BACKGROUND: Myasthenia gravis (MG) is an autoimmune disorder caused by neuromuscular junction failure characterized by muscle weakness and fatigability. We herein report a case of MG that received intravascular laser irradiation of blood (ILIB) interventions and regained muscle power and better quality of life. To our knowledge, no previous study has investigated the benefits of ILIB treatment on patients with MG. We also evaluated the changes in brain perfusion scan and the MG activities of daily living (MG-ADL) and quantitative MG (QMG) scales...

UNLABELLED: Oxidative stress induced by exercise has been a research field in constant growth, due to its relationship with the processes of fatigue, decreased production of muscle strength, and its ability to cause damage to the cell. In this context, photobiomodulation therapy (PBMT) has emerged as a resource capable of improving performance, while reducing muscle fatigue and muscle damage. To analyze the effects of PBMT about exercise-induced oxidative stress and compare with placebo therapy...

BACKGROUND: Fatigued skin, defined as dehydrated skin with lack of visual facial firmness and dull appearance, can be attributed to intrinsic and extrinsic factors of aging. An antiaging daily serum (AADS) containing a unique sunflower sprout extract (SSE) was formulated to target fatigued and photodamaged skin. AIMS: Utilizing both preclinical and clinical testing models, the efficacy of the AADS was investigated to improve fatigued and photodamaged skin. PATIENTS/ METHOD: Preclinical studies included in vitro analysis of adenosine triphosphate (ATP) production in fatigued dermal fibroblasts, inhibition of ultraviolet radiation A (UVA) induced advanced glycation end products (AGEs) in keratinocytes, and ex vivo gene expression after incubation with the SSE...

BACKGROUND: Tear trough deformity, hyperpigmentation, and skin laxity of the lower eyelid make individuals appear fatigued and elderly. Many patients prefer less invasive, cosmetic correction of the aged lower eyelid. Polydioxanone (PDO)-barbed threads introduced braided fine threads design, which works as a template for attraction of the regenerative factors and for cells' migration and proliferation. The purpose of this study was to estimate the outcomes of simultaneous additional application of braided type PDO threads (N-scaffold) for aged lower eyelids' rejuvenation in patients, who underwent the midface PDO thread lifting...

Hereditary hemorrhagic telangiectasia (HHT), also known as Osler-Weber-Rendu syndrome, is a very rare autosomal dominant genetic disorder that leads to abnormal blood vessel formation in the skin, mucus membranes (called telangiectasia), and organs such as the lung, liver, and brain. It occurs due to a mutation in one of the  ACVRL1 , ENG , and  SMAD4 genes, which code for the formation of blood vessels. The most common symptom is recurring nosebleed (epistaxis; due to rupture of nasal mucosal telangiectasia), which begins in childhood and affects about 90-95% of people with HHT...

Multiple sclerosis is an autoimmune disease of the central nervous system characterized by inflammation and destruction of the myelin sheath. Fatigue is one of the main symptoms of this disease, with a negative impact on quality of life and few treatment options. Photobiomodulation is used for several inflammatory conditions and may be beneficial for the treatment of fatigue in individuals with multiple sclerosis. Conduct a pilot study to analyze the effect of photobiomodulation on fatigue in individuals with relapsing-remitting multiple sclerosis...

The aim of this study was to verify if exposure to the far-IR emitted by fabric (FIR) is able to improve the neuromuscular performance of the knee extensors of resistance-trained males regardless of changes of the temperature. It is a crossover, randomized, double-blind, and placebo-controlled trial. Fourteen resistance-trained males (age: 24.3 ± 4 years; body mass: 82.8 ± 11.3 kg; height: 176.3 ± 4.2 cm) were randomly assigned to one of initial conditions: FIR (n = 7) or placebo (n = 7). After 4 days, the participants were submitted to neuromuscular tests in an isokinetic dynamometer (maximal isometric voluntary contraction (MVC) and fatigue test)...

Benefits of photobiomodulation (PBM) have been known for several decades. More recently, PBM applied in sports offers a special chance to support the modeling of the performance and recovery. Increasingly complex physical activities and fierce competition in the world of sports generate a state of psycho-emotional and physical stress that can induce chronic fatigue syndrome, failure in physical training, predisposition to muscle damage, physical and emotional exhaustion etc., for which PBM could be an excellent solution...

BACKGROUND: Photobiomodulation (PBM) improves motor performance despite doubts whether it occurs immediately or late after a single dose. We evaluated the effect of a cluster PMB (laser + LED) single dose on muscle fatigue recovery in young sedentary adults, both immediately and in the short term (period between 24 and 48 h) after the fatiguing event. METHODS: Randomized clinical trial with 60 volunteers randomized in 5 groups (n = 12 in each): control/(CG); placebo/(SG); PBM in knee extensor/(KE_G); plantar-flexor/(PF_G); knee extensor + plantar-flexor/(KE + FP_G)...
