Soccer-induced fatigue and performance are different between the sexes. The effect of compression stockings (CS) use on fatigue during the soccer match in females is unknown. Thus, we evaluated the impact of CS use during a female soccer match on match-induced fatigue. Twenty soccer players were randomly allocated to two groups (n = 10 for each group): CS and Control (regular socks), and equally distributed within two teams. At rest (baseline 48-h before the match) and immediately post-match, we assessed agility T-test, standing heel-rise test and YoYo Intermittent Endurance Test level 2 (YoYoIE2) performance...

The cereblon modulating agents (CMs) including lenalidomide, pomalidomide and CC-220 repurpose the Cul4-RBX1-DDB1-CRBN (CRL4CRBN ) E3 ubiquitin ligase complex to induce the degradation of specific neomorphic substrates via polyubiquitination in conjunction with E2 ubiquitin-conjugating enzymes, which have until now remained elusive. Here we show that the ubiquitin-conjugating enzymes UBE2G1 and UBE2D3 cooperatively promote the K48-linked polyubiquitination of CRL4CRBN neomorphic substrates via a sequential ubiquitination mechanism...

Onychomadesis occurs when the proximal nail plate becomes unattached to the underlying structures. When only one or a few nails are involved, the cause is usually physical trauma. A 23-year-old female presented with a 4-year history of recurrent onychomadesis involving her bilateral great toes that occurred during the springtime. While recurrent trauma from winter shoes or athletic activities may be a contributing factor, our patient was convinced that wearing tight-fitting socks during winter nights was the primary pathophysiologic process...

Determining and improving the wellbeing of people is one of the priorities of the OECD countries. Nowadays many sensors allow monitoring different parameters in regard to the wellbeing of people. These sensors can be deployed in smartphones, clothes or accessories like watches. Many studies have been performed on wearable devices that monitor certain aspects of the health of people, especially for specific diseases. In this paper, we propose a non-invasive low-cost and low-energy physical wellbeing monitoring system that provides a wellness score based on the obtained data...

Campylobacteriosis is a leading foodborne zoonosis worldwide, and is frequently associated with handling and consumption of poultry meat. Various studies indicate that Campylobacter causes a substantial human disease burden in low to middle-income countries, but data regarding the organism's epidemiology in countries like Kenya are scarce. In sub-Saharan Africa, 3.8 million deaths of children under-5 years of age are reported annually. Of those, 25% are caused by diarrheal diseases, and Campylobacter is one of the most frequently isolated bacteria from diarrheic children...

We previously identified an expressed sequence tag clone, Der f 22, showing 41% amino acid identity to published Der f 2, and show that both genes are possible paralogues. The objective of this study was to characterize the genomic, proteomic and immunological functions Der f 22 and Der f 2. The full-length sequence of Der f 2 and Der f 22 coded for mature proteins of 129 and 135 amino acids respectively, both containing 6 cysteine residues. Phylogenetic analysis of known group 2 allergens and their homologues from our expressed sequence tag library showed that Der f 22 is a paralogue of Der f 2...

Wearable sensors and systems have become increasingly popular in recent years. Two prominent wearable technologies for human activity monitoring are smart textile systems (STSs) and inertial measurement units (IMUs). Despite ongoing advances in both, the usability aspects of these devices require further investigation, especially to facilitate future use. In this study, 18 participants evaluate the preferred placement and usability of two STSs, along with a comparison to a commercial IMU system. These evaluations are completed after participants engaged in a range of activities (e...

A 46 year-old male presented suffering from refractory erectile dysfunction. The patient had a past history of pelvic chondro-sarcoma. This case was a challenge for us; the surgery performed for excision of the sarcoma has resulted in the elimination of both pubic ramia together with excision of part of both corpora and left hemiscrotum. The procedure included a sling application on one side with a mesh sock wrapped around the rear part of the extendor cylinder. Another sling was applied on the contra lateral side without a mesh sock...

We identified a plasma signature of 11 C14 to C26 ceramides and 1 C16 dihydroceramide predictive of major adverse cardiovascular events in patients with acute myocardial infarction (AMI). Among patients undergoing coronary artery bypass surgery, those with recent AMI, compared with those without recent AMI, showed a significant increase in 5 of the signature's 12 ceramides in plasma but not simultaneously-biopsied aortic tissue. In contrast, a rat AMI model, compared with sham control, showed a significant increase in myocardial concentrations of all 12 ceramides and up-regulation of 3 ceramide-producing enzymes, suggesting ischemic myocardium as a possible source of this ceramide signature...

Alopecia of the lower limbs is a rarely reported entity. Friction due to footwear, socks, and tight clothing is one of the causes of lower limb alopecia. The typical site of involvement and improvement after removal of triggering factor are an important clue to the diagnosis. Alopecia areata remains a close differential, and dermoscopy/trichoscopy can serve as an adjunctive aid in the diagnosis.

Augmentation of cardiac sympathetic tone has been shown to induce ventricular arrhythmias. Acupuncture has been clinically used to treat hypertension, angina pectoris, and atrial arrhythmias. However, the effects of acupuncture on ventricular electrophysiology and autonomic tone remain unknown. We hypothesized that acupuncture attenuates cardiac excitability and corrects the imbalance of autonomic tone during sympathetic hyperactivity. Fourteen Yorkshire pigs were randomized to electroacupuncture (EA, 2 Hz, 0...
