Objectives: To investigate the predictive value of the quantitative T2-FLAIR mismatch ratio (qT2FM) with fully automated tumor segmentation in adult-type diffuse lower-grade gliomas (LGGs).

Materials And Methods: This retrospective study included 218 consecutive patients (mean age, 47 years ± 15 [SD]; 125 males) diagnosed with adult-type diffuse LGG. The cohort was classified into IDH wild-type (IDHwt), IDH-mutant with 1p/19q-codeletion (IDHmut-Codel), and IDH-mutant without 1p/19q-codeletion (IDHmut-Noncodel) subtypes.

Pancreatic ductal adenocarcinoma is characterized by a three-dimensional (3D) tumor microenvironment devoid of oxygen and nutrients but enriched in extracellular matrix, which acts as a physical and chemical barrier. In 3D, cancer cells reprogram their metabolic pathways in ways that help them survive hostile conditions. However, little is known about the metabolic phenotypes of cancer cells in 3D and the intrinsic cues that modulate them.

P2X7 receptor (P2X7R) augments lipopolysaccharide (LPS)-toll-like receptor 4 (TLR4)-mediated neuroinflammation. These roles of P2X7R in neuroinflammation are relevant to nitrosative stress through nuclear factor-κB (NF-κB)-inducible nitric oxide synthase (iNOS) pathway, while the underlying mechanisms are largely unknown. In the present study, we investigated whether protein disulfide isomerase (PDI) is involved in the integration of TLR4-P2X7R functions in response to LPS in vivo.

Cholesteric liquid crystal elastomer fibres gain considerable attention as promising candidates for mechanochromic smart textiles across various domains, ranging from fashion to healthcare. However, intrinsically high hysteresis of cholesteric liquid crystal elastomer during stress relaxation necessitates a time-lag between successive stimulus detections, thereby constraining the practical use in real-world systems. Here, we develop high-tough and low-hysteresis mechanochromic fibres capable of effectively detecting ultra-fast deformations at practical levels.

Distinguishing between endometrial atypical hyperplasia/endometrial intraepithelial neoplasia (EAH/EIN) and grade 1 endometrial endometrioid carcinoma (EEC) requires the evaluation of gland-to-stromal ratio, presence of stromal invasion, extent of epithelial proliferation and nuclear alterations. In small biopsies, stromal invasion may not always be sampled, so other features become more important. However, assessing of some of these features may be subjective.

Objectives: To propose an effective integration method for CT and carbohydrate antigen (CA) 19-9 responses applicable to patients with all stages of pancreatic ductal adenocarcinoma (PDAC) treated with first-line FOLFIRINOX.

Methods: We retrospectively identified patients with PDAC who underwent first-line FOLFIRINOX treatment at a single tertiary hospital between 2017 and 2020. Those with baseline and 8-week follow-up CT scans were included in the CT response dataset.

The cultivation of genetically modified maize expressing Bt proteins against Lepidopteran pests poses a risk for non-target (NT) Lepidoptera, particularly for species inhabiting agroecosystems and whose larvae are susceptible to Bt toxins expressed in maize pollen. Here, laboratory studies were conducted to determine the adverse effects of larval exposure to Cry1F pollen (event TC1507) on host plants on two butterfly (Pieris napi, Aglais io) and two moth species (Plutella xylostella, Ematurga atomaria). All NT Lepidoptera tested were affected by the Cry1F toxin in the pollen, albeit in different degrees depending on the species and the recorded parameter.

Background: Some patients with non-small-cell lung cancer (NSCLC) benefit from immune checkpoint inhibitors (ICIs) despite programmed death-ligand 1 (PD-L1) expression. To address the mechanism of ICI resistance in PD-L1-positive NSCLC, we investigated the role of tumor-cell-intrinsic function of PD-L1 in interleukin (IL)-6-mediated immunosuppression.

Methods: Cohorts of NSCLC patients treated with ICI and public datasets were analyzed.

Introduction: Despite advancements in asthma management, many patients continue to experience poor disease control, lung function decline, and frequent exacerbations. Clinical remission (CR) has been proposed as a novel treatment target and surrogate marker for long-term outcomes. This study evaluates whether early CR at 1 year after inhaled corticosteroid (ICS) initiation influences lung function decline and exacerbation risk in asthma.

Nanocellulose has garnered attention in energy storage as an environmentally friendly and stable separator for lithium-ion batteries (LIBs). However, cellulose nanofibers (CNF) form a dense network that impedes Li-ion migration and limits electrolyte uptake. To develop an efficient LIB separator, polyethylene glycol (PEG) was incorporated with CNF to promote hydrogen bonding, leading to a stable PEG/CNF composite that enhances ionic conductivity.

Background: Left ventricular hypertrophy (LVH) is a strong predictor of adverse outcomes. Although normalizing LV mass (LVM) to height exponents reduced variability from body size, specific recommendations for height exponents are lacking due to a scarcity of normal cohorts to define appropriate height exponents.

Objectives: The authors aimed to show the diagnostic and prognostic implications of establishing height exponents specific to sex, ethnicity, and imaging modality.

Objective: We present a rare case of trisomy 18 of maternal origin in a pregnancy with omphalocele, craniorachischisis, and ectopia cordis.

Case Report: A 38-year-old woman, G3P1A1, was diagnosed with fetal anencephaly, an extrathoracic heart (ectopic cordis), deformity of spine and a stomach-and-intestine-containing omphalocele by prenatal ultrasound at 12 weeks of gestation. The patient's husband was 39 years old and healthy.

Objective: This study retrospectively investigates whether diminished ovarian reserve (DOR), as measured by serum anti-müllerian hormone (AMH), impacts oocyte quality and IVF/ICSI outcomes in the cleavage embryo or blastocyst stage or not.

Materials And Methods: We retrospectively reviewed 1677 women aged ≤40 years who underwent 1862 IVF/ICSI cycles and divided patients into two groups: low-AMH included the patients with AMH levels <1.2 ng/ml, and normal-AMH included the patients with AMH values ≥1.

Menopause, an aged process due to loss of permanent ovarian function (mainly decreased production of estrogen) without another pathological or physiological cause becomes one of the most health issues in the world. Vasomotor symptoms (VMS) is a hallmark of menopause, occurring in up to 80 % of women experiencing and persisting for over seven years with significant negative impacts on physical, psychological, social, and overall wellbeing. Conventionally, menopause hormone therapy (MHT) is considered the most effective therapeutic opinion for many years based on the fact as "deficiency of estrogen"; however, the ratio of benefits and risk is highly debated and always in concern.
