Pathologic Basis of Diseaseby Stanley L. Robbins is really the fourth edition of hisPathology. Appropriate updating and addition enhance the otherwise identical format, sequence, writing, and illustrations. So many medical students have benefited from this source that it may be the best known general book in the field. I recommend it even more now. Like his former texts, this will be enjoyed for its readability. He clearly lays out a great deal of information. When he includes minutiae, the reasons are clear and one feels that all the material is pertinent. Robbins keeps the whole field in perspective—that is, he does not dwell so long or so heavily on pathologic anatomy or pathogenesis as to tempt the reader to overlook clinical presentation or prognosis. A great strength of the subject of pathology is that it bonds strongly with many other medical sciences and specialties and thus occupies the

Pathologic Basis of Disease

Natural killer cells are the predominant innate lymphocyte subsets that mediate anti-tumor and anti-viral responses, and therefore possess promising clinical utilization. NK cells do not express polymorphic clonotypic receptors and utilize inhibitory receptors (KIR and Ly49) to develop, mature, and recognize ‘self’ from ‘non-self’. The essential roles of common gamma cytokines such as IL-2, IL-7, and IL-15 in the commitment and development of NK cells are well-established. However, the critical functions of proinflammatory cytokines IL-12, IL-18, IL-27, and IL-35 in the transcriptional-priming of NK cells are only starting to emerge. Recent studies have highlighted multiple shared characteristics between NK cells the adaptive immune lymphocytes. NK cells utilize unique signaling pathways that offer exclusive ways to genetically manipulate to improve their effector functions. Here, we summarize the recent advances made in the understanding of how NK cells develop, mature, and their potential translational use in the clinic.

There is currently an unmet need for better biomarkers across the spectrum of renal diseases. In this paper, we revisit the role of Beta 2 microglobulin (β2M) as a biomarker in patients with Chronic Kidney Disease (CKD) and End Stage Renal Disease (ESRD). Prior to reviewing the numerous clinical studies in the area, we describe the basic biology of β2M, focusing in particular on its role in maintaining the serum albumin levels and reclaiming the albumin in tubular fluid through the actions of the neonatal Fc receptor. Disorders of abnormal β2M function arise as a result of altered binding of β2M to its protein cofactors and the clinical manifestations are exemplified by rare human genetic conditions and mice knockouts. We highlight the utility of β2M as a predictor of renal function and clinical outcomes in recent large database studies against predictions made by recently developed whole body population kinetic models. Furthermore, we discuss recent animal data suggesting that contrary to textbook dogma urinary β2M may be marker for glomerular rather than tubular pathology. We review the existing literature about β2M as a biomarker in patients receiving renal replacement therapy, with particular emphasis on large outcomes trials. We note emerging proteomic data suggest that β2M is a promising marker of Chronic Allograft Nephropathy. Finally, we present data about the role of β2M as a biomarker in a number of non-renal diseases. The goal of this comprehensive review is to direct attention to the multi-faceted role of β2M as a biomarker, and its exciting biology in order to propose the next steps thar are required to bring this recently rediscovered biomarkers into the 21st century.

Rediscovering Beta-2 Microglobulin As a Biomarker across the Spectrum of Kidney Diseases.

Breast cancer is the second highest prevalent cancer globally after lung cancer with 2.09 million cases during 2018. Adults about 1.9 billion were overweight and over 650 million out of these were obese during 2016. There is a significant relationship between breast cancer risk and obesity. Premature menopause and premenopausal obesity diminish the risk whereas postmenopausal obesity amplifies the risk, because adipose tissue acts as the major reservoir for estrogen biosynthesis after menopause. Lofty estrogen levels in serum along with enhanced peripheral site production of estrogen have been viewed as major reasons of developing breast cancer in overweight postmenopausal women. This review explains body fat as a peripheral site for estrogen biosynthesis, estrogen exposure affecting body fat distribution, and the mechanism of estrogen production from body fats.

The evolutionary conserved, less-polymorphic, nonclassical major histocompatibility complex (MHC) class I molecules: Qa-1 and its human homologue human leukocyte antigen-E (HLA-E) along with HLA-F, G and H cross-talk with the T-cell receptors and also interact with natural killer T-cells and other lymphocytes. Moreover, these nonclassical MHC molecules are known to interact with CD94/NKG2 heterodimeric receptors to induce immune responses and immune regulations. This dual role of Qa-1/HLA-E in terms of innate and adaptive immunity makes them more interesting. This review highlights the new updates of the mammalian nonclassical MHC-I molecules in terms of their gene organization, evolutionary perspective and their role in immunity.

Aim of this study was to investigate the haematological and serum biochemical parameters of two catfishes Heteropneustes fossilis (Bloch, 1794) and Clarias batrachus (Linnaeus, 1758) of Odisha. In this study, the estimated values were compared between the two species of catfishes as well as with respect to sex. Haematological parameters such as haemoglobin (Hb), total erythrocyte count (TEC), total leucocyte count(TLC), packed cell volume (PCV), mean corpuscular volume (MCV), mean corpuscular haemoglobin (MCH), and mean corpuscular haemoglobin Concentration (MCHC) and the serum biochemical parameters like protein, albumin, globulin, glucose and cholesterol were measured and compared between and within the species as well as with respect to sex using One-Way Analysis of Variance (ANOVA) followed by Turkey’s pair wise comparison tests. All haematological parameters differ significantly (p<0.001) between C. batrachus and H. fossilis except PCV and MCV. Except albumin all biochemical parameters differ significantly between C. batrachus and H. fossilis.

Dental Fluorosis- Revisited

Background: Oral carcinogenesis is a multi-step process. Broadly, oral squamous cell carcinoma (OSCC) can be well-, moderately- or poorly-differentiated, and either keratinizing or non-keratinizing. Most cases are moderately to poorly-differentiated. Precursor lesions (dysplasia) can be categorized into mild, moderate, or severe (carcinoma in situ).In the present study, the pattern of keratin expression in oral squamous cells during carcinogenesis is vividly analysed. Materials and Methods: Samples in the form of scraped and exfoliated cytosmear were collected from the affected sites of the clinically diagnosed 136 oral cancer patients and were immediately fixed in acetoalcohol (1:3). The wet fixed smears were stained by routine Papanicolaou’s staining protocol and Giemsa’s solution. Stained tissues were studied under the microscope. Results: Cytological pleomorphism is a unique feature observed during carcinogenesis. There appears to be a spectrum of degrees of keratinization rather than distinct types, and the degree of keratinization is reflected in the degree of packing and orientation of keratin filaments. It is presumed that alteration in the architectural regularity of the cell membrane is an important aspect of keratinization which leads to cytological pleomorphism during oral carcinogenesis. Conclusion: Pattern of keratinization alongwith cytological pleomorphism in exfoliated epithelial squamous cells has a practical utility in the diagnosis and early detection of oral cancer during carcinogenesis.
