Within the entire complex procedure required to measure dioxins and related compounds in biological matrices, the extraction step is often seen as a well controlled step. Although maybe true for many human and food-related matrices, the situation is very different for animal feed and feed ingredients. Specific European guidelines (e.g. Commission Directive 2006/13/EC, Commission Regulation (EC) No 152/2009) exist for animal feed but only list general requirements for the various stages of the procedure. The liberty is left to laboratories to select, for example, the tools used for the extraction steps. This has the advantage to allow ‘in-house’ methods to be used, as long as they satisfy with all the requirements of the EU Regulation. In that context, it is foreseen that the European Committee for Standardization (CEN) will soon propose a standard for the determination of PCDD/Fs and PCBs in animal feed that would be the reference method to be used to solve potential issues in case of dispute over results reported from different laboratories. A major point of concern is that it has been reported earlier1 that most commonly accepted extraction procedure can conduct to significantly different results for the extraction of dioxins and related compounds in feed and feed additives such as mineral clays and various oxides. Several non-instrumental and instrumental automated approaches are available for extraction. Soxhlet extractors have long been the most used tools for non-instrumental extraction of solids. They have proven to be very efficient but some limitations encouraged the development of other approaches based on instrumental techniques. For feed extraction, pressurized liquid extraction (PLE) (also branded as accelerated solvent extraction ASE®) is the technique of choice for high sample throughput. This study reports on the investigation of the use of various solvent mixtures, extraction temperatures, and instruments (parallel PLE, sequential ASE®) for the extraction of 17 PCDD/Fs and 12 dioxin-like PCBs in mineral clay, bovine feed, fish meal, and in-house quality control animal compound feed.

Onychomycosis represents a stubborn problem for the clinician facing up to the realities of antifungal treatments. There are obvious discrepancies between data given by in vitro antifungal testings, pharmacodynamics and pharmacokinetics, and those gathered from clinical experience. This critical review is an attempt at bridging the gap between in vitro and in vivo information about oral antifungals that aim to treat onychomycoses. Common sense shows that the in vitro concept of fungicidy cannot be simply extrapolated into clinical practice. Indeed, chlamidoconidia and arthroconidia present in vivo are much more resistant to antifungals than hyphae. Corneofungimetry may be a realistic bioassay in predicting antifungal activity in human infections. Boosting hyphae growth from conidia while taking antifungals is a new and appealing treatment modality that deserves controlled study. [less ▲]

A special cluster of filamentous, false-branched cyanobacteria, isolated from littoral mat samples in coastal lakes of the Larsemann Hills region (coll. by D. Hodgson) was studied by a polyphasic approach. This morphotype has several characters corresponding to the traditional genera Leptolyngbya (morphology of trichomes), Pseudophormidium (type of false branching) or Schizothrix (occasional multiple arrangement of trichomes in the sheaths). However, this cluster of strains is distinctly isolated according to its phylogenetic position (based on 16S rRNA gene sequences), and thus, a separate generic classification is justified. The cytomorphology of this generic entity is also characteristic. Therefore, a new genus (Plectolyngbya with the type species P. hodgsonii) was described. [less ▲]

Sensory irritation is directly bound to the concept of sensitive skin. A large proportion of the population, in particular young women, is affected. The reported symptoms are those of skin discomfort without any visible alteration of the skin. According to the subjects, the timing and the cutaneous sites, various perceptions occur, including pruritus, burning and stinging sensations. Sensory irritation is difficult to quantify because it remains subjective by essence. The condition is sometimes aggravated by some cosmetics, cleaning and cleansing products, wool contact and exposure to cold and dry climate. The responsible ingredients are often agents affecting functions of stratum corneum without being obvious chemical irritants. [less ▲]

Insertional mutagenesis was used in Chlamydomonas reinhardtii to isolate original mutants hypersensitive to multiple drugs and physical agents. Out of 5200 transformants analyzed, 13 mutants belonging to seven phenotypic classes were isolated. Five were exclusively sensitive to cadmium and represented two loci. The other mutants were pleiotropic and presented a cross sensitivity to several (2--6) of the following agents: cadmium, copper, lead, paraquat, hydrogen peroxide, UVC and light. In all mutants analyzed, the hypersensitive phenotype was most probably due to a single mutational event. The sensitivity of several pleiotropic mutants to a broad range of physical and chemical agents suggests that the disrupted genes are involved in multiple stress responses. [less ▲]

We report the discovery of an Antirrhinum MADS-box gene, FARINELLI (FAR), and the isolation of far mutants by a reverse genetic screen. Despite striking similarities between FAR and the class C MADS-box gene PLENA (PLE), the phenotypes of their respective mutants are dramatically different. Unlike ple mutants, which show homeotic conversion of reproductive organs to perianth organs and a loss of floral determinacy, far mutants have normal flowers which are partially male-sterile. Expression studies of PLE and FAR, in wild-type and mutant backgrounds, show complex interactions between the two genes. Double mutant analysis reveals an unexpected, redundant negative control over the B-function MADS-box genes. This feature of the two Antirrhinum C-function-like genes is markedly different from the control of the inner boundary of the B-function expression domain in Arabidopsis, and we propose and discuss a model to account for these differences. The difference in phenotypes of mutants in two highly related genes illustrates the importance of the position within the regulatory network in determining gene function. [less ▲]

Following three brief clinical reports, we review the literature concerning a rare cause of exudative pleural effusion: the presence of a foreign body in the pleural cavity. Frequently iatrogenical, this rare etiology of pleural effusion must be envisaged when this complication develops after any invasive peri-thoracic surgery and must be included in the differential diagnosis of recurrent pleural effusions. These effusions have a favorable prognosis after withdrawal of the foreign body. [less ▲]
