Psychological Support for Cancer Patients.

From the time a person is diagnosed with cancer, a psychological sequalae of intense emotional challenges emerge for the patient as well as family members. Different stages require different types of psychosocial support including those for previvors, survivors, and people who need palliative care. Currently, there is an emphasis on not only providing psychological assistance to cope with emotional, interpersonal, and economic stresses, but training programs specially designed to activate personal and social resources to find happiness and meaning in adversity. Within this perspective, the chapter is divided into three sections, each considering the common mental health issues and positive changes and intervention and therapies for cancer patients, family members, caregivers, onco-staff, and professionals.

Fungal mediated biotransformation of melengestrol acetate, and T-cell proliferation inhibitory activity of biotransformed compounds.

Glomerella fusaroide, and Rhizopus stolonifer were effectively able to transform the steroidal hormone melengestrol acetate (MGA) (1) into four (4) new metabolites, 17α-acetoxy-11α-hydroxy-6-methyl-16-methylenepregna-4,6-diene-3,20-dione (2), 17α-acetoxy-11α-hydroxy-6-methyl-16-methylenepregna-1,4,6-triene-3,20-dione (3), 17α-acetoxy-6,7α-epoxy-6ß-methyl-16-methylenepregna-4,6-diene-3,20-dione (4), and 17α-acetoxy-11ß,15ß-dihydroxy-6-methyl-16-methylenepregna-4,6-diene-3,20-dione (5). All these compounds were structurally characterized by different spectroscopic techniques. The objective of the current study was to assess the anti-inflammatory potential of melengestrol acetate (1), and its metabolites 2-5. The metabolites and the substrate were assessed for their inhibitory effects on proliferation of T-cells in vitro. The substrate (IC50 = 2.77 ± 0.08 µM) and its metabolites 2 (IC50 = 2.78 ± 0.07 µM), 4 (IC50 = 2.74 ± 0.1 µM), and 5 (IC50 = < 2 µM) exhibited potent T- cell proliferation inhibitory activities, while compound 3 (IC50 = 29.9 ± 0.09 µM) showed a moderate activity in comparison to the standard prednisolone (IC50 = 9.73 ± 0.08 µM). All the metabolites were found to be non-toxic against 3T3 normal cell line. This study thus identifies some potent compounds active against T-cell proliferation. Their anti-inflammatory potential, therefore, deserves to be further investigated.

Bacterial lipases: A review on purification and characterization.

Lipase (E.C.3.1.1.3) belongs to the hydrolases and is also known as fat splitting, glycerol ester hydrolase or triacylglycerol acylhydrolase. Lipase catalyzes the hydrolysis of triglycerides converting them to glycerol and fatty acids in an oil-water interface. These are widely used in food, dairy, flavor, pharmaceuticals, biofuels, leather, cosmetics, detergent, and chemical industries. Lipases are of plant, animal, and microbial origin, but microbial lipases are produced at industrial level and represent the most widely used class of enzymes in biotechnological applications and organic chemistry. Phylogenetic analysis and comparison of residues around GxSxG motif provided an insight to the diversity among bacterial lipases. A variety of para-Nitrophenyl (p-NP) esters having C2 to C16 (p-NP acetate to p-NP palmitate) in their fatty acid side chain can be hydrolyzed by bacterial lipases. Large heterogeneity has been observed in molecular and catalytic characteristics of lipases including molecular mass; 19-96 kDa, Km; 0.0064-16.58 mM, Kcat; 0.1665-1.0 × 104 s-1 and Kcat/Km; 26.02-7377 s-1/mM. Optimal conditions of their working temperature and pH have been stated 15-70 °C and 5.0-10.8, respectively and are strongly associated with the type and growth conditions of bacteria. Surface hydrophobicity, enzyme activity, stability in organic solvents and at high temperature, proteolytic resistance and substrate tolerance are the properties of bacterial lipases that have been improved by engineering. Bacterial lipases have been extensively studied during last decade. However, their wider applications demand a detailed review on purification, catalytic characterization and applications of lipases.

Role of Sociocultural Factors in Depression among Elderly of Twin Cities (Rawalpindi and Islamabad) of Pakistan.

This research was conducted to examine the role of sociocultural factors on depression among elderly of twin cities (Rawalpindi and Islamabad) of Pakistan. 310 older adults participated in the present study. Through convenient sampling technique, face to face interview was carried out for data collection. Urdu translated Geriatric Depression Scale Short Form and demographic sheet were used to test hypotheses. Descriptive statistics and t-test were used for data analysis. Results showed significant mean differences among gender, marital status, family system, and status of employment on depression. Financial crisis, feeling of dejection because of isolation, and trend of nuclear family system have been observed as strong predictors of depression in older adults.
