Implementation of complex computer circuits assembled from the bottom up and integrated on the nanometer scale has long been a goal of electronics research. It requires a design and fabrication strategy that can address individual nanometer-scale electronic devices, while enabling large-scale assembly of those devices into highly organized, integrated computational circuits. We describe how such a strategy has led to the design, construction, and demonstration of a nanoelectronic finite-state machine. The system was fabricated using a design-oriented approach enabled by a deterministic, bottom-up assembly process that does not require individual nanowire registration...

Archimedean tilings are periodic polygonal tessellations that are created by placing regular polygons edge-to-edge around a vertex to fill the plane. Here we show that three- and four-arm DNA junction tiles with specifically designed arm lengths and intertile sticky-end interactions can be used to form sophisticated two-dimensional (2D) and three-dimensional (3D) tessellation patterns. We demonstrate two different complex Archimedean patterns, (3(3).4(2)) and (3(2).4.3.4), and the formation of 2D lattices, 3D tubes, and sealed polygon-shaped pockets from the tessellations...

DNA-based self-assembly is a unique method for achieving higher-order molecular architectures made possible by the fact that DNA is a programmable information-coding polymer. In the past decade, two main types of DNA nanostructures have been developed: branch-shaped DNA tiles with small dimensions (commonly up to ∼20 nm) and DNA origami tiles with larger dimensions (up to ∼100 nm). Here we aimed to determine the important factors involved in the assembly of DNA origami superstructures. We constructed a new series of rectangular-shaped DNA origami tiles in which parallel DNA helices are arranged in a zigzag pattern when viewed along the DNA helical axis, a design conceived in order to relax an intrinsic global twist found in the original planar, rectangular origami tiles...

A total of 16 women with endometriosis 25 to 36 years old were examined. Of these, 6 presented with primary infertility, 10--with secondary intertility, 7 female patients had endometriosis concurrent with other localizations. The treatment was with duphaston (dydrogesteron), 10 mg (5 mg twice a day) beginning from day 5 till 25 of the menstrual cycle for 6 months. The control echography and hysteroscopy permitted ascertaining regression of endometrioid foci in 13 female patients. According to the histological findings in 15 women the endometrium corresponded to the proliferative phase of the menstrual cycle, with its focal hyperplasia having been noted in 1 woman...

OBJECTIVE: A dietary survey of obese and control men was conducted through 24-hour dietary recalls administered by telephone at 12 times selected randomly over a period of 3 months. Energy and macronutrient intake and distribution were studied for all days of the week. SUBJECTS: Eighty-six obese men, 20 to 60 years old, body mass index (BMI) = 37.7 +/- 4.4 (mean +/- standard deviation) from the waiting list of the outpatient clinic and 6I normal-weight (BMI = 23...

The occurrence of sperm antibody in serum and cervical mucus of women from intertile couples in the serum of their male partners, as well as cellular immunity to sperm, has been studied by agglutination and immobilization techniques. For a total of about 260 couples, the tests on serum showed that 18% of the women and 8% of the men were positive by the Kibrick technique and that 15% of the women and 4% of the men were positive by the F-D technique. The women who were positive in their cervical mucus were 8% of the group by the K-agg (Kibrick agglutination) technique, 2% by the MIS-agg...
