Article Synopsis
  • - The study investigates how climate variables affect frog communities in urban ecosystems in Brazil, focusing on species richness, abundance, and temporal dynamics over three years.
  • - Researchers used statistical models and various methods to analyze seasonality and biodiversity, finding that species richness remained relatively stable, while species abundance fluctuated more due to factors like humidity and temperature.
  • - The results suggest that frog species composition in peri-urban areas tends to remain consistent over time, even amidst climate variations, which provides insights into species coexistence mechanisms and the effects of urbanization on biodiversity.

The synthesis of a Np(IV) polyoxomolybdate-alkoxide sandwich complex, (TBA)[Np{MoO(OMe)NO}] (TBA = tetrabutylammonium), is reported. This compound represents a rare example of a neptunium polyoxometalate cluster isolated outside of water, allowing for characterization of its electrochemical properties in nonaqueous solvents. Complexation of An(IV) cations fine-tunes the redox properties of the cluster, with the observed four reversible reductive events varying slightly both in potential and peak separation depending on the actinide present.

Introduction: Although recurrent diverticulitis appears to be a chronic relapsing disease from a clinical standpoint, there are no sufficient data about inflammatory markers that allow monitoring recurrent diverticulitis in the quiescent phase. Our hypothesis is that serum inflammatory markers may be increased during clinical quiescent phases of diverticulitis and will drop after elective laparoscopic sigmoidectomy for uncomplicated recurrent diverticulitis. We also believe that a drop in IL-6 levels across surgery could be related to an improved quality of life.

The endoplasmic reticulum (ER) is shaped by abundant membrane curvature-generating proteins that include the REEP family member REEP5. The REEP1 subfamily, consisting of four proteins in mammals (REEP1-4), is less abundant and lack a N-terminal region. Mutations in REEP1 and REEP2 cause Hereditary Spastic Paraplegia, but the function of these four REEP proteins remains enigmatic.

Microphysiological systems (MPS) are designed to recapitulate aspects of tissue/organ physiology in vivo, thereby providing potential value in safety and efficacy assessments of FDA-regulated products and regulatory decision-making. While there have been significant advances in the development, use, and proposals of qualification criteria for human organ MPS, there remains a gap in the development using animal tissues. Animal MPS may be of value in many areas including the study of zoonotic diseases, assessment of the safety and efficacy of animal therapeutics, and possibly reduction of the use of animals in regulatory submissions for animal therapeutics.

Objective: Ionizing radiation generates genomic instability by promoting the accumulation of chromosomal rearrangements. The oncogenic translocation RET/PTC1 is present in more than 70% of radiation-induced thyroid cancers. Both RET and CCDC6, the genes implicated in RET/PTC1, are found within common fragile sites - chromosomal regions prone to DNA breakage during slight replication stress.

Introduction: Chronic thromboembolic pulmonary hypertension (CTEPH) is often diagnosed late in acute pulmonary embolism survivors: more efficient testing to expedite diagnosis may considerably improve patient outcomes. The InShape II algorithm safely rules out CTEPH (failure rate 0.29%) while requiring echocardiography in only 19% of patients but may be improved by adding detailed reading of the computed tomography pulmonary angiography diagnosing the index pulmonary embolism.

Purpose: It was demonstrated that differentiated thyroid cancer (DTC) patients may develop multiple primary tumors (MPT) during follow-up. Many studies showed an association between reduced telomere length and cancer phenotype; in particular, the short telomeres were associated with the development of a primary tumor. However, the role of altered telomere length in MPT development has not yet been demonstrated.

Article Synopsis
  • A study investigated the use of extracorporeal membrane oxygenation (ECMO) with reperfusion strategies for high-risk pulmonary embolism (PE) hospitalizations in the U.S. from 2016 to 2020.
  • ECMO was utilized in 2.3% of high-risk PE cases, revealing that its combination with thrombolysis-based reperfusion significantly lowered in-hospital mortality compared to no reperfusion.
  • The study found that while ECMO alone increased mortality, combining it with thrombolysis was beneficial, especially in cardiac arrest patients, suggesting different effectiveness depending on the type of reperfusion strategy used.
