Introduction: Recent studies have shown an increase in the prevalence of early-onset colorectal cancer (CRC) in people aged 20-49 compared to those aged 50-74, with a more rapid increase in the younger age groups. Poorly differentiated, left-sided, and rectal tumors were more common in young adults than in older adult CRC patients. We aimed to improve the understanding of early-onset CRC and to guide primary care physicians on strategies to mitigate its impact.

Article Synopsis
  • Understanding liver regeneration mechanisms is essential for improving liver surgeries, as partial hepatectomy is commonly used for liver issues.
  • Hepsin, a serine protease, is shown to encourage hepatocyte (liver cell) growth and division, increasing liver size by activating the EGFR-Raf-MEK-ERK pathway.
  • Administering Hepsin post-surgery boosts liver regeneration without causing lasting problems like liver fibrosis or cancer, indicating promising prospects for clinical applications in liver recovery.

RNA interference (RNAi) is a primordial biological process that protects against external intrusion. SiRNA has the potential to selectively silence disease-related genes in a sequence-specific way, thus offering a promising therapeutic approach. The efficacy of siRNA-based therapies in cancer treatment has gained significant recognition due to multiple studies demonstrating its ability to effectively suppress cancer cells' growth and multiplication.

Alzheimer's disease (AD) is characterized by the aggregation of amyloid β (Aβ) peptides and the formation of plaques in the brain, primarily derived from the proteolytic degradation of amyloid precursor protein (APP). Cathepsin B (CatB) is a cysteine protease that plays a pivotal role in this process, making it a potential target for the development of anti-Alzheimer's therapies. Apart from AD, CatB is implicated in various physiological and pathological processes, including cancer.

The purpose of the current study was to analyze and validate the existing gap in knowledge, by conducting a differential expression analysis and validation of NEK6, NEK7, and NEK9 in breast, cervical, and glioblastoma cancer and targeting these proteins through development of novel site specific inhibitor with favorable pharmacokinetic and safety profile, using open-source databases. The analysis revealed that the targeted kinases were overexpressed in all three types of cancer. Their expression was significantly linked to overall survival rates, which suggests that they play a major role in the development and progression of these cancers.

Background: PD-L1 is associated with poor efficacy of first- or second-generation epidermal growth factor receptor (EGFR) tyrosine kinase inhibitors (TKIs) in untreated EGFR-mutant non-small-cell lung cancer (NSCLC). Whether PD-L1 is also predictive of osimertinib efficacy in pre-treated patients with an acquired EGFR T790 M mutation is unclear.

Patients And Methods: PD-L1 expression and tumor microenvironments were evaluated in tumors from EGFR-mutant T790 M + NSCLC patients treated with osimertinib.

Although multiple studies suggest that ionizing radiation can induce bystander effects (radiation-induced bystander effect, RIBE) in cultured cell lines, it is still unclear whether RIBE is evolutionarily conserved in invertebrates. In this study, we investigated the frequency of cell death of unirradiated starfish (Patiria pectinifera) oocytes co-cultured with oocytes irradiated with X rays (0, 2 and 4 Gy). We observed increased frequencies of cell death determined by morphological abnormality and TUNEL-positive cells in unirradiated oocytes co-cultured with oocytes irradiated with 2 Gy or 4 Gy oocytes.

Objective: The aim of the study was to compare the cost and clinical impact of repeating BioFire FilmArray gastrointestinal (GI) and respiratory (RP) panel assays with 3 vs 4 pathogen targets positive.

Method: We analyzed 12,027 GI and RP panels to evaluate our retesting policy, which retested panels with 3 or more detected pathogens (3-pathogen protocol) compared with the manufacturer's 4-pathogen (4-pathogen protocol) recommendation. We compared the retesting results, calculated the cost implications, and reviewed the clinical impact on antibiotic prescriptions and patient outcomes.

Article Synopsis
  • Paclitaxel (PTX) is a key chemotherapy drug effective against multiple cancers, but the development of resistance in patients leads to frequent cancer recurrence.
  • Mechanisms of resistance include changes in β-tubulin, drug efflux pathways, and alterations in proteins that control cell death.
  • Long non-coding RNAs (lncRNAs) are implicated in these resistance mechanisms and may serve as promising targets for new therapeutic strategies to combat drug resistance in cancer treatment.

The metabolic syndrome (MetS) is a clustering of abdominal obesity, hypertension, hyperglycaemia, hypertriglyceridemia and low high-density lipoprotein (HDL) level. MetS development is affected by endocrine hormones such as prolactin (PRL) hormone which induce insulin resistance and central obesity because PRL is implicated in the pathogenesis of MetS. Pituitary PRL controls mammary gland, however extra-pituitary PRL is highly intricate in the regulation of adipose tissue function.
