Background & Aims: Exercise therapy is a potentially beneficial treatment option for chemotherapy-induced peripheral neuropathy (CIPN). However, there is a lack of consensus on the management of CIPN in patients with ovarian cancer. The purpose of this scoping review was to evaluate the evidence on the effectiveness of exercise therapy in patients with ovarian cancer and explore key physical fitness parameters.

The majority of theoretical analyses of evolutionary algorithms in the discrete domain focus on binary optimization algorithms, even though black-box optimization on the categorical domain has a lot of practical applications. In this paper, we consider a probabilistic model-based algorithm using the family of categorical distributions as its underlying distribution and set the sample size as two. We term this specific algorithm the categorical compact genetic algorithm (ccGA).

Enantioselective halolactonizations of sterically less hindered alkenoic acid substrates without substituents on the carbon-carbon double bond have remained a formidable challenge. To address this limitation, we report herein the asymmetric bromolactonization of 5-hexenoic acid derivatives catalyzed by a BINOL-derived chiral bifunctional sulfide.

Article Synopsis
  • The study aimed to analyze treatment patterns for biliary tract cancer (BTC) in Japan and investigate how often biliary infections affect treatment.
  • Data was collected from over 22,000 patients diagnosed with BTC who received systemic therapies between 2011 and 2020, revealing that most patients were older males with extrahepatic cholangiocarcinoma being the most common type.
  • Findings indicated that nearly 30% of patients experienced treatment delays due to biliary infections, with specific details on antibiotic duration and timing of infections occurring during therapy.

Both natural and unnatural amino acids, peptides, and proteins are widely recognized as green and sustainable organic chemicals, not only in the field of biological sciences but also in materials science. It has been discovered that artificially designed unnatural peptides and proteins exhibit advanced properties in medical and materials science. In this context, the development of precise chemical modification methods for amino acids and peptides is acknowledged as an important research project in the field of organic synthesis.
