Selenium and Chronic Diseases
Selenium (Se) is an essential micronutrient for mammals, and its deficiency seriously threatens human health. A series of biofortification strategies have been developed to produce Se-enriched foods for combating Se deficiency. Although there have been some inconsistent results, extensive evidence has suggested that Se supplementation is beneficial for preventing and treating several chronic diseases. Understanding the association between Se and chronic diseases is essential for guiding clinical practice, developing effective public health policies, and ultimately counteracting health issues associated with Se deficiency. The current review will discuss the food sources of Se, biofortification strategies, metabolism and biological activities, clinical disorders and dietary reference intakes, as well as the relationship between Se and health outcomes, especially cardiovascular disease, diabetes, chronic inflammation, cancer, and fertility.

Redox Control in ALL
Acute lymphoblastic leukemia (ALL) is a hematological malignancy originating from B- or T-lymphoid progenitor cells. Recent studies have shown that redox dysregulation caused by overproduction of reactive oxygen species (ROS) has an important role in the development and progression of leukemia. The application of pro-oxidant therapy, which targets redox dysregulation, has achieved satisfactory results in alleviating the conditions of and improving the survival rate for patients with ALL. However, drug resistance and side effects are two major challenges that must be addressed in pro-oxidant therapy. Oxidative stress can activate a variety of antioxidant mechanisms to help leukemia cells escape the damage caused by pro-oxidant drugs and develop drug resistance. Hematopoietic stem cells (HSCs) are extremely sensitive to oxidative stress due to their low levels of differentiation, and the use of pro-oxidant drugs inevitably causes damage to HSCs and may even cause severe bone marrow suppression.

Appendage Regeneration in Vertebrates
Appendage regeneration in vertebrates means the ability to regenerate amputated or injured tissues and organs, which is a fascinating property shared by several invertebrates and, interestingly, some vertebrates.

Tannery Wastewater
Las aguas residuales de las curtidurías son producto de un proceso de transformación de materia orgánica a materia no degradable, que requiere la adición de compuestos y aditivos que permitan dicha transformación, generando a su vez residuos altamente contaminantes no solo para la salud humana, sino también para el medio ambiente.

Hematopoietic Stem Cells (HSCs)
Hematopoietic stem cells (HSCs) and their offspring, the hematopoietic progenitor cells (HPCs), are highly sociable. Their capacity to interact with bone marrow niche cells and respond to environmental cytokines orchestrates the generation of the different types of blood and immune cells.

Mitophagy
Mitophagy is a selective autophagic process that eliminates unnecessary and/or damaged mitochondria. Therefore, it is a central hormetic mechanism of mitochondrial quality and quantity control, essential for cellular homeostasis. Its dysregulation has been shown to be a key event in metabolic related diseases and it is the target of emerging therapeutical approaches in this field.

ARHGAP11B
ARHGAP11B is a human-specific gene that likely played a crucial role in human neocortex evolution by inducing hallmarks of cortical expansion. In contrast to its ancestral paralog, ARHGAP11A, ARHGAP11B does not act as a Rho GTPase Activating Protein in the nucleus but is localized in mitochondria and increases glutaminolysis. This increase is a prerequisite for increased basal progenitor proliferation – one essential basis for cortical expansion.

TOM Complex Subunits
Mitochondria rely on the translocase of the outer membrane (TOM) complex for the bulk of mitochondrial protein import. In addition to its role as the major entry point for mitochondrial proteins, the TOM complex serves as an entry pathway for viral proteins. TOM complex subunits also participate in a host of interactions that have been studied extensively for their function in neurodegenerative diseases, cardiovascular diseases, innate immunity, cancer, metabolism, mitophagy and autophagy.

TRPC1 in Modulating Cancer Progression
Calcium ions (Ca2+) play an important role as second messengers in regulating a plethora of physiological and pathological processes, including the progression of cancer. Several selective and non-selective Ca2+-permeable ion channels are implicated in mediating Ca2+ signaling in cancer cells. In this review, we are focusing on TRPC1, a member of the TRP protein superfamily and a potential modulator of store-operated Ca2+ entry (SOCE) pathways. While TRPC1 is ubiquitously expressed in most tissues, its dysregulated activity may contribute to the hallmarks of various types of cancers, including breast cancer, pancreatic cancer, glioblastoma multiforme, lung cancer, hepatic cancer, multiple myeloma, and thyroid cancer.

Histone Genes in Drosophila
The evolution of the GC (guanine cytosine) content at the third codon position of the histone genes (H1, H2A, H2B, H3, H4, H2AvD, H3.3A, H3.3B, and H4r) in 12 or more Drosophila species is reviewed. For explaining the evolution of the GC content at the third codon position of the genes, a model assuming selection with a deleterious effect for adenine/thymine and a size effect is presented. The applicability of the model to whole-genome genes is also discussed.
