A new Bifidobacterium species is described based on the study of ten Gram-positive strains with fructose-6-phosphate phosphoketolase activity. They are part of a phenotypic group comprising 141 strains isolated from raw milk and raw milk cheeses in French raw milk cheese factories. This group was separated by a numerical analysis based on API 50CH, API 32A tests and growth at 46 degrees C. A strong similarity of 16S rRNA sequences (99.8%) was shown between strain FR62/b/3(T) and Bifidobacterium psychraerophilum LMG 21775(T). However, low DNA-DNA relatedness was observed between their DNAs (31%). The new isolates are able to grow at low temperatures (all ten strains up to 5 degrees C) and strain FR62/b/3(T) grows under aerobic conditions, as does B. psychraerophilum. However, contrary to B. psychraerophilum, they do not ferment L-arabinose, D-xylose, arbutin or melezitose, but they do acidify lactose. The DNA G+C content of FR62/b/3(T) is 56.4mol%. Therefore, the name Bifidobacterium crudilactis sp. nov. is proposed, with its type strain being FR62/b/3(T) (=LMG 23609(T)=CNCM I-3342(T)). [less ▲]

The term of dormancy is often used to describe the storability of potato tubers. A dormancy value or duration defines the period potato tubers can be stored before initiating sprouting. Characterization of dormancy value provides useful information to implement strategies for short or long-term storage of potato varieties and can be instrumental to schedule treatment of potato tubers with sprouting inhibitors. The dormancy values of the varieties are provided by breeders and research institutes. Those values can be retrieved from online databases. Comparison of the aforementioned online databases shows that the information is not available for all varieties and that this information can be variable and/or very different for some varieties. The variability can be explained by the heterogeneity of the methods used to determine the dormancy values (e.g. the use of different control varieties and the use of different dormancy scales). The aim of this study is to compare different statistical models based on linear regression analysis that could be used to calculate the dormancy value of a potato variety using field trials data and the corresponding post-harvest observations of tuber sprouting. To perform this comparison, we used dormancy value data collected for 210 potato varieties over 25 years in six locations in Switzerland (Swiss variety testing network datasets). This work provides a comparison of the performances of the different models that are tested and suggests novel methodologies to assess and calculate the dormancy values of the potato varieties.

Introduction: Different series emphasized the necessity of rehabilitation program after infiltration of platelet-rich plasma (PRP) in case of tendinopathy. However, most of them describe only briefly the reeducation protocol and these programs vary. Our aim was to extensively describe a specific standardized rehabilitation program. Methods: After a review of literature of post-PRP infiltration protocols, we had developed a standardized rehabilitation protocol. This protocol was evaluated by 30 subjects with chronic jumper’s knee who. A a standardised progressive sub-maximal eccentric program supervised by a physical therapist for 6 weeks was started 1 week post-infiltration. The patient benefited also from electromyostimulation, isometric strengthening and stretching of the quadriceps, cycloergometer and cryotherapy. After the supervised program, the patient had to make an auto-reeducation added to the reathletisation protocol for 6 more weeks which was followed by maintenance exercises up to 1 year. The assessments were made using a VAS, IKDC and VISA-P scores. Results: The VAS , IKDC and VISA-P scores decreased very significantly with time. The compliance to auto-reeducation was good. Conclusion: We proposed a simple and efficient protocol based on sub-maximal eccentric reeducation to add to PRP infiltrations in case of patellar tendinopathy. [less ▲]

Objectives: Repeted abutment connection and disconnections compromize the connective and epithelial sealing around implant components, leading to peri-implant bone remodeling (Abrahamsson, 1997). Placing the definitive abutment at the time of implant placement might be a treatment option to minimize this biological rupture. The aim of this study was to evaluate the effectiveness of pre-shaped zirconium abutments for immediate implant loading in the anterior maxilla. Materials and methods: A total of 13 patients needing the placement of one or several implant in the esthetic zone were treated with Regular Crossfit Bone Level (Straumann) implants. Implants were placed and immediately restored with a pre-shaped zirconium abutments and provisional resin crowns if the primary stability reached at least 20 N/cm2. Implant survival rate, biological and prosthodontic complications as well as peri-implant tissue status (papilla index) were recorded during a follow-up period of 1 year. Results: A total of 14 implants (8 incisors, 1 canines, 5 premolars) placed in 11 patients (4 men / 7 women) aged from 22 to 60 years old (48,5 +/- 11,5) could be assessed for the entire follow-up period. 2 patients dropped out. All implants reached an adequate primary stability (> 20N/cm2) to perform an immediate implant restoration. Straight pre-shaped Zirconium abutment was used in each case. Six implants were placed in socket preservation sites and five implants were placed simultaneously with a GBR. After a follow-up period of 1 year, all implants fulfilled survival criteria for dental implants with regard to osteointegration, including the absence of peri-implant radiolucency, implant mobility, suppuration, and pain. One abutment screw loosening was observed during the provisional period and no abutment fracture occurred. Definitive full ceramic-cemented restorations were successfully performed on each implant after a mean period of 6 months and no further complications occurred. In 11 out of 14 implants, an improvement of the papilla index was observed from baseline to 1 year follow-up whereas 3 implants showed a decrease of this index. Conclusion: The results from this prospective case series suggest that immediately restored implants using a final pre-shaped zirconium abutment in esthetic zone display favorable implant and prosthodontic outcomes and seems to allow an adequate papilla index improvement in most of the cases.

In (synthetic) holography and diffractive optics, the optical field is often decomposed in a set of spherical or plane waves. This gives sometimes some problems in calculating the Fourier transform. Because Gaussian beams are their own Fourier transform, it seems to be more natural to use Gaussian beams as basis functions. However, because Gaussian functions are no complete set of basis functions, it is necessary to extend the idea and to use rather Gaussian-Hermite wave functions as an orthonormal basis set. Those ideas can also be applied to general Self-Fourier Transform functions. [less ▲]

Understanding fine scale behavioral responses of fish to changes in abiotic characteristics of streams (in term of flow and water temperature) is an interesting innovative issue to improve river management of highly disturbed large rivers. Acoustic telemetry system have become an essential technology for such studies involving continuous (per second) and accurate tracking of fish movements. In the Rhône River (France), important hydrology and thermal contrasts are mainly explicated by the succession of dams and nuclear power plant from the Leman Lake (Switzerland). In this context, it is likely that fish are compelled to adapt their behaviour and their habitat selection in this changing environment. In order to test this hypothesis, a fixed acoustic telemetry survey was performed in the Rhône River during summer 2009 in front of the Bugey nuclear power plant which released warmed water within the river. A study site of 1.8 km long and 140 m wide was monitored using 32 hydrophones developed by HTI® (Hydroacoustic Technology Inc.). Sixty two fish mainly belonging to three species barbel (Barbus barbus), chub (Leuciscus cephalus) and wels catfish (Silurus glanis) were marked with acoustic tags (307 KHz; pulse rate ~ 3 sec.) and followed continuously during 89 days. Fish positions were coupled with a 2D hydraulic model to obtain main physical characteristics encountered by fish such as flow velocity, water depth, water temperature and substrate. The accuracy of the telemetry system was checked and a positional error less than 4 m was found in the channel (detection efficiency of 50 %) and less than 8 meters along the banks (detection efficiency of 20 %). Behavioral responses of fish were investigated through the individual mobility and activity during selected phases of flow (increase, decrease and stability) and water temperature changes (imposed by both warm water plumes and the rapid transition of deep cold waters from the Leman Lake discharged within the river). Mobility and activity of fish were particularly studied to determine the amount of movement associated with a change of abiotic conditions. The separate effects of each environmental factors on behavioral responses of fish were studied and interactions between factors were analyzed to highlight potential synergistic or antagonistic effects. Finally, movement rules (i.e. individual movement decisions in a particular surrounding environment) were analyzed to determine the role of perception of the environment by fish (i.e. how the fish feel the changes in physical habitat) in the use of space.

The clinical features of brachycephalic airway obstructive disease in 11 brachycephalic dogs are described in this study. The respiratory strategy was assessed before (n=11) and after (n=6) surgery using barometric whole-body plethysmography (BWBP), with the relationship between BWBP variables and the severity of the clinical signs assessed by the use of a respiratory score based on clinical, radiographic and endoscopic findings. Partial collapse of the left main bronchus was a common finding not previously described as part of the brachycephalic airway obstructive disease syndrome. Epiglottic cysts, laryngeal granulomas and nasopharyngeal turbinates in English Bulldogs were other previously unreported findings. No significant correlation between the respiratory score and any of the BWBP variables was detected. Compared to healthy dogs, brachycephalic dogs had a significantly lower Te/Ti ratio (expiratory time over inspiratory time), peak inspiratory flow (PIF) per kg bodyweight (BW), significantly higher peak expiratory flow (PEF) per kgBW, PEF/PIF, and enhanced pause. These variations are compatible with upper airway obstructions primarily in the extrathoracic airways. Following surgery, a significant decrease in PEF/PIF was detected. The study showed that BWBP could be used to characterise the respiratory strategy in brachycephalic dogs before and after surgery. [less ▲]

Purpose. To describe the gender, age, occupational status and diagnosis of dysphonic patients. Method. We retrospectively analyzed the medical records of 1079 patients examined at the Voice clinic of the University hospital of Liège in French-speaking Belgium. Results. Overall, seven out of 10 patients who attended the voice clinic for dysphonia were females. The patients’ ages ranged from 4 to 93 (mean=43.5). Females predominantly consulted at the age of 54 and males at the age of 9. Regarding the occupational status, workers represented more than half of our patients (53%), while 11.2% were unemployed, 15.4% were students, and 19.9% were retired. Regarding the diagnoses of the 1079 patients, nodules were the most common pathologies (n=182, 16.9% of the patients), prevailing in females (n=142, 18.8% of the females), encountered in 16.8% of the workers and 42.8% of the students consulting the voice clinic. Following nodules, laryngeal mobility disorders were diagnosed in 16.4% of the patients (n=177), mainly females (n=115), and was the most frequent diagnosis in retirees (n=75, 34.9%). Conclusions. The majority of the patients consulting the voice clinic for dysphonia were adult females, in their workforce, diagnosed with vocal nodules. The identification of the patients’ characteristics and diagnoses is important to develop treatments and prevention of dysphonia, estimate their costs, and allow comparisons across referral centers.

The aim of this study was to describe the embryos abortion process and the inheritance of the embryos abortion trait in Phaseolus vulgaris plants deficient in seed development. These plants were isolated within the second generation of an ethyl methanesulfonate (EMS) TILLING population of P. vulgaris cv. 'BAT93'. Mutant embryos show abnormalities mainly in suspensors, shoot apical meristem (SAM) and cotylédons from the globular to the cotyledon stages and abort before maturity compared to those observed in wild-types samples. Mutant embryos show also hyperhydricity and contain low amount of chlorophyll. Genetic analyses of F1, F2 and F3 populations from the crosses carried out between the mutagenized plants with aborting embryos and the wild-type plants indicated that the embryo abortion phenotype is maternally inherited and controlled by a single recessive gene. These Phaseolus mutant plants with aborting embryos constitute a valuable material for plant embryogenesis studies. [less ▲]
