Abstract
Vitamin B12 deficiency is prevalent among individuals globally. Inadequate consumption of B12 rich diet and low bioavailability (due to diet based/physiological factors) are linked to the deficiency of Vitamin B12 inside the body. Bioavailability enhancers augment the bioavailability of an ingested substance (drug/nutrient) thus increasing their concentration inside the body and maximizing their therapeutic benefits. In traditional medicine, Licorice (Glycyrrhiza glabra) finds utility in the treatment of various health conditions. Thus, the present study aimed to examine the potential of ethanolic extract obtained from G. glabra roots to enhance the bioavailability of Vitamin B12. The effect of ethanolic extract of G. glabra (GgEtOH) on intestinal absorption enhancement of B12 was assessed in vitro on Caco-2 and ex-vivo everted gut sac models. The influence of extract on the pharmacokinetics of Vitamin B12 was determined in vivo in Swiss albino mice. GgEtOH significantly enhanced the permeation (Papp) of B12 by 2-5 fold in vitro (25, 50, and 100 μg/ml concentrations) and ex-vivo (250 and 500 μg/ml concentrations). The pharmacokinetic parameters of B12 such as Cmax, AUC, Tmax, etc. were also significantly elevated in vivo upon oral administration of B12 (1 mg/kg dose) in combination with GgEtOH (100 and 1,000 mg/kg dose). These preliminary findings indicate that the ethanolic extract of G. glabra is capable of enhancing the bioavailability of Vitamin B12. To the best of our knowledge, this is the first report to demonstrate herbal extract-mediated enhancement of Vitamin B12 bioavailability through in vitro, ex vivo, and in vivo assays.

Abstract
Background: Non-alcoholic fatty liver disease (NAFLD), mostly diagnosed incidentally, is a rapidly emerging liver disorder. In absence of any specific treatment, current management focuses on theuse of hepatoprotective agents in addition to lifestyle modification and prevention of metabolic syndrome. Several Ayurveda agents have shown promising effects in patients over centuries of use. But this evidence needs to be assessed scientifically through reverse pharmacology approach. A polyingredient Ayurveda drug, Phalatrikadighanvati (PGV) has been selected for this study because of its long history of use and that its individual contents have shown positive results in liver disorders.
Objective: Evaluation of efficacy of Phalatrikadighanvati in patients of non alcoholic fatty liver disease (NAFLD) along with its pharmaceutical and analytical study.
Materials and Methods: The drug shall bepharmaceutically processed and analyzed as per pharmacopoeial standards.Present study has been designed as a randomized placebo controlled double blind clinical trial in two stages. The first stage shall be a pilot study to decide the best effective and safe dose in patients of NAFLD. The pilot study shall include two groups of 10 patients each in a dose of PGV 500mg and 1gm respectively twice a day for 12 weeks. After theselection of thebest dose, RCT will be conducted on that dose in the second stage.It shall be a Phase 2 trial with 60 patients divided equally in two groups.The patients in group one shall be given a dose as per the outcome of the pilot study twice a day and another group shall be administered placebo for a period of 12 weeks.
Results: Efficacy of Phalatrikadi ghan vati will evaluated in terms of subjective and objective parameters using paired and unpaired t-test.
Conclusion: PGV is expected to improve the diagnostic parameters in patients of NAFLD thus proving to be efficacious in managing NAFLDand act as a potent hepatoprotective agent.

Abstract
Plant genetic resources (PGR) are the foundation of agriculture as well as food and nutritional security.
The ICAR-NBPGR is the nodal institution at national level for management of PGR in India under the umbrella
of Indian Council of Agricultural Research (ICAR), New Delhi. India being one of the gene-rich countries faces a
unique challenge of protecting its natural heritage while evolving mutually beneficial strategies for germplasm
exchange with other countries. The Bureaus activities include PGR exploration, collection, exchange, characterization,
evaluation, conservation and documentation. It also has the responsibility to carry out quarantine of
all imported PGR including transgenics meant for research purposes. The multifarious activities are carried out
from ICAR-NBPGR headquarters and its 10 regional stations located in different agro-climatic zones of India. It
has linkages with international organizations of the Consultative Group on International Agricultural Research
(CGIAR) and national crop-based institutes to accomplish its mandated activities. NBPGR collects and acquires
germplasm from various sources, conserves it in the Genebank, characterizes and evaluates it for different traits
and provides ready material for breeders to develop varieties for farmers. ICAR-NBPGR encompasses the National
Genebank Network and at present, the National Genebank conserves more than 0.40 million accessions. NBPGR
works in service-mode for effective utilization of PGR in crop improvement programmes which depends mainly
on its systematic characterization and evaluation, and identification of potentially useful germplasm. NBPGR is
responsible for identifying trait-specific pre-adapted climate resilient genotypes, promising material with disease
resistance and quality traits which the breeders use for various crop improvement programmes. The system has
contributed immensely towards safeguarding the indigenous and introducing useful exotic PGR for enhancing
the agricultural production. Presently, our focus is on characterization of ex situ conserved germplasm and
detailed evaluation of prioritized crops for enhanced utilization; assessment of impact of on-farm conservation
practices on genetic diversity; genome-wide association mapping for identification of novel genes and alleles for
enhanced utilization of PGR; identification and deployment of germplasm/landraces using climate analog data;
validation of trait-specific introduced germplasm for enhanced utilization.
Key words: plant genetic resources; gene banks; wild relatives; biotic and abiotic stresses; marker-assisted
selection.

Abstract
Aims The aim of this study was to compare the rate of perioperative complications following aseptic revision total hip arthroplasty (THA) in patients aged ≥ 80 years with that in those aged < 80 years, and to identify risk factors for the incidence of serious adverse events in those aged ≥ 80 years using a large validated national database. Patients and Methods Patients who underwent aseptic revision THA were identified in the 2005 to 2015 National Surgical Quality Improvement Program (NSQIP) database and stratified into two age groups: those aged < 80 years and those aged ≥ 80 years. Preoperative and procedural characteristics were compared. Multivariate regression analysis was used to compare the risk of postoperative complications and readmission. Risk factors for the development of a serious adverse event in those aged ≥ 80 years were characterized. Results The study included 7569 patients aged < 80 years and 1419 were aged ≥ 80 years. Multivariate analysis showed a higher risk of perioperative mortality, pneumonia, urinary tract infection and the requirement for a blood transfusion and an extended length of stay in those aged ≥ 80 years compared with those aged < 80 years. Independent risk factors for the development of a serious adverse event in those aged ≥ 80 years include an American Society of Anesthesiologists score of ≥ 3 and procedures performed under general anaesthesia. Conclusion Even after controlling for patient and procedural characteristics, aseptic revision THA is associated with greater risks in patients aged ≥ 80 years compared with younger patients. This is important for counselling and highlights the need for medical optimization in these vulnerable patients. Cite this article: Bone Joint J 2018;100-B:143–51.

Abstract
BACKGROUND Direct to physician advertisements and direct to consumer advertisement (DTCA) is a well-known marketing strategy of pharmaceutical companies. Studies from the West and also from the Indian sub-continent revealed several lacunae in such advertisements. OBJECTIVES The present study was carried out to understand the international and national scenario regarding the lacunae in drug advertisements and the opinion of both physicians and patients regarding DTCA. METHODS The present study was conducted after obtaining approval from the institutional ethics committee. Warning letters (WLs) issued to pharmaceutical companies by United States Food and Drug Administration (USFDA) and Therapeutic Goods Administration (TGA) due to discrepancies in the advertisements were analyzed for reasons that were grouped into one of the following categories: overstatement of efficacy; unapproved indication; lack of adequate directions to use; omission of adverse effects; misleading claims; advertisement made for an unapproved drug (investigational new product). Drug advertisements in Current Index of Medical Specialties (CIMS) April-July 2014 issue was also analyzed for lacunae depending on categories as mentioned above. Physicians and patients in a tertiary care medical college and hospital were administered a validated questionnaire exploring their views about crucial aspects of DTCA. Descriptive statistics was used for each of the categories. RESULTS A total of 93 WLs issued by USFDA and 36 by TGA were assessed. Majority of the WLs by USFDA were issued for omission of adverse effects (61/93, 65.6%) followed by misleading claims (54/93, 58.1%). Similarly, WLs by TGA were also mainly issued for the presence of misleading claims (35/36, 97.2%) followed by overstatement of efficacy (26/36, 72.2%) and CIMS evaluation had revealed that 78/92 (84.8%) advertisements omitted adverse effects, 20/92 (21.7%) had misleading claims, 9/92 (9.8%) had unapproved indications and 7/92 (7.6%) overstated the efficacy. With regard to the opinion regarding DTCA, 69.9% physicians had a patient discussing DTCA that was clinically inappropriate. One hundred (64.5%) out of 155 physicians opined that DTCA encourage patients to attend physicians regarding preventive healthcare. On the contrary, 82/155 (52.9%) physicians felt that DTCA would damage the same. Similarly, 69 out of the total 100 patients felt that drug advertisements aid them to have better discussions with their treating physicians. Surprisingly, a large majority (91/100) were of the opinion that only safe drugs are allowed to be advertised. CONCLUSION To conclude, from the findings of this study both the physicians and patients should be cautious and not overzealous while dealing with drug advertisements or promotional literature. More stringent scrutiny and issue of WLs or blacklisting of indulging pharmaceutical companies are mandatory by the regulatory agency to contain the same.

Abstract
BACKGROUND & OBJECTIVES Screening of crude extracts of plants facilitates the establishment of highly effective extract for mosquito control. This practice should be preferred before in depth study of plant extracts rather than spending much efforts and energy in detailed examinations for practically ineffective extracts. In this study, leaf powders of four weed plants were used for the quick screening of effective plant extract as larvicide against III instar larvae of Aedes albopictus Skuse. At the same time, effect of different seasons on the larvicidal efficacy of plants and selection of proper solvents for further investigation were also studied. METHODS Leaves of Vernonia cinerea, Prosopis juliflora, Hyptis suaveolens and Malvastrum coromandelianum plants were collected in summer, winter and rainy seasons from Madhya Pradesh region (India). To assess the larvicidal efficacy the suspensions of leaf powders in different solvents (isopropanol, methanol, acetone, dimethylsulfoxide and water) were used for larvicidal bioassay. The mortality counts were made after 24 h and the LC50 and LC90 values were calculated. RESULTS Results showed that leaf powder of V. cinerea in acetone collected during summer showed highest efficacy with LC50 value of 0.22 g/l and LC90 of 0.96 g/l followed by methanolic solution of P. juliflora with LC50 of 0.44 g/l and LC90 value as 1.85 g/l. Amongst all solvents, leaf powder in acetone; while among seasons, summer collected plant materials were found to be more effective larvicides as compared to others. INTERPRETATION & CONCLUSION Summer and winter collected leaves of V. cinerea and P. juliflora dissolved in the solvents of medium polarity range showed significant larval toxicity and thus suggests a detailed study on these plants as potential larval control agents.
