The present study analyzes the kinetics of the in vivo degradation of hydrophilic Mitrathane in the peritoneal cavity of mice over a period ranging from 1 to 180 days. The mechanical milling of the polyurethane films produced regularly flattened fragments that in vivo spontaneously oriented into piles. The morphological observations and analysis with the aid of an image analysis system demonstrated that after seven days of swelling the polymer fragments undergo a continuous degradation that leads to an irregular thinning and phagocytosis of the smaller fragments by macrophages with very little chronic inflammation response from surrounding tissues.

Wood-inhabiting fungi play a key role in forest ecosystems and constitute an essential part of forest biodiversity. We therefore examined the composition and abundance of wood-inhabiting fungi by three methods: sporocarp counts, mycelial culturing and direct amplification of internal transcribed spacer terminal restriction fragment length polymorphism from wood combined with sequencing of reference rDNA. Seven-year-old slash piles left after a thinning were analyzed in a 50-year-old Norway spruce plantation. Fifty-eight fungal species were detected from the piled branches and treetops. More species were revealed by sporocarp counts and cultured mycelia than by direct amplification from wood. In principle, sporocarp monitoring may reveal all fruiting taxa, but it poorly reflects their relative abundance in the wood. In contrast, terminal restriction fragment length polymorphism will record the most frequent fungal taxa in the wood, but it may overlook uncommon taxa. Culturing mycelia from wood gives a bias towards species favoured by the cultural medium. The results demonstrate the advantage and the limitations of these methods to be considered in analyses of fungal communities in wood.

The investigation objective was to estimate the role of nontraumatic anal sphincter (AS) stretching, as a leading factor of success in minimally invasive and/or plastic proctological interventions. One-centre randomized investigation was performed in 83 patients: In 22 of them the AS fissura was revealed (in 16), suprasphincteric fistula (in 3) and coexistent rectocele 2-3 Ap (according to POP-Q classification) with thinning of the AS anterior segment, the degree III hemorrhoids and anterior AS fissure presence. Ninety units of botulotoxin preparation (Disport) were injected between internal and external AS portions 5-15 days preoperatively. The treatment results without botulotoxin injection were compared retrospectively. After botulotoxin injection performance the AS spasm elimination was noted, leading to the pain subsiding promotion before and postoperatively in all the patients observed. The spasm elimination have permitted to escape the anal high fistula recurrence as a result of the mucosal flap shift after intraluminal closure of the fistula or because of the fistula intermuscular electrowelding "suture" rupture, also have guaranteed the plastic sutures on AS, even while the stage II-III rectocele presence, not depending of performance of its simultant surgica correction.

Forest restoration often includes thinning to reduce tree density and improve ecosystem processes and function while also reducing the risk of wildfire or insect and disease outbreaks. However, one drawback of these restoration treatments is that slash is often burned in piles that may damage the soil and require further restoration activities. Pile burning is currently used on many forest sites as the preferred method for residue disposal because piles can be burned at various times of the year and are usually more controlled than broadcast burns. In many cases, fire can be beneficial to site conditions and soil properties, but slash piles, with a large concentration of wood, needles, forest floor, and sometimes mineral soil, can cause long-term damage. We describe several alternative methods for reducing nonmerchantable forest residues that will help remove excess woody biomass, minimize detrimental soil impacts, and create charcoal for improving soil organic matter and carbon sequestration.
