The population trend of the red-backed shrike, Lanius collurio, is declining in its range. We studied the breeding biology of this species in the 2011 and 2012 breeding seasons in the north of Turkey. Our study site was an area of approximately 650 ha in the Kızılırmak Delta. Population density was 2.4 breeding pairs (bp)/10 ha and 2.7 bp/10 ha in 2011 and 2012, respectively. Blackberry bushes were used most frequently as nest sites (66%). The mean height of the nests from the ground was 125 ± 39 cm. The mean height of nest plants was 224 cm ± 76 cm. Nest height and nest plant height were positively correlated. We present an inequality of breeding parameters in the two successive breeding seasons. In 2011, the red-backed shrikes arrived at their breeding sites later, began to breed later, laid smaller clutches, and were less productive than in 2012. The main factor of the nest failures was nest predation in the study area. We detected normal second broods (six pairs) and it seems that this case was not exceptional. The Kızılırmak Delta is an important breeding area of the red-backed shrike population and more comprehensive studies are required.

“…Nasal polyposis (NP) is a chronic inflammatory disease of the mucosa lining the nasal cavities and paranasal sinuses. 1,2 Its prevalence is 1% to4% in the general population, and it leads to complications such as nasal obstruction and rhinorrhea. 3,4 Although it is a well-known and easily diagnosed pathologic condition, its etiopathogenesis still requires discussion.…”

“…6,7,8 Additionally, studies have shown that the immune system and oxidative stress play important roles in the formation and development of NP. 1,9,10 Many studies have been conducted in a search for treatments for NP, and many antioxidant and anti-inflammatory agents have been investigated as potential treatments for this disease.…”

5-HT7 receptorsare over-expressed in patients with nasal polyps

Nasal polyposis (NP) is an inflammatory disease of the paranasal sinuses and nasal cavity. The primary purpose of our study is to determine the expression of 5-HT7 receptors both in nasal polyps and in healthy tissue in the nasal cavity. The subsequent aim is to compare the expression of 5-HT7 receptors in patients with NP and in inferior turbinate tissue (control).The study included 60 participants (40 with NP and 20 controls) aged 35 to 62 years. Nasal polyp samples were collected from all patients and relative 5-HT7 receptor expression analyses were performed. RT-PCR analysis of nasal polyps and control tissue identified 5-HT7 receptor expression in the nasal cavities of controls. This expression was approximately 67 times higher in nasal polyp tissue than in healthy tissue. Our study identifies the expression of 5-HT7 receptors in the nasal cavity for the first time. It is also the first demonstration of increased 5-HT7 receptor expression in tissue from nasal polyps, which occur in the paranasal sinuses and nasal cavity.

“…There are no any etiological factors that may explain the pathogenesis of NPs but currently inflammation continues to be the major factor [2]. Many studies have pointed out that histopathologic abnormities of NP were closely related to the infiltration of inflammatory cells [3][4][5].…”
