TL;DR: An attempt has been made to give an overview of certain Indian plants with their phytoconstituents and mechanism of action which have been studied for their antidiabetic activity.
Abstract: Diabetes and its different types is an age old disease for clinicians since centuries. Many aspects of Diabetes needs to be explored with respect to physiological actions of insulin and the various clinical features of this disease such as tissue complication , since this is life style disease , so proper treatment in relation to diet and anti diabetic agents is emphasized In fact, herbal treatment for diabetes is not new. Plants and plant extracts were used to combat the disease as early as 1550 B.C., with as many as 400 "prescribed" before the development earlier this century of effective medications to control diabetes. In this paper an attempt has been made to give an overview of certain Indian plants with their phytoconstituents and mechanism of action which have been studied for their antidiabetic activity. *Correspondence for Author

TL;DR: This paper will present a brief discussion of some well- and little-known herbs that may add to the optimization of antioxidant status and therefore offer added preventive values for overall health.
Abstract: Antioxidant-the word itself is magic. Using the antioxidant concept as a spearhead in proposed mechanisms for staving off so-called "free-radical" reactions, the rush is on to mine claims for the latest and most effective combination of free-radical scavenging compounds. We must acknowledge that such "radicals" have definitively been shown to damage all biochemical components such as DNA/RNA, carbohydrates, unsaturated lipids, proteins, and micronutrients such as carotenoids (alpha and beta carotene, lycopene), vitamins A, B6, B12, and folate. Defense strategies against such aggressive radical species include enzymes, antioxidants that occur naturally in the body (glutathione, uric acid, ubiquinol-10, and others) and radical scavenging nutrients, such as vitamins A, C, and E, and carotenoids. This paper will present a brief discussion of some well- and little-known herbs that may add to the optimization of antioxidant status and therefore offer added preventive values for overall health. It is important to state at the outset that antioxidants vary widely in their free-radical quenching effects and each may be individually attracted to specific cell sites. Further evidence of the specialized nature of the carotenoids is demonstrated by the appearance of two carotenoids in the macula region of the retina where beta-carotene is totally absent.

TL;DR: The biological activities of imidazole is reviewed during the past years to optimize solubility and bioavailability parameters of proposed poorly soluble lead molecules.
Abstract: Imidazoles have occupied a unique position in heterocyclic chemistry, and its derivatives have attracted considerable interests in recent years for their versatile properties in chemistry and pharmacology. Imidazole is nitrogen-containing heterocyclic ring which possesses biological and pharmaceutical importance. Thus, imidazole compounds have been an interesting source for researchers for more than a century. The imidazole ring is a constituent of several important natural products, including purine, histamine, histidine, and nucleic acid. Being a polar and ionisable aromatic compound, it improves pharmacokinetic characteristics of lead molecules and thus is used as a remedy to optimize solubility and bioavailability parameters of proposed poorly soluble lead molecules. There are several methods used for the synthesis of imidazole-containing compounds, and also their various structure reactions offer enormous scope in the field of medicinal chemistry. The imidazole derivatives possess extensive spectrum of biological activities such as antibacterial, anticancer, antitubercular, antifungal, analgesic, and anti-HIV activities. This paper aims to review the biological activities of imidazole during the past years.

TL;DR: UFG posses an antidiabetic, antioxidant and antihyperlipidemic effect on the STZ induced diabetic rat and could be the better choice to cure the diabetes.
Abstract: Aegle marmelos (L.) Corr. (Rutaceae), commonly known as bael, is used to treat fevers, abdomen pain, palpitation of the heart, urinary troubles, melancholia, anorexia, dyspepsia, diabetes and diarrhea in Indian traditional systems of medicine. The object of the present study was to evaluate the antidiabetic, antihyperlipidemic and antioxidant oxidative stress of umbelliferone β-D-galactopyranoside (UFG) from stem bark of Aegle marmelos Correa. in STZ (streptozotocin) induced diabetic rat. Diabetes was induced in rat by single intraperitoneal injection of STZ (60 mg/kg). The rat was divided into the following groups; I – normal control, II – diabetic control, III – UFG (10 mg/kg), IV – UFG (20 mg/kg), V – UFG (40 mg/kg), VI – Glibenclamide (10 mg/kg, p.o., once a daily dose). Diabetes was measured by change the level blood glucose, plasma insulin and the oxidative stress were assessed in the liver by estimation of the level of antioxidant markers i.e. superoxide dismutase (SOD), glutathione peroxidase (GPx), catalase (CAT) and Malondialdehyde (MDA) and antihyperlipidemic effect was measured by estimation of total cholesterol, triglycerides, LDL (low density lipoprotein) cholesterol, HDL (high density lipoprotein) cholesterol, VLDL (very low density lipoprotein) cholesterol. However in a study, the increased body weight was observed and utilization of glucose was in the oral glucose tolerance test. Daily oral administration of different dose of UFG for 28 days showed significantly (P < 0.001) decreased in fasting blood glucose level and improve plasma insulin level as compared to the diabetic control group. Also it significantly (P < 0.001) decreased the level of glycated hemoglobin, glucose-6-phosphatase, fructose-1-6-biphosphate and increased the level of hexokinase. UFG treatment decreased liver MDA and increased the level of SOD, GPx and CAT. UFG treatment of lipids it’s increased the level of cholesterol, triglycerides, VLDL, LDL cholesterol and decreased the level of HDL cholesterol. Histologically, inflammatory cell in blood vessels, intercalated disc, fat degeneration and focal necrosis observed in diabetic rat organ but was less obvious in UFG treated groups. The mechanism of action of UFG may be due to the increased level of pancreatic insulin secretion and effect on the antioxidant marker. UFG posses an antidiabetic, antioxidant and antihyperlipidemic effect on the STZ induced diabetic rat. Hence it could be the better choice to cure the diabetes.

TL;DR: There is, I think, something ethereal about i —the square root of minus one, which seems an odd beast at that time—an intruder hovering on the edge of reality.
Abstract: There is, I think, something ethereal about i —the square root of minus one. I remember first hearing about it at school. It seemed an odd beast at that time—an intruder hovering on the edge of reality. Usually familiarity dulls this sense of the bizarre, but in the case of i it was the reverse: over the years the sense of its surreal nature intensified. It seemed that it was impossible to write mathematics that described the real world in …

TL;DR: It is suggested that if assessment of overdoses were left to house doctors there would be an increase in admissions to psychiatric units, outpatients, and referrals to social services, but for house doctors to assess overdoses would provide no economy for the psychiatric or social services.
Abstract: admission. This proportion could already be greater in some parts of the country and may increase if referrals of cases of self-poisoning increase faster than the facilities for their assessment and management. The provision of social work and psychiatric expertise in casualty departments may be one means of preventing unnecessary medical admissions without risk to the patients. Dr Blake's and Dr Bramble's figures do not demonstrate, however, that any advantage would attach to medical teams taking over assessment from psychiatrists except that, by implication, assessments would be completed sooner by staff working on the ward full time. What the figures actually suggest is that if assessment of overdoses were left to house doctors there would be an increase in admissions to psychiatric units (by 19°U), outpatients (by 5O°'), and referrals to social services (by 140o). So for house doctors to assess overdoses would provide no economy for the psychiatric or social services. The study does not tell us what the consequences would have been for the six patients who the psychiatrists would have admitted but to whom the house doctors would have offered outpatient appointments.
