encoding a chromatin remodeling factor, is a killer causing hybrid sterility between rice species and .

The genetic mechanisms of reproductive isolation have been widely investigated within Asian cultivated rice (); however, relevant genes between diverged species have been in sighted rather less. Herein, a gene showing selfish behavior was discovered in hybrids between the distantly related rice species and . The selfish allele in the locus impaired male fertility, discriminately eliminating pollens containing the allele from in heterozygotes (/).

Different contributions of PROG1 and TAC1 to the angular kinematics of the main culm and tillers of wild rice (Oryza rufipogon).

PROG1 is necessary but insufficient for the main culm inclination while TAC1 partially takes part in it, and both genes promote tiller inclination in Asian wild rice. Asian wild rice (Oryza rufipogon), the ancestor of cultivated rice (O. sativa), has a prostrate architecture, with tillers branching from near the ground.

Treatment of Recurrent Intracranial Aneurysms After Neck Clipping: Novel Classification Scheme and Management Strategies.

Background: Recurrent aneurysms after initial clipping have been discussed as an important issue in the surgical management of aneurysm.

Objective: To report our experience with recurrent cerebral aneurysms after neck clipping and to discuss classification and recommended management.

Methods: Aneurysm treatments from a single institution over a 20-year period were retrospectively reviewed.

[Contribution of increasing age to carotid plaque morphology and symptoms].

Objective: Aging is considered to cause atherosclerotic changes in the carotid artery, but few studies have evaluated this relationship. In this study, we used carotid plaques removed from patients with carotid artery stenosis and investigated how aging contributes to carotid plaque morphology and symptoms.

Materials And Methods: A total of 60 patients(55 men, 5 women; mean age, 70.

[Ruptured aneurysm at the anomalous arterial wall of the distal anterior inferior cerebellar artery: a case report].

Distal anterior inferior cerebellar artery(AICA)aneurysms are rare, so its pathogenesis and treatment remain controversial. Here, we report the unique pathogenesis of a ruptured aneurysm in this area that was based on anomalous components as well as partial dissection of the arterial wall. A 61-year-old woman presented to our hospital with sudden headache and nausea.
