ABSTRACT

The systematic identification of insertion/deletion (InDel) length polymorphisms from the entire lentil genome can be used to map the quantitative trait loci (QTL) and also for the marker-assisted selection (MAS) for various linked traits. The InDels were identified by comparing the whole-genome resequencing (WGRS) data of two extreme bulks (early- and late-flowering bulk) and a parental genotype (Globe Mutant) of lentil. The bulks were made by pooling 20 extreme recombinant inbred lines (RILs) each, derived by crossing Globe Mutant (late flowering parent) with L4775 (early flowering parent). Finally, 734,716 novel InDels were identified, which is nearly one InDel per 5,096 bp of lentil genome. Furthermore, 74.94% of InDels were within the intergenic region and 99.45% displayed modifier effects. Of these, 15,732 had insertions or deletions of 20 bp or more, making them amenable to the development of PCR-based markers. An InDel marker I-SP-356.6 (chr. 3; position 356,687,623; positioned 174.5 Kb from the LcFRI gene) was identified as having a phenotypic variance explained (PVE) value of 47.7% for earliness when validated in a RIL population. Thus, I-SP-356.6 marker can be deployed in MAS to facilitate the transfer of the earliness trait to other elite late-maturing cultivars. Two InDel markers viz., I-SP-356.6 and I-SP-383.9 (chr. 3; linked to LcELF3a gene) when tested in 9 lentil genotypes differing for maturity duration, clearly distinguished three early (L4775, ILL7663, Precoz) and four late genotypes (Globe Mutant, MFX, L4602, L830). However, these InDels could not be validated in two genotypes (L4717, L4727), suggesting either absence of polymorphism and/or presence of other loci causing earliness. The identified InDel markers can act as valuable tools for MAS for the development of early maturing lentil varieties.

ABSTRACT

Yellow mosaic disease (YMD) remains a major constraint in mungbean (Vigna radiata (L.)) production; while short-duration genotypes offer multiple crop cycles per year and help in escaping terminal heat stress, especially during summer cultivation. A comprehensive genotyping by sequencing (GBS)-based genome-wide association studies (GWAS) analysis was conducted using 132 diverse mungbean genotypes for traits like flowering time, YMD resistance, soil plant analysis development (SPAD) value, trichome density, and leaf area. The frequency distribution revealed a wide range of values for all the traits. GBS studies identified 31,953 high-quality single nucleotide polymorphism (SNPs) across all 11 mungbean chromosomes and were used for GWAS. Structure analysis revealed the presence of two genetically distinct populations based on ΔK. The linkage disequilibrium (LD) varied throughout the chromosomes and at r2 = 0.2, the mean LD decay was estimated as 39.59 kb. Two statistical models, mixed linear model (MLM) and Bayesian-information and Linkage-disequilibrium Iteratively Nested Keyway (BLINK) identified 44 shared SNPs linked with various candidate genes. Notable candidate genes identified include FPA for flowering time (VRADI10G01470; chr. 10), TIR-NBS-LRR for mungbean yellow mosaic India virus (MYMIV) resistance (VRADI09G06940; chr. 9), E3 ubiquitin-protein ligase RIE1 for SPAD value (VRADI07G28100; chr. 11), WRKY family transcription factor for leaf area (VRADI03G06560; chr. 3), and LOB domain-containing protein 21 for trichomes (VRADI06G04290; chr. 6). In-silico validation of candidate genes was done through digital gene expression analysis using Arabidopsis orthologous (compared with Vigna radiata genome). The findings provided valuable insight for marker-assisted breeding aiming for the development of YMD-resistant and early-maturing mungbean varieties.

ABSTRACT

Subramanian Kannan Serum thyroglobulin (Tg) and thyroglobulin antibody (TgAb) levels are used to monitor patients with differentiated thyroid cancer (DTC) after total thyroidectomy with or without radioiodine (RAI) ablation. However, they are also measured in patients who are treated with thyroid lobectomy (TL)/hemithyroidectomy (HT). Data on the levels of Tg and its trend in those undergoing TL/HT is sparse in India. We reviewed retrospective data of DTC patients who underwent TL/HT and were followed-up with postoperative Tg levels between 2015 and 2020. Out of 247 patients, 17 had undergone either TL or HT, which included papillary thyroid cancer ( n = 12), follicular thyroid cancer ( n = 4), and noninvasive follicular thyroid neoplasm with papillary-like nuclear features (NIFTP) in 1 patient. All patients with DTC had tumor size < 4 cm (T1/2, clinical N0, Mx). The median follow-up was 15 months (range, 1-125) and the median Tg level was 7.5 ng/mL (interquartile range [IQR]; 3.6, 7.5) and ranged from 0.9 to 36.7 ng/mL. The median thyroid-stimulating hormone (TSH) level was 2.03 IU/L (IQR; 1.21, 3.59) and it ranged from 0.05 to 8.54 IU/L. As of last follow-up, none of them underwent completion thyroidectomy; however, eight patients had a decline in Tg ranging from 8 to 64%, four patients had increase in Tg ranging from 14 to 145%, three patients had stable Tg, and one of them had an increase in TgAb titers. As per American Thyroid Association (ATA) response-to-treatment category, six patients had indeterminate response, five patients had biochemical incomplete response, four patients had excellent response, and two did not have follow-up Tg and TgAb levels. While absolute values of Tg were well below 30 ng/mL in almost all patients with HT/TL, the Tg trends were difficult to predict, and only 23% of patients were able to satisfy the criteria for "excellent response" on follow-up. We suggest keeping this factor in mind in follow-up and while counselling for HT in patients with low-risk DTC.

ABSTRACT

BACKGROUND AND AIMS: No meta-analysis has analysed efficacy and safety of semaglutide in metabolic-dysfunction associated fatty-liver disease (MAFLD). METHODS: Electronic databases were searched for RCTs involving people with MAFLD and/or type-2 diabetes (T2DM) receiving semaglutide. Primary outcome was to evaluate changes in alanine aminotransferase (ALT). Secondary outcomes were to evaluate alterations in other measures of NAFLD, glycaemia, lipids and adverse-events. RESULTS: Data from 4 RCTs (2115 patients) was analysed. A greater lowering with injectable semaglutide 0.4mg/0.5 mg once weekly was seen with regards to ALT [MD -3.89U/L (95%CI: -5.41 to -2.36); P < 0.01; I2 = 0%; 2050 patients], liver stiffness (fibroscan®) [MD -3.19 kPa (95%CI: -3.26 to -3.12); P < 0.01; 162 patients], steatosis [MD -13.40 dB/m (95%CI: 20.56 to -6.24); P < 0.01; 162 patients], triglycerides [MD -21.43 mg/dl (95% CI: 41.63 to -1.23); P = 0.04; I2 = 99%; 2050 patients], total cholesterol [MD -5.53 mg/dl (95% CI: -8.45 to -2.61); P < 0.01; I2 = 0%; 1888 patients], LDL-cholesterol [MD -3.55 mg/dl (95% CI: -5.87 to -1.23); P < 0.01; I2 = 0%; 1888 patients], percent-weight [MD -8.99% (95%CI: -14.64 to -3.34); P = 0.002; I2 = 100%; 2115 patient] and HbA1c [MD -0.77% (95%CI: 1.10 to -0.45); P = 0.002; I2 = 100%; 2115 patients]. Number of patients inadequate to comment on histopathologic measures of MAFLD. Occurrence of treatment-emergent adverse-events [RR 2.31 (95% CI: 0.76-7.06); P = 0.14; I2 = 82%] and severe adverse events [RR 1.07 (95%CI: 0.69-1.65); P = 0.77; I2 = 33%] were comparable. Adverse-events leading to trial discontinuation [RR 2.37 (95% CI: 1.33-4.22); P = 0.003; I2 = 24%], diarrhea [RR 2.05 (95%CI: 1.17-3.60); P = 0.01; I2 = 66%], nausea [RR 4.98 (95%CI: 3.23-7.67); P < 0.001; I2 = 0%] and vomiting [RR 3.90 (95%CI: 1.75-8.68); P < 0.01; I2 = 54%] were higher with semaglutide. CONCLUSION: This meta-analysis provides reassuring data on efficacy of low dose semaglutide injections in improving ALT and certain radiologic features in MAFLD. Current conclusions are limited by small number of patients evaluated. Urgent need remains for larger studies focussing on liver biopsy.

ABSTRACT

Ultrasound-guided fine needle aspiration cytology (FNAC) is the preferred method of identifying malignancy in palpable thyroid nodules using the Bethesda reporting system. However, in around 30-40% of FNACs (Bethesda categories III, IV, and V), the results are indeterminate and surgery is required to confirm malignancy. Out of those who undergo surgery, only 10-40% of patients in these categories are found to have malignancies, thus proving surgery to be unnecessary for some patients or to be incomplete in others. While molecular testing on thyroid FNAC material is part of the American Thyroid Association (ATA) guidelines in evaluating thyroid nodules, it is currently unavailable in India due to cost constraints. In this study, we prospectively collected FNAC samples from sixty-nine patients who presented with palpable thyroid nodules. We designed a cost-effective next-generation sequencing (NGS) test to query multiple variants in the DNA and RNA isolated from the fine needle aspirate. The identification of oncogenic variants was considered to be indicative of malignancy, and confirmed by surgical histopathology. The panel showed an overall sensitivity of 81.25% and a specificity of 100%, while in the case of Bethesda categories III, IV, and V, the sensitivity was higher (87.5%) and the specificity was established at 100%. The panel could thereby serve as a rule-in test for the diagnosis of thyroid cancer and therefore help identify patients who require surgery, especially in the indeterminate Bethesda categories III, IV, and V.

ABSTRACT

The goal of this research was to remove COD, oil and grease (O&G) and color from raw ayurvedic hospital wastewater (AHWW) using a novel electrochemical coagulation (ECC) process. Cell voltage was initially optimized using iron electrodes in bipolar mode for both raw AHWW and ayurvedic hospital therapy room wastewater (AH-TRWW) for a pre-optimized electrolysis time (ET) of 60 min. O&G, COD and color removals for AHWW at 8 V optimized cell voltage were 96, 61 and 96% respectively. Different electrode materials, copper, aluminum, graphite, were used to evaluate relative performances at 8 V. Iron electrodes showed maximum pollutant removal from raw AHWW. The sludge obtained after the ECC process showed good settling and filterability properties compared to graphite and aluminum electrodes. The low SVI value of 146 mL/g was obtained exercising absolute control on sludge volume. Solids flux values showed assurances of compact settling tank design with least spatial footprint. EDX analysis for ECC sludge of AHWW using iron showed gross elements 40.19% C, 48.63% O and 7.92% Fe redefining the fate of sludge. The XRD pattern of the ECC sludge showed an amorphous nature. Post-ECC filtration effluent showed clear water reclamation of 80-82%, proving the effectiveness of the novel ECC treatment process.

ABSTRACT

Free-piston engine generators (FPEGs) have huge potential to be the principal energy conversion device for generating electricity from fuel as part of a hybrid-electric vehicle (EV) powertrain system. The principal advantages lay in the fact that they are theoretically more efficient, more compact, and more lightweight compared to other competing EV hybrid and range-extender solutions (internal combustion engines, rotary engines, fuel cells, etc.). However, this potential has yet to be realized. This article details a novel dual-piston FPEG configuration and presents the full layout of a system and provides technical evidence of a commercial FPEG system's likely size and weight. The work also presents the first results obtained from a project which set-out to realize an operational FPEG system in hardware through the development and testing of a flexible prototype test platform. The work presents the performance and control system characteristics, for a first of a kind system; these show great technical potential with stable and repeatable combustion events achieved with around 700 W per cylinder and 26% indicated efficiency.

ABSTRACT

BACKGROUND: Diabetes is a psychologically challenging medical condition. Diabetes distress (DD) refers to the unique, often hidden emotional burdens and worries that the patient experiences when managing diabetes. OBJECTIVE: The objective of the study was to find the burden and identify the predictors of DD in adult Type 2 diabetes mellitus (T2DM) patients. MATERIALS AND METHODS: Two hundred and fifty T2DM patients were recruited for this study from the endocrine outpatient department from February to April 2019. DD was measured using the Diabetic Distress Scale. RESULTS: The prevalence of DD was 19.6%. The risk of DD was 4.25 times more in those aged ≤45 years as compared to those aged >45 years. Patients with hemoglobin A1c (HbA1c) >8% had 8.8 times more DD. Patients on insulin had more DD (5.4 times) as compared to patients who were on oral antidiabetic drugs. Patients with a history of treatment interruption had 11 times more risk of DD as compared to patients who did not. CONCLUSIONS: DD was found to be high among patients aged ≤45 years, illiterates, patients on insulin, patients with a history of treatment interruption, and those with HbA1c >8%. Patients with high DD were found to have higher HbA1c levels.

ABSTRACT

UNLABELLED: The bacterial strain designated as WGR-UOM-BT1 isolated from rhizosphere of Rauwolfia serpentina exhibited broad-spectrum antifungal activity and also improved early plant growth. Based on morphological, biochemical and 16S rRNA gene sequence analyses, the strain BT1 was identified as Delftia tsuruhatensis (KF727978). Under in vitro conditions, the strain BT1 suppressed the growth of wide range of fungal phytopathogens. Purified antimicrobial metabolite from the strain BT1 was identified as nitrogen-containing heterocyclic compound, 'amino(5-(4-methoxyphenyl)-2-methyl-2-(thiophen-2-yl)-2,3-dihydrofuran-3-yl)methanol' (AMTM), with molecular mass of 340•40 and molecular formula of C17 H19 NO3 S. The strain BT1 was positive for rhizosphere colonization (tomato), IAA production, 1-aminocyclopropane-1-carboxylate (ACC) deaminase activity and phosphate solubilization. Under laboratory and greenhouse conditions, the strain BT1 promoted plant growth and suppressed foliar and root fungal pathogens of tomato. Therefore, antimicrobial and disease protection properties of strain BT1 could serve as an effective biological control candidate against devastating fungal pathogens of vegetable plants. Besides, the production of IAA, P solubilization and ACC deaminase activity enhance its potential as a biofertilizer and may stabilize the plant performance under fluctuating environmental conditions. SIGNIFICANCE AND IMPACT OF THE STUDY: In this study, we reported that Delftia tsuruhatensis WGR-UOM-BT1 strain has the plant growth promotion activities such as rhizosphere colonization (tomato), IAA production, 1-aminocyclopropane-1-carboxylate (ACC) deaminase activity and phosphate solubilization. This bacterial strain was found producing an antimicrobial nitrogen-containing heterocyclic compound identified as 'amino(5-(4-methoxyphenyl)-2-methyl-2-(thiophen-2-yl)-2,3-dihydrofuran-3-yl)methanol' [C17 H19 NO3 S] (AMTM), which is new to the bacterial world.

ABSTRACT

Ovotesticular disorder of sexual differentiation (OTDSD) is a rare cause of disorder of sexual differentiation predominantly having 46,XX karyotype, female phenotype and ambiguous genitalia. We report a 15-year-old having male body habitus, axillary and pubic hair, well-developed penis and right-descended testis with history of penoscrotal hypospadias correction, presenting with three episodes of cyclical haematuria, who biochemically had normal serum testosterone (338 ng dl(-1) ) which increased following hCG stimulation (614 ng dl(-1) ), elevated estradiol (17.35 pg ml(-1) ) along with elevated luteinising hormone (11.3 mIU l(-1) ) and follicle-stimulating hormone (31 mIU l(-1) ). Ultrasonography followed by micturating cystourethrogram and cystoscopy confirmed the presence of prostate, uterus, cervix and vagina draining into the urogenital sinus continuing till the penile urethra and left intra-abdominal gonad. Patient underwent hysterectomy and left gonadectomy. Histopathologic study of resected gonad confirmed presence of ovotestis. Low estradiol (1.2 pg ml(-1) ) following gonadectomy confirmed the ovotestis origin of estradiol. Chromosomal analysis revealed complex karyotype predominant being 47,XYY (50%) followed by 46,XY (26%) and 45,X (24%). This is perhaps the first report of 47,XYY/46,XY/45,X causing OTDSD in a phenotypic male.

ABSTRACT

Rathke's cleft cysts (RCC) are cystic sellar and suprasellar lesions derived from remnants of Rathke's pouch, lined by cuboidal or columnar epithelium. RCC are usually asymptomatic but can present with headache, visual impairment, panhypopituitarism and hypothalamic dysfunction. Diabetes Insipidus as a presenting symptom of RCC is reported, but rare. We present a case of a 48-year-old male presenting with polyuria and on investigations found to have central diabetes insipidus due to a sellar RCC. Patient underwent transsphenoidal surgery with complete excision with resolution of his symptoms. His polyuria resolved post-surgery without vasopressin replacement, which has never been reported.

ABSTRACT

Juvenile primary hypothyroidism causing cystic ovaries and pseudoprecocious puberty (Van-Wyk Grumbach syndrome (VWGS)) is well documented in literature. There are only a few reports of primary hypothyroidism presenting as ovarian cysts in adults. Here we present a case of huge bilateral ovarian cysts in adulthood as the presenting feature of VWGS due to chronic uncontrolled juvenile hypothyroidism. Large uniloculor right ovarian cyst (119 × 81 × 90 mm) and a multicystic left ovary (55 × 45 × 49 mm) were detected in a 24 year lady with secondary amenorrhea, galactorrhea, and palpable abdominal mass with history of neonatal jaundice, delayed milestones, short stature, and precocious menarche at age of 7.5 years age. She had elevated levels of cancer antigen (CA)-125 which normalized post levothyroxine supplementation. Elevated CA-125 may lead to misdiagnosis of ovarian carcinoma and inadvertent treatment. Bilateral ovarian cysts in adults are a rare presentation of juvenile hypothyroidism. It is necessary to screen for primary hypothyroidism in patients presenting with bilateral ovarian cysts to prevent unnecessary evaluation and treatment.

ABSTRACT

Emphysematous pyelonephritis (EPN) is a life-threatening condition most commonly observed in diabetes, with nephrectomy believed to be the treatment of choice. However, nephrectomy in EPN is associated with increased risk of complications secondary to associated hemodynamic instability and may result in lifelong hemodialysis in case of bilateral EPN. We present three patients of severe bilateral EPN and one patient of unilateral EPN with diabetic ketoacidosis (DKA) successfully managed conservatively. Patient 1 (severe bilateral EPN) and patient 4 (unilateral EPN with DKA) responded to aggressive broad spectrum antibiotics, whereas patients 2 and 3 (severe bilateral EPN) responded to broad spectrum antibiotics along with percutaneous catheter drainage (PCD). PCD resulted in initial drainage of 300 and 200 ml of pus, respectively. All patients had associated uncontrolled hyperglycemia, poor glycemic control (HbA1c >8.5%), prerenal and intrinsic renal failure, leukocytosis, and dyselectrolytemia which responded to aggressive supportive management and insulin. There are several reports of successful medical management of severe bilateral EPN. Nephrectomy might no longer be the preferred treatment of severe bilateral EPN and may be reserved for patients' refractory to antibiotics and PCD. Urgent randomized controlled trials are warranted in EPN to optimize the treatment protocols.

ABSTRACT

Newly synthesized ligand [2-((3-(benzyloxy)pyridin-2-ylimino)methyl)phenol] (Bpmp) react with manganese(II) to form mononuclear complexes [Mn(phen)(Bpmp)(CH3COO)(H2O)]·4H2O (1), (phen=1,10-phenanthroline) and [Mn(Bpmp)2(CH3COO)(H2O)]·5H2O (2). These complexes were characterized by elemental analysis, IR, (1)H NMR, Mass, UV-vis spectral studies. Molar conductance and thermogravimetric analysis of these complexes were also recorded. The in vitro SOD mimic activity of Mn(III) complexes were carried out and obtained with good result. The DNA-binding properties of the complexes 1 and 2 were investigated by UV-spectroscopy, fluorescence spectroscopy and viscosity measurements. The spectral results suggest that the complexes 1 and 2 can bind to Calf thymus DNA by intercalation mode. The cleavage properties of these complexes with super coiled pUC19 have been studied using the gel electrophoresis method, wherein both complexes 1 and 2 displayed chemical nuclease activity in the absence and presence of H2O2 via an oxidative mechanism. All the complexes inhibit the growth of both Gram positive and Gram negative bacteria to competent level. The MIC was determined by microtiter method.

ABSTRACT

Primitive neuroectodermal tumor (PNET) of adrenal is an extremely rare tumor of neural crest origin. A nonfunctional left adrenal mass (14.6 × 10.5 × 10.0 cm) on computed tomography (CT) was detected in a 40-year-old lady with abdominal pain, swelling, and left pleural effusion. She underwent left adrenalectomy and left nephrectomy with retroperitoneal resection. Histopathology revealed sheets and nest of oval tumor cells with hyperchromatic nuclei, prominent nucleoli, scanty cytoplasm, brisk mitotic activity, necrosis, lymphovascular invasion, capsular invasion, and extension to the surrounding muscles; staining positive for Mic-2 (CD-99 antigen), vimentin, synaptophysin, and Melan-A. Thoracocentesis, pleural fluid study, and pleural biopsy did not show metastasis. She responded well to vincristine, adriamycin, and cyclophosphamide followed by ifosfamide and etoposide (IE). This is the first report of adrenal peripheral PNET (pPNET) from India. This report intends to highlight that pPNET should be suspected in a patient presenting with huge nonfunctional adrenal mass which may be confused with adrenocortical carcinoma.

ABSTRACT

Cushing's syndrome (CS) is common after oral steroid use and has also been reported following topical or inhaled use, but it is extremely uncommon after intranasal administration. In this paper, we present the case of a child who developed CS after intranasal application of combined moxifloxacin-dexamethasone eye drops for epistaxis for a period of 3 months. CS caused by ocular preparations of steroids has not been reported previously. This case report highlights the fact that even eye drops can contain high doses of steroids and can lead to CS especially in children and especially if used intranasally. Ocular steroid drops should not be used intranasally. To minimize gastrointestinal absorption and therefore the risk of CS, nasal sprays should be preferred over nasal drops for intranasal steroid application.

ABSTRACT

INTRODUCTION: Allgrove's syndrome is a rare autosomal-recessive disorder with only about 70 cases reported thus far and is characterized by alacrima, achalasia, and ACTH insensitivity among other clinical features. However, it has a widely variable clinical presentation, which may result in such cases remaining undiagnosed. OBJECTIVE: To report a patient with impending Allgrove's syndrome and to highlight the importance of clinical suspicion in diagnosing the same. MATERIALS AND METHODS: A 2.5-year-old girl was diagnosed with impending Allgrove's syndrome on the basis of clinical presentation, barium swallow study, Schirmer's test, and hormonal evaluation. RESULTS: A 2.5-year-old girl, born of non-consanguineous marriage, presented with failure to thrive and developmental delay with occasional vomiting on taking solid or semi-solid food for past 6 months. Examination revealed stunted weight (SDS of -4.4) and height (SDS of -4.76), and barium swallow showed presence of achalasia. On direct questioning, her mother mentioned presence of decreased tears on crying since birth, and Schirmer's test confirmed the presence of dry eyes. Baseline ACTH was slightly elevated with normal basal and post-ACTH stimulation serum cortisol. Based on these findings, impending Allgrove's syndrome was diagnosed with a plan for follow-up study of adrenal function. CONCLUSIONS: Allgrove's syndrome may be an under diagnosed disorder as aclarima is often overlooked. However, a high index of clinical suspicion may help in avoiding adrenal crisis by diagnosing the condition early.

ABSTRACT

BACKGROUND: Familial glucocorticoid deficiency (FGD) is a rare autosomal recessive disorder characterized by glucocorticoid deficiency, high ACTH levels and normal mineralocorticoid levels. FGD is caused due to defects in adrenocorticotropic hormone (ACTH) signaling. The defect can be caused by mutations in genes encoding the ACTH receptor (melanocortin 2 receptor) or its accessory protein. PATIENTS: Here we report three siblings with FGD. The second in order of siblings presented at an age of 15 years with history of diffuse hyperpigmentation since childhood. Their parents were non consanguineous. The patients were hyperpigmented and taller compared with their parents. None of the siblings had ambiguous genitalia or neurological abnormalities. There was no history of tuberculosis in the family. Biochemical investigations revealed low serum cortisol (<1 µg/dl) and elevated plasma ACTH (>1250 pg/ml). Serum electrolytes, aldosterone, and plasma renin activity was normal. Based on the above mentioned data, a provisional diagnosis of FGD was made after ruling out the common causes of glucocorticoid deficiency. CONCLUSION: FGD is a rare autosomal recessive disorder which causes isolated glucocorticoid deficiency. Unawareness about the condition may lead to delayed diagnosis and treatment, which are associated with high rates of morbidity and mortality. Once a diagnosis is made it is easily treatable.
