Abstract
Heat stress (HS) can cause a series of stress responses, resulting in numerous negative effects on the body, such as the diminished food intake, carcass quality and reproductive capacity. In addition to the negative effects on the peripheral system, HS leads to central nervous system (CNS) disorders given its toll on neuroinflammation. This neuroinflammatory process is mainly mediated by microglia and astrocytes, which are involved in the activation of glial cells and the secretion of cytokines. While the regulation of inflammatory signaling has a close relationship with the expression of heat shock protein 70 (Hsp70), HS-induced neuroinflammation is closely related to the activation of the TLR4/NF-κB pathway. Moreover, oxidative stress and endoplasmic reticulum (ER) stress are key players in the development of neuroinflammation. Chromium (Cr) has been widely shown to have neuroprotective effects in both humans and animals, despite the lack of mechanistic evidence. Evidence has shown that Cr supplementation can increase the levels of insulin-like growth factor 1 (IGF-1), a major neurotrophic factor with anti-inflammatory and antioxidant effects. This review highlights recent advances in the attenuating effects and potential mechanisms of Cr-mediated IGF-1 actions on HS-induced neuroinflammation, providing presently existing evidence supporting the neuroprotective role of Cr.

Chromium Exposure in Late Gestation Period Caused Increased Levels of Cr in Brain Tissue: Association with Alteration of Activity and Gene Expression of Antioxidant Enzymes of F1 and F2 Generation Mice.

Abstract
Chromium is a micronutrient which has found frequent use as supplements during pregnancy and could have a role in altering the antioxidant status in the brain. The present study was undertaken to estimate chromium levels in the brain, antioxidant enzyme activity with their gene expression, and learning and memory parameters on F1 and F2 generation mice when the F0 was exposed to chromium. The chromium levels in the brain were estimated using atomic absorption spectrophotometer. The enzyme activity of glutathione-s-transferase (GST) and catalase (CAT) was estimated and their gene expression was evaluated using RT-PCR. The spatial memory was tested using Morris water maze. The learning and recall memory was tested using the step down latency paradigm. The chromium levels were significantly raised in animals treated with Cr per se in F1 generation and quercetin cotreatment reduced the Cr levels in brain significantly. The enzyme activity of GST was significantly less in Cr-treated animals of both generations and this effect was significantly reversed on cotreatment with quercetin. The gene expression of GST matched the enzyme activity. However, catalase activity did not show significant decrease with Cr but cotreatment with quercetin resulted in significant decrease compared with control and this effect was not matched by its gene expression. We observed no significant change in learning and memory parameters in both generations following Cr exposure. Thus, this study demonstrates that chromium exposure in gestation causes changes in enzyme activity especially GST and this change was matched by change in gene expression in GST but not CAT. There was no effect on memory at the given dose.

The addition of an amylopectin/chromium complex to branched-chain amino acids enhances muscle protein synthesis in rat skeletal muscle. J Int Soc Sports Nutr 2020; 17:26. [PMID: 32460884 PMCID: PMC7251890 DOI: 10.1186/s12970-020-00355-8] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/27/2019] [Accepted: 05/10/2020] [Indexed: 01/10/2023] Open
Abstract
BACKGROUND A previous clinical study reported that the addition of an amylopectin/chromium complex (ACr; Velositol®) to 6 g of whey protein (WP) significantly enhanced muscle protein synthesis (MPS). Branched-chain amino acids (BCAAs) are also well-known to enhance MPS. The aim of this study was to determine if the addition of ACr to BCAAs can enhance MPS and activate expression of the mammalian target of the rapamycin (mTOR) pathway compared to BCAAs and exercise alone in exercise-trained rats. METHODS Twenty-four male Wistar rats were randomly divided into three groups (n = 8 per group): (I) Exercise control, (II) Exercise plus BCAAs (0.465 g/kg BW, a 6 g human equivalent dose (HED)), and (III) Exercise plus BCAAs (0.465 g/kg BW) and ACr (0.155 g/kg BW, a 2 g HED). All animals were trained with treadmill exercise for 10 days. On the day of the single-dose experiment, rats were exercised at 26 m/min for 2 h and then fed, via oral gavage, study product. One hour after the consumption of study product, rats were injected with a bolus dose (250 mg/kg BW, 25 g/L) of phenylalanine labeled with deuterium to measure the fractional rate of protein synthesis (FSR). Ten minutes later, muscle tissue samples were taken to determine MPS measured by FSR and the phosphorylation of proteins involved in the mTOR pathway including mTOR, S6K1, and 4E-BP1. RESULTS ACr combined with BCAAs increased MPS by 71% compared to the exercise control group, while BCAAs alone increased MPS by 57% over control (p < 0.05). ACr plus BCAAs significantly enhanced phosphorylation of mTOR, S6K1 and 4E-BP1 compared to exercise control rats (p < 0.05). The addition of ACr to BCAAs enhanced insulin levels, mTOR and S6K1 phosphorylation compared to BCAAs alone (p < 0.05). Serum insulin concentration was positively correlated with the levels of mTOR, (r = 0.923), S6K1 (r = 0.814) and 4E-BP1 (r = 0.953). CONCLUSIONS In conclusion, the results of this study provide evidence that the addition of ACr to BCAAs significantly enhances exercise-induced MPS, and the phosphorylation of mTOR signaling proteins, compared to BCAAs and exercise alone.

Abstract
Disturbances of diet during pregnancy and early postnatal life may impact colonization of gut microbiota during early life, which could influence infant health, leading to potential long-lasting consequences later in life. This is a nonsystematic review that explores the recent scientific literature to provide a general perspective of this broad topic. Several studies have shown that gut microbiota composition is related to changes in metabolism, energy balance, and immune system disturbances through interaction between microbiota metabolites and host receptors by the gut-brain axis. Moreover, recent clinical studies suggest that an intestinal dysbiosis in gut microbiota may result in cognitive disorders and behavioral problems. Furthermore, recent research in the field of brain imaging focused on the study of the relationship between gut microbial ecology and large-scale brain networks, which will help to decipher the influence of the microbiome on brain function and potentially will serve to identify multiple mediators of the gut-brain axis. Thus, knowledge about optimal nutrition by modulating gut microbiota-brain axis activity will allow a better understanding of the molecular mechanisms involved in the crosstalk between gut microbiota and the developing brain during critical windows. In addition, this knowledge will open new avenues for developing novel microbiota-modulating based diet interventions during pregnancy and early life to prevent metabolic disorders, as well as neurodevelopmental deficits and brain functional disorders.

Abstract
UNLABELLED Chromium is an essential trace element with anti-diabetic and anti-depressant effect; the latter is considered related to chromium properties of increasing brain serotonin. Cr3+ salts were shown to improve some forced swimming-parameters and to induce rewarding effects, which are additive to those of morphine, but Cr effect on addictive processes has not been tested. AIM The present study aimed to assess chromium picolinate (CrPi) influence on morphine-dependence in rats. MATHERIAL AND METHODS We used five groups of 10 rats. Groups 1 and 2 (controls) received saline, respectively CrPi, 0.01 mg/kg/day, for 10 days. In groups 3, 4 and 5 dependence was induced with progressively-increased morphine doses (from 5 - day 1-90 mg/kg/day - day 10, s.c.). Group 3 received only morphine, while groups 4 and 5 received CrPi, i.p., 10 and respectively 5 μg/kg/day, during the 10 days of dependence induction. On day 11, groups 3, 4, and 5 were administered 90 mg/kg morphine, and, 2 h later, all rats received naloxone, 2 mg/kg s.c., to precipitate withdrawal. We compared withdrawal intensity in group 3 vs. groups 4 and 5, assessing both individual symptoms and Gellert-Holtzman global withdrawal score. Upon rats sacrifice at the end of the experiments, brain serotonin (5HT) in certain areas and serum Cr were assessed. RESULTS Some withdrawal signs were unequally influenced by CrPi: compulsive mastication was reduced by both CrPi doses (p < 0.05), while teeth chattering and grooming were significantly reduced only by the higher dose (p < 0.05). Withdrawal score was reduced by both CrPi doses: from 132.4 ± 9.87 - group 3 to 122.2 ± 6.47 - group 4 (p < 0.01 vs. group 3) and 124.1 ± 8.41 - group 5 (p < 0.05 vs. group 3). CrPi reduction of withdrawal is accompanied by increased brain 5 H T, mainly in the prefrontal cortex (646.3 ± 8.51 - group 3 vs. 661.5 ± 14.63 - group 4, p < 0.01 and 660.7 ± 14.01 pg/mg tissue - group 5, p < 0.05 vs. group 3). CrPi also increases brain 5 H T in non-dependent rats (prefrontal cortex: 541.6 ± 31.80, group 1 and 565.5 ± 16. 46 pg/mg tissue, group 2, p < 0.05). Administration of CrPi determined a dose-dependent increase of serum Cr. CONCLUSIONS Our study evidenced a slight, but significant reduction of morphine dependence in rats induced by chromium picolinate, accompanied by increased brain serotonin. This might be considered a supplementary evidence for chromium anti-depressant effect and its serotonin-mediated mechanisms.

Abstract
Boron is increasingly added to food supplements due to multiple effects that have been reported in mammals after boric acid administration. Among these effects are inflammatory process control, bone and muscle strength enhancement, protein expression regulation, and a decreased risk of developing some pathologies in which these processes are key, such as osteoporosis, dermatological inflammatory non-infectious maladies and diseases affecting the central nervous system. Experimental data have suggested that steroid hormone levels in plasma change after boric acid administration, but a clear mechanism behind these variations has not been established. We analyzed possibilities for these changes and hypothesized that boric acid disrupts the interactions between steroid hormones and several carriers in plasma. In particular, we proposed that there is an uncoupling of the interactions between sex hormone binding globulin (SHBG) and estrogens and testosterone and that there are alterations in the binding of hydrophobic ligands by other carrier proteins in plasma. Further experimental and computational studies are required to support the hypothesis that boric acid and probably other boron-containing compounds can displace steroid hormones from their plasma carriers. If such phenomena are confirmed, boron administration with a clear mechanism could be employed as a therapeutic agent in several diseases or physiological events that require modulation of steroid hormone levels in plasma.

Abstract
The use of boron preparations (borax and boric acid) in medicine began long before their isolation in pure form. The mineral water of boron-containing sources has been historically used to treat skin diseases, to wash eyes, to disinfect wounds, etc. Also, what is of interest in the context of this article, boron-containing waters were used as calming, anti- anxiety, anticonvulsant and sleep-promoting remedy. In 1777, boric acid was first isolated from the mineral water of a healing spring source in Florence. Historically, first name of this compound was sal sedativum (“soothing salt”). However, the discovery of boron toxicity led to the cessation of its internal use. In recent decades, it has been found that boron is a microelement necessary for many metabolic processes in the body. It affects memory, cognitive functions, anxiety level, sleep, mood, regulates calcium and magnesium exchange, metabolism of vitamin D and sex steroids. It has been shown that some cases of treatment resistance to standard therapy, for example in epilepsy, anxiety and depression, are related to boron deficiency. In this regard, interest in the use of boron preparations in psychiatry and neurology, but in much smaller doses and on new scientific grounds, flared up again.
