Estimating the proportion of resistance alleles from bulk Sanger sequencing, circumventing the variability of individual DNA.

Specimens should be examined as much as possible to obtain a precise estimate of the proportion of resistance alleles in agricultural fields. Monitoring traps that use semiochemicals on sticky sheets are helpful in this regard. However, insects captured by such traps are ordinarily left in the field until collection.

Validation of tissue factor pathway inhibitor 2 as a specific biomarker for preoperative prediction of clear cell carcinoma of the ovary.

Background: Tissue factor pathway inhibitor 2 (TFPI2) is a novel serum biomarker that discriminates ovarian clear cell carcinoma (CCC) from borderline ovarian tumors (BOTs) and non-clear cell epithelial ovarian cancers (EOCs). Here, we examined the performance of TFPI2 for preoperative diagnosis of CCC.

Methods: Serum samples were obtained preoperatively from patients with ovarian masses, who needed surgical treatment at five hospitals in Japan.

Effects of Vestibular Rehabilitation on Physical Activity and Subjective Dizziness in Patients With Chronic Peripheral Vestibular Disorders: A Six-Month Randomized Trial.

The present study aimed to determine whether supervised vestibular rehabilitation therapy (VRT) by physical therapists (PTs) affects subjective dizziness in patients with chronic vestibular disorders, and whether supervised VRT-induced changes in subjective dizziness are related to the changes in physical activity levels in daily life. Patients ( = 47) with chronic peripheral vestibular disorders were randomly divided into the VRT group ( = 25) and control group ( = 22). Patients in the VRT group received weekly supervised visits from PTs for a period of 6 months.

Oral care and oral assessment guide in breast cancer patients receiving everolimus and exemestane: subanalysis of a randomized controlled trial (Oral Care-BC).

Background: Oral mucositis is a clinically significant adverse event linked to cancer therapy; it reduces the quality of life of patients and may result in the discontinuation of treatment and a poorer prognosis. Based on level 3 evidence, the Mucositis Study Group of Multinational Association for Supportive Care in Cancer and the International Society of Oral Oncology recommend oral care for all patients receiving cancer chemotherapy and radiotherapy, although no data from large-scaled randomized controlled trials support the efficacy of oral care in preventing oral mucositis. Therefore, this randomized, controlled, multicenter, open-label, phase III study sought to determine whether professional oral care reduces oral mucositis in everolimus and exemestane-treated estrogen receptor-positive metastatic breast cancer patients.

Impact of the 12-gene recurrence score assay on deciding adjuvant chemotherapy for stage II and IIIA/B colon cancer: the SUNRISE-DI study.

We conducted this prospective study to evaluate whether the 12-gene recurrence score (12-RS) assay affected physicians' recommendations on adjuvant treatment selection.

Patients And Methods: Patients with stage IIIA/IIIB or stage II colon cancer were enrolled.

Antigenic differences between equine influenza virus vaccine strains and Florida sublineage clade 1 strains isolated in Europe in 2019.

From late 2018 to 2019, equine influenza virus (EIV) strains of Florida sublineage clade 1 (Fc1), which had until then been circulating mainly in the United States, suddenly spread across Europe causing many outbreaks, and Florida sublineage clade 2 (Fc2) strains, which had been circulating mainly in Europe, have not been detected in Europe since 2018. Since 2010, the World Organisation for Animal Health (OIE) has recommended that EIV vaccines contain an Fc1 strain that is like A/equine/South Africa/4/2003 or A/equine/Ohio/2003. Accordingly, Japanese vaccines contain A/equine/Ibaraki/1/2007 as the Fc1 strain.

Machine learning-based image analysis for accelerating the diagnosis of complicated preneoplastic and neoplastic ductal lesions in breast biopsy tissues.
