Capsaicin(trans-8-methyl-N-vanillyl-6-nonenamide) is the main component in hot peppers, including red chili peppers, alapenos, and habanero, belonging to the genus Capsicum. Capsaicin is a potent antioxidant that interferes with free radical activities. In the present study, the possible protective effect of capsaicin was studied against methyl methanesulphonate(MMS) induced toxicity in third instar larvae of transgenic Drosophila melanogaster(hsp70-lacZ)Bg^9. The third instar was allowed to feed on the diet having different doses of capsaicin and MMS separately and in combination. The results suggested that the exposure of third instar larvae to the diet having MMS alone showed significant hsp70 expression as well as tissue DNA and oxidative damage, whereas the larvae feed on the diet having MMS and capsaicin showed a decrease in the toxic effects for 48-h of exposure. In conclusion, capsaicin showed a dose-dependent decrease in the toxic effects induced by MMS in the third instar larvae of transgenic Drosophila melanogaster.

Objectives: To report rare metastasis in breast from rectal cancer. Case Report: A 47-year-old married lady who presented with rectal bleeding for six weeks and diagnosed as a case of adenocarcinoma with no metastasis underwent neoadjuvent radiotherapy and chemotherapy and then abdominoperineal resection on follow-up found to have left breast mass and skin lesion in upper abdominal wall. Mammogram showed BIRADS-5. Tru cut biopsy showed mucinous/signet ring adenocarcinoma and she underwent lumpectomy and sentinel lymph node biopsy and excision of skin lesion. Histopathology of breast lump and skin lesion came as mucinous adeno-carcinoma of colonic origin, but all axillary lymph nodes were negative for malignancy. Conclusion: Metastatic breast lump is rare entity and every effort to be put to diagnose it using modern diagnostic tools.

Use of X-ray contrast allows us to differentiate between two or more adjacent structures on radiographic studies. The X-ray contrast agent can be the one with increase X-ray absorption, like iodine and a barium X-ray contrast agent or the one with decrease X-ray absorption like air and carbon dioxide contrast agent. Each contrast agent possesses different risks and benefits in various ways. Carbon dioxide as an intravascular contrast agent can be used as an alternative intravascular contrast agent and has superior results in some cases. In patients with renal dysfunction or iodinated contrast allergy, the use of Iodinated Contrast Agent poses the risk of considerable morbidity. Similarly, use of Gadolinium is discouraged in subject with severe renal dysfunction. Use of carbon dioxide(CO_2) as an intravascular contrast, offers an alternative in such patients for certain procedures, as it is not nephrotoxic and it does not incite allergic reactions. It is inexpensive, readily available and due to its unique physical properties, it can be used to image a wide variety of vascular beds and chambers. The aim of this paper is to systemically review the current literature to describe the indications, contraindications, adverse effects, instruments, precautions, latest methodologies and data supporting for the use of CO_2 as a contrast agent.

Aluminum matrix composites(AMCs), reinforced with novel pre-synthesized Al/Cu Fe multi-layered coreshell particles, were fabricated by different consolidation techniques to investigate their effect on microstructure and mechanical properties. To synthesize multi-layered Al/Cu Fe core-shell particles, Cu and Fe layers were deposited on Al powder particles by galvanic replacement and electroless plating method, respectively. The core-shell powder and sintered compacts were characterized by using X-ray diffraction(XRD), scanning electron microscopy(SEM) equipped with energy dispersive spectroscopy(EDX), pycnometer, microhardness and compression tests. The results revealed that a higher extent of interfacial reactions, due to the transformation of the deposited layer into intermetallic phases in spark plasma sintered composite, resulted in high relative density(99.26%), microhardness(165 HV0.3) and strength(572 MPa). Further, the presence of un-transformed Cu in the shell structure of hot-pressed composite resulted in the highest fracture strain(20.4%). The obtained results provide stronger implications for tailoring the microstructure of AMCs through selecting appropriate sintering paths to control mechanical properties.

The present study was carried out during the year 2013-14 on the screening of the selected linseed genotypes for yield performance in Sindh, Pakistan. The experiment was laid out at the experimental fields of Oilseeds Section, Agriculture Research Institute, Tandojam in a three replicated randomized complete block design. Twelve linseed genotypes (L-53, C-W-2, Shikarpur 2, P-16-4, L-8, 11-106, Hala 3, L-17, Santane, Summit, L-10 and check llsi 90) were screened for their agronomic performance and correlations amongst yield and its contributing traits were calculated. The analysis of variance suggested significant (P -16-4 surpassed Ilsi-90 for primary branches;and most of the remaining genotypes were at par with the commercial check for primary branches. Genotype L-10 surpassed the commercial check for capsules plant-1 and L-8 was at par with the commercial check;while none of the genotypes could surpass commercial check variety for seed index, but 11-106, Hala-3 and Summit also showed promising performance regarding the seed index. All the genotypes tested in this experiment such as L-53, C-W-2, Shikarpur 2, P-16-4, L-8, 11-106, Hala 3, L-17, Santane, Summit, L-10 surpassed the commercial check variety Ilsi-90 for seed yield plot-1. The correlation coefficient for yield and its contributing traits of linseed genotypes showed a positive and significant (P -1 vs seed yield plant-1 (r = 0.3334*), days to maturity vs spike length (r = 0.5384**), days to 75% flowering vs days to 90% maturity (r = 0.4073**), days to 75% flowering vs seed index (r = 0.429
