Exploring the Potential of Plant Bioactive Compounds against Male Infertility: An In Silico and In Vivo Study.

Infertility is a well-recognized multifactorial problem affecting the majority of people who struggle with infertility issues. In recent times, among infertility cases, the male factor has acquired importance, and now it contributes to approximately half of the infertility cases because of different abnormalities. In the current study, we used natural phytochemicals as potential drug-lead compounds to target different receptor proteins that are involved in the onset of male infertility. A set of 210 plant phytochemicals were docked counter to active site residues of sex hormone-binding globulin, a disintegrin and metalloproteinase 17, and DNase I as receptor proteins. On the basis of binding scores and molecular dynamics simulation, the phytochemicals tricin, quercetin, malvidin, rhamnetin, isorhamnetin, gallic acid, kaempferol, esculin, robinetin, and okanin were found to be the potential drug candidates to treat male infertility. Molecular dynamics simulation showed tricin as a strong inhibitor of all selected receptor proteins because the ligand-protein complexes remained stabilized during the entire simulation time of 100 ns. Further, an in vivo study was designed to evaluate the effect of tricin in male rats with nicotine-induced infertility. It was explored that a high dose of tricin significantly reduced the levels of alanine transaminase, aspartate transaminase, urea, creatinine, cholesterol, triglyceride, and low-density lipoprotein and raised the level of high-density lipoprotein in intoxicated male rats. A high dose of tricin also increased the reproductive hormones (i.e., testosterone, luteinizing hormone, follicle-stimulating hormone, and prolactin) and reduced the level of DHEA-SO4. The phytochemical (tricin, 10 mg/kg body weight) also showed significant improvement in the histo-architecture after nicotine intoxication in rats. From the current study, it is concluded that the phytochemical tricin could serve as a potential drug candidate to cure male infertility.

Investigation of boron-doped graphene oxide anchored with copper sulphide flowers as visible light active photocatalyst for methylene blue degradation.

The non-biodegradable nature of waste emitted from the agriculture and industrial sector contaminates freshwater reserves. Fabrication of highly effective and low-cost heterogeneous photocatalysts is crucial for sustainable wastewater treatment. The present research study aims to construct a novel photocatalyst using a facile ultrasonication-assisted hydrothermal method. Metal sulphides and doped carbon support materials work well to fabricate hybrid sunlight active systems that efficiently harness green energy and are eco-friendly. Boron-doped graphene oxide-supported copper sulphide nanocomposite was synthesized hydrothermally and was assessed for sunlight-assisted photocatalytic degradation of methylene blue dye. BGO/CuS was characterized through various techniques such as SEM-EDS, XRD, XPS, FTIR, BET, PL, and UV-Vis DRS spectroscopy. The bandgap of BGO-CuS was found to be 2.51 eV as evaluated through the tauc plot method. The enhanced dye degradation was obtained at optimum conditions of pH = 8, catalyst concentration (20 mg/100 mL for BGO-CuS), oxidant dose (10 mM for BGO-CuS), and optimum time of irradiation was 60 min. The novel boron-doped nanocomposite effectively degraded methylene blue up to 95% under sunlight. Holes and hydroxyl radicals were the key reactive species. Response surface methodology was used to analyze the interaction among several interacting parameters to remove dye methylene blue effectively.

Virtual screening of phytochemicals by targeting multiple proteins of severe acute respiratory syndrome coronavirus 2: Molecular docking and molecular dynamics simulation studies.

OBJECTIVE: Medicinal herbs are being investigated for medicationhg development against SARS-CoV-2 as a rich source of bioactive chemicals. One of the finest approaches for finding therapeutically effective drug molecules in real time is virtual screening scheme such as molecular docking in conjunction with molecular dynamics (MD) simulation. These virtual techniques provide an ample opportunity for the screening of plausible inhibitors of SARS-CoV-2 different target proteins from a comprehensive and extensive phytochemical library. The study was designed to identify potential phytochemicals by virtual screening against different receptor proteins. METHODS: In the current study, a library of plant secondary metabolites was created by manually curating 120 phytochemicals known to have antimicrobial as well as antiviral properties. In the current study, different potential phytochemicals were identified by virtual screening against various selected receptor proteins (i.e., viral main proteases, RNA-dependent RNA polymerase (RdRp), ADP ribose phosphatase, nonstructural proteins NSP7, NSP8, and NSP9) which are key proteins responsible for transcription, replication and maturation of SARS-CoV-2 in the host. Top three phytochemicals were selected against each viral receptor protein based on their best S-scores, RMSD values, molecular interactions, binding patterns and drug-likeness properties. RESULTS: The results of molecular docking study revealed that phytochemicals (i.e., baicalin, betaxanthin, epigallocatechin, fomecin A, gallic acid, hortensin, ichangin, kaempferol, limonoic acid, myricetin hexaacetat, pedalitin, quercetin, quercitrin, and silvestrol) have strong antiviral potential against SARS-CoV-2. Additionally, the reported preeminent reliable phytochemicals also revealed toxicity by no means during the evaluation through ADMET profiling. Moreover, the MD simulation study also exhibited thermal stability and stable binding affinity of the pedalitin with SARS-CoV-2 RdRp and SARS-CoV-2 main protease which suggests appreciable efficacy of the lead optimization. CONCLUSION: The biological activity and pharmacologically distinguishing characteristics of these lead compounds also satisfied as repurposing antiviral drug contenders and are worth substantial evaluation in the biological laboratory for the recommendation of being plausible antiviral drug candidates against SARS-CoV-2.

Isolation and characterization of peroxidase P7-like gene and Rab-GDI like gene from potential medicinal plants: A step toward understanding cell defense signaling.

Defensin genes form part of a plant's defense system and are activated when exposed to biotic or abiotic stress. They play a vital role in controlling many signaling pathways involved in various plant defense mechanisms. This research aimed to isolate and characterize novel defensin genes from selected medicinally important plants to explore their signaling mechanisms and defense associated roles for breeding. The DNA of Albizia lebbeck and Moringa oleifera was subjected to PCR amplification using gene-specific primers of defensin genes. Two novel defensin genes were isolated in each species, with sequence lengths of 300 bp in A. lebbeck and 150 bp in M. oleifera. In-silico analysis undertaken to retrieve and align their orthologous sequences revealed 100% similarity of the A. lebbeck gene with the Musa acuminate peroxidase P7-like gene and 85% similarity of the M. oleifera gene with the Manihot esculenta GDP dissociation inhibitor gene. The reliability, stability and physiochemical properties of homology models of these sequences was confirmed through online computational studies. This preliminary study confirmed the presence of novel genes with peroxidase P7 and Rab GDP dissociation inhibitor gene-like activity in A. lebbeck and M. oleifera, respectively, and their potential defense role in plants. Thus, the defensin genes of both species could be used in the synthesis of transgenic self-defensive plants with increased disease resistance and as potential candidates for improved crop production and thraputic formulation in the future.

Antibacterial properties of Apis dorsata honey against some bacterial pathogens.

Now-a-days, different bioproducts are being used extensively for the welfare of mankind. However, for proper utility of any bioproduct, the exact biotechnological potential of that product should be explored. Honey is produced in almost every country on the planet. It has long been used as a medicinal agent in addition to its broader use as a popular food throughout the human history. It can be used to treat various diseases without causing any negative side effects. In the present study, the antibacterial potential of honey produced by A. dorsata was investigated at its variable concentrations (25, 50, 75 and 100 %) against four pathogenic bacterial species. The highest antimicrobial action was seen against E. coli at 100 % concentration of the honey while showing zone of inhibition of 37.5 ±â€¯3.5 mm. However, the lowest antibacterial action was observed against E. faecalis. The overall order of growth inhibition by the honey at its 100 % concentration for the implicated bacterial species appeared as: E. coli ˃ P. aeruginosa ˃ S. aureus ˃ E. faecalis. The honey couldn't show antibacterial action at its 25 % concentration. Our findings of the present study will be helpful for utility of the honey as an alternative medicine for curing different complications caused by microbial pathogens.

Antioxidant and antibacterial activities of Artemisia absinthium and Citrus paradisi extracts repress viability of aggressive liver cancer cell line.

BACKGROUND: Numerous reports show that herbal medicines can be utilized in the treatment of different liver disorders. In this study, antioxidant, antibacterial, and anticancer activities of individual as well as combined 80% ethanolic extracts of Artemisia absinthium leaves and Citrus paradisi peels were investigated. METHODS AND RESULTS: Values of total phenolic contents (TPC), total flavonoid contents (TFC), DPPH-radical scavenging activity, and ferric reducing antioxidant power (FRAP) were measured to explore the antioxidant capacity. To assess antibacterial activity, four bacterial strains (Escherichia coli, Staphylococcus aureus, Salmonella enterica, and Klebsiella pneumoniae) were used. Anticancer activity was assessed on Huh-7 (liver cancer) and Vero (non-cancerous) cell lines. FRAP activity of combined plants extract was higher as compared to their individual effect; the trend did not hold in the case of DPPH-radical scavenging activity. Antibacterial activity of combined extracts by disk diffusion method was observed only against E.coli. MTT results indicated that both plants had a cytotoxic effect on Huh-7 cell line but did not show any effect on Vero cell line. Our data showed a strong negative correlation between the amount of TPC, TFC, & DPPH radicals-scavenging activity and viability of Huh-7 cell line.However, no effect was shown on the non-cancerous cell line. CONCLUSION: The ethanolic extracts of Artemisia absinthium leaves and Citrus paradisi peels can be used against liver cancer because of their antioxidant, antibacterial, and anticancer activities.

Enhancement of nutraceutical and antioxidant potential of sunflower hybrid seed varieties through chemical priming.

Pathogenic agents cause an increased risk of various fatal diseases and there is a need to reduce this risk using medicinal plants and their seeds. The present research work was designed to study the efficacy of different sunflower seed hybrid varieties (i.e. FH622, FH620, FH615, FH613 and FH545) chemically primed with potassium nitrate as natural antioxidant and antimicrobial agent. Antioxidant potential was determined using DPPH test, reducing power, TPC and TFC. Antibacterial activity was determined against Gram positive and Gram negative bacterial species. After one week, the germination data including mean germination and percentage of final emergence was calculated. It was found that seed varieties FH620 and FH615 have higher values of mean germination as compared to FH545 while FH615 has higher percentage of final emergence as compared to FH620 and FH545. High phenolic and flavonoid contents were observed in FH620 and FH615 as compared to FH545 variety. It was also observed that seed variety FH615 when treated with KNO3 solution had significantly high germination as well as antioxidant parameters and antibacterial activity as compared to other varieties. Similarly FH615 showed high antibacterial activities against Gram positive Staphylococcus aureus and Gram-negative Escherichia coli bacteria. This study showed that all selected sunflower hybrids have good antioxidant and antibacterial potentials that would further be used for different trials to cure different pathogen related diseases, and these are natural sources of antioxidants for commercial and therapeutic applications.

Antibacterial and antibiofilm properties of traditional medicinal plant from Sheikh Buddin range.

During current project, antibacterial and antibiofilm properties of traditional medicinal plant Ziziphus nummularia leaf extract and various fractions was investigated. The plant leaves were dried and extracted using 90% methanol followed by sequential fractionation using liquid-liquid fractionation. The fractions of a diverse polarity including chloroform, n-hexane, methanol and ethyl acetate and aqueous extracts were obtained that was further analysed by using HPLC. The phytochemical screening indicated presence of saponins, triterpenes and flavonoids. During DPPH assay, the methanolic fraction presented highest activity (IC50 193.1µg/mL), followed by ethyl acetate (IC50 220µg/mL) and chloroform (IC50 263µg/mL) fractions respectively. During FRAP assay, FRAP value for Z. nummularia extract 20.43µM. Among fractions, ethyl acetate fraction presented highest FRAP value (370.2µM), followed by chloroform (204µM) and methanolic (249µM) fractions. The antimicrobial activity of chloroform fraction was significantly high against P. aureginosa (6mm), L. monocytogenes, S. aureus (5mm), K. pneumoniae, B. Subtillus and E. coli (4mm). The ethyl acetate part presented significant activity (MIC 4mg/mL) against S. aureus, B. Subtillus and L. monocytogenes. The total extract and fractions were further tested for MBC and the MBC for ethyl acetate fractions was 4mg/mL, whereas all other fractions exhibited MBC >10mg/mL. No activity was recorded against Aspergillus niger. During antibiofilm assay, n-hexane fraction presented highest inhibition (88%) followed by ethyl acetate (69%) chloroform (65%) fractions. It was concluded that Z. nummularia possess moderate antimicrobial and antibiofilm activities. Further a synergistic effect is suggested in formulation having Z. nummularia.

Comparative study on effects of citric and lactic acid treatment on morphological, functional, resistant starch fraction and glycemic index of corn and sorghum starches.

The present study isolated starch from corn and sorghum grains through wet milling procedure. Sorghum starch is considered an alternative to corn starch in future, due to similar functional properties. However, agronomically sorghum is a cheap input cost crop compared to sorghum and can grow in drought hit areas. Lactic acid and citric acid modifications along with heat-moisture treatments were performed on both sorghum and corn grains followed by their comparison in terms of functional, textural, thermal, pasting and digestibility characteristics. For both corn and sorghum starches, the resistant starch increased after chemical modifications. The RS content of acid and acid-heat moisture treated starches were in the range of 77.9-90%, significantly higher than those of native starches (64.6-68.8%). The modifications increased the gelatinization temperature, decreased the peak and cold paste viscosity of starches. Chewiness significantly reduced after lactic and citric acid treatment along with heat-moisture treatments. The crystallinity to amorphous ratio measured through Fourier Transform infrared reduced after all chemical treatments. Percent light transmittance was further reduced after heat-moisture treatments, however the effect on corn starch was more pronounced i.e. it declined from 16.5 to 5.2%. The acid-heat moisture treatments had considerably lowered the glycemic index of starch. The GI reduced from 74 to 49.7 and 60 to 48.5 when treated with acid in the presence of heat and moisture. Thus, these starches could be used in production of low-calorie foods.

Magneto-Priming Improved Nutraceutical Potential and Antimicrobial Activity of Momordica charantia L. Without Affecting Nutritive Value.

The need for some economic strategies for increased growth and nutraceuticals of medicinal plants is well acknowledged now. It was hypothesized that external magnetic field treatment (MFT) of seeds affecting internal magnet of cells may affect growth and metabolism. In this study, seeds were subjected to pre-sowing magnetic field (50 mT at 5 mm for 5 s). At vegetative stage, the leaf growth, chlorophyll content, catalase (CAT), peroxidase (POD), amino acids, proteins, flavonoids, soluble sugars, total soluble phenolics, carotenoids, anthocyanins, phenolic profile (HPLC based), and antimicrobial activity of leaves (in terms of the minimum inhibitory concentration against Staphylococcus aureus and Pseudomonas aeruginosa) were studied. Yield was evaluated for nutritive components in fruit (peel+pulp) and peel. MFT improved germination percentage, growth, leaf chlorophyll, antimicrobial activity, peel amino acids, phenolics, and POD with negligible effect on fruit nutritive value. Moreover, photosynthetic pigments and cinnamic acid exhibited direct correlation with antimicrobial potential against both pathogens. However, sinapic acid showed positive correlation against Staphylococcus aureus only. Cinnamic acid, coumaric acid, syringic acid, and quercetin were in direct correlation against Pseudomonas aeruginosa; it was directly correlated with total flavonoids too. In conclusion, magnetic field can be used to manipulate plant cell metabolism promising improvement of growth, antimicrobial activity, and phenolics of interest.

Low vitamin D status in nursing Pakistani mothers in an environment of ample sunshine: a cross-sectional study.

BACKGROUND: The maternal 25-hydroxy vitamin D (25OHD) insufficiency is related to adverse maternal and neonatal outcome. The 25OHD content of breast milk is dependent on 25OHD status of the mothers. We undertook this study to ascertain the 25OHD status and its determinants in the nursing mothers of the south Punjab, Pakistan. METHODS: We recruited 67 mothers for this cross-sectional study by convenience sampling from August 2010 to June 2011 to ascertain their serum 25OHD level & its determinants. We used SPSS 23.0 for analyses. RESULTS: The mean age of the mothers was 25.75 ± 4.4 years. The median age (and mode) was 25 years (range 18-37 years). The majority of mothers were less than 25 years of age (62.7%), uneducated (68.7%), from rural area (70.1%), lived in open houses with ample sun exposure (85.1%) and belonged to low socioeconomic strata (71.6%). Serum 25OHD ranged from 7.2 to 43.8 nmol/L with a mean of 20.87 ± 7.69 nmol/L. The median and mode were 21.8 nmol/L & 24.0 nmol/L, respectively. The proportion of mothers with 25OHD < 20 nmol/L (severe deficiency) was 44.8%, < 30 nmol/L (deficiency) 49.3% and < 50 nmol/L (insufficiency) 5.9%. All had 25OHD below 50 nmol/L. The oral supplementation with vitamin D (vD) was the only significant determinant of vitamin D sufficiency. CONCLUSIONS: The majority of Pakistani mothers in south Punjab are vD deficient & universal vD supplementation is the need of the hour to improve health outcomes in mothers & infants.

Short Communication - Urease inhibitory activity of Hippophae rhamnoids and Cassia fistula.

The rational use of plants as medicine is traced back over five epochs to ancient documents of early civilizations and is certainly as old as mankind. These medicines originally developed from crude drugs like tinctures and tinctures. Minimum 119 chemical substances are derived from 90 plant species and used all over the world as medicines, several of them containing compounds derived from or modelled after naturally occurring lead molecules and 74% of these derived from orthodox medicinal plants. 252 drugs (11%) are believed to be basic and essential by the WHO and are exclusively of plant origin. We have examined anti-urease activity of ethyl alcohol (Et-OH) and methyl alcohol (Me-OH) extracts of H. rhamnoides and Cassia fistula. Berthelot assay was used for the determination of anti-urease activity. The enzyme activity and inhibition was measured through catalytic effects of urease on urea by measuring change in absorbance in the absence and in the presence of inhibitor at 625nm using UV spectrophotometer. In the study, both Et-OH and Me-OH extracts of H. rhamnoides (91.69%±1.21) and C. fisstula (79.44%±0.55) showed stronger action against urease activity. An overview on the medicinal uses of H. rhamnoides and C. fisstula showing anti-urease activity may predict their possible alternative use for stomach problems. This study may help to explain the beneficial effects of these plants against stomach infection associated with pathogenic strains of H. pylori as Urease is the most prominent protein component of H. pylori.

Anti-avian influenza virus H9N2 activity of aqueous extracts of Zingiber officinalis (Ginger) and Allium sativum (Garlic) in chick embryos.

In the present study, anti-Avian influenza virus H9N2 activity of aqueous extracts (5, 10, 15, 20, 25%) of Zingiber officinalis and Allium sativum was evaluated. Embryo-toxicity was evaluated by histopathological scoring of Chorio-allantoic membrane of chick embryos. Cytotoxicity of extracts was determined by MTT assay on Vero cells. Aqueous extract of ginger had antiviral activity at 10, 15, 20 and 25% while garlic had activity at 15, 20 and 25%. Histopathological scoring of chorio-allantoic membrane for aqueous extracts (5, 10, 15, 20, 25%) of ginger (0.66±0.57, 1.33±0.57, 1.66±0.57, 2.66±0.57, 3.66±0.57, respectively) and garlic (1.00±0.00, 1.33±0.57, 2.00±0.00, 2.33±0.57, 3.66±0.57, respectively) was concentration dependant. MTT assay revealed cytotoxicity of both plants was also concentration dependent. Extracts of ginger (5, 10, 15, 20, 25%) had lower cytotoxicity (71, 59, 28, 22, 0 % cell survival, respectively) as compared to garlic (61, 36. 20, 11, 3% cell survival, respectively). Overall results revealed that concentration of aqueous extract of ginger (10%), showing antiviral activity against H9N2, was less toxic to vero cells (> 50% cell survival). It is insinuated that ginger may have anti- Avian influenza virus H9N2 potential and its active compounds needs further investigations.

Interactive effects of phosphorus and Pseudomonas putida on chickpea (Cicer arietinum L.) growth, nutrient uptake, antioxidant enzymes and organic acids exudation.

Phosphorus (P) availability in alkaline soils of arid and semi-arid regions is a major constraint for decreased crop productivity. Use of plant growth promoting rhizobacteria (PGPR) may enhance plant growth through the increased plant antioxidation activity. Additionally, PGPR may increase nutrient uptake by plants as a result of induced root exudation and rhizosphere acidification. The current study was aimed to investigate combined effects of P and Pesudomonas putida (PGPR) on chickpea growth with reference to antioxidative enzymatic activity and root exudation mediated plant nutrient uptake, particularly P. Half of the seeds were soaked in PGPR solution, whereas others in sterile water and latter sown in soils. Plants were harvested 8 weeks after onset of experiment and analyzed for leaf nutrient contents, antioxidant enzymes activities and organic acids concentrations. Without PGPR, P application (+P) increased various plant growth attributes, plant uptake of P and Ca, soil pH, citric acid and oxalic acid concentrations, whereas decreased the leaf POD enzymatic activity as compared to the P-deficiency. PGPR supply both under -P and +P improved the plant growth, plant uptake of N, P, and K, antioxidative activity of SOD and POD enzymes and concentrations of organic acids, whereas reduced the rhizosphere soil pH. Growth enhancement by PGPR supply was related to higher plant antioxidation activity as well as nutrient uptake of chickpea including P as a result of root exudation mediated rhizosphere acidification.

Engaging with community-based public and private mid-level providers for promoting the use of modern contraceptive methods in rural Pakistan: results from two innovative birth spacing interventions.

BACKGROUND: Family planning (FP) interventions aimed at reducing population growth have negligible during the last two decades in Pakistan. Innovative FP interventions that help reduce the growing population burden are the need of the hour. Marie Stopes Society--Pakistan implemented an operational research project--'Evidence for Innovating to Save Lives', to explore effective and viable intervention models that can promote healthy timing and spacing of pregnancy in rural and under-served communities of Sindh, Punjab and Khyber Pakhtunkhwa provinces of Pakistan. METHODS: We conducted a quasi-experimental (pre- and post-intervention with control arm) study to assess the effectiveness of each of the two intervention models, (1) Suraj model (meaning 'Sun' in English), which uses social franchises (SF) along with a demand-side financing (DSF) approach using free vouchers, and (2) Community Midwife (CMW) model, in promoting the use of modern contraceptive methods compared to respective controls. Baseline and endline cross-sectional household surveys were conducted, 24 months apart, by recruiting 5566 and 6316 married women of reproductive age (MWRA) respectively. We used Stata version 8 to report the net effect of interventions on outcome indicators using difference-in-differences analysis. Multivariate Cox proportional hazard regression analysis was used to assess the net effect of the intervention on current contraceptive use, keeping time constant and adjusting for other variables in the model. RESULTS: The Suraj model was effective in significantly increasing awareness about FP methods among MWRA by 14% percentage points, current contraceptive use by 5% percentage points and long term modern method--intrauterine device (IUD) use by 6% percentage points. The CMW model significantly increased contraceptive awareness by 28% percentage points, ever use of contraceptives by 7% percentage points and, IUD use by 3% percentage points. Additionally the Suraj intervention led to a 35% greater prevalence (prevalence ratio: 1.35, 95% CI: 1.22-1.50) of contraceptive use among MWRA. CONCLUSION: Suraj intervention highlights the importance of embedding subsidized FP services within the communities of the beneficiaries. The outcomes of the CMW intervention also improved the use of long-term contraceptives. These findings indicate the necessity of designing and implementing FP initiatives involving local mid-level providers to expand contraceptive coverage in under-served areas.

Parental beliefs and practice of spiritual methods for their sick children at a tertiary care hospital of Pakistan- a cross sectional questionnaire study.

BACKGROUND: Complementary and alternative medicine (CAM) comprises a variety of health care systems, practices, and products that are not usually thought to be part of allopathic medicine. This study investigated the parental beliefs and practices for use of spiritual methods in the treatment and early recovery of their children. METHODS: We performed a cross-sectional, descriptive study with convenience sampling of parents/caregivers of sick children who were admitted to the Children's Hospital in Multan. A trained interviewer collected the data. RESULTS: A total of 1280 forms were analyzed. The majority of respondents were mothers (1053, 82.4%), they resided in Multan (817, 63.8%), and were not educated (754, 58.9%). A total of 420 (32.8%) respondents had a low socioeconomic background, 601 (47%) were middle class, and 259 (20.2%) were upper class. Grandmothers/mothers advised spiritual methods in the majority of respondents (605, 85.9%). The parents used a variety of spiritual methods in 704 (55%) children. Economic status and education showed an inverse relation with the use of CAM. A total of 809 (63.2%) respondents believed that only a drug would heal the disease, while 575 (44.9%) believed that spiritual methods have a 25%-50% role in healing. A total of 1269 (99.1%) respondents believed that allopathic drugs are needed for healing, while only 0.9% considered otherwise. CONCLUSION: The majority of people believe that CAM is a contributory factor towards healing and does not interfere with allopathic treatment.

Effects of Vitamin D supplementation on physical activity of patients with Heart Failure.

OBJECTIVE: To see the role of Vitamin D supplementation on physical status of patients suffering from Congestive Heart Failure (dilated cardiomyopathy). METHODS: In this nonrandomized clinical trial, Forty three Patients with dilated cardiomyopathy who were not showing any significant improvements in physical performance on optimal treatment of heart failure were included. Vitamin D (200,000 IU) supplementation on weekly basis for a period of 12 weeks was added to heart failure treatment. And its effect was seen on 6 minutes' walk distance and Pro-BNP levels. SPSS version 19 was used for data analysis. Dependent sample t-test was used to see the significant effect of vitamin D supplementation on pre- intervention vitamin D levels, 6MWD and Pro-BNP. Taking p-value <0.05 as significant. RESULTS: On clinical assessment most of the patients were in NYHA class II (65%), the percentages of NYHA Class I, III and IV was 19%, 9% and 7% respectively. The baseline mean vitamin D level of the study group was 16.59±3.54ng/ml and it raised to 31.97±3.64ng/ml after 12 weeks of supplementation with vitamin D, p value<0.0005. The mean distance travelled by the study group before the intervention was 806±380ft while it increased to 945±393ft after the intervention, p value of 0.008. The mean of pro-BNP level of the study group before the intervention was 1024±635 while it improved to 159±80 after the intervention with a significant p value<0.0005. CONCLUSION: Vitamin D supplementation decreases the severity of HF as reflected by reduction in serum pro-BNP levels and significant increase in six minutes' walk distance.

PREVALENCE OF CONGENITAL HEART DISEASE IN RURAL COMMUNITIES OF PAKISTAN.

BACKGROUND: Prevalence of Congenital Heart Disease (CHD) is well established in most of the developed countries, where childbirth is obligatory in hospitals and allied facilities. In rural Pakistan the situation is reverse, where most of deliveries take place in homes by traditional birth attendants' therefore true prevalence of CHD in our population is unknown. In rural Pakistan almost 80% children are born at home hence the figures are unknown. This study was designed, to determine the prevalence of congenital heart disease in rural Pakistan. METHODS: During a cross-sectional survey of rural population belonging to major ethnic groups living in three provinces of Pakistan to determine the prevalence of rheumatic heart disease (RHD), CHD rates were calculated as a sub study. Nine thousand four hundred and seventy-six (9476) subjects of all ages were screened using cluster sampling technique. Socio-demographic variables were recorded. Auscultation and short physical examination performed for initial screening and final diagnosis was confirmed on M-mode/2D/Doppler. RESULTS: Thirty two patients had RHD, 25 Patients identified with CHD and another 7 patients had mixed CHD & RHD. Overall prevalence for CHD was 3.4/1000. The commonest lesion was Atrial Septal Defect (ASD) 40%, Ventricular Septal Defect (VSD) 35%, Aortic Stenosis (AS) 10%, Atrio Ventricular Septal Defect (AVSD) 5%. CONCLUSION: This is the first study to report CHD prevalence from multiethnic representative sample from rural communities of Pakistan. Apparently CHD rate seems less compared with facility based data because records of still stillbirths are not available and autopsies are not performed as routine. Very high infant mortality from rural areas of Pakistan also favours high prevalence for CHD; however these figures represent an overall picture of CHD in a community where medical facilities are lacking.

Expression profiling of bioactive genes from Moringa oleifera.

Plants are under constant assault by biotic and abiotic agents. When an elicitor is prologued, an immense reprogramming of plant gene expression and defense responses are initiated, which could be a natural source for potential drug development and insertional mutagenesis. In this regard, differential expression analysis of a medicinal plant Moringa oleifera was performed for bioactive genes at seedling stage, using differential display-RT-PCR technique. Infected seedlings with a fungus Fusarium solani collected at different time intervals, showed a massive change in their gene expression profile. The data analysis revealed that at least 150 pathogen-induced and about 60 suppressed genes were differentially expressed at 8-h postinoculation of the biotic stress. Fifty-five selective genes were disunited and reamplified. Sequence analysis of these potential genes illustrated that these genes had properties of some induced peroxidase mRNA, cell proliferation, others were mitogen activated protein kinases, ribosomal protein genes, defense regulating genes, and a few also had structural properties. Further studies about the utility of these genes in plant metabolism could assist to develop improved transgenic breeds with enhanced value of infection tolerance not only of M. oleifera but of other cultivars also.

IUD discontinuation rates, switching behavior, and user satisfaction: findings from a retrospective analysis of a mobile outreach service program in Pakistan.

BACKGROUND: In Pakistan, the uptake rate for the intrauterine device (IUD) is very low at 2.5%. The most popular modern contraceptive methods in Pakistan are female sterilization and use of condoms. The Marie Stopes Society established its mobile outreach service delivery program with the aim of increasing use of modern quality contraceptive services, including the long-term reversible IUD, by women living in hard-to-reach areas. The present study attempts to assess IUD discontinuation rates and associated factors, including switching behavior and level of satisfaction with this type of service delivery. METHODS: Using a cross-sectional approach, we contacted 681 women who had received an IUD from the Marie Stopes Society mobile outreach program during July and August 2009. Successful interviews were conducted with 639 of these women using a structured questionnaire. The data were analyzed with Stata 11.2 using simple descriptive Chi-square and Cox proportional techniques. RESULTS: Analysis revealed that 19.4% (95% confidence interval 16.3-22.5) of the women discontinued use of their IUD at 10 months and, of these women, the majority (69.4%) cited side effects as the main reason for discontinuation. Other factors, such as geographical catchment province, age of the woman, history of contraceptive use before IUD insertion, and side effects following insertion of the device, were found to be significantly associated with IUD. Amongst the women who had their IUD removed, 56.5% did not switch to any other contraceptive method, while 36.3% switched to either short-term or traditional methods, such as withdrawal, rhythm, and folk methods.
