Regional fat loss from the thigh in obese women after adrenergic modulation

Beta-adrenergic stimulation and alpha 2-adrenergic inhibition increase lipolysis from fat cells. Twenty-eight obese women were placed on a calorie-restricted diet and one of five treatments was applied to one thigh three to five times per week for four weeks: (1) isoproterenol injections; (2) cream containing colforsin (forskolin), aminophylline, and yohimbine; (3) yohimbine cream; (4) colforsin cream; or (5) aminophylline cream. The opposite thigh was treated with a placebo (injection or cream). The treated thighs lost significantly more girth after treatment, both by injection and by cream. No adverse reactions were attributable to either the cream or the injections. It is concluded that local fat reduction from the thigh can be safely accomplished.     

A new calicivirus isolated from a marine mammal

Summary A new serotype of calicivirus, designated as San Miguel sea lion virus type 6 (SMSV-6), was isolated from vesicular lesions on the flipper of a California sea lion pup. Serologic studies show that SMSV-6 neutralizing antibodies (SN) occur frequently among California sea lions and occasionally among northern fur seals. Feral swine, 1- to 6-week elephant seal pups and grey whales tested negative for SMSV-6 antibody.     

Fc receptor-bearing peripheral blood mononuclear cells in breast cancer patients: a possible marker of tumour burden and prognosis.

Indirect immunofluorescence was used to identify and quantitate peripheral blood mononuclear (PBM) cells possessing high avidity Fc receptors in 105 patients upon referral to the breast cancer clinic at the Cross Cancer Institute. The cell detected was shown to be a non-adherent PBM, probably belonging to the T or null cell population. The mean percentage +/- 2 standard deviations of PBM-positive cells in 75 patients with no disease or benign breast disease was 5.3 +/- ;6.7, and this was significantly (P less than 0.001) less than the percentage found for 31 patients with breast cancer. The percentage of PBM-positive cells correlated directly with tumour burden in patient with small (less than or equal to 5 cm) tumours without regional node or extranodal metastases (5/13 had greater than or equal to 12% positive PBM) and in those with small tumours plus regional node metastases, but without extranodal metastases (8/10 had greater than or equal to 12% positive PBM). This correlation was less, however, in patients with large tumours (greater than 5 cm), and in those with extranodal metastases (4/8 had greater than or equal to 12% positive PBM), and in patients tested postoperatively (1/13 had greater than or equal to 12% positive PBM) even though 6!13 had regional node metastases at the time of surgery. Thus, this relatively simple assay, which can be done on peripheral blood samples, may turn out to be useful in patients with breast cancer as a prognostic marker insofar as it may be an indirect indicator of tumour burden preoperatively. If so, it may lead to a more aggressive postoperative adjuvant therapy approach to the subpopulation of node-negative PBM-positive breast cancer patients than is currently used for node-negative patients.     

Does hope predict adjustment to end‐stage renal failure and consequent dialysis?

Objectives Hope is important in determining positive outcomes in a range of chronic illnesses. This study examined the role of hope in adjustment to end‐stage renal failure (ESRF) and consequent dialysis. Design A cross‐sectional design examined the ability of hope to predict adjustment to ESRF over and above other relevant variables. Methods Individuals receiving dialysis at 4 units in the North‐West UK were invited to take part in the study. 103 questionnaire packs were included in the analysis. Multiple regression equations determined whether hope was able to predict significant variance in adjustment over and above that accounted for by other factors (demographic and illness‐related factors, perceived control, and social support). Measures of anxiety, depression, and quality of life constituted a multidimensional measure of adjustment to ESRF. Results Each of the regression models was significant. Hope emerged as an independent significant predictor in five of the multiple regressions: anxiety; depression; effects and symptoms of kidney disease; and mental health quality of life. Age also emerged as an important predictor of outcome. Conclusions It appears that hope is a significant predictor of adjustment to ESRF. Clinical implications of this research are discussed, along with suggestions for future research.     

Enterostatin (Val-Pro-Asp-Pro-Arg), the activation peptide of procolipase, selectively reduces fat intake

Valine-proline-aspartate-proline-arginine (VPDPR), the amino terminal pentapeptide of pancreatic procolipase, produced a dose-dependent reduction in food intake when injected intraperitoneally into Osborne-Mendel rats that had been starved overnight. This inhibition of feeding was observed when the rats were fed a high-fat diet but not in rats fed a high-carbohydrate, low-fat diet. At higher doses of VPDPR, the inhibition of feeding was maintained for over 6 hours. An equimolar mixture of the free amino acids had no effect on food intake. In rats adapted to a three-choice macronutrient diet, VPDPR inhibited fat intake but had no effect on carbohydrate or protein intake. This selective inhibition of fat intake was observed in both overnight-fasted rats presented with food and in ad-lib-fed rats at the beginning of the dark-onset feeding period. It is suggested that this peptide may be a feedback signal to regulate the intake of dietary fat.     

Depression,anxiety, and loneliness among adolescents and young adults with IBD in the UK: the role of disease severity,age of onset,and embarrassment of the condition

A new species of Stephanostomum Looss, 1899 (Digenea, Acanthocolpidae) with a bizarre oral sucker: S. adlardi sp. nov. from the common coral trout Plectropomus leopardus (Lacepède, 1802) (Perciformes, Serranidae) from Lizard Island, Great Barrier Reef

A new species of Acanthocolpidae, Stephanostomum adlardi is described from the serranid Plectropomus leopardus from Lizard Island in the northern Great Barrier Reef. It differs from all previously described acanthocolpids in the structure of the oral sucker which is extended into dorsal and ventral lobes each bearing a row of spines. A phylogenetic tree estimated from combined nuclear small and partial large ribosomal RNA gene sequences shows that, despite the unusual oral sucker structure, the species is a true member of the genus Stephanostomum. The molecular results also suggest that Monostephanostomum nolani is derived from within Stephanostomum.
