After cleaning, precipitation, and resuspension steps, the RNA is ready to be quantified and used for downstream applications. By following this protocol, good yields of high-quality RNA can be obtained from a wide variety of tissues and organisms, and we exemplify the approach here using plant tissues. Some plant tissues contain extra interferents (such as sugars), and for high-quality RNA isolation from those tissues, an alternate protocol is provided. © 2022 The Authors.

Fine-needle aspiration (FNA) biopsies of ameloblastomas are rare in clinical practice, and only a handful of case reports and series have described their cytologic features. We present the case of a 70-year-old woman with a large and disfiguring maxillary sinus soft tissue mass sampled via transcutaneous FNA. Aspirate smears were composed of small clusters of cohesive and monotonous basaloid cells. The accompanying cellblock showed similar clusters of basaloid cells in gland-like, or "adenoid," configurations, eliciting a differential diagnosis that included sinonasal and salivary gland neoplasms. Excisional surgery material was consistent with ameloblastoma with adenoid morphology. Next-generation sequencing (NGS) analysis demonstrated FGFR2 and SMO pathogenic variants. This case exemplifies several uncommonly described features of ameloblastomas in cytology, including cyto-histologic correlation, adenoid morphology, and NGS findings. Awareness of the cytologic features of this neoplasm are important for cytopathologists confronted with maxillary sinus lesions.Chromatin is the genetic material assembled by nucleic acids (including DNA and RNA) and proteins. The biological functions of chromatin are highly dependent on the interaction between DNA (and/or RNA) and proteins that bind to it. Chromatin immunoprecipitation (ChIP) is a powerful technique for evaluating these interactions and has been widely used to characterize the functions of nuclear proteins. However, its application in identifying plant organellar chromatin-binding proteins is lagging. This article describes the method for analyzing the association of chloroplast-localized proteins with the chloroplast genome. © 2022 Wiley Periodicals LLC.

Salmonella contamination of raw meat-based diets (RMBDs) for pets poses a major public health concern but has not been investigated in Japan.
To investigate Salmonella contamination in RMBDs for dogs marketed in Japan and the anti-microbial resistance profiles of the Salmonella isolates.
Sixty commercial RMBD samples were collected in the Okayama and Osaka Prefectures, Japan, between December 2016 and March 2017. The obtained Salmonella isolates were serotyped, their anti-microbial resistance patterns were determined, and the anti-microbial-resistant isolates were screened for the presence of resistance genes by polymerase chain reaction.
Salmonella enterica subsp. enterica was detected in seven of the 60 RMBD samples. Among them, five isolates were identified as S. Infantis (n=3), S. Typhimurium (n=1) and S. Schwarzengrund (n=1), while the serotypes of two isolates were unable to be identified. All isolates were susceptible to ampicillin, cefazolin, cefotaxime and gentamycin. Two isolates were resistant to more than one anti-microbial agent; one of the S. Infantis isolates was resistant to streptomycin, kanamycin, tetracycline and trimethoprim, while the S. Typhimurium isolate was resistant to nalidixic acid, ciprofloxacin and chloramphenicol. The S. Schwarzengrund isolate was resistant to tetracycline. Additionally, the S. Typhimurium isolate harboured the anti-microbial resistance gene gyrA with a mutation corresponding to Ser-83→Phe amino acid substitution.
The study findings suggest that RMBDs for dogs marketed in Japan can be a potential source of Salmonella infection for dogs and humans including infections caused by quinolone-resistant isolates.

The manual analysis of EEG must be conducted by highly trained clinicians or neuro-physiologists; a process that is considered to have a comparatively low inter-rater agreement. Furthermore, the new data interpretation consumes an excessive amount of time and resources. Hence, an automatic seizure detection and prediction system can improve the quality of patient care in terms of shortening the diagnosis period, reducing manual errors, and automatically detecting debilitating events. Moreover, for patient treatment, it is important to alert the patients of epilepsy seizures prior to seizure occurrence. Various distinguished studies presented good solutions for two-class seizure detection problems with binary classification scenarios. To deal with these challenges, this paper puts forward effective approaches for EEG signal classification for normal, pre-ictal, and ictal activities. Three models are presented for tf different signal activities. The third model deals with all signal activities, and it was tested for all patients of the CHB-MIT dataset. It has a superior performance compared to the first models and the state-of-the-art models.
While esophageal squamous cell carcinoma (ESCC) is the predominant histological type in Japan, concern has been expressed over an increase in the proportion of esophageal adenocarcinoma (EAC), especially in middle-aged populations. This study aimed to assess long-term trends in esophageal cancer incidence by histological type.
We used data from three population-based cancer registries in Japan with 10,642 esophageal cancer cases diagnosed between 1993 and 2014. The multiple imputation approach was used to impute a specific histological type (ESCC, EAC, and others) for cases with "Unknown" or missing status. We calculated the age-standardized incidence rates by histological type from 1993 to 2014 and fitted age-period-cohort models to estimate the annual percent changes (APCs) and adjusted incidence rate ratios (IRRs).
After imputation of missing data, the largest mean APC increase was seen in the incidence of EAC in men aged 40-49years (7.1%) followed by those aged 50-59years (5.5%). The age-period-cohort analysis showed that men who were born in the 1960s and later were more likely to develop EAC relative to men who were born in 1950-1959 (1960-1969 cohort, IRR 1.42; 1970-1974 cohort, IRR 2.23), with a period effect indicating a constant increase after 2003. For women, no significant trend in EAC incidence was observed.
The incidence of EAC has increased more prominently compared with that of ESCC, especially in men aged 40-59years, suggesting the impact of increasing obesity in men and a reduction in H. pylori prevalence in Japan.

Molecular investigations by independent research groups around the world have revealed positivity rates ranging from 6.5% to 12.5% in blood samples and up to 14.0% in liver tissue. In this study, we screened an age-stratified collection of feline sera (n = 256) by using an antibody detection enzyme-linked immunosorbent assay based on the recombinant core antigen of DCH (DCHc). Specific antibodies (DCHc Abs) were detected with a prevalence of 25.0%. The DNA of DCH was detected in 35.9% (23/64) of seropositive cats and only in 1.0% (2/192) of seronegative animals. Based on the serological (IgG and IgM anti-DCHc) and virological status, the possible stages of DCH infection were predicted.
The thumb annular pulley system is unique from the other digits and is integral to normal thumb function. Injuries to this pulley system can present a diagnostic challenge. CTx-648 No prior study has evaluated the ability of ultrasound (US) to evaluate all four thumb pulleys.
To validate the sonographic visualization of all four thumb pulleys.
Prospective cadaveric laboratory investigation.
Academic center procedural skills laboratory.
Twelve unembalmed cadaveric hands from seven adult male donors ages 78-89 years with body mass index 21.9-26.6kg/m
.
Based on anatomic descriptions, a single examiner used a standardized protocol and high-frequency linear transducers to identify the A1, variable (Av), oblique (Ao), and A2 pulleys of the thumb in 10 cadaveric hands. As part of the validation process, the presumed Ao pulley was injected with diluted colored latex using US guidance. Two additional cadaveric specimens were dissected for detailed study of the thumb pulley system.
Correlation between the four anatomic pulleys as revealed by dissection and the US findings, including identification of latex location with respect to the Ao pulley.
US correctly identified all four thumb pulleys as distinct anatomic structures and the sonographic appearance of the pulleys correlated with the dissection in all 10 specimens. Latex was observed in the Ao pulley in 100% of the cadavers.
Ultrasound can be used to accurately identify all four thumb pulleys, including distinct Ao and Av pulleys, and should be considered in the evaluation of thumb pulley injuries. This is the first study to validate the US visualization of the annular pulley system of the thumb.

To describe the prevalence, incidence, and progression of radiographic and symptomatic hand osteoarthritis (OA), and to evaluate differences according to age, sex, race, and other risk factors.
Participants were assessed for radiographic and symptomatic hand OA at baseline and year 4 to determine incident disease. A modified Poisson regression with a robust variance estimator was used to account for clustering of joints within fingers within persons to estimate the prevalence ratios and relative risk estimates associated with participant characteristics.
Among 3,588 participants, the prevalence of radiographic hand OA was 41.4%, and the prevalence of symptomatic hand OA was 12.4%. The incidence over 48 months was 5.6% for radiographic hand OA and 16.9% for symptomatic hand OA. Over 48 months, 27.3% of the participants exhibited OA progression. We found complex differences by age, sex, and race, with increasing rates of prevalent hand OA with older age in both men and women, but with rates of incident disease peaking at ages 55-64 years in women.
