Design, synthesis, and biological evaluation of novel thiourea derivatives as small molecule inhibitors for prostate specific membrane antigen.

Prostate cancer (PCa) has emerged to be the second leading cause of cancer-related deaths in men. Molecular imaging of PCa using targeted radiopharmaceuticals specifically to PCa cells promises accurate staging of primary disease, detection of localized and metastasized tumours, and helps predict the progression of the disease. Glutamate urea heterodimers have been popularly used as high-affinity small molecules in the binding pockets of popular and well-characterized PCa biomarker, prostate specific membrane antigen (PSMA).

Identification of mitoxantrone as a potent inhibitor of CDK7/Cyclin H via structure-based virtual screening and In-Vitro validation by ADP-Glo kinase assay.

Cyclin-dependent kinases, CDK7 and CDK9 play critical roles in cancer by regulating transcriptional processes essential for cell proliferation and survival. Their dysregulation leads to aberrant gene expression, promoting oncogenic pathways and contributing to tumor growth and progression. This study aimed to identify a new chemotype for CDK7/9 inhibitors using a structure-based virtual screening approach.

Magnetic vortices have recently been proposed for use in a variety of spintronics applications due to their resistance to thermal perturbations, flexibility in changing core polarity, simple patterning procedure, and potential uses in magnetic data storage with substantial density, sensors for the magnetic field, devices for logic operations, and other related fields.

A comprehensive review of computational diagnostic techniques for lymphedema.

Lymphedema is localized swelling due to lymphatic system dysfunction, often affecting arms and legs due to fluid accumulation. It occurs in 20% to 94% of patients within 2 to 5 years after breast cancer treatment, with around 20% of women developing breast cancer-related lymphedema (BCRL). This condition involves the accumulation of protein-rich fluid in interstitial spaces, leading to symptoms like swelling, pain, and reduced mobility that significantly impact quality of life.

Evaluation of Noise in Paediatric Dentistry and Change in Perception of Operators with Use of Ear Protection Devices.

Background: Noise sources in paediatric dental offices include machinery and children's cries and screams. Although the presence of occupational noise-induced hearing loss (ONIHL) among dental operators is established, preventive measures such as ear protection devices (EPDs) are not frequently employed as prophylactic intervention. The primary aim of this study was to quantitatively assess the noise levels in paediatric dental clinics and to qualitatively evaluate the operators' perception of noise with and without the use of EPDs.

Optical Phonon Decay and Improved Thermoelectric Efficiency in p-Type MgSb.

The MgSb-based layered compounds exhibit exceptional thermoelectric properties over a wide temperature range and possess the potential to supplant traditional BiTe modules with reliable and economical MgSb-based thermoelectric devices, contingent upon the availability of a complementary p-type MgSb material with high thermoelectric efficiency comparable to that of n-type MgSb. We provide a simpler method involving the codoping of monovalent atoms (K and Na) at the Mg site of the MgSb lattice to improve the thermoelectric performance of p-type MgSb. K-Na codoping results in a peak power factor of around 0.
