Head and neck squamous cell carcinoma (HNSCC) is the major health concern in Indian population. Despite of advanced treatment the mortality rate for this disease has not been improved very much. Current research focused on development of protein marker for the diagnosis and prognosis of HNSCC. The case control study was performed with 125 HNSCC patients and 104 control cases. The level of p50 and IκBα proteins in serum were evaluated at pre and post therapy by label free real time surface plasmon resonance (SPR) and western blot analysis. The serum p50 concentration were significantly (P < 0.0001) higher at the time of diagnosis i.e. pre therapy (Mean ± SD = 27.06 ± 4.88 ng/μl) as compared to controls (Mean ± SD = 16.96 ± 4.04 ng/μl) while it decline at post therapy (Mean ± SD = 21.01 ± 4.98 ng/μl). Similarly, the concentration of IκBα protein in serum were slightly higher at pre therapy (Mean ± SD = 8.33 ± 1.85 ng/μl) as compared to controls (Mean ± SD = 7.27 ± 1.84 ng/μl) and declined at post therapy (Mean ± SD = 7.09 ± 1.24 ng/μl). The level of p50 was also high at the early stage of the disease. The specificity and sensitivity of p50 proteins obtained from ROC analysis revealed the potentiality to be diagnostic protein marker for HNSCC for its accuracy in the study cohort.

Background: Colon adenocarcinoma (COAD) is a leading cause of cancer-related mortality worldwide. Transient receptor potential vanilloid 4 (TRPV4), a calcium-permeable non-selective cation channel, has been implicated in various cancers, including COAD. This study investigates the role of TRPV4 in colon adenocarcinoma and elucidates its potential mechanism via the ferroptosis pathway.

Background: Infertility is a significant issue in spinal cord injury (SCI) patients. Men with SCI often experience erectile and ejaculatory dysfunctions, and low sperm quality leading to impaired fertility. In this study, we investigated the effectiveness of Erythropoietin (EPO)alginate/chitosan (CH-AL) hydrogel on SCI-induced male rat infertility.

Cells are subjected to dynamic mechanical environments which impart forces and induce cellular responses. In age-related conditions like pulmonary fibrosis, there is both an increase in tissue stiffness and an accumulation of senescent cells. While senescent cells produce a senescence-associated secretory phenotype (SASP), the impact of physical stimuli on both cellular senescence and the SASP is not well understood.

Myoglobin (Mb), an important cardiac marker, plays a crucial role in diagnosing, monitoring, and evaluating the condition of patients with cardiovascular diseases. Here, we propose a label-free photoelectrochemical (PEC) sensor for the detection of Mb through target regulated the photoactivity of AgS/FeOOH heterojunction. The AgS/FeOOH nanospindles were synthesized and served as a sensing platform for the fabrication of bio-recognized process for Mb.

Background: Celiac disease (CeD) has shown an association with autoimmune disorders including vitiligo and alopecia areata (AA). Ritlecitinib, a JAK3 and TEC kinase family inhibitor, has been approved for treatment of patients with AA and is in late-stage development for vitiligo. Ritlecitinib inhibits cytotoxic T cells, NK cells, and B cells which play a role in the pathogenesis of CeD.
