Could have carcinogenic potential? A critical review of current evidence.

There is growing evidence that microbial dysbiosis is intimately related to carcinogenesis across several types of human cancer. is best known for causing acute exudative genitourinary infection in males. can also cause chronic, asymptomatic infection of the female genitourinary tract along with the oropharynx and rectum of both sexes.

Empowering women in sports biomechanics: exploring the impact of mentor circles.

This study evaluated the International Society of Biomechanics in Sports (ISBS) women's mentor circle programme. Forty-eight ISBS women members completed a survey that provided insight into how the circles operated, perceived benefits, and challenges to participation. Most circles met every 6-8 weeks with meetings lasting 1 to 1.

The association of range of motion, lower limb strength, and load during jump landings in professional ballet dancers.

This study aimed to investigate the associations between peak plantarflexion ankle joint moments and vertical ground reaction forces (vGRF) during jump landings, and static ankle dorsiflexion range of motion (ROM), three-dimensional ankle excursions, and lower extremity strength in professional ballet dancers. Twenty-seven professional ballet dancers volunteered to participate (men = 14, women = 13). Participants attended one data collection session to measure dorsiflexion ROM and isometric lower extremity strength.

The impact of pediatric obesity on biomechanical differences across the gait cycle at three walking speeds.

Background: Obesity impacts a child's ability to walk with resulting biomechanical adaptations; however, existing research has not comprehensively compared differences across the gait cycle. We examined differences in lower extremity biomechanics across the gait cycle between children with and without obesity at three walking speeds.

Methods: Full gait cycles of age-matched children with obesity (N = 10; BMI: 25.

Reliability of ankle mechanics during jump landings in turned-out and parallel foot positions in professional ballet dancers.

This study aimed to determine the within- and between-session reliability of ankle mechanics and vertical ground reaction forces (vGRF) during jump landings in turned-out and parallel foot positions in professional ballet dancers. Twenty-four professional ballet dancers (men = 13, women = 11) attended two data collection sessions where they completed five maximal countermovement jumps in each foot position. The ankle joint mechanics and vGRF of the right limb were recorded via a seven-camera motion capture system and one force platform.

A cross-sectional retrospective survey of injury situation and prevalence in female recreational netball players with a focus on knee injuries.

Objectives: To examine situations of injury and injury prevalence in female adult recreational netball players with a focus on knee injuries.

Design: Cross sectional retrospective online survey.

Participants: 193 female adult recreational netball players.

The effect of attentional focus instructions on performance and technique in a complex open skill.

External focus of attention has been shown to promote more automatic motor control, yielding better performance and more efficient technique, than an internal focus. However, most research has used closed-skill tasks in novices. The extent to which the reported pattern of findings generalises to more complex, time-constrained tasks requires further investigation.

The approach towards the ball, rather than the physical characteristics of the kicker, limits accurate rugby place kicking range.

The aim of this study was to understand how a place kicker's range is limited by their approach to the ball and their physical characteristics. Thirty-three kickers performed maximal place kicks and vertical jumps in a laboratory. Whole-body motion and ground reaction forces during the approach phase of the kicks, jump performance and anthropometric measurements of those whose predicted was limited by range (n = 17) rather than accuracy were analysed.

Situations and mechanisms of non-contact knee injury in adult netball: A systematic review.

Objectives: Noncontact knee injuries in netball are a concern due to a range of negative consequences. To reduce the number of injuries, identifying the situation and mechanism of injury is important. This systematic review examined the literature reporting the situation and mechanism of noncontact knee injury in netball.

Microenvironment engineering of osteoblastic bone metastases reveals osteomimicry of patient-derived prostate cancer xenografts.

Representative in vitro models that mimic the native bone tumor microenvironment are warranted to support the development of more successful treatments for bone metastases. Here, we have developed a primary cell 3D model consisting of a human osteoblast-derived tissue-engineered construct (hOTEC) indirectly co-cultured with patient-derived prostate cancer xenografts (PDXs), in order to study molecular interactions in a patient-derived microenvironment context. The engineered biomimetic microenvironment had high mineralization and embedded osteocytes, and supported a high degree of cancer cell osteomimicry at the gene, protein and mineralization levels when co-cultured with prostate cancer PDXs from a lymph node metastasis (LuCaP35) and bone metastasis (BM18) from patients with primary prostate cancer.

A joint kinetic analysis of rugby place kicking technique to understand why kickers achieve different performance outcomes.

We aimed to identify differences in kicking leg and torso mechanics between groups of rugby place kickers who achieve different performance outcomes, and to understand why these features are associated with varying levels of success. Thirty-three experienced place kickers performed maximum effort place kicks, whilst three-dimensional kinematic (240 Hz) and ground reaction force (960 Hz) data were recorded. Kicking leg and torso mechanics were compared between the more successful ('long') kickers and two sub groups of less successful kickers ('short' and 'wide-left') using magnitude-based inferences and statistical parametric mapping.

Kicking foot swing planes and support leg kinematics in rugby place kicking: Differences between accurate and inaccurate kickers.

Place kicking is a complex whole-body movement that contributes 45% of the points scored in international Rugby Union. This study compared the kicking foot swing plane characteristics of accurate and inaccurate kickers, underpinned by differences in their support leg and pelvis kinematics at support foot contact, to identify key technique characteristics. Motion capture data (240 Hz) were collected from 33 experienced kickers, and distinct groups of accurate (n = 18) and inaccurate (n = 8) kickers were identified based on their performance characteristics.

Assessing rugby place kick performance from initial ball flight kinematics: development, validation and application of a new measure.

The appropriate determination of performance outcome is critical when appraising a performer's technique. Previous studies of rugby place kicking technique have typically assessed performance based on ball velocity, but this is not the sole requirement. Therefore, a mathematical model of rugby place kick ball flight was developed to yield a single measure more representative of true performance.

Auxin and ethylene control of growth in epidermal cells of Pisum sativum: A biphasic response to auxin.

The effects of IAA and ethylene have been compared on the development of epidermal cells in intact shoots of etiolated pea plants. In the expanding sub-apical region ethylene has little effect on cell volume over 24 h but between 12 and 24 h rapid increases occur in cell wall thickening, part of which is due to the deposition of longitudinally orientated microfibrils adjacent to the plasmalemma. During this period, there is a rise in the levels of extractable cytoplasmic peroxidase.

Orientation of cell growth in the etiolated pea stem : Effect of ethylene and auxin on cell wall deposition.

Both ethylene and IAA induce swelling in the sub-apical region of etiolated pea plants. The modified cells of these two types of swellings differ both morphologically and in their enzyme composition. In ethylene the cell walls become thickened within 24 h and the level of peroxidase is enhanced; ethylene does not affect cellulase levels.
