We present WearMoCap, an open-source library to track the human pose from smartwatch sensor data and leveraging pose predictions for ubiquitous robot control. WearMoCap operates in three modes: 1) a Watch Only mode, which uses a smartwatch only, 2) a novel Upper Arm mode, which utilizes the smartphone strapped onto the upper arm and 3) a Pocket mode, which determines body orientation from a smartphone in any pocket. We evaluate all modes on large-scale datasets consisting of recordings from up to 8 human subjects using a range of consumer-grade devices.

Background: While aerobic exercises have demonstrated efficacy in slowing cognitive decline and improving psychological symptoms associated with cognitive impairments, they may not be feasible due to multiple disabilities. Other gentle exercises with mindful approaches, such as "Yoga-like", have been explored but lack clear evidence.

Aim: To assess the efficacy of a "Yoga-like" intervention on cognitive and psychological features in patients with mild to moderate Alzheimer Disease (AD).

Replacing a hopeless molar with a dental implant is one of the most common treatment modalities in implant dentistry. However, immediate implant post-extraction in the posterior region requires managing the bone gap and ensuring primary closure of the socket. To address this anatomical consideration, several authors have proposed using a custom abutment to seal the socket after immediate implant placement, maintain soft tissue contour, and stabilize the surrounding tissues.

Background And Aims: Neurofibromatosis-Noonan syndrome (NFNS) is an extremely rare genetic entity combining the clinical phenotype of two conditions: neurofibromatosis type 1 syndrome (NF1) and Noonan syndrome (NS). Nevertheless, many inconsistencies reside in our understanding of this condition, mainly its clinical features and genetic background. Through this systematic review, we aim to shed light on the epidemiological features, the broad clinical spectrum, the underlying genetic defects and the associated comorbidities of NFNS.

  • Multiple sclerosis (MS) is a disabling condition affecting the brain and spinal cord, and falls pose a significant health risk for individuals with MS (PwMS).
  • A study conducted at the Military Hospital of Tunis surveyed 30 PwMS to assess the frequency and factors associated with falls, finding that 21 participants had fallen at least once.
  • Results indicated that certain clinical assessments and factors, like MS walking ability and vestibular issues, were significantly linked to the likelihood of falls, underlining the importance of using specific scales to identify individuals at risk.

Chitosan, a naturally occurring biopolymer derived from chitin, has emerged as a highly promising instrument for the production and application of metal nanoparticles. The present review delves into the several functions of chitosan in the development and operation of metal nanoparticles, emphasizing its aptitudes as a green reducing agent, shape-directing agent, size-controlling agent, and stabilizer. Chitosan's special qualities make it easier to manufacture metal nanoparticles and nanocomposites with desired characteristics.

In this paper, we propose a new data-aided (DA) joint angle and delay (JADE) maximum likelihood (ML) estimator. The latter consists of a substantially modified and, hence, significantly improved gray wolf optimization (GWO) technique by fully integrating and embedding within it the powerful importance sampling (IS) concept. This new approach, referred to hereafter as GWOEIS (for "GWO embedding IS"), guarantees global optimality, and offers higher resolution capabilities over orthogonal frequency division multiplex (OFDM) (i.

The experiment was conducted in an Open Top Chamber facility located in the Mediterranean basin to investigate how nitrogen (N) fertilization affects the response of wheat to ozone (O) exposure. The study considered the response of Artur Nick, a modern wheat cultivar commonly used in the area, to three O exposure levels (ambient and elevated ambient, +20 and +40 nL L O), and two N fertilization doses (100 and 200 kg ha). Measurements included leaf gas exchange, leaf chlorophyll content, leaf and grain N content, plant growth and yield parameters.

Introduction: Total joint arthroplasty (TJA) for osteoarthritis is one of several treatment options with benefits and harms that patients value differently. However, the process for determining TJA appropriateness does not sufficiently acknowledge patient perspectives. The aim of this paper is to propose an evidence-informed patient-centred conceptual model for elective TJA appropriateness for hip and knee osteoarthritis.

CD14 is one of the key proteins involved in the activation of the inflammatory response of immune cells. CD14 binds bacterial lipopolysaccharide (LPS) and transfers its molecules to the complex of Toll-like receptor 4 (TLR4) and MD-2 protein, which in turn triggers pro-inflammatory signaling pathways necessary to combat infection. CD14 determines the final shape of the pro-inflammatory reaction of cells to LPS, serving as a transporter of this endotoxin and also as a regulator of TLR4 activity.

Article Synopsis
  • Posterior leukoencephalopathy syndrome (PRES) is a rare neurological condition linked to medications like cyclosporine A, which might complicate the diagnosis when patients also have COVID-19.
  • A 16-year-old patient with nephrotic syndrome developed seizures and fever after starting cyclosporine, prompting concern for COVID-19 related brain inflammation, leading to temporary discontinuation of the drug.
  • After recovering from COVID-19, the patient faced seizures again upon restarting cyclosporine, allowing doctors to correctly diagnose the issue as PRES associated with the medication rather than a COVID-19 complication.

Background: The evidence supporting the effectiveness of combined interventions in Alzheimer's disease (AD) patients remains inconclusive.

Objective: The aim of this study was to evaluate the mid- and long-term effectiveness of physical training, alone or combined with cognitive games, on cognitive performance in patients with moderate AD.

Methods: Seventy-nine AD patients (≈73% females, age of ≈70±1 years) were randomly divided into three groups: aerobic-based training (AT-group,  = 27), aerobic-based training plus cognitive games (ACT-group,  = 25), and a control group engaged in reading (CG,  = 26), two sessions per week.
