CONTEXT Many styles of foot pads are commonly applied to reduce immediate pain and pressure under the foot. OBJECTIVE To examine the effect of 3 different foot pads on peak plantar pressure (PPP) and mean plantar pressure (MPP) under the first metatarsophalangeal joint (MTPJ) during slow running. DESIGN A 4 (pad) x 4 (mask) repeated-measures design. SETTING University athletic training cl...

DiAgnosis: Digital mucous cyst. Digital mucous cysts are usually found on the dorsum of the fingers, most commonly on the distal phalanx. Rarely, lesions can present on the toes. The cysts appear bluish and when punctured drain a clear gelatinous material. Two different entities have been described. One involves the base of the nail. These lesions can be increasingly destructive due to pressure...

The tail of bacteriophage T4 consists of a contractile sheath surrounding a rigid tube and terminating in a multiprotein baseplate, to which the long and short tail fibers of the phage are attached. Upon binding of the fibers to their cell receptors, the baseplate undergoes a large conformational switch, which initiates sheath contraction and culminates in transfer of the phage DNA from the cap...

[1] We investigate the hypothesis that the 10 km diameter dome-shaped features seen on Europa’s surface are caused by strongly temperature-dependent convection, in which upwellings form isolated diapirs or thermals. We use the observed lower limit on dome diameter of 4 km to deduce that the conductive (stagnant) lid thickness must be 5 km. Such a lid thickness implies a minimum surface heat flu...

In this report, we present a new method for generating a high-density (2D) droplet array using double-layered polydimethylsiloxane (PDMS) templates containing honeycomb microwells. Without external flow control, a dropleton-template (DOT) was created by utilizing capillary forces associated with the interfacial tension between the aqueous and oil phases. The DOT process involved three simple st...

Ocular surface or epibulbar dermoid lesions may present as limbal dermoids at the corneal limbus or dermolipomas in the conjunctival fornix. The purpose of this study is to review clinical features of ocular surface dermoids (grade I), with the visual axis unaffected, in pediatric patients, in order to find key features for making clinical decision, either resection or observation. The study in...
