Homogenous catalysis is an essential tool within the commercial manufacture of bulk and fine chemicals. Within this, phosphine ligands, such as tricyclohexylphosphine, otherwise known as CYTOP® 366, are a crucial component. When designing a pathway to your ligand of choice, some key considerations include safety, yield and quality, but at commercial volumes we must also balance cost and consider the technologies readily available. Herein, we report the synthetic route that was chosen to manufacture tricyclohexylphosphine at commercial scale. We also consider, with the use of computational calculations, why traditional hydrophosphination methods failed, where the selected pathway succeeded.

Unlabelled: The World Health Organization (WHO) 2030 roadmap for schistosomiasis calls for development of highly sensitive and specific diagnostic tools to continue and sustain progress towards elimination. Serological assays are excellent for sensitive detection of primary schistosome infections and for schistosomiasis surveillance in near- and post-elimination settings. To develop accurate assay formats, it is necessary to identify defined antibody targets with low cross-reactivity and potential for standardized production.

Introduction: Noncommunicable diseases, especially diabetes and hypertension, have emerged as significant public health challenges. Regular screening, even among healthy individuals, is essential for early diagnosis and prevention of complications.
Methods: This cross-sectional study was conducted in an urban ward of the Sangli-Miraj-Kupwad municipal corporation in Maharashtra, India, and cluster random sampling was used to collect data.

Background And Objectives: A majority of pancreatic malignancies are unresectable at the time of presentation and require EUS-guided fine-needle aspiration or fine-needle biopsy (EUS-FNA/FNB) for diagnosis. With the advent of precision therapy, there is an increasing need to use EUS-FNA/FNB sample for genetic analysis. Next-generation sequencing (NGS) is a preferred technology to detect genetic mutations with high sensitivity in small specimens.

In orofacial pain patients, pain-related temporomandibular disorders (TMD) and neuropathic pain (NP) can both be present. The aim of this cross-sectional study was to examine whether in patients with orofacial pain, associations can be found between (subdiagnoses of) pain-related TMD and NP. Participants were asked to fill in the questionnaires of the Diagnostic Criteria for TMD (DC/TMD) and a screening questionnaire for NP, the Douleur Neuropathique 4 (DN4).
