Abstract
Diabetes mellitus (DM) is metabolism related problems that share the phenotype of hyperglycemia, which is triggered by a complicated interaction of hereditary and environmental elements. It is the main reason for end-stage renal disease (ESRD), amputations of the traumatic lower extremity, and grown-up visual impairment. It additionally inclines to neurodegenerative and cardiovascular sicknesses. With an expanding rate around the world, DM may be the main motive of morbidity and mortality within the foreseeable future. The objective of treatment for DM is to inhibit mortality and difficulties through normalizing blood glucose stage. Genistein, a naturally available soy isoflavone, is accounted for to have various medical advantages credited to numerous natural capacities. In the course of recent years, various examinations have shown that genistein has hostile to diabetic impacts, specifically, direct consequences for β-cell expansion, glucose-triggered insulin discharge, and safety towards apoptosis, unbiased of its functions as an estrogen receptor agonist, cancer prevention agent, or tyrosine kinase inhibitor. The present evaluation emphases on the promising molecular and biochemical paths associated with DM complications and, specifically, the multi-target method of genistein in diminishing diabetic neuropathy, nephropathy, and retinopathy.

Abstract
OBJECTIVES Altered amyloid metabolism and mitochondrial dysfunction play key roles in the development of Alzheimer's disease (AD). We asked whether an association exists between disturbed platelet mitochondrial respiration and the plasma concentrations of Aβ40 and Aβ42 in patients with AD. DESIGN AND METHODS Plasma Aβ40 and Aβ42 concentrations and mitochondrial respiration in intact and permeabilized platelets were measured in 50 patients with AD, 15 patients with vascular dementia and 25 control subjects. A pilot longitudinal study was performed to monitor the progression of AD in a subgroup 11 patients with AD. RESULTS The mean Aβ40, Aβ42 and Aβ42/Aβ40 levels were not significantly altered in patients with AD compared with controls. The mitochondrial respiratory rate in intact platelets was significantly reduced in patients with AD compared to controls, particularly the basal respiratory rate, maximum respiratory capacity, and respiratory reserve; however, the flux control ratio for basal respiration was increased. A correlation between the plasma Aβ42 concentration and mitochondrial respiration in both intact and permeabilized platelets differs in controls and patients with AD. CONCLUSIONS Based on our data, (1) mitochondrial respiration in intact platelets, but not the Aβ level itself, may be included in a panel of biomarkers for AD; (2) dysfunctional mitochondrial respiration in platelets is not explained by changes in plasma Aβ concentrations; and (3) the association between mitochondrial respiration in platelets and plasma Aβ levels differs in patients with AD and controls. The results supported the hypothesis that mitochondrial dysfunction is the primary factor contributing to the development of AD.

Abstract
The isoflavone, genistein, present in soybean is being actively investigated for its potential beneficial effect against Alzheimer's disease. Our data, however, show that in SHSY5Y cells genistein causes increased expression (mRNA and protein) of amyloid precursor protein (APP), increased mRNA expression and activity of β-secretase and diminished level of insulin degrading enzyme (IDE) which also degrades amyloid beta peptide. These effects of genistein lead to enhanced accumulation of amyloid beta peptide (Aβ42) in SHSY5Y cells. The results do not support the view that genistein could be a putative drug against AD and instead strengthen the epidemiological study which implies that genistein content of soybean food product (Tofu) leads to cognitive impairment.

Abstract
Platelet mitochondrial MAO-A activity of male albino rats (Wistar strain) was significantly inhibited with an inhibition of its only V max during aging. This age-induced inhibition of platelet MAO-A activity became reversed following the application of higher dosages (2.0-2.5 μg/kg/day, i.t. for 21 consecutive days) of carnosine. Though carnosine at lower dosage (0.5 μg/kg/day, i.t. for 21 consecutive days) was ineffective to platelet mitochondrial MAO-A activity in both young and aged rats, at higher dosages (2.0-2.5 μg/kg/day, i.t. for 21 consecutive days) under similar condition this enzyme activity was significantly enhanced. Carnosine at 1.0 μg/kg/day, i.t. for 21 consecutive days significantly enhanced MAO-A activity only in aged (18 and 24 months) rats. These results suggest that carnosine withdraws the aging-induced inhibition of mammalian blood platelet MAO-A activity and restores its activity towards that (MAO-A activity) observed in young mammalian blood platelets.

Abstract
Using ovariectomized middle-aged rats to mimic the post-menopausal pathophysiological changes in women, we have previously demonstrated that estrogen withdrawal and age-related decrease in the functional reserve of mitochondria might co-operate to induce persistent mitochondrial dysfunction, which may be critical in inducing degenerative processes in the brain later in post-menopausal women. The standardized Ginkgo biloba extract EGb761 has long been considered a natural antioxidant. More recently it has also proposed to have direct protective effects on the mitochondria. In this work, effects of EGb761 on mitochondrial function in platelets and hippocampi of ovariectomized and sham-operated rats were investigated. It was found that EGb761 protected against the decrease of cytochrome c oxidase (COX) activity, mitochondrial ATP (adenosine-5'-triphosphate) content and mitochondrial glutathione (GSH) content in both platelets and hippocampi of ovariectomized rats, suggesting its peripheral and central effects against estrogen withdrawal-induced degeneration. In contrast, in sham-operated rats, EGb761 increased mitochondrial GSH content in platelets but failed to show similar effect on hippocampi, suggesting that EGb761 may help to enhance the functional reserve of mitochondria, but this effect was limited to the outside of the central nervous system. EGb761 displayed similar effects on platelets and hippocampi of ovariectomized rats but showed differential effects on platelets and hippocampi of sham-operated rats, possibly because estrogen withdrawal induced an increase of blood brain barrier (BBB) permeability. Therefore, while EGb761's effect may be limited to the outside of the nervous system under normal physiological conditions, EGb761 may be a potential protective agent against central neurodegeneration in post-menopausal women.

Abstract
Mitochondrial dysfunction may play an important role in the pathogenesis of ageing and age-neurodegenerative diseases such as Alzheimer's disease (AD). Platelet mitochondrial membrane potential (reflected by measurement of JC-1 fluorescence ratio) and adenosine 5'-triphosphate (ATP) contents of 24 moderate probable AD patients, 20 age-matched control subjects and 20 young control subjects were measured. Also, a beta-amyloid peptide (Abeta)-induced damage model of platelets was established. After the addition of Abeta, platelet JC-1 fluorescence ratio and ATP content of platelets were measured in 16 AD patients, 20 aged and 20 young control subjects. Young control subjects had higher JC-1 fluorescence ratio than both AD patients and aged control subjects. No significant differences in platelet ATP contents were found among AD patients, aged and young control subjects. After the addition of Abeta, platelet JC-1 fluorescence ratio and ATP content of aged and young control subjects lowered markedly, but no obvious decrease of platelet JC-1 fluorescence ratio of AD patients was found compared with those of aged and young control subjects. Decrease of platelet JC-1 fluorescence ratio of aged control subjects was lower than that of young control subjects following the addition of Abeta. These results indicated that mitochondrial dysfunction may occur during ageing and platelet mitochondria of AD patients and aged subjects showed a tolerance to Abeta-induced damage. Therefore, blood platelets might serve as a biomarker for detection of mitochondrial function and age-related disease.
