Biomedical and ecosafety assessment of marine fish collagen capped silver nanoparticles.

In the rapidly evolving landscape of silver nanoparticles (Ag NPs) synthesis, the focus has predominantly been on plant-derived sources, leaving the realm of biological or animal origins relatively uncharted. Breaking new ground, our study introduces a pioneering approach: the creation of Ag NPs using marine fish collagen, termed ClAg NPs, and offers a comprehensive exploration of their diverse attributes. To begin, we meticulously characterized ClAg NPs, revealing their spherical morphology, strong crystalline structure, and average diameter of 5 to 100 nm.

Tumor protein D52 (isoform 3) induces NF-κB - STAT3 mediated EMT driving neuroendocrine differentiation of prostate cancer cells.

In prostate cancer (PCa) patients, a proto-oncogene Tumor protein D52 (TPD52) is overexpressed, and it is involved in different cellular functions. In this study, we report that TPD52 expression is positively associated with the emergence of neuroendocrine PCa (NEPC). With overexpression of TPD52 in LNCaP cells, we found neuroendocrine differentiation (NED) of cells in in-vitro and distinct NED features confirmed by NE markers neuron-specific enolase (NSE) and chromogranin A (CHR-A).

Insect life on earth is greatly diversified despite being exposed to several infectious agents due to their diverse habitats and ecological niche. One of the major factors responsible for their successful establishment is having a powerful innate immune system. The most common and effective method used by insects in recognizing pathogen and non-self-substances is the melanization process among others.

Assessment of water quality and ecosystem health of a canal system during the lockdown period.

The impacts of the lockdown period on water quality and ecosystem health in an artificial canal water system were investigated from the rapidly growing Kozhikode City in India. The ecosystem health is measured in terms of water quality indicators such as pH, electrical conductivity (EC), dissolved oxygen (DO), biological oxygen demand (BOD) and () during the pre-lockdown and lockdown period. The study reveals the massive improvement of the ecosystem health of the canal in terms of DO, BOD, and during the lockdown period.

Pervasive translation of small open reading frames in plant long non-coding RNAs.

Long non-coding RNAs (lncRNAs) are primarily recognized as non-coding transcripts longer than 200 nucleotides with low coding potential and are present in both eukaryotes and prokaryotes. Recent findings reveal that lncRNAs can code for micropeptides in various species. Micropeptides are generated from small open reading frames (smORFs) and have been discovered frequently in short mRNAs and non-coding RNAs, such as lncRNAs, circular RNAs, and pri-miRNAs.

Mosquitoes are potent vectors by serving as agents to life-threatening diseases in humans. Increasing resistance in mosquitoes against existing insecticides and repellents brings new challenges and an opportunity to explore sustainable compounds. We chose six medicinal plants to screen potential bioactive compounds that could act as an insecticide.

Activation of TGF-β - SMAD2 signaling by IL-6 drives neuroendocrine differentiation of prostate cancer through p38MAPK.

Neuroendocrine prostate cancer (NEPC) is an aggressive, androgen independent PCa and it is detected in patients undergoing androgen deprivation therapy (ADT). Interleukin-6 (IL-6) is a pleiotropic cytokine elevated in PCa patients promotes neuroendocrine differentiation (NED). In this study, PCa cells were differentiated with IL-6 in in-vitro to identify novel targets or signaling pathways associated with emergence of NEPC on deprivation of androgens.

Pharmacoresistant Abdominal Seizures in Symptomatic Localization-Related Epilepsy.

Abdominal epilepsy is an uncommon cause of recurrent abdominal pain with or without other complaints seen in children and adults which often goes unnoticed. Here we are presenting a case of abdominal epilepsy in a 7-year boy who had recurrent abdominal pain since many years. He had a history of ventriculoperitoneal shunting which was performed for obstructive hydrocephalus at 1 month and left hemiparesis.

AMPK/SIRT1 signaling through p38MAPK mediates Interleukin-6 induced neuroendocrine differentiation of LNCaP prostate cancer cells.

Neuroendocrine Prostate Cancer (NEPC) is an aggressive form of androgen independent prostate cancer (AIPC), correlated with therapeutic resistance. Interleukin (IL)-6 promotes proliferation and neuroendocrine differentiation (NED) of androgen dependent LNCaP cells. We treated LNCaP cells with IL-6 and observed for in vitro NED of cells and also expression of NE markers βIII tubulin, neuron-specific enolase (NSE) and chromogranin A (ChA).

Treatment in resectable non-metastatic adenocarcinoma of stomach: Changing paradigms.

Adjuvant treatment in gastric adenocarcinoma has been a challenge for the treating specialists, and despite several trials, a clear consensus is yet to be defined. The higher propensity for lymph nodal involvement and locoregional recurrences led to the hypothesis that locoregional and systemic treatments need to be equally aggressive to achieve better outcomes in the management of gastric adenocarcinoma. Regional, ethnic, and biological differences between the Eastern and Western population are also found to reflect in the tumor behavior and its response to treatment.

Novel Paradigm to Record Bilateral Click-Evoked Auditory Brainstem Responses Simultaneously (BiSi-ABR).

Objectives: The current study proposes a new and fast technique to record the auditory brainstem responses (ABRs) simultaneously (BiSi-ABR) from two ears. The BiSi-ABR technique can be used to record the ABRs two times faster than with a conventional ABR recording method. The objective of the study was to show the proof of concept and to compare the BiSi-ABR technique with that of a conventional ABRs recording method to test its clinical feasibility.

Single-fraction radiation: A promising adjuvant therapy to prevent keloid recurrence.

Introduction: Keloids are characterized by collection of atypical fibroblasts with excessive deposition of extracellular matrix components. Keloids are prone to high recurrence (50%-80%) with unimodality treatment. Radiation is a promising approach among the adjuvant modalities in vogue though consensus is lacking on dose-fractionation schedule.

Surgical resection of solitary distant metastasis from locoregionally controlled advanced hypopharyngeal malignancy: A ray of hope.

Head and neck malignancies have always been challenging for the clinician, both with regards to locoregional control and distant metastasis. Aggressive approaches translate to an acceptable locoregional control, but distant failures pose a dilemma. Newer, sophisticated, imaging modalities have helped in early diagnosis of solitary metastasis, and in turn have opened up an array of interventional procedures, which to some extent improve the disease-free survival and quality of life, as was seen in the present case of locoregionally controlled advanced hypopharyngeal malignancy who presented with solitary distant metastasis.
