Degloving intramuscular injuries of the semimembranosus and adductor longus muscles in adolescent soccer players.

Degloving muscle injury was described for the rectus femoris where the inner bipennate component is dissociated from its superficial unipennate component. The semimembranosus muscle displays a distinctive dual morphology, featuring both unipennate and bipennate muscle fibers. Nevertheless, this specific tear pattern has not been previously documented.

Negative effects of the SARS-CoV-2 pandemic: The interlinking of maternal attachment representation, coping strategies, parental behavior, and the child's mental health.

For more than two years, young families have been confronted with a large number of restrictions and following burdens as a result of the SARS-CoV-2 pandemic. In fact, it became evident, that the current circumstances are particularly stressful for child's mental health. With regard to the child's mental health in times of a pandemic, additional factors within the family, such as maternal attachment representations as well as coping strategies and parental behavior, may play an important role.

Maternal Sensitivity Modulates Child's Parasympathetic Mode and Buffers Sympathetic Activity in a Free Play Situation.

Background: Behavioral and physiological (self-)regulation in early life is crucial for the understanding of childhood development and adjustment. The autonomic nervous system (ANS) is a main player in the regulative system and should therefore be modulated by the quality of interactive behavior of the caregiver. We experimentally investigated the ANS response of 18-36-month-old children in response to the quality of maternal behavior during a mother-child-interacting paradigm.

Group-Treatment for Dealing with the Work-Family Conflict for Healthcare Professionals.

Healthcare professionals' exposure to work-family conflict negatively affects the health and well-being of the whole family and organizational outcomes. Specified workplace interventions are lacking. Therefore, the aim of the study was to evaluate the feasibility of a two-day group-treatment specifically designed for the needs of healthcare professionals with family responsibilities concerning participation, satisfaction with the intervention and family- and individual-related outcome variables.

Cluster-randomised trial evaluating a complex intervention to improve mental health and well-being of employees working in hospital - a protocol for the SEEGEN trial.

Background: Health care employees in Germany and worldwide are exposed to a variety of stressors. However, most of the hospitals in Germany lack a systematic workplace health management. Thus, this study aims at the evaluation of the effects of a behavioural as well as organisational (´complex´) intervention on the mental health and well-being of hospital staff.

[German Military Families: A Qualitative Inquiry of Strategies of Coping with the Fathers' Absence].

Military families with experiences of deployment are subject to multiple stressors. In this research an explorative qualitative design was used to identify specific challenges, resources and strategies of coping within the families, focusing on the children's perspective. Results show that the fathers' absence causes vital changes in the family system, which demand specific strategies to deal with the abrupt emotional and social challenges.

Dynamics and Structure of Monolayer Polymer Crystallites on Graphene.

Graphene-based nanostructured systems and van der Waals heterostructures comprise a material class of growing technological and scientific importance. Joining materials with vastly different properties, polymer/graphene heterosystems promise diverse applications in surface and nanotechnology, including photovoltaics or nanotribology. Fundamentally, molecular adsorbates are prototypical systems to study confinement-induced phase transitions exhibiting intricate dynamics, which require a comprehensive understanding of the dynamical and static properties on molecular time and length scales.

Imaging techniques. Ultrafast low-energy electron diffraction in transmission resolves polymer/graphene superstructure dynamics.

Two-dimensional systems such as surfaces and molecular monolayers exhibit a multitude of intriguing phases and complex transitions. Ultrafast structural probing of such systems offers direct time-domain information on internal interactions and couplings to a substrate or bulk support. We have developed ultrafast low-energy electron diffraction and investigate in transmission the structural relaxation in a polymer/graphene bilayer system excited out of equilibrium.

Field-driven photoemission from nanostructures quenches the quiver motion.

Strong-field physics, an extreme limit of light-matter interaction, is expanding into the realm of surfaces and nanostructures from its origin in atomic and molecular science. The attraction of nanostructures lies in two intimately connected features: local intensity enhancement and sub-wavelength confinement of optical fields. Local intensity enhancement facilitates access to the strong-field regime and has already sparked various applications, whereas spatial localization has the potential to generate strong-field dynamics exclusive to nanostructures.

Tip-enhanced strong-field photoemission.

Nonlinear photoelectron emission from metallic nanotips is explored in the strong-field regime. The passage between the multiphoton and the optical field emission regimes is clearly identified. The experimental observations are in agreement with a quantum mechanical strong-field model.

Radiological comparison of instrumented posterior lumbar interbody fusion with one or two closed-box plasmapore coated titanium cages: follow-up study over more than seven years.

Study Design: A retrospective clinical study with a follow-up of more than 7 years was conducted.

Objective: To compare interbody fusion, segmental lordosis and changes in disc and foramen height in patients who had received instrumented posterior lumbar interbody fusion (PLIF) with 1 or 2 closed-box titanium cages.

Summary Of Background Data: PLIF using 2 cages is a popular surgical method for treating degenerative lumbar spinal diseases.
