The hormone auxin is actively transported throughout plants via protein machineries including the dedicated transporter known as PIN. The associated transport is ordered with nearby cells driving auxin flux in similar directions. Here, we provide a model of both the auxin transport and of the dynamics of cellular polarization based on flux sensing. Our main findings are: (i) spontaneous intrace...

A new design consideration is explored for a hair-pin resonator. A grounding via at the mid-point of the resonator acts as a perturbation to split the resonant frequencies. The via also suppresses even harmonics of the fundamental. The principle operation of the hair-pin resonator with a via is analyzed and verified by measurement. It is shown that such a hair-pin resonator can be made more com...

PIN diodes are fundamentally similar to standard diodes, but have an RF impedance that is determined by an externally supplied bias current. Their versatility makes them excellent building blocks in a wide variety of configurations within each product category, which allows diverse system requirements to be served. In short, the PIN diode enables all systems – from the least complex to the most...

OBJECTIVE In our clinical practice, we have noted a caliber change of the posterior interosseous nerve (PIN) at the elbow as seen in the long axis on sonography simulating nerve entrapment. The objective of this study was to characterize the PIN using sonography in asymptomatic individuals. METHODS Our study retrospectively characterized the PIN in 50 elbows of 47 asymptomatic patients with s...

Cross-pin fixation of hamstring grafts for anterior cruciate ligament reconstruction was developed with hopes of improving on potential problems associated with interference screw and button fixation methods. However, cross-pins are a relatively new method of graft fixation and there are limited data on this technique. We report 2 cases in which reoperation was necessary after complications ass...

Auxin participates in a multitude of developmental processes, as well as responses to environmental cues. Compared with other plant hormones, auxin exhibits a unique property, as it undergoes directional, cell-to-cell transport facilitated by plasma membrane-localized transport proteins. Among them, a prominent role has been ascribed to the PIN family of auxin efflux facilitators. PIN proteins ...

BACKGROUND Alopecia Areata (AA) is a disease characterized by hair loss that is widely believed to be autoimmune in origin. Thus treatment is generally aimed in this direction using immune inhibitors such as steroids and PUVA. OBJECTIVE To describe a variant of AA, Pseudo Alopecia Areata, caused by a particular cupola pin holder (tic-tac) and to offer a non-pharmacological treatment option (N...

BACKGROUND Pin tract infection is a common complication of external fixation. It usually heals after treatment with debridement, antibiotics, and/or pin removal, only rarely developing into delayed osteomyelitis. We treated two patients with delayed methicillin-resistant Staphylococcus aureus-induced osteomyelitis of the tibia following pin tract infection. CASE PRESENTATION One patient, a di...

Article history: Received 2.10.2012 Received in revised form 30.1.2013 Accepted 1.3.2013 Heat production of friction stir welding (FSW) is a fundamental phenomenon that affects the welding quality. Early studies have been focused on investigating and understanding the heat production and temperature distribution of the welding plate. However, very few studies have been done to analyze the stres...
