Seasonal changes of invertebrate fauna associated with Cystoseira barbata facies of Southeastern Black Sea coast
This research was carried out to determine the invertebrate fauna associated with Cystoseira barbata facies distributed in the upper-infralittoral zone of the Southeastern Black Sea coasts and their bioecological features. The investigations were seasonally performed at depths of 0 to 3 m in 5 different stations chosen in the Southeastern Black Sea from July 2005 to May 2006. As a result of the study, a total of 6123 specimens belonging to 38 species and 4 taxonomic groups were identified. Arthropoda was the dominant group in terms of number of species (55.3% of the total of phylum) and number of individuals (83.9% of the number total individuals). With regard to frequency index, 14 species were defined as continious, 8 species of common and 16 species as rare. Idotea metallica is reported for the first time from the Black Sea coast of Turkey in the present study.Keywords: Seasonal changes, invertebrate fauna, Cystoseira barbata, Black Sea, Turke
The double outlet right ventricle with additional cardiac malformations: an anatomic and echocardiographic study
Double outlet right ventricle (DORV) is a complex group of abnormal ventriculoarterial
connections where both the aorta and pulmonary artery rise from the
right ventricle morphologically. It is a rare condition affecting 1–1.5% of patients
with congenital heart disease.
The patient’s cardiac measurements were taken by two-dimensional echocardiography.
The pathological findings of the defined case are illustrated in the figures.
A 20-year-old male patient with palpitations, tachypnea, and tiredness with
weak exercise capacity and back pain was diagnosed with heart murmur in
different degrees; slight cyanosis, cachexia, and developmental retardation were
found clinically. Echocardiography showed: DORV, perimembranous ventricular
septal defect, pulmonary stenosis, dilatated right ventricle, and dilatated
left atrium. However, the left ventricle was normal. In addition, the septum
interatriale filled the left atrium like an aneurysm.
DORV is an important and rare congenital cardiac malformation. This complex
condition may result in different clinical findings and require different therapeutic
approaches
Absence of the musculocutaneous nerve together with unusual innervation of the median nerve
During routine anatomical dissections, absence of the musculocutaneous nerve
was determined in a 58-year-old male cadaver. Moreover, the biceps brachii
and brachialis muscles were innervated by two separate branches which divided
from the median nerve instead of the musculocutaneous nerve. From a branch
that divides from the main trunk of the median nerve at nearly the middle of the
arm a motor branch again divided that innervated the brachialis muscle and
a sensory branch that conveyed the sense of the lateral part of the forearm.
Furthermore, it was found that the brachial artery divided into its terminal branches,
the radial and ulnar arteries. We believe that this rare variation of the median
nerve will shed light upon surgical procedures involving the median nerve

New records of two species of gnathiid isopods, Paragnathia formica (Hesse, 1864) and Gnathia maxillaris (Montagu, 1804) (isopoda, gnathiidae) from the black sea
During fieldwork on the southeastern Black Sea coast, in October 2009, two gnathiid isopods were found in their free-living stage, Paragnathia formica (Hesse, 1864) and Gnathia maxillaris (Montagu, 1804). These species are herein reported from the Black Sea for the first time.© Koninklijke Brill NV, Leiden, 2011
