The clinical distribution of the Dupuytren's disease cords in the thumb and first web was examined in 100 consecutive patients with Dupuytren's disease. The precise anatomical relations of the cords were then studied in 25 patients undergoing Dupuytren's surgery for thumb and first web space disease. Thumb and first web space involvement was found in 28% of hands affected by Dupuytren's disease...

High Resolution Laryngeal Ultrasound for diagnosis of vocal cords lesions

Thyrotropin-releasing hormone (TRH) potentiated the monosynaptic reflex in isolated spinal cords obtained from 7- to 9-day-old rats. A concentration-dependent increase in the monosynaptic reflex was observed in spinal cords obtained from male but not from female or castrated male rats. In contrast, the magnitude of potentiation in cords from ovariectomized control female rats and in ovariectomi...

A 33-year-old phenotypic female presented with primary amenorrhea. The physical examination revealed no breast development, scanty axillary and pubic hair, normal female external genitalia, and a short blind vagina. The findings of magnetic resonance imaging, karyotyping, and hormonal examinations supported the diagnosis of XY partial gonadal dysgenesis. Laparoscopic surgery showed that spermat...

Optogenetic stimulation allows activation of cells with high spatial and temporal precision. Here we show direct optogenetic stimulation of skeletal muscle from transgenic mice expressing the light-sensitive channel Channelrhodopsin-2 (ChR2). Largest tetanic contractions are observed with 5-ms light pulses at 30 Hz, resulting in 84% of the maximal force induced by electrical stimulation. We dem...

The transcription factors SF-1 and WT1 play pivotal roles in mammalian gonadal development and sexual differentiation. In human embryos, both SF-1 and WT1 are expressed when the indifferent gonadal ridge first forms at 32 days post-ovulation. As the sex cords develop - providing morphological evidence of testis differentiation - SF-1 localises predominantly to developing Sertoli cells in the se...

BACKGROUND Managing "spaghetti syndrome," the tangle of therapeutic cables, tubes, and cords at patients' bedsides, can be challenging. OBJECTIVES To assess nurses' perceptions of the effectiveness of a novel banding device in management of spaghetti syndrome. METHODS A simple color-coded elastomeric banding strap with ribbed flaps was attached to bed rails of adult critical care patients t...

The aim of the current study was to investigate morphological and histological effects Bisphenol A on chicken Ross 308 during embryonic development total 150 eggs were randomly divided into five groups: negative control, positive control injected with con oil treatment groups administered different concentrations (0.005, 0.02 0.1 microliters/egg). second day incubation evaluation conducted days...
