RESUMO

Introduction: Polycystic ovary syndrome (PCOS) is a complex hormonal condition associated with psychological, reproductive, and metabolic features. Low-grade inflammation is a recognised factor causing metabolic and reproductive disorders in PCOS, which is why anti-inflammation approaches in PCOS treatment, especially during the COVID pandemic, are considered. A promising therapeutic option is osteopathic manipulative treatment (OMT), which activates the cholinergic anti-inflammatory pathway and can inhibit proinflammatory cytokines, such as TNF, IL-1ß, and TNF-ß. In our paper we analysed the influence of OMT in women with PCOS. Material and methods: Seventy-three patients, aged 29-46 years, with a history of reproductive failure, who underwent a physiotherapeutic treatment were evaluated. Six months after the end of a physiotherapy session, a follow-up questionnaire was performed. Results: The results show that most women (83.6%) were satisfied with the therapeutic process, and that the sessions met the patient's expectations. Reducing the level of anxiety related to infertility treatment and pregnancy was declared by 60 (82.2%) women, an improvement in well-being was declared by 72 (97.3%) (p = 0.04), and increasing awareness of the body after physiotherapy sessions was declared by 70 (95.9%) women. Conclusions: The physiotherapeutic sessions improved infertility treatment, enhanced quality of life, and had a positive effect on overall health in PCOS women.

RESUMO

The aim of the study was to determine whether the Functional Movement Screen (FMS) test carried out among young boys practising football training identifies previous injuries. Sixty-five boys aged 12-13 years, who had regularly practised football in an academy for at least 3 years, were recruited and divided into two groups: an injured group (IG), consisting of players who had experienced at least one injury in the past (n + 25, age 12.32 ± 0.48) and a non-injured group (non-IG), a control group, made up of athletes with no injuries to the musculoskeletal system (n = 40, age 12.25 ± 0.49). Seven FMS tests were used to rate the functional fitness level as a part of the FMS tool. Significant differences between the total scores of the FMS tests (p < 0.001, r = 0.54) were documented. Higher scores in the FMS test were observed in the control group (M = 16.58, SD = 2.04) than in the study group (M = 14.20, ± SD = 1.96). The FMS test is an effective diagnostic tool to identify previous injuries among young football players.

RESUMO

The GeniCore Upgraded Field Assisted Sintering Technology U-FAST was applied to the sintering of a commercial Zr-based bulk metallic glass powder AMZ4. The XRD, SEM and DSC analysis of the sintered compacts showed the benefit of the U-FAST method as an enabler for the production of fully amorphous samples with 100% relative density when sintering at 420 °C/480 s (693 K/480 s) and 440 °C/ 60 s (713 K/480 s). The hardness values for fully amorphous samples, over HV1 519, surpass cast materials and 1625 MPa compressive strengths are comparable to commercial cast products. The advantage of the U-FAST technology in this work is attributed to the high heating and cooling rates inherent to ultra-short pulses, which allow to maintain metastable structures and achieve better temperature control during the process. Increasing sintering temperature and time led to the crystallization of the materials. The geometry and material of the dies and punch determine the thermal inertia and pressure distribution inside the compacts, thus affecting the properties of the near net shape NNS compacts made using the U-FAST device.

RESUMO

The nuclear reaction known as proton-boron fusion has been triggered by a subnanosecond laser system focused onto a thick boron nitride target at modest laser intensity (∼10^{16}W/cm^{2}), resulting in a record yield of generated α particles. The estimated value of α particles emitted per laser pulse is around 10^{11}, thus orders of magnitude higher than any other experimental result previously reported. The accelerated α-particle stream shows unique features in terms of kinetic energy (up to 10 MeV), pulse duration (∼10 ns), and peak current (∼2 A) at 1 m from the source, promising potential applications of such neutronless nuclear fusion reactions. We have used a beam-driven fusion scheme to explain the total number of α particles generated in the nuclear reaction. In this model, protons accelerated inside the plasma, moving forward into the bulk of the target, can interact with ^{11}B atoms, thus efficiently triggering fusion reactions. An overview of literature results obtained with different laser parameters, experimental setups, and target compositions is reported and discussed.
