Sorting out the health effects of alcohol

When it comes to your beverage of choice, alcoholic beverages are unique. For millions, they are a regular part of the dining experience. They’re often an important component of social events, celebrations, and milestones; we toast people, events, and memories with alcohol. They play a key role in many religious traditions. And, of course, the alcoholic beverage industry is a major economic force, responsible for more than $220 billion in sales annually in the US. And all of this is true despite the well-known and well-publicized risks of drinking too much alcohol. The negative effects of alcohol It should be a surprise to no one that drinking too much alcohol can be bad for you — of course, the definition of “too much” can vary. More on that in a moment. Here are some of the more common negative health consequences of excessive alcohol consumption — and good reasons to moderate your intake of alcohol: liver disease, including cirrhosis and life-threatening liver failure requiring a liver transplant a higher risk of high blood pressure, heart failure, and dementia a higher risk of certain cancers, including those of the digestive tract (including colon cancer), breast, and liver a higher risk of injury, especially from drunk driving and falls — homicides and suicides are also often alcohol-related lapses in judgement — For example, people who are drunk may engage in risky sexual behavior or use other drugs a higher risk of depression...

ConclusionsUnlike [18F]FDG, [18F]BODIPY 1 showed prominent accumulation in BAT under both inactive and stimulated status. [18F]BODIPY 1 may serve as a valuable BAT PET agent to possibly assess BAT mitochondria density, thus BAT thermogenic capacity after further evaluation.

ConclusionsHypoxia modulation may play a role in nal-IRI ’s mechanism of action. Nal-IRI demonstrated greater anti-tumor activity in the more aggressive and hypoxic tumor model. Furthermore, hypoxia imaging provided early prediction of treatment response.

AbstractPurposeTo investigate and validate the potential role of a radiomics signature in predicting the side-specific probability of extracapsular extension (ECE) of prostate cancer (PCa).ProceduresThe preoperative magnetic resonance imaging data of 238 prostatic samples from 119 enrolled PCa patients were retrospectively assessed. The samples with were randomized in a two-to-one ratio into training (n = 74) and validation (n = 45) datasets. The radiomics features were derived from T2-weighted images (T2WIs). The optimal radiomics features were identified from the least absolute shrinkage and s...

ConclusionThese data establish that [89Zr]anti-CD11b Ab immunoPET targets CD11b+ cells (TAMCs) with high specificity in a mouse model of GBM, demonstrating the potential for non-invasive quantification of tumor-infiltrating CD11b+ immune cells during disease progression and immunotherapy in patients with GBM.

The absence of alloantibodies is a feature of transplantation tolerance. Although the lack of T cell help has been evoked to explain this absence, herein we provide evidence for B cell–intrinsic tolerance mechanisms. Using a murine model of heart tolerance, we showed that alloreactive B cells were not deleted but rapidly lost their ability to differentiate into germinal center B cells and secrete donor-specific antibodies. We inferred that tolerant alloreactive B cells retained their ability to sense alloantigen because they continued to drive T cell maturation into CXCR5+PD-1+ T follicular helper cells. Unexpectedly...

We reported that, while autophagy was necessary for β cell survival, the highly conserved Sel1L-Hrd1 ERAD protein complex was required for the maintenance of β cell maturation and identity. Using single-cell RNA-Seq, we demonstrated that Sel1L deficiency was not associated with β cell loss, but rather loss of β cell identity. Sel1L-Hrd1 ERAD controlled β cell identity via TGF-β signaling, in part by mediating the degradation of TGF-β receptor 1. Inhibition of TGF-β signaling in Sel1L-deficient β cells augmented the expression of β cell maturation markers and increased the t...

AMPK is a key regulator at the molecular level for maintaining energy metabolism homeostasis. Mammalian AMPK is a heterotrimeric complex, and its catalytic α subunit exists in 2 isoforms: AMPKα1 and AMPKα2. Recent studies suggest a role of AMPKα overactivation in Alzheimer’s disease–associated (AD-associated) synaptic failure. However, whether AD-associated dementia can be improved by targeting AMPK remains unclear, and roles of AMPKα isoforms in AD pathophysiology are not understood. Here, we showed distinct disruption of hippocampal AMPKα isoform expression patterns in post...
