The paper entitled "Two-sample CFA: Solitary and complementary discriminant types of treatment- and control groups" suggests to modify 2-sample and c-sample CFA as follows: While singular patterns of attributes define solitary types, complementary pairs of patterns define complementary types which may be interpreted as poles of a type-defining factor in factor analysis. The new version of 2-sample CFA is illustrated in 2 examples from clinical psychology with patterns of scales and symptoms.

Microbiome composition and turnover in the face of complex lifecycles and bottlenecks: insights through the study of dung beetles.
Appl Environ Microbiol
December 2024
Department of Biology, Indiana University Bloomington, Bloomington, Indiana, USA.
Unlabelled: Microbiome composition and function often change throughout a host's life cycle, reflecting shifts in the ecological niche of the host. The mechanisms that establish these relationships are therefore important dimensions of host ecology and evolution; yet, their nature remains poorly understood. Here, we sought to investigate the microbial communities associated with the complex life cycle of the dung beetle and the relative contributions of host life stage, sex, and environment in determining microbiome assembly.

- This study aimed to evaluate the effectiveness of ultrasound elastography compared to fine-needle aspiration cytology (FNAC) in diagnosing thyroid nodules as benign or malignant.
- The research involved 360 patients with visible thyroid nodules and found that FNAC outperformed ultrasound elastography in terms of sensitivity (92.00%) and specificity (85.33%) for distinguishing benign nodules.
- Ultimately, while ultrasound elastography showed potential with an accuracy of 81.94%, FNAC maintains its status as the gold standard with an accuracy of 85.47%, particularly across different age groups.
Conserved autism-associated genes tune social feeding behavior in C. elegans.

Department of Genetics, Perelman School of Medicine, University of Pennsylvania, Philadelphia, PA, USA.
Article Synopsis
- Animal foraging is a critical behavior seen in both social and solitary species, yet its molecular pathways remain unclear.
- Researchers identified autism-related genes in *C. elegans* that influence social feeding behavior, particularly through chemosensory neurons.
- Specific interaction mechanisms involve the genes NRX-1 and NLG-1 impacting synaptic function, where disruptions lead to a shift from social to solitary feeding behaviors.
Radiation exposure in vesicoureteral reflux diagnostics: a comparative study of direct radionuclide cystography and voiding cystourethrogram.
Nucl Med Commun
January 2025
Department of Pediatric Surgery, Turku University Hospital.
Article Synopsis
- Voiding cystourethrography (VCUG) is widely used to diagnose vesicoureteral reflux (VUR) but has high radiation exposure; direct radionuclide cystography (DRC) was created to address this issue.
- A study involving 156 children assessed the effectiveness of DRC compared to VCUG and found that DRC identified VUR in 35.3% of patients, while VCUG found it in 61.5%.
- Despite DRC being intended as a lower-radiation option, it actually resulted in higher radiation exposure and additional costs, raising questions about its use in screening for VUR.
Opiorphin: an endogenous human peptide with intriguing application in diverse range of pathologies.
Inflammopharmacology
October 2024
Chikara College of Pharmacy, Chitkara University, Rajpura, Punjab, 140401, India.
Article Synopsis
- Mammalian zinc ectopeptidases help turn off nerve and hormone signals on cells.
- A substance called Opiorphin stops these ectopeptidases, making it easier for the body to manage pain and possibly improve mood.
- Opiorphin could be useful for treating various health problems, including pain, mood disorders, and neurodegeneration.
