The knowledge about mammalian iron metabolism has advanced dramatically over the past decades. Studies of genetics, biochemistry and molecular biology allowed us the identification and characterization of many of the molecules involved in regulation of iron homeostasis. Important progresses were made after the discovery in 2000 of a small peptide – hepsidin – that has been proved to play a central role in orchestration on iron metabolism also providing a link between iron metabolism and inflammation and innate immunity. Hepsidin directly interacts with ferroportin, the only known mammalian iron exporter, which is expressed by enterocytes, macrophages and hepatocytes. The direct hepsidin- ferroportin interaction allows an adaptative response from the body in situations that alter normal iron homeostasis (hypoxia, anemia, iron deficiency, iron overload, and inflammation). In clause the items of information on transport protein of iron - transferrin are stated. Its physiological role and clinical importance is shown. Dynamics of the contents of the hepsidin, transferrin, ferritin in persons with latent deficiency of iron. The conclusion about importance of the given parameter for laboratory diagnostics of iron deficiency condition is made. In the article the items of information about the ferritin - protein - depot of iron in body are given. Its physiological role and clinical importance is displayed. Dynamics of changes of the contents ferritin during treatment of the patients with iron deficiency anemia and persons with latent deficiency of iron is shown. The conclusion about the level of the ferritin in serum of blood is the important dynamic parameter for laboratory diagnostics iron deficiency of condition is made.

A basic concept for the automatic diagnosis of histo-pathological specimen is presented. The algorithm is based on tissue structures of the original organ. Low power magnification was used to inspect the specimens. The form of the given tissue structures, e. g. diameter, distance, shape factor and number of neighbours, is measured. Graph theory is applied by using the center of structures as vertices and the shortest connection of neighbours as edges. The algorithm leads to two independent sets of parameters which can be used for diagnostic procedures. First results with colon tissue show significant differences between normal tissue, benign and malignant growth. Polyps form glands that are twice as wide as normal and carcinomatous tissue. Carcinomas can be separated by the minimal distance of the glands formed. First results of pattern recognition using graph theory are discussed.

Clinical Benefits

AbstractLactoferrin (LF) is an iron-binding globular glycoprotein that is structurally and chemically similar to serum transferrin. Many studies have been done to evaluate the effect of oral LF administration on iron deficiency anemia (IDA) with controversial results. This study was designed to compare the efficacy of LF versus oral ferrous sulfate (OFS) therapy in the treatment of children with IDA. A significant increase in mean hemoglobin and serum iron concentrations was noted in the group that received oral bovine LF (11.06 ± 0.96 and 42.79 ± 6.14, respectively) versus the group that received OFS (10.24 ± 0.57 and 28.94 ± 5.05, respectively, with p < 0.001 for each) after 30 days of the treatment with fewer side effects (9.3 vs. 33.3% with p = 0.043). Oral bovine LF is a more effective and safer alternative in treating iron deficiency and IDA compared with OFS with clinical benefits of fewer side effects and better patient compliance.

We have discussed iron preparations for adults in earlier articles;1 much of the information applies equally to children. Iron is not a ‘tonic’ and should be given only to prevent or correct iron deficiency. Estimation of the haemoglobin and inspection of a blood smear are the minimum investigations necessary before iron is prescribed in therapy. When deficiency is suspected in the absence of hypochromic anaemia, plasma iron and iron-binding capacity should be estimated and/or the bone marrow examined for haemosiderin crystals which disappear when iron stores are depleted.

: The term Mitophagy has been newly concerned in reforming metabolic landscape inside cancerous cells in addition to interface between malignant cells as well as other major constituents of tumor microenvironment. Several profoundly interrelated systems, comprising mitochondrial dynamics and mitophagy, function in mammalian cells as vital mitochondrial regulator process, and their consequence in neoplastic development has newly illuminated clinically. In specific instance of cancer cells, mitochondrialprotected metabolic paths are revamped to meet expanded bioenergetics along with biosynthetic necessities of malignant cells in addition to deal with oxidative stress. It is an exhausting task to foresee the role that mitophagy has on malignant growth cells since it relies upon various elements like cancer variability, malignant growth phase, genetic background and harmony between cell demand and accessibility. As per condition, mitophagy may have a double role as cancer suppressor for example Atg5 (autophagy related 5) or Atg7 (autophagy related 7) or execute promoter like function for instance FUNDC1 (FUN14 domain-containing protein 1), BNIP3 (BCL2/adenovirus E1B 19-kDa-interacting protein 3), PINK1 (PTEN-instigated kinase 1) etc. Tumor suppressive function of Parkin (E3 ubiquitin ligase) is likewise distinguished in mammary gland carcinoma where obstruction of mitophagy impacts tumor progression. In pancreatic cancer cells and in hepatocellular carcinoma hypermethylation of the BNIP3, promoter occurs that prevent HIF-1 (HypoxiaInducible Factor 1) binding besides ensuing initiation of mitophagy. Since the double role mitophagy has in malignant growth relying upon various circumstances and cell varieties, a range of studies have been going on mitophagy and its role in cancer progression and development is opening up a new paradigm with immense clinical importance.

Abstract Ferritin values for 250 selected sera were compared with values for iron, total iron-binding capacity (TIBC), and transferrin saturation, to assess the potential of the ferritin assay for the detection of latent iron deficiency. The specimens were grouped (50 in each group) according to their values for iron and TIBC. In Group 1 (low iron, high TIBC) the saturation and ferritin values both indicated iron deficiency in all but one. In the 100 specimens of Groups 2 (normal iron, high TIBC) and 4 (normal iron, high normal TIBC), the saturation values revealed 16 iron-deficient cases, the ferritin test 55. For Groups 3 (low iron, normal TIBC) and 5 (low iron, low TIBC), the ferritin test revealed fewer cases of iron deficiency than did the saturation values (37 cases vs 51 cases, in the 100 specimens). Evidently the ferritin test detects iron deficiency in many cases for whom the serum iron and TIBC tests are not positively indicative. The correlation of serum ferritin with iron, TIBC, and transferrin saturation in the five groups was good only in the case of specimens for which the TIBC was normal; if it was abnormal the correlation was very poor.

Abstract Because of uncertainty as to the molecular weight of transferrin, a previous comparison [Von der Heul et al., Clin. Chim. Acta 38, 347 (1972)] between transferrin content of serum and total iron-binding capacity cannot be definitive. We found a conversion factor for expressing transferrin as iron-binding capacity by measuring the maximum amount of iron bound by 1 mg of transferrin. We compared the resulting calculated value with values obtained by three other methods for measuring total iron-binding capacity. We agree with the previous observation that the latter, as measured radioisotopically, give higher results than would be judged from the transferrin content but the same as those for two chemical methods. The diffusion rate of transferrin in agar was the same irrespective of the degree of iron saturation. Serum transferrin concentrations were low in patients with anemia resulting from malignancy, chronic disorders, and cirrhosis of the liver, and high or normal in patients with iron deficiency anemia and in pregnant women or women who were taking birth-control pills. Measurement of transferrin concentration can be used to distinguish iron deficiency anemia from anemia resulting from chronic disorders, but offers no advantages over existing methods for estimating total ironbinding capacity.

Urothelial Tumours

Primary clear-cell urothelial carcinoma (CCUC) is an uncommon type of urothelial cancer with only 16 cases reported in published literature. Due to the rarity of the tumour, its clinical and prognostic values have not been clearly understood. We present one such rare clinical diagnosis in a 60-year- old man who underwent radical cystectomy (RC) with ileal conduit for urinary bladder cancer. Histopathology showed features of high-grade CCUC infiltrating the muscularis propria. Immunohistochemistry revealed diffuse immunopositivity of pan cytokeratin (CK), GATA3, P40, CK7 but was immunonegative for CD10 and vimentin. Our patient expired 4 months after diagnosis. CCUC has recently been included in the WHO 2016 classification of urothelial tumours. Most of the patients present with poor prognosis. Accurate diagnosis and recognition of this unusual variant are essential for better patient management and prognosis. Early RC seems to be the preferred way of management.
