The methods of scanning and transmission electron microscopy were used to study erythrocytes from normal subjects and those suffering from anemia of lead poisoning genesis. Erythrocytes from normal subjects were shown to have predominantly convex-concave and biconcave shapes. An insignificant portion of ageing erythrocytes of spherical shape and decreased volume had granular surface and consolidated hemoglobin. Normally, in addition to the above-mentioned cells, erythrocytes with an abnormal relief occur: with perforating openings, crypt-like recesses, tubercles and processes. In anemia, the number of atypical erythrocytes increased many-fold. The process of sequestration and fragmentation of hemoglobin-containing particles is one of the mechanisms of anemia development.

The combination of severe myalgia, progressive weakness, and blood in the urine often leads a neurologist to consider myositis. Accordingly, reddish urine may be linked to urine myoglobinuria brought about by muscle destruction. Nevertheless, in a young patient with normal creatine kinase complaining of immobility, adult-onset Still's disease (AOSD) should be one of the top differentials.

Studying the blood cell morphology of marine mammals provides an opportunity to elucidate the physiological mechanisms of adaptive changes associated with the aquatic habitat that occur at the cellular level, as well as adaptations to changing environmental conditions and under various physiological and pathological processes. The Baikal seal [ (family Phocidae)] is endemic to the freshwater Lake Baikal, but comprehensive hematology data are not available. We studied the morphological features of blood cells of twelve clinically normal, adult Baikal seals ( = 6 males, = 6 females) from two oceanariums under professional care for eight years.

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection has been associated with various hematological disorders. Understanding the pathology of erythrocytes (red blood cells) in coronavirus infection may provide insights into disease severity and progression. To review and analyze the general pathology of erythrocytes in patients infected with SARS-CoV-2, focusing on clinical and laboratory findings across different severity groups.

B-cell lymphoma/leukemia 11A (BCL11A) is a crucial transcriptional regulator, widely recognized for its role in controlling fetal hemoglobin and its potential as a gene therapy target for inherited hemoglobinopathies. Beyond this, recent studies have also highlighted its key role in the maturation and function of immune cells and erythrocytes, mediated through the regulation of various molecules during hematopoietic development. The dysregulation of BCL11A disrupts downstream molecular pathways, contributing to the development of several hematological malignancies, particularly leukemias.

The present study investigated the clinical and hematological effects of chronic lead exposure in the population residing in Shadi Pura, a small industrial zone in Lahore, Pakistan. A cross-sectional analysis of 149 participants recruited through health camps was conducted to explore the hematological manifestations of environmental lead exposure, focusing on various red blood cell (RBC) indices and morphology. Moreover, the study examined the differences in the impact of lead exposure on RBC indices and morphology between men, women, and children.
