While for nanocrystalline the size ranged (from 9.395- 206) nm. Several phytochemicals were detected within algal extracts such as phenols, tannins, alkaloids, flavonoids, resins, and saponins. All these active compounds participated in nano-synthesis by acting as reducing and stabilizing agents. finally, titanium nanoparticles were used as a controlling agent against house flies (Musca domestica) and compared with traditional insecticides (Imidacloprid). High mortality percentages reached 100% against 1st larval stage, 70% against 3rd larval stage, and 93.3% in adult flies. These fatalities were higher after using Imidacloprid for all tested stages. Many phenotypic distortions were also caught in houseflies treated with TiO2 NPs prepared by Chlorella, such as; failure in pupal emergence and maturity, incomplete development in the head, legs, and wings, and disappearance in genital organs.

These technologies provide an excellent opportunity to produce biomass and bioactive compounds from plants, especially Gynura procumbens. Previous reports mentioned a small-scale bioreactor could increase biomass and bioactive compounds of G. procumbens adventitious roots. Therefore, a larger bioreactor for adventitious root culture is necessary to develop. In this study, the development of the 19 L pilot bioreactor was successful. The optimal condition for bioreactor sterilization is 1.8 bar for 60 min using an autoclave. We found that G. procumbens adventitious roots culture in pilot bioreactors has resulted in optimal biomass using MS-Tek media (technical grade) compared to MS-PA (pro analyze) media after 35 d of the culture period. Although, higher productivity of total phenolics and total flavonoids in G. procumbens roots has been achieved from MS-PA media rather than MS-Tek media. In further study, it is necessary to evaluate the effect of technical-grade chemicals on kinetics root growth and chemical uptake.

Doxorubicin, for example, increases the level of reactive oxygen species (ROS), leading to cell senescence in the kidneys. Cardamom essential oil (Amomum compactum Soland. ex Maton) contains compounds that exhibit antioxidant activity, such as 1.8-cineole, α-pinene, α-terpineol, and linalool. This study focused on exploring the potency of cardamom essential oil (CEO) as an anti-senescence induced by doxorubicin using Vero cells. CEO was obtained by steam distillation. The cytotoxic assay was carried out using trypan blue exclusion assay. We performed the 2',7'-dichlorodihydrofluorescein diacetate (DCFDA) staining and the senescence-associated beta-galactosidase (SA-β-gal) staining to measure the effect of CEO on intracellular ROS level and cell senescence, respectively. Analysis of the compounds with gas chromatography-mass spectrophotometry (GC-MS), revealed seven compounds with significant abundance, namely 1.8-cineole (50.82%), ß-pinene (12.43%), α-terpineol (8.50%), fenchone (4.10%), α-pinene (4.00%), sabinene (3.00%), and linalool (1.98%). The cytotoxicity assay of CEO on Vero cells showed an IC50 value of 178 μg/mL. Thus, the CEO is considered to be not cytotoxic and safe for normal kidney cells. Concentrations of 50 and 100 μg/mL reduced the senescence induced by doxorubicin. Therefore, the CEO has the potency as a nephroprotective agent in doxorubicin-induced senescence.

The leaves of S. trifasciata show antibacterial properties against Pseudomonas aeruginosa. This bacterium is an opportunistic pathogen that can cause serious illness in humans and produce a variety of virulence factors responsible for bacterial pathogenesis with quorum sensing (QS) systems that mediate intracellular communication. Bacteria produce protease through a QS mechanism in which they express signaling molecules to become pathogens. Proteases are extracellular enzymes required for successful infection that mediate biofilm spread through QS and regulate a variety of cellular and physiological functions. This research aimed to evaluate the protease, and anti‐QS activities of the ethanolic extract from S. trifasciata leaves against P. aeruginosa and the expression of QS genes. An azocasein test was used to determine the protease activity in qualitative and quantitative methods. Using real‐time quantitative polymerase chain reaction, a study was conducted to investigate the effect of ethanolic extract from S. trifasciata leaves on selected QS‐regulatory genes at the transcriptional level. The results showed that the potential ethanolic extract from S. trifasciata leaves inhibited the protease enzyme activity by as much as 77.1%.

Chitinase was produced by fermentation in colloidal chitin broth at 40 °C, pH 7, for 7 days, while chitinase activity was checked every 24 h. The optimal fermentation time was used to produce chitinase for a further purification step. Enzyme purification was carried out by ultrafiltration, ammonium sulfate precipitation, ion exchange chromatography (Q Sepharose Fast Flow), and gel filtration (Sephacryl S‐300).

We successfully cloned into the pET vector system and expressed the recombinant LLM2 in Escherichia coli BL21(DE3). The recombinant LLM2 was overproduced and purified in the form of an inclusion body with a molecular weight of ±39.5 kDa when it was analyzed in 15% SDS‐PAGE.

The refolded recombinant LLM2 exhibited a strong spectrum at 205 nm, while the unfolded recombinant LLM2 did not. The Tm, ΔHTm, and ΔSTm values of the refolded recombinant LLM2 were determined to be 318.31±4.4 K, 11.76±1.3 kJ.mol‐1, and (3.74±0.48)x10‐2 kJ.mol‐1.K‐1, respectively.

This research aimed to characterize long non‐coding RNA (lncRNA) from bananas that may have roles in regulating gene expression related to the disease response mechanism in banana derived from transcriptomic libraries. Furthermore, the detected transcripts were analyzed to identify the endogenous target mimics (eTMs) interaction between lncRNA and microRNA (miRNA) using computational approaches. Data from Cavendish banana (AAA group), Berangan (AAA group), Yunnan Banana (Itinerans), Dajiao (ABB group), and Klutuk (BB group) were used in this research. We found that lncRNA tends to be unsustainable, and most sizes are below 1000 bp (≥ 75%). Based on this result, we investigated the eTMs to determine lncRNA transcripts and miRNA, such as miR397 in Cavendish and miR444 in Klutuk.

Thus, characterization of the virus strains from Indonesia is important. GISAID, NCBI BLAST, and MAFFT version 7 were used. There were 9,488 isolates in Indonesia as of November 2021, with the majority including the Delta variant. While most of the isolates have mutations common to those from other countries, there are some atypical ones, such as mutation V1264L in the Delta variant that was suspected to play a role in worsening the pandemic. The Delta variant had the most mutations in the spike protein when compared to the Alpha and Beta variants, giving it important roles in infectivity and vigorous entry into cells, with some general clinical manifestations like fever and sore throat; however, the severity of the Delta variant is attributable to its rapid growth.
