Muscle stiffness, muscle elasticity and explosive strength are the main components of athletes' performance and they show a sex-based as well as ethnicity variation. Muscle stiffness is thought to be one of the risk factors associated with sports injuries and is less common in females than in males. These observations may be explained by circulating levels of sex hormones and their specific receptors. It has been shown that higher levels of estrogen are associated with lower muscle stiffness responsible for suppression of collagen synthesis. It is thought that these properties, at least in part, depend on genetic factors. Particularly, the gene encoding estrogen receptor 1 (ESR1) is one of the candidates that may be associated with muscle stiffness. Muscle elasticity increases with aging and there is evidence suggesting that titin (encoded by the TTN gene), a protein that is expressed in cardiac and skeletal muscles, is one of the factors responsible for elastic properties of the muscles. Mutations in the TTN gene result in some types of muscular dystrophy or cardiomyopathy. In this context, TTN may be regarded as a promising candidate for studying the elastic properties of muscles in athletes. The physiological background of explosive strength depends not only on the muscle architecture and muscle fiber composition, but also on the central nervous system and functionality of neuromuscular units. These properties are, at least partly, genetically determined. In this context, the ACTN3 gene code for α-actinin 3 has been widely researched.Chronic lymphocytic leukemia (CLL) is a B-cell malignancy characterized by a wide range of tumor-induced alterations, which affect both the innate and adaptive arms of the immune response, and accumulate during disease progression. In recent years, the development of targeted therapies, such as the B-cell receptor signaling inhibitors and the Bcl-2 protein inhibitor venetoclax, has dramatically changed the treatment landscape of CLL. Despite their remarkable anti-tumor activity, targeted agents have some limitations, which include the development of drug resistance mechanisms and the inferior efficacy observed in high-risk patients. Therefore, additional treatments are necessary to obtain deeper responses and overcome drug resistance. Allogeneic hematopoietic stem cell transplantation (HSCT), which exploits immune-mediated graft-versus-leukemia effect to eradicate tumor cells, currently represents the only potentially curative therapeutic option for CLL patients. However, due to its potential toxicities, HSCTd tumor progression. find more From the therapeutic standpoint, we will go through the evolution of immune-based therapeutic approaches over time, including i) agents with broad immunomodulatory effects, such as immunomodulatory drugs, ii) currently approved and next-generation monoclonal antibodies, and iii) immunotherapeutic strategies aiming at activating or administering immune effector cells specifically targeting leukemic cells (e.g. bi-or tri-specific antibodies, tumor vaccines, chimeric antigen receptor T cells, and checkpoint inhibitors).This study explored the relations between Latino gender role attitudes (traditional machismo attitudes and caballerismo attitudes) and sexual behaviors among 242 Mexican American early adolescent boys in the southwest United States. Specifically, a multiple mediator model estimated the association between gender role attitudes and sexual activity through a mediational pathway connecting substance use, sexual motives, and peer influence. Results from analyzing this structural equation model indicated that traditional machismo attitudes were not associated with sexual behaviors. Caballerismo gender role attitudes, however, were indirectly linked with reduced sexual motives and substance via peer influence. This study underscores the importance of social context, behavior, and psychological motivations in explaining differences in sexual motives and substance use among young Mexican American adolescent boys who hold different kinds of beliefs about their gender.

Although the associations between religion and spirituality and mental health and trauma have been studied extensively across various populations, relatively few studies have focused on the postpartum period. This study aimed to shed light on specific domains of religiosity and spirituality that may be resiliency factors for positive postpartum adjustment defined as low depression and high quality of life in mothers oversampled for childhood trauma histories.

We examined several religion and spirituality variables among 108 women at 6 months postpartum as well as prospective relations from religion and spirituality to postpartum depression and quality of life at 12 and 15 months postpartum.

We found that the personal aspects of self-forgiveness and forgiveness for others were most relevant as resiliency factors predicting lower postpartum depression and better quality of life even when controlling for other risks (trauma and demographics). Surprisingly, no other religion and spirituality domain had asso instead of generally studying religion and spirituality as a common marker for coping.

We try to investigate the association between patterns of imaging findings in patients who had a diagnosis of subchondral fracture around the knee, formerly known as SONK and their clinical outcome.

We retrospectively identified 43 knees of 37 patients (28 males, 15 females) who had diagnosis of subchondral fractures around the knee. The mean age is 56-year-old (range 17-83). Musculoskeletal fellowship trained radiologist evaluated all 43 knee MRI in 1)location of marrow edema 2)peri-osseous edema; 3) subchondral fracture line; 4) subchondral articular surface contour; 5)meniscal tear and extrusion; 6)adjacent soft tissue edema; 7) joint effusion. Independent clinical chart review was performed for clinical outcome with follow up time average of 13.3 months (range 0-88 months). Bad outcome was defined as worsening on imaging, continued complaint with surgical management and knee replacement or another episode of SONK. Chi-square analysis and Student's T tests were conducted to test the statistical significance of association between MR findings and outcomes.
