Investigation of formation variation of portal vein with multidetector computed tomography

Background: To determine the types, frequency and clinical implications of formation of variations of portal vein with routine abdominal multi detector CT.Methods: MDCT images of 265 patients without any pathology were evaluated. Types and frequencies of formation variations of portal vein were determined.Results: Portail vein formation variations were observed in 186 (70.15%) of our study population. Normal portal vein was detected in 79 (29.8%) images. These variations were classified according to frequency. Normal anatomic structure was determined as type 1. Type 1 was observed in 79 (29.8%) images. As type 2 variation, left gastric vein flows into splenic vein instead of portal vein (60.75%). The type 3 of portal vein variation as uniting of superior mesenteric vein, inferior mesenteric vein and splenic vein at the same trunk to form portal vein was determined 9.43%.Conclusions: This study, which was performed to determine the anatomical variations of portail vein, makes the type 2 variation rate higher than the other studies. This information is different from the classical anatomy information. In addition, we are able to make the radiologists and surgeons highly capable of both recognition and functionality of the results

An assessment of nasal and orbital parameters in human fetuses

Background: Nasal bone aplasia and hypoplasia have been reported on fetuses with aneuploidy. Trisomy 21 is one of the most common chromosomal abnormality detected in new-borns. The purpose of our study is to obtain data of some face parameters in Turkish fetal population and to contribute creation of reference ranges that may be used for prenatal diagnosis.Methods: This study was performed in 66 spontaneously aborted fetuses (47 second trimester and 19 third trimester) (28 male and 38 female) with no detectable external pathology or anomalies. Measurements were designed as nasal bone length (NBL), nose length (NL), nose width (NW), nostril width (NsW),                intraocular distance (IOD), innercanthal distance (ICD), outercanthal distance (OCD), orbital diameter (OD), biparietal diameter (BPD).Results: In comparison between genders, ICD and BPD averages were found significantly higher in male fetuses than female fetuses (P<0.05). There was not any statistically significant difference between averages of the values on the right and left. The difference between second and the third trimester was significant in terms of all parameters (P<0.05). A strong correlation was detected between gestational age and our parameters.Conclusions: Present study has contributed to create reference ranges of Turkish community. When importance of early diagnosis is considered, we believe that this data will be useful for clinicians

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

Odnos ızmeđu boje bazena ı prırasta mlađı evropskog brancına (dıcentrarchus labrax)

Dizajn sistema za gajenje riba je veoma bitan za održivu i visoko profitabilnu proizvodnju u akvakulturi. Različitim vrstama riba potrebani su drugačije dizajnirani sistemi i veštačke sredine. Sistemi u zatvorenom prostoru su korisni za mrestilišta a tankovi su veštačka staništa za vrste gajene u tim sistemima. Prethodna istraživanja pokazuju da boja zida bazena utiče na nivo stresa kod riba (Rotlant et al., 2003) i parametre koji utiču na rast, a dobrobit riba može da bude ugrožena u stresnim uslovima (De Silva and Anderson 1994). Cilj ovog istraživanja je da ispita efekte koje različite boje zidova tankova imaju na prirast mlađi Evropskog brancina (Dicentrarchus labrax). 480 jedinki mlađi nasumice su raspoređene u 12 identičnih plastičnih tankova (40 jedinki po tanku). Zapremina svakog bazena iznosila je 40 litara. U triplikatu su korišćene četiri različite boje bazena (crvena, zelena, plava i svetlo žuta). Riba je hranjena komercijalnom hranomn za brancina 2 puta dnevno u period od 60 dana. Najveći prirast dostigla je riba gajena u crvenim bazenima, dok je riba gajena u žutim bazenima imala najmanji prirast. Prethodna istraživanja su pokazala da boja zida bazena utiče na prirast ribe u uslovima gajenja i da je različitim vrstama riba potrebna drugačija boja bazena da bi postigle najbolji prirast (Duray et al., 1996; Rotland et al., 2003; Imanpoor and Abdollahi, 2011). Rezultati pokazuju da boja bazena utiče na prirast riba u uslovima gajenja

Optimum Support Policy Component for the Development of Agricultural Production: Potato Producer

The present study aimed to determine the optimum policy component in an example of potato cultivation development based on the principle of the efficient use of scarce resources and maximizing the benefit of the producer. Agricultural support policies are commonly implemented by adopting a top-down approach. Regarding benefit maximization at the target group level, policies for agricultural products should be determined with a bottom-up approach. In this manner, in the present study, potato producers were determined to be the target group. Therefore, this study investigated the policy component that provides the highest benefit in line with the demands, expectations, and tendencies of the target group. The micro-data obtained from the potato-growing enterprises operating in provinces where potato cultivation was intensively carried out within the scope of Turkey constituted the research data. A face-to-face survey technique was used as the method for collecting the producer data. Simple descriptive statistics and one of the multivariate analysis techniques, conjoint analysis, were applied in the analysis and evaluation of the data. The optimum policy component setup was determined to be “Price and Payment Support: Above Market Price and 2 months term, Support Area and Amount: to production, 25.47 USD/da (23.04 EUR/da), time of announcement for the supports: pre-planting, and producer’s declaration: I do (I declare)” for the potato product. Accordingly, the necessity of a bottom-up approach in the planning and implementation of an agricultural support policy in Turkey is explained based on the results obtained. Therefore, it is considered necessary and beneficial to measure the level of producer benefits on the focus of applications that encourage potato production

The Efficacy of Surgical Treatment for Kienböck’s Disease with 4-5 ECA Pedicled Osseous Flap: A Retrospective Study

Aim: The aim of this retrospective study is to assess the effectiveness of surgical intervention for Kienböck's disease using 4-5 Extensor Compartmental Artery (4-5 ECA) pedicled osseous flap Method: Patients who underwent 4-5 ECA pedicled bone grafts for Kienböck's disease between January 2012 and January 2022 were included in the study. The patient files were analyzed retrospectively for age, gender, follow-up time, and complications. Disease staging was performed preoperatively using direct X-ray and MRI, and radiological improvement was evaluated postoperatively using radiography. The functional and clinical assessment was made by comparing preoperative and postoperative VAS, Q-Dash, and Mayo scores. Results: This study involved 23 patients (12 female and 11 male) with Kienböck's disease who underwent 4-5 ECA pedicled bone graft surgery. 13 cases were right-handed while 10 were left-handed. The mean age was 37.5 ± 12.5 years, and the mean follow-up time was 68 months. The mean preoperative Q-Dash score was 78.8 (± 9), the VAS score was 6.5 (±1.2, and the Mayo wrist score was 34.34 (±11.8). The mean postoperative Q-Dash score was 33.1( ±10), the VAS score was 2.4 (±1.7), and the Mayo wrist score was 73.9 (±14.5). The differences between preoperative and postoperative Q-DASH scores (p&lt;0.05), VAS scores (p&lt;0.05), and Mayo wrist scores (p&lt;0.05) were statistically significantly improved. Disease progression was observed in only two patients based on the Lichtman Classification in their follow-up radiographs. Conclusion: Our study demonstrates that the surgical treatment of Kienböck's disease using a 4-5 ECA pedicled osseous flap is a reliable and effective surgical treatment option

Post-intervention Status in Patients With Refractory Myasthenia Gravis Treated With Eculizumab During REGAIN and Its Open-Label Extension

OBJECTIVE: To evaluate whether eculizumab helps patients with anti-acetylcholine receptor-positive (AChR+) refractory generalized myasthenia gravis (gMG) achieve the Myasthenia Gravis Foundation of America (MGFA) post-intervention status of minimal manifestations (MM), we assessed patients' status throughout REGAIN (Safety and Efficacy of Eculizumab in AChR+ Refractory Generalized Myasthenia Gravis) and its open-label extension. METHODS: Patients who completed the REGAIN randomized controlled trial and continued into the open-label extension were included in this tertiary endpoint analysis. Patients were assessed for the MGFA post-intervention status of improved, unchanged, worse, MM, and pharmacologic remission at defined time points during REGAIN and through week 130 of the open-label study. RESULTS: A total of 117 patients completed REGAIN and continued into the open-label study (eculizumab/eculizumab: 56; placebo/eculizumab: 61). At week 26 of REGAIN, more eculizumab-treated patients than placebo-treated patients achieved a status of improved (60.7% vs 41.7%) or MM (25.0% vs 13.3%; common OR: 2.3; 95% CI: 1.1-4.5). After 130 weeks of eculizumab treatment, 88.0% of patients achieved improved status and 57.3% of patients achieved MM status. The safety profile of eculizumab was consistent with its known profile and no new safety signals were detected. CONCLUSION: Eculizumab led to rapid and sustained achievement of MM in patients with AChR+ refractory gMG. These findings support the use of eculizumab in this previously difficult-to-treat patient population. CLINICALTRIALSGOV IDENTIFIER: REGAIN, NCT01997229; REGAIN open-label extension, NCT02301624. CLASSIFICATION OF EVIDENCE: This study provides Class II evidence that, after 26 weeks of eculizumab treatment, 25.0% of adults with AChR+ refractory gMG achieved MM, compared with 13.3% who received placebo
