The effect of exposure to MoO3-NP and common bean fertilized by MoO3-NPs on biochemical, hematological, and histopathological parameters in rats.

Nanotechnologies has been used to introduce several beneficial tools in the agricultural field. Herein, the effect of molybdenum oxide nanoparticles (MoO3-NPs) was investigated by evaluating the hematological, biochemical, and histopathological parameters in rats orally exposed to MoO3-NPs or fed common beans (CB) fertilized by MoO3-NPs. In the first study, 18 rats were randomly divided into 3 groups: G1 (control group) was given water orally, while G2 and G3 were administered 10 and 40 ppm MoO3-NPs by oral gavage tube, respectively. There was a significant increase in the levels of alanine aminotransferase (ALT), albumin, and total protein; however, there was a a significant decrease in body weight change (BWC), alkaline phosphatase (ALP), lactate dehydrogenase (LDH), creatinine, creatine kinase-MB (CK-MB), thyroid-stimulating hormone (TSH), free triiodothyronine (FT3), and testosterone levels in G3 compared to G1. In the second study, 24 rats were divided into 4 groups: the control (C) group was fed a balanced diet, and three groups were fed on a balanced diet plus 10% CB that was fertilized with 0, 10, and 40 ppm MoO3-NPs, resulting in nCB, CB10, and CB40 groups, respectively. This revealed a significant increase in BWC and total food intake (TFI) but a significant decrease in relative kidney weight in all the CB groups compared to the control group. In CB10 and CB40 groups ALT, LDH, TSH, FT3, and testosterone levels were significantly lower than the respective levels in the control group. We concluded that high doses of MoO3-NPs caused more side effects than low doses in both experiments.

Ameliorating effects of probiotics on alterations in iron homeostasis and inflammation in COVID-19.

INTRODUCTION: The coronavirus disease (COVID-19) is caused by the severe acute syndrome coronavirus-2 (SARS-COV-2) and still threatens human life. This pandemic is still causing increased mortality throughout the world. Many recent studies have been conducted to discover the pathophysiology of this virus. MATERIAL AND METHODS: However, in this narrative review, we attempted to summarize some of the alterations in physiological pathways that were evident in this viral invasion. Excessive inflammation that progresses to cytokine storm, changes in humoral and cell-mediated immunity, and observed alterations in iron metabolism are included in the pathogenesis of the virus. Iron homeostasis disturbances may persist for more than two months after the onset of COVID-19, which may lead to reduced iron bioavailability, hypoferremia, hyperferritinemia, impaired hemoglobin, and red blood cell synthesis. Furthermore, hypoferriemia may impair immune system function. Until now, the traditional treatments discovered are still being tried. RESULTS: However, using probiotics as an adjuvant was shown to have beneficial effects on both iron homeostasis and immunity in COVID-19. Herein, we discussed the possible mechanisms achieved by probiotics to ameliorate iron and immunity changes based on the available literature. CONCLUSION: We concluded that supplementing probiotics with conventional therapy may improve COVID-19 symptoms and outcomes. Taking into consideration the use of good quality probiotics and appropriate dosage, undesirable effects can be avoided.

Influence of GSTM1, T1 genes polymorphisms on oxidative stress and liver enzymes in rural and urban pesticides-exposed workers.

Several studies discussed the relationship between the toxicity of organophosphates (OPs) and carbamates pesticides and oxidative stress which affects human health. This study aimed to evaluate the effects of pesticides on the induction of oxidative stress and hepatotoxicity. It was also focused on glutathione-S-transferase gene polymorphism in the modulation of these effects. In addition, the role of the educational level of exposed workers was studied. Acetylcholinesterase (AChE), butyrylcholinesterase (BuChE), liver enzymes, malondialdehyde (MDA), reduced glutathione (GSH), superoxide dismutase (SOD), and glutathione S transferase (GST) were estimated at 100 pesticide-exposed workers (50 urban researchers (UE) and 50 rural sprayers (RE)), and 100 matched controls (50 urban controls (UC)and 50 rural controls (RC)). AChE and BuChE were decreased in RE and UE compared to RC. Aspartate aminotransferase (AST) and alkaline phosphatase (ALP) activity were elevated in UE and UC compared to the RE and RC. Alanine aminotransferase (ALT) was elevated in UE compared to RE. MDA in RE and UE showed elevation compared to RC. There was a significant reduction in the levels of GSH, GST, and GPx in UE compared to RE and RC. The most sensitive pesticide-induced hepatotoxicity group were exposed workers with the GSTT1 genotype. Within these workers, ALT and ALP were significantly correlated with MDA and inversely correlated with AChE and BuChE, while AST was inversely correlated with AChE and BuChE only in UE. Conclusion: GST gene polymorphisms appeared to have a significant role in workers' susceptibility to hepatotoxic effects due to occupational exposure to pesticides; GSTT1 was the most sensitive genotype.

Quercetin stimulates the non-amyloidogenic pathway via activation of ADAM10 and ADAM17 gene expression in aluminum chloride-induced Alzheimer's disease rat model.

AIMS: Alzheimer's disease (AD) is the most common progressive neurodegenerative disorder characterized by declined cognitive functions in the elderly. Quercetin (Q) is a potent flavonol that has neuroprotective effects on AD derangements. The present study aimed to evaluate the α-secretase stimulatory function of Q through activation of ADAM10 and ADAM17 gene expression in the aluminum chloride (AlCl3)-induced AD rat model. MAIN METHODS: After induction of AD in rats by oral administration of AlCl3 (50 mg/kg) for 28 days, the Q doses (25 and 50 mg/kg) were orally administered for 28 days. Rats performed the behavioral assessments during the last week of the treatment period. Hippocampi were harvested for assessments of the neurochemical and histopathological examinations and gene expression analysis. KEY FINDINGS: Administration of Q to AlCl3-induced AD rat model attenuated behavioral deficits, improved cholinergic and dopaminergic dysfunctions, and diminished insoluble amyloid ß (Aß) plaques aggregation in the hippocampus. These ameliorative effects of Q were associated with down-regulation of APP, BACE1, APH1, and PSEN1 and up-regulation of ADAM10 and ADAM17 gene expression levels in the hippocampus. SIGNIFICANCE: The present study suggests that Q might attenuate neurotransmission impairment, Aß aggregation in the hippocampus, and behavioral deficits in the AlCl3-induce AD rat model via up-regulating ADAM 10 and ADAM 17 (α-secretase) gene expression, leading to the inhibition of the amyloidogenic pathway. In support of the present finding, we suggest that ADAM10 and ADAM17 activation might be potential drug targets for AD to counteract the Aß aggregation and cognitive deterioration.

Dietary conjugated linoleic acid and medium-chain triglycerides for obesity management.

Obesity is considered a serious global health issue. Patients have been predisposed to comorbidities such as dyslipidemia, cardiovascular diseases, diabetes, cancers, and osteoarthritis. Certain fats in the diet have been linked with an increase in obesity, such as saturated and trans-fats. Meanwhile, some dietary fats such as conjugated linoleic acids (CLAs) and medium-chain triglycerides (MCTs) could potentially reduce energy intake. Various mechanisms for reducing weight by CLAs and MCTs, such as increased lipolysis, improved intestinal microbiota, up-regulating peroxisome proliferator-activated receptors (PPARs), increased the expression of uncoupling protein of respiratory chain-1 (UCP-1), and affected satiety hormones are included. These bioactive compounds, CLAs and MCTs, should be used in moderate concentrations to prevent harmful effects such as insulin resistance for CLAs and hypercholesterolemia for MCTs. However, several studies have proposed CLAs or MCTs as adjuvants to the protocol used to minimize bodyweight. Our objective is to summarize the different causes of obesity and to discuss the effects of CLAs or MCTs on body weight and fat deposition in obese animals or humans.

Neurotoxicity of organic solvents with emphasis on the role of iron.

BACKGROUND: Exposure to organic solvents (OS) adversely affects different body systems, the central and peripheral nervous systems being the most susceptible ones. OBJECTIVES: This study investigated the role of iron in association with some neurotransmitters for diagnosis of neurotoxicity of OS. METHODS: The study included 90 workers, 50 occupationally exposed to OS and 40 representing control group. Blood samples were collected from the included subjects for determination of serum iron, total iron binding capacity (TIBC), serotonin and gamma-aminobutyric acid (GABA). RESULTS: Revealed reduction in serotonin level and serum iron. However, the elevation in GABA and TIBC was observed. The duration of exposure was significantly correlated with iron and serotonin while it was positively correlated with GABA and TIBC. CONCLUSIONS: Elevated GABA and TIBC with decreased serotonin and serum iron can be used as early diagnostic measures to detect the neurotoxic effects of OS.

Evaluation of the effect of serum cystatin-C and ACE I/D and ACE G2350A polymorphisms on kidney function among hypertensive sewage workers.

Cadmium (Cd) as nephrotoxicant metal exerts its potent effect mainly on renal tubules disturbing its functions. A cross-sectional study was conducted on 55 sewage workers occupationally exposed to Cd and 50 control subjects. The study aimed to assess the effect of low-level Cd exposure on blood pressure and renal function in terms of serum cystatin-C levels. The associations between genetic polymorphisms of ACEI/D and ACE G2350A and hypertension and tubular injury among workers were studied. We analyzed blood and urine Cd concentration (U-Cd), serum cystatin-C, ACE I/D polymorphisms, and ACE G2350A, and blood pressure was measured. Results recorded a significant rise in serum and U-Cd and cystatin-C levels in sewage workers compared with controls. Significant distribution in genotype frequency of ACE I/D and ACE G2350A gene was detected. An association in DD genotype of ACE I/D with a rise in serum and U-Cd was observed in workers. In wild type genotype GG of ACE G2350A gene, a significant rise in serum cystatin-C levels and diastolic pressure was found while in heterozygote genotype GA significant rise in U-Cd levels was detected. Also, the association of AA genotype of ACE G2350A gene with a significant rise in serum and U-Cd and cystatin-C levels was shown among workers compared with control groups. Our findings indicated an association of ACE DD polymorphism in conjugation with GG genotype of ACE2 with hypertension and tubular injury in sewage workers.

Hepatotoxicity of aflatoxin B1 and its oxidative effects in wood dust Egyptian exposed workers.

The goal of the present study is to estimate the oxidative effects of AFB1 induced hepatotoxicity in furniture wood dust exposed workers. A cross-sectional comparative study was designed for comparing AFB1/albumin (AFB1/alb) levels and liver functions [alanine aminotransferase (ALT), aspartate aminotransferase (AST), and alkaline phosphatase (ALP)], malondialdehyde (MDA), glutathione peroxidase (GPx), catalase (CAT) and superoxide dismutase (SOD) in 88 furniture workers and 78 controls not occupationally exposed to wood dust. The AFB1/Alb, AST, ALT, MDA, and GPx were significantly higher; while, CAT significantly reduced in workers compared with controls. There was a significant correlation between AFB1/Alb and MDA level with the liver enzymes among both groups. CAT was inversely correlated with AFB1/Alb and the liver enzymes, and GPx was inversely correlated with AST in the workers. It was concluded that wood dust exposure is associated with raised serum levels of AFB1 and oxidative stress.

Assessment of YKL-40, lipid profile, antioxidant status, and some trace elements in benign and malignant breast proliferation.

Breast cancer is mainly the common form of cancer in women and is a leading cause of death worldwide associated with cancer. The objective of this study was to assess the possible association of lipid profiles (total cholesterol TC, low-density lipoprotein LDL, very-low-density lipoprotein VLDL, high-density lipoprotein HDL, non-HDL and triglyceride TG), Chitinase-3-Like Protein1 (YKL-40) and changes in the levels of certain trace elements (Cu, Mg, Fe, and Zn), antioxidant status (TAC) and nitric oxide (NO) in benign and breast cancer in Egyptian females population. For 56 females with a benign breast tumor, 58 females with breast cancer, besides 52 healthy controls, Serum lipid profile, YKL-40, TAC, NO, Cu, Fe, Zn, and Mg have been determined. Our results showed a significant difference in lipid profile and a significant increase in, YKL-40, NO, and iron in breast benign tumor and cancer patients compared to control one. Besides, there is a significant reduction in serum magnesium and TAC levels in the patients' group compared to the healthy group. There is also a significant correlation between serum YKL-40 level and TC, LDL-C, VLDL-C, non-HDL-C, and TG in the breast cancer group; although only YKL-40 and VLDL-C showed a significant positive correlation in benign tumor patients. It is recommended that non-HDL-cholesterol, TAC, and Mg be used as biomarkers for breast cancer and its progression.

Effects of zinc supplementation on oxidant/antioxidant and lipids status of pesticides sprayers.

Background Excess exposure to pesticides induces oxidative stress and causes alteration in the lipid profile Objectives The study aimed to evaluate the effects of Zinc (Zn) supplementation on the oxidant/antioxidant and lipid status in pesticide sprayers. Methods Forty pesticide sprayers were included in the study. Blood lipids, malondialdehyde (MDA), glutathione peroxidase (GPx), superoxide dismutase (SOD), and Zn were estimated; before and after Zn supplementation. Results Statistical analysis revealed that after Zn supplementation, total cholesterol (TC), triglycerides (TG), low density lipoprotein (LDL), very low density lipoprotein (VLDL), and MDA were significantly decreased. However, there was a significant increase in the high density lipoprotein (HDL), SOD, GPx, and Zn levels. After Zn supplementation, significant inverse correlations were detected between the Zn and the levels of MDA, TG, and VLDL, while positive correlation between Zn and the levels of HDL and TC. Conclusions Zn supplementation improves the oxidative/antioxidants and lipid status in pesticide sprayers.

Audiometric notch for the prediction of early occupational hearing loss and its association with the interleukin-1beta genotype.

OBJECTIVES: Noise-induced hearing loss (NIHL) is a frequent and irreversible industrial-health problem, the early diagnosis of which can prevent hearing deterioration, especially of speech frequencies. This study aimed to assess hearing impairment in workers occupationally exposed to noise. Audiometric notches and IL-1ß gene polymorphisms were evaluated. METHODS: The study included 98 workers employed in a textile factory. Pure-tone audiometric testing was conducted for all workers, using a manual pure-tone diagnostic audiometer, and the noise level was measured at four different work sites in a spinning section. IL-1ß gene polymorphism was determined using PCR-RFLP methods. RESULTS: Workers were exposed to a mean noise level of 105.5 dB. As many as 27.6% of them complained of tinnitus and the majority suffered from some degree of hearing loss in either ear, but none of them exceeded 60 dB. Audiometric notches were detected in either one or both ears. Only 28.6% of workers showed the absence of notches. The TT genotype of IL-1ß polymorphisms was dominant in 49% of the workers, whereas TC was predominant in 39.8% and CC in 11.2%. The CC genotype was associated with smoking (54.5%) and audiometric notches (100%). The IL-1ß genotype distribution showed no significant difference with or without tinnitus. CONCLUSION: This study showed an association between the CC genotype and smoking as well as audiometric notches in workers occupationally exposed to noise. Workers showing audiometric notches should be followed up regularly. Further studies are required to confirm the interrelationship amongst tinnitus, audiometric notches, and IL-1ß genotypes.

The effect of white kidney bean fertilized with nano-zinc on nutritional and biochemical aspects in rats.

This study aims to estimate the safety of white kidney bean (WKB) fertilized by zinc oxide nanoparticles (ZnO-NPs) via studying changes of liver and kidney function, lipid profile and histological examination for the liver and kidney tissue in rats fed on it. Twenty Four male albino rats were used in this study divided into four groups; the first fed balanced diet (control group), the second fed WKB treated with normal ZnO (nWKB), the third fed WKB treated with 20 ppm ZnO-NPs (tWKB-1), and the fourth fed WKB treated with 40 ppm ZnO-NPs (tWKB-2). The results revealed that WKB treated with ZnO-NPs reduced body weight, food efficiency ratio, relative liver weight, and relative spleen weight were increased as well as the most biochemical parameters exhibited non-significant changes as compared to control group. Meanwhile, tWKB-2 group demonstrated a decrease in alkaline phosphatase and aspartate transaminase activities as compared to nWKB group.

Dietary antioxidant for disease prevention corroborated by the Nrf2 pathway.

Dietary antioxidants are widely distributed in various types of our food. They are strongly associated with reduced risk of many chronic diseases such as atherosclerosis, cancer, and Alzheimer's diseases. They include vitamins such as vitamins A, E, C, and carotenoids. Also, some minerals like; zinc, manganese, copper, iron, and selenium are essential for the activity of antioxidant enzymes. Furthermore, dietary polyphenols and flavonoids are considered as potent antioxidant compounds. Vegetables, fruits, and edible herbs are the richest sources of such antioxidants. Antioxidants reduce oxidative stress, either directly by reducing reactive species or indirectly by enhancing the body antioxidant defense mechanisms in different ways. These may include upregulating gene expression of some antioxidant enzymes via a nuclear factor erythroid 2 related factor2 pathway. Administration of a mixture of antioxidants is beneficial since they act synergistically in various phases. The aims of this review are to summarize the different antioxidants from dietary sources and their role in the prevention of different diseases.

Impact of occupational cadmium exposure on bone in sewage workers.

Cadmium (Cd) is one of the environmental risk factors for bone loss. The present study included 40 sewage workers occupationally exposed to Cd. Forty nonexposed men were included as a control group. Current smokers represented 65% and 47.5% of the exposed and control groups, respectively. The study aimed to investigate the hazard of occupational Cd exposure on bone health. This was achieved through measuring serum and urinary Cd, and calcium (Ca), in addition to serum osteoprotegerin (OPG) and estrogen receptor-α gene. Results showed significant elevation in serum Cd, OPG, and urinary Ca levels in the exposed compared to the controls. Bony aches and joint pain were more prevalent among the exposed workers. Serum and urinary Cd increased in exposed smokers relative to control smokers. Also, serum OPG levels showed significant rise among exposed smoker and nonsmoker compared to control smoker and nonsmoker groups. Serum Cd level increased significantly in PP and pp genotypes in exposed workers compared to controls, while elevated levels of serum OPG was observed in PP and Pp genotypes in exposed workers relative to controls. Urinary Cd exhibited significant rise in both PP and pp genotypes in exposed workers, while Ca excretion was elevated in pp genotype only. The study reflected an association of genetic predisposition and Cd exposure in progression of osteoporosis. Further research is needed to explain the mechanisms of Cd impact on bone. The role of smoking is important and hence smoking cessation programs are essential for sewage workers.

Potential Renoprotective Effects of Rosemary and Thyme Against Gentamicin Toxicity in Rats.

Gentamicin (GM) is a drug used commonly against gram-negative bacteria. Its therapeutic use is mainly limited by its nephrotoxicity. This investigation was aimed at evaluating the nephroprotective effects of rosemary (RM; Rosmarinus officinalis) and thyme (TV; Thymus vulgaris) against GM toxicity. Rats were divided into four groups. Normal control group was treated intraperitoneally (i.p.) with saline; positive control group was administered GM 60 mg/kg/day i.p.; RM group was co-administered 8% RM aqueous extract, 10 mL/kg/day, orally with GM; and TV group was co-administered 8% TV aqueous extract orally, 10 mL/kg/day with GM. Both RM and TV groups extracted significantly ameliorated plasma kidney function biomarkers, and reduced malondialdhyde and glucose levels. Meanwhile, RM extract significantly modulated the electrolyte concentration and increased plasma insulin levels as compared with the GM group. However, the aqueous extract of RM showed more pronounced effects than TV extract. Our data were confirmed by histopathological examination and deoxyribonucleic acid (DNA) fragmentation analysis. Deleterious histopathological changes and increased DNA fragmentation induced by GM treatment were markedly controlled by the co-administration of RM and TV. Such renoprotective influence of RM and TV suggests their concurrent supplementation with GM therapy to limit GM toxicity.

Effect of Occupational Cadmium Exposure on Parathyroid Gland.

BACKGROUND: Cadmium (Cd) is used in many industries. High-level exposure is associated with severe kidney and bone damage. AIM: This study investigates the possible effect of occupational cadmium exposure on parathyroid gland and some minerals in workers. METHODS: Environmental air monitoring of cadmium was done. Serum and urine cadmium levels, kidney function, some minerals, and plasma parathormone were estimated in the studied groups. RESULTS: The exposed workers had significantly higher Cd concentration in serum and urine than controls. The mean levels of plasma parathyroid hormone, serum phosphorus and magnesium were significantly lower among the exposed group. However, the mean levels of serum creatinine and calcium were significantly higher in the same group when compared to referents. There was a significant positive correlation between Cd concentration in the serum and urine for the exposed group. The biological Cd exposure indices correlated positively with serum calcium and negatively with plasma PTH level. The prevalence of musculoskeletal complaints, bone ache, joint pain and muscle spasm were more prevalent among the exposed workers compared with the controls with odds ratio 4.316, 3.053 and 3.103 respectively. CONCLUSIONS: Occupational cadmium exposure has an adverse effect on PTH level and serum human minerals.

Comparative Hepatotoxicity of Aflatoxin B1 among Workers Exposed to Different Organic Dust with Emphasis on Polymorphism Role of Glutathione S-Transferase Gene.

AIM: The study aimed to investigate effects of organic dust exposure from different sources on aflatoxin B1-albumin adducts (AFB1/Alb), and role of glutathione S-transferase (GST) gene polymorphism in hepatotoxicity of (AFB1) among exposed workers. MATERIAL AND METHODS: Liver enzymes, AFB1/Alb, and GST polymorphism were estimated in 132 wheat flour dust and 87 woods sawmill workers, and 156 controls. RESULTS: Results revealed that AFB1/Alb and liver enzymes were significantly elevated in exposed workers compared to controls, and were significantly higher in sawmill workers compared to flour workers. AFB1/Alb in flour and sawmill workers with GSTT1 and GSTM1&GSTT1 null genotypes were significantly higher than controls, and in sawmill workers with GSTM1&GSTT1 null than flour workers. Liver enzymes (ALT and AST) in sawmill workers were significantly higher than flour workers and controls in all GST polymorphism; except in GSTT1 polymorphism, where these enzymes were significantly higher in the two exposed groups than controls. CONCLUSIONS: In conclusion, organic dust exposure may cause elevation in AFB1/Alb and liver enzymes of exposed workers, and GST gene polymorphism plays an important role in susceptibility to hepatic parenchymal cell injury; except in workers with GSTT1&GSTM1 null genotype, gene susceptibility seemed to have little role and the main role was for environmental exposures.

Hematological effect of benzene exposure with emphasis of muconic acid as a biomarker.

Human exposure to benzene in work environment is a global occupational health problem. It is established that benzene requires to be metabolized to induce its effects. Benzene has been associated with various hematotoxins and carcinogens. The aim of this study was to investigate the effect of benzene on complete blood picture, with emphasis of trans, trans-muconic acid (t,t-MA) as a biomarker of benzene in urine, considering the influence of cigarette smoke. A total of 81 workers (61 males and 20 females) have been occupationally exposed to benzene. In addition, 83 workers (55males and 28 females) were also recruited as a control group. Complete blood picture was analyzed and urinary t,t-MA was determined by liquid chromatography. In addition, creatinine in the urine samples was determined. Levels of blood elements (white blood cells, red blood cells and platelets) were decreased among exposed workers compared with the controls. The urinary level of t,t-MA/creatinine of the exposed workers was elevated especially in the smoking group compared to the controls. This study recommends that complete blood picture and t,t-MA are helpful biomarker tests that should be done to detect the early effects of benzene exposure.

Hepatoprotective, antioxidant, and ameliorative effects of ginger (Zingiber officinale Roscoe) and vitamin E in acetaminophen treated rats.

Ginger is a remedy known to possess a number of pharmacological properties. This study investigated efficacy of ginger pretreatment in alleviating acetaminophen-induced acute hepatotoxicity in rats. Rats were divided into six groups; negative control, acetaminophen (APAP) (600 mg/kg single intraperitoneal injection); vitamin E (75 mg/kg), ginger (100 mg/kg), vitamin E + APAP, and ginger + APAP. Administration of APAP elicited significant liver injury that was manifested by remarkable increase in plasma alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP), arginase activities, and total bilirubin concentration. Meanwhile, APAP significantly decreased plasma total proteins and albumin levels. APAP administration resulted in substantial increase in each of plasma triacylglycerols (TAGs), malondialdhyde (MDA) levels, and total antioxidant capacity (TAC). However, ginger or vitamin E treatment prior to APAP showed significant hepatoprotective effect by lowering the hepatic marker enzymes (AST, ALT, ALP, and arginase) and total bilirubin in plasma. In addition, they remarkably ameliorated the APAP-induced oxidative stress by inhibiting lipid peroxidation (MDA). Pretreatment by ginger or vitamin E significantly restored TAGs, and total protein levels. Histopathological examination of APAP treated rats showed alterations in normal hepatic histoarchitecture, with necrosis and vacuolization of cells. These alterations were substantially decreased by ginger or vitamin E. Our results demonstrated that ginger can prevent hepatic injuries, alleviating oxidative stress in a manner comparable to that of vitamin E. Combination therapy of ginger and APAP is recommended especially in cases with hepatic disorders or when high doses of APAP are required.

Proposed remedies for some developmental disorders.

Developmental disorders (DDs) are important leading cause of disability in developed countries and also in the United States. DDs are a group of individual conditions that result from abnormal nervous system development and cause altered function. They can begin at any time from prenatal to 22 years of age and the disability usually presents itself throughout a person's life time. Down syndrome, autism, neural tube defects, schizophrenia, cretinism, and attention-deficit hyperactivity disorder are among the most common DDs that currently plague numerous countries and have varying incidence rates. Their occurrence may be partially attributable to the lack of certain dietary nutrients. Notably, essential vitamins, minerals, and ω-3 fatty acids are often deficient in the general population of America and developed countries and are exceptionally deficient in patients suffering from mental disorders. Typically, most of these disorders are treated with prescription drugs, but many of these drugs cause unwanted side effects. Therefore, psychiatrists recommend alternative or complementary nutritional remedies to overcome the adverse effects of those drugs. Studies have shown that daily supplements of vital nutrients, such as that contain amino acids, often effectively reduce symptoms of the patients, because they are converted into neurotransmitters that alleviate depression and other mental disorders. The aim of this article is to discuss the role of dietary imbalances in the incidence of DD and to emphasize which dietary supplements can aid in the treatment of the above-mentioned DD.
