Chordoma located in the jugular foramen: Case report.

Rationale: Chordomas are rare malignant neoplasms arised from residual embryonic notochordal tissue, mostly located in the axial midline. Tumors along extra-axial locations in the head and neck are rare. Chordomas located in the jugular foramen are extremely rare, with a low incidence of 0.

Altered brain functional connectivity and correlation with psychological status in patients with unilateral pulsatile tinnitus.

The study investigated the alteration of brain functional connectivity (FC) patterns and analyzed the relationship between FC and psychological statue in pulsatile tinnitus (PT) patients by resting-state functional magnetic resonance imaging. The eligible PT patients (29) and healthy subjects (29) were enrolled. Brain activity, FC and clinical characteristics, including tinnitus handicap inventory, duration, sleep quality, anxiety, and depression were evaluated.

Characterization of B-BOX gene family and their expression profiles under hormonal, abiotic and metal stresses in Poaceae plants.

Background: B-box (BBX) proteins play important roles in plant growth regulation and development including photomorphogenesis, photoperiodic regulation of flowering, and responses to biotic and abiotic stresses.

Results: In the present study we retrieved total 131 BBX members from five Poaceae species including 36 from maize, 30 from rice, 24 from sorghum, 22 from stiff brome, and 19 from Millet. All the BBX genes were grouped into five subfamilies on the basis of their phylogenetic relationships and structural features.

Second branchial cleft anomalies in children: a literature review.

Branchial cleft anomalies are the second most common head and neck congenital lesions in children. It may sometimes be a part of branchio-oto-renal (BOR) syndrome, so in patients with branchial cleft anomalies associated with a complaint of auricular deformity or a similar history and findings in other family members, we should take an additional examination to find the possibility of BOR syndrome. Complete excision is essential for good prognosis.
