Moth-eye nanostructures are a well-known example of biological antireflective surfaces formed by pseudoregular arrays of nipples and are often used as a template for biomimetic materials. Here, we provide morphological characterization of corneal nanostructures of moths from the Bombycidae family, including strains of domesticated Bombyx mori silk-moth, its wild ancestor Bombyx mandarina, and a...

Isolated bloody nipple discharge is rare in infancy and is usually idiopathic. Discharge commonly resolves spontaneously, and ultrasonography is a useful diagnostic technique to detect the cause of discharge. The authors report a 7-month-old boy who presented with unilateral spontaneous bloody nipple discharge for 1 month without signs of infection or mass.

Two trials, using a total of 3,200 male broilers, were conducted to compare the effects of a trough drinker versus three different heights on a nipple drinker system on body weight gain and feed:gain. The broilers were housed in temperature-controlled litter pens at 25 or 30 C. An 8-ft open trough was used. The nipple drinker heights were adjusted as 1) low (no neck stretch and drink from the s...

The milking unit can be detached at a milk flow rate of 400 g/min without having a negative effect on milk yield. Machine-on time is shortened and teat condition improved, and udder health does not seem to be affected. The threshold may be set even higher for cows milked more than twice daily. It is recommended that specific setting of switch points and delay times are evaluated for each farm. ...

OBJECTIVE To investigate factors associated with discontinuation of exclusive breastfeeding in the first month of lactation, in the city of Feira de Santana, Brazil. METHODS Cohort study with follow-up of 1,309 mother-child pairs selected from all maternities in the municipality. Data were collected in hospital and in home visits during the first month of life. Logistic regression analysis wa...

Despite the many empirical successes of QCD, there are a number of intriguing experimental anomalies that have been observed in heavy flavor hadroproduction, in measurements of azimuthal correlations in deep inelastic processes, and in measurements of spin correlations in hadronic reactions. Such phenomena point to color coherence and multiparton correlations in the hadron wavefunctions and phy...

BACKGROUND Many women experience breastfeeding difficulties. Sometimes these difficulties lead to breastfeeding cessation. Breastfeeding clinics provide support for women facing such problems. This study aims to describe the breastfeeding experience of women, particularly those who use the services of the breastfeeding clinic located in the Greater Quebec City area. METHODS This is a descript...

A 15-year-old male presented for evaluation of a volar forearm mass that he noticed four years before. The mass was not painful and his main concern was cosmesis. The mass was two centimeters in diameter with a pinpoint central sinus and scant drainage. After excision, the pathology report noted pilosebaceous units and smooth muscle bundles, consistent with an accessory nipple. In addition, the...

The existence of piercings dates through history, with reports of Roman centurions wearing nipple rings in their breast plates as a sign of loyalty to their Emperor. In addition the Mayans pierced their tongues as part of spiritual rituals, while Queen Victoria’s husband, Prince Albert of Saxe-Coburg and Gotha, is rumoured to have had his penis pierced. In recent times the prevalence of piercin...
