Microbiologically Contaminated and Over-Preserved Cosmetic Products According Rapex 2008-2014
No full textWe investigated the Rapid Alert System (RAPEX) database from January 2008 until week 26 of 2014 to give information to consumers about microbiologically contaminated cosmetics and over-preserved cosmetic products. Chemical risk was the leading cause of the recalls (87.47%). Sixty-two cosmetic products (11.76%) were recalled because they were contaminated with pathogenic or potentially pathogenic microorganisms. Pseudomonas aeruginosa was the most frequently found microorganism. Other microorganisms found were: Mesophilic aerobic microorganisms, Staphylococcus aureus, Candida albicans, Enterococcus spp., Enterobacter cloacae, Enterococcus faecium, Enterobacter gergoviae, Rhizobium radiobacter, Burkholderia cepacia, Serratia marcescens, Achromabacter xylosoxidans, Klebsiella oxytoca, Bacillus firmus, Pantoea agglomerans, Pseudomonas putida, Klebsiella pneumoniae and Citrobacter freundii. Nine cosmetic products were recalled because they contained methylisothiazolinone (0.025%–0.36%), benzalkonium chloride (1%), triclosan (0.4%) in concentrations higher than the limits allowed by European Regulation 1223/2009. Fifteen products were recalled for the presence of methyldibromo glutaronitrile, a preservative banned for use in cosmetics. Thirty-two hair treatment products were recalled because they contained high concentrations of formaldehyde (0.3%–25%)

Akamaro k’Indirimbo mu Gutoza Kuvuga Neza no Kunguka Amuga mu Rubumbambaga Nyarwanda: Urungano n’Igipimo cy’Urukundo za Rugamba Cyprien
No full text“Akamaro k’indirimbo mu gutoza kuvuga neza no kunguka amagambo mu rubumbabaga nyarwanda: Urungano n’igipimo cy’urukundo za Rugamba Cyprien” (The Impact of Songs in Teaching the Art of Speaking Well and Acquiring Vocabulary in Rwandan Society: Urungano and igipimo cy’urukundo by Rugamba Cyprien) is a study guided by the general objective of evaluating the contribution of songs in teaching effective public speaking and enriching vocabulary within the Rwandan community. To achieve the set objectives, we selected two literary works by Rugamba Cyprien: Urungano and igipimo cy’urukundo. The methodology used to analyze these works was based on a literary criticism approach known as ijoranyandiko. Following the selection of the case studies, we applied different methods—namely umunozo, ikeshamvugo, isesengurangingo, and isesengurantego—to support our literary analysis and help us reach our goals. Through the analysis, we found that these songs promote values such as love, peace, and harmonious living within Rwandan society. The results of our study confirmed that the objectives were successfully met. Indeed, Rugamba Cyprien significantly contributed to fostering a culture of love, peace, and tolerance among Rwandans. This is clearly reflected in both songs, where the author emphasizes that love is fundamental to human relationships. One of the recommendations drawn from our findings is that students should form clubs dedicated to promoting Cyprien Rugamba’s literary works within Rwandan society

This study examines the impact of the green campus program at
higher education institutions on students' environmentally friendly
behavior and its contribution to sustainable development on campus
and in surrounding communities. The green campus initiative
addresses global environmental concerns by promoting responsible
policies and behaviors. A quantitative approach was used, with data
analysis conducted using Orange Data Mining software. The sample
comprised 500 respondents from various study programs at the
Faculty of Tarbiyah and Teacher Training, including environmental
ambassador students at the State Islamic University of Raden Intan
Lampung. Results showed positive perceptions of waste
management facilities (mean = 4.04; SD = 0.9) and environmentally
friendly transportation (mean = 3.68; SD = 1.03). However, pro
environmental behavior remained uneven, influenced by personal
and institutional factors. The study recommends enhancing
environmental education and support facilities to improve the
program’s effectiveness. These findings offer strategic insights for
other institutions implementing green campus initiatives
The phytochemistry of Ganoderma species and their medicinal potentials
No full textThe Ganoderma genus is known for its diverse use as a functional food and therapeutic agent. This fungus has over 428 species, with Ganoderma lucidum being the most studied. The Ganoderma species produce several secondary metabolites and bioactive compounds like polysaccharides, phenols, and triterpenes, which are largely responsible for their therapeutic properties. Throughout this review, several extracts obtained from Ganoderma species have been studied to delve into their therapeutic characteristics and mechanisms. Such properties like immunomodulation, antiaging, antimicrobial, and anticancer activities have been demonstrated by several Ganoderma species and are supported by a large body of evidence. Although its phytochemicals play a vital role in its therapeutic properties, identifying the therapeutic potentials of fungal-secreted metabolites for human health-promoting benefits is a challenging task. Identification of novel compounds with distinct chemical scaffolds and their mechanism of action could help suppress the spread of rising pathogens. Thus, this review provides an updated and comprehensive overview of the bioactive components in different Ganoderma species and the underlying physiological mechanisms.peer-reviewe
St. Maximus the Greek (Mihail Trivolis, Arta, ca. 1470–Maksim Grek, Moscow, 1556): The Insight into His Personal Euchology
No full textThis text establishes a datum for claims that Maximus the Greek’s life-work was to protect and preserve ancient precepts for a personal devotional “space” against statist and imperial imprimatur. This task was accomplished through both his work as translator and as author of sacred devotional texts and hymns associated with Byzantine hymnography and the Eastern Orthodox Christian tradition. Notably, it is his inner veneration of the Holy Theotokos that marks the primary sensibility of the defence of this intense, inwardly-focused faith in direct communion with the Divine. Maxim’s defence of the Eastern Orthodox Christian tradition was accomplished by the special guidance of the Holy Spirit as his personal internal principle that he used not only in the prayer (hesychastic, ascetical) and in the theological works (hagiographical, liturgical), but also in the philological works (of editing, translating, redacting), and especially in the exegetical texts.
Therefore, the strong Byzantine patristic and monastic thought as the basis of his contemplative practice, formed in the years spent at the Holy Mount Athos, were only one of the one of the important sources of his original Orthodox theology.
Into detailed consideration are taken especially his prayers. Among them, the most important place is reserved for “The Kanon to the Holy and Divine Spirit Parakletos,” which reflects several possible influences, such as the Akathystos hymn, the Great Kanon, and the individual canon as was St. Constantin’s Kanon to St. Demetrius, all of which confirm the very archaic Byzantine and Slavonic sources that properly could serve Maxim for his Old Church Slavonic linguistic basis. Thus, his prayer is a highly original, monastic and deeply personal work that bears witness to his ascetic (hesychastic) practice. All of this tends to confirm that his grammatical and linguistic view of the Old Church Slavonic language was shaped well before his entrance to Muscovite Russia, and that not only was he unjustly accused of heretical mistakes, and thereby imprisoned, but he was, more importantly, completely misunderstood. Nevertheless, and despite his suffering, Maxim was, until the end of his life, arguing that his use of Slavonic language was guarded and, therefore, sacred
