Biological evaluation of trans-2,3-dihydrofuro[3,2-c]coumarins as potential cathepsin inhibitors and anticancer agents.

Novel trans-2,3-dihydrofuro[3,2-c]coumarins were synthesized and assessed for their inhibition potential against cysteine proteases: cathepsin B, H and L which are the possible targets for anticancer activity. In general, the coumarin derivatives were found to be exceptional inhibitors against this class of enzymes. On the basis of molecular modeling data and structure-activity relationships, their inhibition patterns are also discussed.

Naphthoquinone fused diazepines targeting hyperamylasemia: potential therapeutic agents for diabetes and cancer.

Elevated levels of amylase in the blood, known as hyperamylasemia, have been correlated with diabetes and cancer. To investigate the impact of hyperamylasemia on cellular proliferation, it is imperative to design dual inhibitors targeting both α-amylase activity and cancer progression. Naphthoquinone fused diazepines have been synthesized using multicomponent reaction with high Eco-score of 87 and evaluated for bio efficacy using antioxidant and α-amylase inhibition assay.

Improved Conductance Blockage Modeling of Cylindrical Nanopores, from 2D to Thick Membranes.

The ionic current blockage from a nanopore sensor is a fundamental metric for characterizing its dimensions and identifying molecules translocating through it. Yet, most analytical models predicting the conductance of a nanopore in both open and obstructed states remain inaccurate. Here, using an oblate spheroidal coordinate framework to study the electrical response of nanopore access regions, we reveal that the widely used model from Kowalczyk et al.

Global perspectives on heart disease rehabilitation and secondary prevention: a scientific statement from the Association of Cardiovascular Nursing and Allied Professions, European Association of Preventive Cardiology, and International Council of Cardiovascular Prevention and Rehabilitation.

Cardiovascular disease is a leading cause of death, morbidity, disability, and reduced health-related quality of life, as well as economic burden worldwide, with some 80% of disease burden occurring in the low- and middle-income country (LMIC) settings. With increasing numbers of people living longer with symptomatic disease, the effectiveness and accessibility of secondary preventative and rehabilitative health services have never been more important. Whilst LMICs experience the highest prevalence and mortality rates, the global approach to secondary prevention and cardiac rehabilitation, which mitigates this burden, has traditionally been driven from clinical guidelines emanating from high-income settings.

Biosimilars in Oncology: Latest Trends and Regulatory Status.

Biologic-based medicines are used to treat a variety of diseases and account for around one-quarter of the worldwide pharmaceutical market. The use of biologic medications among cancer patients has resulted in substantial advancements in cancer treatment and supportive care. Biosimilar medications (or biosimilars) are very similar to the reference biologic drugs, although they are not identical.

Predicting pattern of coronavirus using X-ray and CT scan images.

Novel coronavirus is a disease that can propagate easily with very minute carelessness and with very little physical contact between people. Presently, the world's central health institution called the World Health Organization has approved and advised the Reverse Transcription-Polymerase Chain Reaction (RT-PCR) swab test as the most important and effective diagnostic method to confirm if a patient has COVID-19 symptoms or not. This test takes at least a day for revealing the results, depending on the feasible resources in the neighborhood.

Correction: Electro-organic synthesis: an environmentally benign alternative for heterocycle synthesis.

Electro-organic synthesis: an environmentally benign alternative for heterocycle synthesis.

Heterocyclic compounds are considered to be one of the most established structural classes due to their extensive application in agrochemicals, pharmaceuticals and organic materials. Over the past few years, the development of heterocyclic compounds has gone through a considerable renaissance from conventional traditional methodologies to non-conventional electro-organic synthesis. Replacing metal catalysts, strong oxidants and multi-step methodologies with metal and strong oxidant-free single-step protocols has revolutionized the field of sustainable organic synthesis.

The series of a four-node motif and coherent type-1 feed-forward loop can provide sensitive detection over arbitrary range of input signal, thereby explain Weber's law in higher-order sensory processes, and compute logarithm.

Weber's law states that the ratio of the smallest perceptual change in an input signal and the background signal is constant. The law is observed across the perception of weight, light intensity, and sound intensity and pitch. To explain Weber's law observed in steady-state responses, two models of perception have been proposed, namely the logarithmic and the linear model.

Cabazitaxel versus abiraterone or enzalutamide in poor prognosis metastatic castration-resistant prostate cancer: a multicentre, randomised, open-label, phase II trial.

Background: Treatment of poor prognosis metastatic castration-resistant prostate cancer (mCRPC) includes taxane chemotherapy and androgen receptor pathway inhibitors (ARPI). We sought to determine optimal treatment in this setting.

Patients And Methods: This multicentre, randomised, open-label, phase II trial recruited patients with ARPI-naive mCRPC and poor prognosis features (presence of liver metastases, progression to mCRPC after <12 months of androgen deprivation therapy, or ≥4 of 6 clinical criteria).

Automation in signal management in pharmacovigilance-an insight.

Drugs are the imperial part of modern society, but along with their therapeutic effects, drugs can also cause adverse effects, which can be mild to morbid. Pharmacovigilance is the process of collection, detection, assessment, monitoring and prevention of adverse drug events in both clinical trials as well as in the post-marketing phase. The recent trends in increasing unknown adverse events, known as signals, have raised the need to develop an ideal system for monitoring and detecting the potential signals timely.

Timing of Palliative Care Referral Before and After Evidence from Trials Supporting Early Palliative Care.

Background: Evidence from randomized controlled trials has demonstrated benefits in quality of life outcomes from early palliative care concurrent with standard oncology care in patients with advanced cancer. We hypothesized that there would be earlier referral to outpatient palliative care at a comprehensive cancer center following this evidence.

Materials And Methods: Administrative databases were reviewed for two cohorts of patients: the pre-evidence cohort was seen in outpatient palliative care between June and November 2006, and the post-evidence cohort was seen between June and November 2015.

Photodermatitis in a woman with infiltrating intraductal breast carcinoma: An uncommon adverse cutaneous drug reaction of paclitaxel revisited.

Paclitaxel-induced photodermatitis is extremely rare despite the frequent use of paclitaxel-trastuzumab combination chemotherapy. A 70-year-old woman with infiltrating intraductal breast cancer developed photodermatitis after ten treatment courses of weekly paclitaxel-trastuzumab combination chemotherapy. Withdrawal of paclitaxel and sun avoidance led to its resolution.
