revegetation process depending on the target plant species.Revegetation would provide habitat and improve landscape beauty and stability, thus it is important for successful restoration of rock slopes

The use of antibiotics for controlling of luminous vibriosis caused by Vibrio harveyi is restricted now, because it induces antibiotic-resistant bacteria and leave residue in shrimp’s body. An alternative solution that can be done to treat the disease is by using applications of probiotic, prebiotic, and synbiotic. The aim of this research was to examine the effect of probiotic, prebiotic, and synbiotic on the survival rate and growth of Pacific white shrimp against V. harveyi infection. Feed as a treatment was supplemented with probiotic 1%, prebiotic 2%, and probiotic 1%+prebiotic 2% (synbiotic). Shrimps feed without supplementation of probiotic and prebiotic was used as a control treatment. The shrimps were maintainedin the aquarium (60×30×35 cm3) with a density of 40 shrimps/40 L and an average weight of 0.4±0.1 g. After 30 days of feeding treatment, the shrimp was challenged by immersion method with V. harveyi solution containing 106 CFU/mL. The results showed that before challenge, synbiotic feed treated shrimp has a growth rate (5.89%), feed conversionrate (1.21), and a high survival rate (80%). After challenge, survival rate (83.33%) of shrimp fed diet supplemented with synbiotic was higher than prebiotic (51.67%) and positive control (31.67%).

Objectives: Venoarterial (VA) ECMO has emerged as a successful modality for bridging patients with critical cardiogenic shock to durable support. However, LV distention on ECMO impairs RV and lung recovery and can result in the need for a temporary RVAD. Additionally, patients on VA ECMO with organ dysfunction may require ongoing LV assistance for recovery prior to durable LVAD conversion. Placement of a large apical LV vent allows bedside conversion to LVAD and provides time for organ recovery prior to elective durable device implantation. Hypothesis: We hypothesized that LV venting on ECMO accelerates RV recovery, hastening conversion to LVAD. Methods: ECMO cases from January 2012 to April 2014 were reviewed following IRB approval. Sixteen patients met INTERMACS Category 1 criteria who were placed on VA ECMO for cardiogenic or post-cardiotomy shock. Eight patients had LV venting and eight had standard peripheral cannulation. Refractory pulmonary edema, CPR during cannulation, and severe LV distention were indications for LV venting. A 32 French malleable cannula was placed by limited anterolateral thoracotomy into the LV apex. Bedside LVAD conversion was performed by percutaneous decannulation of the venous line and removal of oxygenator from circuit. Results: Conversion to temporary LVAD was successful in all LV vent cases at a mean timepoint of 5.9 (±1.3) days after LV venting compared with 13.5 (±4.9) days in non-vented patients (p = 0.07). RVAD requirement was 25% in non-vented patients and 0% in vented patients. 30-day mortality was 25% for both groups. Conclusions: LV venting as an adjunct to VA ECMO facilitates RV recovery to enable early LVAD conversion at the bedside. It also provides organ recovery time and obviates the need for a temporary RVAD at the time of durable LVAD implantation. In conclusion, the LV apical venting technique allows staged recovery of critically ill patients in biventricular and multiple organ failure with a high survival rate.
