Context.Given the high incidence of binaries among mature field massive stars, it is clear that multiplicity is an inevitable outcome of high-mass star formation. Understanding how massive multiples form requires the study of the birth environments of massive stars, covering the innermost to outermost regions.Aims.We aim to detect and characterise low-mass companions around massive young stellar objects (MYSOs) during and shortly after their formation phase. By the same means, we also probed the 3.8-μm emission that surrounds these massive protostars, in order to link the multiplicity to their star-forming environment.Methods.To investigate large spatial scales, we carried out anL′-band high-contrast direct imaging survey seeking low-mass companions (down toLbol ≈ 10 L⊙or late A-type) around thirteen previously identified MYSOs using the VLT/NACO instrument. From those images, we looked for the presence of companions on a wide orbit, covering scales from 300 to 56 000 au. Detection limits were determined for all targets and we tested the gravitational binding to the central object based on chance projection probabilities.Results.We have discovered a total of thirty-nine potential companions around eight MYSOs, the large majority of which have never been reported to date. We derived a multiplicity frequency (MF) of 62 ± 13% and a companion fraction (CF) of 3.0 ± 0.5. The derived stellar multiplicity and companion occurrence are compared to other studies for similar separation ranges. The comparisons are effective for a fixed evolutionary stage spanning a wide range of masses and vice versa. We find an increased MF and CF compared to the previous studies targeting MYSOs, and our results match the multiplicity rates derived among more evolved populations of massive stars. For similar separation ranges, we however confirm a higher multiplicity than that of T Tauri stars (∼30%), showing that the statement in which multiplicity scales with primary mass also extends to younger evolutionary stages. The separations at which the companions are found and their location with relation to the primary star allow us to discuss the implications for the massive star formation theories.Conclusions.Our findings do not straightforwardly lift the uncertainty as to the formation process of massive stars as a whole but we rather examine the likely pathways for individual objects. However, the wide distance at which companions are detected rather supports core fragmentation or capture as the main mechanisms to produce wide multiples. We find hints of triggered star formation for one object and discuss the massive star against stellar cluster formation for other crowded fields.
Initiierung und endokrine Kontrolle der Geburt bei Haussäugetieren – Teil 2
Authors: Schuler Gerhard 
Published: October 2023

ZusammenfassungDer endokrinen Kontrolle der Geburt liegt ein intensiver Signalaustausch zwischen Fetus, Plazenta und Mutter zugrunde. Abgesehen vom Schaf ist unser Wissen über die dabei zugrunde liegenden Prozesse immer noch sehr lückenhaft. Bisherige Beobachtungen lassen jedoch erhebliche Speziesunterschiede erkennen. Von entscheidender Bedeutung für den Eintritt der finalen, zur Austreibungsphase führenden Schritte der Signalkaskade ist der „präpartale Progesteronentzug“, der in Anhängigkeit von der relevanten Gestagenquelle in der Spätgravidität auf einer Luteolyse (z. B. Rind, Ziege, Büffel, Kameliden, Schwein) oder einem Zusammenbruch der plazentaren Gestagenproduktion (Schaf, Pferd) beruht. Das Wissen über die geburtsassoziierten Regelvorgänge ermöglicht es, für eine medikamentöse Geburtseinleitung speziesspezifische Regelmechanismen zu imitieren. Darüber hinaus stehen speziesunabhängige Wirkprinzipien wie die Blockade von Progesteronrezeptoren zur Verfügung. Neben der Wirksamkeit müssen unter Praxisbedingungen bei der Auswahl von Wirkstoffen weitere Aspekte wie die Verträglichkeit für Muttertier und Nachkommen sowie arzneimittelrechtliche Vorschriften berücksichtigt werden.

Published: October 2023

AbstractThe mammalian target of rapamycin (mTOR) inhibitors are used to prevent organ transplant rejection and are preferred over other immunosuppressants due to its low nephrotoxicity. However, mTOR inhibitors have been associated with various adverse effects including lymphedema. Although rare in incidence, previously known treatments for mTOR inhibitor-induced lymphedema were limited to discontinuation of related drugs and complex disruptive therapy with variable results.In this article, three patients who developed lymphedema in their lower limbs after using mTOR inhibitors, including two bilateral and one unilateral case, were treated with physiologic surgery methods such as lymphovenous anastomosis (LVA) and lymph node transfer. The efficacy of the treatment was evaluated.In the three cases described, cessation of the drug did not lead to any reduction in edema. The use of LVA and lymph node transfer resulted in early reductions in volume but failed to sustain over time. All patients underwent secondary nonphysiologic surgery such as liposuction resulting in sustained improvement.This series presents the first physiologic approach to mTOR inhibitor-induced lymphedema. Although further study is warranted, the physiologic surgical options may have limited success and nonphysiologic options may offer better sustainable results.

Resumo
Objetivo Analisar comparativamente as abordagens cirúrgicas por via posterior isolada e dupla abordagem para tratamento da escoliose severa.
Métodos Analisou-se retrospectivamente prontuários de 32 pacientes com escoliose de valor angular > 70° submetidos a tratamento cirúrgico em hospital terciário entre 2009 e 2019. Dividiu-se estes pacientes em dois grupos: Grupo VP com 17 pacientes submetidos a artrodese por via posterior isolada (VP) e Grupo VAP com 15 pacientes abordados por via anterior e posterior (VAP). O Grupo VP apresentou 16 pacientes do sexo feminino e 1 do masculino, com idade média de 16,86 anos. No grupo VAP, 10 pacientes do sexo feminino e 5 do masculino, com idade média de 17,71 anos. Os ângulos de Cobb foram mensurados por único cirurgião de coluna, manualmente, em radiografias panorâmicas, em ortostase no pré- e pós-operatório. Foram avaliados também peso, altura pré- e pós-operatória e duração do procedimento.
Resultados No Grupo VP, o ângulo de Cobb pré-operatório e pós-operatório, verificados na curva principal, foram respectivamente 96,06° ± 8,45° e 52,27 ± 15,18°, apresentando taxa média de correção de 0,54 ± 0,16. No grupo VAP, esses valores foram de 83,12° ± 11,60° para o ângulo de Cobb pré-operatório, 48,53 ± 10,76, pós-operatório, com a taxa de correção da curva principal de 0,58 ± 0,11.
Conclusão As duas formas de abordagem cirúrgica para tratamento de escoliose severa se equiparam quanto à taxa de correção da deformidade. Portanto, o acesso posterior isolado apresenta vantagem em relação a dupla via, baseado no menor tempo cirúrgico, menor tempo de internação e menos risco de complicações

Abstract
Background On September 10, 2022, a cholera outbreak was declared in Syria for the first time in over a decade of protracted conflict. As of May 20, 2023, 132,782 suspected cases had been reported, primarily in northwest and northeast Syria. We aim to provide a detailed description of water sources and clinical status of a patient cohort seen at a cholera treatment center (CTC) in northwest Syria.
Methods We retrospectively identified patients with confirmed cholera who presented to the CTC in Idlib governorate between October 8 and December 18, 2022. Data were obtained from clinical case records and analyzed in R v4.0.4.
Results Ninety-four patients (55.3% men) were treated at the CTC. Thirty-five patients were severely dehydrated (Plan C treatment), 54 had some dehydration (Plan B), and 5 had no dehydration (Plan A). Most patients were between 11 and 20 years old (n = 25, 26.6%) or 31 and 40 years old (n = 19, 20.2%). Note that 70.2% (n = 66) of patients were seen in November 2022 and most were from Harim district (n = 44, 46.8%). Public wells (n = 46, 48.9%) and water trucking (n = 41, 43.6%) were the most commonly used water sources. Note that 76.6% (n = 72) did not have access to chlorine-treated water. Forty-seven patients (50%) had more than five water, sanitation, and hygiene (WASH)-related cholera risk factors. Following treatment, six patients were transferred to another treatment center, three died (case fatality rate: 3.2%), and the remainder were discharged.
Conclusion Most patients reported WASH-related risk factors for cholera, reflecting the poor state of WASH in northwest Syria after over a decade of conflict. This relates to the direct and indirect impacts of urban and periurban violence as well as the underfunded humanitarian response. Strengthening WASH and health promotion are important components to control the outbreak.

ResumoObjetivo Avaliar a incidência de lesões cyclops sintomáticas que precisam de tratamento cirúrgico após a reconstrução do ligamento cruzado anterior (LCA) e estabelecer os possíveis fatores de risco intraoperatórios relacionados a elas.Métodos Trezentos e oitenta e nove pacientes com idades entre 18 e 50 anos submetidos à reconstrução primária do LCA foram avaliados de forma retrospectiva. Os pacientes foram divididos em grupos de acordo com a presença ou ausência de lesões cyclops sintomáticas e suas características foram comparadas. Não foram incluídos pacientes com lesões associadas que necessitassem de outros procedimentos cirúrgicos (à exceção de procedimentos extra-articulares ântero-laterais). A taxa de lesões cyclops sintomáticas foi registrada e os seguintes parâmetros foram avaliados: idade, sexo, tempo da lesão à cirurgia, tipo e diâmetro do enxerto, técnica de perfuração do túnel femoral, tipo de fixação, presença de hiperextensão do joelho, preservação do LCA remanescente, associação a procedimento extra-articular ântero-lateral, lesão de menisco associada e participação em esportes.Resultados Dos 389 pacientes avaliados, 26 (6,7%) desenvolveram lesão cyclops. Os pacientes com e sem lesão cyclops não diferiram quanto à idade, tempo da lesão à cirurgia, tipo ou diâmetro do enxerto, técnica cirúrgica, método de fixação femoral, presença de hiperextensão do joelho, preservação do LCA remanescente e lesão de menisco associada. O grupo com lesão cyclops apresentou mais mulheres (10 [38,4%] vs. 68 [18,7%]; razão de probabilidades [OR] = 2,7; p = 0,015), maior proporção de reconstrução extra-articular (18 [11,8%] vs. 8 [3,4 %]; OR = 3,8; p = 0,001) e maior proporção de prática esportiva (23 [8,6%] vs. 3 [2,5%]; OR = 3,6; p = 0,026).Conclusão Em nossa série, 6,7% dos pacientes necessitaram de remoção artroscópica das lesões cyclops. O sexo feminino, a reconstrução extra-articular associada e a prática esportiva foram fatores relacionados a essa lesão. A preservação do menisco remanescente não foi associada à formação de lesões cyclops.

Published: October 2023

AbstractThough posttraumatic cerebrospinal fluid (CSF) rhinorrhea and otorrhea are fairly common, blepharocele and blepharoencephalocele are rare, with only 15 cases reported to date.A 29-year-old female patient presented with a complaint of swelling of the right eyelid that had begun three months before. The patient had sustained a head injury 24 years prior to presentation.Imaging studies revealed the presence of a craniopalpebral CSF fistula. The patient underwent successful surgical repair of the fistula with craniotomy and duroplasty by autologous fascia lata graft.Delayed development of blepharocele 24 years after trauma is unusual, and, to our knowledge, the case herein reported is the first one in the literature.
Evaluation and obstacle analysis of high-quality development in Yellow River Basin and Yangtze River Economic Belt, China

Published: October 2023

AbstractBased on China’s new development philosophy, and following the idea of “assessing the overall levels firstly, then anchoring the subsystems contributions and finally identifying the obstacle factors”, an evaluation system of high-quality development (HQD) levels is constructed from five subsystems of innovative development (ID), coordinated development (CD), green development (GD), open development (OD) and shared development (SD). In this paper, the entropy weight TOPSIS model is used to measure the HQD levels of 19 provincial units located in the Yellow River Basin (YRB) and the Yangtze River Economic Belt (YREB) in 2010–2019, and with the assistance of the Obstacle Degree Model, the obstacle factors affecting the HQD of both are depicted. The results show that: (1) between 2010 and 2019, the HQD indices in YRB and YREB have been on an increasing trend, and the subsystems indices all show a trend of “GD > CD > SD > ID > OD”, but the overall levels of HQD in both is not high, and there is still much room for improvement. (2) YREB has a significantly higher HQD level than YRB. From 2010 to 2019, the average values of the HQD indices in YRB and YREB were 0.2886 and 0.4073, respectively, but the index in YRB improves at a faster pace than YREB, and the gap of HQD levels between the two show a trend of continuous reduction towards regional balance and coordination. (3) The analysis of obstacle factors shows that while OD and ID are the main obstacles to HQD in both basins, the impact of both on the resistance to HQD in both basins is on a decreasing trend. GD is another bottleneck for the HQD of YRB, and the pressure on GD in the middle and upper reaches of the provincial units in the basin is increasing, and the obstacles are on a rising trend.

Published: October 2023

AbstractThe primary objective of this research is to examine the diverse product attributes related to the credibility of organic food. Given that organic quality of food products is considered a credence attribute, establishing credibility plays a pivotal role in consumers’ decision-making processes when purchasing organic products. The lack of credibility represents a significant barrier to the growth of the organic market. Therefore, it is crucial to explore the specific product attributes that can enhance the perceived credibility of organic products. To assess the various factors influencing credibility, a choice-based conjoint method was employed. The study involved Hungarian participants (n = 652) and Polish participants (n = 290), who were asked to select a hypothetical product they deemed more credible. The findings reveal that the country of origin, appearance, and packaging exert the most substantial influence on the perceived credibility of organic food. Additionally, price and the place of purchase were identified as factors that also impact consumer perceptions.

Published: October 2023

Abstract
Erbium activated fluorophosphate glasses were synthesized with conceived characteristic combination, 59.5NH4H2PO4+15ZnO+15BaF2+10X+0.5Er2O3(X = LiF, NaF, CaF2, SrF2, AlF3) by melt quenching route. Based on the mass densities, and refractive indices, other physical properties i.e., dielectric constant (ε), reflection losses, molar refraction, internuclear distance and molar volume are determined. XRD has confirmed the non-crystalline character of the prepared glass samples. FTIR, FT-Raman have been employed to study the structural characteristics. Various radiative properties have been inferred through optical absorption measurements by standard Judd–Ofelt procedure. By excitation at 379 nm, all the glass hosts doped with constant concentration 0.5 mole% of Er3+have yielded intense green emission peak due to the transition 4S3/2 → 4I15/2 at 545 nm. Characteristic emission transition 4I13/2 → 4I15/2 at wavelength 1.53 μm has been studied extensively. Particularly the parameters related to that transition namely, stimulated emission cross-sections (σ
e) and optical gains (G) are calculated from emission spectra. Among all the fluorophosphate glasses, the one which has shown higher σ
e, and G values is sodium fluorophosphate (NFPE) glass. It is recommended for optical fiber amplification and NIR laser usage.

Abstract
We demonstrate Q-switched pulse generation at the 1562.5 nm region by using a 70 cm long erbium–bismuth co-doped alumina–germania–hafnium–yttria silica glass-based fiber as a gain medium in a simple ring resonator configured without saturable absorber and optical isolator devices. The Q-switching was obtained based on a stimulated Brillouin scattering assisted four-wave mixing effect in the gain medium, which induced the intensity modulation mechanism. The laser produced a multi-wavelength output comb centered at 1562.6 nm with a peak-to-peak spacing of about 0.09 nm due to nonlinear effects. Stable Q-switched operation of a hafnia–bismuth–erbium co-doped fiber laser was obtained at a pump power range of 129–319 mW with the repetition rate varying from 45.9 kHz to 89.3 kHz and the pulse width ranging from 8.8 µs to 3.58 µs. A maximum pulse energy of 26.9 nJ at an average output power of 2.4 dBm was achieved. This demonstrates a new passive technique based on a highly nonlinear gain medium for realizing Q-switched all-fiber laser sources.
Shaping ellipsoidal laser pulses in the scheme with black analog masks for photoinjector applications

Published: October 2023

Abstract
Today the electron beam emittance minimization race seems to slack due to insufficiency of beam shaping techniques. To fill the gap we propose a method for shaping a sharp 3D ellipsoidal boundary of laser pulses used in a photoinjector. To avoid distortions in the profiled laser beam, only black analog masks are exploited as shaping elements. A highly promising experimental distribution with a 3D boundary thickness better than 10% was obtained at the fundamental harmonic. The proposed scheme can be easily modified for multiplied harmonics of radiation.
Implications of the Stellar Mass Density of High-z Massive Galaxies from JWST on Warm Dark Matter
Authors: Lin Hengjie , Gong Yan , Yue Bin , Chen Xuelei 
Published: October 2023

Abstract
A significant excess of the stellar mass density at high redshift has been discovered from the early data release of James Webb Space Telescope (JWST), and it may require a high star formation efficiency. However, this will lead to large number density of ionizing photons in the epoch of reionization (EoR), so that the reionization history will be changed, which can arise tension with the current EoR observations. Warm dark matter (WDM), via the free streaming effect, can suppress the formation of small-scale structure as well as low-mass galaxies. This provides an effective way to decrease the ionizing photons when considering a large star formation efficiency in high-z massive galaxies without altering the cosmic reionization history. On the other hand, the constraints on the properties of WDM can be derived from the JWST observations. In this work, we study WDM as a possible solution to reconcile the JWST stellar mass density of high-z massive galaxies and reionization history. We find that, the JWST high-z comoving cumulative stellar mass density alone has no significant preference for either CDM or WDM model. But using the observational data of other stellar mass density measurements and reionization history, we obtain that the WDM particle mass with

Abstract
The NUMEN project aims to measure specific reaction cross sections to provide experimentally driven information about nuclear matrix elements of interest in the context of neutrinoless double beta decay (0νββ). In particular, it was proposed to use heavy – ion induced double charge exchange reactions as tools towards the determination of information on the nuclear matrix elements of 0νββ, strongly motivated by a number of similarities between the two processes. To this extent, the 20Ne + 130Te system was experimentally investigated in a multi-channel approach by measuring the complete net of reactions channels, namely double charge exchange, single charge exchange, elastic and inelastic scattering, one – and two – nucleon transfer reactions, characterized by the same initial projectile and target nuclei. The goal of the study is to fully characterize the properties of the nuclear wavefunctions entering in the 0νββ decay nuclear matrix elements. The experimental setup, the data reduction and some of the obtained results for the 20Ne + 130Te system will be presented and discussed.
