This study aimed to determine the efficacy of red pine and larch pine needles powder at different doses on productive performance, egg quality, hatching parameters, total fatty acid and cholesterol levels of laying quails. A total of 126 (84 ♀ and 42 ♂) 20-week-old laying quail were randomly distributed into seven experimental diets with three replicates of six (four female and two male) birds per cage. The groups were fed a basal diet (CON group), a basal diet with red pine needle powder (RPNP group) (1.5%, 3% and 4.5%), or a basal diet with larch pine needle powder (LPNP group) (1.5%, 3% and 4.5%) for 9 weeks. The results showed that the additives which were added into the ration did not affect feed intake and feed conversion ratio among the performance parameters compared to the control group (p > 0.05). Egg production increased by 13%-14% in RPNP 1.5% and LPNP 4.5% groups compared to the control group (p < 0.05). Egg weight increased by 4.04% only at the RPNP 4.5% dose (p < 0.05). However, egg weight decreased by 3.68%, 2.88% and 5.75% in RPNP 3% and LPNP 3% and 4.5% doses, respectively (p < 0.05). The highest increase in egg mass compared to the control was 13.61% in the RPNP 1.5% dose (p < 0.05). Egg shape index increased by 8.18% in the RPNP 1.5% group and 11.11% in the LPNP 3% group (p < 0.05). Haugh units increased by 1.87% and 1.77% in RPNP 1.5% and LPNP 4.5% doses, respectively (p < 0.05). The amount of broken eggs increased in the LPNP 1.5% (2.86%) and LPNP 3% (3.65%) doses relative to the control group (0.40%) (p < 0.05). Egg yolk decreased by 7.2%-17.6% in RPNP 1.5% and 3% groups and LPNP 3% and 4.5% doses (p < 0.05). Egg yolk diameter decreased by 3.21%-6.56% in RPNP 1.5% and 3% groups and LPNP 4.5% doses (p < 0.05). Yolk index decreased by an average of 5.5%-7% in RPNP 1.5% and 4.5% doses and LPNP 4.5% doses (p < 0.05). Pine needle supplementation increased total monounsaturated fatty acids in egg yolks by 6% compared to the control group, while cholesterol levels decreased by 7.73% compared to the control (p < 0.05). On the other hand, pine needle addition had no effect on incubation parameters (p > 0.05). Our results clearly indicated that the 1.5% red pine needles powder could be used as an additive to increase the egg production, egg mass and Haugh units in laying quails., (© 2025 Wiley‐VCH GmbH.

Nutrient concentrations, enzyme activities, viable probiotic counts and organic acid levels of fermented barley (FB) produced by solid state fermentation (SSF) and of its unfermented counterpart (unfermented barley (UFB)) were determined by quantitative methods, and compared with the second derivate spectra analysis (SDSA) of their attenuated total reflectance-Fourier transform infrared measurements. Moreover, in order to test the nutritional value of FB and UFB feeds, 3-d old Japanese quails were fed FB or UFB at 400 g/kg diet for 4 weeks. Chemical analysis indicated that FB had significantly increased crude protein, ether extract and ash contents, associated with lowered fibre and sugar contents, as compared with UFB. IR spectra pattern of FB and UFB samples were similar, but their SDSA parameters, particularly peak areas, differed significantly. The differences between FB and UFB in peak areas were highly correlated with the differences between two feeds in lipid, protein, total fibre, starch and sugar contents (p < 0.05). Furthermore, SDSA analysis found new peak areas only available in FB samples, indicating fortification with new biomolecules due to the effect of SSF. Feeding the FB containing diet for 3 or 4 weeks enhanced growth performance significantly and increased the carcass yield of quails, indicating its nutritional benefits in young growing quails. The results indicated that the further analysis of IR spectra data revealed important information on the chemical and biological properties of feed materials, which are found to be highly correlated with the results of compositional analysis and their biological value in animal model.

A 17-year-old female patient with a history of surgery for primary femoral and metastatic lung osteosarcoma was admitted to our clinic with palpitations. Upon evaluation, a metastatic osteosarcoma in the left ventricle was diagnosed. Based on the collaborative decision of the oncology and cardiovascular surgery clinics, surgery was performed and the patient was discharged without any problems. According to the recommendation of the oncology clinic, chemotherapy was postponed for 6 months after surgery. Five months postoperatively, however, she had a recurrence with 2 tumors. Based on the collaborative decision, chemotherapy was initiated and in 2 months the size of the recurrent tumors had diminished. The patient is still under the care of the oncology and cardiovascular surgery clinics and continuing her chemotherapy regimen. Osteosarcomas have a high mortality. Metastatic tumors of the heart are not common. The location of the metastasis and the characteristics of the primary tumor determine the treatment modality. In some previously published reports, various treatment choices have been described. In the present case report, we present a rare case with metastatic cardiac osteosarcoma.

A 53-year-old female patient with coronary arterial disease who had been diagnosed with conventional coronary angiography was scheduled to undergo elective coronary artery bypass grafting surgery. Preoperative routine evaluations of the whole blood count revealed severe thrombocytopenia (6000/mm3). The patient received a consultation by the internal medicine clinic. With an initial diagnosis of pseudothrombocytopenia, the patient's operation was delayed, and she was referred to a hematology clinic for further diagnosis. The thrombocyte count in heparinized whole blood was in the normal range. A smear of a fresh, nonheparinized blood sample revealed thrombocytes in aggregations of 5 to 14, which confirmed the diagnosis. The patient underwent operation with cardiopulmonary bypass with normal heparinization, and no unexpected postoperative complications, including bleeding, occurred in the early postoperative period. She had an uneventful recovery and was discharged from the hospital on the seventh postoperative day. Later routine polyclinic control evaluations showed no complications. We think the possibility of pseudothrombocytopenia should be discussed with patients. With the correct diagnosis, such patients can be safely given the chance of operation with no more than the usual risks of coronary bypass surgery.

A 48-year-old hiatus hernia patient with a history of an occasional epigastric burning sensation for the last 10 years presented with a new onset of chest pain in addition to the persistence of his other symptoms. An apical left ventricular aneurism was found on 64-slice computed tomographic angiography. Coronary angiography confirmed the diagnosis. No coronary lesion was found and the apical region of the left ventricle was avascular. He was operated on under the suspected preoperative possible diagnoses of left ventricular apical aneurysm, a pseudoaneurysm, or a diverticulum. Macroscopically, a subepicardial whitish aneurysmal region with a weakened wall was seen at the apical part of the left ventricle. The size of the lesion was 3 x 3 cm. The aneurysm did not have an extracardiac neck. When the aneurysm site was opened, a sclerotic aneurysm wall and a narrow neck below the incised sac was found; and the neck was communicating with the left ventricular cavity. The aneurysm site was resected and closed with a linear closure technique by using pledget-supported sutures. The termination of cardiopulmonary bypass was uneventful. The patient left the intensive care unit on the first postoperative day and was discharged from hospital on the 4th postoperative day. A subepicardial left ventricular aneurysm should therefore also be considered in the differential diagnosis of atypical chest pain.

A 32-year-old female patient presented with dyspnea and palpitation, and transthoracic echocardiography revealed the presence of pericardial effusion. Pericardiosynthesis was performed for drainage. Because of the rapid accumulation of effusion and the presence of a right atrial mass on follow-up echocardiography, a computed tomography scan was done that revealed a right atrial defect and the presence of advanced pericardial effusion. The patient was prepared for an emergency operation. The mass on the right atrial wall was approached via a midsternal incision with cardiopulmonary bypass. The tumor filled the right atrial cavity, compressed vital structures, extended to the right ventricle, and had local metastases. As the tumor did not appear to be curable with surgery, a palliative approach was adopted. The right atrial free wall and tissues causing cardiac obstruction were totally removed, the tumor itself was partially excised, and local metastases were sampled. The resulting right atrial wall defect was closed with a Dacron patch. The operation ended uneventfully, and the clinical status and vital and hemodynamic findings of the patient returned to normal. The pathological diagnosis based on the samples obtained during the operation was angiosarcoma. The patient had an uneventful postoperative period and was then referred to an oncology center for clinical recovery. No findings of local recurrence or metastases were observed during the postoperative follow-up. The patient completed her combination therapy and currently is free of any clinical problems at her 13th postoperative month. We believe that advancements in radiotherapy and chemotherapy regimes combined with surgery (radical, if possible) for the treatment of cardiac angiosarcomas may provide better survival and quality-of-life results.

Background: To determine the differences in the operative findings between the two groups of patients who had undergone either minithoracotomy or conventional sternotomy., Methods: We compared 12 valve operations that were performed in our clinic with minithoracotomy (group I) between January 1997 and November 1999 with 13 valve operations that were performed with conventional median sternotomy (group II) in the same period in regard to preoperative, perioperative and postoperative variables, retrospectively. Preoperative variables were age, sex, bleeding time, clotting time, platelet count, and additional diseases like diabetes mellitus, hypertension, etc. Perioperative variables were extracorporeal circulation (ECC) time, cross-clamp (CC) time, and operation time. Postoperative variables were mechanical ventilation period, stay in the postoperative intensive care unit and hospital, mediastinal drainage amount, the amount of blood and blood products for transfusions, and costs. Group I consist of six mitral valve replacements (MVRs), three aortic valve replacements (AVRs), one aortic valve replacement combined with mitral valvuloplasty, and two tricuspid valve replacements (TVRs). Group II consist of nine MVRs and four AVRs., Results: Statistical results are given with mean standard error (SEM) deviations. There were significant differences between the two groups in respect to operation time (in group I, mean operation time was 328 +/- SEM 22 minutes in group II, 271 +/- SEM 14 minutes (p < 0.04)); mediastinal drainage (in group I, mean drainage time was 283 +/- SEM 57 cc/m2, in group II, 490 +/- SEM 74 cc/m2 (p < 0.04)); and amounts of transfused blood and blood products (in group I, mean transfused blood products amount was 375 +/- SEM 115 cc/m2, in group II, 874 +/- SEM 184 cc/m2 (p < 0.03))., Conclusion: The operation times are apparently longer in the minithoracotomy group. On the other hand, less mediastinal drainage occurred and less blood and blood products transfusion needs were determined to exist in the minithoracotomy group.

A noninvasive approach to determine viable but asynergic myocardium will be clinically significant in identifying patients with coronary artery disease and severe left ventricular dysfunction who will benefit most from coronary bypass surgery. Accordingly, 12 patients (mean ejection fraction 0.32 +/- 0.03) underwent quantitative planar stress-redistribution-reinjection thallium scintigraphy and radionuclide ventriculography before and 8 weeks after revascularization for viability and segmental and global left ventricular function assessment, respectively. Reinjection scan showed new fill-in in 63% of segments without redistribution. Postoperative improvement in perfusion and function of asynergic segments were significantly better in viable compared to nonviable segments (P < 0.001, P < 0.01, respectively) with a strong correlation between improvement in 201-T1 uptake and function (P < 0.001). When adequacy of revascularization was considered, the predictive value of a positive preoperative viability test for functional improvement was 83%. Finally, mean ejection fraction and global wall motion score increased significantly after revascularization for the group as a whole (0.32 +/- 0.03 to 0.44 +/- 0.04, P < 0.001 and 24.08 +/- 2.90 to 33.16 +/- 3.32, P < 0.001, respectively). Thus, preoperative quantitative planar stress-redistribution-reinjection thallium imaging detects viable but asynergic segments which improve function postoperatively and may be valuable in selection of patients with severe left ventricular dysfunction for revascularization.
