Boric acid is widely used as an insecticide, acaricide, herbicide, and fungicide and also during various industrial processings. Hence, numerous populations are subjects to this toxic compound. Its action on animals is still not fully known and understood. We examined the effect of boric acid on larvae of greater wax moth (Galleria mellonella). The chemical appeared to be toxic for larvae, usually in a concentration-dependent manner. Exposed groups revealed increased lipid peroxidation and altered activity of catalase, superoxide dismutase, glutathione S-transferase, and glutathione peroxidase. We also observed changes of ultrastructure, which were in tune with biochemical assays. We suggest that boric acid has a broad mode of action, which may affect exposed larvae, and even if sublethal, they may lead to disturbances within exposed populations.

Tonoplast intrinsic proteins (TIPs) are the channel-forming proteins predominantly found in the tonoplast of plant cells. Despite the identification of TIPs in numerous plant species, very less is known about the precise role of different TIP subgroups. In the present study, two genes belonging to the TIP3 subgroup were studied to understand tissue-specific role and solute transport activity.

Therapeutic potential of boric acid as a local drug delivery agent in periodontitis: a comprehensive systematic review and meta-analysis.

BMC Oral Health

January 2025

Oral Medicine, Periodontology, Diagnosis and Oral Radiology Department, Faculty of Dentistry, Mansoura University, Mansoura City, 33516, Egypt.

Objective: This systematic review and meta-analysis aim to evaluate the therapeutic potential of boric acid as a local drug delivery agent in the treatment of periodontitis.

Methods: Following PRISMA guidelines, we registered a comprehensive protocol with PROSPERO. By employing PICOS criteria, we evaluated randomized controlled trials assessing the effects of subgingival boric acid application alongside non-surgical periodontal therapy in treatment of periodontitis.

Limited advancements in managing malignant brain tumors have resulted in poor prognoses for glioblastoma (GBM) patients. Standard treatment involves surgery, radiotherapy, and chemotherapy, which lack specificity and damage healthy brain tissue. Boron-containing compounds, such as boric acid (BA), exhibit diverse biological effects, including anticancer properties.

This study aimed to determine the protective role of boric acid in a pregnant rat model of high fructose corn syrup consumption. Consumption of high fructose corn syrup has been associated with adverse health outcomes in humans and animals. Twenty-eight healthy female Wistar albino rats (250-300 g weight and 16-24 weeks old) were randomly distributed into four equal groups (n = 7): Control, Boric acid (BA), High Fructose Corn Syrup (HFCS), HFCS + BA.

Fluorescent distinguishing flavonoid glycosides against aglycones based on the selective recognization of boric acid-functional Eu(III)-organic framework.

Talanta

January 2025

State Key Laboratory of Electroanalytical Chemistry, Changchun Institute of Applied Chemistry, Chinese Academy of Sciences, Changchun, Jilin, 130022, China. Electronic address:

Flavonoid glycosides are formed by dehydration condensation of aglycones and sugar molecules. Therefore, discrimination of flavonoid glycosides from their corresponding aglycones is a challenging task because they contain the same aglycone part in their molecular structures. Herein, boric acid-functional Eu(III)-organic framework (BA-Eu-MOF) was applied to discriminate flavonoid glycosides including baicalin (Bai), wogonoside (Wog), rutin (Rut), puerarin (Pue), quercitrin (Que) and astragalin (Ast) from their corresponding aglycones for the first time.
