Purpose To investigate the feasibility of pediatric cataract monitoring and morphologic classification using slit lamp-adapted anterior segmental photography in a large cohort that included uncooperative children. Methods Patients registered in the Childhood Cataract Program of the Chinese Ministry of Health were prospectively selected. Eligible patients underwent slit-lamp adapted anterior s...

Porous hydroxyapatite was prepared in order to be used as a drug carrier and promote bone ingrowth. For this purpose, the microstructure should have interconnective pores and micro as well as macro porosity, for bone cell adhesion and bone ingrowth. The porous hydroxyapatite prepared by the burn-out method exhibits all these features. For measuring porosity, SEM analysis, mercury intrusion poro...

Learning and understanding natural languages are usually considered as independent tasks in natural language processing. These two tasks, however, are strongly interrelated and are presumably unsolvable as separate problems. In this paper, we present an algorithm called Frequent Rule Graph Miner (FRGM) that tackles these problems by alternately improving on the language model and the example in...

A bovine rotavirus was adapted to serial propagation in Madin Darby bovine kidney (MDBK) cells. Virus of cell culture origin when examined by electron microscopy exhibited characteristic rotavirus morphology and had a typical RNA electropherotype on polyacrylamide gel electrophoresis. Mean IgG concentration in the first colostral whey was 62.80 +/- 6.56 mg/ml in cows and 104.40 +/- 31.12 mg/ml ...

Bees are predominantly diurnal; only a few groups fly at night. An evolutionary limitation that bees must overcome to inhabit dim environments is their eye type: bees possess apposition compound eyes, which are poorly suited to vision in dim light. Here, we theoretically examine how nocturnal bees Megalopta genalis fly at light levels usually reserved for insects bearing more sensitive superpos...

Pseudomonas aeruginosa is well adapted to grow in anaerobic environments in the presence of nitrogen oxides by generating energy through denitrification. Environmental cues, such as oxygen and nitrogen oxide concentrations, are important in regulating the gene expression involved in this process. Recent data indicate that P. aeruginosa also employs cell-to-cell communication signals to control ...

Late Cambrian to early Ordovician trilobites, the family Olenidae, were tolerant of oxygen-poor, sulfur-rich sea floor conditions, and a case is made that they were chemoautotrophic symbionts. Olenids were uniquely adapted to this habitat in the Lower Paleozoic, which was widespread in the Late Cambrian over Scandinavia. This life habit explains distinctive aspects of olenid morphology: wide th...

In orthopedic treatment an attempt is being made to influence the morphology of the craniofacial skeleton. According to Wolff’s law, “the structure and shape of a bone becomes progressively adapted to all the changing mechanical forces exerted on the bone; as a whole bone represents function and responds to stress placed on it”. The sutures in the craniofacial skeleton are remodeled as secondar...

For the first time, hen egg white coagulum was utilized as a surface modification agent for biomimetic multilevel structured nanomaterials (BMSN). By using a straightforward thermal control process, hen egg white can be coagulated in a precisely tailored manner, which is specifically adapted to the morphology of BMSN. Consequently, the structural stability, hydrophobicity and biocompatibility o...
