rectus sheath hematoma usually occurs unilateral but rare cases of bilateral hematoma have been reported. herein we report the first case of spontaneous bilateral rectus sheath hematoma in the kidney transplanted patient.

Rhythmic behaviors vary across individuals. We investigated the sources of this output variability across a motor system, from the central pattern generator (CPG) to the motor plant. In the bilaterally symmetric leech heartbeat system, the CPG orchestrates two coordinations in the bilateral hearts with different intersegmental phase relations (Δϕ) and periodic side-to-side switches. Population ...

Bilateral cochlear implant (BiCI) users have shown variability in interaural time difference (ITD) sensitivity at different places along the cochlea. This paper investigates perception of multi-electrode binaural stimulation to determine if auditory object formation (AOF) and lateralization are affected by variability in ITD sensitivity when a complex sound is encoded with multi-channel process...

Uncertainty is a ubiquitous feature of our daily lives. Although previous studies have identified a number of neural and peripheral physiological changes associated with uncertainty, there are limited data on the causal mechanisms underlying these responses in humans. In this study, we address this empirical gap through a novel application of fMRI in neurosurgical patients with focal, bilateral...

The aims in the present study were to assess reliability for two unilateral and bilateral field-based hamstring assessments compare magnitude, direction agreement of inter-limb asymmetry between tests sessions. Twenty-nine female soccer players (age: 21.1 ± 4.5 years; height: 169.7 5.8 cm; body mass: 66.2 6.4 kg) performed three repetitions per leg isometric 30° 90° knee flexion (KF) tasks, tot...

splenogonadal fusion is a rare entity with approximately 150 reported cases until the year 2005. the entity is a rare congenital anomaly in which there is fusion of splenic and gonadal anlagen or mesonephric derivatives. splenogonadal fusion has two continuous and discontinuous types. about ten cases have been reported to be associated with bilateral cryptorchidism in literature. very few cases...

background: neuroectodermal tumors (pnet) are malignant small cells neoplasm mainly occurring in children but can occur at any age. extensive bleeding into the pleural cavity is rare in children. hemothorax would be compatible with a variety of congenital anomalies including sequestration, patent ductus artreiosus, and pulmonary arteriovenous malformation. case report: a 2.5-years old girl who ...
