Background

The gut microbiota of fish confers various effects on the host, including health, nutrition, metabolism, feeding behaviour, and immune response. Environment significantly impacts the community structure of fish gut microbiota. However, there is a lack of comprehensive research on the gut microbiota of bighead carp in culture systems. To demonstrate the impact of culture systems on the gut microbiome and metabolome in bighead carp and investigate a potential relationship between fish muscle quality and gut microbiota, we conducted a study using 16S ribosomal ribonucleic acid sequencing, gas chromatography-mass spectrometry, and liquid chromatography-mass spectrometry techniques on bighead carp in three culture systems.

Results

Our study revealed significant differences in gut microbial communities and metabolic profiles among the three culture systems. We also observed conspicuous changes in muscle structure. The reservoir had higher gut microbiota diversity indices than the pond and lake. We detected significant differences in phyla and genera, such as Fusobacteria, Firmicutes, and Cyanobacteria at the phylum level,Clostridiumsensu stricto1,Macellibacteroides,Blvii28 wastewater sludge groupat the genus level. Multivariate statistical models, including principal component analysis and orthogonal projections to latent structures-discriminant analysis, indicated significant differences in the metabolic profiles. Key metabolites were significantly enriched in metabolic pathways involved in "arginine biosynthesis" and "glycine, serine, and threonine metabolism". Variation partitioning analysis revealed that environmental factors, such as pH, ammonium nitrogen, and dissolved oxygen, were the primary drivers of differences in microbial communities.

Conclusions

Our findings demonstrate that the culture system significantly impacted the gut microbiota of bighead carp, resulting in differences in community structure, abundance, and potential metabolic functions, and altered the host's gut metabolism, especially in pathways related to amino acid metabolism. These differences were influenced substantially by environmental factors. Based on our study, we discussed the potential mechanisms by which gut microbes affect muscle quality. Overall, our study contributes to our understanding of the gut microbiota of bighead carp under different culture systems.
The Sikchi and the recorded cases of Seungjeongwon-Ilgi
Authors: Ko Byoung-Seob
Published: April 2023

Sikchi begins with mankind's efforts to maintain life while consuming natural food. The history of Korean food, a long experience of adapting to nature, can be found since prehistoric times. For example, Bangudae (a rock picture of hunting whales) showed how individuals gained knowledge on edible things in nature to survive. Also, Korea's specific vegetation, climate, and culture led to development of the Sikchi suitable for Koreans. The myth of Dangun of Gojoseon dynasty demonstrated the first historical record of the Sikchi. Although the Sikchi theory was established in China, Korean food therapy was systematized and developed into a unique diet that reflects our hyangyak (Korean herbal medicine) and constitution. For the king and royal family's health, Seungjeongwon-Ilgi (national-level documents of royal records) and other medical books recorded many examples of Sikchi practice, which were different from China or Japan. The wide spread of the royal Sikchi practice among citizens promoted the notion that food was a useful way to promote health and treat disease. The Sikchi should be seen as not only a kind of life-sustaining method but medicine and food-based medicinal food therapy. Further, the Sikchi refers to the treatment process of adjusting the gaps between medicine and the patient's condition with the mercenary technique called sumgoreugi (take a breather).

Background

Many studies and organizations described bases of pregnancy timing after bariatric surgeries, but there is still a need for uniform scientific evidence for accurate timing.

We aimed to assess pregnancy outcomes and neonatal findings by timing of surgery to pregnancy to compare adverse perinatal outcomes among women who underwent bariatric surgery prior to pregnancy with those who had not.

Patients and methods

We included 200 pregnant females who previously performed different bariatric surgeries. All pregnant females were divided into three groups: early group of patients who were conceived ≤ 12 months from bariatric surgery included 50 patients (25.0%), middle group of patients who were conceived from 12 to 24 months from bariatric surgery included 50 patients (25.0%) and late group of patients who were conceived > 24 months from bariatric surgery included 100 patients (50.0%).

Results

There is a more liability to preterm deliveries in the early group in comparison with the middle and late group (P = 0.064). Gestational weight gain in the early group was lower than the middle and the late group (P = 0.002). Females in the early group have a more liability to inadequate gestational weight gain in comparison with in the middle and late group P < 0.001).

Neonatal birth weight in the early group was significantly lower than the middle and late group P < 0.001).

Conclusion

We supported recommendations of postponing pregnancy for more than 12 months after performing bariatric surgery which allowed stabilization of maternal weight, allowing adequate gestational weight gain, better fetal and maternal health later on.
Paget’s disease of bone: the first case reported in Iraqi Kurdish
Authors: Hasan Trefa Salih , Faeq Abdulsatar Kamil
Published: April 2023

Background

Paget’s disease of bone (PDB) is a chronic bone disorder which insidiously evolves parallel with the aging process. The affected bone has a distinct imaging appearance, and the clinical manifestations are variable. This disease is ubiquitous among people of Anglo-Saxonian origin. However, it is rarely reported among Asian descents.

Case presentation

Here, the first diagnosed case of Paget’s disease of bone in an Iraqi Kurdish patient, a gentleman in his seventh decade of life underwent sectional imaging for evaluation of spine hopefully to find a potential musculoskeletal or neurological culprit behind his back discomfort. Biochemical confirmation tests were demanded based on the state of the art of the typical radiological judgment, perhaps negating pathological tissue affirmation. Marked geographical variation of the disease occurrence made it seldom to encounter such entity in the Middle East, particularly in Iraq. To the author’s knowledge, scarce cases have been described in Iraq, none in the Kurdish population.

Conclusion

This case report elicits an extremely rare metabolic osseous disease that was radiologically diagnosed at venture when bone window computed tomography (CT) is performed for an unrelated indication.

Introduction/Purpose

Head impacts associated with American football have been associated with short- and long-term disrupted cognitive performance. In this study, we aimed to determine the effects of an acute game of American football on cognitive function, memory, morphological changes, and functional connectivity in the brain.

Methods

Twelve members (mean ± standard deviation: age, 26.8 ± 5.2 yr; height, 183 ± 6.5 cm; weight, 98.8 ± 23.6 kg) of the Israel National American Football team were assessed 1 wk before (PRE) and 24-h post (24P) game. No head injuries to any of the players participating in the study occurred. All study participants were scanned using a Siemens Prisma 3-T magnetic resonance imaging (MRI) scanner to determine changes in resting-state functional MRI (fMRI) by measuring each participant’s connectivity of subcortical regions. In addition, brain-derived neurotrophic factor (BDNF) concentration and cognitive function were measured at each assessment.

Results

A significant increase in BDNF concentration (33%, P = 0.007) was noted at 24P. In addition, significant increases (p < 0.05) in cerebral connectivity within the hippocampus, amygdala, and the connections between the hippocampus and the somatomotor areas were noted between PRE and 24P. Elevations in hippocampus connectivity were correlated with changes in acute memory (r = 0.72, P = 0.03), and decreases in somatomotor–hippocampus connectivity were significantly correlated with a greater change in BDNF concentration (r = −0.67, P = 0.01). No significant changes were found in brain volume, cognitive function, or between brain connectivity and other regions.

Conclusions

The fMRI results suggested that, even during an American football game in which no known head injury occurred, changes in neurotrophin concentrations were correlated with morphological changes in the parietal and frontal regions of the brain.

Υπάρχει έλλειψη ερευνών που διερευνούν το πεδίο των Διαταραχών Λόγου και Γλώσσας (SLD) στο ελληνικό πεδίο της πρωτοβάθμιας εκπαίδευσης. Για το λόγο αυτό, η συγκεκριμένη μελέτη επεδίωκε να ερευνήσει τα εξής δύο σημεία: (i) να εντοπιστεί η φύση και η έκταση των δεξιοτήτων ομιλίας, γλώσσας και επικοινωνίας των Ελλήνων μαθητών με αισθητά αργή πρόοδο, και (ii) να εξεταστεί η διδασκαλία αυτών των μαθητών στο ελληνικό δημοτικό σχολείο και σε τμήματα ένταξης. Η μελέτη πραγματοποιήθηκε σε δύο φάσεις. Για την πρώτη φάση, οι μαθητές των οποίων η ανάπτυξη της ομιλίας και της γλώσσας ήταν κάτω από τις προσδοκίες, αξιολογήθηκαν χρησιμοποιώντας μια σειρά τεστ. Η δεύτερη φάση περιελάμβανε επτά μελέτες περιπτώσεων. Μαζί οι δύο φάσεις, παρείχαν ένα πλούσιο προφίλ της λειτουργίας του λόγου και της γλώσσας των μαθητών που είχαν διαγνωστεί με Διαταραχές Λόγου και Ομιλίας αλλά και με Μαθησιακές Δυσκολίες και εξέταζαν την εκπαίδευση που τους προσφέρθηκε στις τάξεις του δημοτικού σχολείου. Τα αποτελέσματα της έρευνας ανέδειξαν τον πολύπλοκο χαρακτήρα των Διαταραχών Λόγου και Ομιλίας, τις ομοιότητες στο προφίλ της γλώσσας και τις μη λεκτικές δεξιότητες συλλογισμού των Διαταραχών Λόγου και Ομιλίας και άλλων αντίστοιχων δυσκολιών. Αυτό εγείρει ερωτήματα σχετικά με το αν οι Διαταραχές Λόγου και Ομιλίας, όπως χρησιμοποιείται ο όρος σε αυτά τα σχολεία, είναι ένας ξεχωριστός τομέας δυσκολίας ή σε συνέχεια με άλλους τομείς δυσκολιών. Επιπλέον, η μελέτη έθεσε ερωτήματα σχετικά με την αξιολόγηση και τον προσδιορισμό των Διαταραχών Λόγου και Ομιλίας στο ελληνικό πλαίσιο, καθώς και την πρακτική διδασκαλία των μαθητών που αντιμετωπίζουν τέτοιες δυσκολίες.

Αντικείμενο μελέτης της διατριβής αποτελεί η οργάνωση της παραγωγής και της διακίνησης προϊόντων που παράγονταν υπό τον έλεγχο των μυκηναϊκών κέντρων. Ειδικότερα, η εργασία επικεντρώνεται σε ζητήματα ομοιογένειας και ποικιλομορφίας που εντοπίζονται στις διοικητικές πρακτικές για τέσσερις τομείς της παραγωγής, την υφαντουργική παραγωγή, την παραγωγή αρωματικού ελαίου, την κατασκευή αρμάτων και τη μεταλλουργία. Η ανάλυση των δεδομένων του κάθε τομέα της παραγωγής έγινε χρησιμοποιώντας ως μεθοδολογικό εργαλείο το chaîne opératoire. Για κάθε τομέα της παραγωγής παρατέθηκαν τα διαθέσιμα δεδομένα για τον γραφειοκρατικό έλεγχο, τους χώρους των παραγωγικών δραστηριοτήτων, το εμπλεκόμενο ανθρώπινο δυναμικό. Παρουσιάσθηκαν επίσης, πληροφορίες για τους γραφείς, τους χώρους της γραφειοκρατικής δραστηριότητας και τη λειτουργία τους. Στη συνέχεια της εργασίας επιχειρήσαμε να εντάξουμε τα αποτελέσματα των κεφαλαίων που προηγήθηκαν στο γεωγραφικό και χρονολογικό τους πλαίσιο. Εξετάσθηκαν ζητήματα ομοιογένειας και ποικιλομορφίας διαφόρων τομέων της παραγωγής στο ίδιο ανάκτορο αλλά και ζητήματα διαχείρισης της παραγωγής και της διακίνησής της μεταξύ των διαφoρετικών ανακτορικών κέντρων. Συνεκτιμώντας το σύνολο του υλικού, διατυπώσαμε ορισμένα βασικά συμπεράσματα για τον ρόλο και την έκταση που καταλαμβάνουν οι βιοτεχνικές δραστηριότητες στα ανακτορικά κέντρα. Η εικόνα που αναδεικνύεται είναι αρκετά σύνθετη και πολύπλοκη. Φαίνεται ότι τα ανακτορικά κέντρα δεν οργάνωναν με τον ίδιο τρόπο και δεν ήλεγχαν στον ίδιο βαθμό τους διαφορετικούς τομείς της παραγωγής. Η έρευνα μας οδήγησε στο γενικό συμπέρασμα ότι στοιχεία ομοιογένειας και ετερογένειας συνυπάρχουν σχεδόν σε όλες τις όψεις των ζητημάτων που εξετάσαμε κι εκείνο που φαίνεται να μεταβάλλεται είναι η αναλογία της παρουσίας τους. Τα κενά που προκύπτουν από την τυχαία ή μη απουσία δεδομένων και την ασυγχρονία των αρχείων από τα διάφορα ανακτορικά κέντρα, καθιστούν ακόμη πιο δύσκολη την προσπάθεια να διαχειριστούμε το πλήθος των ετερόκλητων στοιχείων. Σε ορισμένες περιπτώσεις ωστόσο προτείνουμε ότι οι ομοιότητες και οι διαφορές που παρατηρούνται μπορούν να αποδοθούν σε πολλούς και διαφορετικούς παράγοντες. Εν κατακλείδι, με βάση το υλικό που εξετάσαμε, η παρουσία της ‘μυκηναϊκής κοινής ́ δε διατρέχει το σύνολο της παραγωγικής διαδικασίας, αλλά εντοπίζεται σε ορισμένους άξονες της παραγωγής.
Artificial and Post-Artificial Texts
Authors: Bajohr Hannes
Published: April 2023

In contrast to the times of Höllerer and Zemanek, we are now truly on the threshold of being surrounded by texts that are entirely artificial—while at the same time we continue to merge with our language technologies in our own writing, so that our text production is increasingly supported, extended, and partially taken over by assistance systems. Therefore, I want to discuss—quite speculatively, but always with an eye on the state of the art—two questions: first, what happens when we are confronted with artificial texts in addition to natural ones? How do we read a text that we can no longer be sure was not written by an AI? And second, what direction might this development take if, at some point, the distinction between natural and artificial itself becomes obsolete, so that we no longer even ask about it and instead read post-artificial texts?

AN EXPERIMENTAL ANALYSIS OF THE PHENOMENON OF DELETION OF THE CONSONANT R IN BAICHENG COUNTY DIALECT OF MODERN UYGHUR LANGUAGE BASED ON FIELD SURVEY
Authors: ALIMU ABUDOUWAILI , KAILIBINU
Published: April 2023

One of the contextual variations in the Uyghur language stream is the deletion of vowels, which leads to long vowelization. However, in Baicheng county dialect of modern Uyghur language, apart from the long vowelization of vowels resulting from the deletion of consonants, there is also the phenomenon of non-long vowelization of vowels. If the individual words resulting from the deletion of the consonant [r] is used alone, it may have the effect of distinguishing meaning, but when the word is used in the groups of words, phrases or sentences, it returns to its pre-deletion meaning according to the context and does not have the effect of distinguishing meaning.

RESEARCH ON THE REFORM PATH OF SUB-DISTRICT OFFICES FROM THE PERSPECTIVE OF HOLISTIC GOVERNANCE—A CASE STUDY OF BIJIASHAN SUB-DISTRICT OFFICE IN THE SHUSHAN DISTRICT OF HEFEI CITY, ANHUI PROVINCE
Authors: ZHU XIANGQI
Published: April 2023

As the key subject of grassroots governance, sub-district offices are imperative to the society’s smooth operation and cities’ healthy development. In practical grassroots governance, sub-district offices inevitably have some drawbacks, such as jumbled institutions, chaotic personnel, and inefficient function implementation, overlapping other organizations or institutions with unclear rights and responsibilities. From the perspective of holistic governance, this paper takes the reform of the Bijiashan Subdistrict Office in the Shushan District of Hefei City as a research case, exploring its reform path and summarizing its practical achievements. After the reform of the Bijiashan Sub-district Office, the structure of horizontal departments is reorganized, and the functions are optimized. In addition, the responsibilities and relationships of its vertical departments turn clear, with the unimpeded instructions issued by the Party Committee. Besides, the feedback from grassroots governance becomes timely and effective, which constitutes a new pattern characterized by “communication from top to bottom, horizontal linkage, stereo alternation, and collaborative governance”. As an epitome of grassroots governance, the reform of the Bijiashan Sub-district Office is helpful to improve and develop the socialist system with Chinese characteristics and promote the modernization of the national governance system and governance capacity.
THE TEXTUAL PRACTICE OF AMATEUR GAMES: ANALYSIS OF ROLAND BARTHES' RESCUE OF THE LEGITIMACY OF THE WRITING SUBJECT
Authors: LI ZIBIN
Published: April 2023

As the core way of Roland Barthes's late textual practice, "amateur" always rejects the ideological power of discourse construction, especially the power collapse within the language system, and tries to break the long-standing "intransitive" dilemma of writing through a non-utilitarian textual game. However, it also shifts the responsibility of narrative to social structures and releases a sense of lost historical disillusionment. Based on the textual manifestation of the concept of "amateur", including its position, goals and other specific forms of practice, and combined with the relevant research on modern symbolic media, this paper will explore Barthes's legitimacy argument against the writing subject, as well as the intimate connection between the text and the author in the practice of "amateur". In this way, we explore Barthes' argument for the legitimacy of the writing subject and the intimate connection between text and subject in "amateur" practice.

Authors: WEI JIXIN , WU YAN
Published: April 2023

The rise of the Internet and big data has realized the digitization of the cultural industry, accelerated the promotion of cultural and literary works on the Internet, and expanded its scope of influence. At the same time, its development has also aggravated the long-standing moral issues in the cultural industry, such as privacy leakage, data theft, copyright infringement, etc., which seriously hinder the healthy development of the cultural industry. Based on the Internet, multi-node composition and decentralization, the blockchain, as a distributed ledger system, has the characteristics of “decentralization”, equal node status, de-third-party trust, and difficult data tampering and forgery. Its application will bring great value in cultural industry management. At the same time, as a new type of technical structure combination, the application of blockchain in the field of cultural industry is not achieved overnight, and there are certain technical obstacles in itself, and the relevant regulations have not yet been constructed, which need to be studied and solved urgently. Based on the dilemma of the network cultural products dissemination protection, this paper introduces the blockchain certificate technology, hoping to realize the new trend of the protection of network cultural products dissemination by building an excellent blockchain network cultural product protection model, technical approach, regulatory system and rule system.
Exponential Single Server Queues in an Interactive Random Environment
Authors: Otten Sonja , Krenzler Ruslan , Daduna Hans , Kruse Karsten
Published: April 2023

We consider exponential single server queues with state-dependent arrival and service rates that evolve under influences of external environments. The transitions of the queues are influenced by the environment’s state and the movements of the environment depend on the status of the queues (bidirectional interaction). The environment is constructed in a way to encompass various models from the recent Operations Research literature, where a queue is coupled with an inventory or with reliability issues. With a Markovian joint queueing-environment process, we prove separability for a large class of such interactive systems; that is, the steady state distribution is of product form and explicitly given. The queue and the environment processes decouple asymptotically and in steady state. For nonseparable systems, we develop ergodicity and exponential ergodicity criteria via Lyapunov functions. By examples we explain principles for bounding departure rates of served customers (throughputs) of nonseparable systems by throughputs of related separable systems as upper and lower bound.
Approach to the orthopaedic patient
Authors: Jaworski Janek , Dudley Robert
Published: April 2023

Approaching orthopaedic patients represents a common challenge for first opinion practitioners. Knowledge and understanding of the correct steps necessary to narrow down the list of differential diagnoses, and selection of appropriate diagnostic modalities, is crucial to success. The approach to orthopaedic patients should comprise obtaining a history, observing the standing patient, gait analysis, orthopaedic examination and a brief neurological examination. Orthopaedic examination can be separated into palpation and manipulation. This methodical approach allows the clinician to avoid the common mistakes of delayed diagnosis and subsequent owner dissatisfaction. This article will focus on a methodical approach to orthopaedic patients, with particular attention on the common challenges encountered by first opinion practitioners.

The objective of this study was to determine the effects of deficit of ankle dorsiflexion in athletes who sustained a chronic lateral ankle sprain to the hopping performance. A comparative study was designed to compare the deficit and non-deficit condition of ankle dorsiflexion as a result of the weight bearing lunges test to distance hopping ability with single leg hop, which was normalized with leg length. There were no statistically significant differences in hopping performance, deficit vs non-deficit ankle dorsiflexion within-group comparisons in males (P = 0.932) or females (P = 0.999). Between group comparisons showed that ankle dorsiflexion deficit among female resulted lower hopping performance compared to male with / without ankle dorsiflexion deficit (P = 0.041 and P = 0.039). Surprisingly, hopping performance among male with ankle dorsiflexion deficit was further than female without ankle dorsiflexion deficit (P = 0.044). Meanwhile, hopping performance between male versus female without ankle dorsiflexion deficit were not significant (P = 0.054). The deficit of ankle dorsiflexion had no influence on hopping performance in athlete with a history of LAS, both male and female. Sex influenced hopping performance in athletes with ankle dorsiflexion deficits, with female athletes performing worse than male. During recovery, there might be differences in biomechanical adaptation between ankle dorsiflexion deficit conditions in female athletes compared to male.

The color of fresh-cut fruits is indicated by the appearance and quality of their products. A sliced apple is a highly putrefying fruit that is sensible to react with oxygen gas, which causes the color, taste, smell, and nutritional value to change during storage in ambient air. Non-thermal atmospheric pressure plasma jet (NTAPPJ) is one of the most crucial applications for food preservation. This study was divided into two parts. First, the emission intensities of the plasma spectrum and electrical properties were investigated. Then, the colorimetric was used to investigate plasma-treated effects on different liquids (tap water, deionized water, and saline water) to delay color changes of fresh-cut apples. The I-V characteristic curve was used to obtain an optimal power of 8.5 kHz-AC pulse-driven NTAPPJ with argon gas. Additionally, the parameter a*, L*, b*, ΔE, h*, YI, Chroma, and browning index (BI) using the colorimeter method were examined. We then demonstrated that using the Ar-NTAPPJ can be considered a novel approach to increasing fresh-cut apple’ toleration and shelf life. Furthermore, plasma exposure is one of the nondestructive processes that does not have any side effects on the products and can significantly delay degradation and discoloration.

We examined recovery of bryophyte diversity during forest restoration by the framework species method (FSM), as a component of overall biodiversity recovery—one of the defining indicators of restoration success. The epiphytic bryophyte communities in FSM trial plots (13 and 21 years since tree planting), were compared with those of old-growth forest in the upper Mae Sa Valley, northern Thailand. Bryophytes were surveyed in June 2019, on the bark of 3 framework tree species: Archidendron clypearia, Erythrina subumbrans and Sarcosperma arboreum. Fifteen species were recorded, representing 14 genera and 12 families in 3 morphological groups: acrocarpous mosses 4 species (27%), pleurocarpous mosses 5 species (33%) and leafy liverworts 6 species (40%). Within 13 years after restoration initiation, bryophyte species richness had increased to the same level as that recorded in old-growth forest. Furthermore, the bryophyte community species composition of the older restoration forest was more similar to that of natural forest than was the bryophyte community species composition of younger forest. We conclude that the FSM effectively recovers bryophyte diversity and directs the successional trajectory of the bryophyte community towards that of old growth forest within an acceptable time span. The use of bryophytes as indicators of forest restoration progress is discussed. Keywords: Conservation, Framework species method, Liverwort, Moss, Species richness

In recent years, natural pigments are replacing synthetic colourants due to their undesirable side effects. Microorganisms are a major source of natural colours and can produce a variety of pigments that have high value in food and textile industries. In the present work, the isolation of a novel microbe capable of producing a stable and high intense red pigment and its optimization is attempted. In this study, purification, characterization and optimization of pigment production by a bacterium isolated from the anthill soil are reported. The bacterial isolate was biochemically identified as Micrococcus sp., and was confirmed with 16S rRNA gene sequencing. The effects of carbon and nitrogen source, temperature, pH and oxygen availability on pigment production were investigated. Optimum growth was observed with a pH 6 and 5% glycerol and incubation at 28°C at 220 RPM. Three pigments were extracted and purified by column chromatography. The extracted red pigment was characterized using UV-visible, Mass and NMR spectroscopy and was confirmed as the carotenoid, echinenone (beta, beta-Caroten-4-one). After optimization, a yield of 25.98 mg/L of total carotenoid was produced by Micrococcus sp. The extracted carotenoid pigment can be used as natural colouring agent in food and textile industry.

Migrant workers from Myanmar living in Thailand have significantly increased, these migrant workers may display health risk of common bacterial infections and host immune response of Myanmar workers to those common bacterial infections is still not well known. In this study, we observed antibodies and interferon-gamma to the common bacteria causing sepsis in this area, such as Escherichia coli, Klebsiella pneumonia and Pseudomonas aeruginosa including Burkholderia pseudomallei which is pathogenic and endemic in this area. The results showed that Myanmar workers decreased cellular function of interferon-gamma response, compared with native Thai workers. But the humoral response of human IgG showed no significant difference between Myanmar and Thai workers. Even though E. coli and K. pneumonia induced lower level of plasma IgG response than the other two bacteria, but host plasma could effectively kill and clear the bacteria within an hour in vitro. Interestingly, the level of anti-Hcp 1, which is a diagnostic marker for B. pseudomallei, was low in Myanmar workers suggesting no exposure to this organism. However, the sample size should be increased to reach the conclusion. Our study could provide useful information for Myanmar migrant workers to promote safe working and awareness of health risks to bacterial infections.

Bignay (Antidesma bunius (L.) Spreng) is a fruit-bearing tree that is indigenous to the Philippines and in different parts of Asia with bignay-common and bignay-kalabaw as the two most locally abundant cultivars. Its fruits are being consumed as food and have been recently studied for its antioxidant properties. However, several chemical constituents of bignay fruit are still yet to be explored. Therefore, this study aimed to determine the vitamins, minerals, and phytochemicals present in bignay-common and bignay-kalabaw fruit. Using HPLC analysis, bignay-kalabaw was observed to have higher vitamin A and E contents than bignay-common. On the other hand, bignay-common was higher in terms of vitamin C content with 25.996 ± 0.688 mg/100 g freeze-dried fruit compared to bignay-kalabaw. Mineral analysis using ICP-OES revealed that bignay-kalabaw fruit had more calcium, copper, and manganese content than bignay-common. Conversely, bignay-common had significantly higher iron content than bignay-kalabaw. Qualitative screening using methanolic extracts revealed that both cultivars possessed 9 out of the 14 phytochemicals tested, namely tannins, saponins, flavonoids, quinones, terpenoids, phenols, coumarins, steroids, and phlobatannins. The findings obtained in the present study indicate that the fruits of these bignay cultivars contain health-promoting compounds and have potential to be used as food supplements. Further in vitro studies for the two bignay cultivars are recommended. Keywords: Antidesma, ‘Common’, ‘Kalabaw’, Nutritional, Phytochemical

This study aimed to investigate the biological activities, cytotoxicity, phytochemical constituents and stability profile of Bouea macrophylla Griff. peel extracts for cosmeceutical applications. Extraction using maceration or fractionation was optimized using various solvents; ethyl acetate, ethanol, 50%v/v ethanol. The antioxidant activities were determined using DPPH and ABTS radical scavenging, lipid peroxidation inhibition and FRAP assays. Anti-tyrosinase activity was also performed for implying skin depigmentation effects. Total phenolics content, total ﬂavonoids content and total anthocyanin content were also investigated. In addition, ex vivo cytotoxicity and anti-inflammatory effects of the selected extract were studied. Moreover, high performance liquid chromatography (HPLC) technique was used to analyze and quantify phytochemical components of the extract to study the stability profile. The results revealed that the highest percentage yield was shown in hydroethanolic extract (BPHE). Regarding phytochemical contents, BPHE contained 83.91 ± 0.00 mg gallic acid equivalent (GAE)/g extract, 12.98 ± 0.01 mg quercetin equivalent (QE)/g extract. Additionally, BPHE exhibited the strongest antioxidant and anti-tyrosinase properties along with good anti-inflammatory effects. Furthermore, BPHE had no cytotoxicity to human fibroblast cells. The HPLC results showed two major peaks in BPHE, i.e., gallic and ellagic acids. Accordingly, B. macrophylla peel extract could be a promising bioactive ingredient to develop further as anti-aging cosmetic and cosmeceutical products.
