Improvement of muscle strength in specific muscular regions in nusinersen-treated adult patients with 5q-spinal muscular atrophy.

Real-world data have shown mild improvement of overall motor function in adult patients treated with nusinersen, the first approved therapy for 5q-spinal muscular atrophy (SMA). However, knowledge about preferably targeted muscle functions is sparse. The aim of this study was to evaluate strength of distinct muscles and body regions in adult SMA patients in the early course of nusinersen therapy.

Validity and reliability of the German multidimensional fatigue inventory in spinal muscular atrophy.

Objective: Fatigue is a common and burdensome symptom of spinal muscular atrophy. Given its complex interactions, different dimensions of fatigue need to be investigated. The Multidimensional Fatigue Inventory is a widely used instrument that captures five distinct dimensions.

Cognitive Performance of Patients with Adult 5q-Spinal Muscular Atrophy and with Amyotrophic Lateral Sclerosis.

Motor neuron diseases, such as spinal muscular atrophy (SMA) and amyotrophic lateral sclerosis (ALS), share several clinical similarities while differing substantially in etiology, disease onset and progression. Cognitive dysfunction, a clinically relevant non-motor feature in a substantial proportion of ALS patients, has been less frequently investigated in SMA. In this prospective multicenter cross-sectional study, cognitive function was assessed by the Edinburgh Cognitive (and Behavioural) ALS Screen (ECAS) and a German vocabulary test (Wortschatztest, WST) in 34 adult patients with SMA types 2-4 and in 34 patients with ALS.

An observational cohort study on impact, dimensions and outcome of perceived fatigue in adult 5q-spinal muscular atrophy patients receiving nusinersen treatment.

Background: Efficacy of nusinersen in adult 5q-spinal muscular atrophy (SMA) patients regarding motor function has recently been demonstrated. However, additional outcome measures are needed to capture non-motor improvements. Fatigue is a common and disabling symptom in neurologic diseases, but little is known about its frequency, characteristics and associated factors in SMA.

The type 2 acyl-CoA:diacylglycerol acyltransferase family of the oleaginous microalga Lobosphaera incisa.

Background: Oleaginous microalgae are promising sources of energy-rich triacylglycerols (TAGs) for direct use for food, feed and industrial applications. Lobosphaera incisa is a fresh water unicellular alga, which in response to nutrient stress accumulates a high amount of TAGs with a high proportion of arachidonic acid (ARA). The final committed step of de novo TAG biosynthesis is catalyzed by acyl-CoA:diacylglycerol acyltransferases (DGATs), which add a fatty acid (FA) to the final sn-3 position of diacylglycerol (DAG).

Analysis of the lipid body proteome of the oleaginous alga Lobosphaera incisa.

Background: Lobosphaera incisa (L. incisa) is an oleaginous microalga that stores triacylglycerol (TAG) rich in arachidonic acid in lipid bodies (LBs). This organelle is gaining attention in algal research, since evidence is accumulating that proteins attached to its surface fulfill important functions in TAG storage and metabolism.

Full establishment of arbuscular mycorrhizal symbiosis in rice occurs independently of enzymatic jasmonate biosynthesis.

Development of the mutualistic arbuscular mycorrhiza (AM) symbiosis between most land plants and fungi of the Glomeromycota is regulated by phytohormones. The role of jasmonate (JA) in AM colonization has been investigated in the dicotyledons Medicago truncatula, tomato and Nicotiana attenuata and contradicting results have been obtained with respect to a neutral, promotive or inhibitory effect of JA on AM colonization. Furthermore, it is currently unknown whether JA plays a role in AM colonization of monocotyledonous roots.

The half-size ABC transporters STR1 and STR2 are indispensable for mycorrhizal arbuscule formation in rice.

The central structure of the symbiotic association between plants and arbuscular mycorrhizal (AM) fungi is the fungal arbuscule that delivers minerals to the plant. Our earlier transcriptome analyses identified two half-size ABCG transporters that displayed enhanced mRNA levels in mycorrhizal roots. We now show specific transcript accumulation in arbusculated cells of both genes during symbiosis.

Personality factors differentially predict exercise behavior in men and women.

Personality assessed with the Minnesota Multiphasic Personality Inventory (MMPI) in college was used to predict exercise behavior measured at midlife in 3,630 men and 796 women enrolled in the University of North Carolina Alumni Heart Study. Logistic regression models were fitted for each of the MMPI clinical scales to test the predictive effect of personality, gender, and their interaction on adult exercise behavior. Lower depression, social introversion, and psychopathic deviance scores were associated with increased probability of exercising in midlife for both men and women.

A panel of antibodies useful in the cytologic diagnosis of metastatic melanoma.

Five antibodies, 2D.1 (pan-leukocyte), AE-1,3 (anti-keratin), B72.3 (anti-carcinoma), ME 1-14 (alpha-chondroitin sulfate proteoglycan) and polyclonal S-100 protein (P-S100), were tested to determine if this panel could be used immunocytochemically to differentiate melanoma from nonmelanoma.

Cell dissociation techniques in human breast cancer--variations in tumor cell viability and DNA ploidy.

Approximately 70% of breast cancers contain cell populations with hyperdiploid (greater than G0/G1) DNA content; however, cells cultured from breast cancers have only diploid DNA contents and karyotypes. Mechanically dissociated cells rarely, if ever, grow in culture, while enzymatically dissociated cells do grow in most cases. To determine if cell dissociation techniques used to prepare cells for culture and other laboratory procedures select for cells with specific features, and if tumor cells are killed in the process, breast cancer cells obtained by mechanical dissociation and by enzymatic dissociation were examined for DNA content and cell viability (measured by dye exclusion).

A phase I/II SECSG (Southeastern Cancer Study Group) pilot study of surgical adjuvant immunotherapy with vaccinia melanoma oncolysates (VMO).

Forty-eight patients with nonrecurrent high risk Stage I and II malignant melanoma were treated with Vaccinia Melanoma Oncolysates (VMO). Six different dose levels and two different treatment regimens were tested. Thirty-two out of 48 patients completed the 12 months of therapy.

Clinical response to hormone therapy correlated with estrogen receptor analyses. Biochemical v histochemical methods.

Estrogen receptor (ER) analysis by sucrose density gradient analysis (SDGA) was compared with histochemical localization of estrogen binding using 6-carbomethoxy-bovine serum albumin-fluorescein isothiocyanode-estradiol (E2-6-CMO-BSA-FITC) (6FE), 17-thiosemicarbozene-BSA-FITC-estrogen (E-17-TSC-BSA-FITC) (17FE), and polyestradiol phosphate-antiestradiol antibody-FITC (PEP) on serial frozen sections of metastatic breast cancer lesions from 72 patients treated with hormonal therapy. A comparison of assays to clinical responses gave the following sensitivities: ER-SDGA, 90%; 6FE, 50%; 17FE, 55%; and PEP, 58%. Specificities were as follows: ER-SDGA, 81%; 6FE, 47%; 17FE, 41%; and PEP, 59%.
