The term ‘edge effect’ can be defined as an abrupt and local change in the abundance, diversity, composition etc. at the edge of any distinct, spatial patches (structure(s). It usually refers to forest/field, meadow/shrub and other ecotone environments. This effect in relation to breeding densities and success in birds has been the focus of considerable debate (Manolis et al. 2002). The edge of bird colony is expected to affect similarly on avian population (Krebs 1974). Although such studies can be very useful for management and conservation strategies, they are scarce in the Mediterranean.

We encountered variation in the formation of the median nerve in a 66-year-old male cadaver during dissection of the upper extremity of 20 adult cadavers. The dissections were made at the Department of Cellular Biology and Anatomy, Louisiana State University Medical Center. The median nerve was formed by fusion of four branches, three of them coming from the lateral cord and one from the medial cord. The normal radix from the lateral cord followed a very close oblique course over the axillary artery. The first unusual radix to the median nerve had an anastomoses from the musculocutaneous nerve to the median nerve in the proximal part of the left arm. The second unusual radix also came from the musculocutaneous nerve after it had pierced the coracobrachialis muscle and then joined with the median nerve. These kinds of variations are vulnerable to damage in radical neck dissection and other surgical operations of the axilla and upper arm. The communicating branch can be explained on the basis of its embryologic development and also ought to be distinguished from the other nerve variations in the upper extremity. The aim of this paper is to provide additional information for the classification of previously found communications between the musculocutaneous and median nerves.

A vessel connecting the axillary or brachial artery to one of the forearm arteries was found in a 65 year old male cadaver, during the gross anatomy dissection of the upper extremity of 20 adult cadavers at the Department of Cellular Biology and Anatomy, Louisiana State University Medical Center. The right radial artery originated from the brachial artery nearly at the usual level and was connected to the axillary or brachial artery by a long slender anastomotic artery (vasa aberrantia). The anastomotic artery coursed under the medial side of the biceps muscle between the median and musculocutaneous nerves, and gave off two muscular branches to the biceps muscle. The anastomotic artery coursed between the median and musculocutaneous nerves in the arm, it passed to the forearm under the bicipital aponeurosis and connected the main radial artery on the radial side of the forearm. The anastomotic artery can be explained on the basis of its embryologic development and also ought to be distinguished from the other common arterial variations in the upper extremity.

It is known that a different ramification pattern can occur as a function of the development of the arteries of the lower limb. During a routine dissection, a variation of the deep femoral artery was found passing in front of the femoral vein in the left lower limb of a 43-year-old male cadaver. This case is reported because of its rare occurrence in the literature. The variation is discussed on the basis of the possible embryological development of the lower limb arteries.

Today, several fruit species are used for different purposes in alternative medicine. Among those species, barberry species are commonly used in treatment of various diseases. Jeti-Oguz District of Issyk Kul located around Issyk Lake in North-east of Kyrgyzstan has a unique flora and wild Berberis sphaerocarpa Kar. et Kit. (spherical-fruited barberry) species have a great place in regional flora. The fruits, leaves and roots of these species are commonly used by local people as functional products in alternative medicine. The most significant parameter in this wild population is the morphological variation in fruits and leaves. In this study, pomological analyses were performed on ripened black fruits of 26 wild genotypes. Pomological analyses yielded the fruit weights as between 0.23 g (01-JO-006) and 0.61 g (01-JO-025); total soluble solids as between 16.67% (01-JO-014) and 18.73% (01-JO-010 and 01-JO-018). Fruit shapes of genotypes were identified as long, long-spherical, spherical and oblate spherical. Significant variations were observed in morphological characteristics of spherical-fruited barberry genotypes through pomological analyses and field observations.

Background: Studies evaluating the mean volumes of nasal cavity and concha are very rare. Since there is little date on the mentioned topic, we aimed to carry out the presented study to obtain a volumetric index showing the relation between the nasal cavity and concha. Material and methods: The volumes of the nasal cavity and concha were measured in 30 males and 30 females (18–40 years old) on computed tomography images using stereological methods. Results: The mean volumes of nasal cavity, concha nasalis media, and concha nasalis inferior were 5.95 ± 0.10 cm³, 0.56 ± 0.22 cm³, and 1.45 ± 0.68 cm³; 7.01 ± 0.18 cm³, 0.67 ± 0.31 cm³ and 1.59 ± 0.98 cm³ in females and males, respectively. There were statistically significant differences in the volume of the nasal cavity and concha nasalis media (p < 0.05) between males and females, except for concha nasalis inferior (p > 0.05). Conclusions: Our results could provide volumetric indexes for the nasal cavity and concha, which could help the physician to manage surgical procedures related to the nasal cavity and concha.

Traditionally, Morus rubra L. (Moraceae) (red mulberry) and Cornus mas L. (Cornacea) (cornelian cherry) fruits are eaten fresh and are also used in marmalades, juices, jam, natural dyes in Turkey and are believed to have beneficial effects in case of multiple health issues such as antipyretic, diarrhea and intestinal parasites. However, the effects of M. rubra and C. mas on epilepsy has not been known. This study evaluates the effects of M. rubra and C. mas extracts on penicillin‑induced epileptiform activity. Sixty Wistar rats randomly divided into ten groups (n=6): control, sham, penicillin, penicillin+M. rubra extract (2.5, 5, 10, 20 mg/kg) and penicillin+C. mas extract (2.5, 5, 10 mg/kg). Epileptiform activity was induced by using penicillin (500 IU, i.c.) and electrocorticogram records (150 min) were obtained. Also, biochemical analysis in blood samples were evaluated. According to the electrocorticogram analysis, the effective dose was detected as 10 mg/kg for both C. mas and M. rubra. This dose decreased the spike frequencies of convulsions while amplitude wasn’t changed by both substances. In erythrocyte studies, there were significant differences regarding nitric oxide in the control, sham and penicillin groups. There were significant differences regarding malondialdehyde in all groups. In the plasma, there were significant differences among groups regarding xanthine oxidase in the penicillin‑C. mas and penicillin‑M. rubra groups. There were differences regarding malondialdehyde in the penicillin‑C. mas and M. rubra‑C. mas groups. Both extracts reduced the frequency of epileptiform activity. After administration of the extracts malondialdehyde levels decreased also in both erythrocytes and plasma.
