m.ny studies have been done and m.ny results have been established for studying cancers in hum.n and the ways of treating it. However, one thing that rem.ins relevant is the study m.del that is used to diagnose, cure or conclude treatm.nt m.thods for hum.n cancers. The scientists have tried som. ways to link the data and tried to analyze the m.licious disease in various anim.l m.dels in order to solve the problem.for hum.ns. Out of all the m.dels, scientists have preferred dogs as the m.st suitable m.del and conducted studies on them. Our article will review the reason for preferences given to dog as a study m.del and what the previous studies have tried to conclude by considering the dreaded disease in dogs. Our article has focused on m.st of the recent observations and tried to elucidate the reasons/preferences for studying cancer disease in dogs (scientific nam.;Canis Lupus fam.liaris). We will also talk about the idea of com.arative oncology program. that m.ny centers adapt in order to study the disease called cancer.

The sandstones of the Late m.ocene–Pliocene Dibdibba Form.tion in the Najaf–Karbala Plateau and Basra were exam.ned to determ.ne their source rocks and origin. The rare earth elem.nts(REE) and trace elem.nts(Sc, Co, V, and Th) concentrations in these sandstones revealed that they likely derived from.a single source. The steep light rare earth elem.nts(LREE) and flat, heavy rare earth elem.nt(HREE) patterns, negative Eu anom.ly, and high ΣREE contents in sandstones suggest its derivation from.a suggests that a passive continental m.rgin environm.nt and originated from.felsic source rocks. The average concentration of ΣREE is 93.5 ppm. which is lower than that of the average crustal com.ositions like Upper Continental Crust and Post Archean Australian Shale. The higher proportion of LREE com.ared to HREE im.lies that these sandstones were recycled and derived from.a distal source. The Th/Co, Th/Sc, La/Sc, La/Co, Eu/Eu*and(La/Lu)cn elem.ntal ratios indicated that these Late m.ocene–Pliocene sandstones were derived from.felsic rocks located in the m.rginal region of the Arabian Shield.

In recent years, there has been an increase in concern regarding the effects of paracetam.l poisoning on liver tissues, particularly when consum.d in large am.unts. Som. studies have estim.ted that paracetam.l is involved in 56% of acute liver diseases, whereas 0.4% of paracetam.l overdose cases result in fatal-ity. In this study, the effects of m.ringa oleifera on paracetam.l toxicity in the liver were explored. It has been dem.nstrated that m.ringa oleifera is highly nu-tritious, contains bioactive m.lecules, and is therapeutically beneficial. m.ny studies have shown that m.ringa oleifera leaves possess a wide range of biologi-cal properties, including antioxidant, tissue protection, analgesic, antihyperten-sive, and im.unom.dulatory activities. This study highlights the protective role of m.ringa oleifera on handling possible paracetam.l hepatotoxicity in m.le rats. .
