Test developers typically use alternate test forms to protect the integrity of test scores. Because test forms may differ in difficulty, scores on different test forms are adjusted through a psychometrical procedure called equating. When conducting equating, psychometricians often apply smoothing methods to reduce random error of equating resulting from sampling.

Compared with conventional transdermal drug delivery systems, dissolving microneedles significantly enhance drug bioavailability by penetrating the stratum corneum barrier and achieving intradermal drug delivery. In order to improve the transdermal bioavailability of dexmedetomidine hydrochloride, in this study, a novel microneedle delivery system was developed for dexmedetomidine hydrochloride based on 3D printing combined with micro-molding. By systematically optimizing the microneedle geometrical parameters, array arrangement, and preparation process parameters, we determined the optimal ratio of drug-carrying matrix as 15% PVP (polyvinyl pyrrolidone) K90.

Ovarian cancer (OC) remains one of the most lethal gynecologic malignancies due to its asymptomatic progression, frequent late-stage diagnosis, and high rates of chemoresistance and recurrence. Beyond genetic alterations, recent studies highlight the central role of metabolic reprogramming in driving OC initiation, progression, and therapy resistance. OC cells exhibit dynamic metabolic reprogramming, enabling dynamic shifts between glycolysis and oxidative phosphorylation depending on environmental conditions and treatment pressures.

Traditional lipidomics methods are not well-suited for studying unsaturated lipids containing located C═C bonds in single cells. Here, we proposed a single-cell mass spectrometry (MS) platform assisted by a photochemical derivatization (PCD) method termed isible-light-activated u(bpy)-catalyzed inglet xygen-mediated ydroperoxidation (VRSOH), for the rapid and simultaneous detection of multiple lipid C═C location isomers in living cell membranes at the single-cell level. First, the VRSOH method combined with MS analysis achieved the localization of C═C bonds in mono- and polyunsaturated lipids and cellular lipid extracts.

The development of functional endothelial monolayers on synthetic vascular grafts remains challenging, particularly for small-diameter vessels (<6 mm) prone to thrombosis. Here, we present a pharmacological strategy combining 8-(4-chlorophenylthio) adenosine 3',5'-cyclic monophosphate sodium salt (pCPT-cAMP, a tight junction promoter) with nitric oxide/cGMP pathway agonists 3-morpholinosydnonimine (SIN-1), captopril, and sildenafil) to enhance endothelialization. In human umbilical vein endothelial cells (HUVECs), this four-agent cocktail induced a flat, extended phenotype with a 3-fold increased cell area and 57.

Immunotherapy has emerged as a cornerstone strategy for augmenting therapeutic efficacy in acute myeloid leukemia (AML). The immunosuppressive AML microenvironment, characterized by profound immune dysfunction, critically impairs anti-leukemic immune surveillance. This immunologically hostile niche is principally governed by specialized immunosuppressive cell populations-notably regulatory T cells (Tregs), myeloid-derived suppressor cells (MDSCs), leukemia-associated macrophages (LAMs), and regulatory B cells (Bregs)-which collectively establish an immune-privileged sanctuary for leukemic cells.

Charge-trap transistors are widely used for the simulation of biological synaptic functions. However, the unique structure of silicon-oxide-nitride-oxide-silicon (SONOS) makes it difficult to simulate short-term memory (STM). Based on simulation modeling, this work proposes a cylindrical surrounding double-gate (CSDG) nanowire synaptic transistor with a Si N charge trap layer in direct contact with the channel.

Although epidemiological evidence has established a link between physical exercise and reduced risk and recurrence of multiple cancers, the association between physical exercise and cancer risk varies depending on the cancer site. Therefore, there is an urgent need to explore the molecular mechanisms underlying the antitumor effects of exercise to identify which types of cancers can benefit the most from physical exercise. Recent studies have shown that amino acids and exercise-induced lactate can be used by Carnosine Dipeptidase 2 (CNDP2) to synthesize lactoyl amino acids (Lac-AAs), which are then immediately secreted.

The rational design of hybrid organic-inorganic rotaxanes is crucial for advancing molecular machines and functional nanomaterials, yet the integration of metal-oxo clusters into interlocked systems remains challenging. Herein, we present a precision synthesis strategy for hybrid rotaxanes combining γ-cyclodextrin (γ-CD) hosts with Anderson-type polyoxometalate (POM)-based guests. This approach utilizes covalent POM modification coupled with strategically anchored organic functionalities to control supramolecular assembly, enabling the construction of -[2]-, [3]-, and [4]rotaxanes with controlled structural variations.

Thermo-sensitive genic male-sterile (TGMS) lines are fertile at lower temperatures but male sterile above a critical sterility-inducing temperature (CSIT), which varies substantially across TGMS lines. Such lines are valuable resources for breeding two-line hybrid rice (Oryza sativa). However, as their utility is restricted by the CSIT, understanding its regulatory mechanisms has crucial breeding-associated implications.
