Lysosomal enzymes and the oxygen burst capability of monocyte-derived macrophages in active drug-resistant tuberculosis patients in relation to cell attachment.

Drug resistance to tuberculosis (TB) has become an obstacle in eliminating tuberculosis. The transmission of drug-resistant TB from patients increases the incidence of primary drug-resistant (DR) TB in individuals who are in close contact. Therefore, it is necessary to incorporate an immunological approach into preventive therapy.

Activities and concentration of alpha-1 antitrypsin and cystatin C in serum from patients with house dust mite asthma.

Background: The proteolytic activities of house dust mite (HDM) allergens are involved in the pathogenesis of asthma by cleaving T-junction protein complexes, increasing the permeability of airway epithelial cells, and enabling the allergens to reach the interstitial tissue. The human body contains natural protease inhibitors such as alpha-1 antitrypsin (AAT) with antiserine protease activity and cystatin C with anticysteine protease activity.

Objective: This study aimed to investigate the behavior of serum AAT and cystatin C levels in patients with HDM-allergic asthma.

High concentration of γ‑H2AX correlates with a marker of apoptotic suppression and PI3K/Akt pathway upregulation in glioblastoma multiforme.

Glioblastoma multiforme (GBM) is a very aggressive type of primary brain tumor in adults with a poor prognosis. DNA double-strand breaks are known to be associated with the development of numerous cancer types due to their ability to generate genomic instabilities. In GBM, the phosphatidylinositol 3-kinase (PI3K)/Akt pathway is a common pathway that can be activated by exogenous and endogenous factors.

Isolated Diaphorase From Bovine Erythrocyte Cannot Reduce Oxidized Cytoglobin (Metcygb).

Background: Cytoglobin (Cygb) is a relatively newly identified globin protein that acts as an oxygen transporter in tissues like hemoglobin (Hb) in erythrocytes and myoglobin (Mb) in muscles. The natural oxidation of the Fe ion in its heme group into metglobin (globin-Fe) made the loses of oxygen binding functions. It is known metHb and metMb can be reduced enzymatically using diaphorase or cyb5r3.

Immunomodulatory effect of in vitro calcitriol in fit and frail elderly.

Introduction: Effect of calcitriol on PBMCs of healthy adults have been well studied but not much is known about its effect on the PBMCs of elderly patients with various degree of frailty syndrome and immune senescence. This study was aimed to assess the effect of in vitro calcitriol immunomodulatory effect on IL-6, IL-10 and IFN-γ in elderly patients who were fit, pre-frail and frail to see which group of patients might get the most benefit of calcitriol.

Methods: This study was an experimental study on the PBMCs of 24 elderly people, of which 8 subjects each were in fit, pre-frail and frail categories based on the Cardiovascular Health Study criteria.

Is the Mitochondrial Function of Keloid Fibroblasts Affected by Cytoglobin?

Background: A keloid is a benign skin tumour characterised by excessive proliferation of fibroblasts, a process that requires a sufficient amount of energy. The energy needs are associated with adequate oxygen (O) flow and well-functioning mitochondria. It is known that cytoglobin (CYGB) has a function in O distribution.

Effects of paternal lymphocyte immunization in women with unexplained infertility.

Objective: Infertility in women could be a result of an excessive production of antisperm antibody (ASA). Paternal lymphocyte immunization (PLI) could decrease the ASA levels, but the mechanism is still unclear. The aim of this study was to analyse the impact of a PLI-induced ASA decline on regulatory T-cell populations and serum interleukin-10 (IL-10) levels in women with unexplained infertility.

Phagocytosis and the antigen-processing abilities of macrophages derived from monocytes in spinal tuberculosis patients.

This study examined the hypothesis that there is an impairment of macrophageal function in spinal TB. We examined macrophageal functions in spinal TB patients. Monocytes were isolated from peripheral blood mononuclear cells (PBMCs) of five spinal TB patients and five healthy persons as control.

Effects of α-tocopherol on hemolysis and oxidative stress markers on red blood cells in β-thalassemia major.

Background: The accumulation of unpaired α-globin chains in patients with β-thalassemia major may clinically create ineffective erythropoiesis, hemolysis, and chronic anemia. Multiple blood transfusions and iron overload cause cellular oxidative damage. However, α-tocopherol, an antioxidant, is a potent scavenger of lipid radicals in the membranes of red blood cells (RBCs) of patients with β-thalassemia major.

Difference of regulatory T cells, IL10, IL6, IFNγ, and IDO levels in female with high ASA and virgin: A research article.

Objective: The maternal immune system requires tolerance for conception to occur. It is not only the balance of Th 1/Th2 that plays a role in pregnancy, but also the regulatory T cells (Tregs) that regulate the important role in pregnancy. One cause of failure in pregnancy is due to immunological factors, including antisperm antibodies (ASA).

High expressions of the cytoglobin and PGC-1α genes during the tissue regeneration of house gecko (Hemidactylus platyurus) tails.

Background: The tissue regeneration process requires high oxygen and energy levels. Cytoglobin (Cygb) is a member of the globin family, which has the ability to bind oxygen, plays a role in dealing with oxidative stress, and carries oxygen into the mitochondria. Energy production for tissue regeneration is associated with mitochondria-especially mitochondrial biogenesis.

Hypoxia and autophagic response of obese adult rat adipocytes which differ in nutritional state during childhood.

The prevalence of obesity in adults is increasing worldwide, which is problematic since obesity is associated with degenerative diseases. Nowadays Indonesia is facing an interesting phenomenon since there are adults who have been obese since childhood and others who conversely were undernourished while young. The biological differences of these two types of obesities are not well understood.

Background: MiR-21 is known to play a role in osteoclast proliferation and differentiation, but the role of serum miR-21 expression in osteoporosis remains unclear. Previous research found that serum miR-21 expression was positively correlated with bone mineral density in postmenopausal osteoporosis patients, but other factors involved in postmenopausal osteoporosis still unknown. This study aimed to determine the role of serum miR-21 expression, concentration of RANKL, OPG, TGF-β1, sclerostin and serum calcium, RANKL/OPG ratio, and physical activity on bone mineral density of spine in hypoestrogenic postmenopausal women with osteoporosis (PMOP) compared with no osteoporosis (PMNOP), with point of interest on the expression of serum miR-21.

Expression and role of HIF-1α and HIF-2α in tissue regeneration: a study of hypoxia in house gecko tail regeneration.

The house gecko () has evolved the ability to autotomize its tail when threatened. The lost part is then regrown via epimorphic regeneration in a process that requires high energy and oxygen levels. Oxygen demand is therefore likely to outstrip supply and this can result in relative hypoxia in the tissues of the regenerating tail.

Role of Hypoxia Inducible Factor-1 Alpha (HIF-1α) in Cytoglobin Expression and Fibroblast Proliferation of Keloids.

Background: Keloids are characterized by an overabundance of collagen deposition due to elevated activity and proliferation of fibroblasts, which lead to hypoxic conditions. Adaptation to these conditions is regulated by the transcription factor hypoxia inducible factor-1α (HIF-1α). Cytoglobin (Cygb), a reactive oxygen species scavenger, is a target gene of HIF-1α.
