Objective: To investigate whether bone marrow mesenchymal stem cell (BMSC) treatment could improve the regeneration of endometrium and improve the endometrial receptivity in an experimental model of thin endometrium.
Design: Randomized, control trial, animal research.
Setting: National key laboratory.
Animal(s): Sprague-Dawley rats.
Intervention(s): Bone marrow mesenchymal stem cell transplantation by tail vein IV injection.
Main Outcome Measure(s): Endometrial thickness, the expression of mark proteins for endometrial cell, and endometrial receptivity.
Result(s): The endometrium was significantly thicker and the expression of cytokeratin, vimentin, integrin αγβ3, and leukemia inhibitor factor were significantly stronger compared with the control group. Some proinflammatory cytokines, such as tumor necrosis factor-α (TNF-α) messenger RNA (mRNA) and interleukin-1β mRNA, were significantly down-regulated, and anti-inflammatory cytokines, such as fibroblast growth factor-β (bFGF) mRNA and interleukin-6 mRNA, were significantly up-regulated in the experimental group compared with the control group.
Conclusion(s): The BMSCs have beneficial effect on thin endometrium, and may play a role through migration and immunomodulatory of BMSCs.

Hypercoagulation is central to the pathogenesis of acute and post-acute COVID-19. This prospective observational study explored whether rotational thromboelastometry (ROTEM), a method that unveils coagulation status, predicts outcomes of hospitalized patients with COVID-19 pneumonia. We investigated 62 patients using ROTEM that was conducted at enrollment, clinical deterioration, discharge and follow-up visits 1 and 3 months post-discharge.

(OBVs) represent a diverse group of RNA viruses, encompassing a progressively increasing number of arboviruses that cause disease in both humans and livestock. Yet, studies investigating these viruses remain scarce despite the critical importance of such knowledge for assessing their zoonotic potential. In this study, we conducted an evaluation of the early immune response against the understudied Batai virus (BATV), as well as the influence of reassortment with the Bunyamwera virus (BUNV) on this response.

Vaccine hesitancy among immunocompromised patients is complex and not well understood. This study aimed to determine the rate of COVID-19 vaccine hesitancy among pediatric oncology and bone marrow transplant (BMT) patients and to understand associated factors. : Parents of patients (≤18 years) with cancer or post-BMT completed the Parent Attitudes about Childhood Vaccines Survey.

The treatment of articular cartilage damage has always represented a problem of considerable practical interest for orthopedics. Over the years, many surgical techniques have been proposed to induce the growth of repairing tissue and limit degeneration. In 1994, the turning point occurred: implanted autologous cells paved the way for a new treatment option based more on regeneration than repair.

Background: Nutritional interventions play a critical role in bone marrow transplant (BMT) patients. This review evaluates the effectiveness of nutritional strategies in mitigating post-transplant malnutrition and improving clinical outcomes.
Methods: A systematic review was conducted using PubMed, CINAHL, Cochrane Library, and Embase.
