Uncontrolled activation of the innate immune system promotes deterioration neurons in different neurodegenerative diseases, including amyotrophic lateral sclerosis (ALS). T-cell vaccination (TCV) was developed by Irun Cohen and coworkers at Weizmann Institute Science (Israel) during late 1970s has been demonstrated to be an effective treatment for human autoimmune diseases a regulator macrophage animal models. We treated seven ALS patients with this cell therapy were able slow or stop...

Abstract The complete blood count (CBC) is one of the most requested tests by physicians. CBC tests, realized in conventional hematological analyzers, are restricted to centralized laboratories due frequent maintenance, large devices, and expensive costs required. On other hand, handheld devices commercially available show high prices not liable calibration or control procedures, which results poor quality compared standard hematology instruments. Hilab system a small-handed platform that...

The complete blood count (CBC) is a highly requested test that generally restricted to centralized laboratories, which are limited by high cost, being maintenance-demanding, and requiring costly equipment. Hilab System (HS) small, handheld hematological platform uses microscopy chromatography techniques, combined with machine learning (ML) artificial intelligence (AI), perform CBC test. This ML AI techniques add higher accuracy reliability the results besides allowing for faster reporting....

Chronic myeloid leukemia (CML) is a well-characterized oncological disease in which virtually all patients possess translocation (9;22) that generates the tyrosine kinase BCR::ABL1 protein. This represents one of milestones molecular oncology terms both diagnostic and prognostic evaluations. The detection transcription required factor for CML diagnosis, its quantification essential assessing treatment options clinical approaches. In context, point mutations on ABL1 gene are also challenge...

Infection caused by the human papillomavirus (HPV) is common among sexually active population worldwide. With 200 known genotypes, 15 of them are considered high-risk oncogenic, with types 16 and 18 being most associated anogenital head/neck cancers. The cell cycle, consisting G1, S, G2, M phases, regulated tumor suppressor genes such as Rb p53, whose dysregulation can result in continuous replication damaged cells. High-risk HPVs related to neoplasias, immune response typically eliminates...
