A series of half-sandwich and sandwich-type lanthanide(III) complexes have been prepared using tetrabenzotriazaporphyrin ligands. Reaction of 27-phenyl-29H,31H-tetrabenzo[b,g,l,q][5,10,15]-triazaporphyrin (PhTBTAPH2, 1) with salts [LnX3]·nH2O (Ln = Eu (a), Lu (b); X = OAc, acac) afforded the single- and homoleptic double-deckers (PhTBTAP)LnOAc...

Cell-generated forces play a foundational role in tissue dynamics and homeostasis and are critically important in several biological processes, including cell migration, wound healing, morphogenesis, and cancer metastasis. Quantifying such forces

Transformation and outcome of nodular lymphocyte predominant Hodgkin lymphoma: a Finnish Nationwide population-based study.

Blood cancer journal

Kalashnikov I, Tanskanen T, Pitkäniemi J, Malila N, Jyrkkiö S, Leppä S.
PMID: 34923571
Blood Cancer J. 2021 Dec 18;11(12):203. doi: 10.1038/s41408-021-00586-1.

Nodular lymphocyte predominant Hodgkin lymphoma (NLPHL) is a rare B-cell malignancy associated with excellent survival. However, some patients experience histological transformation into aggressive large B-cell lymphoma. Population-based data on transformation in patients with NLPHL is limited. We conducted a...

Second harmonic generation in gallium phosphide nano-waveguides.

PMID: 33820169
Opt Express. 2021 Mar 29;29(7):10307-10320. doi: 10.1364/OE.409758.

We designed, fabricated and tested gallium phosphide (GaP) nano-waveguides for second harmonic generation (SHG). We demonstrate SHG in the visible range around 655 nm using modal phase matching. We observe phase matched SHG for different combinations of interacting modes...

Prochlorperazine Withdraws the Delayed Onset Tonic Activity of Unloaded Rat Soleus Muscle: A Pilot Study.

Life (Basel, Switzerland)

Kalashnikov VE, Tyganov SA, Turtikova OV, Kalashnikova EP, Glazova MV, Mirzoev TM, Shenkman BS.
PMID: 34833037
Life (Basel). 2021 Oct 30;11(11). doi: 10.3390/life11111161.

A gradual increase in rat soleus muscle electromyographic (EMG) activity is known to occur after 3-4 days of hindlimb suspension/unloading (HS). The physiological significance and mechanisms of such activity of motoneurons under unloading conditions are currently unclear. Since hyperactivity...

Errors and uncertainties in the measurement of ultrasonic wave attenuation and phase velocity.

IEEE transactions on ultrasonics, ferroelectrics, and frequency control

Kalashnikov AN, Challis RE.
PMID: 16382627
IEEE Trans Ultrason Ferroelectr Freq Control. 2005 Oct;52(10):1754-68. doi: 10.1109/tuffc.2005.1561630.

This paper presents an analysis of the error generation mechanisms that affect the accuracy of measurements of ultrasonic wave attenuation coefficient and phase velocity as functions of frequency. In the first stage of the analysis we show that electronic...

New architectures for feedthrough SAW recursive devices.

In quantum optics and its applications, there is an urgent demand for photon-number resolving detectors. Recently, there appeared multi-pixel counters (MPPC) that are able to distinguish between 1,2,..10 photons. At the same time, strong coupling between different pixels (crosstalk)...

Double chirped-pulse-amplification laser: a way to clean pulses temporally.
