Sea anemones are an important source of bioactive compounds with potential pharmacological applications. Their toxins are produced and stored in organelles called nematocysts and act on specific targets, including voltage-gated ion channels. To date, sea anemone toxins have demonstrated effects on voltage-gated sodium and potassium channels, facilitating investigations into the structure and function of these proteins. In this study, we evaluated the effect of Bunodeopsis globulifera sea anemone crude extract, and of a low molecular weight fraction, on voltage-gated sodium and calcium channels within the murine nervous system. Notably, the crude extract led to a significant reduction in total sodium current, while also triggering calcium-dependent glutamate release. Furthermore, the low molecular weight fraction, in particular, enhanced total calcium currents and current density. These findings underscore the existence of sea anemone toxins with diverse mechanisms of action beyond those previously documented.

This study emphasizes the phytochemical study of some locally available botanicals against maize weevils. Nine plant parts were collected from six plant species. The test plant powder (200 g) was suspended sequentially in 600 ml of petroleum ether, chloroform, acetone, methanol, and distilled water for 72 h with frequent agitation. Different concentrations of the crude extracts were applied to maize seeds at rates of 10 ml, 15 ml and 20 ml per 100 g. All treatments with different extracts at different rates of application showed significant differences (p < 0.05) in the cumulative mean percentage mortality of the maize weevil. The seed extract of Maesa lanceolata and Croton macrostachyus and the leaf extract of Clausena anisata showed cumulative percent mortality ranged 95.32-98.02% in 28 days after treatment application. There was no significant difference (p > 0.05) among all treatments for the prevention of F1 progeny emergence. In all extracts, Clausena anisata showed 100% inhibition of F1 progeny emergence. All treatments significantly reduced seed weight loss and damage. The treated maize seeds were germinated with an acceptable germination quality. In conclusion, an increased dosage of the extract resulted in significant mortality in maize weevils. The seed extracts of Maesa lanceolata and Croton macrostachyus and Clausena anisata leaf extract were observed to be the most promising botanical in protecting stored maize against maize weevil.

UNASSIGNED: The roots of Verbascum sinaiticum have been used traditionally for the management of wound in different regions of Ethiopia. Despite the presence of several claims and in vitro studies regarding its role in wound healing, no scientific studies have been conducted so far. Therefore, this study aims to scientifically evaluate the wound healing activities of the crude extract and solvent fractions of the roots of Verbascum sinaiticum in Swiss albino mice.
UNASSIGNED: The dried root powder of Verbascum sinaiticum was extracted using 80% methanol by maceration technique. This was then fractionated with chloroform, ethyl acetate, and water. These extracts were formulated as ointment at 5% and 10% concentration by using simple base. Acute dermal toxicity was performed on mice. The wound healing potential was evaluated using excision, incision, and burn wound models.
UNASSIGNED: In excision wound, 10% and 5% of crude extract ointment provided a significant (P<0.001) percentage of contraction starting from day 4 and day 6 onwards respectively. Moreover, the rate of epithelialization was significantly (P<0.001) improved in 10% crude extract. In burn wound, 10% and 5% crude extract showed significant (P<0.001) wound contraction starting from day 4 and 8 onwards respectively. In both excision and burn wounds, a moderate concentration of fibroblast proliferation and collagen deposition was observed on the 10% crude extract. The 5% and 10% aqueous and ethyl acetate fractions produced a significant (P<0.001) percentage of wound contraction and shortening of epithelialization at different time points compared to simple ointment.
UNASSIGNED: The results of this study demonstrated that the 80% methanolic crude extract, aqueous and ethyl acetate fractions of Verbascum sinaiticum root have wound healing potential which assimilates its traditional use.

Soybeans rank among the top five globally produced crops. Black soybeans contain anthocyanins in their seed coat, offering strong antioxidant and anti-inflammatory benefits. This study explores the protective effects of black soybean seed coat (BSSC) against acute liver injury (ALI) in mice. Mice pretreated with BSSC crude extract showed reduced liver damage, inflammation, and apoptosis. High doses (300 mg/kg) of the extract decreased levels of proinflammatory cytokines (IL-6, IFN-γ) and increased levels of anti-inflammatory ones (IL-4, IL-10), alongside mitigating liver pathological damage. Additionally, it influenced the Nrf2/HO-1 pathway and reduced levels of apoptosis-related proteins. In vitro, the compounds delphinidin-3-O-glucoside (D3G) and cyanidin-3-O-glucoside (C3G) in BSSC were found to modulate cytokine levels, suggesting their role in ALI protection. The study concludes that BSSC extract, particularly due to D3G and C3G, effectively protects against LPS-induced ALI in mice by inhibiting inflammation, oxidative stress, and apoptosis.

BACKGROUND:  An assessment of Suaeda monoica extract\'s antimicrobial and antioxidant properties was undertaken in light of its possible application as an oral care product. The maintenance of optimal dental health is just as important as overall wellness. Food particles become trapped in the mouth cavity, making it easy for oral bacteria to infect.
OBJECTIVE:  The study sought to ascertain the antibacterial and antioxidant properties of salt marsh Suaeda monoica extract.
METHODS:  Leaves of Suaeda monoica, collected, dried and powdered, were dissolved in 70% methanol and the extract of 25-100 μg/ml was analyzed for antioxidant activity through total antioxidant assay, 2,2-diphenyl-1-picrylhydrazyl (DPPH) assay, and total reducing power. Suaeda monoica antibacterial activity was also performed and the minimum inhibitory concentration was determined for 75 μg/ml, 100μg/ml, and 150 μg/ml concentrations and tetracycline in 10mcg/disc as a control against three different oral pathogens: Staphylococcus mutans, Streptococcus aureus, and Klebsiella spp.
RESULTS:  At varying concentrations of 75 mg/ml to 150 mg/ml, Suaeda monoica extracts are efficacious with varying concentrations against the investigated bacterial strains. In the present study, in the DPPH assay, total reducing power, and total antioxidant activity assay, there was an increase in inhibitory percentage as the concentration increased from 25-100 µg/ml, showing maximum inhibition at 100 µg/ml concentration.
CONCLUSIONS:  The results of the investigation show that Suaeda monoica has significant antibacterial and antioxidant activity in a concentration-dependent manner and can be potentially used as an oral care agent after it is assessed for clinical use.

UNASSIGNED: This study evaluates the acute and sub-acute toxicity of 80% methanolic extracts of the leaves of Justicia schimperiana in Wistar albino rat models.
UNASSIGNED: Dried powdered leaves of Justicia schimperiana were macerated in 80% methanol. The experiment was conducted in accordance with the Organization for Economic Co-operation and Development guideline 423 for acute and 407 for sub-acute toxicity testing. A single dose of 5000 mg/kg extract was orally administered to three female rats for the acute toxicity study. The plant extract was administered orally for 28 days in daily dosages of 250, 500, and 1000 mg/kg for the sub-acute study. Animals in a control group were given distilled water. A total of 40 rats (5 rats/group/sex) were used for the sub-acute toxicity testing. Daily food intake and weekly body weight measurements were done. The rats were sacrificed at the end of the 28-day treatment period for hematological, biochemical, and histopathological tests. One-way analysis of variance and Kruskal-Wallis tests were employed for the analysis.
UNASSIGNED: The single-dose oral administration of the plant resulted in no deaths or serious morbidity. The median lethal dose was >5000 mg/kg. The 28-day oral treatment of the plant extract had no significant effect on general behavior, food intake, organ weight, biochemical parameters, or the majority of the hematological markers, with the exception of the decrease in hemoglobin and hematocrit in the 1000 mg/kg extract-treated groups compared to the controls. Both sexes experienced significant weight increases at all dosage levels. With the exception of minor alterations in a few of the organs, no significant histological change was identified.
UNASSIGNED: It is concluded that the single-dose and repeated-dose 28-day oral administration of the methanolic leaf extract of Justicia schimperiana is relatively safe.

Aphis craccivora (Hemiptera: Aphididae) is an important pest affecting various crops worldwide. However, only few studies have been conducted on the infection of A. craccivora by Lecanicillium and related insecticidal mechanisms. We investigated the infection process of A. craccivora by Lecanicillium araneicola HK-1 using fluorescence microscopy and scanning electron microscopy (SEM), and our results indicated that the conidia of strain HK-1 easily attached to the feet and dorsum of A. craccivora. The activities of chitinase and extracellular protease were induced in the aphid after treatment with HK-1. A bioassay on A. craccivora showed that the median lethal concentration (LC50) of the fungus crude extract was 24.00 mg mL-1 for 24 h of treatment. Additionally, the results showed that the crude extract disrupted the enzyme system of A. craccivora, inducing the inhibition of carboxylesterase (CarE) and the induction of glutathione S-transferase (GST) and acetylcholinesterase (AChE). Combining these results with those of a gas chromatography-mass spectrometry (GC-MS) analysis, it is suggested that p-cymene, hymecromone, 9,12-octadecadienoic acid (Z, Z) methyl ester, and 9,12-octadecadienoic acid (Z, Z) may be connected to the insecticidal effects we observed. This study provides a theoretical basis for the use of L. araneicola HK-1 as a potential biological control agent.

Pharmacology experts place a high priority on therapeutic plants because the majority of pharmaceutical firms rely on medicinal plants as raw ingredients. Therefore, the potential bioactive components using gas chromatography-mass spectrometry analysis and antioxidant effects using DPPH free radical scavenging activity of various crude fractions of Xanthium spinosum were assessed. Gas chromatography-mass spectrometry analysis showed the presence of various bioactive compounds including benzenedicarboxylic acid (18.60%), 8-octadecenoic acid (4.86%), 11-octadecenoic acid and 10-octadecenoic acid in the crude methanolic extract, 1,2-benzenedicarboxylic acid, diisooctyl ester (14.42%), 1,2-benzenedicarboxylic acid, mono (2-ethylhexyl) ester (14.42%), 6-octadecenoic acid, methyl ester (7.56%), 8-octadecenoic acid, methyl ester (7.56%), 10-octadecenoic acid, methyl ester (7.56%) and hexadecanoic acid, methyl ester (6.55%) in the n-hexane extract, ethanal, 2-methyl-2-[4-(1-methylethyl)phenyl]-(3.02%), (+)-3-carene, 4-isopropenyl-(3.02%), 7H-indeno[5,6-b] furan-7-one, 4,4a,5,6,7a,8-hexahydro- (3.02%) and 2-[5-(2,2-dimethyl-6-methylene-cyclohexyl)-3-methyl-pent-2-enyl]-[1,4] benzoquinone (2.79%) in the chloroform extract and 1,2-benzenedicarboxylic acid, mono (2-ethylhexyl) ester (33.005%), 1,2-benzenedicarboxylic acid, diisooctyl ester (33.005%) and bis(2-ethylhexyl) phthalate (33.005%) in the ethyl acetate extract. Significant DPPH radical scavenging activity was exhibited by the chloroform fraction (43.37-88.65%) at all doses followed by the crude methanolic extract (36.02-83.75%) at all doses. In conclusion, different crude fractions of X. spinosum can be considered a rich source of pharmacologically active components that can be scoped for isolation and may be subjected to in-depth pharmacological study.

Insecticide resistance is a threat to vector control worldwide. In the Philippines, dengue burden remains significant, thus prioritizing the need to develop eco-friendly control strategies and tools against mosquito vectors. Various Allium species have been found to possess larvicidal activity against dengue-carrying mosquitoes. In this study, the larvicidal activity of the crude extract of Allium ampeloprasum L. (Asparagales: Amaryllidaceae) was studied in concentrations ranging from 1 to 10,000 mg/L against the third (L3) and fourth (L4) larval instars of Aedes aegypti L. Larval mortality at 48 h were subjected to probit analysis and Kruskal-Wallis H test to estimate lethal concentrations and to determine significant means among the groups, respectively. Results show that the crude extract of A. ampeloprasum L. demonstrated larvicidal activity against the L3 and L4 Ae. aegypti L. Concentrations corresponding to 50% mortality (Lethal Concentration 50 [LC50]) among L3 and L4 larvae were estimated at 2,829.16 and 13,014.06 mg/L, respectively. Moreover, 90% mortality (LC90) in the L3 and L4 larvae were estimated at 9,749.75 and 57,836.58 mg/L, respectively. Only 1,000 and 10,000 mg/L for L3, and the 10,000 mg/L for L4, had comparable larvicidal action to the commercial larvicide used as a positive control. The results support the presence of bioactive compounds with larvicidal properties, thus suggesting A. ampeloprasum L. as a potential source of active ingredients for the development of a plant-based larvicide.

UNASSIGNED: Because of the scarcity, high cost, and severe side effects of current medications, it is necessary to discover novel, safe, and affordable anti-diabetic drugs. The current study was conducted to evaluate the antidiabetic activities of Verbascum sinaiticum Benth leaves in mice.
UNASSIGNED: Leaf coarse powder was extracted with 80% methanol and then fractionated with n-hexane, ethyl acetate, and distilled water. The glucose-lowering effects of V. sinaiticum at 100, 200, and 400mg/kg were then studied. Glibenclamide was used as a positive control at a dose of 5 mg/kg. For oral glucose tolerance tests and hypoglycemia tests, Tween 2% was used as a negative control, while citrate buffer was used as a negative control for antihyperglycemic investigations. The results from the study were evaluated using one-way ANOVA, and then Tukey\'s post hoc multiple comparison test was performed.
UNASSIGNED: Blood glucose levels were significantly reduced by the V. sinaiticum 80% methanol extract at 400 mg/kg (p<0.05). The blood glucose levels were significantly lowered by the aqueous residue at 400 mg/kg (p<0.05) and the ethyl acetate fractions at 200 mg/kg (p<0.01) and 400 mg/kg (p<0.001); however, none of the fraction extracts resulted in hypoglycemic shock in healthy mice. Higher glucose tolerance was seen in orally glucose-loaded mice after exposure to 80% methanol extracts at 200 and 400 mg/kg (p<0.05), the aqueous residual fraction at 200 mg/kg (p<0.01), and the ethyl acetate fraction at 200 and 400 mg/kg (p<0.05). The ethyl acetate fraction at 200 and 400 mg/kg (p<0.01), the 80% methanol extract at 400 mg/kg (p<0.05) and the aqueous residue at 400 mg/kg (p 0.01) significantly lowered blood glucose levels in streptozotocin-induced diabetic mice.
UNASSIGNED: The results of this study revealed that the 80% methanol extract and solvent fractions of V. sinaiticum Benth leaves are endowed with antidiabetic activity.
