This article explains a step-wise protocol to develop an electrochemical sensor to quantify serum levels of C-telopeptide (CTX) crosslinks also known as crosslaps in a matter of minutes and with high level of accuracy. The technique needs only one-step (incubation) and can thus be used for point of care screening. Due to the excellent electrical properties of the as-prepared immunosensor, CTX levels were successfully measured from 1 to 1000 pg/mL. This is while the normal reference of the marker is 50-450 pg/mL, suggesting that the sensor can acceptably detect CTX. The results also showed a good correlation with ECLIA in measuring serum levels of CTX.

Novichok nerve agents, such as A-230, A-232, and A-234, were classified as Schedule 1 chemicals under the Chemical Weapons Convention (CWC) by the Organisation for the Prohibition of Chemical Weapons (OPCW) following poisoning incidents in 2018. As a result, the production, storage, and use of these chemicals are strictly prohibited by CWC signatory nations. The identification of biomarkers indicating Novichok exposure in humans is crucial for prompt detection and response to potential incidents involving these banned chemical weapons.

Myocardial infarction (MI) is a coronary artery-related disease that seriously threatens human life and is the leading cause of sudden death worldwide, where a lack of nutrients and oxygen leads to an inflammatory response and death of cardiomyocytes. Ferroptosis is a form of non-apoptotic cell death associated with metabolic dysfunction, resulting in abnormal breakdown of glutamine and iron-dependent accumulation of reactive oxygen species (ROS) during metabolism. However, the molecular mechanism of ferroptosis in the pathogenesis of MI and the function of Klotho and KRAS on ferroptosis during MI remain unclear.

Background: The therapeutic targeting of the intestinal microbiota has gained increasing attention as a promising avenue for addressing mood disorders. This study aimed to assess the potential effect of supplementing standard pharmacological treatment with the probiotic kefir in patients with Major Depressive Disorder (MDD).
Methods: Thirty-eight female participants diagnosed with moderate MDD by the Hamilton Rating Scale for Depression (HAM-D) were selected to receive the probiotic kefir in conjunction with antidepressant therapy for 12 weeks.

Background: Sirtuins and FoxO1 are reported to be important in the pathophysiology of preeclampsia. This study aimed to investigate whether serum FoxO1 and SIRT2 concentrations differ between preeclampsia and normal pregnancy and also to compare these markers in early- and late-onset preeclampsia.
Methods: This cross-sectional study was conducted on 27 women with early-onset preeclampsia, 27 women with late-onset preeclampsia, and 26 healthy normotensive pregnant controls.

Baicalein, one of the major active flavonoids found in Scutellaria baicalensis, has been revealed to exhibit potent anti-inflammatory properties in allergic airway inflammation. This study aimed to explore the role of baicalein and its relevant mechanism in the treatment of allergic rhinitis (AR). The bioinformatics tools were used to predict the targets of baicalein and AR-related genes.
