Compartmental modeling for blood flow quantification from dynamic O-water PET images of humans: a systematic review.
Ann Nucl Med
January 2025
Turku PET Centre, University of Turku and Turku University Hospital, Turku, Finland.
Dynamic positron emission tomography (PET) can be used to non-invasively estimate the blood flow of different organs via compartmental modeling. Out of different PET tracers, water labeled with the radioactive O isotope of oxygen (half-life of 2.04 min) is freely diffusable, and therefore, very well-suited for blood flow quantification.

Department of Nephrology, The First Affiliated Hospital of Sun Yat-sen University, 58Th, Zhongshan Road II, Guangzhou, 510080, People's Republic of China.
Background: Positive anti-ribonucleoprotein antibodies may characterize a subgroup of patients affected by lupus nephritis with mild kidney damage, but little is known about their clinical features and long-term prognosis.
Methods: Patients were retrospectively selected from the lupus nephritis database ( http://ln.medidata.
Identification of association between mitochondrial dysfunction and sarcopenia using summary-data-based Mendelian randomization and colocalization analyses.
J Gerontol A Biol Sci Med Sci
January 2025
Department of Joint Surgery, HongHui Hospital, Xi'an Jiaotong University, Xi'an, Shaanxi, China.
Background: Mitochondrial dysfunction has been demonstrated to be an important hallmark of sarcopenia, yet its specific mechanism remains obscure. In this study, mitochondrial-related genes were used as instrumental variables to proxy for mitochondrial dysfunction, and summary data for sarcopenia-related traits were used as outcomes to examine their genetic association.
Methods: A total of 1,136 mitochondrial-related genes from the human MitoCarta3.
Estimation of factorial expressions and its improvement through calibration: A replication and extension of Tversky and Kahneman (1973).

Fifty years ago, Tversky and Kahneman (Cognitive Psychology, 5[2], 207-232, 1973) reported that people's speeded estimations of 8 × 7 × 6 × 5 × 4 × 3 × 2 × 1 were notably higher than their estimations for the equivalent expression in the opposite order, 1 × 2 × 3 × 4 × 5 × 6 × 7 × 8 (Median = 2,250 vs. 512, respectively). On top of this order effect, both groups grossly underestimated the correct value (40,320).

Objectives: To evaluate the association between polycystic ovary syndrome (PCOS) and the risk of differentiated and papillary thyroid cancer.
Methods: We included all individuals assigned female at birth and born during 1962-1996 in Denmark. Information on vital status, PCOS- and cancer diagnoses, and covariates were attained from various Danish nationwide registers.
