Over 90% of Siberian hamsters (Phodopus sungorus) fail to reentrain to a 5-h phase delay of a 16:8-h photocycle. Because constant darkness (DD) restores rhythms disrupted by constant light, we tested whether DD could also restore entrainment. DD began 0, 5, or 14 days after a 5-h phase delay, and the light-dark cycle was reinstated 14 days later. All hamsters exposed to DD on day 0 reentrained,...

There are numerous dermatoses which may cause cicatricial alopecia when localized on the scalp, such as chronic discoid lupus erythematosus (DLE), lichen planus, graft-versus-host disease, dermatomyositis, scleroderma, cicatricial pemphigoid, porphyria cutanea tarda, follicular mucinosis, perifolliculitis capitis abscedens, lichen sclerosus et atrophicus, necrobiosis lipoidica, sarcoidosis, etc...

The phenology of Lacanobia subjuncta (Grote & Robinson) (Lepidoptera: Noctuidae) was investigated in 30 apple orchards in central Washington state and northeastern Oregon from 1998 to 2001 (57 total orchard-yr). Adult captures in pheromone-baited traps were fit to a Weibull distribution to model emergence of the first and second generations. Initial capture of first generation adults was observ...

62 Indian Dermatology Online Journal | Volume 9 | Issue 1 | January‐February 2018 Sir, Darier disease [DD; Darier‐White disease or (dys) keratosis follicularis], is an autosomal dominant disorder of keratinization with characteristic dermatologic findings such as keratotic papules on the seborrheic regions, brittle nails and longitudinal erythronychia, and palmoplantar pitting. Hypopigmented ma...

Introduction.?This is a comparatively rare condition and we have been able to find only one case which has been reported as occurring in an Indian patient. Raj an and Rangiah (1941) described a case with the typical triad of urethritis, polyarthritis and skin lesions. Sutton and Sutton in their classical book on skin diseases have excellent illustrations of the skin condition and quote Roth (19...

Keratosis lichenoides chronica (KLC) is a rare chronic hyperkeratotic disorder that typically affects patients aged 20 to 50 years. Its distinct clinical presentation in the pediatric population has raised speculation that the adult and pediatric variants of this disorder may be entirely separate disease entities. We present a case of adult-type KLC manifesting during childhood in a 14-year-old...

Duncan and Humphreys (1989) identified two key factors that affected performance in a visual search task for a target among distractors. The first was the similarity of the target to distractors (TD), and the second was the similarity of distractors to each other (DD). Here we investigate if it is the perceived similarity in foveal or peripheral vision that determines performance. We studied se...

Erythromelanosis follicularis faciei is a rare sporadic condition of unknown etiology characterized by reddish-brownish patches and follicular papules that appear commonly on the face and rarely on the neck. Herein, we report a 16-year-old male who had asymptomatic facial skin lesions since early childhood. His family history revealed a similar case in his younger brother. His parents are not c...

A modified 2D-SUPER technique is demonstrated to allow independent measurement of the principal values of the chemical-shift tensors of overlapping protonated and unprotonated carbons. The insertion of a dipolar-dephasing period into the sequence causes loss of signal from protonated carbons. The spectrum obtained with this modification allows one to determine the principal values of the unprot...
