As unexpected adverse events and successful drug repositioning have shown, drug effects are complex and include aspects not recognized by developers. How can we understand these unrecognized drug effects? Drug effects can be numerized by encompassing biological responses to drugs. For instance, the transcriptome data of cultured cells and toxicopathological images of mice treated with a compound represent the effects of the compound in vitro and in vivo, respectively.

Kampo medicine, comprising various conventional crude drug products, poses challenges in identifying adverse event causality. We present a case of severe liver injury following the administration of Saibokuto and attempted to identify the likely causative crude drug inducing liver injury through a systematic literature review. A 29-year-old woman developed severe liver injury approximately two months after Saibokuto administration, necessitating steroid pulse therapy for recovery.

This study aimed to identify novel α-amylase inhibitory peptides from Russian sea cucumbers and elucidate their inhibitory mechanisms. Among the 52 identified sea cucumber peptide (SCP), two peptides with potential α-amylase inhibitory activity, FPSPPLVA (SCP1) and GPPMPPPPLP (SCP2), were selected from the sequences researched. The results showed that both SCP1 and SCP2 exhibited α-amylase inhibitory activity with IC of 0.

Background: Atrial functional mitral regurgitation (AFMR) and heart failure with a preserved ejection fraction (HFpEF) often coexist. However, the clinical impact of HFpEF in patients with AFMR has not been well characterized. This study aimed to determine clinical outcomes and response to mitral valve (MV) intervention or rhythm control therapy in patients with HFpEF and moderate AFMR (HFpEF-AFMR).

Hydrophobicity is associated with drug transport across membranes and is expressed as the partition coefficient log P for neutral drugs and the distribution coefficient log D for acidic and basic drugs. The log P and log D predictions are deductively (or with artificial intelligence) estimated as the sum of the partial contributions of the scaffold and substituents of a single molecule and are used widely and affirmatively. However, their predictions have not always been comprehensively accurate beyond scaffold differences.

Objective: Recent studies have reported the prognostic implications of the discordance between creatinine-based and cystatin C-based estimated glomerular filtration rates (eGFR and eGFR, respectively); however, the associations of protein intake with the eGFR discordance have not been investigated. The present study investigated whether protein intake was associated with the discordance between eGFR and eGFR.
Design And Methods: We cross-sectionally analyzed data from a Japanese community-based cohort including 6,143 participants (50.

The cerebral cortex consists of hierarchically organized areas interconnected by reciprocal axonal projections. However, the coordination of neurogenesis to optimize neuronal production and wiring between distinct cortical areas remains largely unexplored. The somatosensory cortex plays a crucial role in processing tactile information, with inputs from peripheral sensory receptors relayed through the thalamus to the primary and secondary somatosensory areas.

Non-triple helical collagen polypetides (NTHs) are alternative gene products lacking the typical collagen triple-helical structure. This study investigated NTH production in tumor cells and tissues. NTH α1(IV) was detected in various human tumor cell lines and extracted from human lung cancer tissues and tumors in mice.

We aimed to evaluate the correlation between cadaver stature and mandibular bone measurements using three-dimensional (3D) computed tomography (CT) images and develop a stature estimation formula for a Japanese population. In total, 307 and 72 identified cadavers who underwent postmortem CT were selected as the "training" and "validation" datasets, respectively, to derive a stature estimation formula. Four mandibular bone measurements (linear distances between the bilateral mandibular condyles: C-C, from the mental spine to the mandibular condyle: S-C, between the bilateral mandibular foramen: F-F, and from the mental spine to the mandibular foramen: S-F) were obtained from 3D CT-reconstructed images that included only the mandibular bone.

Background: We previously reported that the balance of short-chain fatty acids and lactic acid in feces affects postoperative infectious complications after major hepatectomy. However, the effect remains unclear in pancreaticoduodenectomy.
Methods: Preoperative fecal samples were collected from 210 patients who underwent pancreaticoduodenectomy at 2 institutions between January 2019 and June 2021.

Hierarchically modular organization is a canonical network topology that is evolutionarily conserved in the nervous systems of animals. Within the network, neurons form directional connections defined by the growth of their axonal terminals. However, this topology is dissimilar to the network formed by dissociated neurons in culture because they form randomly connected networks on homogeneous substrates.

IgG4-related disease (IgG4-RD) is an immune-mediated disorder characterized by organ enlargement and dysfunction. The formation of tertiary lymphoid tissues (TLTs) in affected organs is crucial for understanding IgG4-RD, as T follicular helper (Tfh) 2 cells within TLTs drive IgG4+B cell differentiation, contributing to mass formation. Key cytokines IL-4 and IL-10, produced by Tfh2 cells, are essential for this process.

There are hundreds of rare syndromic diseases involving hearing loss, many of which are not targeted for clinical genetic testing. We systematically explored the genetic causes of undiagnosed syndromic hearing loss using a combination of whole exome sequencing (WES) and a phenotype similarity search system called PubCaseFinder. Fifty-five families with syndromic hearing loss of unknown cause were analyzed using WES after prescreening of several deafness genes depending on patient clinical features.

Background: The quality of life (QOL) of ovarian cancer patients is often impaired by refractory ascites. Cell-free and concentrated ascites reinfusion therapy (CART) is a palliative treatment for refractory ascites, but adverse events, such as fever, are problematic. Several cytokines have been suggested to be responsible for the adverse events, but they have not been investigated in detail.

Background: Sarcoglycanopathies (SGPs) are limb-girdle muscular dystrophies (LGMDs) that can be classified into four types, LGMDR3, LGMDR4, LGMDR5, and LGMDR6, caused by mutations in the genes, SGCA, SGCB, SGCG, and SGCD, respectively. SGPs are relatively rare in Japan. This study aims to profile the genetic variants that cause SGPs in Japanese patients.

Background: Aspiration pneumonia, which often recurs due to dysphagia, worsens as patients move between homes, facilities, and hospitals. The impact of pre-hospital living setting on oral intake at discharge remains unclear. The purpose of this study was to identify the effects of the pre-hospital living setting on the nutritional intake route upon discharge in older patients with aspiration pneumonia.

Background: We sought to define textbook outcome in liver surgery (TOLS) for intrahepatic cholangiocarcinoma (ICC) by considering the implications of perioperative outcomes on overall survival (OS).
Methods: Using a multi-institutional database, TOLS for ICC was defined by employing novel machine learning (ML) models to identify perioperative factors most strongly predictive of OS ≥ 12 months. Subsequently, clinicopathologic factors associated with achieving TOLS were investigated.
