Many studies have focused on the significant role of biofilm formation by Bacillus in the biocontrol process. Bacillus pumilus HR10 is a plant growth-promoting rhizobacterium with multiple biocontrol functions, including promoting growth, controlling pathogens, and assisting in the formation of mycorrhizae. Currently, there is no relevant report on the biofilm formation of B. pumilus HR10 and its influencing factors. B. pumilus HR10 was found to easily form a stable biofilm structure on the surface of media, with awesome swarming ability. The optimum temperature for biofilm formation was 37 °C. B. pumilus HR10 formed most obviously at pH 7.0 and was not extremely sensitive to acidic or alkaline conditions. Most of the polysaccharide components of plant root exudates promoted the biofilm formation by B. pumilus HR10, with glucose having the greatest promoting effect. Low concentrations of Fe2+, Mg2+, Ca2+, K+, and Na+ enhanced biofilm formation. In summary, biofilm formation can improve the tolerance of B. pumilus HR10 to salt and certain heavy metal ion stresses and contribute to its application in different plants and soils with high salinity or heavy metals in the field.The present work investigated the effect of camel's fetal fluids on a variety of bacterial and fungal pathogens. Ten samples of camel's amniotic and allantoic fluids were collected aseptically during parturition and their antimicrobial activities were evaluated by disc diffusion method and minimum inhibitory concentration (MIC) assay. The majority of tested pathogens were inhibited by both fluids up to 25% concentration. The fluids showed zones of inhibition ranging from 8 to 30 mm. The most pronounced inhibition was detected for Staphylococcus aureus, Listeria monocytogenes, Klebsiella pneumonia, and Aspergillus niger but the weak inhibition was obtained for Enterococcus faecalis, Bacillus subtilis, and Candida albicans. check details Also, the MIC values of amniotic fluids (0.25-2 μg/ml) against Gram-positive bacteria and yeast were lower than the values of allantoic fluids (2-8 μg/ml). But in Gram-negative bacteria and molds, the MIC values of allantoic fluids (0.5-2 μg/ml) were the lowermost. Mucor circinelloides was the only pathogen that resisted both fluids. Analysis of fluid samples revealed the presence of several factors that are known to act as antimicrobial. All tested camel's fetal fluids harbored immunoglobulins, complements, and transferrin. Lysozyme was present in only one of 10 examined samples. We firstly report the prevalence of a profound in-vitro antimicrobial activity of camel's fetal fluids. This activity encourages their use as therapeutic alternative agents to overcome multidrug resistance problems.BACKGROUND Compared to the international literature a higher proportion of German nursing home residents (NHR) die in hospital. Data on longer periods before death and on regional differences are not available. OBJECTIVE The frequency of hospitalizations of NHR in different periods during their last year of life were investigated. Differences between age, sex, level of nursing care, dementia and federal states were also assessed. MATERIAL AND METHODS This study used data of a large German health insurance fund and included NHR aged 65+ years who died between 1 January 2010 and 31 December 2014. We assessed the proportion of NHR with at least one hospitalization during different periods before death. In-depth analyses were conducted for 0 (which corresponds to in-hospital death), 28 and 365 days before death. RESULTS Of the 67,328 deceased residents (mean age 85.3 years, 69.8% female), 29.5% died in hospital. A total of 51.5% and 74.3% were hospitalized during the last 28 and 365 days of life, respectively. These values were higher in the eastern parts of Germany. Males were hospitalized more often than women in all time periods. A higher care dependency was associated with fewer hospitalizations, especially shortly before death. There was no noticeable difference in the frequency of hospitalization between NHR with and without dementia. CONCLUSION Approximately half of all NHR in Germany are hospitalized during the last month of life and one third die in hospital, which is relatively high compared to the international literature. No major differences were found between NHR with and without dementia, which is also contradictory to international studies. Overall, there is a need to optimize palliative care for NHR in Germany.Antiphospholipid syndrome (APS) was first identified in patients with systemic lupus erythematosus (SLE) and frequent occurrence of thromboembolic complications and miscarriages accompanied by detection of anticardiolipin antibodies (aCL). When APS was also later found without an underlying SLE, the so-called primary APS was distinguished from its secondary form with SLE. Even more specific than aCL are the lupus anticoagulant (LA) and antibodies against beta‑2 glycoprotein I (aB2GP I). In recent years, it has become evident that the risk of (further) thromboembolic and obstetric complications is markedly increased if all three serological criteria of APS (aCL, aB2GP I and LA), the so-called triple positivity, are present (high-risk profile). Immunosuppression is not effective in preventing further thromboembolic complications of APS. Low-dose aspirin (LDA), heparin and vitamin K antagonists are used in primary and secondary prophylaxis. The direct oral anticoagulants have an increased risk of complications compared to these treatments and should not be used in cases of high-risk APS.AIMS/HYPOTHESIS Physical inactivity, low mitochondrial function, increased intramyocellular lipid (IMCL) deposition and reduced insulin sensitivity are common denominators of chronic metabolic disorders, like obesity and type 2 diabetes. Yet, whether low mitochondrial function predisposes to insulin resistance in humans is still unknown. METHODS Here we investigated, in an intervention study, whether muscle with low mitochondrial oxidative capacity, induced by one-legged physical inactivity, would feature stronger signs of lipid-induced insulin resistance. To this end, ten male participants (age 22.4 ± 4.2 years, BMI 21.3 ± 2.0 kg/m2) underwent a 12 day unilateral lower-limb suspension with the contralateral leg serving as an active internal control. RESULTS In vivo, mitochondrial oxidative capacity, assessed by phosphocreatine (PCr)-recovery half-time, was lower in the inactive vs active leg. Ex vivo, palmitate oxidation to 14CO2 was lower in the suspended leg vs the active leg; however, this did not result in significantly higher [14C]palmitate incorporation into triacylglycerol.
