In this paper, a novel system-level mathematical model of the Basal Ganglia (BG) for kinematic planning, is proposed. An arm composed of several segments presents a geometric redundancy. Thus, selecting one trajectory among an infinite number of possible ones requires overcoming redundancy, according to some kinds of optimization. Solving this optimization is assumed to be the function of BG in planning. In the proposed model, first, a mathematical solution of kinematic planning is proposed for movements of a redundant arm in a plane, based on minimizing energy consumption...

Rheumatoid arthritis (RA) is associated with a high risk of osteoporosis and fracture. Interleukin (IL)-6 inhibitors may suppress osteoclast activation. Anticitrullinated protein antibody (ACPA) titers are inversely associated with bone mineral density (BMD). However, the differential effect of ACPA on bone turnover marker (BTM) and BMD changes after IL-6 inhibition remains unclear. This prospective study recruited patients with active RA with inadequate response to methotrexate or biologics. BMD was measured before and after 2-year tocilizumab (TCZ) treatment...

Previous studies have found that Met52®, which contains the entomopathogenic fungus Metarhizium brunneum, is effective in reducing the abundance of Ixodes scapularis, the tick vector for the bacterium causing Lyme disease and for other tick-borne pathogens. Given widespread interest in effective, safe methods for controlling ticks, Met52 has the potential to be used at increasing scales. The non-target impacts of Met52, as applied for tick control, have not yet been assessed. A Before-After-Control-Impact experiment was conducted to assess the effects of Met52 on non-target arthropods in lawn and forest habitats typical of residential yards...

Kinematic gait analysis in the sagittal plane has frequently been used to characterize motor deficits in multiple sclerosis (MS). We describe the application of these techniques to identify gait deficits in a mouse model of MS, known as experimental autoimmune encephalomyelitis (EAE). Paralysis and motor deficits in mice subjected to EAE are typically assessed using a clinical scoring scale. However, this scale yields only ordinal data that provides little information about the precise nature of the motor deficits...

Most infectious diseases that recently emerged in humans originated in animals. Besides close contact between animals and humans, other factors probably contribute to the cross-species transmission of infectious diseases. It is critical to establish effective mechanisms for coordination and collaboration between the animal, human, and environmental health sectors before new threats emerge by bringing the different sectors together to tackle endemic zoonotic diseases of greatest concern. Such multisectoral partnerships should begin by identifying priority zoonotic diseases for national engagement with equal input from the different sectors...

Surfactant protein-D (SP-D) is a collectin, which plays an important role in airway protection and inflammation. The molecule has both pro- and anti-inflammatory capacities depending on its molecular size. Its involvement in joint diseases is largely unknown and the aim of this investigation was to study SP-D occurrence and distribution in the synovial membrane of patients with long-standing rheumatoid arthritis (RA) and osteoarthritis (OA). Six RA patients and six OA patients, who underwent total hip arthroplasty, were included in the study...

Current knowledge of the causes and risk factors of Legg-Calvé-Perthesdisease (LCPD) does not allow effective preventive strategies. The outcome in adulthood is usually good. Hip osteoarthritis rarely develops before 50 years of age. The risk of osteoarthrosis depends chiefly on the final degree of joint incongruence. Age at onset and the lateral pillar classification are the two main outcome predictors and serve to guide the surgical indications based on the studies by Herring's group. Non-operative treatment is not effective...

Osteoarthritis (OA) is a common joint disease characterized by cartilage degradation. Chondroitin sulfate from shark (CS-S) has a good effect on OA in clinical, but due to source limited of CS from shark. Therefore, it is important to find a novel CS source with similar efficacy to CS-S in the treatment of OA. Herein, we reported a therapeutic effect of CS from scophthalmus maximus (CS-SM) for treating OA in rats. The OA model was established. After intervention with CS-SM by intragastric administration. Our results showed that CS-SM could protect articular cartilage in OA, inhibit the degradation of cartilage, decrease the apoptosis of chondrocytes, decline the content of interleukin-1, tumor necrosis factor-α and Prostaglandins E2 in synovial fluid, down-regulate the protein expression of matrix metalloproteinase-1 and up-regulate the protein expression of tissue inhibitor of metalloproteinase-1...

Bioinformatics pipelines are an integral component of next-generation sequencing (NGS). Processing raw sequence data to detect genomic alterations has significant impact on disease management and patient care. Because of the lack of published guidance, there is currently a high degree of variability in how members of the global molecular genetics and pathology community establish and validate bioinformatics pipelines. Improperly developed, validated, and/or monitored pipelines may generate inaccurate results that may have negative consequences for patient care...

Hemophilic arthropathy (HA) is one of the most common and typical manifestation in the course of recurrent bleeding episodes in patients with hemophilia. Clinical and subclinical joint bleeding episodes gradually lead to irreversible changes manifesting themselves as pain, progressing ankylosis, marked limitation of the range of motion, muscle atrophy and osteoporosis commonly concomitant with joint deformity resulting from chronic proliferative synovitis and both cartilage and bone degeneration leading to the final functional impairment of the joint...

After a thorough review of the history and presentation of a child's facial pain, a targeted head and neck examination is critical to the appropriate diagnosis of facial pain and temporomandibular joint disorders. It is critical to distinguish between the structural (trauma, degenerative disease, and tumor) and nonstructural (neurogenic, myogenic, and psychological) causes of pain, which will allow for incorporation of appropriate strategies of medical, psychological, dental, and surgical therapies.

Cells within cartilaginous tissues are mechanosensitive and thus require mechanical loading for regulation of tissue homeostasis and metabolism. Mechanical loading plays critical roles in cell differentiation, proliferation, biosynthesis, and homeostasis. Inflammation is an important event occurring during multiple processes, such as aging, injury, and disease. Inflammation has significant effects on biological processes as well as mechanical function of cells and tissues. These effects are highly dependent on cell/tissue type, timing, and magnitude...

Background: Non-communicable diseases (NCDs) kill 40 million people each year. The management of chronic respiratory NCDs such as chronic obstructive pulmonary disease (COPD) is particularly critical in Italy, where they are widespread and represent a heavy burden on healthcare resources. It is thus important to redefine the role and responsibility of respiratory specialists and their scientific societies, together with that of the whole healthcare system, in order to create a sustainable management of COPD, which could become a model for other chronic respiratory conditions...

Diffuse idiopathic skeletal hyperostosis (DISH) is common spinal condition characterized by increased calcification and ossification of ligaments and entheses, typically in the anterior aspect of the spine. However, extraspinal manifestations of the disease can occur and depending on the degree and location of involvement, may become symptomatic. We present the case of a 63-year-old male with a history of DISH, who failed initial open distal clavicle excision due to the postoperative development of heterotopic bone bridging across the acromioclavicular joint...
