Abstract
Acquired lens colobomas secondary to ocular surgeries are scarcely described in the literature. We describe two cases of acquired lens coloboma in two infants with glaucoma who underwent ocular surgery. The coloboma in the first case was likely because of direct trauma to the lens zonules during an optical iridectomy with a vitrectomy cutter, resulting in localized loss of zonules and consequently localized lens coloboma. The coloboma in the second case was noticed during examination under anesthesia after scleral buckling and cryopexy for retinal detachment. The cause for coloboma development in this case could be disruption of the lens zonules because of stretching of the globe after scleral buckle surgery or because of injury to zonules during scleral buckling and the cryopexy procedure.

Abstract
The Government of India has worked to expand access to injectable contraceptives through the introduction of a three-monthly injectable contraceptive MPA under the ‘Antara’ program in 2017. However, the uptake of injectable contraceptives has remained low, and few studies have investigated the experiences of public health facility injectable clients in India. We examined factors associated with continuing, discontinuing, and switching methods among injectable users obtaining services from public health facilities in the Indian states of Karnataka and Maharashtra. The study team recruited respondents (N=1009) that had received their first injectable dose from in public sector facilities between February – May 2019 and conducted a follow-up visit at their residence in December 2020. We used multivariate logistic regression to study the association of the demographic characteristics, service quality, satisfaction with services, follow-up visits, and decision-making on injectable continuation and switching to other family planning methods. Injectable usage rates declined significantly, with 44% of clients receiving a second dose and only 16% receiving a third dose. Over half of women (54%) cited problems related to periods as the reason for discontinuing injectable use after the first dose. Respondents were more likely to continue their method at third dose if they were older (25-35 years) (OR:1.68, p<0.05) and had received a reminder for a follow-up dose (OR: 2.41, p Our results also highlight the importance of addressing side-effects experience by women, which may be better managed by community-based follow-up visits and high-quality counselling services.

Abstract
A 54-year-old-man underwent trabeculectomy with mitomycin-C (0.02%). At 4-week follow-up, there was an elevated, well-circumscribed bleb with raised intra-ocular pressure (IOP) of 32-mmHg, with a classic “ring of steel” appearance, typically seen in a tenon's cyst. A sub-tenon needle revision re-established aqueous flow. Two weeks later, the IOP was 8-mmHg without any anti-glaucoma medications. A diffuse well formed bleb was noted. Careful ocular examination helps to identify early post-operative localized bleb that may appear like a “ring of steel” but can be managed by needling, unlike a tenon's cyst, which would require more extensive intervention.

Abstract
The Government of India has promoted the expansion of access to and uptake of intrauterine devices (IUDs), during both the interval (IIUD) and postpartum (PPIUD) periods, as part of its Family Planning 2020 initiative. This study, conducted by EngenderHealth as part of the Expanding Access to IUD Services in India project, examines IIUD and PPIUD continuation rates over time and investigates factors associated with IUD continuation. We recruited respondents (N = 5024) through a repeated cross-sectional household study between February and December 2019. We identified respondents using IUD client data from public health facility registers in 20 districts of Gujarat and Rajasthan. We compared continuation rates for IIUD and PPIUD adopters and used regression analyses to measure the association between continuation and demographic, quality of care, and counselling variables. IIUD continuation rates decreased from 85.6% to 78.3% and PPIUD rates decreased from 78.5% to 70.7% between month 3 and month 12. Clients experiencing side effects or other problems were 15 times more likely to discontinue IUD use than clients who did not. Clients who received IUD counselling prior to insertion were more likely to continue than those who did not. IUD continuation increased significantly in cases where both partners jointly selected the method compared to situations where women decided alone. Several sociodemographic factors were associated with continuation. Our study demonstrates the value and benefits of programmes offering IUD services emphasising quality counselling and client-centred care to increase access, uptake, and continuation.

Abstract
The activation of mostly quiescent haematopoietic stem cells (HSCs) is a prerequisite for life-long production of blood cells1. This process requires major molecular adaptations to allow HSCs to meet the regulatory and metabolic requirements for cell division2-4. The mechanisms that govern cellular reprograming upon stem-cell activation, and the subsequent return of stem cells to quiescence, have not been fully characterized. Here we show that chaperone-mediated autophagy (CMA)5, a selective form of lysosomal protein degradation, is involved in sustaining HSC function in adult mice. CMA is required for protein quality control in stem cells and for the upregulation of fatty acid metabolism upon HSC activation. We find that CMA activity in HSCs decreases with age and show that genetic or pharmacological activation of CMA can restore the functionality of old mouse and human HSCs. Together, our findings provide mechanistic insights into a role for CMA in sustaining quality control, appropriate energetics and overall long-term HSC function. Our work suggests that CMA may be a promising therapeutic target for enhancing HSC function in conditions such as ageing or stem-cell transplantation.

Abstract
BACKGROUND Recent reports from this lab have demonstrated a higher incidence of NETs, nitrosative, as well as oxidative stress, and have a direct correlation with the severity of sepsis and organ damage. However, the mechanistic perspective of NETs induced organ damage has not been understood at the cellular and molecular level. Interaction of inducible nitric oxide synthase (iNOS) with Rac2 in regulating reactive oxygen species (ROS) and reactive nitrogen species (RNS) generation and its implications in microbial killing has been reported. This study was, therefore, undertaken in neutrophils of sepsis patients to investigate the functional importance of iNOS-Rac2 interaction in ROS/ RNS, peroxynitrite generation, NETs generation, and NETs mediated cell death. METHODS The study was conducted on 100 patients with sepsis and 50 healthy volunteers. Interaction between iNOS and Rac2 was performed using co-immunoprecipitation and co-immunolabeling assay. Free radicals involving ROS and RNS were evaluated using cytochrome c reduction assay. NETs formation was evaluated by fluorescence microscopy. The cytotoxic effect of NETs was assessed on lung carcinoma cell line (A549) using colorimetric Alamar blue assay. RESULTS Enhanced interaction between iNOS and Rac2 was found in sepsis neutrophils in comparison with control. This was accompanied by an increased level of superoxide (O2.-), nitric oxide (NO), and peroxynitrite (ONOO-) which were decreased in the presence of NAC, DPI, and 1400 W, signifying the role of iNOS-Rac2 interaction. Enhanced NETs release from activated sepsis neutrophils were abrogated in the presence of DPI. NETs from sepsis neutrophils exert a cytotoxic effect on lung epithelial cells (A549) in a concentration-dependent manner. CONCLUSION Our findings exhibit the functional role of iNOS-Rac2 interaction in ROS/RNS, peroxynitrite generation, NETs generation, and NETs mediated cell death.

Abstract
Weyl semimetals host chiral fermions with distinct chiralities and spin textures. Optical excitations involving those chiral fermions can induce exotic carrier responses, and in turn lead to novel optical phenomena. Here, we discover strong coherent terahertz emission from Weyl semimetal TaAs, which is demonstrated as a unique broadband source of the chiral terahertz wave. The polarization control of the THz emission is achieved by tuning photoexcitation of ultrafast photocurrents via the photogalvanic effect. In the near-infrared regime, the photon-energy dependent nonthermal current due to the predominant circular photogalvanic effect can be attributed to the radical change of the band velocities when the chiral Weyl fermions are excited during selective optical transitions between the tilted anisotropic Weyl cones and the massive bulk bands. Our findings provide a design concept for creating chiral photon sources using quantum materials and open up new opportunities for developing ultrafast opto-electronics using Weyl physics.

Abstract
BACKGROUND This study aims to investigate radiation beam geometry of Cyberknife beam and change in dosimetric characteristics of six megavoltage (6MV) flattening filter free (FFF) beam after passing through high density cadmium free compensator alloy. MATERIAL AND METHODS In this experimental study, changes in FFF beam dosimetric characteristics after passing through compensator alloy was measured. Transmitted intensity of FFF beam was measured in air by an ion chamber at a source to detector distance (SDD) of 800mm. Extended SDD measurement also has been performed at a distance of 1270mm to analyze scattering due to compensator. Linear attenuation coefficient (µeff) was measured for cadmium free compensator alloy using simple exponential attenuation model. Percentage depth doses (PDDs) have been measured by a radiation field analyzer with compensator material to observe the beam hardening and change in surface doses and depth doses. RESULTS Linear attenuation coefficient of compensator alloy was measured 0.042 (Standard Deviation ±0.00099) mm-1 and it was found that there is no change with increase in collimator size. Even after increasing distance source from detector, µeff has no change. PDDs were found to increase with thickness of compensator. PDD from a 60mm collimator size increased by 5% and 6% at a depth of 100mm and 200mm, respectively in water. PDD also increased with collimator size less significantly. Surface dose was found to decrease with increase in compensator thickness. CONCLUSION Cyberknife beam has been found to be narrow beam geometry. FFF beam contains lesser scattered photons. Presence of high density compensator filters out the soft x-ray photon causes significant dosimetric changes.

Abstract
Wolbachia, a maternally inherited bacterium induces reproductive alterations in its hosts such as feminization of males, male killing and parthenogenesis. It is the most diverse endosymbiont infecting more than 70% of the insects ranging from pests to pollinators. Kerria lacca-a hemipteran is a sedentary, oriental insect known to produce lac-the only resin of animal origin. The present study was conducted to screen the presence of Wolbachia and its associated phages in the two infrasubspecific forms (four insect lines) of K. lacca viz. kusmi and rengeeni differing from each other on the basis of host preference. Wolbachia and its associated phage were found to be prevalent in all the insect lines analyzed. We, hereby, report the presence of WO-phage (Wolbachia phage) for the first time in K. lacca. Further, phylogenetic data differentiated the kusmi and rengeeni infrasubspecific forms into two different groups on the basis of WO-phage sequences.

Abstract
Corticosteroids form the mainstay of therapy for all forms of nephrotic syndrome. The long-term use of this medication is associated with serious side effects including adrenocortical suppression. The primary objective of this study was to identify adrenocortical suppression (assessed by single morning serum cortisol levels) in children with nephrotic syndrome on treatment with low-dose alternate day steroids. This cross-sectional study was conducted in the Department of Pediatrics in a tertiary care hospital from January 2014 to January 2015. Seventy children (1–18 years) with nephrotic syndrome (steroid sensitive and resistant) who were in remission and on low-dose alternate day steroids for at least 8 weeks or had received steroids of 2 mg/kg/d for at least 2 weeks in the last 1 year (infrequent relapsers) were enrolled. Relevant history was taken, clinical examination was done and blood samples were drawn for serum cortisol, lipid profile, kidney function tests, fasting blood sugar, glycated hemoglobin (HbA1c), and serum albumin. Forty percent (28/70) children had adrenocortical suppression as assessed by low morning serum cortisol levels. The mean serum cortisol levels were 188 nmol/L and were significantly lower in frequently relapsing individuals (85.9 nmol/L) as compared to other types of nephrotic syndrome (P = 0.05). The prevalence of adrenocortical suppression was higher in steroid-resistant patients (57%) as compared to 28% in frequently relapsing and 11% in steroid-dependent patients. Fifty-seven percent of patients with adrenocortical suppression had short stature while 50% had obesity. All individuals had normal serum HbA1c levels. The cumulative steroid doses and total duration of corticosteroid therapy were significantly higher in patients with adrenocortical suppression. Children with nephrotic syndrome treated with low-dose alternate day steroids have a high prevalence of adrenocortical suppression on screening with single morning cortisol sample. Those with frequently relapsing or steroid-resistant diseases are at a higher risk of suppression.

Abstract
Sepsis is a condition caused by infection followed by unregulated inflammatory response which may lead to the organ dysfunction. During such condition, over-production of oxidants is one of the factors which contribute cellular toxicity and ultimately organ failure and mortality. Antioxidants having free radicals scavenging activity exert protective role in various diseases. This study has been designed to evaluate the levels of oxidative and antioxidative activity in sepsis patients and their correlation with the severity of the sepsis. A total of 100 sepsis patients and 50 healthy controls subjects were enrolled in this study from the period October 2016 to June 2017. The investigation included measurements of oxidative enzyme, myeloperoxidase (MPO), antioxidant enzymes including superoxide dismutase activity (SOD) and catalase activity (CAT) and cytokines (TNF-α, IL-8 and IFN-γ). Furthermore, the level of these activities was correlated with severity of sepsis. Augmented levels of oxidants were found in sepsis as demonstrated by DMPO nitrone adduct formation and plasma MPO level activity (1.37 ± 0.51 in sepsis vs 0.405 ± 0.16 in control subjects). Cytokines were also found to be increased in sepsis patients. However, plasma SOD and CAT activities were significantly attenuated (P < .001) in the sepsis patients compared with controls subjects. Moreover, inverse relation between antioxidant enzymes (SOD and CAT) and organ failure assessment (SOFA), physiological score (APACHE II), organ toxicity specific markers have been observed as demonstrated by Pearson's correlation coefficient. This study suggests that imbalance between oxidant and antioxidant plays key role in the severity of sepsis.

Abstract
We demonstrate a novel hyperspectral imaging spectrometer based on computational imaging that enables sensitive measurements from smaller, noisier, and less-expensive components (e.g. uncooled microbolometers), making it useful for applications such as small space and air platforms with strict size, weight, and power requirements. The computational reconfigurable imaging spectrometer (CRISP) system exploits platform motion and a spectrally coded focal-plane mask to temporally modulate the optical spectrum, enabling simultaneous measurement of multiple spectral bins. Demodulation of this coded pattern returns an optical spectrum in each pixel.

Abstract
The aim of this study was to assess the effects of low levels of dietary fish meal (FM) and fish oil (FO) on disease resistance and gut associated lymphoid tissue (GALT) response after an experimental intestinal infection with V. anguillarum in European sea bass (Dicentrarchus labrax) For that purpose, sea bass juveniles were fed one of four diets containing combined levels of FO and FM as follows: 20%FM/6%FO, 20%FM/3%FO, 5%FM/6%FO and 5%FM/3%FO during 153 days. At the end of the feeding trial, fish were subjected to either an in vivo exposure to a sub-lethal dose of V. anguillarum via anal inoculation or to an ex vivo exposure to V. anguillarum. Additionally, inducible nitric oxide synthase (iNOS) and tumor necrosis factor α (TNFα) gut patterns of immunopositivity were studied. Growth performance was affected by dietary FM level, however ex vivo gut bacterial translocation rates and survival after the in vivo challenge test were affected by dietary FO level. After 5 months of feeding, low dietary FM levels led to a posterior gut up-regulation of interleukin-1β (IL-1β) and TNFα, major histocompatibility complex-II (MHCII) and cyclooxygenase-2 (COX2), which in turn reduced the gut associated lymphoid tissue (GALT) capacity of response after 24 h post infection and conditioned European sea bass capacity to recover gut homeostasis 7 days post infection. Immunoreactivity to anti-iNOS and anti-TNFα presented a gradient of increased immunopositivity towards the anus, regardless of the dietary FM/FO fed. Strong positive anti-TNFα isolated enterocytes were observed in the anterior gut in relation to low levels of dietary FM/FO. Submucosa and lamina propria immunoreactivity grade was related to the amount of leucocyte populations infiltrated and goblet cells presented immunopositivity to anti-iNOS but not to anti-TNFα. Thus, reducing FO content from 6% to a 3% by VO in European sea bass diets increases ex vivo and in vivo gut bacterial translocation rates, whereas reducing FM content from 20% down to 5% up-regulates the expression of several posterior gut inflammation-related genes conditioning fish growth and GALT capacity of response after bacterial infection.

Abstract
PURPOSE Influenza epidemics and periodic pandemics occur worldwide resulting in significant mortality, morbidity and economic loss. There is need for a sensitive, rapid and cost-effective assay to detect, type and sub-type influenza viruses, as cell culture has a long turnaround time. MATERIALS AND METHODS Nasopharyngeal swabs were collected from patients presenting with influenza-like illness (ILI) at AIIMS OPD and Primary Health Centre Ballabhgarh (Haryana). From June 2007 to January 2009 and then from September to November 2009, of 1567 specimens collected, 544 were randomly selected and were tested by virus culture using Madin-Darby Canine Kidney (MDCK) cells and by reverse transcription polymerase chain reaction (RT-PCR) for influenza A using primers for matrix gene and for influenza B using non-structural gene (NS) primers. All influenza A positives were sub-typed using primers for HA and NA genes of A/H1, A/H3. A separate multiplex RT-PCR having primers from matrix and HA genes of pandemic A (H1N1) pdm09 viruses was carried out on samples collected after September 2009. RESULTS Of the 544 samples, 136 (25%) were positive for influenza by RT-PCR. Further typing analysis revealed 86 (63.2%) were typed as influenza A and 47 (34.5%) as influenza B viruses and 3 (2%) samples showed dual infection with influenza A and B. Of the 86 influenza A positive samples 48 (55.8%) were identified as seasonal influenza A/H1N1, 22 (25.6%) as A (H1N1) pdm09 and 16 (18.6%) as A/H3N2. Comparison of influenza positivity using virus culture revealed that only 97/136 (71.3%) were influenza positive. Sensitivity of viral detection was lowest for seasonal A/H1 (26/48; 54%), followed by H3N2 (11/16; 68.7%) and influenza B (38/47; 80.8%); all influenza A/H1N1pdm09 viruses were detected by both methods. CONCLUSION RT-PCR is a sensitive, low cost and rapid screening test for diagnosing influenza infection during epidemics and pandemics. mRT-PCR increased the detection rates for influenza by 28.6% as compared with virus isolation and thus is a useful assay in both diagnostic and epidemiological settings in resource poor countries.

Abstract
The ocular system can be affected in systemic lupus erythematosus (SLE) in one third of patients. However, optic nerve involvement is relatively uncommon, but is more so in pediatric SLE patients, where it can occur in 1% of cases. We report three children with SLE who presented with optic nerve involvement. Two children had optic neuritis, with optic neuritis being the first manifestation in one child. The third child had ischaemic optic neuropathy secondary to antiphospholipid syndrome. A careful work up for SLE should be performed in every child with optic nerve disease. Prompt diagnosis and early treatment results in a better prognosis.

Abstract
Colostrum, the mammary secretion during first 2-4 days of lactation, provides all the essential components of nutrition and passive immunity required by the newborn. Pregnancy induced hypertension (PIH), glucose intolerance and anaemia are common medical complications observed during pregnancy in Indian women and their effects were studied on the composition of colostrum collected within 24 hours of delivery from lactating women included in the study. PIH during pregnancy significantly decreased colostrum IgA and total proteins, but showed a significant increase in K(+) levels, where as women with glucose intolerance showed a significant decrease in total lipids and lactose and an increase in Na(+) levels in colostrum compared to normal controls. The group with anaemia also showed a significant decrease in colostrum IgA and total protein levels when compared with the control group. Awareness about the changes that occur in the composition of colostrum during complicated pregnancies can be an important and useful tool for preventive and protective paediatrics.

Abstract
Aquaculture of carnivorous species has strongly relied on fish meal and fish oil for feed formulation; however, greater replacement by terrestrial plant-based products is occurring now. This rapid change in dietary environment has been a major revolution and has to be taken into consideration in breeding programs. The present study analyzes potential consequences of this nutritional tendency for selective breeding by estimating genetic parameters of BW and growth rates estimated by the thermal growth coefficient (TGC) over different periods with extremely different diets. European sea bass (Dicentrarchus labrax L.) from a factorial cross (1,526 fish) between 25 sires and 9 dams were used to estimate heritabilities and genotype by diet interaction. Starting 87 d after fertilization (2.5 g), one-half of the sea bass were fed a diet containing marine products (M), and the other one-half were fed a totally plant-based (PB) diet (without any fish meal or fish oil). The fish were individually tagged, reared in a recirculated system, and genotyped at 13 microsatellites to rebuild parentage of individuals. Body weight and TGC were measured for 335 d until fish fed the M diet reached 108.3 g of BW. These traits were significantly less in fish fed the PB diet (P<0.05) in the very first stages after the dietary shift, but the difference in TGC between diets rapidly disappeared (P>0.1). Survival was significantly less in fish fed the PB diet (PB=64.7%, M=93.7% after 418 d, P<0.05). This work identified moderate heritabilities (0.18 to 0.46) for BW with both diets and high genetic correlations between diets (0.78 to 0.93), meaning low genotype by diet interactions, although diets were extremely different. Heritabilities of TGC (0.11 to 0.3) were less than for BW as well as genetic correlations between diets (0.43 to 0.64). Using such extremely different diets, predicted BW gains in different scenarios indicated that selecting fish for growth on a marine diet should be the most efficient way to increase growth on plant-based diets, meaning that, in this case, indirect selection should be more efficient than direct selection.
