Primary tracheal adenocystic carcinoma and tracheal tumors during pregnancy

Cancer complicates approximately 0.1% of all pregnancies. Primary tracheal carcinoma is one of very rarely seen tumors and the rate of its being seen makes up approximately % 0.2 of all tumors of respiratory tract. The patient, 28 years old, who has 28-weeks-pregnant, was diagnosed with primary tracheal adenocystic carcinoma. Patient was made operation as thoracotomy and tracheal tumor was removed at the 28th week of pregnancy. Patient was delivered with sectio abdominale at the 39th week of pregnancy. Primary tracheal adenocystic carcinoma is very rarely seen tumors and it is the first tracheal ACC with pregnancy case in literature to have been detected and surgically treated during pregnancy. We discussed primary tracheal adenocystic carcinoma and tracheal tumors during pregnancy with literature

SESQUITERPENOID CAULERPENYNE LEVELS OF NEWLY IDENTIFIED CAULERPA TAXIFOLIA VAR. DISTICHOPHYLLA FROM THE ISKENDERUN BAY, TURKEY

WOS: 000384033100018The seasonal variations of caulerpenyne (CYN) levels, secondary metabolite of Caulerpa genus, were investigated in the fronds and stolons of Caulerpa taxifolia var. distichophylla recently present at three stations in the Gulf of Iskenderun, the Eastern Mediterranean Sea, including its relationships with various physicochemical parameters of the sea water. The CYN levels were highest in the spring, and decreased in autumn. Also, the CYN contents in the fronds were statistically higher than the stolons (p<0.05). The highest seasonal mean CYN content was determined in the fronds as 0.82 +/- 0.3 parts per thousand wet weight during summer season. However, there were no statistically significant differences in the CYN levels among sampling stations (p<0.05). It was also determined that the CYN levels had positive correlations with temperature and oPO4-P concentrations.Turkish Scientific and Technological Research Council of Turkey (TUBITAK)Turkiye Bilimsel ve Teknolojik Arastirma Kurumu (TUBITAK) [109Y284]The authors thank to Turkish Scientific and Technological Research Council of Turkey (TUBITAK) for financial support of the project 109Y284

Gallbladder perforation during elective laparoscopic cholecystectomy: Incidence, risk factors, and outcomes

OBJECTIVE: This study aimed to reveal the risk factors and outcomes of gallbladder perforation (GP) during laparoscopic cholecystectomy

Evidence of NW extension of the North Anatolian Fault Zone in the Marmara Sea: a new interpretation of the Marmara Sea (Izmit) earthquake on 17 August 1999

Active faults aligning in NW-SE direction and forming flower structures of strike-slip faults were observed in shallow seismic data from the shelf offshore of Avcilar in the northern Marmara Sea. By following the parallel drainage pattern and scarps, these faults were traced as NW-SE-directed lineaments in the morphology of the northern onshore sector of the Marmara Sea (eastern Thrace Peninsula). Right-lateral displacements in two watersheds of drainage and on the coast of the Marmara Sea and Black Sea are associated with these lineaments. This right-lateral displacement along the course of these faults suggests a new, active strike-slip fault zone located at the NW extension of the northern boundary fault of the Cinarcik Basin in the Marmara Sea. This new fault zone is interpreted as the NW extension of the northern branch of the North Anatolian Fault Zone (NAFZ), extending from the Cinarcik Basin of the Marmara Sea to the Black Sea coast of the Thrace Peninsula, and passing through Buyukcekmece and Kucukcekmece lagoons. These data suggest that the rupture of the 17 August 1999 earth-quake in the NAFZ may have extended through Avcilar. Indeed, Avcilar and Izmit, both located on the Marmara Sea coast along the rupture route, were strongly struck by the earthquake whereas the settlements between Avcilar and Izmit were much less affected. Therefore, this interpretation can explain the extraordinary damage in Avcilar, based on the newly discovered rupture of the NAFZ in the Marmara Sea. However, this suggestion needs to be confirmed by further seismological studies

Alçak Gerilim Ekspres Fider Uygulaması ile Sezonsal Yüklenme Farkları Yüksek Olan Dağıtım Transformatörlerin Boşta Kayıplarının Azaltılması

This study presents design, technical and economic feasibility analysis, and on-site implementation of low voltage express feeder (LVEF) implementation, which is aimed to reduce off-season technical losses of transformers located at the regions dominated by summerhouses along the Mediterranean Coast. Capacities of such transformers are generally determined considering peak demand during summer season. LVEF implementation is based on the concept of connecting close by transformer couples through an LVEF cable, which enables supply of total loads of the transformers by only one transformer during off seasons. It is important to avoid parallel operation of the transformers through the LVEF for safety concerns during implementation. An interlocking system is designed for this aim in the study. Voltage drop and technical loss analysis are performed with DIgSILENT PowerFactory (TM) software in the scope of technical analysis. The most prevailing transformer couples for the LVEF implementation are determined based on a priority criterion. A pilot LVEF implementation is performed satisfactorily at Karatas province. Toroslar Elektrik Dagitim A.$. is the distribution company responsible from the region which includes many summerhouses, and therefore suffers significant seasonal load deviation

Theoretical and Practical Aspects of Implementing a Low Voltage Express Feeder between Nearby Distribution Transformers to Reduce Annual Losses

Capacity of distribution transformers is usually determined based on peak demand forecasted along a planning period. Peak demand actualizes at different seasons depending on the load characteristics of the transformers. For example, transformers at coastal towns essentially experience peak demand during summer periods. Although such transformers are loaded up to their capacities at summer seasons, their loading level reduces drastically during the off-season periods. This study addresses technical losses of such transformers and presents a solution to reduce the total transformer losses by means of implementing a low voltage express feeder (LVEF) between transformers close by. Total load of two nearby transformers is supplied by only one of the transformers through the LVEF while the other transformer is de-energized during off-season period. Depending on the criteria addressed in this study, this approach enables a decrease in the annual total loss of the system. Study includes a pilot implementation on-site
