Published: July 2023

AbstractElectroanalytical and optical techniques are widely used in the development of nanomaterials-based sensor platforms. These techniques have a quick response, high sensitivity, and selectivity. Electroanalytical and optical techniques are widely used in the development of nanomaterial-based sensor platforms. These sensors must be able to detect biomarkers, pathogens, toxins, and pharmaceuticals in biological matrices associated with cardiovascular disease, cancer, and neurodegenerative diseases. Considering these pathophysiologies, numerous investigations have been undertaken to develop sensors for early diagnosis and treatment, utilizing nanomaterials such as quantum dots. Graphene quantum dots (GQDs), which are ideally nanometer-sized graphene fragments, have recently received increased attention due to their excellent physicochemical properties such as fast electron mobility, photostability, water solubility, biocompatibility, high specific surface area, and nontoxicity. Apart from the properties mentioned above, GQDs provideπ–πinteractions, electrostatic, and covalent interactions with an analyte, and ease of synthesis as well as the ability to combine with other nanomaterials, which have enabled their use in various sensing platforms. This review summarizes recent advances in GQDs-based nanocomposites for sensor applications, with a focus on electroanalytical and optical techniques, as well as current challenges and future prospects.

AbstractBackgroundThe precise mechanisms of hormone action responsible for the full course of events modulating folliculogenesis in crocodilian have not been determined, although histological features have been identified.ResultsTheAlligator sinensisovarian morphological characteristics observed at 1, 15, 30, 60, 90, and 300 days post hatching(dph) revealed that the dynamic changes in germ cells varied in different meiotic and developmental stages, confirming that the processes of folliculogenesis were protracted and asynchronous. The presence of endogenous follicle-stimulating hormone(FSH) mRNA and protein expression within the cerebrum at 1 dph, in parallel with the increase in germ cells within the germ cell nests(Nest) from 1 dph to 15 dph, suggested that endocrine regulation of the pituitary-gonad axis is an early event in oogonia division. Furthermore, the endogenous expression of FSH showed a trend of negative feedback augmentation accompanied by the exhaustion of maternal yolk E2observed at 15 dph. Such significant elevation of endogenous FSH levels was observed to be related to pivotal events in the transition from mitosis to meiosis, as reflected by the proportion of oogonia during premeiosis interphase, with endogenous FSH levels reaching a peak at the earliest time step of 1 dph. In addition, the simultaneous upregulation of premeiotic markerSTRA8mRNA expression and the increase in endogenous FSH further verified the above speculation. The strongly FSHr-positive label in the oocytes within Pre-previtellogenic follicles was synchronized with the significant elevation of ovarian cAMP detected at 300 dph, which suggested that diplotene arrest maintenance during early vitellogenesis might be FSH dependent. In addition, preferential selection in asynchronous meiotic initiation has been supposed to act on somatic supportive cells and not directly on germ cells via regulation of FSH that in turn affects downstream estrogen levels. This suggestion was verified by the reciprocal stimulating effect of FSH and E2on the accelerated meiotic markerSYCP3and by the inhibited cell apoptosis demonstrated in ovarian cell culture in vitro.ConclusionThe corresponding results contribute an expansion of the understanding of physiological processes and shed some light on the specific factors responsible for gonadotropin function in the early folliculogenesis of crocodilians.
Taste of asean: traditional food images from Southeast Asian countries
Authors: Putra Fajar Kusnadi Kusumah , Putra Mandradhitya Kusuma , Novianti Selvi 
Published: July 2023

AbstractGastronomy tourism and local food have become a powerful tool for tourism advertising because gastronomy often reflects the cultural identity of the destination. Local food images can help showcase the unique flavors of a particular region, making it more attractive to potential visitors. This study aims to analyze how regional tourism authorities share information about the diversity of traditional foods, promote gastronomic tourism, and enhance destinations' competitiveness by utilizing Instagram as a social media platform combining images with textual information. The ASEAN Tourism Online objectives are to promote the region as a single destination, increase tourism arrivals and receipts, and enhance regional connection. In this study, the official account of Southeast Asia Tourism on Instagram @visitsoutheastasiaofficial with keywords Taste of ASEAN marketing campaign. A qualitative approach using content analysis was used in this study. Data for this study were retrieved from 123 traditional food images posted on the official Instagram account from 2016 to 2022. A thematic analysis was used to classify themes. The findings presented categories ranging from the authenticity of traditional food, social media campaigns and promotions, local destination information, and gastronomic tourism activities. The majority of images posted related to the portrait of local cuisines. This analysis portrayed how the ASEAN tourism online wants to promote food as an attraction instead of food as a supporting element of tourism activities. The limitation of this study is only focused on the content of traditional visual food on the Instagram platform. Further research can be done using other social media platforms and comparing these findings with other destinations. It also provides an opportunity to gain insights into what people are saying about each destination, which can be helpful in terms of understanding customer preferences and opinions. The implication of this study will help national tourism organizations, culinary practitioners and academicians about the traditional food images on the social media platform to promote regional and city tourism. Additionally, it can help to identify potential opportunities for improvement or expansion within the region. Finally, researching other destinations through social media platforms can provide valuable information that could be used to create effective marketing strategies and campaigns.
Ultrasound findings to predict failure of conservative treatment in the appendix testis torsion
Authors: Salvo Neil Di , Parente Giovanni , Benivegna Dario , Di Mitri Marco , Thomas Eduje , Lima Mario 
Published: July 2023

Abstract
Background
Torsion of the appendix testis (TAT) is considered the most common cause of acute scrotum in childhood. When clinical and ultrasound (US) findings agree with the diagnosis, after testicular torsion has been excluded, conservative therapy is attempted whereas scrotal exploration and removal of the hydatid are required when medical therapy has failed. We hypothesized there are US features that can predict the failure of conservative therapy.

Methods
We conducted a retrospective analysis on pediatric patients treated for TAT. The age of patients, number of days spent with symptoms before the start of treatment, presence of epididymitis and/or hydrocele, and dimension of the twisted hydatid were analyzed. A search for a correlation between these variables and failure of conservative treatment was conducted.

Results
Patients were divided into 2 groups based on the efficacy of conservative management: responders (group I) and non-responders subjected to surgical treatment (group II). No statistically significant differences were registered in regard to age (p = 0.25), average dimension of hydatid (p = 0.09), and time gap between symptoms and the start of therapy (p = 0.92) between the 2 groups. An associated epididymitis was described in 27.5% of patients in group I and 41.7% in group II (p = 0.03; OR 1.89), and associated hydrocele was described in 33.4% of patients in group I and 45.8% in group II (p = 0.03; OR 1.83). Considering the odds ratios, the probability of surgical intervention when presenting only epididymitis without hydrocele is estimated to be 15%, when presenting only hydrocele without epididymitis: 9%, with both epididymitis and hydrocele: 74%, and without epididymitis nor hydrocele: 2%.

Conclusions
The presence of both epididymitis and hydrocele at first US evaluation is associated with a high probability of conservative treatment failure, thus predicting the need for surgical intervention.
Lymphangiography and lymphatic embolisation for the treatment of chyle leaks after neck surgery: assessment of lymphangiography findings and embolisation techniques
Authors: Kim Jinoo , Bang Dong Ho , Choi Tae Won , Won Je Hwan , Kwon Yohan 
Published: July 2023

Objective:
To assess lymphangiography findings and outcome of lymphatic embolisation to manage chyle leak after neck surgery.

Methods:
Consecutive cases of lymphangiography performed between April 2018 and May 2022 for management of chyle leaks related to neck surgery were retrospectively reviewed. Lymphangiography findings, techniques, and outcomes were analysed.

Results:
Eight patients (mean age: 46.5 years) were included. Six patients had undergone radical neck dissection for thyroid cancer, and two had undergone lymph node excision. Clinical presentations were: chyle drainage through Jackson Pratt catheters in five patients, lymphorrhea through surgical wounds in two, and enlarging lymphocele in one. Lymphangiography techniques included: inguinal lymphangiography in four patients, retrograde lymphangiography in three, and transcervical lymphangiography in one. Lymphangiography revealed leaks in the terminal thoracic duct in two patients, bronchomediastinal trunk in two, jugular trunk in three, and superficial neck channels in one. Embolisation techniques included: non-selective embolisation of terminal thoracic duct (n = 2), selective embolisation of the jugular trunk (n = 3), selective embolisation of the bronchomediastinal trunk (n = 2), and intranodal glue embolisation of superficial neck channels (n = 1). One patient underwent a repeat procedure. Chyle leak resolved in all patients over a mean of 4.6 days. No complication was encountered.

Conclusion:
Lymphatic embolisation seems to be effective and safe in managing chyle leaks after neck surgery. Lymphangiography allowed for the categorisation of chyle leaks according to their location. Post-embolisation patency of the thoracic duct may be preserved in chyle leaks that do not directly involve the thoracic duct.

Advances in knowledge:
Lymphatic embolisation is safe and effective in managing chyle leaks after neck surgery. On lymphangiography, the location of contrast media extravasation may not be consistent. The technique for embolisation should be based on the location of the leak. Post-embolisation patency of the thoracic duct may be preserved in chyle leaks that do not directly involve the thoracic duct.

Published: July 2023

Objectives: The purpose of this study was to evaluate the diagnostic value of quantitative magnetic resonance neurography (MRN) in chronic inflammatory demyelinating polyradiculoneuropathy (CIDP). We also compared various MRN parameters and determined the best performing one. Methods: Through literature searches in PubMed, Embase, Cochrane, Ovid MEDLINE and ClinicalTtrials.gov until March 1, 2023, we selected studies with the diagnostic performance of MRN in CIDP patients. The pooled estimated sensitivity and specificity of quantitative MRN parameters were determined by a bivariate random-effects model. Subgroup analysis was performed to evaluate the proper quantitative parameters and nerve sites. Results: A total of 14 quantitative MRN studies with 23 results gave a pooled sensitivity of 0.73 (95% CI 0.66–0.79) and a pooled specificity of 0.89 (95% CI 0.84–0.92). The area under the curve (AUC) was 0.89 (95%CI 0.86–0.92). Subgroup analysis of quantitative parameters showed the fractional anisotropy (FA) with the highest sensitivity of 0.85 (95% CI 0.77–0.90) and cross-sectional area (CSA) with the highest specificity of 0.95 (95% CI 0.85–0.99). The pooled correlation coefficient for interobserver agreements was 0.90 (95%CI 0.82–0.95). Conclusion: Quantitative MRN has considerable diagnostic value in CIDP patients with accuracy and reliability. FA and CSA can be promising parameters in the future diagnosis of CIDP patients. Advances in knowledge: This is the first meta-analysis of quantitative MRN in the diagnosis of CIDP.We have selected reliable parameters with cut-off value and provided new insights for subsequent diagnosis of CIDP.

Published: July 2023

Background: SARS-CoV-2 has extensively spread in cities and rural communities, and studies are needed to quantify exposure in the population. We report seroprevalence of SARS-CoV-2 in two well-characterized populations in Kenya at two time points. These data inform the design and delivery of public health mitigation measures. Methods: Leveraging on existing population based infectious disease surveillance (PBIDS) in two demographically diverse settings, a rural site in western Kenya in Asembo, Siaya County, and an urban informal settlement in Kibera, Nairobi County, we set up a longitudinal cohort of randomly selected households with serial sampling of all consenting household members in March and June 2021. Both sites included 1,794 and 1,638 participants in March and June 2021, respectively. Individual seroprevalence of SARS-CoV-2 antibodies was expressed as a percentage of the seropositive among the individuals tested, accounting for household clustering and weighted by the PBIDS age and sex distribution. Results: Overall weighted individual seroprevalence increased from 56.2% (95%CI: 52.1, 60.2%) in March 2021 to 63.9% (95%CI: 59.5, 68.0%) in June 2021 in Kibera. For Asembo, the seroprevalence almost doubled from 26.0% (95%CI: 22.4, 30.0%) in March 2021 to 48.7% (95%CI: 44.3, 53.2%) in July 2021. Seroprevalence was highly heterogeneous by age and geography in these populations—higher seroprevalence was observed in the urban informal settlement (compared to the rural setting), and children aged <10 years had the lowest seroprevalence in both sites. Only 1.2% and 1.6% of the study participants reported receipt of at least one dose of the COVID-19 vaccine by the second round of serosurvey—none by the first round. Conclusions: In these two populations, SARS-CoV-2 seroprevalence increased rapidly in the first 16 months of the COVID-19 pandemic in Kenya. It is important to prioritize additional mitigation measures, such as vaccine distribution, in crowded and low socioeconomic settings.

Published: July 2023

One of the important functions of personnel management at present is the management of corporate culture. The culturological approach in management allows you to combine all forces (resources) to achieve the goals of the organization, solving its tasks. This approach allows us to take into account the uniqueness of a particular company, to focus on the integration of all personnel in achieving the goals of the organization, the formation of loyalty, competencies, solidarity. Among the functions of the trade union noted in the documents of the organization, the organizational function, the organization of cultural mass, sports events, traditional professional holidays are presented. The role of management in the development of corporate culture is undeniable, at the same time, bipartisanship at the local level, as well as tripartism at other levels of social partnership presupposes the participation of employees (their trade union representatives) in the development of labor and other relations, in the improvement of corporate culture in the organization. The formation of values and norms, certain stereotypes of behavior occurs within the framework of the concept of social partnership in the organization. The role of the trade union as an organization uniting employees, as a participant in social partnership is in demand. This role is noted in the conducted research through the participation of the trade union in supporting traditions in the organization, participating in negotiations, discussing a Collective agreement, supporting staff in difficult situations (providing material, informational and legal assistance to trade union members and all employees of the organization) and other areas. The trade union participates in the management of corporate culture, which includes not only the management of the internal environment of the organization, but also the management of the image of the organization, its business reputation.

Published: July 2023

Modern conditions for the functioning of organizations require constant updating of approaches to personnel management, including new approaches are being formed in relation to the management of personnel motivation. Despite the unification of job duties by professional affiliation, each employee is individual and his needs, principles, beliefs are individual, and this should be considered when working with personnel. When forming a system of motivation and incentives, one should consider the specifics of each working generation in the organization. Theories of generations substantiate the important characterizing qualities of generations, their features, and the influence of historical and socio-economic factors during the formation of each generation separately. The authors, when assessing the existing system of motivation of the personnel of a construction organization, took the theory of generations as a criterion basis. Improving the system of motivation and incentives in the context of the theory of generations makes it possible for the organization to contribute to the growth of the efficiency of the work of personnel, reduce turnover and reduce the costs associated with training and adaptation of personnel. The results of the work can be used as the basis for improving the systems of motivation of the personnel of construction organizations. It is possible to use the results of the study in the development of motivation systems for business entities, departments for personnel management of enterprises and organizations.

Authors: Romanova I. 
Published: July 2023

The article discusses various aspects of friendship among employees of the organization. The positive impact of friendship on colleagues is described, as well as the risks of close working relationships. Possible tools for managing friendship on the part of management are also considered. The results of a survey of employees of Russian companies on the topic of friendly relations between colleagues are presented. It was found that the majority of respondents have friends at work and, in general, have a positive attitude towards friendship among colleagues. The survey participants see the greatest benefit from friendship in improving the moral and psychological climate of the team, and the biggest adverse effect of friendship is, in their opinion, “distraction from work.”
