Article Synopsis
  • This study explored how specific genetic factors related to HLA-II alleles affect the presence of insulin autoantibodies in children with type 1 diabetes (T1D), involving a sample of 111 T1D children and their families.
  • It found that certain HLA alleles (like DRB1*03:01 and DQB1*02:01) were more common in T1D patients, while other alleles were less frequent, indicating a possible genetic predisposition.
  • The research also suggested that similarities between proteins from gut bacteria and islet cell autoantigens could contribute to the development of T1D, hinting that gut health may be an important factor for those at genetic risk.

Drop foot is a common consequence of Multiple Sclerosis (MS), which may be improved somewhat by an ankle-foot orthosis (AFO). This study aimed to examine the immediate effect of using the recently developed Novel Hybrid Passive Spring Damper AFO (the novel HPSDAFO) on the kinetic and kinematic parameters of patients with MS (PwMS) in the sagittal plane. Twelve PwMS who suffered a unilateral drop foot participated in this study and fitted with the novel HPSDAFO.

Article Synopsis
  • The study analyzed 466 references and 625 data reports to evaluate the concentrations of organic carbon (OC) and elemental carbon (EC) in particulate matter (PM).
  • Traffic areas were found to have the highest concentrations of both OC (17.893 µg/m) and EC (17.893 µg/m), surpassing industrial, urban, and rural areas.
  • The findings suggest a need for monitoring and reduction strategies for PM concentrations, particularly focusing on high-traffic zones to improve air quality.

Background: Mitochondria are known to be involved in mediating the calorigenic effects of thyroid hormones. With an abundance of these hormones, alterations in energy metabolism and cellular respiration take place, leading to the development of cardiac hypertrophy. Vitamin D has recently gained attention due to its involvement in the regulation of mitochondrial function, demonstrating promising potential in preserving the integrity and functionality of the mitochondrial network.

Multiple sclerosis (MS) is an autoimmune neurodegenerative disease that targets myelin, leading to inflammation and neuron death. Monoclonal antibodies (MAb) have long been used to control the progression and exacerbations of this disorder, which may induce secondary autoimmune disease as a rare adverse event. This systematic review aimed to gather data of case reports around this subject and to explain the mechanism behind their occurrence.

Therapeutic Opportunities in Breast Cancer by Targeting Macrophage Migration Inhibitory Factor as a Pleiotropic Cytokine.

Breast Cancer (Auckl)

September 2024

Research Center for Molecular Medicine, Institute of Cancer, Avicenna Health Research Institute (AHRI), Hamadan University of Medical Sciences, Hamadan, Iran.

As a heterogeneous disease, breast cancer (BC) has been characterized by the uncontrolled proliferation of mammary epithelial cells. The tumor microenvironment (TME) also contains inflammatory cells, fibroblasts, the extracellular matrix (ECM), and soluble factors that all promote BC progression. In this sense, the macrophage migration inhibitory factor (MIF), a pleiotropic pro-inflammatory cytokine and an upstream regulator of the immune response, enhances breast tumorigenesis through escalating cancer cell proliferation, survival, angiogenesis, invasion, metastasis, and stemness, which then brings tumorigenic effects by activating key oncogenic signaling pathways and inducing immunosuppression.
