Spider silk possesses a unique combination of high tensile strength and elasticity resulting in extraordinarily tough fibers, compared with the best synthetic materials. However, the potential application of spider silk and biomimetic fibers depends upon retention of their high performance under a variety of conditions. Here, we report on changes in the mechanical properties of dragline and cap...

This study investigates the writing style change of two Turkish authors, Çetin Altan and Yaşar Kemal, in their old and new works using respectively their newspaper columns and novels. The style markers are the frequencies of word lengths in both text and vocabulary, and the rate of usage of most frequent words. For both authors, t-tests and logistic regressions show that the length of the words...

To explore in detail the relationships between basal lamina (BL) and regenerating cells, we have studied the reconstruction of skeletal muscle fibers and their associated capillaries in portions of rat and rabbit skeletal muscles after injury with either freezing, ischemia, or in situ autografting . Each type of injury produces complete necrosis of cells . The BL, however, remains intact in the...

2 SUMMARY We analyzed fiber type composition of the soleus and extensor digitorum longus (EDL) muscles of 3-to 19-month-old male and female inbred Lewis strain rats determined by histochemical demonstration of mATPase activity. The rats were divided into four groups of the mean age of 3, 6, 9 and 14 months. We found that the soleus muscle of 3-month-old rats contained significantly more of fast...

We investigated the effects of aging on Drosophila melanogaster indirect flight muscle from the whole organism to the actomyosin cross-bridge. Median-aged (49-day-old) flies were flight impaired, had normal myofilament number and packing, barely longer sarcomeres, and slight mitochondrial deterioration compared with young (3-day-old) flies. Old (56-day-old) flies were unable to beat their wings...

The mechanisms underlying the development of painful and nonpainful neuropathy associated with diabetes mellitus are unclear. We have obtained microneurographic recordings from unmyelinated fibers in eight patients with diabetes mellitus, five with painful neuropathy, and three with neuropathy without pain. All eight patients had large-fiber neuropathy, and seven patients had pathological therm...

Effects of gravitational loading or unloading on the gain of the characteristics in soleus muscle fibers were studied in rats. The tail suspension was performed in newborn rats from postnatal day 4 to month 3, and the reloading was allowed for 3 mo in some rats. Single expression of type I myosin heavy chain (MHC) was observed in approximately 82% of fibers in 3-mo-old controls, but the fibers ...

Papular elastorrhexis is a rare cutaneous disorder that occurs predominantly during adolescence. The disorder is characterized by asymptomatic indurated white or flesh papules showing decreased and fragmented elastic fibers in the dermis. We herein report on a 12-year-old girl with multiple asymptomatic white, nonfollicular, firm papules scattered on the extremities and trunk. Histological exam...
