Abstract
Cytarabine, an anti-metabolite drug, remains the mainstay of treatment for hematological malignancies. It causes various toxic effects including teratogenicity. Alpha lipoic acid (ALA) is a natural antioxidant reported to offer protection against hepatotoxicity induced by various pathological conditions, drugs, or chemicals. We investigated the protective effect of ALA against prenatal cytarabine exposure-induced hepatotoxicity in rat female neonates. A total of 30 dams were randomly assigned to five groups and received normal saline, ALA 200 mg/kg, cytarabine 12.5 mg/kg, cytarabine 25 mg/kg, and cytarabine 25 mg/kg + ALA 200 mg/kg, respectively, from gestational day (GD)8 to GD21. Cytarabine and ALA were administered via intraperitoneal and oral (gavage) routes, respectively. On postnatal day (PND)1, all the live female neonates (pups) were collected and weighed. The blood and liver from pups were carefully collected and used for histopathological, and biochemical evaluations. A significant and dose-dependent decrease in maternal food intake and weight gain was observed in the pregnant rats (dams) of the cytarabine groups as compared to the dams of the control group. The pups exposed to cytarabine showed a significant and dose-dependent (a) decrease in body weight, liver weight, hepatosomatic index, catalase, superoxide dismutase, glutathione, glutathione peroxidase, serum albumin levels and (b) increase in malondialdehyde, alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase, AST/ALT ratio, and histopathological anomalies. Maternal co-administration of ALA ameliorated these biochemical changes and histopathological abnormalities by combating oxidative stress. Future studies are warranted to explore the molecular mechanisms involved in the ALA's protective effects against prenatal cytarabine-induced hepatotoxicity.

[PMID: 38226638 DOI: 10.1080/17425255.2024.2306851] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/13/2023] [Accepted: 01/15/2024] [Indexed: 01/17/2024]
Abstract
INTRODUCTION This Expert Opinion covers recent updates in the use of Inositol in polycystic ovary syndrome (PCOS) and type II diabetes and gives support to researchers and clinicians. AREAS COVERED This article discusses the role of Myo-Inositol (MI) and D-Chiro-Inositol (DCI) in physiological function, the use of MI in PCOS, the risks of using DCI in reproductive conditions, the 40:1 combination of MI/DCI in PCOS. Furthermore, we discuss the issues of insulin resistance and how α-lactalbumin may increase the intestinal bioavailability of MI. The paper then transitions to talk about the use of inositols in diabetes, including type II diabetes, Gestational Diabetes Mellitus (GDM), and double diabetes. Literature searches were performed with the use of PubMed, Google Scholar, and Web of Science between July and October 2023. EXPERT OPINION Inositol therapy has grown in the clinical field of PCOS, with it demonstrating an efficacy like that of metformin. The use of α-lactalbumin has further supported the use of MI, as issues with intestinal bioavailability have been largely overcome. In contrast, the effect of inositol treatment on the different PCOS phenotypes remains an outstanding question. The use of inositols in type II diabetes requires further study despite promising analogous data from GDM.

Abstract
PURPOSE OF REVIEW Polycystic ovary syndrome (PCOS) is the most common endocrine and metabolic disorder in women of reproductive age worldwide. This disease causes menstrual, metabolic, and biochemical abnormalities such as hyperandrogenism, oligo-anovulatory menstrual cycles, polycystic ovary, hyperleptinemia, insulin resistance (IR), and cardiometabolic disorders, often associated with overweight or obesity and visceral adiposity. RECENT FINDINGS The etiology and pathophysiology of PCOS are not yet fully understood, but insulin seems to play a key role in this disease. PCOS shares an inflammatory state with other chronic diseases such as obesity, type II diabetes, and cardiovascular diseases; however, recent studies have shown that a healthy nutritional approach can improve IR and metabolic and reproductive functions, representing a valid therapeutic strategy to ameliorate PCOS symptomatology. This review aimed to summarize and collect evidence about different nutritional approaches such as the Mediterranean diet (MedDiet) and the ketogenic diet (KD), as well as bariatric surgery and nutraceutical supplementation as probiotics, prebiotics, and synbiotics, among the others, used in patients with PCOS.

Abstract
Miscarriage is the most common complication of pregnancy. The most common causes of early miscarriage are chromosomal abnormalities of the embryo, maternal endocrine abnormalities, organ malformations, and abnormal immune factors. Late miscarriages are mostly caused by factors such as cervical insufficiency. However, the causes of 50% of miscarriages remain unknown. Recently, increasing attention has been given to the role of metabolic abnormalities in miscarriage. In this review, we mainly discuss the roles of four major metabolic pathways (glucose, lipid, and amino acid metabolism, and oxidation‒reduction balance) in miscarriage and the metabolism-related genes that lead to metabolic disorders in miscarriage. Depending on aetiology, the current treatments for miscarriage include hormonal and immunological drugs, as well as surgery, while there are few therapies for metabolism. Therefore, we also summarize the drugs for metabolism-related targets. The study of altered metabolism underlying miscarriage not only helps us to understand the mechanisms involved in miscarriage but also provides an important basis for clinical research on new therapies.

Abstract
The incidence of preterm birth (PTB), delivery before 37 completed weeks of gestation, is rising in most countries. Several recent small clinical trials of myo-inositol supplementation in pregnancy, which were primarily aimed at preventing gestational diabetes, have suggested an effect on reducing the incidence of PTB as a secondary outcome, highlighting the potential role of myo-inositol as a preventive agent. However, the underlying molecular mechanisms by which myo-inositol might be able to do so remain unknown; these may occur through directly influencing the onset and progress of labour, or by suppressing stimuli that trigger or promote labour. This paper presents hypotheses outlining the potential role of uteroplacental myo-inositol in human parturition and explains possible underlying molecular mechanisms by which myo-inositol might modulate the uteroplacental environment and inhibit preterm labour onset. We suggest that a physiological decline in uteroplacental inositol levels to a critical threshold with advancing gestation, in concert with an increasingly pro-inflammatory uteroplacental environment, permits spontaneous membrane rupture and labour onset. A higher uteroplacental inositol level, potentially promoted by maternal myo-inositol supplementation, might affect lipid metabolism, eicosanoid production and secretion of pro-inflammatory chemocytokines that overall dampen the pro-labour uteroplacental environment responsible for labour onset and progress, thus reducing the risk of PTB. Understanding how and when inositol may act to reduce PTB risk would facilitate the design of future clinical trials of maternal myo-inositol supplementation and definitively address the efficacy of myo-inositol prophylaxis against PTB.

Abstract
Importance Subchorionic hemorrhage (SCH) in the second and third trimesters of pregnancy can be associated with maternal morbidity and fetal morbidity/mortality. Management of SCH in the second or third trimesters can be complicated, especially in the setting of a large SCH that requires hospitalization and blood transfusion. Objective The aim of this review is to describe SCH in second and third trimesters, risk factors, diagnosis, maternal and fetal outcomes, and management of this uncommon pregnancy complication. Evidence Acquisition A PubMed, Web of Science, and CINAHL search was undertaken with no limitations on the number of years searched. Results There were 123 abstracts and/or articles reviewed, with 48 articles being the basis of review. The only known risk factors for SCH are maternal factor deficiency and anticoagulation therapy. The diagnosis is usually made by ultrasound imaging. Subchorionic hemorrhage in second and third trimesters has been associated with several adverse fetal outcomes including preterm birth, preterm prelabor rupture of membranes, fetal growth restriction, fetal demise, and neonatal pulmonary morbidity. There is no proven treatment for SCH, although there are several investigational therapies reported. Conclusions Subchorionic hemorrhage can be complex and difficult to manage in the second and third trimesters. There are no recommendations or guidelines for management; however, serial growth ultrasounds, umbilical artery Doppler studies, and antenatal fetal testing should be considered particularly if the SCH is large or treatment requires a maternal blood transfusion. Relevance Subchorionic hemorrhage in the second and third trimester is associated with poor fetal outcomes and maternal morbidity, especially if the SCH is significant.

Abstract
Implantation is a key point in pathological processes associated with infertility, especially in endometriosis. In this complex process, there is limited evidence to demonstrate the role of receptivity and autophagy. The present study aimed to evaluate LC3A/B, P62/SQSTM1, Beclin 1, and integrin expressions and receptivity and autophagy processes in endometriosis in pregnant rats with healthy endometriosis on day 6 of the process. Pregnancy was observed in all rats in the control group (8/8), while the pregnancy was 4/8 in the endometriosis group, and 6/8 in the endometriosis + ALA group. LC3A/B and P62/SQSTM1 expression increased significantly in the endometriosis + ALA group, compared with endometriosis groups (p < .05). The effect of ALA on autophagy and receptivity in endometriosis was shown for the first time. Antioxidant and anti-inflammatory treatments in endometriosis should be investigated as new treatment modalities for implantation problems. PRACTICAL APPLICATIONS: Endometriosis, the etiology of which remains unknown, is an important cause of infertility. Implantation is the key point in pathological processes associated with infertility. In this complex process, there is limited evidence to demonstrate the role of receptivity and autophagy. The present study aimed to evaluate LC3A/B, P62/SQSTM1, Beclin 1, and integrin expressions and receptivity and autophagy processes in endometriosis in pregnant rats with healthy endometriosis on day 6 of the process. Oral alpha-lipoic acid was administered to one group and the effect of this powerful antioxidant on the process was evaluated.

Abstract
Abstract
Background
Cytarabine (Ara-C) is an anticancer drug, which is considered as the mainstay in the treatment of hematological malignancies, known to cause various teratogenic effects. Alpha-lipoic acid (ALA) is a natural antioxidant and its supplementation proved to improve pregnancy outcomes in several pathological conditions. We aimed at exploring the benefits of maternal supplementation of ALA against in-utero Ara-C exposure-induced testicular toxicity in rat fetuses.
Methods
Pregnant rats (dams) received normal saline (control group), ALA 200 mg/kg (ALA group), Ara-C 12.5 mg/kg (Ara-C 12.5 group), Ara-C 25 mg/kg (Ara-C 25 group), and Ara-C 25 mg/kg + ALA 200 mg/kg (protection group) from gestational day (GD)8 to GD21. Ara-C and ALA were administered via the intraperitoneal and oral routes, respectively. The day of parturition was considered as postnatal day (PND)1. On PND1, all the live male pups were collected. The maternal parameters evaluated include (a) food intake, (b) bodyweight, and (c) oxidative stress (OS) markers. The fetal parameters evaluated include (a) bodyweight, (b) anogenital distances (AGD), (c) testicular weight (d) testicular testosterone levels (e) testicular histopathology, and (f) morphometrical parameters.
Results
A significant and dose-dependent decrease in maternal food intake, weight gain, and an increase in oxidative stress (OS) were observed in the pregnant rats of the Ara-C groups as compared to pregnant rats of the control group. Further, a significant and dose-dependent (a) reduction in bodyweight, AGD, testicular weight, and testosterone levels, (b) increase in OS, and (c) structural and morphometrical anomalies in fetal testes were observed in fetuses of Ara-C groups as compared to fetuses of the control rats. These deleterious effects observed in the Ara-C groups were found to be diminished in the pregnant rats and fetuses of the Protection group as compared to the pregnant rats and fetuses of the Ara-C 25 group.
Conclusions
From the results of this study, we conclude that the maternal supplementation of ALA may ameliorate the Ara-C exposure-induced impairment in prenatal development and function of the testes in the rat fetuses. However, future experimental and clinical studies are warranted to explore the possible mechanisms involved in the protection offered by maternal supplementation of ALA against Ara-C induced testicular toxicity.

Abstract
INTRODUCTION Extensive evidence suggests that alpha-lipoic acid (ALA) is effective in diabetic neuropathy pain management. However, little is known on its safety and efficacy in reducing idiopathic pain in normoglycemic subjects. The aim of this study was to evaluate ALA food supplement safety and efficacy in the reduction of different forms of idiopathic pain. METHODS Two-hundred and ten normoglycemic adults suffering from idiopathic pain (i.e. 57 subjects with primitive neuropathic pain, 141 subjects with arthralgia with unknown etiology, and 12 subjects with idiopathic myalgia) were randomized to receive placebo, 400 mg/day, or 800 mg/day of ALA. Participants underwent two visits (at baseline = t0, and after 2 months = t1) in which two validated questionaries for pain (numerical rating scale [NRS] and visual analogue scale [VAS]) were collected; fasting blood glucose assessment, adverse effects, and renal and hepatic toxicity were also monitored. RESULTS At t1, none of subjects treated with ALA reported a decreased glycemia or adverse effects. The treated subjects showed a significant reduction in NRS (p < 0.001) while the placebo group did not show any NRS reduction (p = 0.86). Similar results were also obtained for VAS. Statistical analysis aimed at detecting possible differences in NRS and VAS scores among treatment groups based on the source of pain did not reveal any significant effect. CONCLUSIONS Since the management of idiopathic pain is challenging for physicians, the use of ALA food supplements could be a feasible option, based on its safety and efficacy compared to commonly-used analgesic drugs.

Abstract
α-Lipoic acid (ALA) is a natural molecule that is inconsistently synthesized by the human body and must be provided from exogenous sources, such as food and dietary supplements. Once absorbed, the oxidized form of ALA is transformed into its reduced form, dihydrolipoic acid (DHLA). ALA/DHLA exert direct and indirect antioxidant, anti-inflammatory and fine immunomodulatory effects. ALA/DHLA reduce the levels of pro-inflammatory cytokines (IL-1β, IL-6, IL-8 and IL-17), while increasing the secretion of anti-inflammatory cytokines (IL-10). They also inhibit cyclooxygenase 2, thereby decreasing the secretion of prostaglandin E2 and nitrogen oxide, and reducing the risk of miscarriage in the first trimester of pregnancy. In patients at risk of abortion, administration of ALA from the first trimester has shown efficacy by accelerating subchorionic hematoma resorption, with a significant decrease in the accompanying abdominal pain. ALA has been proven to be efficient in maintaining the length of the cervix and keeping it closed following one episode of premature labor. Preeclampsia is a dysfunction caused by abnormal placentation and an excessive maternal inflammatory response, leading to extreme hypoxia in the placental bed and exaggerated oxidative stress, with release of oxygen free radicals. Oxidative stress plays a key role in the development of preeclampsia and intrauterine growth restriction. The hypothesis of antioxidant supplementation may play an essential part in disease prevention and fetal neuroprotection.

Abstract
Oxidative stress is caused by an imbalance between the production of reactive oxygen species (ROS) in cells and tissues and the ability of a biological system to detoxify them. During a normal pregnancy, oxidative stress increases the normal systemic inflammatory response and is usually well-controlled by the balanced body mechanism of the detoxification of anti-oxidative products. However, pregnancy is also a condition in which this adaptation and balance can be easily disrupted. Excessive ROS is detrimental and associated with many pregnancy complications, such as preeclampsia (PE), fetal growth restriction (FGR), gestational diabetes mellitus (GDM), and preterm birth (PTB), by damaging placentation. The placenta is a tissue rich in mitochondria that produces the majority of ROS, so it is important to maintain normal placental function and properly develop its vascular network to ensure a safe and healthy pregnancy. Antioxidants may ameliorate these diseases, and related research is progressing. This review aimed to determine the association between oxidative stress and adverse pregnancy outcomes, especially PE, FGR, GDM, and PTB, and explore how to overcome this oxidative stress in these unfavorable conditions.

Abstract
Myo-inositol and D-chiro-inositol are insulin sensitising agents. In the ovary, myo-inositol acts as second messenger of Follicle Stimulating Hormone (FSH). Both molecules were administered to Polycystic Ovary Syndrome (PCOS) women. The gynaecologist Vittorio Unfer was the first to give specific value to myo-inositol for the treatment of PCOS: this important innovation opened new ways of research to identify efficient therapies based on myo-inositol alone or with low doses of D-chiro-inositol. Significant successes were also gained using myo-inositol in treating male and female infertility. Unfer's researches allowed to identify "the D-Chiro-Inositol Paradox in the Ovary" and the best myo-inositol/D-chiro-inositol ratio (40:1) for the treatment of PCOS. Furthermore, his studies allowed to improve the inositol's efficacy using alpha-lactalbumin. As shown in this review, the main stages of Unfer's scientific career have been closely intertwined with important phases of the recent pharmacological research about the topic.

Abstract
Threatened miscarriage is one of the most common complications causing pregnancy loss, and it affects approximately 20% of confirmed pregnancies. More and more women are seeking treatment with complementary and alternative medicine (CAM) for this common complication, and it has been reported that women have had successful pregnancies after threatened miscarriage when being treated with CAM, which mainly includes Chinese herbal medicines, acupuncture, and nutritional supplements as well as psychological interventions and other approaches. However, many experts are concerned about the safety and adverse events of certain CAM approaches in women with threatened miscarriage. Therefore, this review focuses on the status of CAM for threatened miscarriage and presents the potential therapeutic efficacy and safety of CAM based on some clinical and experimental studies. We thus hope to provide some instructive suggestions for the application of CAM for treating threatened miscarriage in the future.

Abstract
Okra (Abelmoschus esculentus [L.] Moench.) has been used as a natural drug in East or West Africa for many centuries, as well as consumed in most areas of the world as a tropical vegetable. The study aimed to evaluate whether the flavonoids of okra fruit (FOF) administration influence Aβ1-42-induced learning and memory impairment, and explore the underlying mechanisms. The Y-maze task and the Morris water maze test were used for evaluating cognition processes. The levels of tumor necrosis factor-α (TNF-α), interleukin-1β (IL-1β), superoxide dismutase (SOD), total antioxidant capacity (T-AOC), and glutathione peroxidase (GSH-Px) were detected by ELISA kits. The expressions of nuclear factor kappa-light chain-enhancer of activated B (NF-κB), brain-derived neurotrophic factor (BDNF), cAMP-response element-binding protein (CREB), extracellular signal-regulated kinase (ERK), phosphatidylinositol 3 kinase (PI3K), protein kinase B (AKT), glycogen synthase kinase-3β (GSK-3β) were studied by western blot. Histopathological changes were observed by H.E. straining. The results showed that intracerebroventricular injection of Aβ1-42 was effective in producing memory deficits in mice. Besides, Aβ1-42 exposure could significantly increase the levels of NF-κB, TNF-α, IL-1β, and decreased T-AOC, the activities of SOD and GSH-Px in the hippocampus and cortex. Furthermore, the level of BDNF was also reduced, accompanied by down-regulated CREB/ERK and PI3K/AKT/GSK-3β signaling pathways in the hippocampus and cortex. Nevertheless, chronic administration of FOF (100 or 300 mg/kg, i.g.) significantly prevented Aβ1-42-induced behavioral and biochemical alterations. It also suggested that FOF could improve the cognitive deficits in AD-like model mice, which might be mediated by regulation of BDNF levels in cortex and hippocampus and up-regulating of CREB/ERK and PI3K/AKT/GSK3β pathways, as well as alleviation of oxidative stress and neuroinflammation.

Abstract
BACKGROUND Evidence suggests that Oxidative stress has been shown to plays an important role in gestational diabetes mellitus (GDM) etiology. On the other hand, women with GDM are at an increased risk for complications such as endothelial dysfunction and cardiovascular diseases. OBJECTIVE To investigate the effects of alpha-lipoic acid (ALA) on the maternal circulating values of lipid profile and lipid ratios in women with GDM. MATERIALS AND METHODS Sixty women with GDM were participated in the present study. The ALA group (n = 30) received ALA (100 mg/day) and the placebo group (n = 30) received cellulose acetate (100 mg/day) for eight wk. The maternal circulating values of hemoglobin A1C, triglyceride (TG), total cholesterol, high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol, triglyceride-glucose (TyG) index, atherogenic index of plasma (AIP), non-HDL-C, and lipid ratios were assessed before and after the intervention. P-value < 0.05 was considered as statistically significant. RESULTS The values of TyG index (p < 0.001), TG (p = 0.006), TG/HDL-C (p = 0.003), and AIP (p = 0.005) decreased significantly in the ALA group after the intervention. CONCLUSION Maternal circulating values of TyG index, TG, TG/HDL, AIP decreased after eight wk of ALA supplementation in women with GDM.

Abstract
Cytarabine (Ara-C) is a nucleoside analogue used in the treatment of cancers and viral infections. It has teratogenic potential and causes a variety of birth defects in fetuses. Alpha-lipoic acid (ALA) is a natural antioxidant offers protection against the developmental toxicity induced by drug- or toxicant-exposure or pathological conditions. This study was aimed at evaluating the protective effect of ALA against Ara-C induced developmental toxicity in rat fetus. Pregnant rats divided into five groups and received normal saline, ALA200 mg/kg, Ara-C12.5 mg/kg, Ara-C25 mg/kg and, Ara-C25 mg/kg plus ALA200 mg/kg respectively from gestational day (GD) 8 to GD14 and sacrificed on GD21. Ara-C treatment led to a significant and dose-dependent decrease in food intake, weight gain, placental weight, and an increase in oxidative stress in pregnant rats. Further, the in-utero exposure to Ara-C led to an increase in fetal mortality, resorptions, oxidative stress, external morphological anomalies and limb abnormalities, and impaired ossification. Co-administration of ALA resulted in amelioration of the footprints of Ara-C induced toxicity in pregnant rats as well as the fetus. These findings indicate that the ALA supplementation offers protection against developmental toxicity caused by Ara-C prenatal exposure in rats.

Abstract
Alpha-lipoic acid (ALA), a multifunctional antioxidant, can promote fatty acid mobilization, energy expenditure and scavenge free radicals. The effects of dietary ALA on the reproductive performance of breeder hens were investigated in the current study. In the 5-week experiment, 180 54-week-old Qiling breeder hens were randomly divided into three treatments with five replicates and supplemented with three levels of ALA (0, 300 and 600 mg/kg) in the basic corn-soya bean meal diets. 600 mg/kg ALA treatment group (HLA) significantly improved the eggshell thickness and strength (p < .05). ALA-treated groups improved egg-laying rate compared with the CON group, but with no statistically significant difference (p > .05). The levels of HDL-C, ALB and estradiol (E2) of the serum in the HLA group were elevated compared with the CON group (p < .05). In addition, ALA (600 mg/kg) treatment exhibited a reduced level of serum AST and TG (p < .05). Dietary ALA increased the activity of hepatic lipase in liver (p < .05). Supplemental 600 mg/kg ALA also improved the SOD activity and total antioxidant capacity level, along with a decreased MDA in ovarian tissue (p < .05). Furthermore, the mRNA expressions of ESR1, ESR2, VTG2 and ApoB in the liver and FSHR in follicles were upregulated in the HLA group (p < .05). In conclusion, dietary supplementation with 600 mg/kg ALA during the late egg-laying period could improve lipid metabolism and reproductive performance of breeder hens.

Abstract
The aim of this study was to examine the effects of alpha lipoic acid (ALA) supplementation during semen cryopreservation on the sperm quality, chromatin integrity, oxidative stress, and expression level of BAX, BCL2, HSP70 and iNOS genes in semen samples obtained from infertile men with asthenoteratozoospermia. METHODS Twenty freshly ejaculated semen samples were cryopreserved with sperm freezing medium supplemented with 0.00, 0.02, 0.05, 0.1, 0.5, and 1 mmol/mL of ALA. The samples were analyzed according to the WHO guidelines before and after freezing. Sperm ROS production level, DNA fragmentation and cryo-capacitation were assessed using flow cytometry, TUNEL assay and chlortetracycline (CTC) test, respectively. Expression level of stress protein (HSP70), pro-apoptotic Bax, anti-apoptotic Bcl-2, and iNOS genes was assessed by real-time PCR assay. RESULTS The effective concentrations of ALA (0.02 and 0.5 mM) significantly improved the motility, viability and morphology of the frozen-thawed sperms compared to the control group treated with 0.00 mM of ALA. During cryopreservation, treatment of semen with 0.02 mM of ALA, as the optimal concentration, significantly decreased DNA fragmentation and oxidative stress level (P < 0.05), protected the acrosome integrity, and led to insignificant reduction in BAX gene expression level and significant increase in expression level of BCL2, HSP70, and iNOS genes compared with control group. CONCLUSION Our findings revealed that the adding ALA to semen samples obtained from infertile men with asthenoteratozoospermia plays a significant protective role against cryodamage by preserving the sperm functional parameters.

Abstract
OBJECTIVE The effects of alpha lipoic acid (ALA) and its possible mechanisms in treating Primary ovarian failure (POF) model was studied with 4 vinylcyclohexene diepoxide (VCD). MATERIAL AND METHODS Rats were divided into 4 groups (n = 7) as Control, VCD, VCD + ALA and ALA. POF model was induced by applying VCD intraperitoneally and ALA was administered by oral gavage as 100 mg/day to the VCD + ALA and ALA groups. RESULTS At the end of 42 days, ovarian and uterine tissues were received. The number of primordial and primary follicles were increased and corpus luteum and cystic follicles were decreased in ovarian tissues in VCD + ALA group compared to VCD group. Caspase-3 immunoreactivity in follicular cells was decreased in VCD + ALA group compared to VCD group. eNOS immunoreactivity and eNOS levels were decreased in VCD group and increased in VCD + ALA group while iNOS immunoreactivity and iNOS levels were increased in VCD group, decreased in VCD + ALA group in ovary and uterine tissue. Plasma FSH and LH hormone levels were increased in the VCD but decreased in VCD + ALA group. Estradiol level decreased in the VCD group compared to the other groups. The MDA values were significantly increased in the VCD + ALA group compared to VCD group. In addition, the levels of GSH values were decreased in VCD + ALA group compared to VCD group. CONCLUSION Alpha lipoic acid treatment of rats with VCD-induced POF had a beneficial effect on reducing ovarian damage by improving histological, immunohistochemical, hormone level and oxidative stress markers. Our results show that ALA is an effective treatment of VCD-induced POF rats.

Abstract
The present study was conducted to evaluate the effects of alpha-lipoic acid (ALA) on quantitative and qualitative indices of mouse embryos challenged by lipopolysaccharide (LPS). Having determined the effective concentrations of LPS (1 mg/mL) that could reduce blastocyst formation rate by around 50% and the optimal concentration of ALA (10 μM) that could attenuate the toxic effects of LPS on blastocyst formation, the following indices were defined: inner cell mass and trophectoderm cell numbers, blastocyst mitochondrial distribution, ROS and GSH levels, as well as the relative expression of Tlr-4. Nrf-2 and Tnf-RI/P-60 receptor involved in inflammatory pathways. Finally, embryos derived from the experimental and control groups were transferred to synchronized recipients and their implantation rate and post-implantation capacity were determined. Treatment with LPS resulted in an increase in intracellular ROS level (P ≤ 0.05), and remarkable decreases (P ≤ 0.05) in intracellular GSH content, mitochondrial mass, and blastocyst quality. ALA attenuated all the aforementioned negative effects of LPS. The relative expression levels of Nrf-2 and Tnf-RI/P-60 receptor (P ≤ 0.05) significantly increased in response to LPS, and treatment with ALA significantly reduced the relative expression of Tnf-RI/P-60. ALA also improved the post-implantation developmental capacity of embryos treated with LPS. In conclusion, our findings indicate that the reproductive toxicity of LPS could be overcome by ALA treatment. These effects were mainly due to the improvements made in intracellular antioxidant capacity as well as suppression of some inflammatory elements, especially the main receptor of TNF-α, the Tnf-RI/P-60, involved in induction of apoptosis. These observations have important implications for dairy farming and treatment of infertility.

Abstract
Lipoic acid (LA) is a natural compound present in food and used as a dietary supplement. LA is endogenously synthetized in small amounts from octanoid acid in the mitochondria. This compound occurs naturally in vegetables such as spinach, broccoli and in animal tissues, in the kidneys, heart and liver. It has been shown that LA is a cofactor in the multienzyme complexes that are responsible for oxidative decarboxylation of α- ketoacids. LA and its reduced form, dihydrolipoic acid (DHLA), have many biological functions leading to a wide variety of actions such as anti-inflammation and antioxidant protection, scavenging of reactive oxygen species, regenerating other antioxidant agents, such as vitamins C and E, and cytosolic glutathione, chelating the transitional metal ions (e.g. iron and copper), and modulating the signal transduction of nuclear factor. Many authors regard LA as a potentially useful agent in the treatment and/or prevention of many diseases such as diabetes mellitus, overweight, obesity, hypertension, heart diseases, inflammation. This review concentrates on the role of LA in the treatment of diabetes mellitus, obesity, inflammation and blood pressure regulation. LA can be considered as a potentially useful drug in treatment of many diseases, particularly those related to excessive production of free radicals.

Abstract
Pregnancies complicated by diabetes have largely increased in number over the last 50 years. Pregnancy is characterized by a physiologic increase in insulin resistance, which, associated with increased oxidative stress and inflammations, could induce alterations of glucose metabolism and diabetes. If not optimally controlled, these conditions have a negative impact on maternal and foetal outcomes. To date, one can resort only to diet and lifestyle to treat obesity and insulin resistance during pregnancy, and insulin remains the only therapeutic option to manage diabetes during pregnancy. However, in the last years, in a variety of experimental models, inositol and antioxidants supplementation have shown insulin-sensitizing, anti-inflammatory, and antioxidant properties, which could be mediated by some possible complementary mechanism of action. Different isomers and multiple combinations of these compounds are presently available: Aim of the present review article is to examine the existing evidence in order to clarify and/or define the effects of different inositol- and antioxidant-based supplements during pregnancy complicated by insulin resistance and/or by diabetes. This could help the clinician's evaluation and choice of the appropriate supplementation regimen.

Abstract
PROBLEM A significant increased expression/activation of one of the most well-characterized inflammasomes, the NAcht leucine-rich-repeat protein-3 (NALP-3), in the endometrium from idiopathic recurrent pregnancy loss women (RPL) has been previously found by our research group. We therefore, suggested this event as being one of the molecular mechanisms altering endometrial inflammatory status during early pregnancy. In the present research, we attempt to investigate whether molecules with anti-inflammatory activity, alpha-lipoic acid (ALA), and/or myoinositol affect the endometrial NALP-3 expression and activation. METHOD OF STUDY Women with a history of idiopathic RPL (n = 30) were included in the study and compared to a control group (n = 15). Endometrial tissues were collected by hysteroscopy during the mid-luteal phase. RPL women underwent a three-month prescription of tablets containing ALA plus myoinositol (Sinopol® ). After treatment, hysteroscopic biopsies were repeated in RPL patients. Inflammasome expression was evaluated by immunohistochemical and Western blot analysis. NALP-3 activation was studied by quantifying the secretion of both caspase-1 and interleukin (IL)-1ß and IL-18 through ELISA. In ex vivo experiments, the effects of each molecule on endometrial inflammasome were studied. RESULTS Sinopol® significantly reduced the RPL endometrial inflammasome expression and activation. ALA, but not myoinositol, significantly reduced the endometrial inflammasome expression and activity. CONCLUSION Our data suggest a role for ALA on RPL inflammasome. Understanding the mechanisms involved in RPL and the observation that specific molecules are able to interfere with such complex at the endometrium might provide new rational design approaches to a personalized evaluation of endometrial status and, ultimately, a targeted medicine.

Abstract
Alpha-lipoic acid (ALA) is a short chain fatty acid and is known as a universal antioxidant. The aim of the current clinical trial study was to explore the effects of ALA supplementation on maternal circulating values of adiponectin (A), leptin (L); and A/L, L/A, adiponectin/homeostatic model assessment for insulin resistance (A/H), and malondialdehyde/total antioxidant capacity (MDA/TAC) ratios in pregnant women with gestational diabetes mellitus (GDM). Sixty women diagnosed as GDM during 24 and 28 weeks of pregnancy were randomly divided into drug (n = 30) and placebo (n = 30) groups. They consumed ALA (100 mg) and cellulose acetate (100 mg) respectively for 8 weeks, per day. The biochemical variables were evaluated before and after the trial. Maternal fasting serum values of glucose (p < .001), HOMA-IR (p < .001), MDA/TAC (p < .001), and L/A (p = .008) were decreased while values of adiponectin (p = .011), A/L (p = .001), and A/H (p < .001) were increased in the drug group after the intervention. In summary, current study had shown that after daily supplementation with 100 mg of ALA for 8 weeks in women with GDM, maternal circulating values of adiponectin, A/L, and A/H were increased while values of L/A and MDA/TAC were decreased.

Abstract
AIM Alpha-lipoic acid (ALA) is a short chain fatty acid which has a key role in energy production. ALA is also known as a universal antioxidant. The aim of the present study was to explore the effects of ALA supplementation in women with gestational diabetes mellitus. METHODS A randomized double-blind placebo-controlled clinical trial study was designed. Women with gestational diabetes mellitus (n = 60) during 24-28 weeks of gestation were selected and divided randomly into drug (n = 30) and placebo (n = 30) groups. Drug group supplemented with ALA (100 mg/day) for 8 weeks. The biochemical markers were measured before and after the intervention and considered significant at a P-value less than 0.05. RESULTS Maternal circulating values of fasting blood sugar (P < 0.001), gamma-glutamyltransferase (P < 0.001) and alanine transaminase (P = 0.031) were decreased in the drug group after the intervention. However, values of urea, creatinine, uric acid, aspartate transaminase and alkaline phosphatase were not changed significantly after the trial. CONCLUSION The present study has shown that supplementation with 100 mg/day of ALA had some beneficial effects on glucose metabolism and liver function in women with gestational diabetes mellitus.

Abstract
Alpha-Lipoic acid (ALA) is a natural antioxidant synthetized by plants and animals, identified as a catalytic agent for oxidative decarboxylation of pyruvate and α-ketoglutarate. In this review, we analyzed the action of ALA in gynecology and obstetrics focusing in particular on neuropathic pain and antioxidant and anti-inflammatory action. A comprehensive literature search was performed in PubMed and Cochrane Library for retrieving articles in English language on the antioxidant and anti-inflammatory effects of ALA in gynecological and obstetrical conditions. ALA reduces oxidative stress and insulin resistance in women with polycystic ovary syndrome (PCOS). The association of N-acetyl cysteine (NAC), alpha-lipoic acid (ALA), and bromelain (Br) is used for prevention and treatment of endometriosis. In association with omega-3 polyunsaturated fatty acids (n-3 PUFAs) with amitriptyline is used for treatment of vestibulodynia/painful bladder syndrome (VBD/PBS). A promising area of research is ALA supplementation in patients with threatened miscarriage to improve the subchorionic hematoma resorption. Furthermore, ALA could be used in prevention of diabetic embryopathy and premature rupture of fetal membranes induced by inflamation. In conclusion, ALA can be safely used for treatment of neuropatic pain and as a dietary support during pregnancy.

Abstract
The antioxidants role in cell response regulation attracted great interest in the last decades and it is undergoing to a profound reconsideration. The mere concept of "biological antioxidant" has been frequently misconceived or misused, possibly leading to the misinterpretation of some experimental observation. Organosulfur compounds in general and α-lipoic acid, a dithiol molecule, can be considered a typical example of the kind. Reduced α-lipoic acid, dehydrolipoic acid has been in fact originally considered a bona fide, reducing, electron donor molecule. A more recent approach, according to stoichiometric and thermodynamic evidences, lead to a reinterpretation of the biochemical role of "antioxidants". The electrophilic nature of oxidized nucleophilic molecules, including α-lipoic acid, renders more plausible a mechanism based on the ability to activate Nrf2/EpRE mediated hormetic response. In this study, we demonstrate that nmolar concentrations of oxidized α-lipoic acid, but not dehydrolipoic acid, protect human umbilical primary endothelial cells (HUVEC) from TNF-α induced dysfunction, inhibit NF-κB activation and block apoptosis following the activation of Nrf2 transcription factor. Our observations corroborate the concept that the major, if not the unique, mechanism by which α-lipoic acid can non-enzymatically exert its reducing activity is related to the electrophilic nature of the oxidized form.

Abstract
α-Lipoic acid (ALA) is a safe natural molecule involved in the immunomodulation of many physiological processes. Orally administered ALA has been reported to treat several inflammatory pathologies and support pregnancy. Our study aimed at testing ALA vaginal administration in female Wistar rats evaluating its tissue distribution (experiment I), impact on implantation process (experiment II), and effectiveness in contrasting induced preterm birth (experiment III). In experiment I, rats were intravaginally treated with 50 mg/kg or 500 mg/kg ALA, or with a physiologic solution, for 4 days. α-Lipoic acid distribution in uterus and cervical tissues was evaluated by immunohistochemical analyses. In experiment II, rats received intravaginally the above treatments for 5 days, then they were mated and, if pregnant, included in the experiment to evaluate both implantation rate and the content of implantation mediators in uterus tissues. In experiment III, pregnant rats were pretreated with placebo or with vaginal ALA for 4 days and then induced to delivery with mifepristone plus PGE2 on the 19th day of pregnancy. The delivery time was recorded, and the messenger RNA (mRNA) levels of pro-inflammatory cytokines were detected in the uterine tissues by real-time polymerase chain reaction. Immunohistochemistry was also performed. Results showed that vaginal ALA was well absorbed and distributed. The treatment did not affect the implantation process and was able to significantly revert mifepristone plus prostaglandin E2 effects, delaying the timing of delivery and significantly decreasing mRNA synthesis and release of pro-inflammatory cytokines. We provide for the first time new information on vaginal ALA use, even during pregnancy, opening a perspective for further studies.

Abstract
Alpha-lipoic acid (ALA) is a pleiotropic molecule with antioxidant and anti-inflammatory properties, of which the effects are exerted through the modulation of NF-kB. This nuclear factor, in fact, modulates different inflammatory cytokines, including IL-1b and IL-6, in different tissues and cell types. We recently showed that IL-1b and IL-6 DNA methylation is modulated in the brain of Alzheimer's disease patients, and that IL-1b expression is associated to DNA methylation in the brain of patients with tuberous sclerosis complex. These results prompted us to ask whether ALA-induced repression of IL-1b and IL-6 was dependent on DNA methylation. Therefore, we profiled DNA methylation in the 5'-flanking region of the two aforementioned genes in SK-N-BE human neuroblastoma cells cultured in presence of ALA 0.5 mM. Our experimental data pointed out that the two promoters are hypermethylated in cells supplemented with ALA, both at CpG and non-CpG sites. Moreover, the observed hypermethylation is associated with decreased mRNA expression and decreased cytokine release. These results reinforce previous findings indicating that IL-1b and IL-6 undergo DNA methylation-dependent modulation in neural models and pave the road to study the epigenetic mechanisms triggered by ALA.

Abstract
The naturally occurring compound α-lipoic acid (ALA) is implicated in manifold critical biological roles and its potent antioxidant properties and potential for treatment of various diseases have led to its widespread use as a dietary supplement. However, shortcomings of poor aqueous solubility and low thermal stability have hampered its development as a medicinal agent, prompting the use of cyclodextrins (CDs) to address these problems. The paucity of published structural data on the nature of the interactions between ALA and CDs motivated the present study, which describes the synthesis and X-ray structural elucidation of crystalline inclusion complexes between the biologically relevant R-(+)-α-lipoic acid (RALA) and the host molecules permethylated α-CD (TMA) and permethylated β-CD (TMB). Single crystal X-ray diffraction of TMA·RALA·6H₂O and TMB·RALA revealed significantly different orientations of the RALA molecule within the TMA and TMB cavities, but in both cases the guest molecule is fully encapsulated by the respective parent host molecules and residues of CD molecules of neighboring complex units. While pure RALA melted at 46-48 °C, combined thermal analysis techniques indicated that on heating the respective complexes, the release of RALA occurred at significantly higher onset temperatures, in the range 150-170 °C.
