Abstract
OBJECTIVE To determine risk-reducing early salpingectomy and delayed oophorectomy (RRESDO) acceptability and effect of surgical prevention on menopausal sequelae/satisfaction/regret in women at increased ovarian cancer (OC) risk. DESIGN Multicentre, cohort, questionnaire study (IRSCTN:12310993). SETTING United Kingdom (UK). POPULATION UK women without OC ≥18 years, at increased OC risk, with/without previous RRSO, ascertained through specialist familial cancer/genetic clinics and BRCA support groups. METHODS Participants completed a 39-item questionnaire. Baseline characteristics were described using descriptive statistics. Logistic/linear regression models analysed the impact of variables on RRESDO acceptability and health outcomes. MAIN OUTCOMES RRESDO acceptability, menopausal sequelae, satisfaction/regret. RESULTS In all, 346 of 683 participants underwent risk-reducing salpingo-oophorectomy (RRSO). Of premenopausal women who had not undergone RRSO, 69.1% (181/262) found it acceptable to participate in a research study offering RRESDO. Premenopausal women concerned about sexual dysfunction were more likely to find RRESDO acceptable (odds ratio [OR] = 2.9, 95% CI 1.2-7.7, P = 0.025). Women experiencing sexual dysfunction after premenopausal RRSO were more likely to find RRESDO acceptable in retrospect (OR = 5.3, 95% CI 1.2-27.5, P < 0.031). In all, 88.8% (143/161) premenopausal and 95.2% (80/84) postmenopausal women who underwent RRSO, respectively, were satisfied with their decision, whereas 9.4% (15/160) premenopausal and 1.2% (1/81) postmenopausal women who underwent RRSO regretted their decision. HRT uptake in premenopausal individuals without breast cancer (BC) was 74.1% (80/108). HRT use did not significantly affect satisfaction/regret levels but did reduce symptoms of vaginal dryness (OR = 0.4, 95% CI 0.2-0.9, P = 0.025). CONCLUSION Data show high RRESDO acceptability, particularly in women concerned about sexual dysfunction. Although RRSO satisfaction remains high, regret rates are much higher for premenopausal women than for postmenopausal women. HRT use following premenopausal RRSO does not increase satisfaction but does reduce vaginal dryness. TWEETABLE ABSTRACT RRESDO has high acceptability among premenopausal women at increased ovarian cancer risk, particularly those concerned about sexual dysfunction.

Abstract
Stanniocalcin-1 (STC1) is secreted by the variety of tissues having a major role in the regulation of calcium ions in the involuting mammary gland. The present work aims to sequence and structural characterization as well as expression profiling of STC1 gene in buffalo. Polymorphism identified in the 3-untranslated region (UTR) was analysed by polymerase chain reaction restriction fragment length polymorphism (PCR-RFLP) genotyping in riverine and swamp buffaloes. Expression profiling of STC1 was performed in different lactation stages of mammary gland and peripheral blood mononuclear cells to study the impact of 3'-UTR polymorphism on its expression. Different polymorphic sites were detected in the entire coding and noncoding regions of riverine and swamp buffaloes, including two INDELs. An identified polymorphic nucleotide locus A324G, having target sites for two miRNAs, namely bta-miR-2382 and bta-miR-1343, reported in cattle, was genotyped by PCR-RFLP to reveal variable allelic distribution among swamp and riverine buffaloes. Gene expression profiling across buffalo mammary tissues representing different lactation stages showed maximum expression of the STC1 gene in the involuting mammary gland. Ruminants' specific genetic variation has been observed in STC1 and its implication in buffalo mammary gland involution as well as coregulation of gene expression through miRNA binding in the 3'-UTR is suggested.

Abstract
The ability to generate induced pluripotent stem cells from differentiated cell types has enabled researchers to engineer cell states. Although studies have identified molecular networks that reprogram cells to pluripotency, the cellular dynamics of these processes remain poorly understood. Here, by combining cellular barcoding, mathematical modeling, and lineage tracing approaches, we demonstrate that reprogramming dynamics in heterogeneous populations are driven by dominant “elite” clones. Clones arise a priori from a population of poised mouse embryonic fibroblasts derived from Wnt1-expressing cells that may represent a neural crest–derived population. This work highlights the importance of cellular dynamics in fate programming outcomes and uncovers cell competition as a mechanism by which cells with eliteness emerge to occupy and dominate the reprogramming niche.

Abstract
Introduction Septoplasty or septal reconstruction is a corrective surgical procedure performed to straighten the nasal septum. It may be associated with numerous complications. To minimize these complications, both nasal cavities are frequently packed with different types of nasal packing. Materials and Methods This prospective, observational, and comparative study was undertaken in the Department of ENT, Rajindra Hospital, Patiala, Punjab, India. A total of sixty patients fulfilling the inclusion criteria participated in the study. They were divided into two groups, Groups A and B. After septoplasty, the nasal cavity was packed with gloved Merocel® in Group A and ungloved Merocel® in control group (Group B). The efficacy and patient tolerance for both nasal packings were compared and assessed. The data collected were compiled and analyzed statistically. Results In our study, it was demonstrated that gloved Merocel® produces less pain during pack insertion (P = 0.001) and produces less pain while insertion of pack in situ (P = 0.001) and during pack removal (P = 0.001). Saccharin transit time (STT) returned back to normal in gloved Merocel® group (P = 0.001) in most of patients (27) by the 2nd week, whereas STT in ungloved Merocel® group returned back to normal by the 4th week postoperatively. The differences in impairment in STT between the two groups were found to be statistically significant. There was no statistical significance between both groups for other parameters. Conclusion Gloved Merocel® may be preferred over ungloved Merocel® as nasal packing following septoplasty since both types of packs had similar hemostatic, adhesion prevention properties and similar incidence in postoperative complications and gloved Merocel® produces less pain during its insertion, while it is in situ, during its removal with early recovery of nasal mucociliary clearance mechanism of nose.

Abstract
Single-cell genomics has recently emerged as a powerful tool for observing multicellular systems at a much higher level of resolution and depth than previously possible. High-throughput single-cell RNA sequencing techniques are able to simultaneously quantify expression levels of several thousands of genes within individual cells for tens of thousands of cells within a complex tissue. This has led to development of novel computational methods to analyze this high-dimensional data, investigating longstanding and fundamental questions regarding the granularity of cell types, the definition of cell states, and transitions from one cell type to another along developmental trajectories. In this perspective, we outline this emerging field starting from the "input data" (e.g., quantifying transcription levels in single cells), which are analyzed to define "identities" (e.g., cell types, states, and key genes) and to build "interactions" using models that can infer relations and transitions between cells.

Abstract
IgG4-related disease (IgG4-RD) is a multisystemic mass forming immune-mediated disease entity, commonly creating confusion and diagnostic challenges. We present a case of a 25-year-old female who presented with bilateral orbital masses, lymphadenopathy, paraspinal and renal masses, which clinicoradiologically simulated lymphoma. The lymph node biopsy revealed interfollicular sheets of plasma cells creating confusion with Castleman's disease and marginal zone lymphoma. The orbital biopsy revealed ductular destruction, periductular plasma cells, and fibrosis, mimicking Sjogren's syndrome and Castleman's disease. However, the correlation of the clinical features with histopathological findings, IgG4 immunopositivity, and serum studies helped in clinching the diagnosis. This case presents an uncommon combination of clinical features infrequently reported in literature. Furthermore, and more importantly, it highlights the need to keep a differential of IgG4-RD in mind, to aid early and correct treatment of the disease.

Abstract
Nucleotide-binding oligomerization domain (NOD)-like receptor 2 is one of the important mediators of innate as well as adaptive immune response to microbial infections. In this study, NOD-like receptor-2 was characterized by determining the full gene sequence and analyzing genetic diversity in Indian buffaloes. Sequence analysis of buffalo NOD2 revealed 3042 nucleotides long ORF, encoding 1013 amino acids from 12 exons. Domain structure analysis indicated existence of 8 leucine-rich repeat (LRR) domains in buffalo, cattle, sheep and mouse, along with central NACHT/NOD domain and two N-terminal CARD domains. Comparative sequence analysis among different buffalo breeds identified 46 polymorphic sites in NOD2 gene. Among coding region SNPs, 10 were non-synonymous, 7 synonymous and 3 were present in 5'UTR. Genotyping of two nsSNPs, revealed significant differences in the allele frequencies, distinguishing swamp and riverine buffaloes, having different utilities. Association analysis with mastitis in dairy buffaloes indicated significant variation in allelic frequencies at G1135A locus, between mastitis affected and non-affected animals. Further, NOD2 gene expression was quantified in different riverine buffalo tissues, using real-time PCR and lymph node displayed highest expression, compared to others organs included in the study. Overall, the study revealed buffalo NOD2 gene attributes, important to understand species specific immune response in ruminants.

Abstract
The effect of FecB mutation on the gene expression in FecB carrier and noncarrier estrous synchronized ewes, has been analyzed. For this study the whole ovarian tissues and Graafian follicles were collected from estrus synchronized FecB carrier Garole, and non-carrier Deccani Indian sheep, showing remarkable differences in the numbers of preovulatory follicles among two groups. Eleven potential candidate genes (BMP15, GDF9, BMP4, BMP7, BMPR1B, BMPR1A, SMAD9, LHCGR, FSHR, IGF1R, and STAT5) were selected for their expression analysis by SybrGreen based real-time PCR, across ovaries and Graafian follicles of different fecundity groups, for having better insights into the effect of FecB genotypes on follicular development. Variable expression was observed for almost all the genes included in the present study among high and low fecundity groups that was most significant for the BMP7, BMP4, LHCGR, and FSHR transcripts in the ovarian follicles of high and low fecundity ewes, indicating their importance in governing the fecundity in FecB carrier, Indian Garole sheep. BMP4 expression among the genes studied was significantly higher in FecB carrier Garole sheep. This study confirms the changes in mRNA expression of the genes implicated in follicular development in FecB carrier and noncarrier Indian sheep breeds.

Abstract
SETTING High-resolution melting curve analysis (HRMA) can be used to screen for mutations in genes without the need for specific probes, with low turnaround time and high cost-effectiveness. OBJECTIVE To detect the sensitivity and specificity of a line-probe assay (LPA) and HRMA in comparison with BACTEC™ MGIT™ 960 for the detection of rifampicin (RMP) resistance. DESIGN A total of 219 Mycobacterium tuberculosis isolates tested by MGIT 960 for RMP susceptibility were tested with HRMA and LPA. Discordant samples were processed for sequencing of the RMP resistance-determining region (RRDR) of the rpoB gene. RESULTS HRMA identified 93 of 103 (90.3%) isolates that were resistant and 113/116 (97.4%) that were susceptible on MGIT 960, with a sensitivity and specificity of respectively 90.3% and 97.4%. HRMA identified 117/119 (98.3%) LPA-susceptible and 94/100 (94%) resistant isolates, with 98.3% specificity and 94% sensitivity. Two isolates that were susceptible on LPA but resistant on HRMA showed silent mutations at 539 and 541 codons on sequencing, while 6 isolates that were susceptible on HRMA but resistant on LPA showed D516V (n = 4) and H526C/D (n = 2) mutations. Four isolates (3.9%) that were resistant on MGIT were susceptible on all three genotypic methods, which could be due to mutations outside the RRDR or efflux pumps. CONCLUSION HRMA shows good potential as a rapid screening tool for the detection of drug resistance.

Abstract
Haptoglobin (Hp) protein has high affinity for hemoglobin (Hb) binding during intravascular hemolysis and scavenges the hemoglobin induced free radicals. Earlier reports indicate about uniqueness of Hp molecule in human and cattle, but in other animals, it is not much studied. In this paper, we characterized buffalo Hp molecule and determined its molecular structure, evolutionary importance, and tissue expression. Comparative analysis and predicted domain structure indicated that the buffalo Hp has an internal duplicated region in α-chain only similar to an alternate Hp2 allele in human. This duplicated part encoded for an extra complement control protein CCP domain. Phylogenetic analysis revealed that buffalo and other ruminants were found to group together separated from all other non-ruminants, including human. The key amino acid residues involved in Hp and Hb as well as Hp and macrophage scavenger receptor, CD163 interactions in buffalo, depicted a significant variation in comparison to other non-ruminant species. Constitutive expression of Hp was also confirmed across all the vital tissues of buffalo, for the first time. Results revealed that buffalo Hp is both structurally and functionally conserved, having internal duplication in α-chain similar to human Hp2 and other ruminant species, which might have evolved separately as a convergent evolutionary process. Furthermore, the presence of extra Hp CCP domain possibly in all ruminants may have an effect during dimerization of molecule in these species.

Abstract
Inverted papilloma (IP) is a rare, benign tumor of the nose and paranasal sinus. However, it is locally aggressive, the recurrence rate is high and malignant transformation is possible. Until now, IP of the hard palate has rarely been reported in the literature. Here, we reported a case with IP of the hard palate, which clinically presented as a carcinomatous growth. The management of IP is complete surgical excision with a close follow-up to detect early recurrence and/or malignant transformation.
