A prospective one year study on groups of 377 high risk individuals was done using alphafoetoprotein (AFP), alpha 1antitrypsin (A1AT), alpha 1-acidglycoprotein 1 (A1GP), gammaglutamyltraspeptidase (GGT) and isocitrate dehydrogenase (ICD) to detect hepatocellular carcinoma (HCC). The high risk groups screened were: cirrhosis, unexplanable hepatomegalies, chronic hepatitis B surface antigen (HBsAg) carrier, family members of afflicted HCC cases, individuals on hormonal therapy and males over the age of 30 years. 58/377 (15%) were found to have HCC. This consisted of 16/43 (37%) clinical cirrhosis, 40/71 (56%) unexplanable hepatomegalies, 1/33 (3%) chronic HBsAg, 1/156 (0.6%) family members. AFP remained the most useful test but the others such as A1AT, A1Gp, GGT and ICD recognised both malignant and asymptomatic nonmalignant diseases. Only 4 (7%) patients had resectible tumours detected and 1 patient was found to have liver dysplasia. HBsAg positivity and persistently raised AFP. The significance of HBsAg amongst family members and other group is discussed in terms of genetic susceptibility, environmental oncogenic vulnerability and ultimate screening.

The catabolic pathways and cellular responses of Pseudomonas putida P8 during growth on benzoate were studied through proteomics approach. Two-dimensional gel electrophoresis (2-DE) gel profiles of P. putida cells grown on 100 and 800 mg/L benzoate were quantitatively compared using threshold criteria and statistical tools. Protein spots of interest were identified through database searching based on peptide mass fingerprints (PMFs) obtained using matrix assisted laser desorption/ionization-time of flight mass spectrometry (MALDI-TOF MS). Eight catabolic enzymes involved in both the ortho-cleavage (CatB, PcaI, and PcaF) and the meta-cleavage (DmpC, DmpD, DmpE, DmpF, and DmpG) pathways for benzoate biodegradation were identified in P. putida grown on 800 mg/L of benzoate while no meta-cleavage pathway enzymes were observed in the 2-DE gel profiles of P. putida grown on 100 mg/L of benzoate. The activation of both the ortho- and the meta-cleavage pathways in P. putida P8 grown on high benzoate concentration was confirmed directly at the protein level. In addition, another 28 differentially expressed proteins were also identified, including proteins involved in (i) detoxification and stress response (AhpC, ATPase-like ATP-binding region, putative DNA-binding stress protein, SodB and catalase/peroxidase HPI); (ii) carbohydrate, amino acid/protein and energy metabolism (isocitrate dehydrogenase, SucC, SucD, AcnB, GabD, ArcA, ArgI, Efp and periplasmic binding proteins of several ABC-transporters); and (iii) cell envelope and cell division (bacterial surface antigen family protein and MinD). Based on the data obtained, physiological changes of P. putida in response to growth on benzoate at different concentrations were discussed.
