Abstract
This research compares the momentum, thermal energy, mass diffusion and entropy generation of two shear thinning nanofluids in an angled micro-channel with mixed convection, nonlinear thermal radiation, temperature jump boundary condition and variable thermal conductivity effects. The [Formula: see text] approach was used to solve the Buongiorno nonlinear governing model. The effect of different parameters on the flow, energy, concentration, and entropy generating fields have been graphically illustrated and explained. The hyperbolic tangent nanoliquid has a better velocity than the Williamson nanofluid. The Williamson nanofluid has higher thermal energy and concentration than the hyperbolic tangent nanoliquid in the microchannel. The Grashof number, both thermal and solutal, increases the fluid flow rate throughout the flow system. The energy of the nanoliquid is reduced by the temperature jump condition, while the energy field of the nanoliquid is enhanced by the improving thermal conductivity value. The nanoliquids concentration rises as the Schmitt number rises. The irreversibility rate of the channel system is maximized by the variable thermal conductivity parameter.

Abstract
PURPOSE/OBJECTIVE(S) Radiation toxicity to the bulboclitoris has not been previously investigated. This retrospective cohort study aims to report sexual side effects of patients who underwent radiotherapy for tumors involving the lower vagina, periurethra, and bulboclitoris (BC). MATERIALS/METHODS Patients treated between 2017- 2022 for gynecologic cancer involving the low vagina were included. The high-risk clinical target volume (HR-CTV), bladder, rectum, and urethra were contoured on patient imaging during initial treatment planning. The BC was retrospectively contoured using T2 MRI sequences fused to the pre-treatment and brachytherapy CT simulation. Superiorly, the BC was defined as inferior to the pubic symphysis and attached to the suspensory ligament of the clitoris. Laterally, the crura extend on either side of the corpus. Inferiorly, the vestibular bulbs flank the urethra and vagina on either side, extending posteriorly to mid-vagina. Dosimetric data for the BC, vaginal morbidity using the CTCAE 4.0 for vaginal stenosis, and pain scoring of the BC were obtained via chart review. RESULTS Patients underwent external beam radiotherapy (IMRT) to the pelvis and bilateral inguinal region (45 Gy in 25 fractions) followed by High Dose Rate Ir-192 interstitial brachytherapy in 5 fractions for a total dose of 25 Gy (22.5 - 27.5 Gy). Patients had a median age of 65 years (49-73) with tumors located in the lower vagina, near the BC and urethra. At the time of brachytherapy, in order to cover the HR-CTV, interstitial brachytherapy needles were placed within the BC structure with 58% (33% - 77%) of total interstitial needles placed within the bulbs of the BC. The mean pre-treatment volume of the BC was 16.6 cc (11.9 - 20.9 cc) and at brachytherapy was 12.66 cc (7.3 - 22.1 cc) with Table 1 summarizing radiation doses. At a median follow up of 19.6 months, all patients had a complete local response, with one patient deceased of metastatic disease. In the acute period, all patients reported severe pain in the clitoral glans region and dysuria that completely resolved after 2 years. Grade 1-2 vaginal stenosis occurred in all patients despite vaginal dilator usage. One patient reported decreased clitoral sensitivity and inability to achieve clitoral-mediated orgasm 5 months after radiotherapy. CONCLUSION This study demonstrates that the BC receives a significant radiation dose during vaginal brachytherapy treatment which can cause clitoral pain and dysfunction. Further studies are needed to evaluate the dose response of the BC as well as explore methods to spare the organ during radiation therapy in order to minimize toxicity and preserve sexual function.

Abstract
Pearl millet is a nutrient dense and gluten free cereal, however it's flour remains underutilized due to the onset of rancidity during its storage. To the best of our knowledge, processing methods, which could significantly reduce the rancidity of the pearl millet flour during storage, are non-existent. In this study, pearl millet grains were subjected to a preliminary hydro-treatment (HT). Subsequently, the hydrated grain-wet flour have undergone individual and combined thermal treatments viz., hydrothermal (HTh) and thermal near infrared rays (thNIR). Effects of these thermal treatments on the biochemical process of hydrolytic and oxidative rancidity were analyzed in stored flour. A significant (p < 0.05) decrease in the enzyme activities of lipase (47.8%), lipoxygenase (84.8%), peroxidase (98.1%) and polyphenol oxidase (100%) in HT-HTh-thNIR treated flour compared to the individual treatments was documented. Upon storage (90 days), decline of 67.84% and 66.4% of free fatty acid and peroxide contents were observed in flour under HT-HTh-thNIR treatment without altering starch and protein digestibility properties. HT-HTh treated flour exhibited the highest (7.6%) rapidly digestible starch, decreased viscosity and increased starch digestibility (67.17%). FTIR analysis of HT-HTh treated flour divulged destabilization of short-range ordered crystalline structure and altered protein structures with decreased in vitro digestibility of protein. Overall, these results demonstrated the effectiveness of combined thermal treatment of HT-HTh-thNIR in reducing rancidity and preserving the functional properties of the stored flour.

Abstract
Ionising radiation has been an important modality in cancer treatment and its value is immense when surgical intervention is risky or might debilitate/adversely affect the patient. However, the beneficial effect of radiation modality is negated by the damage to the adjacent healthy tissue in the field of radiation. Under these situations, the use of radioprotective compounds that can selectively protect normal tissues against radiation injury is considered very useful. However, research spanning over half a century has shown that there are no ideal radioprotectors available. The United States Food and Drug Administration (FDA or USFDA) approved amifostine or WR-2721 (Walter Reed-2721) [chemically S-2-(3-aminopropyl-amino) ethyl phosphorothioic acid] is toxic at their optimal concentrations. This has necessitated the need for agents that are safe and easily acceptable to humans. BACKGROUND Dietary agents with beneficial effects like free radical scavenging, antioxidant and immunomodulatory effects are recognized as applicable and have been investigated for their radioprotective properties. Studies in these lines have shown that the fruits of Aegle marmelos (stone apple or bael), Emblica officinalis or Phyllanthus emblica(Indian gooseberry/amla), Eugenia jambolana or Syzygium jambolana (black plum / jamun), Mangifera indica (mango) and Grewia asiatica (phalsa or falsa) that are originally reported to be indigenous to India have been investigated for their usefulness as a radioprotective agent. OBJECTIVE The objective of this review is to summarize beneficial effects of the Indian indigenous fruits stone apple, mango, Indian gooseberry, black plum, and phalsa in mitigating radiation-induced side effects, emphasize the underlying mechanism of action for the beneficial effects and address aspects that merit detail investigations for these fruits to move towards clinical application in the near future. METHODS The authors data mined in Google Scholar, PubMed, Embase, and the Cochrane Library for publications in the field from 1981 up to July 2020. The focus was on the radioprotection and the mechanism responsible for the beneficial effects, and accordingly, the articles were collated and analyzed. RESULTS This article emphasizes the usefulness of stone apple, mango, Indian gooseberry, black plum, and phalsa as radioprotective agents. From a mechanistic view, reports are suggestive that the beneficial effects are mediated by triggering free radical scavenging, antioxidant, anti-mutagenic and anti-inflammatory effects. CONCLUSION For the first time, this review addresses the beneficial effects of mango, Indian gooseberry, black plum, stone apple and phalsa as radioprotective agents. The authors suggest that future studies should be directed at understanding the selective radioprotective effects with tumor-bearing laboratory animals to understand their usefulness as radioprotective drug/s during radiotherapy and as a food supplement to protect people getting exposed to low doses of radiation in occupational settings. Phase I clinical trial studies are also required to ascertain the optimal dose and the schedule to be followed with the standardized extract of these fruits. The most important aspect is that these fruits are a part of the diet, have been consumed since the beginning of mankind, are non-toxic, possess diverse medicinal properties, have easy acceptability all of which will help take research forward and be of benefit to patients, occupational workers, agribased sectors and pharma industries.

Abstract
The existing work unveils the mixed convection squeezed flow of MHD hybridized nanoliquid amid two plates of the channel that is rotating vertically depending upon time. The fluid is sucked/injected through the channel extremes. The hybrid nanofluid anticipated here is composed of Graphene
oxide and Molybdenum disulphide with the hybrid base fluid comprised of water and ethylene glycol. The scrutiny is carried out in the presence of thermal radiation and heat source. The acquired equations are numerically computed with the aid of Runge Kutta Fehlberg 4–5th order method.
The entropy behavior and Bejan number are examined utilizing graphs. The novelty of the work lies in perceiving which shape of nanoparticle has better tendency in escalating the heat transport and whip up the efficiency of the channel. The flow repercussion so obtained are emphasized for both
hybrid and nano phase. On enlarging squeezing parameter, velocity escalates whereas for large values of rotating parameter velocity diminishes. The temperature is highest for blade structured and least for brick shaped nanoparticles. Heat generation/absorption parameter plays a crucial role
in controlling the heating and cooling process. Higher value of this parameter augments the thermal profile. Bejan number is least for blade structured nanoparticles.

Abstract
BACKGROUND In the treatment of head and neck cancer (HNC), ionizing radiation is an important modality in achieving curative objectives. However, the effective use of radiation is compromised by the side effects resulting from the damage to the adjacent normal tissue. Preclinical studies carried out in the recent past have shown that the age old dietary agent honey, which also possess myriad medicinal use is beneficial in mitigating diverse radiation-induced side effects like mucositis, xerostomia, fatigue, weight loss and to promote healing of refractory wounds. OBJECTIVE The objective of this memoir is to review the beneficial effects of honey in mitigating radiation-induced side effects in HNC and to emphasize on the underlying mechanism of action for the beneficial effects Methods: Two authors searched Google Scholar, PubMed, Embase, and the Cochrane Library for publications up to December 2019 to assess the ability of honey in reducing the severity of radiation-induced ill effects in the treatment of HNC. Subsequently, the adjunct pharmacological effects and mechanism/s responsible were also searched for and appropriately used to substantiate the underlying mechanism/s of action for the beneficial effects. RESULTS The existing data is suggestive that honey is beneficial in mitigating the radiation-induced mucositis, xerostomia, healing of recalcitrant wounds in radiation exposed regions and multiple pathways mediate the beneficial effects especially, free radical scavenging, antioxidant, wound healing, anticancer, analgesic, anti-inflammatory, anabolic, anti-fatigue and anti-anaemic effects that add additional value to the use of honey as an adjunct in cancer therapy. CONCLUSION For the first time this review addresses the underlying pharmacological effects related to the beneficial effects of honey in radiation-induced damage, and attempts at emphasizes the lacunae that need further studies for optimizing the use of honey as an adjunct in radiotherapy of HNC. The authors suggest that future studies should be directed at understanding the detail molecular mechanisms responsible for the beneficial effects using validated cell culture and animal models of study. Large multi centric clinical trials with standardised honey is also needed to understand the clinical use of honey.

Abstract
OBJECTIVES To describe the clinical and ultrasound characteristics of adnexal torsion. METHODS This was a retrospective study. From the operative records of the eight participating gynecological ultrasound centers, we identified patients with a surgically confirmed diagnosis of adnexal torsion, defined as surgical evidence of ovarian pedicle, paraovarian cyst and/or Fallopian tube twisted on its own axis, who had undergone preoperative ultrasound examination by an experienced examiner, between 2008 and 2018. Only cases with at least two available ultrasound images and/or videoclips (one grayscale and one with Doppler evaluation) were included. Clinical, ultrasound, surgical and histological information was retrieved from each patient's medical record and entered into an Excel file by the principal investigator at each center. In addition, two authors reviewed all available ultrasound images and videoclips of the twisted adnexa, with regard to the presence of four predefined ultrasound features reported to be characteristic of adnexal torsion: (1) ovarian stromal edema with or without peripherally displaced antral follicles, (2) the follicular ring sign, (3) the whirlpool sign and (4) absence of vascularization in the twisted organ. RESULTS A total of 315 cases of adnexal torsion were identified. The median age of the patients was 30 (range, 1-88) years. Most patients were premenopausal (284/314; 90.4%) and presented with acute or subacute pelvic pain (305/315; 96.8%). The surgical approach was laparoscopic in 239/312 (76.6%) patients and conservative surgery (untwisting with or without excision of a lesion) was performed in 149/315 (47.3%) cases. According to the original ultrasound reports, the median largest diameter of the twisted organ was 83 (range, 30-349) mm. Free fluid in the pouch of Douglas was detected in 196/275 (71.3%) patients. Ovarian stromal edema with or without peripherally displaced antral follicles was reported in the original ultrasound report in 167/241 (69.3%) patients, the whirlpool sign in 178/226 (78.8%) patients, absent color Doppler signals in the twisted organ in 119/269 (44.2%) patients and the follicular ring sign in 51/134 (38.1%) patients. On retrospective review of images and videoclips, ovarian stromal edema with or without peripherally displaced antral follicles (201/254; 79.1%) and the whirlpool sign (139/153; 90.8%) were the most commonly detected features of adnexal torsion. CONCLUSION Most patients with surgically confirmed adnexal torsion are of reproductive age and present with acute or subacute pain. Common ultrasound signs are an enlarged adnexa, the whirlpool sign, ovarian stromal edema with or without peripherally displaced antral follicles and free fluid in the pelvis. The follicular ring sign and absence of Doppler signals in the twisted organ are slightly less common signs. Recognizing ultrasound signs of adnexal torsion is important so that the correct treatment, i.e. surgery without delay, can be offered. Copyright © 2020 ISUOG. Published by John Wiley & Sons Ltd.

Abstract
Objectives: Nutritional status is the sensitive indicator of a child's health, and they constitute the most vulnerable segment of any community. Undernutrition causes a great deal of physical, mental, and emotional suffering. Anganwadi is a part of the Integrated Child Development Services program started to combat child hunger and child malnutrition. This study was undertaken to assess the nutritional status of the children (6 months–6 years) in Anganwadis and determine the sociodemographic factors associated with malnutrition and to assess their dietary intake. Materials and Methods: This cross-sectional study was undertaken among 580 children in Anganwadis in the urban field practice area of a Medical college in Tumkur. Results: In this study, the overall prevalence of underweight, stunting, and wasting was found to be 34.14%, 45.52%, and 35.52%, respectively. Age, socioeconomic status, immunization status, religion, and mother's education was associated with undernutrition. The deficient intake of calorie and protein was seen in 90% and 64.8% of the study participants. Conclusion: The present study showed that there is still a high prevalence of undernutrition among the Anganwadi children aged 6–72 months. Socioeconomic factors have a significant role in child nutrition, which manifests itself as poor development.

Abstract
Purpose To evaluate the effect of intravitreal triamcinolone acetonide on visual acuity and macular thickness using optical coherence tomography (OCT) in macular edema associated with various retinal vascular disorders. Methods This prospective nonrandomized clinical interventional study included 81 eyes (76 patients) comprised of Group I, 57 eyes (51 patients) with diabetic macular edema; Group II, 10 eyes (10 patients) with branch retinal vein occlusion; and Group III, 13 eyes (13 patients) with central retinal vein occlusion. All eyes received an intravitreal injection of 4 mg triamcinolone acetonide (with the solvent) in the operation theater under sterile conditions. Results Mean preinjection central macular thickness was 531.84±132 μm in Group I, 458.4±149 μm in Group II, and 750.81±148 μm in Group III. All groups showed a statistically significant decrease in mean central macular thickness at 1 month (300.7±119 μM in Group I, 218.2±99 μm in Group II, and 210.5 ±56 μm in Group III) and 3 months (253.19±109 μm in Group I, 187±47 μm in Group II, and 182±50 μm in Group III) after injection (p<0.05). Mean follow-up was 22±2.4 weeks. Mean visual acuity increased in all three groups (preoperative visual acuity in Group I, 1.2±0.4 logMAR units; Group II, 1.24±0.5 logMAR units; Group III, 1.1 ±0.4 logMAR units; 1 month postinjection in Group I, 0.88±0.3 logMAR units; Group II, 0.67±0.3 logMAR units; Group III, 0.86±0.4 logMAR units; 3 months postinjection in Group I, 0.84±0.4 logMAR units; Group II, 0.59±0.3 logMAR units; Group III, 0.82±0.5 logMAR units) (p<0.05). Forty-one eyes completed 6 months and 20 eyes completed 9 months follow-up. Twelve of 20 (41%) eyes in Group I, 2/6 (33%) eyes in Group II, 3/6 (50%) eyes in Group III, and 8/15 (53%) eyes in Group I, 1/3 (33%) eyes in Group II, and 2/2 (100%) eyes in Group III developed recurrence of macular edema with worsening of visual acuity at 6 and 9 months, respectively. Thirty-three (40.7%) eyes developed IOP elevation (at least one reading > 24 mmHg). One eye developed infective endophthalmitis. Conclusions Intravitreal injection of triamcinolone acetonide may be considered as an effective treatment for reducing macular thickening due to diffuse diabetic macular edema, venous occlusion associated macular edema, and may result in increase in visual acuity at least in the short term. Further follow-up and analysis is required to demonstrate its long-term efficacy.

Abstract
Purpose To evaluate the short-term efficacy and safety of intravitreal bevacizumab in myopic choroidal neovascularization (mCNV). Methods In this noncomparative, consecutive, interventional case series, 12 eyes of 11 patients with mCNV without any previous treatment were included. Patients received intravitreal bevacizumab (1.25 mg/0.05 mL) at baseline and at 4 weeks interval, if optical coherence tomography (OCT) showed presence of intraretinal edema, subretinal fluid, and/or pigment epithelial detachment. Patients were followed up for a minimum of 6 months and changes in best-corrected visual acuity, central macular thickness (CMT) on OCT, angiographic characteristics, and complications were assessed. Results The mean refractive error was −11.25 diopters. At 6 months the mean best-corrected visual acuity (BCVA) improved from 20/235 (median 20/235) to 20/71 (median 20/80) (p=0.01). The mean CMT was reduced from 403 μm (median 365 μm) to 229 μm (median 239 μm) (p=0.002). At final visit 9 eyes (75%) had an improvement of BCVA of three lines or more, and only 1 eye (8%) lost two lines. No significant ocular or untoward systemic side effects were observed. Conclusions In this small series short-term results suggest that intravitreal bevacizumab (1.25 mg/0.05 mL) is safe, effective, and well tolerated in patients with choroidal neovascularization due to high myopia. Further evaluation in large series with longer follow-up is needed to confirm long-term efficacy and safety in such cases.

Abstract
Nocturnal enuresis is a common problem affecting school-aged children worldwide. Although it has significant impact on child's psychology, it is always under-recognized in India and considered as a condition which will outgrow with advancing age. Nocturnal enuresis classified as primary or secondary and monosymptomatic or nonmonosymptomatic. Factors that cause enuresis include genetic factors, bladder dysfunction, psychological factors, and inappropriate antidiuretic hormone secretion, leading to nocturnal polyuria. Diagnosis consists of detailed medical history, clinical examination, frequency-volume charts, and appropriate investigations. The frequency-volume chart or voiding diary helps in establishing diagnosis and tailoring therapy. The first step in treating nocturnal enuresis is to counsel the parents and the affected child about the condition and reassure them that it can be cured. One of the effective strategies to manage enuresis is alarm therapy, but currently, it is not easily available in India. Desmopressin has been used in the treatment of nocturnal enuresis for close to 50 years. It provides an effective and safe option for the management of nocturnal enuresis. This review covers the diagnosis and management of nocturnal enuresis and introduces the concept of “bedwetting clinics” in India, which should help clinicians in the thorough investigation of bedwetting cases.

Abstract
The radioprotective effect of a hydroalcoholic extracted material from the fruit of Aegle marmelos (AME) was studied in mice exposed to different doses of γ radiation. The optimum dose for radioprotection was determined by administering 0, 5, 10, 20, 40, or 80 mg/kg body weight of AME intraperitoneally (ip) once daily, consecutively for 5 days before exposure to 10 Gy of γ radiation. A total of 20 mg/kg of AME for 5 consecutive days before irradiation was found to afford maximum protection as evidenced by the highest number of survivors after 30 days postirradiation. Animals from all groups were monitored for 30 days postirradiation for development of symptoms of radiation sickness and mortality. Treatment of mice with AME before exposure to different doses of γ radiation reduced the severity of symptoms of radiation sickness and mortality with all exposure doses. This was accompanied by an increase in number of survivors in the AME + irradiation group when compared with the concurrent sterile physiological saline (SPS) + irradiation group. AME pretreatment protected mice against the gastrointestinal as well as bone marrow deaths, as evidenced by the greater number of survivors on day 10 or 30, respectively. LD50/30 was found to be 8.2 Gy for the SPS + irradiation group, while it was 8.8 Gy for AME + irradiation. The dose-reduction factor (DRF) was found to be 1.1 for AME + irradiation group. The acute toxicity study of AME showed that it was nontoxic up to a dose of 6 g/kg body weight, the highest drug dose that could be administered. Irradiation of animals resulted in a dose-dependent elevation in lipid peroxidation in liver, kidney, stomach, and intestine of mice. Conversely, GSH concentration declined in a dose-dependent manner. Treatment of animals with AME before irradiation caused a significant decrease in the lipid peroxidation accompanied by a significant elevation in the GSH concentration in liver, kidney, stomach, and intestine of mice determined at 31 days postirradiation.

Abstract
The frequency of micronucleated polychromatic (MPCE), normochromatic erythrocytes (MNCE), and polychromatic/normochromatic erythrocyte ratio (PCE/NCE), was studied in the bone marrow of mice orally administered with 0, 200, 225, 250, 275 and 300 mg/kg body weight of hydroalcoholic leaf extract of Aegle marmelos (AME). Treatment of mice with AME, once daily for 5 consecutive days, before exposure to 2 Gy resulted in a significant decline in the frequency of MPCE when compared to the non-drug-treated irradiated control. The greatest reduction in MPCE was observed for 250 mg/kg body weight AME, accompanied by the highest polychromatic erythrocyte to normochromatic erythrocyte ratio, in comparison with the non-drug-treated irradiated control. Therefore, further studies were carried out using this dose of AME, where the animals were administered with 250 mg/kg body weight of AME before exposure to 0, 0.5, 1, 2, 3 and 4 Gy of γ-radiation and evaluated at 12, 24, 36 and 48 hours post-irradiation. Whole body irradiation of mice to different doses of γ-radiation resulted in a dose-dependent increase in the frequency of MPCE at all post-irradiation times. Treatment of 250 mg/kg AME orally (p.o.) before irradiation significantly reduced the frequency of MPCE at all post-treatment times. The frequency of MPCE increased with time, reached a peak level at 24 hours, and declined thereafter. The occurrence of MNCE has also shown a pattern similar to MPCE, except that the MNCE frequency reached a peak level by 48 hours. The AME significantly reduced the frequency of MNCE at all post-irradiation times, when compared to the non-drug-treated irradiated group. Treatment of mice with AME before exposure to different doses of γ-radiation resulted in the inhibition of a radiation-induced decline in the PCE/NCE ratio, when compared with the concurrent irradiated controls. To gain insight into the mechanism of action, AME was tested for its antioxidant effects in cell-free chemical systems using H2O 2/FeSO4 to generate hydroxyl (◦OH) radicals, which were measured by a fluorescent probe, 2V, 7V-dichlorofluorescin diacetate (DCFH/DA). Xanthine/xanthine oxidase was used to generate superoxide (O2◦-) anion radical, which was measured by a fluorescent probe dihydroethidium (DHE). AME significantly reduced fluorescence in a concentration dependent manner, indicating its efficacy to scavenge free radicals. Our results demonstrate that one of the mechanism of reduction in the radiation-induced DNA damage in mice bone marrow by AME may be due to scavenging of free radicals and elevation in the antioxidant status, as previously reported.

Abstract
OBJECTIVE To evaluate the potential effect of bamboo seed oil in decreasing the major metabolic symptoms associated with letrozole-induced polycystic ovarian disease using female rat model. MATERIALS AND METHODS A new method of microwave-assisted extraction was developed. Female rats were grouped into four with six animals each. All rats were daily administered with letrozole (1 mg/kg b.wt.) for 21 days except control, and during this period, changes in estrous cycle were observed. After letrozole treatment, Group 2 was considered negative control, Groups 3 and 4 were treated orally with bamboo oil, 0.5 ml/kg b.wt. and 1 ml/kg b.wt., respectively, for 3 weeks (five consecutive estrus cycles). Various parameters such as estrus cycle, blood sugar level, lipid profile, and weights of reproductive system were determined. The characteristics of cystic ovaries were evaluated by histopathological studies. RESULTS The isolated bamboo oil restored estrus cyclicity showed hypoglycemic and hypolipidemic effects. 1 ml/kg b.wt. of bamboo oil showed a marked glucose reduction from 254.04 ± 2.08 to 92.6 ± 1.63, and levels of total cholesterol, very low-density lipoprotein, triglyceride were reduced from 186.45 ± 2.28, 30.07 ± 2.36, 100.36 ± 2.35 to 152.14 ± 2.63, 25.94 ± 1.66, 93.32 ± 1.09, respectively. Histopathological results showed the presence of ovulation and recovery from cystic ovaries. CONCLUSION A novel and promising drug was isolated in the treatment and maintenance of various metabolic symptoms associated with polycystic ovary disease.

Abstract
INTRODUCTION The results of surgical outcomes of 20 gauge pars plana vitrectomy in Eales' disease are available in the scientific literature. However, all these studies have been done using the 20 gauge vitrectomy systems and most studies have been conducted in a retrospective manner. OBJECTIVE To evaluate the outcomes and safety of 23 gauge vitrectomy in complications of Eales' disease. MATERIALS AND METHODS STUDY DESIGN Consecutive interventional case series. PARTICIPANTS Seventy-six eyes of 72 nonconsecutive patients undergoing 23-gauge vitrectomy for complications of Eales' disease were enrolled. The participants were followed up for a minimum of one year. INTERVENTION The participants underwent a complete demographic, medical and ophthalmic evaluation. A 23-gauge vitrectomy was performed. Endotamponade was used when necessary. Perioperative and postoperative events were recorded. Primary outcome measures were visual acuity and complications arising due to surgery. RESULTS Indication for surgery was non-clearing vitreous hemorrhage in 89.4% (68/76) and secondary retinal detachment in 10.6% (8). Visual acuity improved from Log Mar 1.80 ± 0.19 units preoperatively to Log Mar 0.47±0.59. Best-corrected visual acuity equivalent to Snellen 6/9 was achieved in 77. 6% of eyes. . Surgical failure was seen in 6.5% cases. Four cases were lost due to progression to neovascular glaucoma and 1 case was lost to severe residual retinal detachment. Iatrogenic portside retinal breaks occurred in 3.9% (3), post-vitrectomy retinal detachment 2.6% ( 2), hypotony 1.3% (1) and cataract in 38.1% (28) cases. CONCLUSION 23-gauge sutureless vitrectomy in patients with Eales' disease is a safe and effective technique with acceptable level of risk and complications.

Abstract
CONTEXT Asthma is multifaceted disease where many targets contribute towards its development and progression. Among these, adenosine receptor subtypes play a major role. OBJECTIVE MCD-KV-10, a novel thiazolo-thiophene was designed and evaluated pre-clinically for its implication in management of asthma. MATERIALS AND METHODS This compound showed good affinity and selectivity towards A(2A)/A3 adenosine receptor (AR) subtypes. Furthermore, MCD-KV-10 was evaluated for in vitro lipoxygenase inhibition activity; in vivo mast cell stabilization potential and in vivo anti-asthmatic activity was done in ovalbumin-induced airway inflammation model in guinea pigs. RESULTS The compound showed good (>57%) inhibition of lipoxygenase enzyme and also effectively protected mast cell degranulation (>63%). The compound showed good anti-asthmatic activity as inferred from the in vivo studies. DISCUSSION These results indicate that MCD-KV-10 has an inhibitory effect on airway inflammation. CONCLUSION Though, we have identified a potential candidate for management of asthma, further mechanistic studies are needed.

Abstract
Atrial fibrillation is a common arrhythmia that increases the risk of stroke by 4.5 times. Anticoagulant/antithrombotic therapy in atrial fibrillation has been inconsistent and inappropriate. Warfarin enjoyed the monopoly of being the primary medication used to reduce the risk of thromboembolic events. Warfarin has many limitations in its use as an ideal anticoagulant. To overcome this difficulty, now there are two main alternative groups to warfarin namely, direct thrombin inhibitors (ximelagatran and dabigatran) and factor Xa inhibitors (apixaban, rivaroxaban, edoxaban, etc.). The advantages of the newer anticoagulants over the conventional warfarin are numerous. There are three landmark trials which have shown some light to the path of newer anticoagulant era, which include the following: RE-LY, ROCKET AF and ARISTOTLE. Head to head comparison of warfarin with newer anticoagulants showed the superiority of newer anticoagulants over warfarin in terms of efficacy and favorable side effect profile. After few decades of using warfarin, it's high time to enter into the era of newer anticoagulants and bid adieu to warfarin.

Abstract
Aegle marmelos, commonly known as Bael and belonging to the family Rutaceae is an important medicinal plant in the traditional Indian system of medicine, the Ayurveda. The extract prepared by boiling the bark, leaves or roots in water is useful as laxative, febrifuge, and expectorant. The extract is also useful in ophthalmia, deafness, inflammations, catarrh, diabetes, and asthmatic complaints. The fruits are used in treating diarrhea, dysentery, stomach ache, and cardiac ailments. Scientific studies have validated many of Bael’s ethnomedicinal properties and its potential antimicrobial effects, hypoglycemic, astringent, antidiarrheal, antidysenteric, demulcent, analgesic, anti-inflammatory, antipyretic, wound-healing, insecticidal, and gastroprotective properties. In addition, studies have also shown that Bael and some of the Bael phytochemicals possess antineoplastic, radioprotective, chemoprotective, and chemopreventive effects, properties efficacious in the treatment and prevention of cancer. For the first time, the current review summarizes the results related to these properties and emphasizes aspects that require further investigation for Bael’s safe and effective use in the near future.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Ayurveda, derives from the Sanskrit words Ayus (life) and Veda (knowledge) is the most ancient system of traditional medicine of the world. It has been practiced in Indian peninsula since 5000 BC to offer natural ways to treat diseases and to promote healthcare. METHODOLOGY We reviewed the literature on the history, principles and current status of Ayurveda. The data have been presented systematically including the initiatives from Government of India. Several aspects of administrative management, education, teaching and related aspects for promotion and development of Ayurveda and other Indian systems of traditional medicine have been discussed. RESULTS This paper reviews on different aspects of development of Ayurveda. Presently, there are 2420 hospitals with about 42271 beds, 15017 dispensaries, 429246 registered practitioners, more than 320 educational institutions, 7699 drug-manufacturing units to promote Ayurveda into the health care delivery system in the country. Ayurvedic Pharmacopoeia of India is the official document for single Ayurvedic drugs (540 monographs) and different formulations (152 monographs). Several aspects in this regard for development of Ayurveda have been discussed. CONCLUSION Considering the widespread use and popularity of Ayurveda worldwide, administrative management and infrastructure facilities, indigenous practices and standards for quality control and it's evaluation have been highlighted. In India, all such efforts for integration of Ayurveda provide potential role in the health care benefits.

Abstract
BACKGROUND & OBJECTIVES The discrimination between the Staphylococcus epidermidis colonizing the deep seated indwelling devices and those which are mere commensals has always been a challenge for the clinical microbiologist. This study was aimed to characterize the S. epidermidis isolates obtained from device related infection for their phenotypic and molecular markers of virulence and to see whether these markers can be used to differentiate the pathogenic S. epidermidis from the commensals. METHODS Fifty five S. epidermidis isolates from various device related infections such as endophthalmitis following intra-ocular lens (IOL) implantation, intravascular (IV) catheter related sepsis and orthopaedic implant infections, were studied for slime production, biotyping, antibiotic sensitivity; and mec A and ica positivity by the recommended procedures. RESULTS Twenty three (41.8%) isolates were multi-drug resistant, 26 (65.2%) were slime producers, 30 (54.5%) were adherent, 23 (41.8%) possessed the intercellular adhesin (ica) gene, and 28 (50.9%) harboured the mec A gene. Biotypes I and III were the commonest, most members of which were multi- drug resistant. Twenty two (73.3%) of the 30 adherent bacteria were slime producers as opposed to only 4 (16%) of the 25 non-adherent bacteria (P<0.001). A vast majority i.e. 21 (91.3%) of the 23 ica positive organisms were adherent to artificial surfaces in contrast to only 9 (28.1%) of the 32 non-ica positive organisms (P<0.001). Twenty (86.9%) of the 23 ica positive bacteria were slime producers, as opposed to only 6 (18.7%) of the 32 ica negative bacteria (P<0.001). Of the 23 multi-drug resistant isolates, 19 (82.6%) carried the mec A gene. INTERPRETATION & CONCLUSIONS The present findings showed that ica AB and mec A were the two important virulence markers of S. epidermidis in implant infections and slime was responsible for the sessile mode of attachment on the devices.
