Authors: Wilemska-Kucharzewska K. , Kózka M. , Spałkowska M. , Kucharzewski M. 
Published: December 2013

SummaryAim: To assess the efficiency of application of new membranous dressing with silver ions in patients with chronic venous ulceration.Methods: 58 patients were divided randomly into two groups. In group A (n=30) mean ulcer surface area was 8.52 cm2, in group B (n=28) mean wound surface area was 8.29 cm2. In group A membranous dressings with silver ions (Textus Bioactiv® by Biocell GmbH, Germany) were used. In group B hydrocolloid dressing Unna’s boot was applied. All dressings were changed every 7 days until the wound was completely healed. Changes in wound area were calculated and the speed of healing process was measured every week with healing per day index (cm2/day).Results: After 7 weeks ulcers healed in all patients of group A. Ulcers in group B healed after 16 weeks of treatment.Conclusion: On the basis of this outcome the authors concluded that application of membranous dressing with silver ions speeds up the process of treating chronic lower leg ulceration.

SummaryIntroduction: In general, four particular causes of recalcitrant venous leg ulcers may be distinguished. These are foot pump insufficiency, chronic venous compartment syndrome and non-re-canalized popliteal vein thrombosis. The fourth cause of recalcitrant venous leg ulcers is lipodermatosclerosis as a symptom of severe chronic venous insufficiency.Methods: We reviewed the literature and based on this we describe four main causes of recalcitrant venous leg ulcers and their specific treatment.Results: Foot pump insufficiency arises when the plantar foot veins are not able to empty. Treatment should consist of physical therapy, a mechanical foot pump device and an insole. Lipodermatosclerosis may be treated by excision and split-thickness skin grafting (Vigoni procedure). Chronic venous compartment syndrome is usually caused by post-thrombotic syndrome and treatment consists of a fasciectomy, but is rarely used nowadays. Patients with non-re-canalized popliteal vein thrombosis may be supported by intermittent pneumatic compression, walking exercises, alternate standing and walking with lying down. All patients with recalcitrant venous leg ulcers must wear medical elastic compression stockings with high stiffness and high compression lifelong.Conclusions: Patients with recalcitrant venous leg ulceration are challenging. More specific treatment will heal more of these ulcers.
Therapie der pudendalen Varikosis mittels Sklerosierung
Authors: Dörler M. , Stücker M. 
Published: December 2013

ZusammenfassungPudendale Varizen können als Vulvavarikose die kleinen und großen Labien, als pudendale Varikose im engeren Sinne den proximalen Oberschenkel und als perineale Varikose den Dammbereich betreffen. Sie treten besonders häufig während der Schwangerschaft auf, bilden sich aber meist schon unmittelbar post-partal zurück. Da Geburtskomplikationen durch pudendale Varizen offenbar nicht vorkommen und die Sklerosierungsmittel nicht zum Einsatz während der Schwangerschaft zugelassen sind, sollte die Sklerosierungstherapie der pudendalen Varikose außerhalb der Schwangerschaft erfolgen. Die klinische Untersuchung wird durch die Duplexsonographie der Beinvenen ergänzt. Eine weitergehende bildgebende Diagnostik der Beckenvenen ist bei Symtomen eines pelvinen Stauungssyndroms sinnvoll. Die Sklerosierung pudendaler Varizen kann bei lokalen Beschwerden und Komplikationen, bei pudendalen Varizen als Quelle einer therapiebedürftigen Varikosis des Beines und/oder aus kosmetischen Gründen indiziert sein.
Provokationsmanöver für die duplexsonographische Diagnostik der Varikose
Authors: Mendoza E. 
Published: December 2013

ZusammenfassungAnders als bei den Arterien reicht der spontane Fluss in den Beinvenen nicht für eine gute Diagnostik aus. Daher werden Provokationsmanöver zu Hilfe genommen, um einen Blutfluss zu verursachen. Klassisch kommen die Atmung und das Valsalva-Manöver zum Einsatz. In den letzten Jahren wurden dynamische und dem physiologischen Ablauf nähere Manöver entwickelt, wie das Paraná-Manöver, bei dem der Patient leicht nach vorne geschoben wird, um die Gastrocnemius-Muskulatur zu aktivieren, das Wunstorfer Manöver, bei dem der Vorfuß angehoben wird oder das Orthostase-Manöver, bei dem der Patient hingelegt und wieder aufgestellt wird, um die Schließfähigkeit der Klappen zu testen. All diese Verfahren werden vorgestellt und miteinander verglichen.

Published: December 2013

AbstractLung cancer is a major and increasing global health problem. While there have been significant advances in the understanding of lung cancer biology, still no current therapy exists to reduce the inevitable and lethal progression of this disease. Silver nanowires (AgNWs) are promising candidates for a wide range of biomedical applications and the treatment of life-threatening diseases due to their unique physico-chemical and biochemical properties. However, the safety of this nanomaterial and its use as a biomedical tool are still under debate. This study evaluates the in vitro internalisation, cytotoxicity and influence on the cell cycle of AgNWs in lung adenocarcinoma (A549) cells and lung normal fibroblasts (MRC-5 cells). Our results demonstrate that AgNWs could be internalised effectively into A549 and MRC-5 cells without inducing detectable cytotoxicity, thus providing preliminary evidence on the future potential of AgNWs as biocompatible drug delivery platforms applicable in lung cancer therapies.
The Pre- and Early Postnatal Microbiome: Relevance to Subsequent Health and Disease
Authors: Neu Josef 
Published: December 2013

With the advent of the Human Microbiome Project, wherein new high throughput technologies are employed to evaluate the taxonomy and function of microbes residing in various regions of the body, there is increasing recognition of the scope and clinical significance of the intestinal microbiota. The total number of bacterial cells residing in human intestine far exceeds the number of host cells. More than 3 million genes have been identified in this microbiota, which is more than 100-fold of our own human genes.
Although commonly thought to be related to disease as pathogens, the majority of microbes of the intestine are commensals and symbionts that benefit the host in terms of nutrition, development of the immune system, and postnatal maturation of the intestine. They perform helpful functions that cannot be performed by the human host itself.
This review aims to summarize recently emerging knowledge on the intestine microbiome in the antenatal, perinatal, and postnatal periods. We will limit our discussion to the fetal microbiome, the effects of cesarean delivery versus vaginal delivery, and the relationship of the microbiome to necrotizing enterocolitis, late-onset sepsis, and the developing brain.
LIF Imaging of OH radicals in Atmospheric DC Glow Discharge Using Miniature Gas Flow and Electrolyte Cathode
Authors: Nishiyama Shusuke , Ishigame Hiroaki , Komori Tomoki , Sasaki Koichi 
Published: December 2013

ABSTRACTIn this paper, we report the spatial distribution of OH radical density in atmospheric-pressure DC glow discharge using a miniature helium flow and an electrolyte cathode. Laser-induced fluorescence imaging was applied for the measurement of the OH radical density. The effect of collisional quenching was considered in obtaining the spatial distribution of the OH density. The spatial distribution of the OH radical density showed that the peak of the OH density was located at a separated distance from the electrolyte surface. However, the OH radicals kept contact with the electrolyte surface. It was suggested that the OH radicals were generated mainly in a region separated from the electrolyte surface and some fraction of the generated OH radicals reached to the liquid phase.
Coherence-controlled stationary entanglement between two atoms embedded in a bad cavity injected with squeezed vacuum
Authors: Liao Xiang-Ping , Fang Jian-Shu , Fang Mao-Fa 
Published: December 2013

AbstractWe investigate the entanglement between two atoms in an overdamped cavity injected with squeezed vacuum when these two atoms are initially prepared in coherent states. It is shown that the stationary entanglement exhibits a strong dependence on the initial state of the two atoms when the spontaneous emission rate of each atom is equal to the collective spontaneous emission rate, corresponding to the case where the two atoms are close together. It is found that the stationary entanglement of two atoms increases with decreasing effective atomic cooperativity parameter. The squeezed vacuum can enhance the entanglement of two atoms when the atoms are initially in coherent states. Valuably, this provides us with a feasible way to manipulate and control the entanglement, by changing the relative phases and the amplitudes of the polarized atoms and by varying the effective atomic cooperativity parameter of the system, even though the cavity is a bad one. When the spontaneous emission rate of each atom is not equal to the collective spontaneous emission rate, the steady-state entanglement of two atoms always maintains the same value, as the amplitudes of the polarized atoms varies. Moreover, the larger the degree of two-photon correlation, the stronger the steady-state entanglement between the atoms.

Published: December 2013

AbstractRhizobial lipochitooligosacharides (Nod factors) influence the development of legume roots, including growth stimulation, nodule induction and root hair curling. However, their effect on the green parts of plants is less known, therefore we evaluated seed and foliar application of an extract containing Nod factors on pea growth and yield. Pea plants were examined from emergence to full maturity, including growth dynamics and morphological (nodule number and weight, the quantity and surface area of leaves) or physiological (photosynthesis and transpiration intensity, chlorophyll and nitrogen content) parameters. The foliar application Nod factor extract, or seed dressing followed by foliar application, resulted in the best outcomes. The number and weight of root nodules, the chlorophyll content in leaves, and the intensity of net photosynthesis were all elevated. As a consequence of Nod factor treatment, the dynamics of dry mass accumulation of pea organs were improved and the pod number was increased. A significant increase in pea yield was observed after Nod factor application. Increase of nodule and pod numbers and improved growth of roots appear to be amongst the beneficial effects of Nod factor extract on the activation of secondary plant meristems.
Sodium Nitroprusside-Mediated Modulation of Growth and Antioxidant Defense in theInVitroraised Plantlets of Peanut Genotypes
Authors: Verma A. , Malik C. P. , Gupta V. K. 
Published: December 2013

ABSTRACTAs a bioactive signaling molecule, nitric oxide (NO) is involved in multiple plant physiological responses. It regulates diverse biochemical processes in a concentration-dependent manner in plants. Different NO generators viz. sodium nitroprusside (SNP), S-nitroso-N-acetyl penicillinamine (SNAP) and S-nitroso-L-glutathione (GSNO) have been reported, but SNP is the most widely used and effective NO donor. Research was conducted to investigate the in vitro effects of an NO donor, SNP, on biochemical and physiological characteristics such as multiple shoots, chlorophyll content, and enzymatic activities of superoxide dismutase (SOD), catalase (CAT), and others in Arachis hypogaea genotypes (M-13 and PBS24030). In vitro impact of SNP on shoot multiplication potential and chlorophyll content increase upto 100 µM SNP alone in peanut cultivars (M-13 and PBS24030). Rhizogenesis was noticed in the presence of SNP alone. Treatment with SNP and 6-Benzyl adenine (BA) was effective in enhancing the antioxidant enzyme activities, total soluble carbohydrates and proteins as compared to SNP alone in for both cultivars. These data indicate that in vitro establishment of peanut cultivars in the presence of SNP alone and in combination with BA will affect various growth promontory physiological and biochemical parameters. A more complete understanding of plant growth regulator (PGR) mediated responses will be instrumental in designing effective strategies for engineering crops for biotic and abiotic stresses.

Published: December 2013

Objectives We aimed to evaluate clinical outcomes and identify the predictors of mortality in elderly patients undergoing continuous ambulatory peritoneal dialysis (CAPD). Methods This retrospective cohort study included all incident CAPD patients treated at our center from 2006 to 2009. Demographic and clinical data on initiation of CAPD and clinical events during the study period were collected. Survival probabilities were generated using the Kaplan–Meier method, and risk factors for mortality were evaluated using Cox proportional hazards models. Results Of 805 patients on CAPD, the elderly group (≥65 years; mean age: 71.3 ± 4.3 years) consisted of 148 patients, and the younger group (<65 years; mean age: 43.1 ± 12.2years) consisted of 657 patients. The 1-, 2-, 3-, and 5-year patient survival rates were 97%, 92%, 88%, and 73% for the younger group, and 79%, 67%, 56%, and 30% for elderly group. The patient survival rates were significantly lower for the elderly group than for the younger group ( p = 0.000). However, technique survival did not significantly differ between the groups ( p = 0.559). In the patients overall, the independent predictors of death were old age ( p = 0.003), diabetes ( p = 0.000), cardiovascular disease ( p = 0.006), lower hemoglobin ( p = 0.010), and lower serum albumin ( p = 0.024). Mortality in the elderly patients was associated with advanced age [relative risk (RR): 1.088; 95% confidence interval (CI): 1.027 to 1.153; p = 0.004], diabetes (RR: 2.064; 95% CI: 1.236 to 3.445; p = 0.006), and lower serum albumin (RR: 0.940; 95% CI: 0.897 to 0.985; p = 0.010). Conclusions The elderly patients on CAPD experienced technique survival comparable with that of younger patients, but their patient survival was lower. In elderly patients, mortality was determined predominantly by greater age, diabetes, and lower serum albumin. Our results indicate that chronic peritoneal dialysis is a viable dialysis option for elderly patients with end-stage renal disease. Better management of hypoalbuminemia and comorbid conditions might improve survival in elderly PD patients.

Published: December 2013

Background A significant proportion of peritoneal dialysis (PD) patients receive an initial period of hemodialysis (HD) before transitioning to PD (“PD-switch”). We sought to better understand the risks of PD technique failure (TF) and mortality for those patients compared with patients starting with PD as their first dialysis modality (“PD-first”). Methods Using Canadian Organ Replacement Register data, we compared the risk of PD TF between PD-first and PD-switch patients within the first year after HD initiation. In a secondary analysis, the PD-switch patients were stratified into three groups based on timing of the switch from initial HD to PD as follows: 0 – 90 days, 91 – 180 days, and 181 – 365 days. Each group was compared with PD-first patients for risk of PD TF and death. Results Between 2001 and 2010, 9404 patients initiated PD as their first renal replacement therapy, and 3757 switched from HD to PD. After multivariable adjustment, the risk of PD TF was higher among PD-switch patients than among PD-first patients [adjusted hazard ratio (AHR): 1.37; 95% confidence interval (CI): 1.26 to 1.49], particularly within the first year after the switch from HD to PD (AHR: 1.51; 95% CI: 1.36 to 1.68). There was no association between time on HD within the first year and subsequent risk of PD TF. For all the stratified PD-switch groups, death rates were higher than those for PD-first patients. Conclusions Compared with patients who start renal replacement therapy with PD, those who transfer from HD to PD within the first year on dialysis experience higher rates of PD TF and death, with the highest risk being observed in the initial year after the switch to PD.
