Differences in Breast Cancer Subtypes among Racial/Ethnic Groups.

Background: Differences in the incidence of breast cancer subtypes among racial/ethnic groups have been evaluated as a contributing factor in disparities seen in breast cancer prognosis. We evaluated new breast cancer cases in Hawai'i to determine if there were subtype differences according to race/ethnicity that may contribute to known disparities.

Methods: We reviewed 4591 cases of women diagnosed with breast cancer from two large tumor registries between 2015 and 2022.

Ubiquitination detection techniques.

Ubiquitination is an intricately regulated post-translational modification that involves the covalent attachment of ubiquitin to a substrate protein. The complex dynamic nature of the ubiquitination process regulates diverse cellular functions including targeting proteins for degradation, cell cycle, deoxyribonucleic acid (DNA) damage repair, and numerous cell signaling pathways. Ubiquitination also serves as a crucial mechanism in protein quality control.

Real-time bio-layer interferometry ubiquitination assays as alternatives to western blotting.

Ubiquitination is a crucial cellular pathway enabling normal cellular functions. Abnormalities in the ubiquitination process can lead to cellular dysfunction and cause a range of diseases. Efforts to screen and develop small molecule inhibitors targeting portions of the ubiquitination cascade require rapid and robust methods for detecting ubiquitination.

Diversity of species associated with torch ginger anthracnose.

Anthracnose caused by species is one of the most important diseases of torch ginger. The disease leads to loss of aesthetic and commercial value of torch ginger stems. This study aimed to characterize species associated with torch ginger anthracnose in the production areas of Pernambuco and Ceará.

Racial/Ethnic Differences Among Tumor-Infiltrating Lymphocytes in Breast Cancer Tumors.

Purpose: Tumor-infiltrating lymphocytes (TILs) have emerged as a predictor of breast cancer treatment response and patient outcomes. Current studies investigating racial/ethnic differences in TILs and immune profiles in breast cancer offer varying results. Our study provides some preliminary data in the breast cancer tumor microenvironment where there is a paucity of information, from Asian and Native Hawaiian/Pacific Islander (NHPI) racial/ethnic groups, not well represented in the literature.

Elucidating the Colletotrichum spp. diversity responsible for papaya anthracnose in Brazil.

Papaya (Carica papaya L.) is among the most important tropical fruits produced in Brazil and is grown in nearly every state. However, several diseases can affect papaya production.

Application of whole-genome sequencing for norovirus outbreak tracking and surveillance efforts in Orange County, CA.

Noroviruses are the leading cause of acute gastroenteritis and foodborne illness in the United States. Traditional Sanger sequencing of short genomic regions (~300-600 bp) is the primary method for differentiation of this pathogen; however, whole-genome sequencing (WGS) offers a valuable approach to further characterize strains of this virus. The objective of this study was to investigate the ability of WGS compared to Sanger sequencing to differentiate norovirus strains and enhance outbreak investigation and surveillance efforts.

DNA-based techniques for seafood species authentication.

Global trade of seafood has increased in the last decade, leading to significant concerns associated with seafood fraud. Seafood fraud involves the intentional misrepresentation of fish or shellfish for the purpose of economic gain and includes acts such as species substitution, illegal transshipment, overtreatment/short weighting, and mislabeling country of origin or production method. These fraudulent acts have had economic, environmental, and public health consequences on a global level.

Use of Molecular Methods to Authenticate Animal Species and Tissue in Bovine Liver Dietary Supplements.

Dietary supplements containing bovine (subfamily Bovinae) liver are susceptible to fraud due to their high value and the lack of modern detection methods available for processed animal tissues. The objective of this research was to use molecular methods to authenticate dietary supplements claiming to contain bovine liver or beef liver through the verification of animal species and tissue type. A total of 53 bovine/beef liver dietary supplements were purchased from online sources.

Optimal markers for the identification of Colletotrichum species.

Colletotrichum is among the most important genera of fungal plant pathogens. Molecular phylogenetic studies over the last decade have resulted in a much better understanding of the evolutionary relationships and species boundaries within the genus. There are now approximately 200 species accepted, most of which are distributed among 13 species complexes.

Medical adjuvant treatment to increase patency of arteriovenous fistulae and grafts.

Background: End-stage renal disease (ESRD) patients often require either the formation of an arteriovenous (AV) fistula or an AV interposition prosthetic shunt for haemodialysis. These access sites should ideally have a long life and a low rate of complications (for example thrombosis, infection, stenosis, aneurysm formation and distal limb ischaemia). Although some of the complications may be unavoidable, any adjuvant technique or medical treatment aimed at decreasing complications would be welcome.

Beta blockers for peripheral arterial disease.

Background: Beta (β) blockers are indicated for use in coronary artery disease (CAD). However, optimal therapy for people with CAD accompanied by intermittent claudication has been controversial because of the presumed peripheral haemodynamic consequences of beta blockers, leading to worsening symptoms of intermittent claudication. This is an update of a review first published in 2008.

The effect of ethylene glycol on the phytovolatilization of 1,4-dioxane.

Phytoremediation at contaminated sites is often complicated by the presence of more than one chemical However, the effects of common co-contaminants such as ethylene glycol on the phytoremediation of other chemicals, e.g., 1,4-dioxane, is not well understood.

Beta blockers for peripheral arterial disease.

Background: Beta (ss) blockers are indicated for use in coronary artery disease (CAD). However, optimal therapy for people with CAD accompanied by intermittent claudication has been controversial due to the presumed peripheral haemodynamic consequences of beta blockers, leading to worsening symptoms of intermittent claudication.

Objectives: To quantify the potential harm of beta blockers on maximum walking distance, claudication distance, calf blood flow, calf vascular resistance, and skin temperature when used in patients with peripheral arterial disease (PAD).

Medical adjuvant treatment to increase patency of arteriovenous fistulae and grafts.

Background: End-stage renal disease (ESRD) patients often require either the formation of an arteriovenous (A-V) fistula or an A-V interposition prosthetic shunt for haemodialysis.

Objectives: To determine the effects of adjuvant drug treatment on the patency of fistulae and grafts in patients with ESRD who are undergoing haemodialysis by assessing the number of thrombotic episodes.

Search Strategy: The Cochrane Peripheral Vascular Diseases Group (PVD) searched their Specialised Register (last searched May 2008) and the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library 2008, Issue 2).
