Revisiting the Thermal AdS partition function
We rewrite the worldsheet torus partition function of the Thermal AdS CFT by
isolating the boundary parameters. Using this, we show that the spectrum of the
Euclidean BTZ black hole and Lorentzian AdS3 can be extracted -- the latter as
a zero temperature limit. A similar procedure recovers the Lorentzian BTZ
spectrum proposed in an earlier work. We then use our expression to construct a
boundary modular invariant expression as a Poincar\'e series
Antidiabetic Potentials of Various Ethno-Medicinal Plants of Rajasthan
Diabetes Mellitus is a syndrome of disordered metabolism, due to a combination of hereditary and environmental causes, resulting in abnormally high blood sugar levels (hyperglycemia), caused by defects in either insulin secretion or insulin action in the body. Diabetes epidemic is underway. Currently available therapeutic options for non-insulin-dependent diabetes mellitus such as dietary modification, oral hypoglycemics and insulin have a lot potentials to cure diabetes. Now-a-days natural products and herbal medicines have been recommended for the treatment of diabetes. The present paper is an attempt to list of the plants and their preparations used for cure of diabetes with Ethnomedicinal backgrounds with the list of plants experimental or clinically listed from Rajasthan (arid zone) with antidiabetic potentials. The review also include the various preparations which can safely used to cure diabetes in the form of daily diet as plant potentials for future generations. The studies are a move towards awareness towards changing our diet system with potential input of Ethnomedicinal knowledge to cure the incidence of diabetes
Formulation and development of orodispersible sustained release tablet of domperidone
Commercially available domperidone orodispersible tablets (ODT) are intended for immediate release of the drug, but none of them have been formulated for sustained action. The aim of the present research work was to develop and evaluate orodispersible sustained release tablet (ODT-SR) of domperidone, which has the convenience of ODT and benefits of controlled release product combined in one. The technology comprised of developing sustained release microspheres (MS) of domperidone, followed by direct compression of MS along with suitable excipients to yield ODT-SR which rapidly disperses within 30 seconds and yet the dispersed MS maintain their integrity to have a sustained drug release. The particle size of the MS was optimized to be less than 200 μm to avoid the grittiness in the mouth. The DSC thermograms of MS showed the absence of drug-polymer interaction within the microparticles, while SEM confirmed their spherical shape and porous nature. Angle of repose, compressibility and Hausner's ratio of the blend for compression showed good flowability and high percent compressibility. The optimized ODT-SR showed disintegration time of 21 seconds and matrix controlled drug release for 9 h. In-vivo pharmacokinetic studies in Wistar rats showed that the ODT-SR had a prolonged MRT of 11.16 h as compared 3.86 h of conventional tablet. The developed technology is easily scalable and holds potential for commercial exploitation
Fetomaternal outcome in pregnancies complicated by fibroid
Background: Fibromyoma (leiomyoma) is the most common benign tumour of the uterus. Approximately 10% to 30% of women with uterine fibroids developed complications during pregnancy. The aim of the study was planned to ascertain the fetomaternal outcome in pregnancies complicated by fibroid.Methods: A hospital based cross-sectional study was conducted among pregnant women with documented uterine fibroid who was admitted for any complication or delivered in the department of obstetrics and gynaecology, RIMS, Imphal from September 2017 to August, 2019 in the department of obstetrics and gynaecology in collaboration with department of paediatrics, Regional institute of Medical Sciences, Imphal. Detailed clinical history and socio-demographic profile were recorded in pre-designed proforma. General physical examination and systemic examination and obstetrical examination was carried out for the participants.Results: Major proportions was in the age group of 30-39 years (73.9%). Fibroids were more frequent in primigravida (76.1%) followed by P1 (15.2%) and ≥P2 (8.7%). Out of 46 patients 43 (93.5%) delivered by CS (69.76%), NVD (25.58%) and instrumental delivery (4.65%) while 3 patients (6.5%) undergo spontaneous abortions. Most common myoma found in this study was intramural (47.8%) followed by submucous (34.8%) and subserosal (17.4%). Out of 43 deliveries most common complications found was atonic PPH (6.97%) and placenta previa (6.97%) followed by degenerations (2.32%), abruptio placentae (2.32%), malpresentations (2.32%). Out of 43 deliveries 6.9% baby born with low birth weight, IUGR (6.9%), IUFD (4.6%), NICU admission (4.65%) and early neonatal death (2.32%).Conclusions: Pregnancies with fibroids are considered as high-risk pregnancy associated with complications during the antepartum, intrapartum, postpartum period. Pregnant women with myoma can be advised for regular ANC along with TAS for early diagnosis and management of complication
Primary Eye Care in Eastern Nepal.
Purpose: Vision 2020 and the Global Action Plan 2013-2019 prioritise primary eye care (PEC) as an important component of reducing avoidable blindness. Studies in sub-Saharan Africa have demonstrated that current PEC provision is poor. There has been no evaluation of the current practice of PEC among primary health care workers (PHCWs) in Nepal.Methods: A mixed methods descriptive cross-sectional study with semi-structured interviews and focus group discussions (FGDs) was carried out in Eastern Nepal. Government employed PHCWs working at health posts in three districts were invited to take part in a PEC knowledge and skills assessment. Each health post was assessed for ophthalmic equipment and medications. Three focus group discussions and eight semi-structured interviews were carried out with community ophthalmic assistants, PHCWs and a district health manager.Results: 107 PHCWs in 35 health posts took part in the quantitative study. Only 8.4% had received eye care training. 27.1% PHCWs could diagnose a corneal ulcer, 83.2% conjunctivitis, 75.7% cataract and 54.2% ophthalmia neonatorum. Only 14.0% could measure visual acuity, and 5.7% of HPs had a vision chart. Ophthalmic assistants described their concern for the low level of PEC at health posts. PHCWs were keen to receive training and highlighted the need for greater government support in the provision of eye care services.Conclusion: PEC knowledge and skills among PHCWs in eastern Nepal is inadequate to provide quality PEC services. There is a pressing need for PEC training in the region, provision of ophthalmic equipment and greater government support for eye care
Effect of γ-Irradiation on Germination, Growth, Sensitivity and Survivability of Papaya cv. Kesar King
An experiment was laid out in a 4x2 factorial design, with 4 levels of γ-irradiation (0,5,10&15 Krad) and two dates of sowing (15th September and 15th October) on papaya cv. Kesar King. The results indicated that germination percentage, survival percentage and plant growth increased with the increased in γ-irradiation upto 10 Krad. Early sowing of seed (15th September) showed better germination (73%), survival (70%) and plant growth as compared to late sowing (15th October). Interaction between γ-irradiation of 10 Krad and early sowing of seed (15th September) was found superior to all the other treatment combinations to obtain optimum germination percentage, survival percentage and plant growth
Correlation between ultrasonographic and histopathological findings of hysterectomy specimen in patients with abnormal uterine bleeding
Background: AUB is a common and debilitating condition and it is one of the main gynaecological reasons for hysterectomy. Ultrasonography can be as good as histopathology (HPE) in the diagnosis of abnormal uterine bleeding. Hence, our study was conducted to validate the ultrasonographic findings with HPE findings in diagnosis of AUB.Methods: A hospital based cross-sectional analytical study was conducted among 86 patients with abnormal uterine bleeding in the department of Obstetrics and Gynaecology in collaboration with department of Pathology, RIMS, Imphal from September 2017 to March 2019. The clinical history and socio demographic profile were collected using a pre-designed proforma. General physical examination, pelvic examination and ultrasonagraphy was carried out and the hysterectomy specimens were subjected to histopathological examination.Results: Fibromyoma was diagnosed by ultrasound in 62.8% of the patients and it was the common diagnosis in this study. The sensitivity, specificity, positive predictive value, negative predictive value and kappa statistics of USG for diagnosing leiomyoma was 92.9%, 93.3%, 96.3%, 87.5% and 84.9% respectively. The sensitivity, specificity, positive predictive value, negative predictive value and kappa statistics of USG for diagnosing adenomyosis was 53.8%, 98.6%, 87.5%, 92.3% and 62.3% respectively.Conclusions: The study provides an evidence that ultrasonography has good diagnostic accuracy as histopathology in the diagnosis of fibroid in patients with abnormal uterine bleeding. However, as with all the diagnostic procedures, the utility of ultrasound in the diagnosis of adenomyosis is questionable, since it has a low sensitivity amidst good specificity
A study of congenital anomalies in a tertiary care hospital in North East region, India
Background: Congenital anomalies are important cause of morbidity and mortality in newborns and are defined as structural and functional abnormalities including metabolic disorders present at birth. These defects are of prenatal origin resulting from defective embryogenesis or intrinsic abnormalities in the process of development and are associated with various risk factors.Methods: Our study is a cross-sectional study done at Regional Institute of Medical Sciences, Imphal over period of one and half years from May 2016 to October 2017. Aim of study was to find out incidence of congenital anomalies and proportions of different types of congenital anomalies. Outcome was studied in relation to maternal age, religion, parity, gestational age, sex of baby, outcome and birth weight of baby.Results: Total numbers of congenital anomalies were 91 out of 13658 births. Incidence of congenital anomalies was 0.66%. Most common congenital anomaly was cleft lip (17.6%) followed by CTEV (13.2%) and was more common among male term babies. These were most common in 18-24 years of maternal age group (34.1%) followed by 30-34 years (26.4%) and among women of parity P0-P2.Conclusions: Congenital malformations are a major cause of still births and infant mortality. A level II targeted scan should be done at 18-20 weeks to find out anomalies and reduce the prevalence. There should be widespread education in the community regarding the common congenital malformations, their outcomes and possible available modes of treatment.

Topical Chlorhexidine 0.2% versus Topical Natamycin 5% for the Treatment of Fungal Keratitis in Nepal: A Randomized Controlled Noninferiority Trial.
PURPOSE: To investigate if topical chlorhexidine 0.2%, which is low cost and easy to formulate, is noninferior to topical natamycin 5% for the treatment of filamentous fungal keratitis. DESIGN: Randomized controlled, single-masked, noninferiority clinical trial. PARTICIPANTS: Adults attending a tertiary-level ophthalmic hospital in Nepal with filamentous fungal infection confirmed on smear or confocal microscopy. METHODS: Participants were randomly allocated to receive topical chlorhexidine 0.2% or topical natamycin 5%. Primary analysis (intention-to-treat) was by linear regression, using baseline logarithm of the minimum angle of resolution (logMAR) best spectacle-corrected visual acuity (BSCVA) and treatment arm as prespecified covariates. Mixed fungal-bacterial infections were excluded from the primary analysis but included in secondary analyses and secondary safety-related outcomes. The noninferiority margin was 0.15 logMAR. This trial was registered with ISRCTN, number ISRCTN14332621. MAIN OUTCOME MEASURES: The primary outcome measure was BSCVA at 3 months. Secondary outcome measures included perforation or therapeutic penetrating keratoplasty by 90 days. RESULTS: Between June 3, 2019, and November 9, 2020, 354 eligible participants were enrolled and randomly assigned: 178 to chlorhexidine and 176 to natamycin. Primary outcome data were available for 153 and 151 of the chlorhexidine and natamycin groups, respectively. Of these, mixed bacterial-fungal infections were found in 20 cases (12/153 chlorhexidine, 8/151 natamycin) and excluded from the primary analysis. Therefore, 284 patients were assessed for the primary outcome (141 chlorhexidine, 143 natamycin). We did not find evidence to suggest chlorhexidine was noninferior to natamycin and in fact found strong evidence to suggest that natamycin-treated participants had significantly better 3-month BSCVA than chlorhexidine-treated participants, after adjusting for baseline BSCVA (regression coefficient, -0.30; 95% confidence interval [CI], -0.42 to -0.18; P < 0.001). There were more perforations and emergency corneal grafts in the chlorhexidine arm (24/175, 13.7%) than in the natamycin arm (10/173, 5.8%; P = 0.018, mixed infections included), whereas natamycin-treated cases were less likely to perforate or require an emergency corneal graft, after adjusting for baseline ulcer depth (odds ratio, 0.34; 95% CI, 0.15-0.79; P = 0.013). CONCLUSIONS: Treatment with natamycin is associated with significantly better visual acuity, with fewer adverse events, compared with treatment with chlorhexidine. Natamycin remains the preferred first-line monotherapy treatment for filamentous fungal keratitis
