Abstract
The rise of Crimean-Congo Hemorrhagic Fever (CCHF), poses a significant global health challenge, urging immediate action and continuous surveillance. With no available vaccines, monitoring pathogen presence is critical to identify at-risk areas promptly. A study was designed to assess the incidence of CCHF virus in goats and cattle using commercial ELISA IgG kits in tribal-dominated regions. Overall, 16% of the samples (n = 63/393) were positive for CCHF virus-specific IgG antibodies, whereas sero-prevalence detected in cattle 11.6% [95% CI:7-17.7] and in goats 18.9% [95% CI: 13.76-24.01], respectively. Statistically, Animal gender and age didn't significantly affect prevalence (p-value >0.05). Our finding indicates unnoticed CCHF virus circulation. Notably, lack of public awareness about zoonotic diseases in the study region was recorded. To combat this emerging tick-borne disease effectively, it's crucial to screen individuals with hemorrhagic manifestations in healthcare settings and active surveillance of ticks to prevent unwarranted public health outbreaks and design preventive interventions.

Abstract
The present study comprehensively evaluates the postnatal growth, hematology, telomere length, and semen attributes of multiple clones and re-clone derived from superior buffalo breeding bulls. To the best of our knowledge, we successfully produced multiple clones and a re-clone of an earlier cloned buffalo bull from an embryo developed from an adult bull's skin-derived cell for the first time. The cloned bulls' growth, blood hematology, plasma biochemistry, and telomere length were all shown to be normal at various stages of development. The bulls were used for semen production after being screened for testicular growth and training. Semen characteristics such as volume, concentration, and initial motility of fresh sperm as well as motility and kinetics characteristics such as straightness (STR), average lateral head displacement (ALH), and beat cross frequency (BCF) of frozen-thawed sperms of the cloned bulls were found to be similar to those of non-cloned bulls, including the donor bulls. Additionally, it was found that cloned bulls' functional sperm attributes, including acrosome intactness, mitochondrial membrane potential, and superoxide anion status, were comparable to those of non-cloned bulls. These characteristics are necessary for sperm to pass through the female reproductive system, penetrate the oocyte, and efficiently fertilize. Finally, this study adds to our understanding of the postnatal development, hematology, telomere length, and sperm characteristics of superior buffalo breeding bulls that have been cloned and re-cloned. The findings provide the groundwork for improving cloning practices, refining reproductive procedures, and optimizing the use of cloned genetic material in animal breeding and conservation.

Abstract
BACKGROUND OBJECTIVES The tribal populations are vulnerable to mental health issues owing to various reasons. However, limited research has been conducted to assess depression and related determinants among tribal adults aged ≥45 yr (45 years and older). The present study aimed to assess the prevalence and sociodemographic and health determinants of depressive symptoms among the scheduled tribe (ST) population aged ≥45 yr in India. METHODS The present study analyzed the Wave I data of the Longitudinal Ageing Study in India conducted between April 2017 to December 2018. The outcome variables in the present study were self-reported depressive symptoms. Two internationally recognised tools, the Centre for Epidemiologic Studies Depression scale (CES-D) and Composite International Diagnostic Interview-Short Form (CIDI-SF), were used to obtain the data, however, only the CES-D data are utilized in this study. The present study focused on 12,215 ST individuals aged ≥45 yr from whom information about depressive symptoms was collected and analyzed. RESULTS Nearly 25 per cent ST population aged 45 yr or older experienced depressive symptoms. The likelihood of experiencing depressive symptoms among the ST population aged ≥45 yr was negatively associated with 10 or more years of education and living with children and others and positively associated with experiencing multiple morbidity conditions. INTERPRETATION CONCLUSIONS Given the substantial burden of depression among the adult ST population, the present study lays emphasis on raising the awareness about depressive symptoms and strengthen the availability of mental health services among the ST community through intensive campaigns and engagement of ST individuals along with other key stakeholders. Higher education, living with spouse and children and a physically active lifestyle can play a crucial role in limiting depressive symptoms among the tribal adults (≥45 yr). It is paramount to regularly screen depressive symptoms and conduct more microlevel studies to evaluate socioeconomic and health determinants of depressive symptoms among ST communities living in different geographic regions.

Abstract
Mito-Q is a well-known mitochondria-specific superoxide scavenger. To our knowledge, the effect of Mito-Q on buffalo oocyte maturation and developmental competency of cloned embryos has not been examined. To investigate the effects of Mito-Q on the in vitro maturation (IVM) of buffalo oocytes and the developmental competence of cloned embryos, different concentration of Mito-Q were supplemented with IVM (0, 0.1, 0.5, 1, 2 μM) and in vitro culture (IVC) medium (0, 0.1 μM). Supplementation of IVM medium with 0.1 μM Mito-Q significantly (P ≤ 0.05) increased the cumulus expansion, nuclear maturation, mitochondrial membrane potential (MMP) and antioxidants genes (GPX1 and SOD2) expression and effectively reduced ROS production leading to a significant improvement in the maturation rate of buffalo oocytes. Further, the supplementation of 0.1 μM Mito-Q in IVC medium promotes the cleavage and blastocyst rate significantly over the control. Mito-Q supplementation improves (P ≤ 0.05) MMP, antioxidant gene (GPX1) expression and reduced the ROS level and apoptosis related genes (caspase 9) expression in cloned blastocysts. In conclusion, the present study demonstrated that the supplementation of 0.1 μM Mito-Q in IVM and IVC media exerts a protective role against oxidative stress by reducing ROS production and improving MMP, fostering improved maturation of buffalo oocytes and enhanced developmental competence of cloned embryos. These findings contribute valuable insights into the optimization of assisted reproductive technologies protocols for buffalo breeding and potentially offer novel strategies to enhance reproductive outcomes in livestock species.

Abstract
The current research was undertaken to scrutinize the effect of leaf meal mixture as concentrate mixture in the ration of goats. Leaf meal mixture (LMM) was prepared using equal quantities of ten top-foliages namely Acacia nilotica, Celtis australis, Ficus palmata, Ficus religiosa, Grewia optiva, Melia azadarach, Morus alba, Quercus incana, Salix alba and Zizyphus jujube obtained from district Poonch of Jammu region in western Himalayas. The LMM prepared was substituted for 15% in the concentrate mixture being fed to the goats. The study constituted of two trials. Concentrate mixture offered to the animals was in mash and multi-nutrient block in first and second trial respectively. A total of twelve non-descript, adult male goats were selected for each trial. Goats of 0-14 months age (27.71 ± 2.96 kg live body weight) of for first trial while goats of 12-16 months age (27.02 ± 2.93 kg live weight) for second trial were divided into control and treatment groups as per randomized block design and fed ad-lib wheat straw and concentrate mixture @ (20 g/kgW0.75). No significant variation was observed (p > 0.05) in body weight, feed and DM intake among all groups in both trials. Comparable intake as well as digestibility of various nutrients like DM, OM, CP, EE, CF, NFE, NDF, ADF and TDN were found between the two groups during individual trials. There was a positive nitrogen, calcium and phosphorus balance among all experimental animals in both the trials. Serum enzymes ALT, AST and haemato-biochemical parameters like total protein, albumin, globulin, albumin: globulin and blood urea nitrogen (BUN) showed no significant differences during both trials in all groups, being within normal physiological levels. However, haemoglobin concentration was significantly higher (P < 0.05) in treatment group with respect to the control group in first trial. On the basis of current results, it can be established that leaf meal mixture can successfully be used to replace concentrate mixture up to 15% in the ration of goats without expecting any adverse impacts on their growth and overall health.

Abstract
Occurrence of fluoride in groundwater is a serious concern due to its fatal effects. Functionalized hexagonal boron nitride sheets have been combined with nickel hydroxide nanoparticles by a one step process and a hybrid adsorbent Ni(OH)2@hBN has been developed with an exceptionally high fluoride adsorption capacity of 365 mg g-1, higher than those of Ni(OH)2 and hBN. This maximum adsorption capacity is higher than those of most common adsorbents used for defluoridation including activated alumina, reported nickel oxide and carbon-based 2D material-supported alumina adsorbents. The presence of functionalized boron nitride significantly increased the surface area to 680 m2 g-1 with a pore volume of 0.33687 cm3 g-1 and provided rich hydroxyl group-containing surface sites for the removal of fluoride present in contaminated water. In addition, the adsorption of fluoride onto boron nitride-modified nickel hydroxide followed pseudo-second-order kinetics and the equilibrium data fitted well with the Langmuir adsorption isotherm, suggesting a monolayer adsorption mechanism. Furthermore, the material developed is tested with the water sample collected from a real affected area, from the Dhar district of India, and the material showed promising results in terms of fluoride removal efficacy.

Abstract
This study was attempted to estimate the genetic parameters of semen quality traits in buffalo bulls. The study data consisted of 10975 ejaculates from 45 Murrah buffalo bulls (aged 24-72 months) used for breeding program during year 2010 to 2020. Semen quality traits (ejaculate volume, concentration of sperm, mass activity, initial and post-thaw motility, number of sperms per ejaculate, motile sperm number and discard rates) were studied. It was observed that average ejaculate volume was 2.82 ± 1.45 mL with mean concentration of 1040.12 ± 523.26 million/mL. Higher heritability was observed for number of sperms per ejaculate, number of motile sperm and sperm concentration. Significant phenotypic correlation was obtained between volume and number of sperms per ejaculate as well as volume and number of motile sperms. Likewise, significant phenotypic correlation was evident between sperm concentration with sperm number per ejaculate. Highest phenotypic correlation was obtained between sperm count per ejaculate and motile sperm count. Estimated genetic trends showed significant change in volume and motile sperm number. In conclusion, this study ascertains that genetic parameters of semen traits can be considered during the selection of buffalo bulls in breeding program.

Abstract
Various literature studies (Table 6) have reported that dispersion of metal nanoparticles (NPs) on graphitic carbon nitride g-C3N4 (M/CN) has considerably improved the photocatalytic hydrogen yield. It is understood that metal NPs create active sites on the surface of CN and act as a cocatalyst. However, the precise changes induced by different metal NPs on the surface of CN still elude us. Here, we report a thorough understanding and comparison of the morphology, metal-support interactions, interfacial charge transfer kinetics, and band characteristics in different M/CN (M = Pt, Pd, Au, Ag, Cu) correlated with photocatalytic activity. Among all metals, Pt/CN was found to be the best performer both under sunlight and UV-visible irradiation. Under sunlight, maximum H2@ 2.7 mmol/h/g was observed over Pt/CN followed by Pd/CN > Au/CN > Ag/CN > Cu/CN ≈ CN. The present study revealed that among all metals, Pt formed superior interfacial contact with g-C3N4 as compared to other metals. The maximum Schottky barrier height (Φb,Pt) of 0.66 V was observed at Pt/CN followed by Φb,Au/CN (0.46 V) and Φb,Pd/CN (0.05 V). The presence of electron-deficient Pt in Pt-XPS, decrease in the intensity of d-DOS of Pt near the Fermi level in VB-XPS, increase in CB tail states, and cathodic shift in Vfb in MS plots sufficiently confirmed strong metal-support interactions in Pt/CN. Due to the SPR effect, Au and Ag NPs suffered from agglomeration and poor dispersion during photodeposition. Finely dispersed Pt NPs (2-4 nm, 53% dispersion) successfully competed with shallow/deep trap states and drove the photogenerated electrons to active metallic sites in a drastically reduced time period as investigated by femtosecond transient absorption spectroscopy. Typically, an interfacial electron transfer rate, KIET,avg, of 2.5 × 1010 s-1 was observed for Pt/CN, while 0.087 × 1010 s-1 was observed in Au/CN. Band alignment/potentials at M/CN Schottky junctions were derived and most favorable in Pt/CN with CB tail states much above the water reduction potential; however, in the case of Pd, these extend much below the H+/H2 potential and hence behave like deep trap states. Thus, in Pd/CN (τ0 = 4200 ps, 49%) and Ag/CN (3870 ps, 53%), electron deep trapping dominates over charge transfer to active sites. The present study will help in designing futuristic new cocatalyst-photocatalyst systems.

Abstract
The present study was conducted to observe the effects of removal of seminal plasma of Pantja buck semen and supplementation of bovine seminal plasma (BSP) in the extender before cryopreservation. In a preliminary experiment, different levels of BSP were supplemented (1, 3, 5, 7, and 9% v/v) in egg yolk (7.5% egg yolk)-tris (EYT) extender and used for cryopreservation of Pantja buck semen. Results in terms of motility, viability, plasma membrane integrity, acrosome integrity, and lipid peroxidation showed that 5% BSP was suitable for maintaining Pantja buck semen quality during cryopreservation. In the final experiment, pooled semen from four Pantja bucks was split into three aliquots (I, II, and III). Aliquot I was directly diluted in EYT extender and grouped as the control (C); aliquot II and III were washed separately with TALP solution and diluted as D1 (Washed semen with EYT extender) and D2 (Washed semen with EYT extender containing 5% BSP), respectively. Seminal attributes (sperm individual motility, viability, plasma membrane integrity, acrosome integrity, and total morphological abnormalities) were assessed at the postdilution, postequilibration, and post-thawing stages. Alanine aminotransferase (ALT), aspartate aminotransferase (AST), malondialdehyde (MDA) concentration, and glutathione peroxidase (GSH-Px) activity were measured at post-thaw. Washed semen significantly improved (p < 0.05) seminal parameters at post-thaw compared with unwashed semen (control). A significant difference (p < 0.05) was observed in seminal attributes between freezing stages and between dilution groups. Significantly higher (p < 0.05) post-thaw sperm motility, viability, plasma membrane integrity, acrosome integrity, and GSH-Px activity, and significantly lower (p < 0.05) MDA concentration and extracellular release of enzymes (ALT, AST) were observed in group D2 compared with control and D1. The results of the present study demonstrated that cryopreservation of washed Pantja buck semen diluted with 5% BSP-supplemented EYT extender can improve post-thaw semen quality.

Abstract
Hierarchical micro/nanostructures are constructed by micro-scaled objects with nanoarchitectures belonging to an interesting class of crystalline materials that has significant applications in diverse fields. Featured with a large surface-to-volume ratio, facile mass transportation, high stability against aggregation, structurally enhanced adsorption, and catalytical performances, three dimenisional (3D) hierarchical metal oxides have been considered as versatile functional materials for waste-water treatment. Due to the ineffectiveness of traditional water purification protocols for reclamation of water, lately, the use of hierarchical metal oxides has emerged as an appealing platform for the remediation of water pollution owing to their fascinating and tailorable physiochemical properties. The present review highlights various approaches to the tunable synthesis of hierarchical structures along with their surface modification strategies to enhance their efficiencies for the removal of different noxious substances. Besides, their applications for the eradication of organic and inorganic contaminants have been discussed comprehensively with their plausible mechanistic pathways. Finally, overlooked aspects in this field as well as the major roadblocks to the implementation of these metal oxide architectures for large-scale treatment of wastewater are provided here. Moreover, the potential ways to tackle these issues are also presented which may be useful for the transformation of current water treatment technologies.

Abstract
To date, remarkable progress has been achieved in the development of photocatalysts owing to their high activity, selectivity, and tunable light absorption in the visible light range. Recently, heterogeneous photocatalytic systems have emerged as potential candidates due to their beneficial attributes (e.g., high surface area, ease of functionalization and facile separation). Herein, we provide a concise overview of the rational design of heterogeneous photocatalysts by grafting photoactive complexes on heterogeneous support matrices via covalent grafting and their detailed characterization techniques, which have been followed by the landmark examples of their applications. Also, major challenges and opportunities in the forthcoming progress of these appealing areas are emphasised.

Abstract
Introduction: Foramen ovale is one of the most significant foramina of skull base and transmits mandibular nerve. Its detailed knowledge is crucial in treatment of trigeminal neuralgia and various diagnostic practices. Aim: Aim of the study was to provide anatomical data of foramen ovale regarding number, shape, diameters and its relation to nearby bony landmarks. Material and method: The present study was ethically approved and 100 dry adult human skulls were included in the study to evaluate 200 foramina ovale. Non-metric parameters were observed and metric parameters were measured with Vernier calliper and goniometer. Results:Different kinds of shapes were found in foramen ovale. Variant features in the form of bony spine, ridge, foramen or bar were identified. The means of anteroposterior and transverse diameter of foramen ovale were found to be 8.16 and 4.97 mm on the right side, and 7.68 and 4.74 mm on the left side. The mean distance of its anterior and posterior ends from the midsagittal plane were 22.69 and 28.92 mm on the right side, and 22.18 and 22.66 mm on the left side. Distance from the lateral border of foramen ovale to the posterior end of zygoma and midpoint of infratemporal crest was found to be 30.65 and 21.05 mm on the right, and 30.30 and 20.87 mm on the left side. The mean of angle of foramen ovale with midsagittal was 45.44º on the right side and 45.78º on the left side. Conclusion:Variations found in foramen ovale are key points to keep in mind while operating in this region. Measured metric parameters were found to a higher extent on the right side than the left one. The present study will be helpful for both further research and neurosurgeons operating in this region.

Abstract
UNLABELLED Male reproductive functions are governed by hypothalamic pituitary testicular axis. If any component of this axis malfunctions, then hypogonadism will develop which is characterized by ill-defined secondary sexual features and low serum testosterone. The common patterns seen are primary and secondary testicular failure in the young; and late onset hypogonadism in the elderly. All such cases can be virilized and managed by androgen supplementation. Spermatogenesis can be induced by use of appropriate gonadotropins in selected cases. The aim of the study was to find out the pattern, management and outcome of male hypogonadism. MATERIAL It was a prospective questionnaire based observational study, carried out on infertile hypogonadic males, attending medicine outdoor at medical college hospital from January 2015 to December 2020. There were 50 males with hypogonadic features, cases of late onset of hypogonadism were excluded. Sexual maturity rating, semen analysis, serum testosterone and FSH level were estimated in all patients at baseline and at 6 months duration of treatment. Testicular biopsy, Karyotyping and MRI brain were performed in selected cases. Azoospermic patients having hypogonadotropic hypogonadism were treated with long-acting testosterones and gonadotropins. OBSERVATION The study subjects were infertile azoospermic males. On the basis of serum FSH and testosterone levels, they were classified into two groups. Group A (n=42) cases were hypergonadotropic hypogonadism or primary testicular failure; of these 32 were Klinefelter syndrome (XXY), 7 chronic orchitis and 3 empty scrotal syndrome including one case of anorchia. These patients also developed other systemic illnesses in addition to hypogonadism. Group B (n=8) hypogonadotropic hypogonadism or secondary testicular failure; of these 2 were Kallman syndrome and the rest were idiopathic. After testosterone replacement all patients were virilized and there was marked improvement in libido and androgenization. CONCLUSION The study brings out that primary testicular failure is more common than secondary testicular failure. Both pattern of hypogonadism should receive lifelong androgen replacement therapy; otherwise, they will be a basket of multiple systemic disorders. Presently testosterone undecanoate once in every three months is the agent of choice.

Abstract
Aim The objective was to assess the correlation of fasting plasma glucose (FPG), HbA1c, and the duration of type 2 diabetes mellitus (T2DM) with SYNTAX score (SS) II in patients with non-ST elevation myocardial infarction (NSTEMI).Material and methods FPG and HbA1C were measured in 398 patients presenting with NSTEMI at admission. SS II was calculated using an online calculator. Patients were stratified according to SS II (≤21.5, 21.5-30.6, and ≥30.6), defined as SS II low, mid, and high, respectively.Results 37.7 % of subjects were diabetic. Correlations of FPG (R=0.402, R2=0.162, p<0.001) and HbA1c (R=0.359, R2=0.129, p<0.001) with SS II were weak in the overall population. Duration of T2DM showed very strong correlation with SS II (R=0.827, R2=0.347). For the prediction of high SS II in the study population, FPG≥98.5 mg / dl demonstrated a sensitivity of 58 % and a specificity of 60 %, and HbA1c ≥6.05 demonstrated a sensitivity of 63 % and a specificity of 69 %. Duration of T2DM (adjusted odds ratio (OR): 1.182; 95 % confidence interval (CI): 1.185-2.773) and FPG (OR: 0.987; 95 % CI: 0.976-0.9959) were significantly associated with high SS II after controlling for other risk factors. Duration of T2DM (Beta=0.439) contributed strongly to variance of SS II, whereas HbA1c (Beta=0.063) contributed weakly.Conclusion Duration of T2DM is a very important risk factor for severity of coronary artery disease.

Abstract
In this work, we have reported a noble metal free heterogeneous photocatalyst to carry out direct (het)arene C-H arylation and solvent-free CO2 capture via single-electron transfer processes at room temperature and under pressure. The catalytic system comprises a cobalt(III) complex grafted over the silica coated magnetic support for the efficient recovery of the photocatalytic moiety without hampering its light-harvesting capability. The novel Earth-abundant cobalt(III) based photocatalyst possesses various fascinating properties such as high surface area to volume ratios, large pore volume, crystalline behaviour, high metal loading, excellent stability and reusability. The general efficacy of the highly abundant and low-cost cobalt based heterogeneous nanocatalyst was checked for the selective conversion of aryldiazonium salts into synthetically and pharmaceutically significant biaryl motifs under ambient conditions upon irradiation with visible light. The highly efficient photocatalytic conversion of carbon dioxide (CO2) to a value-added chemical was accomplished under mild reaction conditions with high selectivity, showing the added benefit of operational simplicity.

Abstract
Cerebral malaria (CM) is one of the most severe forms of P. falciparum infection, with an associated high case-fatality rate. Angiopoietins (ANG-1 and ANG-2) are important biomarkers of endothelial activation and dysfunction. This study was carried out in Maharani Hospital and associated Medical College, Jagdalpur, CG, Central India from 2010 to 2014. Based on the treatment recovery patterns, cases (n = 65) were classified as mild malaria with rapid recovery (MM-RR), n= 14; non-cerebral severe malaria with moderately fast recovery (NCSM-MFR), n= 9; CM survivors with slow recovery (CMS-SR), n= 36 and deteriorated CM non-survivors (Det-CMNS), n= 6. Plasma levels (pg/ml) of ANG-1 and ANG-2 were measured by ELISA in all the samples at the time of hospital admission and 48 hours of treatment. Levels were also measured in available samples at the third time point (time of discharge for survivors or 72 hours post-treatment in fatal cases). Data analysis was done by appropriate statistical tests using Stata 11.0 and SPSS 25.0 software. At the time of admission, ANG-2 and ratios of ANG-2/ANG-1 significantly distinguished Det-CMNS cases from MM-RR and NCSM-MFR cases with good AUC scores (0.8-0.9). Further, Det-CMNS cases could also be distinguished from MM-RR, NCSM-MFR, and CMS-SR cases by ANG-2 (AUC scores 0.9) and ratios of ANG-2/ANG-1 (AUC: 0.8-0.9) at 48 hours of treatment. Paired analysis of sequential measurement of angiopoietins revealed that compared to admission levels, the ratios of ANG-2/ANG-1 significantly declined 48 hours after treatment in MM-RR (p= 0.041), NCSM-MFR (p= 0.050), and CMS-SR (p= 0.0002) cases but not in cases of Det-CMNS (p= 0.916). In conclusion, plasma levels of ANG-2 and ratios of ANG-2/ANG-1 may serve as good biomarkers to distinguish the malaria severity at the time of hospital admission and recovery patterns upon treatment in Central India.

Abstract
g-C3N4/Ca2Fe2O5 heterostructures were successfully prepared by incorporating g-C3N4 into Ca2Fe2O5 (CFO). As prepared g-C3N4/CFO heterostructures were initially utilized to photodegrade organic effluent Methylene blue (MB) for optimization of photodegradation performance. 50% g-C3N4 content in CFO composition showed an enhanced photodegradation efficiency (~ 96%) over g-C3N4 (48.15%) and CFO (81.9%) due to mitigation of recombination of photogenerated charge carriers by Type-II heterojunction. The optimized composition of heterostructure was further tested for degradation of Bisphenol-A (BPA) under direct sunlight, exhibiting enhanced photodegradation efficiency of about 63.1% over g-C3N4 (17%) and CFO (45.1%). The photoelectrochemical studies at various potentials with and without light illumination showed significant improvement in photocurrent response for g-C3N4/Ca2Fe2O5 heterostructures (~ 1.9 mA) over CFO (~ 67.4 μA). These studies revealed efficient solar energy harvesting ability of g-C3N4/Ca2Fe2O5 heterostructures to be utilized for organic effluent treatment.

Abstract
Breast implant-associated anaplastic large cell lymphoma (BIA-ALCL) is a rare but emerging T-cell non-Hodgkin lymphoma. It has two distinct subtypes, "effusion-only" or "mass-forming" disease, arising around implants in patients with in situ or previous history of textured-surface breast implants. The clinical, histopathological and imaging features are unique and nuanced as compared to primary breast malignancy and other lymphoma categories. Prompt recognition and diagnosis triggers referral to appropriate BIA-ALCL centres and initiation of treatment, with potential for excellent prognosis. Definitive management of both subtypes involves implant and capsule removal; systemic therapy is reserved for mass-forming disease and advanced-stage disease. There have been recent crucial advances in the diagnostic pathway, with publication of national and international guidelines: from the UK Medicines Healthcare products Regulatory Agency (MHRA) Plastic, Reconstructive and Aesthetic Surgery Expert Advisory Group (PRASEAG), and the United States National Comprehensive Cancer Network (NCCN). This review provides a practical guide to the clinical work-up of BIA-ALCL, enabling optimisation of the diagnostic imaging pathway, with representative cases.

Abstract
Proteinuria can range from subnephrotic to nephrotic amounts during pregnancy, though nephrotic syndrome (NS) is rare (0.012%-0.025%). Without a renal biopsy, this distinction may be difficult at times. The objective of our study was assessing about renal and feto-maternal outcomes of these patients. This study was done in a tertiary-care hospital in north India from 2010 to 2019. We included all pregnant women with nephrotic-range proteinuria, with no signs or symptoms suggestive of pre-eclampsia. We studied their treatment modalities, renal, maternal, and fetal outcomes. Eighteen eligible pregnant women diagnosed with NS with no features suggestive of pre-eclampsia or associated comorbidities were included. The gestational age of presentation was 23.2 ± 1.36 weeks. The average proteinuria was 4.38 ± 0.76 g/day. The patients were managed conservatively without kidney biopsy. About 16.7% of pregnancies had worsening of hypertension and acute kidney injury which recovered after delivery. Anasarca was troublesome for four patients requiring fresh-frozen plasma infusion. All were managed conservatively; however, five patients were started on empirical immunosuppression, all five with steroids, while two required the addition of calcineurin inhibitors as well. All had live births, but 25.7% each had preterm and intrauterine growth restriction while one required neonatal intensive care unit admission. The degree of proteinuria had an impact on maternal and fetal outcomes, especially on risk to pre-eclampsia. NS during pregnancy needs evaluation and counseling. Majority of them can be managed conservatively yet specific therapies can safely be tried among symptomatic ones. Despite good outcomes, a sizeable risk to maternal and fetal complications can occur.

Abstract
This research trial is aimed to study the nutritional qualities and significance of feeding spent marigold flower meal (SMFM) in goats. SMFM and diet containing iso-nitrogenous concentrate mixture with different levels of spent marigold flower meal (0-30%) were studied for in vitro degradation. Depending upon the in vitro results, concentrate mixture containing 15% level of SMFM was selected for in vivo trial. In vivo studies were conducted for a period of 60 days, and 12 local, non-descript, adult male goats (10-14 months age; 31.09 ± 2.91 kg body weight) were randomly assigned to two groups and were fed on ad libitum wheat straw with either conventional (control) or SMFM containing concentrate mixture (treatment). Results of the study showed that there was no variation in body weight of the goats between periods and between groups. DM and OM intake along with their digestibility were similar among the two groups. The digestibility of all other nutrients was comparable between the two groups. Nitrogen, calcium and phosphorus balance were positive in both the groups without any significant disparity. Moreover, experimental goats did not differ in biochemical parameters, without any significant difference between periods and dietary treatments except AST level which was significantly higher (P > 0.05) in treatment group. So, this study successfully demonstrates that SMFM could be incorporated in the concentrate mixture, up to 15% without any discernable difference in the performance of goats.

Abstract
OBJECTIVE We assessed the long-term survival of TB patients belonging to the Saharia tribe, a high TB burden community in Shivpuri district, Madhya Pradesh, central India. METHODS Population-based, longitudinal study conducted among 9756 Saharia population in 2013, and a resurvey done 2 years later in 2015 using the same methods. The status of the individuals during resurvey was recorded as non-TB, relapse and death. The deaths recorded in this period were used to measure the mortality among TB-affected population and the non-TB population in this cohort. RESULTS The standardised mortality ratio for the study cohort was 122.9 per 1000 population; males had higher mortality than females (129.9 vs. 96.8). The expected mortality among the non-TB population was 30.2, and the observed mortality among TB-affected population was 122.9 per 1000 population. CONCLUSION In the Saharia tribe, post-treatment mortality in the TB-affected population is significantly higher than in the general population. This highlights an urgent need for implementation of effective public health strategies to prevent disproportionate deaths among TB-affected individuals in resource-poor settings, and the importance of periodic follow-up of patients after cure/completion of treatment, especially in vulnerable populations.

Abstract
Chronic lymphocytic leukaemia (CLL) is the most common leukaemia in adults. It is a malignancy of CD5 B-cells characterised by small, mature-appearing lymphocytes accumulating in the blood, bone marrow, and lymphoid tissues. Richer transformation (RT) is an important adverse complication. Detection of RT is critical to allow initiation of appropriate therapy. CLL staging and response evaluation is complicated and nuanced. From our extensive tertiary centre experience of several hundred CLL cases over the last decade, we detail key computed tomography (CT) and positron-emission tomography (PET) imaging features of the natural history of CLL. The authors present an original imaging-based patient-management paradigm for the investigation of potential RT, which will inform global practice. Potential applications of whole-body diffusion weighted imaging, novel PET radiotracers, minimal residual disease, and ct-DNA are addressed.

Abstract
This study was designed to examine the effects of seminal insulin-like growth factor-1 (IGF-1) supplementation on structural and functional properties of buffalo sperm post cryopreservation. Semen ejaculates from buffalo bulls (n = 6) were proportioned into four aliquots and diluted with egg yolk-based extender. Prior to equilibration, IGF-1 was added to extender as four treatments: group IGF0 (no supplementation), IGF150 (150 ng/mL), IGF250 (250 ng/mL) and IGF350 (350 ng/mL). The extended semen was transferred into 0.25 mL mini-straws, equilibrated (4 °C at 4 h), and cryopreserved. Total sperm motility was greater (P < 0.05) when there was the IGF150 treatment compared with values for other groups. Furthermore, with the IGF150 treatment there was the least and greatest (P < 0.05) mitochondrial superoxide status and membrane potential, respectively. Similarly, with the IGF150 treatment there was a greater (P < 0.05) sperm membrane integrity with a lesser (P < 0.05) calcium status compared to values for the other groups. In conclusion, seminal IGF-1 supplementation affects the structural and functional properties of buffalo sperm following cryopreservation.

Abstract
Non-Hodgkin's lymphoma (NHL) encompasses over 40 different haematological malignancies, including low and high-grade neoplasms, such as follicular lymphoma (FL) and diffuse large B-cell lymphoma (DLBCL) respectively. A key clinical issue in the context of NHL is delayed and inaccurate diagnosis, which contributes adversely to patient morbidity and mortality. This article will address relevant imaging aspects, with particular reference to advancements in NHL imaging, including computed tomography (CT), integrated positron-emission tomography (PET)-CT, and magnetic resonance imaging (MRI). We provide multiparametric (anato-functional) imaging display items, including histological correlation. We will also introduce our original concept of "Specialist Integrated Haematological Malignancy Imaging Reporting" (SIHMIR), a paradigm shift in lymphoma radiology.

Abstract
Thrombotic microangiopathy (TMA) after kidney transplant is rather uncommon but an important reversible cause of graft loss. This retrospective study of biopsy-proven posttransplant TMA was done to identify the important etiological factors, clinical features, and outcomes of post transplant TMA in a tertiary care referral hospital in northern India. This retrospective study was conducted among all renal transplant recipients who presented with graft dysfunction between 1989 and 2015. All the cases were looked for their etiology, clinical course, treatment modalities, and renal outcomes. The study was conducted in accord with prevailing ethical principles and reviewed by our own institutional review board. Seventeen patients out of 2000 (0.008%) transplants done during the study period had posttransplant TMA, out of which all the patients had de novo TMA, and the median time of presentation after transplantation was four months. Systemic TMA was noted in only four patients. Biopsy revealed associated rejection in five patients and associated calcineurin inhibitor (CNI) toxicity in 12 patients. Patients with TMA due to CNI toxicity were managed with CNI reduction or switching to alternate CNI or mammalian target of rapamycin inhibitors. In addition, antithymocyte globulin and plasma exchange were used in rejection-associated TMA. While four out of 12 patients (33%) in CNI-related TMA developed end-stage renal disease (ESRD), all patients in rejection-associated TMA developed ESRD. The overall one-year graft survival was 47%, whereas five- and 10-year survival was 35%. There was no significant difference in graft survival between localized and systemic TMAs (P = 0.4). Posttransplant TMA should be suspected even if there are no systemic features of hemolysis and early graft biopsy and prompt action is needed. The occurrence of TMA in the setting of rejection is associated with grave prognosis.

Abstract
The photoabsorption spectroscopic studies (PASS) beamline (PASS-BL07), installed at a bending magnet 450 MeV, 100 mA Indus-1 synchrotron source (India), is capable of performing photoabsorption studies in the vacuum ultraviolet to soft x-ray range of thin films and solid samples. The beamline covers an energy range of 55 eV-840 eV by an in-house developed SX-700 type plane grating monochromator. This energy range will cover the absorption spectra of low Z-elements like C, N, and O as well as the L and M threshold of 3d elements such as Ti, V, S, etc. The beamline will be significantly used for studying organic semiconductors, graphene, etc. In this article, the design details of the beamline and some of the recent scientific results have been presented.

Abstract
Background: The effect of childhood well-being programs is commonly interconnected with a change in mortality trends. The proportion of disparity shows that inequality in child mortality is more collective in the similarly evolved states than the poorer states in India. Objective: To estimate and compare the health inequality of under-five mortality in Empowered Action groups (EAG) states of India. Methods: Data from the National Family Health Survey (NFHS-4) was used only for the EAG States of India. Under-five mortality rates (U5MR) were calculated for associated background characteristics by using the life table method. Wealth inequality was assessed separately for all EAG states by calculating measures of concentration index (CI). Concentration curves (CC) were also plotted to see the difference in inequality. Results: Higher U5MR was observed in all EAG states compared with estimates for overall India. On comparing estimates of inequality, CI values show the substantial burden of U5MR among EAG states of India. The CC shows the lowest inequality in EAG states of India. Conclusion: The results suggested the need to receive various health strategy intercessions in agreement with the instance of ever-changing commitments of economic components to child health disparities in EAG states. Measuring the impact of determinants to wealth-related inequality in U5MR helps in lining up the interventions targeted at improving child survival.

Abstract
Widespread of heavy metals contamination has led to several environmental problems. Some biological methods to remove heavy metals from contaminated wastewater are being widely explored. In the present study, the efficiency of a white-rot fungus, Phlebia brevispora to remove different metals (Pb, Cd and Ni) has been evaluated. Atomic absorption spectroscopy of treated and untreated metal containing water revealed that all the metals were efficiently removed by the fungus. Among all the used metals, cadmium was the most toxic metal for fungal growth. Phlebia brevispora removed maximum Pb (97·5%) from 100 mmol l-1 Pb solution, which was closely followed by Cd (91·6%) and Ni (72·7%). Scanning electron microscopic images revealed that the presence of metal altered the morphology and fine texture of fungal hyphae. However, the attachment of metal on mycelia surface was not observed during energy-dispersive X-ray analysis, which points towards the intracellular compartmentation of metals in vacuoles. Thus, the study demonstrated an application of P. brevispora for efficient removal of Pb, Cd and Ni from the metal contaminated water, which can further be applied for bioremediation of heavy metals present in the industrial effluent.

Abstract
Background: Majority of childhood poisonings are unintentional. The incidence of poisoning in children has been shown to be reduced by a significant amount. But to develop effective prevention strategies, the state health care planners need better information on the number and types of poisonings, circumstances in which they occur, and how serious the problem is. Objective: To study the clinical profile of poisoning in children. Methods: A hospital-based cross-sectional study was carried out among children aged 0–12 years with the history of poisoning. Detailed history, clinical examination, and details of poisoning was obtained. Data was analyzed using proportions. Results: Majority (77.8%) belonged to the age group of 1–5 years and were males (65.4%). Household chemicals were ingested in 83 cases out of 153, (54.25%) and in 147 cases (96.1%), poisonous substance was easily accessible to victim. In 144 out of 153 cases (94.1%), poisonous substance was accidentally ingested by the child itself, 131 out of 153 cases (85.6%) occurred at home, while 18 (11.8%) cases occurred in home surroundings. Of the 153 cases, 2 patients (1.3%) presented with the history of diarrhoea, 12 patients (7.8%) in altered sensorium, 6 patients (3.9%) had fever, 16 patients (10.5%) presented with cough, 37 patients (24.2%) presented with excessive secretions from mouth. 31 patients (20.3%) presented with vomiting without blood staining and 12 patients (7.8%) had blood stained vomiting as their chief complaint. Mucosal injury was noted in 41 cases (26.8%). Conclusion: Poisoning was common in males. Household chemical was most commonly ingested. Majority children had domestic poisoning and self-unintentional.

Abstract
Among various bone regenerative and repair methods, use of osteoinductive scaffold as bone grafts/substitute has gained wide importance worldwide. To develop such osteoinductive scaffold that is more natural and which spontaneously stimulates osteoblast formation without any differentiation media, we prepared electrospun poly ε-caprolactone scaffold which is further modified by means of layer-by-layer method using Cissus quadrangularis callus culture extract and graphene oxide (PCL-GO-CQ). The modified PCL-GO-CQ scaffold was compared with plain poly ε-caprolactone scaffold and poly ε-caprolactone coated only with graphene oxide. Physical properties, such as roughness, wettability, yield strength and tensile strength, of PCL-GO-CQ scaffold were found to be superior. Also, PCL-GO-CQ scaffold showed more in vitro cell compatibility with enhanced cellular proliferation on its surface. Presence of graphene oxide and Cissus quadrangularis callus in scaffold helped in the differentiation of human umbilical cord Wharton’s jelly-derived mesenchymal stem cells into osteogenic lineage without any differentiation media in less than 20 days. The synergistic effect of Cissus quadrangularis callus extract and graphene oxide in PCL-GO-CQ scaffold enhanced osteoblastic differentiation, osteoconduction and osteoinduction potential of scaffolds making them highly potential in bone regeneration and bone tissue engineering applications.

Abstract
In buffaloes, like other domestic mammals, antral follicles develop in a wave-like pattern. Factors predictive of a particular follicular wave pattern are yet to be identified. In this study, we examined the preponderance of 2- versus 3-wave patterns in 46 interovulatory intervals (IOIs) from 36 buffalo heifers, in which a subset of 10 heifers was scanned for 2 consecutive IOIs to record the repeatability of follicular wave pattern. Two-wave pattern was detected in 63.0% and 3-wave follicular pattern in 27.0% IOIs. The dominant follicles (DF) of both wave 1 as well as the ovulatory wave attained a smaller (P < 0.05) maximum diameter in 3-wave cycle as compared to 2-wave cycle. The mean duration of IOI was significantly shorter in 2-wave compared to three-wave cycles (20.5 ± 0.3 vs. 22.3 ± 0.2 days; P < 0.05). Out of 10 buffalo heifers, 7 displayed non-alternating patterns and 3 had alternating follicular wave patterns. We also tested the hypothesis that progesterone administration during early IOI results in increased preponderance of 3-wave pattern and heifers inseminated after ovulation of the third wave DF will have greater fertility. Sixteen heifers subjected to progesterone treatment from D0 (day of ovulation) in a decreasing dose until D5 were compared with control heifers (n = 10). Progesterone treatment significantly reduced the maximum diameter of DF of wave 1 (P < 0.001), whereas the mean duration of IOI remained unchanged (P > 0.05) between the two groups. Progesterone administration during early IOI significantly increased the proportion of 3-wave cycles as compared to control (P < 0.05). The hypothesis that progesterone administration during IOI results in increased preponderance of 3-wave pattern was supported. However, no change in fertility was recorded in progesterone-treated heifers (7 pregnant out of 16; 43.8%) as compared to untreated control heifers (4 out of 10 heifers; 40.0%). In summary, progesterone administration in buffalo heifers during the growing phase of wave 1 resulted in greater preponderance of 3-wave follicular patterns, with no significant effect on fertility.

Abstract
OBJECTIVE: The inhibitory potential and percent inhibition of Syzygium aromaticum oil and fresh juice of Ocimum sanctum leaves on beta-lactamase enzyme of cecal samples of healthy broilers were studied on samples phenotypically positive for extended-spectrum beta-lactamase (ESBL)-producing Escherichia coli. MATERIALS AND METHODS: Four hundred cecal samples screened for ESBL-producing E. coli were collected from 38 poultry sale outlets located in Jabalpur. The effect of S. aromaticum oil and O. sanctum leaves was seen by colorimetric assay with CENTA and Nitrocefin as chromogenic substrate. RESULTS: Mean absorbance value was inversely propotional to the inhibitory potential. Syzigium aromaticum exhibited 0.4±0.02 and 0.41±0.03 mean absorbance value, 28 per cent and 27 per cent of inhibition with CENTA and Nitrocefin respectively. Ocimum sanctum mean absorbance value and per cent inhibition with CENTA and Nitrocefin was 2.03±0.02 and 10.0 ; 1.97±0.06 and 10.0 respectively (p>0.05) showing non- significant difference in CENTA and Nitrocefin activity. Tazobactum (100 μM) as standard control exhibited a mean absorbance value of 0.12 ± 0.01 and 0.13 ± 0.01 and percent inhibition of 99.88 and 98 against CENTA and Nitrocefin, respectively. Combination of Ocimum sanctum and Syzigium aromaticum showed range of 1.69±0.05 to 1.90±0.08 1.61±0.06 to 1.92±0.08 of absorbance value with per cent inhibition of 14 to 15.9 with CENTA and Nitrocefin respectively. CONCLUSION: The results depicted that the inhibition of beta-lactamase enzyme activity with S. aromaticum oil was higher than that of O. sanctum leaf juice, and combination of both the herbs showed not much difference in activity.

Abstract
Reactivation of cytomegalovirus (CMV) and BK polyomavirus (BKV) can result in virus-associated tubulointerstitial nephritis in renal allografts. All those renal biopsies reported as viral cytopathic were isolated and examined by two independent renal histopathologists from our institute and classified as CMV, BKV, and CMV-BKV coinfection-associated viral cytopathic changes with confirmation through polymerase chain reaction technology in either serum or urine or both. All twenty patients were categorized as 10 in CMV, four in BKV, and six were in CMV-BKV coinfection. One patient each had received antithymocyte globulin and basiliximab as induction all patients received triple-drug immunosuppression. The mean graft survival was 69, 61, and 59 months in CMV, BKV, and CMV-BKV coinfection group, respectively. At the end of the study period, 10 (50%) patients died. 1-, 3-and 5-year patient survival was 94%, 88% and 76% among CMV group, 75%, 75% and 50% in BKV group, and 96%, 83% and 62%, in CMV-BKV coinfection group (P = 0.157). CMV and BK virus are not so common infections in postrenal transplant patients yet an important cause of graft dysfunction. Coinfection did not pose an increased risk for acute rejection or patients and death-censored and uncensored graft survival among compared groups.

Abstract
BACKGROUND Wheat is the most important staple crop in Afghanistan and accounts for the main part of cereal production. However, wheat production has been unstable during the last decades and the country depends on seed imports. Wheat research in Afghanistan has emphasized releases of new, high-yielding and disease resistant varieties but rates of adoption of improved varieties are uncertain. We applied DNA fingerprinting to assess wheat varieties grown in farmers' fields in four Afghan provinces. RESULTS Of 560 samples collected from farmers' fields during the 2015-16 cropping season, 74% were identified as varieties released after 2000, which was more than the number reported by farmers and indicates the general prevalence of use of improved varieties, albeit unknowingly. At the same time, we found that local varieties and landraces have been replaced and were grown by 4% fewer farmers than previously reported. In 309 cases (58.5%), farmers correctly identified the variety they were growing, while in 219 cases (41.5%) farmers did not. We also established a reference library of released varieties, elite breeding lines, and Afghan landraces, which confirms the greater genetic diversity of the landraces and their potential importance as a genetic resource. CONCLUSIONS Our study is the first in wheat to apply DNA fingerprinting at scale for an accurate assessment of wheat varietal adoption and our findings point up the importance of DNA fingerprinting for accuracy in varietal adoption studies.

Abstract
This paper describes the design, simulation, development, and analysis of a Cross Floating Valve (CFV), an important instrument used in a cross float or pressure calibration system of pressure balances (PBs) to make the calibration process easy and time efficient. The design aspects of the CFV include the selection of proper materials and modeling of various necessary components of the CFV. For the piston design, 5 different materials, SS304, SS316, Aermet 340, SS440C, and AISI17-4PH were used. After the design, simulation studies were carried out using the ANSYS (Workbench R15.0) software to understand the behavior of stress, strain, and deformation. Out of the 5 materials thus used, the values of the factor of safety of 2 materials (SS304 and SS316) were found to be below expectations and hence were not used in the fabrication process. Among the rest of the 3 other materials (AISI17-4PH, SS440C, and Aermet 340) having a factor of safety within the expected limits, Aermet 340 was also ignored because of its high cost. Finally, AISI17-4PH and SS440C were used to fabricate the piston, the most important and critical component of the CFV. The final CFV thus developed was tested for its performance in the cross floating experiments with 2 different sets of PBs. The results thus obtained show that the use of CFV reduces the calibration time considerably which is approximately 30% (average time of increasing and decreasing orders of pressure) from the time taken in performing calibration without using CFV, which is a significant achievement.

Abstract
More than 50% of patients with systemic lupus erythematosus (SLE) have renal involvement at presentation or during their illness. Lupus nephritis (LN) encompasses several patterns of renal disease, including glomerular, tubulointerstitial, and vascular pathologies. The presence and significance of renal vascular lesions (VLs) are often overlooked. VLs in LN are not rare with an incidence of 10%-40% on renal biopsies from various studies and their presence is often labeled as poor prognostic markers. The current treatment protocol for LN is mainly based on the glomerular pathology, and no guidelines/consensus exists for treatment of LN with VLs. We describe the clinical presentation, course, response to therapy, and outcomes in five patients with SLE with histological evidence of renal VLs.

Abstract
The objective of the study was to establish correlation of seminal and serum IGF-1 with seminal attributes, estimate antioxidant potential of IGF-1 by 2, 2-diphenyl-1-picrylhydrazyl (DPPH) and ferric reducing antioxidant power (FRAP) assays and to study the effect of IGF-1 supplementation on semen cryopreservation. For this study, buffalo bulls were divided into sub-fertile (n = 2) and normal (n = 5) on the basis of sperm mass motility and individual motility. The serum IGF-1 concentration of normal bulls was greater than in sub-fertile bulls, but there was no difference in the seminal IGF-1 concentration among the groups. The values from correlation analyses indicated that serum IGF-1 concentration is positively correlated with semen mass motility and sperm concentration. In the second experiment, IGF-1 did not have antioxidant activities when assessed with DPPH and FRAP assays. In the third experiment, the ejaculates of normal and sub-fertile bulls were cryopreserved using semen extender in which there was IGF-1 supplementation at 0 (control), 50, 100, 150, 200, 250, 350 and 450 ng/mL of extender. Supplementation of IGF-1 at 250 ng/ml resulted in improved sperm motility, longevity and membrane intactness as compared to control after cryopreservation of semen from normal buffalo bulls, but not sub-fertile bulls. In summary, serum IGF-1 concentration was correlated with sperm mass motility and concentration in buffalo bulls and supplementation of IGF-1 protected sperm during the cryopreservation process but effects were not due to direct antioxidant activity.

Abstract
INTRODUCTION Arteriovenous fistula is considered as gold standard access for maintenance hemodialysis. Due to increasing burden of end-stage renal disease requiring dialysis, it is important for nephrologists to complement creation of arteriovenous fistula to meet the demand. METHODS This retrospective study was designed to assess the outcomes of arteriovenous fistula made by nephrologists at a tertiary care center from North India. The study included all radiocephalic arteriovenous fistula performed by nephrologists between November 2015 and January 2017. All arteriovenous fistulas were performed in patients whose duplex ultrasonography revealed both arterial and venous diameter of at least 2 mm. Data were collected with regard to age, gender, dialysis status, basic diseases, co-morbidities, and mineral bone disease parameters. The predictors of the primary and secondary patency rates were analyzed. RESULTS Five hundred patients (age 39.3 ± 14.4 years; 82.4% males; 21.6% diabetics) were included. In total, 83 (16.6%) patients had primary failure and 31 (7%) patients had secondary failure. Diabetes was associated with poor primary and secondary patency rates. Mean survival among the patients without primary failure was 11 months. The primary patency rates at 3, 6, 12, 18, and 21 months were 82%, 78%, 73%, 70%, and 70%, respectively. CONCLUSION To conclude, the outcomes of radiocephalic arteriovenous fistulas created by nephrologists are at par with historic outcomes.

Abstract
Background In spite of an alarmingly high tuberculosis (TB) burden amongst the Saharia tribe of central India, there is hardly any study to investigate the impact of DOTS implementation on the magnitude of tuberculosis disease and the changes over time. This article present the findings of TB prevalence surveys conducted amongst this indigenous population in two different time periods to know the change in the prevalence of TB. Methods A cross sectional survey was conducted among Saharia population in Shivpuri district, Madhya Pradesh during February 2013 to May 2013 and resurvey during March 2015 to July 2015. All individuals (≥15 years) were examined for chest symptoms suggestive of TB. Sputum samples were collected from all presumptive TB cases and were confirmed by laboratory examination by Ziehl-Neelsen smear microscopy and solid media culture methods. All detected cases were referred to health facility for anti-tuberculosis treatment as per RNTCP guidelines. Results There was significant reduction (trend Chi square 19.97; OR = 1.521; p = 0.000) in the prevalence of TB at the endline (1995 per 100,000) as compared to baseline (3003 per 100,000). The reduction was significant among males as compared to females (OR 1.55; p = 0.000) and in the age group of 25–34 years (OR 2.0; p = 0.007) and 45–54 years (OR 4.39; p = 0.003). There was significant reduction in the prevalence in both smear (OR 1.29; p = 0.02) and culture positive (OR 1.57; p = 0.000) TB at the endline survey. Conclusion The study findings highlight a reduction in the prevalence of TB among Saharia tribal population. Further studies are needed to identify the factors associated with reduction in prevalence among this population and also further surveys to monitor the prevalence trend over a period.

Abstract
Buffaloes have tendency to show seasonal reproduction and remain in anestrus due to limited ovarian activity during summer. The seasonal reproductive behavior is ascribed the effect of melatonin related to photoperiod. Treating animals with melatonin could be a possible strategy to overcome the problem. The role of MTNR1A gene has not been fully explained in the buffalo. Therefore, we conducted a study on 114 buffalo heifers to detect the polymorphic site in MTNR1A gene and further treated them with melatonin implants to investigate the role of most frequent genotype following melatonin treatment on pregnancy. The present investigation is the first to investigate the association between melatonin treated different MTNR1A genotype buffalo and pregnancy. We confirmed SNP at position 72 in 812 bp fragment exon II of MTNR1A gene. RFLP of PCR products with Hpa I enzyme resulted in three genotypes: TT (812bp), CT (812, 743, 69bp) and CC (743, 69bp). Next, buffaloes of each genotype (TT, CC, CT; n = 28 for each) were treated with melatonin implants to compare the conception rate with their corresponding untreated control (n = 10 for each genotype). Melatonin concentrations were higher (P < 0.05) for the treatment groups of all genotypes compared to their respective untreated control from day 1-28. The pregnancy rate was significantly associated with the MTNR1A genotype. The conception rate was higher (P < 0.05) for TT genotype than for the other genotypes of buffaloes treated with melatonin. Furthermore, buffaloes of TT genotype treated with melatonin started exhibiting estrus activity soon from second week of melatonin treatment (14.1 ± 2.1; range: 10-17 days) and were found to be 7.8 times more likely to become pregnant compared to other genotypes following melatonin treatment. In conclusion, TT genotype of MTNR1A gene is more sensitive to melatonin treatment that favours pregnancy in buffaloes during summer.

Abstract
Early graft dysfunction after renal transplantation manifests as acute rejection (AR) or acute tubular necrosis (ATN). Blood oxygen level-dependent (BOLD) magnetic resonance (MR) imaging is a noninvasive method of assessing tissue oxygenation, which may be useful for predicting acute allograft dysfunction. This was a prospective study involving 40 patients scheduled for renal transplantation from August 2012 to August 2014. In addition, 15 healthy donors were also enrolled in this study. All recipients underwent BOLD MR imaging (MRI) and R2* mapping 10–20 days after transplant, and additionally within 48 h of biopsy if there was any evidence of graft dysfunction. The healthy donors underwent BOLD MRI 1–2 days before surgery. The biopsies were grouped into AR, ATN, and no evidence of AR or ATN. The mean medullary R2*, cortical R2*, corticomedullary gradient, and medullary: cortical R2* ratio were compared between groups using one-way analysis of variance. Spearman's correlation and multinomial linear regression were applied to determine the influence factors of R2* value. Overall, nine patients had graft dysfunction. Six were reported as AR, two as ATN, and one as no evidence of ATN or rejection. The mean medullary and cortical R2* were significantly higher in ATN group compared with AR and normal group, whereas the mean medullary and cortical R2* of AR group were significantly lower than normal group. The corticomedullary gradient of AR group was significantly lower compared with ATN and normal group. Medullary R2*:cortical R2* ratio was significantly lower in AR group compared with normal group. No significant difference was noted between the 15 donors and patients with normal graft function. R2* values on BOLD MRI are significantly decreased in AR allografts and increased in an early stage of ATN allografts, suggesting that BOLD MRI can become a valuable tool for discriminating between AR and ATN.

Abstract
Acute kidney injury (AKI) with evidence of hemolysis is associated with tropical infections. However, pigment-induced AKI can happen with relatively uncommon genetic causes of hemolytic anemia, i.e., glucose 6-phosphate deficiency (G6PD). We share our experience of three such patients whose clinical presentation was similar to jaundice, AKI with hemolysis with suspicion of thrombotic microangiopathy. On evaluation, all had a history of usage of anti-malarial and with G6PD estimation revealing deficient status even during the episode while other tests such as Coomb's test and bone marrow biopsy was normal in all three patients. The kidney biopsy revealed acute tubular necrosis with red blood cell casts and pigments in all the cases. All patients were managed conservatively and showed complete recovery. Thus in tropical countries G6PD deficiency although is not common, should be considered among patients who have received antimalarial drugs presenting as AKI and a detailed hemolytic work-up needs to be carried out as an important cause of preventable recurrent AKI in tropical countries.

Abstract
The Hard X-ray Photo-Electron Spectroscopy (HAXPES) beamline (PES-BL14), installed at the 1.5 T bending-magnet port at the Indian synchrotron (Indus-2), is now available to users. The beamline can be used for X-ray photo-emission electron spectroscopy measurements on solid samples. The PES beamline has an excitation energy range from 3 keV to 15 keV for increased bulk sensitivity. An in-house-developed double-crystal monochromator [Si (111)] and a platinum-coated X-ray mirror are used for the beam monochromatization and manipulation, respectively. This beamline is equipped with a high-energy (up to 15 keV) high-resolution (meV) hemispherical analyzer with a microchannel plate and CCD detector system with SpecsLab Prodigy and CasaXPS software. Additional user facilities include a thin-film laboratory for sample preparation and a workstation for on-site data processing. In this article, the design details of the beamline, other facilities and some recent scientific results are described.

Abstract
Introduction There is lack of information on the proportion of new smear—positive pulmonary tuberculosis (PTB) patients treated with a 6-month thrice-weekly regimen under Revised National Tuberculosis Control Programme (RNTCP) who develop recurrent TB after successful treatment outcome. Objective To estimate TB recurrence among newly diagnosed PTB patients who have successfully completed treatment and to document endogenous reactivation or re-infection. Risk factors for unfavourable outcomes to treatment and TB recurrence were determined. Methodology Adult (aged ≥ 18 yrs) new smear positive PTB patients initiated on treatment under RNTCP were enrolled from sites in Tamil Nadu, Karnataka, Delhi, Maharashtra, Madhya Pradesh and Kerala. Those declared “treatment success” at the end of treatment were followed up with 2 sputum examinations each at 3, 6 and 12 months after treatment completion. MIRU-VNTR genotyping was done to identify endogenous re-activation or exogenous re-infection at TB recurrence. TB recurrence was expressed as rate per 100 person-years (with 95% confidence interval [95%CI]). Regression models were used to identify the risk factors for unfavourable response to treatment and TB recurrence. Results Of the1577 new smear positive PTB patients enrolled, 1565 were analysed. The overall cure rate was 77% (1207/1565) and treatment success was 77% (1210 /1565). The cure rate varied from 65% to 86%. There were 158 of 1210 patients who had TB recurrence after treatment success. The pooled TB recurrence estimate was 10.9% [95%CI: 0.2–21.6] and TB recurrence rate per 100 person–years was 12.7 [95% CI: 0.4–25]. TB recurrence per 100 person–years varied from 5.4 to 30.5. Endogenous reactivation was observed in 56 (93%) of 60 patients for whom genotyping was done. Male gender was associated with TB recurrence. Conclusion A substantial proportion of new smear positive PTB patients successfully treated with 6 –month thrice-weekly regimen have TB recurrence under program settings.

Abstract
Background To determine the socio-economic risk factors for pulmonary tuberculosis (PTB) in the Saharia tribal community in Madhya Pradesh, Central India. Methods PTB cases detected during the year 2013-14 through a community active TB prevalence survey in the Shivpuri district, Madhya Pradesh were included in the study. For each case, three controls were selected randomly among the non-cases from the same village and the data on socio-economic risk factors were collected. Using logistic regression analysis, the risk factors for PTB disease were identified. Results A total of 220 cases and 660 controls participated in the study. Of the 13 risk factors studied, on multivariate analysis the risk of PTB was found to be significantly associated with malnutrition (adjusted odds ratio [AOR] 2.02 [95% confidence interval {CI} 1.46 to 2.79]), living in a kaccha (built of naturally occurring materials) house (AOR 2.72 [95% CI 1.44 to 5.11]) and tobacco smoking (mostly beedis; AOR 1.59 [95% CI 1.12 to 2.18]). Conclusions The findings highlight that malnutrition, poor living conditions in a Kaccha house (built of naturally occurring materials) and tobacco smoking are the major risk factors for PTB among Saharias, which need to be studied among other tribal populations in the country. There is a need to strengthen health and nutrition programmes in this community.
