Abstract
Introduction: In lateral ankle instability, anatomical ligament reconstructions are generally performed using arthroscopy. The ligament graft is passed through the talar, fibular and calcaneal tunnels, reconstructing the anterior talofibular and calcaneofibular (CFL) bundles. However, the calcaneal insertion of the CFL needs to be performed in an extra-articular fashion, and cannot be carried out under arthroscopy, thus requiring specific anatomical landmarks. For obtaining these landmarks, methods based on radiography or surface anatomy have already been described but can only offer an approximate identification of the actual CFL anatomical insertion point. In contrast, an ultrasound technique allows direct visualization of the insertion point and of the sural nerve that may be injured during surgery. Our study aimed to assess the reliability and accuracy of ultrasound visualization when performing calcaneal insertion of the CFL with specific monitoring of the sural nerve.
Material and methods: Our anatomical study was carried out on 15 ankles available from a body donation program. Ultrasound identification of the sural nerve was obtained first with injection of dye. A needle was positioned at the level of the calcaneal insertion of the CFL.
After dissection, in all the ankles, the dye was in contact with the sural nerve and the needle was located in the calcaneal insertion area of the CFL. The mean distance between the sural nerve and the needle was 4.8mm (range 3–7 mm).
Discussion-Conclusion: A pre- or intra-operative ultrasound technique is a simple and reliable means for obtaining anatomical landmarks when drilling the calcaneal tunnel for ligament reconstruction of the lateral plane of the ankle. This tunnel should preferably be drilled obliquely from the heel towards the subtalar joint (1h-3h direction on an ultrasound cross-section), which preserves a maximum distance from the sural nerve for safety purposes, while allowing an accurate anatomical positioning of the osseous tunnel.
Analysis and design of a novel RF MEMS switch with low pull-down voltage, high return loss, and high isolation at 10- 60GHz

Abstract
This paper presents a novel radio frequency micro-electro-mechanical systems (RF MEMS) switch fabricated on a high resistivity silicon substrate. Slots, like square interleaved slots and split-ring slots, are used in the transmission-line to get better RF performance. Comparing three switch structures with different slot cells, the switch with square interleaved slots is suitable at Ka-band (26 ~ 40GHz), but the switch with split-ring slots can be applied to RF circuits at 10-60GHz. The switch with split-ring slots is optimal for the switching mechanism in diverse 5G RF circuitry. When it works at 30GHz, it shows a low insertion loss better than − 0.256dB, a low re-turn loss better than − 22dB, and the isolation is observed below − 39dB. Its “pull-down” voltage is 6.5V. Due to its outstanding performance, the proposed RF MEMS switch is suitable for various applications.
Regularizing fuel-optimal, multi-impulse trajectories
Authors: Oshima Kenta 
Published: April 2023

Abstract
The regularization theory has successfully enabled the removal of gravitational singularities associated with celestial bodies. This paper merges regularizing techniques into a multi-impulse trajectory design framework that requires delicate computations specifically in a fuel minimization problem. Regularized variables based on the Levi-Civita or Kustaanheimo-Stiefel transformation express instantaneous velocity changes in a gradient-based direct optimization method. The formulation removes the notorious singularities associated with null thrust impulses from derivatives of an objective function in the fuel minimization problem. The favorite singularity-free property enables accurate reductions of unnecessary impulses and additions of necessary impulses for local optimal solutions in an automatic manner. Examples of fuel-optimal, multi-impulse trajectories are presented including novel transfer solutions between a near rectilinear halo orbit and a distant retrograde orbit.
Representation of Modes of Atmospheric Circulation Variability by Self-organizing Maps: A Study Using Synthetic Data
Authors: Stryhal Jan , Beranová Romana , Huth Radan 
Published: April 2023

Abstract
Self-organizing maps (SOMs) represent a popular tool for classifying atmospheric circulation patterns. One of their traditional applications has been to link typical synoptic-scale patterns to large-scale teleconnections, or modes of low-frequency circulation variability. However, recently there have been attempts to interpret an array of SOM nodes directly as a continuum of teleconnections, grounded in SOMs’ ability to combine two otherwise distinct approaches to data analysis, that is, exploratory projection (or, dimensionality reduction) and classification. This conceptual shift calls for methodological studies that would improve our understanding of how orthogonal modes of variability, typically used to describe teleconnections, relate to SOM outputs. Here, we define three idealized modes of variability and use their various combinations to generate synthetic data sets. Many variants of SOMs are generated for SOMs of various shapes and sizes. The results show that projection of modes on a SOM array is sensitive not only to data structure, but also to various SOM parameters. The leading mode of variability projects rather strongly on SOMs if its explained variance is markedly higher than that of the second-order mode; the remaining modes project considerably more weakly, and all modes tend to blend when their explained variance is similar, which leads to underrepresentation of some phases of modes and/or combinations of modes among the SOM patterns. Furthermore, we show that some features of SOM topology that were previously considered a proof of data nonlinearity appear even if the underlying modes of variability are strictly linear.
Elegy for an erōmenos: Paul Silentiarios, Queer Desire, and Funerary Epigram (AP 7.560)
Authors: Smith Steven D. 
Published: April 2023

This essay advances a queer interpretation of a single funerary epigram by the early Byzantine poet Paul Silentiarios (Anthologia Palatina 7.560). The poem commemorates the life of Leontios, a young man from a faraway homeland whose premature death while living abroad (presumably in Constantinople) meant that his parents could not bury him; instead, Leontios’ grave is surrounded by the men who loved him in his adopted city. The essay draws on the insights of queer theorists Leo Bersani, Lee Edelman, and José Esteban Muñoz while also applying a rigorous philological approach to uncover how the poet uses the poetic conventions of funerary epigram to express joy in a shared carnality that affirms the intimacy of homosocial relations.
A Contribution to the Study of the Development of Museum Activities during World War II in Occupied Serbia
Authors: Krivošejev Vladimir , Ristanović Rade 
Published: April 2023

Common stereotypical attitudes suggest that more extensive organized activities aimed at expanding the network of institutions for the protection of cultural assets began to be undertaken only after the end of World War II, under the auspices of the Communist party, when a new socialist social system was established. It was then, in 1947, that the Institute for the Protection of Cultural Monuments of Serbia was founded, followed by other local institutes of this kind. In that same period, local archives (archival centres) began to be established, increasing the capacity of archival activities initiated in 1898 with the founding of the State Archives of Serbia. At the same time, a series of new laws were passed; in addition, a number of museums were founded throughout Serbia, thus developing the museum network, which had previously – since the founding of the Serbian Museum (Muzeum serbski) in 1844 – expanded mainly in Belgrade, with only a small number of museums in other cities and towns in Serbia.
New research has shown that even during the German occupation in World War II, under the collaborationist government of general Milan Nedić new institutions were founded, partly actually and partly nominally, with the aim of establishing a functional protection network. With the introduction of appropriate legal acts (the Decree on the protection of cultural heritage), the first institution to be founded was the Institute for the Preservation of Cultural Heritage in May 1942. It was not only the precursor of today’s Institute for the Protection of Cultural Monuments of Serbia but also a central heritage institution, with connections to museums which began to be founded in county centres from the autumn of 1942 onwards. Committees were formed, administrators appointed and guidelines for further activities laid down. In the meantime, starting in April 1942, courses for museum workers were organized in Belgrade, and similar training was planned to take place in other cities in Serbia; also, a special Museum Act was being drafted.
It would seem that, although certain activities were recorded, museums founded during World War II did not have “firm foundations” and as of the latter half of 1943 there is no more mention of them, and the Museum Act was not passed. On the other hand, it is indicative that soon after the end of the war, musems were founded in all the towns and cities where initiatives for their founding had been recorded during the years of German occupation.
A contribution to the Transdisciplinary Terminology of Cultural Heritage
Authors: Nikolić Aleksandra 
Published: April 2023

In the last two decades, the changes in the concept of cultural heritage intensified the attempts to create the foundations and standardize the nomenclature of heritage studies and the heritage theory. The standardization attempts mainly come from the professional associations and international organizations dealing with heritage conservation, but, at the same time, they reflect novel theoretical stand points, being continuously built in the conservation practice. These changes in heritage theory allow for a wider interdisciplinary and transdisciplinary insights in the field. Such a situation opens a question of terminological compatibility of different fields expressing direct or indirect interest in cultural forms and processes, an example of which is covering a range of research programs under the umbrella term of cultural evolution. In this article, an instrumental definition of cultural heritage is generated to support the terminological analysis. The elements of this definitions are further used as a basis for a review of terminology in the fields of cultural evolution and cultural heritage, in order to create clusters of compatible terms in both fields. This article aims at stressing the need for transdisciplinary knowledge synthesis and integrated heritage terminology.

Introduction. Although acute cough in acute inflammatory diseases of the upper respiratory tract seems to be a minor problem and can be stopped on its own, it holds the leading position among all reasons for population receiving health care due to significant decrease in life quality.Purpose. To analyze the cough severity in patients with acute nasopharyngitis with intoxication syndrome in the treatment of systemic non-steroidal anti-inflammatory drugs (NSAIDs) and local interferon therapy.Materials and methods. The study included 62 patients with acute nasopharyngitis with intoxication syndrome, in the period from the onset of the first symptoms to the visit to the doctor was no more than 24 hours. They were divided into 2 groups: group 1 − 32 people (14 men, 18 women, age 34.4 ± 10.3 years) received traditional systemic therapy with NSAIDs, group 2 − 30 people (13 men, 17 women, age 41.1 ± 13.7 years) received interferon-α2b intranasally. Cough severity was assessed using a 3-point visual analog scale (VAS) on the day of admission and for the next 7 days.Results. On the 1st day dry cough was observed in 62.5–63.3% of cases. Starting from the 3rd day of observation, there were statistically significant differences in the intensity of this symptom between the groups. In the traditional therapy of NSAIDs, an increase in the number of patients with a complaint of cough, and an increase in its severity compared with the first day of observation was revealed. They lasted until the 6th day of illness, which was explained by the spread of the inflammatory process to the trachea and bronchi. In the treatment of local interferon therapy, cough regression was noted on day 4 in 83.3% of cases, with its complete disappearance in this group on day 6. The total duration of cough in group 1 was 6.0 (5.0; 8.0) days, in group 2 – 2.0 (1.0; 3.0) days.Conclusion. In acute inflammatory diseases of the upper respiratory tract, cough in the absence of prescribing drugs that affect this symptom persists on the eighth day of observation in 56.2% of patients with traditional therapy with systemic NSAIDs.

Published: April 2023

Abstract

Waterborne diseases remain a significant public health problem, and biosand filters (BSFs) are a common household water filtration method for improving drinking water quality to prevent diseases. The purpose of this study was to evaluate the effectiveness of BSFs over time in a rural Rwandan community. Sixteen BSFs were installed – eight in 2015 and eight in 2018. Influent and effluent samples were tested with Colilert Presence/Absence kits in 2015, 2017, 2018, 2019, and 2022. About 92.9% of filters were still in use in July 2022, but only 64.3% were functioning well, and 50% of effluent samples tested positive for fecal coliforms. A Kruskal–Wallis H test showed no statistically significant difference in effluent percent positive for fecal coliforms by filter age [χ2 (1) = 4.00, p = 0.41]. Recorded observations about each filter, such as rusted diffuser plates, may be useful for understanding the need for maintenance over time.

Published: April 2023

Abstract:
Nowadays, antimicrobial therapies have become a very challenging issue because
of a large diversity of reasons such as antimicrobial resistance, over consumption
and misuse of antimicrobial agents, etc. A modern, actual and very useful approach in antimicrobial
therapy is represented by the use of hybrid drugs, especially combined five
and six-membered ring azaheterocycles. In this review, we present an overview of the recent
advanced data from the last five years in the field of hybrid diazine compounds with
antimicrobial activity. In this respect, we highlight here essential data concerning the synthesis
and antimicrobial activity of the main classes of diazine hybrids: pyridazine, pyrimidine,
pyrazine, and their fused derivatives.
Bioactive Pentacyclic Triterpenes Trigger Multiple Signalling Pathways
for Selective Apoptosis Leading to Anticancer Efficacy: Recent Updates
and Future Perspectives
Authors: Banerjee Jhimli , Samanta Sovan , Ahmed Rubai , Dash Sandeep Kumar 
Published: April 2023

Abstract:
Nowadays, discovering an effective and safe anticancer medication is one of the major
challenges. Premature death due to the unidirectional toxicity of conventional therapy is common in
cancer patients with poor health status. Plants have been used as medicine since prehistoric times, and
extensive research on the anticancer properties of various bioactive phytomolecules is ongoing. Pentacyclic
triterpenoids are secondary metabolites of plants with well-known cytotoxic and chemopreventive
properties established in numerous cancer research studies. The lupane, oleanane, and
ursane groups of these triterpenoids have been well-studied in recent decades for their potential antitumor
activity. This review delves into the molecular machinery governing plant-derived triterpenes'
anticancer efficacy. The highlighted mechanisms are antiproliferative activity, induction of apoptosis
through regulation of BCL-2 and BH3 family proteins, modulation of the inflammatory pathway, interference
with cell invagination and inhibition of metastasis. Lack of solubility in mostly used biological
solvents is the major barrier to the therapeutic progress of these triterpenoids. This review also
highlights some probable ways to mitigate this issue with the help of nanotechnology and the modification
of their physical forms.

Published: April 2023

Introduction:Since mothers often express higher levels of stress, anxiety and depression, it is important to evaluate the effect of Covid-19 on their mental health during pregnancy and postpartum.Objective:The aim of this study was to explore the concerns of mothers in the postpartum period amidst the Covid-19 pandemicMethods:This was a descriptive cross-sectional study on 600 postpartum mothers. The sample size was determined based on the households covered by the health centers. The selected mothers completed a demographic questionnaire and Cambridge Worry Scale (CWS).Results:The mean age of study participants was 28.9(6.3)and 364 (60.7%) mothers had excessive anxiety during pregnancy. The highest concern was related to the fear of congestion in the maternity ward with a mean of 2.48, and the lowest level of concern was related to the health status of the mother with a mean of 1.41.Conclusion:we recommend that the health sector adopt new methods of providing care to mothers. Implementation of tests for assessment of the mother's mental state during pregnancy by a midwife consultant is also recommended
Immediate Reaction to Propranolol: An Extremely Rare but Important
Condition. A Case Report
Authors: González-Bravo Lucía , Sánchez-González María-José , Barbarroja-Escudero José , Monjo-Paz Josefa , Matas-Dominguez Dorotea , Alvarez-Mon Melchor 
Published: April 2023

Introduction:
Beta-blockers involve a group of drugs widely used nowadays. Propranolol
was the first beta-blocker available in the market. It is the most prescribed first-generation betablocker
and is commonly used. Beta-blocker allergy is extremely unusual. Only an isolated case of
an urticaria reaction to propranolol has been published in 1975.

Case Presentation:
We present a 44-year-old man. In 2016, he was treated with a daily dose of 5
mg of propranolol prescribed for a diagnosis of essential tremor. On the third day of medical
treatment, he experienced an episode of generalized urticaria directly related to the administration
of propranolol. He continued with his habitual treatment and he had no other urticaria episodes. A
drug provocation test was carried out with gradually increasing doses of the culprit drug. Thirty
minutes after a total cumulative dose of 5 mg, the patient had several hives on the chest, abdominal
region and arms. Two weeks later, a new drug provocation test was performed to bisoprolol as an
alternative beta-blocker, with good tolerance.

Conclusion:
We describe a new case of urticaria secondary to propranolol, presenting as an immediate
hypersensitivity reaction. Bisoprolol has been succesfully proved to be a safe option.
Bisoprolol is a second-generation beta-blocker, it is available and commercialized worldwide,
which makes it a good alternative.
Outbreak of Monkeypox Virus Disease: An Update on Epidemiology,
Pathophysiology and Available Treatment Options
Authors: Kumar Akash , Angaria Neeti , Singh Gurvinder , Kumar Rajesh 
Published: April 2023

Abstract:
The monkeypox virus is a zoonotic illness with a tropical distribution in Africa, and around
the world. The disease is spread through contact with infected animals or humans, and can also be
spread from person to person through close contact with respiratory or bodily fluids. Fever, swollen
lymph nodes, blisters, and crusted rashes characterize the disease. The incubation period is five to
twenty-one days. It is difficult to distinguish the rash caused by infection from varicella and smallpox.
Laboratory investigations are essential aspects of illness diagnosis and surveillance, and novel tests are
required for more accurate and faster diagnosis. Antiviral drugs are being used to treat monkeypox.
Scarring as well as other comorbidities, are prevalent in survivors, with the case mortality rate varying
from 1 to 11%. The virus was found in monkeys at a Danish research facility in 1958, from which the
term ‘monkeypox’ is derived. The primary human case was found in a child in the Democratic
Republic of the Congo (DRC) in 1970. The World Health Organisation (WHO) has recently declared
monkeypox a public health emergency of international concern. This manuscript attempts to review the
various aspects of monkeypox disease and its allopathic as well as alternative treatment options
available and serves as a valuable resource for healthcare professionals, researchers, and the general
public.
