Epidermal ceramides (Cer) comprise a heterogeneous family of seven species, including two unique omega-hydroxylated Cer, that are key components of the stratum corneum (SC) intercellular lamellar membranes responsible for the epidermal permeability barrier. Although both glucosylceramide (GlcCer) and the phospho-sphingolipid sphingomyelin (SM) are potential precursors of SC Cer, based on report...

Spliceosomal small nuclear ribonucleoproteins (snRNPs) in trypanosomes contain either the canonical heptameric Sm ring or variant Sm cores with snRNA-specific Sm subunits. Here we show biochemically by a combination of RNase H cleavage and tandem affinity purification that the U4 snRNP contains a variant Sm heteroheptamer core in which only SmD3 is replaced by SSm4. This U4-specific, nuclear-lo...

It is known that sphingomyelin (SM) content is higher in apolipoprotein B-containing particles (BLps) than in high density lipoproteins and that BLp levels, including chylomicrons and their remnant particles, are positively related to atherosclerosis. To evaluate the relationship between serum SM and postprandial remnant particle levels, we determined SM, triglyceride (TG), and cholesterol leve...

Second malignancies (SM) represent one of the potential hazards of modern cancer treatment and especially of radio- and chemotherapy after surgery for breast cancer. For this reason, regional tumor registry data (1960-1975) on 1985 breast cancer patients were analyzed for SM in the retrospective part of our study. These data were compared with the prospective part of the study in which 241 pati...

BACKGROUND Malnutrition, weight loss, and muscle wasting (sarcopenia) are common among women with advanced ovarian cancer and have been associated with adverse clinical outcomes and survival. Our objective is to investigate overall survival (OS) related to changes in skeletal muscle (SM) for patients with advanced ovarian cancer treated with neoadjuvant chemotherapy and interval debulking. ME...

Schistosomes express a family of integral membrane proteins, called tetraspanins (TSPs), in the outer surface membranes of the tegument. Two of these tetraspanins, Sm-TSP-1 and Sm-TSP-2, confer protection as vaccines in mice, and individuals who are naturally resistant to S. mansoni infection mount a strong IgG response to Sm-TSP-2. To determine their functions in the tegument of S. mansoni we ...

A previous study suggested that the long-acting beta2-adrenergic agonist salmeterol (SM) had inhibitory effects on bronchial mucosal inflammation 6 hours after allergen exposure. To further evaluate the influence of SM on allergen-induced airway inflammation. We studied, in a randomized, double-blind, cross-over trial, 16 mild asthmatic patients who had a dual asthmatic response to allergen inh...

Mammalian phosphatidylinositol transfer proteins (PITPs) alpha and beta, which share 77% identity, have been shown to exhibit distinct lipid-transfer activities. In addition to transferring phosphatidylinositol (PI) and phosphatidylcholine (PC), PITPbeta has been shown to transfer sphingomyelin (SM), and this has led to the suggestion that PITPbeta is important for the regulation of SM metaboli...

OBJECTIVES To determine sex differences in the distribution of regional and total skeletal muscle (SM) using contiguous whole body magnetic resonance imaging (MRI) data, and to examine the relations between fat free mass (FFM) and total and regional SM masses. METHODS A total of 20 Japanese college students (10 women and 10 men) volunteered for the study. FFM was measured by two compartment d...

Sir: Inactivation of aminoglycoside antibiotics in clinical isolates has been studied by many research workers". Streptomycin(SM)-inactivating enzymes were reported to exist in SM-resistant strains of Staphylococcus auren.s2-11, Escherichia coli l',, and Pseudomonas aeruginosal 1-11), in which are operative 2 mechanisms, phosphorylation and adenylylation, i.e., SM 3"-phosphotransferase; APH(3")...
