Fine-needle cytological characteristics of carcinoma breast with medullary or medullary-like features masquerading as dendritic reticulum cell sarcoma: An attempt to explore the reasons for erroneous cytologic interpretation
Dilip K Das, Shahed K Pathan, Zafar A Sheikh, Mrinmay K Mallik, Bency John, Fatma MothafferJournal of Cytology 2020 37(2):99-107 Background: Infiltration of tumors by dendritic reticulum cells (DRC) reflects the host immune defense mechanism. We observed three breast carcinomas cases with dense tumor-infiltrating DRC and lymphocytes in fine-needle aspiration (FNA) smears, leading to cytodiagnosis or differential diagnosis of dendritic reticulum cell sarcoma (DRCS). An attempt was made to find...

Tumor cell representation by an improvised technique of fine-needle aspiration specimen acquisition and cell block preparation: Our experience in lung cancer cases in a peripheral center of eastern India
Anup Kr Boler, Shreosee Roy, Arghya Bandyopadhyay, Abhishek Bandyopadhyay, Mrinal Kanti GhoshJournal of Cytology 2020 37(2):87-92 Background: Being a minimally invasive diagnostic technique, Fine-Needle Aspiration Cytology (FNAC) has become the first-line test and corresponding aspirated material has become the target specimen for diagnosis and ancillary tests in lung carcinoma. Although the role of Cell Blocks (CBs) in diagnosis and in ancillary testing is well recognized in literature, limited...

Milan system for reporting salivary gland cytopathology– An experience from Western Indian Population
Vaishali P Gaikwad, Chanda Anupriya, Leena P NaikJournal of Cytology 2020 37(2):93-98 Introduction: Fine-needle aspiration cytology (FNAC) can be challenging to provide a precise diagnosis in salivary gland cytopathology due to diversity of lesions and cytomorphological convergence between the tumors and within the same tumor of salivary gland. The recently proposed Milan System for Reporting Salivary Gland Cytopathology (MSRSGC) provides a risk stratification-based classification system with...

Abstract Introduction Since 2010, the Office of Population Affairs (formerly the Office of Adolescent Health) has offered funding to support expectant and parenting youth through the Pregnancy Assistance Fund (PAF). PAF grantees typically focus on serving young mothers, so programs serving young fathers are more limited. Methods Based on a purposive...

Participation in Non-professional Sports and Cardiovascular Outcomes Among Adolescents: ABCD Growth Study
Abstract Objectives Sports are an important way to improve health during adolescence. However, it is still unclear whether the association between sports, blood pressure, and metabolic profile could be affected by sex, biological maturation, and trunk fatness. The aim of this study was to analyze the association between sports participation and the cluster of cardiovascular markers among adolescents of both sexes. ...

Streptococcus pseudoporcinus: Case Reports and Review of the Literature
Streptococcus pseudoporcinus is a beta-hemolytic Gram-positive, catalase-negative, nonmotile coccus arranged in short chains, usually found in the female genitourinary tract and differentiated from Streptococcus porcinus in 2006. Only two human infections associated with this organism have been reported to date: one in a patient with a first digit wound infection and another with lower extremity cellulitis. We describe two novel cases of Streptococcus pseudoporcinus causing endocarditis in one and...

A phase I study of the VEGFR kinase inhibitor vatalanib in combination with the mTOR inhibitor, everolimus, in patients with advanced solid tumors
Summary Purpose Combining small-molecule inhibitors of different targets was shown to be synergistic in preclinical studies. Testing this concept in clinical trials is, however, daunting due to challenges in toxicity management and efficacy assessment. This study attempted to evaluate the safety and efficacy of vatalanib plus everolimus in patients with advanced solid tumors and explore the utility of dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) studies as a...

Predicting the Past from Minimal Traces: Episodic Memory and its Distinction from Imagination and Preservation
Abstract The paper develops an account of minimal traces devoid of representational content and exploits an analogy to a predictive processing framework of perception. As perception can be regarded as a prediction of the present on the basis of sparse sensory inputs without any representational content, episodic memory can be conceived of as a “prediction of the past” on the basis of a minimal trace, i.e., an informationally sparse, merely causal link to a previous experience....

Metacognitive Development and Conceptual Change in Children
Abstract There has been little investigation to date of the way metacognition is involved in conceptual change. It has been recognised that analytic metacognition is important to the way older children (c. 8–12 years) acquire more sophisticated scientific and mathematical concepts at school. But there has been barely any examination of the role of metacognition in earlier stages of concept acquisition, at the ages that have been the major focus of the developmental psychology of...

Icelandic DNA jigsaw-puzzle brings new knowledge about Neanderthals
An international team of researchers has put together a new image of Neanderthals based on the genes Neanderthals left in the DNA of modern humans when they had children with them about 50,000 years ago. The researchers found the new information by trawling the genomes of more than 27,000 Icelanders. Among other things, they discovered that Neanderthal children had older mothers and younger fathers than the Homo-Sapien children in Africa did at the time.

DNA may not be life's instruction book -- just a jumbled list of ingredients
The common view of heredity is that all information passed down from one generation to the next is stored in an organism's DNA. But one research suggests this might not be so. In two new papers, he argues DNA is just the ingredient list, not the set of instructions used to build and maintain a living organism. The instructions, he says, are stored in the molecules that regulate a cell's DNA and other functioning systems.
