Abstract
The early evolution of a supernova (SN) can reveal information about the environment and the progenitor star. When a star explodes in vacuum, the first photons to escape from its surface appear as a brief, hours-long shock-breakout flare1,2, followed by a cooling phase of emission. However, for stars exploding within a distribution of dense, optically thick circumstellar material (CSM), the first photons escape from the material beyond the stellar edge and the duration of the initial flare can extend to several days, during which the escaping emission indicates photospheric heating3. Early serendipitous observations2,4 that lacked ultraviolet (UV) data were unable to determine whether the early emission is heating or cooling and hence the nature of the early explosion event. Here we report UV spectra of the nearby SN 2023ixf in the galaxy Messier 101 (M101). Using the UV data as well as a comprehensive set of further multiwavelength observations, we temporally resolve the emergence of the explosion shock from a thick medium heated by the SN emission. We derive a reliable bolometric light curve that indicates that the shock breaks out from a dense layer with a radius substantially larger than typical supergiants.

Abstract
Background Tyrosine kinase inhibitors (TKIs) have significantly lowered mortality of chronic myeloid leukemia (CML) patients adjusting life expectancy to that of the standard population. However, CML and its treatment with TKIs causes a high disease burden. Physical exercise (PE) could be a non-pharmacological approach to reducing these and improving quality of life. Purpose The aim of this study was to determine the individual disease burden as well as PE preferences of CML patients and to deduce thereof specific PE recommendations. Methods This multicenter survey was conducted in cooperation with the LeukaNET/Leukemia-patient network including CML patients aged ≥18 years (German Registry of Clinical Trials, DRKS00023698). The severity of selected symptoms was assessed using the adapted Myeloproliferative Neoplasms Symptom Assessment Form: 0 (absent), 1-30 (mild), 31-70 (moderate), or 71-100 (severe). Information about patients' PE needs and preferences depending on their motivation was recorded. Results A total of 212 questionnaires were analyzed (52% female, median age 54 years). The prevalence of moderate-to-severe symptoms was 49% for fatigue, 40% for musculoskeletal pain, and 37% for concentration problems. Other commonly reported symptoms included skin reactions (42%) and weight gain (24%). The proportion of overweight/obese patients was 52%. Half of all respondents requested more information regarding PE. Patients with CML preferred individual training (82%), located outdoors (71%), at home (47%), or in an indoor swimming pool (31%). Regarding the training frequency, sports-inactive patients preferred a frequency of 1-2 training sessions per week, whereas sports-active patients preferred 3-4 sessions per week (p <0.001). Sports-inactive patients preferred a training time of 15-45 minutes, while sports-active patients preferred 30-60 minutes (p = 0.002). Subsequently, PE recommendations were developed for patients with CML. Combined resistance and endurance training (moderate intensity twice per week for 30 minutes) was recommended for beginners. Obese patients should prioritize joint-relieving sports. To reduce the risk of skin reactions, direct sunlight and possibly water sports should be avoided, and UV protection should be used. Conclusion Counseling and motivation of CML patients to be physically active should be part of the standard of care as well as support for implementation.

Abstract
BACKGROUND Exercise therapy during cancer treatment reduces symptom burden and improves quality of life (QoL). Polycythemia vera (PV) is a myeloproliferative neoplasia associated with good overall survival (up to decades) but a significant symptom burden, including thromboembolic events and dysesthesias. There are no specific exercise recommendations for patients with PV. Thus, we aimed to determine the exercise preferences of patients with PV and to derive specific recommendations based on the most commonly reported symptoms. METHODS This multicenter survey included patients with PV ≥18 years old. Demographic, clinical, and disease burden data were collected. The severity of selected symptoms was assessed using the adapted Myeloproliferative Neoplasms Symptom Assessment Form: 0 (absent), 1-30 (mild), 31-70 (moderate), or 71-100 (severe). The patients' information needs about physical activity (PA) and exercise preferences were recorded depending on their motivation and analyzed with regard to demographic aspects. RESULTS The sample comprised 182 patients (68% female, 61 ± 12 years). The prevalence of moderate-to-severe symptoms was 60% for fatigue, 44% for concentration problems, and 35% for bone/muscle pain. Other commonly reported symptoms included skin reactions (49%), splenomegaly (35%), and increased bleeding tendency (28%). Overall, 67% of respondents requested more information regarding PA. Patients with PV preferred individual training (79%) located outdoors (79%) or at home (56%). Regarding the amount of training, sports-inactive patients preferred a frequency of 1-2 times/week and session durations of 15-45 min, whereas sports-active patients preferred 3-4 times/week and 30-60 min (p < 0.001). Higher sport-inactiveness was observed in patients with lower educational level compared to patients with higher educational level (69% vs. 50%, p = 0.021). For beginners, combined resistance-endurance (circuit) training two times/week, which can be performed outdoors or at home, should be recommended. In the case of splenomegaly or bleeding symptoms, exercises with a low injury risk should be chosen. CONCLUSION PA is important for patients with PV; therefore, counseling should be integrated into the treatment plan. Specifically, patients with low educational level should be addressed. Prospective studies are warranted to evaluate the effects of the novel exercise recommendations.

Abstract
Peripheral T-cell lymphomas (PTCLs), especially angioimmunoblastic and follicular TCLs, have a dismal prognosis because of the lack of efficient therapies, and patients' symptoms are often dominated by an inflammatory phenotype, including fever, night sweats, weight loss, and skin rash. In this study, we investigated the role of inflammatory granulocytes and activated cytokine signaling on T-cell follicular helper-type PTCL (TFH-PTCL) disease progression and symptoms. We showed that ITK-SYK-driven murine PTCLs and primary human TFH-PTCL xenografts both induced inflammation in mice, including murine neutrophil expansion and massive cytokine release. Granulocyte/lymphoma interactions were mediated by positive autoregulatory cytokine loops involving interferon gamma (CD4+ malignant T cells) and interleukin 6 (IL-6; activated granulocytes), ultimately inducing broad JAK activation (JAK1/2/3 and TYK2) in both cell types. Inflammatory granulocyte depletion via antibodies (Ly6G), genetic granulocyte depletion (LyzM-Cre/MCL1flox/flox), or IL-6 deletion within microenvironmental cells blocked inflammatory symptoms, reduced lymphoma infiltration, and enhanced mouse survival. Furthermore, unselective JAK inhibitors (ruxolitinib) inhibited both TCL progression and granulocyte activation in various PTCL mouse models. Our results support the important role of granulocyte-driven inflammation, cytokine-induced granulocyte/CD4+ TCL interactions, and an intact JAK/STAT signaling pathway for TFH-PTCL development and also support broad JAK inhibition as an effective treatment strategy in early disease stages.

Abstract
In order to elucidate mechanisms for SARS-CoV-2 vaccination success in hematological neoplasia, we herein provide a comprehensive characterization of the spike-specific T-cell and serological immunity induced in 130 patients in comparison to 91 healthy controls. We studied 121 distinct T-cell subpopulations and the vaccination schemes as putative response predictors. In patients with lymphoid malignancies an insufficient IgG response was accompanied by a normal CD4+ T-cell function. Compared to controls, a spike-specific CD4+ response was detectable in fewer patients with myeloid neoplasia whereas the seroconversion rate was normal. In-depth immunophenotyping demonstrated in particular, that CD4+ T-cells and naïve CD4+ T-cells were reduced in both patient cohorts without differences between the groups. Vaccination-induced CD4+ responses were associated to CD8+ and IgG responses. Vector-based AZD1222 vaccine induced more frequently detectable specific CD4+ responses in study participants across all cohorts (27/28, 96%), whereas fully mRNA based vaccination schemes resulted in measurable CD4+ cells in 102/168 participants only (61%, p<0.0001). A similar benefit of vector-based vaccination was observed for the induction of spike-specific CD8+ T-cells. Multivariable models confirmed vaccination schemes that incorporated at least one vector-based vaccination as key feature to mount both a spike-specific CD4+ (odds ratio 10.67) and CD8+ response (odds ratio 6.56). Multivariable analyses identified a specific CD4+ response, but not the vector-based immunization as beneficial for a strong specific IgG titer. Our study reveals factors associated with a T-cell response in patients with hematologic neoplasia and might pave the way towards tailored vaccination schemes for vaccinees suffering from these diseases. The study is registered at the German Clinical Trials Register (DRKS00027372).

Abstract
Background Physical activity (PA) is a non-pharmacological approach to alleviate symptom burden and improve health-related quality of life (HrQoL) in cancer patients (pts). Whether pts with myeloproliferative neoplasms (MPN) PA behavior changes due to symptom burden and/or knowledge of the putative beneficial effects of PA has not yet been investigated. Methods We performed a large questionnaire study in MPN pts. Self-reported PA behavior and potential influencing factors of 634 MPN pts were analyzed. Questionnaires were used to assess demographics, anxiety, severity of symptoms, HrQoL, current level of everyday and sports activities, and the level of information regarding the importance/possibilities of PA. According to their PA, the pts were assigned to the three groups: "inactive", "non-targeted active", and "sporty active" and compared with each other. Results Key findings are that in 73% of the pts, the disease had an impact on PA, with 30% of pts reducing their PA. The prevalence of anxieties (e.g., occurrence of thrombosis and bleeding) regarding PA was 45%. Sporty active pts had a lower symptom burden and better HrQoL (p ≤ 0.001) compared to the other groups. Inactive pts were significantly older and had a higher body mass index than sporty active pts. Inactive and non-targeted active pts felt less informed about the importance/possibilities of PA (p = 0.002). Conclusion Our results suggest that especially older and non-sporty MPN pts could benefit from motivational as well as disease-specific PA information. This study was registered at the German Registry of Clinical Trials, DRKS00023698.

Abstract
OBJECTIVE This study retrospectively examined the association between cancer-related fatigue (CrF) and the number of falls during the last 12 months in patients with myeloproliferative neoplasms (MPNs). METHODS A multicenter, 1-time anonymous survey was conducted using analog and digital questionnaires. Sex-stratified multinomial logistic regression analysis was applied to investigate the association between CrF and number of falls. All analyses were adjusted for age, school education, body mass index, MPN subtype, and quality of life. RESULTS The final sample comprised 688 patients (mean age 57.4 ± 13.8, 62.4% women). The fall rate was 16.2% in women and 12.2% in men (P = .153). There were no differences between women and men in terms of CrF between individuals with more than 1 fall, whereas women with 1 fall had a higher CrF compared to those without a fall (RRR = 1.019; 95% CI [1.002-1.039]), respectively. CONCLUSION CrF increases the risk of falls in women with MPN. Physicians should evaluate and manage CrF symptoms and implement fall prevention strategies for those who are at increased risk. Further research is needed to better understand the effects of CrF on gait performance and associated fall risk.

Abstract
Purpose: To assess humoral responses longitudinally and cellular immunogenicity following SARS-CoV-2-vaccination in patients with hematologic and oncologic malignancies receiving checkpoint-inhibitors. Methods: This prospective multicenter trial of the East-German-Study-Group-for-Hematology-and-Oncology, enrolled 398 adults in a two (patients; n = 262) to one (controls; n = 136) ratio. Pre-vaccination, day 35 (d35), and day 120 (d120) blood samples were analyzed for anti-spike antibodies and d120 IL-2+IFNγ+TNFα+-CD4+- and CD8+-cells. Laboratories were blinded for patients and controls. Results: Patients belonged to the myeloid (n = 131), lymphoid (n = 104), and checkpoint-inhibitor (n = 17) cohorts. While d35 seroconversion was higher in controls (98%) compared to patients (68%) (p < 0.001), d120 seroconversion improved across all patient cohorts [checkpoint-inhibitors (81% to 100%), myeloid (82% to 97%), lymphoid (48% to 66%)]. CD4+- and CovCD8+-cells in the lymphoid (71%/31%) and control (74%/42%) cohorts were comparable but fewer in the myeloid cohort (53%, p = 0.003 /24%, p = 0.03). In patients with hematologic malignancies, no correlation between d120 humoral and cellular responses was found. A sizeable fraction of lymphoid patients demonstrated T-cell responses without detectable spike-specific-IgGs. Conclusions: Evidence of vaccine-elicited humoral and/or cellular immunogenicity in most patients is provided. Both humoral and cellular responses are crucial to determine which patients will generate/maintain immunity. The findings have implications on public health policy regarding recommendations for SARS-CoV-2 booster doses.

Abstract
The final fate of massive stars, and the nature of the compact remnants they leave behind (black holes and neutron stars), are open questions in astrophysics. Many massive stars are stripped of their outer hydrogen envelopes as they evolve. Such Wolf-Rayet stars1 emit strong and rapidly expanding winds with speeds greater than 1,000 kilometres per second. A fraction of this population is also helium-depleted, with spectra dominated by highly ionized emission lines of carbon and oxygen (types WC/WO). Evidence indicates that the most commonly observed supernova explosions that lack hydrogen and helium (types Ib/Ic) cannot result from massive WC/WO stars2,3, leading some to suggest that most such stars collapse directly into black holes without a visible supernova explosion4. Here we report observations of SN 2019hgp, beginning about a day after the explosion. Its short rise time and rapid decline place it among an emerging population of rapidly evolving transients5-8. Spectroscopy reveals a rich set of emission lines indicating that the explosion occurred within a nebula composed of carbon, oxygen and neon. Narrow absorption features show that this material is expanding at high velocities (greater than 1,500 kilometres per second), requiring a compact progenitor. Our observations are consistent with an explosion of a massive WC/WO star, and suggest that massive Wolf-Rayet stars may be the progenitors of some rapidly evolving transients.

Abstract
OBJECTIVE To compare the neonatal and maternal outcomes as well as the mode of delivery of intended vaginal breech deliveries in women with a prior cesarean section to primiparous patients. STUDY DESIGN The prospective monocenter cohort study was conducted among 604 women who presented for an intended vaginal singleton breech delivery at term between January 2007 and December 2016. RESULTS Out of 37 women with a prior cesarean 19 had a successful vaginal delivery. 344 of 567 primiparous women had a successful vaginal delivery. Neonatal morbidity and mortality as well as maternal outcome were not significantly different in successful vaginal deliveries of women with prior cesarean compared to primiparous patients. The cesarean section rate was not significantly higher in the group of women with a prior cesarean (49%) compared to the group of primipara (39%). CONCLUSION A prior cesarean should not be taken as an exclusion criterion for a planned vaginal delivery out of a breech presentation at term. Large multicenter, case-controlled studies are necessary to implement international guidelines.

Abstract
Motivation In the new release of pymzML (v2.0), we have optimized the speed of this established tool for mass spectrometry data analysis to adapt to increasing amounts of data in mass spectrometry. Thus, we integrated faster libraries for numerical calculations, improved data retrieving algorithms and have optimized the source code. Importantly, to adapt to rapidly growing file sizes, we developed a generalizable compression scheme for very fast random access and applied this concept to mzML files to retrieve spectral data. Results pymzML performs at par with established C programs when it comes to processing times. However, it offers the versatility of a scripting language, while adding unprecedented fast random access to compressed files. Additionally, we designed our compression scheme in such a general way that it can be applied to any field where fast random access to large data blocks in compressed files is desired.

Abstract
Sequential genotyping for phenotype-driver mutations in JAK2 (exon 14), CALR (exon 9), and MPL (exon 10) is recommended in patients with myeloproliferative neoplasms. Yet, atypical JAK2- and MPL-mutations were described in some triple-negative patients. Whether noncanonical and/or concomitant JAK2- and MPL-mutations exist in myelofibrosis (MF) regardless of phenotype-driver mutations is not yet elucidated. For this, next-generation sequencing (NGS) was performed using blood genomic DNA from 128 MF patients (primary MF, n = 93; post-ET-MF, n = 18; post-PV-MF, n = 17). While no atypical JAK2- or MPL-mutations were seen in 24 CALR-positive samples, two JAK2-mutations [c.3323A > G, p.N1108S; c.3188G > A, p.R1063H] were detected in two of the 21 (9.5%) triple-negative patients. Twelve of the 82 (14.6%) JAK2V617F-positive cases had coexisting germline JAK2-mutations [JAK2R1063H, n = 6; JAK2R893T, n = 1; JAK2T525A, n = 1] or at least one somatic MPL-mutation [MPLY591D, n = 3; MPLW515 L, n = 2; MPLE335K, n = 1]. Overall, MPL-mutations always coexisted with JAK2V617F and/or other MPL-mutations. None of the JAK2V617F plus a second JAK2-mutation carried a TET2-mutation but all patients with JAK2V617F plus an MPL-mutation harbored a somatic TET2-mutation. Four genomic clusters could be identified in the JAK2V617F-positive cohort. Cluster-I (10%) (noncanonical JAK2mutated (mut) + TET2wildtype (wt) ) were younger and had less proliferative disease compared with cluster-IV (5%) (TET2mut + MPLmut ). In conclusion, recurrent concomitant classical and/or noncanonical JAK2- and MPL-mutations could be detected by NGS in 15.7% of JAK2V617F- and MPLW515-positive MF patients with genotype-phenotype associations. Many of the germline and/or somatic mutations might act as "Significantly Mutated Genes" contributing to the pathogenesis and phenotypic heterogeneity. A cost-effective NGS-based approach might be an important step towards patient-tailored medicine.

Abstract
Long γ-ray bursts are associated with energetic, broad-lined, stripped-envelope supernovae1,2 and as such mark the death of massive stars. The scarcity of such events nearby and the brightness of the γ-ray burst afterglow, which dominates the emission in the first few days after the burst, have so far prevented the study of the very early evolution of supernovae associated with γ-ray bursts3. In hydrogen-stripped supernovae that are not associated with γ-ray bursts, an excess of high-velocity (roughly 30,000 kilometres per second) material has been interpreted as a signature of a choked jet, which did not emerge from the progenitor star and instead deposited all of its energy in a thermal cocoon4. Here we report multi-epoch spectroscopic observations of the supernova SN 2017iuk, which is associated with the γ-ray burst GRB 171205A. Our spectra display features at extremely high expansion velocities (around 115,000 kilometres per second) within the first day after the burst5,6. Using spectral synthesis models developed for SN 2017iuk, we show that these features are characterized by chemical abundances that differ from those observed in the ejecta of SN 2017iuk at later times. We further show that the high-velocity features originate from the mildly relativistic hot cocoon that is generated by an ultra-relativistic jet within the γ-ray burst expanding and decelerating into the medium that surrounds the progenitor star7,8. This cocoon rapidly becomes transparent9 and is outshone by the supernova emission, which starts to dominate the emission three days after the burst.

Abstract
The introduction of colloidal single-layer carbon nitride (SLCN) nanosheets at the stage of the formation of Au nanocrystals (NCs) in aqueous solutions allows the surface plasmon resonance peak position of gold/SLCN composites to be tuned in a relatively broad range of 520–610 nm. The effect is believed to originate from a strong electronic interaction between Au NCs and SLCN nanosheets attached to their surface as capping ligands and resulting in a decrease of the effective electron density on the Au NC surface. The SLCN nanosheets suppress direct interparticle interactions between Au NCs prohibiting additional plasmonic features typical for the Au NC associates. Species similar to SLCN in terms of functionalities but having no conjugated aromatic system, such as polyethyleneimine, only induce aggregation of Au NCs but do not allow the main surface plasmon resonance of the NCs to be tuned demonstrating the crucial role of electronic interaction between the NC surface and the aromatic SLCN sheets for the surface plasmon resonance tuning. Interaction of forming Au nanocrystals with single-layer carbon nitride nanosheets allows the surface plasmon resonance peak position of gold/carbon nitride composites to be tuned in a range of 520–610 nm.![]()

Abstract
The ReLEx® technique allows correction of refractive errors through the creation and extraction of refractive stromal lenticules. Contrary to excimer laser corneal refractive procedures, where the stromal tissue is photoablated, the extracted lenticules obtained with ReLEx® can be preserved. Recent studies and case reports have described autologous re-implantation and allogeneic implantation of refractive lenticules into femtosecond-laser created stromal pockets in order to reverse the refractive outcome of a myopic corneal refractive procedure, correct hyperopia, aphakia, presbyopia and treat keratoconus. The use of stromal lenticules has also been described for therapeutic purposes, with an allogenic lenticule being transplanted under a LASIK flap in order to restore corneal volume and reduce the refractive error in a case of excessive stromal tissue removal after LASIK. This review summarises the results of the latest case reports and studies that describe the implantation of cryopreserved or fresh refractive stromal lenticules and discusses the feasibility, safety and refractive outcomes of the procedure, on the basis of published literature as well as our own experience.

Abstract
Good quality, complementary-metal-oxide-semiconductor (CMOS) technology compatible, 200 mm graphene was obtained on Ge(001)/Si(001) wafers in this work. Chemical vapor depositions were carried out at the deposition temperatures of 885 °C using CH4 as carbon source on epitaxial Ge(100) layers, which were grown on Si(100), prior to the graphene synthesis. Graphene layer with the 2D/G ratio ∼3 and low D mode (i.e., low concentration of defects) was measured over the entire 200 mm wafer by Raman spectroscopy. A typical full-width-at-half-maximum value of 39 cm-1 was extracted for the 2D mode, further indicating that graphene of good structural quality was produced. The study also revealed that the lack of interfacial oxide correlates with superior properties of graphene. In order to evaluate electrical properties of graphene, its 2 × 2 cm2 pieces were transferred onto SiO2/Si substrates from Ge/Si wafers. The extracted sheet resistance and mobility values of transferred graphene layers were ∼1500 ± 100 Ω/sq and μ ≈ 400 ± 20 cm2/V s, respectively. The transferred graphene was free of metallic contaminations or mechanical damage. On the basis of results of DFT calculations, we attribute the high structural quality of graphene grown by CVD on Ge to hydrogen-induced reduction of nucleation probability, explain the appearance of graphene-induced facets on Ge(001) as a kinetic effect caused by surface step pinning at linear graphene nuclei, and clarify the orientation of graphene domains on Ge(001) as resulting from good lattice matching between Ge(001) and graphene nucleated on such nuclei.

Abstract
Background The aim of this clinical trial was to check the results of laser built-in settings 3 years after ReLEx SMILE for moderate and high myopia in unselected "real life" patients. Patients and Methods 50 myopic eyes of 27 patients were called in for examination after 3 years. 25 of these eyes with a preoperative myopia under - 6D comprised the "moderate myopia subgroup". All surgeries were performed with the 500 kHz VisuMax® femtosecond laser (Carl Zeiss Meditec AG, Jena) in the "fast mode" setting. Results The spherical equivalent (SE) of the entire group changed from - 6.18 D (± 1.91) prior to surgery to - 0.18 D (± 0.39) 3 years later. The preoperative SE in the moderate myopia subgroup changed from - 4.71 D (± 0.94) to - 0.04 D (± 0.23). 14 % of 50 eyes gained one line and 22 % lost one line of CDVA. The regression between month 3 and 36 was 0.07D for the entire group and 0.06 D for the moderate myopia subgroup. There were no late side effects. Primary undercorrection was predominantly seen in eyes over - 6 D. Conclusion ReLEx SMILE shows remarkable stability over the entire range of myopias after 3 years, however primary undercorrection occurs predominantly in eyes of - 6.0 D, which necessitates nomogram adjustment.

Abstract
The ability of the spinal cord to recover after partial or complete transection, and even reinitiate motor function, was investigated in several studies in cats. It has been shown that even after a complete spinalisation at the level of T12/T13, the possibility of restoration of hind-limb function is good. Central pattern generators (CPGs), located in the spinal cord, play an important role in this situation. Although CPGs alone are unable to restore function, the combination of CPGs with targeted and consistent mobility training and, in some cases, hind-limb sensory stimulation is essential to improve function. These result in a reorganisation of the CPGs and neuronal networks in the spinal cord. The age of the animal at the time of injury and the extent and localisation of lesions, play a crucial role in recovery. A new focus of research is the influence of neurotransmitters/neuromodulators on spinal-cord regeneration. How and to what extent these factors support locomotor training remains for further clinical investigation.

Abstract
BACKGROUND Overview of the retropupillary implantation of iris claw intraocular lenses (Artisan®,Ophtec, Groningen, Niederlande and Verisyse(TM),AMO, Santa Ana CA). MATERIAL AND METHODS A literature search and review of implantation techniques, patient selection, potential complications and management strategies. RESULTS This approach has the advantage of a simple implantation technique, an anatomically correct implantation site (as compared to endocapsular implantation) and a relatively low complication rate. An intact iris is, however, a prerequisite for this technique. Ischemic vitreoretinopathies, such as diabetes or vascular occlusive entities, as well as uveitis might be considered as contraindications. CONCLUSIONS The retropupillary implantation of iris claw intraocular lenses is an interesting and especially time-effective rehabilitation technique for aphakia.

Abstract
BACKGROUND The four fundamental techniques of secondary intraocular lens (IOL) fixation, namely sulcus placement, scleral or iris suture fixation and scleral haptic fixation can be combined in special situations. AIM When is a combination of different techniques advisable? METHODS This article describes our experiences and gives an example of combined technique use. RESULTS These situations arise in cases when neighboring ocular structures are only partially preserved or show particular distinctive defects that can be repaired at the time of secondary IOL anchoring. This article presents a case of IOL-induced iris chafing and traumatic iridodialysis which was closed by a combined technique of iris suture and scleral suture fixation. CONCLUSION A combination of different anchoring techniques for secondary IOL implantation can achieve a simultaneous repair of perilenticular structures and reduce the amount of suture material used.

Abstract
Implantation of an intraocular lens (IOL) into the ciliary sulcus is the second most common implantation site after the regular capsular bag (in the bag) placement of an IOL. Although mainly not primarily intended, it is very often used in both complicated cataract surgery and secondary implantation due to IOL dislocation or aphakia. In most cases stable positioning is possible, especially when using optic capture techniques. A variety of difficulties can occur with sulcus implantation depending on the anatomical and surgical conditions present at the time of implantation. The most anterior position of the sulcus lense has to be considered for calculation of the refractive power of the IOL.

Abstract
There are many challenges in accomplishing tip-enhanced Raman spectroscopy (TERS) and obtaining a proper tip is probably the greatest one. Since tip size, composition, and geometry are the ultimate parameters that determine enhancement of intensity and lateral resolution, the tip becomes the most critical component in a TERS experiment. However, since the discovery of TERS the cantilevers used in atomic force microscopy (AFM) have remained basically the same: commercial silicon (or silicon nitride) tips covered by a metallic coating. The main issues of using metal-coated silicon cantilevers, such as wearing off of the metal layer or increased tip radius, can be completely overcome by using all-metal cantilevers. Until now in TERS experiments such probes have only been used in a scanning tunneling microscope or in a tuning fork-based shear force microscope but not in AFM. In this work for the first time, we show the use of compact silver cantilevers that are fully compatible with contact and tapping modes in AFM demonstrating their superb performance in TERS experiments.

Abstract
UNLABELLED AIM AND SETTING: To test the effects of crude extracts from flax (Linum usitatissimum) on progesterone and estradiol and ERα and β/PR production in choriocarcinoma cell lines Jeg 3 and BeWo. Tumor trophoblast cells (Jeg 3 and BeWo) were incubated in the presence of different concentrations of the flax crude extracts. Estradiol and progesterone production was measured. Estrogen receptor α and β as well as progesterone receptor expressions were also assessed. RESULTS In Jeg 3 cells, progesterone production was downregulated by flax root and leaves extract, while in BeWo cells only flax root extract did manage to downregulate progesterone production. ERβ expression was significantly downregulated by flax root and flax leaves extract in both cell lines; on the contrary, ERα expression was increased by flax leaves extract in BeWo cells. PR expression was downregulated by flax leaves extract in Jeg 3 and by flax root extract in BeWo cells. CONCLUSION Flax extracts derived from leaves and especially from roots can modify progesterone and possibly estradiol production, while at the same time they seem to alter ERβ expression. Further studies on animal models and adequately designed retrospective epidemiological studies are imperative to clarify this role upon progesterone.

Abstract
Consecutive synthesis methodologies for the preparation of the gold(I) carboxylates [(Ph(3)P)AuO(2)CCH(2)(OCH(2)CH(2))(n)OCH(3)] (n = 0-6) (6a-g) are reported, whereby selective mono-alkylation of diols HO(CH(2)CH(2)O)(n)H (n = 0-6), Williamson ether synthesis and metal carboxylate (Ag, Au) formation are the key steps. Single crystal X-ray diffraction studies of 6a (n = 0) and 6b (n = 1) were carried out showing that the P-Au-O unit is essentially linear. These compounds were applied in the formation of gold nanoparticles (NP) by a thermally induced decomposition process and hence the addition of any further stabilizing and reducing reagents, respectively, is not required. The ethylene glycol functionalities, providing multiple donating capabilities, are able to stabilise the encapsulated gold colloids. The dependency of concentration, generation time and ethylene glycol chain lengths on the NP size and size distribution is discussed. Characterisation of the gold colloids was performed by TEM, UV/Vis spectroscopy and electron diffraction studies revealing that Au NP are formed with a size of 3.3 (±0.6) to 6.5 (±0.9) nm in p-xylene with a sharp size distribution. Additionally, a decomposition mechanism determined by TG-MS coupling experiments of the gold(i) precursors is reported showing that 1(st) decarboxylation occurs followed by the cleavage of the Au-PPh(3) bond and finally release of ethylene glycol fragments to give Au-NP and the appropriate organics.
