Abstract
Electrofluorochromic (EFC) materials and devices with controllable fluorescence properties show great application potential in advanced anticounterfeiting, information storage and display. However, the low color purity caused by the broad emission spectra and underperforming switching time of the existing EFC materials limit their application. Through biomimetic exploration and the study of reversible electrochemical responsive coordination reactions, boron-nitrogen embedded polyaromatics (B,N-PAHs) with narrow-band emission and high color purity have been successfully integrated into EFC systems, which also help to better understand the role of boron in biological activity. The EFC device achieve good performance containing quenching efficiency greater than 90% within short switching time (ton: 0.6 s, toff: 2.4 s), and nearly no performance change after 200 cycles test. Three primary color (red, green, and blue) EFC devices are successfully prepared. In addition, new phenomena are obtained and discussed in this biomimetic exploration of related boron reactions. The success and harvest of this exploration are expected to provide new ideas for optimizing properties and broadening applications of EFC materials. Moreover, it may provide ideas and reference significance for further exploring and understanding the function of boron compounds in biological systems.

Pham TAV, Nguyen MD. Subgingival 0.75% boric acid vs 1% povidone-iodine adjunctive to subgingival instrumentation in stage II and III periodontitis-A double-blind randomized clinical trial. Int J Dent Hyg 2024. [PMID: 38764161 DOI: 10.1111/idh.12819] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/26/2022] [Revised: 04/21/2024] [Accepted: 04/28/2024] [Indexed: 05/21/2024]
Abstract
PURPOSE To compare the effects of subgingival irrigation with 0.75% boric acid (BA) and 1% povidone-iodine (PVP-I) as an adjunct to scaling and root planing (SRP) on clinical and microbiologic parameters in the management of patients with periodontitis after a 12-month follow-up. METHODS Sixty systemically healthy individuals diagnosed with periodontitis were included in this double-blind randomised clinical trial. The patients were randomly allocated to treatment groups: (1) SRP plus 0.75% BA and (2) SRP plus 1% PVP-I. Whole-mouth periodontals were clinically examined, and the counts of bacteria including Aggregatibacter actinomycetemcomitans (Aa), Fusobacterium nucleatum (Fn), Porphyromonas gingivalis (Pg), Treponema denticola (Td), Tannerella forsythia (Tf), Solobacterium moorei (Sm) and Streptococcus salivarius (Ss) were tested by real-time polymerase chain reaction (PCR). RESULTS All periodontal parameters and the counts of Aa, Fn, Pg, Td, Tf, Sm and Ss in both groups showed statistically significant reductions at T3, T6 and T12 compared to T0. Whole-mouth or moderate or severe PD and CAL improvements were significantly found in the 0.75% BA group compared to the 1% PVP-I group at T3, T6 and T12. The reduction in Aa or Fn and the reduction in Ss were significantly higher in the 0.75% BA group at T6 and T12 than in the 1% PVP-I group. CONCLUSION This study shows that subgingival irrigation with 0.75% BA may be an alternative to 1% PVP-I because it promotes greater PD reductions and CAL gain, particularly up to 12 months after treatment.

Abstract
Oxidative stress and inflammation have pivotal roles in gastric ulcer development caused by alcohol consumption. Trace element boric acid taken into the human and animal body from dietary sources displays strong antioxidant and anti-inflammatory functions. However, the mechanisms underlying these actions of boric acid remain unclear, and its effectiveness in preventing gastric lesions is unknown. Therefore, the present study was undertaken to evaluate the protective effects of boric acid in alcohol-induced gastric ulcer and elucidate its potential mechanisms. Gastric ulcer was induced by 75% oral ethanol administration in rats, and the effectiveness of prophylactic boric acid treatment at 100 mg/kg concentration was assessed by histopathological examination, ELISA assay and qRT-PCR. Gross macroscopic and histopathological evaluations revealed that boric acid alleviated gastric mucosal lesions. Boric acid decreased reactive oxygen species (ROS) and malondialdehyde (MDA) concentration and the overall oxidation state of the body while improving antioxidant status. It reduced the concentration of tumor necrosis factor-alpha (TNF-α) and interleukin-6 (IL-6). The mRNA expression of JAK2 and STAT3 was decreased while the expression of AMPK was increased with boric acid pretreatment. Moreover, Sema3A and PlexinA1 levels were elevated upon boric acid pretreatment, and homocysteine levels were reduced. Our results demonstrated that boric acid protects gastric mucosa from ethanol-induced damage by regulating oxidative and inflammatory responses. In addition, our findings suggested that the gastroprotective activity of boric acid could be attributed to its regulatory function in the IL-6/JAK2/STAT3 signaling modulated by AMPK and that Sema3A/PlxnA1 axis and homocysteine are potentially involved in this process.

Sodium Pentaborate Prevents Acetaminophen-Induced Hepatorenal Injury by Suppressing Oxidative Stress, Lipid Peroxidation, Apoptosis, and Inflammatory Cytokines in Rats.

Abstract
Acetaminophen (N-acetyl-p-aminophenol, APAP, or paracetamol) is one of the drugs that may be damaging to the kidneys and liver when used in excess. In this context, it is vital to treat these side effects on the liver and kidneys with various antioxidants. Diseases have been treated using herbal and mineral remedies since ancient times. The mineral boron, found in rocks and water, is a crucial ingredient with multiple positive biological effects. The primary objective of this research is to determine whether or not boron has a protective effect against the toxicity generated by APAP in rats. Male Sprague-Dawley rats were pretreated orally with boron-source sodium pentaborate (B50 and B100 mg/kg) for 6 days by gastric gavage in order to counteract the toxicity caused by a single dose of APAP (1g/kg). APAP increased lipid peroxidation as well as serum BUN, creatinine concentrations, and serum activities of AST, ALP, and ALT by consuming GSH in liver and kidney tissues. In addition, the activity of antioxidative enzymes, including SOD, CAT, and GPx, was diminished. Inflammatory indicators such as TNF-α, IL-1β, and IL-33 were elevated in conjunction with APAP toxicity. In kidney and liver tissues, APAP dramatically increased the activity of caspase-3 and triggered apoptosis. Sodium pentaborate therapy on a short-term basis reduced biochemical levels despite these effects of APAP. This study showed that boron protects rats from the harmful effects of APAP by acting as an anti-inflammatory, antioxidant, and anti-apoptotic agent.

Abstract
The proper supplementation of boron, an essential trace element, can enhance animal immune function. We utilized the method of TMT peptide labeling in conjunction with LC-MS/MS quantitative proteomics for the purpose of examining the effects of boric acid on a rat model and analyzing proteins from the duodenum. In total, 5594 proteins were obtained from the 0, 10, and 320 mg/L boron treatment groups. Two hundred eighty-four proteins that exhibit differential expression were detected. Among the comparison, groups of 0 vs. 10 mg/L, 0 vs. 320 mg/L, and 10 vs. 320 mg/L of boron, 110, 32, and 179 proteins, respectively, demonstrated differential expression. The results revealed that these differential expression proteins (DEPs) mainly clustered into two profiles. GO annotations suggested that most of the DEPs played a role in the immune system process, in which 2'-5'-oligoadenylate synthetase-like, myxovirus resistance 1, myxovirus resistance 2, dynein cytoplasmic 1 intermediate chain 1, and coiled-coil domain containing 88B showed differential expression. The DEPs had demonstrated an augmentation in the signaling pathways, which primarily include phagosome, antigen processing, and presentation, as well as cell adhesion molecules (CAMs). Our study found that immune responses in the duodenum were enhanced by lower doses of boron and that this effect is likely mediated by changes in protein expression patterns in related signaling pathways. It offers an in-depth understanding of the underlying molecular mechanisms that lead to immune modulation in rats subjected to dietary boron treatment.

Abstract
Boron-containing compounds (BCC), particularly boronic acids and derivatives, are being increasingly tested as diagnostic and therapeutic agents. Some effects of BCC involve phenomena linked to the action of steroid or thyroid hormones; among these, are the effects on muscle mass or basal metabolism. Additionally, some toxicology reports on mammals, including humans, sound an alert concerning damage to several systems, among which are the negative effects on the induction of male infertility. Systemic and local mechanisms to explain changes in metabolism and impaired fertility were collected and presented. Then, we presented the putative pharmacodynamic and pharmacokinetic mechanisms involved and demonstrated in these events. In addition, it is proposed that there are adducts of some oxygenated BCC with cis-diols in fructose, an essential source of energy for sperm–cell motility, an uncoupling of sex hormone-binding globulin (SHBG) and its ligands, and the modulation of the DNA synthetic rate. These effects share the reactivity of boron-containing compounds on the cis-diols of key molecules. Moreover, data reporting no DNA damage after BCC administration are included. Further studies are required to support the clear role of BCC through these events to disrupt metabolism or fertility in mammals. If such phenomena are confirmed and elucidated, an advance could be useful to design strategies for avoiding BCC toxicity after BCC administration, and possibly for designing metabolism regulators and contraceptive drugs, among other purposes. Boronic derivatives and carboranes have been proposed and studied in this field.

Abstract
As an essential trace element, appropriate boron supplementation can promote immune function of animals. To illustrate the effects of boron in a rat model, RNA-Seq was conducted for the RNA from duodenum after treatment with different concentration of boron in which boron was given in the form of boric acid. More than 47 million reads were obtained in 0, 10, and 320 mg/L boron (0, 57.21, and 1830.66 mg/L boric acid) treatment groups that produced 58 965 402, 48 607 328, and 46 760 660 clean reads, respectively. More than 95% of the clean reads were successfully matched to the rat reference genome and assembled to generate 32 662 transcripts. A total of 624 and 391 differentially expressed candidate genes (DEGs) were found between 0 vs.10 and 0 vs. 320 mg/L boron comparison groups. We also identified transcription start site, transcription terminal site, and skipped exons as the main alternative splicing events. GO annotations revealed most of DEGs were involved in the regulation of immune activity. The DEGs were enriched in influenza A, herpes simplex infection, cytosolic DNA-sensing pathway, and antigen processing and presentation signaling pathways. The expression levels of genes enriched in these signaling pathways indicate that lower doses of boron could achieve better effects on promoting immune response in the duodenum. These effects on the immune system appear to be mediated via altering the expression patterns of genes involved in the related signaling pathways in a dose-dependent pattern. These data provide more insights into the molecular mechanisms of immune regulation in rats in response to dietary boron treatment.

The importance of nutrition in alleviating high stocking density stress in poultry. ANNALS OF ANIMAL SCIENCE 2021.

Abstract
Abstract
In recent decades, the number of birds reared per unit area has dramatically spiked to increase profitability in egg and meat production. However, nowadays, the increase in sensitivity to animal welfare and consumer demands brings along with it a raised interest in stocking density. Stocking density is defined either as the number of animals or body weight per unit area or as the area per animal. High stocking density, which is a stress factor, can be defined as an increase in the number of animals per unit area or a decrease in the area per animal. Stress caused by high stocking density negatively affects the bird’s physiology and performance as well as the quality of the product obtained. The ideal stocking density should be 9 laying hens, 35 kilogrammes for broilers, and 45 quails per square metre. Otherwise, one will observe stress indicators in birds reared in more than the recommended stocking density per unit area and, consequently, a decrease in bird growth, egg production, feed efficiency, and egg or meat quality. Apart from increasing the concentrations of amino acids such as lysine, methionine, tryptophan and arginine, minerals such as selenium and chromium, and vitamins such as C and E in the diet, the addition of additives such as probiotics, humates, phytophenol compounds, and propolis is also effective in reducing or eliminating these negative effects caused by high stocking density. As a result, regulations in the nutrition of animals are effective in reducing/preventing such negative effects, thus improving animal welfare and ensuring the maintenance of optimum yield.

Abstract
Background: Wound healing has a vital importance for the organism and various agents are used to accelerate wound healing. Although the effect of boron on wound healing is known, its mechanisms are not completely clear yet. In this study, the effect of boron in the Ephrin /Eph pathway will be evaluated. Methods: Forty adult female rats were used in the study. A full-thickness excisional wound model was created in all groups divided as Control, Fito, Boron and Plu groups. After the applications performed twice a day and lasting 7 days, skin tissues obtained and evaluated histopathological (inflammatory cell infiltration, oedema, and fibroblast proliferation density) and immunohistochemical (TNF-α, EphrinA1, EphrinB1, EphrinB2 and EphB4). Results: Inflammatory cell infiltration score was found to be higher in the Fito group compared to Boron group (p = .018). Fibroblast proliferation density was higher in Plu group than Boron group (p = .012). While TNF-α was lower in boron group than Plu (p = .027) and Fito (p = .016) groups, EphrinA1 was higher in Boron group than Plu group (p = .005). EphrinB1 expression was higher in Boron group compared to Plu (p = .015) and Fito (p = .015) groups, and the same difference was also observed in EphrinB2 (p values .000). Similarly, EphB4 immunoreactivity was higher in the Boron group compared to Plu (p = .000) and Fito (p = .002). Conclusion: One of the mechanisms of action of boron in wound healing is to increase EphrinB1, EphrinB2 and EphB4. Low TNF-α and histopathological findings indicate that boron limits extensive wound healing.

Abstract
Boron is a trace element which plays important roles in immune response. The relationship between boron and splenic lymphocyte proliferation, apoptosis, secretion of cytokines, and genes potentially related to immune response in ostrich chicks were investigated in the present study. Different concentrations of boron (0, 0.01, 0.1, 0.5, 1, 5, 10, 25, 50, and 100 mmol/L) were applied to splenic lymphocytes of African ostrich, respectively. The effect of boron on lymphocyte proliferation was checked by the CCK-8 method. Flow cytometry was used to detect the effect of boron on apoptosis. The secretion levels of IL-6 and IFN-α were determined by ELISA. Splenic lymphocyte gene expression profiles of ostrich chicks treated with boron (0, 0.1, 100 mmol/L) were studied using RNA-seq technology. The results showed that cell proliferation increased with 0.01-10 mmol/L boron, when it was 25-100 mmol/L, the cell proliferation gradually decreased as the boron concentration increased. Apoptosis ratio in ostrich splenic lymphocytes was closely related to boron concentrations. 0.01- and 0.1-mmol/L boron inhibited apoptosis in splenic lymphocytes, whereas 1, 10, 50, and 100-mmol/L boron promoted apoptosis. As the concentration of boron increased, the secretion of IL-6 gradually decreased; IFN-α was initially increased and then decreased with boron concentrations increased, reaching the maximum level with 1 mmol/L boron. In terms of the RNA-Seq data, there was no differentially expressed gene between the 0- and 0.1-mmol/L boron-treated samples; 21 differentially expressed genes were found between the 0- and 100-mmol/L boron-treated samples; 43 differentially expressed genes were found between the 0.1- and 100-mmol/L boron-treated samples. Functional analysis of the differentially expressed genes by Gene Ontology verified multiple functions associated with immune response. Pathway analysis showed that systemic lupus erythematosus, alcoholism, viral carcinogenesis, and necroptosis pathway were the major enriched pathways, and BIRC2-3, FTH1, and IL-1β genes showed differential expression in necroptosis pathway. These results demonstrated that low concentrations (0.01-0.1 mmol/L) of boron may promote the proliferation and the secretion of cytokines, inhibit cell apoptosis of ostrich splenic lymphocytes by enhancing the function of the cell membrane and the activity of intracellular catalytic enzymes, whereas high-concentration (25-100 mmol/L) boron had opposite effects on cells. The necroptosis pathway might play a pivotal role in regulating the immune response of boron-treated splenic lymphocytes in ostrich chicks.

Abstract
BACKGROUND The number of known boron-containing compounds (BCCs) is increasing due to their identification in nature and innovative synthesis procedures. Their effects on the fungal kingdom are interesting, and some of their mechanisms of action have recently been elucidated. METHODS In this review, scientific reports from relevant chemistry and biomedical databases were collected and analyzed. RESULTS It is notable that several BCC actions in fungi induce social and economic benefits for humans. In fact, boric acid was traditionally used for multiple purposes, but some novel synthetic BCCs are effective antifungal agents, particularly in their action against pathogen species, and some were recently approved for use in humans. Moreover, most reports testing BCCs in fungal species suggest a limiting effect of these compounds on some vital reactions. CONCLUSIONS New BCCs have been synthesized and tested for innovative technological and biomedical emerging applications, and new interest is developing for discovering new strategic compounds that can act as environmental or wood protectors, as well as antimycotic agents that let us improve food acquisition and control some human infections.

Abstract
Vaccination is the most effective, reliable, and economical way of preventing or reducing the effect of infectious diseases. When preparing inactive vaccines, a range of additives called adjuvants are necessary to enhance the magnitude of the immune response. Boron has a wide range of industrial and medical applications, and its positive effects on distinct functions have been described in plants, humans, and animals. However, no studies exist about the possible adjuvant activities of boron compounds in vaccines. Hence, in this study, the potential adjuvant effect of boric acid was explored and compared with common veterinary adjuvants in a mice model. Staphylococcus aureus (S. aureus) used as vaccine antigen was isolated from dairy cows with bovine mastitis. Vaccines adjuvanted with boric acid, aluminum hydroxide, Montanide ISA 50 and ISA 206, and Montanide + boric acid combinations were prepared. The efficacy of vaccines was evaluated according to local reactions at the injection site, C-reactive protein, total Ig G, total Ig M, and anti-S. aureus antibody levels in mice. Boric acid reduced local inflammatory reactions induced by the Montanide adjuvants. Moreover, mice vaccinated with boric acid-adjuvanted vaccine had higher levels of anti-S. aureus antibody than those in the controls (P < 0.05) and were similar to the levels found in mice sensitized with aluminum hydroxide. Total Ig G and Ig M results were, however, unsuitable for the assessment of adjuvant activity for this study. In conclusion, this study revealed that boric acid has an adjuvant potential in inactive bacterin vaccines, but further target animal studies are needed.

Determining the Importance of Macro and Trace Dietary Minerals on Growth and Nutrient Retention in Juvenile Penaeus monodon. Animals (Basel) 2020; 10:ani10112086. [PMID: 33182790 PMCID: PMC7697541 DOI: 10.3390/ani10112086] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/25/2020] [Revised: 11/05/2020] [Accepted: 11/05/2020] [Indexed: 11/28/2022] Open
Abstract
Simple Summary Knowledge of mineral requirements enables diets to be better formulated. Mineral requirements of black tiger prawns (Penaeus monodon) are not well known compared with other cultured prawn species. To close this knowledge gap, the importance of providing additional sources of twelve minerals in prawn diets were assessed. These minerals are known to be required for optimal growth in other animals and included boron, calcium:phosphorus at 1:1 ratio, cobalt, copper, magnesium, manganese, potassium, selenium, sodium, strontium and zinc. Inorganic forms of these minerals were incorporated into diets and fed to prawns for 6 weeks where their effect on growth performance and mineral concentrations in tissues were determined. This study was able to assess the effect of many minerals by adopting a ‘screening design’ where it was demonstrated that additions of calcium:phosphorus at 1:1 ratio, magnesium, boron, manganese, selenium and zinc to diets for black tiger prawns were important for growth, feed conversion efficiency and nutrient utilisation. Further research is needed to determine the requirement values of the important minerals identified in this study. Abstract Twelve minerals were screened to identify key dietary minerals important for Penaeus monodon growth. The minerals selected included boron, calcium plus phosphorus (assessed in tandem at a 1:1 ratio), cobalt, copper, magnesium, manganese, potassium, selenium, sodium, strontium and zinc. Twelve purified casein/gelatin-based diets were formulated and contained minerals at two levels: below expected requirements, as attributed by the basal formulation (−) and above expected requirements by adding inorganic minerals (+). The two levels were allocated to dietary treatments in juvenile prawns in accordance with the PB design. A two-level screening analysis was employed where effect of each mineral at level − or + across twelve diets were compared to identify the minerals of importance for culture performance of juvenile prawns. Calcium plus phosphorus (at a 1:1 ratio), magnesium, boron, manganese, selenium and zinc produced the greatest positive effects on weight gain, feed conversion efficiency, biomass gain and nutrient/energy retention. Particularly, boron and manganese significantly increased retention of key macronutrients and energy including gross energy, crude protein and crude lipid. Our study demonstrates the importance of several macro and trace minerals in prawn diets and the pressing need to refine their requirements for P. monodon.

Abstract
INTRODUCTION Dietary boron improves immune and antioxidant status and calcium metabolism in mammals. However, till date the effects of dietary boron supplementation on male reproduction, especially on sperm production and sperm quality in farm animals are not documented. OBJECTIVE The present study was aimed to investigate the influence of dietary boron on semen production, semen quality, immunity and molecular changes in the testis, blood and seminal plasma and to assess the interrelationship with other minerals in male goats. METHODOLOGY The study was conducted in 21 adult male goats divided into 3 groups (control, boron and selenium supplemented groups, n = 7 each). In boron group, boron was supplemented at 40 ppm and in selenium group, selenium was supplemented at 1 ppm over and above the basal level. In control group, only the basal diet was fed without supplementary boron or selenium. The feeding trial was carried out for 60 days. Selenium was taken as a positive control for the dietary boron supplementation experiment. Following feeding trials, the sperm concentration, kinematics and functional attributes, immunity and molecular level changes in the testis, biomolecular changes in the blood and seminal plasma and also interrelationship with other minerals were studied. RESULTS The average sperm concentration (million/ml) and the total sperm production (million/ejaculate) were significantly (p < 0.05) increased in boron supplemented group when compared to selenium and control groups. The boron levels in blood plasma (r = 0.65) and seminal plasma (r = 0.54) showed a positive correlation with sperm progressive motility. Blood and seminal plasma metabolic biomarker namely, aspartate aminotransferase (AST) (p < 0.01) was significantly lower in the boron and selenium supplemented group than control, while alanine aminotransferase (ALT) (p < 0.05) was significantly lower in the boron supplemented group than selenium and control group. There was a significant increase in the mRNA expression of serine proteinase inhibitor (SERPIN) and interferon γ (IFNγ) in the testis of boron supplemented than the control group. Boron supplementation up-regulated the immune-regulatory gene, interleukin 2 (IL2) and antioxidant gene, catalase (CAT) in the peripheral blood mononuclear cells (PBMC). On contrary, toll-like receptor 2 (TLR2) mRNA expression was significantly (p < 0.05) down-regulated in boron and selenium supplemented groups. CONCLUSION The study revealed that dietary boron supplementation increased the sperm output, sperm motility and enhanced the immune and antioxidant defense capacity in male goats. The improved semen quality can be attributed to enhanced expression of testicular SERPIN, a crucial protein for the regulation of spermatogenesis process.

Abstract
This study demonstrates that functionalized, highly porous polymers are promising for the adsorptive capture of boric acid, a neutral contaminant that is difficult to remove from seawater using conventional reverse osmosis membranes. Appending N-methyl-d-glucamine (NMDG) to the pore walls of high-surface-area porous aromatic frameworks (PAFs) yields the adsorbents PAF-1-NMDG and P2-NMDG in a simple two-step synthesis. The boron-selective PAFs demonstrate adsorption capacities that are up to 70% higher than those of a commercial boron-selective resin, Amberlite IRA743, and markedly faster adsorption rates, owing to their higher NMDG loadings and greater porosities relative to the resin. Remarkably, PAF-1-NMDG is able to reduce the boron concentration in synthetic seawater from 2.91 to <0.5 ppm in less than 3 min at an adsorbent loading of only 0.3 mg mL-1 . The boron adsorption rate constants of both frameworks, determined via a pseudo-second-order rate model, represent the highest values reported in the literature-in most cases orders of magnitude higher than those of other boron-selective adsorbents. The frameworks can also be readily regenerated via mild acid/base treatment and maintain constant boron adsorption capacities for at least 10 regeneration cycles. These results highlight the numerous advantages of PAFs over traditional porous polymers in water treatment applications.

Abstract
INTRODUCTION Boron-containing compounds induce effects on immune responses. Such effects are interesting to the biomedical field for the development of therapeutic tools to modulate the immune system. AREAS COVERED The scope of BCC use to modify immune responses is expanding, mainly with regard to inflammatory diseases. The information was organized to demonstrate the breadth of reported effects. BCCs act as modulators of innate and adaptive immunity, with the former including regulation of cluster differentiation and cytokine production. In addition, BCCs exert effects on inflammation induced by infectious and noninfectious agents, and there are also reports regarding their effects on mechanisms involving hypersensitivity and transplants. Finally, the authors discuss the beneficial effects of BCCs on pathologies involving various targets and mechanisms. EXPERT OPINION Some BCCs are currently used as drugs in humans. The mechanisms by which these BCCs modulate immune responses, as well as the required structure-activity relationship for each observed mechanism of action, should be clarified. The former will allow for the development of improved immunomodulatory drugs with extensive applications in medicine. Patenting trends involve claims concerning the synthesis and actions of identified molecules with a defined profile regarding cytokines, cell differentiation, proliferation, and antibody production.

Abstract
BACKGROUND Despite the historical employment of boron-containing compounds (BCCs) with medicinal purposes, the reported cases of BCC toxicity in humans during the twentieth century were driving us towards an "boron-withdrawal" period. Fortunately, the use of boric acid for specific purposes remains, and the discovery of natural BCCs with biological action attractive for therapeutic purposes as well as the introduction of some new BCCs for clinical use have reactivated the interest in studying the properties of these BCCs. METHODS We carried out a structured search of bibliographic databases for scientific peer-reviewed research literature regarding boron toxicity and linked that information to that about BCCs in drug design and development. A deductive qualitative content analysis methodology was applied to analyse the interventions and findings of the included studies using a theoretical outline. RESULTS This review recapitulates the following on a timeline: the boron uses in medicine, the data known about the toxicological profiles of some BCCs, the pharmacological properties of some BCCs that are employed in cancer and infectious disease therapies, and the known properties of BCCs recently introduced into clinical assays as well as the identification of their structure-activity relationships for toxicity and therapeutic use. Then, we discuss the use of new approaches taking advantage of some toxicological data to identify potent and efficient BCCs for prevention and therapy while limiting their toxic effects. CONCLUSION Data for boron toxicity can be strategically used for boron-containing drug design.

Bisphenol-A induced oxidative stress, inflammatory gene expression, and metabolic and histopathological changes in male Wistar albino rats: protective role of boron. Toxicol Res (Camb) 2019; 8:262-269. [PMID: 30997025 PMCID: PMC6425992 DOI: 10.1039/c8tx00312b] [Citation(s) in RCA: 44] [Impact Index Per Article: 8.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/20/2018] [Accepted: 01/07/2019] [Indexed: 11/21/2022] Open
Abstract
Bisphenol A (BPA) is one of the most produced chemicals in the world and has been widely employed in the food industry. Continuous and widespread exposure to BPA through drinking water and food leads to health concerns for humans. This study evaluated the effects of boron (B) on BPA-mediated oxidative stress in male Wistar albino rats. Rats were equally divided into 5 groups; corn oil was given orally to the control group; 25 mg kg-1 of BPA dissolved in corn oil was given orally to the second group. All other groups received the same dose of BPA and different doses of B (5, 10, and 20 mg kg-1 per day, respectively) orally for 30 days. The administration of BPA significantly decreased glutathione levels and increased malondialdehyde levels in rat tissues. Furthermore, BPA treatment reduced the catalase and superoxide dismutase activities in tissues and erythrocytes. Also, mRNA expression levels of TNF-α, IL-1β, and IL-6 in the brain, liver, and testes of rats were augmented, whereas IL-10 was decreased with BPA treatment. Besides, BPA treatment adversely altered biochemical parameters and caused damage to the cell integrity of rat tissues. However, B administration reversed BPA-induced alterations in rat tissues in a dose-dependent manner. Furthermore, B exhibited antioxidant and anti-inflammatory effects and regulated metabolic and histopathological alterations in male Wistar albino rats exposed to BPA.

Abstract
Boron (B) has many beneficial functions in biological, metabolic and physiological processes for plants and animals. It plays a vital role in maintaining animal health and preventing nutritional disorders. Boron deficiency has been correlated with low immune function and high incidence of osteoporosis which increases mortality risk. Extraordinary boron level causes cell damage and toxicity in human and different animal species. In the past few years, attention has been paid to clear the pleiotropic effects of boron including activating of immune response, antioxidant detoxification activities, affecting bone metabolism, enhancing animal performance and modulating various body systems. Furthermore, the role of boron as anti-heat stress agent has been identified in plants and suggested in animals. Liver metabolism also shows significant alterations in dairy cows in response to the dietary supplementation of boron. Likewise, adding boron to animal feed enhances bone density, wound healing and embryonic development. Additionally, boron has a potential impact on the metabolism of numerous minerals and enzymes. In view of the information about boron benefits, high or low level boron merits the concern. As well, researches are required to do more in-depth investigations on boron influences, and to adjust its requirements in different animal species.

Abstract
Boron is an essential mineral that plays an important role in several biological processes. Boron is required for growth of plants, animals, and humans. There are increasing evidences of this nutrient showing a variety of pleiotropic effects, ranging from anti-inflammatory and antioxidant effects to the modulation of different body systems. In the past few years, the trials showed disease-related polymorphisms of boron in different species, which has drawn attention of scientists to the significance of boron to health. Low boron profile has been related with poor immune function, increased risk of mortality, osteoporosis, and cognitive deterioration. High boron status revealed injury to cell and toxicity in different animals and humans. Some studies have shown some benefits of higher boron status, but findings have been generally mixed, which perhaps accentuates the fact that dietary intake will benefit only if supplemental amount is appropriate. The health benefits of boron are numerous in animals and humans; for instance, it affects the growth at safe intake. Central nervous system shows improvement and immune organs exhibit enhanced immunity with boron supplementation. Hepatic metabolism also shows positive changes in response to dietary boron intake. Furthermore, animals and human fed diets supplemented with boron reveal improved bone density and other benefits including embryonic development, wound healing, and cancer therapy. It has also been reported that boron affects the metabolism of several enzymes and minerals. In the background of these health benefits, low or high boron status is giving cause for concern. Additionally, researches are needed to further elucidate the mechanisms of boron effects, and determine the requirements in different species.

Abstract
Three-dimensionally ordered macroporous cross-linked poly(glycidyl methacrylate) (3DOM) was constructed by water-soluble colloidal crystal templates and further functionalized with N-methyl-d-glucamine (NMDG) to prepare superhydrophilic adsorbents for boron removal from natural seawater. 3DOM adsorbents possess features of interconnected macropore structure, ultrathin pore wall, and superhydrophilicity, making efficient adsorption possible. The effect of cross-linking degree on the adsorption capacity toward boron was investigated. The NMDG-modified 3DOM adsorbent with rich vicinal diol functional groups showed superhydrophilicity and outstanding performance of adsorption. Significantly, its adsorption effect in boron removal from natural seawater indicated that the concentration of boron in natural seawater could decline to 0.16 from 4.24 mg·L-1 when the adsorbent dosage was 1 g·L-1, whereas the boron rejection reached 96.2%. After 10 regeneration-adsorption cycles, the adsorption capacity of 3DOM adsorbent remained over 85% of the initial value and the ordered structure was hardly changed. Additionally, 3DOM adsorbent could be directly and quickly separated from the seawater by a filter mesh of 16 mesh number. Research shows that the 3DOM adsorbent exhibits an adsorption performance for practical applications in boron removal from natural seawater.

Changes in the bioelement content of summer and winter western honeybees (Apis mellifera) induced by Nosema ceranae infection. PLoS One 2018; 13:e0200410. [PMID: 30044811 PMCID: PMC6060561 DOI: 10.1371/journal.pone.0200410] [Citation(s) in RCA: 16] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/02/2018] [Accepted: 06/26/2018] [Indexed: 12/13/2022] Open
Abstract
Proper bioelement content is crucial for the health and wellness of all
organisms, including honeybees. However, the situation is more complicated in
these important pollinators due to the fact that they change their physiology
during winter in order to survive the relatively harsh climatic conditions.
Additionally, honeybees are susceptible to many diseases such as
nosemosis, which during winter can depopulate an entire
colony. Here we show that summer bees have a markedly higher content of
important bioelements such as: Al, Cu, P, V, (physiologically essential); Ca, K,
Mg, (electrolytic); Cr, Se, Zn, (enzymatic); As, Hg, (toxic). In contrast, a
markedly higher content of: Fe (physiologically essential); Mn, Ni, (enzymatic);
Cd (exclusively toxic) were present in winter bees. Importantly,
N. ceranae infection resulted in an
increased honeybee bioelement content of: S, Sr (physiologically essential) and
Pb (exclusively toxic), whereas the Nosema-free worker-bees had
higher amounts of B and Si (physiologically essential). We propose that the
shortages of Fe, Mn, Ni, and Na observed in Nosema-infected
bees, could be the reason for the higher mortality of
Nosema-infected bees throughout overwintering. In addition, a
shortage of bioelements such as B and Si may be a reason for accelerated aging
in foragers that is observed following N.
ceranae infection. Therefore, in winter, bioelement content
was more strongly affected by N. ceranae
infection than during summer. We found a strong correlation between the
bioelement content of bees and seasons (summer or winter) and also with
Nosema infection. We conclude that the balance of
bioelements in the honeybee is altered by both seasonal affects and by
Nosema infection.

Evaluation of a Solid Dispersion of Curcumin With Polyvinylpyrrolidone and Boric Acid Against Salmonella Enteritidis Infection and Intestinal Permeability in Broiler Chickens: A Pilot Study. Front Microbiol 2018; 9:1289. [PMID: 29973919 PMCID: PMC6020768 DOI: 10.3389/fmicb.2018.01289] [Citation(s) in RCA: 24] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/03/2018] [Accepted: 05/28/2018] [Indexed: 12/26/2022] Open
Abstract
In the present study, in vitro assays were conducted to evaluate the solubility of curcumin (CUR) alone or with polyvinylpyrrolidone (PVP) at different pH, as well as its permeability in Caco-2 cells. Results confirmed that the solid dispersion of CUR with PVP (CUR/PVP) at a 1:9 ratio, significantly increased (P < 0.05) solubility and permeability compared to CUR alone. Then, the antimicrobial activity of CUR/PVP, boric acid (BA), and a combination of 0.5% CUR/PVP and 0.5% BA (CUR/PVP-BA) against Salmonella Enteritidis (SE) was determined using an in vitro digestion model that simulates crop, proventriculus, and intestine. The results revealed that in the proventriculus and intestinal compartments significant reductions of SE were observed in all the experimental treatments, but 1% BA eliminated SE in the intestinal compartment and CUR/PVP-BA showed a synergistic effect on antimicrobial activity against SE. To complement these findings, two independent in vivo trials were conducted to determine the effect of 0.1% CUR/PVP; 0.1% BA; or the combination of 0.05% CUR/PVP (1:9 ratio) and 0.05% BA (CUR/PVP-BA) on the antimicrobial activity against SE, intestinal permeability and inflammatory responses in broiler chickens. BA at 0.1% had no significant in vivo effects against SE. However, the combination of 0.05% BA and 0.05% CUR/PVP and 0.05% BA was sufficient to reduce crop and intestinal SE colonization in broiler chickens in two independent trials, confirming the synergic effect between them. A similar antimicrobial impact against SE intestinal colonization was observed in chickens treated with 0.1% CUR/PVP at a 1:9 ratio, which could be due to the increase in solubility of CUR by PVP. Furthermore, 0.1% CUR/PVP reduced the intestinal permeability of FITC-d and total intestinal IgA, as well as increase the activity of SOD when compared to control, while, CUR/PVP-BA only decreased SOD activity. Further studies to confirm and expand the in vivo results obtained in this pilot study, adding intestinal microbial commensal groups and more inflammatory biomarkers to get a complete description of the effects of BA and CUR deserves further investigation.

Abstract
Increased synthesis of heat shock protein 70 (Hsp70) occurs in prokaryotes and eukaryotes in response to physiological, environmental, and chemical exposures, thus allowing the cell survival from fatal conditions. Hsp70 cytoprotective properties may be clarified by its anti-apoptotic function. Boron has been reported to play an essential role in various organ developments and metabolisms. However, it is not known if boron is also able to modulate the Hsp70. In the present study, the actions of boron on ostrich spleen and expression level of Hsp70 were investigated. Thirty healthy ostrich chicks were randomly assigned to six groups: groups I, II, III, IV, V, and VI and fed the basal diet spiked with 0-, 40-, 80-, 160-, 320-, and 640-mg boric acid (BA)/L, respectively, in drinking water. The histomorphological examination in the spleen was done by hematoxylin and eosin (HE) staining. The expression level of Hsp70 was analyzed by immunohistochemistry (IHC) and western blotting, and mRNA expression of Hsp70 was investigated by quantitative real-time PCR (qPCR). In order to investigate apoptosis, TUNEL assay reaction in all treatment groups was analyzed. Our results showed that the histological structure of spleen up to 160 mg/L BA supplementation groups well developed. The Hsp70 expression level first induced at low-dose groups (up to group IV) and then inhibited dramatically in high-dose groups (V and VI) while comparing with the group I (0 mg BA). The TUNEL assay reaction revealed that the cell apoptosis amount was decreased in group IV, but in group V and especially in group VI, it was significantly increased (P < 0.01). Taken altogether, proper dietary boron treatment might stimulate ostrich chick spleen development by promoting the Hsp70 expression level and inhibiting apoptosis, while a high amount of boron supplementation would impair the ostrich spleen structure by inhibiting Hsp70 expression level and promoting cell apoptosis.

Abstract
AIMS To compare the conventional plating method vs a fluorometric method using PrestoBlue® as a dye by determining the antimicrobial activity of two organic acids and curcumin (CUR) against Salmonella Enteritidis in an avian in vitro digestion model that simulates the crop, proventriculus and intestine. METHODS AND RESULTS A concentration of 108 CFU per ml of S. Enteritidis was exposed to groups with different rates of ascorbic acid (AA), boric acid (BA) and CUR. Significant differences were observed when the means of the treatments were compared with the controls in the compartments that simulate the crop and intestine (P < 0·05). Ascorbic acid alone and high rates of AA in the mixtures were the most efficient treatments in the crop compartment. However, in the intestinal compartment BA alone and at different rates in the mixture BA-CUR (1 : 1) were the best treatments to decrease the concentration of S. Enteritidis. CONCLUSIONS The results of this study suggest that there could be an antagonistic bactericidal effect between AA and CUR and AA and BA as well as a synergistic bactericidal effect between BA and CUR. SIGNIFICANCE AND IMPACT OF THE STUDY These findings may contribute to the development of a formulation with microencapsulated compounds to liberate them in different compartments to combat S. Enteritidis infections in broiler chickens.

Abstract
Boron is an essential element for plants and probably essential for human and animal health. Boron has a broad range of physiological effects on biological systems at low concentrations, whereas it is toxic to at high concentrations. Eventhough there are many studies on boron's biological effects and toxicity, more information is needed to understand the mechanisms of its action. The aim of the current work is to review boron's function, transport and toxicity in different biological systems.

Abstract
This study demonstrated the mechanisms of boron effects in a rat model and provided a scientific basis for the rational of boron use. These findings were achieved by investigating the effects of boron (10, 20, 40, 80, 160, 320, and 640 mg/L in drinking water or 1.5, 3, 6, 12, 24, 48, and 96 mg/kg BW) on rat serum immunoglobulins (IgGs), splenic cytokines, lymphocyte subsets, as well as on lymphocyte proliferation and apoptosis. Addition of 20 (3) and 40 (6) mg/L (mg/kg BW) of boron to drinking water significantly increased rat serum IgG concentrations, splenic IFN-γ and IL-4 expression as well as the number of splenic CD3+, CD4+ and proliferating cell nuclear antigen (PCNA)+ cells. Supplementation of drinking water with 40 mg/L (6 mg/kg BW) boron also markedly increased splenic IL-2 expression and the CD4+/CD8+ cell ratio and reduced splenic CD8+ cell number. Supplementation with 80 mg/L (12 mg/kg BW) boron significantly increased CD3+ and PCNA+ cell numbers (P < 0.05) and decreased the IL-10 expression in the spleen. Addition of 320 (48) and 640 (96) mg/L (mg/kg BW) boron markedly reduced the serum IgG concentrations; splenic IL-2 and IL-10 expression; the number of CD3+, CD4+ and PCNA+ cells; and increased the number of splenic CD8+ and caspase-3+ cells and promoted caspase-3 expression in CD3+ cells. In conclusion, these findings suggest that the supplementation of rat drinking water with 20(3) and 40(6) mg/L (mg/kg BW) boron can markedly enhance humoral and cellular immune functions, while boron concentrations above 320 mg/L (48 mg/kg BW) can have an inhibitory effect or even toxicity on immune functions. These results exhibit a U-shaped response characteristic of low and high doses of boron supplementation on immune function and imply that proper boron supplementation in food for humans and animals could be used as an immunity regulator.

Abstract
Fruits, nuts, legumes, and vegetables are rich sources of boron (B), an essential plant nutrient with chemopreventive properties. Blood boric acid (BA) levels reflect recent B intake, and men at the US mean intake have a reported non-fasting level of 10 μM. Treatment of DU-145 prostate cancer cells with physiological concentrations of BA inhibits cell proliferation without causing apoptosis and activates eukaryotic initiation factor 2 (eIF2α). EIF2α induces cell differentiation and protects cells by redirecting gene expression to manage endoplasmic reticulum stress. Our objective was to determine the temporal expression of endoplasmic reticulum (ER) stress-activated genes in DU-145 prostate cells treated with 10 μM BA. Immunoblots showed post-treatment increases in eIF2α protein at 30 min and ATF4 and ATF6 proteins at 1 h and 30 min, respectively. The increase in ATF4 was accompanied by an increase in the expression of its downstream genes growth arrest and DNA damage-induced protein 34 (GADD34) and homocysteine-induced ER protein (Herp), but a decrease in GADD153/CCAAT/enhancer-binding protein homologous protein (CHOP), a pro-apoptotic gene. The increase in ATF6 was accompanied by an increase in expression of its downstream genes GRP78/BiP, calreticulin, Grp94, and EDEM. BA did not activate IRE1 or induce cleavage of XBP1 mRNA, a target of IRE1. Low boron status has been associated with increased cancer risk, low bone mineralization, and retinal degeneration. ATF4 and BiP/GRP78 function in osteogenesis and bone remodeling, calreticulin is required for tumor suppressor p53 function and mineralization of teeth, and BiP/GRP78 and EDEM prevent the aggregation of misfolded opsins which leads to retinal degeneration. The identification of BA-activated genes that regulate its phenotypic effects provides a molecular underpinning for boron nutrition and biology.

Abstract
AbstractBoric acid, H3BO3, is a weak acid and at physiological pH is in the form of an uncharged small molecule. Behaving as a Lewis acid, it forms complexes with amino- and hydroxy acids, carbohydrates, nucleotides and vitamins through electron donor-acceptor interactions. These interactions are believed to be beneficial for human health. Synthetic bis-chelate complexes of boric acid with organic biomolecules are therefore considered for nutritional and/or pharmaceutical applications. The use of boric acid for BNCT has gained attention due to the short biological half-life, solubility, plasma circulation and the non-selective soft tissue accumulation properties of this simple molecule. Complexation of boric acid with sugars is of particular importance in understanding the role of boron as a carrier for nucleotides and carbohydrates. A potential and catalytic role of boric acid in peptide and nucleic acid synthesis and in the stabilization of sugar molecules by acting as a complexing agent have been demonstrated. Its possible role as a phosphorylation chaperone in a prebiotic world has been recently suggested. This contribution reviews the highlights in the physiologic, therapeutic and prebiotic significance of boric acid in the last decade.

Abstract
After a disruption of skin integrity, the body produces an immediate response followed by a functional and comparable regeneration period, referred to as wound healing. Although normal wounds do not need much attention during the healing period, chronic (non-healing) wounds are the major challenge of current dermatological applications. Therefore, developing new, safe, and effective wound healing drugs has always been an attractive area of international research. In the current study, sodium pentaborate pentahydrate (NaB), pluronics (Plu; F68 and F127), and their combinations were investigated for their wound healing activities, using in vitro and in vivo approaches. The results revealed that NaB significantly increased migration capacity and superoxide dismutase activity in primary human fibroblasts. Combinations of optimized concentrations for pluronic block co-polymers further increased cell migration, and the messenger RNA (mRNA) expression levels of important growth factor and cytokines (vascular endothelial growth factor (VEGF), transforming growth factor beta (TGF-β), and tumor necrosis factor alpha (TNF-α)). NaB containing hydrogel co-formulated with pluronics was also investigated for their wound healing activities using a full thickness wound model in rats. Macroscopic and histopathological analysis confirmed that wounds in combination gel-treated groups healed faster than those of control groups. NaB/Plu gel application was found to increase wound contraction and collagen deposition in the wound area. Therefore, our results suggest that NaB, and its pluronics combination, could be used in dermatological clinics and be a future solution for chronic wounds. However, further studies should be conducted to explore its exact action of mechanism and effects of this formulation on chronic wounds.

Abstract
In vitro, animal, and human experiments have shown that boron is a bioactive element in nutritional amounts that beneficially affects bone growth and central nervous system function, alleviates arthritic symptoms, facilitates hormone action and is associated with a reduced risk for some types of cancer. The diverse effects of boron suggest that it influences the formation and/or activity of substances that are involved in numerous biochemical processes. Several findings suggest that this influence is through the formation of boroesters in biomolecules containing cis-hydroxyl groups. These biomolecules include those that contain ribose (e.g., S-adenosylmethionine, diadenosine phosphates, and nicotinamide adenine dinucleotide). In addition, boron may form boroester complexes with phosphoinositides, glycoproteins, and glycolipids that affect cell membrane integrity and function. Both animal and human data indicate that an intake of less than 1.0mg/day inhibits the health benefits of boron. Dietary surveys indicate such an intake is not rare. Thus, increasing boron intake by consuming a diet rich in fruits, vegetables, nuts and pulses should be recognized as a reasonable dietary recommendation to enhance health and well-being.

Self-crosslinked oxidized alginate/gelatin hydrogel as injectable, adhesive biomimetic scaffolds for cartilage regeneration. Acta Biomater 2014; 10:3650-63.

Abstract
Biopolymeric hydrogels that mimic the properties of extracellular matrix have great potential in promoting cellular migration and proliferation for tissue regeneration. The authors reported earlier that rapidly gelling, biodegradable, injectable hydrogels can be prepared by self-crosslinking of periodate oxidized alginate and gelatin in the presence of borax, without using any toxic crosslinking agents. The present paper investigates the suitability of this hydrogel as a minimally invasive injectable, cell-attractive and adhesive scaffold for cartilage tissue engineering for the treatment of osteoarthritis. Time and frequency sweep rheology analysis confirmed gel formation within 20s. The hydrogel integrated well with the cartilage tissue, with a burst pressure of 70±3mmHg, indicating its adhesive nature. Hydrogel induced negligible inflammatory and oxidative stress responses, a prerequisite for the management and treatment of osteoarthritis. Scanning electron microscopy images of primary murine chondrocytes encapsulated within the matrix revealed attachment of cells onto the hydrogel matrix. Chondrocytes demonstrated viability, proliferation and migration within the matrix, while maintaining their phenotype, as seen by expression of collagen type II and aggrecan, and functionality, as seen by enhanced glycosoaminoglycan (GAG) deposition with time. DNA content and GAG deposition of chondrocytes within the matrix can be tuned by incorporation of bioactive signaling molecules such as dexamethasone, chondroitin sulphate, platelet derived growth factor (PDGF-BB) and combination of these three agents. The results suggest that self-crosslinked oxidized alginate/gelatin hydrogel may be a promising injectable, cell-attracting adhesive matrix for neo-cartilage formation in the management and treatment of osteoarthritis.

Abstract
In order to determine the relationship between boron and development of the spleen, especially in the promoting biological effects, we examined the effects of different levels of boron on weight, organ index, microstructure, and antioxidative activities of the spleen in rats. Sprague-Dawley (SD) rats were selected and treated with different concentrations of boron, and then, the organs were resected and weighed. One half of the tissue was fixed and embedded in paraffin to observe tissue structure changes. The other half of the tissue was homogenated for determining the antioxidant activities. The results showed that 40 mg/L of boron could increase weight, organ indexes, and antioxidant capacity of spleens and improve the spleen tissue structure, while the boron concentration above 80 mg/L could decrease weight, organ indexes, and antioxidant capacity of spleens and damage the spleen tissue structure. The higher the concentration, the more serious the damage was. Especially at the concentration of 640 mg/L, it could significantly inhibit the development of the spleen and even exhibit toxic effect. Hence, low boron concentration played a protective role in the development of the spleen, while high boron concentration could damage the organs and even produce toxic effect.

Abstract
Inflammation has been identified as a possible contributory factor to disruption of the normal bone remodeling process, a process essential to healthy bone mineral density. Several large population-based clinical studies have specifically shown that levels of C-reactive protein, an immune recognition protein that is a sensitive marker of inflammation, are inversely and independently associated with total bone mineral density. The evidence suggests that control of C-reactive protein levels may contribute to bone health by protecting against inflammation's disruption of the equilibrium between bone resorption and bone deposition. Calcium fructoborate, a patented complex of calcium, fructose, and boron found naturally in fresh and dried fruits, vegetables and herbs, and wine, is a sugar-borate ester. A growing body of peer-reviewed, published clinical research indicates that the calcium fructoborate significantly reduces serum levels of the C-reactive protein in humans, suggesting that this unique plant-mineral complex may contribute to bone health by controlling the inflammation associated with loss of bone mineral density.

Abstract
BACKGROUND AND OBJECTIVE The goal of the present study was to evaluate the effects of systemic boric acid on the levels of expression of RANKL and osteoprotegerin (OPG) and on histopathologic and histometric changes in a rat periodontitis model. MATERIAL AND METHODS Twenty-four Wistar rats were divided into three groups of eight animals each: nonligated (NL); ligature only (LO); and ligature plus treatment with boric acid (BA) (3 mg/kg per day for 11 d). A 4/0 silk suture was placed in a subgingival position around the mandibular right first molars; after 11 d the rats were killed, and alveolar bone loss in the first molars was histometrically determined. Periodontal tissues were examined histopathologically to assess the differences among the study groups. RANKL and OPG were detected immunohistochemically. RESULTS Alveolar bone loss was significantly higher in the LO group than in the BA and NL groups (p < 0.05). The number of inflammatory infiltrate and osteoclasts in the LO group was significantly higher than that in the NL and BA groups (p < 0.05). The numbers of osteoblasts in LO and BA groups were significantly higher compared with NL group (p < 0.05). There were significantly more RANKL-positive cells in the LO group than in the BA and NL groups (p < 0.05). There was a higher number of OPG-positive cells in the BA group than in the LO and NL groups (p < 0.05). CONCLUSION The present study shows that systemic administration of boric acid may reduce alveolar bone loss by affecting the RANKL/OPG balance in periodontal disease in rats.

Abstract
Boron is probably a prebiotic element with special importance in the so-called "sugars world". Boron is not present on Earth in its elemental form. It is found only in compounds, e.g., borax, boric acid, kernite, ulexite, colemanite and other borates. Volcanic spring waters sometimes contain boron-based acids (e.g., boric, metaboric, tetraboric and pyroboric acid). Borates influence the formation of ribofuranose from formaldehyde that feeds the "prebiotic metabolic cycle". The importance of boron in the living world is strongly related to its implications in the prebiotic origins of genetic material; consequently, we believe that throughout the evolution of life, the primary role of boron has been to provide thermal and chemical stability in hostile environments. The complexation of boric acid and borates with organic cis-diols remains the most probable chemical mechanism for the role of this element in the evolution of the living world. Because borates can stabilize ribose and form borate ester nucleotides, boron may have provided an essential contribution to the "pre-RNA world".

Abstract
Boron (B) is an essential element for plant growth whose deficiency causes an alteration in the expression of a wide range of genes involved in several physiological processes. However, our understanding of the signal transduction pathways that trigger the B-deficiency responses in plants is still poor. The aims of this review are (i) to summarize the genes whose transcript levels are affected by B deficiency and (ii) to provide an update on recent findings that could help to understand how the signal(s) triggered by B deficiency is transferred to the nucleus to modulate gene expression. In this contribution we review the effects of B deficiency on the transcript level of genes related to B uptake and translocation, maintenance of cell wall and membrane function, nitrogen assimilation and stress response. In addition, we discuss the possible mediation of calcium, arabinogalactan-proteins and other cis-diol containing compounds in the signaling mechanisms that transfer the signal of B deficiency to nuclei. Finally, we conclude that the advance in the knowledge of the molecular basis of B deficiency response in plants will allow improving the tolerance of crops to B deficiency stress.
