The effect of dietary soybean meal on growth, nutrient utilization, body composition and some serum biochemistry variables of two banded seabream, Diplodus vulgaris (Geoffroy Saint-Hilaire, 1817)

This study was performed to determine the optimum level of soybean meal diets for two banded seabream for growth performance, nutrient utilization, body composition and serum biochemistry. Two banded seabream were fed five experimental diets which were formulated replace fish meal by soybean meal at 0, 20, 30, 40 and 50%. Up to 40% of dietary fish meal was successfully replaced with no growth depression. Whole body composition of two banded seabream was not affected by soybean meal inclusion level. Total protein, triglyceride and total cholesterol of fish fed the SM50 diets were significantly lower compared to fish fed the soybean free diet. On the other hand, serum glucose level significantly increased as dietary soybean meal inclusion increased. Results showed that 40% fish meal can be replaced in diets for the two banded seabream by defatted soybean meal. Further studies to determine the inclusion level of soybean meal more than 40% with amino acid or enzyme supplementation are needed

Farklı BAP konsantrasyonlarının soya fasulyesinde (Glycine max L. Merrill) adventif sürgün rejenerasyonu üzerine etkileri

Bu çalışmada soya fasulyesinin (Glycine max L. Merrill) Agrova SA88 çeşidi kullanılarak, farklı BAP konsantrasyonlarının adventif sürgün rejenerasyonu üzerine etkileri araştırılmıştır. Uygulamalarda kullanılan fideler in vitro koşullarda çimlendirilmiştir. Çimlendirilen fidelerden alınan gövde ucu, boğum, yaprak, petiyol, kök, kotiledon ve hipokotil eksplantları Murashige ve Skoog (MS) ortamında farklı konsantrasyonlarda Benzil Amino Pürin (BAP) ile muamele edilmiştir. Eksplantlara uygulanan BAP’ın 2 ve 3 mg/l konsantrasyonlarında en iyi adventif sürgün rejenerasyonu gözlenmiştir. Adventif sürgünlerin köklendirilmesi için Naftelen Asetik Asit (NAA) ve İndol-3-bütirik asit (IBA) uygulanmış ve 2 mg/l IBA’ nın kök gelişimini uyarmada en etkili Bitki Büyüme Düzenleyicisi (BBD) olduğu saptanmıştır. Gövde gelişimi ve köklendirilmesi tamamlanmış sürgünler gelişimini devam ettirebilmeleri için BBD içermeyen MS ortamına aktarılmıştır. Olgunlaşan bitkiler daha sonra saksılara transfer edilerek sağlıklı fideler elde edilmiştir.Effects on Adventitious Shoot Regeneration of Different BAP Concentrations in Soybean (Glycine max L. Merrill) Micropropagation of soybean (Glycine max L. Merrill); strain Agrova SA88 was investigated Seeds were surface sterilized and grown in vitro. The shoot tip, nod, leaf, petiole, root, cotyledon and hypocotyl explants from seedlings were incubated in Murashige and Skoog (MS) medium with different concentrations of Benzyl Amino Purine (BAP). 2-3 mg/l BAP was found to be most influential on adventitious shoot regeneration in soybean among the applications, The grown stem on explants were separated and incubated in MS medium with the Plant Growth Regulators (PGR)s of Naphthalene acetic acid (NAA) and Indole-3-butyric acid (IBA) for root development. 2 mg/l IBA was found to be more suitable for root development. The regenerated seedling were transferred PGRs-free MS medium for seedling development and the healthy individuals were aclimatised in pots and mature plants were provided

First-line treatment of patients with HER2-positive metastatic gastric and gastroesophageal junction cancer

Fluoropyrimidine+cisplatin/oxaliplatin+trastuzumab therapy is recommended for the first-line treatment of HER2-positive metastatic gastric adenocarcinoma. However, there is no comprehensive study on which platinum-based treatment should be preferred. This study aimed to compare the treatment response and survival characteristics of patients with HER2-positive metastatic gastric or gastroesophageal junction (GEJ) cancer who received fluorouracil, oxaliplatin, and leucovorin (mFOLFOX)+trastuzumab or cisplatin and fluorouracil (CF)+trastuzumab as first-line therapy. It was a multicenter, retrospective study of the Turkish Oncology Group, which included 243 patients from 21 oncology centers. There were 113 patients in the mFOLFOX+trastuzumab arm and 130 patients in the CF+trastuzumab arm. The median age was 62 years in the mFOLFOX+trastuzumab arm and 61 years in the CF+trastuzumab arm (P = 0.495). 81.4% of patients in the mFOLFOX+trastuzumab arm and 83.1% in the CF+trastuzumab arm had gastric tumor localization (P = 0.735). The median progression-free survival (PFS) was significantly higher in the mFOLFOX+trastuzumab arm (9.4 months vs. 7.3 months, P = 0.024). The median overall survival (OS) was similar in both groups (18.4 months vs. 15.1 months, P = 0.640). Maintenance trastuzumab was continued after chemotherapy in 101 patients. In this subgroup, the median OS was 23.3 months and the median PFS was 13.3 months. In conclusion, mFOLFOX+trastuzumab is similar to CF+trastuzumab in terms of the median OS, but it is more effective in terms of the median PFS in the first-line treatment of HER2-positive metastatic gastric and GEJ cancer. The choice of treatment should be made by considering the prominent toxicity findings of the chemotherapy regimens

FIRE PERFORMANCE OF LVL PANELS TREATED WITH FIRE RETARDANT CHEMICALS

In this study we evaluated the combustion properties of laminated veneer lumber (LVL) panels treated with various fire retardant chemicals. Commercially manufactured rotary-cut beech wood (Fagus orientalis L.) veneers were treated with a borax-boric acid mixture, monoammonium phosphate or diammonium phosphate. Based on our results the lowest combustion temperatures were observed in panels treated with diammonium phosphate (220 degrees C), while the highest combustion temperatures were observed in panels treated with a borax-boric acid mixture (420 degrees C). Chemically treated panels experienced less mass loss than untreated panels. Chemically treated panels could be used safely in building construction due to their improved fire performance

INVESTIGATION OF ENERGY SAVING PERFORMANCE AND OTHER RELATED PARAMETERS OF A DAYLIGHTING SCENARIO FOR AN INDUSTRIAL BUILDING

Field measurement method is used in this paper to analyze the energy saving potential of an industrial building. A daylight responsive automated lighting control system application is implemented and the energy consumption of the building is observed for a year. Daylight trespass enabled by using two holes at the roof of the building which have spherical lenses. In conclusion energy savings of the building is related to the sunshine duration parameter
