Abstract Pesticides have a wide range of infertility in female reproductive. GLP is the most common herbicide used worldwide. The present study tended to evaluate the effects of alpha-lipoic acid (ALA) on expression of folliculogenesis genes in human granulosa cells (GCs) treated with glyphosate. In this study, GC samples were taken from infertile male patients who had tubal factors and received ICSI or IVF treatment for the first time. The medium used to culture cells was DMEM-F12 containing FBS 10%, penicillin 1%, and streptomycin 1%. The cells were treated with glyphosate (GLP) (250 µg/ml), ALA (50 µg/ml), and their mixture (250 GLP + 50 ALA) for 24 hr. The FoxO1, NOX4, Vnn1, and STAR gene expression in GCs was determined by real-time PCR. Exposure to GLP decreased gene expression Vnn1 and STAR in the GCs, while in comparison to control group, FOXO1 and NOX4 expression insignificantly increased. Further, ALA treatment decreased FOXO1, NOX4, in the GCs, and increased VNN1 and STAR gene expression. Transcriptional expression of FoxO1, NOX4 and STAR in GCs also decreased in their combinations (GLY + ALA). At the same time, the level of Vnn1 mRNA in GCs was increased. The findings showed that exposure to GLP alters the morphological structure of GCs and the expression of follicogenic genes, leading to dysfunction of the reproductive system. Moreover, the results showed that cell characteristics were preserved efficiently in human GCs exposed to ALA as an antioxidant.

Background: Myeloperoxidase (MPO) is involved in the initiation, progression, and complications of atherosclerosis in diabetic patients. Objectives: In the current study, the impact of alpha-lipoic acid (LA), a natural antioxidant and a cofactor in the enzyme complexes on MPO, catalase (CAT) and glutathione peroxidase (GPx) activity, glutathione (GSH) and malondialdehyde (MDA) level, histopathology of kidney and expression of antioxidant enzymes, superoxide dismutase (SOD), GPx and CAT which are involved in the detoxification of reactive oxygen species (ROS), was evaluated in alloxan-induced diabetic rats. Materials and Methods: In this study, 30 male Rattus norvegicus rats randomly divided into three groups; control (C), non-treated diabetic (NTD), and LA-treated diabetics (LATD) was induced by alloxan monohydrate (100mg/kg; subcutaneous [SC]). Then treatment was performed with alphaLA (100 mg/kg intraperitoneal (i.p) daily to 6 weeks). Blood sample of animals collected to measure levels of MPO, CAT and GPx activity GSH and MDA. Kidney paraffin sections were prepared to estimate histological studies and to measure quantitative gene expression SOD, GPX and CAT in kidney. Results: Induction of diabetes led to a significant increase in MPO and MDA, reduced GSH level and GPx and CAT activities (P < 0.05). However, treatment with alpha-LA led to a significant elevation in GPx, CAT and GSH levels with a reduction in MPO activities and MDA levels (P < 0.05). Furthermore, the real-time reverse transcriptase-polymerase chain reaction (RT-PCR) analysis results showed increased expressions of GPx, CAT and SOD enzyme in the treatment group compared with the diabetic control group. Histopathological lesions such as increased glomerular volume and lymphocyte infiltration were attenuated in the alpha-LA treated group. Conclusions: Our findings indicated that alpha-LA supplementation is effective in preventing complications induced by oxidative stress and atherosclerosis in diabetic rats.

Infertility is a problem for husband and wife, in the last 20 years the number of infertile couples has tended to increase by around 6.5 million pairs. The infertile couple can use the intrauterine insemination method to obtain offspring if a conventional method approach cannot be performed. Insemination requires a sperm preparation stage in which there are centrifugation and resuspension procedures that tend to produce excess reactive oxygen species (ROS). Excessive ROS will damage the motility of the spermatozoa. This study aims to prove the addition of alpha lipoic acid (ALA) as an antioxidant in the process of sperm preparation to improve and maintain better sperm motility. This research is a laboratory study with an experimental research design. The sample consisted of 10 infertile men who visited the Andrology section of the Sayyidah Jakarta Mother and Child Hospital (RSIA), where each ejaculate from the patient would be divided into 3 groups namely (k1) fresh semen as a control group, (k2) sperm preparation group without ALA, (k3) group of sperm preparation with the addition of ALA. The motility of spermatozoa was observed with the WHO 1999 method for 4 hours in units of percent. Progressive motility in k3 (47.95 ± 3.617) was higher than in k2 (38.05 ± 3.278) statistically significantly different after 3 hours of observation (p<0.0001). Progressive motility in k3 (78.8 ± 5.841) was higher than k1 (56.55 ± 7.511) from the initial observation (p <0.0001). The progressive motility of k2 (76.05 ± 6.768) was higher than k1 (56.55 ± 7.511) from the start of the observation (0.0001). It can be concluded that the addition of ALA in the sperm preparation process increases and maintains progressive motility that is better than sperm preparation without ALA addition after 3 hours of observation.

SummaryAlpha-lipoic acid (ALA) is known to be a natural antioxidant. The aim of the present study was to evaluate the cryoprotective effect of ALA on the motility of boar spermatozoa and its antioxidant effect on boar spermatozoa during freezing–thawing. Different concentrations (2.0, 4.0, 6.0, 8.0 or 10.0 mg/ml) of ALA were added to the extender used to freeze boar semen, and the effects on the quality and endogenous antioxidant enzyme activities of frozen–thawed spermatozoa were assessed. The results indicated that the addition of ALA to the extender resulted in a higher percentage of motile spermatozoa post-thaw (P < 0.05). The activities of superoxide dismutase, lactate dehydrogenase, glutamic-oxaloacetic transaminase and catalase improved after adding ALA to the extender (P < 0.05). Artificial insemination results showed that pregnancy rate and litter size were significantly higher at 6.0 mg/ml in the ALA group than in the control group (P < 0.05). In conclusion, ALA conferred a cryoprotective capacity to the extender used for boar semen during the process of freezing–thawing, and the optimal concentration of ALA for the frozen extender was 6.0 mg/ml.

Microarray analysis was used to compare the gene expression of granulosa cells from dominant follicles with that of those after superstimulatory treatment. Cows were allocated randomly to two groups (superstimulation and control, n=6/group). A new follicular wave was induced by ablation of follicles ≥5 mm in diameter, and a progesterone-releasing device controlled internal drug release (CIDR) was placed in the vagina. The superstimulation group was given eight doses of 25 mg FSH at 12-h intervals starting from the day of wave emergence (day 0), whereas the control group was not given FSH treatment. Both groups were given prostaglandin F2α twice, 12 h apart, on day 3 and the CIDR was removed at the second injection; 25 mg porcine luteinizing hormone (pLH) was given 24 h after CIDR removal, and cows were ovariectomized 24 h later. Granulosa cells were collected for RNA extraction, amplification, and microarray hybridization. A total of 190 genes were downregulated and 280 genes were upregulated. To validate the microarray results, five genes were selected for real-time PCR (NTS, FOS, THBS1, FN1, and IGF2). Expression of four genes increased significantly in the three different animals tested (NTS, FOS, THBS1, and FN1). The upregulated genes are related to matrix remodeling (i.e. tissue proliferation), disturbance of angiogenesis, apoptosis, and oxidative stress response. We conclude that superstimulation treatment i) results in granulosa cells that lag behind in maturation and differentiation (most of the upregulated genes are markers of the follicular growth stage), ii) activates genes involved with the NFE2L2 oxidative stress response and endoplasmic reticulum stress response, and iii) disturbs angiogenesis.

Background. The effective treatment of the hand-foot syndrome is a necessary component of the complex treatment of patients receiving antitumor therapy with multikinase inhibitors. Aims. The assessment of a new effective method for the treatment of palm-plantar syndrome in patients receiving multi-kinase inhibitors. Materials and methods. There are 27 patients received antitumor treatment with multi-kinase inhibitors and had clinical manifestations of the hand-foot syndrome (HFS) for observation. The main group (14 patients) used a combination of an alpha-lipoic acid at a dose of 600 mg per day per os and an ointment containing 0.005% calcipotriol and 0.05% betamethasone dipropionate 2 times a day. The control group, included 13 patients, used a combination with a cream containing 10% urea and ointment containing 0.05% betamethasone dipropionate. Results. After a week of treatment, the regression of the skin process was observed in both groups, but it was more evident in the main group: significant differences in severity of erythema, paresthesia, pain and burning sensation, the Dermatological Life Quality Index (DLQI) were observed at this stage of therapy (p < 0.05). After 2 weeks of therapy: a more positive trend in the main group in terms of erythema, paresthesia and burning, but the most significant difference is DLQI – 17.4 in the main group and 22.8 in the control group (p < 0.0001). At the end of the 3rd week of therapy: differences with the main characteristics of erythema, desquamation, paresthesia (p < 0.0008), pain (p < 0.0001), DLQI (p < 0.0001). At the end point of the study (after 4 weeks of therapy), significant differences were found in reducing the symptoms and the main parameters for evaluating the effectiveness of DLQI in patients of the main group with a reliability of p < 0.0001. The high correlation of DLQI was found with erythema, pain, burning, paresthesia and desquamation. Conclusions. The treatment of the hand-foot plantar syndrome combined using alpha-lipoic acid inside and topical therapy in the form of an ointment containing calcipotriol and betamethasone dipropionate, can be recommended for patients receiving targeted therapy with multi-kinaseinhibitors.

The aim of the study was to evaluate the effectiveness of the antioxidant alpha–lipoic acid in peritoneal dialysis (PD) patients taking into account the state of lipid peroxidation (LPO) and antioxidant protection (AOP) before and after treatment. Patients and methods. The research revealed the intensity of oxidative processes in 20 patients treated with continuous ambulatory peritoneal dialysis (CAPD) on the basis of а–lipoic acid applied parenterally in a dose of 600 mg for 2–weeks followed by a transfer to the 6 weeks of oral reception. The intensity of oxidative processes was evaluated before and after treatment through determining the content of MDA in serum (MDAs) and erythrocytes (MDAe). AOP activity was evaluated by the content of the antioxidant enzyme ceruloplasmin (CP), transferrin (Tr), SH–groups and total peroxidase activity (TPA) of red blood cells. The control group consisted of30 individuals comparable on for age and sex. Results. The effects on the study of PD patients (positive decrease of MDAs, increase in CP higher than control group, a significant increase in the content of SH–groups (p=0,04), TPA (p=0,009), Tr (p=0,002) and catalase serum) demonstrated a considerable positive dynamics of LPO /AOP influenced by the use of а–lipoic acid. Conclusions. The research opens up the prospect for further study ofLPO /AOP blood in PD patients and proves the application expediency of alpha–lipoic acid for this group. Use of the latter lowers the activity of oxidative processes significantly and restores AOP indicators substantially, which in turn minimizes the negative influence of oxidative stress on a patient’s body.

Abstract Background: The anti-obesity effects of Alpha-lipoic acid (α-LA) and isotonic contraction has been reported. However, the underlying mechanism is not fully understood. This study aimed to investigate the effect of α-LA supplementation and Faradic (an electrical stimulating system) on anthropometric parameters, body composition, VEGF, Sirtunin-1, nitric oxide (NO), and PGC1-α in obese people undergoing a weight loss regime.Methods: This randomized clinical trial was carried out on 100 obese adults. The subjects were randomly assigned to four groups of 25 subjects including Faradic, α-LA, -α-LA+Faradic, and control. A Bio Impedance Analyzer (BIA) was used to estimate anthropometric measurements including weight, body mass index (BMI), fat mass, and fat free mass. The serum levels of Sirtunin-1, PGC1-α, VEGF, and NO levels were measured. All measurements were done at baseline and after 8 weeks of intervention.Results: A significant weight reduction was observed in all four groups compared to baseline (p=<0.01). The placebo group had significantly higher weight, BMI, weight circumstance (WC), and body fat (BF) compared with the other groups. The α-LA+Faradic group had significantly lower weight, BMI, BF, WC than control, faradic, and α-LA groups and higher, Sitruin,, and PGC than the control group (all P <0.05).Conclusions: The findings indicated that the α-LA and Faradic interventions may have a synergistic effect on weight, BMI, BF, WC, and SLM, possibly through changes in serum level of VEGF, NO, and PGC. Further researches are warranted to clarify the mutual effects of –α-LA and Faradic on obesity and molecular biomarkers.Name of the registry: Iranian Registry of Clinical TrialsTrial registration number: IRCT20131117015424N2Date of registration: https://www.irct.ir/search/result?query=IRCT20131117015424N2URL of trial registry record: 04/04/2018
