Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).Soybean is one of the legume crops and is the world's main source of protein and vegetable oil. Calcium is one of the essential elements needed by plants for growth and production. The purpose of this study was to determine the effect of calcium fertilizer on the growth and production of soybeans. This research was carried out from November 2020 to February 2021. The method in this study was a non-factorial randomized block design (RAK) with 4 types of calcium fertilizer treatments: 0 g/polybag (C0), 0.375 g/polybag (C1), 0.525 g/polybag (C2) and 0.865 g/polybag (C3). The results showed that calcium fertilizer had an effect on the number of pods, weight of pods, weight of filled pods, and weight of seeds. The calcium fertilizer treatment that gave the best results on the growth and production of soybeans was found in the C2 treatment at a dose of 0.525 g

Wild bonobos host geographically restricted malaria parasites including a putative new <i>Laverania</i> species

Malaria parasites, though widespread among wild chimpanzees and gorillas, have not been detected in bonobos. Here, we show that wild-living bonobos are endemically Plasmodium infected in the eastern-most part of their range. Testing 1556 faecal samples from 11 field sites, we identify high prevalence Laverania infections in the Tshuapa-Lomami-Lualaba (TL2) area, but not at other locations across the Congo. TL2 bonobos harbour P. gaboni, formerly only found in chimpanzees, as well as a potential new species, Plasmodium lomamiensis sp. nov. Rare co-infections with non-Laverania parasites were also observed. Phylogenetic relationships among Laverania species are consistent with co-divergence with their gorilla, chimpanzee and bonobo hosts, suggesting a timescale for their evolution. The absence of Plasmodium from most field sites could not be explained by parasite seasonality, nor by bonobo population structure, diet or gut microbiota. Thus, the geographic restriction of bonobo Plasmodium reflects still unidentified factors that likely influence parasite transmission

Half-molar sodium-lactate solution has a beneficial effect in patients after coronary artery bypass grafting.

International audienceOBJECTIVE: To compare two solutions for fluid resuscitation in post-coronary artery bypass grafting (CABG) surgery patients: Ringer's lactate (RL) versus a new solution containing half-molar sodium-lactate (HL). DESIGN: Prospective randomized open label study. SETTING: The first 12 h post-CABG surgery in an intensive care unit (ICU). PATIENTS: There were 230 patients enrolled in the study: 208 were analyzed, with 109 from the HL group and 99 from the RL group. INTERVENTIONS: Patients received over the first 12 h post-CABG 10 ml kg BW(-1) HL solution in the HL group versus 30 ml kg BW(-1) of RL solution in the RL group. MEASUREMENTS AND RESULTS: Hemodynamic status, body fluid balance and inotrope utilization were compared in the two groups. Post-operative cardiac index increase was significantly higher in HL than in RL (P = 0.02), while mean arterial pressure and other hemodynamic parameters were comparable together with urinary output, indicating similar tissue perfusion in both the groups despite a much lower fluid infusion in the HL group. Therefore, a significant negative fluid balance was achieved in the HL but not in the RL group (-790 +/- 71 vs. +43 +/- 115 mL 12 h(-1), P < 0.0001 for HL and RL, respectively). None of the enrolled patients exhibited side effects related to the treatment. CONCLUSION: Half-molar lactate solution is effective for fluid resuscitation in post-CABG patients. Compared to Ringer's Lactate, its use results in a significantly higher cardiac index with less volume being infused, resulting in a very negative post-operative body fluid balance
