A study on 300 adults diagnosed with T2DM selected by purposive random sampling was conducted at the diabetic clinic run at every weekend at the Health Center of Jiwaji University Gwalior. The study assessed the effect of nutritional counseling on food consumption, nutrient intake and dietary knowledge. The subjects were divided into two groups. Control group (Group-I 148 diabetic subjects) and the intervention group (Group-II 151 diabetic subjects). Food consumed and nutrient intake was recorded using the 24-hour recall method and dietary knowledge was assessed through a questionnaire. Slight change in food consumption and signicant increase in (p

The Mediterranean diet is appraised as the premier dietary regimen, and its espousal is correlated with the prevention of degenerative diseases and extended longevity. The consumption of olive oil stands out as the most peculiar feature of the Mediterranean diet. Olive oil rich in various bioactive compounds like oleanolic acid, oleuropein, oleocanthal, and hydroxytyrosol is known for its antiinflammatory as well as cardioprotective property. Recently in silico studies have indicated that phytochemicals present in olive oil are a potential candidate to act against SARS-CoV-2. Although there are many extensive studies on olive oil and its phytochemical composition, however, some lacunas persist in understanding how the phytochemical composition of olive oil is dependent on upstream processing. The signaling pathways regulated by olive oil in the restriction of various diseases are also not clear. For answering these queries, a detailed search of research and review articles published between 1990 to 2019 were reviewed. Olive oil consumption was found to be advantageous for various chronic non-communicable diseases. Olive oil’s constituents are having potent anti-inflammatory activities and thus restrict the progression of various inflammation-linked diseases ranging from arthritis to cancer. But it is also notable that the amount and nature of the phytochemical composition of household olive oil are regulated by its upstream processing, and the physicochemical properties of this oil can give a hint regarding the manufacturing method as well as its therapeutic effect. Moreover, daily uptake of olive oil should be monitored as excessive intake can cause body weight gain and a change in the basal metabolic index. So, it can be concluded that the olive oil consumption is beneficial for human health, and particularly for the prevention of cardiovascular diseases, breast cancer, and inflammation. The simple way of processing olive oil is to maintain the polyphenol constituents, whichprovide the protection against noncommunicable diseases and SARS-CoV-2.

Olive (Olea europaea L.) leaf extract (OLE) have shown therapeutic activity against different types of cancer. However, it is less known that olive leaf extract has anti myeloma activity. The in vitro cytotoxic activity of OLE was evaluated against mouse metastatic melanoma B16F10 cell lines. The extracts were analyzed for their antioxidant activity by DPPH radical scavenging activity and the presence of bioactive compounds by liquid chromatography-electrospray ionization-tandem mass spectrometry respectively. The aqueous OLE induced apoptosis of B16F10 cells through ERK 1/2 and p53 mediated pathway. The metabolic profiling of OLE showed 23 metabolites notably oleuropein aglycone, apigenin, luteolin, tyrosol, oleuropein and hydroxytyrosol. Oleuropein present in OLE may be responsible for disrupting the activation of ERK1/2 receptor in melanoma B16F10 cell lines. These findings pave path for further investigations of the structure and function at the molecular level to establish the anticancer activity of oleuropein in melanoma skin cancer.

Tetracycline is an established antibiotic and is targets to Wolbachia endosymbiont present within the filarial worms. Antibiotic treatment of filarial nematodes results in sterility and inhibits larval development and adult worm viability; this is due to effect on the Wolbachia. In the present study in vitro and in vivo anti-filarial effect of different concentration of tetracycline/ doxycycline was determined. In vitro results indicated that 50 µg/ml and 100 µg/ml tetracycline concentrations affects the motility in both microfilariae and adult worms of B. malayi. The loss of motility was efficiently higher in female adult worms than male adult worms, could be attributed to the differences in Wolbachia load of the filarial worms. 14 (10 Male and 4 female) microfilaraemic subjects were treated with doxycycline @ 200mg/day for 30 days to study the in vivo filaricidal effect. In which the mean mf counts were gradually decreased after doxycycline treatment in both male and female subjects upto 6 months. The findings suggest that tetracycline/ doxycycline treatment can eliminate or reduce the mf load due to targeting Wolbachia endosymbiont therefore provide good tool for treatment and to hamper the transmission of filariasis from one host to another.

Background: In Indian Medicine System, Arhar honey is believed as one of the valuable medicinal foods. Honey is being used since ancient times owing to its functional properties and nutritive value. Aims: We aimed to evaluate the effect of honey supplementation on fasting blood glucose (FBG) level and lipid profile of the subjects with impaired glucose tolerance (IGT) and healthy subjects. Methods: The selection of subjects was done through oral glucose tolerance test (World Health Organization/Food and Agriculture Organization, 1998). On the basis of blood glucose level, 28 subjects were selected by purposive random sampling and were divided into two groups. Group I included normal healthy subjects having FBG in the range of 70–100 mg/dl (n = 14), and Group II was comprised of subjects having FBG level between 100 and 125 mg/dl falling in the category of IGT (n = 14). 70 g honey was administered to subjects in both the groups on an empty stomach for 60 days and its effect on body weight, body mass index (BMI), blood pressure, FBG, glycated hemoglobin (HbA1c), and lipid profile was observed. Results: Honey administration lowered blood glucose levels and lipid levels in subjects with IGT and normal healthy subjects. Other benefits of honey administration include an increase in high-density lipoprotein cholesterol levels and a reduction in BMI. Conclusion: Consumption of honey has shown a reduction in body weight, BMI, FBG, HbA1c, and improvement in lipid profile in IGT subjects.

Aim of the present study is to estimate glycemic carbohydrates and develop data base on glycemic index and glycemic load (GI and GL) of commonly consumed cereals and legumes by using Food and Agriculture Organization (FAO) or World Health Organization (WHO) methods. The results of glycemic carbohydrates in rice was 79.22 %, wheat 63.26 % and pulses in the range from 51.24 % (green gram) to 56.22 %, (chana dhal), mixed dhal 40.09 %, wheat + chana dhal (60:40) 49.94 %, wheat + chana dhal + barley (40:30:30) was 46.89 %, respectively. The results of GI and GL of rice were the highest (GI–78.23, GL–49.38), followed by wheat chapatti (GI–65.66, GL–32.83). The pulses tested were showing lower values ranging from (GI–37.95 to 43.01 and GL–18.97 to 21.50), mixed dhal (GI–43.64, GL–21.82), wheat + chana dhal (60: 40) (GI–32.37, GL–16.18), wheat + chana dhal + barley (40:30:30) GI–39.27, GL–19.63, respectively. The results of the study indicated that pulses have low glycemic indices and glycemic loads, hence, could be safely used in the diet of diabetic patients.

Background The aim of this study is to determine the prevalence of Metabolic syndrome (MetS) in the people of Gwalior. Three criteria viz., National Cholesterol Education Program Adult Treatment Panel III (NCEP ATP III) criteria, International Diabetes Federation (IDF) criteria and Harmonized criteria for MetS were employed to assess the prevalence of metabolic syndrome in this region, their concordance with respect to this population was recorded. Methods The cross-sectional study involved the people, who had attended the Diabetes clinic at the Centre for Translational Research, Jiwaji University during 2015-2017. A total of 1190 participants within the age group of 20–79 years of either gender were included in the study. Anthropometric parameters, blood pressure, blood glucose and lipid profile of all subjects were assessed. Student's ‘t’ test, Kappa statistics and Binary logistic regression model were used to analyze the data. Results The percentage of prevalent MetS was found to be 72.7, 50.2 and 53.9 following Harmonized criteria, NCEP ATPIII and IDF criteria respectively. The prevalence was found to be maximum in centrally obese female population, aged between 51 and 60 years with the presence of hyperglycemia and reduced HDL– C. Harmonized and IDF criteria showed good agreement (κ 0.85). Regression analysis showed that, high body mass index, hypertension and dyslipedimia were the most critical predictive risk factors of MetS. Conclusions Maximum prevalence of MetS was recorded when the Harmonized criteria was followed. A good agreement was observed between Harmonized vs. IDF criteria. MetS if detected early especially in apparently healthy subjects; paves way for preventive measures to be designed in order to avert the incidence of diabetes and other risks related to cardio vascular disease.

Aim The present study was undertaken to develop a Curcumin nanoparticle system with chitosan as a hydrophilic carrier. In addition, the anti-diabetic potential of curcumin loaded chitosan nanoparticles were assessed in comparison to those of free curcumin by examining the anti-hyperglycemic efficacy using in vitro assays. Methods Curcumin loaded chitosan nanoparticles were prepared and characterized for particle size by transmission electron microscopy, FT-IR, differential scanning calorimetry and therapeutic effects of curcumin loaded chitosan nanoparticles were evaluated by measuring the level of GLUT-4 present at the plasma membrane in L6myc myotubes followed by western blotting. Additionally, anti-inflammatory potential of curcumin loaded chitosan nanoparticles were assessed by enzyme immunoassay using appropriate ELISA kits. Key findings Transmission electron microscopy revealed an average nanocurcumin particle size of 74 nm. Under in vitro conditions, treatment with chitosan-nanocurcumin (CS-NC) caused a substantial increase in the GLUT-4 translocation to the cell surface in L6 skeletal muscle cells and the effect was associated with increased phosphorylation of AKT (Ser-473) and its downstream target GSK-3β (Ser-9). Significance The therapeutic potential of nanocurcumin is prominent than that of curcumin alone. Nanocurcumin could improve the solubility of curcumin and may prolong its retention in the systemic circulation.

The study investigates the effects of aqueous extract of Bougainvillea spectabilis leaves on blood glucose, glycosylated hemoglobin, lipid profile, oxidative stress, and on DNA damage, if any, as well as on liver and kidney functions in streptozotocin-induced diabetes in Wistar rats. Daily administration of the aqueous extract of B spectabilis leaves for 28 days resulted in significant reduction in hyperglycemia and hyperlipidemia as evident from restoration of relevant biochemical markers following extract administration. The extract also exhibited significant antioxidant activity as evidenced from the enzymatic and nonenzymatic responses and DNA damage markers. The extract restored kidney and liver functions to normal and proved to be nontoxic. A marked improvement in the histological changes of tissues was also observed. The present study documented antihyperglycemic, antihyperlipidemic, and antioxidative potentials of the aqueous extract of B spectabilis leaves without any toxicity in streptozotocin-treated Wistar rats.

Nature’s silicon marvel, the diatoms have lately astounded the scientific community with its intricate designs and lasting durability. Diatoms are a major group of phytoplanktons involved in the biogeochemical cycling of silica and are virtually inherent in every environment ranging from water to ice to soil. The usage of diatoms has proved prudently cost effective and its handling neither requires costly materials nor sophisticated instruments. Diatoms can easily be acquired from the environment, their culture requires ambient condition and does not involve any costly media or expensive instruments, besides, and they can be transported in small quantities and proliferated to a desirable confluence from that scratch, thus are excellent cost effective industrial raw material. Naturally occurring diatom frustules are a source of nanomaterials. Their silica bio-shells have raised curiosity among nanotechnologists who hope that diatoms will facilitate tailoring minuscule structures which are beyond the capabilities of material scientists. Additionally, there is a colossal diversity in the dimensions of diatoms as the frustule shape differs from species to species; this provides a scope for the choice of a particular species of diatom to be tailored to an exacting requisite, thus paving the way to create desired three dimensional nanocomposites. The present article explores the use of diatoms in various arenas of science, may it be in nanotechnology, biotechnology, environmental science, biophysics or biochemistry and summarizes facets of diatom biology under one umbrella. Special emphasis has been given to biosilicification, biomineralization and use of diatoms as nanomaterial’s, drug delivery vehicles, optical and immune-biosensors, filters, immunodiagnostics, aquaculture feeds, lab-on-a-chip, metabolites, and biofuels.

Hepatotoxicity associated with isoniazid and rifampicin is one of the major impediments in antituberculosis therapy. The present study explored the prophylactic and therapeutic efficacies of Spirulina maxima in isoniazid and rifampicin induced hepatic damage in a rat model. Hepatic damage induced in Wistar rats by isoniazid and rifampicin resulted in significant alterations in biomarkers of liver function, namely, bilirubin, aspartate transaminase, alanine transaminase, alkaline phosphatase, and oxidative stress markers such as superoxide dismutase, catalase, glutathione, and thiobarbituric acid reactive substances. Co-administration of Spirulina maxima along with antituberculosis drugs protected liver from hepatotoxicity due to isoniazid and rifampicin. Administration of Spirulina maxima consecutively for 2 weeks to hepatodamaged animals resulted in restoration of hepatic function as evident from normalization of serum markers of liver function. Thus, the present study revealed remarkable prophylactic and therapeutic potential of Spirulina maxima. Co-administration of Spirulina maxima and antituberculosis drugs is advantageous as it provides extra nutritional benefit.

The study validated the antidyslipidemic, antioxidant, and antihyperglycemic effects of Lagenaria siceraria fruit extract in human subjects with dyslipidemia along with subjects of normal health. A total of 200 mL of freshly prepared Lagenaria siceraria fruit extract was administered daily on empty stomach for 90 days. Significant reductions ( P < .01) were found in triglycerides and total cholesterol levels in blood. Cardiac risk ratio, atherogenic coefficient, and atherogenicity index of plasma were also improved. Appreciable reductions in body mass index ( P < .01) and blood pressure (systolic P < .01, diastolic P < .05) along with a significant reduction ( P < .05) in fasting blood glucose levels were also observed in these subjects. Lagenaria siceraria fruit extract exhibited significant antioxidant activity in dyslipidemic subjects as evident from elevations in SOD ( P < .05) and GSH levels ( P < .01) with marked improvement in catalase ( P < .01) and TBARS levels ( P < .05). Phytochemical screening confirmed the presence of saponins, glycosides, flavonoids, terpenoids, and phenolic compounds. Lagenaria siceraria fruit extract serves as dietary adjunct in treatment of human dyslipidemia and cardiovascular disease.

Aim: This study evaluated the prevalence of prediabetes and type 2 diabetes mellitus in the Gwalior-Chambal region of India. Methods: A cross-sectional house-to-house survey was conducted on a population of 7608 subjects, aged between 20 and 79 years for fasting blood glucose level in finger-prick blood. Participants were stratified based on blood glucose levels, gender, age, family history, etc. to assess their impact. Result: The prevalence of type 2 diabetes and prediabetes in the Gwalior-Chambal region was found to be 11.4% and 5.7%, respectively. The prevalence of diabetes was significantly higher in the urban population (12.7%) while that of prediabetes was higher in the rural population (7.9%). Male subjects recorded a higher prevalence of prediabetes (8.2%, OR 1.54 in rural, 5.1%, OR 1.26 in urban) as well as diabetes (rural 9.2%, OR 3.15, urban 16.5%, OR 1.57). Both prediabetes and diabetes were recorded as being higher in those subjects leading a sedentary lifestyle and in the aged population. The prevalence of hyperglycemia was much higher in those with a family history of type 2 diabetes (30.6% in rural, 21.5% in urban). Almost half of the diabetics in the rural population were diagnosed for the first time. The multivariate regression analysis identified male gender, increasing age of 30 years and above, and positive family history as significant risk factors for diabetes whereas age of 40 to 79 and less physical activity were significant risk factors for prediabetes. Conclusion: Family history of diabetes, and sedentary lifestyle appeared as key factors promoting prediabetes and diabetes in the Gwalior-Chambal region. A lack of awareness appeared as one of the major causes of the high prevalence in the rural region.

Patients with diabetes mellitus have a higher risk of cardiovascular disease. Therefore, a reduction in all cardiovascular risks such as dyslipidemia, hypertension and being over-weight is advisable. Plants or their extracts such as Lagenaria siceraria (Bottle gourd) may have a potential therapeutic role in the treatment of diabetes. The aim of this study was to evaluate the neutraceutical potential of bottle gourd juice in the management of human diabetes and associated dyslipidemia. The study involved the administration of freshly prepared bottle gourd juice (200 ml) to 100 human participants (diabetic patients n = 50; healthy volunteers n = 50) on an empty stomach for 90 consecutive days. Biochemical markers of carbohydrate and lipid metabolism plus kidney and liver functions were monitored at monthly intervals during the course of bottle gourd juice administration. A notable reduction in blood glucose levels plus a significant reduction in total cholesterol (17.8%), serum triglycerides (16–22%), LDL-c (22.2%) and a considerable decrease in VLDL-c was observed in diabetic subjects on juice therapy. Anthropometric evaluation remained more or less unchanged. Bottle gourd juice administration contributed to significant elevations in superoxide dismutase and catalase activities in both diabetic (40.5%) as well as normal healthy subjects. An appreciable improvement in GSH levels (9% elevation) of diabetic subjects ( P L. siceraria juice may be used as an alternative and adjunctive treatment in disorders associated with carbohydrate and lipid metabolism.

A protocol was developed for multiple shoot induction in a climber with highly medicinal and nutritional values i.e. Momordica balsamina (Cucurbitaceae). Effects of various factors on micropropagation were also studied. Addition of BAP at 1.0 mg/l in MS medium stimulated proliferation of shoots with 6–8 coefficients from the axillary buds. Low concentration of activated charcoal (0.2 %) promoted shoot elongation and reduced callus formation. The combination of 1.0 mg/l BAP and 1.0 mg/l KN promoted shoot elongation and proliferation. NAA proved to be more effective in inducing higher number of roots per shoot than IBA. The plantlets raised in vitro were acclimatized in green house and successfully transplanted to natural condition with 85 % survival. The present investigation showed that direct regeneration of M. balsamina offer a good opportunity to use micropropagation technique as a complementary tool for breeding and other applications.

The potential of this macrofungus is unquestionable in the most important areas of applied biotechnology.

Anopheline mosquitoes are vectors of human malaria and hence they are of greatest concern. Around 40% of the world's population resides in malaria affected areas. Malaria affects poor communities and causes enormous economic losses. The deadly disease annually causes clinical illness in 400-600 million people and kills 2-3 millions annually (WHO 2008). Faunistic survey was conducted in Fingeswar block in Raipur district of Chhattisgarh state of India during January 2003 to March 2004 to asses the prevalence of different species of mosquitoes and their seasonal variations. Indoor resting mosquitoes were collected from selected houses in 5 villages using aspirator tube and torch light in the morning between 06:00-08:00. Adult mosquitoes were identifi ed using standard morphological and pictorial keys following Rao (1984), Das et al. (1991) and Reuben et al. (1994) and assessed as person hour density. A total of 13,248 mosquitoes were collected during the study period. Nine species of mosquitoes comprising of 4 genera with 5 Anopheles, two Culex and one each Armigeres and Aedes were recorded. The malaria vectors constituted 14.09% of the total mosquito collections. Anopheles subpictus (25.81%) showed the dominance followed by A. annularis (8.68%), A. barbirostris (6.76%), A. culicifacies (5.41%) and A. pallidus (4.11%). The other genus recorded included Culex quinquefasciatus (38.38%), C. vishnui (3.32%), Armigeres subalbatus (6.92%) and Aedes albopictus (0.29%). The density of all the species were high in months of August, September and October, decreased in month of May and June 2003. There was a signifi cant (p < 0.01) positive correlation between temperature and density of A. culicifacies and A. annularis. The seasonal distribution pattern of A. culicifacies (primary) and A. annularis (secondary) malaria vectors along with other mosquito species was studied which is an important component of epidemiological study of malaria. This information will help in formulating a baseline structure for control program in the study region.

In present study, we investigated hypoglycemic and antihyperglycemic potential of five extracts (water, ethanol, methanol, hexane, and chloroform) of four plants (i.e., seeds of Eugenia jambolana, fruits of Momordica charantia, leaves of Gymnema sylvestre, and seeds of Trigonella foenum graecum) alone and/or in combination with glimepiride in rats. Ethanol extract of E. jambolana, water extract of M. charantia, ethanol extract of G. sylvestre, and water extract of T. graecum exhibited highest hypoglycemic and antihyperglycemic activity (most active) in rats among all the extracts, while hexane extracts exhibited least activities. Most active extracts were further studied to dose-dependent (200, 100, and 50 mg/kg body weight (bw)) hypoglycemic and antihyperglycemic effects alone and in combination with glimepiride (20, 10, and 5 mg/kg bw). The combination of most active extracts (200 mg/kg bw) and lower dose of glimepiride (5 mg/kg bw) showed safer and potent hypoglycemic as well as antihyperglycemic activities without creating severe hypoglycemia in normal rats, while higher doses (200 mg/kg bw of most active extracts, and 10 and 20 mg/kg bw of glimepiride) were generated lethal hypoglycemia in normal rats. From this study, it may be concluded that the ethanol extract of E. jambolana seeds, water extract of M. charantia fruits, ethanol extract of G. sylvestre leaves, and water extract of T. graecum seeds have higher hypoglycemic and antihyperglycemic potential and may use as complementary medicine to treat the diabetic population by significantly reducing dose of standard drugs.

In the present study, the polyherbal preparation diabegon, containing 18 plant extracts with hypoglycemic activity, was evaluated for its preventive effect during progression of type 2 diabetes in high-fructose-diet–fed rats. Oral administration of diabegon (100 mg/kg body weight) delayed development of glucose intolerance for 4 weeks in comparison with the diabetic control group, and the effect of diabegon was compared to that of the standard insulin sensitizer drug rosiglitazone. Diabegon treatment also ameliorated the elevation of glycosylated haemoglobin, liver glycogen content, plasma insulin, homeostasis model assessment, free fatty acids, triglycerides, total cholesterol, LDL-cholesterol, and VLDL-cholesterol, whereas it increased HDL-cholesterol after 56 days of treatment (P

The aim of study was to determine the prevalence of metabolic syndrome (MetS) in people with type 2 diabetes mellitus (T2DM). National Cholesterol Education Program (NCEP) ATPIII Criteria, International Diabetes Federation and the World Health Organization (WHO) definitions were used in quantifying the metabolic syndrome and also the concordance between these three criteria’s used for identifying metabolic syndrome. Methods: This cross-sectional study involved 700 type 2 diabetic subjects from the urban areas of Gwalior Chambal region (Central India). Subjects in the age group of 28- 87 yrs were included in the study. Type I diabetics, pregnant ladies and those with chronic viral and bacterial infections and serious metabolic disorders were excluded from the study. Fasting blood glucose, Blood lipids (T-cholesterol, triglyceride, HDL-cholesterol) were assessed and anthropometry blood pressure were measured from all the subjects. Results: The Prevalence of metabolic syndrome was found to be 45.8%, 57.7% and 28% following NCEP-ATPIII Criteria, IDF and WHO definitions, respectively. Using all the three definitions the prevalence was higher in women in all age groups. ATP III and IDF criteria showed good agreement (k 0.68) compared to ATP III with WHO (k 0.54) and IDF with WHO (k 0.34) criteria. Highest prevalence was observed following IDF definition. Conclusions: A good agreement was observed between ATPIII and IDF criteria. Maximum prevalence of Metabolic syndrome was recorded when IDF criteria was followed. NCEP-ATPIII criteria for the diagnosis of MetS and this criterion reflected equal importance to the every variable and showed a good agreement between the different criteria used.

Antioxidants play a very crucial role in terms of disease incidence and its complications. Type 2 diabetes and metabolic syndrome (MetS) are now more prevalent than any other disorder. In this regard this study focuses on type 2 diabetic subjects with MetS having highest incidence of cardiovascular disease. Hence the aim of the study was to reveal the level of antioxidants and lipid peroxidation in MetS and non-MetS groups of type 2 diabetic subjects characterized by three different criteria.Present study was based on 70 type 2 diabetic subjects and 20 healthy controls. The metabolic syndrome criteria were defined by National Cholesterol Education Program (NCEP)-Adult Treatment Panel III (ATPIII), International Diabetes Federation (IDF), and World Health Organization (WHO). The selected subjects were of similar age group. The participants were selected from a diabetic camp being run in the University Campus. The antioxidant enzymes estimated were reduced glutathione (GSH), catalase (CAT), superoxide dismutase (SOD) while Thiobarbituric acid reactive substances (TBARS) measured as a marker of lipid peroxidation.The level of GSH, CAT, SOD decreases in non-MetS and MetS subjects as compared to normal. When comparison was made for GSHSOD in the mentioned groups resulted a significant differences in non-MetS and MetS compared with normal subjects. TBARS levels was increased in non-MetS and MetS group of subjects. The results indicate reduction in antioxidant enzymes and elevation of lipid peroxidation in type 2 diabetic subjects with or without MetS defined by using any of the International criteria.The study revealed that absolute reduction of antioxidant and involvement of lipid peroxidation in MetS group may lead to progressive intensification of cardiovascular disease in type 2 diabetic subjects irrespective of using any criteria.

Another anti-sweet agent gumarin is utilized as a pharmacological tool in the study of sweet-taste transduction. The commercial exploitation of this plant and their secondary metabolites are some of the major prospective of this rare medicinal herb. The focus of the present review is to achieve the potential of therapeutic value of this herb and mechanism and action of their secondary metabolites.

Molecular characterization of the insecticide resistance has become a hot research topic ever since the first disease transmitting arthropod (Anopheles gambiae) genome sequence has unveiled in 2002. A recent publication of the Culex quinquefasciatus genome sequence has opened up new opportunities for molecular and comparative genomic analysis of multiple mosquito genomes to characterize the insecticide resistance. Here, we utilized a whole genome sequence of Cx. quinquefasciatus to identify putatively active members of the detoxification supergene families, namely cytochrome P450s (P450s), glutathione-S-transferases (GSTs), and choline/carboxylesterases (CCEs). The Culex genome analysis revealed 166 P450s, 40 GSTs, and 62 CCEs. Further, the comparative genomic analysis shows that these numbers are considerably higher than the other dipteran mosquitoes. These observed speciesspecific expansions of the detoxification super gene family members endorse the popular understanding of the involvement of these gene families in protecting the organism against multitudinous classes of toxic substances during its complex (aquatic and terrestrial) life cycle. Thus, the generated data set may provide an initial point to start with to characterize the insecticide resistance at a molecular level which could then lead the development of an easy to use molecular marker to monitor the incipient insecticide resistance in field environs.

Growing awareness about the role of diet and quest for human wellness has fuelled interest in ‘Functional foods’ and functional attributes of many traditional foods are being reinvented. Flax continues to surge forward in its recognition as a functional food and has recently gained attention in the area of cardiovascular disease primarily because it is the richest known source of alpha-linolenic acid, the phytoestrogen, lignans, as well as being a good source of soluble fiber. Lignans have diverse range of biological activities and flax seeds contain a lignin derivative, secoisolariciresinol diglucoside which get metabolized into the mammalian lignans. The flax lignans influence the early risk markers of mammary and colonic carcinogenesis in animal models. Regular consumption of flaxseed products can affect serum total and low-density lipoprotein cholesterol concentrations, reduce postprandial glucose absorption, decrease some markers of inflammation and raise serum levels of the omega-3 fatty acids, ALA and eicosapentaenoic acid. The flax seed has been shown to possess significant antioxidant and anti-inflammatory functions in experimental as well as human studies. The flax seed supplementation in diet revealed potential health benefits in situations like cardiovascular risk, certain types of cancers and other metabolic disorders. There are number of studies indicating the role of raw flaxseed and its baked products in health promotion and disease prevention. This review highlights the potential of ‘flax seed’ as a ‘neutraceutical’ and its role as a protective and therapeutic medicinal food.

Cyclooxygenase-2 (Cox-2) is an inducible enzyme involved in the conversion of arachidonic acid to prostaglandin and other eicosanoids. Molecular pathology studies have revealed that Cox-2 is over-expressed in cancer and stroma cells during tumor progression, and anti-cancer chemo-radiotherapies induce expression of Cox-2 in cancer cells. Elevated tumor Cox-2 is associated with increased angiogenesis, tumor invasion and promotion of tumor cell resistance to apoptosis. Several experimental and clinical studies have established potent anti-cancer activity of NSAID (Non-steroidal anti-inflammatory drugs) and other Cox-2 inhibitors such as celecoxib. Much attention is being focused on Cox-2 inhibitors as beneficial target for cancer chemotherapy. The mode of action of Cox-2 and its inhibitors remains unclear. Further clinical application needs to be investigated for comprehending Cox-2 biological functions and establishing it as an effective target in cancer therapy.

Background Oxaliplatin is integrated in treatment strategies against a variety of cancers including radiation protocols. Herein, as a new strategy we tested feasibility and rationale of oxaliplatin in combination with radiation to control proliferation of head and neck squamous cell carcinoma (HNSCC) cells and discussed survivin-related signaling and apoptosis induction. Methods Cytotoxicity and apoptosis induced by radiation and/or oxaliplatin were examined in relation to survivin status using two HNSCC cell lines viz., Cal27 and NT8e, and one normal 293-cell line. Survivin gene knockdown by siRNA was also tested in relevance to oxaliplatin-mediated radiosensitization effects. Results Survivin plays a critical role in mediating radiation-resistance in part through suppression of apoptosis via a caspase-dependent mechanism. Oxaliplatin treatment significantly decreased expression of survivin in cancer cells within 24–72 h. Apoptotic cells and caspase-3 activity were increased parallely with decrease in cell viability, if irradiated during this sensitive period. The cytotoxicity of oxaliplatin and radiation combination was greater than additive. Survivin gene knockdown experiments have demonstrated the role of survivin in radiosensitization of cancer cells mediated by oxaliplatin. Conclusions Higher expression of survivin is a critical factor for radioresistance in HNSCC cell lines. Pre-treatment of cancer cells with oxaliplatin significantly increased the radiosensitivity through induction of apoptosis by potently inhibiting survivin.

The production of biodiesel by transesterification employing acid or base catalyst has been industrially accepted for its high conversion and reaction rates. Downstream processing costs and environmental problems associated with biodiesel production and byproducts recovery have led to the search for alternative production methods. Recently, enzymatic transesterification involving lipases has attracted attention for biodiesel production as it produces high purity product and enables easy separation from the byproduct, glycerol. The use of immobilized lipases and immobilized whole cells may lower the overall cost, while presenting less downstream processing problems, to biodiesel production. The present review gives an overview on biodiesel production technology and analyzes the factors/methods of enzymatic approach reported in the literature and also suggests suitable method on the basis of evidence for industrial production of biodiesel.

The grape is one of the most valued conventional fruits, worldwide. Although most of the parts of the grapevine are useful, primarily, the grape is considered as a source of unique natural products not only for the development of valuable medicines against a number of diseases, but also for manufacturing various industrial products. Over the last few decades, apart from the chemistry of grape compounds, considerable progress has been made towards exploring the biological activities of various grape-derived constituents. Today, it is well established that in addition to serving as food, the grape is a major source of several phytochemicals. The main biologically active and well-characterized constituent from the grape is resveratrol, which is known for various medicinal properties in human diseases. This review discusses the roles of various grape-derived phytochemicals in relation to various diseases.

Ganoderma lucidum (Ling Zhi) is a basidiomycete white rot macrofungus which has been used extensively as "the mushroom of immortality" in China, Japan, Korea and other Asian countries for 2000 years. A great deal of work has been carried out on therapeutic potential of Ganoderma lucidum. The basidiocarp, mycelia and spores of Ganoderma lucidum contain approximately 400 different bioactive compounds, which mainly include triterpenoids, polysaccharides, nucleotides, sterols, steroids, fatty acids, proteins/peptides and trace elements which has been reported to have a number of pharmacological effects including immunomodulation, anti-atherosclerotic, anti-inflammatory, analgesic, chemo-preventive, antitumor, chemo and radio protective, sleep promoting, antibacterial, antiviral (including anti-HIV), hypolipidemic, anti-fibrotic, hepatoprotective, anti-diabetic, anti-androgenic, anti-angiogenic, anti-herpetic, antioxidative and radical-scavenging, anti-aging, hypoglycemic, estrogenic activity and anti-ulcer properties. Ganoderma lucidum has now become recognized as an alternative adjuvant in the treatment of leukemia, carcinoma, hepatitis and diabetes. The macrofungus is very rare in nature rather not sufficient for commercial exploitation for vital therapeutic emergencies, therefore, the cultivation on solid substrates, stationary liquid medium or by submerged cultivation has become an essential aspect to meet the driving force towards the increasing demands in the international market. Present review focuses on the pharmacological aspects, cultivation methods and bioactive metabolites playing a significant role in various therapeutic applications.

Background The high consumption of fructose leads to the increasing incidence of insulin resistance by several unknown mechanisms. Hepatic glucose metabolism may also be an important target of fructose-induced-metabolic alterations. Aim The aim of present study was to investigate alterations in hepatic glycogenolysis, glycogenesis and gluconeogenic fluxes by feeding of 21% high fructose diet and the effects of Rosiglitazone treatment to prevent these derangements in rats. Methods Rats were maintained on normal chow and high fructose diet with or without Rosiglitazone for 8 weeks and various biochemical and gene expression measures were estimated. Results The feeding of high fructose diet impaired glucose, insulin and pyruvate tolerance tests and increased blood HbA 1c , insulin, triglyceride, free fatty acids and homeostasis model assessment after 8 weeks. In addition, high fructose diet feeding increased expression of phosphoenol-pyruvatecorboxykinase, glucose-6-phosphatase, sterol regulatory element binding proteins-1 and fatty acid synthase through enhanced expression of fork-head receptor, peroxisome proliferator activated receptor-γ-co-activator 1 and cAMP reactive element binding protein. The treatment with Rosiglitazone inhibited all these derangements, i.e. hepato-lipogenic and gluconeogenic effects of high fructose diet feeding in rats. Conclusions Together these findings suggest that high fructose diet induced hepatic gluconeogenic and lipogenic rate, and increased circulating triglycerides and free fatty acids, which may be the major risk factors for glucose intolerance, hyperglycemia and insulin resistance in rats. In such situations high fructose flux also induces transcriptional cascade of gluconeogenic enzymes through the modulation of various associated transcriptional factors.

The present study compared the relative tolerance to honey and glucose of subjects with impaired glucose tolerance or mild diabetes. Thirty individuals 35-60 years old with a proven parental (mother or father) history of type II diabetes mellitus were subjected simultaneously to an oral glucose tolerance test (GTT) and a honey tolerance test (HTT). Glucose tolerance was found to be impaired in 24 subjects, while six of the subjects were diagnosed as mildly diabetic. All subjects with impaired glucose tolerance exhibited significantly lower plasma glucose concentrations after consumption of honey at all time points of the HTT in comparison to the GTT. The plasma glucose levels in response to honey peaked at 30-60 minutes and showed a rapid decline as compared to that to glucose. Significantly, the high degree of tolerance to honey was recorded in subjects with diabetes as well, indicating a lower glycemic index of honey. Thus, it is evident from the present investigation that honey may prove to be a valuable sugar substitute for subjects with impaired glucose tolerance or mild diabetes.

Lymphatic filarial subjects with disease manifestations exhibit significantly elevated levels of immune complexes (ICs) in their circulation. The objective of the study was to explore the possible excretion of filaria‐specific soluble ICs in urine of subjects with lymphatic filariasis. Paired urine (overnight) and serum samples were analyzed for complement activating filarial antigen containing immune complexes by enzyme‐linked immunosorbent assay (ELISA). Antigen‐specific ICs were detected in urine samples of 34% of subjects with filarial disease manifestations while the frequency of occurrence was low in microfilaremic subjects. The titer of urine ICs is significantly high in subjects with chronic filariasis as compared to microfilaria (mf) carriers. The occurrence of filaria‐specific ICs in urine and their passage through the filtering structures of the kidney is suggestive of the focal or diffuse damage in those subjects. Detection of ICs in urine may provide a noninvasive means of assessing the extent of renal damage in patients with lymphatic filariasis. J. Clin. Lab. Anal. 21:46–48, 2007. © 2007 Wiley‐Liss, Inc.

Internet is transforming lives of many people in the world. Nowadays Internet has become one of the most common media to extract information of interest to researchers. The Internet is composed of a large number of smaller interconnected networks called Intranets. These Intranets connect thousands computers enabling them to share information with each other and to share various resources such as powerful super computers, software and databases of information. It has made it possible for people all over the world to effectively and inexpensively communicate with each other. The Internet has become world's biggest library where retrieval of scientific resources is only a mouse click away. The geometric growth in Internet usage is mainly due to the great success of "World Wide Web". Various useful databases on diabetes are already on 'the Net' and many more being added regularly. The present article is an attempt to provide a review of several sites that may be of great significance to the diabetes researchers before execution for new assignment/project.

Rapid diagnosis and treatment are important for preventing transmission of Mycobacterium tuberculosis. However, the diagnosis of tuberculosis continues to pose serious problems, mainly because of difficulties in differentiating between patients with active tuberculosis and those with healed lesions, normal mycobacterium boris BCG (Bacillus Calmette Guerin) vaccinated individuals, and unvaccinated Manteux positives. Physicians still rely on conventional methods such as Ziehl‐Neelsen (ZN) staining, fluorochrome staining, sputum culture, gastric lavage, and other non‐traditional methods. Although the tuberculin test has aided in the diagnosis of tuberculosis for more than 85 years, its interpretation is difficult because sensitization with nontuberculous mycobacteria leads to false‐positive tests. There have been numerous unsuccessful attempts to develop clinically useful serodiagnostic kits for tuberculosis. A number of proteinaceous and nonprotein antigens (such as acyltrehaloses and phenolglycolipids) have been explored from time to time for the development of such assays but they have not proved to be clinically useful. It has been difficult to develop an ELISA utilizing a suitable antigen because M. tuberculosis shares a large number of antigenic proteins with other microorganisms that may or may not be pathogenic. With the advent of molecular biology techniques, there have been significant advances in nucleic acid‐based amplification and hybridization, which are helping to rectify existing flaws in the diagnosis of tuberculosis. The detection of mycobacterial DNA in clinical samples by polymerase chain reaction (PCR) is a promising approach for the rapid diagnosis of tuberculous infection. However, the PCR results must be corrected for the presence of inhibitors as well as for DNA contamination. In the modern era of genetics, marked by proteomics and genomics, the day is not far off when DNA chip‐based hybridization assays will instantly reveal mycobacterial infections. J. Clin. Lab.
