ABSTRACT
Aim of Study: The aim of this study is to correlate the prominin-1 or CD133 association with functional pathway markers of cancer stemness in Indian triple-negative breast cancer (TNBC) patient samples. Materials and Methods: TNBC samples were confirmed for the absence of hormone receptors (estrogen receptor–ER/progesterone receptor) and human epidermal growth factor receptor-2 or proto-oncogene neu or erbB2 or CD340 by immunohistochemical analysis. Formalin-fixed paraffin-embedded samples of patients were used to collect the total RNA. Then, one-step reverse transcription-polymerase chain reaction (RT-PCR) was used to detect the cancer stemness-related transcript levels in the different samples. The RT-PCR products were analyzed semi-quantitatively on agarose gels. The band intensities of respective samples for different transcripts were analyzed by densitometry. Results: TNBC-confirmed samples had shown increased levels of CD133 transcript than control tissues. Further, elevated CD133 transcripts are correlated with higher transcript levels of NOTCH1/FZD7/transforming growth factor-beta receptor Type III R/patched-1 pathway mediators. Conclusions: This work has clearly indicated that there is a correlation between CD133 and functional pathways that control cancer stem cells in TNBC. These observations may indicate the possible association between cancer stemness and TNBC malignancy
ABSTRACT
Hemangioendothelioma (HE) is a rare primary bone tumor of vascular origin constituting 0.5–1% of primary malignant bone tumors. Here, we report the clinical and histopathological features of a 38-year-old male who presented with multifocal lesions involving the left scapula, left proximal humerus, and the left ulnar olecranon process which was diagnosed as metastatic lesion radiologically and clinically. The final diagnosis of retiform HE was made on the basis of histopathology.
ABSTRACT
Introduction: Giving more fluid causes edema and less gives rise to hypoperfusion causing improper delivery of oxygen and substrate leads to cellular dysfunction and multiorgan dysfunction involving the brain, liver, kidneys, heart, lungs and causing death. Diffusion, filtration, osmosis and adequate reabsorption help in continuous exchange of water and solutes among compartment. Daily water intake from the food and water get equalized with losses in the kidneys as urine, from the gastrointestinal system as feces and evaporation of water through lung and skin. Various hormones like Angiotensin II, Aldosterone ADH, Atrial natriuretic peptide maintain sodium and water balance and hence volume status. To maintain normovolemia there is every need for meticulous evaluation for patient Volume status in each patient for adequate volume replacement. Aim of the study: Correlating the Clinical Assessment of Volume Status to the volume assessment By Echocardiography using Respiratory Variation in Inferior Vena Cava Diameter. Gnanaprakasam J, Vasantha Kumar M, Praveenkumar M, Lakshmi Priya R. Study on clinical assessment of volume status and correlation to the respiratory variation in inferior vena cava diameter by echocardiography, a non-invasive method of measuring volume status. IAIM, 2018; 5(5): 104-110. Page 105 Materials and methods: Study population consisted of 200 patient of medicine department both inpatient and outpatient of Chengalpattu Medical college. The patient was examined clinically, history suggestive of volume depletion and history suggestive of volume overload were noted, signs and symptoms of both hypovolemia and hypervolemia were noted. Echocardiography was used as a noninvasive method of measuring volume status. Results: Correlation of assessment of volume status by the clinical method and IVC method as low, normal and high was represented. Correlation – 0.797, P value < 0.001 which tell that there was a statistically significant correlation between your two variables. That means, increases or decreases in IVC do significantly relate to increase or decrease. Conclusion: The use of echocardiography as a non-invasive mode of volume assessment is helpful to empower the clinical assessment methods and hence improves diagnostic accuracy.
ABSTRACT
The aqueous solution of methylene blue(MB) has been subjected to Photocatalytic degradation by UV radiation in presence of TiO2 photo-catalyst containing different concentrations of H2O2. The experiments conducted at different dye concentrations (12 and 20 ppm), catalyst loading, pH and H2O2 dosage (1-10 ml l-1), revealed that the degradation rate is strongly influenced by respective experimental parameters. However the influence of catalyst alone is not predominant in degradation. The decolorization of dye proceed to near completeness when H2O2 is used. The best degradation results are observed at 0.1 wt% of catalyst loading at pH 2 for TiO2/UV system. It has been found that the optimum concentration of H2O2 for 12 ppm and 20 ppm amount of the dye was 2ml l-1 for UV/H2O2 system. The kinetic of degradation of the dye followed the pseudo first order rate. The degradation studies using TiO2/UV/H2O2 system, indicates enhancement in the degradation rate of the dye compared to that of UV/H2O2 system alone.
ABSTRACT
Hepatotoxicity in two drug regimens was studied at Central Leprosy Teaching and Research Institute, Chengalpattu (Tamil Nadu) during 1983-84. In 'P' regimen-prothionamide 350 mg daily, dapsone 100 mg daily and rifampicin 600 mg at monthly intervals were given. In' C' regimen-dapsone 100 mg daily, rifampicin 600 mg once a month and clofazimine 300 mg once a month and 100 mg alternate day were given. Trial was started with fifty multibacillary adult leprosy patients in each group. Enzymatic hepatic dysfunction was noted in 52-58 per cent of the cases even before the therapy was started. In 'P' regimen, four cases of clinical jaundice and six cases of high bilirubinaemia was noticed during the trial as against two cases each of clinical jaundice and high bilirubinaemia in 'C regimen. Of the two cases of clinical jaundice in 'C' regimen, one turned out to be a case of HBV infection. The study which is in progress, indicated higher hepatotoxicity in 'P' regimen which is probably explained by the simultaneous use of two hepatotoxic drugs. Viral hepatitis is endemic in this area and might have aggravated the hepatotoxicity observed.

The present experiment was planned to assess the role of vagus and adrenals in gastric secretion in the pylorus ligated rats. Vagotomy significantly reduced the volume of gastric juice but the reduction following adrenalectomy was not significant. Both vagotomy and adrenalectomy significantly reduced the free acid, total acid and pepsin contents of the gastric secretion, the reduction being more pronounced following vagotomy.
