Authors: Sulistianingsih Dewi , Romadhon Hendri Januar , Pujiono Pujiono
Published: April 2022

This paper aims to describe and analyze the procedure for merging cooperatives in Indonesia based on applicable regulations and the legal consequences of merging these cooperatives. Cooperative is a form of cooperation in the economic area. Cooperation in cooperatives is generally conducted under the same goal: the necessities of life. In industrialized countries, cooperatives emerged as a reaction to the system of economic freedom in the 19th century, where a group of capital owners controlled people's lives. Cooperatives in several countries have merged to increase the existence and efficiency of improving their welfare. In Indonesia, the merger of cooperatives is necessary when the cooperative wants efficiency to improve welfare. Based on the study results, it can be seen that merging cooperatives was carried out to improve the welfare of members. The act of merging cooperatives was carried out with the legal provisions in Law Number 25 of 1992. It did not use the existing rules in the Law of the Republic of Indonesia No. 11 of 2020 on Job Creation.

Objective: To study the obstetric and neonatal outcomes of reduction to singleton and twin pregnancies by multifetal pregnancy reduction (MPR) in patients with triplet pregnancies. Methods: The multifetal reduction was performed in 27 patients with triplet pregnancies. Fourteen patients were reduced to singleton pregnancies and 13 patients to twin pregnancies. Obstetric and neonatal outcomes were compared between the two groups. Results: The mean gestational age at the time of the procedure was 12.43±0.76 weeks in patients reduced to singleton pregnancies and 12.08±0.64 weeks in those reduced to twin pregnancies. The most common complications of the procedure were abdominal pain (21.4%) in women with singleton pregnancies and both the presence of abdominal pain and vaginal bleeding (30.8%) in women with twin pregnancies. Gestational age at birth (33.07±5.73 versus 35.78±6.14 weeks, p=0.009) and neonatal birth weight (1998.46±808.07 versus 2765±803.03 gram, p=0.003) was significantly higher in the group reduced to singleton pregnancies than in twin pregnancies. Conclusion: The MPR procedure is a good and acceptable option for patients with multiple pregnancies of three or more children. Multifetal pregnancy reduction of triplets to singletons is associated with better pregnancy outcomes such as birth at higher weeks of gestation and higher neonatal birth weight than MPR of triplets to twins.

Authors: Kurt Begüm , Alyazıcı Küçükyıldız İrem
Published: April 2022

Objective: We compared the first-trimester screening test results and perinatal results of pregnant women to determine the diagnosis of abruptio placentae, one of the essential causes of maternal and fetal mortality and morbidity. Methods: Between 2019 and 2021, 20 pregnant women diagnosed with abruptio placentae in our hospital and 30 pregnant women who did not develop clinical abruptio placentae during their pregnancy in the same period were included in our study. The relationship between the first-trimester screening test results and the perinatal outcomes of the patients was investigated. Results: No significant differences were found in maternal age, gravida and parity. Significant difference was found in gestational age at birth, being 33±5.1 weeks in the study group and 38.6±1.48 weeks in the control group. No statistical differences were found at PAPP-A or at b-hCG between the groups (p=0.219 and p=0.898, respectively). Nevertheless, a trend of a lower PAPP-A at the study group was noticed (1.03±0.54 MoM vs. 1.28±0.66 MoM). Significant differences were found at fetal birth weight, 1-minute Apgar score and 5-minute Apgar score. When looking at risk factors, no differences between the groups were found at smoking, multiple pregnancy, myoma uteri or diabetes, but preeclampsia and threatened preterm labor were more common at the study group. Conclusion: When we compared the first-trimester serum biomarkers to predict abruptio placentae, we could not find any significant difference between the two groups. To reach a definite conclusion on this issue, more studies with increasing the number of patients are needed.

Published: April 2022

Objective: The aim of this retrospective cohort study is to evaluate the carrier frequency of spinal muscular atrophy (SMA) among pregnant women and their partners admitted to our clinic for routine pregnancy follow-up. Methods: The study included pregnant women and their partners who were informed about SMA disease and screening at first trimester and who accepted to undergo screening for SMA. Carrier screening for SMA was carried out using DNA extracted from peripheral blood with a quantitative real-time polymerase chain reaction (qPCR) assay targeting the recurrent SMN1 exon 7-8 gene deletion. The data of the study were analyzed by SPPS version 15.0 statistical software package. Descriptive statistical analyses were carried out. Fisher’s exact test was used for intergroup comparisons. Results: The study included a total of 250 subjects, of whom 182 were female and 68 were male. The carrier frequency of SMN1 deletion was 3.6% (9/250) (95% CI: 1.66–5.54) in the entire study population, with a carrier frequency of SMN1 deletion of 1/27.8. Of 182 female participants, 6 had SMN1 deletion, with a carrier frequency of SMN1 deletion of 3.3% (95% CI: 1.3–6.2). Of 68 male participants, 3 had SMN1 deletion, with a carrier frequency of SMN1 deletion of 4.4% (95% CI: 0.35–9.4). There was no significant difference between female and male participants in terms of SMN 1 deletion frequencies (p=0.712). SMN1 duplication frequency was 8% (95% CI: 5.18–10.8) in all gender. Conclusion: The results of this study demonstrated a carrier frequency of SMN1 deletion of 1/27.7 in the Turkish population, which is higher than in many other countries. The results of the study will be useful for genetic counseling for SMA.

Published: April 2022

Objective: To present the reference range of the fetal thymus gland according to gestational age groups. Methods: In this prospective study, fetal thymus size was assessed in singleton, uncomplicated pregnancies between 19 and 38 weeks of gestation in our outpatient clinic between 2019 and 2020. Based on their monthly pregnancy follow-ups, fetal thymus measurement was divided into 5 gestational age groups (Group 1: 19–22 weeks, Group 2: 23–26 weeks, Group 3: 27–30 weeks, Group 4: 31–34 weeks, and Group 5: 35–38 weeks). Results: Fetal thymus measurements of 210 patients were performed over one year, and as a result, 184 pregnant patients were included for assessment. Fetal thymus could be visualized at a rate of 93.5%. The 5th percentile of thymus transverse diameter, antero-posterior diameter, perimeter, thymus anterior-posterior diameter to thoracic diameter, and thymus perimeter to thoracic circumference were 11.03 mm, 5.60 mm, 32.52 mm, 0.33, and 0.32 in Group 1; 13.53 mm, 7.66 mm, 43.67 mm, 0.34, and 0.32 in Group 2; 20.43 mm, 11.22 mm, 47.72 mm, 0.33, and 0.32 in Group 3; 27 mm, 12.98 mm, 55.88 mm, 0.32, and 0.30 in Group 4; 28 mm, 13.59 mm, 63.4 mm, 0.32, and 0.30 in Group 5; respectively. Spearman’s rho correlation coefficients for the thymic measurements were 0.879, 0.869, 0.846, 0.236, and 0.267 respectively, and all p-values were less than 0.001. As a result of linear regression analysis between thymus measurements and BPD; the equations for the optimal models are as follows: thymus transverse diameter= -3.49+0.4xBPD (mm) (r=0.826, R2=0.682, p<0.001), thymus anterior-posterior diameter= -2.48+0.22xBPD (mm) (r=0.808, R2=0.653, p<0.001), thymus perimeter= -14.37+1.21xBPD (mm) (r=0.814, R2=0.663, p<0.001), thymus anterior-posterior diameter /thoracic diameter= 0.38+7.76E-4xBPD (r=0.213, R2=0.045, p=0.004) and thymus perimeter/thoracic circumference= 0.35+1.02E-3xBPD (r=0.263, R2=0.069, p<0.001). Thymus transverse diameter, anterior-posterior diameter, and perimeter increased linearly with increasing biparietal diameter (BPD). Conclusion: We established the reference ranges of fetal thymus size. Thymus transverse diameter, antero-posterior diameter, and thymus perimeter have a strong relationship with gestational age and are easy and reproducible. Therefore, the knowledge of reference ranges of fetal thymus will enable the evaluation of thymic aplasia/hypoplasia.
CHIVA cure and sclerotherapy
Authors: Cappelli Massimo , Molino Lova Raffaele
Published: April 2022

Sclerotherapy is, by definition, a destructive treatment and, as such, it is conceptually long far away from the basic principles of the conservative hemodynamic cure for venous insufficiency (CHIVA cure). Accordingly, Phlebologists and Vascular Surgeons who practice the CHIVA cure at most acknowledge the use of sclerotherapy after the CHIVA cure for the aesthetical refinement or for the control over time of small calibre recurrences. However, intraoperative sclerotherapy can be used in association with the CHIVA cure in those cases in which the surgical gesture foreseen by the CHIVA cure would not be able to flush disconnect escape points at the level of the deep venous system and, as a consequence, it would leave non-draining stumps, which are a source of recurrences. Further, under some particular circumstances, sclerotherapy can be used instead of the CHIVA cure for the treatment of type II shunts or as the 1st step of the CHIVA 2 strategy for the treatment of type III shunts. This paper describes the use of intraoperative sclerotherapy for the treatment of escape points from the deep venous system difficult to treat by surgery, such as perforator veins, some anatomic presentations of the saphenous-popliteal junction and some pelvic shunts. This paper also describes the use of sclerotherapy alone for the treatment of type II shunts or for modelling saphenous hemodynamics in type III shunts before completing the treatment by surgery.

Published: April 2022

Introduction: Exfoliative cheilitis (EC) is one of the most common cheilitis found in the community. This lesion can cause difficulty in mouth opening, speech difficulties, and reduced aesthetical value of the lips. EC is a chronic inflammation characterised by desquamation, erythema, and crusting on the upper or lower lip. This study evaluated severity level, stress, and bad habit among dental students with exfoliative cheilitis. Methods: The method used in this research was descriptive with a total sampling method on the populations of dental students batch of 2016 to 2018 of the Faculty of Dentistry Universitas Padjadjaran, which obtained 83 dental students with EC. The lips were then examined, and data was recorded. EC was classified into three stages in clinical manifestation: mild, moderate, and severe exfoliative cheilitis. The data were presented with a simple frequency distribution table. Result: 30.1% of the research subjects had mild EC, 53% had moderate EC, and 16.9% had severe EC. The predisposing factors of EC in this research were stress and bad habits, where the percentage contribution were 53% and 16.9%, respectively. Students were also found with both stress and bad habits with a percentage contribution of 30.1%. Conclusions: Moderate exfoliative cheilitis is most commonly found with desquamation and erythema clinical features. The predisposing factor of exfoliative cheilitis is stress which has the highest percentage among dental students.

Published: April 2022

Introduction: People widely consume soft drinks due to their easy accessibility and delightful taste, without realising the impact on the tooth surface. Enamel dissolves easily due to acidic products that contact acid, a chemical demineralisation process (dental erosion). This study aimed to analyse the comparison between carbonated and fruit-based soft drinks effect on calcium release from enamel surface of extracted permanent teeth. Methods: In-vitro study with a time-series design was conducted on the population of extracted premolars taken from a private dental clinic and orthodontics clinic of the Faculty of Dentistry Universitas Sumatera Utara, Medan. The sample was obtained using the pairwise difference hypothesis test formula. The samples were 24 pieces divided into two treatment groups by immersing in carbonated drinks and fruit-based soft drinks for 5 to 60 minutes. The statistical test used was the independent t-test and generalised linear model-repeated measures (GLM-RM). Results: The calcium level after immersion in the carbonated drink at the fifth minute was 0.476±0.397 mg/L, then increased significantly at the sixtieth minute to 3.058±0.811 mg/L (p=0.001). In the fruit-based soft drinks immersion group, the dissolved calcium at the fifth minute was 0.671±0.208 mg/L, then increased significantly to 2.258±1.351 mg/L (p-value=0.028). Neither carbonated drinks nor fruit-based soft drinks showed a significant effect on the levels of dissolved calcium (p-value=0.135). Conclusion: In the fifth minutes of immersion, fruit-based soft drinks caused higher calcium release level compared to carbonated soft drinks. In contrast, in the sixtieth-minutes of immersion, the calcium release is found to be higher in the carbonated soft drinks group.

Published: April 2022

Introduction: Periodontitis is an inflammatory disease that destroys tooth-supporting tissues and is associated with increased risk factors for systemic diseases. The main pathogen of periodontitis is the bacteria P. gingivalis, a Gram-negative, anaerobic, pleomorphic, coccobacillus, non-motile, and saccharolytic. The leaves of Indian jujube (Ziziphus mauritiana Lam.) have the main bioactive compounds such as saponins, tannins, and flavonoids which have antimicrobial activities against pathogenic microorganisms. This study aims to analyse various concentrations of the ethanol extract of Indian jujube leaves against P. gingivalis. Methods: The method used in this study was the disc diffusion test based on the Clinical and Laboratory Standard Institute. P. gingivalis preparation and the fresh leaves of Indian jujube collected from one of the plantations in Probolinggo, East Java. In this study, tests used various concentrations of Indian jujube leaves extract, namely 10, 20, 30, 40, 50, 60, 70, 80, 90, and 100%. Data antibacterial activity was classified according to David and Stout’s inhibition zone classification. Results: Indian jujube leaves extract with a concentration between 10-30% had weak antibacterial activity, 40-60% had moderate antibacterial activity, and 70-100% had strong antibacterial activity. The largest inhibitory zone diameter against P. gingivalis was found at a concentration of 100%. Conclusion: Indian jujube leaves extract starting from a concentration of 70% can inhibit the growth of P. gingivalis with strong antibacterial activity.

A Biomimetic Approach to Protective Glove Design: Inspirations from Nature and the Structural Limitations of Living Organisms
Authors: Irzmańska Emilia , Jastrzębska Aleksandra , Michalski Marek
Published: April 2022

Drawing inspiration from nature for the design of new technological solutions and smart materials constitutes an important development area for engineers and researchers in many disciplines. Biomimetic materials design brings numerous benefits, especially the possibility of implementing promising interdisciplinary projects based on effective existing solutions that have emerged in the course of natural evolution.

A major aspect of biomimetic materials design, especially relevant to protective gloves, is the identification of an optimum combination of the physicochemical properties and microstructural characteristics of a surface with a view to its potential applications. Properties such as wetting and adhesion can be adjusted by modifications of the surface morphology both on micro- and nanoscales. From the standpoint of the occupational safety performance of polymeric protective gloves, biomimetic materials should exhibit two crucial properties: reversible adhesion (via a large number of contact points) and hydrophobicity (water repellence).

This review analyzes the superhydrophobic and reversible adhesion patterns found in nature that can be used to improve the properties of polymeric protective gloves with major commercial implications.
Prevalence of left atrial septal pouch among patients with embolic stroke of undetermined source or stroke of known etiology: A retrospective study
Authors: Steyaert Hugo , Castro Rodriguez Jose , Gazagnes Marie-Dominique , Morissens Marielle
Published: April 2022

Background and objectives

Cryptogenic strokes can be defined by the criteria established for an embolic stroke of undetermined source (ESUS). Some embolic events might be caused by a left atrial septal pouch (LASP), due to the potential of thrombus formation. In this study we aimed to determine if LASP is a risk factor for ESUS when compared to a population of strokes of known origin, the LASP screening rate in our institution and if LASP dimensions influences the risk of ESUS.

Methods

We retrospectively analyzed transesophageal echocardiograms (TEEs) in a large cohort of patients that had experienced ischemic strokes. Two authors performed blinded, independent searches for LASPs by reviewing 1152 TEEs from patients that had experienced a stroke or transient ischemic attack. We excluded 26 TEEs, due to incorrect imaging. Next, we reviewed patient medical files.

Results

Among the 1126 included patients, 148 had an ESUS (ESUS+ group) and 978 had strokes of known origin (ESUS– group). A LASP was present in 176 patients, including 32 patients (21.6% of LASPs) in the ESUS+ group and 144 patients (14.7% of LASPs) in the ESUS– group. In multivariate analysis, LASP was independently associated with ESUS (P = 0,019). 61.9% of LASPs that we found were not mentioned in reports from the original TEE operators.

Conclusion

This study demonstrated that LASPs were more prevalent in patients with ESUS than in patients with strokes of known origin. Our results gave rise to the question of whether anticoagulation would be appropriate for some patients with ESUS. New large-scale, prospective studies should be conducted to address this issue. Additionally, considering the low rate of LASP descriptions, we concluded that the awareness of operators should be raised to improve their success in identifying LASPs.

Metaphors for Anatomy Lesson of Students Who Received Anatomy Education in Faculty of Medicine and Faculty of Dentistry
Authors: ÇAN Mehmet Ali
Published: April 2022

Aim: Metaphor, which is used to mean "to describe one thing with another thing", is the explanation of certain situations, concepts and phenomena with other well-known expressions. Metaphor, which is generally considered by linguists as a rhetoric to embellish discourse, but is mostly used in the field of education and is the subject of research, is also one of the methods that can be used in reaching information. Anatomy courses given in institutions providing education in the field of health are one of the basic courses and take up a very large place in the first years of education. For this reason, the opinions of the students who receive education are important. In this study, it is aimed to investigate the thoughts and interpretations of the students of the faculty of medicine and dentistry about the Anatomy course through metaphors.Methods: A questionnaire consisting of four questions was applied online to the students of Çanakkale Onsekiz Mart University Faculty of Medicine and Faculty of Dentistry, who agreed to participate in the study after the approval of the ethics committee, and the answers were evaluated qualitatively.Results: As a result of the data collection period between March 2021 and May 2021, a total of 134 students, 74 from the Faculty of Dentistry and 60 from the Faculty of Medicine, participated in the stud by giving their consent for the study. Of the participants in the study, 82 were female and 52 were male. While 38.8% of the students had positive opinions about the Anatomy course, 61.2 of them had negative opinions. 81.3% of the students expressed the Anatomy lesson with a concrete concept and 18.7% with an abstract concept. 14.2% of the concepts paired with anatomy are related to health, and 85.8% are unrelated to the field of health. 33.7% of the expressions were classified as object, 24.6% as action, 17.9% as situation, 13.4% as place and 10.4% as concept.Conclusions: According to our observations as a result of the research, Anatomy course creates a great burden on students studying in dentistry and medical faculties and becomes a source of stress. In addition, most of the students stated that the course is important. In the light of these data, it has been concluded that it is necessary to make anatomy lessons more attractive to students, to avoid unnecessary information and details, to provide information that they will use in their professional lives, to increase interest by associating the course topics with clinical situations.

Aim: Anatomy is the basis for the professional education of nursing and paramedic students. This study was conducted to determine nursing and paramedic students' attitudes towards the anatomy courseproviding through distance learning system and self-efficacy perceptions towards online technologies. Methods: This study, which was a cross-sectional study, was conducted at Bartin University between February 25, 2021 and March 01, 2021, following the end of the 2020-2021 Academic Year, FallSemester. A total of 245 students participated in the study and the participation rate was 65%. A Descriptive Information Form, Anatomy Attitude Scale and the Online Technologies Self-Efficacy Scalewere used to collect the data. Results: Almost half of the participants were nursing students and 69.60% of them were women. Majority of students stated that course content was sufficient. Over the half of the participants stated that theoretical course hours and the laboratory hours were sufficient. A quarter of of the students demands more visual material to be used during the lessons. The content of anatomy and studying methodaffected students' attitudes towards anatomy courses. Additionally, studying method of anatomy affected the perception of self-efficacy towards online technologies. A weak but significant relationship was found between the Attitude Scale Towards Anatomy Course and the Self-Efficacy Scale Towards Online Technologies.Conclusions: As a result of the present study, it has been revealed that adapting the content of anatomy course and learning methods to the distance learning and increasing the technological competence ofnursing and paramedic students is important to make the anatomy course interesting and increase the learning levels of the students. In future studies, it is recommended to develop and test new teachingmethods to improve students' competencies for online technologies, as well as their positive attitudes towards the anatomy course providing through distance learning system.

Published: April 2022

Aim: In this study on physicians who graduated at 2000 and after, contribution of the pathology education they received in medical faculties to their active professional lives, its adequacy and necessity, and their opinions and suggestions were examined.Methods: An open-ended, multiple choice and Likert scale format digital questionnaire consisting of 12 questions was filled by the consenting physicians who graduated in 2000 and later.Results: Total 107 physicians (39 (36.4%) clinical, 38 (35.5%) surgical sciences and 30 (28%) general practitioners) participated in the study. Forty-one physicians (38%) took the pathology course only in the third year. Didactic training was most frequently accompanied by microscopy (n = 94, 87.9%) training. Sixty-six (61.68%) physicians additionally received macroscopy training. Pathology education was very useful and beneficial for their current professional life for 75% physicians and was very sufficient and quite sufficient in 45% physicians. There was a statistically significant relationship between the benefit of pathology in professional life and the adequacy of the education received (p = 0.01). The usability of the knowledge (n = 89, 83.2%), the educational methods (n = 78, 72.9%), and the characteristics of the educator (n = 75, 70.1%) were rated as the most important factors for its benefit in active professional life. Case discussions (n= 79, 72.9%), macroscopy (n = 65, 60.7%), and microscopy laboratory study (n= 62, 57.9%), problem-based learning (PBL) (n = 61, 57.0%), and observation in hospital laboratory ( n= 51, 47.6%) are recommended besides objective structured practical exam (OSPE) (n = 85, 79.4%) andobjective structured clinical exam (OSCE) (n = 76, 71.0%). Conclusions: Pathology education will be helpful in active professional life if the curriculum is usable, integrated with the clinic and delivered with diversified up-to-date learning methods. The benefit of pathology education increases in parallel to its adequacy. Also, surgical and internal sciences physicians benefit more than practitioners. It would be appropriate to set up-to-date standards on the years, duration, content and method of pathology education.

Authors: Hafner Andreas , Van Der Schaaf Paul A. , Miihlebach Andreas
Published: April 2022

Properties and applications of newly developed homogeneous Ring-Opening Metathesis Polymerization catalysts as well as Photo-induced Ring-Opening Metathesis Polymerization catalysts are discussed. In contrast to well-defined, one-component metal-carbene catalysts, the aqueous ROMP with simple RuII salts is a chain reaction and not a living polymerization. One-component Photo-ROMP initiators were developed with good thermal latency and are either based on early-transition-metal alkyl complexes or on [Ru(arene)2]2+ complexes. Mechanistic aspects of the photochemically induced solvation of RuII complexes are presented.

From efforts to improve the biophysical properties of antisense oligonucleotides by incorporating backbone- or sugar-modified nucleoside analogs, 2'-O-methoxyethyl ribonucleosides 8b were identified as building blocks for a second generation of antisense oligonucleotides. Compounds containing these modifications were demonstrated to combine the benefit of a high binding affinity to the RNA complement with a large increase in nuclease resistance, allowing the use of regular phosphodiester linkages. Chimeric oligonucleotides with 2'-O-methoxyethyl ribonucleosides, 8b, in the wings and a central DNA-phosphorothioate window were shown to efficiently downregulate C-'raf' kinase and PKC-α messenger-RNA in tumor cell lines resulting in a profound inhibition of cell proliferation. The same compounds were able to effectively reduce the growth of tumors in animal models at low concentrations indicating the potential utility of these second generation antisense oligonucleotides for therapeutic applications.

Change of shape, size and form related to traditional and new materials in Atoni buildings in Central Timor
Authors: Zamolyi Ferenc
Published: April 2022

This article is the second part of the analysis of the author´s field research, which was conducted in Timor in May 2004 in Maubesi, and in June 2011 near Soe and Nikiniki and Kefamenanu. The paper focuses on the region of Central Timor, settled by the Atoni Meto people, who live in round houses built on the ground. The house form and materials utilised differ somewhat in the higher regions of Central Timor and the lower-lying Eastern parts of Central Timor. The aim of this article is to explore how such building materials are utilised and whether they are or can be integrated into local vernacular building traditions. New materials are often used to imitate the more traditional ones, often incorporating structural details from the older technology and traditional materials which are copied. In other cases, new materials lead to a change in the appearance and structure of vernacular buildings. New materials already influencing the building due to their different, new properties, and designs are devised to adapt to these changes, which in the end result in an altered building. It appears that the highland regions of Central Timor near Soe and Nikiniki use a more conservative house design while in the region around Kefamenanu modern materials are more present in vernacular architecture. The use of concrete and corrugated iron to build lopos (traditional granaries and community buildings) is striking and has produced a new version of the traditional lopo.
The Absorption of Phosphonium Cations and Dications into a Hydrated POPC Phospholipid Bilayer: a Computational Study
Authors: Pillai Visakh , Kumari Pallavi , Benedetto Antonio , Gobbo Dorothea , Ballone Pietro
Published: April 2022

Molecular dynamics (MD) based on an empirical force field is applied to investigate the effect of phosphonium cations ([P 6,6,6,6 ] + ) and geminal dications ([DxC10] 2+ ) inserted at T = 300 K into the hydration layer separating planar POPC phospholipid bilayers. Up to high concentration, nearly every added cation and dication becomes absorbed into the lipid phase. Absorption takes place during several µs and is virtually irreversible. The neutralising counterions ([Cl] − , in the present simulation) remain dissolved in water, giving origin to charge separation and strong electrostatic double layer at the water/lipid interface. Incorporation of cations and dications changes properties of the lipid bilayer such as diffusion, viscosity and electrostatic pattern. At high ionic concentration, the bilayer acquires a long-wavelength standing undulation, corresponding to a change of phase from fluid planar to ripple. All these changes are potentially able to affect processes relevant in the context of cell biology. The major difference between cations and dications concerns the kinetics of absorption, that takes place nearly two times faster in the [P 6,6,6,6 ] + case, and for [DxC10] 2+ dications displays a marked separation into two-stages, corresponding to the easy absorption of the first phosphonium head of the dication, and the somewhat more activated absorption of the second phosphonium head of each dication.
