The Design of an Intelligent Robotic Wheelchair Supporting People with Special Needs, Including for Their Visual System.

The paper aims to study the applicability and limitations of the solution resulting from a design process for an intelligent system supporting people with special needs who are not physically able to control a wheelchair using classical systems. The intelligent system uses information from smart sensors and offers a control system that replaces the use of a joystick. The necessary movements of the chair in the environment can be determined by an intelligent vision system analyzing the direction of the patient's gaze and point of view, as well as the actions of the head.

Analysis of nonleukemic cellular subcompartments reconstructs clonal evolution of acute myeloid leukemia and identifies therapy-resistant preleukemic clones.

To acquire a better understanding of clonal evolution of acute myeloid leukemia (AML) and to identify the clone(s) responsible for disease recurrence, we have comparatively studied leukemia-specific mutations by whole-exome-sequencing (WES) of both the leukemia and the nonleukemia compartments derived from the bone marrow of AML patients. The T-lymphocytes, B-lymphocytes and the functionally normal hematopoietic stem cells (HSC), that is, CD34 /CD38 /ALDH cells for AML with rare-ALDH blasts (<1.9% ALDH cells) were defined as the nonleukemia compartments.

Transdifferentiations and heterogeneity in the stromal niches of uterine leiomyomas.

Uterine leiomyomas, also known as uterine fibroids (UFs), are benign smooth muscle cells tumors, the most frequent tumors in women. Even though UFs are monoclonal tumors, they contain a heterogeneous and versatile cells population. There are scarce proofs about the processes of transdifferentiation that might occur in UFs, modify the tumor microenvironment and support blood and lymph vessels formation.

Loss of the novel Vcp (valosin containing protein) interactor Washc4 interferes with autophagy-mediated proteostasis in striated muscle and leads to myopathy in vivo.

VCP/p97 (valosin containing protein) is a key regulator of cellular proteostasis. It orchestrates protein turnover and quality control in vivo, processes fundamental for proper cell function. In humans, mutations in VCP lead to severe myo- and neuro-degenerative disorders such as inclusion body myopathy with Paget disease of the bone and frontotemporal dementia (IBMPFD), amyotrophic lateral sclerosis (ALS) or and hereditary spastic paraplegia (HSP).

What podoplanin tells us about cells with telopodes.

Telocytes (TCs) are stromal cells with telopodes, which represent long, thin, moniliform cell processes; however, this morphological feature alone is insufficient to define a cell type. Specific markers of lymphatic endothelial cells (LECs), such as Prox-1, podoplanin (D2-40) or LYVE-1, are not usually tested in TCs. We thus aimed at performing a study in light microscopy to evaluate whether or not LECs could be mistaken for TCs.
