A retrospective study of 260 industrial amputees was undertaken to determine the long-term functional results of partial foot amputations following trauma. Follow-up ranged from 1 to 68 years with a mean of 16 years. Of 113 partial foot amputees (118 amputations) who had retained their original amputation, the functional end-results were 43% good, 38% fair and 19% poor. Lisfranc and Chopart amp...

The circular dichroism data on 17 adenine nucleosides show that the 260- and 207-mmu absorption systems of the adenine chromophore each contain at least two electronic transitions. The CD maxima are commonly found at around 260, 220, and 200 mmu, and occasionally at 240 mmu. Solvent studies suggest that these CD bands arise from pi-pi(*) transitions. A weak absorption band that obeys the McConn...

We report pulsed emission from an optically pumped lead-salt vertical-cavity surface-emitting laser with a PbSe/PbSrSe quantum-well active region. The lasing wavelength of l54.44 mm is nearly constant over the temperature range 200–280 K, and the threshold is only 10.5 kW/cm at 260 K, where the gain peak and cavity mode are in resonance. Over 330 mW of peak power is emitted at 260 K, into a cir...

Typically, the first thing one wants to know about a DNA preparation is its concentration and purity. Both can be determined by measuring the absorption of ultraviolet light. DNA absorbs UV more or less strongly depending upon the wavelength. We will be using a NanoDrop spectrophotometer, which takes measurements at wavelengths of 260 and 280 nm, and in addition determines an absorption spectru...

Camellia oleifera is a woody oil tree with overlapping flower bud differentiation and fruit maturation. Therefore, mechanical harvesting of fruits leads to abscission. The present study investigated the effects number per on growth, yield, nutrient accumulation, fatty acid composition in C. oleifera. Here, we set different numbers by thinning flowers. Heavy (T2 T3) significantly reduced yield p...

Introduction: Chronic ethanol consumption leads to significant functional and structural changes in the mitochondria of heart brain, increasing generation reactive oxygen species. Therefore, search for substances, which improve state and, meantime, reduce oxidative stress, is relevant.
 Materials methods: 10-months-old Wistar female rats were used experiments. alcohol intoxication (CAI) wa...

Latar belakang: Parameter nilai kemurnian yang dianalisis dari panjang gelombang dengan rasio 260/230 merupakan parameter validasi sekunder digunakan untuk melakukan analisis mutu DNA hasil isolasi pada produk nugget ayam. Tujuan: Tujuan dilakukannya penelitian ini adalah memberi informasi tentang dibaca 260/230. Dengan diperolehnya diharapkan dapat manfaat terhadap sejenis relevan. Metode: Met...

Large White females were fed on a plane of nutrition close to ad libitum during the entire experimental period (CTRL group, n = 48) or restricted during a limited period of their growth (RP1 group: 28-62 kg, RP2 group: 64-96 kg, RP3 group: 97-131 kg, n = 48/group). Blood samples were taken before 200 and 230 days of age in order to detect cyclic gilts by assaying their progesterone levels. Anim...

Biochemical experimentation generally requires accurate knowledge, at an early stage, of the nucleic acid, protein, and other biomolecular components in potentially heterogeneous specimens. Nucleic acids can be detected via several established approaches, including analytical methods that are spectrophotometric (e.g., A(260)), fluorometric (e.g., binding of fluorescent dyes), or colorimetric (n...
