Galis I, Simek P, Macas J, Zahradnickova H, Vlasak J, Wabiko H, Van Dongen W, Van Onckelen HA, Ondrej M.
PMID: 10550626
Planta. 1999 Oct;209(4):453-61. doi: 10.1007/s004250050748.

The 6b gene of Agrobacterium tumefaciens has been demonstrated to modify the activity of the plant growth regulators, auxin and cytokinin. To study the possible mode of action of the gene, tobacco (Nicotiana tabacum L. cv. Samsun) plants were...

Clostridial neurotoxins: new tools for dissecting exocytosis.

Trends in cell biology

Niemann H, Blasi J, Jahn R.
PMID: 14731646
Trends Cell Biol. 1994 May;4(5):179-85. doi: 10.1016/0962-8924(94)90203-8.

Tetanus toxin and botulinal toxins are potent inhibitors of neuronal exocytosis. Within the past five years the protein sequences of all eight neurotoxins have been determined, their mode of action as metalloproteases has been established, and their intraneuronal targets...

A connectionist model for category perception: theory and implementation.

IEEE transactions on neural networks

Basak J, Murthy CA, Chaudhury S, Majumder DD.
PMID: 18267725
IEEE Trans Neural Netw. 1993;4(2):257-69. doi: 10.1109/72.207613.

A connectionist model for learning and recognizing objects (or object classes) is presented. The learning and recognition system uses confidence values for the presence of a feature. The network can recognize multiple objects simultaneously when the corresponding overlapped feature...

Hough transform network: learning conoidal structures in a connectionist framework.

IEEE transactions on neural networks

Basak J, Das A.
PMID: 18244439
IEEE Trans Neural Netw. 2002;13(2):381-92. doi: 10.1109/72.991423.

A two-layer neural-network model is designed which accepts image coordinates as the input and learns the parametric form of conoidal shapes (lines/circles/ellipses) adaptively. It provides an efficient representation of visual information embedded in the connection weights and the parameters...

Blind separation of uniformly distributed signals: a general approach.

IEEE transactions on neural networks

Basak J, Amari S.
PMID: 18252618
IEEE Trans Neural Netw. 1999;10(5):1173-85. doi: 10.1109/72.788656.

A general algorithm for blind separation of uniformly distributed signals is presented. First maximum likelihood equations are obtained for dealing with this task. It is difficult to obtain a closed form maximum likelihood solution for arbitrary mixing matrix. The...

Melatonin levels in serum and ascitic fluid of patients with hepatic encephalopathy.

Gastroenterology research and practice

Chojnacki C, Romanowski M, Winczyk K, Błasiak J, Chojnacki J.
PMID: 23346104
Gastroenterol Res Pract. 2012;2012:510764. doi: 10.1155/2012/510764. Epub 2012 Dec 30.

Cirrhotic patients exhibit disturbed melatonin homeostasis, which may lead to sleep disturbances, but an influence on the hepatic encephalopathy has not been elucidated. Aim. In the present study, the association of melatonin levels in serum and ascitic fluid and...

Drug Delivery Systems for Vitamin D Supplementation and Therapy.

Pharmaceutics

Glowka E, Stasiak J, Lulek J.
PMID: 31323777
Pharmaceutics. 2019 Jul 18;11(7). doi: 10.3390/pharmaceutics11070347.

Vitamin D (VD) is a fat-soluble prohormone well known for its role in regulating calcium and phosphate metabolism. It has been clinically used for many years to prevent rickets in children, osteomalacia, and osteoporosis in adults. VD insufficiency is...

A survey of prevalence of narrative and systematic reviews in five major medical journals.

BMC medical research methodology

Faggion CM, Bakas NP, Wasiak J.
PMID: 29281975
BMC Med Res Methodol. 2017 Dec 28;17(1):176. doi: 10.1186/s12874-017-0453-y.

BACKGROUND: Systematic reviews may provide less biased evidence than narrative reviews because they observe a strict methodology, similarly to primary studies. Hence, for clinical research questions, systematic reviews should be the study design of choice. It would be important...

MATERIAL AND METHODS: Ninety subjects (aged 35-49 years) were enrolled in the study and separated into 3 groups of 30 subjects each. Group I - healthy volunteers without RESULTS: The expression of this enzyme in antral mucosa was 2.69...

Biomolecular computers with multiple restriction enzymes.

Genetics and molecular biology

Sakowski S, Krasinski T, Waldmajer J, Sarnik J, Blasiak J, Poplawski T.
