Hepatocellular carcinoma with extension to the diaphragm, falciform ligament, rectus abdominis and paraumbilical vein

Hepatocellular carcinoma is the most common primary tumour of the liver. The most common extrahepatic metastatic sites are the lung, lymph nodes, bones and adrenal glands. All forms of HCC demonstrate a tendency for vascular invasion, producing extensive intrahepatic metastases and, occasionally, portal vein or inferior vena cava extension with spread into the right atrium in extreme cases. Tumour spread of abdominal diseases via hepatic ligaments has also been previously reported. We report a rare case of hepatocellular carcinoma with extension into the falciform ligament, overlying rectus sheath and adjacent diaphragm with concomitant infiltration into the recanalised paraumbilical vein

Nature of Intra-night Optical Variability of BL Lacertae

We present the results of extensive multi-band intra-night optical monitoring of BL Lacertae during 2010--2012. BL Lacertae was very active in this period and showed intense variability in almost all wavelengths. We extensively observed it for a total for 38 nights; on 26 of them observations were done quasi-simultaneously in B, V, R and I bands (totaling 113 light curves), with an average sampling interval of around 8 minutes. BL Lacertae showed significant variations on hour-like timescales in a total of 19 nights in different optical bands. We did not find any evidence for periodicities or characteristic variability time-scales in the light curves. The intranight variability amplitude is generally greater at higher frequencies and decreases as the source flux increases. We found spectral variations in BL Lacertae in the sense that the optical spectrum becomes flatter as the flux increases but in several flaring states deviates from the linear trend suggesting different jet components contributing to the emission at different times.Comment: 12 Pages, 5 figures, 3 Tables, Accepted for Publication in MNRA

Short-Term, Intermittent Fasting Induces Long-Lasting Gut Health and TOR-Independent Lifespan Extension

Intermittent fasting (IF) can improve function and health during aging in laboratory model organisms, but the mechanisms at work await elucidation. We subjected fruit flies (Drosophila melanogaster) to varying degrees of IF and found that just one month of a 2-day fed:5-day fasted IF regime at the beginning of adulthood was sufficient to extend lifespan. This long-lasting, beneficial effect of early IF was not due to reduced fecundity. Starvation resistance and resistance to oxidative and xenobiotic stress were increased after IF. Early-life IF also led to higher lipid content in 60-day-old flies, a potential explanation for increased longevity. Guts of flies 40 days post-IF showed a significant reduction in age-related pathologies and improved gut barrier function. Improved gut health was also associated with reduced relative bacterial abundance. Early IF thus induced profound long-term changes. Pharmacological and genetic epistasis analysis showed that IF acted independently of the TOR pathway because rapamycin and IF acted additively to extend lifespan, and global expression of a constitutively active S6K did not attenuate the IF-induced lifespan extension. We conclude that short-term IF during early life can induce long-lasting beneficial effects, with robust increase in lifespan in a TOR-independent manner, probably at least in part by preserving gut health

CASE REPORT Abdominal Subcutaneous Fat Aspiration – An Alternative Method to Diagnose Amyloidosis

A middle aged lady presented with clinical manifestations of primary amyloidosis which included amyloid cardiomyopathy. There was failure to confirm the diagnosis of amyloidosis with biopsies from rectal and tongue tissues. Fat tissue obtained from abdominal subcutaneous fat aspiration eventually demonstrated the presence of amyloid
