A comparative study of biomechanical assessments in laboratory and field settings for manual material handling tasks using extractor tools and exoskeletons.

To enhance physical capabilities of workers who regularly perform physically demanding tasks involving heavy lifting and awkward postures, various tools and occupational exoskeletons can be used. Most of the studies aiming to explore the efficiency of these tools and exoskeletons have been performed in confined and controlled laboratory spaces, which do not represent the real-world work environment. This study aimed to compare the outcome of biomechanical assessment of using a back support exoskeleton and assistive tools (Lever and Jake) in the procedure of a high demanding manual material handling task versus the results found by performing the same task in a laboratory.

Artificial Intelligence for context-aware surgical guidance in complex robot-assisted oncological procedures: An exploratory feasibility study.

Introduction: Complex oncological procedures pose various surgical challenges including dissection in distinct tissue planes and preservation of vulnerable anatomical structures throughout different surgical phases. In rectal surgery, violation of dissection planes increases the risk of local recurrence and autonomous nerve damage resulting in incontinence and sexual dysfunction. This work explores the feasibility of phase recognition and target structure segmentation in robot-assisted rectal resection (RARR) using machine learning.

Strength fitness and body weight status on markers of cardiometabolic health.

Introduction: Recent evidence suggests that resistance training (RT) may reduce metabolic and cardiovascular disease risk. We investigated whether overweight/class I obese individuals by BMI classification with high strength fitness exhibit cardiovascular/metabolic phenotypes similar to those overweight/obese and untrained or those normal-weight with high strength fitness.

Methods: A total of 90 young males were categorized into three groups: overweight untrained (OU, n = 30, BMI > 27 kg·m⁻²), overweight trained (OT, n = 30, BMI > 27 kg·m⁻², RT ≥ 4 d·wk⁻¹), and normal-weight trained (NT, n = 30, BMI < 25 kg·m⁻², RT ≥ 4 d·wk⁻¹).

Effects of resistance training on central blood pressure in obese young men.

Central blood pressure is a predictor of the risk of cardiovascular disease (CVD), and the effects of resistance training (RT) on central blood pressure are largely unknown. This study explored the effects of high-intensity RT on central blood pressure, indices of arterial stiffness and wave reflection and inflammatory/atherogenic markers in overweight or obese, sedentary young men. Thirty-six participants were randomized to RT (12 weeks of training, 3/wk, n=28) or control groups (C, 12 weeks of no training, n=8) and assessed for changes in central and brachial blood pressures, augmentation index (AIx), carotid-femoral pulse wave velocity (cfPWV), carotid intima-media thickness (cIMT), body composition, lipids and inflammatory/atherogenic markers.

Insomnia complaints in patients evaluated for obstructive sleep apnea.

Obstructive sleep apnea (OSA) and insomnia are among the most common sleep diagnoses encountered in the sleep clinic population, however little is known about potential interactions or associations between the two disorders. This retrospective, cross-sectional study was designed to determine the prevalence of insomnia complaints in patients undergoing evaluation for OSA and to ascertain which clinical and polysomnographic features are associated with insomnia. Of 255 consecutive patients who underwent polysomnography for clinically suspected OSA, 54.

Influenza B pneumonia with Staphylococcus aureus superinfection associated with parvovirus B19 and concomitant agranulocytosis.

An 11-year-old patient with anamnestic fever for 3 days and signs of upper respiratory tract infection underwent fulminant Staphylococcus aureus pneumonia with concomitant agranulocytosis. From autopsia influenza B virus and parvovirus B19 were detected by nucleic acid amplification technique (NAT). Specific IgG but no IgM points to preexisting parvovirus B19 infection.

Agrobacterium T-DNA mutation causes the loss of GUS expression in transgenic tobacco.

A new freezer stock of an Agrobacterium tumefaciens clone of LBA4404/pBI121, designated 8999, was found to contain a mutation in the T-DNA region. GUS activity in Agrobacterium 8999 was reduced to levels in negative controls of LBA4404. Additionally, GUS activity in T1 seedlings from tobacco plants transformed with 8999 was reduced to that of untransformed plants.

Recombinant Treponema pallidum antigens in syphilis serology.

Treponema pallidum, the etiological agent of syphilis, is characterized by a paucity of surface exposed outer membrane proteins and a high content of cytoplasma membrane associated lipoproteins. At all stages of infection intense antibody responses against lipoproteins are detectable. In order to provide antigens for syphilis diagnosis the highly immunogenic lipoproteins TpN17, TpN29-35 (TpD), TpN44.
