Characterization of metabolic features derived from the non-polar metabolite UHPLC-QTOF dataset of Jaspis sp. Collected from the waters off Pulau Banggi, Sabah, Malaysia
No full textThe marine biome is a rich source of bioactive compounds. The discovery of anti-cancer compounds in Cryptotheca crypta in 1950 initiated a wave of bioprospecting efforts focused on marine sponges. Jaspis sp., a marine sponge, has been reported to exhibit anti-cancer activity against human colorectal cancer. A sample of Jaspis sp., collected from the waters off Pulau Banggi, Sabah, Malaysia, was analyzed through a non-polar metabolite survey. The non-polar crude extract was profiled using UHPLC-QTOF in both positive and negative modes. The detected metabolic features were clustered, and representative features were tentatively identified through a combination of spectral database searches (using various MS2 spectral databases) and in silico compound identification. This dataset provides a valuable foundation for future bioprospecting endeavors involving Jaspis sp
The impact of Jin Shangyi's oil painting education on contemporary art pedagogy
No full textJin Shangyi is one of the important founders of Chinese oil painting education and the first generation of oil painters trained after the founding of New China. The history of Chinese oil painting is very short. Whether from the exploration of his own profession or the development of Chinese art education, Jin Shangyi advocates starting from the reality of Chinese oil painting, linking artistic creation with life, combining China's excellent traditional culture with the innovation of oil painting art, and moving forward steadily on the premise of constantly consolidating basic skills. Mr. Jin has profoundly influenced the development of Chinese oil painting education and promoted the process of nationalization of Chinese oil painting. This paper aims to explore the continued influence and value of Jin Shangyi's educational philosophy in contemporary art education, provide a model for contemporary art education to balance tradition and innovation, techniques and expression, and provide important inspiration for the growth of young artists
Hematological and blood biochemical variations, and their correlation with body condition in wild-foraging sea turtles of the Celebes sea
No full textThe Celebes Sea provides critical foraging and migratory habitats for sea turtles in Malaysian waters, yet health status data, including hematologic and blood biochemistry parameters, remain scarce. To address this gap, we examined the blood profiles of green turtles and hawksbill turtles in these foraging grounds. Physical assessments such as body condition scores and indices suggested overall clinical health, though one green turtle exhibited fibropapillomatosis, and a new occurrence of the burrowing barnacle Chelolepas cheloniae was observed on the carapace. Blood samples from 32 green turtles and 4 hawksbill turtles were analyzed using an iSTAT handheld blood analyzer, showing interspecific differences in blood values. Hawksbill turtles exhibited higher blood urea nitrogen concentrations, possibly due to their high-protein diet, while one green turtle showed abnormal blood profiles indicative of potential acidosis. This study provides baseline health data for foraging sea turtles in the Celebes Sea, emphasizing the importance of hematological and biochemical monitoring in assessing health status and informing targeted conservation strategies to address threats in their foraging habitats. These findings help us better understand sea turtle health and support efforts to protect these important species and their habitats

Unique mutations in non-structural proteins among sars-cov-2 Variants from Sabah, Malaysia
No full textNext-generation sequencing (NGS) is essential for monitoring SARS-CoV- 2 transmission and tracking of genomic evolution worldwide to identify the mutations associated with different infection rates. Sabah, Malaysia is the third-most populous state, accounting for approximately 10% of the country’s COVID-19 fatalities, underscoring the need for detailed genomic analysis of SARS-CoV-2 strains associated with this region. This study analysed 644 COVID-19 samples through whole-genome sequencing, supplemented by 1,458 additional Sabah COVID-19 sequences from the GISAID EpiCoV consortium. As of June 2024, samples from Sabah showed a 1:1 male-to-female ratio, with the highest representation in the 21-30 age group (n=404). The samples showed a relatively high mutation count, with a mode of 62 and an average of 56.9 mutations per sample. We documented 67,485 amino acid-changing SNP events (68.6% of the total), while silent SNPs represented 21.3% (20,918 events) and primarily occurred in the coding regions. Kota Kinabalu district has the highest mutation frequency, while Tawau district has the lowest. Although no distinct mutation pattern emerged across age groups, mutation frequency was generally high in individuals aged 0 to 25, followed by individuals aged 61 to 90 and those aged 26 to 60. Notably, ten unique coding mutations were identified, with A580P and S672P mutations in the NSP region affecting viral protein stability and rigidity. The presence of two unique mutations found in the Sabah population is absent from global databases like GISAID or Nextstrain, suggesting region-specific viral evolution. These mutations may have arisen due to local selection pressures and adaptation influenced by host genetics, transmission patterns, or therapeutic interventions. These findings provide valuable insights into the spread and evolution of SARS-CoV-2 strains in Sabah and the surrounding areas
Standardization of spawn and substrate formulations for morchella mushroom cultivation
No full textThe present study evaluated various cultural media and substrate formulations to optimize the cultivation of Morchella esculenta. Three culture media, Potato Dextrose Agar (PDA), Malt Extract Agar (MEA), and Czapek-Dox Agar (CDA), were tested for mycelial growth at 25°C over 3, 5, and 7 days. PDA proved most effective, supporting the fastest and most extensive mycelial expansion (8.4 cm by day 7), followed by MEA (7.2 cm) and CDA (5.4 cm), likely due to its nutrient-rich composition. For spawn production, three cereal grains, barley, wheat, and white sorghum, were assessed over 7, 14, and 21 days. Barley supported the most vigorous growth (9.0 cm by day 21), followed by wheat (8.0 cm) and sorghum (6.0 cm), suggesting barley offers optimal nutrition and texture for spawn development. Substrate evaluations without nutrient bags involved three formulations: Compost-Potting Soil-Sand, Hardwood Chips, and Sawdust. While all supported sclerotia and pinhead formation, none produced mature fruiting bodies. Hardwood Chips showed the best early development (5 fruiting bodies), yet nutrient limitations restricted full maturation. With nutrient bags, substrate performance improved. Soil + Wheat Straw yielded 20 fruiting bodies with the fastest development. Soil + Organic Matter + Peat Moss produced the highest number of fruiting bodies (22), though no mature mushrooms were harvested. The enhanced initiation stage with nutrient supplementation highlights its importance, but the absence of full maturation across treatments suggests environmental factors or micronutrient deficiencies may be limiting. Further refinement of growth conditions and nutrient inputs is necessary for successful Morchella cultivation
First record of endoparasite infestation in low value fish food in East Java, Indonesia
No full textThis research was conducted in Jawa Timur to provide information on the infestation of endoparasites in mackerel fish used as feed for grouper aquaculture. Low-value fish specimens were randomly collected from fish traders in the Karangploso market. These specimens were then analyzed in the laboratory. During collection, the specimens were stored in ice to maintain their integrity. Morphological measurements, including body weight and total length, were recorded, and the presence of parasites was observed. A total of 78 samples were collected and classified into two groups based on morphological observations: the yellowtail scad (Atule sp., n = 43) and the Indian mackerel (Rastrelliger sp.; n = 35). The length and weight of the samples were appropriate for use as feed. The prevalence of parasitic worms was found to be 7% in the yellowtail scad, categorizing it as an occasional infection. In contrast, no parasitic worms were detected in the Indian mackerel, classifying it as rare infection. Based on these findings, the two types of fish found in East Java are relatively healthy and suitable for use as feed for cultured grouper
