A novel variant in the ABCA1 gene for Tangier Disease with diffuse histiocytosis of bone marrow.

Tangier disease is an extremely rare autosomal recessive monogenic disorder caused by mutations in the ATP binding cassette transporter A1 gene (ABCA1). It is characterized by severe deficiency or absence of high-density lipoprotein cholesterol (HDL-C) and apolipoprotein A-1 (ApoA1), with highly variable clinical presentations depending on cholesterol accumulation in macrophages across different tissues. We report a case of a 47-year-old man with very low HDL-C and very high triglyceride levels, initially attributed to the patient's metabolic syndrome, alcohol abuse, and splenomegaly.

Safety and immunogenicity of different 17DD yellow fever vaccines in golden-headed tamarins (Leontopithecus chrysomelas): Inhibition of viremia and RNAemia after homologous live-attenuated vaccination.

Yellow fever (YF) is a viral disease that affects both humans and non-human primates (NHPs). Neotropical monkeys are more severely stricken by YF and the impact of the disease can be devastating to the endangered golden-headed lion tamarins (GHLTs, Leontopithecus chrysomelas). Susceptible GHLTs were immunized with the commercial Brazilian YF 17DD live attenuated vaccine or two other experimental non-replicating YF vaccines: a purified whole-virus, b-propiolactone-inactivated vaccine and a plant-derived recombinant subunit vaccine.

Determinants of COVID-19 Vaccine Acceptance and Hesitancy: A Systematic Review.

COVID-19 is an infectious disease whose prevention is significantly aided by vaccination, which reduces both case severity and mortality. Despite the safety and efficacy of vaccines, acceptance is not universal, and understanding of the factors influencing vaccination decisions and hesitancy remains limited. This review aims to identify and analyze studies addressing two key questions: what influences the decision to vaccinate and what factors are associated with vaccine hesitancy.

Predictors of Successful Weight Loss in Extremely Obese Individuals Undergoing Roux-en-Y Gastric Bypass Surgery.

Background: Roux-en-Y gastric bypass (RYGB) is a standard treatment for severe obesity, but some patients do not achieve the expected success in weight loss. The aim of this study was to evaluate possible predictors of weight loss after RYGB.

Methods: Sixty-three patients were included.

Ultrastructural characterization of hippocampal inhibitory synapses under resting and stimulated conditions.

The present study uses electron microscopy to document ultrastructural characteristics of hippocampal GABAergic inhibitory synapses under resting and stimulated conditions in three experimental systems. Synaptic profiles were sampled from stratum pyramidale and radiatum of the CA1 region from (1) perfusion fixed mouse brains, (2) immersion fixed rat organotypic slice cultures, and from (3) rat dissociated hippocampal cultures of mixed cell types. Synapses were stimulated in the brain by a 5 min delay in perfusion fixation to trigger an ischemia-like excitatory condition, and by treating the two culture systems with 90 mM high K for 2-3 min to depolarize the neurons.

Health Literacy and Adherence to Therapy in Type 2 Diabetes: A Cross-Sectional Study in Portugal.

Background: Therapy adherence is a key factor in the control of type 2 diabetes mellitus (T2DM). Optimal self-care requires skills in health literacy (HL).

Objective: This study aims to analyze the relationship between HL and adherence to therapy and to understand the possible influence of other sociodemographic and disease variables.

Aminocarb Exposure Induces Cytotoxicity and Endoplasmic Reticulum Stress-Mediated Apoptosis in Mouse Sustentacular Sertoli Cells: Implications for Male Infertility and Environmental Health.

Exposure to pesticides, poses a significant threat to male fertility by compromising crucial cells involved in spermatogenesis. Aminocarb, is a widely used carbamate insecticide, although its detrimental effects on the male reproductive system, especially on sustentacular Sertoli cells, pivotal for spermatogenesis, remains poorly understood. In this study, we investigated the effects of escalating concentrations of aminocarb on a mouse Sertoli cell line, TM4.

Pelage variation and morphometrics of closely related Callithrix marmoset species and their hybrids.

Background: Hybrids are expected to show greater phenotypic variation than their parental species, yet how hybrid phenotype expression varies with genetic distances in closely-related parental species remains surprisingly understudied. Here, we investigate pelage and morphometric trait variation in anthropogenic hybrids between four species of Brazilian Callithrix marmosets, a relatively recent primate radiation. Marmoset species are distinguishable by pelage phenotype and morphological specializations for eating tree exudates.

RNA binding protein-directed control of leukemic stem cell evolution and function.

Strict control over hematopoietic stem cell decision making is essential for healthy life-long blood production and underpins the origins of hematopoietic diseases. Acute myeloid leukemia (AML) in particular is a devastating hematopoietic malignancy that arises from the clonal evolution of disease-initiating primitive cells which acquire compounding genetic changes over time and culminate in the generation of leukemic stem cells (LSCs). Understanding the molecular underpinnings of these driver cells throughout their development will be instrumental in the interception of leukemia, the enabling of effective treatment of pre-leukemic conditions, as well as the development of strategies to target frank AML disease.
