Seed development is an important event in plant life cycle that has interested humankind since ages, especially in crops of economic importance. Pigeonpea is an important grain legume of the semi-arid tropics, used mainly for its protein rich seeds. In order to understand the transcriptional programming during the pod and seed development, RNA-seq data was generated from embryo sac from the day of anthesis (0 DAA), seed and pod wall (5, 10, 20 and 30 DAA) of pigeonpea variety "Asha" (ICPL 87119) using Illumina HiSeq 2500...

Gitelman's syndrome is an autosomal recessive renal tubular disorder characterized by hypomagnesemia, hypokalemia, hypocalciuria, and metabolic alkalosis. Hypocalcemic tetany as a presentation of Gitelman's syndrome has rarely been reported in literature. We report a rare case of Gitelman's syndrome presenting with hypocalcemic tetany along with hypokalemic periodic paralysis. A 17-year-old female was admitted to our hospital with a history of perioral numbness and carpal spasms of five days duration with progressive quadriparesis developing over a period of few hours...

Studies published from centers across India have reported different and contradicting patterns of glomerular disease. In this retrospective study, we report our experience from a Tertiary Care Center in Northwest India. A total of 702 renal biopsies performed between 2008 and 2013 were reviewed of which 80 were excluded from the study because of having insufficient records or if the biopsies were taken from an allograft. The study included 411 males (66.1 %) and 211 females (33.9%) with an age range of 12-70 years (mean 30...

Recently, two clinical trials of novel agents in metastatic ovarian cancer were published: a phase 3 study of nintedanib and a phase 2 study of volasertib. There seemed to be discordance between the results and conclusions in the publication of both these trials. Despite not very optimistic results, the studies concluded optimistically in favor of the new agents under study. Using these examples, we point out the discrepancies and the risks of concluding optimistically based on statistical significance when the actual benefit is minimal...

Esophageal adenocarcinoma is a deadly cancer with increasing incidence in the United States, but mechanisms underlying pathogenesis are still mostly elusive. In addressing this question, we assessed gene fusion landscapes by comprehensive RNA sequencing (RNAseq) of 55 pretreatment esophageal adenocarcinoma and 49 nonmalignant biopsy tissues from patients undergoing endoscopy for Barrett's esophagus. In this cohort, we identified 21 novel candidate esophageal adenocarcinoma-associated fusions occurring in 3...

Precision medicine is interchangeably used with personalized medicine, genomic medicine and individualized medicine. Collectively, these terms refer to at least 5 distinct concepts in the context of AML. 1st, using molecular or omics data (e.g. genomics, epigenomics, transcriptomics, proteomics) to delineate or define subtypes of AML. 2nd, using these data to select the best therapy for someone with an AML subtype, such as a person with a FLT3-mutation. 3rd, using these data to monitor therapy-response such as measurable residual disease [MRD]-testing...

Cut-throats can be of homicidal, suicidal or accidental origin. In cases of death from a cut-throat, distinguishing the cause is one of the important functions in crime investigation. The features that differentiate suicidal and homicidal cut-throat injuries are the presence of hesitation cuts, depth of wound, signs of struggle, edges of the wound, etc. In the case of a suicidal cut-throat, it is not uncommon to find hesitation cuts but in a homicidal cut-throat, it is uncommon. We present a case of a homicidal cut-throat injury but with hesitation cuts and tailing over the neck, unlike the classical description of homicidal cut-throat injury...

Clinical guidelines continue to move away from routine prostate specific antigen screening (PSA), once a widespread medical practice. A curious difference exists between early prostate cancer and early breast cancer. While randomized trials of therapy in early breast cancer continue to show overall survival benefit, this is not the case in prostate cancer, where prostatectomy was no better than observation in a recent trial, and where early androgen deprivation is no better than late androgen deprivation. Here, I make the case that prostate cancer screening contributes so greatly to over diagnosis that even treatment trials yield null results due to contamination with non-life threatening disease...

The widespread adoption of medical practices without a firm evidence base is common and the current growing enthusiasm for atrial fibrillation screening offers a real-time example of this phenomenon. Although no randomized trials supporting the utility of screening for atrial fibrillation exist, proponents suggest that such screening should be considered. Atrial fibrillation is a common condition that is often asymptomatic. It is also a condition associated with serious morbidity, primarily resulting from stroke...

OBJECTIVE: To determine the strength of the surrogate-survival correlation for cancer drug approvals based on a surrogate. PARTICIPANTS AND METHODS: We performed a retrospective study of the US Food and Drug Administration (FDA) database, with focused searches of MEDLINE and Google Scholar. Among cancer drugs approved based on a surrogate end point, we examined previous publications assessing the strength of the surrogate-survival correlation. Specifically, we identified the percentage of surrogate approvals lacking any formal analysis of the strength of the surrogate-survival correlation, and when conducted, the strength of such correlations...

The ASCO annual meeting draws a large crowd of physicians, cancer researchers, policy makers, and industry representatives. The crown jewel of the annual events is the Plenary session where impactful, influential and visible abstracts are selected for the largest audience. Plenary topics are frequently paired with concurrent New England Journal or Lancet publications.  Here, we review 9 years of ASCO plenary sessions.  Several themes emerge.  First, many of the topics selected have indeed been practice changing, such as the use of ALK inhibitors for ALK rearranged NSCLC, or checkpoint inhibitors in metastatic melanoma...
