Due to the risks regarding long-term antibiotic resistance development of pathogenic bacteria in humans, the utilization of synthetic antimicrobials in livestock feed has been banned in most animal production practices. However, antibiotic prohibition in livestock can result in poor performance of the animals in terms of yield of production, quality, and health status. Therefore, it is important to find natural alternatives such as propolis to substitute for antibiotic usage in livestock feed. Propolis is a natural resin produced by honeybees. There are over 300 beneficial compounds found in propolis. It contains various bioactive compounds such as flavonoids, phenolic acids, and others which contribute to its antimicrobial, antifungal, and antioxidant properties. Various studies have been carried out to determine the biological and chemical activities of propolis as well as its function as an alternative natural feed additive. Thus, this review focuses on propolis composition, the potential of stingless bee propolis in Borneo, its potential as an antioxidant with antimicrobial properties, and the potential of propolis as a natural feed additive for poultry.","PeriodicalId":18160,"journal":{"name":"Malaysian applied biology","volume":" 22","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139137921","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A ‘broken-stick’ linear regression of heading rate against photoperiod was used to determine the cardinal photoperiods for heading.  The reproductive development towards photoperiod showed a delayed pattern in time to heading, anthesis, and maturity under lengthening photoperiod from 10 to 12 h.  For example, under 10 h photoperiod the crops required 1680 °Cd (70.8 days) from emergence to heading but took an extended duration of 3147 °Cd (132.6 days) when they were sown at 12 h photoperiod. The prolonged time taken for reproductive development modified by photoperiod resulted in higher yield components. This is because the lengthening time from heading to maturity extended the duration of grain filling. The longest photoperiod of 12 h gave the highest percentage of filled spikelets (65.3%) thus consequently leading to the heaviest grain weight of 1.4 g per panicle. The base, optimum, and maximum photoperiod for heading were estimated to be 7.4 h, 10 h, and 14.8 h, respectively.","PeriodicalId":18160,"journal":{"name":"Malaysian applied biology","volume":" 55","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139137958","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Hence, this study investigates the content of macronutrients, micronutrients, phytochemical constituents, total phenolic content (TPC), total flavonoid content (TFC), and antioxidant properties in the aqueous leaf extract of this plant. The study found that N. oleracea leaves were possessed with high fiber (52%), moisture (23.33%), fat (5.33%), protein (5.25%), carbohydrate (6.42%), ash (7.67%), and mineral content with a sequence of Potassium > Calcium > Sodium > Phosphorus. A positive result of tannins, steroids, phenols, and flavonoids were detected. High values of TPC and TFC which were 136.19 ± 0.62 mg GAE/g and 829.17 ± 19.09 mg GAE/g of dry weight respectively were obtained. Meanwhile, the hydrogen peroxide scavenging activity of the plant extract produced an IC50 of 70.09 µg/mL. The presence of a high content of polyphenolic compounds may reflect the antioxidant properties of this plant. In conclusion, the aqueous extract of N. oleracea leaves showed the presence of various phytochemical constituents and has a high content of TPC and TFC which may be derived from its nutritional content.  Hence, consumption of N. oleracea leaves is useful for human health and disease prevention.","PeriodicalId":18160,"journal":{"name":"Malaysian applied biology","volume":" 42","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139141668","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study aims to shift the paradigm of using glutathione as a whitening agent into a potent antioxidant for therapy, particularly for ethanol-induced teratogenesis in the Philippines. Zebrafish embryos were treated with glutathione at various time points of ethanol exposure and concentration. Pre-treatments, co-treatments, and post-treatments with 100 μM glutathione solution were done to assess the most appropriate time point for glutathione intake upon exposure of the embryo to ethanol. Eye diameter and otic vesicle diameter were chosen as morphological parameters because dysmorphogenesis of these organs resembles mammalian fetal alcohol syndrome disorders. For eye diameter, alleviation of microphthalmia by glutathione was seen in pre-treatment (1% ethanol only) and post-treatment (1% & 1.5%) while co-treatment did not exhibit rescue for eye diameter reduction. For otic vesicle diameter, pre- and co-treatment with glutathione did not exhibit any changes in size but post-treatment showed abnormal enlargement suggesting possible teratogenic effect across all ethanol concentrations. The 2,2-diphenylpicryl-1-hydrazine (DPPH) assay was used as a confirmatory test for the free radical scavenging activity (FRSA) of treated tissues. Pre-treatment with GSH at 1% ethanol showed the highest FRSA while post-treatment showed FRSA insignificantly different to controls. This study suggests that glutathione can alleviate oxidative stress in embryo development which may lead to dysmorphogenesis and that supplementation before and after ethanol exposure may be a viable form of therapy for ethanol-induced teratogenesis.","PeriodicalId":18160,"journal":{"name":"Malaysian applied biology","volume":" 25","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139139923","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, it is believed that the preservation of Japanese koi sperm by short-term storage and cryopreservation could solve this problem. In this study, the appropriate diluent solution, sperm-to-diluent ratio, and storage temperature for short-term storage of Japanese koi sperm were determined, and the efficacy of the short-term stored sperm in fertilizing eggs was evaluated. Milt samples collected from sexually mature males were pooled and tested in modified calcium-free Hank's Balanced Salt Solution (CF-HBSS), modified Mahseer extender, and modified Kurokura extender at 1:1 and 1:5 ratios of sperm to diluent, respectively. Storage temperatures were tested at 4 °C and room temperature. Milt sample without diluent solution served as a control. The percentage of sperm motility was measured daily for one week. For the egg fertilization experiment, Japanese koi eggs were fertilized with sperm on the second day of short-term storage, while a freshly collected sperm sample served as a control. We found that sperm diluted 1:1 with a modified Kurokura extender and stored at 4 °C had a mean sperm motility of 76.00 ± 3.06% on the third day, compared with 54.67 ± 2.91% in the control treatment (P<0.05). Short-term stored spermatozoa showed equivalent egg fertilization ability compared to fresh spermatozoa (control) (P>0.05). In conclusion, the use of a modified Kurokura extender at a 1:1 ratio of sperm to diluent and storage at 4 °C was optimal for short-term storage of Japanese koi sperm, and these sperm still showed equivalent egg fertilization ability to freshly collected sperm after two days of storage.

This indigenous species has yet to be fully explored for its nutritional and phytochemical properties. Hence, the present study aims to evaluate the nutritional compositions and phytochemical properties of A. odoratissimus fruit. The nutritional and phytochemical properties of A. odoratissimus vary across its parts. The edible flesh and seeds exhibited higher carbohydrate content at 12.16±1.01% and 9.96±0.76%, respectively. Seeds possessed significantly higher crude protein (21.89±0.54%) and fat (18.23±0.20%).

Potassium (905.61±18.89 to 2001.51±13.00 mg 100 g-1) was the most abundant in A. odoratissimus fruits, followed by calcium (578.30±7.00 to 1300.97±23.51 mg 100 g-1). The flesh is primarily composed of non-reducing sugars, including fructose (26.70±0.70 g 100 g-1) and glucose (25.38±0.45 g 100 g-1), with a notable amount of vitamin B1 (11.07±0.31 mg 100 g-1). The seed oil contains essential fatty acids, with a significant proportion of unsaturated fatty acids (57.10%), mainly nervonic acid (45.32%). The pedicel, often considered a by-product, exhibits relatively high levels of phytochemical properties in comparison to the edible portions.
