The efficacy of photodynamic treatment (PDT) against deep-seated tumor is hindered by low penetration depth of light as well as hypoxic conditions which prevails in tumor. To overcome this limitation, Near-infrared (NIR) absorbing photosensitizers have been investigated actively. In the present study we evaluated the PDT efficacy of an NIR absorbing chlorophyll derivative 'Cycloimide Purpurin-18 (CIPp-18)' in Human Breast carcinoma (MCF-7) and cervical adenocarcinoma (Hela) cells under normoxic and hypoxic conditions.

Pomegranate peel polyphenols (PPP) are natural compounds known for their various biological activities; however, they are easily degraded by environmental conditions, leading to a reduction in their biological activity and health benefits. Therefore, improving the stability of PPP is a critical question that needs to be addressed. This study aimed to evaluate the efficacy of five common microcapsule wall materials-carboxymethyl cellulose sodium (CMCNa), sodium alginate (SA), gum Arabic (GA), beta-cyclodextrin (β-CD), and hydroxypropyl starch (HPS)-in encapsulating PPP to enhance its stability and antioxidant activity.

Background Heart failure (HF) is commonly managed by addressing water and sodium (Na) balance, with arterial circulation playing a major role in influencing renal Na and water excretion. Recently, chloride (Cl) has been recognized as an important factor in HF, associated with volume regulation and its modulation of renin-angiotensin-aldosterone system (RAAS) activity through macula densa signaling, which impacts Na retention and neurohormonal activation. Acetazolamide, a carbonic anhydrase inhibitor, can enhance decongestion in HF by increasing urinary Na and Cl excretion when added to loop diuretics, a mechanism supported by prior studies demonstrating improved urine output and decongestion.

Managing basalt rock cutting waste in an environmentally responsible manner is crucial to mitigate its negative impacts and protect both the environment and human health. Recycling basalt rock cutting waste in geopolymer applications offers multiple environmental, economic, and performance benefits, making it a promising approach for sustainable construction practices. For this purpose, this study concerns about the performance of fiber-reinforced basalt rock-cutting waste-based geopolymer composites at high temperatures up to 1000 °C.

Introduction: For complete blood count, ethylenediaminetetraacetic acid (EDTA) is universally used and has been recognized as the most robust anticoagulant. However, it may lead to pseudothrombocytopenia (PTCT), due to the formation of platelet clumps, which is currently followed by resampling on sodium citrate. Other possible anticoagulants are citrate theophylline adenosine dipyridamole (CTAD) and MgSO.
