Effect of different plant hormones on callus induction in Gymnema sylvestris R.Br. (Asclepiadaceae)

The use of Gymnema sylvestris as an alternative remedy for diabetes was well known from ancient times in India and the plant is valuable for its pharmaceutical properties. The present study describes callus induction of the plant G. sylvestris using internodal explants and the influence of different plant hormones like 2,4-D, kinetin, IAA, BAP on the growth of calli. Internodes were proved to be the best explant for culture, which were grown on MS basal medium (Murashige and Skoog, 1962) with differentconcentration of various growth regulators. The standard plant tissue culture protocol for callus culture and/or micropropagation was adopted. The highest efficiency of callus formation was observed in themedium containing different concentration of 2,4-D and kinetin

Septic Abortion Managed in a Tertiary Hospital in West Bengal

Background: Septic abortion is still a challenging problem and a major cause of maternal mortality and morbidity in developing countries.Aim: The present study was conducted to estimate incidence, causes, risk factors, associated microorganisms, and treatment modalities of cases of septic abortion managed in a tertiary health care in West Bengal.Subjects and Methods: It was a cross‑sectional study carried out in Burdwan Medical College and Hospital in West Bengal between July 2011 and June 2012. On admission a thorough history was taken, examination was done, and investigations were carried. Depending on the examination findings the cases were grouped into three grades‑grade I: The infection localized in the uterus; grade II: The infection spread beyond the uterus to the parametrium, tubes, and ovaries or pelvic peritoneum; grade III: Generalized peritonitis and/or endotoxic shock or jaundice or acute renal failure. Statistical analysis was done by using Epi Info™ software (Version 3.5.1, CDC) after proper arrangement of all the data in tabular form and presented as simple percentage.Results: During the period, 1297 cases of abortion were admitted among which 107 were septic abortions, thus giving the incidence of the latter as 8.2% (107/1297). Forty‑three percent cases of septic abortion (46/107) were in grade I, 21.5% (23/107) in grade II, and 35.5% (38/107) in grade III. The modal age group of the patients was 15‑25 years (49.5%). Majority of the subjects were married (77.6%; 83/107) and multiparous (60.7%; 65/107). Similarly, most of them (71%; 76/107) were from low socioeconomic class. Ninety percent of the patients (96/107) had induced abortion. The common clinical features at presentation were pallor (88.8%; 95/107) and fever (86.0%; 92/107). Escherichia coli (62.6%; 67/107) and Klebsiella pneumonia (32.75%; 35/107) were the most common organism isolated. The case fatality from septic abortion in this study was 13.1% and the condition accounted for 15.4% of total maternal mortality within the period reviewed.Conclusion: The incidence of septic abortion in this study is relatively high, and majority of the cases resulted from attempted termination of pregnancy. It is a significant contributor to maternal mortality. Promotion of family planning and legalization of abortion services will go a long way in reducing the incidence of septic abortion and itsassociated complications. Keywords: Asia, management, maternal mortality, outcome, septic abortio

Antihydrogen-hydrogen elastic scattering at thermal energies using an atomic-orbital technique

In view of the recent interest in the trapping of antihydrogen atom (H) over bar, at very low temperatures, (H) over bar -H scattering has been investigated at low incident energies using a close-coupling model with the basis set (H) over bar (1s,2s,2 (p) over bar)+H(1s,2s,2 (p) over bar). The predicted s-wave elastic phase shifts, scattering length, and effective range are in a good agreement with the other recent predictions of Jonsell and of Armour and Chamberlain. The results indicate that the atomic orbital expansion model is suitable to study the (H) over bar -H scattering at ultracold temperatures.67

Rapid Veterinary Diagnosis of Bovine Reproductive Infectious Diseases from Semen Using Paper-Origami DNA Microfluidics

The health and well-being of cattle is an important issue in maintaining and increasing global agricultural output. In dairy production within low and middle income countries (LMICs), there is a significant biosensing challenge in detecting sexually transmitted infection (STI) pathogens during animal husbandry, due in part to difficulties associated with the limited infrastructure for veterinary medicine. Here we demonstrate low-cost, multiplexed, and sample-to-answer paper-origami tests for the detection of three bovine infectious reproductive diseases in semen samples, collected at a test site in rural India. Pathogen DNA from one viral pathogen, bovine herpes virus-1 (BoHV-1), and two bacteria (Brucella and Leptospira) was extracted, amplified (using loop-mediated isothermal amplification, LAMP), and detected fluorescently, enabling <1 pg (∼ from 115 to 274 copies per reaction) of target genomic DNA to be measured. Data was collected as a fluorescence signal either visually, using a low-cost hand-held torch, or digitally with a mobile-phone camera. Limits of detection and sensitivities of the paper-origami device for the three pathogens were also evaluated using pathogen-inoculated semen samples and were as few as 50 Leptospira organisms, 50 CFU Brucella, and 1 TCID50 BoHV-1. Semen samples from elite bulls at a germplasm center were also tested in double-blind tests, as a demonstrator for a low-cost, user-friendly point-of-care sensing platform, for in-the-field resource-limited regions. The sensors showed excellent levels of sensitivity and specificity, and for the first time a demonstrated ability of the application of paper microfluidics devices for the diagnosis multiple infectious diseases from semen samples

One-year treatment with mometasone furoate in chronic obstructive pulmonary disease

Many patients with chronic obstructive pulmonary disease (COPD) are treated with twice daily (BID) inhaled corticosteroids (ICS). This study evaluated whether daily PM mometasone furoate administered via a dry powder inhaler (MF-DPI) was equally effective compared to twice daily dosing

Migraine and restless legs syndrome: is there an association?

Occasional clinical reports have suggested a link between migraine and restless legs syndrome. We undertook a systematic review of the evidence, which supports this association, and consider possible shared pathogenic mechanisms and the implications for current clinical practice

Oral contraceptive use and risk of melanoma in premenopausal women

Melanoma has been increasing in white populations. Incidence rates rise steeply in women until about age 50, suggesting oestrogen as a possible risk factor. Oestrogens can increase melanocyte count and melanin content and cause hyperpigmentation of the skin. We examined prospectively the association between oral contraceptive (OC) use and diagnoses of superficial spreading and nodular melanoma among 183 693 premenopausal white women in the Nurses’ Health Study (NHS) and the Nurses’ Health Study II (NHS II) cohorts. One hundred and forty six cases were confirmed in NHS during follow-up from 1976 to 1994, and 106 cases were confirmed in NHS II from 1989 to 1995. Skin reaction to sun exposure, sunburn history, mole counts, hair colour, family history of melanoma, parity, height and body mass index were also assessed and included in logistic regression models. A significant twofold increase in risk of melanoma (relative risk (RR) = 2.0, 95% confidence interval (CI) 1.2–3.4) was observed among current OC users compared to never users. Risk was further increased among current users with 10 or more years of use (RR = 3.4, 95% CI 1.7–7.0). Risk did not appear elevated among past OC users, even among those with longer durations of use, and risk did not decline linearly with time since last use. In conclusion, risk of premenopausal melanoma may be increased among women who are current OC users, particularly among those with longer durations of use. Further research is needed to determine whether low-dose oestrogen pills in particular are associated with an increase in risk and to describe possible interactions between OC use and sun exposure or other risk factors for melanoma. © 1999 Cancer Research Campaig

Description of the novel perchlorate-reducing bacteria Dechlorobacter hydrogenophilus gen. nov., sp. nov. and Propionivibrio militaris, sp. nov.

Novel dissimilatory perchlorate-reducing bacteria (DPRB) were isolated from enrichments conducted under conditions different from those of all previously described DPRB. Strain LT-1T was enriched using medium buffered at pH 6.6 with 2-(N-morpholino)ethanesulfonic acid (MES) and had only 95% 16S rRNA gene identity with its closest relative, Azonexus caeni. Strain MPT was enriched in the cathodic chamber of a perchlorate-reducing bioelectrical reactor (BER) and together with an additional strain, CR (99% 16S rRNA gene identity), had 97% 16S rRNA gene identity with Propionivibrio limicola. The use of perchlorate and other electron acceptors distinguished strains MPT and CR from P. limicola physiologically. Strain LT-1T had differences in electron donor utilization and optimum growth temperatures from A. caeni. Strains LT-1T and MPT are the first DPRB to be described in the Betaproteobacteria outside of the Dechloromonas and Azospira genera. On the basis of phylogenetic and physiological features, strain LT-1T represents a novel genus in the Rhodocyclaceae; strain MPT represents a novel species within the genus Propionivibrio. The names Dechlorobacter hydrogenophilus gen. nov., sp. nov and Propionivibrio militaris sp. nov. are proposed
