Evaluation of serum concentrations of total protein and gamma-globulin as an indicator of serum immunoglobulin G concentration in dairy calves.

The aim of this study was to evaluate precision of estimating serum IgG concentration from total protein (TP) or gamma-globulin (γGLB) concentration as an alternative approach, and to compare morbidity of preweaning dairy calves differing in serum γGLB concentration. In trial 1, blood was sampled from 129 Holstein calves in the first week after birth, and serum concentrations of TP, γGLB, and IgG were measured. Spearman's correlation coefficient (r) between serum IgG and TP concentrations was 0.

Soft tissue tumor with BRAF and NRAS mutations sharing features with NTRK-rearranged spindle cell neoplasm: A case report expanding the spectrum of spindle cell tumor with kinase gene alterations.

NTRK-rearranged spindle cell neoplasm is a group of tumors characterized by NTRK1/2/3 gene fusion. Recently, tumors with other kinase fusion genes were reported to exhibit similar morphologies. Herein, we discuss an adult-onset soft tissue tumor with similar histologic patterns as kinase gene fusion-related tumors but with BRAF and NRAS mutations.

A Pathological Assessment of the Microvasculature of Biliary Tract Neoplasms Referring to Pre-Existing Blood Vessels and Vessel Co-Option.

There are several types of microvasculature supplying neoplasms: "newly formed blood vessels" (neoangiogenesis), which are a component of the tumor microenvironment (TME) of invasive carcinoma with wound healing-like reaction; and "pre-existing blood vessels", which are used as tumor-supplying vessels by neoplasms (co-option vessels) and are likely to develop in hypervascularized organs. We herein review the microvasculature of neoplasms of biliary tract with reference to pre-existing vessels and vessel co-options. In the hepatobiliary system, intrahepatic large and extrahepatic bile ducts (large bile ducts) and the gallbladder as well as hepatic lobules are highly vascularized regions.

A Gene Expression Signature that Predicts Gastric Cancer Sensitivity to PARP Inhibitor Therapy.

Background/aim: Biomarkers indicating sensitivity to poly ADP-ribose polymerase (PARP) inhibitors have not yet been identified in gastric cancer. PARP inhibitors target homologous recombination deficiency (HRD); however, homologous recombination (HR) induces complex changes in gene expression, which makes it difficult to identify reliable biomarkers. In this study, we identified a multi-gene expression signature as a marker of PARP inhibitor sensitivity in gastric cancer.

Biphenotypic sinonasal sarcoma diagnosed by detection of fusion gene using integrated whole-genome and transcriptome sequencing.

Biphenotypic sinonasal sarcoma (BSNS) is a double-phenotype sarcoma that shows differentiation in both the nervous and muscular systems. To date, whole-genome and transcriptome sequencing (WGTS) has not been used to analyze BSNS. We report a patient with BSNS who was diagnosed based on rearrangement using WGTS.

The composition of early lactation milk in recipient dairy cows determines success in bovine embryo transfer.

To identify new criteria for selecting recipient dairy cows for embryo transfer (ET), we retrospectively examined the effects of the composition of early lactation milk on fertility risk in ET. This study investigated the association between milk fat (FAT), milk protein (PRO), and milk urea nitrogen (MUN) levels during early lactation, based on production records, and subsequent fertility risk in ET using contingency table analysis and multivariable logistic regression analysis, which included five confounding variables. The results showed that MUN levels during early lactation were negatively associated with fertility risk in ET, while FAT and PRO levels showed no clear association.

Insights into E-Cadherin Impairment in -Unaltered Invasive Lobular Carcinoma: A Comprehensive Bioinformatic Study.

Invasive lobular carcinoma exhibits unique morphological features frequently associated with alterations in . Although some studies have identified abnormalities in adhesion factors other than E-cadherin, the molecular mechanisms underlying E-cadherin abnormalities in -unaltered invasive lobular carcinoma remain poorly understood. In this study, we investigated the molecular underpinnings of E-cadherin dysregulation in invasive lobular carcinoma in the absence of gene alterations, using comprehensive bioinformatic analyses.

Clinical Implications of the Degree of Pancreatic Invasion in Ampulla of Vater Carcinoma.

Background: Ampulla of Vater carcinoma (AVC) stage T3 was subdivided according to the degree of pancreatic invasion into T3a (≤ 0.5 cm) and T3b (> 0.5 cm) by the 8th edition of the Union for International Cancer Control (UICC)/American Joint Committee on Cancer (AJCC) cancer staging system.

Efficacy of mini-endoscopic combined intrarenal surgery for pediatric kidney calculi: a single center retrospective study.

Management of large pediatric kidney calculi (PKC) is challenging. This study aimed to evaluate the efficacy and safety of miniature endoscopic combined intrarenal surgery (mini-ECIRS) for PKC. We retrospectively analyzed mini-ECIRS in 16 pediatric patients undergoing kidney stone treatment between November 2014 and October 2023 to determine its safety, efficacy, and associated outcomes.

Effects of cashew nutshell liquid on milk production and methane emission of dairy cows in a farm condition.

This study aimed to clarify the efficacy of cashew nutshell liquid (CNSL) in methane emissions, milk production, and rumen fermentation of lactating cows in practical conditions. Ten Holstein lactating cows were used in a free-stall barn with a milking robot. Two treatments were arranged as control (no CNSL additive, n = 5) or CNSL addition (10 g/day of CNSL, n = 5) for 21 days after the 7-day preliminary period.

Pathologic characterization of precursors and cholangiocarcinoma referring to peribiliary capillary plexus: a new pathologic approach to bile duct neoplasm.

The peribiliary capillary plexus (PCP) regularly and densely lines the basal side of the lining epithelia of normal bile ducts. To determine the pathology of the PCP in high-grade biliary intraepithelial neoplasms (BilINs) and intraductal papillary neoplasms of the bile duct (IPNBs), a precursor of cholangiocarcinoma (CCA), and CCA. Seventy-six cases of surgically resected high-grade BilIN and 83 cases of IPNB were histopathologically examined using endothelial immunostaining of PCP; all cases of high-grade BilIN and 40 cases of IPNB were associated with invasive CCA.

Subdivision of pT1N0 (American Joint Committee on Cancer 8th edition) distal cholangiocarcinoma for adjuvant chemotherapy consideration.

Background: The adjuvant S-1 trial affirmed adjuvant chemotherapy for biliary tract cancer but excluded pT1N0 distal cholangiocarcinoma (DCC) according to the seventh edition of the American Joint Committee on Cancer (AJCC) classification. The introduction of tumor depth of invasion (DOI) for T-classification in the eighth edition complicates identifying DCC patients less likely to benefit from adjuvant chemotherapy.

Methods: Our cohort consisted of 185 patients with DCC who underwent pancreaticoduodenectomy between 2002 and 2019.

Defining a learning curve for urology trainees to achieve renal access without complications in endoscopic combined intrarenal surgery.

Objectives: There is a lack of data on the number of surgeries required for endoscopic combined intrarenal surgery (ECIRS). Accordingly, we aimed to identify the learning curve for ECIRS performed by multiple surgeons.

Methods: We included 296 patients who underwent ECIRS at our university hospital between 2016 and 2021.

Effect of milking time on yield, composition, and antimicrobial components of milk in lactating goats.

Various studies have attempted to improve the milk yield and composition in dairy animals. However, no study has examined the effects of milking at different times on milk yield and composition. Therefore, this study aimed to compare the yield, composition, and antimicrobial components of milk obtained from milking at different times in lactating goats.

Non-contrast-enhanced breast MRI for evaluation of tumor volume change after neoadjuvant chemotherapy.

Purpose: Three-dimensional contrast-enhanced magnetic resonance imaging (3D-Ce-MRI) is a most powerful tool for evaluation of neoadjuvant chemotherapy (NAC). However, the use of contrast agent is invasive, expensive, and time consuming, Thus, contrast agent-free imaging is preferable. We aimed to investigate the tumor volume change after NAC using maximum intensity projection diffusion-weighted image (MIP-DWI) and 3D-Ce-MRI.

Effect of feeding calf starter with calcium salts of medium-chain fatty acids on the growth and metabolic hormones in calves.

We investigated the effects of a calf starter supplemented with calcium salts of medium-chain fatty acids (MCFA-Ca) on growth and plasma hormone concentration in calves. Twelve Holstein calves were randomly assigned to two dietary groups (without supplementation [CON] and supplemented with MCFA-Ca [MCFA]) from 4 d of age. Calves were fed 1.

Tumor cell enrichment by tissue suspension improves sensitivity to copy number variation in diffuse gastric cancer with low tumor content.

The detection of copy number variations (CNVs) and somatic mutations in cancer is important for the selection of specific drugs for patients with cancer. In cancers with sporadic tumor cells, low tumor content prevents the accurate detection of somatic alterations using targeted sequencing. To efficiently identify CNVs, we performed tumor cell enrichment using tissue suspensions of formalin-fixed paraffin-embedded (FFPE) tissue sections with low tumor cell content.

Tafamidis medication adherence and persistence in patients with transthyretin amyloid cardiomyopathy in Japan.

Aims: This study aimed to describe baseline characteristics and adherence among patients with transthyretin amyloid cardiomyopathy (ATTR-CM) treated with tafamidis (VYNDAQEL®) in Japan using the Japanese Medical Data Vision (MDV) database.

Methods And Results: This study was a non-interventional, retrospective cohort study of adult (≥18 years old) patients in the Japanese MDV claims database diagnosed with ATTR-CM and with at least two tafamidis prescriptions of dose strength 4 × 20 mg/day between 1 March 2019 and 31 August 2021. The date of the first prescription was defined as the index date, with follow-up time defined as the time between the first and last prescription plus the days' supply from the last refill.
