Early phases of different types of isolated neutron star

Two Galactic isolated strong X-ray pulsars seem to be in the densest environments compared to other types of Galactic pulsar. X-ray pulsar J1846-0258 can be in an early phase of anomalous X-ray pulsars and soft gamma repeaters if its average braking index is ~1.8-2.0. X-ray pulsar J1811-1925 must have a very large average braking index (n~11) if this pulsar was formed by SN 386AD. This X-ray pulsar can be in an early phase of evolution of the radio pulsars located in the region P~50-150 ms and \.{P}~10$^{-14}-10^{-16}$ s/s of the P-\.{P} diagram. X-ray/radio pulsar J0540-69 seems to be evolving in the direction to the dim isolated thermal neutron star region on the P-\.{P} diagram. Possible progenitors of different types of neutron star are also discussed.Comment: to appear in the International Journal of Modern Physics

The Investigation of Prevalence of Enterobius vermicularis (L.1758) in Primary School Age Children and Its Relation to Various Symptoms İlköğretim Çağı Çocuklarında Enterobius vermicularis (L.1758) Yaygınlığı ve Çeşitli Semptomlar ile İlişkisinin Araştırılması

Enhancement of energy efficiency and introduction of newer and more efficient space and water heating technologies in the UK domestic sector are essential if the UK is to achieve its ambitious target for 2050 of reducing greenhouse gas (GHG) emissions to less than 80% of 1990 levels. The UK domestic sector currently relies heavily on conventional boilers for space and water heating even though electric or gas engine driven vapour compression heat pumps can provide heating and cooling with more than double the efficiency of conventional boilers. UK government has recently introduced laws and policies that are designed to accelerate the uptake of renewable heating technologies by domestic consumers rather than relying solely on market forces. To date despite their excellent performance heat pumps are not the primary choice of the general UK domestic consumer. Factors that may influence this behaviour have been analysed and are discussed here. (C) 2009 Elsevier Ltd. All rights reserved

İlköğretim Çağı Çocuklarında Enterobius vermicularis (L.1758) Yaygınlığı ve Çeşitli Semptomlar ile İlişkisinin Araştırılması

Objective: In this study, we aimed to determine the prevalence of Enterobius vermicularis (E. vermicularis) using anal tape technique in four different primary schools in the town of Kayseri.Methods: For this purpose, cellophane-tape samples were collected from a total of 438 students. Of all the students, 229 (52.2%) are female and 209 (47.7%) are male. In this study, the relationship between E. vermicularis and the parameters such as school, gender, residential structure, bathroom, water source, parents' monthly income, the number of rooms and members in the house and some symptoms such as anal itching, nasal itching, allergies, irritability, headaches and dizziness, night fears, dental grinding at night, abdominal pain, diarrhea, loss of appetite and weight loss were investigated.Results: E. vermicularis was determined in 44 of the 438 students (which is 10.4%). There were statistically significant relation between E. vermicularis and parameters such as residential structure, the number of rooms in the house, dental grinding at night, abdominal pain, parents' level of education. There was also statistically significant relation between E. vermicularis and socio-echonomical situation of primary schools.Conclusion: We believe that carrying out periodic screening in schools in which especially low-income and parasite-infected children should be treated, informed about prevention and control methods.Amaç: Bu çalışmada, Kayseri merkezde bulunan dört farklı ilköğretim okulunda selofan-bant tekniği kullanılarak Enterobius vermicularis (E. vermicularis) yaygınlığının belirlenmesi amaçlanmıştır.Yöntemler: Bu amaçla 209 (%47,7)'u erkek, 229 (%52,2)'u kız toplam 438 öğrenciden selofan-bant örneği alınmıştır. Çalışmada; okul, cinsiyet, konut yapısı, banyo, su kaynağı, velilerin aylık geliri, evdeki oda sayısı, kişi sayısı gibi parametreler ve anal kaşıntı, burun kaşıntısı, vücutta alerji, sinirlilik, baş ağrısı ve baş dönmesi, gece korkuları, gece diş gıcırdatması, karın ağrısı, ishal, iştahsızlık ve kilo kaybı gibi semptomlar ile E. vermicularis görülmesi arasında ilişki araştırılmıştır.Bulgular: İncelenen örneklerden 44 (%10,4)'ünde parazit saptanmıştır. Sosyo-ekonomik özellikleri dikkate alınınca okul ile parazit görülmesi arasında anlamlı bir ilişkinin olduğu saptanırken; konut yapısı, evdeki oda sayısı, gece diş gıcırdatması, karın ağrısı, anne-baba öğrenim düzeyi ile parazit görülmesi arasındaki ilişki istatistiksel açıdan anlamlı bulunmuştur.Sonuç: Okullarda, özelliklede gelir düzeyi düşük olanlarda, belirli aralıklarla taramalar yapılması ve paraziter enfeksiyonlu çocukların tedavi edilerek korunma kontrol yöntemleri hakkında bilgilendirilmesi gerektiği kanaatindeyi

The impact of dissection of station 9 on survival and the necessity of pulmonary ligament division during upper lobectomy for lung cancer

Background We conducted this study to investigate the need for dissection of station 9 lymph nodes during upper lobectomy for non-small-cell lung cancer (NSCLC) and to find out the operative results of inferior pulmonary ligament division. Methods A total of 840 patients who underwent upper lobectomy for NSCLC between January 2007 and June 2020 were evaluated retrospectively. The patients were separated into two groups - those having undergone lymph node dissection of station 9 and inferior pulmonary ligament dissection (Group I) and those who did not (Group II). In these groups, the prognostic value of station 9 lymph nodes and postoperative effects (drainage time, prolonged air leak, dead space and length of hospital stay) of ligament division or preservation were analyzed. Results The number of patients with station 9 lymph node metastasis was only one (0.1%) and that was multi-station pN2 disease. Station 9 lymph nodes were found in 675 (80.4%) patients, while 22 (2.6%) patients had no lymph nodes in the dissected material. In the other 143 (17%) patients, the inferior pulmonary ligament and station 9 were not dissected. While 5-year survival was 64.9% in 697 patients of Group I, it was 61.3% in 143 patients of Group II (p = 0.56). There was no statistically significant difference between the groups in postoperative effects of ligament division or preservation. Conclusions In upper lobectomies, status of station 9 does not have a significant impact on patients' survival and lymph node staging. Additionally, preservation or division of the inferior pulmonary ligament has no significant advantage or disadvantage

Conjunction of a Fungus Ball and a Pulmonary Tumourlet in a Bronchiectatic Cavity

Herein, we describe the case of a 67-year-old female patient who presented with cough and haemoptysis. Chest computed tomography revealed destruction of the left lower lobe and multiple fungus balls in a bronchiectatic cavity. A left lower lobectomy was performed via thoracotomy. Histopathological examination of the lung showed a concomitant aspergilloma and multiple tumourlets in the large bronchiectatic cavity. Pulmonary intracavitary aspergilloma and concomitant tumourlets are quite rare. Our report presents this interesting case that manifested with haemoptysis

Efficacy of Nebivolol on Flow-Mediated Dilation in Patients With Slow Coronary Flow

WOS: 000271304100001PubMed: 19809204Slow coronary flow (SCF) is the phenomenon of slow progression of angiographic contrast in the coronary arteries in the absence of stenosis in the epicardial vessels in some patients presenting with chest pain. There are no definite treatment modalities for patients with SCF. Our aim was to investigate the efficacy of nebivolol in patients with slow coronary flow by monitoring its effects on endothelial function and different markets of inflammation. Forty-two patients (16 females, 26 males mean age, 55 10) with slow coronary flow (SCF) were included in the study. After baseline assessment, the patients were administered nebivolol 5 mg once daily. After 12 weeks of nebivolol therapy, the biochemical and ultrasonographic examinations were repeated. Chest pain relief wits detected in 38 patients after treatment (90%). Systolic and diastolic blood pressure and high sensitive CRP were significantly decreased after nebivolol therapy. Among brachial artery dilation variables that reflect endothelial function, basal resistive index (RI), post-flow mediated dilation RI, and post-nitrate mediated dilation RI were significantly decreased after therapy. Nebivolol is effective at improving endothelial function in patients with SCF. It controls chest pain, decreases CRP, and has favorable effects on brachial artery dilation variables in patients with coronary slow flow. (Int Heart J 2009; 50: 545-553
