Abstract
Spinal cord injury (SCI) results in a large amount of tissue cell debris in the lesion site, which interacts with various cytokines, including inflammatory factors, and the intrinsic glial environment of the central nervous system (CNS) to form an inhibitory microenvironment that impedes nerve regeneration. The efficient clearance of tissue debris is crucial for the resolution of the inhibitory microenvironment after SCI. Macrophages are the main cells responsible for tissue debris removal after SCI. However, the high lipid content in tissue debris and the dysregulation of lipid metabolism within macrophages lead to their transformation into foamy macrophages during the phagocytic process. This phenotypic shift is associated with a further pro-inflammatory polarization that may aggravate neurological deterioration and hamper nerve repair. In this review, we summarize the phenotype and metabolism of macrophages under inflammatory conditions, as well as the mechanisms and consequences of foam cell formation after SCI. Moreover, we discuss two strategies for foam cell modulation and several potential therapeutic targets that may enhance the treatment of SCI.

Abstract
D-pinitol (DP) has been extensively regarded as the main active component of legumes for anti-aging. In this study, we intended to explore the anti-aging mechanism of DP, utilizing computer modeling techniques. The results demonstrated that DP significantly delayed H2O2-induced cellular senescence. Model PC12 cells treated with DP exhibited increased cell viability, increased antioxidant enzyme activity (SOD, CAT), and reduced ROS and MDA levels. Furthermore, DP was discovered to have a positive effect on healthy longevity. In C. elegans, DP treatment enhanced lifespan, stress capacity, antioxidant capacity (T-SOD/CAT/GSH-Px/MDA/ROS), and altered aging-related indicators of lipofuscin accumulation, pharyngeal pump rate, motility, and reproduction. Moreover, DP could reduce the toxicity Aβ in transgenic C. elegans CL4176, CL2355, and CL2331. Further mechanistic studies indicated DP increased transcription factor (daf-16, skn-1, hsf-1) expression of insulin/insulin-like growth factor-1 signaling (IIS) pathway. As expected, DP also extended the downstream target genes of the three transcription factors (sod-3, ctl-1, ctl-2, gst-4, hsp-16.1, and hsp-16.2). Further mutant lifespan experiments, network pharmacology, and molecular docking revealed that DP might be life-extending through the IIS pathway. DP deserves extensive investigation and development as a potential anti-aging drug in the future.

Abstract
Purpose Diabetes can cause hippocampal damage and lead to cognitive impairment. Diabetic cognitive impairment (DCI) is a chronic complication of diabetes associated with a high disability rate; however, its pathogenesis and therapeutic targets are unclear. We aimed to explore the mechanism of hippocampal damage during diabetes and evaluate the potential role of D-pinitol (DP) in protecting hippocampal tissue and improving cognitive dysfunction. Methods DP (150 mg/kg/day) was administered intragastrically to streptozocin-induced aging-accelerated mice for 8 weeks. Hippocampal tissues were examined using tandem mass tag (TMT)-based proteomics and liquid chromatography-mass spectrometry (LC-MS)/MS-based non-targeted metabolomic analysis. Differentially expressed proteins (DEPs) and differentially regulated metabolites (DRMs) were screened for further analysis, and some DEPs were verified using western blotting. Results Our results showed that 329 proteins had significantly altered hippocampal expression in untreated diabetic mice (DM), which was restored to normal after DP treatment in 72 cases. In total, 207 DRMs were identified in the DM group, and the expression of 32 DRMs was restored to normal post-DP treatment. These proteins and metabolites are involved in metabolic pathways (purine metabolism, arginine and proline metabolism, and histidine metabolism), actin cytoskeleton regulation, oxidative phosphorylation, and Rap1-mediated signaling. Conclusions Our study may help to better understand the mechanism of diabetic hippocampal damage and cognitive impairment and suggest a potential therapeutic target.

Abstract
In recent years, the application of phytochemicals to prevent or treat diseases has received greater attention. These phytochemicals have little or no toxicity against healthy tissues and are thus considered as ideal compounds. An impressive number of modern drugs are obtained from natural sources based on their traditional value. D-Pinitol is a natural compound that is derived from soy and soy products. It is a potentially active molecule that belongs to the class of inositols. D-pinitol has been pharmacologically evaluated for its potent antioxidant, anti-diabetic, anti-inflammatory, anti-cancer, hepatoprotective, cardioprotective, renoprotective, neuroprotective, immunosuppressive, and anti-osteoporotic efficacies. This review is an attempt to validate the plausible pharmacological effects of D-pinitol using various in vivo and in vitro studies. PRACTICAL IMPLICATIONS: The consumption of plant-based products has been significantly increased all over the world. The active phytochemicals that are found in plants are stated to have numerous health promoting functions for the treatment of diabetes, cancer, inflammation, cardiac diseases, liver dysfunction, and many other. D-Pinitol is abundantly present in soybeans that possess notable therapeutic activities. Understanding the effects of D-Pinitol would potentially help in applying this compound in clinical research for the treatment of different disorders.

Abstract
Carob is one of the major food trees for peoples of the Mediterranean basin, but it has also been traditionally used for medicinal purposes. Carob contains many nutrients and active natural products, and D-Pinitol is clearly one of the most important of these. D-Pinitol has been reported in dozens of scientific publications and its very diverse medicinal properties are still being studied. Presently, more than thirty medicinal activities of D-Pinitol have been reported. Among these, many publications have reported the strong activities of D-Pinitol as a natural antidiabetic and insulin regulator, but also as an active anti-Alzheimer, anticancer, antioxidant, and anti-inflammatory, and is also immune- and hepato-protective. In this review, we will present a brief introduction of the nutritional and medicinal importance of Carob, both traditionally and as found by modern research. In the introduction, we will present Carob’s major active natural products. The structures of inositols will be presented with a brief literature summary of their medicinal activities, with special attention to those inositols in Carob, as well as D-Pinitol’s chemical structure and its medicinal and other properties. D-Pinitol antidiabetic and insulin regulation activities will be extensively presented, including its proposed mechanism of action. Finally, a discussion followed by the conclusions and future vision will summarize this article.

Abstract
Hepatic ischemia-reperfusion injury (IRI) is a major unavoidable clinical problem
often accompanying various liver surgery and transplantation.
d-Pinitol, a cyclic polyol, exhibits hepatoprotective efficacy. The
objective of this study is to determine the possible mechanism of action of
pinitol against endoplasmic reticulum (ER) stress regulation-mediated hepatic
IRI and compare its effects with thymoquinone (TQ) in experimental rats. Male
Sprague Dawley rats were pre-treated orally with either vehicle (DMSO) or
d-Pinitol (5, 10, and 20 mg/kg) or TQ (30 mg/kg) for 21 days and
subjected to 60 min of partial hepatic ischemia followed by 24 h of reperfusion.
Pre-treatment with pinitol (10 and 20 mg/kg) effectively
(P < 0.05) protected against
IRI-induced hepatic damage reflected by attenuation of elevated oxidative stress
and pro-inflammatory cytokines. Additionally, western blot and ELISA analyses
suggested that pinitol significantly
(P < 0.05) down-regulated expression of
endoplasmic reticulum stress apoptotic markers, namely glucose-regulated protein
(GRP)-78, CCAAT/enhancer-binding protein homologous protein (CHOP), activating
transcription factor (AFT)-4 and -6α, X-box binding protein-1, and caspase-3, 9,
and 12. Additionally, pinitol pre-treatment effectively
(P < 0.05) improved mitochondrial
function and phosphorylation of Extracellular signal-regulated kinase (ERK)-1/2
and p38. Pinitol markedly (P < 0.05)
protected hepatic apoptosis determined by flow cytometry. Further, pinitol
provided effective (P < 0.05) protection
against hepatic histological and ultrastructural aberrations induced by IRI. TQ
showed more pronounced protective effect against attenuation of IRI-induced
hepatic injury as compared to d-Pinitol. Pinitol offered protection
against endoplasmic reticulum stress-mediated phosphorylation of ERK1/2 and p38,
thereby inhibiting AFT4-CHOP/GRP78 signaling response and caspase-3 induced
hepatocellular apoptosis during hepatic ischemia-reperfusion insults. Thus,
Pinitol can be considered as a viable option for the management of hepatic
IRI.

Abstract
The rigorous design of preclinical experimental studies of candidate neuroprotectants for the treatment of acute ischemic stroke is crucial for the success of subsequent randomized clinical trials. The efficacy of Ginkgo biloba extracts (GBEs) in complex mixtures for the treatment of acute ischemic stroke remains unclear. In this preclinical randomized controlled trail (pRCT), the effects of a novel (n)GBE containing pinitol versus traditional (t)GBE without pinitol were evaluated on the mouse models of acute transient and permanent stroke, separately. The sample size, an important aspect of study design, was calculated based on our experimental data. Mice with ischemia that were induced by transient middle cerebral artery occlusion (tMCAO) or permanent distal middle cerebral artery occlusion (pdMCAO), were treated with vehicle, nGBE, tGBE, or pinitol alone by tail-vein injection. Our results showed that nGBE significantly reduced infarct size in mice with tMCAO compared with vehicle-treated control mice. Both nGBE and tGBE significantly reduced infarct size in mice with pdMCAO compared with the vehicle-treated controls. None of the three treatments rescued weight loss or prevented the neurological deficits in either the tMCAO- or pdMCAO-model mice. These findings suggest that nGBE, which includes all of the components of tGBE and pinitol, is neuroprotective in two ischemic stroke models. Additional studies of complex GBE mixtures for stroke treatment compared to single component medications are undergoing evaluation.
