Androgens induce renal synthesis of urinary lipocalin-family protein, a potential inter-sexual transmitter in viviparous rockfish.

In viviparous black rockfish (Sebastes schlegelii), the kidney of reproductive-phase males actively produces lipocalin-type prostaglandin D synthase homolog (LPGDSh) protein, which is presumably involved in intersexual communication when emitted in the urine. The present study was undertaken to discover whether androgens and their nuclear receptors (Ars) are engaged in regulation of renal LPGDSh protein synthesis in black rockfish. Quantitative real-time polymerase chain reaction, in conjunction with immunohistochemistry and highly sensitive enzyme-linked immunosorbent assay, revealed that intra-abdominal administration of a synthetic androgen, 17α-methyltestosterone (MT), to juvenile black rockfish induced their renal expression of LPGDSh transcript and protein.

Positive association of large alcohol intake per occasion with vision-threatening severe diabetic retinopathy or diabetic macular edema in Japanese men with type 2 diabetes.

Objective: Differing from the overall consumption of alcohol, whether consuming large quantities of alcohol per drinking occasion is associated with higher risk of developing severe diabetic retinopathy remains unknown.

Methods: We examined whether the quantity per drinking occasion (QPO), including a large QPO, and the combinations of the frequency of alcohol consumption (FAC) and QPO were associated with higher risk of developing severe diabetic retinopathy or diabetic macular edema (DME) using adjusted Cox models. Severe diabetic retinopathy or DME was designated as a vision-threatening treatment-required diabetic eye disease (TRDED).

Construction of carbon dot-embedded fluorescent hydrogels based on oxidized gum arabic-gelatin Schiff base for Cr(VI) detection applications.

In this study, a novel nitrogen-doped carbon quantum dot/oxidized gum arabic-gelatin-based fluorescent probe (NAH) was prepared using gelatin (GL) and gum arabic (AG) biomolecules. The primary network structure of this hydrogel consisted of polyacrylamide (PAM), while a secondary network structure was constructed between oxidized gum arabic and gelatin through the reaction of the Schiff base, which significantly enhanced the mechanical properties, the stress and strain of NAH reached 266.47 KPa and 2175.

Proton Beam Therapy for Pancreatic Tumors: A Consensus Statement from the Particle Therapy Cooperative Group Gastrointestinal Subcommittee.

Boosted antibiotic degradation using magnetite nanoparticles doped ultrafine activated charcoal powder to activate HO: Insights into mechanisms and competitive kinetics.

The treatment of antibiotic wastewater often faces the challenge of simultaneously and effectively degrading multiple components under complex conditions. To address this challenge, magnetite nanoparticles doped ultrafine activated charcoal powder (MNPs/UACP), which effectively catalyzed the decomposition of HO into •OH and HO•, was prepared using chemical co-precipitation. Under optimum conditions (i.

YY2-CYP51A1 signaling suppresses hepatocellular carcinoma progression by restraining de novo cholesterol biosynthesis.

Lipid accumulation is a frequently observed characteristic of cancer. Lipid accumulation is closely related to tumor progression, metastasis, and drug resistance; however, the mechanism underlying lipid metabolic reprogramming in tumor cells is not fully understood. Yin yang 2 (YY2) is a C2H2‑zinc finger transcription factor that exerts tumor-suppressive effects.

Impact of coronary artery tortuosity on outcomes following stenting with newer-generation drug-eluting stents. An analysis of the randomized BIOFLOW trials.

Introduction And Objectives: Patients undergoing percutaneous coronary intervention in vessels with moderate-to-severe tortuosity are at higher risk of adverse outcomes, but data are scarce in the era of newer-generation stents. We compared outcomes following percutaneous coronary intervention in vessels with moderate-to-severe tortuosity using a bioresorbable-polymer sirolimus-eluting stent (BP-SES) vs a durable-polymer everolimus-eluting stent.

Methods: A total of 2350 patients from the BIOFLOW II, IV, and V randomized trials were stratified into 2 groups based on target-vessel tortuosity: none-to-mild and moderate-to-severe.

Tunicate-specific protein Epi-1 is essential for conferring hydrophilicity to the larval tunic in the ascidian Ciona.

Animals must avoid adhesion to objects in the environment to maintain their mobility and independence. The marine invertebrate chordate ascidians are characterized by an acellular matrix tunic enveloping their entire body for protection and swimming. The tunic of ascidian larvae consists of a surface cuticle layer and inner matrix layer.

Enhanced expression of Cyp17a1 and production of DHEA-S in the liver of late-pregnant rats.

Cytochrome P450 17A1 (CYP17A1) catalyzes two enzymatic reactions in the biosynthesis of dehydroepiandrosterone (DHEA) from pregnenolone. In pregnant humans, the adrenal gland is responsible for DHEA biosynthesis, which is then sulfated by SULT2A1 and released into the bloodstream. This sulfated DHEA is subsequently taken up by the placenta and deconjugated to serve as a precursor for estrogen biosynthesis.

Lecanemab-Associated Amyloid-β Protofibril in Cerebrospinal Fluid Correlates with Biomarkers of Neurodegeneration in Alzheimer's Disease.

Objective: The Clarity AD phase III trial showed that lecanemab reduced amyloid markers in early Alzheimer's disease (AD) and resulted in less decline on measures of cognition and function than placebo. Herein, we aimed to characterize amyloid-β (Aβ) protofibril (PF) captured by lecanemab in human cerebrospinal fluid (CSF) from living participants with different stages in AD, which enable an enhanced understanding of the dynamic changes of lecanemab-associated Aβ-PF (Lec-PF) in vivo.

Methods: We newly developed a unique and highly sensitive immunoassay method using lecanemab that selectively captures Lec-PF.

Treatment Outcomes of Canine Orbital Meningiomas in Seven Cases.

Although intracranial and spinal cord meningioma prognoses have been reported, few studies have evaluated the outcomes and prognoses of orbital and optic nerve meningiomas in dogs. We aimed to evaluate the outcomes of canine orbital meningiomas. The seven dogs included were cytologically or histopathologically diagnosed with meningiomas.

Long-Term Survival of Primary Intracranial Histiocytic Sarcoma Through Surgical Resection and Low-Dose CCNU.

Skeletal muscle oxidative capacity related to intramyocellular lipid in young but not in older individuals.

Skeletal muscles contain lipids inside and outside cells, namely intramyocellular lipids (IMCL) and extramyocellular lipids (EMCL), respectively; lipids have also been found to be interspersed between these muscles as adipose tissue, namely intermuscular adipose tissue (IMAT). Metabolized IMCL has been recognized as an important substrate for energy production and their metabolism is determined by the muscle oxidative capacity. Therefore, it has been speculated that muscle oxidative capacity is related to muscle lipid content.
