Even seemingly homogeneous on the surface, the oceans display high environmental heterogeneity across space and time. Indeed, different soft barriers structure the marine environment, which offers an appealing opportunity to study various evolutionary processes such as population differentiation and speciation. Here, we focus on Amphiprion clarkii (Actinopterygii; Perciformes), the most widespread of clownfishes that exhibits the highest colour polymorphism.

The short-lived nature and heterogeneity of Natural Killer (NK) cells limit the development of NK cell-based therapies, despite their proven safety and efficacy against cancer. Here, we describe the biological basis, detailed phenotype and function of long-lived anti-tumour human NK cells (CD56CD16), obtained without cell sorting or feeder cells, after priming of peripheral blood cells with Bacillus Calmette-Guérin (BCG). Further, we demonstrate that survival doses of a cytokine combination, excluding IL18, administered just weekly to BCG-primed NK cells avoids innate lymphocyte exhaustion and leads to specific long-term proliferation of innate cells that exert potent cytotoxic function against a broad range of solid tumours, mainly through NKG2D.

Article Synopsis
  • - The study investigates the role of Natural Killer (NK) cells in the immune response to COVID-19, revealing that while NK cells from severely ill patients are more activated, they are actually less effective at mediating antibody-dependent cellular cytotoxicity (ADCC) compared to those from patients with mild cases.
  • - A specific NK cell population lacking the activating receptor NKG2D was found in severe COVID-19 patients, which correlated with high levels of NKG2D ligands in their plasma, suggesting a link to impaired NK cell function.
  • - The findings imply that reduced NK cell function in severe COVID-19 may allow for greater viral replication, challenging the idea that dysfunctional NK cells directly cause severe immune dysreg

Objectives: The microcystic, elongated and fragmented pattern of invasion can be associated with an underestimation of the depth of myometrial invasion by imaging techniques. We aimed to evaluate the influence of microcystic, elongated and fragmented pattern of invasion in the diagnostic performance of transvaginal ultrasound scan and magnetic resonance imaging for the prediction of the depth of myometrial invasion in low-grade endometrioid endometrial carcinomas.

Methods: Prospective and consecutive study including all low-grade (G1-G2) endometrioid endometrial carcinomas diagnosed between October 2013 and July 2018 in a tertiary hospital.

Disinformation and historical revisionism have been acknowledged as tools for foreign interference that belong to the landscape of hybrid threats. Historical revisionism plays an essential role in Russian foreign policy towards the post-Soviet space and is in strong relation with the concepts of Near Abroad and Russkii Mir ('Russian World') and with certain ideas contained in the neo-Eurasianist Movement. This article examines Russian revisionist narratives disseminated in information and influencing campaigns in Europe and against the West.

Bacillus Calmette-Guérin (BCG), the nonpathogenic strain used as tuberculosis vaccine, has been successfully used as treatment for non-muscle invasive bladder cancer for decades, and suggested to potentiate cellular and humoral immune responses. However, the exact mechanism of action is not fully understood. We previously described that BCG mainly activated anti-tumor cytotoxic NK cells with upregulation of CD56 and a CD16 phenotype.

Purpose: To discriminate suspect glaucomatous from control eyes using corneal densitometry based on the statistical modeling of the pixel intensity distribution of Scheimpflug images.

Methods: Twenty-four participants (10 suspect glaucomatous and 14 control eyes) were included in this retrospective study. Corneal biomechanics was assessed with the commercial Scheimpflug camera Corvis ST (Oculus).

Article Synopsis
  • There are still many unanswered questions about the immune response to SARS-CoV-2, especially regarding the role of preexisting T and B cell memory from related coronaviruses in unexposed individuals.
  • Research shows that antibody responses to SARS-CoV-2 are mainly found in individuals who have recovered from COVID-19, while about 30% of pre-pandemic samples exhibited T cell responses that can recognize SARS-CoV-2.
  • Although these pre-pandemic T cells can react to SARS-CoV-2, their responses were weak, suggesting that the ability of these T cells to expand and effectively respond to the virus may be limited, highlighting gaps in our understanding of immunity to SARS-CoV-2.

Article Synopsis
  • Hemoperitoneum from a non-traumatic liver rupture is uncommon, but it can happen in cases of metastatic tumors, like gastrointestinal stromal tumors (GIST).
  • The article discusses a patient who experienced a liver rupture from a GIST metastasis, leading to severe instability that required emergency surgery.
  • During the surgery, doctors found a large lesion on the liver and bleeding due to the rupture of metastatic liver tumors, highlighting a potential serious complication of GISTs.

Purpose: To review the diagnostic and therapeutic procedures of patients diagnosed with Endometrial Stromal Sarcoma (ESS) and Undifferentiated Uterine Sarcoma (USS) at our institution and investigate their clinical outcomes and factors affecting prognosis.

Methods: We retrospectively collected demographic data, preoperative diagnostic methods and therapeutic management of patients treated for ESS and UUS between January 1995 and December 2019 at Vall d'Hebron Barcelona Hospital Campus, Spain. Overall survival and disease-free survival were calculated.

Background: Silicon (Si) is categorized as a -essential element for plants thanks to the benefits on growth, development and metabolism in a hormetic manner. Si uptake is cooperatively mediated by Lsi1 and Lsi2. Nevertheless, Lsi channels have not yet been identified and characterized in pepper (), while genes involved in major physiological processes in pepper are Si-regulated.

Peroxiredoxin 6 (PRDX6) has been associated with tumor progression and cancer metastasis. Its acting on phospholipid hydroperoxides and its phospholipase-A2 activity are unique among the peroxiredoxin family and add complexity to its action mechanisms. As a first step towards the study of PRDX6 involvement in cancer, we have constructed a human hepatocarcinoma HepG2 cell line using the CRISPR/Cas9 technique and have characterized the cellular response to lack of PRDX6.

Tyrosinase starts melanogenesis and determines its course, catalyzing the oxidation by molecular oxygen of tyrosine to dopa, and that of dopa to dopaquinone. Then, nonenzymatic coupling reactions lead to dopachrome, which evolves toward melanin. Recently, it has been reported that d-tyrosine acts as tyrosinase inhibitor and depigmenting agent.

Not only ae cardiac hibernomas rare, ante-mortem diagnosis is poor, due to the clinical and radiological similarity with other intracardiac masses. Furthermore, cardiac hibernomas can be asymptomatic and thus escape detection with imaging studies. We present a case of an 81-year-old woman who died as a result of pulmonary tumor embolism.
