Salivary gland tumors bear uncanny characteristics of being different based on their morphological aspects rather than the presence of clear demarcation. This ambiguity in the spectrum from benign to malignant salivary gland neoplasms while categorizing the neoplasm is having inherent pitfalls. The present study was, therefore, designed to characterize benign and malignant salivary gland tumors based on their proliferative indices.

Study samples comprised of 97 cases of histopathologically confirmed benign and malignant salivary gland tumors. The cases were immunohistochemically assessed for MCM3 and Ki-67 expressions and the molecular characterization was performed based on the findings.

The majority of benign and malignant salivary gland tumors were from the parotid gland, (51.2%) and (42.4%), respectively. Overall mean labeling index of MCM3 was higher i.e., (5.60 ± 3.99) in comparison to Ki-67 i.e., (2.82 ± 3.14) with P = 0.05 using paired t-test. Besides, malignant salivary gland neoplasms represented a higher mean score of MCM3 and Ki-67 than benign neoplasms.

The requirement of a novel marker has led to the use of MCM3 which has a characteristic role in the entire spectrum of the cell cycle. The present study highlighted the extrapolation of MCM3 over Ki-67 for diagnosis and for true characterization of biologic behavior of salivary gland pathologies which may, in turn, influence the treatment modality employed for such lesions.

It is often caused by cardiovascular diseases, which may be evident or occult. A vast majority of sudden cardiac deaths (to the extent of 90%) are due to ischemia of the working or conducting myocardial tissues consequent to coronary artery diseases. A heterogeneous group of nonischemic myocardial disorders, most producing structural abnormalities are responsible for the remainder; they predominantly represent various cardiomyopathies. This review, in two parts, covers sudden cardiac death in medicolegal autopsies with an approach to some common and uncommon nonischemic myocardial diseases that have a genetic and/or nongenetic basis.The last two decades have seen considerable progress in the use of digital technology in histopathology. Digital photography of microscopic slides and the use of static images gave way to robotic microscopes. These technologies had their own limitations that precluded their widespread use. Creation of whole slide scanners that can produce digitized whole slide images (WSI) and the "comparable to conventional microscope" experience opened multiple avenues for their utilization not only in specific applications such as expert consults, quality assessment programs, education and archiving, but also for routine day-to-day reporting. Industry pressures driven by consumer requirements have led to great development in image quality, speed of scanning, size of stored files, and capital cost of scanners. User-friendly software and analytical algorithms have further enhanced user experience. Challenges that need to be either accepted or overcome would include capital expense not significantly yielding a return on investment, and management of storage space. This review attempts to take the reader through the evolution of WSI scanners and to share the author's experience with WSI for routine histopathology reporting, education, and external quality assessment along with a review of available literature.Transcription factors (TFs) are life-sustaining and, therefore, the subject of intensive research. By regulating gene expression, TFs control a plethora of developmental and physiological processes, and their abnormal function commonly leads to various developmental defects and diseases in humans. Normal TF function often depends on gene dosage, which can be altered by copy-number variation or loss-of-function mutations. This explains why TF haploinsufficiency (HI) can lead to disease. Since aberrant TF numbers frequently result in pathogenic abnormalities of gene expression, quantitative analyses of TFs are a priority in the field. In vitro single-molecule methodologies have significantly aided the identification of links between TF gene dosage and transcriptional outcomes. Additionally, advances in quantitative microscopy have contributed mechanistic insights into normal and aberrant TF function. Cytarabine However, to understand TF biology, TF-chromatin interactions must be characterised in vivo, in a tissue-specific manner and in the context of both normal and altered TF numbers. Here, we summarise the advanced microscopy methodologies most frequently used to link TF abundance to function and dissect the molecular mechanisms underlying TF HIs. Increased application of advanced single-molecule and super-resolution microscopy modalities will improve our understanding of how TF HIs drive disease.

Falls have implications for the health of older adults. Strength and balance interventions significantly reduce the risk of falls; however, patients seldom perform the dose of exercise that is required based on evidence. Health professionals play an important role in supporting older adults as they perform and progress in their exercises. Teleconferencing could enable health professionals to support patients more frequently, which is important in exercise behavior.

This study aims to examine the overall concept and acceptability of teleconferencing for the delivery of falls rehabilitation with health care professionals and older adults and to examine the usability, acceptability, and feasibility of teleconferencing delivery with health care professionals and patients.

There were 2 stages to the research patient and public involvement workshops and usability and feasibility testing. A total of 2 workshops were conducted, one with 5 health care professionals and the other with 8 older adults from a community strength and balance exercise group.
