A 11-year-old boy with genetically confirmed MELAS (mitochondrial encephalopathy, lactic acidosis, and stroke-like episodes syndrome with mutation at mt.3243A>G) presented with extreme fatigue. Upon presentation, he had elevated lactic acid of 5.2 mmol/L. His magnetic resonance imaging scan of the

Degeneration of the optic pathway has been reported in various animal species including cattle. We experienced a case of bilateral optic tract degeneration characterized by severe gliosis in a Japanese black cattle without any obvious visual defects. To evaluate the significance, pathological nature

Supersymmetric black holes are characterized by a large number of degenerate ground states. We argue that these black holes, like other quantum mechanical systems with such a degeneracy, are subject to a phenomenon which is called the geometric or Berry's phase: under adiabatic variations of the

Ten cases of myxomatous degeneration of the heart valves in Black subjects are described. The striking features, compared with other series, were the comparative youth of the patients and the predominance of aortic valve involvement. There was also a significant percentage of control subjects with

OBJECTIVE To characterize choroidal neovascularization (CNV) in black patients examined at a retinal disease referral center. METHODS Retrospective review of the medical records of all patients diagnosed as having CNV to identify black patients with CNV. METHODS Single tertiary retinal referral

Various types of hereditary retinal degeneration have associated posterior subcapsular cataract (PSC). It has been claimed that in the Royal College of Surgeons (RCS) rat model of hereditary retinal dystrophy, the cataract is manifested unpredictably and does not display Mendelian inheritance. It ws

During the past 8 years, extended temporal and broadband spectroscopic studies carried out by x-ray astronomical satellites have led to the identification of specific compact x-ray sources as accreting neutron stars, black holes, and degenerate dwarf stars in close binary systems. Such sources

Autosomal dominant motor system degeneration has been described primarily in Portuguese families from the Azorean Islands. The symptoms include various combinations of ataxia, pyramidal and extrapyramidal signs, appendicular dystonias, tics, ophthalmoplegias, and peripheral neuropathies with

During an 18-year period, 4.1% (34/831) of male deer (Odocoileus hemionus columbianus) killed on a field station during the autumn hunting season had velvet-covered, often misshapen antlers, and at least two deer had testicular atrophy (gonads from most deer were not available for examination).

I present a microscopic description of Hawking radiation in sonic black holes. A one-dimensional Fermi-degenerate liquid squeezed by a smooth barrier forms a transonic flow, a sonic analog of a black hole. The quantum treatment of the noninteracting case establishes a close relationship between

Two Japanese Black bull calves from a dam showed muscular weakness and became recumbent after birth. At necropsy, skeletal muscles, including face, neck, body and proximal and distal forelimb and hindlimb were extremely pale in color and edematous. Histopathological examination of skeletal muscles

Two-dimensional (2D) black phosphorus (BP) has attracted broad interests but remains to be synthesized. One of the issues lies in its large number of 2D allotropes with highly degenerate energies, especially 2D blue phosphorus. Here, we show that both nitrogen and hole-carrier doping can lift the

Men from a working population of black gold-miners were studied prospectively during an 8-month period to determine the incidence and aetiology of seizures in this population. Computed tomography (CT) of the brain was the primary investigation. From the total population of 97,000, 175 men with

BACKGROUND Menopause can be a distressing and disruptive time for many women, with many experiencing hot flushes, night sweats, vaginal atrophy and dryness. Postmenopausal women are also at increased risk of osteoporosis. Interventions that decrease the severity and frequency of these menopausal

A captive black rhinoceros (Diceros bicornis) with a hoof abscess was treated with long-term antibiotic therapy. After 9 months of treatment, there was rapid deterioration, marked weight loss and reluctance to stand. Profuse, bilateral epistaxis developed accompanied by collapse and the animal was
