The therapeutic role of nutraceuticals targeting the Nrf2/HO-1 signaling pathway in liver cancer.

Liver cancer (L.C.) is the most common cause of cancer death in the United States and the fifth most common globally.

Development and validation of rapid ultra high performance liquid chromatography with tandem mass spectroscopic method for the quantification of N-nitrosodimethyl amine and N-nitrosodiethyl amine in sitagliptin and metformin hydrochloride immediate and extended-release formulations.

A simple, effective LC-MS based method is developed and validated to determine N-nitrosodimethylamine and N-nitrosodiethylamine in pharmaceutical formulations of Sitagliptin and Metformin hydrochloride combination dosage forms. Atlantis T3 (100 × 3 mm, 3 μm) column, eluent-A (0.1% formic acid in water), and eluent-B (0.

A simple isocratic LC method for quantification of trace-level inorganic degradation impurities (ferricyanide, ferrocyanide, nitrite, and nitrate) in sodium nitroprusside injection and robustness by quality using design approach.

This study developed and validated a trace-level quantification inorganic impurities method using reversed-phase HPLC and performed the robustness check using quality-by-design approach by varying the multiple factors simultaneously. This method is economical and simple and exhibits its stability-indicating nature [for the determination of ferrocyanide ([Fe(CN)₆] ), ferricyanide ([Fe(CN) ] ), nitrate (NO ), and nitrite (NO )] in sodium nitroprusside (SNP) drug substance and liquid dosage form. Chromatographic separation was achieved using a USP L43 column (ACE PFP, 150 × 4.

A validated stability-indicating reversed-phase-HPLC method for dipyridamole in the presence of degradation products and its process-related impurities in pharmaceutical dosage forms.

In this study, we developed and validated a method to determine dipyridamole-related impurities in pharmaceutical dosage forms using the reversed-phase-HPLC technique. All impurities were separated on a YMC pack C8 (150 mm × 4.6 mm, 3.

Stability-indicating reversed-phase-HPLC method development and validation for sacubitril/valsartan complex in the presence of impurities and degradation products: Robustness by quality-by-design approach.

According to current regulatory guidelines, a stability-indicating method has been developed to determine the impurities in sacubitril (SCB) and valsartan (VLS) tablet dosage forms and perform robustness studies using the design of experiments approach. The present study was initiated to understand quality target product profile, analytical target profile, and risk assessment for method variables that affect the method response. A reversed-phase-HPLC system was equipped with a Phenomenex Gemini-NX C column (150 × 4.

Combining molecular-marker and chemical analysis of Capparis decidua (Capparaceae) in the Thar Desert of Western Rajasthan (india).

The Thar Desert, a very inhospitable place, accommodates only plant species that survive acute drought, unpredictable precipitation, and those can grow in the limited moisture of sandy soils. Capparis decidua is among one of the few plants able to grow well under these conditions. This species is highly exploited and has been naturally taken, as local people use it for various purposes like food, timber and fuel, although, no management or conservation efforts have been established.

Chemical and genetic diversity among some wild stands of Calligonum polygonoides (Polygonaceae) from the Thar Desert of Rajasthan.

The arid Western Rajasthan, where the Thar Desert of India is immersed, is mostly covered by sand dunes, a common landscape. The region has confronted with fragilities of natural resources, low, erratic and ill-distributed rainfall, and is covered up with many perennial hardy shrubs. Calligonumpolygonoides, the most common perennial shrub, is widely present in some localities of this Thar Desert.
